specific Embodiment approach 1

[0020] Embodiment 1: The helical plastic optical fiber respiration sensor in this embodiment includes a plastic optical fiber that is macrobent into a reverse double helix and an elastic linear object; the reverse double helix plastic optical fiber is fixed to the elastic linear object at multiple points.

[0021] In this embodiment, a tensile test is carried out on the helical plastic optical fiber breathing sensor with different helical radii. While ensuring a high signal-to-noise ratio, according to the amount of light loss before and after the elastic linear object is stretched, it is found that the smaller the helical radius is, the better the light intensity before and after stretching. The more obvious the change. The fixed point between the plastic optical fiber and the elastic linear object is to avoid the separation of the plastic optical fiber and the elastic linear object during the detection process, and the specific number of fixed points can be determined by itse...

specific Embodiment approach 2

[0022] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the length T of the reverse double helix structure in the reverse double helix plastic optical fiber is 4-6 cm. The length of the elastic linear object in the natural state is W, and T+6cm>W≥T. Other steps and parameters are the same as in the first embodiment.

[0023] T is the length of the reverse double helix without external force.

specific Embodiment approach 3

[0024] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the elastic linear object is an elastic rope or a helical linear expansion and contraction object. Other steps and parameters are the same as in the first or second embodiment.

[0025] In this embodiment, the helical linear retractable object is a telephone receiver wire or a spiral hair coil.

[0026] In this embodiment, the radius of the reverse double helix structure of the plastic optical fiber matches the radius of the helical linear expansion and contraction object.

Abstract

The invention discloses a spiral plastic optical fiber respiration sensor and a preparation method thereof, and relates to an optical fiber respiration sensor and a preparation method thereof. The spiral plastic optical fiber respiration sensor comprises a plastic optical fiber and an elastic linear object, wherein the plastic optical fiber is macroscopically bent into reverse double helixes; and the reverse double-helix plastic optical fiber is fixed on the elastic linear object in a multi-point manner. The preparation method of the sensor comprises the following steps: macro-bending the plastic optical fiber into a reverse double-helix structure, and then fixing the reverse double-helix plastic optical fiber on the elastic linear object in a natural state in a multi-point manner. The optical fiber respiration detection device comprises a laser, a photoelectric detector, an acquisition card and a computer, and further comprises the spiral plastic optical fiber respiration sensor. The spiral plastic optical fiber respiration sensor is good in long-term repeatability and reliability.

Description

technical field [0001] The invention relates to an optical fiber breathing sensor and a preparation method thereof. Background technique [0002] At present, the most common inspection method in hospitals is to use a ventilator to measure respiratory parameters. Although the above equipment is accurate, its structure is complex and expensive, and each inspection only takes a few minutes. According to Dr. Suneet Mittal, a cardiologist at Valley Hospital in New Jersey, a few minutes per examination is not enough, and it can easily lead doctors to make medical decisions based on "incorrect data obtained from short-term measurements." SUMMARY OF THE INVENTION [0003] In order to overcome the problem that each inspection time of the existing breathing inspection method is short, only a few minutes, and it is easy to cause doctors to make medical decisions based on "wrong data obtained by short-term measurement", the present invention provides a spiral-type plastic optical fibe...
