Abstract
A dosing apparatus with double cavities belongs to medical instruments. The utility model mainly resolves the dosing problem in the time of transfusion. The technical scheme of the utility model includes that the two ends of a double-cavity tube are respectively connected with a double-cavity needle, one needle cavity and one cavity of a double-cavity tube which are disposed on the same side are communicated. The dosing can be realized by one puncturing, thereby the utility model has the advantages that the operation is simple and convenient, the labor intensity of medical-care personnel is reduced, and the sanitation and pollution avoidance of the medicine fluid are guaranteed simultaneously. Pluralities of puncturing holes can not be formed on a bottle stopper of a transfusion bottle, thereby the leak through is avoided. The utility model is in particular adaptable for the utilization of a nurse station in hospitals.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically is a kind of drug feeding device.
Background technology
Often powdery medicine need be made solution in the clinical treatment process, the better medicinal liquid of dissolving is injected in the infusion bottle.At present, dosing in infusion bottle need be injected liquid earlier with syringe in the phial that powdered drug is housed, and makes it fully to dissolve to make medicinal liquid by rocking phial then.Medicinal liquid shakes up the sucking-off from phial of back reuse syringe, to inject infusion bottle.The medicament categories that needs if make up a prescription is many, this dosing method trivial operations, and efficient is low, and labor intensity is big.After operator's fatigue, take syringe, promptly hold pintle grabbing greatly easily, further cause needle interior wall to pollute medicinal liquid thereby cause pintle to pollute like this.And the syringe needle repeated localised puncture, in piercing process, cut bottle stopper, produce many small particles, these small particles can be fallen in the medicinal liquid, finally can be input to human body, and certain danger is arranged, and are unfavorable for patient's rehabilitation.After the bottle stopper of infusion bottle suffers repeated localised puncture in addition, cause water clock easily.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of two-chamber drug feeding device, and its one-time puncture can be realized molten medicine, dosing, simple to operation, health.
The technical solution of the utility model is: two-chamber drug feeding device, the two ends of a double lumen tube connect a two-chamber syringe needle respectively, and the syringe needle chamber of the same side communicates with the two-chamber tube chamber of the same side.
As further technical scheme of the present utility model: described two-chamber syringe needle is provided with hand-held piece.
Be covered with needle cap on the described syringe needle.
Technical scheme further: the described double lumen tube that links together, two-chamber syringe needle and needle cap place in the aseptic package bag.
Two pin holes of described two-chamber syringe needle are positioned at the cylinder both sides of syringe needle.To prevent to cut the microgranule obstruction pin hole that bottle stopper produces.
During use, with the two-chamber syringe needle insertion infusion bottle of an end, the two-chamber syringe needle of the other end inserts phial.Earlier infusion bottle is raised, the liquid in the infusion bottle is transported in the phial by a road of double lumen tube.Meanwhile, a gas passage is formed on another road of double lumen tube between infusion bottle and phial, and two bottles of internal gas pressures are equated.
After the medicine dissolving, medicinal liquid is shaken up, raise phial then, the medicinal liquid in the phial is transported in the infusion bottle by double lumen tube one tunnel, and another road of double lumen tube then becomes gas passage.
The beneficial effects of the utility model are: it only needs one-time puncture can realize dosing, and is simple to operation, has alleviated medical personnel's labor intensity, has guaranteed simultaneously that also the medicinal liquid health is pollution-free.Can on the bottle stopper of infusion bottle, not form a plurality of puncturing holes, thereby avoid causing water clock.

Fig. 4 is the structural representation of this utility model embodiment two.
Fig. 5 is the structural representation of this utility model embodiment three.
Among the figure: 1 two-chamber syringe needle, 2 double lumen tubes, 3 hand-held pieces, 4 needle cap, 5 aseptic package bags, 6 infusion bottles, 7 phials.
The specific embodiment
Embodiment one: as shown in Figure 1, this two-chamber drug feeding device mainly comprises two-chamber syringe needle 1, double lumen tube 2.Two-chamber syringe needle 1 and double lumen tube 2 are integral type.
The two ends of double lumen tube 2 connect a two-chamber syringe needle 1 respectively, and the syringe needle chamber of the same side communicates with the two-chamber tube chamber of the same side, and two pin holes of syringe needle are positioned at the top.Double lumen tube 2 is for having the plastic flexible pipe of two-way cavity.Described two-chamber syringe needle 1 is provided with hand-held piece 3, is convenient to grip syringe needle by hand-held piece 3.For the protection syringe needle, be covered with needle cap 4 on the described two-chamber syringe needle.Above-mentioned two-chamber drug feeding device integral body places in the aseptic package bag 5.
During use, open aseptic package bag 5, take off two needle cap 4.As shown in Figure 2, pinching hand-held piece with hands inserts two-chamber syringe needle 1 respectively in infusion bottle 6 and the phial 7.Raise infusion bottle 6 then, one road inner chamber of double lumen tube 2 is formed infusion channel, and another road becomes gas distribution channel, makes two bottles of internal gas pressures balance gradually.
As shown in Figure 3, after the powdered drug dissolving, medicinal liquid is shaken up in the phial 7, raise phial 7 then, this moment, medicinal liquid entered in the infusion bottle 6 through one road inner chamber of double lumen tube 2, and another road has become gas distribution channel.Like this, one-time puncture just can be realized medicine dissolving and adding, has simplified operation.
When liquid communication is not smooth, can push double lumen tube 2.
Embodiment two: as shown in Figure 4, be that with embodiment one difference among this embodiment, two-chamber syringe needle and double lumen tube are split type.Its operation principle is with embodiment one.
Embodiment three: as shown in Figure 5, be with embodiment one difference that among this embodiment, two pin holes of described two-chamber syringe needle are positioned at the cylinder both sides of syringe needle, to prevent to cut the microgranule obstruction pin hole that bottle stopper produces.Its operation principle is with embodiment one.
