Variable air volume and variable grade air feeding device of clean operation room

Abstract

The invention discloses a variable air volume and variable grade air feeding device of a clean operation room. The device comprises air feed boxes, an air feed pipe connected with box bodies, a static pressure box connected with the air feed pipe, and an air processing mechanism connected with the static pressure box. The air feed boxes further comprise a first air feed box, a second air feed box and a third air feed box which are distributed in parallel, and the bottom of the first air feed box, the bottom of the second air feed box and the bottom of the third air feed box are respectively provided with an air feed face. The air feed pipe is provided with a first air feed pipe, a second air feed pipe and a third air feed pipe which correspond to the air feed boxes. The first air feed pipe, the second air feed pipe and the third air feed pipe are respectively provided with a constant air volume device, and the first air pipe and the third air pipe are respectively provided with an opening-closing device. Three independent air feed boxes are used, so the air feed area can be changed so as to change air feed amount, to keep the air speed on a section unchanged and to maintain air flow characteristics of plug flow. Therefore, energy consumption is reduced, and the use range of the operation room is widened.

Description

technical field [0001] The invention relates to the field of air supply systems for operating rooms, in particular to an air supply device with variable air volume and levels for clean operating rooms. Background technique [0002] The clean operating room is in accordance with the requirements of my country's national standard "Building Technical Specifications for Clean Operating Departments of Hospitals" GB50333. The clean operating room should be equipped with air supply devices with different air supply areas in the indoor center according to different levels of requirements to ensure the cleanliness and sterility of the surgical site. Require. The "Hospital Clean Operation Department Building Technical Specifications" GB50333 stipulates different levels of clean operating rooms and applicable operations, or in other words, different types of operations should be performed in different levels of operating rooms. [0003] Clean operating room level and applicable operati...

AI Technical Summary

Problems solved by technology

[0005] Because clean operating rooms, especially Class I special clean operating rooms, have a large area, good facilities, high cost, and high operating costs, and there are not many high-risk operations such as joint replacement and organ transplantation, the use of Class I special clean operating rooms Less rate, more free time

However, general surgical operations are carried out in Class III general clean operating rooms. The number of operations is full every day, and the operating rooms are not enough. If patients need general surgery, they can only queue up. Sometimes the waiting time is too long and the condition is delayed.

In the same situation, due to medical needs, Class II standard clean operating rooms have to be set up in the outpatient and emergency departments of hospitals, but the utilization rate is not high, and a large number of polluting operations, such as traumatic operations and emergency operations caused by traffic, fire and industrial and mining accidents, need to be performed in the hospital. Class IV quasi-clean operating room, as long as there is a major accident, the number of existing class IV quasi-clean operating rooms is sometimes difficult to cope with

If ordinary operations, even polluted operations, are performed in high-level operating rooms, the operating costs will be very high, which is difficult for patients to bear

In order to save energy or reduce operating costs, it is necessary to reduce the air supply volume of the advanced operating room, but the air supply device in the operating room uses local displacement flow (or laminar flow or unidirectional flow), not the turbulent airflow sent by ordinary air outlets. Maintain the cross-sectional wind speed (not lower than 0.15m / s), otherwise the replacement airflow characteristics cannot be maintained, and the cleanliness and sterility level required by the operation cannot be achieved

It can be seen that traditional ideas and measures cannot achieve variable air volume and operating room-level operation
