Needle achieving rapid diffusion

Abstract

The invention discloses a rapid dispersion needle, which comprises a needle body, one end of the needle body is provided with a needle cap, and the needle body and the needle cap are fixedly connected, wherein, the other end of the needle body is provided with a V-shaped sharp end. There are a number of needle outlet holes on both sides of the tip, and the opening direction of the needle outlet holes is parallel to the needle body. There are a number of front end liquid outlet holes and a number of middle end liquid outlet holes on the needle body. The front end liquid outlet holes are located behind the sharp end. , the opening direction of the liquid outlet hole at the front end is perpendicular to the needle body, the liquid outlet hole at the middle end is located in the middle of the needle body, the opening direction of the liquid outlet hole at the middle end faces the needle cap, and the angle between the liquid outlet hole at the middle end and the needle body is 12-18 degrees, a scale line is set on a section of the needle body between the liquid outlet hole at the middle end and the needle cap, and the distance from the sharp end to the liquid outlet hole at the middle end is 1.2-1.8cm. The invention is simple in structure and easy to use. In one puncture operation, the anesthetic drug can be scattered at multiple points through the anesthetic needle, the area contacting the anesthetic drug can be enlarged as far as possible, and the time required for anesthesia can be shortened.

Description

Technical field: [0001] The present invention relates to medical instruments, in particular to a rapidly dispersing needle. Background technique: [0002] During the operation of the operation, the anesthesiologist needs to control the depth of anesthesia for the patient, so that the patient is in a painless state, so as to ensure the smooth operation of the operation and the safety of anesthesia. As an anesthesiologist, we need to relieve the pain of the patient and manage the vital signs of the patient, including breathing, heart rate, blood pressure, heart, nervous system, liver and kidney function, etc. In general surgery, clinical anesthesia often needs to register anesthetic drugs at the site to be operated, and use a syringe to perform subcutaneous puncture registration to this area to cause regional anesthesia. For example, if a larger wound is sutured, anesthesia around the wound is required. An ordinary syringe is usually used to inject drugs during anesthesia....

AI Technical Summary

Problems solved by technology

Ordinary syringes are usually used to inject drugs during anesthesia. However, for open wounds, a subcutaneous puncture point injects anesthesia drugs, which takes a long time for anesthesia. In order to perform operations faster and treat patients, it is necessary to be able to Therefore, the needle on the traditional syringe faces one direction and sprays anesthesia at one point, which is often difficult to meet this requirement, resulting in multi-point puncture for anesthesia
