Description

Technical Field

[0001] This application relates to the field of medical detection technologies, and particularly to a peak flow meter. Background Art

[0002] A peak flow meter is a commonly used respiratory system detection device that can measure the peak flow rate when a patient exhales, thereby evaluating the patient's respiratory tract condition. Existing peak flow meters typically include a measuring tube and an indicator. The patient blows air to move a float inside the measuring tube, and the indicator shows the corresponding peak flow rate value.

[0003] However, existing peak flow meters mainly observe the movement range of the float by driving the indicator through the movement of the float. Inevitably, errors occur during actual use. The main problem is that the movement of the float in the measuring tube causes significant wear, and long-term use will exacerbate the wear and thus affect the actual detection results. Utility Model Content

[0004] To improve the low accuracy of the detection results of existing peak flow meters, this application provides a peak flow meter.

[0005] This application provides a peak flow meter, including a measuring component and a display component installed on the measuring component. The measuring component includes a measuring tube, and two symmetrically arranged arc-shaped openings are provided on the outer wall of the measuring tube. Detection components one and two are respectively arranged on the inner walls of the two arc-shaped openings in a symmetric manner, and acrylic plates are fixedly connected to the inner walls of the two arc-shaped openings. An installation sleeve is fixedly connected to the inner wall of the measuring tube, and a float is arranged on the inner wall of the installation sleeve.

[0006] With the above structure, the accuracy of the detection results of the measuring component can be conveniently improved through multiple sensors in the measuring component. The display component is provided to display the data measured by the measuring component in real time. The arc-shaped openings are provided to facilitate the installation of detection components one and two, and detection components one and two are symmetrically arranged. The acrylic plates are provided to facilitate the closure of the arc-shaped openings.

[0007] Two grooves are provided on the inner wall of the installation sleeve, and slide rails are fixedly connected to the inner walls of the two grooves. The float is slidably connected to the two slide rails.

[0008] With the above structure, the slide rails can be conveniently installed through the grooves on the installation sleeve.

[0009] Two symmetrically arranged openings are provided on the outer wall of the installation sleeve, and indicator blocks are slidably connected to the inner walls of the two openings.

[0010] With the above structure, the indicator blocks can be slidably installed through the openings.

[0011] Both of the two indicating blocks are fixedly connected to the float, and one end of the measuring tube is fixedly connected with an air inlet pipe.

[0012] With the above structure, the position of the float is conveniently indicated through the setting of the indicating block, and the gas is conveniently introduced into the measuring tube through the setting of the air inlet pipe.

[0013] The air inlet pipe is communicated with the measuring tube, and an exhaust port is arranged at the other end of the measuring tube.

[0014] With the above structure, the gas entering the measuring tube is conveniently discharged through the arrangement of the exhaust port at one end of the measuring tube.

[0015] The display component includes a mounting plate fixedly connected to the measuring tube, and a display screen is fixedly connected to the outer wall of the mounting plate.

[0016] With the above structure, the display screen is conveniently mounted on the measuring tube through the setting of the mounting plate.

[0017] The first detection component includes a first detection seat fixedly connected to the inner wall of the arc-shaped opening. An installation groove one is arranged on the outer wall of one side of the first detection seat, and a photoelectric sensor transmitter is fixedly connected to the inner wall of the installation groove one.

An installation groove two is arranged on the outer wall of one side of the second detection seat, and a photoelectric sensor receiver is fixedly connected to the inner wall of the installation groove two.

[0018] With the above structure, the laser emitted by the photoelectric sensor transmitter is received by the photoelectric sensor receiver. When the float moves between the photoelectric sensor transmitter and the photoelectric sensor receiver, the laser will be blocked. When the float leaves, the laser is received by the receiver again. The photoelectric sensor can detect the time when the laser is blocked, so as to conveniently measure the moving speed of the float.

[0019] Both the photoelectric sensor receiver and the photoelectric sensor transmitter are electrically connected to the display screen.

[0020] With the above structure, through the electrical connection between the display screen, the photoelectric sensor receiver and the photoelectric sensor transmitter, it is convenient to display the detected data in real time.

The measuring component 1 includes a measuring tube 8, and two symmetrically arranged arc-shaped openings 10 are formed on the outer wall of the measuring tube 8. Three symmetrically arranged first detection components 5 and second detection components 9 are respectively arranged on the inner walls of the two arc-shaped openings 10, and acrylic plates 4 are fixedly connected to the inner walls of the two arc-shaped openings 10. An installation sleeve 12 is fixedly connected to the inner wall of the measuring tube 8, and a float 13 is arranged on the inner wall of the installation sleeve 12.

[0033] During use, the multiple sensors in the measuring component 1 facilitate improving the accuracy of the detection results of the measuring component 1. The display component 2 is set to display the data measured by the measuring component 1 in real time. The arc-shaped opening 10 facilitates the installation of the first detection component 5 and the second detection component 9, and the first detection component 5 and the second detection component 9 are symmetrically arranged. The acrylic plate 4 facilitates the closure of the arc-shaped opening 10.

[0034] Refer to Figure 4 , two grooves are provided on the inner wall of the mounting sleeve 12, and slide rails 15 are fixedly connected to the inner walls of the two grooves. The float 13 is slidably connected to the two slide rails 15. The grooves on the mounting sleeve 12 facilitate the installation of the slide rails 15.

[0035] Refer to Figure 3 and Figure 4 , two symmetrically arranged openings 14 are provided on the outer wall of the mounting sleeve 12, and indicating blocks 17 are slidably connected to the inner walls of the two openings 14. The arrangement of the openings 14 facilitates the sliding installation of the indicating blocks 17.

[0036] Refer to Figure 3 , both of the two indicating blocks 17 are fixedly connected to the float 13. One end of the measuring tube 8 is fixedly connected to an air inlet pipe 3. The arrangement of the indicating blocks 17 facilitates indicating the position of the float 13, and the arrangement of the air inlet pipe 3 facilitates introducing gas into the measuring tube 8.

[0037] Refer to Figure 2 , the air inlet pipe 3 is communicated with the measuring tube 8, and the other end of the measuring tube 8 is provided with an exhaust port. The arrangement of the exhaust port at one end of the measuring tube 8 facilitates discharging the gas entering the measuring tube 8.

[0038] Refer to Figure 2 , the display component 2 includes a mounting plate 6 fixedly connected to the measuring tube 8, and a display screen 7 is fixedly connected to the outer wall of the mounting plate 6. The arrangement of the mounting plate 6 facilitates mounting the display screen 7 on the measuring tube 8.

[0039] Refer to Figures 5-6, the detection component 5 includes a first detection seat 18 fixedly connected to the inner wall of the arc-shaped opening 10, and an installation groove 1 is formed on the outer wall of one side of the first detection seat 18. A photoelectric sensor transmitter 19 is fixedly connected to the inner wall of the installation groove 1.

[0041] The implementation principle of this application is as follows: When in use, when the peak flow meter is needed, first turn on the switch on the display component 2, and then the user holds the intake pipe 3 and blows air. When the exhaled gas enters the measuring pipe 8, it directly pushes the float 13 to move. When the float 13 moves, it directly drives the indicating block 17 to move. When the float 13 moves between the corresponding detection component 5 and the detection component 9, it will block the laser emitted by the photoelectric sensor transmitter 19. When the photoelectric sensor receiver 21 cannot receive the laser, it will be directly triggered. By setting the photoelectric sensor, the speed of the float 13 can be detected. The setting of multiple detection components improves the accuracy of the detection results.
