Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an oral cavity filling mask for the elderly. Background Art

[0002] General anesthesia is referred to as general anesthesia. It refers to the temporary inhibition of the central nervous system caused by the inhalation of anesthetics into the body through the respiratory tract, intravenous or intramuscular injection. The clinical manifestations are loss of consciousness, loss of systemic pain, amnesia, reflex inhibition and skeletal muscle relaxation. This inhibition is completely reversible. When the drug is metabolized or excreted from the body, the patient's consciousness and various reflexes gradually recover. The implementation of general anesthesia can be mainly divided into several steps, including pre-anesthesia treatment, anesthesia induction, anesthesia maintenance and anesthesia recovery. Rapid induction is a commonly used anesthesia induction method in clinical practice. During induction, the patient first inhales pure oxygen 6L / min denitrification with a mask for 3 to 5 minutes, and then inhales high-concentration anesthetics or administers anesthetics intravenously. When the patient reaches the appropriate depth of anesthesia, endotracheal intubation can be performed to implement assisted or controlled breathing.

[0003] During the anesthesia induction process, mask pressurized oxygen delivery is a very important step, especially when the patient loses autonomous consciousness and spontaneous breathing and before endotracheal intubation. The anesthesiologist mainly maintains sufficient oxygen supply throughout the induction and intubation process by lifting the mandible, opening the airway, and using mask pressurized oxygen delivery. This is an important guarantee to ensure the patient's life safety throughout the induction process.

[0004] For thinner elderly patients, especially those with full or major tooth loss, the obvious defects on their cheeks make it difficult for the anesthesia mask to fit the patient's face well, making air leakage more likely to occur. In addition, during the airway opening process, the reverse jaw state is difficult to maintain due to tooth loss, and the tongue may fall back and block the airway. The above two reasons may lead to hypoxia and hypoxemia during intubation, posing a serious threat to the patient's life safety.

[0005] In view of the above problems, the present invention provides an oral cavity filling mask for the elderly. Summary of the invention

[0042] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. The present invention can also be implemented or applied through other different specific implementation methods. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0043] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0044] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0045] like Figure 1-12 An oral filling mask 11 for the elderly is shown, which comprises:

[0046] A wearing portion 1 that can be fixed on the patient's face;

[0047] The filling part 2 includes an airway 21, a filling airbag 22 and an inflation tube 23; the filling airbag 22 is wrapped outside the airway 21; one end of the inflation tube 23 is connected to the filling airbag 22; the filling airbag 22 includes at least two inflation bags; the inflation bags are connected; the filling airbag 22 is composed of a plurality of inflation bags, so that the filling airbag 22 can fill different amounts of gas into different inflation bags according to the internal shape of the patient's oral cavity, so that the filling airbag 22 can completely fill the patient's oral cavity;

[0048] The inflatable portion 3 is detachably connected to the side wall of the wearing portion 1; one end of the inflatable portion 3 passes through the wearing portion 1 and is detachably connected to the inflatable tube 23;

[0049] The treatment part 4 is detachably connected to the side wall of the wearing part 1 ; one end of the treatment part 4 passes through the wearing part 1 and is detachably connected to the ventilation channel 21 .

[0050] After the filling airbag 22 is placed in the patient's mouth, it is filled and supports the patient's mouth, filling the obvious defects of the patient's cheeks, so that the patient's face can fit the wearing part 1, blocking the gap between the wearing part 1 and the patient's face, effectively reducing the air leakage between the wearing part 1 and the patient's face, and no external force is required to press the wearing part 1, saving time and effort. The filling part 2 is fixed to the wearing part 1 through the treatment part 4, which limits the position of the filling part 2, prevents the filling part 2 from being displaced and causing a gap between the wearing part 1 and the patient's face, and can also avoid contusion of the patient's oral tissue due to the displacement of the filling part 2; in this process, the pulling force applied by the wearing part 1 to the filling part 2 through the treatment part 4 is opposite to the direction of the thrust applied by the wearing part 1 to the filling part 2 through the patient's face, so that the wearing part 1 and the filling part 2 are squeezed on both sides of the patient's facial skin at the same time, further preventing the formation of a gap between the wearing part 1 and the patient's face.

[0051] like Figure 2-12 As shown, the wearing part 1 includes a mask 11, a wearing airbag 12 and a limiting structure 13; the wearing airbag 12 is arranged at the edge of the mask 11; and the two ends of the limiting structure 13 are respectively connected to the two sides of the mask 11. When in use, the limiting structure 13 is used to fix the mask 11 on the patient's face. The wearing airbag 12 is the position where the wearing part 1 contacts the patient's facial skin. The wearing airbag 12 deforms after contacting the patient's face, increasing the contact area between the wearing part 1 and the patient's facial skin, reducing the pressure of the wearing part 1 on the patient's face, and preventing the patient's facial injury.

[0052] In some embodiments of the present application, an inflation port 121 is provided on the wearable airbag 12 , and air can be inflated into the wearable airbag 12 through the inflation port 121 .

[0053] Preferably, the inflation port 121 includes a tube body 1211, a piston 1212, a limiting ring 1213, an extrusion structure 1214 and a ventilation ring 1215; one end of the tube body 1211 is connected to the wearable airbag 12; the limiting ring 1213 and the ventilation ring 1215 are both fixed on the inner wall of the tube body 1211; one end of the extrusion structure 1214 presses the piston 1212 against the side wall of the limiting ring 1213, and the other end abuts against the ventilation ring 1215.

[0054] The piston 1212 is pressed to separate the piston 1212 from the stop ring 1213. The gas inside the wearable airbag 12 can be discharged through the inside of the vent ring 1215 and the gap between the piston 1212 and the stop ring 1213, and the wearable airbag 12 can be contracted. Similarly, when the piston 1212 is pressed, gas can be injected into the wearable airbag 12 through the gap between the piston 1212 and the stop ring 1213 and the inside of the vent ring 1215.

[0055] Specifically, the extrusion structure 1214 is a spring. After the piston 1212 is released, the spring wants to restore its original shape and presses the piston 1212 against the side wall of the limit ring 1213.

[0056] Preferably, the contact surface between the limiting ring 1213 and the piston 1212 is a guiding inclined surface, so that the piston 1212 can block the inside of the limiting ring 1213 and the wearing airbag 12 under the drive of the extrusion structure 1214.

[0057] The ventilation channel 21 includes a fixedly connected ventilation tube 211 and a positioning port 212. The positioning port 212 is detachably connected to the treatment part 4, and the filling air bag 22 is arranged on the outer wall of the ventilation tube 211. The ventilation tube 211 fixes the position of the patient's tongue while maintaining the gas flow in the patient's oral cavity, preventing the tongue from blocking the trachea during the operation, causing the patient to suffocate.

[0058] like Figure 1-12 As shown, the inflatable part 3 includes a first connecting component 31 and an air guide tube 32; the first connecting component 31 is detachably connected to the side wall of the wearing part 1. When in use, one end of the first connecting component 31 passes through the wearing part 1 and is detachably connected to the inflatable tube 23, and the other end is connected to the air guide tube 32; then the first connecting component 31 is fixed to the mask 11.

[0059] Preferably, a measuring structure 33 is provided. The measuring structure 33 is connected to the filling airbag 22 through the air guide tube 32 and the inflation tube 23, and the internal pressure of the filling airbag 22 can be sensed through the measurement result.

[0060] Specifically, the measuring structure 33 is an indicator balloon, and by squeezing the indicator balloon, the pressure of the filling airbag 22 can be sensed by touch.

[0061] Alternatively, the measuring structure 33 is a pressure gauge, and the pressure value of the filling airbag 22 can be obtained through the reading of the pressure gauge.

[0062] In some embodiments of the present application, the first connecting assembly 31 includes a first connecting tube and a limiting structure 313; one end of the first connecting tube is provided with a first enlarged end; the first enlarged end is in contact with the wearing portion 1; and the end of the first connecting tube away from the first enlarged end is detachably connected to the limiting structure 313. When in use, the first connecting tube is connected to the inflation tube 23 and then passed through the mask 11, and then the limiting structure 313 is fixed to the first connecting tube. At this time, the first enlarged end and the limiting structure 313 squeeze the mask 11 on both sides of the mask 11 at the same time, so as to achieve the effect of fixing the first connecting tube on the mask 11.

[0063] Preferably, the first connecting tube includes a first splicing structure 311 and a second splicing structure 312 ; the first splicing structure 311 and the second splicing structure 312 are wrapped around the outside of the inflation tube 23 after being spliced.

[0064] Furthermore, the first connecting tube also includes a first sealing structure; the first sealing structure is located between the first splicing structure 311 and the second splicing structure 312. The purpose of the first sealing structure is to increase the airtightness of the first connecting tube and prevent the first connecting tube from leaking. If the first connecting tube leaks, the filling airbag 22 will shrink, resulting in a gap between the wearing part 1 and the patient's face.

[0065] Specifically, the first connecting pipe is threadedly connected to the limiting structure 313. The limiting structure 313 is wrapped around the outside of the first connecting pipe to prevent the first splicing structure 311 from being separated from the second splicing structure 312, thereby causing the airtightness of the first connecting pipe to be lost.

[0066] In the schematic embodiment of the present application, a second through hole 114 is provided on the wearing portion 1; the first connecting tube passes through the wearing portion 1 through the second through hole 114. A second limiting tube 113 is also provided on the wearing portion 1; the axis of the second limiting tube 113 coincides with the axis of the second through hole 114. After the first connecting tube is installed on the mask 11, the second limiting tube 113 abuts against the first expanded end. The second limiting tube 113 wraps the end of the first connecting tube away from the limiting structure 313. The purpose of the second limiting tube 113 is to prevent the first splicing structure 311 and the second splicing structure 312 from being partially separated during use, so that a gap appears between the first splicing structure 311 and the second splicing structure 312, which causes the first connecting tube to leak air, causing the filling airbag 22 to shrink.

[0067] Specifically, the inner diameter of the second limiting tube 113 is greater than the outer diameter of the first expanded end.

[0068] In some examples of this application, such as Figure 1-12 As shown, the treatment part 4 includes a second connecting component 41 and a connecting tube 42; the second connecting component 41 is detachably connected to the side wall of the wearing part 1; one end of the second connecting component 41 passes through the wearing part 1 and is detachably connected to the ventilation channel 21, and the other end is detachably connected to the connecting tube 42.

[0069] The role of the treatment unit 4 is:

[0070] 1. The filling part 2 is fixed to the wearing part 1 through the treatment part 4 to limit the position of the filling part 2, to prevent the filling part 2 from being displaced during use and causing a gap between the mask 11 and the patient's face, and to avoid contusion of the patient's oral tissue due to the displacement of the filling airbag 22;

[0071] 2. One end of the treatment part 4 extending out of the mask 11 is connected to the anesthesia device, and inhalation anesthesia is provided to the patient through the treatment part 4 and the airway 21;

[0072] 3. The ventilator can be connected to the treatment unit 4 to effectively provide oxygen to the patient and ensure the patient's life safety.

[0073] Specifically, the second connecting assembly 41 is threadedly connected to the connecting pipe 42 .

[0074] In the specific example of the present application, the second connecting component 41 includes a second connecting tube 411, a positioning tube 413 and an elastic structure 414; one end of the second connecting tube 411 is detachably connected to the positioning tube 413, and the other end is detachably connected to the ventilation duct 21 after passing through the wearing portion 1; the second connecting tube 411 is provided with a second enlarged end at one end away from the positioning tube 413; the elastic structure 414 is wrapped around the outside of the second connecting tube 411; one end of the elastic structure 414 is abutted against the wearing portion 1, and the other end is connected to the second enlarged end.

[0075] The positioning tube 413 is wrapped around the outside of the second connecting tube 411; the positioning tube 413 is threadedly connected to the second connecting tube 411. By rotating the positioning tube 413, the second connecting tube 411 can be driven to gradually extend or gradually penetrate into the mask 11. By adjusting the length of the treatment part 4 extending into the cavity between the wearing part 1 and the patient's face, the distance between the wearing part 1 and the filling part 2 can be adjusted according to the patient's oral morphology to increase applicability. During use. The elastic structure 414 and the positioning tube 413 squeeze the mask 11 on both sides to prevent the first connecting tube from being displaced.

[0076] Specifically, the elastic structure 414 is a spring.

[0077] Preferably, the second connecting pipe 411 includes a third splicing structure 4111 and a fourth splicing structure 4112 ; the third splicing structure 4111 and the fourth splicing structure 4112 are wrapped around the outside of the ventilation channel 21 after being spliced.

[0078] Furthermore, the second connecting tube 411 further includes a second sealing structure; the second sealing structure is located between the third splicing structure 4111 and the fourth splicing structure 4112. The purpose of the second sealing structure is to increase the airtightness of the second connecting tube 411 to prevent air leakage in the second connecting tube 411. If the second connecting tube 411 leaks, the anesthetic or oxygen cannot be completely absorbed by the patient, resulting in insufficient anesthesia or suffocation of the patient.

[0079] Preferably, the second connection assembly 41 further includes a limiting tube 412; the limiting tube 412 is wrapped around the outside of the second expanded end; the limiting tube 412 is detachably connected to the second connection tube 411; the purpose of the limiting tube 412 is to prevent a gap from appearing between the third splicing structure 4111 and the fourth splicing structure 4112. One end of the elastic structure 414 abuts against the wearing portion 1, and the other end abuts against the limiting tube 412.

[0080] A limiting groove 4113 is disposed outside the second expanded end; a limiting block 4123 adapted to the limiting groove 4113 is disposed inside the limiting tube 412 to prevent the limiting tube 412 and the second connecting tube 411 from rotating.

[0081] Preferably, the limiting tube 412 includes a fifth splicing structure 4121 and a sixth splicing structure 4122; after the fifth splicing structure 4121 and the sixth splicing structure 4122 are spliced ​​together, they are wrapped around the outside of the second expanded end. There is a certain angle between the contact surfaces of the fifth splicing structure 4121 and the sixth splicing structure 4122 and the contact surfaces of the third splicing structure 4111 and the fourth splicing structure 4112, so as to ensure that the limiting tube 412 can be continuously wrapped around the outside of the second connecting tube 411.

[0082] like Figure 1-12 As shown, the wearing portion 1 is provided with a first through hole 112; the second connecting tube 411 passes through the wearing portion 1 through the first through hole 112; the wearing portion 1 is also provided with a first position limiting tube 111; the axis of the first position limiting tube 111 coincides with the axis of the first through hole 112. During use, the first position limiting tube 111 is wrapped around the outside of the elastic structure 414.

[0083] Specifically, the inner diameter of the first limiting tube 111 is greater than the outer diameter of the second expanded end.
