Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a split-type silicone cupping capsule. Background Technology

[0002] Traditional cupping therapy, a time-honored external treatment method in Traditional Chinese Medicine, uses negative pressure to adhere to the body surface, achieving the effects of promoting blood circulation, removing blood stasis, and relaxing muscles and tendons. Currently, common cupping tools mainly include glass, plastic, and silicone cups. Among them, silicone cups are gradually becoming a commonly used tool in homes and clinics due to their ease of use and durability.

[0003] However, existing silicone cupping sets still have the following technical shortcomings. They are functionally limited; commercially available cupping sets only have therapeutic functions and lack storage designs for accessories, requiring users to carry additional items such as eye masks and essential oils, resulting in poor usability. They also have poor adaptability; traditional cupping sets typically use a uniform diameter and wall thickness, which cannot simultaneously meet the high-strength support required for areas with thicker fat (waist, buttocks) and the flexible fit required for curved joint surfaces (neck, knees), leading to unstable suction or skin discomfort. For example, the buttocks, with their thicker fat, require a larger suction area and more uniform pressure, while joint areas require greater deformation capacity to avoid stiffness or air leakage, failing to simultaneously meet the needs of fat layer support and joint mobility.

[0004] Therefore, this invention provides a split silicone cupping capsule that can adapt to different body surface characteristics, optimize pressure distribution, and improve airtightness to meet the diverse needs of modern physiotherapy scenarios. Utility Model Content

[0005] To address the problems of poor single-diameter adaptability, uneven pressure distribution, insufficient airtightness, and limited reset function in existing silicone cupping testing technologies, a split-type silicone cupping capsule has been designed.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a split silicone cupping capsule, including a capsule body with a hollow structure of semicircular ends and a cylindrical middle section, which is laterally separated into a symmetrical upper cover and a lower cover along the middle section. The upper cover and the lower cover are connected by a retaining ring. After the upper cover and the lower cover are closed, they form a complete capsule shape, which is convenient for carrying and storage.

[0007] Preferably, the upper and lower covers can be used independently for cupping after separation. The upper cover has a concave, smooth silicone lip at the opening end, and the lower cover has a convex, smooth silicone lip at the opening end.

[0008] Preferably, the wall thickness of the main body and bottom of the top cover is 3mm, the wall thickness of the opening area is increased to 4.4mm, and the wall thickness of the transition area is 3.3mm.

[0009] Preferably, the wall thickness of the main body and bottom of the lower cover is 3mm, the wall thickness from the bottom to the retaining ring position is increased to 4mm, the wall thickness of the opening area is 3.5mm, the wall thickness of the secondary pressure-bearing area is 2.5mm, and the thickness of the edge of the opening end is 2.5mm.

[0010] Preferably, the upper cover and the lower cover have an integrally formed ear-shaped protrusion on the right side of the opening end, and the protrusion has a coaxial through ear hole in the center for connecting the retaining ring.

[0011] Preferably, the retaining ring passes through the ear holes of the upper and lower covers, forming a rotatable hinge structure. Pressing the rotating part of the retaining ring to form a notch can actively release the connection with the ear holes of the upper and lower covers.

[0012] Preferably, the retaining ring is made of elastic metal or reinforced plastic, and after assembly, it forms a clearance fit with the ear hole to ensure smooth rotation.

[0013] The beneficial effects of this utility model are:

[0014] (1) The split silicone cupping capsule of this utility model has a split capsule-shaped structure and a differential wall thickness gradient design for the upper and lower caps. It provides elastic buffering during negative pressure adsorption, promotes local blood circulation and tissue repositioning, takes into account the needs of fat layer support and joint movement, and also realizes the storage function.

[0015] (2) The split silicone cupping capsule of this utility model has a hollow capsule body with two semi-circular ends and a cylindrical middle section. It can store auxiliary products such as eye masks and essential oils, avoiding the need to carry an extra storage box and making it convenient for home or travel use. The differentiated wall thickness design of the symmetrical upper and lower cover separated horizontally along the middle section is suitable for different body parts. The upper cover (thick opening 4.4mm) is suitable for areas with thicker fat (waist, buttocks), enhancing the anti-collapse ability and maintaining stable suction. The lower cover (thin edge 2.5mm) fits the joints and curved parts (neck, shoulders, limbs), improving comfort and suction effect.

[0016] (3) The split silicone cupping capsule of this utility model is easy to squeeze and expel air through the thin wall area (3mm), and is used in conjunction with the ear hole to assist in lifting, which enhances the negative pressure adsorption efficiency, allowing a single person to complete the treatment of difficult-to-operate areas such as the back; at the same time, the snap ring hinge design enables quick disassembly and assembly, ensuring a leak-proof seal when closed, and also supports 180° rotation, making it easy to clean and store; the ear-shaped protrusion breaks the symmetry of the cylinder, preventing it from rolling when laid flat.

[0023] To make the technical means, technical features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] A capsule-shaped silicone cupping device is shaped like a hollow capsule with semicircular ends and a cylindrical center (similar to a pill). The capsule can be separated into a symmetrical upper and lower cover along the middle, and the opening and closing mechanism uses a snap ring connection to ensure a stable and sealed opening and closing.

[0025] The hollow cavity of the capsule (approximately 5-8cm in diameter and 10-15cm in length) is used to store rolled-up eye masks or other small items (such as massage rollers, essential oil bottles, etc.). The inner wall can be equipped with anti-slip stripes or elastic pads to secure the contents. After the upper and lower caps are separated, they can be used independently for cupping. The opening edge of the cup has a smooth silicone lip to ensure a comfortable and airtight fit when in contact with the skin.

[0026] The main body and bottom area of ​​the top cover have a thinner wall thickness (3mm), which makes it easier for users to squeeze and expel air to generate negative pressure, while maintaining sufficient elasticity to maintain suction. The wall thickness of the opening area (the end that contacts the skin) is increased to 4.4mm to enhance structural strength and prevent collapse due to suction. The wall thickness of the transition area changes gradually, with the wall thickness of the secondary pressure area near the opening being 3.3mm, to avoid stress concentration. The top cover is mainly suitable for areas with thicker fat (such as the buttocks and waist).

[0027] The lower cover and bottom area have a relatively thin wall thickness (3mm), which makes it easy to squeeze and expel air, maintaining basic suction power. The wall thickness gradually increases to 4mm from the bottom to the retaining ring, enhancing the strength of the connection structure. The wall thickness of the opening area (the end that contacts the skin) is reduced to 3.5mm, a medium thickness that balances suction power and flexibility. The wall thickness of the secondary pressure-bearing area near the opening is set at 2.5mm, an ultra-thin design that better fits curved surfaces. At the same time, the thickness of the opening edge is set at 2.5mm, extremely flexible, and adaptable to bone protrusions. The lower cover is mainly suitable for joints or curved areas (such as the shoulders, neck, and limbs).

[0028] In this embodiment, an integrally formed ear-shaped protrusion is provided on the right side of the opening end of the upper cover and the lower cover (near the middle of the capsule). The protrusion has a coaxial through ear hole (diameter 4-6mm) in the center, ensuring that it can be operated by either hand when used separately.

[0029] In this embodiment, the ear holes of the upper and lower covers are mirror-symmetrical, and the two ear holes overlap when the capsule is closed, and can be fixed together by hanging ropes.

[0030] In this embodiment, the retaining ring passes through both the upper and lower cover ear holes and is locked by a snap fastener to form a rotatable hinge structure; pressing the rotating part of the retaining ring causes it to retract radially, thereby releasing the lock and separating the upper and lower covers.

[0031] In this embodiment, during cupping, fingers are inserted into the ear canal to assist in lifting and enhancing the efficiency of air release (especially suitable for thick-walled areas).

[0032] In this embodiment, the ear hole protrusion breaks the cylindrical symmetry of the capsule, which can prevent it from rolling when placed flat.

[0033] In this embodiment, the capsule is made of medical-grade silicone (Shore A40-50 hardness), which is heat-resistant and sterilizable. During injection molding, the non-uniform wall thickness is controlled by the mold, and the transition area is smooth without sharp corners.

[0034] Working principle: It adopts a symmetrical split structure, and the upper cover 1 and lower cover 2 can be detached and combined through the central retaining ring. When closed, it forms a complete capsule shape, providing storage function; when separated, it forms two independent cupping units. For areas with thicker fat (such as waist and buttocks), the upper cover 1 is used to resist tissue pressure. For joints or curved areas (such as shoulders, neck and limbs), the lower cover 2 is used to adapt to the bone contour. The thin wall area (3mm) is squeezed to expel the internal air. The silicone rebound generates negative pressure, and the smooth lip 4 forms a seal with the skin, realizing seamless switching between storage and treatment functions, and accurately adapting to different parts of the human body.
