Problems solved by technology

Another disadvantage of this solution is that the sensor cannot be installed without a nasal cannula
Therefore, the patient must wear a nasal cannula during this method

Embodiment Construction

[0044] By providing a system and method for tightly attaching the device to the nasal septum without applying excessive pressure on the tissue, the described system and method overcome the above-mentioned problems. The nasal septum has several benefits for measuring SpO2 and PPG signals because the nasal septum is an extremely thin and well-perfused part of the body and can be detected according to the transmission geometry, in contrast to the reflection geometry utilized by the forehead probe. The nasal septum as a measurement site also has the benefit of being one of the last well-perfused sites when the patient enters a state of shock. Therefore, several systems and methods for stably fixing the blood oxygen sensor to the nasal septum are described herein.

[0045] Figure 1A to Figure 1D Illustrated is a septal pulse oximeter 10 according to one or more aspects described herein, which can be attached to the nasal septum of a patient in a stable manner. Figure 1A The oximeter ...

Abstract

When measuring SpO2 in a patient, a nasal oximeter is inserted into the patient's nose and comprises a source pad (14) and a detector pad (18) that are positioned at a predetermined location on either side of the nasal septum. The source pad and detector pad are biased toward each other to provide a clamping force on the nasal septum sufficient to permit SpO2 measurement without causing tissue necrosis. Clamping force is supplied by means of a spring type device, an expandable material, or the like.

Description

Technical field [0001] The invention is applied in the pulse oximetry measurement system and method. However, it should be understood that the described technology can also be applied in other vital sign measurement systems, other sensor placement technologies, and so on. Background technique [0002] In the intensive care unit (ICU) or operating room (OR), certain parameters of the human body need to be evaluated. Because two of these parameters are of particular concern, they are photoplethysmography (PPG) and pulse oximetry (SpO2), so these two parameters need to be measured in a reproducible way. Under normal circumstances, these sensors are extremely sensitive to movement, and the signals respond accordingly, making them extremely unreliable. [0003] In addition to the movement problem, there is also the problem that conventional PPG / SpO2 sensors perform poorly in patients with low perfusion conditions, especially when the sensor is positioned on the fingertip. Hypoperfusi...
