Description

Multi-purpose disposable infusion set

technical field

The utility model relates to a medical device, which belongs to the improvement of an intravenous injection device, in particular to a multipurpose disposable infusion device.

Background technique

At present, when medical units provide patients with intravenous infusion, the structure of the disposable infusion set used is that the cork puncture needle is connected to the drip funnel through the infusion tube, a filter is installed in the drip funnel, and the liquid outlet of the drip funnel passes through the infusion tube. A venipuncture needle is connected, and a regulator is installed on the infusion tube connecting the drip funnel and the venipuncture needle. The disposable infusion set can conveniently and safely perform infusion therapy for patients. But when carrying out transfusion treatment to the patient, an infusion set can only transfuse a kind of medicinal liquid. In the liquid medicine treatment process, when different liquid medicines need to be input, if the cork puncture needle is pulled out from the bottle stopper of the former liquid medicine bottle, the bottle stopper puncture needle is punctured on the bottle stopper of the new liquid medicine bottle again, like this It is easy to cause contamination of the liquid medicine. Different infusion sets are used when transfusing different medicinal liquids, which not only increases the number of punctures to the patient's veins, but also consumes many medicinal liquid sets. In addition, when it is necessary to temporarily increase intravenous administration or rescue the patient for infusion therapy, the infusion operation is very inconvenient.

Contents of the invention

The purpose of this utility model is to provide a multi-purpose disposable infusion device, which can input different medicinal liquids with one infusion device, and can prevent the contamination of the medicinal liquid and not increase the number of punctures of the patient's veins, especially when infusion is performed on the patient. When the treatment needs to temporarily increase the intravenous administration or rescue the patient, the transfusion operation is very convenient.

The purpose of this utility model is achieved in this way: a multi-purpose disposable infusion set, including a bottle stopper double-cavity puncture needle, a drip funnel and a venipuncture needle connected together through an infusion tube, and the drip funnel and the venipuncture needle are connected A regulator is installed on the infusion tube, an upper three-way pipe joint is installed on the infusion tube between the cork double-chamber puncture needle and the drip funnel, and a lower three-way pipe joint is connected to the infusion tube at the rear of the regulator. A filter is installed at the end of the infusion tube connected to the outlet of the through pipe joint, and a venipuncture needle is installed on the outlet of the filter through a connecting flexible pipe.

When using the utility model, when the branch pipe inlets of the upper three-way pipe joint and the lower three-way pipe joint are closed, it can be used as a general disposable infusion set. When the utility model is used to temporarily add medicine for infusion treatment to a patient, the branch pipe inlet of the upper three-way pipe joint can be opened, and the newly added medicine can be input for the patient through the infusion tube connected thereon through the infusion set. Especially when performing operations on patients, it is very convenient to inject anesthetics into the vein, which can prevent excessive or excessive input of anesthetics. When the utility model is used for the patient's infusion treatment to temporarily need to administer the drug to the vein, the branch pipe inlet of the lower three-way pipe joint can be opened, and the infusion tube connected thereon can be used to administer the drug to the patient's vein through the venipuncture needle. Therefore, when infusion therapy is given to the patient, different medicinal liquids can be input to the patient through an infusion set of the utility model, and the pollution of the medicinal liquid can be prevented and the number of puncture times of the patient's veins can not be increased. Especially when infusion therapy is performed for patients, when it is necessary to temporarily increase intravenous administration or rescue patients, the infusion operation is very convenient.
