Description

A sterile bladder irrigator

technical field

The invention relates to a medical tool, in particular to a sterile bladder irrigator.

Background technique

Clinically, it has become a routine treatment to perform bladder irrigation for patients with continuous catheterization to prevent urinary tract infection. The conventional bladder irrigation method is to use a syringe to inject the solution into the urinary catheter, pour the solution into the bladder through the catheter, and then use the siphon principle to drain the injected liquid to achieve the effect of bladder irrigation.

The existing bladder flushing method is to send the solution into the bladder through a urinary catheter, and after staying for a period of time, disconnect the infusion tube for delivering the solution from the urinary catheter, connect the urinary catheter with a drainage tube or a urine bag, and release the solution It is exported for the purpose of flushing the bladder, but the connection between the catheter and the drainage tube is unreliable during the operation, and it is easy to detach, causing bacteria to easily enter the patient's bladder from the catheter. The operation process is very unhygienic, and the patient's postoperative resistance is common. Low, which may lead to postoperative infection of the patient and affect the recovery of the patient.

The catheter, infusion tube and drainage tube are all connected to the three interfaces of the three-way valve through screw caps. The infusion tube is used to send the flushing solution from the infusion bottle to the three-way valve. The tube is used to send the irrigation solution from the tee into the human bladder or to take the liquid in the bladder out of the body, and the drainage tube is used to drain the solution from the urinary catheter.

Preferably, a pressure sensor for measuring pressure is installed on the urinary catheter.

Preferably, the infusion tube is equipped with an incubator for keeping the flushing solution warm.

Preferably, the heat preservation box is a cavity structure, the infusion bottle is placed in the cavity, the inner wall and the outer wall of the heat preservation box cavity are provided with an insulating layer, and an insulating layer is arranged between the inner wall and the outer wall, and the insulating layer is a resistance wire Weaving mesh structure, resistance wire and wire connection.

Preferably, the shape of the cavity of the heat preservation box coincides with the outer shape of the infusion bottle.

Preferably, a urine bag is connected to the end of the drainage tube.

Preferably, the catheter, infusion tube and drainage tube adopt medical silicone tube or PU tube.

The sterile bladder irrigator of the present invention uses a medical three-way valve to connect the catheter, infusion tube, and drainage tube to the three interfaces of the three-way valve respectively. During operation, the three-way valve is used to control the communication between different catheters. The catheter and catheter lead the solution into the human bladder. After staying in the human body for a period of time, the three-way valve is rotated to make the catheter and drainage tube conduct, and the solution is exported from the bladder through the catheter and drainage tube to realize the function of flushing the bladder. Purpose: The urinary catheter, infusion tube and drainage tube are all connected to the three interfaces of the three-way valve through screw caps to ensure good sealing performance. The solution has no contact with the outside world during the entire operation process, realizing aseptic operation and avoiding human body Fungal infection, and the catheter, infusion tube, and drainage tube are reliably connected to the tee, so there will be no problem of pipe falling off, ensuring the cleanness of the flushing solution, no risk of fungal infection, and safer and more reliable use.

Further, a pressure sensor for measuring pressure is installed on the catheter to monitor the pressure of the catheter in real time, so as to avoid excessive pressure of the delivered solution, which may cause discomfort or other pathological changes to the human body.

Furthermore, the infusion tube is equipped with an insulated box for keeping the flushing solution warm, and the solution in the infusion bottle is heated and kept warm to prevent the solution temperature from being too low, which may cause discomfort or other reactions after entering the human body and affect the therapeutic effect.
