Description
Technical Field
The invention belongs to the field of design of microcirculation monitoring, and particularly relates to a microcirculation detection device and system based on a parallel structure detector.
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 and correct clinical parameters that reflect hypovolemia (e.g., tachycardia, oliguria, hyperlactacidosis, or hypo-venous oxygen saturation) will have a positive impact on the patient's condition.
Sublingual microcirculation is gradually emphasized in clinical application due to its advantages of convenience at bedside, non-invasiveness, and the like. 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 the microcirculation of exposed tissues and organs of the human body. The second generation of 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 personal digital field (SDF) imaging used in a clinical model for connecting biological monitoring and quantification of biological monitoring and regeneration of biological monitoring and surrounding health in the same clinical practice: a pilot study [ J ] Arch organic biol.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.

US 2013/0237860 a1, entitled "system and method for monitoring microcirculation overall", discloses an improved imaging of microcirculation by illuminating the tip of a light guide with external direct light to achieve reflection avoidance, i.e. the incident and reflected light do not travel along the same path.
CN 205322304U, entitled "device for obtaining clear microcirculation image", adopts tiny light source projection devices uniformly distributed around the imaging light-passing area, the light emission direction of the tiny light source projection devices forms a projection angle with the direction perpendicular to the object to be detected, and obtains a clear image without being affected by reflected light on the basis of no need of using polarized light.

Detailed Description
The invention provides a parallel structure probe microcirculation device which is further explained in detail by combining the attached drawings and the specific embodiment. Advantages and features of the present invention will become apparent from the following description and from the claims.
The current microcirculation monitoring is only clinical scientific research equipment, but cannot become clinical routine detection equipment. Mainly because the following technical defects are not solved: 1. during monitoring, the probe contacts the tongue, and if the operator does not control the force properly, mucous membranes and subcutaneous blood vessels are easily squeezed, and even the blood vessels are broken; 2. the hand-held microcirculation monitor is heavy in whole, an operator cannot perform continuous monitoring at the same position for a long time, and the patient can be injured by physiological shaking of the operator. 3. The current probe sticks to the tongue closer and perpendicular (as shown in figure 1), and is easy to extrude mucosa and subcutaneous blood vessels; 4. the requirement on operators is high. The probe is close to the tongue, so that mucosa and subcutaneous blood vessels are easily extruded; the probe is far from the tongue, which affects the quality of collected video; 5. the observation fields detected in time-sharing are difficult to be consistent, so that the microcirculation at the same part cannot be continuously monitored and analyzed; 6. the movement of the patient and the operator, secretions (saliva, blood, etc.) in the oral cavity, and the like affect the accuracy of the monitoring result. The defects all seriously affect the imaging quality and finally affect the clinical application and popularization of the microcirculation monitoring instrument.
In order to solve the above problems, the present embodiment provides a microcirculation detection device based on a parallel structure detector, which can realize the monitoring of the same position, continuous and real-time sublingual microcirculation, and avoid unnecessary damage to the patient. In addition, the invention also provides an application example of the microcirculation detection device based on the parallel structure detection body, the oral cavity fixing bracket for fixing is arranged, and the sockets of the medical endoscope and the trachea cannula are reserved at the oral cavity fixing bracket respectively, so that the microcirculation monitoring and the operations of the medical endoscope examination, the trachea cannula and the like can be carried out simultaneously, and the microcirculation detection device has extremely high application potential in the aspects of the visceral examination, the operation and the like of the endoscope.
Examples
Referring to fig. 3 and 4, a microcirculation device for parallel structure probe includes a parallel structure probe head 1, where the parallel structure probe head 1 further includes:
a light source 102 disposed on a side wall of the front end of the parallel structure probe body, the light source providing an illumination beam projected onto a tissue surface including under the tongue;
the imaging receiving channel comprises a reflector 103, the reflector 103 is arranged below the light source 102 and is obliquely arranged in the body of the parallel structure detecting head, and the oblique angle is set to change the light path of the collected light to enable the collected light to be parallel to the body of the detecting head and be transmitted out;
the imaging receiving channel comprises a reflector, the reflector is arranged below the light source and is obliquely arranged in the body of the parallel structure detecting head, and the oblique angle is set to change the light path of the collected light to enable the collected light to be parallel to the body of the detecting head and be transmitted out;
the imaging capture device is used for receiving the light transmitted by the imaging receiving channel and focusing the light into a light beam for transmission so as to be post-processed into microcirculation image information;
when the microcirculation detection is carried out, the parallel structure detection head horizontally extends into the detection head and is in contact with the surface of the tissue including the tongue, the illuminating light beam is projected onto the surface of the tissue including the tongue, the imaging receiving channel collects the light scattered in the tissue and returned to the surface of the tissue, and the collected light changes the light path to be parallel to the detection head body of the imaging capturing device and is focused into the light beam for transmission.
The structure of the present invention will be specifically described below.
The light source 102 is not only a single light source, but also a plurality of light source modules, in this case, the light source can be disposed on the side wall of the front end of the parallel structure probe body. It should be noted that the probe body with a parallel structure mainly defines the front end and the rear end artificially. In use, the end part of the parallel structure probe body contacting with the sublingual space is defined as a front end, and the end part convenient for an operator to hold is defined as a rear end. That is, the light source 102 is disposed at the end of the end that contacts the tongue, and is spaced slightly from the tongue contact, primarily to facilitate the projection of the illumination beam provided by the light source onto the tissue surface, including under the tongue.
One common practice is to form a plurality of holes in the housing of the parallel structure probe body, and install the light source modules in the holes respectively, and set the light source modules that can provide the illuminating beams to be at an angle with the horizontal. Several processing schemes are possible with this example. For example, each light source of the light source assembly is transversely or longitudinally arranged on the side wall of the front end of the parallel structure detecting head body, and the system can control the light sources at different positions to work according to the sublingual difference of people of different ages or sexes, so that the universality of the parallel structure detecting head is improved. For another example, the angle between the light source module and the horizontal direction is adjustable, and during the micro-cycle detection, the operator can adjust the angle so as to adjust the illumination angle of the illumination beam. 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 102 mentioned in this example is a relatively large concept, and includes not only the light source 102 in a narrow sense but also the light source 102 in a broad sense. The light source 102 in the broad sense includes 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 to have a better incident light effect. 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 detection principle of the tongue base microcirculation is briefly described as follows: in imaging microcirculation with orthogonally polarized light, when polarized light is incident under the tongue, a portion of the polarized light is reflected directly by the sublingual surface, and another portion is transmitted through the tongue into the sublingual tissue. In any one scattering, the polarization state of the incident light may change. Where light that is directly reflected or only slightly transmitted into the sublingual surface is only scattered one or a few times before being re-reflected, most of the polarized light will retain its original polarization; light penetrating deeply into sublingual tissue becomes unpolarized light after multiple scattering, and the depolarized unpolarized light returns to the sublingual surface after multiple scattering in human body tissue.
Polarized light is projected into a second medium with refractive index n2 at an incident angle theta 1 in a first medium with refractive index n1, and the refraction angle of the polarized light in the second medium is theta 2.
Since the light penetration depth is related to the incident angle of light, the microcirculation images at different depths under the tongue can be obtained by adjusting the incident angle of the incident polarized light.
According to the fresnel reflection formula, the transmittance (transmission) τ of a light ray propagating in two isotropic media satisfies the following relationship:
τ＝2n1*cosθ1/(n2*cosθ1+n1*cosθ2) (1)
in this embodiment, the first medium is an incident medium, such as air, and the second medium is sublingual tissue, so in formula (1), n1 is the refractive index of the incident medium, n2 is the refractive index of the sublingual tissue, the incident angle θ 1 is the angle at which the polarized light is transmitted from the air to the sublingual skin surface, and the refraction angle θ 2 is the refraction angle at which the polarized light is transmitted into the sublingual tissue.
The transmittance of the polarized light in the second medium is changed along with the change of the incident angle theta, so that light rays scattered back by human tissues with different depth levels can be acquired through subsequent imaging components, and microcirculation images with different depths in the human tissues are acquired after processing.
After the light source irradiates the sublingual tissue, scattered light containing sublingual microcirculation information is formed under the tongue.
