Abstract
The utility model relates to a collection tool for taking samples of venous blood, which is composed of a needle tube (1), a needle seat (2), a rubber tube (3), a bracket (4), a test-tube rubber plug (5) and a test tube (6). The utility model has the advantages of good safe performance, simple and convenient operation, and high testing correct rate.
Description
This utility model relates to a kind of medical apparatus, especially a kind of venous samples can sampling instrument.
For a long time, the venous samples can sampling instrument of medical department use is combination or the disposable syringe and the combination of the teat glass of use repeatedly of disposable syringe and disposable test tube.The blood sampling program is: the chemist extracts a certain amount of venous samples can with disposable syringe from human body earlier, then the blood sample in the syringe is expelled in vitro.This traditional venous samples can sampling instrument shortcoming is a lot: at first, security reliability is poor, no matter be that disposable test tube or the teat glass that uses repeatedly all are the open type test tube, not from capping, and the chemist will shift blood sample one time from syringe, the chemist very easily adheres to blood sample like this, and is infected easily; Secondly, use inconvenience, to all inconvenience of transportation of shifting blood sample repeatedly and filling the blood sample test tube; Can influence the correctness of check in addition exactly, the invisible spectro blood sample of open type is contaminated easily, and when syringe is transferred to test tube with blood sample, if push the too quickly hemocyte breakage that causes easily, produces haemolysis, can influence the correctness of check like this.
The purpose of this utility model is to overcome above shortcoming, provides a kind of security reliability good, easy and simple to handle, check accuracy high disposable use venous samples can harvester, and it can be automatically, quantitatively take a blood sample, and directly enter test tube.
The purpose of this utility model is to realize like this; This disposable use venous samples can harvester is made up of needle tubing, needle stand, sebific duct, support, test tube plug and test tube.Needle tubing is the needle tubing with two needle point that medical stainless steel pipe special-purpose machinery processes; Needle stand has female thread to be used for fixing needle tubing; Glue pipe socket prevents blood back on of needle tubing; Support is used for fixing needle stand and test tube; The test tube plug is used for sealing test tube and guarantees invisible spectro negative pressure; Test tube is used to deposit blood sample.Invisible spectro quantitative negative pressure can set in advance in the maker special purpose machinery, also can before using, hospital be provided with special purpose machinery, the amount of negative pressure is provided with according to the amount of institute's blood sampling, is different as its negative pressure amounts of test tube of the test tube of desirable 5 milliliters of blood samples and desirable 10 milliliters of blood samples.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the profile of disposable use venous samples can harvester.
In Fig. 1, needle tubing 1 is fixed on the support 4 through needle stand 2, and sebific duct 3 is enclosed within on the needle tubing 1 in the support 4, sets in the test tube 6 after a certain amount of negative pressure with 5 sealings of test tube plug, push then in the support 4, and make needle tubing 1 in support 4 penetrate test tube plug 5.
During blood sample collection, the chemist inserts needle tubing 1 in the human vein, because negative pressure is in vitro arranged, venous blood is flowed directly in the test tube 6 by needle tubing 1 automatically, and the blood sample amount that is extracted is by negative pressure amount decision in vitro, when the amount of taking a blood sample reaches requirement, just can extract the test tube plug 5 of test tube 6 together with its oral area of sealing.Sebific duct 3 is enclosed within and can prevents on the needle tubing 1 that blood back and blood from spattering on support 4, test tube plug 5.If also need blood sample collection, needle tubing 1 need not be extracted, again a test tube 6 and a test tube plug 5 that sets quantitative negative pressure is pushed in the support 4, but the required blood volume of Automatic Extraction and flowing directly in the test tube 6 just.Extract needle tubing 1 after blood sample collection finishes, the test tube plug 5 that 6 one in test tube or a few Zhi Liantong is sealed in its oral area is sent to chemical examination in the lump.
Adopt the disposable use venous samples can harvester that this utility model proposed, when blood sample collection, directly enter in the test tube 6 by needle tubing 1 owing to blood sample, saved from disposable syringe and be transferred to this step of test tube, and the amount of blood sample collection is by negative pressure control in vitro, gatherer process is finished automatically, operates very easy; And the chemist can not adhere to blood sample, avoided pollution, and security reliability is good; Test tube 6 usefulness test tube plugs 5 sealings in this utility model, blood sample is not contaminated, is convenient to the transportation of blood sample test tube yet; Blood sample needn't shift once so hemocyte can be not damaged, check accuracy height.
