Resumen de: WO2024229565A1
The present invention introduces a new concept in additive manufacturing (AM) by printing remotely without direct access to printing locations. Common energy sources in AM, heat and light, have small penetration into an optically opaque medium. However, the present invention introduces a deep penetration access to the printing medium using acoustic waves. Acoustic wave patterns create chemically active regions in which the printing material is solidified. The printing material may be a heat curing polymer or polymer composite. This concept introduces a new paradigm in non-invasive/minimally invasive bio-printing inside body, without open surgery, which is proved experimentally in this patent. In addition, a new concept of printing underneath solid and opaque shells with industrial application especially in aerospace is introduced, generated individually with dimensions smaller than those currently achieved;
Resumen de: WO2024233888A1
A dose divider for releasable attachment to a plunger rod of a syringe comprises first and second arms. A front portion of the first arm and the front portion of the second arm form a channel therebetween for receiving the plunger rod. A resilient hinge pivotably couples the first arm and the second arm such that the dose divider is reversibly movable between first and second configurations. When the dose divider is in the second configuration, the dose divider is configured to receive the plunger rod in the channel through an opening formed between the front portions of the first and second arms. The channel has a shape configured to receive a specific outer shape of the plunger rod. The front portions of the first and second arms are closer when the dose divider is in the first configuration than when the dose divider is in the second configuration.
