Abstract

The utility model belongs to a medical appliance, particularly an intravenous medicine-fed infusion device. The existing infusion device is composed of a porous plug, an air inlet tube with a filter net and a protective jacket and a mouthy type dropper with a switch and an infusion needle head. The difference between the utility model and the existing infusion device is that the two-hole plug is changed into a three-hole plug, the outer connection tube of the holes is communicated with a medicine-fed tube with an infusion needle head and a switch, and the air inlet tube is provided with a switch. The pressure in an infusion bottle is in a positive pressure state and a negative pressure state through the switches on the three tubes and the air inlet tube. When the pressure is in the positive pressure, the medicine is diluted through the medicine-fed tube in infusion. When the pressure is in the negative pressure, the diluted medicine flows back to the infusion bottle through the medicine-fed tube. Many times of puncturing the infusion bottle are avoided in feeding medicine, and the pollution chances are reduced.

Description

The vein medicine-supplementing transfusion device

This utility model belongs to a kind of medical apparatus and instruments, especially relates to a kind of vein medicine-supplementing transfusion device.

The traditional way of clinical transfusion is to inject the apothecary jar that institute should dilute after drawing diluent with the empty needle pipe, treat that medicine fully dissolves after, resorb is former to inject infusion bottle with needle tubing, operating process is simple, easily grasp.But under the situation that does not have enough big volume empty needle pipe, trouble, complexity seem again.Need the repeated localised puncture Infusion bottle lid, easily cause the bottle stopper microgranule to come off, both increased pollution and sensitization chance, increased nurse's labor intensity again.

The disclosed purpose of this utility model be exactly provide at the deficiency of above-mentioned intravenous transfusion device pass through the just vein medicine-supplementing transfusion device of dosing repeatedly of porous plug one-time puncture Infusion bottle lid.

A kind of vein medicine-supplementing transfusion device, by porous plug 1, have drainage screen 3 and sheath 5 air inlet pipe 2, have switch B7 and an infusion needle 8 is it possible that formula dropper 6 form, it will be levied and be: porous plug 1 is three holes, wherein has a hole to be communicated with the chemical feed pipe 9 that has switch C10 and Medicated needle of syringe 11.

According to above-described a kind of vein medicine-supplementing transfusion device, its feature also is: have on the air inlet pipe 2 of drainage screen 3 and sheath 5 and have gauge tap A4.

Fig. 1 is the overall structure sketch map of a kind of vein medicine-supplementing transfusion device of this utility model, wherein:

1---porous plug 2---air inlet pipe 3---drainage screen

4---switch A 5---sheath 6---is is it possible that the formula dropper

7---switch B 8---infusion needle 9---chemical feed pipes

10---switch C 11---Medicated needle of syringe

In conjunction with the accompanying drawings, the implementation procedure of a kind of vein medicine-supplementing transfusion device of narration this utility model:

A kind of vein medicine-supplementing transfusion device of this utility model is very single, just can realize as long as on the basis of former transfusion device, improve a little, specific practice is: change the plug (entering the hard tube plug of infusion bottle behind the most advanced and sophisticated puncture transfusion device bottle cap) of two pore area points of former transfusion device into three hole plugs, and the eyelet that increases newly that is in the bottle outside is communicated with a connection tube, will have chemical feed pipe 9 that a gauge tap C10 and an end have a Medicated needle of syringe 11 and never be inserted in the connection tube that increases newly and just can with an end of Medicated needle of syringe 11.Because the hard plug is three holes, can be made into symmetrical expression in the actual processing, the centre is a dripping hole, and two side holes one is an air inlet, and one for adding the medicinal liquid hole, and two holes can exchange when mounted each other.For ease of dosing or with the required medicine powder that adds of the solution dilution in the infusion bottle, should establish a gauge tap A4 on the air inlet pipe 2.Medicated needle of syringe 11 is general injection needle, and three gauge taps are identical, and the used switch of transfusion device is the same with now using, and tee pipe is all identical with the existing pipe of using, transparent hose, and place three switches, and infusion needle 8, drainage screen 3, sheath 5 also with existing identical, repeat no more.

Using method:

Pricker breaks infusion bottle and should dilute the bottle cap of medicine, routine disinfection, open the transfusion device packing, take out transfusion device, porous plug 1 is inserted in the infusion bottle, close on the chemical feed pipe 8 gauge tap C10 and is it possible that the gauge tap B7 on the formula dropper 6, get the suitable empty needle pipe of a volume, back out the sheath 5 that is enclosed within air inlet pipe 2 ends, in infusion bottle, inflate pressurization by air inlet pipe 2 with the empty needle pipe, when pressure suits, close the switch A4 on the air inlet pipe 2.Take off the sheath on the Medicated needle of syringe 11, Medicated needle of syringe 11 is inserted in the medicine bottle that should dilute, open switch C10, the liquid in the infusion bottle flows into medicine bottle automatically, when flow of liquid is enough a certain amount of, close switch C10, open switch A4 again, by air inlet pipe 2 gas of infusion bottle is extracted out again with former inflation empty needle pipe, after making it to become negative pressure, close switch A4, open switch C10, institute's dilute liquid medicine just flows in the infusion bottle by Medicated needle of syringe 11 and chemical feed pipe 9.During the practical application operation, once can dilute or suck some bottle liquid medicines simultaneously.Close switch C10 at last, open on the air inlet pipe 2 switch A4 and is it possible that the switch B7 on the formula dropper 6, the gas in the tube for transfusion of draining, operation is infused routinely.

A kind of vein medicine-supplementing transfusion device of this utility model, reasonable in design, simple to operate, a people one pipe when having guaranteed transfusion has been avoided repeated puncture, has reduced opportunities for contamination, has alleviated nursing staff's labor intensity.Owing to adopted tee pipe three on-off control, can also carry out pressure transfusion in case of necessity.

Claims

1, a kind of vein medicine-supplementing transfusion device, by porous plug 1, have drainage screen 3 and sheath 5 air inlet pipe 2, have switch B7 and an infusion needle 8 is it possible that formula dropper 6 form, it is characterized in that: porous plug 1 is three holes, wherein has a hole to be communicated with the chemical feed pipe 9 that has switch C10 and Medicated needle of syringe 11.

2, a kind of vein medicine-supplementing transfusion device according to claim 1, its feature also is: have on the air inlet pipe 2 of drainage screen 3 and sheath 5 and have gauge tap A4.
