Description

Technical Field

[0001] The present invention relates to the technical field of medical care, and particularly to a lung function exercise device for clinical nursing in cardiothoracic surgery. Background Art

[0002] With the continuous progress of medical technology, the accuracy and safety of cardiothoracic surgery have been significantly improved. However, the postoperative rehabilitation process still faces many challenges, among which lung function recovery is a crucial part. Therefore, lung function exercises are also carried out before or after some surgeries. Performing lung function exercises before surgery, such as using a respiratory function trainer, can significantly improve the patient's pulmonary ventilation function, improve blood gas analysis indicators, thereby enhancing surgical tolerance and reducing surgical risks. Postoperative lung function exercises play an important role in promoting lung re-expansion and reducing air leakage in patients. Through exercise, patients can more effectively discharge the accumulated blood and gas in the chest cavity and accelerate the rehabilitation process.

[0003] Some devices in the prior art are usually made of an integrated structure with a transparent material, and corresponding vital capacity scales are marked on their outer shells. When the patient exhales into it through the intake pipe, the gas drives the movement of the internal moving parts (such as small balls, etc.) to the corresponding scale lines, facilitating doctors to directly observe the patient's current lung function situation, so as to help doctors make normal decisions. Since there is gaseous water in the exhaled gas of people, when the gas flows through the above-mentioned device, water droplets will gradually form on the inner wall of the device, interfering with the staff's line of sight to observe the scale line. Especially when the environmental temperature is relatively low (such as in winter), when the inner wall of the device comes into contact with the exhaled gas of the patient passing through, due to the large temperature difference between the gas temperature and the inner wall, a layer of water mist will quickly form on the inner wall, further interfering with the observation of the movement position of the internal moving parts.

[0004] Therefore, the present invention proposes a lung function exercise device for clinical nursing in cardiothoracic surgery to solve the above problems. Summary of the Invention

[0005] To solve the above problems, the present invention provides a lung function exercise device for clinical nursing in cardiothoracic surgery, which can timely clean the water stains on the inner wall of the device and reduce the interference of the water stains on the observation of the movement of the internal structure.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A lung function exercise device for clinical nursing in cardiothoracic surgery, including a first outer shell and a second outer shell, the first outer shell and the second outer shell are detachably connected, an air inlet pipe and an air outlet are arranged on the surface of the first outer shell, the internal cavity formed by the combination of the first outer shell and the second outer shell is a circular cavity, a rotating rod is arranged inside the first outer shell, both ends of the rotating rod are rotatably connected to the inner walls of the first outer shell and the second outer shell respectively, a number of rectangular blades are circularly arranged on the rotating rod, sponge layers are arranged along the circumferences of the rectangular blades, and the sponge layers are in contact with the inner walls of the first outer shell and the second outer shell respectively.

[0007] Principle of the basic solution: Using the gas exhaled by the patient as the driving force to drive the rectangular blades to rotate, which can exercise the patient's lung function. At the same time, during the rotation of the blades, the sponge layers on them are used to adsorb and clean the water stains on the inner walls of the first outer shell and the second outer shell.

[0008] The above solution has the following beneficial effects:

[0009] 1. Compared with the prior art, this solution drives the blade to rotate through the patient's own breathing, which not only enhances the fun and participation of the exercise, but also helps to significantly improve the recovery effect of the patient's lung function and accelerate the rehabilitation process. At the same time, by using the rotation of the blades (i.e., the gas exhaled by the patient during training), the problem of water stains on the inner wall of the device interfering with observation is cleverly solved through the design of the sponge layer. During the patient's exhalation process, the sponge layer can adsorb and clean the water stains in real time, ensuring that the doctor can clearly and accurately observe the movement state of the internal structure, so as to make more accurate medical decisions.

[0010] 2. In this solution, the detachable connection design of the first outer shell and the second outer shell makes the cleaning and maintenance of the device simpler and more convenient. Medical staff can easily disassemble the outer shell to clean or replace the internal components, ensuring the continuous and efficient operation of the device.

[0011] Further, a placement table is fixedly connected to the side of the first outer shell away from the second outer shell. An arc-shaped through groove is opened along the length direction of the top of the placement table. One end of the rotating rod passes through the first outer shell and extends into the arc-shaped through groove, and the part of the rotating rod located in the arc-shaped through groove is a polygonal structure. A number of configuration discs are placed in the arc-shaped groove, and the configuration discs are all slidably connected to the rotating rod.

[0012] Beneficial effect: According to the actual situation of different patients, place an appropriate number of configuration discs into the arc-shaped through groove, and use their weight and the friction with the arc-shaped through groove to adjust the resistance when the rotating rod rotates, thereby adjusting the difficulty of the patient's lung function exercise and improving the adaptability of the device.

[0013] Further, a limiting cover is hinged to the end of the placement table away from the first outer shell.

[0014] Beneficial effects: Prevent the configuration disc from falling off the arc-shaped through groove during rotation, which affects the exercise effect. At the same time, through its hinge design, it is also convenient for placing and taking the configuration disc to quickly adjust the exercise difficulty.

[0015] Furthermore, a disinfection box for disinfecting the inside of the first housing and the second housing is fixedly connected to one end of the second housing away from the first housing.

[0016] Beneficial effects: The design of the disinfection box enables the device to be thoroughly disinfected during each use or regular maintenance, effectively killing potential bacteria and viruses, and ensuring the safety and health of patients.

[0017] Furthermore, a push rod is rotatably connected inside the disinfection box. One end of the rotating rod extends into the disinfection box through the second housing. The rotating rod passes through the push rod and is slidably matched with it, and the part of the rotating rod located inside the disinfection box is polygonal; a storage bin for storing disinfectant is arranged inside the disinfection box, and a sliding channel communicating with it is arranged above the storage bin; a piston slidably matched with the sliding channel is arranged inside the disinfection box. The top of the piston is fixedly connected with a connecting rod, the top of the connecting rod is fixedly connected with a pressure-receiving cap, a spring sleeved on the connecting rod is fixedly connected to the bottom of the pressure-receiving cap, the bottom end of the spring is fixedly connected to the disinfection box, and a liquid spraying port communicating with a circular cavity is opened on the inner wall of the storage bin; the pressure-receiving cap is located within the movement track of the push rod.

[0018] Beneficial effects: When the rotating rod rotates, its polygonal structure part will push the push rod to rotate inside the disinfection box. When the push rod rotates to the position of the pressure-receiving cap, it will push the pressure-receiving cap downward, thereby driving the piston to slide in the sliding channel. The sliding of the piston sprays the disinfectant in the storage bin into the circular cavity through the liquid spraying port to further disinfect the inside of the first housing and the second housing, effectively improving the hygiene and safety performance of the device.

[0019] Furthermore, the pressure-receiving cap has a dome structure.

[0020] Beneficial effects: The pressure-receiving cap with a dome structure enables the pressure-receiving cap and the push rod to be in contact with two arc-shaped surfaces, so that the push rod can more smoothly push the pressure-receiving cap downward during rotation, thus ensuring the stable execution of the disinfectant spraying function. This helps to avoid problems such as jamming, failure, or uneven spraying caused by uneven force, and improves the reliability and user experience of the device.

[0021] Furthermore, the bottom of the storage bin has a round-bottom structure.

[0022] Beneficial effects: The bottom of the storage bin is designed as a round-bottom structure. This round-bottom structure can not only increase the volume utilization rate of the storage bin, enabling the disinfectant to be more fully filled in the storage bin and reducing waste; at the same time, the round-bottom structure can also make the disinfectant more evenly distributed in the storage bin, which is beneficial for the piston to output the disinfectant more smoothly and continuously when pushing it, thereby improving the spraying uniformity and effect.

[0023] Furthermore, a number of rubber sheets are arranged inside the liquid spraying port.

[0024] Beneficial effects: These rubber sheets can flexibly open and close the liquid spraying port to achieve precise control of the disinfectant flow rate. When the piston pushes the disinfectant towards the liquid spraying port, the rubber sheets will automatically adjust their opening degree according to the pressure and flow rate of the disinfectant, ensuring that the disinfectant can be evenly and stably sprayed into the disinfection box. At the same time, the elastic design of the rubber sheets can also effectively prevent the leakage and waste of the disinfectant during the spraying process.

[0025] Furthermore, a handle is arranged at the top of the first outer shell.

[0026] Beneficial effects: By arranging the handle, medical staff can easily lift or carry the device. Whether moving within the ward or transporting between different departments, it can greatly reduce the work burden and improve work efficiency.

[0027] Furthermore, a base is arranged at the bottom of the first outer shell.

[0028] Beneficial effects: By arranging the base, the device can be kept stable during placement and use, preventing it from sliding or tipping over. This helps to ensure the safety of medical staff during operation and avoid accidental events caused by the instability of the device.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0040] The following will be further described in detail through specific implementation manners:

[0041] Embodiment 1:

[0042] As shown in the attached Figure 1 、Figure 2 , Figure 3 and Figure 6 as shown: A lung function exercise device for cardiothoracic clinical nursing, including a first outer shell 2 and a second outer shell 4. The first outer shell 2 and the second outer shell 4 are detachably connected. In order to ensure the tightness of the connection between the two, a sealing ring can be provided at the connection between the two. At the same time, the first outer shell 2 and the second outer shell 4 are preferably made of transparent plastic material to facilitate observing the movement of internal components. An air inlet pipe 3 and an air outlet 8 are provided on the surface of the first outer shell 2. The internal cavity formed by the combination of the first outer shell 2 and the second outer shell 4 is a circular cavity. A rotating rod 12 is provided inside the first outer shell 2. The material of the rotating rod 12 is preferably lightweight plastic to ensure that the patient can drive the rotating rod 12 by exhaling in the initial state. Both ends of the rotating rod 12 are rotatably connected to the inner walls of the first outer shell 2 and the second outer shell 4 respectively. A number of rectangular blades 11 are circularly arrayed on the rotating rod 12. Sponge layers 10 are provided along the circumferences of the rectangular blades 11. The sponge layers 10 are all in contact with the inner walls of the first outer shell 2 and the second outer shell 4. The sponge layers 10 are used to reduce the gap between the edges of the rectangular blades 11 and the inner wall of the circular cavity, so as to ensure that most of the kinetic energy of the gas exhaled by the patient acts on the rectangular blades 11 to achieve the basic lung function exercise effect. When the patient inflates the circular cavity through the air inlet pipe 3, the exhaled gas acts on the surface of the rectangular blades 11, so that the rectangular blades 11 and the rotating rod 12 rotate together. During the rotation process, the sponge layers 10 at the edges of the rectangular blades 11 are always in contact with the inner wall of the circular cavity, that is, the sponge layers 10 will synchronously adsorb and clean the water stains on the inner wall during the rotation of the rectangular blades 11, so as to facilitate the medical staff to clearly observe the rotation of the internal rectangular blades 11 and reduce the situation of water mist attachment on the inner wall due to temperature difference, so as to facilitate the medical staff to adjust the training difficulty according to the actual situation of the patient.

[0043] For different stages of different patients, the required exercise difficulty is different. Therefore, a placement table 6 is screw-connected to the side of the first housing 2 away from the second housing 4. An arc-shaped through groove is formed in the top of the placement table 6 along its length direction. One end of the rotating rod 12 passes through the first housing 2 and extends into the arc-shaped through groove. The part of the rotating rod 12 located in the arc-shaped through groove is of a polygonal structure. A number of configuration discs 5 are placed in the arc-shaped groove. The configuration discs 5 are all slidably connected to the rotating rod 12. At the same time, the configuration discs 5 placed in the arc-shaped through groove are in contact with the inner wall of the arc-shaped through groove. Thus, by placing or taking the configuration discs 5 on the arc-shaped through groove of the placement table 6, using their gravity and the friction force with the inner wall of the arc-shaped through groove, the resistance when the rotating rod 12 rotates is increased, that is, the resistance during the lung function exercise of the patient is increased, so as to realize the controllable adjustment of the training difficulty according to the actual situation of different patients, and enhance the flexibility and practicability of the device. For the configuration discs 5, models with different weights can be set, and corresponding weights and corresponding resistances are marked on their surfaces, so that it is convenient for patients or medical staff to more intuitively see the current training intensity, and it can also avoid the situation where the water mist in some existing devices affects the observation of the scale line. At the same time, a limit cover 7 is hinged to the end of the placement table 6 away from the first housing 2 to prevent the configuration discs 5 from falling off the arc-shaped through groove during the rotation process, affecting the exercise effect. At the same time, due to its hinged design, it is also convenient for placing and taking the configuration discs 5 to quickly adjust the exercise difficulty.

[0044] Embodiment 2:

[0045] The difference from Embodiment 1 is that, as Figure 4 and Figure 5As shown, a disinfection box 9 for disinfecting the interiors of the first housing 2 and the second housing 4 is integrally formed at one end of the second housing 4 away from the first housing 2. A push rod 13 is rotatably connected inside the disinfection box 9. One end of a rotating rod 12 extends through the second housing 4 into the disinfection box 9. The rotating rod 12 passes through the push rod 13 and is slidably engaged with it, and the part of the rotating rod 12 located inside the disinfection box 9 is polygonal. Inside the disinfection box 9, a storage bin for storing disinfectant liquid is provided. The bottom of the storage bin is of a round-bottom structure, which can enable the disinfectant liquid in the storage bin to always gather at the bottom of the storage bin due to its own gravity, increasing the volume utilization rate of the storage bin, making the disinfectant liquid fill the storage bin more fully, reducing waste. At the same time, the round-bottom structure can also make the disinfectant liquid distribute more evenly in the storage bin, which is beneficial for the piston 17 to output more smoothly and continuously when pushing the disinfectant liquid, thereby improving the uniformity and effect of spraying. A sliding channel communicating with it is provided above the storage bin. A piston 17 slidably engaged with the sliding channel is provided inside the disinfection box 9. A connecting rod 16 is fixedly connected to the top of the piston 17, and a pressure-receiving cap 14 is fixedly connected to the top of the connecting rod 16. At the same time, in order to ensure that the push rod 13 can smoothly cross the pressure-receiving cap 14, the pressure-receiving cap 14 is set as a round-dome structure, so that when the pressure-receiving cap 14 and the push rod 13 contact, it is the contact of two arc surfaces, making the push rod 13 more smoothly push the pressure-receiving cap 14 downward during the rotation process, thereby ensuring the stable execution of the disinfectant liquid spraying function and helping to avoid problems such as jamming, failure or uneven spraying caused by uneven force. A spring 15 sleeved on the connecting rod 16 is fixedly connected to the bottom of the pressure-receiving cap 14, and the bottom end of the spring 15 is fixedly connected to the disinfection box 9. A liquid spraying port 18 communicating with a circular cavity is opened on the inner wall of the storage bin. At the same time, in order to ensure that the disinfectant liquid in the storage bin can be stably sprayed according to the movement of the piston 17, a number of rubber sheets are provided inside the liquid spraying port 18, which can not only make the liquid in the storage bin sprayed evenly and stably inside the disinfection box 9 when the piston 17 squeezes the liquid in the storage bin, but also, during the upward movement of the piston 17, due to the elasticity of the rubber sheets, it can ensure the flow of air into the storage bin to ensure the smooth movement of the piston 17, and at the same time can effectively prevent the leakage and waste problems of the disinfectant liquid during the spraying process. The pressure-receiving cap 14 is located within the movement track of the push rod 13.

[0046] The specific implementation process is as follows: When the rotating rod 12 rotates, its polygonal structure part will push the push rod 13 to rotate inside the disinfection box 9. When the push rod 13 rotates to the position of the pressure-receiving cap 14, it will push the pressure-receiving cap 14 downward, thereby driving the piston 17 to slide downward in the sliding channel, so as to squeeze the air and liquid in the storage bin, making the pressure at the liquid spraying port 18 gradually increase. When the pressure is sufficient to cause the rubber sheet in the liquid spraying port 18 to undergo elastic deformation, the liquid medicine in the storage bin is sprayed out. And as the rectangular blade 11 rotates, it is evenly smeared on the inner wall of the circular cavity to achieve comprehensive disinfection, thereby ensuring the safety of the device during repeated use in a short period of time. However, at the same time, for such a medical device, after a relatively long period of time, it is also necessary to disassemble and clean or replace components. For example, the sponge layer 10 in this device also needs to disassemble the first outer shell 2 and the second outer shell 4 for replacement or cleaning after being used for a period of time. At the same time, the spring 15 is used to provide a reset force for the pressure-receiving cap 14 to realize the reciprocating motion of the piston 17, that is, to realize continuous disinfection treatment.

[0047] Embodiment 3:

[0048] The difference from Embodiment 2 is that a handle is integrally formed on the top of the first outer shell 2, enabling medical staff to easily lift or carry the device. Whether moving in the ward or transporting between different departments, it can greatly reduce the work burden and improve work efficiency. A base 1 is integrally formed at the bottom of the first outer shell 2, enabling the device to remain stable during placement and use, preventing it from sliding or tipping over. This helps to ensure the safety of medical staff during the operation process and avoid accidental events caused by the instability of the device.

[0049] Embodiment 4:

[0050] The difference from Embodiment 3 is that, as Figure 2As shown in the figure, a rotational speed sensor is provided on the rotating rod 12, a pressure sensor is provided on the part of the rotating rod located in the arc-shaped through groove, a controller is provided on the surface of the disinfection box 9, and both the pressure sensor and the rotational speed sensor are electrically connected to the controller. At the same time, the controller is preferably a Raspberry Pi all-in-one machine, which can not only obtain the signals of the rotational speed sensor and the pressure sensor, analyze and process them, but also display the processed data on the controller for medical staff to observe, so as to adjust the number of configuration discs 5 according to the actual situation. Through the rotational speed sensor, the speed at which the rotating rod 12 is driven to rotate during the patient's exhalation process can be accurately obtained, and through the pressure sensor, the pressure borne by the rotating rod 12 can be obtained in real time, and then the current exercise difficulty can be deduced, so as to jointly reflect the vital capacity of the patient and the strength of the respiratory muscles. According to the data on the screen, medical staff can judge the current pulmonary function status of the patient and adjust the number of configuration discs 5 accordingly to change the exercise difficulty. If it is necessary to increase the difficulty, more configuration discs 5 are added to the arc-shaped through groove; if it is necessary to reduce the difficulty, some configuration discs 5 are taken out.

[0051] Obviously, the above embodiments are only examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
