Multifunctional transfusion automatic regulating device

Abstract

The invention relates to medical apparatus, especially relates to a multi-functional automatic moderation device for transfusion, comprising medicine preparation device, air exhauster and air passage conversion device; and said medicine preparation device comprises medical agent bottle, transfusion bottle, air conduit and long needle head. The two ends of liquid conduit are connected with needle head, and they are inserted into medical agent bottle and transfusion bottle to form liquid circuit. The air exhauster comprises air pump and air conduit, and the air passage conversion device is equipped with air conversion valve, valve core automatic driving device. The air passage conversion is also provided with air vent interface A, B, C, D, A is connected to air, C is connected with air exhauster, B and D are connected to medical agent bottle and transfusion bottle of medicine preparation device through air conduit and short needle head, respectively. When control valve core is connected with B, C, A and D, the liquid is transported to medical agent bottle from transfusion bottle, and when valve core is connected to A and B, C and D, the liquid refluxes from medical agent bottle to transfusion bottle. The invention is characterized buy simple operation, high efficient medicine preparation and no pollution.

Description

(1) Technical field [0001] The invention relates to a medical device, in particular to a multifunctional transfusion automatic dispensing device for transfusion. (2) Background technology [0002] In clinical medicine, intravenous infusion is a commonly used treatment method, and the mixing and dispensing of infusion is mostly manual operation, that is, manually controlling the syringe to suck and inject the drug solution. Dispensing a bottle of infusion often requires repeated operations many times. Not only are the operating procedures cumbersome and labor-intensive, but also the infusion adjustment efficiency is low, and it is easy to cause infusion contamination. And some known transfusion dispensing devices at present, such as the transfusion dispensing devices described in the utility models ZL97249467.7 and ZL 98200181.9 declared by the inventor before, still need manual control, and cannot automatically complete the dispensing process, and the work intensity of the o...

Problems solved by technology

[0002] In clinical medicine, intravenous infusion is a commonly used treatment method, and the mixing and dispensing of infusion is mostly manual operation, that is, manually controlling the syringe to suck and inject the drug solution. Dispensing a bottle of infusion often requires repeated operations many times. Not only is the operating procedure cumbersome and labor-intensive, but also the infusion adjustment efficiency is low, and it is easy to cause infusion contamination

And some known transfusion dispensing devices at present, such as the transfusion dispensing devices described in the utility models ZL97249467.7 and ZL 98200181.9 declared by the inventor before, still need manual control, and cannot automatically complete the dispensing process, and the work intensity of the operator is not reduced. Substantial mitigation; "The development and use of multifunctional dispensing machine and dispensing infusion set" (Chinese Journal of Nursing, Volume 36, No. 1, January, 2001) a kind of multifunctional dispensing machine disclosed by the article not only needs complex manual operation , such as the exchange of the ventilation tube at the positive and negative air pressure interface, the modification of the infusion set, etc., may also easily cause pollution of the infusion; there are few reports on the infusion adjustment device that can perform batch infusion adjustment
