Description

Technical Field

[0001] The utility model relates to a through-type oxygen surface humidifier, belonging to the technical field of medical device products. Background Art

[0002] For existing disposable medical oxygen humidifiers, humidifying liquid is usually injected into the humidifier bottle body before leaving the factory. When the humidifying liquid contacts the inner surface of the bottle body, if the humidifying liquid contains microorganisms, they may multiply in large numbers during storage, increasing the risk of inhalation infection for patients during use. Therefore, relevant regulations clearly require that the humidifying liquid should be purified water or injection water. Even for the oxygen surface humidifying device disclosed in patent CN101966363A, no other chemical substances or drugs for achieving aseptic and antibacterial purposes should be added to the humidifying liquid; patent CN104117124A provides a control body solution to avoid inhalation of non-volatile antibacterial substances into the human body, so that the oxygen flow does not directly blow towards the wet surface. However, during transportation, the humidifying liquid will also contact the control body. After the dry oxygen takes away the moisture, the antibacterial substances may still crystallize locally and be inhaled into the human body with the air flow after falling off, especially in the case of high-flow oxygen inhalation; for existing surface humidifying devices, when the liquid level of the consumed humidifying liquid drops, the humidifying liquid delivery capacity decreases, and it is difficult to maintain a stable humidifying effect; due to the relatively complex internal structure of the oxygen humidifier bottle body and the need to withstand a background pressure of about 200 KPA in the central oxygen system when the oxygen delivery pipeline is folded and pressed, thermal sterilization of the humidifier will significantly affect the pressure resistance of the bottle body and may cause it to burst, scaring the patient; while radiation sterilization is costly and requires higher radiation resistance of materials, and the sterilization effect on liquid water is not very ideal; to ensure the safety of oxygen humidification, there is an urgent clinical need for a disposable oxygen humidifier that can provide sterile humidifying liquid without significantly increasing costs, not only eliminating the risk of microbial infection to the greatest extent, but also preventing antibacterial substances from being inhaled into the human body and truly meeting the requirements of the latest industry standards. Summary of the Invention

[0003] For the through-type oxygen surface humidifier of the utility model, after oxygen flows through the buffer space and is shunted, it enters the humidifying cavity for surface humidification, and finally provides humid and safe sterile oxygen for users.

[0004] The purpose of the utility model is realized as follows:

[0005] The through-type oxygen surface humidifier includes: a bottle body, the bottle body is provided with an oxygen inlet and an oxygen outlet. Oxygen enters the inner cavity of the bottle body through the oxygen inlet and is output through the oxygen outlet. The inner cavity of the bottle body is provided with a surface humidifying housing. The humidifying cavity inside the surface humidifying housing is communicated with the oxygen inlet. The surface humidifying housing is connected to a humidifying liquid delivery body extending to the bottom of the bottle body. A hollow through cavity is provided in the central area of the surface humidifying housing. The humidifying liquid delivery body is a hollow tube, and the through cavity of the surface humidifying housing is communicated with the inner cavity of the humidifying liquid delivery body.

[0006] At least the surface of the humidification cavity in the surface humidification shell and the inner cavity of the humidification liquid delivery body is provided with one or more structures of fibrous, porous, or fiber mesh for the capillary force transmission and adsorption of the humidification liquid.

[0007] In one solution, it further includes a support tube disposed in the inner cavity of the humidification liquid delivery body or sleeved outside the humidification liquid delivery body, and the support tube assists in stably connecting the humidification liquid delivery body and the surface humidification shell; when the support tube is located in the inner cavity of the humidification liquid delivery body, a plurality of support tube windows are opened on the support tube.

[0008] To ensure the stability of the combination of the humidification liquid delivery body and the lower part of the surface humidification shell, the surface humidification shell is formed by buckling the upper part of the surface humidification shell and the lower part of the surface humidification shell, and the humidification liquid delivery body and the lower part of the surface humidification shell are an integrally formed component.

[0009] To extend the humidification path, the surface humidification shell is formed by buckling the upper part of the surface humidification shell and the lower part of the surface humidification shell. At least the lower part of the surface humidification shell has the ability to deliver and adsorb the humidification liquid. A plurality of curved strip-shaped grooves on the upper part of the surface humidification shell and the lower part of the surface humidification shell are buckled with each other to form a plurality of humidification cavities.

[0010] In one solution, a humidification sheet with the ability to adsorb and deliver the humidification liquid is applied. The humidification sheet with a central hole is placed in the surface humidification shell, and the central hole of the humidification sheet is located in the through cavity of the surface humidification shell. The oxygen flow can enter the inner cavity of the humidification liquid delivery body through the central hole.

[0011] To increase the humidification area, the surface part of the inner cavity of the humidification liquid delivery body that adsorbs and delivers the humidification liquid is in a wrinkled shape.

[0012] To prevent the oxygen flow from entering the humidification cavity without preliminary humidification, the upper part of the surface humidification shell is provided with a hollow extension section facing the bottom of the bottle body, and the extension section extends into the through cavity in the central area of the surface humidification shell.

[0013] To further increase the humidification area provided by the humidification liquid delivery body, the inner cavity of the humidification liquid delivery body is provided with a tubular body and / or a columnar body for adsorbing and delivering the humidification liquid.

[0014] Furthermore, it further includes an insert body with the ability to adsorb and deliver the humidification liquid. The lower part of the insert body is located in the inner cavity of the humidification liquid delivery body, and the upper part of the insert body is inserted into the inner cavity of the oxygen delivery body. The shape of the insert body is one or more of rod-shaped, tubular, spiral-shaped, columnar, twist-shaped, and strip-shaped with an irregular cross-section; the insert body starts the humidification process before the oxygen enters the through cavity.

[0015] The beneficial effects of the present utility model are:

[0016] 1. The through cavity of the surface humidification shell is communicated with the inner cavity of the humidification liquid delivery body, significantly increasing the humidification area.

[0017] 2. The humidifying area of the inner cavity of the humidifying liquid delivery body increases as the humidifying liquid is consumed, and the total amount of saturated water vapor it can hold also increases synchronously, further ensuring the stability of oxygen humidification.

[0018] 3. The high-speed oxygen flow is first buffered in the space provided by the through cavity and the inner cavity of the humidifying liquid delivery body, and then split and diverted to each humidifying cavity, ensuring the uniform distribution of the airflow in the humidifying cavities.

[0019] 4. The "air cushion" - type buffer space provided by the through cavity and the inner cavity of the humidifying liquid delivery body maximally eliminates the risk of local crystal precipitation that may occur when using non - volatile antibacterial humidifying liquid.

[0020] 5. The lower part of the surface humidifying housing and the humidifying liquid delivery body are integrally formed, avoiding the risk of unstable humidifying effect caused by poor contact between the humidifying liquid delivery body and the lower part of the surface humidifying housing.

[0021] 6. The hollow extension section of the upper part of the surface humidifying housing facing the bottom of the bottle penetrates into the inner cavity of the humidifying liquid delivery body, preventing the oxygen flow from directly entering the humidifying cavity. Instead, it first enters the inner cavity of the humidifying liquid delivery body and then turns back into the humidifying cavity, further ensuring the oxygen humidifying effect.

[0022] 7. The surface part of the inner cavity of the humidifying liquid delivery body that adsorbs the humidifying liquid is in a wrinkled shape, that is, there are multiple longitudinal wrinkles that can adsorb and transport the humidifying liquid, increasing the humidifying area by several times.

[0023] 8. The tubular and columnar bodies in the inner cavity of the humidifying liquid delivery body that can adsorb and transport the humidifying liquid further increase the oxygen humidifying area provided by the humidifying liquid delivery body.

[0024] 9. The upper part of the insert body with the functions of adsorbing, permeating the humidifying liquid and transporting the humidifying liquid extends into the inner cavity of the oxygen delivery body, starting the oxygen humidification before the oxygen flow enters the humidifying cavity. The oxygen flow is also easy to flow downward along the surface of the insert body, playing a guiding role, so that more airflows enter the inner cavity of the humidifying liquid delivery body, mix with water vapor and then turn back and flow into each humidifying cavity.

[0042] The embodiments of the present utility model are not limited as follows:

[0043] Example 1:

[0044] As Figures 1A - 1C shown, a through-type oxygen surface humidifier includes: a bottle body 1 and a humidifying liquid bag 2 containing sterile humidifying liquid 0. The bottle body 1 is provided with an oxygen inlet 111 and an oxygen outlet 122. Oxygen enters the tubular oxygen delivery body 13 through the oxygen inlet 111 (such as Figure 1AThe oxygen carrier 13 of the present example is integrated with the upper part 15a of the surface humidifying housing 15), enters the inner cavity 10 of the bottle, and is then output through the oxygen outlet 122. The inner cavity 10 of the bottle is provided with a surface humidifying housing 15. The humidifying cavity 150 inside the surface humidifying housing is communicated with the oxygen inlet 111. The lower part 15b of the surface humidifying housing 15 is connected to the humidifying liquid conveyor 16 extending to the bottom of the bottle body 1 through a tubular receiving section 152. The biggest difference from the existing oxygen surface humidifying technology is that: a hollow-shaped through cavity 1500 is provided in the central area of the surface humidifying housing 15, the humidifying liquid conveyor 16 is a hollow tube, and the through cavity 1500 of the surface humidifying housing 15 is communicated with the inner cavity 160 of the humidifying liquid conveyor; a humidifying sheet 151 with a central hole 1510 is placed inside the surface humidifying housing 15, the central hole 1510 of the humidifying sheet 151 is located in the through cavity of the surface humidifying housing 15, and the oxygen flow can enter the inner cavity 160 of the humidifying liquid conveyor through the central hole 1510.

[0045] Such as Figure 1A, the bottle body 1 is formed by sealing and connecting the upper part 1a of the bottle body and the lower part 1b of the bottle body; various types of welding such as ultrasonic welding and hot melting, threaded fitting, bonding, etc. can be selected; the oxygen inlet 111 and the oxygen outlet 122 are arranged on the upper part 1a of the bottle body. The oxygen inlet 111 is opened on the hollow vertical tubular body 11 of the upper part 1a of the bottle body, and the oxygen outlet 122 is opened on the hollow horizontal tubular body 12 of the upper part 1a of the bottle body. The vertical tubular body 11 is directly or indirectly connected to the oxygen conveyor 13, and the inner cavity 130 of the oxygen conveyor is communicated with the oxygen inlet 111; external oxygen enters the inner cavity 110 of the vertical tubular body, the inner cavity 130 of the oxygen conveyor, the through cavity 1500 of the surface humidifying housing 15 (part of the oxygen enters the inner cavity 160 of the humidifying liquid conveyor), multiple inlets 1502 of the inner cavity of the surface humidifying housing, the humidifying cavities 150 in the multiple curved strip-shaped surface humidifying housings, multiple outlets 1501 of the inner cavity of the surface humidifying housing, the inner cavity 10 of the bottle body, and the inner cavity 120 of the horizontal tubular body, and then flows out through the oxygen outlet 122; the upper part 15a of the surface humidifying housing 15 and the lower part 15b of the surface humidifying housing 15, which are provided with multiple arc-shaped ribs 154, sandwich the humidifying sheet 151 therein to form multiple arc-shaped thin strip-shaped humidifying cavities 150. The humidifying sheet 151 in the arc-shaped thin strip-shaped humidifying cavity 150 contacts the oxygen conveyor 16 and adsorbs the humidifying liquid 0 from the oxygen conveyor 16. During the process that the dry oxygen flows through the humidifying cavity 150 with a longer humidifying path, the saturated water vapor on the surface of the humidifying sheet 151 is mixed into the oxygen flow, which fully improves the humidity of the oxygen and avoids the dry damage caused by inhalation into the human respiratory tract; in the existing surface humidifying technology, the total area of the humidifying sheet 151 exposed in the humidifying cavity 150 is the oxygen humidifying area. However, in the present utility model, a through cavity 1500 is provided in the central area of the surface humidifying housing 15, and the humidifying liquid conveyor 16 is a hollow tubular shape. The inner cavity 160 of the humidifying liquid conveyor is communicated with the through cavity 1500, so that the part of the inner cavity 160 of the humidifying liquid conveyor above the liquid level 01 of the humidifying liquid can be used for oxygen humidifying. Moreover, the oxygen flow, especially the oxygen flow under high flow rate (such as above 8L / Min), first passes through the through cavity 1500 and the larger space in the inner cavity 160 of the humidifying liquid conveyor for buffering and preliminary humidifying, and then evenly enters the multiple arc-shaped curved thin strip-shaped humidifying cavities 150. By increasing the total humidifying area, the humidifying effect is improved, and it also avoids the increase in resistance caused by the high-speed oxygen flow directly entering the thin strip-shaped humidifying cavity 150 without buffering; the inner cavity 160 of the humidifying liquid conveyor can accommodate saturated water vapor dozens or hundreds of times the volume of the humidifying cavity 150. The oxygen in contact is first preliminarily humidified and then enters the thin strip-shaped humidifying cavity 150 for secondary humidifying, so as to ensure a better humidifying effect. 300 control experiments show that the oxygen surface humidifier with the new structure of the through cavity 1500 and the inner cavity 160 of the humidifying liquid conveyor has better humidity than the oxygen surface humidifier without the through cavity 1500 and the inner cavity 160 of the humidifying liquid conveyor under the common oxygen flow rate (2 - 10L / Min).

[0046] The oxygen flow first passes through the through cavity 1500 and the relatively large space inside the humidifying liquid delivery body cavity 160 for buffering, which is essentially different from the regulator described in Patent CN104117124A. The regulator directly horizontally diverts the vertically flowing oxygen to multiple humidifying cavities. Although it avoids the crystallization and precipitation of antibacterial substances in the humidifying cavities, the humidifying liquid on the surface of the regulator will precipitate antibacterial substances due to the rapid evaporation caused by the direct blowing of dry oxygen, and the humidifying liquid will inevitably contact and remain on the surface of the regulator during transportation. When the liquid level of the humidifying liquid significantly drops below the lowest water level line during use, if the humidifier is not replaced in time as required, in addition to the reduction of the oxygen humidifying effect, the insufficient delivery of the humidifying liquid 0 will also cause the humidifying liquid at the starting point of the humidifying cavity 150 to be dried by the high-speed oxygen flow, thus precipitating antibacterial substances. Even if a non-volatile humidifying liquid antibacterial system with a higher concentration is used in the present invention, the oxygen flow first vertically enters the humid buffer space, and the buffer space is the sum of the volume of the through cavity 1500 and the part of the humidifying liquid delivery body cavity 160 above the liquid level 01 of the humidifying liquid, which is dozens or even hundreds of times more than the volume of the humidifying cavity 150. The gas (oxygen and water vapor) in the buffer space is pressurized to play a "cushion" buffering effect on the newly entering oxygen flow, so that the oxygen can be better diverted into multiple strip-shaped humidifying cavities 150. Experiments show that by applying the buffer space of the present invention, even when a 10% sodium chloride solution is used as the humidifying liquid and a dry oxygen flow of 10 L / Min is continuously used for 8 hours at 20°C, no crystallization particles of sodium chloride are precipitated, ensuring safety. In the ultra-high-level microbial challenge test without adding antibacterial substances, 1,000,000 cfu of Staphylococcus aureus is added to each milliliter of purified water as the humidifying liquid, and 360 ml of humidifying liquid is used. At a flow rate of 5 L / Min, in a laminar flow hood, the microorganisms in the oxygen flowing out of the oxygen outlet of the through-type oxygen surface humidifier of the present invention are continuously dynamically detected for 24 hours (the oxygen flow is continuously introduced into sterile injection water, and then the injection water is sampled for bacterial culture). The detection result of microorganisms in the oxygen flow is 0 cfu, further reflecting the safety of the oxygen surface humidifying method (while in the traditional oxygen bubble-into-water humidifying method, a large number of Staphylococcus aureus colonies were detected within only 1 Min under the same experimental conditions).

[0047] The new structures of the through cavity 1500 and the humidifying liquid delivery body cavity 160 not only help to increase the humidity of the oxygen after surface humidification. When the humidifying liquid 0 is significantly consumed and the liquid level 01 of the humidifying liquid drops during clinical use, the ability of the humidifying liquid delivery body of the prior art to deliver the humidifying liquid decreases, resulting in a reduction in oxygen humidity. However, in the present invention, when the liquid level 01 of the humidifying liquid drops, a larger volume of the humidifying liquid delivery body cavity 160 will be exposed. The humidifying area of this part increases with the consumption of the humidifying liquid 0, and the total amount of saturated water vapor S contained also increases synchronously, further ensuring the stability of oxygen humidification; Figure 1BIt shows a state where the liquid level 01 of the humidifying liquid is relatively high, and the distance L0 between the liquid level 01 and the horizontal plane of the humidifying chamber 150 is 3 cm, while Figure 1C the liquid level 01 of the humidifying liquid is at a low level, and the distance L1 between the liquid level 01 and the horizontal plane of the humidifying chamber 150 is 9 cm, and the oxygen humidity does not decrease significantly or even increases (when using a humidifying liquid delivery body 16 with a larger inner diameter).

[0048] In each figure of the present utility model, the scattered points indicate saturated water vapor S, and the dashed arrow indicates the oxygen flow direction during use.

[0049] Embodiment 2:

[0050] As Figure 2A , Figure 2B , different from Embodiment 1, it further includes a thin-walled support tube 17 arranged in the inner cavity 160 of the humidifying liquid delivery body. The rigid support tube 17 assists the humidifying liquid delivery body 16 made of a soft material to be stably connected to the surface humidifying housing 15. When the support tube 17 is located in the inner cavity 160 of the humidifying liquid delivery body, a plurality of support tube windows 170 are opened on the support tube 17 to avoid reducing the humidifying area provided by the inner cavity 160 of the humidifying liquid delivery body to the greatest extent; of course, the support tube 17 can also be sleeved outside the humidifying liquid delivery body 16 (figure omitted).

[0051] Embodiment 3:

[0052] As Figure 3A , Figure 3B , the biggest difference from Embodiment 1 is that the lower part 15b of the surface humidifying housing 15 is connected to the humidifying liquid delivery body 16 extending to the bottom of the bottle body 1 through a tubular connecting section 152. Instead, the humidifying liquid delivery body 16 and the lower part 15b of the surface humidifying housing 15 are integrally formed, which can be made by porous sintering of polyethylene, etc.; it can also be molded from a medical resin material and a capillary water-absorbing material is attached to its inner surface, such as having one or more of a fibrous, porous, or fiber mesh structure on the surface part, and is made of polypropylene, polyurethane fiber, etc. for capillary force transmission, penetration, and adsorption of the humidifying liquid 0, etc.

[0053] The upper part 15a of the surface humidifying housing 15 can also be set to have the ability of humidifying liquid adsorption and delivery, further increasing the humidifying area.

[0054] Embodiment 4:

[0055] As Figure 4A , Figure 4BAs shown, the biggest difference from the previous embodiment is that in this example, a humidification sheet 151 is not used for humidifying oxygen. The surface humidification housing 15 is formed by snapping together the upper part 15a of the surface humidification housing and the lower part 15b of the surface humidification housing. The humidification liquid transporter 16 with the ability to adsorb and transport the humidification liquid is an integrally formed component with the lower part 15b of the surface humidification housing. Multiple humidification liquid inlets 1601 are provided at the bottom of the humidification liquid transporter 16.

[0056] The surface humidification housing 15 is formed by snapping together the upper part 15a of the surface humidification housing and the lower part 15b of the surface humidification housing. At least the lower part 15b of the surface humidification housing has the ability to transport and adsorb the humidification liquid. Multiple curved strip-shaped grooves on the upper part 15a of the surface humidification housing and the lower part 15b of the surface humidification housing snap together to form multiple humidification chambers 150. The upper part 15a of the surface humidification housing 15 can also be set to have the ability to adsorb and transport the humidification liquid, eliminating the application of the humidification sheet 151 and increasing the humidification area at the same time. In this solution, water vapor is released from all surfaces within the humidification chamber 150.

[0057] Embodiment 5:

[0058] As Figure 5A 、 Figure 5B shown, the humidification sheet 151 with a central hole 1510 is placed inside the surface humidification housing 15. The central hole 1510 of the humidification sheet 151 is located within the through cavity 1500 of the surface humidification housing 15. Oxygen flow can enter the inner cavity 160 of the humidification liquid transporter through the central hole 1510. Multiple humidification liquid inlets 1601 are provided at the bottom of the humidification liquid transporter 16. The biggest difference from the previous embodiment is that in order to increase the humidification area provided by the humidification liquid transporter 16 and improve the final humidification effect of oxygen, the surface part of the inner cavity 160 of the humidification liquid transporter that adsorbs the humidification liquid is in a wrinkled shape, that is, multiple longitudinal wrinkles 161 that can adsorb and transport the humidification liquid are provided, increasing the humidification area by several times; it can also be multiple transverse wrinkles or a villous structure protruding into the inner cavity 160 of the humidification liquid transporter for increasing the humidification area.

[0059] Embodiment 6:

[0060] As Figure 6A 、 Figure 6B shown, in order to increase the humidification area provided by the humidification liquid transporter 16, a tubular body 162 that can adsorb, penetrate, and transport the humidification liquid 0 is placed inside the inner cavity 160 of the humidification liquid transporter. The bottom of the tubular body 162 is embedded in the sleeve-shaped protruding section 18 extending upward from the bottom of the bottle body 1, so that the tubular body 162 is stably located within the inner cavity 160 of the humidification liquid transporter. The outer surface of the tubular body 162 and the surface part of the inner cavity 1620 of the tubular body both become humidification areas, significantly increasing the humidification area provided by the humidification liquid transporter 16 and ultimately increasing the oxygen humidification effect, especially when the liquid level 01 of the humidification liquid is relatively low ( Figure 6B), the tubular body 162 not only increases the humidification area but also plays a role in guiding the flow, allowing more oxygen to enter the inner cavity 160 of the humidifying liquid delivery body. The tubular body 162 with a small diameter can also penetrate into the inner cavity 130 of the oxygen delivery body (figure omitted) to advance the oxygen humidification process.

[0061] Example 7:

[0062] As Figure 7A shown, the upper part 15a of the surface humidifying housing is provided with a hollow extension section 153 facing the bottom of the bottle body 1. The extension section 153 penetrates into the inner cavity 160 of the humidifying liquid delivery body through the through cavity 1500 in the central area of the surface humidifying housing 15, preventing the oxygen flow from directly entering the humidifying cavity 150. Instead, it first enters the inner cavity 160 of the humidifying liquid delivery body and then turns back into the humidifying cavity 150, further ensuring the oxygen humidification effect. Of course, just penetrating into the through cavity 1500 without penetrating into the inner cavity 160 of the humidifying liquid delivery body can also play a good role in guiding the oxygen flow, preventing the oxygen flow from directly entering the humidifying cavity 150 without pre-contacting the water vapor in the through cavity 1500 and the inner cavity 160 of the humidifying liquid delivery body.

[0063] In this example, to increase the humidification area provided by the humidifying liquid delivery body 16, a columnar body 163 is placed in the inner cavity 160 of the humidifying liquid delivery body. The columnar body 163 is made of a material with the ability to adsorb, permeate, and transport the humidifying liquid. The cross-section is in a cross shape to facilitate the flow guiding and humidification. The cross-section of the columnar body 163 can also be selected in any other shape.

[0064] Figure 7B Another structure is shown. An elongated insert 164 with the ability to adsorb, permeate the humidifying liquid 0, and transport the humidifying liquid 0. The lower part 164b of the insert 164 is located in the inner cavity 160 of the humidifying liquid delivery body, and the upper part 164a of the insert 164 penetrates into the inner cavity 130 of the oxygen delivery body. The shape of the insert 164 can be rod-shaped, tubular, spiral-shaped, columnar, twisted, strip-shaped with an irregular cross-section, etc. The upper part 164a of the insert 164 that penetrates into the inner cavity 130 of the oxygen delivery body and adsorbs the humidifying liquid starts the oxygen humidification before the oxygen flow enters the humidifying cavity 150, advancing the oxygen humidification process. The oxygen flow also easily flows downward along the surface of the insert 164, playing a role in guiding the flow, allowing more of the air flow to enter the inner cavity 160 of the humidifying liquid delivery body, mix with the water vapor S initially, and then turn back and flow into each humidifying cavity 150.
