Abstract

The utility model relates to an intravenous infusion medicine feeding device. A trifurcate pipe is connected with an infusion pipe, the trifurcate pipe is connected with a one-way valve, sweet water in an infusion bottle is continuously absorbed into a powder bottle to be diluted through the absorption of an absorbing needle cylinder, and medicine powder needing adding in the infusion bottle is repeatedly dissolved and flushed and flows into the infusion bottle. The utility model has the advantages of simple structure and novel design, the whole process is circulated in a closed system, pollution caused by the dilution of the medicine powder when liquid is pumped is reduced, the working time of medical staff is saved, and the work efficiency is improved.

Description

Intravenous infusion medicine-feeding device

The present invention relates to medical instruments field, be specially adapted to the chemicals dosing plant of infusing.

Medical department often need add medicine powder to infusion bottle (being generally glucose or saline solution) when giving patient infusion, the method that generally adopts is that the aluminium lid of infusion bottle and powdered medicine bottle is pried open with shears or other apparatuses at present, partly carry out disinfection with the serum cap of alcohol swab to two bottles of exposures, respectively to infusion bottle, powdered medicine bottle inserts No. 12 or No. 16 syringe needles fell infusion bottle, syringe is sucked gas, connect the infusion bottle syringe needle, push gas liquid in the infusion bottle is extracted out, separate syringe and syringe needle, syringe is connect the powder bottle syringe needle, inject liquid 3-4ml, gas bleeding is extracted syringe and to be inserted next powder bottle again together with syringe needle, inject liquid, go on one by one according to this, after powder bottle is all injected liquid, take to leave standstill, the method of rocking or vibrating, medicated powder is all dissolved, and then sterilization is once inserted powder bottle with syringe needle one by one again, the sucking-off medicinal liquid, the infusion bottle that reinjects is plugged tube for transfusion, instils to venous patient.

This operational approach is cumbersome, time-consuming, and the continuous plug of syringe needle pollutes easily in addition, and whole medicinal liquids in the sucking-off powder medicine bottle, causes the waste of medicinal liquid.

Task of the present utility model is to design a kind of airtight pumping device, reduces operational pollution, the formality that simplifies the operation, saves the operating time, dissolving powder process is all finished in an obturator.

Fig. 2 is UNICOM's pin sketch map

Fig. 3 is another embodiment of this device

Introduce technology contents of the present utility model below in conjunction with accompanying drawing:

To close tube for transfusion switch (3) in this device access infusion pipeline, at this moment pipeline is closed state, when moving down, the piston of syringe (5) forms negative pressure in the pipeline, liquid in the infusion bottle (1) enters Y-pipe (6) via tube for transfusion (2) by check valve (4), when syringe (5) when moving up, check valve (4) is closed, check valve (7) is opened, liquid enters powdered medicine bottle through feed liquor syringe needle (8) in the Y-pipe (6), along with syringe (5) reciprocating motion of the pistons, the powder bottle herb liquid will enter each powdered medicine bottle one by one by UNICOM's pin (9), and the medicinal liquid after dissolving is got back in the large transfusion bottle (1) through feeding back pipe (10), all clutch tube for transfusion (2) or inverted infusion bottle is vertical after the dissolving when powder bottle medicated powder, push-and-pull needle tubing (5) just can make the medicinal liquid in the powder bottle all enter in the infusion bottle (1).

Use this device that following advantage and effect are arranged:

One, reduced pollution.Because this installs all equipment disposable sterilization medicinal liquids and circulates in an airtight system, existing separation is connected extracts the insertion syringe needle repeatedly, has significantly reduced the opportunities for contamination that causes because of operation.

Two, save medicine, cut the waste, improve curative effect.Whole device does not have medicinal liquid and spills, the powder bottle medicine is fully diluted, because circulation dissolving, the medicine and the residual liquid concentration that residue on the powder bottle wall all are low than existing methods, medicine is all imported in the patient body like this, patient's actual therapeutic dose is more accurate, makes that medicine is fully utilized, effect is better.

Three, save time, raise the efficiency.Because this installs disposable complete operation preparation, reduced the number of times of syringe needle turnover powdered medicine bottle, save the time, improved work efficiency, reduced medical personnel's workload.

Embodiment of the present utility model is as follows:

Infusion bottle and the capping of powdered medicine bottle aluminum are pried open, routine disinfection, the breeches pipe (11) that takes out tube for transfusion is located little absorbent liquor ball and is pulled out Y-pipe (12) and locate little fur cap, this transfusion chemicals dosing plant leather hose (10) is connected on Y-pipe (11) to be located, this device leather hose (13) is inserted on the Y-pipe (12), syringe needle (8) is inserted first powdered medicine bottle, use UNICOM's pin (9) will need all powdered medicine bottles of dosing to be tied that (the long end of UNICOM's pin and syringe needle (8) are in first medicine bottle during connection respectively then, short end only inserts next, insert down successively then), after in the end inserting the hour hand of UNICOM's pin in powdered medicine bottle, syringe needle with feed tube (10) inserts in last powdered medicine bottle again, and guarantee that syringe needle contacted with the bottle end, the long end of reviewing and validate UNICOM's pin has been inserted into each powdered medicine bottle bottom, can carry out the operation sequence of medicated powder dilution, at this moment the sucrose solution of taking out in tube (5) infusion bottle of pushing pin will be by check valve (4), Y-pipe (6) and check valve (7) enter powdered medicine bottle, along with taking out the increase that pushes away number of times, medicated powder in each powdered medicine bottle dissolves gradually, at this moment pinch tube for transfusion (2) or inverted infusion bottle is vertical, make the sucrose solution in the infusion bottle (1) no longer enter Y-pipe (6), continue to take out the medicinal liquid of tube in (5) powder bottle of pushing pin and all to enter infusion bottle, at this moment only need from tube for transfusion Y-pipe (11), (12) locate to extract connection tube, locate to put into sea cotton ball at Y-pipe (11), Y-pipe (12) locates to cover little fur cap, locates to connect transfusion needle at tube for transfusion interface (14) and can instil to venous patient.

The check valve of this device adopts and connects the little rubber formation of marine products sphygomanometer on the airtight loculus inner sleeve.

UNICOM's pin is that a rustless steel hollow pipe that a, b, c three limits are arranged (bore is with 16 syringe needles) a length of side 45mm, b length of side 20mm, c length of side 25mm, a, 115 ° of the bent angles of b spring, b, the bent angle of c spring are 90 °.

Another embodiment of the present utility model such as Fig. 3, Y-pipe (6) connects check valve (4) and (7), check valve (4) other end connects liquid in-out twin-core pin (11), check valve (7) other end connects liquid in-out twin-core pin (8), the powder bottle of need dosing is pried open aluminum to seal, be inserted in after the sterilization on (8), infusion bottle is pried open be inserted on (11) after aluminum seals sterilization, take out the pipe (5) of pushing pin and just can will add infusion bottle (1) behind the powder bottle Chinese medicine dilution agent.

This apparatus structure is simple, making is easy, be suitable for plant produced, better economic and social benefit are arranged.
