Abstract
The utility model relates to a medicine dispensing injection syringe capable of automatically exhausting the air, and belongs to the technical field of medical apparatuses and instruments, wherein the medicine dispensing injection syringe capable of automatically exhausting the air is simple in structure and low in cost. The medicine dispensing injection syringe capable of automatically exhausting the air eliminates the inconvenience of repeated pumping drainage of air of an existing injection syringe in a medicine dispensing process. The medicine dispensing injection syringe with an improved structure comprises a sleeve, a piston, a handheld handle, a papilla, a syringe needle seat, a medicating syringe needle, an exhausting syringe needle, an exhausting hole, an air filtering film, a liquid medicine in-out opening and an air in-out opening. The medicine dispensing injection syringe is characterized in that the medicating syringe needle and the exhausting syringe needle are arranged on the syringe needle seat, the medicating syringe needle and the exhausting syringe needle are both made of metal materials, the medicating syringe needle is used for medicating medicine, and the exhausting syringe needle is used for automatically exhausting air after the medicating so as to balance the pressure in an infusion bottle. The medicine dispensing injection syringe capable of automatically exhausting the air reduces exhausting and polluting opportunities, avoids the waste of the liquid medicine, rectifies negative pressure automatically, and is easy to operate and convenient and fast to use.
Description
Technical field
This utility model relates to a kind of medical syringe that makes up a prescription that uses when transfusion.
Background technology
Use syringe to make up a prescription to the venous transfusion needs of patients clinically, sometimes need to add the medicine of heavy dose of (30-100ml) in one bottle of liquid, traditional method is used is can not self-bleeding syringe, its inconvenient operation, need nursing staff's injection-bleed-the injection again-repeatable operation of bleeding again, increase labor intensity and opportunities for contamination, reduced work efficiency.
Summary of the invention
This utility model provides a kind of syringe that makes up a prescription of handled easily, and it is simple in structure, and is easy to operate.
A kind of Dispoable medical automatic vent syringe that makes up a prescription, comprise sleeve (1), piston (2), hand holding handle (3), nipple (4), needle holder (5), Medicated needle of syringe (6), aerofluxus syringe needle (7), steam vent (8), air filtration film (9), medicinal liquid gateway (10), air gateway (11), needle holder (5) goes up band Medicated needle of syringe (6) and aerofluxus syringe needle (7), Medicated needle of syringe (6), aerofluxus syringe needle (7) all adopts metal material to make, Medicated needle of syringe (6) adds medicinal, automatic vent after aerofluxus syringe needle (7) dosing is with balance infusion bottle internal pressure.
Described Medicated needle of syringe (6) leads to syringe nipple, and Medicated needle of syringe (6) does not communicate with aerofluxus syringe needle (7), and aerofluxus syringe needle (7) is than short 1 centimetre of Medicated needle of syringe (6).
Described aerofluxus syringe needle (7) bottom side mouth is established a steam vent (8), and vent ports is established one deck air filtration film (9), and the air filtration film adopts hydrophobic membrane to make.
This utility model has reduced aerofluxus, opportunities for contamination, has avoided liquid waste, and the automatic straightening negative pressure is simple to operate, convenient to use.
Description of drawings
Fig. 1 is the sectional structure chart of the syringe that provides of this utility model, among the figure 1, sleeve.2, piston.3, hand holding handle.4, nipple.5, needle holder.6, Medicated needle of syringe.7, aerofluxus syringe needle.8, steam vent.9, air filtration film.10, medicinal liquid gateway.11, air gateway.
The specific embodiment
At first syringe is inserted in the medicinal liquid bottle and extract medicinal liquid, medicinal liquid gateway (10) is under liquid level, air gateway (11) is on liquid level, medicinal liquid in the medicinal liquid bottle is entered in the syringe cylinder by the medicinal liquid gateway (10) of Medicated needle of syringe (6) at this moment, air then enters in the bottle by air gateway (11) from steam vent (8), to keep the air pressure unanimity inside and outside the medicinal liquid bottle.After finishing this operation, syringe be inserted in the liquid bottles, in liquid bottles, inject medicinal liquid, guarantee air gateway (11) in the liquid bottleneck, and more than liquid level, at this moment medicinal liquid is to come out from syringe, just opposite with the process of drawing liquid.
Claims (3)
