| 20110190602 | METHOD FOR MEASURING BLOOD OXYGEN AT A FINGER AND FINGER-CLIPPED OXIMETER - The present invention provides a method for measuring blood oxygen at a finger, comprising the following steps: | 08-04-2011 |
| 20100331635 | Finger-Clipped Oximeter with Finger Pressed Plate - The present invention discloses a finger-clipped oximeter comprising: an upper case ( | 12-30-2010 |
| 20100317944 | Rocker-Chute Type Finger-Clipped Oximeter - The present invention discloses a finger-clipped oximeter comprising an upper case ( | 12-16-2010 |
| 20100198028 | Soft Gum Fingerstall Oximeter Without Pivot Structure - The present invention discloses a soft gum fingerstall oximeter without pivot structure, the soft gum fingerstall oximeter comprises a soft gum fingerstall which can wraps around a finger closely with variations of the profile of the finger and causes a clamping force distributed on the clamped portion of the finger uniformly. An emission circuit board and a reception circuit board are provided in the soft gum fingerstall. The soft gum fingerstall of the oximeter is enclosed, which can shield light entering from a side. | 08-05-2010 |
| 20100160753 | WRIST BLOOD PRESSURE MONITOR WITH AN OXIMETER - A wrist blood pressure monitor with an oximeter, characterized in that the wrist blood pressure monitor and the oximeter are arranged on the same base; the length direction of the wrist blood pressure monitor is parallel to the width direction of an armband; and a finger hole of the oximeter is oriented to be vertical to the width direction of the armband. The wrist blood pressure monitor with the oximeter according to the present invention can measure the blood pressure and the blood oxygen at the same time, so that the user can not only operate conveniently, but also acquire more accurate measuring results; or the blood pressure and the blood oxygen are measured independently, so that the user can operate in great convenience. | 06-24-2010 |
| 20100036218 | FINGERTIP BLOOD OXYGEN SATURATION MEASURING APPARATUS - A blood oxygen saturation measuring apparatus comprising an upper shell, a lower shell, and an elastic restoring structure, characterized in that a mark is arranged on a lateral side surface of the upper and/or the lower shell; and the mark is provided to be in alignment with the vertical position of a photoelectric sensing chip which is arranged inside the shell. According to the present invention, the humanized mark is adopted, which can observe the measured position of the measured finger. Even if in the case of weak light environment or a lazy eye user, the accurate and reliable blood oxygen saturation data can be acquired. | 02-11-2010 |
| 20090137891 | PORTABLE ELECTROCARDIOGRAPH WITH A NEUTRAL ELECTRODE - A portable electrocardiograph, characterized in that a clamping cover which tends to close automatically is provided on one end of a housing; a finger hole is provided between the clamping cover and the housing; a lower half of the inner wall of the finger hole is defined on the housing; an upper half of the inner wall of the finger hole is provided on the clamping cover; the lower half of the inner wall is provided with a first electrode; the other end of the housing is provided with a second electrode; and the back face of the housing is provided with a third electrode, in which the first electrode or the third electrode is a neutral electrode. According to the present invention, at least one portion of at least one of the middle finger, the so-called ring finger, and the little finger of the user's hand for grasping the electrocardiograph can contact the neutral electrode, such that the error of the measured result caused by electrical potential fluctuation on the measured person's body can be eliminated. | 05-28-2009 |
| 20080242959 | Fingertip Oximeter and a Method for Observing a Measurement Result Thereon - 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. | 10-02-2008 |
