Device for measuring finger pulse blood oxygen

Abstract

The invention discloses a device for measuring finger pulse blood oxygen, comprising an upper shell kit and a lower shell kit which are provided with soft silica gel finger pads, and the soft silica gel finger pads in the upper shell kit and the lower shell kit are matched to form a semi-sealed accommodating cavity. The device is characterized in that the soft silica gel finger pads in the upper shell kit and the lower shell kit are provided with optical windows at corresponding positions; the optical windows and the soft silica gel finger pads are integrated into a whole, and a detachable power supply assembly is installed on the lower shell kit. Compared with the prior art, the invention has the advantages that a battery are convenient for assembling and disassembling because an insertion-type power supply assembly capable of loading the battery is adopted, and the damage prevention performance of the measuring device is enhanced; and because a process of integrally forming the transparent silica gel optical window and a soft silica gel finger pad mold is also utilized by the device, the manufacturing process is simple, the consistency of a product is improved and the comfort degree of placing a finger during measuring is increased.

Description

technical field [0001] The invention relates to a measuring device for the purpose of diagnosis, in particular to a finger-type pulse oximetry device capable of measuring blood oxygen saturation and pulse rate. Background technique [0002] The finger pulse oximetry device is an integrated portable measuring instrument for non-invasive detection of blood oxygen saturation and pulse rate. During monitoring, the measuring device is clipped on the patient's finger to obtain the patient's pulse and blood oxygen saturation. clinical data. This kind of equipment is small in size, easy to carry, simple to use, and has a high degree of market acceptance. At present, there are various forms of finger-type pulse oximetry devices in China. Patent CN200610144965.3 describes a kind of protrusion or depression on the side of the shell as a mark, which is convenient for marking the correct measurement position; Chinese patent application number is CN200720194193.4, which describes a meth...

AI Technical Summary

Problems solved by technology

Most of the existing products use glue to encapsulate the chamber where the light source and photoelectric sensor is placed on the silicone finger pad, which makes the manufacturing process of the finger pulse oximetry device complicated and the consistency is not good

At the same time, most of the domestic products adopt the battery box structure, and the battery is placed in the battery box inside the finger pulse oximetry device, which makes the installation of the battery inconvenient and the damage prevention of the measuring device deteriorates; it can be seen that the existing technology still exists. Defects, to be improved and developed
