Background technique

A urine drainage tube is a tube inserted into the bladder from the urethra to drain urine. It is very commonly used in hospitals, especially in special circumstances such as surgery or postpartum, to drain pus, blood, and liquid accumulated between human tissues or in the body cavity. Lead outside the body to prevent postoperative infection and promote wound healing.

The catheter of the current urine drainage tube is provided with a first lumen, a second lumen and a third lumen that are not connected to each other to realize the three functions of injecting liquid, draining liquid and inflating. In the human body structure, the male urethra is slender, about 18cm long, and the female urethra is thick and short, about 5cm long. The existing three-lumen catheter of the urine drainage tube has a larger diameter, which causes greater pain to the patient when it is inserted into the body through the urethra and during use, especially for male patients.

When injecting medical solution through a urine drainage tube, using a syringe needle to penetrate the injection chamber can easily injure medical staff.

In addition, when the drainage tube needs to be marked, a physical label is attached to the drainage tube, and the paper label is easy to fall off, making it inconvenient for medical staff to register and manage postoperative urine drainage tubes.

Utility model content

In order to solve the above problems, the present utility model provides a miniaturized multi-functional urine drainage tube, which is convenient for medical staff to use when injecting liquids, convenient for registration and management, and at the same time reduces the pain of patients during use.

A liquid chamber is provided in the catheter, and a liquid outlet hole connected to the liquid chamber is provided on the side of the inlet end. The other end of the liquid chamber is connected to the liquid injection pipe. The other end of the liquid injection pipe is provided with a standard interface for the liquid injection pipe; a protective cap is slidably provided on the liquid injection pipe. , can be connected to the standard interface of the liquid injection pipe;

An air injection chamber is provided in the catheter, one end of the air injection chamber is connected with the air bag, and the other end is connected with the air injection pipe. The other end of the air injection pipe is provided with an air injection pipe interface, and the air injection pipe interface is connected with the air injection equipment;

A connecting thread is provided inside the outlet end, and the conduit is connected to one end of the two-way valve through the connecting thread. The other end of the two-way valve is connected to the urine bag connector, and a urine bag is provided on the urine bag connector.

Further, the liquid injection pipe is inclined toward the outlet direction.

Further, the front end of the introduction end is provided with a liquid outlet hole.

Further, the label piece is made of oval-shaped soft silicone material.

Furthermore, the inner diameter of the standard interface of the liquid injection tube is 0.5cm.

The utility model has the following beneficial effects:

(1) The urine drainage tube is improved from the three lumens of the existing technology to two lumens, which reduces the diameter of the catheter and reduces the patient's pain when the miniaturized multifunctional urine drainage tube is inserted through the urethra and used. It is especially convenient for male patients to use; the urine drainage tube has different functions. The standard interface of the injection tube can be directly connected to the syringe without using a syringe needle, which is convenient for injecting medicine. It can also extract urine for urine testing and inject fluid at the same time. A label piece is slidably provided on the conduit between the tube and the air injection tube to facilitate medical staff to add time marks to the multifunctional urine drainage tube, and to facilitate regular replacement of the multifunctional urine drainage tube to avoid infection.

(2) The injection tube is designed to be inclined toward the outlet end of the catheter. After the injection tube is connected to the syringe, the catheter is less likely to come into contact with the body, which increases the patient's comfort. When injecting, the medicine flows directly toward the introduction end, reducing the need for medication. The fluid flows in the direction of the outlet end to prevent the urine existing in the outlet end tube from flowing back into the body and causing infection.
