What is the difference between an indwelling needle and a regular needle?

Everyone must be familiar with indwelling needles. Indwelling needles have very obvious advantages, such as being able to effectively protect the patient's blood vessels and minimize the patient's pain. Especially for those patients who need multiple infusions a day, it is best to choose indwelling needles. This can avoid multiple injections and even reduce costs. The following is a detailed introduction to the many differences between indwelling needles and ordinary needles.

The difference between an indwelling needle and a regular needle:

There is nothing mysterious about indwelling needles. Have you seen intravenous infusion? It's the same as that one, except that normal infusions use needles, while indwelling needles use very thin plastic tubes. The center of the puncture needle is a steel needle, with a thin plastic tube on the outside. After the puncture and bleeding, the central steel needle is pulled out and the plastic tube remains in the blood vessel. Just connect the infusion line and you can start the infusion. After the infusion, you can cover it with the heparin cap and then you can move normally. You don't need to get a needle inserted during the next infusion, just insert the needle into the small leather stopper. The advantage is that it can avoid repeated puncture pain. For example, if a person needs to receive antibiotics three times a day, without using an intravenous needle, he or she will either have to hang the drip and waste time, or get injected three times a day.

It would be great if I had an indwelling needle. I only need to go to the hospital for infusion, and I can go home after taking the medicine and go back when the time comes. It is very convenient. There is a heparin cap on the indwelling needle, so it doesn't matter if a little blood returns, it won't cause blockage. You will see blood in the plastic tube, and it will be returned during the next infusion. An indwelling needle can be used for at least 3 days at a time, and occasionally for up to a week. At the end of the use, the blood vessels will be irritated, which will make the infusion difficult, and it is time to replace the indwelling needle. Since the indwelling needle is a very thin plastic tube left in the blood vessel, without the steel needle, the hand's movement is not restricted and the blood vessel will not be punctured, so it is very safe. Do you understand?

If long-term infusion is required, it is recommended to use an intravenous catheter for infusion, because using an intravenous catheter has several advantages: it can be left in place for 3-5 days, reducing the number of punctures, protecting the patient's blood vessels, and reducing the patient's pain. Indwelling needles have been used in the country for more than ten years, so please feel free to use them.
