Description

Optical medical device and using method thereof

Technical Field

The invention relates to the technical field of medical devices, in particular to an optical medical device and a using method thereof.

Background

In recent years, phototherapy has achieved significant clinical effects in treating diseases, and has become one of the main methods for treating diseases, and photodynamic therapy is a method for treating diseases by directly using light or using light and drugs in combination, and is currently applied to clinical medicine. There are two main ways of photodynamic therapy, one is direct light therapy, and the other is light therapy and drug (also called photosensitizer) synergistic therapy. The direct light therapy is to directly irradiate the affected part with one or more kinds of light, and has the effects of sterilizing, disinfecting, promoting cell metabolism, promoting cell regeneration, promoting cell secretion of chemical substances (such as serotonin) and promoting blood circulation. The medical process of the synergistic effect of light and medicine is that the laser irradiation with specific wavelength excites the photosensitizer absorbed by the tissue, and the excited photosensitizer transfers the energy to the surrounding oxygen to generate singlet oxygen with strong activity, and the singlet oxygen and the adjacent biological macromolecules generate oxidation reaction to generate cytotoxicity effect, thereby causing cell damage and even death. At present, the phototherapeutic treatment can treat skin diseases such as herpes zoster, alopecia areata, phlebitis, erysipelas, acne, paronychia, chilblain and the like, surgical diseases such as wound infection, abscess, ulcer and the like, gynecological diseases such as chronic pelvic inflammatory disease, adnexitis, cervical erosion, leukoplakia vulvae and the like, internal diseases such as infantile diarrhea, ischemic heart disease, chronic gastritis and the like, and other diseases such as otorhinolaryngology department, burn department and the like.

In the existing optical medical device, because the irradiation area and the area of the light source are fixed, the irradiation area is often larger than the treatment area during treatment, so that normal skin tissues are forced to receive treatment, which is not favorable for the treatment of patients; in the prior art, some technical schemes adopt an image recognition method to recognize a treatment area, and a light source selectively treats the recognized area to be treated, so that the method can seemingly solve the problem of forced treatment, but in the actual use process, the difference between the treatment area and normal skin tissues on image development is not obvious, and the treatment area and the normal skin tissues can be observed only by careful observation, so that the recognition accuracy of the image recognition method is poor, sometimes even false recognition occurs, and the problem of forced treatment cannot be fundamentally solved.

The light sources used for the optical medical device at present are a strong light source and a weak light source, and the strong light source is mainly 10000mW/cm²The low-light source is mainly 100mW/cm²The light source inside the medical device can be an OLED or an LED, the medical device with the strong light source is not convenient to wear, most of the medical devices can only be used in hospitals, and a patient needs to be kept still for a long time in the illumination time, so that a lot of inconvenience is brought to the patient, and the treatment cost of the patient is increased. In addition, general patients avoid diseases of genital organs and private parts, but in addition, the strong light source damages normal tissues due to too strong power when treating diseases, and in addition, the laser light source and the LED have poor uniformity of light emission, which is not favorable for treatment of affected parts with large areas.

As shown in fig. 4, a basic schematic block diagram of the optical medical apparatus provided in this embodiment is provided, and as can be understood by those skilled in the art, as the optical medical apparatus, the apparatus has a basic input module 35, the input module 35 may include a start button and a signal input panel, the signal input panel may be, for example, a display screen with a touch screen, and a user may input control information such as treatment time, treatment intensity, etc. through the input panel; the control module 30 is a core control device of the apparatus, and controls the OLED light source 10 by receiving signals from the input module or the sensing module.

Wherein, as shown in fig. 1, the sensors 21 of the sensing module 20 are uniformly distributed on the surface of the device, for example, when corresponding to the device structure shown in fig. 3, the sensors 21 are uniformly distributed on the working surface of the photomedical device; as shown in fig. 5, each sensor 21 is attached to a narrow strip of connecting wires 22, and each connecting wire 22 is glued to the surface of the OLED light source 10; the connection line 22 is in signal connection with the control layer 10 from the side across the OLED light source 10; the connection line 22 may be FPC, and is adhered to the OLED light source 10 by a skin-friendly adhesive DOPA-substituted polyethylene glycol polymer, fibrin glue, or alkyl- α -cyanoacrylate glue, or may be directly a skin-friendly conductive pressure-sensitive adhesive, which may realize electrical connection between the sensor 21 and the control layer 60, and may be adhered to the surface of the OLED light source 10. This is just one embodiment of the specific distribution of the sensors, and in other embodiments, for example, as shown in fig. 6, the OLED light source 10 may be composed of a plurality of independent light sources, or may be provided with upper and lower through holes, and the sensors 21 disposed on the control layer may be passed out to the surface of the device from the gaps between the independent light sources or through holes.

Wherein, the sensor 21 can be any one or more of a pressure sensor, a humidity sensor or a pH sensor;

Electron. Mater.2020, 1901311.

A humidity sensor: the humidity sensor is suitable for the condition that the diseases can cause the obvious humidity increase, and various humidity sensors with proper dimensions are adopted, such as the sensors disclosed by Li-Chia Tai and the like, Drug-ports Silicon double luminescence System for Monitoring and Inhibition of round Infection, adv.

pH sensors, suitable for use in conditions where the condition causes a significant change in pH, may be referred to as the sensors disclosed in Chen X, Wo F, Jin Y, et al, drug-port Silicon Dual luminescence System for Monitoring and Inhibition of round Infection [ J ] Acs Nano,2017: acsano.7 b02471.

TABLE 1

When the area to be treated is a pimple-shaped area, the pressure sensors at the respective positions detect the values as shown in table 2 below:

TABLE 2

When the above method 1 is adopted, then the peak value in all status signals is determined to be the status signal value 0.55 detected by the pressure sensor at the array position (6, 4); the first set difference range is, for example, 0.2 to 0.25, and the edge status signal ranges from 0.35 to 0.3, so that the edge position signals can be determined to be (3,2), (4,2), (5,2), (6,2), (7,2), (8,3), (8,4), (8,5), (8,6), (8,7), (7,9), (6,9), (5,9), (4,8), (4,7), (3,7), (2,6), (2,5), (2,4), (3, 3); therefore, the edge position information and the position information in the surrounding area thereof are determined as the treatment position information, and the light emitting area corresponding to the treatment position information is lit, so that the light emitting area to be lit is determined as the shaded area shown in fig. 7a in the present example.

In the embodiment, the severe region and the mild region can be judged according to the magnitude of the pressure difference value, and different irradiation intensities are adopted for treating the severe region and the mild region, so that the targeted and adaptive treatment on different degrees of disease regions is realized; for example, a severe signal region is defined where the status signal value is 0.4 or more, and the corresponding light-emitting region is shown as a dark shaded region in fig. 7b, which has stronger illumination intensity; defining the status signal value below 0.4 is a light signal area, and the corresponding light emitting area is shown as the light shaded area in fig. 7b, and the light intensity is weaker.

When the above method 2 is adopted, for example, the threshold value is set to 0.25, and the light emitting region to be lit is determined to be a shaded region as shown in fig. 7c in this example.
