The reflection type oximetry-electrocardiograph integrated machine comprises a blood oxygen acquisition module, an electrocardiographic acquisition module, a processing module and a display module, wherein the blood oxygen acquisition module is used for acquiring pulse blood oxygen data and comprises a light emitting driver, a light emitting tube and a photosensor, the light emitting driver is used for driving the light emitting tube, the light emitting tube and the photosensor are arranged on the same side of a tested part, an included angle with a predetermined angle is formed between the light emitting tube and the photosensor, and the photosensor acquires data through receiving the reflected light of the tested part; the electrocardiographic acquisition module is used for acquiring electrocardiographic signals; the processing module is connected with the blood oxygen acquisition module and the electrocardiographic acquisition module and used for processing the pulse blood oxygen data acquired by the blood oxygen acquisition module and the electrocardiographic signals acquired by the electrocardiographic acquisition module; and the display module is connected with the processing module and used for displaying the information processed by the processing module to a user. The reflection type oximetry-electrocardiograph integrated machine smartly integrates reflection type oximetry technology and electrocardiograph technology, and is simple for operation.

Description

technical field [0001] The invention relates to the technical field of non-invasive detection, in particular to a reflective blood-oxygen ECG integrated machine and a testing method thereof. Background technique [0002] The research on the non-invasive detection technology of pulse oximeter has already begun in the early 20th century. Now most of the oximeters adopt the transmission detection method. On both sides, photosensitive sensors use transmitted light to detect blood oxygen saturation. 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 c...

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 above transmissive blood oxygen method and ECG measurement method at the same time, and it is inconvenient to use
