This invention relates to the field of medical and nursing device technology, and in particular to a restraint-type distance-sensing anti-extubation alarm glove and its method of use. The glove includes a restraint glove with a fixing strap on one side of its surface. A magnet is fixedly connected to the top of the fixing strap, and a magnet is disposed within the inner cavity of the magnet. This invention combines physical restraint with intelligent early warning, catheter positioning, and catheter angle adjustment. Through a specially designed enclosed space on the right side of the restraint glove's inner cavity, the range of motion of the patient's ring and little fingers is physically restricted, effectively preventing the patient from pulling the tube by clenching their fist. Simultaneously, a distance monitoring system is constructed using positioning chips one, two, and three. When hand movements pose a risk, multiple alerts are provided through different colored lights, alarm sounds, and vibrations, offering comprehensive warnings to the patient and medical staff from auditory, visual, and tactile dimensions, allowing for timely measures to prevent extubation.

The present disclosure describes a method and apparatus for performing multiple measurements on a boxing punch (or other similar push action in motion). These measurements may provide force, acceleration, four types of response times, 3D angle, velocity, accuracy / precision, rate of force development, straight punch (pricking or cross punch) efficiency, SPR metrics (force, precision, response times), and / or other information. The apparatus to make related measurements uses one or more force sensors and one or more motion sensors that are embedded in boxing gloves and / or objects that are punched (pushed) (e.g., sandbags or mittens). If a tablet screen is used to make a fist area and display an opponent, a set of position sensors may be used to measure the accuracy of the fist (push). These novel methods and devices may be used for boxing (or push) testing, evaluation and training activities, as well as for fitness and sports games.

The device designed to develop hand-eye coordination in boxing is a research-based tool consisting of several parts. It enhances offensive boxing skills for students and athletes of all ages. Considered an important tool for learning and training, the device includes a movable iron base with adjustable height to accommodate different boxer heights. Attached to this base are iron rings, each 25 cm in diameter, which allow for the insertion of a fist. The boxer with the boxing glove and the number of these rings (7) rings distributed for the straight punch, the side punch and the upward punch. The researchers wrapped these seven rings with a rubber material to ensure the principle of safety when punching. These rings were connected to a light beam that was fixed to the rings and electrical connections were made to them. An electrical card prepared for this purpose was programmed for these rings so that these rings would flash randomly. An electrical source was prepared for the device and supplied with a battery in case of power outage to take advantage of all the available time for training.

This invention discloses a grip strength ball for rehabilitation of hemodialysis patients, belonging to the field of medical device technology. It aims to solve the technical problem that existing grip strength balls, which only allow for a single gripping motion, easily increase fatigue in the patient's palm and make it difficult to exercise the fingers. The invention includes an upper hemisphere and a lower hemisphere, connected by a fist-rebounding component. A finger pressing component is arranged on the top of the upper hemisphere, and a telescopic adjustment component is arranged inside the lower hemisphere. The upper and lower hemispheres are adjusted and controlled by the telescopic adjustment component, allowing for both a close proximity state and a separated state. This invention has the advantages of allowing patients to exercise with a hollow fist, sensing the force of the fist grip by applying pressure to the grip strength ball to assess the degree of rehabilitation, and simultaneously facilitating finger flexibility exercises, thus meeting the needs of two types of rehabilitation exercises.
