技术领域technical field
本发明涉及一种穿刺时对腕部进行保护的装置。The invention relates to a device for protecting the wrist during puncturing.
背景技术Background technique
静脉留置针、桡动脉穿刺等往往需要对腕部进行保护，例如静脉留置针，适用于儿童，但儿童对事物的认识不足，不懂得如何保护自己，手腕、手掌的活动相对随意而不能规避留置针在血管内的延伸，容易对自己产生伤害。Venous indwelling needles and radial artery puncture often require protection of the wrist, such as intravenous indwelling needles, which are suitable for children, but children do not know enough about things and do not know how to protect themselves. The movements of wrists and palms are relatively random and cannot avoid indwelling The extension of the needle in the blood vessel is easy to injure yourself.
再如桡动脉穿刺，所谓桡动脉，其在人体中先经肱桡肌与旋前圆肌之间，继而在肱桡肌腱与桡侧腕屈肌腱之间下行，绕桡骨茎突至手背，穿第1掌骨间隙到手掌，与尺动脉掌深支吻合构成掌深弓。桡动脉下段仅被皮肤和筋膜遮盖，是临床触摸脉搏的部位。动脉血气分析能客观反映呼吸衰竭的性质和程度，是判断患者有无缺氧和二氧化碳潴留的可靠方法。对指导氧疗、调节机械通气的各种参数以及纠正酸碱和电解质失衡均有很重要的意义。临床上常选用桡动脉穿刺采集动脉血标本做血液气体分析。Another example is the puncture of the radial artery. The so-called radial artery first passes between the brachioradialis muscle and the pronator teres in the human body, then descends between the brachioradialis tendon and the flexor carpi radialis tendon, wraps around the radial styloid process to the back of the hand, and passes through. From the first metacarpal space to the palm, it anastomoses with the deep palmar branch of the ulnar artery to form the deep palmar arch. The lower segment of the radial artery is only covered by the skin and fascia, and it is the place where the pulse is clinically felt. Arterial blood gas analysis can objectively reflect the nature and degree of respiratory failure, and is a reliable method to judge whether a patient has hypoxia and carbon dioxide retention. It is of great significance to guide oxygen therapy, adjust various parameters of mechanical ventilation, and correct acid-base and electrolyte imbalances. Clinically, radial artery puncture is often used to collect arterial blood samples for blood gas analysis.
由于桡动脉相对比较细，穿刺难度比较大，要求患者手臂自然平放，因操作者左手食指需触摸桡动脉搏动，无法绷紧穿刺部位的皮肤，使穿刺部位皮肤松弛，进针时患者明显感到穿刺部位疼痛，有的患者因无法耐受，甚至拒绝穿刺；因不能很好地固定桡动脉，穿刺时桡动脉易滑动，致使反复穿刺或容易穿刺失败。因此，为辅助桡动脉穿刺，需要对腕部进行固定。Because the radial artery is relatively thin, the puncture is difficult, and the patient’s arm is required to be laid flat naturally. Because the operator’s left index finger needs to touch the radial artery pulse, the skin at the puncture site cannot be tightened, and the skin at the puncture site is loose. The puncture site is painful, and some patients even refuse the puncture because they cannot tolerate it; because the radial artery cannot be fixed well, the radial artery is easy to slip during puncture, resulting in repeated puncture or easy puncture failure. Therefore, to assist radial artery puncture, the wrist needs to be immobilized.
目前医院普遍采用例如架手板进行腕部或者手掌的固定，所谓架手板其主体实质上是一块硬质板，在架手板不足时可以使用例如银行卡之类的硬质板代替。使用时将架手板或者类似的硬质板置于手掌或者手腕合适位置，然后用胶带进行架手板的固定。At present, the hospital generally adopts such as a hand board to fix the wrist or palm. The main body of the so-called hand board is actually a hard board. When the hand board is insufficient, a hard board such as a bank card can be used instead. When in use, place the hand frame or a similar hard board at a suitable position on the palm or wrist, and then use adhesive tape to fix the hand frame.
架手板形制相对简单，不能有效的与人体生理结构相匹配，也往往与相应的操作不相匹配。The shape of the handboard is relatively simple, and it cannot effectively match the physiological structure of the human body, and often does not match the corresponding operation.
中国专利文献CN202446578U公开了一种静脉留置针防脱落装置，它配有一个手套，可以套在患者手上，然后在辅助例如腕带、袖带进行其可靠固定。其主体欠缺刚性，本质上主要用来防止留置针的脱落，而不能避免腕部、手掌的翻转。Chinese patent document CN202446578U discloses a device for preventing venous indwelling needles from falling off. It is equipped with a glove that can be placed on the patient's hand, and is then reliably fixed by assisting such as wristbands and cuffs. Its main body lacks rigidity, and is mainly used to prevent the fall-off of the indwelling needle in essence, but cannot avoid the turning of the wrist and palm.
中国专利文献CN202168991U则公开了一种输液用保护手套，其结构与CN202446578U所公开的方案相近，其区别主要在于保护手套的手掌面采用一块硬质的底板。这种手套状的结构因个体的差异造成其适用性相对较差，且均不能对腕部进行有效保护。Chinese patent document CN202168991U discloses a protective glove for infusion, which is similar in structure to the scheme disclosed in CN202446578U, the main difference being that the palm surface of the protective glove adopts a hard base plate. The applicability of this glove-like structure is relatively poor due to individual differences, and none of them can effectively protect the wrist.
中国专利文献CN102379688B则公开了一种动脉穿刺留置针固定装置，该固定装置通过一中部为平板两侧带有弧形结构的前臂托板再配合固定带实现腕部的固定，其本质上类同于架手板，其区别之处在于增加了一些辅助结构。单纯就手腕的固定来说，其仍然采用在手臂方向上平直的板进行固定，适应性偏差。Chinese patent document CN102379688B discloses a fixation device for arterial puncture indwelling needles. The fixation device realizes the fixation of the wrist through a forearm support plate with a flat plate in the middle and an arc structure on both sides, and cooperates with a fixation belt. Compared with the prototype, the difference is that some auxiliary structures are added. As far as the fixation of the wrist is concerned, it is still fixed with a straight plate in the direction of the arm, and the adaptability is deviated.
形制相对简单的固定装置应用比较广泛，再如中国专利文献CN201631841U公开的医用输液固定板，也是采用一块具有一定刚度的板（芯板），再通过定位带扣合。整体而言，当前采用这类形制的输液/穿刺针固定装置比较普遍，缺陷也基本相同，前文中基本进行了说明。Fixing devices with relatively simple shapes are widely used. Another example is the medical infusion fixing plate disclosed in Chinese patent document CN201631841U, which also uses a plate (core plate) with a certain rigidity, and is fastened by a positioning belt. On the whole, the current infusion/puncture needle fixation devices using this type of shape are relatively common, and the defects are basically the same, which are basically explained in the previous text.

具体实施方式Detailed ways
参照说明书附图1所示的一种腕部保护套，是其展开结构，另外需要注意，所说的“套”包含但并不表示全部都是覆盖圆周的套，否则图示的例如相对较长的束带7就失去意义，通过束带7实现“套”大小的调整，以满足不同轴径手臂的使用。Referring to the wrist protection sleeve shown in Figure 1 of the specification, it is its unfolded structure. In addition, it should be noted that the so-called "cover" includes but does not mean that all of them cover the circumference of the sleeve, otherwise the illustrated example is relatively small. Long belt 7 just loses meaning, realizes the adjustment of " cover " size by belt 7, to satisfy the use of different shaft diameter arms.
图中“套”主体，可见于图中的基体3所包围手臂的范围，应涵盖手臂正面和两个侧面，手臂背面可部分地被涵盖，有利于例如“束带7”长度的调整，以适应不同的患者。The main body of the "sleeve" in the figure can be seen in the range of the arm surrounded by the base body 3 in the figure. It should cover the front and two sides of the arm, and the back of the arm can be partially covered, which is beneficial for example. adapt to different patients.
自然，成人与儿童之间手臂大小差别很大，本方案不涉及全年龄段的适应性，可以制作成例如幼童、少年、青年等各个分段的型号，因此，不必强调其最广泛的适应性。Naturally, there is a big difference in arm size between adults and children. This program does not involve the adaptability of all age groups. It can be made into models of various segments such as toddlers, teenagers, and youth. Therefore, it is not necessary to emphasize its widest adaptability sex.
在基础的参考系中，匹配手心手背，手心侧表示正面，手背侧标示背面。In the basic frame of reference, match the palm and the back of the hand, with the palm side representing the front and the back of the hand representing the back.
在基础的参考系中，图1中束带孔12与束带7所限定的两边之间构成为向内，反之，则为向外，若为内侧，为所限定边的例如图中基体3左边沿的右侧。In the basic frame of reference, the two sides defined by the belt hole 12 and the belt 7 in FIG. Right side of the left edge.
参见图1-3所示的结构，所限定的腕部保护套设有一个基体3，该基体3的主体为软质材料制作的矩形片。Referring to the structure shown in Figs. 1-3, the defined wrist protector is provided with a base body 3, and the main body of the base body 3 is a rectangular piece made of soft material.
所使用的软质材料优选植物纤维，例如棉、麻，成本低，透气性好。The soft materials used are preferably plant fibers, such as cotton and hemp, which are low in cost and good in air permeability.
所使用的软质材料粗还可选为其他亲水性材料，主要是亲水性纤维，例如前述的棉麻属于亲水性纤维材料。The soft material used can also be selected from other hydrophilic materials, mainly hydrophilic fibers, for example, the aforementioned cotton and hemp belongs to hydrophilic fiber materials.
关于所述亲水性纤维（hydrophilic fiber），是指回潮率大于4.5%、吸湿性较强的纤维，例如棉或者麻。此类纤维的大分子链上具有一定数量的较强极性的集团（如-OH、 -NH 、C=O等），能与水分子形成氢键结合。其无定形区和结晶区的边缘部分较大，分子结构较为疏松，水分子容易深入纤维表面的微小空隙内。The hydrophilic fiber refers to a fiber with a moisture regain greater than 4.5% and strong hygroscopicity, such as cotton or hemp. There are a certain number of strong polar groups (such as -OH, -NH, C=O, etc.) on the macromolecular chain of this type of fiber, which can form hydrogen bonds with water molecules. The edges of the amorphous and crystalline regions are relatively large, and the molecular structure is relatively loose, so water molecules can easily penetrate into the tiny gaps on the surface of the fiber.
亲水性纤维种类繁多，因此，适应于本方案的亲水性纤维选材范围也很广。并且公知的所有天然纤维如蚕丝、兔毛、驼毛、棉、麻等等，都属于亲水性纤维。人造纤维中的再生纤维如粘胶纤维其化学成分与棉纤维完全相同，所以也属于亲水性纤维。而所有合成纤维如涤纶、锦纶、氨纶、丙纶、氯纶等等，都属于非亲水性纤维、也叫做疏水性纤维。There are many kinds of hydrophilic fibers, therefore, the selection range of hydrophilic fibers suitable for this scheme is also very wide. And all known natural fibers such as silk, rabbit hair, camel hair, cotton, hemp, etc., all belong to hydrophilic fibers. Regenerated fibers in man-made fibers such as viscose fibers have exactly the same chemical composition as cotton fibers, so they are also hydrophilic fibers. And all synthetic fibers such as polyester, nylon, spandex, polypropylene, polyvinyl chloride, etc., are non-hydrophilic fibers, also called hydrophobic fibers.
亲水性纤维的典型特点之一是其编织物能够吸水并能够及时的将所吸的水很快的排出，这也是为什么穿着亲水性纤维的衣服舒适性更好，原因也在于亲水性纤维所制造的纺织品，能及时散发人体排出的水汽，使服用者感觉舒适，没有发闷、不透气的不良感受。One of the typical characteristics of hydrophilic fibers is that their fabrics can absorb water and quickly discharge the absorbed water in a timely manner, which is why clothes wearing hydrophilic fibers are more comfortable, and the reason is also the hydrophilicity. The textiles made of fiber can dissipate the water vapor discharged from the human body in time, so that the wearer feels comfortable without feeling stuffy or airtight.
基体3优选植物纤维，比如棉布或者麻布制作，为了增加强度，可以含有网状的结构层，以不影响透气为前提。The substrate 3 is preferably made of plant fibers, such as cotton cloth or linen cloth, and may contain a net-like structural layer in order to increase strength, on the premise of not affecting air permeability.
在一些实施例中，还可以采用以棉或者麻为衬底的多层结构的基体3结构，结构层的其他部分可以制作孔洞，以提高透气性。In some embodiments, a multi-layer matrix structure with cotton or linen as the substrate can also be used, and holes can be made in other parts of the structural layer to improve air permeability.
在前述的内容中已经指出，“套”大多数的应用中并不构成完全的周向包围结构，而具有暴露的部分，例如匹配手背的部分暴露出来，不影响固定，但具有很好的透气性。It has been pointed out in the foregoing that the "sleeve" does not form a complete circumferential surrounding structure in most applications, but has exposed parts, such as the part matching the back of the hand, which does not affect the fixation, but has good ventilation sex.
应当注意，所谓的矩形片并非几何意义上的矩形，而表示宏观的矩形，例如六角头螺栓，并不表示其是严格意义上的六棱体。例如图中，矩形的四个顶角圆角化处理。It should be noted that the so-called rectangular sheet is not a rectangle in the geometric sense, but a macroscopic rectangle, such as a hexagon head bolt, does not mean that it is a hexagonal body in the strict sense. For example, in the figure, the four corners of the rectangle are rounded.
在图1中所示的结构中，主体相对的一对边，例如图中所示的左右两边构造为连接边，用以匹配连接以使主体形成套。In the structure shown in FIG. 1 , a pair of opposite sides of the main body, such as the left and right sides shown in the figure, are configured as connecting sides for mating connection so that the main body forms a sleeve.
关于两连接边的连接，可以是自体的连接，例如采用按扣的连接方式，基体3部分含有弹性体，也可以满足调整套围的需要。Regarding the connection of the two connecting sides, it can be a self-connection, such as a snap button connection, and the base body 3 contains elastic body, which can also meet the needs of adjusting the circumference of the sleeve.
连接边上还可以附加其他连接结构，连接边作为连接基体，附加的连接结构用于实现连接。例如图1中所示的束带7和束带孔12的结构。Other connection structures can also be added to the connection edge, the connection edge is used as a connection matrix, and the additional connection structure is used to realize the connection. For example, the structure of the belt 7 and the belt hole 12 shown in FIG. 1 .
图中还含有一个定位结构，也就是在一连接边的一端内侧预定距离处开有一拇指孔11，图中上下表示的就是连接边的延伸方向，所说的一端指的是在该延伸方向上的端部。内侧则表示为两连接边之间的“内”，通常理解上，在此处“内侧”不超出两边距从该连接边起的三分之一处，以匹配构造“套”的结构条件下，匹配小臂正面和两侧。The figure also contains a positioning structure, that is, a thumb hole 11 is opened at a predetermined distance inside one end of a connecting edge. What is shown up and down in the figure is the extending direction of the connecting edge. the end of. The inner side is expressed as the "inner" between the two connecting sides. It is generally understood that the "inner side" here does not exceed one-third of the distance between the two sides from the connecting side, so as to match the structural conditions of the construction of the "sleeve". , matching forearm front and sides.
这样，当拇指孔11佩戴到手指上时，会形成一个在“套”轴向的约束，同时也会产生周向的约束，而限定住其他部分的位置，例如下面所提到支撑板等。In this way, when the thumb hole 11 is worn on the finger, an axial constraint on the "sleeve" will be formed, and a circumferential constraint will also be generated to limit the position of other parts, such as the support plate mentioned below.
关于支撑板，在图1中表示为由板体4和定位头8构成的板，整体表现为为刚性的条形板，整体类似于常规的架手板，其设置目的也是常规架手板在本方案中的变形，所起的作用可直接匹配架手板。Regarding the support plate, it is shown as a plate composed of a plate body 4 and a positioning head 8 in Fig. 1. The overall performance is a rigid strip plate, which is similar to a conventional hand frame as a whole, and its setting purpose is also that the conventional hand frame is in this plan. The deformation in the frame can directly match the hand plate.
其设置方式如图1所示，平行于两连接边，并固定设置在两连接边之间的主体中部，或者说位于基体3的中间位置，使用时匹配小臂和手掌的正面，起到支撑作用。Its setting method is shown in Figure 1. It is parallel to the two connecting sides, and is fixedly arranged in the middle of the main body between the two connecting sides, or in the middle of the base body 3. When used, it matches the front of the forearm and the palm to provide support. effect.
进一步地，在图1中所示的结构中，还设有第二定位槽6，为轴线平行于连接边的直槽口，如图1中所示，这种直槽又叫腰形槽，在图中，与拇指孔11相对而分居在支撑板的两边，使用时匹配小臂的侧面，不延伸到手掌部位，仅延伸到手腕关节处。Further, in the structure shown in Figure 1, there is also a second positioning groove 6, which is a straight notch whose axis is parallel to the connecting edge, as shown in Figure 1, this straight groove is also called a waist groove, In the figure, it is opposite to the thumb hole 11 and separated on both sides of the support plate. When in use, it matches the side of the forearm and does not extend to the palm of the hand, but only to the wrist joint.
在此先行描述一下粘扣结构，粘扣全称是粘扣带，又称魔术贴（HOOk&LOOP），在一些领域中还被称为子母扣，是衣服上常用的一种连接辅料，分子母两面，一面是细小柔软的纤维，圆毛（LOOP)，另一面是较硬带钩的刺毛（HOOK)。一般的衣服HOOK在上面。Let me first describe the Velcro structure here. The full name of Velcro is Velcro, also known as Velcro (HOOk&LOOP). In some fields, it is also called mother-in-law button. , one side is small and soft fiber, round hair (LOOP), and the other side is harder bristle with hook (HOOK). General clothes HOOK on top.
本方案中的工作面表示圆毛面和刺毛面之一，逆工作面则表示与其性质相反的面，例如工作面为圆毛面，则逆工作面就表示刺毛面。The working surface in this scheme represents one of the round rough surface and the bristle surface, and the reverse working surface then represents the surface opposite to it.
基于粘扣的结构，其中该第二定位槽6的槽底设有粘扣的第一逆工作面，这样就能够匹配工作面17，可以相互粘合或者脱开。Based on the Velcro structure, the bottom of the second positioning groove 6 is provided with the first reverse working surface of the Velcro, so that the working surface 17 can be matched, and can be bonded or separated from each other.
进一步地，定位带18，其一带面为粘扣的工作面17，另一带面为光面16，见图3，其中在定位带18长度方向上部分工作面与第一逆工作面配合，例如图3中所示的逆性工作面19，那么相对地，兜顶部14与兜底部相对的面也是逆性工作面。这样，在图3所示的定位带18所示的结构中，兜底部20和兜顶部14能够同时与定位带18配合。Further, the positioning belt 18 has a working surface 17 whose one surface is a hook and loop fastener, and the other belt surface is a smooth surface 16, as shown in Fig. 3, wherein a part of the working surface cooperates with the first reverse working surface in the length direction of the positioning belt 18, for example As for the reverse working surface 19 shown in FIG. 3 , then relatively, the surface opposite to the pocket top 14 and the pocket bottom is also a reverse working surface. In this way, in the structure shown in the positioning belt 18 shown in FIG. 3 , the pocket bottom 20 and the pocket top 14 can cooperate with the positioning belt 18 at the same time.
进而，如图3所示，配置定型板15，长度短于定位带18而置于光面16上，并在该定型板15的两端，由于比定型板15长，余出的定位带18从两端包绕定型板15，而使部分工作面17逆向于第二定位槽6，也就是朝向兜顶部14，这样，当包绕完成后，上下两个部件，也就是兜顶部14和兜底部20就能够对定位带18形成可靠定位，进而约束定型板15的位置。And then, as shown in Figure 3, dispose shaping plate 15, length is shorter than positioning band 18 and be placed on smooth surface 16, and at the two ends of this shaping plate 15, owing to longer than shaping plate 15, remaining positioning band 18 Wrap the shaping plate 15 from both ends, and make part of the working surface 17 reverse to the second positioning groove 6, that is, towards the top of the pocket 14, like this, after the wrapping is completed, the upper and lower parts, that is, the top of the pocket 14 and the bottom of the pocket The portion 20 can form a reliable positioning for the positioning belt 18, thereby constraining the position of the shaping plate 15.
基于前述的结构，定位带18的调整非常方便，只需要包绕完成，将其放在例如第二定位槽6的长度方向上的预定位置，压合即可形成可靠定位。Based on the above-mentioned structure, the adjustment of the positioning belt 18 is very convenient. It only needs to be wrapped and placed at a predetermined position in the length direction of the second positioning groove 6, and pressed to form a reliable positioning.
因此，关于兜顶部14，如图3所示，与第二定位槽6配合形成兜，而将定位带18和定型板15纳入，且兜顶部14与第二定位槽6相对的面为第二逆工作面。Therefore, regarding the top 14 of the pocket, as shown in Figure 3, it cooperates with the second positioning groove 6 to form a pocket, and the positioning belt 18 and the shaping plate 15 are incorporated, and the surface opposite to the top 14 of the pocket is the second positioning groove 6. Inverse working surface.
本方案中的调整涉及两个方面，一个是周面的调整，即基体围绕所形成的套的大小的调整，以匹配手臂粗细；再一个方面是定型板的调整，适应不同的手臂长度。通过对这两个方面的调整，适应不同的患者。The adjustment in this scheme involves two aspects, one is the adjustment of the peripheral surface, that is, the adjustment of the size of the sleeve formed around the base body to match the thickness of the arm; the other is the adjustment of the shaping plate to adapt to different arm lengths. By adjusting these two aspects, it can adapt to different patients.
当然，如前文所述，此处的调整并不是要求一个型号的腕部保护套适应所有的患者，这是不现实的，或者说代价太大。Of course, as mentioned above, the adjustment here does not require one type of wrist protector to be suitable for all patients, which is unrealistic or too expensive.
在图1所示的结构中，所述支撑板的下端与拇指孔11在该端的边沿平齐，使用时，支撑板能够延伸到手心位置，相应于手掌的生理结构，在此处即可形成可靠的支撑。In the structure shown in Figure 1, the lower end of the support plate is flush with the edge of the thumb hole 11 at this end. When in use, the support plate can extend to the palm of the hand, corresponding to the physiological structure of the palm, where it can be formed. Reliable support.
在一些实施例中，在图1所示的结构中，支撑板还可以继续往下所示的方向延伸，覆盖整个手掌心，但相对而言会影响透气性，不建议使用。在优选的实施例中采用图1所示的结构，即前文所述的与拇指孔11在下端的边沿平齐。In some embodiments, in the structure shown in FIG. 1 , the support plate can also continue to extend in the direction shown below, covering the entire palm, but relatively speaking, it will affect the air permeability, so it is not recommended to use. In a preferred embodiment, the structure shown in FIG. 1 is adopted, that is, the aforementioned one is flush with the edge of the thumb hole 11 at the lower end.
在图1所示的结构中，支撑板通过袋式结构固定在基体3，图中开有预制定位槽9，但可以预见的是，不设置预制定位槽9也可以完成定位板的固定，可以直接利用图中所示的盖片5缝纫在基体3上形成袋，用以将支撑板纳入实现固定。In the structure shown in Figure 1, the support plate is fixed on the base body 3 through a pocket structure, and there is a preset positioning groove 9 in the figure, but it is foreseeable that the fixing of the positioning plate can also be completed without setting the preset positioning groove 9, which can Directly use the cover sheet 5 shown in the figure to sew to form a pocket on the base body 3, to incorporate the support plate for fixing.
在一些实施例中还可以在支撑板上形成预制孔，通过这些预制孔例如使用线将其固定在基体3上。In some embodiments it is also possible to form prefabricated holes in the support plate, through which it is fixed to the base body 3, for example using threads.
在优选的实施例中，所述支撑板包括条形平整的板体和在其长度方向上匹配拇指孔11处设置的匹配手掌的曲面板，直接匹配掌型，具有较好的匹配度，佩戴条件下相对也比较舒适。In a preferred embodiment, the support plate includes a strip-shaped flat plate body and a curved plate that matches the palm of the thumb hole 11 in its length direction, directly matches the palm shape, and has a better matching degree. Relatively comfortable under conditions.
应当注意，佩戴时，曲面的向掌心隆起。It should be noted that when worn, the curved surface bulges toward the palm.
在前述的内容中指出，支撑板采用常规的架手板也可以满足使用要求。It is pointed out in the foregoing content that the support plate can also meet the requirements of use by using a conventional hand frame.
参见说明书附图1,图中在基体3上还设有配型结构，具体是在主体上形成有匹配曲面板的预制定位槽9，配合方式可见于图3下部，该种结构也有利于支撑板的固定。Refer to the accompanying drawing 1 of the specification. In the figure, there is also a matching structure on the base 3. Specifically, a predetermined positioning groove 9 matching a curved panel is formed on the main body. The matching method can be seen in the lower part of Figure 3. This structure is also conducive to supporting Fixing of the board.
为有利于设计制作，所述曲面板为一球面板，球面板的半径不宜过小，以不小于10厘米为宜。To facilitate design and manufacture, the curved panel is a spherical panel, and the radius of the spherical panel should not be too small, preferably not less than 10 centimeters.
图3中，所述兜顶部14的一侧边缝纫在第二定位槽6的一侧槽壁上边而形成第一连接点，由此形成翻开结构，有利于定型板15的定位操作，且减少了操作时的固定点。In Fig. 3, one side of the pocket top 14 is sewn on one side of the second positioning groove 6 to form a first connection point, thereby forming an open structure, which is beneficial to the positioning operation of the shaping plate 15, and Fixed points during operation are reduced.
加以配合的，在兜顶部14的另一侧边或者两端至少一处设置有与第二定位槽6可拆连接的第二连接点，以形成可靠连接。To cooperate, at least one of the other side or two ends of the pocket top 14 is provided with a second connection point detachably connected with the second positioning groove 6 to form a reliable connection.
在图3所示的结构中，图中的逆性工作面19没有完全占据兜底部20的上表面，余出的部分可以构造连接点。当然连接点也可以采用粘扣结构形成，相应地，逆性工作面19可以全部占据兜底面20的上表面，在兜顶面14上留出部分表面用以形成相对的工作面，例如匹配兜底部20的两端位置。In the structure shown in FIG. 3 , the reverse working surface 19 in the figure does not completely occupy the upper surface of the pocket bottom 20 , and the remaining part can be used as a connection point. Of course, the connection point can also be formed by using a Velcro structure. Correspondingly, the reverse working surface 19 can completely occupy the upper surface of the bottom surface 20 of the pocket, and leave a part of the surface on the top surface 14 of the pocket to form an opposite working surface, such as matching the bottom of the pocket. Both ends of the part 20.
还可以构造出例如匹配兜底部20的周缘位置设置连接点，形成一圈的粘扣结构。It is also possible to construct, for example, matching the peripheral position of the pocket bottom 20 to set connection points to form a circle of Velcro structure.
优选地，形成所述第二连接点的结构为粘扣结构，操作非常方便。Preferably, the structure forming the second connection point is a Velcro structure, which is very convenient to operate.
具体的，第二连接点设置在兜顶部14的另一侧边，且匹配的粘扣结构为：Specifically, the second connection point is set on the other side of the top 14 of the pocket, and the matching Velcro structure is:
在该另一侧边向外延伸有第一粘扣面，并在基体3上与之相对的面上形成有与第一粘扣面性质相反的第二粘扣面。A first fastening surface extends outward from the other side, and a second fastening surface opposite in nature to the first fastening surface is formed on the surface of the base 3 opposite thereto.
在一些优选的实施例中，在基体3上还设有第一定位槽1，该第一定位槽1为轴线平行于第二定位槽6的直槽口，且比第二定位槽6短而与拇指孔11在同一轴线上；In some preferred embodiments, a first positioning groove 1 is also provided on the base body 3, the first positioning groove 1 is a straight notch whose axis is parallel to the second positioning groove 6, and is shorter than the second positioning groove 6 and On the same axis as the thumb hole 11;
相应地，还为第一定位槽1定位带和定型板，设置方式与第一定位槽1相同。Correspondingly, the belt and the shaping plate are also positioned for the first positioning groove 1 , and the setting method is the same as that of the first positioning groove 1 .
这样两块定型板分别匹配手臂的两侧，形成更加可靠的定位。In this way, the two shaping plates match the two sides of the arm respectively, forming a more reliable positioning.
在图1所示的结构中，第一定位槽1的位置与拇指孔11并不在一轴线上，而是更靠近左侧的连接边，在使用时，第一定位槽1会偏置于小臂背面，相对形成更加可靠的定位，只不过覆盖较多的皮肤表面，影响透气性。In the structure shown in Figure 1, the position of the first positioning groove 1 and the thumb hole 11 are not on the same axis, but closer to the connecting edge on the left side. When in use, the first positioning groove 1 will be offset to a small The back of the arm relatively forms a more reliable positioning, but it covers more skin surface, which affects air permeability.
为避免对皮肤产生较多的摩擦，所述拇指孔11为在第一定位槽1方向延伸的条形孔，且与虎口配合的一端为大端，另一端为小端，大拇指的一侧能够暴露出来，不会产生较大的附加载荷，佩戴舒适性更好。In order to avoid more friction on the skin, the thumb hole 11 is a strip-shaped hole extending in the direction of the first positioning groove 1, and the end that matches the tiger's mouth is the big end, the other end is the small end, and one side of the thumb is It can be exposed without generating a large additional load, and the wearing comfort is better.
当拇指孔11为圆形时，由于拇指的走向并非与“套”的壁面垂直，佩戴时，即便是基体3为柔性体，也会产生一定的附加载荷，而影响配戴舒适性，当然，本方案也不排除圆形拇指孔的使用。When the thumb hole 11 is circular, since the direction of the thumb is not perpendicular to the wall of the "sleeve", when worn, even if the base body 3 is a flexible body, a certain additional load will be generated, which will affect the wearing comfort. Of course, This solution also does not preclude the use of circular thumb holes.
在优选的实施例中，如图1所示，用于连接边连接的结构为：In a preferred embodiment, as shown in Figure 1, the structure used to connect edge connections is:
在一连接边上形成有束带孔12；A belt hole 12 is formed on one connecting edge;
在另一连接边上连接有束带7。A drawstring 7 is connected on the other connecting edge.
其中束带7的两个面可以采用粘扣的结构，穿过束带孔后，直接反绕粘接，操作非常方便。Wherein the two surfaces of the drawstring 7 can adopt the structure of hook and loop, after passing through the drawstring hole, directly rewind and bond, and the operation is very convenient.
