M282663 八、新型說明： 【新型所屬之技術領域】 本新型是有關於一種散壓支撐裝置，特別是指一種符合使用者 軀體輪廓之散壓支撐裝置。 【先前技術】 人體的表皮與肌肉細胞長期受壓，將會因血液循環不良而壞 死。對於一般感覺神經、運動神經與肌肉之收縮機能良好的正常人 而言，若有十餘分鐘不稍活動而使部分軀體受壓而有麻痒感時，就 I 會因不舒服而自然更換姿勢，此種反應即使在睡夢中都少有停歇。 然而，對於感覺神經及/或運動神經受損的肢障者、痲瘋病患、中風 患者、甚至植物人，如第一圖所示，躺臥的病患在諸如後腦的枕骨 91、脊椎92、尾椎93、手肘94等部分皮膚與肌肉受到持續壓力而 壓迫該處微血管，使部分區域貧血時，無法正常感受、或是無法正 常驅動肢體變更姿勢，改變受壓位置，兩小時後肌肉產生缺血，六 小時肌肉就會發生變性而壞死。而且皮膚耐壓的程度較肌肉好，當 他人注意到皮膚開始紅腫時，内部的肌肉早已潰爛而形成壓瘡(或俗 > 麵瘡）。 近來部分醫療儀器設備業者注意到相關問題，提出如第二圖所 不之座塾(或床塾)8，藉由多組橡膠材質充氣囊81之密集陣列式排 列’且充氣囊81下方分別以閥門相通，使各充氣囊81間氣體可相 互流動，而各自因應不同部位壓力大小，調整充氣囊内氣體量分 佈，以提供各自獨立之支撐；但因單一充氣囊受下壓力後，不僅會 被向下壓爲、並可能同時朝側向歪斜，所以充氣囊必須緊密排列、 相互依靠，使用者臀部接觸座墊8部分肌膚悶熱潮濕，造成使用者 另方面的不適。 M282663 另於我國新型專利公告第295839及第趣38號「座塾之改良 結構」’如第三圖所示，是分別在上下兩片基板7卜72上，形成彼 此相向對應之實心向下凸柱73、中空向上凸柱74，如第四圖所示，M282663 VIII. Description of the new type: [Technical field to which the new type belongs] The new type relates to a bulk pressure support device, in particular to a bulk pressure support device that conforms to the contours of a user's body. [Previous technology] The human body's epidermis and muscle cells are under long-term compression, which will cause necrosis due to poor blood circulation. For normal people with good contraction of sensory nerves, motor nerves, and muscles, if they do n’t move for more than ten minutes and some parts of the body are compressed and they feel itchy, they will naturally change their posture due to discomfort. This reaction rarely stops even in dreams. However, for patients with impaired sensory and / or motor nerves, patients with leprosy, stroke, or even vegetative, as shown in the first figure, lying patients such as the occipital 91, spine 92, The tail and vertebrae 93, elbow 94 and other parts of the skin and muscles are under continuous pressure to compress the microvessels. When anemia is caused in some areas, they can't feel normally, or they can't drive the limbs to change their posture and change the compression position. Two hours later, muscles are produced. Ischemia, muscle degeneration and necrosis occur within six hours. Moreover, the pressure of the skin is better than that of the muscles. When others notice that the skin starts to swell, the internal muscles have already ulcerated and formed pressure ulcers (or vulgar > facial ulcers). Recently, some medical instrument and equipment manufacturers have noticed related problems, and have proposed seat blocks (or bed sheets) 8 which are not shown in the second figure, and are arranged in a dense array of multiple sets of rubber-made inflatable bladders 81. The valves communicate with each other so that the gas in each of the inflatable bladders 81 can flow with each other, and each of them adjusts the distribution of the gas volume in the inflatable bladders to provide independent support according to the pressure of different parts. It is pressed downward and may be tilted sideways at the same time, so the inflatable bladders must be closely arranged and rely on each other. The skin of the user's buttocks touching the seat cushion 8 is hot and humid, causing another discomfort for the user. M282663 In addition, China's new patent publication No. 295839 and No. 38 "improved structure of the seat" as shown in the third figure, are formed on the upper and lower substrates 7 and 72 respectively, forming a solid downward convex corresponding to each other Post 73, hollow upward convex post 74, as shown in the fourth figure,

When a user sits on the upper substrate 71 ±, as shown by the dotted line, the top 74 of the hollow upward projection 74 at the position where the pressure is greater will be forced to deform to the side, so that the downward projection 73 there will descend; and the user will leave the seat After the pressure is removed, the elasticity returns to its original state. However, when the upward convex pillars 73 are stretched and deformed by the pressure, the downward stroke of the downward convex pillar M cannot correspond to the magnitude of the pressure. In other words, although the location where the movement is greatly reduced is lower than other parts—some, However, the lowered height is actually not as good as needed; in addition, the thief's strength is uneven in various parts of the seat cushion, and the top end of the upwardly protruding column 74 where the force is large is prone to permanent lightness, fatigue, and opening. Elastic elasticity must be discarded as a whole; on the other hand, in Chulin, the compression deformation of each upward convex pillar 74 is approximately equal to the difference in patient weight, taking into account the needs of difficult patients. The "Combined Breathable Massage Dual-use Seat Cushion" in China's published patent case No. -74-74, due to the increased fine area of the airbag, reduces the acceptance force, but also increases the air-to-air due to the contact area of the airbag or high compression soft palate_ It can increase the lying temperature and seat, and can not eliminate the dissipation of heat and heat. It is more likely to cause ulcers. The scope of use is "seat cushion, seat, mattress, foot massage." In addition, the main purpose of this creation is that the convex grain high silk in its main structure cannot be replaced at any time. The main purpose of the cited case is to insert massage masses between the convex grains of the time. The main purpose is to provide "can be used as a breathable seat cushion, You can combine them to expand the area by yourself, and you can massage the bumps as a _massage test "; further analysis' It is mainly for" normal people "who can move limbs freely, and is not suitable for" patients with paralysis ". M282663 The above-mentioned various cushions can only reduce the contact pressure passively, but they cannot really relieve the problem of pressure ulcers in the patient's compressed area. At present, the only way to prevent pressure ulcers in patients who cannot sense and drive their limbs is to frequently move the patient by family members or caregivers, and continue to massage the patient to change the pressure site and promote blood circulation in the pressure site. However, on the one hand, it may not be able to take care of the patient's needs when massaging, and there are many injuries to the patient when exerting too much force; on the other hand, the so-called "prolonged illness without filial sons", people have passions and desires, and beans can be so intermittent The movement and massage movements are performed every ten minutes for several years or even decades; t It is that the activity of such patients is originally very small and the metabolism rate is quite low, that is, once pressure ulcers occur, the repair function from the body itself Relatively slower than normal people, as long as the caregiver is negligent or lazy, it is extremely difficult to completely recover the pressure ulcer occurrence site, so there is little "healing" at all. Infection caused by pressure ulcers, and even sepsis, threatens patients' lives. [New content] Therefore, the purpose of this creation is to provide a bulk pressure support device that conforms to the contour of the patient's body, to increase the area of money and reduce the pressure on all parts of the body. The other purpose of this creation is to provide a kind of long-term scattered pressure support device. Another purpose of this creation is to provide a diffuse pressure support device that automatically changes the pressure position to achieve the effect of automatic massage. Therefore, the scattered pressure branch building device of this creation is for supporting a specific user's lying body, including a base plate with a rough joint; compared with the number of joints, each branch building component includes -A body having-a top surface and-a connecting portion, and-a buffer member at least partially covering the top surface of the body, each body connecting portion is for connecting to the substrate mating portion, and each body top surface is connected to the connecting portion The length of the interval is equal to M282663 of the lying body wheel ^ money user. [Embodiment] The technical content, features and advantages of this new model will be clearly presented in conjunction with the following reference drawings and description of the preferred embodiment.
如第五及第六圖所示，本案第一較佳實施例包括一基板1，基 板上有複數接合部，在本例中是呈陣列排列的四百個穿孔10，以及 數目相對應的複數支撐元件2。其中，各穿孔10係分別由基板i頂 面向下凹所形成，而各穿孔10在遠離基板1頂面處，更分別形成 有一徑向收斂11。各支撐元件2分別包括一本體21與一緩衝件 22，本體21具有一頂面21卜及連接至基板丨對應穿孔1〇之一連結 部，在本例中，連結部即本體21插設於穿孔1〇中之部分，並藉由 徑向限縮11阻擋支撐元件本體21過度下降。秘合該歡使用者 之躺體輪廓，本案之每—支撲元件本體21細211至連結部間之長 度’需由使用者紐輪廓決定，例如坐骨附近部輯常受力較大、 位置較低，故支撐元件2之長度㈣較短，㈣部後緣受力較小、 位置較高，對應之支撐元件2長度較長，使得依本案技術製成之座 塾係如第人圖所不，具有完全量身打造之表面輪廓，充分分散使用 者接觸支撐物件部分之壓力，降健瘡發生機率。 為求通氣良好，在本例中各本體21更形成有上下貫穿之一通 孔210，其位置與基板丨上對應穿孔1G 向限縮11處内捏相配 合’使得各支狀件2本體21中央處亦可透氣。賴，此處之通氣 設計並非必要，即使本體21採和柱狀亦無不可，此時基板之穿孔 10可隨之改為盲孔。 :支料之所$ H件2本體21需為硬質材料，如木 質或瓣所形成，故键供緩衝及形變，在各本體21之頂面分別 至少部分騰22，魏謝物输可遞及舒 8 M282663 適材料。本例中，緩衝 延伸之環繞側面如，使得緩及由頂面細周緣向下 _易脫離。〜 I胁讀轉賴2〗上不致 於此技者所_理解，緩衝件頂面⑽與 ΓΓΓ整覆1Γ藉由麵而增加相對結合之麵，且緩衝件 狀為甜龍Γί 本體21之主要綠㈣即可，故可變更形 r而更胸h °且―旦_件長期受射彡變後’柯藉由單純剝 除而更換軸件，域將整纟歧雜置丢棄。 另方面，舰綱姻應個者輪_化 元件本嶋㈣肖_條㈣：m 丁在基板1之各穿孔10,中，分別埋設一具螺牙12,作為接合部， 而在各支擇元件2’之本體21，下方外緣，分別套設一具外螺紋之加， 作為連結部，使得支撐元件本體21’可械接合觸旋進退調節支 撐元件本體21，與緩衝件22’之高度。 除上述有效散壓之支樓裝置外’更進—步，亦可考量將所有支 樓元件循序降低，使得被降低部分之讀元件脫離使用者躯體表 面’讓該部分軀體所受壓力獲得釋放，微血管之血液重新流入，順 利供應氧氣與養份，並毅廢棄物，從而斧底輔達朗減壓瘡發 生機會之效果。 本案之第三較佳實施例如第九圖所示，將半數之支撐元件2，組 设於下基板12上、並將上基板π對應每一支撐元件2,位置形成一 穿孔130，而在交錯位置組裝另一半數目之支撐元件2,，，藉由升降 裝置帶動上基板13與下基板12彼此反向輪流沿箭頭方向所示升 降’使得支撐病患軀體之位置輪流釋放壓力，供血液回流。 當然，為使病患更難察覺身體下方之支撐變化，亦可如第十及 第十一圖所示，將散壓支撐裝置上之所有支撐元件按座標排列區分 M282663 在本例中，每一分區包括四 為複數分區 211、212、...221、222, 根支撐元件，並分別將m分區中之四根支樓元件依序標為2出、 2U2'2113、2114，212分區中之支樓元件則編號為助、助、 2123、2124。此時，如第九圖所示，配合四組升降裝置，以第一升 2111 ' 2⑵、···等，第二升降裝置驅動 第二組支航件㈣、迎、...，第三及第四升降裝置分別驅動第As shown in the fifth and sixth figures, the first preferred embodiment of the present case includes a substrate 1 having a plurality of joints, in this example four hundred perforations 10 arranged in an array, and a corresponding number of the plurality. Supporting element 2. Wherein, each of the perforations 10 is formed by the top surface of the substrate i being recessed, and each of the perforations 10 is formed with a radial convergence 11 away from the top surface of the substrate 1. Each support element 2 includes a main body 21 and a buffer member 22. The main body 21 has a top surface 21 and a connecting portion connected to the base plate corresponding to the perforation 10. In this example, the connecting portion, that is, the body 21 is inserted in A part of the perforation 10 is prevented from being excessively lowered by the radial restriction 11. The contour of the lying body of the user is closely related. The length between the thin 211 and the connecting part of the flutter element body in this case needs to be determined by the contour of the user. For example, the parts near the ischium are often stressed and the position is relatively large. Low, so the length ㈣ of the support element 2 is short, the rear edge of the crotch is less stressed, and the position is higher. The corresponding length of the support element 2 is longer, so that the seat made according to the technology of this case is not as shown in the figure. With a completely tailored surface profile, it fully disperses the pressure of the user in contact with the supporting object, reducing the incidence of ulcers. In order to achieve good ventilation, in this example, each body 21 is further formed with a through hole 210 penetrating up and down, and its position is matched with the corresponding perforation 1G on the substrate 11 to limit the shrinkage 11 places so that each branch 2 is centered on the body 21 Breathable everywhere. Lai, the ventilation design here is not necessary, even if the body 21 adopts a columnar shape, the perforation 10 of the substrate can be changed to a blind hole. : The material of the material $ H 2 The body 21 needs to be made of hard materials, such as wood or petals, so the keys are used for cushioning and deformation. At least part of the body 21 is at the top of each body 21, and Wei Xie ’s material can be delivered. Shu 8 M282663 suitable material. In this example, the surrounding side of the buffer extension is such that it eases off from the thin peripheral edge of the top surface down. ~ I threatened to read 2 and it would n’t be understood by this technician. The top surface of the cushion member ⑽ and ΓΓΓ cover 1Γ by the surface to increase the relative bonding surface, and the cushion member is the main part of the sweet dragon Γ. Green can be used, so you can change the shape r to more chest h ° and “Do n’t change the shaft parts by simply stripping after long-term shooting changes”, the domain will be discarded. On the other hand, the ship ’s marriage should be based on one's own abilities. The element 12 is embedded in each of the holes 10, 1 of the substrate 1, and a screw 12 is embedded as a joint portion, and each support is selected. The main body 21 of the element 2 'and the outer edge of the lower part are respectively provided with an external thread as a connection part, so that the supporting element body 21' can be mechanically engaged with the touch advance and retreat to adjust the height of the supporting element body 21 and the height of the buffer member 22 '. . In addition to the above-mentioned effective loose pressure branch device, 'going one step further, you can also consider sequentially lowering all branch components, so that the lowered reading element is off the surface of the user's body', so that the pressure on that part of the body is released The blood of the microvessels re-flows, smoothly supplies oxygen and nutrients, and wastes, which helps the effect of Dalang decompression ulcers. In the third preferred embodiment of the present case, as shown in the ninth figure, half of the supporting elements 2 are arranged on the lower substrate 12 and the upper substrate π corresponds to each supporting element 2 to form a perforation 130 at the position, and the staggered Position the other half of the number of supporting elements 2, and use the lifting device to drive the upper substrate 13 and the lower substrate 12 to rotate in opposite directions in the direction of the arrow, so that the positions supporting the patient's body are released in turn for blood to return. Of course, in order to make it more difficult for the patient to detect changes in the support under the body, as shown in Figures 10 and 11, all the support elements on the diffuse pressure support device can be arranged according to the coordinates to distinguish M282663. In this example, each The partition includes four supporting sections 211, 212, ... 221, 222, and four supporting components in the m section are sequentially labeled as 2 out, 2U2'2113, 2114, and 212 respectively. The components of the branch building are numbered Assist, Assist, 2123, 2124. At this time, as shown in the ninth figure, with the four sets of lifting devices, the second lifting device drives the second group of supporting parts ㈣, welcoming, ... with the first liter 2111 '2⑵, ..., etc., the third And the fourth lifting device respectively drive the first

The mosquito bracing element is reduced in age; in such a cycle and in turn, all pressured locations can obtain sufficient blood flow supply before substantial hypoxia and necrosis. With the self-guided operation of the human body, the fundamental factors that cause pressure ulcers can be removed without the need for massage. The third and second losers continued. The static tree and the wealth tree are two points mixed in the -static position that is close to the user '. When the control device starts to drive the lifting device, the above-mentioned' compose the health field device, and Lai Zashu design disperses the pressure 'in the first minute. The length from the top surface of each body to the connecting part is based on the body contour of the specific user. In other words, each piece of the healthy support device is "tailored", so that the force on each part of the body surface is evenly distributed. Effective dispersion of groundwork. After clinical experiments, Lang can effectively reduce the sitting green long relay force, and increase the contact area of the thighs, so that the correct posture of the seated and comfortable age of bedsores. The use of ^ through holes is good and it is easy to keep the fine surface not too thin, and it can be used for a long time and 7 punches can be found at a time.
