The working principle of the medical pager is the called user receiver in the wireless paging system. It consists of superheterodyne receiver, decoder, control and display. It selects the useful signal to be received from the paging signal and interference transmitted by the base station, restores it to the baseband signal of the original paging machine, and generates audio (or vibration) and digital (or letter, Chinese character) messages. The BP machine has two modes of manual tandem and automatic tandem, and the corresponding paging stations are called manual paging stations and automatic paging stations. The manual paging station needs manual operation to encode these information and send signals through the transmitter. According to the line number of the incoming phone, the automatic paging station automatically finds out the caller's phone number and sends it out at the same time, so that the callee can know which phone is calling. Pagers often used are divided into two categories: digital pagers and Chinese pagers. Digital pager is small, cheap and practical. The Chinese pager displays Chinese characters directly, and the information is easy to recognize.

Briefly describe the maintenance of medical air purifier: 1. Unplug the power plug before cleaning and maintenance. Use warm water or neutral detergent when cleaning. 2. Air inlet prefilter: clean it every 6 months, and clean it every 3 months if it is seriously polluted. After unloading, rinse with clean water, cool and dry before loading. Keep records. 3. The internal electric field components are generally maintained once every two years, and once a year in case of serious pollution, which is carried out by the relevant departments and recorded. 4. Maintenance of composite activated carbon filter: the wall mounted non activated carbon filter does not need to be replaced.

Negative ions are called "air vitamins". They can improve air quality, purify air, and have a very important impact on the human body. Breathing an appropriate amount of negative ions every day can strengthen the function of cerebral cortex and mental activity, as well as reduce blood pressure, enhance the function of the heart and increase the function of the lungs. Therefore, negative ions are widely used in household appliances as air purifiers.

At the same time, the intelligent flow statistical monitoring system can timely monitor the gas concentration, gas pressure, gas purity, etc. at each gas consumption point, and can timely find out the location with large local gas flow in case of gas leakage, and prompt users to deal with it in a timely manner through audible and visual alarms. The intelligent medical and nursing management communication system embodies the design concept of "people-oriented". Centering on medicine, nursing and patients, it breaks through the traditional call concept and is a digital hospital solution for intelligent ward call and clinical information management systems. It covers all aspects of the construction of digital wards, supports medical pagers, nursing signs, information release, card reading positioning, WEB statistical query, and access control system, and realizes seamless connection with hospital information management system (HIS). It is of great significance to strengthen ward management, reduce work intensity, improve nursing quality, improve ward security, and increase patient satisfaction. Its main terminals include multimedia extensions and handles.
