17/709125

Inventors:

- Concord MA, US
Jennifer J. Davagian - Acton MA, US

International Classification:

A61M 31/00

Abstract:

A single-use suppository insertion device includes a barrel, a plunger configured to be movably coupled to the barrel, and a disabling feature of the barrel or the plunger. The disabling feature may be configured to be activated during operational motion of the plunger relative to the barrel, such as during insertion of or withdrawal away from a suppository. The device can include a structural element of the barrel or the plunger configured to engage with the disabling feature of the barrel or the plunger during insertion of or withdrawal away from the suppository to activate the disabling feature. The disabling feature may be implemented in a number of ways to ensure single-use operation of the single-use suppository insertion device.

Jennifer J. Davagian - Sudbury MA, US

International Classification:

A61M 31/00

Abstract:

Rectal suppositories are used to administer a predetermined drug dosage to treat a variety of diseases and symptoms in a variety of patient populations. Certain medical conditions, such as digestive disorders, may be more effectively treated when the suppository is placed in a particular location of the patient's anal canal or rectum. An apparatus for inserting a suppository can include an applicator having a barrel, such as a hollow cylindrical body, and a plunger, such as a substantially cylindrical elongated body. The apparatus can include features to ensure that beneficial gas flow paths associated with the plunger or the barrel are maintained or that the apparatus can accommodate suppositories of different sizes. Embodiments may include features to facilitate gripping and manipulation of the apparatus for use by patients with limited dexterity. These benefits may encourage patients to maintain a course of treatment, thereby potentially avoiding additional complications, hospitalization, and costs.
