Safe infusion apparatus capable of randomly placing normal infusion

Abstract

The invention discloses a safe infusion apparatus capable of randomly placing normal infusion, and belongs to the technical field of medical apparatuses. A fixing case formed by defining a top plate and side plates is additionally arranged inside a dripping cup; the lower end surface of the fixing case is in tight contact and fixedly connected with the dripping cup; a through hole extending to the bottom is formed in the side wall of the fixing case; a filtering membrane is additionally arranged in the position of the through hole; a cavity defined by the filtering membrane and the fixing case is a medicine liquid filtering cavity; a cavity formed between the medicine liquid filtering cavity and the dripping cup is a liquid inlet cavity; a medicine liquid puncture needle is communicated with the liquid inlet cavity; an outlet of the dripping cup is communicated with the medicine liquid filtering cavity. The end surface of one end, connected with the dripping cup, of a liquid outlet pipe is flushed with the upper end surface of the outlet of the dripping cup or is positioned under the upper end surface to form a passage without medicine liquid residue. On the premise of enabling not to cause any damage to the human body, medicine liquid in the dripping cup is totally infused into the human body; the waste of the medicine liquid is reduced; the environment pollution is reduced; the energy is saved; the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an infusion set, in particular to a safety infusion set which can place normal infusion at will. Background technique [0002] The infusion set is one of the commonly used medical devices in hospitals. It is mainly used for gravity intravenous infusion. Under the action of atmospheric pressure, the liquid in the infusion bag or infusion bottle flows into the drip pot, and the liquid flows into the vein along the infusion tube. Generally, after the liquid infusion in the infusion bag or infusion bottle is completed, the nursing staff needs to change the liquid or pull out the needle in time, otherwise there will be a phenomenon of backflow of blood when the medicine is empty. If the air enters the infusion tube, it will form an air embolism after entering the human body, and the blood will not circulate smoothly, thus causing harm to the human body.

Problems solved by technology

However, since the hydrophilic membrane is located at 2 / 3 of the height inside the drip pot, there will be a surplus of liquid medicine inside the drip pot when the infusion is completed, which cannot be used up, resulting in waste of liquid medicine, and directly throwing it away will pollute the environment
