Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a fall protection warning device. Background Art

[0002] During surgery, in addition to the conventional body positions, special body positions are often required. These include inclined positions such as left high and right low, or left low and right high, head high and foot low, or head low and foot high. In such special body positions, not only does the risk of the patient falling off the operating table during the operation increase, but also the risk of pressure injury caused by excessive pressure on the inclined part increases. Because under general anesthesia or when the patient is sedated and sleeping, the patient cannot judge their position on the long operating table, and after the surgical drapes are laid, the surgeon, anesthesiologist, and nurse cannot correctly judge the position of the patient and whether there are risks of falling and pressure injury. The currently used anti-fall straps have a single structure, cannot completely protect patients in all special body positions, and cannot evaluate during the operation whether there are risks such as falling and pressure injury. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a fall protection warning device, which can fix specific parts of the patient in special body positions, not only solve the possible fall risk, but also play a role of reminder and warning.

[0004] Its technical solution is as follows: A fall protection warning device, characterized in that it includes a support pad, a chute is provided on the outer peripheral surface of the support pad, a slidable strap mechanism is provided in the chute, the strap mechanism includes sliding fixing blocks on both sides and elastic straps connecting the two ends of the sliding fixing blocks, the longitudinal section of the elastic strap is a flat ellipse, and an alarm is fixed in the middle of the top of the elastic strap, stretching lines are provided at both ends of the alarm, and the ends of the stretching lines are fixed to the two ends of the elastic strap.

[0005] It is further characterized in that a silica gel layer is provided on the support pad; Fixing plates are respectively provided on the left and right sides of the support pad; A toothed bar is provided on one side in the chute, a retractable convex block that cooperates with the tooth groove of the toothed bar is provided on one side of the sliding fixing block, and a button for controlling the expansion and contraction of the retractable convex block is provided on the sliding fixing block; A telescopic control block is provided at the middle position of the elastic strap, and a pressing switch for controlling the telescopic amount of the elastic strap is provided on the telescopic control block.

[0006] After adopting the present invention, it is fixed on the operating bed. After the patient lies on it, the strap mechanism is used to fix the patient. The sliding fixing blocks at both ends can slide freely in the chute and are locked after being moved to the appropriate position, so as to fix specific parts of the patient, solve the possible falling risk, and the alarm on the elastic strap will give an alarm when the elastic strap is under tension, which can also play a role in reminding and warning.

DETAILED DESCRIPTION OF THE INVENTION

[0008] See Figures 1 to 7 As shown, an anti-fall protection and warning device includes a support pad 1. A silica gel layer 2 is provided on the support pad 1, which is soft and reliable to prevent pressure injuries to the compressed parts under the patient. The support pad 1 is an aluminum plate, which not only has high strength but also can be fluoroscoped during the operation.

[0009] A chute 3 is provided on the outer peripheral surface of the support pad 1. In this embodiment, a split is provided at the lower part of the support pad 1 corresponding to the legs of the human body. A slidable strap mechanism 4 is provided in the chute 3. The strap mechanism 4 includes sliding fixing blocks 4-1 on both sides and an elastic strap 4-2 connecting the sliding fixing blocks 4-1 at both ends. The longitudinal section of the elastic strap 4-2 is a flat ellipse, and an alarm 4-3 is fixed in the middle of the top of the elastic strap 4-2. Tensile lines 4-4 are provided at both ends of the alarm 4-3, and the ends of the tensile lines 4-4 are fixed to both ends of the elastic strap 4-2. In the normal state, the tensile lines 4-4 are wound inside and will not trigger an alarm. When the two tensile lines 4-4 are stressed and stretched outwards to a certain extent, the alarm is triggered. Specifically, a mesh belt 4-5 is provided inside the elastic strap 4-2. When stressed, it will contract towards the middle. The two tensile lines 4-4 are respectively connected to both sides of the elastic strap 4-2. In the normal state, the tensile lines of the alarm 4-3 are wound inside. When the elastic strap 4-2 is under tension and the mesh belt 4-5 deforms, the two tensile lines 4-4 are pulled to both sides and change from the wound state to the released state, triggering an alarm signal, and the alarm 4-3 gives an alarm to play a reminder role.

[0010] On the left and right sides of the support pad 1, fixing plates 5 are respectively arranged to fix the support pad 1, and it can be fixed to the hospital bed by screws in cooperation with locking parts. For example, Figure 2 As shown, the head of the screw sinks into the hole opened on the fixing plate 5 and will not affect the movement of the strap mechanism 4.

[0011] On one side inside the sliding groove 3, a toothed strip 6 is arranged. On one side of the sliding fixing block 4-1, a retractable convex block 4-6 that cooperates with the tooth groove of the toothed strip 6 is arranged. On the sliding fixing block 4-1, a button 4-7 for controlling the expansion and contraction of the retractable convex block 4-6 is arranged. When the button 4-7 is not pressed, the retractable convex block 4-6 extends out and is stuck in one of the tooth grooves of the toothed strip 6 to fix the sliding fixing block 4-1. When the button 4-7 is pressed, the retractable convex block 4-6 retracts. At this time, the sliding fixing block 4-1 can slide smoothly in the sliding groove 3, change its position. After moving to a suitable position, release the button 4-7, and the retractable convex block 4-6 extends out and gets stuck to achieve fixation. In the figure, 4-8 is the installation opening of the elastic strap.

[0012] At the middle position of the elastic strap 4-2, a telescopic control block 4-10 is arranged. On the telescopic control block 4-10, a pressing switch 4-9 for controlling the telescopic amount of the elastic strap is arranged. The elastic strap 4-2 passes through the telescopic control block 4-10 and is pressed. When the pressing switch 4-9 is pressed, the elastic strap 4-2 is no longer pressed tightly. At this time, the middle position of the elastic strap 4-2 can be pulled to make it expose from the middle of the telescopic control block 4-10. The lengths of the elastic straps on both sides can be adjusted according to the exposed amount. After adjustment in place, release the pressing switch 4-9 to press the elastic strap and complete the adjustment and fixation.

[0013] Multiple elastic straps 4-2 of different lengths can be selected according to needs, such as for chest fixation, shoulder fixation, waist fixation, and leg fixation. After the patient is fixed, if the patient tilts to one side and reaches a certain degree, the elastic strap 4-2 at that place is stressed and triggers the alarm of the alarm device.
