Description

Technical Field

[0001] This invention relates to the field of medical equipment technology, and more specifically, to a respiratory system with nebulization dose adjustment function. Background Technology

[0002] When using an oxygen delivery tube with a nebulizer, the nebulizer's tubing needs to be connected to the oxygen delivery tube to deliver the nebulized medication into the tube. However, in actual medical practice, critically ill patients are more sensitive to the dosage of nebulized medication, requiring control of the administration rate, i.e., the dose per unit time. Otherwise, it can easily trigger a stress response in the patient. To reduce patient discomfort and stress, it is generally recommended to administer a small dose initially, gradually increasing the normal administration rate as the patient adapts.

[0003] Although existing nebulizers can adjust the nebulization speed within a certain range, different critically ill patients have different sensitivities to dosage. In particular, when starting medication, the dose per unit time needs to be controlled very small, and then the normal dosage should be gradually increased according to the patient's actual condition. General nebulizers are difficult to meet the temporary medication needs of different patients.

[0004] In view of the above, this application is hereby submitted. Summary of the Invention

[0005] The purpose of this invention is to provide a respiratory system with adjustable nebulizer dosage, which can adapt to the temporary drug delivery needs of different patients. It allows for flexible adjustment of the dosage of nebulized medication per unit time, effectively reducing patient discomfort and stress response, and is particularly suitable for the medical care of critically ill patients. Furthermore, it is compatible with existing nebulizers, eliminating the need to replace existing equipment, resulting in lower costs and better versatility.

[0013] The inner cylinder and the second inner tube are coaxially arranged and fixedly connected, and the second inner tube mates with the second tube body. Along the axial direction of the second tube body, the second inner tube and the second tube body are in sliding fit. Along the circumferential direction of the second tube body, the second inner tube and the second tube body are in fixed fit.

[0014] The first inner tube is fixedly housed within the first tube body. The first inner tube and the second inner tube are spaced apart and connected by an elastic tube.

[0015] The first outlet and the second outlet are distributed at intervals along the axial direction of the second pipe body, and both the first outlet and the second outlet penetrate the side wall of the second pipe body.

[0016] The side wall of the regulating cylinder is provided with a first through hole for cooperating with the first outlet and a second through hole for cooperating with the second outlet. The first through hole and the second through hole are evenly spaced along the circumference of the regulating cylinder.

[0017] The inner cylinder has a medicine outlet on its side wall. Along the axial direction of the inner cylinder, the lengths of both the first through hole and the second through hole are greater than or equal to the length of the medicine outlet.

[0018] When the rotating column rotates, it drives the inner cylinder to move along the axial direction of the adjusting cylinder, thereby adjusting the flow area between the first and second through holes and the drug outlet.

[0019] Furthermore, the external thread of the inner cylinder is recessed on the outer side wall of the inner cylinder, the external thread of the inner cylinder is located at the end of the inner cylinder away from the rotating column, and there is a gap between the external thread of the inner cylinder and the end face of the inner cylinder away from the rotating column.

[0020] The internal thread of the adjusting cylinder protrudes from the inner side wall of the adjusting cylinder. The internal thread of the adjusting cylinder is located at the end of the adjusting cylinder away from the rotating column, and there is a gap between the internal thread of the adjusting cylinder and the end face of the adjusting cylinder away from the rotating column.

[0021] Furthermore, the end of the inner cylinder near the rotating column is a closed structure.

[0022] Furthermore, the end of the adjusting cylinder near the rotating column is a closed structure.

[0023] Furthermore, a mating hole is provided at one end of the rotating column near the adjusting cylinder, and the mating hole is coaxially arranged with the rotating column.

[0024] The wall of the mating hole is fitted with a first conductive strip and a second conductive strip. The first conductive strip and the second conductive strip extend along the axial direction of the mating hole and are respectively located on opposite sides of the wall of the mating hole.

[0025] The rotating column has a built-in power module and a signal processing unit. One pole of the power module is electrically connected to the end of the first conductive strip away from the adjusting cylinder, and the other pole of the power module is electrically connected to one pole of the signal processing unit. The other pole of the signal processing unit is electrically connected to the end of the second conductive strip away from the adjusting cylinder.

[0026] The adjusting cylinder is coaxially fixedly connected to a mating rod that matches the mating hole at one end near the rotating column. A conductive block is fixedly connected to the end of the mating rod, and the conductive block electrically connects the first conductive strip and the second conductive strip.

[0027] When the rotating column rotates, it drives the inner cylinder to move axially along the adjusting cylinder, and the conductive block slides between the first and second conductive strips. The signal detection module is used to determine the flow area between the first and second through holes and the drug outlet based on the current change.

[0028] Furthermore, the diversion container includes: a receiving cylinder, a piston, and a drive mechanism.

[0029] The piston is fitted inside the receiving cylinder, and the drive mechanism is used to drive the piston to move axially along the receiving cylinder.

[0030] The signal detection module is used to set the movement speed of the drive mechanism's piston based on the determined flow area between the second through hole and the drug outlet.

[0031] Furthermore, the inner wall of the accommodating cylinder is provided with a mating groove, which extends along the axial direction of the accommodating cylinder. The mating groove is provided with teeth distributed along its length direction, the height of the teeth being the same as the depth of the mating groove, and the width of the teeth being the same as the width of the mating groove.

[0033] The motion seat has an inner cavity, and a notch is provided on the side wall of the motion seat that communicates with the inner cavity. The drive gear is installed in the notch and meshes with the teeth in the mating groove. The lead screw and the driver are installed in the inner cavity of the motion seat. The lead screw is driven by the driver and the drive gear.

[0034] The beneficial effects of the technical solutions in the embodiments of the present invention include:

[0035] The respiratory system with nebulized dosage adjustment function provided in this embodiment of the invention adjusts the ratio of nebulized medication between the first and second outlets according to the actual situation when administering medication to a patient. This achieves diversion of the nebulized medication produced by the nebulizer, further reducing the dosage of nebulized medication entering the oxygen delivery tube per unit time, thereby reducing patient discomfort and stress response. After the patient adapts, the dosage per unit time is gradually increased, and the administration rate is gradually restored.

[0036] Initially, the nebulized medication entering the second outlet is collected by the shunt container, thus reducing the dose entering the oxygen delivery tube. After gradually resuming normal medication administration, the shunt container can be controlled to expel the previously collected nebulized medication, allowing the nebulized medication to return from the second outlet to the first outlet.

[0037] In summary, the respiratory system with nebulized dose adjustment function provided in this invention can adapt to the temporary drug administration needs of different patients, flexibly adjust the unit time dose of nebulized drugs, effectively reduce patient discomfort and stress response, and is particularly suitable for medical care of critically ill patients. Furthermore, it is compatible with existing nebulizers, eliminating the need to replace existing equipment, resulting in lower costs and better versatility. Attached Figure Description

Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0049] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0052] Furthermore, the terms "parallel" and "perpendicular" do not imply that components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be perfectly parallel, but that it can be slightly tilted.

[0053] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0054] Please refer to Figures 1 to 7 This embodiment provides a respiratory system 1000 with nebulization dose adjustment function. The respiratory system 1000 includes a dose adjustment module 100 and a shunt container 300.

[0055] The dosage adjustment module 100 has an inlet 110, a first outlet 120, a second outlet 130, and a diversion unit 200. The inlet 110 is connected to a nebulizer (not shown in the figure), the first outlet 120 is connected to an oxygen delivery tube (not shown in the figure), and the second outlet 130 is connected to a diversion container 300. The diversion unit 200 is used to adjust the ratio of the nebulized medication between the first outlet 120 and the second outlet 130.

[0056] The diversion container 300 is capable of drawing in and expelling atomized medication.

[0057] When administering medication to patients, the ratio of the nebulized medication between the first outlet 120 and the second outlet 130 is adjusted according to the actual situation. This splits the nebulized medication output from the nebulizer, further reducing the dose of medication entering the oxygen delivery tube per unit time, thereby minimizing patient discomfort and stress response. Once the patient has adapted, the dose per unit time is gradually increased, and the administration rate is gradually restored.

[0058] Initially, the nebulized medication entering the second outlet 130 is collected by the shunt container 300, thus reducing the dose entering the oxygen delivery tube. After gradually resuming normal medication administration, the shunt container 300 can be controlled to discharge the previously collected nebulized medication, allowing it to return from the second outlet 130 to the first outlet 120. Optionally, the nebulized medication in the shunt container 300 can also be discharged at the end of the oxygen delivery process; this can be flexibly chosen based on the actual situation and is not limited to this.

[0059] Overall, the 1000 respiratory system with nebulizer dose adjustment can adapt to the temporary drug delivery needs of different patients. It can flexibly adjust the unit dose of nebulized drugs, effectively reducing patient discomfort and stress response, making it particularly suitable for the medical care of critically ill patients. In addition, it is compatible with existing nebulizers, eliminating the need to replace existing equipment, resulting in lower costs and better versatility.

[0060] In this embodiment, the diversion unit 200 includes: a first tube 210, a second tube 220, a rotating column 230, an adjusting cylinder 240, an inner cylinder 250, a first inner tube 260, and a second inner tube 270.

[0061] The first tube 210 and the second tube 220 have the same diameter. The first tube 210 and the second tube 220 are coaxially arranged and fixedly connected. The rotating column 230 is located at the end of the second tube 220 away from the first tube 210 and is coaxially arranged with the second tube 220. The rotating column 230 is rotatably fitted to the second tube 220.

[0062] The adjusting cylinder 240 is rotatably housed in the second tube 220 and fixedly connected to the rotating column 230. Rotating the rotating column 230 drives the adjusting cylinder 240. The outer wall of the adjusting cylinder 240 fits against the inner wall of the second tube 220, and the adjusting cylinder 240 has internal threads. The inner cylinder 250 is housed in the adjusting cylinder 240 and has external threads. The inner cylinder 250 and the adjusting cylinder 240 are threadedly engaged, and the outer wall of the inner cylinder 250 fits against the inner wall of the adjusting cylinder 240.

[0063] The inner cylinder 250 and the second inner tube 270 are coaxially arranged and fixedly connected, and the second inner tube 270 is fitted with the second tube body 220. Along the axial direction of the second tube body 220, the second inner tube 270 and the second tube body 220 are in sliding fit. Along the circumferential direction of the second tube body 220, the second inner tube 270 and the second tube body 220 are in fixed fit.

[0064] The first inner tube 260 is fixedly housed within the first tube body 210. The first inner tube 260 and the second inner tube 270 are spaced apart and connected by an elastic tube 280. The elastic tube 280 can be elastically stretched along the axial direction.

[0065] The first outlet 120 and the second outlet 130 are distributed at intervals along the axial direction of the second tube 220. Both the first outlet 120 and the second outlet 130 penetrate the side wall of the second tube 220. The first outlet 120 is located on the side of the second outlet 130 away from the rotating column 230.

[0066] The side wall of the regulating cylinder 240 is provided with a first through hole 241 for cooperating with the first outlet 120 and a second through hole 242 for cooperating with the second outlet 130. The first through hole 241 and the second through hole 242 are evenly spaced along the circumference of the regulating cylinder 240.

[0067] A medicine outlet 251 is provided on the side wall of the inner cylinder 250, and the medicine outlet 251 is located on the same side as the first outlet 120 and the second outlet 130. Along the axial direction of the inner cylinder 250, the lengths of both the first through hole 241 and the second through hole 242 are greater than or equal to the length of the medicine outlet 251.

[0068] When the rotating column 230 rotates, the adjusting cylinder 240 rotates together. When the adjusting cylinder 240 rotates, it drives the inner cylinder 250 to move axially through the thread. When the inner cylinder 250 moves axially along the adjusting cylinder 240, it can adjust the flow area between the first through hole 241 and the second through hole 242 and the drug outlet 251.

[0069] With this design, the flow area between the first through hole 241 and the second through hole 242 and the drug outlet 251 can be controlled by rotating the rotating column 230.

[0070] The external thread of the inner cylinder 250 is recessed on the outer side wall of the inner cylinder 250. The external thread of the inner cylinder 250 is located at the end of the inner cylinder 250 away from the rotating column 230, and there is a gap between the external thread of the inner cylinder 250 and the end face of the inner cylinder 250 away from the rotating column 230.

[0071] The internal thread of the adjusting cylinder 240 protrudes from the inner side wall of the adjusting cylinder 240. The internal thread of the adjusting cylinder 240 is located at the end of the adjusting cylinder 240 away from the rotating column 230, and there is a gap between the internal thread of the adjusting cylinder 240 and the end face of the adjusting cylinder 240 away from the rotating column 230.

[0072] This provides movement restriction for the inner cylinder 250 to move along the axis of the adjusting cylinder 240, preventing the inner cylinder 250 from coming out of the adjusting cylinder 240.

[0073] Furthermore, the inner cylinder 250 has a closed structure at the end near the rotating column 230. The adjusting cylinder 240 also has a closed structure at the end near the rotating column 230. This effectively reduces the loss of the atomized agent.

[0074] In this embodiment, a mating hole 231 is provided at one end of the rotating column 230 near the adjusting cylinder 240, and the mating hole 231 is coaxially arranged with the rotating column 230.

[0075] The wall of the mating hole 231 is fitted with a first conductive strip 232 and a second conductive strip 233. The first conductive strip 232 and the second conductive strip 233 extend along the axial direction of the mating hole 231 and are respectively disposed on opposite sides of the wall of the mating hole 231.

[0076] The rotating column 230 has a built-in power module 234 and a signal processing unit 235. One pole of the power module 234 is electrically connected to the end of the first conductive strip 232 away from the adjusting cylinder 240. The other pole of the power module 234 is electrically connected to one pole of the signal processing unit 235. The other pole of the signal processing unit 235 is electrically connected to the end of the second conductive strip 233 away from the adjusting cylinder 240.

[0077] The adjusting cylinder 240 is coaxially fixedly connected to one end near the rotating column 230 with a mating rod 243 that is adapted to the mating hole 231. The end of the mating rod 243 is fixedly connected with a conductive block 244. The conductive block 244 electrically connects the first conductive strip 232 and the second conductive strip 233 to form a closed circuit.

[0078] When the rotating column 230 rotates, it drives the inner cylinder 250 to move axially along the adjusting cylinder 240, and the conductive block 244 slides between the first conductive strip 232 and the second conductive strip 233. The signal detection module is used to determine the flow area between the first through hole 241 and the second through hole 242 and the drug outlet 251 based on the current change.

[0079] The first conductive strip 232 and the second conductive strip 233 can be resistance wires, but are not limited to them. As the conductive block 244 slides between the first conductive strip 232 and the second conductive strip 233, the lengths of the first conductive strip 232 and the second conductive strip 233 connected to the circuit are different, thereby changing the magnitude of the current in the circuit.

[0080] The signal detection module can determine the position of the conductive block 244 between the first conductive strip 232 and the second conductive strip 233 based on the change in current, thereby indirectly determining the position of the inner cylinder 250 within the regulating cylinder 240, and thus determining the position of the medicine outlet 251. In this way, the flow area between the first through hole 241 and the second through hole 242 and the medicine outlet 251 can be determined.

[0081] In other words, by monitoring the changes in current in the circuit, the connection between the first through hole 241 and the second through hole 242 and the drug outlet 251 can be determined, thereby determining the distribution ratio of the atomized drug between the first through hole 241 and the second through hole 242.

[0082] This can serve as a basis for adjusting the distribution ratio of the atomized agent between the first through-hole 241 and the second through-hole 242.

[0083] Furthermore, the diversion container 300 includes: a receiving cylinder 310, a piston 320, and a drive mechanism 330.

[0084] The piston 320 is fitted inside the accommodating cylinder 310, and the driving mechanism 330 is used to drive the piston 320 to move axially along the accommodating cylinder 310.

[0085] The signal detection module is used to set the movement speed of the drive mechanism 330 driving piston 320 based on the determined flow area between the second through hole 242 and the drug outlet 251.

[0086] In this way, the speed at which the piston 320 draws in the atomized drug can be matched with the amount of atomized drug distributed between the first through hole 241 and the second through hole 242, thereby helping to distribute the atomized drug more accurately between the first through hole 241 and the second through hole 242 and improving the accuracy of metering control.

[0087] Specifically, the inner wall of the accommodating cylinder 310 is provided with a mating groove 311, which extends axially along the accommodating cylinder 310. Teeth 312, distributed along the length of the mating groove 311, are provided within it. The height of the teeth 312 is the same as the depth of the mating groove 311, and the width of the teeth 312 is the same as the width of the mating groove 311. Along the axial direction of the accommodating cylinder 310, the length of the piston 320 is greater than or equal to the width of five teeth 312. Through this design, the piston 320 can still achieve a seal.

[0088] The drive mechanism 330 is connected to the side of the piston 320 away from the inlet end 110 of the receiving cylinder 310. The drive mechanism 330 includes: a motion seat 331, a drive gear 332, a lead screw 333, and a driver 334. The motion seat 331 is fixedly connected to the piston 320, and the motion seat 331 is slidably fitted into the receiving cylinder 310.

[0089] The motion seat 331 has an inner cavity, and a notch communicating with the inner cavity is opened on the side wall of the motion seat 331. The drive gear 332 is installed in the notch and meshes with the teeth 312 in the mating groove 311. The lead screw 333 and the driver 334 are installed in the inner cavity of the motion seat 331. The lead screw 333 is in a transmission engagement with the driver 334, and the lead screw 333 is in a transmission engagement with the drive gear 332. Through this design, the movement accuracy of the piston 320 within the receiving cylinder 310 can be effectively improved.

[0090] It should be noted that when drawing in and discharging the atomized drug, the driving speed of the driver 334 can be set according to actual needs, thereby controlling the speed of drawing in and discharging the atomized drug.

[0091] In summary, the respiratory system 1000 with nebulized dose adjustment function provided in this embodiment of the invention can adapt to the temporary drug administration needs of different patients, flexibly adjust the unit time dose of nebulized drugs, effectively reduce patient discomfort and stress response, and is particularly suitable for medical care of critically ill patients. Furthermore, it is compatible with existing nebulizers, eliminating the need to replace existing equipment, resulting in lower costs and better versatility.
