Description

A kind of novel thoracentesis needle
Affiliated technical field
This utility model relates to a kind of novel thoracentesis needle that is fit to extract clinically hydrothorax, pneumatosis or intracavitary administration, belongs to technical field of medical instruments.
Background technology
Thoracentesis needle great majority commonly used clinically at present are the metal puncture pin, make things convenient for drawing liquid, bleed or intracavitary administration through its tail end connection rubber tube or other flexible pipes.The operator is earlier with syringe infiltration anesthesia patient site of puncture skin and the subcutaneous tissue of drawing local anaesthetics during thoracentesis, after the anesthesia just with thoracentesis needle along anesthesia direction secondary puncture drawing liquid, bleed or intracavitary administration.The operator anaesthetizes the back secondary puncture not only increases the injury of patient's body, and maybe because of puncture deeply, needle point is sharp keen causes lung tissue to be damaged and can not keep somewhere puncture needle for a long time because of poor plasticity.When the patient needed the repeated multiple times thoracentesis, operator's frequent puncture not only obviously increased the injury of patient's body and mind, wastes medical manpower and materials, increases patient's medical burden, also possibly cause the generation of malpraxis even malpractice.
Summary of the invention
In order to overcome the deficiency of conventional thoracentesis needle secondary puncture, repeated localised puncture and difficult long-time indwelling etc., this utility model provides a kind of novel thoracentesis needle.This thoracentesis needle is simple in structure, not only almost can be while anaesthetizing thoracentesis, can alleviate the patient suffering and avoid the lung tissue damage; Can also keep somewhere for a long time in the thoracic cavity and avoid repeated localised puncture; Effectively reduce patient's medical expense, save medical manpower and materials, flow process simplifies the operation.
This utility model solves the technical scheme that its technical problem adopted: 1. the thoracentesis needle stylophore is processed by the good soft material of plasticity; Help in the thoracic cavity distortion voluntarily and keep somewhere with long-time, the branched pipe at the about 5cm of distance circle indenting ball place is used for that drawing liquid is bled or injectable drug; 2. the hollow nook closing member is processed by the metallic hard material, and its needle stand end comprises a stop and elasticity anesthesia air bag, helps fixedly nook closing member length and local anesthesia; 3. the stylophore tail end comprises a rubber valve and the length adjuster that is used to regulate the exposed length of nook closing member, and length adjuster contains two stop bayonet sockets, the exposed equal in length of nook closing member in length and the stylophore between two bayonet sockets; 4. design a rotatable soft thin slice at stylophore and branched pipe interface point place, during puncture vertical with skin help gripping inserting needle and be close to skin after puncturing help specialty and apply ointment or plaster fixing.Stylophore that will this novel thoracentesis needle during operator's thoracentesis and nook closing member are formed trocar; Extruding elasticity anesthesia air bag is drawn behind the local anaesthetics infiltration anesthesia successively; Treat that the stylophore syringe needle gets into and regulate length adjuster behind the subcutaneous tissue and make nook closing member bounce back in the stylophore and hold rotatable thin slice and continue inserting needle; Extract nook closing member after getting into the thoracic cavity, the rotation thin slice makes it be close to skin and apply ointment or plaster fixing with specialty.
The beneficial effect of this utility model is that secondary puncture when avoiding conventional thoracentesis is to the injury of patient's body; The syringe needle circle is blunt simultaneously can avoid the lung tissue damage also can keep for a long time with the material softness; Can effectively reduce patient's medical expense, save medical manpower and materials.
