Appl. No.:

17/771950

Inventors:

- Osaka-shi, Osaka, JP
David Michael Forman - Fountain Hills AZ, US

International Classification:

A61M 5/30
C06C 7/00

Abstract:

An accelerator module is connected to an initiator module and generates supersonic waves from subsonic waves generated by the initiator module. The supersonic waves deliver particles to cells in tissues. The accelerator module may include a knocking-detonation transition metal and a detonation material. An example of the knocking-detonation transition metal is copper (I) 5-nitrotetrazolate. Another example of the knocking-detonation transition metal is lead azide. An example of the detonation material is pentaerythritol tetranitrate (PETN).

A61M 5/14

Abstract:

This application relates to a wearable multi-shot injection patch. In one aspect, the patch includes a base that has a bottom surface and a top surface and is configured so that the bottom surface is disposed against a patient's skin. The patch may also include a first container that is supported by the base and accommodates a first drug, and a second container that is supported by the base and accommodates a second drug. The patch may further include a first pyrotechnic charge disposed between the top surface and the first container inside the base, and a second pyrotechnic charge disposed between the top surface and the second container inside the base. The patch may further include one or more electronic components configured to detonate the first pyrotechnic charge and the second pyrotechnic charge.
