Description

Technical Field

[0001] The utility model relates to the field of inflatable masks, in particular to an inflatable mask structure. Background Art

[0002] An inflatable mask is a mask used for conventional oxygen inhalation. Compared with nasal cannula oxygen inhalation, oxygen inhalation through a mask is more efficient, can provide moderate oxygen concentrations, and can be adjusted as needed to partially or completely avoid rebreathing. However, the mask is a fixed device and is not easy to expectorate or eat when used, so it is mainly used for emergency treatment or patients who require higher oxygen concentrations.

[0003] Existing oxygen masks are mostly used for nebulization therapy in respiratory medicine, etc. They are generally composed of components such as a cover, a lanyard and a joint. Before use, the doctor hangs the lanyard on the back of the user's head and connects the oxygen cylinder to the interface through a connecting device to complete the oxygen supply to the user. It has the advantages of simple operation and low production cost.

[0004] However, although the existing oxygen masks are designed to fit the human facial structure as much as possible in terms of the outer contour, they still do not fit the patient's face well. At the same time, the length of the hanging rope is fixed, so when encountering special groups (such as teenagers or infants), when such people use the oxygen mask, the elastic rope cannot firmly fix the mask shell on the end surface of their mouth and nose, causing outside air to enter the mask. Since the gas generated by atomization therapy is more humid than air, once the outside air enters the air, its humidity is greatly reduced, thereby reducing the effect of atomization therapy. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an inflatable mask structure to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an inflatable mask structure comprises a cover shell, a joint is installed at one end of the cover shell, and a fixed block is fixedly installed at one end of the cover shell, a sealing air cushion is fixedly installed at one end of the cover shell, and a one-way valve is fixedly installed at one end of the sealing air cushion, a hanging rope is fixedly installed at one end of the fixed block, a storage box is fixedly installed at one end of the cover shell, a storage roll is movably installed inside the storage box, and a control rod is fixedly installed at one end of the storage roll, the control rod is connected to the fixed block by the hanging rope, a first through hole for the movement of the hanging rope is opened inside the storage box, a limit assembly for limiting the control rod is arranged inside the storage box, the limit assembly comprises a pull plate, a connecting rod, a spring, a second through hole, a ratchet and a pawl, a connecting rod is movably installed inside the storage box, and a pull plate is fixedly installed at one end of the connecting rod, and a second through hole for the movement of the connecting rod is opened inside the storage box.

[0007] By adopting the above technical solution, by providing components such as a sealing air cushion, a storage box, a connecting rod, a spring and a ratchet, the length of the hanging rope can be manually controlled by turning the control rod during use, and the hanging rope can be tightened to fix the cover shell on the user's face. At the same time, the ratchet and the pawl cooperate to effectively ensure that the position of the cover shell will not be offset during use, effectively preventing external air or viruses from entering the patient's body with the patient's breathing, thereby effectively ensuring the effect of atomization treatment.

[0008] The utility model is further configured that a pawl is fixedly mounted on one end of the connecting rod, and a ratchet is fixedly mounted on one end of the control rod.

[0009] By adopting the above technical solution, a pawl is fixedly installed at one end of the connecting rod so that the position of the connecting rod can be controlled to control the pawl to move up and down inside the storage box. The pawl can control the ratchet to ensure that the ratchet can only move in one direction, thereby limiting the control rod and ensuring that the fixation of the cover shell is not affected during use.

[0010] The utility model is further configured that the outer sleeve of the pull plate is provided with a spring, and the storage box and the pawl are connected through the spring.

[0011] By adopting the above technical solution, the storage box is connected to the pawl through a spring, so that the spring will continuously apply elastic force to the pawl, so that the pawl and the ratchet are fitted together to ensure that it restricts the ratchet.

[0012] The utility model is further configured that a rotating groove for the control rod to move is opened inside the storage box, and the length of the pulling plate is greater than the length of the storage box.

[0013] By adopting the above technical solution, the rotating groove provides a rotating space for the control rod, and the length of the pull plate is greater than the storage box so that the user can better control the position of the pawl. Therefore, after use, the control of the control rod is released, and the fixed hanging rope becomes movable, which is convenient for removing the cover shell after use.

[0014] In summary, the utility model mainly has the following beneficial effects:

[0015] The utility model is provided with components such as a sealing air cushion, a storage box, a connecting rod, a spring and a ratchet, so that when the patient uses the utility model, gas is first injected into the sealing air cushion through a one-way valve to ensure that the cover shell will not excessively affect the user's face during use, thereby improving the comfort of the product. Subsequently, the length of the hanging rope can be manually controlled by rotating the control lever, and the hanging rope can be tightened to fix the cover shell on the user's face. At the same time, the ratchet and the pawl cooperate to effectively ensure that the position of the cover shell will not be offset during use, so that the cover shell and the human skin are firmly attached, effectively preventing external air or viruses from entering the patient's body with the patient's breathing, thereby effectively ensuring the effect of atomization treatment.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] An inflatable mask structure, such as Figure 1-4As shown, it includes a cover shell 1, a joint 3 is installed at one end of the cover shell 1, and a fixing block 5 is fixedly installed at one end of the cover shell 1, a sealing air cushion 2 is fixedly installed at one end of the cover shell 1, and a one-way valve 4 is fixedly installed at one end of the sealing air cushion 2, a hanging rope 6 is fixedly installed at one end of the fixing block 5, a storage box 7 is fixedly installed at one end of the cover shell 1, a storage reel 8 is movably installed inside the storage box 7, and a control rod 9 is fixedly installed at one end of the storage reel 8, the control rod 9 is connected to the fixing block 5 by the hanging rope 6, and a first through hole 14 for the hanging rope 6 to move is opened inside the storage box 7, The storage box 7 is provided with a limit assembly for limiting the control rod 9, and the limit assembly includes a pull plate 11, a connecting rod 12, a spring 13, a second through hole 15, a ratchet 16 and a pawl 17. The storage box 7 is provided with a connecting rod 12 movably installed inside, and a pull plate 11 is fixedly installed at one end of the connecting rod 12. The storage box 7 is provided with a second through hole 15 for the connecting rod 12 to move. The movably installed connecting rod 12 allows it to move inside the storage box 7 through the second through hole 15. The pull plate 11 is fixedly connected to the connecting rod 12, so that the user can move the connecting rod 12 through the pull plate. 11 can better control the position of the connecting rod 12. When using the utility model, the user picks up the cover shell 1 and puts it on the center of the patient's head. After the atomized medicine is connected to the cover shell 1 through the joint 3, the one-way valve 4 can ensure that the user quickly injects the gas into the sealed air cushion 2. The sealed air cushion 2 is relatively soft because it is filled with gas, which effectively protects the skin on the user's face. At the same time, because it has a certain plasticity, it can better fit the user's face. Then, the hanging rope 6 can be adjusted according to the size of the user's head. At the same time, the spring 13 continuously applies elastic force to the pawl 17, so that the pawl 17 restricts the ratchet 16, ensuring that the control rod 9 can only rotate in one direction, fixing and restricting the control rod 9, and at the same time ensuring that the position of the hanging rope 6 cannot move after the adjustment is completed, preventing the control rod 9 from being affected by the outside world and causing the position to change during use, thereby affecting its overall fixing effect. The movably installed connecting rod allows it to move inside the storage box through the second through hole, and the pull plate is fixedly connected to the connecting rod, so that the user can better control the position of the connecting rod through the pull plate.

[0024] See also Figure 4 A pawl 17 is fixedly installed at one end of the connecting rod 12, and a ratchet 16 is fixedly installed at one end of the control rod 9. The pawl 17 is fixedly installed at one end of the connecting rod 12 so that the position of the connecting rod 12 can be controlled to control the pawl 17 to move up and down inside the storage box 7. The pawl 17 can control the ratchet 16 to ensure that the ratchet 16 can only move in one direction, thereby limiting the control rod 9 and ensuring that the fixation of the cover shell 1 is not affected during use.

[0025] See also Figure 3 - Figure 4A spring 13 is provided on the outside of the pull plate 11, and the storage box 7 and the pawl 17 are connected by the spring 13. The storage box 7 and the pawl 17 are connected by the spring 13, so that the spring 13 will continuously apply elastic force to the pawl 17, so that the pawl 17 fits with the ratchet 16 to ensure that it restricts the ratchet 16.

[0026] See also Figure 1 - Figure 3 A rotating groove 10 is provided inside the storage box 7 for the control rod 9 to move. The length of the pull plate 11 is greater than the length of the storage box 7. The rotating groove 10 provides a rotating space for the control rod 9. The length of the pull plate 11 is greater than the storage box 7, so that the user can better control the position of the pawl 17. After use, the control of the control rod 9 is released, and the fixed hanging rope 6 becomes movable, which is convenient for removing the cover shell 1 after use.

[0027] The working principle of the utility model is as follows: when the user uses the utility model, after taking it out, the gas is injected into the sealed air cushion 2 through the one-way valve 4, the cover shell 1 is picked up and put on the center of the patient's head, and the atomized medicine is connected to the cover shell 1 through the joint 3. After completing the above preparations, the hanging rope 6 can be adjusted according to the size of the user's head. The user rotates the control rod 9 to drive the storage reel 8 to rotate, so that the hanging rope 6 enters the interior of the storage box 7 through the first through hole 14, and the length of the hanging rope 6 is manually controlled. At the same time, the spring 13 continuously applies elastic force to the ratchet 17 , so that the pawl 17 restricts the ratchet 16, ensuring that the control rod 9 can only rotate in one direction, fixing and restricting the control rod 9, and at the same time ensuring that the position of the hanging rope 6 cannot be moved after the adjustment is completed, preventing the control rod 9 from being affected by the outside world and causing the position to change during use, thereby affecting its overall fixing effect. After use, the user pulls the pull plate 11 to move the pawl 17 upward, releasing the restriction on the ratchet 16, and the hanging rope 6 is squeezed by its head to move. After rotating the control rod 9 to adjust its length, the cover shell 1 is taken out from the patient's head to complete the use of this product.
