Automatic stop device for intravenous drip infusion

Abstract

The invention provides an automatic stop device for intravenous drip infusion. The automatic stop device comprises a drip kettle, wherein the upper end and the lower end of the drip kettle both are connected with infusion tubes; a monitoring box is arranged outside the drip kettle; a mounting hole is formed in the monitoring box in a penetrating manner from top to bottom; the monitoring box sleeves the outer side of the drip kettle through the mounting hole; a photosensitive plate is arranged on a left side wall of the mounting hole; a light sensor is arranged at one side of the photosensitiveplate in the monitoring box; a main core board is arranged at the left side in the monitoring box; an infrared spotlight is arranged at the lower part of the right side of the mounting hole; a storage battery is arranged at the right side in the monitoring box; a stop box is suspended below the monitoring box through slide fasteners at two sides; and a stop assembly is arranged in the stop box. According to the automatic stop device, a principle that light is refracted in a liquid is utilized, and light refraction is generated when an infrared ray passes through a drip liquid, so that the automatic stop device achieves real-time monitoring of liquid level reduction when infusion of the drip liquid is completed and timely stops infusion, and the problems that medical personnel need to manually stop infusion and the infusion situation needs to be manually monitored in real time during existing intravenous drip infusion are solved.

Description

technical field [0001] The invention belongs to the technical field of infusion equipment in medical injection department, and in particular relates to an automatic stop device for drip infusion. Background technique [0002] The traditional drip infusion device includes an infusion tube inserted and connected to a drip bottle, and an injection needle is connected to the end of the infusion tube to pierce the human skin to the blood vessel to transmit the drip, and a drip pot is provided near the upper end of the drip infusion. The medicinal solution for drainage in the drip bottle is first stored and buffered, and then transmitted downwards. A manual switch is set in the middle of the infusion tube to control the flow through a gear. The infusion tube urgently stops the circulation of the medicinal liquid. When using this infusion device to infuse the patient, the family members or nurses must accompany and monitor and take care of it. The air above the bottle will enter t...
