O que é um autoclave?

Definição e princípio básico

Autoclaves function as specialized pressure vessels that sterilize equipment by using high-pressure saturated steam. Autoclaves operate based on the principle that pressurized steam achieves temperatures exceeding those of boiling water to kill bacteria, viruses, fungi, spores, and other microorganisms. Autoclaves achieve complete sterilization by holding precise temperature and pressure levels for a set duration and they are indispensable in environments where controlling contamination is essential.

Contexto histórico

The idea of using steam to achieve sterilization first emerged during the 19th century period. The initial prototypes served as the basis for contemporary autoclaves which now operate as advanced machines equipped with automated controls and enhanced safety features. Modern autoclaves comply with strict industry requirements while utilizing state-of-the-art technology to improve their performance and ensure both reliability and user safety.

Como é que um autoclave funciona?

A ciência por detrás da esterilização

Autoclaves function by applying pressurized steam to sustain temperatures that exceed 100°C (212°F). Standard operating conditions include 121°C at 15 psi for 15-20 minutes but can be modified for different loads and materials.

Principais etapas do ciclo de esterilização

  1. Carregamento: The autoclave chamber receives all items set for sterilization. Correct item arrangement in the autoclave chamber guarantees steam reaches all surfaces for efficient sterilization.
  2. Remoção de ar: The chamber air is removed using gravity displacement or a vacuum system to ensure steam fully contacts all surfaces.
  3. Fase de esterilização: The autoclave chamber receives pressurized steam which heats up to the predetermined temperature and sustains it throughout the necessary time period.
  4. Escape: Following sterilization steam release brings the chamber back to its normal atmospheric pressure.
  5. Secagem: Certain autoclaves feature a drying phase which eliminates remaining moisture from the sterilized objects.
  6. Descarga: Items can be taken out of the chamber for use or storage as soon as the cycle ends and the chamber becomes safe to open.

Tipos de autoclaves

Autoclaves de deslocamento por gravidade

The most frequently used autoclave models operate by allowing gravity to push air out of the chamber and replace it with steam. They work best when sterilizing liquids, glassware and basic instruments.

Pre-Vacuum (High Vacuum) Autoclaves

Pre-vacuum autoclave models utilize a vacuum pump to extract air before steam introduction which results in superior steam penetration of porous substances and advanced instruments.

Pulse Vacuum Autoclaves

The pulse vacuum autoclaves work by alternating vacuum and steam pulses which optimizes air removal and improves the sterilization process for difficult loads.

Autoclaves horizontais e verticais

Both horizontal and vertical autoclave designs exist to meet different space limitations and operational requirements.

Componentes principais

  • Câmara: The main vessel where sterilization occurs.
  • The steam generator creates the essential steam required for the sterilization process.
  • The control panel enables users to configure and track sterilization cycle settings.
  • Safety valves maintain operational safety through pressure regulation.
  • Gaskets and Seals provide airtight protection inside the chamber.
