The present invention relates to a blood vessel sensing apparatus and method for a syringe.
In general, vascular injection is a method of injecting a drug directly into a blood vessel by inserting an injection needle into a blood vessel for drug treatment. Vascular injections are widely used when injecting drugs such as electrolytic dissemination, blood supply, and antidote into the blood or expecting quick drug efficacy because the drug has a merit that the drug reaches the necessary tissues of the body through the heart within a few minutes, have.
The insertion of an injection needle for an injection of a blood vessel by the practitioner can be performed without difficulty if the blood vessel of the patient is intuitively seen, but otherwise the pain is caused to both the patient and the patient.
In other words, even for a skilled practitioner, patients suffering frequent blood sampling or injection of blood vessels will not be able to see the blood vessels due to stress, and the elderly or women will have difficulty in recognizing blood vessels due to thick skin layers. In the case where the patient's blood vessel is not intuitively visible, since the injection needle is inserted through several failures, there is a problem that the operator or the patient receiving the insertion suffers a lot of pain.
