Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure drainage, in particular to a negative pressure drainage cup. Background Art

[0002] VSD negative pressure drainage is a method for treating wounds and deep drainage. It can remove secretions and necrotic tissues from cavities or wounds, and has a good therapeutic effect on internal diseases that are difficult to treat, such as osteomyelitis. Its main function is to drain tissue fluid, pus, blood clots, and necrotic tissues produced by the wound. Most of the negative pressure drainage sets on the market now are pipeline drainage, and the drainage pipeline is inserted into the dressing, and the exudate, pus, blood clots, necrotic tissue, etc. are led away from the original place or discharged from the body to the drainage can through the negative pressure tube, so as to keep the wound clean and dry, reduce pressure, relieve pain, reduce inflammation, prevent the spread of inflammation, help inflammation subside, reduce damage to surrounding tissues and the possibility of combined infection, and facilitate wound healing. When implementing closed drainage, the negative pressure drainage set is generally not replaced for 3-7 days or even longer.

[0003] At present, drainage is increasingly used in clinical practice. Practice has shown that in most cases, negative pressure drainage is needed to drain the fluid from the tissue fissures, body cavities, and visceral tubes of the human body away from their original locations or out of the body. Negative pressure drainage has also been fully recognized in clinical applications. Initially, hospitals all used central negative pressure suction, and its biggest drawback was that it was inflexible. Patients had to rely on the hospital's negative pressure system and could not move around at will. This was simply not possible in some hospitals with poor medical conditions and in the wild. In order to solve this problem, people developed a negative pressure drainage bottle, which is to block the entrance and exit of a container, and form a negative pressure in the container after suction with the help of an external negative pressure device. Then, equipped with instruments such as guide needles and guide tubes, a simple negative pressure drainage system was formed, which is the negative pressure drainage bottle currently used in clinical practice.

[0004] However, the negative pressure drainage bottles currently on the market have major defects: the drainage bottle cannot tip over, and the patient cannot be moved at will. If the drainage bottle tips over due to movement or turning over, the exudate in the bottle can easily be sucked into the instrument, causing blockage and making the negative pressure machine unable to operate normally. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a negative pressure drainage jar with a simple structure, convenient patient movement, stability and reliability.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A negative pressure drainage can includes a drainage can, wherein the drainage can is connected to a liquid inlet pipe at the can mouth, and the drainage can is also connected to a negative pressure component at the can mouth, which keeps the negative pressure port above the liquid level in the drainage can at all times to maintain the negative pressure effect in the drainage can when the drainage can is turned over.

[0008] As a further improvement of the above technical solution:

[0009] The negative pressure assembly includes a negative pressure tube and a floating component. One end of the negative pressure tube is connected to an external negative pressure instrument, and the other end extends into the drainage tank. The floating component is fixedly connected to the end of the negative pressure tube extending into the drainage tank.

[0010] The end of the negative pressure tube is bent upward, and the floating component is fixedly connected to the bent portion of the end of the negative pressure tube.

[0011] The end of the negative pressure tube is provided with a water-blocking and breathable membrane.

[0012] The floating member is configured as a structure that is wide at the top and narrow at the bottom, wherein the wide upper body is an air sac, and the narrow lower body is a solid sphere, and the air sac is fixedly connected to the bent portion of the negative pressure tube end.

[0013] A telescopic portion is provided on the negative pressure tube between the drainage tank opening and the end portion.

[0014] The telescopic portion is configured as a foldable telescopic tube.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] When in use, the liquid inlet tube is connected to the dressing on the patient's wound surface, and is connected to an external negative pressure instrument through the negative pressure component to generate negative pressure in the drainage cup, so that the exudate on the wound surface is drained into the drainage cup. Compared with the existing negative pressure drainage bottle, the negative pressure component of the utility model can always keep the negative pressure port above the liquid level in the drainage cup when the drainage cup is turned over arbitrarily, avoiding the exudate in the drainage cup from entering through the negative pressure port to cause blockage and causing the negative pressure instrument to fail to operate normally. It is convenient for the patient to move, while ensuring the continuous negative pressure effect in the drainage cup and the normal operation of the external negative pressure instrument, which is stable and reliable.

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, the negative pressure drainage cup of this embodiment includes a drainage cup 1, and the drainage cup 1 is connected to a liquid inlet pipe 2 at the cup mouth. The drainage cup 1 is also connected to a negative pressure component 3 at the cup mouth, which keeps the negative pressure port above the liquid level in the drainage cup 1 to maintain the negative pressure effect in the drainage cup 1 when the drainage cup 1 is turned over. When in use, the liquid inlet pipe 2 is connected to the dressing on the patient's wound surface, and the negative pressure component 3 is connected to the external negative pressure instrument to generate negative pressure in the drainage cup 1, so that the exudate on the wound surface is drained into the drainage cup 1. Compared with the existing negative pressure drainage bottle, the negative pressure component 3 of the utility model can always keep the negative pressure port above the liquid level in the drainage cup 1 when the drainage cup 1 is turned over at will, so as to avoid the exudate in the drainage cup 1 from entering from the negative pressure port to cause blockage and the negative pressure instrument cannot operate normally, which is convenient for the patient to move, and at the same time ensures the continuous negative pressure effect in the drainage cup 1 and the normal operation of the external negative pressure instrument, which is stable and reliable.

[0022] In this embodiment, the negative pressure assembly 3 includes a negative pressure tube 31 and a floating member 32.
