Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an endoscopic oxygen supply anesthesia mask. Background Art

[0002] Endoscopic anesthesia masks are divided into single-hole endoscopic anesthesia masks and multi-hole endoscopic anesthesia masks. Endoscopic anesthesia masks can be used for endoscopic examinations and surgeries. Compared with the method of oxygen supply through a nasal cannula, it has greater advantages, is safer and more feasible, and provides better oxygen supply effects to patients.

[0003] During use, the jack on the endoscopic anesthesia mask can be opened, and then the endoscope can be inserted through the jack. However, the oxygen supply tube of the endoscopic anesthesia mask must be located near the lower end of the endoscopic anesthesia mask. When worn on the patient's head, the oxygen supply tube will be close to the lower part of the mouth and will be a certain distance away from the patient's nasal cavity. When the jack is opened, oxygen loss will occur, and the patient's oxygen saturation cannot be ensured to remain stable.

[0004] For example, in an endoscope mask disclosed in a Chinese patent application numbered CN201620836189.2, the telescopic tube for oxygen supply needs to be set near the lower end of the mask, and a plug is set in the middle. When the endoscope needs to be inserted, the plug hole in the middle needs to be opened, and opening the plug hole will cause the problem of oxygen loss. Moreover, when a small piece of the plug is removed along the two cutting lines, the plug hole will be larger, which will cause faster oxygen loss.

[0005] In order to avoid excessive oxygen loss, one solution may be to design the diameter of the hole to be smaller, but a hole with a smaller diameter will directly affect the operation of the endoscope, causing inconvenience in operation, and is therefore not desirable.

[0006] Therefore, the inventor has designed an endoscopic oxygen supply anesthesia mask which can better avoid oxygen loss without affecting endoscopic operation. Utility Model Content

[0035] Example:

[0036] like Figures 1 to 3 The figure shows an endoscopic oxygen supply anesthesia mask of the present embodiment, which includes an airbag cushion 1, a cup 2, a soft cover 3, a main oxygen tube 6 and an oxygen distribution tube 9.

[0037] The airbag cushion 1 is arranged in a circle on the inner side of the endoscopic oxygen supply anesthesia mask. A one-way valve 5 is arranged on the airbag cushion 1, and the one-way valve 5 is connected to the inside of the airbag cushion 1. The one-way valve 5 is used to inflate the inside of the airbag cushion 1. When in use, the airbag cushion 1 contacts the human face. The cup 2 is fixedly mounted on the airbag cushion 1 and is located in front of the airbag cushion 1. The soft cover 3 is arranged in the middle of the cup 2. The middle of the soft cover 3 is provided with a plug 3.2. When in use, the plug 3.2 can be removed to open the plug 3.1, and the endoscope can be inserted through the opened plug 3.1.

[0038] In this embodiment, a three-way joint 10 is fixedly provided at the lower end of the cup 2, and one interface of the three-way joint 10 passes through the outside of the cup 2 and is connected to the main oxygen pipe 6, so that the main oxygen pipe 3 is connected to the lower end of the cup 2. A sealing gasket 11 is sleeved on the interface 10.1 of the three-way joint 10 located outside the cup, and the sealing gasket 11 is cushioned at the connection between the three-way joint 10 and the cup 2 to form a seal. The other two interfaces of the three-way joint 10 are located inside the cup 2, and the two interfaces 10.2 located inside the cup are smaller than the interface 10.1 passing through to the outside of the cup, and the two interfaces located inside the cup are respectively provided with a conical head.

[0039] The oxygen distribution tube 9 is arranged inside the endoscopic oxygen supply anesthesia mask. The oxygen distribution tube 9 of this embodiment is a circular tube bent into a ring. The two ports 9.2 of the oxygen distribution tube 9 are located at its lower end and are respectively connected with the conical heads of the two interfaces of the three-way joint 10 located in the cup 2, thereby connecting the oxygen distribution tube 9 with the main oxygen tube 6.

[0040] An air outlet 9.1 is provided at the upper end of the oxygen distribution tube 9, and oxygen will be output from the air outlet 9.1. When the endoscopic oxygen supply anesthesia mask is worn on the human head, the air outlet 9.1 will be close to the human nasal cavity, thereby directly guiding the oxygen to a position close to the human nasal cavity through the oxygen distribution tube 9.

[0041] This embodiment further provides an adjustment structure, which is provided at the upper end of the oxygen distribution tube 9 and is used to adjust the upper end of the oxygen distribution tube 9, that is, the oxygen supply position of the oxygen distribution tube 9. By adjusting the upper end of the oxygen distribution tube 9 by the adjustment structure, the distance between the air outlet 9.1 and the human nasal cavity can be adjusted, so as to adapt to different patients and meet the needs of different scenes.

[0042] The specific structure of the adjustment structure is: including an adjustment plate 4, such as Figure 6 and Figure 7 As shown, an integrally formed adjusting piece 4.1 is provided in the middle of the adjusting plate 4, and long strip notches 4.4 are respectively provided on both sides of the adjusting piece 4.1, the outer end of the adjusting piece 4.1 is connected to the adjusting plate 4, and an arc-shaped claw 4.3 is provided at the inner end of the adjusting piece 4.1, and the inner diameter of the arc-shaped claw 4.3 is slightly larger than the outer diameter of the oxygen distribution pipe 9. The thickness of the adjusting piece 4.1 is less than the thickness of the adjusting plate 4, and one surface of the adjusting piece 4.1 is flush with the surface of the adjusting plate 4, and a plurality of clamping strips 4.2 are arranged side by side on the surface of the adjusting piece 4.1, and the arrangement direction of the clamping strips 4.2 is the length direction of the adjusting piece 4.1. A flat adjustment hole 2.1 is provided on the cup 2, and the adjustment plate 4 is inserted into the adjustment hole 2.1. The arc-shaped claw 4.3 at the inner end is buckled on the upper end of the oxygen distribution tube 9 and can rotate relative to the oxygen distribution tube 9. The adjustment plate 4 is clamped on the adjustment hole 2.1 through the clamping strip 4.2 thereon. By pushing the adjustment plate 4 inward or pulling it outward, the position of the upper end of the oxygen distribution tube 9 can be adjusted forward and backward.

[0043] The main oxygen pipe 6 of this embodiment is a bellows expansion pipe. The end of the main oxygen pipe 6 away from the cup 2 is provided with a standard connector 7 for connecting to an external breathing machine, anesthesia machine and other equipment.

[0044] The endoscopic oxygen supply anesthesia mask of this embodiment is also provided with a hanging rope 8, through which the mask can be worn on the human head.

[0045] The use process of the endoscopic oxygen supply anesthesia mask of this embodiment is as follows:

[0046] When in use, the endoscopic oxygen supply anesthesia mask is worn on the human head, and the position of the upper end of the oxygen distribution tube 9 can be adjusted forward and backward by adjusting the adjustment plate 4, so that the position of the air outlet 9.1 of the oxygen distribution tube 9 meets the requirements, and the oxygen input from the main oxygen tube 6 will enter the oxygen distribution tube 9, and directly output to a position close to the human nasal cavity through the air outlet 9.1 of the oxygen distribution tube 9. When it is necessary to use an endoscope, the jack 3.1 in the middle of the software cover 3 can be opened, and then the endoscope can be inserted. Since the oxygen is directly output at a position close to the human nasal cavity, and no longer far away from the nasal cavity, when the jack 3.1 on the software cover 3 is opened, the patient can also directly inhale the oxygen output near the nasal cavity, thereby reducing oxygen loss and ensuring that the patient's oxygen saturation remains stable.

[0047] It can be seen that the utility model effectively improves the oxygen supply of the endoscopic oxygen supply anesthesia mask and the convenience of doctor operation.
