Description

Technical Field

[0001] This utility model relates to the technical field of infusion pressurization devices, and in particular to an airbag-type field infusion pressurization device. Background Technology

[0002] The airbag-type field infusion pressurization device is an infusion auxiliary device designed for special environments such as the field and battlefield. Its core function is to accelerate the infusion rate or ensure smooth infusion under low pressure conditions through the pressure of the airbag. It is suitable for infusion scenarios that require rapid fluid replenishment, emergency treatment, or in special body positions or low-pressure environments.

[0003] However, in field medical environments, due to limitations, traditional infusion methods often cannot meet the requirements of rapid infusion or the need to maintain a certain infusion pressure under specific conditions. For example, the air bladder of existing infusion pressure bags lacks structural constraints, and the inflation pressure is easily consumed by its own deformation rather than being converted into effective compression of the infusion bag. When a regular air bladder is inflated, in addition to the effective direction of vertical compression of the infusion bag, it will also bulge to the left and right sides. This expansion does not produce any pressurizing effect, but requires additional inflation to maintain the target pressure, resulting in reduced pressurization efficiency and hindering the goal of rapidly increasing infusion speed.

[0004] Therefore, this application provides an airbag-type field infusion pressurization device to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an airbag-type field infusion pressurization device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a pneumatic field infusion pressurization device, comprising a pneumatic body, and further comprising:

[0007] A rapid pressurization assembly is located on the outside of the airbag body. The rapid pressurization assembly includes a cylindrical restrictor connected to the outside of the airbag body. The airbag body has a rectangular structure. The cylindrical restrictor is connected to the airbag body and is arranged in an array on the airbag body.

[0008] Furthermore, both ends of the airbag body are connected with hook-and-loop fasteners, and the inner side of the hook-and-loop fasteners is provided with loop fasteners.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by controlling the position of the hook-and-loop fasteners on the loop fasteners and adjusting the distance between the two ends of the airbag body, it is beneficial to further improve the flexibility of the airbag body while fixing the airbag body to the outside of the infusion bag.

[0010] Furthermore, both the hook-and-loop hook and loop fasteners are double-sided.

[0011] The beneficial effects of adopting the above-mentioned further solution are: it facilitates the reinforcement of the connection between the hook-and-loop fasteners and the loop fasteners, and improves the stability of the airbag body fixed on the outside of the infusion bag.

[0012] Furthermore, the airbag body has a flexible tube connected to its interior, and the bottom of the flexible tube is connected to an inflatable ball.

[0013] The beneficial effect of adopting the above-mentioned further solution is that when the inflation ball is squeezed, the inflation ball quickly fills the interior of the airbag body with external air through the hose, pressurizing the interior and causing the airbag body to expand rapidly.

[0014] Furthermore, a branch tube is connected to one end of the hose near the airbag body, and a pressure gauge is connected to one end of the branch tube.

[0015] The beneficial effect of adopting the above-mentioned further solution is that it enables the pressure gauge to detect the pressure inside the airbag body, which facilitates pressure control.

[0016] Furthermore, a regulating valve is connected to one end of the hose near the inflatable ball, and a valve core is threaded onto the regulating valve.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by controlling the position of the valve core on the regulating valve, the air flow through the regulating valve can be adjusted, which facilitates precise control of the pressurized pressure.

[0018] Furthermore, a knob is connected to one end of the valve core.

[0019] The beneficial effects of adopting the above-mentioned further solution are: preventing slippage and facilitating stable and rapid rotation of the valve core via the knob.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. By incorporating a rapid pressurization component, the airbag body adopts a rectangular structure design, which enhances the versatility and flexibility of the airbag body. When gas is inflated into the airbag body, the cylindrical restrictor works in conjunction with the airbag body to limit the movement path of the gas, guiding the gas to be quickly delivered to the top along the cylindrical restrictor, thereby accelerating the pressurization efficiency and improving the uniformity of pressurization. The cylindrical restrictor can also limit the lateral expansion of the airbag body by its own structure, reducing ineffective deformation. This solves the problem that traditional airbags, due to the lack of structural constraints, are prone to having their inflation pressure easily consumed by their own deformation and cannot be effectively converted into the squeezing pressure on the infusion bag. This is conducive to achieving the goal of rapid pressurization and increasing the infusion rate. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-5 As shown, this utility model provides a technical solution: an airbag-type field infusion pressurization device, including an airbag body 1, and further comprising:

[0033] like Figures 1-2As shown, the rapid pressurization component 2 is located on the outside of the airbag body 1. The rapid pressurization component 2 includes a cylindrical restraint 21 connected to the outside of the airbag body 1. The airbag body 1 has a rectangular structure, and the cylindrical restraint 21 communicates with it. The cylindrical restraints 21 are arranged in an array on the airbag body 1. By setting the airbag body 1 into a rectangular structure, it is easier for the airbag body 1 to quickly wrap around and adapt to different types of infusion bags or bottles, which improves the versatility and flexibility of the airbag body 1. Furthermore, the cylindrical restraints 21 are fused to the airbag body 1, and the elasticity of the cylindrical restraints 21 is less than that of the airbag. The elasticity of the body 1, when gas is filled into the interior of the airbag body 1, the cylindrical limiter 21 cooperates with the airbag body 1 to limit the movement path of the gas, so that the gas is quickly delivered to the top along the cylindrical limiter 21, which accelerates the pressurization efficiency and uniformity. At the same time, the cylindrical limiter 21, through its own structure, restricts the lateral expansion of the airbag body 1, reduces ineffective deformation, and allows the inflation pressure to be more efficiently converted into the squeezing pressure on the infusion bag. This solves the problem that the airbag lacks structural constraints and the inflation pressure is easily consumed by its own deformation instead of being converted into effective squeezing of the infusion bag, which is conducive to achieving the purpose of rapid pressurization and increasing the infusion speed.

[0034] Furthermore, such as Figure 2 As shown, hook-and-loop fasteners 22 are connected to both ends of the airbag body 1. Loose-fitting fasteners 23 are provided on the inner side of the hook-and-loop fasteners 22. By fusing the hook-and-loop fasteners 22 to both ends of the airbag body 1 and adhering the loose-fitting fasteners 23 to the inside of the hook-and-loop fasteners 22, and making the length of the loose-fitting fasteners 23 greater than the length of the hook-and-loop fasteners 22, the distance between the two ends of the airbag body 1 can be adjusted by controlling the position of the hook-and-loop fasteners 22 adhering to the loose-fitting fasteners 23. This is beneficial for fixing the airbag body 1 to the outside of the infusion bag while further improving the flexibility of the airbag body 1.

[0035] Furthermore, such as Figure 3 As shown, both the hook-and-loop fastener 22 and the loop fastener 23 are double-sided structures. By making the hook-and-loop fastener 22 and the loop fastener 23 double-sided, it is easier to strengthen the connection between the hook-and-loop fastener 22 and the loop fastener 23, thereby improving the stability of the airbag body 1 fixed on the outside of the infusion bag.

[0036] Furthermore, such as Figure 4 As shown, a hose 24 is connected to the inside of the airbag body 1, and an inflation ball 25 is connected to the bottom of the hose 24. By welding the hose 24 between the inflation ball 25 and the airbag body 1, the inflation ball 25 is connected to the airbag body 1. When the inflation ball 25 is squeezed, the inflation ball 25 quickly inflates the airbag body 1 through the hose 24, pressurizing the inside and causing the airbag body 1 to expand rapidly.

[0037] Furthermore, such as Figure 4 As shown, one end of the hose 24 near the airbag body 1 is connected to a branch pipe 26, and one end of the branch pipe 26 is connected to a pressure gauge 27. By connecting the branch pipe 26 between the pressure gauge 27 and the hose 24, when the inflation ball 25 inflates the airbag body 1, some of the air is delivered to the inside of the pressure gauge 27 through the branch pipe 26, so that the pressure gauge 27 can detect the pressure inside the airbag body 1, which facilitates pressure control.

[0038] Furthermore, such as Figure 5 As shown, a regulating valve 28 is connected to one end of the hose 24 near the inflation ball 25. A valve core 29 is threaded onto the regulating valve 28. By rotating the valve core 29, the valve core 29 moves on the regulating valve 28 through the thread. By controlling the position of the valve core 29 on the regulating valve 28, the air flow through the regulating valve 28 can be adjusted, which facilitates precise control of the pressurization pressure.

[0039] Furthermore, such as Figure 5 As shown, a knob 3 is connected to one end of the valve core 29. The knob 3 is welded to the valve core 29 and a groove is opened on the knob 3. The knob 3 increases the friction with the hand through the groove to prevent slippage and facilitates stable and rapid rotation of the valve core 29 by the knob 3.

[0040] Working principle: such as Figures 1-5 As shown, first place the infusion bag on the airbag body 1, pull the airbag body 1 to wrap the infusion bag, attach the hook and loop fastener 23 to the inside of the loop fastener 22, and adjust the position of the loop fastener 22 to attach to the hook and loop fastener 23 so that the airbag body 1 tightly fixes the infusion bag inside. Rotate the knob 3, and the knob 3 drives the valve core 29 to move along the thread inside the regulating valve 28 to adjust the air flow. Then squeeze the inflation ball 25, and the inflation ball 25 quickly inflates the airbag body 1 through the hose 24 to pressurize it. When the airbag body 1 is inflated, the cylindrical restrictor 21 works with the airbag body 1 to limit the movement path of the gas, so that the gas is quickly delivered to the top along the cylindrical restrictor 21, which accelerates the pressurization efficiency and uniformity. At the same time, the cylindrical restrictor 21 restricts the lateral expansion of the airbag body 1 through its own structure, reduces ineffective deformation, and makes the inflation pressure more efficiently converted into the squeezing pressure on the infusion bag, which is conducive to achieving the purpose of rapid pressurization and increasing the infusion rate. Meanwhile, the pressure gauge 27 is connected to the cylindrical restrictor 21 through the branch pipe 26, thereby monitoring the flow rate inside the airbag body 1 in real time.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
