Description
Technical field
The utility model relates to a kind of tumor sampling devices, belong to the field of medical instrument technology.
Background technique
Currently, hospital needs to sample tumour cell mostly to the clinical examination of tumour, it is commonly exactly to push in syringe
Piston so that its is generated negative pressure, by the cell of affected area sucking syringe needle, but due to this body structure of human body, affected area may be deposited
In more body fluid, can preferentially suck body fluid when sucking histocyte, cause histocyte mix body fluid occur slip pipe or
The phenomenon that syringe inner body hypervolia causes cell soakage few, influences normal sampling work.
Utility model content
In order to overcome the above-mentioned problems in the prior art, the utility model provides a kind of tumor sampling device, the dress
When setting sampling histocyte and body fluid can separate, and when body fluid is more, can also be stored by secondary cylinder, into one
Step expands collection liquid space.
To achieve the goals above, the utility model adopts the technical scheme that a kind of tumor sampling device, including master
Cylinder and secondary cylinder, the secondary cylinder connection are connected with puncture needle in main cylinder front end, are arranged at intervals in main cylinder in the back segment of main cylinder
No.1 piston plate and No. two piston plates pass through spring between two pieces of piston plates and connect；It is provided with through-hole on the No.1 piston plate,
Filter membrane is provided in through-hole；No. two piston plates are also connected with No. two piston rods, are provided with No. three piston plates in the pair cylinder,
No. three piston plates are connected with No. three piston rods；The main cylinder leading portion corresponds to and is additionally provided with limited block, main cylinder on rear side of No.1 piston plate
Leading portion corresponds to and is connected with collecting chamber by connecting leg on front side of limited block, and valve is provided on connecting leg.
Further, No. two piston rods are connected with end cap.
Further, No. three piston rods are also connected with end cap.
Further, the main cylinder front end is provided with hemisphere face.
Further, corresponding No. two piston plates of the main cylinder back segment are also equipped with limited block.
Further, the connecting leg is greater than the thickness of No.1 piston plate at a distance from main cylinder connecting pin to limited block.
Due to the adoption of the above technical scheme, utility model has the advantages that the utility model is provided with two in main cylinder
Block piston plate, so that cylinder is formed two plunger shafts, the plunger shaft aspirates tissue cell of front side mixes body fluid, and the work of rear side
Body fluid is filtered by plug chamber using the strainer of first piston plate, to make histocyte concentrate on front side of first piston plate, most
It flows into collecting chamber eventually；And it when more in view of body fluid, can also be stored by secondary cylinder, further expand collection liquid air
Between.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Description of symbols: the main cylinder of 1-, 2- pair cylinder, 3- No.1 piston plate, No. bis- piston plates of 4-, No. bis- piston rods of 5-, 6-
No. three piston plates, No. tri- piston rods of 7-, 8- puncture needle, 9- collecting chamber, 10- limited block, 11- valve, 12- spring.
Specific embodiment
It is right with reference to the accompanying drawings and examples in order to keep the purpose of this utility model, technical solution and advantage clearer
The utility model is described in further detail.
The embodiments of the present invention: the structural schematic diagram of tumor sampling device is as shown in Figure 1, include main cylinder 1 and secondary cylinder
2, back segment of the secondary connection of cylinder 2 in main cylinder 1；It is machined with hemisphere face in main 1 front end of cylinder, puncture needle 8 is connected on hemisphere face；Main cylinder 1
It is inside arranged at intervals with No.1 piston plate 3 and No. two piston plates 4, is connected between two pieces of piston plates by spring 12；No.1 piston plate 3
On be machined with through-hole, through-hole is embedded with filter membrane, for separating body fluid and tissue cell；No. two piston plates 4 are also connected with No. two
Piston rod 5；No. three piston plates 6 are provided in secondary cylinder 2, No. three piston plates 6 are connected with No. three piston rods 7；Main 1 leading portion of cylinder corresponding one
3 rear side of number piston plate is also machined with limited block 10, and corresponding No. two piston plates 4 of main 1 back segment of cylinder are also machined with limited block 10；Main cylinder 1
Leading portion corresponds to and is connected with collecting chamber 9 by connecting leg on front side of limited block 10, and valve 11 is equipped on connecting leg, specifically, connecting leg and master
1 connecting pin of cylinder is greater than the thickness of No.1 piston plate 3 to the distance of limited block 10.No. two piston rods 5 and No. three piston rods 7 are connected with
End cap.
When the utility model is used, puncture outfit 8 is directed at affected area, No. two piston rods 5, No.1 piston plate 3, two are pulled
Shift-in row absorption in number piston plate 4, No.1 piston plate 3 is limited the limitation movement of block 10 later, and No. two piston plates 4 continue to move to,
Body fluid is filtered out by the filter membrane of No.1 piston plate 3；Since body fluid volume is more, No. three piston rods 7 are pulled at this time, expand collection
Liquid space.Final histocyte concentrates on 3 front side of first piston plate, and flows into collecting chamber 9.
