Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a moving device for bedridden patients. Background Art

[0002] At present, in order to enable critically ill patients who have been bedridden for a long time to sit up conveniently, the bed board of the head part of the bed is usually designed to be an upwardly flip-up structure. As the bed board of the head part of the bed flips up, the patient also sits up accordingly. However, after the patient sits up, the flipped-up bed board will apply a forward force to the patient, causing the patient to have a tendency to slide downward (towards the foot of the bed). For ordinary patients, they can master their balance by themselves and avoid sliding. However, for critically ill patients, due to their poor physical strength and weak self-regulation ability, if the friction force at the sitting position is not large enough, they are very likely to slide down once they sit up. After sliding down, they often need the assistance of medical staff to move back to the original position. If the moving method is incorrect, it is easy to damage the patient's waist, and it is time-consuming and laborious, increasing the workload of medical staff. Summary of the Invention

Detailed implementation manners

[0021] The core of the present invention is to provide a mobile device for bedridden patients, which can lift the patient and assist medical staff to move the patient back to the original place. In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0022] As Figures 1 to 5 shown, the mobile device for bedridden patients in this embodiment includes two guide rails 100 and two lifting mechanisms 200; the two guide rails 100 are respectively used to be fixed on both sides of the hospital bed; the lifting mechanism 200 includes two moving frames 210, a lifting device 220, and a support pad 230; the bottoms of the two moving frames 210 are respectively slidably connected to the two guide rails 100, and a cross beam 240 spanning above the hospital bed is provided between the tops of the two moving frames 210; the lifting device 220 is installed on the cross beam 240; the support pad 230 is arranged below the cross beam 240, and both ends thereof are suspended at the output ends of the lifting device 220; the support pads 230 of the two lifting mechanisms 200 are respectively used to lift the upper and lower parts of the patient's torso. When in use, the support pads 230 of the two lifting mechanisms 200 are respectively padded on the shoulder and back and the buttocks, the support pad 230 is lifted by the lifting device 220 to lift the patient, and then the moving frame 210 is slid along the guide rail 100 to move the sliding patient back to the original place.

[0023] Among them, the lifting device 220 includes two electric hoists, the two electric hoists are respectively fixedly installed at both ends of the cross beam 240, and both ends of the support pad 230 are respectively hung on the hooks of the two electric hoists. A sleeve 221 is fixed on the top of the electric hoist, and the sleeve 221 is slidably sleeved on the cross beam 240 to facilitate the adjustment of the position of the electric hoist. Screws can be provided on the sleeve 221, and the electric hoist can be prevented from shifting after being tightened.

[0024] It should be noted that the above electric hoist is a common special lifting equipment, mainly composed of a motor, a transmission mechanism, a chain, a sprocket, etc. It has the characteristics of small volume, light self-weight, simple operation and convenient use. When using the electric hoist, the sprocket is rotated by the motor, and the lifting or releasing of the object suspended by the chain is realized by controlling the winding and unwinding of the chain wound on the groove of the sprocket. When two electric hoists are used in tandem, since all parameters of different electric hoists cannot be exactly the same, this will lead to inconsistent operating steps of different electric hoists, resulting in deviations in lifting and lowering, and the deviations can be accumulated. After a certain period of time, there may be a large deviation at the lower end of the electric hoist. Therefore, it is recommended to select two electric hoists of the same model and connect them to a synchronous controller, or directly use a single double-hook electric hoist. The two hooks of the double-hook electric hoist are directly hooked on both ends of the support pad 230.

[0025] Among them, the moving frame 210 includes two vertical rods 211, a cross bar 212 fixedly connected between the tops of the former two, and rollers 213 installed at the inner bottom of the vertical rods 211; the cross beam 240 is fixedly connected between the cross bars 212 of the two moving frames 210; the guide rail 100 is a long U-shaped groove, and the rollers 213 are slidably connected inside the guide rail 100. The two ends of the guide rail 100 are preferably fixed to the side of the bed edge by bolts 120.

[0026] Among them, two fixing straps 231 are provided on the support pad 230, which are used to fix the shoulders or legs of the patient. The fixing straps 231 can be selected from common elastic bands to have certain adjustable performance.

[0027] During the process of lifting and lowering the patient, the motor of the electric hoist vibrates during operation, and the patient will also sway to a certain extent. As a result, the rollers 213 of the moving frame 210 may roll accordingly. To improve the stability of the entire device during use, the lying patient transfer device further includes a fixing mechanism 300. The fixing mechanism 300 includes a pressing plate 310, a lower wing plate 320, an upper wing plate 330, fastening screws 340 and a pressing strip 350; raised ribs 110 are provided at the top and bottom of the guide rail 100; the pressing plate 310 covers the outer sides of the bottoms of the two vertical rods 211; one end edge of the lower wing plate 320 is fixedly connected to the lower edge of the pressing plate 310, and the other end is located below the guide rail 100 and is provided with a first flange 321 that hooks the rib 110; one end edge of the upper wing plate 330 is fixedly connected to the upper edge of the pressing plate 310, and the other end passes between the two vertical rods 211 and is provided with a second flange 331 that hooks the rib 110; the fastening screw 340 is threadedly connected to the pressing plate 310, and its end penetrates into the guide rail 100 and can press against the bottom surface of the guide rail 100 after being tightened; the pressing strip 350 is fixed to the top of the upper wing plate 330, and its end is close to the inner side of the vertical rod 211. A rubber pad 360 is fixedly connected to the end of the fastening screw 340 to ensure the tightening effect after tightening. The fastening screw 340 can be selected as a butterfly screw to facilitate the rotation of the fastening screw 340.

[0028] The fixing mechanism 300 is used after moving the moving frame 210 to the required position to prevent it from shifting during the subsequent patient lifting and lowering process and to ensure the stability of the entire device. During use, by tightening the fastening screw 340, its end abuts against the bottom surface of the guide rail 100, and the pressing strip 350 presses against the vertical rod 211, so as to squeeze the bottom of the entire moving frame 210 from two directions, which can achieve a firm fastening effect and prevent the moving frame 210 from shifting and large-amplitude swaying. When it is necessary to move the moving frame 210, only need to loosen the fastening screw 340.

[0029] The above has introduced the lying patient transfer device provided by the present invention in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the technical solution and its core idea of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
