I , Product introduction
Medical vacuum system is widely used in medical and surgical operations to provide timely and reliable attraction power
In the environment, the increasing sensitivity to pollution and the protection against infection make filtration necessary for these systems

  The necessity of vacuum system filtration has been widely popularized
Insufficient inlet filtration will damage the vacuum pump, destroy the vacuum degree, cause pollution and stop the operation of the equipment
Pollutants in the inlet pipeline include particles, dust, water vapor and other gases
Outlet emissions will also include particles, oil and harmful gases
Professional inlet and exhaust filters can effectively deal with these pollutants

Professional sterilization and filtration is dangerous for the pipeline and outlet of any vacuum system to carry a large number of bacteria
In order to protect the health of patients, medical staff, other service personnel and the general public, countries all over the world proposed to install and maintain bacterial filters many years ago
If the sterilizing filter is not installed or maintained in front of the vacuum pump, it will not only damage the vacuum pump, but also make the vacuum pump a source of bacterial pollution
The appropriate temperature and humidity of the vacuum pump is an ideal hotbed for bacterial growth
From a technical point of view, it will cause risks to the vacuum pump itself, which will lead to the replacement of the vacuum pump

  Performance requirements of vacuum sterilization filter
According to the test method of bs3928:1969, when the filtration efficiency exceeds 99
995% and the vacuum degree is 630 mbar, the differential pressure loss shall not exceed 30 mbar
  Instructions for filter replacement and handling are required
  As2896 medical gas system describes the inlet filter as follows: the medical inlet filter should be a bacterial filter, with appropriate size so that the pressure difference does not exceed 3
5kpa, and the filter element should meet ISO8573 1
Level I requirements: 0
01 & mu; M filtration efficiency

  Provisions of China gb50751-2012 technical code for medical gas engineering on sterilization filter:
5

16 filtering accuracy: 0
01-0
2μ m
The filtration efficiency is 99
995%
The sterilizing filter shall be maintained and the filter element shall be replaced in time to avoid excessive differential pressure affecting the system flow

 
  The negative pressure sterilizing filter mainly adopts a large area of sterilizing filter element with a quick installation structure, and the filtering accuracy is 0
22-mu; 0
01μ， Use 121 & there4; Regular sterilization with net steam can remove 99
995% bacteria and various bacteriophages
It is a necessary link in the medical center suction system industry, and the sterilization filter is the choice of negative pressure air sterilization
The sterilizing filter is made of 304 or 316L stainless steel shell and matched with mirror polishing to achieve no dead corner of parasitic bacteria
The filter element of sterilization filter adopts steam sterilized PTFE folding filter element
The filter element has the characteristics of high pressure resistance, high temperature, hydrophobicity and high density

II , Installation and configuration
1
  During installation, the pipes must be connected according to the air inlet and outlet label on the filter
Otherwise, the reverse installation of import and export will seriously affect the filtration effect
In order to facilitate use, replacement and maintenance, the filter shall be installed according to the standard pipeline shown in the figure below

One for standby and one for use method a filter ① Open valve A1 and A2, ② Close valve B1, B2, Z1 and Z2, and switch to filter B ① when steam sterilization is required for filter a after 3 days of use Open B1, B2, ② Close A1, A2 and ③ Open Z1 (steam valve) ④ and close Z1 20-30 minutes later
Switch AB filter in the same way and use it alternately
If the vacuum pump is overloaded, use both a and B filters ① at the same time Open valve A1, A2, B1, B2, ② Close Z1 and Z2 valves
III Characteristics of sterilizing filter
(1) the sterilizing filter is generally of cross suspension type with horizontal inlet and outlet
The multi-core filter can be designed as floor type

(2) some applications are divided into pre filter and fine filter according to actual needs

(3) air flow direction: pass through the filter element from outside to inside
Please install it according to the arrow direction on the shell label

(4) the air entering the sterilization filter must first pass through the pressure stabilizing pre filter of the air storage tank, otherwise the service life of the sterilization filter element will be affected and the expected sterilization effect will not be achieved

(5) sterilize regularly
According to the actual use, sterilize with clean saturated steam once or twice a week for 30 minutes each time
Steam temperature ＜ 121 ℃, steam pressure ＜ 0
3MPa
The valve must be opened and closed slowly
The sterilization process must be supervised by a specially assigned person

(6) after 100 times of steam sterilization or when the pressure difference of the filter element reaches 0
07-1
0mpa, a new sterilizing filter element shall be replaced

All sanitary filter cylinders are made of high-quality 304 stainless steel
Each filter is made of strict material selection and careful manufacturing
It has a streamlined design without cracks and has good surface and large corrosion resistance, so as to meet the quality standard of preventing bacterial pollution and strictly meet the requirements of GMP standard

IV Precautions for replacement of filter element (old filter element is infectious waste, with high risk)
（1）  The filter element is a consumable
In order to ensure the filtering effect, please replace it every 3-6 months
　
(2) Please replace the filter element according to the professional personnel in the platoon, do personal protection work, wear goggles, masks and protective clothing (refer to gb11651 code for selection of personal protective equipment)
It is recommended to sterilize the filter with steam before replacement
If there is no steam, 75% ethanol can be injected into the filter and kept sterilized for half an hour

(3) Irrelevant personnel are strictly prohibited from entering the site during replacement
After replacement, infectious sources may run out of the pipeline
Ultraviolet and other methods are needed to disinfect the pump room space, and personnel are strictly prohibited from entering for a period of time

（4）  The old filter element shall be treated innocuously according to the relevant disposal requirements of infectious pollutants
It is strictly prohibited to throw it away at will
