Described syringe 1 is cylinder.
During use, the middle finger of the right hand and forefinger can be inserted in finger ring A respectively, while insert a thumb into finger ring B,
When needing liquid to be extracted from air-tight bottle, first needle body is pierced in air-tight bottle, make the thumb in finger ring B drive tail cap, piston handle
Slided to the right side of injection tube with piston block in the lump, made in negative pressure state in injection tube, now, the liquid in air-tight bottle will pass through
Inlet opening, and entered in injection tube using liquid suction pipe and connecting tube, after negative pressure is formed in air-tight bottle, one-way valve A will be opened
Open, the air outside air-tight bottle will enter to air-tight bottle through filter cartridge, extending head and air inlet pipe from air admission hole by open-work B
Interior, after the negative pressure in bottle to be sealed is alleviated, one-way valve A is closed, and one-way valve A can prevent the liquid in air-tight bottle from utilizing air inlet
Overflow in Guan Bingcong open-work B, open-work A passes through activated carbon block, filter dirt cotton to may filter that the less dust of particle in air beneficial to air,
Activated carbon block can absorb the poisonous and harmful substance in air, and the dirt being prevented effectively from air is entered in air-tight bottle, is prevented
Sterile liquid medicine in air-tight bottle is contaminated, and when dissolved solid medicine is needed, first closes switch valve, makes liquid suction pipe and connecting tube
Between path cut-out, then screwed plug is back-outed from threaded walls A, by note that is getting ready in advance and pumping solid drugs and solution
Emitter is connected with side pipe by threaded walls A, then by solid drugs and solution by side pipe and connecting tube be rapidly injected in the lump to
In injection tube, again the solid drugs in injection tube are quickly refunded to the syringe being connected with side pipe, so with solution afterwards
Operate 4 to 5 times repeatedly, the torrent and whirlpool that solution is produced when flowing can be fully immersed into solid drugs to solution, the method
It is not only time saving and energy saving, can also effectively prevent solid drugs and solution from contacting and caused pollution with extraneous dirt, when take out medicine with it is molten
Switch valve after hours, is adjusted to closed mode by medicine, then screwed plug is screwed back completes the envelope to side pipe into threaded walls A
It is stifled, make in sealing state in injection tube, to ensure that the liquid in injection tube is not polluted by extraneous dirt, when needs will note
When liquid in shooting cylinder is injected in infusion bag, first tail cap is backed out from threaded walls D, tail cap is separated with piston handle, now,
The tip of interior needle body right-hand member is extracted from rubber stopper with fluid hole, makes fluid hole in opening state, and operator can be with the right side afterwards
Holding is in one's hands on pad, using the rubber stopper of infusion bag bottom, the tip of interior needle body right-hand member and fluid hole is pierced into infusion bag in the lump
It is interior, the rubber stopper of infusion bag bottom is propped up the tip of interior needle body right-hand member and the right-hand member of piston handle afterwards, will be living using piston handle
Chock is promoted to the left side of injection tube, makes to form barotropic state in injection tube, and now one-way valve B is unlocked, in injection tube
Liquid can be entered in infusion bag by interior needle body and from fluid hole, and interior needle body is had not been used before this, so ensure that
The germ-free condition of interior needle body, so as to greatly reduce the contaminated probability of sterile solution in infusion bag, unidirectional film B can avoid outer
The dirt on boundary enters to cause in injection tube environment in injection tube to be contaminated by interior needle body adverse current, when interior needle body right-hand member tip with
When fluid hole is pierced in infusion bag in the lump, the process of whole injection keeps the tip of interior needle body right-hand member and the rubber of infusion bag bottom
Plug is in the state that offsets, it is to avoid during injection, the possibility that the tip of interior needle body right-hand member is deviate from from infusion bag, so as to
The seal of injection tube and infusion bag is greatly reinforced, the contaminated probability of infusion bag inner liquid medicine has been greatly reduced, tab bar has been used
The title of medicine in the mark injection tube, dosage and time of compounding check work so as to operator.
The utility model simple structure, it is vdiverse in function, can not only avoid that negative pressure is excessive in air-tight bottle, make the mistake of extraction liquid
Cheng Gengjia is facilitated, while the dirt in can preventing air-tight bottle extraneous air is entered in air-tight bottle, reduces sealing to greatest extent
The bottle contaminated probability of inner liquid medicine, can dissolve solid-state drug without the need for acutely shake, it is to avoid air-tight bottle be shattered or liquid from
The possibility overflowed in air-tight bottle, is the molten medicine of nurse, makes up a prescription.
