Oropharyngeal cavity flushing type suction tube

Technical Field

The invention relates to the field of medical instruments, in particular to a mouth and throat deep washing type suction tube.

Background

The patients with disturbance of consciousness can not automatically remove sputum, blood, regurgitated gastric contents or other secretions at the mouth, pharynx and laryngeal cavity due to the reduction or loss of the reflex functions of swallowing, cough and the like; and the resistance of the body of the patient is often reduced, the self-cleaning capability of the mucous membrane of the throat cavity is poor, and bacteria planted in the oral cavity and the throat part are easy to cause planting infection, so that respiratory tract infection is caused, and the disease is worsened. At present, a plurality of researches at home and abroad indicate that the strengthening nursing measures for the oropharyngeal cavity have positive significance on preventing the occurrence of pulmonary infection, but in clinical operation, the common operation method and apparatus limit the clearing effect to a certain extent. The conventional sputum suction tube is difficult to wash and suck, and the oral cavity jet type washing of the injector is difficult to accurately wash viscous secretion or sputum scab, so that the suction effect is greatly reduced; meanwhile, the soft sputum suction tube is easy to bend and loop in operation, and the existing patent invention has defects in the design of the radian of the sputum suction tube, so that the sputum suction tube is difficult to deliver to the effective part, thereby influencing the suction effect. Therefore, in response to the above deficiencies, improvements in design are needed to achieve the goal of effective irrigation, aspiration, and removal of oropharyngeal and deep throat secretions.

The prior technical literature is searched to find that:

chinese invention patent application no: 201210535138.2, name: a flushing type sputum suction tube. The invention takes the effect of flushing type sputum suction into consideration, one sputum suction pipe integrates two functions of flushing and sputum suction, an angle is designed at the front end of the sputum suction pipe, the angle is in accordance with the front and back flat physiological structure of the oropharyngeal cavity to a certain extent, and the secretion of the deep throat can be flushed and sucked. However, this patent has the following problems: 1) The opening of the flushing pipe is overlapped with the opening of the suction pipe when flushing and sucking are carried out simultaneously, flushing liquid can be directly sucked back into the suction pipe, and effective flushing cannot be realized; 2) If the washing and the suction are carried out separately, the problem that the aspiration of the washing liquid is neglected to cause aspiration pulmonary edema and the aspiration cannot be carried out in time is solved; 3) The suction tube is not detailed in softness and hardness, the suction tube is bent due to the blockage of tissues such as a tongue body, a tongue root, a faucial pillar of pharynx and palate, and can not be effectively delivered to deep secretions of throat, and if the tube is too hard, mucous membranes can be damaged; 4) The product is shown in an "angled" design, with the apex angle likely to damage the mucosa; 5) The description describes that the direction can be controlled to attract the left and right bronchi in a targeted manner, and the method has the defects that the upper respiratory tract bacteria are brought into the lower respiratory tract to form iatrogenic infection and the operation of placing the upper respiratory tract into the left and right bronchi is not feasible according to the hospital infection management requirements, the clinical sterile operation specifications and the implementation operation difficulty.

Chinese utility model patent application no: 201420464622.5, name: an oral cavity washing type sputum suction tube. This design is washed, is attracted the aspect to the oral cavity, and for two monomer cavity pipes are parallel, bind through "adjustable ring", can carry out the flushing type to trachea cannula patient's oral cavity and inhale phlegm. However, this technique also exists: sucking back the flushing liquid when the flushing and the sucking are carried out simultaneously; the catheter is soft and shielded by tissues in the oral cavity, and cannot reach the suction part effectively. At the same time, the design of its "adjustment ring" presents a risk of falling off, possibly into the trachea or esophagus, increasing the risk to the patient.

Chinese utility model patent application no: 201620449414.7, name: a controllable sputum suction flusher. The device is used for invasive airway patients who use the closed sputum suction tube to suck sputum, and is only used as a flushing tube. The controllable suction device comprises a controllable regulating valve which can control the injection amount of flushing liquid, but the controllable suction device does not have a suction function, cannot be used for flushing and sucking the oropharyngeal cavity, and can increase the risk of aspiration of a patient.

Chinese utility model patent application no: 200920218494.5, name: self-flushing sputum suction tube. When the suction device is used for suction operation, liquid in the connected flushing pipes can be sucked back into the suction guide pipe at the same time, and the suction pipe is cleaned in the inner cavity, so that secretion such as sputum and the like is prevented from blocking the suction guide pipe, but the purpose of flushing and sucking in the oral cavity cannot be achieved.

It is obvious that the current oropharyngeal cavity suction tube generally can not realize flushing type suction to the oropharyngeal cavity and the deep laryngeal cavity or has poor flushing suction effect.
