Description
Technical Field
The invention belongs to the field of design of microcirculation monitoring, and particularly relates to a detecting body with a hook type sensor structure and a tongue bottom microcirculation detecting device.
Background
Microcirculation refers to the circulation of blood between the oligodynamic and the venules. The most fundamental function of the blood circulation is to perform the exchange of substances between blood and tissues, which is performed in the microcirculation part. In recent years, microcirculation has been considered the ultimate destination of the cardiovascular system responsible for the supply of oxygen to tissues by red blood cell transport, and is considered the primary "responsible" for tissue health because it is a crucial factor affecting tissue oxygen supply. The ultimate goal of fluid therapy is to improve perfusion at the level of microcirculation. Only fluid therapies that improve microcirculation blood flow and cause correction of clinical parameters that reflect hypovolemia (e.g., tachycardia, oliguria, hyperlactacidosis, or low central venous oxygen saturation) will have a positive impact on the patient's condition.
The tongue bottom microcirculation has been emphasized in clinical application because of its convenience and non-invasive property. Currently, the microcirculation monitoring means used clinically mainly include orthogonal polarization spectroscopy, lateral flow dark field imaging, laser doppler imaging, near infrared spectroscopy, pulse oximetry monitoring, laser scanning confocal microscopy, and the like. The first generation of Orthogonal Polarization Spectroscopy (OPS) and hand-held electron microscopy opened a new era of microcirculation monitoring by studying microcirculation of exposed tissues and organs of the human body. Second generation lateral flow dark field imaging (SDF) is currently the most widely used means for monitoring microcirculation changes in clinical studies [ Milstein DM, Lindeboom JA, Inc. C. internal digital Stream Data Field (SDF) imaging used in a diagnostic model for the diagnosis of microcirculation and quantification of microbial coronary regeneration and surrounding health in the same clinical routine: a pilot decision [ J ] Arch biological 2010, 55(5):343-349 ]. The third generation is a handheld dark field microscope based on Incident dark field imaging mode (IDF), which is a successor to lateral flow dark field imaging (SDF), with the advantages of improved optical resolution. The SDF optically isolates incident light from reflected light, while the IDF illuminates the entire monitoring area in a hemoglobin absorption dark field manner, so that the IDF provides an advantage of increasing the field area of view.
The microcirculation monitoring means needs an operator to hold the monitoring probe in hand when working, the monitoring probe is accurately attached to the tongue of a patient, green light with the wavelength of about 530nm is emitted by the light emitting diode, and after red blood cells at the bottom of the tongue absorb the green light, dynamic information of the capillary vessel is collected through a dark field imaging technology of the charge coupled device, so that information such as blood vessel density, blood flow velocity and the like is obtained. However, the operator cannot avoid physiological shake, which causes the lens to shake relative to the tongue, and a light person cannot obtain a stable image; the serious one can affect the blood flow rate and even injure the tongue and contaminate the probe head. Moreover, holding the instrument for extended periods of time for continuous monitoring can be painful to the operator. Although the problem can be alleviated by time-sharing and time-sharing monitoring, the comparison and observation of the blood vessels at the same position can not be ensured during the secondary monitoring, and the accuracy of calculating the blood vessel density and the blood flow speed is influenced.
For the problem of phase plane movement caused by the shaking of the probe relative to the tongue, an automatic focusing method proposed in patent document with publication number "CN 207575140U" and name "a microcirculation imaging device" can be adopted to obtain a clear image, and an automatic focusing algorithm is triggered according to the contrast of the obtained image, so as to input an instruction to a lens controller and adjust the lens distance. In addition, the pressure sensor proposed in patent document with publication number "CN 206473308U", entitled "image stabilization and probe pressure control device for handheld micro-circulation monitor", can ensure that the probe and the tongue are attached to reach a more ideal state, and avoid the imaging confusion caused by too far distance between the probe and the tongue and the blood vessel extrusion caused by too close distance. However, these monitoring devices cannot be used in the same area in clinical practice, and continuous comparative observation is performed, so that the calculated parameters such as blood flow rate are inaccurate. In order to solve the problem, patent application documents with the publication number of "CN 105662388A" named as "rapid and repeatable positioning microcirculation shock monitor and monitoring system and method" provide that under a low-power large visual field, the blood vessels near the large blood vessels which are easy to observe are numbered, the most obvious large blood vessels are fixed at the center of a screen by using a cross line of a computer screen acquisition window, and when the monitoring is carried out for the second time, a rough area is found, and the number can correspond to the previously tracked blood vessel images.
However, these monitoring methods are also based on hand-held operation, physiological jitter being unavoidable. Moreover, the volume of the probe is large, and the comfort of the patient is not good when the patient is contained at the bottom of the tongue. Although the imaging quality and the data accuracy are improved, the tongue bottom of a patient is easy to be stressed; for doctors or operators, the probes are held by hands for a long time, so that the operation is very inconvenient, and continuous microcirculation detection cannot be realized.

Detailed Description
The present invention provides a tongue fundus microcirculation probe, which is further described in detail with reference to the accompanying drawings and the specific embodiments. Advantages and features of the present invention will become apparent from the following description and from the claims.
Because the volume of a front-section detection part is large and the whole detection instrument is heavy, the conventional microcirculation monitoring handheld equipment cannot realize continuous long-term monitoring; the requirement on an operator is high, and the detecting head body is close to the tongue bottom and is easy to extrude mucosa and subcutaneous blood vessels; the body of the probe is far away from the tongue bottom, so that the quality of collected video is influenced; the invention provides a portable detector capable of continuously monitoring microcirculation at the bottom of a tongue for a long time, and realizes continuous monitoring and analysis of the microcirculation at the same part.
Optical fibers play an important role in the fields of medical imaging, sensing, laser therapy, and the like due to their excellent signal transduction capabilities. Among them, the image guidance system using the endoscope is most widely used: according to the total internal reflection of the light at the interface of the fiber core and the cladding, the light is transmitted from the outside to the inside of the body, and the affected part is illuminated; and reflected light on the surface of the tissue is collected by the probe body and is transmitted to a rear processing system through the optical fiber, so that endoscopic imaging is realized. Based on this, the tongue bottom microcirculation probe in this embodiment adopts optical fiber to conduct optical signal, and separates the probe body from other working units of the microcirculation monitoring system. During operation, as long as the miniature probe body that has optic fibre with the parcel hangs on user's tooth, ensures that the relative tongue bottom of probe body is fixed, and separately sets up with the probe body about instruments such as signal image processing to optic fibre is connected, compares handheld monitoring instrument nimble more light.

In this example, the tubular body of the probe body 1 may be integrally formed or may be separately formed from the front end portion, the middle section, and the rear end portion. The front end part, the middle section part and the rear end part can be integrally formed into a hook-shaped structure, and when the medical adhesive tape is used, the medical adhesive tape is hung on teeth (such as teeth, gums and the like) of a user and then fixed in position through the medical adhesive tape.
The front end of the detecting head body is provided with a microcirculation signal collector 2, the inside of the detecting head body is provided with an optical fiber, and the optical fiber is optically connected with the microcirculation signal collector and used for conducting optical signals. The microcirculation signal collector 2 generally comprises a light source and a light receiving device of an imaging receiving channel.
The light source may be for providing incident light at a wavelength λ, where λ > 0. Specifically, "light" emitted by the light source includes, but is not limited to: pulsed xenon arc or lamp, mercury arc or lamp, halogen Light or lamp, tungsten arc or lamp, laser Diode or Light Emitting Diode (LED for short). "light" can also be classified as coherent or incoherent light, and thus the light source can be either a coherent or incoherent light source. In one embodiment, the wavelength λ of the incident light provided by the light source is determined by the absorption spectra of hemoglobin and deoxyhemoglobin in the microcirculation. In the absorption spectra of hemoglobin and deoxyhemoglobin, 420nm (nanometers), 550nm and 800nm are equal absorption peaks of hemoglobin and deoxyhemoglobin. The wavelength of the incident light provided by the light source 102 in this embodiment is 530nm, but is not limited to 530nm, and may also be 540nm or 550 nm.
The light source is not only a single light source, but also a plurality of light source components, in this case, the light source can be disposed on the side wall of the front end of the probe body. I.e., the light source is disposed at the end of the end in contact with the base of the tongue, slightly spaced from the contact portion of the base of the tongue, primarily to facilitate the projection of the illumination beam provided by the light source onto the tissue surface, including the base of the tongue.
It is common practice to provide the housing of the probe body 1 with a plurality of holes, in which light source modules are respectively mounted, and to set the light source modules that can provide the illuminating beams at an angle to the horizontal. Several processing schemes are possible with this example. For example, the light sources of the light source assembly are transversely or longitudinally arranged on the side wall of the front end of the detecting head body 1, and according to the difference of tongue bottoms of different people, the system can control the light sources at different positions to work, so that the universality of the detecting head is improved. As another example, the angle that the light source assembly makes with the horizontal may be adjustable, and during the microcirculation detection, the medical operator may set the angle to be adjusted so that the illumination angle of the provided illumination beam is adjustable. The light penetration depth can be related to the incident angle of the light, so that microcirculation images with different depths in human tissues can be obtained by adjusting the incident angle of the incident light.
It should be noted that the light source mentioned in this example is a relatively large concept, and includes not only a narrow light source but also a broad light source. The light source in the broad sense means a light processing part having a better effect of incident light by including not only a light source generating part for providing an illumination light beam but also a light processing part for performing a secondary processing on the generated light beam. Such as: the device also comprises a condenser lens and the like which are used for converging and collimating the generated illumination light beams.
The lens structure (not shown) needs to satisfy the condition that the diameter of the light spot after the received light is converged is smaller than the inner diameter of the flexible optical fiber.
Jianzhao et al proposed a new generation of Fiber Imaging system based on deep Learning and Anderson local area fibers (Zhao J, Sun Y, ZhuZ, et al deep Learning Imaging through flux-Flexible Glass-Air distributed Fiber [ J ]. ACS Photonics, 2018.). The system has simple structure, low cost and extremely high robustness. The optical fiber imaging system can transmit the image of the defect-free cells at high speed and real time at 20Hz under a non-relevant broadband light source. Moreover, the system can still maintain high-speed and high-quality cell image transmission under the mechanical bending disturbance and severe temperature change, and the imaging depth can be extended to be about 4mm under the lens-free state. The invention can also directly adopt the optical fiber imaging system, and the system adopts the Anderson local optical fiber which comprises an incoherent broadband illumination light source, a power-adjustable operation laser light source, an optical fiber wavelength division multiplexer, an optical fiber side-throwing coupler, the Anderson local optical fiber with an annular waveguide and a camera system. The Anderson local area optical fiber is directly installed in the probe body, and under the condition, the microcirculation signal collector and the subsequent optical fiber part can be omitted, and the front end part of the optical fiber is directly bent into a hook shape.
The lens structure can be arranged newly, for example, only one plano-convex lens is directly adopted, the distance between the laser used as the light source and the lens is adjusted, and light spots smaller than the inner diameter of the flexible optical fiber can be observed on the other side. In addition, if the spot quality of the focused spot is required, a diaphragm can be added to filter out stray light. In addition, the laser is placed at the focal length of the lens, and is refracted by the lens to form parallel light, and then the diaphragm is added. The above disclosure is only an example, and there are many possible implementations of the lens structure, and this example is not intended to limit the present invention.
At least one section of the probe body 1 is bent into a hook shape to form a hook type structure, when tongue fundus microcirculation detection is carried out, the front end part of the probe body is contacted with tongue fundus tissues, and a tongue fundus microcirculation detection body is positioned and arranged on a tooth body matched with the tongue fundus tissue pre-detection position through the hook type structure; the hook part of the hook type structure is a flexible structure, so that the hook width of the hook part can be adjusted to be matched with the tooth body of a user, or the position of the hook part at the position of the probe body can be adjusted to adjust the distance between the front end part of the probe body and the tongue bottom tissue.
The invention has an implementation scheme that the front end part and the middle section part of the probe body 1 are respectively used as a hook tip and a hook end of a hook, and the front end part and the middle section part of the probe body form a hook type structure. The other realization scheme is that the middle section of the probe body is in a hook shape to form a hook type structure, so that the front end part of the probe body is in a horizontal shape, and the rear end of the probe body can also be in a horizontal shape, thereby being convenient to hold and position.
When the pre-detection position of the tissue of the tongue bottom is determined, the tooth body matched with the position of the tissue of the tongue bottom can be found. The invention not only realizes the accurate positioning of the detection position through the position of the tooth body. The normal dentition of a healthy adult comprises 32 permanent teeth which are divided into four areas, namely upper, lower, left and right areas, and is divided into 16 pairs of incisors, cuspids, double cuspids (premolars) and molars according to the shapes and functions of the teeth. The left and right paired teeth of the same name have the same anatomical morphology. The tooth body comprises three calcified hard tissues of enamel, dentin and cementum and a pulp cavity for accommodating soft tissues of dental pulp. Each tooth body consists of a crown, a neck and a root. For example, when a patient performs the tongue bottom microcirculation detection, the position of a certain cuspid of the detection hanging note can be recorded, and the tongue bottom microcirculation monitoring detection is performed next time, so that the tongue bottom tissue pre-detection position of the last detection can be conveniently obtained. If the hanging marks are on the same cuspid, the possibility of detecting the pre-detection position of the same tongue bottom tissue is greatly enhanced, so that the tooth body not only can be used for fixing, but also can be used for marking the position. In addition, the tooth-hanging plate can be directly hung on a dental crown, and can also be hung on a dental root of an old person or the like when the old person or the like does not have teeth.

Specifically, the middle portion of the probe body may be a flexible body with a certain bending degree, for example, a corresponding material may be adopted to make it have the characteristic. Or a flexible body with a certain bending degree is sleeved outside the middle part of the probe body. The flexible body can have a certain width, is convenient to bend and is easy to be hung and recorded on the tooth body.
