Description

Technical Field

[0001] The present invention relates to the technical field of therapeutic medical devices, and in particular to a wearable pain management device. Background Art

[0002] Pain not only affects the quality of life, but also causes psychological illness if long-term pain is not effectively treated. The International Association for the Study of Pain (IASP) defines pain as: an unpleasant sensation and emotional experience associated with actual or potential tissue damage, or similar. Common pain includes: chronic pain, acute pain, postoperative pain, cancer pain, etc., such as headache, toothache, neck pain, various joint pain, various neuralgia, spinal pain, back pain, myalgia, labor pain, sports injury pain, various cancer pain, etc. At present, there are two main ways to treat pain: drug therapy and physical therapy. Pain relief drugs are divided into three categories: non-opioid analgesics, opioid analgesics, and auxiliary analgesics. Non-opioid analgesics, such as aspirin, acetaminophen, ibuprofen, ketoprofen, etc., are usually effective for mild to moderate pain. Opioid analgesics, such as morphine, fentanyl, etc., are the most effective analgesics and are effective for different types of pain. Auxiliary analgesics work by changing the way nerves process pain. Commonly used ones include antidepressants and anti-epileptic drugs. Common physical pain relief methods include: direct cold or hot compresses on the painful area, electrical stimulation of nerve regulation, acupuncture, massage, etc. Among them, the efficacy of acupuncture analgesia in traditional Chinese medicine has been widely recognized at home and abroad. Among acupuncture analgesia therapies, wrist-ankle acupuncture therapy has won praise from medical workers and patients for its advantages such as being simple to learn, easy to operate, safe and painless, significant analgesic effect, and low cost.

[0003] Wrist-ankle acupuncture was invented by Professor Zhang Xinshu of Changhai Hospital affiliated to the Second Military Medical University from 1966 to 1975 after a large amount of clinical practice verification. It was named because it only performs subcutaneous acupuncture on the wrist and ankle to treat diseases.

[0004] The basic method of wrist-ankle acupuncture is: divide both sides of the body including the limbs into 6 longitudinal zones, set one acupuncture point in each of the 6 longitudinal zones at the wrist and ankle, and number the longitudinal zones and the corresponding acupuncture points with the same number from 1 to 6; draw a horizontal line in the middle of the body, which is equivalent to the diaphragm, to divide the body into upper and lower halves, and if the pain is in the upper body, use acupuncture points at the wrists; if the pain is in the lower body, use acupuncture points at the ankles; select acupuncture points with the same number according to the area where the symptom is located; use shallow subcutaneous needling, and require that no soreness, swelling, numbness or pain should occur at the acupuncture site.

[0005] Physical analgesia therapies such as electrical stimulation, acupuncture, and massage require patients to go to medical institutions for treatment by doctors. For patients at home, they need to travel back and forth between the hospital and home, which causes inconvenience and fails to solve the problem of easy access to analgesia treatment and reduce treatment costs.

[0006] For wrist and ankle acupuncture analgesia, although the needle can be left subcutaneously for more than 24 hours for analgesia, the patient's daily activities will be affected and the skin at the needle site may also be infected. Vigorous activities may cause the acupuncture needle to bend or even break, leading to damage to muscle tissue or blood vessels. Summary of the invention

[0033] The ultrasonic treatment head 2 comprises a shell 21, an ultrasonic transducer 22 is arranged inside the shell 21, a mounting seat 23 is arranged on one side of the ultrasonic transducer 22, a thermistor 24 is arranged on the ultrasonic transducer 22, an inverted ring 25 is arranged on the outer surface of the shell 21, and a wire outlet hole 26 is arranged on the inverted ring 25;

[0034] The mounting seat 23 is made of engineering plastics (such as ABS, PC) or metal materials (such as stainless steel, aluminum alloy), meets the requirements of biocompatibility, can directly contact with human skin, play the role of electrical safety isolation, and protect the ultrasonic transducer 22. At the same time, the ultrasonic wave can smoothly pass through the mounting seat 23; the ultrasonic wave emitted by the ultrasonic transducer 22 can enter the human tissue through the mounting seat 23; a part of the heat generated by the ultrasonic transducer 22 when working can be conducted into the mounting seat 23 and diffused into the surrounding environment through the mounting seat 23. The ultrasonic transducer 22 is composed of a piezoelectric element and a metal electrode. The piezoelectric element is a sheet of piezoelectric ceramic ( For example: PZT piezoelectric ceramics) or piezoelectric composite materials (for example: 1-3 type piezoelectric composite materials), the upper and lower surfaces of the piezoelectric element are attached with extremely thin metal electrodes (for example: silver plating layer), and the upper and lower electrodes are connected to the corresponding wires in the cable harness by welding. The ultrasonic transducer 22 is fixed to the side of the mounting seat 23 facing away from the skin by bonding (for example: using epoxy glue). In order to prevent the temperature of the contact surface between the mounting seat 23 and the patient's wrist and ankle from being too high to cause burns (safety regulations require that the temperature here should not exceed 41°C), a thermistor 24 is installed in the mounting seat 23 and next to the ultrasonic transducer 22 to detect the temperature around the ultrasonic transducer 22. The two pins of the thermistor 24 are connected to the corresponding wires in the cable harness by welding.

[0035] The mounting base 23 is tightly bonded to the housing 21 by an adhesive (e.g., epoxy glue), and the ultrasonic transducer 22 and thermistor 24 are encapsulated in the housing. The cable harness passes through the outlet hole 26 on the housing 21 to the outside of the housing 21. There is also a buckle ring 25 on the housing 21, which cooperates with the corresponding mounting hole on the wrist-ankle elastic ring 1 to install and fix the ultrasonic treatment head 2 to the wrist-ankle elastic ring 1;

[0036] The driving module 3 includes a driving module housing 31, a transducer driving module 32 is arranged inside the driving module housing 31, a power module 33 is arranged on one side of the transducer driving module 32, and a control and display module, a power switch, a power socket and a signal connector are arranged on the driving module housing 31;

[0037] The power cord is connected to the power socket to connect to the mains electricity to power the drive module 3 or to charge the lithium-ion battery in the power module 33 .

[0038] The user can select the analgesic site, set the duration of analgesic treatment, and select the stimulation intensity according to the degree of pain through the control and display module.

[0039] The ultrasonic transducer driving module 32, according to the pain site selected by the user, the set analgesic treatment duration and stimulation intensity information, controls the frequency synthesis chip to provide a driving signal to the power amplifier circuit by the main control single chip, and changes the output power of the power amplifier circuit by adjusting the input voltage of the power amplifier circuit, outputs a driving signal to the ultrasonic transducer 22 on the stimulation point corresponding to the pain site through the signal connector and the cable, and stimulates the transducer to emit a 3MHz pulse ultrasonic wave to the stimulation point for analgesic treatment. The built-in no-load protection circuit of the driving module 3 can sample the voltage value between the upper and lower electrodes of the ultrasonic transducer 22 in real time. If the mounting seat is not close to the stimulation site, the ultrasonic transducer 22 will heat up and cause the voltage between the electrodes to increase. After the no-load protection circuit detects the increased abnormal voltage, the driving module 3 will suspend the output of the driving signal, and send an alarm message to the control and display module, indicating that the ultrasonic treatment head at this place is not closely attached to the skin.

[0040] The drive module 3 can be configured in various forms:

[0041] For example, the driving module 3 is a host placed beside the bed, with four signal connectors on it, which are respectively connected to the ultrasonic treatment head 2 in the right wrist elastic ring 11, the left wrist elastic ring 12, the right ankle elastic ring 13 and the left ankle elastic ring 14 through four cables to perform ultrasonic stimulation on the stimulation points to implement analgesia treatment;

[0042] For example, the driving module 3 is a host computer attached to the patient's waist belt, on which there are four signal connectors, which are respectively connected to the ultrasonic treatment head 2 in the right wrist elastic ring 11, the left wrist elastic ring 12, the right ankle elastic ring 13 and the left ankle elastic ring 14 through four cables to perform ultrasonic stimulation on the stimulation points to implement analgesic treatment;

[0043] A preferred embodiment of the present invention is to make the driving module 3 into four small hosts (upper right host, upper left host, lower right host, lower left host). The upper right and upper left hosts are respectively worn on the right forearm and left forearm of the patient through a strap 4, and are respectively connected to the ultrasonic treatment head 2 in the right wrist elastic ring 11 and the left wrist elastic ring 12 through cables; the lower right and lower left hosts are respectively worn on the right calf and left calf of the patient through a strap, and are respectively connected to the ultrasonic treatment head 2 in the right ankle elastic ring 13 and the left ankle elastic ring 14 through cables. Bluetooth communication can be used between the four small hosts, and the analgesic site can be selected, the analgesic treatment duration and the stimulation intensity can be set through one small host.

[0044] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents.
