Description
Technical field
The present invention relates to a kind of medical dispensation apparatus, specifically a kind of dispensers.
Background technology
Hospital nurse is typically made up a prescription with ordinary syringe when making up a prescription, and has work in the liquid suction pipe of ordinary syringe
Plug and the push rod being connected with piston, nurse need to push and pull push rod and draw liquid repeatedly when making up a prescription, because nurse needs to make up a prescription very at work
Repeatedly, so many times, the workload of nurse is very big for nurse's push pull maneuver at the end of the day, and piston is subsequent in liquid suction pipe
Air can pollute liquid suction tube wall, and after piston post-tensioning sucks liquid, contaminated liquid suction tube wall is possible to pollution medicine
Liquid.Though ordinary syringe normal capacity is 20ml, nurse, which is generally up to about, in real work can only draw 10ml to 15ml liquids,
Because piston push rod is largely suspended on outside liquid suction pipe if drawing 20ml, such push rod is very unstable, and nurse operation is tired
Difficulty, therefore the knot of ordinary syringe is configured with the waste of middle syringe volume.
Invention content
It is an object of the invention to provide a kind of dispensers, big to solve amount of labour when nurse is made up a prescription using ordinary syringe
The problem of, and can solve the problems, such as liquid medicine contamination
The invention is realized in this way：
A kind of dispenser, including outer housing, liquid suction pipe, rotating seal and the rotating seal are in fluid communication
Forward voltage diode, negative tube and the microswitch installed on the fluid communication pipeline；The liquid suction pipe, the rotation
Sealer and the microswitch are mounted in the outer shell, and preceding piston is equipped in the liquid suction pipe
With posterior filter core；It is axial to be carried out to the suction pipe that position limiting structure is arranged between the liquid suction pipe and the outer housing
Limit；The microswitch connects with forward voltage diode, negative tube respectively equipped with air intake, and the microswitch is for selectively beating
Open forward voltage diode or negative tube；The rotating seal includes dynamic portion and quiet portion, and the dynamic portion is provided with wears the company connect for the quiet portion
Cavity is connect, and the front end in dynamic portion is plugged in the tail portion of the liquid suction pipe and gasket is arranged in junction；The quiet portion is
Be provided with the cylinder of central airway, front end be connected to the connection cavity in the dynamic portion and make the central airway front end with it is described
Liquid suction pipe aft fluid is connected to, and is arranged gasket at the place of docking in the dynamic portion and the quiet portion, and in the quiet portion, move
The place of socket-connecting of portion is provided with rotation connection structure, and the rear end of the central airway and the gas outlet fluid of the microswitch connect
It is logical.
Preferably, the position limiting structure between the liquid suction pipe and the outer housing is included in the liquid suction pipe tail
The locating piece of the outwardly convex of portion outer wall setting, the axial slideway slided for locating piece being arranged on the outer housing inner wall with
And the limit card slot in the circumferential direction of the end setting in the axial slideway.
Preferably, be disposed on the connecting pipeline of the forward voltage diode and positive pressure air source barotropic gas pressure regulator,
Barotropic gas flow control valve.
Preferably, be disposed on the connecting pipeline of the negative tube and negative pressure air source negative-pressure gas pressure regulator,
Negative-pressure gas flow control valve.
Preferably, the rotation connection structure is a bearing arrangement.
Preferably, the rotation connection structure is to offer cross bore in the dynamic portion, in the quiet portion with it is described
The position that cross bore is connected to each other is provided with cambered surface groove, and ball is equipped at the docking and is equipped with sealing in the cross bore
Pad and can be to fixing piece that ball is limited.
Preferably, the liquid suction tube capacity product is 10ml, 15ml or 20ml.
Preferably, the piston in the liquid suction pipe of the dispenser by positioned at the secondary piston of front, be located at it is subsequent after
Piston, the connecting rod for connecting secondary piston and rear piston, the aseptic gas composition for being sealed in secondary piston and rear piston space, secondary piston are shifted onto
When the front end of liquid suction pipe, the front end face of rear piston is concordant with maximum ml graduation mark on liquid suction pipe.
Barotropic gas filtration core is equipped in the barotropic gas pressure regulator.
The liquid suction pipe, the rotating seal and the microswitch are mounted on the shell by the present invention
In body body, and axial limiting mechanism is equipped between liquid suction pipe and outer housing, to avoid liquid suction pipe and outer housing
Between generate axial movement, and then realize the convenience that need to only press the i.e. controllable piston forward or backward of button on microswitch
The target of operation pushes a button to manipulation dispenser thus, it is possible to really realize by manipulation, this is pushed away by hand than in the prior art
Pulling process bar come control 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 the stream for adjusting barotropic gas
Measure the speed that 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, the speed that the flow adjusting piston by adjusting negative-pressure gas moves backward.
There is sealing since liquid suction pipe and rotating seal move between portion, rotating seal moves portion and quiet portion joint
Sealing function is paved, therefore gas will not be revealed in rotating seal and liquid suction pipe.
The barotropic gas filter in filter core, barotropic gas pressure regulator in liquid suction pipe carried out gas
Filter, improves the cleanliness factor of the subsequent gas of liquid suction pipe piston, compared with reducing the subsequent sky of piston for ordinary syringe
Gas is to the dustiness of liquid suction tube wall, and after piston post-tensioning sucks liquid, liquid suction tube wall pollutes the possibility of liquid
It decreases.
The present invention not will produce due to pushing and pulling liquid suction pipe inner carrier by gas with push rod push-and-pull piston absorption
Liquid volume keeps push rod most of hanging caused inconvenient close to piston when maximum capacity close to liquid suction pipe tail end,
Therefore the liquid volume drawn using the present invention easy can reach maximum capacity, avoid ordinary syringe and use 20ml specifications
Liquid suction pipe and it is practical only used 10ml to be accumulated to 15ml liquid suction tube capacity caused by liquid suction tube capacity accumulate wasting phenomenon.
