Problems solved by technology

Sometimes due to untimely inspection, especially during infusion late at night, escorts, nurses or patients are prone to doze off. The pressure in the tube is balanced, and the infusion will stop automatically. At this time, the liquid level in the infusion set is below the drip pot on the infusion set, and blood return often occurs
When replacing the liquid, the air under the drip pot needs to be exhausted before the infusion, which brings unnecessary troubles to the infusion

Abstract

The invention discloses a warning device during transfusion. A user can be timely reminded of liquid replacing or pulling of a transfusion needle. The warning device comprises a spring. The upper end of the spring is connected with a pulling ring which is connected to the lower end of the spring. A scale ruler arranged on the right side of the spring is connected to a connecting rod between the spring and the pulling ring. A scale hole is formed in the scale ruler. A scale plug is inserted into the scale hole. The scale plug is in a reversed-L shape. A static contact is connected to the lower end of the scale plug in an insulation mode. The left end of the horizontal rod is connected to the connecting rod between the pulling ring and the spring. A moving contact is connected to the right end of the horizontal rod in an insulation mode. The moving contact and the static contact are arranged oppositely. The moving contact and the static contact are electrically connected with the warning device. When liquid in a bottle is used up by transfusion, the moving contact and the static contact are in contact, the warning device or a calling device is communicated, and a company or a nurse or a patient can be reminded of liquid replacing or pulling of the transfusion needle in time.

Description

technical field [0001] The invention relates to an alarm device, in particular to an alarm device for transfusion. Background technique [0002] When the patient is infusion, he needs to accompany, nurse or patient himself often check how much liquid there is in the infusion bottle, and decide whether to change the liquid or pull out the infusion needle according to the amount of liquid. Sometimes due to untimely inspection, especially during infusion late at night, escorts, nurses or patients are prone to doze off. The pressure in the tube is balanced, and the infusion will stop automatically. At this time, the liquid level in the infusion set is below the drip pot on the infusion set, and blood return often occurs. When changing the liquid, the air under the drip pot needs to be exhausted before the infusion, which brings unnecessary troubles to the infusion. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide...
