[0042] Please refer to Figures 1 to 5 The anesthesia machine 100 of the embodiment of the present application comprises an oxygen cell fixing piece 10, a rack 20, and a breathing circuit 30 detachably arranged on the rack 20, and the breathing circuit 30 is provided with an oxygen detection port 31. The oxygen cell fixing piece 10 is used for accommodating an oxygen cell 40, the oxygen cell fixing piece 10 is arranged on the rack 20 and located between the rack 20 and the breathing circuit 30, the oxygen cell fixing piece 10 is provided with a mounting space 11, and at least an electrical connection end 41 of the oxygen cell 40 is detachably embedded in the mounting space 11, and a detection end 42 of the oxygen cell 40 faces the oxygen detection port 31.

[0043] In the anesthesia machine 100 of the embodiment of the present application, the oxygen cell fixing piece 10 used for accommodating the oxygen cell 40 is arranged on the rack 20 of the anesthesia machine 100 and arranged separately from the breathing circuit 30, so that when the breathing circuit 30 is detached for cleaning and disinfection or other operations, the oxygen cell 40 accommodated in the oxygen cell fixing piece 10 will not be detached together but remain in place, and the oxygen cell cable will not be affected by the detachment of the breathing circuit 30, thus properly solving the problem of accommodation and storage of the oxygen cell 40 when the breathing circuit 30 is detached in the prior art, and preventing the oxygen cell cable from being damaged, and the operation is more convenient and time-saving and labor-saving.

[0044] On the basis of the separate arrangement of the oxygen cell 40 and the breathing circuit 30, the detection end 42 of the oxygen cell 40 faces the oxygen detection port 31 of the breathing circuit 30, which can also ensure the detection effect of the oxygen cell 40 on the mixed gas circulating in the breathing circuit 30 and ensure the normal operation of the anesthesia machine 100.

[0045] The structure of the rack 20 of the anesthesia machine 100 in the embodiment of the present application can be substantially the same as that of the rack of the anesthesia machine in the prior art, and the rack 20 of the anesthesia machine 100 also simultaneously installs other basic functional structures / modules of the anesthesia machine 100, but the rack 20 and the other basic functional structures / modules do not involve the main point of the present application, and therefore are not described in detail here, and the corresponding structure of the anesthesia machine in the prior art can be referred to.

[0046] In addition, the detachable mounting manner and the corresponding structure between the breathing circuit 30 and the rack 20 in the embodiment can also refer to the detachable mounting manner and the corresponding structure between the breathing circuit and the rack in the existing anesthesia machine, which will not be described in detail here, as long as the detachable mounting between the two can be realized.

[0047] The oxygen detection port 31 on the breathing circuit 30 in the embodiment can be arranged at any suitable position to ensure that it corresponds to the oxygen cell 40 for oxygen concentration detection. The arrangement position of the oxygen detection port 31 on the breathing circuit 30 in the existing anesthesia machine 100 for oxygen concentration detection will not be limited here.

[0048] In the embodiment, the oxygen cell fixing member 10 can be fixedly or detachably arranged on the rack 20, so that the oxygen cell 40 is changed from being arranged on the breathing circuit 30 to being arranged on the rack 20, realizing the separated arrangement of the oxygen cell 40 and the breathing circuit 30. Preferably, the oxygen cell fixing member 10 is detachably arranged on the rack 20, facilitating the disassembly, replacement and maintenance of the device, etc.

[0049] In order to enable the oxygen cell fixing member 10 to accommodate the oxygen cell 40, the embodiment is provided with the installation space 11 in the oxygen cell fixing member 10. The installation space 11 can be directly constituted by the internal space of the oxygen cell fixing member 10 or additionally formed by being opened in the oxygen cell fixing member 10. Preferably, the installation space 11 is directly constituted by the internal space of the oxygen cell fixing member 10, which can simplify the manufacturing process of the oxygen cell fixing member 10 and save production cost.

[0050] The oxygen cell 40 includes an electricity connection end 41 connected with the main machine of the anesthesia machine 100, a detection end 42 for detecting oxygen concentration, and a main body part therebetween. The shape of the installation space 11 is at least adapted to the shape (external contour) of the electricity connection end 41, so as to ensure the stable accommodation of at least the electricity connection end 41 of the oxygen cell 40 in the oxygen cell fixing member 10, and further enable the stable installation of the oxygen cell 40 in the oxygen cell fixing member 10.

[0051] The detachable embedding of the electricity connection end 41 of the oxygen cell 40 in the installation space 11 can be that the electricity connection end 41 is embedded in the oxygen cell fixing member 10 and is clamped, fixed, or limited and fixed by the oxygen cell fixing member 10, etc., which can ensure the stability of the oxygen cell 40 in the oxygen cell fixing member 10, the structure of the oxygen cell fixing member 10 will be relatively simple, and the disassembly and installation of the oxygen cell 40 will be facilitated.

[0052] Preferably, the shape of the installation space 11 is adapted to the shape of the main body part of the oxygen cell 40 and the electricity connection end 41, so that most of the structure of the oxygen cell 40 can be stably embedded in the installation space 11, ensuring the stable arrangement of the oxygen cell 40 on the rack 20 and the stable connection with the breathing circuit 30.

[0053] In the present embodiment, the oxygen cell fixing member 10 is arranged on the rack 20 towards the breathing circuit 30, so that the detection end 42 of the oxygen cell 40 accommodated in the oxygen cell fixing member 10 can be directed towards the oxygen detection port 31 on the breathing circuit 30, and the detection end 42 can be directly connected with the oxygen detection port 31 (e.g., the detection end 42 is directly inserted into the oxygen detection port 31), or connected through a corresponding structure (e.g., a joint, a gas pipe, etc.), so that the oxygen cell 40 can detect the oxygen concentration of the oxygen flowing in the breathing circuit 30.

[0054] Please refer to Figures 1 to 4 Further, the oxygen cell fixing member 10 is provided with an opening 121 directed towards the rack 20, the electricity connection end 41 corresponds to the opening 121, and a wire passing space 70 is formed between the rack 20 and the upper cover 60 of the workbench of the anesthesia machine 100, and the wire passing space 70 is connected with the opening 121 and the internal interface of the anesthesia machine 100.

[0055] In the prior art, in addition to the technical problem that the oxygen cell cable is not easy to store after the oxygen cell 40 is detached from the breathing circuit 30, there is also the technical problem that the external oxygen cell cable is easy to be damaged and affects the appearance. Based on this, the wire passing space 70 for accommodating the oxygen cell cable is designed between the rack 20 and the upper cover 60 of the workbench, and the wire passing space 70 is connected with the position where the oxygen cell fixing member 10 is located and the position where the internal interface (main machine interface) of the anesthesia machine 100 is located.

[0056] In this way, when one end of the oxygen cell cable is electrically connected with the internal interface of the anesthesia machine 100, the other end can be stretched out of the wire passing space 70 to the position where the oxygen cell fixing member 10 is pre-installed. When the oxygen cell fixing member 10 is installed on the rack 20, the electricity connection end 41 of the oxygen cell 40 can be directly electrically connected with the oxygen cell cable through the opening 121 of the oxygen cell fixing member 10, and the electrical connection between the oxygen cell 40 and the main machine of the anesthesia machine 100 is quickly realized. At this time, the oxygen cell cable is accommodated in the wire passing space 70, and the oxygen cell cable can also be prevented from being damaged, and the external appearance of the anesthesia machine 100 is also ensured. Whether the breathing circuit 30 or the oxygen cell fixing member 10 is detached, the oxygen cell cable will not be affected.

[0057] Please refer to Figures 1 to 4 Further, the oxygen cell fixing member 10 comprises:

[0058] The base body 12 is detachably arranged on the rack 20, and the opening 121 is arranged on the base body 12.

[0059] The fixing portion 13 extends from the base 12 to the breathing circuit 30, and the base 12 and the fixing portion 13 form the mounting space 11. The electrical connection end 41 is detachably clamped between the base 12 and the fixing portion 13.

[0060] In this embodiment, the base 12 is located at the top of the oxygen cell fixing member 10. The oxygen cell fixing member 10 and the rack 20 are detachably arranged by detachably arranging the base 12 and the rack 20, so as to facilitate the disassembly and assembly of the oxygen cell fixing member 10 on the rack 20. The shape of the base 12 is matched with the shape of the electrical connection end 41 of the oxygen cell 40, so that the electrical connection end 41 can be stably inserted into the base 12, thereby directly corresponding to the opening 121 arranged in the middle of the base 12, and facilitating the connection of the oxygen cell 40 and the oxygen cell cable.

[0061] The fixing portion 13 has a certain length. On the basis that the electrical connection end 41 is inserted into the base 12, the fixing portion 13 can also contact the main part of the oxygen cell 40, such as being tightly matched or limited matched with the main part of the oxygen cell 40, so as to provide sufficient fixing force for the accommodation of the oxygen cell 40, and avoid the oxygen cell 40 from being separated from the oxygen cell fixing member 10.

[0062] In this embodiment, the fixing portion 13 can be one or more:

[0063] When the fixing portion 13 is one, the external contour of the fixing portion 13 can be disc-shaped, cylindrical or circular truncated cone-shaped, which can form a structure matching with the oxygen cell 40. When the oxygen cell 40 is inserted into the fixing portion 13 so that the electrical connection end 41 is located in the mounting space 11, the fixing portion 13 can directly clamp or limit the oxygen cell 40 to realize the installation of the oxygen cell 40.

[0064] When the fixing portion 13 is more than one, the fixing portion 13 can be block-shaped, sheet-shaped or strip-shaped. At this time, the fixing portion 13 can be distributed along the circumference of the base 12. Each fixing portion 13 can contact the oxygen cell 40, such as applying pressure to the oxygen cell 40 in the circumferential direction, or limiting the oxygen cell 40 in the circumferential direction, so that the oxygen cell 40 is stably limited or tightly clamped by the fixing portion 13, and the oxygen cell 40 is stably accommodated in the oxygen cell fixing member 10.

[0065] Further, the base 12 and the fixing portion 13 are integrally formed (such as integrally injection molded), that is, the oxygen cell fixing member 10 is an integral structure, which can improve the structural strength of the oxygen cell fixing member 10, and simplify the manufacturing process and save production cost.

[0066] Of course, in other embodiments, the base 12 and the fixing portion 13 can also be a split structure, which is convenient for replacement and maintenance.

[0067] Please refer toFigures 2 to 4 Further, the fixing portions 13 are multiple, and the multiple fixing portions 13 and the base body 12 jointly form the mounting space 11, and the at least electrical contact end 41 is detachably clamped between the base body 12 and the multiple fixing portions 13.

[0068] In the embodiment, the electrical contact end 41 is detachably clamped in the mounting space 11, and the electrical contact end 41 is at least in contact with the base body 12 and located in the enclosure of the multiple fixing portions 13. The multiple fixing portions 13 can be distributed along the circumference of the base body 12, and since the fixing portions 13 can be deformed to a certain extent, when the electrical contact end 41 is embedded in the mounting space 11, the multiple fixing portions 13 can at least be in close contact with the outer circumferential wall of the electrical contact end 41, and further in close contact with the outer circumferential wall of the main body part of the oxygen cell 40, so as to stably clamp and hold the oxygen cell 40 from the circumference of the oxygen cell 40.

[0069] Please continue to refer to Figures 2 to 4 Further, the multiple fixing portions 13 are uniformly and spacedly distributed on the base body 12, so that the holding force provided by the multiple fixing portions 13 to the oxygen cell 40 is more uniform, the structure of the oxygen cell fixing member 10 is more beautiful and regular, and the accommodation of the oxygen cell 40 therein is more stable.

[0070] In Figures 2 to 4 In the embodiment shown, the fixing portions 13 are three, and the three fixing portions 13 are more easily deformed than the two fixing portions 13, which can not only provide sufficient clamping force, but also will not clamp the oxygen cell 40 too tightly, and is relatively easy to disassemble and assemble. Compared with more than four fixing portions 13, the structure complexity of the oxygen cell fixing member 10 can be controlled.

[0071] Please refer to Figures 2 to 4 Further, the fixing portion 13 comprises:

[0072] The elastic sheet body 131 extending from the edge of the base body 12 to the direction of the breathing circuit 30, and the shape of the elastic sheet body 131 is matched with the shape of the outer wall of the oxygen cell 40;

[0073] The protruding ribs 132 provided on the inner side of the elastic sheet body 131 and distributed along the length direction of the elastic sheet body 131, and the oxygen cell 40 is in interference contact with the protruding ribs 132; and

[0074] The guide angle 133 provided on the inner side of the end of the elastic sheet body 131 away from the base body 12 and distributed along the width direction of the elastic sheet body 131, and the guide angle 133 is smoothly connected with the protruding ribs 132.

[0075] Specifically, the elastic sheet 131 is the main structure of the fixing part 13, and the main structure of the fixing part 13 is designed as the elastic sheet 131 which is adapted to the oxygen cell 40, so that it is easier to deform to provide clamping force, and the elastic sheet 131 with a certain length can also provide sufficient clamping force and friction to the main part of the oxygen cell 40, and can provide guidance for the installation and removal of the oxygen cell 40, and is easier to set the oxygen cell 40.

[0076] The surface of the convex rib 132 is a curved surface, and the contact area between the convex rib 132 and the oxygen cell 40 is small, which can reduce the friction with the oxygen cell 40 while ensuring the clamping force of the oxygen cell 40, and is more convenient for the installation and removal of the oxygen cell 40 between the multiple elastic sheets 131. The surface of the outward part of the structure of the convex rib 132 is a bevel, so that the oxygen cell 40 can smoothly enter the installation space 11.

[0077] In addition, the multiple convex ribs 132 on the multiple elastic sheets 131 are surrounded outside the oxygen cell 40, and the surrounding circle formed by the multiple convex ribs 132 on the multiple elastic sheets 131 is smaller than the outer diameter of the oxygen cell 40, so that the oxygen cell 40 is in interference contact with the convex rib 132, and the oxygen cell 40 can be stably accommodated in the oxygen cell fixing part 10.

[0078] Further, the convex ribs 132 on a single elastic sheet 131 are two arranged side by side, and the interference contact between the oxygen cell 40 and the convex ribs 132 on a single elastic sheet 131 is more uniform and stable.

[0079] In this embodiment, the fixing part 13 can be made of plastic, that is, the elastic sheet 131 and the convex rib 132 can be made of plastic, which has a certain structural strength and is relatively low in price, and is easier to deform to clamp and hold the oxygen cell 40. Compared with metal materials, the hardness of plastic is relatively lower, and the frictional damage to the surface of the oxygen cell 40 can be reduced.

[0080] In this embodiment, the surface of the guide angle 133 is a curved surface, and the surrounding circle surrounded by the multiple guide angles 133 on the multiple elastic sheets 131 is slightly larger than the outer diameter of the oxygen cell 40, which is easier to align and install the oxygen cell 40, that is, it is easier to embed / clamp the oxygen cell 40 into the surrounding circle of the multiple guide angles 133, and there is no large gap between the oxygen cell 40 and the guide angle 133, which ensures the tightness between the elastic sheet 131 and the oxygen cell 40, and through the smooth connection of the guide angle 133 and the convex rib 132, the sliding embedding of the oxygen cell 40 is easier.

[0081] Please refer to Figures 2 to 4 Further, the oxygen cell fixing part 10 further comprises multiple mounting parts 14 arranged on the side edges of the base body 12, and the base body 12 is arranged on the rack 20 by penetrating the mounting part 14 with a fastener.

[0082] Specifically, the mounting portion 14 extends outwardly from the side of the base body 12, and a screw hole or a through hole capable of allowing a fastener to pass through is formed in the mounting portion 14. Correspondingly, a hole groove is formed in the rack 20, and the fastener can be a screw or a rivet or the like having a fastening function. The oxygen cell fixing piece 10 can be mounted on the rack 20 by connecting the hole groove in the rack 20 with the hole in the mounting portion 14 through the fastener.

[0083] Preferably, the hole in the mounting portion 14 and the hole groove in the rack 20 can be screw holes, and the fastener can be a screw. In this way, the oxygen cell fixing piece 10 can be stably mounted on the rack 20 through threaded connection, and the oxygen cell fixing piece 10 can be easily and detachably arranged on the rack 20.

[0084] In the embodiment, the mounting portion 14 is two, and the two mounting portions 14 are oppositely arranged on the base body 12. The oxygen cell fixing piece 10 can be stably arranged on the rack 20 while the structural complexity of the oxygen cell fixing piece 10 is controlled.

[0085] Of course, in other embodiments, the mounting portion 14 can also be three, four or more in number to improve the stability of the oxygen cell fixing piece 10 mounted on the rack 20, and the number can be set according to specific requirements.

[0086] Please refer to Figures 1 to 4 Furthermore, the oxygen cell fixing piece 10 further comprises a positioning column 15 arranged on the top of the base body 12. The positioning column 15 protrudes from the base body 12 towards the rack 20 and corresponds to a positioning groove 21 arranged on the rack 20.

[0087] When the oxygen cell fixing piece 10 is mounted on the rack 20, the top of the oxygen cell fixing piece 10 is in contact with the rack 20, that is, the top of the base body 12 is in contact with the rack 20. Therefore, in order to accurately correspond the base body 12 to the rack 20, one or more positioning columns 15 protruding from the top of the base body 12 are arranged in the embodiment, and a positioning groove 21 corresponding to the positioning column 15 is arranged on the base body 12. The positioning column 15 is matched with the positioning groove 21. When the oxygen cell fixing piece 10 is mounted on the rack 20, the positioning column 15 is first aligned with the positioning groove 21 and embedded therein, so that the oxygen cell fixing piece 10 is accurately located at the pre-installation position, and then the oxygen cell fixing piece 10 is mounted on the rack 20 through the corresponding mounting mode.

[0088] In addition, the positioning column 15 can also play a certain fixing role. For example, the positioning column 15 is designed to be tightly matched with the positioning groove 21. Therefore, the positioning column 15 and the positioning groove 21 can also be used as a structure for detachable connection of the oxygen cell fixing piece 10 and the rack 20. By designing multiple positioning columns 15 and multiple positioning grooves 21 to be tightly matched, the stable mounting of the oxygen cell fixing piece 10 on the rack 20 can be achieved.

[0089] More, the position of the positioning column 15 is designed between the two mounting portions 14 on the base 12, so that the connection between the oxygen cell fixing member 10 and the rack 20 is more uniform, and the structure of the oxygen cell fixing member 10 is more regular.

[0090] In the embodiment, the base 12, the fixing portion 13, the mounting portion 14 and the positioning column 15 are integrally formed to form the oxygen cell fixing member 10, which can simplify the manufacturing process of the oxygen cell fixing member 10, reduce the production cost, and improve the structural strength of the oxygen cell fixing member 10.

[0091] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 Furthermore, the anesthesia machine 100 further comprises an oxygen cell base 50, which is detachably arranged on the detection end 42 of the oxygen cell 40, and a through air passage 51 is arranged on the end face of the oxygen cell base 50.

[0092] In the embodiment, the oxygen cell 40 is connected with the breathing circuit 30 through the oxygen cell base 50, and the oxygen cell base 50 can be regarded as a joint between the oxygen cell 40 and the breathing circuit 30. Since the detection end 42 of the oxygen cell 40 faces the breathing circuit 30, when the oxygen cell base 50 is arranged on the detection end 42, the through air passage 51 on the oxygen cell base 50 can face the oxygen detection port 31 of the breathing circuit 30. The oxygen cell base 50 can shield the detection end 42 to reduce the interference of oxygen in the atmosphere, and the correspondence between the through air passage 51 and the oxygen detection port 31 makes the mixed gas more concentrated. The detection end 42 can more accurately detect the mixed gas flowing through the oxygen detection port 31 through the through air passage 51.

[0093] Exemplarily, the detachable arrangement between the oxygen cell base 50 and the detection end 42 can be that the oxygen cell base 50 is clamped on the detection end 42 (such as interference fit, setting clamping structure, etc.), or the oxygen cell base 50 and the detection end 42 are detachably connected through a connecting structure (such as a threaded structure), which can be set according to specific needs.

[0094] In addition, the oxygen cell base 50 can be fixedly arranged on the breathing circuit 30 and communicated with the oxygen detection port 31 (such as being directly arranged at the oxygen detection port 31), that is, the oxygen cell base 50 can be regarded as a part of the breathing circuit 30. When it is needed to connect the oxygen cell 40 and the breathing circuit 30 together, the oxygen cell base 50 is connected with the detection end 42 in correspondence, so that the connection between the breathing circuit 30 and the oxygen cell 40 is realized, and the connection process between the breathing circuit 30 and the oxygen cell 40 is simplified.

[0095] Alternatively, the oxygen cell base 50 can be provided as a separate part which is detachable from the oxygen cell 40 and the breathing circuit 30. When the oxygen cell 40 and the breathing circuit 30 need to be connected together, the oxygen cell base 50 is first mounted on the detection end 42, and then the gas passage 51 is correspondingly connected to the oxygen detection port 31 on the breathing circuit 30, so that the breathing circuit 30 and the oxygen cell 40 are connected. In this way, the oxygen cell base 50 can be replaced and maintained conveniently, and the structure of the breathing circuit 30 does not need to be changed too much.

[0096] Further, the oxygen cell base 50 is detachably connected to the breathing circuit 30. When the oxygen cell base 50 is connected to the breathing circuit 30, the gas passage 51 is in communication with the oxygen detection port 31.

[0097] That is, the oxygen cell base 50 is detachably provided as a separate part between the detection end 42 of the oxygen cell 40 and the breathing circuit 30, and is specifically located between the detection end 42 and the gas passage 51. In actual installation, the oxygen cell 40 is first embedded in the oxygen cell fixing member 10, and then the detection end 42 of the oxygen cell 40 is correspondingly provided with the oxygen cell base 50. After that, the oxygen detection port 31 is correspondingly connected to the gas passage 51, and finally the breathing circuit 30 is installed on the rack 20, so that the detection end 42 and the breathing circuit 30 are stably connected.

[0098] When the breathing circuit 30 is detached, the oxygen cell base 50 is still mounted on the detection end 42, the oxygen cell 40 is still accommodated in the oxygen cell fixing member 10, and the oxygen cell fixing member 10 is still mounted on the rack 20. Both the oxygen cell fixing member 10 and the oxygen cell base 50 can be independently detached and replaced.

[0099] Further, the inner side of the circumferential surface of the oxygen cell base 50 is formed with a threaded structure, the detection end 42 is screwed with the oxygen cell base 50, that is, the oxygen cell base 50 and the oxygen cell 40 are connected through screwing. The screwing connection has high connection stability and high repeatability (i.e. can be repeatedly connected), and facilitates the assembly and disassembly of the oxygen cell base 50.

[0100] In actual installation, the oxygen cell 40 is embedded in the oxygen cell fixing member 10, and at this time the detection end 42 is exposed outside the oxygen cell fixing member 10. After the oxygen cell base 50 is correspondingly provided with the detection end 42, the oxygen cell base 50 is mounted on the detection end 42 by rotating the oxygen cell base 50 through the threaded structure. After that, the oxygen cell base 50 is detached from the detection end 42 by reversely rotating the oxygen cell base 50.

[0101] Please refer to Figure 1 , Figure 2 and Figure 5 Further, the oxygen cell base 50 comprises:

[0102] The reinforcing rib 52 is arranged on the end surface of the oxygen cell base 50;

[0103] The sealing ring 53 is arranged on the circumferential surface of the oxygen cell base 50; and

[0104] The base flat portion 54 is arranged on the circumferential surface of the oxygen cell base 50, extends away from the end surface of the oxygen cell base 50, and has a fixing space 541 for accommodating the detection end 42, which is in communication with the gas passage 51.

[0105] Specifically, the gas passage 51 is arranged on the end surface of the oxygen cell base 50, which is formed on the butt joint portion of the oxygen cell base 50 protruding towards the breathing circuit, i.e. the gas passage 51 is arranged on the butt joint portion, the butt joint portion can be embedded into the oxygen detection port 31 so that the gas passage 51 is in communication with the oxygen detection port 31 and the oxygen cell base 50 is connected with the breathing circuit 30, and the reinforcing rib 52 is arranged in the butt joint portion, which can improve the structural strength of the butt joint portion so that the butt joint portion is not easy to deform and the normal connection between the oxygen cell base 50 and the breathing circuit 30 is ensured.

[0106] In addition, the butt joint portion can be made of plastic, rubber or other materials that can be deformed, and the size of the butt joint portion can be slightly larger than that of the oxygen detection port 31, so that the butt joint portion is more easily embedded into the oxygen detection port 31 after being slightly compressed and deformed, and the cooperation between the butt joint portion and the oxygen detection port 31 is more closely, which reduces the overflow of oxygen from the connection between the butt joint portion and the breathing circuit 30 and ensures the accuracy of the oxygen concentration detection of the oxygen cell 40. At this time, the reinforcing rib 52 can prevent the butt joint portion from being deformed too much, so that the butt joint portion can maintain the basic structural form and ensure the normal connection with the breathing circuit 30, i.e. ensure the normal flow of gas.

[0107] Further, the sealing ring 53 can be a rubber ring, a plastic ring or other structures that can be deformed, which is arranged outside the butt joint portion and can be used to seal the connection between the oxygen detection port 31 and the butt joint portion, so as to improve the airtightness of the connection between the butt joint portion and the breathing circuit 30, reduce the overflow of mixed gas from the connection between the butt joint portion and the breathing circuit 30, and ensure the accuracy of the oxygen concentration detection of the oxygen cell 40.

[0108] In the embodiment, the base flat portion 54 can be composed of a plurality of rectangular surface structures, which are distributed along the circumferential surface of the oxygen cell base 50, so that the cross section of the oxygen cell base 50 is roughly polygonal, such as regular pentagon, regular hexagon, etc. In this way, the oxygen cell base 50 is more easily rotated under force, so that the connection stability between the oxygen cell base 50 and the detection end 42 is improved by rotating the oxygen cell base 50.

[0109] Since the fixing space 541 formed in the base flat position 54 is communicated with the air passing port 51, when the detection end 42 of the oxygen cell 40 is clamped in the base flat position 54, the detection end 42 can correspond to the air passing port 51, and after the air passing port 51 is communicated with the oxygen detection port 31, the detection end 42 can detect the oxygen in the breathing circuit 30.

[0110] Please refer to Figures 1 to 3 Further, the oxygen cell fixing member 10 and the oxygen cell base 50 surround the oxygen cell 40, and the shape of the space surrounded by the oxygen cell fixing member 10 and the oxygen cell base 50 is adapted to the shape of the oxygen cell 40.

[0111] It can be understood that the space surrounded by the oxygen cell fixing member 10 and the oxygen cell base 50 is the space formed by the communication of the mounting space 11 and the fixing space 541, that is, the mounting space 11 and the fixing space 541 constitute the space, so the shape of the space surrounded by the oxygen cell fixing member 10 and the oxygen cell base 50 is actually that the shape of the detection end 42 of the oxygen cell 40 is adapted to the shape of the fixing space 541, and the shape of the oxygen cell 40 except the detection end 42 is adapted to the mounting space 11, which improves the accommodation stability of the oxygen cell 40 between the oxygen cell fixing member 10 and the oxygen cell base 50, and reduces the gap between the oxygen cell 40 and the above two, thereby reducing the pollution caused by impurities entering the space.
