Description

urinary catheter

technical field

The utility model relates to a urinary catheterization device.

Background technique

Clinically, indwelling catheterization is often used clinically when patients cannot get up to urinate by themselves due to various reasons such as urinary retention, postoperative immobilization, coma, inconvenient movement, and long-term bed rest. However, in the few days before inserting the catheter, the incomplete fit between the catheter balloon and the skin in the urethra may cause urine to leak out along the catheter, thereby increasing the difficulty of nursing; Or grabbing and pulling out the catheter when unconscious, can lead to urethral injury and infection, and also increase the workload of medical staff; secondly, long-term catheterization increases the risk of urinary tract infection in patients.

Urinary catcher is an external catheter device for the convenience of urination for the above-mentioned people in need, and has the following advantages: 1. It can catch urine in multiple positions such as lying on the side or lying on the back; 2. Breathable, comfortable, and flexible to adjust; 3. Avoid repeated urination Quilt, reduce the burden of care, easy to use, simple operation. However, the urinal is not suitable for patients with urinary retention and need to keep urine culture samples.

Utility model content

In view of this, the technical problem to be solved by the utility model is to provide a urinary catheter urinal.

The urinary catheter urinal of the present utility model includes a catheter, the upper end of the catheter is inserted into the bladder through the urethra, and a urinal located outside the human body, the urinal includes a urine funnel and is detachable. The drainage tube connected to the lower part of the urine-receiving funnel and the wearing part connected to the urine-receiving funnel, the top of the urine-receiving funnel has an everted skirt, and the urine-receiving funnel is worn on the lower body of the human body through the wearing part. The skirt wraps the outlet of the human urethra and is in contact with the skin of the human body. The lower end of the urinary catheter is inserted into the urinary funnel and axially overlaps with the upper part of the drainage tube. connected buckle.

Further, a negative pressure drainage bag is connected to the lower end of the drainage tube, and a urine release switch is arranged below the negative pressure drainage bag.

Further, the wearing part is an underwear-type waist fixing belt.

Further, the lower part of the drainage tube is provided with a switch clip that can open and close the drainage tube.

The beneficial effects of the utility model:

1. The combination of internal catheterization and external catheterization can prevent urine leakage during catheterization after use, reduce the number of nursing care, and also keep the perineum clean and reduce the chance of urinary tract infection.

2. It can prevent patients from urethral damage caused by self-grabbing and pulling out the catheter after catheterization.

3. The urine bag uses a vacuum negative pressure device to prevent urine backflow caused by various reasons and reduce the chance of urinary tract infection.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is the structural representation of the utility model.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings, as shown in the figure: the urinary catheter urinal of the present embodiment includes a catheter 1, and the upper end of the catheter 1 is inserted into the bladder through the urethra, and also includes a catheter located outside the human body. The urine receiver 2 includes a urine receiver 21, a drainage tube 22 detachably connected below the urine receiver 21, and a wearing part 23 connected to the urine receiver 21. The urine receiver The top of the funnel 21 has an everted skirt 24. The urine-receiving funnel 21 is worn on the lower body of the human body through the wearing part 23. The skirt 24 wraps the urethral outlet of the human body and contacts the skin of the human body. The urinary catheter 1 The lower end of the catheter is inserted into the urine funnel 21 and axially overlaps with the upper part of the drainage tube 22, and the bottom of the urine funnel 21 is provided with a buckle 25 for clamping the lower end of the catheter 1. The specific shape of the urine-connecting funnel 21 will conform to the ergonomics of men or women, and men and women are different. This structure is a combination of internal and external catheterization. The urinary catheter 1 is an internal catheterization structure, and the urine receiver 2 is an external catheterization structure. In this way, the urinary catheter 1 has no exposed part, and the patient cannot touch the urinary catheter 1, so that the urinary catheter 1 will not be inserted or removed due to misoperation, and the urine-connecting funnel fully covers the perineum or penis to protect the perineum Clean and reduce discomfort for patients. The urinary catheter 1 and the drainage tube 22 form an inner and outer tube structure. Urine enters the outer tube, the drainage tube 22, after passing through the inner tube, the urinary catheter 1, and is exported through the drainage tube 22. Because the axial direction of the urinary catheter 1 and the drainage tube 22 The parts overlap, so that the urine directly enters the drainage tube 22 after coming out from the catheter 1, and the urine will not pollute the urine receiving funnel 21, and the urine receiving funnel 21 can be reused, and the drainage tube 22 can only be replaced when needed. The buckle 25 can fix the lower end of the urinary catheter 1 on the inner bottom of the urine receiving funnel, avoiding the catheter from directly hanging in the air in the urine receiving funnel 21 and causing shaking, and then rubbing against the patient's skin to cause discomfort to the patient.

As a further improvement of the above technical solution, a negative pressure drainage bag 3 is connected to the lower end of the drainage tube 22 , and a urine release switch 4 is provided below the negative pressure drainage bag 3 . Negative pressure drainage bag 3 prevents urine from flowing back, reduces the chance of infection, reduces the frequency of catheter replacement, reduces the difficulty of nursing care for medical staff and family members, and saves medical resources and hospitalization costs for patients. When the urine in negative pressure drainage bag 3 Open the urination switch 4 to urinate after the fluid is full.

As a further improvement of the above technical solution, the wearing part 23 is an underpants type waist fixing belt, which is convenient for wearing.

As a further improvement of the above technical solution, the lower part of the drainage tube 22 is provided with a switch clip 5 that can open and close the drainage tube 22 . Switch clip 5 is used to control whether the patient urinates. For example, the patient needs to be trained to urinate voluntarily before pulling out the catheter. It can be stored in the bladder, and when the patient feels urination such as bloated urine, the switch clip 5 is opened, and the urine will automatically flow out in the drainage bag.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions without departing from the spirit and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
