Description

Portable sputum aspirator

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a portable sputum aspirator.

Background

The elderly patients lie in bed for a long time, and are easy to cause respiratory tract infection and pneumonia due to weak constitution, cough weakness and thick sputum. Sometimes, phlegm is stuck and cannot be coughed, and symptoms of cyanosis and dyspnea appear, even the life is threatened, so that the method keeps the respiratory tract unobstructed, reduces respiratory tract complications and is very important for the life health of the old.

Traditional sputum suction apparatus is bulky, the price is too expensive, it is generally only used in medical institution, the patient of being not convenient for carries at any time in order to deal with the sputum jam that old patient probably takes place at any time, the unable problem of coughing up of sputum, a simple and easy sputum aspirator has been developed to this kind of problem in the present medical field, however there are some drawbacks in this simple and easy sputum aspirator clinical practice, and the appearance of this drawback leads to simple and easy sputum aspirator can't satisfy medical personnel and old patient's high standard medical care demand, the drawback that now exists traditional simple and easy sputum aspirator carries out as follows:

the utility model provides a, though the problem that the patient can hand-carry is solved to traditional simple and easy sputum aspirator, however traditional simple and easy sputum aspirator is in clinical practice process, its suction is more weak, can't reach and remove thorough purpose with the sputum suction, then the simple and easy sputum aspirator of greatly reduced tradition is to old patient's nursing treatment efficiency, and on this basis, if still use simple and easy sputum aspirator to last the suction to old patient's oral cavity sputum by force, then cause the injury to old patient's oral organ easily on the one hand, on the other hand also very easily increases old patient's uncomfortable sense of health, in addition, the appearance of above-mentioned condition then directly has increased old patient and has used simple and easy sputum aspirator's psychological rejection sense.

The sputum suction nursing work to the old patient later stage will be unfavorable for going on smoothly to the emergence of above-mentioned condition.

Two, the simple and easy sputum aspirator life of tradition is shorter, generally after the sputum aspirator used certain frequency, then directly abandons it usefulness, can't accomplish the purpose of sputum aspirator used cyclically, and the energy-concerving and environment-protective theme of advocating of the emergence of this kind of condition deviates from mutually with the country, has increaseed the loss of financial resources, material resources to a certain extent.

The reason that traditional simple and easy sputum aspirator can't accomplish the recycle is because, the sputum aspirator is not convenient for operating personnel to carry out deep high-efficient washing, disinfection to it, remains from this and then breeds the bacterium easily at the inside sputum of traditional sputum aspirator, if still use the simple and easy sputum aspirator after breeding the bacterium to carry out the sputum suction this moment, then cause cross infection to the patient easily, cause harm to patient's healthy.

Therefore, the development of a new portable sputum aspirator is urgently needed in the medical field.

SUMMERY OF THE UTILITY MODEL

In view of this, an object of the present invention is to provide a portable sputum aspirator to solve the problem that the suction force of the traditional simple sputum aspirator is weak in the prior art, and further solve the problem that the traditional simple sputum aspirator is not convenient for recycling.
