Autoclaves in medicine

Autoclaves in medicine.

A medical autoclave is a device that uses steam to sterilize equipment and other objects. This means that all bacteria, viruses, fungi, and spores are inactivated. However, prions, like those associated with Creutzfeldt-Jakob disease, may not be destroyed by autoclaving at the typical 134'C for 3 minutes or 121 'C for 15 minutes. Also, some recently-discovered organisms, such as Strain 121, can survive at temperatures above 121 'C.

Autoclaves are found in many medical settings and other places that need to ensure sterility of an object. Many procedures today use single-use items rather than sterilized, reusable items. This first happened with hypodermic needles, but today many surgical instruments (such as forceps, needle holders, and scalpel handles) are commonly single-use items rather than reusable. See waste autoclave.

Because damp heat is used, heat-labile products (such as some plastics) cannot be sterilized this way or they will melt. Some paper or other products that may be damaged by the steam must also be sterilized another way. In all autoclaves, items should always be separated to allow the steam to penetrate the load evenly.

Autoclaving is often used to sterilize medical waste prior to disposal in the standard municipal solid waste stream. This application has grown as an alternative to incineration due to environmental and health concerns raised by combustion byproducts from incinerators, especially from the small units which were commonly operated at individual hospitals. Incineration or a similar thermal oxidation process is still generally mandated for pathological waste and other very toxic and/or infectious medical wastes.

Autoclave quality assurance

Autoclave quality assurance

There are physical, chemical, and biological indicators that can be used to ensure an autoclave reaches the correct temperature for the correct amount of time.

Chemical indicators can be found on medical packaging and autoclave tape, and these change color once the correct conditions have been met. This color change indicates that the object inside the package, or under the tape, has been processed.

Biological indicators contain spores of a heat-resistant bacterium, Geobacillus stearothermophilus. If the autoclave does not reach the right temperature, when incubated the spores will germinate, and their metabolism will change the color of a pH-sensitive chemical.

Some physical indicators consist of an alloy designed to melt only after being subjected to the relevant holding time. If the alloy melts, the change will be visible.

Some computer-controlled autoclaves use an F0 (F-nought) value to control the sterilization cycle. F0 values are set as the number of minutes of equivalent sterilization at 121 'C (250 'F) at 15 psi (100 kPa) above atmospheric pressure for 15 minutes . Since exact temperature control is difficult, the temperature is monitored, and the sterilization time adjusted accordingly.

The use methods and precautions of high-pressure steam sterilization

The use methods and precautions of high-pressure steam sterilization.

Use

(1) in the outer pot and add the right amount of water, will require sterilization of goods into inner pot, cover the lid and symmetrically twisted tight spiral.

(2) to heat the pan to create steam, when the pressure gauge pointer to 33.78kPa, open exhaust valve, the cold air discharge, pressure gauge pointer down at this time, when the pointer down to zero, will soon exhaust valve closed.

(3) continue to heat, steam pot increased pressure gauge pointer to rise to the required pressure when the pressure pot, it will reduce the fire, according to the characteristics of the sterilized items, so that the pressure required to maintain a certain vapor pressure of time , then the sterilizer power or off the fire, let it cool and then slowly open the exhaust valve to exclude the residual gas before opening the lid extract.

2. Note:

(1) Place the items to be sterilized should not be too tight.

(2) must be fully ruled out the cold air, or pot to a temperature of less than the required temperature, affect the sterilization effect.

(3) after sterilization, can not put gas decompression, or bottle of liquid will be intense boiling, wash away the cork and cause spills or even burst the container. Subject to the pressure sterilizer reduced to atmospheric pressure before opening the lid after the same.

(4) loading the tube or bottle of medium cotton stuffed, should be oiled paper or brown paper bag to prevent condensation water from entering.

(5) In order to ensure sterilization, and should regularly check the sterilization effect of common method is to sulfur powder (melting point 115 ¡æ), or benzoic acid (melting point 120 ¡æ) placed in a test tube, then sterilization test. If the material melts, it indicates high-pressure steam sterilizer has reached the temperature required, sterilization effect is reliable. Can also detect sterilization effect of tape (on which there are temperature-sensitive indicator) affixed to the packaging of items to be sterilized, such as adhesive tape color indicator also indicates that sterilization effect is reliable.

(6) now has microcomputer control of the high-pressure steam sterilizer, just put to air, the instrument automatically constant time, the time comes will automatically cut off power and whistle, easy to use.

3. Application: for the most commonly used sterilization methods, generally 101.33kPa handle 15 ~ 20min, can achieve the purpose of sterilization of the items. Where the temperature and humidity of items, such as the common medium, normal saline, clothing, gauze, glass and equipment are all available sterilization law.

The uses of autoclaves

The uses of autoclaves

Autoclaves are widely used in microbiology, medicine, body piercing, veterinary science, mycology, dentistry and podiatry.

Typical loads include glassware, medical waste, utensils, animal cage bedding, and Lysogeny broth.

A notable growing application of autoclaves is in the treatment and sterilization of waste, such as pathogenic hospital waste. Machines in this category largely operate under the same principles as the original autoclave in that they are able to neutralize potentially infectious agents by utilizing pressurized steam and superheated water.

A new generation of waste converters is capable of achieving the same effect without any pressure vessels to sterilize culture media, rubber material, gowns, dressing, gloves etc. It is particularly useful for materials which cannot withstand the higher temperature of hot air oven.

For all glass syringes, hot air oven is a better sterilizing method.

The types of autoclave

The types of autoclave.

There are two main types of Autoclaves: Stove top autoclaves actually resemble a culinary pressure cooker. Each unit comes complete with a bolt-down lid and a pressure gauge on the outside.

These units require an outside heat source and can be extremely dangerous in untrained hands. They should only be used by experienced professionals.

Front loading autoclaves are more widely used for their convenience, but must also be handled with great care. The units are box-shaped and self contained, equipped with a heating unit to turn water into vapor for sterilization.

The autoclave's controls allow the operator to set the desired temperature, and determine how long the machine will remain in operation. There is also a gauge to track chamber temperature/pressure.

What is autoclave

What is autoclave?

An autoclave is a device to sterilize equipment and supplies by subjecting them to high pressure steam at 121 C or more, typically for 15 to 20 minutes depending on the size of the load and the contents. It was invented by Charles Chamberland in 1879, although a precursor known as the steam digester was created by Denis Papin in 1679.
