[0002] The palm ultrasonic diagnostic instrument is a portable medical device that can be used for ultrasonic examination and diagnosis. It is usually composed of a handheld probe and a display screen. Users can use the probe to scan the body surface and then observe the ultrasonic image on the display screen. The palm ultrasonic diagnostic instrument has the advantages of portability, easy to carry and use, and is therefore very useful in some special situations, such as emergency, operating room, ICU, etc. In addition, it can also be used in some situations where it is not convenient to perform conventional ultrasonic examination.

[0003] The ultrasonic probe is the core component of the palm ultrasonic diagnostic instrument, responsible for transmitting and receiving ultrasonic waves, converting the sound wave signals of the examination area into electrical signals, and then transmitting them to the host for processing.

[0068] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0069] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, in the drawings, the thickness of the components can be exaggerated or reduced for effective description of the technical content.

[0070] In this embodiment, the product 100 pressed by the pressing tool 010 is a palm ultrasonic diagnostic instrument, i.e. a smart wireless palm color Doppler ultrasound, which is a special design for electronic sealant filling treatment in the cavity of the smart wireless palm color Doppler ultrasound. Other devices or instruments do not have the need for ultrasonic probe filling treatment, so the pressing tool 010 cannot be used.

[0071] Please refer to Figure 1 and Figure 2 , in which, in order to facilitate understanding and illustration, Figure 2 the line of the joint position 120 is thickened in

[0072] In this embodiment, the shell 110 of the palm ultrasonic diagnostic instrument includes an upper shell 111, a lower shell 112 and at least one probe shell 113; the upper shell 111 and the lower shell 112 are cooperatively arranged and buckled by a buckle structure, and the at least one probe shell 113 is mounted on the end of the upper shell 111 and the lower shell 112 by a detachable structure; that is, the part of the probe shell 113 connected with the upper shell 111 and the lower shell 112 is the joint position 120. Since the shell has a rectangular structure and has a certain arc characteristic; the joint position 120 includes a planar joint 121 and a side joint 122, the planar joint 121 is located on the upper surface of the shell, and the side joint 122 is located on the two side edges of the shell.

[0073] In an optional embodiment, the palm-sized ultrasonic diagnostic apparatus can include one probe housing 113, and the probe housing 113 is mounted on the left end or the right end of the upper housing 111 and the lower housing 112 by a detachable structure.

[0074] Of course, the ultrasonic device can also include two probe housings 113, and the two probe housings 113 are respectively mounted on the left end and the right end of the upper housing 111 and the lower housing 112, that is, the ultrasonic probe is spliced by at least two parts at the position corresponding to the joint, and a joint position 120 is left on the outer surface of the shell 110. The shell 110 composed of the upper housing 111, the lower housing 112 and at least one probe housing 113 forms an installation cavity inside.

[0075] It can be understood that, in order to ensure the high-temperature resistance, low-temperature resistance and waterproof properties of the product 100, the part connecting the probe housing 113 with the upper housing 111 and the lower housing 112 needs to be treated by glue pouring. For the daily temperature change, for the palm-sized ultrasonic diagnostic apparatus, due to the small space of the glue pouring, the glue 130 will expand in volume at the corresponding temperature, and thus it is difficult to control the specific amount of the glue 130. If the amount of the glue 130 is insufficient, the glue pouring will not be sufficient. Therefore, in order to ensure the sealing effect, the amount of the glue 130 is usually slightly excessive, and then part of the glue 130 is overflowed by the pressing of the pressing tool 010, and the overflowed glue 130 on the surface of the product 100 is cleaned by the cleaning process. Since the shell 110 of the ultrasonic device has a certain arc and is not regular and flat, the glue 130 will overflow at the planar joint 121 on the upper surface of the shell 110, and the glue 130 will flow under the action of gravity and slope. At the same time, since the sealant will shrink after solidification, if the glue 130 flows away at the planar joint 121 on the upper surface of the shell 110, the glue pouring will be insufficient at the glue pouring position after the glue 130 solidifies.

[0076] Therefore, the palm-sized ultrasonic diagnostic apparatus pressed in this way not only has the problem of glue overflow, but also needs to be cleaned by the cleaning process after the overflow of the glue 130 on the surface of the product 100, which makes the process complicated and low in efficiency.

[0077] At least one embodiment provides a pressing tool 010 for pressing the palm-sized ultrasonic diagnostic apparatus, so that the palm-sized ultrasonic diagnostic apparatus can be stably combined, the shell and the sealant of the palm-sized ultrasonic diagnostic apparatus can be perfectly combined, the problems of glue overflow and expansion are solved, and the problem of insufficient amount of glue 130 on the top surface of the palm-sized ultrasonic diagnostic apparatus caused by the volume shrinkage of the glue 130 after solidification is avoided.

[0078] Please refer to Figure 3The press-fit tool 010 provided in the embodiment comprises a body 200 and a sealing structure 300. The body 200 is provided with a press-fit station 201 for placing a product 100. The product 100 is provided with a joint position 120. The sealing structure 300 is arranged on the body 200. The sealing structure 300 is provided with a sealing cavity 301. The sealing cavity 301 is arranged opposite to the press-fit station 201 so that the product 100 is located in the sealing cavity 301. The sealing structure 300 is provided with an inner cavity. The inner cavity is arranged opposite to and close to the joint position 120. The sealing structure 300 is used to adjust the pressure state of the sealing cavity 301 and the inner cavity.

[0079] It can be understood that the product 100 is placed on the press-fit station 201. At this time, the sealing cavity 301 is in a positive pressure state. The pressure state of the sealing cavity 301 and the inner cavity is adjusted to a negative pressure state by the sealing structure 300. The glue 130 at the joint position 120 has strong fluidity, which promotes the bubbles in the glue 130 to be discharged. At the same time, the glue 130 overflowing at the joint position 120 flows into the inner cavity under the negative pressure state, avoiding the good fluidity of the glue 130 flowing out along the joint position 120, avoiding the problem that the amount of glue 130 on the upper surface of the product 100 is insufficient due to the volume reduction after the glue 130 solidifies, maintaining the amount of glue 130 at the joint position 120 of the product 100, and ensuring the overall shaping effect of the product 100.

Alternatively, the positioning rods 316 are positioning screws with threads.

[0097] It is worth mentioning that the setting height of the first protrusion 312 in the embodiment should be close to the position of the planar joint 121 on the upper surface of the product 100 so that the glue 130 can be sucked into the first inner cavity 3121 under negative pressure; or the first inner cavity 3121 can directly abut against the position of the planar joint 121 on the upper surface of the product 100, please refer to Figure 10 .

[0098] In the embodiment, please refer to Figure 7The sealing plate 320 is a rectangular plate, and is arranged in the sealing cavity 301 and attached to the inner wall of the sealing cavity 301 of the sealing box 310. The sealing plate 320 is arranged opposite to the arc-shaped first opening 323 of the first protrusion 312 and the arc-shaped third opening 324 of the third protrusion 314. The first opening 323 is arranged opposite to the first protrusion 312 and cooperates with the first protrusion 312, that is, the first protrusion 312 can move up and down along the first opening 323.

[0099] Based on the above structure, the pressing process of the pressing tool 010 also needs to consider that the joint position 120 corresponds to the position of the glue filling area, otherwise it is not suitable for the pressing tool 010 and the corresponding pressing method.

[0100] The top of the sealing plate 320 is provided with a lifting piece 325, and the top of the sealing box 310 is provided with a second opening 315. The lifting piece 325 extends out of the sealing cavity 301 along the second opening 315, and the lifting piece 325 is lifted to make the sealing plate 320 slide up and down along the sealing cavity 301.

[0101] In this embodiment, please refer to Figures 5-7 The sealing plate 320 is provided with an inner core 321, and the inner core 321 is connected with the sealing plate 320 through a connecting block 3211. The connecting block 3211 moves up and down along the matching groove 3122 arranged on the side wall of the first protrusion 312. The inner core 321 is located in the first opening 323 and is arranged in the first inner cavity 3121 in a matching sliding manner.

[0102] The connecting block 3211 moves up and down along the matching groove 3122 to drive the inner core 321 to move up and down along the first inner cavity 3121, so that the first inner cavity 3121 and the second inner cavity 3131 are in a negative pressure state.

[0103] After the negative pressure state ends, the connecting block 3211 moves downward along the matching groove 3122 to drive the inner core 321 to move downward along the first inner cavity 3121, so that the first inner cavity 3121 and the second inner cavity 3131 are in a positive pressure state.

[0104] It can be understood that, please refer to Figure 8 , Figure 9 and Figure 10 , the product 100 after glue filling is placed on the positioning station, and the sealing plate 320 is controlled to move upward by the lifting piece 325. Because the product 100 occupies a large space in the sealing cavity 301, the sealing cavity 301 is in a slightly negative pressure state, which enhances the flowability of the glue 130 of the joint position 120 and also promotes the discharge of bubbles in the glue 130. After the negative pressure state ends, the sealing plate 320 is controlled to move downward by the lifting piece 325, so that the sealing cavity 301 is in a positive pressure state, which can make the glue 130 of the joint position 120 quickly solidify.

[0105] Further, please refer to Figure 5 , both sides of the first protrusion 312 extend the second protrusion 313, the inner side wall of the second protrusion 313 is provided with a second groove, the second groove forms a second inner cavity 3131, the second groove is communicated with the first groove; both sides of the inner core 321 extend the slide bar 3212, the slide bar 3212 is matched with the first groove and is slidably arranged, so that the slide bar 3212 moves up and down along the side seam 122.

[0106] It can be understood that, please refer to Figure 11 , the first inner cavity 3121 of the first protrusion 312 is arranged relative to the position of the plane seam 121 on the upper surface of the product 100; because the sealing plate 320 drives the inner core 321 to move together, the inner core 321 slides upward along the first inner cavity 3121, so that the first inner cavity 3121 is in a negative pressure state with the pressure state at the plane seam 121, thereby accelerating the overflow of the glue 130 at the plane seam 121; because the first protrusion 312 abuts at the plane seam 121 on the upper surface of the product 100, the glue 130 at the plane seam 121 flows into the first inner cavity 3121 after overflowing under the negative pressure state, avoiding the glue 130 at the plane seam 121 flowing to the two side walls of the shell 110 due to gravity and the curvature of the product 100.

[0107] Further, the second inner cavity 3131 of the second protrusion 313 is arranged relative to the position of the side seam 122 on the two sides of the product 100; because the inner core 321 slides upward along the first inner cavity 3121, the inner core 321 drives the slide bars 3212 on both sides to slide upward along the second inner cavity 3131 of the second protrusion 313, so that the second inner cavity 3131 is in a negative pressure state with the pressure state at the side seam 122, thereby accelerating the overflow of the glue 130 at the side seam 122. Because the first protrusion 312 abuts at the side seam 122 on the two sides of the product 100, the glue 130 at the side seam 122 flows into the second inner cavity 3131 after overflowing under the negative pressure state, avoiding the overflow of the glue 130 at the side seam 122.

[0108] Further, after the negative pressure state ends, the sealing plate 320 and the inner core 321 are controlled to move downward along the first inner cavity 3121 by the lifting piece 325, so that the sealing cavity 301 is in a positive pressure state, so that the glue 130 at the plane seam 121 and the side seam 122 can be quickly solidified.

[0109] It is worth mentioning that, please refer to Figure 12So that the sealing cavity 301, the first cavity and the second cavity maintain a micro-negative pressure state for a period of time, the sealing plate 320 is lowered so that the bottom wall of the sealing plate 320 is completely pressed on the upper surface of the product 100. At this time, the sealing plate 320 drives the inner core 321 and the slide bar 3212 to move downward together, and the slide bar 3212 moves downward along the second inner cavity 3131 to push the glue 130 in the second inner cavity 3131 downward along the second inner cavity 3131; because the sealing cavity 301 is in a micro-positive pressure state at this time, the glue 130 at the joint position 120 quickly solidifies, and the slide bar 3212 pushes out the excess glue 130 overflowing at the side joint 122 of the side wall surface of the product 100, which can avoid too much glue 130 adhering to the side wall of the product 100.

[0110] Among them, the time for the sealing cavity 301, the first cavity and the second cavity to maintain a micro-negative pressure state is controlled according to the actual product 100 requirements, and the time can be 10-30min, that is, 10min, 15min, 20min, 25min and 30min, etc.

[0111] In this embodiment, considering the practicability and reliability of the pressing tool 010, the pressing tool 010 needs to meet the intelligent demand.

[0112] In this embodiment, considering that the pressing tool 010 may cause damage to the palm color ultrasound shell material when in use, protection must be done on the contact surface where the pressing tool 010 contacts the shell 110, and cotton cloth is used to pad to make the pressing device more practical and avoid scratching and bruising the product 100.
