Dripping bucket with transfusion automatically stopped

Abstract

The invention discloses a dripping bucket with transfusion automatically stopped. The dripping bucket with transfusion automatically stopped comprises a chamber and a floating core arranged in the chamber, wherein a base is arranged on the bottom of the chamber, and an outer side surface of the base and an inner side surface of the chamber are in seal fit. The base is provided with a liquid outlet, a fluid channel and a seal fit part arranged around the liquid outlet; and the floating core and the seal fit part are in seal fit. The fluid channel is provided with a first end opening and a second end opening; the first end opening is directly communicated with the chamber, and is close to a side wall of the chamber; the second end opening is formed in a surface of the seal fit part, and faces the floating core; and when the chamber is squeezed, an air flow or a liquid flow which is discharged out of the second end opening can push the floating core to move upwards, so that the floating core and the seal fit part are unsealed. By means of the dripping bucket with transfusion automatically stopped, every time transfusion begins and a liquid medicine flows into the dripping bucket, thefloating core can normally float so that transfusion can be conducted normally.

Description

Technical field [0001] The invention relates to a medical infusion device. Background technique [0002] In order to reduce the workload of the medical staff and prevent the blood from returning after the infusion is completed, the drip bucket with the function of automatically stopping the infusion has been more and more widely used. Most of the existing automatic liquid drip stoppers are equipped with a floating core inside the chamber of the drip bucket, and the floating core closes the liquid outlet of the drip bucket in the initial state. When the liquid medicine flows into the chamber, the floating core will float on the liquid surface, thereby opening the liquid outlet to realize the infusion; and when the liquid medicine in the chamber is finished, the floating core will automatically fall under the action of gravity, thus Close the liquid outlet of the drip chamber. [0003] During the continuous infusion process of the automatic dripping hopper, the floating core seals ...

AI Technical Summary

Problems solved by technology

However, when the liquid medicine in the dripping funnel is finished dripping, a certain negative pressure will be generated under the floating core. Due to the adsorption effect of the negative pressure on the floating core, sometimes it will cause the next infusion to start and the liquid medicine will flow into the dripping funnel When the liquid outlet has not been opened, and thus can not achieve normal infusion
