Description
Technical Field
The application relates to the field of medical equipment, in particular to a radial nerve injury hand function exerciser.
Background
The radial nerve (radial nerve) is formed by the emission of the anterior branch into the posterior tract of the 5 th to 8 th cervical nerves and the 1 st thoracic nerve. The major dyskinesia after injury is paralysis of extensor muscles of forearms, which is characterized by "prolapse of wrist" when the forearms are lifted, failure of dorsal extension of metacarpophalangeal joints of fingers, failure of extension of thumbs, supination disorder of forearms, and hypoesthesia or disappearance of skin on the radial side of arms.
The upper level of the flexor elbow has weakness in the metacarpophalangeal joints and the wrist joints, and the long-time flexor tendon can not draw the vertical finger and the wrist in time for functional exercise, so that the wrist joints and the hand joints are adhered, and even if the nerve function recovery or function reconstruction operation is carried out in the later period, the treatment effect is not good because the wrist joints and the interphalangeal joints are adhered.
For the exercise of hand functions, the traditional brace cannot better meet the requirement of human engineering in terms of flexibility, comfort and scientificity, and particularly does not attach importance to the exercise of the wrist stretching function, so that the wrist joint is limited by the brace when stretching to a neutral position and cannot stretch back in a limited way; traditional brace is comparatively stiff when taking exercise, and the exercise action that can accomplish is limited and the comfort is relatively poor, and this has the people of obstacle to hand function, and not only the degree of difficulty is great but also be difficult to persist, and the process is comparatively painful.
Secondly, because patient group age, sick factor such as degree of lightness differ, lead to the exercise dynamics requirement to hand function exerciser different, along with the degree of rehabilitation training, time are different moreover, also changing the demand to the exercise dynamics, want to keep best exercise demand, need the continuous adjustment of patient, and most of patients are unwilling to go frequent adjustment because of complex operation, lead to the rehabilitation to take exercise the effect poor, the cycle length.
Disclosure of Invention
The utility model aims to provide a radial nerve injury hand function exerciser, which can better accord with human engineering through flexible design, thereby greatly enhancing the flexibility and comfort of exercise; in addition, the patient can instantly finish adjustment by holding the strength, which is very convenient and reduces the fussy operation and pain in the rehabilitation process.
A radial nerve injury hand function exerciser comprises an elbow sleeve, a top supporting rod, a side supporting rod, a lever, a finger sleeve and a palm support; the method is characterized in that:
the top of the elbow arm sleeve is provided with a top support rod, the side part of the elbow arm sleeve is provided with a side support rod, and the side support rods and the top support rod are distributed at an angle of 90 degrees;
a lever is hinged on the top supporting rod, the rear end of the lever is connected with a palm support through a pull rope, and the front end of the lever is connected with a finger sleeve through the pull rope;
the side supporting rod is connected with the finger stall through a pull rope.
Preferably, the elbow arm cover is plastics, and the material that low temperature thermoplasticity board, rubber etc. had certain intensity wantonly is made, and the even louvre that is equipped with is sheathe in the elbow arm, and the elbow arm can be fixed it on the forearm through magic subsides tie, and the elbow arm cover is open structure along the axial.
Furthermore, a cushion layer is arranged on the contact surface of the elbow arm sleeve and the forearm, and the cushion layer is made of any soft cloth such as gauze, a sponge layer and cotton cloth.
Preferably, at least one set of clamping grooves is arranged on the top support rod.
Preferably, the lever is provided with an arching point, and the arching point is clamped in the clamping groove to prevent the support rod from sliding in the clamping groove.
Preferably, the rear end of the lever is transversely provided with a cross beam, and two ends of the cross beam are respectively connected with two ends of the palm support through pull ropes.
Preferably, the pull cord is both a stretch cord and a non-stretch cord.
Further, the elastic rope comprises a latex tube, a tension spring, an elastic belt and the like.
Preferably, the finger stall is provided with five, the front end of the lever is connected with four, and the side supporting rod is connected with one.
The beneficial effects of the utility model reside in following:
the finger bending strength and the wrist stretching strength can be freely converted, and the finger stretching strength and the wrist bending strength can be freely converted. The conversion amount is freely and instantly regulated and controlled by the patient according to the self needs of the patient. The strength problem of bending and extending the finger wrist generally does not need to adjust the brace on the functional exerciser, and the use is very convenient.
The support accords with ergonomics, appears along with the wrist stretching action when the fingers are bent in a normal natural relaxing state of a human body, naturally strengthens the wrist stretching force amount when the fingers are bent for a patient with the upper level injury of the radial nerve elbow, and promotes and strengthens the completion of the wrist stretching action; secondly, the natural relaxed state of the normal human body appears along with the action of extending the fingers when bending the wrist, and the brace naturally strengthens the force of extending the fingers for the patient with the horizontal injury on the radial nerve elbow, promotes and strengthens the completion of the action of extending the fingers.
This application travelling comfort is strong, and this brace does not restrict the wrist and bends and stretch the interdynamic, can promote wrist joint function exercise on the contrary, more effectively promotes wrist joint to resume, uses through clinical patient, and the recovery process is comfortable, and the cycle is short, increases and wears travelling comfort and practicality.
The back stretching force of the brace is respectively shared by the fingers and the wrists (the traditional brace only applies the total back stretching force to the fingers and then transmits partial force to the wrists by the fingers to enable the wrists to complete the back stretching action, which causes the finger joints to stretch too strongly to cause the fingers to be uncomfortable), thereby increasing the flexibility, the controllability and the comfort of the movements of the wrists of the fingers of a patient.
The nerve innervates each joint activity, the functional training counter-stimulation of a certain joint corresponds to the nerve recovery, the brace refines the flexion and extension activities of the fingers and the wrist respectively, and can be extended simultaneously or flexed singly, and the recovery of the innervated nerve is promoted due to the free conversion of the force.
The total bending and stretching strength of the brace is regulated and controlled by the lever fulcrum on the top supporting rod, the patient can freely adjust the height of the fulcrum to realize the total bending and stretching strength of the wrist part, the adjustability is fast and practical, the fulcrum is dragged, and complicated links of transmission knob type adjustment are reduced.
