Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical assistance, in particular to a clean and closed bedded defecation disposal system. Background Art
[0002] In the current conflicting context of shortage of nursing resources in hospitals and the implementation of the unattended hospitalization model, nursing staff have to take care of both medical care and daily care, and they are unable to do both. For people who cannot take care of themselves due to impaired consciousness, weakness, paralysis, etc., especially critically ill patients in the intensive care unit, gastrointestinal dysfunction and fecal incontinence are common, the average number of bowel movements per day increases, defecation cannot be warned, and exposed defecation causes corrosion of the perianal and perineal skin, and pollution of the urinary tract and surrounding environment.
[0003] The defecation cleaning of disabled people causes many clinical pain points, including: 1. Unpredictable defecation. 2. Cleaning takes up a lot of nursing time. On average, it takes at least 20 minutes to clean a stool, or even longer, which greatly reduces the time of medical care and reduces the quality of medical care. 3. Defecation cleaning takes up manpower and cannot be done alone. Generally, at least two or more people are required. 4. Sanitary products are expensive. One defecation generally consumes at least two medium-sized nursing pads or a diaper, half a pack of large wet wipes and half a pack of dry paper towels, and the cost is estimated to be around 30 yuan. If the loose stool stains the sheets and bedding, causing the bedding to be scrapped, the cleaning cost will increase significantly. 5. Environmental pollution. Exposed defecation not only causes bed unit pollution and contact transmission of fecal bacteria, leading to nosocomial infection outbreaks and endangering the lives of patients; at the same time, the fecal odor of exposed defecation also seriously affects the respiratory health of medical staff and patients. 6. Skin lesions around the anus and perineum do not heal for a long time. Due to the inability to detect and deal with the patient's bowel movements in time, repeated wiping with tissues or soaking in loose stools can lead to eczema and ulcers on the skin and mucous membranes around the anus and perineum that do not heal for a long time, causing great pain to the patients, and also leading to a decline in nursing quality and an increase in medical disputes.

When enema is not needed, the enema tube 409 is disassembled and taken out, and the enema hole is tightly covered with the fifth closed screw cap 404 to seal the excrement guiding hose 2.
[0049] In one embodiment of the present invention, a host device is also included, which is arranged on the body, and has monitoring and alarm functions, cleaning drive and termination functions, metering and statistics functions, and enema drive and termination functions; the body 5 has a door 56, and the door 56 has a first display screen 57, a button 58, and a handle 59. The first display screen 57 can display data, such as the amount and time of each defecation, the weight of the feces collection bag 3, the number and total amount of defecation in 24 hours per day (7:00-06:55 the next day). The host device senses the alarm signal, starts and terminates the cleaning and flushing process, and analyzes and displays the metering data; the squeezing water bag 405 is a tough expansion metering water bag (50ml), and the water bag is compressed under the adjustment of the host to form a forward jet flow.
[0050] The cleaning drive and termination function, enema drive and termination function: in the ready state, the second solenoid valve 54 is closed, the first solenoid valve 53 is opened, water is poured into the squeezing bag 405 from the water storage tank 407, and after the water level sensor 55 detects the water level, the first solenoid valve 53 is closed, and the host device is in a flushing or enema standby state. When cleaning or enema is required, the squeezing plate 52 is driven by the two electric push rods 51 to pressurize the squeezing bag 405, and the second solenoid valve 54 is opened to form a forward pressurized jet flow. The water level sensor 55 is both a metering device for the squeezing bag 405 and an alarm device for empty water tanks.
[0051] In one embodiment of the present invention, the enema hole is opened in the excrement guiding hose 2 and is 10 cm away from the anus, with a diameter of 3 cm; the enema tube 409 is a flexible round-headed hollow tube with a plurality of holes on the tube head.
[0052] In one embodiment of the present invention, the inner wall of the excrement guiding hose 2 can be provided with a smooth water-slip coating. The smooth water-slip coating can be a liquid lubricant, but is not limited to this. It can make the inner wall of the excrement guiding hose 2 become a very smooth surface, thereby achieving a non-stick effect, preventing feces from adhering and being difficult to flush.
[0053] The excrement guiding hose 2 can be designed to be soft and have a micro-magnetic inner cavity. When the excrement guiding hose 2 is idle, the inner walls are attracted to each other and collapsed, which helps to push the excrement into the feces collecting bag 3 by hand, avoids compressing the limbs, prevents water accumulation and flushing of dead corners.
[0054] In one embodiment of the present invention, the feces collecting bag 3 is a 5-liter rectangular silica gel bag with a thin layer and strong flexibility.
[0055] In one embodiment of the present invention, the measurement and statistics function: the spring electronic scale 6 has the functions of a second display screen, initial zero calibration, wireless data transmission, and weight near saturation alarm. The second display screen displays the real-time weight and the difference before and after each treatment, and the data is wirelessly transmitted to the host device for summary statistics to obtain the weight of each defecation (G); a saturation alarm function is set, and when the real-time weight of the feces collection bag 3 reaches 90% of the saturation weight, an early warning message will be issued to remind the replacement of the feces collection bag 3 or the emptying of the feces collection bag 3.
[0056] In one embodiment of the present invention, the monitoring and alarm function: the front infrared probe 203, the middle infrared probe 204 and the rear infrared probe 205 are all miniature infrared wireless monitoring probes, and their wireless signals are transmitted to the host device to play the function of defecation alarm, starting and terminating pipeline cleaning. The front infrared probe 203 is set at 5 cm from the anus, the middle infrared probe 204 is set at 30 cm from the anus, and the rear infrared probe 205 is set at 60 cm from the anus. When the front infrared probe 203 detects defecation, it is transmitted to the host device 5 to issue an alarm, reminding the nursing staff to observe the defecation characteristics and subsequent disposal, and prepare to start cleaning to reduce the contact time between feces and the perianal mucosa. When the middle infrared probe 204 and the rear infrared probe 205 detect residual feces, the cleaning flushing is terminated, and the feces are pushed by hand, which helps to shorten the cleaning time and save water.
[0057] In one embodiment of the present invention, this embodiment provides two cleaning modes:
[0058] Fully automatic mode: When the front infrared probe 203 detects defecation, a short alarm is issued, and the defecation is finished after 10 minutes, and the cleaning flushing is started until no significant feces water is detected by the middle infrared probe 204 and the rear infrared probe 205, and then the process is terminated.
[0059] Semi-automatic mode: the front infrared probe 203 detects defecation and issues a long alarm. The medical staff cancels the alarm, evaluates the properties of the stool, and manually starts the cleaning flush. If the alarm continues for more than 20 minutes without being canceled, the system automatically starts the cleaning flush to prevent the stool from being retained for too long.
[0060] In one embodiment of the present invention, the cleaning can be performed directly by manually squeezing the water squeezing bag 405 without the need for a driving device.
[0061] The above description is only a preferred embodiment of the present invention and should not be construed as limiting the present application. All equivalent changes and modifications made within the scope of the patent application of the present invention should fall within the scope of the present invention.
