In order to achieve the above object, the utility model provides a following technical scheme:
an emergency department transfusion liquid level alarm device comprises a transmission part, a liquid medicine bag and a detection and alarm part, wherein the transmission part comprises a fixed pulley and a movable pulley, the fixed pulley is fixed on the roof of a sick house, a rope bypasses a groove section of the fixed pulley and is bound with an upper fixed hook of the movable pulley, and the other end of the rope bypasses the movable pulley and extends out to be connected with the detection and alarm part; the detection and alarm part comprises a spring dynamometer, a conductor, a normally open contact, a power supply and an alarm, and the detection and alarm part is arranged at the head of a sickbed.
Further, the liquid medicine bag is hung on a fixed hook below the movable pulley.
Further, one end of the spring dynamometer is connected with the rope extending out of the transmission part.
Furthermore, the normally open contact, the power supply and the alarm are connected through leads.
Furthermore, the alarm and the power supply adopt a DC-5V power supply.
Compared with the prior art, the beneficial effects of the utility model are that:
1. adopt newton's dynamometer and assembly pulley to realize the infusion and finish the autoalarm, do not carry out real-time automatic monitoring to patient's infusion condition, can realize the autoalarm according to the scale of different kinds of different quality infusion bottle accessible adjustment electric bell on newton's dynamometer normally open contact and alignment newton's dynamometer moreover.
2. The whole device can be installed and fixed on the mobile device, can be freely moved, and is convenient and fast. The whole device structure adopts the modularized and systematic design, not only can realize the quality of liquid in the bottle of the real-time infusion bottle, but also can alarm in time to avoid the condition of blood backflow, and has low manufacturing cost, simple structure and easy processing, production and manufacture.
