With reference to the accompanying drawings and examples scheme of the present utility model is done with further details of explanation and explanation.
Specific embodiment
Defer to technique scheme, back springing type blood lancet device of the present utility model, including cylinder 2, peace in described cylinder 2
Equipped with shifter, one end of described cylinder 2 is removably provided with shank 3；Described shifter connects multiple being vertically arranged
Connecting rod 6, the end of each described connecting rod 6 is all movably installed with a blood taking needle 4；Described blood taking needle 4 stretches into shank 3
Interior, its end can be passed by shank 3 end.
The described shifter shifter alternately flexible with controlling multiple pen cores in Multi-refill ball-point pen in prior art is identical,
Specifically include draw runner 1 and spring 5 etc., described cylinder 2 side wall is provided with slide rail, described draw runner 1 can slide along slide rail；Described bullet
Spring 5 is sleeved in connecting rod 6, by controlling the motion of Sliding Control connecting rod 6 in the vertical direction of draw runner 1, thus controlling
The motion of blood taking needle 4 in the vertical direction is so that when medical personnel need to be taken a blood sample using blood taking needle 4, control shifter
Make one of blood taking needle 4 pass shank 3, puncture human body skin；After finishing, shifter is controlled to make blood taking needle retraction pin
Inside bar 3.Blood lancet device of the present utility model is easy to use, flexible operation.
Specifically, described shank 3 includes the body of rod 301, inside the described body of rod 301, its axis direction is provided with multiple passages
302, described blood taking needle 4 is located in passage 302；The described body of rod 301 upper end is coaxially arranged with a connecting cylinder 303, described connecting cylinder
303 insert inside described cylinder 2.
The plurality of blood taking needle 4 is corresponded with described passage 302, after one of blood taking needle 4 is using finishing, you can
In its corresponding passage 302 of retraction, without polluting untapped blood taking needle 4 in other passages 302；Described connecting cylinder 303 makes
Obtain the body of rod 301 and cylinder 2 easy installation and removal, be easy to manufacturing of device of the present utility model.
Alternatively, described blood taking needle 4 and connecting rod 6 are spirally connected.After multiple blood taking needles 4 all use, replaceable blood taking needle 4,
It is easy to device recycling of the present utility model, thus cost-effective.
Alternatively, described connecting rod 6 is circumferentially symmetrically arranged with 2～4, and corresponding blood taking needle 4 is provided with 2～4
Individual, in the same manner, described passage 302 is correspondingly arranged on 2～4.The number of connecting rod 6 can be selected according to using needs.
