Anesthesia Induction Chamber

The Anesthesia Induction Chamber is used to confine the rodent in a closed space during anesthesia procedures. The transparent material helps in visualizing the physical state of the subject; thus preventing accidental overdosing.

An anesthesia induction chamber for rodents is a small, enclosed space designed to safely administer inhaled anesthesia to small animals such as mice or rats. The chamber is typically made of clear plastic and has a small opening for the animal to enter. Inside, the chamber has a supply of anesthetic gas, such as isoflurane, which is used to induce and maintain anesthesia during procedures. The chamber is connected to a gas source and a ventilation system to ensure that the animal is breathing the correct concentration of anesthetic gas throughout the procedure. Anesthesia induction chambers are commonly used in research settings to ensure the safety and comfort of the animals during experiments.

Low stress Anesthesia Induction chamber

Rodents lack cone cells that sense red light and are insensitive to red light.The red transparent appearance is convenient for the experimenter to observe the stateof the animal while reducing the stress response of the animal and reducing the impacton the biological rhythm of the animal. Comply with animal welfare.

Anesthesia Induction Chambers

ConductScience’s Anesthesia Induction Chamber is a state-of-the-art apparatus contrived from supreme quality acrylic. It is used to confine subjects during an induction procedure. The box is provided with two adjacent orifices; an inlet for the entry of the fresh anesthetizing gas and an outlet for scavenging the waste gas material. The transparent material helps in visualizing the physical state of the subject; thus preventing accidental overdosing. The Anesthesia Induction Chamber can be controlled by a flowmeter with inlet air ranging from 0.1-4L/min.

The subject(s) should be carefully placed into the box, and the supply of fresh anesthetizing should be initiated and maintained for approximately 2 to 5 minutes. After the subject is fully anesthetized, the anesthesia supply should be discontinued.

Critical: Do not open the anesthesia box immediately, wait for about 10 to 15 seconds so that oxygen in the box neutralizes the gas concentration.

Finally, the chamber should be opened slightly, just enough to remove the anesthetized subject from the box, and closed immediately.

Caution: Do not wide open the chamber, just enough so that a hand can be introduced for the removal of the subject.

By keeping the opening far away from the experimenter and limiting the time that the box is open, the risk of exposure to the experimenter will be diminished.

Optimal Benefits Achieved Through Our Exceptional Design

  • Our design is preferred over the conventional mask and circuits because it is less time-consuming and it can hold and anesthetize more than one subject simultaneously.

  • Our special design provides extra protection to the experimenter by keeping the opening far away from the experimenter.

    Our device is compatible with almost all (non-explosive) gas mixtures. However, it should not be used with liquid organic solvents.

  • Our scavenging tube efficiently removes the waste gas materials.

Documentation

A fundamental component of surgical procedures in animal research is the usage of anesthetics. Anesthesia is an important tool to restrain animals during procedures that may either cause excessive stress to the animal or expose the researcher to unavoidable hazards, as well as post-surgery pain management. The surgical methods that are sure to cause pain or discomfort in animals must, therefore, be performed under general anesthesia (“Anesthesia and Analgesia in Laboratory Animals,” 2010). Anesthesia may be inhaled or injected depending on factors such as type and duration of surgery and animal species.

The process of putting animals under inhalant anesthesia is made easier with the use of an anesthesia box that confines subjects during the anesthesia induction procedure. It is also provided with two separate openings, an inlet for the entry of fresh anesthetizing gas and an outlet for scavenging the waste gas material. To prevent accidental overdosing, the apparatus is made of transparent acrylic for easy observation of the animal

Apparatus and Equipment

The anesthesia box is a state-of-the-art apparatus manufactured from supreme quality acrylic, used to enclose animals during inhalant anesthesia induction procedures. The transparent acrylic material is used for convenient inspection of the animal’s physical state, in order to prevent any possibility of accidental overdose.

Protocol

The anesthesia box must be carefully placed on an even and stable surface. Depending on its size, the anesthesia box may accommodate more than one animal.

Once the animal is carefully placed inside the empty anesthesia box, the supply of fresh anesthetizing gas is then initiated and maintained for approximately 2 to 5 minutes. The supply should then be discontinued once the animal is fully anesthetized. A critical step is to wait for about 10 to 15 seconds after the anesthesia supply is cut off so that the oxygen in the box neutralizes the gas concentration. Once the animal is retrieved through a slight opening in the top lid, the anesthesia box is immediately closed to prevent the unwanted escape of gas. Once the animal is moved out of the chamber, anesthesia may be maintained via other tools, such as the cone device.

Applications

The discovery of general anesthesia during the middle of the 19th century can be considered one of the most important developments in the history of medicine (Werner et al., 2011), and since then, its usefulness has found other important applications, such as animal research.

Much of research in the neurosciences is benefited from the use of experimental animals. A huge aspect of animal research is the employment of surgical procedures, and ethical considerations necessitate anesthesia as a tool for eliminating any unnecessary stress, pain, or discomfort the animal may experience during and after surgery. Today, there are many novel and sophisticated methods for administering different types of anesthesia, but the mechanisms have not changed. The anesthesia box presents a convenient way of employing gas induction procedures, with such substances as isoflurane, sevoflurane, and other inhalant agents, that, through inlet and outlet openings of gas and a transparent, sealed design, ensures the safety of everybody involved.

Strengths and Limitations

The anesthesia box’s design is much preferred over the conventional mask and circuit method because it requires less time for the inhalant anesthesia to take effect. Further, the anesthesia box can hold and anesthetize more than one animal simultaneously, depending on its size.

It is a reality that exposure to waste anesthetic gas is a serious occupational hazard (“Anesthesia and Analgesia in Research Animals,” 2012). The experimenter’s safety is, therefore, another concern that the anesthetic box’s design succeeds in addressing. The anesthesia box’s special design provides extra protection to the experimenter by keeping the opening on the farther side to avoid exposure. Additionally, the anesthesia box is compatible with most non-explosive gas mixtures. The outlet scavenging tube is also an efficient addition to the anesthesia box’s design, effectively removing toxic waste gas materials.

Summary

  • An anesthesia box is a tool used for confining animal subjects in a closed space during anesthesia induction procedures.
  • To prevent accidental overdosing, the apparatus is made of transparent acrylic for easy observation of the physical state of the animal.
  • The anesthesia box ensures the safety of experimenters from accidental exposure to waste anesthetic gas.
