Device processed.
Background technique
Drug used for intravenous injection usually requires for a variety of stostes or pulvis to be used in mixed way, this just needs to be existed with syringe
It aspirates, inject repeatedly between different medical fluids and medicine bottle, the same injection needle is converted between different medical fluids using not only
Increase the labor intensity for the personnel that make up a prescription, a small amount of medical fluid being retained in hollow needle is also easy to cause secondary pollution, influences metering
Accurately.The compounding centers of hospital are frequently necessary to the drug that batch prepares the more same proportion of quantity, using one needle exchange of a medicine
It will cause a large amount of waste, replacement syringe needles also will increase the labor intensity for the personnel of making up a prescription for the mode of head.
Summary of the invention
Cross contamination simple, easy to use, without drug that the purpose of the utility model is to provide a kind of structures, syringe needle can weigh
The bulk drug dispenser used again.
Used technical solution is the utility model in order to solve the technical problem:
Bulk drug dispenser described in the utility model includes the pump installation that can be alternately produced positive/negative pressure, passes through pipeline
It is connected to the work package of pump installation output end, the work package includes pedestal, the sliding block being slidably connected with pedestal and consolidates
Surely the needle tubing being connected on pedestal is provided with installing blind on the pedestal, and the needle tubing is fixedly mounted on the installing blind
Axial location；The sliding block sliding sleeve is provided with spring, pacifies on sliding block with matching on needle tubing between sliding block and pedestal
Fill the plunger body of blind hole；Position on the side wall of the needle tubing, under plunger body covering has side opening, is provided in pedestal logical
Road, the inner end in the channel is connected to installing blind and the interior end opening in channel is corresponding with the position of the side opening, the column
The plunger side opening for being connected to side opening and channel is provided on the side wall of cock body.
Channel on the work package is connected to the output end of pump installation by threeway.
The pump installation is syringe.
Due to having adopted above structure, the bulk drug dispenser structure is simple, easy to use, is not necessarily to during making up a prescription in batches
Syringe needle is replaced, is conducive to the labor intensity for mitigating the personnel that make up a prescription, avoids the cross contamination of drug, improve the working efficiency to make up a prescription.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model one embodiment.
Fig. 2 is the enlarged structure schematic diagram of one of work package on state.
Specific embodiment
As shown in Figure 1, bulk drug dispenser described in the utility model includes the pump dress that can be alternately produced positive/negative pressure
It sets 1, be connected to the work package 2,3 of 1 output end of pump installation by pipeline.The pump installation 1 can using syringe or
The common injector syringe of person can also use electric reciprocating pump.When pump installation 1 generates negative pressure, pass through work package 2,3
Draw the medical fluid in medicine bottle；Pump installation 1 then injects the medical fluid of absorption in other containers when generating positive pressure.
The work package includes pedestal 4 and the sliding block 5 being slidably connected of pedestal 4 and the needle being fixedly connected on pedestal 4
Pipe 6, needle tubing 6 are the bevelled hollow pipes of front end band, are pricked in bottle inlet in order to puncture the lid of medicine bottle.It is set on the pedestal 4
It is equipped with installing blind 7, installing blind 7 is internal closed blind hole, and cross sectional shape can be circle and be also possible to regular polygon.
The needle tubing 6 is fixedly mounted on the axial location of the installing blind 7, and the inner wall that the rear end of needle tubing 6 is mounted blind hole 7 blocks,
Needle tubing 6 is set to become blind pipe；5 sliding sleeve of sliding block is provided with spring 52, in nothing on needle tubing 6 between sliding block 5 and pedestal 4
In the case where external force, spring 52 pushes sliding block 5 to leave 4 a distance of pedestal, and pressing sliding block 5 can then overcome spring 52
Active force is tightly attached to sliding block 5 on pedestal 4.The plunger body 51 of Matching installation blind hole 7 is had on sliding block 5, plunger body 51 is suit
Cylinder on needle tubing 6, cross sectional shape is consistent with the shape of installing blind 7 and the outer wall of its inner wall and needle tubing 6 slidably
The inner wall of ground tight fit, outer wall and installing blind 7 is slideably fitted close, and the height of plunger body 51 is less than installing blind 7
Depth, in order to allow plunger body 51 in installing blind 7 have certain axial movement space；The side of the needle tubing 6
Position on wall, under the covering of plunger body 51 has side opening 61, is provided with channel 41, the inner end in the channel 41 in pedestal 4
It is connected to installing blind 7 and the interior end opening in channel 41 is corresponding with the position of the side opening 61, the two is located at same level
On.The plunger side opening 53 for being connected to side opening 61 and channel 41 is provided on the side wall of the plunger body 51.As shown in Figure 1, working as
When sliding block 5 and plunger body 51 are located at bottom dead center position, plunger side opening 53 and the position of side opening 61 and channel 41 are staggered, side opening
61 and channel 41 blocked by plunger body 51；As shown in Fig. 2, when sliding block 5 and plunger body 51 move up, run to top dead centre position
When setting, side opening 61 and channel 41 are connected the aligned in position of plunger side opening 53 and side opening 61 and channel 41.
As the preferred embodiment of the present embodiment, using the identical work package of two structures, on the work package 2,3
Channel 41 is connected to the output end of pump installation 1 by threeway 8.Side in the case where no external force is intervened, in two work packages
Hole 61 and channel 41 are blocked by plunger body 51, and two work packages 2,3 are in a closed state.
In use, stoste medicine bottle is placed on the lower section of one of work package needle tubing 6, stoste medicine bottle is lifted and makes needle tubing 6
Needle point puncture bottle cap inject bottle body in, lift stoste medicine bottle bottle cap push sliding block 5 be up to top dead center position, at this time this
Side opening 61 and channel 41 in a work package are connected, and pump installation 1 generates negative pressure and stoste medicine can be drawn into pump barrel；Then
Stoste medicine bottle is removed, the sliding block 5 in this work package automatically resets, and side opening 61 and channel 41 are blocked by plunger body 51 again,
Another medicine bottle is placed on to the lower section of another work package needle tubing 6, using medicine bottle lid or manually to lift sliding block 5 i.e. openable
Side opening 61 and channel 41 in this work package, pump installation 1, which generates positive pressure, at this time to inject the medicine for the medical fluid in pump barrel
In bottle.As long as repeating aforesaid operations when preparing identical drug for the second time, it is dirty will not to generate intersection for no replacement is required syringe needle
Dye.
As the other embodiments of the utility model, pump installation 1 can also be led to by four-way or five connects more works
Make component, the drug for more dose components is prepared, and working principle is same as above.
