The anaesthesia machine  is used by anesthesiologists to support the administration of anaesthesia. The most common type of  anaesthesia machine  in use in the developed world is the continuous-flow anaesthetic machine, which is designed to provide an accurate and continuous supply of medical gases (such as oxygen and nitrous oxide), mixed with an accurate concentration of anaesthetic vapour (such as isoflurane), and deliver this to the patient at a safe pressure and flow. Modern machines incorporate a ventilator, suction unit, and patient-monitoring devices.

The original concept was invented by the British anaesthetist H.E.G. Boyle in 1917. Prior to this time, anaesthetists often carried all their equipment with them, but the development of heavy, bulky cylinder storage and increasingly elaborate airway equipment meant that this was no longer practical for most circumstances. The anaesthesia machine is usually mounted on anti-static wheels for convenient transportation.

Simpler anaesthetic apparatus may be used in special circumstances, such as the TriService Apparatus, a simplified anaesthesia delivery system invented for the British armed forces, which is light and portable and may be used effectively even when no medical gases are available. This device has unidirectional valves which suck in ambient air which can be enriched with oxygen from a cylinder,with the help of a set of bellows. A large number of draw-over type of anaesthesia devices are still in use in India for administering an air-ether mixture to the patient, which can be enriched with oxygen. But the advent of the cautery has sounded the death knell to this contraption, due to the explosion hazard.

An X-ray machine is essentially a camera. Instead of visible light, however, X-ray machine uses X-rays to expose the film.

X-rays are like light in that they are electromagnetic waves, but they are more energetic so they can penetrate many materials to varying degrees. When the X-rays hit the film, they expose it just as light would. Since bone, fat, muscle, tumors and other masses all absorb X-rays at different levels, the image on the film lets you see different (distinct) structures inside the body because of the different levels of exposure on the film.

Used in Operation Lamp. There is a trace, cold light, high-intensity characteristics, and color temperature required surgery. Shadowless lighting that surgery should not be the region with a doctor's head, hands and the shadow of surgical instruments in order to ensure a clear surgical cavity to see the organs, tissues and blood vessels, as well as to see the situation in the deep cavity.

   The latest Operation Lamp is a single overall reflector, the lamp light of the diameter of aperture diameter for the illumination region (180 mm) of 4 to 6 times may be 1 meter away from the lights of the region to achieve a trace of requirements. Lighting in the surgery area inside the 500 square centimeters up to 2700 lux illuminance (lx) or more. In order to reduce the high-intensity light to the doctor's head and neck on the thermal and the surface of nerve surgery, like the delicate intestinal anti-heat and easy to dry organ damage, require the most light degrees of heat is not more than 25,000 mm W / cm2. Therefore, almost all glass and light the lamp reflector are plated with cold light to shoot infrared film to minimize the extent of the so-called "cold light."

   Surgery in order to accurately reflect the color of lesion area, and daily habits in the same light color, light and temperature requirements for the 3500 ~ 6000K. Halogen light source used, and add lighting plated glass transmission filter in order to obtain the color temperature. ShadowlessOperation Lamp will generally electronic and remote control technology to improve the lamp body mobility.

Infant incubator for premature infants, low birth weight infants, critically ill children, newborn to provide a similar training of maternal uterine environment equipment, temperature can also be used for the recovery of the infant, infusion, rescue, and so on hospitalized for observation. As the infant's own ability to resist very weak, which requires a stable incubator performance, can provide a more closer to the baby in the mother's womb environment more conducive to the health of babies. Health care workers to understand the basic working principle of their operation to the correct use of equipment performance can be played more.

1, the basic principles of infant incubator

Incubator production currently on the market there are many manufacturers, the basic principles of more or less the same, most have a "convective thermal regulation" provided in the form of an air purification, temperature and humidity environment of a quality suitable for the use of computer technology on the incubator temperature (Box Temperature / skin temperature) to implement the servo control, boot automatically into the state of temperature control box. Temperature controller is the core component of the equipment, temperature settings, real-time temperature monitoring and other functions, when the medical staff can set the temperature when the temperature inside the continuous surveillance. Machinery required to open the perspective of operation and from time to time to change the crib Shizuma good results, so that medical personnel in the care of rest will not affect the baby or the baby woke up, effectively reducing the infant's energy metabolism.

Incubators need to have a reliable alarm system failure, to achieve power, box temperature, skin temperature and the flow duct of the monitoring, if any of the indicators should have exceeded the allowed range of sound and light alarm, prompt attention to the guardianship staff. Incubator alarm when the medical staff found to be an immediate end to the cultivation of the infant, the infant moved to a safe place to ensure the safety of the baby and immediately notify the professional maintenance engineer to carry out maintenance on the equipment, only when the failure to continue to use ruled out entirely.

Incubator use of AC220V power source, must be in strict compliance with the single-phase three-wire system of principles, to ensure a good grounding, apparatus with a network interface for the general infant care network with the infant incubator system to provide a dedicated outlet.

2, the safe use of

Infant Incubator with the work of the state of relations between the baby's safety in the use of health care does not want to be very careful. Before use, to deal with the various functions of the system of checks seriously.

(1) of the power failure, the inspection report to the police function: training course in infants who have any power, would lead to dramatic changes in temperature, endangering the baby's life. In the use of this feature before the inspection, disconnect the power supply AC220V incubator and connected to temperature controller opens the power switch off after the alarm devices should appear, turn off the power switch after the alarm will automatically eliminate. Alarm power supply is provided by the battery, under normal use of the system will automatically charge the battery, the battery has a certain period of use to the period should be to replace the battery.

(2) inspection of the temperature controller: Temperature Controller through the sensor, fan and heating pipe to complete the baby inside of the heating and air circulation, regardless of which components will directly affect the damage to the environment in which the baby. AC220V power supply connected, open the power switch humidity controller, temperature indicator light settings box, set the temperature display flashes to show the temperature control box set the default value 32 ?, do not make any operation, apparatus, automatic temperature control to enter the boxes, and real-time temperature show me the window display of real-time temperature.

(3) over-temperature alarm function checks a set of incubator are generally not subject to the temperature controller to control the independent over-temperature alarm system, temperature control instrument for the failure to monitor the temperature of the box, a measure that greatly the incubator to raise the safety and reliability. Inspection, in boxes under temperature control, set the value to be set at 36 ?, after entering the thermostat, quickly followed by Canada and by key, when the set temperature display window does not show that the temperature controller to enter a state of over-temperature experiment, this heating power when the lights all lit. After about 10min, apparatus should appear over-temperature alarm. By the reset button after the end of over-temperature alarm, apparatus to return to work.

(4) see the inspection report to the police machine: machines work, hold down the finger "to stop fans to" test button, so that fan speed to reduce or stop the rotation, the apparatus should appear bright lights and fan alarm sound alerts.

Confirmed by the inspection device are normal functions, in accordance with the orders set up the parameters to allow the machine to enter the pre-state of the heating apparatus generally in about 45min, but the warm-up time normally required 2h to reach the temperature inside the balance infants are allowed to carry out the training. Show real-time temperature in the instrument settings to achieve the start of the baby on the train is not correct.

Upon completion of the training for each infant, the incubator must be a thorough cleaning, sterilization, disinfection (using the process at least once a week), for some components to be demolished by the cleaning.

The relationship between infant incubator to culture baby's effectiveness and safety in the use of standards when we must, to prevent the accident.

Definition

An x-ray unit is the medical equipment used to produce x rays. Because of the risk of over-exposure to x rays, the x-ray unit includes both the machine used for collecting x rays and the protective room within which the x rays are taken and developed.

Film radiographs, or x rays, are the most widely used means of medical imaging. Radiographs are used to examine bones for fractures, growth abnormalities, and joint dysfunctions. X rays are also used to find abnormal growths in the breasts (mammography), other organs and soft tissues; problems in the gastrointestinal tract; circulatory problems such as clogged arteries and blood clots; and a variety of other ailments. Additionally, radiation therapy to treat cancer is generally performed with x rays.

The production of an x-ray image (radiograph) involves three distinct steps: the generation of an x-ray beam, the interaction of that beam with the structures of the patient to be imaged, and the development of the image.

Visible light is electromagnetic energy that has characteristics that allow it to be seen by humans. There are many other familiar forms of electromagnetic energy that are not visible to humans. These include radio waves, which permit the transmission of radio signals and the operation of cellular phones; microwaves, which are often used to heat food; and x rays. Each of these forms of light has a characteristic size (wavelength) and speed (frequency) range that defines it. An x-ray beam is an invisible form of light that has a wavelength that is much smaller than visible light and a frequency that is much faster than visible light.
