Description

Technical Field

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

[0003] The ultrasonic probe is the core component of the handheld ultrasonic diagnostic instrument. It is responsible for transmitting and receiving ultrasonic waves, converting the sound wave signals in the inspection area into electrical signals, and then transmitting them to the host for processing. The shape and size of the probe will vary depending on the inspection area and purpose.

[0004] The inventors have found that during the manufacturing process of the ultrasonic probe, in order to ensure the high temperature resistance, low temperature resistance and waterproof properties of the product, it is necessary to fill the cavity of the ultrasonic probe with electronic sealant. In order to ensure the sealing effect, the specific amount of glue is usually difficult to control. If there is less glue, the glue filling will be incomplete. Therefore, in the actual operation process, the amount of glue used is often slightly more, and then some of the glue overflows due to the compression of the pressing tooling.

DETAILED DESCRIPTION

[0063] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0064] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0065] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0066] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or is the orientation or position relationship in which the inventive product 100 is usually placed when used. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0067] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0068] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0069] It should be noted that similar reference numerals 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 the subsequent drawings. In addition, in the drawings, the thickness of the components may be exaggerated or reduced in order to effectively describe the technical content.

[0070] In this embodiment, the product 100 pressed by the pressing tool 010 is a handheld ultrasonic diagnostic instrument, namely, an intelligent wireless handheld color ultrasound. It is a special design for filling the cavity of the intelligent wireless handheld color ultrasound with electronic sealant. Other equipment or instruments do not need to fill the ultrasound probe with sealant, so this pressing tool 010 cannot be used.

[0071] Please refer to Figure 1 and Figure 2 , where, for ease of understanding and illustration, Figure 2 The line at the seam position 120 is thickened.

[0072] In this embodiment, the housing 110 of the handheld ultrasonic diagnostic instrument includes an upper housing 111, a lower housing 112 and at least one probe housing 113; the upper housing 111 and the lower housing 112 are arranged in coordination and fastened by a snap-fit ​​structure, and at least one probe housing 113 is installed at the ends of the upper housing 111 and the lower housing 112 by a detachable structure; that is, the portion where the probe housing 113 is connected to the upper housing 111 and the lower housing 112 is a joint position 120. Since the housing is a rectangular structure with a certain curvature, the joint position 120 includes a plane joint 121 and a side joint 122, wherein the plane joint 121 is located on the upper surface of the housing, and the side joint 122 is located on both sides of the housing.

[0073] In an optional embodiment, the handheld ultrasonic diagnostic instrument may include a probe housing 113 , and the probe housing 113 is installed at the left end or the right end of the upper housing 111 and the lower housing 112 through a detachable structure.

[0074] Of course, the super ultrasound device can also include two probe shells 113, and the two probe shells 113 are respectively installed at the left end and the right end of the upper shell 111 and the lower shell 112, that is, the corresponding ultrasonic probe glue filling place is spliced ​​by at least two parts, and a seam position 120 is left on the outer surface of the shell 110. Among them, the shell 110 composed of the upper shell 111, the lower shell 112 and at least one probe shell 113 forms an installation cavity inside, and the installation cavity is used to install the electronic circuit structure.

[0075] It is understandable that in order to ensure the high temperature resistance, low temperature resistance and waterproof characteristics of the product 100, the part where the probe housing 113 is connected to the upper housing 111 and the lower housing 112 needs to be glued. For daily temperature changes, for small housing products 100 such as handheld ultrasonic diagnostic instruments, since the glue filling space is relatively small, the glue 130 will expand in volume at the corresponding temperature, making it difficult to control the specific amount of glue 130. If the glue 130 is insufficient, the glue filling will be incomplete. Therefore, in order to ensure the sealing effect, the glue 130 is usually slightly over-added, and then part of the glue 130 is overflowed by pressing the pressing tool 010, and then the glue 130 overflowing on the surface of the product 100 is cleaned through the cleaning process. Since the shell 110 of the super ultrasonic device has a certain curvature and is not regular and flat, the glue 130 will overflow from the plane seam 121 on its upper surface, and the glue 130 will flow under the action of gravity and the slope; at the same time, since the sealant will shrink to a certain extent after solidification, if the glue 130 at the plane seam 121 on the upper surface of the shell 110 flows away, the part that needs to be filled with glue will have insufficient glue after the glue 130 solidifies.

[0076] Therefore, the handheld ultrasonic diagnostic instrument pressed together in this way not only has the problem of glue overflow, but also needs to be cleaned through a cleaning process to clean the glue 130 overflowing on the surface of the product 100, which makes the process complicated and inefficient.

[0077] At least one embodiment provides a pressing tool 010 for pressing a handheld ultrasonic diagnostic instrument, so that the handheld ultrasonic diagnostic instrument can be stably assembled, and the shell and sealant of the handheld ultrasonic diagnostic instrument can be perfectly matched, so as to solve the problems of glue overflow and expansion, and avoid the problem of insufficient glue 130 on the top surface of the handheld ultrasonic diagnostic instrument due to the reduction of volume after the glue 130 solidifies.

[0078] Please refer to Figure 3The present embodiment proposes a pressing tool 010, which includes a body 200 and a sealing structure 300. The body 200 is provided with a pressing station 201 for placing the product 100, and the product 100 is provided with a joint position 120; the sealing structure 300 is provided on the body 200, and a sealing cavity 301 is provided in the sealing structure 300.

The sealing structure 300 is provided with an inner cavity, which is arranged relative 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 when the product 100 is placed on the pressing station 201, 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 through the sealing structure 300, so that the glue 130 at the seam position 120 has strong fluidity, which promotes the discharge of bubbles in the glue 130; at the same time, the glue 130 overflowing from the seam position 120 flows into the inner cavity under a negative pressure state, avoiding the glue 130 with good fluidity flowing out along the seam position 120, avoiding the problem of insufficient glue 130 on the upper surface of the product 100 due to the volume reduction of the glue 130 after solidification, maintaining the amount of glue 130 at the seam position 120 of the product 100, and ensuring the overall shaping effect of the product 100.

[0102] The connecting block 3211 moves up and down along the matching groove 3122 , driving 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, driving 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] Understandably, please refer to Figure 8 , Fig. 9 and Fig.10 , the glue-filled product 100 is placed on the positioning station, and the sealing plate 320 is controlled to move upward by the lifting member 325. Since 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 fluidity of the glue 130 at the joint position 120 and 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 member 325, so that the sealing cavity 301 is in a positive pressure state, which can make the glue 130 at the joint position 120 solidify quickly.

[0105] For further information, please refer to Figure 5 Second protrusions 313 extend from both sides of the first protrusion 312, and a second groove is provided on the inner wall of the second protrusion 313, and the second groove forms a second inner cavity 3131, and the second groove is connected to the first groove; sliding strips 3212 extend from both sides of the inner core 321, and the sliding strips 3212 are arranged in cooperation with the first groove and slidably arranged so that the sliding strips 3212 move up and down along the side seam 122.

[0106] Understandably, please refer to Fig.11 The first inner cavity 3121 of the first protrusion 312 is arranged relative to 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 pressure state between the first inner cavity 3121 and the plane seam 121 is in a negative pressure state, thereby accelerating the overflow of the glue 130 at the plane seam 121; because the first protrusion 312 abuts against the plane seam 121 on the upper surface of the product 100, the glue 130 at the plane seam 121 overflows under the negative pressure state and then flows into the first inner cavity 3121, thereby preventing the glue 130 at the plane seam 121 from flowing to the two side walls of the outer shell 110 due to gravity and the curvature of the outer shell 110 of the product 100.

[0107] Furthermore, the second inner cavity 3131 of the second protrusion 313 is arranged relative to the side seams 122 on both sides of the product 100; as 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 pressure state between the second inner cavity 3131 and the side seams 122 is in a negative pressure state, thereby accelerating the overflow of the glue 130 at the side seams 122. As the first protrusion 312 abuts against the side seams 122 on both sides of the product 100, the glue 130 at the side seams 122 overflows under the negative pressure state and then flows into the second inner cavity 3131, thereby preventing the glue 130 at the side seams 122 from overflowing.

[0108] Furthermore, 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 member 325, so that a positive pressure state is presented in the sealing cavity 301, so that the glue 130 at the plane seam 121 and the side seam 122 can solidify quickly.

[0109] It is worth mentioning that please refer to Fig.12, so that the sealing cavity 301, the first cavity and the second cavity maintain a slight negative pressure state for a period of time, and the sealing plate 320 is moved downward so that the bottom wall of the sealing plate 320 is completely pressed against 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 slight positive pressure state at this time, the glue 130 at the joint position 120 solidifies quickly, and the slide bar 3212 pushes out the excess glue 130 overflowing from the side joints 122 on the two side walls of the product 100, which can prevent excessive glue 130 from adhering to the side walls of the product 100.

[0110] Among them, the time for keeping the sealed cavity 301, the first cavity and the second cavity in a slightly negative pressure state is controlled according to the needs of the actual product 100, and the time can vary from 10 to 30 minutes, that is, it can be 10 minutes, 15 minutes, 20 minutes, 25 minutes and 30 minutes, etc.

[0111] In this embodiment, considering the practicality and reliability of the pressing tool 010, the pressing tool 010 needs to meet the intelligent requirements. Because the intelligent features of the pressing tool 010 are: by setting a pressure sensor in the sealed cavity 301 of the pressing tool 010, the pressure sensor and other software and hardware are controlled and coordinated to achieve automatic pressure calibration of the pressing tool 010 to complete the specific pressing of the specific product 100.

[0112] In this embodiment, considering that the pressing tool 010 may cause damage to the shell material of the handheld color ultrasound when in use, the contact surface between the pressing tool 010 and the shell 110 must be protected. The use of cotton cloth padding makes the pressing device more practical and avoids scratching or crushing the product 100.

The inner core 321 drives the sliding strips 3212 on both sides to move downward along the second inner cavity 3131 respectively, and pushes out the glue 130 in the second cavity and at the side seam 122.

[0123] In an optional embodiment, this embodiment also proposes a method for preparing a handheld ultrasound diagnostic instrument, which includes a shell, the shell is spliced ​​by at least two parts at the glue filling position of the ultrasound probe, and a seam position 120 is left on the outer surface of the shell.
