Draw ring combination cover for transfusion container and transfusion container

Abstract

The invention discloses a draw ring combination cover for a transfusion container and a transfusion container. The draw ring combination cover for a transfusion container comprises an outer cover, a rubber plug and an inner sealing cover; the outer cover is provided with a pull ring; the pull ring, a tearing zone, the rubber plug and the inner sealing cover are vertically and correspondingly arranged to form a line to be punctured; the position to be punctured in the lower surface of the rubber plug is provided with an upper sinking groove; a clearance distance is kept between the upper groove bottom of the upper sinking groove and the position to be punctured in the inner sealing cover; or the position to be punctured in the upper surface of the inner sealing cover is provided with a lower sinking groove; a clearance distance is kept between the lower groove bottom of the lower sinking groove and the position to be punctured in the lower surface of the rubber plug; or the position to be punctured in the lower surface of the rubber plug is provided with an upper sinking groove, the position to be punctured in the upper surface of the inner sealing cover is provided with a lower sinking groove, and a clearance distance is kept between the upper groove bottom of the upper sinking groove and the lower groove bottom of the lower sinking groove. By means of the draw ring combination cover for a transfusion container, scraps brought to the transfusion container during puncture process are reduced or even avoided so as to reduce insoluble particles in the transfusion solution and to guarantee transfusion safety.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pull-ring combination cover for an infusion container. In addition, the present invention also relates to an infusion container comprising the above-mentioned pull-ring combination cap for the infusion container. Background technique [0002] Infusion solution is a large dose (more than 50ml for one administration) injection solution dripped into the body by intravenous drip, usually packaged in a glass or plastic infusion solution container. When in use, the drip rate is adjusted through the infusion set, and it enters the vein continuously and steadily to replenish body fluids, electrolytes or provide nutrients. Because of its large dosage and directly into the blood, it requires high quality and high production technology. [0003] In recent years, studies at home and abroad have found that insoluble particles in medicinal liquid will inevitably enter the human bod...
