Dripping bucket for blood transfusion device

Abstract

The invention relates to a dripping bucket for a blood transfusion device. The dripping bucket for the blood transfusion device comprises a dripping bucket body, wherein a dripping bucket cap is fixedly arranged on the upper part of the dripping bucket body, a filter is arranged on a liquid outlet which is formed in the bottom of the dripping bucket body, and the filter comprises a cylindrical bracket; the outer wall of the cylindrical bracket is closely connected with the inner wall of the dripping bucket body, a filter screen is arranged, and the bottom of the filter screen is fixedly connected to the inner wall of the cylindrical bracket; and the top of the filter screen is sealed, and a limiting mechanism for limiting upward movement of the cylindrical bracket is arranged at the lowerpart of the interior of the dripping bucket body. The dripping bucket has the advantages of a simple structure and convenient manufacture, materials are saved through the novel design of the filter screen, and no easy blocking occurs through adoption of a ceiling mounting method during use, so that the speed of blood transfusion treatment is ensured; and the filter screen is embedded in the dripping bucket, and risks of liquid leakage are avoided, so that the occupational exposure risks of the medical staff are reduced, contradiction between doctors and patients is alleviated, and the degree of satisfaction of the patients is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a dripping bucket for a blood transfusion set. Background technique [0002] At present, there are generally two ways to combine the dripping funnel and the filter screen in clinical use. One is to directly heat-bond the liquid outlet at the lower end of the dripping funnel. The fusion of the heat-sealing surface is poor, so there will often be leakage at the junction of the two heat-sealing surfaces, and blood leakage will pollute the medical environment, increase the chance of medical staff contacting blood, and increase the occupational exposure risk of medical staff; the second is to use a full-stent filter to place Inside the drip funnel, the full-stent filter is large in size and high in cost, and there is a risk of blood clots clogging at the bottom of the filter after long-term blood transfusion, which will affect the speed of blood transfusion and increase the risk of pa...
