Fig. 1-5 is please referred to, the utility model provides a kind of technical solution:
Disposable sterilized syringe, as shown in Figure 1, include syringe 1, syringe 1 be equipped with plunger 2, the one of syringe 1
End is equipped with needle section 3.
In the present embodiment, it is plastic material, it can be achieved that when drug enters not by drug corruption that syringe 1 and plunger 2, which use,
The effect of erosion.
As Figure 2-3, syringe 1 includes inner needle tube 10, and one end of inner needle tube 10 has closely bonded connection tube 101, interior needle
The surface of pipe 10 is equipped with screw thread, and the first notch 102 is offered on the screw thread on 10 surface of inner needle tube, tight at the port of inner needle tube 10
It is close to be bonded with position-arresting disk 103, a pair of second notch 1031 is offered on position-arresting disk 103, and strainer 104 is installed in position-arresting disk 103,
The external screw-thread of inner needle tube 10 is connected with outer needle tubing 11, and the end of outer needle tubing 11 has closely bonded pulling plate 111.
In the present embodiment, it is coated with graduation mark in the first notch 102, and inner needle tube 10 is using transparent plastics material,
When to realize that drug is inner into interior syringe 10, the effect of drug capacity is observed.
In the present embodiment, positional symmetry between two the second notches 1031, and it is viscous on 1031 mouthfuls of walls of each second notch
It is connected to diaphragm seal, so that the effect for promoting leakproofness between connecting rod 22 and the second notch 1031 can be realized.
Further, for strainer 104 using HEPA filter screen, HEPA filter screen is a kind of high efficiency particle air filter,
The characteristics of filter effect reaches HEPA standard, reaches 99.7%, HEPA net for the effective percentage of 0.1 micron and 0.3 micron is empty
Gas can pass through, but tiny particle can not be by, it can be achieved that the most effective filtering of the pollutants such as smog, dust and bacterium
Effect, so that the effect for carrying out isolation air plankton inside internal needle tubing 10 can be realized.
In the present embodiment, each connecting rod 22 runs through the second notch 1031, and the size of the two is mutually adapted, so as to reality
When now pushing push plate 23, the effect for driving injection plug 24 to squeeze into syringe 1 by two connecting rods 22 avoids traditional column core 21
There is a situation where that gap allows bacterium to enter in syringe and occurs between syringe 1.
As shown in figure 4, plunger 2 includes column core 21, it is closely bonded with a pair of of nose bar 211 on column core 21, it is close on column core 21
For bonding there are two connecting rod 22, the side of column core 21 has closely bonded push plate 23, and the other side of column core 21 is equipped with injection plug 24, injection
It is closely bonded between plug 24 and each connecting rod 22.
In the present embodiment, positional symmetry between two nose bars 211, and each nose bar 211 is in outer 11 active procedure of needle tubing
In limit blocking is carried out to it, thus when the port for rotating outer needle tubing 11 to outer needle tubing 11 is aligned with target scale, also simultaneously
It pushes two nose bars 211 to corresponding position, has accordingly extracted quantitative drug in inner needle tube 10 at this time, realized accurate control medicine
Object extracts the effect of capacity, avoids traditional medical staff and pulls out extraction drug outside and cause drug to extract excessive situation and occur.
As shown in figure 5, needle section 3 includes adapter 31, adapter 31 is in open column shape, and on the inside and outside wall of adapter 31
It is equipped with screw thread, is threadedly coupled between adapter 31 and connection tube 101, offers through-hole 311 on adapter 31, in through-hole 311

In the present embodiment, the length of syringe needle cover 33 is greater than the sum of the length of adapter 31 and syringe needle 32, so as to avoid working as
The inconsistent situation in the top of syringe needle cover 33 and syringe needle 32 occurs.
The disposable sterilized syringe of the present embodiment when in use, rotates syringe needle cover 33 first and extracts syringe needle cover
33, then syringe needle 32 is placed in and is extracted in medical fluid, outer needle tubing 11 is rotated at this time, due to screw thread between outer needle tubing 11 and inner needle tube 10
Connection, with the rotation of outer needle tubing 11, outer needle tubing 11 moves outward, and the quarter on the move constantly exposed on inner needle tube 10
Degree, in addition while outer needle tubing 11 is mobile, outer needle tubing 11 constantly pushes nose bar 211, so as to drive column core 21 to be displaced outwardly,
Final injection plug 24 also moves in inner needle tube 10 therewith, so as to which medical fluid to be drawn into inner needle tube 10, and extracts medical fluid
Capacity can be with accurately controlling extraction amount after the outer needle tubing 11 that stops operating；
Before and after the syringe use, due to going out to be equipped on strainer 104 and plunger 2 in the nozzle of inner needle tube 10
Connecting rod 22 runs through the second notch 1031, to can realize to the effect for carrying out isolation impurity entrance inside the syringe.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Be only the utility model preference, be not intended to limit the utility model, do not departing from the spirit and scope of the utility model
Under the premise of, the utility model also has various changes and improvements, these changes and improvements both fall within claimed it is practical
In novel range.The protection scope of the present invention is defined by the appended claims and their equivalents.
