[0031] This disclosure provides a solution heating container, such as a fluid heating system, in which medical solutions, serums, and other fluids can be heated to a preferred temperature. According to some embodiments, the solution heating container includes an internal reservoir defined by an outer wall, in which fluid can be disposed. A heating device may be disposed in the internal reservoir and immersed in the fluid, and may include at least one pair of electrodes operable to heat the fluid when current is supplied to the electrodes and subsequently through the fluid. In various embodiments, power can be supplied to the heating device via direct contact or magnetic induction. The solution heating container may also include a recess into which a compatible charging device can be inserted. The charging device may be configured to supply current directly to the solution heating container via electrical contacts, or may induce current in the solution heating device via magnetic induction.

[0032] Figure 1A A solution heating container 100 is shown, comprising an internal reservoir 112 defined by an outer wall 110, a first electrode 120A, a second electrode 120B (collectively referred to as electrode 120), a first electrical contact 130A, and a second electrical contact 130B (collectively referred to as electrical contact 130). The internal reservoir 112 is defined by the outer wall 110, which further defines a recess 135 in which the electrical contact 130 is disposed. The outer wall 110 may also include a separable portion, such as a cap 150. The internal reservoir 112 is configured to hold a fluid 114. In various embodiments, the fluid 114 may include one or more of a saline solution, a therapeutic agent, blood, or serum.

[0033] According to some embodiments, the outer wall 110 is made of a non-reactive medical-grade material suitable for fluid inclusion. This material may include various rigid plastics, acrylic resins, or other materials with high electrical resistance. In some embodiments, this material includes polyethylene or polypropylene. In some embodiments, polyvinyl chloride is omitted or otherwise excluded from this material. In some embodiments, this material includes plastic-coated or wax-coated paper or cardboard. In some embodiments, this material may be layered or laminated together to form a composite of several such materials, which may be fixed together via wax, epoxy resin, resin, adhesive, etc.

[0034] In various embodiments, the conductive material layer may be completely or partially omitted to ensure that electricity is conducted through contact 130 to electrode 120 without being transmitted to the rest of the system. In various embodiments, partial omission may describe the removal or absence of a conductive layer in recess 135, but included elsewhere in the system. For example, an aluminum layer may have a punched hole corresponding to the location where recess 135 will be formed, such that when assembled with other layers to define outer wall 110, the aluminum layer is partially omitted from recess 135 while being included elsewhere. In various embodiments, partial omission may include omission from the bottom surface, omission from recess 135, omission from a region on the bottom surface including recess 135 and a perimeter of 1 cm around recess 135, etc. In various embodiments, the partially omitted portion of a layer may be replaced by a non-conductive layer corresponding in thickness and cross-sectional shape to the partial omission. In some embodiments, the partial omission may be filled by adjacent layers that mate with each other in the partially omitted region but are separated from each other by conductive layers elsewhere in the container.

[0035] The outer wall 110 is configured to provide rigid support for the container 100, allowing the container 100 to maintain a defined shape (e.g., a rectangular prism) and to position the various components of the container 100 at different heights without relying on an external container or support system. The rigid configuration of the container 100 also allows for the replacement of various bagged medical solution delivery systems. Advantageously, because the shape of the container 100 does not deform during fluid delivery operations (as does a bagged solution delivery system when the amount of fluid therein decreases), the outer wall 110 maintains a consistent position and provides a stable platform from which fluid 114 is dispensed. In various embodiments, the container 100 includes a heating device (e.g., electrode 120) that allows preheating of the fluid 114 prior to delivery or simultaneous heating of the fluid 114 during delivery.

[0036] According to some embodiments, the first electrode 120 A is a phase electrode or anode. In this embodiment, the second electrode 120B is a neutral electrode or cathode. The electrodes 120 are arranged close to each other but not in contact on the inner surface of the internal reservoir 112. Each electrode 120 is associated with a corresponding electrical contact 130; for example, the first electrode 120 A is electrically connected to the first electrical contact 130A, and the second electrode 120 B is electrically connected to the second electrical contact 130B. During operation, the electrodes 120 transmit current via fluid 114 contained within the internal reservoir 112. The current flowing through the fluid 114 between the electrodes 120 produces a heating effect in the fluid 114, and the heating effect is used to heat the fluid 114 to a desired temperature.

[0037] The magnitude of the heating effect on fluid 114 corresponds to the amount of current flowing between electrodes 120 and the duration for which the current is applied; for example, a larger current results in more heat input to fluid 114. According to some embodiments, the solution heating container 100 is capable of heating fluid 114 to temperatures up to 30°C, 31°C, 32°C, 33°C, 34°C, 35°C, 36°C, 37°C, 38°C, 39°C, 40°C, or higher, based on the body temperature of a biological subject. In various embodiments, the magnitude of the current is configured such that the average temperature of fluid 114 in the container does not exceed a target temperature. In various embodiments, the charging device for supplying current to electrodes 120 includes a thermostat or temperature sensor that cuts off the current supply once a threshold temperature is reached.

[0038] The distance between electrodes 120 can correspond to the power capacity of the charging device (see...). Figure 2 , Figure 4 This can further correspond to the fluid volume of the internal reservoir 112. The distance between the electrodes 120 can range from 1 millimeter (mm) to about 100 mm, which can correspond to the fluid volume of the internal reservoir 112 ranging from 100 milliliters (mL) to about 5000 mL. This disclosure also envisions that the distance between the electrodes 120 can be standardized across embodiments of different sizes and volumes.

[0039] In some examples, the solution heating container 100 includes a fluid port 160 capable of facilitating fluid communication inflow and / or outflow from the solution heating container 100. The fluid port 160 may be configured as an inlet or outlet port to fill or dispense fluid 114 from the solution heating container 100. The fluid port 160 may be configured to attach to various devices for fluid transfer purposes, such as tubing, fluid connectors, and valves. In some examples, the fluid port 160 may be configured as a valve. In some examples, the fluid port 160 includes a removable cap for single-use or reusable applications. In some embodiments, the fluid port 160 is configured to receive a therapeutic agent for delivery to a biological subject, co-delivered with fluid 114 held in an internal reservoir 112.

[0040] In some examples, the electrode 120 is preferably positioned relative to the solution heating container 100 on the “bottom” surface of the inner reservoir 112 during operation. By positioning the heating device on the “bottom” of the solution heating container 100 in the desired orientation during operation, the heat generated in the fluid 114 between the electrodes 120 can cause convection in the fluid 114, thereby bringing the cooler fluid 114 into contact with the electrode 120. This convection effect helps to circulate heat energy throughout the contained fluid 114 for more uniform heating.

[0041] In some examples, the fluid port 160 is located on the side wall of the solution heating container 100, closer to the "top" of the solution heating container 100 than to the "bottom" of the solution heating container 100 where the electrode 120 is located. In some examples, the fluid port 160 is located on the side wall of the solution heating container 100, closer to the "bottom" of the solution heating container 100 than to the "top" of the solution heating container 100, for example, to allow the discharge of fluid weight to increase the pressure when fluid 114 is delivered from the reservoir 112.

[0042] According to some embodiments, the solution heating container 100 includes a lid 150. The lid 150 may be configured to have a leak-proof or otherwise watertight seal around a mating surface with the solution heating container 100, thereby preventing fluid leakage when in the closed position and providing access to the internal reservoir 112 when in the open position. In various embodiments, the lid 150 may include a combination of conventional structures such as deformable members that facilitate sealing, latches, hinges, handles, channels, threaded connections, etc. Although shown as including the entire surface of the solution heating container 100, this disclosure contemplates embodiments in which the lid 150 occupies only a portion of a given surface of the outer wall 110 of the solution heating container 100. In some examples, the lid 150 is oriented at the "top" of the solution heating container 100 relative to the electrodes 120 on the "bottom" surface of the internal reservoir 112.

[0043] Figure 1B A view of a solution heating container 100 is shown, in which the recess 135 and the electrical contact 130 are more readily visible. In some examples, the electrical contact 130 is disposed on the outer surface of the recess 135 in the outer wall 110 and connected to the corresponding electrode 120 via a wire passing through the outer wall 110. In some examples, the electrical contact 130 is embedded within the outer wall 110 and has sufficient thickness such that a first surface of a given electrical contact (e.g., 130 A and 130 B) is flush with the surface of the recess 135, and a second surface of the electrical contact is directly connected to the corresponding electrode (e.g., 120 A and 120 B) by brazing, welding, or other electrically compatible attachment. This disclosure also contemplates embodiments in which the given electrical contact 130 and electrode 120 may be a single, unified component.

[0044] Figure 2 A direct charging device 200 for supplying current to electrical contacts 130 is shown. The charging device 200 includes a housing 210, and third electrical contacts 230A and fourth electrical contacts 230B (collectively referred to as charger contacts 230) are disposed within the housing 210. The housing 210 is shaped such that the ends of the housing dimensionally mate with the inner surface of a recess 135, such that when the charging device 200 is inserted into the recess 135, the first electrical contact 130A aligns with the third electrical contact 230A, and the second electrical contact 130B aligns with the fourth electrical contact 230B.

[0045] When physically and electrically connected to the fluid container 100, the charging device 200 may be referred to as being in an engaged configuration, such that in the engaged configuration, the charging device 200 is at least partially disposed within the recess 135, and the electrodes 120 and electrical contacts 130 are aligned with each other, such that electricity is delivered from the charging device 200 through the fluid 114 between the electrodes 120, thereby heating the fluid. In some embodiments, the charging device 200 has a disengaged configuration, such that the charging device 200 is physically isolated from the fluid container 100 (e.g., pulled out and removed from the recess 135).

[0046] In the illustrated embodiment, the charging device is circular, aligned with the uniform semi-circular rectangular outline of the illustrated recess 135; however, other corresponding shapes are contemplated. This disclosure also contemplates embodiments in which the charging device 200 and recess 135 employ conventional alignment structures (e.g., pins and holes, tabs and slots, non-circular mating forms, plugs, ports, magnets, etc.) to align the charger contacts 230 with the electrical contacts 130. The direct charging device 200 also includes a power cable as a means of receiving current (e.g., from a wall socket or battery), but may also include a battery or other local power source.

Figures 1A to 1B The embodiments described herein, Figures 3A to 3B The solution heating container 100 shown may include a fluid port 160, a cover 150, an outer wall 110, a first electrode 120A, a second electrode 120B, a recess 135, and contains fluid 114. Electricity is delivered to the electrode 120 via an induced current in the receiver antenna 310.

[0048] Figure 3B An embodiment according to this disclosure is shown. Figure 3A An alternative view of the solution heating container 100, where some features are more easily seen. The receiver antenna 310 is a wire coil configured to work with a magnetic coil (e.g., used as a magnetic loop antenna), such as... Figure 4 The magnetic charging device interacts with the magnetic coil. When exposed to a magnetic field of compatible magnitude and orientation, a current is induced in the receiver antenna 310, a first end of which is electrically connected to a first electrode 120A, and a second end of which is electrically connected to a second electrode 120B. Electrode 120 interacts with the electrode... Figures 1A to 1B The direct current delivery embodiment interacts with the fluid 114 in the same manner, for example, current passes through the fluid 114 between the electrodes 120.

[0049] Figure 4 A magnetic charging device 400 is shown, which includes a magnetic coil 410 and, similar to a direct charging device 200, includes a housing 210 and a power cable 220. The magnetic coil 410 receives current from an external source (e.g., a wall socket or battery) via the power cable 220. The magnetic coil 410 is configured to generate a magnetic field compatible with a receiver antenna 310 of a solution heating container 100 when current passes through it. When the magnetic charging device 400 is sufficiently close to the receiver antenna 310, the magnetic field generated by the magnetic coil 410 induces a current in the receiver antenna 310. The induced current is supplied to electrodes 120 in the solution heating container 100.

[0050] When physically and electrically connected to the fluid container 100, the magnetic charging device 400 may be referred to as being in an engaged configuration, such that in the engaged configuration, the magnetic charging device 400 is at least partially disposed within the recess 135, and the magnetic loop antenna 410 and the receiver antenna 310 are aligned with each other, allowing power to be wirelessly delivered from the magnetic charging device 400, which generates a magnetic field configured to induce a current in the receiver antenna 310. This magnetic field drives the current through the fluid 114 contained in the reservoir 112 between the electrodes 120, thereby heating the fluid 144. In some embodiments, the magnetic charging device 400 has a disengaged configuration, such that the magnetic charging device 400 is physically isolated from the fluid container 100 (e.g., pulled out and removed from the recess 135).

[0051] Although the discussion primarily concerns heating devices provided by a pair of electrodes 120, this disclosure contemplates the possibility of combining heating pads, heating containers, heating tanks, etc., with the described heating devices to amplify the rate at which the fluid 114 is heated. Therefore, in various embodiments, the described container 100 may not have electrodes 120 and contacts 130, as... Figure 5 As shown. In various examples, this embodiment without a heating device may include or omit the recess 135.
