BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a syringe connection port according to the present invention will be described with reference to the drawings.
[0014]
As shown in FIG. 1, a syringe connection port 10 according to the first embodiment of the present invention includes a seal valve body 11 constituting a valve, and a cap member having a sleeve into which a mouth of a twist lock type syringe can be inserted. 12, an adapter 13, and a rubber valve 14, which are provided in the co-infusion tube 200.
[0015]
As shown in FIGS. 1 and 2 (a) and 2 (b), the co-infusion tube 200 is a pipe provided in the middle of the infusion pipe, and has connection portions 203 and 204 for connecting two pipes 201 and 202 of the infusion pipe at both ends. It has. A branch portion 205 is provided at the center of the co-infusion tube 200, and an opening 206 is formed so as to face the branch portion 205. The opening 206 has a cylindrical wall portion 207 for mounting the seal valve body 11 described later of the syringe connection port 10 and a seating portion 208 for seating the seal valve body 11. An outer peripheral flange 209 for mounting a cap member 12 of the syringe connection port 10 described later protrudes in an outer radial direction from an outer peripheral edge of an upper end of the wall 207.
[0016]
As shown in FIGS. 3A and 3B, the seal valve body 11 is a substantially disk-shaped member formed of an elastic body such as silicone rubber, and the mouth of the syringe is provided at the center of the seal valve body 11. An insertion portion 15 for insertion is formed.
[0017]
The insertion portion 15 is, as shown in an enlarged manner in FIG. 3C, an upper surface of the seal valve body 11 (disposed so as to face the outside of the mixed injection tube 200 when attached to the opening 206 of the mixed injection tube 200). A groove 17 having a predetermined depth is formed in the groove 16 in a straight line, and a seal valve (disposed so as to face the inside of the mixed injection tube 200 when attached to the opening 206 of the mixed injection tube 200) is formed at the bottom of the groove 17. A small-diameter hole 19 penetrating the lower surface 18 of the body 11 is formed.
[0018]
Both ends 17a in the longitudinal direction of the groove 17 are cut into a V-shape as shown in an enlarged manner in FIG. Accordingly, when the insertion portion 15 is brought into the pressure-sealed state, the tightness of both ends 17a of the groove 17 is good, so that seepage or leakage of the liquid can be suppressed.
[0019]
It is desirable that the depth of the groove 17 formed at the center of the seal valve body 11 is about １ ／ to ／ of the thickness of the center part of the seal valve body 11. The groove 17 may be formed at the time of molding a mold for molding the seal valve body 11. When the small-diameter hole 19 formed at the bottom of the groove 17 of the seal valve body 11 is formed by piercing a conical needle, chips of silicone rubber do not occur at the opening of the small-diameter hole 19 and the small-diameter hole 19 is opened. Finishes neatly. The outer diameter 20 of the seal valve element 11 is slightly larger than the inner diameter of the cylindrical wall 207 so that the seal valve 11 can be pressed into the cylindrical wall 207 of the opening 206 of the co-infusion tube 200. The central portion of the lower surface 18 of the seal valve body 11 has an arch-shaped concave shape 21.
[0020]
As shown in FIG. 4, when the seal valve element 11 is mounted on the co-infusion tube 200, the seal valve element 11 is compressed in the radial direction by the cylindrical wall portion 207 of the co-infusion tube 200. Large compressive stress occurs. Furthermore, since the central portion of the lower surface 18 of the central portion of the seal valve body 11 has an arch-shaped concave shape 21, a greater compressive stress acts near the insertion portion 15. In particular, a larger compressive stress is generated in the central portion of the seal valve body 11 on the lower surface 18 side of the seal valve body 11 where the small diameter hole 19 is formed than on the upper surface 16 side. Due to this compressive stress, the insertion portion 15 of the seal valve element 11 is in a press-fit sealed state.
[0021]
Next, the cap member 12 is a member attached to the outer peripheral flange portion 209 so as to cover the opening 206 of the mixed injection tube 200. An opening 22 is formed in the center of the cap member 12 so that the insertion portion 15 of the seal valve body 11 can be seen, and a sleeve portion 23 is provided upright so as to surround the periphery of the opening 22.
