technical field

The utility model relates to a medical device, in particular to a multifunctional catheter for bladder patients which integrates flushing, medicine injection and catheterization, in particular a new three-chamber catheter for bladder flushing and medicine Prime the connector.

Background technique

As we all know, bladder flushing is a commonly used nursing operation in clinical practice. It is a flushing method that injects diluted medicinal solution or normal saline through a catheter (usually a double-lumen structure) into the patient's bladder once or continuously, and performs drug treatment inside it. . At present, the new three-chamber urinary catheter bladder irrigation and drug infusion connector used for bladder irrigation does not have a matching connector, so it can only be connected with a disposable blood transfusion set or other methods. The disadvantages are: 1. After repeated flushing operations, the mouth and neck of the urinary catheter flushing cavity will be loosened, resulting in improper connection and leakage of urine. 2. During the flushing operation, the mouth of the flushing cavity should be connected with an infusion set or a blood transfusion set, but it is often not plugged in place due to lack of matching. When the patient turns over and shifts during flushing, the connecting part will easily fall off, and the urine will flow out and it will not be easy. observed. 3. Increase unnecessary pain and economic burden on patients. 4. During the operation of clinical medical staff, it is easy to come into contact with the patient's urine during repeated flushing, connection, and blockage. 5. It increases the operational difficulty of medical personnel. Therefore, it is necessary to change the time.

The beneficial effects of the utility model:

The utility model is equipped with a three-way joint on the original liquid injection port, which can prevent the catheter from falling off, urinating and retrograde infection of the urinary tract, and can realize the small volume after installation and facilitate indwelling. After the infusion set is connected and flushed, it can be pulled out directly. The self-closing device has the advantages of simple structure and convenient use, can reduce patients' unnecessary pain and economic burden, and protect medical workers.

The utility model can also detect blood in the patient's urine in time, so as to facilitate timely injection and treatment.

The utility model further improves the functions of the existing novel three-chamber urinary catheter bladder flushing and drug infusion connector, makes it more convenient to use as a whole, reduces infection of patients, and prevents pollution of the treatment environment.
