Description

Technical Field

[0001] The present invention is a technical defecation care product for reducing the burden on caregivers for those who have difficulty controlling defecation by themselves, those who are physically and mentally burdened by excretion treatment during hospitalization or home care, etc.

Background Art

[0002] In Japan, the population aged 65 and over was less than 5% of the total population in 1950, exceeded 7% in 1970, and exceeded 14% in 1994. The aging rate has continued to rise since then and reached 28.9% as of October 1, 2021. According to the White Paper on the Aging Society 2020 published by the Cabinet Office, in the projected future population, the population of Japan in 2065 will be less than 90 million, with one out of every 2.6 people aged 65 and over and about one out of every 3.5 people aged 75 and over. The number of certified care recipients (requiring support) in 2021 is approximately 6.82 million (e-Stat government statistics). In the phenomenon of hyper-aging society in Japan where the average life expectancy is increasing and the number of care recipients is increasing, problems related to caregiving such as "caregiving refugees", "caring for the elderly by the elderly", "abuse of the elderly", and "shortage of personnel in care facilities" have occurred. In an aging society, various caregiving problems occur, so the demand for caregiving staff increases, and there are also problems that can be solved if the number of caregiving staff increases. The effective job offer ratio for caregiving positions is 3.82 times, indicating that the number of job offers in the caregiving industry is large compared to the number of job seekers. The fact that there are many job offers means that the facilities are short of staff. According to a survey, the percentage of those who replied that "there is a shortage of caregiving staff" was 47.3%. The percentage of those who replied that "there is a slight shortage of caregiving staff" was 36.7%, and more than about 80% of care facilities feel that they are short of staff.

[0003] According to the annual survey of the Care Workers' Employment Stabilization Center in 2021, the turnover rate in the care industry is 14.1% for care jobs in one year. According to the Labor Force Survey of the Ministry of Health, Labor and Welfare, the turnover rate averaged across all industries is 13.9%. Although it is a different survey, for the year 2021, the turnover rate of care jobs exceeds the average of all industries by 0.2 percentage points. Also, except for 2019, the average turnover rate of care jobs has exceeded that of all industries. Various reasons for leaving are cited, such as ▲1▼ human relations, ▲2▼ heavy physical burden, ▲3▼ excretion assistance, ▲4▼ dissatisfaction with management policies, ▲5▼ low salary, etc. According to the Cabinet Office, more than 60% of care experience holders answered that they had difficulty with excretion assistance. Excretion assistance, which is one of the factors for the turnover of care staff, also has a large workload, and 40% of the night-time nurse calls at care sites are for excretion assistance. Excretion assistance is an important job that involves all aspects of assisting the excretion of care recipients, such as assisting with movement to a wheelchair or toilet, changing diapers, and assisting with taking off and putting on clothes. The scope of care workers' labor, such as checking the state of the care recipient's excrement and grasping their health condition, is wide-ranging and burdensome.

[0004] Selecting appropriate tools for care leads to more comfortable care. In addition to the psychological care of care recipients, using technical care products can also reduce the labor of care workers. Currently, a large number of technical care products have emerged, which is leading to a reduction in the burden on care workers.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In an aging society like Japan, there is a high demand for care staff, but there are few applicants for care jobs. Also, the turnover rate is high compared to other occupations. However, there are many problems that cannot be solved by simply increasing the number of care staff. In terms of care content, excretion assistance has a large workload and is physically demanding, so it is currently one of the causes of turnover, along with human relations.

[0006] The present invention aims to solve the problems of difficult self-control of defecation, fecal incontinence (leakage of feces), liberation from diapers, and reduction of the workload of caregivers in assisting with excretion. It is a technical care product designed to reduce the turnover rate of caregivers due to the reduction of the excretion assistance work and increase the number of new caregivers.

Means for Solving the Problems

[0007] The anal insertion type defecation device of the present invention is an excretion unit that enables people with fecal incontinence (leakage of feces), people with difficult defecation, and people with diseases who have difficulty defecating naturally to excrete freely and painlessly. This unit consists of a tip integrated with a fluid tube and a storage bag. The tip is made of a super soft material, compressed into a bullet shape, and inserted into the rectum from the outside of the anus using a dedicated applicator. The inserted tip expands into a funnel shape with holes in the rectum, and the feces to be excreted are collected in the odor-proof storage bag attached to the outside of the anus, whether the wearer is conscious or unconscious, and can be excreted naturally at any time.

[0008] The length of the human anal canal is about 30 mm to 40 mm, and there is a dentate gland at a position about 15 mm from the anus entrance. Provide a care product that is inserted and retained in the painless part of the intestine above the dentate gland without causing pain or a foreign body sensation to the user.

[0009] The material of the tip is made of a super soft material, and its shape is bullet-shaped. It is wrapped in an oblate or gelatin and glycerin, or gelatin and sorbitol capsule to facilitate insertion into the intestine. The oblate or capsule is naturally decomposed in the intestine and at the same time gradually spreads into a funnel shape to cover the inner wall of the rectum and is designed to be excreted naturally. The insertion method is also simple, with the same simplicity as inserting a suppository and high convenience. The length of the tip inserted from the anus is about 30 mm to 50 mm, and a flange is provided with an anti-insertion grip to prevent excessive insertion into the rectum. The tip of the anal insertion defecation device is equipped with a double removal string to prevent the tip from remaining when removed. To ensure that the amount of feces excreted from the funnel-shaped tip is not affected, slits are made in the round hole connecting to the fluid part to accommodate all types of feces. In addition, it is also characterized by providing anti-backflow in the fluid part.

[0010] The storage bag uses odor-proof materials such as paper, polypropylene, and polyethylene, and is made of a colored material so that the texture, odor, and color of the contents cannot be felt. However, when feces analysis is required for health management, a transparent storage bag is used, and a material that allows the contents to be confirmed is used.

[0011] The method of inserting the tip into the rectum uses a dedicated applicator. The tip with a compressed fluid tube inside the inner cylinder and the storage bag are set. When in use, lubricating gel is applied to the tip of the applicator so that it can be inserted smoothly. Then, using the pusher (piston part), it is gently inserted into the rectum from the anus in the same way as a suppository. After confirming that it has been inserted, the applicator is removed. The tip inserted by the applicator instantly spreads into a funnel shape in the intestine. After absorbing moisture in the intestine, it expands, with a diameter of about 37 mm for the S size and 45 mm for the L size, and a wall thickness of 4 mm, enabling smooth excretion of intestinal contents.

[0012] To prevent the tip from being unable to be removed from the rectum, a safety design is implemented where gauze is spirally attached inside the material of the tip, integrated with the tip, made into a string shape, and hung inside the storage bag. This string is used both after excretion and when removing the tip from the body. The maximum retention time of the tip in the rectum is within 12 hours, and it should be replaced regularly.

[0013] The anal insertion type defecation device is worn with a dedicated girdle so that it can be used even during movement. It is made of an odor-proof material so that it can cope with subtle fecal incontinence and prevent odor from leaking outside. In order for the user to fix the anal insertion type defecation device, a fixing girdle is worn from above. For those with a tendency to play with feces, fixing belts are worn on the abdomen and thigh parts to prevent hand insertion.

[0014] The present invention is also characterized by respecting the self-esteem of both the caregiver and the care recipient, reducing pain and labor, and is a useful care product from the viewpoint of not lowering the quality of life. Problem

[0015] The mass-produced anal insertion type defecation device is excellent in economy, and is provided as a technical care product that can reduce the labor of excretion assistance work for those engaged in care work, relieve the guilt of the care recipient being assisted with excretion, and relieve mental problems such as shame. Means for Solving the Problem

[0016] The anal insertion type defecation device of the present invention is a technical care product that can save labor in excretion assistance for those who have difficulty controlling defecation by themselves, those who tend to leak feces, those who are cared for at home, and those who are hospitalized long-term in a facility. Effects of the Invention

[0017] More than 60% of caregivers with care experience answered that they had difficulty with excretion assistance. Excretion assistance, which is one of the reasons for caregivers to leave their jobs, also has a large workload. Since 40% of the night-time nurse calls at the care site are for excretion assistance, it is hoped that it will lead to a reduction in the labor force of caregivers, a decrease in the turnover rate of care workers, and an increase in new care worker applicants due to the improvement of care services.

Mode for Carrying Out the Invention

[0019] An applicator unit having the structure shown in FIG. 12 was manufactured. In an applicator (made of polyethylene) with a length of 130 mm * 15Φ, ▲1▼ the tip (material: polyurethane / silicone rubber / isoprene rubber / stretch rubber, 35 mm to 47 mm when opening in the rectum), ▲2▼ the flow tube is 15 mm, and the storage bag weighs 5 g (material: paper / polypropylene / polyethylene, etc.) are mounted and fixed inside the applicator, and one unit has a total weight of within 35 g. As a result, when the caregiver uses the anus-insertable defecation device for the care recipient, it is hygienic, small and lightweight, and highly convenient for excretion treatment with simple operation. Comparative Example

[0020] Among commercially available and obtainable general excretion treatment products, there are diapers. Adult diapers come in various shapes such as pants type, tape-fastening type, and other subtypes. The average price of one is from 60 yen to 80 yen, and those for caregiving are around 150 yen. However, with the diaper type, it is inevitable to feel visual, olfactory, tactile sensations of mass, etc. during excretion assistance. In the present invention, since the inserted tip sends the rectal excrement through the flow tube into the storage bag, it is characterized by minimizing discomfort caused by vision, smell, mass, etc.

Industrial Applicability

[0021] The phenomenon of population aging in Japan is manifested as a major issue related to nursing care. The number of certified nursing care recipients in 2021 is approximately 6.82 million, and among them, there are many people who have difficulty controlling defecation on their own and need assistance from caregivers for excretion. The anus-insertion type defecation device of the present invention can be produced at low cost during mass production, and it helps to save the labor of nursing staff, reduce the turnover rate, increase the number of people willing to work in the nursing care field, and reduce the assistance provided by in-home caregivers for the aging society in Japan.

Claims

1. The present invention is characterized in that the defecation device is inserted (Fig. 2-3▲2▼) into the rectum from the anus (Fig. 2-3▲1▼), and the inserted tip (Fig. 2-3▲3▼) expands into a funnel shape (Fig. 2-3▲4▼) inside the rectum, and whether the wearer is aware of it or not, it is placed into a storage bag (Fig. 2-10) attached to the outside of the anus through a hole (Fig. 2-3▲5▼ / top view) opened in the center bottom of the tip.

2. The length of the human anal canal is approximately 30 to 40 mm (Figure 1-▲9). The dentate line (Figure 1-▲5) is located approximately 15 mm from the outside of the anus, and the anal canal is divided into the anal region and the rectal region (Figure 1-▲1▼) at the dentate line. It is known that the anal region is under the control of the spinal nerves and is therefore sensitive to pain (Figure 1-▲7▼), while the rectal region is controlled by the autonomic nerves and is therefore painless (Figure 1-▲6▼). The tip of the anal insertion type defecation device of the present invention (Fig. 2-11) is characterized by being inserted and left in a painless area in the rectum behind the dentate line so that the wearer does not sense pain or a foreign body sensation.

3. The anal insertion type defecation device can be made up of three parts: a tip, a flow tube, and a storage bag, or it can be made up of two parts, with the tip and flow tube integrated and directly connected to the storage bag. The flow tube is equipped with a backflow prevention valve to prevent the backflow of feces. A special applicator is used to insert the tip from the anus.

4. The tip is made of super soft material, polyurethane, elastomer, urethane gel, silicone rubber, isoprene rubber, etc., and the tip is folded into a bullet shape so that no pain is felt when inserted, and is wrapped in an oblate, gelatin, glycerin, or gelatin-based capsule. These naturally decompose in the intestine and gradually expand into a funnel shape to cover the inner wall of the tip of the rectum near the anus. The contents of the intestine are excreted through a hole opened in the center of the tip, and the feces are designed to be quickly collected in a storage bag through a flow tube.

5. The length of the tip of the anal insertion type defecation device is basically 30 to 40 mm, with a tolerance of 10 to 80 mm. To prevent the tip from going too far into the rectum, a finger grip (Fig. 2-6) is provided on the dedicated applicator (Fig. 3-12) to prevent it from being inserted too far into the rectum.

6. The tip of the anal insertion type defecation device is designed with a double-spiral removal string to ensure that the tip is not left behind in the rectum when the user replaces it.A round hole (Figure 2-3▲5▼) is drilled at the tip so as not to affect fecal excretion, and cuts are made around the hole to allow for the use of various types of excreta.

7. The flow tube is for the smooth passage of excrement, and is made of a flexible material to accommodate both large and small feces, and functions to smoothly send the excrement into the storage bag. The length is in the range of 20 mm to 60 mm, and the material is a deodorizing colored material that does not allow the texture, odor, or color of the contents to be felt. If medical analysis is required, the storage bag shall be transparent.

8. The storage bag is a functional body for receiving and pooling waste from within the rectum, and is characterized by its ice pack-like structure (Figure 2-10) made of materials such as paper, polypropylene, and polyethylene that have excellent odor-resistant properties and are leak-proof, break-proof, and odor-resistant.

9. The user fixes the anal insertion type defecation device unit with a special girdle over the anal insertion type defecation device, so that it can be worn when moving around. The special girdle is also effective as a measure against defecation play, and belts are attached to the abdomen and both thighs to prevent hand insertion, which is also an effective measure.
