Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation equipment, and in particular to an anti-spasmodic wrist joint vibration rehabilitation hand rest. Background Art

[0002] Motor neuron damage in patients with hemiplegia, stroke or cerebral palsy, as well as some patients with burns, usually manifests as typical upper limb flexor spasms and lower limb extensor spasms. Upper limb flexor spasms often manifest as finger and wrist flexion spasms. Finger flexion spasms will cause the patient's fingers to become deformed due to long-term contracture, and eventually form an irreversible "hook hand", leaving lifelong disability. Finger and wrist flexor spasms seriously affect the recovery of upper limb motor function. Therefore, patients with finger and wrist flexion spasms need to take reasonable measures for rehabilitation treatment in a timely manner to help patients recover their finger and wrist motor function and prevent complications and secondary damage in the later stage. Summary of the invention

[0003] In order to solve the above problems, the present invention provides an anti-spasm wrist joint vibration rehabilitation hand support.

[0004] The specific contents are as follows: An anti-spasmodic wrist joint vibration rehabilitation hand support, comprising a forearm support plate and a vibration hand support connected by a seismic isolation spring, and is characterized by:

[0005] The forearm support plate is a long strip with a C-shaped cross section. A plurality of isolation springs extending along the length direction are fixed on the inner end surface of the forearm support plate. The free end of each isolation spring is correspondingly fixed to the handle of the vibration hand support. The end surface of the handle of the vibration hand support matches the end surface of the inner end of the forearm support plate in shape and has a corresponding position.

[0006] The forearm support plate is provided with at least two arm straps, one end of each arm strap is fixed to the edge of the forearm support plate, and a fixing hole corresponding to the position of the fixed end of the arm strap is provided on the edge of the other side of the forearm support plate, and the fixing hole matches the arm strap;

[0007] A vibrator penetrating the thickness of the vibration hand rest is fixed on the vibration hand rest, and five finger straps are arranged on the upper surface of the vibration hand rest. The distribution of the finger straps corresponds to the positions of the fingers of a naturally opened hand.

[0008] Preferably, a battery mounting box is provided on the lower surface of the outer end of the forearm support plate, in which a battery is installed and connected to the vibrator through a wire.

[0009] Preferably, the vibrating hand rest is provided with a palm strap, one end of which is fixed to the edge of the vibrating hand rest, the palm strap spans the vibrating hand rest and the free end of the palm strap passes through a fixing ring provided on the other side of the vibrating hand rest.

[0010] Preferably, the arm straps, finger straps and palm straps are all nylon straps with Velcro.

[0011] Beneficial technical effects of the present invention:

[0012] The present invention discloses an anti-spasm wrist joint vibration rehabilitation hand support, comprising a forearm support plate and a vibration hand support connected by a vibration isolation spring, the forearm support plate is a long strip plate with a C-shaped cross section, at least two arm straps are arranged on the forearm support plate, a plurality of vibration isolation springs extending along the length direction of the forearm support plate are fixed on the inner end surface of the forearm support plate, the free end of each vibration isolation spring is correspondingly fixed to the handle of the vibration hand support, a vibrator penetrating the thickness of the vibration hand support is fixed on the vibration hand support, five finger straps are arranged on the upper surface of the vibration hand support, the distribution of the finger straps corresponds to the positions of each finger of a naturally opened hand, and a palm strap is also arranged on the vibration hand support; the patient's forearm and fingers are respectively fixed on the forearm support plate and the vibration hand support. The hand is put on a support and tied up with a strap. The flexed and spasmodic fingers are forced to open through the finger straps to avoid contracture of the finger flexor muscles. The vibration of the vibrator is then used to force the wrist joint to move, helping the patient to recover the movement function of the fingers and wrist. Since the vibrating hand rest and the forearm support plate are connected by a seismic isolation spring, the vibration generated by the vibrating hand rest will not be transmitted to the forearm support plate, thereby avoiding simultaneous vibration of the palm and forearm, and the forearm support plate can play a role in relatively fixing the forearm, so that the vibration generated by the vibrator is applied to the palm as much as possible, prompting the palm to produce a relatively large vibration amplitude as much as possible, thereby passively moving the wrist joint, preventing complications and secondary damage in the later stage, and helping the patient to recover quickly.

[0017] Example 1, see Figure 1-3 , an anti-spasmodic wrist joint vibration rehabilitation hand support, comprising a forearm support plate and a vibration hand support connected by a seismic isolation spring;

[0018] The forearm support plate is a long strip with a C-shaped cross section. A plurality of isolation springs extending along the length direction are fixed on the inner end surface of the forearm support plate. The free end of each isolation spring is correspondingly fixed to the handle of the vibration hand support. The end surface of the handle of the vibration hand support matches the end surface of the inner end of the forearm support plate in shape and has a corresponding position.

[0019] The forearm support plate is provided with at least two arm straps, one end of each arm strap is fixed to the edge of the forearm support plate, and a fixing hole corresponding to the position of the fixed end of the arm strap is provided on the edge of the other side of the forearm support plate, and the fixing hole matches the arm strap;

[0020] A vibrator penetrating the thickness of the vibration hand rest is fixed on the vibration hand rest, and five finger straps are arranged on the upper surface of the vibration hand rest. The distribution of the finger straps corresponds to the positions of the fingers of a naturally opened hand.

[0021] A battery installation box is arranged on the lower surface of the outer end of the forearm support plate. A battery is installed in the battery installation box and is connected to the vibrator through a wire. The vibrator can be powered by the battery, and the vibrator is convenient to carry.

[0022] The vibrating hand rest is provided with a palm strap, one end of which is fixed on the edge of the vibrating hand rest, the palm strap spans the vibrating hand rest and the free end of the palm strap passes through a fixing ring on the other side of the vibrating hand rest, and the palm strap is used to fix the palm to the vibrating hand rest.

[0023] The arm straps, finger straps and palm straps are all nylon straps with Velcro, which can be easily fixed and released.

[0024] The use process and principle of the present invention:

[0025] The patient's forearm and fingers are fixed on the forearm support plate and the vibrating hand support respectively, and the forearm and fingers are tied tightly with corresponding straps. The flexed and spasmodic fingers are forced to open with the finger straps to avoid contracture of the finger flexor muscles. The wrist joints are then forced to move through the vibration of the vibrator to help the patient recover the movement function of his fingers and wrists. Since the vibrating hand support plate is connected to the forearm support plate by a seismic isolation spring, the vibration generated on the vibrating hand support plate will not be transmitted to the forearm support plate, thereby avoiding simultaneous vibration of the palm and forearm. The forearm support plate can play a role in relatively fixing the forearm, so that the vibration generated by the vibrator is applied to the palm as much as possible, prompting the palm to produce a relatively large vibration amplitude as much as possible, thereby passively moving the wrist joint, preventing complications and secondary damage in the later stage, and helping the patient to recover quickly.
