A heart rate detection apparatus includes a signal acquisition device for acquiring an intra-aural vibration wave signal and converting the intra-aural vibration wave signal into an intra-aural vibration electrical signal; and an arithmetic processing device for processing the intra-aural vibration electrical signal by computing to generate heart rate information. In the prior art, the heart rate detection apparatus cannot accurately and reliably detect the heart rate information due to the weak optical signal detected by a sensor. The heart rate detection apparatus acquires the intra-aural vibration wave signal to obtain the heart rate information, thus enabling the apparatus to accurately and reliably detect heart rate information.

Heart rate detection apparatus

Disclosed is a fingerstall oximeter comprising an upper housing (), a middle housing (), a lower housing () and a detection unit. The upper housing (), the middle housing () and the lower housing () are connected in turn. The lower housing () is made of silica gel, and a finger accommodating chamber () for accommodating a finger to be measured is formed between the opposed surfaces of the lower housing () and the middle housing (). The fingerstall oximeter has high measurement accuracy and small volume, and is easy to disassemble and carry.

There is provided a fingertip oximeter that has a plurality of display modes which are presented sequentially in a circulating way, allowing users to easily observe a measurement result from any of surrounding directions. The present invention makes users to be able to observe a measurement result of the fingertip oximeter from any of surrounding directions, without the need of bending his/her finger. Thus, any partial occlusion of the arterial blood capillary can be avoided, so that strength of the pulse will not decrease, and strength of the signal will not be affected. As a result, the precision of the measurement is improved.
