Tenko Medical hypodermic needles
There are three main types of medical needles that can be used for injections, samples and sutures.
There are two main injection routes: hypodermic and intravenous.
- Hypodermic needles: allow the administration of a drug in injectable form into the patient’s subcutaneous cellular tissue. This type of injection can be performed in hospitals, clinics, care centers or even at home. The needles are used with a prepared syringe. There are special devices, called injection pens, that allow you to easily and accurately adjust the dose injected. In this case the medication comes in the form of pre-filled cartridges, which prevents having to take the dose from a bottle. The needle must be replaced after each use. This type of needle is commonly used for insulin injections or certain anticoagulants.
- Intravenous injection needles : allow the administration of a liquid, often a drug solution, directly into a vein. A tourniquet is placed ten centimetres above the injection site. Intravenous injections allow for a faster therapeutic effect than hypodermic injections. They also avoid the risk of reactions with subcutaneous or muscle tissue (which can cause pain, edema or even necrosis in extreme cases).
These needles are used for two main types of sampling:

- Blood samples: in the case of blood samples by venipuncture or arterial puncture, the use of a tourniquet may be necessary to make the vein protrude. Some blood sample or infusion needles are equipped with a premounted adapter to connect to a sample body.
- Biopsies: most biopsy needles are extremely thin and strong, as in the case of a lumbar puncture needle for example. For this procedure, the needle penetrates deep into an intervertebral space in the lumbar spine and punctures the dura mater, the rigid fibrous membrane that protects the spinal cord. A sample of cerebrospinal fluid is taken to detect the presence of certain diseases, such as bacterial meningitis. This is performed under local anesthesia.
Surgical suture needles: allow, as their name indicates, the suture of different types of tissue by means of a suture that may or may not be absorbable.
