Description

Distilled water heating device having a detachable coupling structure

[0001] The present invention relates to a distilled water heating device of a respiratory assistance device that heats / humidifies respiratory gas generated from a ventilator and delivers it to a patient, and more particularly, to a distilled water heating device having a detachable coupling structure comprising a chamber portion in which distilled water is stored, and a main body that heats the distilled water stored in the chamber portion.

[0002] In general, surgical patients requiring anesthesia, critically ill patients, or elderly patients who have difficulty breathing on their own are forced to breathe through a ventilator. However, the respiratory gas (anesthetic, oxygen, etc.) supplied to the patient through the ventilator has the problem of causing other side effects because the temperature and humidity are low.

[0003] To elaborate, the respiratory gas inhaled by a patient through a ventilator is not only cold enough to chill the patient, but also dehydrates the patient's airways and lungs due to its dryness. Furthermore, as the respiratory gas supplied from the ventilator condenses within the tube as it passes through it, the water droplets formed within the tube can be directly inhaled into the patient's lungs, potentially causing other health problems, such as dryness, ulcers, mucus plug formation, and mucociliary dysfunction in the patient's bronchial mucosa.

[0004] Currently, respiratory assistance devices are being used to appropriately control the temperature of the respiratory gas supplied from the ventilator to solve the above problems.

[0005] A respiratory assistance device warms and humidifies the respiratory gas generated from a ventilator so that the patient can receive respiratory gas at an appropriate temperature and humidity.

[0006] However, since conventional respiratory assistance devices have a configuration that controls the humidity of respiratory gas by vaporizing distilled water stored in a chamber through ultrasonic vibration, there is a problem that when the respiratory assistance device is used for a long time or, conversely, when it is not used for a long time, the distilled water stored in the chamber becomes contaminated and causes germs or bacteria to occur.

[0007] In addition, there is a problem that the inner surface of the chamber is worn out because the distilled water stored in the chamber repeatedly collides with the inner surface of the chamber in the form of numerous water droplets due to the water splashing phenomenon caused by ultrasonic vibration.

[0008] Therefore, recently, a method of controlling the temperature and humidity of the respiratory gas by heating distilled water stored in the chamber has been used.

[0009] A respiratory assistance device using a heating method is configured to include a main body provided with a heating plate and a chamber detachably connected to the main body, but has a structure that makes it difficult for a user to accurately connect the chamber to a set position of the main body, and also has a problem in that the user has difficulty in determining whether the chamber is accurately connected to the set position of the main body, and thus has to monitor the operating status for a long time.

[0010] Additionally, there is a problem that the user may be burned by the high temperature of the heat-conducting plate provided in the chamber during the process of separating the chamber from the main body.

[0011] Accordingly, the applicant of the present invention proposed the present invention to solve the above-mentioned problems, and a related prior art document is 'Medical automatic temperature and humidity controller with anti-condensation function' of Korean Patent No. 10-1479545.

[0012] The present invention is intended to solve the above-mentioned problems, and the purpose of the present invention is to provide a distilled water heating device having a detachable coupling structure configured to enable a user to easily and accurately couple a water chamber to a set position of the main body.

[0013] The present invention relates to a distilled water heating device comprising: a main body having a heating plate provided at an upper portion thereof; and a chamber portion detachably provided at an upper portion of the main body and storing distilled water therein; wherein a guide frame defining a mounting groove for mounting the chamber portion may be provided at an upper portion of the main body, and limiting forward and backward sliding movement and up and down movement of the chamber portion.

[0014] Additionally, the guide frame may be arranged along a portion of the circumference of the heating plate on the upper portion of the heating plate exposed to the upper surface of the main body.

[0015] Additionally, a side groove that can communicate with the mounting groove may be formed between the bottom surface of the guide frame and the top surface of the main body.

[0016] In addition, the chamber portion may include a water chamber that is seated in the seating groove and stores distilled water; a heat-conducting plate that is provided at the lower portion of the water chamber and is in contact with the heating plate; and a cover that is provided along the circumferential direction of the heat-conducting plate and is detachably connected to the guide frame.

[0017] In addition, the cover may include a first circumferential member provided along the side and rear circumferences of the water chamber and inserted into the side groove to be detachably coupled with the guide frame; and a second circumferential member provided along the front circumference of the water chamber while connected to the first circumferential member, and exposed to the outside of the mounting groove when the first circumferential member is inserted into the side groove.

[0018] Additionally, a step surface that comes into contact with a stopper surface formed on the guide frame may be formed at the connection point between the first circumferential member and the second circumferential member.

[0019] In addition, a fastening protrusion may be formed on the upper surface of the first circumferential member, and a fastening groove into which the fastening protrusion can be inserted may be formed on the lower surface of the guide frame.

[0020] In addition, the heating plate is provided in the main body while being supported by an elastic means provided inside the main body, and can move toward the inside of the main body when an external force is applied by a user to the second circumferential member or the water chamber.

[0021] In addition, a magnetic detection sensor may be provided on the inside of the main body to detect the magnetism of a magnet provided on the bottom surface of the second peripheral member when the first peripheral member is inserted into the side groove, thereby confirming whether the first peripheral member and the guide frame are fastened.

[0022] In addition, when the chamber part is seated in the seating groove, the upper surface of the first circumferential member inserted into the side groove is in close contact with the lower surface of the guide frame that defines the side groove, and the lower surface of the second circumferential member is spaced apart from the upper surface of the main body by a predetermined distance so as to form a state of not contacting the upper surface of the main body.

[0023] A distilled water heating device having a detachable coupling structure according to one embodiment of the present invention has a configuration that allows a user to intuitively feel whether a water chamber is accurately mounted on a set position of the main body and also guides the user with a detection sensor using a magnet, thereby providing convenience in the mounting process to nurses or the elderly, and in particular, enabling heat generated from a heating plate to be transferred intact to a heat conducting plate.

[0024] In addition, a distilled water heating device having a detachable coupling structure according to one embodiment of the present invention can prevent a safety accident of being burned by a heat-conducting plate by using a cover provided around the water chamber during the process of detaching the water chamber mounted on the main body, and allows the user to easily detach the water chamber from the main body with a simple operation.

[0036] For reference, this project is the result of a local government-university collaboration-based regional innovation project (2021RIS-001), funded by the Ministry of Education and supported by the National Research Foundation of Korea in 2024.

[0037] This research was supported by "Regional Innovation Strategy (RIS)" through the National Research Foundation of Korea(NRF) funded by the Ministry of Education(MOE)(2021RIS-001)

[0038] First, the distilled water heating device (100) having a detachable coupling structure according to one embodiment of the present invention can be said to be a component through which respiratory gas generated from an artificial respirator (1) passes, as illustrated in FIG. 1. For reference, the respiratory gas passing through the distilled water heating device (100) can be delivered to a patient through a circuit unit (SC) constituting a respiratory assistance device (10).

[0039] As illustrated in FIGS. 2 to 7, a distilled water heating device (100) according to one embodiment of the present invention may include a main body (200) having a heating plate (210) provided on the upper portion; and a chamber portion (300) detachably provided on the upper portion of the main body (200) and having distilled water stored therein.

[0040] The above main body (200) preferably has a shape that can be stably placed on the floor surface, as shown in FIGS. 4 and 5, and is preferably manufactured with a weight and volume that allows the user to easily carry and store it.

[0041] On the front upper surface of the main body (200), various control buttons including a power button may be provided, and a display may also be provided to display to the user the temperature, alarm, various status modes, etc. of the circuit unit (SC) shown in FIG. 1.

[0042] Inside the main body (200), a known PCB that is connected to various control buttons and controls the heating plate (210) and display, etc. may be provided.

[0043] In addition, the upper surface of the heating plate (210) may be placed on the rear side of the upper surface of the main body (200). That is, the upper surface of the heating plate (210) is exposed to the outside from the upper surface of the main body (200) and may be in surface contact with the lower surface of the chamber portion (300) described later.

[0044] In addition, a guide frame (220) may be provided on the upper rear surface of the main body (200) to simultaneously define a mounting groove (S1) in which a chamber part (300) to be described later is mounted, and a side groove (S2) to prevent the chamber part (300) mounted on the main body (200) from moving.

[0045] The guide frame (220) may be formed to protrude from the upper edge of the main body (200) at a predetermined height so that the upper surface of the heating plate (210) can be exposed to the outside. For reference, the guide frame (220) may have a 'ㄷ' shaped plane when the main body (200) is viewed from a flat surface.

[0046] Additionally, the upper portion of the inner surface of the guide frame (220) may be formed to protrude a predetermined length toward the direction in which the heating plate (210) is placed.

[0047] Accordingly, a side groove (S2) in which a cover (330) of a chamber portion (300) to be described later is mounted can be formed between the inner surface of the guide frame (220) and the upper surface of the main body (200).

[0048] In detail, the guide frame (220) can define a mounting groove (S1) on the upper surface of the main body (200) in which the chamber part (300) can be mounted, and at the same time define a side groove (S1) that is formed along the circumference of the mounting groove (S1) and is connected to the mounting groove (S1) so as to be communicable with the mounting groove (S1).

[0049] Meanwhile, the heating plate (210) may be provided in the main body (200) while being supported by an elastic means (not shown) provided inside the main body (200).

[0050] That is, the lower portion of the heating plate (210) can be supported by a known elastic means (not shown), such as an elastic spring. Accordingly, when an external force is applied to the upper surface of the heating plate (210), it can move toward the inside of the main body (200).

[0051] The above heating plate (210) can elastically press upward the bottom surface of the chamber part (300) when the chamber part (300) is seated in the seating groove (S1) of the main body (200).

[0052] In detail, when the chamber part (300) to be described later is seated in the seat groove (S1), the heating plate (210) is supported by an elastic means and presses the bottom surface of the heat-conducting plate (320, see FIG. 7) constituting the chamber part (300) with a predetermined pressure.

[0053] Then, the heating plate (210) and the heat conducting plate (320, see Fig. 7) can be in close contact with each other. Accordingly, the heat generated from the heating plate (210) can be completely transferred to the heat conducting plate (320, see Fig. 7).

[0054] In addition, since the heating plate (210) presses upward the bottom surface of the heat conduction plate (320, see FIG. 7) at a predetermined pressure, the upper surface of the first peripheral member (331, see FIG. 6) constituting the chamber portion (300) is in close contact with the bottom surface of the guide frame (220), thereby further preventing the flow of the chamber portion (300).

[0055]

[0056] The chamber part (300) may include, as shown in FIGS. 6 and 7, a water chamber (310) that is seated in the seating groove (S1) and stores distilled water; a heat-conducting plate (320) provided at the lower portion of the water chamber (310) and in contact with the heating plate (210); and a cover (330) provided along the circumferential direction of the heat-conducting plate (320) and detachably coupled to the guide frame (220).

[0057] The above water chamber (310) forms an internal space in which distilled water can be stored.

[0058] At the center of the upper surface of the water chamber (310), a distilled water supply port (311) connected to a tube (see Fig. 1) that delivers distilled water can be formed.

[0059] The above distilled water supply port (311) can be connected to a distilled water supply pipe (not shown) placed inside the water chamber (310).

[0060] In addition, a respiratory gas discharge port (312) that is communicatively connected to the suction tube of the circuit unit (SC) may be formed on one side of the upper surface of the water chamber (310), and an air inlet port (313) that is communicatively connected to the air tube (1a) connected to the artificial respirator (10) may be formed on the other side of the upper surface of the water chamber (310), as shown in FIG. 1.

[0061] It is preferable that the water chamber (310) configured as described above be made of a transparent material so that the user can easily check the internal space with the naked eye.

[0062]

[0063] The above heat conduction plate (320) serves to block the open lower part of the water chamber (310) while simultaneously heating the distilled water stored in the internal space of the water chamber (310).

[0064] The heat conducting plate (320) is in contact with the heating plate (210) exposed to the upper surface of the main body (200), and can heat the water inside the water chamber (310) by receiving heat generated from the heating plate (210).

[0065] The heat conducting plate (320) can be made of a known metal material with excellent heat conductivity, and in particular, it is preferable to make it of stainless steel, which is light in weight but has excellent corrosion resistance and durability.

[0066] For reference, a heat-conducting plate (320) made of stainless steel can provide excellent heat conductivity and durability even when manufactured with a relatively small thickness compared to a heat-conducting plate made of aluminum, and can also reduce the overall weight of the chamber portion (300).

[0067]

[0068] The above cover (330) is provided along the circumference of the heat-conducting plate (320) while being coupled to the lower circumference of the water chamber (310), and can be said to be a component that is detachably coupled to the guide frame (220) while being inserted into the side groove (S2) partitioned by the guide frame (220).

[0069] The cover (330) can be considered a component that is held by the user when moving the water chamber (310) and the heat conduction plate (320). In addition, the cover (330) can be made of a plastic material with low thermal conductivity.

[0070] Therefore, the user can safely move the water chamber (310) without being burned by the high-temperature heat-conducting plate (320).

[0071] The above cover (330) is described in more detail as follows.

[0072] As illustrated in FIGS. 6 and 7, the cover (330) may include a first circumferential member (331) provided along the side and rear circumferences of the water chamber (310) and inserted into the side groove (S2) to be detachably coupled with the guide frame (220); and a second circumferential member (332) provided along the front circumference of the water chamber (310) while connected to the first circumferential member (331), and exposed to the outside of the mounting groove (S1) when the first circumferential member (331) is inserted into the side groove (S2).

[0073] The first peripheral member (331) constituting the cover (330) may have a shape corresponding to the shape of the side groove (S2) partitioned by the guide frame (220).

[0074] In one embodiment of the present invention, as the side groove (S2) is formed in a 'ㄷ' shape, the first peripheral member (331) is also shown in the drawing to have a 'ㄷ' shape.

[0075] The upper surface of the first circumferential member (331) can be in contact with the lower surface of the guide frame (220).

[0076] Accordingly, when the first circumferential member (331) is inserted into the side groove (S2), the sliding movement in a straight direction can be restricted by the closed inner surface of the guide frame (220), and further, the movement in the up / down direction can be restricted by the bottom surface of the guide frame (220).

[0077] As illustrated in FIG. 2, the second circumferential member (332) can be said to be a component that is exposed to the outside of the mounting groove (S1) when the first circumferential member (331) is inserted into the side groove (S2).

[0078] Meanwhile, as illustrated in FIG. 6, a step surface (333) may be formed at the connection point between the first peripheral member (331) and the second peripheral member (332).

[0079] The above step surface (333) is formed by the height difference between the first peripheral member (331) and the second peripheral member (332), and can be in contact with the stopper surface (221) of the guide frame (220) illustrated in FIGS. 3 and 4.

[0080] The above step surface (333) and the above stopper surface (221) can come into contact with each other when the first peripheral member (331) slides a set distance while being inserted into the side groove (S2).

[0081] Accordingly, the step surface (333) and the stopper surface (221) serve to intuitively guide the user so that the chamber part (300) can slide and move by a set distance. That is, the user can easily confirm that the chamber part (300) has moved by the set distance by feeling the step surface (333) and the stopper surface (221) contact each other.

[0082] Additionally, as illustrated in FIG. 6, a fastening protrusion (331a) may be formed protruding on the upper surface of the first peripheral member (331).

[0083] The fastening projection (331a) formed on the first circumferential member (331) can be inserted into the fastening groove (not shown) formed on the bottom surface of the guide frame (220) when the step surface (333) and the stopper surface (221) come into contact with each other as the first circumferential member (331) is inserted into the side groove (S2).

[0084] Accordingly, the movement of the chamber part (300) mounted on the upper part of the main body (200) can be further prevented by the mutual coupling of the fastening projection (331a) and the fastening groove (not shown).

[0085] For reference, in one embodiment of the present invention, it has been described that a fastening projection (331a) is formed to protrude from the upper surface of the first peripheral member (331), and a fastening groove (not shown) is formed on the lower surface of the guide frame (220) to be coupled with the fastening projection (331), but this is not limited thereto. For example, a fastening projection may be formed to protrude downward from the lower surface of the guide frame (220), and a fastening groove may be formed on the upper surface of the first peripheral member (331).

[0086] Meanwhile, as illustrated in FIG. 7, a magnet (332a) may be provided on the bottom surface of the second peripheral member (332).

[0087] The above magnet (332a) can be said to be a component detected by a magnetic detection sensor (250, see FIG. 5) provided inside the main body (200).

[0088] In detail, when the first peripheral member (331) of the cover (330) is inserted into the side groove (S2) and moved by a set distance, the magnetic detection sensor (250) provided inside the main body (200) detects the magnet (332a) provided on the bottom surface of the second peripheral member (332) and determines whether the chamber part (300) has slid by the set distance and is mounted in the correct position.

[0089] For reference, the detection signal by the magnetic detection sensor (250) can be displayed on a display placed on the front side of the upper surface of the main body (200) and transmitted to the user.

[0090] Therefore, the user can easily check whether the chamber part (300) is correctly mounted on the upper part of the main body (200) based on the signal displayed on the display.

[0091]

[0092] Hereinafter, with reference to FIGS. 2 and 3, a process in which a chamber part (300) configured as described above is coupled to the upper portion of the main body (200) is described as an example.

[0093] First, the user can preferentially insert the first peripheral member (331) of the cover (330) into the mounting groove (S1) and side groove (S2) through the open inlet formed in the upper part of the main body (200) while holding the second peripheral member (332) or water chamber (310) of the cover (330) by hand.

[0094] Next, the user can slide the second peripheral member (332) or the water chamber (310) in the direction of arrow A shown in FIG. 3 to insert the first peripheral member (331) into the side groove (S2). In this process, the lower surface of the heat-conducting plate (320) applies a predetermined pressure to the upper surface of the heating plate (210), and in conjunction with this, the heating plate (210) can be moved into the main body (200) while pressing an elastic means (not shown) provided on the inside of the main body (200).

[0095] When the first peripheral member (331) is inserted into the side groove (S2), the step surface (333) formed on the cover (330) and the stopper surface (221, see FIG. 2) formed on the side frame (220) can come into contact with each other. At this time, the fastening protrusion (331a) formed on the first peripheral member (331) can be inserted into the fastening groove (not shown) formed on the bottom surface of the guide frame (220).

[0096] Then, the user can intuitively feel that the step surface (333) and the stopper surface (221) are in contact with each other, and at the same time, can easily confirm that the chamber part (300) has slid a set distance by hearing the sound of the fastening projection (331a) being fastened when it is inserted into the fastening groove (not shown).

[0097] In addition, when the chamber part (300) is seated in the seating groove (S1), as described above, since the heating plate (210) is pressed by the elastic means (not shown) to press upward the bottom surface of the heat-conducting plate (320), the upper surface of the first peripheral member (331) inserted into the side groove (S2) can be brought into closer contact with the bottom surface of the guide frame (220) that divides the side groove (S2). At this time, the bottom surface of the second peripheral member (332) is spaced apart from the top surface of the main body (200) by a predetermined distance and is in a non-contact state with the top surface of the main body (200).

[0098]

[0099] Hereinafter, the process of separating the chamber part (300) configured as above from the upper part of the main body (200) is described as an example.

[0100] In order to separate the chamber part (300) coupled to the upper part of the main body (200) from the main body (200), the second peripheral member (332) or the water chamber (310) of the cover (330) exposed to the outside of the mounting groove (S1) can be pulled and slid in the direction of arrow B shown in FIG. 3 while being held by hand.

[0101] Then, the fastening projection (331a) can be detached from the fastening groove (not shown) formed on the bottom surface of the guide frame (220).

[0102] Next, the user can slide the second circumferential member (332) or the water chamber (310) in the direction of arrow B shown in Fig. 9 until the bottom surface of the guide frame (220) and the top surface of the first circumferential member (331) do not contact each other.

[0103] When the above state is reached, the chamber part (300) becomes completely detachable from the upper part of the main body (200). At this time, since the heating plate (210) is in a non-contact state with the lower surface of the heat-conducting plate (320), it can be raised upwards by a predetermined distance by being pressed by the elastic means and exposed to the upper surface of the main body (200).

[0104] As another example, the user can first pressurize the upper surface of the second peripheral member (332) exposed to the outside of the mounting groove (S1) by hand and then slide the water chamber (310) in the direction of arrow B shown in FIG. 3.

[0105] When a user presses the upper surface of the second circumferential member (332) with his / her hand, the lower surface of the second circumferential member (332) and the upper surface of the main body (200) come into contact with each other.

[0106] In addition, due to the external force of the user pressing the second peripheral member (332), a portion of the entire portion of the heat-conducting plate (320), that is, a portion of the heat-conducting plate (320) positioned close to the second peripheral member (332), is lowered to pressurize the heating plate (210).

[0107] Additionally, by the external force of the user pressing the second circumferential member (332), a portion of the length of the first circumferential member (331) positioned close to the second circumferential member (332) may also be lowered.

[0108] When the above state is achieved, a portion of the longitudinal direction of the first peripheral member (331) and the bottom surface of the guide frame (220) are in a non-contact state. In addition, the fastening projection (331a) protruding from the above portion and the fastening groove (not shown) formed on the bottom surface of the guide frame (220) can be separated from each other.

[0109] Accordingly, the user can completely separate the chamber portion (300) from the upper portion of the main body (200) by holding the water chamber (310) while pressing the upper surface of the second peripheral member (332) with his / her hand and sliding it in the direction of arrow B shown in FIG. 3. At this time, since the heating plate (210) is in a non-contact state with the lower surface of the heat-conducting plate (320), it can be raised upward by a predetermined distance by being pressed by the elastic means and exposed to the upper surface of the main body (200).

[0110] Although specific embodiments of the present invention have been described so far, it is obvious that various modifications are possible within the scope of the present invention.

[0111] Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the claims described below, but also by equivalents of the claims.

[0112] The present invention can be sold and used in the medical device industry.
