Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a long-term hemodialysis catheter. Background Technology

[0002] A long-term hemodialysis catheter is a medical device used for long-term hemodialysis treatment. It primarily establishes vascular access for patients with conditions such as kidney failure that require long-term hemodialysis. This catheter is typically made of soft medical materials, with one end inserted into the patient's central vein and the other end connected externally to the dialysis machine. Compared to temporary dialysis catheters, it can be used for a longer period, ensuring stable hemodialysis for the patient over a longer duration.

[0003] During the use of a long-term hemodialysis catheter, the two branch tubes connected to it are exposed, and the two branch tubes are prone to getting tangled together, which affects the use of the long-term hemodialysis catheter. Utility Model Content

[0004] The purpose of this invention is to provide a long-term hemodialysis catheter that solves the problem of easy entanglement between the two branch tubes in the prior art.

[0005] This utility model provides the following technical solution: a long-term hemodialysis catheter, including a long-term hemodialysis catheter body, a branch tube fixedly connected to the end of the long-term hemodialysis catheter body, an exposed part protection mechanism provided on the outer wall of the long-term hemodialysis catheter body, and a hollow protection mechanism provided on the top of the exposed part protection mechanism.

[0006] The exposed part protection mechanism includes a protective frame, which is fixedly installed on the outer wall of the long-term hemodialysis catheter body. A protrusion is fixedly installed on the right side of the protective frame. A rotating block is rotatably connected to the outer wall of the inner side of the protrusion. A protective cover is fixedly installed at the end of the rotating block. A protruding ear is fixedly installed on the outer wall of the protective cover. A connector tube is fixedly installed on the right side of the inner wall of the protective frame. The end of the branch tube away from the long-term hemodialysis catheter body is movably inserted into the inner cavity of the connector tube.

[0007] As a preferred embodiment of the above technical solution, a circular through hole is provided on the outer surface of the protective frame, and a breathable mesh is fixedly installed on the inner wall of the circular through hole.

[0008] The above technical solution, through the design of the breathable mesh, improves the air permeability of the inner cavity of the protective frame.

[0009] As a preferred embodiment of the above technical solution, a groove is provided on the top of the protective frame, and a magnetic block is fixedly installed on the inner wall of the groove. The top of the magnetic block is movably connected to the bottom of the protective cover.

[0010] The above technical solution, through the design of the magnetic block, allows the protective cover to be temporarily locked to the top of the protective frame, making it easy to open and close the protective cover.

[0011] As a preferred embodiment of the above technical solution, the hollowed-out protective mechanism includes a circular base, which is fixedly installed on the top of the protective cover, and a connecting sleeve is detachably connected to the outer wall of the circular base.

[0012] As a preferred embodiment of the above technical solution, a positioning bolt is threaded onto the outer wall of the connecting sleeve, and the threaded end of the positioning bolt is movably connected to the outer wall of the circular seat.

[0013] Through the above technical solution, the design of the positioning bolt allows for a detachable connection between the circular seat and the connecting sleeve, enabling users to selectively install the entire crossbar.

[0014] As a preferred embodiment of the above technical solution, a crossbar is fixedly installed on the outer wall of the connecting sleeve, and a rubber protrusion strip is fixedly connected to the top of the crossbar.

[0015] The above technical solution, through the design of the crossbar, can form a hollow frame to protect the inserted part of the long-term hemodialysis catheter.

[0016] As a preferred embodiment of the above technical solution, a circular plate is fixedly installed at the bottom of the end of the crossbar away from the connecting sleeve, and a sponge seat is fixedly installed at the bottom of the circular plate.

[0017] The above technical solution, through the design of the sponge seat, allows for a flexible connection between the end of the crossbar and the patient's skin, ensuring patient comfort.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model, through the cooperation of a protective frame and a protective cover, can fit snugly against the patient's skin to form a protective cavity, storing and protecting the branch tube within the cavity, while also protecting the branch tube and extending its service life. Furthermore, through the design of the plug-in tube, the user can insert the end of the branch tube into the plug-in tube to achieve a dustproof function for the end, avoiding the problem of the branch tube being easily contaminated, and can also lock the position of the branch tube to prevent the two branch tubes from easily getting tangled together, facilitating the normal use of the branch tube.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figures 1-4 As shown, this utility model provides a technical solution: a long-term hemodialysis catheter, including a long-term hemodialysis catheter body 1, a branch tube 11 fixedly connected to the end of the long-term hemodialysis catheter body 1, an exposed part protection mechanism 2 provided on the outer wall of the long-term hemodialysis catheter body 1, a hollow protection mechanism 3 provided on the top of the exposed part protection mechanism 2, the exposed part protection mechanism 2 including a protective frame 21, the protective frame 21 fixedly installed on the outer wall of the long-term hemodialysis catheter body 1, a protrusion 22 fixedly installed on the right side of the protective frame 21, a rotating block 23 rotatably connected to the outer wall of the inner side of the protrusion 22, a protective cover 24 fixedly installed at the end of the rotating block 23, a protruding ear 25 fixedly installed on the outer wall of the protective cover 24, and a connector tube 28 fixedly installed on the right side of the inner wall of the protective frame 21. One end of the branch tube 11, away from the main body 1 of the long-term hemodialysis catheter, is movably inserted into the inner cavity of the insertion tube 28. Double-sided tape is pre-attached to the bottom of the protective frame 21, and then the protective frame 21 is attached to the patient's skin using the double-sided tape. The protective cover 24, in conjunction with the protective frame 21, forms a protective cavity at the patient's skin, housing and protecting the branch tube 11 within this cavity. The operator can insert the end of the branch tube 11 into the insertion tube 28 to prevent the branch tube 11 from being easily contaminated, while also locking the position of the branch tube 11 to prevent the two branch tubes 11 from easily tangling. Through the design of the protrusion 22 and the rotating block 23, the protective cover 24 is rotatably connected to the protective frame 21. Through the design of the protruding ear 25, it is easy for the user to open the protective cover 24.

[0027] As one implementation method in this embodiment, such as Figure 2 , Figure 3 As shown, a circular through hole is provided on the outer surface of the protective frame 21, and a breathable mesh 27 is fixedly installed on the inner wall of the circular through hole. A groove is provided on the top of the protective frame 21, and a magnetic block 26 is fixedly installed on the inner wall of the groove. The top of the magnetic block 26 is movably connected to the bottom of the protective cover 24. The protective cover 24 is made of iron alloy. The protective cover 24 can be magnetically attracted to the magnetic block 26, so that the protective cover 24 is movably connected to the protective frame 21, which facilitates the fixation of the position of the protective cover 24. Through the design of the breathable mesh 27, the breathability inside the protective frame 21 can be improved, avoiding the problem that poor breathability will affect the skin health of the patient.

[0028] As one implementation method in this embodiment, such as Figure 1 , Figure 4 As shown, the perforated protective mechanism 3 includes a circular base 31, which is fixedly installed on the top of the protective cover 24. A connecting sleeve 32 is detachably connected to the outer wall of the circular base 31. A positioning bolt 321 is threadedly connected to the outer wall of the connecting sleeve 32, and the threaded end of the positioning bolt 321 is movably connected to the outer wall of the circular base 31. A crossbar 33 is fixedly installed on the outer wall of the connecting sleeve 32. A rubber protrusion strip 34 is fixedly connected to the top of the crossbar 33. A circular plate 35 is fixedly installed at the bottom of the end of the crossbar 33 away from the connecting sleeve 32. A sponge seat 36 is fixedly installed at the bottom of the circular plate 35. The 32 is fitted onto the outer wall of the circular seat 31, and then the positioning bolt 321 is tightened, so that the threaded end of the positioning bolt 321 fits against the outer wall of the circular seat 31, realizing the function of locking the position of the crossbar 33 by means of the protective frame 21. Through the overall design of the crossbar 33, a hollow protective structure can be formed on the outside of the skin of the part of the long-term hemodialysis catheter body 1 that is inserted, avoiding the problem that the skin of the part of the long-term hemodialysis catheter body 1 that is inserted is easily squeezed, which may cause the position of the long-term hemodialysis catheter body 1 to shift, thus ensuring the safety of the part of the long-term hemodialysis catheter body 1 that is inserted.

[0029] Working principle: In use, double-sided tape is first attached to the bottom of the protective frame 21, and then the protective frame 21 is attached to the patient's skin with double-sided tape. Then, the end of the branch tube 11 is inserted into the insertion tube 28. Next, the protective cover 24 is rotated to fit against the top of the protective frame 21, thus completing the limiting and protective treatment of the branch tube 11. If it is necessary to protect the skin outside the part of the long-term hemodialysis catheter body 1 that is inserted, the connecting sleeve 32 is fitted onto the outer wall of the circular seat 31, and then the positioning bolt 321 is tightened to lock the position of the crossbar 33. Through the overall design of the crossbar 33, a hollow protective structure can be formed on the skin outside the part of the long-term hemodialysis catheter body 1 that is inserted, thus protecting the part of the long-term hemodialysis catheter body 1 that is inserted.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
