Description
Technical Field
[0001] The utility model relates to the technical field of humidification bottles, in particular to an oxygen humidification bottle. Background Art
[0002] The disposable oxygen humidification bottle is used for humidification of oxygen during oxygen therapy, and is usually composed of a humidification bottle body and a humidification liquid contained in the humidification bottle body, and the humidification bottle body is provided with an air inlet and an air outlet. When in use, oxygen enters the humidification bottle body from the air inlet, combines with the humidification liquid in the bottle to form a humidified gas with a certain moisture content, and flows out from the air outlet for the patient to inhale. The disposable oxygen humidification bottle in the prior art generally has an air inlet at the top of the bottle body. When in use, oxygen directly enters the bottle body from the air inlet at the top of the bottle body, resulting in insufficient contact between the gas and the humidification liquid, and insufficient humidification of the oxygen. Even if the air inlet pipe is inserted into the humidification liquid from the air inlet, since the air inlet pipe needs to maintain a certain ventilation distance with the inner bottom of the humidification bottle, it still results in insufficient contact between the gas and the humidification liquid, and insufficient humidification of the oxygen. In addition, as the usage time gradually increases, the humidifying liquid content in the bottle will gradually decrease, and the liquid level of the humidifying liquid will be lower than the bottom of the air inlet pipe. At this time, a large amount of gas will flow out directly from the air outlet without passing through the humidifying liquid, resulting in serious lack of oxygen humidity. The humidifying liquid in the bottle cannot be completely used up, thus causing waste. Utility Model Content

DETAILED DESCRIPTION
[0022] The embodiments of the present invention are described in detail below. Figures 1 to 5 The embodiment of the utility model provides an oxygen humidification bottle, including a bottle body 100, wherein a liquid storage chamber 110 for storing humidifying liquid is provided inside the bottle body 100, and an air outlet portion 120 is provided at the top of the bottle body 100, and an air outlet channel 121 is provided in the air outlet portion 120, one end of the air outlet channel 121 is connected to the liquid storage chamber 110, and the other end has an air outlet 122. An air inlet portion 200 is provided at the outer side of the bottle body 100, and the air inlet portion 200 is provided with an air inlet channel 210 and an air inlet 221, the top of the air inlet channel 210 is connected to the air inlet 221, and the bottom of the air inlet channel 210 is connected to the bottom of the liquid storage chamber 110. Figure 5The oxygen humidification bottle adopts an external structure of the air inlet 200, which is arranged around the outside of the bottle body 100 and connected to the liquid storage chamber 110 from the bottom of the bottle body 100. When in use, oxygen flows from the air inlet 221 through the air inlet channel 210, enters from the bottom of the liquid storage chamber 110, flows through the humidifying liquid in the liquid storage chamber 110, and then flows out from the air outlet 122, so that there is a larger contact area and a longer contact time between oxygen and the humidifying liquid, so that oxygen and the humidifying liquid are fully in contact, which can increase the humidification output and have better humidification performance. In addition, since oxygen enters the liquid storage chamber 110 from the bottom of the liquid storage chamber 110, as long as there is humidifying liquid in the liquid storage chamber 110, oxygen will definitely contact with the humidifying liquid first, so there is no need to put forward requirements on the liquid level height of the humidifying liquid, which can ensure that oxygen and the humidifying liquid are fully in contact, and the humidifying liquid in the bottle can be completely used up to avoid waste.
[0023] Furthermore, the oxygen humidification bottle is integrally formed and is made by a three-in-one aseptic filling technology of bottle blowing, canning and sealing. Disposable oxygen humidification bottles in the prior art are mostly assembled using multiple parts, which not only increases the difficulty of assembly and reduces work efficiency, but also requires an additional humidification liquid filling process, which not only further reduces work efficiency, but also increases the risks that may occur during assembly and filling, making it difficult to ensure the aseptic performance of the product. However, all structures of the oxygen humidification bottle in this embodiment are integrally formed, and no assembly is required, which can reduce the difficulty of assembly and improve work efficiency. It is made by a three-in-one aseptic filling technology of blowing, filling and sealing, which not only allows the humidification bottle to have the structural advantage of integral molding, but also can achieve asepticization from the production end, that is, through process management, to ensure the aseptic performance of the product, and no longer needs to perform terminal sterilization on the product, reducing the risks that may exist in terminal sterilization such as ethylene oxide residue. Furthermore, the oxygen humidification bottle is made of polyethylene or polypropylene material. The disposable oxygen humidification bottle in the prior art generally includes multiple components, and these components are made of various materials such as plastics and metals. However, the oxygen humidification bottle in this embodiment is made of only one material, polyethylene or polypropylene. The material is less and safer, and has a lower risk of use in terms of chemical properties, and also has lower risks in terms of biocompatibility and compatibility of the material with other contact substances during normal use.
[0024] Further, refer to Figure 1 and Figure 2The air inlet part 200 includes an air inlet end 220, a first air inlet pipe 230 and a second air inlet pipe 240 which are connected in sequence. The first air inlet pipe 230 and the second air inlet pipe 240 are connected to each other and are distributed in an "L" shape. The first air inlet pipe 230 is fixedly connected to the outer side of the bottle body 100, and the air inlet 221 is opened at the top of the first air inlet pipe 230. Specifically, the air inlet 221 is opened in the air inlet end 220 at the top of the first air inlet pipe 230. The second air inlet pipe 240 is fixedly connected to the bottom of the bottle body 100, and the second air inlet pipe 240 is connected to the bottom of the liquid storage chamber 110. This structure is easier to form, and the first air inlet pipe 230 is arranged at the outer side of the bottle body 100, and the second air inlet pipe 240 is arranged at the bottom of the bottle body 100, which can facilitate oxygen to enter from the bottom of the liquid storage chamber 110 after bypassing the outside of the bottle body 100, thereby increasing the contact area and contact time between oxygen and the humidifying liquid. In addition, it should be noted that the first air intake pipe 230 and the second air intake pipe 240 here can be round tubes, square tubes or flat tubes, and can also be tubes of other shapes.
[0025] Further, refer to Figure 3 and Figure 4 A plurality of third air inlet pipes 250 are connected between the side of the second air inlet pipe 240 and the bottom of the bottle body 100. A branch channel 213 is provided in the third air inlet pipe 250. The air inlet channel 210 is connected to the bottom of the liquid storage chamber 110 through the branch channels 213 of the plurality of third air inlet pipes 250. The first air inlet pipe 230 and the second air inlet pipe 240 are connected to each other and are distributed in an "L" shape, so that the second air inlet pipe 240 can be approximately parallel to the bottom of the bottle body 100, and it is convenient to arrange a plurality of third air inlet pipes 250 on the side of the second air inlet pipe 240 to connect with the liquid storage chamber 110, so that oxygen is divided into a plurality of branches, which are respectively input into the liquid storage chamber 110 through the plurality of branch channels 213, further increasing the contact area and contact time between oxygen and the humidifying liquid, so that oxygen and the humidifying liquid can be more fully contacted, and the humidification performance is further improved. Specifically, the air inlet channel 210 includes a first air channel 211 opened in the first air inlet pipe 230, a second air channel 212 opened in the second air inlet pipe 240, and a branch channel 213 opened in the third air inlet pipe 250. The first air channel 211 and the second air channel 212 are interconnected, and the second air channel 212 and the branch channel 213 are interconnected, and the branch channel 213 is interconnected with the liquid storage chamber 110. That is, the air inlet 221, the first air channel 211, the second air channel 212, the branch channel 213 and the liquid storage chamber 110 are sequentially connected.
[0026] Furthermore, the air inlet end 220 of the air inlet part 200 is connected with a first sealing part 222, and the first sealing part 222 is used to seal the air inlet 221. The air outlet end of the air outlet part 120 is connected with a second sealing part 123, and the second sealing part 123 is used to seal the air outlet 122. After the humidification bottle is made by adopting the blow-fill-seal three-in-one aseptic filling technology, the first sealing part 222 and the second sealing part 123 seal the air inlet 221 and the air outlet 122 respectively. When in use, the first sealing part 222 and the second sealing part 123 can be unscrewed or cut, and the oxygen supply tube is plugged or sleeved on the air inlet 221, and the oxygen inhalation tube is connected or sleeved on the air outlet 122, so as to be used by the patient. Further, the outer periphery of the air inlet 200 is provided with a first clamping portion 223, and the first clamping portion 223 is used to clamp and fix the oxygen supply pipe, and the outer periphery of the air outlet 120 is provided with a second clamping portion 124, and the second clamping portion 124 is used to clamp and fix the oxygen absorption pipe. Specifically, the first clamping portion 223 and the second clamping portion 124 are annular grooves or annular protrusions extending in the circumferential direction, that is, the first clamping portion 223 and the second clamping portion 124 can both be annular grooves, or both be annular protrusions. Of course, one of them can be an annular groove and the other can be an annular protrusion. In addition, the first clamping portion 223 and the second clamping portion 124 can also adopt a buckle structure as long as the oxygen supply pipe and the oxygen absorption pipe can be fixed and sealed. Further, the first clamping portion 223 and the second clamping portion 124 can be set in one circle or multiple circles. In addition, the first sealing portion 222 and the second sealing portion 123 can also be formed into a thin sheet structure. When in use, the oxygen supply tube and the oxygen absorption tube are directly used to pierce the first sealing portion 222 and the second sealing portion 123 respectively, and the oxygen supply tube and the oxygen absorption tube are respectively inserted into the air inlet 221 and the air outlet 122 for use.
