Description
Technical field
The present invention relates to a kind of Medical pollution-proof thoracocentesis devices, belong to medical instruments field.
Background technology
Hydropericardium, pleural effusion are clinical medicine common diseases.Pleural effusion is that the liquid of pleural surface interstitial is excessive
It leaks out or oozes out and put aside the liquid in pleural cavity, be commonly called as hydrothorax.Pleural effusion is not a kind of disease, but systemic disease
Or a kind of consequence of pleural diseases.Its symptom includes pleura pectoralgia and shortness of breath；Therefore the extraction of pleural effusion can mitigate liquid
Compressing of the body to lung tissue is answered lung tissue and is opened, alleviate the symptoms such as the expiratory dyspnea of patient.In the wild in the case of first aid, such as
The body of fruit patient is inconvenient to move the extraction for needing to carry out pleural effusion under complex environment in the wild, is extracting thoracic cavity product
Before liquid, will usually carry out disinfection to thoracic cavity epidermis operation, but dust storm is larger sometimes for wild environment, and the epidermis after disinfection holds very much
It is vulnerable to pollution.And after pneumothorax puncture needle is taken out, puncture needle has longer time exposure in the air in field, making
Into the pollution of puncture needle, and since wild environment is complex, easily there is pollutant from puncture hole in piercing process
Place enters patient's body tissue, be easy to cause puncture infection.
The content of the invention
For it is existing in the prior art " before pleural effusion is extracted, will usually carry out disinfection to thoracic cavity epidermis operation, but
It is that dust storm is larger sometimes for wild environment, the epidermis after disinfection is highly susceptible to pollute.And after pneumothorax puncture needle is taken out, wear
Pricker has longer time exposure in the air in field, causing the pollution of puncture needle " deficiency, the present invention provides a kind of
Medical pollution-proof thoracocentesis device.
In order to solve the above technical problems, the present invention adopts the technical scheme that, a kind of Medical pollution-proof thoracentesis dress
It puts, including outer sleeve and internal puncture needle, outer sleeve is hollow pipe closed at both ends；The needle point of the internal puncture needle is worn
Barbed end is front end, and the rear end of internal puncture needle passes through the rear end face of outer sleeve and is arranged at outside outer sleeve, internal puncture needle
