Description

Technical Field

[0002] Blood pressure monitors, such as electronic non-invasive blood pressure monitors (NIBP), generally include a main unit and a cuff. The main unit contains an inflation pump and a deflation valve to inflate and deflate the cuff.

[0003] In related technologies, the main unit's casing is also equipped with an air pressure balance hole to regulate the internal air pressure when the main unit inflates and deflates the cuff. In actual use, departments such as ICUs need to frequently clean and disinfect various monitoring devices. A common disinfection method is to wipe the casing of the main unit with liquid disinfectant. During this process, the disinfectant may seep into the main unit through the air pressure balance hole, thereby damaging the internal components of the main unit. Summary of the Invention

[0082] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0083] Please refer to Figure 1 and Figure 2 In a first aspect, embodiments of this application provide a physiological parameter monitoring device, including a housing 100, an air path assembly 200, and a first interface assembly 300. The housing 100 has a mounting cavity 111 and a first mounting hole 112, the first mounting hole 112 communicating with both the mounting cavity 111 and the outside of the housing 100. The air path assembly 200 is at least partially disposed within the mounting cavity 111, and includes an air pump 21, a valve body 22, and a first conduit 23, both of which are connected to the first conduit 23. The first interface assembly 300 is at least partially disposed within the first mounting hole 112. The first interface assembly 300 has a first air path 35 and a second air path 36. One end of the second air path 36 communicates with the first conduit 23, and the other end of the second air path 36 is used to connect with a cuff 400, so that the air pump 21 can inflate the cuff 400 and the valve body 22 can deflate the cuff 400. The first air passage 35 is connected to the mounting cavity 111 and the outside of the outer casing 100.

[0084] For example, when the air pump 21 is working, the air pump 21 outputs gas sequentially through the first pipe 23 and the second air passage 36, and the gas outside the housing 100 flows into the mounting cavity 111 through the first air passage 35.

[0085] In other words, when the air pump 21 operates, causing the air pressure in the mounting cavity 111 to decrease, the gas outside the housing 100 can flow into the mounting cavity 111 along the first air passage 35; correspondingly, when the valve body 22 operates, causing the air pressure in the mounting cavity 111 to increase, the gas in the mounting cavity 111 can flow out to the outside of the housing 100 along the first air passage 35, thereby balancing the air pressure inside and outside the mounting cavity 111.

[0086] Therefore, it can be seen that the air pressure in the mounting cavity 111 can be adjusted by the first air passage 35 integrated in the first interface component 300 in this embodiment of the application. Compared with setting a separate air pressure balance hole to adjust the air pressure in the mounting cavity 111, this embodiment of the application reduces the number of independent openings on the housing 100, thereby improving the technical problem that disinfectant may seep into the interior of the housing 100 through the air pressure balance hole when the air pressure balance hole is set independently on the housing 100.

[0087] In some embodiments, the physiological parameter monitoring device may include a physiological parameter processing module 500 for obtaining physiological parameter information based on physiological parameter signals. The physiological parameter processing module 500 may be disposed within the mounting cavity 111.

[0088] For example, the pneumatic circuit assembly 200 may also include a pressure sensor 24, which is installed in the first conduit 23. Therefore, when the user wears the cuff 400, the cuff 400 can be connected to the first conduit 23 via the second pneumatic circuit 36, allowing the pressure sensor 24 to collect the pressure signal within the first conduit 23 as a blood pressure physiological parameter signal. The physiological parameter processing module 500 is electrically connected to the pressure sensor 24 to obtain blood pressure physiological parameter information based on the blood pressure physiological parameter signal collected by the pressure sensor 24, thereby achieving non-invasive blood pressure monitoring for the user.

[0089] In some embodiments, the physiological parameter monitoring device further includes a parameter accessory 600, which is used to collect physiological parameter signals. Therefore, the parameter accessory 600 can be used with the physiological parameter processing module 500 so that the physiological parameter processing module 500 can obtain physiological parameter information based on the physiological parameter signals collected by the parameter accessory 600.

[0090] For example, the physiological parameter monitoring device also includes a second interface component 700, which is disposed within the housing 100 and electrically connected to the physiological parameter processing module 500. A parameter accessory 600 is plugged into the second interface component 700. Furthermore, the second interface component 700 can receive physiological parameter signals collected by the parameter accessory 600 and transmit them to the physiological parameter processing module 500, so that the physiological parameter processing module 500 can obtain physiological parameter information.

[0091] It should be noted that the physiological parameter signals collected by parameter annex 600 may include electrocardiogram physiological parameter signals, body temperature physiological parameter signals, etc., and this application embodiment does not limit them.

[0092] The above is an overall description of the physiological parameter monitoring device of the present application embodiment. The technical solution of the present application embodiment will be further illustrated below with reference to the first interface component 300.

[0093] In some embodiments, the first interface assembly 300 is provided with a plug hole 311 for inserting the cuff 400 into the first interface assembly 300, so that the cuff 400 communicates with the second air passage 36. The first air passage 35 can communicate with the mounting cavity 111 and the outside of the housing 100 via the plug hole 311.

[0094] In other words, both the first air passage 35 and the second air passage 36 are connected to the outside of the outer casing 100 through the insertion hole 311. Therefore, when the outer casing 100 of the physiological parameter monitoring device needs disinfection and cleaning, the cuff 400 can be removed first, and then the first air passage 35 and the second air passage 36 can be sealed simultaneously by sealing the insertion hole 311. Thus, compared to sealing the first air passage 35 and the second air passage 36 independently, the embodiments of this application have the advantage of facilitating disinfection and cleaning.

[0095] In some embodiments, the physiological parameter monitoring device further includes a first resilient seal 800. A parameter accessory 600 is at least partially disposed outside the housing 100, and at least one of the parameter accessory 600 and the housing 100 is provided with the first resilient seal 800 for sealing the insertion hole 311.

[0096] For example, the first elastic seal 800 can be fixed to the parameter accessory 600 by a first flexible connector such as a strap, or the first elastic seal 800 can be fixed to the outer shell 100 by a second flexible connector such as a strap. This application embodiment does not limit this.

[0097] The first elastic seal 800 may include any type of elastic seal such as a rubber plug or a silicone plug, and this application embodiment does not limit this.

[0098] In some embodiments, the first interface assembly 300 includes a second conduit 321 and a second resilient seal 322. The second conduit 321 includes a first end 3211 and a second end 3212 disposed opposite each other, forming at least a partial second air passage 36 between the first end 3211 and the second end 3212. The first end 3211 communicates with the first conduit 23. The second resilient seal 322 is mounted on the second end 3212 such that the second end 3212 can communicate with and form a seal with the cuff 400 via the second resilient seal 322.

[0099] For example, the air nozzle 41 of the cuff 400 can be inserted into the insertion hole 311 and abut against the second elastic seal 322, so that the second elastic seal 322 is sandwiched between the second end 3212 and the air nozzle 41, thereby preventing air leakage at the connection between the second air passage 36 and the cuff 400, and improving the accuracy of the physiological parameter monitoring device when detecting blood pressure through the air passage assembly 200.

[0100] For example, the second elastic seal 322 includes a first bottom wall 3221, which abuts against the end face of the second end 3212. The first bottom wall 3221 is provided with a vent hole 3222 communicating with the second end 3212, so that the cuff 400 (such as the air nozzle 41 of the cuff 400) can abut against the first bottom wall 3221 and communicate with the second end 3212 through the vent hole 3222.

[0101] The second elastic seal 322 can be any type of elastic seal, such as a rubber part or a silicone part, and this application embodiment does not limit it.

[0102] In some embodiments, the first interface assembly 300 may include a sleeve 31 and an adapter 32. The sleeve 31 is at least partially disposed within the first mounting hole 112. The adapter 32 is at least partially disposed within the sleeve 31, forming at least a partial first air passage 35 between the adapter 32 and the sleeve 31, and a second air passage 36 is provided within the adapter 32. Therefore, by using a sleeve 31 to cover the adapter 32, the second air passage 36 and the first air passage 35 can be formed on the inside and outside of the adapter 32, respectively, thus simplifying the manufacturing of the first air passage 35 and the second air passage 36.

[0103] The adapter 32 may include the second conduit 321 and the second resilient seal 322 described above. The second conduit 321 is at least partially disposed within the sleeve 31.

[0104] For example, the sleeve 31 may include a first sidewall 312 and a first top wall 313. The first sidewall 312 surrounds the second end 3212 and the outer periphery of the second resilient seal 322. The first top wall 313 is connected to the first sidewall 312 and is located on the side of the second resilient seal 322 facing the outside of the housing 100. The first top wall 313 is provided with an insertion hole 311, which communicates with the outside of the housing 100, so that the cuff 400 can be inserted into it to abut against the second resilient seal 322 to form a seal.

[0105] Therefore, the sleeve 31 can not only be used to form the first air passage 35 together with the adapter 32, but also can be reused to restrict the second elastic seal 322 on the second end 3212 of the second pipe 321, so as to realize the installation and fixation of the second elastic seal 322, thereby making the structure and assembly of the first interface assembly 300 simpler.

[0106] For example, during the assembly process: First, the second elastic seal 322 can be inserted into the sleeve 31 from the end of the sleeve 31 away from the first top wall 313; then, the second pipe 321 can be inserted into the sleeve 31 from the end of the sleeve 31 away from the first top wall 313, so that the second elastic seal 322 is sandwiched between the first top wall 313 and the second pipe 321.

[0107] Please continue to refer to this. Figure 3 and Figure 4In some embodiments, the first interface assembly 300 further includes a bracket 33 and a limiting member 34. The bracket 33 is disposed between the first top wall 313 and the first bottom wall 3221. The bracket 33 includes a second side wall 331 surrounding the insertion hole 311 and the vent hole 3222. The second side wall 331 is provided with a second mounting hole 332. The limiting member 34 passes through the second mounting hole 332 and protrudes partially from the inner surface of the second side wall 331.

[0108] Continuing with the example of inserting the air nozzle 41 of the cuff 400 into the insertion hole 311, the air nozzle 41 can be inserted into the inner side of the second side wall 331 to abut against the second elastic seal 322. At this time, the peripheral surface of the air nozzle 41 can come into contact with the limiting member 34 and thus be fixed by the limiting member 34.

[0109] For example, the peripheral surface of the air nozzle 41 may be provided with a limiting groove 411. When the air nozzle 41 abuts against the first bottom wall 3221, the limiting member 34 is engaged with the limiting groove 411 of the air nozzle 41 to prevent the air nozzle 41 of the cuff 400 from falling off.

[0110] In some embodiments, the limiting member 34 can be movably disposed in the second mounting hole 332, so that the limiting member 34 can move toward the inside of the second sidewall 331 to engage and fix it in the limiting groove 411 to prevent the nozzle 41 from disengaging, and the limiting member 34 can move toward the outside of the second sidewall 331 to disengage from the limiting groove 411 to allow the nozzle 41 to fall off.

[0111] In some embodiments, the second resilient seal 322 may further include a third sidewall 3223 connected to the first bottom wall 3221, the third sidewall 3223 being located on the outer periphery of the second sidewall 331, and the side surface of the third sidewall 3223 facing the second sidewall 331 abutting against the limiting member 34.

[0112] So, during the process of the user inserting the air nozzle 41 of the cuff 400 into the first interface assembly 300: First, the air nozzle 41 can push the limiting member 34 to move outward toward the second side wall 331 to compress the third side wall 3223; then, when the air nozzle 41 abuts against the first bottom wall 3221, the limiting member 34 is directly opposite the limiting groove 411 of the air nozzle 41, at which time the third side wall 3223 elastically recovers, so as to push the limiting member 34 to move inward toward the second side wall 331 and lock into the limiting groove 411.

[0113] Conversely, when the user needs to pull out the air nozzle 41 of the cuff 400, they only need to use greater force so that the peripheral surface of the air nozzle 41 pushes the limiting member 34 to compress the third side wall 3223.

[0114] Therefore, the second elastic seal 322 can also be reused in the embodiment of this application to push the limiting member 34 to engage the air nozzle 41, so that there is no need to set an additional elastic member to push the limiting member 34 to engage the air nozzle 41, thereby making the first interface assembly 300 have the advantages of simple structure and easy installation.

[0115] In some embodiments, the outer surface of the end of the limiting member 34 facing the inner side of the second sidewall 331 can be spherical, so that when the user inserts or removes the air nozzle 41, the limiting member 34 can be driven to move outward of the second sidewall 331 through the spherical surface.

[0116] For example, the limiting member 34 can be spherical. Then, when the user inserts or removes the air nozzle 41, the limiting member 34 can roll within the second mounting hole 332 to form rolling friction with the peripheral surface of the air nozzle 41, so as to facilitate the user's insertion or removal of the air nozzle 41.

[0117] In some embodiments, the inner wall of the second mounting hole 332 may be inclined inward in the direction toward the inner side of the second sidewall 331. Therefore, the second mounting hole 332 is a tapered hole, and the opening at the end of the second mounting hole 332 facing the inner sidewall 331 is smaller. Then, when the third sidewall 3223 elastically recovers, it can be pushed along the wall of the second mounting hole 332 until it precisely engages with the limiting groove 411.

[0118] The number of second limiting members 34 can be one or more, such as two, three, four, or five, and this application embodiment does not limit this. When there are multiple second limiting members 34, more second limiting members 34 can be engaged with the limiting groove 411 to improve the stability of the air nozzle 41 insertion.

[0119] In some embodiments, at least some of the second limiting members 34 are evenly spaced along the circumference of the second sidewall 331 so that the force is more even when the air nozzle 41 is engaged with the first interface assembly 300.

[0120] In some embodiments, the third sidewall 3223 may be an annular wall and may be disposed around the second sidewall 331. Thus, a plurality of second limiting members 34 may abut at different positions in the circumferential direction of the third sidewall 3223.

[0121] In some embodiments, a second air passage 36 may be formed by the insertion hole 311, the second sidewall 331 of the bracket 33, and the second conduit 321.

[0122] As mentioned above, at least a portion of the first air passage 35 can be formed between the adapter 32 and the sleeve 31. The first air passage 35 includes a first sub-air passage 351 and a second sub-air passage 352 that are interconnected. The first sub-air passage 351 is formed between the first sidewall 312 and the adapter 32, and the second sub-air passage 352 is formed between the first top wall 313 and the adapter 32 and connects to the outside of the housing 100 via the insertion hole 311. Thus, gas in the mounting cavity 111 can be discharged sequentially through the first sub-air passage 351, the second sub-air passage 352, and the insertion hole 311, or gas outside the housing 100 can flow into the mounting cavity 111 sequentially through the insertion hole 311, the second sub-air passage 352, and the first sub-air passage 351.

[0123] For example, the bracket 33 also includes a second top wall 333 located between the first top wall 313 and the second elastic seal 322, and a second side wall 331 connected to the side of the second top wall 333 facing the first bottom wall 3221.

[0124] Therefore, a first groove 314 may be provided on the side of the first top wall 313 facing the second top wall 333 to form a partial first air passage 35 between the first top wall 313 and the second top wall 333; and / or, a second groove 334 may be provided on the side of the second top wall 333 facing the first top wall 313 to form a partial first air passage 35 between the first top wall 313 and the second top wall 333.

[0125] For example, the second sidewall 331 can abut against the first sidewall 312, and the second sidewall 331 abuts against the first bottom wall 3221, so that the bracket 33 is clamped and fixed between the first top wall 313 of the sleeve 31 and the first bottom wall 3221 of the second elastic seal 322. At this time, the second sub-gas passage 352 is formed by the first groove 314 and / or the second groove 334.

[0126] It is understood that the number of first grooves 314 can be one or more, such as two, three, four, and five, and this application embodiment does not limit this. The number of second grooves 334 can also be one or more, such as two, three, four, and five, and this application embodiment does not limit this.

[0127] In some embodiments, a third groove 335 is provided on the outer periphery of the second top wall 333 to form a partial first air passage 35 between the first side wall 312 and the second top wall 333. Thus, at least a partial first sub-air passage 351 can be formed by the third groove 335.

[0128] It is understood that the number of third grooves 335 can be one or more, such as two, three, four or five, and this application embodiment does not limit this.

[0129] In some embodiments, a fourth groove 3224 is provided on the outer peripheral side of the second resilient seal 322 to form a partial first air passage 35 between the first sidewall 312 and the second resilient seal 322. Thus, at least a partial first sub-air passage 351 can be formed by the fourth groove 3224.

[0130] It is understood that the number of fourth grooves 3224 can be one or more, such as two, three, four or five, and this application embodiment does not limit this.

[0131] In some embodiments, a fifth groove 315 is provided on the inner circumferential side of the first sidewall 312, forming a partial first air passage 35 between the first sidewall 312 and the second elastic seal 322. Thus, at least a partial first sub-air passage 351 can be formed by the fifth groove 315.

[0132] It is understood that the number of fifth grooves 315 can be one or more, such as two, three, four or five, and this application embodiment does not limit this.

[0133] In some embodiments, a fifth groove 315 is provided on the inner circumferential side of the first sidewall 312 to form a partial first air passage 35 between the first sidewall 312 and the second top wall 333. Thus, at least a partial first sub-air passage 351 can be formed by the fifth groove 315.

[0134] For example, a fifth groove 315 may be provided on the inner circumference of the first sidewall 312 to form a portion of the first sub-gas passage 351, and a second groove 334 may be provided on the side of the second top wall 333 facing the first top wall 313 to form a second sub-gas passage 352. Then, the mounting cavity 111 can sequentially communicate with the outside of the outer casing 100 through the fifth groove 315, the second groove 334, and the insertion hole 311.

[0135] Please continue to refer to this. Figure 5 and Figure 6 In some embodiments, the circumferential surface of the second pipe 321 includes a threaded portion 3213 and a venting portion 3214, which are located on different sides of the second pipe 321 in the circumferential direction. The threaded portion 3213 is threadedly connected and fixed to the inner wall of the sleeve 31 (e.g., the first side wall 312). The venting portion 3214 is spaced apart from the inner wall of the sleeve 31 to form a partial first air passage 35 between the venting portion 3214 and the inner wall of the sleeve 31.

[0136] Furthermore, the second pipe 321 can be screwed and fixed to the sleeve 31 through the threaded part 3213, and can also form a partial first air passage 35 between the venting part 3214 and the inner wall of the sleeve 31.

[0137] For example, a partial first sub-air passage 351 is formed between the vent 3214 and the inner wall of the sleeve 31, a partial first sub-air passage 351 is formed by the fifth groove 315, and a second sub-air passage 352 is formed by the second groove 334. Then, the mounting cavity 111 can sequentially pass through the vent 3214, the fifth groove 315, the second groove 334, and the insertion hole 311 to connect to the outside of the outer casing 100.

[0138] It is also understood that the number of ventilation sections 3214 can be one or more, such as two, three, four or five, and this application embodiment does not limit this.

[0139] Therefore, one possible installation process for the adapter 32 and the sleeve 31 is as follows:

[0140] First, the limiting member 34 is inserted into the second mounting hole 332 of the bracket 33 to form a first intermediate member; then, the first intermediate member is inserted into the third side wall 3223 of the second elastic seal 322 to form a second intermediate member; next, the second intermediate member is inserted into the sleeve 31; finally, the second end 3212 of the second pipe 321 is threaded into the sleeve 31 to press and lock the second intermediate member onto the first top wall 313 of the sleeve 31, thereby realizing the adapter 32 and the sleeve 31. It can be seen that the first interface assembly 300 of this embodiment has the advantage of easy assembly.

[0141] In some embodiments, the first interface assembly 300 further includes a third elastic seal 37 disposed between the sleeve 31 and the wall of the first mounting hole 112 to seal the gap between the sleeve 31 and the wall of the first mounting hole 112.

[0142] For example, please continue to refer to Figure 7 A stepped surface can be formed on the inner surface of the first mounting hole 112, and the third elastic seal 37 is placed between the end of the first side wall 312 away from the first top wall 313 and the stepped surface, thereby sealing the gap between the hole wall of the first mounting hole 112 and the sleeve 31. Furthermore, during disinfection and cleaning, liquid can be prevented from seeping in through the gap between the hole wall of the first mounting hole 112 and the sleeve 31.

[0143] In some embodiments, outside the sleeve 31 of the first end 3211 (i.e. the end of the second pipe 321 near the mounting cavity 111), a third air passage 38 is formed between the outer peripheral surface of the first end 3211 and the hole wall of the first mounting hole 112. The third air passage 38 is connected to the first air passage 35 and the mounting cavity 111 respectively.

[0144] For example, the third air passage 38 can be connected to the first sub-air passage 351 at the vent 3214, so that the mounting cavity 111 is connected to the outside of the housing 100 in sequence through the third air passage 38, the first sub-air passage 351, the second sub-air passage 352 and the insertion hole 311.

[0145] It is understood that a gap may be formed between the inner circumferential surface of the third resilient seal 37 and the outer circumferential surface of the adapter 32 (e.g., the second conduit 321 of the adapter 32) to prevent the third resilient seal 37 from isolating the third gas passage 38 from the first sub-gas passage 351.

[0146] Please continue to refer to this. Figure 8 and Figure 9 In some embodiments, the peripheral surface of the first interface assembly 300 is provided with a slot 3215. The first interface assembly 300 also includes a snap-fit ​​member 39, which is mounted on the housing 100 and snaps into the slot 3215.

[0147] In some embodiments, the housing 100 includes a first housing 11 and a second housing 12. The first housing 11 has a mounting cavity 111 and a first mounting hole 112. The second housing 12 is connected to the first housing 11 to close the mounting cavity 111.

[0148] In some embodiments, a slot 113 is further provided through the wall of the first mounting hole 112, and the snap-fit ​​member 39 is inserted into the slot 113 to snap into the slot 3215. The opening of the slot 113 and the opening of the mounting cavity 111 face the same side as the first housing 11. The second housing 12 covers the snap-fit ​​member 39.

[0149] Therefore, taking the sleeve 31 or the second pipe 321 having a groove 3215 on its peripheral surface as an example, one way to install the first interface assembly 300 can be:

[0150] First, the third elastic seal 37 is inserted into the first mounting hole 112 so that the third elastic seal 37 is located at the stepped surface; then, the first interface assembly 300 is inserted into the first mounting hole 112 from the outside of the housing 100 so that the first side wall 312 of the sleeve 31 presses the third elastic seal 37 against the stepped surface; next, the snap-fit ​​39 is inserted from the slot 113 so that the snap-fit ​​39 is snapped and fixed in the slot 3215; finally, the second housing 12 is installed onto the first housing 11.

[0151] Secondly, embodiments of this application also provide a physiological monitoring device, comprising a housing 100, a gas path assembly 200, and a first interface assembly 300. The housing 100 has a mounting cavity 111 and a first mounting hole 112, the first mounting hole 112 communicating with both the mounting cavity 111 and the outside of the housing 100. The gas path assembly 200 is at least partially disposed within the mounting cavity 111, and includes an air pump 21, a valve body 22, and a first conduit 23, both of which are connected to the first conduit 23. The first interface assembly 300 is at least partially disposed within the first mounting hole 112, defining a first gas path 35 and a second gas path 36 within the first mounting hole 112. One end of the second air passage 36 is connected to the first pipe 23, and the other end of the second air passage 36 is used to connect to the cuff 400 so that the air pump 21 can inflate the cuff 400 and the valve body 22 can deflate the cuff 400. The first air passage 35 is connected to the mounting cavity 111 and the outside of the outer shell 100 respectively.

[0152] For example, when the air pump 21 is working, the air pump 21 outputs gas sequentially through the first pipe 23 and the second air passage 36, and the gas outside the housing 100 flows into the mounting cavity 111 through the first air passage 35.

[0153] In other words, when the air pump 21 operates, causing the air pressure in the mounting cavity 111 to decrease, the gas outside the housing 100 can flow into the mounting cavity 111 along the first air passage 35; correspondingly, when the valve body 22 operates, causing the air pressure in the mounting cavity 111 to increase, the gas in the mounting cavity 111 can flow out to the outside of the housing 100 along the first air passage 35, thereby balancing the air pressure inside and outside the mounting cavity 111.

[0154] Therefore, this embodiment of the application integrates the first interface component 300 to define the first air passage 35 and the second air passage 36 within a first mounting hole 112. This not only enables the inflation and deflation of the cuff 400, but also balances the air pressure inside and outside the mounting cavity 111. Compared to setting a separate air pressure balancing hole to adjust the air pressure inside the mounting cavity 111, this embodiment of the application reduces the number of independent openings on the outer shell 100, thereby improving the technical problem that disinfectant may seep into the interior of the outer shell 100 through the air pressure balancing hole when it is set independently on the outer shell 100.

[0155] In some embodiments, at least a portion of the first air passage 35 is formed between the wall of the first mounting hole 112 and the outer surface of the first interface assembly 300; or, at least a portion of the first air passage 35 is formed within the first interface assembly 300.

[0156] In other words, the difference from the physiological monitoring device mentioned above is that, in this embodiment, the first air passage 35 can be formed either inside the first interface component 300 or between the hole wall of the first mounting hole 112 and the outer surface of the first interface component 300. This embodiment does not limit this.

[0157] In some embodiments, the specific structure of the first interface component 300 can be referred to the specific structure of the first interface component 300 described above, and will not be repeated here. It should also be noted that, in the embodiments of this application, at least a portion of the first air passage 35 may be formed between the sleeve 31 and the adapter 32, or at least a portion of the first air passage 35 may not be formed, and the embodiments of this application do not limit this.

[0158] In some embodiments, the specific structures of the housing 100 and the gas passage assembly 200 can be referred to the specific structures of the housing 100 and the gas passage assembly 200 described above, and will not be repeated here in the embodiments of this application.

[0159] In some embodiments, the physiological parameter monitoring device may further include at least one of a physiological parameter processing module 500, a parameter accessory 600, and a first elastic seal 800. The specific structures of the physiological parameter processing module 500, the parameter accessory 600, and the first elastic seal 800 can be referred to the specific structures of the physiological parameter processing module 500, the parameter accessory 600, and the first elastic seal 800 described above, and will not be repeated here in the embodiments of this application.
