Example 1

Please refer to Fig. 1 and Fig. 2, the present embodiment provides an esophagus dilator 001, which includes a main pipe 100 and a protective sheath 110 sleeved on the main pipe 100, one end of the protective sheath 110 is connected to the end of the main pipe 100, the main pipe The outer wall of 100 is provided with an expandable first air bag 120, and the first air bag 120 is located between the main pipe 100 and the protective cover 110; The outer wall of the outer wall is provided with tooth engaging grooves 141 arranged oppositely, and the two ends of the limiting cylinder 140 are respectively provided with protrusions 142 corresponding to the tooth engaging grooves 141. 140 is arranged in the axial direction, and an expandable second airbag 143 is provided on the edge of the limit tube 140 near the end, and the two sides of the limit tube 140 are respectively connected with fixing belts 144 . The esophageal dilator 001 also includes a branch tube 130 connected to the front end of the main tube 100 , and a pluggable sealing plug 131 is provided in the branch tube 130 . The esophageal dilator 001 also includes a support bar 250 that can move along the inside of the main tube 100 , and the outer wall of the support bar 250 is provided with a guide groove 251 extending along its length. Specifically, in this embodiment, the first airbag 120 and the second airbag 143 are respectively connected with corresponding inflation tubes.

The esophageal dilator 001 provided in this embodiment includes a main tube 100 and a protective sheath 110 for protecting the first air bag 120 provided on the outer wall of the main tube 100. When using the esophageal dilator 001, the front end of the main tube 100 is held and The end is inserted into the patient's esophagus, so that the first balloon 120 provided on the outer wall of the main tube 100 is located at the esophagus to be expanded, and then the end of the protective sheath 110 that is not connected to the main tube 100 is wrapped around the first balloon 120 and the main tube 100, and then protrudes out of the patient's mouth , at this time, the inflation tube can be used to inflate the first air bag 120. After the first air bag 120 is inflated, it pushes the protective sleeve wrapped around it to expand, and pushes the inner wall of the patient's esophagus to expand outward, thereby achieving the effect of expanding the esophagus. The process of inflation and expansion of the first airbag 120 is relatively slow, so it will not bring greater discomfort to the patient's esophagus, and since the protective sheath 110 is provided between the first airbag 120 and the inner wall of the patient's esophagus, when the first airbag 120 When the pressure is too large and damaged, the gas leaked from the first airbag 120 will also be blocked by the protective cover 110, and will be discharged to the outside of the patient's oral cavity through the end of the protective cover 110 that is not connected to the main pipe 100, so as to prevent the first airbag 120 from being overpressurized. When the leaked gas causes damage to the patient's esophagus, the use safety of the esophageal dilator 001 is greatly improved.

The esophageal dilator 001 also includes a branch tube 130 connected to the main tube 100. When the esophagus dilator 001 is used to dilate the patient's esophagus, the branch tube 130 can be used to take medicine, feed and remove sputum for the patient. When the medical staff uses the esophagus dilator 001 After dilating the patient's esophagus, the medicinal liquid or liquid food can be introduced into the main tube 100 through the branch tube 130 and then passed into the patient's stomach through the esophagus. In addition, the medical staff can also extend the suction tube into the patient through the branch tube 130 and the main tube 100 At the esophagus of the patient, the sputum accumulated in the patient's esophagus is sucked out through the sputum suction tube. In addition, in order to avoid dust entering the branch tube 130 and being polluted, the medical staff can use a sealing plug 131 to seal the branch tube 130, so that the branch tube 130 can be well cleaned. Protect.

In addition, the esophageal dilator 001 also includes a support bar 250 that can move along the inside of the main pipe 100. The outer wall of the support bar 250 is provided with a guide groove 251 extending along its length. , the support bar can be

250 is stuffed into the main tube 100 for support, preventing the first air bag 120 from expanding and squeezing the main tube 100 after inflating, preventing the medicinal liquid and liquid food from entering the patient's esophagus from the branch tube 130 through the main tube 100, and the guide groove 251 provided on the outer wall of the support bar 250 The medical solution and liquid food flowing into the main tube 100 through the branch tube 130 can be guided to flow into the patient's esophagus.

When the medical personnel set the esophageal dilator 001 in the patient's esophagus, in order to avoid damage to the main tube 100 or the oral cavity when the teeth are closed, the patient needs to keep the mouth open for a long time, which seriously affects the patient's experience. The problem is that the front end of the main tube 100 is covered with a movable limiting cylinder 140, and the outer wall of the limiting cylinder 140 is provided with a tooth engagement groove 141 arranged oppositely.

The dental clamping groove 141 and the two corresponding protrusions 142 are arranged along the axial direction of the cylinder 140. When the patient's teeth are fixed on the dental clamps When it is in the groove 141, the protrusions 142 at both ends of the tooth engaging groove 141 can further restrict the patient's teeth to prevent the patient's teeth from sliding.

After the medical personnel insert the main tube 100 into the patient's esophagus to dilate the esophagus, although the patient can engage the upper and lower teeth in the teeth engaging grooves 141 provided on the outer wall of the limiting cylinder 140 to avoid fatigue from opening the mouth for a long time, the main tube 100 However, the inside and outside of the patient’s oral cavity cannot be completely closed. In order to prevent the dust and bacteria in the external air from entering the patient’s oral cavity, a second expandable airbag 143 is provided on the edge of the limiting cylinder 140 near the end. The medical staff can Inflate the second airbag 143 through the inflation tube, and make the second airbag 143 inflated to fit the patient's face, thereby forming a closed space between the limiting cylinder 140, the second airbag 143 and the patient's face, and passing through the main tube 100 Deliver air to the patient. In order to improve the stability of the connection between the esophageal dilator 001 and the patient, fixing straps 144 are respectively connected to both sides of the limiting cylinder 140 , and the medical personnel can fix the esophageal dilator 001 on the patient's head through the fixing straps 144 .
