How to Arrange the Hospital Negative Pressure Ward Reasonably?

In order to fight the coronavirus, various countries are vigorously managing and preventing the occurrence of the virus. In order to meet the actual clinical needs of the hospital and ensure medical treatment and eliminate various types of infections in the hospital, the negative pressure ward of the hospital needs to be re-arranged, renovated, and isolated in various areas of the hospital. , Equipped with advanced pass box, disinfection and sterilization equipment and equipment.

The negative pressure isolation ward is an important medical facility for treating highly contagious respiratory infection patients, isolating pathogenic microorganisms and protecting medical staff. The ward needs to be closed, comfortable and clean, and has the rescue function of the ICU ward, which is quite special.

The isolation of the negative pressure ward is divided into process isolation and air isolation. Process isolation is to strictly follow the relevant procedures through the building plane to prevent the leakage of germs. Air isolation is through the application of clean technology, which creates a pressure difference in each area to prevent the bacteria from spreading outward.

Location Selection

The location of the negative pressure ward should be based on the actual situation of the hospital. It should be set as far as possible in the hospital where there is less traffic, away from residential houses, or arranged at the highest level of the building, or at the end of the ward. Entrance and aisle, if there is a separate elevator on the top floor.

Functional Division

The negative pressure ward has strict functional zoning. Four areas are set according to functional requirements:

Staff living area (clean area), work area (semi-polluted area), ward area (polluted area), equipment area (air-conditioning exhaust fan room). The zones are both independent and connected, with buffer zones at the junctions and isolation by cleanroom doors.

The living area (cleaning area) is equipped with a staff lounge, duty room, and toilet. Because after receiving patients, medical staff will also be isolated at the same time, there should be more men and women on duty.

The working area (semi-polluted area) is equipped with a nurse station, treatment room, doctor's office, changing room (one or two), sanitary passage room, buffer room, storeroom, dirty room, and staff toilet. The nurse station is the core of the work area. All patient information, such as ECG monitoring, vital signs information, and monitoring images are reflected on the nurse station monitoring platform. Information such as room temperature and the pressure difference is also displayed on the display of the nurse station. The ward lighting, TV, intercom and other control switches are also set here. The nurse can control and adjust the temperature and lighting according to the different conditions of the patient, and understand the patient's condition at any time through monitoring. The decoration requirements for auxiliary rooms such as doctors' offices, treatment rooms, and dressing rooms are basically the same as those for general wards.

Ward (contaminated area), the ward is set up as a single room, with independent toilets, and the ward has a patient passage to double as a patient activity. In order to avoid the spread of germs, there should be restrictions on the movement space of patients. The front room must be buffered between the work area and the ward. The front room of the ward is provided with an automatic door, and an interlocking self-cleaning pass box is provided between each ward and the front room. The pass box can perform air self-purification through the built-in filter purification fan system.

Wards require comfort, warmth, and soft colors. The floor should be flat and easy to clean. Use durable, non-slip, corrosion-resistant, and easy-to-clean materials. When each area is partitioned, 50mm thick cleanroom wall panel for wall partitioning in each area. When the equipment is cut off, the stainless steel cleanroom panel is used at the front and rear of the sterilizer and washer-disinfector. Materials that are not easily cracked, flame retardant, easy to clean, and resistant to impact should be used. The cleanroom ceiling should adopt an integral suspended ceiling, and LED lamps, high-efficiency air vents, etc. are hermetically embedded in the suspended ceiling. The door can adopt a color steel cleanroom door, steel cleanroom door, double-layer cleanroom window, and the door and window frame adopt electrophoretic aluminum alloy.

All seams in the negative pressure ward area must be flat and tight, and there must be no air leakage. Neutral sealant should be used to fully seal the gaps on the ground, cleanroom windows, walls, ceilings, etc. All manholes and doors on the ceilings and walls must be sealed to ensure the formation of negative pressure airflow Architectural decoration is equivalent to operating room requirements.

Nosocomial infection is a major obstacle to hospital quality and an important indicator for evaluating the quality of medical care and management. Doing a good job in the layout of the hospital's negative pressure ward to ensure that the quality of disinfection and sterilization items is fully qualified is an important guarantee to prevent hospital infection. Therefore, the reasonable layout and equipment configuration of the negative pressure ward is the guarantee of hospital disinfection supply.
