Description
Technical field
The present invention relates to medical domains, and in particular to a kind of dedicated bellows blood-taking device of Inherited Metabolic Disorders detection.
Background technique
When metabolic disease is that obstacle occurs for Biochemical processes in vivo, certain metabolites such as sugar, fat, protein, fast
Disease caused by the accumulation such as purine, calcium copper or shortage.Symptoms of varying severity, diagnosis rely on the bioids such as clinical manifestation and blood, urine
It learns and checks.It is a kind of simple, quick and cheap blood cake examination for newborn's Inherited Metabolic Disorders inspection that Inherited Metabolic Disorders detection, which refers to,
It tests.It can find whether child suffers from congenital hereditary disease early by this screening, and timely be treated, make its health
Growth.The test of heredity metabolism is made a definite diagnosis using equipment, medicinal agents and using specific biochemical medicine detection method auxiliary.Sample
Originally venous blood or dried blood spot are mostly used, can detect macromolecular class Inherited Metabolic Disorders and small molecule class Inherited Metabolic Disorders.
In clinic, children's hospital is generally using that can drip the three blood collecting card progress sampling operations bled, by the blood of infant
Drop is to being labeled on the blood collecting card of the relevant informations such as name, gender, it is desirable that the Blood piece of blood collecting card must completely after natural drying
It seals again, with inspection after the sealing of sterile sealing bag.Since disposable vein blood taking needle cooperation transparent hose can not be controllable by blood
Property drip on blood collecting card, therefore, the traditional way of the blood collection procedure of entire blood sample be using syringe punctures again extract one
Quantitative blood.This traditional way haves the defects that certain: firstly, using the process of blood collection needle, needing to patient
It is punctured, and extracts a certain amount of blood, the blood demand for the blood collecting card bled by clinical practice, discovery three is 1 milli
It rises, when extracting blood by syringe, is often difficult to control, causes blood volume decimated more, cause unnecessary waste；Its
It is secondary, it is also more troublesome using the process that syringe extracts blood, operation difficulty and coefficient of performance are higher, cannot be disposable as using
It is easily operated like that vein blood taking needle extracts blood, and directly take intravenous injector blood sampling to have not to be able to satisfy blood smoothly controllable
Ooze, therefore traditional method be all made of at present syringe extract blood；In addition, using syringe wash away required blood volume it
Afterwards, medical staff needs to drip to the blood of extraction on the blood collecting card that three bleed, which is the directly hand-held injection of medical staff
Device is operated, and there is also certain risks for process, other than be easy to causeing blood to pollute, also likely to operator
Member causes certain injury, and the careless slightly piercing needle that will result in is stabbed, and causes infection and unnecessary trouble, causes simultaneously
The wasting of resources of disposable syringe is also applied with certain pressure for hospital's recycling operation.
Therefore, it is simple to produce a kind of structure, simple to operate, work and operational efficiency are high, and blood volume extraction control is accurate,
It is strong to extract and ooze controllability, mating disposable vein blood taking needle uses, and effectively saves syringe needle and syringe cost, efficiently prevents
Needle is stabbed, and safety coefficient is high, ingenious in design, reduces operation difficulty, and the Inherited Metabolic Disorders of clean hygiene detect dedicated bellows blood sampling
Device has extensive market prospects.
Summary of the invention
In view of the deficiencies of the prior art, it is simple to provide a kind of structure by the present invention, simple to operate, work and operational efficiency
Height, it is accurate that blood volume extracts control, extracts and ooze that controllability is strong, and mating disposable vein blood taking needle uses, effectively saving syringe needle
With syringe cost, efficiently prevent needle from stabbing, safety coefficient is high, and it is ingenious in design, reduce operation difficulty, the hereditary generation of clean hygiene
It declines office, invitation, etc. on account of illness and detects dedicated bellows blood-taking device, for overcoming defect in the prior art.
The technical scheme is that be achieved: a kind of dedicated bellows blood-taking device of Inherited Metabolic Disorders detection, including it is negative

It offers and the valve block of pipe is stopped to stop pipe mounting hole for installing valve block, it is defeated that valve block stops pipe by sealant to be fixedly mounted on this
Enter in check valve mounting hole.
The capacity of the negative pressure gasbag is one milliliter, and negative pressure gasbag is made of transparent plastics material.
The present invention has following good effect: this product is easy to operate, and work and operational efficiency are high, firstly, overcoming
Many defects of traditional process using blood collection needle, make to extract three and bleed and drip to the process of blood collecting card and become simply to have grasped
Make, uppity defect, can be accurately controlled blood drawing amount, guarantee few extract when avoiding through syringe extraction blood
The blood of patient；Secondly, this product operating process is simple to operation, operation difficulty degree is low, can take a blood sample as disposable vein
Needle operates extraction blood like that, and whole process controllability is strong, can be smoothly by the blood of extraction after extracting blood
It drips on the blood collecting card that three bleed, the operation that oozes of blood is made to become can control, it is smoothly controllable that blood sampling volume is able to satisfy blood
It oozes, therefore traditional syringe can be substituted and extract blood；In addition, using this product can effectively save syringe needle and
The cost of syringe, and during whole operation, it is after removing vein blood taking needle during oozing extraction blood
Operation, therefore medical staff can be protected, the generation that needle stabs phenomenon is placed, clean hygiene is at low cost, is easy to control
System, not easy infection and pollution, while being conducive to the completion of hospital's recycling operation.
