Description
Technical field
The utility model belongs to sample devices field, especially a kind of clinical blood sampler.
Background technique
Blood test is most basic one of detection means, is referred to through blood analysis inspection, determines that human body anaemia, gallbladder are solid
The inspection of situations such as alcohol, diabetes, various infection, renal function, calcium, liver function, abnormal hematologic disease and body.It is hospital most
One of common chemical examination content.Blood test should be specified by doctor's advice, and doctor is clear using inspection result or supports diagnosis, supervision or
It determines treatment means, and screening is made to the undetermined state of an illness.
Blood sampling is carried out to patient currently, disposable syringe is usually used, blood is transferred to guarantor after sampling
Container is deposited, during transfer, blood is easy to contact with air, due to oxygen, carbon dioxide equal size and the sky in blood
Gas is inconsistent, and blood constituent is caused to change, and causes testing result not accurate enough.
Utility model content
The purpose of this utility model is to provide a kind of clinical blood samplers, inject blood while sampling and save
Container prevents contacting blood air and leads to the changes of contents of the ingredients such as oxygen, carbon dioxide, guarantees the accurate of blood test
Property.
Purpose of the utility model is realized as follows: a kind of clinical blood sampler, including injector cartridge, the note
One end of emitter cylinder is provided with syringe needle, is internally provided with piston, and the piston is connected with push rod,
The syringe needle is connected by the first check valve with injector cartridge, and the conducting direction of first check valve is by needle
Head leads to inside injector cartridge, and the injector cartridge is provided with dismountable second one-way valve, institute close to one end of syringe needle
The conducting direction for stating second one-way valve is by leading to outside injector cartridge inside injector cartridge；The second one-way valve connection
There is dismountable storage cylinder, the storage cylinder is provided with bottom plate far from one end of second one-way valve, is arranged on the bottom plate
There is venthole, the storage cylinder is internally provided with sliding block, and the inner wall of the sliding block and storage cylinder slidingly and sealingly cooperates.
Further, the second one-way valve is connected by screw thread with injector cartridge.
Further, the second one-way valve is connected by screw thread with storage cylinder.
It is stored the beneficial effects of the utility model are: this blood sampler can inject blood while extracting blood
Cylinder, anti-Hemostatic Oral Liquid are contacted with extraneous air, guarantee and cause the changes of contents of the ingredients such as oxygen, carbon dioxide, guarantee blood
The accuracy of fluid inspection.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of clinical blood sampler of the utility model, including injector cartridge 1, the syringe cylinder
One end of body 1 is provided with syringe needle 2, is internally provided with piston 3, and the piston 3 is connected with push rod 4,
The syringe needle 2 is connected by the first check valve 5 with injector cartridge 1, and the conducting direction of first check valve 5 is
Led to inside injector cartridge 1 by syringe needle 2, the injector cartridge 1 is provided with dismountable second list close to one end of syringe needle 2
To valve 6, the conducting direction of the second one-way valve 6 is by leading to outside injector cartridge 1 inside injector cartridge 1；Described
Two check valves 6 are connected with dismountable storage cylinder 7, and the storage cylinder 7 is provided with bottom plate far from one end of second one-way valve 6
8, venthole 9 is provided on the bottom plate 8, the storage cylinder 7 is internally provided with sliding block 10, the sliding block 10 and storage barrel
The inner wall of body 7 slidingly and sealingly cooperates.
Injector cartridge 1, piston 3, push rod 4 and syringe needle 2 carry out on the basis of existing common blood uses syringe
It improves, increases the first check valve 5 and second one-way valve 6.First check valve 5 and second one-way valve 6 are using existing conventional
Check valve.Plastic cylinder or stainless steel cylinder can be used for storing blood pressure in storage cylinder 7.The initial bit of sliding block 10
7 inside of storage cylinder is set to close to one end of second one-way valve 6, air is avoided to be mixed into blood sample.
The use process of this blood sampler are as follows: vascular puncture is carried out to patient using syringe needle 2, push rod 4 is pulled, by blood vessel
In blood be pumped into injector cartridge 1 in, then push push rod 4, by injector cartridge 1 blood injection storage cylinder 7, with
The injection of blood, sliding block 10 by blood thrust and towards the direction of bottom plate 8 slide.Due to the first check valve 5 and second
The presence of check valve 6 ensure that blood is able to enter injector cartridge 1 in blood drawing, and when blood is injected storage cylinder 7,
Blood is merely able to enter storage cylinder 7, and cannot be discharged from syringe needle 2.After the completion of sampling, by second one-way valve 6 from syringe cylinder
It is removed on body 1；When detecting blood, second one-way valve 6 is removed from storage cylinder 7, blood sample can be extracted and examined
It surveys.
In order to rapidly dismount second one-way valve 6, the second one-way valve 6 is connected by screw thread with injector cartridge 1.Institute
It states second one-way valve 6 and is connected by screw thread with storage cylinder 7.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
