Description

Cushion for relieving gastroesophageal reflux

Technical Field

The invention belongs to the field of postoperative care products for esophagus cancer and cardiac cancer, and particularly relates to a pad for relieving gastroesophageal reflux.

Background

The esophagus cancer patient is positioned in the esophagus due to the disease, but the esophagus does not have a substitute at present, so the stomach is made into a long tubular shape to replace the esophagus in the operation, the cardia is cut in the operation, the cardia is also cut in the operation process due to the fact that the cardia is diseased, and the stomach is made into a long tubular shape to replace part of the esophagus. Because the cardia has the function of automatically adjusting and contracting, the gastric acid reflux is prevented, and the cardia is cut off after the esophageal cancer and cardia cancer patients are subjected to operation, so the gastric acid reflux is easy to occur after the operation, if the patients lie down and the long-term acid reflux is caused, part of esophageal mucosa is burnt, the esophagitis is caused, and even part of the patients can cause the aspiration pneumonia seriously due to the reflux. Therefore, patients with esophageal cancer need to be in a semi-reclining position for life after surgery.

Currently, commercially available gastroesophageal reflux relief pads are generally soft pads 101 as shown in fig. 1, which comprise a headrest portion 102, a shoulder pad 103, a waist support portion 104 and a hip block portion 105, and can be used for a postoperative patient to lie on the back. However, the filler in this cushion 101 adopts a monoblock sponge or latex, can not adjust according to patient's different neck characteristics, leads to the patient when the specification requirement that the demand is between different models, and the cushion can't give the patient good experience effect.

Another adjustable cushion is shown in fig. 2, and comprises a bottom frame 201 and clamping teeth 202 sequentially arranged on the bottom frame in the front-back direction, a bracket 203 capable of pitching and swinging is hinged on the front side of the bottom frame 201, a claw 204 capable of being buckled on the clamping teeth is hinged in the middle of the bracket 203, and a cushion 205 is fixed above the bracket 203. However, the adjustment mode is a pitching and swinging adjustment mode, the adjustment freedom degree is single, and the adjustment mode cannot be adapted to the human body adjustment variable, so that the experience effect of a patient is poor.
