Description

Technical Field

[0001] The invention relates to an atomizing breathing drug delivery device. Background Art

[0002] Compressed air nebulizer is a medical device that uses the principle of gas jet to spray liquid medicine at high speed to form tiny droplets suspended in the gas, forming an aerosol and entering the respiratory tract for drug inhalation therapy. The atomized inhalation therapy formed by the compressed air nebulizer directly acts on the lesion site. Compared with the oral method, it has the advantages of small dosage, quick effect, few side effects and convenient use, and has significant efficacy. The local drug concentration in the respiratory tract is high, which can avoid or reduce the use of systemic hormones. The patient only needs to cooperate passively to ensure the effectiveness of the drug, which has become a more ideal route of drug administration today.

[0003] The existing compressed air nebulizer includes a compressor, a nebulizer cup, a catheter and a mask. The two ends of the catheter are respectively connected to the input end of the nebulizer cup and the output end of the compressor, and the mask is connected to the output end of the nebulizer cup. At the output end of the compressor is usually an air jet. One end of a catheter is inserted into the air jet by squeezing. The compressor compresses the filtered clean air into a strong airflow that is ejected from the air jet and impacts the liquid medicine in the nebulizer cup through the catheter, so that the liquid medicine is vaporized and then output through the mask for the patient to inhale into the lungs and other parts of the body through the mouth and nose, so as to achieve the purpose of treatment. However, the air jet on the compressor can usually only be connected to one catheter. The number of compressors that can be used in hospitals or clinics is limited and cannot meet the needs of patients, and increasing the number of compressors will increase costs. Summary of the invention

[0004] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide an atomizing breathing drug delivery device to solve the problem of limited use of atomizers for medication in hospitals or clinics.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide an atomizing breathing drug delivery device and specifically include a gas compression mechanism with a jet port and a drug delivery mechanism for installing a drug solution and delivering the drug solution to a patient's mouth and nose, the drug delivery mechanism is connected to the gas compression mechanism, and after the gas compression mechanism provides compressed air to the drug delivery mechanism, the drug solution injected into the drug delivery mechanism is impacted by a high-speed airflow jet to form droplets of different sizes, the lighter droplets are output into the patient's mouth and nose, and the larger droplets flow back to continue to be blown away until all the drug solution is atomized into lighter droplets; a connector with an inner cavity connected to the jet port is connected to the jet port of the gas compression mechanism, and the connector has a plurality of output parts connected to the inner cavity of the connector that are detachably connected to the drug delivery mechanism, and the plurality of output parts enable the jet port of the gas compression mechanism to be connected to multiple drug delivery mechanisms at the same time, so that multiple patients can be provided with atomization drug delivery treatment at the same time without increasing power output and equipment costs, thereby providing convenience for hospitals, clinics and patients.

[0006] The connector includes a main body with a hollow interior, a connecting part connected to the main body input end and connected to the main body inner cavity, and a plurality of opening and closing parts adapted to each output part and respectively opening and closing each output part by rotating. Each output part is arranged on the main body and respectively connected to the main body inner cavity. The main body has a rectangular input port at the input end to open the output part as needed. When any output part is not in use, the output part can be closed to avoid gas leakage and dust in the external air from entering the main body. The connector also includes an adjusting part arranged in the main body, which is connected to each of the opening and closing parts. When each of the opening and closing parts is rotated to open and close the output part, the adjusting part is driven to adjust the flow rate at the input port. When the user needs to use or close the output part and uses the opening and closing part, the opening and closing part can simultaneously drive the operation of the adjusting part to adjust the gas flow rate at the input port, thereby ensuring that a suitable amount of gas is output when multiple drug delivery mechanisms are used at the same time.

[0007] One end of the connecting part is connected to the input end of the main body, and the other end is detachably connected to the air jet port, so that the connector can be removed for repair and maintenance.

[0008] An input pipe connecting the inner and outer cavities of the main body is formed at the input end of the main body and extends toward a side away from the main body, and the input port is located on the input pipe; the connecting portion includes a connecting pipe with one end rotatably sleeved on the input end and with two ends connected, and the end of the connecting pipe away from the input pipe is threadedly connected to the air jet port, so that when installing the connector, the threaded connection is not only simple to operate but also firmly connected.

[0009] The main body is arranged horizontally along a transverse direction, and the input port is located in the middle of the main body; the adjustment part includes a plurality of shielding sheets adapted to the opening and closing part and respectively slidably connected to the inner wall of the main body, a pull rope whose one end adapted to the shielding sheets is respectively connected to one end of each shielding sheet, a guide rope group vertically arranged in the main body, and a tension spring whose one end adapted to the shielding sheets is respectively connected to the other end of each shielding sheet, each of the shielding sheets is arranged to slide along the transverse direction, and each of the shielding sheets and the input port are located on the same side of the main body, and each of the shielding sheets is arranged to slide along the transverse direction. The pull ropes are sequentially distributed in different directions and one end away from the pull rope extends into the input port in the lateral direction to block part of the input port, thereby limiting the flow at the input port. The other end of each pull rope is respectively wound around the guide rope group and then continues to extend and is connected to the opening and closing part. The other end of each tension spring extends toward the side away from the shielding piece and is connected to the main body, so that the opening and closing part can drive the shielding piece to slide through the pull rope at the same time when in use, and cooperate with the tension spring to move the shielding piece toward and away from the input port to block or open the input port, thereby achieving the purpose of regulating the flow at the input port.

[0010] The guide rope group includes a first rotating shaft and a second rotating shaft distributed at an interval of the first rotating shaft, and guide ring grooves adapted to each pull rope are formed on the first rotating shaft and the second rotating shaft. The end of the pull rope away from the shielding plate successively passes around the guide ring grooves on the first rotating shaft and the second rotating shaft and is connected to the corresponding opening and closing part to make the pull rope present a "Z" shape. This ensures that the pull rope is in a straight state under the action of each tension spring, and prevents the pull ropes from being entangled and knotted to affect the pulling of the shielding plate.

[0011] A plurality of output ports matched with the output part are formed on the main body, and each of the output parts is respectively arranged at each output port; the opening and closing part includes a main shaft arranged to rotate in the vertical direction at the center line of the corresponding output part, and a blocking piece fixedly connected to the main shaft in the middle and located at the output port for blocking the output port, one end of the main shaft extends outside the main body, and a knob is provided on the end of the main shaft extending outside the main body, so as to open and close the output port by rotating the knob to drive the main shaft to rotate, and a traction rod with one end extending toward the side away from the main shaft is horizontally provided on the side of the main shaft away from the output port, and the end of the pull rope away from the shielding plate is connected to the traction rod, so that after the main shaft is rotated, the traction rod pulls the pull rope to move a moving distance to make the shielding plate move a certain distance relative to the input port.

[0012] The output part includes an output tube with an internal hollow arrangement connected to the main body at one end and connected to the corresponding output port, and a connecting port is provided on the other end of the output tube so that the gas in the gas compression mechanism can be output through the connecting port on the output tube; the drug delivery mechanism includes a conduit with one end detachably connected to the connecting port, an atomizer cup with an input end connected to the other end of the conduit, and a mask detachably connected to the output end of the atomizer cup, the top of the atomizer cup is provided with a drug injection port, and the conduit of the drug delivery mechanism is connected to the connecting port to inject gas into the atomizer cup.

[0013] A connecting joint is provided on the end of the conduit away from the atomizer cup, and the connecting joint includes a connector fixedly connected to the conduit and a threaded tube fixedly connected to the end of the connector away from the conduit. The threaded tube, the connector and the conduit are coaxially arranged and connected in sequence. The connecting port and the threaded tube are threadedly connected, and one end of the conduit is connected to the output pipe by threaded connection. This connection method is not only firm, but also convenient and simple to operate.

[0014] The inner wall of the connection port is convexly extended inwardly and has a diameter smaller than the inner diameter of the output tube. The output part also includes a sealing plug located in the output tube and hinged to the inner wall of the output tube at one side. A first torsion spring is arranged between the sealing plug and the inner wall of the output tube. The first torsion spring is in a compressed state without the application of external force and causes the sealing plug to be squeezed to the connection port to block the connection port. In this way, the connection port can be blocked when the output tube is not connected to the catheter to prevent impurities, bacteria, etc. in the air from entering the inner cavity of the main body. At the same time, when the gas compression mechanism is running, the flow direction of the gas causes the sealing plug to further seal the connection port to ensure air tightness, and also to ensure the main body The gas inside the main body will not escape from the connecting port and release the pressure; an extrusion tube coaxially arranged with the threaded tube is formed on the end of the threaded tube away from the conduit and extending along the axial direction of the threaded tube, the diameter of the extrusion tube is smaller than the diameter of the connecting port and both ends are connected to connect the conduit and the output tube, and the extrusion tube will push open the sealing plug at the connecting port when the connecting head is screwed to the connecting port, so that the compressed gas in the main body can enter the conduit, and when the extrusion tube pushes open the sealing plug, the threaded cooperation between the connecting head and the connecting port prevents the gas in the main body from leaking; a reset part is provided on the output tube, which is used to drive the main shaft to automatically reset after the connecting head is taken out.

[0015] The atomizing breathing drug delivery device of the present invention has at least the following beneficial effects: by providing a connector, a plurality of drug delivery mechanisms can be connected to the compressor at the same time, which reduces the burden on hospitals or clinics, and greatly shortens the waiting time for patients; with the cooperation of the connector and the output part, the output part can be closed when not in use to prevent gas leakage from the gas compression mechanism when in use and affect the air pressure, and at the same time, when the output part is not in use, unfiltered air is prevented from entering the connector and causing bacteria and the like to enter the drug delivery mechanism and affect the health of the patient; and the connector can also complete the gas flow adjustment at the input end of the connector while opening and closing the output part, so that the number of output parts used corresponds to the flow.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Reference Figures 1 to 7 As shown, an atomizing breathing drug delivery device of the present invention comprises a gas compression mechanism 1 with an air jet 11, a drug delivery mechanism 2 for delivering drug solution and delivering drug solution through the patient's mouth and nose, and a connector 3 for connecting to the air jet 11 on the gas compression mechanism 1. The gas compression mechanism 1 is used to absorb, filter and compress external air and then output it from the air jet 11. The inner cavity of the connector 3 is connected to the air jet 11 when connected to the air jet 11, so that the compressed air enters the connector 3 and is output to the drug delivery mechanism 2. The drug delivery mechanism 2 is used to deliver drug solution. After the drug solution is injected into the drug delivery mechanism 2, the high-pressure gas delivered through the connector 3 disperses the liquid drug solution after entering the drug delivery mechanism 2 to form droplets of different sizes. The smaller droplets float to the output end of the drug delivery mechanism 2 under the blowing of the continuously delivered gas, so that the drug solution in the form of water mist can be delivered to the patient's mouth and nose, so that the drug solution can more easily enter the patient's oral cavity and nasal cavity and further enter the intestines, stomach, lungs and other internal organs, so that the drug treatment is faster and more easily absorbed.

[0028] The gas compression mechanism 1 includes a compressor, which has a vent 12 for facilitating air intake and heat dissipation. A filter structure for filtering air is provided inside the compressor, and filtering is usually achieved through filter cotton, etc., and an air pump is provided inside it. A switch and an adjustment knob 343 for the power of the air pump are provided on the compressor casing, and the air jet 11 is connected to the ventilation pump. The compressor is a common air compressor for atomizers on the market. The air compressor is an existing common structure and will not be described in detail here.

[0029] The drug delivery mechanism 2 includes a catheter 21 having an input end and an output end, and the input end is detachably connected to the connector 3, an atomizer cup 22 having an input end and an output end, and the input end is connected to the output end of the catheter 21, and a mask 23 detachably connected to the output end of the atomizer cup 22. The catheter 21 facilitates the connection and communication between the drug delivery mechanism 2 and the connector 3. The top of the atomizer cup 22 has a drug injection port. After the medical staff injects the drug solution into the atomizer cup 22 through the drug injection port, the operation of the gas compression mechanism 1 transports the compressed high-pressure gas toward the atomizer cup 22 through the connector 3. The high-pressure gas passes through the catheter 21 and the input end of the atomizer cup 22 in turn until it enters the interior of the atomizer cup 22. The structure inside the atomizer cup 22 causes the drug solution to be impacted into the drug solution by the high-pressure gas, and is output into the mask 23 through the output end of the atomizer cup 22. After the patient wears the mask 23 on the mouth and nose, the drug solution enters the patient's mouth and nose along the mask 23 between the patient's breath, thereby achieving the purpose of drug delivery.

[0030] In this embodiment, after one end of the conduit 21 is connected to the input end of the atomizer cup 22 , a connecting joint 24 is disposed on the other end of the conduit 21 , and the connecting joint 24 is detachably connected to the connector 3 .

[0031] Reference Figures 3 to 6As shown, the connector 3 includes a main body 31 with an input end and an output end, a connecting portion 32 connected to the input end of the main body 31 and connected to the inner cavity of the main body 31, a plurality of output portions 33 arranged at the output end of the main body 31, a plurality of opening and closing portions 34 adapted to each output portion 33 for respectively opening and closing each output portion 33 by rotation, and an adjusting portion 35 arranged in the main body 31. The main body 31 is connected to the jet port 11 through the connecting portion 32 at the input end so that the compressed gas output at the jet port 11 enters the inner cavity of the main body 31. The output portion 33 is detachably connected to the connecting joint 24 of the catheter 21, and the output portion 33 is connected to the inner cavity of the main body 31. When many patients need to undergo atomization drug administration treatment, the atomization cup 22 can be used by connecting one end of the catheter 21 to the idle output portion 33 through the connecting joint 24, and the arrangement of the plurality of output portions 33 is A root catheter 21 can be connected to the main body 31, so that more patients can be provided with aerosol drug administration treatment on the basis of one compressor to alleviate the tight use of the equipment. The regulating part 35 cooperates with the opening and closing part 34. While the output part 33 is opened and closed by rotating the opening and closing part 34, the regulating part 35 is driven by the rotation of the opening and closing part 34 to adjust the flow at the input end of the main body 31. Every time an output part 33 is opened, the regulating part 35 increases the gas flow at the input end of the main body 31. Every time an output part 33 is closed, the regulating part 35 reduces the gas flow at the input end of the main body 31. In this way, when the output part 33 is used for aerosol drug administration treatment, the flow at the input end can be autonomously adjusted according to the number of output parts 33 used to make it adapt to the number of output parts 33 used. The flow at the input end of the main body 31 is proportional to the number of output parts 33 used.

[0032] The main body 31 is a rectangular parallelepiped structure and is arranged horizontally along a transverse direction in its length direction. An input port 311 is formed on a side surface of the main body 31 facing the gas compression mechanism 1. The input port 311 is the input end of the main body 31. An input pipe 312 with two ends passing through and connected to the input port 311 is extended from the main body 31 and located at the input end toward the side of the gas compression mechanism 1 (i.e., toward the side away from the main body 31). The input pipe 312 connects the inner and outer cavities of the main body 31, and the connecting portion 32 is connected to the end of the input pipe 312 away from the main body 31.

[0033] In this embodiment, one end of the connection part 32 is connected to the input end of the main body 31, and the other end of the connection part 32 is detachably connected to the jet port 11. The connection part 32 includes a connection pipe 321 with one end connected to the input end of the main body 31 and two ends connected, so that the connection pipe 321 is connected to the input port 311; the end of the connection pipe 321 away from the input pipe 312 is detachably connected to the jet port 11, and the connection pipe 321 can be directly mounted on the jet port 11. Preferably, the end of the connection pipe 321 away from the input pipe 312 is threadedly connected to the jet port 11, which is not only simple in connection method, but also firmly connected, and will not fall off easily even under the impact of high-pressure gas at the jet port 11 of the gas compression mechanism 1, and the threaded connection method can also ensure the airtightness of the connection pipe 321 after being connected to the jet port 11. Specifically, an internal thread is formed on the inner wall of the end of the connecting pipe 321 away from the input pipe 312, and the jet port 11 is adapted to the connecting pipe 321. The jet port 11 extends along its axial direction toward the side away from the gas compression mechanism 1 and presents a circular tubular structure, and an external thread adapted to the internal thread of the connecting pipe 321 is formed on the outer wall of the jet port 11; or an external thread is provided on the outer wall of the connecting pipe 321, and a thread is provided on the inner wall of the jet port 11 to realize a threaded connection between the connecting pipe 321 and the jet port 11.

[0034] Preferably, one end of the connecting tube 321 is connected to the main body 31 and is rotatably connected to the input tube 312. When the connector 3 is installed on the air jet 11 or the connector 3 is removed from the air jet 11, the main body 31 will rotate accordingly. However, due to the shape of the main body 31 itself, when the connecting tube 321 is manually rotated, the rotating main body 31 will block the arm of the disassembler and cause trouble to him. However, rotating the connecting tube 321 connected to the input tube 312 can avoid this problem and reduce the loading and unloading burden of the connector 3. Specifically, a cylindrical mounting groove is formed on one end of the connecting tube 321 facing the input tube 312, and a cylindrical screw groove 322 is formed on one end of the connecting tube 321 away from the input tube 312. A first limiting convex portion 323 is formed between the mounting groove and the screw groove 322 by the inner wall of the connecting tube 321 along the radial direction of the connecting tube 321 toward the circular side. A first through hole 324 is formed on the first limiting convex portion 323 to connect the screw groove 322 and the mounting groove. The diameter of the first through hole 324 is smaller than the diameter of the screw groove 322. The diameters of the groove 322 and the mounting groove are arranged, the screw groove 322 is screwed together with the air jet 11, and an annular groove is formed on the inner wall of the mounting groove along the inner wall of the mounting groove, and the end of the input pipe 312 away from the main body 31 is movably inserted in the mounting groove, and an annular groove is formed on the outer wall of the input pipe 312 at a position corresponding to the annular groove, the annular groove and the annular groove are buckled with each other, and a plurality of balls are arranged in the annular groove and the annular groove, so that the input pipe 312 can rotate freely relative to the connecting pipe 321.

[0035] There are at least two output parts 33, each of which is arranged on the main body 31 and connected to the inner cavity of the main body 31, and each of the output parts 33 is evenly spaced. A plurality of output ports corresponding to the number of the output parts 33 are formed on the side surface of the main body 31 away from the gas compression mechanism 1 and opposite to the input port 311, and each of the output parts 33 is arranged at each output port so that each of the output parts 33 is connected to the output port. The output part 33 includes an output pipe 331 with one end connected to the main body 31 and connected to the corresponding output port, and a sealing plug 332 located in the output pipe 331 and hinged to the inner wall of the output pipe 331 at one end. The other end of the output pipe 331 has a connecting port 333, and the connecting joint 24 of the conduit 21 is connected to the connecting port 333. The sealing plug 332 is used to block the output pipe 331.

[0036] The output tube 331 is a circular tube structure, one end of the output tube 331 is fixedly connected to the outer wall of the main body 31, and each output tube 331 is coaxially distributed with each output port so that the inner cavity of the output tube 331 is connected with the output port. A second position-limiting convex portion in the shape of a circular ring is provided in a circle along the radial direction of the output tube 331 on the inner wall of the end of the output tube 331 away from the main body 31, and the inner side of the second position-limiting convex portion is penetrated along the axial direction of the output tube 331 to form the connection port 333, the diameter of the connection port 333 is smaller than the inner diameter of the output tube 331, and the sealing plug 332 is hinged on the side surface of the second position-limiting convex portion facing the main body 31. A first torsion spring is arranged on the sealing plug 332 or the second limiting protrusion in a direction perpendicular to the output pipe 331, and the two torsion arms of the first torsion spring are respectively connected to the sealing plug 332 and the second limiting protrusion so that the first torsion spring is located between the second limiting protrusion and the sealing plug 332, and the sealing plug 332 is located on the side of the first torsion spring facing the connecting port 333 relative to the first torsion spring. The first torsion spring is in a compressed state when no external force is applied, and the two torsion arms of the first torsion spring squeeze the sealing plug 332 and the second limiting protrusion in opposite directions, so that the sealing plug 332 is always squeezed toward the side of the connecting port 333 until it contacts the second limiting protrusion and is blocked at the connecting port 333. The side of the sealing plug 332 facing the connecting port 333 is hemispherical in structure and the central axis is coaxially distributed with the central axis of the connecting port 333. The sealing plug 332 is convexly arranged facing the center of the connecting port 333 along the axial direction of the output pipe 331 toward the side away from the main body 31 so that the sealing plug 332 can quickly enter the connecting port 333 to block the connecting port 333, thereby preventing external air from entering the output pipe 331 through the connecting port 333. There is a large amount of dust and bacteria in the air. If the air enters the output pipe 331, when the connecting joint 24 is connected to the output pipe 331, a large amount of dust and bacteria will enter the nebulizer cup 22 driven by the airflow to attach to the medicine liquid, and even enter the patient's body through the patient's mouth and nose through the nebulized medicine liquid, thereby affecting the patient's health. In this embodiment, the sealing plug 332 can block the connecting port 333 before the connecting joint 24 is connected to the output pipe 331 to prevent air from entering the inner cavity of the output pipe 331, so as to ensure the hygiene of the connector 3 and the safe use of the equipment. At the same time, when the opening and closing part 34 is opened and the connecting joint 24 has not yet been connected to the connecting port 333, the sealing plug 332 can further block the connecting port 333 under the action of the airflow to prevent the gas from being output from the output pipe 331 after the opening of the opening and closing part 34 to the outside of the main body 31 and causing gas leakage, which not only avoids contamination by bacteria, etc., but also ensures that the air pressure in the main body 31 is relatively stable and does not leak.In order to facilitate the connection of the catheter 21 to the output tube 331, the connecting joint 24 includes a connector 241 fixedly connected to the catheter 21, a threaded tube 242 fixedly connected to the end of the connector 241 away from the catheter 21, and an extruded tube 243 arranged on the end of the threaded tube 242 away from the catheter 21. The threaded tube 242, the connector 241, the extruded tube 243 and the catheter 21 are coaxially arranged and connected in sequence. The connecting port 333 is threadedly connected to the threaded tube 242, and the diameter of the extruded tube 243 is smaller than the diameter of the connecting port 333 so that the extruded tube 243 can move through the connecting port 333. The threaded tube 242 has an interface 333, and both ends of the squeeze tube 243 are arranged through. When the threaded tube 242 is connected to the connection port 333, the squeeze tube 243 will squeeze the sealing plug 332 toward the output tube 331 as the threaded tube 242 moves as a whole, until the threaded tube 242 is connected to the connection port 333, the squeeze tube 243 opens the sealing plug 332, and the gas enters the conduit 21 through the squeeze tube 243 to prevent the sealing plug 332 from blocking the flow of gas. Preferably, the sealing plug 332 is made of elastic materials such as rubber or silicone to better block the connection port 333. Preferably, the length of the squeeze tube 243 is less than the length of the connection port 333, so that before the threaded tube 242 is screwed to the connection port 333, the squeeze tube 243 will not open the sealing plug 332, thereby preventing air from polluting the output tube 331. Specifically, an external thread is provided on the outer wall of the threaded tube 242, and a matching internal thread is provided on the inner wall of the connecting port 333. The connecting head 241 provides a support point for the operator during use, so that the threaded tube 242 can be installed or removed from the connecting port 333 by rotation. It should be noted that the conduit 21 can be sleeved on the output pipe 331 in the same way as in the prior art. However, this method relies on the elastic characteristics of the conduit 21 itself to achieve connection through stretching deformation. This connection method has disadvantages. The gas output by the gas compression mechanism 1 is high-pressure gas with a relatively high air pressure. After the end of the conduit 21 is sleeved on the output pipe 331, if the sleeve distance is short, it is easy to cause the conduit 21 to fall off under the impact of the air pressure. In order to ensure the firmness of the connection, it is necessary to make the conduit 21 as long as possible on the output pipe 331, which will increase the difficulty of installation and will also cause difficulty in disassembly. The threaded tube 242 in this embodiment is threadedly connected to the connecting port 333, which is not only convenient for installation and disassembly, but also has a firm connection and high airtightness, which solves the defects of the prior art.

[0037] The opening and closing part 34 includes a main shaft 341 that is rotatably arranged at the center line of the corresponding output part 33 in the vertical direction, and a blocking piece 342 that is fixedly connected to the main shaft 341 in the middle and located at the output port for blocking the output port. The top end of the main shaft 341 extends to the outside of the main body 31 in the vertical direction, and a knob 343 is arranged on one end of the main shaft 341 that extends to the outside of the main body 31, so that the main shaft 341 can be rotated by the knob 343. The structures of the main shaft 341, the blocking piece 342 and the knob 343 are basically the same as those of the cylindrical butterfly valve, and the detailed structure refers to the structure of the butterfly valve, which will not be repeated here. When in use, the output port is blocked or opened by turning the knob 343. When an output tube 331 is needed for a patient to undergo aerosol drug administration, the output port is opened. Targeted opening can prevent the inner cavity of the unused output tube 331 from increasing friction with the airflow and slowing down the airflow. After the unused output tube 331 is closed by the opening and closing portion 34, the airflow cannot enter the output tube 331, and the flow direction of the gas in the main body 31 is relatively stable, while also preventing the occurrence of airflow leakage.

[0038] Reference Figure 2 As shown, preferably, a limit block 313 is provided on the top surface of the main body 31 and on both sides of each knob 343, that is, each knob 343 corresponds to two limit blocks 313, and the limit blocks 313 are respectively arranged on both sides of the main shaft 341. The knob 343 includes a rotating plate perpendicular to the main shaft 341, and the two ends of the rotating plate extend back to the side away from the main shaft 341, and the rotating plate is located between the two corresponding limit blocks 313, wherein one limit block 313 abuts against one end of the rotating plate, and the other limit block 313 abuts against the other end of the rotating plate, thereby limiting the rotation angle and rotation direction of the rotating plate, so that the two ends of the rotating plate swing between the two limit blocks 313 after rotation, and when rotating, the two ends of the rotating plate are moved toward the side away from the two limit blocks 313 to enable rotation, and the rotation is completed when the two ends of the rotating plate abut against the two limit blocks 313 respectively, so that the blocking piece 342 blocks or opens the output port. Preferably, a traction rod 344 is arranged in the horizontal direction on each main shaft 341, one end of the traction rod 344 is fixedly connected to the main shaft 341, and the other end of the traction rod 344 extends toward the side away from the main shaft 341. When the blocking piece 342 is in a state of blocking the output port, the traction rod 344 is located directly below one of the limit blocks 313 of the opening and closing part 34. When the blocking piece 342 is in a state of opening the output port, the traction rod 344 is located directly below the other limit block 313 of the opening and closing part 34, so that the two limit blocks 313 can not only limit the direction of the main shaft 341, but also limit the rotation direction of the traction rod 344, so that the end of the traction rod 344 away from the main shaft 341 has a certain swinging path after the main shaft 341 rotates.

[0039] Preferably, the input port 311 is rectangular, and the adjusting portion 35 is connected to each traction rod 344. Specifically, the adjusting portion 35 includes a plurality of shielding pieces 351 corresponding to the number of the opening and closing portions 34, a pull rope 352 corresponding to the number of the shielding pieces 351 and connected to one end of each shielding piece 351, a guide rope group vertically arranged in the main body 31, and a tension spring 354 corresponding to the number of the shielding pieces 351 and connected to the other end of each shielding piece 351, each shielding piece 351 is slidably connected to the inner wall of the main body 31 in the transverse direction, and the shielding piece 351 and the input port 311 are located on the same side of the main body 31.

[0040] There are two distribution modes for the setting of the shielding piece 351 and the setting of the input port 311. In the first embodiment, at one end of the input port 311 close to the main body 31, each shielding piece 351 and the output tube 331 are located on the same side of the input port 311, and each shielding piece 351 is sequentially distributed along the vertical direction and arranged adjacent to each other. The end of each shielding piece 351 away from the pull rope 352 extends into the input port 311 along the transverse direction to block about two-thirds of the input port 311, and can also block the entire input port 311. A guide rail is arranged along the transverse direction at the position corresponding to each shielding piece 351 on the inner wall of the main body 31, and a slide groove that slides with the guide rail is arranged on the shielding piece 351. The end of the guide rail away from the input port 311 extends along the inner wall of the main body 31 toward the side away from the input port 311 so that the length is far greater than the length of the shielding piece 351. The length of the shielding sheet 351 is greater than the length of the input port 311, and a portion of the shielding sheet 351 is always slidably disposed on the guide rail. One end of each pull rope 352 is respectively wound around the guide rope group and then continues to extend and is respectively connected to each traction rod 344. The function of the traction rod 344 is to increase the pulling distance of the pull rope 352 after the main shaft 341 rotates, so that after the main shaft 341 rotates, the pull rope 352 can be pulled by the traction rod 344 to move one end distance, which is also the distance that the shielding sheet 351 moves under the drive of the pull rope 352. In this embodiment, the guide rope assembly includes a first rotating shaft 3531 and a second rotating shaft 3532. The first rotating shaft 3531 and the second rotating shaft 3532 are arranged at intervals. The first rotating shaft 3531 is arranged on a side away from the input port 311 along the length direction of the main body 31, and the second rotating shaft 3532 is arranged on a side close to the input port 311 along the length direction of the main body 31. The second rotating shaft 3532 is closer to the first rotating shaft 3531 in the axial direction horizontally perpendicular to the connecting tube 321. Away from the input port 311, one end of the pull rope 352 away from the shielding plate 351 passes around the first rotating shaft 3531 and then continues to pass around the second rotating shaft 3532, and is finally connected to each traction rod 344 respectively. After being wound around the first rotating shaft 3531 and the second quasi-axis, the pull rope 352 presents a "Z" shape or an "S" shape. The lengths of the pull ropes 352 are different. The lengths of the pull ropes 352 are proportional to the distances of the traction rods 344 from the second rotating shaft 3532, so as to ensure that the pull ropes 352 remain taut under the action of the tension spring 354. One end of the tension spring 354 away from the shielding plate 351 extends along the lateral direction toward the side away from the shielding plate 351 and is connected to the inner wall of the main body 31. The tension spring 354 is in a normal state when the opening and closing part 34 closes the output port. At this time, under the traction of the tension spring 354, the first rotating shaft 3531, the second rotating shaft 3532 and the traction rod 344, each pull rope 352 is in a straight state. The first rotating shaft 3531 and the second rotating shaft 3532 are both used to guide the pull rope 352, and the first rotating shaft 3531 is used to enable the traction rod 344 to pull the shielding plate to move after rotation.When the output port is in a closed state, the end of the shielding piece 351 away from the pull rope 352 is located in the input port 311. At this time, when the opening and closing part 34 is rotated to rotate it from the closed output port state to the open state, the traction rod 344 rotates accordingly and pulls the pull rope 352 so that the pull rope 352 pulls the shielding piece 351 to slide toward the side of the pull rope 352 to gradually move away from the input port 311. In this process, the tension spring 354 is pulled and is in a stretched state. When the output port is fully opened, the end of the shielding piece 351 away from the pull rope 352 no longer blocks the column input port 311. At this time, the corresponding output pipe 331 is connected to the inner cavity of the main body 31. At the same time, the opening at the input port 311 is enlarged to increase the gas flow rate, ensuring that the output pipe 331 used can output gas for atomization treatment. When the gas flow is guaranteed, the supply of gas flow is guaranteed, that is, the more the output ports are opened, the larger the opening of the input port 311 is, and the greater the flow rate is; when it is no longer needed, the opening and closing part 34 is rotated in the opposite direction, the traction rod 344 is retracted to relax the pull rope 352, and the tension spring 354 is retracted at this time to keep the pull rope 352 in a straight state. At the same time, the tension spring 354 can pull the shielding piece 351 back until the input port 311 is in a closed state again, and the shielding piece 351 returns to its original position and continues to shield the input port 311. The driving of the entire shielding piece 351 does not require external force or other power equipment, but can be completed by using the opening and closing part 34. The overall structural design is ingenious, simple to use, and low cost. The cooperation between the opening and closing part 34 and the adjustment part 35 can achieve multiple functions through a simple structure.

[0041] The second embodiment, referring to Figures 2 to 5As shown, the input port 311 is located in the middle position of the main body 31, the number of shielding sheets 351 is set to an even number, the shielding sheets 351 are evenly divided into two groups, the number of pull ropes 352 and traction rods 344 are consistent with the number of shielding sheets 351, and the number of tension springs 354 is half of the number of shielding sheets 351, and the guide rope group includes two first rotating shafts 3531 and two second rotating shafts 3532. The two groups of shielding sheets 351 are arranged on both sides of the input port 311 in the horizontal direction, and the two groups of shielding sheets 351 are distributed sequentially in the vertical direction. The connection between the shielding sheets 351 and the main body 31 is consistent with the first embodiment, which will not be repeated here. The opposing ends of the two groups of shielding sheets 351 extend in the lateral direction toward the input port 311 so that when the output port is in a closed state, the two groups of shielding sheets 351 respectively block one-third of the input port 311. Each output tube 331 is also divided into two groups in the same manner as the shielding sheets 351. The two groups of shielding sheets 351 are symmetrically distributed with the center line of the connecting tube 321 as the axis, and the output tubes 331 are evenly spaced. The pull rope 352 is also divided into two groups, and the guide rope group is also divided into two groups. Each guide rope group has a first rotating shaft 3531 and a second rotating shaft 3532. The two first rotating shafts 3531 and the two second rotating shafts 3532 are symmetrically distributed on both sides of the main body 31 with the center line of the connecting tube 321 as the axis, and the distance between the two first rotating shafts 3531 is greater than the distance between the two second rotating shafts 3532. The spacing between the two second rotating shafts 3532 and the surface where the input port 311 of the main body 31 is located is greater than the spacing between the first rotating shaft 3531 and the surface where the input port 311 of the main body 31 is located. The two groups of pull ropes 352 are respectively connected to the two groups of shielding plates 351 and then bypass the two groups of guide rope groups and are connected to the traction rod 344 to form a "Z" shaped routing, respectively. The arrangement between the pull rope 352, the first rotating shaft 3531, the second rotating shaft 3532, the shielding plate 351 and the traction rod 344 is the same as the arrangement of the first embodiment, and will not be described in detail here.

[0042] Preferably, in order to prevent the pull rope 352 from sliding and shifting after passing around the first rotating shaft 3531 and the second rotating shaft 3532 and causing the pull rope 352 to be entangled with each other, guide ring grooves 3533 corresponding to the number of tension springs 354 are formed on the first rotating shaft 3531 and the second rotating shaft 3532. The guide ring grooves 3533 are recessed along the outer wall of the first rotating shaft 3531 and the second rotating shaft 3532 in the circumferential direction to form an annular groove body. Each pull rope 352 is wound in the guide ring groove 3533, so as to limit the pull rope 352 and prevent the pull rope 352 from being entangled with each other due to sliding during the pulling process, thereby ensuring the normal use of the adjustment part 35.

[0043] Reference Figures 3 to 7As shown, preferably, a reset portion 36 is provided on the output tube 331, which is used to block the sealing piece 342 when the sealing plug 332 blocks the connecting port 333 to prevent the output port from being opened due to the accidental twisting of the knob 343. When the threaded tube 242 is connected to the connecting port 333 and the squeezing tube 243 squeezes the sealing plug 332 to open the sealing plug 332, the reset portion 36 is triggered to allow the main shaft 341 to rotate. At the same time, the reset portion 36 can automatically reset the main shaft after the connecting joint 24 is removed to prevent forgetting to close the output port.

[0044] Specifically, the reset portion 36 includes a first air channel 361 formed in the tube wall of the output tube 331, a second air channel 362 formed in the tube wall of the output tube 331, a first elastic portion 363 slidably and sealedly arranged in the first air channel 361, and a second elastic portion 364 slidably and sealedly arranged in the second air channel 362. The first ends of the first air channel 361 and the second air channel 362 both penetrate the inner wall of the output tube 331 near the connecting port 333, and the second ends of the first air channel 361 and the second air channel 362 both penetrate the inner wall of the output tube 331 near the output port.

[0045] The first elastic portion 363 includes a first extrusion plug 3631 and a second extrusion plug 3632 which are respectively slidably and sealingly arranged at two ends of the first air channel 361, a first spring 36331 connected to the first extrusion plug 3631 at one end, and a second spring 36332 connected to the second extrusion plug 3632 at one end. The other ends of the first spring 36331 and the second spring 36332 are connected to the inner wall of the first air channel 361. One end of the first extrusion plug 3631 and the second extrusion plug 3632 away from the first spring 36331 and the second spring 36332 can slide out of the first air channel 361 through the end of the first air channel 361. The first extrusion plug 3631 is located at one end of the first air channel 361 close to the connecting port 333, and the second extrusion plug 3632 is located at one end of the first air channel 361 close to the output port. The first extrusion plug 3631 is arranged parallel to the output pipe 331, and the second extrusion plug 3632 is arranged perpendicular to the output pipe 331. When the sealing plug 332 blocks the connection port 333, the first extrusion plug 3631 near the connection port 333 is squeezed into the first air channel 361 by the sealing plug 332. At this time, the first spring 36331 is in a compressed state, and the second extrusion plug 3632 is pushed by the gas in the first air channel 361 after the first extrusion plug 3631 moves toward the first air channel 361, and the end of the second extrusion plug 3632 extends out of the first air channel 361. At this time, the second spring 36332 is in a stretched state, and one end of the second extrusion plug 3632 after extending out of the first air channel 361 is located in the sealing state. Within the rotation radius of the blocking piece 342, at this time, the blocking piece 342 blocks the output port, and the second extrusion plug 3632 presses against the blocking piece 342. Under the restriction of the limit block 313, the blocking piece 342 limits the blocking piece 342 so that it cannot rotate, thereby preventing the patient from accidentally opening the blocking piece 342 when the blocking plug 332 is in a closed state, thereby avoiding the corresponding blocking piece 342 from opening due to the accidental opening of the output port, thereby increasing the flow at the input port 311 and causing the air volume in the main body 31 to increase, and at the same time avoiding the unused output tube 331 from affecting the airflow after being accidentally opened. When the sealing plug 333 is pushed open by the squeezing tube 243 to open the connecting port 333, the sealing plug 332 moves away from the first squeezing plug 3631 and no longer squeezes the first squeezing plug 3631. After being freed from the restraint, the first squeezing plug 3631 is squeezed by the first spring 36331 and extends out of the first airway 361. The second squeezing plug 3632 retracts into the first airway 361 under the action of the gas in the first airway 361 and the compression of the second spring 36332. In this way, the sealing piece 342 can be rotated at will to open the output port until the sealing plug 332 closes at the connecting port 333 again to squeeze the first squeezing plug 3631.

[0046] The second elastic portion 364 includes a third squeeze plug 3641 and a fourth squeeze plug 3642 which are respectively slidably and sealingly arranged at two end positions of the second air channel 362, a third spring 36431 connected to the third squeeze plug 3641 at one end, and a fourth spring 36432 connected to the fourth squeeze plug 3642 at one end. The other ends of the third spring 36431 and the fourth spring 36432 are respectively connected to the inner wall of the second air channel 362. One end of the third squeeze plug 3641 and the fourth squeeze plug 3642 away from the third spring 36431 and the fourth spring 36432 can extend out of the second air channel 362 toward the end of the second air channel 362. The third squeeze plug 3641 is arranged perpendicular to the output pipe, and the fourth squeeze plug 3642 is arranged parallel to the main shaft 341. The third squeeze plug 3641 is located at one end of the second air channel 362 close to the connecting port, and the fourth squeeze plug 3642 is located at one end of the second air channel 362 close to the output port. When the sealing plug 332 blocks the connection port 333, the third spring 36431 and the fourth spring 36432 are both in a normal state. At this time, the end of the third extrusion plug 3641 away from the third spring 36431 passes out of the second airway 362 to extend into the output pipe 331, and the fourth extrusion plug 3642 is located in the second airway 362. When the extrusion tube 243 enters the output pipe 331 and the sealing plug 332 is opened, the sealing plug 332 turns toward the third extrusion plug 3641. When the sealing plug 332 contacts the third extrusion plug 3641, the threaded tube 242 has not been installed yet, and the extrusion tube 243 continues to move into the output pipe 331. The sealing plug 332 squeezes the third extrusion plug 3641 to make the third extrusion plug 3641 slide toward the second airway 362, the third spring 36431 is compressed, and the fourth extrusion plug 3642 is pressed by the second airway 362. The gas is squeezed and slides toward the outside of the second airway 362 and gradually passes through the outside of the second airway 362 to enter the output tube 331. At this time, the fourth spring 36432 is in a stretched state; until the extrusion tube 243 completely enters the output tube 331, at this time, the sealing plug 332 abuts against the extrusion tube 243, and the third extrusion plug 3641 abuts against the sealing plug 332, and the position of the fourth extrusion plug 3642 is located within the rotation radius of the sealing piece 342 and corresponds to the position corresponding to the opening state of the sealing piece 342 to limit the rotation of the main shaft 341. When the extrusion tube 243 exits the connection port 333, the third extrusion plug 3641 and the fourth extrusion plug 3642 are reset under the action of the third spring 36431, and the fourth extrusion plug 3642 no longer restricts the sealing piece 342.

[0047] Preferably, a second torsion spring is provided on the main shaft 341, and two torsion arms of the second torsion spring are respectively connected to the blocking piece 342 and the inner wall of the output tube 331. When the blocking piece 342 blocks the output port, the second torsion spring is in a normal state, and when the output port is in an open state, the second torsion spring is in a compressed state. Therefore, without the restriction of the second extrusion plug 3632 and the fourth extrusion plug 3642, the second torsion spring will make the blocking piece 342 always block the output port, so as to automatically close the output port when the patient forgets to close the output port. Since the fourth extrusion plug 3642 has extended into the inner cavity of the output tube 331 after the blocking plug 332 is opened, and the output port is in a closed state at this time, when the main shaft 341 is rotated, the fourth extrusion plug 3642 will block the blocking piece 342 so that it cannot be fully opened. At the same time, after the external force is removed, the main shaft 341 will block the output port again under the action of the second torsion spring. To this end, the fourth extrusion plug 3642 includes a connecting block 36421 which is slidably and sealingly arranged in the second air channel 362, a limiting strip 36422 which is slidably arranged in the second air channel 362 and is located on the side of the connecting block 36421 away from the fourth spring 36432, and a fifth spring 36423 whose two ends are respectively connected to the connecting block 36421 and the limiting strip 36422. The limiting strip 36422 can move out of the second air channel 362 to extend into the output pipe 331. In the absence of external force, the fifth spring 36423 is in a normal state. A guiding slope 36424 is formed on one side surface of the limit strip 36422 facing the inner cavity of the output tube 331, and the blocking piece 342 is symmetrically formed with a first side and a second side relative to the main shaft 341. When the main shaft 341 rotates, the first side swings toward the inside of the output tube 331 and the second side swings toward the outside of the output tube 331. When the blocking piece 342 blocks the output port, the first side is located at the initial position. When the output port is in an open state, the second side is located at the connecting position. When the limit strip 36422 passes through the output tube 331, the limit strip 36422 is located between the initial position and the connecting position and close to the connecting position. When the first side is located at the connecting position, the limit strip 36422 presses against the first side to prevent the blocking piece 342 from rotating.The guiding slope 36424 is arranged to be inclined from low to high along a direction perpendicular to the first side at the connecting position, from the initial position toward the connecting position side, and the side of the guiding slope 36424 close to the initial position is always located in the first airway 361, so that the limiting strip 36422 rotates the main shaft 341 after extending out of the second airway 362, and the blocking piece 342 presses the guiding slope 36424 after contacting the limiting strip 36422, that is, presses the limiting strip 36422 toward the second airway 362, and at this time, the fifth spring 36423 is compressed and When the blocking piece 342 is in a compressed state, it can continue to rotate until it moves to the connected position. After the limit strip 36422 is separated from the first side, it passes through the second airway 362 under the action of the fifth spring 36423 and blocks the first side. The cooperation between the connecting block 36421, the fifth spring 36423 and the limit strip 36422 can shrink the limit strip 36422 in the second airway 362 without changing the state of the third spring 36431 where the fourth extrusion plug 3642 is located, thereby completing the swinging of the blocking piece 342.
