[0040] In the description of the present application, it needs to be understood that the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0041] In addition, the technical features involved in the different embodiments of the utility model described above can be combined with each other as long as there is no conflict between them.

[0042] The utility model provides a kind of variable cavity breathing balloon as Figures 1 to 4 The variable cavity breathing balloon is aimed at solving the shape uncontrollable shortcoming of existing breathing balloon after compression.

[0043] The variable cavity breathing balloon mainly includes: a folded balloon 100, a plurality of crease portions 120 disposed on the folded balloon 100, and two extrusion plates 200.

[0044] The folded balloon 100 has an air cavity 110 inside, and the volume of the air cavity 110 changes when the folded balloon 100 is compressed or expanded along its axial direction. In actual use, both hands can be placed at both ends of the folded balloon 100 in the axial direction, and the folded balloon 100 can be forced to flatten in opposite directions, at which time the volume of the air cavity 110 is reduced, generating positive pressure.

[0045] The folding balloon 100 is concave along its radial direction to form a crease part 120, and a plurality of crease parts 120 are arranged at intervals along the axis of the folding balloon 100. Specifically, the crease part 120 surrounds the folding balloon 100 along the axial direction for one turn, and when the folding balloon 100 is compressed along the axial direction, the side surface of the folding balloon 100 can be deformed along the crease part 120 due to the effect of the crease part 120, the interval between a plurality of crease parts 120 is reduced, so that the side surface of the folding balloon 100 is repeatedly folded, the compressed shape is controllable, and the arrangement is convenient.

[0046] Two extrusion plates 200 are arranged at two ends of the axial direction of the folding balloon 100, and the two extrusion plates 200 are perpendicular to the axial direction of the folding balloon 100, and the folding balloon 100 is used to be connected with the face mask 400, the oxygen connecting pipe 510 and the oxygen storage bag 520 through the two extrusion plates 200 respectively. Preferably, the outer diameter of the two extrusion plates 200 is larger than the outer diameter of the folding balloon 100, and the hardness is higher, so that the medical staff can easily exert force.

[0047] It can be understood that the breathing balloon is a temporary replacement device of the breathing machine, and the breathing machine is difficult to move, so the breathing balloon is generally carried by medical staff for use outside, and the storage space of the medical staff is precious, so the breathing balloon is generally carried after being emptied of internal gas. The existing breathing balloon, such as the patent with publication number CN219539152U, discloses a breathing balloon with reduced air leakage, which is integrally formed by a spherical balloon and a cylindrical balloon. Since the breathing balloon does not have a reserved crease, random creases are generated after compression, resulting in an uncontrollable compressed shape, which brings some trouble to the personnel arranging medical devices, and the creases are difficult to recover after long-term storage, which damages the elasticity of the breathing balloon.

[0048] In use, the two extrusion plates 200 are compressed towards each other, the length of the folding balloon 100 in the axial direction is reduced, and the plurality of crease parts 120 of the folding balloon 100 are close to each other during compression, the compressed shape is controllable, the arrangement is convenient, and the creases are not generated outside the crease part 120, so the breathing balloon has small elasticity loss after long-term storage.

[0049] In some embodiments, as shown in Figure 4 The variable-cavity breathing balloon further comprises a connecting buckle arranged on the opposite surfaces of the two extrusion plates 200, and the connecting buckle is used to connect the two extrusion plates 200 when the interval between the two extrusion plates 200 is less than a preset interval.

[0050] In actual use, the preset interval can be reasonably set according to needs. When the folded balloon 100 is folded along the axial compression, the interval of the two pressing plates 200 can be reduced, and when the interval of the two pressing plates 200 is less than the preset interval, the connecting buckle can lock the two pressing plates 200 to prevent the two pressing plates 200 from separating, so that the folded balloon 100 can be conveniently stored.

[0051] In some embodiments, as shown in Figure 4 The connecting buckle includes a male buckle 211.

[0052] The female buckle 212, the male buckle 211 and the female buckle 212 are respectively arranged on the opposite surfaces of the two pressing plates 200, and the male buckle 211 and the female buckle 212 are detachably connected.

[0053] The undocking button 213 is arranged on the female buckle 212, and the undocking button 213 is driven to move to separate the male buckle 211 from the female buckle 212.

[0054] In actual use, when the folded balloon 100 is folded along the axial compression, the two pressing plates 200 can be locked by the male buckle 211 and the female buckle 212 to prevent the two pressing plates 200 from separating; when the folded balloon 100 needs to be used, the male buckle 211 and the female buckle 212 can be separated by pressing the undocking button 213, at which time the two pressing plates 200 are separated, and the folded balloon 100 can be normally used.

[0056] In actual use, the face mask 400, the oxygen connecting pipe 510 and the oxygen storage bag 520 can be separated from the sealing cover 300, and then the sealing cover 300 is separated from the pressing plate 200, at which time the air cavity 110 of the folded balloon 100 is exposed, and flexible medical supplies such as the oxygen connecting pipe 510 can be placed in the air cavity 110, and then the sealing cover 300 is connected with the pressing plate 200, so that the air cavity 110 has a storage function when the folded balloon 100 is not used, and is convenient for medical staff to store. At the same time, since the folded balloon 100 can be folded to reduce the volume, objects such as cotton that can be easily compressed without affecting normal use can be placed in the air cavity 110, and then the folded balloon 100 is compressed to reduce the volume of the cotton, which is convenient for medical staff to better store the objects.
