Abstract

A two-part probe (5) is for a pneumatic gas delivery system (100) with a breathing system (1) and a pneumatic interface (3) of a ventilator (700) or anesthesia device (500). The two-part probe (5) enables gas exchange (29) between the breathing system (1) and the pneumatic interface (3) by means of a channel arrangement (10).

First claim

What is claimed is:

1 . A probe for a pneumatic gas delivery system with a breathing system and a pneumatic interface of a ventilator or anesthesia machine, the probe comprising:
a probe element; a conduit element, wherein the probe is a combination of the probe element with the conduit element as a two part configuration with the combination of the probe element and the conduit element forming a probe channel and a feedthrough channel of at least one channel arrangement internal to the probe to provide a pneumatic or fluidic conductive connection between the breathing system and the pneumatic interface, wherein the probe element is connectable to the conduit element and the probe element together with the conduit element forms the probe in an interconnected state, wherein a fluid exchange connection between the probe element and the conduit element is enabled by the channel arrangement; and a connection element arranged on the conduit element, wherein the probe is connectable to the pneumatic interface or to components of the ventilator or to components of the anesthesia machine by the connection element.

2 . A probe according to claim 1 , wherein the probe is configured as a measuring probe for a gas exchange via the pneumatic interface and comprises at least one probe opening arranged in the probe element, wherein via the at least one probe opening, the probe channel inside the probe element and the feedthrough channel inside the conduit element, a transmission of a pneumatic flow rate prevailing in the breathing system is enabled to transmit a pneumatic and/or physical situation prevailing in the breathing system to a sensor interface connected to a pneumatic interface or to sensors connected to the pneumatic interface.

3 . A probe according to claim 1 , wherein the probe is configured as a gas inlet for a gas exchange by the probe and comprises at least one probe opening arranged in the probe element, wherein via the at least one probe opening, the probe channel inside the probe element and the feedthrough channel inside the conduit element, a flow of gas quantities is enabled from the pneumatic interface into the breathing system.

4 . A probe according to claim 1 , wherein the probe is configured as a gas outlet for a gas exchange by the probe and comprises at least one probe opening arranged in the probe element, wherein via the at least one probe opening, the probe channel inside the probe element and the feedthrough channel inside the conduit element, a flow of gas quantities is enabled from the breathing system into the pneumatic interface.

5 . A probe according to claim 1 , wherein the fluid exchange connection between the probe element and the conduit element is formed as a releasable screw connection as a threaded combination with an externally threaded element and an internally threaded element corresponding thereto.

6 . A probe according to claim 1 , wherein the fluid exchange connection between the probe element and the conduit element is formed as a tool-less, releasable connection.

7 . A probe according to claim 1 , wherein the probe element further comprises a second probe channel and the conduit element further comprises a second feedthrough channel.

8 . A probe according to claim 7 , wherein the probe element comprises a probe opening and further comprises a further probe opening to provide a pneumatic or fluidic conductive connection between the breathing system and the pneumatic interface via the second probe channel and the second feedthrough channel, wherein the second probe channel and the probe channel form a coaxial arrangement with each other, wherein one of the probe channels is internally disposed in the other probe channel, and wherein the second feedthrough channel and the feedthrough channel form a coaxial arrangement with each other and wherein one of the feedthrough channels is internally disposed in the other feedthrough channel.

9 . A probe according to claim 8 , wherein a volume element is arranged or integrated in or on the probe, the probe element, the conduit element, the channel arrangement, one or more of the probe channels, one or more of the feedthrough channels or the connection element, and wherein the volume element is configured to buffer pressure differences, reduce pressure surges in the breathing system or the pneumatic interface or dampen movement of gas quantities between the breathing system and the pneumatic interface.

10 . A probe according to claim 1 , wherein a volume element is arranged or integrated in or on the probe, the probe element, the conduit element, the channel arrangement, the probe channel, the feedthrough channel or the connection element and wherein the volume element is configured to buffer pressure differences, reduce pressure surges in the breathing system or the pneumatic interface or dampen movement of gas quantities between the breathing system and the pneumatic interface.

11 . A probe according to claim 1 , wherein the probe element and/or the conduit element comprise at least one sealing element providing a gas-tight connection between the probe element and the conduit element, and wherein the conduit element comprises at least one sealing element providing a gas-tight between the conduit element and the pneumatic interface.

12 . A probe according to claim 11 , wherein:
the probe and/or the conduit element and/or the probe element and/or at least one of the sealing elements is formed of a plastic material, and/or the probe and/or the conduit element and/or the probe element is formed of a plastic material or a metallic material.

13 . A probe according to claim 1 , in combination with the breathing system and the pneumatic interface to form an arrangement, the probe being arranged on the breathing system, wherein:
with the probe configured as a measuring probe, a detection of a pneumatic and/or physical situation in the breathing system is enabled, and/or with the probe configured as a gas inlet, a flow of gas quantities is enabled from the pneumatic interface into the breathing system; and/or with the probe configured as a gas outlet, a flow of gas quantities is enabled from the breathing system into the pneumatic interface.

14 . A probe according to claim 13 , wherein the arrangement comprises a pneumatic gas delivery system or an anesthesia machine or a ventilator and further comprises:
at least one pressure sensor; and/or at least one temperature sensor; and/or at least one gas sensor; and/or at least one humidity sensor; and/or at least one flow rate sensor.

15 . A probe according to claim 13 , wherein the arrangement further comprises at least one connection line between the connection element at the conduit element of the probe with the pressure sensor and/or the temperature sensor and/or the gas sensor and/or the humidity sensor and/or the flow rate sensor.

16 . A probe according to claim 13 , wherein the arrangement further comprises a second probe to provide at least two probes, wherein pneumatic or fluidic connections between the breathing system and the interface via the two probes are formed by mutually unique and unmistakable configurations of a thread combination on the two probe elements and/or unique and unmistakable configurations of the connection elements on the conduit element of the two probe elements.

17 . A gas delivery system comprising:
a breathing system; a pneumatic interface; and a probe comprising: a probe element; a conduit element, wherein the probe is a combination of the probe element with the conduit element as a two part con
