Safe and convenient filtering and dosing infusion device

Abstract

The invention discloses a safe and convenient filtering and dosing infusion device. The safe and convenient filtering and dosing infusion device mainly includes a first dosing bag, a second dosing bag, a liquid mixing bag, an infusion tube and a syringe needle structure, wherein the upper and lower ends of the first dosing bag are respectively connected with a first liquid inlet tube and a first liquid outlet tube; the upper and lower ends of the second dosing bag are respectively connected with a second liquid inlet tube and a second liquid outlet tube; the first liquid outlet tube and the second liquid outlet tube are each provided with a liquid outlet tube switch; the lower end of the first liquid outlet tube intersects with the lower end of the second liquid outlet tube, and is connected to an liquid inlet of the liquid mixing bag; an liquid outlet of the liquid mixing bag is connected to the infusion tube; the tail end of the infusion tube is the syringe needle structure; the syringe needle structure includes a syringe needle, a syringe needle protective cap sleeving the outer side of the syringe needle, and a connecting piece which fixedly connects the syringe needle protective cap and the infusion tube; and on the infusion tube, a liquid medicine filter is arranged above the syringe needle structure within a small distance. The safe and convenient filtering and dosing infusion device is accurate and convenient for dosing, and can precisely filter the liquid medicine, and the syringe needle is not exposed after completion of infusion, thus causing no pollution and damage.

Description

technical field [0001] The invention relates to a safe and convenient filtering and dispensing infusion device, which belongs to the field of medical supplies. Background technique [0002] The infusion set is a disposable medical device with a large amount of use and is closely related to our daily life. Sometimes the infusion needs to mix different medicines to the patient. However, some medicines cannot be mixed together for a long time and can only be used in the infusion It is cumbersome to mix the medicine before infusion, which is not conducive to emergency rescue. [0003] The invention with the application number of 201620402354.3 discloses an infusion set, which includes: an upper infusion hose, a lower infusion hose, and a drip pot whose inlet and outlet are connected to the upper infusion hose and the lower infusion hose respectively . The liquid medicine flow rate regulator arranged on the lower infusion hose, in addition, it also includes: a liquid dispensing ...
