Reflective wrist oximeter with electrocardiograph function

Abstract

The invention relates to a reflective wrist oximeter with an electrocardiograph function, which comprises a blood oxygen acquisition module, an electrocardiosignal acquisition module, a processing module, a display module, a shell and wrist bands, wherein the blood oxygen acquisition module comprises a light-emitting driver, a light-emitting tube and a photosensor; the light-emitting tube and the photosensor are arranged at the same side of a position to be detected, and an included angle having preset degrees is formed between the light-emitting tube and the photosensor; the electrocardiosignal acquisition module comprises a first electrode and a second electrode and is used for acquiring electrocardiosignals; the processing module is used for processing pulse blood oxygen data acquired by the acquisition module and the electrocardiosignals acquired by the electrocardiosignal acquisition module; the display module is used for displaying information processed by the processing module to a user; the wrist bands are connected to both sides of the shell; the first electrode is arranged at one side of the shell, which is in contact with the wrist; the display module is arranged at the other side of the shell, which is opposite to the first electrode; the second electrode is arranged outside the display module; and the blood oxygen acquisition module is arranged inside or outside the second electrode. The reflective wrist oximeter delicately combines the reflective blood oxygen technology and the electrocardiograph technology, and is convenient to operate.

Description

Technical field [0001] The invention relates to the technical field of non-invasive detection, in particular to a reflection type wrist oximeter with an ECG function. Background technique [0002] The research on the non-invasive detection technology of pulse oximetry has begun in the early 20th century, and most of the oximeters now adopt the transmission detection method, which places the light-emitting tube and photosensitive sensor used for measurement in the test site. On both sides, photosensitive sensors use transmitted light to detect blood oxygen saturation. The transmissive method requires that the measured luminous tube and photosensitive sensor be on both sides of the test site, such as figure 1 As shown, the luminous tube 1 and the photosensitive sensor 2 are placed on both sides of the finger, so that the position of the photosensitive sensor is relatively single, which can only detect the finger and cannot detect the blood oxygen saturation of multiple parts of the...

Problems solved by technology

The transmissive method requires the measured light tube and photosensitive sensor to be on both sides of the test site, such as figure 1 As shown, the light-emitting tube 1 and the photosensitive sensor 2 are placed on both sides of the finger, so that the position of the photosensitive sensor is relatively single, and it can only detect the finger, but cannot detect the blood oxygen saturation of multiple parts of the human body; secondly, the transmissive type mostly uses finger clips Type measurement, to a certain extent, causes the user to feel oppressed, wears it for a long time, affects blood circulation, causes measurement errors, and has certain limitations in application

[0003] At present, the ECG measurement adopts the solution of connecting the lead wire to the host computer, such as figure 2 As shown, the electrode 3 is connected to the host through the wire 4. Due to the long cable and large internal resistance, external interference will be introduced, which will affect the effect of the electrocardiogram. Due to the large number of connectors, the connection reliability is poor, and mechanical failures are prone to occur.

[0004] There is a transmissive blood oxygen ECG integrated machine in the prior art, but there are defects in the transmissive blood oxygen method and ECG measurement method at the same time, and it is inconvenient to carry and use
