Two parts drip chamber of infusion set and method of manufacturing two parts drip chamber

A drip chamber for an infusion set to administer delivery of intravenous fluid to a patient, wherein the drip chamber comprises:

• an upper body which is transparent and made up of a material selected from a group of thermoplastic polymers containing one or more of Acrylonitrile Butadiene Styrene (ABS) or Polycarbonate (PC), wherein:
• a proximal end of the upper body includes a piercing means extending radially outwards for deflating a container or bottle of intravenous fluid, wherein the piercing means is provided with hole for fluid to flow into the drip chamber;
• an air valve with a cap is situated at a middle or lower middle portion of the upper body, wherein the air valve has a filter and used for management of air in the drip chamber;
• a drop former is situated in the upper body of an interior of the drip chamber;
• and
• a distal end region of the upper body is preformed in a circular ring shape;
• and
• a lower body which is transparent and made up of a material selected from a group of plastic containing one or more of Thermoplastic Elastomer (TPE), Thermoplastic Polyurethane (TPU) or Poly Vinyl Chloride (PVC), wherein:
• a distal end of the lower body is configured to connect to an intravenous infusion tube, wherein the distal end (140b) of a the lower body includes a fluid flow regulating element before a connection point with the intravenous infusion tube;
• and
• a proximal end region of the lower body is preformed in a circular ring shape;
• wherein the preformed circular ring shape region at the distal end of the upper body (120) and the preformed circular ring shape region at the proximal end of the lower body are securely coupled in a leak-proof manner by an adhesive material selected from one or more of Cyclohexanone or Cyclohexanone with Poly Vinyl Chloride (PVC) resins.
