Description

Medical urinary catheter

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a medical ureter.

Background

Patients who cannot urinate by themselves due to various reasons generally need to place a urinary catheter to drain urine. The urinary catheter which is commonly used clinically is usually made of silica gel materials, and a certain amount of normal saline is injected into the water sac through the water injection port to fill the water sac and block the internal orifice of the urethra so as to fix the urinary catheter. The current urinary catheter can achieve the purpose of urine drainage, but patients with intracranial lesion or paraplegia frequently exist clinically, particularly old female patients over 60 years old have atrophy and hypodynamia of urethral sphincter, so that the catheter cannot be attached to an inner opening of the urethra, and urine leakage of the urinary catheter is caused. Leakage of urine leads to the perineum skin of the patient to be continuously moist, then causes the skin problem, and the nurse increases the water injection amount in the water sac and still can not solve the leakage of urine problem. Therefore, the problem of urine leakage of patients with ureter becomes a clinical nursing problem.

SUMMERY OF THE UTILITY MODEL

In view of the above problem, the utility model provides a medical ureter, the utility model has the advantages of avoid leaking urine and make skin suffer the urine amazing, reduce the maceration dermatitis incidence, reduce the frequency of changing the nursing pad, the nurse's that significantly reduces work load improves the nursing quality.

The technical scheme of the utility model is that:

the utility model provides a medical ureter, including pipeline, water pocket and ring film, the inner ring of ring film with the department of going to the bottom of water pocket links to each other, be equipped with the inlet on the port of the one end of pipeline, the last end department of water pocket is close to the inlet, the other end of pipeline is equipped with liquid outlet and water filling port.

The working principle of the scheme is as follows:

under strict aseptic operation, inserting one end of the pipeline provided with the water sac into the urethra, inserting the end of the pipeline into 5-6 cm after urine is seen, injecting a proper amount of normal saline into a water injection port, and slightly pulling the pipeline outwards until resistance is met.

In a further technical scheme, the diameter of the outer ring of the circular ring membrane is larger than that of the water sac.

After the water bag is filled with water, the circular ring film positioned at the lower bottom of the water bag is unfolded along with the water filling of the water bag, the diameter of the circular ring film is larger than that of the water bag, and the circular ring film can effectively block the inner opening of the urethra to avoid urine leakage.

In a further technical scheme, two channels are arranged in the pipeline, two ends of one channel are respectively connected with the liquid inlet and the liquid outlet, and two ends of the other channel are respectively connected with the water bag and the water injection port.

Set up two passageways, on the one hand can avoid the bacterium to get into from the water filling port and infect the bladder, on the other hand water entering bladder when preventing the water injection.

In a further technical scheme, a one-way valve is arranged in the water filling port.

The check valve can effectively simplify the water injection flow and has better sealing property during water injection.

The utility model has the advantages that:

1. the nursing pad has the advantages of avoiding urine leakage to cause skin to be stimulated by urine, reducing incidence rate of maceration dermatitis, reducing frequency of replacing nursing pads, greatly reducing workload of nurses and improving nursing quality.

2. After the water bag is filled with water, the circular ring film positioned at the lower bottom of the water bag is unfolded along with the water filling of the water bag, the diameter of the circular ring film is larger than that of the water bag, and the circular ring film can effectively block the inner opening of the urethra to avoid urine leakage.

3. Set up two passageways, on the one hand can avoid the bacterium to get into from the water filling port and infect the bladder, on the other hand water entering bladder when preventing the water injection.

4. The check valve can effectively simplify the water injection flow and has better sealing property during water injection.

Drawings

Fig. 1 is a schematic structural diagram of a medical urinary catheter according to the present embodiment.

Description of reference numerals:

1. a one-way valve; 2. a water injection port; 3. a pipeline; 4. a water bladder; 5. a liquid inlet; 6. a circular ring film; 7. and a liquid outlet.

Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

Example (b):

as shown in fig. 1, the medical ureter comprises a pipeline 3, a water bag 4 and a circular ring film 6, wherein an inner ring of the circular ring film 6 is connected with the lower bottom of the water bag 4, a liquid inlet 5 is arranged at a port at one end of the pipeline 3, the upper bottom of the water bag 4 is close to the liquid inlet 5, and a liquid outlet 7 and a water injection port 2 are arranged at the other end of the pipeline.

The working principle of the technical scheme is as follows:

under strict aseptic operation, the end of the pipeline 3 provided with the water sac 4 is inserted into the urethra, 5cm-6cm is inserted after urine is seen, a proper amount of normal saline is injected into the water injection port 2, and the pipeline 3 is pulled outwards slightly until resistance is met.

In another embodiment, the diameter of the outer ring of the circular ring membrane 6 is larger than the diameter of the water sac 4.

After the water bag 4 is filled with water, the circular ring film 6 positioned at the lower bottom of the water bag 4 is unfolded along with the water filling of the water bag 4, the diameter of the circular ring film is larger than that of the water bag 4, and the circular ring film can effectively block the inner opening of the urethra to avoid urine leakage.

In another embodiment, two channels are provided in the conduit 3, wherein two ends of one channel are respectively connected to the liquid inlet 5 and the liquid outlet 7, and two ends of the other channel are respectively connected to the water bag 4 and the water filling port 2.

Set up two passageways, can avoid the bacterium to get into from water filling port 2 and infect the bladder on the one hand, on the other hand prevents that water from getting into the bladder when water injection.

In another embodiment, as shown in fig. 1, a one-way valve 1 is provided in the water injection port 2.

The check valve 1 can effectively simplify the water injection flow and has better sealing performance during water injection.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
