Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a disposable chest drainage tube clamp. Background Art

[0002] Thoracic drainage is a procedure in which a catheter is placed in the pleural cavity through an incision in the chest wall to remove air or fluid. Insertion of the catheter between the ribs is called "intercostal drainage," while removal of a rib and insertion of a thicker catheter through the rib bed is called "intercostal drainage." A catheter with the outer end connected to the drainage bottle below the liquid level, allowing fluid or air to be drawn out of the pleural cavity without returning, is called "closed drainage." A drainage catheter that communicates directly with the outside world is called "open drainage." In clinical practice, it is often necessary to clamp the drainage tube when changing chest drainage bottles or when transferring patients to prevent the backflow of air and drainage fluid into the chest cavity.

[0003] Existing chest drainage tube clamps require medical personnel to use both hands to clamp the drainage tube, which reduces the medical personnel's work efficiency. Moreover, when the medical personnel use one hand to perform other tasks, they cannot use the clamp to clamp the drainage tube, which makes the chest drainage tube clamp very limited.

[0028] Thoracic drainage is a procedure in which a catheter is placed in the pleural cavity through an incision in the chest wall to remove air or fluid. Insertion of the catheter between the ribs is called "intercostal drainage," while removal of a rib and insertion of a thicker catheter through the rib bed is called "intercostal drainage." A catheter with the outer end connected to the drainage bottle below the liquid level, allowing fluid or air to be drawn out of the pleural cavity without returning, is called "closed drainage." A drainage catheter that communicates directly with the outside world is called "open drainage." In clinical practice, it is often necessary to clamp the drainage tube when changing chest drainage bottles or when transferring patients to prevent the backflow of air and drainage fluid into the chest cavity.

[0029] In the related art, when clamping the drainage tube, medical personnel need to use both hands to operate, which reduces the work efficiency of medical personnel. When the medical personnel use one hand to perform other tasks, they cannot use the clamp to clamp the drainage tube, which makes the chest drainage tube clamp have great limitations and reduces the flexibility and practicality of the chest drainage tube clamp.

[0030] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides a disposable chest drainage tube clamp. When the drainage tube 13 needs to be clamped, it is only necessary to hold the outer shell 11 and push the squeezing block 21 inward with the thumb, and squeeze the drainage tube 13 inside the outer shell 11 into the cavity 22. At the same time, the clamping rod 24 clamps the teeth 23 on the squeezing block 21 to fix the squeezing block 21, thereby clamping the drainage tube 13 inside the cavity 22.

[0031] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0032] Combine Figure 1-Figure 3 The embodiment of the present application provides a disposable chest drainage tube clamp, including a clip body 1; the clip body 1 includes: a drainage tube 13 is arranged on the top of the shell 11; the clamping assembly 12 passes through the shell 11 and the drainage tube 13; a clamping assembly 2 is arranged inside the shell 11, and the clamping assembly 2 includes: an extrusion block 21 passing through one side of the shell 11; a cavity 22 is arranged inside the shell 11; a latch 23 is arranged on the extrusion block 21; a clamping rod 24 passes through the top of the shell 11; a first spring 241 is arranged on the outside of the clamping rod 24 and is located inside the shell 11; and a reset assembly 25 is arranged inside the cavity 22.

[0033] When the chest drainage bottle is replaced, the clamping rod 24 is pulled upward so that the clamping rod 24 cannot fix the squeezing block 21. At the same time, the squeezing block 21 is pushed back by the reset assembly 25 to reset the squeezing block 21, thereby restoring the circulation of the drainage tube 13. This improves the convenience and work efficiency of the medical staff in operating the chest drainage tube clamp and increases the flexibility and practicality of the disposable chest drainage tube clamp.

[0034] Specifically, the clip body 1 is a disposable item, eliminating the tedious steps of reuse, cleaning, and disinfection required with traditional drainage clips, reducing medical costs and the risk of cross-infection. Made from high-molecular-weight medical materials, it offers excellent biocompatibility and corrosion resistance, ensuring safety and non-toxicity during use. Its design incorporates a soft yet resilient elastic structure, ensuring a tight clamping seal while minimizing pressure on the patient's tissues.

[0035] In some embodiments, an anti-slip pad 27 is provided on the squeezing block 21 to match the drainage tube 13 and is located inside the shell 11, thereby increasing the anti-slip property of the squeezing block 21 when squeezing the drainage tube 13 and improving the stability and accuracy of the clamping operation.

[0036] Specifically, the surface of the anti-slip pad 27 has granular protrusions, which increase the friction force of squeezing the outer side of the drainage tube 13, thereby achieving an anti-slip effect.

[0037] In some embodiments, a limit plate 242 is provided on the outside of the card rod 24 and is located at the bottom of the first spring 241 to limit the card rod 24 to prevent the card rod 24 from being pulled out of the housing 11 when the card rod 24 is pulled upward.

[0038] In some embodiments, the reset assembly 25 includes: a support plate 251 arranged inside the cavity 22; a second spring 252 is arranged between the support plate 251 and the cavity 22, and when the extrusion block 21 squeezes the drainage tube 13 into the cavity 22, the second spring 252 is in a compressed state. When the clamping rod 24 cannot fix the extrusion block 21, the support plate 251 pushes the extrusion block 21 and the drainage tube 13 to reset through the rebound force of the second spring 252.

[0039] Specifically, the drainage tube 13 on one side of the support plate 251 is squeezed by the squeezing block 21 to seal and block flow, and the two right angles at the opening of the cavity 22 will fold and seal the drainage tube 13 to achieve double sealing, thereby improving the sealing and blocking effect of the disposable chest drainage tube clamp.

[0040] In some embodiments, a slider 26 is provided on the support plate 251 , and a sliding groove 261 that cooperates with the slider 26 is provided on the inner wall of the cavity 22 to support the support plate 251 and increase the stability of the support plate 251 moving in the cavity 22 .

[0041] In some embodiments, the clamping assembly 12 includes: a fixing tube 121 arranged at the top of the outer shell 11; a threaded rod 122 passing through the fixing tube 121; a clamping plate 123 arranged at one end of the threaded rod 122 and located inside the fixing tube 121. By rotating the threaded rod 122, the rotating threaded rod 122 drives the clamping plate 123 to move toward the outside of the drainage tube 13 and clamp the drainage tube 13, so that the outer shell 11 is fixed on the drainage tube 13.

[0042] Specifically, the clamping plate 123 is rotationally connected to the threaded rod 122 , and the movable space in the fixing tube 121 is relatively small, so that the clamping plate 123 cannot rotate along with the threaded rod 122 .

[0043] In some embodiments, a fixing strap 14 is provided on the outside of the shell 11 to facilitate fixing the shell 11 on the patient's chest.

[0044] In some embodiments, a Velcro 141 is provided between the outer shell 11 and the fixing belt 14 so that the outer shell 11 and the fixing belt 14 are bonded together, making it easy to disassemble and assemble the fixing belt 14 .

[0045] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0046] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
