Description

Multifunctional external connector of three-cavity catheter flushing interface

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a three chamber catheters wash multi-functional outer joint of interface.

Background

In the medical field, patients who leave urinary catheters for a long time often suffer from turbid, precipitated or crystallized urine drainage, which can lead to blockage of the urinary catheter. Bladder irrigation is an important means for keeping the urine drainage of patients with indwelling catheters unobstructed clinically, and can prevent infection.

The clinical practice is to place a sterile three-cavity catheter for bladder irrigation. When the bladder is flushed, the aseptic operation technology is strictly controlled, the flushing fluid is connected with the flushing conical connector end, and the flushing fluid enters the bladder and is drained out of the body through the drainage conical connector end. During the flushing interval, the flushing cone-shaped mouthpiece end should keep the system closed to prevent secondary infection from coming into contact with the outside. At present, the manual assembly and connection of the flushing device by nursing staff is required in clinic. During installation, on one hand, the interface is not firmly connected, so that washing liquid leakage is easy to occur, and the skin of a patient is wet, so that the risk of skin injury is increased; on the other hand, the interface is easy to be polluted when the catheter is manually assembled, and the risk of exogenous infection of the catheter is increased.

In addition, there is a clinical need to detect intra-abdominal pressure. Intra-abdominal hypertension (IAH) is an independent risk factor for death of critically ill patients, so the application of intra-abdominal pressure (IAP) monitoring in the diagnosis and treatment of critically ill patients is increasingly gaining importance. Measurement methods of IAP are classified into direct measurement methods and indirect measurement methods. Direct measurements are invasive and not preferred clinically. The transcystic measurement (UBP) among indirect measurements is the method of choice for measuring IAP in clinical work. UBP is divided into a manual measurement method and a pressure sensor measurement method, and a pressure measuring device needs to be manually assembled by nursing staff, so that the problems that an IAP pipeline has bubbles, a joint leaks and the like are easily caused, the pressure measuring result is interfered, and the cost is high.
