Cricopharyngeal muscle expansion training device capable of quantitatively adjusting air pressure

Abstract

The invention discloses a cricopharyngeal muscle expansion training device capable of quantitatively adjusting air pressure. The cricopharyngeal muscle expansion training device comprises a development traction tube, a cricopharyngeal muscle expansion balloon, an air guide tube, an air pressure monitor and a pressing type inflating device, wherein the cricopharyngeal muscle expansion balloon is fixed outside the development traction tube and is arranged close to the lower end of the development traction tube; the middle part and the lower part of the air guide tube are adhered outside the development traction tube, the lower end is connected to the cricopharyngeal muscle dilatation balloon, and the upper end is connected to the first end of the air pressure monitor; and the pressing type inflating device is connected to the second end of the air pressure monitor. When the pressing type inflating device is pressed, the pressing type inflating device can quantitatively inflate the cricopharyngeal muscle expansion balloon, and the air pressure in the cricopharyngeal muscle expansion balloon is displayed through the air pressure monitor. When the pressing type inflating device is loosened, air in the cricopharyngeal muscle expansion balloon can automatically flow back to the pressing type inflating device. The device has the advantages that medical staff can control the inflating amount for inflating the cricopharyngeal muscle expansion balloon in real time and know the inflating air pressure in real time, so that the inflating amount is not too small or too large, and the device is safe and reliable to use.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a cricopharyngeal muscle expansion training device capable of quantitatively adjusting air pressure. Background technique [0002] Dysphagia is a common complication of neurological diseases such as stroke, and cricopharyngeal muscle spasm or achalasia is an important mechanism leading to dysphagia. Inflatable balloon dilation is an effective treatment for cricopharyngeal muscle spasm or achalasia, but The traditional expandable balloon dilation method is to first pull out the gastric tube indwelling in the patient's esophagus, then insert a silicone tube or urinary catheter with an expandable balloon into the patient's throat, and use an inflatable balloon to inflate the expandable balloon. Repeatedly withdraw the expansion tube or repeatedly inflate and contract the expandable balloon to expand the cricopharyngeus muscle of the patient. After the treatment, the gastri...

Problems solved by technology

[0004] Specifically, on the one hand, each time an inflatable balloon is used to inflate the corresponding expandable balloon, the amount of inflation cannot be controlled in real time and the amount of inflation can be known, so that for different patients, cricopharyngeal muscle spasm or achalasia When the severity is different, it is impossible to give the appropriate amount of air to expand the cricopharyngeal muscle. When the amount of air given is too small, the cricopharyngeal muscle cannot be expanded well. When the amount of air given is too large, it will make the The patient's cricopharyngeal muscle will experience expansion and pain, which will cause the patient to feel pain and other discomfort. On the other hand, the silicone tube or urinary catheter with an expandable balloon only has a guiding role, and it can only play a role in traction. The expandable balloon can reach the cricopharyngeus of the patient's throat, but cannot be used directly as a gastric tube. The specific reasons are: its length is too short to extend into the patient's esophagus or stomach, and the expandable balloon set on it In order to be adjacent to its lower end, the corresponding expandable balloon is placed in the cricopharyngeal muscle of the patient's throat, so that the lower end of the corresponding silicone tube or catheter can only be a little below the cricopharyngeal muscle of the patient's throat. After it is used, it needs to be pulled out from the patient's throat and a gastric tube is reinserted into the patient. In this way, the cost of materials will be increased and resources will be wasted, and the workload of medical staff will increase, resulting in increased labor costs and increased patient cooperation. The number of times leading to increased catheterization pain
