[0002] Currently, diaphragm pacemakers and diaphragm ultrasound are two independent devices. When used, they can only perform phrenic nerve electrical stimulation or diaphragm ultrasound separately. The two cannot be implemented simultaneously and continuously. There is a lack of real-time evaluation and continuous monitoring of the effectiveness of diaphragm stimulation, and it is impossible to provide real-time feedback and adjust the level of electrical stimulation treatment based on the monitoring results. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing diaphragm pacemaker and diaphragm ultrasound cannot be implemented simultaneously, and feedback and adjustment of the electrical stimulation treatment level cannot be performed in time.

[0004] In order to solve the above technical problems, the technical solution of the present invention is to provide a diaphragm ultrasound-guided patch-type diaphragm pacemaker, including a host, a sensor and an electrode sheet. The sensor and electrode sheet are arranged on the outside of the host, and the host is equipped with an ultrasound imaging module, a diaphragm function evaluation module, a diaphragm pacing control module and an interactive display module. The sensor is connected to the ultrasound imaging module, the ultrasound imaging module and the diaphragm pacing control module are both connected to the interactive display module and the diaphragm function evaluation module, and the electrode sheet is connected to the diaphragm pacing control module.

[0005] Optionally, the diaphragm function assessment module includes an image processing module, a data processing module and a data analysis module connected in sequence, the ultrasound imaging module is connected to the image processing module, and the data analysis module is connected to the diaphragm pacing control module.

[0007] A method for using a diaphragm ultrasound-guided patch-type diaphragm pacemaker comprises the following steps:

[0008] Step 1: Place the small electrode on the lower 1 / 3 of the outer edge of the sternocleidomastoid muscle and the large electrode on the midclavicular line and the second intercostal space. Place one sensor along the right midclavicular line approximately 2 cm above the lowest rib, and the other sensor between the patient's right anterior and midaxillary lines.

[0009] Step 2: Set the initial diaphragm pacing stimulation intensity, number of pacing times, stimulation frequency, treatment time, and treatment target on the interactive display module of the host;

[0010] Step 3: The diaphragm pacing control module electrically stimulates the patient through the electrodes;

[0011] Step 4: The ultrasound imaging module obtains the patient's diaphragm structure and transmits it to the diaphragm function assessment module;

[0012] Step 5: The diaphragm function assessment module calculates the diaphragm mobility and thickening rate and compares them with the threshold values ​​of mobility and thickening rate;

[0013] Step 6: The diaphragm pacing control module adjusts the electrical stimulation level according to the comparison structure;

[0014] Step 7: Repeat steps 4 to 6 until the treatment is completed.

[0015] Optionally, step 5 includes the following steps:

[0016] Step 5.1: The image processing module identifies the thickness, thickening rate, mobility and movement rate of the diaphragm based on the diaphragm image transmitted by the ultrasound imaging module;

[0017] Step 5.2: The data processing module calculates the diaphragm thickness and the range of diaphragm movement at the end of inspiration and expiration based on the morphological changes of the diaphragm image, thereby calculating the diaphragm thickening rate and mobility;

[0018] Step 5.3: The data analysis module compares the thickening score and mobility calculated in step 5.2 with a predetermined threshold.

[0019] Optionally, in step 5, the threshold value of the diaphragm thickening rate is 29%, and the threshold value of the diaphragm mobility is 1 cm.

[0020] Optionally, in step 6, the electrical stimulation gear of the diaphragm pacing control module includes five gears from low to high. If the patient's diaphragm mobility and diaphragm thickening rate are both lower than the threshold, the diaphragm pacing control module automatically increases the intensity gear from low to high until the patient's diaphragm mobility and thickening rate reach the threshold; if the patient's monitored diaphragm mobility and thickening rate are not lower than the threshold, it runs at the lowest gear; if the patient's diaphragm ultrasound monitoring effect is not good, it runs according to the preset diaphragm pacing intensity gear.

[0021] In summary, the present invention integrates diaphragm ultrasound and an external diaphragm pacemaker, which can provide real-time feedback and adjust the level of external phrenic nerve stimulation under reliable and continuous diaphragm ultrasound monitoring, thereby improving the efficiency of diaphragm electrical stimulation and achieving the effect of individualized adjustment of the diaphragm electrical stimulation level for each patient.

[0026] Example

[0027] The method for using the diaphragm ultrasound-guided patch-type diaphragm pacemaker of the present invention comprises the following steps:

[0028] Step 1: Place the small electrode on the lower 1 / 3 of the outer edge of the sternocleidomastoid muscle, and the large electrode on the midclavicular line and the second intercostal space. Place one sensor 2 along the right midclavicular line, approximately 2 cm above the lowest rib. Place the other sensor 2 between the patient's right anterior axillary line and mid-axillary line.

[0029] Specifically, one sensor 2 is located between the right midclavicular line and the anterior axillary line at the junction of the costal arch, and continuously measures the movement trajectory of the patient's diaphragm from inspiration to expiration to calculate the diaphragm movement. The other sensor 2 is located between the right anterior axillary line and the mid-axillary line, at the junction of the lung and liver, and continuously measures the thickness of the diaphragm from inspiration to expiration to calculate the diaphragm thickness and thickening rate.

[0030] Step 2: Set the initial diaphragm pacing stimulation intensity, number of pacing times, stimulation frequency, treatment time, and treatment target on the interactive display module 14 of the host 1, and set safety restrictions, such as maximum stimulation intensity, frequency, and duration, to prevent unnecessary harm to the patient. Continuously monitor the patient's vital signs during treatment to ensure treatment safety.

[0031] Step 3: The diaphragm pacing control module 13 electrically stimulates the patient through the electrode sheet 3;

[0032] Step 4: The ultrasound imaging module 11 obtains the patient's diaphragm structure and transmits it to the diaphragm function assessment module 12, and displays the ultrasound image in real time on the interactive display module 14 for easy observation by the operator;

[0033] Step 5: The diaphragm function assessment module 12 calculates the diaphragm mobility and thickening rate, and compares them with the thresholds of mobility and thickening rate;

[0034] Step 5.1: The image processing module 121 identifies key parameters of the diaphragm, such as thickness, thickening rate, mobility, and movement rate, based on the diaphragm image transmitted by the ultrasonic imaging module 11;

[0035] Step 5.2: The data processing module 122 calculates the diaphragm thickness and the range of movement of the diaphragm at the end of inspiration and expiration based on the morphological changes of the diaphragm image, thereby calculating the diaphragm thickening rate and mobility;

[0038] Step 6: The diaphragm pacing control module 13 adjusts the electrical stimulation gear according to the comparison structure;

[0039] Specifically, the electrical stimulation gear of the diaphragm pacing control module 13 includes five gears from low to high. If the patient's diaphragm mobility and diaphragm thickening rate are both lower than the threshold, the diaphragm pacing control module 13 automatically increases the intensity gear from low to high until the patient's diaphragm mobility and thickening rate reach the threshold; if the patient's monitored diaphragm mobility and thickening rate are not lower than the threshold, the lowest gear is used; if the patient's diaphragm ultrasound monitoring effect is not good, the preset diaphragm pacing intensity gear is used;
