Description

Technical Field

[0001] The utility model relates to a negative pressure drainer, which is a negative pressure drainer. Background Art

[0002] A negative pressure drain is a medical device used in negative pressure wound therapy technology. Negative pressure wound therapy technology is a technology that uses a biological semipermeable membrane to close an open wound, uses a special negative pressure machine to generate a certain negative pressure, and acts on the wound after debridement through drainage tubes and dressings to drain the contents of organ tissue cavities or body cavities out of the body; it is used in the chest cavity, brain cavity, gastrointestinal tract, bile duct, etc. Its main function is to eliminate inappropriate accumulation of inflammatory exudates, digestive fluids, blood and necrotic tissue in the body, and promote the reduction or closure of the abscess cavity or surgical cavity. This type of negative pressure drain device is generally composed of a drainage tube, a connecting tube and a device body, such as the application number 202122654695.3 disclosed in the Chinese patent document, the authorization announcement date 2022.05.10, and the utility model name "A negative pressure drain device that is easy to operate"; another example is the application number 201810996240.X disclosed in the Chinese patent document, the application publication date 2019.02.12, and the invention name "A disposable drain device for preventing backflow"; however, the above-mentioned products and similar products are inconvenient to use and operate, the workload of medical care is large, and the service life is short. Summary of the invention

[0003] In order to overcome the above shortcomings, the purpose of the utility model is to provide a negative pressure drainage device in the art, so as to solve the technical problems of the existing similar products, such as the inconvenience in use and operation, the large workload of medical care, and the short service life. The purpose is achieved through the following technical solutions.

[0004] A negative pressure drain, the bag body of the negative pressure drain is the body, one side of the cover plate on the top of the body is provided with an air plug, the other side of the cover plate on the top of the body is provided with an elbow, a one-way valve for anti-reflux is provided in the elbow, the elbow is connected to the connector through a connecting pipe, the outer diameter of the connector is provided with a connecting sleeve, the drainage tube is connected to the connector through the connecting sleeve, and a bottom plate is provided at the bottom of the body; the structural design points are as follows: the body, the cover plate and the bottom plate are integrally formed, and the body between the cover plate and the bottom plate is provided with an integrally formed spring, and one end of the elbow and the air plug is connected to the through hole at the cover plate through ultrasonic fusion. The above-mentioned one-way valve adopts an existing one-way ball valve or a one-way elastic sleeve structure, which can realize and achieve anti-reflux.

[0005] The diameter of the device body is smaller than the diameter of the cover plate and the bottom plate. The cover plate and the bottom plate are aligned with the pockets arranged at both ends of the device body. The spring is arranged in the device body in a spiral shape between the cover plate and the bottom plate.

[0006] The air plug and the elbow of the cover plate are eccentrically arranged on one side, and a raised and integrally formed hanging hole edge is provided on the bottom plate edge in the middle below the air plug and the elbow.

[0007] The utility model is convenient to use and operate, has good sealing and drainage effects, and has a long service life; the utility model is suitable for use as a negative pressure drainer, and is a structural improvement of similar products. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Now, in conjunction with the accompanying drawings, its structure and use are further described. Figure 1-Figure 3 As shown, the bag body of the negative pressure drainage device is a body 6, a gas plug 1 is provided on one side of the cover plate 4 at the top of the body, an elbow 2 is provided on the other side of the cover plate at the top of the body, a one-way valve 3 for anti-reflux is provided in the elbow, the elbow is connected to the connector 8 through a connecting pipe 9, a connecting sleeve 10 is provided on the outer diameter of the connector, the drainage tube is connected to the connector through the connecting sleeve, and a bottom plate 11 is provided at the bottom of the body. While the above-mentioned body, the cover plate and the bottom plate are integrally formed, the body between the cover plate and the bottom plate is provided with an integrally formed spring 5, and one end of the elbow and the gas plug is connected to the through hole at the cover plate by ultrasonic fusion. The diameter of the body is smaller than the diameter of the cover plate and the bottom plate, and the cover plate and the bottom plate are aligned with the bag openings at both ends of the body, and the spring is spirally arranged in the body between the cover plate and the bottom plate. . The gas plug and the elbow of the cover plate are eccentrically arranged on one side, and the edge of the bottom plate in the middle below the gas plug and the elbow is provided with a raised and integrally formed hanging hole edge 1101. The height of the negative pressure drain is 112±5mm, the thickness is 0.35±0.1mm, the inner diameter is 145±5mm, and the length of the connecting tube is 860±50mm. The negative pressure drain includes two capacity models, of which the C type has a capacity of 1800ml and the D type has a capacity of 1000ml.

[0013] When in use, open the air plug, and after the body of the device is opened, the air intake is completed, the air plug is closed, and the connecting tube is connected to the drainage tube. After the operation, the drainage tube of the surgical site, the accumulated fluid in the surgical site after the operation enters the body of the device through the drainage tube, connecting tube, elbow, and one-way valve. The body of the device can also be hung on the bed through the hanging hole.

[0014] In summary, with the existing products on the market, medical staff need to press the product before use and then connect it to the drainage tube. The negative pressure drain can be directly connected to the drainage tube for use, eliminating a pressing step and reducing the workload of medical staff. At the same time, the existing products on the market generally have another air plug at the elbow, which needs to be opened when in use, and then a tube needs to be plugged in. The body of the device needs to be flattened once before drainage, which is inconvenient to operate.
