Flow velocity controllable infusion alarm

Abstract

The invention discloses a flow velocity controllable infusion alarm which comprises a shell and a control mainboard. A clamping opening used for clamping an infusion tube is formed on the side wall of the shell; the shell is provided with an electric speed adjusting mechanism used for adjusting the speed of the infusion tube; the electric speed adjusting mechanism comprises a positioning frame arranged in the shell; the positioning frame is provided with a rotating shaft; an extrusion block which is used for extruding the infusion tube and of which the extrusion end is of an arc shape is arranged at the outer end part of the rotating shaft; and the rotating shaft is provided with an angle sensor. According to the invention, not only can the infusion speed be adjusted, but also the remaining dosage can be obtained according to the infusion speed and duration, and the use-up duration of the remaining dosage can be calculated so as to effectively avoid the situation that a patient or an accompanying person does not find the use-up in time, resulting in that a new infusion bottle cannot be replaced in time or an intravenous needle cannot be pulled out in time to cause the risks of vein blood return, infusion tube blockage or small amount of gas entering the vein blood vessel.

Description

technical field [0001] The invention relates to the technical field of infusion alarms, in particular to an infusion alarm with controllable flow rate. Background technique [0002] In clinical treatment, there are many patients who need infusion due to various diseases, and the process of infusion needs to be closely monitored during the infusion process. As a result, it often happens that the liquid in the infusion bottle has been transfused, but the patient or the accompanying staff did not find it in time, resulting in Failure to replace the new infusion bottle or pull out the venous needle in time will result in the risk of venous return of blood, blockage of the infusion tube, or a small amount of gas entering the venous blood vessel. Therefore, the infusion alarm plays an important role in clinical treatment. The existing infusion monitoring technology cannot measure the flow rate of the liquid, and cannot help nurses to control the flow rate of the pharmaceutical ind...

[0002] In clinical treatment, there are many patients who need infusion due to various diseases, and the process of infusion needs to be closely monitored during the infusion process. As a result, it often happens that the liquid in the infusion bottle has been transfused, but the patient or the accompanying staff did not find it in time, resulting in Failure to replace the new infusion bottle or pull out the venous needle in time, resulting in the risk of venous return of blood, blockage of the infusion tube, or a small amount of gas entering the venous blood vessel

Therefore, the infusion alarm plays an important role in clinical treatment. The existing infusion monitoring technology cannot measure the flow rate of the liquid, and cannot help nurses to control the flow rate of the pharmaceutical industry more intuitively, and better based on the patient's physical condition and The logistics chemical properties of the pharmaceutical industry require the adjustment of the infusion rate, which is very complicated
