Abstract

A monitor for surveying measurement values indicative of a person'"'"'s breathing, to enable an improved assessment, in terms of conclusiveness and reliability, in the course of a treatment phase or a diagnosis. The monitor has a housing structure defining a gas flow path, a measurement line segment provided in the housing structure and structured to communicate with a breathing gas line segment, a sensor in communication with the gas flow path and structured to generate a signal indicative of the breathing gas flow flowing along the gas flow path, and an electronic recording device to record one or more signals indicative of the breathing gas flow, and/or information derived from them. It thus becomes advantageously possible, in treating a patient by using a CPAP device, for instance, to determine the quality of treatment in an objective and standardized way.

Claims

1. A monitor for surveying signals indicative of a patient'"'"'s breathing, comprising:

a housing structure defining a gas flow path;

a measurement line segment provided to the housing structure and structured to be in communication with a breathing gas line segment;

a sensor provided along the path to generate a signal indicative of the breathing gas flow; and

an electronic recording device to record one or more signals indicative of the breathing gas flow, and/or information derived from the one or more signals.

2. The monitor in accordance with claim 1, wherein the electronic recording device is removable from the housing structures.

3. The monitor in accordance with claim 1, further comprising an interface device to dock a further electronic programming or evaluation system.

4. The monitor in accordance with claim 3, wherein the further electronic programming or evaluation system includes a PC.

5. The monitor in accordance with claim 3, wherein the interface device includes a USB port provided to the housing structure.

6. The monitor in accordance with claim 1, further comprising a pressure detector to generate one or more signals indicative of the breathing gas pressure.

7. The monitor in accordance with claim 1, wherein the electronic recording device comprises an evaluation module to effect evaluation in advance of the recorded measurement signals.

8. The monitor in accordance with claim 7, the evaluation module comprises a software-based evaluation system.

9. The monitor in accordance with claim 1, wherein the monitor is an on-line monitor having a modular structure.

10. The monitor in accordance with claim 1, further comprising a display provided to the housing structure.

11. The monitor in accordance with claim 1, further comprising a power supply.

12. The monitor in accordance with claim 11, wherein the power supply is a battery or a re-chargeable battery.

13. The monitor in accordance with claim 11, further comprising a cover device provided to the housing structure to provide access to a battery chamber provided to the housing structure.

14. The monitor in accordance with claim 1, wherein the recording device comprises a USB flash stick or memory card.

15. The monitor in accordance with claim 1, wherein the measurement line segment is in communication with or provided with a measurement array.

16. The monitor in accordance with claim 15, wherein the measurement array includes a pressure pick up element, a diaphragm device and/or a laminar flow element.

17. The monitor in accordance with claim 1, wherein the signals generated and/or derived from the monitor are used as part of a feedback loop.

18. A CPAP or ventilator system comprising:

a flow generator;

a patient interface;

a breathing gas line segment to communicate the flow generator and the patient interface;

a monitor as claimed in claim 1, said monitor being in communication with the breathing line segment.
