Talk:Jet injector

Image

Added a PD photo, would be nice to have a diagram or something too. Not to mention a bigger article :) - FrancisTyers 00:57, 7 December 2005 (UTC)

There's also something like this around, which someone with knowledge should probably take a look at. Perhaps in conjunction with the hypospray also? --Ouro 12:59, 23 October 2006 (UTC)

Cleanup

I tagged this article for cleanup, as the information is confusing and the article is formatted terribly. It's not very clear on the subject matter. --Cs92 10:14, 12 November 2006.

History and Pain

Should this page include the 1947 reference to "Hypospray" in the radio dramatization of "The Shadow"? It is the same basis for the technology of the Jet Injector and pre-dates the "Star Trek" usage of the word.

Also, should anything be mentioned about the pain level of using the Jet Injector? Is it painless or is there pain? —Preceding unsigned comment added by 206.136.32.234 (talk) 18:39, 21 September 2007 (UTC)

• Re the 1947 use of "hypospray": please insert it. Anthony Appleyard 21:26, 21 September 2007 (UTC)

• Re. "1960: Aaron Ismach invented and patented the Jet Injector medical device which was used for quick mass vaccination for smallpox and other diseases." There is an earlier patent 2821981 issued 1958 for a "MULTI-SHOT INOCULANT INJECTOR INSTRUMENT WITH ADJUSTABLE EJECTION PRESSURE CONTROL" invented by Frank A. Ziherl , viewable on Google patents I actually own one of these units called a "Press-O-Jet" and made by Z&W manufacturing, Wickliffe, Ohio however I don't know if this is the first such instrument invented only that it's earlier than the one in the article. 86.18.253.62 (talk) 21:37, 29 November 2011 (UTC) Martin King

Physiological Impact

This article is in dire need of additional information about the actual injection process from a physiological standpoint. There is only one sentence referencing the process ("...uses a high-pressure narrow jet of the injection liquid instead of a hypodermic needle to penetrate the epidermis"), while most of the article deals with the technological design/design history of the injector. How does the liquid penetrate the epidermis (is there a hole afterward)? Is the process painful or painless? Are there reasons a jet injector might be medically preferred over a hypodermic needle (or vice versa)? -Grammaticus Repairo (talk) 15:33, 10 June 2008 (UTC)

I've used it (once) and it was completely painless, and only produced a small wheel reaction. —Preceding unsigned comment added by Fuzbaby (talk • contribs) 13:36, 27 May 2009 (UTC)

The scar produced by the jet injection devices is pretty unique and long-lasting from a visual standpoint, it might be worth adding both a textual description and picture into the Health/Physiological Impact section(s). Virtualjmills (talk) 02:57, 27 September 2010 (UTC)

Can you provide a link or reference for this scar? Any possibility that it arose from a smallpox injection? The smallpox vaccination process produces a scar no matter how it's administered. Pyrilium (talk) 17:00, 7 January 2011 (UTC)

Star Trek 1966

I don't believe the term "hypospray" was used until either 1987 (Star Trek: The Next Generation) or, at the earliest, the movies that started in 1979. In the old series, I think the word "hypo" was used. In "The Return of the Archons", Kirk tells Reger that McCoy will give Reger's daughter "a shot". The term "hypo" is particularly prominent in the first few minutes of "City on the Edge of Forever".

While the term "hypospray" might have occurred in the movies, I can most clearly recall Gates McFadden first uttering the word as Dr. Crusher in the episode "The Naked Now", trying to combat the disease of that episode. GBC (talk) 03:38, 2 May 2009 (UTC)

Biomatter contamination

This article is avoiding the most important point: IS THERE, or is there not a jet injector that is reusable on different patients without sterilization or part replacement, yet WITHOUT RISK OF DISEASE TRANSMISSION?! Aadieu (talk) 03:28, 5 October 2009 (UTC)

Not really, no. The classic nozzle-style jet injectors all seem to suffer from blowback of some form or another.

The closest you can get would be a magazine-style disposable-needle jet injector of which there seems to be exactly one which fits the mass-vaccination model for human patients at this time (LectraJet® HS) -- http://www.dantonioconsultants.com/prod_ji_human.htm -- It looks like the parent device has US FDA 510(k) clearance as of December 2009, but the only study listed -- http://clinicaltrials.gov/ct2/show/NCT00987350 -- doesn't mention which sub-type of the LectraJet design is being used.

The W.H.O. page discussing the need for such a system appears to have been authored somewhere around 1998 -- https://apps.who.int/vaccines-access/injection/injection_safety/safe_injections_choosing_technologies.htm Virtualjmills (talk) 03:28, 27 September 2010 (UTC)

Strange unit

Is it just me, or does the whole section "Types of jet injector" read more like an advertisement for a particular company's products rather then a neutral explanation of what types there really are? Should this maybe be reviewed or vetted or something? 184.65.105.23 (talk) 02:31, 26 February 2013 (UTC)

Under the section labelled "Concerns", there is the strange unit "one millionth of a millilitre". That is equal to one nanolitre, of course, and I think this latter unit should be used instead, to stick with the SI rules. If there is a concern that the reader may not have a clear idea of how much volume one nanolitre is, then the equivalence could be given in parentheses or a link created to the article "nanolitre". — Preceding unsigned comment added by 93.146.163.99 (talk) 15:55, 18 July 2012 (UTC)
