Abstract

The invention belongs to the field of infusion devices and particularly relates to a disposable precise filtering infusion device with a needle. In order to solve the problems that added liquid medicine is likely to be mixed nonuniformly and insoluble particles in the liquid medicine cannot be filtered since existing infusion devices are not provided with corresponding mixing devices, according tothe following scheme, the infusion device with the needle comprises a fixing base, a mounting cavity is formed in the fixing base, and a first infusion tube and a second infusion tube are fixedly mounted on the inner walls of the top and bottom of the mounting cavity respectively. According to the infusion device with the needle, liquid medicine is pushed into a connecting chamber to impact blades, then the liquid medicine can be pushed into a mounting pipe to be mixed and stirred with other liquid medicine in the mounting pipe, insoluble particles in the mixed liquid medicine can be filteredby a medicine film so that the insoluble particles can be prevented from entering the body of a patient, and therefore physical damage to the patient can be avoided; in addition, when medicine is added, the added medicine can be fully stirred with liquid medicine in an infusion bottle.

Description

technical field [0001] The invention relates to the technical field of infusion sets, in particular to a disposable precision filter infusion set with a needle. Background technique [0002] Intravenous infusion is an important means of clinical routine treatment, infusion requires the use of infusion set; infusion set is a disposable medical consumables mainly used for intravenous infusion, after aseptic treatment; the working principle of infusion set is that under the action of gravity, the bottle The liquid in the bottle flows into the Murphy's dropper along the thinner infusion hose. When the water column pressure of the Murphy's dropper is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose. [0003] Now when infusion is performed on patients, it often occurs during the infusion process that the step of adding medicine is required, but the existing way of adding medicine generally only uses a syringe to push the medicine liquid...
