Description

Portable sputum aspirator

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a portable sputum aspirator.

Background

In daily life, the human body fluid blockage is an emergency with extremely high death rate, and the normal physiological functions of the human body are influenced by the human body fluid blockage (urethra, trachea and the like), so that the characteristics of high casualty rate and high death rate are embodied

Fluid blockage can be medically classified as acute blockage and chronic blockage. Chronic obstruction is the narrowing of the airways due to inflammation, edema, spasm, tumor compression, etc. of the airways. Since the stenosis is gradually formed, it does not pose a threat to the patient's life in a short time. Acute blockages are sudden blockages that are divided into complete blockages that completely interrupt the supply of oxygen and partial blockages that quickly lose life if emergency treatment is not performed. The latter, although still having a certain gas flow, is likely to develop a complete occlusion, and therefore, whether a complete occlusion or an incomplete occlusion, the patient is potentially life-threatening and must immediately take emergency measures to remove foreign matter. Therefore, how to solve the blockage quickly and effectively is a worldwide problem.

Every year, there are not a large number of people who die because of fluid blockages. The harm brought by the drug also touches eyes and surprises. At present, the living environment of people lacks related first-aid articles, so that people can not timely separate patients from dangerous situations, unnecessary casualties are caused, and the emergency measures adopted at present lack timeliness and most of the emergency measures can not be used for rescuing in a targeted manner. If the best treatment time can be grasped and the rescue can be carried out more specifically, the first-aid system can be changed.

The early first-aid measures of the body fluid blockage are very limited, the liquid is only roughly led out, a catheter passes through the oral cavity, the laryngeal opening and the trachea in sequence by opening the airway of a patient to reach the position of a blockage, and negative pressure is generated by an external machine to promote the blockage to be discharged through the catheter.

The sputum aspirator on the market at present can only be equipped in medical health institution to it is bulky to have, requires highly (aseptic, need power etc.) to environmental condition, and the operating procedure is complicated, requires highly to operator professional skill, and shortcomings such as maintenance cost height. The operation efficiency, the emergency time, the safety and the portability of the device are hardly considered.
