Description

Technical Field

[0001] The utility model belongs to the technical field of gastroscopy, in particular to a gastroscopy auxiliary device. Background Art

[0002] Gastroscopy is a procedure that uses a thin, soft tube to be inserted into the stomach. Doctors can directly observe lesions in the esophagus, stomach, and duodenum, especially tiny lesions. During gastroscopy, auxiliary devices are required, which usually insert the gastroscope tube into the mouth and esophagus.

[0003] Existing mouth openers for gastroscopy usually require the patient to bite the mouth opener to complete the opening of the patient's mouth. When the gastroscopy tube passes through the fixator to examine the patient, when further inspection or treatment of the lesion is required, the fixator cannot position the gastroscopy tube, which brings inconvenience to the doctor's work. In addition, when the mouth is open for a long time, a large amount of saliva will flow out of the mouth, causing pollution to equipment, beds, clothes, etc. Therefore, it is of great significance to study a new gastroscopy auxiliary device to solve the above problems.

[0025] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0026] like Figure 1-5As shown, the utility model provides a technical solution: a gastroscopy auxiliary device, comprising a mask 1, wherein the upper and lower sides of the mask 1 are fixedly connected with a headband 2, and the headband 2 is worn on the head, and since the headband 2 has elastic tightening property, the headband 2 can fix the mask 1 to prevent the mask 1 from falling off, and a water absorption structure 4 is arranged inside the mask 1, and the water absorption structure 4 comprises two Velcros 42, and the two Velcros 42 are respectively fixed inside the mask 1 and on a sponge layer 41, and the sponge layer 41 can be fixed in the mask 1 by bonding the two Velcros 42 to each other, and the sponge layer 41 can absorb the saliva produced by the patient to prevent the problem of saliva leakage and contamination of clothes and beds, and the two Velcros 42 are bonded to each other, and the two Velcros 42 are bonded to each other. The sponge layer 41 is fixed by bonding the stickers 42, and the sponge layer 41 can be removed by separating the two Velcro stickers 42. The sponge layer 41 is arranged in the mask 1, and a mouth opener 3 is fixedly installed in the middle of the mask 1. The mouth opener 3 can be convenient for the patient to bite, so that the patient's mouth can be opened, avoiding the problem that the patient's mouth is difficult to insert the gastroscope tube. The inside of the mouth opener 3 is fixedly connected to a cylindrical airbag 5, and the center of the cylindrical airbag 5 is an opening, so that the gastroscope tube can pass smoothly. Both sides of the cylindrical airbag 5 are connected to an inflatable structure 6, and the inflatable structure 6 includes an elastic airbag 61. Through the reset property of the elastic airbag 61, the internal gas of the cylindrical airbag 5 can be smoothly extracted through the three-way pipe 71, and one end of the elastic airbag 61 is connected to a one-way valve 62 The one-way valve 62 can keep the gas inside the elastic airbag 61 from entering the cylindrical airbag 5 and prevent gas reflux. One end of the one-way valve 62 passes through the mouth opener 3 and is connected to the cylindrical airbag 5. When the gastroscope tube needs to be positioned, such as when the lesion location or biopsy operation is performed, the elastic airbag 61 can be pressed to press the gas inside the elastic airbag 61 into the cylindrical airbag 5 through the one-way valve 62, so that the cylindrical airbag 5 expands and can fit tightly on the gastroscope tube and press against the gastroscope tube, so that the cylindrical airbag 5 presses against the gastroscope tube to complete the fixation of the gastroscope tube, thereby preventing the gastroscope tube from being displaced, thereby facilitating the doctor's examination of the patient. The inflatable structure 6 passes through the mouth opener 3 and is fixed on the mouth opener 3. The two inflatable structures 6 are also connected with a three-way structure 7. The three-way structure The structure 7 includes a three-way pipe 71, through which the cylindrical airbag 5 and the elastic airbag 61 can be connected to ensure the flow of gas. The two ends of the three-way pipe 71 are respectively connected to the two elastic airbags 61. A valve 72 is provided on the three-way pipe 71. The opening and closing of the pipeline of the three-way pipe 71 can be controlled by the valve 72. Opening the three-way pipe 71 can ensure smooth reflux of gas. The other end of the three-way pipe 71 passes through the mouth opener 3 and is connected to the top of the cylindrical airbag 5. By rotating the valve 72, the three-way pipe 71 is opened and the pipeline of the cylindrical airbag 5 is elastically reset, and the gas inside the cylindrical airbag 5 is extracted through the three-way pipe 71, so as to facilitate the extraction of the gastroscope tube. The three-way structure 7 penetrates from the top of the mouth opener 3 and is connected to the cylindrical airbag 5.

[0027] The working principle of the utility model is:

[0028] During the examination, the mask 1 can be worn on the patient's mouth and fixed on the patient's head by tightening the headband 2, and then the gastroscope tube can be inserted through the cylindrical airbag 5 to extend the gastroscope tube into the patient's mouth and into the patient's stomach. When the gastroscope tube needs to be positioned, for example, when the lesion is found or a biopsy is performed, the elastic airbag 61 can be pressed to allow the elastic airbag 61 to pass the internal gas into the cylindrical airbag 5 through the one-way valve 62, so that the cylindrical airbag 5 expands to press the gastroscope tube tightly to prevent the gastroscope tube from being displaced. At this time, it is convenient for the doctor to perform positioning inspection or biopsy on the patient.
