DETAILED DESCRIPTION

[0024] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 5 As shown, a nasal resistance measuring instrument comprises: a base plate 1, a rotating assembly and a clamping plate 12,

[0026] Two groups of support plates 2 are fixedly connected to the top of the bottom plate 1, and a limiting groove 4 is provided at the side end of one group of support plates 2, and a support pad 8 is fixedly connected to the inner wall of the side end of the bottom plate 1 away from the support plate 2, and a slide groove 5 is provided inside the support plate 2. When the bottom plate 1 is placed on the table, compared with the traditional method where the patient needs to sit upright to ensure that the head does not move, the patient can place the lower jaw on the support pad 8, and the support pad 8 has the effect of protecting the patient's skin, and the support plate 2 has a supporting function;

[0027] There are two groups of rotating components, which are slidably connected in the slide groove 5. The side ends of the two groups of rotating components are respectively fixedly connected with a baffle 10 and a driving machine 14. The rotating components slide in the slide groove 5 to achieve height adjustment of the rotating components. The rotating components have the function of rotation adjustment.

[0028] Two groups of clamping plates 12 are provided, and the clamping plates 12 are fixedly connected to the rotating assembly, and the rotating assembly can perform rotational adjustment on the clamping plates 12 .

[0029] In some specific embodiments, the rotating assembly includes: a slide 9, a rotating shaft 11 and a rotating plate 16. The slide 9 is slidably connected in the slide groove 5. A rotating groove 15 is opened in the slide 9. The rotating shaft 11 is rotatably connected in the rotating groove 15. The rotating shaft 11 is fixedly connected to the rotating plate 16 in a direction parallel to the inner edge of the rotating groove 15. The rotating shaft 11 is fixedly connected to the rotating plate 16 at the side end close to the limiting groove 4, and the rotating shaft 11 is fixedly connected to the baffle 10 at the side end away from the limiting groove 4. The two groups of rotating shafts 11 are fixedly connected to the clamping plates 12 on opposite sides. The slide 9 drives the rotating shaft 11 and the rotating plate 16 to move up and down. When the driving motor 14 is running, the driving motor 14 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the rotating plate 16 to rotate. At the same time, the rotating shaft 11 drives the clamping plate 12 to rotate, and the baffle 10 limits the other group of rotating shafts 11 to enhance the stability of the rotating shaft 11. Among them, the driving motor 14 has braking properties and belongs to the driving device of the prior art.

[0030] In some specific embodiments, the rotating plate 16 is rotatably connected in the rotating groove 15, and the rotating groove 15 plays a role of limiting support for the rotating plate 16. The rotating plate 16 transmits these effects to the rotating shaft 11 to prevent the rotating shaft 11 from deflecting when rotating.

[0031] In some specific implementation schemes, the driving machine 14 is fixedly connected to the limiting plates 20 on both sides of the side ends close to the slide seat 9. The limiting plates 20 are slidably connected to the limiting grooves 4. The limiting grooves 4 provide limiting effects on the limiting plates 20. The limiting plates 20 transfer the limiting effects to the driving machine 14, thereby preventing the driving machine 14 from self-rotating during driving, thereby ensuring the stability of the structure.

[0032] In some specific embodiments, two groups of threaded rods 21 are rotatably connected in the slide groove 5, and adjustment holes 19 that completely penetrate the slide seat 9 are respectively opened at both ends of the slide seat 9. The adjustment holes 19 are threadedly connected to the threaded rods 21. The rotation of the threaded rods 21 drives the slide seat 9 to move up and down. At the same time, the threaded rods 21 and the adjustment holes 19 are threadedly connected to provide a fixing effect on the slide seat 9.

[0033] In some specific embodiments, the splint 12 is provided with a plurality of positioning holes 18 that penetrate the splint 12 in a direction parallel to the horizontal plane of the base plate 1. The inner wall of the splint 12 is clamped and connected with a nasal resistance handpiece 6. The side end of the splint 12 is fixedly connected with a semi-cylinder 13. The nasal resistance handpiece 6 is fixedly connected with a ring 7 on the side surface close to the splint 12. The ring 7 is abutted and connected with the splint 12. The side end of the ring 7 close to the splint 12 is fixedly connected with a plurality of positioning columns 17. The positioning columns 17 are slidably connected with the positioning holes 18. The nasal resistance handpiece 6 is installed on the side surface of the splint 12. On the splint 12, the ring 7 on the nasal resistance handpiece 6 and the splint 12 are held together, the positioning column 17 on the ring 7 is inserted into the positioning hole 18, and the semi-cylinder 13 prevents scratches on the nasal resistance handpiece 6. The splint 12 prevents the staff from using both hands to operate the nasal resistance handpiece 6 by clamping the nasal resistance handpiece 6, ensuring that the nasal resistance handpiece 6 will not shake during measurement. The limiting effect provided by the positioning hole 18 is transmitted to the nasal resistance handpiece 6 through the positioning column 17, preventing the nasal resistance handpiece 6 from rotating during measurement.

[0034] In order for those skilled in the art to better understand the working principle of the embodiments of the present invention, the following is an explanation in conjunction with specific application scenarios:

[0035] The base plate 1 is placed on the table. Compared with the traditional method in which the patient needs to sit upright to keep the head still, the patient can place the lower jaw on the support pad 8. The support pad 8 supports the patient's head and protects the patient's skin. The support plate 2 has a supporting function. The nasal resistance handpiece 6 is installed on the splint 12. The ring 7 on the nasal resistance handpiece 6 and the splint 12 are held together. The positioning column 17 on the ring 7 is inserted into the positioning hole 18. The splint 12 clamps the nasal resistance handpiece 6 to avoid the staff using both hands to operate it, thereby ensuring that the nasal resistance handpiece 6 does not shake during measurement. The limiting effect provided by the positioning hole 18 is transmitted to the nasal resistance handpiece 6 through the positioning column 17, thereby avoiding the nasal resistance handpiece 6 from rotating during measurement.

[0036] At the same time, the applicability of the nasal resistance handheld device 6 can be improved by adjusting the splint 12. The threaded rod 21 rotates to drive the slide 9 to move up and down. At the same time, the threaded rod 21 and the adjustment hole 19 are threadedly connected to provide a fixing effect on the slide 9. The slide 9 drives the rotating shaft 11 and the rotating plate 16 to move up and down, wherein the limit plate 20 slides on the limit groove 4, and the limit groove 4 provides a limiting effect on the limit plate 20. The limit plate 20 transmits the limiting effect to the driving machine 14 to avoid the driving machine 14 from rotating when driving, thereby ensuring the stability of the structure, thereby driving the splint 12 to adjust the height, and then, the angle of the splint 12 is adjusted through the rotating assembly. When the driving machine 14 is running, the driving machine 14 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the rotating plate 16 to rotate. At the same time, the rotating shaft 11 drives the splint 12 to rotate, and the baffle 10 limits another group of rotating shafts 11 to enhance the stability of the rotating shaft 11, wherein the driving machine 14 has braking properties.

[0037] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
