Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of oropharyngeal ventilation anesthesia, in particular to an inhalation type oropharyngeal ventilation anesthesia device for anesthesiology. Background Art
[0002] Inhalational oropharyngeal ventilation anesthesia is achieved through mechanical upper airway support combined with the central nervous system inhibitory effects of inhaled anesthetics. The procedure should always be performed with gentleness, precision, and monitoring to avoid complications.
[0003] Currently, before performing inhalation oropharyngeal ventilation anesthesia, the anesthesia tube needs to be placed in the patient's throat. During the operation, the tongue is usually pressed down with a tongue depressor before the tube is inserted. During this process, a support structure needs to be inserted to ensure that the mouth and pharynx are open, which makes the operation before anesthesia complicated. At the same time, it is difficult to control the strength of manual pressure and insertion of the support structure, which can easily cause damage to the patient's mouth. At the same time, during the ventilation anesthesia process, the patient's oral cavity near the pharynx will physiologically secrete fluid. The fluid secreted by the oral cavity has a certain viscosity. If more fluid is concentrated in the pharynx of the patient's mouth, it will hinder the introduction of anesthetic gas, thereby affecting the overall anesthesia effect, thereby increasing the risk of surgery. Therefore, an inhalation oropharyngeal ventilation anesthesia device for anesthesia is proposed. Summary of the Invention
[0004] The purpose of the present invention is to solve the problems in the prior art and to propose an inhalation type oropharyngeal ventilation anesthesia device for anesthesiology.
[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0011] Preferably, the retaining assembly includes a locking seat and two telescopic plates, the end of the combined bracket is fixedly connected to one end of the telescopic plate, and the other end of the telescopic plate is rotatably connected to the end surface of the locking seat.
[0012] Preferably, a locking button is fixedly connected to one end of the telescopic plate, and two limit bars are fixedly connected to both ends of the locking seat, and the limit bars on both ends of the locking seat are respectively located at the top and the bottom.
[0013] Preferably, the side wall of the sliding seat is provided with a groove adapted to the front end of the oral support plate, the suction cavity on the oral support plate is located at the front end, the front side wall of the oral support plate is made of sponge material, and the base of the oral support plate is made of soft rubber material.
[0014] Preferably, the attraction component includes an attraction electromagnetic plate and an attraction piston plate. The space above the storage chamber is communicated with the negative pressure chamber. A control power supply is provided outside the negative pressure chamber. The control power supply is electrically connected to the attraction electromagnetic plate. The inner side wall of the negative pressure chamber is slidingly connected to the attraction piston plate. The attraction piston plate is connected to an adjustment magnetic plate opposite to the attraction electromagnetic plate. The attraction piston plate is fixedly connected to the inner end face of the negative pressure chamber through two reset telescopic rods.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. This solution uses the setting of the slide and the oral support plate to slowly advance the flat tube by pressing it in, and gradually increase the downward pressure on the tongue by using the oral support plate below to avoid damage to the tongue or oral mucosa caused by sudden pressure. During the pushing process, the oral support plate continuously presses down the tongue, expanding the field of vision of the throat, making it easier to observe the tube insertion path and improving the operation accuracy.
[0017] 2. Through the setting of the oral support plate and the retention component, this solution can utilize the rotation changes of the oral support plate in the oral cavity to change the support space of the oral support plate in the oral cavity, and allow the two combined brackets to achieve fixed limit when the support angle is reached, thereby ensuring the stability of the support structure of the two oral support plates, reducing the risk of tissue damage caused by one-time strong support of traditional instruments, and reducing iatrogenic injuries.
[0018] 3. This solution uses the suction component to quickly generate a negative pressure state through electromagnetic control, which can promptly attract secretions from the throat, prevent viscous liquid from accumulating and blocking the airway, and ensure smooth ventilation. The suction channel is directly connected to the storage cavity and can be disassembled and cleaned after surgery to reduce the risk of cross infection.
[0019] 4. This solution uses the setting of the limit release component to automatically unlock the limit structure by releasing the push rod when removing the pressed flat tube, simplifying the instrument withdrawal process and avoiding secondary damage. The oral support plate is removed synchronously with the pressed flat tube, reducing residual risks, shortening postoperative operation time, and realizing an integrated withdrawal mechanism.

For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances.
[0032] Example, see Figures 1 to 8 An inhalation type oropharyngeal ventilation anesthesia device for anesthesiology comprises a press-in flat tube 1 and two oral support plates 2. The top and bottom ends of the press-in flat tube 1 are fixedly connected to a guide rail 3. The inner side wall of the guide rail 3 is connected to a bringing-in slide 6 through a limiting component. Both sides of the bringing-in slide 6 located above are connected to a release component.
[0033] Furthermore, the limiting component is composed of a limiting bar 4 and two limiting telescopic rods 5. The inner side wall of the guide track 3 is fixedly connected to the limiting bar 4. The side wall of the limiting bar 4 is fixedly connected to the bringing-in slide 6 through the two limiting telescopic rods 5. The bringing-in slide 6 is slidably connected to the inner side wall of the guide track 3. The limit release component includes a propulsion bent rod 7. The top ends of the bringing-in slide 6 located above are respectively fixedly connected to the two propulsion bent rods 7. The end of the propulsion bent rod 7 is fixedly connected to a release push rod 8.
[0034] It should be noted that: the external ventilation structure is connected to the end of the pressed flat tube 1 away from the brought-in slide 6. The external ventilation structure of the pharyngeal ventilation anesthesia device is an existing technical means and will not be described in detail here. Subsequently, when the pressed flat tube 1 is placed in the patient's throat, one end of the brought-in slide 6 is used as the pushing end, and the lower oral support plate 2 is placed above the patient's tongue. Then, the pressed flat tube 1 is slowly pushed toward the patient's throat. During the pushing process, the lower oral support plate 2 will continuously press down the patient's tongue, thereby gradually increasing the downward pressure on the patient's tongue and avoiding damage caused by sudden artificial pressure on the patient's tongue.
[0035] The advantages of the above are as follows: before ventilation anesthesia, the flat tube 1 can be directly pushed into the patient's throat, and during the pushing process, the oral support plate 2 below is used to continuously press down the patient's tongue, so that the flat tube 1 can be pushed in with a better field of view;
[0036] The inner wall of the guide rail 3 is connected to the oral support plate 2 through the compensation slide 9. The two side walls of the oral support plate 2 are fixedly connected to the combined bracket 13 through the pin 11. The upper and lower opposite ends of the combined bracket 13 are connected together by a retaining assembly.
[0037] Furthermore, the inner side wall of the guide rail 3 is slidably connected to the compensation slide 9, and the ends of the compensation slide 9 are rotatably connected to the two pins 11 through two fixed plates 10. The outer side wall of the pin 11 is sleeved with a torsion spring 12. The retaining assembly includes a locking seat 16 and two telescopic plates 14. The end of the combined bracket 13 is fixedly connected to one end of the telescopic plate 14, and the other end of the telescopic plate 14 is rotatably connected to the end surface of the locking seat 16. A locking button 15 is fixedly connected to one end of the telescopic plate 14. Two limit bars 17 are fixedly connected to both ends of the locking seat 16. The limit bars 17 on both ends of the locking seat 16 are respectively located at the top and bottom;
[0038] It should be noted that: in the process of continuous advancement of the pressed flat tube 1, due to the increase in friction between the upper and lower oral support plates 2 and the patient's oral palate and tongue, the friction between the oral support plates 2 and the grooves of the brought-in slide 6 will be used to allow the brought-in slide 6 to continuously compress the limiting telescopic rod 5. As the thrust of the limiting telescopic rod 5 on the brought-in slide 6 continues to increase, the brought-in slide 6 tends to synchronize with the movement of the guide rail 3, thereby separating the brought-in slide 6 from the oral support plate 2. At this time, the brought-in slide 6 will bring the two oral support plates 2 to the part of the oral cavity that needs support, and then use tweezers to simultaneously press the outward ends of the two oral support plates 2 toward the middle of the oral cavity. The rotation of the oral support plates 2 will drive the combined bracket 13 to rotate through the pin shaft 11, and the combined bracket 13 will rotate. The rotation of the combined bracket 13 will rotate the telescopic plate 14, causing the telescopic plate 14 to rotate on the locking seat 16. After the locking button 15 on the telescopic plate 14 rotates to between the two limit bars 17, the locking button 15 is limited (when the locking button 15 contacts and presses on the limit bar 17, the end of the telescopic plate 14 will have a slight elastic deformation. After rotating past the limit bar 17, the elastic deformation of the end of the telescopic plate 14 is restored, so that the locking button 15 is limited by the two limit bars 17), thereby achieving fixed limitation between the two combined brackets 13, completing the structural support for the patient's oral cavity, and gradually pressing the opening support to avoid causing greater damage to the patient's oral cavity as much as possible, making tongue pressing observation and oral support safer;
[0039] The above advantages are as follows: the rotation of the oral support plate 2 in the oral cavity can be utilized to change the support space of the oral support plate 2 in the oral cavity, and when the support angle is reached, the two combined brackets 13 can be fixed and limited, thereby ensuring the stability of the support structure of the two oral support plates 2, making the pipeline placement and preparation work before the anesthesia operation more efficient and safer;
[0040] The two oral support plates 2 are arranged at an angle. The back sides of the oral support plates 2 are connected to the storage chamber 18 and the negative pressure chamber 19 respectively. The end of the oral support plate 2 located on the side where the slide 6 is brought in is provided with a suction cavity. The suction cavity is provided with multiple suction channels for communicating with the storage chamber 18 and the negative pressure chamber 19. A suction component is provided in the negative pressure chamber 19.
[0041] Furthermore, a groove is provided on the side wall of the sliding seat 6 to match the front end of the oral support plate 2. The suction cavity on the oral support plate 2 is located at the front front end. The front side wall of the oral support plate 2 is made of sponge material, and the base of the oral support plate 2 is made of soft rubber material. The suction component includes an suction electromagnetic plate 21 and a suction piston plate 23. The space above the storage chamber 18 is connected to the negative pressure chamber 19. A control power supply 20 is provided outside the negative pressure chamber 19. The control power supply 20 is electrically connected to the suction electromagnetic plate 21. The inner wall of the negative pressure chamber 19 is slidably connected to the suction piston plate 23. The suction piston plate 23 is connected to an adjustment magnetic plate 22 opposite to the suction electromagnetic plate 21. The suction piston plate 23 is fixedly connected to the inner end face of the negative pressure chamber 19 through two reset telescopic rods 24.
[0042] It should be noted that: during the anesthesia process, if the anesthesia personnel observes that the patient's oral and pharyngeal secretions are produced, or the anesthesia device detects that there is resistance to airway access, the control power supply 20 can be turned on to energize the attraction electromagnetic plate 21. After the attraction electromagnetic plate 21 is energized, the magnetism generated will magnetically attract the adjustment magnetic plate 22, and the adjustment magnetic plate 22 will quickly drive the attraction piston plate 23 to compress and reset the telescopic rod 24 to move in the direction of the attraction electromagnetic plate 21. The movement of the attraction piston plate 23 will cause the negative pressure chamber 19 to be in a short-term negative pressure state, and then the storage chamber 18 and the connected suction channel will be in a short-term negative pressure state, and the oral support plate 2 will attract the secretion liquid outside the oral cavity. The attracted secretion liquid will be sucked away. The suction channel enters the storage cavity 18, which is convenient for disassembly and cleaning after surgery. It should be noted that when the oral support plate 2 rotates to support the patient's oral cavity, the end of the oral support plate 2 with the suction cavity will also rotate to contact the upper and lower sides of the patient's throat. After anesthesia is completed, when the flat tube 1 is pressed in and moved outward, the sliding seat 6 will be driven to move outward together, and the release push rod 8 will be driven to move by the pushing bent rod 7, so that the release push rod 8 pushes the locking seat 16, so that the locking seat 16 and the telescopic plate 14 rotate, thereby prompting the locking button 15 to rotate out of the two limit bars 17, releasing the fixed limit of the two combined brackets 13, so that the two oral support plates 2 and the pressed flat tube 1 can be moved out synchronously;
[0043] The benefits of the above are: this can facilitate the effective suction of the secretions in the throat when they are produced, and avoid the accumulation of viscous secretions during anesthesia, which may block the throat passage and affect the anesthesia effect;
[0044] When the present invention is in use, the external ventilation structure is connected to the end of the pressed flat tube 1 away from the brought-in slide 6. The external ventilation structure of the pharyngeal ventilation anesthesia device is an existing technical means and will not be described in detail here. Subsequently, when the pressed flat tube 1 is placed on the patient's throat, one end of the brought-in slide 6 is used as the pushing end, and the lower oral support plate 2 is allowed to be located above the patient's tongue. Then, the pressed flat tube 1 is slowly pushed toward the patient's throat. During the pushing process, the lower oral support plate 2 will continuously press down the patient's tongue, thereby gradually increasing the downward pressure on the patient's tongue and avoiding damage caused by sudden artificial pressure on the patient's tongue. In this way, the pressed flat tube 1 can be directly pushed into the patient's throat before ventilation anesthesia, and the lower oral support plate 2 can be used to continuously press down the patient's tongue during the pushing process, so that the pressed flat tube 1 can have a better observation field during the pushing process.
[0045] As the flat tube 1 is continuously pushed forward, the friction between the upper and lower oral support plates 2 and the patient's oral palate and tongue increases, and the friction between the oral support plates 2 and the grooves of the introduction slide 6 is used to allow the introduction slide 6 to continuously compress the limiting telescopic rod 5. As the thrust of the limiting telescopic rod 5 on the introduction slide 6 continues to increase, the introduction slide 6 tends to synchronize with the movement of the guide rail 3, thereby separating the introduction slide 6 from the oral support plate 2. At this time, the introduction slide 6 will bring the two oral support plates 2 to the part of the oral cavity that needs support, and then use tweezers to simultaneously press the outward ends of the two oral support plates 2 toward the middle of the oral cavity. The rotation of the oral support plate 2 will drive the combined bracket 13 to rotate through the pin shaft 11, and the rotation of the combined bracket 13 will cause the telescopic plate 14 to rotate, so that the telescopic plate 14 rotates on the locking seat 16, and the locking button 15 on the telescopic plate 14 is turned to the two limit bars 17. After that, the locking button 15 is limited (when the locking button 15 contacts and presses on the limiting strip 17, the end of the telescopic plate 14 will have a slight elastic deformation. After the limiting strip 17 is rotated, the elastic deformation of the end of the telescopic plate 14 is restored, so that the locking button 15 is limited by the two limiting strips 17), thereby achieving fixed limitation between the two combined brackets 13, completing the structural support for the patient's oral cavity, gradually pressing the opening support, and avoiding as much damage to the patient's oral cavity as possible, making the tongue pressing observation and oral support safer. In this way, the rotation change of the oral support plate 2 in the oral cavity can be used to change the support space of the oral support plate 2 in the oral cavity, and when the support angle is reached, the two combined brackets 13 can be fixed and limited, ensuring the stability of the support structure of the two oral support plates 2, making the pipeline insertion and preparation work before the anesthesia operation more efficient and safer;
[0046] During the anesthesia process, if the anesthesia personnel observes that the patient's oral and pharyngeal secretions are produced, or the anesthesia device detects that there is resistance to airway access, the control power supply 20 can be turned on to energize the attraction electromagnetic plate 21. After the attraction electromagnetic plate 21 is energized, the magnetism generated will magnetically attract the adjustment magnetic plate 22, and the adjustment magnetic plate 22 will quickly drive the attraction piston plate 23 to compress and reset the telescopic rod 24 to move in the direction of the attraction electromagnetic plate 21. The movement of the attraction piston plate 23 will cause the negative pressure chamber 19 to briefly be in a negative pressure state, and then the storage chamber 18 and the connected suction channel will be in a short negative pressure state, and the oral support plate 2 will attract the secretion liquid outside the oral cavity. The attracted secretion liquid enters the storage chamber 18 along the suction channel, which is convenient for disassembly and cleaning after surgery. Special explanation is needed. Yes, when the oral support plate 2 rotates to support the patient's mouth, the end of the oral support plate 2 with the suction cavity will also rotate to contact the upper and lower sides of the patient's throat. After the anesthesia is completed, when the flat tube 1 is pressed in and moved outward, the sliding seat 6 will be driven to move outward together, and the release push rod 8 will be driven to move by pushing the bent rod 7, so that the release push rod 8 pushes the locking seat 16, causing the locking seat 16 and the telescopic plate 14 to rotate, thereby prompting the locking button 15 to rotate out from the two limit bars 17, releasing the fixed limit of the two combined brackets 13, and facilitating the synchronous removal of the two oral support plates 2 and the pressed in flat tube 1. This can facilitate the effective suction of the secretion liquid in the throat when it is produced, and avoid the accumulation of secretion liquid with a certain viscosity during the anesthesia process, causing blockage of the throat passage and affecting the anesthesia effect.
[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
