Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a connection structure for a pulmonary function instrument. Background Technology

[0002] A pulmonary function tester 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. The pulmonary function tester uses a physical examination method that is non-invasive, painless, and comfortable.

[0003] Existing pulmonary function instruments require an external flow sensor for use. Users exhale through the nozzle, and the flow sensor works in conjunction with the pulmonary function instrument to complete the test. However, the connection between the flow sensor and the sensor interface of the pulmonary function instrument is usually secured mechanically by tightening bolts, which prevents quick disassembly and reassembly. Therefore, further improvements are needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a connection structure for a pulmonary function instrument, comprising an instrument body, heat dissipation grooves on both sides of the instrument body for heat dissipation, a power socket and a sensor socket on one side of the back of the instrument body, a plug being inserted into the sensor socket, a connecting wire being fixedly connected to the center of the back of the plug, an air nozzle being fixedly installed at the end of the connecting wire, a flow rate sensor being installed inside the air nozzle, and a connecting component for quick positioning of the plug being provided at the sensor socket.

[0005] As an optimization, the connection assembly includes a mounting shell fixedly installed on one side of the back of the instrument body, and the mounting shell is fitted over the outside of the sensor socket. The connector end of the plug is provided with a sleeve on its outside, and the sleeve is fitted over the outside of the sensor socket. Guide rails are fixedly installed on both sides of the inner wall of the mounting shell, and limit plates are fixedly installed on both sides of the sleeve. The limit plates are slidably inserted into the inside of the guide rails, and the sleeve is inserted into the inside of the mounting shell through the limit plates.

[0006] As an optimization, several sets of elastic elements are provided on both the upper and lower sides of the guide rail, and limit holes are opened on both the upper and lower sides of the limit plate corresponding to the elastic elements. Positioning elements for limit installation are provided in the middle of both the upper and lower sides of the mounting shell, and slots are opened in the middle of both sides of the sleeve corresponding to the positioning elements.

[0007] As an optimization, the limiting plate is T-shaped, and the internal groove of the guide rail is set to correspond to the limiting plate.

[0008] As an optimization, the elastic element includes a fixed cylinder fixedly installed inside the upper and lower sides of the guide rail. A slider is slidably connected inside the fixed cylinder. A ball is embedded inside the slider. A compression spring is fixedly installed between the slider and the inner wall of the fixed cylinder. The ball is driven into the limiting hole by the elasticity of the compression spring itself.

[0009] As an optimization, the positioning component includes a horizontal plate fixedly installed in the middle of the upper and lower sides of the mounting shell. A pressing block is slidably connected inside the horizontal plate. A plug rod is fixedly installed on the opposite side of the pressing block on both sides, and the plug rod is slidably inserted into the center of both ends of the horizontal plate. A plug plate is fixedly installed at the end of the plug rod. A return spring is sleeved on the outside of the plug rod, and the plug plate is inserted into the slot under the elastic force of the return spring. A pressing component for pushing and pulling the plug plate in and out of the slot is provided in the middle of the horizontal plate.

[0010] As an optimization, the pressing component includes a bracket fixedly installed in the middle of the horizontal plate, a slide rod slidably inserted in the middle of the bracket, and an extrusion head fixedly installed at one end of the slide rod in the middle of the horizontal plate, with the two inclined surfaces of the extrusion head abutting one side of the inclined surface of the extrusion block.

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

[0012] 1. The connection structure of this pulmonary function instrument involves inserting the limiting plate into the guide rail during connection. This causes the ball bearings to be squeezed, which in turn compresses the compression spring by the slider. This causes the ball bearings to be engaged in the limiting hole for positioning. Furthermore, the elastic force of the return spring causes the insert plate to be engaged in the slot, further achieving the positioning function. This makes installation easy.

[0013] 2. The connection structure of this pulmonary function instrument allows the compression head to move downward by pressing down the sliding rod, which in turn compresses the compression blocks on both sides. This causes the insertion rod to push the insertion plates on both sides to slide back and forth, thus removing the insertion plates from the slot. At this point, the limiting function is no longer applied, and the plug can be pulled out for easy disassembly. Attached Figure Description

[0020] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] 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.

[0022] Please see Figure 1 A connection structure for a pulmonary function instrument includes an instrument body 1. Both sides of the instrument body 1 are provided with heat dissipation grooves 2 for heat dissipation. A power socket 3 and a sensor socket 4 are respectively provided on one side of the back of the instrument body 1. A plug 5 is plugged into the sensor socket 4. A connecting wire 6 is fixedly connected to the center of the back of the plug 5. An air nozzle 7 is fixedly installed at the end of the connecting wire 6. A flow rate sensor is provided inside the air nozzle 7. A connecting component 8 for quick positioning of the plug 5 is provided at the sensor socket 4.

[0023] Please see Figures 2-3The connecting component 8 includes a mounting shell 9 fixedly installed on one side of the back of the instrument body 1, and the mounting shell 9 is fitted on the outside of the sensing socket 4. The connecting end of the plug 5 is provided with a sleeve 10, and the sleeve 10 is fitted on the outside of the sensing socket 4. Guide rails 11 are fixedly installed on both sides of the inner wall of the mounting shell 9. Limiting plates 12 are fixedly installed on both sides of the sleeve 10. The limiting plates 12 are in the shape of a "T". The internal sliding groove of the guide rail 11 is set to correspond to the limiting plate 12. The limiting plate 12 is slidably inserted into the inside of the guide rail 11. The sleeve 10 is inserted into the inside of the mounting shell 9 through the limiting plate 12.

[0024] Please see Figures 2-3 The guide rail 11 has several sets of elastic elements on both the upper and lower sides. The limit plate 12 has limit holes 13 on the upper and lower sides corresponding to the elastic elements. The mounting shell 9 has positioning elements for limit installation on both the upper and lower sides. The sleeve 10 has slots 14 on both sides corresponding to the positioning elements.

[0025] Please see Figures 2-3 The elastic element includes a fixed cylinder 15 fixedly installed inside the upper and lower sides of the guide rail 11. A slider 16 is slidably connected inside the fixed cylinder 15. A ball 17 is embedded inside the slider 16. A compression spring 18 is fixedly installed between the slider 16 and the inner wall of the fixed cylinder 15. The ball 17 is driven into the limiting hole 13 by the elasticity of the compression spring 18. The plug 5 will drive the limiting plate 12 into the guide rail 11, which will squeeze the ball 17, so that the compression spring 18 is compressed by the slider 16, which will drive the ball 17 into the limiting hole 13, thus playing a limiting role.

[0026] Please see Figures 4-5 The positioning component includes a horizontal plate 19 fixedly installed in the middle of the upper and lower sides of the mounting shell 9. A pressing block 20 is slidably connected inside the horizontal plate 19. A plug rod 21 is fixedly installed on the opposite side of the pressing blocks 20 on both sides. The plug rod 21 is slidably inserted into the center of both ends of the horizontal plate 19. A plug plate 22 is fixedly installed at the end of the plug rod 21. A return spring 23 is sleeved on the outside of the plug rod 21. The plug plate 22 is inserted into the slot 14 under the elastic force of the return spring 23. A pressing component for pushing and pulling the plug plate 22 into and out of the slot 14 is provided in the middle of the horizontal plate 19.

[0027] Please see Figures 4-5 The pressing component includes a bracket 24 fixedly installed in the middle of the horizontal plate 19. A slide rod 25 is slidably inserted into the middle of the bracket 24. A pressing head 26 is fixedly installed at one end of the slide rod 25 located in the middle of the horizontal plate 19. The two inclined surfaces of the pressing head 26 abut against one side of the inclined surface of the pressing block 20. By pressing the slide rod 25, the pressing head 26 can be driven to press the pressing blocks 20 on both sides downward. Therefore, the insert rod 21 will push the insert plates 22 on both sides to slide in opposite directions, thereby moving the insert plates 22 out of the slot 14. At this time, it no longer plays a limiting role, and the plug 5 can be pulled out.

[0028] When in use, first connect the power cord through the power socket 3 to turn on the power, and then insert the plug 5 into the sensor socket 4. At this time, the limiting plate 12 slides along the inside of the guide rail 11 and inserts into the guide rail 11, which will squeeze the ball 17, so that the compression spring 18 is compressed by the slider 16, which will drive the ball 17 to be locked into the limiting hole 13, thus playing a limiting role. At the same time, the insert plates 22 on both sides will be pressed against the outside of the housing 10 and slide until they move to the slot 14. At this time, the insert plates 22 will be locked into the slot 14 under the action of the reset spring 23, further performing installation limiting.

[0029] During disassembly, pressing down on the slide bar 25 will cause the compression head 26 to move downward, which will then compress the compression blocks 20 on both sides. As a result, the insertion rod 21 will push the insertion plates 22 on both sides to slide in opposite directions, thereby moving the insertion plates 22 out of the slot 14. At this point, it no longer serves as a limit, and the plug 5 can be pulled out.

[0030] In summary, the connection structure of this pulmonary function instrument allows for easy installation by inserting the limiting plate 12 into the guide rail 11 during connection, which compresses the ball bearing 17, causing the compression spring 18 to be compressed by the slider 16. This, in turn, causes the ball bearing 17 to be engaged in the limiting hole 13 for positioning. Furthermore, the elastic force of the return spring 23 causes the insert plate 22 to be engaged in the slot 14 for further positioning, thus facilitating installation.

[0031] Pressing down the slide bar 25 will cause the extrusion head 26 to move downward, which will then extrude the extrusion blocks 20 on both sides. This will push the insert plates 22 on both sides to slide in opposite directions via the insert rod 21, thereby moving the insert plates 22 out of the slot 14. At this point, the limiting function is no longer used, and the plug 5 can be pulled out, making it easy to disassemble.
