Syringe. Gloved hand of a doctor gently squeezing a syringe to expel air from its contents. This is done before giving an injection to prevent bubbles of air being introduced into the patient's bloodstream,which could cause an arterial blockage,or embolism. The barrel of the syringe is calibrated in millilitres,allowing accurate doses to be given. Syringes are often disposable,coming in sterile sealed packs. Rubber gloves help maintain a sterile environment | |
