Description

Operating room with fresh air

technical field

The utility model relates to an air supply device, in particular to a fresh air blower for an operating room.

Background technique

The operating room is a key department of the hospital, and it has extremely high requirements on the cleanliness of its indoor air. Therefore, in order to keep the operating room highly clean, it is necessary to carry out strict purification and disinfection treatment on the air flowing into the operating room. At present, the fresh air fans used in the operating room of the prior art generally use multi-stage filtration to purify and disinfect the air. In other words, different levels of filters are installed in the ventilation ducts of the fresh air fans. Different levels of filters filter out most of the dust and bacteria to meet the operating room's air cleanliness requirements. Although the air treated by the fresh air blower in the operating room with the above structure can meet the cleanliness requirements of the operating room, but because the filter only filters dust and bacteria out of the air and has no sterilizing function, it is easy to cause Bacteria breed and multiply in the ventilation duct of the fresh fan, which greatly increases the number of bacteria in the ventilation duct of the fresh fan. However, the filters have a certain filtration efficiency and cannot completely filter out the bacteria in the air, and there will still be a certain proportion Bacteria enter the operating room with the air. In other words, the more bacteria in the ventilation duct of the fresh fan, the more bacteria enter the operating room with the air. Therefore, the bacteria in the ventilation duct of the fresh fan are not only It will affect the normal use effect of the fresh air machine, and it will also increase the chance of bacterial infection of patients undergoing surgery in the operating room.

Utility model content

The technical problem to be solved by the utility model is to provide a device that can kill bacteria in the air and prevent bacteria from breeding and multiplying in the ventilation duct, so as to not only ensure the normal use effect, but also reduce the morbidity of surgery in the operating room. Fresh air fans are used in operating rooms that suffer from the risk of bacterial infection.

In order to solve the above technical problems, the utility model provides a fresh air fan for operating rooms with the following structure: it includes a ventilation pipe body with an air inlet and an air outlet. filter, medium-efficiency filter, fan, air heat exchanger, humidifier and sub-high-efficiency filter, wherein, a plasma generator is also provided in the ventilation pipe between the air inlet and the primary filter.

After adopting the above structure, the fresh air blower for operating room of the present utility model has the following advantages: since the fresh air blower for operating room of the present utility model is also equipped with a plasma generator in the ventilation pipe body between the air inlet and the primary filter, therefore, when After the air flows into the ventilation pipe from the air inlet under the action of the fan, it is ionized under the action of the plasma generator. The positive ions and negative ions generated during the ionization process will release huge energy when the neutralization reaction occurs, making the surrounding air The internal structure of the bacteria in the environment changes and the energy transfers, resulting in the death of the bacteria, which effectively solves the problem that bacteria are easy to breed and multiply in the ventilation duct of the fresh air machine, ensures the normal use of the fresh air machine, and greatly reduces the operating room. The probability of a patient undergoing surgery being infected by bacteria.

Detailed ways

The fresh air blower for the operating room of the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, in this specific embodiment, the utility model operating room fresh air machine includes a ventilation pipe body 3 provided with an air inlet 1 and an air outlet 2, and the ventilation pipe body 3 is from the air inlet 1 to the air outlet 2 The primary effect filter 4, the medium effect filter 5, the fan 6, the air heat exchanger 7, the humidifier 8 and the sub-high efficiency filter 9 are provided in sequence, and the ventilation pipe body 3 between the air inlet 1 and the primary effect filter 4 Plasma generator 10 is arranged inside, primary effect filter 4, intermediate effect filter 5, blower fan 6, air heat exchanger 7, humidifier 8, sub-high efficiency filter 9 and plasma The generator 10 is the existing conventional technology, so it will not be repeated here.

The working principle of the fresh air blower for operating room of the utility model is: under the action of the fan 6, the external air flows from the air inlet 1 into the ventilation pipe body 3, and the air is ionized under the action of the plasma generator 10, and the ionization process produces When the positive ions and negative ions in the neutralization reaction occur, they will release huge energy, which will change the internal structure of the bacteria in the surrounding environment and transfer the energy, resulting in the death of the bacteria, and then pass through the primary filter 4 and the medium filter 5 Filter out the larger dust and bacterial corpses in the air, then carry out temperature and relative humidity treatment to the air through the air heat exchanger 7 and humidifier 8, and then filter out the smaller dust and bacteria remaining in the air through the sub-high efficiency filter 9 Finally, the clean air with suitable temperature and humidity is sent into the operating room from the air outlet 2.

Claims (1)

1. A fresh fan for operating room, comprising a ventilation pipe body (3) provided with an air inlet (1) and an air outlet (2), in the ventilation pipe body (3) from the air inlet (1) to the air outlet (2) There are primary filter (4), intermediate filter (5), blower fan (6), air heat exchanger (7), humidifier (8) and sub-high efficiency filter (9) successively.
