Description

Protective tool for elbow joint pain

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to a protection apparatus for elbow joint is painful.

Background

The major pathogenesis of Lateral Epicondylitis (LE) is strain or injury of the extensor carpi radialis muscle due to insufficient muscle strength of the supinator muscle, which is either a grasping action or an antagonistic muscle, and degenerative changes, of which the change of the extensor carpi radialis is the most common. Causing tendinosis, degeneration and tearing of the muscle origin, which is painful. (Garg et al.2010; Nirschl and Ashman 2003; Kroslav and Murrel 2007)

It is characterized by pain on the lateral humerus, extension of the wrist joint, increased pain and reduced grip strength on the posterohumeral lateral epicondyle (Garg et al 2010; Struijs et al 2005) and sensitivity of the proximal muscle group of the radius (Trudel et al 2004). Although lateral epicondylitis is also known as "tennis elbow", LE (Garg et al.2010) present in tennis players is less than 5-10%, actions that occur in various types of excessively repetitive tasks, including repetition of grasping actions, or the process of pronation to supination, are more likely to cause the appearance of LE (Garg et al.2010; krollav and Murrel 2007; Anderson and Rutt 1992) including surgeons, musicians, housewives (Anderson and Rutt 1992), construction, installation occupations, manufacturing and feeding processes (Trudel et al.2004). The probability of 40-50% of tennis players appearing describes the annual incidence of 1-3% of the general population (G Garg et al 2010; Bauer and Murray 1999; Meyer et al 2002). The right-hand holding of the mouse for a long time by the army net and the lateral movement of the mouse are designed to be groups which are easy to induce LE by wrist joint holding, flexion and extension and forearm rotation

The current situation and the problem are as follows:

domestic and domestic

Currently, the navy warriors belong to the LE high-hair population, however, the treatment means for LE are various, including rest, ice compress, physical therapy, nonsteroidal anti-inflammatory drugs (NSAIDs), local injection, exercise therapy, functional elbow joint support, platelet rich plasma injection, botulinum toxin injection, surgery, etc., while the optimal treatment method remains a pending problem [ TANG H Y, YU T, WEI W, et al.2019 ].

2. Relevant documents 1554 are searched by the Chinese knowledge network by taking the external humeral epicondyle as a key word, wherein more than 1140 documents are traditional Chinese medicine treatment methods, and then shock wave treatment, local injection treatment, operation treatment and platelet injection treatment are carried out. Therefore, the LE treatment mode in China is mainly the traditional treatment mode and the anti-inflammation of the medicine. And inconsistent with the expectation of recovery of the patient. And these approaches are only useful as a treatment for post LE onset pain without altering the relatively altered humeral-radial relationship and the unbalanced extensor carpi and supinator forces. The recurrence rate of the previous methods is high, and the research on braces is rarely reported.

3. While the treatment method of LE by MWM is a simple sticking treatment method, the sticking treatment method has the obvious defects of long time consumption, easy allergy of sticking cloth, easy falling of sticking cloth, high economic cost and time cost and incapability of popularizing the whole army.

4. Elbow protectors on the market mainly protect elbow joints under the action of heat preservation and pressurization, and elbow joint position adjustment of LE patients is not targeted.

Second, foreign countries

1. The University of Kentucky (2009) proves that MWM has obvious therapeutic effect on LE through clinical observation tests, and the therapeutic significance can be derived from three aspects: 1. during MWM treatment, there was a 58% improvement in painless grip strength; 2. the results of study two: during MWM, 92% of subjects were able to perform previously painful movements, with a 46% improvement in pain-free grip strength immediately after treatment and a 10% improvement in stress-pain threshold immediately after treatment; MWM produces hypoalgesia (no painful grip and improvement in pressure-pain threshold) and physiological sympathetic excitation (opportunity for heart rate, blood pressure, cutaneous tone and vasomotor function); and Abbott (2001), MWM is considered a manual treatment strategy that uses forces that affect biomechanical joint alignment, thereby facilitating the required motion.

2. However, the foreign deficiency is similar to the domestic deficiency, and the alignment of the elbow joint is maintained by the patch for a long time, and the patch is not easily popularized to the whole army due to high cost, high operation difficulty, long time consumption, easy falling and allergy.

as shown in fig. 1 and 2, the present embodiment provides a protective tool for elbow joint pain, which includes a wrist guard-like brace 1 to be worn on an elbow joint of a patient; the protective equipment 1 is internally provided with a spiral channel along the spiral direction of the right hand, a pressure air bag 2 is arranged in the spiral channel and used for supporting the supinator after the pressure air bag 2 is inflated, and the relationship between the asymmetric supinator and the extensor carpi is stabilized by pressurizing in the spiral direction of the right hand, so that the real stability among the elbow joint muscle groups is achieved; the inner part of the protective tool 1 is also provided with an arc-shaped air bag 3 which is positioned at one end of the protective tool and corresponds to the outer side of the radius of a human body, so that the arc-shaped air bag 3 can provide sliding pressure to the outer side of the radius after being inflated, and the elbow joint can be aligned by pressurizing the arc-shaped air bag 3 on the outer side of the radius; the pressure air bag 2 penetrates through the arc-shaped air bag 3 and is communicated with the arc-shaped air bag 3. So that it can be filled with gas simultaneously when inflated. The pressure air bag 2 arranged in the protective clothing 1 forms a spiral routing direction, the spiral direction is a right-hand spiral direction, the overstraining of extensor muscles is possibly related to the weakness of supinator muscles, and the supinator muscles serving as extensor antagonistic muscles can resist the overstrained wrist extensor muscles, so the routing in the direction of the supinator muscles can support the supinator muscles to maintain the internal stability of the elbow joint; secondly, the tense extensor carpi may produce a great stress on the humeral lateral epicondyle attachment resulting in a supination of the humerus relative to the radioulnar joint, and the stress from the pressure balloon 2 in the right hand spiral direction will change this relationship.

The wrist-protecting type protective clothing is designed to be conveniently worn at the elbow joint of a patient, the spiral channel arranged along the spiral direction of the right hand in the protective clothing 1 can enable the pressure air bag 2 in the protective clothing to also form a spiral structure arranged along the spiral direction of the right hand, so that pressurization in the spiral direction of the right hand is formed and is supported by the supinator, the relationship between the asymmetrical supinator and the extensor carpi is stabilized, and the real stability among elbow joint muscle groups is achieved; then, the arc-shaped air bag 3 pressurizes the air bag on the outer side of the radius to provide sliding force on the outer side of the radius, so that the elbow joint is aligned on the biomechanics level of the elbow joint in daily behaviors, the elbow joint is maintained to be stable through external support to reduce the occurrence of injury risks, and the movement of the alignment of the inner track of the joint can achieve the effect of treating LE and even preventing LE.

As a specific implementation manner, it should be further noted that the width of the arc-shaped air bag 3 after being deployed is one third of the diameter of the protector 1, and the length of the arc-shaped air bag 3 is not more than one half of the length of the protector 1, so as to ensure that sufficient pressurization can be given to the radius part of the human body. It should be noted that the arc-shaped airbag 3 has an arc-shaped configuration, and is just suitable for being worn on an arm.

One end of protective equipment 1 is provided with aerifys ball 4, aerifys ball 4 and passes through pipeline intercommunication pressure gasbag 2, conveniently aerifys and the gassing for pressure gasbag 2 and arc gasbag 3 through aerifing ball 4, makes it reach the operation requirement, also can adjust the pressure that pressure gasbag 2 and arc gasbag 3 produced through aerifing ball 4 simultaneously, conveniently pressurizes and the decompression to reach and carry out the outside of radius at any time and pass and produce uncomfortable urgent adjustment in wearing. Of course, it should be noted that the inflation of the inflatable ball 4 is only a preferred way of the present embodiment, and there are many specific ways of inflating the inflatable ball 4 in the prior art, and the inflatable ball 4 in the present embodiment is not limited as only one.

The main technology of the protective clothing for generating the treatment effect is derived from the mobility with mobility mwm technology. The development of lateral epicondylitis is closely related to the imbalance of the strength of extensor carpi and supination muscles, and when the extensor carpi is overstrained, it will cause a great tension to the humerus in the total tendon attached to the lateral epicondylium of the humerus, resulting in lateral displacement of the humerus relative to the radius and relative pronation of the humerus to the ulnar joint. The occurrence of the displacement will more easily cause the muscles to be pinched in the brachioradial joint with changed relationship during the stretching of the wrist joint, and the initial length of the extensor carpi is shortened due to the change of the relationship of the brachioradial joint, so that the exertion degree during the contraction of the muscles is higher. And the stress of the right hand screw direction of the protective protector can change the elbow joint displacement of the pathological state, the radius position retraction and the muscle clamping damage risk caused by joint change reduction.
