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

[0031] To facilitate the first driving device 300 to drive the rotating member 200, the rotating member 200 is formed with a first rotating guide slot 210, and the first driving device 300 is arranged on the fixed member 100. The first driving device 300 can drive the rotating member 200 to rotate around the first shaft 600 relative to the fixed member 100 by the movement of the output end 310 of the first driving device 300 cooperating with the first rotating guide slot 210. More specifically, the first driving device 300 is an electric motor, which can drive the output end 310 of the first driving device to rotate. Specifically, the ultrasonic device further comprises a transmission mechanism, and the output end of the first driving device is threadedly connected to the first rotating guide slot through the transmission mechanism to drive the rotating member to rotate around the first shaft relative to the fixed member. More specifically, the transmission mechanism comprises a gear arranged on the output end 310 of the first driving device, and the first rotating guide slot 210 is provided with a gear or formed with a toothed groove. The first driving device drives the rotating member 200 to rotate by cooperating with the gear. More specifically, the transmission mechanism comprises a first helical gear on the output end 310 of the first driving device and a second helical gear on the fixed member, and the first rotating guide slot 210 is provided with a gear or formed with a toothed groove. The first driving device can drive the rotating member 200 to rotate by cooperating with the first helical gear, the second helical gear and the gear or the toothed groove on the first rotating guide slot 210. Of course, in some embodiments, the output end of the first driving device can also be moved forward and backward, such as a step lead screw motor, to drive the rotating member 200 to rotate by other means. Since there are various ways to drive the article to rotate by the electric motor, the present disclosure does not limit this.

[0032] The rotating member 200 is formed with a second rotating guide slot 220, and the second driving device 400 is connected to the ultrasonic detection mechanism 500. The output end 410 of the second driving device is installed in the second rotating guide slot 220. The second driving device 400 can drive the ultrasonic detection mechanism 500 to rotate around the second shaft 700 relative to the rotating member 200 by the movement of the output end 410 of the second driving device cooperating with the second rotating guide slot 220. More specifically, the second driving device 400 is an electric motor, which can drive the output end to move forward and backward in a second direction. The second direction is specifically the direction of the second driving device 400 towards or away from the ultrasonic detection mechanism 500. The second rotating guide slot 220 can be arc-shaped, but not a circular arc, i.e. the distance between each point of the second rotating guide slot 220 and the second shaft 700 is different, so that when the output end 410 of the second driving device moves, the ultrasonic detection mechanism 500 can be driven to rotate under the cooperation with the connecting shaft body. In addition, the second rotating guide slot 220 can be arranged on the sector 230 to facilitate the rotation of the ultrasonic detection mechanism 500.

[0033] It should be noted that the ultrasonic detection mechanism 500 is a structure for detecting by ultrasonic, which means emitting ultrasonic waves to the object and recording the echo of the internal structure of the object. The echo can be 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 pericardial effusion is detected by the ultrasonic probe. At the same time, the shell is connected to the rotating member 200 by a connecting shaft body. Specifically, the connecting shaft body is a cylindrical material, which can be understood as a second shaft 700.

[0034] It should be noted that the first shaft 600 and the second shaft 700 can be a solid structure or a virtual axis, and the present disclosure does not make specific limitations. In some embodiments, the first shaft 600 is a virtual axis. The second shaft 700 can be a connecting shaft body, that is, a cylindrical connecting shaft. In addition, the included angle a between the first shaft 600 and the second shaft 700 can be 85-95. Of course, in some embodiments, the included angle a can be equal to or approximately equal to 90°.

[0035] Optionally, the ultrasonic device further includes a flexible base 800, which is arranged below the fixed member 100. In addition, in some optional embodiments, the lower surface of the flexible base 800 is coated with organic silicon. In the above scheme, the flexible base 800 is arranged to be non-invasively attached to the skin surface of the subject, which facilitates real-time monitoring of pericardial effusion. Specifically, the flexible base 800 can be made of silicone, which has a certain shape, but can also deform under the action of a certain force. Optionally, the area of the flexible base 800 projected on the horizontal plane is larger than the area of the fixed member 100, the rotating member 200, etc. projected on the horizontal plane, so the flexible base 800 is wider to make the ultrasonic device can be relatively stably placed in front of the patient's chest. When performing ultrasonic detection, a coupling agent is needed. However, the general coupling agent is water-based ultrasonic gel, which will evaporate over time. Therefore, the present disclosure coats liquid organic silicon on the flexible base 800 as a coupling agent.

[0036] In some alternative embodiments, the ultrasound device further comprises a puncture needle 920 and a needle guide 910, the needle guide 910 is arranged on the fixing member 100, and the puncture needle 920 is arranged in the needle guide. Specifically, the needle guide 910 is arranged on the rear side of the fixing member 100 and on the flexible base 800. The needle guide 910 is internally formed with a cavity to accommodate the puncture needle 920 and allow the puncture needle 920 to move. In addition, in the embodiment with the flexible base 800, the flexible base 800 is provided with a through hole at a position corresponding to the puncture needle 920, so that the puncture needle 920 can pass through. More specifically, the needle guide is formed with a guide channel, the puncture needle 920 is installed on a needle fixing member 930, the needle fixing member 930 is formed with a guide protrusion 931, and the puncture needle 920 is moved 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 in the first position, the puncture needle 920 does not protrude out of the needle guide and does not penetrate into the patient's body. When the puncture needle 920 is in the second position, the puncture needle 920 protrudes out of the needle guide and can penetrate into the patient's body. Specifically, the guide channel includes a first channel 911 extending in the up-down direction and a second channel 912 extending in the up-down direction. The top of the first channel 911 and the top of the second channel 912 are communicated, so that 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 (i.e., the puncture needle 920 is in the first position), the puncture needle 920 cannot protrude out of the needle guide. When the guide protrusion 931 is located at the bottom of the second channel 912 (i.e., the puncture needle 920 is in the second position), the puncture needle 920 can protrude out of the needle guide. It should be noted that when the patient has pericardial effusion and lies down, the coverage area of the pericardial effusion is large, and the puncture needle 920 can be inserted into the patient's body in a general range to extract the pericardial effusion.

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

[0038] In some alternative embodiments, the ultrasound device further comprises a wireless transmission device, which is in signal connection with the ultrasound detection mechanism 500. The wireless transmission device can be a Bluetooth, Wifi or other wireless transmission device. The image data obtained by the ultrasound detection mechanism 500 can be transmitted to the computer of the nurse or doctor through the wireless transmission device, so as to be monitored by the nurse or doctor in real time. It should be noted that in some embodiments, the ultrasound device can not be provided with a wireless transmission device, and can also be connected to the computer or other processing devices outside through a wire harness.

[0039] In implementation, as shown in Figure 9 The doctor or nurse first lays the patient H flat, then places the ultrasound device in front of the chest of the patient H, approximately the position of region A. Then, the first driving device 300 and the second driving device 400 are started to drive the ultrasound detection mechanism 500 to scan in 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 doctor can monitor the conditions of multiple patients at the same time. Once the presence of pericardial effusion is found, early intervention can be performed.

[0040] The ultrasound device of the utility model can be attached to the skin surface of the examinee noninvasively, used for real-time monitoring of pericardial effusion, and has the 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 attached design of the flexible base 800 makes the ultrasound device can be attached to the skin of the chest, and the patient has good compliance for long-term wearing; (2) the ultrasound probe can realize 360° automatic rotation, ensuring the effectiveness of monitoring and collecting images; (3) it is not necessary to arrange an operator to continuously hold the device or to fix it complicatedly, the image data is uploaded to the doctor and nurse end in real time, saving labor cost; (4) the contact surface uses liquid organic silicon instead of water-based ultrasound gel which evaporates over time as a coupling agent, 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 pericardial tamponade occurs, even if the on-duty doctor has no pericardial puncture experience, he can also directly use the matching internal puncture needle 920 to perform rescue.

[0041] In the description of the embodiments of the present application, it should be further pointed out that, unless otherwise explicitly specified and limited, the terms "set", "provided with", "connected" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meanings of the above-mentioned terms in the present application can be understood according to the specific circumstances.
