DETAILED DESCRIPTION

[0030] The present application is made based on the discovery and understanding of the inventor on the following facts and problems:

[0031] Before painless gastroscopy, the patient will be intravenously anesthetized, and the central nervous system will be temporarily inhibited after intravenous anesthesia. It is necessary to cover the oxygen inhalation mask 100 on the patient's face, increase the oxygen content of the patient's mouth and nose, and improve the patient's blood oxygen saturation to help the patient breathe, so as to avoid hypoxia caused by the failure of the respiratory system to work normally.

[0032] Since the medical staff needs to insert the optical fiber sensor through the patient's mouth during the gastroscopy process, and the oxygen mask 100 covers the patient's mouth, in the prior art, an opening is provided on the oxygen mask 100, the medical staff sends the optical fiber sensor to the vicinity of the patient's mouth through the opening, and then inserts the optical fiber sensor into the patient's body through the mouth. In this process, the optical fiber sensor will be in frictional contact with the oxygen mask 100, which will affect the feel of the medical staff during the process of inserting the optical fiber sensor. Moreover, due to the coverage of the oxygen mask 100, the process of the medical staff operating the patient's mouth will affect the seal between the oxygen mask 100 and the face, and the oxygen mask 100 cannot supply oxygen to the patient in time.

[0033] Therefore, the oxygen mask 100 according to the embodiments of the present application can have different states, cover the patient's nose to supply oxygen to the patient during the operation process of the medical staff, expose the patient's mouth outside the oxygen mask 100 to facilitate the operation of the medical staff, and cover the patient's mouth and nose at the same time when the medical staff does not need to operate, so as to better supply oxygen to the patient. Thus, not only can the patient obtain sufficient oxygen during the examination process to maintain the patient's blood oxygen saturation and ensure the patient's life safety, but also the oxygen mask 100 can avoid affecting the examination operation of the medical staff and facilitate the smooth use of the optical fiber sensor by the medical staff.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] The oxygen mask 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0038] like Figures 1-6 As shown, the oxygen mask 100 according to an embodiment of the present utility model includes: a mask body 10.

[0039] The mask body 10 covers the patient's face during the examination. The mask body 10 has a first state and a second state. In the first state, the mask body 10 covers the patient's mouth and nose. Since the oxygen mask 100 covers the patient's mouth and nose at the same time, it can increase the oxygen content near the patient's nose and mouth, provide sufficient oxygen to the patient, maintain the patient's blood oxygen saturation, and ensure the patient's life safety.

[0040] In the second state, the mask body 10 covers the nose. At this time, the oxygen mask 100 only covers the patient's nose, which can increase the oxygen content near the patient's nose, provide oxygen to the patient, maintain the patient's blood oxygen saturation, and ensure the patient's life safety. In addition, since the patient's mouth is no longer covered by the mask body 10, the oxygen mask 100 can avoid interfering with the medical staff's operation of inserting fiber optic sensors into the patient's mouth, making it easier for medical staff to use fiber optic sensors smoothly.

[0041] Specifically, the mask body 10 switches between two states by unfolding and folding. In order to ensure that the mask body 10 can change precisely between the first state and the second state during the folding process rather than deforming in other directions, the mask body 10 has a crease line 11, which divides the mask body 10 into a support part 12 and a deformable part 13.

[0042] The strength of the mask body 10 at the crease line 11 is different from the strength of the rest of the mask body 10. The strength at the crease line 11 is lower and it is more prone to deformation. During the folding process, medical staff can fold the deformable part 13 along the crease line 11 towards the side closer to the support part 12. The mask body 10 is bent at the crease line 11 so that the mask body 10 can switch between the first state and the second state.

[0043] In the first state, at least part of the mask body 10 is in sealing engagement with the chin part of the patient's face, and at least part of the mask body 10 in sealing engagement with the chin part of the patient's face can surround the mouth of the patient, and together with the remaining part of the structure surrounding the nose of the patient, define a space that can cover the mouth and nose of the patient at the same time, so that the mask body 10 can cover the nose and mouth of the patient at the same time, increase the oxygen content near the nose and mouth of the patient, and fully oxygenate the patient, maintain the blood oxygen saturation of the patient, and ensure the safety of the patient.

[0044] In the second state, at least part of the mask body 10 is in sealing engagement with the philtrum part of the patient's face. At this time, at least part of the mask body 10 in sealing engagement with the philtrum part of the patient's face can avoid the mouth of the patient, and together with the remaining part of the structure surrounding the nose of the patient, define a space that can only cover the nose of the patient, increase the oxygen content near the nose of the patient, oxygenate the patient, maintain the blood oxygen saturation of the patient, ensure the safety of the patient, and because the mouth of the patient is no longer covered by the mask body 10, the oxygen inhalation mask 100 can avoid affecting the medical staff to place the optical fiber sensor into the mouth of the patient, and facilitate the medical staff to use the optical fiber sensor smoothly.

[0045] According to the oxygen inhalation mask 100, the operation difficulty of the medical staff to place the optical fiber sensor into the mouth of the patient can be simplified without affecting the normal oxygen supply to the patient, and the medical staff can use the optical fiber sensor smoothly.

[0046] In combination with the embodiment shown in Figures 1-6 When the mask body 10 covers the patient's face, the support part 12 and the patient's face together define a first cavity 121 with a first opening 1211, and the crease line 11 defines the first opening 1211. The first cavity 121 can at least cover above the nose of the patient, and by sending oxygen into the first cavity 121, the oxygen content of the nose of the patient can be increased to ensure normal oxygen supply to the patient.

[0047] In the first state, the deformation part 13 and the patient's face together define a second cavity 131 with a second opening 1311, the first opening 1211 of the first cavity 121 and the second opening 1311 of the second cavity 131 are in communication, and the crease line 11 simultaneously defines the first opening 1211 and the second opening 1311. Therefore, the deformation part 13 closes the first opening 1211, the support part 12 closes the second opening 1311, and the cavity composed of the first cavity 121 and the second cavity 131 is closed, and the oxygen inhalation mask 100 can stably supply oxygen to the patient.

[0048] In the second state, the mask body 10 is folded at the crease line 11, the deformation portion 13 is folded and arranged in the first cavity 121, and cooperates with the patient's face to define an avoidance cavity 132 in communication with the first opening 1211. In the second state, the deformation portion 13 can close the first opening 1211, so that the first cavity 121 can be sealed, ensuring that the oxygen mask 100 can stably supply oxygen to the patient, increasing the oxygen content near the patient's nose, supplying oxygen to the patient, maintaining the patient's blood oxygen saturation, and ensuring the patient's life safety.

[0049] Since the deformation portion 13 is folded and arranged in the first cavity 121, the deformation portion 13 occupies part of the space in the first cavity 121 and defines the avoidance cavity 132 with an opening overlapping the first opening 1211. This part of the space can avoid the patient's mouth, so that the patient's mouth is located outside the range covered by the mask body 10, the patient's mouth is no longer covered by the mask body 10, and the oxygen mask 100 can avoid affecting the medical staff to perform the examination operation of inserting the optical fiber sensor into the patient's mouth, facilitating the medical staff to use the optical fiber sensor smoothly.

[0050] In addition to the bending at the crease line 11, the deformation portion 13 protrudes outward from the first cavity 121 at the crease line 11 in the first state, and is recessed inward from the first cavity 121 at the crease line 11 in the second state. The deformation portion 13 produces different bending states during switching between the first state and the second state.

[0051] In some embodiments, in the first state, the second cavity 131 covers above the patient's mouth, and the first cavity 121 covers above the patient's nose. Since the first opening 1211 is in communication with the second opening 1311, the oxygen sent into the first cavity 121 can enter the second cavity 131 through the first opening 1211 and the second opening 1311, oxygen is sent into the second cavity 131, the oxygen content in the second cavity 131 increases, and the oxygen content near the patient's mouth is improved.

[0052] In the second state, the first cavity 121 covers above the patient's nose, the deformation portion 13 is folded and arranged in the first cavity 121 and located below the patient's nose, and the cavity defined by the support portion 12 and the deformation portion 13 covers above the patient's nose. The oxygen mask 100 can stably supply oxygen to the patient by increasing the oxygen concentration near the patient's nose, maintain the patient's blood oxygen saturation, and ensure the patient's life safety.

[0053] In some embodiments, the first cavity 121 covers at least a portion of the patient's nose and mouth, and the second cavity 131 covers another portion of the patient's mouth. The oxygen supplied into the first cavity 121 can enter the second cavity 131 through the first opening 1211 and the second opening 1311 due to the communication between the first opening 1211 and the second opening 1311. The first cavity 121 and the second cavity 131 have a high oxygen concentration, which increases the oxygen content near the patient's nose and mouth, and provides sufficient oxygen supply to the patient, maintains the patient's blood oxygen saturation, and ensures the patient's life safety.

[0054] In the second state, the first cavity 121 covers the patient's nose and another portion of the mouth, and the deformation portion 13 is folded and arranged in the first cavity 121 below the patient's nose. The deformation portion 13 defines an avoidance cavity 132 to isolate the other portion of the mouth covered by the first cavity 121 from the cavity defined by the support portion 12 and the deformation portion 13. The cavity defined by the support portion 12 and the deformation portion 13 only covers the patient's nose. The oxygen mask 100 can stably supply oxygen to the patient by increasing the oxygen concentration near the patient's nose, maintain the patient's blood oxygen saturation, and ensure the patient's life safety.

[0055] In some embodiments, the mask body 10 is an integrally formed plastic piece, in which the thickness of the mask body 10 at the support portion 12 is much greater than the thickness of the mask body 10 at the deformation portion 13. The integrally formed plastic piece is beneficial to ensure the sealing performance of the mask body 10. In addition, the plastic material has different properties under different thickness conditions. The thickness of the support portion 12 is relatively thick, so that the support portion 12 has high strength and hardness, and the structure of the support portion 12 of the mask body 10 is not easily deformed by external force, ensuring that the mask body 10 can be stably supported above the face. The thickness of the deformation portion 13 is relatively thin to reduce the strength of the mask body 10 at the deformation portion 13. The deformation portion 13 of the mask body 10 can be deformed under the action of external force without being damaged. The thickness difference exists at the junction of the deformation portion 13 and the support portion 12, and the crease formed at this position is more easily folded and deformed.

[0056] In some embodiments, the first cavity 121 covers at least a portion of the patient's nose and mouth, and the second cavity 131 covers another portion of the patient's mouth. The oxygen supplied into the first cavity 121 can enter the second cavity 131 through the first opening 1211 and the second opening 1311 due to the communication between the first opening 1211 and the second opening 1311. The first cavity 121 and the second cavity 131 have a high oxygen concentration, which increases the oxygen content near the patient's nose and mouth, and provides sufficient oxygen supply to the patient, maintains the patient's blood oxygen saturation, and ensures the patient's life safety. Figure 5 and Figure 6As shown, the mask body 10 includes a cover shell 2 and a deformation piece 3, the material of the cover shell 2 has a strength far greater than the strength of the material of the deformation piece 3. The cover shell 2 and the deformation piece 3 can be made of different materials, wherein the material of the cover shell 2 part adopts a transparent material with high hardness and strength to achieve support for the mask body 10 and ensure that the mask body 10 can be stably supported above the face. The deformation part 13 can be made of a soft material with flexibility and elasticity, such as thin plastic or rubber, etc., to ensure that the deformation part 13 can be folded and deformed into the first cavity 121 or produce different bending. A certain flexibility ensures that the shape of the deformation part 13 can remain consistent before and after deformation in multiple deformations, and ensures that the state of the mask body 10 can be stably switched between the first state and the second state.

[0057] In some embodiments, the cover shell 2 and the deformation piece 3 are detachably connected. The service life of the deformation piece 3 is far less than the service life of the cover shell 2 due to long-term deformation. The detachable connection of the deformation piece 3 and the cover shell 2 can increase the service life of the cover shell 2 part in the mask body 10. After the deformation piece 3 is damaged, only the deformation piece 3 needs to be replaced, thereby reducing the use cost of the oxygen inhalation mask 100.

[0058] Referring to Figure 5 and Figure 6 , the deformation piece 3 includes a connecting part 31, and the cover shell 2 includes a matching part 21. The connecting part 31 and the matching part 21 cooperate to achieve sealed connection of the deformation piece 3 and the cover shell 2.

[0059] In some embodiments, the connecting part 31 and the matching part 21 are stacked in the thickness direction of the mask body 10 to increase the connection area of the deformation piece 3 and the cover shell 2 and ensure the stability of the connection of the cover shell 2 and the deformation piece 3. The connecting part 31 and the matching part 21 can be connected by adhesion. The adhesion mode is not limited to gluing, magic tape, etc. The adhesion connection can simplify the connection difficulty of the connecting part 31 and the matching part 21 and ensure the sealing of the connection part of the connecting part 31 and the matching part 21.

[0060] As shown in Figure 5 and Figure 6 , the deformation piece 3 needs to be deformed during the state change of the mask body 10. The deformation of the deformation piece 3 includes two parts, one part is the bending deformation at the position of the crease line 11, and the other part is the inward bending or outward bending deformation of the deformation part 13. The crease line 11 and the deformation part 13 are located in the deformation piece 3 to deform the material of the deformation piece 3 which is soft and has flexibility and elasticity. The crease line 11 coincides with the contour line of the cover shell 2. The strength of the cover shell 2 at the position or the overlapping part of the cover shell 2 and the deformation piece 3 is higher. The strength changes greatly at the junction of the cover shell 2 and the deformation piece 3. During the bending deformation of the deformation piece 3, the deformation piece 3 is more likely to fold at the junction of the deformation piece 3 and the cover shell 2, that is, at the contour line of the cover shell 2.

[0061] In some embodiments, the crease line 11 is located outside the outline of the mask shell 2 to avoid the bending of the deformation member 3 being affected by the mask shell 2.

[0062] In some embodiments, the deformation member 3 is treated differently on both sides of the crease line 11, for example, the side of the crease line 11 away from the deformation portion 13 is hardened, while the material of the deformation portion 13 remains soft and has flexibility and stretchability. Alternatively, the deformation member 3 is thinned at the crease portion, and when the deformation member 3 is deformed under external force, the thinned crease portion deforms first and bends towards the side close to the support portion 12.

[0063] Further, since the crease line 11 changes the most during the transformation between the first state and the second state, and the strength of the crease portion is lower than that of the rest of the mask body 10, the crease portion is prone to damage during multiple folding processes, resulting in a decrease in the sealing performance of the mask body 10.

[0064] Therefore, the oxygen inhalation mask 100 further comprises a sealing member, the sealing member comprises a sealing film, the sealing film is arranged on the inner surface and / or the outer surface of the mask body 10 and covers at least the crease line 11, and the sealing film can be a polyvinyl chloride film. The sealing film made of this material can maintain the sealing performance during multiple bending and deformation processes, has higher fatigue strength, and will not be damaged during multiple deformation and folding processes, and can ensure the sealing performance of the crease line 11 even if the sealing film is damaged at the crease line 11.

[0065] In some embodiments, the sealing member further comprises a sealing strip, the sealing strip is arranged at the connection between the mask shell 2 and the deformation member 3 to ensure the sealing performance of the connection between the mask shell 2 and the deformation member 3.

[0066] In combination Figures 3-6 In the illustrated embodiment, the oxygen inhalation mask 100 further comprises an inflatable air bag 5, the inflatable air bag 5 is arranged at the edge of the mask body 10 and is in contact with the patient's face. The inflatable air bag 5 can ensure that the connection between the mask body 10 and the patient's face is stably sealed. For different facial structures of different patients, the inflatable air bag 5 can adapt during the inflation process to ensure that it can fit different facial structures of different patients.

[0067] And, since the deformation part 13 cooperates with different facial structures at different positions of the patient in the first state and the second state, in the first state, the deformation part 13 edge part cooperates with the lower jaw part of the patient, in the second state, the deformation part 13 edge part cooperates with the philtrum part of the patient, the two different facial structures have great differences in height and shape, in order to ensure that the part structure can cooperate with the patient's face in the first state and the second state, the inflatable air bag 5 can compensate for the difference caused by the height difference or the shape between the patient's face and the edge part of the mask body 10, and the sealing of the inflatable air bag 5 ensures the sealing of the oxygen inhalation mask 100.

[0068] Wherein, the inflatable air bag 5 comprises an inflation port, and the inflation port is provided with an inflation valve, and the inflation valve only allows gas to be inflated into the inflatable air bag 5 from the outside.

[0069] Referring to Figures 3-6 , the support part 12 is provided with an oxygen hole 4, and the oxygen hole 4 is provided with an oxygen supply pipe joint. The oxygen supply machine sends oxygen into the cavity defined by the mask body 10 through the oxygen supply pipe joint arranged at the oxygen hole 4. The oxygen hole 4 is arranged on the support part 12, which can avoid the influence of the opening of the oxygen hole 4 on the switching of the mask body 10 between the first state and the second state.

[0070] Referring to Figures 1-6 , the oxygen inhalation mask 100 further comprises a fixing strip 6 arranged on both sides of the support part 12. The end of the fixing strip 6 arranged on one side of the support part 12 away from the mask body 10 is connected with the end of the fixing strip 6 arranged on the other side of the support part 12 away from the mask body 10. The fixing strip 6 has elasticity. During the intubation process of the patient, the patient always maintains a left lateral decubitus posture. It is difficult to fix the oxygen inhalation mask 100 on the patient's face. The arrangement of the fixing strip 6 can ensure the stability of the arrangement of the oxygen inhalation mask 100 on the patient's face, and ensure that the oxygen inhalation mask 100 stably supplies oxygen to the patient.
