[technical field]
The present invention relates to the technical field of the technical field of medical apparatus and instruments, particularly peripheral blood sampling device.
[background technology]
Blood test be hospital therapy patient through frequently with medical measure, during adult's blood drawing, existing major part uses vacuum to adopt
Blood vessel or disposable syringe vein haemospasia, and infant and old people are because blood vessel is relatively thin or inconvenient activity often gathers end slightly
Blood, there are three kinds of methods in current most of hospitals when carrying out these work: 1, use anticoagulant test tube scraping Blood Law；2, weight is used
Power thick plastic tube drainage；3, two-step method collection, first with after disposable glass micro blood-taking tube draw blood add anticoagulant tube or
In Bei.Complex operation when using the 1st kind of method, operator need to frequently open, close cap test tube, and when scraping, blood can be stained with
Dye test tube mouth, wall cause the error of assay, and are easily infected with medical personnel.Use second method because of use gravitational method, its
Requirement to position is higher, stores up blood vessel and must be placed in 5 centimeters below blood sampling site during blood sampling, for being in hospital or bed patient
The most difficult collection, and as pipe having bubble then cannot gather during blood sampling.3rd kind of method uses two-step method, operates more loaded down with trivial details, and
And disposably glass micro blood-taking tube is easy to fracture, easily causes failure and the pollution of blood sampling.Health ministry is also related to pre-
The instruction of anti-nosocomial infection, clearly proposes to accomplish " people one pin one is managed a piece of " time slightly blood sampling in end, and " pipe " here is exactly
Refer to that everyone uses a blood taking tube or blood collecting containers.
[summary of the invention]
The purpose of the present invention solves the problems of the prior art exactly, proposes a kind of negative pressure tip blood sample easy to use and adopts

Cross cross recess center.
As preferably, described through hole and the most big up and small down truncated cone of sealing-plug, sealing-plug is tight with the sidewall of through hole
Contiguity is touched.
As preferably, there are some circle retainer ring, retainer ring embedding sealing in the position that described suction pipe contacts with sealing-plug
In plug.
As preferably, described storage blood vessel top exterior walls is provided with external screw thread, and lid is provided with in matching with external screw thread
Screw thread.
As preferably, described storage blood vessel is made up of the fixed part being from up to down sequentially connected, transition part and storage blood portion, stores up blood
Portion's external diameter is less than fixed part external diameter, transition part connecting portion and storage blood portion.
As preferably, described first passage is positioned at the top in storage blood portion, and the bottom level height of suction pipe leads to less than first
The level height of pore.
As preferably, described second passage is positioned at the bottom of spring-backed quill, can automatically restore after spring-backed quill deformation.
Beneficial effects of the present invention: the present invention, by being arranged in lid by the elastic sealing gasket with cross recess, makes
Blood vessel must be stored up and have a good sealing, the collection of blood sample simultaneously and need not remove lid when taking out；The setting of sealing-plug makes
Storage blood vessel has good sealing, prevents outside air from polluting blood sample；The setting of spring-backed quill makes to store up the easy shape of Ink vessel transfusing
Become negative pressure, be conducive to adding blood sample to storage Ink vessel transfusing.
Inventive feature and advantage will combine accompanying drawing by embodiment and be described in detail.
