  • Publication number: 20240352947
    Abstract: An air blower has an inlet muffler and an outlet muffler to reduce the noise of the air blower during operation. Each of the mufflers may have two sections. One section is configured to attenuate high frequency noise and the other section is configured to attenuate lower frequency noise. A tubular internal wall in each of the mufflers defines the through passage for each of the mufflers. A noise absorbent material may be fitted about the tubular wall within each muffler. A plurality of holes are formed along the tubular wall of each through passage to expose the through passage to the noise absorbent material. A heater plenum may be interposed between the blower plenum and the outlet muffler to heat the air from the blower plenum. A filter at the input muffler filters the air sucked into the air blower.

  • Patent number: 12053322
    Abstract: An echogenic needle may have at least one V-shaped spiral groove formed at its distal portion adjacent to its patient end. The walls of the groove are orthogonal to each other. The groove is titled at a given angle from a neutral position toward the proximal end of the needle so that when the needle is inserted into the patient at an insertion angle under ultrasound imaging, the ultrasound wave emitted from the ultrasound transducer is reflected in a substantially reverse direction back to the transducer by at least one wall of the spiral groove. A pair of crisscrossing grooves may be spirally wound about the distal portion of the needle with each groove being tilted to the given angle to enhance echogeneity. The echogeneity of the needle may also be enhanced by increasing the pitch density of each groove while maintaining the crisscrossing groves at their neutral position.
