Improved gas pulse instrument for swallowing evaluation

Abstract

The invention discloses an improved gas pulse instrument for swallowing evaluation. A pressure reducing valve is arranged between an air inlet pipe and an air outlet pipe; the end of the air inlet pipe is connected with an oxygen end; the end of the air outlet pipe is arranged at the mouth of a patient to cause swallowing reflex action, and the swallowing function is evaluated by adjusting the airflow; and swallowing reflex can be obtained during accurate pressure, and an air pressure scheme can be made according to pressure evaluation during training. Meanwhile, sealing sleeves and rubber sealing rings are arranged at the side ends of the pressure reducing valve, the whole body, formed after the sealing sleeves and the rubber sealing rings are connected, is in sealing fit with a ventilation opening, and the sealing performance is improved; a ventilation pipe is tightly connected with one end of the air inlet pipe and one end of the air outlet pipe in a sleeving mode, so that the sealing performance with the ventilation pipe is guaranteed. A mounting part is designed and comprises the first suction cup and the second suction cup, and when the instrument needs to be mounted on thewall surface, a connecting rod is connected with a connecting sleeve; and when the instrument needs to be installed on a horizontal plane, a base is connected with a limiting cylinder to facilitate use.

Description

technical field [0001] The invention relates to the field of medical instruments for swallowing function, in particular to an improved gas pulse instrument for evaluating swallowing. Background technique [0002] Dysphagia refers to the process of inability to safely and effectively transport food into the stomach due to damage to the structure and (or) function of organs such as the jaw, lips, tongue, soft palate, throat, and esophagus. The causes of dysphagia mainly include: central system diseases (such as stroke, traumatic brain injury, brain tumor, Parkinson’s disease, etc.); oropharyngeal organic diseases (such as oral cavity and head and neck cancer or vegetation; Pharynx and head and neck radiotherapy or chemotherapy, etc.).

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the swallowing air pulse trainer has a simple structure, and is connected to the rubber ball through a hose. When in use, just align the trachea with the upper jaw and manually press the rubber ball. It is easy to operate, but long-term use increases the labor intensity of medical staff. And can not adjust the size of airflow to evaluate swallowing function

There are also existing ones that connect the hose to oxygen and realize the swallowing assessment through the pressure relief valve, but the seal between the pressure relief valve and the hose is not good, and at the same time, when it needs to be fixed on the wall or horizontal surface during use , the position of the pressure relief valve is not easy to fix. When in use, it is necessary to hold the pressure relief valve by hand, which increases the labor intensity of medical staff
