Abstract

The utility model provides an exchange device which can be used to connect a plastic dextrose infusion bottle and a penicillin phial, comprising an exchange body, a hollow needle tube whose both ends are provided with sharp orifices in the body and a plastic case whose shape is similar to a bottle cap. Dextrose liquid is injected into the penicillin medicine phial to dilute medicinal powder via the utility model at the operation time; the plastic infusion bottle is pressed by a hand, the procedure of injection, mutual thawing and resorption of medical liquid can be completed via the force generated by gas flow. The utility model has the advantages of no cross infection, labor saving and time saving in dispensation.

Description

Once-used liquid medicine exchanger

This utility model relates to a kind of chemicals dosing plant relevant with the human transfusion apparatus.

During venous transfusion,, need in Glucose Liquid, to add medicines such as penicillin clinically for reaching therapeutic purposes.But inject 10 to 20 bottles of medicine as many as in one bottle of Glucose Liquid.The method that adopts is at present, extracts Glucose Liquid earlier with syringe, injects medicine bottle and rocks the messenger drug dissolving, extracts admixing medical solutions again out and refills in the Glucose Liquid, and repeatable operation is until having joined all medicines.This mode easily makes rubber grain fall in the liquid, and causes cross infection easily owing to repeatedly use syringe and repeated localised puncture rubber bottle cap, causes infusion reaction.The labor intensity that makes up a prescription is big, and the time is long, and in medium-sized or above hospital, making up a prescription morning generally needs 2 hours approximately.

The purpose of this utility model provides a kind of simple in structure, and is with low cost, nonrecoverable airtight dispensation apparatus, and it can simplify aforesaid operations effectively.

The purpose of this utility model is achieved in that to be inserted in the middle of the round plastic bottle cap and all there is the piercing needle of oblique angle cutting edge at bonding two ends, has constituted the medicinal liquid exchanger.When making up a prescription, one at syringe needle inserts Glucose Bottle Cap, and medicine bottle is inserted in the other end, and messenger drug mixes.After making up a prescription, the pin that inserts in the glucose is motionless, as long as change medicine bottle, can join another kind of medicine.

This utility model only needs to insert the Glucose Liquid bottle once with syringe needle, can repeatedly make up a prescription, and avoids repeated localised puncture rubber bottle cap.Making up a prescription is to carry out in airtight needle tubing, and the disposable use of medicinal liquid exchanger has reduced infection chance.Easy to operate, improved the speed of making up a prescription, save time.Because simple in structure, cost is low, and is practical, be convenient to clinical generally use.

The utility model concrete structure is provided by following examples and accompanying drawing.

Fig. 1. be this utility model section of structure.

Fig. 2. be the exchanger arrangement vertical view.

Fig. 3. be the exchanger work sheet.

Describe concrete device details and the working condition that the utility model proposes in detail below in conjunction with Fig. 1.

This device comprises a round plastic bottle cap body (2), strengthens and the contact surface of puncture needle (3), (4) at round platform of bottle cap (2) bottom protrusion, increases the firmness of connection.The height of puncture needle (4) is lower than the bottle cap height, and the degree of depth that the control pin enters phial makes the complete sucking-off of medicinal liquid.

As shown in Figure 2, puncture needle is at the bottle cap center.

In conjunction with Fig. 3 this utility model operational approach is described.

Earlier plastic infusion bottle (8) is erected, hand-held exchanger plastic bottle closure (2) all thrusts syringe needle (3) in infusion bottle (6) mouth, getting penicillin phial (5) inserts bottleneck to syringe needle (4), integral body keeps flat and grasps plastic infusion bottle (6) extruding secondary, medicinal liquid is entered in the penicillin by needle tubing, dissolve penicillin powder, push infusion bottle again, utilize the negative pressure in the infusion bottle that the medicinal liquid in the penicillin bottle is sucked back infusion bottle, finish the work of making up a prescription.

Claims (1)

1, a kind of medicinal liquid exchanger that connects glucose plastic infusion bottle and penicillin phial with puncture needle, it is characterized in that a round plastic bottle cap (2), a platform is protruded at the middle part, a center casting hole (1), two ends all have needle tubing (3), (4) of oblique angle cutting edge to pass hole (1) and bottle cap (2) is bonded into one.
