[0002] In emergency medical situations, oxygen masks are crucial medical equipment for ensuring patient safety. Their primary function is to deliver oxygen, maintain vital signs, and buy precious time for subsequent medical treatment. Whether for patients with acute respiratory failure or those suffering severe trauma, oxygen masks play a vital role in critical moments and are an indispensable part of emergency medical care. However, existing emergency oxygen masks have some limitations. For example, when endoscopic examinations or treatments are required, traditional oxygen masks cannot simultaneously meet the needs of oxygen supply and endoscopic procedures. This not only causes significant inconvenience for medical personnel but also negatively impacts patient treatment. Therefore, developing a new type of emergency oxygen mask that can simultaneously meet the needs of oxygen supply and endoscopic procedures is of great significance for improving the efficiency and quality of emergency medical care. Utility Model Content

[0003] The purpose of this invention is to provide an emergency oxygen mask to solve the problem that existing emergency oxygen masks cannot be used for endoscopic operations while supplying oxygen.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An emergency oxygen mask includes a mask body, a sealing airbag, and a cover. The mask body is provided with an oxygen tube connector. An endoscope perforation is provided on the mask body at a position corresponding to the human mouth. A cylindrical cover is fixedly connected to the outside of the mask body and is coaxially arranged with the endoscope perforation. The diameter of the cylindrical cover is larger than the diameter of the endoscope perforation. The portion of the mask body located inside the cylindrical cover is an abutment part. The sealing airbag has an annular structure and is fixed inside the cylindrical cover. The cover is detachably and fixedly connected to the cylindrical cover and is used to close the cylindrical cover.

[0006] When the cap is fixed to the cylindrical cover, the bottom surface, outer peripheral surface and top surface of the sealing airbag will respectively abut against the outer side of the abutting part, the inner side of the cylindrical cover and the inner side of the cap, so as to seal the gap between the cylindrical cover and the cap.

[0007] When the cap is not fixed to the shroud, an endoscope that penetrates the endoscope perforation can be inserted into the sealing airbag. When the endoscope penetrates the sealing airbag, the outer and inner circumferential surfaces of the sealing airbag will respectively abut against the inner surface of the shroud and the outer surface of the endoscope to seal the gap between the shroud and the endoscope.

[0008] Furthermore, the inner side of the abutment portion is provided with a ring array of several flexible support sheets.

[0009] Furthermore, the outer peripheral surface of the sealing airbag is bonded and fixed to the inner surface of the cylindrical cover.

[0010] Furthermore, the oxygen pipe connector, the hood, and the mask body are integrally formed.

[0011] Furthermore, the mask body is provided with connecting buckles on both the left and right sides, which are used to connect to the straps for fixing to the patient's head.

[0012] Furthermore, the connecting buckle and the mask body are integrally formed.

[0013] Furthermore, the cover includes a cover cylinder and a cover plate, the cover plate being fixedly connected to one end of the cover cylinder, and the inner side of the cover cylinder being threadedly connected to the outer side of the cylinder cover.

[0014] Furthermore, the outer surface of the cover cylinder has several anti-slip grooves.

[0015] Furthermore, the cap is made of a transparent material.

[0016] Furthermore, the mask body is made of a transparent material.

[0017] The emergency oxygen mask of this invention has many significant beneficial effects:

[0018] Meeting diverse needs: It innovatively solves the problem that traditional oxygen masks cannot simultaneously meet the needs of oxygen supply and endoscopic operations. By incorporating endoscope perforations, a sealing airbag, and a unique cap design, it ensures a stable oxygen supply during endoscopic examinations or treatments, avoiding disruptions to patient care due to operational conflicts, and greatly expanding the application scenarios of oxygen masks.

[0019] Enhanced sealing performance: The tight fit between the sealing cuff and the contact part, the sleeve and the cap, as well as the good seal during endoscope insertion, effectively prevents oxygen leakage. When not performing endoscopic procedures, the flexible support sheet provides support for the sealing cuff, ensuring stable sealing performance; during endoscopic procedures, the bent flexible support sheet not only fixes the endoscope but also further ensures the sealing effect, allowing patients to receive a sufficient and efficient oxygen supply under any circumstances.

[0020] Enhanced ease of use: The threaded connection between the cap and the mask is simple and convenient, and the anti-slip groove design allows medical staff to quickly install and remove the cap, saving operation time. The one-piece molded structure reduces gaps between parts, lowering the risk of oxygen leakage while also making the mask structure more stable and easier for medical staff to operate. The transparent mask body and cap allow medical staff to easily observe the patient's facial expressions, skin color, oral condition, and the status of the endoscope and sealing cuff, enabling timely and accurate judgment and operational adjustments.

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] Reference Figures 1-4 As shown, the emergency oxygen mask of this utility model includes a mask body 1, a sealing airbag 2, and a cover 3.

[0030] In this embodiment, the mask body 1 is provided with an oxygen tube connector 11 for connecting to an external oxygen supply device to ensure that oxygen can be smoothly delivered into the mask. An endoscope perforation 12 is provided on the mask body 1 at a position corresponding to the patient's oral cavity, allowing the endoscope to be inserted through this perforation when the patient needs to undergo an endoscopic examination. A cylindrical cover 13, coaxially arranged with the endoscope perforation 12, is fixed to the outside of the mask body 1. The diameter of the cylindrical cover 13 is larger than the diameter of the endoscope perforation 12; this design provides installation space for the sealing airbag 2. The portion of the mask body 1 located inside the cylindrical cover 13 is the abutment portion 14, which plays an important role in the sealing process.

[0031] In this embodiment, the sealing airbag 2 has a ring-shaped structure and is fixed inside the shroud 13. When the cover 3 is fixed to the shroud 13, the bottom, outer peripheral, and top surfaces of the sealing airbag 2 will respectively abut against the outer surface of the contact portion 14, the inner surface of the shroud 13, and the inner surface of the cover 3, thereby effectively sealing the gap between the shroud 13 and the cover 3 and preventing oxygen leakage. When the cover 3 is not fixed to the shroud 13, an endoscope penetrating the endoscope perforation 12 can be inserted into the sealing airbag 2. At this time, the outer peripheral and inner peripheral surfaces of the sealing airbag 2 will respectively abut against the inner surface of the shroud 13 and the outer surface of the endoscope, achieving a good seal between the shroud 13 and the endoscope. This ensures that oxygen can be effectively delivered to the patient's body during endoscopic examinations.

[0032] In this embodiment, the cap 3 is detachably and fixedly connected to the shroud 13 for sealing the shroud 13. When endoscopic operations are not required, the cap 3 can seal the shroud 13, ensuring the overall airtightness of the mask. When endoscopic examination is required, the cap 3 can simply be removed.

[0033] Furthermore, a number of flexible support pieces 141 are arranged in a ring array on the inner side of the contact portion 14. These flexible support pieces 141 play a key role in different usage scenarios.

[0034] When no endoscopic examination is being performed, the cap 3 is tightly connected to the shroud 13, thus sealing the shroud 13. At this time, the sealing airbag 2 is subjected to pressure applied by the cap 3. The flexible support pieces 141 play a supporting role in this process, providing stable support for the sealing airbag 2, ensuring that the sealing airbag 2 can maintain a stable shape under pressure, thereby effectively ensuring the sealing performance between the shroud 13 and the cap 3 and preventing oxygen leakage.

[0035] When an endoscopy is required, the procedure changes accordingly. Medical staff first remove the cap 3 from the tube 13, then insert the endoscope through the endoscope perforation 12. During insertion, the endoscope comes into contact with the flexible support pieces 141 and is pushed into a bent state. These bent flexible support pieces 141 are tightly pressed against the outside of the endoscope. In this way, the flexible support pieces 141 provide support and fixation for the endoscope, maintaining a relatively stable position during the examination. This facilitates precise operation by medical staff and improves the accuracy and safety of the endoscopy.

[0036] In this embodiment, the outer peripheral surface of the sealing airbag 2 is bonded and fixed to the inner side of the cover 13. This fixing method can ensure that the sealing airbag 2 will not be displaced during use, thus ensuring the stability of the seal.

[0037] In this embodiment, the oxygen pipe connector 11, the cylinder shroud 13, and the mask body 1 are integrally formed, which can enhance the structural strength of the entire mask, reduce the connection gaps between components, reduce the risk of oxygen leakage, and also facilitate production and manufacturing.

[0038] In this embodiment, connecting buckles 15 are provided on both the left and right sides of the mask body 1. The connecting buckles 15 are used to connect to the straps for fixing to the patient's head. The mask is fixed to the patient's head by the straps to ensure the stability of the mask during use. The connecting buckles 15 and the mask body 1 are integrally formed, which is also to enhance the structural strength and stability.

[0039] In this embodiment, the cover 3 includes a cover cylinder 31 and a cover plate 32. The cover plate 32 is fixedly connected to one end of the cover cylinder 31, and the inner side of the cover cylinder 31 is threadedly connected to the outer side of the cover 13. This threaded connection method is simple and convenient to operate, and medical staff can quickly install or remove the cover 3. The outer side of the cover cylinder 31 has several anti-slip grooves 311. When operating the cover 3, the anti-slip grooves 311 can increase the friction, making it easier for medical staff to twist the cover 3.

[0040] In this embodiment, both the cover 3 and the mask body 1 are made of transparent material. The transparent mask body 1 allows medical staff to observe the patient's facial expressions, skin color, and other conditions at any time, and to promptly assess changes in the patient's condition; the transparent cover 3 facilitates observation of the status of the sealing airbag 2 and the insertion of the endoscope.

[0041] When assembling the emergency oxygen mask of this utility model, firstly, the sealing airbag 2 is fixed to the inside of the cylindrical cover 13. After fixing the sealing airbag 2, the inner side of the cover tube 31 of the cap 3 is then threaded to the outer side of the cylindrical cover 13 until the cap 3 is in place. At this time, the bottom, outer peripheral, and top surfaces of the sealing airbag 2 will be tightly abutted against the outer side of the contact part 14, the inner side of the cylindrical cover 13, and the inner side of the cap 3, respectively, thus completing the sealed assembly of the mask. Finally, the straps are connected to the connecting buckles 15 on the left and right sides of the mask body 1, and the length of the straps is adjusted according to the actual size of the patient's head to ensure that the mask can be stably worn on the patient's head.

[0042] There are two scenarios for using the face mask. If the patient does not require endoscopic procedures, the oxygen tubing connector 11 of the oxygen supply device can be directly connected to an external oxygen source. The face mask is then placed on the patient's head and secured with straps. In this case, the cap 3 is in a closed-off state, creating a sealed environment. Oxygen enters the face mask through the oxygen tubing connector 11, providing necessary oxygen support to the patient. When the patient requires endoscopic procedures, medical staff first unscrew the cap 3 to remove it from the face mask 13. Then, the endoscope is inserted into the sealing cuff 2 through the endoscope perforation 12. The sealing cuff 2 and endoscope perforation 12 are observed, ensuring a tight seal between the outer and inner surfaces of the sealing cuff 2 and the inner surface of the face mask 13 and the outer surface of the endoscope, respectively. Afterward, the oxygen tubing connector 11 is connected to the oxygen source to supply oxygen to the patient. During this process, medical staff can observe the patient's oral cavity and the status of the endoscope and sealing cuff 2 through the transparent face mask body 1 and cap 3.

[0043] In summary, this novel emergency oxygen mask, through its innovative structural design, effectively addresses the shortcomings of traditional oxygen masks in meeting the needs of oxygen supply and endoscopic procedures. Its unique combination of the mask body 1, sealing airbag 2, and cap 3, along with the ingenious design of each component, such as the oxygen tubing connector 11, endoscope perforation 12, cylindrical cover 13, contact part 14 and its inner flexible support piece 141, and connecting buckle 15, ensures stable operation in various usage scenarios. During assembly, the connection method of each component guarantees both structural stability and ease of operation. In use, whether in routine oxygen supply scenarios without endoscopic procedures or in special situations requiring endoscopic examinations, it provides patients with a stable and efficient oxygen supply while meeting the requirements of endoscopic operations, offering convenience to medical personnel and effectively improving operational efficiency. This novel emergency oxygen mask is expected to be widely used in the field of emergency medical care, significantly improving the efficiency and quality of emergency medical care and providing stronger protection for patients' lives.
