Description

Technical Field

[0001] This utility model belongs to the field of strap technology, specifically relating to a single-tube three-chamber independent pressure-controlled strap and system. Background Technology

[0002] Currently available three-chamber thrombosis treatment straps control the number of air chambers via trachea, with multiple tracheas controlling multiple air bags. For example... Figure 1 The diagram shows a three-chamber thrombosis treatment bandage. Each chamber is controlled by a separate trachea. The pressure in each chamber is controlled by an external device, and the pressure inside the chamber cannot be automatically controlled.

[0003] If only one trachea is pressurized with this type of three-chamber thrombosis treatment bandage, the other cavities cannot receive gas pressure and can only experience the working pressure of a single cavity. If treatment of more cavities is required, more tubes need to be inflated, making the bandage more complicated and the gas supply system more complicated. This makes it very inconvenient to use and does not achieve the working effect required by the three cavities. The external airway also becomes increasingly complicated. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a simple, single-pipe, three-chamber independent pressure control strap and system that features a simple structure, single-pipe air supply, and convenient connection.

[0007] The strap itself; and

[0008] A single-tube three-chamber airbag assembly is mounted on a strap body. The single-tube three-chamber airbag assembly includes an airbag. The airbag has a first partition layer and a second partition layer. The first partition layer and the second partition layer divide the inner cavity of the airbag into a first airbag cavity, a second airbag cavity, and a third airbag cavity. An inflation tube is connected to one side of the first airbag cavity. A quick connector is connected to the inflation tube. The first airbag cavity is connected to the second airbag cavity through a first guide tube. The first airbag cavity is connected to the third airbag cavity through a second guide tube.

[0026] Example 1

[0027] In this embodiment, a single-tube three-chamber independent pressure control strap and system is proposed. It uses a separate pipe for air intake, thereby achieving stepped pressure therapy. The overall connection to the external pipeline is simple and easy to connect, the overall volume is smaller, and the mold opening cost is correspondingly lower.

[0028] like Figure 2 and Figure 3As shown, in one embodiment of this utility model, the single-tube three-chamber independent pressure-controlled strap includes a strap body 1 and a single-tube three-chamber airbag assembly. The strap body 1 is prior art, and its structure is basically the same as that in the prior art. It can be set to a corresponding shape according to needs. In the prior art, the strap body 1 is generally a structure that is larger at the top and smaller at the bottom, and is then wrapped around the upper part of the lower leg for use. A Velcro 16 can be provided on one side of the strap body 1 so that this utility model can be wrapped around the lower leg for use. In addition to providing Velcro 16, This allows the invention to be used not only by wrapping it around the lower leg, but also by connecting it through a mutually cooperating buckle structure or a mutually cooperating magnetic structure. As the name suggests, the single-tube three-cavity airbag assembly consists of one air inlet tube and three cavities. Specifically, the single-tube three-cavity airbag assembly is mounted on the strap body 1. The single-tube three-cavity airbag assembly includes an airbag, within which there is a first partition layer 2 and a second partition layer 3. The first partition layer 2 and the second partition layer 3 divide the inner cavity of the airbag into a first airbag cavity 4, a second airbag cavity 5, and a third airbag cavity 6. Figure 2 and Figure 3For example, the first airbag cavity 4, the second airbag cavity 5, and the third airbag cavity 6 are arranged sequentially from bottom to top. The second partition layer 3 is located above the first partition layer 2. Both the first partition layer 2 and the second partition layer are welded lines, meaning that the first partition layer 2 and the second partition layer 3 are formed by braiding the welded lines of the airbag cavity and placed inside the airbag. An inflation tube 7 is connected to one side of the first airbag cavity 4, and a quick connector 8 is connected to the inflation tube 7. The inflation tube 7 can be a clean and transparent tube, and the quick connector 8 has a built-in sealing function that allows it to connect to external... The airbag is connected to an inflation device for inflation, and after inflation, it has a sealing function. The first airbag cavity 4 is connected to the second airbag cavity 5 through the first guide tube 11, and the first airbag cavity 4 is connected to the third airbag cavity 6 through the second guide tube 12. The airbag is equipped with a first pressure control valve 9 and a second pressure control valve 10. The first pressure control valve 9 is connected to the second airbag cavity 5, and the second pressure control valve 10 is connected to the third airbag cavity 6. The first guide tube 11 and the second guide tube 12 of this utility model are both high-precision guide tubes that can quickly... For airflow inflation, the first pressure control valve 9 and the second pressure control valve 10 of this utility model are both micro-nano-level pressure control valves, which can accurately control the pressure and exhaust through their own nano-level air holes. In the prior art, there are two main schemes for pressure control straps similar to this application (assuming three air bladder cavities). The first scheme is that each air bladder cavity is controlled by a separate air tube, and the pressure of the air bladder cavity is controlled by an external device. The air bladder cavity cannot automatically control the pressure inside the air bladder cavity. The second scheme is that the first air bladder cavity is connected to the second air bladder cavity, and the second air bladder cavity is connected to the third air bladder cavity. The gas enters the second air bladder cavity and the third air bladder cavity sequentially during inflation. When each air bladder cavity is controlled by a separate air tube, the pipeline is complex. In the second scheme, the efficiency of gas entering the third air bladder cavity is low. This application adopts a scheme that is different from the above two schemes. It retains the characteristic of efficient inflation of the third air bladder cavity and simple air path, and can accurately control the air pressure through the first pressure control valve and the second pressure control valve.

[0029] Please continue to refer to Figure 2 and Figure 3 In this invention, the pressure of the third airbag cavity 6 is less than the pressure of the second airbag cavity 5, and the pressure of the second airbag cavity 5 is less than the pressure of the first airbag cavity 4. Specifically, the third airbag cavity 6 is the proximal end (i.e., the end near the heart), the second airbag cavity 5 is the central end, and the first airbag cavity 4 is the distal end. In this invention, the pressure of the first airbag cavity 4 is 40 mmHg, the pressure of the second airbag cavity 5 is 35 mmHg, and the pressure of the third airbag cavity 6 is 30 mmHg. In actual use, one can experience a step-like pressure therapy effect.

[0030] Please refer to this again. Figure 3The strap body includes a first strap body layer 13, a second strap body layer 14, and a third strap body layer 15 connected sequentially from the inside out. The first strap body layer 13 is a Tricot layer or a spunlace nonwoven fabric layer, the second strap body layer 14 is a sponge layer, and the third strap body layer 15 is a velvet fabric layer. The first strap body layer 13, the second strap body layer 14, and the third strap body layer 15 are assembled and bonded together by flame bonding assembly.

[0031] This utility model also discloses a single-tube three-cavity independent pressure control strap system, including the aforementioned single-tube three-cavity independent pressure control strap.

[0032] It is understood that this utility model is intended for use on parts of the human body such as the lower leg. The various components of this utility model can be assembled and produced using a high-frequency welding process, achieving a level of sealing performance, tensile strength, and reliability comparable to a one-piece molding. When in use, gas enters through the inflation tube 7. Once the pressure in the first airbag cavity 4 reaches the set value, the gas is precisely introduced into the second airbag cavity 5 and the third airbag cavity 6 through the first guide tube 11 and the second guide tube 12, respectively. The second airbag cavity 5 and the third airbag cavity 6 can be precisely pressure-controlled and depressurized through the first pressure control valve 9 and the second pressure control valve 10, respectively, ultimately creating different pressure differences between the first airbag cavity 4, the second airbag cavity 5, and the third airbag cavity 6. The overall integration is high, the connection is convenient, the structure is simple, the size is small, the cost is low, and it is easy to wear.

[0033] It should be noted that the micro-nano pressure control valve used in this utility model patent is made of PVC sheet material through laser nanotechnology drilling, with the pore size reaching the nanometer level. Its pressure control accuracy reaches ±3mmHg. The micro-nano pressure control valve is integrally molded and pressed onto the airbag through high-frequency process. Its integration is high, and the presence of the pressure control valve cannot be felt on the outer surface. This makes the entire single-tube three-chamber independent pressure control strap smaller in size and simpler in structure, which is conducive to the miniaturization design of the product and further reduces the mold development cost.

[0034] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
