Referring to fig. 1 and 2, in one embodiment, a nose-clip type parameter detecting probe includes a first clip body 10, a second clip body 20, a parameter detecting assembly 30, an elastic member 40, and a connecting cable 50.

The first clamp body 10 is provided with a first detection end 11, a first handheld end 12 and a first butt joint part 13, a rotating part 14 is arranged on the first butt joint part 13, and the rotating part 14 is a spherical convex structure which is distributed by protruding out of the surface of the first butt joint part 13; the second clamp body 20 is provided with a second detection end 21, a second handheld end 22 and a second butt joint part 23, the second butt joint part 23 is provided with a shaft cavity 24, the cross section of the shaft cavity 24 is in a strip shape extending along the opening and closing direction of the first clamp body 10 and the second clamp body 20, and the shaft cavity 24 adopts a blind hole or through hole structure; the rotating parts 14 are positioned at both sides of the shaft cavity 24 and are rotatably installed in the shaft cavity 24 in an inserting manner.

By the structural cooperation of the rotating portion 14 and the shaft cavity portion 24, on one hand, the first clip body 10 and the second clip body 20 can jointly form a clip body structure, so that when in use, one of the first clip body 10 (at least including the portion of the first detection end 11) and the second clip body 20 (at least including the portion of the second detection end 21) is inserted into the nasal cavity of a user, and the other is placed outside the nasal cavity of the user, so that the nasal wings can be clamped from the inner side and the outer side through the cooperation of the first clip body 10 and the second clip body 20 (especially the cooperation of the first detection end 11 and the second detection end 21).

On the other hand, the rotating part 14 can move in the opening and closing direction in the shaft cavity 24, so that the first butt joint part 13 and the second butt joint part 23 can be away from or close to each other in the opening and closing direction, and when the thicknesses of the nose wings of the user are different, the distance between the first detection end 11 and the second detection end 21 can be automatically adjusted by overcoming the elastic force of the elastic piece 40, so that the probe can adapt to different patients, and the universality of the probe and the comfort of the user are improved.

In some embodiments, the rotating portion 14 may also be a shaft-like structure or other similar functional structures distributed throughout the axial cavity 24, while ensuring the ability or condition of the rotating portion 14 to rotate relative to the axial cavity 24 and move a certain distance in the opening and closing direction in the axial cavity 24.

In some embodiments, the first clip body 10 and the second clip body 20 may be further provided with an avoidance gap a, which is respectively located at the root of the first detection end 11 and the root of the second detection end 12, and the avoidance gap a may be used to avoid the outermost edge of the nose wing, so as to reduce discomfort of the nose wing being clamped.

The parameter detecting assembly 30, as a core element of the probe for realizing the function of detecting the physiological index parameter of the human body, includes a detecting light emitting unit 31 for emitting detecting light and a detecting light receiving unit 32 for receiving the detecting light, wherein a detecting light emitting end of the detecting light emitting unit 31 is disposed opposite to a detecting light receiving end of the detecting light receiving unit 32. In one embodiment, the sensing light emitting unit 31 is installed in the first sensing terminal 11, and the sensing light receiving unit 32 is installed in the second sensing terminal 21; in other embodiments, the detecting light emitting unit 31 may be installed in the second detecting end 21, and the detecting light receiving unit 32 may be installed in the first detecting end 11.

In particular implementations, the parameter detection component 30 may be configured to, but is not limited to, ICG concentration detection, blood oxygen saturation detection, and the like, specifically:

in one embodiment, the parameter detection component 30 is configured to function as ICG concentration detection, namely: the detection light emitting unit 31 has at least three light pipes, the light pipes are used as the detection light emitting end of the detection light emitting unit 31 to enable the detection light emitting unit 31 to emit at least three kinds of detection light with different wavelengths, the number of the light pipes and the wavelength of the emitted detection light can be set selectively according to the actual situation, for example, the three light pipes can respectively emit infrared light with wavelengths of 660nm, 805nm, 940nm and the like which can penetrate through human tissues, skins, blood vessels, bones and the like; accordingly, the detection light receiving unit 32 has a matching capability or structure for receiving the infrared light emitted from the light pipe, and at the same time, can convert the light signal into an electrical signal, and finally transmit the electrical signal to the control unit through the connection cable 50.

Because ICG enters the human body from intravenous injection, the reaction speed with plasma protein is very fast, ICG is hardly deposited on the skin after entering the blood, and can not be absorbed by other tissues, hemoglobin has no obvious influence on the measurement of ICG, and the concentration of ICG and absorbance are in a linear relation, the concentration of ICG calculated by measuring the absorbance of ICG can be used as the basis for evaluating the liver reserve function; therefore, the parameter detecting unit 30 transmits the detecting light from one side of the nasal ala to the other side by emitting the detecting light with at least three different wavelengths, and the ICG concentration can be finally detected according to the judgment of the signal receiving intensity of the detecting light.

In one embodiment, parameter sensing component 30 may also be configured to have the functionality of blood oxygen concentration sensing, namely: the detection light emitting unit 31 has at least two light pipes, and the light pipes are used as the detection light emitting ends of the detection light emitting unit 31 to enable the detection light emitting unit 31 to emit detection light with at least two different wavelengths, and the number of the light pipes and the wavelength of the emitted detection light can be selected according to actual conditions, for example, the two light pipes can respectively emit 660 ± 40nm red light and 940 ± 40nm infrared light; accordingly, the detection light receiving unit 32 has a matching capability or structure for receiving the red light and the infrared light emitted from the light pipe, and can convert the light signal into an electrical signal and finally transmit the electrical signal to the control unit through the connection cable 50.

Since the amount of absorption of light of a specific wavelength by a part of tissues of a human body is constant, the light wave changes only with the pulsation of the pulse (the change of the amount of oxyhemoglobin), and when arterial blood passes through a detection site such as a nasal ala, the absorption rate of light waves such as red light decreases and the absorption rate of light waves such as infrared light increases with the increase of the amount of oxyhemoglobin; at this time, the blood oxygen saturation index of the detection site can be obtained by collection, signal conversion, and the like of the light wave. Therefore, the final blood oxygen saturation detection can be realized by utilizing the characteristics that the red light and the infrared light with the wavelengths can penetrate through the skin, the muscle, the blood vessel, the bone and the like of the detection part such as the nasal alar part and the like.

In other embodiments, the parameter detecting component 30 can also be configured to detect other human parameters as the object detecting device.

Based on the above, the nose clip type parameter detection probe takes the nose wing as a parameter detection part; firstly, after the first clamp 10 and the second clamp 20 are used for clamping the nosewings from the inner side and the outer side, the detection light emitting unit 31 and the detection light receiving unit 32 are respectively positioned at the two sides of the nosewings and are oppositely aligned, and due to natural cavities existing in the nosewings, the detection light emitting unit 31 and the detection light receiving unit 32 can be better attached to the two sides of the nosewings, so that the matching degree between the detection light emitting unit 31 and the detection light receiving unit 32 is enhanced; and the natural dark space that the nasal cavity provided can effectively avoid the interference of external light to detecting light, especially when detecting light receiving element 32 and being located the nasal cavity, the precision that more signal detection provided favorable assurance. Secondly, the nasal ala is closer to the heart, the blood flow is abundant, the blood circulation is more abundant, the detection light emitted by the detection light emitting end of the detection light emitting unit 31 can be more ideally and more sensitively received by the detection light receiving end of the detection light receiving unit 32, thereby creating conditions for realizing high-precision detection and continuous detection of human physiological index parameters such as ICG concentration and blood oxygen saturation in blood. Thirdly, since one side of the wing of the nose is a mucous membrane and the other side is a skin, the sensitivity of the reaction of the detection light emitting unit 31 and the detection light receiving unit 32 is higher.

The elastic member 40 directly or indirectly acts on the first clip body 10 and the second clip body 20, and the elastic force generated by the elastic member 40 is used to urge the first detection end 11 and the second detection end 21 to move relatively far away or relatively close to each other so as to clamp the nosewings of the user when the two are relatively close to each other.

In specific implementation, the elastic member 40 may be a spring, a torsion spring, an elastic bending member, or other similar mechanical parts that deform under an external force and recover to its original shape after the external force is removed, one end of the elastic member 40 is connected to the portion where the first clip body 10 is located (e.g., connected to the first holding end 12 or the first detecting end 11), and the other end is connected to the portion where the second clip body 20 is located (e.g., connected to the second holding end 22 or the second detecting end 12), so as to ensure that the first detecting end 11 and the second detecting end 21 can rotate relative to each other with the rotating portion 14 as a rotation axis, thereby realizing the conversion of the structural state of the first clip body 10 and the second clip body 20 that are relatively opened or closed.

The connection cable 50 has one end electrically connected to the detection light emitting unit 31 and the detection light receiving unit 32, and the other end electrically connected to a control unit (not shown) to transmit an electrical signal; the control unit can be understood as a terminal host used with the probe, and plays roles of sending, receiving, processing and the like of signals, for example, the control unit controls the detection light emitting unit 31 to emit the detection light through the connection cable 50, and controls the detection light receiving unit 32 to receive the detection light through the connection cable 50. The correlation signal is received through the connection cable 50 to obtain parameter data and the like through subsequent processing of the correlation signal. In this embodiment, the connection cable 50 may be integrally assembled with one of the first clip body 10 and the second clip body 20 according to practical situations, and more specifically, when the second clip body 20 is used as a structural part inserted into the nasal cavity of a user, the connection cable 50 may be integrally assembled with the first clip body 10 to facilitate the operation of the ICG concentration detection probe.
