Publication number: 20230226553Abstract: Cartridges and related systems and methods are disclosed. In accordance with an implementation, a method includes securing a sample container in a sample container receptacle of a cartridge using a sample container lock and coupling the cartridge to a cartridge receptacle of a system. The method also includes depositing a sample from the sample container within a sample well of the cartridge and determining a presence of a target molecule within the sample using the system. In response to the target molecule being present within the sample, the method includes releasing the sample container lock of the cartridge to allow the sample container to be removed from the sample container receptacle and for the cartridge to remain coupled to the system.Type: ApplicationFiled: August 31, 2021Publication date: July 20, 2023Inventors: Steven Barnard, Craig Ciesla, Paul Crivelli, Justin Davidson, Darren Segale

Publication number: 20220168737Abstract: Well assemblies and related methods are disclosed. In accordance with an implementation, an apparatus includes a liquid reservoir containing a liquid and a well assembly including a body, a hydrophobic venting membrane, and a cover. The body defines a well and has an opening and a port. The port is couplable to the liquid reservoir. The hydrophobic venting membrane is coupled to the body and covers the opening and cover covers the hydrophobic venting membrane. As the liquid is flowed into the well via the port, the hydrophobic venting membrane vents gas contained within the well.Type: ApplicationFiled: December 1, 2021Publication date: June 2, 2022Inventors: Cameron Mar, Payam Taheri, Cyril Delattre, Paul Crivelli, Wesley Cox-Muranami, Zhenning Cao, Travis Beckman, Justin Davidson

Publication number: 20140187987Abstract: A sphygmomanometer with a cuff for use on a patient wrist, upper or lower arm incorporates an inflatable bladder and a support structure. The cuff is subdivided into two sections. The first section holds the bladder against an arterial side of the limb, while the second section abuts a non-arterial side of the limb and is mechanically coupled to the support structure. When the cuff is attached to the patient limb, the bladder is positioned to avoid receiving a gravitational force caused by the weight of the limb. Rather, the gravitational force is absorbed by the support structure in an interior area of the cuff removed from the bladder.Type: ApplicationFiled: December 28, 2012Publication date: July 3, 2014Applicant: KAZ USA, INCInventors: Jacob Fraden, Justin Davidson, William Ewing
