The first temperature sensor 104 and the flow sensor 102 are electrically connected. The rotating drum 103 is slidingly connected with four symmetrically distributed heating tubes 105. The heating tubes 105 are electrically connected to the first temperature sensor 104. The middle part of the instrument pipe section 1 is rotatably connected to a toothed disc 106. The symmetrically distributed heating tubes 105 all slide with the toothed disc 106. connection, the rotation of the toothed disc 106 drives the heating tube 105 and the drum 103 to rotate together. The symmetrically distributed heating tubes 105 are connected with the toothed disc 106 by a first spring 107.

The output shaft of the small motor 108 is connected to a gear 109. The gear 109 meshes with the gear plate 106. A microcontroller 110 is provided on the right side of the flow sensor 102. The microcontroller 110 and the flow sensor 102 are electrically connected. connection, there is a signal receiver 111 slidingly connected to the right side of the instrument pipe section 1. The signal receiver 111 is annular. The signal receiver 111 is electrically connected to the microcontroller 110. There are two electric pushers on the right side of the signal receiver 111. Rod 112, the electric push rod 112 and the signal receiver 111 are electrically connected. A push frame 113 is connected between the telescopic rods of the two electric push rods 112. The push frame 113 is slidingly connected to the instrument pipe section 1, and the push frame 113 is close to the toothed plate. One side of 106 is a hollow circular cone. The diameter of the left side of the hollow circular cone is smaller than the diameter of the right side. The left side of the hollow circular cone is in contact with the heating pipe 105. The hollow circular cone contacts and cooperates with the heating pipe 105. The hollow circular cone of the push frame 113 is fixedly connected with an arc rod. A hollow circular cone is also provided on the left side of the rod. A V-shaped rod is connected to the left end of the heating tube 105. The larger diameter side of the hollow circular cone connected to the arc rod is inserted into the v-shaped rod. The push frame 113 moves to the left so that the two hollow circular cones are evenly spaced. Moving to the left, the heating tube 105 and the V-shaped rod are squeezed by the adjacent hollow circular cone and move outward. Through the arrangement of the two hollow circular cones, the heating tube can maintain balance when moving outward. The first temperature sensor 104, the heating tube 105, the small motor 108, and the microcontroller 110 are electrically connected to the control module respectively, and receive or send instructions to them through the control module.

When an anesthesia machine needs to be used for anesthesia, the operator first energizes the entire device, and the evaporated anesthetic in the anesthesia machine flows out of the instrument pipe section 1 through the rotation of the turbine 101. At the same time, the operator adjusts the flow rate of the anesthetic according to the actual situation, and passes through the flow sensor 102 Monitor the anesthetic flow in instrument pipe section 1. Due to the low external temperature, the anesthetic gas in instrument pipe section 1 will shrink, resulting in the gas flow output from instrument pipe section 1 being smaller than the preset value and the gas concentration being larger than the preset value. , at this time, the gas in the instrument pipe section 1 is heated, so that the final gas flow rate and concentration output from the instrument pipe section 1 are consistent with the preset values, which are divided into the following two situations:

When the preset anesthetic flow rate is relatively large, the anesthetic flow rate input into the instrument pipe section 1 is relatively large. Due to the external low temperature environment, the anesthetic gas in the instrument pipe section 1 shrinks, causing the gas flow rate output from the instrument pipe section 1 to be larger than the preset flow rate. The flow rate is small, the gas concentration output from the instrument pipe section 1 is greater than the preset concentration, and the first temperature sensor 104 detects that the surrounding temperature is low, and the heating tube 105 is controlled by the control module to heat, and the flow sensor 102 detects When the flow is flowing, the control module controls the start of the small motor 108. The output shaft of the small motor 108 rotates to drive the gear 109 to rotate, causing the gear plate 106 to rotate, thereby driving the heating tube 105 and the drum 103 to rotate together, so that the heating tube 105 is opposite to the instrument pipe section. 1. Heating evenly, the temperature of the instrument pipe section 1 increases through heating, causing the gas in the instrument pipe section 1 to expand, increasing the anesthetic flow rate, and further diluting the anesthetic concentration to reach the standard state;

When the preset anesthetic flow rate is relatively small, the anesthetic flow rate input into the instrument pipe section 1 is small. If the heating tube 105 is heated close to the instrument pipe section 1, the gas temperature in the instrument pipe section 1 will be too high, resulting in excessive expansion of the anesthetic gas, further As a result, the gas flow rate is too large and the concentration is too thin, resulting in the output gas flow rate being higher than the preset value. To avoid this situation, when the flow sensor 102 detects that the anesthetic flow rate in the instrument pipe section 1 is low, the flow sensor 102 will Send an electrical signal to the microcontroller 110, and the microcontroller 110 sends a signal to the signal receiver 111, so that the signal receiver 111 receives the signal and controls the telescopic end of the electric push rod 112 to shorten through the control module, thereby driving the push frame 113 to move to the left. , so that the push frame 113 squeezes the heating tube 105 and moves outward, the first spring 107 is compressed, and the heating tube 105 moves outward away from the instrument pipe section 1, thereby weakening the heating of the anesthetic in the instrument pipe section 1, so that the anesthetic in the instrument pipe section 1 is heated. The heat is weakened, thereby ensuring that the gas flow rate and concentration output from the instrument pipe section 1 are consistent with the preset values.

When the anesthetic transfer is completed, the flow sensor 102 does not detect the flow and transmits a signal to the first temperature sensor 104 through the control module. The control module then controls the heating tube 105 to close, controls the small motor 108 to close at the same time, and sends a signal to the microcontroller 110 , causing the microcontroller 110 to control the telescopic end of the electric push rod 112 to extend, causing the push frame 113 to move to the right, so that the push frame 113 no longer squeezes the heating tube 105, and the first spring 107 resets to drive the heating tube 105 to reset.

In summary, this device controls the heating tube 105 to heat the instrument pipe section 1 through the flow sensor 102, thereby regulating the flow and concentration of the anesthetic in the instrument pipe section 1, thereby ensuring the flow and concentration of the anesthetic in a low-temperature environment and preventing the anesthetic from being affected by temperature. The output flow and concentration are inconsistent with the set flow and concentration, which affects the anesthesia effect on the patient during surgery.

Example 2:

On the basis of Embodiment 1, with reference to Figures 3 to 5, the flow sensing and measuring device in the anesthesia machine in this embodiment also includes a heat dissipation component for regulating when the temperature is too high. The heat dissipation component is configured Between the toothed disc 106 and the rotating drum 103, the temperature dissipation assembly includes a temperature control cylinder 2.

The second temperature sensor 202 is electrically connected to the first electromagnet 203. The sensor 202 and the first electromagnet 203 are electrically connected to the control module respectively.

When the instrument pipe section 1 is heated to a temperature that is too high, it may result in a larger flow rate and a thinner concentration. Therefore, timely heat dissipation is required to allow the anesthetic in the instrument pipe section 1 to return to the normal state. If the second temperature sensor 202 detects that the temperature is too high, it will The control module controls the first electromagnet 203 to be energized, so that the first electromagnet 203 attracts the first magnet 204, thereby driving the baffle 201 to move inward, the second spring 206 is compressed, and the baffle 201 moves inward and no longer blocks the control panel. The temperature cylinder 2 allows the heat in the instrument pipe section 1 and the heat in the temperature control cylinder 2 to dissipate, thereby cooling the instrument pipe section 1 so that the anesthetic flow rate in the instrument pipe section 1 can gradually decrease as the temperature decreases to reach a normal value.

Referring to Figure 6, the flow sensing and measuring device in the anesthesia machine in this embodiment also includes a preheating component for preheating the instrument pipe section 1.

The third temperature sensor 3 and the second electromagnet 302 are electrically connected to the control module respectively.

When the entire device is powered on, indicating that the operator is about to use the device, if the third temperature sensor 3 detects a low temperature at this time, the control module will control the heating tube 105 to be powered on. At this time, the heating tube 105 is close to the instrument pipe section 1. As a result, the instrument pipe section 1 can be quickly heated, and the impact of low temperature on the anesthetic flow in the instrument pipe section 1 under initial conditions can be quickly reduced through preheating; when the flow sensor 102 detects that the anesthetic flows through the instrument pipe section 1, the control module controls the heating pipe 105 Close, and control the second electromagnet 302 to be energized, so that the second electromagnet 302 attracts the second magnet 303, thereby driving the signal receiver 111 and the electric push rod 112 to move to the left, causing the push frame 113 to move to the left, and then driving the heating tube 105 moves outward, and the first spring 107 is compressed, so that the heating tube 105 is at a certain distance from the instrument pipe section 1 after preheating, to prevent the heating tube 105 from being close to the instrument pipe section 1 during the subsequent heating process. Too much traffic.

Example 3:

In this way, when the temperature control cylinder 2 follows the rotation of the gear plate 106 and the rotating cylinder 103, the wind is introduced into the temperature control cylinder 2 through the inclined guide plate 401, speeding up the control. The cooling inside the temperature cylinder 2 and the instrument pipe section 1 achieves the purpose of timely heat dissipation.

When the anesthetic flow rate is small, the heating tube 105 is still heating the instrument pipe section 1, and there is a certain amount of heat in the temperature control cylinder 2, but the temperature has not reached the set value of the second temperature sensor 202 at this time, so This part of the heat needs to be dissipated. When the anesthetic flow is small, according to the above working principle, the heating tube 105 will move outward. When the heating tube 105 moves outward, it will come into contact with the lever 501, thereby squeezing the lever 501. , so that the lever 501 is tilted, and the side connected to the second fixed block 5 of the lever 501 moves inward, thereby driving the second fixed block 5 to move inward, so that the first magnet 204 drives the baffle 201 to move inward, so that There is a gap between the baffle 201 and the temperature control cylinder 2 to dissipate heat and ensure the temperature balance in the temperature control cylinder 2 .
