Row discharge, is again extruded into bead 23 at the position of baffle ring 33, it is possible thereby to carry out extraction operation again.
When the solution inside drug storage pipe 1 is added to other containers or is injected into human body, pumping is removed at this time
Liquid syringe needle 13, on connector 14 install syringe needle 16, then it is middle when, bead is extruded into the hose 22 of 24 position of baffle ring
Then extraneous clip is installed in portion between bead 23 and hollow ball 21, then the forward promotion of piston boit 32, it is possible thereby to
So that the pressure inside drug storage pipe 1 increases, solution can be made to enter container from the position of syringe needle 16 or be injected into people
In body.
The present invention is inserted into drawing liquid syringe needle the inside of solution storage structure when carrying out the extraction of medical fluid, and liquid pumping needle
The top of head is enclosed construction, and solution enters from the import of side, and the rubber stopper that thus can not only prevent closing from using enters
To the inside of drawing liquid syringe needle, it is possible thereby to which the rubber stopper particle for effectively preventing closing from using enters in solution.Pass through piston
Pipe is extracted, and is thus extracted to the air inside drug storage pipe, so that the pressure inside drug storage pipe reduces, is thus made
The solution for obtaining solution storage inside configuration can smoothly enter the inside of drug storage pipe, while the separation of piston tube and drug storage pipe
Formula setting, can effectively avoid the particulate matter on piston head from entering in solution.Drug storage pipe owns before being not used
Opening pass through closing cap and closed, thus, it is possible to effectively prevent extraneous dust or sundries from entering closing cap storage
The inside of pencil ensure that the spatter property inside drug storage pipe, and the separate type of drug storage pipe and piston tube is arranged, so that medical fluid will not
The inside for entering drug storage pipe, the use that piston tube is repeated reduce the cost used.The structure of connector is set
It sets, user is changed according to position of the demand used to bead, it is possible thereby to realize connector, piston tube
Different connected relations, easy to operate between drug storage chamber, is easy to use.
