Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
The hand support for radial artery puncture is designed according to the connection relation of the human bodies, and comprises a back plate 1, wherein the back plate 1 is placed on the back of a patient and used for fixing the whole hand support for radial artery puncture; one side of the back plate 1 is movably connected with an upper arm supporting plate 2, and the upper arm supporting plate 2 is used for correspondingly placing an upper arm; swing joint has underarm layer board 3 on the upper arm layer board 2, and underarm layer board 3 is used for corresponding the bearing underarm.
As shown in fig. 1 and 2, the lower arm supporting plate 3, the upper arm supporting plate 2 and the back plate 1 are in strip-shaped structures, and are respectively adapted to the lower arm, the upper arm and the trunk of the human body.
And each structural plate can relatively movably rotate to imitate the motion trail of human arms, so that the arms can be placed on the hand supports more fittingly.
The upper arm pallet 2 includes an upper arm rest area 7 and a lower connecting arm area 8, and the upper arm rest area 7 is connected to the lower connecting arm area 8.
Wherein the upper arm of upper arm layer board 2 is placed regional 7 and is connected through swivel pin 4 with backplate 1, and the shoulder joint function is realized in the simulation of this swivel pin 4, and the axis of swivel pin 4 sets up perpendicularly for upper arm layer board 2 uses the vertical line as the axis of rotation, round the vertical line, rotates on the horizontal plane.
As shown in fig. 1, the lower arm supporting plate 3 is connected with the lower arm connecting region 8 of the upper arm supporting plate 2 through an elbow rotor 5, and the elbow rotor 5 simulates the function of an elbow joint; the lower arm pallet 3 is rotated on the horizontal plane around the vertical line with the vertical line as a rotation axis; the elbow rotor 5 is arranged on the front outer side of the lower arm supporting plate 3, so that the elbow rotor can be attached to the change of outward movement when the elbow of a human body rotates.
The elbow rotor 5 comprises a first rotating part 9 and a second rotating part 10, the first rotating part 9 and the second rotating part 10 are sleeved together and can coaxially rotate, and rotating shafts of the first rotating part and the second rotating part are vertically arranged; the first rotating part 9 is positioned above the second rotating part 10, a hole or a shaft is formed in the bottom of the first rotating part 9, the top of the second rotating part 10 is correspondingly provided with the shaft or the hole, the hole or the shaft of the first rotating part 9 is matched with the shaft or the hole of the second rotating part 10, the bottom of the first rotating part 9 is in contact with the top of the second rotating part 10, and the first rotating part 9 and the second rotating part can realize relative rotation; meanwhile, the bottom surface of the first rotating member 9 is an inclined surface or a spiral surface, the top surface of the corresponding second rotating member 10 is an inclined surface or a spiral surface, and the inclination or the spiral direction of the bottom surface of the first rotating member 9 is the same as that of the top surface of the second rotating member, wherein when the upper arm supporting plate 2 is positioned on the left side of the back plate 1, the rotating direction of the spiral surfaces of the first rotating member 9 and the second rotating member 10 is left-handed; when the upper arm supporting plate 2 is positioned at the right side of the back plate 1, the rotating directions of the spiral surfaces of the first rotating piece 9 and the second rotating piece 10 are right-handed.
