Background technology
The large transfusion bottle medically used, in order to easy to use, usually the composite cover with draw ring can be used, existing composite cover is generally made up of draw ring, rubber cushion and enclosing cover, enclosing cover is the hollow circular cylinder of a both ends open, elastic mounting at the top end opening place of enclosing cover, draw ring wherein one section be connected with elastic mounting, then enclosing cover is enclosed in large transfusion bottle bottleneck; During use, firmly pull-up draw ring, Transfusion needle pipe can insert rubber cushion and can use, more for convenience.And in production, transportation; because the spontaneous intrinsic toughness of draw ring and draw ring only have one section of characteristic be connected with rubber cushion; make draw ring often can produce the phenomenon of tilting; cause and washing embedding gear and sending in lid track and often stucking phenomena can occur; the normal progress of producing of impact, even can damage equipment time serious.On rubber cushion, puncturing hole size is the same, and which hole that is not easily distinguishable during nurse's dosing is used, and often causes same hole to be repeatedly used to dosing, thus causes rubber cushion Punching Fallen Scraps Ratio to increase.
Utility model content
The purpose of this utility model is to provide a kind of composite cover, solves draw ring in prior art and easily tilts, affects production, the shortcoming that rubber cushion Punching Fallen Scraps Ratio is higher.
A kind of composite cover, comprise inner cap, rubber cushion and enclosing cover, a cavity volume is formed between described enclosing cover and inner cap, described rubber cushion is located at cavity volume inside, described inner cap outside is provided with screw thread layer, described inner cap is threaded with enclosing cover, described rubber cushion is provided with medicine feeding hole and infusion hole, described inner cap and medicine feeding hole, infusion hole corresponding region is respectively equipped with easy pierceable region, rubber seal is respectively equipped with above described medicine feeding hole and infusion hole, described medicine feeding hole and infusion hole edge are respectively equipped with protruding circle, it is inner that described rubber seal is located at protruding circle, described projection circle outside is provided with screw thread layer, described medicine feeding hole and infusion hole are respectively equipped with seal cover, described seal cover encloses with projection and is threaded, described inner cap upper surface is provided with boss, described rubber cushion lower surface is provided with groove, described boss and groove match, described infusion hole diameter is greater than medicine feeding hole.
The utility model has the advantage of: inner cap outside is provided with screw thread layer, inner cap is threaded with enclosing cover, during use, enclosing cover can screw or outward winding, easy to use, rubber cushion is provided with medicine feeding hole and infusion hole, inner cap and medicine feeding hole, infusion hole corresponding region is respectively equipped with easy pierceable region, rubber seal is respectively equipped with above described medicine feeding hole and infusion hole, described medicine feeding hole and infusion hole edge are respectively equipped with protruding circle, it is inner that described rubber seal is located at protruding circle, infusion hole diameter is greater than medicine feeding hole, can conveniently distinguish infusion hole and medicine feeding hole, same hole is avoided repeatedly to be used to dosing, thus cause rubber cushion Punching Fallen Scraps Ratio to increase, simultaneously infusion hole and medicine feeding hole easy to use, good airproof performance, effectively avoid polluting, protruding circle outside is provided with screw thread layer, described medicine feeding hole and infusion hole are respectively equipped with seal cover, described seal cover encloses with projection and is threaded, during use, seal cover can screw or outward winding, easy to use, inner cap upper surface is provided with boss, described rubber cushion lower surface is provided with groove, described boss and groove match, add the sealing of whole composite cover, effectively prevent pollution.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of composite cover described in the utility model.
Wherein: 1-projection circle, 2-rubber seal, 3-rubber cushion, 4-infusion hole, 5-inner cap, the easy pierceable region of 6-, 7-boss, 8-groove, 9-medicine feeding hole, 10-seal cover, 11-cavity volume, 12-screw thread layer, 13-enclosing cover.
Detailed description of the invention
