Gas humidification liquid storage container and gas humidification method

The present invention relates to a liquid storage device, and more particularly to a liquid storage container that can be humidified with a high pressure gas supply device and a humidifying method thereof.

Sleep apnea is a common respiratory disorder. During the sleep process, the patient collapses due to the collapse of the airway, causing the airway to block and the air cannot enter the lungs smoothly. This causes the patient to repeatedly stop breathing. The patient with the disease is It is often clinically necessary to use a respiratory therapy device for treatment.

Among the currently known treatment modalities, Continuous Positive Airway Pressure (CPAP) therapy has a significant effect on certain respiratory diseases. In summary, continuous positive pressure therapy uses a blower to provide pressurized air into the respiratory tract through the mask worn by the patient during sleep to prop up the patient's respiratory tract to avoid collapse, allowing the patient to breathe smoothly during sleep. Maintain good sleep quality.

In order to avoid the problem of continuous supply of gas to the respiratory tract and excessive drying of the airway, many respiratory treatment devices are used together with the humidifier to humidify the gas output from the blower before being sent to the patient. Common gas humidification devices are mainly composed of a liquid storage container and a humidifying means (for example, humidification by heating evaporation or ultrasonic atomization). For example, a heating plate may be installed at the bottom of the liquid storage container to heat the liquid in the container to generate steam. The high pressure gas enters the humidifying chamber from the inlet of the liquid storage container and travels along a defined circulation path inside the liquid storage container. It is humidified, then exits from the outlet of the reservoir and sequentially passes through the hose and breathing mask into the patient's respiratory tract.

Although various types of humidifying devices exist on the market, their use is still unsatisfactory, especially in the design of liquid storage containers, there are still many problems to be solved, such as poor humidification efficiency.

It is to be understood that the foregoing general description and the claims

The embodiments are described with reference to the accompanying drawings to improve the understanding of the theory presented herein. Since the various aspects and embodiments are merely illustrative and not restrictive, it will be apparent to those skilled in the The features and advantages of the embodiments will be more apparent from the detailed description and appended claims.

In the present invention, "a" or "an" is used to describe the elements and components described herein. This is done for convenience of description only and provides a general meaning to the scope of the invention. Therefore, unless expressly stated otherwise, this description should be understood to include one or at least one, and the singular also includes the plural. In addition, in this document, the terms "including", "including", "having", "containing" or any other similar terms are intended to cover non-exclusive inclusions. For example, an element, structure, article, or device that comprises a plurality of elements is not limited to such elements as listed herein, but may include those not specifically listed but which are generally inherent in the element, structure, article, or device. Other requirements.

As shown in FIG. 1 to FIG. 3, an exemplary embodiment of the present invention provides a liquid humidifying liquid storage container 1 which can be used for humidifying a gas to increase the humidity of the gas, wherein the gas can include, for example, air, pure. Gas or mixed gas, and the humidification method may be by heat evaporation or ultrasonic atomization, and is not limited thereto.

The gas humidifying liquid storage container 1 mainly includes a first lid body 10, a second lid body 20, a stopper 30, and an exhaust structure 40, which are described below.

Referring to FIG. 4 and FIG. 5 simultaneously, the first cover 10 is mainly used to define a gas circulation path. The first cover 10 is provided with an air inlet 11 which can be connected to a high-pressure gas supply device (such as a blower) for receiving high-pressure gas to be humidified. The first cover 10 has a first portion 13 adjacent to the air inlet 11 and a second portion 15 remote from the air inlet 11. When the gas enters the gas humidifying liquid storage container 1 via the air inlet 11, the gas It will be guided by the curved curved surface inside the first portion 13 and moved toward the second portion 15. In the case where the second cover 20 contains a liquid, the gas moves from the first space S1 defined by the first portion 13 and the blocking member 30 to the second portion S2 defined by the second portion 15 and the blocking member 30. During the movement, the gas is guided by the first guiding structure 131 of the first portion 13 (such as the curved surface on the inner side) to move toward the liquid receiving space LS, and impacts the second cover 20 downward. The liquid contained therein generates physical vaporization, and thus it is advantageous to increase the humidity in the liquid storage container 1 for gas humidification. In addition, since the blocking member 30 is disposed between the first space S1 and the second space S2, when the gas enters the second space S2 from the first space S1, it is first narrowed by the blocking member 30 and the liquid surface. space. At this point, the liquid will pass through the region between the blocking member 30 and the liquid surface at a relatively fast flow rate (flow rate = cross-sectional area * flow rate, Q = AV under the same fluid density), which helps to disturb the liquid surface. The physical vaporization action shortens the time during which the gas stagnates in the gas storage container 1 for gas humidification, thereby improving the humidification efficiency of the gas. Then, the gas passes through the blocking member 30 and enters the second space S2 defined by the second portion 15 and the blocking member 30.

Due to the structural design of the first portion 13, the blocking member 30 and the second portion 15, the moisture generated by the heating plate or other humidifying means, and the moisture generated by the aforementioned physical vaporization, mainly exist in the second space. Within S2, therefore, the humidity of the second space S2 will be greater than the first space S1. This design helps the high pressure gas to quickly pass through the low humidity region (ie, the first space S1 and the narrower region between the blocking member 30 and the liquid surface), shortening the gas residence time, and then in the second space S2 of high humidity. With a large amount of moisture leaving, it has the advantage of greatly improving the humidification efficiency. After passing through the blocking member 30, the high-pressure gas is guided by the second guiding structure 151 of the second portion 15 (such as the curved surface on the inner side), moving away from the liquid receiving space LS, for example toward the second portion 15. The direction of the top flows. When moving in a direction defined by the curved curved surface inside the second portion 15, the gas can enter the exhaust structure 40 toward the first opening 41 in the second space S2 while being mixed with the moisture, thereby leaving the gas humidification. The reservoir 1 is delivered to the patient's respiratory tract.

In one embodiment, the first cover 10 has a structure that is arched on both sides and slightly recessed in the middle, as shown in FIG. The arched portions on both sides have substantially the same shape as the first guiding structure 131 and the second guiding structure 151, respectively, both of which have a substantially inverted U-shaped cross-sectional structure, and the height of the section gradually decreases away from the air inlet 11 Shrink. Therefore, when the gas enters the first cover 10 from the air inlet 11, the gas travels forward along the long axis direction of the first guiding structure 131, and moves downward according to the curved structure gradually moving in the course of traveling. After passing through the blocking member 30, the gas will be guided by the second guiding structure 151, on the one hand, gently changing direction and moving upward, on the one hand, moving from a position with a lower height in the inverted U-shaped cross-sectional structure toward a position having a higher height. When the gas reaches the top of the second guiding structure 151, its traveling direction is gradually reversed and changes downward, so that it can smoothly enter the exhaust structure 40 and leave the gas humidifying liquid storage container 1. With such a structural design, the gas can travel along a smooth path defined by the two guiding structures 131, 151, and after entering the air inlet 11, straight forward in the direction away from the air inlet 11, being guided by the first guide The structure 131 changes direction and moves toward the second portion 15 in the direction of the second cover 20, is guided by the second guiding structure 151 to gradually change direction, moves up to the top of the second guiding structure 151, and then goes down. Exhaust structure 40. With the structural design of the upper cover, a smooth curved gas flow path can be formed without excessively complicated flow channel structure design, so as to effectively achieve high efficiency (ie, short time and high humidity) and low noise gas addition. Wet purpose.

As shown in FIG. 1, the second cover 20 can be coupled to the first cover 10. The connection between the two can be achieved by an integral forming means or by a connection structure. For example, a buttonhole is formed on the first cover 10 and a bump is correspondingly formed on the second cover 20 to fasten the first cover 10 to the second cover 20. The primary use of the second cover 20 defines a liquid containment space LS for containing a liquid to be humidified, such as water, physiological saline or other liquid to which a medicament is added. The bottom of the second cover 20 can be provided with a heating plate as a vaporization means for heating the liquid contained in the second cover 20 to generate moisture when the machine is actuated. In one embodiment, the first cover body 10 and the second cover body 20 are respectively an upper cover and a lower cover, and the two are assembled to form a gas humidification liquid storage container 1, and the air inlet 11 of the upper cover is used as a high pressure gas to enter the liquid storage. The inlet of the container 1 and the lower cover are formed with an air outlet connected to the breathing mask through a hose. The lower cover can be made by integrally forming a heat-resistant plastic material, and the thickness of the bottom portion can be larger than other portions, so that the heating plate can directly heat the bottom portion when the machine is actuated.

A blocking member 30 is further disposed in the cavity space defined by the first cover 10 and the second cover 20 as a barrier when the gas moves from the first portion 13 of the first cover 10 to the second portion 15 and The space defined by the first cover 10 is divided into two main areas. The first portion 13 and the blocking member 30 define a first space S1, and the second portion 15 and the blocking member 30 define a second space S2.

The blocking member 30 may be a structure in which the inner side of the first cover 10 is convex or extended downward, or a separate member disposed between the first cover 10 and the second cover 20. By the arrangement of the blocking member 30, when the high pressure gas enters the first space S1 from the air inlet 11 and moves to the second space S2, the gas movement is hindered and cannot be directly separated by the exhaust structure 40, thereby preventing the gas from humidifying. Full question. Referring to Figures 6 and 7, in the operating state, the gas system is introduced into the first space S1 (low humidity) by the air inlet 11, moves along the curved surface inside the first portion 13, and passes between the blocking member 30 and the liquid surface. The narrow space reaches the second space S2 (high humidity), and the moisture is mixed while moving along the curved surface inside the second portion 15 and then leaves the gas humidifying liquid storage container 1 from the exhaust structure 40.

As shown in FIG. 1 and FIG. 6 , in an embodiment, a partition plate 50 is disposed between the first cover 10 and the second cover 20 , and the partition plate 50 may have a second blocking structure 51 for The first blocking structure 17 of the first cover 10 collectively defines the blocking member 30.

In order to ensure airtightness after assembly, the gasket 80 may be sleeved on the upper and lower sides of the partition plate 50, and grooves may be provided on the first cover 10 and/or the second cover 20. For example, the arrangement of the gasket 80 can increase the friction between the partitioning plate 50 and the second cover 20, so that when the user opens the first cover 10 to add liquid to the liquid accommodating space LS, separation can be avoided. The plate 50 and the second cover 20 are separated from each other.

The exhaust structure 40 is a gas communication structure having a first opening 41 and a second opening 43 communicating therebetween, and a gas passage is defined between the two openings for guiding the humidified gas to the gas storage container for humidifying the gas 1 . As shown in FIG. 1 , for example, the exhaust structure 40 may be a tube body, a portion of which extends vertically upward from the vicinity of the bottom of the second cover 20 so that the first opening 41 is located higher than the second cover 20 . The second space S2 extends in the second space S2, and the other portion extends horizontally from the vicinity of the bottom of the second cover 20 so that the second opening 43 is located outside the second cover 20. The exhaust structure 40 can be integrally formed with the second cover 20, but is not limited thereto.

In one embodiment, the exhaust structure 40 is an L-shaped exhaust pipe, and the first opening 41 and the second opening 43 are respectively located at two ends of the L-shaped exhaust pipe, wherein the first opening 41 is an upward opening (ie, The opening faces the first cover 10), is positioned higher than the second cover 20 and slightly lower than the first cover 10, and is located in the second space S2 defined by the second portion 15 of the first cover 10. Accordingly, after being guided by the second guiding structure 151 in the second space S2, the gas will gradually move upward to the vicinity of the top end of the second portion 15 and change direction and enter the exhaust structure 40 downward through the first opening 41.

As shown in FIG. 6 and FIG. 7 , in an embodiment, the circumference of the first opening 41 of the exhaust structure 40 has a curvature corresponding to the second portion 15 of the first cover 10 , for example, the first opening 41 can be The circumference is designed to be curved or curved, such that the longitudinal distance of each point of the circumference of the first opening 41 to the second portion 15 of the first cover 10 is equal, and the humidified gas around the first opening 41 is uniform The ground enters the exhaust structure 40 without entering only by one side or a portion of the first opening 41. In other words, maintaining the same vertical height of the curved surface of the first opening 41 and the second portion 15 can facilitate the passage of the humidified gas in the second space S2 into the exhaust structure 40 via the first opening 41 with a stable flow rate and humidity. Not only the stability of the airflow in the second space S2 but also the uniform humidity distribution in the second space S2 can be maintained.

By the design that the air inlet 11 is above and the air outlet (second opening 43) is lower, when the liquid humidifying liquid storage container 1 is placed at a position higher than or equal to the user's lying position, the reduction can be reduced. The connection hose between the liquid storage container 1 and the breathing mask is bent. This design will avoid the problem that the conventional liquid storage container with the air outlet on the upper part of the liquid container is not bent smoothly due to the downward bending of the hose or the hose is easily damaged. In addition, as shown in FIG. 1 and FIG. 2, an adapter tube 60 may be additionally disposed at the second opening 43 of the exhaust structure 40, and is rotatably sleeved on the second opening 43 for the user to adjust the storage. The direction of the gas outlet of the liquid container 1 can also reduce the occurrence of gas supply problems.

In order to make the user more convenient to operate at night, the first cover 10 and/or the second cover 20 can form the identification structures 12 and 22, for example, a bump, a groove or the like having an indicating function, which is convenient for the user. Each element or structure of the liquid storage container 1 for gas humidification is perceived by touch. In addition, the identification structures 12, 22 may also be Braille signs or bump structures with special arrangement meanings to meet the needs of different users in use.

Referring to Figures 6 and 7, the gas humidifying liquid storage container 1 can be combined with the main unit 2 (which can include a blower and a heating plate unit) to perform gas humidification. In order to ensure that the two can be firmly combined, a corresponding fastening structure can be respectively disposed on the liquid storage container 1 and the main body 2. In addition, the host 2 can have a magnetic sensor. When the magnetic component disposed on the liquid storage container 1 approaches, the magnetic sensor transmits a signal to the control unit to unlock, and the host 2 can be operated at this time. The danger of the host 2 due to false triggering can be avoided.

In the operating state, the heating plate provided on the main body 2 heats the bottom of the second cover 20 to evaporate the liquid contained in the liquid accommodating space LS, and increases the inner cavity of the first cover 10 and the second cover 20 The humidity of the body space. The high-pressure gas outputted from the main unit 2 enters the gas-humidifying liquid storage container 1 from the air inlet 11 and reaches the first space S1, which is a low-humidity space. In the first space S1, the gas is changed by the action of the first guiding structure 131 to change the traveling direction, and moves away from the air inlet 11 and gradually moves downward and toward the second space S2. By the arc surface design of the first guiding structure 131, the high pressure gas can impact the liquid surface at a relatively high speed, which not only facilitates the formation of vapor of the liquid, but also increases the humidity of the gas in the process. Then, the gas passes through the narrow area between the blocking member 30 and the liquid surface along the arc surface between the first portion 13 and the second portion 15 at a relatively fast speed and thus disturbs the liquid surface, not only shortening the gas in the liquid storage container 1 The internal stagnant time also produces physical vaporization to facilitate gas humidification. After passing through the blocking member 30, the gas enters the second space S2 away from the air inlet 11, which is a high humidity space.

In the second space S2, the gas is guided by the arcuate design of the second guiding structure 151 to travel away from the liquid surface, while a large amount of moisture in the second space S2 is gradually moved toward the top of the second portion 15. . Since the second portion 15 has an inverted U-shaped structure similar to the first portion 13, when reaching the top end, the gas turns and travels downward, entering the exhaust structure from the first opening 41 of the exhaust structure 40 located in the second space S2. 40, and is separated from the gas humidification reservoir 1 by the second opening 43 of the exhaust structure 40 and sent to the patient's respiratory tract.

According to this, in the operating state, the gas entering the gas humidifying liquid storage container 1 from the air inlet 11 is changed in the first direction in the first space S1 of the low humidity, and proceeds toward the liquid surface at a higher flow rate. And passing through the blocking member 30 to the second space S2 at a higher flow rate, then performing the second direction change to pass through the high humidity environment and being effectively humidified in the process, and then performing the third direction change to enter the exhaust structure. 40. Accordingly, the present invention can utilize the first cover 10, the second cover 20, the blocking member 30, and the exhaust structure 40 which are relatively simplified in structure without using an excessively complicated baffle or the like. High humidification efficiency (the overall gas flow path is short, and the flow rate of gas in a low humidity space is fast) and the main purpose of high humidity gas (the gas is repeatedly turned and moved back and forth in a high humidity space).

As described above, in the present invention, each element or structure may be separately formed and assembled, or integrally formed. For example, any portion of the reservoir or humidification device can be fabricated using a suitable mold using extrusion forming, injection molding, or other forming means contemplated by those of ordinary skill in the art. Further, the aforementioned liquid storage container or humidifying device may be formed of various materials, such as various types of plastics, and may be formed of materials conforming to specific medical device regulations.
