Problems solved by technology

When the ambient light is received by the photocell in the probe, it will affect the measurement accuracy of blood oxygen saturation
[0003] There is a shortcoming of the traditional soft finger cot probe with a long opening on the closed end, that is, when measuring, the opening on the closed end is often enlarged by the fingers, which causes ambient light to enter the soft probe from the opening. In the finger cot, it affects the light signal received by the photocell, thus affecting the accuracy of the measurement

Abstract

The invention discloses a soft finger stall blood oxygen probe which comprises a soft finger stall body. One end of the soft finger stall body is provided with a first opening for a human finger to be inserted therein and a containing cavity communicated with the first opening, extending to the other end of the soft finger stall body and used for containing the human finger. The other end of the soft finger stall body is provided with a second opening communicated with the containing cavity. The soft finger stall body extends out of the second opening to form a light shielding part. A blood oxygen detection sensor is arranged in the side wall of the containing cavity and comprises a light-emitting unit and a receiving unit. A plurality of wire penetrating holes are formed in the soft finger stall body. Core wires in a connecting wire enter the soft finger stall body and then penetrate through the wire penetrating holes to be connected with the blood oxygen detection sensor. The soft finger stall blood oxygen probe is reasonable in structural design; by means of a soft body structure, human tissue is prevented from being hurt; the interference of environment light to measurement of the finger stall type blood oxygen sensor can be effectively reduced, the measurement accuracy is greatly improved, and the ventilation effect can not be influenced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a soft finger cuff blood oxygen probe. Background technique [0002] The blood oxygen probe is used in conjunction with the monitor to measure the blood oxygen saturation of the patient. The blood oxygen probe contains a light-emitting element and a photocell element. The light emitted by the light-emitting element passes through the human finger, is received by the photocell element, and is converted into an electrical signal and transmitted to the monitor for a series of conversions to measure the blood oxygen saturation in the human blood. When the ambient light is received by the photocell in the probe, it will affect the measurement accuracy of blood oxygen saturation. [0003] There is a disadvantage of the traditional soft finger cot probe with a long opening on the closed end, that is, when measuring, the opening on the closed end is often enlarged b...
