[0001] This utility model relates to the field of medical and nursing equipment, and more specifically, it relates to a bathing machine for bedridden patients. Background Technology
[0002] Good hygiene is one of the basic physiological needs of human beings, and maintaining the cleanliness of patients' bodies is an important guarantee for ensuring individual comfort, safety and health. Patients admitted to the ICU are routinely placed under a no-family-accompanying policy, and basic patient care is an important part of the nursing work, entirely completed with the assistance of nurses.
[0003] Daily care for bedridden patients includes: 1. Patients who can sit up are pushed to the bathroom in a wheelchair, which is cumbersome and requires multiple people to assist. 2. Bedridden patients are given sponge baths or moved to a dedicated bathtub or bathing bed. Both methods carry risks of drowning and cross-infection, and require multiple people to assist. Bathing is especially unsuitable for areas with pressure sores or other wounds.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bathing machine for bedridden patients, which cleans the patient's skin by setting two rotating hemispherical brush heads in the bathing head, thereby achieving a rapid cleaning effect.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a bathing machine for bedridden patients, including a control box, a water storage tank and a collection and filter box electrically connected to the controller, the control box is provided with a connecting pipe communicating with the water storage tank and the collection and filter box, the connecting pipe is provided with a bathing head, the bathing head includes two rotating hemispherical brush heads, the two hemispherical brush heads form a sphere and rotate in opposite directions.
[0007] Preferably, the shower head includes a base, on which a rotating mounting rod is provided, and two hemispherical brush heads are rotatably mounted on the mounting rod. A drive motor is provided on the base, and the drive end of the drive motor is coaxially and fixedly connected to the mounting rod.
[0008] Preferably, the base is provided with an annular brush plate that fits against the hemispherical brush head. A first arc-shaped guide plate is provided on the side of the annular brush plate near the side wall of the base. A plurality of nozzles corresponding to the first arc-shaped guide plate are arranged in a ring on the side wall of the base. A second arc-shaped guide plate is provided on the side of the annular brush plate near the bottom of the base. A suction cup corresponding to the second arc-shaped guide plate is provided on the base. Both the first arc-shaped guide plate and the second arc-shaped guide plate fit against the hemispherical brush head.
[0009] Preferably, each of the two hemispherical brush heads is provided with a bevel gear at the end away from the mounting rod, the base is provided with a toothed ring that meshes with the bevel gear, and the end of the base is connected to a detachable fixing sleeve.
[0010] Preferably, the suction cup has a slot at its center, the connecting pipe has a first ventilation pipe connected to the slot and a second ventilation pipe corresponding to the suction cup, the control box has a first water pump connected to the first and second ventilation pipes, and the output end of the first water pump is connected to the collection filter box through a collection pipe.
[0011] Preferably, the control box is equipped with a second water pump, the input end of the second water pump is connected to the water storage tank through a connecting pipe, and the output end of the second water pump is connected to several nozzles through a transport pipe.
[0012] In summary, this utility model has the following beneficial effects:
[0013] 1) Start the drive motor through the control box, which in turn causes the drive motor to rotate the mounting rod. When the mounting rod rotates, it causes the two hemispherical brush heads to rotate radially along the shower head at the same time. When the two hemispherical brush heads are rotating, their bevel gears mesh with the gear ring on the base, causing the two hemispherical brush heads to rotate in opposite directions and their rotation surfaces to be perpendicular to the rotation surface of the mounting rod. This allows the two hemispherical brush heads to effectively clean the patient's skin when they come into contact with it.
[0014] 2) When the two hemispherical brush heads clean the patient's body, the dirt remaining on the hemispherical brush heads is initially cleaned by their own rotation and the ring brush plate.
[0015] 3) By starting the second water pump, water is drawn out of the water storage tank, and the water is transported through the transport pipe to several nozzles to spray water at a certain pressure. When the annular brush plate cleans the surface of the hemispherical brush head, the water sprayed at a certain pressure can clean the annular brush plate through the first arc-shaped guide plate. At the same time, because the first arc-shaped guide plate is in contact with the side wall of the hemispherical brush head, the nozzle can also provide enough water to the outer surface of the hemispherical brush head. Meanwhile, under the guidance of the first arc-shaped guide plate, the water will flow in an arc to the other side of the annular brush plate.
[0016] 4) When the water sprayed from the nozzles and the annular brush plate clean the two hemispherical brush heads, the first water pump is activated. This pump, through the first and second ventilation pipes, applies suction to the suction cups and slots. The first ventilation pipe and suction cup work together to remove the water with stains from the annular brush plate. Simultaneously, the second ventilation pipe removes excess water from the hemispherical brush heads through the slots, preventing excessive water from flowing onto the sheets through the patient's body. The second arc-shaped guide plate directs the water from the annular brush plate to the suction cups, facilitating the removal of soiled water. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0024] A type of bathing machine for bedridden patients, such as Figures 1 to 5 As shown, it includes a control box 1, a water storage tank 2 and a collection and filter box 3 electrically connected to the controller. The control box 1 is provided with a connecting pipe 4 that communicates with the water storage tank 2 and the collection and filter box 3. A shower head 5 is provided on the connecting pipe 4. The shower head 5 includes two rotating hemispherical brush heads 6. The two hemispherical brush heads 6 form a sphere and rotate in opposite directions.
[0025] In practical applications, the collection and filter box 3 can be equipped with medical water filtration equipment, which is an existing technology. Meanwhile, the control box 1 is equipped with a power cord that can be connected to a regular power socket.
[0026] The following is a further setting based on the above embodiments, such as... Figures 3 to 5 As shown, the shower head 5 also includes a base 7, on which a rotating mounting rod 8 is provided. Two hemispherical brush heads 6 are rotatably connected to the mounting rod 8. A drive motor 9 is fixedly mounted on the base 7, and the drive end of the drive motor 9 is coaxially and fixedly connected to the mounting rod 8. A bevel gear 15 is provided at the end of each of the two hemispherical brush heads 6 away from the mounting rod 8. A gear ring 16 that meshes with the bevel gear 15 is provided on the base 7. A detachable fixing sleeve 17 is connected to the end of the base 7. The drive motor 9 is electrically connected to the control box 1.
[0027] As described above, in practical applications, the drive motor 9 is started by the control box 1, which in turn causes the drive motor 9 to rotate the mounting rod 8. When the mounting rod 8 rotates, it causes the two hemispherical brush heads 6 to rotate radially along the shower head 5 at the same time. When the two hemispherical brush heads 6 are rotating, their bevel gear 15 meshes with the gear ring on the base 7, causing the two hemispherical brush heads 6 to rotate in opposite directions and their rotation surfaces to be perpendicular to the rotation surface of the mounting rod 8. This allows the two hemispherical brush heads 6 to effectively clean the patient's skin when they come into contact with the patient's skin.
[0028] The following is a further setting based on the above embodiments, such as... Figures 3 to 4 As shown, an annular brush plate 10 that fits against the hemispherical brush head 6 is provided on its base 7.
[0029] As described above, in practical applications, when the two hemispherical brush heads 6 clean the patient's body, the dirt remaining on the hemispherical brush heads 6 is initially cleaned by their own rotation and the annular brush plate 10 after the two hemispherical brush heads 6 clean the patient's body.
[0030] The following is a further setting based on the above embodiments, such as... Figures 3 to 4 As shown, the annular brush plate 10 is provided with a first arc-shaped guide plate 11 that fits against the sidewalls of the two hemispherical brush heads 6 on the sidewall of the base 7. A plurality of nozzles 12 corresponding to the first arc-shaped guide plate 11 are arranged in annular array on the sidewall of the base 7. A second water pump is provided in the control box 1. The input end of the second water pump is connected to the water storage tank 2 through a connecting pipe. The output end of the second water pump is connected to the plurality of nozzles 12 through a transport pipe. The second water pump is electrically connected to the control box 1.
[0031] As described above, in practical applications, the second water pump is activated to extract water from the water storage tank 2, allowing the water to be transported through the transport pipe to several nozzles 12 to spray water at a certain pressure. When the annular brush plate 10 cleans the surface of the hemispherical brush head 6, the water sprayed at a certain pressure can clean the annular brush plate 10 through the first arc-shaped guide plate 11. At the same time, because the first arc-shaped guide plate 11 is in contact with the side wall of the hemispherical brush head 6, the nozzles 12 can also provide sufficient moisture to the outer surface of the hemispherical brush head 6. Meanwhile, under the guidance of the first arc-shaped guide plate 11, the water will flow in an arc to the other side of the annular brush plate 10.
[0032] The following is a further setting based on the above embodiments, such as... Figures 3 to 4 As shown, the annular brush plate 10 is provided with a second arc-shaped guide plate 13 on the side near the bottom of the base 7, which fits against the sidewalls of the two hemispherical brush heads 6. The base 7 is provided with a suction cup 14 corresponding to the second arc-shaped guide plate 13. A slot 18 is opened at the center of the suction cup 14. The connecting pipe 4 is provided with a first ventilation pipe connected to the slot 18 and a second ventilation pipe corresponding to the suction cup 14. The control box 1 is provided with a first water pump connected to the first ventilation pipe and the second ventilation pipe. The output end of the first water pump is connected to the collection filter box 3 through a collection pipe. The first water pump is electrically connected to the control box 1.
[0033] As described above, in practical applications, when the water sprayed from the nozzle 12 cleans the two hemispherical brush heads 6 with the annular brush plate 10, the first water pump is activated. This pump, through the first and second ventilation pipes, applies suction to the suction cup 14 and the slot 18. The first ventilation pipe and suction cup 14 work together to remove the water with stains from the annular brush plate 10. Simultaneously, the second ventilation pipe removes excess water from the hemispherical brush heads 6 through the slot 18, preventing excessive water from flowing onto the bed sheet through the patient's body. The second arc-shaped guide plate 13 guides the water from the annular brush plate 10 to the suction cup 14, facilitating the removal of the water with stains.
[0034] In summary:
[0035] When a bedridden patient needs bathing, the drive motor 9, the first water pump, and the second water pump are activated via the control box 1. This causes the drive motor 9 to rotate the mounting rod 8, which in turn rotates the two hemispherical brush heads 6. Simultaneously, the bevel gears 15 on the two hemispherical brush heads 6 mesh with the gear ring on the base 7, causing the two hemispherical brush heads 6 to rotate in opposite directions with their rotation surfaces perpendicular to the rotation surface of the mounting rod 8. This allows the two hemispherical brush heads 6 to clean the patient's skin when the brush heads come into contact with it. As the two hemispherical brush heads 6 rotate, the annular brush plate 10 on the base 7 cleans the surfaces of the two hemispherical brush heads 6. Meanwhile, the second water pump delivers water from the water tank 2 to the nozzle 12 via a transport pipe, spraying water at a certain pressure. This allows the nozzle 12 to rinse the surfaces of the two hemispherical brush heads 6 and the annular brush plate 10 while simultaneously replenishing moisture. At the same time, the first water pump applies suction to the suction cup 14 and the slot 18 through the first and second ventilation pipes. This allows the first ventilation pipe and the suction cup 14 to work together to remove the water with stains that the nozzle 12 has cleaned from the annular brush plate 10. Meanwhile, the second ventilation pipe removes excess water from the hemispherical brush head 6 through the slot 18, thus preventing excessive water from flowing onto the bed sheet through the patient's body.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
