DETAILED DESCRIPTION

[0028] The patent application relates to a pressure infusion device unit having a support unit for fixing an infusion bag and controlling an infusion system in a gravity-independent, adjustable manner, where the pressure infusion device can be mounted on a human body or other near flat surface. An infusion bag can be positioned in the support unit to receive equal pressure from both sides during infusion, and the flow rate of infusion fluid in the infusion bag can be reliably controlled, and optionally accelerated or decelerated.

[0029] The present invention overcomes shortcomings in conventional systems by providing an infusion bag holder unit that can be placed within or below the line of the human body and simply and securely mounted on a nearly flat surface, even on the patient's body. An infusion bag described herein can be symmetrically pressed from both sides such that the flow rate of the infusion fluid in the infusion bag can be reliably controlled, optionally accelerated or decelerated, and the infusion solution set to flow as the patient moves or moves almost unchanged. The flow rate of infusion fluid flowing out of the infusion bag in the support unit is ensured and is independent of gravity, maintaining the benefits of using overpressure when using the system and eliminating all of the dangers listed above and utilizing other practical options all at once. As such, the infusion bag holder described herein can be widely used.

[0030] The use of a gravity independent pressurized support unit with its special infusion set, which signals flow through a special turbine instead of a drip chamber, achieves an unattended design that reduces the burden on suppliers. Recognizing the potential of the device to accommodate up to two infusion bags at the same time and to provide the patient with a doubled amount of fluid, or simultaneously deliver two different solutions to the human bloodstream via an implanted, inserted, or drilled cannula, needle, or via a catheter without automatically applying hydrostatic pressure due to gravitational pull which automatically stops and closes the vein due to a stop valve due to failure due to malfunctioning, vacuum formation in the patient's veins for safe and minimal monitoring applications.

[0031] Accordingly, a pressure infusion device is described as having a pressure gauge and control unit for securing an infusion bag and for controlling the infusion system in a gravity-independent, adjustable manner, where an infusion bag containing an infusion fluid, and a tubular end portion attached thereto, is a standard part of an infusion system and ends in a cannula. The tube assembly is provided with a flow control, at least one drug delivery port, a non-return valve and a flow indicator, and a turbine. In the present invention, the infusion bag can be housed in a support unit consisting of two overlapping cross-sections, symmetrically overlapping housing sides and a pressure gauge and pressure relief assembly, such that the gas lines exiting in the housings are connected to a pressure gauge, and a pressure relief assembly and a valve are connected.

[0032] The two walls of the support unit are connected to each other on at least two sides, preferably on their longitudinal sides, and the open portion enclosed by the two pouches is a compartment into which an infusion bag can be placed. The walls are of a flexible material, having two walls and forming a closed airspace within themselves.

[0033] A gas line can be hermetically connected to both housings, the other ends of the gas lines being connected to a single pole of a three-pole connector, and the third line of the connector being connected to a gas line that is connected to the pressure gauge and pressure limiter. The gas line can be connected to the lower part of the pressure gauge and pressure relief unit, and also connected to a pump with a valve.

[0034] The pressure measuring and pressure limiting unit is connected to the gas line and its cylindrical housing includes a piston. The lower part of the piston in the housing has a silicone sealing ring which seals the space of the housing under the piston, the lower part of the housing having a hole. The inside wall of the house has a longitudinal groove in the longitudinal direction which starts at the top edge of the house, but does not reach the bottom of the house. The purpose of milling is to release air through the silicone sealing ring by intentional leakage, thereby controlling the maximum air pressure in the system. In the housing, the piston is surrounded by a spring and secured by a closure cap to the housing. The lower part of the spring is fixed above the silicone sealing ring and the upper pole is fixed on the inner surface of the cap. The milling ends at a height above the bottom of the housing that reaches the height of the piston silicone ring against the spring when the air pressure inside the gas pipe and casing rises to 400 mmHg (53328,955 Pa).

[0035] In the lower part of the housing, there is a material-connected connection piece with two housing outlets, one outlet connected to the gas line to the connection unit and the other outlet to the gas line to the rubber pump. With this solution, the pump, the gas lines, the pressure gauge and pressure relief unit, and the two housings form a solid gas space.

[0036] The infusion bag placed in the support unit is secured by attaching the closure tabs to a closure by attaching the closure tabs secured to the lower and upper portions of the lower enclosure to a hook-and-loop fastener on the outer surface of the enclosure top case. The compartment is thus partially closed, keeping the infusion bag stable.

[0037] The size of the unit is characterized by the fact that an infusion bag of a given volume can be easily inserted into the compartment. Suitably, the double-walled, closed-wall enclosures of the flexible material have the shape of an infusion bag, preferably rectangular. On the lower surface of the support unit, on the outer surface of the lower case, there is an adhesive element provided with a protective layer. The adhesive member fits well to the adhesive surface of the mounting surface. The adhesive element and the attachment surface are fastened to each other with a fastener. The attachment surface is fixed to the human body or to any near-flat surface by means of an adhesive.

[0038] Turning now to the figures, FIG. 1 is a top plan view of a pressure infusion device 100 and FIG. 7 is a top perspective view of the pressure infusion device 100. Referring to these figures collectively, the pressure infusion device 100 includes a support unit 101. In some embodiments, the support unit 101 comprises an air-filled double-walled housing configured to retain an infusion bag 110 or other infusion device, generally referred to herein as an infusion, where the infusion bag 110 is shown in FIGS. 2 and 8. An infusion bag 110 can include a traditional infusion bag comprising a liquid, such as blood, solution, or other substance as can be appreciated. The double-walled housing of the support unit 101 can include a first wall 102a and a second wall 102b (collectively walls 102). As the walls 102 of the support unit 101 symmetrically overlap, only the first wall 102a (e.g., a top wall) is shown in FIG. 1. However, both the first wall 102a and the second wall 102b are shown in FIG. 7.

[0039] Notably, the second wall 102b (e.g., the top wall) comprises a closure 107 (or a closing mechanism), such as a hook-and-loop fastener, which can be secured in a longitudinal direction in a central part thereof. Locking tabs 105a, 150b (collectively locking tabs 105) project laterally from the support unit 101 such that the locking tabs 105 extend beyond outermost edges of the walls 102. The locking tabs 105 can include an end secured to the first wall 102a (e.g., the bottom wall) and can be releasably attached to the closure 107. The locking tabs 105 can include a flexible and bendable body, as can be appreciated. Similar, the walls 102 of the support unit 101 can be formed of a flexible material, such as plastic or other flexible polymer, and can be double-walled to form a closed air space. For instance, the walls 102 can be joined to one another along their longitudinal side at a connecting strip 108, which can include sewing, welding, or other suitable connection mechanisms.

[0040] The walls 102 can include apertures 130 on their outer surfaces, respectively, through or to which a gas line 109 (also referred to as tubing) is hermetically connected. In some embodiments, ends of the gas lines 109 can be connected to a connector unit 111 (e.g., a three-pole connector unit 111), shown in FIG. 1, which may be a three-way or a Y-connector in some embodiments. The other end of the gas line 109 can be connected to a third pole of the connector unit 111, and can be provided with a pressure gauge and pressure control unit 113 connected to the gas line 109 in some embodiments. A retaining ring 122 can secure the pressure gauge and pressure control unit 113 to the gas line 109. The pressure gauge and pressure control unit 113 can be connected to a pump 115 provided with a valve 114 via a gas line 109. The pump 115 can include a rubber pump in some embodiments.

[0041] In various embodiments, the pressure gauge and pressure control unit 113 can include a cylindrical housing 119, and can further include a piston 121. In the housing 119, the piston 121 can be surrounded by a spring (not shown) and can be secured by a closure cap 120. A connection piece 126 in a lower part of the housing 119, which is formed in a continuous manner with the housing 119, can include two outlets, where one outlet is connected to the gas line 109 to the connector unit 111, and the other outlet to the gas line 109 to the pump 115. As shown in FIG. 1, the connecting element 106 serves to connect and, if necessary, quickly disconnect the gas lines 109 to eliminate overpressure in the entire system.

[0042] FIG. 2 and FIG. 8 are bottom views of the support unit 101. Referring to these figures collectively, on the longitudinal sides of the first wall 102a of the support unit 101, a connecting strip 108 is shown as well as the locking tabs 105 and their attachment to the shorter outer side of the first wall 102a. A fastener 104 (e.g., a hook-and-loop or Velcro fastener, or an adhesive element) can be secured to the outer surface of the first wall 102a. In some embodiments, the fastener 104 (e.g., an adhesive element) can be formed of two overlapping layers, the lower layer being the same as the material of the walls 102, the overlapping layer (as shown) having a hook-and-loop material (e.g., a Velcro material). The two layers can be secured to one another by sewing or other suitable coupling, and the fastener 104 thus formed can be secured to the outer surface of the first wall 102a by a fastening strip 116, such as a circular fastening strip, which can be sewn or welded. A targeting separator projection 117 connected to the edge of the fastener 104 can be made of a continuous material from the lower (non-Velcro) layer. The separator projection 117 allows the protective layer that covers the fastener 104 to be easily removed during use.

[0043] FIG. 3, which is a plan view of a mounting surface, shows the attachment surface 123 having a tear-off projection 124 and a central portion having an adhesive surface 125. When fitted to the attachment surface 123, the targeting separator projection 117 of the fastener 104 is closely aligned with a tear-off projection 124 to direct the engagement, thereby ensuring that the hook-and-loop closure of the fastener 104 is centered on the adhesive surface 125 of the attachment surface 123.

[0044] The side of the attachment surface 123 opposite to the adhesive surface 125 is provided with an adhesive which is covered with a protective layer or protective film during packaging and transport. The adhesive can secure the attachment surface 123 to as many surfaces as possible.

[0045] FIG. 4 and FIG. 9 are front views of the support unit 101. Referring to FIG. 4 first, the wall 102 and the compartment 103 are shown as being defined by its inner surfaces, and the locking tabs 105 in the open position in normal condition (without pressure), not filled with air. FIG. 9 shows the support unit 101 of the pressure infusion device 100 being inflated with air, which can be performed by squeezing the pump 115, directing air through the gas lines 109 into the interior of the support unit 101, as can be appreciated.

[0046] FIG. 5 is a front view of the pressure infusion device which shows air-filled, pressurized walls 102 and an infusion bag 110 in a compartment 103, the drain port 118 of which being covered by a closure when not in use and an infusion tube assembly being connected to a drain port 118 when in use. FIG. 5 shows that the locking tabs 105 at least partially closes the compartment 103, holding an infusion bag 110 positioned therein securely.

[0047] In FIG. 6, two infusion bags 110 are shown placed in a support unit 101. The infusion bags 110 are disposed opposite to each other in the compartment 103 and a plurality of tubing and fittings can be connected to ports 118 of the infusion bags 110, as can be appreciated. According to one or more embodiments, two ports 118 can be connected on both sides of the support unit 101, which can be connected to a gas line 109, where the gas line 109 can be one connected to the connector unit 111, such as a Y-shaped connector unit. For example, a first end of a gas line 109 can be connected to the third pole of the connector unit 111 and a second end thereof can be connected to the pressure measuring and pressure control unit 113. The pressure gauge and pressure control unit 113 can be connected to a pump 115 provided with a valve 114 by another gas line 109. An infusion bag 110 can be placed in the support unit 101 which can completely fill the compartment 103, such as a 500 ml infusion bag. The infusion bag 110 can be fixed in the compartment 103 without moving, by attaching the locking tabs 105 attached to a lower one of the walls 102 to the closure 107 on an upper one of the walls 102.

[0048] According to a further embodiment, the support unit 101 has the same configuration as in the previous example, but the compartment 103 is fitted with two infusion bags 110 having the same volume as the infusion bag 110 in the previous example. The two infusion bags 110 can be disposed opposite to each other, with a discharge on one of the ports 118 facing outwards. According to a further embodiment, the infusion bags 110 are also placed in the support unit 101, but are located on each other facing in the opposite direction to the ports 118.

[0049] Referring again to FIG. 7, in some embodiments, the pressure infusion device 100 can include a plurality of attachment tabs 133a . . . 133n. The attachment tabs 133 can extend downward, in some embodiments, permitting the gas line 109 and other various components of the pressure infusion device 100 to be tightly secured to the support unit 101, creating a compact-type pressure infusion device 100 that can be beneficial in combat and other emergency situations. The attachment tabs 133 can include a button 136 or other attachment mechanism that secures the attachment tabs 133 to a bottom portion of the support unit 101. While FIG. 7 includes four attachment tabs 133, the pressure infusion device 100 can include one, three, or another suitable number of attachment tabs 133.

[0050] FIG. 10 shown a bottom view of the pressure infusion device 100 according to various embodiments of the present disclosure. FIG. 11 shows a front view of the pressure infusion device 100 according to various embodiments of the present disclosure. FIG. 12 is a rear view of the pressure infusion device 100 according to various embodiments of the present disclosure. Also, FIGS. 13 and 14 are side views of the pressure infusion device 100 according to various embodiments of the present disclosure.

[0051] Referring now to FIGS. 15-20, an example application of the pressure infusion device 100 to a human is described. The present invention allows an infusion bag fixed in the support unit 101 to be equally pressurized on both sides when infused. When using the pressure infusion device 100 described herein, a first step can include affixing an adhesive patch 140 to a human body. An inner surface of the adhesive patch 140 (e.g., the surface contacting skin of the human shown in FIG. 15) can include an adhesive that adheres to human skin. An outer surface of the adhesive patch 140 can include a hook-and-loop fastener or other connection for coupling to the pressure infusion device 100. Next, as shown in FIG. 16 and FIG. 17, the pressure infusion device 100 can be secured to the adhesive patch 140, thereby securing the pressure infusion device 100 to the human body. The pressure infusion device 100 is shown as non-inflated in these figures.

[0052] Next, as shown in FIG. 18, an infusion, such as an intravenous (IV) bag, is inserted into the pressure infusion device 100 or, more specifically, into the compartment defined by the walls 102 of the support unit 101. In FIG. 19, the pump 115 is pumped by hand, inflating the double-walled housing of the support unit 101, equally pressurizing both sides of the IV bag or other infusion. In FIG. 20, as the pressure infusion device 100 operates in a gravity-independent manner, the patient can be moved, for example, to a hospital. The IV bag fixed in the support unit 101 receives equal pressure from both sides during infusion, and the flow rate of infusion fluid in the infusion bag can be reliably controlled, optionally accelerated, or decelerated.

[0053] The pressure infusion device 100 can be placed within or below the line of the human body and simply and securely mounted on a nearly flat surface, such as the stomach of the patient's body. The infusion bag described herein can be symmetrically pressed from both sides such that the flow rate of the infusion fluid in the infusion bag can be reliably controlled, optionally accelerated, or decelerated, and the infusion solution set to flow as the patient moves or moves almost unchanged. The flow rate of fluid flowing out of the infusion bag in the support unit 101 can be controlled and is independent of gravity, maintaining the benefits of using pressure when using the system, eliminating various dangers.

[0054] Another example operation is described as follows. For example, a first step can include connecting a tube assembly to an infusion bag after removing a closure cap. The second step can include venting the resulting system and filling the tube assembly with therapeutic solution. The third step can include removing a protective layer from an attachment surface and securing it with an adhesive-coated surface to a patient's body or on another near flat surface. The fourth step includes inserting the infusion bag into the compartment of the support unit 101. The fifth step can include securing the infusion bag to the adhesive surface of the attachment surface by securing the infusion bag in the compartment by fastening the closing tabs with a hook-and-loop fastener, such as Velcro. A cannula is connected to the appropriate body portion of the patient, thereby providing a venous input to the patient's body. After closing the valve, the support unit 101 can be inflated using the pump 115.

[0055] By pumping air, both walls 102 of the support unit 101 are equally saturated with air and the pressure in the support unit 101 is controlled by a pressure gauge and control unit. As the pressure in the pressure infusion device 100 increases, the pressure entering the pressure gauge and limiter unit through a bore exerts an increased force on the bottom of the piston 121 and the seal, which initially prevents air from escaping and increasing pressure further.

[0056] Increasing pressure can push the piston 121 out of the housing 119 against the spring. The spring can be selected so that it approximately allows, for instance, as a pressure of 400 mmHg (53328,955 Pa), the lower pole of the plunger to raise so that a seal there reaches the lowest point of the milling cut. In this case, gas escapes to the outside of the gasket at the milling point and prevents further pressure increase. The milling length and spring force are set so that the piston is 400 mmHg (53328,955 Pa), so high that it reaches the milling mill and hence causes leakage to protect the system from overpressure.

[0057] The pressure infusion device 100 of the present invention can deliver therapeutic solutions to the human bloodstream through a cannula, needle, or catheter implanted, inserted, or drilled without the use of hydrostatic pressure due to gravitational attraction and with the appropriate (check valve and flow turbine). With the use of a fitted infusion tubing, the flow of the infusion fluid stops automatically and the check valve closes the vein, due to a stop valve that supplies a patient's vein at the end of dosing or when a malfunction occurs due to a malfunction or vacuum. The pressure infusion device 100 can be quickly attached to the human body by a suitable fastening procedure, allowing the patient to stand up and move without interrupting the administration of the solution.

[0058] All these benefits make the system particularly suitable for use in combat and on-site emergency patient care in low health care settings.
