Description

Technical Field

[0001] This invention relates to the field of nursing equipment technology, specifically to a device for lifting the buttocks of critically ill patients in the nursing department. Background Technology

[0002] During the rehabilitation process, some patients who cannot walk normally in their lower limbs need to defecate in bed. Usually, the caregiver needs to place the bedpan under the patient's buttocks, and there needs to be a drain in the bed for defecation. When changing the bedpan, the patient's buttocks need to be lifted up to make it easier for the caregiver to change the bedpan. When changing the patient's clothes, the patient's buttocks also need to be lifted up to make it easier to change clothes.

[0003] The current method generally involves manually lifting the patient's buttocks, but this requires at least two people. It is not only physically demanding but also very inconvenient to operate, especially when there is only one caregiver. Improper operation may cause secondary injury to the patient. Using equipment to lift the patient's buttocks can easily cause the patient to slide to one side or roll over, requiring a caregiver to support them, which is a waste of manpower. Summary of the Invention

[0004] The purpose of this invention is to provide a hip-lifting device for critically ill patients in nursing departments, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hip-lifting device for critically ill patients in nursing departments, comprising a bed frame, wherein the bed frame has a placement groove inside, and two sets of positioning mattresses hinged together by connecting pieces are placed inside the placement groove, and a movable plate is placed between the two sets of positioning mattresses. A transmission component for driving the pressure block is installed inside the movable plate, and the bottom of the movable plate is hinged to a lifting component through a connecting column. The lifting component is used to adjust the height of the movable plate, and four sets of symmetrically arranged moving components are also installed at the bottom of the bed frame.

[0006] Furthermore, the transmission assembly includes a screw and a dual-axis motor. The dual-axis motor is fixed inside the mounting slot, which is located inside the top of the movable plate. Both output ends of the dual-axis motor are connected to the screw.

[0007] Furthermore, both sets of screws are threadedly connected to connecting sliders on the outside, and each set of connecting sliders is connected to a pressure block at its top.

[0008] Furthermore, the lifting assembly includes a hinge rod, a positioning rotating rod, and a servo motor. A mounting plate is fixed to the bottom of the connecting column, and a vertical block is provided at the bottom of the mounting plate. One end of the hinge rod is hinged to one side of the vertical block, and the other end of the hinge rod is hinged to one end of the positioning rotating rod. The other end of the positioning rotating rod is connected to the output end of the servo motor.

[0009] Furthermore, the servo motor is mounted on one side of a fixing block, which is fixed to the bottom of the bed frame.

[0010] Furthermore, the bottom of the bed frame is symmetrically provided with several sets of ventilation slots.

[0011] Furthermore, the movable component includes a support column and casters, the support column being fixed to the bottom of the bed frame, and the casters being rotatably limited by the support column.

[0012] Furthermore, the bottom sides of the movable plate are connected to limiting plates, which extend through the limiting grooves, which are located inside the bottom ends of the two sets of positioning mattresses.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention starts a dual-axis motor to drive the screw to rotate, so that the two sets of screws first drive the two sets of pressure blocks to clamp the patient's hips inward. Then, the servo motor is started to drive the positioning rod to rotate around the output shaft, so that the hinge rod lifts the mounting plate, thereby raising the movable plate to lift the patient's buttocks. Under the clamping of the pressure blocks, the patient can remain stable when the buttocks are lifted, preventing side slippage or rollover, which facilitates nursing care.

[0015] 2. The limiting plate set in this invention drives the two sets of limiting plates to move upward when the movable plate is raised, so that the limiting plate moves the near end of the two sets of positioning mattresses to lift up, avoiding injury to the patient caused by only the movable plate being raised, and improving the patient's comfort. The casters enable the device to move to facilitate transportation. Attached Figure Description

[0021] 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.

[0022] Please refer to Figure 1-4 As shown, this invention is a hip-lifting device for critically ill patients in the nursing department, including a bed frame 1. The bed frame 1 has a placement groove 17 inside, and two sets of positioning mattresses 4, which are hinged together by connecting pieces, are placed inside the placement groove 17 to support the patient. A movable plate 5 is also placed between the two sets of positioning mattresses 4 to raise the patient's hip position. A transmission component for driving pressure blocks 8 is installed inside the movable plate 5. The transmission component is used to drive the two sets of pressure blocks to move, so that the two sets of pressure blocks 8 clamp the hip bones on both sides of the patient's hip, preventing side slippage and side roll when the hip is lifted. The bottom of the movable plate 5 is hinged to a lifting component through a connecting column 10. The lifting component is used to adjust the height of the movable plate 5, thereby lifting the patient's hip. Four sets of symmetrically arranged moving components are also installed at the bottom of the bed frame 1, so that the device can be easily moved.

[0023] Please refer to Figure 3 and Figure 4 As shown, the transmission assembly includes a screw 6 and a dual-axis motor 7. The dual-axis motor 7 can rotate asynchronously so that the two sets of pressure blocks 8 are displaced in opposite directions. The dual-axis motor 7 is fixed inside the mounting groove 20, which is located inside the top of the movable plate 5. Both output ends of the dual-axis motor 7 are connected to the screw 6, which can drive the two sets of screws to rotate simultaneously. The external parts of the two sets of screws 6 are threaded with connecting sliders 21. The top of each of the two sets of connecting sliders 21 is connected to a set of pressure blocks 8. When the screw 6 rotates, it drives the pressure blocks 8 to move through the threaded connecting sliders 21.

[0024] Please refer to Figure 1 and Figure 2As shown, the lifting assembly includes a hinge rod 13, a positioning rotating rod 14, and a servo motor 15. A mounting plate 11 is fixed to the bottom of the connecting column 10. One end of the hinge rod 13 is hinged to one side of a block 12 at the bottom of the mounting plate 11. The other end of the hinge rod 13 is hinged to one end of the positioning rotating rod 14. The other end of the positioning rotating rod 14 is connected to the output end of the servo motor 15. Starting the servo motor 15 drives the positioning rotating rod 14 to rotate. The positioning rotating rod 14 rotates around the output end of the servo motor 15, enabling the hinge rod 13, which is hinged to it, to rotate around the positioning rotating rod 14. The height of the movable plate 5 is adjusted by rotating the movable plate. The servo motor 15 is installed on one side of the fixed block 16, which is fixed to the bottom of the bed frame 1. Several sets of ventilation slots 18 are symmetrically provided at the bottom of the bed frame 1 to increase the breathability of the bed frame. Limiting plates 9 are connected to the bottom sides of the movable plate 5. The limiting plates 9 pass through the limiting slots 19. The limiting plates allow the positioning mattresses 4 on both sides to be slightly raised when the movable plate is raised, so as to avoid only the movable plate 5 being raised and to increase the patient's comfort. The limiting slots 19 are opened inside the bottom ends of the two sets of positioning mattresses 4.

[0025] Please refer to Figure 1 and Figure 2 As shown, the moving component includes a support column 2 and casters 3. The support column 2 is fixed to the bottom of the bed frame 1, and the casters 3 are connected to the support column 2 for rotational limitation. The casters 3 enable the device to move freely and facilitate transfer.

[0026] Working principle: This invention is a hip lifting device for critically ill patients in the nursing department. First, when it is necessary to lift the patient's hip, the dual-axis motor 7 is started to drive the screw 6 to rotate. The two sets of screws 6 first drive the two sets of pressure blocks 8 to clamp the patient's hips inward. Then, the servo motor 15 is started to drive the positioning rotating rod 14 to rotate around the output shaft, so that the hinge rod 13 lifts the mounting plate 11, thereby raising the movable plate 5 to lift the patient's hip. Under the clamping of the pressure blocks 8, the patient's hip can remain stable when lifted, preventing side slippage or rollover, which facilitates nursing care.

[0027] Furthermore, when the movable plate is raised, it drives the two sets of limiting plates 9 to move upward, causing the limiting plates 9 to tilt and lift the near ends of the two sets of positioning mattresses 4, thus avoiding injury to the patient caused by only the movable plate 5 being raised, and improving the patient's comfort. The casters 3 enable the device to move, making it convenient for transportation.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
