The invention discloses an infusion automatic monitoring device capable of monitoring the flow rate of liquid medicine and reliably stopping flow, which comprises a monitoring device and a liquid medicine control device. The back of the monitoring device of the infusion automatic monitoring device is connected with a microprocessor; the microprocessor is also connected with a signal circuit for transmitting out a signal, the liquid medicine control device and a setting module; the monitoring device is a photoelectric detector; a connecting line of a light emitting tube and a light receiving tube of the photoelectric detector is positioned above the liquid level in an infusion drip chamber; and the liquid medicine control device consists of a stepping motor, a driving gear, a rack, a guide rail and a fixed plate. The infusion automatic monitoring device is arranged at a terminal of a hospital bed, can be switched into a system used in a hospital currently in a matching manner and also can be matched with other various switchboards in the market. The infusion automatic monitoring device is small in size and light in weight, is convenient to use in a suspending manner, is low in cost, is reliable to control and is convenient and simple to operate; the microprocessor can be preset or set on site to adapt to various conditions; and the infusion automatic monitoring device not only can be used for monitoring whether liquid medicine exists in an infusion tube, but also can be used for monitoring the flow rate of the liquid medicine, abnormity is more convenient to find and the flow can be reliably stopped.
Description
technical field [0001] The invention relates to automatic monitoring, in particular to an automatic monitoring instrument in the medical industry, and more specifically to an automatic infusion monitoring device capable of monitoring the flow rate of medicinal liquid and reliably shutting off the liquid during infusion treatment for patients. Background technique [0002] In the process of infusion therapy for patients, it is very necessary to monitor the infusion. Some of the devices for monitoring infusion in the prior art use motors, which have problems such as high noise, high power consumption, and complicated product structure. There are also devices that can only detect flow breaks, but cannot cause changes in flow velocity due to abnormal conditions. Contents of the invention [0003] The object of the present invention is to provide an automatic transfusion monitoring device capable of monitoring the flow rate of medicinal liquid and reliably shutting off the...
