Three-valve cover of infusion bottle and infusion bag for purposes of injection and flushing

Abstract

The invention discloses a three-valve cover of an infusion bottle and an infusion bag for purposes of injection and flushing. The three-valve cover comprises an inner cover which is fixedly connected to an opening of an infusion bottle in a welded-sealing mode, wherein an outer cover is fixed to the surface of the inner cover in an embedded mode; openings A for achieving ventilation and for dropping liquid, are formed in one side of the top of the inner cover; openings B for pouring off liquid in the infusion bottle are formed in the positions, between the openings A, at the other side of the top of the inner cover; the outer cover, in correspondence to the positions of the openings A, is provided with a horizontal pulling rod; and the outer cover, in correspondence to the positions of the openings B, is provided with a vertical pulling rod. With the application of the three-valve cover provided by the invention, the infusion bottle and an infusion bag provided with the cover body structure can be used for conducting infusion, and meanwhile, the infusion bottle and the infusion bag can be used for cleaning as well, so that the current situation that existing clinical infusion bottles and infusion bottles are produced, circulated and used in a separated mode; and a medical institution can implement the infusion and cleaning just by virtue of the infusion bottle and the infusion bag provided with the cover body structure, so that clinical application is facilitated and the cost of the medical institution is reduced.

Description

technical field [0001] The invention relates to the field of caps of infusion bottles, in particular to a three-valve cap for an infusion bottle and an infusion bag for two purposes of injection and flushing. Background technique [0002] Physiological saline refers to a solution such as sodium chloride, which is commonly used in physiological experiments or clinically and has an osmotic pressure equal to that of animal or human plasma. The concentration of sodium chloride injection that people usually use for infusion is 0.9%, which can be used as normal saline. Its osmotic pressure is similar to that of human blood, and its sodium content is also similar to that of blood plasma, but its chlorine content is significantly higher than that of blood plasma. Therefore, physiological saline is only relatively physiological, and its purpose is to supply electrolytes and maintain the tension of body fluids. It can also be used externally, such as when cleaning wounds or changing ...

Problems solved by technology

This leads to a large difference in the structure of the bottle cap

As a result, although the solutions in the bottle are both physiological saline, they cannot be mixed due to the limitation of the cap structure of these two different functions of physiological saline.

Moreover, there is no physiological saline product that can be applied to both infusion and cleaning in the technical field at present.

As a result, medical institutions need to produce, circulate and use physiological saline bottles and saline bags according to the different functions of infusion and cleaning, which is inconvenient for clinical use and increases the cost of medical institutions
