Abstract: The present disclosure provides a pulmonary artery stent. The pulmonary artery stent includes: a metal stent capable of circumferential expansion; and an isolation membrane wrapping the metal stent to isolate the metal stent from an external environment, and the isolation membrane having a circumferential tensile strength less than an axial tensile strength. The embodiments of the present disclosure can not only expand the diameter of the stent according to a change in the diameter of a blood vessel to meet a support performance requirement after the blood vessel enlarges but also isolate the metal portion of the stent from a vascular environment, thus effectively solving a problem of in-stent restenosis.

Abstract: A protection circuit for lithium-ion battery is provided. The protection circuit samples the voltage of the lithium-ion battery as a sample voltage and outputs the sample voltage. A switch circuit includes a first switch having two first connection terminals and a first control terminal. The first switch connects the two connection terminals when the control terminal receives a high logic level and disconnects the two connection terminals when the control terminal receives a low logic level. One of the first connection terminals is connected to the lithium-ion battery through a first current-limiting resistor to receive a battery voltage and is connected to an output terminal of the switch circuit, the other first connection terminal is grounded. The output terminal outputs a logic low level as a turn-on signal and a logic high level as a turn-off signal of the lithium-ion battery.

Abstract: An exemplary reset circuit includes a first connection jack connected to a first power supply, a second connection jack connected to a second power supply, a reset IC, a voltage response module, and a control module. The voltage response module outputs a first response signal when the voltage provided by the second power supply is abnormal, and then the control module outputs a first voltage which is less than the voltage provided by the first power supply. The voltage response module outputs a second response signal when the voltage provided by the second power supply is normal, and then the control module outputs a second voltage which is equal to the voltage provided by the first power supply. When the voltage received by the reset IC is changed from the first voltage to the second voltage, the reset IC outputs a reset signal to reset the processing IC.
