[0002] Globally, heart disease is the leading cause of death and disease burden. With the rapid development of cardiac interventional therapy technology, it has been widely used in the clinical treatment of various heart diseases, greatly improving the prognosis and quality of life of patients. Since cardiac interventional therapy is an invasive procedure, the intraoperative operation may damage certain structures of the heart. These surgeries may cause pericardial effusion, which in turn endangers the patient's life. Therefore, once a large amount of pericardial effusion or even pericardial tamponade occurs, emergency bedside pericardiocentesis is required to extract fluid to save lives.

[0003] Currently, the devices that can be used clinically for bedside monitoring of pericardial effusion still have shortcomings, such as the inability to monitor in real time for a long time, difficulty in fitting to the patient, or too narrow a monitoring range. Summary of the invention

[0030] The present disclosure provides an ultrasonic device, including a fixed member 100, a rotating member 200, a first driving device 300, a second driving device 400 and an ultrasonic detection mechanism 500, wherein the rotating member 200 is rotatably installed in the fixed member 100 around a first axis 600, and the ultrasonic detection mechanism 500 is rotatably installed in the rotating member 200 around a second axis 700, the first driving device 300 is used to drive the rotating member 200 to rotate relative to the fixed member 100, and the second driving device 400 is used to drive the ultrasonic detection mechanism 500 to rotate relative to the rotating member 200, wherein the first axis 600 and the second axis 700 form an angle α, 180°>α>0°. For details, see Figure 1 , a mounting groove 110 is formed on the fixed member 100, and the rotating member 200 is installed in the mounting groove 110. The mounting groove 110 limits the rotation of the rotating member 200 in the fixed member 100. Specifically, the mounting groove 110 limits the rotation of the rotating member 200 relative to the fixed member 100 around the first axis 600. More specifically, the rotating member 200 includes a fan-shaped portion 230, a first rotating portion 240 and a second rotating portion 250 connected in sequence from top to bottom, and the first rotating portion 240 is roughly a cylindrical structure. The second rotating portion 250 is roughly a cylindrical structure except that the first rotation guide groove 210 is formed in the middle of the second rotating portion 250. The diameter of the cross section of the second rotating portion 250 is greater than the diameter of the cross section of the first rotating portion 240. The shape of the mounting groove 110 is roughly matched with the shapes of the first rotating portion 240 and the second rotating portion 250 (except for the portion corresponding to the first rotation guide groove 210), so that the rotating member 200 can only rotate around the first axis 600 relative to the fixed member 100. A fan-shaped receiving groove is provided in the fan-shaped portion 230 , and the ultrasonic detection mechanism 500 can be placed in the receiving groove and rotate in the receiving groove.

[0031] In order to facilitate the first driving device 300 to drive the rotating member 200, the rotating member 200 is formed with a first rotation guide groove 210. The first driving device 300 is arranged on the fixed member 100. The first driving device 300 can cooperate with the first rotation guide groove 210 through the movement of the output end 310 of the first driving device to drive the rotating member 200 to rotate relative to the fixed member 100 around the first axis 600. More specifically, the first driving device 300 is a motor, which can drive the output end 310 of the first driving device to rotate. Specifically, the ultrasonic device also includes a transmission mechanism, and the output end of the first driving device is threadedly connected with the first rotation guide groove through the transmission mechanism to drive the rotating member to rotate relative to the fixed member around the first axis. More specifically, the transmission mechanism includes a gear arranged on the output end 310 of the first driving device, and the first rotation guide groove 210 is equipped with a gear or formed with a tooth pattern. The first driving device cooperates with the gear to drive the rotating member 200 to rotate. More specifically, the transmission mechanism includes a first bevel gear on the output end 310 of the first drive device and a second bevel gear on the fixed member, and the first rotation guide groove 210 is provided with a gear or formed with a tooth pattern. Through the cooperation of the first bevel gear, the second bevel gear and the gear or tooth pattern on the first rotation guide groove 210, the first drive device can drive the rotating member 200 to rotate. Of course, in some embodiments, it is not excluded that the output end of the first drive device moves forward and backward, such as a stepping screw motor, and drives the rotating member 200 to rotate in other ways. Since there are many ways to drive an object to rotate by a motor, the present disclosure does not limit this.

[0032] The rotating member 200 is formed with a second rotation guide groove 220, the second driving device 400 is connected to the ultrasonic detection mechanism 500, and the output end 410 of the second driving device is installed in the second rotation guide groove 220. The second driving device 400 can cooperate with the second rotation guide groove 220 to drive the ultrasonic detection mechanism 500 to rotate relative to the rotating member 200 around the second axis 700 through the movement of the output end 410 of the second driving device. More specifically, the second driving device 400 is a motor, which can drive the output end to move forward and backward along the second direction, and the second direction is specifically the direction of the second driving device 400 toward or away from the ultrasonic detection mechanism 500. The second rotation guide groove 220 can be an arc, but not a circular arc, that is, the distances between each point of the second rotation guide groove 220 and the second axis 700 are different, so that when the output end 410 of the second driving device moves, it can drive the ultrasonic detection mechanism 500 to rotate in cooperation with the connecting shaft. In addition, the second rotation guide groove 220 may be provided on the fan-shaped portion 230 to facilitate guiding the rotation of the ultrasonic detection mechanism 500 .

[0033] It should be noted that the ultrasonic detection mechanism 500 is a structure for detection by ultrasound, which means that ultrasonic waves are emitted to an object and echoes of the internal structure of the object are recorded. The echoes can be subsequently processed to form an image to reflect the internal structure of the object. In some optional embodiments, the ultrasonic detection mechanism 500 includes a shell and an ultrasonic probe located inside the shell. The situation of pericardial effusion is detected by the ultrasonic probe. At the same time, the shell is connected to the rotating member 200 through a connecting shaft. Specifically, the connecting shaft is a cylindrical material, and the connecting shaft can be understood as a second shaft 700.

[0034] It should be noted that the first axis 600 and the second axis 700 may be physical structures or virtual axes, and the present disclosure does not impose specific restrictions. For example, in some embodiments, the first axis 600 is a virtual axis. The second axis 700 may be a connecting axis, that is, a cylindrical connecting axis. In addition, the angle α between the first axis 600 and the second axis 700 may be 85° to 95°. Of course, in some embodiments, the angle α may be equal to or approximately equal to 90°.

[0035] Optionally, the ultrasonic device further includes a flexible base 800, which is disposed below the fixing member 100. In addition, in some optional embodiments, the bottom of the flexible base 800 is coated with silicone. In the above scheme, by providing the flexible base 800, it can be attached to the skin surface of the subject without trauma, which is convenient for real-time monitoring of pericardial effusion. Specifically, the flexible base 800 can be composed of silicone, which has a certain shape, but can also be deformed when subjected to a certain force. Optionally, the area of ​​the flexible base 800 projected on the horizontal plane is larger than the area of ​​the fixing member 100, the rotating member 200, etc. projected on the horizontal plane, so the flexible base 800 is wider, so that the ultrasonic device can be placed relatively stably on the patient's chest. When performing ultrasonic testing, it is necessary to apply a coupling agent. However, the general coupling agent is a water-based ultrasound gel, which will evaporate over time. Therefore, the present disclosure uses liquid silicone coated on the flexible base 800 as a coupling agent.

[0036] In some optional embodiments, the ultrasonic device further comprises a puncture needle 920 and a puncture needle guide 910, wherein the puncture needle guide 910 is disposed on the fixing member 100, and the puncture needle 920 is disposed in the puncture guide. Specifically, the puncture needle guide 910 is disposed on the rear side of the fixing member 100 and on the flexible base 800. A cavity is formed inside the puncture needle guide 910 to accommodate the puncture needle 920 and allow the puncture needle 920 to move. In addition, if in an embodiment with a flexible base 800, the flexible base 800 is provided with a through hole at a position corresponding to the puncture needle 920, so as to facilitate the passage of the puncture needle 920. More specifically, a guide channel is formed in the puncture guide, and the puncture needle 920 is mounted on the puncture needle fixing member 930, and a guide protrusion 931 is formed on the puncture needle fixing member 930, and the puncture needle 920 moves between the first position and the second position through the cooperation of the guide protrusion 931 and the guide channel. When the puncture needle 920 is located at the first position, the puncture needle 920 does not extend out of the puncture guide and is not inserted into the patient's body. When the puncture needle 920 is located at the second position, the puncture needle 920 extends out of the puncture guide and can be inserted into the patient's body. Specifically, the guide channel includes a first channel 911 and a second channel 912, the first channel 911 extends in the up-down direction, and the second channel 912 extends in the up-down direction. The first channel 911 and the second channel 912 are connected at their tops, so the guide protrusion 931 can move from the first channel 911 to the second channel 912, thereby driving the puncture needle to move. Secondly, the bottom of the first channel 911 is higher than the bottom of the second channel 912. Therefore, when the guide protrusion 931 is located at the bottom of the first channel 911 (that is, the puncture needle 920 is located at the first position), the puncture needle 920 cannot extend out of the puncture guide. When the guide protrusion 931 is located at the bottom of the second channel 912 (i.e., the puncture needle 920 is located at the second position), the puncture needle 920 can extend out of the puncture guide. It should be noted that when the patient has pericardial effusion and the patient lies flat, the pericardial effusion covers a large area, and the puncture needle 920 can be inserted into the patient's body within a rough range to extract the pericardial effusion.

[0037] In addition, in some optional embodiments, the puncture needle guide 910 can be detachably mounted on the fixing member 100, and the user can take out the puncture needle guide 910 together with the puncture needle 920.

[0038] In some optional embodiments, the ultrasound device also includes a wireless transmission device, which is connected to the ultrasound detection mechanism 500 by signal. The wireless transmission device can be a wireless transmission device such as Bluetooth, Wifi, etc. The image data detected by the ultrasound detection mechanism 500 can be transmitted to the nurse's or doctor's computer through the wireless transmission device, so that the nurse or doctor can monitor in real time. It should be noted that in some embodiments, the ultrasound device may not be provided with a wireless transmission device, and it may be connected to an external computer or other processing device through a wire harness.

[0039] When this plan is implemented, Fig. 9 As shown, the doctor or nurse first lets the patient H lie flat, and then places the ultrasound device on the chest of the patient H, roughly where the area A is located. Then, the first drive device 300 and the second drive device 400 are started, and the ultrasound detection mechanism 500 is driven by the first drive device 300 and the second drive device 400 to scan a large range. The data obtained by the ultrasound detection mechanism 500 can be uploaded to the computer of the nurse or doctor. Therefore, the nurse and the doctor can monitor the conditions of multiple patients at the same time. Once the presence of pericardial effusion is found, intervention can be carried out as soon as possible.

[0040] The ultrasonic device of the present invention can be non-invasively attached to the skin surface of the subject for real-time monitoring of pericardial effusion. At the same time, it is equipped with a real-time uploading function of image data, which can effectively solve the limitations of the above-mentioned existing devices and has the following characteristics: (1) The adhesive design of the flexible base 800 allows the ultrasonic device to be attached to the chest skin, and the patient has good compliance in wearing it for a long time; (2) The ultrasonic probe can achieve 360° full-automatic rotation to ensure the effectiveness of monitoring and collecting images; (3) There is no need to arrange the operator to hold the device continuously or fix it cumbersomely, and the image data is uploaded to the doctor and nurse in real time, saving labor costs; (4) Liquid silicone is used as a coupling agent on the contact surface instead of water-based ultrasonic gel that evaporates over time, and the image is stable; (5) It can be directly uploaded to the monitoring screen terminal in real time through a wireless device, which is convenient for real-time dynamic monitoring of multiple people at the same time; (6) Once an emergency situation of pericardial tamponade occurs, even a doctor on duty who has no experience in pericardial puncture can directly use the matching internal puncture needle 920 to directly perform rescue.

[0041] In the description of the embodiments of the present application, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed", "provided with", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
