To be electrical connection；It can be directly connected, the connection inside two elements can also be can be indirectly connected through an intermediary
Or the interaction relationship of two elements, unless otherwise restricted clearly.It for the ordinary skill in the art, can be with
The concrete meaning of above-mentioned term in the present invention is understood as the case may be.
As depicted in figs. 1 and 2, the adjustable blood collecting pen of a kind of depth of needling, including pen cap, penholder 2 and trigger mechanism 3, pen
Cap is assemblied in penholder 2, and blood taking needle trigger mechanism 3 is equipped in penholder 2, and pen cap includes cap seat 12 and can rotate relative to cap seat 12
Cap 11, cap 11 and 12 end of cap seat are linked and packed together；The inner sidewall of cap 11 is fixedly installed annular solid, annular solid
On be provided at least one multi-stage stairs group, the front end of cap seat 12 is fixedly installed the gear muscle matched with multi-stage stairs group,
The outer end of gear muscle leans against in multi-stage stairs group, rotates cap 11, and the outer end of gear muscle is moved in multi-stage stairs group, cap 11
Synchronous rotary connection structure is provided between cap seat 12, cap 11 is provided with needle point with 12 front end of cap seat and portals, specifically makes
Used time, the gear muscle when rotating cap 11, since multi-stage stairs group is during rotation, in multi-stage stairs group and cap seat 12
Mating connection, realize that the gap of the front end of cap 11 and cap seat 12 generates large and small variation.In the ejection process of blood taking needle
In, stroke is the mating connection determination by multi-stage stairs group and gear muscle, i.e., the front end of needle core is before arriving at cap 11
It is blocked when end, when adjusting cap 11 and 12 front space of cap seat are small, needle point exposes length, and piercing depth is on the contrary with regard to big
Depth is pierced into regard to small, to realize the regulatory function for being pierced into depth.
It is wherein provided with position line on cap 12, depth of needling has been oppositely disposed on cap 12 and has been walked around indicating graduation, it should
Graduation mark can be the graduation mark for indicating needle point extension elongation or numerical value or graduation mark and numerical value, this, which is provided with, is conducive to more accurately
Ground adjusts the paracentesis depth of safe blood-taking needle, to adapt to the blood sampling needs of all ages and classes, various types cortex.
Wherein multi-stage stairs group includes the step that multiple axial heights gradually increase, and utilizes the axial height between multi-stage stairs
Degree difference is transmitted by gear muscle, to control the gap precision of flexible cap and cap seat front end, while also having reached control
The needle point of blood taking needle stretches out the precision of cap length, so that the depth of needling of blood collecting pen is adjustable controllable.
Wherein multi-stage stairs group is 3-10 group, the setting of the quantity of multi-stage stairs group be by the practicability of the blood collecting pen,
Processing technology and low aspect at high cost comprehensively consider setting, which has multiple adjustable gears, more conducively root
It needs to select different depth of needling according to the blood sampling of all ages and classes, various types cortex, it is more convenient to use and hommization, example
Such as, the utility model illustrates that the blood collecting pen can carry out five gears by taking Pyatyi step group as an example, when specifically used, one, two grade
Suitable for soft, delicate skin, third gear is suitable for general skin, and four, five grades are suitable for thicker skin.
Wherein the transition face of every grade of step is inclined-plane.As the knob, the transition face on annular solid pushes gear muscle
Outer end, it is more smooth that inclined-plane makes gear muscle from level-one step slide into another grade of step.
Wherein be additionally provided with pin remover on penholder, the pin remover by button 51, pressure cylinder 52 and withdraw of the needle bar 53 connect and
At the middle and back of penholder is equipped with withdraw of the needle slot, and one end of withdraw of the needle bar is arranged in the withdraw of the needle slot, the front end of pressure cylinder and the transmitting
The position of mechanism 3 is corresponding, and the lower end of pressure cylinder 52 is arranged with lower spring.
Pin remover is pushed when the withdraw of the needle, the withdraw of the needle bar 53 on pin remover pushes blood taking needle, so that blood taking needle emits from blood collecting pen
It falls off in 3 inner core of structure, last pin remover also will be returned to initial position under the effect of lower spring.
The application method of the utility model:
Depth of needling is adjusted: cap 11 twisted, drives multi-stage stairs group during rotation when cap 11 rotates, it is multistage
The mating connection of gear muscle in step group and cap seat 12 realizes that the gap of cap 11 and 12 front end of cap seat generates large and small change
Change, the gap size of the front end of adjustment cap 11 and cap seat 12, thus depth of needling when needle point is leant out when realizing blood taking needle transmitting
The purpose of adjusting.Depth of needling is accurately adjusted by outside indicating graduation, and easily operation realizes that adjustment adjusts needle point and exposes
The length of pen both can control needle point to be pierced into skin depth.
Blood sampling: blood taking needle is put into blood collecting pen emitting structural inner core by the pen cap for removing blood collecting pen, removes blood taking needle protection
Then cap covers blood collecting pen pen cap, being directed at the blood sampling site sterilized can be completed blood sampling by lower button.
The withdraw of the needle: after the completion of blood sampling, screwing off blood sampling pen cap, will move back bar needle and pushes forward, and blood taking needle is fallen off in dustbin,
Therefore the problem of blood taking needle is reused is avoided, solves the problems, such as sufferer cross-infection, improves the safety of blood sampling work.
In use, rotation cap 11, makes the position line on scale and cap seat 12 on cap 11 generate displacement, scale shows
It is pierced into the degree of depth, as long as being aligned most shallow when groove 1 for example, in the case where scale 1-5, is aligned most deep when scale 5.
More than, the only preferable specific embodiment of the utility model, but the protection scope of utility model is not limited to
This, anyone skilled in the art within the technical scope disclosed by the utility model, the variation that can be readily occurred in
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with right
Subject to the protection scope of claim.
