[0026] For this specific embodiment, the tester body 102 is installed on the frame 101. The tester body 102 is used to check the lung ventilation function (diffusion) and lung capacity. The tester body 102 is a prior art, and its structure and working principle are not described in detail here. The bottom of the frame 101 is provided with universal wheels, which is convenient for moving the device. The top of the frame 101 is provided with a display and a keyboard, which is convenient for the operator to record and view the patient's test results. The display intuitively displays the patient's lung function parameters, such as diffusion capacity, residual capacity, vital capacity and other key indicators.

[0027] The connector 104 is connected to the tester body 102 through a pipeline and communicates with the tester body 102. The blowing nozzle 105 is plugged into the connector 104. The rotating seat 106 is rotatably installed on the connector 104 and sleeved on the connector 104. The driving rod 107 is fixedly connected to the rotating seat 106 and is located on the inner side of the rotating seat 106. The sealing airbag 108 is connected to the connector 104 and is located on the inner side of the connector 104. The blowing nozzle 105 has a driving groove 118, which is arranged on a side of the blowing nozzle 105 close to the driving rod 107. The inflatable member 109 is arranged on the connector 104 and inflates the sealing airbag 108. The driving rod 107 and the driving groove 118 are each provided with three, and the driving groove 118 is provided with a straight section and an inclined section. When in use, the blowing nozzle 105 is inserted into the connector 1 04, thereby connecting the air blowing nozzle 105 to the tester body 102, and then inflating the sealing airbag 108 through the inflatable member 109 to expand the sealing airbag 108, thereby sealing the gap between the air blowing nozzle 105 and the connecting head 104 to avoid air leakage, and at the same time improve the stability of the air blowing nozzle 105 on the connecting head 104, at this time, the patient can blow air into the air blowing nozzle 105 and test the lung function through the tester body 102; when the test is completed and the air blowing nozzle 105 needs to be replaced, the medical staff rotates the rotating seat 106 to drive the driving rod 107 to rotate, and the driving rod 107 moves along the inclined section on the driving groove 118 during the rotation, thereby pushing out the air blowing nozzle 105, causing the air blowing nozzle 105 to fall off the connecting head 104, so that the air blowing nozzle 105 can be removed without touching the air blowing nozzle 105, thereby achieving the purpose of avoiding the risk of infection.

[0028] Secondly, the slide groove 110 is arranged on the connecting head 104 and passes through the connecting head 104, and the slide groove 110 cooperates with the connecting head 104; there are three slide grooves 110 and they are evenly distributed on the connecting head 104, and the driving rod 107 passes through the slide groove 110 and extends into the interior of the connecting head 104, and the driving rod 107 is rotated through the slide groove 110, so that the driving rod 107 can slide along the slide groove 110.

[0029] At the same time, the limiting protrusion 111 is arranged on the blowing nozzle 105 and is located on the outside of the blowing nozzle 105; the limiting groove 112 is arranged on the connecting head 104 and is located on the inside of the connecting head 104, and the limiting groove 112 cooperates with the limiting protrusion 111; there are multiple limiting grooves 112 and limiting protrusions 111. When the blowing nozzle 105 extends into the interior of the connecting head 104, the limiting protrusion 111 is inserted into the limiting groove 112. At this time, the blowing nozzle 105 is limited, so that the blowing nozzle 105 cannot rotate on the connecting head 104, thereby improving the stability of the blowing nozzle 105.

[0030] In addition, the connecting groove 113 is arranged on the outside of the blowing nozzle 105 and cooperates with the sealing airbag 108; when the sealing airbag 108 is inflated, the sealing airbag 108 is filled into the connecting groove 113, which not only improves the sealing effect of the blowing nozzle 105 and the connecting head 104, but also further improves the stability of the blowing nozzle 105, thereby preventing the blowing nozzle 105 from falling during use.

[0031] Then, the rotating ring 114 is fixedly connected to the rotating base 106 and sleeved on the rotating base 106 .

[0032] Finally, the ring body 115 is fixedly installed on the outside of the rotating seat 106; the anti-slip protrusion 116 is fixedly connected to the ring body 115 and is located on the outside of the ring body 115; the sealing gasket 117 is connected to the ring body 115, abuts against the connector 104, and is located on the inside of the ring body 115.

[0033] There are multiple anti-slip protrusions 116, which are evenly distributed on the outside of the ring body 115. The anti-slip protrusions 116 are convenient for medical personnel to rotate the ring body 115. The rotating seat 106 is driven to rotate by rotating the ring body 115, which facilitates the rotation of the rotating seat 106. At the same time, the sealing gasket 117 is used to seal the gap between the ring body 115 and the connector 104 to prevent the connector 104 from leaking and affecting the accuracy of the test.

[0034] Second embodiment:

[0035] Based on the first embodiment, please refer to Figure 6 , Figure 6 2 is a schematic diagram of the installation structure of the piston rod of the second embodiment. The inflatable component 109 of this embodiment includes a piston cylinder 201, a piston rod 202 and a connecting pipe 203. The piston rod 202 includes a piston 204, an arc rod 205 and a push plate 206.

[0036] According to this specific embodiment, the piston cylinder 201 is fixedly connected to the connecting head 104 and is located inside the connecting head 104; the two ends of the connecting tube 203 are respectively connected to the sealing airbag 108 and the piston cylinder 201, and the connecting tube 203 is located inside the connecting head 104; the piston rod 202 is fixedly connected to the rotating seat 106, and is slidably connected to the piston cylinder 201, and is located inside the piston cylinder 201.

[0037] Among them, the push plate 206 is fixedly connected to the rotating seat 106 and is located on one side of the rotating seat 106; the arc rod 205 is fixedly connected to the push plate 206 and is located on one side of the push plate 206; the piston 204 is fixedly connected to the arc rod 205, and is slidably connected to the piston cylinder 201, and is located inside the piston cylinder 201.

[0038] There are three inflatable components 109. When the rotating ring 114 is rotated to drive the rotating seat 106 to rotate, the rotating seat 106 drives the push plate 206, the arc rod 205 and the piston 204 to move, so that the piston 204 moves inside the piston cylinder 201. At this time, the piston 204 pushes the air inside the piston cylinder 201 into or out, thereby pushing the air into or out of the sealing airbag 108 through the connecting tube 203, thereby achieving the purpose of expanding or contracting the sealing airbag 108.

[0039] When using the diffuse residual gas pulmonary function tester of this embodiment, when installing the air blowing nozzle 105, align the limiting protrusion 111 on the air blowing nozzle 105 with the limiting groove 112 on the connecting head 104 and insert it. During the insertion process, even if the position of the driving rod 107 is incorrect, the inclined section on the driving groove 118 will drive the driving rod 107 to rotate, thereby driving the rotating seat 106 and the piston rod 202 to rotate, so that the piston 204 moves inside the piston cylinder 201, and the sealing airbag 108 expands. However, at this time, the sealing airbag 108 is not fully expanded and will not interfere with the insertion of the air blowing nozzle 105, so that the air blowing nozzle 105 can be smoothly inserted into the connecting head 104; when the air blowing nozzle 105 is inserted into place, the medical staff rotates the rotating ring 114 again to drive the rotating seat 106 and the piston rod 202 to move, so that the piston 204 pushes the remaining air into the connecting tube 203 and the sealing airbag 108, so that the sealing airbag 108 The airbag 108 is fully inflated, and the sealing airbag 108 is then embedded in the connecting groove 113, thereby sealing the gap between the blowing nozzle 105 and the connecting head 104; when the blowing nozzle 105 needs to be removed, the rotating ring 114 is rotated in the opposite direction, thereby driving the rotating seat 106 and the driving rod 107 to rotate in the opposite direction, and the driving rod 107 first moves along the straight section of the driving groove 118, at which time the blowing nozzle 105 does not move, but the rotating seat 106 is driven to rotate in the opposite direction. The piston rod 202 is moved to extract the air in the sealing airbag 108, so that the sealing airbag 108 shrinks, thereby preventing the sealing airbag 108 from interfering with the removal of the blowing nozzle 105. When the driving rod 107 rotates to the inclined section of the driving groove 118, the driving rod 107 drives the blowing nozzle 105 to move, and then pushes the blowing nozzle 105 out of the connecting head 104, so that the blowing nozzle 105 can be removed without touching it, avoiding the risk of cross infection.

[0040] Third embodiment:

[0041] Based on the first embodiment, please refer to Figure 7 , Figure 7 30 is a schematic diagram of the installation structure of the collection bag of the second embodiment. The diffuse residual gas pulmonary function tester of this embodiment also includes a support frame 301 and a collection bag 302.

[0042] According to this specific embodiment, the support frame 301 is fixedly connected to the frame 101 and is located on one side of the frame 101; the collecting bag 302 is connected to the support frame 301 and is arranged on the support frame 301; when the blowing nozzle 105 needs to be replaced, the medical staff takes the blowing nozzle 105 above the collecting belt, and then rotates the rotating ring 114 to drive the rotating seat 106 to rotate, so that the driving rod 107 pushes the blowing nozzle 105 out, and the blowing nozzle 105 can fall into the collecting bag 302 for collection, thereby achieving the purpose of conveniently collecting the blowing nozzle 105 after use.
