Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to an extender and an ultrasonic imaging device. Background Art

[0002] An ultrasonic imaging device uses an ultrasonic beam to scan the human body, and obtains an image of an internal organ by receiving and processing reflected signals, which is an important auxiliary device for a doctor to diagnose a patient's condition.

[0003] Existing ultrasonic imaging devices generally include a probe, a main unit, and a display. The probe and the display are both electrically connected to the main unit. The probe is used to scan the human body, and the image is transmitted to the display through the main unit. The ultrasonic imaging device is also provided with a probe extender. There are two sockets on the extender. One socket is arranged on the side surface of the extender, and the other socket is arranged on the top surface of the extender. The side surface and the top surface are connected and perpendicular to each other. The socket on the side surface of the extender is used to plug into the main unit, and the socket on the top surface of the extender is used to plug into the probe. The plugging direction of the probe is perpendicular to the plugging direction of the main unit.

[0004] However, the defect of this extender is that: setting a socket on the top surface of the extender requires the extender to have sufficient width in the horizontal direction so that the socket can be arranged on the top surface of the extender, which makes the width of the extender larger, and then the volume of the extender is larger, resulting in a larger occupied space for the whole device. In addition, generally, the extender is first plugged into the main unit, and the installation part of the extender is fixedly connected to the main unit by screws. Then, the probe is plugged into the socket on the top surface of the extender. However, since the plugging direction of the probe is perpendicular to the plugging direction of the main unit, when the probe is plugged into the socket on the top surface of the extender, the position where the socket on the side surface of the extender is plugged into the main unit will be subjected to the force of plugging and unplugging the probe. The force of plugging and unplugging the probe is perpendicular to the extending direction of the socket on the side surface of the extender. With the long-term plugging and unplugging operation of the probe, the socket on the side surface of the extender will be deformed or even damaged, making the plugging between the extender and the main unit insecure, resulting in loose connection or even connection failure between the extender and the main unit. Summary of the Utility Model

[0005] In view of this, the utility model provides an extender and an ultrasonic imaging device to solve the problems that the existing probe extender has a large volume and the socket is easily deformed or even damaged.

[0006] To achieve the above object, the following technical solutions are provided:

[0007] An extender for connecting a main unit and a probe, the extender includes:

[0008] A housing having a first housing jack and a second housing jack, the first housing jack and the second housing jack are respectively arranged on a group of opposite side surfaces of the housing;

[0009] The movement assembly is arranged inside the housing. The movement assembly includes a shielding cover and a circuit board. The circuit board is arranged inside the shielding cover. The shielding cover is provided with a first shielding cover jack and a second shielding cover jack. The first shielding cover jack corresponds to the first housing jack, and the second shielding cover jack corresponds to the second housing jack. The probe is inserted into the circuit board through the first housing jack and the first shielding cover jack. The circuit board is also inserted into the host through the second shielding cover jack and the second housing jack.

[0010] By arranging the circuit board inside the shielding cover and then arranging the circuit board and the shielding cover as a whole inside the housing of the expander, the shielding cover effectively shields the electromagnetic interference during the insertion and connection of the probe and the host to the circuit board. In addition, the housing is provided with a first housing jack and a second housing jack. The first jack and the second housing jack are respectively arranged on a set of opposite sides of the housing, that is, the extending directions of the first jack and the second housing jack are parallel. The shielding cover is provided with a first shielding cover jack corresponding to the first housing jack for the probe to be inserted into the circuit board, and the shielding cover is provided with a second shielding cover jack corresponding to the second housing jack for the host to be inserted into the circuit board. Therefore, the insertion and extraction directions of the probe and the host are parallel. Therefore, the width of the expander along the insertion and extraction direction of the probe is set to be smaller, thereby reducing the volume of the expander. Since the insertion and extraction directions of the probe and the host are parallel, the risk of deformation or even damage to the first housing jack, the second housing jack, the first shielding cover jack or the second shielding cover jack of the expander is avoided, ensuring the reliability of the connection between the expander and the host and the probe.

[0011] Optionally, there are at least two first housing jacks, and the at least two first housing jacks are arranged in parallel in the vertical direction. This enables the expander to be inserted with at least two probes simultaneously, while ensuring that the width of the expander is small and the structure is compact.

[0012] Optionally, the circuit board includes a board body, a male socket and a female socket. The male socket and the female socket are both arranged on the board body and electrically connected to the board body. The socket of the male socket is placed inside the first shielding cover jack, and the socket of the female socket is placed inside the second shielding cover jack. This realizes the effective electromagnetic shielding of the shielding cover at the insertion and connection positions of the probe and the host to the circuit board.

[0013] Optionally, the male socket is arranged on the second side of the board body, and the female socket is arranged on the first side of the board body, so that the insertion and extraction directions of the male socket and the female socket are parallel. This ensures that the expander is not easily damaged during long-term insertion and extraction, and the probe and the host have a relatively large insertion and extraction space relative to the expander.

[0014] Optionally, the shielding cover includes a first shielding cover and a second shielding cover that are detachably connected. The first shielding cover jack is arranged on the first shielding cover, and the second shielding cover jack is arranged on the second shielding cover. This arrangement of the shielding cover makes the installation of the shielding cover and the circuit board more convenient.

[0015] Optionally, a shielding frame is provided around the female socket. On the basis that the shielding cover plays an electromagnetic shielding role for the circuit board, the shielding frame further plays an electromagnetic shielding role for the female socket and strengthens the firmness of the female socket, making the female socket not easily damaged.

[0016] Optionally, the shielding frame includes two shielding brackets arranged oppositely. Each shielding bracket includes a bottom plate and two side plates. The two side plates are respectively connected to opposite sides of the bottom plate, and an installation portion is provided on the bottom plate. The installation portion is connected to the plate body. This setting of the shielding frame facilitates the installation and cooperation of the shielding frame and the female socket.

[0017] Optionally, elastic pieces are provided between the upper and lower sides of the female socket and the shielding frame. The elastic pieces are connected to the upper and lower sides of the female socket and are grounded. This ensures the conductive safety of the female socket.

[0018] Optionally, an installation plate is provided on one side of the second shielding cover. The installation plate extends towards the host and is connected to the host. This effectively improves the connection stability between the host and the expander, prevents the female socket from being damaged due to external force factors, and avoids the situation of loose connection between the female socket and the host.

[0019] An ultrasonic imaging device includes a host, a probe, a display, and an expander. The probe is plugged into the host through the expander, and the host is electrically connected to the display.

[0020] Since the ultrasonic imaging device of the present invention includes the expander of the present invention and has the same beneficial effects as the expander of the present invention, they will not be elaborated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] As Figure 1 and Figure 2 shown, the expander of this embodiment includes a housing 1 and a movement assembly 2. The housing 1 has a first housing jack 111 and a second housing jack 121, and the first housing jack 111 and the second housing jack 121 are respectively arranged on a set of opposite sides of the housing 1. The movement assembly 2 is arranged inside the housing 1. The movement assembly 2 includes a shielding cover 3 and a circuit board 4. The circuit board 4 is arranged inside the shielding cover 3. The shielding cover 3 is provided with a first shielding cover jack 311 and a second shielding cover jack 321. The first shielding cover jack 311 corresponds to the first housing jack 111, and the second shielding cover jack 321 corresponds to the second housing jack 121. The probe 6 is plugged into the circuit board 4 through the first housing jack 111 and the first shielding cover jack 311. The circuit board 4 is also plugged into the main unit 5 through the second shielding cover jack 321 and the second housing jack 121.

[0036] This kind of extender places the circuit board 4 inside the shielding cover 3, and then the circuit board 4 and the shielding cover 3 as a whole are placed inside the housing 1 of the extender. The shielding cover 3 plays an effective electromagnetic shielding role for the insertion and connection of the probe 6 and the host 5 on the circuit board 4. In addition, the housing 1 is provided with a first housing jack 111 and a second housing jack 121. The first housing jack 111 and the second housing jack 121 are respectively arranged on a set of opposite sides of the housing 1, that is, the extending directions of the first housing jack 111 and the second housing jack 121 are parallel. The shielding cover 3 is provided with a first shielding cover jack 311 corresponding to the first housing jack 111 for the probe 6 to be inserted and connected to the circuit board 4, and the shielding cover 3 is provided with a second shielding cover jack 321 corresponding to the second housing jack 121 for the host 5 to be inserted and connected to the circuit board 4. Therefore, the insertion and extraction directions of the probe 6 and the host 5 are parallel. Therefore, the width of the extender in the insertion and extraction direction of the probe 6 is set to be smaller, thereby reducing the volume of the extender. Since the insertion and extraction directions of the probe 6 and the host 5 are parallel, the risk of deformation or even damage of the first housing jack 111, the second housing jack 121, the first shielding cover jack 311 or the second shielding cover jack 321 of the extender is avoided, ensuring the reliability of the insertion and connection of the extender with the host 5 and the probe 6.

[0037] It should be noted that Figures 1 to 3 the direction of the axis where X is located in [] is the insertion and extraction direction of the extender, and the direction of the axis where Z is located is the vertical direction.

[0038] Furthermore, the housing 1 includes a front shell 11 and a rear shell 12 that are detachably installed. The first housing jack 111 is opened on the front shell 11, and the second housing jack 121 is opened on the rear shell 12. The movement component 2 is fixed in the rear shell 12 by screws to improve the reliability of the insertion and extraction operation of the movement component 2.

[0039] Specifically, the front shell 11 and the rear shell 12 are detachably installed by screws to improve the overall structural strength of the extender.

[0040] Furthermore, at least two first housing jacks 111 are provided, and at least two first housing jacks 111 are arranged in parallel in the vertical direction, thereby enabling the extender to insert and connect at least two probes 6 simultaneously.

[0041] In this embodiment, the first housing jacks 111 are arranged side by side in the vertical direction. This arrangement method of the first housing jacks 111 on the front shell 11 can ensure that more first housing jacks 111 can be provided on the front shell 11, and at the same time, it can ensure that the width of the extender is smaller, the structure is compact, and the occupied space is small.

[0042] In this embodiment, two first housing jacks 111 are provided, and two probes 6 can be inserted and connected simultaneously.

[0043] In other embodiments, according to the setting space, the first socket 111 of the housing may also be provided with three, five, etc.

[0044] Further, as Figure 2 and Figure 3 shown, the circuit board 4 includes a board body 41, a male socket 42 and a female socket 43. The male socket 42 and the female socket 43 are both arranged on the board body 41 and electrically connected to the board body 41. The socket of the male socket 42 is placed in the first socket 311 of the shielding cover and is used for plugging with the probe 6. The socket of the female socket 43 is placed in the second socket 321 of the shielding cover and is used for plugging with the host 5. Thus, the shielding cover 3 effectively shields the electromagnetic interference at the plugging positions of the probe 6 and the host 5 on the circuit board 4.

[0045] Further, the male socket 42 is arranged on the second side surface 412 of the board body 41, and the female socket 43 is arranged on the first side surface 411 of the board body 41, so that the plugging and unplugging directions of the male socket 42 and the female socket 43 are parallel, ensuring that the extender is not easily damaged during long-term plugging and unplugging, and the probe 6 and the host 5 have a relatively large plugging and unplugging space relative to the extender.

[0046] Further, the male socket 42 and the female socket 43 are welded to the board body 41 to ensure the reliability of the plugging and unplugging of the male socket 42 and the female socket 43.

[0047] Further, the shielding cover 3 includes a detachable first shielding cover 31 and a second shielding cover 32. The first socket 311 of the shielding cover is arranged on the first shielding cover 31, and the second socket 321 of the shielding cover is arranged on the second shielding cover 32, facilitating the installation of the shielding cover 3 and the circuit board 4.

[0048] Specifically, the board body 41 is connected to the second shielding cover 32 by screws to enhance the overall strength of the extender.

[0049] Further, on the basis that the shielding cover 3 shields the electromagnetic interference of the circuit board 4, a shielding frame is arranged around the female socket 43 to further shield the electromagnetic interference of the female socket 43 and enhance the firmness of the female socket 43, making the female socket 43 not easily damaged.

[0050] Further, for the convenience of the installation and cooperation of the shielding frame and the female socket 43, the shielding frame includes two relatively arranged shielding brackets 44. The shielding bracket 44 includes a bottom plate 441 and two side plates 442. The two side plates 442 are respectively connected to the opposite sides of the bottom plate 441, and an installation portion 443 is arranged on the bottom plate 441. The installation portion 443 is connected to the board body 41.

[0051] Specifically, the installation portion 443 is detachably connected to the board body 41 by screws, and both shielding brackets 44 are detachably connected to the female socket 43 by screws to enhance the overall structural strength of the extender and make the plugging and unplugging operation of the extender more reliable.

[0052] Further, elastic pieces 45 are arranged between the upper and lower sides of the female socket 43 and the shielding frame. The elastic pieces 45 are connected to the upper and lower sides of the female socket 43 and are grounded to ensure the conductive safety of the female socket 43.

[0053] Specifically, the elastic pieces 45 are fixedly installed on the upper and lower sides of the female socket 43 by screws.

[0054] Further, two connection seats 46 are arranged on the board body 41. Both of the two connection seats 46 are electrically connected to the female socket 43. One connection seat 46 is electrically connected to one male socket 42, and the other connection seat 46 is electrically connected to the other male socket 42. This ensures the reliability of the electrical connection between the male socket 42 and the female socket 43.

[0055] Further, as Figure 4 shown, an installation board 33 is arranged on one side of the second shielding cover 32. The installation board 33 extends towards the host 5 and is connected to the host 5. Through the connection between the installation board 33 and the host 5, the stability of the connection between the host 5 and the expander is effectively improved, preventing the female socket 43 from being damaged due to external force factors and avoiding the situation of loose connection between the female socket 43 and the host 5.

[0056] Specifically, the installation board 33 and the host 5 are connected by screws to achieve detachable installation between the expander and the host 5.

[0057] As Figure 4 and Figure 5 shown, this embodiment provides an ultrasonic imaging device. The ultrasonic imaging device includes a host 5, a probe 6, a display, and an expander. The probe 6 is plugged into the host 5 through the expander, and the host 5 is also electrically connected to the display.

[0058] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
