The invention provides an infant state monitoring system. The infant state monitoring system comprises a microwave Doppler sensor, a filter amplifier module, a control module, an abnormity judging module, a communication module and an alarm, wherein the microwave Doppler sensor is used for emitting a microwave signal to an infant, and receiving a feedback signal of the infant; the filter amplifiermodule is used for carrying out noise filtering and signal amplification on the feedback signal; the control module is used for obtaining the heart rate and respiration rate of the infant through thecalculation for the amplitude and phase position of the feedback signal; the abnormity judging module is used for setting a detection time period, and acquiring the real-time heart rate and respiration rate, when the heartbeat or respiration of the infant within the detection time period rises or falls continuously, an abnormity alarming signal is sent out; the communication module is used for providing a wired LAN interface or a wireless communication module; the alarm is used for receiving the abnormity alarming signal sent by the abnormity judging module. With the infant state monitoring system, the respiration and heartbeat are measured under the condition that the infant is not contacted, alarming is given when the respiration and heartbeat change, therefore, the safety of the infantis guaranteed, and the working strength and mental stress of nursing staff are also alleviated.

The invention discloses a piston and pneumatic type 3D printing biological material extrusion test device. The piston and pneumatic type 3D printing biological material extrusion test device comprisesa box, a piston component, a mixing component, a pushing component and an air pressure component and is characterized in that a temperature-adjustable extrusion test environment is formed in the box;the piston component comprises a cylinder, a piston and a piston rod, one end of the cylinder is provided with a needle, guide channels communicated with the cylinder are arranged in the piston rod and the piston, materials mixed by the mixing component flow into the cylinder, materials in the cylinder are extruded by the piston rod pushed by the pushing component, and the materials in the cylinder can also be extruded by feeding air flow into the guide channels; various data is collected through a displacement sensor and a pressure sensor during the material extrusion, and the materials arereceived by a receiving plate and weighed by an electronic scale. By the structure, the test device has the advantages that high precision is achieved, test efficiency is increased, the labor intensity of test staff is lowered, the extrusion curve of the test materials can be measured in real time, and data and guidance can be provided for actual production and design.
