Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a drainage tube that prevents dislodgement. Background Technology

[0002] In clinical practice, patients with biliary obstruction need to have a biliary drainage tube placed after surgery. Because the drainage tube is long and has been in place for a long time, it is easy for the tube to dislodge if the patient does not handle it properly during activities such as moving and turning over, which can cause secondary injury to the patient, affect postoperative recovery, and increase the patient's financial burden. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides an anti-dislodgement drainage tube, which has the advantage of preventing dislodgement and solves the problem that existing drainage tubes are prone to dislodgement during patient activity, thus affecting the patient's postoperative recovery.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-dislodgement drainage tube, comprising a drainage tube; the drainage tube is provided with an anti-dislodgement component, the anti-dislodgement component comprising:

[0007] A fixing block is fixedly connected to the outer wall of the drainage tube;

[0008] A fixing frame is disposed outside the fixing block;

[0009] The shoulder strap is fixedly connected to the outer wall of the fixed frame;

[0010] A threaded rod passes through and is threadedly connected to the fixed frame;

[0011] A limiting block is rotatably connected to the bottom of the threaded rod;

[0012] A limiting groove is formed on the top of the fixing block.

[0013] Preferably, a guide plate is fixedly connected to the rear side wall of the fixed frame.

[0014] Preferably, a rubber pad is provided on the rear side wall of the fixing frame.

[0015] Preferably, the fixing frame and the rubber pad are provided with a snap-fit ​​assembly, the snap-fit ​​assembly comprising:

[0016] Connecting blocks are symmetrically and fixedly connected to the top and bottom of the fixed frame;

[0017] The locking block is fixedly connected to the outer wall of the rubber pad, and the locking block is engaged in the slot inside the connecting block.

[0018] Preferably, the fixed frame has an arc-shaped edge on the outside.

[0019] Preferably, the top of the fixing frame has a groove, and the threaded rod is located inside the groove.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model provides an anti-dislodgement drainage tube, which has the following beneficial effects:

[0022] This drainage tube features anti-dislodgement properties. The support strap is worn on the patient's body, and the drainage tube and fixing block are inserted into the fixing frame. Then, the threaded rod is rotated. The rotation of the threaded rod, influenced by the threaded connection with the fixing frame, causes the limiting block to move downwards, gradually inserting into the limiting groove. The fixing frame and fixing block are then connected, preventing the drainage tube from falling off the fixing frame during drainage. This solves the problem of existing drainage tubes easily dislodging during patient movement, thus affecting postoperative recovery. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] See Figure 1-4 A drainage tube designed to prevent detachment includes a drainage tube 1; an anti-detachment component 2 is provided on the drainage tube 1, the anti-detachment component 2 including: a fixing block 23, fixedly connected to the outer wall of the drainage tube 1; a fixing frame 22, disposed outside the fixing block 23; a shoulder strap 21, fixedly connected to the outer wall of the fixing frame 22; a threaded rod 24, passing through and threadedly connected to the fixing frame 22; a limiting block 25, rotatably connected to the bottom of the threaded rod 24; and a limiting groove 26, formed at the top of the fixing block 23. A guide plate 4 is fixedly connected to the rear side wall of the fixing frame 22. A rubber pad 5 is provided on the rear side wall of the fixing frame 22.

[0034] In use, medical staff put the carrying strap 21 on the patient's body and insert the drainage tube 1 and the fixing block 23 into the fixing frame 22. Then, they rotate the threaded rod 24. After the threaded rod 24 rotates, the limiting block 25 moves downward due to the threaded connection with the fixing frame 22. The limiting block 25 gradually inserts into the limiting groove 26, and the fixing frame 22 and the fixing block 23 are connected, preventing the drainage tube 1 from falling off the fixing frame 22 during drainage. When the fixing block 23 is inserted into the fixing frame 22 and abuts against one side of the guide plate 4, the limiting block 25 is aligned with the limiting groove 26. At this time, rotating the threaded rod 24 allows the limiting block 25 to quickly insert into the limiting groove 26 to complete the limiting. The guide plate 4 limits the fixing block 23, thereby improving the convenience of connecting the fixing frame 22 and the fixing block 23. The rubber pad 5 on the rear side wall of the fixing frame 22 contacts the patient's chest to prevent the protruding guide plate 4 from causing discomfort to the patient.

[0035] Example 2

[0036] See Figure 1-4 Based on Embodiment 1, auxiliary functions have been added;

[0037] The fixing frame 22 and the rubber pad 5 are provided with a snap-fit ​​assembly 3. The snap-fit ​​assembly 3 includes: a connecting block 31, symmetrically and fixedly connected to the top and bottom of the fixing frame 22; and a snap-fit ​​block 32, fixedly connected to the outer wall of the rubber pad 5, which snaps into a slot within the connecting block 31. The fixing frame 22 has an arc-shaped edge on its exterior. A groove 6 is formed at the top of the fixing frame 22, and the threaded rod 24 is located inside the groove 6.

[0038] After the rubber pad 5 has been used for a period of time, the user applies force to remove the clip 32 from the connecting block 31, thus completing the disassembly of the rubber pad 5. This facilitates cleaning or replacement of the rubber pad 5, ensuring greater hygiene. Compared to right-angled edges, the curved edges of the fixing frame 22 are less likely to cause scratches to the patient, thereby increasing the safety of using the fixing frame 22. The groove 6 at the top of the fixing frame 22 facilitates the rotation of the threaded rod 24 into the groove 6, preventing the threaded rod 24 from protruding from the surface of the fixing frame 22 and causing scratches to the patient.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
