Description
Technical field
The utility model belongs to stem-cell therapy field, is related to stem-cell therapy equipment, especially a kind of to be suitable for doing carefully
The disposable syringe of born of the same parents' treatment.
Background technique
Currently in the clinical manipulation of biological therapy or cell therapy, the clinical use of cell preparation is with venoclysis drawn game
Based on portion's injection, the venoclysis operation of cell preparation is substantially conventional with reference to blood transfusion, using blood transfusion apparatus as delivery device, and cell system
The locally injecting of agent has no the past reference standard, also has without special syringe, is replaced substantially with ordinary syringe.
But cell preparation is injected using ordinary syringe, clinically there is certain irrationality and medical-risk,
In view of cell is easy to appear clustering phenomena in vitro, it is formed by cell mass and is easy blocking syringe needle, if cell mass
Once being injected into human body, then the risks such as local inflammation, allergic reaction even thrombus may occur.
Utility model content
It is a kind of suitable for stem-cell therapy the purpose of the utility model is to overcome providing in place of the deficiencies in the prior art
The technical issues of disposable syringe, effectively solution cell bolus injection, syringe is avoided to use cross-infection.
The utility model solves above-mentioned technical problem and adopts the following technical solutions to achieve:
A kind of disposable syringe suitable for stem-cell therapy, including needle tubing and piston, the piston coaxial are inserted into
In needle tubing, it is provided with graduation mark in needle wall, has integrally produced syringe needle in needle tubing front end, the needle tubing is divided into removably
It three sections, is from left to right followed successively by tip tube, middle section pipe and top pipe, the right side internal diameter of the tip tube and is coaxially arranged with the first rubber
Cushion rubber is coaxially arranged with the second rubber ring in the left end outer diameter of the middle section pipe, and the coaxial Demountable assembling of the first rubber ring is
In two rubber rings, it is coaxially arranged with third rubber ring in the right side internal diameter of the middle section pipe, in the left end outer diameter of the top pipe
It is coaxially arranged with the 4th rubber ring, the coaxial Demountable assembling of third rubber ring is in the 4th rubber ring, on the right side of the top pipe
The syringe needle has integrally been produced in side, is coaxially detachably equipped with filter in first rubber ring and third rubber ring,
Filter screen is offered with one heart on the filter.
Moreover, be coaxially arranged with the first cyclic annular clip outside the second rubber ring, the is coaxially arranged with outside the 4th rubber ring
Two cyclic annular clips.
It the advantages of the utility model and has the beneficial effect that
1, rubber ring is arranged in interface end, in the first rubber ring in traditional syringe subsection setup by the innovation of this syringe
With filter is detachably coaxially installed in third rubber ring, offer filter screen with one heart on the filter, can be according to need
The filter screen of different pore size is set, effectively solves the problems, such as that cell infusion is agglomerating, facilitates operation.
2, this syringe is coaxially arranged with the first cyclic annular clip outside the second rubber ring, is coaxially disposed outside the 4th rubber ring
There is the second cyclic annular clip, the leakproofness and stability for improving syringe is arranged in clip.
3, design is scientific and reasonable for the utility model, and structure is simple, and by subsection setup, traditional syringe is segmented, and
Filter is detachably installed in segmentation interface, effective filtration cell carries out secondary filter to cell, can be according to the needs of use
Setting, clinical tests prove that, aperture is that 30 microns of effect is good, such cell therapy special syringe is researched and developed, dedicated for
Biological therapy and cell therapy field are reduced cell therapy locally injecting risk, are suitable for specification cell therapy clinical manipulation
Large-scale popularization uses.
Detailed description of the invention
Fig. 1 is the main view of the utility model；
Fig. 2 is needle tubing assembling schematic diagram in Fig. 1；
Fig. 3 is filter structural schematic diagram in Fig. 1.
Specific embodiment
Below by specific embodiment, the utility model is described in further detail, following embodiment be it is descriptive, no
It is restrictive, protection scope of this utility model cannot be limited by this.
A kind of disposable syringe suitable for stem-cell therapy, as shown in Figure 1, including needle tubing and piston 1, the piston
It is coaxially inserted into needle tubing, graduation mark 4 is provided in needle wall, integrally produced syringe needle 7, the utility model in needle tubing front end
Innovative point be:
The needle tubing is divided into dismountable three sections, such as Fig. 2, is from left to right followed successively by tip tube 2, middle section pipe 5 and top
Pipe 6, the right side internal diameter of the tip tube are coaxially arranged with the first rubber ring 8, are coaxially disposed in the left end outer diameter of the middle section pipe
There is the second rubber ring 9, the coaxial Demountable assembling of the first rubber ring is same in the right side internal diameter of the middle section pipe in the second rubber ring
Axis is provided with third rubber ring 10, is coaxially arranged with the 4th rubber ring 11, third rubber ring in the left end outer diameter of the top pipe
Coaxial Demountable assembling has integrally produced the syringe needle on the right side of the top pipe in the 4th rubber ring.
Filter 13 is detachably coaxially installed in first rubber ring and third rubber ring, it is same on the filter
The heart offers filter screen 14, and the first cyclic annular clip 3 is coaxially arranged with outside the second rubber ring, is coaxially disposed outside the 4th rubber ring
There is the second cyclic annular clip 12.
Working principle of the utility model is:
In order to solve the technical issues of stem cell injection generates cell mass, disposable syringe in the prior art is arranged
