Abstract

Abstract A central housing includes a coaxially reciprocatable screw member operative through a selectively actuated drive motor to effect reciprocation of the screw within the housing. The screw member includes a piston mounted at a forward distal end thereof mounting a flexible bag therewithin, wherein the bag directs suction from a forwardly coaxially mounted nozzle into the bag.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 305 words
An infant nasal suction apparatus, comprising: an elongate cylindrical housing, the cylindrical housing including a housing rear terminal end and a housing forward terminal end, the housing rear terminal end including a first end cap mounted releasably thereto, and the housing forward terminal end including a housing second end cap removably mounted thereto, the central housing including a central housing web, the central housing web fixedly mounted within the housing adjacent the housing rear terminal end, with the central housing including a housing axis, with the housing web oriented orthogonally relative to the housing axis, and a gear shaft rod reciprocatably and coaxially mounted within the central housing, and coaxially directed through the central housing web within a gear shaft rod guide bore coaxially directed through the housing web, and the gear shaft rod including a piston member mounted at a forward terminal end of the gear shaft rod orthogonally oriented relative to the housing axis, and drive means for effecting reciprocation of the gear shaft rod for providing a suction between the piston and the second end cap, the second end cap including a nozzle coaxially mounted thereto for directing fluid through the nozzle into the housing between the second end cap and the piston, and wherein the drive means includes a drive motor fixedly mounted within the first end cap, the drive motor including a reversing switch projecting through a side wall of the first end cap, and the drive means further including an on/off switch mounted within the end cap spaced from the drive motor, and a battery, and the drive motor including an output drive shaft, the output drive shaft rotatably mounted within a drive shaft bore formed within the central housing web, and a drive shaft gear mounted to the drive shaft to effect reciprocation of the gear shaft rod.
Claim 2
Dependent Claim 305 words
An infant nasal suction apparatus, comprising: an elongate cylindrical housing, the cylindrical housing including a housing rear terminal end and a housing forward terminal end, the housing rear terminal end including a first end cap mounted releasably thereto, and the housing forward terminal end including a housing second end cap removably mounted thereto, the central housing including a central housing web, the central housing web fixedly mounted within the housing adjacent the housing rear terminal end, with the central housing including a housing axis, with the housing web oriented orthogonally relative to the housing axis, and a gear shaft rod reciprocatably and coaxially mounted within the central housing, and coaxially directed through the central housing web within a gear shaft rod guide bore coaxially directed through the housing web, and the gear shaft rod including a piston member mounted at a forward terminal end of the gear shaft rod orthogonally oriented relative to the housing axis, and drive means for effecting reciprocation of the gear shaft rod for providing a suction between the piston and the second end cap, the second end cap including a nozzle coaxially mounted thereto for directing fluid through the nozzle into the housing between the second end cap and the piston, and wherein the drive means includes a drive motor fixedly mounted within the first end cap, the drive motor including a reversing switch projecting through a side wall of the first end cap, and the drive means further including an on/off switch mounted within the end cap spaced from the drive motor, and a battery, and the drive motor including an output drive shaft, the output drive shaft rotatably mounted within a drive shaft bore formed within the central housing web, and a drive shaft gear mounted to the drive shaft to effect reciprocation of the gear shaft rod.
Claim 3
Dependent Claim 71 words
An apparatus as set forth in claim 1 wherein the first end cap includes a rearwardly projecting cylindrical end cap coaxially aligned with the central housing, and including a guide bushing therewith, the guide bushing including an end cap cylindrical cavity defined by a predetermined diameter, the shaft rod equal to the predetermined diameter complimentarily received within the cylindrical cavity, wherein the cylindrical cavity is coaxially aligned with the central housing.
Claim 4
Dependent Claim 123 words
An apparatus as set forth in claim 2 including a pleated bag member mounted between the piston and the second end cap, the bag member including a plurality of annular pleats, and at least one of said annular pleats including an annular bacterial paste ring coated to an interior surface of the at least one of said pleats, and the annular bacterial paste ring covered by at least one of said pleats when in a contracted position when the piston is positioned adjacent the second end cap, and the annular bacterial paste ring exposed when the bag member is an extended position when the piston is positioned in a further position with the gear shaft rod positioned within the end cap cylindrical cavity.
