Description

Technical Field

[0002] To prevent debris such as rubber stopper fragments from entering the infusion bag and causing misunderstandings for patients, existing parenteral nutrition infusion bags typically have filters installed inside the tubing to remove rubber stopper fragments. However, this does not prevent the rubber stopper fragments from clogging the filter and affecting the flow rate of the medication. For example, the improved disposable parenteral nutrition infusion bag disclosed in Chinese patent application number CN201720437694.4 has a nutrient solution infusion tube consisting of a main line and three branch lines formed in the middle. The ends of the three branch lines are connected to nutrient solution bottles. A precision filter is installed at the main line at the lower end of the three branch lines to facilitate the mixing of various parenteral nutrition solutions and to filter out some impurities, thus avoiding misunderstandings for patients. However, this does not prevent rubber stopper fragments from clogging the filter and affecting the flow rate of the medication. Utility Model Content

A filter screen is placed inside the connecting tube for ease of manufacturing. The filter screens inside the connecting tubes between the branch tube and the infusion tube, and between the infusion tube and the spiral tube, are respectively designed as conical and inclined shapes. A debris collection groove is provided on the side of the connecting tube, allowing rubber stopper debris to be blocked by the filter plate and fall into the debris collection groove due to gravity, preventing the rubber stopper debris from clogging the filter plate, reducing the drug flow rate, and preventing rubber stopper debris from flowing into the infusion bag. This design avoids misunderstandings about medical care and reduces doctor-patient disputes. Multiple nutrient solutions are mixed and injected into the infusion tube via three separate tubes. A spiral blade inside the infusion tube stirs and mixes any unmixed medications. Spiral grooves on the inner wall of the infusion tube cause the medication to flow in a spiral shape into the spiral tube. A spiral frame maintains the shape of the spiral tube. The gravitational potential energy of the medication accelerates its flow within the spiral tube. The centrifugal force of the medication within the spiral tube, combined with the spiral flow of the medication, increases the uniformity of the mixture. A filter screen inside the connecting tube prevents impurities from entering the infusion bag.
