Description

Technical Field

[0001] The invention discloses a heating acupuncture needle and a heating system, belongs to the technical field of acupuncture needles, and specifically relates to a precise targeted heating acupuncture needle and a heating system. Background Art

[0002] Acupuncture is a very common treatment method in traditional Chinese medicine and is widely praised by patients in clinical practice. Acupuncture has a good analgesic effect and can effectively relieve headaches, pillow falls, cervical spondylosis, arthritis and other diseases.

[0003] Acupuncture needles usually consist of a needle body, a needle tip, a needle handle and / or a cannula. The front end of the needle body is the needle tip, and the back end is the needle handle. The needle body and the needle tip are smooth, while the needle handle is usually threaded. It is used for acupuncture treatment in traditional Chinese medicine.

[0004] In the prior art, acupuncture needles can be heated. Internal heating needle technology is a treatment technology that combines modern constant temperature heating technology with acupuncture loosening. Special needles are used to pierce the acupoints or muscles of the human body, and the needle body is assisted by constant temperature heating of the needle body; such as patent number 202410767445.6, patent name A kind of adjustable self-heating acupuncture needle for warm acupuncture, the acupuncture needle is heated by a temperature control box, but this method of heating is the overall heating of the acupuncture needle, but when working, only the needle head is needed for heating. If the needle body is heated as a whole, other areas except the lesion area will be damaged, thereby greatly affecting the effect of treatment. Therefore, an acupuncture needle that only performs constant temperature heating is needed to solve the above problems. Summary of the invention

[0005] Purpose of the invention: To provide a precise targeted heating acupuncture needle and heating system to solve the above-mentioned problems.

[0006] Technical solution: A precise targeted heating acupuncture needle, comprising: an acupuncture needle, a heating wire, a temperature controller and a power supply;

[0007] The heating wire is installed in the needle head of the acupuncture needle, the heating wire is connected to the power source through a wire, and the temperature controller is connected to the heating wire and the power source through a wire at the same time;

[0008] The controller collects and monitors the temperature of the heating wire, and controls the power supply voltage according to the temperature value to control the heating temperature of the heating wire.

[0009] In a further embodiment, there are multiple acupuncture needles, and each acupuncture needle is provided with a heating wire and a thermocouple. The heating wires and thermocouples in the multiple acupuncture needles are connected to the temperature controller and the power supply in parallel through wires so that the temperature controller can independently control the temperature of the heating wire in each acupuncture needle.

[0010] In a further embodiment, a precise targeted heating acupuncture needle as claimed in any one of claims 1 to 2 is characterized in that the heating system is located in the temperature controller and comprises:

[0011] The lower computer unit collects the ambient temperature in real time through the temperature sensor, connects the temperature sensor to the circuit, converts the temperature into an output digital signal by using the sensor, and displays the temperature information on the single-chip computer display screen through the single-chip computer. The lower computer unit is composed of a temperature sensor and a signal processing unit, an A / D conversion sampling unit, a central control unit, a temperature control unit and a display unit;

[0012] The host computer unit is implemented using LabVIEW software to display the collected temperature data changes and temperature curves in real time on the display screen, and save them in the computer for easy query and analysis as well as intelligent control of the temperature acquisition module;

[0013] A heating system for accurately targeting and heating acupuncture needles, wherein the temperature sensor is used to collect the temperature of the heating wire in each acupuncture needle as the ambient temperature collection and digital output;

[0014] The signal processing unit is used to process the signal collected by the temperature sensor;

[0015] The A / D conversion sampling unit is used to convert the analog signal collected by the temperature sensor into a digital signal;

[0016] The central control unit is used to control each unit and connect to the host computer for communication;

[0017] The temperature control unit uses a single-chip microcomputer as the core unit for controlling the system temperature, and performs automatic temperature control through the single-chip microcomputer program.

[0018] The display unit is used to display the temperature of the heating wire in each acupuncture needle.

[0019] In a further embodiment, a calibration module is provided in the lower computer unit, and the calibration module calculates the temperature uniformity according to the displayed temperature average value and the measured temperature average value before each operation, thereby determining the difference between the highest temperature and the lowest temperature according to the temperature uniformity to obtain the temperature deviation, thereby performing temperature calibration;

[0020] The calibration module first calculates the difference between the average displayed temperature and the average measured temperature at the center of the calibration plane:

[0021] Δt=t1-t2

[0022] Where Δt is the temperature uniformity, t1 is the average displayed temperature, and t2 is the average measured temperature. Temperature uniformity refers to the arithmetic mean of the difference between the highest and lowest temperatures measured at each position during the test when the equipment is in a stable operating state:

[0023]

[0024] Where Δt1 is the temperature deviation, t imax is the highest temperature of each acupuncture needle measured at the i-th time, t imin is the lowest temperature of each acupuncture needle measured at the i-th time, and n is the number of measurements;

[0025] Temperature fluctuation refers to the temperature change over time when the equipment is in a stable operating state, that is, half of the difference between the highest and lowest temperatures measured during the measurement process:

[0026]

[0027] Where Δt2 is the temperature fluctuation, t omax is the highest temperature among n measurements, t omin is the lowest temperature among n measurements of the center point;

[0028] The final temperature deviation and temperature fluctuation are obtained by calculation and sent to the central control unit, which performs adjustments.

[0029] In a further embodiment, the temperature sensor collects n data as a standard and circulates at a time, and inputs them into the signal processing unit, and the signal processing unit processes the data using an arithmetic average method to obtain a more accurate temperature analog signal and inputs it into the A / D conversion sampling unit, and the A / D conversion sampling unit linearizes and compensates these analog signals, converts these digital signals and outputs them to the central control unit:

[0030]

[0031] Where, T represents Celsius temperature (°C), S T Represents the temperature digital signal.

[0032] In a further embodiment, the central control unit compares the digital signal output by the A / D conversion sampling unit with the standard value, performs body adjustment through the temperature control unit, and the display unit displays at the same time. The temperature control unit controls the H-bridge drive through the PID algorithm to perform fast and high-precision temperature control. First, the collected temperature value is substituted into the PID formula through a certain proportional operation to obtain the control variable result:

[0033]

[0034] In the formula, u(t) is the control quantity output by the central control unit; Δt1 is the deviation signal, which is equal to the difference between the given quantity and the output quantity; K p is the proportionality coefficient; T i is the integration time constant; T d is the differential time constant;

[0035] Outputting the results to the H-bridge driver can achieve fast and high-precision temperature control.

[0036] In a further embodiment, the H-bridge driver includes two half-bridge drivers with programmable dead time and two pairs of MOS tubes. The half-bridge driver adds the temperature plus and temperature minus PWM signals emitted by the central control unit to the dead time and outputs two pairs of PWM signals with opposite polarities to enhance its driving capability so that the signal drives the gate of the subsequent MOS tube. At this time, the MOS tube can achieve a faster switching speed and enter the saturation region faster, thereby reducing switching losses and improving output efficiency.

[0037] In a further embodiment, the H-bridge driver includes a MOS transistor Q3, a MOS transistor Q4, a MOS transistor Q5 and a MOS transistor Q6;

[0038] The two teams of MOS tubes are used to control the direction of the temperature control load current. When MOS tubes Q3 and Q6 are turned on, the current flows from the positive end to the negative end of the temperature control load, a forward current flows through the temperature control load, and the temperature begins to decrease. When MOS tubes Q4 and Q5 are turned on, the current flows from the negative end to the positive end of the temperature control load, a reverse current flows through the temperature control load, and the temperature begins to increase.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] The present invention installs a heating wire and a thermocouple in the needle head of an acupuncture needle, the heating wire is connected to a power source through a wire, and a temperature controller is simultaneously connected to the heating wire, the thermocouple and the power source through a wire, so that the present invention only heats the needle head during heating, thereby reducing damage to other parts, thereby greatly improving the heating accuracy.

[0041] The present invention adopts a temperature controller to control and store temperature, a lower computer to collect, process, calculate and adjust temperature, and an upper computer to record in real time, thereby ensuring the accuracy of temperature and facilitating later management and viewing.

[0065] The calibration module first calculates the difference between the average displayed temperature and the average measured temperature at the center of the calibration plane:

[0066] Δt=t1-t2

[0067] Where Δt is the temperature uniformity, t1 is the average displayed temperature, and t2 is the average measured temperature. Temperature uniformity refers to the arithmetic mean of the difference between the highest and lowest temperatures measured at each position during the test when the equipment is in a stable operating state:
