Embodiment five
As shown in figure 5, being a kind of novel quantitative dispensing system structural schematic diagram of the utility model, the utility model is matched
Medicine system further includes medicine dissolving device.The handle is connect by power supply line and tracheae with gas source output device, and the medicine dissolving device is removable
That unloads is mounted on the handle.Clean air is delivered to the molten medicine by the handle by the gas source output device
Device, to drive the medicine dissolving device rubber plug to move, the filter in the handle to the air from the gas source output device again
Primary purification is carried out, to guarantee that inject the medicine dissolving device is the air of cleaning sterile.
The gas source output device is a body structure, inside upper box body and lower part box be divided by a thermal insulation layer,
Two opposing seal environment are formed, the thermal insulation layer has heat-insulated effect, prevents due to air pump, the equipment such as power supply produce when working
Raw amount of heat causes unnecessary damage to equipment.
The main pump is arranged in the lower part box, and the main pump adds the filter device of oil removing, water removal, to guarantee to set
Standby cleannes and high performance operation state.The upper box body is equipped with switch 15, for generating low current.The man-machine friendship
Mutual unit is arranged below the switch, is preferably provided at the 20-40mm of lower section.The main pump side is equipped with trigger device,
Receive the stimulation of the low current from the switch, generates high current, the on-off of the gas source output device circuit is controlled with this.
Usual electrical equipment is provided only with a button general pipeline as switch, presses as opening, but this simple switch will lead to
The operating current for flowing into equipment is larger, not safe enough.
In the present embodiment, the trigger device is relay, and after pressing the switch 15, the low current of generation stimulates institute
Relay is stated, so that its coil both ends is coupled with certain voltage, certain electric current is flowed through in coil, so that galvanomagnetic-effect is generated,
Armature will overcome spring effect to be drawn to iron core under the attraction of electromagnetic force, so that the movable contact with moving armature and stationary contact are inhaled
It closes, is turned on circuit；When closing, the switch, the coil blackout of the relay are first closed, the gravitation of electromagnetism also disappears therewith
It losing, the armature will return to original position under the reaction force of spring, and the movable contact and the stationary contact are discharged,
Circuit is disconnected.In this way by the suction and release between contact, to achieve the purpose that being switched on and off in circuit.It is described
The effect of the combination of switch and relay is: using Small current control high current, having one by the electric current of equipment in this way
Buffering, sharply will not become larger or become smaller, greatly ensure that the safety of equipment.
The thermal insulation layer is equipped with a medium effeciency filter, and air inlet extracts the lower part in the lower section of the thermal insulation layer
Through the rough filter filtered air in cabinet, and effectively remove the vapor that each equipment generates under higher temperature environment
And oil vapour, it avoids steam from being condensed into steam afterwards to the cold, influences the normal use of whole cleannes and equipment.It was imitated in described
Filter utilizes the inertia and diffusion of particle, and electrostatic interaction and chemical filtering effect filter the air, and structure is steady
It is fixed, there is preferable purification function.The air inlet of the main pump is extracted by the medium effeciency filter, the outlet of the main pump
It is located in the upper box body.
The intracorporal air of upper tank is to be extracted by the main pump by the medium effeciency filter, so relatively
Compare clean.Purification sub-device is equipped in the upper box body, compared with the main pump, the purification sub-device is flat for exporting
Surely, the small flow pure air mitigated, the main pump can be used as a kind of power source for exporting big flow pure air.
The lower end of the purification sub-device is the programmable logic controller (PLC) arranged side by side and the frequency conversion drive
Device.Furthermore it is possible to install sensor in each position of the gas source output device, system is judged by the data of the sensor
The working condition of system, it is easy to repair.The shell of the upper box body is equipped with small gas outlet, for arranging extra gas
Out, since the main pump constantly conveys gas to the upper box body, it will lead to air pressure inside raising, so the gas outlet
For equilibrium air pressure.The back housing of the upper box body is equipped with hook, can be used to hold the gas source output device, or will
It is suspended on wall equal places, provides convenience for the work of user.
The medicine dissolving device has syringe needle, cylinder and rubber plug, and the rubber plug is arranged in the inner barrel.Medicine dissolving device does not make
When the used time, i.e. initial position, the medicine dissolving device end and the rubber plug are maintained at same plane, and do not have dead angle, small to ensure
The medicine dissolving device end can be blown to sterile by power gas source with the rubber plug, and then guarantee the medicine dissolving device when in use,
Back cavity guarantees cleaning sterile.
After the medicine dissolving device is installed on the handle, start the work of making up a prescription of the dispensing system, comes from the gas
The power that the air of the main pump of source output device is moved as rubber plug in the medicine dissolving device.In practical operation, operator is hand-held
The handle, and by the related key and knob control operation on the handle, it is selected by the adjusting knob first
Then gear passes through the advance knob or output and the extraction sky for retreating knob and controlling the gas source output device
Gas.Air is after gas source output device output, via the filter in the handle and the handle, described in injection
Medicine dissolving device pushes the rubber plug to move ahead, the medical fluid in the medicine dissolving device is pushed out, and the rubber plug front end is clean nothing at this time
Bacterium air, rear end are also filtrated air；When press control key that the rubber plug retreats when, air is from the gas source output device
External sucking, enter the gas source output device via the high efficiency particulate air filter in the handle and the handle.At this point,
A negative pressuren zone is formed in the tail portion of the medicine dissolving device, the rubber plug is attracted to retract, the medical fluid in medicine bottle can be pumped into described
Medicine dissolving device.It is repeated several times in this way and controls the number that the rubber plug moves repeatedly using the forward key and Reverse keys, until
The quantitative fused completion of medical fluid.
The dispensing system sets the handle front end air by the gas source output device and the filter
The effect of changing can not only guarantee the quantification made up a prescription during entirely making up a prescription, and enable to the cavity of the medicine dissolving device
In remain gnotobasis, greatly guarantee use patient drug safety.
The utility model provides a kind of novel quantitative dispensing system, and the utility model is simple and reasonable, can not only
It realizes the quantification control during making up a prescription, and is capable of providing pure air, realize sterile dispensing, entire configuration process is fixed
It measures, is safe, sterile, reducing labor intensity, applicability is wide.
