The utility model content
The purpose of this utility model provides a kind of transfusion drug feeding device, and the infusion bottle bottle stopper only need puncture once, and many bottles of injectable powder bottle stoppers all puncture once to finish and absorb dosing, greatly reduces the plug particle number.And be not subjected to the solvent quantity not sufficient during dosing, aspirate halfway restriction, can fill with medicine bottle, fully dissolving also can repeat to absorb process in case of necessity.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of transfusion drug feeding device, comprise needle body, dual pathways needle point, single channel needle point and syringe interface, it is characterized in that: needle body inside is provided with left hollow channel and right hollow channel, described left hollow channel one end is communicated with syringe interface, and the other end is communicated with dual pathways needle point; Right hollow channel one end is communicated with dual pathways needle point, the other end is communicated with the single channel needle point.Insert medicine bottle bottle stopper and infusion bottle bottle stopper during use respectively, syringe interface connects syringe, utilizes the piston pull of syringe to inject, and inner liquid and air can circulate, and can realize that the powder pin absorbs the dosing process.
Another technical scheme that its technical problem that solves this utility model adopts is: a kind of transfusion drug feeding device, comprise needle body, dual pathways needle point, single channel needle point, syringe interface and transfusion catheter, it is characterized in that: needle body inside is provided with left hollow channel and right hollow channel, described left hollow channel one end is communicated with syringe interface, and the other end is communicated with dual pathways needle point; Right hollow channel one end is communicated with dual pathways needle point, the other end is communicated with the single channel needle point; Described right hollow channel is connected with the single channel needle point by transfusion catheter.
Between described transfusion catheter and the single channel needle point defecator is arranged, the plug microgranule that may occur with filtering.
Described dual pathways needle point has a stopping means, is beneficial to the medicinal liquid in abundant suction, the emptying medicine bottle.
Owing to adopted two bottle stopper puncture needles to be connected with infusion bottle with medicine bottle in the above-mentioned solution with syringe, form passage with the extraneous internal run-through that seals, particularly utilize syringe piston to inject, can accelerate the injectable powder dissolution velocity with the medicated powder in the circulating fluid repeated stock medicine bottle by the medicine bottle bottle stopper puncture needle of dual pathways needle point.Powder pin injection absorbs the dosing process and can finish in the inside of sealing, and all bottle stoppers only need puncture and once can finish whole dosing process, greatly reduce the contaminated probability of plug particle number and medicinal liquid.
The invention has the beneficial effects as follows: it is simple in structure, and all bottle stoppers only need puncture and once can finish whole dosing process, greatly reduce the contaminated probability of plug particle number and medicinal liquid.
