Abstract

The object is to provide an ampoule usable as a syringe, and a syringe unit which are easy to handle, excellent in quantitative accuracy, and further more excellent in hygienic aspect. The above object is solved by an ampoule usable as a syringe comprising: a front edge portion (4) which is removed when the ampoule is used; an ampoule body (2) which can accommodate a drug solution (10); and a liquid infusing portion (3) connecting the front edge portion (4) and the ampoule body (2); the ampoule body (2) being able to place a movable stopper (5) in contact with an internal surface of the ampoule body (2), and being able to accommodate the drug solution (10) hermetically-sealed in the through-hole (6) between the movable stopper (5) and the sealing portion (4a).

Description

technical field [0001] The present invention relates to an ampoule usable as a syringe for injecting medicinal liquid into living bodies such as patients and animals. The invention also relates to a syringe unit with an ampoule usable as a syringe and an ampoule holder. Background technique [0002] Injections are usually given with a needle syringe. However, using a syringe needle can be frightening and painful for the patient taking the medicine. Especially when it comes to drug treatment or diagnosis for children, many children are afraid of syringe needles, which will hinder drug treatment and so on. Also, very careful handling of syringe needles after use by patients is required. If not handled properly, there will be a high risk of infecting other patients or medical staff. Therefore, used syringe needles are disposed of as medical waste. [0003] Therefore, needle-free syringes without needles have been developed, and in recent years have gradually replaced needl...
