About

About The Operative Sentence

This domain, and the company that used to have it.

This site is published at biodrainmedical.com. The registration under which it is published was created on 6 August 2026, from the public drop pool — a registry creation date anyone can check in WHOIS. Whatever registration preceded it was not ours and had ended. We bought a lapsed domain name. We did not buy, inherit or continue any business.

From 2007 until about 2013, this domain served the website of BioDrain Medical, Inc., a publicly traded Minnesota medical device company whose only product was the STREAMWAY automated surgical fluid disposal system, cleared by the FDA on 1 April 2009 under 510(k) K090759. No company operates under the name BioDrain Medical today. That company renamed itself Skyline Medical Inc. on 6 August 2013, then Precision Therapeutics Inc. on 1 February 2018, then Predictive Oncology Inc. in June 2019, and is today Axe Compute Inc. (Nasdaq: AGPU), a Pittsburgh company in GPU compute and digital-asset treasury with no medical device business of any kind. It is the same legal registrant throughout — SEC CIK 0001446159 — renamed four times, not a chain of acquisitions. The STREAMWAY product line was sold outright to DeRoyal Industries, Inc. on 14 March 2025. DeRoyal owns and markets it today, and that is where anyone looking for the system will find it. If you are looking for the former company’s filings, they are on SEC EDGAR under CIK 0001446159.

The Operative Sentence is not BioDrain Medical, is not its successor, and has no affiliation with, endorsement from, agency for, or connection to Axe Compute Inc., DeRoyal Industries, Inc., or any other manufacturer, distributor or waste contractor. We do not manufacture, sell, distribute, service, install, specify, endorse or recommend any medical device. We publish no investor information and nothing here is a statement by or about any company’s securities. STREAMWAY is a registered trademark of its owner and is used here only to refer to the product by its name.

We are telling you the rest of it because you can find it yourself in the Internet Archive in about ninety seconds, and a publication whose whole method is showing you the source has no business being coy about its own. After the company left, this domain ran consumer-health affiliate pages from about 2015 to 2020. In October 2025 it served a cloaked Chinese-language sports-betting site under a randomised directory path. None of that was us, none of it is recoverable here, and every one of those paths returns 404 by deliberate configuration. The whole history, with dates and sources, is written down in the Domain Record.

Why publish here

Because the subject this domain was known for no longer has a publication. Outpatient Surgery Magazine ran a fluid-waste feature almost every year from 2004 to 2021 and was discontinued on 1 November 2025; its dated article archive is now almost entirely unreachable. What replaced it in search results is written mostly by companies that are paid by the pound to remove the waste stream they are describing. We are not neutral about that gap — we think it is worth filling — but we are clear that inheriting a domain is not inheriting authority. Nothing on this site asks you to trust us. It asks you to check the citation.

Who publishes this

Nobody on this masthead is a clinician. No one here has worked in an operating room, used a fluid-management system, or handled regulated medical waste. What we do is read documents: the Code of Federal Regulations, OSHA letters of interpretation, state administrative codes, municipal sewer-use ordinances, FDA clearance records, and the peer-reviewed literature. Every clinical, regulatory or operational claim on this site is a claim about what those documents say, attributed to a specific document, with the date we retrieved it. Where we could not obtain a document, we say that instead of paraphrasing someone who summarised it.

The Operative Sentence is published by Zane Hitchcox, an independent publisher, as a sole proprietorship. He is the sole editor and the sole author of everything here. There is no editorial team, no advisory board, no panel of reviewers, and no contributor whose name is not on the page. Every page here carries the line Not clinically reviewed, printed rather than omitted, because the alternative is inventing a reviewer. If a credentialed external reviewer is ever retained, that person will appear by name, with a credential, an affiliation and the date of the review, or the field will stay exactly as it launched.

Write to editor@biodrainmedical.com about anything on the site, and to corrections@biodrainmedical.com about anything that is wrong on it. Both are read by the same person, who answers them. What each address is for, and what we cannot help with, is set out at Contact.

What we cover

One subject, narrowly: the documents that decide what happens to blood, body fluids and the waste stream around an operating room, and the figures people cite when they argue about it. In practice that means seven kinds of source, and the work is to retrieve each one in full, print the sentence that does the work, and record the date we retrieved it.

• The federal bloodborne pathogens standard, in its codified text — what it requires, and the things it is widely said to require and does not contain.
• OSHA letters of interpretation, read whole, including the ones whose commonly cited date is the slug in their URL rather than the date on the letter.
• State medical-waste rules on liquid blood to the sanitary sewer, quoted from each state’s own administrative code, with the states we have not read published as rows rather than omitted.
• Sewer-use ordinances of large publicly owned treatment works, which bind independently of any state rule and which nobody assembles.
• State surgical-smoke statutes, by instrument, bill number, chapter or public-act number, signing date, effective date, and what is actually obligated.
• Federal guidance and the peer-reviewed literature on operating-room blood exposure, fluid volumes per procedure, and the composition of regulated waste.
• The provenance of the figures themselves — where a number in circulation came from, hop by hop, with each document’s HTTP status and the date we fetched it.

The three registers and the claims ledger are maintained tables rather than articles, and they are the part of this site most likely to be useful more than once. Everything any page cites is indexed at Documents cited.

What we do not cover

• No advice. Nothing here is legal advice, medical advice, or a substitute for your facility’s exposure control plan, your state’s rules or your sewer authority’s ordinance. We describe what published documents say; the decision is not ours and we are not in a position to make it.
• No products. No product recommendation, no ranking, no named-brand comparison of fluid-management systems, canisters, solidifiers or liners, and no review of any device. A manufacturer is named only where the identity of the party is itself the fact being reported.
• No procedure. No how-to, no troubleshooting instruction, no step-by-step, no protocol presented as ours.
• No experience. No first-person clinical account of any kind, because there is none to give.
• No company. No investor information, no securities statement, no company news, and nothing about the former registrant of this domain beyond what is needed to say plainly that we are not it.
• Nothing we cannot quote. Several of the standards that govern this subject — the FGI Guidelines, NFPA 99, the International Plumbing Code, and the professional-association position documents — are copyrighted and sold by their publishers. We can cite what they require; we cannot print their operative text. An article whose promise is that it prints the sentence cannot be built on a document it may not print, so those topics wait until we can source them properly rather than shipping a paraphrase.

How a topic is chosen, how a claim is traced, and where the whole method could be wrong is set out at Method. The seven editorial commitments, the certainty ladder, the closed status vocabularies and the correction policy are at Editorial standards.

Who pays for this

The publisher does, out of pocket. There is no advertising, no sponsorship, no affiliate link, no paid placement, no guest post, no link sale, no sponsored content and no paywall on this site, and no manufacturer, distributor, waste contractor or trade body sees a page before it is published. There is no commercial relationship of any kind to disclose, and if one ever exists it will be named here with its mechanism and logged as a dated entry in the change log rather than quietly added. The full statement, including what we would and would not accept, is at Independence and funding.

We collect nothing about you. The site sets no cookies, loads no third-party script, font or embed, and makes no request to any server but its own; what the web server logs, and for how long, is at Privacy.

How to hold us to it

Every article, every register and every maintained index carries the date it was published, the date it was last reviewed against its sources, and the date the next review is due. The short standing pages that describe the publication itself — this one, Contact, Corrections, Change log, How to cite and Privacy — do not carry that block; every substantive change to them is dated at Change log instead. Corrections are dated, permanent and describe the error rather than hiding it; they appear at Corrections and at the top of the corrected page, and the index launched empty and dated rather than populated with anything invented. Every substantive revision is logged at Change log. Our own prose, tables and diagrams are reusable under CC BY 4.0 on the terms at How to cite and reuse.

If something here is wrong, send it to corrections@biodrainmedical.com with the page title and the date printed on it. We aim to answer within five working days and to publish a documented correction within seven, whether or not the person who found it wants the credit.
