Abstract
The utility model belongs to the technical field of medical deivice, relating to an epidural piercing manograph, comprising a piezometer tube. The piezometer tube is arranged in a transparent holding handle. One end of the piezometer tube is provided with an injecting mouth, and the other end is connected with the end of a piercing needle. Colored liquid is provided in the piezometer tube, when the piercing needle enters an epidural cavity, the negative pressure of the epidural cavity makes the quantity of liquid in the piezometer tube vary, and the success that the piercing needle enters the epidural cavity is confirmed. The utility model can accurately measure whether the piercing needle arrive ar the epidural cavity or not, simultaneously, the operation is convenient, and the piercing success rate is increased.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of epidural puncture manograph.
Background technology
Epidural puncture is the operation of often using in the operation, during puncture generally is to judge the position that syringe needle reached by doctor's estimation and feel the easy like this error that occurs, thereby the carrying out of influence operation.
Technology contents
The purpose of this utility model provides a kind of puncture needle that can clearly illustrate and whether enters the epidural puncture manograph of epidural space, to overcome the deficiencies in the prior art.This utility model has a pressure-measuring pipe, pressure-measuring pipe is installed in the transparent grab handle, pressure-measuring pipe one end has liquid injection port, the other end is and the puncture needle link that when carrying out epidural puncture, the link that puncture needle is installed in pressure-measuring pipe punctures, the colored liquid of packing in the pressure-measuring pipe, after puncture needle entered epidural space, its negative pressure that has changed the amount of fluid in the pressure-measuring pipe, thereby confirmed that puncture needle enters the epidural space success.This utility model can be measured piercing needle exactly and whether arrive epidural space, is convenient to operation simultaneously, improves puncture success rate.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
Specific embodiment
1 is grab handle of the present utility model among the figure, and pressure-measuring pipe 2 is equipped with in the holder, and an end has liquid injection port, the other end is the link that is connected with puncture needle, have scale on the pressure measurement tube wall, can clearly illustrate the variation of liquid in pipe, holder and pressure-measuring pipe are transparent.
