Description

Technical Field

[0001] The utility model relates to medical equipment, in particular to a portable cervical vertebra traction device. Background Art

[0002] The portable cervical traction device based on the airbag structure is easy to carry and can be stacked well after being deflated, saving space and being very light. However, since the airbag generates an upward traction force to traction the cervical spine after being inflated, the main action site is the front chin area rather than the cervical spine area. During traction, the human body curve remains straight behind the neck, and the material of the inflatable cervical traction device is relatively soft, so the upward traction force on the neck is not large. Therefore, the traction force is evenly upward regardless of the front, back, left, and right, and the traction effect is not ideal. Utility Model Content

[0003] The utility model aims to provide a portable cervical traction device to solve the problems existing in the above-mentioned prior art.

[0004] The utility model discloses a portable cervical traction device, comprising a first airbag assembly, a second airbag assembly and a third airbag assembly which are connected end to end to form a superior arc; the first airbag assembly comprises a first shoulder top airbag, a first expansion airbag group and a first submandibular airbag which are fixedly connected in sequence from bottom to top; wherein the first expansion airbag group is formed by stacking multiple layers of airbags which are independent of each other; the second airbag assembly comprises a second shoulder top airbag, a second expansion airbag group and a second submandibular airbag which are fixedly connected in sequence from bottom to top; wherein the second expansion airbag group is formed by stacking multiple layers of airbags which are independent of each other; the third airbag assembly comprises a third shoulder top airbag, a third expansion airbag group and a third submandibular airbag which are fixedly connected in sequence from bottom to top; wherein the third expansion airbag group is formed by stacking multiple layers of airbags which are independent of each other; the second shoulder top airbag is fixedly connected to the first shoulder top airbag and the third shoulder top airbag respectively; the second expansion airbag group is fixedly connected to the first expansion airbag group and the third expansion airbag group respectively; each airbag is provided with an independent air valve.

[0005] The first expandable airbag group, the second expandable airbag group and the third expandable airbag group have the same number of stacked layers, which is four to six layers, preferably five layers.

[0006] The diameters of the first shoulder top airbag, the first submandibular airbag, the second shoulder top airbag, the second submandibular airbag, the third shoulder top airbag and the third submandibular airbag are the same. The diameters of each airbag in the first expansion airbag group, the second expansion airbag group and the third expansion airbag group are the same and smaller than the first shoulder top airbag.

[0007] There are gaps between the second expandable airbag group and the first expandable airbag group and the third expandable airbag group respectively.

[0008] All the air valves in the first airbag assembly are distributed with equal arcs around the center of the major arc. All the air valves in the second airbag assembly are distributed with equal arcs around the center of the major arc. All the air valves in the third airbag assembly are distributed with equal arcs around the center of the major arc.

[0009] The portable cervical traction device described in the utility model has the advantage that the stacked expansion airbag group can adjust different traction forces according to actual needs. While maintaining the portability of the airbag structure, it ensures that the upward traction is uniform in the front, back, left and right directions, thereby improving the traction effect.

[0020] like Figures 1 to 6As shown, the portable cervical traction device described in the utility model comprises a first airbag assembly 10, a second airbag assembly 20 and a third airbag assembly 30 connected end to end to form a superior arc; the first airbag assembly 10 comprises a first shoulder top airbag 11, a first expansion airbag group 12 and a first submandibular airbag 13 fixedly connected in sequence from bottom to top; wherein the first expansion airbag group 12 is formed by stacking multiple layers of independent airbags; the second airbag assembly 20 comprises a second shoulder top airbag 21, a second expansion airbag group 22 and a second submandibular airbag 23 fixedly connected in sequence from bottom to top; wherein The second expandable airbag group 22 is formed by stacking multiple layers of independent airbags; the third airbag assembly 30 includes a third shoulder airbag 31, a third expandable airbag group 32 and a third submandibular airbag 33 which are fixedly connected in sequence from bottom to top; wherein the third expandable airbag group 32 is formed by stacking multiple layers of independent airbags; the second shoulder airbag 21 is fixedly connected to the first shoulder airbag 11 and the third shoulder airbag 31 respectively; the second expandable airbag group 22 is fixedly connected to the first expandable airbag group 12 and the third expandable airbag group 32 respectively; each airbag is provided with an independent air valve 41.

[0021] The first expandable airbag group 12 , the second expandable airbag group 22 and the third expandable airbag group 32 are stacked in the same number of layers, which is four to six layers, preferably five layers.

[0022] The diameters of the first shoulder top airbag 11, the first submandibular airbag 13, the second shoulder top airbag 21, the second submandibular airbag 23, the third shoulder top airbag 31 and the third submandibular airbag 33 are the same. The diameters of each airbag in the first expansion airbag group 12, the second expansion airbag group 22 and the third expansion airbag group 32 are the same and smaller than the first shoulder top airbag 11. The diameter of the airbags in the expansion airbag group is small, so it is convenient to set multiple layers. The more layers there are, the easier it is to control the traction uniformity.

[0023] There are gaps between the second expansion airbag group 22 and the first expansion airbag group 12 and the third expansion airbag group 32, respectively, to prevent the middle part of the portable cervical traction device from being squeezed by each other and expanding outward laterally to affect the overall stability.

[0024] All the air valves 41 in the first airbag assembly 10 are distributed with equal arcs at the center of the major arc. All the air valves 41 in the second airbag assembly 20 are distributed with equal arcs at the center of the major arc. All the air valves 41 in the third airbag assembly 30 are distributed with equal arcs at the center of the major arc. The projection positions of all the air valves 41 on the plane perpendicular to the central axis are all staggered, so as to improve the storage convenience of all the airbags after they are deflated.

[0025] The working process of a portable cervical traction device described in the utility model is as follows: an external air pump completely inflates the first shoulder top airbag 11, the second shoulder top airbag 21, the third shoulder top airbag 31, the first submandibular airbag 13, the second submandibular airbag 23 and the third submandibular airbag 33, and the human neck enters the internal space of the portable cervical traction device from the superior arc opening between the first airbag assembly 10 and the third airbag assembly 30. According to the individual condition and traction needs of the patient, all or part of the airbags in the first expansion airbag group 12, the second expansion airbag group 22 and the third expansion airbag group 32 are selectively inflated, and any inflated airbag can be selectively fully inflated or partially inflated. All submandibular airbags support the human mandible at the required pressure. After use, the corresponding airbags can be stored by simply deflating them using each air valve.

[0026] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
