[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually illustrative only and in no way limits the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0033] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments of the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations.

[0034] Unless otherwise specifically stated, the relative arrangements, numerical expressions and values of the components and steps described in these embodiments do not limit the scope of the present application. At the same time, it should be understood that for the sake of convenience of description, the sizes of the various parts shown in the drawings are not drawn in actual proportional relationship. Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the specification. In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0035] In the description of this application, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this application and simplifying the description. Without contrary explanation, these orientation words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation.

[0038] Please refer to Figures 1 to 3 , and now the all-round body positioning device based on plastic materials provided by the present utility model will be described. The all-round body positioning device based on plastic materials includes a lower plastic bag 10, an upper plastic bag 20 and a connecting component. The inside of the lower plastic bag 10 is suitable for accommodating foaming materials. The lower plastic bag 10 is suitable for being placed under the target object to form a structure matching the lower side of the target object after the foaming materials solidify; the inside of the upper plastic bag 20 is suitable for accommodating foaming materials. The upper plastic bag 20 is suitable for covering the upper side of the target object to form a structure matching the upper side of the target object after the foaming materials solidify. If head positioning is required, holes need to be opened at the positions corresponding to the mouth and nose on the upper plastic bag 20; one end of the connecting component is connected to the upper plastic bag 20, and is suitable for limiting the upper plastic bag 20 on the platform and enabling the lower plastic bag 10 and the upper plastic bag 20 to form a structure that wraps the target object all around.

[0039] It should be noted that the upper shaping bag 20 and the lower shaping bag 10 are bags made of materials with stable properties, suitable for sealing and resistant to chemical corrosion, such as corrosion-resistant nylon, fiber, plastic, etc.; the platform is an examination bed, a treatment bed, an operating table, etc.

[0040] During use, foaming materials are injected into the upper shaping bag 20 and the lower shaping bag 10, and the foaming materials are evenly distributed by pushing; then the lower shaping bag 10 is placed under the target object, the upper shaping bag 20 is wrapped around the target object, and the upper shaping bag 20 and the lower shaping bag 10 are made to closely adhere to the target object as much as possible by pushing. Then, the upper shaping bag 20 is fixed through the connecting component, and wait for the foaming materials to foam, expand and harden to complete the body position fixation of the target object; if necessary, then perform an examination or treatment on the target object; after the examination or treatment is completed, open the connecting component and put away the entire device for reuse next time.

[0041] The beneficial effect of the all-round body position positioning device based on shaping materials provided by the present utility model is: compared with the prior art, the all-round body position positioning device based on shaping materials provided by the present utility model can wrap any part of the human body through the cooperation of the upper shaping bag 20 and the lower shaping bag 10, and the inside is filled with foaming materials. During use, only need to wrap the upper shaping bag 20 and the lower shaping bag 10 around the target object, and after the foaming materials inside are cured, the target part of the target object can be fixed, without the need for preheating, and it is more convenient to use.

[0042] As Figure 1 and Figure 2 shown, in a specific implementation manner of the all-round body position positioning device based on shaping materials provided by the embodiment of the present utility model, it further includes a loading bag 40. The loading bag 40 is provided with two loading spaces for separately containing different components of the foaming materials.

[0043] Specifically, as Figure 1 and Figure 2 shown, in a specific implementation manner of the all-round body position positioning device based on shaping materials provided by the embodiment of the present utility model, a plurality of partition structures are provided in both the lower shaping bag 10 and the upper shaping bag 20. The partition structures divide the lower shaping bag 10 and the upper shaping bag 20 into multiple independent spaces; a loading bag 40 is provided in each independent space so that the foaming materials can be more evenly distributed in the lower shaping bag 10 and the upper shaping bag 20, avoiding concentration in one place due to the action of gravity.

[0044] It should be noted that the upper shaping bag 20 and the lower shaping bag 10 are hermetically arranged and divided into several regions through sealing; each region includes a group of loading bags 40, and the regions are isolated from each other without leakage.

[0045] The material of the loading bag 40 is a material with stable properties, suitable for sealing, and resistant to chemical corrosion, such as corrosion-resistant plastic. It can isolate and seal chemical raw material A and chemical raw material B from each other for a long time before they are mixed, and can cause chemical raw material A and chemical raw material B to mix under the action of appropriate external force. After the chemical raw material A and chemical raw material B are mixed to form an expanded foaming glue, the loading bag 40 will rupture and the mixed foaming glue will overflow.

[0046] The loading bag 40 contains chemical raw material A and chemical raw material B. The two materials are isolated from each other by sealing. Appropriate extrusion of the loading bag 40 can mix the two chemical raw materials. Chemical raw material A and chemical raw material B have the property of forming foaming glue after mixing. After the volume of the foaming glue expands, it overflows from the loading bag 40 in a fluid state and can be formed and solidified after a period of time. Chemical raw material A and chemical raw material B have the property of forming foaming glue with an increased volume after mixing. When they are just mixed, they are in a flowing liquid state and can become a formed solid in a short time for fixing the target object.

[0047] Furthermore, as Figure 1 and Figure 2 shown, in a specific implementation manner of the full-body position positioning device based on plastic materials provided in the embodiment of the present invention, a mixing channel 41 is provided on the loading bag 40. The outlet end of the mixing channel 41 communicates with the inside of the lower shaping bag 10 or the upper shaping bag 20, and the inlet end communicates with the loading space respectively. A diaphragm is provided at the part where the inlet end of the mixing channel 41 communicates with the loading space to mix different components of the foaming material in the loading space in the mixing channel 41 after the diaphragm is squeezed and broken. The middle part of the mixing channel 41 is one or more of a bending angle structure, an S-shaped structure, and a spiral structure.

[0048] It should be noted that when the method of using the foaming material to burst the loading bag 40 is adopted, the strength of the loading bag 40 needs to be relatively small, which will cause the loading bag 40 to be easily damaged during storage and transportation. Therefore, special protective measures are required. To avoid this problem, the loading bag 40 can be made of a relatively strong material, and a mixing channel 41 is provided on the loading bag 40. The outlet end of the mixing channel 41 communicates with the inside of the upper shaping bag 20 or the lower shaping bag 10, and the inlet end communicates with the loading space respectively. A diaphragm is provided at the part where the inlet end of the mixing channel 41 communicates with the loading space to mix different components of the foaming material in the loading space in the mixing channel 41 after the diaphragm is squeezed and broken. The diaphragm needs to be squeezed and broken by manual force, with higher strength and less likely to be damaged during storage and transportation.

[0049] Since there are no other materials in the upper shaping bag 20 and the lower shaping bag 10, and for the convenience of storage and access, the upper shaping bag 20 and the lower shaping bag 10 are usually completely flattened. If different components of the foaming material in the loading bag 40 are simultaneously extruded into the loading bag 40 or the upper shaping bag 20 and the lower shaping bag 10 at this time, it is necessary to manually knead the upper shaping bag 20 and the lower shaping bag 10 after extrusion to make them evenly mixed. Even so, it is difficult to achieve rapid and sufficient mixing; therefore, by providing a mixing channel 41 on the loading bag 40, different components of the foaming material can be forcibly and fully mixed during extrusion, not only the mixing will be relatively uniform, but also there is basically no need to manually knead the upper shaping bag 20 and the lower shaping bag 10 for mixing, which is beneficial to saving manpower and improving operation efficiency.

[0050] As Figure 1 and Figure 3 shown, in a specific embodiment of the full-body positioning device based on shaping materials provided by the embodiment of the present invention, it further includes a positioning pad 51 and a positioning structure 52. The positioning pad 51 is connected to the platform in a limited manner, and the positioning structure 52 is connected to the positioning pad 51 and is adapted to be clamped with the lower shaping bag 10.

[0051] It should be noted that the positioning structure 52 is a positioning protrusion or a positioning crossbar; specifically, when positioning and fixing the head and shoulder parts, the positioning protrusion is a headrest, and the lower shaping bag 10 is laid on the headrest so that after the foaming material in the lower shaping bag 10 solidifies, a groove matching the shape of the headrest is formed to facilitate positioning during the next use; when positioning and fixing other parts, the positioning structure 52 is multiple positioning crossbars. Several positioning crossbars are fixed at intervals on the positioning pad 51 and protrude from the surface of the positioning pad 51. The lower shaping bag 10 is laid on the crossbars so that after the foaming material in the lower shaping bag 10 solidifies, a groove matching the shape of the crossbars is formed to facilitate positioning during the next use.

[0052] Specifically, a plurality of first positioning holes 512 are provided on both sides of the positioning pad 51 along the length and width directions of the positioning pad 51. According to the different parts to be fixed, the two ends of the crossbar are inserted into the matching first positioning holes 512 to complete the positioning and fixing of the crossbar.

[0053] As Figure 1 and Figure 3 shown, in a specific embodiment of the full-body positioning device based on shaping materials provided by the embodiment of the present invention, the positioning pad 51 is of a flat plate structure, and a diversion groove 511 is formed on the positioning pad 51. The diversion groove 511 is of a mesh structure so that after the target object presses on the lower shaping bag 10, the foaming material in the lower shaping bag 10 can still flow to the bottom of the target object through the diversion groove 511.

[0054] As Figure 1 andFigure 3 As shown, in a specific implementation of the full-circle body positioning device based on plastic material provided in an embodiment of the utility model, a second positioning hole 513 is provided on the positioning pad 51, and the positioning pad 51 is fixed on the platform through the second positioning hole 513.

[0055] Specifically, positioning can be performed by setting a positioning pin on the platform and aligning the positioning pin with the second positioning hole 513. Bolts can also be used to pass through the second positioning hole 513 and be threadedly connected to the platform to fix the positioning pad 51 to the platform.

[0056] like Figure 1 and Figure 2 As shown, in a specific embodiment of the full-circle body positioning device based on molding material provided in an embodiment of the utility model, a cooling water pipe 60 is provided on the side of the lower molding bag 10 and the upper molding bag 20 facing the target object, so as to pass cooling water to cool the foaming material and prevent the heat generated during the foaming process of the foaming material from causing burns to the target object.

[0057] like Figure 3 and Figure 4 As shown, in a specific embodiment of the full-circle body positioning device based on molding material provided in an embodiment of the utility model, the connecting assembly includes two connecting mechanisms, which are respectively arranged on both sides of the platform width direction and connected to the upper molding bag 20 and the positioning pad 51.

[0058] The connecting mechanism includes a clamping strip 31, a slide rail 32 and a pressure block 33. The extension direction of the clamping strip 31 is parallel to the length direction of the platform. The clamping strip 31 is connected to the upper shaping bag 20, and a protrusion 311 is provided on the lower side of the clamping strip 31; the slide rail 32 is vertically arranged to the clamping strip 31 and is connected to the positioning pad 51. A plurality of clamping holes are provided on the upper side of the slide rail 32 at intervals along the length direction of the slide rail 32, and the protrusion 311 is suitable for being inserted into the clamping hole; the pressure block 33 is slidably matched with the slide rail 32, and a protruding pressure plate is provided on the front side of the pressure block 33, and the pressure plate is suitable for pressing the upper shaping bag 20 and the clamping strip 31.

[0059] It should be noted that the clamping strip 31 is fixedly connected to the upper shaping bag 20 , and the protrusion 311 protrudes downward and is inserted into the clamping hole.

[0060] In a specific embodiment, a receiving sleeve is provided at the edge of the upper shaping bag 20, the clamping strip 31 is inserted into the receiving sleeve, and the protrusion 311 protrudes downward from the receiving sleeve and is clamped into the clamping hole. In a specific embodiment, the connecting component is an existing quick clamp or clip.

[0061] In another specific embodiment, the connecting component includes a pressing plate and a fastener. The pressing plate is pressed on the upper side of the edge of the upper shaping bag 20, and then the pressing plate is fixed to the positioning pad 51 through the fastener, thereby clamping the edge of the upper shaping bag 20; the fastener is a component such as a bolt that can fix the pressing plate to the positioning pad 51.

[0062] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
