Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The anesthesia machine provided by the embodiment of the invention comprises an assembly connecting seat which is used for assembling the assembly. It will be appreciated that in some embodiments, as shown in figures 1 and 2, the component may be an anesthetic vaporizer 20 and, correspondingly, the component connection mount may be an anesthetic vaporizer connection mount 10. Of course, the component may also be an anesthesia machine plug-in module or the like. The structure of the connecting base of the anesthetic vaporizer will be further described below by taking the connecting base 10 as an example.

The anesthetic vaporizer connecting base 10 includes a housing 11, a connector 12, and a connector protector 13.

As shown in fig. 2 and 3, the interface 12 is disposed in the housing 11, and the housing 11 is provided with an insertion hole 111 opposite to the interface 12. The interface protection device 13 can selectively expose the insertion hole 111 out of the interface 12 or shield the interface 12 by the interface protection device 13 according to the assembling state of the anesthetic vaporizer 20 and the anesthetic vaporizer connecting base 10, and it should be noted that when the interface 12 is shielded, the interface 12 will not be exposed to the outside and be contaminated by dust or germs.

In the above embodiment, the number of the interfaces 12 and the jacks 111 is not limited, and may be one or more.

As shown in fig. 1, the housing 11 has a plurality of insertion holes 111, namely, a first insertion hole 111a, a second insertion hole 111b, a third insertion hole 111c and a fourth insertion hole 111 d. It is understood that the shape of the plurality of insertion holes 111 may be the same, and the insertion holes 111 may be configured into different shapes according to actual needs. Correspondingly, as shown in fig. 2 and 3, the insertion hole 111 is provided at a position where the housing 11 and the ports 12 are opposite to each other, that is, the number and types of the ports 12 may be configured according to actual needs, in fig. 2 and 3, there are a first port 12a, a second port 12b, a third port 12c, and a fourth port 12d, respectively, and these ports 12 may be air path ports for ventilation or electric circuit ports for energization. It is understood that the air passage interface on the connecting seat of the assembly is capable of interfacing with the assembly, such as an atomizing interface, a gas sampling interface or an anesthetic vaporizer interface, and is not limited herein.

The interface protection device 13 includes a blocking member 131, a drive mechanism, and a trigger mechanism 135. The blocking member 131 can move between a first position and a second position under the action of the driving mechanism; the trigger mechanism 135 is used to detect the loading and unloading of the anesthetic vaporizer 20. It should be noted that the blocking member may be disposed on the housing 11, or may be disposed between the housing 11 and the interface 12. In the present embodiment, when the stopper 131 is moved to the first position, the insertion hole 111 exposes the interface 12; when the blocking member 131 moves to the second position, the blocking member 131 blocks the interface 12.

In the above embodiment, the driving mechanism is triggered to move the blocking member to the first position when the triggering mechanism detects the fitting of the anesthetic vaporizer 20, and the driving mechanism is triggered to move the blocking member to the second position when the triggering mechanism detects the unloading of the anesthetic vaporizer 20. That is, when the trigger mechanism detects the assembling action of the anesthetic vaporizer 20, the trigger mechanism will trigger the driving mechanism to move the blocking member to the first position, the insertion hole 111 exposes the interface 12, and the connector of the anesthetic vaporizer 20 can pass through the insertion hole 111 to connect with the interface 12, so as to connect the electric circuit and/or the air circuit; correspondingly, when the trigger mechanism detects the unloading action of the anesthetic vaporizer 20, the driving mechanism is triggered, and when the blocking piece 131 moves to the second position, the blocking piece 131 blocks the interface 12, so that the interface 12 is prevented from being exposed to the outside when not connected with the anesthetic vaporizer 20, the interface 12 is well protected, and the interface 12 is prevented from being contaminated by dust or germs to harm a patient.

The blocking member 131 can also block the interface 12 from the outside by blocking the insertion hole 111. The stopper 131 is provided on the outside of the housing 11, for example. Therefore, when the anesthetic vaporizer 20 is removed from the anesthetic vaporizer attaching base 10, the driving mechanism drives the blocking member 131 to move to the second position, and the blocking member 131 seals the insertion hole 111, thereby preventing dust or germs from entering the housing 11 from the insertion hole 111 to contaminate the mouthpiece 12 and infect patients.

It should be noted that the driving block 131 can be moved between the first position and the second position by using a mechanical structure as the driving force, i.e. the force applied to the driving mechanism by the trigger mechanism 135 when the anesthetic vaporizer 20 is assembled to the anesthetic vaporizer assembling unit 10. Of course, an electric structure can also be used as a driving force, that is, the anesthetic vaporizer 20 is not required to be assembled to provide power, but the corresponding electric structure is triggered to provide power for the driving mechanism to move the blocking member 131 according to the assembling and disassembling actions of the anesthetic vaporizer 20 and the anesthetic vaporizer connecting seat 10.

The driving mechanism comprises a driving component and a resetting component, and when the triggering mechanism detects the assembling action of the anesthetic vaporizer 20, the driving component drives the blocking piece to move to the first position; when the trigger mechanism detects the unloading of the anesthetic vaporizer 20, the reset assembly actuates the blocking member to move to the second position. During assembly of the anesthetic vaporizer 10 to the anesthetic vaporizer attachment base, the anesthetic vaporizer 20 can exert a force on the drive assembly via the trigger mechanism to move the blocking member 131 to the first position by the drive assembly. When the anesthetic vaporizer 20 is removed, the reset assembly can restore the blocking member 131 from the first position to the second position due to the absence of the force applied to the drive assembly by the anesthetic vaporizer 20. It can be seen that during movement of the barrier 131 to the first position, the reset assembly is storing energy to release the stored energy to return the barrier 131 to the second position when the anesthetic vaporizer 20 is removed.

The drive assembly includes a connecting member 132 and a transmission member 133. One end 132a of the connecting member 132 is connected to the blocking member 131, and the other end 132b is hinged to the transmission member 133. The transmission member 133 drives the blocking member 131 to move between the first position and the second position through the connecting member 132. It should be noted that the transmission member 133 can move relative to the housing 11, for example, the transmission member 133 can be rotatably disposed in the housing 11, and the hinge point of the connecting member 132 and the transmission member 133 is offset from the rotation axis of the transmission member 133 relative to the housing 11; so that the transmission member 133 can drive the blocking member 131 to move between the first position and the second position through the connecting member 132 when the transmission member 133 rotates relative to the housing 11. In addition, the driving member 133 may be provided with a driving force by a motor or an electromagnet.

In other embodiments, the transmission member 133 may be in a swing link structure, or may also be in a cam structure, and when the hinge point between the connection member 132 and the transmission member 133 deviates from the rotation axis of the transmission member 133, the swing link structure and the cam structure can both achieve the reciprocating motion of the connection member 132, so as to drive the blocking member 131 to move between the first position and the second position. It will be appreciated that the drive assembly may also be a linkage mechanism, a timing belt, a gear or a chain.

It should be noted that the triggering mechanism may be electronically triggered, such as a travel switch, a photoelectric sensor, or a hall sensor. The travel switch realizes trigger detection through pressing, the photoelectric sensor realizes detection through shielding, and the Hall sensor realizes detection through magnetic field change.

Specifically, when the trigger mechanism adopts a travel switch, in the process that the anesthetic vaporizer 20 is assembled to the anesthetic vaporizer connecting seat 10, the travel switch is pressed until the state of the travel switch is changed, and then the drive mechanism is triggered to move the blocking piece 131 to the first position; accordingly, in the process of removing the anesthetic vaporizer 20, the anesthetic vaporizer 20 also loses the pressing effect on the travel switch, and when the state of the travel switch is switched, the driving mechanism is triggered to move, so that the blocking member 131 is moved to the second position.

It will be appreciated that when the triggering mechanism employs a photoelectric sensor, the blocking state of the photoelectric sensor changes during the process of assembling and disassembling the anesthetic vaporizer 20, and the driving mechanism is triggered to move the blocking member 131 between the first position and the second position.

Since the hall sensor detects the anesthetic vaporizer 20 by changing the magnetic field, when the trigger mechanism detects the assembling and disassembling of the anesthetic vaporizer 20 by using the hall sensor, the magnetic field changes during the assembling and disassembling of the anesthetic vaporizer 20, and the state of the hall sensor is changed. Therefore, by changing the state of the hall sensor, the driving mechanism can be triggered to act, and the corresponding driving blocking member 131 moves to the first position and the second position.

Specifically, as shown in fig. 2 and 3, the triggering mechanism includes a pressing member 135 disposed on the transmission member 133, and the pressing member 135 at least partially protrudes out of the housing 11, so that when the anesthetic vaporizer 20 is assembled to the anesthetic vaporizer connecting unit 10, the anesthetic vaporizer 20 drives the transmission member 133 to rotate relative to the housing 11 through the pressing member 135, so that the transmission member 133 drives the connecting member 132 to move, and the blocking member 131 connected to the connecting member 132 moves between the first position and the second position.

Specifically, when the anesthetic vaporizer 20 is assembled, the anesthetic vaporizer 20 presses the pressing member 135 by its own weight, so that the pressing member 135 moves downward (in the direction of arrow D in fig. 3), and the transmission member 133 rotates relative to the housing 11; at this time, the link member 132 connected to the transmission member 133 moves the blocking member 131 from the second position to the first position.

It should be noted that, in the above embodiment, the sliding sleeve 112 is disposed on the housing 11, and the pressing member 135 is movably inserted into the sliding sleeve 112, so that when the anesthetic vaporizer 20 is placed on the pressing member 135, the pressing member 135 moves up and down along the sliding sleeve 112 to stably press the transmission member 133. Furthermore, the transmission element 133 can be connected to the housing 11 by means of the connecting piece 114. The abutting portion 113 is disposed in the housing 11, and the transmission member 133 keeps abutting against the abutting portion 113 under the action of the reset component, that is, under the limit action of the abutting portion 133 on the transmission member 133, the transmission member 133 does not rotate relative to the housing 11 after abutting against the supporting portion 113, and since the transmission member 133 is connected to the connecting member 132, the connecting member 132 can keep the blocking member 131 at the first position.

It should be noted that the pressing member 135 may be disposed at the bottom of the anesthetic vaporizer connecting base 10, and the portion of the pressing member 135 extending out of the housing 11 is provided with a wedge-shaped slope 135a, so that when the anesthetic vaporizer 20 is pushed toward the interface 12 (in the direction of arrow P in fig. 3), the bottom of the anesthetic vaporizer 20 presses against and slides along the wedge-shaped slope 135 a. The wedge-shaped ramp 135a makes it possible for the anesthetic vaporizer 20 to be pressed in a translatory manner gradually against the pressing piece 135. It will be appreciated that the pressing element 135 may be arranged at a reasonable distance from the interface 12, such that, when the anesthetic vaporizer 20 is slid on the wedge-shaped slope 135a of the pressing element 135 adjacent to the interface 12, the stop 131 is completely moved away to expose the interface 12 for connection with the anesthetic vaporizer 20.

The end of the pressing member 135 away from the tapered surface 135a is provided with a protrusion 135b, and the protrusion 135b abuts against the transmission member 133, so that the pressing member 135 and the transmission member 133 are in point contact, and when the pressing member 135 presses the transmission member 133 to rotate relative to the housing 11, the contact surface between the protrusion 135b and the transmission member 133 is small, and the rotation effect of the transmission member 133 is not limited. Furthermore, the points of action of the pressing member 135 on the transmission member 133 are all concentrated at the nose 135b, so that, during the rotation of the transmission member 133 with respect to the housing 11, the points of action of the pressing member 135 on the transmission member 133 are substantially the same, making the rotation of the transmission member 133 with respect to the housing 11 more stable. The raised head 135b is in spherical contact with the transmission piece 133, so that the compressive strength of the raised head 135b is improved, and abrasion caused by long-term rotation between the raised head and the transmission piece 133 is avoided.

In other embodiments, the pressing element 135 may be further disposed on the vertical sidewall of the anesthetic vaporizer connecting base 10 to press the pressing element 135 when the anesthetic vaporizer 10 pushes the interface 12, so as to move the blocking element 131 to the second state, which is not described in detail herein.

With reference to fig. 1 and 4, the anesthetic vaporizer attaching base 10 is provided with a guide structure 115 so that the anesthetic vaporizer 20 can be pushed toward the interface 12 along the guide structure 115, and the joint of the anesthetic vaporizer 20 is easily aligned with the interface 12 to achieve a quick assembly of the rapid anesthetic vaporizer 20. An operation indication area 1152 is further provided on the guide structure 115, specifically, the operation indication area 1152 shows the advancing direction of the anesthetic vaporizer 20 along the guide structure 115 when the anesthetic vaporizer 20 is assembled, and a side edge 1151 is provided at the end of the guide structure 115 close to the interface 12, and accordingly, the bottom of the anesthetic vaporizer 20 is provided with a guide groove matching with the side edge 1151 on the guide structure 115, so that the guide groove slides along the side edge 1151 when the anesthetic vaporizer 20 is pushed toward the interface 12 along the guide structure 115, that is, the matching of the side edge 1151 and the guide groove limits the movement of the anesthetic vaporizer 20 in the vertical direction, and thus, when the wedge-shaped slope of the pressing member 135 has a force pressing the anesthetic vaporizer 20 upwards, the matching of the side edge 1151 and the guide groove correspondingly exerts a reaction force on the anesthetic vaporizer 20 downwards (in the direction of arrow D in fig. 3). Thus, even when the self-weight of the anesthetic vaporizer 20 is not sufficient to overcome the force of the reset assembly acting on the transmission member 133, the medical staff is not required to press the pressing member 135 downward, and only in the direction of the mouthpiece 12 (the direction of arrow P in fig. 3), the anesthetic vaporizer 20 can slide along the wedge-shaped slope 135a of the pressing member 135 and drive the transmission member 133 to rotate relative to the housing 11, thereby moving the blocking member 131 to the first position.

The reset assembly may adopt an elastic element, as shown in fig. 2 and 3, the elastic element is a tension spring 134, and two ends of the tension spring 134 are respectively connected with the housing 11 and the transmission member 133; when the trigger mechanism detects the anesthetic vaporizer 20 being assembled, the driving member 133 moves relative to the housing 11 to pull the tension spring 134, and when the anesthetic vaporizer trigger mechanism detects the anesthetic vaporizer being unloaded, the tension spring 134 contracts to drive the driving member 133 to move relative to the housing 11 to move the blocking member 131 to the second position.

It should be noted that the anesthetic vaporizer can not only drive the blocking member 131 to move from the first position to the second position by the resetting assembly to complete the resetting action of the blocking member 131, but also can utilize the reverse movement of the driving assembly to achieve the resetting action. That is, the driving mechanism not only can drive the blocking member 131 to move to the first position when the anesthetic vaporizer 20 is assembled, but also can expose the jack 111 out of the interface 12 for the connection of the anesthetic vaporizer 20; furthermore, during unloading of the anesthetic vaporizer 20, the driving mechanism may also be moved in the opposite direction, so as to return the blocking member 131 from the first position to the second position, i.e. to shield the interface 12, i.e. to isolate the interface 12 from the outside, thereby preventing the interface 12 from being contaminated by dust or germs from the outside and thus harming the patient.

The blocking member 131 can move between the first position and the second position by means of translation such as up-and-down movement or left-and-right movement; the shielding interface 12 may also be realized by a relative rotation between the blocking member 131 and the housing 11. For example: the blocking member 131 is rotatably connected to the housing 11, and when the blocking member 131 is in the first position, the blocking member 131 has a through hole 131 opposite to the insertion hole 111, that is, when the blocking member 131 is in the first position, the blocking member 131 does not block the insertion hole 111, so that the interface 12 can be exposed through the insertion hole 111 to connect to a corresponding connector on the anesthetic vaporizer 20. When the blocking member 131 is rotated relative to the housing 11 to be in the second position, the through hole 131 of the blocking member 131 is staggered with respect to the insertion hole 111 to block the insertion hole 111, so that when the mouthpiece 12 is not connected to the anesthetic vaporizer 20, the blocking member 131 is blocked between the mouthpiece 12 and the insertion hole 111 to prevent external dust or germs from being attached to the mouthpiece 12. Of course, in this embodiment, the stopper 131 may be moved in a translational manner with respect to the housing 11, so that the insertion hole 111 is selectively opposed to or displaced from the through hole 131.

It should be noted that, in some specific applications, the number and the position of the through holes 131 may be determined according to the number and the position of the insertion holes 111, taking the structure shown in fig. 2 and 3 as an example, the housing 11 is provided with a first insertion hole 111a, a second insertion hole 111b, a third insertion hole 111c and a fourth insertion hole 111d, when the blocking member 131 moves to the first position, as long as the top end of the blocking member 131 is lower than the first insertion hole 111a, only the first through hole 131a, the second through hole 131b and the third through hole 131c which are respectively opposite to the second insertion hole 111b, the third insertion hole 111c and the fourth insertion hole 111d need to be provided on the blocking member 131, and when the blocking member 131 moves upwards to the second position, because the through holes 131 and the interface 12 are staggered with each other, the blocking member 131 blocks at the interface 12, thereby protecting the interface 12.

In other embodiments, the blocking member 131 is provided with a slit or the like for selectively communicating the insertion hole 111 and the port 12. In addition, the blocking member 131 may be formed by a plurality of plates disposed at intervals, so that when the blocking member moves between the first position and the second position, the plurality of plates disposed at intervals open or block the insertion hole 111; specifically, in the first position, the space between the plates allows the mouthpiece 12 to be exposed from the receptacle 111, so that the connector of the anesthetic vaporizer 20 can be connected to the mouthpiece 12 through the receptacle 111; accordingly, in the second position, the insertion hole 111 is shielded by the plate, so as to prevent the interface 12 from being exposed from the insertion hole 111 when the anesthetic vaporizer 20 is not assembled to the anesthetic vaporizer attaching base 10, thereby preventing the interface 12 from being contaminated by external dust or germs.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
