Description

TECHNICAL FIELD

[0001] The utility model relates to medical or health electron acupuncture instrument field, concretely relates to an electron acupuncture instrument of fine strength adjustment. BACKGROUND

[0002] Acupuncture originated in China and has a long history. After a long development, it gradually formed a unique theoretical system and treatment method. In modern times, with the rapid development of microelectronics, acupuncture and electrical stimulation are combined to form a unique electroacupuncture method. The electroacupuncture instrument can reliably provide stable bioelectric stimulation to patients for a long time, and has the effect of enhancing the curative effect.

[0003] Traditional electronic acupuncture instruments generally use a knob to adjust the stimulation intensity. For example, a type-A linear potentiometer knob is used. This linear potentiometer has two sections of resistance slope, which can be customized. The purpose of using this linear potentiometer is to share the electrode needle and the electrode sheet. The front half of the slope is low, so the intensity grows slowly, which is suitable for electrode needle application. The back half of the slope is high, so the intensity grows quickly, which is suitable for electrode sheet application. However, this application has some risks: first, the maximum intensity of the front half may not meet the requirements of electrode needle application. When the electrode needle is applied to a non-sensitive part, the doctor may mistakenly adjust the intensity to the back half of the slope of the linear potentiometer, causing the patient to be unable to tolerate the excessive stimulation; second, when applied to a very sensitive part such as a finger, the adjustment of the front half of the slope may still cause the patient to be unable to tolerate the stimulation even if the slope is low; third, when applied to the electrode sheet treatment, the patient may also be unable to tolerate the stimulation due to the high slope and poor precision of the knob.

[0004] Some improvements have been made to existing electroacupuncture instruments, such as using a type-B linear potentiometer knob, which only retains the electrode needle part. This design improves the adjustment requirements of the electrode needle part, and the adjustment of the electrode needle is more delicate. However, this is at the expense of the application of the electrode sheet, and it is not possible to accommodate both the electrode needle and the electrode sheet. In addition, the actual adjustment is not truly fine, and it cannot meet the delicate adjustment requirements of sensitive parts. Therefore, to meet the needs of multiple applications in the same hospital, multiple electroacupuncture instruments of different types need to be purchased, which will cause a heavy economic burden and complicated equipment management and switching for the hospital.

[0005] Therefore, how to design a product that can be applied to both electrode needle application and electrode sheet application and can be finely adjusted in various application scenarios has become a research topic for the utility model. UTILITY MODEL CONTENT

[0043] Referring to the accompanying Figs. 1-3 As shown in the drawings, a fine strength adjustment electronic acupuncture instrument includes a power conversion module 1, a display module 2, a control module 3, a fine adjustment module 4, an acupuncture waveform output module 5, and an output circuit composed of a patient application module 6, a treatment head 7 and a human body. The treatment head 7 includes an electric needle and an electrode sheet.

[0044] The control module 3, the acupuncture waveform output module 5, the fine adjustment module 4 and the display module 2 are all electrically connected with the power conversion module 1. The power conversion module 1 converts 220V AC mains into DC power for use by each module.

[0045] The control module 3, the acupuncture waveform output module 5 and the patient application module 6 are electrically connected in sequence. The control module 3 can use a single-chip microcomputer. The single-chip microcomputer can output a level signal to control the acupuncture waveform output module 5 to adjust the frequency and pulse width of the waveform output to the patient application module 6 according to the received external instructions.

[0046] The display module 2 is electrically connected with the control module 3. The control module 3 can send the waveform frequency, the operation time of the acupuncture instrument and other working conditions to the display module 2 for display by the display module 2 for the staff to check.

[0047] The fine adjustment module 4 is connected to the voltage input end of the acupuncture waveform output module 5, and the fine adjustment module 4 comprises a first linear potentiometer W1 and a second linear potentiometer W2.

[0048] In the embodiment, the first linear potentiometer and the second linear potentiometer are both B-type linear adjustment potentiometers, which have better uniformity than A-type potentiometers and are more delicate in the sense. In addition, a potentiometer with a larger rotation angle, such as a device with a rotation angle of 300 degrees or more, can be used to increase the adjustment stroke and make the intensity adjustment more delicate.

[0049] In the embodiment, the first linear potentiometer comprises a first resistor body, a first switch pin and a first sliding pin. The two ends of the first resistor body are 1C end and 1B end, the two ends of the first switch pin are 1D end and 1X end, and the first sliding pin is 1A end. The first sliding pin of the first linear potentiometer is connected to the voltage input end of the acupuncture waveform output module 5, and the first linear potentiometer adjusts the voltage output to the acupuncture waveform output module 5 within the voltage limit range. The other end (1B end) of the first resistor body of the first linear potentiometer is grounded. By moving the first sliding pin of the first linear potentiometer, the voltage output to the acupuncture waveform output module 5 can be finely adjusted.

[0050] In the embodiment, the second linear potentiometer comprises a second resistor body, a second switch pin and a second sliding pin. The two ends of the second resistor body are 2C end and 2B end, the two ends of the second switch pin are 2D end and 2X end, and the second sliding pin is 2A end. One end (2B end) of the second resistor body of the second linear potentiometer is electrically connected to the power conversion module 1, and the other end (2C end) of the second resistor body is grounded. The second sliding pin of the second linear potentiometer is connected to one end (1C end) of the second resistor body of the first linear potentiometer, and the second linear potentiometer adjusts the voltage limit of the output voltage of the first linear potentiometer. The voltage generated by the second sliding pin of the second linear potentiometer is the maximum value (upper limit of pulse output intensity) that the first linear potentiometer can adjust, i.e. the voltage limit, which can be adjusted by moving the second sliding pin of the second linear potentiometer.

[0051] When 1C end is the maximum voltage Vc1, the voltage variation range when 1A end slides is 0~Vc1, and the voltage output to the acupuncture waveform output module 5 is 0~Vc1.

[0052] When 2B end is the maximum voltage Vb2, the voltage variation range (voltage limit range) when 2A end slides is 0~Vb2. Since the 2A end of W2 is connected to the 1C end of W1, the voltage of the 2A end of W2 determines the voltage of the 1C end of W1, i.e. the voltage of the 2A end of W2 determines the upper limit of pulse output intensity.

[0053] In the embodiment, one end (2B end) of the second resistor of the second linear potentiometer is connected in series with a voltage limiting resistor (R6) on the connecting line of the power conversion module 1, and the voltage limiting resistor divides voltage with the second linear potentiometer, so as to limit the maximum voltage limit value regulated by the second linear potentiometer.

[0054] In the embodiment, a filter capacitor (C5) is connected in parallel on the line between the first sliding pin of the first linear potentiometer and the ground end (1B end) of the first resistor, and when the first sliding pin moves along the resistor, the filter capacitor can play a filtering role to stabilize the output voltage of the first sliding pin.

[0055] In the embodiment, one end (1D end) of the first switch pin of the first linear potentiometer is electrically connected with the 51st pin of the single-chip microcomputer, and the other end (1X end) of the first switch pin is grounded. The control module 3 detects the switch state of the fine adjustment module 4, and controls the needle therapy waveform output module 5 to open or close according to the switch state, that is, when the potentiometer of the fine adjustment module 4 is turned on, the control module 3 controls the needle therapy waveform output module 5 to turn on and perform needle therapy.

[0056] In the embodiment, the use mode of the two linear potentiometers can be: first adjust the second linear potentiometer to a suitable position according to the sensitivity of the treatment site, and then adjust the first linear potentiometer to a position where the patient has a body feeling. The position of the first linear potentiometer is generally appropriate at about half the stroke.

[0057] When the treatment head 7 adopts electric acupuncture, if it is used in a high-sensitivity part of electric acupuncture, the voltage limit value can be adjusted to be smaller, and if it is used in a low-sensitivity part of electric acupuncture, the voltage limit value can be adjusted to be slightly larger.

[0058] When the treatment head 7 adopts an electrode sheet, the voltage limit value can be adjusted to the maximum, and the first linear potentiometer will further subdivide the voltage limit value of the second linear potentiometer. By moving the first sliding pin of the first linear potentiometer, the voltage can be subdivided, and the subdivided voltage is delivered to the needle therapy waveform output module 5, and the actual pulse output is generated through the needle therapy waveform output module 5.

[0059] In the embodiment, the needle therapy waveform output module 5 includes a pulse switch circuit and a constant-current pulse amplification circuit. The input end of the pulse switch circuit is connected with the output end of the control module, the output end of the pulse switch circuit is connected with the input end of the constant-current pulse amplification circuit, the input end of the constant-current pulse amplification circuit is electrically connected with the sliding pin of the first linear potentiometer, and the output end of the constant-current pulse amplification circuit is electrically connected with the input end of the patient application module.

[0060] The pulse switch circuit includes a resistor R5, a voltage stabilizing diode ZD1, a resistor R1, and a triode Q1.

[0061] The constant current pulse amplification circuit comprises an operational amplifier U1A, a resistor R4, a current limiting resistor R3, a field effect tube Q15, a resistor R7, a freewheeling diode D1 and a primary coil of a transformer T1.

[0062] The patient application module 6 comprises a secondary coil of the transformer T1 and a voltage limiting resistor R2 connected in parallel with the secondary coil.

[0063] Wherein: one end of R5 is connected with the OUT pin of the single-chip microcomputer, and the other end is connected with the base of Q1; the emitter of Q1 and one end of R1 are connected with the power conversion module; one end of ZD1 is grounded; the other end of ZD1 is connected with the other end of R1 and the base of Q1; the collector of Q1 is connected with the No.4 pin of the operational amplifier U1A; the No.3 pin of U1A is connected with the first sliding pin 1A, and R4 is connected in parallel on the connecting line between the two; R4 is grounded; the No.1 pin of U1A is connected with R3 and the gate of Q15 in sequence; the source of Q15 is connected with R7 and the No.2 pin of U1A; R7 is grounded; the drain of Q15 is connected with the primary of T1; the primary of T1 is connected with the power conversion module and is connected in parallel with D1.

[0064] When the patient is treated, the single-chip microcomputer generates a pulse through the OUT pin to control the turn-on and turn-off of Q1; when turned on, the voltage at the emitter of Q1 is supplied to the No.4 pin of U1A through the No.3 pin to control the operation of U1A; when not turned on, U1 stops working, thereby controlling the frequency and pulse width of the output waveform. The first sliding pin 1A generates and outputs the subdivided voltage check_1 to U1A; U1A cooperates with Q15 and R7 to generate a constant current amplification output through the No.1 pin; the primary of T1 stores energy when Q15 is turned on and outputs a pulse wave through the secondary coupling to provide energy output and a heavy insulation isolation for the patient application module 6.

Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
