Abstract

This invention discloses a novel anti-chip humidification bottle and sealing method, belonging to the technical field of artificial oxygen delivery equipment. The humidification bottle includes a fused-sealed cap and a fused-sealed body. The fused-sealed cap has an oxygen inlet and an oxygen outlet, and a cap edge at its bottom. The bottle mouth of the fused-sealed body has a bottle mouth fixing edge, the top of which fits against the bottom of the cap edge, and both the bottle mouth fixing edge and the cap edge are engaged with the inner surface of a fused-sealing ring.

Description

Technical Field

[0001] This invention belongs to the technical field of artificial oxygen delivery equipment, and specifically relates to a novel anti-chip humidification bottle and sealing method. Background Technology

[0002] Oxygen released from oxygen cylinders or central oxygen supply pipelines has a very low humidity, generally around 4%, and often needs to be humidified before inhalation. Traditional oxygen humidification devices, due to issues such as the reusability of humidification bottles leading to cross-infection, and the noise level affecting patient rest, are gradually being replaced by disposable oxygen humidification devices. Disposable oxygen humidification devices typically use disposable plastic bottles, with the humidifying solution pre-filled inside. To use, simply tear open the outer packaging and connect the device; this ensures one-time use and avoids cross-infection between patients.

[0003] The humidifying solution in a single-use humidification bottle should be sterile as required. Sterile products should, whenever possible, undergo final sterilization using heating methods. Typical sterilization parameters include 115°C saturated steam sterilization for 30 minutes or 121°C saturated steam sterilization for 20 minutes, both of which involve relatively high sterilization temperatures. To withstand such high sterilization temperatures, humidification bottles are generally made of polypropylene (PP), a material with good heat resistance.

[0004] To ensure the sterility of the humidification solution, the humidification bottle must be completely sealed. Ordinary threaded seals are prone to leakage during high-temperature sterilization because the slight expansion and contraction of the bottle opening can cause the cap to loosen. Adhesive sealing is also unsuitable because most adhesives have a working temperature range of -40 to 100°C and cannot withstand the high temperatures of heat sterilization. Therefore, conventional threaded seals and adhesive sealing are not suitable for sealing sterile oxygen delivery devices.

[0005] Currently, the main methods for sealing high-temperature sterilization bottles are ultrasonic welding and spin sealing. Ultrasonic welding works by applying high-frequency mechanical vibrations generated by ultrasonic waves to the welding surface. Friction between molecules on the welding surface raises the interface temperature. When the temperature reaches the material's melting point, the weld melts, fusing the bottle mouth and cap together to achieve a seal. Spin sealing utilizes a rotary welding machine to apply pressure and high-speed rotation to the bottle mouth, causing the contact surface between the cap and mouth to melt due to frictional heat in a very short time, achieving a weld. Since both ultrasonic welding and spin sealing rely on frictional heat to achieve a weld, both involve friction on the welding surface. In the initial welding stage, before the material melts, friction generates a large amount of plastic debris. This debris easily falls into the humidification bottle, contaminating the humidification solution and ultimately causing product spoilage. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a novel anti-chip humidification bottle and sealing method to solve the problem of plastic chips generated during welding falling into the humidification bottle and causing the humidification liquid to be wasted.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a novel anti-dandruff humidification bottle, comprising a fused-sealed cap and a fused-sealed bottle body, wherein the inside of the fused-sealed cap and the bottle mouth surface of the fused-sealed bottle body are provided with matching threads, the fused-sealed cap is provided with an oxygen inlet end and an oxygen outlet end, and the bottom of the fused-sealed cap is provided with a cap edge; the bottle mouth of the fused-sealed bottle body is provided with a bottle mouth fixing edge, the top of the bottle mouth fixing edge is fitted with the bottom of the bottle cap edge, and both the bottle mouth fixing edge and the bottle cap edge are sleeved with the inner annular surface of the fused-sealing ring.

[0008] More preferably, in the novel anti-dandruff humidifying bottle described above, the diameter of the bottle cap edge is smaller than the diameter of the bottle mouth fixing edge, and the interior of the sealing ring is a two-stage inverted step type. The first step from top to bottom serves as the sealing part one and fits with the bottle cap edge, and the second step serves as the sealing part two and fits with the bottle mouth fixing edge.

[0009] More preferably, in the novel anti-dandruff humidification bottle described above, the oxygen inlet includes an external air inlet pipe, which is connected to an internal connecting pipe in the internal channel of the fused cap, and the inlet of the external air inlet pipe is provided with an easy-pull or easy-break opening.

[0010] In a further preferred embodiment, the novel anti-dandruff humidifying bottle described above has an external air inlet pipe and an internal connecting pipe connected by a detachable sleeve connection.

[0011] More preferably, in the novel anti-dandruff humidification bottle described above, the lower end of the internal connecting tube is provided with a bubble-type humidifier that can disperse oxygen into fine bubbles.

[0012] More preferably, in the novel anti-dandruff humidifying bottle described above, the bubble humidifier includes a diaphragm and a diaphragm cover for fixing the diaphragm, and the side of the diaphragm cover that contacts the diaphragm is provided with several guide grooves.

[0013] More preferably, in the novel anti-dandruff humidification bottle described above, the oxygen outlet end includes an outlet pipe that connects to the interior of the sealed bottle body, and the outlet of the outlet pipe is provided with an easy-pull or easy-break opening.

[0014] More preferably, in the novel anti-dandruff humidifying bottle described above, the sealing cap, sealing body, and sealing ring are made of plastic, preferably polypropylene.

[0015] In addition, the present invention also provides a sealing method for the above-mentioned novel anti-dandruff humidification bottle, the method comprising the following steps:

[0016] S1. Filling the humidifying solution: The humidifying solution is filled into the inside of the sealed bottle using filling equipment;

[0017] S2. Install the sealing ring: Place the sealing cap on the bottle mouth of the sealing bottle body, tighten it so that the top of the bottle mouth fixing edge fits with the bottom of the bottle cap edge, and then put the sealing ring on the bottle mouth fixing edge and the bottle cap edge.

[0018] S3. Melting and sealing bottle cap and bottle body: The melting and sealing ring is pressed by a spin melting machine and rotated at high speed. The melting and sealing parts one and two of the melting and sealing ring are heated by friction with the edge of the bottle cap and the fixed edge of the bottle mouth, respectively, and then fused together to form a melting and sealing surface, which plays a sealing role.

[0019] S4. Sterilize the sealed humidification bottle with saturated steam at 115℃-121℃ for 20-30 minutes, preferably 30 minutes at 115℃ or 20 minutes at 121℃.

[0020] As a preferred technical solution of the sealing method of the present invention, a first sealing surface is formed between the first sealing part and the edge of the bottle cap, and a second sealing surface is formed between the second sealing part and the fixed edge of the bottle mouth. The first sealing surface is a plane, an inclined surface or an arc surface, and the second sealing surface is a plane, an inclined surface or an arc surface.

[0021] As a preferred embodiment of the sealing method of the present invention, the rotation speed of the spin welding machine in step S3 is 450-550 revolutions per minute, and the number of rotations of the sealing ring is 4-6 revolutions.

[0022] Compared with the prior art, the present invention provides a novel anti-dandruff humidifying bottle and sealing method, which has the following beneficial effects: By setting a fusion-sealing cap, a fusion-sealing bottle body, and a fusion-sealing ring, the fusion-sealing cap and the fusion-sealing bottle body are first screwed together. Since the diameter of the fixed edge below the bottle mouth thread is larger than the diameter of the bottle cap edge, after the bottle mouth is tightened, an annular step is formed between the bottle cap edge and the bottle mouth fixed edge. A fusion-sealing ring is added at this annular step position. The interior of the fusion-sealing ring is made into a two-stage inverted step shape. The first step fits with the bottle cap edge, and the second step fits with the exposed bottle mouth fixed edge. During sealing, a spin welding machine is used to press the fusion-sealing ring and make it rotate at high speed. The two stepped surfaces of the fusion-sealing ring rub against the bottle cap edge surface and the bottle mouth fixed edge surface respectively to generate heat and melt, thereby fusing them together to achieve a sealing effect. This process first screws the cap onto the bottle to prevent foreign objects from entering. Then, a spin-welding machine is used to weld a two-stage stepped sealing ring to the outer surface of the connection between the cap edge and the bottle neck. This prevents plastic debris generated during the sealing process from splashing into the bottle, effectively protecting the humidifying liquid from contamination. Experimental comparisons show that this invention effectively improves the yield of the humidifying liquid, is economically viable, and ensures the practicality of the device.

[0033] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-8 A novel anti-dandruff humidifying bottle includes a fused-sealed cap 1 and a fused-sealed bottle body 2. The inside of the fused-sealed cap 1 and the bottle mouth surface of the fused-sealed bottle body 2 are provided with matching threads. The fused-sealed cap 1 is provided with an oxygen inlet end 11 and an oxygen outlet end 13, and a cap edge 15 is provided at the bottom of the fused-sealed cap 1. A bottle mouth fixing edge 21 is provided at the bottle mouth of the fused-sealed bottle body 2, and the diameter of the cap edge 15 is smaller than the diameter of the bottle mouth fixing edge 21. When the fused-sealed cap 1 and the fused-sealed bottle body 2 are tightened together by the threads, the top of the bottle mouth fixing edge 21 fits against the bottom of the cap edge 15. Furthermore, since the diameter of the bottle neck fixing edge 21 below the bottle neck thread is larger than the diameter of the bottle cap edge 15, when the bottle neck is tightened, an annular step is formed between the bottle cap edge 15 and the bottle neck fixing edge 21. A sealing ring 3 is fitted onto this annular step. The interior of the sealing ring 3 is made into a two-stage inverted step shape. The first step serves as the sealing part 31, which fits against the bottle cap edge 15. The second step serves as the sealing part 32, which fits against the exposed bottle neck fixing edge 21. During sealing, a spin sealing machine is used to press the sealing ring and make it rotate at high speed. The two stepped surfaces of the sealing ring 3 rub against the bottle cap edge 15 and the bottle neck fixing edge 21 respectively, generating heat and melting them, thus fusing them together. That is, a near-planar, inclined, or curved sealing surface 1 is formed between the sealing part 31 and the bottle cap edge 15, and a near-planar, inclined, or curved sealing surface 2 is formed between the sealing part 32 and the bottle neck fixing edge 21, thereby achieving a sealing effect.

[0035] like Figure 3 , Figure 4As shown, in one specific technical solution of this embodiment, the oxygen inlet 11 includes an external air inlet pipe 12. The external air inlet pipe 12 is connected to the internal connecting pipe 22 through a detachable sleeve in the internal channel of the sealed bottle cap. The inlet of the external air inlet pipe 12 is provided with an easy-pull or easy-break opening 16. The opening 16 is preferably an easy-break head that is injection molded into the oxygen inlet 11. The connection is completely sealed, which can effectively avoid the pollution problem caused by poor sealing of the air inlet. In use, simply break off the opening 16 and then insert the external air inlet pipe into the oxygen flow meter.

[0036] like Figure 8 , Figure 9 As shown, in one specific technical solution of this embodiment, the lower end of the internal connecting pipe 22 is provided with a bubble-type humidifier 23 capable of dispersing oxygen into fine bubbles. The bubble-type humidifier 23 includes a diaphragm 231 and a diaphragm cover 232 for fixing the diaphragm 231. The diaphragm 231 is generally made of polytetrafluoroethylene material, with an air pore size of 0.45-0.65 μm. When oxygen passes through the diaphragm 231, it is dispersed into fine bubbles, which increases the contact surface between oxygen and the humidifying liquid, thereby achieving sufficient contact with the humidifying liquid and improving the oxygen humidification effect. The side of the diaphragm cover 232 that contacts the diaphragm 231 is designed with several guide grooves to ensure smooth flow of humidified gas. Alternatively, the structure of the bubble-type humidifier 23 of this invention can also be replaced by a gas diffusion device designed in Chinese Patent CN202961444U.

[0037] like Figure 3 , Figure 4 As shown in the figure, as a specific technical solution of this embodiment, the oxygen outlet end 13 includes an outlet pipe 14, which connects to the interior of the sealed bottle body 2. A second opening 17 is provided at the outlet of the outlet pipe 14. This second opening 17, like the first opening 16, is an easily folded head integrally molded with the oxygen outlet end 13, and the connection is completely sealed to prevent debris and bacteria from entering the humidification bottle. During use, medical personnel break off the second opening 17 of the oxygen outlet end 13 and connect it to the patient's oxygen tubing.

[0038] As a specific technical solution in this embodiment, the materials of the fusion-sealed bottle cap 1, the fusion-sealed bottle body 2 and the fusion-sealing ring 3 are plastic, preferably polypropylene (PP) material with good heat resistance, which is convenient for high-temperature sterilization of the humidification bottle.

[0039] The sealing method of the anti-dandruff humidifying bottle designed in this invention includes the following steps:

[0040] S1. Filling the humidifying liquid: The humidifying liquid is filled into the inside of the sealed bottle 2 using filling equipment;

[0041] S2. Install the sealing ring 3: Rotate the bottle mouth connection between the sealing cap 1 and the sealing bottle body 2 so that the top of the bottle mouth fixing edge 21 fits against the bottom of the bottle cap edge 15, and then put the sealing ring 3 on the bottle mouth fixing edge 21 and the bottle cap edge 15.

[0042] S3, Sealing the cap 1 and the bottle body 2: The sealing ring 3 is pressed down by a spin sealing machine and rotated at high speed. The sealing part 1 31 and the sealing part 2 32 of the sealing ring 3 are heated by friction with the edge 15 of the cap and the fixed edge 21 of the bottle mouth, respectively, and then fused together to form the sealing surface 1 and the sealing surface 2, which play a sealing role.

[0043] S4. High-temperature sterilization: Sterilize with saturated steam at 115℃ for 30 minutes or with saturated steam at 121℃ for 20 minutes.

[0044] This method first tightens the sealing cap 1 and sealing bottle body 2 with threads to prevent foreign objects from entering the bottle. Then, a spin welding machine is used to spin weld the two-stage inverted step-shaped sealing ring 3 to the outer surface of the connection between the bottle mouth fixing edge 21 and the bottle cap edge 15. This prevents plastic debris generated during the sealing process from splashing into the bottle, protecting the humidifying liquid from contamination. The experimental comparison data are shown in the table below:
