[0048] Please refer to Figure 1 , Figure 2 as well as Figure 3 The present invention provides an anesthesia machine base 10.

[0049] In one embodiment of the present invention, the anesthesia machine base 10 includes a base body 11, multiple wheels 13, a brake assembly 15 and a limit assembly 17; wherein the multiple wheels 13 are rotatably arranged on the base body 11; the brake assembly 15 includes a pressing piece 151 and multiple abutting pieces 153, the pressing piece 151 is movably arranged on the base body 11, the multiple abutting pieces 153 are all connected to the pressing piece 151, and have a locking position when driven by the pressing piece 151, when the abutting piece 153 is in the locking position, one abutting piece 153 abuts against one wheel 13, so that the multiple wheels 13 are all limited and fixed relative to the base body 11; the limit assembly 17 is arranged on the base body 11 and is connected to the pressing piece 151, when the abutting piece 153 is in the locking position, the limit assembly 17 can limit and fix the pressing piece 151 relative to the base body 11.

[0050] In one embodiment of the present invention, the base body 11 can be used to install and carry wheels 13 and limiter components 17, etc., so that the various components of the anesthesia machine base 10 can form an integral body and facilitate the one-time completion of the connection with the anesthesia machine body 30 of the anesthesia machine 100. Among them, the base body 11 can be roughly square in structure, and its corner areas are provided with rotatable wheels 13, specifically, the four corner areas can be provided with wheels 13, or three, five or more wheels 13 are provided around the center of the base body 11. Of course, in order to improve the stability of the anesthesia machine base 10 placed on the ground, the base body 11 can also extend a protrusion outward from the corner area, and the wheel 13 is provided on the protrusion of the base body 11, so that the distance between the wheels 13 is relatively large and the base body 11 is supported more stably. In addition, in order to reduce the overall mass of the base body 11, the material of the base body 11 can be a plastic material, so as to facilitate the push of medical staff. Of course, the present application is not limited to this. In other embodiments, the material of the base body 11 can also be a metal material. The wheel 13 can be used to roll against the ground, so that the anesthesia machine base 10 is rolling friction on the ground and the friction is reduced, so as to facilitate the medical staff to push the anesthesia machine base 10. Among them, the wheel 13 can be a one-way wheel, that is, it can only rotate in one direction. Of course, the wheel 13 can also be a universal wheel, that is, it can rotate in multiple directions along the circumference. The pressing member 151 of the brake assembly 15 can be used to be driven by an external force, that is, for the medical staff to drive, specifically, it can be driven by the foot of the medical staff, or it can be driven by the hand of the medical staff. The abutment member 153 can be used to abut the wheel 13, so that the wheel 13 is fixed relative to the base body 11 to achieve the braking of the anesthesia machine 100. Among them, the abutment member 153 can be an arc surface on the wall surface abutting against the wheel 13, so as to adapt to the wheel 13 and increase the pressing force on the wheel 13. The limiting component 17 can be used to limit the pressing member 151, that is, when the pressing member 151 is driven to drive the abutment member 153 to press against the wheel 13 to complete braking, the limiting component 17 can limit and fix the pressing member 151 relative to the base body 11 at this time, thereby achieving the continuous maintenance of the anesthesia machine 100 in the braking state.

[0051] When the anesthesia machine base 10 of the technical solution of the present invention is applied to the anesthesia machine 100, the pressing member 151 is driven to move relative to the base body 11, and the multiple abutting members 153 are driven to move. Afterwards, when the multiple abutting members 153 are close to at least the multiple wheels 13 on the base body 11, they can be abutted against the first wheel 13 through an abutting member 153, so that the multiple wheels 13 are all fixed relative to the base body 11, thereby completing the braking limit of the multiple wheels 13 at one time. That is, the anesthesia machine base 10 in this solution only needs to drive the pressing member 151 once when performing the braking operation to complete the braking limit of the multiple wheels 13. Compared with the anesthesia machine 100 in the prior art, when performing the braking operation, each of the multiple wheels 13 needs to be braked once to complete the braking limit of the multiple wheels 13. The number of braking operations of the anesthesia machine base 10 in this solution is less, which simplifies the braking operation process of the anesthesia machine 100, thereby reducing the labor intensity of medical staff.

[0052] In addition, the anesthesia machine base 10 in this solution further includes a limiting assembly 17, so that when the abutting member 153 abuts against the wheel 13 and is in the locking position, the limiting assembly 17 can limit and fix the pressing member 151 relative to the base body 11. That is, the limiting assembly 17 can keep the anesthesia machine 100 in the brake limit state continuously, without the medical staff having to manually limit the pressing member 151 of the brake assembly 15 continuously, thereby further reducing the labor intensity of the medical staff.

[0053] Please refer to Figure 3 and Figure 4 In one embodiment of the present invention, the brake assembly 15 also includes at least two transmission rods 155, and the at least two transmission rods 155 are movably disposed on the base body 11. Each transmission rod 155 is connected to at least two abutment members 153. The at least two transmission rods 155 are also transmission-connected to the pressing member 151. The pressing member 151 drives the at least two abutment members 153 by driving the transmission member to move.

[0054] It can be understood that the pressing member 151 drives the abutting member 153 through the transmission rod 155, which reduces the requirements of the pressing member 151 on the position setting, thereby facilitating the installation convenience of the pressing member 151. Moreover, such a setting also allows the pressing member 151 to drive multiple abutting members 153 only by driving at least two transmission rods 155. At this time, the structure of the pressing member 151 can be set relatively simple, thereby facilitating the manufacturing convenience of the pressing member 151. Of course, the present application is not limited to this, and in other embodiments, it is also possible for the pressing member 151 to directly drive the abutting member 153.

[0055] Please refer to Figure 3 and Figure 4 In one embodiment of the present invention, each transmission rod 155 includes two main sections 1551 and a connecting section 1553. The two main sections 1551 are rotatably disposed on the base body 11, and the rotation axes of the two main sections 1551 are located on the same straight line. A contact piece 153 is provided at the same end of the two main sections 1551; the two ends of the connecting section 1553 are respectively connected to one end of the two main sections 1551 away from the contact piece 153, and the connecting section 1553 is transmission-connected to the pressing piece 151. The pressing piece 151 drives the transmission rod 155 to rotate to drive the two contact pieces 153.

[0056] It can be understood that the two main sections 1551 of the transmission rod 155 are rotatably arranged on the base body 11, so that the transmission rod 155 can be driven by the lever principle, that is, the end of the main section 1551 close to the connecting section 1553 can be driven with a small force so that the abutment 153 at the end of the main section 1551 away from the connecting section 1553 has a large abutment force on the vehicle, thereby making the braking process of the anesthesia machine 100 more labor-saving and further reducing the labor intensity of medical staff, while ensuring the stability of the brake limit of the wheel 13. Among them, the two main sections 1551 and the connecting section 1553 are roughly surrounded by a U-shaped structure, which makes the structure of the transmission rod 155 relatively simple and easy to shape and manufacture. Of course, the present application is not limited to this. In other embodiments, the two main sections 1551 of the transmission rod 155 can be lifted and lowered on the base body 11, and it is also possible to drive the abutment 153 during the lifting process. Alternatively, the transmission rod 155 is directly an annular rod, which is escalably disposed on the base body 11, and the abutment member 153 is disposed around the annular rod, and the wheel 13 is braked or unlocked during the lifting process of the annular rod.

[0057] Please refer to Figure 3 and Figure 4 In one embodiment of the present invention, there are two transmission rods 155, the two transmission rods 155 are arranged opposite to each other, and the connecting section 1553 in one transmission rod 155 is close to the connecting section 1553 in the other transmission rod 155; the brake assembly 15 also includes an adapter plate 157, which is liftably arranged on the base body 11 and is located below the two connecting sections 1553 of the two transmission rods 155. The adapter plate 157 is also transmission-connected to the pressing member 151, and the pressing member 151 drives the two main sections 1551 to rotate by driving the adapter plate 157 to rise.

[0058] It can be understood that two transmission rods 155 are symmetrically arranged, and in this case, four wheels 13 can be correspondingly arranged, that is, the four wheels 13 can be respectively located at the four corners of the base body 11, so as to better support the base body 11. At the same time, the number of transmission rods 155 is relatively small, which can reduce the possibility of interference, thereby facilitating the arrangement of structures such as the adapter plate 157 and the pressing member 151 on the base body 11. Of course, the present application is not limited to this, and it is also possible to set three or more transmission rods 155.

[0059] Please refer to Figure 3 and Figure 4 In one embodiment of the present invention, the two connecting sections 1553 of the two transmission rods 155 are each provided with an abutting section 1555, and the two abutting sections 1555 extend in a direction approaching each other. The ends of the two abutting sections 1555 that are close to each other are each provided with a rotatable first bearing 1557, and the side circumferential surfaces of the two first bearings 1557 are both in abutment with the upper surface of the adapter plate 157.

[0060] It can be understood that the setting of the abutment section 1555 increases the force arm acting on the transmission rod 155, so that a smaller force can be applied there to facilitate driving the transmission rod 155 to rotate, which is more conducive to the effort-saving effect when driving the pressing member 151. The setting of the first bearing 1557 can make the transmission rod 155 and the adapter plate 157 in rolling contact, reduce the resistance encountered by both during transmission, and thus help to improve the smoothness of the anesthesia machine 100 during the braking operation. At the same time, the two abutment sections 1555 extend in a direction close to each other, so that the abutment section 1555 and the connecting section 1553 are set at an obtuse angle, so that the rising adapter plate 157 can be better avoided.

[0061] Please refer to Figure 3 and Figure 4 In one embodiment of the present invention, a guide column 1571 is provided on the upper surface of the adapter plate 157, and the guide column 1571 is extended along the lifting direction of the adapter plate 157. A guide sleeve 111 is provided at a position of the base body 11 corresponding to the guide column 1571, and an end of the guide column 1571 away from the base body 11 can be lifted and inserted into the guide sleeve 111.

[0062] It can be understood that the coordinated arrangement of the guide post 1571 and the guide sleeve 111 has a guiding effect on the rising process of the adapter plate 157, which can ensure the stable rising of the adapter plate 157, and further ensure that the transmission rod 155 drives the abutment 153 to stably press and limit the wheel 13.

[0063] Please refer to Figure 3 and Figure 4In one embodiment of the present invention, the pressing member 151 is rotatably disposed on the base body 11 , one end of the pressing member 151 is located below the adapter plate 157 , and the other end can be driven by an external force and is transmission-connected to the limit assembly 17 .

[0064] It can be understood that the rotatable setting of the pressing member 151 allows the pressing member 151 to be further driven by the lever principle, that is, the end of the pressing member 151 used for external force driving can be driven by a smaller force so that the end of the pressing member 151 used for abutting and driving the adapter plate 157 has a larger abutting force on the adapter plate 157, thereby making the braking process of the anesthesia machine 100 more labor-saving and further reducing the labor intensity of medical staff. At the same time, one end of the pressing member 151 is located below the adapter plate 157, which also makes there is no connection between the pressing member 151 and the adapter plate 157, so that the change in the projection distance in the horizontal direction between the end of the pressing member 151 close to the adapter plate 157 and the rotation axis of the pressing member 151 will not affect the adapter plate 157, and there is no need to set a corresponding distance adjustment structure, which is conducive to simplifying the structure of the anesthesia machine base 10. Of course, the present application is not limited thereto, and in other embodiments, one end of the pressing member 151 is connected to the top of the adapter plate 157 to drive the adapter plate 157 when rotating. In this case, a section of the pressing member 151 between the end connected to the adapter plate 157 and the rotation axis of the pressing member 151 can be set to be retractable to adapt to the change in the horizontal projection distance between the end of the pressing member 151 close to the adapter plate 157 and the rotation axis of the pressing member 151. Alternatively, the pressing member 151 is directly arranged on the base body 11 in a liftable manner along the up-down direction.

[0065] Please refer to Figure 3 and Figure 4 In one embodiment of the present invention, a rotatable second bearing 1511 is provided at one end of the pressing member 151 located below the adapter plate 157 , and a side circumferential surface of the second bearing 1511 abuts against a lower surface of the adapter plate 157 .

[0066] It can be understood that the setting of the second bearing 1511 can make the pressing member 151 and the adapter plate 157 in rolling contact, reduce the resistance encountered by both during transmission, and thus help to further improve the smoothness of the anesthesia machine 100 during the braking operation process.

[0067] Please refer to Figures 3 to 8In one embodiment of the present invention, the limiting assembly 17 includes a mounting tube 171, a locking member 173, a pushing column 175 and a first elastic member 178. The mounting tube 171 is arranged on the multi-base body 11. A limiting rib 172 is arranged in the mounting tube 171. The limiting rib 172 extends along the axial direction of the mounting tube 171. A first guide inclined surface 172a is formed at the lower end of the limiting rib 172. The locking member 173 is movably arranged in the mounting tube 171. A plurality of oblique tooth grooves 173a are arranged around the upper end of the locking member 173. A groove side wall of the oblique tooth groove 173a is arranged in parallel with the first guide inclined surface 172a. A limiting groove 173b is arranged between two adjacent oblique tooth grooves 173a. The limiting rib 172 Embedded in the limiting groove 173b, the lower end of the locking member 173 also extends out of the mounting tube 171 and abuts against the upper wall surface of the pressing member 151; the pushing column 175 is inserted into the mounting tube 171 in a liftable manner and is located at the upper end of the locking member 173, and the lower end of the pushing column 175 is provided with a plurality of oblique convex teeth 177, one oblique convex tooth 177 is arranged opposite to an oblique tooth groove 173a, and the oblique convex tooth 177 corresponds to the side wall of the groove side wall in the oblique tooth groove 173a which is arranged parallel to the first guide bevel 172a to form a second guide bevel 177a, and the second guide bevel 177a and the first guide bevel 172a are arranged parallel to each other; the first elastic member 178 elastically abuts against the mounting tube 171 and the locking member 173.

[0068] It can be understood that, in such a configuration, when the push post 175 is not pressed, the limiting rib 172 is embedded in the limiting groove 173b. When the push post 175 is pressed and lowered, the second guide inclined surface 177a of the push post 175 can abut against and drive the locking member 173 to descend. At this time, the limiting rib 172 is embedded in the limiting groove 173b and gradually separates in the vertical direction, and when the locking member 173 descends to the groove side wall of an oblique tooth groove 173a and the first guide inclined surface 172a of the limiting rib 172 are located on the same inclined surface, the locking member 173 is driven to rotate a certain angle along the first guide inclined surface 172a due to the elastic force of the first elastic member 178, and the push post 175 can be raised and reset, so that the limiting rib 172 is embedded in the oblique tooth groove 173a. The position of the beveled tooth groove 173a is higher than the position of the limiting groove 173b, which means that the locking member 173 is limited after it has been lowered a certain distance, and thus the locking member 173 is abutted against the locking member 173 after it has been lowered a certain distance. When the anesthesia machine 100 is braked and unlocked, the push column 175 is continuously pressed, and the second guide inclined surface 177a of the push column 175 can continue to abut against and drive the locking member 173 to descend. At this time, the limiting rib 172 is embedded in the beveled tooth groove 173a corresponding to the limiting rib 172 and gradually separates in the up and down directions. When the locking member 173 descends to the point where the groove side wall of the beveled tooth groove 173a adjacent to the beveled tooth groove 173a and the first guide inclined surface 172a of the limiting rib 172 are located on the same inclined surface, under the action of the first elastic member 178, the locking member 173 can continue to rotate a certain angle along the first guide inclined surface 172a. At the same time, the limiting rib 172 may correspond to another limiting groove 173b and be embedded in the limiting groove 173b. At this time, the locking member 173 is reset to the initial height, and the pressing member 151 abutting against the locking member 173 is also reset to the initial height to complete the unlocking. Therefore, the limiting assembly 17 set in this way can complete the braking operation by pressing for the first time, and keep the anesthesia machine 100 in the braking state, and then the unlocking operation can be completed by pressing for the second time. The unlocking action is effectively simplified, thereby further reducing the labor intensity of medical staff. Among them, the first elastic member 178 can be a spring, silica gel or other plastic parts with a certain elasticity. In addition, it should be noted that the present application is not limited to this. In other embodiments, the limiting assembly 17 can also be directly a screw, that is, when the pressing member 151 is driven to put the anesthesia machine 100 in the braking state, it is also possible to limit the position directly by inserting the screw.

[0069] Please refer to Figure 5 or Figure 6 In one embodiment of the present invention, the limiting assembly 17 further includes a second elastic member 179 , and the second elastic member 179 elastically abuts against the mounting tube 171 and the pushing column 175 .

[0070] It can be understood that the second elastic member 179 is provided so that the push column 175 can automatically reset after being lowered without manual reset, which is beneficial to improve the automation of the limit assembly 17. The second elastic member 179 can be a spring, silicone or other plastic member with a certain elasticity.

[0071] Please refer to Figure 2 and Figure 3 In one embodiment of the present invention, the base body 11 is provided with an elastic foot pedal 113 at a position corresponding to the push column 175. When an external force acts on the foot pedal 113, the foot pedal 113 can approach and drive the push column 175 to descend.

[0072] It can be understood that the foot pedal 113 is provided to facilitate the placement and force of the feet of the medical staff. That is, the medical staff steps on the foot pedal 113 to drive the push column 175 downward when the foot pedal 113 is deformed downward, so as to complete the pressing and driving operation of the pressing member 151.

[0073] The present invention further provides an anesthesia machine 100, which includes an anesthesia machine base 10 and an anesthesia machine body 30. The specific structure of the anesthesia machine base 10 refers to the above embodiment. Since the anesthesia machine 100 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the anesthesia machine body 30 is arranged on the anesthesia machine base 10.

[0074] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
