Technical Field

[0001] This invention relates to the field of medical and nursing auxiliary equipment technology, specifically to an intelligent early warning and braking device for unplanned extubation of patients. Background Technology

[0002] Unplanned extubation, also known as accidental extubation, refers to extubation caused intentionally by the patient or by any accident. It usually includes the patient removing the catheter without the consent of medical staff, catheter slippage due to various reasons, the need to remove the catheter in advance due to catheter quality problems or catheter blockage, and catheter dislodgement due to improper operation by medical staff. Among these, the patient removing the catheter without the consent of medical staff is an important cause of accidental extubation. This situation often occurs in patients who are delirious or agitated in the early postoperative period. In current medical settings, a series of devices and equipment have emerged that can monitor and warn patients of unplanned extubation. However, intervention in the process of unplanned extubation still requires human intervention from medical staff. This undoubtedly increases the workload of medical staff, the probability of operational errors and injury to patients, and also adds burden to the operation of the entire medical system.

An electromagnet is embedded on the front side of the sleeve body 611. An elastic sleeve 613 is fixedly connected inside the sleeve body 611. The elastic sleeve 613 is located outside the radial electromagnetic plate 612 and inside the slip ring sleeve 62. A heating resistor 614 and a temperature sensor are embedded inside the elastic sleeve 613. Slip ring sleeve 62 is rotatably connected to the front side of sleeve body 611; Silent motor 63, the silent motor 63 is fixedly connected to the outer surface of the side panel 2; The flexible cable winch 64 is fixedly connected to the front of the silent motor 63, and the surface of the flexible cable winch 64 is fixedly connected to the top of the slip ring sleeve 62 by a flexible cable.

The early warning analysis component 8 includes a mounting slide rod 81 fixedly connected to the front side of the bed frame 1. A monitoring module 82 is fixedly connected to the top of the mounting slide rod 81 via a ball joint. The monitoring module 82 includes a camera 821 fixedly connected to the top of the mounting slide rod 81. An infrared module 822 is integrated on the front of the camera 821.

[0020] In use, the patient's forearm is passed through the restraint sleeve 61, and the elastic sleeve 613 is made to fit the patient's forearm skin. After the restraint sleeve 61 is placed in a stable position, the electromagnet inside the sleeve 611 is activated. The electromagnet inside the sleeve 611 pushes the radial electromagnetic plate 612 downward through electromagnetic force, thereby fixing the restraint sleeve 61 to the patient's forearm. The length of the fixing strap 5 is adjusted and inserted into the socket 4, so that the fixing strap 5 fixes the patient's upper torso. The silent motor 63 is controlled to rotate, so that the silent motor 63 drives the flexible cable winch 64 to rotate, unwinding the flexible cable. A certain length of flexible cable is reserved to facilitate the patient's normal daily activities. The camera 821 transmits patient images back to the controller 9 in real time. The controller 9 identifies the patient's intubation position and the position of the identification plate 83 based on the transmitted images. The position of the identification plate 83 and the posture data transmitted back by the sleeve 611 are used to help determine the position of the patient's arm. The infrared thermal image data transmitted back by the infrared module 822 is used to help locate the position of the identification plate 83 and the patient's posture. When the identification plate 83 is detected to be too close to the intubation position, the controller 9 controls the silent motor 63 to rotate. The silent motor 63 drives the flexible cable winch 64 to rotate and wind up the flexible cable. After winding is completed, the controller 9 controls the action electromagnet 722 to start. The action block 73 is driven to slide by adsorption, so that the action block 73 contacts the outer surface of the concentric head 71, thereby restraining the rotation of the flexible cable winch 64. At the same time, the electromagnet on the front of the sleeve 611 is energized to attract the slip ring sleeve 62, which increases the damping of the rotation of the slip ring sleeve 62 and prevents the patient from breaking free of restraint and pulling out the tube. At the same time, the buzzer 10 sounds an alarm under the control of the controller 9 to remind medical staff.
