[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Combined with attachment Figures 1-4 In this embodiment, a high-precision vital capacity testing device includes: a tester 1, which is a rectangular parallelepiped structure; an adapter device 7, which is installed on the left side of the outside of the tester 1. The internal setting of the adapter device 7 can ensure that there is no other impurities in the pipeline when testing vital capacity, thereby improving the high-precision measurement results of the vital capacity testing device; an exhalation plug 10, which is installed above the tester 1, and the exhalation plug 10 transmits the entire exhalation port in a closed form to avoid air leakage that affects the measurement results.

[0036] Specifically, because air leakage often occurs in the vital capacity test device during the test, once the air leakage occurs, the measurement result will be affected. Therefore, a device for tightening the internal part of the exhalation plug 10 is used to improve the sealing performance, so that the measurement result can be more accurate.

[0037] To facilitate a thorough understanding of the specific structure and principles of the tester 1 by those skilled in the art, the tester 1 is further described. In this embodiment, the tester 1 includes: a regulator 2, which is located on the left and right sides of the front of the tester 1. A sensor line 3 is mounted above the tester 1, and a display screen 4 is mounted in the middle of the sensor line 3; a player 5, which is located on the left and right sides of the top of the tester 1. A side instrument interface 6 is mounted on the left side of the exterior of the tester 1, and a lower spring tube 8 is mounted to the left of the side instrument interface 6; and an upper fixed tube 9, which is mounted above the lower spring tube 8. The tester 1 also includes: an internal groove 101, which is installed at the internal front of the tester 1, and movable plugs 102 are installed on the left and right sides of the interior, and a precision test tube 103 is provided in front of the movable plug 102; a small notch 104, which is provided below the internal groove 101; a small protrusion 105, which is provided above the bottom of the internal groove 101; a fixture mouth 106, which is installed above the surface of the tester 1, and a vital capacity internal receiving cover 107 is installed above the fixture mouth 106; the small notch 104 and the small protrusion 105 are the same in size and depth, the vital capacity internal receiving cover 107 is connected to the tester 1 through the fixture mouth 106, and the movable plug 102 is connected to the sensor line 3 through the precision test tube 103.

[0038] In the tester 1, the test results can be viewed in real time through the display screen 4, and can also be compared with the previous results. In addition, the speed of movement of the movable plug 102 inside the tester 1 can directly indicate the size of the vital capacity. The simplicity and convenience of this device can be used to test the vital capacity results more accurately.

[0039] To facilitate those skilled in the art to fully understand the specific structure and principle of the adapter device 7, the adapter device 7 is further described. In this embodiment, the adapter device 7 includes: an adapter internal shaft 701, which is disposed above the adapter device 7, and is provided with a bayonet 702 around the four sides of the adapter internal shaft 701, and an inner tube hole 703 is installed inside the adapter internal shaft 701; an inner tube purifier 704, which is installed inside the inner tube hole 703; the diameter of the adapter internal shaft 701 is 1.5 times the diameter of the inner tube hole 703, and the bayonet 702 is embedded on the outside of the adapter internal shaft 701.

[0040] In the adapter 7, the bayonet 702 is fully connected to the lower spring tube 8, and the tube purifier 704 provided in the bayonet 702 purifies the lower spring tube 8 from gas and impurities, preventing other factors from affecting the test results and maintaining the purification level inside the lower spring tube 8;

[0041] To facilitate a thorough understanding of the specific structure and principles of the exhalation plug 10 by those skilled in the art, further description is provided below. In this embodiment, the exhalation plug 10 comprises an inner ring 1001 disposed within the exhalation plug 10. A bayonet 1002 is disposed within the inner ring 1001, and an exhalation tube 1003 is mounted in the center of the bayonet 1002.

[0042] In the exhalation plug 10, the range of the exhalation plug 10 is reduced by using the breathing plug inner ring 1001 installed inside the exhalation plug 10, and then the bayonet dish 1002 is sealed and connected, mainly to prevent air leakage at the first exhalation level.

[0043] Working principle: First, install the adapter device 7 on the left side of the side instrument interface 6, and then install the lower spring tube 8 above the adapter device 7. The bayonet 702 set on the adapter device 7 must be fully connected with the lower spring tube 8 to maintain tightness. Then install the upper solid tube 9 above the lower spring tube 8 and you can do the test. The first step is to insert the exhalation tube 1003 into the upper solid tube 9. After the connection is completed, start to exhale into the exhalation tube 1003. The gas is transmitted to the tester 1 through the upper solid tube 9 and the lower spring tube 8. At this time, the movable plug 102 will move according to the size of the inhaled air. The movable plug 102 moves The slower the speed, the smaller the vital capacity, and the faster the movable plug 102 moves, the larger the vital capacity. After the test is completed, the vital capacity data will be displayed on the display screen 4, and the player 5 will also play the test results. After the test is completed, if the next person still needs to be tested, the exhalation tube 1003 can be unplugged and a new exhalation tube 1003 can be reinserted. While waiting for the test, the purifier 704 in the tube will clean the impurities in the lower spring tube 8 and the upper fixed tube 9, and will not leave air and impurities in the pipe to affect the test results of the next person. In this way, the entire use process of the high-precision vital capacity testing device is completed.

[0044] 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.
