Specific embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among the embodiment described range.
A kind of medical precise micro killer injecting pump as shown in Figure 1, including
One body 1 has the support base 9 of a pair of of support syringe on body 1, is provided on support base 9 and is affixed with syringe 200
The U-shaped groove of conjunction is located between two support bases 9 on body 1 and is additionally provided with inverted U-shaped limit base 8, the inner wall of limit base 8 with
Syringe 200 fits, while having a pair of of fixing seat 81 on body 1, and an appearance limit base 8 is all had in fixing seat 81
The groove of bottom end insertion, and fixed by pin shaft 82 after limit base 8 is embedded in fixing seat 81, connection specifically: in limit base 8
Bottom end and fixing seat 81 on all have and hold the through-hole that passes through of pin shaft 82, pass through after the groove that limit base 8 is embedded in fixing seat 81
Pin shaft 82 sequentially pass through through-hole in fixing seat 81,8 bottom end of limit base through-hole after, realize fixing seat 81 and limit base 81 it
Between it is relatively fixed, pin shaft 82 is fixed by connecting band 83 and 8 phase of limit base, using the cooperation of connecting band 83, also for keeping away
Exempt from pin shaft 82 arbitrarily to abandon.By adding limit base 8 between two support bases 9, thus to the front-end position of syringe 200 into
Row limit, avoids during use, 200 leading portion of syringe is upturned and influences going on smoothly for injecting liquid drug；And
For limit base 8 using the fit system of fixing seat 81 and pin shaft 82, so that limit base 8 is easy to disassemble, to cooperate syringe 200
Pick-and-place.
The moving assembly of one piston handle 202 for clamping syringe 200, moving assembly include movable block 2 and installation
Clamp system on movable block 2 and for clamping piston handle 202, movable block 2 are driven by the executing agency 3 being mounted on body 1
It moves and drives piston handle 202 mobile.Executing agency 3 is ball wire rod mechanism, and movable block 2 is mounted on the nut of ball wire rod mechanism
On.
Clamp system includes the first movable plate 4, the second movable plate 5, shaft, the first unilateral bearing, the second unilateral bearing, the
One movable plate 4 and the second movable plate 5 are respectively corresponded in the two sides of 200 piston handle 202 of syringe, when the first movable plate 4 and second
After movable plate 5 clamps 200 piston handle 202 of syringe, movable block 2 can drive piston handle 202 mobile.
Shaft 601 is spindle rotationally arranged on movable block 2, specifically, the both ends of shaft 601 have flange 201, movable block
2 both ends are equipped with the fulcrum bearing that bearing shaft 601 rotates, and have the annular for accommodating the flange 201 in shaft 601 in fulcrum bearing
Slot, the flange 201 in shaft 601 cannot be moved axially under the limitation of annular groove and can only be circumferentially rotated.
The equal interference of inner ring of first unilateral bearing 602 and the second unilateral bearing 603 covers in shaft 601 or by key peace
In shaft 601, i.e. the inner ring of the first unilateral bearing 602 and the second unilateral bearing 603 rotates together with shaft 601.First
The outer ring rotating of unilateral bearing 602 and the second unilateral bearing 603 is contrary, the first unilateral bearing 602 and the second unilateral bearing
External screw thread having the same rotation direction on 603 outer ring, the first movable plate 4 and the second movable plate 5 respectively with the first unilateral bearing 602
It is threadedly engaged with the outer ring of the second unilateral bearing 603.It should be noted that unilateral bearing is a kind of prior art, unilateral bearing
It is a kind of bearing that can be freely rotated, and lock in the other directions in one direction, herein no longer to its internal junction
Structure is described further.
First assume that the outer ring of the first unilateral bearing 602 when shaft 601 rotates clockwise can instantaneously rotate clockwise, second is single
To the static difference in the outer ring of bearing 603, then the outer ring of first unilateral bearing 602 is then when the rotation of the hour hands counterclockwise of shaft 601
Static, the outer ring of the second unilateral bearing 603 is static instantaneously to be rotated counterclockwise.When shaft 601 rotates clockwise, the first one-way shaft
Holding 602 outer ring can drive the first trap to move right, and turn after the piston handle 202 of the first movable plate 4 and syringe 200 contacts
Axis 601 rotates counterclockwise, at this point, the first movable plate 4 is static, the second movable plate 5 is moved to the left, when the second trap plate and syringe
After 200 piston handle 202 contacts, the first movable plate 4 and the second movable plate 5 clamp piston handle 202, and then movable block 2 is mobile,
First movable plate 4 and the second movable plate 5 can drive the piston of syringe 200 mobile to carry out injecting liquid drug.After the completion of injection,
The first and second movable plate can be rotated manually increases the distance between first and second movable plate.
It is also equipped with displacement sensor on movable block 2, while being also equipped on body 1 and being connected with displacement sensor
Alarm.By the limit sensors added on movable block 2, the moving position of piston handle 202 can be detected, and passed through
The cooperation of alarm reminds medical care people to sound an alarm in the case where piston handle 202 occurs blocking etc. and can not be successfully promotion
Member is handled, and the safety of product is improved.
Body 1 is equipped with position-limit mechanism 7 corresponding with 2 limit position of movable block, and position-limit mechanism 7 includes slide 701, traveller
702 and spring 703, slide 701 be fixed on body 1, traveller 702 is slidably disposed on slide 701,703 pairs of cunnings of spring
Column 702 applies elastic force；For movable block 2 during being moved to limit position, movable block 2 can push traveller 702 to overcome spring 703
Resistance it is mobile and under the effect of traveller 702 movement extremely limit, movable block 2 is limited by traveller 702, prevents its movement
Excessively syringe 200 is damaged
Position-limit mechanism 7 further includes being mounted on body 1 close to switch 704, close to switch 704 when movable block 2 is moved to limit position
When, it can sense traveller 702 close to switch 704 and send a signal to controller, controller receives the signal close to switch 704
After to can control executing agency 3 out of service.
Angle steel 705 on body 1 is provided with the through-hole for passing through close to switch 704 on angle steel 705, approaches the shell of switch 704
Upper two bung flanges 706 for having external screw thread and being threadedly engaged with external screw thread, two bung flanges 706 are located at the two sides of angle steel 705,
Two bung flanges 706 can will be fixed after contacting with angle steel 705 close to switch 704.
Working principle: after the syringe interior suction of syringe 200 enters medical fluid, movable block 2 and the first movable plate 4 and the second movable plate
5 initial distance meets: the distance between the first movable plate 4 and the second movable plate 5 are greater than the thickness of 200 piston handle 202 of syringe
Degree, the barrel flange 201 of syringe 200 is caught in the groove 101 of body 1, and limit base 8 is then embedded in the recessed of fixing seat 81
In slot, at this point, the outer wall of the inner wall fitting syringe 200 of limit base 8, is then fixed limit base 8 using pin shaft 82, syringe
200 piston handle 202 is between the first movable plate 4 and the second movable plate 5, and then clamp system 6 drives 4 He of the first movable plate
Second movable plate 5 is moved together to clamp piston handle 202, then by triggering and controlling by the operation button on body 1,
Then, it recycles executing agency 3 to drive the movement of movable block 2, to drive piston handle 202 mobile, carries out injecting liquid drug.
It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, above-described embodiment and explanation
