Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a blood perfusion reconstruction monitoring device. The present invention also relates to a blood perfusion reconstruction monitoring method using the blood perfusion reconstruction monitoring device. Background Art

[0002] After skin transplantation, plastic surgery, finger amputation, and limb amputation surgeries, it is necessary to monitor the transplanted skin, amputated finger, or limb to determine its survival status. Taking skin transplantation as an example, whether the transplanted skin can successfully survive mainly depends on whether an effective blood circulation is established between the transplanted skin and the autologous skin. Therefore, it is crucial to monitor the status of the patient's transplanted skin.

[0003] In the related art, initially, the status of the transplanted skin is usually monitored by observing the color and temperature of the transplanted skin to evaluate the blood flow patency, that is, by measuring the temperature at regular intervals and observing the color of the transplanted skin by visual inspection. Later, a contrast agent is injected and then the blood flow is observed through professional equipment. Monitoring the color of the transplanted skin by visual inspection, for subtle color changes, can only rely on the experience of medical staff for subjective judgment, resulting in doubts about the monitoring effect; while the contrast agent improves the accuracy of the monitoring effect, but the equipment is expensive and the operation is cumbersome and cannot be monitored in a timely manner, resulting in inconvenience in accurately monitoring the blood perfusion status. Summary of the Invention

[0004] In view of this, the present invention aims to provide a blood perfusion reconstruction monitoring device to facilitate accurate monitoring of the blood perfusion status.

[0005] To achieve the above object, the technical solution of the present invention is realized as follows:

[0006] A blood perfusion reconstruction monitoring device, characterized by comprising:

[0007] A light source and a photoelectric sensor disposed on a housing; and both the light source and the photoelectric sensor are electrically connected to a main control board within the housing;

[0008] The light source includes a first light-emitting diode; the photoelectric sensor includes a first receiver and a second receiver;

[0009] Both the first receiver and the second receiver form a first monitoring channel for monitoring blood oxygen data with the first light-emitting diode;

[0010] The connection line between the first receiver and the second receiver forms a triangle with the projection of the first monitoring channel on the bottom surface of the housing.

[0011] Furthermore, the projections of the two first monitoring channels on the bottom surface of the housing form a first included angle; the first included angle is 40° - 50°

[0012] Further, the first light-emitting diode and the first receiver, as well as the first receiver and the second receiver, are all distributed on the housing at a first spacing; the first spacing is 3 mm - 5 mm.

[0013] Further, the light source further includes a second light-emitting diode, and the second light-emitting diode and the first light-emitting diode emit light alternately; and both the first receiver and the second receiver form a second monitoring channel for monitoring blood oxygen data with the second light-emitting diode; a part of the second monitoring channel is cross-distributed with the first monitoring channel.

[0014] Further, one or more of a WIFI module, a mobile network module, and a Bluetooth module are provided on the main control board to form a signal connection with the acquisition terminal.

[0015] Further, the blood perfusion reconstruction monitoring device further includes a power supply assembly; the power supply assembly includes a storage battery and a charging interface, the storage battery is fixedly connected in the housing to supply power to the main control board, the light source, and the photoelectric sensor, the charging interface is connected to an external power supply to charge the storage battery, and / or, the power supply assembly includes a super capacitor, and the super capacitor supplies power to the main control board, the light source, and the photoelectric sensor.

[0016] Further, a solar panel is fixedly connected to the housing, and the solar panel is electrically connected to the power supply assembly; and / or, a microwave receiver is provided on the housing, and the microwave receiver is electrically connected to the power supply assembly.

[0017] Further, a temperature sensor is provided on the housing, the temperature sensor is electrically connected to the main control board, and the temperature sensor is located between the light source and the photoelectric sensor.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] For the blood perfusion reconstruction monitoring device of the present invention, the near-infrared light generated by the light source penetrates the human tissue and is reflected diffusely and then the signal is received by the photoelectric sensor. Since there are obvious differences in the absorption spectra of oxyhemoglobin and reduced hemoglobin in human tissue, the signal received by the photoelectric sensor is convenient for analysis to monitor the blood perfusion reconstruction situation in the monitoring area; compared with the existing method that relies on the subjective judgment of medical staff, the accuracy of the monitoring result is increased, and compared with the existing method of injecting contrast agents, it has the effect of facilitating non-invasive monitoring of the monitoring area. And by setting the connection line between the first receiver and the second receiver to form a triangle with the projection of the first monitoring channel on the bottom surface of the housing, the length required for arranging the light source and the photoelectric sensor is reduced, thereby facilitating the reduction of the bottom area of the housing, so as to fix the blood perfusion reconstruction monitoring device on the area to be monitored.

[0020] Secondly, by setting and adjusting the first angle and the first spacing, the length and width of the space occupied by the light source and the photoelectric sensor integrated on the housing are minimized, which is conducive to the application of the revascularization monitoring device in a smaller monitoring area and helps to improve applicability.

[0021] In addition, by setting the second light-emitting tube to emit light alternately with the first light-emitting tube, and cooperating with the first receiver and the second receiver to form a second monitoring channel, the monitoring points of the monitoring area are increased, and the number of photoelectric sensors is reduced, which helps to miniaturize the revascularization monitoring device. After the skin is transplanted, the suture area needs to be wrapped with gauze to reduce the risk of infection. For this reason, the miniaturization of the revascularization monitoring device, especially the miniaturization of the contact surface with the monitoring area, helps to improve the applicability of the revascularization monitoring device; such a setting increases the accuracy of the monitoring data on the basis of miniaturization.

[0022] At the same time, by setting up a temperature sensor, the temperature of the monitoring area can be monitored, so that the blood circulation in the area can be judged by the temperature change of the monitoring area. And by setting the temperature sensor between the light source and the photoelectric sensor, the volume of the shell can be reduced, which helps to achieve miniaturization and lightness.

[0023] Another object of the present invention is to provide a blood circulation remodeling monitoring method, wherein at least two housings with light sources and photoelectric sensors are attached to the patient's desired monitoring area; each light source is controlled in turn to monitor the blood oxygen of multiple monitoring channels formed in the monitoring area;

[0024] Compare the blood oxygen saturation values ​​in the same monitoring area and give warnings or abnormal signals for values ​​with large deviations.

[0025] Furthermore, the shell is adhered to the monitoring area by means of a low-viscosity pressure-sensitive adhesive.

[0026] The revascularization monitoring method described in the present invention is to set up at least two revascularization monitoring devices to cover the patient's skin transplant area or the surrounding area of ​​the skin transplant area to screen out monitoring data abnormalities caused by poor blood circulation caused by the patient's limb activities or excessive compression near the skin transplant location.

[0049] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0050] Embodiment 1

[0051] This embodiment relates to a blood perfusion monitoring device for accurately monitoring the blood perfusion state.

[0052] In terms of the overall structure, as Figures 1 to 6 shown, the blood perfusion monitoring device includes a light source 2 and a photoelectric sensor 3 provided on a housing 1; and both the light source 2 and the photoelectric sensor 3 are electrically connected to a main control board 101 inside the housing 1; the light source 2 includes a first light-emitting diode 201; the photoelectric sensor 3 includes a first receiver 301 and a second receiver 302; both the first receiver 301 and the second receiver 302 form a first monitoring channel 4 for monitoring blood oxygen data with the first light-emitting diode 201; the connection line between the first receiver 301 and the second receiver 302 and the projection of the first monitoring channel 4 on the bottom surface of the housing 1 form a triangle.

[0053] With the above settings, the near-infrared light generated by the light source 2 penetrates the human tissue, and after diffuse reflection, the signal is received by the photoelectric sensor 3. Since there are obvious differences in the absorption spectra of oxyhemoglobin and reduced hemoglobin in human tissue, the signal received by the photoelectric sensor 3 is convenient for analyzing the blood perfusion reconstruction situation in the monitoring area; compared with the existing method that relies on the subjective judgment of medical staff, the accuracy of the monitoring result is increased, and compared with the existing method of injecting contrast agents, it has the effect of facilitating non-invasive monitoring of the monitoring area. By setting the connection line between the first receiver 301 and the second receiver 302 to form a triangle with the projection of the first monitoring channel 4 on the bottom surface of the housing 1, the length required for arranging the light source 2 and the photoelectric sensor 3 is reduced, thereby facilitating the reduction of the bottom area of the housing 1, so as to fix the blood perfusion reconstruction monitoring device on the area to be monitored.

[0054] It should be noted that the light source 2 mainly generates near-infrared light with a wavelength in the range of 700nm - 1000nm, which has good penetrability to human tissue. The near-infrared light is absorbed by oxyhemoglobin and reduced hemoglobin in the tissue after diffuse reflection. Since there are obvious differences in the absorption spectra of oxyhemoglobin and reduced hemoglobin, the maximum absorption spectrum of oxyhemoglobin is in the range of 850nm - 1000nm, and the maximum absorption spectrum of reduced hemoglobin is 700nm - 760nm. Then, based on the modified Lambert-Beer law, the tissue blood oxygen and cerebral blood oxygen saturation values in the monitoring area are obtained by near-infrared spectroscopy.

[0055] Based on the above overall introduction, there are two first monitoring channels 4 in this embodiment, that is, a first monitoring channel 4 is formed by the first light-emitting diode 201 and the first receiver 301, and another first monitoring channel 4 is formed by the first light-emitting diode 201 and the second receiver 302. The data of the two first monitoring channels 4 are collected and compared to avoid the influence of different skin colors on the monitoring results.

[0056] It should also be noted that the main control board 101 is used to regularly send commands to the light source 2 to collect signals, and can receive the blood oxygen data collected by the photoelectric sensor 3. After processing the blood oxygen data, the blood oxygen saturation data corresponding to the area of the light source 2 is obtained. And it can transfer the data to the acquisition terminal, and the acquisition terminal can be one or more of a mobile phone, a tablet computer, a smart watch, a desktop computer or a notebook.

[0057] To facilitate the blood perfusion monitoring of the skin at different positions, such as Figures 4 to 6As shown in the figure, the projections of the two first monitoring channels 4 on the bottom surface of the housing 1 form a first included angle α; the first included angle α is 40° - 50°. The first included angle α can be, for example, 40°, 45° or 50 degrees, etc. On this basis, the first light-emitting diode 201 and the first receiver 301, as well as the first receiver 301 and the second receiver 302 are all distributed on the housing 1 at a first distance a; the first distance a is 3 mm - 5 mm. The first distance a can be, for example, 3.5 mm, 4 mm or 5 mm. Let any value of the first distance a in the range of 3 mm - 5 mm be x, then the straight-line distance between the first light-emitting diode 201 and the second light-emitting diode 202 is Then the monitoring depth of the first monitoring channel 4 between the first light-emitting diode 201 and the second light-emitting diode 202 is Since the depths of blood vessels in different regions from the epidermis are different, for example, the blood vessel depths at the fingertips, anterolateral femoral flap, and inferior epigastric artery flap are significantly different, setting different sizes of the first distance a can enable this blood circulation reconstruction monitoring device to monitor the blood circulation of the skin at different depths.

[0058] With the above settings, when the first included angle α is fixed, different first distances a can be used to monitor the blood oxygen of blood vessels at different depths. And when the first distance a is fixed, it is preferably set that the first included angle α is 45°, so that the connection line between the first receiver 301 and the second receiver 302 and the projection of the first monitoring channel 4 on the bottom surface of the housing 1 form an isosceles right triangle, minimizing the length and width of the space occupied by the light source 2 and the photoelectric sensor 3 integrated on the housing 1. This is beneficial for this blood circulation reconstruction monitoring device to be applied in a monitoring area with a small area, and helps to improve the applicability.

[0059] To improve the monitoring accuracy of the blood circulation situation in the monitoring area, as Figures 1 to 6 shown, the light source 2 further includes a second light-emitting diode 202, and the second light-emitting diode 202 and the first light-emitting diode 201 emit light alternately; and both the first receiver 301 and the second receiver 302 form a second monitoring channel 5 for monitoring blood oxygen data with the second light-emitting diode 202; some of the second monitoring channels 5 are cross-distributed with the first monitoring channels 4.

[0060] By setting the second light-emitting diode 202 and the first light-emitting diode 201 to emit light alternately, and cooperating with the first receiver 301 and the second receiver 302 to form the second monitoring channel 5, the number of monitoring points in the monitoring area is increased, and the number of photoelectric sensors 3 is reduced, which helps to miniaturize this blood circulation reconstruction monitoring device. When skin transplantation is performed, the suture area needs to be wrapped with gauze to reduce the risk of infection. Therefore, the miniaturization of the blood circulation reconstruction monitoring device, especially the miniaturization of the contact surface with the monitoring area, helps to improve the applicability of this blood circulation reconstruction monitoring device; such settings increase the accuracy of monitoring data on the basis of miniaturization.

[0061] And since part of the second monitoring channels 5 are cross - distributed with the first monitoring channels 4, a linear monitoring path is formed into a mesh - shaped monitoring path after overlapping, improving the monitoring area of the monitoring region.

[0062] As an alternative implementation, the second light - emitting diodes 202 and the first light - emitting diodes 201, as well as the second light - emitting diodes 202 and the second receivers 302, are both distributed on the housing 1 at a second pitch b. The second pitch b is 3 mm - 5 mm. The second pitch b can be, for example, 3.5 mm, 4 mm, or 5 mm. Preferably, the second pitch b is set to be the same as the first pitch a. In this way, when performing blood oxygen monitoring at a certain depth, the area of the housing 1 occupied by the light source 2 and the photoelectric receivers is minimized, and the monitoring surface of the monitoring region is the widest.

[0063] On the above basis, to further improve the accuracy of the monitoring results, as Figure 1 shown, a temperature sensor 8 is provided on the housing 1. The temperature sensor 8 is electrically connected to the main control board 101, and the temperature sensor 8 is located between the light source 2 and the photoelectric sensor 3.

[0064] By setting the temperature sensor 8, the temperature monitoring of the monitoring region is realized, which is convenient for judging the blood circulation condition of the region through the temperature change of the monitoring region. And by setting the temperature sensor 8 between the light source 2 and the photoelectric sensor 3, the volume of the housing 1 is reduced, which helps to achieve miniaturization and light weight.

[0065] It should be noted that the temperature of the transplanted skin is an important indicator reflecting its blood circulation state. Under normal circumstances, the temperature of the transplanted skin should be similar to that of the surrounding healthy skin. If the temperature of the transplanted skin abnormally rises or falls, it may indicate poor blood circulation or other problems. For example, when there is blood circulation disorder in the transplanted skin, such as arterial embolism or venous return obstruction, its temperature may change. When there is arterial embolism, the temperature of the transplanted skin may suddenly drop; while when venous return is obstructed, due to blood stasis, the temperature may gradually rise.

[0066] To facilitate the main control board 101 to transfer data to the acquisition terminal, as Figure 3 shown, the main control board 101 is provided with a WIFI module 1011, a mobile network module 1012, and a Bluetooth module 1013 to form a signal connection with the acquisition terminal. Through the above settings, it is convenient for medical staff to flexibly view the blood circulation conditions of the transplanted skins of different patients, which helps to reduce the workload of medical staff and improve the efficiency of observing the blood circulation state.

[0067] To facilitate the monitoring of patients, as Figure 1 and Figure 3As shown, the revascularization monitoring device further includes a power supply component 6, and the power supply component 6 includes: a storage battery 601 fixedly connected inside the housing 1 to supply power to the main control board 101, the light source 2, and the photoelectric sensor 3; a charging interface 602 connected to an external power supply to charge the storage battery 601. With such a setting, there is no need to plug in a power cord to the housing 1 in real time, thus facilitating the movement of the patient.

[0068] As another implementation manner of the power supply component 6, the power supply component 6 includes a super capacitor 9, and the super capacitor 9 supplies power to the main control board 101, the light source 2, and the photoelectric sensor 3. By setting the power supply component 6 as the super capacitor 9, the power supply component 6 has both the fast charge and discharge capabilities of a capacitor and the power storage characteristics of a battery.

[0069] Based on the above introduction of the power supply component 6, during implementation, specifically, any one or both of the different implementation forms of the power supply component 6 can be selected.

[0070] As a preferred implementation manner for charging the power supply component 6, as Figure 1 shown, a solar panel 7 is fixedly connected to the housing 1, and the solar panel 7 is electrically connected to the storage battery 601 to supply power to the storage battery 601. By providing the solar panel 7 on the housing 1, it is realized that under sunlight or fluorescent lamp irradiation, the storage battery 601 is charged by the solar panel 7 to meet the daily power consumption requirements and reduce the number of charging times.

[0071] As an alternative implementation manner of the solar panel 7, specifically, during implementation, the solar panel 7 can be fixedly connected to the top surface of the housing 1, and the fixed connection method can be bonding or clamping, or the solar panel 7 is fixed to the circumferential wall of the housing 1 and then used as the top plate of the housing 1 to form the housing 1.

[0072] As another implementation manner for charging the power supply component 6, a microwave receiver 10 is provided on the housing 1, and the microwave receiver 10 is electrically connected to the power supply component 6. During specific implementation, a microwave transmitter is correspondingly arranged in the ward, corridor, or hospital campus. The microwave receiver 10 receives the microwave generated by the microwave transmitter and converts it into electrical energy to realize power supply to the power supply component 6. Charging the power supply component 6 in the form of microwave has the advantages of no pollution, no noise, etc.

[0073] Based on the above introduction of the forms for charging the power supply component 6, during specific implementation, any one or both of the solar panel 7 and the microwave receiver 10 can be provided on the housing 1.

[0074] In the blood perfusion reconstruction monitoring device according to the embodiment of the present application, the main control board 101 controls the first light-emitting tube 201 and the second light-emitting tube 202 to emit light alternately, thereby forming a first monitoring channel 4 and a second monitoring channel 5 in the monitoring area; at the same time, the temperature sensor 8 monitors the temperature of the monitoring area, and the measured data is transmitted by the main control board 101 to the acquisition terminal, so as to enable medical staff to understand the blood perfusion condition of the monitoring area.

[0075] The near-infrared light generated by the light source 2 penetrates the human tissue and the signal is received by the photoelectric sensor 3 after diffuse reflection. Since there are obvious differences in the absorption spectra of oxyhemoglobin and reduced hemoglobin in human tissue, the signal received by the photoelectric sensor 3 is convenient for analysis of the blood perfusion reconstruction condition in the monitoring area; compared with the existing method that relies on the subjective judgment of medical staff, the accuracy of the monitoring result is increased, and compared with the existing method of injecting contrast agents, it has the effect of facilitating non-invasive monitoring of the monitoring area. By setting the connection line between the first receiver 301 and the second receiver 302 to form a triangle with the projection of the first monitoring channel 4 on the bottom surface of the housing 1, the length required for arranging the light source 2 and the photoelectric sensor 3 is reduced, thereby facilitating the reduction of the bottom area of the housing 1, so as to fix the blood perfusion reconstruction monitoring device on the area to be monitored.

[0076] Embodiment 2

[0077] This embodiment relates to a blood perfusion reconstruction monitoring method. First, at least two housings 1 with a light source 2 and a photoelectric sensor 3 are attached to the monitoring part required by the patient; then, each light source 2 is controlled in sequence to perform blood oxygen detection on the multiple detection channels formed in the monitoring area; finally, the blood oxygen saturation values in the same monitoring area are compared, and for the values with large deviations, a warning or abnormal signal is given.

[0078] It is set that at least two such blood perfusion reconstruction monitoring devices are attached to the skin graft area or the area around the skin graft area of the patient, so as to screen out the abnormal monitoring data caused by poor blood circulation due to the patient's limb movement or excessive compression near the skin graft position.

[0079] As an implementation manner of fixing the housing 1 on the grafted skin, specifically, during implementation, the housing 1 is pasted on the monitoring area through a low-viscosity pressure-sensitive adhesive. By using a low-viscosity pressure-sensitive adhesive, sufficient viscosity can be provided without damaging the surface of the adhered object, realizing the functions of temporary fixation and protection.

[0080] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
