Description
Technical Field
The utility model relates to the technical field of medical care devices, especially, relate to a disposable prevents spouting closed phlegm pipe.
Background
Sputum suction is an important emergency nursing technology, and refers to a method for sucking secretions in a respiratory tract out through an oral cavity, a nasal cavity and an artificial airway (tracheotomy) so as to keep the respiratory tract smooth and prevent complications such as aspiration pneumonia, atelectasis, asphyxia and the like. It is an invasive operation that utilizes the principle of negative pressure suction and connects the catheter to suck out sputum.
At present, many clinical lung disease patients often need tracheotomy, which is convenient for discharging sputum and secretion, improves ventilation and corrects anoxia. During the treatment period of a tracheotomy patient, sputum suction nursing is very important, a disposable sputum suction tube is a common device, and the existing disposable sputum suction tube is generally of a common tubular structure. However, the following problems remain in clinical practice: 1. in order to prevent the pollution problem of the sputum suction tube, when the clinical sputum suction nursing operation is carried out, a nurse can use a pair of rubber gloves, and some patients can suck sputum frequently, which causes great consumption. Some sputum suction operations use tweezers, but the sputum suction operations are relatively inconvenient, so that the sputum suction nursing quality is influenced. 2. During the sputum suction operation, the patient is often choked to cough due to the stimulation of trachea, sputum and secretion of the airway are often sprayed out along with the patient, splashing pollution is caused, the pollution of medical environment is caused, and the hidden danger of nosocomial infection is also caused. There is also a closed sputum aspirator, but is mostly used for patients using a respirator or trachea cannula, and the structure is more complicated, the cost is higher, and the closed sputum aspirator is less used for general patients with tracheotomy.
In addition, in the sputum suction process, if the patient has cough, the operation needs to be suspended, the sputum suction tube is drawn out, and the patient continues to suck the sputum after the sputum in the deep part is coughed out. However, since the conventional sputum aspirator does not have a function of preventing the reverse flow of sputum, the sputum remaining in the sputum aspirator easily flows back into the respiratory tract of the patient when the sputum is withdrawn.
