Self-expanding compression belt and infusion system

Abstract

A self-expanding compression band and an infusion system are provided. The self-expanding compression band includes first and second compartments formed within the self-expanding compression band and containing respective substances. The first and second compartments are configured to rupture in response to a force applied to the outer surface of the self-expanding compression band, which causes the respective substances to bind to initiate a chemical reaction, thereby creating a reaction force on the inner surface of the self-expanding compression band that causes the self-expanding compression band to expand. The self-expanding compression band is further configured to expand such that a first opening at a first end of the self-expanding compression band and a second opening at a second end opposite the first end of the self-expanding compression band expand to a tube sufficient to receive a container through the first opening and a container through the second opening.

Description

Technical Field

[0001] The present disclosure relates generally to medical fluid dispensing systems and, more particularly, to self-expanding pressurization belts and infusion systems for dispensing medical fluids from intravenous bags. Background Art

[0002] Medical treatments often include infusing medical fluids (e.g., saline solutions or liquid medications) into patients using an infusion pump that dispenses the medical fluids from an intravenous (IV) bag to the patient. When an infusion pump is not available, medical personnel manually compress or otherwise squeeze the IV bag to administer the medical fluid. Manually compressing the IV bag can cause hand fatigue, which is a great inconvenience for medical personnel.

[0003] Therefore, there is a need for a device and method of using the same that can dispense medical fluid from an intravenous (IV) bag to a patient without tiring the medical staff. Utility Model Content

[0004] The disclosed subject matter relates to a self-inflating pressurization belt for use with an IV bag. In some embodiments, the self-inflating pressurization belt includes an outer surface and an inner surface (e.g., an expandable body). The inner surface includes a first film layer formed within and along the inner surface at a first position, and a second film layer formed within and along the inner surface at a second position. The first film layer forms a first compartment, which is configured to accommodate a first substance, and the second film layer forms a second compartment separated from the first compartment, which is configured to accommodate a second substance isolated from the first substance. The first film layer is configured to rupture in response to a force applied to the outer surface of the self-inflating pressurization belt, and the second film layer is also configured to rupture in response to a force applied to the outer surface of the self-inflating pressurization belt. The self-inflating pressurization belt is configured so that when the first and second compartments rupture in response to a force applied to the outer surface, the first substance and the second substance combine to initiate a chemical reaction, thereby generating a reaction force on the inner surface of the self-inflating pressurization belt, which causes the self-inflating pressurization belt to expand. The self-inflating pressurization belt is further configured to expand so that a first opening at a first end of the self-inflating pressurization belt and a second opening at a second end opposite to the first end of the self-inflating pressurization belt are enlarged to be sufficient to receive the container through the first opening and receive the tubing of the container through the second opening. In some embodiments, after the container and the tubing of the container are received via the first end and the second end of the self-inflating pressurization belt, respectively, and the reaction force applied to the inner surface of the self-inflating pressurization belt is removed when the chemical reaction is completed, the self-inflating pressurization belt is configured to self-contract and compress the container so that the fluid flowing out of the container is accelerated when flowing.

[0005] In some embodiments, the first compartment is adjacent to the second compartment in the self-inflating pressurization belt. Alternatively, in some embodiments, the first compartment is formed in a first portion of the self-inflating pressurization belt adjacent to the first end, and the second compartment is formed in a second portion of the self-inflating pressurization belt at the second end opposite to the first portion, or vice versa.

[0006] In some embodiments, the force applied to the outer surface of the self-inflating pressurization belt is a compressive force applied to the first end and the second end of the self-inflating pressurization belt. Alternatively, in some embodiments, the force applied to the outer surface of the self-inflating pressurization belt is a tensile force applied to the first end and the second end of the self-inflating pressurization belt. In some embodiments, the first compartment is configured to rupture before the second compartment when a force is applied to the outer surface of the self-inflating pressurization belt. In some embodiments, the first compartment includes a first predetermined amount of a first substance, and the second compartment includes a second predetermined amount of a second substance, and the first predetermined amount of the first substance and the second predetermined amount of the second substance are based on the volume of the self-inflating pressurization belt. In some embodiments, the self-inflating pressurization belt includes an elastic material so that after the self-inflating pressurization belt expands, the self-inflating pressurization belt self-contracts at a predetermined rate until the self-inflating pressurization belt returns to an unexpanded state.

[0007] On the other hand, a method for inflating a self-inflating pressurized belt is disclosed. The method includes providing a self-inflating pressurized belt having a first film layer formed in and along an inner surface at a first position and a second film layer formed in and along the inner surface at a second position. The first film layer forms a first compartment configured to accommodate a first substance, and the second film layer forms a second compartment separated from the first compartment, configured to accommodate a second substance isolated from the first substance. The method includes applying a force to the outer surface of the self-inflating pressurized belt, the force causing the first film layer and the second film layer to rupture, thereby allowing the first substance and the second substance to combine. The method also includes initiating a chemical reaction based on the combination of the first substance and the second substance to generate a reaction force on the inner surface of the self-inflating pressurized belt, the reaction force causing the self-inflating pressurized belt to expand, so that the first opening at the first end of the self-inflating pressurized belt and the second opening at the second end opposite to the first end of the self-inflating pressurized belt are expanded to be sufficient to accommodate a container passing through the first opening and a pipe fitting of the container passing through the second opening. The method further includes receiving the container and the pipe fitting of the container via the first end and the second end of the self-inflating pressurized belt. In some embodiments, the method includes initiating self-contraction of the self-inflating pressurization belt and compression of the container after a container and a tube of the container are received via a first end and a second end of the self-inflating pressurization belt, respectively, and a reaction force applied to an inner surface of the self-inflating pressurization belt is removed when a chemical reaction is completed, so that a fluid flowing out of the container is accelerated while flowing.

[0008] In some embodiments, the self-inflating pressure belt comprises an elastic material so that after the self-inflating pressure belt is expanded, the self-inflating pressure belt self-contracts at a predetermined rate until the self-inflating pressure belt returns to an unexpanded state. In some embodiments, the force applied to the outer surface of the self-inflating pressure belt is a compressive force applied to the first end and the second end of the self-inflating pressure belt. Alternatively, in some embodiments, the force applied to the outer surface of the self-inflating pressure belt is a tensile force applied to the first end and the second end of the self-inflating pressure belt.

[0009] In some embodiments, within the self-inflating pressurization belt, the first compartment is adjacent to the second compartment. Alternatively, in some embodiments, the first compartment is formed in a first portion adjacent to the first end of the self-inflating pressurization belt, and the second compartment is formed in a second portion of the self-inflating pressurization belt opposite to the first portion and adjacent to the second end, or vice versa. In some embodiments, the first compartment is configured to rupture before the second compartment when a force is applied to the outer surface of the self-inflating pressurization belt. In some embodiments, the first compartment includes a first predetermined amount of a first substance, and the second compartment includes a second predetermined amount of a second substance. The first predetermined amount of the first substance and the second predetermined amount of the second substance are based on the volume of the self-inflating pressurization belt.

[0010] Note that the various embodiments described above can be combined with other embodiments described herein (e.g., maintaining the impedance of a single or a group of neuromuscular signal sensors can be combined with impedance matching so that the impedance can be both matched and maintained within a specific range of impedance values).

[0017] Numerous details are described herein in order to provide a thorough understanding of the example implementations shown in the accompanying drawings. However, some embodiments may be practiced without many of the specific details, and the scope of the claims is limited only by those features and aspects specifically recited in the claims. In addition, well-known processes, components, and materials are not described in detail to avoid obscuring relevant aspects of the embodiments described herein.

[0018] The disclosed self-inflating pressurization belt is configured to receive an IV bag and accelerate medical fluid from the IV bag to a patient for treatment. In particular, the self-inflating pressurization belt is configured to self-expand in response to a force applied to the body of the self-inflating pressurization belt. After the force is removed from the body of the self-inflating pressurization belt and the body of the self-inflating pressurization belt stretches to an expanded state. In some embodiments, the self-inflating pressurization belt self-expands due to a chemical reaction caused by at least two substances contained within the self-inflating pressurization belt, and the at least two substances mix in response to the force applied to the self-inflating pressurization belt. The self-inflating pressurization belt is further configured to receive an IV bag and self-contract, thereby compressing the IV bag and accelerating the flow of fluid from the IV bag to the patient.

[0019] Figure 1 An IV pump for administering medical fluid to a patient is shown. The IV pump 30 includes a controller 32 and one or more pump modules 34. The IV kit 20 is connected between a container 36 (e.g., an IV bag) of medical fluid and the patient 5. During operation, the IV pump 30 delivers the medical fluid to the patient 5. The IV pump 30 is configured to administer the medical fluid to the patient 5 at a predetermined and uniform rate. When the IV pump 30 is unavailable or otherwise out of service, the medical fluid can be dispensed to the patient 5 by applying force to the container 36 (e.g., squeezing the container 36). In some embodiments, the self-expanding compression belt 200 ( Figures 2A-2D ) is used in place of IV pump 30 to administer medical fluids to patient 5, as described below.

[0020] Figures 2A-2DA self-inflating pressurized belt according to some embodiments is illustrated. The self-inflating pressurized belt 200 includes an expandable body 210, a first compartment 220, and a second compartment 225. The first compartment 220 is formed in the expandable body 210 and along the inner surface of the expandable body, and is configured to accommodate a first substance. More specifically, in some embodiments, the first compartment 220 is formed by a first film layer 220a (represented by a vertical fill pattern), which is formed in the inner surface and along the inner surface at a first position. The second compartment 225 is formed in the expandable body 210 and along the expandable body, and is configured to accommodate a second substance isolated from the first substance. Similar to the first compartment 220, in some embodiments, the second compartment 225 is formed by a second film layer 225a (represented by a horizontal fill pattern), which is formed at a second position along the inner surface and in the inner surface. As described in detail below, the self-inflating pressurization belt 200 is configured such that when the first compartment 220 and the second compartment 225 are ruptured in response to a force applied to the outer surface, the first substance and the second substance are combined to initiate a chemical reaction, thereby generating a reaction force on the inner surface of the self-inflating pressurization belt, which causes the self-inflating pressurization belt to expand. The self-inflating pressurization belt 200 is further configured to expand such that a first opening at a first end of the self-inflating pressurization belt and a second opening at a second end opposite to the first end of the self-inflating pressurization belt 200 are enlarged to be sufficient to receive the container 36 through the first opening and receive the tubing of the container through the second opening.

[0021] In some embodiments, within the expandable body 210, the first compartment 220 is adjacent to the second compartment 225. For example, the first compartment 220 may be disposed above the second compartment 225, or vice versa. As described above, in some embodiments, the first compartment 220 is formed at a first portion of the expandable body 210 (e.g., by a rupturable first membrane layer 220a that holds a first substance in isolation), and the second compartment 225 is formed at a second portion of the expandable body 210 that is opposite to the first portion (e.g., by a rupturable second membrane layer 220b that holds a second substance in isolation). For example, the first compartment 220 may be formed near the first end 212, and the second compartment 225 may be formed near the second end 214. In some embodiments, the first membrane layer and the second membrane layer include one of foil, plastic, paper, and / or other rupturable or breakable materials.

[0022] In some embodiments, the first compartment 220 includes a first predetermined amount of a first substance, and the second compartment 225 includes a second predetermined amount of a second substance. When the first substance and the second substance are mixed (combined or when they are in contact with each other), a chemical reaction is caused to generate at least one gas. The generated gas expands and applies a reaction force 257 ( Figure 2B). More specifically, the chemical reaction caused by the first substance and the second substance generates a reaction force 257 that causes the expandable body 210 to expand. In some embodiments, the first predetermined amount of the first substance and the second predetermined amount of the second substance are based on the volume of the expandable body. The first substance and the second substance can be at least any two substances that produce a harmless gas when mixed. For example, the first substance can be vinegar and the second substance can be baking soda.

[0023] In response to the application of the outer surface 211a ( Figure 2B ) force 230, the first substance and the second substance are released from the first compartment 220 and the second compartment 225. In particular, the first and second film layers 220a and 225a are ruptured 227, so that the first and second substances are combined to cause a chemical reaction. Figure 2B As shown, the chemical reaction generates a reaction force 257, which is applied to the inner surface 211b ( Figure 2B ), causing the expandable body 210 to expand so that at least the first opening 250 ( Figure 2B ) and a second opening 255 at a second end 214 opposite to the first end 212 of the expandable body 210 ( Figure 2B ) expands. The first end 212 is configured as a receiving container and the second end is configured as a tube of the receiving container. In other words, the self-expanding pressure belt 200 self-expands in response to the force 230 applied to the expandable body 210. In some embodiments, when the force 230 is applied to the expandable body 210, the first compartment 220 is configured to rupture before the second compartment 225, or vice versa. Alternatively, in some embodiments, the first compartment and the second compartment are configured to rupture simultaneously.

[0024] In some embodiments, the first and second openings 250 and 255 are sealed until a force 230 is applied to the outer surface 211a of the expandable body 210 and the first and second membrane layers 220a and 225a are ruptured. The first and second openings 250 and 255 remain relatively small (or sealed) until the expandable body 210 reaches a predetermined size so that the first and second substances do not escape from the expandable body 210 and / or the chemical reaction ends before completion. In some embodiments, relatively small means that the first and second openings are such that air or fluid cannot escape through the first and second openings 250 and 255. In some embodiments, the predetermined size is at least three quarters (3 / 4) of the total size of the expandable body 210. Alternatively, in some embodiments, the self-inflating pressure belt 200 is packaged in a sealed container that causes the expandable body to expand in response to a force 230 applied to the sealed container, and once expanded, the sealed container can be ruptured and the self-inflating pressure belt 200 is removed from the sealed container.

[0025] The force 230 (e.g., breaking the compartment) can be a compressive force (e.g., forces 230a and 230b) applied to the first end 212 and the second end 214 (opposite the first end 212) of the expandable body 210. For example, the medical staff can compress (e.g., squeeze) the first end 212 and the second end 214 of the expandable body 210 between their hands to apply the compressive forces 230a and 230b, press the first end 212 or the second end 214 of the expandable body 210 against a surface (e.g., a table, a wall, etc.), etc. Alternatively, in some embodiments, the force 230 is a tensile force (represented by multi-directional arrows 230a and 230b) applied to the first end 212 and the second end 214 of the expandable body 210. For example, the medical staff can pull the first end 212 and the second end 214 of the expandable body 210 in opposite directions. In some embodiments, the force 230 is a lateral force that can be applied to the first end 212 of the expandable body 210 and the second end 214 of the expandable body 210. Alternatively, in some embodiments, the force 230 is applied to the sides 216 and 218 of the expandable body 210. The above examples are non-limiting, and any force that ruptures the first and second film layers 220a and 225a can be used.

[0026] Go to Figure 2B , the expandable body 210 of the self-inflating pressurizing belt 200 expands due to the chemical reaction caused by the first and second substances. More specifically, the chemical reaction caused by the first and second substances generates one or more reaction forces 257a and 257b (e.g., pressure), which are applied to the inner surface 211b of the expandable body 210, causing the expandable body 210 to expand so that the expandable body 210 can receive the container 36 and the tube 213 of the container 36. Although not shown, the reaction force 257 is applied in all directions, causing the expandable body to expand at a faster rate. The reaction force 257 is applied to the inner surface 211b of the expandable body 210 until the chemical reaction between the first and second substances is completed. The first end 212 of the expandable body 210 includes a first opening 250 configured to receive the container 36 (when the expandable body 210 is expanded), and the second end 214 of the expandable body 210 includes a second opening 255 configured to receive the tube 213 of the container 36 (such as Figure 2C In particular, when the expandable body 210 expands, the first opening 250 at the first end 212 of the expandable body 210 and the second opening 255 at the second end 214 opposite to the first end 212 of the expandable body 210 are enlarged, so that the first end can accommodate the container 36, and the second end can accommodate the tube 213 of the container 36.

[0027] Figure 2CThe self-expanding compression belt 200 is shown with the expandable body 210 substantially expanded. Figure 2B As described, after force 230 is applied to the outer surface 211a of the expandable body 210 causing the first and second membrane layers 220a and 225b to rupture, one or more reaction forces 257a and 257b (generated by the chemical reaction when the first and second substances are combined) applied to the inner surface 211b of the expandable body 210 cause the expandable body 210 to expand so that the expandable body 210 can accommodate the container 36 and the tube 213 of the container 36. The expandable body 210 continues to expand until the chemical reaction between the first and second substances is completed. Once substantially expanded, the container 36 can be placed in the expandable body 210 of the self-inflating pressurization belt 200. In some embodiments, substantially expanded means that the expandable body 210 expands so that it can accommodate at least 70% of the container 36. As described above with reference to Figure 2B As described above, after the expandable body 210 is expanded, the tubular member 213 of the container 36 can be received by the second opening 255 of the expandable body 210. The second opening 255 of the expandable body 210 does not hinder or block the flow of the medical fluid from the container 36 (to the patient). By allowing the tubular member 213 of the container 36 to be received in the second opening 255 without hindering the flow of the medical fluid, the self-expanding pressurization belt 200 can effectively administer the medical fluid from the container 36 to the patient without hindering the flow of the medical fluid.

[0028] Figure 2D A container placed within the expandable body 210 via the first opening 250 is shown, and the container is held within the expandable body 210 as it is compressed by the self-contraction of the expandable body 210. As the expandable body 210 contracts, the medical fluid flowing out of the container 36 (when allowed to flow) is accelerated out of the container 36 (i.e., the medical fluid flows from the container 36 to the patient). In some embodiments, once the reaction force 257 is removed from the inner surface 211b of the expandable body 210, the expandable body 210 self-contracts. In some embodiments, the expandable body 210 is formed of an elastic material so that after the expandable body 210 is expanded (e.g., when a chemical reaction between at least the first and second substances is ongoing) and self-contracts at a predetermined rate (e.g., after the chemical reaction between at least the first and second substances ends (i.e., the production of non-toxic gas that causes the expandable body 210 to expand) until the expandable body 210 returns to an unexpanded state. The predetermined rate at which the expandable body 210 self-contracts is based at least in part on the elastic material. In some embodiments, the elastic material includes rubber, latex, silicone, polyurethane, nylon, thermoplastic elastomers, and / or other flexible materials that expand and self-contract based on the application of force.

[0029] Figure 3is a flow chart illustrating a method 300 for accelerating the flow of a fluid from a container according to some embodiments. The method 300 may be referred to above. Figures 2A-2D The method may include at least some but not all of the operations shown in method 300 performed in a different order. In addition, a method consistent with the present disclosure may include at least two or more steps, such as steps in method 300, that overlap in time or are performed almost simultaneously. The method 300 includes providing (310) a self-inflating pressurization belt having an outer surface and an inner surface, and including a first film layer formed at a first position within and along the inner surface, and a second film layer formed at a second position within and along the inner surface. The first film layer forms a first compartment, which is configured to accommodate a first substance, and the second film layer forms a second compartment separated from the first compartment, which is configured to accommodate a second substance isolated from the first substance.

[0030] The method 300 includes applying a force (320) to the outer surface of the self-expanding pressurized belt, the force causing the first film layer and the second film layer to rupture, thereby allowing the first substance and the second substance to combine. Figure 2A-2C As described, the force applied to a portion of the expandable body 210 of the self-expanding pressurization belt 200 causes the first and second compartments 220 and 225 to rupture. In some embodiments, the first compartment is configured to rupture before the second compartment, or vice versa. Alternatively, in some embodiments, the first and second compartments are configured to rupture simultaneously. In some embodiments, the force applied to the expandable body is a compressive force or a tensile force. In some embodiments, within the expandable body, the first compartment is adjacent to the second compartment.

[0031] The method includes initiating (330) a chemical reaction based on the combination of the first and second substances (which allows the first and second substances to combine when a force is applied to the outer surface of the expandable body and the first and second compartments are ruptured) to generate a reaction force on the inner surface of the self-inflating pressurization band, which causes the self-inflating pressurization band to expand so that a first opening at a first end of the self-inflating pressurization band and a second opening at a second end opposite the first end of the self-inflating pressurization band are large enough to receive a container (e.g., an IV bag) through the first opening and a tubing of the container (e.g., tubing 213 of an IV bag) through the second opening. In some embodiments, the first and second openings are sealed until the first and second thin layers are ruptured. Once a force is applied to the outer surface of the expandable body, the first and second openings remain substantially small until the expandable body reaches a predetermined size, which allows the chemical reaction to not be interrupted. In some embodiments, the predetermined size is at least three quarters (3 / 4) of the total size of the expandable body 210.

[0032] In some embodiments, the expandable body is formed of an elastic material such that after the expandable body is expanded, the expandable body self-contracts at a predetermined rate until the expandable body returns to an unexpanded state. In some embodiments, the first compartment includes a first predetermined amount of a first substance and the second compartment includes a second predetermined amount of a second substance. The first predetermined amount of the first substance and the second predetermined amount of the second substance are based on the volume of the expandable body. Figures 2A-2D Additional information about the first and second substances is provided.

[0033] The method 300 includes receiving (340) a container and a tubular component of the container via a first end and a second end of an expandable body, and after the container and the tubular component of the container are received via the first end and the second end of a self-inflating pressurization belt, respectively, and a reaction force applied to an inner surface of the self-inflating pressurization belt is removed when a chemical reaction is completed, initiating (350) self-contraction of the self-inflating pressurization belt and compression of the container, so that a fluid flowing out of the container is accelerated when flowing.

[0034] Figure 4 4 is a conceptual diagram illustrating an example electronic system 400 for controlling a pump according to aspects of the subject technology. The electronic system 400 may be a specially configured computing device for executing Figures 1 to 4 The components and processes associated with the provided software include, but are not limited to, the controller 32 of the IV pump 30. Figures 1 to 3 For purposes of this disclosure, electronic system 400 may be representative.

[0035] The electronic system 400 may include various types of computer-readable media and interfaces for various other types of computer-readable media. In the depicted example, the electronic system 400 includes a bus 408, a processing unit 412, a system memory 404, a read-only memory (ROM) 410, a permanent storage device 402, an input device interface 414, an output device interface 406, and one or more network interfaces 416. In some implementations, the electronic system 400 may include or be integrated with other computing devices or circuits for operating the various components and processes previously described.

[0036] Bus 408 collectively represents all system, peripheral, and chipset buses that communicatively connect the various internal devices of electronic system 400. For example, bus 408 communicatively connects processing unit 412 with ROM 410, system memory 404, and permanent storage 402.

[0037] Processing unit 412 fetches instructions to be executed and data to be processed from these various memory units in order to perform the processes of the subject disclosure. In various implementations, the processing unit may be a single processor or a multi-core processor.

[0038] ROM 410 stores static data and instructions required by processing unit 412 and other modules of the electronic system. On the other hand, permanent storage 402 is a read-write memory device. This device is a non-volatile storage unit that stores instructions and data even when the electronic system 400 is turned off. Some embodiments of the subject disclosure use a mass storage device (such as a magnetic or optical disk and its corresponding disk drive) as permanent storage 402.

[0039] Some embodiments use a removable storage device (e.g., a floppy disk, a flash drive, and its corresponding disk drive) as a permanent storage device 402. Similar to the permanent storage device 402, the system memory 404 is a read-write memory device. However, unlike the storage device 402, the system memory 404 is a volatile read-write memory, such as a random access memory. The system memory 404 stores some instructions and data required by the processor at runtime. In some embodiments, the processes disclosed in the present subject matter are stored in the system memory 404, the permanent storage device 402, and / or the ROM 410. The processing unit 412 extracts the instructions to be executed and the data to be processed from these different memory units in order to perform the processes of some embodiments. Such storage devices and / or memory devices 402, 404 can represent the memory of the controller 32.

[0040] Bus 408 is also connected to input and output device interfaces 414 and 406. Input device interface 414 enables a user to communicate information and select commands to the electronic system. Input devices used with input device interface 414 include, for example, alphanumeric keyboards and pointing devices (also called "cursor control devices"), such as Figure 1 The output device interface 406 (e.g., in Figure 1 The controller 60 of the embodiment of the present invention is shown as a display (shown as a display in the controller 60 of the embodiment of the present invention) capable of displaying, for example, images generated by the electronic system 400. Output devices used with the output device interface 406 include, for example, printers and display devices, such as cathode ray tubes (CRT) or liquid crystal displays (LCD).
