Currently the world is in a situation where market needs and consumer demand have changed, now the need is for hospital products, medical clothing, pharmaceuticals, respirators, cleaning products and basic necessities.
A breathing machine has the function of breathing for you. Also called mechanical respirators or life support.
They are mainly used in hospital intensive care – UCI- patients who present respiratory deficiencies, they can also be built in ambulances or emergency areas and for domestic use for homes.
Air and oxygen enter into the respirator thanks to the external pneumatic system, in this place there is a pressure gauge regulator that allows to decrease their pressure and keep it constant. Connected is the microprocessor, which will give the order of how this flow should be, a system called a proportional solenoid will open that infuse the air into the patient. It has a safety valve, which allows the pressure to be lowered, in the event of the respirator being switched off, ensures the entry of ambient air. A one-way valve will prevent exhaled air from passing into the same inspiratory circuit. When the inspiration ends the respirator have “cycled”, then the expiratory valve opens, the gases pass through a filter, a flow sensor measures the volume of gas exhaled. As the gas comes out, the pressure decreases. If PEEP has been programmed, the ventilator will close the exhalation valve when it reaches the defined level.
PARTS OF A BREATHING MACHINE
- Upper medication tray: This is where the equipment's control and programming elements are located, as well as the necessary measurement elements to maintain adequate levels of oxygen in the patient.
- Ventilation filters: These are responsible for removing dust and other pollutants from the air so that when these elements are provided to the patient don’t affect their health.
- Air connector: The air supply is connected to this terminal from an individual tank or a network that the health center has.
- Oxygen connectors: Like the previous item, an external gas supply must be connected to the appliance for this operation.
- Water trap: This reduces the pressure of the gases to be properly supplied to the patient.
- Interface connectors: These are the data acquisition ports that the ventilation system has.
- Valves: These has the function of opening or closing according to the point of the cycle in which the equipment is operating.
- Fuse box: essential to prevent changes in the electric current from burning the electronic system of the equipment.
- Sockets: they are the cables necessary for connection to the electrical network.
- Most of the elements for this artefact are built in plastic and derived materials, these have a low mechanical resistance to impact, so that the equipment is susceptible to being fractured or affected by blows produced by poor loading and unloading processes.
- The equipment has different measuring elements in which it is of great importance to preserve its calibration or valve seals, so these elements must be protected from environmental factors and shocks that may be suffered.
- Care should be taken not to have equipment close to a heat source, as it can reach a flash point by creating a fire inside of transport or place of storage.
- Since they are for medical use, the loading units must be cleaned and disinfected in order to preserve the harmless characteristics of the equipment.
- Although the equipment is mostly made of plastic elements and derivatives, also has metallic parts, which can be corroded by exposure to oxygen and water in the air, therefore it is recommended to protect these elements from contact with environments where salt is present in the air.
- The equipment has small parts that are susceptible to be lost during transport, so they must be packed together with the other parts of the equipment taking care that the packaging doesn’t have openings through which they can leave the interior.
- The screen of the equipment is made of fragile material, so it must be protected with foam material so that it’s not damaged in transit.
