[0002] This patent application relates to a stool collection component and a nursing machine, and more particularly to the design of a connecting frame for the external connection of the stool collection component's trouser-covering device. Background Technology

[0003] A nursing care machine is a human defecation suction and cleaning device used to clean patient excrement. A nursing care machine typically includes a main unit, a working head, a trouser cover, and suction and water supply pipes connecting the working head and the main unit. The main unit is equipped with a negative pressure source to provide power for suction, a water supply tank to hold clean water, a waste tank for storing excrement, and a water pump. The negative pressure source includes a motor and an impeller. The impeller rotates under the drive of the motor to generate suction airflow to suction human excrement. CN217138536U discloses a defecation collection component of a nursing care machine, including a trouser cover for wearing on the body and a working head detachably connected to the trouser cover. The working head has a trough (urinal) for receiving human excrement. The trouser cover includes trousers and a connecting bracket connected to the trousers. The trouser cover has a crotch opening for excretion during human defecation. Waste can fall into the latrine through the crotch opening. The connecting bracket forms at least a part of the crotch opening and is used to connect the trouser-covering device to the working head. The connecting bracket has a first U-shaped part, a left connecting part, a second U-shaped part, a right connecting part, and a second U-shaped part connected in sequence to form the crotch opening. The first U-shaped part surrounds the front end of the crotch opening, and the second U-shaped part surrounds the upper end of the crotch opening. The left and right connecting parts are located on the left and right sides of the crotch opening. The left and right connecting parts are attached to the trousers. The front surfaces of the left and right connecting parts are directly attached to the trousers. The left and right connecting parts are not easy to squeeze between the legs of the human body, especially when the space between the legs of the patient is relatively narrow. This makes it difficult for the crotch of the waste collection component to be put on properly. Therefore, the ease of wearing this trouser-covering device needs to be improved. Summary of the Invention

[0004] The technical problem solved by this patent application is to improve the ease of wearing the panty-covering device of the fecal collection component.

[0005] A waste collection assembly includes a trouser cover and a working head.

Detailed implementation manners

[0047] Refer to Figures 1 to 11As shown, the trouser device 1 in this patent application is for wearing on the human body, including trousers 2, a connecting frame 4 connected to the trousers 2, and a crotch opening 10 located in the crotch area of ​​the trouser device 1 for human excretion. The connecting frame 4 forms at least a portion of the crotch opening 10. The connecting frame 4 has a left connecting portion 40 located on the left side of the crotch opening 10 and a right connecting portion 41 located on the right side of the crotch opening 10. The left connecting portion 40 has a first inclined outer wall 400 that adheres to the trousers 2, and the right connecting portion 41 has... There is a second inclined outer wall 410 attached to the pants 2. When the pants device 1 is worn on the human body, the left connecting part 40 and its first inclined outer wall 400, and the right connecting part 41 and its second inclined outer wall 410 are located between the two thigh roots of the human body; the first inclined outer wall 400 is located on the left side of the crotch opening 10, and the first inclined outer wall 400 is inclined from front to back and from right to left; the second inclined outer wall 410 is located on the right side of the crotch opening 10, and the second inclined outer wall 410 is inclined from front to back and from left to right. Based on this design, the first inclined outer wall 400 and the second inclined outer wall 410 form a figure-eight shape that is narrower in the front and wider in the back, which has a certain guiding effect on the connecting frame 4 to move forward. This facilitates the connecting frame 4 to enter the crotch area between the legs of the human body relatively easily. Even if the crotch area between the legs of some patients is relatively narrow, the left connecting part 40 of the first inclined outer wall 400, which is inclined from front to back and from right to left, and the right connecting part 41 of the second inclined outer wall 410, which is inclined from front to back and from left to right, can also be squeezed into the crotch area between the legs of the human body relatively easily. In summary, this design improves the ease of wearing the trouser covering device 1.

[0048] In this embodiment, the first inclined outer wall 400 and the second inclined outer wall 410 are symmetrical from left to right. The left connecting portion 40 and the right connecting portion 41 are also symmetrical from left to right. The trousers 2 are equipped with a leak-proof gasket 20 for contact with the human body. The leak-proof gasket 20 can be an inflatable gasket, a gel gasket, a latex gasket, a sponge gasket, etc. The leak-proof gasket 20 is used to ensure that the trousers 1 fits tightly against the human body after being worn, so that the excrement of the human body is difficult to leak out from between the leak-proof gasket 20 and the human body, thus achieving the purpose of preventing leakage. The leak-proof gasket 20 has a left extension section 200 for contact with the human body and a right extension section 201 for contact with the human body. The left extension section 200 and the right extension section 201 are located on the left and right sides of the crotch opening 10. The connecting frame 4 is located in the crotch of the trousers 1. When the trousers 1 is worn on the human body, the left extension section 200 and the right extension section 201 are located between the two thigh roots of the human body. The first inclined outer wall 400 is located on the back side of the left extension section 200, and the second inclined outer wall 410 is located on the back side of the right extension section 201. This arrangement, with the first inclined outer wall 400 on the dorsal side of the left extension segment 200 and the second inclined outer wall 410 on the dorsal side of the right extension segment 201 forming a V-shape that is narrower in the front and wider in the back, allows the left and right extension segments 200 and 201 to fit more smoothly between the groin and the groin of the human body, even if some patients have a relatively narrow space between their legs. The first inclined outer wall 400, which slopes from front to back and from right to left, facilitates the forward movement of the left extension segment 200. The second inclined outer wall 410, which slopes from front to back and from left to right, allows the right extension segment 201 to fit forward and to the right against the right groin area of ​​the human body. This facilitates a more complete fit between the left and right extension segments 200 and the groin area, improving the seal between the left and right extension segments 200 and the human body, reducing the likelihood of leakage of excrement from the left and right extension segments 200 and the human body, and also improving the comfort of wearing the garment to some extent.

[0049] The first inclined outer wall 400 and the second inclined outer wall 410 are attached to the trousers 2. Furthermore, the first inclined outer wall 400 is attached to the back 2000 of the left extension section 200, which helps maintain the shape of the left extension section 200 and prevents it from collapsing. The second inclined outer wall 410 is attached to the back 2010 of the right extension section 201, which also helps maintain the shape of the right extension section 201 and prevents it from collapsing. The leak-proof gasket 20 also has a U-shaped extension section 202 for contact with the human body. The left extension section 200, the U-shaped extension section 202, and the right extension section 201 are connected sequentially. The left extension section 200 extends downward from the left end of the U-shaped extension section 202, and the right extension section 201 extends downward from the right end of the U-shaped extension section 202. The trousers 2 also have an upper covering 21 corresponding to the abdomen and a lower covering 22 corresponding to the buttocks. The upper covering 21 and the lower covering 22 are respectively provided with straps 23 on the left and right sides. Each strap 23 is provided with Velcro. When the trousers 1 is worn on the body, the upper covering 21 and the lower covering 22 are tightly connected by the straps 23 and Velcro to achieve a tight wrap around the body.

[0050] The diaper trousers 2 also include a diaper cover 24, which is raised and has a first U-shaped edge 240 corresponding to the U-shaped extension 202. The first U-shaped edge 240 is attached to the back of the U-shaped extension 202 and is made of a flexible material. The first U-shaped edge 240 can be attached to the back of the U-shaped extension 202 using adhesive. The first U-shaped edge 240 can be made of flexible materials such as rubber or silicone. Because the U-shaped extension 202 adapts to the contours of the body when in contact with it, the flexible first U-shaped edge 240 more easily adapts and deforms along with the U-shaped extension 202, thus reducing resistance to the deformation of the U-shaped extension 202. This allows the U-shaped extension 202 to adapt more freely to the contours of the body, promoting a more complete fit between the U-shaped extension 202 and the body.

[0051] The connecting frame 4 also includes a first U-shaped portion 42 and a second U-shaped portion 43. The first U-shaped portion 42 is located at the lower front part of the connecting frame 4, and the second U-shaped portion 43 is located at the upper rear part of the connecting frame 4. A left connecting portion 40 and a right connecting portion 41 are respectively connected between the first U-shaped portion 42 and the second U-shaped portion 43. The first U-shaped portion 42, the left connecting portion 40, the second U-shaped portion 43, and the right connecting portion 41 are connected in sequence to form the crotch opening 10. The diaper cover 24 is located in front of the second U-shaped portion 43. The diaper cover 24 is made of flexible material, and its rear part is connected to the second U-shaped portion 43. The left connecting portion 40 extends downward from the left end of the second U-shaped portion 43, and the right connecting portion 41 extends downward from the right end of the second U-shaped portion 43. The first inclined outer wall 400 and the second inclined outer wall 410 are respectively connected between the first U-shaped portion 42 and the second U-shaped portion 43. The first inclined outer wall 400 extends downward from the left end of the second U-shaped portion 43, and the second inclined outer wall 410 extends downward from the right end of the second U-shaped portion 43. The upper surface of the first U-shaped portion 42 is pasted to the trousers 2. The first U-shaped portion 42 surrounds the front end of the crotch opening 10. The left connecting portion 40 and the right connecting portion 41 are respectively connected to the first U-shaped portion 42. The first inclined outer wall 400 and the second inclined outer wall 410 are respectively elongated strips extending upward.

[0052] The left extension 200 and the right extension 201 extend along the edge of the crotch opening 10, respectively. The first inclined outer wall 400 is located on the back side of the left extension 200 to provide back support for the left extension 200, and the second inclined outer wall 410 is located on the back side of the right extension 201 to provide back support for the right extension 201. This design helps to maintain the shape of the left extension 200 and the right extension 201, and even when the anti-leakage gasket 20 is an air gasket, its left extension 200 and right extension 201 are not easy to collapse. The first inclined outer wall 400, which slopes from front to back and from right to left, and the second inclined outer wall 410, which slopes from front to back and from left to right, can provide back support for the left extension 200 and the right extension 201, promoting the left extension 200 and the right extension 201 to fit together with the human crotch in a figure-eight pattern, and enabling the left extension 200 and the right extension 201 to fit together more fully with the human crotch.

[0053] The connecting frame 4 is provided with an air inlet 44, an air outlet 45, and an airflow channel. The airflow channel connects the air inlet 44 and the air outlet 45, so that the connecting frame 4 can form an air delivery channel. When the air pressure at the air outlet 45 is lower than the air pressure at the air inlet 44, air can flow through the air inlet 44, the airflow channel, and the air outlet 45 in sequence, thereby replenishing the air to the air outlet 45.

The left fastening part 403 and the right fastening part 413 can be a slot and / or a buckle protrusion, respectively. The left fastening part 403 and the right fastening part 413 are part of the second frame 481.

[0064] This patent application also provides a waste collection component, including a trouser cover device 1, a working head 5, and a connecting frame 4 for connecting the trouser cover device 1 and the working head 5. The working head 5 can be detachably connected to the connecting frame 4 to achieve connection with the trouser cover device 1. The working head 5 is indirectly worn on the human body by connecting to the trouser cover device 1. The working head 5 is provided with a trough 500 for receiving human excrement. When the trouser cover device 1 and the working head 5 are connected together, the connecting frame 4 fits against the working head 5 and is located between the working head 5 and the trouser cover 2.

[0065] The working head 5 can be forward-mounted to the connecting frame 4 for connection to the trouser-covering device 1. The working head 5 is also provided with a left snap fastener 51 for engaging with the left snap fastener 403 and a right snap fastener 52 for engaging with the right snap fastener 413. With this design, the trouser-covering device 1 can be quickly and easily connected to the working head 5 via the connecting frame 4. The left snap fastener 51 and the right snap fastener 52 are pivotally connected to the main body of the working head 5. The left snap fastener 51 and the right snap fastener 52 are respectively provided with mating parts for engaging with the left snap fastener 403 and the right snap fastener 413. The mating parts can be slots and / or snap protrusions. When in use, after the body is fully dressed in the trousers device 1, the working head 5 is aligned forward with the connecting frame 4. The left buckle member 51 of the working head 5 is fastened with the left fastening part 403, and the right buckle member 52 is fastened with the right fastening part 413, thereby connecting the trousers device 1 and the working head 5 together. When unlocking, press the left buckle member 51 and the right buckle member 52 in opposite directions with your hands, causing the left buckle member 51 to tilt to the left and the right buckle member 52 to tilt to the right. This causes the mating part of the left buckle member 51 to separate from the left fastening part 403 to the left and the mating part of the right buckle member 52 to separate from the right fastening part 413 to the right, thereby releasing the fastening. Then, the working head 5 can be separated from the trousers device 1 by moving backward.

[0066] The working head 5 also includes a spray nozzle 53 for spraying water and a front housing 50. The spray nozzle 53 is fixed to the front housing 50. The front housing 50 is recessed downward to form the latrine 500. The front housing 50 is a one-piece molded part. The front housing 50 also has a drain port 501 for discharging excrement from the latrine 500. The drain port 501 is located at the rear end of the latrine 500, and the spray nozzle 53 is located above the drain port 501. When the trouser-covering device 1 is connected to the working head 5, the connecting frame 4 is attached to the front housing 50 and located between the front housing 50 and the trouser-covering device 2. The front housing 50 may be made of plastic. The air outlet 45 is used to discharge air towards the latrine 500. When the trouser-wrapping device 1 is connected to the working head 5, the air outlet 45 is adjacent to the front end of the latrine 500 and located on the upper side of the front end of the latrine 500. This arrangement can effectively replenish the air to the latrine 500, promoting more thorough suction of the sewage collected in the latrine 500. When the trouser-wrapping device 1 is connected to the working head 5, the air inlet 44, the airflow channel, the air outlet 45, and the latrine 500 are connected in sequence. When the air pressure inside the latrine 500 is lower than the external air pressure of the sewage collection component, the connecting frame 4 is attached to the working head 5, and the external air of the sewage collection component flows sequentially through the air inlet 44, the airflow channel, and the air outlet 45 to the latrine 500 to replenish the air in the latrine 500.

[0067] The working head 5 can be connected to the connecting frame 4 to be connected to the trouser device 1. When the trouser device 1 is connected to the working head 5, the left connecting part 40 and the right connecting part 41 are respectively attached to the front housing 50 and located between the front housing 50 and the trouser device 1. When the trouser device 1 is connected to the working head 5, the diaper cover 24 of the trouser 2 is located above the toilet bowl 500 and the crotch opening 10 is connected to the toilet bowl 500 (so that human excrement enters the toilet bowl 500 through the crotch opening 10). The rear part of the diaper cover 24 is attached to the connecting frame 4.

[0068] This patent application also provides a nursing machine, including a panty-covering device 1, a working head 5, a main unit (not shown), and a suction pipe 60 connecting the working head 5 and the main unit. The main unit is equipped with a negative pressure source (not shown) that provides power for suctioning and discharging waste. The negative pressure source is equipped with a motor and an impeller fixed to the motor shaft. The impeller can rotate under the drive of the motor shaft to generate a suction effect to suck up waste from the commode 500. When the panty-covering device 1 is connected to the working head 5, the left connecting part 40 and the right connecting part 41 are respectively attached to the working head 5 and located between the working head 5 and the panty-covering device 2. The working head 5 is also equipped with a waste discharge port 54 for connecting to the suction pipe 60. The waste discharge port 54 is located on the rear side of the working head 5. Under the suction of the negative pressure source, the waste from the commode 500 is sequentially sucked into the main unit through the waste discharge port 501, the waste discharge port 54, and the suction pipe 60, and is further stored in the waste bin (not shown) of the main unit. Under the suction of the negative pressure source, the air pressure inside the toilet bowl 500 is lower than the air pressure outside the toilet collection component. As a result, the air outside the toilet collection component flows through the vent 241, filter screen 11, air inlet 44, airflow channel, and air outlet 45 in sequence to the toilet bowl 500, thereby replenishing the toilet bowl 500 with air and promoting more complete suction of the excrement inside the toilet bowl 500.
