Lumbar spinal needle special for newborns

Abstract

The invention belongs to the field of auxiliary medical instruments, and particularly relates to a lumbar spinal needle special for newborns. The lumbar spinal needle comprises a lumbar spinal needlebody and a fixed cap, wherein a through hole is formed in the bottom of the fixed cap; the lumbar spinal needle body penetrates through the through hole and is movably connected with the inner wall ofthe through hole; a micro air pump is arranged on the outer wall of the fixed cap; the micro air pump is communicated with the inside of the fixed cap. According to the lumbar spinal needle special for the newborns, the micro air pump is used for keeping air pressure inside the fixed cap, so that the lumbar spinal needle is sucked at a puncture part of a patient to keep the puncture needle stay at a position fixed relative to the patient, to prevent needle running; an air pressure sensor monitors the air pressure inside the fixed cap in real time; a micro controller can guarantee dynamic balance of the inside air pressure; the flexible holding assembly and the lumbar spinal needle body can be removed without obstructing the view; by threaded connection with the rotating lumbar spinal needle body and cooperation with scale lines, a puncture depth can be guaranteed, and convenience and reliability are achieved; a fixed waistband and fixed shoulder straps cooperate to assist in localization, so as to further prevent the lumbar spinal needle body from moving during activity of the patient.

Problems solved by technology

[0003] During the use of lumbar puncture needles, there are many problems. First, the puncture site needs to be sterilized before puncture, which is very troublesome and requires another decontamination device. In addition, the current lumbar puncture needles are simple in structure and have no scales. As for the indicator mechanism, there is only one needle handle in the holding part. Since newborns are generally more active, it is easy to cause the needle body to shake during puncture, and it is difficult to control the puncture depth. Therefore, the doctor's puncture level is required to be high. The handle of the lumbar puncture needle is fixedly connected with the lumbar puncture needle, which may block the line of sight when puncturing and taking fluid, causing inconvenience to medical staff
