In the triggering sensing mechanism of the embodiment of the utility model, the first shell 101 of the triggering component 10 is integrated with the first triggering piece 102 and the second triggering piece 103, and the mounting frame 201 of the sensing component 20 is integrated with the first sensor 202 and the second sensor 203 corresponding to the first triggering piece 102 and the second triggering piece 103, so that components can be unified, the structure is relatively simple, the processing and the production are relatively simple, the unified assembly and the control of the manufacturing cost are convenient, and the accurate detection of at least two detected mechanisms such as a loop module, a soda lime absorption tank or a manual control switching valve can be realized, thereby ensuring the performance of the anesthesia machine.

Referring to fig. 2 to 4, in the present embodiment, the trigger sensing mechanism is mounted on a body of the anesthesia machine, the body of the anesthesia machine includes a lower loop casing 30, a soda lime tank, a manual control switching module, a loop module, and an adapter 40, and the loop module is mounted on the lower loop casing 30 and then connected with the adapter 40 to form a complete breathing loop.

The trigger assembly is disposed on the circuit lower case 30, and specifically, the first case 101 is disposed on the circuit lower case 30, and the first trigger 102 and the second trigger 103 are disposed within the first case 101. The first trigger 102 and the second trigger 103 are configured such that the orientation of the end in contact with the first sensor 202 and the second sensor 203 coincides with the orientation of the connection end of the circuit lower case 30 and the adapter 40, and the second trigger 103 is movable in this direction.

The sensing assembly 20 is disposed on the adaptor 40, the first sensor 202 and the second sensor 203 are fixed on the adaptor 40 by the mounting frame 201, the first sensor 202 corresponds to the first trigger 102, and the second sensor 203 corresponds to the second trigger 103. The first sensor 202 and the second sensor 203 are electrically connected with the controller, and convert the sensed condition into an electric signal and transmit the electric signal to the controller, so that corresponding identification is realized.

Specifically, when the adapter 40 is connected to the circuit lower case 30, the first trigger 102 contacts the first sensor 202, the first sensor 202 forms an electrical signal A1 and transmits the electrical signal A1 to the controller, and the controller determines that the circuit module is in place according to the received electrical signal A1; when the adapter 40 is separated from the circuit lower shell 30, the first trigger 102 is separated from contact with the first sensor 202, the first sensor 202 forms a controller for transmitting the electric signal A2, and the controller determines that the circuit module is removed according to the received electric signal A2.

The mounting position of the first detected mechanism corresponds to the position of the second trigger 103, and the first detected mechanism can push the second trigger 103 to move toward the second sensor 203.

Specifically, the first detected mechanism may be a manual control switching valve. When the manual control switching valve is used for switching between two states of manual control and mechanical control, the valve core states of the manual control switching valve are different, and when the manual state is selected, the valve core is retracted; when the selector is in the controlled state, the valve core stretches out.

When manual operation is selected, the manual operation control switching valve is switched to a manual state, the valve core is retracted, at the moment, the valve core cannot push the second trigger piece 103 to move towards the second sensor 203, the second trigger piece 103 is not contacted with the second controller, the second sensor 203 forms an electric signal B2 to be transmitted to the controller, and the control is carried out according to the received electric signal B2 to judge that the valve core is in the manual state at the moment;

Specifically, the first detected mechanism may be a soda lime tank, and the second detected mechanism may be a manual valve-controlling switching valve.

When the soda lime tank is correctly installed at the preset position, the soda lime tank pushes the second trigger piece 103 to move towards the second sensor 203, so that the second trigger piece 103 is in contact with the second sensor 203, an electric signal B1 is formed by the second sensor 203 and is transmitted to the controller, and the controller judges that the soda lime tank is in an installation state according to the received electric signal B1;

when the soda lime tank is removed or is not correctly installed at the preset position, the soda lime tank cannot push the second trigger piece 103 to move towards the second sensor 203, the second trigger piece 103 is not contacted with the second controller, the second sensor 203 forms an electric signal B2 to be transmitted to the controller, and the soda lime tank is controlled to be in a removal state according to the received electric signal B2.

when the automatic control is selected, the manual control switching valve is switched to a mechanical control state, the valve core stretches out, at the moment, the valve core pushes the third trigger piece 104 to move towards the third sensor 204, so that the third trigger piece 104 is in contact with the third sensor 204, an electric signal C1 is formed by the third sensor 204 and is transmitted to the controller, and the controller judges that the valve is in the mechanical control state at the moment according to the received electric signal C1.

Specifically, the first triggering element 102, the second triggering element 103 and the third triggering element 104 are arranged side by side, and the arrangement structure is compact, ordered in arrangement and space-saving.

In this embodiment, the mounting seat 205 includes a mounting portion, a guide rod, and a third elastic member 206. The mounting portion is used to mount the first sensor 202, the second sensor 203, or the third sensor 204. The guide rod is arranged on the mounting part, the adapter 40 is provided with a guide groove matched with the guide rod, and the guide rod drives the mounting part to slide in the guide groove. The guide rod is sleeved with a third elastic element 206, and the third elastic element 206 is abutted with the outer wall of the machine body.

In particular, the third resilient element 206 may be a spring. When the external force F3 is not received by the mounting portion, the spring is original. When the mounting portion is subjected to an external force F3 and moves towards the adapter 40, the spring is compressed, the mounting portion is subjected to an elastic force T3 of the spring, and the mounting portion is far away from the adapter 40 due to the elastic force T3 of the spring, and at this time, F3 > T3. When the external force applied to the mounting portion is removed, the mounting portion moves away from the adapter 40 under the action of the elastic force T3 until the spring returns to its original length.

On the basis of the fourth embodiment, the first movable rod 105 includes a third transmission portion movably connected to the first detected mechanism, a third contact portion connected to the third transmission portion, and a third limit portion disposed between the third transmission portion and the third contact portion, where the third contact portion is movably connected to the first transmission portion.

In this embodiment, one end of the first rod, which is movably connected to the first detected mechanism, is a third transmission portion, one end of the first rod, which is connected to the third transmission portion, is a third contact portion, and a third limiting portion for limiting is disposed in the middle of the rod.

Specifically, the setting direction of the first movable lever 105 is perpendicular to the setting direction of the second trigger 103, and the first movable lever 105 is vertically set. The contact surface between the third contact portion and the first transmission portion of the second trigger member 103 is a smooth curved surface.

The first detected mechanism contacts with the third transmission part to push the first movable rod 105 to move vertically downwards, and the second trigger piece 103 is driven to move horizontally towards the second sensor 203 through the smooth contact surface of the third contact part and the first transmission part, so that the first contact part of the second trigger piece 103 contacts with the second sensor 203.

Example eleven

On the basis of the tenth embodiment, the trigger assembly 10 further includes:

the second housing 110 is arranged on the top of the first housing 101, and the first movable rod 105 can move in the second housing 110 along the height direction of the second housing 110;

the second limiting piece 111 is arranged on the bottom surface of the second shell 110, and the third contact part passes through the second limiting piece 111 and is movably connected with the first transmission part; and

the fourth elastic element 112 is sleeved on the third contact portion, and the fourth elastic element 112 is located between the third limiting portion and the second limiting member 111.

In this embodiment, the second housing 110 is disposed on top of the first housing 101, and a channel capable of accommodating the first movable rod 105 moving in the vertical direction is disposed on the second housing 110, and a channel adapted to the channel on the second housing 110 is disposed on the first housing 101, so that the first movable rod 105 can penetrate the second housing 110 to contact with the second trigger 103 disposed on the first housing 101.

The bottom of the second housing 110 is provided with a second limiting part 111, a through hole capable of allowing the third contact part to pass through is formed in the second limiting part 111, and the size of the through hole cannot allow the third limiting part to pass through. A counter bore is formed in the bottom of the second housing 110, the aperture of the counter bore is matched with the third contact portion, and the size of the counter bore is matched with the third limit portion. The third contact portion is sleeved with a fourth elastic element 112, and the fourth elastic element 112 is located between the third limiting portion and the second limiting piece 111.

Specifically, the fourth elastic member 112 may be a spring that is original in length when the first movable lever 105 is not pushed downward by the first detected mechanism. The first movable rod 105 can move within the depth range of the counter bore on the second housing 110, so that other elements are prevented from being damaged due to the excessive moving distance.

When the first movable rod 105 moves toward the first housing 101 under the thrust force F4 exerted by the first detected mechanism, the spring is compressed, the first movable rod 105 is under the elastic force T4 of the spring, T4, so that the first movable rod 105 is far away from the first housing 101, and at this time, F4 > T4. When the pushing force F4 exerted by the first detected mechanism and received by the first movable rod 105 is removed, the first movable rod 105 moves away from the first housing 101 under the action of the elastic force T4 until the spring returns to its original length.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
