Surrounding scanning type longitudinal displacement multi-point sampling high-precision finger clamping oximeter

Abstract

The invention discloses a surrounding scanning type longitudinal displacement multi-point sampling high-precision finger clamping oximeter. The oximeter comprises a finger clamping device and a multi-point sampling device; the finger clamping device is used for clamping a finger of a patient, and adjusting the size of an opening of a finger clamping area, used for clamping the finger of the patient, of the finger clamping device; the multi-point sampling device comprises a mounting frame, a rotating mechanism, a mounting mechanism, a first driving mechanism, a second driving mechanism, a distance sensor arranged on the mounting frame and a blood oxygen measuring element arranged on the mounting mechanism; the rotating mechanism is used for driving the mounting frame to rotate; the first driving mechanism is used for driving the blood oxygen measuring element to move close to the finger of the patient in the radial direction of a mounting sleeve; the second driving mechanism is used for driving the blood oxygen measuring element to move in the axial direction of the mounting sleeve; the distance sensor is used for sensing the length of the finger, stretching into two finger clamping plates, of the patient; and the blood oxygen measuring element is used for measuring blood oxygen of the finger of the patient.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to the field of finger clip oximeters. Background technique [0002] With the development of the times, people pay more and more attention to their health. They often do some physical examinations, and the oximeter has become more common. The main measurement indicators of the oximeter are pulse rate, blood oxygen saturation, Perfusion index and blood oxygen saturation are one of the important basic data in clinical medicine, which can be used to judge the physical condition of the examiner. The existing oximeters are generally finger clip type, and there are some shortcomings, such as: 1.

[0002] With the development of the times, people pay more and more attention to their health. They often do some physical examinations, and the oximeter has become more common. The main measurement indicators of the oximeter are pulse rate, blood oxygen saturation, Perfusion index and blood oxygen saturation are one of the important basic data in clinical medicine, which can be used to judge the physical condition of the examiner. The existing oximeters are generally finger clip type, and there are some shortcomings, such as: 1. If the hand of the tester shakes too much, it may cause the oximeter to fall, and the existing finger clip oximeter generally clamps the fingers by means of torsion springs, without any other measures. Measures to adapt to fingers of different thicknesses, resulting in unstable clamping by thin-finger detectors, and excessive clamping by thick-finger detectors to form pinch marks; 2. The sampling point is fixed, and the existing oximeter is used to detect fingers The position of the blood oxygen measuring element is fixed, and the medical staff and the tester cannot observe the internal condition of the oximeter through the shell of the oximeter. affect blood oxygen measurement results; therefore, the present invention proposes a high-precision finger clip oximeter with surround scanning longitudinal displacement multi-point sampling, which can adapt to different finger thickness detectors. The point sampling method measures the pulse rate, blood oxygen saturation, and perfusion index of the examiner. On the one hand, it makes the measurement results more accurate. On the other hand, there are multiple sampling points, which can avoid cocoons or other thick skin from affecting the blood oxygen measurement results. Impact
