Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary appliances, and in particular relates to an anti-blocking surgical drainage tube. Background Art

[0002] A drainage tube refers to a tube that is inserted into a body cavity or subcutaneous tissue through an incision made in the body to discharge exudate, pus or dirty fluid from the body. For patients undergoing surgical operations, most of them have drainage tubes inserted for drainage. However, when the drainage fluid with blood clots in the patient's body is drained through the drainage tube, the blood clots often block the drainage holes of the drainage tube, resulting in poor drainage. Therefore, a drainage tube that can prevent blockage is needed. After searching, it was found that the application number is "202220372004.2" which discloses "a blockage-resistant abdominal drainage tube", which records "comprising a tube body, an operating port being provided on the inner side of the tube body, a traction line, the traction line passing through the operating port, both ends of the traction line being located outside the tube body, a dredging piece, the dredging piece being located in the tube body, the traction line The lead wire slides around the support part to drive the clearing piece to slide in the tube body, and the inner side of the tube body is also provided with a support part, and the traction wire bypasses the support part, and the support part divides the traction wire into a first part and a second part, and the clearing piece is arranged on the first part or the second part. If the above-mentioned drainage tube is blocked during use, the clearing piece can be used to clear the blockage in the tube for multiple times, thereby avoiding the blockage of the drainage tube. However, there are still certain shortcomings in the use of the above-mentioned drainage tube: since an operation port is provided on the surface of the tube body, although the operation port is a closed protrusion, both ends of the traction rope extend from the operation port to the outside, so it is difficult to determine that there will be no drainage fluid leakage at the operation port during clearing. At the same time, if the patient turns over during use of the above-mentioned drainage tube, the patient's body may press on the tube body and affect the drainage of the drainage fluid.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-Figure 3 The utility model provides the following technical solutions: an anti-blocking surgical drainage tube, comprising a drainage tube body 1, a drainage hole 2 is opened at one end of the drainage tube body 1, the end of the drainage tube body 1 at the end of the drainage hole 2 is in a smooth arc shape, a support tube 3 is installed inside the other end of the drainage tube body 1, a sealing cover 4 is arranged at the other end of the drainage tube body 1, a guide wire 5 is inserted and connected in the middle of the sealing cover 4, a cleaning brush 6 is arranged at one end of the guide wire 5 located in the drainage tube body 1, and a pull ring 7 is connected at the other end of the guide wire 5. A balloon 8 is arranged on the surface of one side of the body 1 close to the drainage hole 2, and a water injection channel 9 and a drug injection channel 10 are respectively opened on the inner wall of the drainage tube body 1, the balloon 8 is connected to the water injection channel 9, and a drug injection hole 11 connected to the drug injection channel 10 is opened on the surface of the drainage tube body 1, an opening for the guide wire 5 to pass through is opened at one end of the support tube 3, and a sealing ring 12 is arranged in the opening, and a water injection pipe 13, a drug injection pipe 14 and a connecting pipe 21 which are respectively connected to the water injection channel 9, the drug injection channel 10 and the drainage tube body 1 are installed on the surface of the drainage tube body 1.

[0017] In this embodiment, a baffle 15 is provided in the support tube 3, the baffle 15 is fixedly connected to the guide wire 5, and the baffle 15 is slidably installed in the support tube 3. A spring 16 is provided on the outside of the guide wire 5, and the two ends of the spring 16 are respectively connected to the baffle 15 and the sealing cover 4.

[0018] Specifically, by pulling the pull ring 7, the guide wire 5 is stretched and dragged to move outward, and then the guide wire 5 will drive the cleaning brush 6 to clean the foreign matter blocking the drainage hole 2, thereby effectively reducing the risk of poor drainage caused by the drainage hole 2 being blocked. The spring 16 is set so that the cleaning brush 6 can automatically return to its position after the pull ring 7 is released, which is more convenient for medical staff to operate.

[0019] In this embodiment, a vent hole 17 is formed on the surface of the baffle 15 .

[0020] Specifically, the vent hole 17 can prevent the guide wire 5 from driving the baffle 15 to move when the pull ring 7 is pulled, thereby preventing negative pressure from being generated in the support tube 3 , thereby effectively reducing the drainage fluid from entering the support tube 3 through the sealing ring 12 .

[0021] In this embodiment, a guide groove 18 is formed on the inner wall of the support tube 3 , and a guide block 19 is installed on the side of the baffle 15 , and the guide block 19 is slidably connected to the guide groove 18 .

[0022] Specifically, the guide block 19 cooperates with the guide groove 18 to facilitate the movement of the baffle 15 .

[0023] In this embodiment, a plurality of reinforcing ribs 20 are disposed on the inner wall of the drainage tube body 1 .

[0024] Specifically, the provided reinforcing ribs 20 can prevent the patient from accidentally pressing the drainage tube body 1 and causing poor drainage of the drainage fluid.

[0025] Working principle: After the drainage tube body 1 is inserted into the patient's body, since one end of the drainage tube body 1 is in a smooth arc shape, it can effectively reduce the risk of scratching the patient's tissue when the drainage tube body 1 is inserted, and the connecting tube 21 is connected to the negative pressure device to drain the drainage fluid. Water is injected into the water injection channel 9 through the water injection pipe 13, and the water will prop up the balloon 8, thereby fixing the drainage tube body 1. Medicine is injected into the medicine injection channel 10 through the medicine injection pipe 14, and the medicine enters the patient's body through the medicine injection hole 11, thereby accelerating the patient's recovery. During the drainage process, if there is a foreign body blocking the drainage hole 2, the medical staff only needs to pull the pull ring 7 outward so that the guide wire 5 drives the cleaning brush 6 can clean the drainage hole 2, thereby effectively reducing the occurrence of poor drainage caused by blockage of the drainage hole 2, and during the stretching and traction of the guide wire 5, the sealing ring 12 can reduce the risk of drainage fluid entering the support tube 3, and the vent 17 opened on the surface of the baffle 15 can effectively prevent the baffle 15 from moving and causing negative pressure in the support tube 3, thereby further reducing the risk of drainage fluid entering the support tube 3, and the sealing cover 4 can prevent drainage fluid from leaking, and the reinforcing ribs 20 can improve the use strength of the drainage tube body 1, reducing the risk of poor drainage caused by the patient accidentally pressing the drainage tube body 1.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
