Detailed Description
The embodiment of the application provides an active pneumatic pressure treatment device and a control method thereof, which are used for realizing pressure treatment on the surface of a human body covered by the device, increasing the action of a muscle pump and promoting the compliance of blood circulation and pressure treatment.
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For the sake of understanding, the following describes a specific device in an embodiment of the present application, referring to fig. 1, an embodiment of an active pneumatic pressure treatment device in an embodiment of the present application is applied to a pressure sock, and the device may specifically include:
a pressure sock 101 with a fabric base, a pneumatic system 102, a control system 103;
the pressure sock 101 comprises an outer knitted layer and an inner knitted layer, and one or more built-in/embedded/detachable air bags;
the pneumatic system 102 is pneumatically connected to the air bag;
the control system 103 is used to control the pneumatic system through which the bladder is inflated and/or deflated to cause the compression stocking 101 to provide a controlled dynamic pressure dose.
In this embodiment, applied to a compression sock, the device includes: a pressure sock 101 with a fabric base, a pneumatic system 102, a control system 103; the pressure sock 101 comprises an outer knitted layer and an inner knitted layer, and one or more embedded/detachable air bags; the pneumatic system 102 is pneumatically connected to the air bag; the control system 103 is used to control the pneumatic system through which the bladder is inflated and/or deflated to cause the compression stocking 101 to provide a controlled dynamic pressure dose. The control system can control the pneumatic system to inflate and/or deflate the air bag so as to enable the pressure sock to provide controllable dynamic pressure dose, pressure treatment on the surface of the human body covered by the inner fabric can be achieved, muscle pump action is increased, and blood circulation and pressure treatment compliance are promoted.
As a preferred implementation, the compression stockings are made by three-dimensional knitting, weaving, non-woven forming or sewing or gluing, or by a combination of one or more of these techniques, to form a material with high and low elastic differences and conforming to the surface curvature and the elastic stiffness of the structure of the human body.
In this embodiment, the inner fabric (the skin-contacting layer, i.e., the higher elastic fabric layer (long stretch layer)) and the outer fabric (the skin-away layer, i.e., the lower elastic fabric layer (short stretch layer)) are made of different densities and knitting structures, and have different elasticity and stiffness formed between the inner and outer layers, so as to realize the outside-in "directional pneumatic pressure" generated by the inflation of the air bag, so as to transmit the pneumatic pressure to the soft tissues of the legs more effectively, and the outer fabric does not generate or generates a small amount of limited stretch deformation.
In addition, the knitted layer can form a semi-surrounding or fully-surrounding structure relative to the legs according to actual wearing or treatment needs, and a local pressure feeding mode or a circular centripetal pressure feeding mode is realized. In a semi-enclosed structure, the outer fabric layer will employ layers of heterogeneous knit in different directions around the leg, avoiding localized high pressure. For example, at the shin bone in the front of the leg, high curvature, with only a few muscles, local high pressure will cause discomfort, or ischemia and tissue damage, while at the back of the leg, muscle dominated, rounded contours (low curvature), and deep veins packed in the muscle mass, the higher compression force helps promote muscle pump function and venous return. According to the Laplace principle, for the semi-enclosed partial pressure mode, the heterogeneous knitted layer is designed to enhance the stiffness of the rear muscles of the legs while relatively reducing the stiffness of the front parts of the legs, improving the comfort and safety of the pressure fabric in wearing. Local pressure application, and specific pressure dose and pressure application mode can also be applied along the distribution path of the greater saphenous vein or the lesser saphenous vein. In general, the outer fabric will be specifically designed to provide elasticity and stiffness properties that meet biomechanical and ergonomic requirements based on the anatomy of the human leg, soft tissue elasticity and compression requirements, and the weave pattern of the fabric at various leg locations.
As a preferred implementation, referring to fig. 2, the inner fabric comprises a higher elastic fabric and a higher elastic thermoplastic polyurethane film, shown as a first layer and a second layer, and the outer fabric comprises a lower elastic thermoplastic polyurethane film and a lower elastic fabric, shown as a third layer and a fourth layer, the higher elastic thermoplastic polyurethane film and the lower elastic thermoplastic polyurethane film forming the airbag.
As a preferred implementation, the airbag is made of a material comprising one or more of a thermoplastic polyurethane film or silicone rubber or an elastic polyamide or polyimide or polyester elastic knit material; the combination of the outer and inner knitted layers and the airbag is by lamination, sewing, bonding and/or welding; the pressure socks are used for forming the air bags with controllable shapes in a three-dimensional multi-layer and multi-cavity bonding or weaving mode; the air bag can be independently or integrally placed into a knitting cavity formed by the outer knitting layer and the inner knitting layer.
The inner and outer knitted fabric layers can adopt different three-dimensional knitted structures (gaskets, tucks, jacquard patterns and the like) to form single-sided or multi-sided heterogeneous knitted pressure sock base layers with different stiffness, tension, elasticity and thickness, and the single-sided or multi-sided heterogeneous knitted pressure sock base layers are placed on human soft tissues with specific surface curvature, hardness and focus distribution;
the air bag can be cut into different geometric shapes by laser so as to regulate and control the mechanical property and pressure delivery dosage of the air bag;
the balloon can pressurize the local tissue wrapped by the compression sock, or form a gradient progressive, or other multi-modal selectable pressure dose delivery, size and distribution;
the pressure socks can be integrated with integrated bandages, support strips, buckles, zippers or other accessories to form a customizable and multifunctional composite pressure device for medical use, daily use and sports, and is used for preventing and treating different parts of a human body, wearing modes (a pull-on type, a wrapping type and the like) and symptoms.
As a preferred implementation, the inner and outer fabrics are joined by means of a hot press/high cycle.
In this embodiment, knitting the fourth layer can form a high stiffness pressure layer through a special knitting process of specially designed fine elastic yarn, providing a pushing force to squeeze and act on the human body from the shallow layer to the deeper layer (as shown in fig. 3). On its inside, a layer of a less elastic thermoplastic polyurethane film (TPU) is designed as a third layer to form a laminated pressure tight wall. The two layers are used as the outer layers of the air bag, and the consistent elasticity is kept so as to meet the aerodynamic change of pressure dosage control.
In this embodiment, to form an embedded textile plenum beneath the outer layer but maintain tactile comfort, a 3D knit fabric designed using 3D knitting techniques can be used as the functional double-sided knit layer of the first layer, the 3D knit fabric also having the advantage of allowing "breathability" beneath the plenum, improving moisture egress. On the outside of the first layer, another TPU film with high elasticity is designed as a second layer, which is laminated to the flat surface of the third layer by hot pressing, high frequency or other techniques. The laminated first and second layers would be configured as an inner layer of the chamber that is bonded to an outer layer to form a fabric-based air-tight chamber.
In this embodiment, a prefabricated pressure bladder may also be inserted into the double knit garment: the two-layer garment substrate will be designed to cover a specific area and the inner layer will be comfortable and smooth. The outer layer of the garment fabric is the high stiffness pressure layer (fourth layer in fig. 2) and the inner 3D base layer (first layer in fig. 2) is the soft layer. When the prefabricated pressure air bag is inserted into the knitted garment, the rigidity difference between the outer layer and the inner layer can provide pushing force to press deeper tissues of the human body. The preformed plenum may be of any suitable material, such as polyurethane, or any combination thereof.
Further, the following explains the compression socks in the present embodiment by three examples:
first, the inner and outer fabric layers of the compression sock 101 comprise four layers, from inside to outside, a first layer of relatively low elasticity soft and comfortable fabric such as a mesh, a second layer of relatively high elasticity thermoplastic polyurethane film, a third layer of relatively low elasticity thermoplastic polyurethane film and a fourth layer of uniform relatively stiff breathable fabric. The TPU thermoplastic polyurethane films 2 and 3 are used for preparing the air bag in a hot pressing, high frequency or other advanced preparation process mode, and the air bag is reheated and pressed or sewed between the first knitted fabric layer and the fourth knitted fabric layer to form the heterogeneous air bag. The lower stretch soft and comfortable fabric of this example consisted of 75-85% nylon and 15-25% lycra or spandex. The fabric can be knitted into mesh cloth with different designs including thickness, mesh shape, flexibility and the like to meet the requirements. In this embodiment, the lower elasticity knitted garment acts directly as the fourth layer of the outer fabric of the pressure bladder. The active pressure garment structure has the advantages that the active pressure garment structure is simple to manufacture, the pressure air bag can be compounded with any garment base body, and certain pressure is effectively applied to the body surface of a human body.
Second, the heterogeneous pressure airbag was manufactured in the same manner as in the first example except that the laser-cut textured polyurethane film finishing high elastic fabric was used as the fourth layer of the heterogeneous pressure airbag. The active pneumatic pressure garment prepared by the method has the advantages of portability, attractive appearance and fashion, can apply pressure with different strengths to different parts of a human body according to requirements, can be prepared at low cost, and can be conveniently prepared into an active pneumatic pressure garment device capable of realizing effective pressure distribution on the surface of the human body to the maximum extent. The outer layer of the laser cutting pattern type polyurethane film composite high-elasticity fabric in the embodiment is made of 75-85% of nylon and 15-25% of lycra or other spandex. Is prepared by a knitting method. The thickness of the polyurethane film is 0.2-0.3mm, and the laser cutting pattern units can be hexagonal and can also be expanded into any shape. The tread shape and cell size can be adjusted as needed for the application of pressure. A wide range of shapes and sizes are selected to cover the TPU film to achieve the high compression effect. Wherein, the hot pressing conditions of the pattern type TPU film in the embodiment are as follows: temperature: 140-150 ℃, time: 20-50s, pressure: 6 Pa.
Thirdly, the procedure is the same as the second example except that the bandage-type large modulus fabric kit is used to replace the laser-cut pattern-type polyurethane film finishing elastic fabric as the fourth layer of the heterogeneous pressure air bag to enhance the pressing effect of the outer layer of the pressure air bag. The active pressure garment prepared by the method has the function of being detached at any time, and is comfortable and soft to wear when people walk. The pressure can be quickly assembled when the pressure is needed, so that the pressure application effect is achieved. The bandage-type large modulus fabric kit may be designed as shown in fig. 4. The fabric was prepared in the same manner as in the first example, but is not limited thereto.
As a preferred solution, the bladder is used to cover 10% to 100% of the area of the compression sock for creating a selectable dynamic pressure of 0 to 250 mm hg;

in this embodiment, the pressure sock designed by the air bag structure prepared in the above embodiments can realize the multi-mode inflation and deflation process of a single air bag or a plurality of air bags. Typically, the pressures achievable by these balloons range from 0 to 250 mm hg and can be applied to work under a variety of conditions to ameliorate various leg discomfort symptoms as shown in figure 5. The recommended treatment range depends on the diagnostic result and the patient basic condition, but is usually 20 to 50 mmhg. The available timing periods vary from a few seconds to a few minutes, with the total treatment time per treatment session varying from 10 minutes to 3 hours, and may depend on the diagnosis and condition of the patient, particularly during the implementation of the protocol.
In this embodiment, particularly in the pressure sock of the device, the air bags formed by the inner layer fabric and the outer layer fabric can be one or more, and the control system is used for controlling the process of inflating and/or deflating the air bags through the opening and closing of the pneumatic connecting valves.
