Abstract

A measuring device for measuring a physiological parameter of an aspirate. The device includes a sensor element for measuring the physiological parameter, a connection port for fluid communication with a medical tube, a collection tube for aspirating and/or collecting the aspirate, a housing, wherein the sensor element is mounted within the housing and a communication passage enabling the aspirate to enter the housing from the collection tube such that the sensor element can measure the physiological parameter. Further, a method for measuring the parameter is disclosed.

Claims

1. A device for measuring a value of a physiological parameter of an aspirate, the device comprising:

a housing;

a sensor element for measuring the value of the physiological parameter, wherein the sensor element is mounted within the housing;

a connection port for fluid communication with a medical tube;

a collection tube for aspirating and/or collecting the aspirate;

a communication passage enabling the aspirate to enter the housing from the collection tube such that the sensor element can measure the physiological parameter; and

a filter element having an opening and disposed between the sensor element and the communication passage,

wherein the housing comprises a first support for supporting the sensor element and a second support for supporting the filter element, the first support comprising at least one pin extending through the opening in the filter element, engaging an inner surface of the sensor element and spacing the sensor element from the filter element.

2. A device according to claim 1, further comprising a pH color reference chart attached to the housing, the chart providing for visual evaluation of the physiological parameter values.
