When any of the locking rings is pulled, the double-axis rotating gear 207 will be driven to rotate, and the gear shaft 204 on the other side will also slide, thereby realizing synchronous opening and closing. The hoop kit 2 is connected to the fixed guard arm 1 through the clamping shaft 205. The first locking ring 201 and the second locking ring 202 are connected, and one end of each of the first locking ring 201 and the second locking ring 202 is provided with a magnetic block 206, and the first locking ring 201 and the second locking ring 202 are connected by the magnetic block 206, and a filling rubber sleeve 203 is provided on the outer side of the magnetic block 206, and the filling rubber sleeve 203 is connected to the magnetic block 206 through a slot, and a plurality of adjusters 4 are provided at the bottom of the elbow support 101, and the adjusters 4 are connected to the elbow support 101 through the mounting slot 1011, and the hoop kit 2 can fix the arm guard 1 without hand support when the patient moves, so as to facilitate the transfer of the patient;

[0031] After the arm is placed inside the fixed arm guard 1, the synchronous opening and closing operation of the two sets of locking rings can be realized by pulling any one of the first locking ring 201 and the second locking ring 202. After the two sets of locking rings are closed and contacted, they are fixed by the magnetic block 206 on the end surface.

[0033] Each adjuster 4 corresponds to a set of metal tendons 104. When adjusting, pressing the finger on the rotating groove 402 can contact the damping ring 4052, and the reel 405 can be rotated through the damping ring 4052. When the traction belt 401 is rotated, the stretching and releasing operation of the traction rubber band 1041 can be realized. When locking after adjustment, the locking block 4081 on the inner side of the lock button 408 is rotated into the core shaft 4051 to lock the reel 405. When the lock button 408 is locked, the reel 405 cannot rotate at a large angle, and even if a slight angle of rotation occurs, it will be reset under the torsion of the torsion spring, so that the slight movement adjustment of the palm can be facilitated in the locked state, and the fatigue of the hand in a long-term posture can be relieved.

[0034] See also Figure 7-8The arc-shaped end surface of the metal tendon 104 is provided with a limiting sleeve 1044, and the limiting sleeve 1044 is fitted with the metal tendon 104, wherein one end of the limiting sleeve 1044 is provided with a traction rubber band 1041, and the other end of the limiting sleeve 1044 is provided with a retaining rubber band 1042, one end of the traction rubber band 1041 is sutured and connected with the traction belt 401, and the retaining rubber band 1042 is connected with the fixed arm guard 1 through a card slot, and the traction rubber band 1041 is affected by the rotation traction of the adjuster 4. When tightened, the metal tendon 1041 is tightened under the action of the traction rubber band 1041. The arc segment of the bone tendon 104 will bend upwards, and when released, the retaining rubber band 1042 will help the arc segment of the metal bone tendon 104 to be reset. The traction rubber band 1041 and the retaining rubber band 1042 are connected to the arc end of the metal bone tendon 104 through the jacket 1043. The traction rubber band 1041 and the retaining rubber band 1042 are connected to the jacket 1043 through a sliding groove. The jacket 1043 and the limiting sleeve 1044 can both play a limiting and guiding role on the rubber band structure to avoid the rubber band from being misplaced during stretching.

[0035] The metal tendon 104 with an arc-shaped structure is embedded in the interior of the fixed arm guard 1, wherein the arc-shaped end is located inside the palm rest 103. This area will correspond to the patient's hand during use. The arc-shaped end of the metal tendon 104 can be adaptively adjusted according to the patient's needle embedding position. When the patient is receiving an infusion on the back of his hand, the front end of the metal tendon 104 remains bent downward. At this time, the patient's palm can naturally fall on the palm rest 103, and the palm is supported by the palm rest 103 to avoid hand fatigue. When the patient is receiving an infusion in his arm, the front end of the metal tendon 104 can be adjusted by the adjuster 4 at the bottom of the elbow rest 101 to bend it outward, and the back of the patient's hand contacts the palm rest 103 area. In both support methods, the corresponding metal tendon 104 can be stretched and adjusted by the adjuster 4 to achieve the most comfortable angle for the patient.

[0036] Working principle: the area below the elbow of the patient's arm can be placed in the fixed arm guard 1, which can play a good wrapping and supporting role to avoid hypothermia of the hand in a long-term infusion environment. The arc-shaped end of the metal tendon 104 can be adaptively adjusted according to the patient's needle embedding position. When the patient's back of the hand is infused, the front end of the metal tendon 104 keeps bending downward. At this time, the patient's palm can naturally fall on the palm rest 103, and the palm is supported by the palm rest 103 to avoid hand fatigue. When the patient is infused in the arm, the front end of the metal tendon 104 can be adjusted by the regulator 4 at the bottom of the elbow rest 101 to bend it outward, and the back of the patient's hand is in contact with the palm rest 103 area. In both support methods, the corresponding metal tendon 104 can be adjusted by the regulator 4 The tendons 104 are stretched and adjusted to achieve the most comfortable angle for the patient. Each adjuster 4 corresponds to a group of metal tendons 104. When adjusting, pressing the finger on the rotating groove 402 can contact the damping ring 4052, and the winding wheel 405 can be rotated through the damping ring 4052. The traction belt 401 can realize the stretching and release operation of the traction rubber band 1041 when rotating. When locking after adjustment, the locking block 4081 on the inner side of the locking button 408 is turned into the core shaft 4051 to realize the locking of the winding wheel 405. When the locking button 408 is locked, the winding wheel 405 cannot rotate at a large angle, and even if it rotates at a slight angle, it will be reset under the torsion of the torsion spring. In this way, the slight movement adjustment of the palm can be convenient in the locked state, and the fatigue of the hand in a long-term posture can be relieved.
