One cavity of one end of the main guide pipe is provided with a water inlet and outlet hole, and the other cavity of the main guide pipe is provided with a joint connected with the pressure adjusting device. The other cavity of the other end of the main guide pipe is provided with an air inlet and an air outlet holes. An air filter is respectively arranged on the end of each of the air inlet and the air outlet holes. The pressure adjusting device is a container which can be pulled and compressed. The utility model has the advantage that the medicine adding device for intravenous transfusion can simplify a medicine adding process, reduce time, enhance work efficiency, prevent medicine leakage, ensure an accurate medicine dosage and protect medical personnel from harm by medicine.

Description

The venous transfusion drug feeding device

This utility model relates to a kind of medical apparatus and instruments, in particular for the infuse venous transfusion drug feeding device of usefulness of patient.

At present, venous transfusion is a treatment means the most frequently used in the medical treatment.In the clinical treatment of hospital, a large amount of venous transfusion work is all arranged every day, need the medicine of various injectable powder types is added in 5% liquid of glucose or normal saline of 500ml, the input human body plays therapeutical effect.So far this is performed such the intravital process of injectable powder medicine adding Glucose Liquid: (1) opens the water for injection of a 5ml dress, (2) with syringe water for injection is drawn in the syringe, (3) water for injection in the inhalation syringe is injected in the medicine bottle of injectable powder, (4) the medicine sucking-off that the reuse syringe will dissolve after the vibration, (5) are re-introduced into the medicine in the inhalation syringe in 5% liquid of glucose of 500ml.Each process needs 3-4 minute approximately, and need repeat above process nearly 100 times every day, wastes time and energy.Tend to take place the leakage of medicine in this process, the medicine of syringe is infected with in addition, can cause the dose deficiency, affects the treatment; And can cause the local environment pollution, some medicine (as antitumor drug) can work the mischief to medical worker's health.And transfusion bottle stopper through repeatedly the puncture, its chip can cause harmful effect to the patient as falling in the liquid.

The purpose of this utility model is to disclose a kind of cumbersome in order to solve the dosing process at aforementioned the deficiencies in the prior art; alleviate nurse's workload; save time; raise the efficiency; prevent the medicine leakage; guarantee the accuracy of drug dose, the protection staff avoids the venous transfusion drug feeding device of the harm of medicine.

This utility model is realized as follows: the venous transfusion drug feeding device, it is made up of main pipe 8 and syringe 3, wherein: the two ends of main pipe 8 are double lumen, hold a chamber that one paddle hole 5 is arranged at the A of main pipe 8, there is a joint 4 in another chamber, in another chamber of the B of main pipe 8 end port 6 and port 7 is arranged.

Good effect of the present utility model is: the application of venous transfusion drug feeding device can be simplified the dosing process, the shortening time, increase work efficiency, and also can prevent the leakage of medicine, thereby guarantee the accurate of medication amount that the protection medical worker avoids the harm of medicine.

Description of drawings is as follows:

Fig. 1 is a structural representation of the present utility model.

Wherein:

1. powder injection bottle 2. Fructus Vitis viniferae sugar flask 3. pressure regulators 4. joints

5. paddle hole 6.7. port 8. main pipes 9. air filtrates

Below in conjunction with accompanying drawing this utility model is described in further detail:

As shown in Figure 1.The venous transfusion drug feeding device, it is made up of main pipe 8 and pressure regulator 3, and wherein: the two ends of main pipe 8 are double lumen, hold a chamber that one paddle hole 5 is arranged at the A of main pipe 8, and there is a joint 4 in another chamber, links to each other with pressure regulator 3.There are port 6 and port 7 in another chamber at the B of main pipe 8 end.Put an air filtrate at port 7 ends, with filtered air, pressure regulator 3 is one can stretch and draw and compressible container.Its work process is as follows: the A end of drug feeding device is inserted in the powder injection bottle 1, below the water surface in the B end insertion Fructus Vitis viniferae sugar flask 2.When pull pressure regulator 3, produce negative pressure in the powder injection bottle 1, the paddle hole 5 of the liquid in the Fructus Vitis viniferae sugar flask 2 on main pipe 8 can be drawn in the powder injection bottle 1.And reduce owing to liquid reduces the pressure that forms in the Fructus Vitis viniferae sugar flask 2, can keep balance with atmospheric pressure by port 6,7 air inlets.Rock a little, make the dissolving of powder injection bottle 1 Chinese medicine, push pressure regulator 3 again, make to produce malleation in the powder injection bottle 1, the medicinal liquid that dissolves is flow in the Fructus Vitis viniferae sugar flask 2 through paddle hole 5, and the pressure in the Fructus Vitis viniferae sugar flask 2 changes, can obtain adjusting through port 6,7.So far, whole dosing process is finished, and only needs for tens seconds.As also having a small amount of residual drug in the powder injection bottle 1, can repeat aspiration, pushing once gets final product.If need in same liquid of glucose, to add several bottles of medicines, only need the A end of drug feeding device is inserted another medicine bottle, repeat above process and get final product.
