A kind of probe preparation process

Abstract

The invention discloses a probe preparation technology, comprising: welding a USB male joint with the front end of a board-side rigid circuit board; welding a flexible circuit board to the tail end of the board-side rigid circuit board; then welding in sequence a light emitting diode and two photosensitive tubes onto the upper surface of the flexible circuit board for a flexible circuit board component; taking out a medically applied double-sided adhesive tape which comprises an upper layer of wax paper, a middle layer of glue, and a lower layer of wax paper; cutting for the profile of the flexible circuit board on the upper layer of wax paper in advance; tearing off the profile of the flexible circuit board; adhering the prepared flexible circuit board component along the profile; removing the remaining upper layer of wax paper; taking out the medically applied foam tape which includes an upper layer of non-woven fabrics, a middle layer of medical foam, and a lower layer of wax paper; removing the lower layer of wax paper; aligning the foam tape and the profile of the medically applied double-sided adhesive tape along one side of a tool; pressing tight and fixing them; sleeving from the USB male joint the board-side protection sheath; and filling seal materials between the board-side rigid circuit board and the board-side protection sheath.

Description

technical field [0001] The invention belongs to the technical field of medical device preparation, and in particular relates to a probe preparation process. Background technique [0002] Near Infrared Spectroscopy (NIRS) is a physiological parameter detection technology that has gradually emerged in the past 20 years. Its core detection indicators are tissue oxygen saturation (TissueOxygenIndex, TOI) and tissue hemoglobin concentration index ( Tissue Hemoglobin Index, THI). The near-infrared tissue blood oxygen parameter non-destructive monitor (hereinafter referred to as the oximeter) injects light of three different wavelengths into the tissue under test, and obtains the absorption of light by the tissue by measuring the intensity of the outgoing light, and then undergoes a series of solutions. Finally, a series of tissue blood oxygen parameters such as the measured tissue oxygen saturation (TOI, %) and tissue hemoglobin concentration index (THI) are obtained. The oximet...

Problems solved by technology

The shortcoming of adopting above-mentioned structure to prepare probe is:

[0004] 1. Traditional circuit boards have relatively poor performance, low reliability and poor stability, and cannot meet the predetermined reliability and stability requirements;

[0005] 2. The pass rate of production probes is relatively low;

[0006] 3. The mass production efficiency of the probe is low
