Components of an ultrasonic semi-dry water bag

Abstract

The present invention relates to the technical field of ultrasonic treatment equipment, and specifically to a component of an ultrasonic semi-dry water bag, wherein the bottom surface of the adhesive seat is an adhesive surface and is used to adhere to the surface of human skin, the bottom of the bag body is fixedly connected to the middle of the adhesive seat, and the cross-section between the bag wall of the bag body and the adhesive seat is an inverted "T"-shaped structure. In the present invention, the bag wall and the adhesive portion are connected in an "inverted T" shape, and the pressure F in the water bag is only 1-2 mm through the lever of point A to point O, so the amplification effect of its torque can be ignored. The torque effect of the pressure F in the water bag on the bag wall is transferred to point O', and the tearing force at point O' is evenly distributed on the inner and outer adhesive surfaces of point O' through the extension of the bag wall. In addition, due to the flexibility of the adhesive portion, the above-mentioned tearing force will be buffered and reduced, and further evenly distributed to the skin adhesive surface, thereby maintaining the firmness of the adhesive and preventing water leakage.

Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic treatment equipment, in particular to an ultrasonic semi-dry water bag component. Background Art

[0002] Common coupling methods used in ultrasound therapy include wet coupling and dry coupling. Dry coupling involves creating a water reservoir using an acoustically transparent material such as latex. The ultrasound emitting surface is inserted into the reservoir, which is then bonded to the skin to create an ultrasound channel. This method offers the advantages of being watertight, simple, lightweight, and time-saving.

[0003] Publication (Announcement) No.: CN217015102U discloses a coupling liquid sealing assembly for focused ultrasound and a focused ultrasound treatment system, comprising a pouch body with openings at both ends and a waterproof adhesive ring; the first connecting surface of the waterproof adhesive ring is used to be adhered to the patient's skin; the second connecting surface of the waterproof adhesive ring is bonded to the first end of the pouch body, and the second end of the pouch body is tightly connected to the housing of an ultrasound transmitting device; compared with a wet coupling liquid sealing device, it occupies less space, has a wider range of applications, requires much less auxiliary equipment, and consumes much less coupling liquid; compared with a dry coupling liquid sealing device, it eliminates the attenuation and absorption of ultrasound by the sealing membrane, thereby minimizing the skin damage caused thereby. At the same time, due to the direct heat absorption effect of the coupling liquid, the safety is greatly improved for patients undergoing long-term treatment.

[0004] The above-mentioned ultrasonic semi-dry water bag assembly greatly improves the safety of patients undergoing long-term treatment. However, the pressure inside the water bag of the ultrasonic semi-dry water bag assembly acts on the bag wall. Figure 6 As shown, due to the lever principle, a huge torque is generated at the bonding boundary point O between the adhesive part and the skin, resulting in the adhesive force f being unable to counteract the torque formed by F. The adhesive part and the skin cannot be permanently bonded. Especially when the treatment head moves, it will pull on the capsule wall, aggravating the tearing, causing detachment and leakage. Summary of the Invention

[0005] The object of the present invention is to provide an ultrasonic semi-dry water bag assembly to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An ultrasonic semi-dry water bag assembly is characterized by comprising a bag body (10) and an adhesive seat (30), wherein the bag body (10) is annular and hollow, the bottom surface of the adhesive seat (30) is an adhesive surface for adhering to the surface of human skin, and the bottom of the bag body (10) is connected to the middle of the adhesive seat (30).

[0008] This arrangement connects the bottom of the bag body (10) to the middle of the adhesive seat (30), which effectively avoids the problem of uneven force in the prior art. This connection method can reduce the torque in all directions of the connection part when the bag body (10) is deformed, making the force more uniform.

[0009] Preferably, the bottom edge of the pouch body (10) is in an inverted T-shape, and its bottom plane is fixedly connected to the upper surface of the adhesive seat (30).

[0010] This arrangement adopts a surface-to-surface connection, and the force bearing portion of the pouch body (10) is also arranged in the middle, forming an inverted T-shape, and the extension portion of the bottom edge of the pouch body (10) is used to jointly bear the tearing force. Since the main material of the pouch body (10) also has the ability to deform, the strength of the connection portion will be relatively high when excessively torn, and the deformation of the connection portion will reduce the torque, effectively preventing it from being torn off.

[0011] Preferably, a connecting seat is provided in the middle of the upper surface of the bonding seat (30), and the connecting seat is fixedly connected to the bottom edge of the bag body (10).

[0012] Preferably, the connecting seat is an annular protruding connecting seat.

[0013] These two configurations are provided with a special connecting seat, which forms an annular protective ring, can effectively withstand the impact of instantaneous tearing force, can effectively reduce the torque of the connecting part, and well protect the bag body (10).

[0014] Preferably, the bottom of the outer wall of the bag body (10) is provided with an annular thickened portion (12).

[0015] Preferably, the thickened portion (12) is arranged on the inner wall of the bladder body (10) or on the outer wall of the bladder body (10).

[0016] These two settings further improve the tear resistance of the connection part by strengthening and thickening the connection part.

[0017] Preferably, a fixed outer sleeve (20) is further included, wherein the fixed outer sleeve (20) is fixed on the adhesive seat (30) and covers the bag body (10) therein.

[0018] This configuration provides a fixed outer cover (20) that covers the outside of the bladder body (10) to prevent the bladder body (10) from excessive deformation and further protect the bladder body (10).

[0019] Preferably, the upper surface of the bonding seat (30) is provided with a mounting groove (31) adapted to the bottom of the fixed jacket (20), and the fixed jacket (20) is fixedly connected to the mounting groove (31).

[0020] Preferably, the top of the pouch body (10) is provided with a folding portion (13) for folding, and a through hole for installing the ultrasonic treatment head (11) is opened at the center of the top, and an elastic band (14) is embedded in the edge of the through hole.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In the components of this ultrasonic semi-dry water bladder, the bladder wall and the adhesive seat are connected in an "inverted T" shape. The connection point O' is located in the middle area of the adhesive seat (not necessarily the center point). The thickness of the adhesive portion is 1-2mm and the width is 30-40mm. The above values can be changed as needed. The pressure F in the bladder body is only 1-2mm through the lever of point A to point O, so its torque amplification effect can be ignored.

[0023] The torque effect of the pressure F inside the pouch body 10 on the pouch wall is transferred to point O', and the tearing force at point O' is evenly distributed to the inner and outer adhesive surfaces of point O' through the extended portion of the pouch wall.

[0024] Combined with the flexibility of the adhesive portion, the above-mentioned tearing force will be buffered and reduced, and further evenly distributed to the adhesive surface of the skin, thereby maintaining the firmness of the adhesive and preventing water leakage. Through calculation, the torque of the pressure F on the bladder wall, transmitted to point O through O', is only 1 / 10-1 / 15 of the original, thus greatly improving the anti-tear performance; in addition, above point O', the thickened part of the outer wall of the bladder surrounds the water bladder in a circular shape to prevent the base of the bladder wall from over-expanding and being pulled on O' when the contents of the bladder increase or the pressure increases; this further buffers and offsets part of the torque of F, which can better prevent tearing.

[0025] In the components of this ultrasonic semi-dry water bag, a folding portion is provided on the top of the bag body for folding, and a through hole for installing the ultrasonic treatment head is opened at the center of the top. An elastic band is embedded in the edge of the through hole to facilitate opening or closing the top of the bag body.

[0026] In the assembly of the ultrasonic semi-dry water bag, the top surface of the adhesive seat is provided with a mounting groove that matches the size of the mounting seat and is snap-fitted. The mounting seat is fixed in the mounting groove by fixing screws, which is convenient for installation or removal. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention and the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be understood that the terms "center", "vertical", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0040] A component of an ultrasonic semi-dry water bag, such as Figure 1-Figure 3As shown, it includes: a pouch body 10, which is hollow in an annular shape, with an open bottom and filled with water or coupling liquid, an ultrasonic treatment head 11 is installed on the top of the pouch body 10, and a ring-shaped thickened portion 12 is installed on the bottom of the outer wall of the pouch body 10; a fixed jacket 20, which is mounted on the outside of the pouch body 10, and a gap is left between the fixed jacket 20 and the outer wall of the pouch body 10; an adhesive seat 30, the bottom surface of the adhesive seat 30 is an adhesive surface, and is used to adhere to the surface of human skin, the adhesive seat 30 is annular, and is an integrally formed structure with the pouch body 10, the bottom edge of the pouch body 10 is an inverted T-shape, and a release film is provided at the bottom of the adhesive seat 30.

[0041] The force principle between the bag body 10 and the adhesive seat 30 is as follows: Figure 5 As shown, the force analysis is as follows:

[0042] The pouch body 10's wall and adhesive base 30 are connected in an inverted T-shape, with the connection point O' located in the middle of the adhesive base 30 (not necessarily the exact center). The adhesive portion has a thickness of 1-2 mm and a width of 30-40 mm, which can be adjusted as needed. The leverage of the pressure F within the pouch body 10 at point A on point O is only 1-2 mm, so its torque amplification effect is essentially negligible. The torque exerted by the pressure F within the pouch body 10 on the pouch wall is transferred to point O'. The tearing force at point O' is evenly distributed across the adhesive surface inside and outside point O' via the extended portion of the pouch wall. Combined with the adhesive's flexibility, this tearing force is buffered and reduced, further evenly distributing it across the skin surface where it is applied, thereby maintaining a secure bond and preventing leaks. Calculations show that the torque exerted by the pressure F on the bladder wall, transmitted through point O' to point O, is only 1 / 10-1 / 15 of its original value, significantly enhancing the tear-resistant performance. Furthermore, above point O', a thickened portion 12 on the outside of the bladder wall forms a ring around the water bladder to prevent excessive expansion of the bladder wall base and the resulting traction on point O' when the contents of the bladder increase or the pressure rises. This further cushions and offsets part of the torque F, effectively preventing tearing.

[0043] Further, such as Figure 4 As shown, the top of the pouch body 10 is provided with a folding portion 13 for folding, and a through hole for installing the ultrasonic treatment head 11 is opened at the center of the top, and an elastic band 14 is embedded in the edge of the through hole to facilitate opening or closing the top of the pouch body 10.

[0044] It is worth noting that the elastic band 14 is made of a flexible material, such as rubber, and has a thickness of not less than 0.1 mm.

[0045] Specifically, the thickened portion 12 and the outer wall of the bag body 10 are an integrally formed structure.

[0046] In addition, an annular mounting seat 21 is installed at the bottom of the fixed sleeve 20, and the cross-section between the side wall of the fixed sleeve 20 and the mounting seat 21 is an inverted "T"-shaped structure. The top surface of the adhesive seat 30 is provided with a mounting groove 31 that is adapted to the size of the mounting seat 21 and snap-fits. The mounting seat 21 is fixed in the mounting groove 31 by fixing screws, which is convenient for installation or disassembly.

[0047] The working principle of the ultrasonic semi-dry water bag assembly of the present invention is as follows: when in use, the operator tears off the release film at the bottom of the adhesive seat 30, adheres the adhesive seat 30 to the patient's skin to be treated, adds water or coupling liquid into the bag body 10, installs the ultrasonic treatment head 11 on the top of the bag body 10, and closes the folded part 13. The elastic band 14 is in elastic contact with the ultrasonic treatment head 11, as shown in FIG. Figure 1 As shown, ultrasonic semi-dry treatment can be performed.

[0048] In the above embodiment, the connection between the pouch body 10 and the adhesive seat 30 has an inverted T-shaped connection method, but it can be replaced by a flat and raised connection seat to achieve the corresponding technical effect, and the thickened portion 12 is arranged on the outer wall of the pouch body 10, but the thickened portion 12 can also be arranged on the inner wall of the pouch body 10, or half of it is on the outer wall of the pouch body 10 and the other half is on the inner wall of the pouch body 10 to have the same effect. Therefore, the above connection method can equally replace the corresponding connection structure in the embodiment and also belongs to the protection scope of the present invention.

[0049] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
