[0029] The concept, specific structure and technical effects of the present invention will be clearly and completely described below in combination with the embodiments and drawings to fully understand the purpose, features and effects of the present invention.

[0030] Example 1

[0031] A portable lumbar external fixator, such as Figure 1-Figure 5 As shown, it includes a back panel 1, a support bar 2, a waist belt 3 and a storage bag 4;

[0032] The back panel 1 is made of a flexible material and has a plurality of support strips 2 vertically arranged inside. The back panel 1 is folded to have a plurality of support strips 2. The left and right ends of each back panel 1 are connected to a waist belt 3. When the plurality of back panels 1 are folded and unfolded, they fit outside the lumbar vertebrae of the patient's back. The waist belts 3 at the left and right ends of the back panel 1 are connected to each other in front of the patient's body. When the plurality of back panels 1 are folded and stored, the back panels 1 are placed in a storage bag 4.

[0033] In this embodiment, the back plate 1 can be set with a corresponding number of pieces according to actual needs, for example, the back plate 1 is folded to have two pieces, and the back plate 1 is folded to have four pieces. The height of one back plate 1 is about 10 cm. When it is two pieces, it is a normal version for general patients. When it is four pieces, it is an extended version for patients with particularly long stature, or when it is necessary to fix the upper and lower adjacent joints of the patient's lumbar spine. A lumbar external fixator with a corresponding number of back plates 1 can be selected according to the actual needs of the patient to meet the actual needs of the patient. In addition, the setting of the back plate 1 needs to be ergonomic to fit the patient's back.

[0034] In addition, the back panel 1 is foldable and can be folded vertically with each other. The back panel 1 is made of a flexible material so that it can fit on the outside of the patient's back lumbar spine, and use the vertical support bar 2 (the support bar 2 is a steel bar) inside it to support and assist in fixing the patient's lumbar spine. When it needs to be stored, since the back panel 1 is made of a flexible material, the back panel 1 can be folded horizontally. When storing, several back panels 1 are first folded vertically with each other, and then folded horizontally to reduce the volume of the back panel 1, and then the folded back panel 1 with a smaller volume is placed in the storage bag 4, so that the patient can carry it with them. For example, officers and soldiers carry it with them during daily exercise, and after exercise, they wear a lumbar external fixator to protect their lumbar spine.

[0035] like Figure 1 and 2 As shown, a hook 5 is provided on the back of the back plate 1, a hook hole 6 matching with the hook 5 is provided on the storage bag 4, and a small item placement cavity is also provided on the storage bag 4. In this embodiment, after the patient fixes the back plate 1 with the waist belt 3, that is, after wearing the lumbar external fixator, the hook hole 6 on the storage bag 4 can be hung on the hook 5 on the back plate 1, so that the storage bag 4 can be carried with the patient, so that it is convenient to place when storing. In addition, a small item placement cavity is also provided on the storage bag 4, which can be used to place small items such as mobile phones, freeing the hands and having the function of a waist bag.

[0036] In this embodiment, the waist belts 3 at the left and right ends of the back plate 1 are connected by Velcro to fix the back plate 1 on the patient.

[0037] In this embodiment, two adjacent back panels 1 are connected by a flexible connecting belt, so that the two adjacent back panels 1 can be folded with each other, thereby reducing their volume when stored.

[0038] In addition, since the two adjacent back plates 1 of this embodiment can be folded with each other, the fixing effect is not as good as that of the one-piece steel plate and the lumbar external fixator without folding function. However, although the one-piece steel plate has a good fixing effect, it is not very suitable because the patient cannot perform simple bending movements after wearing it. In this embodiment, the patient can perform simple bending movements after wearing it through the folding setting. Due to the function of the support strips 2 between each back plate 1 and the cooperation with the waist belt 3, the single back plate 1 and multiple back plates 1 of this embodiment also have the function of external vertebral fixation.

[0039] Example 2

[0040] This embodiment is further improved on the basis of embodiment 1, such as Figure 6 As shown, a bending sensor 7 is provided in the back panel 1 , the bending sensor 7 is connected to a controller 8 , and the controller 8 is connected to a reminder module 9 .

[0041] In the prior art, after wearing the lumbar external fixator, the patient still has a large bending behavior, and the existing lumbar external fixator has no safety reminder for the patient's bending angle. In this embodiment, a bending sensor 7 is provided, and the bending sensor 7 detects the patient's bending degree and sends the detection result to the controller 8. The controller 8 determines whether the patient has a large bending behavior based on the received bending detection data. When there is a large bending behavior, the controller sends a reminder signal to the reminder module 9, and the reminder module 9 emits a reminder sound to remind the patient that there is a large bending behavior and the patient needs to stop the large bending immediately to avoid the patient from hurting the body by the large bending.

[0042] In this embodiment, the bending sensor 7 can be a pressure sensor, which detects the pressure between the back plate 1 and the patient's back and transmits the pressure data to the controller 8. When the pressure data rises significantly, it means that the patient has a significant bending behavior. The controller 8 then sends a reminder signal to the reminder module 9, and the reminder module 9 reminds. The controller 8 can be a single-chip microcomputer for control; the reminder module 9 can be a speaker, which reminds the patient by playing sound.

[0043] like Figure 6 As shown, a heating therapy module 10 is provided in the back panel 1, and the heating therapy module 10 is connected to the controller 8, and the controller 8 is connected to a button module 11. The heating therapy module 10 is a conventional heating therapy module, which is started by the button module 11, and the controller 8 controls the heating therapy module 10 to start heating, so as to perform heating therapy on the patient's back.

[0044] like Figure 6 As shown, a timing module 12 is provided in the back panel 1, and the timing module 12 is connected to the controller 8. In the prior art, some patients wear lumbar external fixators for a long time, which causes a decrease in waist muscle strength or even muscle atrophy without any reminder. In this embodiment, after the lumbar external fixator is worn, the start button is pressed, and the controller 8 controls the timing module 12 to start timing. When the timing time is up, the timing module 12 sends a timing end signal to the controller 8. The controller 8 controls the reminder module 9 to sound according to the timing end signal to remind the patient that the wearing time is up and the lumbar external fixator needs to be taken off, so as to avoid the patient's waist muscle strength being decreased or even muscle atrophy due to long-term wearing of the lumbar external fixator.

[0045] like Figure 6 As shown, a power supply module 13 for powering is also provided in the back panel 1, and the power supply module 13 is used to power the bending sensor 7, the controller 8, the reminder module 9, the heating therapy module 10, the button module 11 and the timing module 12. The power supply module 13 can be a rechargeable battery.

[0046] In this embodiment, the back panel 1 can be set as a double layer, the bending sensor 7 and the heating therapy module 10 are arranged on the outside of the inner layer, the controller 8, the reminder module 9, the timing module 12 and the power supply module 13 are arranged between the double layers, and the button module 11 is arranged on the outside of the outer layer.

[0047] In order to better understand the present invention, the following is a complete description of the working principle of the present invention:

[0048] When in use, according to the actual needs of the patient, a lumbar external fixator with a corresponding number of back panels 1 is selected, for example, two or four panels, and then the selected lumbar external fixator is worn, the back panel 1 is folded and unfolded, and fits against the outside of the patient's lumbar spine. The belts 3 at the left and right ends of the back panel 1 are connected to each other in front of the patient to fix the back panel 1.

[0049] After wearing the lumbar external fixator, the patient can hang the hook hole 6 on the storage bag 4 on the hook 5 on the back plate 1 to carry the storage bag 4, so as to facilitate the storage. In addition, the storage bag 4 is also provided with a small item placement cavity, which can be used to place small items such as mobile phones, freeing hands and having the function of a waist bag.

[0050] After the patient wears the lumbar external fixator, the bending sensor 7 detects the patient's bending degree and sends the detection result to the controller 8. The controller 8 determines whether the patient has a large bending behavior based on the received bending detection data. If there is a large bending behavior, the controller sends a reminder signal to the reminder module 9. The reminder module 9 emits a reminder sound to remind the patient that there is a large bending behavior and the patient needs to stop bending immediately to avoid the patient hurting his body by bending too much.

[0051] After the patient wears the lumbar external fixator, the heating therapy is started by controlling the button module 11, and the controller 8 controls the heating therapy module 10 to start heating, thereby performing heating therapy on the patient's back.

[0052] After the patient wears the lumbar external fixator, he presses the start button to start the timing, and the controller 8 controls the timing module 12 to start timing. When the timing time is up, the timing module 12 sends a timing end signal to the controller 8. The controller 8 controls the reminder module 9 to make a sound according to the timing end signal to remind the patient that the wearing time is up and the lumbar external fixator needs to be taken off to avoid long-term wearing of the lumbar external fixator causing the patient's waist muscle strength to decrease or even muscle atrophy.

[0053] When the patient removes the lumbar external fixator, the waist belts 3 at the left and right ends of the back plate 1 are disconnected to separate the back plate 1 from the patient. The back plates 1 are then folded vertically and horizontally, and then placed in a storage bag 4 so that the patient can carry it with him.

[0054] The implementation methods of the present invention are described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalents or substitutions are all included in the scope defined by the claims of the present invention.
