Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and particularly relates to an ultrasonic device and an ultrasonic probe. Background Art

[0002] An ultrasonic probe is a medical device that uses the mutual conversion between electrical signals and ultrasonic signals to perform ultrasonic examinations and diagnoses. The ultrasonic probe usually has buttons for turning the ultrasonic probe on and off or switching function modes.

[0003] Due to the requirements of the probe's usage scenarios, the probe needs to meet high-level waterproof requirements, which also limits the cooperation method between the buttons and the housing. Common cooperation methods for waterproof assembly of the housing and buttons include glue-sealing assembly schemes, secondary injection molding schemes, two-color injection molding schemes, etc.

[0004] Among them, the glue-sealing assembly scheme requires separately injection-molding the buttons and the housing first, and then combining and sealing them with glue. Therefore, there are pain points such as the sealant being easily spilled from the edge, being unable to be thoroughly cleaned, affecting the appearance, and the assembly process consuming time and cost. The secondary injection molding scheme is similar to the two-color injection molding scheme, and both require two injection moldings to achieve the purpose of forming the buttons and the housing successively and combining them. However, due to the increase in the number of injection moldings, and either manual placement of the buttons into the mold by workers or complex mold switching actions are required between the two injection moldings, resulting in higher production costs and poorer production convenience. In addition, in the above three assembly schemes, after the buttons are pressed for a long time, the combined edge of the buttons and the housing is prone to de-bonding and opening, resulting in the risk of dirt accumulation or water ingress.

[0042] The serial numbers assigned to the components in this article, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connections (couplings).

[0043] An ultrasonic device is a medical device that uses the mutual conversion between electrical signals and ultrasonic signals to perform ultrasonic examinations and diagnoses.

[0044] This embodiment provides an ultrasonic device.

[0045] Please refer to Figure 1-7 , the ultrasonic device can be a desktop ultrasonic device or a handheld ultrasonic imaging device.

[0046] For example, in one embodiment, the ultrasonic device is a desktop ultrasonic device, which includes an ultrasonic probe 1000 and an independent main unit. A processor is provided in the main unit, and the main unit is signal-connected to the ultrasonic probe 1000 in a wired or wireless manner.

[0047] Also, for example, in one embodiment, the ultrasonic device is a handheld ultrasonic imaging device, which includes an ultrasonic probe 1000, and the processor is integrated in the probe housing 100 of the ultrasonic probe 1000. Therefore, the probe housing 100 of the handheld ultrasonic imaging device has higher requirements for protection performance and key durability, and the production cost of the probe housing 100 directly affects the overall cost of the handheld ultrasonic imaging device.

[0048] On the other hand, this embodiment also provides an ultrasonic probe 1000.

[0049] The ultrasonic probe 1000 can be applied to the above-mentioned desktop ultrasonic device or handheld ultrasonic device, especially the above-mentioned handheld ultrasonic device.

[0050] Please refer to Figure 1-7 , the ultrasonic probe 1000 includes a probe housing 100, a sound head assembly 200, and a circuit board 300.

[0051] The sound head assembly is installed in the probe housing 100 and is used to emit ultrasonic waves to a target tissue and receive the echo signals of the ultrasonic waves. The circuit board 300 is installed in the probe housing 100, and the circuit board 300 includes at least one trigger element 310. The probe housing 100 includes an integrally formed film layer 110 and a substrate layer 120, and the film layer 110 and the substrate layer 120 are at least partially stacked. The film layer 110 forms at least one key structure 111, and at least one key structure 111 is correspondingly arranged with at least one trigger element 310. The substrate layer 120 includes a through structure 121. When a user presses at least one key structure 111, the film area where the at least one key structure 111 is located can pass through the through structure 121 to press the corresponding at least one trigger element 310, so that the corresponding at least one trigger element 310 generates a corresponding control signal.

[0052] Please refer to Figure 1-4When using the ultrasonic probe 1000, the user can press the button structure 111 formed by the film layer 110 so that the film area where the button structure 111 is located can pass through the travel structure 121, thereby pressing on the trigger element 310 corresponding to the button structure 111, and then the pressed trigger element 310 generates a corresponding control signal. Since the film layer 110 and the base layer 120 are integrally formed, on the one hand, the integral forming makes the film layer 110 and the base layer 120 have better bonding, so that the button structure 111 formed on the film layer 110 and the base layer 120 have better bonding, and then the button structure 111 is not easy to debond and crack when pressed, reducing the risk of dirt or water ingress into the button structure 111. On the other hand, since the film layer 110 can be formed by hot pressing and punching, the molding process is simpler and the cost is lower, and it does not rely on injection molding. Therefore, the film layer 110 and the base layer 120 can be integrally formed by one injection molding, which is less costly and more suitable for mass production than the conventional solution which requires two injection moldings.

[0053] In actual production, the film layer 110 and the base layer 120 can be integrally formed by film insert injection molding, that is, please refer to Figure 1-4 In one embodiment, the probe housing 100 includes a film layer 110 and a base layer 120 which are integrally formed by film-in-film injection molding.

[0054] In the production process of membrane insert injection molding, the film layer 110 can be first formed by hot pressing and punching, and then the film layer 110 is placed in an injection mold, and then the base layer 120 is injection molded in the mold, so that the base layer 120 and the film layer 110 form an integrally molded probe housing 100.

[0055] Please refer to Figure 1-5 In one embodiment, the film layer 110 is located on a side of the base layer 120 away from the circuit board 300 .

[0056] When the user presses the key structure 111 on the film layer 110, the direction of the force applied by the finger is from the side of the film layer 110 away from the base layer 120 toward the bonding side of the film layer 110 and the base layer 120. For details, please refer to Figure 3 In the direction shown by the pressing force F in FIG. 1 , the force of the finger in this case is not easy to drive the film layer 110 to separate from the base layer 120, but will make the film layer 110 and the base layer 120 more tightly combined. Therefore, when the film layer 110 is located on the side of the base layer 120 away from the circuit board 300, the user pressing the key structure 111 is not easy to cause the film layer 110 and the base layer 120 to separate or generate a gap, which is conducive to improving the durability of the probe housing 100.

[0057] Please refer toFigure 1-5 It should be noted that the thin film layer 110 may be a single film body layer 113, or may further include a printing layer 114 and / or an adhesive layer 115. The following embodiments will illustrate in detail the specific cases where the thin film layer 110 includes the film body layer 113 and the printing layer 114, the thin film layer 110 includes the film body layer 113 and the adhesive layer 115, and the film body layer 113 includes the film body layer 113, the printing layer 114 and the adhesive layer 115.

[0058] Please refer to Figure 1-5 , in one embodiment, the thin film layer 110 includes a film body layer 113 and a printing layer 114. The printing layer 114 is used to form a key identifier 117 of the key structure 111 on the film body layer 113. The key identifier 117 is used for users to identify the key structure 111. The printing layer 114 is located on the side of the film body layer 113 facing the base layer 120.

[0059] On the one hand, the printing layer 114 can form the key identifier 117 of the key structure 111 on the film body layer 113, so that users can identify the key structure 111 through the key identifier 117. And the key identifier 117 also enables users to more clearly see the position of the key structure 111, thus facilitating users to accurately press the key structure 111. On the other hand, the printing layer 114 is located on the side of the film body layer 113 facing the base layer 120, so that the printing layer 114 will not be directly contacted with the cleaning agent or disinfectant when the user cleans the probe housing 100, thereby avoiding the fading of the printing layer 114 due to the user's cleaning operation. Specifically, the printing layer 114 can be formed by means of ink printing.

[0060] Please refer to Figure 1-5 , in one embodiment, the thin film layer 110 includes a film body layer 113 and an adhesive layer 115. The adhesive layer 115 is located on the side of the film body layer 113 facing the base layer 120.

[0061] By providing the adhesive layer 115 between the thin film layer 110 and the base layer 120, the adhesion between the thin film layer 110 and the base layer 120 can be increased by the viscosity of the adhesive layer 115, which is further conducive to ensuring good adhesion between the thin film layer 110 and the base layer 120. Specifically, the adhesive layer 115 can be coated on the side of the thin film layer 110 for bonding with the base layer 120 before the base layer 120 is injection-molded.

[0062] Please refer to Figure 1-5, in one embodiment, the thin film layer 110 includes a film body layer 113, a printing layer 114, and an adhesive layer 115. The printing layer 114 is used to form a key identifier 117 of the key structure 111 on the film body layer 113. The key identifier 117 is used for the user to identify the key structure 111. The film body layer 113, the printing layer 114, and the adhesive layer 115 are arranged in sequence along the direction close to the substrate layer 120.

[0063] On the one hand, the printing layer 114 forms a key identifier 117 of the key structure 111 on the film body layer 113, so that the user can identify the key structure 111 through the key identifier 117, and the adhesive layer 115 is used to make the bonding force between the thin film layer 110 and the substrate layer 120 greater, thereby further facilitating the good bonding between the thin film layer 110 and the substrate layer 120. On the other hand, since the printing layer 114 is located between the film body layer 113 and the adhesive layer 115, it is beneficial to ensure that the printing layer 114 does not fade due to the user's cleaning operation. And the adhesive layer 115 is located on the side of the printing layer 114 facing the substrate layer 120, which is beneficial to achieve the purpose of increasing the bonding force between the thin film layer 110 and the substrate layer 120.

[0064] Please refer to Figure 1-5 , in one embodiment, the key identifier 117 includes at least one of text, graphics, and images.

[0065] It is convenient for the user to visually identify the key and confirm the position of the key through at least one of text, graphics, and images. Specifically, the key identifier 117 can be a single text, graphic, or image, or a combination of two or three of the above.

[0066] Please refer to Figure 1-4 , in one embodiment, the thin film area is also used to form a key portion 112, and at least one key structure 111 is provided on the key portion 112.

[0067] That is to say, the thin film area on the thin film layer 110 can form one or more key structures 111, and for the thin film area formed with one or more key structures 111, it can be regarded as the "key portion 112". When multiple key structures 111 are integrated on the key portion 112, it is convenient for the user to perform various different operations on the key portion 112. For example, the user can control the switch of the ultrasonic probe 1000 through one key structure 111 on the key portion 112, and control the function adjustment of the ultrasonic probe 1000 through another key structure 111 on the key portion 112.

[0068] Please refer to Figure 1-4 , in one embodiment, the key portion 112 is a convex structure or a concave structure, and at least two key structures 111 are arranged longitudinally or horizontally along the convex structure or the concave structure.

[0069] On the one hand, the button part 112 is set as a convex structure or a concave structure, making the button part 112 more prominent in visual effect, so as to facilitate the user to accurately find and press the button structure 111 on the button part 112. On the other hand, since at least two button structures 111 are integrated on the button part 112, it is convenient for the user to perform various different operations on the button part 112. For example, the user can control the switch of the ultrasonic probe 1000 through one button structure 111 on the button part 112, and control the function adjustment of the ultrasonic probe 1000 through another button structure 111 on the button part 112. Specifically, the above-mentioned "longitudinal direction" refers to the length direction of the probe housing 100, and the length direction can specifically refer to Figure 2 the direction shown by the central axis L1, and Figure 2 the direction shown by the central axis L2 is the thickness direction of the probe housing 100. The "transverse direction" refers to the width direction of the probe housing 100, which can specifically be regarded as perpendicular to Figure 2 the directions of the central axes L1 and L2.

[0070] Please refer to Figure 1-4 , in an embodiment, the shape of the button part 112 is quadrilateral, circular, oval or racetrack-shaped, and the shape of the through structure 121 is adapted to the shape of the button part 112.

[0071] On the one hand, the shape of the button part 112 can be flexibly selected according to the shape of the probe housing 100, the arrangement direction of the button structures 111 and other design requirements. On the other hand, the shape of the through structure 121 is adapted to the shape of the button part 112, so that all the button structures 111 on the button part 112 can pass through the through structure 121.

[0072] Please refer to Figure 1-4 , in an embodiment, the through structure 121 is a through opening.

[0073] When the user presses the button structure 111 formed by the film layer 110, the film area where the button structure 111 is located can pass through the through opening, so as to press the trigger element 310 corresponding to the button structure 111. In other embodiments, the through structure 121 can also be set as a through channel, as long as it can allow the button structure 111 to pass through.

[0074] Please refer to Figure 1-4 , in an embodiment, the button structure 111 includes a switch button structure 1111 and a function adjustment button structure 1112, and the switch button structure 1111 and / or the function adjustment button structure 1112 is provided with an identification mark 119, and the identification mark 119 is used to distinguish the switch button structure 1111 and the function adjustment button structure 1112.

[0075] On the one hand, the user can control the switch of the ultrasonic probe 1000 by pressing the switch button structure 1111, and can also switch the ultrasonic probe 1000 to different functional modes by using the function adjustment button structure 1112. On the other hand, due to the addition of the identification mark 119, it is not easy for the user to confuse the switch button structure 1111 and / or the function adjustment button structure 1112, thereby reducing the possibility that the user presses the wrong button structure 111.

[0076] Please refer to Figure 1-4 , in one embodiment, the identification mark 119 is a convex structure 1191 formed by the thin film layer 110 around the button structure 111.

[0077] The convex structure 1191 can not only help the user distinguish and identify the button structure 111 in terms of visual effect, but also bring a sense of distinction and feedback to the user in terms of the tactile effect of the finger when the user presses the button structure 111. In other embodiments, a raised or sunken dot matrix can also be used to replace the above-mentioned convex structure 1191.

[0078] Please refer to Figure 1-4 and 6, in one embodiment, the base layer 120 has a first side 122 and a second side 123 which are oppositely arranged, and the thin film layer 110 covers at least a part of the first side 122 of the base layer 120.

[0079] That is to say, according to the actual use requirements, the thin film layer 110 can completely or partially cover the first side 122 of the base layer 120. Specifically, when the thin film layer 110 completely covers the first side 122 of the base layer 120, more materials are used for the thin film layer 110, but it is beneficial to ensure the bonding effect between the thin film layer 110 and the base layer 120 and improve the durability of the button structure 111. When the thin film layer 110 partially covers the first side 122 of the base layer 120, less materials are used for the thin film layer 110.

[0080] Please refer to Figure 1-4 and 6, in one embodiment, the thin film layer 110 extends from the edge of the first side 122 to the second side 123 to form a wrapping edge structure 116.

[0081] By setting the wrapping edge structure 116, it is possible to prevent the step difference caused by the positioning deviation and the film flanging and warping caused by the demolding action, so that the bonding property between the thin film layer 110 and the base layer 120 is better, and the thin film layer 110 is flatter on the base layer 120.

[0082] Please refer to Figure 1-4 , in one embodiment, the ultrasonic probe 1000 further includes a force transmission member (not shown), the force transmission member is disposed between the button structure 111 and the trigger element 310, and the force transmission member is used to transmit the pressing force to the trigger element 310 when the button structure 111 is pressed.

[0083] When the pressing stroke between the key structure 111 and the triggering element 310 is long, the user's pressing experience may be reduced, and the deformation of the film area where the key structure 111 is located will be relatively large, resulting in the key structure 111 being more likely to be damaged. After adding a force transmission member between the key structure 111 and the triggering element 310, when the user presses the key structure 111, the pressing force can be transmitted to the triggering element 310 through the force transmission member, which is beneficial to shortening the pressing stroke when the user presses the key structure 111.

[0084] Please refer to Figure 1-4 , in one embodiment, the key structure 111 is located at the exact middle position of the probe housing 100.

[0085] When the user holds the probe housing 100 with one hand, the user can also press the key structure 111 located at the exact middle of the probe housing 100 with the fingers of the holding hand, thereby improving the convenience of user operation. Specifically, the "exact middle position of the probe housing 100" can be understood as being located at the middle position in both the length direction and the width direction of the probe housing 100.

[0086] Please refer to Figure 1-4 , in one embodiment, a first insulating paint layer 118 is provided on the side of the film area where the key structure 111 is located facing the triggering element 310, and a second insulating paint layer 311 is provided on the side of the triggering element 310 facing the key structure 111.
