A safety transfusion device with an alarm

Abstract

The invention discloses a safe infusion device with an alarm, and belongs to the field of infusion devices. The safe infusion device comprises a vertical rod, a base is fixedly connected to the lowerend of the vertical rod, a host computer and a buzzer are fixedly connected to the vertical rod, the host computer and the buzzer are electrically connected, pressure regulating buttons and a single-chip microcomputer are installed on the host computer, and the pressure regulating buttons and the single-chip microcomputer are all electrically connected to the host computer. Through the safe infusion device with the alarm, infusion canisters can be uniform in specification, and the alarm precision is improved; meanwhile, when an infusion canister moves upwards, a speed governing frame is drivenby the infusion canister to move upwards, the infusion flow velocity of an infusion tube is reduced under the effect of a speed governing plate, an infusion flow velocity increase caused by infusioncanister rise is effectively offset, and thus the infusion flow velocity is stabilized; a pressure regulating device is controlled through the buttons on the host computer when a nurse regulates the speed before infusion, accordingly the attractive force of an electromagnet is controlled, infusion flow velocity regulation is facilitated, the infusion speed is stable, untoward effects are effectively avoided, a body is prevented from being damaged, and the infusion is safe.

Description

technical field [0001] The invention relates to the field of infusion devices, more specifically, to a safety infusion device with an alarm. Background technique [0002] Existing infusion devices usually require real-time observation by the patient himself or the nursing staff in order to facilitate the timely replacement of the liquid medicine bag or end the infusion. Because the infusion process often takes a long time, the patient or the nursing staff may not find out that the liquid medicine has been infused in time due to fatigue, which leads to the inability to replace the liquid medicine bag in time to continue the infusion or pull out the needle to end the infusion process, which is easy to cause For medical accidents, the existing alarm methods mostly use the gravity method to alarm to avoid the above situation. However, due to the different quality of the bottles of different liquid medicine bottles, the alarm time is different, the alarm is not accurate enough, a...
