Abstract

The utility model relates to a saccule catheter in a medical appliance. The utility model comprises saccules and a catheter. The utility model is characterized in that annular metal wires which are impermeable to X-ray are evenly distributed and inlaid on the outer wall of a catheter section between two saccules and on the catheter section positioned inside the saccules along axial direction. The saccule catheter has expanding and forming functions, and a certain section for a catheter cavity can be measured with length and positioned. The utility model has the advantages of easy use, and accurate and reliable measurement and positioning.

Description

Can survey the length foley's tube

This utility model relates to the foley's tube in the medical apparatus and instruments.

When implementing stent endoprosthesis in to a certain section (being generally narrow section) of body lumen, need measure the length of this section tube chamber earlier, the intraluminal stent of length selection places in this section tube chamber according to this then.The existing pair of cavity single-bag foley's tube or three-cavity and double-caspula foley's tube are mainly used in human body different parts luminal stenosis section are carried out dilation therapy.And they combine with the X ray photographing device certain section tube chamber are carried out X ray when photography, because intravital tube chamber of people and film have certain distance, so the photo of being taken has certain amplification.In addition, when the axis of tube chamber and X ray out of plumb, the tube chamber section of shooting has concentration again.Therefore, combined with the X ray photographing device by existing pair of cavity single-bag foley's tube or three-cavity and double-caspula foley's tube, certain section captured tube chamber has error all the time according to shadow length and physical length.Thereby make between the physical length of the length of selected intraluminal stent and certain section tube chamber and have error.Intraluminal stent is long, may influence the normal function of tube chamber itself or produce complication; Intraluminal stent is too short, then can not effectively eliminate the luminal stenosis phenomenon.

The purpose of this utility model is to provide the foley's tube that can measure certain partial-length of body lumen, and being used of it and X ray photographing device can be measured certain partial-length of body lumen accurately.

For achieving the above object, this utility model adopts following scheme:

Two cavity single-bag foley's tubes that this utility model provides include a conduit 3 and a sacculus 1, sacculus 1 is wrapped on the conduit 3, two tube chambers are arranged in the conduit 3, one of them tube chamber communicates with this sacculus 1, is positioned at that the run outer wall of sacculus 1 is uniform vertically to stud with roentgenopaque annular metal silk 2.The three-cavity and double-caspula foley's tube that this utility model provides includes a conduit 3 and two sacculus 1a and 1b, sacculus 1a and 1b are wrapped on the conduit 3, three tube chambers are arranged in the conduit 3, wherein two tube chambers communicate respectively with two sacculus 1a and 1b, stud with roentgenopaque annular metal silk 2 from one sacculus 1b terminal run outer wall to last sacculus 1a end in back is uniform vertically.

When needing to survey certain luminal stenosis segment length, under x-ray television system monitors, the sacculus 1 of two cavity single-bag foley's tubes is inserted the stenosis of tube chamber, with the low-density contrast agent that sacculus 1 is full, at this moment, the narrow positions of tube chamber can produce impression to sacculus.Owing to be evenly equipped with roentgenopaque annular metal silk 2 vertically on the run in the sacculus 1, so can determine the true length of this luminal stenosis section by the corresponding some annular metal silks 2 separately of impression.The three-cavity and double-caspula foley's tube then is mainly used in measures the distance of a certain tube chamber section start to stenosis.When prostate-urethra length is measured, under x-ray television system monitors, last sacculus 1a is inserted intravesical, after injecting contrast agent and making its full expanding, tractive conduit 3 makes last sacculus 1a be resisted against the neck of bladder place.Subsequently, full again back one sacculus 1b, at this moment, the membranous part sphincter produces impression to back one sacculus 1b, and the pairing annular metal silk of this impression to the distance between last sacculus 1a rear end annular metal silk is prostate-urethra length.

In above-mentioned measurement, supravasal annular metal silk plays scale usefulness, simultaneously, because sacculus is supported in the tube chamber, the run that has the annular metal silk is coaxial with tested tube chamber section, and during imaging, the run that has an annular metal silk together amplifies with tested tube chamber section or dwindles.Therefore, no matter be exaggerated during tested tube chamber section imaging or shorten, the length value of the tested tube chamber section of being read by annular metal silk on the conduit is physical length.To sum up, the foley's tube that this utility model provides also can be measured the length of tube chamber section easy, more accurately except that the function of the original expanding and shaping of tool.In addition, by the skeleton position of supravasal annular metal silk and human body corresponding position, also can determine the position at certain section tube chamber two ends.

Description of drawings:

Fig. 1, this utility model are the structure chart of two cavity single-bag foley's tube one embodiment;

Fig. 2, this utility model are the structure chart of three-cavity and double-caspula foley's tube one embodiment.

Further specify this utility model below in conjunction with drawings and Examples.

The overall structure of shown in Figure 1 pair of cavity single-bag foley's tube and the material of each parts are identical with existing pair of cavity single-bag foley's tube, and sacculus 1 is located at the front end place of conduit 3 among Fig. 1, and conduit 3 is provided with conduit tailstock 5 and sacculus tailstock 4.The overall structure of three-cavity and double-caspula foley's tube shown in Figure 2 and the material of each parts are also identical with existing three-cavity and double-caspula foley's tube.Among Fig. 2, be wrapped in the leading portion that two sacculus 1a on the conduit 3 and 1b are positioned at conduit 3, conduit tailstock 5 is connected to the rear end of conduit 3.Also be provided with sacculus tailstock 4a and the 4b corresponding on the back segment of conduit 3 with sacculus 1a and 1b.Among Fig. 1, Fig. 2, the material of annular metal silk 2 is lead or rustless steel on the conduit 3.On conduit 3, also can adhere to barium sulfate and make scale, if adopt barium sulfate to make scale mark, can be when processing conduit 2 directly with the barium sulfate injection moulding in the tube wall of conduit 2.The spacing of each annular metal silk 2 is 0.5～1cm on the conduit 3.For two cavity single-bag foley's tubes, the diameter and the length of sacculus 1 can be made various sizes series, to be fit to the tube chamber of human body different parts.Equally, for the three-cavity and double-caspula foley's tube, can make the distance between sacculus 1a and 1b is various sizes, to be fit to the tube chamber of human body different parts.
