Description

Self-heating correction ring capable of adjusting flexion contracture of finger joint

Technical Field

The utility model relates to a medical treatment rehabilitation apparatus technical field, concretely relates to finger joint function correction ring.

Background

Flexion contracture of finger joints is commonly seen in various types of nerve paralysis patients after central nervous system injury, and is mainly characterized in that the flexion of the affected limb is difficult to extend due to the over-high tension of the affected side muscle. The fingers of the light person are bent and are not extended easily, and the fingers of the heavy person are held strongly and cannot be extended, so that the recovery of the finger joint function and the daily life capability of the patient are seriously influenced.

At present, the finger orthoses are mostly applied clinically to relieve the flexion contracture of finger joints and improve the functions of the finger joints. Most finger orthotics on the market are usually composed of a palm surface splint, a finger collar and a hand back collar (ran in the vernal wind. Clinical application of forearm, wrist, palm and finger orthotics: eleventh national cerebrovascular disease rehabilitation conference of the chinese medical society [ C ]. Fujian, china, fujian, 2008). The palm guard plate is used as a main frame of the finger orthosis and is made of a high-temperature thermoplastic sheet material. The thumb ferrule, the forefinger ferrule, the middle finger ferrule, the ring finger ferrule and the small finger ferrule are respectively connected to a palm splint plate of the main frame through elastic bands; the wrist-arm ferrule is connected on the wrist of the palm splint through an elastic band, so that the aim of statically fixing and inhibiting the flexion contracture of the finger joint is fulfilled. However, such finger orthoses have certain limitations in clinical applications. Firstly, the finger orthosis is poor in aesthetic property, portability and comfort, fingers are fixed on a hard plastic plate through finger ferrules, the skin of the fingers can be damaged when the finger orthosis is worn for a long time, the finger joints and the wrist joints can be forcibly fixed, so that the daily life activities of patients are inconvenient, and the compliance of the patients wearing the orthosis is obviously reduced. Secondly, the utility and convenience of such orthoses are not high. Most finger orthotics on the market are only of three types, namely children, young people and adults, the diameter of a finger ring cannot be finely adjusted, and overtightness can influence the blood circulation of the fingers of a patient and can cause inflammation of soft tissues around joints; too loose can not achieve the purpose of inhibiting the flexion spasm of the finger joints. Finally, such static fixation of fingers and wrists orthoses is less accurate and effective. Although most patients with central nervous system injury will have a certain degree of flexion contracture of the finger joint, the degree of flexion contracture of the finger joint of each patient is different, and not all the finger wrists exhibit significant flexion contracture. For some patients with better recovery degree of the finger joint function, each finger is not required to be statically fixed to inhibit the joint contracture, and the finger joint function recovery of the patients can be influenced by wearing the orthosis for a long time.

As explained in the background of the prior art, most of the existing aids in the market use the finger pressing plates, once the five fingers are worn, the fingers with relatively good functions can not move flexibly, the finger pressing plates are too large in size, and the carrying performance and the aesthetic performance are both deficient. The acupressure plates on the current market generally have no warming function and can only be simply fixed, and the warming function can better relieve the contracture of the joint of a patient, so that the appearance is ensured, and the contracture of the joint of the patient is relieved to the greatest extent. Conventional thermotherapy is now mainly based on electronic heating, but its loss is relatively severe and safety is poor.

The utility model discloses the patient can be according to the diameter of finger joint flexion contracture severity self-regulating ring, and the finger joint that will contracture stiff and straight tends to stably under the state of passive draft to make soft tissue obtain furthest's release and extension around the finger joint of contracture, prevent pain and the dysfunction that arouse by long-term joint contracture. And simultaneously, the utility model discloses utilize the phase transition principle of physics chemistry, produce the momentum through breaking off with the fingers and thumb the interior little iron sheet of ring, make the supersaturated sodium acetate solution solidification of original liquid form, utilize the exothermic principle of liquid solidification to reach the purpose of warm effect, its self-heating function can improve the not smooth adverse reaction of blood circulation around the contracture joint that is brought by long-term static fixed orthopedic ware, alleviates the disuse atrophy of soft tissue around the joint, promotes finger joint function recovery. And after the supersaturated sodium acetate solution is solidified, the supersaturated sodium acetate solution can be re-liquefied by boiling water, so that the supersaturated sodium acetate solution can be repeatedly used, and the economic burden of a patient is reduced.

Compared with the prior art, the utility model discloses the advantage has following advantage: (1) the production is convenient, and no complex technical requirements exist.
