Problems solved by technology

When the patient is at home or in a sleep state, he may unconsciously scratch the arteriovenous fistula on the arm. After turning over, the body or head may press the arteriovenous fistula on the arm. Unconscious scratching or prolonged Compression may cause irreversible damage to arteriovenous fistulas
Re-operation or repair of arteriovenous vascular fistula may face patients with no replacement blood vessels, waiting for blood vessels to grow after surgery, and a long cycle suitable for hemodialysis flow (usually vascular fistula can be used after 3-6 months), and temporary alternatives may cause A series of problems such as severe infection and hemorrhage and other serious complications will affect the quality of life of patients and reduce the expected survival time of patients in advance

Embodiment 1

[0034] see Figure 1 to Figure 6 As shown, this embodiment provides a vascular fistula protection device including an upper pillow 1, a lower pillow 2 and a connecting part 3; the upper pillow 1 has an upper pillow hollow 11 structure, and the lower pillow 2 has a lower pillow hollow 21 structure, the hollow structure can be in various forms such as circular hollow, square hollow and irregular structure hollow, which can achieve the functions of ventilation and stable support. The upper pillow body 1 is provided with an upper receiving groove 41, and the lower pillow body 2 is provided with a lower receiving groove 42 corresponding to the upper receiving groove 41. After the upper receiving groove 41 and the lower receiving groove 42 are fastened together, a through hole 4 is formed, which can pass through the human arm. , the upper receiving groove 41 and the lower receiving groove 42 in this embodiment are fastened to form a through hole 4 with an oval cross section to bette...

Embodiment 2

[0038] see Figure 7 , this embodiment provides a vascular fistula protection device, the specific scheme of the upper pillow body 1, the lower pillow body 2 and the connecting part 3 is the same as that of embodiment 1, and will not be repeated in this embodiment; preferably, the blood vessel of this embodiment The fistula protection pillow also includes a liner 5 detachably connected inside the through hole, and the liner 5 is detachably connected with the inner wall of the through hole 4 through a Velcro structure. Specifically, the material of the liner 5 can be polyurethane slow-rebound sponge. One side of the liner 5 is provided with a velcro hook surface, and the inner wall of the through hole 4 is provided with a velcro suede surface. The hook surface and the suede surface can be glued together. catch. During use, if the through hole 4 of the pillow body is larger for the patient, the liner 5 can be embedded in the through hole 4 to reduce the aperture of the through ...

Embodiment 3

[0040] see Figure 8 and Figure 9, this embodiment provides a vascular fistula protection device, the upper pillow body 1 is provided with a first fastening part 12, and the lower pillow body 2 is provided with a second fastening part 22 at a position corresponding to the first fastening part 12 , the first fastening part 12 and the second fastening part 22 can be corresponding mortise and tenon structures, and the mortise and tenon joints are engaged with each other during fastening, so that the upper pillow body 1 and the lower pillow body 2 are firmly matched and are not easy to displace and move. Other structures of this embodiment are the same as those of Embodiment 1 and Embodiment 2, and will not be repeated here.

Abstract

The invention discloses a vascular fistula protection device. The device comprises an upper pillow body, a lower pillow body and connecting components, wherein an upper accommodating groove is formedin the upper pillow body, and the whole upper pillow body is of a hollowed-out structure; a lower accommodating groove corresponding to the upper accommodating groove is formed in the lower pillow body, and the whole lower pillow body is of a hollowed-out structure; when the upper pillow body and the lower pillow body are buckled, the upper accommodating groove and the lower accommodating groove form a through hole capable of accommodating an arm of a human body; the connecting components are detachably connected with the upper pillow body and the lower pillow body. The device can protect internal fistula of artery and vein blood vessels, prolong the service life of the internal fistula, guarantee smooth dialysis and improve the life quality of patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a vascular fistula protection device. Background technique [0002] At present, there are about 1.5-1.8 million renal replacement therapy patients in my country, mainly hemodialysis patients. Arteriovenous fistula is the most commonly used vascular access for hemodialysis, and it is the "lifeline" for maintaining hemodialysis patients. Usually patients undergo hemodialysis treatment 1-3 times a week through the arteriovenous vascular fistula, each time lasting at least 4 hours. In daily life, the nursing of arteriovenous fistula and the comfort of the arm during the dialysis process and the maintenance of dialysis are the difficulties of daily medical care and serious life problems. When the patient is at home or in a sleep state, he may unconsciously scratch the arteriovenous fistula on the arm. After turning over, the body or head may press the arteriovenous fistula o...
