DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0032] The diameter of a transoral endoscope is generally about 1.2 cm, the size of the oral opening is generally between 3.5-5.5 cm for adults, and between 2.5-7 cm for children. Therefore, when designing the product, the diameter of the support tube 300 is generally set to about 2 cm, which is sufficient for use; when the opening is 2 cm, the oral cavity is generally open.

[0033] Embodiment 1:

[0034] Based on the general clinical oxygen mask, a new optimized design is carried out, such as Figure 1 , Figure 2 , Figure 3 As shown, the oxygen mask of this embodiment is composed of a first shell 100 and a second shell 200 to form a hollow shell. The second shell 200 is connected to a connecting surface 120 located at the center of the first shell 100. The second shell 200 is provided with a plurality of through holes 210. An oxygen port 110 is provided on the lower side of the first shell. The oxygen port 110 is connected to an oxygen supply device through a cannula, thereby forming an oxygen input from the first shell 100 and oxygen overflowing from the plurality of through holes 210 on the second shell 200. When the oxygen mask is worn on the head and fixed, the overflowed oxygen will diffuse in the oxygen mask for the patient to breathe.

[0035] like Figure 3 As shown, there is a sealing member 400 that penetrates the connecting surface 120 and is fixed on the connecting surface 120. The sealing member 400 is in a "trumpet shape" and is formed by connecting a first opening 410 and a second opening 420. The first opening 410 is opened and fixed on the connecting surface 120. The first opening 410 and the second opening 420 are similar elliptical shapes, and the size of the second opening 420 is larger than that of the first opening 410. The second opening 420 wraps the patient's mouth. After the oxygen mask is worn, the second opening 420 wraps the mouth in the sealing member 400.

[0036] like Figure 1 and Figure 2 As shown, the support cannula 300 is inserted into the oral cavity through the sealing member 400. The shape of the support cannula 300 is circular or oval, and the diameter or the size of the secondary axis is 2 cm. The interior is a hollow structure for the entry of endoscopic instruments. There is a circle of gripping ring 310 on the outside of the support cannula 300. The gripping ring 310 is used to take and place the support cannula 300. After the support cannula 300 is fixed in the oral cavity, it is located on the surface of the connecting surface 120. The other side of the support cannula 300 is placed in the patient's oral cavity to support the patient's oral cavity. The length of the support cannula 300 is greater than the depth of the oxygen mask (the distance from the connecting surface 120 to the right side of the oxygen mask) by 2-5 cm. This size is sufficient for the support cannula 300 to open the oral cavity, thereby establishing a channel for the endoscope to enter and exit inside the support cannula 300.

[0037] As a preferred embodiment, there is an insert block on the back of the holding ring 310, and the size of the insert block is: the shape and size from the outer surface of the supporting tube 300 to the inner surface of the sealing member 400 (from the first opening 410 inward). The supporting tube 300 can be firmly fixed in the sealing member 400 through the insert block, and the fixing depth of the insert block is 0.5-3cm.

[0038] The support cannula 300 is detachably mounted and is preferably made of a transparent material. When in use, the oxygen mask is first fixed to the nose and mouth by a strap, the periphery of the oxygen mask is fitted on the skin of the face, and the seal 400 is fixed around the oral cavity. At this time, the support cannula 300 is inserted into the oral cavity through the seal 400 to open the oral cavity. Thus, a sealed space is constructed within the second shell 200 and outside the seal 400, and the oxygen in the space is inhaled through the nose. The oxygen port 110 is set at the lower end rather than the upper side, which is conducive to the routing of the oxygen pipe and also conducive to providing a neater operating space for the operation. The oxygen is delivered through several through holes 210, and the advantage is that the oxygen input is more stable and uniform. If necessary, a catheter can also be connected at the position of the through hole, and inserted into the nasal cavity through the catheter to achieve accurate oxygen delivery.

[0039] In this embodiment, the shape of the oxygen mask and the fixing method of the oxygen mask are all existing contents in the prior art and will not be repeated here.

[0040] Embodiment 2:

[0041] On the basis of Example 1, in order to enhance the sealing effect and the comfort of the oral skin, Figure 4 As shown, a sealing ring 430 is extended and fixed on the outer side of the second opening 420 of the sealing member 400. The width of the sealing ring 430 is 0.3-2 cm, and the sealing ring 430 is in firmer contact with the skin around the oral cavity, providing better comfort.

[0042] Preferably, if Figure 5 As shown, the upper side of the sealing ring 430 is recessed inward to form a recessed portion 440, and the recessed portion 440 is in a downward curved shape. When the sealing ring 430 is placed around the oral cavity, the upper recessed portion 440 fully exposes the area below the nasal cavity, providing space for the patient's smooth oxygen inhalation.

[0043] Embodiment 3:

[0044] On the basis of Example 1, considering the demand for size adjustment in the background art, the size adjustment can be achieved through the adjustment member 500 on the basis of the technical solution of the utility model, such as Figure 6 As shown, the shape of the adjusting member 500 is also circular or elliptical, and its diameter and short axis are the same as the outer diameter of the supporting cannula 300 , and the adjusting member 500 is fixed by wrapping it on the outer surface of the supporting cannula 300 .

[0045] The adjusting member 500 is supported by a silicone material, which is more comfortable in the oral cavity. The width of the adjusting member 400 is 0.5-1 cm, and the upper and lower surfaces are concave inward to form a curved surface. Usually, the adjusting member 500 is used as an occlusal member, and the teeth are placed on the upper and lower surfaces of the adjusting member 500. The front and rear positions of the adjusting member 500 are adjustable to suit different patients. During use, the teeth bite on the adjusting member, which feels better than biting on the outer surface of the supporting cannula 300.

[0046] In addition to the adjustable front and rear positions, the upper and lower heights of the adjusting member 500 can also be adjusted. By selecting adjusting members 500 of different heights to adapt to different patients, it is different from the method of personalized adjustment of complex mechanical adjustment mechanisms and is more in line with clinical reality. Oxygen masks are generally disposable in clinical practice. Therefore, by configuring adjusting members 500 of different heights and sizes, it is sufficient to meet clinical use and has a lower overall cost. It is also more convenient for medical staff to use and there is no need for separate training or complex clinical operations.

[0047] Embodiment 4:

[0048] Based on the above embodiments, considering the need for auxiliary support and fixation during endoscopic operation, such as Figure 7 As shown, a support member 320 is formed by protruding outward at the lower side of the outer surface of the holding ring 310. The support member 320 is in the shape of an upward curved surface with an auxiliary protrusion 330 on the curved surface. After the endoscope is inserted, the outwardly protruding support member 320 provides additional support for the endoscope. The auxiliary protrusion 330 is positioned close to the left and right sides of the endoscope to further assist in fixing.

[0049] The above only describes some exemplary embodiments of the present invention by way of illustration. For those skilled in the art, the described embodiments can be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are only illustrative and should not be construed as limiting the scope of protection of the claims of the present invention.
