How often should HEPA filters be replaced in the operating room? Renhe and purification pointed out that according to the number of particles with a particle size greater than or equal to the number of dust particles in the air after cleaning, the purification laminar flow operating room can be divided into 100,000

HEPA filter replacement cycle in the operating room.

After a certain period of use in the operating room, there will be different degrees of pollution, in addition to daily maintenance, it should also be regularly monitored according to the relevant regulations to ensure that the cleanliness of the operating room is qualified, so as to ensure that the prepared preparations are qualified.

preparation of the operating room; Determination of the minimum number and location of sampling points; Suspended particle number test; sedimentation count test; sampling methods; Cultivate; The comprehensive index of colony counting BCJ-1D laser dust particle counter meets the national standard ( ) minimum test particle size o, m, air sampling instrument self-cleaning o, m file total count for 3 consecutive times (1min times) is zero, the time required is less than 10 min, the counting of any channel can be observed in real time, the internal pollution sources in the operating room are mainly people, items, equipment and other people are the largest pollution sources, accounting for about 90%, and the filtration method has a high capture rate. Economical and widely used, the particles in the air or most of the particles can be filtered out, therefore, the normal operating room is almost sterile or in line with the standard, the laser dust particle counter is mostly used for monitoring, the replacement cycle of the high-efficiency air filter is generally 1-2 years, the replacement cycle of the primary filter should be shorter, and the replacement cycle of the high-efficiency air filter is not fixed, it should be based on the air quality, frequency and time of use, and the monitoring results, and should be replaced when the test results are close to the test standard. It is necessary not only to ensure that the cleanliness of the operating room is qualified, but also to avoid unnecessary waste.

After the clean operating room is thoroughly filtered by the purified air system, the sampling and culture of the natural sedimentation method are in line with the requirements of first-class air purification, which provides a safety guarantee for the operation. After the purification of the clean operating room, it can only reduce or eliminate the bacteria in the air, and cannot have the effect of adsorbing dust on the surface of the clothing and sterilizing it. Therefore, it is particularly important to strictly manage the hygiene of the clean operating room, implement air purification, and regular care, maintain the clean indoor area, control the source of pollution, and reduce bacterial infection.

In short, the management of clean operating rooms is very important, and effective, scientific and strict management plays a key role in ensuring medical quality and controlling infection.

Legal analysis: 1. The floor of the surgical pin trouser room and all kinds of items used should be kept clean and tidy frequently, and the windowsill, floor, shadowless lamp, dressing table, tray, infusion stand, operating table and corridor floor of the operating room should be wiped with a clean wet rag every day before surgery. 2. Immediately after each operation, the dirt on the ground should be washed off, and the threads, paper scraps and other debris on the ground should be removed.

After contamination surgery, indoor items and floors should be thoroughly cleaned and disinfected. 3. Thoroughly clean the floor, walls, and indoor materials of the surgical room on a regular basis every month.

Legal basis: Hospital Environmental Sanitation Management》 Article 1 The hospital advocates cleanliness, hygiene, and social morality, and all hospital employees should consciously maintain the hospital environment and indoor hygiene.

How often should HEPA filters be replaced in the operating room? Renhe and purification pointed out that according to the number of particles with a particle size greater than or equal to the number of dust particles in the air after cleaning, the purification laminar flow operating room can be divided into four levels: 100,000, 10,000, 1,000 and 100. Among them, the higher the number, the lower the level of purification.

Coarse inefficient filters.

The resistance has exceeded the rated initial resistance by 60pa, or equal to 2 design or operation initial resistance.

3-6 months, replace at any time if it exceeds the standard.

Intermediate filter.

The resistance has exceeded the rated initial resistance by 80pa, or equal to 2 design or operation initial resistance.

6-12 months, replace at any time beyond the standard.

Sub-high efficiency filter.

The resistance has exceeded the rated initial resistance by 100pa, or equal to 2 design or operation initial resistance (3 times when low resistance is sub-efficient).

More than 1 year, it can be replaced at any time if it exceeds the standard.

High-efficiency filters.

The resistance has exceeded the rated initial resistance of 160pa, or equal to 2 design or operation initial resistance.

More than 3 years, replace at any time if it exceeds the standard.

In the hospital, many surgeries require aseptic operation, and if you want to truly achieve aseptic operation, you can't do without the special high-efficiency filter in the operating room, but the high-efficiency filter in the operating room requires that it be replaced once every 2 or 3 years.

The above is "How often should the HEPA filter be replaced in the operating room?" If you have any questions, you can consult Anhui people and purification.

The particularity of the operating room, generally in the middle and middle of the normal replacement of the effect, it is recommended not more than two years, if the frequency of use is high, it is recommended to shorten the time, after all, the efficient and good operation in the operating room will reduce the surgical infection a lot! There is also the particularity of the operating room, which is generally recommended to be replaced in stages, because the load of the general operating room is relatively large, there are more surgeries, and once a special situation occurs, it must be opened immediately.

The installation of high-efficiency filters in the operating room of Shenzhen Minghao purification medical industry should meet the following requirements:

1. Before the installation of the high-efficiency filter, it is not allowed to tear or open the packaging bag or packaging film by hand; The air filter should be stored in strict accordance with the direction marked on the high-efficiency filter packaging box; In the process of handling the high-efficiency filter, it should be handled and handled gently to avoid violent vibration and collision.

2. The high-efficiency air filter in the operating room should be installed immediately after passing the visual inspection; When the corrugated plate combination filter is installed vertically, the corrugated plate must be perpendicular to the ground; The connection between the vertical and the frame of the filter is strictly forbidden to leak, deform, damage and leakage. The frame for installing the high-efficiency filter should be flat and clean, and the flatness deviation of the installation frame of each high-efficiency air filter and the non-partition filter shall not exceed 1 2mm; After installation, the inner wall must be kept clean and free of floating dust, oil, rust and sundries.

3. The installation direction of the air filter must be correct, and the surrounding area and interface of the filter should be tight and leaky after installation;

4. When the high-efficiency filter adopts a mechanical seal, it should be sealed with an airtight gasket; After installation, the compression of the bedding should be uniform, and after installation, a scan should be carried out for leak detection. Pack.

With the improvement of the modernization of hospital buildings, the clean room of the hospital is developing from a clean operating room to a clean operating department. The "Technical Code for the Construction of Hospital Clean Operating Department" GB50333-2002 issued by the Ministry of Construction of the People's Republic of China clearly stipulates the main technical indicators such as cleanliness, temperature and humidity, air supply volume and fresh air volume of the clean operating department room in China, which puts forward strict requirements for the design of the purification air conditioning system of the hospital operating department.

Therefore, the location of the installation of the high-efficiency filter in the clean operating room has also changed, unlike other high-efficiency filters in the clean room installed in the ordinary high-efficiency air supply outlet, the clean operating room must use clean laminar flow air supply.

Laminar flow ceiling is the end of the purified air supply in clean operating rooms and laminar flow wards, and it has both high-efficiency filter, flow sharing and airflow compensation. The rationality of the laminar flow ceiling structure directly affects the air supply effect and purification level of the operating room. Vertical air supply mode, stainless steel laminar flow air supply ceiling for the operating room:

Laminar flow air supply ceiling is developed with reference to international and domestic specifications and technologies, after more than 10 years of experience in actual hospital use, the structure is advanced and reasonable, divided into I, II, III operating rooms, box cold plate spraying, the lower frame is all stainless steel, beautiful and durable. The clean air supply ceiling device is based on the leading leakage barrier layer technology at home and abroad, and the use of this equipment can reasonably distribute the air flow in the clean room and effectively ensure the cleanliness of the room (100 grade of air supply surface).

Laminar air supply ceiling adopts air cleaning technology to control microbial pollution to different degrees, so as to control the air cleanliness of the space environment and adapt to the requirements of various surgeries; and provide the right temperature and humidity to create a clean and comfortable operating space environment. It can be widely used in hospital clean operating rooms, clean wards, clean animal rooms, etc.

Thank you for the above satisfaction.
