Description

Technical Field

[0001] This invention relates to the field of limb rehabilitation devices, and more particularly to an auxiliary rehabilitation device for ICU patients who are bedridden. Background Technology

[0002] Rehabilitation equipment mainly helps patients carry out passive movements and daily activities to promote rehabilitation. Most of them are made of stainless steel, iron, plastic, and wood. They are made into the required parts through machining, welding, injection molding and other production processes. Finally, several or hundreds of parts are assembled into rehabilitation equipment. The design is trending towards intelligence. Rehabilitation equipment can meet the patient's daily passive movement of the upper and lower limbs. Timed electric turning care beds can meet the daily turning needs. Electric wheelchairs can meet the needs of walking, standing and so on. Therapists use some equipment to perform passive movement or manual training on the patient's limb function. Patients can also use the equipment for self-training or training under the guidance of therapists.

[0003] However, existing rehabilitation exercise devices still have many shortcomings and are difficult to adapt to the special needs of ICU patients: First, most devices require patients to actively exert force to complete the exercise, but ICU patients are weak and often unable to carry out rehabilitation training independently, making it difficult to achieve the expected rehabilitation effect; Second, existing devices are generally large in size, occupy a lot of space, and have limited applicable scenarios, making them difficult to install conveniently on hospital beds and unable to provide targeted automatic rehabilitation exercises for the limbs of bedridden patients; Third, existing exercise assistive devices have relatively simple functions, mostly only able to achieve rehabilitation training for a single part, and cannot take into account the diverse passive rehabilitation needs of ICU patients with multiple parts. Therefore, we propose an auxiliary rehabilitation device for ICU patients with severe illness. Summary of the Invention

[0004] Purpose of the Invention: The purpose of this invention is to provide an auxiliary rehabilitation device for ICU bedridden patients, solving the problem that existing rehabilitation exercise devices rely on the patient's active exertion and cannot be adapted to the needs of frail ICU patients. This device enables automatic passive limb rehabilitation training without the patient's active participation, ensuring effective rehabilitation. Another purpose of this invention is to provide a compact auxiliary rehabilitation device that can be easily installed on a hospital bed, expanding its applicability. It integrates rehabilitation functions for multiple body parts, taking into account the diverse passive rehabilitation needs of ICU bedridden patients in various areas, including the upper and lower limbs. This overcomes the shortcomings of existing devices, which have limited functionality and applicability, providing efficient, convenient, and comprehensive rehabilitation support for ICU bedridden patients.

[0005] Technical solution: An auxiliary rehabilitation device for ICU bedridden patients, including a drive mechanism, with an arm fixation mechanism disposed above the drive mechanism;

[0029] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figures 1-5 As shown, an auxiliary rehabilitation device for ICU bedridden patients is provided, including a drive mechanism 1;

[0032] The drive mechanism 1 includes a guide seat 101, an L-shaped bracket 102 is fixedly connected to the right side of the guide seat 101, a motor 103 is fixedly connected to the inner side of the L-shaped bracket 102, a reciprocating screw 104 is fixedly connected to the left end of the output shaft of the motor 103 located inside the guide seat 101, and a screw sleeve 105 is threadedly installed on the outer side wall of the reciprocating screw 104.

[0033] A shaft seat 106 is fixedly connected to the right side of the front surface of the guide seat 101. A shaft column 107 is rotatably connected to the inner side of the shaft seat 106 via a rotating shaft. A gear 108 is fixedly connected to the right end of the shaft column 107. A gear 109 is fixedly connected to the outer wall of the output shaft of the litigation motor 103. The outer walls of the gear 108 and the outer walls of the gear 109 mesh with each other. A cylinder 110 is fixedly connected to the left end of the shaft column 107. A cam groove 111 is provided on the outer wall of the cylinder 110.

[0034] A hydraulic tank 112 is fixedly connected to the front surface of the guide seat 101 and to the left of the cylinder 110. A connecting pipe 113 is fixedly connected to the left side of the hydraulic tank 112. A piston plate 114 is slidably connected to the inner side of the hydraulic tank 112. A connecting plate 115 is fixedly connected to the right side of the piston plate 114. A connecting column 116 is fixedly connected to the rear surface of the connecting plate 115 and to the inner side of the cam groove 111.

[0035] When the drive mechanism 1 is in use, the motor 103 is started first. The output shaft of the motor 103 drives the reciprocating lead screw 104 and the second gear 109 to rotate synchronously. When the reciprocating lead screw 104 rotates, it drives the lead screw sleeve 105 to move horizontally back and forth along the guide seat 101, providing horizontal driving force for the arm fixation mechanism 2. At the same time, the second gear 109 drives the meshing gear 108 to rotate. The gear 108 drives the cylinder 110 to rotate through the shaft column 107. When the cylinder 110 rotates, the cam groove 111 on its outer side pushes the connecting column 116 to move left and right back and forth. The connecting column 116 drives the piston plate 114 to slide left and right inside the hydraulic tank 112 through the connecting plate 115, and then realizes the filling and releasing of the hydraulic bladder 211 through the connecting pipe 113, providing power for the passive rehabilitation of the fingers. The entire drive mechanism 1 can provide driving force for the rehabilitation of the arm and fingers synchronously without the patient having to exert force actively.

[0036] like Figure 6 and Figure 7 As shown, an arm fixing mechanism 2 is provided above the drive mechanism 1;

[0037] The arm fixing mechanism 2 includes a placement seat 201. The bottom of the placement seat 201 is fixedly connected to the top of the lead screw sleeve 105. A through groove 202 is provided on the front surface of the placement seat 201. A strap 203 is fixedly connected to the rear of the upper surface of the placement seat 201. The front end of the strap 203 extends to the inside of the through groove 202. A pressure plate 204 is provided inside the through groove 202 and above the strap 203. Two vertical rods 205 are fixedly connected to the upper surface of the pressure plate 204. The top ends of the vertical rods 205 extend through to the top of the placement seat 201 and are fixedly connected to a pull bar 206.

[0038] Spring 207 is fixedly connected to the opposite sides of the placement seat 201 and the pull bar 206, and located on the outside of the two vertical bars 205.

[0039] Anti-slip strips 208 are provided on the opposite sides of the pressure plate 204 and the strap 203;

[0040] A mounting plate 209 is fixedly connected to the right side of the placement seat 201. A column 210 is fixedly connected to the upper surface of the mounting plate 209. A hydraulic bladder 211 is sleeved on the outer side wall of the column 210. The interior of the hydraulic bladder 211 is connected to the end of the connecting pipe 113 away from the hydraulic tank 112. Multiple finger sleeves 212 are fixedly connected to the outer side wall of the hydraulic bladder 211.

[0041] When using the arm fixation mechanism 2, first pull the pull bar 206 upward. The pull bar 206 drives the pressure plate 204 upward through the vertical rod 205 and compresses the spring 207. At this time, place the arm of the ICU critically ill bedridden patient on the placement seat 201. Release the pull bar 206, and the spring 207 resets and pushes the pressure plate 204 downward. With the help of the strap 203, the arm is clamped and fixed. The anti-slip strip 208 can prevent the arm from sliding. Then, put the patient's fingers into the corresponding finger sleeves 212. When the drive mechanism 1 works, the connecting pipe 113 fills and releases fluid into the hydraulic bladder 211. The expansion and contraction of the hydraulic bladder 211 drives the fingers to bend and extend, realizing passive rehabilitation training of the fingers. At the same time, the screw sleeve 105 drives the placement seat 201 to move horizontally back and forth, realizing passive rehabilitation training of the arm in the horizontal direction.

[0042] like Figure 2 and Figure 3 As shown, a clamping mechanism 3 is provided below the drive mechanism 1;

[0043] The clamping mechanism 3 includes a screw 301. The top end of the screw 301 is rotatably connected to the front of the lower surface of the guide seat 101 via a rotating shaft. A clamping plate 302 is threadedly connected to the outer wall of the screw 301. Two guide rods 303 are provided on the front of the lower surface of the clamping plate 302. The top end of the guide rod 303 passes through the clamping plate 302 and is fixedly connected to the lower surface of the guide seat 101.

[0044] A knob 304 is fixedly connected to the bottom end of the screw 301;

[0045] Multiple rubber strips 305 are provided on opposite sides of the clamping plate 302 and the guide seat 101;

[0046] The clamping mechanism 3 is used to fix the entire device to the hospital bed. When in use, first align the lower surface of the guide seat 101 with the edge of the hospital bed so that the edge of the hospital bed is between the guide seat 101 and the clamping plate 302. Then turn the knob 304. The knob 304 drives the screw 301 to rotate. Due to the limiting effect of the guide rod 303 on the clamping plate 302, the screw 301 rotates and drives the clamping plate 302 to move upward until the clamping plate 302 and the guide seat 101 cooperate to clamp and fix the device to the hospital bed. The rubber strip 305 can increase the friction to prevent the device from sliding and avoid pinching the hospital bed.

[0047] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
