Background technique
Blood collecting pen is used cooperatively with disposable sterilized blood taking needle, acquires the blood sample of human body tip.In use, it needs
Blood taking needle is placed in blood collecting pen, then blood taking needle cap is removed, exposed needle point holds very much under the premise of non-lid pen cover during this
Finger easily is punctured, while also it is easy to appear cross-infections, there are security risks to user；Blood collecting pen is in continuous blood collection procedure
In it is cumbersome, and blood taking needle is many kinds of, poor universality.And although existing An Caizhen product does not need the blood collecting pen that matches,
Can directly blood was collected, but due to it is existing peace adopt needle body product it is larger, also needed in blood collection procedure extract protective cap, press
Press trigger mechanism；And trigger mechanism is easily triggered, there are the danger of maloperation；Also inconvenient to carry simultaneously.
The patent of Publication No. CN106264561A proposes a kind of side trigger-type hemostix, plays nothing by aluminium foil overlay film
The effect of nectar envelope so, can be straight without pulling up blood taking needle protective cap when blood sampling it is not necessary that protection structure is arranged to syringe needle
Connecing puncture aluminium foil, blood was collected, simplifies structure, improves its safety.But foil sealing hinders bacterium effect and people complies with one's wishes not to the utmost, this
It is great defect for medical device product, and the toughness of aluminium foil is poor, is easy to be missed during transporting storage
It punctures, reduces yield rate.
Utility model technical solution
The technical problem to be solved by the present invention is to overcome drawbacks described above existing for well-known technique, and provide blood sampling
Device, it is intended in the case where not influencing blood taking needle normal work, improve its sealing effect, prevent cross-infection, improve hemostix
Yield rate, and simple process, convenient transport, security performance are more preferable.
The utility model is achieved through the following technical solutions, according to a kind of hemostix provided by the utility model, packet
Shell is included, blood taking needle and trigger mechanism are equipped in the shell, blood taking needle is projected by trigger mechanism, is pierced into skin, the shell
Body is equipped with needle outlet perpendicular to the side of blood taking needle, and side is equipped with triggering mouth, is equipped with therewith between the needle outlet and triggering mouth
The link slot of connection, needle outlet, triggering mouth are sealed by the flexible seals of integral structure, and the flexible seals are moulded in shell
On body.
Preferably, the needle outlet is externally provided with external wall, and contact face between the two forms the first table top, shell side
Face is equipped with groove, and bottom portion of groove is equipped with triggering mouth, triggers and forms the second table top between mouth and groove floor, the surface of shell is set
There is link slot, link slot is connected to needle outlet and triggering mouth.
Preferably, the flexible seals include puncture portion and trigger unit, and puncture portion is set at needle outlet, and trigger unit is set to
It triggers at mouth, puncture portion edge upwardly extends to form wall body, and wall body top extends outward to form flange, the trigger unit side
Edge extends outwardly for outer rim, and trigger unit center ecto-entad forms the recess of gradual change, passes through one between trigger unit and puncture portion
The connection strap of structure connects, and connection strap is set in link slot.
Preferably, the puncture portion is with a thickness of 0.1-2mm.
Preferably, the puncture portion is with a thickness of 0.5mm.
Preferably, the flexible seals Rockwell hardness is lower than 90.
Preferably, the flexible seals Rockwell hardness is 40.
Preferably, the flexible seals are silica gel material.
Preferably, flexible seals and shell use double-shot moulding.
Preferably, flexible seals and shell use quadric injection mould.
The utility model sealing is tight, ensure that and hinders bacterium in storing process, and blood taking needle is not necessarily to that protective cap is arranged at syringe needle；
The operation for extracing protective cap is omitted in blood collection procedure, directly carries out puncture blood sampling, and which simplify operating procedures, improve and use
The safety of person；It is sealed compared to foil class, the utility model uses flexible sealing (such as flexible glue), cooperates shell structure, close
It is more preferable to seal effect, is less prone to breakage, improves yield rate；The trigger unit of flexible seals is pressing position, is arranged for recess,
Ductility is more preferable, has both guaranteed pressing triggering trigger mechanism, has also guaranteed its fastness, meanwhile, user needs in use
Applying certain power could trigger, and reduce maloperation, reduce scrappage；Face is pierced through again very while guaranteeing sealing in puncture portion
It is thin, guarantee to pierce through effect；Link slot connects needle outlet and triggering mouth, guarantees the implementation of Shooting Technique；In continuous blood collection procedure
It is easy to operate, it is convenient for carrying.In conclusion the utility model is compared with prior art, sealing effect is more preferable, prevents from intersecting and feel
Dye, improves the yield rate of blood-taking device, and simple process, convenient transport, security performance are more preferable.
