Abstract
This utility model provides a kind of single use sterile blood sampler, main body is injector syringe, comprise cylindrical sleeve, piston rod and syringe needle, piston rod is arranged on sleeve inner, barrel forward end is fixedly installed syringe needle, also comprise inner core, inner core is arranged on sleeve inner, inner core exterior contour is identical with barrel bore profile, piston rod is arranged on inner core inside, the unidirectional through hole to the inner conducting of inner core is provided with bottom inner core, unidirectional through hole is closely connected with syringe needle base portion, blood sampling step and blood sample are shifted two large steps to combine, disposablely to complete, effectively avoid because blood sample transports the hidden danger that the blood sample that brings pollutes.In this utility model, inner core top is provided with cylinder holder, by propping up cylinder holder with hands in blood sampling engineering, preventing from causing inner core outwards movement with piston rod activity owing to drawing outside piston rod in blood collection procedure, affecting blood collection.
Description
Technical field:
This utility model relates to a kind of armarium, particularly relates to a kind of single use sterile blood sampler.
Background technology:
Medical test be use modern physics chemical method, a subject that means carry out medical diagnosis, how by experiment room technology, medical instruments and equipment are clinical diagnosis, treatment provides foundation in main research.By systematic learning, we can understand how surveyor blood group, whether anemia, liver function normal etc. to determine a people.This subject requires to use various photoelectric instrument and chemical reagent to complete experimental analysis, so lay particular stress on natural sciences, requires good physics, chemical fundamentals.In one of project that the blood specimen collection of medical test to personnel is comparatively common.
Conventional blood specimen collection adopts common injector syringe to carry out usually, and injector syringe is a kind of common medical instruments, mainly in order to liquid medicine injection or drawing liquid.Common injector syringe is made up of the foraminate syringe of front end band and the piston rod that matches, in use, injector syringe is used for a small amount of liquid or its to be injected into region that other method cannot be close or locally extracts out from those, and therefore injector syringe is commonly employed in medical treatment and nursing.
Along with the continuous progress of current medical level, for medical device sterile, dust-proof requirement is more and more higher, traditional injector syringe, when carrying out blood sampling operation, needs the blood of collection to transfer to blood collection tube, in the process, because syringe needle is carried out secondary use by needs, then bring the hidden danger polluting blood sample, cause assay distortion, such case is also of common occurrence in real life.
Utility model content:
In order to solve the problem, this utility model provides a kind of single use, blood sampling step and blood sample is shifted two large steps and combines, and effectively avoids the technical scheme of the hidden danger of transporting the blood sample pollution brought due to blood sample:
A kind of single use sterile blood sampler, main body is injector syringe, comprises cylindrical sleeve, piston rod and syringe needle, piston rod is arranged on sleeve inner, barrel forward end is fixedly installed syringe needle, also comprises inner core, and inner core is arranged on sleeve inner, inner core exterior contour is identical with barrel bore profile, piston rod is arranged on inner core inside, and be provided with the unidirectional through hole to the inner conducting of inner core bottom inner core, unidirectional through hole is closely connected with syringe needle base portion.
As preferably, inner core length exceedes length sleeve 2 ~ 10mm, and inner core top is provided with cylinder holder, and cylinder holder is fixedly connected with inner core top.
As preferably, arrange sealing ring between sleeve and inner core in gap, described sealing ring is annular, positional distance sleeve top 0 ~ 20mm.
As preferably, inner core outer surface is provided with graduation mark.
The beneficial effects of the utility model are:
(1) this utility model also comprises inner core, and inner core is arranged on sleeve inner, blood sampling step and blood sample is shifted two large steps and combines, and disposablely completes, and effectively avoids because blood sample transports the hidden danger that the blood sample that brings pollutes.
(2) in this utility model, inner core top is provided with cylinder holder, by propping up cylinder holder with hands in blood sampling engineering, preventing from causing inner core outwards movement with piston rod activity owing to drawing outside piston rod in blood collection procedure, affecting blood collection.
(3) arrange sealing ring in gap between sleeve and inner core, ensure the single use of this hemostix, while taking out outer tube, sealing ring will be taken out of sleeve inner, and this equipment cannot be reused.
(4) in this utility model, inner core outer surface is provided with graduation mark, can be recognized the capacity of blood in inner core by graduation mark accurately, simple and convenient.
Accompanying drawing illustrates:
Fig. 1 is this utility model structural representation.
Detailed description of the invention:
For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As Fig. 1, shown in Fig. 2, single use sterile blood sampler, main body is injector syringe, comprise cylindrical sleeve 1, piston rod 2 and syringe needle 3, it is inner that piston rod 2 is arranged on sleeve 1, and sleeve 1 front end is fixedly installed syringe needle 3, also comprises inner core 4, it is inner that inner core 4 is arranged on sleeve 1, inner core 4 exterior contour is identical with sleeve 1 inner chamber profile, and it is inner that piston rod 2 is arranged on inner core 4, is provided with the unidirectional through hole 5 to the inner conducting of inner core 4 bottom inner core 4, unidirectional through hole 5 is closely connected with syringe needle 3 base portion, reaches and gets final product the effect that blood sample collection can realize blood sample safe transit simultaneously.Blood sampling step and blood sample are shifted two large steps to combine, disposablely to complete, effectively avoid because blood sample transports the hidden danger that the blood sample that brings pollutes.
And, inner core 4 length exceedes sleeve 1 length 5mm in the present embodiment, inner core top is provided with cylinder holder 6, cylinder holder 6 is fixedly connected with inner core 4 top, by propping up cylinder holder 6 with hands in blood sampling engineering, prevent from causing inner core 4 outwards movement with piston rod 2 activity owing to drawing outside piston rod 2 in blood collection procedure, affect blood collection.Between sleeve 1 and inner core 4, in gap, sealing ring 7 is set, sealing ring 7 is annular, and positional distance sleeve 1 top 10mm, ensures the single use of this hemostix, while taking out outside inner core 4, sealing ring 7 will be taken out of sleeve 1 inside, and this equipment cannot be reused.Meanwhile, inner core 4 outer surface is provided with graduation mark 8, can be recognized the capacity of blood in inner core 4 by graduation mark 8 accurately, simple and convenient.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of this utility model patent.
