technical field

The invention belongs to the technical field of medical devices, and in particular relates to an abdominal cavity drainage device.

Background technique

After abdominal surgery for patients with liver cancer, gastric cancer, and pancreatic cancer, it is often necessary to place a drainage tube in the patient's abdominal cavity to drain blood, exudate, pus, and other leaks out of the body. At present, clinically, the exudate in abdominal cavity puncture is bandaged with gauze under pressure, but there is a lot of exudate, and the film is loose. If it is not detected in time, the drainage tube will prolapse. If the tube is re-inserted, the pain and cost will increase.

Contents of the invention

The technical problem to be solved by the present invention is to provide a peritoneal fluid drainage device that can adjust the fixed position of the drainage bag, reduce excessive skin pressure at the same position, prevent liquid backflow, and have an alarm function for the above-mentioned deficiencies in the prior art.

For realizing above-mentioned technical purpose, the technical scheme that the present invention takes is:

The liquid receiving bag is provided with an annular diversion wall, which is arranged around the liquid receiving port. The annular diversion wall is connected to the liquid receiving bag. The two sides cooperate to separate the inner space of the liquid-receiving bag into two parts that are mutually sealed. The lower part of the annular diversion wall is provided with a one-way valve. The one-way valve allows the liquid to flow from the liquid-receiving port to the lower part of the liquid-receiving bag, and vice versa. The side of the fluid bag facing away from the abdomen is provided with several rings of concentric fixed rings with different diameters, the fixed ring is sealed and connected with the liquid bag, and the side of the fixed ring facing the liquid bag is provided with a fixed structure; the peritoneal exudate drainage device also It includes several fixing stickers. The shape of the fixing sticker is ring-shaped and the size matches the corresponding fixing ring. One side of the fixing sticker is an adhesive surface, which is attached to the abdomen of the patient. The other side of the fixing sticker is provided with a For the matching fitting, the lower part of the other side of the fixing sticker is provided with a groove that runs through the inner ring and the outer ring. The groove makes the fitting part form a gap, and the fixing structure of the fixing ring presses the side of the liquid-receiving bag facing the abdomen into the fitting Finally, the fixing structure of the fixing ring is fixed with the matching parts; the upper part of the fixing sticker is formed with a truncation opening, which cuts off the upper part of the fixing sticker, and an intelligent alarm device is arranged on the liquid contact bag, which includes a liquid level sensor, a control The chip, the alarm and the battery, the liquid level sensor is connected with the control chip, the control chip is connected with the alarm, and the battery is connected with the control chip and the alarm and supplies power to both.

In order to optimize the above technical solutions, the specific measures taken also include:

The number of the above-mentioned fixing rings is three, correspondingly, there are also three types of fixing stickers, and these three types match the sizes of the corresponding fixing rings respectively.

The order of the outer diameters of the above three types of fixing stickers from small to large is the first fixing sticker, the second fixing sticker and the third fixing sticker. The outer diameter of the first fixing sticker is not larger than the inner diameter of the second fixing sticker, and the second The outer diameter of the fixing sticker is not larger than the inner diameter of the third fixing sticker.

The fixing structure of the above-mentioned fixing ring is a threaded body, and the matching part is a metal seat provided with threads, and the fixing ring can rotate relative to the liquid-receiving bag.

The width of the above-mentioned cut-off opening is greater than the diameter of the liquid contact opening.

The position where the above-mentioned drainage tube passes through the bag body of the liquid-receiving bag is inside the annular diversion wall.

The lower end of the liquid-receiving bag is provided with a liquid outlet, the liquid outlet is plugged with a plug, and the outer end of the plug is not higher than the liquid outlet.

The above-mentioned one-way valve includes four fan-shaped valve pieces, the arc-shaped parts of the valve pieces are fixed on the annular flow guide wall, and the pointed parts face each other and bend toward the lower part of the liquid-receiving bag.

The peritoneal fluid drainage device of the present invention has the following advantages:

1. There is a ring-shaped diversion wall inside the liquid-receiving bag. The ring-shaped diversion wall cooperates with the two sides of the liquid-receiving bag to separate the space in the liquid-receiving bag into two parts that are mutually sealed. The lower part of the ring-shaped diversion wall is provided with a one-way valve. , the one-way valve allows the liquid to flow from the liquid-receiving port to the lower part of the liquid-receiving bag, and vice versa. When it reaches the liquid-receiving bag, the seepage below the liquid-receiving bag cannot return to the liquid-receiving port through the one-way valve, which effectively prevents the return of the seepage.

2. Although the liquid-receiving bag of the present invention is sealed at the peritoneal stoma, compared with the prior art, the main force for fixing the liquid-receiving bag is not at the liquid-receiving port: the present invention uses the fixing ring and the fixing sticker The phase fixation transfers the main force of fixing the fluid bag to the fixation sticker. The advantage of this setting is that it can greatly reduce the connection strength between the liquid contact port and the skin, so that the skin at the liquid contact port will not be subjected to great tension and pressure, and relieve the discomfort caused by the long-term pressure on the skin at the wound site of the patient.

3. The present invention has a plurality of fixing rings and fixing stickers of different sizes. When in use, a fixing sticker of a size is selected to stick on the patient's abdomen, and then the fixing ring and the fixing sticker are connected together. After a period of time, the connection between the fixing ring and the fixing sticker can be released, then the fixing sticker can be torn off, and a fixing sticker of a different size can be pasted on the skin, and then the corresponding fixing ring can be connected and fixed with the fixing sticker. There is no overlapping part of the skin fixed by the fixed patch after replacement and the fixed patch before replacement. By replacing the fixed stickers, the excessive pressure on the skin at the same position can be reduced, and the discomfort of the compressed skin can be greatly relieved.

4. The present invention is equipped with an intelligent alarm device. When the exudate in the drainage bag is higher than a certain height, the alarm device will alarm to remind the nursing staff to drain in time.

5. The liquid outlet plug cover of the present invention adopts an embedded design to avoid protruding and damaging the skin.
