Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, it relates to a multifunctional anesthesia machine for surgery. Background Art

[0002] Anesthesia machines are the core equipment for implementing general anesthesia and assisted respiration. The development of its technology stems from the continuous demand for surgical safety and anesthesia accuracy. Early anesthesia devices mainly achieved the delivery of anesthetic gases through simple gas mixing and delivery systems. With the progress of mechanical engineering, fluid mechanics, and electronic control technologies, anesthesia machines have gradually evolved into sophisticated systems integrating gas supply, evaporation, circulation, and monitoring functions. Modern anesthesia machines integrate medical gases such as oxygen, air, and nitrogen through a gas supply unit, use a dedicated evaporator to convert liquid anesthetic agents into gas mixtures with controllable concentrations, and cooperate with a breathing circuit to precisely regulate the inhaled gases of patients.

[0003] During the operation of the gas supply system, due to the differences in physical properties, oxygen, air, and anesthetic gases are prone to form stratified flow. Especially at low flow rates, gases with higher densities tend to deposit at the bottom of the pipeline, while gases with lower densities are distributed in the upper layer, forming a laminar flow effect that hinders the uniform mixing of multi-component gases. At the same time, the complex multi-stage pipeline structure inside the anesthesia machine may cause insufficient local turbulence intensity or unbalanced flow resistance due to factors such as bending angles and sudden changes in pipe diameters, further exacerbating the concentration gradient of the mixed gas during transmission. For this reason, we propose a multifunctional anesthesia machine for surgery. Summary of the Invention

[0011] Preferably, the offset member includes sliding grooves formed in a circular pattern on the upper end surface of the bottom end of the cavity. The adjacent two groups of sliding grooves are symmetrically arranged. The adjacent two groups of sliding grooves intersect. The angle between the adjacent two groups of sliding grooves is an obtuse angle. Multiple groups of sliding plates are slidably connected in the corresponding sliding grooves.

[0012] Preferably, the intermittent member includes a circular plate disposed on the inner wall of the movable groove. A sleeve is arranged at the bottom end of the circular plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the promoting plate guides the gas to form a downward turbulent motion. This multi-directionally disturbed air flow pattern breaks the stratification trend of oxygen and anesthetic gas in the laminar flow state, enabling the two gases to fully collide, penetrate, and fuse within a limited space. At the same time, the folding plates distributed on the surface of the promoting plate further enhance the shear force and diffusion effect of the air flow, not only significantly improving the mixing uniformity but also effectively reducing the concentration fluctuation caused by the difference in gas specific gravity, ensuring that the output mixed gas has high stability.

[0016] 2. In the present invention, the rotating rod drives the rotating block to rotate. A wave groove is provided on the outer wall of the rotating block. The wave groove is composed of a lowest section, a highest section, and an arc section. A spoiler is movably connected inside its through port. Through the wave groove, the spoiler can stably tilt up and down inside the through port, further breaking the stratification trend of oxygen and anesthetic gas in the laminar flow state and having a better mixing effect.

[0017] 3. In the present invention, the auxiliary component adjusts the connection between the mixing chamber and the cavity. When the connection between the mixing chamber and the cavity shrinks, the pressure inside the cavity rises, and the mixing contact time of oxygen and anesthetic gas is prolonged. When the connection between the mixing chamber and the cavity expands, the output of the mixed gas is accelerated, the residence time in the cavity is reduced, and the risk of excessive accumulation of high-concentration anesthetic is avoided. Thus, through continuous opening changes, the further fusion of oxygen and anesthetic gas is achieved.

[0018] 4. In the present invention, the rotating rod drives six arc-shaped plates to rotate, thereby disturbing the anesthetic gas and oxygen in the vortex region, forcing the anesthetic gas and oxygen to experience multiple accelerations, decelerations, and direction mutations in the spiral travel path. When the mixed gas flows through, the arc surface not only generates a controllable turbulent effect but also induces the gas to perform a reciprocating swirling motion in three-dimensional space through the vortex cavity formed between the plates, further enhancing the stability of the mixed gas.

Detailed implementation manners

[0021] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings of the specification.

[0022] In the following description, numerous specific details are set forth to facilitate a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0023] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate from or mutually exclusive of other embodiments selectively.

[0024] Embodiment 1 further illustrates a multifunctional anesthesia machine proposed by the present invention for surgery, including an anesthesia machine main body 100 and an evaporator 101. An intake pipe 102 is connected to the outlet end of the evaporator 101. A cavity 103 is formed inside the intake pipe 102. A promoting plate 104 is fixedly installed inside the cavity 103. The promoting plate 104 adopts a spiral guide vane with a continuous spiral curved surface configuration. The promoting plate 104 forms a turbulent flow of the mixture of oxygen and anesthetic gas downward. A mixing plate 105 is provided at the bottom end of the intake pipe 102. A mixing cavity 106 is formed inside the mixing plate 105. The mixing cavity 106 communicates with the cavity 103. A stirring assembly 200 for promoting the mixing of oxygen and anesthetic gas is provided inside the mixing cavity 106. The stirring assembly 200 includes a support member 201 provided inside the cavity 103, a rotating member 202 provided inside the support member 201, and a flow disturbing member 203 also provided inside the support member 201; In the anesthesia machine main body 100, due to the laminar flow phenomenon caused by the differences in gas flow rate and density, or the change in pipeline resistance, it can hinder the full turbulent mixing of gases, resulting in local concentration differences. Since the oxygen concentration and concentration are uneven, it may cause the actual dose of anesthetic inhaled by the patient to deviate from the set value, which has an adverse impact on the patient's surgery; By integrating the structures of the evaporator 101, the intake pipe 102, and the promoting plate 104 in the cavity 103, this device achieves the efficient mixing and stable delivery of oxygen and anesthetic gas. After the evaporator 101 converts the liquid anesthetic into a gaseous anesthetic with a controllable concentration, the intake pipe 102 connected to its outlet end guides the gas into the cavity 103. At this time, the promoting plate 104 arranged inside the cavity 103, through its specially designed inclined angle and surface flow guiding structure, guides the gas to form a downward turbulent motion. This multi-directionally disturbed air flow pattern breaks the stratification trend of oxygen and anesthetic gas in the laminar flow state, enabling the two gases to fully collide, penetrate, and fuse within a limited space. At the same time, the folding plates 201e distributed on the surface of the promoting plate 104 further enhance the shear force and diffusion effect of the air flow, not only significantly improving the mixing uniformity but also effectively reducing the concentration fluctuations caused by the difference in gas specific gravity, ensuring the high stability of the output mixed gas; In addition, the formation of turbulence also optimizes the gas flow path and shortens the mixing time. The integrated design of the promoting plate 104 and the cavity 103 reduces the gas flow resistance, avoiding the pressure loss caused by local eddies while maintaining the mixing efficiency. This synergistic effect enables this device to accurately control the anesthetic gas concentration within a safe range, providing stable anesthesia maintenance for patients and reducing the intraoperative risks caused by uneven mixing; It also includes an adjusting mechanism 300. The adjusting mechanism 300 includes an annular member 301 arranged in the cavity 103. An offset member 302 is arranged inside the annular member 301. An intermittent member 303 is provided on the rotating member 202. The annular member 301 and the offset member 302 cooperate to adjust the size of the connection between the mixing chamber 106 and the cavity 103; At the same time, this device is provided with an adjusting mechanism 300 at the bottom end of the cavity 103 to control the gas discharge cross-sectional area. When the adjusting mechanism 300 reduces the cross-sectional area, the internal pressure of the cavity 103 rises, the turbulence intensity increases, and the mixing and contact time of oxygen and anesthetic gas is prolonged, which can further improve the mixing uniformity in low-concentration anesthesia scenarios. When the cross-sectional area is enlarged, the output of the mixed gas is accelerated, the residence time in the cavity 103 is reduced, and the risk of excessive accumulation of high-concentration anesthetic is avoided; Working principle: During use, the evaporator 101 converts the liquid anesthetic into a gaseous anesthetic with a controllable concentration. Then, the inlet pipe 102 connected to its outlet end introduces the gas into the cavity 103. The promoting plate 104 guides the gas to form a downward turbulent motion. This multi-directionally disturbed airflow pattern breaks the stratification trend of oxygen and anesthetic gas in the laminar flow state, enabling the two gases to fully collide, penetrate, and blend within a limited space. At the same time, the folding plates 201e distributed on the surface of the promoting plate 104 further enhance the shear force and diffusion effect of the airflow. By setting the adjustment mechanism 300, through continuous cross-sectional area changes, the further blending of oxygen and anesthetic gas is achieved. Meanwhile, by setting the auxiliary component 400, the anesthetic gas and oxygen are forced to experience multiple accelerations, decelerations, and direction mutations in the spiral traveling path, thereby significantly extending the interaction time of the two gas molecules within a limited space. When the mixed gas flows through, the arc-shaped surface not only generates a controllable turbulent effect but also induces the gas to undergo a reciprocating swirling motion in the three-dimensional space through the vortex cavity 103 formed between the plates, further enhancing the stability of the mixed gas.

[0025] Embodiment 2, based on Embodiment 1, adds the following technical features: The support member 201 includes support plates 201a fixedly connected to both sides of the inner wall of the cavity 103. A support tube 201b is fixedly connected between the two support plates 201a. The support tube 201b is located at the central position of the promoting plate 104. A movable groove 201c is formed by the downward depression at the bottom end of the support plate 201a. Multiple groups of openings 201d are provided on the outer wall of the promoting plate 104, and folding plates 201e are fixedly connected within the openings 201d. The multiple groups of folding plates 201e on the promoting plate 104 disturb the guided gas, thereby breaking the stratification trend of oxygen and anesthetic gas in the laminar flow state. From Figures 2 to 5 it can be seen that the support plate 201a is located at the central position of the promoting plate 104. Since the promoting plate 104 is a spiral guide vane with a continuous spiral curved surface configuration, the promoting plate 104 guides the gas to form a downward turbulent motion. This multi-directionally disturbed airflow pattern breaks the stratification trend of oxygen and anesthetic gas in the laminar flow state, enabling the two gases to fully collide, penetrate, and blend within a limited space. Multiple groups of openings 201d are provided on the outer wall of the promoting plate 104, and folding plates 201e are fixedly connected within the openings 201d. The folding plates 201e further enhance the shear force and diffusion effect of the airflow, not only improving the mixing uniformity but also effectively reducing the concentration fluctuation caused by the gas density difference. The rotating member 202 includes a mounting plate 202a fixedly connected to the inner wall of the movable groove 201c, a motor 202b is detachably mounted on the upper end surface of the mounting plate 202a, a rotating rod 202c is fixedly connected to the output shaft end of the motor 202b, the rotating rod 202c is arranged in the movable groove 201c, a plurality of rotating blocks 202d are fixedly connected to the outer wall of the rotating rod 202c, and a wave groove 202e is arranged on the outer wall of the rotating block 202d, and the spoiler 203 includes a plurality of annular grooves 203a arranged on the outer wall of the support tube 201b, and the annular grooves 203e are arranged on the outer wall of the support tube 201b. The two sides of 03a are inwardly concave to form a through opening 203b, which is connected to the movable groove 201c. Spoilers 203c are movably connected in the through openings 203b on both sides. The cross-sectional area of ​​the spoiler 203c gradually increases from the inside to the outside. A positioning block 203d is fixedly connected to one end of the spoiler 203c. The positioning block 203d is slidably connected in the wave groove 202e. A sliding opening 203e is provided in the spoiler 203c. A blocking ring 203f is provided in the annular groove 203a. The blocking ring 203f passes through the corresponding sliding opening 203e. Depend on Figures 2 to 9 It can be seen that a motor 202b is detachably installed in the movable groove 201c, and the motor 202b is adjusted by an external controller to drive the rotating block 202d on the rotating rod 202c to rotate. A wave groove 202e is provided on the outer wall of the rotating block 202d, and the wave groove 202e is composed of a lowest section, a highest section and an arc section. An annular groove 203a is provided on the outer wall of the support tube 201b, and a through-port 203b is symmetrically provided in the annular groove 203a. The through-port 203b is a conical structure, and its cross-sectional area gradually increases in diameter from the inside to the outside. A spoiler 203c is movably connected in the through-port 203b, and the spoiler 203c can be stably tilted up and down in the through-port 203b. The positioning block 203d on the spoiler 203c is slidably connected in the wave groove 202e, and the spoiler 203c is limited by a blocking ring 203f, and the blocking ring 203f is made of soft rubber. The positioning block 203d has a T-shaped structure inside the wave groove 202e, ensuring that the positioning block 203d will not be separated from the wave groove 202e, thereby ensuring the stability of the spoiler 203c; When the positioning block 203d moves to the lowest section of the wave groove 202e, its spoiler 203c tilts upward, and when the positioning block 203d moves to the highest section of the wave groove 202e, its spoiler 203c moves downward, so that the rotating block 202d is driven to rotate by the rotating rod 202c, thereby driving the spoiler 203c to tilt up and down. Therefore, when the promotion plate 104 guides the gas to form a downward turbulent movement, the spoiler 203c breaks the stratification trend of oxygen and anesthetic gas in the laminar state, so that the two gases fully collide, penetrate and merge in a limited space, and at the same time, the folding plates 201e distributed on the surface of the promotion plate 104 further enhance the shear force and diffusion effect of the airflow; Working principle: During use, the evaporator 101 converts the liquid anesthetic into a gaseous anesthetic with a controllable concentration. Then, the intake pipe 102 connected to its outlet end guides the gas into the cavity 103. The promotion plate 104 guides the gas to form a downward turbulent motion. This multi-directionally disturbed airflow pattern breaks the stratification trend of oxygen and anesthetic gas in the laminar flow state, enabling the two gases to fully collide, penetrate, and blend within a limited space. At the same time, multiple groups of openings 201d are provided on the outer wall of the promotion plate 104, and a folding plate 201e is fixedly connected within the openings 201d. The folding plate 201e further enhances the shear force and diffusion effect of the airflow, not only improving the mixing uniformity but also effectively reducing the concentration fluctuations caused by the difference in gas specific gravity. During use, the external controller adjusts the motor 202b, and the motor 202b drives the rotating rod 202c to rotate. At this time, the rotating block 202d on the rotating rod 202c rotates. A wave groove 202e is provided on the outer wall of the rotating block 202d. The wave groove 202e consists of a lowest section, a highest section, and an arc section. A spoiler 203c is movably connected within the through port 203b. The wave groove 202e enables the spoiler 203c to stably tilt up and down within the through port 203b, further breaking the stratification trend of oxygen and anesthetic gas in the laminar flow state and having a better mixing effect.

The adjustment mechanism 300 includes an annular member 301 provided within the cavity 103. An offset member 302 is provided within the annular member 301. An intermittent member 303 is provided on the rotating member 202. The annular member 301 and the offset member 302 cooperate to adjust the size of the connection between the mixing cavity 106 and the cavity 103. The annular member 301 includes an annular strip 301a rotatably connected to the upper end surface of the bottom end of the cavity 103. A plurality of connecting plates 301b are fixedly connected to the inner wall of the annular strip 301a. An annular plate 301c is fixedly connected between the plurality of connecting plates 301b. A sliding hole 301d is provided on the upper end surface of the connecting plate 301b. A circular hole 301e is formed in the middle of the annular plate 301c; From Figures 2 to 9 it can be seen that the upper end surface of the bottom end of the cavity 103 is rotatably connected to the annular strip 301a through a bearing. Therefore, when the annular strip 301a rotates, since six groups of connecting plates 301b are fixedly connected to the inner wall of the annular strip 301a in a circular manner, and an annular plate 301c is fixedly connected between the six groups of connecting plates 301b, as described above, the annular strip 301a drives the annular plate 301c within the connecting plate 301b to rotate; The offset member 302 includes a chute 302a that is circumferentially formed on the upper end surface of the bottom end of the cavity 103.

The adjacent two groups of chutes 302a intersect with each other. A corresponding sliding plate 302b is slidably connected in each chute 302a, and the sliding plate 302b only slides in its corresponding chute 302a. The adjacent sliding plates 302b are attached to each other through the first abutting surface 302c and the second abutting surface 302d. When the annular strip 301a rotates, it drives the annular plate 301c in the connecting plate 301b to rotate. The sliding rod 302e slides in the sliding hole 301d and the chute 302a. Due to the offset of the sliding hole 301d, the sliding plate 302b on the sliding rod 302e moves in the chute 302a, and the adjacent sliding plates 302b are attached to each other through the first abutting surface 302c and the second abutting surface 302d, so as to adjust the size of the connection between the mixing cavity 106 and the cavity 103; The intermittent member 303 includes a circular plate 303a fixedly connected to the inner wall of the movable groove 201c. A sleeve 303b is rotatably connected to the bottom end of the circular plate 303a through a bearing. A hollow hole 303c is formed at the center position of the circular plate 303a. The rotating rod 202c correspondingly penetrates through the hollow hole 303c and the sleeve 303b. A torsion spring 303d is sleeved on the outer wall of the sleeve 303b.

A pull rod 303f is fixedly connected to the bottom end of the connecting plate 303e. The pull rod 303f is fixedly connected to the upper end surface of the annular strip 301a. An abutting block 303g is fixedly connected to the inner wall of the sleeve 303b. An extrusion block 303h is fixedly connected to the outer wall of the rotating rod 202c. The abutting block 303g and the extrusion block 303h cooperate with each other; As can be seen from Figures 6 to 9It can be seen that the circular plate 303a is rotationally connected to the sleeve 303b through a torsion spring 303d. An abutting block 303g is fixedly connected inside the sleeve 303b. The abutting block 303g is made of an elastic and deformable material. An extrusion block 303h is fixedly connected to the outer wall of the rotating rod 202c. The abutting block 303g and the extrusion block 303h cooperate with each other. When the motor 202b drives the rotating rod 202c to rotate, the rotating rod 202c drives the extrusion block 303h to cooperate with the abutting block 303g. When the extrusion block 303h contacts the abutting block 303g, the sleeve 303b is driven to rotate. When the rotation angle of the sleeve 303b reaches 60 degrees, at this time the abutting block 303g deforms, so that the rotating rod 202c no longer drives the sleeve 303b to rotate, and due to the restoring force of the torsion spring 303d, the sleeve 303b is driven to rotate back, thereby adjusting the size of the connection between the mixing chamber 106 and the cavity 103; Working principle: As can be seen from Embodiment 2, when the motor 202b drives the rotating rod 202c to rotate, the rotating rod 202c drives the extrusion block 303h to cooperate with the abutting block 303g. When the extrusion block 303h contacts the abutting block 303g, the sleeve 303b is driven to rotate. When the rotation angle of the sleeve 303b reaches 60 degrees, at this time the abutting block 303g deforms, so that the rotating rod 202c no longer drives the sleeve 303b to rotate, and due to the restoring force of the torsion spring 303d, the sleeve 303b is driven to rotate back. At this time, the annular plate 301c connected to the connecting plate 303e rotates, and the sliding rod 302e slides in the sliding hole 301d and the sliding groove 302a. Due to the offset of the sliding hole 301d, the sliding plate 302b on the sliding rod 302e moves in the sliding groove 302a, and the adjacent sliding plates 302b are attached to each other through the abutting surface one 302c and the abutting surface two 302d, so as to adjust the size of the connection between the mixing chamber 106 and the cavity 103. When the connection between the mixing chamber 106 and the cavity 103 shrinks, the pressure inside the cavity 103 rises, the turbulence intensity increases, and the mixing contact time of oxygen and anesthetic gas is extended, which can further improve the mixing uniformity in the low-concentration anesthesia scenario. When the connection between the mixing chamber 106 and the cavity 103 expands, the output of the mixed gas is accelerated, the residence time in the cavity 103 is reduced, and the risk of excessive accumulation of high-concentration anesthetic is avoided. In this way, through continuous cross-sectional area changes, the further fusion of oxygen and anesthetic gas is achieved.

[0027] Embodiment 4, based on Embodiment 3, adds the following technical features: comprising an auxiliary component 400 arranged in the mixing chamber 106, the auxiliary component 400 comprising an auxiliary part 401 arranged in the mixing chamber 106, the upper end surface of the auxiliary part 401 is provided with a reducer 402, the auxiliary part 401 and the reducer 402 cooperate to mix oxygen and anesthetic gas, the auxiliary part 401 comprises an auxiliary plate 401a fixedly connected to the inside of the mixing chamber 106, the upper end surface of the auxiliary plate 401a is provided with air outlets 401b on both sides, the reducer 402 comprises a vortex plate 402a fixedly connected to the upper end surface of the auxiliary plate 401a, a vortex region 402b is formed in the vortex plate 402a, one end of the rotating rod 202c is arranged at the center of the vortex region 402b, and an arc plate 402c is fixedly connected to the outer wall of the rotating rod 202c in a circumferential manner; Depend on Figures 2 to 6 It can be seen that an auxiliary plate 401a is fixedly connected in the mixing chamber 106, and the mixing chamber 106 is divided into two parts by the auxiliary plate 401a. A vortex plate 402a is fixedly connected to the upper end of the auxiliary plate 401a. The vortex plate 402a forces the anesthetic gas and oxygen to undergo multiple accelerations, decelerations and sudden changes in direction in a spiral path, thereby significantly prolonging the interaction time of the two gas molecules in a limited space. The rotating rod 202c is located in the vortex area 402b and is fixedly connected to an arc plate 402c. The rotating rod 202c and the arc plate 402c rotate, thereby disturbing the anesthetic gas and oxygen. Working principle: It can be seen from Example 3 that when the rotating rod 202c rotates, the rotating rod 202c drives the six groups of arc plates 402c to rotate, thereby disturbing the anesthetic gas and oxygen in the vortex area 402b, forcing the anesthetic gas and oxygen to undergo multiple accelerations, decelerations and sudden changes in direction in the spiral path, thereby significantly prolonging the interaction time of the two gas molecules in a limited space, and when the mixed gas flows through, the arc surface not only produces a controllable turbulent effect, but also can induce the gas to perform reciprocating cyclotron motion in a three-dimensional space through the vortex area 402b formed between the plates, further improving the stability of the mixed gas.
