Description

Technical Field

[0001] The present invention relates to the technical field of lung exercise, in particular to a lung function exercise device for cardiothoracic surgery. Background Art

[0002] In the field of cardiothoracic surgery, the recovery of a patient's lung function after surgery is crucial. Traditional pulmonary function training methods have many limitations. For example, training equipment often only provides single exhalation or inhalation training functions, failing to comprehensively and systematically train the patient's respiratory system. Furthermore, the limited resistance adjustment range of traditional devices makes it difficult to meet the individual needs of different patients during rehabilitation, resulting in poor training results. Furthermore, most traditional devices lack real-time monitoring capabilities, unable to provide medical staff with accurate data on the patient's lung function recovery, hindering timely adjustment of treatment plans. More seriously, some devices have unreasonable gas flow path designs, posing the risk of gas backflow, which not only affects the effectiveness of the training but also may cause complications such as infection, posing additional risks to the patient's recovery. Given these shortcomings of traditional pulmonary function training equipment, there is an urgent need for a pulmonary function training device that can provide comprehensive and personalized training support, possesses real-time monitoring capabilities, and is rationally designed to better serve the postoperative rehabilitation of cardiothoracic surgery patients.

[0050] Example 1:

[0051] like Figures 1 to 10 As shown, this embodiment provides a pulmonary function training device for thoracic and cardiovascular surgery, comprising: a mounting housing 1, a connecting tube 2 provided on one side of the mounting housing 1, a wearing mask 3 connected to one end of the connecting tube 2 away from the mounting housing 1, an exhalation training unit 4 provided at one end of the connecting tube 2, an inhalation training unit 5 provided at the other end of the connecting tube 2, and a one-way adjustment plate 6 provided on the inner side of the connecting tube 2;

[0052] The exhalation training unit 4 includes an exhalation resistance adjustment component, a manual adjustment component and an exhalation test component, and the inhalation training unit 5 includes an inhalation resistance adjustment component and an inhalation test component.

[0053] In this embodiment, the housing 1, the connecting tube 2, the wearing mask 3, the exhalation training unit 4, the inhalation training unit 5 and the one-way adjustment plate 6 are installed to form a pulmonary function training device for cardiothoracic surgery involved in this application.

[0054] In some embodiments, the exhalation resistance adjustment component includes an exhalation air transmission tube 41 arranged at one end of the connecting tube 2, and the inner side of the exhalation air transmission tube 41 is connected to a first fixed plate 42, and a first pull rod 43 is slidably connected to the first fixed plate 42, and an exhalation exercise spring 44 is sleeved on the outer side of the first pull rod 43, and one end of the first pull rod 43 is connected to an exhalation push plate 45, and at the same time, the side of the exhalation push plate 45 near the first pull rod 43 of the exhalation exercise spring 44 is connected to an air outlet ring 46, and the side of the exhalation air transmission tube 41 near the exhalation push plate 45 is provided with an air outlet hole 47.

[0055] It should be noted that corresponding holes are provided on the first pull rod 43 and the exhalation air transmission tube 41. By pulling the first pull rod 43, the two holes can be aligned and fixed by a pin, so that the air outlet baffle ring 46 no longer blocks the air outlet hole 47. The exhalation push plate 45 and the air outlet baffle ring 46 fit and slide on the inner side of the exhalation air transmission tube 41. The two ends of the exhalation training spring 44 are respectively fixedly connected to one side of the exhalation push plate 45 and one side of the first fixed plate 42. The exhalation air transmission tube 41 is arranged on the inner side of the connecting tube 2.

[0056] In this embodiment, the exhalation gas transmission pipe 41 is a cylindrical pipe made of stainless steel, which has good corrosion resistance and air tightness, ensuring the stability and reliability of the gas transmission process. The first fixed plate 42 is made of high-strength aluminum alloy, which can not only ensure structural strength but also reduce the overall weight.

[0057] In some embodiments, the manual adjustment component includes a connecting shell 48 arranged on the exhalation air transmission tube 41, and the inner side of the connecting shell 48 is slidably connected to a sliding block 49, and the upper middle position of the sliding block 49 is connected to a connecting slide rod 410, and the upper end of the connecting slide rod 410 is slidably connected to a block rod 411.

[0058] Specifically, the blocking rod 411 is slidably connected to the extension plate provided on the connecting pipe 2, and is slidably connected to the connecting slide rod 410 through the extension plate. A plurality of groups of spaces are provided on the inner side of the connecting shell 48 for exhaust and air intake. The number of connecting slide rods 410 and sliding blocks 49 is equal to the number of spaces and is arranged one-to-one. The connecting slide rod 410 is slidably connected to the connecting pipe 2.

[0059] As a preferred embodiment, the blown gas enters the exhalation test tube 413 through the connecting shell 48 and the exhalation connecting tube 4122, pressing the exhalation test float 415 downward, and the exhalation test spring 414 generates resistance to the exhalation test float 415, indirectly generating resistance for the exerciser to blow. By observing the position change and scale line of the exhalation test float 415, the strength and volume of the blown gas can be judged, providing intuitive data support for the exercise effect.

[0060] Example 2:

[0061] In some embodiments, the exhalation test assembly includes an exhalation connecting tube 412 arranged on one side of the connecting shell 48, and the end of the exhalation connecting tube 412 away from the connecting shell 48 is connected to the exhalation test cylinder 413, and an exhalation test spring 414 is arranged at the lower inner side of the exhalation test cylinder 413, and the upper end of the exhalation test spring 414 away from the exhalation test cylinder 413 is connected to the exhalation test float 415.

[0062] It should be noted that the exhalation test cylinder 413 is fixedly arranged on the outside of the mounting shell 1, the exhalation connecting tube 412 is arranged on the upper side of the exhalation test cylinder 413, and the exhalation test float 415 slides on the inner side of the exhalation test cylinder 413. The outside of the exhalation test cylinder 413 is provided with a scale line (not shown), and the exhalation connecting tube 412 is arranged on the upper side of the exhalation test float 415.

[0063] In this embodiment, when the exerciser blows air, the gas pushes the exhalation push plate 45 to slide in the exhalation air transmission tube 41, and the air outlet baffle ring 46 slides accordingly and gradually separates from the air outlet hole 47, and the gas then flows into the connecting shell 48. The greater the degree of separation between the air outlet baffle ring 46 and the air outlet hole 47, the smaller the resistance generated, thereby adjusting the blowing resistance, so that the exerciser can adjust the blowing force according to his own situation and improve the exercise effect.

[0064] In some embodiments, the inhalation resistance adjustment component includes an inhalation air transfer tube 51 arranged at the end of the connecting tube 2 away from the expiratory air transfer tube 41, the inner side of the inhalation air transfer tube 51 is connected to a second fixed disk 52, the middle position of the second fixed disk 52 is connected to a second pull rod 53, one end of the second pull rod 53 is connected to an inhalation pull plate 511, the outer side of the second pull rod 53 is provided with an inhalation exercise spring 54, the side of the inhalation pull plate 511 close to the second pull rod 53 is provided with an air intake ring 55, and the lower side of the inhalation air transfer tube 51 close to the inhalation pull plate 511 is provided with an air intake hole 56.

[0065] It should be noted that the intake air transmission tube 51 is fixedly arranged at one end of the connecting tube 2 away from the exhalation air transmission tube 41, the second pull rod 53 is slidably connected to the second fixed plate 52, and the two ends of the intake exercise spring 54 are respectively fixedly connected to one side of the intake pull plate 511 and one side of the second fixed plate 52, the intake pull plate 511 and the intake exercise spring 54 slide in contact with the inner side of the intake air transmission tube 51, and the intake air transmission tube 51 is arranged on the inner side of the mounting shell 1.

[0066] Specifically, two groups of manual adjustment components are provided, which are respectively arranged on the upper side of the air outlet 47 and the lower side of the air inlet 56.

[0067] In this arrangement, by pulling the blocking rod 411, the blocking rod 411 is separated from the connecting slide rod 410, and pressing the connecting slide rod 410 downward, the sliding block 49 is driven to move, thereby blocking or opening the corresponding space, and then adjusting the gas flow path, realizing manual adjustment of the exhalation resistance to meet different exercise needs.

[0068] Example 3:

[0069] In some embodiments, the air intake test assembly includes an air intake connecting pipe 57 arranged on one side of the connecting shell 48, one end of the air intake connecting pipe 57 is connected to an air intake test cylinder 58, an air intake test spring 59 is arranged on the upper inner side of the air intake test cylinder 58, and the lower end of the air intake test spring 59 away from the air intake test cylinder 58 is connected to an air intake test float 510.

[0070] Specifically, the air intake connecting pipe 57 is arranged on the lower side of the air intake test spring 59, the air intake connecting pipe 57 is arranged on the lower side of the air intake test float 510, the air intake test cylinder 58 is fixedly arranged on the mounting shell 1, and the air intake test float 510 slides on the inner side of the air intake test cylinder 58.

[0071] Among them, the blown gas enters the exhalation test cylinder 413 through the connecting shell 48 and the exhalation connecting tube 4122, pressing the exhalation test float 415 downward, and the exhalation test spring 414 generates resistance to the exhalation test float 415, indirectly generating resistance for the exerciser to blow air. By observing the position change and scale line of the exhalation test float 415, the strength and volume of the blown gas can be judged, providing intuitive data support for the exercise effect.

[0072] In some embodiments, the one-way adjustment plate 6 includes a baffle 61 that slides on the inner side of the connecting tube 2, and a first connecting plate 62 is connected to one side of the baffle 61, and the first connecting plate 62 is connected to the second connecting plate 64 through a rotating shaft, and a torsion spring 63 is provided on the outer side of the rotating shaft. The one-way adjustment plate 6 is provided in two groups and is symmetrically arranged on the inner side of the connecting tube 2.

[0073] It should be noted that there are two groups of baffles 61, and the baffles 61 have the same flipping direction in the connecting pipe 2, and are only flipped in the hole provided on the inner side of the connecting pipe 2. At the same time, one side of the baffle 61 is attached to the edge of the inner hole of the connecting pipe 2.

[0074] In this embodiment, when the exerciser blows air, the gas pushes another set of one-way adjustment plates 6, causing a set of baffles 61 to open and flip, and the other set of one-way adjustment plates 6 presses against the inner side of the connecting pipe 2, and the gas enters the exhalation exercise unit 4 through the opened baffles 61; when the exerciser inhales, the gas flows to the connecting pipe 2 through the inhalation exercise unit 5, and the one-way adjustment plates 6 prevent the gas from flowing in the opposite direction, thereby realizing one-way circulation of the gas and ensuring the smooth progress of the exercise process.

[0075] It should be noted that the exhalation test tube 413 and the inhalation test tube 58 are made of transparent materials.

[0076] During use, the exerciser first puts on the mask 3 and blows air into the connecting tube 2. The air passes through the connecting tube 2 and pushes the other set of one-way adjustment plates 6, driving the set of baffles 61 to open and flip. At the same time, the other set of one-way adjustment plates 6 does not open but presses against the inner side of the connecting tube 2 due to the air being injected. The air enters the exhalation exercise unit 4 through the set of baffles 61.

[0077] The gas pushes the exhalation push plate 45 to slide inside the exhalation air transmission tube 41. At the same time, the air outlet baffle ring 46 slides inside the exhalation air transmission tube 41, so that the air outlet baffle ring 46 and the air outlet hole 47 are gradually separated, so that the gas can flow into the connecting shell 48. The air outlet baffle ring 46 and the air outlet hole 47 are gradually separated, which will generate resistance when the exerciser blows air. The greater the separation, the smaller the resistance.

[0078] The blown air passes through the connecting shell 48 and the exhalation connecting tube 412 and enters the exhalation test cylinder 413, and presses the exhalation test float 415 downward. The exhalation test spring 414 generates a certain resistance to the exhalation test float 415, and indirectly generates resistance to the exerciser's blowing. The blown air drives the exhalation test float 415 to move downward, and the scale lines provided on the exhalation test spring 414 are used to judge the force and volume of the blown air.

[0079] When the air blow measurement is finished, the gas is discharged by opening the piston (not shown) on the upper side of the air exhalation test spring 414;

[0080] During inhalation exercise, the piston (not shown) provided on the lower side of the inhalation test cylinder 58 is opened, allowing air to flow through the inhalation test cylinder 58 and into the connecting pipe 2. The piston is then closed, and the exerciser inhales air into the connecting pipe 2. The suction force generated drives the inhalation pull plate 511 to move within the inhalation air transmission pipe 51, driving the air intake baffle ring 55 to move, which gradually blocks the air intake hole 56. This increases the resistance when the exerciser inhales, thereby achieving the purpose of the exercise.

[0081] Inhalation reduces the air inside the inhalation test cylinder 58, generating suction on the inhalation test float 510, driving the inhalation test float 510 to move downward. At the same time, the inhalation test spring 59 generates resistance to the inhalation test float 510, indirectly generating resistance for the exerciser when inhaling. The scale lines on the inhalation test cylinder 58 are used to judge the suction force and inhalation capacity of the inhalation.

[0082] When the exerciser wants to perform fixed resistance exercise, by pulling the first pull rod 43, the first pull rod 43 and the hole on the exhalation air transmission tube 41 are aligned and fixed by a pin, and by pulling the blocking rod 411, the blocking rod 411 is separated from the connecting slide rod 410, and the connecting slide rod 410 is pressed downward to make the sliding block 49 block the air outlet 47. The exerciser can set the number of times the connecting slide rod 410 is pressed downward according to needs to adjust the number of air outlet holes 47, so as to adjust the air intake resistance into the exhalation test cylinder 413 and the air inhalation resistance from the inhalation test cylinder 58. When the number of air outlet holes 47 is adjusted, the blocking rod 411 is restored to its original position and positioned by the blocking rod 411 passing through the connecting slide rod 410 that has not descended or ascended. At the same time, the blocking rod 411 will resist the descending or ascending blocking rod 411 to prevent the blocking rod 411 from ascending or descending.

[0083] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
