Abstract
Description
Technical Field
[0001] The present invention attaches importance to the autonomy of people who have difficulty standing up and walking on their own (hereinafter referred to as "people with walking difficulties"), and by utilizing a box-pierced mattress at night, provides a method that enables excretion in a self-seated position beside the bed.
Background Art
[0002] With the progress of the aging society and the nuclear family trend, difficulties in dealing with excretion such as nocturia have emerged in institutional care and home care. The decrease in the number of caregivers has also added to the problem. In particular, frequent excretion assistance at night is not carried out as desired, and the use of diapers leads to skin erosion and the worsening of bedsores, increasing the burden on caregivers. The present invention aims to avoid the fall of people with walking difficulties who cannot go to the toilet on their own, protect their self-esteem and privacy, and at the same time, reduce the burden on caregivers (hereinafter referred to as "caregivers").

[0004] Sit on either side of the bed where the box is pierced on both sides of the mattress, enabling excretion behaviors such as urination in a seated position.
[0005] Respecting the autonomy of people with walking difficulties, promoting self-seating, and self-implementation tend to have positive effects such as mental calmness. It helps them find their own ways, enhances their awareness of "wanting to do this" and "doing this", and promotes decision-making and effectiveness. It also leads to a reduction in the burden on caregivers.
[0006] In addition to seated excretion while respecting autonomy, by undergoing rehabilitation such as independent lower limb exercises and physical therapy, muscle strength and walking ability can be improved, and the feeling that it might be too difficult may gradually change, leading to confidence in performing tasks independently and being able to do so smoothly.
[0007] By providing appropriate nutrition and proper nursing and care, the immunity and natural healing ability associated with maintaining and restoring physical strength and body functions are improved, fostering the self-reliance of those with difficulty walking.
[0008] Avoid a life centered around diapers in a bedridden state. Through assisted bedside seating and respiratory therapy and training of the respiratory muscles, the respiratory function can be improved so as not to lose confidence.
[0009] To prevent bedsores resulting from a bedridden state, the pressure is dispersed by appropriately changing positions and the bedside seating posture.
[0010] Promoting independent excretion behavior and maintaining the rest and refreshment of caregivers lead to the maintenance of the health of both.
[0011] By maintaining the autonomy of those with difficulty walking and sustaining their motivation, caregivers can engage in communication and have the leeway to remove psychological anxiety.
[0012] When caregivers can understand the feelings and hopes of those with difficulty walking and have the leeway to strive to reduce psychological stress and loneliness, they can explain the necessity of assistance, remove the sense of humiliation, and be mindful of providing appropriate and effective help.
[0013] By paying attention to the surroundings of those with difficulty walking, taking care to provide a comfortable bed, appropriate room temperature, clean environment, and pleasant living space, and taking preventive measures to minimize the risk of falls and injuries, handrails and other supports and assistive devices can be selected as needed.
[0014] If a person with difficulty walking is receiving specific treatment or prescription drugs, improving the condition can be achieved by continuing to take the appropriate drugs and receive treatment in cooperation with a doctor.
[0015] On the premise of determining the necessity for a person with difficulty walking, a box-pierced mattress is provided. Especially when defecating or urinating, many people show resistance to entrusting others with toilet assistance. By molding the mattress as shown in Figure 1 of the drawings, the box toilet seat can be used when necessary at night or the box-drawer can be removed, and disposable urine pads or paper diapers made of polymer absorbent materials can be stacked in the depression, enabling self-excretion without borrowing the help of others, without skin contamination, easy post-treatment, and leading to fall prevention. Effects of the Invention
[0016] A box-pierced mattress that allows a person with difficulty walking to sit on the bedside independently, with the soles of the feet touching the floor for stability, enabling excretion in that body position. Although excretion while lying in bed is physiologically difficult, when in a sitting position on the bedside, it is in the same position as a Western-style toilet, making excretion easier. Wearing diapers hurts self-esteem and causes a loss of motivation. This method enables self-excretion without borrowing the help of others and does not damage self-esteem.

[0018] Regarding the embodiment. The pierced box generally has a depth of 40 centimeters, a width of 30 centimeters, and a height of 10 centimeters with a lid, and can be made of a sturdy material such as resin, stainless steel, or polyester. It can be inserted from the side of the mattress and is easy to pull out and wash.
[0019] As shown in Fig. 1, since the installation location of the drilling box varies depending on the room specifications, the drilling box is provided at two positions on the left and right sides of the mattress, and either one of them can be used.
[0020] The mattress and sheets are in a three-sheet specification of upper, middle, and lower. The middle sheet is for high frequency of getting dirty and for the convenience of replacement.
