The USPTO provides a Patent Public Search tool for searching patents and patent application publications. To identify the most relevant prior art for US patent 10814058, I will examine the "Cited By" and "Citations" sections of the patent document itself. [cite: US10814058B2]

Here's an analysis of the prior art cited in US patent 10814058:

Prior Art References (Citations by Examiner/Applicant):

  1. US1856811A

    • Full Citation: US1856811A, "Nasal irrigator" to Hooichi Sumida. [cite: US10814058B2]
    • Publication/Filing Date: Publication Date: 1932-05-03, Priority Date: 1931-07-11. [cite: US10814058B2]
    • Brief Description: This patent describes a nasal irrigator, which is a device for washing the nasal passages. [cite: US10814058B2]
    • Potentially Anticipated Claims: This likely anticipates aspects of the "spray part" and "nasal wash function" broadly, particularly the concept of introducing liquid into the nasal cavity. Specific claims like those detailing the atomization unit (claim 1) or the spaced-apart outlets (claim 1) would need further analysis for direct anticipation.

  2. JPS5836563A

    • Full Citation: JPS5836563A, "Ultrasonic inhalator" to ロヴエンタ−ヴエルケ・ゲゼルシヤフト・ミツト・ベシユレンクテル・ハフツング. [cite: US10814058B2]
    • Publication/Filing Date: Publication Date: 1983-03-03, Priority Date: 1981-06-06. [cite: US10814058B2]
    • Brief Description: This describes an ultrasonic inhalator, which implies a device for delivering atomized substances, likely for respiratory purposes. [cite: US10814058B2]
    • Potentially Anticipated Claims: This could be relevant to the "atomization unit" (claim 1) of US10814058, as it involves atomizing liquid. The specific mechanism of atomization would be key.

  3. US6328718B1

    • Full Citation: US6328718B1, "Snivel sucker" to Chien-Li Chen. [cite: US10814058B2]
    • Publication/Filing Date: Publication Date: 2001-12-11, Priority Date: 2000-04-29. [cite: US10814058B2]
    • Brief Description: This patent describes a device for sucking nasal mucus, a "snivel sucker." [cite: US10814058B2]
    • Potentially Anticipated Claims: This directly relates to the "suction part" (claim 1) and its function of inhaling gas and sucking nasal mucus. The detailed structure of the suction part, including the collection cavity and inhalation tubes (claim 2), would need to be compared against this reference.

  4. EP1180373A2 (and related EP1180373A3, US6520931B2)

    • Full Citation: EP1180373A2, "Medical instrument" to G-Intek Co., Ltd. [cite: US10814058B2]
    • Publication/Filing Date: Publication Date: 2002-02-20, Priority Date: 2000-08-17. [cite: US10814058B2]
    • Brief Description: This broadly describes a medical instrument. [cite: US10814058B2] Further investigation into the specifics of this "medical instrument" would be necessary to determine its relevance to US10814058, particularly if it combines aspiration and washing functions.
    • Potentially Anticipated Claims: Without a more specific description, it's difficult to pinpoint exact claims. If this "medical instrument" combines aspiration and irrigation, it could potentially anticipate the overall concept of a combined device, as in claim 1.

  5. US20030145849A1

    • Full Citation: US20030145849A1, "Agent delivery and aspiration device" to Darrel Drinan. [cite: US10814058B2]
    • Publication/Filing Date: Publication Date: 2003-08-07, Priority Date: 2002-02-04. [cite: US10814058B2]
    • Brief Description: This patent application describes a device that can both deliver an agent and perform aspiration. [cite: US10814058B2]
    • Potentially Anticipated Claims: This is highly relevant as it describes a device with both delivery (spray) and aspiration (suction) functions, similar to the core concept of claim 1 of US10814058. The specific arrangement of the delivery and aspiration parts, especially their spacing and independent operation, would be crucial for determining anticipation.

  6. WO2008058160A2 (and related WO2008058160A3, JP2010527636A)

    • Full Citation: WO2008058160A2, "Irrigation and aspiration device and method" to Aardvark Medical, Llc. [cite: US10814058B2]
    • Publication/Filing Date: Publication Date: 2008-05-15, Priority Date: 2006-11-06. [cite: US10814058B2]
    • Brief Description: This describes an irrigation and aspiration device and a method for using it. [cite: US10814058B2]
    • Potentially Anticipated Claims: Similar to US20030145849A1, this reference is highly relevant to claim 1 of US10814058 due to its combined irrigation (wash) and aspiration (suction) functions. The spatial relationship of the irrigation and aspiration components would be a key point of comparison.

  7. EP2005981A2 (and related EP2005981A3, US7862536B2)

    • Full Citation: EP2005981A2, "Combined nasal spray and aspirator device" to Avita Corporation. [cite: US10814058B2]
    • Publication/Filing Date: Publication Date: 2008-12-24, Priority Date: 2007-06-15. [cite: US10814058B2]
    • Brief Description: This patent describes a combined nasal spray and aspirator device. [cite: US10814058B2]
    • Potentially Anticipated Claims: This reference is particularly important because it is also assigned to Avita Corporation, the same assignee as US10814058B2. [cite: US10814058B2] It directly addresses a "combined nasal spray and aspirator device," making it highly relevant to claim 1. The key differentiator for US10814058, as stated in its abstract and claim 1, is the spaced-apart nature of the suction inlet and spray outlet to prevent interference and avoid replacing functional assemblies. Therefore, the specific arrangement of the spray and aspiration elements in EP2005981A2 would be critical for determining anticipation of claim 1.

  8. WO2010126586A1

    • Full Citation: WO2010126586A1, "Irrigation and aspiration devices and methods" to Aardvark Medical, Llc. [cite: US10814058B2]

    • Brief Description: This details irrigation and aspiration devices and methods. [cite: US10814058B2]
    • Potentially Anticipated Claims: Similar to WO2008058160A2, this reference from the same applicant would also be highly relevant to claim 1 due to its combined irrigation and aspiration functions.

  9. CN202289114U

    • Full Citation: CN202289114U, "Portable atomizer" to 邓以翔. [cite: US10814058B2]
    • Publication/Filing Date: Publication Date: 2012-07-04, Priority Date: 2011-10-19. [cite: US10814058B2]
    • Brief Description: This describes a portable atomizer. [cite: US10814058B2]
    • Potentially Anticipated Claims: This directly relates to the "atomization unit" (claim 1) and the "spray part" of US10814058. The specifics of the atomizer's construction and its integration into a portable device would be relevant to the detailed features of the spray part.

  10. US20160206835A1

    • Full Citation: US20160206835A1, "Nebulizing device and nebulizer" to Delta Electronics, Inc. [cite: US10814058B2]
    • Publication/Filing Date: Publication Date: 2016-07-21, Priority Date: 2013-09-13. [cite: US10814058B2]
    • Brief Description: This patent application describes a nebulizing device and a nebulizer. [cite: US10814058B2]
    • Potentially Anticipated Claims: This is relevant to the "atomization unit" (claim 1) and the broader concept of atomizing liquid for therapeutic purposes.

Key Observations for Anticipation under 35 U.S.C. § 102:

  • Several references (e.g., US20030145849A1, WO2008058160A2, EP2005981A2, WO2010126586A1) explicitly describe combined aspiration and irrigation/spray devices, which is the core inventive concept of US10814058's independent claim 1.
  • The novelty of US10814058 largely relies on the "spaced apart" arrangement of the suction inlet and spray outlet, and their ability to function "without interfering with each other" and "without replacing a functional assembly." [cite: US10814058B2] Therefore, a thorough comparison of the physical configuration and operational independence of the cited combined devices against these specific features of claim 1 would be crucial for a § 102 anticipation analysis.
  • The fact that EP2005981A2 is also assigned to Avita Corporation suggests it may be a predecessor patent. Examining the differences between EP2005981A2 and US10814058 would be especially important to understand the specific advancements claimed in US10814058.
