Due to the poor thermal insulation performance of the traditional humidification tank, when the external ambient temperature is low, the humidification tank will rapidly exchange heat and cold with the outside world. , the higher the power consumption of the humidifier. Then, as long as the insulation performance of the humidification tank can be improved, this situation can be improved. It should be noted that the present invention does not need to completely isolate the cold and heat exchange between the humidification tank and the outside world, as long as the heat preservation performance of the humidification tank can be improved, the purpose of reducing the power consumption of the humidifier can be achieved.

Based on the above-mentioned ideas, the present invention provides a humidification tank. Compared with the traditional humidification tank, the thermal insulation performance of the humidification tank provided by the present invention has been improved. The humidification tank includes: a tank body 100 (such as 1) and an insulation layer, the insulation layer is used to reduce the speed of heat and cold exchange between the liquid in the tank 100 and the outside world.

As for the thermal insulation layer, a plurality of thermal insulation layers may also be provided inside the tank body 100 and outside the tank body 100, respectively, and the position states refer to the first two cases. In addition, the thermal insulation layer can also be embedded in the tank wall of the tank body; one is that the thermal insulation layer is sandwiched in the wall of the tank body, and the thermal insulation layer is in contact with the wall of the tank body; the other is that the wall of the tank body is double The insulation layer is arranged between the two walls of the tank body, and the insulation layer and the wall of the tank body are not in contact.

It should be noted that when the thermal insulation layer is disposed in the tank body 100, in order to avoid the thermal insulation layer from affecting the liquid in the tank body 100, preferably, the thermal insulation layer is made of a hydrophobic material. Alternatively, when the thermal insulation layer is made of a non-hydrophobic material, it is preferable that the surface of the thermal insulation layer is coated with a hydrophobic material.

One or more thermal insulation layers may be provided. When a plurality of thermal insulation layers are provided, the plurality of thermal insulation layers may be respectively arranged on the inner and outer sides of the tank body, or may be arranged on the same side of the tank body. When a plurality of thermal insulation layers are arranged on the same side of the tank body, two adjacent thermal insulation layers may be attached or separated. In the case of separation, the space between two adjacent insulating layers may be filled with fluid or solid.

There are many types of thermal insulation layers. For example, the thermal insulation layer may be a thermal insulation coating applied to the inner wall and/or outer wall of the tank body 100, or a flexible insulation member ( Such as thermal insulation hoses, thermal insulation silicone sleeves, etc.), or solids located inside and/or outside the tank body 100 (the shape is not limited to a circular ring), etc., which cannot be listed one by one in the present invention.

Preferably, the thermal insulation layer is made of a transparent material or a translucent material; or the thermal insulation layer is made of an opaque material, and there is a gap for observing the liquid level (a transparent material can be installed at the gap). or an observation window made of translucent material); so that the user can observe the water level.

In a specific implementation, the thermal insulation layer 200 is provided inside the tank body 100, as shown in FIG. 1, and the thermal insulation layer 200 is provided with a thermal insulation body 210 made of a transparent material or a translucent material closed around it, as shown in FIG. 2 shown. One is to ensure that the volume maintained by the tank body 100 and the connection method between the humidification tank and the humidifier remain unchanged, which reduces the difficulty of design; the other is to reduce the heat radiated from the periphery of the tank body 100 to the outside as much as possible to improve the thermal insulation performance of the humidification tank; Three are convenient for users to observe the liquid level.

As an improvement of the above-mentioned specific embodiment, the thermal insulation layer 200 is a solid inside the tank body 100, so as to simplify the difficulty of manufacture and installation. Further, a gap is reserved between the thermal insulation layer 200 and the tank body 100 to further improve the thermal insulation performance of the tank body 100 (if the thermal insulation layer 200 is in close contact with the tank body 100, the thermal insulation layer 200 transfers heat to The tank body 100, so that the rate of heat and cold exchange between the tank body 100 and the outside world will be accelerated to a certain extent, affecting the thermal insulation performance).

Preferably, the lower end of the thermal insulation body 210 is open, and the lower end surface is in contact with the heat conduction chassis 300 of the humidification tank. The abutment can be understood as a sealed connection between the lower end of the thermal insulation body 210 and the thermal conduction chassis 300, or a set of Separable non-sealed connections. The heat-conducting chassis 300 (as shown in FIG. 1 ) directly heats the water stored in the heat-insulating body 210 . At the same time, the heat generated by the heat-conducting chassis 300 is directly transferred to the heat-insulating body 210, thereby increasing the temperature of the heat-insulating body 210 and improving the heat-insulating effect.

Or the lower end opening of the heat insulating body 210 is covered with a heat conducting cover (preferably made of metal material, which can be detachable or integrally formed with the heat insulating body), and the heat conducting cover is attached to the heat conducting chassis 300 of the humidification tank; At this time, the heat-insulating body 210 and the heat-conducting cover form a water storage cavity, and the heat-conducting chassis 300 first conducts heat to the heat-conducting cover, and heats the water in the water-storing cavity through the heat-conducting cover.

Further, the heat insulating layer 200 further includes a heat conducting member (not marked in the figure), the heat conducting member is arranged on the inner wall and/or the outer wall of the heat insulating body 210, or is embedded in the heat insulating body 210, and the heat conducting member is The lower end abuts against the heat-conducting cover or the heat-conducting chassis 300 . While the heat-conducting cover or the heat-conducting chassis 300 heats the water, the heat is also conducted to the heat-conducting member, and the heat is transferred to the heat-insulating body through the heat-conducting member, thereby further improving the heat-insulating effect of the heat-insulating body. When the heat-conducting member is embedded inside the heat-insulating body 210, it can not only achieve heat-preservation effect, but also avoid oxidation of the heat-conducting member, and at the same time make the heat-insulating body more uniformly heated inside and outside (reflected in the temperature difference between the inner wall and the outer wall of the heat-insulating body).

It is easy to understand that the present invention does not need to specifically limit the shape of the heat-conducting member, whether it is a heat-conducting column, a heat-conducting wire, a heat-conducting net or a component with a heat-conducting function, it can achieve the purpose of conducting heat.

Further, when the heat insulating body 210 is arranged in the tank body: the upper end of the tank body 100 is provided with an air inlet pipe, and the air inlet pipe can extend to the inside of the tank body 100 or to the outside of the tank body 100 . The tank body 100 is provided with an air outlet pipe at the upper end, and the air outlet pipe can extend to the inside of the tank body 100 or to the outside of the tank body 100 . The heat preservation body 210 is closed all around, the upper end of the heat preservation body 210 is provided with an air inlet and an air outlet, and the rest of the area is closed.

The air inlet of the insulation body 210 is in fluid communication with the air inlet pipe of the tank body 100 . The periphery of the air port, or the air inlet of the heat insulating body 210 is communicated with the air inlet pipe of the tank body 100 through a pipeline, and the like. Similarly, the air outlet of the thermal insulation body 210 is in fluid communication with the outlet pipe of the tank body 100 . The fluid communication may be that the outlet pipe of the tank body 100 is inserted into the air outlet of the thermal insulation body 210 , or the outlet pipe of the tank body 100 is connected to the outlet of the thermal insulation body 210 . The periphery of the air port, or the air outlet of the heat insulating body 210 is communicated with the air outlet pipe of the tank body 100 through a pipeline, and the like.

Preferably, an air intake pipe extends outward (or inward) from the tank body 100 , and an air intake short pipe 220 extends outward from the air inlet of the thermal insulation body 210 , as shown in FIG. 2 , and the intake The upper end of the short gas pipe 220 is built in the air inlet pipe; similarly, the tank body 100 extends outward (or inward) with an air outlet pipe; the air outlet of the thermal insulation body 210 extends outward with a short gas outlet pipe 230, As shown in FIG. 2 , the upper end of the short air outlet pipe 230 is built into the air outlet pipe.

Alternatively, the tank body 100 extends inwardly with an air intake pipe, the thermal insulation body 210 extends outward (or inwardly) with an air intake short pipe 220, and the air intake pipe is built in the air intake short pipe 220; Similarly, the tank body 100 extends inward with an air outlet pipe; the thermal insulation body 210 extends outward (or inwardly) with a short air outlet pipe 230. As shown in FIG. 2 , the air outlet pipe is built in the air outlet short pipe. inside tube 230.

From the above, the short air inlet pipe and the short gas outlet pipe on the thermal insulation body 210 are used to cooperate with the tank body 100 , so as to fix the thermal insulation main body 210 simply and conveniently, while preventing the gas flow from being affected.

In addition, when the upper and lower ends are open relative to the heat preservation body, the gas delivered by the humidifier (or the respiratory therapy device integrating the functions of the humidifier and the ventilator) will be discharged into the tank 100 ( That is, part of the gas will enter the interior of the insulation layer, and the other part of the gas will enter between the insulation body and the tank body 100, so as to exchange cold and heat with the outside through the tank body), speed up the exchange of cold and heat between the gas in the humidification tank and the outside world, reduce Insulation effect of humidification tank. For the humidification tank provided with the short inlet pipe and the short gas outlet pipe, the gas entering between the insulation body and the tank body is minimized or even avoided (only the lower end of the insulation body is open, and the opening is heated by heat. When the cover is sealed, the gas (or most of the gas) delivered by the humidifier will only flow through the inlet short pipe, the water storage cavity of the insulation body and the gas outlet short pipe in turn, so that the insulation effect of the humidification tank is further improved. improve.

When the thermal insulation body cover is set outside the tank body, the inlet pipe and the gas outlet pipe of the tank body can also be inserted into the short gas inlet pipe and the short gas outlet pipe of the thermal insulation body respectively, so as to improve the thermal insulation effect (reduce the gas in the gas inlet pipe and the gas outlet pipe). At the same time as the exchange rate of cold and heat with the outside world), the relative position of the heat preservation body and the tank body is fixed.

It is not difficult to see from the above two embodiments that there are still many structures that can achieve similar effects of the above embodiments: for example, the air intake pipe and/or the air outlet pipe of the tank body, and the air intake short pipe and/or the outlet pipe of the thermal insulation body are provided. The short gas pipe is extended inward, and the intake pipe and/or the gas outlet pipe of the tank body is inserted into the short gas inlet pipe and/or the short gas outlet pipe of the thermal insulation body, so as to achieve the purpose of improving the thermal insulation effect and fixing the position of the thermal insulation body; When the body is a thermal insulation jacket wrapped around the outside of the tank, the shape of the thermal insulation body is adapted to the outer wall of the entire tank (including the air inlet pipe and/or the air outlet pipe part), which can also improve the thermal insulation effect and fix the thermal insulation body; the utility model cannot List them one by one and will not repeat them here.

Preferably, the height of the insulation layer 200 is 1/3 to 4/5 of the height of the humidification tank, and the height of the insulation layer 200 is further selected to be 1/3 to 1/2 of the height of the humidification tank. Since the water level in the humidification tank is not too high, the height of the insulation layer has no substantial effect on water storage (as long as a sufficient amount of water can be stored); The low height of the insulation layer can make the gas flowing into the insulation layer closer to the liquid level in the tank, thereby improving the humidification effect of the gas. The reason why the height of the thermal insulation layer 200 in the present invention is preferably 1/3-1/2 of the height of the humidification tank is to ensure that a certain amount of gas can be accommodated in the thermal insulation layer while improving the gas humidification effect.

For example, there are two gas inlets in the body and one gas outlet in the body for explanation. The body has an air inlet a and a high pressure oxygen inlet o, and the gas outlet of the body is connected and in fluid communication with the gas inlet of the humidification tank. The gas outlet of the humidification tank is connected with one end of the breathing circuit, and the other end of the breathing circuit is used by the patient.

The high-pressure oxygen and air flow into the body, and after mixing in the mixing chamber in the body, the mixed gas enters the humidification tank, humidifies the gas, and then provides it to the patient through the breathing circuit. Among them, the humidification tank is provided with a thermal insulation layer, so in a low temperature use environment, the energy consumption of the heating plate is greatly reduced compared to the case where the humidification tank is not provided with an thermal insulation layer.

In the case where the thermal insulation layer is arranged on the outside of the humidification tank, the thermal insulation layer and the body can be fixed, and then a semi-closed or closed space is formed between the insulation layer and the body, and the humidification tank is installed in the space, and furthermore The insulation layer can achieve the insulation of the humidification tank. In this case, openings or short pipes can also be provided on the insulation layer, and the openings and short pipes can pass through the air inlet pipe and the air outlet pipe of the humidification tank, so as to avoid the air inlet and outlet of the humidification tank. It is also worth noting that the arrangement of the thermal insulation layer in this embodiment can also be used in combination with the thermal insulation layer described in any one of the above embodiments. For example, in combination with the above-mentioned embodiment in which the thermal insulation layer is arranged in the humidification tank, it is obtained that the insulation layer is provided inside and outside the humidification tank, thereby greatly improving the thermal insulation effect of the humidification tank.

It should be understood that the application of the present invention is not limited to the above-mentioned examples. For those of ordinary skill in the art, improvements or transformations can be made according to the above descriptions. All these improvements and transformations should belong to the protection of the appended claims of the present invention. scope.
