[0002] Venous thromboembolism (VTE) includes deep vein thrombosis (DVT) and pulmonary thromboembolism (PTE). The current mainstream mechanical prevention of venous thromboembolism (VTE), including graded compression stockings, intermittent pneumatic compression pumps, and plantar venous compression pumps, all have certain limitations. Neuromuscular electrical stimulation (NMES) is a new type of wearable electronic device, which is one of the low-frequency electrotherapy methods of wearable devices. Its working principle is to use the electrical excitability of nerve cells to stimulate the nerves that control muscles through pulsed current to cause muscle contraction. It has been proven that it can effectively prevent VTE by improving local blood flow and reducing blood stasis.

[0003] At present, there are existing technologies such as a high-energy stimulator (CN113181551A) that uses neuromodulation technology to prevent deep vein thrombosis. While performing neuromodulation and electrical stimulation treatment on the common peroneal nerve in the lower leg to prevent deep vein thrombosis, the electric drive module drives two pull ropes to reciprocate and pull the special electrode belt in the direction of the host mechanism to micro-twist the surface skin and subcutaneous tissue of the common peroneal nerve in the lower leg, thereby accurately locating the nerves in the treatment area and relieving the paralysis of the common peroneal nerve caused by electrical stimulation. However, its mechanical structure is cumbersome, the operation process is complicated, it cannot be digitized and intelligent, and the user experience is poor. Summary of the invention

[0023] like Figure 1 As shown, the present invention provides an intelligent wearable digital neuromuscular stimulator for preventing deep vein thrombosis, including an electrical stimulator, a charging compartment and electrode sheets.

[0025] The magnets include an upper cover magnet 1-3 and a lower cover magnet 1-5, which are respectively installed on the same side of the upper cover and the lower cover. One side of the upper cover and the lower cover is connected by a turn 1-7, and the other side opening direction is connected by the upper cover magnet 1-3 and the lower cover magnet 1-5. The upper cover lining 1-2 is installed inside the upper cover 1-1, and the lower cover lining 1-4 is installed inside the lower cover 1-9, which is used to place the electric stimulator and has a magnet. The charging circuit board 1-6 and the first battery 1-8 are both installed between the lower cover lining 1-4 and the bottom of the lower cover 1-9. The first battery 1-8 is located below the charging circuit board 1-6 and is connected to the charging circuit board circuit. The charging circuit board 1-6 has a charging interface exposed on the outside of the charging compartment.

[0026] The storage platform is used to record the working time and stimulation intensity of the electric stimulator and the relevant data of the detection results of the B-ultrasound component, and upload the patient data to the cloud platform via Bluetooth or wireless network;

[0027] The electric stimulator includes a PCB circuit board, a second battery, a screen and an electrode connector; one end of the electrode connector is connected to the PCB circuit board through an electrode conductive needle, and the other end has a magnet for attracting the magnet in the electrode sheet or the magnet in the lining of the lower cover; the second battery and the PCB circuit board are connected through a circuit for supplying power to the PCB circuit board, and the second battery is also connected to the first battery in the charging compartment through the circuit of the PCB circuit board and the electrode conductive needle for charging the second battery.

[0028] like Figure 2 As shown, the electrode sheet includes an electrode sheet body 2-2, an elastic band 2-11, a magic hook 2-1, an electrode sheet fixing upper cover 2-12, a surface impedance detection electrode 2-3, an output electrode 2-7, a reference electrode 2-10, a gel, a flexible B-ultrasound electrode module 2-9, an electrode sheet magnet 2-5 and an electrode sheet fixing lower cover 2-6.

[0029] The surface impedance detection electrode 2-3, the output electrode 2-7 and the reference electrode 2-10 are installed on the lower side of the electrode sheet body 2-2. The surface impedance detection electrode 2-3 is used to determine whether the electrode sheet assembly is in contact with the skin through impedance detection. The electrode sheet fixing upper cover 2-12 and the electrode sheet fixing lower cover 2-6 are concentrically aligned, and the electrode sheet body 2-2 and the joints of the three electrodes are pressed and fixed by snap connection. The joints of the three electrodes are connected to the electrode conductive needles. The electrode sheet magnet 2-5 is installed inside the electrode sheet fixing lower cover 2-6, and is used to align and attract with the magnet in the electric stimulator. The first hydrogel 2-4 is installed on the lower side of the surface impedance detection electrode 2-3, and the second hydrogel 2-8 is installed on the lower side of the output electrode 2-7 and the reference electrode 2-10, which are used to fit the skin of the patient's lower limbs. The elastic band 2-11 and the magic hook 2-1 are installed on both sides of the electrode sheet fixing upper cover on the upper part of the electrode sheet body. The back of the elastic band 2-11 has magic hair, which is used to cooperate with the magic hook 2-1 to tie the electrode sheet assembly to the patient's lower limbs.

[0030] The flexible B-ultrasound electrode module 2-9 includes a plurality of B-ultrasound probes 2-9-1 forming a rectangular array, which are installed together on the flexible B-ultrasound electrode sheet 2-9-2 and electrically connected to the PCB circuit board in the electrical stimulator through the electrode conductive needle. Based on the flexible B-ultrasound technology detection, the array-shaped ultrasonic transducer is used to collect blood vessel images, calculate the blood flow velocity and flow, and record the peak value. If the blood flow velocity and flow are abnormal, it can be considered that there is suspected thrombosis and further diagnosis is required.

[0031] The use process of the intelligent wearable digital neuromuscular stimulator for preventing deep vein thrombosis provided by the present invention is as follows:

[0032] Users can scan the QR code through the mobile phone mini program to enter the operation control system and enter the patient information for identity binding. The information includes the patient's name, medical record number, inpatient ward, and the VTE risk level recognized by the hospital, etc.

[0033] After binding, the neuromuscular stimulator provided by the present invention will intelligently allocate preventive measures based on the VTE risk level according to the patient information. For low-risk patients, prevention is performed twice a day (am8:30\pm20:30); for medium-risk patients, prevention is performed three times a day (am8:30\pm14:30\pm20:30); for high-risk patients, prevention is performed 3-4 times a day (am6:30\am11:30\pm16:30\pm21:30. The operation control system has a timed reminder function, which actively reminds the patient 5 minutes in advance according to the assigned preventive measures.

[0034] The patient takes out the electric stimulator from the charging compartment, puts on the electrode sheet, and sucks the electric stimulator and the electrode sheet together. The stimulation intensity and working time are set based on the operation control system, and the electric stimulator starts working. After the work is completed, the electric stimulator is returned to the charging compartment for charging in preparation for the next work. If the electrode sheet detects that it is not attached to the human body or suspected of thrombosis, it will not work, and the operation control system will sound an alarm to remind the patient to attach the electrode sheet to the human body or go to the hospital for bilateral lower limb screening as soon as possible. The main unit of the electric stimulator is put back into the charging compartment, and the stimulation data is not recorded.

[0035] After the electric stimulator host is put back into the charging case, the relevant data of the working time period can be uploaded to the storage platform built into the charging case. The storage platform uploads the patient data to the cloud platform via Bluetooth or wireless network and waits for technical personnel to process. The platform technicians regularly classify the patient data, process it according to the severity, and provide timely feedback to the corresponding hospital, so that patients at risk can be notified in time to go to the corresponding hospital for treatment.

[0036] The above embodiments are used to illustrate the present invention rather than to limit the present invention. Any modification and change made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
