Publication number: 20210106767Abstract: Described herein is a needle protective cover having a cylindrical barrel, a funnel, and a support mechanism. The cylindrical barrel has a proximal end and a distal end and is operable to receive a hypodermic needle or hypodermic needle sheath. The funnel is at the proximal end of the cylindrical barrel. The support mechanism surrounds the cylindrical barrel and funnel, such that the support mechanism is operable to prevent the needle protective cover from rolling on a surface and increases a distance from the funnel to the surface. The support mechanism may be a triangular body and/or one or more fins.Type: ApplicationFiled: October 12, 2020Publication date: April 15, 2021Inventors: SHARON SABO, CIANAN SABO

Publication number: 20210106768Abstract: A syringe device includes a barrel and a compressible portion is connected to one end of the barrel. A positioning board is located between the barrel and the compressible portion. The positioning board has a hole defined therethrough. A seat is formed to the underside of the positioning board and has a recess and multiple guide grooves which communicate with the recess. A hold part is connected to the distal end of the compressible portion and has a penetrating face. Two flanges respectively extend diametrically from the hold part. A needle is connected to the positioning board and communicates with the recess. The tip of the needle is located within the compressible portion and beneath the penetrating face. By axially compressing the compressible portion and the barrel, the needle penetrates through the penetrating face and extends beyond the hole to eject medicine to the patient.Type: ApplicationFiled: October 15, 2019Publication date: April 15, 2021Inventor: Chung-Sing LIN

Publication number: 20210106769Abstract: An air removal device for an intravenous fluid system includes a housing with an inlet for fluid communication with a fluid source, a fluid outlet for fluid communication with a blood vessel of a patient, and an air outlet. The air removal device further includes a disrupting element disposed within the housing in a flow path between the inlet and the fluid outlet, and an air chamber in fluid communication with the air outlet. The disrupting element includes a protrusion extending across the flow path. The flow path includes a first cross-sectional flow area at the inlet, and a second cross-sectional flow area at the protrusion. The second cross-sectional flow area is smaller than the first cross-sectional flow area.Type: ApplicationFiled: December 20, 2020Publication date: April 15, 2021Inventors: Norton Herrick, David Saloff, Richard Green

Publication number: 20210106772Abstract: A handheld digital nebulizer device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The handheld digital nebulizer device includes a housing having an exhalation valve, a reservoir, an ejector mechanism, and at least one differential pressure sensor. The handheld digital nebulizer device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The handheld digital nebulizer device is then actuated to generate a plume of droplets having an average ejected particle diameter within the respirable size range, e.g, less than about 5-6 ?m, so as to target the pulmonary system of the user.Type: ApplicationFiled: April 2, 2019Publication date: April 15, 2021Applicant: PNEUMA RESPIRATORY, INC.Inventors: John H. Hebrank, Charles Eric Hunter
