Description

Technical Field

[0001] This invention belongs to the technical field of nebulization devices, and in particular relates to a medical tubing nebulization device. Background Technology

[0002] Nebulizer therapy is a method of treating diseases by dissolving drugs in solution and then using a vaporizer, nebulizer, or atomizer to form drug vapor, mist, or aerosol for inhalation or local spraying.

[0003] There are various types of commonly used nebulizers, generally made of glass or transparent plastic. The spray section is fused to a vessel with a curved nozzle outlet, and the liquid medicine is contained at the bottom. The spray power can be generated by manual pumping or by connecting to an oxygen cylinder or compressed air cylinder. Ultrasonic nebulizers are also used, producing fine mist particles, and the volume and speed of the atomized liquid can be adjusted.

[0004] Nebulizer therapy is primarily used for respiratory diseases such as asthma and bronchitis. It is simply connected in series with the patient's oxygen supply tubing. Compared to direct injection and oral medication delivery methods, which rely on intravenous injection or digestive system delivery, nebulizer therapy provides localized drug delivery. The medication acts directly on the affected area through the respiratory system, without needing to be transported throughout the body via the bloodstream. Furthermore, the dosage is easily controlled, making it highly targeted. It also avoids the risk of medication entering the bloodstream and causing side effects.

[0005] The nebulizer structure of existing spray devices is relatively complex, with many internal bends, making them difficult to disassemble. When the nebulizer is reused, the inside of the nebulizer cannot be thoroughly cleaned, which can easily lead to cross-contamination of the medication. Summary of the Invention

[0006] The purpose of this invention is to provide a medical tubing nebulizer that solves the problems of existing nebulizers having many internal bends, making them difficult to disassemble, and causing cross-contamination of drugs when the nebulizer is reused without sufficient cleaning.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] A medical tubing nebulizer includes a hollow three-way tube with standard connection ports extending through both sides for connection in series with an oxygen pipeline, and the three-way tube also has a drug supply port that is obliquely connected.

[0009] The drug supply port is inserted with a connecting tube, which is integrally connected to the drug storage bottle. The connection between the drug storage bottle and the connecting tube has a connecting part, and the connecting part has a one-way slot. An atomizing plate is inserted into the slot, and the atomizing plate separates the connecting tube from the internal connection of the drug storage bottle.

[0010] The atomizing plate is installed in a unidirectional plug-in manner and has a plug at the tail end. The plug at the tail end has a wire groove for power supply.

[0011] Furthermore, the atomizing plate has an annular ceramic ring and an inner stainless steel diaphragm, the stainless steel diaphragm having perforations, the ceramic ring having an interface portion extending into a groove, the interface portion having a copper one-way interface, and the insert block having a first arc-shaped groove on one side corresponding to the atomizing plate for accommodating the side of the ceramic ring.

[0012] The groove has a limiting step portion for limiting the insertion position of the interface portion, and the atomizing plate and the first arc-shaped groove of the plug are installed by plugging.

[0013] Furthermore, it also includes a controller for power supply, which is connected to the tail of the plug via a wire. The free end of the wire has a plug with a terminal for insertion into a wire slot. The plug has a limiting frame corresponding to the plug insertion position. The limiting frame is used to cover the plug portion after the terminal is inserted into the wire slot. The side wall of the limiting frame has a press-type spring, and the spring has a limiting protrusion corresponding to the inner side of the limiting frame. The plug has a limiting groove that mates with the limiting protrusion.

[0014] Furthermore, the connecting part has a circular cross-section receiving groove inside the corresponding connecting part, and the connecting part has an arc-shaped profile corresponding to the connecting part. The arc-shaped profile has a second arc-shaped groove for receiving the other side of the atomizing plate for installing the atomizing plate. The part of the connecting part corresponding to the slot has a square profile, the inner sidewall of the slot has a guide groove, and the two sides of the insert have guide rails that cooperate with the guide groove.

[0015] The perforation corresponding to the diaphragm is a tapered perforation that is larger at the top and smaller at the bottom.

[0016] Furthermore, a rubber ring is installed on the side wall of the connecting pipe for fitting the connecting pipe, and the connecting pipe has a groove to accommodate the rubber ring.

[0017] Furthermore, the medicine storage bottle has a conical bottom, a liquid filling port on the upper side, and a sealing cap, which is fixed to the liquid filling port by a connecting sleeve.

[0018] The present invention has the following beneficial effects: The nebulization system of the present invention mainly uses atomizing plates. The tail of the atomizing plate is connected to a plug for insertion and engagement with a slot, which facilitates disassembly and installation. It is easy to disassemble the entire atomizing plate and separate the medicine storage bottle. The medicine storage bottle and the connecting tube are detachably connected to the three-way tube as a whole, and can be disassembled into individual parts. This facilitates overall soaking and cleaning after a single use. Soaking in alcohol or boiling in water can not only quickly achieve the purpose of sterilization, but also wash away residual medicine and avoid cross-contamination between drugs.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] like Figure 1 As shown: A medical tubing nebulizer includes a hollow three-way tube 1, which has standard connection ports through both sides for connection in series with an oxygen pipeline. The three-way tube 1 also has a drug supply port that is connected at an angle.

[0030] The medicine supply port is inserted with a connecting tube 21, which is integrally connected to the medicine storage bottle 2. The connection between the medicine storage bottle 2 and the connecting tube 21 has a connecting part 3. The connecting part 3 has a one-way slot 31. An atomizing plate 6 is inserted into the slot 31. The atomizing plate 6 separates the connecting tube 21 from the internal connection of the medicine storage bottle 2.

[0031] The atomizing plate 6 is installed via a one-way plug-in connection and has a plug 4 at the tail end. The plug 4 has a wire groove 41 at the tail end for power supply. The medicine storage bottle 2 and the connecting tube 21 are integrated into one piece, connected in the middle by a connecting part 3. The whole part and the three-way tube 1 are both supported by transparent glass material, which facilitates external observation of the atomization and the remaining medicine.

[0032] The nebulizer 6 is used to atomize the liquid medicine in the medicine storage bottle 2. The atomized medicine enters the three-way tube 1 through the connecting tube 21 and is formally connected to the oxygen system, so that the patient can receive drug intervention treatment while receiving oxygen.

[0033] The nebulization system of this invention mainly uses the nebulizer plate 6. The tail of the nebulizer plate 6 is connected to the plug 4, which is used to connect and cooperate with the slot 21, making it easy to disassemble and install. It is easy to disassemble the nebulizer plate 6 as a whole and separate the medicine storage bottle 2. The medicine storage bottle 2 and the connecting pipe 21 are detachably connected to the three-way pipe 1 as a whole, and can be disassembled into individual parts. This makes it easy to perform a whole soaking cleaning after a single use. Soaking in alcohol or boiling water can not only quickly achieve the purpose of sterilization, but also wash away residual medicine and avoid cross-contamination between medicines.

[0034] like Figures 2-4 As shown: the atomizing plate 6 has an annular ceramic ring 62 and an inner stainless steel diaphragm 63. The diaphragm 63 has a perforation 64. The ceramic ring 62 has an interface portion 61 extending into the wire groove 41. The interface portion 61 has a copper one-way interface. The insert block 4 has a first arc-shaped groove 45 on one side of the atomizing plate 6 to accommodate the side of the ceramic ring 62.

[0035] The cable groove 41 has a limiting step portion to limit the insertion position of the interface portion 61. The atomizing plate 6 and the first arc-shaped groove 45 of the plug block 4 are installed by plugging in. The inner diameter of the unidirectional interface corresponding to the interface portion 61 is the same as the outer diameter of the cable groove 41, and the outer diameter of the interface portion is the same as the diameter of the step portion. When they are plugged in, it is ensured that the external connector can be aligned and inserted into the interface portion 61.

[0036] The atomizing plate 6 is a piezoelectric ceramic plate. The stainless steel diaphragm inside can generate high-frequency vibration under voltage drive. The vibration frequency is about 1.5 million times per second. The diaphragm is covered with densely packed dot-shaped perforations to atomize the passing liquid medicine into droplet atomization forms with a particle size of 1-5 micrometers.

[0037] Meanwhile, the atomizing plate 6 and the plug block 4 are detachable plug-in installations. The atomizing plate 6 is limited on one side of the arc-shaped edge by the first arc-shaped groove 45, and the limiting effect of the slot 31 and the interface part 61 improves the limiting installation stability of the atomizing plate 6.

[0038] As a consumable product, the atomizing plate 6 is easy to disassemble and replace. The atomization principle of this invention is penetrating vibration atomization. Due to the small diameter of individual perforations, liquid medication cannot penetrate the perforations due to surface tension. The perforations on the surface of the atomizing plate 6, through their own high-frequency vibration and compression, ultimately atomize the penetrating medication. Simultaneously, undissolved solids and impurities in the medication can be filtered by the diaphragm, improving the purity of the atomized medication. However, the diaphragm 63 may experience perforation blockage after single or multiple uses, and even during cleaning, the perforations may not be clear, leading to reduced atomization efficiency of the reusable atomizing plate. Disassembling the atomizing plate 6 reduces the cost of overall replacement and facilitates immersion cleaning.

[0039] like Figure 4 As shown: It also includes a controller 5 for power supply. The controller 5 is connected to the tail of the plug block 4 via a wire 51. The free end of the wire 51 has a plug 52, and the end face of the plug 52 has a terminal 53 for insertion into the wire slot 41. The plug 52 is plugged into the plug block 4. The controller 5 not only has adjustment buttons but also a display screen and is equipped with a lithium battery to power the atomizer 6.

[0040] The plug block 4 has a limiting frame 42 at the insertion position of the plug 52. The limiting frame 42 is used to wrap around the plug 52 part after the terminal 53 is inserted into the wire groove 41. The side wall of the limiting frame 42 has a press-type spring piece 43. The spring piece 43 has a limiting protrusion 44 on the inner side of the limiting frame 42. The plug 52 has a limiting groove 54 that mates with the limiting protrusion 44. The limiting protrusion 44 is an arc-shaped protrusion, and the limiting groove 54 is an arc-shaped groove. When they mate, the connection between the plug 52 and the plug block 4 is firm, preventing the terminal 53 from easily detaching from the electrical connection after repeated insertion and removal operations. At the same time, the installation of the plug block 4 and the plug 52 is more stable. When the plug block 4 needs to be removed, press the spring piece 43 with your thumb to make the limiting protrusion 44 engage with the limiting groove 54, and then insert or remove the plug 52 and the plug block 4 as a whole. This prevents the plug block 4 from being difficult to remove from the slot 31 if the plug 52 is pulled out directly during the insertion and removal process.

[0041] like Figure 5As shown: the interior of the connecting part 3 has a circular cross-section receiving groove corresponding to the connecting point. The connecting part 3 has an arc-shaped profile corresponding to the connecting point, and the arc-shaped profile has a second arc-shaped groove 32 for accommodating the other side of the atomizing plate 6 for mounting the atomizing plate 6. The part of the connecting part 3 corresponding to the slot 31 has a square profile. The inner wall of the slot 31 has a guide groove 33, and the two sides of the insert 4 have guide rails 46 that cooperate with the guide groove 33. Since the atomizing plate 6 is composed of two parts, the main body that plays the role of atomization is the diaphragm, and the side is a ceramic ring. In order to prevent the ceramic ring from blocking the internal connecting area of ​​the connecting part, thereby reducing the atomization part, a second arc-shaped groove 32 is provided to accommodate the ceramic ring 62. At the same time, the function of the second arc-shaped groove 32 and the guide groove 33 improves the sealing performance and prevents the liquid medicine from directly entering the connecting tube 21 from the side of the atomizing plate 6. The ceramic ring 62 also has a silicone gasket to improve the sealing performance.

[0042] like Figure 6 As shown: the perforation corresponding to diaphragm 63 is a tapered perforation that is larger at the top and smaller at the bottom.

[0043] like Figure 7 As shown: A rubber ring 7 is also installed on the side wall of the connecting pipe 21 for fitting the connecting pipe 21. The connecting pipe 21 has a groove 23 to accommodate the rubber ring 7. This is used to improve the sealing of the interface between the connecting pipe 21 and the tee pipe 1.

[0044] The medicine storage bottle 2 has a conical bottom, a liquid filling port on the upper side, and a sealing cap 22. The sealing cap 22 is fixed to the liquid filling port by a connecting sleeve.

[0045] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
