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.

The medical purifier is mainly equipped with specially designed high radiation intensity C-band ultraviolet light and photocatalyst to illuminate the flowing air and catalyze the photocatalyst. Various bacteria and viruses in the gas, such as Escherichia coli, Staphylococcus aureus, coronavirus, influenza virus, etc., are effectively killed; As well as other pathogens, the DNA structure in their cells will be destroyed after a certain dose of irradiation, so as to kill bacteria and viruses in the gas without using any chemical substances

Whether it is an air purifier or an air purification sterilizer, most of them use a filter (filter screen) to purify the air, and the air purification sterilizer has the functions of both air purification and air disinfection, so the filter is also an extremely important core device of the air purification sterilizer. Some consumers know too little about filters, or do not know what their functions are, let alone the problem that filters need to be replaced regularly. Most filters (filters) need to be replaced regularly, especially HEPA (high-efficiency filtration) filters (filters), which are the mainstream configuration of medium and high grade air purification disinfectors and air purifiers. At present, the service life of the filter (filter screen) on the market is generally between 3-9 months, which will vary according to the service time. If the filter (filter screen) is used less frequently, the period will be longer, otherwise it will be shorter. But there is no doubt that the filter (filter screen) must be replaced regularly when reaching a certain time period, otherwise it will be longer, Not only does it fail to achieve the effect of air purification and air disinfection, but it is also likely to cause "secondary pollution". Fortunately, the mainstream air purification disinfectors on the market now show the replacement time of the filter (filter screen), and these matters are generally explained in the product manual, so the product manual still suggests that consumers read it carefully.
