Abstract
The invention discloses a blood collection pen which is provided with a dual-spring lancet bracket, wherein the bracket can be mounted in a pen housing, can slide up and down in the pen housing and is used for bearing a disposable lancet or a disposable needle. A bracket sliding part in a slot in the inner side of the pen housing is moved back to prepare ejection of the disposable lancet or the disposable needle, and the lancet or the needle can be instantly ejected to an appointed position after a trigger button is pressed down and then returns to the original position under the action of springs. Therefore, the micro blood collection operation can be carried out, the whole prick and blood collection process can be finished in a very short time, and a patient does not feel pain. The blood collection pen is simple in structure and convenient and reliable to use and produce.
Description
Technical field:
Patent of the present invention relates to technical field of medical, and a kind of blood sampling instrument that uses in medical diagnosis and individual blood testing specifically can change the blood collecting pen of disposable blood taking needle or disposable use syringe needle.
Background technology:
At present, blood collecting pen has multiple mode on the market, is the ejection mechanism of utilizing spring mostly, blood taking needle is applied ejection force, thereby prick skin is finished blood sampling.The ejection type blood collecting pen is a kind of comparatively advanced employing utensil, has and waits advantage easily and fast.
US6022366 discloses a kind of blood taking instrument, and wherein, the length of blood taking needle clamper can be suitable for regulating thrusts the degree of depth.But the cap of housing must be at first removed in this requirement, and what be associated therewith is to be difficult to use in a lot of user.And this exists user to be present in the risk that the blood taking needle in the device injures.
And the present invention is directed to blood collecting pen when drawing pin to arrive location preparation percussion point, a punch block generally is set in a body and Return spring seat and the medicated cap of pulling back are set on the top, utilize external force to carry out punch block and the mode that Return spring seat and the medicated cap of pulling back retract pin is set on the top syringe needle is applied the dynamics of launching, concrete operations are: penholder is connected with blood taking needle, retract or pull punch block compression spring is excited during to certain position, when pressing when exciting button, the elastic force of spring ejects blood taking needle moment to the position that configures in advance, borrow the spring coherence to retract former ejected position, thereby reach the purpose of prick skin and safety blood taking.
Summary of the invention:
The object of the present invention is to provide blood collecting pen, it is simple and reasonable, and manufacturing process is simple, and processing step is few, can effectively control cost, and product just use stability higher, overcome some shortcomings of the prior art.
To achieve these goals, technical scheme of the present invention is blood collecting pen, and it mainly comprises nib (1); Preceding regulating sleeve (2); Back adjustment seat (3); Blood taking needle (pin); Left cap (4); Punch block (5); Excite button (6); Right cap (7); The preceding spring (8) that ejects; Return spring (9); Return spring seat (10); The medicated cap (11) of pulling back; Interchangeable straight tube head (12); Guide chute (13) in the left and right side cap; Pull the trigger shell fragment (14) on the punch block; Chamfer triangle trigger post (15) in the left and right side cap; The movable bolt (16) of button is characterized in that: described, nib (1) and preceding regulating sleeve (2) and back adjustment seat (3) but form the adjusting nib of left rotation and right rotation adjusting blood taking needle (pin) the acupuncture depth; Disposable blood taking needle (pin) is put into the dress syringe that punch block (5) is gone up front end, there is round head can block Return spring seat (10) and orientable the moving up and down of adorning Return spring (9) and punch block (5) rear end is shaped as the vertical bar shape and can be inserted in the preceding spring (8) that ejects at least significant end, and together together with exciting button (6) the directed left cap of packing into (4) and right cap (7) lining, the internal diameter cover of medicated cap (11) of will pulling back at last advances left cap (4) and right cap (7) rear end and orientable moving up and down, and be provided with draw-in groove in the medicated cap of pulling back (11) and Return spring seat (10) outer ring has chimb to block close-fitting fully, form complete body.In use, will regulate nib earlier and open with a body rotation, disposable blood taking needle (pin) will be put into the dress syringe that punch block (5) is gone up front end, after the spiral cover readjustment joint nib, retract medicated cap (11), disposable blood taking needle (pin) will be in the state of being excited; Press and excite the disposable blood taking needle of button (6) (pin) compressed because of the preceding ejection spring (8) on the punch block (5), the elastic force of spring ejects blood taking needle moment to the position that configures in advance, borrow the spring coherence to retract former ejected position, thereby reach the purpose of prick skin and safety blood taking.
The design concept that the present invention breaks general blood collecting pen has two; One, for punch block (5) stage casing have establish eject before the external diameter step can withstand spring (8) punch block (5) rear end be shaped as the vertical bar shape and can be inserted in before eject spring (8) and have round head can block Return spring seat (10) and orientable the moving up and down of adorning Return spring (9) at least significant end.They are two years old, in left cap (4) and right cap (7) middle part oval breach is arranged respectively half, the movable bolt (16) that there is a button on half each limit of oval breach inside front is respectively arranged for can be up and down at left cap (4) and right cap (7) middle part, and the inside excites button (6) and chamfer triangle trigger post (15) under respectively there is half oval breach at left cap (4) and right cap (7) middle part; There is percussion shell fragment (14) that a L shaped groove is arranged at punch block (5); Excite button (6) to see that from the cross section picture is humanoid prone position form, there is a shell fragment to be placed on below and excites button (6) seat, exciting button (6) head to be fixed on can be up and down on the movable bolt (16), and its structure has certain elasticity, and afterbody relies on mutually with percussion shell fragment (14) on its punch block.When operation, pull back medicated cap (11) toward post-tensioning, drive all parts of punch block (5) and also walk back the preceding spring (8) that ejects of compression simultaneously to assigned address, and percussion shell fragment (14) the L. shape groove on the punch block (5) also snaps on the chamfer triangle trigger post (15), finishes state to be excited.When exciting, press and excite button (6), its afterbody with the percussion shell fragment (14) on the punch block after press down down the height of operating range greater than chamfer triangle trigger post (15), because of the relation of preceding ejection spring (8) compression, moment drives all parts of punch block (5) and ejects with disposable blood taking needle (pin) that moment retracts former ejected position by means of the spring coherence again to the position that configures in advance.Its principle, effectively reduce producting process difficulty, reduce processing step, shorten activity time, enhance productivity, effective control production cost, the advantage reasonable in design, practical with excitation structure, this product of pulling back is: reasonable in design, safe, the manufacturing process difficulty is low, operation is few, save cost, be easy to produce, be easy to popularization.
