Description

Technical Field

[0001] This utility model relates to the field of spirometer technology, specifically a novel spirometer. Background Technology

[0002] A spirometer is an instrument used to measure the size of a person's lung capacity. The user exhales continuously through the mouthpiece and blows air into the instrument through the air inlet tube to measure the volume of air exhaled during the exhalation process.

[0003] Currently, primary and secondary schools in my country measure students' lung capacity every year. When using existing spirometers, the spirometer is placed on a table. Its air intake tube is usually set as a retractable tube. When using it, the retractable tube is placed on the table, and the user takes a disposable mouthpiece, inserts it into the end of the retractable tube, and blows air. After blowing air, the retractable tube is placed back on the table for the next person to use.

[0004] Existing spirometers often lack a secure device when the telescopic tube is placed on the table, making it easy for it to slip off and cause contamination. Therefore, we propose a novel spirometer. Utility Model Content

[0005] The purpose of this invention is to provide a novel spirometer to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel spirometer includes: a base plate on which a spirometer body is placed, and an air inlet of the spirometer body is connected to a telescopic tube for collecting gas; and a housing, an L-shaped support frame, and an adjustment structure. The lower end of the housing is fixed to the base plate, and a cavity is provided inside the housing. The vertical section of the L-shaped support frame extends into the cavity through a notch on the top surface of the housing, and a fixing ring is provided on the horizontal section of the L-shaped support frame, with the distal end of the telescopic tube engaged with the fixing ring. The adjustment structure is located on one side of the housing and is used to adjust the length of the vertical section of the L-shaped support frame extending into the cavity.

[0007] Preferably, the adjustment structure includes: a connecting rod, a gear, and a spring; a rack is provided at one end of the L-shaped support frame that extends into the cavity; one end of the connecting rod extends through the side of the housing into the cavity, and the other end extends outward; one side of the gear meshes with the rack, and the other side is fixed to the end of the connecting rod that extends into the cavity; the spring is sleeved on the outer surface of the connection section between the connecting rod and the gear.

[0008] Preferably, the end of the connecting rod extending to the outside is connected to a pull ring.

[0009] Preferably, the fixing ring is connected to a sealing cap for sealing the opening at the end of the telescopic tube via an anti-loss rope.

[0010] Preferably, it also includes a sleeve, which is fitted onto the middle part of the telescopic tube and is fixed to the base plate by a support post.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this novel spirometer, the distal end of the telescopic tube used for collecting gas is fixed by a fixing ring, which facilitates its placement and prevents the end from slipping off the table and causing contamination during the measurement of spirometer. At the same time, the length of the vertical section of the L-shaped support frame extending into the cavity can be adjusted by the set adjustment structure, thereby adjusting the distance between the distal end of the telescopic tube and the table to adapt to the use of subjects of different ages and heights.

[0014] 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.

[0015] like Figures 1-3As shown, a novel spirometer includes: a base plate 1, on which a spirometer body 2 is placed, and the air inlet of the spirometer body 2 is connected to a telescopic tube 3 for collecting gas; and further includes: a housing 4, an L-shaped support frame 5, and an adjustment structure 6; the lower end of the housing 4 is fixed to the base plate 1, and a cavity 41 is provided inside the housing 4; the vertical section of the L-shaped support frame 5 extends into the cavity 41 through a notch on the top surface of the housing 4, and the horizontal section of the L-shaped support frame 5 is provided with a fixing ring 51, and the distal end of the telescopic tube 3 is engaged with the fixing ring 51; the adjustment structure 6 is provided on one side of the housing 4 and is used to adjust the length of the vertical section of the L-shaped support frame 5 extending into the cavity 41.

[0016] Specifically, compared with traditional spirometers, the spirometer in this embodiment places the base plate 1 on the table, then places the spirometer body 2 on the base plate 1, and fixes the distal end of the telescopic tube 3 for collecting gas with a fixing ring 51, which facilitates its placement and prevents its end from slipping off the table and causing contamination during the measurement of spirometer capacity. At the same time, the length of the vertical section of the L-shaped support frame 5 extending into the cavity 41 can be adjusted by the adjustment structure 6, thereby adjusting the distance between the distal end of the telescopic tube 3 and the table to accommodate the use of subjects of different ages and heights.

[0017] Preferably, in this embodiment, the fixing ring 51 is a complete circular ring, and its inner diameter is slightly smaller than the outer diameter of the telescopic tube 3. In use, the distal end of the telescopic tube 3 is inserted into the inner ring of the fixing ring 51 to achieve a snap-fit ​​fixation. In another embodiment, the fixing ring 51 can be set to a shape larger than a semi-circular ring, or it can be understood as having a notch on the basis of a circular ring structure, and the inner diameter of the fixing ring 51 is slightly smaller than the outer diameter of the telescopic tube 3. When snapping, the distal end of the telescopic tube 3 is snapped into the inner ring of the fixing ring 51 through the notch.

[0018] Furthermore, the adjustment structure 6 includes: a connecting rod 61, a gear 62, and a spring 63; a rack 52 is provided at one end of the L-shaped support frame 5 that extends into the cavity 41; one end of the connecting rod 61 extends through the side of the housing 4 into the cavity 41, and the other end extends outward; one side of the gear 62 meshes with the rack 52, and the other side is fixed to the end of the connecting rod 61 that extends into the cavity 41; the spring 63 is sleeved on the outer surface of the connection section between the connecting rod 61 and the gear 62.

[0019] Specifically, during the process of adjusting the length of the vertical section of the L-shaped support frame 5 extending into the cavity 41, the user pulls the end of the connecting rod 61 that extends to the outside with one hand, so that the gear 62 and the rack 52 are separated. With the other hand, the user holds the upper end of the L-shaped support frame 5 and pulls the L-shaped support frame 5 up and down to adjust it to a suitable height. After adjustment, the user releases the connecting rod 61. Under the elastic action of the spring 63, the connecting rod 61 engages its gear 62 with the rack 52. In this way, the length of the vertical section of the L-shaped support frame 5 extending into the cavity 41 can be adjusted, and the distance between the distal end of the telescopic tube 3 and the table can be adjusted to accommodate the use of subjects of different ages and heights.

[0020] Preferably, the internal space of the cavity 41 in this embodiment can accommodate the displacement of the compression spring 63 during the pulling of the connecting rod 61, so that the gear 62 and the rack 52 are separated. When the connecting rod 61 is released, the gear 62 can be held against the rack 52 again under the elastic action to achieve a re-engagement state.

[0021] Preferably, in this embodiment, the lower end of the L-shaped support frame 5 has a rectangular cross-section. Therefore, a rectangular notch adapted to the rectangular cross-section is provided on the top surface of the housing 4, so that the rectangular notch communicates with the cavity 41, thereby allowing the lower end of the L-shaped support frame 5 to be inserted into the cavity 41 through the rectangular notch. The insertion depth of the L-shaped support frame 5 can change the height of its upper fixing ring 51 from the bottom plate 1, thereby adjusting the distance between the far end of the telescopic tube 3 and the tabletop.

[0022] Furthermore, a pull ring 64 is connected to the end of the connecting rod 61 that extends to the outside. The pull ring 64 allows users to easily pull the connecting rod 61.

[0023] Furthermore, a sealing cap 7 for sealing the end opening of the telescopic tube 3 is connected to the fixing ring 51 via an anti-loss rope. The anti-loss rope prevents the sealing cap 7 from being lost, and the sealing cap 7 can seal the end opening of the telescopic tube 3, further preventing the telescopic tube 3 from being contaminated.

[0024] Furthermore, it also includes a sleeve 8, which is sleeved on the middle part of the telescopic tube 3, and the sleeve 8 is fixed to the base plate 1 by a support post 9.

[0025] Specifically, the sleeve 8 and the support 9 are designed to support the connection between the telescopic tube 3 and the spirometer body 2, preventing the telescopic tube from falling off.
