DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 7 As shown, the present invention provides an adjustable lung function breathing rehabilitation training device, including an outer box 1, a cylinder 2 is fixedly connected to one side of the outer box 1, a rotating cylinder 3 and a clamping assembly 14 are movably connected inside the cylinder 2, a gear 4 is fixedly connected to the rotating cylinder 3 on the side close to the outer box 1, a limiting groove 5 is provided at an equal angle in an annular manner on the side of the rotating cylinder 3 away from the gear 4, a plurality of baffle assemblies 6 matched with the limiting groove 5 are movably connected inside the cylinder 2, a tooth plate 7 and a first inclined block 10 are movably connected inside the outer box 1, four first clamping grooves 8 are provided at equal distances on the side of the tooth plate 7 away from the gear 4, a detection assembly 12 is arranged on the top of the outer box 1, an auxiliary assembly 13 is clamped on one end of the cylinder 2 away from the outer box 1, a second inclined block 15 is provided at an equal angle of 72 degrees inside the cylinder 2, and a second round rod 17 is fixedly connected to the second inclined block 15 on the side close to the clamping assembly 14;

[0030] The baffle assembly 6 includes a triangular plate 601, and two sides of the triangular plate 601 are respectively fixedly connected with a clamping block 602 and a first round rod 603;

[0031] The auxiliary component 13 includes a sleeve 1301 , and a breathing tube 1302 is fixedly connected to the inner wall of the sleeve 1301 .

[0032] The above scheme is adopted: both sides of the first inclined block 10 are inclined, which is used to facilitate the up and down movement of the tooth plate 7. Four first slots 8 are opened in the tooth plate 7, so as to facilitate the limiting of the moving distance of the tooth plate 7. Through the design of the limiting slot 5, the rotation of the rotating drum 3 can drive the triangular plate 601 to move, thereby increasing the cross-sectional area of ​​gas circulation, thereby reducing the resistance of gas circulation, making the patient's breathing process easier, so that the device can be adapted to different patients.

[0033] like Figures 4 to 5 As shown, the first round rod 603 is movably connected to the inside of the limiting groove 5, and the inner wall of the cylinder 2 is provided with a slide groove 604 that cooperates with the block 602. There are seven triangular plates 601. After the seven triangular plates 601 abut against each other, a hole will be formed at the center end. When the rotating drum 3 rotates, it will drive the first round rod 603 to slide along the track of the limiting groove 5. After the first round rod 603 slides, it will drive the triangular plate 601 to move along the direction of the slide groove 604. After the seven triangular plates 601 move, the hole at the center end will gradually increase.

[0034] The above scheme is adopted: seven triangular plates 601 are abutted against each other. Its function is that in the respiratory rehabilitation training device, the gas usually flows under a certain pressure difference, and when the gas flows from the high-pressure area to the low-pressure area, it will choose the path with the least resistance. At this time, since several triangular plates 601 abut against each other, the abutment parts have good sealing properties, and it is difficult for the gas to leak out from the gaps between the triangular plates 601, so that the gas chooses to pass through the middle hole, which is a path with relatively small resistance.

[0035] like Figure 1 to Figure 2 , Figure 5 As shown, the gear 4 is meshed and connected with the tooth plate 7, and a pull rod 9 is fixedly connected to one side of the tooth plate 7. The pull rod 9 passes through the outer wall of the outer box 1 and extends to the outside of the outer box 1. The first inclined block 10 is initially inserted into the inside of the first card slot 8 at the bottom. The upper and lower sides of the first inclined block 10 are both inclined. The side of the first inclined block 10 away from the tooth plate 7 is fixedly connected with a first spring piece 11. The first spring piece 11 is used to squeeze the first inclined block 10 and keep the first inclined block 10 moving toward the tooth plate 7. The detection component 12 includes an instrument panel 1201, and a pressure sensor 1202 is arranged inside the instrument panel 1201. Pointers 1203 are arranged on both sides of the instrument panel 1201. The bottom of the instrument panel 1201 is connected to the inner cavity of the outer box 1.

[0036] The above scheme is adopted: the first inclined block 10 is inserted into the first slot 8. Its function is that since the first slots 8 are equidistantly arranged on the tooth plate 7, when the tooth plate 7 moves downward, the inclined block can select different slots for insertion, thereby realizing multi-gear adjustment, thereby making the resistance adjustment inside the device more flexible and convenient.

[0037] like Figures 1 to 3 , Figure 7 As shown, the end of the breathing tube 1302 away from the sleeve 1301 is clamped with a mouthpiece 1303, and the outer wall of the sleeve 1301 is provided with a second groove 1304 in a 72-degree ring. The second inclined block 15 passes through the outer wall of the cylinder 2 and extends to the outside of the cylinder 2. The second inclined block 15 is initially clamped into the inside of the second groove 1304. One side of the second inclined block 15 is in a slope shape. The end of the second inclined block 15 away from the auxiliary component 13 is fixedly connected with a third elastic piece 16, and the third elastic piece 16 is fixedly connected to the outer box 1. The third elastic piece 16 is used to squeeze the second inclined block 15 and keep the second inclined block 15 moving toward the sleeve 1301.

[0038] The above scheme is adopted: through the design of the third spring piece 16, its function is that when the auxiliary component 13 is replaced or cleaned, at this time, by inserting one end of the sleeve 1301 into the interior of the cylinder 2, the sleeve 1301 is abutted against the inclined surface of the second inclined block 15, and the second inclined block 15 is squeezed to shrink into the cylinder 2. When the sleeve 1301 moves to a predetermined position, at this time, the second inclined block 15 will be reset under the action of the elastic force of the third spring piece 16, so as to be stuck in the interior of the second slot 1304, and then fix the position of the sleeve 1301, thereby achieving the effect of facilitating the installation of the auxiliary component 13.

[0039] like Figure 6 to Figure 7 As shown, the clamping assembly 14 includes a turntable 1401, and a guide groove 1402 is provided on the surface of the turntable 1401 at an annular and equiangular manner. The second round rod 17 is movably clamped in the guide groove 1402. One end of the outer wall of the turntable 1401 is fixedly connected with a second elastic piece 1403. The turntable 1401 is elastically connected to the cylinder 2 through the second elastic piece 1403. The side of the turntable 1401 away from the rotating cylinder 3 is fixedly connected with a convex rod 1404. The convex rod 1404 penetrates the outer wall of the cylinder 2 and extends to the outside of the cylinder 2. The inner wall of the cylinder 2 is provided with a straight groove for circumferentially limiting the third elastic piece 16.

[0040] The above scheme is adopted: one side of the second inclined block 15 is inclined, so that the sleeve 1301 can squeeze the second inclined block 15 to shrink into the inside of the cylinder 2, thereby achieving the purpose of facilitating the installation of the auxiliary component 13 on the cylinder 2; through the cooperation between the second round rod 17 and the guide groove 1402, when the turntable 1401 rotates, the second round rod 17 drives the second inclined block 15 to shrink into the cylinder 2, thereby releasing the second inclined block 15 from the sleeve 1301, thereby facilitating the removal of the auxiliary component 13 from the inside of the cylinder 2, and then facilitating the medical staff to replace and clean the auxiliary component 13, thereby improving the overall convenience and practicality of the device.

[0041] The working principle and use process of the present invention are as follows: when it is necessary to adjust the resistance of the respiratory rehabilitation training device, the operator pulls the pull rod 9 downward to drive the toothed plate 7 fixed thereon to move downward, and then the toothed plate 7 is meshed with the gear 4, so that the toothed plate 7 drives the rotating drum 3 to rotate through the gear 4 during the downward movement. While the rotating drum 3 rotates, the first round rod 603 is driven to slide along the trajectory of the limiting groove 5, thereby driving the triangular plate 601 and the block 602 to move through the first round rod 603. Subsequently, since the block 602 is movably engaged in the inside of the slide groove 604, the first round rod 603 drives the triangular plate 601 to move and rotate along the direction of the slide groove 604 when sliding. After the seven triangular plates 601 move, the diameter of the hole at the central end thereof will gradually increase, thereby increasing the cross-sectional area of ​​gas circulation, so that the gas flow generated by the patient's exhalation or inhalation is more dispersed, and then the pressure distribution is more uniform, which is conducive to reducing the patient's exhalation or inhalation resistance;

[0042] When the tooth plate 7 moves downward, it will abut against the inclined surface of the first inclined block 10, thereby squeezing the first inclined block 10 to move in the direction of the first elastic sheet 11, so that the first inclined block 10 is disengaged from the inside of the first slot 8 and is released from the tooth plate 7. When the tooth plate 7 moves downward for a certain distance, the first inclined block 10 is clamped into the inside of another first slot 8 under the action of the elastic force of the first elastic sheet 11, thereby re-engaging with the tooth plate 7 and fixing the position of the tooth plate 7. When it is necessary to reduce the resistance of the respiratory rehabilitation training device, the operator continues to pull the tooth plate 7 downward until the first inclined block 10 is clamped into the inside of the topmost first slot 8;

[0043] Then the patient puts the mouthpiece 1303 into his mouth and exhales into the breathing tube 1302 through the mouthpiece 1303. The gas exhaled by the patient enters the outer box 1 through the hole at the center end of the triangle plate 601. Then the gas inside the outer box 1 enters the instrument panel 1201. The pressure of the exhaled gas is detected by the pressure sensor 1202 provided inside the instrument panel 1201. The signal and data are transmitted to the pointer 1203 after processing. Then the data is converted into the rotation angle of the pointer 1203, thereby driving the pointer 1203 to rotate to a predetermined scale, so as to facilitate real-time monitoring of the gas exhaled by the patient.

[0044] When the breathing tube 1302 and the mouthpiece 1303 need to be cleaned, the convex rod 1404 is pulled to drive the turntable 1401 to rotate. While the turntable 1401 rotates, the second round rod 17 is driven to slide along the trajectory of the guide groove 1402. Since the inner wall of the cylinder 2 is provided with a straight groove for circumferentially limiting the second round rod 17, the turntable 1401 can only drive the second inclined block 15 to move away from the sleeve 1301 through the second round rod 17 during rotation. When the convex rod 1404 abuts against the outer wall of the cylinder 2, the second round rod 17 drives the second inclined block 15 to completely retract into the interior of the cylinder 2, thereby releasing the second inclined block 15 from the clamping connection with the sleeve 1301, thereby facilitating the operator to peel off the auxiliary component 13 as a whole from the interior of the cylinder 2 for subsequent cleaning work.
