Description

Technical Field

[0001] The present disclosure relates to the technical field of respiratory masks, and in particular to a valve head structure for a full-face mask. Background Art

[0002] Many patients need the help of a ventilator during diagnosis and treatment to relieve symptoms of sleep apnea and dyspnea. The ventilator and the patient are connected by a breathing tube and a mask, so that the air pressure generated by the ventilator is transmitted to the patient, opening the patient's airway and assisting breathing. While using a ventilator, patients often need to temporarily disconnect from the ventilator to carry out other activities, such as going to the toilet at night. In order to facilitate patients to quickly disconnect from the ventilator, they can also quickly connect to the ventilator without affecting the wearing of the mask, and improve the airtightness and comfort of the mask during use. This can be achieved by setting a quick disassembly and assembly structure between the breathing mask and the ventilator tube.

[0003] In related technologies, a rotating member is typically used to connect the ventilator's airway and the respiratory mask, achieved through an interference fit. The rotating member is then connected to the valve head on the respiratory mask using a snap-on design. To disconnect the ventilator, the rotating member must be pulled out, requiring considerable force and compromising the mask wearer's comfort. While the ventilator is in use, a considerable amount of force is required to connect the airway and mask, which can easily cause the mask to become misaligned or loose, potentially leading to air leakage during ventilation.

[0004] Therefore, the existing connection method between the ventilator trachea and the breathing mask requires applying a push or pull force to the patient's face when the ventilator needs to be disconnected or connected, which affects the airtightness and comfort of the mask. Utility Model Content

[0005] The purpose of the present disclosure is to overcome at least one of the above-mentioned shortcomings of the related art and provide a valve head structure for a full-face mask.

[0006] Additional aspects and advantages of the disclosure will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the disclosure.

[0007] According to one aspect of the present disclosure, a valve head structure for a full-face mask is provided. The full-face mask includes a mask body and a mask frame connected to the mask body, wherein the mask frame is provided with a connection hole. The valve head structure includes:

[0008] a valve head, the valve head comprising an upper end and a lower end, the lower end being inserted into the connecting hole and detachably connected to the mask frame;

[0009] a plug, the plug being detachably connected to the valve head via the upper end portion;

[0010] A quick-release member is sleeved on an end of the plug away from the valve head, and two quick-release structures are symmetrically provided on the quick-release member. The two quick-release structures are used to connect the quick-release member and the plug. Applying a force parallel to the patient's face to the quick-release structure can drive the quick-release structure to disconnect from the plug.

[0011] Wherein, the quick release part is rotatably connected to the plug, and the ventilator trachea is interference-connected to the quick release part.

[0012] In an exemplary embodiment of the present disclosure, a flange is provided at one end of the plug close to the upper end portion, and the quick-release structure includes:

[0013] A fixing buckle, provided on the outer side wall of the quick release component;

[0014] Wherein, one end of the fixing buckle close to the plug is bent toward the inside of the quick release component to form a stepped clamping platform, and the fixing buckle is clamped on the flange of the plug through the clamping platform.

[0015] In an exemplary embodiment of the present disclosure, the fixing buckle is an integrally formed structure and has a curvature, and the quick-release structure further includes:

[0016] A connecting portion is fixed to the middle portion of the fixing buckle, and an end of the connecting portion facing away from the fixing buckle is fixedly connected to the side wall of the quick-release member;

[0017] Among them, the part of the fixing buckle located on one side of the connecting part is a snap-on section, which is used to connect with the plug, and the part of the fixing buckle located on the other side of the connecting part is an extension section. When the extension section of the fixing buckle is pressed in the direction close to the quick-release part, the snap-on section of the fixing buckle rotates in the direction away from the plug.

[0018] In an exemplary embodiment of the present disclosure, the fixing buckle and the connecting portion are capable of elastic deformation.

[0019] In an exemplary embodiment of the present disclosure, an end portion of the fixing buckle close to the plug is arc-shaped.

[0020] In an exemplary embodiment of the present disclosure, one end of the quick release member close to the plug is inserted into the plug, a limiting ring is provided on the outer side wall of the quick release member, and the end face of the plug abuts against the limiting ring.

[0021] In an exemplary embodiment of the present disclosure, a receiving groove is provided on the upper end of the valve head, and the valve head structure further comprises:

[0022] The valve plate is arranged between the valve head and the plug and is clamped in the accommodating groove.

[0023] In an exemplary embodiment of the present disclosure, a limiting portion is provided in the accommodating groove, and a limiting recess adapted to the limiting portion is provided on the valve plate.

[0024] In an exemplary embodiment of the present disclosure, the valve head and the plug are connected via ultrasonic wave.

[0025] In an exemplary embodiment of the present disclosure, a connection groove is provided on an end surface of the plug close to the upper end portion, and an ultrasonic connection portion is provided on an end surface of the upper end portion close to the plug.

[0026] The valve head structure for a full-face mask disclosed herein has the following beneficial effects:

[0027] The valve head structure for the full-face mask disclosed herein is provided with a plug and a quick-release part between the ventilator trachea and the valve head. The quick-release structure provided on the quick-release part can connect the quick-release part to the plug. When it is necessary to detach the ventilator trachea from the full-face mask, a force parallel to the patient's face is applied to the quick-release structure to drive the quick-release structure to detach from the plug. In addition, there are two symmetrical quick-release structures. When the quick-release structure is detached from the plug, the forces applied to the two quick-release structures are relative. Therefore, when the ventilator trachea is detached from the full-face mask, the mask body is not easily misplaced or loosened, and will not affect the comfort and airtightness of the mask wearer.

[0028] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The terms "a", "an", "the", and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.; the terms "first" and "second" are used only as labels and do not limit the quantity of their objects.

[0042] A quick disassembly and assembly structure is set between the breathing mask and the ventilator trachea, which can facilitate the patient to quickly disconnect from the ventilator or quickly connect to the ventilator without affecting the wearing of the mask, thereby improving the airtightness and comfort of the mask during use.

[0043] like Figure 1 As shown, in the related art, a valve head 11 is connected to the respiratory mask 1, a rotating part 12 is sleeved on the valve head 11, and the respiratory trachea is sleeved on the rotating part 12 and connected by interference fit. The rotating part 12 and the valve head 11 are connected in the form of a snap. When the ventilator is to be disconnected, the rotating part 12 needs to be pulled off from the valve head 11; and when the ventilator is used, a certain amount of force needs to be used to clamp the rotating part 12 on the valve head 11. Therefore, when disconnecting from or connecting to the ventilator, it is necessary to apply a push or pull force to the patient's face, which can easily cause the mask body to be dislocated or loose, and there is a possibility of air leakage, and it will also affect the comfort of the mask wearer.

[0044] Based on this, the embodiment of the present disclosure provides a valve head structure for a full-face mask. The full-face mask includes a mask body 2 and a mask frame 3 connected to the mask body 2. The mask frame 3 is provided with a connection hole 31. The valve head structure includes a valve head 4, a plug 5 and a quick-release part 6. The valve head 4 includes an upper end 42 and a lower end 41. The lower end 41 is inserted into the connection hole 31 and is detachably connected to the mask frame 3. The plug 5 is detachably connected to the valve head 4 through the upper end 42. The quick-release part 6 is sleeved on the end of the plug 5 away from the valve head 4. Two quick-release structures 7 are symmetrically provided on the quick-release part 6. The two quick-release structures 7 are used to connect the quick-release part 6 and the plug 5. Applying a force parallel to the patient's face to the quick-release structure 7 can drive the quick-release structure 7 to disconnect from the plug 5. The quick-release part 6 is rotatably connected to the plug 5, and the ventilator trachea is interference-connected to the quick-release part 6.

[0045] The valve head structure for the full-face mask disclosed herein is provided with a plug 5 and a quick-release part 6 between the ventilator trachea and the valve head 4. The quick-release structure 7 provided on the quick-release part 6 can connect the quick-release part 6 to the plug 5. When it is necessary to detach the ventilator trachea from the full-face mask, a force parallel to the patient's face is applied to the quick-release structure 7, which can drive the quick-release structure 7 to be disconnected from the plug 5. In addition, there are two quick-release structures 7 symmetrically provided. When the quick-release structure 7 is disconnected from the plug 5, the forces applied to the two quick-release structures 7 are relative. Therefore, when the ventilator trachea is detached from the full-face mask, the mask body 2 is not easily misplaced or loosened, and will not affect the comfort and airtightness of the mask wearer.

[0046] The following is a detailed description of the various parts of the valve head structure for a full-face mask provided by an embodiment of the present disclosure with reference to the accompanying drawings:

[0047] In the disclosed embodiment, the full-face mask includes a mask body 2 and a mask frame 3 fixedly connected to the mask body 2. The mask frame 3 is provided with a connection hole 31 for connecting to a valve head 4. The mask body 2 is snapped onto the patient's face, and the mask frame 3 is provided with a fixing buckle for fixing the full-face mask to the patient's face. The valve head 4 is used to control the inhalation or exhalation of gas.

[0048] In the disclosed embodiment, the valve head structure for a full-face mask includes a valve head 4, a plug 5, and a quick-release member 6. The valve head 4 includes an upper end 42 and a lower end 41. The lower end 41 is inserted into the connection hole 31 and is detachably connected to the mask frame 3. The upper end 42 of the valve head 4 is connected to the lower end 41. A fixed block is provided at the edge of the lower end 41. After being inserted into the connection hole 31, the lower end 41 is detachably connected to the mask frame 3 via the fixed block.

[0049] The plug 5 is detachably connected to the valve head 4 via its upper end 42. A connection groove 52 is defined on the end surface of the plug 5 near the upper end 42. An ultrasonic connector 43 is also defined on the end surface of the upper end 42 near the plug 5. The ultrasonic connector 43, located on the end surface of the plug 5, is inserted into the opening of the connection groove 52, thereby ultrasonically connecting the valve head 4 and the plug 5. Both the lower end 41 and the upper end 42 of the valve head 4 can be cylindrical for ease of connection. The plug 5 is cylindrical in shape.

[0050] The quick-release part 6 is sleeved on the end of the plug 5 away from the valve head 4. Two quick-release structures 7 are symmetrically arranged on the quick-release part 6. The two quick-release structures 7 are used to connect the quick-release part 6 and the plug 5. Applying a force parallel to the patient's face to the quick-release structure 7 can drive the quick-release structure 7 to disconnect from the plug 5. The quick-release part 6 is rotatably connected to the plug 5, and the ventilator trachea is interference-connected with the quick-release part 6. The quick-release part 6 is cylindrical in shape and sleeved on the plug 5 and can rotate. The quick-release part 6 and the plug 5 are connected by the quick-release structure 7. When the ventilator trachea needs to be removed, the quick-release structure 7 is opened to disconnect the quick-release part 6 from the plug 5, so that the ventilator trachea can be removed.

[0051] In addition, two quick-release structures 7 are symmetrically provided. When the ventilator trachea needs to be detached from the full-face mask, a force parallel to the patient's face is applied to the quick-release structures 7. The forces applied to the two quick-release structures 7 are opposite, which can drive the quick-release structures 7 to disconnect from the plug 5. In addition, the mask body 2 is not easily misaligned or loosened, and will not affect the comfort and airtightness of the mask wearer.

[0052] In the disclosed embodiment, the end of the plug 5 near the upper end 42 is provided with a flange 51, and the quick-release structure 7 includes a fixing buckle 71. The fixing buckle 71 is provided on the outer wall of the quick-release member 6. The end of the fixing buckle 71 near the plug 5 is bent toward the inside of the quick-release member 6 to form a stepped clamping platform 711. The fixing buckle 71 is clamped to the flange 51 of the plug 5 via the clamping platform 711.

[0053] Meanwhile, the fixing buckle 71 is an integrally formed structure with a curvature, and the quick-release structure 7 further includes a connecting portion 72. The connecting portion 72 is fixed to the middle portion of the fixing buckle 71, and the end of the connecting portion 72 facing away from the fixing buckle 71 is fixedly connected to the side wall of the quick-release member 6. The portion of the fixing buckle 71 located on one side of the connecting portion 72 is a snap-on section 712, which is used to connect to the plug 5, and the portion of the fixing buckle 71 located on the other side of the connecting portion 72 is an extension section 713. When the extension section 713 of the fixing buckle 71 is pressed toward the quick-release member 6, the snap-on section 712 of the fixing buckle 71 rotates away from the plug 5.

[0054] Furthermore, both the fixing buckle 71 and the connecting portion 72 can be elastically deformed.

[0055] It can be understood that the fixing buckle 71 and the connecting part 72 can form a clamp structure under the action of elasticity. The clamping section 712 of the fixing buckle 71 is a clamping arm, and the extension section 713 of the fixing buckle 71 is a force arm. When the extension section 713 is pressed, the clamping section 712 can rotate around the connecting part 72, so that the clamping platform 711 of the fixing buckle 71 can be clamped on the flange 51 of the plug 5. When it is necessary to detach the ventilator trachea, the extension sections 713 of the fixing buckles 71 on both sides of the quick-release part 6 are pressed simultaneously, so that the clamping sections 712 of the two fixing buckles 71 move away from each other, thereby disconnecting the quick-release part 6 from the plug 5; and when it is necessary to connect the quick-release part 6 to the plug 5, the extension sections 713 of the fixing buckles 71 on both sides of the quick-release part 6 can be pressed simultaneously, so that the clamping sections 712 of the two fixing buckles 71 move away from each other, and then the quick-release part 6 is put on the plug 5, and then the extension sections 713 of the fixing buckles 71 on both sides are released, the clamping sections 712 of the two fixing buckles 71 can automatically rebound, and the clamping platforms 711 of the two fixing buckles 71 are simultaneously clamped on the flange 51 of the plug 5, thereby connecting the quick-release part 6 to the plug 5.

[0056] In one embodiment of the present disclosure, the end of the fixing buckle 71 on the side close to the plug 5 is arc-shaped. The quick release member 6 is inserted into the plug 5 and moved toward the plug 5. During the movement, the arc-shaped end of the fixing buckle 71 abuts against the flange 51 of the plug 5. As the quick release member 6 moves, the fixing buckles 71 on both sides gradually move away from each other. When the quick release member 6 and the plug 5 are fully engaged, the bases 711 of the two fixing buckles 71 move out of the flange 51 and are elastically fixed to the flange 51.

[0057] In one embodiment of the present disclosure, one end of the quick release part 6 close to the plug 5 is inserted into the plug 5, and a limiting ring 61 is provided on the outer wall of the quick release part 6, and the end face of the plug 5 abuts against the limiting ring 61. When the quick release part 6 is needed to be connected to the plug 5, the quick release part 6 can be first inserted into the plug 5, and the quick release part 6 can be moved in a direction close to the plug 5. During the movement, the fixed buckles 71 on both sides will move away from each other. When the end of the plug 5 abuts against the limiting ring 61, the quick release part 6 is fully matched with the plug 5, and the bases 711 of the two fixed buckles 71 can be clamped on the flange 51 under the action of elasticity, thereby connecting the quick release part 6 to the plug 5.

[0058] In the disclosed embodiment, a receiving groove is defined at the upper end of the valve head 4, and the valve head structure also includes a valve disc 44. Valve disc 44 is positioned between the valve head 4 and the plug 5 and is secured within the receiving groove. A position-limiting portion is provided within the receiving groove, and a position-limiting recess is provided on the valve disc 44 that mates with the position-limiting portion. By inserting the valve disc 44 into the receiving groove and positioning the position-limiting portion within the position-limiting recess, the position of the valve disc 44 is secured.

[0059] Other embodiments of the present disclosure will readily occur to those skilled in the art after considering the specification and practicing the invention disclosed herein. This utility model is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only, with the true scope and spirit of the present disclosure being indicated by the appended claims.
