Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of safe blood-taking needle without single packing bag.
Background technique
Blood taking needle or transfusion needle are one of maximum medical device products of current global sales.However, existing blood sampling
Needle has the disadvantage that
1. blood taking needle needs to pack blood taking needle and sealed with inner wrapping such as plastics or paper small package bag after being completed
It sterilizes after mouthful；Before carrying out EO sterilizing, blood taking needle is to carry out joint sealing after inner wrapping, middle packaging, big packaging, is being sent
Enter in sterilizing cabinet and sterilize, when sterilizing, EO gas will penetrate blood taking needle sealed package, closed blood taking needle sleeve enters blood sampling
Pin inner chamber kills its internal bacterium, and blood taking needle needs to place a period of time after the completion of sterilizing, to dissipate EO sterilizing gas,
Emissioning time is generally 15 days.Such blood sampling needle construction, the time for distributing sterilization gas is long, causes the finished product manufacturing cycle
It is long, and some EO gas residues are still had in product after 15 days distribute, in use, medical worker's suction body can be made
It is interior, it is detrimental to health.
2. after blood taking needle use, medical staff is usually whipped to throw away, due to the winding the needle tube syringe needle of blood taking needle it is exposed
Outside, it is easy to stab medical staff or garbage disposal staff.Countries in the world hospital stabs medical care people because of the syringe needle after at present
Millions of examples occur every year for the injury accident of member, are especially pricked with hepatitis B and the used syringe needle of Ai Zi disease Virus patients
Wound, seriously compromises the physical and mental health of medical staff, because of the huge treatment cost of infection, serious warp can be also caused to medical staff
Ji burden.
Summary of the invention
To solve the problems, such as that existing blood taking needle or transfusion needle need small package bag, sterilizing gas emissioning time long, this hair
It is bright that a kind of safe blood-taking needle without single packing bag is provided.
The object of the present invention is achieved in the following manner:
A kind of safe blood-taking needle without single packing bag, including needle guard 1, winding the needle tube 2, upper needle stand 3, lower needle stand 5, shell 6, knit stitch
Pipe 7, pipe sleeve 8 and sheath 9, winding the needle tube 2, upper needle stand 3, lower needle stand 5 are sequentially fixedly connected with lower needle tubing 7, are formed and are flowed for blood sample
Inner cavity；Needle guard 1 is socketed in 3 upper end of needle stand, and lower 5 head of needle stand is socketed with pipe sleeve 8, and sheath 9 is socketed on the middle waist of lower needle stand 5
Threaded portion, upper needle stand 3 are socketed with shell 6 outside, and 6 bottom end of shell is fixed on lower needle stand 5, and 1 upper end of needle guard is equipped with fungi-proofing
Air film 11, the needle guard 1, upper needle stand 3, lower needle stand 5 and sheath 9 form a shielding harness for preventing bacterium from invading.
The shell 6 is equipped with groove II 62, and spring 61 is equipped in groove II 62, and the length of groove II 62 is greater than spring 61
Length, 61 lower end of spring is installed on shell 6, and upper end is free end and extends into shell 6；The upper needle stand 3 and shell 6
Between be arranged with protective case 4, the upper end edge shell 6 of protective case 4 stretches out, and the bottom edge of protective case 4 is with outward extension outer
The thickness of boss 42, outer lug boss 42 is less than the distance between 61 upper end of spring and 62 upper end inner wall of groove II.
The groove II 62 is two, is separately positioned on the opposition side of shell 6.
It is equipped with inner convex platform 41 close to upper end on 4 inner wall of protective case, the upper needle stand 3 is equipped with and 41 phase card of inner convex platform
The groove I 31 connect.
The shell 6 is rectangular parallelepiped structure, and spring 61 is integrally formed with shell 6.
The fungi-proofing ventilated membrane 11 of 1 upper end of needle guard is that the membrane material made of high molecular material is logical when membrane material is sheet
It crosses heat seal or cap is pressed together on 1 upper end of needle guard；When membrane material is column, the upper end in needle guard 1 is filled in.
The 6 lower section outer wall of shell is equipped with concave and convex stripe 63.
Compared with the existing technology, advantages of the present invention is as follows:
1. needle guard, upper needle stand, lower needle stand and sheath form a shielding harness that can prevent bacterium from invading, remove product inner wrapping from,
It can directly be loaded into middle box or middle packaging bag, so that EO sterilizing gas is easily entered product cavity and kill bacterium, raising is gone out
Bacterium effect, while reducing the wasting of resources；Similarly, it is carried out the parsing phase in product, EO sterilizing gas is easy to dissipate from the inside of product
It sends out, shortens EO sterilizing gas and parse the phase, avoid injury of the EO sterilizing gas to hospitalized patients.
2. and on blood taking needle ontology be embedded in protective case, after blood taking needle use, medical staff need to only pull out guarantor
Sheath, protective case are in outside needle tubing and fixed, form insulation blocking to winding the needle tube, prevent exposed winding the needle tube syringe needle from stabbing
Other people, prevent from stabbing infection, realize safe retrieving blood taking needle.
