Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a restraint device for nursing care. Background Technology

[0002] In psychiatric nursing, appropriate restraint of patients' limbs is an important safety measure. Currently, restraint is usually achieved by binding the two ends of a restraint strap to both sides of the bed. However, this method has several problems: the restraint strap is inconvenient to install and remove, and needs to be cleaned and stored when not in use; the length of the restraint strap is inconvenient to adjust, usually through the limiting holes on the strap, which is cumbersome and cannot be precisely adjusted; the fixed position of the restraint strap is affected by the bed structure, making it impossible to adjust it to better suit different patients.

[0003] Therefore, how to solve the above-mentioned technical problems has become the subject of this utility model. Utility Model Content

[0004] The purpose of this invention is to provide a nursing restraint device that is easy to adjust precisely, thereby making it more applicable.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a restraint device for nursing care is provided, including a number of mounting boxes arranged horizontally under the hospital bed, a winding roller is rotatably connected to the inner side of the mounting box, a restraint belt is wound on the winding roller, and the free end of the restraint belt passes through a groove on one side of the mounting box and is fixedly connected to a fixing plate.

[0006] The mounting box is equipped with a drive component that drives the winding roller to rotate and a manual fine-tuning component that cooperates with the constraint belt.

[0007] The hospital bed includes a headboard and a footboard, with a bed board frame horizontally arranged between the headboards, and a mattress placed on the bed board frame;

[0008] The bed frame has parallel connecting rods on both sides below it, and the top of the mounting box is also provided with these rods.

[0009] The two sides are provided with upper sliding grooves that slide with the bottom of the two sides of the bed board frame, and the bottom of the mounting box is provided with lower sliding grooves that slide with the connecting rod.

[0010] The mounting box has two pairs of ear plates symmetrically arranged on the upper and lower sides at both ends. The ear plates on the upper and lower sides are respectively provided with fixing holes. Several through adjustment holes are vertically opened between the connecting rod and the bed board frame. Fixing pins are inserted between the adjustment holes and their corresponding fixing holes.

[0011] The adjustment holes are evenly distributed and located between the fixing holes on the left and right sides of the same end of the mounting box.

[0012] The distance is an integer multiple of the distance between two adjacent adjustment holes.

[0013] The driving component includes a dual-axis motor located on the side of the winding roller away from the groove. The output ends on both sides of the dual-axis motor are coaxially sleeved with a first transmission disc. The two sides of the rotating shaft of the winding roller are coaxially sleeved with a second transmission disc. A transmission belt is sleeved between each first transmission disc and the second transmission disc located on the same side.

[0014] Inside the mounting box, a pair of limiting rollers are symmetrically rotatably connected on the upper and lower sides near the through slot.

[0015] The constraint band passes between the two limiting rollers, which are made of elastic rubber, and the distance between the two limiting rollers is less than the thickness of the constraint band.

[0016] The outer wall of the mounting box is equipped with control buttons for controlling the forward and reverse rotation of the dual-axis motor.

[0017] The manual fine-tuning component includes an adjusting roller disposed between the winding roller and the limiting roller, and adjusting rods are coaxially fixedly connected to both sides of the adjusting roller, with the adjusting rods rotatably connected to the inside of the mounting box;

[0018] The outer wall of the adjusting roller has a transverse through-groove, and the constraint band extends from within the adjusting groove.

[0019] The adjustment rod on one side is coaxially sleeved with a worm gear, which meshes with a worm. The worm is rotatably connected to the inside of the mounting box, and the end of the worm near the through groove extends to the outside of the mounting box and is fixedly connected to a handle.

[0020] The fixing plate is rectangular, and a handle is provided on the outer wall of the fixing plate. Through holes are provided at the four corners of the fixing plate.

[0021] The mounting box has a rectangular groove on the side away from the through slot, and the four corners of the inner wall of the groove...

[0022] Each is provided with a fixedly connected insertion rod that mates with the insertion hole. The insertion rod has an external thread near its outer end and is threaded with a nut.

[0023] In practical use, this invention works as follows: First, determine the number and position of restraint straps based on the patient's body shape and condition. Secure the straps using a sliding mounting box and fixing pins. Then, start the dual-axis motor. The motor drives the winding roller via a transmission belt, releasing the restraint straps. The caregiver can quickly pull the restraint straps out through the handle, around the patient on the bed, to the other side. Align the insertion hole with the insertion rod, tighten the nuts to secure the fixing plate, and retract and fix the length of the restraint straps by reversing the dual-axis motor. This initially restrains the patient, at which point the restraint straps are relatively loose. Further manual adjustment is then made according to the actual situation. Rotating the handle drives the worm gear, which in turn drives the worm wheel, which in turn drives the adjusting roller. The adjusting roller retracts the outer restraint straps, allowing for slight adjustments to the tension of the restraint straps to achieve a good restraint effect while minimizing harm to the patient.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. The installation box of this utility model allows the restraint straps to be conveniently stored inside the box when not in use, making the storage and use process convenient.

[0026] 2. This utility model, through its structure of multiple mounting boxes that slide and can be positioned on the hospital bed, allows for quick adjustment of the positions of multiple restraint straps, making it more versatile.

[0027] 3. This utility model can quickly release and retract the restraint belt by setting a dual-axis motor. The restraint belt can be further fine-tuned by a manual fine-tuning component. The adjustment state is locked by the self-locking property of the worm gear and worm wheel. While ensuring convenient operation, it also meets the different usage requirements of different patients, achieving effective restraint while minimizing harm to the patient.
