Puncture connector type transfusion device

Abstract

The invention provides a puncture connector type transfusion device. The transfusion device comprises a transfusion conduit and a venous transfusion needle, wherein a venous transfusion needle holder is arranged on the venous transfusion needle; a bottle cap puncture outfit is arranged at the front end of the transfusion conduit, a connecting tube is arranged between the transfusion conduit and the venous transfusion needle; an outer conical connector matched with the venous transfusion needle holder is arranged at the rear end of the connecting tube; a rubber plug cap is arranged at the front end port of the connecting tube; a branch tube is connected with the connecting tube below the rubber plug cap, and is connected with the transfusion conduit by virtue of a one-way valve; the joint between the branch tube and the connecting tube is less than 10cm from the one-way valve, and is less than 15cm from the outer conical connector. According to the puncture connector type transfusion device, the rubber plug cap on the connecting tube is punctured by an injection needle for quickly dosing, a liquid medicine can be prevented from returning due to the one-way valve on the branch tube at the front end of the connecting tube, so that the liquid medicine can be transfused into a human body quickly, so that time is gained for saving a patient. The puncture connector type transfusion device is reasonable in design and simple in operation, and can be used for facilitating medicine injection and preventing the occurrence of liquid medicine return.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a puncture connector type infusion set. Background technique [0002] Clinically, there are often situations that require rapid dosing of drugs, such as infusion reactions such as allergies and shock during infusion of patients, and emergency department rescue of patients. Usually, nurses disconnect the connection between the venous needle and the infusion catheter, and start from the venous needle seat. Drugs are pushed intravenously, but this method will cause bubbles to be generated when the venous needle is reconnected to the infusion catheter, and the operation is troublesome, which increases the workload of the nurses and even delays the best time for rescue. There have been infusion sets with injection parts before, but when adding medicine from the injection part, the liquid medicine tends to flow upwards and cannot quickly enter the human body. The invention provides a...

[0002] Clinically, there are often situations that require rapid dosing of drugs, such as infusion reactions such as allergies and shock during infusion of patients, and emergency department rescue of patients. Usually, nurses disconnect the connection between the venous needle and the infusion catheter, and start from the venous needle seat. Intravenously push the drug, but this method will cause air bubbles when the venous needle is reconnected to the infusion catheter, and the operation is troublesome, which increases the workload of the nurses and even delays the best time for rescue
