下面的描述应用于本发明的所有方面。 The following description applies to all aspects of the invention.

在本发明的第一和第二方面,在抽吸的物质进入泵之前,分离机构将从伤口抽吸的流体与气体分离。 In the first and second aspects of the present invention, before the material enters the pump suction, the suction separating means from the wound fluid and gas separation. 因此,可以至少基本上防止从伤口抽吸的流体和可能还有固体物质进入泵中,由此可以避免对于泵的磨损和泵阻塞的危险。 Thus, the wound may be at least substantially prevented from pumping fluid and possibly, thereby to avoid the risk of clogging in the solid matter enters the pump to the pump and the pump wear. 而且,不抽吸液体和固体物质的泵可以更简单, 由于在泵中粘性阻力较少而需要较小的驱动力,而且以比那些抽吸液体和/或固体物质的泵低的成本制造。 Further, the pump is not pumping liquid and solid matter can be simpler due to less viscous resistance in the pump and requires less drive force, and lower than those at the suction pump liquid and / or solid matter of the cost of manufacturing. 泵可以包括蠕动泵,在该蠕动泵中,负压通过管的流动横截面的连续收缩和膨胀来产生,收缩和膨胀例如由可转动元件实现,该可转动元件具有作用在管的外表面上的一个或多个突出部分,由此引起管的流动横截面接连收缩和膨胀。 The pump may comprise a peristaltic pump, the peristaltic pump, the negative pressure cross-section through the contraction and expansion of a continuous flow tube to produce, for example, realized by the expansion and contraction of the rotatable member, the rotatable member has an effect on the outer surface of the tube one or more protruding portions, thereby causing the flow tube cross section successive contraction and expansion. 可替换地,泵可以包括至少一个可往复运动元件,比如活塞或隔膜,所述元件被布置成使抽吸腔连续收缩和膨胀,在该抽吸腔的进口和出口处优选地设有相应的单向阀。 Alternatively, the pump may comprise at least one reciprocable member, such as piston or diaphragm, said element is arranged so that contraction and expansion of a continuous suction chamber, provided with respective inlet and outlet of the suction chamber preferably is one-way valve.

如本文使用的术语"抽吸元件"和"泵头"表示这样的元件,即抽吸的物质和/或气体在抽吸期间流过这些元件。 As used herein, the term "pumping element" and "head" refers to an element, i.e. the suction of the substance and / or during the suction gas flows through these elements. 因此,术语"抽吸元件"和"泵头"在本文中通常不包括用于驱动抽吸元件和泵头的驱动元件。 Thus, the term "pumping element" and "head" herein generally does not include a driving element for driving the pump head and the pumping element. 术语"泵"和"用于施加负压的机构"表示完成抽吸动作的任何抽吸结构或泵,其中包括用于驱动抽吸元件或泵头的驱动元件。 The term "pump" and "means for applying a negative pressure" means a structure or perform any suction by the sucking operation of the pump, which includes a drive member for driving the suction element or pump head.

在优选实施例中,用于施加负压的机构包括两个可拆卸附接的主要部件,即泵头和驱动单元。 In a preferred embodiment, the means for applying negative pressure comprises two main parts detachably attached, i.e., the pump head and a driving unit. 泵头可以例如包括上述的活塞或隔膜, 并且驱动单元可以包括使泵头往复运动或引起抽吸动作所需的那些元件。 Pump head may for example comprise a piston or diaphragm described above, and may include a driving unit to reciprocate the pump head or cause those elements necessary to cause the pumping operation. 优选地,液密和/或气密密封设置在泵头与驱动单元之间,以便防止气体和/或液体进入驱动单元内。 Preferably, the liquid-tight and / or gas-tight seal is provided between the drive unit and the pump head to prevent gas and / or liquid into the drive unit. 例如,包括象活塞或隔膜之类的泵头可以沿周边密封靠在壁隔板上。 E.g., piston or diaphragm comprising a head as such may be sealed along the periphery against the wall of the separator. 由此可以避免驱动单元污染,或者可以降低驱动单元污染的危险。 Whereby the drive unit to avoid contamination, or may reduce the risk of contamination of the drive unit. 因此,在不同的病人使用该装置中间只有泵头需要消毒。 Thus, the intermediate apparatus different patients require only disinfection head. 可替换地,泵头可以结合到一次性单元中。 Alternatively, the pump head may be incorporated into a disposable unit. 由于 due to

泵头可拆卸地附接到驱动单元上,所以泵头可以容易地消毒和/或更换。 The pump head is removably attached to the drive unit, the head can easily be sterilized and / or replaced.

用于施加负压的才几构可以产生足以从伤口抽走液体的压差,例如 Negative pressure is applied for only a few from the wound configuration may generate sufficient pressure pumped liquid, e.g.

相对于周围大气在10mm Hg至600 mm Hg范围内的负压。 Negative pressure relative to the ambient atmosphere within 10mm Hg to 600 mm Hg range.

当在伤口上放覆盖物时,在伤口部位上便可形成基本气密的密封, 以防止真空泄漏。 When the cover was put on the wound, the wound site can be formed in a substantially airtight seal to prevent vacuum leaks. 将覆盖物放置在伤口上可以形成这样一种密封,使得覆盖物粘附到围绕伤口部位的健康皮肤上,同时在伤口本身上保持气密密封。 The cover was placed over the wound and form a seal, such that the covering adhere to the healthy skin surrounding the wound site, while maintaining an airtight seal over the wound itself. 在本文中,"气密"和"基本上气密"应当理解为是指在伤口处,至少在泵的操作期间可以保持负压。 As used herein, "gas-tight" and "substantially gas-tight" should be understood to mean in the wound, at least during operation of the pump can be kept negative.

伤口覆盖物可以是阻塞的或半阻塞的,例如蒸汽可透过,而水不可透过。 Wound coverings may be blocked or semi-blocked, for example, vapor permeable, but water-impermeable. 在本发明的一个实施例中,通过用半透覆盖箔形成伤口覆盖物使伤口覆盖物成半可透的。 In one embodiment of the present invention, the formation of a wound covering covering the wound by a semi-permeable semipermeable cover foil. 在这种关系中,术语半可透过是指水蒸气可透过。 In this connection, the term semi-permeable water vapor permeable means. 在一个实施例中,伤口覆盖物利用在伤口覆盖物的表面一部分或整个表面上的粘合剂保持就位。 In one embodiment, the wound cover with an adhesive on the surface of the wound covering portion or the entire surface is held in place. 在本发明的另一个实施例中, 伤口覆盖物通过系统所施加的负压保持就位。 In another embodiment of the present invention, the wound covering was applied by vacuum system remains in place.

将用于施加负压的机构设置成两个可拆卸部件具有几个优点。 Means for applying a negative pressure is provided in two detachable parts has several advantages. 泵头通常包括主要的机械部件,而驱动单元还包括较灵敏元件,例如像电动机、电子电路和可能的控制单元。 Typically comprises a head main mechanical components, and the driving unit further comprises a more sensitive element, such as for example an electric motor, an electronic circuit, and the control unit may. 正是在泵头中形成负压,乃至真空。 It is a negative pressure or even a vacuum in the pump head. 由于各部件可相互拆卸,并由于驱动单元对于与潜在带病毒或带细菌的空气或渗出液的接触被隔离,所以驱动单元可重复使用,而无将病毒或细菌可能传染给系统的下一个用户的任何危险。 Because the components can be detached from each other, and since the drive unit is isolated from the contact with air or exudates potential with a virus or with bacteria, the driving unit can be reused without virus or bacteria might be transmitted to the next system any risk of the user. 因此,本发明的系统提供一成本优势,因为系统的主要部件,即用于施加负压的机构的驱动单元可被重复使用。 Thus, the system of the present invention to provide a cost advantage, since the main components of the system, i.e. the drive unit for applying a negative pressure mechanism may be reused. 由于驱动单元因其电子元件通常是最昂贵的部件,所以这个成本优势相对于系统的总成本是相当大的。 Since its drive electronics unit is typically the most expensive component, so the cost advantage relative to the total cost of the system is quite large.

泵头和驱动单元可拆卸地相互附接。 And a head driving unit is detachably attached to each other. 在泵头与驱动单元之间的连接可以釆取几种不同方式。 Connected between the pump head and the drive unit can take several different ways Bian. 本领域的技术人员将会知道提供这种连接的适当方式。 Those skilled in the art will appreciate that a suitable manner to provide such connections.

在本发明的优选实施例中,泵头是一次性的。 In a preferred embodiment of the present invention, the pump head is disposable. 可拆卸泵头是一次性的并且可以更换,而驱动单元由于它既没有与渗出液接触,又未与 Disposable pump head is removable and can be replaced, but since both the drive unit is not in contact with the exudate, and is not yet

潜在带病毒或细菌的空气接触,所以可重复使用。 Potential air contact with viruses or bacteria, it can be reused. 由于泵头主要包括机械和简单部件,所以有可能由比较便宜的材料制造泵头,这降低了泵头的成本。 Since the head and includes a simple mechanical member, it is possible to manufacture the pump head by a relatively inexpensive material, which reduces the cost of the pump head. 泵头可以例如结合到用于从伤口或治疗部位收集流体的罐或容器中。 For example, the pump head can be coupled to the tank or vessel for collecting fluid from a wound or treatment site. 容器可以例如包括连接到导管的进口孔,所述导管提供到治疗部位的流动通路。 The container may comprise, for example, connected to the inlet orifice of the catheter, the catheter to the treatment site to provide a flow path. 另外,容器可以提供连接到泵的进口孔的出口。 In addition, the container can provide outlet to the inlet port of the pump. 在本发明第一方面的装置中和在本发明第二方面的系统中,泵的出口孔优选地连接到排气口上,通过该排气口,抽吸的气体可以被抽吸到周围大气中。 In a first aspect of the present invention, apparatus and system of the second aspect of the present invention, the pump outlet opening is preferably connected to the exhaust port through the exhaust port, the suction gas can be drawn into the surrounding atmosphere . 在本发明第三方面的泵中和在本发明第四方面的系统中,泵的出口孔可以在液体与泵上游的气体分离的情况下或者连接到排气口上,或者在液体不与泵上游的气体分离的情况下连接到用于收集液体的容器上。 In a third aspect of the present invention, the pump and in the system of the fourth aspect of the present invention, the outlet aperture in the case of the pump may be upstream of the pump and the gas liquid separation or connected to the exhaust port, with or without a liquid pump upstream attached to the container for collecting liquid in case of a gas separation. 在这种气体中,排气口优选地设置在泵的下游, 例如在收集容器中。 In such a gas exhaust port is preferably provided downstream of the pump, for example in the collection container.

本文中,术语"上游"和"下游"用来表示相对于流动方向的位置。 As used herein, the terms "upstream" and "downstream" are used to indicate the position relative to the flow direction. 因此,如果第一位置或元件被说成是在第二位置或元件的上游, 这意味着,液体和/或气体的流动在它到达第二位置或元件之前到达第一位置或元件。 Thus, if the position or the first element is said to be upstream of the second position or elements, which means that liquid and / or gas flow reaches the first position or the element before it reaches the second position or elements. 类似地,如果第一位置或元件被说成是在第二位置或元件的下游,这意味着,液体和/或气体的流动在它到达第一位置或元件之前到达第二位置或元件。 Similarly, if the position or the first element is said to be in the second position or a downstream element, which means, liquid and / or gas flow reaches the second position or the first element before it reaches the position or elements.

收集容器可以连接到驱动单元上或与该驱动单元成整体,所述驱动单元装有用于泵的驱动元件。 Collection container can be attached to or integral with the drive unit to the driving unit, the driving element unit with a drive for the pump. 该收集容器优选地是一次性元件,该一次性元件可分离地附接到驱动单元上。 The collecting container is preferably a disposable component, the disposable element is detachably attached to the driving unit.

如上所述,容器可设置成分离机构的整体部分,或者它可设置成分离单元,该分离单元将与分离机构组装。 As described above, the container may be provided as an integral part of the separation mechanism, or it may be provided as separate units, the assembly and the separating unit separating mechanism. 可以设置用于收集和装入从伤口收集的渗出液的容器。 And may be provided in a container for collecting exudates from the wound is collected. 可以设置几种不同的尺寸的容器,以便 May be provided in several different sizes of containers, so that

适应不同用户的不同需要,例如,用于提高灵活性和舒适性的小体积容器、用于大量渗出液和/或将由卧床用户使用的大体积容器。 Adapt to different needs of different users, e.g., for improving the flexibility and comfort of the small volume of the container, for a large number of exudate and / or used by bedridden users bulk container. 容器可以设置几种形式,如本领域的技术人员将知道的那样。 Container may be provided in several forms, as those skilled in the art will know. 它可以设置成箱形的比较刚性的容器,或者可以设置成用较薄材料制成的扁平容器, 使该容器能够弯曲或折叠,以便允许和跟随移动用户的运动。 It may be arranged to form a relatively rigid container box, or may be provided as flat container made of a thin material, so that the container can be bent or folded, so as to allow the user to follow the movement and motion.

在本发明的一个实施例中,分离机构包括具有流体进口、流体出口和气体出口的细长分离部件。 In one embodiment of the present invention, the separating mechanism comprising a fluid inlet, a fluid outlet and an elongate member separate gas outlet.

在本发明的另一个实施例中,分离机构是导管的整体部分。 In another embodiment of the present invention, the separation mechanism is an integral part of the catheter.

一个或多个过滤器优选地设置在排气口中或其上游。 One or more filters are preferably provided in or upstream of the exhaust port. 一个或多个过滤器可以设置在泵头前面,即其上游,并且/或者在其出口处。 One or more filters may be provided in front of the head, i.e. upstream and / or at the outlet thereof. 例如, 可以设置异味(即除臭)过滤器和/或细菌过滤器。 For example, the odor may be provided (i.e., deodorizing) filter and / or bacterial filter. 可以设置任何其它或可替换过滤器,包括异味和/或细菌过滤器,例如一个或多个活性炭 Or you may set any other replaceable filter comprising odor and / or bacterial filter, such as one or more of activated carbon

(碳)过滤器。 (Carbon) filter. 过滤器可以是疏水的和/或疏脂的。 The filter may be hydrophobic and / or lipophobic. 在一个实施例中, 过滤器被置于泵头前面。 In one embodiment, the filter is placed in front of the pump head. 过滤器可以被置于分离机构的气体出口处或靠近该气体出口,以防止液体或固体颗粒进入泵头中。 Filters may be placed at the outlet of the gas separating means or the gas near the outlet to prevent liquid or solid particles from entering the pump head. 在一个实施例中,过滤器是细菌过滤器,该过滤器是疏水的并且优选还是疏脂的。 In one embodiment, the filter is a bacterial filter, the filter is also preferably hydrophobic and lipophobic. 因此,水状和油性液体将在过滤器的表面上形成小珠。 Thus, aqueous and oily liquids will bead up on the surface of the filter. 在正常使用期间,有足够的气流通过过滤器,使得经过过滤器的压降不显著。 During normal use there is sufficient air flow through the filter, so that the pressure drop across the filter is not significant.

在泵头(即抽吸元件)可拆卸地安装到泵的驱动元件上的实施例中, 一个或多个过滤器可以设置在泵头的下游,因为泵头可以容易地用新泵头更换或者为了清洁或消毒临时取下。 In the head (i.e., the suction member) Example on the drive element is detachably mounted to the pump, one or more filters may be provided downstream of the pump head, because the head can be easily replaced with a new head or In order to clean or disinfect temporarily removed. 因此,如果泵头对泵的驱动元件隔绝,则泵头可以被故意污染,并且甚至在一个或多个过滤器失效的情况下,泵的驱动元件也不处于危险中。 Thus, if the pump head to the drive element isolation, the pump head can be intentional contamination, and even in case of failure of one or more filters, the drive elements of the pump is not in danger.

可被包括在分离机构中的容器可以包括至少一个进口和至少一个出口,所述进口用于流体和气体进入容器,所述出口用于气体离开容器进入用于施加负压的机构。 Separating means may be included in the container may include at least one inlet and at least one outlet, the inlet for fluid and gas into the container, the outlet for the gas exiting the vessel into the mechanism for applying a negative pressure. 在这样的实施例中,进口和出口可以相对于容器和泵这样布置,使得在泵的上游将液体与气体分离。 In such an embodiment, the inlet and outlet relative to the container and the pump may be arranged such that the pump upstream of the liquid separated from the gas. 使通过泵抽吸的气体能排出的气体出口应包括在泵中或连接到该泵上。 It sucked by the pump so that the gas can be discharged from the gas outlet in the pump should be included or connected to the pump.

容器可以包括吸收元件,例如用于吸收从伤口抽吸的液体。 The container may include an absorbent element, for example, for absorbing the liquid drawn from the wound. 吸收 absorb

元件可以例如包括胶凝剂、干燥剂或所谓的超级吸收颗粒(SAP)。 Element may include, for example, gelling agents, desiccants, or so-called superabsorbent particles (SAP).

泵头可以是一次性的或可重复使用的,即供多个病人使用。 Pump head may be disposable or reusable, i.e. for a plurality of patients. 例如, 泵头和分离机构可以包括在一个单元中,或者结合到一个单元内。 For example, the pump head and the separation means may be included in a single unit, or incorporated into a cell. 因此,在分离机构包括用于收集抽吸液体的罐或容器的实施例中,例如为了容器的排空或更换,将泵从带有容器的驱动单元上取下。 Thus, the separation mechanism includes a suction tank or collecting embodiment of the liquid container, for example for emptying or replacement of the container, the pump is removed from the drive unit with the container. 由于可 Since

拆卸和一次性泵头与分离机构结合形成一个部件,所以本发明的系统在使用了之后,泵头和分离机构可同时处理掉。 Removal disposable pump head and the separation means to form a member, the system of the present invention after use, the pump head and separating mechanism may be disposed simultaneously. 这是有利的,因为它使系统处理的更简单。 This is advantageous because it allows the system to process easier. 同时,在系统已被使用之后便降低了对于不同病人或用户错误地重复使用用于施加负压的机构的泵头的危险。 Meanwhile, after the system has been used it reduces the risk of a patient or for different user erroneously reused pump head for a negative pressure means applied.

如果抽吸元件或泵头是可重复使用的,则最好能被消毒。 If the suction member or head is reusable, it is preferable to be disinfected. 例如, 泵头可以能够由辐射消毒。 For example, the pump head may be capable of sterilization by the radiation. 在另一个实施例中,泵头可由高压灭菌器消毒。 In another embodiment, the pump head may be autoclaved. 在另一个实施例中,泵头可由蒸汽消毒。 In another embodiment, the pump head can be steam sterilized. 在一个实施例中,泵 In one embodiment, the pump

头可以利用环氧乙烷消毒(ETO消毒)。 Head may be sterilized using ethylene oxide (ETO sterilization). 在又一个实施例中,泵头可通过洗涤消毒。 In yet another embodiment, the pump head can be sterilized by washing. 泵头以及驱动单元可重复使用。 And a head driving unit can be reused. 通过设置可拆卸附接的两个部件,有可能将可能带病毒或细菌的泵头与驱动单元分离,该驱动单元从未与病毒或细菌接触。 By providing two members detachably attached, may be possible with a virus or bacteria separated head drive unit, the driving unit has never been in contact with the virus or bacteria. 在泵头已与驱动单元拆开之后,可以进行适当地清理,以便去除任何可能残留的病毒或细菌。 After the pump head is disassembled and the drive unit, can be suitably cleaned to remove any viruses or bacteria that may remain. 在优选实施例中,泵头主要包括机械部件,而无精密的电子器件。 In a preferred embodiment, the pump head including mechanical components, without sophisticated electronic devices. 因此,它在内部和外部都能有效地清理,且不损害泵头的功能性,并因此使它可重复使用。 Therefore, it can effectively clean up internally and externally, and does not impair the function of the pump head, and therefore it can be reused.

泵头可以永久地结合到容器中,即不可拆卸地包括在其中,或者可以可拆卸地结合到容器里。 Head may be permanently incorporated into the container, i.e. undetachably included therein, or may be removably coupled to the container.

因此将要懂得,用来收集液体的容器以及抽吸元件为了对其更换或清理可以可拆卸地安装。 It will thus be appreciated that a container for collecting the liquid and a suction member for replacement or cleaning thereof may be detachably mounted. 由于设置了如上所述的三个隔间,所以容器可以更换或排空,而不用取下抽吸元件或者不用更换抽吸元件。 Since the three compartments are provided as described above, the container can be replaced or emptied without removing the suction elements or suction elements without replacement. 因为抽吸元件与容器相比构成比较昂贵的元件,所以在不要求更换抽吸元件的情况下,只要更换容器,则本发明提供便宜的泵和系统。 Because the pumping element and the container element constituting the relatively expensive compared to, so without requiring replacement of the suction device, as long as the replacement of the container, the invention provides a system of pumps and inexpensive.

将要理解,在本发明的实施例中,第一隔间构成驱动单元,即装有为使抽吸元件进行抽吸所需的那些元件和组件的单元。 It will be understood, in the embodiment of the present invention, the driving unit constituting the first compartment, i.e. the suction element is provided with means of those elements and components required for suction. 如下面进一步详述的那样,当第二隔间附接到第一和/或第三隔间上时,抽吸元件可以连接成与驱动组件驱动连接。 As described in further detail below, the second compartment when attached to the first and / or third compartment, a suction may be connected to drive element connected to the drive assembly.

在本文中,应当理解,第一、第二及第三隔间构成或包括泵的外壳部件。 In this context, it should be appreciated that the first, second, and third compartment consisting of or comprising a pump housing member. 因此,每个隔间优选地具有至少一个壁部分,当隔间被組装构成泵的外壳时,该壁部分构成泵外壳的外壁。 Accordingly, each compartment preferably having at least one wall part, when the compartment is assembled configuration of the pump housing, the wall portion constituting the outer wall of the pump housing. 在每个隔间内,可以设置一个或几个子隔间,比如容器、抽吸空腔、马达壳体等。 Within each compartment, you may be provided one or more sub-compartment, such as a container, a suction chamber, a motor case or the like.

各隔间可相互分离的附接可以用许多不同的方式实现。 Each compartment can be isolated from each other can be attached in many different ways. 可以设置机械啮合机构,包括例如锁闩和/或锁定结构,用于将各隔间彼此相对可分离地固定。 A mechanical engagement mechanism may be provided, for example, including a latch and / or locking structure, for each compartment opposite detachably fixed to each other. 另外,或者作为替换方案,可以设置磁力机构。 In addition, or as an alternative, the magnetic means may be provided.

如上所述,抽吸元件可以例如包括活塞或隔膜,由此第一隔间可以包括使抽吸元件作往复运动或引起抽吸动作所需的那些元件。 As described above, the suction element may for example comprise a piston or diaphragm, whereby the first compartment comprises a suction member may reciprocate or cause those elements necessary pumping action. 优选地,在抽吸元件与驱动单元之间设置液密和/或气密密封,以便防止气体和/或液体进入驱动单元内。 Preferably, between the suction element and the drive unit is arranged liquid-tight and / or hermetically sealed to prevent gas and / or liquid into the drive unit. 例如,包括诸如活塞或隔膜的泵头可以 For example, the pump head may comprise a piston or diaphragm, such as

沿周边密封,靠在壁隔板上。 Peripherally sealed against the partition wall. 由此可以避免驱动单元污染,或者可以降低驱动单元污染的危险。 Whereby the drive unit to avoid contamination, or may reduce the risk of contamination of the drive unit. 因此,由于当泵将要供另一病人使用时通常更换具有容器的第三隔间,所以在装置供不同病人的使用当中只有第二隔间的泵头需要消毒。 Thus, since when replacing a pump to be supplied to the third compartment having generally a container when another patient use, only the second compartment in the pump head needs to use the device for sterilizing among different patients. 可替换地,第二隔间可以是一次性的,并因此,当泵从一个病人移动到另一个病人时可以将其更换。 Alternatively, the second compartment may be disposable, and therefore, when the pump is moved from one patient to another patient can be replaced.

第一、第二和第三隔间可以按各种构造布置。 First, second and third compartments may be arranged in various configurations. 例如,隔间可以具有普通矩形横截面,使第二隔间的第一表面保持与第一和/或第三隔间的表面齐平。 For example, the compartments may have a generally rectangular cross-section, the first retaining surface of the second surface of the first compartment and / or the third compartment is flush. 与第一表面相对的第二隔间的第二表面可以保持与第一和第三隔间中的另一个的表面齐平。 A second surface opposite the first surface of the second compartment can be maintained with the other surface of the first compartment and the third flush. 可替换地,各隔间可以是通常饼 Alternatively, each compartment may be generally pie

形或弧形的。 Shaped or arcuate. 例如,每个隔间可以形成跨越大约120。 For example, each compartment may be formed spans approximately 120. 角度的饼形或弧形元件,使得每个隔间接触其它隔间中的两个。 Angled or curved pie elements, such that each compartment in contact with the two other compartments. 方便地,第二隔间直接附接到第一隔间上,使得第二隔间到第一隔间的附接产生抽吸元件与第一隔间的马达驱动的驱动配合。 Conveniently, the second compartment is directly attached to the first compartment, the second compartment to the first compartment such that the attachment element generating a suction motor-driven driving engagement with the first compartment.

作为一种安全措施,隔间可以这样构造,即只有当第三隔间从第一和/或第二隔间上拆下时第二隔间才可从第一隔间上拆下。 As a security measure, the compartments may be configured such that only the second compartment from the first compartment before removing the third compartment when detached from the first and / or second compartment. 因此,在设备正在从治疗部位抽吸液体和其它物质时,可以避免拆下抽吸元件。 Thus, while the device is pumping liquids and other substances from the treatment site, to avoid removing the suction member. 在一个实施例中,当第三隔间附接到第二隔间上时,用于从第一隔间分离第二隔间的锁闩被第三隔间覆盖。 In one embodiment, when attached to the second compartment the third compartment, the second compartment for separating the latch from the first compartment is covered by the third compartment. 在另一个实施例中,设置包括例如一个或多个开关和/或发光二极管的电子控制机构,以探测第三隔间是否就位,并且如果就位,则防止取下第二隔间。 In another embodiment, for example, is provided comprising one or more switches and / or electronic control means of the light emitting diode, the third compartment are in place to detect, and, if in place, remove the second compartment is prevented.

泵可以构造成只将气体抽吸通过抽吸元件和/或从中通过抽吸气体和液体。 The pump may be configured to only gas suction by the suction element and / or a gas and a liquid by suction therethrough. 在第一替换方案中,容器具有至少一个进口和至少一个出口,所述进口用于液体和气体进入容器,所述出口用于气体离开容器进入抽吸元件,进口和出口相对于容器和抽吸元件这样布置,使得液体与抽吸元件上游的气体分离。 In a first alternative, the container having at least one inlet and at least one outlet, an inlet for the liquid and gas into the container, the outlet for the gas exiting the container into the suction element, relative to the container inlet and outlet and a suction element is arranged such that the gas and the liquid suction member upstream of the separator. 在这样一个实施例中,泵还包括气体出口,使通过抽吸元件抽吸的气体能从泵中排出。 In such an embodiment, the pump further comprising a gas outlet, the suction by suction from the pump in the gas discharge element. 在这个实施例中, 可以至少基本上防止从伤口抽吸的流体和可能还有固体物质进入泵中,由此可以避免对泵的磨损和泵阻塞的危险。 In this embodiment, the wound may be at least substantially prevented from pumping fluid and possibly hazardous solid material into the pump, whereby the pump can be avoided and wear of the pump blocked.

在其它替换方案中,抽吸元件具有至少一个进口和至少一个出口,所述进口用于液体和气体进入抽吸元件,所述出口用于液体和气体离开抽吸元件,由此抽吸元件的出口孔连接到容器上,使得通过抽吸元件抽吸的液体被输送到容器中。 In another alternative embodiment, the suction element having at least one inlet and at least one outlet, an inlet for the liquid and gas into the suction device, an outlet for the liquid and gas leaving the pumping member, whereby the suction elements an outlet orifice connected to the container such that the container is conveyed to the suction by the liquid suction member. 在这样一个实施例中,泵还包括气体出口,使通过抽吸元件抽吸的气体能从泵中排出。 In such an embodiment, the pump further comprising a gas outlet, the suction by suction from the pump in the gas discharge element. 这个实施例可以适用于泵的元件无阻塞危险的应用场合。 This embodiment can be applied to the pump element blocking a dangerous environment.

从以上说明中将理解到,抽吸元件可以优选地结合到第二隔间中。 It will be understood from the above description, the suction member may preferably be coupled to the second compartment. 优选地,由抽吸元件的往复运动引起收缩和膨胀的抽吸空腔也完全结合到第二隔间中。 Preferably, the suction member by a reciprocating movement caused contraction and expansion of the pumping chamber is completely incorporated into the second compartment. 因此可以实现防止抽吸物质进入并污染第一隔间, 该第一隔间装有泵的驱动组件。 Pumping can be achieved to prevent matter from entering and contaminating the first compartment, the first compartment is equipped with a pump drive assembly.

虽然为避免污染装有泵的驱动组件的第一隔间可在隔间的任一个中设置气体出口,但优选的是,使气体出口设在第二或第三隔间中。 Although the first compartment to avoid contamination with the pump drive assembly may be provided at the gas outlet in any one compartment, it is preferred that the gas outlet provided in the second or third compartment. 如下面描述的那样,可以设置一个或多个过滤器。 As will be described below, may be provided one or more filters.

在一些实施例中,其中,抽吸元件包括泵头,在泵操作期间通过该泵头从治疗部位抽吸气体和/或液体,在泵头与第一隔间之间优选地设置液体和/或气体密封,以便防止气体和/或液体进入第一隔间。 In some embodiments, wherein the suction element comprises a head, a suction gas and / or liquid from the treatment site during pump operation through the pump head, and a liquid disposed preferably between the first compartment and the pump head / or a gas seal to prevent gas and / or liquid into the first compartment. 密封可以例如由抽吸元件靠在第二隔间上密封达到,所述抽吸元件例如由隔膜或活塞构成。 May for example be sealed to seal against a second compartment by a suction element, the suction element is constituted by a diaphragm or piston. 使得当以操作构型附接到第一和/或第三隔间上时第二隔间的抽吸空腔被密封,以防止抽吸物质从第二隔间排到第一隔间。 In such operating configuration when attached to the first and / or second compartment the third compartment of the suction cavity is sealed to prevent smoking material discharged from the second compartment the first compartment.

可替换地,抽吸元件可以包括蠕动元件,该蠕动元件通过装在第二隔间中的管的流动横截面的连续收缩和膨胀施加负压。 Alternatively, the element may comprise a peristaltic pumping element, the peristaltic flow tube element is mounted in the second compartment through the cross section contraction and expansion of a continuous negative pressure is applied. 管的收缩和膨胀可以例如由可转动元件实现,该可转动元件具有一个或多个作用在管外表面的突出部分,由此使管的流动横截面接连收缩和膨胀,这种可转动元件包括在第一隔间中,或者至少由第一隔间中的驱动组件驱动。 Contraction and expansion of the tube can be realized by the rotatable member, the rotatable member having a projecting portion or a plurality of acting outside the tube surface, whereby the flow cross section of the tube successive contraction and expansion, which may include a rotatable member in the first compartment, or driven by the first drive assembly compartment at least.

可以设置用于探测在伤口覆盖物内的负压的压力检测元件。 It may be provided for detecting a pressure in the negative pressure detecting element was wound cover. 可替换地或另外,可以设置用于探测在容器中的负压的压力检测元件。 Alternatively or additionally, the pressure sensing element may be provided for detecting the negative pressure in the container. 这种压力检测元件可以连接到控制泵马达的操作的控制单元上,以保证在治疗部位保持所需的负压。 This pressure detecting element can be connected to the control unit controls the pump motor operation, at the treatment site to ensure maintaining a desired negative pressure. 在一个实施例中,压力检测元件可以设 In one embodiment, the pressure sensing element may be provided

置在第一隔间中。 Disposed in the first compartment. 因此,压力检测元件的存在不会使在大多数实施例中是一次性元件的第二和第三隔间变得不必要地昂贵。 Thus, there is a pressure detecting element does not cause in most embodiments, the second and the third compartment is a disposable element is unnecessarily costly.

在压力检测元件设在第一隔间中的情况下,该压力检测元件可以布置在至少部分贯穿第二隔间的压力导管的端部处或其附近,使得不需要分离的外部导管或管进入第一隔间。 In the case where the pressure detecting element is provided in the first compartment, the pressure detecting element can be arranged at or near the end of the second compartment at least partially through the pressure conduit, so that no separate external catheter or tube into the The first compartment. 这可以减少将要组装的部件数量,便于泵的操作,并且减少第一隔间污染的危险。 This may reduce the number of parts to be assembled, to facilitate operation of the pump, the first compartment and reduce the risk of contamination.

压力导管可以通到容器或者通到第二或第三隔间的压力输入端口中。 Pressure conduit or to the container can pass through the second or third compartment to a pressure input port. 在后者的替换方案中,压力输入端口可以连接到治疗部位上,例如连接到由伤口覆盖物覆盖的伤口上,在这种情况下,压力检测元件探测治疗部位的压力。 In the latter alternative, the pressure input port may be connected to the treatment site, for example to a wound covering covering the wound, in this case, the pressure sensing element to detect pressure treatment site. 同样,可以探测系统的其它部件中的压力。 Similarly, the pressure may be detected in other components of system. 在第一可替换方案中,压力检测元件探测容器中的压力,该压力可以等于或至少代表治疗部位的压力。 In a first alternative embodiment, the pressure detecting element detecting the pressure vessel, the pressure may be a pressure equal to or representative of at least a treatment site.

在其它实施例中,压力检测元件设置在第二隔间中。 In other embodiments, the pressure sensing element is disposed in the second compartment.

泵还可以包括基本上气密和/或液密阻挡层,用于防止被压力检测元件的气体和/或液体污染,下面将进一步详细描述。 The pump may further include a substantially gas-tight and / or liquid-tight barrier layer for preventing gas pressure detecting element / contamination of the liquid, and will be described in further detail below, or.

在本发明中,可偏转件(deflectable member )可以相对于由伤口覆盖物形成的封闭物这样布置,使得在外界压力与由用于施加负压的机构施加的负压之间的压差可以引起可偏转件偏转。 In the present invention, the deflectable member (deflectable member) may be arranged with respect to the covering formed by the wound closure, such that the pressure difference between the negative external pressure is applied by means for applying a negative pressure may cause deflection of the deflectable member. 压力检测装置可以位于由伤口覆盖物形成的封闭物外面,并且布置成响应于压力或可偏转件的偏转提供信号,可偏转件在传感器与封闭物之间形成基本上气密的阻挡层。 Pressure detecting means may be located outside the closure formed by the wound coverings, and arranged to provide a signal in response to pressure or deflection of the deflectable member, the deflectable element between the sensor and form a substantially airtight closure of the barrier layer.

因此,提供一些系统,其中,可偏转件将压力检测装置与在封闭物中的渗出液分离。 Accordingly, some systems, wherein the deflectable member and the pressure detecting means in a closed effusion was separated.

由于可偏转件不仅偏转并由此便于测量压力,而且还将压力检测装置与渗出液分离,所以降低了驱动单元污染的危险,并且使检测装置可以重复使用多次且不用消毒。 Since not only deflect the deflectable member and thereby facilitate the measured pressure, but also pressure detecting means and separation exudate, so reducing the risk of contamination of the drive unit, and the detection means may be reused multiple times and no disinfection. 因此,在增加安全性的同时可以降低成本。 Therefore, increasing security while reducing cost. 优选地,可偏转件形成对细菌、病毒、气体和液体的阻挡层。 Preferably, the deflectable member forms a barrier to bacteria, viruses, gases and liquids.

泵可以包括至少一个一次性部件和至少一个耐用(即可重复使用) 部件,所述一次性部件包括例如用于收集从伤口抽吸的液体的容器, The pump may comprise at least one member and at least one disposable and durable (i.e. reusable) components, for example, the disposable component comprises a container for collecting the liquid drawn from the wound,

所述耐用部件包括例如用于泵的驱动组件。 The durable portion comprising a drive assembly for a pump, for example. 在这样的实施例中,压力检测装置优选地布置在耐用部件中,而可偏转件优选地布置在一次性部件内,由此既降低了成本又减少了污染危险。 In such an embodiment, the pressure detecting means is preferably arranged in the durable part, and the deflectable member is preferably disposed within the disposable part, thereby reducing both the cost and reducing the risk of contamination.

通常,在治疗期间可能被污染的系统的伤口覆盖物、可偏转件和其它组件可以是一次性的,这意味着,组件被设计成相对于例如启动泵的可重复使用的驱动单元在短的时间周期内使用。 In general, during the treatment of wounds that may be contaminated with a covering system, the deflectable member and the other components may be disposable, which means that the assembly is designed to activate the pump with respect to the drive unit, for example, may be re-used in a short use the time period. 在放置伤口覆盖物时,在伤口部位上可以形成基本上气密密封,以防止真空泄漏。 When placing the wound covering, the wound site may be formed in a substantially gas-tight seal to prevent vacuum leaks. 将覆盖物放置在伤口上可以形成这样一种密封,使得覆盖物粘附到围绕伤口部位的健康皮肤上,同时在伤口本身上保持气密密封。 The cover was placed over the wound and form a seal, such that the covering adhere to the healthy skin surrounding the wound site, while maintaining an airtight seal over the wound itself. 在本文中, "气密"和"基本上气密"应当理解成是指至少在泵的操作期间在伤口上可以保持负压。 As used herein, "gas-tight" and "substantially gas-tight" should be understood to mean at least during operation of the pump may be maintained at a negative pressure on the wound.

可偏转件应当优选是基本上气密的,并由此防止细菌和渗出液通常通过隔膜扩散。 Deflectable member should preferably be substantially air tight, and thereby generally prevent bacteria and exudate through the membrane diffusion. 可偏转件可以由对空气和其它气体显著不透过的材料制成。 The deflectable member may be made of a material of significant air and other gas impermeable. 由于没有在较长时期内对气体完全不透过的聚合物,所以本文所用的术语"显著不透过,,表示,在用偏转件一次治疗期间的渗透作用对于测量是可忽略的。可偏转件可以特别对细菌基本上是不透过 Since the polymer in the longer term does not completely impermeable to gases, so as used herein, the term "substantially impermeable ,, said infiltration during treatment with a deflecting member for measurement is negligible. Deflectable It may in particular member is substantially impervious to bacteria

的。 of. 细菌通常具有大约0.2 pm的直径。 Bacteria generally have a diameter of about 0.2 pm. 因此,阻挡层可以对大于0.02 Hm的颗粒基本上不透过,以达到大约IO的安全因数。 Accordingly, the barrier layer may be substantially impermeable to particles larger than 0.02 Hm in order to achieve the safety factor of approximately IO. 可偏转件也可以不被病毒透过,并因此在单次使用环境与周围环境之间起到阻挡层的作用。 The deflectable member may not be transmitted through the virus, and thus functions as a barrier layer between the single use environment and the surrounding environment. 尽管尺寸小(20-300nm)病毒将不能穿过象不透过偏转件之类的固体材料。 While the small size (20-300 nm) as a virus can not pass through the impermeable solid material deflecting member or the like. 材料的一个示例是供实验室手套用的丁腈橡胶。 One example material is a nitrile rubber gloves for laboratory use. 可偏转件可以由柔性聚合物材料制成。 The deflectable member may be made of a flexible polymeric material. 可以选择象PE、 PP和PVC之类的塑性材料,因为这些材料通常便宜,并且适合于注射模制或吹塑模制。 Plastic material may be selected PE, PP and PVC as such, because these materials are generally less expensive, and is suitable for injection molding or blow molding. 可偏转件也可以由选自如下种类的材料制作,其中包括:热塑性弹性体(TPU、 SIS、 SBS及SEBS)、象合成和天然橡胶之类的热固性或硫化弹性体、胶乳、玻璃、金属和陶瓷。 The deflectable member may be made of a material selected from the classes, including: thermoplastic elastomers (TPU, SIS, SBS and SEBS), synthetic and natural rubber as such or vulcanized thermoset elastomer, latex, glass, metal, and ceramics. 在任何情况下,可偏转件应当设计成在上述范围的压差时偏转,即10-600 mmHg,乃至在10-200 mmHg的范围内。 In any case, the deflectable member should be designed to deflect when pressure above range, i.e. 10-600 mmHg, and even in the range of 10-200 mmHg.

关于可偏转件及其要求的实施例目前考虑的事项同样也示用于抽 Matters regarding embodiments presently contemplated embodiment the deflectable member and is also required for drawing illustrating

吸元件(即泵头)的实施例,比如供在蠕动泵中用的管、供在隔膜泵 Example absorbing element (i.e., pump head), such as in the supply tube by a peristaltic pump, a diaphragm pump for use in

中用的隔膜或供在活塞泵中用的活塞。 Used for the diaphragm or piston pump with a piston. 通常,偏转的原理可以基于: In general, the principle of deflection can be based on:

i) 薄膜的弹性膨胀,或 i) expansion of the elastic film, or

ii) 可偏转件的形状的改变,即例如通过材料的弯曲,比如通过弹性弯曲,或 ii) a change in the shape of the deflector, i.e., for example, by bending the material, such as by elastic bending, or

iii) 可偏转件的一个元件相对于另一个元件的运动。 iii) a deflector element may be moved relative to the other element.

Ad i)如果偏转基于弹性膨胀,则可偏转件可以包括比较薄的薄 Ad i) if deflection based on the elastic expansion can be relatively thin deflector member may comprise a thin

膜或隔膜,例如在包囊上伸展的、或在管的开端上伸展的、或在两个 Membrane or diaphragm, for example, extending in the encapsulated, extended, or in the beginning of the tube, or in two

或更多个间隔圆盘上伸展并因此形成缸中柔性壁等的气球或隔膜,可偏转件与封闭物流体连通。 Or more spaced disks stretching the thus formed balloon and the flexible wall or membrane cylinder or the like, the deflectable member in communication with the closing fluids.

Adii)如果偏转基于材料的弯曲,则可偏转件可以包括在一个方向上根据压差能膨胀和收缩的波紋管形件,或者可偏转件可以包括Bourbon管,即根据内部压力改变其形状的管。 Adii) If the material based on the bending deflection, the deflection member may be a pressure differential comprising a collapsible and expandable bellows-shaped member, or may comprise a deflectable member Bourbon tube, i.e., changes its shape in accordance with the internal pressure of the tube in one direction .

Ad iii).如果偏转基于彼此相对运动的元件,则元件可以包括在管中的"滚动隔膜"或活塞和缸装置或液体串(string)。 Ad iii). If the deflection element relative to each other based on the element may be included in tube "rolling diaphragm" or the piston and cylinder device or a liquid string (string).

与偏转的原理无关,对于一定压差的偏转程度,即可偏转件克服偏转的阻力可以由选择材料的性质、可偏转件的尺寸控制,或者由设置影响偏转的结构的分离力控制。 And principle independent of deflection, the degree of deflection of a certain pressure, to overcome the deflecting members resistance can be deflected by the nature of the choice of material, you can control the size of the deflector, or the separation force provided by the deflection control structure impact. 作为这样一种结构的示例,可以设置弹簧,例如螺旋盘簧来影响偏转。 As an example of such a structure, a spring may be provided, such as a helical coil spring to affect deflection.

可偏转件可以以两种不同方式使用: The deflectable member may be used in two different ways:

a) 作为被动件,其偏转而没有任何显著阻力,并且仅作为封闭物与压力检测装置之间的气密阻挡层,或者 a) as a passive member, deflection without any significant resistance, and only as a hermetic barrier between the closure and the pressure detecting means, or

b) 作为主动件,其偏转与在伤口封闭物中的压力平衡并且通过检测装置探测,因此,可偏转件是压力检测装置的一部分。 b) as an active element, which is deflected in the pressure balance in wound closure and by detecting means to detect, and therefore, the deflectable member is a part of the pressure detecting means.

Ad a)可偏转件经测量导管或小室连接到与封闭物相对的侧部上的压力传感器上。 Ad a) a deflectable member connected to the pressure sensor on the side opposite to the closure portion or chamber via the measuring tube. 由于可偏转件运动没有显著阻力或几乎无应力地偏转,所以它将占据在可偏转件的两侧达到相同压力的位置,使得压力能通过阻挡层用任何已知种类的压力传感器准确地测量。 Since there is no movement of the deflectable member or almost no significant resistance to deflection stress, so it can occupy both sides of the deflector to achieve the same pressure position, the pressure sensor such that the pressure barrier layer by any known kind accurately.

通常,传感器可以包括任何类型的传感器,这种传感器能够测量上述种类的压差。 Typically, the sensor may comprise any type of sensor, such a sensor capable of measuring pressure of the above kind. 例如,传感器可以包括选自如下种类的元件: -应变仪元件, -压电电阻元件, -压电元件, -Bourbon管, For example, the sensor may comprise components selected from the species: - a strain gauge element, - piezoresistance element, - a piezoelectric element, -Bourbon tube,

-微机电系统(MEMS或固态MEMS ), -振动元件(硅谐振), -可变电容元件,和-微皮拉尼真空计。 - micro-electromechanical systems (MEMS solid or the MEMS), - a vibrating element (Silicon Resonant), - a variable capacitance element, and - a micro Pirani gauge.

Adb)压力检测装置可以位于封闭物外面,并且适合于根据可偏转件的偏转提供信号。 Adb) pressure detecting means may be located outside the closure, and is adapted to provide a signal in accordance with the deflection of the deflectable member. 通常,检测装置可以是任何类型的,它能够测量尺寸、距离、偏转、运动或力。 Typically, the detection may be any type of device, it is possible to measure the size, distance, deflection, motion or force.

应用的检测原理可以基于在检测装置与可偏转件之间的接触,即接触测量,或者它可以不以直接接触测量,即无接触测量。 Detection principle can be applied based on the contact between the deflectable member and the detecting means, i.e., contact measurement, or it may not be in direct contact measurement, i.e., non-contact measurement. 用于接触检测的检测装置可以包括选自如下种类的元件: -压电电阻元件, -压电元件, -振动元件(硅谐振), -可变电容元件,和-偏转的机械测量,例如采用: Detecting means for detecting the contact may include a kind of element selected from: - piezoresistive element, - a piezoelectric element, - a vibration member (resonator silicon), - a variable capacitance element, and - measuring mechanical deflection, using e.g. :

-应变d义元件, - d strain sense element,

-线性运动位置传感器, - linear motion position sensor,

-电位器, - potentiometer,

-力传感器,或 - force sensor, or

-力敏感电阻器元件(FSR)。 - force-sensitive resistive elements (FSR). 无接触测量可以基于: -超声波反射, Contactless measurement can be based on: - ultrasound reflection,

-反射光(IR-LED/激光二极管), - reflected light (IR-LED / laser diode),

-三角测量(IR-LED/激光二极管和PSD-位置检测装置), - triangulation (IR-LED / laser diode and a position detecting means PSD-),

-差动可变磁阻转换器(DVRT或LVDT-线圏中具有铁芯)。 - variable reluctance differential transducer (DVRT LVDT- or rings of wire having a core). 在任何情况下,信号优选是电信号,这种信号能用来经指示仪表或显示器监视封闭物中的负压和/或控制泵,以提供所需的负压。 In any case, the signal is preferably an electrical signal, such a signal can be used by the monitor or display instrument indicating the negative pressure in the closure and / or control the pump to provide the desired negative pressure.

传感器或检测装置的成本与一次性组件的成本相比往往较高。 Cost Cost of the disposable sensor assembly or the detection device is often higher compared. 而且一次性传感器包括需要电源的电子部件和用于将信号传送到耐用(可重复使用)显示器或控制单元的机构。 And disposable sensors comprising a power supply and electronics needed for transmitting the signal to the durable (reusable) display means or a control unit. 因此,可以有利的是,使检测装置与可偏转件分离,并因此使可偏转件在每次使用之后能被处理。 Thus, it may be advantageous that the detection means is separated from the deflectable member, and thus the deflectable member can be handled after each use. 所以可偏转件优选地可以密封方式可拆卸地连接到压力传感器上, 或者可以布置成接合接触检测装置或者相对于无接触测量装置例如通过搭扣连接系统接合在正确位置,这种搭扣连接系统以容易的方式便于可偏转件相对于检测装置正确定位。 Therefore, the deflectable member may preferably be detachably connected in a sealed manner to the pressure sensor, or may be arranged to engage or contact detecting means with respect to the non-contact measuring apparatus, for example by a snap connection system engaged in the correct position, this snap connection system facilitate easy manner with respect to the deflectable member means detecting correct positioning. 为了保证正确的测量,可以布置连接系统,防止泵的使用,除非可偏转件的位置相对于传感器是正确的。 To ensure correct measurement, the connection system can be arranged to prevent the use of a pump, unless the deflectable member relative to the sensor position is correct.

在一个实施例中,可偏转件形成伤口覆盖物的壁部分,或者形成与封闭物流体连通的元件部分,例如形成从封闭物延伸的管的部分。 In one embodiment, the deflectable member forms a wall portion of the wound covering, or forming part of the closure member in fluid communication, for example, the tube portion extending from the closed formation.

可偏转件可以形成伤口覆盖物的部分,或者可偏转件可以形成与封闭物流体连通的压力信号导管的壁部分。 Deflectable member may form part of a wound covering, or deflectable wall may be formed with the closure portion of the pressure signal conduit in fluid communication. 压力信号导管使传感器能远离伤口设置,并由此传感器可以被包括在用于启动泵的驱动单元内。 Pressure signal conduit the sensor can be disposed away from the wound, and thus the sensor may be included for actuating the pump drive unit.

压力信号导管可以由医用管形成或嵌入其中。 Pressure signal conduit may be formed or embedded in a medical tube. 在一个实施例中, 管形成几个腔,其中, 一个腔形成压力信号导管,而另一个腔形成排放导管。 In one embodiment, the tube is formed of several cavities, wherein a signal pressure conduit chamber is formed, and the cavity forming the other discharge conduit. 作为多腔管使用的替换方案,压力信号导管和排放导管可以由单个医用管形成,并且各管可以接合,用来增强系统的处理和用来增强伤口覆盖物、泵及压力传感器的连接。 As an alternative to the multi-lumen tube is used, the signal pressure conduit and the discharge conduit may be formed of a single medical tube, and the tubes may be joined, to enhance the processing system and connected to enhance wound coverings, pumps and pressure sensors. 为了进一步增强部件的连接,多腔管或单腔管可以包括耦合机构,该耦合机构在一次耦合动作中将泵连接到排放导管上和将压力信号导管连接到传感器上。 To further enhance the connection member, single or multi-lumen tube lumen may include a coupling mechanism, the coupling mechanism in the operation of a pump in the discharge conduit connected to the coupling and the conduit connecting the pressure signal to the sensor. 类似地, 通过单次分离动作两个管可以得到分离。 Similarly, it can be separated by a single separation operation of the two tubes.

由于信号导管与排放导管相反仅传送压力信号,而不是流体,所以象渗出液之类的液体物质不处理来进入压力信号导管中。 Since the signal conduit and the discharge conduit opposite to transmit only pressure signals, instead of the fluid, so as exudate liquid material or the like into the pressure signals without processing conduit. 然而,为了增强系统的可靠性,信号导管可以形成进入封闭物的进口,该进口 However, in order to enhance reliability of the system, the signal conduit may be formed into the closure of the inlet, the inlet

包括防止液体物质和渗出液进入信号导管的分离结构。 It includes preventing the liquid substance into the exudate and the signal separation structure of the catheter. 该分离结构可以例如是高度柔性阻挡层,例如上述的可偏转件或第二"无应力"可偏转件。 The separation structure may be, for example, highly flexible barrier layer, such as the aforementioned second deflectable member or "unstressed" deflectable member.

为了提供快速和精确的信号传递并限制可偏转件的偏转或运动, 优选的是,提供具有较小体积的压力信号导管,优选地小于排放导管的体积。 In order to provide fast and accurate signal transmission and limit movement or deflection of deflectable member, preferably, the pressure signal to provide a catheter having a smaller volume, preferably less than the volume of the discharge conduit. 因此,信号导管可以优选地具有比排放导管小的横截面面积。 Thus, the signal conduit may preferably have a smaller cross-sectional area than the exhaust conduit.

在一个实施例中,可偏转件是连接到测量导管的基本上无应力的可偏转部分,并且检测装置是压力传感器。 In one embodiment, the deflectable member is connected to the substantially unstressed deflectable portion of the measuring tube, and the detecting means is a pressure sensor.

在另一个实施例中,可偏转件包括基本上无应力的可偏转部分和提供力的弹簧结构,该结构可以是可偏转件的整体部分或分离元件, 并且检测装置是无接触距离传感器。 In another embodiment, the deflectable member may comprise a substantially unstressed and deflectable spring force providing moiety, the structure may be an integral part of the deflectable member or the separating element, and the detecting means is a non-contact distance sensor.

结构可以应用于参照图l-6所述的系统中。 Structure may be applied with reference to FIGS. L-6 in the system.

图7和8是本发明第一方面的装置实施例的两个垂直平面的横剖视图。 7 and FIG. 8 is a cross sectional view of two embodiments of the vertical plane of the first aspect of the present invention. 装置包括三个隔间,即第一隔间101、第二隔间102和第三隔间103。 Means comprising three compartments, namely a first compartment 101 and second compartment 102 and third compartment 103. 如下面进一步详述的那样,第一隔间101装有使第二隔间102 的抽吸元件从伤口抽吸渗出液的驱动组件。 As described in further detail above, the first compartment of the second compartment 101 with the suction member drive assembly exudate drawn from the wound 102. 第三隔间103包括用于收集从伤口抽吸的液体的收集容器105。 The third compartment 103 includes a collection vessel for collecting the liquid 105 is drawn from the wound.

通常有利的是,不管在抽吸空腔106的上游还是下游在第三隔间中可以设置任何的过滤器。 It is generally advantageous, whether in the suction cavity upstream or downstream in the third compartment may be provided in any of the filter 106. 因此,当更换第三隔间时设置新的过滤器, 由此延长了第二隔间102的寿命。 Accordingly, a new filter setting when changing the third compartment, thereby prolonging the life of the second compartment 102.

由隔膜104的往复运动产生的抽吸作用在第三隔间103的收集容器105中形成负压。 Suction generated by the reciprocating motion of the diaphragm 104 a negative pressure in the collecting container 105 in the third compartment 103. 收集容器105经由排放导管128连接到伤口(未示出)上,由此在伤口部位产生负压。 Collection container 105 via a discharge conduit 128 is connected to the wound (not shown), thereby generating a negative pressure at the wound site. 设置压力导管130,以经过贯穿第二和第三隔间102、 103的压力端口使伤口部位与压力检测元件132连接。 Pressure conduit 130 is provided to penetrate through the second and third pressure compartment 102, a port 103 so that the wound site 132 is connected to the pressure detecting element. 优选地设置可偏转件132*,该可偏转件132*在传感器132 的上游,即在传感器132与伤口封闭物(未示出)之间形成基本上气密阻挡层。 Preferably, the deflectable member 132 provided * * The deflectable member 132 upstream of the sensor 132, i.e., the sensor 132 and the wound closure (not shown) forming a substantially airtight barrier between. 可偏转件和压力传感器132可以如下面参照图15-28所述的那样具体实施。 The deflectable member and the pressure sensor 132 may be implemented as specific as described below with reference to FIGS. 15-28.

导管128和130可以方^更地由多腔管构成,比如双腔管。 Conduits 128 and 130 may be square ^ more multi-lumen tube configuration, such as double lumen tubing. 然而, 还设想,对两个导管可以设置两个分离的管,在这两个导管中,压力导管可以直接延伸到第二隔间102中,乃至直接延伸到第一隔间101 中。 However, it is also contemplated that the two conduits may be provided for two separate tubes, these two conduits, pressure conduit may extend directly to the second compartment 102, and even extending into the first compartment 101 directly. 然而,为了减小装在第一隔间101中的元件(包括压力传感器l32) 受到污染的危险,将压力优选地连接到第二或第三隔间上。 However, in order to reduce the element mounted in the first compartment 101 (including a pressure sensor L32) risk of contamination, the pressure is preferably connected to the second or third compartment.
