The disposable closed type medicine adding device is composed of a liquid filling pipeline and an air filling pipeline, wherein the liquid filling pipeline is connected by an inner cavity of a long needle tube, a liquid filling pipeline in a seat of the long needle tube, a liquid filling leather tube, a liquid filling pipeline in a seat of a short needle tube and an inner cavity of the short needle tube. The air filling pipeline is divided into a long air filling pipeline and a short air filling pipeline; the long air filling pipeline is connected by a trepan boring of the long needle tube, a gap outside the long needle tube, an air filling pipeline in the seat of the long needle tube, an air filling leather tube and a long air filling seat port in the seat of the short needle tube; the short air filling pipeline is mutually connected by a trepan boring of the short needle tube, a gap outside the short needle tube in the seat of the short needle tube, an air filling pipeline in the seat of the short needle tube and a soft bag connected with the air filling pipeline. The long needle tube and the short needle tube are side boring needles; a filter membrane is arranged in the long air filling seat port. The disposable closed type medicine adding device solves the problem that the traditional medicine adding device can not effectively dispense medicines by controlling the ingress and egress of air in the pipeline. The utility model is applied in clinic.

Description

The closed drug feeding device of disposable use

Technical field this utility model relates to a kind of chemicals dosing plant, belongs to medical medical apparatus and instruments.

Background technology for a long time, the dosing apparatus of Shi Yonging is made up of syringe needle, syringe clinically, the medical worker arrests syringe with hands during use, and needle point is inserted medicine bottle aerating in airtight medicine bottle, drawing liquid, like this, the syringe needle syringe needs repeatedly dealing to use.Medical worker's hands contacts nook closing member easily, easily pollutes medicinal liquid, and when taking out medicine, resistance is big, inconvenient operation, and medicinal liquid is also easily residual, outer to drip.

The summary of the invention the purpose of this utility model just provides that a kind of pollution is few, and drug waste is few, the easy to operate closed drug feeding device of disposable use.

Technical scheme this utility model is made up of fluid-through tube road and long airway, the fluid-through tube road is by the minute hand pipe, fluid-through tube road in the minute hand seat, logical liquid leather strap, fluid-through tube road in the hour hand seat, the hour hand pipe is connected in sequence, airway divides long airway and short airway, long airway is by the needle tubing trepanning, minute hand pipe external series gap, breather line in the minute hand seat, the ventilation leather hose, long ventilation seat mouth on the hour hand seat is connected in sequence, short airway is by the hour hand canister aperture, hour hand pipe external series gap in the hour hand seat, breather line and connected soft bag interconnect and form in the hour hand seat, minute hand pipe and hour hand pipe are the side opening pin, in the long ventilation seat mouth filter membrane is arranged, during use, with long airway the gas in the infusion bottle is extracted out, medicinal liquid can enter in the infusion bottle by the fluid-through tube road.Fluid-through tube road tube wall is smooth airtight, and when medicinal liquid passed through, less wastage polluted and lacks, and its operation does not need dealing medicinal stripe insertion bottle, can be controlled by electrification, and is easy to operate.Beneficial effect is compared with traditional dosing apparatus, and it replaces original loosely organized syringe needle syringe with fluid-through tube road, breather line, makes it to pollute and lacks, and liquid waste is few, and is easy to operate.

The structure chart of description of drawings Fig. 1 product

Among the figure: 1, the interior fluid-through tube road 15. of breather line 14. hour hand bases leads to the liquid leather hoses in minute hand pipe 2, minute hand canister aperture 3, minute hand pipe external series gap 4, the interior breather line 5 of minute hand base, the interior fluid-through tube road 6 of minute hand base, the ventilation skin official 7. a long mouth 8. filter membranes 9. soft bag 10. hour hand canister apertures 11. hour hand pipes 12. hour hand pipe external series gaps 13. hour hand bases of ventilating

Specific embodiment this utility model is made up of minute hand pipe 1, minute hand seat, logical liquid leather hose 15, ventilation leather hose 6, hour hand seat, hour hand pipe 11 and soft bag 9.Minute hand pipe 1 front end has a side opening, thrust rubber stopper and do not produce exfoliation, its end is inserted in the minute hand seat, fluid-through tube road 5 in the elongated needle stand of inner chamber, minute hand seat one end is the minute hand pipe box, on minute hand canister aperture 2 is arranged, the other end has two outstanding logical liquid leather hose 15 and the ventilation leather hoses 6 of connecting respectively, annular minute hand pipe external series gap 3 is arranged between minute hand pipe box and the minute hand pipe, minute hand pipe external series gap 3 rings are trapped among outside the minute hand pipe 1, and the space is little, and opening is a minute hand canister aperture 2, in breather line 4 in the elongated needle tubing seat, and gas skin tube 6 all again.The other end of logical liquid leather hose 15 is connected on the hour hand base, ventilation leather hose 6 is by long ventilation seat mouthful 7 pass-outs on the hour hand base, long ventilation seat mouthful 7 sides of giving prominence at the hour hand base, the gas tube orifice of shape and air pump is supporting, air pump is realized electrified operation by this mouth, logical liquid leather hose 15 passes through the interior fluid-through tube road 14 of hour hand base by hour hand pipe 11 inner chamber pass-outs, there is an annular gap 12 hour hand pipe outside, its opening is a hour hand canister aperture 10, breather line 13 in the interior logical hour hand base, soft bag 9 of short ventilation road junction connection, supplied gas and the medicinal liquid turnover and the storage of overfilling and have filter membrane 8 in the long ventilation seat mouth 7.

Soft bag 9 in the hour hand base, short blow vent, breather line 13, hour hand pipe external series gap 12 interconnect with hour hand canister aperture 10 forms short airway.

Breather line 4, outer gap 3, the minute hand canister aperture 2 of minute hand pipe in long ventilation seat mouth 7 on the hour hand base, ventilation leather hose 6, the minute hand base connect to form long airway.

Fluid-through tube road 5, logical liquid leather hose 15, the interior fluid-through tube road 14 of hour hand base, hour hand pipe 11 inner chambers connect to form the fluid-through tube road in minute hand pipe 1 inner chamber, the minute hand base.

During use, minute hand pipe 1 thrusts the infusion bottle plug, minute hand canister aperture 2 enters in the bottle, and hour hand pipe 11 thrusts in the powder bottle, and hour hand canister aperture 10 enters in the bottle stopper, long ventilation seat mouth 7 on the hour hand base is socketed in the trachea of air pump, go out air cock by air pump, gas is entered in the infusion bottle by filtration by long airway, and medicinal liquid enters in the powder bottle by the fluid-through tube road, by the air inlet switch, the just former road of medicinal liquid is returned in the infusion bottle.
