Description

Technical Field

[0001] The present invention relates to the technical field of restraint equipment, and in particular to a restraint device for a restless patient. Background Art

[0002] In the intensive care unit, awake agitated patients are a special and challenging group. Such patients may show agitated behavior due to various reasons (such as pain, anxiety, drug side effects, environmental stimulation, etc.), which not only affects the patient's comfort and treatment effect, but also may lead to adverse events such as unplanned extubation, falls, self-injury, etc. Although traditional restraint measures can prevent patients from engaging in dangerous behaviors to a certain extent, they may also bring problems such as discomfort, psychological pressure and damaged dignity to patients. In addition, the inventors found that when agitated patients are restrained by existing restraint devices, there is still room for activity in the patient's joints, and there is room for self-injury, injury to others, and extubation. Therefore, those skilled in the art hereby propose a technical solution for a restraint device for agitated patients. Summary of the invention

[0003] In view of the above background technology, when an agitated patient is restrained by an existing restraint device, there is still room for movement in the patient's joints, leaving room for self-injury, injury to others, and extubation. Therefore, a technical solution for a restraint device for an agitated patient is provided.

[0004] It includes a restraint bed structure, wherein four limb ankle and wrist restraints are arranged at the four corners of the top surface of the restraint bed structure, and four limb joint restraints are arranged at the four corners of the top surface of the restraint bed structure and located in front of the limb ankle and wrist restraints;

[0005] The restraint bed structure includes a steel bed frame, a steel bed board fixed on the upper surface of the steel bed frame, and a sponge mattress laid on the upper surface of the steel bed board, and four universal rollers are connected to the four corners of the bottom of the steel bed frame by screw locking;

[0006] The limb ankle and wrist restraint comprises a rear side plate located at the rear side and a front side plate located at the front side, and the side of the rear side plate and the front side plate close to each other is rotatably connected to two half-circle gears arranged in a left-right mirror symmetry, and an arc-shaped curved rod is fixed on the outer surface of each half-circle gear; a servo stepper motor is installed on the rear side surface of the rear side plate, and the output shaft of the servo stepper motor passes through the rear side plate and is connected to a driving gear, and a driven gear meshed with the driving gear is rotatably connected to the front side surface of the rear side plate, and the front end face of the driven gear is fixedly connected to the rear side surface of the half-circle gear on the left side; specifically, the two ankles and wrists of the agitated patient are respectively placed between the four groups of arc-shaped curved rods, and the driving gear is driven to rotate by the servo stepper motor, so that the driven gear is pulled to rotate by the driving gear, and the driven gear drives the half-circle gear on the left side to rotate, and because the two half-circle gears are meshed and bitten with each other, the arc-shaped curved rods can be gathered together or moved away from each other, and the ankles or wrists are clamped and restricted when the arc-shaped curved rods gather together. Based on the pressure sensor installed inside the arc-shaped bending rod, the servo stepper motor stops working and brakes when the inner side of the arc-shaped bending rod touches the ankle and wrist.

Specifically, before the patient's ankle and wrist are placed inside the limb ankle and wrist restraint, the elbow joint and knee joint are placed in the space between the two U-shaped brackets, and after tying and tightening the canvas binding straps, the limit pin is inserted from the pin hole into the spline shafts. Since the end of the limit pin is stuck in the meshing point between the spline shafts, the spline shafts cannot rotate with each other at this time, and the knee joint and elbow joint can be restricted by the U-shaped bracket and the canvas binding straps.

[0012] In the above-mentioned technical solution of the restraint device for a restless patient, preferably: the four limb, ankle and wrist restraints are all arranged in left-right mirror symmetry with the central axis of the steel bed board as the base point, the positions of the two limb, ankle and wrist restraints on the left side correspond to the positions of the ankle and wrist on the left side of the human body, and the positions of the two limb, ankle and wrist restraints on the right side correspond to the positions of the ankle and wrist on the right side of the human body.

[0013] In the above-mentioned technical solution of the restraint device for a restless patient, preferably: a layer of Velcro is adhered and fixed to the outer surface and the inner surface of the canvas binding belt, and the ends of the canvas binding belt pass through the inside of the U-shaped bracket respectively.

[0014] In the above-mentioned technical solution of a restraint device for a restless patient, preferably: the hinge points where the U-shaped brackets are close to each other are located at the node position of the knee joint or the elbow joint, and the side surfaces where the limit plates are close to each other are in contact with the left and right side surfaces of the spline shaft.

[0015] In the above technical solution of the restraint device for a restless patient, preferably: a circular hole for the nail pin to pass through is provided inside the limit plate and inside the spline shaft.

[0016] In the above technical solution of the restraint device for a restless patient, preferably: a limit pin is passed through the inner central position of the limit plate, and the end of the limit pin is inserted into the meshing point between the spline shafts.

[0034] Refer to the instruction manual Figure 5As shown: the limb joint limiter 3 includes two U-shaped brackets 31 hinged to each other, 3-5 canvas binding straps 32 are fixed on the outer ring surface of the U-shaped bracket 31, and a spline shaft 33 meshing with each other is fixed on one end of the U-shaped bracket 31 close to each other. A limit plate 34 is provided on the left and right sides of the spline shaft 33, and a nail pin passing through the spline shaft 33 is penetrated inside the limit plate 34.

[0035] Refer to the instruction manual Figure 3 As shown: two support groove steel plates 15 are welded to the left and right side surfaces of the steel bed board 12, and a support rod is welded to the top surface of the support groove steel plate 15, and the ends of the support rod are fixedly connected to the top surfaces of the rear side plate 21 and the front side plate 26. Two pieces 28 are welded between the rear side plate 21 and the front side plate 26, and there is a gap of 3.0cm-5.0cm between the rear side plate 21 and the front side plate 26 for the arc-shaped bending rod 27 to rotate in the gap.

After tying and tightening the canvas binding strap 32, the limit pin 35 is inserted from the pin hole 36 into the spline shafts 33. Since the end of the limit pin 35 is stuck in the meshing point between the spline shafts 33, the spline shafts 33 cannot rotate relative to each other at this time, and the knee joint and elbow joint can be restricted by the U-shaped bracket 31 and the canvas binding strap 32.
