Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and more particularly to a detection device and a urinary catheter. Background Technology
[0002] Currently, cellular respiration capacity is a crucial indicator of human aerobic metabolism, and many critically ill patients suffer severe impairment of their metabolic capacity. When the body experiences overall oxygen deficiency, it prioritizes oxygen delivery to vital organs, such as the brain and heart. Simultaneously, the oxygen supply to non-vital organs decreases rapidly. Therefore, when metabolism is insufficient, detecting aerobic metabolism in non-vital organs is more sensitive than in vital organs.
[0003] However, current medical technology has limited capabilities in detecting the metabolic capacity of human cells. Existing medical equipment can only detect the epithelium of the arm and cannot provide continuous dynamic monitoring.

The detection device 400 is disposed at the third port of the connecting pipe 100. The detection device 400 includes a third optical fiber 410, which is disposed on the propagation optical path of the first detection light 220 and the second detection light 320, thereby transmitting the first detection light 220 and the second detection light 320 to the target detection position, transmitting the first reflected light 420 to the first optical fiber 210, and transmitting the second reflected light to the second optical fiber 310.

A first receiving sub-optical fiber is disposed in the third space, and the first receiving sub-optical fiber transmits the first detection light from the first detection sub-optical fiber and the second detection light from the second detection sub-optical fiber.

[0065] Figure 4 This is a schematic partial structural diagram of an aerobic metabolism monitoring device provided in an embodiment of this application. In some examples, reference is made to... Figure 4 In the second space, portions of the first and second detection sub-fibers are arranged adjacent to each other. In the third space, adjacent receiving sub-fibers are spaced apart, with portions of the first detection sub-fibers positioned between adjacent receiving sub-fibers and portions of the second detection sub-fibers positioned within adjacent receiving sub-fibers. A portion of the first detection sub-fibers in the third space is adjacent to the first detection sub-fibers in the second space, and a portion of the second detection sub-fibers in the third space is adjacent to the second detection sub-fibers in the second space.
[0066] For example, the first space is Figure 4 The third space is the outer ring area, and the second space is the middle ring area. Detection beams of the same wavelength are arranged adjacently, which facilitates the transmission of the detection beams to the target detection position, thereby improving detection accuracy and effectiveness.
[0067] In some examples, the third optical fiber includes a third detection sub-optical fiber and a third receiving sub-optical fiber, with the third receiving sub-optical fiber surrounding the third detection sub-optical fiber.

Figure 5 The light output direction of the third optical fiber 410 intersects with the light propagation direction of the third optical fiber 410.
[0070] For example, refer to Figure 5The third optical fiber 410 forms an angle α between its light-emitting direction and its light-propagating direction, so that the first detection light 220 and the second detection light 320 transmitted in the third optical fiber 410 can be emitted at an angle to the target detection position.
[0071] In some examples, the light output direction of the third fiber can be perpendicular to the light propagation direction of the third fiber.
[0072] In some examples, the angle between the light output direction of the third fiber and the light propagation direction of the third fiber is less than or equal to 90°.
[0073] In some examples, the tilt angle of the third fiber is 30°.
[0074] In some examples, the outer wall surfaces of adjacent sub-fibers are set to be tangent.
[0075] For example, a tangent setting can improve the connection stability of optical fibers.
[0076] In some examples, reference Figure 5 At least a portion of the third optical fiber 410 is bent, and the third optical fiber 410 includes a bending angle θ, the angle of which is less than or equal to 120°.
[0077] For example, the third optical fiber is bent to form an angle, so that the detection light is transmitted to the target detection position.
[0078] In some examples, the first detection sub-fiber can be used to monitor the content of reduced coenzyme I (NADH, Nicotinamide adenine dinucleotide) in the tissue, and the second detection sub-fiber can be used to monitor blood oxygenation parameters in the tissue, such as tissue oxygen saturation (TOI) and tissue hemoglobin concentration index (THI). Since the relationship between THI and NADH concentration is relatively sensitive, blood oxygenation parameters can be detected through the second detection sub-fiber, and the modified Beer-Lambert law can be used to simultaneously monitor total tissue hemoglobin and correct the monitored NADH.
[0079] In some examples, the modified Beer-Lambert law is A = lg(I1 / I2) / kb, where A is the absorbance, I1 is the incident light intensity, I2 is the reflected light intensity, K is the molar absorptivity, and b is the thickness of the absorption layer.
