Sterile single use measurement device

A sterile single use measurement device, comprising:

• an elongated measurement probe comprising a first end and a second end,
• a sensing element for measuring a physical property, which is located on said first end of said elongated measurement probe;
• a sterile tubing comprising a first end, a second end and a compressible section located between said ends, said sterile tubing surrounding said elongated measurement probe, such that said second end of said elongated measurement probe extends out of said second end of said sterile tubing;
• means for establishing a sterile connection between said first end of said sterile tubing and a corresponding counter part on a measurement site, wherein said sterile connection forms a passageway leading into a measuring chamber on said measurement site, wherein said physical property is to be measured;
• and
• a thermal weld providing a sealed mechanical connections between said second end of said sterile tubing and said elongated measurement probe,
• wherein:
• said compressible section of said sterile tubing allows for a length of said sterile tubing to be varied, such that said sensing element is entirely located inside said sterile tubing, when said compressible section is uncompressed, and said sensing element is located outside said first end of said sterile tubing when said compressible section is compressed.

A method of installing a sterile single use measurement device, having:

• an elongated measurement probe comprising a first end and a second end;
• a sensing element for measuring a physical property, which is located on said first end of said elongated measurement probe;
• a sterile tubing comprising a first end, a second end and a compressible section located between said ends, said sterile tubing surrounding said elongated measurement probe, such that said second end of said elongated measurement probe extends out of said second end of said sterile tubing;
• means for establishing a sterile connection between said first end of said sterile tubing and a corresponding counter part on a measurement site, wherein said sterile connection forms a passageway leading into a measuring chamber on said measurement site, wherein said physical property is to be measured;
• and a thermal weld providing a sealed mechanical connections between said second end of said sterile tubing and said elongated measurement probe, wherein:
• said compressible section of said sterile tubing allows for a length of said sterile tubing to be varied, such that said sensing element is entirely located inside said sterile tubing, when said compressible section is uncompressed, and said sensing element is located outside said first end of said sterile tubing when said compressible section is compressed, on a measurement site, comprising the steps of:
• mounting the device on the measurement site via the sterile connection;
• and
• transferring the sensing element into the measurement chamber by compressing the compressible section of the sterile tubing.
