Description

Technical Field

[0001] The utility model relates to the technical field of urinary catheterization, in particular to an improved water bag urine leakage-proof urinary catheter. Background Art

[0002] A urinary catheter is a tube that is inserted into the bladder through the urethra to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC) and can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is a water bag near the tip of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine.

[0003] At present, the urinary catheter does not have the function of backwashing, or some urinary catheters serve as both catheterization and flushing. This design has the problem of not being cleaned thoroughly, and the urine remaining in the urinary catheter will be flushed back into the bladder or urethra, increasing the chance of infection; or the flushing tube is placed outside the urinary catheter. This design will cause urine leakage when the water bag cannot block the urethra.

[0004] Therefore, in order to correct the above-mentioned defect, we propose a urinary catheter with an improved water bag to prevent urine leakage. Utility Model Content

[0005] The utility model solves the technical problem of providing an improved water bag urine leakage-proof urinary catheter.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an improved water bag to prevent urine leakage catheter, comprising a water bag, a urinary catheter and an injection tube, and also comprising a flushing tube, the urinary catheter passes through the inside of the water bag, the flushing tube is in the urinary catheter, the outlet end of the flushing tube is in the inlet end of the urinary catheter, the inlet end of the flushing tube passes through the side wall of the outlet end of the urinary catheter, the inlet end of the flushing tube is connected to a rubber plug, and the outlet end of the flushing tube is connected to a one-way check valve to prevent urine from flowing out of the flushing tube.

[0007] Preferably, the water bag is in the shape of a water drop after being expanded by injection of liquid.

[0008] Preferably, the outer diameter of the flushing tube is smaller than the inner diameter of the urinary catheter, and the flushing tube is attached to the inner wall of the urinary catheter.

[0009] Preferably, the outlet end of the urinary catheter is connected to a Y-shaped tube, and both outlet ends of the Y-shaped tube are equipped with connectors.

[0010] Preferably, the injection tube is inside the catheter, the inlet end of the injection tube passes through the side wall of the outlet end of the catheter, and the outlet end of the injection tube is exposed from the side wall of the catheter in the water bag, and the inlet end of the injection tube is also connected with a rubber stopper.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the water bag in the urinary catheter is changed into a water drop shape, which can play a better sealing role and better prevent urine leakage; a flushing tube is added to the urinary catheter, so that flushing and catheterization are independent of each other, thereby achieving better flushing; and a one-way check valve is connected to the outlet end of the flushing tube to prevent urine from flowing out of the flushing tube, thereby preventing urine leakage.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The utility model provides a technical solution:

[0018] See also Figure 1-3 An improved water bag urine leakage prevention catheter comprises a water bag 2 in the shape of a water drop, a urinary catheter 1, an injection tube 7 and a flushing tube 6. The water bag 2 in the shape of a water drop can better fit the bladder neck position, improve comfort and sealing, and prevent urine leakage. The urinary catheter 1 passes through the water bag 2, the flushing tube 6 is in the urinary catheter 1, the outlet end of the flushing tube 6 is in the inlet end of the urinary catheter 1, the inlet end of the flushing tube 6 passes through the side wall of the outlet end of the urinary catheter 1, the inlet end of the flushing tube 6 is connected with a rubber plug, and the flushing tube 6 is connected to the inlet end of the flushing tube 6. The outlet end of the tube 6 is connected to a one-way check valve 8, the outer diameter of the flushing tube 6 is smaller than the inner diameter of the urinary catheter 1, the flushing tube 6 is attached to the inner wall of the urinary catheter 1, the outlet end of the urinary catheter 1 is connected to a Y-shaped tube 4, both outlet ends of the Y-shaped tube 4 are equipped with joints 5, the injection tube 7 is inside the urinary catheter 1, the inlet end of the injection tube 7 passes through the side wall of the outlet end of the urinary catheter 1, and the outlet end of the injection tube 7 is exposed from the side wall of the urinary catheter 1 in the water bag 2, and the inlet end of the injection tube 7 is also connected to a rubber plug.

[0019] Use a syringe to insert a needle (or a silicone buckle, which is opened to connect the syringe nipple or the infusion device nipple) from the rubber plug at the inlet end of the injection tube 7, and inject liquid into the water bag 2 to expand the water bag 2. After the water bag 2 expands, it will appear in the shape of a water drop. The inlet end of the catheter 1 is inserted into the urethra and enters the bladder. The water bag 2 blocks the urethra. The connectors 5 on the two outlet ends of the Y-tube 4 are connected to urine bags.
