20210338209 | HIGH QUALITY HIGH FRAME RATE ULTRASOUND IMAGING WITH DIVERGING TRANSMIT BEAMS - An ultrasound system produces high quality images at a high framerate of display. A plane or volume to be imaged is scanned by different diverging transmit beams to acquire a series of different sub-frames, the number of sub-frame acquisitions comprising a total number of transmit beams which would produce a high quality image. The echoes received in response to the transmit beams of a sub-frame are coherently combined with the echoes received in other sub-frames. Each time the echoes of a new sub-frame have been coherently combined with the echoes of all other different sub-frames, a full image is produced. After a complete series of sub-frames has been received and the echoes combined, another series of sub-frame acquisition is commenced and a new series of sub-frames acquired. As each new sub-frame is acquired, it is coherently combined with all the other different and most recently acquired sub-frames. This technique produces a new image at the sub-frame scanning rate, rather than awaiting a completely new series of sub-frames before forming a new image. | 2021-11-04 |
20210338210 | URINE SAMPLING VESSEL - A biological fluid sampling vessel may include a container portion having an opening and an interior for housing a urine sample therein. The vessel may further include a sampling portion that removably engages the container portion to close off the interior. The sampling portion may include a sampling wand configured for obtaining a sample. | 2021-11-04 |
20210338211 | OCULAR INSERTS WITH ANALYTE CAPTURE AND RELEASE AGENTS - An ocular device for insertion into the eye (for example, into a lacrimal punctum or a conjunctival sac) are described herein. The ocular device may continuously capture specific analytes from tear fluid. Several embodiments of the ocular device may have one or more open channels and pores that enable tears to drain naturally through while capturing specific analytes. A mechanism of detecting analytes in bodily fluids using materials comprised of DNAzymes and/or aptamers are described herein. Aptamers are oligonucleotide or peptide molecules that bind to a specific target molecule. DNAzymes are designed to catalyze a number of biological reactions (i.e., RNA cleavage, DNA cleavage, ligation, or phosphorylation reactions). A number of ways an ocular insert may capture analytes in tear fluid in vivo for subsequent in vitro analysis are described herein. Additionally, a specific mechanism for colorimetric detection of analytes using aptamer- and/or DNAzyme-crosslinked hydrogels are described herein. | 2021-11-04 |
20210338212 | Device for Detection and Treatment of Viruses - Viruses, including corona viruses such as COVID-19, are often present in the mouth or nose of a person before they infect the body. The disclosed electrochemical device destroys or denatures viruses in the mouth or nose rendering the viruses ineffective to cause infection by applying a low voltage potential to the mucus. The device can being configured to detect viruses through chronoamperomatry. | 2021-11-04 |
20210338213 | BIOPSY DEVICE HAVING A HYDRAULIC DRIVE ASSEMBLY - A biopsy device includes a hydraulic drive assembly, a drive mechanism, and a biopsy member. The hydraulic drive assembly includes a chamber housing, a drive piston, a driven piston, a cavity in the chamber housing between the drive piston and the driven piston, and a hydraulic fluid that fills the cavity and hydraulically connects the drive piston to the driven piston. The chamber housing defines a proximal chamber, a distal chamber, and a transition chamber, collectively forming a continuous passage. The drive mechanism includes a motor, a drive gear attached to the motor, a driven gear engaged with the drive gear, and a drive link member coupling the driven gear to the drive piston. The drive mechanism is drivably connected to the drive piston to move the drive piston in the proximal chamber. The driven piston moves in the distal chamber. The biopsy member is connected to the driven piston. | 2021-11-04 |
20210338214 | A DEVICE FOR ENDOSCOPIC EXAMINATION CUM SAMPLE COLLECTION AND METHOD THEREOF - The present invention provides an endoscopic device for examination cum sample collection of an orifice of a user's body. In particular, the device is useful for vaginal and cervical examination. The device comprises a camera attached on the probe along with a radial luminous system and cytobrush for sample collection attached within the probe. A latex balloon and air flow directly through port are provided to inflate the vaginal cavity. The invention also provides the method for sample collection and supervision through controlled camera. | 2021-11-04 |
