Description

Technical Field

[0001] The invention relates to the technical field of respiratory training equipment, in particular to a respiratory training correction device used after fracture surgery. Background Art

[0002] Respiratory function is one of the important life support systems of the human body. It continuously inhales fresh air and expels turbid air, expelling the old and taking in the new, to achieve gas exchange between the body and the external environment to maintain human life activities. However, for patients after fracture surgery, the pain caused by surgery, limited movement, and possible decreased respiratory muscle function often lead to abnormal respiratory rate and depth.

[0003] As a non-invasive, low-cost rehabilitation method, breathing training is a method to ensure airway patency, improve respiratory muscle function, promote sputum discharge and drainage, and enhance gas exchange efficiency. In order to improve the effect of breathing training and ensure the respiratory status of patients after surgery, breathing training equipment is often used to assist in training correction.

[0004] At present, the respiratory training correction for patients after fracture surgery mainly uses balloons or breathing trainers for breathing training. However, balloons cannot adjust the resistance during breathing (resistance of exhalation and / or inhalation), and cannot be flexibly adjusted according to the recovery of the patient's respiratory muscle strength; although breathing trainers can adjust the resistance by adjusting the number of springs, their structure is complex and inconvenient to operate; and both are difficult to control the uniformity of breathing training, resulting in uneven training effects, and may even have an adverse effect on rehabilitation.

[0010] Furthermore, an hourglass assembly is connected to the inner side of the shell, and the hourglass assembly includes a windmill and a pair of cones. The windmill is rotatably connected to the shell, and the pair of cones contains a flowing medium. A ball valve for controlling the connection and / or closing thereof is connected between the pair of cones, and the operating shaft of the ball valve is fixedly connected to the rotating shaft of the windmill; the fixed plate is provided with an air guide hole arranged in cooperation with the windmill.

[0017] The principle and beneficial effects of the technical solution are:

[0018] 1. The present invention provides a breathing training and correction device for post-operation of fracture. The breathing mask and the shell are connected by an airway. The patient blows air into the shell through the breathing mask. The inner side of the shell is fixedly connected to a fixing plate and a fixing groove. The fixing plate is connected to a linkage plate slidably connected to the fixing groove through a second spring. The air blocking plate is connected to the linkage plate. When the patient exhales, the air blocking plate is affected by the gas to overcome the force of the second spring and moves toward a side away from the airway. When the patient inhales, the air blocking plate is reset under the action of the second spring. By repeating this process, periodic breathing training can be performed. Among them, a rack that is fixedly connected to the linkage member and slidably connected to the fixed groove body is connected to the inner side of the shell, and the rack is meshed with the gear. During the breathing training process, the gas exhaled by the patient acts on the air blocking plate, the air blocking plate acts on the linkage plate, the linkage plate acts on the rack, and the rack acts on the gear. A uniform component that controls its uniform rotation is connected to the gear, so that the rack, the linkage plate and the air blocking plate rotate uniformly, thereby achieving the uniformity of the breathing training correction process, following the scientific nature of breathing training correction, and improving the effect of breathing training correction; an internal threaded cylinder is connected in the shell, an external thread is set on the airway tube, and the airway tube is rotated so that it moves along the inner thread under the action of the thread. The axial movement of the threaded barrel can adjust the distance between its air outlet and the air blocking plate, so that when the patient exhales gas of the same intensity, the air blocking plate is subjected to different forces. To ensure that the air blocking plate can still achieve the same reciprocating motion when the distance between the air blocking plate and the air outlet of the airway is different, the patient's exhalation intensity must be adjusted to adjust the breathing resistance. The effect of adjusting the breathing training resistance is good, and the operation is convenient and quick. The shell is made of transparent material, which is convenient for observing the distance between the air outlet of the airway and the air blocking plate, and for observing the movement of the air blocking plate, linkage, rack, gear, etc. during the breathing training process, thereby increasing the interest of the breathing training.

[0019] 2. The present invention provides a breathing training and correction device for fracture surgery. The uniform component adopts a structure of a linkage disk, a fixed ratchet, a pawl and a tension spring. The fixed ratchet is fixedly connected to the fixed plate, and the linkage disk is coaxially fixedly connected to the gear. When the air blocking plate moves, the linkage disk rotates accordingly under the action of the linkage plate, the rack and the gear. When the linkage disk rotates uniformly and smoothly, the tension spring and the pawl rotate with the rotation of the linkage disk. When the gear rotates unevenly (suddenly accelerates or suddenly decelerates), the pawl is subjected to the action of centrifugal force to overcome the action of the tension spring and rotates relatively, so that the pawl meshes with the ratchet teeth of the fixed ratchet wheel, restricting the rotation of the pawl, thereby restricting the rotation of the linkage disk, and then restricting the movement of the air blocking plate; another In addition, two fixed grooves, two gear racks and two uniform components are provided. The two fixed grooves guide and limit the movement of the linkage plate and / or the gear rack to make its movement smooth. The resting directions of the ratchet teeth and pawls of the fixed ratchets of the two uniform components are opposite, so that one uniform component is used to ensure the uniformity of the outward stroke of the air blocking plate (the process in which the patient's exhalation acts on the air blocking plate, that is, the air blocking plate compresses the second spring), and the other uniform component ensures the uniformity of the return stroke of the air blocking plate (the process in which the patient inhales and the self-restoring force of the second spring causes the air blocking plate to move toward the side close to the air outlet end of the airway), thereby limiting the uniformity and stability of the entire breathing training process of exhalation and inhalation, and further improving the effect of breathing training.

[0020] 3. The present invention provides a breathing training and correction device for fracture surgery, in which an hourglass component is connected inside a shell to record the frequency and / or time of the patient's breathing training process, thereby ensuring the intensity of the patient's breathing training and improving the correction effect; wherein the hourglass component includes a windmill and cones arranged in pairs, and a fixed plate is provided with air guide holes that cooperate with the windmill. When the patient exhales into the shell, the gas acts on the windmill through the air guide holes, causing the windmill to rotate periodically, and the connection state between the cones arranged in pairs is controlled by a ball valve, and the cones contain a flowing medium (when starting training, the cones containing the flowing medium are arranged on the upper layer), and the operating shaft of the ball valve is fixedly connected to the rotating shaft of the windmill, and the windmill rotates When the ball valve rotates, the paired cones are periodically connected, so that the flowing medium in the upper cone flows into the lower cone periodically until all the flowing medium in the upper cone flows into the lower cone. The hourglass component completes a record. When used again, it is rotated 180 degrees and the cone containing the flowing medium is placed on the upper layer, and the hourglass timing and frequency can be recorded again. The hourglass component can record the intensity of a single breathing training of the patient to ensure the correction effect. The rotation of the windmill in the hourglass component and the flow of the flowing medium can be observed through the shell, which further improves the interest of the breathing training process. The flowing medium is selected from quicksand or quartz sand, both of which have good uniformity during the flow process.

[0021] 4. The present invention provides a breathing training correction device for fracture surgery, wherein a first spring having an elastic coefficient less than that of a second spring is connected between a linkage member and an air blocking plate. When the patient breathes lightly, the force of the gas can only overcome the force of the first spring to move the air blocking plate, thereby achieving training correction for light breathing. Moreover, the device has no requirement for uniformity and can be used for high-frequency training, thereby expanding the functionality of the entire breathing training correction device. The air blocking plate and the linkage member are also connected by two connecting rods and two sliders, and the two ends of the two connecting rods are rotatably connected to the slider and the air blocking plate, respectively, and the slider It is slidably connected with the linkage plate. When the air-blocking plate overcomes the action of the first spring and moves, the connecting rod rotates relative to the air-blocking plate and the slider, and the slider slides on the linkage plate, which can not only realize the functionality of breathing training, but also ensure the uniformity and stability of the air-blocking plate during the movement of the air-blocking plate relative to the linkage part; the two connecting rods and the two sliders are symmetrically arranged with the horizontal center plane of the first spring as the reference plane. The three (the first spring and the connecting rods on both sides) support and fix the air-blocking plate, so that the air-blocking plate is evenly stressed and stable, and the movement process is smooth when it is acted upon by gas.

[0022] 5. The present invention provides a breathing training correction device for post-fracture surgery. A truncated cone-shaped air nozzle is connected to the air outlet end of the airway, the air blocking plate is set to an arc shape, and the large end of the air nozzle faces the arc-shaped groove of the air blocking plate. In the process of the patient's exhaled gas acting on the air blocking plate through the airway and the air nozzle, the gas has good uniformity, a large area of ​​action on the air blocking plate, and high gas utilization efficiency, thereby improving the sensitivity of the entire breathing training correction device and ensuring its breathing training function; a rubber sealing sleeve is connected to the outer side of the shell, and the airway tube is slidingly sealed and penetrated in the rubber sealing sleeve to reduce the leakage of the inhaled gas, so that the air can act on the air blocking plate as much as possible, thereby improving the utilization rate of the gas and the accuracy of the entire breathing training correction device; the breathing mask is detachably connected to the airway, and after each use, or when different patients use it, it is convenient to disinfect and sterilize the breathing mask to avoid bacterial residue or cross infection between patients; an elastic strap is connected to the breathing mask, and when performing breathing training, the strap can be optionally put on the head to improve the convenience during breathing training and the stability of the breathing process.

[0033] An hourglass assembly is connected to the inner side of the shell 1, and the hourglass assembly includes a windmill 21 and two cones 22 arranged in pairs. The windmill 21 is rotatably connected to the shell 1, and the two cones 22 arranged in pairs are filled with a flowing medium. In the present embodiment, the flowing medium is quicksand, and a ball valve 23 for controlling the connection and / or closing thereof is connected between the two cones 22 arranged in pairs. The operating shaft of the ball valve 23 is fixedly connected to the rotating shaft of the windmill 21, and the two cones 22 arranged in pairs are symmetrically arranged with the horizontal center plane of the windmill 21 as the reference plane; the fixed plate 13 is provided with an air guide hole arranged in coordination with the windmill 21.

[0034] The specific implementation process is as follows:

[0035] When using the present breathing training correction device, firstly place one side of the cone 22 filled with quicksand on the upper layer, and place the idle cone 22 on the lower layer; then according to the actual needs of breathing training correction, rotate the airway 2, adjust the distance between the air nozzle 5 and the air blocking plate 9, and adjust the breathing resistance; finally, put the strap 4 on the head, align the mouth with the breathing mask 3, and start breathing training.

[0036] The airway tube 2 is rotated so that it moves along the axial direction of the internal threaded tube 24 under the action of the thread, so as to adjust the distance between the air outlet end and the air blocking plate 9, so that when the patient exhales gas of the same intensity, the air blocking plate 9 is subjected to different forces, and to ensure that the air blocking plate 9 can still achieve the same reciprocating motion when the distance between the air blocking plate 9 and the air outlet end of the airway tube 2 is different, the patient's exhalation intensity must be adjusted to adjust the breathing resistance, and the effect of adjusting the breathing training resistance is good, and the operation is convenient and fast;

[0037] The large end of the truncated cone-shaped air nozzle 5 faces the arc-shaped groove of the arc-shaped air blocking plate 9. In the process of the exhaled gas acting on the air blocking plate 9 through the airway tube 2 and the air nozzle 5, the gas has good uniformity, acts on the air blocking plate 9 The area is large, and the utilization efficiency of the gas is high, which improves the sensitivity of the entire breathing training correction device and ensures its breathing training function; the airway tube 2 is slidably sealed and penetrated into the rubber sealing sleeve 25 to reduce the leakage of the inhaled gas, so that it can act on the air blocking plate 9 as much as possible, improve the utilization rate of the gas, and improve the accuracy of the entire breathing training correction device; the breathing mask 3 is detachably connected to the airway tube 2. After each use, or when different patients use it, it is convenient to disinfect and sterilize the breathing mask 3 to avoid bacterial residue or cross infection between patients. An elastic bandage 4 is connected to the breathing mask 3. When performing breathing training, the bandage 4 can be optionally sleeved on the head to improve the convenience of the breathing training process and the stability of the breathing process;

[0038] When exhaling, the air blocking plate 9 is acted upon by the gas to overcome the force of the second spring 14 and moves toward the side away from the airway 2. When the patient inhales, the air blocking plate 9 is reset under the action of the second spring 14. By repeating this process, periodic breathing training can be performed. When the breathing is even, the linkage disk 17 rotates evenly and smoothly, and the tension spring 20 and the pawl 19 rotate with the rotation of the linkage disk 17. When the gear 16 rotates unevenly (suddenly accelerating or decelerating), the pawl 19 is acted upon by the centrifugal force to overcome the force of the tension spring 20 and rotate relatively, so that the pawl 19 engages with the ratchet teeth of the fixed ratchet wheel 18, restricting the rotation of the pawl 19, thereby restricting the rotation of the linkage disk 17, and further restricting the rotation of the gear 16. The movement of the air blocking plate 9; the two fixed groove bodies 7 guide and limit the movement of the linkage plate and / or the rack 15 to make it move smoothly. The ratchet teeth and pawls 19 of the fixed ratchet wheels 18 of the two uniform components are in opposite static directions, so that one uniform component is used to ensure the uniformity of the air blocking plate 9 in the outward stroke (the process in which the patient's exhalation acts on the air blocking plate 9, that is, the air blocking plate 9 compresses the second spring 14), and the other uniform component ensures the uniformity of the air blocking plate 9 in the return stroke (the process in which the self-restoring force of the second spring 14 causes the air blocking plate 9 to move toward the side close to the air outlet end of the airway 2 when the patient inhales), thereby limiting the uniformity and stability of the entire breathing training process of exhalation and inhalation, and further improving the effect of breathing training;

[0039] An hourglass component is provided in the shell 1 to record the frequency and / or time of the patient's breathing training process, thereby ensuring the intensity of the patient's breathing training and improving the correction effect; when exhaling into the shell 1, the gas acts on the windmill 21 through the air guide hole, causing the windmill 21 to rotate periodically, driving the ball valve 23 to rotate accordingly, and periodically connecting the paired cones 22, so that the quicksand in the upper cone 22 periodically flows into the lower cone 22, until the flowing medium in the upper cone 22 flows into the lower cone 22, and the hourglass component completes a record. When used again, it is rotated 180 degrees, and the cone 22 containing the flowing medium is placed on the upper layer, and the hourglass timing and frequency can be recorded again; the hourglass component can record the intensity of a single breathing training of the patient to ensure the correction effect;

[0040] A first spring 12 with an elastic coefficient less than that of the second spring 14 is connected between the linkage 8 and the air blocking plate 9. When the patient breathes lightly, the force of the gas can only overcome the force of the first spring 12 to move the air blocking plate 9, thereby realizing the training correction of light breathing. Moreover, it has no requirement for uniformity and can be used for high-frequency training, thereby expanding the functionality of the entire breathing training correction device. The air blocking plate 9 and the linkage 8 are also connected by two connecting rods 11 and two sliding blocks 10. When the air blocking plate 9 overcomes the action of the first spring 12 and moves, the connecting rod 11 rotates relative to the air blocking plate 9 and the sliding block 10, and the sliding block 10 slides on the linkage plate, thereby realizing the functionality of breathing training and ensuring the uniformity and stability of the movement of the air blocking plate 9.

[0041] The shell 1 is made of transparent material, which is convenient for observing the distance between the air outlet end of the air guide tube 2 and the air blocking plate 9, and convenient for observing the movement of the air blocking plate 9, the linkage 8, the rack 15, the gear 16, etc. during the breathing training process, thereby increasing the interest of the breathing training. The rotation of the windmill 21 in the hourglass assembly and the flow of the flowing medium can be observed through the shell 1, thereby increasing the interest of the breathing training process.

[0042] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical scheme or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical scheme of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
