Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable sterile urinary catheter. Background Art

[0002] A urinary catheter is a tube that is inserted from the urethra into the bladder to drain urine. It is mainly made of natural rubber, silicone rubber or polyvinyl chloride (PVC). After the catheter is inserted into the bladder, there is an air 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] In actual use, since the material of the catheter is relatively soft, it is easy to bend when inserted into the bladder through the urethra, making it inconvenient to adjust the direction and requiring multiple reinsertions, making the operation more complicated. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a disposable sterile urinary catheter, which can ensure that the urinary catheter is smoothly inserted into the bladder and improve work efficiency.

[0005] In order to solve the above technical problems, the technical solutions adopted by the present utility model are as follows.

[0006] A disposable sterile urinary catheter comprises a drainage tube, a water injection tube and a flushing tube, wherein the water injection tube and the flushing tube are independently arranged between the inner and outer tube walls of the drainage tube; an air bag is arranged at the front end of the drainage tube, which clamps the urinary catheter in the bladder after being expanded by water injection; a drainage port is arranged at the front end of the drainage tube for draining urine in the bladder; a guide wire is installed in the drainage tube to enhance the hardness of the urinary catheter and facilitate insertion into the bladder; the front end of the water injection tube is closed and located at the rear end of the drainage port; a water injection port connected to the air bag is arranged on the water injection tube; a one-way valve for injecting water into the water injection tube is arranged at the rear end of the water injection tube; the flushing tube is arranged through the front end of the drainage tube, and the flushing port at the front end of the flushing tube is inserted into the bladder along with the head of the urinary catheter; a cap is installed at the rear end of the flushing tube to maintain a sterile environment inside the flushing tube.

[0007] The disposable sterile urinary catheter has a connector at the tail end of the flushing tube which is connected to the cap and ensures sealing.

[0008] The disposable sterile urinary catheter has a developing line axially penetrating the interior of the drainage tube for easy observation.

[0009] Due to the adoption of the above technical scheme, the technical progress achieved by the present invention is as follows.

[0010] The utility model provides a disposable sterile urinary catheter, which has a certain hardness through a guide wire inserted into a drainage tube, greatly facilitates the insertion of the urinary catheter into the bladder, avoids the need for multiple insertions due to the softness of the urinary catheter body, and improves work efficiency.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0017] Disposable sterile urinary catheter, such as Figures 1 to 4 As shown, it includes a drainage tube 1, a water injection tube 2, and a flushing tube 3. The water injection tube 2 and the flushing tube 3 are independently arranged between the inner and outer tube walls of the drainage tube 1, and an air bag 4 is arranged at the front end of the drainage tube 1.

[0018] A drainage port 5 for draining urine from the bladder is provided at the front end of the drainage tube 1 , and a developing line for easy observation is axially penetrated inside the drainage tube 1 .

[0019] A guide wire 8 is installed in the drainage tube 1 , and the front end of the guide wire 8 is set to be hemispherical. The diameter of the ball head is larger than the maximum size of the drainage port, which can prevent the front end of the guide wire 8 from passing through the drainage port 5 .

[0020] The guide wire 8 can make the drainage tube have a certain hardness, which is convenient for inserting the urinary catheter into the bladder.

[0021] The front end of the water injection pipe 2 is closed and is not arranged beyond the drainage port 5 , and a water injection port 11 connected to the airbag 4 is opened on the water injection pipe 2 .

[0022] A one-way valve 9 is provided at the tail end of the water injection pipe 2. Water is injected into the water injection pipe 2 through the one-way valve 9 and enters the airbag 4 through the water injection port 11, so that the airbag 4 is filled with water and expanded, which can prevent the urinary catheter entering the bladder from slipping out.

[0023] A connector 10 is installed at the tail end of the flushing tube 3 , and the connector 10 is assembled and connected with the cap 6 , which can ensure that the internal environment of the flushing tube 4 is in a sterile state.

[0024] The front end of the flushing tube 3 passes through the drainage tube 1, and the flushing liquid enters the flushing tube 3 and then enters the bladder through the front flushing port 7 for cleaning.

[0025] The usage of the utility model is:

[0026] First, the guide wire 8 is inserted into the drainage tube 1 to make the drainage tube 1 have a certain hardness, so as to facilitate insertion into the urethra and then into the bladder.

[0027] Next, the guide wire 8 is pulled out, and water is injected into the water injection pipe 2 through the one-way valve 9, so that the air bag 4 is inflated with water to clamp the front end of the urinary catheter to prevent the urinary catheter from slipping out.

[0028] Finally, the urine in the bladder is discharged into the drainage bag through the drainage port 5 and the drainage tube 1.

[0029] When the bladder needs to be cleaned, the cap 6 at the rear end of the flushing tube 3 is opened to allow physiological saline to enter the bladder from the flushing tube 3 for cleaning, and the cleaned liquid enters the drainage tube 1 along the drainage port 5 and is discharged.

[0030] The utility model provides a disposable sterile urinary catheter, which has a certain hardness through a guide wire inserted into a drainage tube, greatly facilitates the insertion of the urinary catheter into the bladder, avoids the need for multiple insertions due to the softness of the urinary catheter body, and improves work efficiency.
