Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a phlegm pipe is inhaled to controllable formula.
Background
A controllable sputum suction tube is a medical instrument used in the process of rescuing and nursing patients in hospitals. Consists of two parts of a joint and a suction pipe. The connector can also be called a negative pressure control device, one end of the connector is connected with a suction tube, and the suction tube can be directly placed into the respiratory tract of a patient and also can be placed into the respiratory tract of the patient through a tracheal cannula or an oropharyngeal airway. The other end of the joint is connected with a negative pressure drainage system. When the negative pressure switch is turned on, the negative pressure suction is started to suck the secretion such as sputum in the respiratory tract of the patient out of the body, so that the respiratory tract of the patient is kept smooth, the infection is avoided, and the life of the patient is saved.
At present, there are many types of sputum aspirators used clinically, such as E-triplet, European and T-type. These types of connectors have a common feature that an operator holds the connector by hand, and presses a thumb against an opening on the side or upper side of the connector when starting to suck sputum after a suction tube portion of a sputum suction tube is fed into a respiratory tract, so that a negative pressure is formed to suck out sputum or secretions. If secretion such as sputum is sticky, the thumb needs to be loosened and then pressed, and the sputum can be loosened and sucked out of the body by repeating a plurality of actions.
Meets the clinical requirement, does not damage the body organs and functions of the patient, and can protect medical care personnel from being polluted to be regarded as good medical equipment. Particularly, the residual negative pressure of the sputum suction tube is required to be not more than 0.33kPa when the thumb is released to control the negative pressure device in China.
The existing controllable sputum suction tubes have defects, such as residual negative pressure of an European controllable sputum suction tube and a T-shaped controllable sputum suction tube can reach the national standard, but sputum can be contaminated on the hands of operators, and the contamination to medical care personnel is caused. The E three-way controllable sputum suction tube can prevent sputum from being stained on the hands of an operator, but residual negative pressure exceeds the standard due to insufficient design, so that bleeding or damage to respiratory mucosa of a patient can be caused.
Therefore, there is a need to provide a new controllable sputum aspirator tube to solve the above-mentioned problems.
