Description

Technical Field

[0001] This invention relates to the field of anesthesia breathing mask technology, specifically to a ventilation device for clinical use in orthopedic general anesthesia. Background Technology

[0002] Currently, the core ventilation component of orthopedic general anesthesia ventilation equipment used in clinical practice is mainly various types of respiratory masks, which, together with anesthesia ventilators, ventilation tubing, and other components, deliver anesthetic gases and provide respiratory support to the patient. The mainstream structure of a common orthopedic general anesthesia respiratory mask typically includes the mask body, ventilation interface, sealing gasket, and head restraint strap, which generally maintains good airtightness when the patient is lying flat.

[0003] However, when patients are in a side-lying position for orthopedic surgery, the existing breathing mask will tilt and shift to the lower side of the body due to its own weight and the tilt of the head. Some existing devices for preventing the dislodgement of anesthesia masks, including one with publication number CN221513181U, rely solely on the axial clamping force of the head strap for fixation. Lacking active correction and traction structures to address lateral tilting, these devices can cause localized detachment of the inner sealing gasket from the facial skin, especially at prominent facial contours such as the cheekbone and jawline. This can create significant gaps, leading to anesthetic gas leakage, affecting the anesthetic effect, and potentially harming the health of surgical personnel. Furthermore, outside air can easily enter the mask, reducing the oxygen concentration and failing to provide effective ventilation support for the patient. In severe cases, this can lead to hypoxia and threaten the patient's life. Secondly, to address the dislodgement problem, medical personnel must frequently adjust the mask position and the tightness of the straps. This not only increases their workload but can also disrupt the continuity of surgical procedures, especially in delicate orthopedic surgeries where frequent adjustments can affect surgical precision. Summary of the Invention

[0004] To address the aforementioned problems, this invention aims to provide a ventilation device for clinical use in orthopedic general anesthesia. By designing an adsorption enhancement component, suction cup structures are installed on both sides of the breathing mask to adhere to the sides of the face. When the patient lies on their side, the rotating lever in the middle of the breathing mask compresses the adjusting slider, connecting the adjusting chamber with the adjusting airways on both sides. The air pressure inside the adjusting chamber pushes the flexible ropes in the connecting tubes on both sides, pulling the piston rods in the suction cups, creating a negative pressure adsorption effect inside the suction cups. This enhances the connection between the upper side of the breathing mask and the face, offering advantages such as strong airtightness, good safety, and wide applicability.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A ventilation device for clinical use in orthopedic general anesthesia includes a breathing mask with an anesthetic gas interface, a pair of connecting tubes on both sides of the breathing mask, a suction cup at the end of the connecting tubes away from the breathing mask, and an adsorption force enhancement component on the breathing mask to enhance the adsorption effect of the suction cup.

[0006] The adsorption enhancement component includes a swing arm rotatably disposed in the middle of the breathing mask. An adjustment cavity is disposed in the middle of the breathing mask directly below the swing arm. A cavity connector is disposed at both ends of the adjustment cavity. Adjustment slide rods are slidably disposed at both ends of the adjustment cavity. The adjustment slide rods can be pushed by the rotation of the swing arm. Adjustment sliders are also slidably disposed at both ends of the adjustment cavity. The adjustment sliders have an inclined structure inside. When the adjustment slide rods are pushed, they can contact the inclined structure, causing the adjustment sliders to slide away from the cavity connectors.

[0007] Each cavity connector is connected to an adjusting air passage. The end of each adjusting air passage away from the adjusting cavity is connected to a connecting pipe on the same side. A flexible sealing ring is provided inside the cavity connector. Both ends of the adjusting cavity are provided with adjusting slider elastic elements that allow the adjusting slider to engage with the cavity connector. The two ends of the flexible sealing ring are connected to the adjusting air passage and the inside of the adjusting cavity, respectively. When the adjusting slider engages with the cavity connector, it can squeeze the flexible sealing ring to disconnect the connection between the adjusting air passage and the adjusting cavity. When the adjusting slider slides away from the cavity connector, the flexible sealing ring naturally expands, allowing the adjusting air passage to connect with the adjusting cavity.

[0008] An adjusting piston is slidably disposed above the adjusting cavity. The top end of the adjusting piston outside the adjusting cavity is provided with a locking connector that can engage with the bottom end of the swing rod. The bottom end of the adjusting piston inside the adjusting cavity is provided with an adjusting piston elastic element that allows the adjusting piston to slide into the adjusting cavity. When the swing rod rotates, the locking connector at the top of the adjusting piston can disengage from the bottom end of the swing rod. The adjusting piston elastic element causes the adjusting piston to move into the adjusting cavity, compressing the gas inside the adjusting cavity into the adjusting gas path, which is in a connected state, and then delivering it to the connecting pipe.

[0009] A suction cup piston rod is slidably disposed inside the suction cup, and a driving piston is disposed inside the connecting tube. The driving piston can be pushed by gas entering the connecting tube. A driving rod is disposed on one side of the driving piston, and a flexible rope is connected between the driving rod and the suction cup piston rod. A flexible rope stop is disposed inside the connecting tube. When the driving piston is pushed by gas, it can drive the driving rod to move. In conjunction with the flexible rope stop, it pushes one end of the taut flexible rope to move, thereby pulling the suction cup piston rod towards the connecting tube through the flexible rope. This creates a negative pressure suction effect inside the suction cup, increases the suction force of the suction cup to the patient's face, and prevents the breathing mask from falling off.

[0010] The breathing mask is also equipped with a soft cushioning strip at the edge.

[0011] The beneficial effects of this invention are: Firstly, this application designs an adsorption-enhancing component. When a patient is adjusted from a supine to a lateral position during orthopedic surgery, the swing arm rotates to squeeze the adjusting slide bar, which in turn squeezes the adjusting slider out of the cavity connector, thus opening the adjusting airway. At the same time, the adjusting piston is released, causing it to slide into the adjusting cavity and squeeze the gas in the adjusting cavity into the gas delivery line and connecting pipe. The gas pushes the piston, which in turn pulls the suction cup piston rod inward relative to the suction cup, creating a negative pressure suction effect between the suction cup and the patient's face. This enhances the adsorption effect of the suction cup on the patient's face and prevents the breathing mask on the upper side from falling off when the patient is lateral, ensuring the airtightness of the breathing mask against the face. Secondly, by strengthening the adsorption force component to enhance the fit between the breathing mask and the face, it can prevent leakage when delivering anesthetic gas into the breathing mask, prevent surrounding medical staff from inhaling it, and avoid harm to medical staff, thus having the advantage of strong safety. Furthermore, the overall structure of this application is a purely mechanical design, requiring no additional electric drive. It is simple in structure, has a low failure rate, and is easy to maintain, making it more suitable for complex clinical surgical environments and thus expanding the scope of application of this application.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0015] The inventors discovered that existing breathing masks tend to tilt to the side when lying down due to their own weight and the tilt of the head. The fixation method of these masks relies solely on the axial clamping force of the head strap, lacking an active correction and traction structure for tilting. When the mask tilts, it can cause the inner sealing gasket to detach from the facial skin, especially in prominent facial contours such as the cheekbone and jaw angle, easily forming obvious gaps and leading to leakage of anesthetic gas.

[0016] Based on the above findings, this application proposes a ventilation device for clinical use in orthopedic general anesthesia. By designing an adsorption enhancement component, suction cup structures capable of adsorbing onto both sides of the face are set on both sides of the breathing mask. When the patient lies on their side, the adjustment slider is moved by rotating the swing rod in the middle of the breathing mask, so that the adjustment chamber is connected to the adjustment air passages on both sides. The air pressure inside the adjustment chamber pushes the flexible rope in the connecting tubes on both sides to pull the piston rod in the suction cup, forming a negative pressure adsorption effect inside the suction cup, thereby enhancing the connection effect between the upper side of the breathing mask and the face. It has the advantages of strong airtightness, good safety and wide applicability. Example 1

[0017] See Figures 1-6 This application discloses a ventilation device for clinical use in orthopedic general anesthesia, including a breathing mask 1. The overall structure of the breathing mask 1 is similar to that of existing breathing masks, and its size is sufficient to cover the patient's mouth and nose. In this embodiment, elastic strap structures can be provided on both sides of the breathing mask 1 to wear the breathing mask 1 on the patient's face. Meanwhile, a soft cushioning band 4 made of soft material is provided at the edge of the breathing mask 1, so that when the patient wears the breathing mask 1, it provides a cushioning effect at the contact point between the edge of the breathing mask 1 and the patient's face, preventing the breathing mask 1 from injuring the facial skin. An anesthetic gas interface 101 is provided on the front side of the breathing mask 1. When the patient is undergoing orthopedic surgery, the anesthetic gas interface 101 is connected to an external anesthetic gas device to provide the patient with anesthesia.

[0018] In this embodiment, a pair of connecting tubes 102 are symmetrically arranged on both sides of the breathing mask 1, and at positions that do not overlap with the elastic strap structure. The connecting tubes 102 are made of a deformable plastic material with a certain strength, and their overall shape is close to "U". A suction cup 2 is provided at the end of the two connecting tubes 102 away from the breathing mask 1. The suction cup 2 is fixed to the end of the connecting tube 102 by the tube structure on one side. When the patient wears this device, the connecting tube 102 can be bent and adjusted manually so that the suction cup 2 can fit against the patient's face. Example 2

[0019] Based on Embodiment 1, further, an adsorption force strengthening component 3 is provided on the breathing mask 1. The adsorption force strengthening component 3 can strengthen the adsorption effect of the suction cup 2 on the upper side on the patient's face when the patient's body position is adjusted from the supine position to the lateral position during orthopedic surgery due to surgical needs, preventing a gap from being generated between the breathing mask 1 and the patient's face due to the change in body position, and thus preventing the leakage of anesthetic gas.

[0020] Refer to Figure 17 , the adsorption force strengthening component 3 includes a swing rod 301. Refer to Figure 13 , a horizontal swing rod mounting rod 103 is provided near the upper side of the front side of the breathing mask 1. The overall shape of the swing rod 301 is close to the shape of the Chinese character 'gan'. The rotating shaft in the middle thereof is rotatably arranged in the mounting hole on the swing rod mounting rod 103; Refer to Figures 7-12 , when the patient is in the supine position, the swing rod 301 and the swing rod mounting rod 103 are in a state of being close to parallel to each other (or close to overlapping in the vertical direction). When the patient is adjusted to the lateral position, the rotation of one side of the head downward will带动 the overall rotation of the breathing mask 1, causing the shorter end of the rod body of the swing rod 301 to rotate in the same direction as the rotation direction of the patient's body, and causing the longer end of the rod body to rotate synchronously in the opposite direction; In this embodiment, on the anesthetic gas interface 101 of the breathing mask 1 and directly below the swing rod 301, an adjustment cavity 302 is provided. The adjustment cavity 302 is a horizontally placed cylindrical cavity structure. Symmetrically arranged on both end faces thereof are slide rod grooves 318. An adjustment slide rod 304 is slidably arranged in the two slide rod grooves 318. The top end of the adjustment slide rod 304 is provided with an inclined surface structure. Refer to Figure 19 , an adjustment slide rod elastic member 316 is arranged in the slide rod groove 318. The adjustment slide rod elastic member 316 is a spring product. In its normal state, it can generate an upward movement tendency of the adjustment slide rod 304 relative to the slide rod groove 318. When the swing rod 301 rotates, its longer end rotates to fit with the inclined surface structure at the top end of the adjustment slide rod 304, and pushes the adjustment slide rod 304 to slide downward relative to the slide rod groove 318 and compress the adjustment slide rod elastic member 316; In addition, a spring structure is arranged in the slide rod groove 318, which can provide a certain upward elastic force effect for the adjustment slide rod 304 to prevent the swing rod 301 from rotating and accidentally triggering the adjustment slide rod 304 when the patient's head tilts slightly in a certain direction during the operation.

[0021] At both ends of the adjusting cavity 302 and below the bottom of the adjusting slide rod 304, cavity connectors 303 are symmetrically arranged. The cavity connectors 304 are hollow cylindrical structures. Each cavity connector 303 has a notch on its side curved surface. Adjusting sliders 305 that can be inserted into the notches on the side of the cavity connectors 303 are slidably arranged at both ends of the adjusting cavity 302 by means of a guide rail structure. In this embodiment, a vertical plate structure is arranged at both ends of the adjusting cavity 302 and away from the notches of the cavity connectors 303. An adjusting slider elastic element 317 is arranged on the plate structure. The adjusting slider elastic element 317 is a spring product. The end of the adjusting slider that is away from the plate is connected to the adjusting slider 305. In the initial state, the adjusting slider elastic element 317 is in a compressed state, which can keep the adjusting slider 305 inserted into the cavity connector 303 along the guide rail structure. See Figure 20 and Figure 21 A flexible sealing ring 307 is provided inside the cavity connector 303. The flexible sealing ring 307 is made of a soft material with good elasticity (such as rubber or medical silicone). It is a circular structure without caps at both ends. One end is connected to the inner cavity of the regulating cavity 302, and the other end is connected to the regulating air passage 305 inserted into the cavity connector 303. The other end of the regulating air passage 305 is connected to the inner cavity of the connecting tube 102 near the end connected to the breathing mask 1. The flexible sealing ring 307 is aligned with the notch on the cavity connector 304 near the middle. When the regulating slider 305 is inserted into the cavity structure 303, it can squeeze the flexible sealing ring 307, causing the inner wall of the flexible sealing ring 307 to fit due to the squeezing action, thereby disconnecting the connection between the regulating air passage 305 and the regulating cavity 302. An inclined structure is provided inside the adjusting slider 305, and the width of the inclined structure is adapted to the width of the bottom end of the adjusting slider 304. When the adjusting slider 304 is not pressed down by the swing rod 301, its bottom end is located at the highest point of the inclined structure of the adjusting slider 305. When one side of the adjusting slider 304 is rotated and pressed down by the swing rod 301, the adjusting slider 305 can be squeezed along the guide rail structure to slide away from the cavity joint 303 through the cooperation between the bottom end of the adjusting slider 304 and the inclined structure inside the adjusting slider 305. When the adjusting slider 305 moves away from the cavity joint 303, it will squeeze the adjusting slider elastic element 317. At this time, the flexible sealing ring 307 naturally expands under the elastic force of its own material, so that the regulating air passage 305 and the regulating cavity 302 are restored to the communication state.

[0022] A vertical cylindrical slide groove structure is provided directly above the adjusting cavity 302, and an adjusting piston 308 is disposed within this slide groove structure. (See reference...) Figure 18The top of the adjusting piston 308 passes through the sliding groove structure at the top of the adjusting cavity 302 and is provided with a snap-fit ​​connector 309 with an inverted "L" shape in cross-section. At the same time, a snap-fit ​​structure that matches the shape of the snap-fit ​​connector 309 (i.e., the cross-section shape is a mirror "L") is provided directly below the rotatable connection between the rocker arm 301 and the rocker arm mounting rod 103. When the patient is in a supine position and the swing arm 301 is parallel to the swing arm mounting rod 103, the top of the adjusting piston 308 can be engaged through the snap-fit ​​connector 309. At the same time, an adjusting piston elastic element 310 is provided inside the adjusting cavity 302 and below the adjusting piston 308. The adjusting piston elastic element 310 is an elastic rope product. In this embodiment, when the top of the adjusting piston 308 is engaged, it can keep the adjusting piston 308 in a limited state. At this time, the adjusting piston elastic element 310 is in a stretched state. When the patient turns to the side in a certain direction, when the swing arm 301 rotates, its bottom can release the snap-fit ​​effect on the top of the adjusting piston 308 snap-fit ​​connector 309, so that the adjusting piston 308 moves into the adjusting cavity 302. At this time, one of the adjusting air passages 305 is connected to the adjusting cavity 302. The adjusting piston 308 can squeeze the gas in the adjusting cavity 302 into the adjusting air passage 305, and then deliver the gas to the connecting block 102. Example 3

[0023] See Figure 14 , Figure 15 and Figure 16 Based on Embodiment 2, in this embodiment, a suction cup piston rod 311 is slidably disposed inside the tube structure of the suction cup 2. At the same time, a drive piston 312 is slidably disposed inside the end of the connecting tube 102 near the end connected to the regulating air passage 305. A drive rod 313 is disposed on the drive piston 312, and a flexible rope 314 is connected to the end of the drive rod 313 away from the drive piston 312. The flexible rope 314 is an elastic and stable rope, and its other end passes through the tube structure of the suction cup 2 and is connected to the suction cup piston rod 311. A flexible rope stop bar 315 is fixed inside the connecting tube 102 near the drive rod 313. The flexible rope 314 forms a change of direction at the flexible rope stop bar 315. An air vent 104 is provided on the side of the connecting tube 102. When gas in the regulating chamber 302 enters the connecting tube 102, it can squeeze the driving piston 312 to move away from the breathing mask 1. When the driving piston 312 moves, it can discharge the gas in the connecting tube 102 through the air vent 104. At the same time, the driving rod 313, in conjunction with the flexible rope stop rod 315, changes the direction of the flexible rope, tightens and stretches the flexible rope 314, and pulls the suction cup piston rod 311 towards the inside of the connecting tube 102. At this time, since the suction cup 2 is in contact with the patient's face, the movement of the suction cup piston rod 311 can generate a negative pressure suction effect in the inner cavity of the suction cup 2, thereby strengthening the adsorption effect between the suction cup 2 and the patient's face and preventing gaps from forming between the breathing mask 1 and the patient's face.

[0024] The above-mentioned method of using a ventilation device for clinical general anesthesia in orthopedics includes the following steps: S1. Cover the patient's mouth and nose with the breathing mask 1, adjust the connecting tube 102 on the side so that the suction cup 2 is attached to and adsorbed to the patient's face, and wear the device on the patient's face with the elastic strap structure, and connect the device that provides anesthetic gas to the anesthetic gas interface 101. S2. During orthopedic surgery, the patient's body is adjusted from a supine position to a lateral position. The head is rotated to rotate the lever 301 on the breathing mask 1, and the adjustment slide 304 on one side is pushed down, so that the adjustment air passage 306 located above the patient after the patient is in a lateral position is connected to the adjustment cavity 302. At the same time, the adjustment piston 308 is released to squeeze the gas in the adjustment cavity 302 into the adjustment air passage 306. S3. Gas enters the connecting tube 102 through the regulating gas passage 306 and pushes the drive piston 312 to stretch the flexible rope 314, which in turn pulls the suction cup piston rod 311 located above into the connecting tube 102, so that a negative pressure suction effect is formed in the suction cup 2 located above, which strengthens the suction effect of the suction cup 2 on the patient's face and ensures the airtightness between the breathing mask 1 and the face.
