Vehicular child safety monitor and program control method implemented by same

The invention aims to design a monitor for guaranteeing the safety of children in an automobile and a program control method implemented by the monitor. The monitor is divided into a host and a slave. The host is arranged at the front end of a driver, the slave is bound on a backrest of a seat at the front of child seats, and information can be exchanged between the host and the slave via SPI (serial peripheral interface) bus. A camera is arranged on the slave, and images of the seats of a back row can be acquired by the camera in real time in automobile operation procedures and are displayed on a liquid crystal display of the host, so that the driver can assuredly conveniently observe conditions of the children on the back row without turning around. Liquid crystal display functions can be inactivated after the automobile is switched off, human body detecting sensors and environment detecting sensors can be started by the monitor, prompting information can be transmitted to preset mobile phone numbers by the monitor via a GSM (global system for mobile communications) module if the children who linger in the automobile are detected and interior environments of the automobile are unfavorable for human health, and the children also can make calls to the mobile phone numbers via a distress call key.

Infusion weighing monitoring method and system

ActiveCN104707214ACalculating remaining time of infusionAccurate time monitoringIntravenous devicesFlow controlBottlePediatrics
The invention provides an infusion weighing monitoring method. The infusion weighing monitoring method comprises the steps that firstly, an initial weight A of an infusion bottle device placed on the ground is obtained through weighing; secondly, after a set drop number of liquid medicine dripped from a drip chamber of the infusion bottle device, a weight B of the infusion bottle device placed on the ground is obtained through weighing; thirdly, the weight difference value between the initial weight A and the weight B is divided by the set drop number, and then the weight of each drop of liquid medicine is obtained; fourthly, the total weight of infusion medicine is divided by the weight of each drop of liquid medicine in order to achieve the total drop number of the infusion operation; fifthly, the set drop number of the drip chamber is subtracted from the total drop number, so a residual drop number of the infusion operation is obtained; sixthly, the residual drop number of the infusion operation is divided by the current dripping speed, so an infusion residual time is obtained. By the adoption of the infusion weighing monitoring method, the weight of each drop of liquid medicine can be obtained through weighing, and therefore the infusion residual time can be worked out; the weight of each drop of liquid medicine is corrected continuously in order to update the infusion residual time, so time monitoring is more accurate; a nurse can be reminded ahead of time sufficiently.
