Description

Description Syringe storage case Technical field

The present invention relates to a syringe storage case, and particularly to a syringe storage case suitable for an insulin syringe. Background art

Conventionally, various syringes have been provided for a patient to perform insulin injection. For example, the syringe 80 shown in the exploded perspective view of FIG. 1 generally includes a cap 82, a force cartridge holder 84, and a syringe body 86, and a cartridge 70 containing an inulin injection solution is used as a cartridge holder. Insert the cartridge holder 84 into the cartridge holder 84 and attach the injection needle 50 to use. The injection needle 50 is a double-edged needle fixed to the needle holder 52, and has an inner thread on the inner peripheral surface of the needle holder 52.

(Not shown) is screwed into the external screw 85 of the force cartridge holder 84 so that the proximal end 50 b of the injection needle 50 passes through the sealing stopper of the cartridge 70. I have.

By the way, generally, one insulin cartridge 70 is divided into small portions and used for a plurality of injections. However, the injection needle 50 is replaced with a new one every time to prevent infection.

The injection needle 50 is generally provided in the form of a needle unit 60. A new injection needle unit 60 has a needle cap 54 attached to the distal end 50a of the injection needle 50 as shown in the external view of Fig. 2 and the exploded perspective view of Fig. 3 in addition to Fig. 1, for example. The needle holder 52 is accommodated in the needle cover 56 while being non-rotatably fitted to the peripheral surface of the needle cover 56, and is provided around the opening 57 of the needle cover 56. A sterile seal 59 is adhered to the flange 58 and sealed. The sterile seal 59 is provided with a tab 59a for easy peeling.

When attaching the injection needle 50 to the syringe 80, as shown in FIG. Hold the needle unit 60 from which the gap 59 has been peeled off with one hand, and with the other hand, hold the syringe 80 (specifically, the cartridge holder 84) that houses the force cartridge 70 and connects the syringe body 86. The needle unit 60 is brought closer to the outer screw 85 of the cartridge holder 84 of the syringe 80, and the needle unit 60 is turned. Screw it to the external screw 8 5 of 4. Thus, the injection needle 50 is attached.

At the time of injection, the needle cover 56 is pulled straight in the axial direction and removed, and the gold cap 54 is removed.

After the injection is completed, the needle cap 54 is attached, the needle cover 56 is fitted to the needle holder 52, and the needle cover 56 is turned in the opposite direction to that at the time of mounting the injection needle, and the injection needle 50 is needled. Remove the needle unit 60 housed in the force bar 56 from the syringe 80. As a result, the injection money +50 is collected while being stored in the needle cover 56.

When setting the dose, turn the rotary operation dial 88 provided at the end of the syringe body 86 while looking at the display window 87 of the syringe body 86 as shown in FIG. Set the indicated dosage unit. Then, the injection button 89 of the syringe body 86 is moved toward the injection needle 50 to perform injection.

By the way, as described above, when attaching / detaching the injection needle 50 to / from the syringe 80 or setting the dose, use a small fingertip such as the needle unit 60 or the rotary operation dial 88 of the syringe 80. It is necessary to turn while pinching. Such detailed operations are difficult for some diabetics. Disclosure of the invention

Therefore, a technical problem of the present invention is to make it possible to easily perform a rotating operation such as attaching and detaching a syringe needle.

The present invention provides a syringe storage case having the following configuration in order to solve the above technical problems.

The syringe storage case is of a type that stores at least a syringe. A needle unit in which a needle unit accommodating a double-needle needle is inserted into a syringe storage case so that the proximal end side of the needle is exposed upward and cannot rotate freely; A rotation operation dial hole provided at the end of the syringe and a rotation operation dial hole into which the rotation operation dial can be non-rotatably inserted, or one or both of them are provided.

In the above configuration, the injection needle unit hole is used for an operation of attaching and detaching the injection needle to and from the syringe. When attaching the injection needle, insert the needle unit into the injection needle unit hole of the syringe storage case, and hold it with the proximal end of the injection needle exposed upward. Then, while holding the injector storage case with one hand, turn the needle attachment part of the syringe close to the needle unit with the other hand and turn it. Since the injection unit engages with the injection unit hole and does not rotate, the injection needle is attached to the syringe by the relative rotation between the injection unit and the syringe. To remove the needle, simply rotate the syringe in the opposite direction.

The rotary operation dial hole is used for the rotation operation of the syringe, such as setting the dose. In other words, hold the syringe storage case with one hand, hold the syringe with the other hand, insert the rotation dial of the syringe into the rotation dial hole of the injector storage case, and turn it. Since the rotary operation dial engages with the rotary operation dial hole and does not rotate, the syringe body and the rotary operation dial rotate relative to each other. Thus, the rotary operation dial can be turned.

According to the above configuration, a relatively simple operation of holding down the syringe storage case and turning the syringe while holding it can perform a rotating operation such as an attaching / detaching operation of the syringe needle. The details of pinching and turning the dial with your fingertips! / No operation is required.

Therefore, the rotation operation such as the attachment and detachment of the injection ^ "can be easily performed.

In the above configuration, the injection needle unit hole and / or the rotary operation dial hole can be provided at an appropriate position of the syringe storage case. For example, if it is provided on the bottom of the syringe storage case, it is necessary to turn the syringe storage case upside down when attaching the needle and setting the dose, etc. If a hole is formed in the open part of the syringe storage case When attaching the needle, setting the dose or setting the dose, etc., the hole of the syringe storage case will be used in the open state, but the injection unit and / or the rotary dial hole will always be used. You can make it invisible.

Preferably, the injection needle unit hole and / or the rotary operation dial hole are provided on the upper surface of the syringe storage case. According to the above configuration, when the injection needle is attached or the dose is set, the syringe storage case is used.

The syringe needle unit hole and Z or rotary operation dial hole can be used without closing the syringe case and turning the syringe storage case over, which makes operation easy.

Preferably, a non-slip member is provided on the back surface of the surface on which the injection hole and Z or the rotary operation dial hole is formed.

In the above configuration, a non-slip material such as rubber or sponge is used as the non-slip member. According to the above configuration, the syringe storage case can be pressed down with a small force so as not to move, and the operation of attaching and detaching the injection needle and the operation of setting the Z or the dose can be performed, which further facilitates the operation.

Hereinafter, a syringe storage case 10 according to an embodiment of the present invention will be described with reference to the drawings.

The syringe storage case 10 is configured substantially in the same manner as the conventional case, and the upper lid 12 opens and closes about the coupling portion 11 with respect to the case body 14. The syringe storage case 10 is configured to store a syringe 80, a needle unit 60, and a cartridge 70.

The upper lid 12 is different from the conventional one, and on its upper surface, a needle operation unit hole 12 a for inserting the needle unit 60, and a rotation operation dial hole 1 2 b for inserting the rotation operation dial 8 8 of the syringe 80. Are formed. As shown in the perspective view of FIG. 6, when the needle unit 60 is inserted with its tapered side down, the needle unit 60 becomes the conical portion 5 6 of the needle cover 56. a engages with the injection needle unit hole 12a, and is held in a state in which the proximal end 50b of the injection needle 50 is exposed upward from the opening 57. Specifically, streaky projections 56 s extending in the axial direction are formed in the conical portion 56 a of the needle cover 56 at appropriate intervals in the circumferential direction. The projections and depressions are formed in a substantially transferred shape. That is, a groove 12 s that engages with the projection 56 s of the needle cover 56 is formed on the substantially conical inner peripheral surface.

As shown in the perspective view of FIG. 7, when the rotary operation dial 88 is inserted with the syringe 80 facing upward, the rotary operation dial hole 8 2b is turned into the rotary operation dial hole 1 2b. To be engaged. Specifically, axially extending grooves 88 t are formed on the substantially cylindrical outer peripheral surface of the rotary operation dial 88 at appropriate intervals in the circumferential direction, and the rotary operation dial hole 1 2 b is The projections and depressions are formed in a substantially transferred shape. That is, the protrusion 12 t that engages with the groove 88 t of the rotary operation dial 88 is formed on the substantially cylindrical inner peripheral surface.

When attaching the injection needle 5 () to the syringe 80, open the upper lid 12 of the syringe storage case 10, take out the syringe 80 and the unused injection needle unit 60 from the inside, and close the upper lid 12. Then, pinch the tab 59 a and peel off the sterile seal 59 from the flange 58 of the injection needle unit 60, insert it into the injection hole 12 a of the top lid 12 of the storage case 10, and open the opening. 57 is facing upward, and the base 50b of the injection needle 50 is exposed.

Next, hold the storage case 10 with one hand so that it does not move, hold the syringe 80 downward with the other hand, and hold the syringe 80 with the outer screw 85 while keeping it perpendicular to the storage case 10. Insert the needle 80 into the internal thread of the needle holder 52 in the injection needle unit 60, and turn the syringe 80 in a predetermined direction. At this time, the conical portion 56 a of the needle cover 56 a engages with the groove a of the injection needle unit hole a and prevents rotation. The outer screw 85 of the syringe 80 can be screwed into the inner screw of the needle holder 52 which is fitted non-rotatably. Once completely screwed up, lift syringe 80 straight up. As a result, the needle unit 60 is attached to the syringe 80 _c. At the time of injection, the needle cover 56 is removed from the syringe 80, the needle cap 54 is further removed, and the tip 50a side of the injection 10 is exposed for use.

After the injection, attach the needle cap 54 to the injection needle 50, remove the needle cover 56 to the needle holder 52, remove the injection needle 50 from the syringe 80 in the reverse order, and collect it. . In other words, hold the syringe storage case 10 with one hand, hold the syringe 80 downward with the other hand, and insert the needle cover 56 into the injection needle unit hole 12 a of the syringe storage case 10 while keeping it straight. Turn the syringe 80 in the opposite direction to that of the installation, and remove the syringe needle 50 from the syringe 80 along with the needle cap 54 and the needle cover 56.

When operating the rotary operation dial 88 of the syringe 80, as shown in FIG. 7, hold the syringe storage case 10 with one hand (not shown), and use the other hand (not shown) to inject the syringe. Hold the 80 downward and hold it vertically, insert the rotary operation dial 88 of the syringe 80 into the rotary operation dial hole 12b of the syringe storage case 10, and turn the syringe 80. At this time, since the projection 1 2 t of the rotary operation dial hole 1 2 b engages with the groove 8 8 t of the rotary operation dial 88, the rotary operation dial 88 does not rotate, and the main body of the syringe 80 rotates. Dial 8 Rotates with respect to 8. This allows the dosage unit to be set.

To make the above operations even easier, attach a sheet of non-slip material such as rubber or sponge to the back of the case body 14 and move the syringe storage case 10 with a little force. It is preferable to be able to hold it down.

As described above, the use of the syringe storage case 10 eliminates the necessity of pinching and turning the small needle cover 56 or the rotary operation dial 88 with a fingertip. Therefore, if the syringe storage case 10 is used, the operation of attaching and detaching the injection needle 50 becomes easy, and the operation of setting the dose becomes easy.

Note that the present invention is not limited to the above-described embodiment, and can be implemented in other various modes.

For example, the first and rotary operation dial holes 12a and 12b are used to rotate the needle cover 56 or the dial 88 when the needle cover 56 or the dial 88 is received. The shape can be appropriately adjusted according to the shape of the needle cover 56 or the dial 88 so as to prevent the problem. For example, the injection needle unit hole 12a may be shaped to engage with the projection 56X (see FIG. 6) of the cylindrical portion of the needle cover 56.

Alternatively, only one of the first and the rotary operation dial holes 12a and 12b may be provided so as to be used only for attaching or detaching the injection needle 50 or setting the dose. Further, even a single hole can be used for both the operation of attaching and detaching the injection needle 50 and setting the dose depending on the shape of the needle cover 56 and the rotary operation dial 88. .
