Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a portable ultrasonic diagnostic device. Background Art

[0002] Medical ultrasound equipment uses ultrasonic signals for imaging. Compared with X-ray imaging, PET imaging, MR imaging, etc., it has the characteristics of being radiation-free. In addition, medical ultrasound equipment has good portability and low scanning costs, so it has been increasingly widely used.

[0003] Medical ultrasound equipment comes in two types: cart-type and portable. The cart-type has a larger main unit, onto which the probe is plugged, and multiple probes are typically configured. Cart-type ultrasound equipment is heavy, so it requires wheels. When it needs to be moved from one location to another, it can simply be pushed. However, its disadvantage is that its heavy weight makes it inconvenient to move between two long distances. Portable ultrasound equipment is lighter and can be carried around by the user, making it more convenient to use. Furthermore, the price of portable ultrasound equipment is much lower than that of cart-type equipment. Portable ultrasound equipment can be used in remote areas, homes, hospitals where frequent movement is required, and ambulances.

[0004] Existing portable ultrasound devices consist of a main unit and an ultrasound probe connected to the main unit. During use, the user needs to hold the probe in one hand and the main unit in the other. With both hands occupied, it's difficult for the user to operate the main unit during scanning, such as adjusting scanning parameters. Summary of the Invention

[0005] The purpose of this application is to overcome the deficiencies in the prior art and to provide a portable ultrasonic diagnostic device that can operate the host in a timely manner during scanning.

[0007] The probe is connected to the host via a signal connection, and the signal collected by the probe is processed to generate an ultrasonic image and displayed on the display screen;

[0008] A keyboard assembly includes a keyboard and a cover rotatably connected to the keyboard. The cover can be fixed at an angle relative to the keyboard. When the host is not placed on the cover, the ultrasonic diagnostic equipment can be operated and controlled by touch; when the host is placed on the cover, the host and the keyboard are connected by signal, and the ultrasonic diagnostic equipment can be operated and controlled by touch or keyboard.

[0009] Furthermore, the keyboard is provided with a first conductive terminal exposed to the outside and connected to the first circuit board, and the host is provided with a second conductive terminal located on the side wall and exposed to the outside. When the host is leaning against the cover, the first conductive terminal and the second conductive terminal are docked to realize signal connection between the host and the keyboard.

[0010] Furthermore, the portable ultrasonic diagnostic device also includes a first magnetic component provided on the host and a second magnetic component provided on the keyboard component. When the first magnetic component and the second magnetic component are adsorbed together, the first conductive terminal and the second conductive terminal are docked.

[0011] Furthermore, the first magnetic component is arranged on the bottom wall of the host, and the second magnetic component is arranged on the cover.

[0012] Furthermore, the portable ultrasonic diagnostic equipment also includes a support member arranged behind the cover plate for supporting the cover plate, the support member and the cover plate are rotatably connected, and the opening angle of the cover plate is adjusted by rotating the support member.

[0013] Furthermore, the bottom wall is provided with an inserting interface, the cover plate is provided with a through hole, and the portable ultrasonic diagnostic equipment further comprises a connector that connects with the inserting interface through the through hole to realize signal connection between the probe and the host.

[0014] Furthermore, the plug-in port is recessed, and when the host leans against the cover, the host and the cover fit together.

[0033] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0034] See also Figures 1 to 6 As shown, the present application provides a portable ultrasonic diagnostic device 100, which includes a host 1, a probe assembly 3 connected to the host 1, and a keyboard assembly 2. Preferably, the host 1 is a tablet with a touch screen. Since the host 1 is relatively light, it is relatively easy to carry. When in use, the probe assembly 3 is connected to the host 1, and the probe 31 of the probe assembly 3 scans the subject to obtain an ultrasonic image of the subject. Preferably, the probe assembly 3 and the host 1 are wired. The probe assembly 3 includes a probe 31, a connector 32, and a wire 33 connecting the probe 31 and the connector 32. The wire 33 is flexible, so the probe 31 can move freely within a certain range relative to the host 1. As needed, the probe 31 can be a linear array, a convex array, a phased array, etc., without any specific restrictions. Generally, a host 1 needs to be configured with multiple types of ultrasonic probes 31.

[0035] The host 1 includes a housing, a first circuit board 14 disposed in the housing, and a display screen 11 fixed to the housing. The housing includes side walls 12 and a bottom wall 13 disposed opposite the display screen 11. The bottom wall 13 is provided with a probe plug-in port 131, which is electrically connected to the first circuit board 14. A plurality of electronic components (not shown) are disposed on the first circuit board 14 to control the display of the host 1. Preferably, a battery 15 (see FIG. 1 ) is disposed in the host 1. Figure 9), the battery 15 can power the first circuit board 14. The battery 15 can be a rechargeable battery. When the battery 15 is exhausted or nearly exhausted, it can be recharged without replacing the battery 15. During use, the connector 32 is connected to the plug interface 131, and the signals collected by the probe 31 are processed to generate an ultrasound image, which is displayed on the display screen 11.

[0036] The plug interface 131 is provided with a fixing portion 132 having a fixing hole 1321. The connector 32 is provided with a rotatable fixing member 321. The end 3211 of the fixing member 321 is placed in the fixing hole 132, and the fixing member 321 is rotated to secure the connector 32 within the plug interface 131. When the connector 32 is secured within the plug interface 131, the terminals on the connector 32 mate with the terminals within the plug interface 131, establishing a signal connection between the probe 31 and the first circuit board 14. Although in this embodiment, the connector 32 is secured within the plug interface 131 via the fixing member 321, in other embodiments, the connector 32 may be secured within the plug interface 131 via other means, such as magnetic attraction.

[0037] The plug interface 131 is recessed inward from the bottom wall 13 of the host 1, and this setting allows the bottom wall 13 of the host 1 to be flat. When the host 1 is placed on a desktop or other flat surface, the host 1 can fit well with the desktop and will not tilt due to imbalance. In the prior art, on a flat host 1, the plug interface 131 is set on the side wall of the host 1. Since the connector 32 of the ultrasound probe 31 needs to transmit more signals, the volume of the connector 32 is relatively large. If the plug interface 131 is placed on the side wall, the thickness of the host 1 will be thicker, thereby increasing the overall weight of the host 1. Since the area of ​​the bottom wall 13 of the host 1 is relatively large, the present application sets the plug interface 131 on the bottom wall 13 of the host 1, and the bottom wall 13 allows the plug interface 131 to have a larger design space. The plug interface 131 can be set large enough to meet the signal connection between the ultrasound probe 31 and the first circuit board 14. At the same time, since no plug-in interface is required on the side of the host 1, the thickness of the host 1 can be set very small, and the thickness of the host is less than or equal to 25 mm.

[0038] The keyboard assembly 2 includes a keyboard 21, a cover plate 22 rotatably connected to the keyboard 21, and a support member 23 for supporting the cover plate 22. When the host 1 is placed on the cover plate 22, the keyboard 21 is connected to the host 1 for signal communication, and the keyboard 21 can control the host 1. Preferably, the cover plate 22 and the keyboard 21 are connected by an elastic member 25 (see FIG. Figure 7When not in use, the cover 22 can be folded together with the keyboard 21, and the support member 23 can be folded together with the cover 22. This folding process minimizes the space occupied by the keyboard assembly 2, making it easier to carry. When in use, the cover 22 is opened, the support member 23 is rotated to fix the cover 22 at the desired angle, and the main unit 1 is placed on the cover 22. If the angle of the main unit 1 needs to be adjusted, it is only necessary to adjust the angle of the support member 23. By placing the main unit 1 on the cover 22, the user only needs to hold the ultrasound probe 31 during use, rather than holding the main unit 1, thereby reducing the difficulty of operation for the user.

[0039] The cover 22 has a through hole 221. When the host 1 rests on the cover 22, the connector 32 can pass through the through hole 221 and dock with the socket 131. When the host 1 rests on the cover 22, the sidewalls of the host 1 abut against the keyboard 21. In this embodiment, when the connector 32 is secured in the socket 131, the host 1 is secured to the cover 22.

[0040] See Figure 7 and Figure 8 As shown, the keyboard 21 is provided with a first conductive terminal 211 exposed to the outside and connected to the first circuit board 14, and the host 1 is provided with a second conductive terminal 16 located on the side wall and exposed to the outside. When the host 1 is placed on the cover 22, the first conductive terminal 211 is docked with the second conductive terminal 16 to realize the signal connection between the host 1 and the keyboard 21.

[0041] To facilitate docking of the first conductive terminal 211 and the second conductive terminal 16, the portable ultrasonic diagnostic device 100 further includes a first magnetic component 17 disposed on the main unit 1 and a second magnetic component 222 disposed on the keyboard assembly 21. When the first magnetic component 17 and the second magnetic component 222 are attracted together, the first conductive terminal 211 and the second conductive terminal 16 are docked. Preferably, the first magnetic component 17 is disposed on the bottom wall 13 of the main unit 1, and the second magnetic component 222 is disposed on the cover 22. The arrangement of the first magnetic component 17 and the second magnetic component 222 allows the main unit 1 to be fixed to the cover 22 while aligning the first conductive terminal 211 and the second conductive terminal 16. When the main unit 1 is placed on the cover 22, the magnetic attraction of the first magnetic component 17 and the second magnetic component 222 secures the main unit 1 to the cover 22. At this point, the first conductive terminal 211 and the second conductive terminal 16 are attached together, and the insertion port 131 is aligned with the through hole 221. The connector 32 is fixed to the plug port 131 via the through hole 221 , thereby further strengthening the effect of fixing the host 1 to the cover 22 .

[0042] Although the host 1 and the cover 22 are fixed together by two magnetic components in this embodiment, in other embodiments, they can be fixed together by other means, such as by snap-fitting. In addition, in addition to achieving signal connection through the docking of conductive terminals, the host 1 and the keyboard 21 can also achieve signal connection through Bluetooth, which is not limited to this.

[0043] The host 1 is equipped with a battery 15. When the probe 31 is connected to the host 1, the battery 15 powers the host 1 and the probe 31, eliminating the need for a separate battery in the probe 31. If the host 1 and keyboard 21 are connected via conductive terminals, the keyboard 21 does not need a battery. The battery 15 in the host 1 can power the keyboard 21. If the host 1 and keyboard 21 are connected via Bluetooth, a separate battery is required in the keyboard 21.

[0044] When the host 1 is not placed on the cover 22, the ultrasonic diagnostic device 100 can be operated and controlled by touching the display screen 11. When the host 1 is placed on the cover 22, the host 1 is connected to the keyboard 21, and the ultrasonic diagnostic device 100 can be operated and controlled by touching the display screen 11 or clicking the keys on the keyboard 21. This configuration allows for flexible selection of the ultrasonic diagnostic device 100 based on user needs. For example, in locations where space is limited or where the keyboard assembly 2 is unsuitable, the user will need to hold the host 1. In locations where the keyboard assembly 2 can be placed, placing the host 1 on the keyboard assembly 2 can reduce operator difficulty.

[0045] exist Figure 7 In the embodiment, the cover plate 22 is opened at a certain angle. If the angle of the cover plate 22 needs to be further increased, such as Figure 8 As shown, it is only necessary to open the angle of the support member 23 to a larger angle, and then the angle of the cover plate 22 can be adjusted to a larger angle.

[0046] When the host 1 is placed on the cover 22 , the side walls of the host 1 abut against the keyboard 21 , thereby preventing the host 1 from sliding downward relative to the cover 22 .

[0047] See also Figure 9 As shown, the probe 31 is provided with a second circuit board 312 and a transducer 311 signal-connected to the second circuit board 312. The probe 31 is signal-connected to the host 1. The host 1 includes a first circuit board 14 disposed within the housing and signal-connected to the second circuit board 312. The first circuit board 14 is provided with an FPGA module 141, a receiving module 142, and a transmitting module 143. The receiving module 142 and the transmitting module 143 are used to control the reception and transmission of signals by the transducer 311. The signals received by the transducer 311 are processed to generate an ultrasound image, which is displayed on the display screen 11.

[0048] In the prior art, the FPGA module 141, receiving module 142, and transmitting module 143 are located within the ultrasound probe 31. These three modules are prone to heating during use. If the ultrasound probe 31 is used for extended periods, the housing of the ultrasound probe 31 can become hot, causing discomfort to the user. By placing the FPGA module 141, receiving module 142, and transmitting module 143 within the housing of the main unit 1, since these heat-prone components are no longer located within the ultrasound probe 31, the ultrasound probe 31 no longer becomes hot, preventing user discomfort.

[0049] Since a host needs to be configured with multiple different types of ultrasound probes, the FPGA module 141, the receiving module 142 and the transmitting module 143 are arranged in the shell of the host 1. Therefore, the FPGA module 141, the receiving module 142 and the transmitting module 143 do not need to be set in the multiple ultrasound probes purchased, thereby reducing the cost of the ultrasound diagnostic equipment 100.

[0050] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
