Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to an anti-extubation alarm split restraint device with a soothing function. Background Art

[0002] In clinical scenarios such as psychiatry, ICU, and geriatric care, restraints, as important medical devices for protecting patient safety, face the dual challenges of technical optimization and humanistic care in their rational application. Existing restraints generally have structural defects: traditional fabric restraints rely on the experience of nursing staff to adjust the tightness, and there is a risk of peripheral circulation disorders caused by delayed pressure perception; while rigid fixation devices can ensure restraint strength, they are prone to joint stress injuries due to the lack of ergonomic design. Studies have shown that 32% of restraint-related adverse events are caused by skin damage caused by insufficient breathability of the device, while 18% of self-release cases are directly related to the single restraint site design.

[0003] With the development of medical Internet of Things technology, traditional restraints have shortcomings in intelligent auxiliary functions such as real-time pressure monitoring, early warning, and soothing. In view of this, we propose an anti-extubation alarm split restraint device with soothing function. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-extubation alarm split restraint device with a soothing function to solve the problems pointed out in the background technology.

[0005] The technical solution of the present invention provides a split-type restraint device with an anti-extubation alarm and a soothing function, comprising:

[0006] A restraint glove, the wrist-wrapped design comprising a half-finger silicone skin-contacting layer and a hard plastic layer, the hard plastic layer being provided on the outer layer; a soothing ball being fixedly provided on the palm of the restraint glove; and a soothing module being fixedly provided on the back of the palm of the restraint glove; the soothing module comprising a protective box, within which are disposed a plurality of micro linear resonant motors arranged in a matrix;

[0007] The restraint gloves are sequentially provided with a half-finger silicone skin-fitting layer and a hard plastic layer from the inside out. The half-finger silicone skin-fitting layer is provided close to the skin and uses medical-grade skin-friendly silicone material to improve wearing comfort and protect the skin. The hard plastic layer provides support. The overall half-finger design facilitates observation of blood circulation at the fingertips. The wrist end adopts a wrist-wrapped design and can be set in a variety of models to adapt to different personnel. The soothing ball is made of soft material, and can be a round silicone ball with moderate elastic deformation. It is integrated and installed in the palm of the hand. On the back of the palm, multiple micro linear resonant motors are installed in a matrix in the protective box. The (LRA) array can imitate human slapping movements and provide soothing movements.

[0008] A concave base, the concave base being fixed to the bed, and the concave base being equipped with a tension direction conversion mechanism, a tension detection mechanism, a microcomputer, and a movable locking mechanism;

[0009] The tension detection mechanism includes an electronic tension detector and a slide. The electronic tension detector is fixed on a concave base. The detection end of the electronic tension detector is in transmission connection with the slide. The slide is slidably mounted on the concave base. The protective box is connected to a connecting belt. The connecting belt passes through the tension direction conversion mechanism and is in transmission connection with the slide.

[0010] When the tension detected by the electronic tension detector reaches a preset threshold, the microcomputer locks the slide through a movable locking mechanism.

[0011] By adopting the above technical solution, the concave base is fixed on the bed frame by a bolt structure, providing a stable support base for the tension direction conversion mechanism, the tension detection mechanism, the microcomputer and the movable locking mechanism. The palm of the mentally ill patient is restrained by the restraining glove. Since the connecting belt passes through the tension direction conversion mechanism and transmits the connecting slide, when the palm of the mentally ill patient has the action of extubating the tube, the palm of the mentally ill patient moves to pull the connecting belt. Under the guidance of the tension direction conversion mechanism, no matter how many angles the palm moves, the end of the connecting belt and the slide move in a straight line. The electronic tensile tester can be moved to move linearly, pulling the slide along the concave base, and driving the detection end of the electronic tensile tester to move through the slide, so as to monitor the tension of the palm of the mental patient by using the electronic tensile tester, so as to determine and monitor the agitation of the mental patient. When the tension reaches the preset threshold, the microcomputer triggers the alarm and locks the slide through the active locking mechanism, limiting the range of movement of the palm, warning of "unplanned extubation" behavior, reducing the medical risks caused by catheter detachment, and using multiple miniature linear resonant motors to imitate human slapping movements to provide soothing actions.

[0015] By adopting the above technical solution, the restraint gloves can be provided in various models to adapt to the palms of different patients. A tightening mechanism is set at the wrist position. The strap is inserted into the elliptical shell so that the ratchet is inside the rectangular groove. By rotating the ratchet, the strap with the ratchet bar moves along the elliptical shell, which can realize the tightening of the wrist position of the restraint glove. When disassembly is required, the T-shaped shaft is manually pulled to elastically deform the reset spring and disengage the ratchet from the engagement with the ratchet bar, so that the strap can be pulled out of the circular shell to expand the wrist position port of the restraint glove.

[0016] Optionally, a connection end is provided on the outside of the protective box, and the connection belt is located at the patient end and is detachably connected to the connection end. The connection belt is a hollow structure with a signal line inserted inside. The signal line is used to electrically connect the micro linear resonant motor and the microcomputer.
