Abstract: The invention relates to an arrangement for the quantitative analysis of respiratory gases to and from a patient connected to a respirator for breathing assistance, wherein the arrangement includes an adapter (1) that has connections (4) for a respirator or the like and connections (3) for a hose leading to teh patient, wherein the adapter includes between the respirator connection (4) and the hose connections (3) a passive respiratory gas humidifier (4), wherein a connection for a measuring head (2) for a gas analyser is provided between the passive humidifier (14) and the respirator connection (4), and wherein the measuring head connection includes two windows (7) through which rays of light from the measuring head (2) can pass.

Abstract: The present invention relates to an arrangement for the quantitative analysis of respiratory gases to and from a patient connected to a respirator for breathing assistance, wherein the arrangement includes an adapter (1) that has connectors (4) for connection to a respirator or the like, and connectors (3) for connection to a hose (13) leading to the patient. The adapter (1) in accordance with the invention, the arrangement includes a fuel cell (18) located between the respirator connector (4) and the connectors (3) for connecting the hoses leading to the patient; and in that the adapter (1) also includes a bacterial filter (15; 17) for protecting the fuel cell (18) from bacteria in the respiratory gases.

Abstract: An arrangement for the quantitative analysis respiratory gases to and from a patient connected to a respirator for breathing assistance, includes an adapter (1) having connectors (4) for connection to a respirator or the like, and connectors (3) for connection to a hose (13) leading to the patient. A connection for a measuring head (2) for a gas analyser is provided in the adapter (1) between the respirator connector (4) and the connectors (3) for connecting the hoses to the patient. The measuring head connection includes two windows (7) through which rays of light from the measuring head (2) can pass; and the adapter (1) also includes a connection (16) for a fuel cell (18) for measuring the oxygen gas content of the respiration gases.

Abstract: A diaphragm pump includes a pump housing having an inlet and an outlet for the fluid. The pump housing (2) includes a partition wall (4) which delimits two chambers (3) on a respective side of the partition wall. The two chambers are each closed by a respective diaphragm (9) connected to an electric coil (12) for causing the diaphragm to oscillate in coaction with a magnetic unit (14-16), therewith pumping the fluid.

Abstract: A moisture and heat exchanging unit for a respiration device such as a tracheal tube or tracheotomy canula, is described comprising a housing holding therein a moisture and heat exchanging body and/or a bacterial filter, said housing comprising two halves, a proximal half having an opening for connection with the airways of a patient and a distal half having an opening for communication with an air supply, said halves being mutually rotatable around a circular connection, one of said halves having an enlarged rim portion in locking, rotatable, relationship with a lid edge of the other of said halves. In a further embodiment, said halves are sealing against each other by an annular blade with tapering cross-section integral with one of said halves, sealing against an inclined internal surface of a collar integral with the other of said halves.

Abstract: A device for gas analysis, which determines the content of two or more gases in a gas flow. The device includes at least one source for emission of two or more ray paths of radiation of a detectable wavelength, a cuvette device having an inlet and an outlet for uninterrupted gas flow, and a detector device for conversion of the radiation into an electrical signal. The source(s), cuvettes, and detectors are arranged such that ray paths emitted from the source pass through cuvettes containing gas and to detectors to permit analysis of two or more gases in a gas flow. In a preferred embodiment, the cuvette device includes a block having cuvettes positioned in each of the ray paths, which cuvettes are interconnected to form an unbroken conduit for gas flow from inlet to outlet.
