Medical Needles: How Small Is Small Enough?

People rarely look forward to getting a needle. They worry about it hurting. They wonder whether they will bleed or get a bruise. This is true for giving blood at a clinic or getting a vaccine. To reduce the pain, some researchers have looked at size. They believe using smaller medical needles in procedures will reduce the anxiety and actual pain.
Micro Fine Needles
A fine needle is currently being manufactured that is actually smaller than the tiny 30-gauge. The 30-gauge medical needles are commonly employed to deliver insulin. Several companies have adapted their current manufacturing procedure to create these micro fine needles. Gauges for them currently range from 31 to 33. Currently popular is a pen needle with a gauge of 31.
Research on these newer needles indicates a demonstrable reduction for both pain and bleeding. Yet, recorded patient satisfaction only occurred after the use of a lubricant. Once the 33-gauge needles were lubricated, it appeared to reduce the perceived pain by the patient. This may be the result of a reduction in the friction between the needle and the entry point on the skin. This would decrease the amount of force required for the needle entry.
Micro needles
Another way of reducing the pain and potential bleeding of medical needles is to make them between 1–3 mm in length. These needles are short and, pun intended, to the point. They are best suited for delivering vaccines into the skin – particularly the top layers. Research into the use of these medical needles for vaccines for certain animals and humans seems to indicate promise for the application to other drug usage.
Research also indicates that even smaller needles – those that are measured in sub millimeters, can be very effective at reducing pain. This is applicable as long as the needles only have to deal with the top most layer of the skin. They are able to penetrate this successfully but are not suitable for intramuscular procedures. Micro needles, therefore, are best suited for vaccines and insulin shots.
Limitations
Manufacturing of smaller medical needles is occurring. It is not, however, without its issues. Limiting progress are three factors:

* The needles must be small

* They must also have mechanical strength

* The manufacturer needs to produce them in a cost effective manner

Medical needles come in all sizes. The current aim to reduce pain and increase patient acceptance has resulted in the fabrication of smaller needles. Yet, manufacturing issues can and do effect production. Moreover, such smaller needles are not capable of application for all procedures. They cannot handle practices involving deep, injections, rapid delivery of large volumes or large particulate material. When it comes to finding the right type of Medical Needles consider what we have at Bulk Syringes. We can provide any type and amount at reasonable prices.
