Method Of Making Syringes Blunt-tipped Needle
Dr.c | Updated: Sep 28, 2017

The syringe barrel can be made of plastic or it can be made of all-glass Blunt-tipped Needle and usually has a scale indication on the volume of the liquid in the Blunt-tipped Needle. Blunt-tipped Needle can be sterilized by autoclave, but because the plastic Blunt-tipped Needle is less expensive to handle, the modern medical Blunt-tipped Needle is mostly made of plastic, which further reduces blood transmission The risk of the disease.
Infusion bag permeability tester test principle: the use of the principle of pressure method design, the pre-processed samples placed in the upper and lower test chamber between the two sides of the sample to form a constant pressure, the gas in the pressure difference Under the action, by the high pressure chamber through the membrane to the low pressure chamber penetration, monitoring the pressure of the low pressure chamber can be calculated to measure the blocking parameters of the test sample.
When the mandrel is pulled out, the liquid or gas is sucked from the tip of the barrel, and the liquid or gas is extruded when the mandrel is pushed in. The process of extracting or injecting gas or liquid with Blunt-tipped Needle and Blunt-tipped Needle is called injection.
With the development of medical technology, all-glass Blunt-tipped Needle also came into being, this Blunt-tipped Needle without needles, but with a high-speed high-pressure injector drugs through the skin into the body. This way can drastically reduce the number of doctors and nurses using the needle when Blunt-tipped Needle is accidentally tied to their own accident. Blunt-tipped Needle, or Blunt-tipped Needle, can be used to inject insulin, both of which have the advantages of simple operation, accurate measurement, needle tip and so on, to facilitate the independent operation of diabetic patients and reduce the pain of patients sense. It was also argued that surgeons in Iraq and Egypt had developed a similar Blunt-tipped Needle for the removal of cataracts in the eyes of patients with a hollow glass tube in the 9th century AD, which was still used at least in 1230 , In the 20th century this method has been improved.
Whether it is a special Blunt-tipped Needle or insulin pen needle, are disposable supplies, which means that after the injection should be replaced needle. Repeated use of the needle will make the needle blunt, increase the pain, and may even cause skin infections.
 People in childhood if the first contact with the injection, will be the tip of the needle into the flesh when the pain to cry, so they are the most unpopular "welcome" modern medical tools. However, if there is no full glass Blunt-tipped Needle, there will be no intravenous infusion, many people will be killed. Do not underestimate this little Blunt-tipped Needle, in fact it also has a long history.
Blunt-tipped Needle consists of a syringe with a small hole at the front and a matching piston stem. Blunt-tipped Needle is used to inject small amounts of liquid into areas that are not accessible to other methods or from those places. When the mandrel is pulled out, the liquid or gas is sucked from the tip of the barrel, and the liquid or gas is extruded when the mandrel is pushed in. The process of extracting or injecting gas or liquid with Blunt-tipped Needle and needles is called injection.
As early as Blunt-tipped Needle was invented, there was already a doctor's treatment of infusion, but because of the use of natural tools, so that the patient had an infection. It is generally believed that the origin of Blunt-tipped Needle for medical use was Scottish doctor Alexander Wood and Charles Prampez of France, who worked together in 1853 to achieve this process. Alexander uses this new tool to subcutaneously inject morphine into the patient to treat sleep disorders. Unfortunately, however, Alexander's wife died because of herself injecting morphine overdose. Then, Alexander has improved the Blunt-tipped Needle: the needle with the scale, the needle is more fine. This series of improvements also attracted the attention of many doctors, and Blunt-tipped Needle has been widely used.
It was also argued that surgeons in Iraq and Egypt had developed a similar Blunt-tipped Needle for the removal of cataracts in the eyes of patients with a hollow glass tube in the 9th century AD, which was still used at least in 1230 , In the 20th century this method has been improved.
