Abstract
The utility model relates to a miniature medical negative-pressure sputum aspirator which is a medical appliance capable of continuously generating the negative pressure under the actions of a negative-pressure air cylinder and a non-return valve. The utility model can be used for aspirating sputum when critically ill patients are rescued by clinicians in each medical section and can also be used when the uterine cavity of a gynecological suspected impregnate patient is checked or is sampled for biopsy. The negative pressure can reach from 400 mmHg to 600 mmHg. The utility model has the advantages of small size, light weight, and no power supply. The utility model which can be carried about by a doctor is prepared to be applied at any time.
Description
This miniature negative pressure sputum aspirator is the medical apparatus and instruments that belongs to a kind of utility model.
At present, when rescuing critically ill patient suction expectorant, employed suction expectorant method has three kinds:
The one, connect sputum aspirator tube with syringe and inhale expectorant, delay certain rescue time because of it can not produce negative pressure continuously, and feel inconvenience in use deeply.
The 2nd, inhaling " appearance expectorant " glass tubing of expectorant sebific duct indirect, one end of sebific duct inserts in patient's trachea during use, and the other end is contained in doctor's the oral cavity, inhales expectorant by the sucking action in oral cavity, does like this not meet the health care principle.
The 3rd, electric sputum aspirator because of volume is big, must have power-supply device again, when rescuing critically ill patient, electric sputum aspirator must be moved on to patient's head of a bed usefulness, and real is inconvenience, and particularly under the condition of non-transformer equipment or power failure, the doctor just feels not have plan.
Miniature negative pressure sputum aspirator can be removed the various shortcomings in the above-mentioned suction expectorant method.Little, in light weight because of its volume, can produce the advantage of negative pressure continuously without power supply, the doctor can carry, in order to using at any time.
Miniature sputum aspirator operation principle is very simple, and 4. 2. the pull bar of twitch negative pressure inflator because of 3. pull bar top leather cup is inverted, and can be extracted out by check (non-return) valve holding the 8. interior air of liquid bottle, thereby produced negative pressure in all connection scopes of sputum aspirator.When promoting tie-bar, check (non-return) valve can be controlled air automatically effectively and reflux, and air can be discharged along the leather cup periphery in the inflator.Twitch inflator so repeatedly and 1. can produce negative pressure continuously, to reach the effect of inhaling expectorant.
This miniature negative pressure sputum aspirator also can be used when the doubtful gestation of gynecologic patient is checked uterine cavity or sampling biopsy, and because of the suction pipe head is airtight in uterine cavity, when twitching inflator generation negative pressure, the negative pressure indicator can be pointed out negative pressure quantity, the minimum 400～600mmHg that reaches.The doctor is the negative pressure degree as required, looks the numeral of negative pressure indicator indication, regulates the negative pressure quantity of required usefulness arbitrarily.
