This utility model discloses a novel sheath, relating to the field of medical device technology. It includes an inner and outer tube body and a sheath. The tube body comprises an inner tube, a reinforcing layer, and an outer tube, sequentially arranged from the inside out. The outer tube includes multiple transition segments connected in series. From the distal end to the proximal end of the tube body, the hardness of the multiple transition segments increases sequentially. Each transition segment has a fusion-fitting portion at its end, where the fusion-fitting portions of any two adjacent transition segments interlock to form a transition zone. By providing fusion-fitting portions at the ends of the transition segments, any two adjacent transition segments can be fused together through the fusion-fitting portions, thereby balancing support and flexibility, ensuring smooth pushing of the sheath, and providing sufficient support to guide catheters or other vascular devices to the lesion area.

A garment is disclosed that includes one or more selectively openable closure assemblies configured to provide controlled access to targeted anatomical regions of a wearer while maintaining overall garment coverage. The garment body, which may be a top, bottom, or unitary garment, incorporates at least one closure assembly extending between two regions of the garment. Each closure assembly comprises mateable closure elements, such as interlocking zipper teeth, and at least a first slider and a second slider independently positionable to couple or uncouple the mateable elements. Movement of the sliders creates selectively openable access areas that expose portions of the wearer's body, enabling medical procedures such as accessing implanted ports, vascular devices, infusion sites, or sensor modules. Independent slider positioning further defines a gap through which medical tubing, catheters, or cables may be routed without crimping. The garment enhances comfort, modesty, and functionality during medical treatment or monitoring.

This utility model discloses a vascular closure device wire forming machine, relating to the field of vascular closure device processing technology. It includes a forming operating table and auxiliary components. The forming operating table is an integrated structure, with a support base mounted on its lower surface. The auxiliary components are located on the upper surface of the forming operating table and include a support column, a support groove, a wire feeding mechanism, a wire straightener, a fixing column, a limiting support cylinder, a laser rangefinder, and a PLC control panel. The support column is located on the right side of the forming operating table. This vascular closure device wire forming machine, through the auxiliary components, enables automatic wire feeding, ensuring stable wire movement and preventing deviation during feeding. It allows real-time monitoring of the length of each wire segment to ensure consistent wire quality. The forming components enable bending and automatic cutting of the wire, improving overall processing efficiency.
