Description

A kind of liquid dispensing device

Technical field

This utility model relates to molten medicine, dosing, liquid getting device in a kind of medicine configuration, is used for adding medicine or taking out liquid at infusion bottle or transfusion bag.

Background technology

At present, most clinically hospitals are all continuing to use traditional syringes dosing method, dispose intravenous fluids usually and are medicinal liquid from little ampoule or closed phial suction syringe; And then the adding infusion bottle, if no matter also dissolving earlier of injectable powder is dissolving medicated powder or dosing; The syringe transmission all will be passed through in the centre, has increased workload, many dosings also need aspirate repeatedly, puncture bottle stopper or loading and unloading syringe needle; Not only directly or indirectly increase syringe needle and pintle piston and expose the chance of polluting; And cause the pollution of hands easily, also, damage to patient because the repeated localised puncture plug causes liquid medicine contamination easily and brings particulate matter into to medicinal liquid.It also is by the extraction of syringe one pin one pin that excess liquid in the infusion bottle is extracted out, also causes the generation of the problems referred to above easily.

Transfusion is widely used clinical as the important means of treatment various diseases, because amount of infusion is big, and nurse shortages; The molten medicine of every day, dosing, drawing liquid occupy nurse's great amount of time; If by the operation standard of hand syringes in " basic nursing ", the operational approach of the untouchable syringe piston aspiration medicinal liquid of both hands is difficult to accomplish dosing, the dosing work of every day in the real work; Not only efficient is low, and causes the fatigue of hands easily.Have investigation to show that most nurses can not strict rule of operation hand syringes aspiration medicinal liquid by standard, in addition in the operation because careless manipulation also can cause the waste of medicinal liquid.Also had many experts to invent various medicine dissolving devices in recent years, what have costs an arm and a leg, and the operation inconvenience that has is not applied based on a variety of causes.

The utility model content

The purpose of this utility model is exactly to solve the problems referred to above that exist in the prior art; A kind of liquid dispensing device is provided; Use this liquid dispensing device in infusion bottle or transfusion bag, to add medicine and perhaps take out liquid, puncture time is few, and the probability that particulate matter produces is little; Clinical application safety is high, high efficiency.

Be to realize above-mentioned purpose, the technical solution of this utility model is: a kind of liquid dispensing device, and it comprises single chamber syringe needle or two-chamber syringe needle I, one, two or more two-chamber syringe needle II, filter A, filter B; Two passages are arranged in the housing of two-chamber syringe needle I or two-chamber syringe needle II: passage A, channel B, passage A is the passage of medicinal liquid circulation, and channel B is a venting channels, and passage A and channel B top mouth are opened on the sidewall at housing needle point place, and opening section is the inclined-plane; The channel B end connects air filter B by air line, and the other end of air filter B connects seal cover by air line; The terminal outer wall of passage A, the terminal outer wall of channel B and filter B are crimped in the hand-held base; In the syringe needle of single chamber a passage is arranged, have one, two or more and the cross section inclination liquid-through hole of channel connection on its syringe needle sidewall, single chamber syringe needle end outer wall is fixed with needle stand; The passage A of single chamber syringe needle channel end or two-chamber syringe needle I is terminal connect behind the filter A through two logical, threeway or many logical and soft fluid-through tube road respectively with one, terminal connection of passage A of two or more two-chamber syringe needle II.

This utility model also comprises sacculus, sacculus by fluid-through tube road and soft fluid-through tube road be communicated with filter A and two logical, threeway or many logical between.

Indicate scale above the above-mentioned said sacculus, to know the amount of from liquid bottles, taking out liquid accurately.

This utility model also comprises the fluid pipeline card, and it is connected on the above-mentioned described soft fluid-through tube road, and during clamping, liquid does not circulate, when opening, and liquid communication.

When dissolving medicine, single chamber syringe needle or two-chamber syringe needle I are inserted in the liquid bottles, two-chamber syringe needle II is inserted in little ampoule or the closed phial; The operator directly pushes flexible package liquid bottle (bag) with hands, in the little ampoule of inflow or closed phial that liquid can be unobstructed, for instant medicine; Need not extract syringe needle; Shake bottle gently, raise after the dissolving and be inverted little ampoule or closed phial, the medicinal liquid after the dissolving gets final product pumpback in liquid bottles; Perhaps push repeatedly, loosening liquid bottles, make medicinal liquid pumpback after the dissolving in liquid bottles.For being difficult for dissolved drug, also can extract syringe needle, after the use agitator shakes up dissolving, pumpback again.If need many medicines of dissolving; Can use this utility model with two or more two-chamber syringe needle II; If there is not supporting this utility model; The quantity that can use two-chamber syringe needle II is than adding this utility model that little ampoule or closed phial quantity are Duoed, as long as use the fluid pipeline card with the clamping of obsolete two-chamber syringe needle II.

The beneficial effect of this utility model: reduce puncture time, reduce the generation of particulate matter; The closed operation reduces pollution section, improves clinical application safety; The standard nurse operation is increased work efficiency; Practice thrift medical resource, easy to utilize.
