Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a portable intelligent pulmonary function instrument. Background Technology

[0002] A pulmonary function testing device is a medical device used to measure the volume of air inhaled and exhaled by the lungs. It can perform pulmonary function tests and track lung health. Pulmonary function testing devices are divided into handheld and non-handheld types. Handheld pulmonary function testing devices are used to detect the patient's respiratory function status and can help detect respiratory diseases in their early stages.

[0003] Among them, the handheld smart pulmonary function instrument is convenient to carry, which makes it easy to test the patient's respiratory function. However, the mouthpiece used for testing is not easy to disassemble, making it inconvenient to replace it when used by different patients. Using the same mouthpiece can easily cause cross-infection. Therefore, further improvements can be made. Utility Model Content

[0005] As an optimization, the connecting assembly includes a mounting ring fixedly installed inside the front port of the connecting cylinder, a connecting tube fixedly installed at one end of the back of the bite, an embedded ring fixedly installed at one end of the back of the connecting tube, and the embedded ring is inserted into the mounting ring.

[0006] As an optimization, a support plate is fixedly installed on the outer array of the embedded ring, a slot is opened on one side of the front of the mounting ring corresponding to the support plate, a limiting arc groove is opened inside the mounting ring corresponding to the slot, and a gasket is glued to one side of the front of the support plate.

[0007] As an optimization, a sealing gasket is glued to the inner wall of the mounting ring, and the embedded ring is pressed tightly against its inner wall by the sealing gasket to improve the sealing performance.

[0008] As an optimization, the stabilizing component includes a housing fixedly installed on both sides of the upper half of the instrument body, a slider slidably connected inside the housing, a tension spring fixedly installed between the slider and the top wall of the housing, ear seats fixedly installed on both sides of the bottom of the slider, a pull strap hinged between the ear seats on both sides, and shafts fixedly installed on both sides of the bottom of the instrument body, with the bottom end of the pull strap hinged inside the support.

[0009] As an optimization, both the ear seat and the support are rotatably connected to shafts, and the shafts are respectively rotatably inserted into both ends of the pull strap.

[0010] As an optimization, the pull strap is made of elastic fiber material, which is a blend of rubber and polyester, and has good anti-slip and breathability, and is not easy to curl at the edges.

[0011] The beneficial effects of this utility model are:

[0012] 1. This portable intelligent pulmonary function instrument works by inserting the embedded ring into the mounting ring, aligning the support plate with the slot, pressing it down to lock it into the bottom of the slot, and then turning the connecting tube to make the support plate rotate and embed itself in the limiting arc groove, which can play a limiting role. The gasket tightly abuts against the inner wall of the limiting arc groove, thereby increasing stability through friction. At the same time, the embedded ring will tightly adhere to its inner wall by squeezing the sealing gasket, thereby improving the sealing performance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 A portable intelligent pulmonary function instrument includes an instrument body 1, a connecting cylinder 2 is provided inside the top of the instrument body 1, an eddy current sensor is provided inside the connecting cylinder 2, a mouthpiece 3 is provided at one end of the front of the connecting cylinder 2, a connecting component 4 for easy disassembly and assembly is provided between the connecting cylinder 2 and the mouthpiece 3, a gripping part 5 for easy gripping is provided on both sides of the lower half of the instrument body 1, and a stabilizing component 6 for improving grip stability is provided on both sides of the upper half of the instrument body 1.

[0022] Please see Figure 2 The connecting assembly 4 includes a mounting ring 7 fixedly installed in the front port of the connecting cylinder 2, a connecting tube 8 fixedly installed on one back end of the bite 3, an embedded ring 9 fixedly installed on one back end of the connecting tube 8, and a sealing gasket 14 glued to the inner wall of the mounting ring 7. The embedded ring 9 is tightly fitted to its inner wall by squeezing the sealing gasket 14 to improve the sealing performance.

[0023] Please see Figure 2An embedded ring 9 is inserted into a mounting ring 7. A support plate 10 is fixedly mounted on the outer side of the embedded ring 9. A slot 11 is opened on one side of the front of the mounting ring 7 corresponding to the support plate 10. A limiting arc groove 12 is opened inside the mounting ring 7 corresponding to the slot 11. A gasket 13 is glued to one side of the front of the support plate 10. By aligning the support plate 10 with the slot 11 and pressing it into the bottom of the slot 11, and then turning the connecting pipe 8, the support plate 10 can be rotated and embedded in the limiting arc groove 12, which can play a limiting role. The gasket 13 tightly abuts against the inner wall of the limiting arc groove 12 to improve the sealing performance.

[0024] Please see Figure 3-4 The stabilizing component 6 includes a housing 15 fixedly installed on both sides of the upper half of the instrument body 1. A slider 16 is slidably connected inside the housing 15. A tension spring 17 is fixedly installed between the slider 16 and the top wall of the housing 15. Ear seats 18 are fixedly installed on both sides of the bottom of the slider 16. A pull strap 19 is hinged between the two ear seats 18. The pull strap 19 is made of elastic fiber material, which is made of rubber and polyester blend. It has good anti-slip and breathability and is not easy to curl.

[0025] Please see Figure 3-4 The instrument body 1 has shafts 21 fixedly installed on both sides of its bottom, and the bottom end of the pull strap 19 is hinged to the inside of the support 20. The ear seat 18 and the inside of the support 20 are rotatably connected to the shafts 21, and the shafts 21 are respectively rotatably inserted into the two ends of the pull strap 19. When holding the pulmonary function instrument, the fingers pass through the inside of the pull straps 19 on both sides, which will pull the slider 16 to slide along the inner wall of the outer shell 15, thus stretching the tension spring 17. Through the elastic force of the tension spring 17, the pull strap 19 will be tightened, thereby improving the stability of holding the instrument and preventing accidental drop due to unstable grip.

[0026] When in use, first hold the grip part 5 with your fingers. As your fingers pass through the inside of the pull straps 19 on both sides, the slider 16 will slide along the inner wall of the outer shell 15, which will stretch the tension spring 17. At the same time, the tension spring 17 will tighten the pull straps 19 through its own elasticity, thereby improving the stability of holding the instrument.

[0027] Then, insert the inner ring 9 into the mounting ring 7, align the support plate 10 with the slot 11, and press it down to make it snap into the bottom of the slot 11. Then, turn the connecting pipe 8 to make the support plate 10 rotate and embed into the limiting arc groove 12, which can play a limiting role. The gasket 13 tightly abuts against the inner wall of the limiting arc groove 12, and the stability is increased by friction.

[0028] In summary, this portable intelligent pulmonary function instrument achieves a limiting function by inserting the embedded ring 9 into the mounting ring 7, aligning the support plate 10 with the slot 11, pressing it down to lock it into the bottom of the slot 11, and then twisting the connecting tube 8 to make the support plate 10 rotate and embed into the limiting arc groove 12. Furthermore, the gasket 13 tightly abuts against the inner wall of the limiting arc groove 12, thereby increasing stability through friction. At the same time, the embedded ring 9 tightly adheres to the inner wall of the sealing gasket 14 by squeezing it, thereby improving the sealing performance.

[0029] When holding the instrument, fingers pass through the inside of the pull straps 19 on both sides, which in turn pulls the slider 16 to slide along the inner wall of the outer casing 15, thus stretching the tension spring 17. At the same time, the tension spring 17 itself tightens the pull straps 19, thereby improving the stability of holding the instrument and preventing the instrument from being accidentally dropped due to an unstable grip.
