Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a body fixation belt. Background Technology

[0002] In current medical and nursing practices, when patients with endotracheal intubation exhibit agitation or delirium, the most common clinical practice is to restrain their limbs with straps.

[0003] However, this method only restricts the movement of the patient's limbs and is insufficient to effectively immobilize the upper body. When patients are agitated or delirious, their twisting and struggling are significant, and the restraints cannot fully control these abnormal movements. This can lead to significant twisting of the patient's body, causing the tubing to be pulled, twisted, or even dislodged due to the patient's movements, thus affecting the treatment outcome. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, one objective of this utility model is to provide a body fixation belt that can effectively restrict body movement and prevent patients from twisting their bodies excessively, which could cause the tubing to be pulled, twisted, or even dislodged due to the patient's body movements, thereby ensuring the patient's treatment effect.

[0006] To achieve the above objectives, this utility model proposes a body fixation strap, comprising: a chest pad, wherein shoulder straps, underarm straps and abdominal straps are respectively provided on both sides of the chest pad, and the width and / or length of the chest pad can be extended or shortened for adjustment; and a back pad, wherein multiple through holes are provided on the back pad, and the free ends of the shoulder straps, the underarm straps and the abdominal strap are respectively inserted through the corresponding through holes.

[0007] In addition, the body immobilization belt proposed in the application may also have the following additional technical features:

[0008] Specifically, the breast pad includes a first spliced ​​fabric, a second spliced ​​fabric, two first connecting parts, and two first extensions. The first spliced ​​fabric and the second spliced ​​fabric are detachably spliced ​​together by the two first connecting parts, and there is a cutout area between the two first connecting parts. The two first extensions are respectively arranged below the corresponding first connecting parts, and one end of the first extension is connected to the first spliced ​​fabric, and the other end of the first extension is fixed to the second spliced ​​fabric. When the first spliced ​​fabric and the second spliced ​​fabric are spliced ​​together, the first extension is folded in a U-shape. When the first spliced ​​fabric and the second spliced ​​fabric are not spliced ​​together, the first extension is unfolded along the width direction of the breast pad.

[0009] Specifically, both the first and second spliced ​​fabrics include a first sub-spliced ​​fabric, a second sub-spliced ​​fabric, a second connecting component, and a second extension. The first and second sub-spliced ​​fabrics are detachably spliced ​​together via the second connecting component. The second extension connects the first and second sub-spliced ​​fabrics along the width of the breast pad. When the first and second sub-spliced ​​fabrics are spliced ​​together, the second extension is folded in a U-shape. When the first and second sub-spliced ​​fabrics are not spliced ​​together, the second extension is unfolded along the length of the breast pad.

[0010] Specifically, the two second connecting components in the first and second spliced ​​fabrics are distributed on both sides of the hollowed-out area.

[0011] Specifically, the shoulder strap and the underarm strap are respectively disposed on the first sub-panel fabric, and the shoulder strap extends along the length direction of the chest pad. The abdominal belt is disposed on the second sub-panel fabric, and the underarm strap and the abdominal belt both extend along the width direction of the chest pad.

[0012] Specifically, the first connecting component and the second connecting component are zippers or snap fasteners.

[0013] Specifically, the first connecting component includes multiple sets of first buckle structures arranged along the length direction of the breast pad. Each set of first buckle structures includes a first fixing strap and multiple first fixing buckles. The first splicing fabric has multiple first fixing buckles arranged at equal intervals along the width direction of the breast pad. The second splicing fabric has the first fixing strap. The first fixing strap has multiple first fixing holes. The first fixing buckles can be detachably snapped into the corresponding first fixing holes.

[0014] Specifically, the second connecting component includes multiple sets of second buckle structures arranged in the width direction of the breast pad. Each set of second buckle structures includes a second fixing strap and multiple second fixing buckles. The first sub-sew fabric has multiple second fixing buckles arranged at equal intervals along the length direction of the breast pad. The second sub-sew fabric has a second fixing strap with multiple second fixing holes. The second fixing buckles can be detachably snapped into the corresponding second fixing holes.

[0015] Specifically, both the first fixing buckle and the second fixing buckle include a ball head and a limiting rod. The ball head is interference-fitted with the first fixing hole or the second fixing hole, and the limiting rod is adapted to the first fixing hole or the second fixing hole.

[0016] Specifically, a fixing ring is provided in the through hole, and the free end of the shoulder strap, the underarm strap, or the abdominal strap passes through the fixing ring.

[0017] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0018] (1) Through the synergistic action of shoulder straps, axillary straps, abdominal straps, chest pads, and back pads, the patient's upper body can be effectively fixed and restrained.

[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0035] The body fixation strap of this utility model embodiment will now be described with reference to the accompanying drawings.

[0036] like Figure 1 As shown, the body fixation strap of this utility model embodiment may include a chest pad 1 and a back pad 5.

[0037] The chest pad 1 is equipped with shoulder straps 2, underarm straps 3, and abdominal straps 4 on both sides. The width and / or length of the chest pad 1 can be adjusted. Specifically, the width and length of the chest pad 1 can be adjusted independently, or both can be adjusted simultaneously. This flexible adjustment method effectively changes the coverage area of ​​the chest pad 1, thus adapting to people of different body types. Whether it's obese adults or small children, the coverage area of ​​the chest pad 1 can be adjusted according to individual needs to meet diverse usage requirements and expand its applicability.

[0038] The back pad 5 has multiple through holes 50. The free ends of the shoulder straps 2, underarm straps 3 and abdominal straps 4 are respectively inserted through the corresponding through holes 50, and their free ends can be fixed to the hospital bed or stretcher.

[0039] It should be noted that the multiple through holes 50 can be arranged along the width of the back pad 5, and multiple rows can be set; at the same time, these through holes 50 can also be arranged along the length of the back pad 5, and multiple rows can also be set. In this way, after the size of the chest pad 1 is adjusted according to actual needs, the shoulder straps 2, underarm straps 3, and abdominal straps 4 can select suitable corresponding through holes 50 from the many through holes 50, so that the back pad 5 and the chest pad 1 together form a restrictive space that fits the patient's body shape, significantly improving the fixation effect on the body.

[0040] Specifically, in practice, this body fixation strap is used in conjunction with the limb binding straps. First, the back pad 5 is placed under the patient's back, and then the chest pad 1 is laid flat on top of the patient's chest. Subsequently, the shoulder straps 2, axillary straps 3, and abdominal straps 4 are passed through the corresponding holes 50 on the back pad 5 in sequence and secured to the hospital bed or stretcher.

[0041] Among them, shoulder strap 2 plays the role of limiting the position of the shoulder, closely conforming to the shoulder contour and effectively restricting the range of shoulder movement; underarm strap 3 passes through the patient's underarm and plays the role of limiting the position of the chest; abdominal strap 4 stabilizes and limits the abdomen, further restricting the movement of the abdomen.

[0042] The combined action of shoulder straps 2, axillary straps 3, abdominal straps 4, chest pads 1, and back pads 5 effectively restricts and fixes the patient's upper body. This fixation method significantly limits the range of motion of the body, preventing the tubing from being stretched, twisted, or even dislodged due to large twists of the patient's body. In this way, reliable support is provided for the patient's treatment, ensuring the successful achievement of therapeutic effects.

[0043] In one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the breast pad 1 includes a first spliced ​​fabric 10, a second spliced ​​fabric 11, two first connecting parts 12, and two first extension parts 13.

[0044] The first splicing fabric 10 and the second splicing fabric 11 are detachably spliced ​​together by two first connecting parts 12. There is a hollow area 14 between the two first connecting parts 12. Two first extension parts 13 are respectively arranged below the corresponding first connecting parts 12. One end of the first extension part 13 is connected to the first splicing fabric 10, and the other end of the first extension part 13 is fixed to the second splicing fabric 11. When the first splicing fabric 10 and the second splicing fabric 11 are spliced ​​together, the first extension part 13 is folded in a U-shape. When the first splicing fabric 10 and the second splicing fabric 11 are not spliced ​​together, the first extension part 13 is unfolded along the width direction of the chest pad 1.

[0045] It should be noted that the first extension 13 is made of a flexible material, such as cloth or leather.

[0046] Specifically, refer to Figure 3 When the width of the breast pad 1 needs to be adjusted, the splicing state of the first spliced ​​fabric 10 and the second spliced ​​fabric 11 can be changed by adjusting the connection state of the first connecting component 12. When the first spliced ​​fabric 10 and the second spliced ​​fabric 11 are spliced, the first extension 13 will be folded in a U-shape, and the width of the breast pad 1 is relatively narrow at this time; while when the first spliced ​​fabric 10 and the second spliced ​​fabric 11 are not spliced, that is, when the first spliced ​​fabric 10 and the second spliced ​​fabric 11 are separated from each other, the first extension 13 will unfold along the width direction of the breast pad 1, thereby extending the width of the breast pad 1 to suit different people.

[0047] In one embodiment of this utility model, such as Figure 1 As shown, both the first splicing fabric 10 and the second splicing fabric 11 include a first sub-splicing fabric 100, a second sub-splicing fabric 101, a second connecting component 15, and a second extension (not shown in the figure).

[0048] The first sub-panel fabric 100 and the second sub-panel fabric 101 are detachably spliced ​​together via the second connecting member 15. The second extension connects the first sub-panel fabric 100 and the second sub-panel fabric 101 along the width direction of the chest pad 1. When the first sub-panel fabric 100 and the second sub-panel fabric 101 are spliced ​​together, the second extension is folded in a U-shape. When the first sub-panel fabric 100 and the second sub-panel fabric 101 are not spliced ​​together, the second extension is unfolded along the length direction of the chest pad 1. It can be understood that the connection form of the second extension can refer to... Figure 2The connection form of the first extension part 13.

[0049] Specifically, when the length of the breast pad 1 needs to be adjusted, the splicing state of the first sub-spanning fabric 100 and the second sub-spanning fabric 101 can be changed by altering the connection state of the second connecting component 15. When the first sub-spanning fabric 100 and the second sub-spanning fabric 101 are spliced, the second extension portion will be folded in a U-shape, at which point the length of the breast pad 1 is relatively narrow. When the first sub-spanning fabric 100 and the second sub-spanning fabric 101 are not spliced, that is, when the first sub-spanning fabric 100 and the second sub-spanning fabric 101 are separated from each other, the second extension portion will unfold along the length direction of the breast pad 1, thereby extending the length of the breast pad 1 to suit different groups of people.

[0050] Furthermore, such as Figure 1 As shown, the two second connecting parts 15 in the first splicing fabric 10 and the second splicing fabric 11 are distributed on both sides of the hollow area 14.

[0051] In the above scheme, such as Figure 1 As shown, two second connecting parts 15 are respectively disposed on both sides of the width direction of the hollow area 14, while two first connecting parts 12 are distributed on both sides of the length direction of the hollow area 14, and they remain in a non-contacting state with each other. The advantage of this layout is that when it is necessary to separate the first splicing fabric 10 from the second splicing fabric 11, the second connecting parts 15 will not interfere with it; similarly, when the first sub-splicing fabric 100 is separated from the second sub-splicing fabric 101, the first connecting parts 12 will not cause any impact. Through this reasonable design, the adjustment operation of the breast pad 1 in the width or length direction can be carried out smoothly.

[0052] In one embodiment of this utility model, such as Figure 1 As shown, shoulder strap 2 and underarm strap 3 are respectively set on the first sub-spanning fabric 100, and shoulder strap 2 extends along the length direction of chest pad 1. Abdominal strap 4 is set on the second sub-spanning fabric 101, and both underarm strap 3 and abdominal strap 4 extend along the width direction of chest pad 1.

[0053] In the above scheme, the shoulder strap 2, the underarm strap 3, and the abdominal strap 4 extend in different directions to form multi-angle fixation, which can increase the fixation effect. At the same time, the shoulder strap 2 extends along the length direction, which can increase the contact area with the shoulder, thereby improving the restraint effect on the shoulder. The underarm strap 3 and the abdominal strap 4 both extend along the width direction of the chest pad 1, which can improve the restraint effect on the chest and abdomen.

[0054] In one embodiment of this utility model, such as Figure 1As shown, the first connecting component 12 and the second connecting component 15 are zippers. The zippers can be used to separate and splice the first splicing fabric 10 and the second splicing fabric 11, or to separate or splice the first sub-splicing fabric 100 and the second sub-splicing fabric 101.

[0055] For example, the following description uses a zipper as an example of the first connecting component 12. When the zipper is pulled, the zipper head causes the teeth on the first and second spliced ​​fabrics 10 and 11 to engage and disengage. When the teeth on the first and second connecting components 12 and 15 are engaged, the first and second spliced ​​fabrics 10 and 11 are in a spliced ​​state; when the zipper head is pulled, causing the teeth on the first and second connecting components 12 and 15 to disengage, the first and second spliced ​​fabrics 10 and 11 are in a separated state. In this separated state, the first extension portion 13 unfolds along the width direction of the breast pad 1, thereby extending the width of the breast pad 1.

[0056] In another embodiment of this utility model, the first connecting component 12 and the second connecting component 15 are snap fasteners. The connection between the snap fasteners can realize the separation and splicing between the first splicing fabric 10 and the second splicing fabric 11, or the separation or splicing between the first sub-splicing fabric 100 and the second sub-splicing fabric 101.

[0057] For example, the first connecting component 12 is described below as a male and female buckle. The male buckle can be fixed on the first spliced ​​fabric 10, and the female buckle can be fixed on the second spliced ​​fabric 11. Through the connection between the male and female buckles, the splicing and fixing between the first spliced ​​fabric 10 and the second spliced ​​fabric 11 can be realized. When the male and female buckles are separated, the first spliced ​​fabric 10 and the second spliced ​​fabric 11 can be separated, thereby extending the width of the chest pad 1.

[0058] In another embodiment of this utility model, such as Figure 4 and Figure 5 As shown, the first connecting component 12 includes multiple sets of first buckle structures 120 arranged along the length of the breast pad 1. Each set of first buckle structures 120 includes a first fixing strap 1200 and multiple first fixing buckles 1201.

[0059] The first splicing fabric 10 has multiple first fixing buckles 1201 arranged at equal intervals along the width direction of the chest pad 1, and the second splicing fabric 11 has a first fixing strap 1200. The first fixing strap 1200 has multiple first fixing holes 12000, and the first fixing buckle 1201 can be detachably snapped into the corresponding first fixing hole 12000.

[0060] In the above solution, by engaging the first fixing hole 12000 on the first fixing strap 1200 with the first fixing buckle 1201 at different positions, the unfolded width of the chest pad 1 can be flexibly changed, achieving multi-level width adjustment. This multi-level adjustment method greatly enhances the adaptability of the chest pad 1 to people of different body types. Whether it is a large adult or a small child, a suitable width setting can be found. This allows for precise adaptation to the body shapes of different people, enabling the chest pad 1 to fit more tightly and stably on the patient's body, thereby significantly improving the fixation effect on the patient's body.

[0061] In one embodiment of this utility model, such as Figure 4 As shown, the second connecting component 15 includes multiple sets of second buckle structures 150 arranged in the width direction of the breast pad 1. Each set of second buckle structures 150 includes a second fixing strap 1500 and multiple second fixing buckles 1501.

[0062] The first sub-span fabric 100 has multiple second fixing buckles 1501 arranged at equal intervals along the length of the chest pad 1, and the second sub-span fabric 101 has a second fixing strap 1500 with multiple second fixing holes. The second fixing buckles 1501 can be detachably snapped into the corresponding second fixing holes (not shown in the figure).

[0063] In the above solution, by engaging the second fixing hole on the second fixing buckle 1501 with the second fixing buckle 1501 at different positions, the unfolded length of the chest pad 1 can be flexibly changed, achieving multi-level length adjustment. This multi-level adjustment method greatly enhances the adaptability of the chest pad 1 to people of different body types. Whether it is a robust adult or a petite child, a suitable width setting can be found. This allows for precise adaptation to the body shapes of different people, enabling the chest pad 1 to cover the patient's body more tightly and stably, thereby significantly improving the fixation effect on the patient's body.

[0064] In one embodiment of this utility model, such as Figure 5 As shown, both the first fixing buckle 1201 and the second fixing buckle 1501 include a ball head 1202 and a limiting rod 1203. The ball head 1202 is interference-fitted with the first fixing hole 12000 or the second fixing hole, and the limiting rod 1203 is adapted to the first fixing hole 12000 or the second fixing hole.

[0065] In the above scheme, the ball head 1202 is interference-fitted with the first fixing hole 12000 or the second fixing hole. During assembly, medical staff only need to accurately align the ball head 1202 with the first fixing hole 12000 or the second fixing hole, and then apply appropriate pressure. The ball head 1202 can then smoothly engage with the corresponding first fixing hole 12000 or the second fixing hole, easily achieving a quick connection.

[0066] It is worth mentioning that the ball head 1202 plays a limiting role in this design. When the body sways, it can effectively prevent the first fixing strap 1200 or the second fixing strap 1500 from disengaging from the limiting rod 1203. This ingenious design greatly improves the stability of the first fixing strap 1200 or the second fixing strap 1500 after installation, thereby ensuring the effectiveness of the chest pad 1 in being fixed.

[0067] In one embodiment of this utility model, such as Figure 1 As shown, a fixing ring 51 is provided in the through hole 50, and the free ends of the shoulder strap 2, underarm strap 3 or abdominal strap 4 are inserted through the fixing ring 51.

[0068] In the above solution, the fixing ring 51 can cover and protect the inner wall of the through hole 50, thereby avoiding direct friction between the inner wall of the through hole 50 and the shoulder strap 2, underarm strap 3 or abdominal strap 4. This prevents the through hole 50 from expanding due to long-term friction between the shoulder strap 2, underarm strap 3 or abdominal strap 4 and the through hole 50. In this way, the through hole 50 can always maintain a good shape, thereby ensuring that it plays a stable and accurate guiding and limiting role for the shoulder strap 2, underarm strap 3 or abdominal strap 4.

[0069] In summary, the body fixation strap of this application embodiment can effectively restrict body movement and prevent patients from twisting their bodies significantly, which could cause the tubing to be pulled, twisted, or even dislodged due to the patient's body movements, thereby ensuring the patient's treatment effect.
