[0038] Please continue reading Figure 2 and Figure 3 The present application provides a first embodiment of an anti-mistaken touch mechanism 10. The anti-mistaken touch mechanism 10 includes a mounting frame 20, a baffle 30 and an elastic member 40. The baffle 30 and the elastic member 40 are both connected to the mounting frame 20. The elastic member 40 can be a tension spring or a compression spring.

[0039] Please refer to Figure 2 , Figure 4 and Figure 5 , Figure 4 for Figure 2 A schematic structural diagram of a mounting frame 20 of a first embodiment of the anti-mistake-touch mechanism 10 is shown; Figure 5 for Figure 4Schematic diagram of the structure of the mounting frame 20 from another angle. In this embodiment, the mounting frame 20 is provided with a limit groove 21. The limit groove 21 includes an inner wall. The inner wall of the limit groove 21 is provided with an opening 22. The opening 22 penetrates the inner wall, and the opening 22 is configured to expose the functional part 90. A guide member 23 is provided in the limit groove 21. The guide member 23 is configured to limit the sliding path of the baffle 30.

[0040] The inner wall of the limiting groove 21 includes a groove bottom wall 211 and a groove peripheral wall 212 arranged around the edge of the groove bottom wall 211. The opening 22 can be arranged on the groove bottom wall 211 or on the groove peripheral wall 212. The guide member 23 can be arranged on the groove bottom wall 211 or on the groove peripheral wall 212. The guide member 23 can be a slide rail or a slide groove, or can be part of the groove peripheral wall 212.

[0041] Specifically, in this embodiment, the limiting groove 21 is a rectangular groove. The groove peripheral wall 212 includes two limiting walls 2121 and a mounting wall 2122 arranged opposite to each other. The mounting wall 2122 is connected between the two limiting walls 2121 arranged opposite to each other. The opening 22 is arranged on the groove bottom wall 211. The opening 22 passes through the groove bottom wall 211. The guide member 23 can be arranged on the two limiting walls 2121. The guide member 23 can also be arranged on the groove bottom wall 211. The guide member 23 can also be two limiting walls 2121 arranged opposite to each other.

[0042] In other embodiments, the limiting groove 21 may also be a groove of other shapes. Exemplarily, the limiting groove 21 is in a circular or triangular shape. The opening 22 is provided on the groove bottom wall 211, and the opening 22 passes through the groove bottom wall 211. The guide member 23 may be provided on the groove bottom wall 211.

[0043] An abutment portion (not shown) may also be provided in the limiting groove 21. The abutment portion is configured to block the sliding of the blocking piece 30. The abutment portion may be provided on the groove bottom wall 211, the mounting wall 2122 or any limiting wall 2121. Exemplarily, the abutment portion is a limiting block or a limiting plate.

[0044] See also Figure 6 , Figure 6 for Figure 2The structural schematic diagram of the baffle 30 of the first embodiment of the anti-mistouch mechanism 10 is shown. In this embodiment, the baffle 30 includes a sliding surface 31 and a convex surface 32. Along the thickness direction of the baffle 30, the sliding surface 31 and the convex surface 32 are arranged back to back. The baffle 30 includes two side surfaces 33 arranged back to back. Both side surfaces 33 are connected between the sliding surface 31 and the convex surface 32. The baffle 30 can be provided with a paddle 34. The paddle 34 is convexly arranged on the convex surface 32 and extends in a direction away from the convex surface 32. There is an angle between the paddle 34 and the convex surface 32. The baffle 30 can also be provided with a sliding member 35. The sliding member 35 can be a slide groove or a slide rail. The sliding member 35 can be arranged on the two side surfaces 33, and can also be arranged on the sliding surface 31. In other embodiments, the baffle 30 may not be provided with a paddle 34.

[0045] Please continue reading Figure 2 and Figure 3 , the baffle 30 is located in the limiting groove 21, and the sliding member 35 of the baffle 30 is slidably connected to the guide member 23 in the limiting groove 21. The functional member 90 is opposite to the opening 22 of the limiting groove 21. The functional member 90 is located on the side of the groove bottom wall 211 of the limiting groove 21 facing away from the baffle 30. The baffle 30 is configured to cover or expose the functional member 90. One end of the elastic member 40 is connected to the inner wall of the limiting groove 21, and the other end of the elastic member 40 is connected to the baffle 30. Specifically, in this embodiment, one end of the elastic member 40 connected to the inner wall of the limiting groove 21 is specifically connected to the mounting wall 2122 of the limiting groove 21. The elastic member 40 is configured to reset the baffle 30. The extension direction of the elastic member 40 is parallel to the extension direction of the guide member 23. The number of the elastic members 40 can be one or more. This application does not make specific restrictions on this. Exemplarily, the number of the elastic members 40 is two, and the two elastic members 40 are arranged at intervals. The extending directions of the two elastic members 40 are parallel.

[0046] When an abutment portion is provided in the limiting groove 21, the abutment portion is located on the sliding path of the blocking piece 30. Along the extending direction of the guide member 23, the distance between the abutment portion and the edge of the opening 22 close to the abutment portion is greater than the size of the blocking piece 30. It can be understood that when the blocking piece 30 slides to the abutment portion, the opening 22 can be completely exposed.

[0047] In a possible embodiment, the guide member 23 in the limiting groove 21 is disposed on two limiting walls 2121. Exemplarily, the guide member 23 in the limiting groove 21 is a slide rail disposed on the two limiting walls 2121, the sliding member 35 of the baffle 30 is a slide groove disposed on the two side surfaces 33, and the two slide grooves of the baffle 30 are respectively slidably connected to the slide rails of the two limiting walls 2121; or, the guide member 23 in the limiting groove 21 is a slide rail disposed on the two limiting walls 2121, the sliding member 35 of the baffle 30 is a slide groove disposed on the two side surfaces 33, and the two slide grooves of the baffle 30 are respectively slidably connected to the slide rails of the two limiting walls 2121.

[0048] In another possible implementation, the guide member 23 in the limiting groove 21 is two limiting walls 2121. The sliding member 35 of the blocking piece 30 is two side surfaces 33 of the blocking piece 30. The two side surfaces 33 of the blocking piece 30 can slide along the two limiting walls 2121 of the limiting groove 21 respectively.

[0049] In another possible embodiment, the guide member 23 in the limiting groove 21 is disposed on the groove bottom wall 211. Exemplarily, the guide member 23 in the limiting groove 21 is a slide rail disposed on the groove bottom wall 211, the sliding member 35 of the baffle 30 is a slide groove disposed on the sliding surface 31, and the slide groove of the baffle 30 is slidably connected to the slide rail of the groove bottom wall 211; or, the guide member 23 in the limiting groove 21 is a slide groove disposed on the groove bottom wall 211, the sliding member 35 of the baffle 30 is a slide rail disposed on the sliding surface 31, and the slide rail of the baffle 30 is slidably connected to the slide groove of the groove bottom wall 211.

[0050] In one example, the elastic member 40 is a tension spring, which applies tension to the baffle 30, so that the baffle 30 moves away from the mounting wall 2122 along the extension direction of the elastic member 40, so that the functional member 90 can be exposed through the opening 22. At this time, the functional member 90 can be operated. The tension on the baffle 30 is canceled, and under the elastic force of the elastic member 40, the baffle 30 can be reset and moved to the opening 22, thereby covering the functional member 90.

[0051] In another example, the elastic member 40 is a compression spring, which applies pressure to the baffle 30, so that the baffle 30 is close to the mounting wall 2122 along the extension direction of the elastic member 40, so that the functional member 90 can be exposed through the opening 22. At this time, the functional member 90 can be operated. The pressure on the baffle 30 is canceled, and under the elastic force of the elastic member 40, the baffle 30 can be reset and moved to the opening 22, thereby covering the functional member 90.

[0052] It should be noted that when the elastic member 40 is a compression spring, after the blocking piece 30 is reset and moved to the opening 22 , the elastic member 40 may be in an elastic recovery state or may still be in an elastic compression state.

[0053] It can be understood that in this embodiment, an anti-mistaken touch mechanism 10 is provided for the functional part 90 of the anesthesia machine 100, so that the baffle 30 of the anti-mistaken touch mechanism 10 can slide relative to the functional part 90, thereby enabling the baffle 30 to cover or expose the functional part 90. When the functional part 90 needs to be operated, the baffle 30 is slid to expose the functional part 90; when the functional part 90 does not need to be operated, the baffle 30 can cover the functional part 90 to prevent the functional part 90 from being accidentally touched. Therefore, the provision of the anti-mistaken touch mechanism 10 can prevent the functional part 90 of the anesthesia machine 100 from being accidentally touched, thereby preventing the function or state of the anesthesia machine 100 from being accidentally switched, which is conducive to improving the working stability of the anesthesia machine 100.

[0054] In addition, the baffle 30 is connected to the mounting frame 20 through the elastic member 40. When the functional part 90 is exposed by sliding the baffle 30 and the functional part 90 is operated, the elasticity of the elastic member 40 can be used to reset the baffle 30, so that the baffle 30 can cover the functional part 90 again. Therefore, the operational convenience of the anti-mistaken touch mechanism 10 can be improved, and the need to manually move the baffle 30 to reset the baffle 30 is avoided, thereby avoiding the function part 90 being accidentally touched after the baffle 30 is manually forgotten to be closed. Therefore, by connecting the baffle 30 to the mounting frame 20 through the elastic member 40 and resetting the baffle 30 by the elastic member 40, the reliability of the anti-mistaken touch mechanism 10 can be further improved, thereby improving the working stability of the anesthesia machine 100.

[0055] When there are two elastic members 40, the two elastic members 40 are simultaneously connected between the inner wall of the limiting groove 21 and the baffle 30. The baffle 30 can be simultaneously pushed by the two elastic members 40 during the resetting process, thereby improving the sliding smoothness of the baffle 30 in the limiting groove 21; avoiding uneven thrust on the baffle 30, affecting the sliding smoothness of the baffle 30 in the limiting groove 21, and even increasing the degree of wear of the baffle 30 or the guide member 23.

[0056] Please continue reading Figure 1 In this embodiment, the anesthesia machine 100 may further include an anesthesia machine main unit 50 and a breathing circuit 60. The anesthesia machine main unit 50 and the breathing circuit 60 are detachably connected. The functional component 90 is specifically configured to unlock the anesthesia machine main unit 50 and the breathing circuit 60. The above-mentioned functional component 90 and the anti-mistouch mechanism 10 may both be connected to the anesthesia machine main unit 50, or may both be connected to the breathing circuit 60. Specifically, when the breathing circuit 60 is in a connected state with the anesthesia machine main unit 50, the breathing circuit 60 can be unlocked and separated from the anesthesia machine main unit 50 by pressing the functional component 90.

[0057] It can be understood that the functional part 90 is configured to unlock the anesthesia machine main unit 50 and the breathing circuit 60. By providing an anti-mistouch mechanism 10, the stable working state of the anesthesia machine 100 can be ensured; it is prevented that after the functional part 90 is accidentally touched, the anesthesia machine main unit 50 and the breathing circuit 60 are separated, affecting the normal operation of the anesthesia machine 100.

[0058] The anesthesia machine 100 may further include a housing 70. Specifically, in this embodiment, the housing 70 is provided with a through-hole 71. The through-hole 71 is configured to expose the paddle 34 of the baffle 30.

[0059] The main body 50 of the anesthesia machine and the breathing circuit 60 are located on the same side of the cover 70. The cover 70 at least covers the connection between the main body 50 of the anesthesia machine and the breathing circuit 60. In this embodiment, the through-hole 71 of the cover 70 is opposite to the limit groove 21 of the anti-mistaken touch mechanism 10. The paddle 34 of the baffle 30 extends out of the through-hole 71. By moving the paddle 34 in the through-hole 71, the baffle 30 can be driven to move in the limit groove 21, so that the baffle 30 covers or exposes the functional part 90.

[0060] It is understandable that by providing the cover 70 and making the cover 70 at least cover the connection between the anesthesia machine mainframe 50 and the breathing circuit 60, the cover 70 can shield the connection between the anesthesia machine mainframe 50 and the breathing circuit 60, and prevent the connection between the anesthesia machine mainframe 50 and the breathing circuit 60 from being interrupted after the connection between the anesthesia machine mainframe 50 and the breathing circuit 60 is damaged. The through-port 71 of the cover 70 is opposite to the limit groove 21 of the anti-mistaken touch mechanism 10, and the paddle 34 of the baffle 30 extends out of the through-port 71. On the basis of ensuring that the paddle 34 drives the baffle 30 to slide, the cover 70 can also shield the elastic member 40, thereby improving the working reliability of the anti-mistaken touch mechanism 10.

[0061] Please refer to Figure 7 and Figure 8 , Figure 7 for Figure 1 The structure diagram of the second embodiment of the anti-accidental touch mechanism 10 of the anesthesia machine 100 is shown, and the anti-accidental touch mechanism 10 is in the open state at this time; Figure 8 for Figure 7 The second embodiment of the anti-mistaken touch mechanism 10 is shown in a schematic diagram of the structure in a reset state. The present application provides a second embodiment of the anti-mistaken touch mechanism 10. The second embodiment is distinguished from the first embodiment in that the mounting frame 20 is further provided with a positioning groove 24. The elastic member 40 is connected to the inner wall of the positioning groove 24.

[0062] It should be noted that, in this embodiment, the specific implementations of the elastic member 40 , the guide member 23 and the baffle 30 may all refer to the specific implementations of the elastic member 40 , the guide member 23 and the baffle 30 in the first embodiment described above.

[0063] Please refer to Fig. 9 and Fig.10 , Fig. 9 for Figure 7 A schematic structural diagram of a mounting frame of a second embodiment of the anti-mistouch mechanism shown; Fig.10 for Fig. 9The mounting frame 20 is shown in another structural schematic diagram from another angle. The mounting frame 20 may also be provided with a positioning groove 24. The positioning groove 24 has an inner wall. The dimension of the positioning groove 24 along the direction perpendicular to the extension of the guide member 23 is smaller than the dimension of the limiting groove 21 along the direction perpendicular to the extension of the guide member 23. The inner wall of the positioning groove 24 includes a positioning bottom wall 241 and a positioning peripheral wall 242 arranged around the edge of the positioning bottom wall 241.

[0064] The positioning groove 24 is disposed adjacent to the limiting groove 21. The inner wall of the limiting groove 21 is provided with a through hole 25. The through hole 25 conducts the positioning groove 24 and the limiting groove 21.

[0065] Specifically, in the present embodiment, the positioning peripheral wall 242 is a rectangular groove. The positioning peripheral wall 242 includes two positioning walls 2421 arranged opposite to each other and a connecting wall 2422 connected between the two positioning walls 2421. Along the extending direction perpendicular to the guide member 23, the distance between the two positioning walls 2421 is smaller than the distance between the two limiting walls 2121. The mounting wall 2122 of the limiting groove 21 is provided with a through hole 25, and the mounting wall 2122 forms an abutment portion in the limiting groove 21. Along the extending direction of the guide member 23, the distance between the mounting wall 2122 and the edge of the opening 22 close to the mounting wall 2122 is greater than the size of the baffle 30. The positioning groove 24 and the limiting groove 21 are connected to each other through the through hole 25.

[0066] In other embodiments, the positioning groove 24 may also be a groove of other shapes. For example, the positioning groove 24 is in a circular or triangular shape.

[0067] A limiting column 26 may be further provided in the positioning groove 24. The limiting column 26 is configured to position the elastic member 40. The limiting column 26 is provided on the inner wall of the positioning groove 24. Specifically, in this embodiment, the limiting column 26 is convexly provided on the connecting wall 2422 of the positioning groove 24.

[0068] Please continue reading Figure 7 and Figure 8 In this embodiment, the baffle 30 is located in the limiting groove 21, and the sliding member 35 of the baffle 30 is slidably connected to the guide member 23 in the limiting groove 21. The functional member 90 is opposite to the opening 22 of the limiting groove 21. The functional member 90 is located on the side of the groove bottom wall 211 of the limiting groove 21 facing away from the baffle 30. The baffle 30 is configured to cover or expose the functional member 90. One end of the elastic member 40 is connected to the inner wall of the positioning groove 24, and the other end of the elastic member 40 is connected to the baffle 30. Specifically, in this embodiment, one end of the elastic member 40 connected to the inner wall of the positioning groove 24 is specifically connected to the connecting wall 2422 of the positioning groove 24. The elastic member 40 is configured to reset the baffle 30. When a limiting column 26 is provided in the positioning groove 24, one end of the elastic member 40 connected to the inner wall of the positioning groove 24 is sleeved on the limiting column 26. The elastic member 40 is connected to the inner wall of the positioning groove 24 through the limiting column 26.

[0069] It should be noted that, in this embodiment, the connection method of the blocking piece 30 and the guide member 23 in the limiting groove 21 can refer to the connection method of the blocking piece 30 and the guide member 23 in the first embodiment.

[0070] It is understandable that, in this embodiment, by providing a positioning groove 24 on one side of the limiting groove 21, and making the dimension of the positioning groove 24 along the direction perpendicular to the extension of the guide member 23 smaller than the dimension of the positioning groove 21 along the direction perpendicular to the extension of the guide member 23, when the elastic member 40 is installed on the mounting frame 20, one end of the elastic member 40 can be placed in the positioning groove 24 first, and then the other end can be placed in the limiting groove 21. In this way, the assembly and positioning of the elastic member 40 can be facilitated, and the movement of the elastic member 40 along the direction perpendicular to the extension of the guide member 23 can be limited, thereby improving the stability of the elastic member 40. By providing a limiting column 26 in the positioning groove 24, and making one end of the elastic member 40 sleeved on the limiting column 26, the elastic member 40 can be prevented from shaking in the positioning groove 24, thereby further improving the stability of the elastic member 40.

[0071] The present application provides a third embodiment. The third embodiment is distinguished from the first embodiment or the second embodiment in that the functional component 90 of the anesthesia machine 100 is located in the limiting groove 21. The functional component 90 of the anesthesia machine 100 is located between the blocking piece 30 and the inner wall of the limiting groove 21. The inner wall of the limiting groove 21 is not provided with an opening 22 configured to expose the functional component 90.

[0072] It should be noted that, in this embodiment, the specific implementations of the elastic member 40, the guide member 23 and the baffle 30 can all refer to the specific implementations of the elastic member 40, the guide member 23 and the baffle 30 in the first embodiment.
