Description

Technical Field

[0001] The utility model belongs to the field of auxiliary water bags, and in particular relates to a special auxiliary water bag for ultrasonic diagnosis of hand tendon lesions. Background Art

[0002] Hand tendinopathy is a common clinical condition, encompassing a variety of conditions, including tendinitis, tenosynovitis, and tendon tears. Early diagnosis is crucial for the treatment of these conditions, enabling doctors to implement effective treatments and prevent further deterioration. However, existing imaging techniques have limitations in diagnosing hand tendinopathy.

[0003] First, although X-rays are widely used to examine bones and joints, they cannot clearly display soft tissue structures, such as tendons, due to their imaging principles. This makes X-rays of limited use in the early diagnosis of hand tendinopathy and unable to meet the needs of delicate surgery and treatment.

[0004] Secondly, CT scans can provide detailed anatomical information, making them highly valuable for diagnosing bone and some soft tissue lesions. However, conventional CT scans still lack the resolution to clearly visualize fine tendon structures, limiting their utility in diagnosing hand tendinopathy. Furthermore, CT scans expose patients to a certain dose of radiation, and frequent examinations can negatively impact patient health.

[0005] Ultrasound diagnosis, due to its non-invasive, real-time, portable, and economical advantages, has become a crucial tool for diagnosing hand tendinopathy. Ultrasound utilizes high-frequency sound waves to propagate through the body, generating echoes. By measuring these echoes, researchers can understand physiological and tissue structural data and morphology, identify diseases, and provide guidance. Ultrasound diagnosis is a non-invasive, painless, convenient, and intuitive diagnostic tool. B-ultrasound, in particular, is widely used and has a significant impact, being recognized as one of the four major medical imaging technologies, along with X-rays, CT scans, and magnetic resonance imaging.

[0006] Despite its numerous advantages, ultrasound diagnosis still faces challenges in practice, particularly when diagnosing uneven structures like the palm and knuckles. To ensure close contact between the ultrasound probe and the skin and obtain clear images, auxiliary devices, such as water bags, are often required. However, existing auxiliary devices suffer from unstable fixation and inconvenient operation.

[0007] A common method involves wrapping a water bag around the ultrasound head. However, this method offers uncertain fixation, adds weight to the head, and results in significant resistance to movement, impacting operational flexibility and examination efficiency. Furthermore, current auxiliary water bags typically require two-sided straps to secure them to the target location. This method is unstable and prone to slippage, compromising examination accuracy, increasing operational complexity, and prolonging testing and treatment time.

[0008] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] See also Figure 1-5 As shown, this embodiment provides a dedicated auxiliary water bag for ultrasonic diagnosis of hand tendinopathy. The bag comprises a glove body 1, a silicone sheet 2 comprising a palm portion 3, a finger portion 4, and an arm portion 5. The silicone sheet 2 is wrapped around the exterior of the glove body 1, forming a water injection space between the silicone sheet 2 and the glove body 1. An exhaust pipe 7 and a water injection pipe 6 are provided on one side of the arm portion 5. The water pipe is used to inject purified water into the water injection space within the glove. This water injection creates a good acoustic coupling environment between the glove and the hand, enhancing the transmission of ultrasonic waves.

[0032] The exhaust pipe 7 is used to exhaust the air in the water-filled space inside the glove. By exhausting the air, the bubbles inside the glove can be reduced, and the interference of the bubbles on the ultrasonic wave conduction can be reduced.

[0033] A support sheet 8 is provided inside the water injection space, which divides the water injection space into a finger chamber 10 and a palm chamber 9. By dividing the water injection hole space into the finger chamber 10 and the palm chamber 9, the size and shape of each finger chamber 10 and the palm chamber 9 can be adjusted as needed to better fit various parts of the hand. Two through holes 11 are provided on the opposite sides of the support sheet 8. A negative pressure sheet 12 is provided inside the through hole 11 for the water injection pipe 6 and the exhaust pipe 7 to enter. The negative pressure sheet 12 is a conical structure. Since the negative pressure sheet 12 is a conical structure, when the water injection pipe 6 or the exhaust pipe 7 is inserted, the cone tip will be deformed due to the entry of the pipe, and the through groove 24 opened on the opposite side of the negative pressure sheet 12 will fit tightly with the deformation of the silicone sheet 2. The inner walls of the through-groove 24 mate with each other due to the deformation of the conical silicone sheet 2, thereby sealing the through-hole 11. When the negative pressure sheet 12 assumes a conical structure, the inner walls of the through-groove 24 closely mate with each other, thereby completing the seal. The design of the through-groove 24 and the conical structure ensure that after the water inlet pipe 6 and the exhaust pipe 7 enter, the negative pressure sheet 12 can tightly wrap around the pipes, preventing any liquid or gas from leaking from the palm chamber 9 to the finger chamber 10, or vice versa.

[0034] In this embodiment, multiple silicone adsorption pads 13 are installed inside the finger portion 4, and a first elastic cord 14 is installed at the opening of the inner wall of the arm portion 5. The silicone adsorption pads 13 increase friction, ensuring that the glove fits securely to the palm during use, preventing slippage. This enhances the stability of the water bag and prevents displacement during ultrasound examinations. The first elastic cord 14 further secures the arm portion 5, reducing the risk of the glove falling off.

[0035] In this embodiment, the outer wall of the finger portion 4 is provided with spiral elastic ripples 15 from the base to the fingertip, and a second elastic cord is provided on the inner wall of the finger portion 4. These spiral corrugations increase the flexibility and stretchability of the finger portion 4, allowing the glove to better adapt to the bending and movement of the fingers, ensuring the effective propagation of ultrasonic waves through the finger portion 4. The provision of the second elastic cord further enhances the stability of the palm after inserting the water bag.

[0036] In this embodiment, the water injection pipe 6 is connected to a sealing column 16 on the outer wall of one end of the chamber, and the water injection pipe 6 is provided with a plurality of water outlet holes 17 arranged in a ring around the side of one end of the chamber. The diameter of the sealing column 16 is the same as the diameter of the water injection pipe 6, thereby completing the sealing treatment of different positions. When the palm chamber 9 is filled with water through the setting of the sealing column 16, the sealing column 16 is first inserted into the negative pressure sheet 12, and then the palm chamber 9 and the finger chamber 10 are sealed, and then water is injected. The water will remain in the palm chamber 9 and will not enter the finger chamber 10. The water injection pipe 6 is evenly distributed with a plurality of water outlet holes 17 around the side of one end of the chamber. These water outlet holes 17 are arranged in a ring, which can ensure that the water flow is evenly distributed during water injection and avoid excessive local pressure. Before performing the water injection operation, it is first necessary to insert the sealing column 16 on the water injection pipe 6 into the negative pressure sheet 12. Once the sealing column 16 is inserted into the negative pressure sheet 12, it effectively separates the palm chamber 9 from the finger chamber 10. The flexible material of the negative pressure sheet 12 tightly wraps around the sealing column 16, ensuring a tight seal between the palm chamber 9 and the finger chamber 10, preventing water leakage. Once sealed, water can be injected through the water injection pipe 6. Water then flows evenly into the palm chamber 9 through the annular outlet 17 on the water injection pipe 6. Due to the presence of the sealing column 16, water is confined to the palm chamber 9 and cannot enter the finger chamber 10.

[0037] When water is injected into the finger chamber 10, the water injection pipe 6 enters the finger chamber 10 and the main water pipe is wrapped by the petals formed by the negative pressure sheet 12, thereby completing the seal and reducing the occurrence of water entering the palm chamber 9 from the finger chamber 10 during the water injection process.

[0038] In this embodiment, a connecting cord 18 is connected to the periphery of one end of the water inlet of the water outlet pipe, and one end of the connecting cord 18 is connected to a fleece-surfaced Velcro 19. A storage slot for storing the connecting cord 18 is designed around the periphery of the outer wall of the arm portion 5 of the glove. The purpose of this storage slot is to provide a dedicated location for storing the connecting cord 18, preventing it from swinging or tangling when not in use, thereby ensuring overall neatness and ease of use. The design of the storage slot takes into account the shape and size of the arm portion 5, ensuring that the connecting cord 18 can be effectively stored without affecting the wearing and use of the glove. Furthermore, a hook-surfaced Velcro 20 is provided around the periphery of the arm portion 5, which is compatible with the fleece-surfaced Velcro 19. During use, the connecting cord 18 is removed from the storage slot, and the fleece-surfaced Velcro 19 is then aligned with the hook-surfaced Velcro 20 and secured. In this way, the position of the water outlet pipe can be firmly fixed to the arm portion 5, preventing it from moving arbitrarily due to hand movements. The combination of the fleece-surface Velcro 19 and the hook-surface Velcro 20 can not only effectively fix the position of the water outlet pipe, but also reduce the possibility of the water inlet pipe and the water outlet pipe moving randomly during operation.

[0039] In this embodiment, a one-way valve 21 is provided at the end of the exhaust pipe 7. The one-way valve 21 only allows gas to be discharged from the exhaust pipe 7, preventing water from flowing out along the exhaust pipe 7, thereby maintaining a stable water level in the water bag. A stop valve 22 is connected to the water inlet of the water inlet pipe 6, and a connecting piece 23 is connected between the exhaust pipe 7 and the water inlet pipe 6. The arrangement of the connecting piece 23 allows the water inlet pipe and the exhaust pipe 7 to move simultaneously, achieving synchronous fixation or movement.

[0040] When a patient requires an ultrasound diagnosis, they first don the appropriately sized water bag glove, ensuring a snug fit across the palm, fingers, and wrist. Then, they inject an appropriate amount of purified water into the glove through the water inlet tube. The sealing mechanism and porous design of the water inlet tube ensure that the water is evenly distributed within the glove, creating a stable water-filling space. Once filled with water, the water bag automatically elastically deforms to fill any bumps or depressions on the hand's surface, covering them. This design ensures a tight fit between the water bag and the skin, providing even pressure distribution and optimizing the transmission of ultrasound waves.

[0041] During the examination, as the hand joints move, the water inside the water bag automatically adjusts to the joint's deformation, filling the gaps created by the flexion. This ensures that the ultrasound probe maintains good contact with the hand skin, ensuring the continuity and stability of the ultrasonic signal. When the joints flex, the water bag's water bag quickly responds to the hand's deformation, automatically elastically deforming to fill the gaps created by the joints. This process is automatic, requiring no additional intervention, significantly improving the efficiency and accuracy of the examination.

[0042] The present invention is not limited to the above-mentioned embodiments. Anyone should be aware that any structural changes made under the guidance of the present invention, and any technical solutions that are the same or similar to those of the present invention, fall within the scope of protection of the present invention. The technologies, shapes, and structures not described in detail in the present invention are all well-known technologies.
