Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an electric dialysis chair. Background Technology

[0002] Dialysis used in medicine is broadly classified into three categories: hemodialysis, peritoneal dialysis, and colonic dialysis. Hemodialysis, also known as hemodialysis or artificial kidney, is a blood purification technology. A medical dialysis chair, also called an electric dialysis chair, is a medical device mainly composed of a medical PU leather seat, a motor, and a control system. It is used in hospital dialysis rooms and other similar facilities. Generally, each dialysis session lasts about four hours, but this can be adjusted based on individual circumstances. The time required varies from person to person, and the effectiveness also differs. Some people may need to extend the treatment time to achieve the desired results. The risk of infection increases in the dialysis room, and caregivers are generally not allowed to enter the dialysis room during treatment.

[0003] According to the existing technology "A Dialysis Chair for Pediatric Use", published under the number "CN110882125A", this technology replaces the support plate with a medical toilet for children and controls the electric telescopic rod to lift the medical toilet into the oval-shaped opening on the seat for easy use.

[0004] During the several hours of dialysis treatment, some elderly patients need to defecate. Because the patients' limbs need to cooperate with the treatment and they cannot make large movements, some elderly patients have difficulty communicating with medical staff of the opposite sex. As a result, when preparing to defecate, they are still in a lying position and find it difficult to defecate, which affects the patient's experience. Summary of the Invention

[0005] The purpose of this invention is to provide an electric dialysis chair to solve the above-mentioned problems, thereby improving the situation where patients' limbs need to cooperate with the treatment and cannot make large movements during the treatment process, and some elderly patients have an inconvenience in communicating with medical staff of the opposite sex, which makes it difficult for them to defecate while still lying down, thus affecting the patient's user experience.

[0006] The present invention achieves the above-mentioned objectives through the following technical solution: an electric dialysis chair, comprising: a base, a servo motor embedded in the upper end of the base, two slides formed on the surface of the base, a threaded shaft rotatably connected to the inner wall of one slide, the threaded shaft being fixedly connected to the output shaft of the servo motor; a support mechanism, mounted above the base, the lower end of the support mechanism extending into the interior of the slides, the surface of the support mechanism being connected to the surface of the threaded shaft; wherein, the support mechanism includes a support adjustment assembly mounted above the base, a commode bowl mounted on the surface of the base is disposed below the middle of the support adjustment assembly, a preliminary cleaning assembly is disposed inside the support adjustment assembly, and an auxiliary garment removal assembly is disposed on the surface of the support adjustment assembly; the support adjustment assembly is used to reduce patient movement during defecation, the preliminary cleaning assembly is used to flush the commode bowl when the support adjustment assembly reciprocates, and the auxiliary garment removal assembly is used to assist the patient in preparing for defecation.

[0007] Preferably, the supporting and adjusting assembly includes two fixed frames fixedly connected to the upper end of the base, a support frame fixedly connected between the two fixed frames, a movable stop block slidably connected to the inner side of the support frame, a movable stop block slidably connected to the lower end of the movable stop block, and side sliders fixedly connected to both sides of the movable stop block. A guide plate slidably connected to the inner wall of the slide is fixedly connected to the inner side of the side slider, and the inner wall of one side of the guide plate is threadedly connected to the surface of the threaded shaft. The protrusion of the movable stop block matches the recess of the support frame. Simultaneously, the movable stop block can be constructed with a rigid material inside, and its surface can be coated with a flexible, deformable colloid, so that when the movable stop block and the support frame cooperate, it can provide an auxiliary sealing effect.

[0008] Preferably, the preliminary cleaning assembly includes a positioning block fixedly connected to the surface of the mounting frame and an internal groove formed inside the side slider. An air guide pipe is fixedly connected inside the positioning block, and a piston is fixedly connected to the other end of the air guide pipe. The piston is slidably connected to the inner wall of the internal groove, and the upper end of the air guide pipe is connected to a water storage tank. Movement of the piston causes gas inside the internal groove to be injected into the water storage tank through the air guide pipe, thereby increasing the pressure inside the water storage tank and discharging the stored liquid, thus performing a preliminary flushing of the toilet bowl.

[0009] Preferably, the auxiliary garment removal assembly includes a sliding groove formed at the upper end of the fixed frame. A sliding strip is slidably connected to the inner wall of the sliding groove. A fixed vertical rod is fixedly connected to the upper end of the sliding strip. A collar is fitted onto the surface of the fixed vertical rod. A fixed adjusting plate is fixedly connected to the surface of the collar. A vertical clamping strip is fixedly connected to one side of the fixed adjusting plate. The sliding strip is trapezoidal and matches the sliding groove, which can reduce the possibility of the sliding strip falling off. At the same time, the collar is fitted onto the surface of the fixed vertical rod. The internal cavity cross-section of the collar is larger than the solid cross-section of the fixed vertical rod, allowing the collar to have a certain range of motion. This range of motion ensures space for adjustment for patients with different waist sizes.

[0010] Preferably, the support frame is hinged to a backrest on the side near the movable abutment. A side armrest is hinged to the upper end of the backrest, and a hinge frame is hinged to the lower end of the side armrest. A fixed shaft is fixedly connected to the side of the hinge frame away from the backrest, and a footrest is fixedly connected to the surface of the fixed shaft. As the frame moves upwards, the fixed shaft rotates synchronously under the action of the hinge frame. This rotation of the fixed shaft then moves the footrest, allowing the patient's torso to be upright while lowering their legs, facilitating physiological defecation.

[0011] Preferably, the preliminary cleaning assembly further includes an embedded compartment within the support frame and the fixing frame. The water storage tank is located inside an adjacent embedded compartment. An internal pipe communicating with the water storage tank is located inside the embedded compartment. A spray head is connected to the lower end of the internal pipe, and the lower end of the spray head extends through to the outside of the support frame. A wedge-shaped surface is formed below the inner recess of the support frame. The water outlet of the spray head extends through the wedge-shaped surface, spraying water onto the inclined surface of the toilet bowl for flushing. The water jet from the spray head can automatically perform preliminary cleaning of the toilet bowl.

[0012] Preferably, the lower end of the support backrest is hinged with an arc-shaped abutment, and the other end of the arc-shaped abutment is hinged to the upper inclined surface of the movable abutment block. When the movable abutment block moves in the direction of the servo motor, it will drive the arc-shaped abutment to move synchronously. When the arc-shaped abutment moves, it will abut against the support backrest to move. Since the support backrest is hinged to the surface of the support frame, the support backrest will change from an approximately horizontal state to a more vertical state.

[0013] Preferably, a one-way air valve is fixedly connected to the inner wall of the internal groove, with one end of the one-way air valve extending to the outside of the side slider. As the side slider moves, it will drive the one-way air valve to move accordingly. At this time, with the cooperation of the piston, the one-way air valve will draw outside air into the interior of the internal groove.

[0014] Preferably, a fixed cylinder is fixedly connected to the end of the fixed adjusting plate. A rotating ring is rotatably connected to the surface of the fixed cylinder, and an arc-shaped clamp is fixedly connected to the surface of the rotating ring. The inner side of the arc-shaped clamp contacts the surface of the vertical clamping strip. The rotating ring rotates on the surface of the fixed cylinder, which in turn causes the fixed cylinder to move the arc-shaped clamp, allowing the clothing to be placed between the arc-shaped clamp and the vertical clamp, thus clamping the patient's clothing.

[0015] Preferably, a spring sheet is fixedly connected to the side of the fixed adjustment plate away from the vertical clamping strip, and an operating plate is fixedly connected to the surface of the spring sheet. The end of the operating plate is fixedly connected to the surface of the rotating ring. Pressing the operating plate compresses the spring sheet, and at the same time, the operating plate will drive the rotating ring to rotate on the surface of the fixed cylinder. At this time, the fixed cylinder will drive the arc-shaped clamping plate to move, so that the clothes can be placed between the arc-shaped clamping plate and the vertical clamping strip.

[0016] The beneficial effects of this invention are:

[0017] 1. During use, the support and adjustment components assist patients in adjusting their posture when preparing for defecation, improving the patient's experience during treatment. During treatment, patients' limbs need to cooperate with the therapy, limiting large movements and making defecation difficult while lying down, impacting the user experience. This device, through the cooperation of movable blocks and a support frame, ensures the patient can defecate during treatment. Simultaneously, the support backrest, curved support rod, and movable blocks provide support for the patient's torso. Furthermore, the side handrails, hinged frame, fixed axis, and footrest keep the patient's legs in a naturally drooping position. This assists elderly patients in adjusting their posture when needing to defecate, improving their overall experience.

[0018] 2. During use, the preliminary cleaning component allows the patient to complete defecation. After defecation, the adjustment component is reset and moved, which will cause the preliminary cleaning component to move accordingly. Then, through the cooperation of the internal groove and piston, external gas is injected into the water tank through the air tube. The internal tube will spray the liquid at the bottom of the water tank through the spray head to flush the toilet bowl, assisting in cleaning the toilet bowl.

[0019] 3. When in use, the auxiliary clothing removal component can assist patients in preparing for defecation when they have difficulty removing their clothes with one hand. The side support plate moves the fixed vertical rod synchronously. When the fixed vertical rod moves, it causes the sliding strip to slide on the inner wall of the sliding groove. At this time, the collar drives the fixed adjustment plate to move synchronously. The arc-shaped clamp at the end of the fixed adjustment plate cooperates with the vertical clamp to help the patient remove their clothes. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In practical implementation: such as Figure 1-10 As shown, an electric dialysis chair includes: a base 1, a servo motor 2 embedded in the upper end of the base 1, two slides 11 formed on the surface of the base 1, a threaded shaft 21 rotatably connected to the inner wall of one slide 11, and the threaded shaft 21 fixedly connected to the output shaft of the servo motor 2; and a support mechanism 3, which is installed above the base 1, with the lower end of the support mechanism 3 extending into the interior of the slide 11, and the surface of the support mechanism 3 connected to the surface of the threaded shaft 21.

[0033] The support mechanism 3 includes a support adjustment component 31 installed on the base 1. A urinal is installed on the surface of the base 1 and located below the center of the support adjustment component 31. A preliminary cleaning component 32 is installed inside the support adjustment component 31, and an auxiliary clothing removal component 33 is installed on the surface of the support adjustment component 31. The support adjustment component 31 is used to reduce the movement of the patient during defecation. The preliminary cleaning component 32 is used to flush the urinal when the support adjustment component 31 performs reciprocating movements. The auxiliary clothing removal component 33 is used to assist the patient in preparing for defecation. When the patient needs to defecate, the servo motor 2 can be driven to work. At this time, the output shaft of the servo motor 2 will drive the threaded shaft 21 to rotate synchronously. When the threaded shaft 21 rotates, it will drive the support adjustment component 31 to follow and move synchronously. Thus, when the support adjustment component 31 is in motion, it can assist the patient in adjusting from a lying position to a sitting position.

[0034] Simultaneously, when the support and adjustment component 31 is in motion, the urinal can be exposed for use, allowing the patient to defecate directly. When the support and adjustment component 31 is in motion, it will drive the preliminary cleaning component 32 to follow suit, thereby providing an auxiliary flushing effect on the urinal. The urinal can be connected to a sewer, or a sealed temporary storage box can be installed inside the base 1 to process the patient's excrement. When some elderly patients lose the ability to remove their clothes during treatment, the support and adjustment component 31 can drive the auxiliary clothing removal component 33 to help the patient remove their pants and assist in defecation.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 As shown, the support and adjustment assembly 31 includes two fixed brackets 311 fixedly connected to the upper end of the base 1. A support bracket 312 is fixedly connected between the two fixed brackets 311. A movable stop block 314 is slidably connected to the inner side of the support bracket 312. A movable stop block 313 slidably connected to the upper end of the base 1 is fixedly connected to the lower end of the movable stop block 314. Side sliders 315 are fixedly connected to both sides of the movable stop block 313. A guide plate 316 slidably connected to the inner wall of the slide rail 11 is fixedly connected to the inner side of the side slider 315. The inner wall of one guide plate 316 is connected to the threaded shaft 21. The support frame 312 is hinged to a support backrest 317 on the side near the movable abutment 314. The upper end of the support backrest 317 is hinged to a side hand plate 319. The lower end of the side hand plate 319 is hinged to a hinge frame 3110. A fixed shaft 3111 is fixedly connected to the side of the hinge frame 3110 away from the support backrest 317. A foot support plate 3112 is fixedly connected to the surface of the fixed shaft 3111. An arc-shaped abutment 318 is hinged to the lower end of the support backrest 317. The other end of the arc-shaped abutment 318 is hinged to the upper inclined surface of the movable abutment 313.

[0036] When the patient needs to use it, the servo motor 2 drives the threaded shaft 21 to rotate inside the slide 11. At this time, the guide plate 316, which is threaded to the surface of the threaded shaft 21, will move along the inner wall of the slide 11. When the guide plate 316 moves, the moving block 313 will move synchronously. In turn, the moving block 314 will move synchronously during the synchronous movement of the moving block 313. The protrusion of the moving block 314 matches the recess of the support frame 312. The structure of the moving block 314 can be made of rigid material inside and wrapped with flexible deformable colloid on its surface, so that when the moving block 314 and the support frame 312 are in contact, it can play an auxiliary sealing role.

[0037] When the movable abutment 313 moves toward the servo motor 2, it will drive the arc-shaped abutment 318 to move synchronously. When the arc-shaped abutment 318 moves, it will abut the support backrest 317 to move. Since the support backrest 317 is hinged to the surface of the support frame 312, the support backrest 317 will change from an approximately horizontal state to a more vertical state. {The upper end of the support backrest 317 is provided with a soft pad, and the hinge between the support frame 312 and the support backrest 317 is also provided with a protective pad. This protective pad is used in conjunction with medical sheets and mattresses, etc., and can be adjusted in height according to the patient's own needs, while avoiding the patient's body being pinched by the hinge, thus improving the patient's comfort.} As a result, the patient's torso will gradually become upright under the support of the support backrest 317, assisting elderly patients in adjusting their posture.

[0038] When the backrest 317 is supported, the side armrest 319 hinged at its upper end will follow suit. This will cause the horizontal height of the side armrest 319 to gradually rise with the help of the hinge frame 3110. At this time, the fixed shaft 3111 will rotate synchronously with the hinge frame 3110. Then, the movement of the fixed shaft 3111 will drive the footrest 3112 to move, so that the patient's torso is upright while the patient's legs are lowered, making it easier for the patient to defecate.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, the preliminary cleaning component 32 includes a positioning block 321 fixedly connected to the surface of the fixing frame 311 and an internal groove 322 opened inside the side slider 315. An air guide pipe 323 is fixedly connected inside the positioning block 321, and a piston 324 is fixedly connected to the other end of the air guide pipe 323. The piston 324 is slidably connected to the inner wall of the internal groove 322. The upper end of the air guide pipe 323 is connected to a water storage tank 325. The preliminary cleaning component 32 also includes an embedded compartment 326 opened inside the support frame 312 and the fixing frame 311. The water storage tank 325 is disposed inside the adjacent embedded compartment 326, and the embedded compartment 326 is provided with an internal compartment that communicates with the water storage tank 325. The lower end of the inner tube 327 is connected to a water nozzle 328, and the lower end of the water nozzle 328 extends to the outside of the support frame 312. A one-way air valve 329 is fixedly connected to the inner wall of the inner groove 322. One end of the one-way air valve 329 extends to the outside of the side slider 315. When the patient is ready to use it, the support adjustment component 31 is activated. At this time, the side slider 315 will move towards the servo motor 2 under the drive of the guide plate 316. As the side slider 315 moves, it will drive the one-way air valve 329 to move accordingly. At this time, with the cooperation of the piston 324, the one-way air valve 329 will draw the outside air into the interior of the inner groove 322.

[0040] When the patient finishes using the device, the servo motor 2 will restart, driving the side slider 315 to reset via the guide plate 316. Since the positioning block 321 is fixedly connected to the surface of the fixing frame 311, the air duct 323 will not move. At this time, the one-way valve 329 will prevent the gas inside the internal groove 322 from being discharged to the outside. Simultaneously, the gas inside the internal groove 322 will be forced into the air duct 323 by the piston 324, and then introduced into the water tank 3 through the conduit connected to the upper end of the air duct 323. Inside the tank 325, the water tank contains liquid, and the liquid level is lower than the highest point of the conduit. As gas enters, the pressure inside the water tank 325 will increase, and the liquid inside the water tank 325 will be discharged to the outside through the internal pipe 327 connected to it. Since the lower end of the internal pipe 327 is connected to multiple spray heads 328, {a wedge-shaped surface is provided below the inner recess of the support frame 312, and the water outlet of the spray head 328 passes through the wedge-shaped surface to spray water onto the inclined surface of the toilet bowl for flushing}, the water jet from the spray head 328 can automatically perform preliminary cleaning of the toilet bowl.

[0041] The auxiliary garment removal assembly 33 includes a sliding groove 331 formed at the upper end of the fixed frame 311. A sliding strip 332 is slidably connected to the inner wall of the sliding groove 331. A fixed vertical rod 333 is fixedly connected to the upper end of the sliding strip 332. A collar 334 is sleeved on the surface of the fixed vertical rod 333. A fixed adjusting plate 335 is fixedly connected to the surface of the collar 334. A vertical clamping strip 339 is fixedly connected to one side of the fixed adjusting plate 335. A fixed cylinder 336 is fixedly connected to the end of the fixed adjusting plate 335. A rotating ring 337 is rotatably connected to the surface of the fixed cylinder 336. An arc-shaped clamping plate 338 is fixedly connected to the surface of the rotating ring 337. The inner side of the arc-shaped clamping plate 338 contacts the surface of the vertical clamping strip 339. The fixed adjusting plate 335 is located away from the vertical clamping strip 339. A spring clip 3311 is fixedly connected to the side, and an operating plate 3310 is fixedly connected to the surface of the spring clip 3311. The end of the operating plate 3310 is fixedly connected to the surface of the rotating ring 337. When an elderly patient is unable to make large-scale movements of their limbs during treatment, or when their physical function is unable to meet the requirement of removing their pants with one hand to defecate, the auxiliary clothing removal component 33 can be connected to the elderly patient's most intimate clothing. When in use, the end of the arc-shaped clamp 338 is used in conjunction with the vertical clamp 339 to clamp the patient's clothing. This setting can enhance the clamping of the patient's clothing. At the same time, the arc-shaped clamp 338 is arc-shaped, which can reduce the friction with the patient's skin. When in use, the patient needs to cooperate to reduce the force on the buttocks against the clothing, which can assist the patient in preparing for defecation.

[0042] Since the sliding strip 332 is trapezoidal and matches the sliding groove 331, the possibility of the sliding strip 332 falling off can be reduced. At the same time, the collar 334 is sleeved on the surface of the fixed vertical rod 333. The internal cavity cross section of the collar 334 is larger than the solid cross section of the fixed vertical rod 333, so that the collar 334 can have a certain range of motion. This range of motion ensures the space for adjustment for patients with different waist sizes. When connecting with the patient's clothing, pressing the operating plate 3310 causes the spring piece 3311 to be squeezed. At the same time, the operating plate 3310 will drive the rotating ring 337 to rotate on the surface of the fixed cylinder 336. At this time, the fixed cylinder 336 will drive the arc-shaped clamp 338 to move, so that the clothes can be placed between the arc-shaped clamp 338 and the vertical clamp 339. Releasing the pressure on the operating plate 3310 will cause it to reset under the action of the spring piece 3311, so that the arc-shaped clamp 338 and the vertical clamp 339 clamp the patient's clothing.

[0043] When the patient is preparing to defecate, the support and adjustment component 31 assists the patient in changing their lying position. At this time, the side support plate 319 drives the fixed vertical rod 333 to move synchronously. {The upper end of the fixed vertical rod 333 is always above the side support plate 319}. When the fixed vertical rod 333 moves, it will drive the sliding strip 332 to slide on the inner wall of the sliding groove 331. At this time, the collar 334 will drive the fixed adjustment plate 335 to move synchronously. Then, the arc-shaped clamp 338 at the end of the fixed adjustment plate 335 will cooperate with the vertical clamp 339 to pull the patient's clothes off. During this operation, the patient needs to cooperate to reduce the positioning pressure on the buttocks and cooperate with the device to remove the clothes.

[0044] In use, the patient lies on top of the support mechanism 3 during treatment. By pressing the operating plate 3310, the patient's spring 3311 is compressed. The operating plate 3310 drives the rotating ring 337 to rotate on the surface of the fixed cylinder 336. The fixed cylinder 336 moves the arc-shaped clamp 338, and the patient's clothes are placed between the arc-shaped clamp 338 and the vertical clamp 339. Releasing the pressing of the operating plate 3310 resets the spring 3311, causing the arc-shaped clamp 338 to clamp the patient's clothes in conjunction with the vertical clamp 339. When defecation is required, the servo motor 2 drives the threaded shaft 21 to rotate. The guide plate 316, which is threaded to the threaded shaft 21, moves along the inner wall of the slide 11. When the guide plate 316 moves the side slider 315, the one-way valve 329 moves accordingly. In conjunction with the piston 324, the one-way valve 329 draws in external air. Inside the groove 322, the guide plate 316 drives the movable block 314 to move synchronously through the movable block 313. When the movable block 313 moves, it abuts the backrest 317 through the arc-shaped rod 318, supporting the patient's torso to gradually become upright. The backrest 317 drives the hinged side support plate 319 on it to follow the movement. The side support plate 319 drives the fixed vertical rod 333 to move synchronously. When the fixed vertical rod 333 moves, it drives the sliding strip 332 to slide on the inner wall of the sliding groove 331. At this time, the fixed adjustment plate 335 moves synchronously through the collar 334. The arc-shaped clamp 338 at the end of the fixed adjustment plate 335 cooperates with the vertical clamp 339 to help the patient take off their clothes. The side support plate 319, through the cooperation of the hinge frame 3110, causes the fixed shaft 3111 to follow the movement and drive the foot support plate 3112 to move.

[0045] When the patient finishes defecating, the servo motor 2 is restarted. The guide plate 316 drives the side slider 315 to reset and move. The positioning block 321 is fixedly connected to the surface of the fixing frame 311, so that the relative position of the air guide tube 323 remains unchanged with the positioning block 321. The gas inside the internal groove 322 is squeezed into the air guide tube 323 by the piston 324. The tube connected to the upper end of the air guide tube 323 guides the gas into the interior of the water tank 325. As the gas enters, the pressure inside the water tank 325 increases. The liquid inside the water tank 325 is introduced into the internal pipe 327 connected to it and sprayed out through the spray head 328, automatically performing a preliminary cleaning of the toilet bowl.

[0046] It should be noted that the servo motor 2 and other components mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. At the same time, the servo motor 2 can be powered by an internal power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
