Description
Technical field
The invention belongs to pathology department's technical field of medical instruments, it is related to a kind of pathology department's sample harvester.
Background technology
Pathology refers to the knot of the cell, tissue and organ of generation in the reason for disease occurs, nosogenesis and lysis
Change and its rule in terms of structure, function and metabolism.During clinical practice, some collections of specimens of pathology department often use syringe
Extract, such as spinal fluid, hydropericardium etc..And traditional syringe, if the negative pressure for extracting is too small, is taken out when Pathologic specimen is gathered
Pathologic specimen can not be taken, if negative pressure is excessive, after human body is punctured, being collected the Pathologic specimen for getting off can enter syringe to syringe
Interior, this result in sample and is not easily taken out again.And after puncture needle is extracted out, the negative pressure in syringe still can be by sample inspiration syringe
It is interior.It is existing that will air-vent be set on syringe, to open and close air-vent using plugging device, to discharge negative pressure, but discharge negative pressure
Operation and sampling operation are two independent operating procedures, therefore complex steps, and operating efficiency is low, and easily causes maloperation, because
This is necessary to be improved.
The content of the invention
The purpose of the present invention is directed to the above-mentioned problems in the prior art, there is provided one kind improves collection of specimens effect
Rate, it is to avoid in sample inspiration syringe, and easy to operate unified pathology department's sample harvester.
The purpose of the present invention can be realized by following technical proposal：A kind of pathology department's sample harvester, including syringe, pin

The adjusting set in grooving, adjusting set inwall and grooving bottom land palette are enclosed within, adjusting set length is less than grooving bottom land along syringe
The length of axis, adjusting set front end offsets with set front of the slot cell wall, and adjusting set is enclosed in ventilative outer end of hole, and can be towards after grooving
The mobile adjusting set in end, makes air-vent expose from adjusting set.
When using, puncture needle is penetrated in sample, pull shank, negative pressure is formed in syringe using piston, part is marked
In the pin hole of this inspiration puncture needle, and in operating process, one pulls dynamic shank, in order to keep syringe stabilization, another hand meeting
Adjusting set is promoted, adjusting set is enclosed in ventilative outer end of hole all the time, it is to avoid the negative pressure in influence syringe, extract puncture needle process out
In, direct pull adjusting set, and adjusting set can move towards grooving rear end, air-vent is exposed from adjusting set, to discharge pin
Negative pressure in cylinder, so as to avoid extracting out puncture needle moment, negative pressure in syringe is by the sample inspiration pin in the pin hole of puncture needle
Cylinder, causes sampling to fail, and this collector can make sampling operation and release negative-pressure operation combine together, easy to operate accurate.
In a kind of above-mentioned pathology department's sample harvester, grooving bottom land is provided with fluting shape bar shaped chute one and fluting shape arc
Shape chute two, chute two is coaxially disposed with syringe, and chute one is parallel with syringe axis, and the front end of chute one is close to syringe front end, and
It is connected with the front end of chute two, chute one and chute two form " L " shape structure, and adjusting set jacket wall is provided with perforation, adjusting set inwall
Sliding block is provided with, and when adjusting set front end offsets with set front of the slot, sliding block is located on chute two, and can be rotated around syringe axis
Adjusting set, makes sliding block move to the front end of chute two or rear end, and perforation is misplaced or is connected with air-vent, and is slided when sliding block is located at
During two front end of groove, also adjusting set can be moved towards back end of syringe, sliding block is moved on chute one, and make air-vent from adjusting set
Expose.
Therefore not only can open air-vent by pulling adjusting set, it is also possible to by rotary regulating sleeve, make perforation and
Air-vent is connected, therefore with various release negative pressure modes, can flexibly be used according to specifically used environment, and utilizes chute one
Coordinate with sliding block respectively with chute two, quickly can be adjusted between two kinds of occupation modes, it is to avoid two kinds of occupation modes occur
Intersect entanglement.
In a kind of above-mentioned pathology department's sample harvester, also including the compression spring being enclosed within grooving, and compression spring
Two ends offset with adjusting set rear end and grooving rear end cell wall respectively, and promote adjusting set front end to be against on set front of the slot cell wall.
Therefore compression spring is utilized, adjusting set returning quickly can be made, it is to avoid air-vent is opened for a long time after release of the negative pressure,
Cause maloperation.
In a kind of above-mentioned pathology department's sample harvester, described adjusting set is made up of transparent material.
Therefore it is easy to observation.
In a kind of above-mentioned pathology department's sample harvester, described adjusting set outer wall is provided with what is set around perforation outer end
Annular mark is raised.
Therefore doctor can also be facilitated carries out blind operation.
Compared with prior art, the invention has the advantages that：
When using, puncture needle is penetrated in sample, pull shank, negative pressure is formed in syringe using piston, part is marked
In the pin hole of this inspiration puncture needle, and in operating process, one pulls dynamic shank, in order to keep syringe stabilization, another hand meeting
Adjusting set is promoted, adjusting set is enclosed in ventilative outer end of hole all the time, it is to avoid the negative pressure in influence syringe, extract puncture needle process out
In, direct pull adjusting set, and adjusting set can move towards grooving rear end, air-vent is exposed from adjusting set, to discharge pin
Negative pressure in cylinder, so as to avoid extracting out puncture needle moment, negative pressure in syringe is by the sample inspiration pin in the pin hole of puncture needle
Cylinder, causes sampling to fail, and this collector can make sampling operation and release negative-pressure operation combine together, easy to operate accurate.
