These are mainly useful in cases where one needs to rapidly inject the same substance into multiple patients (say, a company of soldiers getting inoculated - no need to change needles, or redraw substance into a small syringe each time, when you can just sort of pressure-hose it into the patients). Another condition usually is that the substance must be allowed to go into muscle tissue, not directly into blood circulation. <br /><br />There are a couple of hurdles before we can have Trek-style hyposprays. A jet that would be localized enough to hit blood vessels and not the surrounding tissue is a difficult goal - you can use a sharp jet on a vein close to skin, but it's likely to leave a nasty hole. Also, you cannot adjust the depth of injection very easily. And you cannot draw blood.<br /><br />Trek hyposprays could solve many of the problems by using "virtual needles" - hollow tubes made out of forcefields. Today's or tomorrow's tech could do the same with needles made out of an inert annular jet of saline solution, within which the substance will flow (either in or out). Both alternatives will still leave holes, but at least they will be more sterile than needles.<br /><br />Timo Saloniemi <br /> </font> </td></tr> <tr bgcolor="#A3B9CC"> <td valign="top" width="18%"> <font size="3" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> <b>Woodside Kid</b> <br /><small>Member # 699</small> </font></td> <td width="82%"> <font size="2" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> <img src="https://flare.solareclipse.net/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.write(timestamp(new Date(2003,5,11,7,48,0), dfrm, tfrm, 0, 0, 0, 0)); </script><noscript><span class="dateformat-0">June 11, 2003</span> <span class="timeformat-0">07:48 AM</span></noscript><hr /> </font> <font size="3" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> I received a good amount of my shots that way in AF basic training back in '83. One drawback that a number of my fellow airmen discovered is that you had to keep your arm still during the injection. If you flinched and moved, the high pressure liquid gave you a nice little cut on your arm. I don't know if they've changed the process since then, but Timo is right; it did make the procedure a good deal faster. <br /> </font> </td></tr> <tr bgcolor="#E5EAEF"> <td valign="top" width="18%"> <font size="3" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> <b>Proteus</b> <br /><small>Member # 212</small> </font></td> <td width="82%"> <font size="2" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> <img src="https://flare.solareclipse.net/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.write(timestamp(new Date(2003,5,11,13,34,0), dfrm, tfrm, 0, 0, 0, 0)); </script><noscript><span class="dateformat-0">June 11, 2003</span> <span class="timeformat-0">01:34 PM</span></noscript><hr /> </font> <font size="3" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> I thought hyposprays used micro-transport technology to simply deliver the medicine into the vien without actual penitration. <br /> </font> </td></tr> <tr bgcolor="#A3B9CC"> <td valign="top" width="18%"> <font size="3" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> <b>The Mighty Monkey of Mim</b> <br /><small>Member # 646</small> </font></td> <td width="82%"> <font size="2" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> <img src="https://flare.solareclipse.net/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.write(timestamp(new Date(2003,5,11,15,20,0), dfrm, tfrm, 0, 0, 0, 0)); </script><noscript><span class="dateformat-0">June 11, 2003</span> <span class="timeformat-0">03:20 PM</span></noscript><hr /> </font> <font size="3" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> </font><blockquote><font size="1" face="Trebuchet MS, Verdana, Helvetica, sans-serif">quote:</font><hr /><font size="2" face="Trebuchet MS, Verdana, Helvetica, sans-serif">Originally posted by Proteus:<br /><strong> I thought hyposprays used micro-transport technology to simply deliver the medicine into the vien without actual penitration. </strong></font><hr /></blockquote><font size="2" face="Trebuchet MS, Verdana, Helvetica, sans-serif">Uhh...no. <br /> </font> </td></tr> <tr bgcolor="#E5EAEF"> <td valign="top" width="18%"> <font size="3" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> <b>Saltah'na</b> <br /><small>Member # 33</small> </font></td> <td width="82%"> <font size="2" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> <img src="https://flare.solareclipse.net/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.write(timestamp(new Date(2003,5,18,11,6,0), dfrm, tfrm, 0, 0, 0, 0)); </script><noscript><span class="dateformat-0">June 18, 2003</span> <span class="timeformat-0">11:06 AM</span></noscript><hr /> </font> <font size="3" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> Technology it goes. <br /> </font> </td></tr> <tr bgcolor="#A3B9CC"> <td valign="top" width="18%"> <font size="3" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> <b>Toadkiller</b> <br /><small>Member # 425</small> </font></td> <td width="82%"> <font size="2" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> <img src="https://flare.solareclipse.net/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.write(timestamp(new Date(2003,5,20,6,20,0), dfrm, tfrm, 0, 0, 0, 0)); </script><noscript><span class="dateformat-0">June 20, 2003</span> <span class="timeformat-0">06:20 AM</span></noscript><hr /> </font> <font size="3" face="Trebuchet MS, Verdana, Helvetica, sans-serif"> Actually it has progressed somewhat from what some may recall from "boot camp days". <br /><br />The hospital I work at recently bought a "Bioject" brand product that looks somewhat like Bones' hypospray. Basically flashlight sized it has a CO2 cartridge (like from a pellet gun) that drives a plunger which forces the liquid you're using (vaccine, whatever) out of the special syringe fast enought that the fluid itself acts like a very fine needle. Doesn't leave much of a hole at all and feels like someone flicking you with their finger.<br /><br />We wanted it because with no needle there is no chance that the health care worker can stick themselves after giving the shot - it isn't primarily a patient centered thing, though many perfer it to needles as it doesn't seem as scary I guess. <br /><br />The syringe is disposable so no part of the device touches two patients, and it is so quick that you avoid the movement issues....<br /><br />I don't own stock in the thing or anything, but it is neat and I'm nerd enough to be thrilled to have a "hypospray".... <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
