Description

A double-tube continuous flushing negative pressure suction tube puncture surrounding exudate collection device

Technical Field

The utility model relates to the technical field of medical devices, in particular to a double-tube continuous flushing negative pressure suction tube puncture surrounding exudate collection device.

Background technique

Infectious pancrealic necrosis (IPN) is a deep soft tissue abscess, also known as pancreatic abscess in the past. It is the main cause of the "second peak of death" in patients with severe acute pancreatitis. At present, with the continuous release of medical evidence, the minimally invasive "step-up" method has become the preferred treatment strategy for IPN. Double-cannula continuous negative pressure irrigation and drainage is the second step of the "step-up" method, and M10 double-cannula continuous negative pressure irrigation and drainage is often used. After 5-7 days, the patient's general condition is evaluated. If the general condition cannot be improved or the condition worsens, the next step is to perform endoscopic debridement of the sinus formed after double-cannula irrigation. After the endoscopic debridement treatment is completed, double-cannula is placed through the sinus again to continue continuous negative pressure irrigation and drainage, or surgical intervention is performed.

In the past two years, nearly 100 cases of pancreatic abscess debridement and external drainage have been performed. According to the principle of step-by-step treatment of pancreatic abscess debridement and drainage, during the treatment process, double cannulas are used for continuous flushing and negative pressure suction to liquefy and dilute some necrotic tissue and remove residual or newly generated necrotic tissue after surgery. The method is that after the double cannulas are inserted, sutures are given at the puncture site to prevent the tube from slipping. However, the pus in the abscess cavity contains a large amount of necrotic products of digestive enzymes. Due to high intra-abdominal pressure and a large amount of liquefied necrotic products, pus often corrodes the skin at the drainage tube mouth. The skin at the suture is also not immune, and the surrounding tissue will be corroded and desuckered. At the same time, more exudate will also significantly increase the incidence of irritant dermatitis around the drainage tube.

For the above existing phenomena, the clinical measures are as follows:

(1) Frequent dressing and clothing changes: Frequent dressing changes will greatly increase the nursing workload, which is not conducive to clinical work. When exudate seeps into gauze dressings, clothes, and bed sheets, the amount of exudate cannot be accurately recorded. When there is a lot of exudate, it is necessary to assist in repeatedly changing wet mattresses, clothes, etc., which makes it impossible for patients to rest at ease, increases psychological burden, and is not conducive to disease recovery.

(2) Use of multiple skin care products: Irritant dermatitis requires multiple dressing changes. In order to prevent severe skin corrosion and reduce direct contact between exudate and skin, more skin protectants are used, which greatly increases the financial burden on patients.

Most of the existing ostomy bags are used for urology and feces collection. If used in this area, it is often necessary to open a window in the ostomy bag, pass the drainage tube through it, and then apply a sterile film on the outside. After using it, the patient is afraid of leakage and dare not move or turn over, and it cannot be guaranteed that the trimming is perfect or leak-free every time. The film will be affected by the exudate and lose its meaning of sticking. Therefore, it is necessary to observe whether there is leakage at all times. This method reduces the time when the exudate is in direct contact with the skin on the basis of changing the dressing, which is not convenient.

Existing patents CN 215900689 U and CN 218515955 U both place the end of the drainage tube in the ostomy bag to achieve vacuum. The double cannula has two layers of inner and outer pipes, and the texture is hard and long. The end of the pipe needs to be connected to a negative pressure suction device, which continuously suctions at a low negative pressure of 0.02-0.04MPa. It is impossible to place the end of the double cannula in the bag to achieve vacuum like the above-mentioned patented technology, and it cannot be used to collect exudate around the puncture site during double cannula flushing.
