Visible scale puncture needle for pediatric anesthesia and use method

Abstract

The invention discloses a visual scale puncture needle for pediatric anesthesia and a use method, and relates to the technical field of medical instruments. The visual scale puncture needle comprises a needle head, a needle core and a needle head shield, wherein scales are arranged on the peripheral side surface of the needle head; the scales are positioned on the rear half section of the needle head and are gradually increased from the needle tip to the needle tail; needle head grooves for placing needle heads are formed in the needle head shield along the axial direction; the needle head shieldcomprises a first shield and a second shield, the rear end of the first shield is rotationally connected with the front end of the second shield, and an auxiliary positioning device is fixedly connected to one surface of the needle head shield. According to the invention, the scales are arranged on the peripheral side face of the needle head, and the scale lines are arranged on the rear half section of the needle head, so that shielding interference is avoided when the scales are read in the puncture process; the needle head shield can be folded to assist the needle head in puncturing, an auxiliary positioning device of the needle head is arranged on the needle head shield, and the auxiliary positioning device is used in cooperation with scales on the needle head, so that the purpose of accurately recognizing the puncturing depth is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a puncture needle with visible scale for pediatric anesthesia and a method for using the needle with visible scale for anesthesia in children. Background technique [0002] Lumbar puncture is one of the commonly used clinical diagnosis and treatment techniques. It is often used to monitor the properties of cerebrospinal fluid, measure intracranial pressure, understand whether the subarachnoid space is blocked, and replace cerebrospinal fluid. At present, lumbar puncture needles No. 7 and No. 9 are commonly used for lumbar puncture in children. Due to the long needle body, heavy needle tail, and poor cooperation in children, it is often difficult to fix, and the puncture is displaced, resulting in puncture failure. Case. In addition, children's subcutaneous tissue is thin, ligaments and dura mater are also thin, resulting in no obvious feeling of falling during the punctu...

AI Technical Summary

Problems solved by technology

The needle shield can be folded to assist needle puncture, and an auxiliary positioning device for the needle is set on the needle shield. The auxiliary positioning device is used in conjunction with the scale on the needle, which solves the problem that the existing puncture depth is difficult to grasp

Another object of the present invention is to provide a method for using a puncture needle with a visual scale for pediatric anesthesia. By folding the needle shield into a tool for assisting needle puncture, the positioning accuracy of the puncture point is improved, and at the same time, the needle is kept at an angle perpendicular to the skin. Puncture into the body of the child, solving the problem of unstable needle during puncture and increasing the risk of surgery
