Abstract

A diagnostic medical device which monitors physiological parameters during sleep is disclosed. The device includes mask means (2) adapted to fit over the nose and mouth of a patient being monitored, and an acquisition unit (5) is adapted to be removeably fitted to the mask means (2). The mask means (2) has inlet means (3) to allow the patient to breath, sensor means (8) which monitor physiological conditions and which provide physiological signals thereto for storage or real time data transmission to external devices.

Claims

1. A diagnostic medical device which monitors physiological parameters during sleep, said device including mask means adapted to fit over the nose and mouth of a patient being monitored, and an acquisition unit being adapted to be removeably fitted to the mask means, said mask means having inlet means to allow the patient to breath, and wherein said acquisition unit includes sensor means which monitor physiological conditions and which provide physiological signals thereto for storage or real time data transmission to external devices.

2. A diagnostic medical device according to claim 1, wherein the mask means is a standard nebuliser mask used for oxygen ventilation and respiratory support having ventilation holes for an external air supply.

3. A diagnostic medical device according to either claim 1 or claim 2, wherein the mask is made from soft plastic and the acquisition unit is attached to the mask by means of anchors protruding through pre-punched holes in the soft plastic of the mask.

4. A diagnostic medical device according to any one of the preceding claims, wherein the inlet means is adapted to be provided for positive pressure oxygen intake, connection of air mass flow measurement devices or air pressure sensors.

5. A diagnostic medical device according to any one of the preceding claims, wherein the sensor means are located internally of the body of the acquisition unit.

6. A diagnostic medical device according to any one of claims 1 to 5, wherein the sensor means are located externally of the body of the acquisition unit.

7. A diagnostic medical device according to any one of the preceding claims, wherein a temperature sensor is positioned within the mask and an ear mounted pulse oximeter spring clip assembly is connected to the acquisition unit via short leads, and wherein EEG electrodes and ECG and plethysmography leads are also connected to the acquisition unit via short leads.

8. A diagnostic medical device according to any one of the preceding claims, wherein a connector is used for recorded data uploading and internal battery re-charging or for a real time data transmission.

9. A diagnostic medical device according to any one of the preceding claims, wherein the device monitors any one or more of the following physiological signals:

air flow, air pressure, air temperature, ECG signal, EEG signal, plethysmography signal for chest movement monitoring, or oximetry.
