Skin test needle and application thereof

Abstract

The invention belongs to a medical instrument, in particular to a skin test needle, including a needle tube and a needle, and a bracket placed on the epidermis of the patient's forearm. The needle tube or needle is placed obliquely on the bracket such that a needle insertion angle is 12 to 14 DEG, and the needle entry angle is an included angle between the axis of the needle tube and the skin surface of the patient's forearm. The application changes the traditional 5 DEG needle insertion into 13 DEG included-angle needle insertion and reduces a length of the needle tube to ensure that the injection is performed to an accurate position to complete a qualified skin test, which is easy for the doctor to operate, easy to get started, greatly reduces the pain of the patient, and significantly improves the success rate of the skin test of a child patient.

Description

technical field [0001] The invention belongs to medical tools, in particular to a skin test needle and a using method thereof. Background technique [0002] Clinically, a skin test needle is used to inject the test solution into the lower part of the patient's forearm to form a skin mound to determine whether the patient is allergic to the drug. The current skin test needle generally uses a 1ml syringe with a length of about 127mm, wherein the needle length is 16mm, and the bevel of the needle tip is 1.5mm. Clinical norms and professional textbooks require injections to be made at an angle of 5° between the needle and the epidermis. In actual practice, patients will experience pain when receiving skin test injections, especially children with low endurance, and will move around when they feel pain. It is easy for the needle to slip and bend, leading to the failure of the skin test injection, and having to inject again. The comfort of the patient is poor, and it is also very...

Problems solved by technology

Clinical norms and professional textbooks require injections to be made at an angle of 5° between the needle and the epidermis. In actual practice, patients will experience pain when receiving skin test injections, especially children with low endurance, and will move around when they feel pain. It is easy for the needle to slip and bend, leading to the failure of the skin test injection and having to inject again. The patient's comfort is poor, and it is also very time-consuming and labor-intensive for the doctor.
