Abstract

The invention discloses an infusion device which comprises an infusion drip tube, a light blocking floater, a luminous tube lens and a light sensing tube lens. The light blocking floater is positionedin the infusion drip tube, a luminous tube is arranged on one side of the infusion drip tube via the luminous tube lens, a light sensing tube is arranged on the other side of the infusion drip tube via the light sensing tube lens, a valve is connected with a liquid outlet of the infusion drip tube, an infusion channel is arranged in the valve, an iron core is arranged in the infusion channel, a silica gel layer is coated outside the iron core, an adhesion layer is arranged on the outer side of the valve, and the valve clings onto an electromagnet. Compared with the prior art, the infusion device has the advantages that infusion states can be monitored by means of light sensing, infusion can be automatically shut down when completed, accordingly, backflow and air inflow can be prevented, safety accidents due to negligence can be prevented, and the infusion device is convenient to use and has popularization and application value.

Description

technical field [0001] The invention relates to a medical device, in particular to a transfusion device. Background technique [0002] Infusion is also known as drip or hanging water. It is a large dose (more than 100ml for one administration) injection that is infused into the body by intravenous infusion. Usually packaged in glass or plastic infusion bottles or pouches without preservatives or bacteriostats. When in use, the drip rate is adjusted through the infusion set, and it enters the vein continuously and steadily to replenish body fluids, electrolytes or provide nutrients. In the prior art, the guardian needs to monitor the state of the infusion all the time during the infusion process. When the infusion is not detected in time, the blood will flow back or enter the air, resulting in danger. Therefore, there is room for improvement. Contents of the invention [0003] The object of the present invention is to provide an infusion device in order to solve the abov...
