[0013] Beneficial Effects

[0014] The present invention provides a device for preventing unplanned extubation, which has the following beneficial effects compared with the prior art:

[0015] 1. The medical staff will wrap the Velcro around the patient's wrist for a week and then stick them together to fix the Velcro on the patient's wrist. Then the medical staff will stick the contact sensor on the patient's finger. When the patient wants to extubate, when the contact sensor on the finger is 10CM away from the catheter, the sensor will emit light and sound to alert the medical staff, and simultaneously transmit the alarm signal to the receiver at the medical staff's duty station. At this time, the receiver will receive the alarm signal and display it on the central control screen, so that the medical staff can reach the patient in time; at the same time, the motor will be started, and the shaft fixedly connected to the motor output shaft will rotate synchronously, and drive the reel fixedly connected thereto to start rotating at a uniform speed. At this time, the reel will start to wind the drawstring fixedly connected thereto, and the drawstring will start to pull the Velcro fixedly connected thereto, thereby pulling the patient's wrist, keeping his hand away from the catheter, making it impossible to extubate, so as to avoid the medical staff being unable to quickly arrive to stop the patient's extubation behavior after the sensor alarms. The drawstring continues to pull the patient's hand to make it contact with the hand plate and fit it thereon. At this time, the motor continues to rotate, so that the drawstring continues to pull the patient's hand, causing the sliders symmetrically fixed on both sides of the hand plate to start sliding on the connecting rod and start compressing the springs fixedly connected thereto, so that the springs stop supporting the sliders and put them in a compressed state to facilitate pushing the hand plate to reset. At the same time, during the sliding of the hand plate, the gear rings on both sides thereof slide synchronously. Therefore, at this time, the gear rings start to rotate under the cooperation of the racks meshing therewith. At this time, the two gear rings rotate synchronously in opposite directions, and drive the arc plates fixedly connected thereto to rotate synchronously, so that the two arc plates synchronously rotate upward at their connection points with the hand plate, and begin to gradually dock. When the hand plate slides to contact the bottom of the frame, the two arc plates complete the docking, thereby cooperating with the baffle to close the hand plate, so as to restrain the patient's hands and prevent the patient from removing the Velcro from his wrists by himself, resulting in the inability to restrain the patient's hands.

[0016] 2. During use, the user places the base on both sides of the bed frame and starts to turn the dial. At this time, the left-hand screw fixedly connected to the axis of the dial starts to rotate, and drives the right-hand screw fixedly connected to it to rotate synchronously. At this time, the right-hand screw and the slide cylinder threaded on the left-hand screw start to move linearly along the connection between them and the base, so that the two splints fixedly connected thereon start to move towards each other, so that the two splints can cooperate with each other to clamp the bed frame, thereby fixing the base to the bed frame to prevent the base from being separated from the bed frame during the patient's struggle. At the same time, when the patient is about to extubate himself, when his finger is within 10CM of the catheter, the sensor on his finger controls the motor to start rotating, and the belt fixedly connected to the shaft rod is Wheel A rotates synchronously, and pulley B starts to rotate synchronously with pulley A under the cooperation of the belt connected to it for transmission, so that the lead screw fixedly connected to the axis of pulley B rotates at a uniform speed, and drives the slide plate threaded thereon, so that slide plate B starts to perform linear reciprocating motion along the connection between it and the limit rod. At this time, the connecting plate performs linear reciprocating motion synchronously under the action of the slide plate fixed to it and slide plate B, and drives the pressure cylinder rotatably connected thereon to slide synchronously, so that the draw belt is pulled by the pressure cylinder and guided so that it can be evenly wound on the reel, avoiding the draw belt being too long and causing it to be unevenly wound. At the same time, during the guiding process, since the two pressure cylinders are both rotating settings, they will not affect the winding of the draw belt on the reel.

[0029] For details, please refer to Figure 2 as well as Figure 5A concave hole is provided at the bottom of the hand plate 201, and a drawstring 206 runs through the concave hole. The drawstring 206 is fixedly connected to the Velcro 207. Arc plates 208 are symmetrically rotatably connected on both sides of the hand plate 201. Gear rings 209 are fixedly connected to the two arc plates 208 respectively. The gear rings 209 are meshed and connected to the rack 2001. The rack 2001 is fixedly connected to the frame 101, and the drawstring 206 is connected to the guide assembly 3.

[0030] In the embodiment of the present invention, the medical staff wraps the Velcro 207 around the patient's wrist for one week and then adheres them to each other, thereby fixing the Velcro 207 on the patient's wrist. Then the medical staff sticks the contact sensor on the patient's finger. When the patient wants to remove the tube, the contact sensor at the finger is close to the catheter at a distance of 10CM, and the sensor emits light and sound to alert the medical staff, and starts the motor 303 at the same time. At this time, the shaft 301 fixedly connected to the output shaft of the motor 303 rotates synchronously, and drives the reel 302 fixedly connected thereto to start rotating at a uniform speed. At this time, the reel 302 begins to wind the drawstring 206 fixedly connected thereto. At this time, the drawstring 206 begins to pull the Velcro 207 fixedly connected thereto, thereby pulling the patient's wrist, making his hand away from the catheter, making it impossible to remove the tube, so as to avoid the medical staff being unable to quickly arrive to stop the patient's extubation behavior after the sensor warns. When the drawstring 206 continues to pull the patient's hand to make it contact with the hand plate 201 and fit it, the motor 303 continues to rotate, so that the drawstring 2 06 Continue to pull the patient's hand, then the sliders 202 symmetrically fixedly connected on both sides of the hand plate 201 begin to slide on the connecting rod 203, and begin to compress the spring 204 fixedly connected thereto, so that the spring 204 stops supporting the slider 202 and puts it in a compressed state to facilitate pushing the hand plate 201 to reset. At the same time, during the sliding process of the hand plate 201, the gear rings 209 on both sides thereof slide synchronously. Therefore, at this time, the gear rings 209 begin to rotate with the cooperation of the rack 2001 meshing with it. At this time, the two gear rings 209 rotate synchronously in the opposite direction, and drive the arc plate 208 fixedly connected thereto to rotate synchronously, so that the two arc plates 208 synchronously rotate upward at their connection with the hand plate 201, and begin to gradually dock. When the hand plate 201 slides to contact the bottom of the frame 101, the two arc plates 208 complete the docking, thereby cooperating with the baffle 205 to close the hand plate 201, so as to restrain the patient's hands and prevent him from taking off the Velcro 207 from his wrist by himself, resulting in the inability to restrain the patient's hands.
