Description
Technical field
The present invention relates to a kind of medicine dispensation apparatus, specifically a kind of dispenser.
Background technology
Hospital nurse is when making up a prescription, it is common that make up a prescription by ordinary syringe, has work in the liquid suction pipe of ordinary syringe
Plug and the push rod being connected with piston, when making up a prescription, nurse needs repeatedly push-and-pull push rod to draw liquid, needs at work because of nurse to make up a prescription very
Repeatedly, thus at the end of the day nurse's push pull maneuver many times, the workload of nurse is very big, and in liquid suction pipe piston is below
Air can pollute liquid suction tube wall, and after piston post-tensioning sucks liquid, contaminated liquid suction tube wall is possible to pollute medicine
Liquid.Though ordinary syringe normal capacity is 20ml, but in real work, nurse is generally up to about drawing 10ml to 15ml liquid,
If because drawing 20ml, piston push rod major part is suspended on outside liquid suction pipe, and such push rod is very unstable, and nurse operation is stranded
Difficulty, therefore the knot of ordinary syringe is configured with the waste of middle syringe volume.
Content of the invention
It is an object of the invention to provide a kind of dispenser, big to solve amount of labour when nurse uses ordinary syringe to make up a prescription
Problem.
The present invention is achieved in that
A kind of dispenser, including shell body, liquid suction pipe, rotating seal and described rotating seal are just in fluid communication
Pressure pipe, negative tube and the microswitch installed on described fluid communication pipeline；Described liquid suction pipe, described rotatory sealing
Device and described microswitch are mounted in described outer shell, be provided with in described liquid suction pipe preceding piston and
After filter core；Position limiting structure is set between described liquid suction pipe and described shell body axially to limit described suction pipe
Position；Described microswitch is provided with air intake and connects with forward voltage diode, negative tube respectively, and described microswitch is used for being selectively opened
Forward voltage diode or negative tube；Described rotating seal includes dynamic portion and quiet portion, and described dynamic portion has the connection for described quiet portion cross-under
Cavity, and the front end in dynamic portion is plugged in the afterbody of described liquid suction pipe and arranges sealing gasket in junction；Described quiet portion is for opening
Having the cylinder of central airway, its front end is connected to the connection cavity in described dynamic portion and makes described central airway front end and described medicine
Liquid suction pipe aft fluid connects, and the joint in described dynamic portion and described quiet portion arranges sealing gasket, and in described quiet portion, move portion
The place of socket-connecting is provided with rotation connection structure, and the rear end of described central airway is in fluid communication with the gas outlet of described microswitch.
Preferably, the position limiting structure between described liquid suction pipe and described shell body includes at described liquid suction pipe tail
The locating piece of the outwardly convex that portion outer wall is arranged, the axial slideway sliding for locating piece arranging on described shell body inwall with
And the spacing draw-in groove along the circumferential direction of the end setting at described axial slideway.
Preferably, the connecting pipeline of described forward voltage diode and malleation source of the gas is disposed with barotropic gas pressure regulator,
Barotropic gas flow control valve.
Preferably, the connecting pipeline of described negative tube and negative pressure source of the gas is disposed with negative-pressure gas pressure regulator,
Negative-pressure gas flow control valve.
Preferably, described rotation connection structure is a bearing arrangement.
Preferably, described rotation connection structure is to offer cross bore in described dynamic portion, in described quiet portion with described
The position of cross bore phase docking has cambered surface groove, is provided with ball at this joint and is provided with sealing in described cross bore
Pad and spacing fixture can be carried out to ball.
Preferably, described liquid suction pipe volume is 10ml, 15ml or 20ml.
Preferably, the piston in the liquid suction pipe of described dispenser by the secondary piston being positioned above, be positioned at below after
The connecting rod of piston, connection secondary piston and back piston, the aseptic gas composition being sealed between secondary piston and back piston, secondary piston is shifted onto
Liquid suction pipe foremost when, the front end face of back piston milliliter number graduation mark maximum with on liquid suction pipe is concordant.
Described barotropic gas pressure regulator is provided with barotropic gas filtration core.
Described liquid suction pipe, described rotating seal and described microswitch are mounted on described shell by the present invention
It in body body, and between liquid suction pipe and shell body, is provided with axial limiting mechanism, thus avoid liquid suction pipe and shell body
Between produce and move axially, and then realize only pressing the convenience that the button on microswitch i.e. can control piston-advance or retrogressing
The target operating, thus, it is possible to real realization pushes a button to manipulate dispenser by manipulation, this pushes away by hand than in prior art
Pulling process bar controls suction liquid will easily much, therefore the present invention can significantly mitigate the amount of labour that nurse makes up a prescription.
In the present invention, the flow of barotropic gas flow control valve positive pressure adjustable gas, by regulating the stream of barotropic gas
The speed that amount adjusting piston moves forward；The pressure of negative-pressure gas pressure regulator adjustable negative pressure gas, negative-pressure gas stream
The flow of adjustable valve adjustable negative pressure gas, by regulating the speed that the flow adjusting piston of negative-pressure gas is moved rearwards by.
Due to liquid suction pipe and rotating seal move between portion, rotating seal moves portion and quiet portion joint all has sealing
Pave sealing function, therefore gas will not be revealed in rotating seal and liquid suction pipe.
Gas was carried out by the barotropic gas filter in the filter core in liquid suction pipe, barotropic gas pressure regulator
Filter, improves the cleanliness factor of liquid suction pipe piston gas below, reduces piston sky below compared with for ordinary syringe
The dustiness to liquid suction tube wall for the gas, after piston post-tensioning sucks liquid, liquid suction tube wall pollutes the possibility of liquid also
Decrease.
Due to the fact that by gas push-and-pull liquid suction pipe inner carrier, therefore will not produce with the absorption of push rod push-and-pull piston
Amount of liquid medicine makes unsettled the brought operation inconvenience of push rod major part close to piston during heap(ed) capacity near liquid suction pipe tail end,
Therefore the amount of liquid medicine using the present invention to draw easy can reach heap(ed) capacity, it is to avoid ordinary syringe uses 20ml specification
Liquid suction pipe and reality has only used the liquid suction pipe volume wasting phenomenon that 10ml to 15ml liquid suction pipe volume causes.
