Abstract
The utility model discloses an auto vacuum blood collecting instrument, belonging to a blood sampling device, made of nontoxic transparent or semitransparent medical plastic, common rubber and the raw material of stainless steel. The auto vacuum blood collecting instrument mainly comprises a blood-containing tube, a rubber cover cap, a sleeve tube and a needle head. The technique uses the method of vacuum negative pressure to suck the blood into the blood-containing tube for direct test. The extracted blood is not need to be injected into the test tube, the operating program is saved, and the raw material of the needle core portion of an injector is saved. The utility model has the advantages of low cost and convenient operation. The auto vacuum blood collecting instrument can replace the blood-collecting method of the traditional injector.
Description
This utility model belongs to blood sampling device.
The method of the blood sampling of Clinical Laboratory at present is that the blood sampling personnel could extract blood out with pulling the pin stamen, blood is injected in vitro can inspect by ready samples again with the disposable syringe blood sampling.The method operation sequence is various, sterile working's difficulty, and the expense height, and each venous blood collection can only obtain a specimen.
The objective of the invention is for provide a kind of easy and simple to handle, save syringe needle stamen part, be convenient to the vacuum automatic blood sampler preserving and carry.Another object of the present invention is can get many parts of blood specimens continuously for a venipuncture.Therefore the present invention has any different in prior art.
For realizing above-mentioned design, intend the vacuum automatic blood sampler that adopts nontoxic transparent or semitransparent medical plastic and rustless steel to make.
Below in conjunction with accompanying drawing construction features of the present invention is further described:
Fig. 1 is a front cross-sectional view of the present invention
Fig. 2 is the top view profile of Fig. 1
The appearance blood vessel (1) of vacuum automatic blood sampler is general small test tube, can adopt translucent or transparent medical grade plastic is a raw material, and holding blood vessel (1) total length and be 100mm, wall thickness and be 1mm, outer wall, to indicate the every 0.5ml of 1ml to 5ml be the containing mark of a class.Rubber block (2) adopts General Purpose Rubber hot-forming, to be that the thick 1mm in edge, center are thin be easy to by inboard punctures for 0.05mm at its top, rubber block (2) wall is high for 10mm, wall thickness are 1mm, and its inwall is close to and is held blood vessel (1) mouth of pipe outer wall, makes it to seal air tight.Sleeve pipe (3) is made with nontoxic transparent or semitransparent medical plastic, sleeve pipe (3) total length is 61mm, wall thickness 1mm internal diameter is 17mm, collar extension has the anti-limit (7) of long 3mm, high 2mm to be convenient to the medical worker to hold operation, sleeve pipe (3) the thick 2mm in top, it is that 5mm, hollow are 1mm for the 15mm diameter that center of top has total length, is that the boundary is divided into inside and outside two parts with sleeve pipe (3) Cylinder connected vertically (5) and with it with the sleeve pipe top, inside is 3mm, and the outside is 10mm.Syringe needle is divided into outside syringe needle (4) total length 35mm and inboard syringe needle (8) total length is 15mm.Outside syringe needle (4) 5mm is bumped into the outside central authorities of Cylinder (5), inboard syringe needle (8) 3mm is bumped into the central interior of Cylinder (5), leave cavity between the interior outside syringe needle in the Cylinder (5) and observe the blood back situation when being convenient to adopt blood for the observation window (6) of long 5mm, above-mentioned sleeve pipe (3) Cylinder (5) outside syringe needle (4) interior outside syringe needle (8) is the casting one all.
The utility model is its advantage compared with the prior art:
1. reduced after the blood sampling and blood to have been injected in vitro this operation link and saved a simultaneously venipuncture of material of manufacturing test tube and can get continuously many parts of blood specimens.
2. avoided polluting and provide convenience, reliable condition for sterile working.
Prepare the method for holding interior the negative pressure of vacuum of blood vessel (1) and be with hold blood vessel (1) or be added with the appearance blood vessel (1) of a certain amount of anti-coagulants and rubber block a shot (2) together put into super-clean bench, use negative pressure pump to find time to make negative pressure in the super-clean bench, rubber block (2) is enclosed within holds blood vessel (1) mouth of pipe, make it to hold in the blood vessel (1) and be negative pressure of vacuum. Then, will wear the appearance blood vessel (1) of rubber block (2) and with the sleeve pipe (3) of fixed needle together through the sterilization of isotope radiation sterilization, it is for subsequent use to put into aseptic plastic bag after the sterilization.
When getting blood, hand-held sleeve pipe (3) thrusts blood vessel with outside syringe needle (4) sees blood back by observation window (6), the appearance blood vessel (1) that will wear rubber block (2) inserts in the sleeve pipe (3), make the inboard syringe needle of sleeve pipe (3) (8) puncture rubber block (2), utilize appearance interior negative pressure of blood vessel (1) and the pressure of blood vessel own that blood is sucked and hold blood vessel (1).Gather many parts of specimen as need, then can extract out hold blood vessel (1) reuse other, thereafter syringe needle in the blood vessel is extracted out, take out sleeve pipe (3) content blood vessel (1) censorship.
It is low that the utility model is manufactured cost, easy to use, the tight sampling of sterilization is aseptic, can do various clinical examinations blood samplings for each big medical colleges and schools, each hospital scientific research unit and use, and is particularly suitable for health clinics in towns and townships and outlying mountain area commune hospital and passes on large hospital or inspection center and do complicated the check.
Claims (3)
1, a kind of vacuum automatic blood sampler is with it is characterized in that nontoxic transparent or semitransparent plastics are made, this hemostix is formed by holding blood vessel (1) rubber block (2) sleeve pipe (3).
