Catheter hub system

Abstract

The present application relates to a kind of catheter seat systems, including catheter seat, first connecting plate and second connecting plate, the catheter seat includes first cavity, second cavity and third cavity, the first cavity and third cavity are located at the two sides of second cavity respectively, the first connecting plate connects the first cavity and second cavity, the second connecting plate connects the third cavity and second cavity, at least one suture hole is respectively provided on the first connecting plate and the second connecting plate.The catheter seat system compared with prior art, suture position is transferred to catheter seat position, the total length of entire catheter seat system can be shortened, that is, the total length of entire catheter system is also shortened, so that the volume of implant intervention system is as small as possible, and fixed position is close to catheter seat position, catheter seat can also avoid excessive micro-motion, improve the reliability of fixation.

Claims

The catheter hub includes a first cavity, a second cavity, and a third cavity. The first cavity and the third cavity are located on opposite sides of the second cavity. The first connecting plate connects the first cavity and the second cavity, and the second connecting plate connects the third cavity and the second cavity. The first connecting plate and the second connecting plate are each provided with at least one suture hole. The first connecting plate includes a first suture hole, and the second connecting plate includes a second suture hole; The edge of the first connecting plate includes a curve, the edge of the first connecting plate is concave, and the line connecting the position of the maximum curvature of the edge of the first connecting plate and the position of the first suture hole closest to the edge of the first connecting plate passes through the center of the first suture hole; and / or, the edge of the second connecting plate includes a curve, the edge of the second connecting plate is concave, and the line connecting the position of the maximum curvature of the edge of the second connecting plate and the position of the second suture hole closest to the edge of the second connecting plate passes through the center of the second suture hole.

2. The catheter hub system of claim 1, wherein, The line connecting the center of the first suture hole and the center of the second suture hole is substantially perpendicular to the axis of the second cavity.

3. The catheter hub system of claim 1, wherein, The angle between the first cavity and the second cavity is between 30° and 60°, and the angle between the third cavity and the second cavity is between 30° and 90°.

4. The catheter seat system according to claim 1, characterized in that, When the connection position of the first cavity and the second cavity is at the same position in the axial direction as the connection position of the third cavity and the second cavity, the first connecting plate is located at the proximal end of the connection position of the first cavity and the second cavity, and the second connecting plate is located at the proximal end of the connection position of the third cavity and the second cavity.

5. The catheter seat system according to claim 1, characterized in that, The first connecting plate and the second connecting plate are coplanar with at least one side of the first cavity, the second cavity and the third cavity.

6. The catheter hub system according to claim 1, characterized in that, The first connecting plate and / or the second connecting plate are respectively provided with a plurality of stitching holes.

7. The catheter seat system according to claim 1, characterized in that, The first connecting plate and / or the second connecting plate are detachably mounted on the conduit seat.

8. The catheter seat system according to claim 1, characterized in that, The first connecting plate and / or the second connecting plate include a connecting area and an enlarged area. The conduit seat includes several receiving portions. The enlarged area is a flexible area. In the initial state, the enlarged area is folded and stored in the receiving portion.

9. The catheter seat system according to claim 8, characterized in that, The receiving portion includes a positioning member of variable length, the edges of which are fixed to both sides of the positioning member to control the extendable length of the enlarged area.
