Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field more specifically, relate to a kind of inhalation flow rate measuring instrument with training function. BACKGROUND

[0002] Respiratory disease patients need to inhale mist or powder medicament in treatment, and the diameter of drug particles in medicament and inhalation speed are the most important factors affecting the deposition rate of drug. Therefore, different inhalation speed is required for different inhalation preparations. The inhalation flow rate required by the commonly used mist medicament on the market is generally >30L / min, while the inhalation flow rate required by the powder medicament is relatively high, and the inhalation flow rate is generally required to be >60L / min. In actual treatment, there is a situation that the inhalation flow rate of patients is insufficient and affects the efficacy of medicament.

[0003] In the prior art, the inhalation flow rate of patients can be exercised by the inhalation training device, which is convenient for treatment. However, the existing inhalation training device can only perform inhalation operation, cannot directly switch between inhalation and exhalation, reduces the continuity and integrity of training, is not convenient for adjusting the inhalation resistance according to the specific condition of patients, has poor training effect, and cannot detect the inhalation flow rate value of patients during training, so that the training results cannot be intuitively reflected. UTILITY MODEL CONTENT

[0004] The utility model discloses to overcome the defect that the existing inhalation training device in the prior art cannot detect the inhalation flow rate value of patients, and provides an inhalation flow rate measuring instrument with training function, which can measure the inhalation flow rate value of patients during inhalation training, and is convenient for observing training results.

[0005] To solve the above technical problems, the utility model adopts the technical scheme of: an inhalation flow rate measuring instrument with training function, comprising: a cylindrical member, a sealing member and a positioning member slidably connected with the cylindrical member respectively, a first elastic member connected with the sealing member and the cylindrical member at both ends respectively, and a one-way valve assembly, the sealing member and the positioning member are located in the cylindrical member, the one-way valve assembly is communicated with the cylindrical member and unidirectional air outlet, the cylindrical member is provided with a first end portion for inhalation or exhalation and a second end portion for communicating external air pressure, the positioning member and the one-way valve assembly are located on the side of the sealing member close to the first end portion, the cylindrical member is of transparent material, and scale lines are arranged on the outer side surface.

[0006] In use, the cylindrical component must maintain a horizontal axis. A sealing element is located inside the cylindrical component and seals against its inner wall, thus isolating gas from both sides. The one-way valve assembly is designed to allow only air to exit and not enter. When the user's mouth is fully in contact with the first end and inhales, the gas on the side of the sealing element near the first end is drawn away, creating a negative pressure. The side of the sealing element near the second end is connected to the outside atmosphere. Therefore, the sealing element moves towards the first end under the negative pressure, simultaneously moving the positioning element. At this time, the first elastic element is also compressed or stretched. Simultaneously, the positioning element slides against the cylindrical component and abuts against the sealing element. The cylindrical component is made of transparent material. When the user stops inhaling, the first elastic element... The device repositions the sealing element, while the positioning element remains inside the cylindrical component. The scale lines on the side of the cylindrical component correspond to different inhalation airflow rates. The user's inhalation airflow rate can be measured by observing the scale lines on the positioning element. During continuous breathing training, the user inhales and then exhales. The exhaled air flows out through the one-way valve assembly. Upon inhalation again, the one-way valve assembly closes again, creating negative pressure inside the cylindrical component. During this process, the user may move the positioning element while exhaling, causing it to move dynamically back and forth. The user can judge the effectiveness of the breathing training by observing the maximum value of the positioning element, i.e., the position closest to the first end. Regardless of whether the positioning element is moved during breathing training, the training effect is observed by looking at the maximum value of the positioning element. When the first elastic element is a tension spring, it is located on the side of the sealing element closer to the second end; when it is a compression spring, it is located on the side closer to the first end.

[0007] Preferably, it further includes a rod threadedly connected to the second end, a connector rotatably connected to the rod, and an abutment fixedly disposed inside the cylindrical member. The connector is located inside the cylindrical member, and both ends of the first elastic member are respectively connected to the connector and the sealing member. The abutment is located on the side of the sealing member close to the first elastic member.

[0008] When setting up the rod, the first elastic element is set as a tension spring. When the rod rotates relative to the second end, it drives the connecting part to move towards the second end. At this time, the sealing part is blocked by the abutment and cannot move, which can stretch the first elastic element, thereby increasing the moving resistance of the sealing part, and thus adjusting the inhalation resistance of the breathing training and improving the training effect.

[0009] Preferably, the one-way valve assembly includes a mounting member connected to the cylindrical member, an air-blocking member, and a second elastic member whose two ends are respectively connected to the mounting member and the air-blocking member. The cylindrical member is provided with a first air outlet, the air-blocking member is disposed at the first air outlet, the second elastic member is located on the side of the air-blocking member away from the first air outlet, and the mounting member is provided with a second air outlet.

[0010] The air-blocking component, under the elastic force of the second elastic element, adheres tightly to the second air outlet. When the user inhales, the air-blocking component cannot move; when the user exhales, the air-blocking component moves away from the first air outlet, and the second air outlet connects to the first inlet. Airflow flows out sequentially from the first and second air outlets, thus achieving the function of a one-way valve. Furthermore, the one-way valve assembly also includes an adjustment component that can adjust the compression of the second elastic element, thereby adjusting the blowing resistance and improving the training effect. The specific structure of the adjustment component can be referenced from the aforementioned rod and connecting component settings. Furthermore, the air-blocking component is a spherical component.

[0011] Preferably, the cylindrical component is provided with two first air outlets, and each first air outlet is connected to the one-way valve assembly.

[0012] The system is equipped with two primary air outlets and two one-way valve assemblies to increase the air output.

[0013] Preferably, the cylindrical component includes a first cylindrical component, a communicating vessel communicating with the first cylindrical component, and a second cylindrical component communicating with the communicating vessel. The axes of the first cylindrical component and the second cylindrical component coincide, the axis of the communicating vessel is perpendicular to the axis of the first cylindrical component, and the axes of the two first air outlets coincide and are respectively disposed at both ends of the communicating vessel.

[0014] Setting up a communicating vessel facilitates gas flow, and when using it, placing the axis of the communicating vessel horizontally will improve the training effect.

[0015] Preferably, it further includes a magnetic component that is slidably connected to the outer surface of the cylindrical component, and the positioning component is made of a ferromagnetic material.

[0016] When in use, the magnet is far away from the positioning component. When the positioning component needs to be reset, it can be reset by gravity or by sliding the magnet and using the magnetic force of the magnet to drive the positioning component to reset.

[0017] Preferably, the magnet is a ring-shaped component.

[0018] The magnet is ring-shaped, making it easier to set up and use.

[0019] Preferably, the positioning member has a guide portion at one end near the first end.

[0020] The guide section is used to reduce wind resistance near the first end of the positioning component, thus reducing the likelihood of the positioning component being blown away during breathing training. Furthermore, the guide section can be a guide surface, an air guide groove, or an air guide hole.

[0021] Preferably, it also includes an air nozzle connected to the first end.

[0022] With the air nozzle installed, users can replace it after each use, making it more hygienic. Furthermore, the air nozzle is made of a flexible material, which better conforms to the user's mouth.

[0023] Preferably, the air nozzle is fitted onto the first end and has a flared opening.

[0024] The air nozzle is flared to better fit the user's mouth and ensure a tight seal.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. The sealing element creates a negative pressure inside the cylindrical component, which allows the user's inhalation rate to be measured. Combined with the one-way valve assembly that can only exhale, the user can perform continuous inhalation and exhalation, thereby achieving the effect of breathing training. The effect of breathing training can be judged by observing the maximum value of the positioning element during breathing training.

[0027] 2. A lever is set up to pull the first elastic element, which can adjust the movement resistance of the sealing line, thereby adjusting the intensity of breathing training and making it more convenient to use. Attached Figure Description

[0034] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0035] Example 1

[0036] like Figures 1-2 As shown, an inhalation velocity measuring instrument with training function includes: a cylindrical component 1, a sealing component 2 and a positioning component 3 respectively slidably connected to the cylindrical component 1, a first elastic component 4 connected to the sealing component 2 and the cylindrical component 1 at both ends respectively, and a one-way valve assembly 5. The sealing component 2 and the positioning component 3 are both located inside the cylindrical component 1. The one-way valve assembly 5 is connected to the cylindrical component 1 and unidirectionally discharges air. The cylindrical component 1 is provided with a first end for inhalation or exhalation and a second end for connecting to external air pressure. The positioning component 3 and the one-way valve assembly 5 are both located on the side of the sealing component 2 near the first end. The cylindrical component 1 is made of transparent material and has scale lines on its outer surface.

[0037] In use, the cylindrical component 1 must maintain a horizontal axis. The sealing component 2 is located inside the cylindrical component 1 and seals against the inner wall of the cylindrical component 1, thus isolating the gas on both sides of the sealing component 2. The one-way valve assembly 5 is configured to allow only air to exit and not enter. When the user's mouth is fully in contact with the first end and inhales, the gas on the side of the sealing component 2 near the first end inside the cylindrical component 1 is drawn away, creating a negative pressure. Meanwhile, the side of the sealing component 2 near the second end inside the cylindrical component 1 is connected to the external atmosphere. Therefore, the sealing component 2 will move towards the first end under the negative pressure, simultaneously moving the positioning component 3. At this time, the first elastic component 4 will also be compressed or stretched. Simultaneously, the positioning component 3 is slidably connected to the cylindrical component 1 and abuts against the sealing component 2. The cylindrical component 1 is made of transparent material. When the user stops inhaling, the first... The elastic element 4 causes the sealing element 2 to reset, while the positioning element 3 remains inside the cylindrical element 1. The scale lines on the side of the cylindrical element 1 correspond to different inhalation airflow rates. The user's inhalation airflow rate can be measured by observing the scale lines corresponding to the positioning element 3. When the user performs continuous breathing training, after inhaling, the user exhales, and the exhaled air flows out through the one-way valve assembly 5. When inhaling again, the one-way valve assembly 5 is blocked again, and negative pressure is formed inside the cylindrical element 1 again. During this process, the user may blow the positioning element 3 while exhaling, causing the positioning element 3 to move dynamically back and forth. The user can judge the effectiveness of the breathing training by observing the maximum value of the positioning element 3, i.e., the position closest to the first end. Of course, regardless of whether the positioning element 3 is blown during breathing training, the training effect is observed by observing the maximum value of the positioning element 3. Specifically, when the first elastic element 4 is a tension spring, it is located on the side of the sealing element 2 closer to the second end; when the first elastic element 4 is a compression spring, it is located on the side closer to the first end.

[0038] The beneficial effects of this embodiment are: the sealing element 2 is set so that negative pressure can be formed inside the cylindrical element 1, thereby allowing the user's inhalation flow rate to be measured. With the cooperation of the one-way valve assembly 5 which can only exhale, the user can perform continuous inhalation and exhalation, thereby achieving the effect of breathing training. The effect of breathing training can be judged by observing the maximum value of the positioning element 3 during breathing training.

[0039] Example 2

[0040] The difference between Example 1 and Example 2 is as follows:

[0041] like Figures 1-3As shown, it also includes a rod 6 threaded to the second end, a connector 7 rotatably connected to the rod 6, and an abutment 8 fixedly disposed inside the cylindrical member 1. The connector 7 is located inside the cylindrical member 1. The two ends of the first elastic member 4 are respectively connected to the connector 7 and the sealing member 2. The abutment 8 is located on the side of the sealing member 2 near the first elastic member 4. The one-way valve assembly 5 includes a mounting member 501 connected to the cylindrical member 1, an air-blocking member 502, and a second elastic member 503 connected at both ends to the mounting member 501 and the air-blocking member 502 respectively. The cylindrical member 1 is provided with a first air outlet 1021. The air-blocking member 502 is disposed at the first air outlet 1021. The second elastic member 503 is located on the side of the air-blocking member 502 away from the first air outlet 1021. The mounting member 501 is provided with a second air outlet 5011. The cylindrical member 1 is provided with two first air outlets 1021, and each first air outlet 1021 is connected to the one-way valve assembly 5. The cylindrical component 1 includes a first cylindrical component 101, a communicating vessel 102 communicating with the first cylindrical component 101, and a second cylindrical component 103 communicating with the communicating vessel 102. The axes of the first cylindrical component 101 and the second cylindrical component 103 coincide, the axis of the communicating vessel 102 is perpendicular to the axis of the first cylindrical component 101, and the axes of the two first air outlets 1021 coincide and are respectively disposed at both ends of the communicating vessel 102.

[0042] When the rod 6 is set, the first elastic element 4 is a tension spring. When the rod 6 rotates relative to the second end, it drives the connecting element 7 to move towards the second end. At this time, the sealing element 2 is blocked by the abutment element 8 and cannot move, thereby stretching the first elastic element 4, increasing the moving resistance of the sealing element 2, and thus adjusting the inhalation resistance of the breathing training, improving the training effect. The air-blocking element 502 is tightly attached to the second air outlet 5011 under the elastic force of the second elastic element 503. When the user inhales, the air-blocking element 502 cannot move. When the user exhales, the air-blocking element 502 moves away from the first air outlet 1021. The second air outlet 5011 is connected to the first inlet, and the airflow flows out from the first air outlet 1021 and the second air outlet 5011 in sequence, thus realizing the function of a one-way valve. Furthermore, the one-way valve assembly 5 also includes an adjustment component that can adjust the compression of the second elastic element 503, thereby adjusting the blowing resistance and improving the training effect. The specific structure of the adjustment component can be referred to the above-mentioned settings of the rod 6 and the connecting element 7. Furthermore, the air-blocking component 502 is a spherical component. Two first air outlets 1021 and two one-way valve assemblies 5 are provided to increase the air output. The communicating vessel 102 facilitates gas flow, and when in use, placing the axis of the communicating vessel 102 horizontally improves training effectiveness.

[0043] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

[0044] Example 3

[0045] Based on Example 1 or Example 2, Example 1 or Example 2 are further defined, with the following differences:

[0046] like Figures 1-3 As shown, it also includes a magnet 9 that is slidably connected to the outer side of the cylindrical member 1, and the positioning member 3 is made of ferromagnetic material. The magnet 9 is a ring-shaped member. A guide portion 301 is provided at one end of the positioning member 3 near the first end. It also includes an air nozzle 10 connected to the first end. The air nozzle 10 is fitted onto the first end and has a flared opening.

[0047] When in use, the magnet 9 is away from the positioning element 3. When the positioning element 3 needs to be reset, it can be reset by gravity or by sliding the magnet 9, using the magnetic force of the magnet 9 to drive the positioning element 3 to reset. The magnet 9 is a ring-shaped part for easier installation and use. The guide part 301 is used to reduce the wind resistance of the positioning element 3 near the first end, reducing the chance of the positioning element 3 being blown away during breathing training. Furthermore, the guide part 301 is a guide surface, air guide groove, or air guide hole. After the air nozzle 10 is installed, the user can replace the air nozzle 10 after use, making it more hygienic. Furthermore, the air nozzle 10 is made of flexible material, which is more conducive to fitting the user's mouth. The air nozzle 10 is flared to further fit the user's mouth and ensure a tight seal.

[0048] The remaining working principles and processes of this embodiment are the same as those of Embodiment 1 or Embodiment 2.

For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
