Abstract
The utility model provides a liquid medicine feeding device used in clinic, which is composed of a negative pressure pump and a disposable infusion pipe. The utility model is characterized in that the disposable infusion pipe is formed by connecting a medicine sucking pipe, an air pumping pipe and a drip pipe on the needle head of an infusion pipe with two holes and three joints, wherein, a vent hole is communicated with the medicine sucking pipe, and a drip hole is communicated with the air pumping pipe and the drip pipe. When medicine is fed, the needle head is inserted into a liquid bottle, the air pumping pipe is connected with the negative pressure pump which is started to extract gases in the liquid bottle from the air pumping pipe, so that air pressure in the liquid bottle is smaller than the atmospheric pressure. A needle head for sucking medicine is inserted under the liquid surface of liquid medicine in a liquid medicine ampoule, and the liquid medicine enters the liquid bottle under the function of the atmospheric pressure via the medicine sucking pipe.
Description
This utility model relates to a kind of liquid chemicals dosing plant of clinical use.
At present, medical circle is the treatment means of intravenous drip as a kind of routine, before carrying out intravenous drip to patient, usually in liquid bottles, add the medicinal liquid that the state of an illness needs by doctor's advice, the nursing staff must carry out strict aseptic manipulation, put syringe needle with asepsis injector, syringe needle inserted under the liquid level in ampoule or the air-tight bottle inhale medicine, again medicinal liquid is injected in the liquid bottles, add multiple medicinal liquid as need, will repeat aforesaid operations, dosing finishes, and one-time infusion tube is inserted carry out intravenous drip in the liquid bottles.This artificial adding method thereof is complex operation not only, and violate the aseptic operation principle easily, cause liquid medicine contamination, be cause infusion reaction clinically protect source property unsafe factor, on the other hand because manually-operated efficient is low, can not as early as possible multiple medicinal liquid be added in the liquid bottles and instil, influence is rescued the timely medication of patient.
The goal of the invention of this device is to provide a kind of pollution section few to clinical, liquid chemicals dosing plant simple to operate.
Device is made up of negative pressure pump and one-time infusion tube.This one-time infusion tube comprises tube for transfusion syringe needle, medicine absorbing tube, exhaust tube, drip tube.The tube for transfusion syringe needle is two holes, three joints, connects medicine absorbing tube respectively, exhaust tube, and drip tube, the steam vent that wherein is positioned at needle point communicates with medicine absorbing tube, and the instillation hole on the shank communicates with exhaust tube and drip tube.
When adding medicinal liquid, in the tube for transfusion syringe needle insertion liquid bottles with one-time infusion tube, shut the water producing clip of drip tube, exhaust tube connects negative pressure pump, starts negative pressure pump, and the interior gas of liquid bottles is continuously extracted out from instillation aperture exhaust tube.At this moment the liquid bottles internal gas pressure is less than atmospheric pressure, and the suction medicine syringe needle on the medicine absorbing tube is inserted under the medicinal liquid liquid level in the medicinal liquid ampoule, and medicinal liquid enters in the liquid bottles by medicine absorbing tube under atmospheric effect.After medicinal liquid adds, exhaust tube and negative pressure pump are separated, shut the water producing clip on the exhaust tube, can carry out vein and drip the master.
Because the instillation hole is on the shank of tube for transfusion syringe needle, separate with steam vent at needle point, so the medicinal liquid that comes out from steam vent can fall because of gravity and inertia, can not be inhaled into the instillation hole.
For preventing that the impurity in the medicinal liquid from entering in the liquid bottles, at the built-in micropore filtering film of medicine absorbing tube.
This device has following advantage:
1. need not manual operations, simple and convenient, realize the automatization in the dosing process;
2. in the dosing process, medicinal liquid only passes through one-time infusion tube, reduces medicinal liquid contaminated link in the dosing process;
3. the micropore filtering film in the medicine absorbing tube can prevent that the impurity in the medicinal liquid from entering in the liquid bottles.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing invention is further described:
The one-time infusion tube that this device uses is by tube for transfusion syringe needle (9), drip tube (1), exhaust tube (3), medicine absorbing tube (8) is formed, tube for transfusion syringe needle (9) is two holes, three joints, connect medicine absorbing tube (8) respectively, exhaust tube (3) and drip tube (1), the steam vent (10) that wherein is positioned at needle point communicates with medicine absorbing tube (8), instillation hole (5) on the shank communicates with exhaust tube (3) and drip tube (1), the built-in micropore filtering film of medicine absorbing tube (8) (7), terminal band is inhaled medicine syringe needle (11), exhaust tube (3) band water producing clip (2).
Tube for transfusion syringe needle (9) is inserted liquid bottles (6), exhaust tube (3) is opened water producing clip (2) after joining with negative pressure pump (4), again the water producing clip of drip tube (1) (not drawing among the figure) is shut, start negative pressure pump (4), make the air in the liquid bottles (6) continuously enter tube for transfusion syringe needle (9) from instillation hole (5), extract out from negative pressure pump (4) through exhaust tube (3) again, at this moment the bottle internal gas pressure is less than atmospheric pressure, can carry out the liquid dosing, under the medicinal liquid liquid level of inhaling in medicine syringe needle (11) the insertion medicinal liquid ampoule (12), medicinal liquid will be from inhaling medicine syringe needle (11) under atmospheric effect, through medicine absorbing tube (8), micropore filtering film (7), tube for transfusion syringe needle (9) is entered in the liquid bottles (6) by steam vent (10) at last.Because instillation hole (5) is positioned on the shank of tube for transfusion syringe needle (9), separate with steam vent (10) at needle point, so the medicinal liquid that comes out from steam vent (10) can fall because of gravity and inertia, can not be inhaled into instillation hole (5).The built-in micropore filtering film (7) of medicine absorbing tube (8) can prevent that the impurity in the medicinal liquid from entering in the liquid bottles (6).Dosing finishes, and exhaust tube (3) and negative pressure pump (4) are separated, and shuts water producing clip (2), can carry out intravenous drip, and medicine absorbing tube during instillation (8) is used for aerofluxus.
Claims (3)
1. liquid chemicals dosing plant, form by negative pressure pump (4) and one-time infusion tube, it is characterized in that: this one-time infusion tube comprises tube for transfusion syringe needle (9), medicine absorbing tube (8), exhaust tube (3) and drip tube (1), tube for transfusion syringe needle (9) are two holes, three joints, connect medicine absorbing tube (8) respectively, exhaust tube (3) and drip tube (1), the steam vent (10) that wherein is positioned at needle point communicates with medicine absorbing tube (8), and the instillation hole (5) on the shank communicates with exhaust tube (3) and drip tube (1); Negative pressure pump (4) joins with exhaust tube (3).
2. liquid chemicals dosing plant according to claim 1 is characterized in that: the steam vent (10) on the one-time infusion tube syringe needle (9) separates with instillation hole (5), and steam vent (10) is at needle point, and instillation hole (5) are at shank.
