Abstract: A protective case to be worn by an individual for carrying a medical device that may be required in case of allergic or asthmatic reactions or diabetic reactions. The case includes a rigid receptacle to protect the medical device. The case can be worn on a person's belt or it may be permanently fixed to a belt or a band that can be worn around the waist, an arm or a leg. For a standard syringe, the receptacle comprises an elongated, rigid cylindrical tube which fits closely about the syringe. The receptacle further includes an open end that is covered by a cap that can be readily removed to provide easy access to the syringe inside the tube and which protects the syringe from contamination. The case is unobtrusive in appearance and does not hamper the individual's movements thus allowance it to be worn at all times.
