Description

Technical Field

[0001] This utility model relates to the technical field of medical supplies, specifically to an anti-choking device. Background Technology

[0002] Asphyxiation is a leading cause of death in children, especially those under the age of four. It is also a major cause of brain damage in young children.

[0003] The standard procedure for addressing childhood suffocation is the Heimlich maneuver. However, the Heimlich maneuver usually requires assistance from another person, and the rescuer generally needs to be professionally trained. There are also age restrictions for the person being rescued. Improper execution can easily cause fractures, internal organ tears, and other serious injuries.

[0004] While existing anti-asphyxiation products on the market can help clear a completely blocked upper airway in certain situations, they also have some drawbacks. They require manual suction from another person using both hands, which is difficult for the asphyxiated person to perform themselves or for patients requiring additional assistance, such as infants. The suction power of the product depends on the force and speed with which the user manually pulls the product, making it unsafe, inconvenient, and inconsistent in effectiveness. Utility Model Content

[0005] The purpose of this invention is to provide an anti-choking device to solve the problems of unsafe and inconvenient operation of existing anti-choking products.

[0030] The technical solution of this utility model will be clearly and completely described below with reference to specific implementation schemes. However, those skilled in the art should understand that the implementation schemes described below are only for illustrating this utility model and should not be regarded as limiting the scope of this utility model. Based on the implementation schemes in this utility model, all other implementation schemes obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] like Figure 1 As shown in Figure 6, the anti-choking device 100 according to an embodiment of the present invention includes: a cylinder 101, a suction nozzle 102, a piston rod 10, a switch assembly 20, and an end cap assembly 30.

[0032] The cylinder 101 has an inner cavity 103 inside, an air inlet valve 104 is provided at the lower end of the inner cavity 103, and an air outlet valve 105 is provided at the upper end of the inner cavity 103.

[0033] The suction nozzle 102 is located at the lower end of the cylinder 101 and is connected to the air inlet valve 104. The piston push rod 10 is movably located inside the cylinder 101 and is elastically abutted against the upper end of the inner cavity 103 by the first spring 11. The piston push rod 10 can seal the air outlet valve 105. A valve cover (not shown) is provided on the outer periphery of the air outlet valve 105 to prevent the air outlet valve 105 from being squeezed.

[0034] The switch assembly 20 includes a button 21, a locking piece 22, a second spring 23, and a fixing frame 24. The fixing frame 24 is located at the upper end of the cylinder 101. The second spring 23 is installed on the inner side of the fixing frame 24. The second spring 23 is connected to one side of the locking piece 22. The button 21 is located at the upper end of the cylinder 101 and is connected to the other side of the locking piece 22. Under the elastic force of the second spring 23, the locking piece 22 is engaged with the piston push rod 10. Pressing the button 21 causes the locking piece 22 to squeeze the second spring 23, and the locking piece 22 moves away from the piston push rod 10.

[0035] The end cap assembly 30 is disposed at the upper end of the cylinder 101 and is connected to the end of the piston push rod 10. The end cap assembly 30 moves with the piston push rod 10.

[0036] The anti-choking device 100 of this utility model can cause the piston rod 10 to move upward away from the inner cavity 103 by pressing the button 21, so that negative pressure is generated inside the cylinder 101, and the air inlet valve 104 and the air outlet valve 105 act in sequence to perform negative pressure inhalation for the patient.

[0037] This invention relates to an anti-choking device 100, which is easy to operate and can be triggered with a single button. In emergencies, no assistance is needed; the person experiencing choking can operate the device themselves. The anti-choking device 100 generates a constant negative pressure, maintaining it within a fixed range and preventing pressure fluctuations due to individual operation. This avoids situations where insufficient pressure fails to remove the foreign object, or excessive pressure causes secondary injury.

[0038] In some embodiments, such as Figures 1-4 As shown, the switch assembly 20 also includes a mounting bracket 25, which is cylindrical. A first through hole 251 is provided at the center of the mounting bracket 25, and an arc-shaped groove 252 is provided on the side wall of the mounting bracket 25. The first through hole 251 communicates with the arc-shaped groove 252. The mounting bracket 25 is located at the upper end of the cylinder 101. The end of the piston push rod 10 passes through the first through hole 251, and a locking plate 12 is provided at the end of the piston push rod 10. The locking plate 22 is arc-shaped and is located within the arc-shaped groove 252. A fixing frame 24 is mounted on the mounting bracket 25.

[0039] It is understandable that the end of the piston rod 10 is a thin round rod structure, and at the middle position of the thin round rod structure, a part of the side wall of the rod moves inward, so that an arc-shaped platform, namely the locking platform 12, is formed on the rod.

[0040] In some embodiments, such as Figure 5 As shown, the upper side of the cylinder 101 has an opening (not shown), the button 21 is located in the opening, and the button 21 is mounted on the mounting bracket 25.

[0041] In some embodiments, such as Figures 1-5As shown, the switch assembly 20 also includes an anti-accidental touch knob 26, which is rotatably disposed on the outer periphery of the mounting bracket 25 and can be rotated between the button 21 and the mounting bracket 25. The anti-accidental touch knob 26 can block the travel of the button 21.

[0042] It is understandable that by setting an opening and installing the button 21 and the anti-accidental touch knob 26 inside the opening, it is beneficial to limit the rotation range of the anti-accidental touch knob 26 and improve the stability of the button 21 and the anti-accidental touch knob 26.

[0043] In some embodiments, such as Figure 1 As shown, a sealing ring 13 is provided on the outer periphery of the piston push rod 10. When the piston push rod 10 moves up and down, the sealing ring 13 abuts against or moves away from the port of the inner cavity 103. The sealing ring 13 is used to seal the inner cavity 103.

[0044] In some embodiments, such as Figure 1 As shown, a plurality of screws 106 are also provided inside the cylinder 101. The plurality of screws 106 are used to connect the outer wall of the inner cavity 103 to the bottom of the mounting bracket 25.

[0045] In some embodiments, such as Figure 1 As shown, the upper end of the inner cavity 103 is provided with a frustum portion 1031, and a plurality of second through holes 1032 are provided on the frustum portion 1031, and the screw 106 passes through the second through holes 1032.

[0046] In some embodiments, such as Figure 6 As shown, the suction nozzle 102 is provided with multiple threaded holes 1021, the lower end of the screw 106 is provided in the threaded hole 1021, and a nut 1022 is also provided in the threaded hole 1021.

[0047] In some embodiments, such as Figure 1 and Figure 5 As shown, the end cap assembly 30 includes a piston cap 31 and a soft rubber pad 32. The piston cap 31 is located at the end of the piston push rod 10 and is connected to the upper end of the cylinder 101. The soft rubber pad 32 is fixedly installed on the piston cap 31.

[0048] In some embodiments, such as Figure 1 and Figure 5 As shown, the end cap assembly 30 also includes a decorative cover 33, which is disposed between the piston cover 31 and the upper end of the cylinder 101.

[0049] Understandably, the decorative cover 33 serves as a cushion and a connector.
