The invention discloses an automatic infusion pager which comprises a starting triggering device, an alarm and a control device. The starting triggering device comprises rubber soft supports which are symmetrically arranged in a dropping device and are provided with conductive electrodes, and a hollow metal ball. The control device comprises the rubber soft supports, a resistor I, the alarm and a field-effect transistor which are sequentially in series connection. The starting triggering device is used for detecting whether liquid medicine enables the control device to be connected to control the alarm or not. Under a non-liquid-medicine state, the hollow metal ball descends to be in conductive connection with the two rubber soft supports, the grid electrode of the field-effect transistor loads voltages to enable a source electrode and a drain electrode to be connected, and the alarm is connected and transmits alarm signals. According to the automatic infusion pager, floating of the metal ball is used for controlling disconnecting and connecting of the source electrode and the drain electrode of the field-effect transistor, namely the field-effect transistor is used as an electric control switch, connecting and disconnecting of a circuit are more accurate, automatic calling of products is more reliable, the production cost is low, the caring burden of a patient and the relatives of the patient is lightened, and the service quality of a hospital is improved.
Description
technical field [0001] The invention relates to a medical transfusion device, in particular to an automatic transfusion caller. Background technique [0002] At present, when the traditional medical infusion bottle or infusion bag is about to finish the infusion, the nurse must replace the new infusion or remove the needle in time to prevent air from entering the blood vessel. Family members or nurses come to accompany the infusion, which is labor-intensive and time-consuming. Contents of the invention [0003] In order to solve this problem in the above-mentioned technologies, the present invention provides an automatic infusion caller, which uses a metal ball to float in the liquid medicine to control the field effect tube. The voltage is applied so that the calling device is switched on to achieve automatic calling. [0004] In order to solve the deficiencies of the above-mentioned technical problems, the technical solution adopted by the present invention is: an auto...
