Description

The present application relates to long-term care products, particularly urine collecting devices.

Urinary incontinence in the elderly, disabled people, and postoperative patients generally use the simplest urine collection bag, take advantage of the difference in fluid level via a urinary catheter, and use gravity to collect urine. Realizes collection in bags. The disadvantage is that if the tube path is not placed from high to low, it cannot be used normally, and urine does not flow into the urine collection bag but leaks out, contaminating the bedding. There are a huge number of older people in China, but most of them have no disability or incontinence and are only unable to walk. Symptoms such as frequent urination, urgency of urine, and pseudourinary incontinence appear due to deterioration of physical function, and especially when resting at night, many times you wake up and go to the bathroom, you fall and get injured, and the quality of sleep is poor. There is a risk of accidents and additional labor, such as the need for caregivers. In addition, people who are resting in bed for a short period of time after surgery and persons with physical disabilities also face the above-mentioned problems of urination, so there is a need for a urine collection system that can be used while lying on the bed. There are already urine collectors that collect urine by electric negative pressure suction, but these urine collectors have a complicated overall structure, the main body and tank are separated, and they are generally placed on the left and right. It requires a negative pressure tube that is detachably connected between the two, and the route is complicated. In addition, urine tends to remain in the tube, and the detachable connection has poor sealing performance, which reduces reliability.

NS. Since it is not necessary to turn the collection tank upside down and discard the urine by hand, the caregiver basically does not get his hands dirty with urine.

As the power unit of the main body, a diaphragm vacuum pump having a high negative pressure and a small flow rate may be adopted. Since the power consumption is relatively low, the control circuit, battery, display control interface, muffling filtration system, etc. are all integrated in the main body, the volume of the entire device is very small, it is supplied independently internally, and it is a commercial power supply. There is no need to use. It has a wide range of applications, and can be used arbitrarily in equipment such as senior cars, patient transfer cars, and mobile nursing beds, and is not restricted by power supply. The flow rate of the diaphragm pump of the negative pressure power unit can be between 12 and 16 L / min, the negative pressure can reach -85 KPa, driven by a DC motor (brushed / brushless), and the output is 25 W. It is as follows. The urine collection head adopts a structure in which the center is a conductive probe (second electrode) and the periphery is a stainless steel outer tube (first electrode), and the probe is arranged in the center of the tubular stainless steel outer tube. Therefore, when it comes into contact with urine, it can be triggered by the shortest route and is extremely sensitive. In the absence of urine, the longest pathway is retained, and even if there is a water film on the surface, it does not trigger the sensing circuit, greatly reducing the probability of malfunction. In addition, the stainless steel outer tube is easy to process and manufacture, the surface is not easily corroded, it is easy to clean, and the growth of bacteria is reduced.

Since the urine collection system uses internal power supply, the entire device can be moved to the toilet, and when cleaning, the position of the urine collection cup is aligned with the faucet, and water is injected to automatically activate negative pressure suction. A stream of water passes through all parts of the tube (including the inside of the body) that are contaminated with urine and reaches the inside of the collection tank. Cleaning is completed simply by shaking the main body, and finally the sewage is discharged to the toilet bowl from the discharge port. Not only is this cleaning method highly efficient, it is clean and hygienic as the caregiver does not get dirty with urine. When used at night, the urine collection system is generally placed beside the bed, but it is convenient to take by providing a breathing light on the urine collection cup to indicate its position, and a switch on the head. The LED light can be controlled to provide the user with soft light lighting as needed so that the product can be operated by oneself. Therefore, elderly and weak people do not have to spend time and effort to turn on the interior lights, which reduces the difficulty of operation, avoids affecting the rest of others, and is compassionate. It has a certain design.
