Use of Disposable Needles

Use of Disposable Needles

Can medical needles be reused? Most people answer this question firmly of course not, but there are always a small number of people who are lucky, or are skeptical that medical institutions are using all unused single-use needles for patients. Let’s take a look at this problem today.

First of all, we must be clear that medical needles cannot be reused. This is absolutely prohibited. The needles used for the second time are likely to cause biological pollution or the spread of infectious diseases. For example, part of the spread of AIDS is through The needle used for the second time is extremely irresponsible to the patient and can be regarded as a serious medical malpractice. Therefore, the secondary use of needles is absolutely prohibited in regular medical institutions, and this situation basically does not occur, because:

1. All needles are individually sealed and packaged for one-time use. This ensures that the packaging bag needs to be torn open for each needle before use, and the torn needles in the packaging bag are easily contaminated by the outside even if they are only placed on the tray for a period of time. If you see a fully packaged needle, don’t worry, it’s completely safe.

2. There is a needle cap on each lancet. If it is to be reused, the needle cap must be put back on the needle, which itself is a process that can easily cause injury.

3. If it is a blood collection needle that has been used, there will be obvious blood stains behind the needle, which can be clearly seen by the naked eye, and medical staff can usually find it at the first time.

4. After each lancet is used once, the negative pressure inside will be destroyed, and the used lancet will lose its value for secondary use.

5. The most important thing is that every medical staff will receive extremely strict training before going to work. Throwing the needle back into the sharps box after use has become their instinctive muscle memory.

These factors work together to ensure that every patient uses clean and safe needles, preventing the spread of infectious diseases between patients. Therefore, to treat diseases, we have to go to formal medical institutions. Informal medical institutions still have the risk of secondary use of medical devices. In addition, some individuals often use needles for the second time because of their lack of hygiene awareness. For example, some diabetic patients often make such mistakes when injecting insulin into themselves.

According to the ninth edition of the Global Diabetes Map released by the International Diabetes Organization in 2019, the number of diabetic patients in the world has reached 463 million. Due to the long treatment cycle of diabetes, many patients will repeatedly apply needles. Although this needle has always been used by one person, this There is still a high security risk.

First, reused needles have an increased risk of breakage. Under the observation of the microscope, even if the needle was injected once, the silicon layer had obvious changes, and the needle was slightly hairy. After repeated use, the toughness and strength of the needle were greatly reduced, and the needle tip appeared burrs, bends and barbs. , causing bleeding at the injection site, abrasions, and increased pain. In order to reduce the pain during injection, the needles on the market are very thin at present. The thinner the needle, the easier it is to break. The broken needle cannot be seen by the naked eye because of its small size, and cannot be pulled out with bare hands. Poor vision and sensory sluggishness are simply not detectable. Such a tiny foreign body is easy to swim in the body, and once it “runs” to important parts, such as large blood vessels, the consequences will be disastrous.

Second, reuse of needles is likely to cause injection site infections. Reusable needles are repeatedly exposed to the air for a long time, and it is inevitable for microorganisms to “visit”. In this way, bacteria on the air and needle tips enter human tissues repeatedly with the needles, increasing the risk of local infection and contaminating the medicinal solution. The efficacy of the medicinal solution.

Also, reusing needles can cause needle blockages. Insulin injection itself is not “pure water”, but a drug “suspension”. There is a certain amount of drug residue in the used needle. Repeated use, the residue in the needle will condense into insulin crystals, which can easily cause needle blockage. affect the next injection. A considerable number of diabetic patients are elderly, with poor eyesight, unable to see whether the liquid medicine is really discharged and injected, and the “empty” injection caused by the blocked needle cannot be detected.

Finally, repeated use of needles may affect insulin concentration and injected dose. This is because the repeated use of needles can easily lead to the leakage of insulin in the needles, which reduces the drug concentration and greatly affects the therapeutic effect of glucose control.

In general, disposable needles must be used, whether for the prevention of infection or for better treatment effect and treatment safety. Needles are sharp objects, which are easy to cause injury, and can cause biological contamination if discarded at will. Therefore, they should be thrown into the sharps box of professional medical containers immediately after use. If you need a professional and reliable sharps box, please log in to BOYUE
