Medical Hospital Negative Pressure Compartment Isolation Stretcher Transfer Bed Equipment

Medical Hospital Negative Pressure Compartment Isolation Stretcher Transfer Bed Equipment

Technical Specification

1. Product basic principles
    The negative pressure isolation compartment (bed) is established by the clean unit and maintains the negative pressure environment in the closed cavity. The polluted air in the wall cannot overflow without purification, thereby providing effective protection for medical staff; fresh air outside can be replenished in real time after purification Into the cavity, maintain reasonable fresh air in the cavity; through medical PVC gloves at the operation port, medical staff can provide simple care to the patient. The negative pressure isolation cabin is a completely enclosed space, which can play a good isolation role in transferring suspected or confirmed cases. It can be used for SARS, avian influenza, HINI, Ebola, new  and other patients Isolation and delivery is a new product for the prevention and control of new  epidemics.
Product design

(1) Structural design
    The negative pressure isolation cabin is mainly composed of a foldable cabin and a clean unit. The cabin uses a foldable, highly transparent TPU membrane material to form a relatively closed space, and the clean unit consists of high-efficiency filters, pressure differential monitoring, DC fans, and so on. The entire cabin body is made of TPU film heat-sealed. The cabin body is airtight, high mechanical strength, overall permeability, and no patient depression. In the choice of support structure, the arc-shaped support made of ABS material is used. The corners are dull to reduce the harm to the human body; the overall housing of the negative pressure generation system is made of ABS material, which integrates high-efficiency filters, DC fans, control units, lithium batteries, negative pressure testers and other components at the air outlet, and is waterproof. And corrosion resistance, real-time monitoring of cabin pressure, battery power display and other functions; Finally, the high-efficiency filter housing also uses ABS material, which not only achieves high filtration efficiency and guarantees the effect of low air pressure drop. For 0.3 μm The filtration efficiency of the particulate aerosol is not less than 99.99%, which can effectively prevent the overflow of infectious bacteria.

(2) Control design
    Design an intelligent control system based on a single-chip microcomputer. The built-in single-chip microcomputer controls the fan speed. The internal pressure is collected by a pressure sensor. When the internal pressure is higher than -15 Pa, the single-chip microcomputer controls the fan to automatically adjust the speed and control the LED lights and buzzer for sound and light. Alarm; integrated operation panel with power display and alarm, cabin pressure display and alarm and other functions, and has the ability to waterproof and corrosion resistance. The distribution of airflow inside the cabin has an important impact on the safety performance of the negative pressure isolation cabin. How to reasonably distribute the air flow in the cabin to achieve a good flow and dispersion effect is very important for the safe isolation of infectious bacteria in the cabin. In the design, Fluent software was combined with the fan characteristic curve, and the multiphase flow model turbulence model was used to test the airflow field in the cabin. According to the actual operation of the negative pressure isolation cabin, the air outlet plane at the negative pressure generating system is set as the cabin air outlet, and the pressure is given by the fan curve. The height of the opening of the high-efficiency filter on the bottom side is consistent with the height near the mouth of the simulated infectious patient, and it is set as the air inlet. Infectious patients often have sneezing symptoms. The simulated air velocity of the mouth of the patient is about 2 m / s. Simulation tests based on the multiphase flow model turbulence model show that the flow and dispersion of the airflow in the cabin is good, and there is no airflow short circuit.
