Abstract
A portable anesthetic delivery device includes a breathing circuit. The breathing circuit includes a container having a support member holding a carbon dioxide absorber configured to remove carbon dioxide generated during an anesthetic procedure. The container has an outlet port, an inlet port and a removable top portion. A connector assembly has a first unidirectional check valve that is detachably and airtightly connectable to the outlet port of the container via a first tube and a second unidirectional check valve that is detachably and airtightly connectable to the inlet port of the container via a second tube. A pressure sensor is attached to the top portion of the container. The pressure sensor is configured to measure pressure within the breathing circuit.
Claims20
A portable anesthetic delivery device, comprising:
- a breathing circuit having:
- a container having a support member holding a carbon dioxide absorber configured to remove carbon dioxide generated during an anesthetic procedure, the container having an outlet port, an inlet port and a removable top portion, wherein the removable top portion of the container has an opening formed therein, and wherein a first layer of a transparent infrared absorbing material is positioned inside the opening;
- a connector assembly having a first unidirectional check valve that is detachably and airtightly connectable to the outlet port of the container via a first tube and a second unidirectional check valve that is detachably and airtightly connectable to the inlet port of the container via a second tube, wherein the connector assembly comprises a three-way Y-junction having a first member, a second member and a third member, wherein the first unidirectional check valve is fluidly coupled to the third member and positioned between the three-way Y-junction and the first tube without a change in direction along a length of the third member until connection with the first tube, and wherein the second unidirectional check valve is fluidly coupled to the second member and positioned between the three-way junction and the second tube without a change in a direction along a length of the second member until connection with the second tube;
- and
- a pressure sensor attached to the top portion of the container, the pressure sensor configured to measure pressure within the breathing circuit.

A method of anesthetizing a large animal, comprising the steps of:
- providing an anesthesia agent into oxygen in a breathing circuit for delivery as a mixture to the large animal during an anesthetic procedure;
- measuring pressure within the breathing circuit;
- and
- controlling a flow rate of the mixture based on the measured pressure as the mixture travels through the breathing circuit to the large animal so that the large animal receives a desired amount of anesthesia agent based on the controlled flow rate;
- wherein the breathing circuit comprises
- a container having a support member holding a carbon dioxide absorber configured to remove carbon dioxide generated during an anesthetic procedure, the container having an outlet port, an inlet port and a removable top portion and is connected to an anesthesia gas source, wherein the removable top portion of the container has an opening formed therein, and wherein a first layer of a transparent infrared absorbing material is positioned inside the opening;
- a connector assembly having a first unidirectional check valve that is detachably and airtightly connectable to the outlet port of the container via a first tube and a second unidirectional check valve that is detachably and airtightly connectable to the inlet port of the container via a second tube, wherein the connector assembly comprises a three-way Y-junction having a first member, a second member and a third member, wherein the first unidirectional check valve is fluidly coupled to the third member and positioned between the three-way Y-junction and the first tube without a change in direction along a length of the third member until connection with the first tube, and wherein the second unidirectional check valve is fluidly coupled to the second member and positioned between the three-way junction and the second tube without a change in a direction along a length of the second member until connection with the second tube;
- and
- a pressure sensor attached to the top portion of the container, the pressure sensor configured to measure pressure within the breathing circuit.
