The cell body of adaptation.
Compared with prior art, beneficial effects of the present invention are as follows:
1st, the present invention passes through to arrange handle, shifting chute, the first threaded rod, the 3rd linear motion bearing, ball bearing and movable block,
It is used in conjunction with each other, has reached and be moved easily block in shifting chute movement and the movement of fixed column, and then facilitates to fixed deckle board
Move, strengthen the advantage that the different length to patient's arm can be fixed effectively;By arranging fixed column, first straight
Line motion bearings, rotor plate, the second threaded rod and mobile column, are used in conjunction with each other, and reached convenience carries out height to fixed deckle board
Degree is adjusted, and strengthens the advantage that can effectively fix to patient hand's differing heights;By arranging fixed deckle board, installing plate, note
Recall cotton block, accept block, second straight line motion bearings, the 3rd threaded rod, swivel plate and spring, be used in conjunction with each other, reach side
Just the movement of memory sponge block, strengthen can effectively fix and reduction of patient arm tensioned state to patient's arm difference rugosity
Advantage.
2nd, the present invention drives the rotation of the first threaded rod, the 3rd linear motion bearing to rotate on the first threaded rod by handle
It is mobile, movable block can be made to move in shifting chute, fixed column is moved at the top of base, and by swivel plate the 3rd screw thread is driven
Bar is rotated, and the movement of second straight line motion bearings suppresses to accepting block with installing plate, can be prevented effectively from spring unrestricted
Promotion accept block and installing plate movement occur memory sponge block patient's arm is clamped it is excessive, by the rotor plate inside fixed column
The second threaded rod is driven to rotate, first straight line motion bearings are moved on the second threaded rod so that first straight line motion bearings are pushed away
Dynamic mobile column is moved up, and can effectively strengthen that fixed deckle board moves up stablizes, so as to effective people blood drawing is produced it is tight
Open and fear, cause arm to tamper the state tightened with muscle so that doctor cannot be drawn blood, syringe needle wrong plug of drawing blood can be caused
Position, increased patient and fears sense to blood drawing, and then cannot complete blood drawing process, meanwhile, can also increase the product of unexpected injury
Raw, blood drawing auxiliary stand does not possess and is adjusted according to the state of patient's arm, the low problem of the suitability.
