[0016] Hereinafter, the device for percutaneous drug infiltration, blood flow promotion, and cell activation of the present invention will be described with reference to the drawings. EXAMPLES

[0017] FIG. 1 is a block diagram of a transdermal drug solution infiltration, blood flow promotion, and cell activation device 100 according to the present invention, which is composed of a main body 1 and a probe 2. The main body 1 is powered by an AC adapter 3 that converts AC 100V power into DC. The main body 1 is box-shaped and includes an operation unit 4, a control unit 5, a display unit 6, and an adapter unit 7. The operation unit 4 and the display unit 6 are provided on the surface of the main body 1. The probe 2 is cylindrical, has a cap 10 that transmits near-infrared light and red visible light at one end, a start-stop switch 11 at the other end, a built-in vibration motor 8, and a built-in light source 12 for near-infrared light and red visible light. For example, a wavelength of 855 nm can be used for the near-infrared light, and a wavelength of 630 nm can be used for the red visible light. The main body 1 and the probe 2 are connected by an interface cord 9. Although not shown, an L-shaped holding plate is attached to one side of the main body 1, into which the head 2b of the probe 2 is fitted so as to be freely removed with the head 2b facing upward.

[0018] The control unit 5 (see FIG. 1) includes a processor and a memory, is program-controlled, and includes a wireless communication function. It includes a Wi-Fi wireless LAN, and can connect to a server or a PC (personal computer) via the nearest access point and the Internet. It also includes a SIM card (a card with an ID number that identifies a mobile phone subscriber), and can connect to a server or a PC via a mobile phone company. For example, a server can be installed at a customer center to read the operation information of the transdermal drug solution infiltration, blood flow promotion, and cell activation device 100, and calculate and bill the rental fee. The operation information sent to the server includes (a) the user's name, (b) the date and time of use, (b) the operating strength, (c) the operating time, and (d) the operating status of the device (normal operation, failure, location of failure). Using the wireless communication function, it is also possible to operate the operation unit from a mobile phone.

[0019] A billing terminal (not shown) is connected to main unit 1 (see Figure 1). The usage fee is displayed on the billing terminal, and when the user holds their mobile phone over it, the billing terminal accesses the payment management company via the Internet to confirm whether the payment is OK. If the payment is OK and completed, the billing terminal sends a driving operation permission signal to main unit 1. When main unit 1 receives the driving operation permission signal, it turns on the power, which is in standby mode. If the payment is not OK, for example if payment is completed in cash, the user must manually operate operation unit 4 of main unit 1.

[0020] FIG. 2 is a diagram showing details of the operation unit 4 of the main body 1. The power is turned on by flipping the power-on switch 13 to one side. The power is turned off by flipping it to the other side. The mode selection button 4a of the operation unit 4 selects setting menus m1 to m3 (see FIG. 5). The mode changes each time it is pressed, and if pressed multiple times, it cycles through m1 ⇒ m2 ⇒ m3 ⇒ m1. m1 is a menu for setting the number of rotations of the vibration motor 8, m2 is a menu for setting the period of intermittent vibration of the vibration motor, and m3 is a menu for setting the irradiation intensity of near-infrared light and red visible light. Select m1 to m3 and select the intensity from the displayed menu.

[0021] The start-stop switch 4b shown in Fig. 2 is a switch for starting operation. The start-stop switch 11 of the probe 2 is also the same switch, improving operability. When the start-stop switch 4b is pressed, near-infrared light and red visible light are emitted from the cap 10 of the probe 2, and the probe 2 vibrates. When it is pressed again, the emission of near-infrared light and red visible light stops, and the vibration also stops.

[0022] The intensity up button 4c and the intensity down button 4d (see Fig. 2) are used to set the desired value by increasing or decreasing the numerical value within the range displayed when one of the setting menus m1 to m4 is displayed on the display unit 6 using the mode selection button 4a. The timer up button 4e and the timer down button 4f are used to set the operating time, which can be set within the range of 5 to 40 minutes.

[0023] Fig. 3 is a diagram showing the configuration of the adapter unit 7 in Fig. 2. The adapter unit 7 has an interface circuit with the probe 2. The adapter unit 7 has a vibration motor drive circuit 16, a near-infrared light drive circuit 17, a red visible light drive circuit 18, and a receiving circuit 19 for the start-stop switch 11. Since the near-infrared light source 12a and the red visible light source 12b are built into the probe 2, outputs from the near-infrared light drive circuit 17 and the red visible light drive circuit 18 are sent to the probe 2. These drive circuits and receiving circuits are connected to the control unit 5 in a bus format, and control data is exchanged between them.

[0024] There are several types of probes 2. Although not shown in FIG. 3, a model signal of the probe 2 can be sent to the main unit 1. The control unit 5 can determine the type of probe by looking at the model signal of the connector 15. For example, the number of LEDs varies depending on the probe model, so it is possible to pass a current appropriate for this. When there are a large number of LEDs, the diameter of the cap is large. The rating of the vibration motor 8 can also be notified to the main unit 1.

[0025] Fig. 4 is a diagram showing a flow chart of the control unit 5. After power is turned on in S1, the time of the operation timer and the strength of the stimulation are set in advance in S2. S3 is a determination as to whether the start-stop switch 11 of the probe 2 in Fig. 1 or the start-stop switch 4b of the operation unit in Fig. 2 has been pressed. When the switch is pressed and operation is started, operation is performed at the intensity set in advance. Operation continues until the time of the operation timer in S5 is reached or the start-stop switch 11 of the probe 2 or the start-stop switch 4b of the operation unit 4 is pressed in S6.

[0026] FIG. 5 is a table showing details of the setting menu (m1 to m3). When m1 to m3 are selected, the display unit 6 displays a value A in the settable range and a value B to be set. The intensity up button 4c and the intensity down button 4d are used to confirm the value B to be set. The rotation speed of the vibration motor 8 of m1 can be set in the range of 1.5k to 12krpm, for example. If one cycle of the intermittence of the vibration motor 8 of m2 is expressed as (rotation, brake), it can be set with one touch to one of (rotation, brake) = (0.4 seconds, 0.4 seconds), (rotation, brake) = (5 seconds, 3 seconds), or (rotation, brake) = (10 seconds, 5 seconds). The intensity of the near-infrared light and red visible light of m3 can be set in the range of irradiation intensity from small to large. It cannot be set to an arbitrary value, and multiple vibration frequencies are displayed to allow selection. In this way, the rotation speed of the vibration motor 8, the intermittence cycle, and the irradiation intensity of the light source can be set individually, so that the intensity of the stimulation that suits each person can be set.

[0027] FIG. 6 is a side view of the probe 2. The probe 2 is composed of a grip portion 2a to be held in the hand and a head portion 2b. A cap 10 is provided on the head portion 2b. The cap 10 is made of polycarbonate resin. Polycarbonate is durable and has high light transmittance. Both the front and back surfaces are mirror-finished, so the light transmittance is 86%, and if only the front surface is mirror-finished, the light transmittance is about 40%. If the mirror finish is not applied after processing, the light transmittance is 10% or less. A cap with high light transmittance can increase the total light flux irradiated to the skin and does not trap heat in the cap. The surface of the cap 10 is coated with a fluororesin. The fluororesin coating can improve abrasion resistance and solvent resistance and maintain transparency. A plurality of ventilation slits 10a are provided along the outer periphery of the head portion 2b of the probe 2, which communicate with the internal space. This allows air to circulate with the outside. Heat accumulated inside the cap 10 due to heat generated by the near-infrared light source 12a can be released to the outside. This has the effect of releasing a certain amount of heat to the outside without providing a fan. Metal folds 2c are provided all around the grip portion 2a and head portion 2b of the probe 2, so heat can be dissipated to the outside from these folds as well. The probe 2 may be made of resin. Small ventilation holes may be provided in the cap 10.

[0028] FIG. 7 is a diagram showing a near-infrared light source 12a and a near-infrared light drive circuit 17. A light-emitting diode (LED) can be used for the light source 12a. This circuit is the same for both the near-infrared light drive circuit 17 and the red visible light drive circuit 18. The LED can send a square wave of a PWM signal (Pulse Width Modulation) to achieve a predetermined irradiation intensity, and the irradiation intensity can be increased or decreased. In FIG. 7, if the ON signal width is widened and the OFF signal width is narrowed, the irradiation intensity increases.

[0029] FIG. 8 is an operation table of the vibration motor 8 and the switches (SW1-4). FIG. 9 is a diagram explaining the rotation and brake of the vibration motor 9. The vibration motor 8 is a DC motor with an eccentric weight attached to the rotating shaft, and the rotation speed can be, for example, 1.5k-12krpm. In this case, one rotation is one stimulation (pressure), and the frequency of the stimulation is 25-200Hz. This is calculated as 25 times / second from 1500rpm÷60 seconds, and 200 times / second from 12000rpm÷60 seconds. Four switches SW1-SW4 are provided around the vibration motor 8 and are switched. As shown in the table of FIG. 8, for example, forward rotation occurs when SW1 and SW4 are turned on and electricity is applied. Reverse rotation occurs when SW3 and SW2 are turned on and electricity is applied. When SW1 and SW3 are turned off and SW2 and SW4 are turned on, the brake is applied. This can act as a brake because a back electromotive force is generated by the rotation of the rotor, which becomes electric energy and current flows. The vibration motor 8 rotates for a short time and brakes for a short time, and this is repeated. In this case, one period of the intermittent operation can be set as (rotation, brake) = (0.4 seconds, 0.4 seconds), (rotation, brake) = (5 seconds, 3 seconds), or (rotation, brake) = (10 seconds, 5 seconds). See Figure 5. This allows the vibration to become a compound vibration due to the repeated rotation and braking of the vibration motor in addition to the fast stimulation by the eccentric weight, changing the stimulation and providing a relaxing stimulation that is not monotonous. Note that even if SW1 and SW3 are on and SW2 and SW4 are off, there is no power supply to the vibration motor 8, so it can act as a brake. [Industrial Applicability]

[0030] This device irradiates the skin with near-infrared light and applies vibrations, making it suitable for activating skin cells and infiltrating medicinal fluids. It is also effective as a device for promoting blood circulation and reducing inflammation and analgesia. [Explanation of symbols]
