Disposable self-venting and liquid-stopping infusion set and method

Abstract

The invention discloses a disposable automatic exhausting and liquid stopping infusion device and a method. The infusion device comprises an upper cavity of the infusion device and a lower cavity of the infusion device. The upper cavity of the infusion device and the lower cavity of the infusion device are connected in an embedded mode and are connected in a sealed mode. An air filtering membrane is designed at the upper portion in an inner cavity formed by the upper cavity of the infusion device and the lower cavity of the infusion device, and a liquid medicine splitter plate is installed below the air filtering membrane. A liquid medicine filtering membrane is arranged at the upper end of the lower cavity of the infusion device, a liquid stopping floating piece can be installed at the lower end of the lower cavity of the infusion device, and a liquid outlet connector is connected to the liquid outlet position of the lower cavity of the infusion device. According to the disposable automatic exhausting and liquid stopping infusion device and the method, under the splitting and stressing action of the liquid medicine splitter plate, residual air bubbles of liquid medicine are filtered out and eliminated through the air filtering mebrane and an exhaust opening formed in the upper cavity of the infusion device. The disposable automatic exhausting and liquid stopping infusion device and the method can be widely applied to infusion of clinic center venous catheters, periphery intervention central veins and the like.

Description

1. Technical field [0001] The invention belongs to an infusion device used for intravenous infusion for clinical patients in the medical and health field, and in particular relates to a disposable infusion device and method capable of precisely filtering air and gas bubbles during intravenous infusion, safe infusion and medication. 2. Background technology [0002] At present, in medical clinics, blood transfusion, infusion or drug injection through venipuncture is the most common method in the process of treating patients with clinical diseases. Yet existing medical staff is in the treatment that carries out venous puncture blood transfusion, transfusion or drug injection to clinical patient, usually is intravenous infusion. In the process of treating patients with clinical diseases, the existing common infusion sets still have the disadvantages of injecting the air and gas bubbles left in the liquid medicine into the body of patients with clinical diseases to varying degre...
