Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an ultrasonic probe. Background Art

[0002] Ultrasound probes are medical instruments that use ultrasound to examine tissue. To improve ease of use and portability, some handheld ultrasound probes currently utilize wireless communication, often referred to as wireless ultrasound probes. Wireless ultrasound probes are battery-powered, and charging the battery requires a probe charging mechanism. Common probe charging mechanisms include USB ports and Type-C connectors.

[0003] Wireless ultrasound probes require cleaning and disinfection after use. Traditionally, this is done with alcohol wipes. However, when waterproofing is required, the entire probe body needs to be fully immersed in a disinfectant.

[0045] Example 1

[0046] like Figure 1Figure 2 shows an ultrasound probe, which can be a handheld wireless ultrasound probe with a charging function. The ultrasound probe includes a housing, a charging connector 4, a mainboard 5, a battery (not shown), and an acoustic head assembly 6. The housing, which serves as the entire housing or a portion of the entire housing, has an internal mounting cavity. The housing comprises an upper housing 1 and a lower housing 2, which are interconnected and enclose the mounting cavity. The charging connector 4, mainboard 5, and battery are all located within the mounting cavity. The housing is a modular shell with one end open and the other closed. The acoustic head assembly 6 is mounted on the open end of the housing and is used to transmit and receive ultrasonic signals. The charging connector 4 can be used for both charging and signal transmission. It is mounted on the end of the mainboard 5 away from the acoustic head assembly 6 and embedded in the closed ends of the upper and lower housings 1 and 2. The closed ends of the housings are provided with an interface mounting slot 3 for mounting the charging connector 4 and communicating with the outside world.

[0047] like Figure 3 As shown in FIG. 8 , a boss 120 is formed on the end surface where the upper and lower shells 1 and 2 meet, projecting toward the lower shell 2. The boss 120 extends along the contour of the end surface where the upper and lower shells 1 and 2 meet. An inwardly recessed groove 220 is formed on the end surface where the lower and upper shells 2 meet, extending along the contour of the end surface where the lower and upper shells 2 meet. The boss 120 and groove 220 are mating, extending in the same direction. The thickness of the boss 120 is equal to the width of the groove 220, and the height of the boss 120 is slightly less than the depth of the groove 220. The groove 220 is suitable for accommodating adhesive. During the assembly of the upper shell 1 and the lower shell 2 , the boss 120 of the upper shell 1 is embedded in the groove 220 of the lower shell 2 and the adhesive is squeezed to achieve adhesive fixation of the upper shell 1 and the lower shell 2 .

[0048] In this embodiment, an upper recess 110 is formed on the end surface where the upper shell 1 and the lower shell 2 connect. The upper recess 110 divides the boss 120 into two sections. A lower raised portion 210 is also formed on the end surface where the lower shell 2 connects to the upper shell 1. The lower raised portion 210 divides the groove 220 into two sections. The upper recess 110 is provided with an upper interface groove 111, and the lower raised portion 210 is provided with a lower interface groove 211. The ends of the upper interface groove 111 and the lower interface groove 211 are butted together to form an interface mounting groove 3. The shape of the interface mounting groove 3 matches the shape of the charging connector 4, and the charging connector 4 partially extends into the interface mounting groove 3.

[0049] In this embodiment, the lower raised portion 210 has a lower stopper surface 213 that blocks the outward-facing side of the charging connector 4 and serves as the sidewall of the lower interface slot 211. The upper recessed portion 110 has an upper stopper surface 113 that blocks the outward-facing side of the charging connector 4 and serves as the sidewall of the lower interface slot 211. The lower stopper surface 213 and the upper stopper surface 113 cooperate to form a retaining structure that prevents the charging connector 4 from being removed from the housing. During assembly, the charging connector 4 is inserted into the housing along with the motherboard 5 from the open end until the outward-facing side of the charging connector 4 abuts against the stopper structure.

[0050] In some embodiments, the wall thickness of the portion of the upper housing 1 with the upper recess 110 is greater than the wall thickness of the portion of the upper housing 1 with the boss 120, and the wall thickness of the portion of the lower housing 2 with the upper protrusion is greater than the wall thickness of the portion of the lower housing 2 with the groove 220. This allows the interface mounting slot 3 to have a greater depth, and the charging connector 4 to be inserted into the housing wall for a longer distance. The bottom of the upper interface slot 111 is provided with an inwardly recessed upper glue storage groove 112, and the bottom of the lower interface slot 211 is provided with an inwardly recessed lower glue storage groove 212. The upper and lower glue storage grooves 112 and 212 are butted together at both ends to form a circumferentially closed glue storage groove, which is connected to the interface mounting slot 3. The gap between the inner wall of the glue reservoir and the outer surface of the charging connector 4 is filled with a first waterproof sealing layer (not shown) formed by cured adhesive. This first waterproof sealing layer seals the gap between the outer surface of the charging connector 4 and the glue reservoir, preventing external moisture from entering the interior of the housing through the joint between the charging connector 4 and the housing, thereby improving the waterproof rating of the ultrasound probe. When the adhesive in groove 220 is subjected to a compressive force, the adhesive will preferentially overflow into the glue reservoir. Once the glue reservoir is fully filled, the adhesive in the glue reservoir will overflow into the interface mounting groove 3. This allows the gaps within the glue reservoir and the interface mounting groove 3 to be sealed by the cured adhesive, which helps improve the waterproof rating. This glue reservoir configuration is also simple in structure and easy to manufacture.

[0051] In some embodiments, the adhesive in the glue storage tank will overflow into the interface mounting groove 3. After the adhesive overflowing from the glue storage tank fills the interface mounting groove 3 and solidifies, a second waterproof sealing layer (not shown) is formed in the gap between the inner wall of the interface mounting groove 3 and the outer surface of the charging connector 4. The second waterproof sealing layer can prevent external moisture from entering the shell through the joint gap between the charging connector 4 and the shell, further improving the waterproof level of the ultrasound probe. It should be noted that the first waterproof sealing layer and the second waterproof sealing layer are actually an integrated cured adhesive, and are named accordingly only according to the difference in position after the adhesive is cured.

[0052] In some embodiments, the lower adhesive reservoir 212 is located directly in the center of the lower interface groove 211, and its width is one-third of the width of the lower interface groove 211. When the lower adhesive reservoir 212 is filled with adhesive, it overflows into the lower interface grooves 211 on both sides. The upper adhesive reservoir 112 is located directly in the center of the upper interface groove 111, and its width is one-third of the width of the upper interface groove 111. When the upper adhesive reservoir 112 is filled with adhesive, it overflows into the upper interface grooves 111 on both sides. In the radial direction of the interface mounting groove 3, due to its greater depth, the waterproof sealing layer formed after curing of the adhesive is also thicker, and the path for external moisture to penetrate into the interior of the shell is also longer, which is beneficial for improving the waterproof effect.

[0053] In some embodiments, the lower raised portion 210 includes a pair of lower boss structures 240 that separate the groove 220 and the lower interface groove 211. The lower interface groove 211 and the lower glue storage tank 212 are located between the pair of lower boss structures 240. The upper shell 1 is provided with a pair of upper step structures 140 that match the pair of lower boss structures 240. The upper interface groove 111 and the upper glue storage tank 112 are located between the pair of upper step structures 140. After the upper shell 1 and the lower shell 2 are assembled together, a gap is formed between the lower boss structure 240 and the upper step structure 140. This gap serves as an overflow channel 230 connecting the groove 220 and the glue storage tank, allowing adhesive to overflow from the groove 220 into the glue storage tank.

[0054] Before the upper shell body 1 and the lower shell body 2 are assembled, adhesive is placed in the groove 220 of the lower shell body 2. When the upper shell body 1 and the lower shell body 2 are assembled, the boss 120 of the upper shell body 1 extends into the groove 220 of the lower shell body 2. The adhesive in the groove 220 is squeezed and overflows outward. Since the overflow channel 230 formed on the docking surface of the lower shell body 2 and the upper shell body 1 connects the groove 220 and the glue storage tank, the adhesive in the groove 220 will overflow into the glue storage tank through the overflow channel 230 after being squeezed, and then overflow from the glue storage tank to the interface mounting groove 3. After the adhesive is cured in the glue storage tank, a first waterproof sealing layer is formed. After the adhesive is cured in the interface mounting groove 3, a second waterproof sealing layer is formed, thereby improving the waterproof level of the ultrasonic probe. Since the amount of adhesive stored in the glue storage tank is limited and it is not easy to directly and completely fill the interface mounting groove 3 with the adhesive in a flowing state, the adhesive flows to the interface mounting groove 3 through the groove 220, the overflow channel 230, and the glue storage tank during the assembly process. Since the adhesive is subjected to extrusion force before curing, the adhesive can more fully fill the gap between the interface mounting groove 3 and the charging connector 4 before curing, thereby ensuring the sealing reliability of the first waterproof sealing layer and the second waterproof sealing layer formed after the subsequent adhesive is cured.

[0055] In the first assembly method of the shell body and the charging connector 4, before the shell body is assembled, the adhesive is first applied to the inner wall of the interface mounting groove 3, and then the charging connector 4 is directly inserted into the interface mounting groove 3, and the adhesive is cured to form a waterproof sealing layer; because the adhesive is fluid before curing and the interface mounting groove 3 is an open groove, on the one hand, it is difficult for the adhesive to completely fill the interface mounting groove 3, and on the other hand, the adhesive in the upper interface groove 111 of the upper shell body 1 is easy to flow downward, resulting in the waterproof sealing layer formed by the curing of the adhesive having poor density and thickness consistency, and the final waterproof performance is relatively general.

[0056] In the second assembly method of the shell body and the charging connector, an inwardly recessed glue storage tank is additionally provided in the interface mounting groove 3. During assembly, the adhesive overflowing from the glue storage tank is used to fill the interface mounting groove 3 to form a first waterproof sealing layer on the periphery of the charging connector 4. Compared with the first assembly method, although the problem of the adhesive being difficult to retain in the interface mounting groove 3 is reduced to a certain extent, the space of the glue storage tank is limited. Only a small amount of adhesive in the glue storage tank can overflow into the interface mounting groove 3. Only the adhesive in the glue storage tank can form a first waterproof sealing layer of a certain thickness after curing. A dense second waterproof sealing layer cannot be formed in the interface mounting groove 3, and the final waterproof performance is still relatively general.

[0057] Compared with the two assembly methods of the shell body and the charging connector 4 mentioned above, the assembly method of the shell body and the charging connector 4 provided in this embodiment has a larger space in the groove 220, which can accommodate more adhesive, and more adhesive is required to be set in the groove 220 of the lower shell body 2 to achieve the adhesive sealing connection between the lower shell body 2 and the upper shell body 1. This embodiment utilizes the adhesive in the groove 220 to overflow into the glue storage tank through the overflow channel 230 after being squeezed, and the adhesive then flows from the glue storage tank to the interface mounting groove 3. Since the adhesive is subjected to the extrusion force before solidification, the adhesive can more fully fill the glue storage tank and the interface mounting groove 3 before solidification, forming a relatively thick and thick waterproof sealing layer between the interface mounting groove 3 and the charging connector 4, thereby greatly improving the waterproof performance of the joint between the shell body and the charging connector 4, which can reach the waterproof level of medical equipment. In addition, since the adhesive used to seal the upper shell body 1 and the lower shell body 2 in the groove 220 generally has a surplus, a small amount of adhesive may overflow from the joint gap between the upper shell body 1 and the lower shell body 2 toward the outer wall of the shell body during the traditional assembly of the upper shell body 1 and the lower shell body 2. In this embodiment, since the opening size of the overflow channel 230 is larger than the size of the joint gap between the upper shell body 1 and the lower shell body 2, the excess adhesive in the groove 220 will preferentially overflow through the overflow channel 230 during assembly, thereby reducing the phenomenon of adhesive overflowing from the joint gap between the upper shell body 1 and the lower shell body 2 toward the outer wall of the shell body.

[0058] In some embodiments, the lower housing 2 includes a lower inner retaining wall 221 forming the inner sidewall of the groove 220 and a lower outer retaining wall 222 forming the outer sidewall of the recess. The lower raised portion 210 includes a pair of lower boss structures 240 separating the groove 220 and the lower interface groove 211. The lower interface groove 211 and the lower glue storage groove 212 are located between the pair of lower boss structures 240. The upper housing 1 is provided with a pair of upper step structures 140 that mate with the pair of lower boss structures 240. The upper interface groove 111 and the upper glue storage groove 112 are located between the pair of upper step structures 140.

[0059] Specifically, the lower boss structure 240 includes an integrally formed lower boss inner stopper 241, a lower boss outer stopper 242, and a lower boss intermediate stopper 243. The lower boss intermediate stopper 243 is located between the lower boss inner stopper 241 and the lower boss outer stopper 242. The lower boss inner stopper 241 serves as a partition between the lower inner retaining wall 221 and the lower interface groove 211, the lower boss outer stopper 242 serves as a partition between the lower outer retaining wall 222 and the lower interface groove 211, and the lower boss intermediate stopper 243 serves as a partition between the groove 220 and the lower glue storage tank 212. The upper step structure 140 includes an integrally formed upper inner step 141, an upper outer step 142, and an upper intermediate step 143. The upper intermediate step 143 is located between the upper inner step 141 and the upper outer step 142. The two stepped surfaces of the upper inner step 141 have a concavo-convex fit with the two adjacent end surfaces of the lower boss inner stop 241. The two stepped surfaces of the upper outer step 142 have a concavo-convex fit with the two adjacent end surfaces of the lower boss outer stop 242. The two stepped surfaces of the upper middle step 143 have a concavo-convex fit with the two adjacent end surfaces of the lower boss middle stop 243. The gap between the lower boss middle stop 243 and the upper middle step 143 forms the overflow channel 230.

[0060] In some embodiments, the raised height of the lower boss middle stopper 243 is lower than the raised heights of the lower boss inner stopper 241 and the lower boss outer stopper 242, that is, the upper end surface of the lower boss middle stopper 243 is lower than the upper end surfaces of the lower boss inner stopper 241 and the lower boss outer stopper 242. The two step surfaces of the upper middle step 143 protrude toward the lower boss middle stopper 243 relative to the two step surfaces of the upper inner step 141 and the upper outer step 142. A gap is provided between the lower boss middle stopper 243 and the upper middle step 143, forming an overflow channel 230 connecting the groove 220 and the adhesive storage tank. The adhesive in the groove 220 can overflow into the adhesive storage tank through the overflow channel 230, and then overflow from the adhesive storage tank into the interface mounting groove 3 to form a second waterproof sealing layer.

[0061] In some embodiments, the lower boss intermediate stopper 243 has an upper overflow surface 243a facing the upper shell body 1 and a side overflow surface 243b facing away from the lower interface groove 211. The upper intermediate step 143 has an upper step surface 143a disposed opposite the upper overflow surface 243a and a side step surface 143b disposed opposite the side overflow surface 243b. The sides of the lower boss inner stopper 241 and the lower boss outer stopper 242 facing away from the lower interface groove 211 serve as the lower boss outer end surface. The side overflow surface 243b of the lower boss intermediate stopper 243 is recessed inwardly by a certain depth relative to the lower boss outer end surface, i.e., the lower boss inner stopper 241 and the lower boss outer stopper 242 have side inner end surfaces 241a. The side step surface 143b of the upper intermediate step 143 extends between the pair of side inner end surfaces 241a and is disposed opposite the side overflow surface 243b. The side step surface 143b, the side overflow surface 243b, and the pair of side inner end surfaces 241a together form a vertical overflow channel for the adhesive in the groove 220 to flow upward. The upper step surface 143a and the upper overflow surface 243a, between the lower boss inner stopper 241 and the lower boss outer stopper 242, form a transverse overflow channel for the adhesive to flow toward the adhesive reservoir. During assembly of the upper and lower housings 1 and 2, the adhesive in the groove 220, under pressure, flows along the vertical and transverse overflow channels toward the adhesive reservoir, and then from there toward the interface mounting slot 3. This overflow channel 230, consisting of both vertical and transverse overflow channels, prevents adhesive from overflowing from the gaps between the lower boss inner stopper 241 and the upper inner step 141, and between the lower boss outer stopper 242 and the upper outer step 142, allowing more adhesive to overflow from the groove 220 toward the adhesive reservoir.

[0062] In this ultrasonic probe, during the assembly process of the upper shell body 1 and the lower shell body 2, the adhesive in the glue storage tank will overflow into the interface mounting groove 3. After the adhesive is cured in the gap between the inner wall of the glue storage tank and the outer surface of the charging connector 4, a first waterproof sealing layer is formed. After the adhesive is cured in the gap between the inner wall of the interface mounting groove 3 and the outer surface of the charging connector 4, a second waterproof sealing layer is formed. This can prevent external moisture from entering the interior of the shell body through the joint gap between the charging connector 4 and the shell body, thereby greatly improving the waterproof level of the ultrasonic probe.

[0063] Example 2

[0064] like Figure 9The ultrasonic probe shown in FIG13 differs from the first embodiment primarily in the locations of the glue storage tank and overflow channel 230. An upper interface groove structure 150 is provided on the upper housing 1, and a lower interface groove structure 250 is provided on the lower housing 2. The upper interface groove structure 150 is provided with a pair of upper blocks 151 that serve as a separator between the groove 220 and the upper interface groove 111, while the lower interface groove structure 250 is provided with a pair of lower blocks 251 that serve as a separator between the boss 120 and the lower interface groove 211. The upper interface groove 111 is formed between the pair of upper blocks 151, and the lower interface groove 211 is formed between the pair of lower blocks 251. The upper interface groove 111 and the lower interface groove 211 are joined to form an interface mounting groove 3. The shape of the interface mounting groove 3 matches that of the charging connector 4, and the charging connector 4 partially extends into the interface mounting groove 3. The interior of the lower shell body 2 is also provided with a lower partition structure. The lower partition structure, the lower inner retaining wall 221, and the lower interface groove structure 250 enclose the interior of the lower shell body 2 to form a lower glue storage tank 212. The interior of the upper shell body 1 is provided with an upper partition structure. The upper partition structure and the upper interface groove structure 150 enclose the upper glue storage tank 112 on the upper shell body 1. The lower glue storage tank 212 and the lower glue storage tank 212 enclose a glue storage tank, and the portion of the charging connector 4 exposed outside the interface mounting groove 3 is located in the glue storage tank. The difference between Example 2 and Example 1 is that in Example 2, the glue storage tank is located in the mounting cavity of the shell body rather than in the wall of the shell body.

[0065] When the upper shell 1 and the lower shell 2 of this ultrasonic probe are assembled, since the portion of the charging connector 4 exposed outside the interface mounting groove 3 is located in the glue storage groove, the adhesive in the glue storage groove will form a first waterproof sealing layer on the outer periphery of the charging connector 4 after curing, and the adhesive in the glue storage groove will overflow into the interface mounting groove 3. The adhesive will form a second waterproof sealing layer after curing in the gap between the inner wall of the interface mounting groove 3 and the outer surface of the charging connector 4, which is beneficial to increase the sealing thickness of the entire waterproof sealing layer and improve the waterproof level of the ultrasonic probe.

[0066] In some embodiments, in order to save the amount of adhesive in the glue storage tank, fillers are provided inside the upper glue storage tank 112 and the lower glue storage tank 212, and the adhesive is provided above the fillers. When the upper shell body 1 and the lower shell body 2 are assembled, the adhesive between the fillers is cured on the periphery of the charging connector 4 to form a first waterproof sealing layer.

[0067] In some embodiments, the lower baffle structure includes a lower first baffle 261 disposed opposite the lower interface trough structure 250, a pair of lower second baffles 262 connected between the lower first baffle 261 and the lower inner retaining wall 221 and disposed oppositely thereto, and a lower third baffle 263 connected between the lower first baffle 261 and the lower interface trough structure 250 and separating the lower glue storage trough 212. The upper baffle structure includes an upper first baffle 161 disposed opposite the upper interface trough structure 150, a pair of upper second baffles 162 integrally connected between the upper first baffle 161 and the upper interface trough structure 150 and disposed oppositely thereto, and an upper third baffle 163 integrally connected between the upper first baffle 161 and the upper interface trough structure 150 and separating the upper glue storage trough 112. A notch is defined in the lower inner retaining wall 221, connecting the groove 220 and the glue storage trough. The upper second baffle 162 extends into the notch, and the gap between the notch and the upper second baffle 162 serves as an overflow channel 230. Such a configuration facilitates the adhesive in the groove 220 of the lower shell body 2 to overflow into the glue storage tank through the overflow channel 230, thereby squeezing the adhesive in the glue storage tank. After being squeezed, the adhesive in the glue storage tank is more likely to fill the interface mounting groove 3, forming a waterproof barrier with high density and thicker waterproof sealing layer thickness, thereby improving the waterproof level of the ultrasonic probe.

[0068] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
