Background technology
In the existing blood drawing checked operation, especially in arterial blood sampling observation operation, when puncture needle gets in the arteries; Because endarterial pressure is bigger, the blood back of a little can appear, after prompting is punctured successfully in the syringe needle; Bleeder needs in the one hand control direction and the degree of depth, to accomplish the blood drawing operation; Very inconvenience, and often smallly because of syringe needle in the process of blood drawing mobilely make it scratch blood vessel or in blood vessel, skid off, the blood drawing failure caused.
Summary of the invention
This utility model technical problem to be solved provides a kind of blood drawing rifle, and the one-handed performance in the time of can realizing drawing blood improves the accuracy of operation.
For solving the problems of the technologies described above; The technical scheme that this utility model adopted is: a kind of blood drawing rifle; Be slidingly fitted with sliding rack on the bearing; Be movably installed with slide clamp seat on the sliding rack, the sector gear that cooperates with sliding rack is installed in the bearing, trigger is hinged through push rod and sector gear middle part.
The axle of described sector gear is installed in the chute; Reversing bar also is installed in the bearing; The reversing bar upper end is equipped with the bridge joint gear, and the bridge joint gear is between sector gear and sliding rack, and reversing bar is also hinged through pull bar and sector gear near the position of the other end.
Described reversing bar becomes the shape of bending.
The other end of described reversing bar is provided with the switching-over button, and the switching-over button is positioned at arcuate groove.
Described sector gear below is provided with spring.
Described push rod is provided with spring.
The front end of described bearing also is provided with Fixing clamp-seat.
Also be provided with teeth groove on the described sliding rack, slide clamp seat cooperates with teeth groove through ratchet mechanism.
Described reversing bar is provided with the reversing bar axle, and the reversing bar axle is positioned at the position near chute.
A kind of blood drawing rifle that this utility model provides through syringe is fixed thereon, thereby can be implemented in the one-handed performance in the blood drawing operation, has improved the stability of operation and the accuracy of blood drawing.Through the reversing bar that is provided with, the one-handed performance when also can be implemented in injection.
This utility model adopts gear drive, reliable transmission, and when trigger was transferred to syringe, there was not circular runout in the piston of syringe, and when avoiding traditional rod member transmission, there is circular runout in the piston of syringe, thereby drives the dancing problem of syringe needle.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is described further.
Fig. 1 is the structural representation of this utility model.
Structural representation when Fig. 2 commutates for this utility model.
The specific embodiment
Embodiment 1:
This top of sentencing among Fig. 1 is the top; The direction at syringe 2 needle points place is the place ahead; A kind of blood drawing rifle is slidingly fitted with sliding rack 6 on the bearing 7, be movably installed with slide clamp seat 4 on the sliding rack 6; The sector gear 8 that cooperates with sliding rack 6 is installed in the bearing 7, and trigger 15 is hinged through push rod 14 and sector gear 8 middle parts.Piston rod with syringe 2 during use is fixed on the slide clamp seat 4, and front end sleeve is at bearing 7, behind the insertion arteries; Depress trigger 15, trigger 15 drives sector gear 8 through push rod 14 and is rotated counterclockwise, and drives the sliding rack 6 that meshes with sector gear 8 and moves backward; The piston rod that slide clamp seat 4 on it drives syringe 2 moves backward, realizes the one-handed performance of blood drawing, owing to adopt the pinion and rack transmission; When piston rod moves backward, there is not circular runout.Present embodiment is not for the scheme of changement.
Embodiment 2:
In Fig. 1; On the basis of embodiment 1; The axle of described sector gear 8 is installed in the chute 12, reversing bar 13 also is installed in the bearing 7, reversing bar 13 upper ends are equipped with bridge joint gear 3; Bridge joint gear 3 is between sector gear 8 and sliding rack 6, and reversing bar 13 is also hinged through pull bar 10 and sector gear 8 near the position of the other end.
The shape of 13 one-tenth bendings of described reversing bar.Described reversing bar 13 is provided with reversing bar axle 16, and reversing bar axle 16 is positioned at the position near chute 12.
The other end of described reversing bar 13 is provided with switching-over button 9, and switching-over button 9 is positioned at arcuate groove 11.
Described sector gear 8 belows are provided with spring; The spring that here is provided with is used to make sector gear 8 to reset, and when bridge joint gear 3 between sector gear 8 and sliding rack 6, and when being in engagement; Can bridge joint gear 3 be compressed, and avoid engagement to throw off.
Described push rod 14 is provided with spring, and the spring that here is provided with is used to make trigger 15 to reset.
The front end of described bearing 7 also is provided with Fixing clamp-seat 1.The Fixing clamp-seat 1 that is provided with can better be fixed the needle tubing of syringe 2.
In the scheme of further optimizing, also be provided with teeth groove 5 on the described sliding rack 6, slide clamp seat 4 cooperates with teeth groove 5 through ratchet mechanism.Cooperate with teeth groove 5 through ratchet mechanism; Can make slide clamp seat 4 along sliding rack 6 slips or locked; When promptly depressing the button on the slide clamp seat 4, cooperate disengagement between ratchet mechanism and the teeth groove 5, this moment, slide clamp seat 4 can slide; And engagement between ratchet mechanism and the teeth groove 5 when unclamping, this moment, slide clamp seat 4 was by locked.
