The invention provides an anesthesia machine.
Referring to fig. 1 to 4, in an embodiment of the present invention, the anesthesia apparatus includes a frame 10, a plurality of wheels 30, a plurality of braking mechanisms 50, and a controller 70; wherein, a plurality of wheels 30 are rotatably arranged on the frame 10; a brake mechanism 50 is arranged corresponding to a wheel 30, the brake mechanism 50 comprises a first elastic member 51, a locking assembly 53 and an electromagnet 55, the first elastic member 51 is arranged on the frame 10, the locking assembly 53 is movably arranged on the frame 10 and connected with the first elastic member 51, the first elastic member 51 drives the locking assembly 53 to abut against the wheel 30 corresponding to the locking assembly 53, so that the wheel 30 is limited and fixed relative to the frame 10, the electromagnet 55 is arranged on the frame 10 and can drive the locking assembly 53 to be separated from the wheel 30 after being electrified; the controller 70 is disposed on the frame 10 and electrically connected to the plurality of electromagnets 55 of the plurality of braking mechanisms 50.
In one embodiment of the present invention, the housing 10 may be used to mount and carry a plurality of wheels 30, a brake housing 10, and other components of the anesthesia machine such as the controller 70, so that the components of the anesthesia machine may be assembled into a single unit for easy handling and management. The frame 10 may include a base 11 and a body 13, the body 13 is disposed at an upper end of the base 11, at this time, the plurality of wheels 30 and the plurality of brake mechanisms 50 may be disposed on the base 11, and the controller 70 may be disposed on the body 13. In order to reduce the overall quality of the anesthesia machine and facilitate the pushing of the anesthesia machine by medical personnel during use, the frame 10 may be made of plastic. The wheels 30 may be adapted to roll against the ground to reduce friction of the housing 10 against the ground for rolling friction, thereby facilitating the pushing of the anesthesia machine by the medical personnel. The wheel 30 may be a one-way wheel, i.e. can only rotate in one direction. Of course, the wheel 30 may be a universal wheel, i.e., may rotate in a plurality of directions in the circumferential direction. The number of the wheels 30 may be three, four or more, and the like, and in this case, three, four or more, and the like, may be correspondingly provided for the braking mechanism 50. The first elastic member 51 in the braking mechanism 50 can be used to provide power to drive the locking component 53 to approach and abut against the wheel 30 corresponding to the locking component 53, so that the wheel 30 is fixed in a limited manner relative to the frame 10. The first elastic member 51 can be a spring, and the spring has the advantages of good elasticity and low cost, so that the first elastic member 51 can be ensured to drive the locking component 53 to stably abut against a vehicle, and the manufacturing cost of the first elastic member 51 is reduced. Of course, the present disclosure is not limited thereto, and in other embodiments, the first elastic member 51 may also be plastic or other plastic members with certain elasticity. The electromagnet 55 can also provide power, that is, the locking assembly 53 can be attracted after the electromagnet 55 is powered on, and at this time, the locking assembly 53 can overcome the driving force of the first elastic element 51 and move in the direction away from the wheel 30 to be separated from the wheel 30, so that the wheel 30 is not limited and fixed relative to the frame 10. The controller 70 can be used for controlling the switching between the power-on state and the power-off state of the electromagnet 55, that is, when the braking limit of the anesthesia machine is required, the controller 70 controls the electromagnet 55 to be powered off, so that the locking assembly 53 is only acted by the first elastic element 51; when the anesthesia machine needs to be braked and unlocked, the controller 70 controls the electromagnet 55 to be electrified, so that the locking assembly 53 is driven by the electromagnet 55 to overcome the action of the first elastic piece 51.
When the anesthesia machine of the technical scheme of the invention is used, the controller 70 controls the electromagnets 55 in the plurality of brake mechanisms 50 to be powered off, and at the moment, the locking assemblies 53 in the plurality of brake mechanisms 50 are only driven by the first elastic element 51 to correspondingly abut against the wheels 30, so that the wheels 30 are limited and fixed relative to the frame 10, and the braking limitation of the anesthesia machine is completed. Because the plurality of brake mechanisms 50 in the present embodiment are synchronously operated, compared with the anesthesia machine in the prior art that when the brake operation is performed, the brake limitation on the plurality of wheels 30 can be completed only by stepping on the brake once for each wheel 30 in the plurality of wheels 30, the anesthesia machine in the present embodiment completes the brake limitation on the plurality of wheels 30 at one time through the synchronous operation of the plurality of brake mechanisms 50. Therefore, the brake operation process of the anesthesia machine is simplified, and the labor intensity of medical personnel is reduced. When the anesthesia machine is braked and unlocked, the controller 70 controls the electromagnets 55 in the plurality of brake mechanisms 50 to be electrified, the electrified electromagnets 55 can adsorb the corresponding locking assemblies 53 to drive the locking assemblies 53 to be separated from the wheels 30, so that the brake unlocking of the plurality of wheels 30 is completed, and the controller 70 controls the electromagnets 55 in the plurality of brake mechanisms 50 to be electrified to complete the brake unlocking of the plurality of wheels 30 at one time, so that the brake unlocking process is simple, and the labor intensity of medical workers is further reduced.
Referring to fig. 2 to fig. 6, in an embodiment of the present invention, the locking assembly 53 includes an abutting member 531 and a transmission member 535, wherein the abutting member 531 is disposed on the frame 10 in a liftable manner; the transmission member 535 is rotatably disposed on the frame 10, and defines that the transmission member 535 has two opposite ends, and one end of the transmission member 535 is connected to the first elastic member 51 and can be driven by the electromagnet 55 after being electrified; when the first elastic member 51 drives the transmission member 535 to rotate, one end of the transmission member 535 far from the first elastic member 51 can abut against and drive the abutting member 531 to descend, so that the abutting member 531 abuts against the wheel 30.
It can be understood that the locking component 53 abuts and limits the wheels 30 through the liftable abutting parts 531, so that the pressing force of each abutting part 531 on each wheel 30 is downward along the vertical direction, the wheels 30 can be better clamped and limited with the ground, and the braking limiting effect of the locking component 53 on the wheels 30 is improved. The rotatable transmission member 535 is disposed such that the first elastic member 51 and the electromagnet 55 can be disposed on two opposite sides of the transmission member 535, so as to reduce the possibility of interference between the two, thereby facilitating the installation of the transmission member 535, and facilitating the driving of the transmission member 535 by the two. The transmission member 535 may extend substantially in a vertical direction, the first elastic member 51 and the electromagnet 55 may be respectively located at two opposite sides of the upper end of the transmission member 535, and the lower end of the transmission member 535 is used for abutting against and driving the abutting member 531 to descend. Of course, the transmission member 535 may also be disposed to extend in a substantially horizontal direction, and the first elastic member 51 and the electromagnet 55 may be respectively located at two opposite sides of the transmission member 535 in a vertical direction. The rotation limit of the transmission member 535 may be that one end of the transmission member 535 close to the first elastic member 51 directly abuts against the frame 10 to limit the rotation stroke when the end is driven by the first elastic member 51 to rotate to abut against the upper surface of the abutting member 531. Thus, the excessive rotation of the driving member 535 driven by the first elastic member 51 can be avoided, so that the driving member 535 can be kept in a state of abutting against the upper surface of the abutting member 531, and the abutting member 531 is kept in a state of abutting against the wheel 30, thereby realizing the maintenance of the braking state of the anesthesia machine. Of course, the frame 10 may be additionally provided with a stopper 113, and the stopper 113 may be used to stop the transmission member 535 from abutting against the abutment member 531 when the transmission member 535 rotates. In addition, it should be noted that the present application is not limited to this, in other embodiments, the locking assembly 53 may only include the abutment member 531, in this case, the upper end of the abutment member 531 is connected to the first elastic member 51, the first elastic member 51 drives the abutment member 531 to descend so as to be able to abut against the wheel 30, and the upper end of the abutment member 531 may be further attracted and driven by the electromagnet 55 after being energized so as to be away from the wheel 30.
Referring to fig. 4, fig. 5 and fig. 6, in an embodiment of the present invention, the abutting member 531 includes a pressing plate 532 and a connecting plate 533, the pressing plate 532 is disposed in an arc shape, and an inward concave arc surface of the pressing plate 532 is used for abutting against the wheel 30; the connecting plate 533 is disposed on the rack 10 in a liftable manner, the connecting plate 533 has two opposite ends, one end of the connecting plate 533 is connected to the pressing plate 532, and the other end is connected to the end of the transmission member 535 away from the first elastic member 51.
It can be understood that the abutting part 531 abuts against the wheel 30 through the arc-shaped pressing plate 532, so that the abutting part 531 can be well attached to the wheel 30, the attaching area of the abutting part 531 and the wheel 30 is increased, the abutting part 531 is favorable for improving the abutting limiting effect of the abutting part 531 on the wheel 30, and the stable brake state of the anesthesia machine is ensured. By abutting the connecting plate 533 and the transmission member 535, the connecting plate 533 and the transmission member 535 have a relatively flat abutting surface to ensure the stability of the abutting. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the abutting member 531 only includes the connecting plate 533, and the lower end of the connecting plate 533 is formed with a concave surface, so that the connecting plate 533 is directly abutted to the wheel 30 through the concave surface.
Referring to fig. 4, fig. 5 and fig. 6, in an embodiment of the present invention, the abutting member 531 further includes an abutting plate 534, the abutting plate 534 is connected to one end of the connecting plate 533 far away from the pressing plate 532, a projection of the abutting plate 534 on a horizontal plane covers a projection of the connecting plate 533 on the horizontal plane, and a surface of the abutting plate 534 far away from the connecting plate 533 is used for being abutted and driven by one end of the transmission member 535 far away from the first elastic member 51.
It can be understood that the abutting member 531 performs abutting transmission through the abutting plate 534 with a relatively large area and the transmission member 535, and the possibility of the disengagement between the abutting plate 534 and the transmission member 535 can be reduced, so as to be beneficial to ensuring that one end of the transmission member 535, which is far away from the first elastic member 51, stably abuts against the upper surface of the abutting plate 534, so that the pressing plate 532 of the abutting member 531 can stably abut against the wheel 30 to ensure normal and stable braking of the wheel 30. In order to increase the strength of the abutment member 531 and reduce the possibility of damage, the pressing plate 532, the connecting plate 533 and the abutting plate 534 of the abutment member 531 may be integrally provided to increase the strength of the joints therebetween and reduce the possibility of breakage. Meanwhile, the arrangement also enables several of the supporting parts to be manufactured through integral forming, simplifies the processing technology and improves the production efficiency of the supporting part 531.
Referring to fig. 4, 5 and 6, in an embodiment of the invention, the locking assembly 53 further includes a second elastic member 539, and the second elastic member 539 elastically abuts against the frame 10 and the abutting plate 534 and drives the abutting plate 534 to ascend.
It can be understood that, when the electromagnet 55 after being powered on drives the transmission member 535 in an adsorbing manner, the transmission member 535 may rotate to separate from the abutting plate 534 of the abutting member 531, and at this time, the second elastic member 539 may drive the abutting plate 534 to ascend, so that the pressing plate 532 of the abutting member 531 is not abutted to the wheel 30, and thus the wheel 30 may rotate smoothly after the anesthesia apparatus is unlocked, so as to facilitate the pushing of the medical care personnel. The second elastic member 539 may be a spring, plastic, or other plastic member with a certain elasticity.
Referring to fig. 4 or fig. 6, in an embodiment of the present invention, a distance between an end of the transmission member 535 close to the first elastic member 51 and a rotation axis of the transmission member 535 is greater than a distance between an end of the transmission member 535 for abutting against the driving abutment member 531 and the rotation axis of the transmission member 535.
It will be appreciated that the relatively long distance provided by the transmission member 535 near the end of the first elastic member 51 allows the transmission member 535 to be driven with a small force near the first elastic member 51 while ensuring that the end of the transmission near the abutment member 531 can have a large force to abut it. Thus, the transmission member 535 is driven by a small force to stably abut against the abutting member 531, so that the abutting member 531 stably abuts against the limit wheel 30, thereby reducing the performance requirements on the first elastic member 51 and the electromagnet 55 and being beneficial to reducing the manufacturing cost of the anesthesia machine. Of course, the present application is not limited thereto, and in other embodiments, the distance between the end of the transmission member 535 close to the first elastic member 51 and the rotation axis of the transmission member 535 is equal to the distance between the end of the transmission member 535 for abutting against the driving abutment member 531 and the rotation axis of the transmission member 535.
Referring to fig. 4 or fig. 6, in an embodiment of the present invention, a portion of the transmission member 535 between an end of the transmission member 535 close to the first elastic member 51 and a rotation axis of the transmission member 535 is defined as a first segment 536, a portion of the transmission member 535 between an end of the driving abutment member 531 and the rotation axis of the transmission member 535 is defined as a second segment 537, the first segment 536 and the second segment 537 are disposed at an obtuse angle, and an opening of an included angle formed by the first segment 536 and the second segment 537 is disposed toward the first elastic member 51.
It will be appreciated that the transmission member 535 is formed by the first segment 536 and the second segment 537 which are angularly disposed, so that the overall structure of the transmission member 535 is relatively small, thereby facilitating a more compact distribution of the first resilient member 51, the transmission member 535, and the electromagnet 55. Meanwhile, the arrangement enables the first segment 536 to be vertical after the electromagnet 55 is adsorbed after being powered on, and to be tightly attached to the surface of the electromagnet 55, so that the stability of the electromagnet 55 on the adsorption is ensured.
Referring to fig. 4 or fig. 6, in an embodiment of the present invention, a guide surface 538 is disposed at an end of the transmission member 535 away from the first elastic member 51, and when the first elastic member 51 drives the transmission member 535 to rotate, the guide surface 538 guides the end of the transmission member 535 away from the first elastic member 51 to rotate to an upper surface of the abutting member 531.

It can be understood that, the abutting piece 531 of the locking component 53 abuts against the rotating shaft 31 of the wheel 30 for braking limitation, and the rotating shaft 31 is relatively small, so that the inward concave arc surface of the pressing plate 532 of the abutting piece 531 can conveniently wrap and abut against the rotating shaft 31 sufficiently, and the abutting piece 531 does not need to be relatively large in structural arrangement, so that the manufacturing cost is reduced. Meanwhile, the brake limiting is carried out by abutting against the rotating shaft 31, so that the corresponding abrasion to the rotating wheel 33 is avoided, and the service life of the wheel 30 is ensured.
Referring to fig. 1 to 5, in an embodiment of the present invention, a plurality of mounting seats 111 are disposed at the bottom of the frame 10, one mounting seat 111 is disposed corresponding to one wheel 30 and one brake mechanism 50, a mounting cavity 111a is formed in each mounting seat 111, and the rotating shaft 31 of each wheel 30 passes through the mounting cavity 111a of the mounting seat 111 corresponding to the wheel 30; the first elastic member 51 and the locking assembly 53 of each brake mechanism 50 are disposed in the mounting cavity 111a of the mounting seat 111 corresponding to the brake mechanism 50, and the electromagnet 55 is disposed outside the mounting seat 111.
It can be understood that, by arranging the first elastic element 51 and the locking assembly 53 in the mounting cavity 111a of the mounting seat 111 corresponding to the braking mechanism 50, the possibility that the first elastic element 51 and the locking assembly 53 are collided by an obstacle on the ground can be reduced, thereby being beneficial to ensuring that the first elastic element 51 and the locking assembly 53 work normally and stably to perform normal and stable braking limiting on the wheel 30. By providing the electromagnet 55 outside the mounting seat 111, the transmission member 535 of the locking assembly 53 can be provided with a relatively large rotation space in the mounting cavity 111 a. In order to facilitate the attraction of the electromagnet 55 to the transmission member 535 of the locking assembly 53, the mounting seat 111 may be provided with an allowance at a position corresponding to a position between the transmission member 535 and the electromagnet 55. In other embodiments, when the mounting cavity 111a of the mounting seat 111 has a relatively large space, the electromagnet 55 may be further provided in the mounting cavity 111 a. Wherein, the mounting seat 111 may be arranged at the bottom of the base 11 of the rack 10, so as to be more compactly distributed on the base 11. The transmission member 535 may be disposed on the wall of the mounting cavity 111a of the mounting seat 111 at the position of the stopper 113 for limiting the rotation driven by the first elastic member 51.

It can be understood that the pressure sensor 90 can detect whether the holding area 13a is pressed, that is, when the medical staff places the hands in the holding area 13a of the rack 10 and the pressure sensor 90 detects the pushing pressure of the medical staff, the pressure signal can be transmitted to the controller 70, and the controller 70 controls the electromagnet 55 to be electrified according to the pressure signal to realize the automatic braking and unlocking of the anesthesia machine. When the medical staff separates the hands from the holding area 13a of the frame 10 and the pressure sensor 90 does not detect the pressure, the controller 70 controls the electromagnet 55 to be powered off to realize the automatic braking limit of the anesthesia machine. So make this anesthesia machine just automatic brake spacing when not being promoted by medical personnel, and only carry out the brake unblock when being promoted by medical personnel to further improve this anesthesia machine convenience of using and reduced medical personnel's intensity of labour. Meanwhile, the safety of the anesthesia machine in the use process is improved. The damage to the brake system of the anesthesia machine caused by the direct pushing of the anesthesia machine when the anesthesia machine is in an unlocking state due to the fact that medical staff forget to unlock the anesthesia machine is avoided. Wherein, the holding area 13a is formed on the body 13 of the frame 10.
