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. The term "and/or" as used herein 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 the component connecting seat for assembling the component. It will be appreciated that in some specific applications, as shown in fig. 1 and 2, the component may be an anesthetic vaporizer 20 and, correspondingly, the component connection may be an anesthetic vaporizer connection 10. Of course, the component may also be an anesthesia machine insert module or the like. The structure of the component connection socket will be further described with reference to the anesthetic vaporizer connection socket 10.
The anesthetic vaporizer connector 10 includes a housing 11, an interface 12, and an interface protection device 13.
As shown in fig. 2 and 3, the interface 12 is disposed in the housing 11, and a jack 111 opposite to the interface 12 is formed in the housing 11. The interface protection device 13 can selectively expose the jack 111 to the interface 12 or cover the interface 12 by the interface protection device 13 according to the assembled state of the anesthetic vaporizer 20 and the anesthetic vaporizer connecting seat 10, and it should be noted that when the interface 12 is covered, the interface 12 is not exposed to be contaminated with dust or germs.
In the above embodiment, the number of the interfaces 12 and the insertion holes 111 is not limited, and may be one or a plurality of.
As shown in fig. 1, the housing 11 has a plurality of insertion holes 111, which are a first insertion hole 111a, a second insertion hole 111b, a third insertion hole 111c, and a fourth insertion hole 111d, respectively. It is understood that the shapes of the plurality of insertion holes 111 may be the same, or may be configured into insertion holes 111 of different shapes according to actual needs. Accordingly, as shown in fig. 2 and 3, the insertion hole 111 is provided at a position where the housing 11 faces the interface 12, that is, the number and types of the interfaces 12 may be configured according to actual needs, and in fig. 2 and 3, the first interface 12a, the second interface 12b, the third interface 12c, and the fourth interface 12d are provided, respectively, and these interfaces 12 may be air path interfaces for ventilation or circuit interfaces for energization. It will be appreciated that the air passage interface on the module connection base may interface with the module, such as an aerosol interface, a gas sampling interface, or an anesthetic vaporizer interface, without limitation.
The interface protection device 13 includes a blocking member 131, a drive mechanism, and a trigger mechanism 135. The blocking member 131 is movable between a first position and a second position under the influence of the drive mechanism; the trigger mechanism 135 is used to detect the assembly and disassembly actions of the anesthetic vaporizer 20. The blocking member may be provided on the housing 11, or may be provided between the housing 11 and the interface 12. In this embodiment, when the blocking member 131 is moved to the first position, the insertion hole 111 exposes the interface 12; when the blocking member 131 is moved to the second position, the blocking member 131 obscures 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 assembling action 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 action of the anesthetic vaporizer 20. That is, when the trigger mechanism detects the assembly of the anesthetic vaporizer 20, the trigger mechanism will trigger the driving mechanism to move the blocking member to the first position, the jack 111 exposes the interface 12, and the connector of the anesthetic vaporizer 20 may be connected to the interface 12 through the jack 111 to complete the electrical circuit and/or the air circuit; correspondingly, when the triggering mechanism detects the unloading action of the anesthetic vaporizer 20, the driving mechanism is triggered, and when the blocking member 131 moves to the second position, the blocking member 131 shields the interface 12, so that the interface 12 is prevented from being exposed to the outside when the interface 12 is not connected with the anesthetic vaporizer 20, the interface 12 is well protected, and the interface 12 is prevented from being contaminated with dust or germs to harm a patient.
The blocking member 131 may also isolate the interface 12 from the outside by shielding the insertion hole 111. For example, the stopper 131 is provided outside the housing 11. Thus, when the anesthetic vaporizer 20 is removed from the anesthetic vaporizer attachment base 10, the drive mechanism drives the blocking member 131 to the second position, the blocking member 131 seals the receptacle 111, and thereby prevents dust or germs from entering the housing 11 from the receptacle 111 and contaminating the mouthpiece 12, and infecting a patient.
It should be noted that, the movement of the driving blocking member 131 between the first position and the second position may use a mechanical structure as a driving force, that is, a force applied to the driving mechanism by the trigger mechanism 135 when the anesthetic vaporizer 20 is assembled to the anesthetic vaporizer connecting seat 10. Of course, an electric structure can be adopted as the driving force, that is, the assembly of the anesthetic vaporizer 20 is not needed 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 assembly and unloading 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 assembly behavior of the anesthetic vaporizer 20, the driving component drives the blocking piece to move to the first position; when the trigger mechanism detects an unloading event of the anesthetic vaporizer 20, the reset assembly drives the barrier to move to the second position. During assembly of the anesthetic vaporizer 20 to the anesthetic vaporizer attachment base 10, the anesthetic vaporizer 20 may exert a force on the drive assembly via the trigger mechanism, thereby moving the blocking member 131 to the first position via the drive assembly. When the anesthetic vaporizer 20 is removed, the reset assembly may then return the stop 131 from the first position to the second position due to the force exerted by the anesthetic vaporizer 20 on the drive assembly. It can be seen that during movement of the blocking member 131 to the first position, the reset assembly stores energy to release the stored energy to restore the blocking member 131 to the second position when the anesthetic vaporizer 20 is removed.
The drive assembly includes a connector 132 and a transmission 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 driving 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 may move relative to the housing 11, for example, the transmission member 133 may be rotatably disposed in the housing 11, and a hinge point of the connection member 132 and the transmission member 133 may be offset from a rotation axis of rotation of the transmission member 133 relative to the housing 11; so that the transmission member 133 can drive the blocking member 131 between the first position and the second position via the connection member 132 when the transmission member 133 rotates relative to the housing 11. In addition, the transmission member 133 may be provided with a driving force by a motor or an electromagnet.
In other embodiments, the transmission member 133 may adopt a swing link structure or a cam structure, and when the hinge point of 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 implement 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, timing belt, gear or chain.
It should be noted that the triggering mechanism may be electronically triggered, for example, by a travel switch, a photoelectric sensor, or a hall sensor. The travel switch realizes triggering detection by pressing, the photoelectric sensor realizes detection by shielding, and the Hall sensor realizes detection by magnetic field change.
Specifically, when the trigger mechanism adopts a travel switch, in the process of assembling the anesthetic vaporizer 20 to the anesthetic vaporizer connecting seat 10, the travel switch is pressed until the state of the travel switch changes, so that the trigger driving mechanism moves the blocking member 131 to the first position; accordingly, during the process of removing the anesthetic vaporizer 20, the anesthetic vaporizer 20 will lose the pressing action on the travel switch, and further trigger the driving mechanism to act to move the blocking member 131 to the second position when the state of the travel switch is switched.
It will be appreciated that when the trigger mechanism employs a photoelectric sensor, the shielding state of the photoelectric sensor will change during assembly and disassembly of the anesthetic vaporizer 20, thereby triggering the drive mechanism to move the barrier 131 between the first and second positions.
Because the hall sensor is used for detecting through magnetic field change, when the triggering mechanism adopts the hall sensor to detect the assembling and unloading actions of the anesthetic vaporizer 20, the magnetic field change is caused in the process of assembling and unloading the anesthetic vaporizer 20, and the state of the hall sensor is changed. Thus, by a change of state of the hall sensor, the actuation of the driving mechanism can be triggered, the respective driving stops 131 being moved to the first and second positions.
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 extends at least partially out of the housing 11, so that when the anesthetic vaporizer 20 is assembled to the anesthetic vaporizer connecting seat 10, the anesthetic vaporizer 20 drives the transmission member 133 to rotate relative to the housing 11 via 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 itself is pressed against the pressing member 135 by gravity, so that the pressing member 135 moves downward (in the direction of arrow D in fig. 3), and the transmission member 133 is rotated with respect to the housing 11; at this time, the link 132 connected to the transmission member 133 moves the blocking member 131 from the second position to the first position.
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. In addition, the transmission element 133 can be rotatably connected to the housing 11 via the connecting piece 114. The housing 11 is provided with a supporting portion 113, the transmission member 133 is kept against the supporting portion 113 under the action of the reset assembly, that is, the transmission member 133 does not continue to rotate relative to the housing 11 after being against the supporting portion 113 under the limiting action of the supporting portion 133 on the transmission member 133, and the connection member 132 can keep the blocking member 131 at the first position because the transmission member 133 is connected with the connection member 132.
It should be noted that the pressing member 135 may be disposed at the bottom of the anesthetic vaporizer connecting seat 10, and a 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 (along the arrow P in fig. 3), the bottom of the anesthetic vaporizer 20 is pressed against and slides along the wedge-shaped slope 135 a. The wedge-shaped ramp 135a allows the anesthetic vaporizer 20 to gradually press against the pressing member 135 in a translational manner. It will be appreciated that the compression member 135 may be positioned at a reasonable distance from the hub 12 such that, as the anesthetic vaporizer 20 slides over the wedge-shaped ramp 135a of the compression member 135 to adjacent the hub 12, the stop 131 is completely clear exposing the hub 12 for connection with the anesthetic vaporizer 20.
The end of the pressing piece 135 far away from the wedge-shaped slope surface 135a is provided with a protruding head 135b, and the protruding head 135b is abutted against the transmission piece 133, so that the pressing piece 135 is in point contact with the transmission piece 133, when the pressing piece 135 presses the transmission piece 133 to rotate relative to the shell 11, the contact surface between the protruding head 135b and the transmission piece 133 is small, and the rotation effect of the transmission piece 133 is not limited. In addition, the points of action of the pressing member 135 on the transmission member 133 are concentrated at the boss 135b, and thus, the points of action of the pressing member 135 on the transmission member 133 are substantially the same during rotation of the transmission member 133 relative to the housing 11, so that the transmission member 133 rotates more stably relative to the housing 11. The convex head 135b is in spherical contact with the transmission member 133, so that the compressive strength of the convex head 135b is improved, and abrasion caused by rotation between the convex head and the transmission member 133 for a long time is avoided.
In other embodiments, the pressing member 135 may be further disposed on a vertical sidewall of the anesthetic vaporizer connecting seat 10, so as to press the pressing member 135 when the anesthetic vaporizer 10 is pushed toward the interface 12, so that the blocking member 131 moves to the second state, which will not be described in detail herein.
Referring to fig. 1 and 4, the anesthetic vaporizer connecting seat 10 is provided with a guiding structure 115, so that the anesthetic vaporizer 20 can be pushed toward the interface 12 along the guiding structure 115, and the connector of the anesthetic vaporizer 20 is relatively easy to align with the interface 12, so as to realize rapid assembly of the anesthetic vaporizer 20. An operation indication area 1152 is further provided on the guide structure 115, specifically, the operation indication area 1152 shows a pushing direction along the guide structure 115 when the anesthetic vaporizer 20 is assembled, and in addition, a side edge 1151 is provided on an end of the guide structure 115 near the interface 12, and correspondingly, a guide groove matched with the side edge 1151 on the guide structure 115 is provided on the bottom of the anesthetic vaporizer 20, so that when the anesthetic vaporizer 20 is pushed toward the interface 12 along the guide structure 115, the guide groove slides along the side edge 1151, that is, the cooperation of the side edge 1151 and the guide groove limits the movement of the anesthetic vaporizer 20 in the vertical direction, so that when the wedge-shaped inclined surface of the pressing member 135 has a force for pressing the anesthetic vaporizer 20 upwards, the cooperation of the side edge 1151 and the guide groove correspondingly applies a downward (arrow D direction in fig. 3) reaction force on the anesthetic vaporizer 20. Thus, even when the gravity of the anesthetic vaporizer 20 is insufficient 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 forcefully, and only the direction of the interface 12 (arrow P direction in fig. 3) is required, so that 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 realizing the movement of the blocking member 131 to the first position.
The reset component can adopt elastic elements, as shown in fig. 2 and 3, the elastic elements are tension springs 134, and two ends of the tension springs 134 are respectively connected with the shell 11 and the transmission piece 133; when the trigger mechanism detects the anesthetic vaporizer 20 to be assembled, the transmission member 133 moves relative to the housing 11 to stretch the tension spring 134, and when the anesthetic vaporizer trigger mechanism detects the anesthetic vaporizer unloading, the tension spring 134 contracts to drive the transmission 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 may not only drive the blocking member 131 to move from the first position to the second position by the reset assembly, to complete the reset action of the blocking member 131, but also utilize the reverse motion of the driving assembly. That is, the driving mechanism not only drives the blocking member 131 to move to the first position when the anesthetic vaporizer 20 is assembled, but also exposes the insertion hole 111 to the interface 12 for connection of the anesthetic vaporizer 20; moreover, during unloading of the anesthetic vaporizer 20, the drive mechanism may also be moved in an opposite direction, thereby returning the blocking member 131 from the first position to the second position, i.e., shielding the mouthpiece 12, i.e., isolating the mouthpiece 12 from the outside, thereby preventing dust or germs from the outside from contaminating the mouthpiece 12 and harming the patient.
The blocking member 131 may be moved between the first position and the second position by means of translation such as up-and-down movement or left-and-right movement; the shutter 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 such that, when the blocking member 131 is in the first position, the blocking member 131 has a through hole 131 opposite the receptacle 111, i.e., when the blocking member 131 is in the first position, the blocking member 131 does not block the receptacle 111, such that the mouthpiece 12 may be exposed through the receptacle 111 for connection to a corresponding connector on the anesthetic vaporizer 20. When the blocking member 131 rotates relative to the housing 11 to be in the second position, the through hole 131 on the blocking member 131 is staggered from the insertion hole 111, so that the insertion hole 111 is shielded, and the blocking member 131 is blocked between the interface 12 and the insertion hole 111 when the interface 12 is not connected with the anesthetic vaporizer 20, so that external dust or germs are prevented from being contaminated on the interface 12. Of course, in this embodiment, the blocking member 131 may also be moved in a translational manner relative to the housing 11, so as to selectively oppose or misalign the insertion hole 111 with the through hole 131.
It should be noted that, in some specific applications, the number and positions of the through holes 131 may be determined according to the number and positions of the jacks 111, taking the structure shown in fig. 2 and 3 as an example, when the housing 11 is provided with the first jack 111a, the second jack 111b, the third jack 111c and the fourth jack 111d, and when the blocking member 131 is moved to the first position, only the top end of the blocking member 131 is required to be lower than the first jack 111a, and only the first through hole 131a, the second through hole 131b and the third through hole 131c opposite to the second jack 111b, the third jack 111c and the fourth jack 111d are required to be provided on the blocking member 131, respectively, and when the blocking member 131 is moved to the second position, the blocking member 131 is blocked at the interface 12 due to the mutual staggering of the through holes 131 and the interface 12, so as to realize the protection of the interface 12.
In other embodiments, slots or the like are formed in the blocking member 131 to selectively communicate between the receptacle 111 and the port 12. In addition, the blocking member 131 may be formed of a plurality of plates disposed at intervals so that the plurality of plates disposed at intervals open or block the insertion hole 111 when moving between the first position and the second position; specifically, in the first position, the spacing 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 material, thereby preventing the mouthpiece 12 from being exposed from the insertion hole 111 when the anesthetic vaporizer 20 is not assembled to the anesthetic vaporizer connecting seat 10, and preventing external dust or germs from contaminating the mouthpiece 12.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
