Description

Technical Field

[0001] The utility model relates to the technical field of general nursing, in particular to a negative pressure drainage device for wounds. Background Art

[0002] Negative pressure drainage device is a medical device commonly used to treat wound drainage. It is based on the attraction of negative pressure to remove liquid, gas or pus inside or on the surface of the body. It is widely used in nursing fields such as surgical operations, trauma treatment, and chronic ulcer treatment.

[0003] According to the existing patent publication number: CN216169090U, a negative pressure drainage device includes a negative pressure drainage ball and a liquid collection device; a drainage tube is provided at the top of the negative pressure drainage ball, a one-way valve is provided at the bottom of the negative pressure drainage ball, and a connecting tube is provided at the one-way valve; a drainage port and an air port are provided at the top of the liquid collection device, a connecting piece is provided at the drainage port, an air pipe is provided at the air port, and a negative pressure device is provided at the other end of the air pipe. The device can absorb a small amount of drainage liquid through the negative pressure drainage ball and the one-way valve; and can absorb a large amount of drainage liquid through the liquid collection device and the negative pressure device, but the following defects are exposed during use:

[0004] 1. When the drainage tube is connected to the liquid collecting tank, in order to facilitate the replacement of the liquid collecting tank, it is usually connected by direct plugging and unplugging. However, when the drainage tube is accidentally pulled by external force, the drainage tube is easy to fall off from the liquid collecting tank, causing the connection part to be contaminated.

[0005] 2. At the same time, in order to provide a larger range of motion, the drainage tube is usually longer, but during use, the drainage tube is easy to get tangled together and bend, which may cause blockage of the drainage tube or obstruction of the flow of exudate, affecting the negative pressure drainage effect. Utility Model Content

[0006] The purpose of the utility model is to provide a negative pressure drainage device for wounds, so as to solve the problems of the existing negative pressure drainage device in the use process mentioned in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A negative pressure drainage device for wounds, comprising a liquid collecting tank, a connecting pipe is installed on the top of the liquid collecting tank, and a plurality of groups of limiting grooves are provided on the surface of the connecting pipe in an annular shape;

[0009] The drainage tube is inserted into the limiting groove at one end of the connecting tube through a plurality of limiting rods fixed at one end;

[0010] Soft barbs, which are symmetrically arranged at both ends of the limiting rod;

[0019] Preferably, a storage box for accommodating the storage clip is installed on the surface of the liquid collecting tank, and the limiting rod is matched with the limiting groove.

[0020] Preferably, a plurality of groups of card slots are equidistantly provided on the surface of the storage clip, and friction pads for improving the friction effect are fitted on the surfaces of the card slots.

[0032] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] Example: Figure 1 and Figure 2 As shown, the negative pressure drainage device for wounds includes a liquid collecting tank 1. A handle 2 is installed on the surface of the liquid collecting tank 1 for easy access by personnel, thereby improving overall portability. The label area 3 is used to post or record patient information. The end of the drainage tube 7 is placed in the patient's drainage site, and the one-way valve 10 is closed. By pressing the negative pressure drainage ball 9, a certain degree of negative pressure is generated. The one-way valve 10 is opened to allow the internal liquid at the patient's wound to flow through the drainage tube 7 into the liquid collecting tank 1 for collection. At the same time, the scale line 5 can be observed to check the collected liquid. After reaching a certain level, the drain valve 4 can be opened to discharge the liquid inside the liquid collecting tank 1 from the drain valve 4. The clamp 11 connected to the surface of the drainage tube 7 and the branch pipe 12 is used to control the opening and closing of the drainage tube 7 and the branch pipe 12.

[0034] like Figure 1 Figure 3As shown, a limiting rod 14 is installed at one end of the surface of the drainage tube 7, which matches the limiting groove 17 at one end of the connecting tube 13. When connecting them, the positions of multiple groups of limiting rods 14 can be first aligned with the positions of the limiting grooves 17, and then they can be plugged inward and fixed. Soft barbs 16 with self-elasticity are arranged on both sides of the limiting rod 14, so that the soft barbs 16 on both sides shrink in the inner avoidance groove 15 during the plugging process. When the limiting rod 14 is fully connected, the limiting rod 14 extends a certain distance, and then the soft barbs 16 recover their original state with their own resilience, and unfold from the avoidance groove 15, and are located on one side of the connecting tube 13, so as to limit the drainage tube 7 and reduce the detachment of the drainage tube 7. The sealing sheet arranged at the connecting end of the connecting tube 13 and the drainage tube 7 is made of silicone material, which can improve the sealing of the connection.

[0035] like Figure 1 and Figure 4 As shown, the storage clip 8 is composed of a card slot 18 and a friction pad 19. The friction pad 19 is made of rubber. When the device is in use, the drainage tube 7 can be slightly bent into equidistant lengths according to actual conditions and then embedded in the card slot 18 on the surface of the storage clip 8, so as to reasonably store the drainage tube 7 while not making it appear messy, thereby reducing the contact between the drainage tube 7 and the ground due to its long length, thereby reducing the contamination of the drainage tube 7. When the device is idle, the storage box 6 can be opened and the storage clip 8 can be placed in the storage box 6 for storage and preservation for the next use.

[0036] Working principle: When the drainage tube 7 is docked with the connecting tube 13, the limiting rod 14 at one end of the drainage tube 7 is connected to the limiting groove 17 at one end of the connecting tube 13. During this process, the soft barbs 16 on both sides of the limiting rod 14 will shrink into the avoidance groove 15, and will recover to their original state with their own elasticity after being fully connected, thereby limiting the drainage tube 7, thereby reducing the drainage tube 7 from falling off from the liquid collecting tank 1 when accidentally pulled by external force. According to the actual situation, the drainage tube 7 is slightly bent into equidistant lengths and then embedded in the card groove 18 on the surface of the storage clip 8 to limit the drainage tube 7. To store it reasonably without making it look messy, put the end of the drainage tube 7 into the patient's drainage place, close the one-way valve 10, and generate a certain degree of negative pressure by pressing the negative pressure drainage ball 9; open the one-way valve 10, so that the internal liquid of the patient's wound flows into the liquid collecting tank 1 through the drainage tube 7 for collection, and the scale line 5 can be observed to check the collected liquid. After a certain level, the drain valve 4 can be opened to discharge the liquid inside the liquid collecting tank 1 from the drain valve 4, and the clamp 11 connected to the surface of the drainage tube 7 and the branch pipe 12 is used to control the opening and closing of the drainage tube 7 and the branch pipe 12.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
