[0002] The use of painless gastroscopy improves the comfort of patients and facilitates gastroscopy operation. In general, the user uses a special mask for gastroscopy, uses the oxygen supply pipe on the mask to supply normal pressure oxygen to the patient, and the patient retains spontaneous breathing. The gastroscopy mask has a through hole specially for the gastroscopy, and the hole diameter is larger than the outer diameter of the gastroscopy, so that the gastroscopy can be inserted and withdrawn. However, when respiratory depression occurs, the mask cannot be sealed, and a positive pressure oxygen input environment cannot be established, and the patient cannot be given first aid. At this time, the gastroscopy needs to be removed from the patient's digestive tract and oral cavity, and then the gastroscopy through hole is blocked, and the patient is given pressurized oxygen.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0029] A specific embodiment of this utility model is as follows: Figure 1 As shown, a mask for painless gastroscopy (hereinafter referred to as the mask) is disclosed, including a mask body 1, a strap 2, a gastroscopy balloon 3, an inflation seat 4, and an inflation mechanism. The strap 2, the gastroscopy balloon 3, and the inflation seat 4 are all set on the mask body 1. The strap 2 is used to connect the mask body 1 to the patient's face. The mask body 1 is used to cover the patient's mouth and nose. A gastroscopy through-hole is opened on the mask body 1. The gastroscopy balloon 3 is set on the side wall of the gastroscopy through-hole. The inflation mechanism can be connected to the inflation seat 4 and can inflate the gastroscopy balloon 3, so that the gastroscopy balloon 3 connects to the outer wall of the gastroscopy and blocks the gastroscopy through-hole. In the event of respiratory depression, the mask can be sealed without removing the gastroscopy, establishing a positive pressure oxygen input environment for emergency treatment of the patient, which greatly saves emergency treatment time.

[0030] Preferably, the endoscope balloon 3 is a ring-shaped elastic balloon, and the outer wall of the endoscope balloon 3 is connected to the inner wall of the endoscope orifice. After inflation, the inner diameter of the endoscope balloon 3 can become smaller, and the inner wall of the endoscope balloon 3 can connect with the endoscope, thereby blocking the endoscope orifice and preventing oxygen from escaping from the endoscope orifice to the cover 1, thus sealing the cover 1.

[0031] Preferably, such as Figure 2 As shown, the mask in this embodiment also includes an oxygen delivery tube 5. The oxygen delivery tube 5 includes a tube body 51 and a locking protrusion 52. The locking protrusion 52 is disposed on the outer wall of the tube body 51. One end of the tube body 51 can be connected to the inflation seat 4, and the other end of the tube body 51 can be connected to the ventilator, thereby supplying oxygen to the mask body 1. The locking protrusion 52 can be connected to the inflation seat 4 to prevent the tube body 51 from detaching from the inflation seat 4.

[0032] Preferably, such as Figure 3 As shown, the inflation seat 4 includes a seat body 21, an oxygen port 22, and a locking flange 23. The seat body 21 is connected to the cover body 1. Both the oxygen port 22 and the locking flange 23 are disposed on the seat body 21, and a locking groove is formed between the locking flange 23 and the seat body 21. The tube body 51 can be connected to the seat body 21 and supply oxygen to the cover body 1 through the oxygen port 22. The locking protrusion 52 can be connected to the locking groove, and the locking flange 23 can prevent the locking protrusion 52 from axially disengaging from the locking groove, thereby preventing the tube body 51 from disengaging from the inflation seat 4.

[0033] Preferably, such as Figure 1 As shown, to quickly inflate the endoscope balloon 3, the inflation base 4 also includes an inflation port 24, a one-way valve (not shown in the figure), and an air supply tube (not shown in the figure). The inflation port 24 is located on the base 21, the one-way valve is located on the inflation port 24, one end of the air supply tube is connected to the one-way valve, and the other end of the air supply tube is connected to the endoscope balloon 3. The user can connect the inflation mechanism to the inflation port 24 and inflate the endoscope balloon 3 through the air supply tube, thereby sealing the cover 1. The gas from the inflation mechanism can enter the air supply tube through the one-way valve. The one-way valve prevents gas from flowing out of the air supply tube, thereby preventing gas from flowing out of the endoscope balloon 3, ensuring that the endoscope balloon 3 is always inflated, and ensuring the sealing effect of the endoscope orifice.

[0034] Preferably, such as Figure 1 As shown, to improve the airtightness between the mask body 1 and the patient's face, the mask in this embodiment also includes a facial airbag 6. The facial airbag 6 is disposed at the opening of the mask body 1 and is an annular airbag. The facial airbag 6 is connected to an air supply tube, and the gas from the inflation mechanism can enter the facial airbag 6 through the air supply tube. The facial airbag 6 can inflate and expand, thereby sealing the gap between the opening of the mask body 1 and the patient's face, preventing oxygen from leaking out of the gap.

[0035] Preferably, such as Figure 3As shown, the inflation seat 4 further comprises a deflation valve 25 arranged on the seat body 21. When the deflation valve 25 is opened, the gas in the gastroscope air bag 3 and the face air bag 6 can be discharged through the deflation valve 25, the inner side wall of the gastroscope air bag 3 is separated from the gastroscope, thereby releasing the blockage of the gastroscope through hole.

[0036] In some alternative embodiments, the inflation mechanism is a syringe which can be connected with the inflation interface 24 and inflate the inflation interface 24.

[0037] In some alternative embodiments, as shown, Figure 1 The inflation mechanism is a balloon 7 and an air pipe 8, one end of the air pipe 8 can be connected with the inflation interface 24, and the other end of the air pipe 8 is connected with the balloon 7. The user presses the balloon 7 to inflate the inflation interface 24.

[0038] Compared with the prior art, the inflation mechanism of the mask provided by the embodiment can be connected with the inflation seat 4 and inflate the gastroscope air bag 3, so that the gastroscope air bag 3 is connected with the outer wall of the gastroscope to block the gastroscope through hole. When respiratory depression occurs, the mask can be sealed without removing the gastroscope, a positive pressure oxygen input environment is established, and emergency treatment is performed on the patient, which greatly saves the emergency time. The face air bag 6 is connected with the air pipe, the gas of the inflation mechanism can enter the face air bag 6 through the air pipe, and the face air bag 6 can be inflated to block the gap between the opening of the mask body 1 and the face of the patient, thereby preventing the oxygen from leaking from the gap.

[0039] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
