Description
Technical field
This utility model relates to a kind of medical apparatus, a kind of double-jacket tube arterial blood drawing syringe.
Background technology
Blood gas analysis needs to gather arterial blood gas specimen, is clinical common nursing manipulative skill.Along with sending out of high quality nursing
Exhibition, preset type arteria hemostix is because having more advantage compared with ordinary syringe, extensive in clinical practice, but following
Inconvenience is still had: 1. when needle of retaining on artery leaves and takes vim and vigour specimen in the case of two kinds；In order to ensure the standard of arterial blood gas analysis
Really property, generally requires and is first evacuated in syringe by the blood of remaining needle leading portion, then with heparin sodium diluent moistened tube chamber or
Use preset type arteria hemostix instead and carry out leaving and taking of arterial blood gas, easily occur caused by blood outflow when changing syringe
Pollute, too increase the chance that remaining needle infects；2., during the diagnosis and treatment of patient, generally require and check arterial blood simultaneously
Edema caused by disorder of QI analysis and other routine test project (such as electrolyte), when twitching arteries and veins blood gas analysis specimen, syringe needs heparin sodium dilute
Release liquid to moisten containing anticoagulant cotton piece in tube chamber or tube chamber, and the chemical examination of other routines such as electrolyte requires that tube chamber must not contain
Anything, otherwise will affect result of laboratory test, and therefore, syringe changed in puncture by clinical needs, even carries out two
Secondary puncture, and during changing syringe, the caused pollution of blood extravasation, syringe needle displacement and nurse's acupuncture easily occur
The phenomenons such as wound.
Summary of the invention
This utility model is directed to a kind of double-jacket tube arterial blood drawing syringe, it is not necessary to change syringe, can be the completeest
Become artery blood gas sample collection operation.
This double-jacket tube arterial blood drawing syringe includes outer syringe and inner injector, and outer syringe is by outer syringe, outer push rod
Being formed with outer piston, inner injector is made up of interior syringe, inner push-rod and inner carrier.After the nipple of outer syringe front end
There are one section of lengthening, internal diameter increasing portion in portion, and outer push rod becomes cylindrical shape, the front end face of outer push rod to fix with outer piston, extrapolation
Each circular hole is had on the front end face of bar and outer piston；Inner injector inserts in outer push rod, outside the anterior insertion of inner injector
In circular hole on the front end face of push rod and outer piston；The nipple of interior syringe front end insert the nipple rear portion of outer syringe lengthening,
In internal diameter increasing portion.
This double-jacket tube arterial blood drawing syringe can rely on the blood sample of outer syringe and inner injector two parts of different purposes of extraction,
It is changed without syringe and can complete the acquisition operations of arterial blood gas specimen.

Detailed description of the invention
As it is shown in figure 1, this double-jacket tube arterial blood drawing syringe includes outer syringe 1 and inner injector 2.Outer syringe 1
Being made up of outer syringe 11, outer push rod 12 and outer piston 15, outer piston is fixed on the front end of outer push rod, and outer piston is with outer
The anterior of push rod inserts in outer syringe 11.As shown in Figure 4, inner injector 2 is by interior syringe 21, inner push-rod 22 and interior work
Plug 24 is formed.Inner carrier is fixed on the anterior of the front end of inner push-rod, inner carrier and inner push-rod and inserts in interior syringe 21.
As in figure 2 it is shown, there are one section of lengthening, internal diameter increasing portion 14 in the rear portion of the nipple 13 of outer syringe 11 front end, as it is shown on figure 3,
Outer push rod 12 becomes cylindrical shape, the front end face of outer push rod 12 to fix with outer piston 15, the front end face of outer push rod 12 and outer
Having each circular hole 16,17 on piston 15, these two circular holes are aligned with each other.As it is shown in figure 1, outside inner injector 2 inserts
In push rod 12, in the circular hole 16,17 on the anterior front end face inserting outer push rod 12 of inner injector 2 and outer piston 15；
The nipple 23 of interior syringe 21 front end inserts in the lengthening at rear portion of nipple 13 of outer syringe 11, internal diameter increasing portion 14.
When gathering arterial blood gas specimen with this double-jacket tube arterial blood drawing syringe, as it is shown in figure 5, outer push rod 12 and outer work
Plug 15 pulls back (owing to the front end face of interior syringe 21 withstands outer syringe 11 relative to inner injector 2 and outer syringe 11
The inwall of front end face, actually only need to pull back outer push rod 12 relative to inner injector 2), by the blood of remaining needle leading portion
In the outer syringe 11 of suction, blood is that the space between the nipple 13 by outer syringe and the nipple 23 of interior syringe enters outer pin
In cylinder 11；As shown in Figure 6, then inner push-rod 22 and inner carrier 24 are pulled back, by syringe in arterial blood gas suction
In 21, then the blood sample in interior syringe and outer syringe is injected separately in different test tubes, only needs a secondary syringe, once wear
Thorn, can complete operation of all taking a blood sample.In operating process, the sealing between outer piston 15 and interior syringe 21 relies on outer living
The elasticity of the inwall of the circular hole 16 on plug 15 realizes.
When extracting arterial blood gas analysis and other routine test blood sample with this double-jacket tube arterial blood drawing syringe simultaneously, can
First extract routine test blood sample with outer syringe 11, then extract blood gas analysis blood sample with interior syringe 21, then it is noted respectively
Enter in different test tubes.
Structure shown in Fig. 1, the nipple 13 of outer syringe 11 front end is positioned at the center of syringe, the structure shown in Fig. 7, outward
The nipple 13 of syringe 11 front end is partial to the side of syringe, circular hole 16 on the front end face of outer push rod 12 and outer piston 15,
17 sides that the most just need to be partial to syringe.
The tube chamber of the interior syringe 21 in this double-jacket tube arterial blood drawing syringe can be equipped with anticoagulant cotton piece.This double-jacket tube
Inner injector 2 in arterial blood drawing syringe can also use BD preset type arteria hemostix.
