Description
Technical field
A kind of medicine ordinance instrument is the utility model is related to, specifically a kind of closed drug configurator.
Background technology
During medicine ordinance, most cases are will to configure liquid either physiological saline and another powdered or liquid
Medicine mix.To avoid medicine exposure from being contaminated in atmosphere, and also to avoid volatile medicine from spreading,
The health of medical personnel is influenceed, this medicine ordinance needs the environment in sealing to carry out.In operation, first with syringe needle
Needle tubing suction configuration liquid or physiological saline, with the serum cap of punctures sealed vial, the liquid in needle tubing is injected into medicine bottle
In mixed with medicine, mixing complete after again with needle tubing extract out configure medicine use.It is close during injection configures liquid
Pressure caused by the medicine bottle of envelope can make needle tubing push away motionless, it is necessary to insert a hollow needle on bottle cap or puncture an aperture and subtract
Pressure, discharge the pressure in medicine bottle just can normally push configuration liquid later；Conversely, when the decoction configured is extracted, such as
The good sealing effect of fruit medicine bottle, the negative pressure in bottle prevent needle tubing aspiration medicinal liquid, it is also desirable to and acanthopore establishes respiration channel on bottle cap,
Balancing inside and outside pressure later just can normal operating.But puncture bottle cap or insert the method for hollow needle in the inside and outside pressure of balance
While power, the sealing in bottle is also destroyed, outside air, which can enter, pollutes decoction in bottle, the volatile medicine in bottle also can
By aperture to external diffusion, the health of medical personnel is endangered, rubber bottle cap is repeatedly punctured and is also easy to rubber grain being mixed into
In bottle, decoction is polluted, endangers the health of patient.
The content of the invention
The purpose of this utility model is to provide a kind of compact-sized, easy to use closed drug configurator, once wears
Thorn can complete the configuration of medicine, and configure whole closing, pollution-free, and no positive and negative pressure influences.
The utility model is that technical scheme is as follows used by solving technical problem：
Closed drug configurator described in the utility model includes decoction push pipe, the note installed in decoction push pipe front end
Syringe needle is penetrated, piston is slidably fitted with the decoction push pipe, the injection needle connects with the inner chamber of decoction push pipe, described
The front end of decoction push pipe is fixedly connected with breathing pipe mounting seat, and respiratory siphon is provided with the breathing pipe mounting seat, described to exhale
The front end of suction pipe is fixedly connected with respiratory siphon syringe needle, and the side of respiratory siphon is provided with Valve for aerocyst, and the respiratory siphon syringe needle is by exhaling
Suction pipe is connected with Valve for aerocyst, and air bag is provided with Valve for aerocyst.
The open rearward end of decoction push pipe, the front end of piston rod is fixedly connected on piston, rear end extends to push pipe
Outside is simultaneously fixedly connected with handle.
3-4 axially arranged fins are uniformly distributed on the excircle of the piston rod.
As a result of said structure, the medicine ordinance is compact-sized, easy to use, and one-time puncture can complete medicine
Configuration, and configures whole closing, no air pollution, medicine-less pollution, pollutes without rubber grain, not by the shadow of positive and negative pressure
Ring.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is Fig. 1 A portions local mode schematic diagram.
Fig. 3 is the overlooking the structure diagram of piston and piston rod.
Embodiment
1. as shown in figure 1, the utility model closed drug configurator includes decoction push pipe 1, pushed installed in decoction
The injection needle 2 of the front end of pipe 1, the decoction are pushed and piston 8 are slidably fitted with pipe 1, and the injection needle 2 is managed with decoction push
1 inner chamber connection, the front end of the decoction push pipe 1 are fixedly connected with breathing pipe mounting seat 3, and the breathing pipe mounting seat 3 is real
The cylindrical structure of core, described breathe is provided with respiratory siphon 4 in pipe mounting seat 3, as shown in Fig. 2 the rear end of the respiratory siphon 4 is set
The circular mounting groove being sleeved in breathing pipe mounting seat 3 is put, the front end of respiratory siphon 4 is fixedly connected with respiratory siphon syringe needle 5, respiratory siphon
4 side is provided with Valve for aerocyst 6, and the inside of respiratory siphon 4 is provided with passage, and the respiratory siphon syringe needle 5 passes through the passage on respiratory siphon 4
Connected with Valve for aerocyst 6, air bag 7 is installed on Valve for aerocyst 6.Above-mentioned injection needle 2 and respiratory siphon syringe needle 5 are needle point side openings
Syringe needle, can easily lunge the rubber bottle cap of medicine bottle.
In addition, the open rearward end of the decoction push pipe 1, the front end of piston rod 9 is fixedly connected on piston 8, rear end extension
It is fixedly connected to the outside of push pipe 1 and with handle 10, piston 8 can be promoted by handle 10 in decoction pushes pipe 1 to move back
It is dynamic.As shown in figure 3, being uniformly distributed 3-4 axially arranged fins 11 on the excircle of the piston rod 9, the fin 11 supports
Between the inwall of piston rod 9 and decoction push pipe 1, piston rod 9 can be made to be maintained at shaft core position, avoid piston 8 and piston
The skew of bar 9 causes piston seal not tight.
In use, first removing respiratory siphon 4 and respiratory siphon syringe needle 5 from decoction push pipe 1, now decoction pushes the front end of pipe 1
An only injection needle 2, extract configuration liquid or physiological saline using the injection needle 2 and pushed to decoction in pipe 1, then will
Respiratory siphon 4 and respiratory siphon syringe needle 5 are installed in breathing pipe mounting seat 3, and respiratory siphon syringe needle 5 and injection needle 2 are lunged into medicine simultaneously
On the rubber bottle cap of bottle, driving handle 10 and piston 8, decoction is pushed in the liquid injection medicine bottle in pipe 1, with the note of liquid
Entering, pressure increases in medicine bottle, and original portion gas can be entered in air bag 7 by respiratory siphon syringe needle 5 and respiratory siphon 4 in medicine bottle,
The volumetric expansion of air bag 7, reduce the pressure in bottle, so as not to cause too big resistance to piston 8, liquid all injects medicine bottle
In after, outside drawing handle 10 and piston 8, the decoction configured from injection needle 2 be withdrawn into decoction push pipe 1 in, now
Pressure in medicine bottle can reduce, and the gas in air bag 7 is withdrawn into medicine bottle again, the volume-diminished of air bag 7, in equalizing vial
Pressure, so as not to hinder the pulling motion of piston 8.
