Description

A female external urine collector

technical field

The utility model relates to the field of medical equipment, in particular to an external urine collector suitable for hospital patients, the elderly and special environments.

Background technique

Clinically, for patients who need immobilization after surgery, urinary catheters are often used to drain urine. However, long-term indwelling catheters may lead to the risk of retrograde infection of the urinary system. Especially in some female patients, due to the relaxation of urethral smooth muscle, it is easy to cause urine leakage during indwelling catheter. At the same time, urethral injury, difficulty in pulling out catheter, and possible urinary retention after catheter removal may also occur. At present, there are few external urination tools suitable for female patients clinically, and bedpans and various self-made simple urine collectors, urine pads and diapers are mainly used. There are many disadvantages in various methods: firstly, the use of the bedpan requires the patient to raise the buttocks, which brings a lot of pain to surgical patients and bedridden patients such as the elderly, weak, and obese, and requires the assistance of the caregiver, which cannot be completed by oneself; Most of the women's urine collectors provided on the website are wide-mouth type. This type of urine collector can be used standing up, but due to the physiological characteristics of the short and thick female urethra, the wide-mouth design cannot be completely close to the skin when lying in bed. Liquid is easy to stay along the skin, contaminating the sheets and skin, causing skin maceration and damage. At the same time, changing clothes and bedding also brings great inconvenience to nursing staff; Skin pressure sores, urine samples for examination are difficult to collect.

Utility model content

Aiming at the defects in the prior art, the purpose of this utility model is to provide an external urine collector suitable for women, especially when the movement is inconvenient under postoperative braking state, which can be conveniently used.

Angle a, and a smooth transition, ensure that it is close to the physiological curvature of women, so that all the urine is received into the diversion inlet of the urine collector without dripping. And the rounded arc design will not scratch the female vaginal opening, and there will be no discomfort during use.

(2) The utility model is designed with a concave arc-shaped handle, which is convenient to hold. In addition, the design of the weight-reducing inner groove reduces the manufacturing cost of the product and also reduces the weight. The user can use it conveniently without the assistance of the nursing staff. .

(3) The diversion outlet designed by the utility model has a tapered structure on the outside and a trumpet opening structure on the inside. The internal horn-shaped opening structure can be matched with the front end of a conventional medical urine collection bag, and the external conical structure can be connected to the urine collection device through a pipe, which can be used in special outdoor environments and has high universality.

Detailed ways

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

Referring to Fig. 1 and Fig. 2, the utility model provides a female external urine collector, which includes a urinary catheter and a urine collector, wherein the catheter includes a diversion inlet 1, a diversion outlet 2 and a handle 6. As shown in FIG. 4 , the diversion inlet 1 is provided with an upper arc-shaped protrusion 3 and a lower arc-shaped protrusion 4 matching the physiological curvature of the female genitals. The urine collector is different from the existing wide-mouth urine collector. When urinating, the urine collector is placed inside the labia majora, and the upper and lower arc-shaped protrusions are close to the wall of the vaginal opening. The arc-shaped protrusion is placed in the vestibule of the vagina, and the lower arc-shaped protrusion is close to the vaginal opening.

Referring to Figure 3, the direction of the axis from the diversion inlet 1 to the diversion outlet 2 is the Z direction, and the outer ends of the upper arc-shaped protrusion 3 and the lower arc-shaped protrusion 4 respectively form a certain angle a with the Z direction, and the angle a As the direction away from the diversion inlet 1 gradually decreases, the angle a is between 10° and 60°, and the transition is smooth, so as to ensure that it is close to the female physiological curvature, so that all the urine is received into the diversion inlet of the urine collector. No drips even when lying down. And the rounded arc design will not scratch the female vaginal opening, and there will be no discomfort during use.

Both the upper arc-shaped protrusion 3 and the lower arc-shaped protrusion 4 are made of non-toxic skin-friendly materials, and the skin-friendly materials include non-toxic silica gel and plastic materials, among which silica gel is preferred, which is safe and non-toxic. The external catheterization device can effectively avoid damage to the urethra caused by the indwelling catheter, and eliminate hidden dangers of sequelae of the indwelling catheter, such as leakage of urine, urinary retention, and urinary system infection.

Referring to Fig. 4, an upper diversion wall 8 and a lower diversion wall 5 are arranged between the diversion inlet 1 and the diversion outlet 2, and when the urine collector is used in a lying state, the upper diversion wall 8 is The funnel structure can direct the urine to the direction of the diversion outlet 2, and the lower diversion wall 5 is designed as a reverse funnel structure to avoid backflow of urine.

Referring to Fig. 1 and Fig. 2, the handle 6 of the urinary catheterization device for female external use is in a concave arc shape, which is convenient to hold during use. In addition, as shown in Figure 4, the handle is provided with a weight-reducing inner groove 7 near the position of the guide tube 5. Through the weight-reducing design, the product manufacturing cost is also reduced, and the product weight is also reduced, which is convenient for the user to operate without the assistance of other personnel. Next, use it yourself.

As shown in FIG. 4 , the diversion outlet 2 has a tapered structure on the outside and a trumpet opening structure on the inside. The internal horn-shaped opening structure can be matched with the front end of a conventional medical urine collection bag, and the external conical structure can be connected to the urine collection device through a pipe, which can be used in special outdoor environments and has high universality. After the urine is collected in the urine bag, it can be used for detection and testing, or it can be disassembled for further processing, and the catheterization device can continue to be used after simple cleaning.

The utility model is not limited to the above-mentioned embodiments. For those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made. within the scope of the new protection. The content not described in detail in this specification belongs to the prior art known to those skilled in the art.
