Self-regulation type dysphagia balloon dilatation pressure control device and control method thereof

Abstract

The invention relates to the technical field of machines. A self-regulation type dysphagia balloon dilatation pressure control device comprises a water inlet pipeline, a water storage groove, an automatic water draining pipeline system and a water collecting groove; a water outlet of the water inlet pipeline exactly faces the water storage groove; an outlet is formed in the bottom of the water storage groove, a valve is arranged at the outlet, and a joint used for being connected with a dilatation pipe provided with a balloon is arranged at the outlet; the automatic water draining pipeline system is erected on the water storage groove and comprises a U-shaped pipeline in an inverted U shape, a circuitous pipeline, a tee joint and a water draining pipe; three joints of the tee joint are respectively connected with the water outlet of the U-shaped pipeline, the water outlet end of the circuitous pipeline and the water inlet end of the water outlet pipeline. According to the device, the outlet of the water storage groove is directly connected with the dilatation pipe, therefore water pressure in the balloon is controlled by the liquid level of the water storage groove, and through thestructural arrangement of the automatic water draining pipeline, the liquid level in the water storage groove can always be in a set range conveniently.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a balloon pressure control system. Background technique [0002] Swallowing dysfunction is a common complication of neurological diseases, and cricopharyngeal muscle achalasia caused by stroke is the most common cause of swallowing dysfunction. In recent years, the incidence of stroke has continued to increase in my country, with more than 2 million new cases each year, with an average of one new stroke every 15 seconds. The incidence of dysphagia in stroke patients is 30-50%, and aspiration occurs The rate is 40-70%. [0003] At present, balloon dilatation is often used in the treatment of cricopharyngeal muscle achalasia at home and abroad. The device used in balloon dilation originated from a double-lumen catheter. Water balloons are injected into the balloon cavity to expand the balloon. The size and pressure are related to the amount of water injected. The main process...

AI Technical Summary

Problems solved by technology

The degree of achalasia in each patient with cricopharyngeus achalasia may not be the same, and the degree of achalasia in the same patient before each dilatation treatment may also be different (the cricopharyngeus achalasia gradually improved after dilation treatment), each time The dilatation treatment needs to adjust the amount of water injected into the balloon several times to obtain the appropriate pressure, which is not only time-consuming and laborious, but also difficult to control the pressure, and it also brings more discomfort and damage to the pharyngeal mucosa of the patient.
