Abstract
Description
[Technical Field]
[0001] The present invention is a device that assists urination and defecation functions in independent daily living. [Background technology]
[0002] Numerous devices and equipment have been proposed up until now, such as bulky disposable diapers, but they are not only difficult to use, but also uncomfortable to wear, which reduces motivation to be active and leads to refraining from going out, which can lead to other illnesses, and the environment has not improved.

[0004] Summary of the Invention [Problem to be solved by the invention]
[0005] To provide a urination and defecation assisting device which has a shape that is difficult to distinguish from the outside when worn, can be easily worn, can be used simply, can collect and store a large amount of urine and feces, and can be easily discharged. [Means for solving the problem]
[0006] By cutting open one side (3) of a resealable resin bag (1) that is continuous with the opposite side (5) of the resealable part (2), and then opening a large hole in the center of the bag and separating the joint (4) of the two cut sides, the remaining side (7) and the resealable part (2) form a loincloth-shaped bag with an internal space. The two separated sides can be used as waist straps (3a, 3b) (5a, 5b) for wearing, and the space can be used as a container for collecting and storing urine, feces, etc., making a low-cost urination and defecation aid. [Effects of the Invention]
[0007] By changing the length of the zipper (2) of the zippered resin bag (1) and the depth of the bag, the internal volume of the bag can be changed, making it suitable for people of all sizes, from petite women to overweight men. By using the zippered resin bag (1), the thin bag fits snugly against the genitals and thighs, so that others cannot see from the outside that a urination and defecation aid is being worn. By modifying the existing zippered resin bag (1), reusable urination and defecation aids can be provided at low cost. [Brief explanation of the drawings]
[0008] [Figure 1] 1 is an explanatory diagram showing an instrument of the present invention. [Figure 2] FIG. 1 is an explanatory diagram showing the appearance of the device of the present invention when worn.
[0009] Figure 1 is an overall view of a urination and defecation aid. An incision (3) is made on one side of the edge of a resealable plastic bag (1) starting from the welded part at the end of the zipper (2) from a position (8) that does not affect the closure of the zipper (2) toward the opposite side of the zipper (2). An additional incision (5) is made from the incision edge (4) toward the opposite side of the edge (7). The edges of incisions (3) and (5) on both the front and back membranes are reinforced with tape or the like, and the ends are made into string-like shapes (3a, 3b) (5a, 5b). An incision is made from the incision edge (4) toward the inside of the bag, cutting out the center of the resealable plastic bag (1) in a roughly heart shape and creating a hole. Tape-like strings (6a, 6b) are attached to the central corners (6) of the heart on both the front and back membranes. The notch (5) side of the heart-shaped bulge is curved to securely fit the device to the waist, and the zipper (2) side of the heart-shaped bulge is curved to fit the device to the genitals in order to accommodate the area from the anus to the penis. The starting point (8) of the notch (3) is reinforced with tape or similar. DETAILED DESCRIPTION OF THE INVENTION
[0010] One side of the edge of the zippered plastic bag (1) starting from the welded part at the end of the zipper (2) is reinforced with tape or the like at a position (8) that does not affect the closure of the zipper (2), and an incision (3) is made from that position toward the opposite side of the zipper (2), and an incision (5) is made from the incised end (4) toward the opposite side (7). The edges of the incisions (3) and (5) on both the front and back membranes are reinforced with tape or the like, and the ends are made into string-like shapes (3a, 3b) (5a, 5b). An incision is made from the incised end (4) toward the inside of the bag, and the center of the zippered plastic bag (1) is cut out in an approximately heart shape, a hole is made, and tape-like strings (6a, 6b) are attached to both the front and back membranes at the central corners (6) of the heart. [Example]
[0011] The zippered plastic bag (1) has a zipper (2) with a length of 200 mm or more and a width of 300 mm or more, and the thickness of the bag is 0.04 to 0.2 mm. One side of the edge of the zippered plastic bag (1) starting from the welded part at the end of the zipper (2) is reinforced with tape at a position (8) that does not affect the closure of the zipper (2), and an incision (3) is made from that position toward the opposite side of the zipper (2), and another incision (5) is made from the incision edge (4) toward the opposite side (7). The edges of the incisions (3) and (5) on both the front and back membranes are reinforced with tape, etc., and the ends are made into string-like shapes (3a, 3b) (5a, 5b). Further, a cut is made from the cut end (4) toward the inside of the bag, cutting out the center of the resealable resin bag (1) in roughly a heart shape to make a hole, and tape-like strings (6a, 6b) are attached to both the front and back membranes at the central corners of the heart (6). Attaching hook-and-loop fasteners to the strings (3a, 3b) (5a, 5b) (6a, 6b) makes it easier to attach the device.
[0012] To use the device, first cut open the crotch of disposable pants vertically to prevent sweat rash. For men, a tubular bandage is placed over the penis to reduce friction with the plastic bag. After opening the strings (5a, 5b) and securing the device to the waist with the opposite side (7) facing the lumbar vertebrae, strings (3a, 3b) are passed through the inner thighs and through the inside of the waist strings (5a, 5b). Tie strings (3a) and (6a) together, and then tie strings (3b) and (6b) together. The bag-shaped plastic bag enclosed by the opposite side (7) and zipper (2) encases the area from the anus to the penis, and the zippered plastic bag (1) serves as a container for the penis and a receptacle for feces and other excrement. When urinating in the toilet, opening the front zipper (2) allows for normal urination without removing the device. After emptying the collected waste, the device can be washed and reused. It can be used by both men and women. Using a resin fabric reinforcing tape reduces stretch, preventing loosening after application and reducing discomfort when it comes into contact with the skin. The area between the opposite side (7) and the zipper (2), which forms the waste collection area, can rub against the inner thigh when the device is worn. Applying an adhesive bandage or fixing tape to the outside of the bag is recommended. Similarly, the area near the incision (5) on the inside of the opposite side (7) also comes into contact with the skin, so applying an adhesive bandage or fixing tape is recommended. Placing a polymer absorbent or deodorizer inside the zippered plastic bag (1) solidifies leaked urine, reducing the sound and odor of water when moving the bag. For those with limited dexterity, using a bag with a slider (9) on the zipper (2) allows for quick opening and closing of the zipper (2). If you are concerned about the closure of the zipper (2), you can use a zippered plastic bag (1) with two rows of zippers (2). During normal urination, men can urinate forward while standing without removing the device. Even if you are unable to urinate or defecate in time and the device leaks, opening the front zipper (2) makes it easy to expel accumulated feces and urine. The urination and defecation aid can be reused, making it low-cost to operate. By making the length of the zipper (2) longer than the other three sides and processing the opposite side (7) into a stepped shape, it can also be used while sitting, such as when driving a car. By adjusting the position (8) that does not affect the closure of the zipper (2) and the spacing of the zipper (2), it is possible to distinguish between male and female anatomy. To increase the fit, it is recommended to hang the end of the zipper (2) and the rear waist area of the opposite side (7) with a hanging band. [Explanation of symbols]
