Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a brace structure for a high-frequency vibration sputum drainage instrument. Background Art

[0002] High-frequency vibration sputum drainage instruments play an important role in the modern medical field. They usually use a sputum drainage vest as a key vibration component. When a patient needs to perform sputum drainage, they simply put on the sputum drainage vest normally, and then the instrument is started. High-frequency vibrations generated by the vest assist in sputum drainage, and the whole process is relatively convenient. Generally speaking, the sputum drainage vest needs to be inflated. Two groups of airbags are carefully designed on both sides of its back, and these two groups of airbags are located on both sides of the spine. Such a layout helps to transmit vibrations more evenly and effectively, thus better promoting sputum discharge. This sputum drainage method not only reduces the pain of patients compared to traditional manual sputum drainage but also greatly improves the efficiency of sputum drainage.

[0003] However, in actual use scenarios, some special situations will be encountered. Some patients are severely ill and have difficulty getting up after lying in bed for a long time. When they want to use a high-frequency vibration sputum drainage instrument for sputum drainage, they often need to operate while lying in bed. For example, by using an electric bed, the head of the bed is lifted to keep the patient in a specific posture to cooperate with sputum drainage. But problems also arise. Due to the action of the patient's own gravity, in this posture, the two groups of airbags that should be normally inflated on the back will be compressed and it is difficult to reach the ideal inflation state. Once the airbags are under-inflated, they cannot generate high-frequency vibrations of sufficient intensity, which directly leads to a significant reduction in the sputum drainage effect. This is undoubtedly an urgent problem to be solved for patients who urgently need sputum drainage to improve their breathing conditions.

[0004] Therefore, we propose a brace structure for a high-frequency vibration sputum drainage instrument to solve the problems raised above.

[0005] The above information disclosed in this background art is only used to increase the understanding of the background art of the present invention. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Invention

[0058] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. It should be noted that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size and illustrated. Any size is only exemplary and not limiting.

[0059] Embodiment 1:

[0060] Please refer to Figure 1 , a brace structure for a high-frequency vibration sputum drainage instrument, comprising: a curved bracket 1, arranged at one end of the electric bed that tilts upwards, including a bottom plate 11 and an arc-shaped head end 12 and an arc-shaped tail end 13 fixedly installed at both ends of the bottom plate 11. The shapes of the arc-shaped head end 12 and the arc-shaped tail end 13 respectively match the shapes of the transition regions between the cervical curvature and the thoracic curvature, and between the thoracic curvature and the lumbar curvature; a placement table 2, arranged at both ends of the bottom plate 11, and the connection points with the bottom plate 11 are respectively located below the arc-shaped head end 12 and the arc-shaped tail end 13; two rubber pillows 3, respectively arranged on the two placement tables 2; a rubber pad 4, arranged on the upper surfaces of the bottom plate 11, the arc-shaped head end 12 and the arc-shaped tail end 13.

[0061] The curved bracket 1 installed on the electric bed provides a supporting effect for the patient. Among them, the arc-shaped head end 12 and the arc-shaped tail end 13 respectively correspond to the transition regions between the cervical curvature and the thoracic curvature, and between the thoracic curvature and the lumbar curvature of the patient, and the bottom plate 11 corresponds to the position of the patient's spine. Specifically, when the electric bed tilts upwards, the curved bracket 1 can effectively support the patient's back, ensuring that the airbag of the sputum drainage vest can be normally inflated, and then generating high-frequency vibration to promote the discharge of sputum. This design not only improves the efficiency of sputum drainage but also greatly enhances the comfort of the patient.

[0062] First, install the curved support 1 at the end of the electric bed that tilts upward, ensuring that the arc-shaped head end 12 and the arc-shaped tail end 13 respectively match the transition areas between the cervical curvature and the thoracic curvature, and between the thoracic curvature and the lumbar curvature of the patient. Next, set the placement table 2 at both ends of the bottom plate 11, and place the rubber pillow 3 on the placement table to provide additional comfort. Finally, set the rubber pad 4 on the upper surfaces of the bottom plate 11, the arc-shaped head end 12, and the arc-shaped tail end 13 to increase the comfort of the patient. The principle is that through the supporting effect of the curved support 1, the compression of the sputum drainage vest airbag by the patient's own gravity is avoided, so as to ensure that the airbag can be normally inflated and generate high-frequency vibrations. This design effectively solves the problem of insufficient air inflation of the airbag caused by the patient's gravity during the traditional sputum drainage process, and significantly improves the sputum drainage effect. In practical applications, the brace structure is not only easy to operate, but also can be flexibly adjusted according to the specific situation of the patient.

[0063] Embodiment 2:

[0064] Please refer to Figures 2 - 5 , on the basis of Embodiment 1, it further includes an elastic adjusting member 6 for adjusting the support height, which is arranged between the bottom plate 11 and the rubber pad 4; installation grooves 14 are opened at both ends of the upper surface of the bottom plate 11; multiple groups of elastic adjusting members 6 are distributed in the installation grooves 14, and the installation direction of each elastic adjusting member 6 is perpendicular to the tangent of the upper surface of the bottom plate 11; the bottom plate 11 is provided with an array of height adjusting slots 5 for supporting the elastic adjusting members 6, which are arranged on both sides of the elastic adjusting member 6 and the number is adapted to the elastic adjusting member 6, and each array of height adjusting slots 5 includes a plurality of trapezoidal slots and is arranged along the installation direction of the elastic adjusting member 6 on the bottom plate 11; the bottom end of the elastic adjusting member 6 is inserted into the array of height adjusting slots 5.

[0065] Through this design, the support height can be flexibly adjusted according to the specific needs of the patient to ensure that the patient always maintains the most comfortable posture during sputum drainage.

[0066] The elastic adjusting member 6 includes: an arc-shaped support block 61 with an arc-shaped upper surface; a limiting groove 62 opened on the bottom surface of the arc-shaped support block 61; fixed shafts 63 fixed on both sides of the arc-shaped support block 61 and located in the limiting groove 62; a lateral support bar 64 rotatably connected to the fixed shafts 63; a torsion spring 65 is sleeved on the fixed shaft 63, and the two feet of the torsion spring 65 are respectively in contact with the arc-shaped support block 61 and the lateral support bar 64; a limiting block 66 is also fixedly installed on the lateral support bar 64, and the limiting block 66 is in contact with the bottom surface of the arc-shaped support block 61; the lateral support bar 64 is inserted into the array of height adjusting slots 5.

[0067] When the above technical solution is in use, the principle of adjusting the elastic adjusting member 6 is as follows: First, the operator presses the lateral support bar 64, and the elastic potential energy of the torsion spring 65 increases. At the same time, the elastic adjusting member 6 is pulled outwards, so that the bottom end of the lateral support bar 64 leaves the array height adjustment slot 5. Then, the operator can select one of the trapezoidal slots at a certain position in the array height adjustment slot 5 according to different positions. Then, the operator releases the elastic adjusting member 6, and the lateral support bar 64 resets under the action of the torsion spring 65.

[0068] The supporting ability of the elastic adjusting member 6 depends on the lateral support bar 64. When the lateral support bar 64 provides a supporting function, its own stability is maintained through the limiting action of the limiting block 66. And multiple groups of elastic adjusting members 6 are provided, and the gravity of the patient is distributed to these elastic adjusting members 6.

[0069] Embodiment 3:

[0070] Please refer to Figures 6 - 7 , on the basis of Embodiment 1 or Embodiment 2, it further includes a fixing member 7, which is arranged on the placing table 2; the bottom plate 11 is rotatably connected to the arc-shaped head end 12 and the arc-shaped tail end 13, and is fastened by the fixing member 7.

[0072] By adopting the above technical solution, when it is necessary to adjust the angles of the placing tables 2 at both ends during use to better adapt to the body shape of the patient,

[0073] For the placing table 2 at the head end: First, the operator pulls out the pull rod 71 from one of the limiting holes 9, the spring 72 is compressed, and then the placing table 2 is rotated. After releasing the pull rod 71, the end of the pull rod 71 is inserted into one of the limiting holes 9.

[0074] For the placing table 2 at the tail end: It is necessary for the placing table at the tail end to be in full contact with the hospital bed. First, the operator pulls out the pull rod 71 from one of the limiting holes 9, the spring 72 is compressed, and then the bottom plate 11 is rotated. After releasing the pull rod 71, the end of the pull rod 71 is inserted into one of the limiting holes 9.
