Problems solved by technology

[0004] VSD can maintain effective drainage for 4-7 days, and multiple debridements can be performed on patients. During daily activities and rest, patients will inevitably touch or passively rub against the drainage tube and semipermeable membrane of VSD, which may cause the semipermeable membrane Falling off or the drainage tube being dragged down will affect the smooth drainage and drainage, cause wound infection or abscess, and the patient's condition will be repeated and the curative effect will be unstable, which is not conducive to the early recovery of the patient

Embodiment 1

[0042] combine figure 1 , a wound care compression device for mammary glands, the exterior of the device is designed in a circular arc shape to avoid the edges and corners from hurting the skin, and it is made of skin-friendly materials, including a fixed ring 1 and a fixed ring 2 2 arranged with the axis coincident. The fixed ring one 1 and the fixed ring two 2 are connected by an arc-shaped protective plate 3, and the described protective plate 3 includes an inner plate and an outer plate that is relatively slidably connected along the outer side wall of the inner plate, so that the protective plate can be adjusted according to the body shape of the patient. adjustment, to adapt to the needs of different patients, the first fixed ring and the second fixed ring are strip-shaped structures, the free ends of the first fixed ring and the second fixed ring are connected with buckles for length adjustment, the fixed The sidewalls of the ring 1 and the fixing ring 2 are provided wi...

Embodiment 2

[0047] On the basis of Example 1, combined with Figure 6-8 , the outer wall of the protective plate 3 is provided with a groove 7 that is concave to the inside of the protective plate 3 and turns in an S shape. The groove 7 is provided with a bending limiting assembly 8 for accommodating a drainage tube, and the drainage tube Inserted into a plurality of mutually nested bending limiting components 8 to avoid bending damage of the drainage tube, the bending limiting component 8 includes a restraint part 81 and a lock and part 83, and between the restraint part 81 and the lock and part 83 They are connected by an arc of a transition part 82, and the restriction part 81, the transition part 82 and the locking part 83 have a coaxial cavity enclosing the drainage tube.

[0048] The outer diameter of the constraint portion 81 is smaller than the lock portion 83, and between the adjacent parts of the plurality of connected bending limiting components 8, the constraint portion 81 of ...

Embodiment 3

[0051] On the basis of Example 1, combined with Figure 9 with Figure 10 , the protective plate 3 moves along the outer edges of the fixed ring one 1 and the fixed ring two 2 through a positioning mechanism, and the positioning mechanism includes a movable part 10 connected to the fixed ring one 1 and a sliding block 9 connected to the fixed ring two 2, The sliding block 9 is relatively slidably connected along the outer periphery of the second fixed ring 2 .

[0052] The movable part 10 includes a support platform 11 that fits the outer edge of the fixed ring one 1 and a positioning block 12 that is bolted to the fixed ring one 1 and adapted to the support platform 11, and the support platform 11 is far away from one end of the positioning block 12 A protruding wing 16 is provided, and the positioning block 12 is provided with a curved rack 14 near the inner side wall of the supporting platform 11. The protruding wing 16 of the supporting platform 11 is provided with a gear...

Abstract

The invention relates to a wound nursing and pressing device for mammary gland. The device comprises a first fixing ring and a second fixing ring, the axes of the first fixing ring and the second fixing ring coincide, the first fixing ring and the second fixing ring are connected through an arc-shaped protection plate, the protection plate moves along the outer edges of the first fixing ring and the second fixing ring through a positioning mechanism, and the protection plate is connected with a limiting mechanism used for fixing a drainage tube. According to the wound nursing and pressing device, the drainage tube and a biological sealing semi-permeable membrane can be effectively positioned, the phenomena of loosening and falling are avoided, meanwhile, the drainage tube is prevented from being flattened, and smooth drainage is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a wound care compression device for mammary glands. Background technique [0002] Vacuum sealing drainage technology (Vacuum sealing drainage, VSD) is to use polyurethane, polyvinyl alcohol and other materials or composite materials containing drainage channels to fill the wounds formed after skin or soft tissue infection, defect, and necrosis. Drainage is changed to all-round drainage; then bio-semipermeable membrane is used to seal the filling material, forming a closed space, isolating the wound surface from external polluted environment, and eliminating chances of infection. Finally, the drainage tube is connected to a negative pressure source to suck out the cavity, Wound secretions and necrotic tissue promote local blood circulation, which is conducive to the uniform and orderly growth of granulation tissue and accelerates wound healing. [0003] Compar...
