Detailed implementation manners

[0032] The first embodiment of the present application is as follows:

[0033] Please refer to Figures 1-6 , wherein, Figure 1 It is a schematic structural diagram of the first embodiment of the present invention. Figure 2 It is a front view of the first embodiment of the present invention. Figure 3 is Figure 2 A partial enlarged view of detail A. Figure 4 It is a left view of the first embodiment of the present invention. Figure 5 is Figure 4 A partial enlarged view of detail B. Figure 6 Figure 4 A sectional view along the A-A direction.

[0034] The present invention provides a pulmonary function rehabilitation physiotherapy device, which includes a base 1; and also includes a training component; the training component includes a mounting frame 2, a U-shaped tube 3, a piston 4, a connecting rod 5, a pushing block 6, a lower elastic resistance mechanism 7, a bracket 8, an upper elastic resistance mechanism 9, a connecting pipe 10 and a breathing head 11; the training component further includes a pointer 12 and two indicating plates 13; the mounting frame 2 includes two columns 21 and a mounting block 22; the lower elastic resistance mechanism 7 includes two mounting ears 71, two first mounting rods 72, two first limiting discs 73, a first sliding plate 74, a first adjusting plate 75, two first springs 76 and a first adjusting member 77; the U-shaped tube 3 has an external thread 31; the first adjusting member 77 includes two sliding rods 771, a top ring 772 and a first knob 773; the upper elastic resistance mechanism 9 includes a mounting plate 91, two second mounting rods 92, two second limiting discs 93, a second sliding plate 94, a second adjusting plate 95, two second springs 96 and a second adjusting member 97; the second adjusting member 97 includes a screw rod 971 and a second knob 972; through the foregoing solution, both blowing training and inhaling training can be carried out, improving the rehabilitation training effect.

[0035] Further, the mounting frame 2 is fixedly arranged on the top of the base 1; the U-shaped tube 3 is fixedly arranged on the mounting frame 2; the piston 4 is slidably arranged in the U-shaped tube 3; the connecting rod 5 is fixedly arranged on the top of the piston 4; the pushing block 6 is fixedly arranged on the top of the connecting rod 5; the lower elastic resistance mechanism 7 is arranged on the U-shaped tube 3 and is located below the pushing block 6; the bracket 8 is fixedly arranged on the U-shaped tube 3; the upper elastic resistance mechanism 9 is arranged on the bracket 8 and is located above the pushing block 6; the connecting pipe 10 is communicatively arranged on one side of the U-shaped tube 3; the breathing head 11 is communicatively arranged on one side of the connecting pipe 10.

[0036] In this embodiment, the mounting bracket 2 is used to fixedly mount the U-shaped tube 3. A piston 4 is slidably disposed inside the U-shaped tube 3. When the piston 4 slides, it drives the push block 6 to move up and down through the connecting rod 5. When the push block 6 rises, the upper elastic resistance mechanism 9 provides resistance. When the push block 6 descends, the lower elastic resistance mechanism 7 provides resistance. When the user bites the breathing head 11 and blows air, the piston 4 slides upward. When inhaling, the piston 4 slides downward. When performing blowing training, the user can first take a deep breath, then bite the breathing head 11 and blow air into the U-shaped tube 3. The piston 4 slides upward, driving the push block 6 to rise through the connecting rod 5. When the push block 6 rises, it is resisted by the upper elastic resistance mechanism 9, adding a certain intensity to the user's blowing training. When performing inhalation training, the user can first exhale, then bite the breathing head 11 and start inhaling. The piston 4 slides downward, driving the push block 6 to descend through the connecting rod 5. When the push block 6 descends, it is resisted by the lower elastic resistance mechanism 7, adding a certain intensity to the user's inhalation training. Thus, both blowing training and inhalation training can be carried out, improving the rehabilitation training effect.

[0037] Further, the training assembly further includes a pointer 12 and two indicator plates 13.

[0038] The pointer 12 is fixedly disposed on one side of the push block 6. The two indicator plates 13 are respectively fixedly disposed on the bracket 8.

[0039] In this embodiment, the two indicator plates 13 are respectively located above and below the pointer 12, and the pointer 12 moves up and down synchronously with the push block 6. During blowing training, the push block 6 rises, driving the pointer 12 to move upward. As long as the pointer 12 touches the upper indicator plate 13, it means reaching the standard and blowing can be stopped. During inhalation training, the push block 6 descends, driving the pointer 12 to move downward. As long as the pointer 12 touches the lower indicator plate 13, it means reaching the standard and inhalation can be stopped.

[0040] Further, the mounting bracket 2 includes two columns 21 and a mounting block 22.

[0041] The two columns 21 are respectively fixedly disposed on the top of the base 1. The mounting block 22 is fixedly connected to the U-shaped tube 3 and is respectively fixedly connected to the two columns 21 and is located at the top of the two columns 21.

[0042] In this embodiment, the two columns 21 support the mounting block 22. Two holes are provided on the mounting block 22 for mounting the U-shaped tube 3.

[0043] Further, the lower elastic resistance mechanism 7 includes two mounting ears 71, two first mounting rods 72, two first limiting discs 73, a first sliding plate 74, a first adjusting plate 75, two first springs 76 and a first adjusting member 77;

[0044] The two mounting ears 71 are respectively fixedly arranged on the U-shaped tube 3; the two first mounting rods 72 are respectively fixedly arranged on the tops of the two mounting ears 71; the two first limiting discs 73 are respectively fixedly arranged on the tops of the two first mounting rods 72; the first sliding plate 74 is slidably arranged on the two first mounting rods 72 and is penetrated by the two first mounting rods 72; the first adjusting plate 75 is slidably arranged on the two first mounting rods 72 and is penetrated by the two first mounting rods 72 and is located below the first sliding plate 74; the two first springs 76 are respectively sleeved on the two first mounting rods 72 and are located between the first sliding plate 74 and the first adjusting plate 75; the first adjusting member 77 is arranged below the first adjusting plate 75 and is used for driving the first adjusting plate 75 to slide.

[0045] In this embodiment, the two mounting ears 71 fixedly mount the two first mounting rods 72, and the two first limiting discs 73 are used to limit the first sliding plate 74 to prevent the first sliding plate 74 from being pushed out of the two first springs 76; during inspiration training, the piston 4 slides down, drives the push block 6 to descend through the connecting rod 5, the push block 6 presses the first sliding plate 74, the first sliding plate 74 slides down along the two first mounting rods 72, compresses the two first springs 76, and the two first springs 76 give an elastic resistance to the push block 6 to provide a certain training intensity; there is an opening in the center of the first sliding plate 74 for the connecting rod 5 to pass through; when it is necessary to increase the training intensity, the first adjusting member 77 is used to drive the first adjusting plate 75 to slide upwards, so that in the initial state, the distance between the first adjusting plate 75 and the first sliding plate 74 is shortened, the two first springs 76 are compressed tighter, the initial elastic force is greater, and since the pointer 12 needs to touch the lower indicating plate 13 during each inspiration training, the descending distance of the push block 6 is also fixed, and the tighter the two first springs 76 are compressed in the initial state, the greater the elastic resistance the push block 6 receives when compressing the two first springs 76 again, so the inspiration training intensity will become greater; therefore, in the initial state before training, the shorter the distance between the first adjusting plate 75 and the first sliding plate 74, the greater the intensity during inspiration training.

[0046] Further, the U-shaped tube 3 has an external thread 31; the first adjusting member 77 includes two sliding rods 771, a top ring 772 and a first knob 773;

[0047] The two sliding rods 771 are respectively fixedly connected to the first adjusting plate 75, respectively slidably connected to the two mounting ears 71, and respectively pass through the two mounting ears 71; the top ring 772 is fixedly arranged at the bottoms of the two sliding rods 771; the first knob 773 is threadedly connected to the U-shaped tube 3 and is located below the top ring 772.

[0048] In this embodiment, the external thread 31 is used for threadedly mounting the first knob 773. By rotating the first knob 773, it can move up and down. Therefore, when the first knob 773 rotates upward, the first knob 773 pushes up the top ring 772, and the top ring 772 pushes up the first adjusting plate 75 through the two sliding rods 771. When the first knob 773 rotates downward, the two first springs 76 push the adjusting plate to slide downward.

[0049] Furthermore, the upper elastic resistance mechanism 9 includes a mounting plate 91, two second mounting rods 92, two second limiting discs 93, a second sliding plate 94, a second adjusting plate 95, two second springs 96 and a second adjusting member 97;

[0050] The mounting plate 91 is fixedly arranged on one side of the bracket 8; the two second mounting rods 92 are respectively fixedly arranged at the bottom of the mounting plate 91; the two second limiting discs 93 are respectively fixedly arranged at the bottoms of the two second mounting rods 92; the second sliding plate 94 is slidably arranged on the two second mounting rods 92 and is penetrated by the two second mounting rods 92; the second adjusting plate 95 is slidably arranged on the two second mounting rods 92 and is penetrated by the two second mounting rods 92 and is located above the second sliding plate 94; the two second springs 96 are respectively sleeved on the two second mounting rods 92 and are located between the second sliding plate 94 and the second adjusting plate 95; the second adjusting member 97 is arranged above the second adjusting plate 95 and is used for driving the second adjusting plate 95 to slide.

[0051] In this embodiment, the mounting plate 91 is used to fixedly mount two second mounting rods 92, and two second limiting discs 93 are used to limit the second sliding plate 94 to prevent the second sliding plate 94 from being pushed out and disengaged by the two second springs 96; during the blowing training, the piston 4 slides upward, drives the push block 6 to rise through the connecting rod 5, the push block 6 pushes up the second sliding plate 94, and the second sliding plate 94 slides upward along the two second mounting rods 92, compressing the two second springs 96, and the two second springs 96 then give the push block 6 an elastic resistance to provide a certain training intensity; when it is necessary to increase the training intensity, the second adjusting member 97 is used to drive the second adjusting plate 95 to slide downward, so that in the initial state, the distance between the second adjusting plate 95 and the second sliding plate 94 is shortened, the two second springs 96 are compressed tighter, and the initial elastic force will be greater. And since the pointer 12 needs to touch the upper indicator board 13 during each blowing training, the rising distance of the push block 6 is also fixed. The tighter the two second springs 96 are compressed in the initial state, the greater the elastic resistance the push block 6 will receive when it compresses the two second springs 96 again. Therefore, the training intensity of blowing will become greater; therefore, in the initial state when not trained, the shorter the distance between the second adjusting plate 95 and the second sliding plate 94, the greater the intensity during the blowing training.

[0052] Further, the second adjusting member 97 includes a screw rod 971 and a second knob 972;

[0053] The screw rod 971 is rotatably connected to the second adjusting plate 95, threadedly connected to the mounting plate 91, and passes through the mounting plate 91; the second knob 972 is fixedly arranged at the top of the screw rod 971.

[0054] In this embodiment, the second knob 972 is used to conveniently rotate the screw rod 971, and the screw rod 971 can drive the second adjusting plate 95 to lift and slide.

[0055] A pulmonary function rehabilitation physiotherapy device according to this embodiment. The mounting bracket 2 is used for fixedly mounting the U-shaped tube 3. A piston 4 is slidably arranged inside the U-shaped tube 3. When the piston 4 slides, it drives the push block 6 to move up and down through the connecting rod 5. When the push block 6 rises, the upper elastic resistance mechanism 9 provides resistance. When the push block 6 descends, the lower elastic resistance mechanism 7 provides resistance. When the user bites the breathing head 11 and blows air, the piston 4 slides upward. When inhaling, the piston 4 slides downward. During the blowing training, the user can take a deep breath first, then bite the breathing head 11 and blow air into the U-shaped tube 3. The piston 4 slides upward, driving the push block 6 to rise through the connecting rod 5. When the push block 6 rises, it is resisted by the upper elastic resistance mechanism 9, increasing the intensity of the user's blowing training to a certain extent. During the inhalation training, the user can exhale first, then bite the breathing head 11 and start inhaling. The piston 4 slides downward, driving the push block 6 to descend through the connecting rod 5. When the push block 6 descends, it is resisted by the lower elastic resistance mechanism 7, increasing the intensity of the user's inhalation training to a certain extent. Thus, both blowing training and inhalation training can be carried out, improving the rehabilitation training effect.
