Description

Plug structure for microcirculation monitoring and continuous microcirculation monitoring device

Technical Field

The utility model belongs to the design field of microcirculation monitoring especially relates to a mouth stopper structure that supplies microcirculation monitoring to use and use continuous microcirculation monitoring devices of this structure.

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.

Sublingual microcirculation has been gradually emphasized in clinical application because of its advantages such as convenience at bedside and non-invasiveness. 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 continuous diagnosis of pathological changes and quantification of biological diagnosis and regeneration of biological diagnosis and surrounding health: adaptive [ 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.

CN 103445764B, entitled "monitoring device and method for microcirculation imaging", adopts the concept that the transmission depth of polarized light in human tissue can be adjusted, and the field of view and resolution of the device can be adjusted in real time, so as to realize more detailed observation of specific area of microcirculation imaging.

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 without using polarized light.

Above-mentioned patent document has all made the improvement to microcirculation imaging effect, but exists to microcirculation monitoring handheld device because of anterior segment detection part is perpendicular with the tongue bottom, exerts too much pressure influence detection effect and because of anterior segment detection part is shorter and whole detecting instrument is heavier to the tongue bottom when surveying, can't realize the problem of continuous incessant long-term monitoring.

Detailed Description

The following describes in detail a plug structure for monitoring microcirculation and a continuous microcirculation monitoring device using the same according to the present invention with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended 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 bottom of the tongue, and if the operator does not master 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 continuously monitor the same position for a long time, and the physiological shaking of the operator can hurt the patient. 3. The current probe is close to and vertical to the tongue bottom (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 bottom and is easy to extrude mucosa and subcutaneous blood vessels; the probe is far away from the tongue bottom, so that the quality of collected video is influenced; 5. the observation fields of the time-sharing detection 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, etc., affect the accuracy of the monitoring results. 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 plug structure for monitoring microcirculation and a continuous microcirculation monitoring device using the same, which can realize orthotopic, continuous, real-time monitoring of sublingual blood vessel images, and avoid unnecessary damage to patients; meanwhile, the sockets of the medical endoscope and the tracheal cannula are reserved at the oral cavity fixing support respectively, so that the microcirculation monitoring and the operations of the medical endoscope examination, the tracheal cannula and the like can be carried out simultaneously, and the oral cavity fixing support has extremely high application potential in the aspects of visceral examination, operation and the like.

As shown in fig. 2. The continuous microcirculation monitoring device comprises: the device comprises a parallel structure detecting head 1, an oral cavity fixing support 2, an imaging receiving channel and an imaging capturing device. Wherein, the oral cavity fixed support 2 is an oral plug structure for monitoring microcirculation.

When the microcirculation detection is carried out, the parallel structure detecting head 1 horizontally extends into an oral plug structure (an oral cavity fixing support 2) and is in contact with the surface of a tissue including the tongue bottom, an illuminating light beam is projected onto the surface of the tissue including the tongue bottom, an imaging receiving channel collects reflected light scattered and absorbed in the tissue, the collected light changes the light path of the collected light to enable the light path to be parallel to the body of the parallel structure detecting head 1, and an imaging capturing device focuses the light beam to be transmitted.

Specifically, referring to fig. 3, the parallel structure probe 1 includes a housing 101, a light source 102, a reflective mirror 103, a wedge-shaped structural member 104, and a limiting member 105. The housing 101 is cylindrical, the light source 102 is provided on the front end side wall of the housing 101, and when monitoring the tongue base microcirculation, the light source 102 irradiates the tongue base, and the wavelength of the incident light provided by the light source 102 is determined by the absorption spectra of hemoglobin and deoxyhemoglobin in the microcirculation. In the absorption spectra of hemoglobin and deoxyhemoglobin, 420nm, 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.

And 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 1, and the oblique angle is set to change the optical path of the collected light so that the collected light is transmitted out in parallel with the body of the parallel structure detecting head 1. And the imaging capture device (not shown in the figure) 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 processed into microcirculation image information later. The mirror 103 may be fixed to the bottom of the body of the parallel structure probe 1 by a bracket, or may be fixed to the body of the parallel structure probe 1 by a nut or the like. The angle of inclination of the mirror 103 can also be made fine-tunable for convenient reception of effective light information. In this example, in view of the more compact structure of the parallel structure probe, both ends of the mirror 103 may be fixed to the front end bottom and side portions of the body of the parallel structure probe 1, respectively. The imaging receiving channel can also be provided with a plurality of optical elements, and mainly carries out secondary processing on the received light.

When tongue bottom microcirculation monitoring is carried out, after the light source 102 irradiates the tongue bottom, a light beam containing tongue bottom microcirculation information is formed on the surface of the tongue bottom, the light beam changes the direction of a light path after passing through the reflector 103, and the light beam is transmitted out in parallel to the parallel structure detection head 1.

A plurality of wedge-shaped structures 104 are disposed on the outer side wall of the end of the casing 101, and as can be seen from fig. 3, 4 wedge-shaped structures 104 are disposed on the outer side wall of the end of the casing 101 and are uniformly distributed on the side wall to form a ring shape.

A limiting member 105 is further disposed on an outer side wall of the distal end of the housing 101, and the limiting member 105 is located behind the wedge-shaped structural member 104 and is used for limiting the length of the parallel structure probe 1 extending into the oral cavity and preventing the parallel structure probe 1 from moving in a direction perpendicular to the oral cavity fixing bracket 2. The limiting member 105 may be a ring sleeved at the end of the parallel structure probe 1, or may be a structural member of other shapes, as long as the specific limiting function is achieved, the length of the parallel structure probe 1 extending into the oral cavity is limited, and the function of preventing the parallel structure probe 1 from moving in the direction perpendicular to the oral cavity fixing support 2 is also achieved.

When the sublingual microcirculation monitoring is performed, as shown in fig. 4. Because the parallel structure detecting head 1 is parallel to the tongue bottom instead of vertical, the tight fit is achieved, and excessive pressure cannot be applied to the tongue bottom. The parallel structure probe 1 effectively avoids the impact and the oppression of the cylindrical probe to the tongue bottom in the current design.

In order to further control the pressure on the observation part of the tongue bottom, the pressure sensor is arranged at the detection front end of the parallel structure detection head 1, so that a user can adjust the detection distance between the parallel structure detection head 1 and the microcirculation of the tongue bottom according to the feedback of the pressure sensor, and the problems that mucosa and subcutaneous blood vessels are extruded due to the fact that the parallel structure detection head is close to the tongue bottom or the quality of collected video is affected due to the fact that the detector is far away from the tongue bottom are avoided.

Referring to fig. 5, the oral cavity fixing bracket 2 is arc-shaped, a microcirculation probe socket 201 is formed on the middle end surface of the oral cavity fixing bracket 2, and the microcirculation probe socket 201 is a circular hole, the diameter of the circular hole is matched with the diameter of the tail end of the parallel structure probe 1, so that the tail end of the parallel structure probe 1 is inserted into the microcirculation probe socket 201. The inner wall of the microcirculation probe socket 201 is provided with a plurality of clamping grooves 2011, and the positions and the number of the clamping grooves 2011 correspond to the positions and the number of the wedge-shaped structural members 104 at the tail end of the parallel structure probe 1. After the parallel structure probe 1 is inserted into the microcirculation probe socket 201, the wedge-shaped structural member 104 is clamped into the clamping groove 2011, so that the parallel structure probe 1 is fixedly connected with the oral cavity fixing support 2, and the parallel structure probe 1 is prevented from rotating and horizontally moving. And after the wedge-shaped structural member 104 is clamped into the clamping groove 2011, the limiting member 105 at the tail end of the parallel structure detecting head 1 clamps the opening of the micro-circulation probe socket 201, so that the length of the parallel structure detecting head 1 extending into the oral cavity is limited, and the parallel structure detecting head 1 is also used for preventing the parallel structure detecting head 1 from moving in the direction perpendicular to the oral cavity fixing support 2.

An endoscope socket 202 is further arranged on the middle end face of the oral cavity fixing bracket 2, as can be seen from fig. 5, the endoscope socket 202 is cylindrical, an extension section 203 is arranged on the endoscope socket 202 along the direction of the center of the oral cavity fixing bracket 2, and the extension section 203 is a cylindrical ring. The side surface (arc surface) of the extension section 203 is provided with a tracheal insertion opening 204 into which a tracheal cannula can be inserted, so that the patient can breathe smoothly during monitoring. The lower end surface (lower plane) of the extension section 203 is provided with a semicircular opening 205, which is convenient for the tongue of the patient to be placed.

The oral cavity fixing support 2 can be manufactured by 3D integrated printing, and the material can be multi-material resin polymer. The continuous microcirculation monitoring devices that this embodiment provided adopts oral cavity fixed bolster not only to guarantee the continuation to sublingual apposition blood vessel, real-time accurate monitoring, has solved in addition fundamentally and has caused the formation of image unstability that the operator physiological rocked and bring because of handheld instrument, and sublingual because of the problem such as probe oppression bleeds, has greatly improved the security and the practicality of patient monitoring time, has also reduced operator's the work degree of difficulty. And can be used with an endoscope to realize real-time monitoring of sublingual microcirculation during visceral examination and operation. And because the parallel structure detecting head is adopted, the detecting head is parallel to the tongue bottom during the microcirculation detection, and is not in a vertical relation in the traditional detecting head, thereby not only achieving the tight fit, but also not applying excessive pressure to the tongue bottom. The design of the parallel structure probe head effectively avoids the impact and the oppression of the probe head to the tongue bottom in the current design.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, the changes are still within the scope of the present invention if they fall within the scope of the claims and their equivalents.
