Description
本新型是有關於一種醫療照護用氣墊裝置,特別是指一種具有壓力感測功能的醫療照護用氣墊裝置及氣墊系統。The present invention relates to an air cushion device for medical care, in particular to an air cushion device and an air cushion system for medical care with a pressure sensing function.
一般長期臥床的患者若無法自主移動身體,容易因為肌肉長期接觸床面並受身體重量的壓力作用而產生壓瘡,所以照護者必須頻繁地協助患者翻動身體以避免產生壓瘡。In general, patients who are bedridden for a long time cannot move their bodies voluntarily, and pressure ulcers are prone to be caused by the muscles touching the bed surface for a long time and the pressure of the body weight. Therefore, caregivers must frequently assist patients to turn the body to avoid pressure ulcers.
為了減輕照護者的負擔,現有一種氣墊床,利用可交替充氣及洩氣的氣囊以輪流釋放患者身體各部位肌肉的壓力。其原理是將多個管狀氣囊沿一直線並排以組成床墊大小,以相鄰的氣囊兩個一組或三個一組,同一組的氣囊輪流洩氣及充氣,以兩個一組為例說明,當其中一氣囊充氣時另一氣囊則洩氣,如此由每組充氣的氣囊支撐患者身體,而每組洩氣的氣囊不與患者身體接觸,藉此使患者的肌肉釋放壓力,一段時間再使洩氣的氣囊充氣並使充氣的氣囊洩氣,如此交替充氣和洩氣而能使患者的身體肌肉輪流釋放壓力,以降低產生壓瘡的風險。In order to reduce the burden on caregivers, there is an existing air bed that utilizes airbags that can be alternately inflated and deflated to release the pressure of muscles in various parts of the patient's body in turn. The principle is to arrange multiple tubular airbags side by side to form a mattress size. Two or three sets of adjacent airbags are used, and the airbags of the same group take turns to deflate and inflate. Take two groups as an example. When one of the airbags is inflated, the other airbag is deflated, so that each group of inflated airbags supports the patient's body, and each group of deflated airbags does not contact the patient's body, thereby releasing the pressure of the patient's muscles, and then deflated The airbag inflates and deflates the inflated airbag, so alternately inflating and deflating can enable the patient's body muscles to release pressure in turn, so as to reduce the risk of pressure ulcers.
然而,由於各式各樣患者的身形與體重均不相同,現有的氣墊床無法確保患者使用時氣囊的壓力是否足以支撐患者,當氣囊壓力過低時,患者身體會壓在全部的氣囊上,即使部分氣囊洩氣也無法達到釋放肌肉壓力的效果。如何即時監控患者與氣囊的接觸狀況以避免讓肌肉釋放壓力的效果失效,是有待解決的問題。However, due to the different body shapes and weights of various patients, existing air mattresses cannot ensure that the pressure of the airbag is sufficient to support the patient during use. When the pressure of the airbag is too low, the patient's body will be pressed on all the airbags. , Even if some of the airbags are flat, the effect of releasing muscle pressure cannot be achieved. How to monitor the patient's contact with the airbag in real time to avoid the effect of releasing the pressure of the muscles is not a problem to be solved.
因此,本新型之其中一目的,即在提供一種可以解決前述問題的醫療照護用氣墊裝置及氣墊系統。Therefore, one object of the present invention is to provide an air cushion device and an air cushion system for medical care that can solve the foregoing problems.

在本實施例中,該感測單元51還具有一柔性基板511,例如以熱塑性聚氨酯(TPU)、聚氨酯(PU)等高分子材料製的薄膜,且該導電線路圖案512以印刷方式形成於該柔性基板511表面,該導電線路圖案512的導線512a、512b各具有靠近該轉接單元52的一連接端部512d且其中一條導線為共用導線512a,其餘導線為獨立導線512b,若共用導線512a設為正極則獨立導線512b為負極,反之,若共用導線512a設為負極則獨立導線512b為正極,亦即,共用導線512a與獨立導線512b為不同極性。該等獨立導線512b各自還具有位於末端的一第一電極部512e,該共用導線512a具有分別配合該等第一電極部512e的多個第二電極部512f以使每一第二電極部512f與對應的第一電極部512e共同形成其中一感測點512c。可理解地,在變化的實施例,多個第二電極部512f亦可形成於不同導線上。該等導線512a、512b整體由導電銀漿印刷而成且該等第一電極部512e和該等第二電極部512f還於導電銀漿表面印刷覆蓋一層導電係數小於導電銀漿的導電油墨,例如碳系導電油墨,以降低第一電極部512e和第二電極部512f的導電靈敏度。每一導電塊513具有一基層513a,及被覆於該基層513a的一導電層513b,在本實施例中,該導電層513b包括一層被覆於該基層513a的高導電係數材料5131,及一層位於表層且被覆於該高導電係數材料5131的低導電係數材料5132,該低導電係數材料5132的導電係數低於該高導電係數材料5131。基層513a可例如以聚對苯二甲酸乙二酯(PET)、熱塑性聚氨酯(TPU)、聚氨酯(PU)等高分子材料製的薄膜,該高導電係數材料5131為銀漿,該低導電係數材料5132為導電油墨且以碳系導電油墨較佳。導電塊513可藉由基層513a與柔性基板511以熱壓接合或膠黏固定。導電層513b以印刷方式形成於基層513a上,且低導電係數材料5132的阻抗可依使用需求調整。該低導電係數材料5132除了用以保護銀漿以避免銀漿被氧化,且用以避免高導電係數材料5131直接接觸第一電極部512e和第二電極部512f而使感測點512c一直處於導通狀態無法具有感測功能。換言之,由於低導電係數材料5132的導電係數較低,在感測點512c未受壓時阻抗較大而使第一電極部512e和第二電極部512f處於未導通狀態,當感測點512c受壓時,高導電係數材料5131會參與導電而使阻抗降低,感測點512c的壓力越大會使較多的高導電係數材料5131參與導電而降低阻抗。同樣地,藉由低導電係數材料5132位於表層與第一電極部512e和第二電極部512f接觸以降低導電靈敏度,如此能增加感測電路的作用區間以增加可供分析的資訊。In this embodiment, the sensing unit 51 further has a flexible substrate 511, for example, a film made of a polymer material such as thermoplastic polyurethane (TPU), polyurethane (PU), and the like, and the conductive circuit pattern 512 is formed on the printed circuit. On the surface of the flexible substrate 511, the wires 512a, 512b of the conductive circuit pattern 512 each have a connection end 512d near the adapter unit 52, and one of the wires is a common wire 512a, and the remaining wires are independent wires 512b. For the positive electrode, the independent lead 512b is the negative electrode. On the other hand, if the common lead 512a is set to the negative electrode, the independent lead 512b is the positive electrode, that is, the common lead 512a and the independent lead 512b have different polarities. Each of the independent wires 512b also has a first electrode portion 512e at the end, and the common wire 512a has a plurality of second electrode portions 512f respectively matching the first electrode portions 512e so that each of the second electrode portions 512f and The corresponding first electrode portions 512e collectively form one of the sensing points 512c. Understandably, in a different embodiment, a plurality of second electrode portions 512f may also be formed on different wires. The wires 512a and 512b are printed by conductive silver paste as a whole, and the first electrode portions 512e and the second electrode portions 512f are also printed on the surface of the conductive silver paste and covered with a conductive ink having a conductivity lower than that of the conductive silver paste, such as The carbon-based conductive ink reduces the conductivity sensitivity of the first electrode portion 512e and the second electrode portion 512f. Each conductive block 513 has a base layer 513a and a conductive layer 513b covering the base layer 513a. In this embodiment, the conductive layer 513b includes a high-conductivity coefficient material 5131 covered on the base layer 513a, and a layer on the surface layer. The low-conductivity material 5132 covered with the high-conductivity material 5131 has a lower conductivity than the high-conductivity material 5131. The base layer 513a can be, for example, a film made of a polymer material such as polyethylene terephthalate (PET), thermoplastic polyurethane (TPU), polyurethane (PU), etc. The high-conductivity coefficient material 5131 is a silver paste, and the low-conductivity material 5132 is a conductive ink and a carbon-based conductive ink is preferred. The conductive block 513 can be bonded to the flexible substrate 511 by thermocompression or adhesively fixed through the base layer 513a. The conductive layer 513b is formed on the base layer 513a by printing, and the impedance of the low-conductivity coefficient material 5132 can be adjusted according to use requirements. In addition to protecting the silver paste from being oxidized, the low-conductivity material 5132 is also used to prevent the high-conductivity material 5131 from directly contacting the first electrode portion 512e and the second electrode portion 512f so that the sensing point 512c is always on. Status cannot be sensed. In other words, due to the low conductivity of the low-conductivity coefficient material 5132, the impedance is large when the sensing point 512c is not stressed, so that the first electrode portion 512e and the second electrode portion 512f are in a non-conducting state. When pressure is applied, the high-conductivity-coefficient material 5131 will participate in conduction to reduce the impedance. The greater the pressure at the sensing point 512c, the more high-conductivity-coefficient material 5131 will participate in conduction to reduce the impedance. Similarly, the low-conductivity coefficient material 5132 is located on the surface to be in contact with the first electrode portion 512e and the second electrode portion 512f to reduce the conductivity sensitivity. This can increase the action range of the sensing circuit and increase the information available for analysis.
在變化的實施例,參閱圖5與圖6,導電塊513的導電層513b也可以是單一材料所形成,例如以導電油墨印刷於基層513a所形成,且每一導電塊513的導電層513b與對應感測點512c之間還可設有一絕緣層513c,且該絕緣層513c具有多個鏤空區5131,該等鏤空區5131分布的位置與該感測點512c的正、負極導線512a、512b(即第一電極部512e和第二電極部512f)相對應,以藉由該等鏤空區5131調整該導電層513b與對應的正、負極導線512a、512b的接觸面積。也就是說,鏤空區5131的形狀、大小及數量可以變化調整,例如圖7所示為另一種鏤空區5131的佈設態樣。藉由調整絕緣層513c的厚度和鏤空區5131的形狀、大小及數量,可以調整患者施壓於導電塊513時導電層513b與正、負極導線512a、512b (即第一電極部512e和第二電極部512f)接觸的面積,而藉由減少導電層513b與正、負極導線512a、512b的接觸面積可以降低導電靈敏度,進而增加感測電路的作用區間以增加可供分析的資訊。該絕緣層513c可以是導電塊513的一部份,例如以印刷方式形成於該導電層513b表面,在製造上較為方便,但是該絕緣層513c也可以和導電塊513分開製作,先在導電線路圖案512表面設置絕緣層513c後再設置導電塊513。在其他的變化態樣,導電塊513亦可由導電橡膠製成,或是為含有導電紗製成的織物,導電橡膠及含有導電紗製成的織物皆可因受壓而增加導電性(降低阻抗)。In a modified embodiment, referring to FIG. 5 and FIG. 6, the conductive layer 513 b of the conductive block 513 may also be formed of a single material, for example, formed by printing conductive ink on the base layer 513 a, and the conductive layer 513 b of each conductive block 513 and An insulating layer 513c may also be provided between the corresponding sensing points 512c, and the insulating layer 513c has a plurality of hollow areas 5131, and the positions of the hollow areas 5131 and the positive and negative lead wires 512a, 512b of the sensing points 512c ( That is, the first electrode portion 512e corresponds to the second electrode portion 512f), so that the contact areas of the conductive layer 513b and the corresponding positive and negative lead wires 512a, 512b are adjusted by the hollow regions 5131. That is, the shape, size, and number of the hollowed-out areas 5131 can be changed and adjusted. For example, FIG. 7 shows another layout of the hollowed-out areas 5131. By adjusting the thickness of the insulating layer 513c and the shape, size, and number of the hollow areas 5131, the conductive layer 513b and the positive and negative lead wires 512a and 512b (that is, the first electrode portion 512e and the second The contact area of the electrode portion 512f), and by reducing the contact area of the conductive layer 513b and the positive and negative lead wires 512a, 512b, the conductive sensitivity can be reduced, and the action interval of the sensing circuit can be increased to increase the information that can be analyzed. The insulating layer 513c may be a part of the conductive block 513. For example, the insulating layer 513c is formed on the surface of the conductive layer 513b by printing, which is convenient in manufacturing. However, the insulating layer 513c can also be manufactured separately from the conductive block 513. A conductive block 513 is provided after an insulating layer 513c is provided on the surface of the pattern 512. In other variations, the conductive block 513 can also be made of conductive rubber, or a fabric made of conductive yarn, and both conductive rubber and fabric made of conductive yarn can increase conductivity due to compression (reduce impedance ).

The side facing the main airbag 11 is not limited. In a modified embodiment, the conductive circuit pattern 512 can also be printed directly on the surface of the main airbag 11.
該轉接單元52電連接該感測單元51與該匯流傳輸模組4以將該感測單元51測得的感測訊號傳輸至該匯流傳輸模組4。在本實施例中,該轉接單元52為柔性電路板,具有一第一轉接電路521、一第二轉接電路522及一微處理器523。該第一轉接電路521與該感測單元51電連接,該第二轉接電路522與該匯流傳輸模組4電連接,該微處理器523電連接該第一轉接電路521與該第二轉接電路522且彙整自該第一轉接電路521接收的感測訊號再傳輸至該第二轉接電路522,而使該第二轉接電路522的導線512a、512b數量少於該第一轉接電路521。具體而言,在本實施例中,第一轉接電路521共有七條線路以配合導電線路圖案512的導線512a、512b數量,導電線路圖案512以七條導線512a、512b形成六個感測點512c,導電線路圖案512的導線512a、512b數量可以視所需感測點512c的數量增加或減少,第一轉接電路521的線路數量即配合導電線路圖案512的導線512a、512b數量調整。該微處理器523對應每個感測點512c設定一身份識別(ID)以供辨識感測訊號是源自哪個位置的感測點512c,並將訊號彙整通過第二轉接電路522的其中兩條線路傳輸訊號至匯流傳輸模組4。在本實施例中,第二轉接電路522共有四條線路,其中兩條傳輸訊號,而另兩條傳輸電源,但是在變化的實施例,第二轉接電路522也可以只有兩條線路,使電源和訊號共用線路傳輸。換言之,第一轉接電路521的線路數量需配合導電線路圖案512的導線512a、512b數量調整,而通過微處理器523處理接收自感測單元51的訊號後再傳輸至第二轉接電路522,即可使第二轉接電路522只需要兩條線路傳輸微處理器523處理過的訊號,亦即,當導電線路圖案512的導線512a、512b數量增加以增加感測點512c數量時,第二轉接電路522仍然只要兩條線路或四條線路即可,藉此匯流傳輸模組4的傳輸電路41配合第二轉接電路522僅需要兩條線路或四條線路即可,而能減少匯流傳輸模組4的傳輸電路41的線路數量且不需要對應導電線路圖案512的導線512a、512b數量調整。在本實施例,匯流傳輸模組4的傳輸電路41配合第二轉接電路522具有四條線路以供第二轉接電路522的線路與傳輸電路41的線路一對一電連接。The switching unit 52 is electrically connected to the sensing unit 51 and the bus transmission module 4 to transmit the sensing signals measured by the sensing unit 51 to the bus transmission module 4. In this embodiment, the switching unit 52 is a flexible circuit board, and has a first switching circuit 521, a second switching circuit 522, and a microprocessor 523. The first transfer circuit 521 is electrically connected to the sensing unit 51, the second transfer circuit 522 is electrically connected to the bus transmission module 4, and the microprocessor 523 is electrically connected to the first transfer circuit 521 and the first transfer circuit 521. The two switching circuits 522 and the sensing signals received from the first switching circuit 521 are transmitted to the second switching circuit 522, so that the number of wires 512a, 512b of the second switching circuit 522 is less than that of the first switching circuit 522. A switching circuit 521. Specifically, in this embodiment, the first transfer circuit 521 has a total of seven lines to match the number of the conductive lines 512a and 512b of the conductive line pattern 512, and the conductive line pattern 512 forms six sensing points 512c with the seven conductive lines 512a and 512b. The number of wires 512a, 512b of the conductive circuit pattern 512 can be increased or decreased according to the number of required sensing points 512c. The number of lines of the first transfer circuit 521 is adjusted in accordance with the number of wires 512a, 512b of the conductive circuit pattern 512. The microprocessor 523 sets an identification (ID) corresponding to each sensing point 512c to identify the sensing point 512c from which the sensing signal originates, and integrates the signal through two of the second switching circuits 522. Transmission lines to the bus transmission module 4. In this embodiment, the second switching circuit 522 has a total of four lines, two of which transmit signals and the other two transmit power, but in a variant embodiment, the second switching circuit 522 may also have only two lines, so that Power and signal are transmitted on the same line. In other words, the number of lines of the first transfer circuit 521 needs to be adjusted in accordance with the number of wires 512a, 512b of the conductive line pattern 512, and the signal received from the sensing unit 51 is processed by the microprocessor 523 and then transmitted to the second transfer circuit 522. That is, the second switching circuit 522 only needs two lines to transmit the signals processed by the microprocessor 523, that is, when the number of the wires 512a, 512b of the conductive circuit pattern 512 is increased to increase the number of the sensing points 512c, the first The two switching circuits 522 still only need two lines or four lines, so that the transmission circuit 41 of the bus transmission module 4 and the second switching circuit 522 only need two lines or four lines, which can reduce the bus transmission. The number of lines of the transmission circuit 41 of the module 4 does not need to be adjusted for the number of wires 512 a and 512 b corresponding to the conductive line pattern 512. In this embodiment, the transmission circuit 41 of the bus transmission module 4 cooperates with the second transfer circuit 522 to have four lines for the one-to-one electrical connection between the line of the second transfer circuit 522 and the line of the transmission circuit 41.

再者,本新型醫療照護用氣墊系統控制氣墊模組1充氣及洩氣的方法的一實施例如圖11所示。首先,如圖11的步驟S11所示,該主機3一開始運作時,該主機3中的該控制模組31會根據偵測該供氣模組31的該充氣氣壓的該氣體壓力感測器回傳的該氣體壓力感測訊號及該等感測模組5的該等感測點512c回傳的該接觸壓力感測訊號,得知該等主氣囊11內部的一氣體壓力(亦即該充氣氣壓相當於該等主氣囊11內部的氣體壓力)以及該等主氣囊11外部由使用者造成的一接觸壓力,並如圖11的步驟S12所示,根據該充氣氣壓及該等接觸壓力產生一控制訊號控制該供氣模組32透過該第一輸氣管路13和該第二輸氣管路14對該等主氣囊11充氣。具體而言,該控制模組31會根據該充氣氣壓與預設的一第一目標值的差距以及該等接觸壓力中的一最大值與一第二目標值的差距產生該控制訊號,使控制該供氣模組32調整輸出至該第一輸氣管路13和該第二輸氣管路14的該充氣氣壓,並持續對該等主氣囊11充氣。Furthermore, an embodiment of a method for controlling the inflation and deflation of the air cushion module 1 of the novel air cushion system for medical care is shown in FIG. 11. First, as shown in step S11 in FIG. 11, when the host 3 starts to operate, the control module 31 in the host 3 will detect the gas pressure sensor of the gas pressure of the gas supply module 31 according to the gas pressure sensor. The gas pressure sensing signal returned and the contact pressure sensing signal returned by the sensing points 512c of the sensing modules 5 know that a gas pressure (i.e. the The inflation pressure is equivalent to the gas pressure inside the main airbags 11) and a contact pressure caused by the user outside the main airbags 11, and as shown in step S12 of FIG. 11, the air pressure is generated according to the inflation air pressure and the contact pressures. A control signal controls the gas supply module 32 to inflate the main airbags 11 through the first gas pipeline 13 and the second gas pipeline 14. Specifically, the control module 31 generates the control signal according to the difference between the inflation pressure and a preset first target value and the difference between a maximum value of the contact pressures and a second target value, so that the control signal The air supply module 32 adjusts the inflation pressure output to the first gas transmission line 13 and the second gas transmission line 14, and continuously inflates the main airbags 11.
然後,如圖11的步驟S13所示,該控制模組31判斷該充氣氣壓是否達到該第一目標值,以及該等主氣囊11的該接觸壓力的該最大值是否已達到該第二目標值,若否,則再次回到步驟S11,繼續控制該供氣模組32對該等主氣囊11充氣;若是,則如圖11的步驟S14所示,該控制模組32判斷該氣墊模組1是否被設定運作在交替模式,若否,則回到步驟S11,持續控制該供氣模組32對該等主氣囊11充氣,使該等主氣囊11的氣壓維持在該目標值;若是,則如圖11的步驟S15,該控制模組31控制該供氣模組32透過該第一輸氣管路13和該第二輸氣管路14對該等主氣囊11交替供氣及洩氣,例如由該第一輸氣管路13對位於單數位置的主氣囊11進行充氣,並由該第二輸氣管路14對位於偶數位置的主氣囊11進行洩氣;然後,如圖11的步驟S16,該控制模組31持續根據該氣體壓力感測器回傳的該氣體壓力感測訊號以及該等感測模組5回傳的該接觸壓力感測訊號,得知該等被充氣的主氣囊11內部的該氣體壓力以及外部的該接觸壓力。Then, as shown in step S13 of FIG. 11, the control module 31 determines whether the inflation pressure reaches the first target value, and whether the maximum value of the contact pressure of the main airbags 11 has reached the second target value. If not, return to step S11 again and continue to control the air supply module 32 to inflate the main airbags 11; if so, as shown in step S14 of FIG. 11, the control module 32 determines the air cushion module 1 Whether it is set to operate in the alternate mode; if not, it returns to step S11 to continuously control the air supply module 32 to inflate the main airbags 11 so that the air pressure of the main airbags 11 is maintained at the target value; if so, then As shown in step S15 in FIG. 11, the control module 31 controls the gas supply module 32 to alternately supply and deflate the main airbags 11 through the first gas pipeline 13 and the second gas pipeline 14, for example, by the The first gas pipeline 13 inflates the main airbag 11 located in the singular position, and the second gas pipeline 14 deflates the main airbag 11 located in the even position; then, as shown in step S16 of FIG. 11, the control module 31 Continuously returns the gas pressure according to the gas pressure sensor Such sense signal sensing module 5 and return the contact pressure sense signal, and that the gas pressure inside the external those primary airbag 11 is inflated the contact pressure.
接著如圖11的步驟S17,該控制模組31會根據上述的該充氣氣壓及該等接觸壓力產生一控制訊號控制該供氣模組32調整該充氣氣壓。具體而言,該控制模組31會根據該充氣氣壓與該第一目標值的差距產生該控制訊號,控制該供氣模組32適當調整該充氣氣壓,以使該充氣氣壓在交替模式下能維持在該第一目標值。Next, as shown in step S17 in FIG. 11, the control module 31 generates a control signal to control the air supply module 32 to adjust the inflation pressure according to the aforesaid inflation pressure and the contact pressure. Specifically, the control module 31 generates the control signal according to the difference between the inflation pressure and the first target value, and controls the gas supply module 32 to appropriately adjust the inflation pressure so that the inflation pressure can be changed in the alternate mode. Maintained at this first target value.
然後,如圖1的步驟S18,該控制模組31再次判斷被供氣的該等主氣囊11是否已完成供氣(即該充氣氣壓已達到該第一目標值且該接觸壓力的最大值已達到該第二目標值),若否,則回到步驟S16,持續偵測該充氣氣壓以及該等主氣囊外部的該接觸壓力,並重覆步驟S17;若是,則如圖11的步驟S19,該控制模組31判斷是否收到一關機訊號,若是,該控制模組31將停止運作,若否,如圖1的步驟S20,該控制模組31判斷是否達到預設的一交替時間,例如15分鐘,若否,則回到步驟S16,持續偵測該充氣氣壓及該等主氣囊11外部的該接觸壓力,並重覆步驟S17,若是,則進行圖11的步驟S21,產生一交替控制訊號並傳送該交替控制訊號給該供氣模組32,並回到步驟S15,使該供氣模組32改成例如由該第一輸氣管路13對位於單數位置的主氣囊11洩氣,並由該第二輸氣管路14對位於偶數位置的主氣囊11充氣。藉此,使該等主氣囊11中的氣壓在交替充氣及洩氣的過程中能維持在目標數值。並且該控制模組31還記錄交替事件,例如記錄交替的時間點以及交替當下該等主氣囊11內部的該氣體壓力以及外部的該接觸壓力等,以供後續分析該交替模式對於改善使用者臥床問題等之應用。Then, as shown in step S18 in FIG. 1, the control module 31 judges whether the supplied main airbags 11 have been supplied with air again (that is, the inflation pressure has reached the first target value and the maximum value of the contact pressure has been reached). Reach the second target value), if not, go back to step S16, continue to detect the inflation pressure and the contact pressure outside the main airbags, and repeat step S17; if yes, then as shown in step S19 of FIG. 11, the The control module 31 determines whether a shutdown signal is received. If so, the control module 31 will stop operating. If not, as shown in step S20 of FIG. 1, the control module 31 determines whether a preset alternate time is reached, such as 15 Minutes, if not, go back to step S16, continue to detect the inflation pressure and the contact pressure outside the main airbag 11, and repeat step S17, if yes, go to step S21 of FIG. 11 to generate an alternate control signal and Send the alternating control signal to the gas supply module 32, and return to step S15 to change the gas supply module 32 to, for example, deflate the main airbag 11 located in the singular position by the first gas transmission line 13 and be deflated by the 14 pairs of second gas pipelines are even-numbered The main airbag 11 inflated. Thereby, the air pressure in the main airbags 11 can be maintained at a target value during the process of alternately inflating and deflating. And the control module 31 also records alternation events, such as the time point of the alternation and the current gas pressure inside the main airbags 11 and the external contact pressure, etc., for subsequent analysis. The alternation mode is useful for improving the user's bed. Application of questions, etc.
再者,在該主機3運作的過程中,該控制模組31還可藉由分析每個感測模組5的該感測點512c回傳的接觸壓力感測訊號所代表的該接觸壓力,判斷使用者(患者)臥床與否以及臥床的姿態並予以記錄。首先,如圖12的步驟S21所示,該控制模組31會持續地接收來自每個感測點512c回傳的該接觸壓力感測訊號,而從該等接觸壓力感測訊號得知該等被充氣的主氣囊11外部的該接觸壓力以及該等被洩氣的主氣囊11外部的該接觸壓力。然後,如圖12的步驟S22所示,該控制模組31會定時地,例如但不限於每隔1分鐘,根據該等主氣囊11的該等接觸壓力的數值大小,判斷使用者是否臥床,若是,亦即有部分的主氣囊11的該等接觸壓力的數值明顯高於其餘部分的主氣囊11的該等接觸壓力,例如兩者壓力值之差異高於一第一預設值,該控制模組31即判定使用者有臥床。In addition, during the operation of the host 3, the control module 31 can also analyze the contact pressure represented by the contact pressure sensing signal returned by the sensing point 512c of each sensing module 5, Determine whether the user (patient) is bedridden or not and record the bedridden posture. First, as shown in step S21 in FIG. 12, the control module 31 continuously receives the contact pressure sensing signal returned from each sensing point 512c, and learns the contact pressure sensing signals from the contact pressure sensing signals. The contact pressure outside the inflated main airbag 11 and the contact pressure outside the deflated main airbag 11. Then, as shown in step S22 of FIG. 12, the control module 31 will determine whether the user is lying in bed according to the magnitude of the contact pressure of the main airbag 11, such as, but not limited to, every 1 minute. If yes, that is, the values of the contact pressures of some of the main airbags 11 are significantly higher than those of the other main airbags 11, for example, the difference between the pressure values of the two is higher than a first preset value, the control The module 31 determines that the user has a bed.
然後,如圖12的步驟S23所示,該控制模組31進一步分析該等感測點512c回傳的該接觸壓力感測訊號所對應的該等接觸壓力的數值變化及其分佈範圍,以判斷使用者的臥床姿態是正躺(仰躺)、右側臥、左側臥或坐起等。例如當接觸壓力較高的區域主要分佈在由該等主氣囊11組成的氣墊床的中間位置時,則該控制模組31判斷使用者處於正躺(仰躺)姿態;當接觸壓力較高的區域主要分佈在氣墊床的靠右邊位置時,則該控制模組31判斷使用者處於右側臥姿態;當接觸壓力較高的區域主要分佈在氣墊床的靠左邊位置時,該控制模組31判斷使用者處於左側臥姿態。然後,如圖12的步驟S24所示,該控制模組31記錄判斷的結果,其中包含但不限於臥床姿態及判斷當下的時間等。Then, as shown in step S23 in FIG. 12, the control module 31 further analyzes the numerical changes of the contact pressures and the distribution ranges of the contact pressures corresponding to the contact pressure sensing signals returned by the sensing points 512 c to determine The bed posture of the user is lying on his back (lying on his back), lying on his right side, lying on his left side, or sitting up. For example, when the area with high contact pressure is mainly distributed in the middle position of the air cushion bed composed of the main airbags 11, the control module 31 determines that the user is in a lying (lying) posture; when the contact pressure is high, When the area is mainly distributed on the right side of the air bed, the control module 31 judges that the user is in the right lying posture; when the area with high contact pressure is mainly located on the left side of the air bed, the control module 31 determines The user is in a left lying position. Then, as shown in step S24 of FIG. 12, the control module 31 records the result of the judgment, including but not limited to the posture of lying in bed and judging the current time.
藉此,該控制模組31可以監測使用者維持同一臥床姿態的一持續時間,並判斷該持續時間達到一預設值,例如二小時時,即判定會有壓瘡的風險,因此該控制模組31會針對壓瘡風險適時地透過該輸出單元輸出一壓瘡風險預警通知。In this way, the control module 31 can monitor a duration for which the user maintains the same bed posture, and judge that the duration reaches a preset value, for example, when two hours, it is determined that there is a risk of pressure ulcers. Therefore, the control module 31 The group 31 will output a pressure ulcer risk warning notification through the output unit in time for the pressure ulcer risk.
此外,該控制模組31藉由分析該等感測點512c回傳的該接觸壓力感測訊號所對應的該等接觸壓力的數值變化及分佈範圍,判斷使用者為坐起姿勢時,控制該供氣模組32增加該充氣氣壓,亦即增加被充氣的該等主氣囊11的內部氣壓,以讓使用者坐起來更為舒適,同時該控制模組31會透過該輸出單元輸出一坐起通知。In addition, the control module 31 analyzes the change and distribution range of the contact pressure corresponding to the contact pressure sensing signal returned by the sensing points 512c, and controls the user when the user is in a sitting posture. The air supply module 32 increases the inflation pressure, that is, increases the internal pressure of the inflated main airbags 11 to make the user sit more comfortable. At the same time, the control module 31 outputs a sit-up through the output unit. Notice.
而在步驟S22中,若該控制模組31根據每個感測點512c回傳的該接觸壓力感測訊號所對應的該接觸壓力,判斷使用者並未臥床(即離床),比如全部的感測點512c回傳的該接觸壓力感測訊號所對應的該接觸壓力的數值差異不大且皆小於一第二預設值,則該控制模組31判斷使用者離床,並執行步驟S24,記錄判斷的結果,例如記錄判斷當下的時間(即離床時間)。同時,該控制模組31也會透過該輸出單元輸出一離床通知。In step S22, if the control module 31 determines that the user is not bedridden (that is, leaves the bed) according to the contact pressure corresponding to the contact pressure sensing signal transmitted back from each sensing point 512c, for example, all the sensors The value of the contact pressure corresponding to the contact pressure sensing signal returned by the measurement point 512c is not large and is less than a second preset value, the control module 31 determines that the user is out of bed, and executes step S24 to record The result of the judgment, such as recording the current time of judgment (that is, the time of leaving the bed). At the same time, the control module 31 also outputs a notification of leaving the bed through the output unit.
或者,該控制模組31在判斷使用者為坐起姿態後,還會持續地根據該等接觸壓力的數值變化及分佈範圍,判斷該等接觸壓力重心位置往床邊移動且接近一臨界值時,判定使用者可能想要離床,則該控制模組31會透過該輸出單元輸出一離床預警通知。並且,該控制模組31發出該離床預警通知後,仍會持續地根據該等接觸壓力的數值變化及分佈範圍,判斷該等接觸壓力的數值變化均小於一臨界數值時,判定使用者已經離床,則該控制模組31會透過該輸出單元輸出一已經離床通知。Alternatively, after determining that the user is in a sitting posture, the control module 31 will continue to judge when the position of the center of gravity of the contact pressure moves toward the bedside and approaches a critical value based on the numerical change and distribution range of the contact pressure. If it is determined that the user may want to leave the bed, the control module 31 outputs a warning of leaving the bed through the output unit. In addition, after the control module 31 sends out the bed warning notice, it will continue to judge that the value of the contact pressure is less than a critical value according to the change and distribution range of the contact pressure, and determine that the user has left the bed. Then, the control module 31 outputs a notification of having left the bed through the output unit.
然後,如圖11的步驟S25,該控制模組31判斷是否收到一關機訊號,若是,則令氣墊裝置停止運作,若否,則再次回到步驟S21。Then, as shown in step S25 in FIG. 11, the control module 31 determines whether a shutdown signal is received, and if so, stops the air cushion device, and if not, returns to step S21 again.
此外,在該交替模式下,當該控制模組31發現該等主氣囊11中的氣壓在交替充氣及洩氣的過程無法達到目標數值,例如該控制模組31會持續地根據該等接觸壓力感測訊號,判斷該等被充氣的主氣囊11的該接觸壓力的數值在一預設時間(例如5分鐘)內,未能達到一最低預設值,且該等被洩氣的主氣囊11的該接觸壓力的數值在該預設時間內亦未能低於一最高預設值時,該控制模組31判定充氣及洩氣異常並透過該輸出單元輸出一觸底(bottom out)預警通知。In addition, in the alternating mode, when the control module 31 finds that the air pressure in the main airbags 11 cannot reach the target value during the process of alternate inflation and deflation, for example, the control module 31 will continuously A test signal to determine that the value of the contact pressure of the inflated main airbags 11 fails to reach a minimum preset value within a preset time (for example, 5 minutes), and that the When the value of the contact pressure does not fall below a highest preset value within the preset time, the control module 31 determines that the inflation and deflation are abnormal and outputs a bottom out warning notification through the output unit.
而且,上述的該輸出單元除了將該壓瘡風險預警通知、該離床預警通知、該已經離床通知及該觸底預警通知輸出至該顯示器顯示並令該揚聲器發出相對應的警示音之外,該輸出單元還會透過其中的該無線傳輸模組33發送(傳送)至照護者的該行動裝置或一監視器,讓照護者能透過該行動裝置或該監視器發送控制訊號或設定資訊給該控制模組31,以遠端監控該氣墊模組1;或者該無線傳輸模組33也可將上述該等通知發送至一雲端伺服器(圖未示),且照護者可透過能與該雲端伺服器連接的該行動裝置或該監視器從該雲端伺服器接收上述該等通知訊息,並透過該雲端伺服器發送控制訊號或設定資訊給該控制模組31,以遠端監控氣墊模組1。In addition, the output unit described above, in addition to outputting the pressure ulcer risk warning notification, the bed departure warning notification, the bed departure notification, and the bottom warning notification, is output to the display and causes the speaker to emit a corresponding warning sound.
