Description

[0002] With the continuous development of transdermal drug delivery technology, laser-assisted drug delivery devices, with their unique advantage of promoting drug penetration non-invasively, have been increasingly widely used in rehabilitation therapy, chronic disease management, and other fields. The core principle of this type of device is to irradiate a drug packet attached to the surface of the human skin with a laser of a specific wavelength. The photothermal, photochemical, and mechanical effects generated by the laser synergistically change the barrier structure of the skin's stratum corneum, while activating the motility of the drug molecules in the packet, thereby significantly accelerating the rate of transdermal drug absorption and greatly improving the efficiency and speed of drug efficacy.

The side wall of the sliding housing 6 opposite to the metal detection housing 7 is open, and the open side of the metal detection housing 7 extends into the sliding housing 6. In the figure, the sliding shell 6 is located on the upper and lower sides of the instrument body 1 and is detachably connected to the instrument body 1. The patch electrode 8 is arranged on the side wall of the metal detection shell 7 away from the sliding shell 6. The adjustment spring 9 is located in the sliding shell 6, and its two ends are respectively connected to the inner wall of the sliding shell 6 and the inner wall of the metal detection shell 7.

After the customized medicine bag is applied, the blood sugar lowering function can also be achieved. It is convenient, fast and simple to operate.

[0020] Before treatment, the positioning mechanism can be clipped onto the instrument body 1, wherein the sliding shell 6 can be detachably installed on the top and bottom surfaces of the instrument body 1, and on one side of the sliding shell 6 is a metal detection shell 7, which is connected to the sliding shell 6 by an adjusting spring 9. Under the action of the adjusting spring 9, the outer wall of the metal detection shell 7 can abut against the human skin, so that the patch electrode 8 can contact the human body surface and collect human electrical signals. The sliding shell 6 and the metal detection shell 7 are arranged up and down, so the main control unit 4 can roughly determine the position of the instrument body 1 according to the difference in human electrical signals collected from the upper and lower parts and the commonly used medicine application position of the human body, thereby adjusting the laser parameters emitted by the laser emitting plate 3, including light wavelength, intensity and pulse mode, etc., which can maximize the drug penetration efficiency and avoid skin damage.

[0021] After determining the position of the instrument body 1, the patch electrode 8 can be removed from the human body. When the laser emitting board 3 emits a laser, the reflective photoelectric sensors 11 arranged above and below the metal detection shell 7 can detect whether the laser is emitted. After confirming that the laser is emitted, the main control unit 4 can control the electromagnet 10 to be energized. After the electromagnet 10 is energized, it generates magnetic force to magnetically attract the metal detection shell 7 and remove the patch electrode 8 from the human body.

The available light wavelengths are 480 / 630 / 650nm.

[0026] Preferably, the top and bottom surfaces of the instrument body 1 are both provided with T-shaped slide grooves 16, and the T-shaped slide grooves 16 extend to one side of the instrument body 1. The bottom surface of the upper sliding shell 6 and the top surface of the lower sliding shell 6 are both provided with T-shaped sliders 17, and the T-shaped sliders 17 extend into the T-shaped slide grooves 16. Positioning grooves 18 are provided on both sides of the T-shaped slide grooves 16, and elastic bump beads 19 are provided on the side walls of the T-shaped sliders 17, and the elastic bump beads 19 are embedded in the positioning grooves 18.

After moving to the specified position, the elastic bumper 19 will pop out into the positioning groove 18 to limit the position of the T-shaped slider 17 and prevent the T-shaped slider 17 from sliding out of the T-shaped slide groove 16.

[0028] Preferably, a socket 20 is provided on the end side wall of the T-shaped slide 16, and a plug 21 is provided at the end of the T-shaped slider 17.

[0029] When the T-shaped slider 17 moves to the corresponding position along the T-shaped slot 16, the plug 21 is plugged into the socket 20, so that the electrical components on the sliding housing 6 and the metal detection housing 7 can be electrically connected to the main control unit 4, so that the main control unit 4 can send control commands.

[0030] Preferably, the positioning mechanism also includes a hollow tube 22 and a moving rod 23. The hollow tube 22 is arranged on the inner wall of the sliding shell 6, and the adjusting spring 9 is located in the hollow tube 22. One end of the moving rod 23 extends into the hollow tube 22 and is connected to the adjusting spring 9, and the other end is connected to the inner wall of the metal detection shell 7.

[0031] The setting of the adjustment spring 9 allows the metal detection shell 7 to adjust its position so that it can be used in different positions of the human body. When the metal detection shell 7 is moved by external force, the moving rod 23 can move along the hollow tube 22, and the moving rod 23 is limited by the hollow tube 22 to ensure that the metal detection shell 7 will not be offset.

[0032] Preferably, the positioning mechanism also includes a rotating motor 24, a rotating rod 25, a conductive gel 26 and an electric-controlled nozzle 27. The rotating rod 25 is located on the outer wall of the metal detection shell 7, and the rotating motor 24 is arranged on the inner wall of the metal detection shell 7, and its output shaft is connected to the outer wall of the rotating rod 25. The conductive gel 26 is arranged in the rotating rod 25, and the electric-controlled nozzle 27 is embedded in the outer wall of the rotating rod 25 and is connected to the rotating rod 25. The main control unit 4 is electrically connected to the rotating motor 24 and the electric-controlled nozzle 27.

[0033] Before the patch electrode 8 is brought into contact with human skin, the main control unit 4 can drive the electronically controlled nozzle 27 to spray the conductive gel 26 in the rotating rod 25 onto a designated part of the human body. At the same time, driven by the rotating motor 24, the rotating rod 25 can rotate, thereby spraying the conductive gel 26 onto the position corresponding to the patch electrode 8. When the patch electrode 8 is attached to the surface of the human body, the conductive gel 26 can more accurately collect the human body's electrical signals.

[0034] Preferably, the side wall of the metal detection shell 7 is provided with a receiving groove 28, the rotating rod 25 is located in the receiving groove 28, the output shaft of the rotating motor 24 extends into the receiving groove 28 and is connected to the outer wall of the rotating rod 25, the positioning mechanism also includes a supporting plate 29 and an electric slide 30, the supporting plate 29 is arranged on the inner side wall of the metal detection shell 7, the electric slide 30 is arranged on the supporting plate 29, the rotating motor 24 is arranged on the mover of the electric slide 30, and the main control unit 4 is electrically connected to the electric slide 30.

[0035] The patch electrodes 8 are arranged at the four corners of the outer wall of the metal detection housing 7. As for the rotating rod 25, it is stored in the receiving groove 28. The outer wall is flush with the receiving groove 28. The receiving groove 28 is located in the middle of the metal detection housing 7. In the initial state, the electromagnet 10 magnetically attracts the metal detection housing 7 so that the edge of the metal detection housing 7 does not exceed the light-transmitting window 5. When the conductive gel 26 needs to be sprayed, the electric slide 30 on the supporting plate 29 can drive the rotating motor 24 to move, thereby pushing the rotating rod 25 out of the receiving groove 28. At this time, the rotating rod 25 is located on the outside of the patch electrode 8. When the rotating motor 24 drives the rotating rod 25 to rotate, it will The outer side of the pole 8 rotates, that is, the patch electrode 8 will not block the rotation of the rotating rod 25. When the rotating rod 25 rotates, it can ensure that the conductive gel 26 is sprayed onto the part of the human body corresponding to the patch electrode 8. After the spraying is completed, the rotating rod 25 will return to the receiving groove 28. By cutting off or reducing the current supplied to the electromagnet 10, the metal detection shell 7 can slowly move outward under the action of the adjusting spring 9, and finally the patch electrode 8 can be attached to the human skin. Since the rotating rod 25 is located in the receiving groove 28, it will not hinder the patch electrode 8 from contacting the human body surface, ensuring that the patch electrode 8 can collect accurate human electrical signals.
