Description

  The present invention relates to a medical table used in a hospital, and more particularly, to a medical table having a function as a bed in addition to a function as a delivery table or a medical table.

  Many of the delivery tables used for delivery and the examination tables used for patient examinations are widely used in addition to functions as a delivery table or examination table, as well as a bed function. For example, a medical table disclosed in Japanese Patent Laid-Open No. 9-75408 includes a back plate that supports the back of the patient, a seat plate that supports the buttocks, and a pair of left and right support legs that respectively support the left and right heels of the opened patient. While being used as a delivery table or an examination table, it can also be used as a bed by detachably mounting an auxiliary plate on which the patient's leg in a stretched state is placed.

  The seat plate is disposed substantially horizontally, and the back plate is provided to be tiltable with respect to the seat plate. When used as a bed, the back plate is arranged substantially horizontally so that the patient can sleep, and the auxiliary plate is juxtaposed with the seat plate along the longitudinal direction of the medical table. At that time, the unused support leg members are rotated downward on both sides of the auxiliary plate and disposed below. When used as a delivery table or examination table, the auxiliary plate is removed and the back plate is tilted upward. Further, the support leg member is moved upward to be held at a position where the patient's heel can be supported.

Furthermore, there is a medical table that can store an auxiliary plate below the back plate and the seat plate, as in the medical table disclosed in Japanese Patent Application Laid-Open No. 2003-26096. Such a medical table has an advantage that it is not necessary to store the auxiliary plate separately when not in use.

  In the medical table described above, the supporting leg member is provided so as to be rotatable about a horizontal axis extending laterally on both sides of the seat plate. However, when such a configuration is adopted, the support leg member and the support arm that supports the support leg member protrude to the side of the medical table, which hinders the work of doctors and nurses in the bed state. Furthermore, an unexpected situation may occur when clothes such as a doctor or an attendant are caught on the support leg member or the support arm. There is a medical table that solves this problem by shortening the width of the auxiliary plate relative to the width of the seat plate, but when the width of the auxiliary plate is shortened, the region on which the patient's leg is placed becomes narrower. The medical table cannot sufficiently function as a bed.

  When the medical table is transferred between the bed state and the delivery table or the medical table state, it is not allowed to place an extra burden on the patient, so the support leg member is placed in parallel with the seat plate. Must be able to move freely up or down. The present invention solves the above problems, and the support member can move in such a manner, while the support member and the support arm have a structure in which the support member does not protrude sideways in the bed state, Provided is a medical table in which the size of the auxiliary plate is sufficiently wide to satisfy the above requirements.

  The medical table according to the present invention includes a body portion having a seat plate disposed substantially horizontally and a back plate provided to be tiltable, an auxiliary plate juxtaposed with the seat plate, and left and right on the seat plate side. In the medical table provided with two supporting leg members to be arranged, the auxiliary plate being movable up and down and retractable to the main body part, each supporting leg member is interposed via a support arm and a connecting device. The support arm is connected to the main body, and the support arm is rotatably connected around a first rotation axis substantially along the longitudinal direction of the main body and a second rotation axis substantially perpendicular to the first rotation axis. It is connected to the device and can be moved between the standing state and the recumbent state lying on the side of the main body by rotating around the first rotation axis, and around the second rotation axis. Rotate at approximately in the longitudinal direction of the recumbent state and the body part Characterized in that it is movable between a stored state. Furthermore, in the medical table of the present invention, it is preferable that each connecting device is provided in the main body part so as to be freely retractable.

  In the medical table of the present invention, each support leg member is connected to a corresponding support arm via a position adjustment mechanism, and the position adjustment mechanism is substantially vertical in the standing state of the corresponding support arm. A first device that adjusts the orientation of the connected support legs around the rotation axis, and a second device that adjusts the inclination of the connected support legs around at least one of the two rotation axes that are substantially horizontal and parallel to each other. With equipment.

  Furthermore, in the medical table of the present invention, the second device includes the first and second scorpio and the third stigma that meshes with the first scorpio and is connected to the connected support leg member. And the second Kikuza, and the fourth Kikusa connected to the first device, the first and second members arranged opposite to each other, and the interval between the first and second members can be freely adjusted. And the second seat is pivotably provided around one of the two rotating shafts, and the third seat is pivotably provided around the other of the two rotating shafts. The first constellation is fixed to the first member, and the third constellation is disposed between the first constellation and the second member, or the first constellation Is fixed to the second member, the third seat is disposed between the first seat and the first member, and the second seat is the first seat. Fixed to the material, the fourth scorpio is disposed between the second squirrel and the second member, and urges the first squirrel and the third squirrel to engage with each other. And urging means for urging the second and fourth chinsaws to mesh with each other.

  According to the above configuration, in the bed state, the left and right support leg members and the support arms that support them can be stored below the auxiliary plate (and the auxiliary plate moving mechanism). Therefore, according to the present invention, a structure in which the support leg member and the support arm do not protrude sideways is provided to the medical table in the bed state. Furthermore, the support plate can be moved between the stowed state and the standing state while maintaining the auxiliary plate juxtaposed with the seat plate, so that the bed state and the delivery table or examination table state can be used without burdening the patient. Can be transitioned between. And since a support arm is moved in this way, even if it makes the width | variety of an auxiliary | assistant stand the same as the width | variety of a seat plate, a structural problem will not arise. In addition, the distance between the support leg member and the main body can be adjusted in the delivery table or the treatment table by providing the connecting device so that it can be moved back and forth.

  Further, by providing the position adjustment mechanism as described above, the orientation and inclination of the support leg member can be adjusted in the delivery table or the treatment table. By the first device, the direction of the support leg member is adjusted around the vertical axis. For example, if necessary, the left and right support leg members are positioned so as to spread forward, and further, the angle at which they spread can be freely adjusted. . By the second device, the inclination of the support leg member with respect to the horizontal plane can be freely adjusted, and if necessary, the support leg member can be put into a posture suitable for supporting the heel or the back of the knee. Fine adjustment according to the patient is also possible. Such a position adjustment mechanism is achieved, for example, by a configuration using the above-mentioned chrysanthemum.

One of the features of the medical table of the present invention is in the storage of the supporting leg member (8) in the bed state. The medical table according to the present invention is characterized in that the support leg member (8), the support arm (82) and the like can be arranged below the auxiliary plate (4) in a bed state. In the following, the support mechanism (80) of the support member (8) will be described in detail, taking as an example the transition operation from the delivery table state shown in FIG. 2 to the bed state shown in FIG. The structure of the left and right support leg members (8) and their support mechanism (80) is symmetrical with respect to a vertical plane along the longitudinal direction of the medical table, and is arranged on the right side in FIG. That is, the following description will be made mainly with reference to the support member (8) and the support mechanism (80) shown in FIGS.

  FIG. 5 is a plan view of the medical table in the delivery table or the examination table. 6A is a plan view of the connecting device 83 of the support mechanism 80 in this state, FIG. 6B is a side view of the connecting device 83 as viewed from the front of the medical table, and FIG. 6C is a right side of the medical table. FIG. 6D is a perspective view of the connecting device (83) as seen from the side. The connecting device (83) includes a pair of plate-like holding blocks (84) arranged to face each other at the tip of the sliding member (81). These holding blocks (84) are arranged substantially perpendicular to the longitudinal direction of the main body (1) (or the sliding member (81)) so that the support arm (82) can be arranged therebetween. The support arm (82) is spaced slightly longer than the diameter. A rectangular block (85) is provided between the holding blocks (84) so as to be rotatable about a substantially horizontal rotation axis X substantially along the longitudinal direction of the medical table. On one end side of the rectangular block (85), a shaft body (86) along the rotation axis X projects from each of two opposing side surfaces, and these shaft bodies (86) are connected to each holding block (84). ) Are inserted in the holes established in).

A cylindrical member (87) is fixed to the base end of the support arm (82), and the cylindrical member (87) is a shaft body (88) protruding from one side surface of the other end of the rectangular block (85). ) Is inserted. A disc-shaped member for retaining is joined to the tip of the shaft body (88). 6A to 6D, the rotation axis Y is substantially horizontal, in other words, substantially perpendicular to the vertical plane including the rotation axis X.

  In the delivery table or the medical table, the support arm (82) is held in an upright position. A hook (89) for holding the support arm (82) in this state is provided on the upper portion of each holding block (84). These hooks (89) are pivotally supported in the vicinity of the upper corner of the holding block (84), respectively, and are rotatable about a rotation axis along the longitudinal direction of the sliding member (81). These hooks (89) are connected by a bar (90) to which a knob (91) to be gripped when the hook (89) is rotated is fixed, and the bar (90) is connected to a holding block ( 84), the movement of the hook (89) is restricted. In order to hold the support arm (82) in an upright state, the support arm (82) is placed upright between the holding blocks (84), and then the hook (89) is attached to the support arm (82). Rotate toward. A horizontally long flange plate (92) is fixed to the support arm (82), and the flange plate (92) is sandwiched between the bent tip of the hook (89) and the upper portion of the holding block (84). The support arm (82) is held in an upright state.

  When the state changes from the delivery table or the medical table to the bed, the auxiliary plate (4) is pulled out from the main body and lifted up and juxtaposed with the seat plate (2). Thereafter, the patient places both legs supported by the support leg member (8) on the auxiliary plate (4). After that, after the position adjustment mechanism (110) is operated as necessary to adjust the inclination of the support member (8) (for example, the support member (8) is arranged substantially horizontally), the operator The support arm (82) is supported by one arm and the hook (89) is rotated upward by the other arm to unlock the support arm (82). When the lock of the support arm (82) is released, the rectangular block (85) and the support arm (82) can rotate about the rotation axis X. When the operator lowers the arm that supported the support arm (82), as shown in FIG. 7, the support arm (82) is rotated approximately 90 degrees and is lying on its side, and protrudes to the side of the medical table (FIG. 7). Shows a state where both the left and right support arms (82) are lying on the side).

  FIG. 8A is a top view of the coupling device (83) in the state shown in FIG. 7, FIG. 8B is a side view of the coupling device (83) viewed from the front of the medical table, and FIG. 8C is viewed from the right side of the medical table. It is a side view of a coupling device (83). As the rectangular block (85) rotates approximately 90 degrees, the rotation axis Y is substantially vertical. A bar (93) protruding toward the other holding block (84) is fixed to one holding block (84), and the rectangular block (85) is fixed to the bar (93). Is in contact from below, the operating range of the support arm (82) is restricted. The bar (93) is fixed at a position where the support arm (82) is held horizontally lying on its side.

Further, a torsion spring (95) is provided between the flange (94) and the holding block (84). The torsion spring (95) biases the rectangular block (85) in the rotation direction in which the support arm (82) is lifted (counterclockwise about the rotation axis X in FIG. 8B). Thereby, when the support arm (82) is moved, the force to be applied by the operator is reduced.

  A first stopper (96) protrudes from the lower end surface of the rectangular block (85). The first stopper (96) is formed with a first protrusion (97) formed on the outer surface of the cylindrical member (87). As shown in FIG. 7, the contact arm (82) is rotated around the rotation axis Y so as not to move further to the main body (1) side from the state where the support arm (82) is arranged along the short direction of the medical table. The operating range of the support arm (82) is restricted.

  FIG. 9 is a plan view of the medical table in the bed state. From the state shown in FIG. 7, the support arm (82), the position adjustment mechanism (110), and the support leg member (8) are rotated by rotating the support arm (82) forward about the rotation axis Y, so that the auxiliary plate (4) It is arranged below. The support arm (82) is disposed so as to be substantially along the longitudinal direction of the main body (1). 10A is a plan view of the connecting device (83) in the bed state, FIG. 10B is a side view of the connecting device (83) viewed from the front of the medical table, and FIG. 10C is a connecting device viewed from the right side of the medical table ( 83) is a side view.

  A second protrusion (98) is formed on the outer surface of the cylindrical member (87) in addition to the first protrusion (97). In FIG. 10A, the second protrusion (98) is provided at a position shifted about 90 degrees counterclockwise with respect to the rotation axis Y. When the support arm (82) is rotated from the state shown in FIGS. 8A to 8C, the second protrusion (98) contacts the first stopper (96) from the front. Thereby, the operation range of the support arm (82) is regulated so as not to further rotate from the storage position substantially along the longitudinal direction of the medical table.

  A second stopper (99) protruding inward (toward the left) is fixed to the holding block (84) disposed on the main body (1) side. When the support arm (82) rotates about the rotation axis X, the first protrusion (97) contacts the second stopper (99) from above. This prevents the support arm (82) from rotating downward about the rotation axis X along with the rotation of the support arm (82). The holding block (84) arranged on the main body (1) side is provided with a locking member (100) for locking the first protrusion (97) of the support arm (82) in the stored state. Thus, when the first protrusion (97) and the locking member (100) are engaged, the position of the support arm (82) and the position of the support leg member (8) in the housed state are maintained. In this embodiment, a metal strip having a tip portion formed in a hook shape is used as the locking member (100), and the first protrusion (97) is fitted to the tip portion. The transition to the engaged state or the release thereof is performed by elastically deforming the locking member (100) by the contact of the first protrusion (97).

  When shifting from the bed state to the delivery table or the examination table state, an operation in which the operation described above is reversed is performed.
