Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent auxiliary device for clinical anesthesia intubation used in anesthesiology departments. Background Art

[0002] The clinical anesthesia intubation intelligent auxiliary device for anesthesiology is an intelligent auxiliary device specially designed for tracheal intubation operations during clinical anesthesia. It aims to improve the accuracy, safety and efficiency of tracheal intubation operations.

[0003] Existing technologies such as the AutoSecure intelligent endotracheal tube fixation device have a one-button automatic fixation and release function for the tube. Since traditional manual fixation requires the steps of sticking tape, wrapping inch tape and adjusting the tightness, it takes a long time and relies on the doctor's experience. AutoSecure uses a one-button trigger mechanism to simultaneously complete the positioning and locking of the tube, compressing the fixation time to within a few seconds, so it can significantly improve the efficiency of intubation. And when the tube needs to be removed at the end of the operation, it can also quickly release the tube with a one-button operation. At this time, because the intubation method is mechanical intubation, the intubation depth is relatively fixed and the stability is higher than manual intubation, so it can reduce irritation to the patient's airway.

[0004] However, the fixing method adopted by the above-mentioned device during intubation is a single fixing method for the cannula, and it does not fix the patient's head. The patient may unconsciously deviate his head after anesthesia, making it difficult to keep the cannula stably inserted in the patient's mouth. Therefore, if the patient's head is not fixed, the patient's head may deviate and cause the cannula to fall off, thereby causing secondary injury to the patient.

[0005] To sum up, the existing device does not fix the patient's head, and the patient's head may shift, causing the cannula to fall off, causing secondary injury to the patient. This has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose an intelligent auxiliary device for clinical anesthesia intubation for anesthesiology. Summary of the Invention

[0006] To solve the above problems, the present invention provides an intelligent auxiliary device for clinical anesthesia intubation for use in the anesthesiology department. By fixing the patient's head through a head fixing component, the device can effectively reduce the impact of the patient's head shaking on the intubation, thereby keeping the intubation in the correct airway position at all times, and reducing the risk of intubation displacement due to patient head movement, which may cause irritation to the patient.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an intelligent auxiliary device for clinical anesthesia intubation for anesthesiology, comprising a cannula, a controller and a shell, a plurality of annular grooves being equidistantly provided on the outer wall of the cannula, a support block being symmetrically fixedly connected to the bottom of the shell, a support frame being fixedly connected to the inner wall of the shell, a telescopic part being fixedly connected to the support frame, and a controller being used to control the extension and retraction of the output shaft of the telescopic part.

[0008] The support frame is provided with a first cannula fixing component for preliminarily fixing the cannula in the patient's mouth, and a second cannula fixing component is provided on one side of the shell for secondary fixing the cannula in the patient's mouth. The support frame is also provided with a driving component for driving the first cannula fixing component and the second cannula fixing component to operate.

[0009] A head fixing assembly for fixing the patient's head is provided on one side of the shell, and the head fixing assembly is located below the second cannula fixing assembly. The shell is also provided with an auxiliary fixing assembly for assisting the head fixing assembly to fix the patient's head and perform protective operations on the patient's head.

[0010] The technical principles of the above solution are as follows:

[0011] The medical staff places the cannula in the patient's mouth so that the cannula is located in the movement path of the first cannula fixing component and the second cannula fixing component. Then, the controller controls the output shaft of the telescopic component to retract, so that it drives the driving component to operate, and the driving component drives the first cannula fixing component and the second cannula fixing component to perform multiple fixing operations on the cannula in the patient's mouth.

[0012] During operation, the second intubation fixing component will also drive the operation of the head fixing component and the auxiliary fixing component. The head fixing component will be used to fix the patient's head, and the auxiliary fixing component will be used to enhance the fixing effect of the head fixing component on the patient's head and protect the patient's head.

[0013] The above scheme has the following beneficial effects:

[0014] 1. The present invention fixes the patient's head through a head fixing assembly, which can effectively reduce the impact of the patient's head shaking on the intubation tube, so that the intubation tube always remains in the correct airway position, reducing the risk of intubation displacement caused by patient head movement and causing irritation to the patient.

[0015] 2. The present invention uses a first cannula fixing component to initially fix the cannula in the patient's mouth, and uses a second cannula fixing component to perform secondary fixation on the cannula, forming a multi-point fixation mode, which greatly improves the stability of the cannula in the patient's mouth.

[0016] 3. The present invention integrates the functions of intubation fixation, head fixation and auxiliary fixation and uniformly controls them through a controller, so that medical staff do not need to use multiple independent devices separately when performing anesthesia intubation operations, which simplifies the operation process and improves the convenience of operation.

[0017] Furthermore, the driving assembly includes a double-sided rack fixedly connected to the output shaft of the telescopic member, and a fan-shaped tooth block is symmetrically rotated on the support frame, and the fan-shaped tooth block is engaged with the double-sided rack; the double-sided rack is fixedly connected to an extension rod at one end away from the output shaft of the telescopic member, and the extension rod is fixedly connected to a measuring frame at one end away from the double-sided rack, and a measuring wheel is rotated inside the measuring frame; a liquid storage tank is fixedly connected to the top of the outer shell, a liquid inlet is opened at the top of the liquid storage tank, and a rubber plug is detachably connected to the liquid inlet, a liquid outlet pipe is connected to one side of the liquid storage tank, and a nozzle is connected to the end of the liquid outlet pipe away from the liquid storage tank, the nozzle is fixedly connected to the top of the measuring frame, and the measuring wheel is located on one side of the nozzle.

[0018] Benefits: The design of a double-sided rack meshing with symmetrically distributed sector-shaped gear blocks ensures that the linear motion of the telescopic output shaft is accurately converted into the rotational motion of the sector-shaped gear blocks. Compared with other transmission methods, the meshing transmission of racks and gears has higher transmission accuracy and can effectively reduce errors during the transmission process.

[0019] Furthermore, the first cannula fixing assembly includes a first piston box fixedly connected to the support frame, the inner wall of the first piston box is slidably fitted with a first piston plate, and the first piston plate is fixedly connected to the output shaft of the telescopic member; the first piston box is connected to a first solenoid valve, and the controller is used to control the opening and closing of the first solenoid valve. The first piston box is connected to a cannula fixing airbag through the first solenoid valve, and the cannula fixing airbag is located outside the shell.

[0020] Beneficial Effect: When the telescopic output shaft moves, the first piston plate slides within the first piston box, generating airflow. This movement, through the first solenoid valve, changes the air pressure within the first piston box, thereby controlling the inflation or deflation of the tube-securing airbag. When inflated, the airbag secures the endotracheal tube tightly, applying uniform pressure from multiple directions to the tube, achieving a stable and precise fixation.

[0021] Furthermore, the second cannula fixing assembly includes a first connecting rod fixedly connected to the fan-shaped tooth block, the first connecting rods extend through the side wall of the shell to the outside of the shell and are hinged with a fixing rod, the second connecting rods are symmetrically hinged on the support frame, the second connecting rods are hinged to the adjacent fixing rods, the fixing rods are fixedly connected to the fixing blocks, a through groove is opened on the side wall of the shell, and the first connecting rod and the second connecting rod are both located in the through groove.

[0022] Beneficial Effects: The fixing block on the fixing rod works in conjunction with the cannula fixing airbag to clamp the cannula, creating a multi-point fixation effect. Compared to single-point fixation, multi-point fixation can better distribute the external force on the cannula, reducing the possibility of cannula displacement or deformation due to uneven force.

[0023] Furthermore, the head fixing assembly includes a fixing plate fixedly connected to the bottom of the fixing rod, and the fixing plate is fixedly connected to the head fixing airbag.

[0024] Beneficial effects: The head fixation airbag can adaptively fit according to the shape and size of the patient's head. It can automatically adjust its shape according to the patient's head shape, fill the gap between the head and the fixation plate, provide uniform and stable fixing force, and thus improve the accuracy of head fixation.

[0025] Furthermore, the auxiliary fixing assembly includes a second piston box symmetrically fixedly connected to the outer wall of the outer shell, the inner walls of the second piston box are slidably fitted with a second piston plate, one side of the second piston plate is fixedly connected to a hinged rod, and the end of the hinged rod away from the second piston plate passes through the side wall of the second piston box and extends to the outside of the second piston box and is hinged to the adjacent fixed rod; the second piston box is connected to a second solenoid valve, and the controller is used to control the opening and closing of the second solenoid valve, and the second piston box is connected to the adjacent head fixing airbag through the second solenoid valve.

[0026] Beneficial Effect: When the second piston plate moves, the air pressure within the second piston box changes, causing the head fixation airbag to expand or contract, providing a more stable fixation force for the patient's head. This, together with the fixation plate, forms a multi-layered fixation system, significantly enhancing the stability of the patient's head fixation. This prevents head shaking during anesthesia, which could affect the intubation position or cause unexpected situations.

[0027] Furthermore, the fixing block is U-shaped, and a buffer layer is fixedly connected to the fixing block.

[0028] Beneficial effects: The U-shaped fixing block design is compatible with the tubular structure of the cannula. Compared with flat or unilateral fixing methods, it can fit the cannula more closely and reduce the shaking space of the cannula in the fixing block, thereby greatly enhancing the fixation effect and ensuring that the cannula maintains a stable position during anesthesia.

[0029] Furthermore, a rubber layer is fixedly connected to both the first piston plate and the second piston plate.

[0030] Beneficial effect: The rubber layer has good sealing performance. When the first piston plate and the second piston plate slide in the first piston box and the second piston box, the rubber layer can fit tightly against the inner side walls of the first piston box and the second piston box, thereby making the first piston plate and the second piston plate more stable during movement.

[0031] Furthermore, the intubation fixing balloon is designed to be ring-shaped.

[0032] Beneficial effects: The annular design of the intubation fixing airbag can wrap and fix the intubation from the entire circumference direction. Compared with other shapes of fixing structures, its annular design can ensure that the intubation is subjected to uniform fixing force in all directions, preventing the intubation from deflecting, rotating or shaking during anesthesia, thereby greatly improving the stability of the intubation.

[0033] Furthermore, an elastic band is fixedly connected to the outer side wall of the intubation fixing airbag.

[0034] Beneficial Effects: The elastic band has a certain degree of elasticity, allowing medical staff to flexibly adjust the tightness of the band according to the patient's specific condition and surgical needs. For patients with delicate oral tissue or those who are sensitive to pressure, the band can be loosened appropriately to reduce pressure on the patient; for patients requiring more stable fixation, the band can be tightened to enhance the fixation effect, making the fixation method more personalized and meeting the needs of different patients.

DETAILED DESCRIPTION

[0041] The following is further described in detail through specific implementation methods:

[0042] Example 1:

[0043] As attached Figure 1 and Figure 2 The device is an intelligent anesthesia intubation assist device for use in anesthesiology departments. The device comprises a cannula (not shown), a controller, and a housing 1. The outer wall of the cannula is provided with a plurality of equally spaced annular grooves. Support blocks 2 are symmetrically welded to the bottom of the housing 1, and a support frame 3 is welded to the inner wall of the housing 1. A telescopic member is bolted to the support frame 3. The controller controls the extension and retraction of the output shaft of the telescopic member. In this embodiment, the telescopic member is an electric telescopic rod.

[0044] A first cannula fixing component is provided on the support frame 3 for preliminarily fixing the cannula in the patient's mouth, and a second cannula fixing component is provided on one side of the shell 1 for secondary fixing the cannula in the patient's mouth. The support frame 3 is also provided with a driving component for driving the first cannula fixing component and the second cannula fixing component to operate.

[0045] like Figure 2 As shown, the drive assembly includes a double-sided rack 4 bolted to the output shaft of the electric telescopic rod. A support frame 3 is symmetrically rotated with a sector-shaped tooth block 5, each of which meshes with the double-sided rack 4. An extension rod is welded to the end of the double-sided rack 4, away from the output shaft of the telescopic member. A measuring frame is welded to the end of the extension rod away from the double-sided rack 4, and a measuring wheel rotates within the measuring frame. A liquid reservoir is welded to the top of the housing 1, with a liquid inlet at the top of the reservoir and a removable rubber stopper at the inlet. A liquid outlet pipe is connected to one side of the reservoir, and the end of the outlet pipe away from the reservoir is connected to a nozzle, which is screwed to the top of the measuring frame. The measuring wheel is located on the side of the nozzle. In this embodiment, the measuring wheel is made of sponge.

[0046] Specifically, because the double-sided rack 4 is bolted to the output shaft of the electric telescopic rod, when the output shaft contracts, it can drive the double-sided rack 4 to move laterally. At this time, because the sector-shaped tooth blocks 5, which are rotatably coupled to the support frame 3, are all engaged with the double-sided rack 4, the double-sided rack 4 can cause the sector-shaped tooth blocks 5 to swing during the lateral movement. Because the ends of the extension rod are respectively welded to the double-sided rack 4 and the measuring frame, when the double-sided rack 4 moves laterally, it also drives the extension rod and the measuring frame to move laterally, causing the measuring frame to drive the measuring wheel, which is rotatably coupled to it, to move laterally. Since both ends of the liquid outlet pipe are connected to the liquid storage tank and the nozzle respectively, when medical staff fill the liquid storage tank with water-soluble lubricant, the lubricant can be sprayed out through the liquid outlet pipe and the nozzle. Since the measuring wheel is located on one side of the nozzle, the water-soluble lubricant sprayed through the nozzle will adhere to the measuring wheel. When the measuring wheel and the cannula are in contact with each other and the measuring wheel is driven to rotate by the cannula, the measuring wheel can apply the water-soluble lubricant attached to its surface to the outer wall of the cannula, so that the lubricant enters the annular groove on the outer wall of the cannula. When the cannula is inside the patient's mouth, the patient's oral mucus and the water-soluble lubricant will move towards each other under the action of cohesive force, causing the water-soluble lubricant to move from the inside of the annular groove to the outside of the annular groove to cover the cannula, thereby achieving the lubrication operation of the cannula.

[0047] like Figure 2 and Figure 4 As shown, the first cannula fixing assembly includes a first piston box 6 welded to the support frame 3, and the inner wall of the first piston box 6 is slidably fitted with a first piston plate 7, and the first piston plate 7 is fixedly clamped to the output shaft of the electric telescopic rod; the first piston box 6 is connected to a first solenoid valve, and the controller is used to control the opening and closing of the first solenoid valve. The first piston box 6 is connected to a ring-shaped cannula fixing airbag 8 through the first solenoid valve, and an elastic band (not shown in the figure) is fixedly bonded to the outer wall of the cannula fixing airbag 8, and the cannula fixing airbag 8 is located outside the shell 1.

[0048] Specifically, since the first piston plate 7 is fixedly connected to the output shaft of the electric telescopic rod, when the output shaft of the electric telescopic rod contracts, it can drive the first piston plate 7 to move laterally in the first piston box 6, thereby disturbing the gas in the first piston box 6, forming an airflow, and transporting it to the interior of the cannula fixing airbag 8 through the first solenoid valve. The cannula is initially fixed by the expansion of the cannula fixing airbag 8. Figure 4 As shown, when the output shaft of the electric telescopic rod contracts, the first piston plate 7 moves in the first piston box 6 to Figure 4 The first piston box 6 moves upward, and the gas in the first solenoid valve is discharged, so that the gas is released into the cannula fixing airbag 8 through the first solenoid valve. At this time, the gas in the cannula fixing airbag 8 increases, causing the cannula fixing airbag 8 to expand.

[0049] like Figure 2As shown, the second cannula fixing assembly includes a first connecting rod 9 integrally formed on the fan-shaped tooth block 5, the first connecting rod 9 extends through the side wall of the shell 1 to the outside of the shell 1 and is hinged with a fixing rod 10, the support frame 3 is symmetrically hinged with a second connecting rod 11, the second connecting rod 11 is hinged to the adjacent fixing rod 10, the fixing rod 10 is integrally formed with a U-shaped fixing block 12, the fixing block 12 is fixedly bonded with a buffer layer, a through groove is opened on the side wall of the shell 1, the first connecting rod 9 and the second connecting rod 11 are both located in the through groove.

[0050] Specifically, since the first connecting rods 9 are integrally formed with the adjacent sector-shaped tooth blocks 5, when the sector-shaped tooth blocks 5 swing, they can drive the adjacent first connecting rods 9 to swing together. Furthermore, since the first connecting rods 9 are hingedly connected to the fixing rods 10, and the two ends of the second connecting rods 11 are respectively hingedly connected to the fixing rods 10 and the support frame 3, when the first connecting rods 9 swing, they can drive the fixing rods 10 to move laterally under the limit of the second connecting rods 11, so that the adjacent fixing rods 10 are brought closer to each other, and then the fixing blocks 12 integrally formed with them are driven to move closer to each other through the fixing rods 10, thereby further clamping and fixing the cannula.

[0051] like Figure 2 As shown, a head fixing assembly for fixing the patient's head is provided on one side of the shell 1, and the head fixing assembly is located below the second cannula fixing assembly. The shell 1 is also provided with an auxiliary fixing assembly for assisting the head fixing assembly to fix the patient's head and perform protective operations on the patient's head.

[0052] The head fixing assembly includes a fixing plate 13 welded to the bottom of the fixing rod 10 , and a head fixing airbag 14 is fixedly bonded to the fixing plate 13 .

[0053] Specifically, since the fixing plate 13 is welded to the bottom of the fixing rod 10, when the fixing rods 10 move closer to each other, the fixing plates 13 will also move closer to each other under the drive of the fixing rods 10, and then the head fixing airbags 14 on the fixing plates 13 will also move closer to each other to fix the patient's head.

[0054] like Figure 2 and Figure 3 As shown, the auxiliary fixing assembly includes a second piston box 15 symmetrically welded to the outer wall of the shell 1, and the inner wall of the second piston box 15 is slidably fitted with a second piston plate 16. A hinge rod is integrally formed on one side of the second piston plate 16, and the end of the hinge rod away from the second piston plate 16 passes through the side wall of the second piston box 15 and extends to the outside of the second piston box 15 and is hinged to the adjacent fixing rod 10; the second piston box 15 is connected to a second solenoid valve, and the controller is used to control the opening and closing of the second solenoid valve. The second piston box 15 is connected to the adjacent head fixing airbag 14 through the second solenoid valve.

[0055] Specifically, since the second piston plates 16 are integrally formed with the adjacent hinged rods, and the hinged rods are hinged to the adjacent fixed rods 10, when the fixed rods 10 move closer to each other, they can drive the second piston plates 16 to move laterally in the second piston box 15, and transport the gas in the second piston box 15 to the adjacent head fixing airbag 14 through the second solenoid valve, so that while enhancing the fixation effect on the patient's head, it reduces the direct contact between the patient's head and the fixing plate 13, thereby protecting the patient's head.

[0056] The specific implementation process is as follows:

[0057] The medical staff first fills the liquid storage tank with a water-soluble lubricant for lubricating the cannula, and then fixes the cannula fixing airbag 8 to the patient's head through an elastic band, so that the center position of the cannula fixing airbag 8 is on the same vertical line as the patient's mouth, to ensure that the cannula can be stably clamped by the cannula fixing airbag 8 after being placed in the patient's mouth. At the same time, the cannula fixing airbag 8 adaptively expands to adaptively clamp cannulas of different diameters, and enables the cannula to be vertically inserted into the patient's mouth, reducing the contact between the cannula and the patient's oral mucosa during the process of insertion into the patient's mouth, thereby reducing the irritation to the patient. During this process, the first solenoid valve and the second solenoid valve both remain in the open state. The medical staff places the cannula in the patient's mouth, and then controls the electric telescopic rod output shaft to contract through the controller, so that it drives the first piston plate 7 to move laterally in the first piston box 6, and transports the gas in the first piston box 6 to the inside of the cannula fixing airbag 8 to expand it, thereby performing a preliminary fixation operation on the cannula. As Figure 4 As shown, the output shaft of the electric telescopic rod contracts, driving the first piston plate 7 to Figure 4 The first solenoid valve releases gas from the first piston chamber 6 into the cannula-securing airbag 8, causing it to expand and secure the cannula. The medical staff then closes the first solenoid valve via a controller to ensure a constant air pressure within the cannula-securing airbag 8. During this process, the amount of air in the cannula-securing airbag 8 increases as the output shaft of the electric telescopic rod contracts, thereby improving the cannula's securing effect. Furthermore, the cannula-securing airbag 8 expands to varying degrees as its air volume changes, enabling it to stably clamp cannulae of varying diameters.

[0058] When the electric telescopic rod is retracted, it also drives the double-sided rack 4 to move horizontally, which in turn drives the fan-shaped tooth block 5 to swing, which drives the first connecting rod 9 to swing, and the first connecting rod 9 drives the fixed rod 10 to swing, causing it to move horizontally under the limit of the second connecting rod 11. At this time, the adjacent fixed rods 10 move closer to each other, driving the fixed blocks 12 to move closer to each other, further clamping and fixing the cannula. During this process, after the fixed blocks 12 move closer to each other, their fixed points on the cannula and the center position of the cannula fixing airbag 8 are located on the same vertical line, so that the fixed points of the cannula by the fixed blocks 12, the fixed points of the cannula by the cannula fixing airbag 8, and the patient's oral cavity form a straight line. At this time, when the medical staff adjusts the depth of the cannula inserted into the patient's mouth, the cannula will always maintain vertical movement. Compared with manual intubation, the cannula will shake less, thereby making the cannula less disturbing to the patient's oral mucosa, further reducing the irritation to the patient.

[0059] In this embodiment, after the cannula is placed in the patient's mouth, it comes into contact with the measuring wheel. Since the medical staff has filled the reservoir with water-soluble lubricant, the lubricant is sprayed through the outlet pipe and nozzle, adhering to the surface of the measuring wheel. As the cannula continues to penetrate the patient's mouth, it drives the measuring wheel to rotate, releasing the water-soluble lubricant adhering to its surface into the annular groove on the outer wall of the cannula. This lubricates the cannula and reduces its contact with the patient's oral mucosa during insertion. The number of rotations of the measuring wheel during this process is proportional to the insertion depth of the cannula. As the cannula depth increases, the number of rotations of the measuring wheel also increases, resulting in an increase in the amount of water-soluble lubricant applied to the outer wall of the cannula. Furthermore, the design of the measuring wheel allows medical staff to monitor the insertion depth of the cannula in real time based on the number of rotations of the measuring wheel, further improving the accuracy of cannula insertion.

[0060] When the fixing rods 10 move closer to each other, they will also drive the fixing plates 13 welded on the fixing rods 10 to move closer to each other, and then drive the head fixing airbags 14 to move closer to each other through the fixing plates 13, thereby protecting the patient's head while fixing the patient's head.

[0061] During this process, the fixation rod 10 also drives the adjacent hinged rod to move laterally, which in turn drives the second piston plate 16 to move laterally within the second piston box 15. This, in turn, releases the gas within the second piston box 15 through the second solenoid valve into the adjacent head fixation airbag 14 via the second piston plate 16. The expansion of the head fixation airbag 14 enhances the fixation effect on the patient's head. Afterwards, the medical staff closes the second solenoid valve via the controller to ensure a constant air pressure within the head fixation airbag 14.

[0062] When the cannula needs to be removed, the medical staff controls the output shaft of the electric telescopic rod to extend through the controller, and controls the first solenoid valve and the second solenoid valve to open, so that the gas in the cannula fixing airbag 8 and the gas in the head fixing airbag 14 enter the first piston box 6 and the second piston box 15 respectively through the first solenoid valve and the second solenoid valve. At this time, due to the loss of gas, the cannula fixing airbag 8 and the head fixing airbag 14 no longer expand, so that the cannula and the patient's head are no longer fixed, and the medical staff can now remove the cannula. In this process, since the gas in the cannula fixing airbag 8 is in a state of gradual loss, in the initial stage of removing the cannula, the clamping effect of the cannula fixing airbag 8 on the cannula will gradually weaken, so that the cannula fixing airbag 8 will still retain a certain limit on the cannula during this process, so that the cannula will not immediately deviate, thereby reducing the disturbance of the cannula to the patient's oral mucosa and further reducing the irritation to the patient.

[0063] The present invention fixes the patient's head through a head fixing assembly, which can effectively reduce the impact of the patient's head shaking on the intubation, so that the intubation can always be kept in the correct airway position, reducing the risk of intubation displacement due to patient head movement and causing irritation to the patient.

[0064] Example 2:

[0065] The difference from embodiment 1 is that a rubber layer is fixedly bonded to both the first piston plate 7 and the second piston plate 16 .

[0066] The specific implementation process is as follows: when the first piston plate 7 and the second piston plate 16 move laterally in the first piston box 6 and the second piston box 15, thanks to the elastic sealing design of the rubber layer, the gap between the first piston plate 7 and the inner wall of the first piston box 6, and the gap between the second piston plate 16 and the inner wall of the second piston box 15 can be filled by the rubber layer, thereby enabling the first piston plate 7 and the second piston plate 16 to better disturb the gas during movement, thereby improving the operating stability of the first piston plate 7 and the second piston plate 16.

[0067] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
