TECHNICAL FIELD

[0001] The utility model provides a puncture drainage connecting pipe belongs to medical puncture tool technical field. BACKGROUND

[0002] In modern medical practice, puncture drainage connecting pipes are widely used in surgery, trauma treatment, infection treatment and other scenarios. Their main function is to guide the discharge of body fluids, pus or other harmful substances from the body, thereby promoting wound healing and disease recovery. Traditional puncture drainage connecting pipes usually include a drainage tube body, a drainage cylinder and a sealing device. When in use, the drainage tube is inserted into the lesion site through a puncture needle, and the drainage cylinder is connected to an external collection container to facilitate continuous drainage and monitoring of the drainage fluid. The sealing device is usually provided on the drainage tube and consists of a clamp or a valve.

[0003] However, the traditional puncture drainage connecting pipe has some significant problems in use, especially the manual operation of closing and opening the drainage tube. Specifically, when the collection container needs to be replaced, medical personnel usually need to manually operate the sealing device (such as a clamp or a valve) to close the drainage tube, and then open it after replacing the collection container. This manual operation is time-consuming and labor-intensive. To solve the above problems, a new puncture drainage connecting pipe is needed. SUMMARY

[0004] The technical problem to be solved by the utility model is the time-consuming and labor-intensive way of manually operating the sealing device to close or open the drainage tube.

[0005] To solve the above problems, the utility model provides the following technical scheme: a puncture drainage connecting pipe, comprising a drainage tube, one end of the drainage tube being connected with a connecting cylinder, the other end of the drainage tube being connected with a drainage cylinder, and the drainage tube, the connecting cylinder and the drainage cylinder being in communication with each other; further comprising:

[0006] a sealing film, the sealing film being fixedly arranged in the drainage cylinder; the sealing film being made of elastic material, and a small hole being formed in the middle of the sealing film;

[0007] a plug-in cylinder, the plug-in cylinder being located below the sealing film, and the plug-in cylinder being connected with the drainage cylinder through an adjusting assembly.

[0008] As an improvement, the adjusting assembly comprises a threaded cylinder and an operating block, the threaded cylinder being located in the drainage cylinder and being threadedly connected with the drainage cylinder, and the operating block being located outside the drainage cylinder and being fixedly sleeved on the threaded cylinder.

[0009] As an improvement, the plug-in cylinder is fixedly connected with the threaded cylinder, and the plug-in cylinder and the threaded cylinder are in communication.

[0010] As an improvement, the plug-in cylinder is a conical cylinder, and the small diameter of the plug-in cylinder is close to the sealing film.

[0011] As improved, the drainage tube is a hose, and the drainage barrel is made of hard medical plastic material.

[0012] The utility model discloses beneficial effect has:

[0013] 1, the sealing membrane is fixedly arranged in the drainage barrel, and a small hole is arranged in the middle of the sealing membrane, the elastic sealing membrane is arranged, the drainage tube can be sealed, when the pipeline of the collecting container is inserted, the pipeline of the collecting container passes through the small hole, so that the drainage tube is directly communicated with the collecting container, and when the pipeline of the collecting container is pulled out, the pipeline of the collecting container is separated from the small hole, and the elastic sealing membrane can be resealed, and the staff need not operate the sealing device to change the closed state of the drainage tube, which is very convenient.

[0014] 2, the plug-in barrel is located below the sealing membrane, and the sealing membrane can be in the normally open state when the collecting container is not connected, so that it is suitable for different use scenes. BRIEF DESCRIPTION OF DRAWINGS

[0019] The utility model is further illustrated in connection with the drawings.

[0020] According to Figs. 1-3 As shown: the utility model provides a kind of puncture drainage connecting pipe: including drainage tube 2, drainage tube 2 one end is connected with connecting barrel 1, and drainage tube 2 other end is connected with drainage barrel 3, and drainage tube 2, connecting barrel 1, drainage barrel 3 are interconnected;Further include:

[0021] Sealing membrane 4, sealing membrane 4 is fixedly arranged in drainage barrel 3;Sealing membrane 4 is elastic material, and small hole 5 is arranged in the middle of sealing membrane 4;

[0022] Plug-in barrel 7, plug-in barrel 7 is located below sealing membrane 4, and plug-in barrel 7 is connected with drainage barrel 3 by adjusting assembly.

[0023] As Fig. 3As shown, the adjusting assembly includes a threaded cylinder 6 and an operating block 8. The threaded cylinder 6 is located inside the drainage cylinder 3 and is threadedly connected to the drainage cylinder 3. The operating block 8 is located outside the drainage cylinder 3 and is fixedly sleeved on the threaded cylinder 6. The insertion cylinder 7 is fixedly connected to the threaded cylinder 6 and communicates with it. When the threaded cylinder 6 is rotated via the operating block 8, the insertion cylinder 7 rotates and rises, passing through the sealing membrane 4, thereby connecting the drainage tube 2 and keeping the entire puncture drainage connection tube in a normally open state.

[0024] The insert 7 is a conical tube, and the smaller diameter of the insert 7 is close to the sealing membrane 4, which makes it easy to open the sealing membrane 4.

[0025] The drainage tube 2 is a flexible tube, and the drainage tube 3 is made of rigid medical plastic, which facilitates the normal connection between the threaded tube 6 and the drainage tube 3.

[0026] The principle of this utility model

[0027] like Fig. 3 As shown, when the drainage connection tube provided in this application is not in use, the sealing membrane 4 is fixedly installed in the drainage tube 3 in a normal state. Due to the surface tension and capillary action of the liquid, the accumulated liquid will not flow out of the small hole 5, thus ensuring the sealing of the drainage tube 2. When drainage is required, the pipe of the collection container is directly passed through the inside of the threaded cylinder 6, and then through the small hole 5, thereby connecting the collection container with the drainage tube 2. At this time, the accumulated liquid or pus can enter the drainage tube 3 from the drainage tube 2 and then enter the collection container. When the collection container needs to be replaced, the pipe of the collection container is simply pulled out of the drainage tube 3. At this time, the pipe of the collection container is separated from the sealing membrane 4, and the sealing membrane 4 and the small hole 5 return to their initial state. At this time, the drainage tube 2 is in a re-sealed state, without the need for personnel to operate the sealing device, which is quick and convenient.

[0028] This application also enables the drainage tube 2 to be in a normally open state when the collection container is not used. Simply operate the operating block 8, turn the threaded cylinder 6, and the insert 7 rotates and rises. The insert 7 passes through the small hole 5, causing the small hole 5 to expand, thereby making the drainage tube 2 and the drainage cylinder 3 in a normally open communication state.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
