Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and specifically relates to a multifunctional anesthesia device for use in anesthesiology. Background Technology

[0002] Anesthesia, as a medical procedure, aims to achieve reversible functional inhibition of the central and peripheral nervous systems through the application of specific drugs or other advanced technologies. The core feature of this ingenious process is that it can significantly weaken or even eliminate the patient's sensory abilities, especially pain, thereby providing the patient with a crucial comfort experience during treatment or surgery.

[0003] When using a mask to administer nebulized anesthesia to patients, the required anesthetic dosage varies depending on the patient's body size, and simply spraying nebulized medication cannot be suitable for patients of different body types.

[0004] Therefore, it is necessary to invent a multifunctional anesthesia device for use in anesthesiology departments to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a multifunctional anesthesia device for use in anesthesiology departments, thereby resolving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional anesthesia device for anesthesiology, comprising: a mask covering the outside of the patient's mouth and nose; two connecting tubes connected by an intermediate tube, with the bottoms of the two connecting tubes connected to the mask via trachea for introducing nebulized anesthetic and oxygen into the mask; two ventilation tubes corresponding one-to-one with the two connecting tubes; an arc-shaped plate rotatably inserted into the surface of the connecting tubes; and a rotating component comprising: a rotating rod rotatably inserted into the intermediate tube; a swing plate installed at the rear end of the rotating rod; and a square-round rod corresponding to and passing through the arc-shaped plate for driving the arc-shaped plate to rotate inside the connecting tubes.

[0007] Furthermore, a round rod is fixed to the front end of the rotating rod, and teeth are fixed to the rear side of the round rod. Multiple tooth grooves are provided on the front side of the intermediate tube, and the teeth are snapped into the tooth grooves.

[0008] Furthermore, a rotating groove corresponding to the swing plate is provided on the rear side of the outer circumference of the intermediate tube, and the rotating rod causes the swing plate to rotate inside the rotating groove.

[0009] Furthermore, a circular plate is fixed to the front end of the square-round rod, and a nut is screwed onto the center of the square-round rod. An elastic element is provided between the nut and the arc-shaped plate. The elastic element is sleeved on the surface of the square-round rod, and the front end of the elastic element is connected to the rear side of the arc-shaped plate.

[0010] Furthermore, the rear end of the elastic element abuts against the front side of the nut, and the elastic force of the elastic element causes the rotating rod to move backward inside the intermediate tube through the nut.

[0011] Furthermore, the arc-shaped plate has side grooves on both sides of its rear side, and a sliding plate is installed inside the side groove. The sliding plate is mounted on the arc-shaped plate using a sliding component.

[0012] Furthermore, the cross-section of the slide plate is larger than the inner diameter of the vent pipe, which is used to block the vent pipe.

[0013] Furthermore, the sliding component includes: an arc-shaped strip and a screw; both ends of the arc-shaped strip are fixed with sliding plates, and a screw is spirally inserted into the center of the arc-shaped strip. The outer circumference of the arc-shaped plate is provided with a curved groove corresponding to the arc-shaped strip, and the rotating arc-shaped strip rotates inside the curved groove.

[0014] Furthermore, the end of the curved groove corresponds to a single side groove, and the curved groove is connected to the side groove.

[0015] Furthermore, the bottom end of the screw passes through the center of the arc-shaped strip, and the bottom end of the screw corresponds to the curved groove.

[0016] The technical effects and advantages of this invention are as follows: 1. This invention uses the compression of the screw and the curved groove to conveniently limit the slide plate inside the side groove. The degree to which the slide plate blocks the airway can be adjusted according to the patient's needs, and the mixing ratio of the atomized gas inside the mask can be easily adjusted so that the atomized gas can anesthetize patients of different body types.

[0017] 2. The present invention uses the elastic force of the elastic element to make the teeth and grooves on the rear side of the round rod engage, which makes it easy to limit the arc plate to different positions inside the connecting tube, making it easy for the arc plate to block the air tube, and enabling the atomized anesthetic or oxygen to be introduced into the connecting tube separately.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] This invention provides a multifunctional anesthesia device for use in anesthesiology departments, such as... Figure 1 and Figure 2 As shown, it includes: a mask 1, a connecting tube 2, an trachea 3, and a ventilation tube 4; two connecting tubes 2 are arranged side by side and connected by an intermediate tube 201. The bottom of the front end of each of the two connecting tubes 2 is connected to the mask 1 by the trachea 3. The mask 1 is shaped like a frustum. The rear end of the connecting tube 2 is connected to the ventilation tube 4. There are two ventilation tubes 4, and each ventilation tube 4 corresponds to one of the two connecting tubes 2. Nebulized anesthetic and oxygen are respectively introduced into the two connecting tubes 2.

[0021] Specifically, a spring clip is connected to the mask 1, which allows the bottom opening of the mask 1 to cover the outside of the patient's mouth and nose. Two connecting tubes 2 are connected to the nebulizer and the oxygen cylinder respectively via the ventilation tube 4. At this time, the oxygen cylinder introduces oxygen into the connecting tube 2 through the ventilation tube 4, and the nebulizer introduces nebulized anesthetic into the other connecting tube 2 through the ventilation tube 4. The nebulized anesthetic and oxygen are mixed through the trachea 3, and the mixed nebulized gas diffuses inside the mask 1, making it convenient for the patient to inhale the nebulized gas through their mouth and nose, thus facilitating the anesthesia treatment.

[0022] The rate at which nebulized anesthetic and oxygen are continuously passed through the ventilation tube 4 remains constant.

[0023] To seal the connecting pipe 2, a rotating component is used to rotate the arc-shaped plate 5. Figures 1 to 4 In the middle, the rotating components include: a rotating rod 6, a swing plate 7, a square-round rod 8, a round rod 9, a round plate 10, a nut 11, and an elastic element 12, the elastic element 12 being a spring; the top surface of the connecting pipe 2 has a slot corresponding to the arc plate 5, the end of the arc plate 5 is inserted into the inside of the connecting pipe 2 through the slot, the square-round rod 8 is inserted into the center of the arc plate 5, the front end of the square-round rod 8 is fixed with a round plate 10, the rear end of the square-round rod 8 is connected to the rear end of the rotating rod 6 by the swing plate 7, the rotating rod 6 is rotatably inserted into the inside of the intermediate pipe 201, and the rear side of the outer circumference of the intermediate pipe 201 is provided with a rotating groove 203 corresponding to the swing plate 7, the rotating rod 6 causes the swing plate 7 to rotate inside the rotating groove 203.

[0024] A nut 11 is screwed onto the surface of the square-round rod 8. An elastic element 12 is provided between the nut 11 and the arc-shaped plate 5. The elastic element 12 is sleeved on the surface of the square-round rod 8, and the front end of the elastic element 12 is connected to the rear side of the arc-shaped plate 5. The rear end of the elastic element 12 abuts against the front side of the nut 11. The elastic force of the elastic element 12 causes the rotating rod 6 to move backward inside the intermediate tube 201 through the nut 11. A round rod 9 is fixed to the front end of the rotating rod 6. A tooth 901 is fixed to the rear side of the round rod 9. Multiple tooth grooves 202 are provided on the front side of the intermediate tube 201. The elastic force of the elastic element 12 causes the tooth 901 to engage inside the tooth grooves 202.

[0025] Specifically, rotating the round rod 9 causes the toothed rod 901 to rotate out of the toothed groove 202. The rotating toothed rod 901 uses the toothed groove 202 to move the round rod 9 away from the intermediate tube 201. During the rotation of the round rod 9, the rotating rod 6 rotates inside the intermediate tube 201. When the rotating rod 6 causes the swing plate 7 to rotate inside the rotating groove 203, the swing plate 7 uses the square-round rod 8 to make the arc plate 5 rotate. At this time, the arc plate 5 rotates inside the connecting tube 2 using the slot.

[0026] The forward-moving round rod 9 uses the rotating rod 6 to cause the swing plate 7 to move forward inside the rotating groove 203. The forward-moving swing plate 7 causes the square-round rod 8 to move forward at the center of the arc plate 5. The forward-moving square-round rod 8 uses the nut 11 to squeeze the elastic element 12. When the rotating tooth 901 corresponds to the next tooth groove 202, the elastic force of the elastic element 12 causes the square-round rod 8 to move backward through the nut 11. At this time, the square-round rod 8 uses the swing plate 7 and the rotating rod 6 to cause the round rod 9 to move backward. The backward-moving round rod 9 causes the tooth 901 to engage with the tooth groove 202.

[0027] The arc-shaped plate 5 rotates inside the connecting tube 2 using a slot. When the arc-shaped plate 5 corresponds to the air vent 4 of the connecting tube 2, the arc-shaped plate 5 blocks the air vent 4, allowing nebulized anesthetic or oxygen to be introduced into the connecting tube 2 independently.

[0028] In this embodiment, the elastic force of the elastic member 12 causes the teeth 901 on the rear side of the round rod 9 to engage with the tooth groove 202, which facilitates the confinement of the arc plate 5 at different positions inside the connecting pipe 2, making it convenient for the arc plate 5 to block the ventilation pipe 4, and enabling the atomized anesthetic or oxygen to be introduced into the connecting pipe 2 separately.

[0029] To adjust the degree to which the curved plate 5 blocks the vent pipe 4, the sliding plate 13 is used in conjunction with the sealing of the vent pipe 4. Figures 3 to 5In the arc-shaped plate 5, side grooves 501 are provided on both sides of the rear side. A sliding plate 13 is installed inside the side groove 501. The cross-section of the sliding plate 13 is larger than the inner diameter of the vent pipe 4. The sliding plate 13 is mounted on the arc-shaped plate 5 using sliding components. The sliding components include an arc-shaped strip 14 and a screw 15. Sliding plates 13 are fixed to both ends of the arc-shaped strip 14, and a screw 15 is spirally inserted into the center of the arc-shaped strip 14. A curved groove 502 corresponding to the arc-shaped strip 14 is provided on the outer circumference of the arc-shaped plate 5. The rotating arc-shaped strip 14 rotates inside the curved groove 502. The end of the curved groove 502 corresponds to a single side groove 501, and the curved groove 502 is connected to the side groove 501. The bottom end of the screw 15 passes through the center of the arc-shaped strip 14, and the bottom end of the screw 15 corresponds to the curved groove 502.

[0030] Specifically, when the elastic force of the elastic element 12 causes the tooth 901 to engage inside the tooth groove 202, the screw 15 is loosened. At this time, the connecting pipe 2 uses the slot to limit the arc-shaped strip 14 inside the bend 502. The arc-shaped strip 14 rotates inside the bend 502, causing the slide plate 13 to rotate inside the side groove 501. When the slide plate 13 on the left side moves downward inside the side groove 501, the slide plate 13 on the right side moves upward inside the side groove 501; similarly, when the slide plate 13 on the right side moves downward inside the side groove 501, the slide plate 13 on the left side moves upward inside the side groove 501.

[0031] When the two ends of the arc plate 5 correspond to the two ventilation pipes 4 respectively, both ventilation pipes 4 can introduce atomized anesthetic and oxygen into the connecting pipe 2. Rotating the arc strip 14 causes the slide plate 13 to move inside the side groove 501. Tightening the screw 15 causes the bottom end of the screw 15 to press against the inner wall of the curved groove 502, thereby limiting the arc strip 14. This allows for adjustment of the degree to which the slide plate 13 blocks the ventilation pipes 4, making it convenient to adjust the mixing ratio of the atomized gas inside the mask 1.

[0032] In this embodiment, the screw 15 and the curved groove 502 squeeze and limit the slide plate 13 inside the side groove 501, which can be adjusted according to the patient's needs to block the airway 4. This allows for easy adjustment of the mixing ratio of the atomized gas inside the mask 1, so that the atomized gas can anesthetize patients of different body types.

[0033] Working principle of this invention: Reference Figures 1 to 5 As shown, rotating the round rod 9 causes the rotating round rod 9 to rotate out of the tooth groove 202 using the teeth 901. The rotating teeth 901 use the tooth groove 202 to make the round rod 9 move away from the intermediate tube 201. During the rotation of the round rod 9, the rotating rod 6 rotates inside the intermediate tube 201. When the rotating rod 6 causes the swing plate 7 to rotate inside the rotating groove 203, the swing plate 7 uses the square-round rod 8 to make the arc plate 5 rotate. At this time, the arc plate 5 rotates inside the connecting tube 2 using the slot.

[0034] The forward-moving round rod 9 uses the rotating rod 6 to cause the swing plate 7 to move forward inside the rotating groove 203. The forward-moving swing plate 7 causes the square-round rod 8 to move forward at the center of the arc plate 5. The forward-moving square-round rod 8 uses the nut 11 to squeeze the elastic element 12. When the rotating tooth 901 corresponds to the next tooth groove 202, the elastic force of the elastic element 12 causes the square-round rod 8 to move backward through the nut 11. At this time, the square-round rod 8 uses the swing plate 7 and the rotating rod 6 to cause the round rod 9 to move backward. The backward-moving round rod 9 causes the tooth 901 to engage with the tooth groove 202.

[0035] When the elastic force of the elastic element 12 causes the tooth 901 to engage inside the tooth groove 202, the screw 15 is loosened. At this time, the connecting pipe 2 uses the slot to limit the arc strip 14 inside the bend 502. The arc strip 14 rotates inside the bend 502, causing the slide plate 13 to rotate inside the side groove 501. When the left slide plate 13 moves downward inside the side groove 501, the right slide plate 13 moves upward inside the side groove 501; similarly, when the right slide plate 13 moves downward inside the side groove 501, the left slide plate 13 moves upward inside the side groove 501.

[0036] When the two ends of the arc plate 5 correspond to the two ventilation pipes 4 respectively, both ventilation pipes 4 can introduce atomized anesthetic and oxygen into the connecting pipe 2. Rotating the arc strip 14 causes the slide plate 13 to move inside the side groove 501. Tightening the screw 15 causes the bottom end of the rotating screw 15 to press against the inner wall of the curved groove 502, thereby limiting the arc strip 14 and adjusting the degree to which the slide plate 13 blocks the ventilation pipe 4.

[0037] A spring clip is attached to the mask 1, which allows the bottom opening of the mask 1 to cover the outside of the patient's mouth and nose. Two connecting tubes 2 are connected to the nebulizer and the oxygen cylinder respectively via the ventilation tube 4. At this time, the oxygen cylinder introduces oxygen into the connecting tube 2 through the ventilation tube 4, and the nebulizer introduces nebulized anesthetic into the other connecting tube 2 through the ventilation tube 4. The nebulized anesthetic and oxygen are mixed through the trachea 3, and the mixed nebulized gas diffuses inside the mask 1, making it convenient for the patient to inhale the nebulized gas through their mouth and nose, thus facilitating the anesthesia treatment.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
