Healthcare providers (doctors, nurses, and anyone providing injections) should never reuse a needle or syringe either from one patient to another or to withdraw medicine from a vial. Both needle and syringe must be discarded once they have been used.
Overview. Some people with diabetes use their insulin syringes and lancets more than once to save money. But makers of syringes and lancets do not recommend using them more than once. Talk with your doctor before reusing these items.
Sterility and your safety. Pen and insulin syringe needles are designed for single use, and should only be used once—they are no longer sterile after use.
If you have to share, thoroughly clean your needles and works with bleach and water after each use and before reusing. If you are at risk because you are injecting drugs now or have injected in the past, get tested for HIV and hepatitis.
Needles intended for medical use should be used only one time, and not reused. If you must reuse a needle, sterilization can be tried at home, but will never provide a complete, 100 percent guarantee. New needles come packed in sterilized packaging.
People who inject drugs can get Hepatitis C from: Needles & Syringes. Sharing or reusing needles and syringes increases the chance of spreading the Hepatitis C virus. Syringes with detachable needles increase this risk even more because they can retain more blood after they are used than syringes with fixed-needles.
Bacteria found on the needles was mainly bacteria found naturally on skin (staphylococcus epidermidis). Whilst this form of bacteria is usually harmless, re-use of needles could increase the risk of contamination of more harmful bacteria.
The safest practice is for a syringe and needle to be used only once to administer a medication to a single patient, after which the syringe and needle should be discarded. This practice prevents inadvertent reuse of the syringe and protects healthcare personnel from harms such as needlestick injuries.
Recapping needles is extremely dangerous because it can result in accidental punctures of the fingers or hand, which can lead to potential exposure to hazardous chemicals, drugs, or infectious biological agents.
Sterility. Once a standard syringe is filled with a medication, it will remain optimally effective, or sterile, for approximately 12 hours.
Injecting a small air bubble into the skin or a muscle is usually harmless. But it might mean you aren't getting the full dose of medicine, because the air takes up space in the syringe.
Both needle and syringe must be discarded once they have been used. It is not safe to change the needle and reuse the syringe – this practice can transmit disease. Reusing a needle or syringe can put patients in danger of getting hepatitis C virus (HCV), hepatitis B virus (HBV), and HIV.
American researchers found that under the right circumstances, HCV remained viable in a syringe for up to 63 days. Circumstances that increased HCV infectivity include syringes with detachable needles, lower temperature and larger volume syringes.
HBV can survive for up to one week under optimal conditions, and has been detected in discarded needles (6,18). A case of HBV acquired from a discarded needle used by a known HBV carrier has been reported (4).
A recent analysis of several studies revealed an overall 0.2% risk for infection among those exposed to HCV-antibody-positive blood through needlestick or sharps injuries (35).
Blood and body fluids, such as saliva, semen and vaginal fluid, can contain viruses that can be passed on to other people. If you have contact with a person's blood or body fluids you could be at risk of HIV, hepatitis B or hepatitis C, or other blood borne illnesses.
Hepatitis C is spread by direct contact with hepatitis C-infected blood. For example, if infected blood came into contact with an open sore or a cut in your hands, you may become infected.
Needle-stick injuries
Once someone has used a needle, viruses in their blood, such as hepatitis B, hepatitis C or HIV, may contaminate it. This includes needles used to inject illegal drugs. Blood can also contaminate sharps.
Healthcare providers (doctors, nurses, and anyone providing injections) should never reuse a needle or syringe either from one patient to another or to withdraw medicine from a vial. Both needle and syringe must be discarded once they have been used.
If you see blood in the syringe, you have hit a blood vessel. If you hit a vessel, pull the needle out of the skin. Get rid of the needle and syringe, and prepare a new syringe with medicine.
Answer 1: It is all about pressure. When you plug upon the nozzle, there is no way for the pressure of the fluid to rise above a certain value, so pushing in is opposed by the fluid pushing back on your finger, it gets hard!
Blood should be tested very soon after it's drawn, usually within about four hours. Serum samples should be separated from whole blood within two hours of the blood draw.
To sterilize using the boiling method:
Bring the water to a boil. Place the needles and syringes in the pot. Let boil for twenty minutes.
Supplies wrapped in double-thickness muslin comprising four layers, or equivalent, remain sterile for at least 30 days. Any item that has been sterilized should not be used after the expiration date has been exceeded or if the sterilized package is wet, torn, or punctured.
