A foam ball 62 is installed at the center of the detection cavity 63 by an elastic rope 61. The foam ball 62 can achieve a certain range of displacement through the elastic rope 61, and the elastic rope 61 is in a relaxed state. At the same time, an infrared displacement detector 11 is provided on one side of the exhalation valve 6, and the infrared displacement detector 11 is used to dynamically monitor the foam ball 62 provided inside the exhalation valve 6, wherein the infrared displacement detector 11 is electrically connected to the single-chip microcomputer control component 17 provided in the equipment cabin 9 through a wire 24.

[0027] Reference Figure 5-9 A control cabin 91 is provided on one side of the equipment cabin 9, and a single-chip control component 17 is installed in the control cabin 91. The control end of the single-chip control component 17 is electrically connected to a micro motor 19. The micro motor 19 is fixedly installed on one side of the interior of the equipment cabin 9, and the output shaft end of the micro motor 19 is drivingly connected to an eccentric disk 21. A connecting rope 18 is installed in the middle of the other side of the eccentric disk 21. The other end of the connecting rope 18 is connected to a safety ring 8, wherein the safety ring 8 is limitedly clamped at one end of the equipment cabin 9, and the safety ring 8 can be forcibly pulled out by external force intervention.

[0028] Among them, the single-chip microcomputer control component 17 includes a control end composed of a single-chip microcomputer component and a PCB board component, thereby ensuring the normal operation of the micro motor 19 and the infrared displacement detector 11. Its specific operating principle is already an existing technology, so it will not be elaborated on.

[0029] Furthermore, a movable groove 22 is provided on one side of the inner bottom end of the equipment cabin 9, that is, on the lower side of the bottom of the eccentric disk 21, and a push rod 221 is installed in the movable groove 22 for limiting movement. The push rod 221 can achieve a certain degree of lifting and lowering displacement in the movable groove 22. At the same time, limit blocks 222 are provided on both sides of the push rod 221. The limit blocks 222 slide in the movable groove 22 to ensure the mobility of the push rod 221. At the same time, a spring 223 is provided at the bottom of the limit block 222, and the other end of the spring 223 is connected to the bottom wall of the movable groove 22. When the push rod 221 drives the limit block 222 to move, the spring 223 is deformed.

[0030] Among them, the top end of the push rod 221 extends out of the top of the movable groove 22 and is squeezed and contacted with the bottom wall of the eccentric disk 21, and the bottom end of the push rod 221 extends out of the bottom of the movable groove 22 and extends into the interior of the air intake pipe 7.

[0031] Reference Figure 7 The output shaft end of the micro motor 19 is clamped into the tie groove 211 opened inside the eccentric disk 21, and because the tie groove 211 has an inner tie structure, the output shaft end of the micro motor 19 is stably clamped into the tie groove 211 to meet the power output, and under the action of external force, the eccentric disk 21 is separated from the output shaft end of the micro motor 19.

[0032] Among them, a disk body is eccentrically arranged in the middle of the eccentric disk 21, and the bottom of the disk body is in compression contact with the top of the push rod 221. During the rotation of the eccentric disk 21, the contact surface position of the disk body and the push rod 221 is displaced due to the eccentric setting, thereby causing the push rod 221 to rise.

[0033] Reference Fig. 9 A button battery 25 is provided on one side of the single-chip control component 17, and the button battery 25 ensures its normal operation.

[0034] Furthermore, a control end of the single-chip control component 17 is connected to a wire 24 , and the other end of the wire 24 is electrically connected to the infrared displacement detector 11 .

[0035] Reference Figure 10-11 A reset steel bar 161 is vertically penetrated and fixedly installed in the middle of the opening and closing plate 16. The ends of the reset steel bar 161 are bent and limitedly installed on the top and bottom walls of the inner wall of the air intake pipe 7. In the natural state, the reset steel bar 161 twists to one side and generates a torsional force. At this time, the opening and closing plate 16 is closed and the air intake pipe 7 is closed and sealed.

[0036] Among them, a sealing ring 162 is provided on the outer side of the opening and closing plate 16, and the sealing ring 162 is limitedly clamped and installed in the annular groove 23 opened on the inner wall of the intake pipe 7, thereby ensuring the closing stability of the opening and closing plate 16 in the natural state.

[0037] In this embodiment, the mask body 1 is aligned with the patient's head and covers the patient's face, and the mask body 1 is fixed to the patient's head by the strap 4 to ensure the stability of the mask when in use, and then the external drug supply device is connected to the drug supply tube 5 provided in the middle of the mask body 1, and the high-concentration oxygen gas is filled into the airbag 71.

[0038] Among them, the mask body 1 ensures the stability of covering the patient's face through the rubber pressure pad 2, and ensures the airtightness of the internal cavity of the mask body 1. When the anesthetic mixed gas is input into the mask body 1 through the drug supply tube 5, the patient inhales the anesthetic gas and the corresponding waste gas is discharged by the exhalation valve 6. Among them, since the mask body 1 is provided with a guide cover 10, the guide cover 10 is arranged at the mouth and nose position of the patient, which can effectively guide the waste gas discharged by the patient and introduce the waste gas into the exhalation valve 6 arranged on the outside of the mask body 1 through the guide cover 10.

[0039] Furthermore, during the medication process, when the patient experiences emergency situations such as respiratory depression or suffocation, he or she cannot actively inhale the anesthetic mixed gas, resulting in the accumulation of waste gas discharged by the patient and the input anesthetic gas inside the hood body 1. At this time, the gas flow rate of the airflow at the guide hood 10 is lower than that of the normal exhalation condition. At this time, the foam ball 62 set in the exhalation valve 6 is less affected by the airflow, and its movement amplitude tends to decrease and stop. At this time, the infrared displacement detector 11 set on one side of the exhalation valve 6 detects that the corresponding displacement of the foam ball 62 is reduced, and transmits the corresponding electrical signal to the single-chip control component 17 set in the equipment cabin 9 through the wire 24. The single-chip control component 17 excites and controls the micro motor 19 connected thereto, and the micro motor 19 is The eccentric disk 21 is stimulated and driven to rotate. The eccentric disk 21 rotates and causes the top rod 221 connected to the bottom to rise. At this time, the bottom of the top rod 221 loses the interaction force with the opening and closing plate 16 set in the air inlet pipe 7. The reset steel bars 161 set at both ends of the opening and closing plate 16 are stress-released to drive the reset steel bars 161 to rotate axially and be parallel to the fluid flow direction of the air inlet pipe 7, that is, the opening and closing plate 16 is opened and the gas in the air inlet pipe 7 is allowed to circulate. Due to the setting of the airbag 71, the high-concentration oxygen gas filled in the airbag 71 enters the interior of the cover body 1 through the air inlet seat 20 after the opening and closing plate 16 is opened, and under the action of the gas push, the excitation plate 12 tilts and tilts up, and blocks the air inlet seat 13 below, thereby limiting the entry of anesthetic gas.

[0040] At this time, a large amount of oxygen is input into the mask body 1, and the patient is provided with the oxygen required to assist his or her spontaneous breathing. At this time, the operator takes out the airbag 71 connected to the air inlet pipe 7 from the jacket 15, and at the same time, the originally inflated airbag 71 shrinks sharply and reminds the operator.

[0041] Furthermore, the operator can still pull out the safety ring 8 provided on one side of the equipment cabin 9 with force, so that the safety ring 8 drives the eccentric disk 21 to move outward through the internally connected connecting rope 18, and the eccentric disk 21 is separated from the output shaft end of the micro motor 19, and the top rod 221 provided at the bottom loses the interaction force and is quickly lifted by the spring 223, so that the opening and closing plate 16 rotates open.

[0042] Among them, in actual application, in the normal drug supply process, the anesthetic mixed gas introduced into the drug supply tube 5 will enter the interior of the mask body 1 through the air inlet seat 13. At this time, the anesthetic gas will produce a certain thrust on the excitation plate 12 at the air inlet seat 13, thereby causing one end of the excitation plate 12 to tilt up, and the other end is stably covered on the upper air inlet seat 20, that is, the air inlet pipe 7. Conversely, in the oxygen supply stage, the air inlet seat 20 is opened and the air inlet seat 13 is closed. This is easy to understand intuitively and will not be elaborated here.

[0043] Among them, in actual application, the reset steel bars 161 arranged at both ends of the opening and closing plate 16 twist in a natural state and generate a certain torsional force. Before the opening and closing plate 16 is opened, the torsional force generated by it is limited by the push rod 221; and after the opening and closing plate 16 is opened, the energy stored in the reset steel bar 161 is released, and drives the opening and closing plate 16 to rotate rapidly, and the air intake pipe 7 is opened.

[0044] Among them, since the air intake pipe 7 is filled with high-concentration oxygen gas by the air bag 71, the stored gas has a certain air pressure.

[0045] Among them, in actual application, the connection between the ball seat 14 and the ball head 121 allows the ball head 121 to be fine-tuned in any direction, so that the excitation plate 12 can be deflected at a certain angle, and the sealing gasket 122 arranged on the inner wall of the excitation plate 12 can effectively block and close the air inlet seat 20 and the air inlet seat 1 13 accordingly.

[0046] Among them, in actual application, the two ends of the foam ball 62 are constrained by elastic ropes 61. When the gas passes through the detection chamber 63 set inside the exhalation valve 6, the airflow causes the foam ball 62 to swing irregularly. When the airflow decreases, the movement amplitude of the foam ball 62 decreases or stops. At this time, the infrared displacement detector 11 recognizes its corresponding movement state. The movement amplitude of the foam ball 62 does not meet the set threshold of the infrared displacement detector 11 and stimulates the infrared displacement detector 11. The infrared displacement detector 11 transmits the corresponding electrical signal to the single-chip control component 17 through the wire 24.

[0047] Among them, in actual application, a disk body is eccentrically arranged in the middle part of the eccentric disk 21, and the bottom of the disk body is in compression contact with the top of the push rod 221. During the rotation of the eccentric disk 21, the contact surface between the disk body and the push rod 221 is displaced due to the eccentric arrangement, and the push rod 221 in contact with it is returned to the top and rises through the spring 223.

[0048] Among them, in actual application, the installation position of the push rod 221 does not correspond to the middle of the opening and closing plate 16. The installation position of the push rod 221 is in the middle of the opening and closing plate 16, biased towards the control cabin 91, that is, biased towards the rotation direction of the opening and closing plate 16, thereby effectively limiting the opening and closing plate 16.

[0049] Among them, it is worth noting that the infrared displacement detector 11 uses an infrared sensor to detect the infrared radiation emitted by an object. When the foam ball 62 moves, its infrared radiation will change, thereby completing the corresponding excitation instruction. Its specific principle and internal components are already existing technologies and will not be elaborated here.

[0050] Among them, it is worth noting that the single-chip microcomputer control component 17, that is, comprises a single-chip microcomputer component and a PCB board component, wherein the PCB board component is used to carry the single-chip microcomputer component, and under the connection of the control harness and the wire 24, the infrared displacement detector 11 and the micro motor 19 are excited and controlled, which is realized through the corresponding control instructions. Its detailed control principle and connection relationship are already the prior art and are common knowledge of technicians in this field, so they will not be elaborated here.

[0051] Among them, it is worth noting that the reset steel bar 161, its principle is through the elasticity of the steel bar, it stores a certain amount of energy after deflection and bending, and performs rapid rotation and reset after excitation, and realizes the operation of the corresponding components. Its principle is the same as the spacer metal bar used in the mechanical keyboard, which is easy to understand and will not be elaborated here.

[0052] In the present invention, a foam ball 62 is arranged in the exhalation valve 6 of the mask body 1, and the foam ball 62 moves and displaces with the patient's breathing. When an emergency such as respiratory depression occurs, the airflow at the foam ball 62 is reduced, so that the movement amplitude of the foam ball 62 stops or decreases. At this time, the infrared displacement detector 11 recognizes the corresponding movement state of the foam ball 62, and stimulates the opening and closing plate 16 in the air inlet pipe 7 to open to introduce high-concentration oxygen to ensure the patient's oxygen inhalation needs. It can effectively and timely respond to adverse conditions such as respiratory depression and suffocation. The process is convenient to operate and responds quickly, effectively ensuring stability and safety during use.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
