Publication number: 20240042444Abstract: A microfluidic device with a microfluidic circuit including an array of fluidly coupled microchambers. Each microchamber includes a reaction chamber and an associated vent chamber. The microfluidic circuit may be arranged so that a fluid sample introduced to microfluidic device flows into the reaction chamber and air or other gas present in the reaction chamber is vented from the microchamber through the vent chamber. The microchamber may be configured to allow only the flow of air into the vent chamber from the reaction chamber until the air has been displaced from the reaction chamber by the fluid sample and/or a predefined volume of the fluid sample has been received in the reaction chamber. The microchamber may be further configured to release the fluid sample to thereafter flow from the reaction chamber into the vent chamber.Type: ApplicationFiled: October 13, 2023Publication date: February 8, 2024Inventors: Kabir James YAMANA, Sean YAMANA-HAYES

Publication number: 20150359203Abstract: A fluid delivery system implemented within an in ovo injection apparatus is disclosed, wherein the fluid delivery system includes a plurality of membrane valves. In particular, the fluid delivery system includes a diaphragm valve that is used to meter out a precise volume of a treatment substance liquid. Further, the diaphragm valve includes certain standoff features on the surface thereof for reducing or entirely preventing the adhesion of the diaphragm to adjacent surfaces when left idle for an extended period of time, as well as an arrangement of fluid channels in the surface thereof for reducing or entirely preventing the trapping of liquid between the diaphragm and adjacent surfaces. The fluid delivery system includes features contributing to optimized flow characteristics.Type: ApplicationFiled: April 27, 2015Publication date: December 17, 2015Inventors: Thomas Matthew Hessler, Kabir James Yamana

Publication number: 20150313636Abstract: A perineal protection device for use during childbirth comprises one or more pads configured to be placed on the perineum and having a varying level of resistance to stretch along the anterior-posterior axis between the vaginal opening and the anus. The device further includes attachment means in the form of adhesives, hooks, sutures, or other suitable means, for adhering the pad to the skin during childbirth, with the result that stress on the perineum is reduced during childbirth, thus reducing tearing during childbirth. The resistance to stretch is relatively lower near the vaginal opening, and relatively greater near the anus. The increase can be linear or nonlinear. The pad can be formed monolithically or in multiple portions. The resistance to stretch can be varied by varying the modulus of elasticity, varying cross-sectional area, or other suitable mechanical or materials-based techniques.Type: ApplicationFiled: November 20, 2013Publication date: November 5, 2015Inventors: Daniel Z. SHEN, Kabir James YAMANA

Patent number: 9163277Abstract: Microfluidic devices of the present disclosure relate to quick and inexpensive microfluidic manipulation/handling. A number of channels may be provided for supply of fluid ingredients to a number of cavities. A separating material may provide fluid separation between a number of cavities, such as corresponding cavities of a reaction chamber. Once the cavities are supplied with fluid ingredient, channels connecting the cavities may be sealed off; that is, the cavities may be subject to fluid isolation. In some embodiments, a sealing material may be compressed so as to deform into the channels obstructing fluid flow. The separating material may be manipulated so that the initial fluid separation between cavities is removed. Removal of this fluid separation subsequently permits mixing of fluid ingredient(s) contained within previously separated cavities. In some embodiments, the fluid separation may be removed by heating or dissolving portions of the separating material.Type: GrantFiled: March 14, 2013Date of Patent: October 20, 2015Assignee: Formulatrix, Inc.Inventors: Kabir James Yamana, Sean Yamana-Hayes

Patent number: 9039993Abstract: Microfluidic devices of the present disclosure relate to quick and inexpensive microfluidic manipulation/handling. A number of channels may be supplied with fluid ingredient(s). In some embodiments, a number of protrusions as well as a sealing material may be disposed adjacent to the channels. When the channels are supplied with fluid ingredient(s), the channels may be partitioned into a number of separate cavities that are fluidly isolated from one another. For instance, a sealing material may be compressed so as to deform into the channels, obstructing fluid flow. In some embodiments, the channels supply fluid ingredients to a number of pre-formed cavities. Once the cavities are supplied with fluid ingredient, channels connecting the cavities may be sealed off; that is, the cavities may be subject to fluid isolation. When appropriate, contents within reaction chambers may be subject to further processing (e.g., thermal cycling, various analyses).Type: GrantFiled: March 14, 2013Date of Patent: May 26, 2015Assignee: Formulatrix, Inc.Inventors: Kabir James Yamana, Sean Yamana-Hayes
