Abstract
The utility model discloses a novel thoracic puncture needle, comprising a hollow puncture needle head. A flexible tube is arranged below the puncture needle head; a pumping connector is arranged below the flexible tube; a medicine-injecting connector for injecting liquid medicine is also arranged on the flexible tube; and a needle core for extending into the puncture needle head is arranged on the medicine-injecting connector. The thoracic puncture needle has simple structure and convenient use.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of novel thoracic-puncture needle.
Background technology
At present, in the treatment hydrothorax, often the instrument that uses adds a mosquito forceps as thoracic-puncture needle, and autoclave sterilization uses repeatedly.And the thoracic-puncture needle that now uses is the single hose structure, this single hose thoracic-puncture needle can satisfy general hydrothorax drawing liquid, but for needs drawing liquid repeatedly, Chong Xi empyema, hemothorax etc. then not too adapt to repeatedly, generally need to extract earlier chest fluid, inject flushing liquor then, extract out more at last, repeatedly puncture, repetitive operation is easy to take place nosocomial infection.And clinically, hydrops is not only arranged in the thoracic cavity, form valve, form tension pneumothorax easily at alveolar or pleura rent, air can only enter in the pleural space with breathing, can not discharge, so that the rising of intrapleural pressure power is very fast, so will prevent to form pneumothorax, usually use the thoracic-puncture needle breast to wear aerofluxus, nosocomial infection takes place in operation so repeatedly easily, for medical personnel's safety is brought hidden danger.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, but disposable puncture carries out injection and drawing liquid simultaneously, can guarantee the novel thoracic-puncture needle of medical personnel's safety.
For solving the problems of the technologies described above, the technical solution of the utility model is: novel thoracic-puncture needle, the piercing needle that comprises hollow, the below of described piercing needle is provided with flexible pipe, the below of described flexible pipe is provided with the extraction interface, also be provided with the injection interface that is used to inject medicinal liquid on the described flexible pipe, described injection seam is provided with the nook closing member that is used to stretch in the described piercing needle.
As a kind of improvement, be provided with adjusting device near described piercing needle place on the described flexible pipe.
Owing to adopted technique scheme, novel thoracic-puncture needle, the piercing needle that comprises hollow, the below of described piercing needle is provided with flexible pipe, the below of described flexible pipe is provided with the extraction interface, described injection seam is provided with the nook closing member that is used to stretch in the described piercing needle, and the external negative pressure device of extraction interface by the flexible pipe below that is connected with piercing needle is provided with can extract hydrops; And, can inject flushing liquor or Drug therapy by the injection interface, and then by inserting nook closing member, extract hydrops, avoid repeated infection, disposable puncture can inject medicine and extraction simultaneously, raises the efficiency, and has also guaranteed medical personnel's safety simultaneously.
Description of drawings
Accompanying drawing is the structural representation of this utility model embodiment.
The specific embodiment
As shown in the figure, novel thoracic-puncture needle, the piercing needle 1 that comprises hollow, below described piercing needle 1, be provided with flexible pipe 2, extraction interface 5 by flexible pipe 2 can be connected with outside pumping device, as utricule or syringe etc.,, can in the thoracic cavity, carry flushing liquor or medicine by the injection interface 6 of flexible pipe 2; Described injection interface 6 places are provided with the nook closing member 3 that is used to stretch in the described piercing needle 1,6 sealings of injection interface can be prevented nosocomial infection by nook closing member 3, guarantee medical personnel's safety, and simple in structure, easy to use.
Be provided with adjusting device 4 near described piercing needle 1 place on the described flexible pipe 2, can regulate the flow that extracts hydrops, use simple, convenient by adjusting device 4.
During use, earlier piercing needle 1 is inserted therapentic part, in the thoracic cavity, pass through to inject in the piercing needle 1 of hollow flushing liquor by injection interface 6 then, flushing liquor injects the back that finishes and inserts nook closing member 3, connect the hydrops that the syringe extraction was washed by extracting interface 5 then, when extracting, can regulate speed and the flow that extracts by adjusting device 4, make the patient comfortable, use simple, convenient.
