Abstract

The invention discloses an infusion apparatus capable of stopping infusion automatically. The infusion apparatus comprises a dropper with an input port and an output port, the inner wall of the dropper is fixedly connected with an infusion stopping device, a cavity is formed in the infusion stopping device, with the upper end closed and the opening directing towards the output end of the dropper, a floating ball is arranged in the cavity, and the lower end of the cavity in the infusion stopping device is in a funnel shape. The intervals between the outer wall of the infusion stopping device and the inner wall of the dropper form a first passage and a second passage, the first passage is arranged opposite to the second passage, a liquid inlet hole is formed in the outer wall surface of the infusion stopping device opposite to the second passage, and the liquid inlet hole penetrates the cavity. According to the infusion apparatus, the floating ball insulates air against entering the infusion tube connected with the output end of the dropper after the liquid is dropped over, a certain amount of liquid always exists in the first passage and the second passage and liquid levels are the same, which play a role in sealing the cavity; the cavity pressure increases to form negative pressure, and back flow of the liquid ceases when the pressure of the back flow of the liquid is balanced with the negative pressure, which have a real impact of anti-backflow of blood.

Description

technical field [0001] The invention relates to the technology of a medical intravenous injection infusion set, in particular to an automatic hemostasis infusion set capable of preventing blood return. Background technique [0002] In the course of clinical treatment, many patients often need to carry out transfusion, so as to cure the disease by the therapeutic means of transfusion. Thereby, need a large amount of use infusion sets. Present infusion sets are basically disposable infusion sets, which are used to establish disposable consumables for passage between veins and medicinal liquids, and have played a beneficial role in preventing cross-infection between patients. However, using these disposable infusion sets has relatively There are many problems, and the labor intensity of the medical staff is very high. Usually, one medical staff has to take care of the infusion of patients in multiple wards. It often happens that the medical staff, patients or family members of...
