Description

Technical Field

[0001] The utility model belongs to the field of urinary catheters, and specifically relates to a disposable super-slippery silicone rubber urinary catheter. Background Art

[0002] A silicone rubber urinary catheter is a medical device used to insert into the urethra to assist in urination or drain urine, and is usually used in hospitals and clinical medical environments. Clinically, after collecting the patient's urine, urine tests will be performed to judge the patient's physical condition.

[0003] The existing Chinese patent with the publication number CN211024711U discloses a painless urinary catheter, which includes a urine drainage channel, a water injection channel, a water sac, a drug injection channel, a drug sac and a drug drainage channel located in the urinary catheter. The water sac is located outside the urine drainage channel, and the drug sac is arranged outside the water sac. The water injection channel and the drug injection channel are formed in the catheter wall. The urinary catheter has a water injection port, a drug injection port and a drug drainage port. The drug drainage port is opened on the catheter wall. The water sac is connected to the water injection port through the water injection channel, the drug sac is connected to the drug injection port through the drug injection channel, and the drug sac is also connected to the drug drainage port through the drug drainage channel. After injection of water, the expansion of the water sac makes the front section of the urinary catheter larger so that the urinary catheter is fixed in the urethra, and the expansion of the water sac applies pressure to the drug sac outside the water sac, so that the anesthetic drug in the drug sac is discharged into the urethra through the drug drainage channel and the drug drainage port. The utility model can improve the comfort of indwelling urinary catheters, reduce related complications, and reduce or prevent the occurrence of catheter dislodgment events.

[0004] In view of the above related technologies, the purpose of helping patients urinate can be achieved. However, when the urinary catheter is in use, it is usually used in cooperation with a urine bag. The urine in the patient's body can enter the urine bag from the urinary catheter. When the urine flows, it is inconvenient to take a urine sample, and the urine bag needs to be separated from the urinary catheter to take out the urine, which is more inconvenient to operate and affects the subsequent urine test of the patient.

[0005] Therefore, we propose a disposable super-slippery silicone rubber urinary catheter to solve the problems raised above. Content of the Utility Model

[0006] Aiming at the above problems existing in the prior art, the purpose of the present utility model is to provide a disposable super-slippery silicone rubber urinary catheter.

One side of the branch pipe structure is connected to a urine bag structure for storing urine. The end of the urine bag structure far from the branch pipe structure is connected to a shunt pipe. The other end of the shunt pipe is hermetically installed with a sampling bag, and a water stop member is disposed on the outer side of the shunt pipe. Through the water stop member, the internal flow channel of the shunt pipe can be controlled, so that the urine in the urine bag structure enters the sampling bag through the shunt pipe, realizing the sampling of urine.

[0008] Preferably, the tip of the catheter structure is evenly distributed with catheterization holes, and a super-lubricating coating is disposed on the outer side of the tip of the catheter structure to play a lubricating role. A coating portion is also disposed on the outer wall of the catheter structure.

[0009] Preferably, the coating portion includes a hydrophilic coating and an antibacterial coating sequentially disposed on the outer wall of the catheterization holes, and the antibacterial coating plays an antibacterial role.

[0010] Preferably, an adapter pipe is disposed on the side of the urine bag structure close to the branch pipe structure, and the branch pipe structure and the urine bag structure can be connected through the adapter pipe.

[0011] Preferably, a sealing ring and a mounting ring are disposed on the side of the sampling bag close to the shunt pipe, and the sealing ring is placed inside the mounting ring. The sealing ring can be inserted into the shunt pipe. Bolts are disposed on the outer side of the mounting ring. Through the bolts, the mounting ring can be fixed, and the sealing ring is used for sealing to avoid leakage.

[0012] Preferably, the water stop member includes a mounting frame disposed on one side of the urine bag structure and a support rod disposed inside the mounting frame. A threaded rod is inserted through the surface of the mounting frame, and one end of the threaded rod is connected to a water stop plate. Rotating the threaded rod can make the water stop plate approach the shunt pipe and extrude the shunt pipe, controlling the flow of urine.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The present utility model can collect urine through the disposed urine bag structure, shunt pipe, sampling bag and water stop member, and then through the water stop structure, the urine can flow from the shunt pipe into the sampling bag, so that urine can be sampled, which is beneficial for urine tests, with simple operation and high practicality.

[0015] The present utility model can hermetically connect the sampling bag and the shunt pipe through the disposed sealing ring, mounting ring and bolts, thus avoiding urine leakage and being convenient to use. Description of the Drawings
