1 and 2 are perspective views showing a spirometer in one embodiment. 3 is a cross-sectional view showing a spirometer in one embodiment. The spirometer is a device for measuring the user's lung capacity or assisting patients in rehabilitation.

For example, the spirometer of the embodiment can roughly measure the amount of air that the user can inhale maximum, ie, the spirometer when inhaling once. Therefore, the spirometer of the embodiment measures the user's lung capacity, and allows the user to perform breathing training while grasping how much the lung capacity is when receiving respiratory-related rehabilitation treatment.

The spirometer of the embodiment includes a base 100, a cylinder 200, a ventilation pipe 300, a support 400, a flexible hose 500 (flexible hose), a mouthpiece 600, a holder 700, a plotter 800 ( floater) and the opening/closing lever 900.

The base 100, the cylinder 200 is disposed on the upper surface, can serve to support the configuration of the cylinder 200, the ventilation pipe 300, the support 400, etc. Referring to Figure 1, the spirometer It can serve as a support for stable positioning on the floor.

The cylinder 200 may be disposed on the base 100. The cylinder 200 may serve to temporarily store air required for the user to breathe. A first through hole 210 is formed under the cylinder 200, and an upper end of the cylinder 200 may communicate with the first communication unit 310.

Therefore, as illustrated by the arrow in FIG. 3, when the user inhales air through the mouthpiece 600, external air is introduced into the cylinder 200 through the first through hole 210 and the top of the cylinder 200 Through it may be introduced back to the first communication unit 310. To effectively implement the role of the cylinder 200, for example, the cylinder 200 may be provided in plural.

The ventilation pipe 300 is formed with a passage through which air can flow, and gas can flow through the passage. 1 and 2, the ventilation pipe 300 may include a first communication portion 310 and a second communication portion 320.

The first communication unit 310 may communicate with one side of the cylinder 200. Therefore, for communication between the cylinder 200 and the first communication unit 310, an opening may be provided at the top of the cylinder 200. Of course, the first communication unit 310 may have a passage through which air flows.

The second communication unit 320 may communicate with the first communication unit 310 and bend with respect to the first communication unit 310, and one side may be combined with the base 100. The second communication unit 320 may be integrally formed with the first communication unit 310. Of course, a passage through which the gas flows may also be formed in the second communication unit 320.

In another embodiment, the first communication unit 310 and the second communication unit 320 are separately formed, and the first communication unit 310 and the second communication unit 320 may be detachably attached to each other. In this case, openings may be formed in each of the first communication unit 310 and the second communication unit 320 for communication between the first communication unit 310 and the second communication unit 320.

On the other hand, the second communication unit 320 is mounted on one side of the flexible hose 500, a hose connection 501 may be formed in communication with the flexible hose 500. For example, the second communication unit 320 may be designed such that the flexible hose 500 is detachably attached to the ventilation port of the second communication unit 320.

Referring to FIGS. 2 and 3, a second through hole 321 may be formed in the second communication part 320 to introduce external air into the flow path inside the second communication part 320. Therefore, when the second through hole 321 is opened, as illustrated by the arrow in FIG. 3, air flows into the second communication part 320 from the first communication part 310 and the second through hole 321 simultaneously. Can be.

One side of the support 400 may be coupled to the base 100, and the other side may be coupled to the first communication portion 310. The support 400 may stably support the first communication unit 310.

Accordingly, as illustrated in FIGS. 1 to 3, a plurality of cylinders 200 may be disposed in a space formed by the first communication unit 310, the second communication unit 320, and the support 400. . The support 400 is formed integrally with the base 100, the cylinder 200, the first communication unit 310 and the second communication unit 320, the cylinder 200, the first communication unit 310 and It may be provided to more stably support the second communication unit 320.

The flexible hose 500 may be provided to communicate with the second communication part 320 and be deformable. 1 to 3, one side of the flexible hose 500 is coupled and communicated with the second communication part 320 at the hose connection part 501, and the mouthpiece 600 can be coupled to the other side. .

The user can comfortably use the spirometer by deforming the deformable flexible hose 500.

The mouthpiece 600 may be coupled to one side of the flexible hose 500. The user can breathe through the mouthpiece 600.

For example, when the user inhales through the mouthpiece 600, the air from the cylinder 200, the first communication unit 310, the second communication unit 320, the flexible hose 500 and the mouthpiece ( 600), and also, when the second through hole 321 is opened, additional air from the outside through the second through hole 321 to the second communication part 320, the flexible hose 500 and the mouthpiece 600 By flowing, the user can inhale air.

The cradle 700 may be coupled so that the mouthpiece 600 is detachable, and may be disposed on the base 100. However, the cradle 700 may be disposed at another suitable location of the spirometer in addition to the base 100.

The holder 700 may be provided in a hollow shape with an opening formed on one side so that the mouthpiece 600 can be coupled. Therefore, by fitting the mouthpiece 600 into the opening of the cradle 700, the mouthpiece 600 can be coupled to the cradle 700.

At this time, the mouthpiece 600 may be coupled to the cradle 700 by, for example, a shape fit or a force fit method. That is, the mouthpiece 600 may be inserted into an opening formed in the cradle 700 in a shape-fitting or forced fit manner to be accommodated in the hollow of the cradle 700.

Therefore, the user can easily attach the mouthpiece 600 to the cradle 700 and also detach the mouse from the cradle 700.

When the holder 700 is provided, it is possible to effectively suppress the damage of the spirometer, particularly the flexible hose 500 and the mouthpiece 600 when the spirometer is stored. In addition, when the mouthpiece 600 is moved, the user's inconvenience can be effectively resolved, and the exposure of the mouthpiece 600 can be suppressed to suppress the occurrence of infection.

The floater 800 is accommodated inside the cylinder 200 and may be provided to be movable in the longitudinal direction of the cylinder 200. Since the plotter 800 is provided lightly compared to the volume, when the user inhales air, it can be pressurized by the air flowing from the first through hole 210 to the top of the cylinder 200 inside the cylinder 200.

For example, the plotter 800 may be formed of a plastic having a small specific gravity, and may be provided in a hollow spherical shape or provided in a hollow cylindrical shape, so that the mass to volume ratio is small.

In an embodiment, the outer wall of the cylinder 200 is formed of a transparent or translucent material, so that the user can observe whether the floater 800 rises and the number of rising floaters 800, through which the user has his lung capacity Can be seen.

For example, in the exemplary embodiment, three cylinders 200 are arranged in parallel, and the number and rise width of the plotter 800 rising may vary according to the maximum amount of air intake that the user inhales once. The user can observe this and know the maximum amount of air that can be inhaled at a time, that is, the amount of lung activity.

Referring to FIG. 3, when a user inhales air, the plotter 800 accommodated in the A cylinder having the shortest flow path length measured from the first through 210 to the hose connection part 501 among the A to C cylinders rises first. .

When the amount of air intake increases, the floater 800 accommodated in the cylinder A moves to the top of the cylinder 200, and when the amount of air intake increases further, the length of the flow path is longer than that of the cylinder A, and the cylinder B is the longest. The plotter 800 accommodated in the cylinder sequentially rises.

Therefore, in the design of the spirometer, the air intake amount corresponding to the case where the plotter 800 of the A cylinder rises to the top, and the air intake amount corresponding to the case where the plotter 800 of the A and B cylinders rises to the top, A, B and C By pre-calculating the amount of air intake corresponding to the case where the floater 800 of the cylinder rises to the top, the user can observe the rising number and the degree of rise of the floater 800 to know his own lung capacity.

If, as a result of the user inhaling the air at the maximum through the mouthpiece 600, the floater 800 of the A-cylinder rises to the top, the user can be regarded as having a lung capacity equal to or greater than the air intake corresponding to this case. .

Therefore, the user can measure his own lung capacity by using the spirometer of the embodiment, and can also perform breathing training while grasping the extent of the lung capacity when receiving rehabilitation treatment.

On the other hand, the spirometer cannot measure the spirometer exceeding the case where the plotters 800 of all cylinders 200 all rise to the top of the cylinder 200. Under these constraints, it is necessary to widen the range of spirometric measurement of the spirometer.

That is, in the case of a patient receiving rehabilitation treatment, since the lung capacity may be less than 10% compared to a normal person, it is necessary to widen the measurement range of the spirometer to allow various users to use the spirometer in various cases.

To this end, a second through hole 321 is formed in the second communication portion 320 to allow air to flow into the pulmonary circulator from a portion other than the cylinder 200, thereby widening the measurement range of the spirometer. In addition, by adjusting the opening rate of the second through hole 321 to control the amount of air flowing into the second through hole 321, it is also possible to control the range of measurable lung capacity.

In other words, as the opening degree of the second through hole 321 increases, the amount of air flowing into the second through hole 321 increases, and accordingly, both a minimum value and a maximum value of measurable lung capacity may increase.

For example, referring to FIG. 5, the opening degree of the second through hole 321 may be set to 0 to 4. 0 is when the second through hole 321 is closed, and 4 is when the second through hole 321 is opened to the maximum. That is, the opening degree of the second through hole 321 increases sequentially starting from 0 to 4 as it is closed.

When the second through hole 321 is closed, when the plotter 800 of the cylinder A starts to rise, the spirometer becomes the minimum spirometer that can be measured, and the plotter 800 of the A, B, and C cylinders is all cylinders. (200) This is the maximum spirometer that the spirometer can measure when rising to the top.

When the second through hole 321 is closed, a range from a minimum spirometer to a maximum spirometer that can be measured by the spirometer is referred to as a zero-order range. Similarly, when the opening degree of the second through hole 321 is 1 to 4, the range from the minimum pulmonary capacity that the spirometer can measure to the maximum pulmonary capacity is referred to as the 1st to 4th range.

Therefore, the spirometer of the embodiment may have a pulmonary capacity measurement range of 0 to 4 th order by having a second through hole 321 and adjusting the opening degree of the second through hole 321. The maximum value of the 0th range is less than the minimum value of the 1st range, the maximum value of the 1st range is less than the minimum value of the 2nd range, the maximum value of the 2nd range is less than the minimum value of the 3rd range, and the maximum value of the 3rd range The value may be smaller than the minimum value in the fourth order range.

In an embodiment, the second through hole 321 is formed in the spirometer and by adjusting the opening degree of the second through hole 321, the range of the spirometer that the spirometer can measure can be widened and multi-staged.

Due to this, in the embodiment, the measurement range of the spirometer is widened, so that various users can use the spirometer in various cases.

4 is an enlarged view of part A of FIG. 3. 5 is a perspective view of FIG. 4. 6 is a side view of FIG. 5. 7 is a view showing the opening and closing lever 900 of one embodiment. 4 to 6, the second through hole 321 has a state of opening 4.

The opening/closing lever 900 may be coupled to the second communication portion 320 to adjust the opening degree of the second communication hole 321. At this time, the opening degree of the second through hole 321 means the size of the area where the second through hole 321 is opened to the outside. When the opening degree of the second through hole 321 is large, the open area of the second through hole 321 is large, and when the opening degree is small, the area is small.

As the opening degree of the second through hole 321 increases, the hourly flow rate of air flowing into the second communicating part 320 through the second through hole 321 increases, and thus, the minimum and maximum pulmonary capacity that the spirometer can measure. All values increase.

In the embodiment, the second through hole 321 has an opening degree of 0 to 4, and 0 is a state in which the second through hole 321 is closed. When the second through hole 321 has an opening degree of 4, both the minimum spirometer value and the maximum spirometer value that the spirometer can measure become maximum. In an embodiment, the opening degree of the second through hole 321 is not limited to 0 to 4, and may have 0 to 1, 0 to 2, 0 to 3, or 0 to 5 or other values.

As shown in FIG. 7, the opening/closing lever 900 may include an opening/closing part 910, a connecting part 920, and a gripping part 930.

The opening/closing portion 910 may slide with respect to the second communication portion 320 to adjust the open area of the second communication hole 321. The opening/closing portion 910 is provided in a plate shape, and slides with respect to the second communication portion 320 to cover part or all of the second through hole 321 to adjust the size of the opened area of the second through hole 321, that is, the opening degree. You can.

In another embodiment, the opening and closing portion 910 is provided in an arc shape having a constant width, and rotates with respect to the second communication portion 320 to cover a part or all of the second through hole 321 to cover the second through hole 321 The size of the open area, that is, the opening degree can be adjusted. In this case, the shape of the second through hole 321 may be provided in an arc shape corresponding to the opening and closing portion.

The connection part 920 may be coupled to the opening/closing part 910 on one side but protruding from the opening/closing part 910, and the other side may be combined with the gripping part 930. The gripping portion 930 is bent from the connecting portion 920, and the user can manipulate the movement of the opening/closing lever 900 by moving the gripping portion 930. The gripping portion 930 may form a concavo-convex portion on the surface so that the user can easily grip it using a finger or the like.

In an embodiment, the opening/closing portion 910, the connecting portion 920, and the gripping portion 930 may be integrally formed through, for example, injection molding.

The second communication unit 320 is equipped with an opening/closing lever 900 so that the opening degree of the second through hole 321 can be easily adjusted, as shown in FIGS. 4 and 5, the mounting groove 321 and the protrusion ( 323) may be formed.

The mounting groove 321 is formed on the wall surface forming the second through hole 321, and the opening/closing part 910 is mounted to provide a moving space. For example, the mounting groove 321 may be formed by recessing a part of the wall surface forming the second through hole 321.

 Mounting groove 321 is formed to have a shape and size corresponding to the opening and closing portion 910, it may be formed to have an appropriate clearance (clearance) so that the opening and closing portion 910 can move smoothly.

The protrusion 323 may be formed to protrude on a portion of the wall surface forming the second through hole 321 that does not overlap the mounting groove 321. The protrusion 323 may be formed, for example, on a portion of the inner wall of the second through hole 321 that is in sliding contact with the connection part 920.

At this time, the projection 323 may limit the free movement of the opening/closing lever 900 by pressing the connecting portion 920. That is, since the protrusion 323 protrudes toward the connection portion 920, the opening/closing lever 900 cannot freely move due to a load or a slight external impact, and the user applies a force of a certain level or more to the gripping portion 930. The movable opening and closing lever 900 can be moved by sliding on the second communication unit 320.

The protrusion 323 has a separation distance set in a moving direction of the opening/closing lever 900 and may be provided in multiple stages. At this time, as the protrusion 323 presses the connecting portion 920 at each end to limit the free movement of the opening/closing lever 900, the opening/closing lever 900 opens the opening degree of the second through hole 321. Can be adjusted.

For example, referring to FIG. 5, when the user pushes the gripping part 930 by applying a certain degree of force, the entire opening/closing lever 900 moves upward to change the opening degree of the second through hole 321 from 4 to 3 When the user leaves it as it is, the opening/closing lever 900 does not move downward due to the pressing force of the projection 323 to the connection portion 920, and the position of the opening degree 3 is maintained.

Again, when the user pushes the gripping part 930 by applying a force greater than the pressing force of the protrusion 323, the entire opening/closing lever 900 moves upward and the opening degree of the second through hole 321 may be changed from 3 to 2. .

With the above-described structure, the user adjusts the opening degree of the second through hole 321 by pushing the gripping part 930 up or down with a certain degree of force or moving the opening/closing lever 900 up and down, thereby measuring the spirometer. The range of lung capacity that can be done can be multi-staged.

Although only a few have been described as described above in connection with the embodiments, various other forms of implementation are possible. The technical contents of the above-described embodiments may be combined in various forms, unless the technologies are incompatible with each other, and may be implemented as a new embodiment.
