Abstract
Description
[Technical field]
[0001] This pants-type robot automatically processes urination and defecation. The computer detects odors in the washing room with an odor sensor, activates the high-pressure water pump to start washing, and at the same time activates the washing and drying forced air fan to wash and dry. Almost at the same time, the treated waste and wastewater are treated with a drainage pump with crushing blades. All functions are controlled by computer, and the cleaning of the washing room is completed. The situation in the cleaning room is photographed with lighting and a miniature camera installed in the cleaning room, and the status of cleaning and drying is displayed on an external TV monitor, so you can see everything that is happening in the cleaning room. The cleaning room is equipped with a lid for performing maintenance and inspection of the computer and power supply, as well as a lid for manual inspection of the sewage treatment room, so that the sewage treatment room can be inspected at any time, and the current state of the treatment room and the status of sewage treatment can be checked and taken care of at any time. [Background technology]
[0002] The most difficult task in nursing care is the disposal of urination and defecation. In particular, disposal of urination and defecation of bedridden patients is a heavy burden, and at the same time, the burden on nurses and caregivers is large, and in modern society where the working population is decreasing, this burden will continue to be huge. If this arduous task could be automated using computer-controlled pants-type robot technology for urination and defecation, the workload in nursing care facilities would be greatly reduced. This also greatly reduces the burden on families in the field of home care. It will also greatly reduce the burden of caregiving on young carers, which has recently become a social issue. At the same time, it will also reduce labor costs, which will lead to reduced care costs. [Prior art documents]
[0003] I searched online but couldn't find anything that fit the criteria. Summary of the Invention [Problem to be solved by the invention]
[0004] The work of caregivers and nurses in the nursing field is very tough. In particular, changing the diapers of bedridden patients is a difficult task that requires three caregivers. In fields where there is a shortage of caregivers, changing diapers is a heavy burden. Caregivers are required to have excessive physical strength, and some end up damaging their health, making it a harsh reality. In addition, the problem of a declining labor force is serious, and there is a need for foreign personnel. To solve these problems, we have devised a pants-type robot that can handle urination and defecation. [Means for solving the problem]
[0005] This proposal is This was devised to replace the task of changing diapers, which has become a major burden in nursing care settings, by using a computer-controlled pants-type robot to handle urination and defecation of patients without human assistance. First, the odor sensor detects waste, and the high-pressure water washing pump is activated. At the same time, the washing and drying forced air fan, which assists in the washing and drying functions, starts blowing air to assist in the washing and drying. At almost the same time, the drainage pump with crushing blades starts working, draining the washed waste. This process is filmed by the built-in camera and displayed on an external monitor, allowing you to check the internal work in the washing room. In this way, all work is performed by the urination and defecation processing pants-type robot, reducing the excessive workload of nurses and caregivers and leading to a reduction in manpower. Effect of the Invention
[0006] As mentioned above, all tasks are performed automatically by the pants-type robot for urination and defecation, which can contribute to reducing the burden on nurses and alleviating manpower shortages. [Brief description of the drawings]
[0007] [Figure 1]The detailed diagram is a detailed diagram of the automatic urination and defecation processing pants-type robot, and the functions of the robot are clearly described in detail. (1) Computer box (main computer program system), (2) Odor sensor detects and activates all functions, (3) Air outlet, (4) Washing / drying forced air fan operates to wash and dry the discharged waste and assist in the discharge of waste, (10) High pressure washing pump passes through (5) Water supply pipe, and washing water is discharged from (6) Fountain washing faucet to wash the waste. The washing water stops before other functions, and the washing / drying forced air fan operates until the end to dry and forcibly discharge the wastewater. (7) Wastewater and wastewater are processed by the drainage pump with crushing blades, and when all waste processing work is completed, all functions stop and all cleaning work is completed. (8) An internal surveillance camera displays all processes in the cleaning room on a video monitor, allowing the user to check whether the cleaning is complete. [Diagram 2] The development diagram shows the overall shape of the urination / defecation processing pants-type robot, the system functions, and the entire device body at a glance. The names of the functions, the layout of the system equipment in the cleaning room, and each system are clearly shown at a glance. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0008] The pants-type robot for automatic urination and defecation processing fits snugly around the waist of a bedridden patient and controls all functions from cleaning waste from between the patient's legs to drying and draining, all of which are controlled by a computer. As the robot controls and processes each function, it significantly reduces the burden on nurses and caregivers. The progress of waste disposal between the patient's crotch areas is displayed on an external monitor and a camera installed in the washing room, so the situation inside the washing room can be seen at any time. EXAMPLES
[0009] The implementation process will be explained below with reference to the drawings. The automatic urination and defecation pants-type robot is designed so that all of its functions are controlled and operated by a computer program. First, the odor sensor detects the smell of waste and activates the washing / drying forced air fan, high-pressure water washing pump, and pulverizing blade drainage pump to wash the patient's groin in the washing room. After that, the water supply pump stops supplying water first, and the pulverizing blade drainage pump forcibly drains the water while the forced air fan assists in drying and forced drainage, completing the treatment of the patient's waste. The state of the washing room is photographed by an internal camera and displayed on an external monitor, and the entire process from the start of washing to the completion of drainage can be monitored on the external monitor. This condition was verified by conducting partial experiments using a model with separate functions. [Explanation of symbols]

Claims
[Claim 1] This idea is the invention of a pants-type robot that can fully automatically handle the most difficult part of nursing and caring for bedridden patients, urination and defecation, all of which is computer-controlled and is made of a small, form-fitting diver suit fabric and a plastic molded main mechanic box. The five functions of the automatic urination / defecation pants-type robot are as follows: The computer system that is the brain of this invention first detects an odor with an odor sensor, and then automatically activates the three functions of washing, drying, and draining. (1) The odor sensor detects odors inside the pants and sends a command to the computer, which then operates the (2) high-pressure water washing pump to begin washing the waste from the patient's groin, and at the same time operates the (3) forced washing and drying fan to wash and dry the groin waste treatment room with a time lag. At the same time, (4) the pulverizing blade drainage pump is operated to drain the wastewater from the groin waste treatment room. (5) The lighting is for illuminating the inside of the groin waste treatment room. (6) The washing room surveillance camera monitors the situation inside the groin washing room by displaying it on an external monitor screen. In this way, all functions are controlled by computer and operate fully automatically, completing a series of tasks without human intervention, which helps to alleviate the labor shortage and reduces the burden on nurses and caregivers.
