Description

Lattice discharging device

Technical Field

The invention relates to the field of medical care. In particular to a dot matrix discharge device.

Background

The existing physiotherapy equipment usually works with limited electrodes, namely 2 electrodes, or 4 electrodes, or 8 electrodes, and utilizes direct current or alternating current to stimulate skin, meridian and muscle with voltage and current which can be borne by a human body, and massages and stimulates certain parts of the human body. They cannot simulate the force effect of continuous slow movement in manual massage, such as the process of slowly pushing from the lower back to the upper, and the continuous pressure stimulation cannot be simulated by common electrodes. Their approach is deficient because only limited electrodes can be used for large span stimulation and the control pattern varies little. For example, in a meridian massage apparatus, there are at most 4 electrodes, each two electrodes are a pair, and only two parts can be energized at the same time, so that the user feels that the relevant areas of the 2 pairs of electrodes are stimulated at the same time, and the user cannot simulate manual massage manipulation, i.e., slowly push the massage from one side to the other side. Because the number of the electrodes is small, the electrodes cannot be multiplexed, the current and voltage regulation can be carried out between 2 pairs of electrodes, the controllable waveform is also carried out between 2 points, the sensing is only carried out between the two points, the electrodes cannot move freely, and therefore the sensing cannot move. The effects of circular, wandering, spiral, jumping and the like cannot be achieved. Has the defects of single form, single perception and the like. For example CN 209490378U, which uses only one positive electrode and one negative electrode. For example CN 209237166U uses only a limited number of electrode pairs. For example, CN 105744984 a uses a plurality of electrodes, but its purpose is to realize bidirectional current flow at fixed positions without forming a lattice. For example, CN 107875508A uses bidirectional electrodes to realize bidirectional massage, for example, CN 209679299U uses multiple electrodes and is bidirectional electrode, but also carries out long-span electrotherapy on several parts of human body. None of them appears in the form of a lattice, so there are no features characteristic of lattices: the effects of massage, circular, wandering, spiral, jumping and the like are realized.

Detailed Description

In order to more fully understand the technical content of the present invention, the technical solution of the present invention will be further described and illustrated with reference to the following specific embodiments, but not limited thereto.

Defining the drive voltages 2-12v high can also be denoted as 1. Defining the ground voltage as low may also be represented as 0.

Fig. 1 shows a conventional half bridge, which is widely used, and upper and lower arms are N MOS transistors, and two N MOS transistors are driven by using a bootstrap voltage boosting circuit and an IC. An electrode is led out from between the two N MOS circuits as shown in a circuit, and the electrode can be metal or conductive rubber. When h1=1 and h2=1, the upper arm is open and the lower arm is closed, current flows from VCC100 to the upper arm and reaches the electrode, the electrode is represented as a positive electrode, when h1=0 and h2=0, the upper arm is closed and the lower arm is open, current flows from the electrode to the lower arm and reaches GND, the electrode is represented as a negative electrode, when h1=1 and h2=0 or h1=0 and h2=1, the upper arm and the lower arm are both closed (the chip is different, the values of h1 and h2 are different), current cannot flow, and the electrode is represented as a floating electrode. Thus, the electrode can be a positive electrode or a negative electrode or be suspended. Controlling h1 and h2 can put the electrodes in arbitrary states.

As shown in the functional diagram of fig. 4, and with reference to fig. 5, 6, and 7, the circuit of the dot matrix discharge device is completely implemented in this example. The power supply is a lithium battery, the output is about 4v, boost is the most basic boost circuit, as shown in fig. 7, boost is connected with the lithium battery, pwm1 is connected with a CPU, pwm1 drives an Nmos tube by driving a mos-dedicated driving ic to enable VCC100 to generate high voltage, resistors R11 and R10 form a voltage dividing resistor, the voltage of VCC100 is measured, pwm1 is reduced or stopped when the voltage exceeds a set value, the voltage of VCC100 is reduced, the voltage of VCC100 is between 50 and 100v, and the maximum continuous discharge current can be adjusted to be not more than 1 milliampere. The 8 data buses are named Dxx, and are connected with a group of 4 electrodes after passing through a latch. The level of the Qx pin is the same as that of the Dx pin when the LE pin of the latch is at a high level, the level of the latch Qx is the same as that of the Dx pin when the LE pin is at a low level, the LE is taken as an address line, one address line is arranged in each group, and 12 groups of 12 address lines are arranged in total. When a single chip microcomputer wants to control a certain group of electrodes, the single chip microcomputer only needs to send the values of the 4 electrodes of the group to Dxx, then an address line LE of the group is enabled to be high, hx is changed into the state of Dxx, namely Dxx is high, hx is high, Dxx is low, hx is low, the output value of a latch controls the on-off of the upper arm and the lower arm of a mos tube through a bootstrap booster circuit and an IC, the electrodes are enabled to be in a positive pole or negative pole or suspended state, after the operation of one group of electrodes is finished, the next group is controlled through the process. Multiple electrodes can be operated simultaneously to be positive electrodes, multiple electrodes can be discharged to be negative electrodes, or multiple 1 positive electrode and multiple negative electrodes can be discharged. The relevant electrodes are thus controlled, and the desired circuit is realized.

In the default state, all electrodes are suspended. Unless the CPU commands that a certain electrode be either positive or negative. Others not illustrated are floating.

A plurality of electrodes are regularly arranged. The invention adopts two arrangement modes:

FIG. 2 is a plane lattice arrangement diagram, in which a bottom plate is an insulating rubber plate, 48 electrodes in 8 rows and 6 columns are adopted, the electrodes protrude out of the bottom plate or are flush with the bottom plate, a flexible FPC circuit board is used as the circuit board, the whole body can be bent, and legs or the back can be attached to the circuit board to be used as a physiotherapy instrument, in FIG. 2, 1-8 are electrodes, 10 are insulating rubber plates, and 9 is a circuit board; fig. 3 is a diagram of a cylindrical lattice arrangement, the bottom plate is insulated, 48 electrodes in 8 rows and 6 columns are adopted, the electrodes protrude out of the bottom plate or are flush with the bottom plate, the circuit board adopts 6 PCB strips to form a 6-face body, the insulating bottom plate and the conductive rubber electrodes are coated outside the circuit board, the whole body is cylindrical, the top part of the circular body can be attached to a vagina to be used as a vagina massaging or stimulating instrument, in fig. 3, 1 is a rubber electrode, 2 is a circuit board, and 3 is an insulating rubber plate to be used as a shell.

This example defines 1 column as 8 electrodes, divided into two groups, each column from top to bottom, the top four as one group, the bottom four as one group, for a total of 6 columns, for a total of 12 groups.

The working process is as follows: CPU data bus sends out order, order certain electrode to show the positive pole, certain electrode shows the negative pole, other electrodes are unsettled, address line selects a latch first, make data send out to the half-bridge driver chip of corresponding electrode, half-bridge driver chip makes mos pipe open or close according to the data, and then make the electrode connect VCC or ground connection or unsettled, the discharge time is at tens of microseconds levels, guarantee that the organism is not hurt, data bus sends out order, order all electrodes unsettled, then address line is 0, release this latch. If the electrodes of two different groups are discharged, the data bus sends out data, the address line selects a latch first, then the address line releases the latch, the data bus sends out data, and the address line selects the next latch, so that the electrodes of 2 different groups can be discharged. The time interval between the last discharge and the next discharge can be maintained in a time range which cannot be distinguished by a human body, namely, tens of microseconds. The last and next discharge time intervals may also be maintained on the order of hundreds of microseconds within a human-discernable time frame.

According to the present example and fig. 2, the effect of jumping is achieved: the first column electrode 1 is a positive electrode, the electrode 5 is a negative electrode, the data bus sends out 11101010 data according to the arrangement of D11-D81, the address line selects the first latch, the data is output 11101010 after passing through the latch, then h1=1, h2=1, h3=1, h4=0, h5=1, h6=0, h7=1, h8=0, the electrode 1 is positive electrode, the

electrodes

2, 3, 4 are floating, the first latch is released, then the data bus sends out 00101010, the address line selects the second latch, the electrode 5 is negative electrode, the

electrodes

6, 7, 8 are floating, the release latch, VCC discharges tens microseconds through the

electrodes

1, 5, the data bus sends out 00000000, the address line selects the two latches, then sends out 10101010, the release latch, then h1=0, h2=0, h6=0, h4=0, h5=0, h = 29 =0, h 460 = 84 = 397370, h2, h3=1, h4=0, h5=1, h6=0, h7=1, h8=0, the electrodes 1-8 are all suspended, and the discharge of the upper left corner is finished. No action, after 200 microseconds, the sixth row electrode 4 is made to be the anode electrode 8 to be the cathode, the bus output is 10101011, the latch selects the 11 th electrode, the electrode 4 is the anode, the latch is released, the bus output is 10101000, the latch selects 12, the electrode 8 is the cathode, the latch is released, VCC discharges for tens of microseconds through the electrodes, the data bus sends out 00000000 and then sends out 10101010, the latch selects 11 and 12, and the sixth row electrode 1-8 is grounded and then suspended. The body can feel that the upper left gets an electric shock first and the lower right gets an electric shock later. Thus, any different electrode discharges can achieve the effect of jumping.

According to the present example and fig. 2, the effect of massage is achieved: the first row electrode 1 is the positive electrode 4 and the negative electrode is closed after discharging, and the second row electrode 1 is the positive electrode 4 and the negative electrode is closed … … after discharging for a few microseconds, and the steps are repeated until the sixth row. After 500 microseconds the first column electrode 2 is discharged as positive electrode 5 and then turned off … … and repeats to the sixth column. After discharging the first column electrode 3 as positive electrode 6 as negative electrode 500 microseconds, … … turn off and repeat to the sixth column. Since the microsecond time is short enough that the human body cannot distinguish the specific discharge part, just like television scanning, as long as the time is short enough that the human body cannot distinguish, the human body can be considered to be simultaneous, and the human body can be distinguished within 500 microseconds, so that the discharge occurs slowly from top to bottom in sense. The manipulations of tuina were simulated.

The flow and the principle of the cylindrical dot matrix for massaging the vagina are the same as those of a plane type. The circuit is entirely concentrated within the cylinder. Is convenient and portable.

The cylindrical lattice realizes a spiral effect: the cylindrical electrode is a plane electrode after being unfolded, the first column of electrodes 1 is anode 2 which discharges for dozens of microseconds, the second column of electrodes 2 discharges for dozens of microseconds for anode 3 which discharges for 500 microseconds, the third column of electrodes 3 discharges for anode 4 which discharges for … … until the sixth column of electrodes 6 discharges for anode 7 which discharges for anode, after 500 microseconds, the first column of electrodes 7 which discharges for anode 8 which discharges for anode, the result realized on the surface of the cylinder is that the discharge surrounds the cylinder for one circle and from top to bottom, and the discharge is carried out successively, and the spiral effect is realized.

Because the CPU can control each electrode to be presented as a positive electrode or a negative electrode or suspended, and because the electrodes are arranged in a lattice form. The controlled discharges occur organoleptically at the same time within an indistinguishable time of the human body. The interval between this discharge and the next discharge is long enough to be discernable by the senses, which are then a shock at a moment in the senses and a shock at a moment in the senses. When the discharge is regular, the manual method can be simulated, and the effects of circular, wandering, spiral, jumping and the like are realized.

The CPU drives the half-bridge through the latch and then drives the mos tube to enable any electrode to be represented as a positive electrode or a negative electrode or be suspended, the characteristic of the dot matrix can realize discharge similar to dynamic scanning of the LED screen, the fact that the LED screen discharges to the place where the LED screen scans is achieved, and when the discharge time and the discharge interval are well matched, the CPU can finally achieve various special effects which cannot be achieved by the existing equipment.

The technical content of the present invention is further illustrated by the examples, so that the reader can easily understand the technical content, but the technical content does not represent that the embodiment of the present invention is limited to the examples, and any technical extension made by the present invention is protected by the present invention. The protection scope of the invention is subject to the claims.
