Description

Multifunctional oropharynx breather pipe suitable for severe neurological patients

Technical Field

The invention relates to the technical field of medical supplies, in particular to a multifunctional oropharyngeal airway suitable for severe neurological patients.

Background

Patients with severe neurological diseases such as cerebrovascular diseases, craniocerebral injuries, craniocerebral tumors and the like are often accompanied by consciousness disorder, glossoptosis and upper respiratory tract obstruction, and an oropharyngeal airway needs to be kept unobstructed. The oropharynx breather pipe is a noninvasive ventilating pipe commonly used in clinic, is generally an oval hollow plastic pipe, is S-shaped in appearance and comprises a flange, a bite block part and a pharynx bending part. The intubation operation is simple and convenient, the airway can be opened rapidly, the temporary artificial airway can be established, the tongue is prevented from falling backwards, the smooth breathing is ensured, and the life is saved.

However, severe neurologic patients are usually consciously obstructed and accompanied with agitation, and not only can not be matched with or even resist the tube placement, but often the tube placement needs to be matched with the tube placement by using a tongue depressor, and the clinical multi-purpose bamboo or wood sheet tongue depressor is easy to be bitten and broken by the agitated patients, so that the tube placement efficiency is influenced, and even the danger that fragments enter the lower part of the throat is possibly caused; there are also tongue depressors made of hard metal materials, but it is easy to damage the patient's teeth, gums, oral cavity, etc. After the catheter is placed, a patient often vomits, swallows or even pulls out the catheter by oneself, so that various adverse effects such as pipeline displacement, lip and tongue injury, airway blockage, respiratory depression and the like are caused.

During the retention period of the oropharyngeal airway, the oropharyngeal portion of a patient is opened, the patient can breathe by opening the mouth, and the nerve severe patient is subjected to multi-row large-dose dehydration treatment, so that the oral cavity and the airway are dry, airway secretion is sticky, even sputum scab is formed, the sputum scab is not easy to cough out or attract, and airway obstruction and respiratory inflammation are further aggravated. The oropharynx of the patient is in an open state and is directly communicated with the outside, dust particles, pollutants and even foreign matters in the air can directly enter the airway, and meanwhile, the secretion of the oropharynx of the patient can directly splash out, so that environmental pollution and cross infection are caused. Nursing operations such as external wet gauze covering of the oral cavity, spraying in the oral cavity and the like are often carried out clinically, the antifouling and wetting effects are difficult to guarantee, and the nursing workload is increased.

Patients with severe neurological symptoms are often accompanied by neurological dysfunction, diminished or even absent swallowing and cough reflexes, large secretions being secreted in the mouth and failing to swallow or cough up. In addition, the severe neurological patients often vomit frequently due to intracranial hypertension, gastric retention and the like; during epileptic seizure, a large amount of secretion gushes out from the oral cavity and the nasal cavity, and the patient can have teeth closed tightly, and can bite flat, bent and crumble the oropharyngeal airway or damage own teeth, or damage the tongue and the oropharyngeal portion due to the displacement of the oropharyngeal airway. If the secretion and vomit can not be cleared in time, the medicine is easy to go down to enter the air passage by mistake, thus causing aspiration, asphyxia and aspiration pneumonia of patients.

Most of patients with severe nerve diseases need treatment operations such as oxygen therapy, atomization, airway humidification, secretion suction and the like, and when cerebrospinal fluid in a cranial cavity leaks out of a nasal cavity due to craniocerebral trauma and skull base fracture of the patient or enters a cranial cavity operation through the nasal cavity, filling in the nasal cavity, secondary blood seepage, intracranial infection and the like, the treatment operations can not be carried out through the nasal cavity and only can be carried out from the oral cavity. Thus, neurologically critical patients also face the problem of requiring the simultaneous oral placement of oropharyngeal airways and the connection of other tubes. But the existing clinical oxygen supply, atomization, airway humidification and continuous suction device and oropharyngeal airway are mostly not matched and cannot be connected, so that the oxygen delivery, atomization, humidification and suction effects are influenced.

In conclusion, an oropharyngeal airway suitable for a patient suffering from severe neurologic diseases is very needed in clinical work, and the oropharyngeal airway is convenient to place a tube and can be firmly fixed without displacement and detachment of the tube; the air passage is sealed, the oral cavity air passage is kept moist, the oropharyngeal secretions and vomit can be conveniently and timely removed and drained, and the oropharyngeal airway and the air passage are kept smooth; simultaneously, the teeth, the lips, the tongues and the oropharynx of the patient are prevented from being damaged; can be connected with the devices for oxygen supply, atomization, air passage humidification, suction and the like in clinical prior art, and ensures the effects of oxygen supply, atomization, humidification and suction.

Disclosure of Invention

In order to solve the problems, the invention discloses a multifunctional oropharynx breather pipe suitable for severe neurological patients, which can be used for severe neurological patients with consciousness disorder, glossoptosis and upper respiratory tract obstruction and requiring to keep an oropharynx breather pipe to keep an airway smooth, is ingenious in design and multiple in function, and can meet various requirements of severe neurological patients. Not only can improve the tube placing efficiency, but also can be firmly fixed, and avoids damaging the teeth, lips, tongues, oropharynx and other skin mucous membranes of a patient; when the oral cavity is sealed, the secretion and vomit can be conveniently and timely sucked, and the smooth air passage of the oropharynx and trachea can be kept; and can be connected with oxygen supply, atomizing, air flue humidifying, the suction device that clinical current, guarantee for oxygen supply, atomizing, humidifying and suction effect, improve clinical air flue management work efficiency, can popularize and apply to other all kinds of severe patients that have similar demand.
