Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a photosensitizer coating and packaging device. Background Art

[0002] The invention and use of antibiotics have made outstanding contributions to the treatment of wound infections. Laboratories and pharmaceutical companies have also been committed to the research and development of new antibiotics. However, with the increase in the use of antibiotics, more and more bacteria have become resistant to antibiotics. In daily life, bacterial infections of the skin or tissues occur from time to time, and the proportion of infections caused by resistant bacteria increases year by year. Traditional antibiotic therapy can no longer quickly and effectively treat wound infections. Photodynamic chemical antimicrobial therapy (PACT for short) has gradually gained popularity due to its rapid and efficient antibacterial characteristics.

[0003] Photodynamic therapy was first used in the treatment of tumors and achieved significant therapeutic effects. As the situation of clinical treatment of drug-resistant bacterial infections becomes increasingly severe, the principle of this therapy is applied to the treatment of bacterial infections and is called PACT. The three basic elements of PACT are: photosensitizer, light, and oxygen. Most photosensitizers are colored complexes, and some have even been used as dyes for dyeing clothes. Photosensitizers can absorb light energy and produce electron transfer reactions, converting light energy into active chemical energy. In the presence of oxygen, active chemical energy will be transferred to oxygen to produce reactive oxygen. Reactive oxygen is a highly oxidizing and unstable state of oxygen that can destroy microbial cell membranes or directly destroy their subcellular structures inside microorganisms.

[0004] When treating a patient, the doctor will first use a cotton swab or other tool to evenly apply the photosensitizer on the patient's affected area. After applying the photosensitizer, local sealing treatment is required to ensure that the photosensitizer can fully penetrate into the lesion site. After sealing for several hours, the doctor will remove the sealing of the affected area and use lighting equipment to continuously illuminate the affected area.

[0005] During the application process, due to the high viscosity of the photosensitizer, the doctor needs more time and effort to ensure that it is evenly distributed on the wound surface. When the doctor applies the photosensitizer to the patient's affected area, the photosensitizer applied first is exposed to natural light in the air. When the photosensitizer is exposed to light, it absorbs light energy and converts it into chemical energy, thereby triggering a series of photochemical reactions. These reactions are likely to change the structure and properties of the photosensitizer, thereby reducing its antibacterial effect. For this reason, we propose a photosensitizer application and packaging device. Summary of the invention

[0006] The object of the present invention is to provide a photosensitizer smearing and sealing device to solve the problem proposed in the above-mentioned background technology that performing these steps step by step not only increases the workload of doctors and the waiting time of patients, but also if the interval between opening the package and operating the lighting device to illuminate the affected area is too long, it will cause the patient to be exposed to natural light or other light sources before illumination, which is likely to affect the treatment effect.

[0041] When in use, the doctor moves the closing box 2 so that the curtain 3 covers the affected area, thereby keeping the application and coating process in a light-proof environment, and then controls the application range of the application mechanism 4 according to the area of ​​the affected area. When the application range of the application mechanism 4 changes, the application mechanism 4 adds a corresponding dose of photosensitizer to the affected area. After the photosensitizer is evenly applied, the affected area is automatically packaged by the packaging mechanism 5, and the packaging is automatically unsealed after the packaging is completed, thereby reducing the doctor's workload and preventing the photosensitizer from being exposed to natural light and causing chemical reactions when the doctor is applying the photosensitizer, thereby affecting the antibacterial effect.

[0042] The smearing mechanism 4 includes a moving box 40, and moving grooves 41 are opened on both sides of the moving box 40. The moving box 40 is slidably connected to the inner wall of the closed box 2 through the moving grooves 41. The moving box 40 is kept stable by the clamping of the moving grooves 41 and the closed box 2, and the moving box 40 is moved out of the center position of the closed box 2 after the photosensitizer is applied. A connecting hole 42 is opened on the inner wall of the moving box 40, and an adjusting block 43 is slidably connected to the inner wall of the connecting hole 42. The limiting blocks 44 are fixedly connected on both sides of the adjusting block 43. The inner wall of the moving box 40 is opened with a connecting hole 42 connected to the limiting block 44.

[0043] When applying photosensitizer to the affected part, the doctor pushes the mobile box 40 to slide on the inner wall of the closed box 2, the mobile box 40 drives the adjusting block 43 to move, the adjusting block 43 drives the rotating plate 47 to move, so that the smearing member 49 and the adding member 410 move to the center of the patient's affected part, the doctor pushes the adjusting block 43 to slide along the inner wall of the mobile box 40, the adjusting block 43 drives the limiting block 44 to slide along the inner wall of the limiting groove 45, and the limiting block 44 and the rubber block 46 squeeze each other to cause the rubber block 46 to deform, so that the limiting block 44 slides over the rubber block 46, and the adjusting block 43 drives the rotating plate 47 is close to the patient's skin, so that the applicator 49 and the additive 410 are close to the patient's affected area. Since the therapeutic device main body 1 does not generate laser when applying the photosensitizer, the doctor pulls open the curtain 3 to cooperate with observing the affected area and adjusts the applicator 49 according to the affected area. After the applicator 49 is adjusted, the additive 410 controls the amount of photosensitizer dripped on the affected area according to the adjustment range of the applicator 49. After the additive 410 adds the photosensitizer, the rotating plate 47 is driven to rotate by the rotating member 48, and the rotating plate 47 drives the applicator 49 to rotate to cooperate with evenly applying the added photosensitizer to the affected area.

[0045] When the rotating member 48 is working, the doctor rotates the rotating wheel 416 outside the adjusting block 43, the rotating wheel 416 drives the transmission rod 415 to rotate, the transmission rod 415 drives the transmission gear 672 to rotate, the transmission gear 672 drives the toothed belt 413 to rotate, the toothed belt 413 drives the transmission gear 671 to rotate, the transmission gear 671 drives the rotating column 411 to rotate, thereby driving the rotating plate 47 to rotate through the rotating column 411, so that the application member 49 evenly disperses the photosensitizer on the surface of the affected area.

[0046] The smear member 49 includes a plurality of trapezoidal plates 417 slidably connected to the inner wall of the rotating plate 47, the plurality of trapezoidal plates 417 are arranged in a straight line, a scraper 418 is fixedly connected to the end of the trapezoidal plate 417, sliders 419 are fixedly connected to both sides of the trapezoidal plate 417, a slide groove 420 slidably connected to the slider 419 is provided on the inner wall of the rotating plate 47, a spring sheet 421 is fixedly connected to the outer side of one of the sliders 419, the spring sheet 421 is fixedly connected to the inner wall of the slide groove 420, an adjustment hole 422 is provided on the inner wall of the rotating plate 47, the adjustment hole 422 is located on the outer side of the hypotenuse of the trapezoidal plate 417, an adjustment hole 423 is provided on the inner wall of the rotating column 411, and the adjustment hole 423 is connected to the inner wall of the slide groove 420. The adjusting hole 1 422 is connected, and an adjusting hole 3 424 is provided on the inner wall of the adjusting block 43. The adjusting hole 3 424 is connected to the adjusting hole 2 423. Balls 425 are arranged on the inner walls of the adjusting hole 1 422, the adjusting hole 2 423 and the adjusting hole 3 424. A transmission screw 426 is rotatably connected to the inner wall of the adjusting hole 3 424. One end of the transmission screw 426 passes through the inner wall of the adjusting block 43 and is fixedly connected to a rotating handle 438. A push rod 427 is threadedly connected to the outer side of the transmission screw 426. The push rod 427 abuts against the ball 425. The outer side of the push rod 427 is fixedly connected to a limiting block 2 428. A limiting groove 2 429 is provided on the inner wall of the adjusting hole 3 424 and is slidably connected to the limiting block 2 428.

[0047] When adjusting the application range, the doctor turns the rotating handle 438 on the outside of the adjusting block 43, and the rotating handle 438 drives the transmission screw 426 to rotate. The transmission screw 426 is fixed-free end in the adjusting block 43, that is, one end is fixed and the other end is free, which is a common way of screw installation. Therefore, the transmission screw 426 drives the outer push rod 427 to move, and the push rod 427 drives the limit block 428 to slide along the inner wall of the limit groove 429, and when the push rod 427 slides on the inner wall of the adjusting hole 424, the push rod 427 squeezes the ball 425. Since the rotating column 411 is rotatably connected to the inner wall of the adjusting block 43, when the balls 425 squeeze each other, the balls 425 are pressed against each other. 25 rolls on the inner walls of adjusting hole 1 422, adjusting hole 2 423 and adjusting hole 3 424, so that the ball 425 located in the adjusting hole 1 422 squeezes the hypotenuse of the trapezoidal plate 417, and as the ball 425 moves, the ball 425 pushes the trapezoidal plate 417 to slide outward, and the trapezoidal plate 417 drives the scraper 418 to move so as to get close to the patient. The movement of the trapezoidal plate 417 drives the slider 419 to slide along the inner wall of the slide groove 420 and squeeze the spring sheet 1 421. The multiple scrapers 418 are extended and combined together to cooperate in evenly spreading the photosensitizer on the affected area. The doctor observes whether the shape formed by the scrapers 418 is sufficient to cover the entire affected area with the photosensitizer by pulling open the curtain 3.

[0048] The adding component 410 includes a feeding box 430 installed on the inner wall of the rotating plate 47, and a photosensitizer is placed in the feeding box 430. A piston plate 431 is slidably connected to the inner wall of the feeding box 430. An electric telescopic rod 439 is fixedly connected to one side of the piston plate 431, and the electric telescopic rod 439 is installed on the inner wall of the feeding box 430. A transmission pipe 432 is connected to the outer side of the feeding box 430. A feeding groove 433 is provided on the inner wall of the rotating plate 47.

A closing plate 435 is slidably connected to the inner wall of the discharge port 434. A connecting port 436 is provided on the surface of the closing plate 435. The slider 419 is slidably connected to the closing plate 435, and the end of the closing plate 435 away from the slider 419 is fixedly connected to a spring sheet 2 437.

[0049] When adding photosensitizer to the affected area, as the doctor turns the handle 438 to make the pressing tablets approach the affected area one by one, the trapezoidal plate 417 drives the slider 419 to move, and the slider 419 slides on the inner wall of the slide groove 420 while pushing the closing plate 435 to move, so that the connecting port 436 on the surface of the closing plate 435 is connected with the discharge port 434, and the closing plate 435 moves to squeeze the spring sheet 437, so that as many scrapers 418 extend, as many connecting ports 436 of the closing plate 435 move to the position of the discharge port 434, and a control button for controlling the activation of the electric telescopic rod 439 is installed on the outer side of the adjustment block 43. When the shape formed by the scrapers 418 is sufficient to cover the entire affected area with the photosensitizer, the doctor activates the electric telescopic rod 439 through the control button, so that the electric telescopic rod 439 pushes the piston plate 431 in the adding box 4 30 The inner wall moves, the piston plate 431 moves, and the photosensitizer in the feeding box 430 is sent to the feeding trough 433 through the transmission tube 432. The photosensitizer in the feeding trough 433 is discharged through the discharge port 434 under the action of pressure and gravity. Since the diameters of the plurality of discharge ports 434 increase successively, the photosensitizer doses discharged from the discharge ports 434 with different diameters are different, that is, along the arrangement direction of the scraper blades 418, less photosensitizer is added on the inner side, while more photosensitizer is added on the outer side. The doctor pulls open the curtain 3 to observe the dose of photosensitizer added to the affected area. The more the scraper blades 418 extend, the longer the doctor presses the control button, so that the electric telescopic rod 439 pushes the piston plate 431 to move a longer distance on the inner wall of the feeding box 430, so as to cooperate with the scraper blades 418 to evenly apply the added photosensitizer to the affected area when the rotating plate 47 rotates.

[0051] After the photosensitizer is evenly applied to the affected area, the cylinder 55 drives the mounting seat 53 to move along the inner wall of the sealing box 2. When the mounting seat 53 moves, it drives the rotating shaft 52 to move. At this time, the driving motor 54 does not work. The rotating shaft 52 moves to pull the packaging belt 51. The packaging belt 51 drives the winding wheel to rotate, so that the packaging belt 51 is unfolded above the affected area. The clamping piece 56 works to make the packaging belt 51 close to the surface of the affected area, thereby completing the packaging treatment of the affected area.

[0052] The clamping member 56 includes a clamping ring 57 located on the outside of the sealing tape 51, and a cylinder 2 58 is fixedly connected to the outside of the clamping ring 57. The cylinder 2 58 is installed on the inner wall of the sealing box 2. When the clamping member 56 is working, the cylinder 2 58 extends to drive the clamping ring 57 to move, so that the clamping ring 57 is close to the sealing tape 51 and presses the sealing tape 51 against the patient's skin surface to cooperate with the sealing treatment of the affected area applied with the photosensitizer, thereby reducing the workload of doctors.

[0053] Embodiment 2

[0054] In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the therapeutic device body 1 is connected to the outside of the closed box 2, and the inner wall of the closed box 2 is provided with a light adjustment mechanism 6 for adjusting the illumination range of the therapeutic device body 1 according to the application range of the application mechanism 4. The light adjustment mechanism 6 includes a rotating ring 60 rotatably connected to the inner wall of the closed box 2, and a driving member 61 is provided on the outer side of the rotating ring 60 to drive the rotating ring 60 to rotate. The driving member 61 is connected to the slider 419, and a plurality of baffles 62 are provided under the rotating ring 60. The baffles 62 are located outside the illumination port of the therapeutic device body 1, and the end of the baffle 62 is fixedly connected to the limit rod 63. The inner wall of the closed box 2 is provided with a limit groove three 64 slidably connected to the limit rod 63, and the inner wall of the rotating ring 60 is provided with a connecting groove 65 slidably connected to the limit rod 63.

[0055] When in use, the therapeutic device body 1 moves to the outside of the patient's wound when the closing box 2 moves. After the doctor adjusts the extension amount of the scraper 418, the driving member 61 controls the rotation amplitude of the rotating ring 60 according to the extension amount of the scraper 418. When the rotating ring 60 rotates, the connecting groove 65 rotates synchronously, and the inner wall of the connecting groove 65 squeezes the limiting rod 63. The limiting rod 63 slides along the inner wall of the limiting groove three 64 while driving the baffle 62 to move. Multiple baffles 62 move synchronously to cooperate with the adjustment of the illumination range of the therapeutic device body 1 to prevent the laser from causing damage to the patient's normal skin.

[0056] The driving member 61 includes a transmission gear ring three 66 fixedly connected to the outside of the rotating ring 60, and a transmission gear 67 is meshed on the outside of the transmission gear ring three 66. One end of the transmission gear 67 is fixedly connected to the inner wall of the closed box 2, and the other end of the transmission gear 67 is fixedly connected to a rotating motor 68, and the rotating motor 68 is installed on the inner wall of the closed box 2. A magnet sheet 69 is fixedly connected to the bottom of the slider 419. An iron block 610 is slidably connected to the inner wall of the rotating plate 47. A return spring 611 is fixedly connected to the outside of the iron block 610. The return spring 611 is fixedly connected to the inner wall of the rotating plate 47. A travel switch 612 is provided on the outside of the iron block 610. The travel switch 612 is located on the inner side of the return spring 611, and the travel switch 612 is installed on the inner wall of the rotating plate 47. The travel switch 612 is connected to the rotating motor 68, and the travel switch 612 is installed on the inner wall of the rotating plate 47.

[0057] When the ball 425 pushes the trapezoidal plate 417 to move, the trapezoidal plate 417 drives the slider 419 to slide along the inner wall of the slide groove 420, and the slider 419 drives the magnet sheet 69 to move, so that the magnet sheet 69 is separated from the iron block 610. After the iron block 610 is separated from the magnet sheet 69, the reset spring 611 in the stretched state pulls the iron block 610 to reset. After the iron block 610 is reset, it squeezes the travel switch 612, so that as the ball 425 squeezes different trapezoidal plates 417 to move, different travel switches 612 are triggered, and the travel switch 612 sends a trigger signal to the rotating motor 68. The rotating motor 68 drives the transmission gear 67 to rotate, and the transmission gear 67 drives the transmission gear ring three 66 to rotate. Therefore, according to the number of times the travel switch 612 is triggered, the rotating motor 68 controls the transmission gear 67 to rotate different circles, so that the transmission gear ring three 66 rotates different amplitudes to cooperate with the adjustment of the illumination range of the therapeutic device body 1.
