Experimental animal nose administration device

Abstract

This utility model discloses a nasal drug delivery device for laboratory animals, including a syringe. An infusion tubing is fixedly connected to the dispensing end of the syringe. A dispensing tube is fixedly connected to one end of the infusion tubing. A sliding ring is slidably connected to the dispensing tube. An anti-dislodgement component is provided on the sliding ring. A fixing plate is fixedly connected to one side of the sliding ring. This utility model, by setting up a fixing block, magnet, connecting frame, belt, rotating rod, metal clamp, and actuating block, allows the belt to be placed over the animal's chin and head. Pulling one end of the belt tightens it, causing the metal clamp to engage in the corresponding slot. The belt is then secured to the animal's head. The universal metal tubing is then bent, causing the sliding ring to move via the fixing plate. The sliding ring moves the dispensing tube, inserting it into the animal's nasal cavity. This reduces the likelihood of the infusion tubing falling off due to head movement during nasal injection.
