[0024] 请一并参考图2与图3,气体过滤器包括过滤器主体110、开设在过滤器主体110上与外界空气相连通的气体净化仓120、设置在气体净化仓120内吸附气体中杂质的活性炭及将负压源的出气口与气体净化仓120气路连通的负压源接口140。 [0024] Please refer to FIGS. 2 and 3, the gas filter 110 includes a filter body, the filter is opened in the main body 110 communicates with the outside air gas purification cartridge 120, 120 is disposed within the gas adsorption gas purification cartridge activated carbon and impurity source of negative pressure and a gas outlet port interface to the negative pressure source purge gas passage 120 communicates the bin 140.

[0025]其中,过滤器主体110可以固定在壳体上,也可以为壳体的一部分。 [0025] wherein the filter body 110 can be fixed to the housing, it may be a part of the housing. 为了使壳体比较平整,当采用过滤器主体110固定在壳体上的形式时,可以在壳体上挖出用来容置过滤器主体110的容置空间,过滤器主体110可以采用卡合或者螺丝锁附等方式镶嵌固定在壳体的容置空间内。 In order to make the housing relatively flat, when in the form of a filter body 110 is fixed to the housing, the housing may be dug to accommodate the filter housing space 110 of the main body, the filter body 110 can be engaged using attachment screws or the like insert-fixed in the accommodating space of the housing. 此处的滤器主体110为壳体的一部分。 Filter body 110 here is a part of the housing.

[0026]另外,过滤器主体110上设有用于容置电源线的卡槽170。 [0026] Further, a slot for receiving the power source line 170 on the filter body 110. 卡槽170除了具有容置电源线的作用外,还可以设计成与气体净化仓120相连通的形式,这样经过气体净化仓120净化后的气体可以从卡槽170散发出去。 In addition to the slot 170 has a function of receiving external power supply line, may also be designed to form the gas purification cartridge (120) in communication, such purge gas through the gas purge bin 120 from the slot 170 can be dissipated. 该卡槽170也就具有作为气体散发通道的作用。 The slot 170 also has a function as a gas distributing passage.

[0027]本实施例中,负压伤口治疗设备的气体净化仓120内设有气体过滤通道130。 [0027] In this embodiment, negative pressure wound therapy device gas purification filter cartridge 120 equipped with a gas passage 130. 气体过滤通道130内设有活性炭。 Gas passage 130 equipped with activated charcoal filter. 从负压源出来的气体经过负压源接口140后达到气体过滤通道130,并经过气体过滤通道130到达气体净化仓120内。 Out from the negative pressure source through a gas pressure source 140 gas to reach the interface channel filter 130, and filtered through a gas channel 130 within the cartridge 120 reaches the gas purification. 活性炭具有吸附和过滤的作用,经过气体过滤通道130的气体将得到净化,从而去除异味和细菌等。 Activated carbon adsorption and filtration effect, the gas through the gas passage 130 will be filtered purified to remove odors and bacteria. 在本实施例中,负压伤口治疗设备的气体过滤通道130的数量为多个。 In the present embodiment, negative pressure wound therapy device of the gas filter 130 is a plurality of number of channels. 这些气体过滤通道130均与负压源接口140相气路连通。 The filtered gas passages 130 are in communication with a vacuum source interface 140 gas path. 气体达到负压源接口140后再经过气体过滤通道130的过滤后到达气体净化仓120,最后再排放到外界空气中。 Interface to the source of negative pressure gas reaches the gas passage 140 and then through the filter 130 filters the gas purge bin 120, and finally discharged to the outside air.

[0028]另外,在本实施例中,这些气体过滤通道130是相互并联在一起的。 [0028] Further, in the present embodiment, the channel 130 is a gas filter in parallel with each other. 也就是说,每个气体过滤通道130的一端均与负压源接口140直接相连,另一端均与气体净化仓120直接相连。 That is, one end of each of the gas passages 130 are filtered and the negative pressure source interface 140 is directly connected to the other end of the cartridge 120 are directly connected to the gas purification. 为了使气体净化效果更好,也可以采用将这些气体过滤通道130串联在一起的方式。 In order to better gas purification, gas filter these passages 130 connected together in series manner may be employed. 即,将这些气体过滤通道130首尾相接,将处于首尾位置的两个气体过滤通道130分别与负压源接口140和气体净化仓120直接相连。 I.e. two gas filtration passages 130, passage 130 of these gas filter connected end to end, end to end position in the cartridge 120 are directly connected to a vacuum source interface 140 and gas purification. 这样从负压源接口140进来的气体可以经过多级过滤,从而达到提升空气净化效果的作用。 Thus the gas coming from the pressure source 140 may be subjected to multi-stage filtration interfaces, so as to enhance the effect of the air purifying effect.

[0029]请参考图3,气体过滤器100的背面可以设有多个通气接口 180。 [0029] Please refer to FIG. 3, the back of the gas filter 100 may be provided with a plurality of ventilation interface 180. 在本实施例中,这些通气接口180的数量为四个。 In the present embodiment, the vent 180 is an interface number four. 这四个通气接口180分别与单向阀、负压源、集液盒和传感器相连。 These four ventilation interface 180 are connected to the check valve, the negative pressure source, and a sensor cartridge header. 单向阀、负压源、集液盒和传感器在该负压伤口治疗设备中所起的作用和相互间的连接关系与常用的负压伤口治疗设备相同,此处不再赘述。 A one-way valve, the same connections between the negative pressure source, and a sensor cartridge header in the negative pressure wound therapy device and the role of each other with a common negative pressure wound treatment apparatus is not repeated here.

[0030]请参考图4,气体过滤器100还包括盖在气体净化仓120上的盖板150。 [0030] Please refer to FIG 4, the gas filter 100 further includes a cover plate 150 on the cover 120 of the cartridge purge gas. 盖板150上设有将气体净化仓120与外界空气相连通的出气孔160。 The cover plate 150 is provided with a gas purge bin 120 communicates with the outside air outlet hole 160. 盖板可以采用卡合固定或者螺丝所附的方式固定在气体过滤器100的过滤器主体110上。 The cover plate may be fixed or employ screw engagement is fixed to the attached body 110 filter the gas filter 100. 另外,盖板150上也可以不设置出气孔160,此时,经过净化后的气体可以经由用来容置电源线的卡槽170排出。 Further, the cover plate 150 may not be provided a hole 160, at this time, may be discharged for accommodating slot 170 through the power supply line via the gas purge.

[0031 ]负压伤口治疗设备在使用过程中,伤口处套件将覆盖在伤口处,然后控制器将控制负压源提供用于抽吸伤口渗出液的负压。 [0031] The negative pressure wound therapy device during use, will cover the wound at the wound package, then the controller will control the negative pressure source for sucking negative pressure wound exudate. 同时,负压伤口治疗设备在工作过程中会将伤口处的气体和液体抽走,其中液体将进入集液盒,气体将由负压源抽至负压源接口140处。 Meanwhile, negative pressure wound therapy device in the gas and the liquid will be pumped from the wound during operation, wherein the liquid enters the liquid collecting box, a source of negative pressure by pumping the gas to a pressure source at the interface 140. 接着,气体将到达气体过滤通道130,经过气体过滤通道130的过滤作用到达气体净化仓120。 Next, the filtered gas to the gas passage 130, through the gas filtration filter 130 reaches the gas passage purge bin 120. 最后经由卡槽170或者盖板150上的出气孔160排出气体净化仓120至外界空气中。 Finally, 160 exhaust gas purification cartridge (120) to the ambient air via the outlet hole 170 or slot 150 on the cap plate. 由于负压伤口治疗设备所排出到外界空气中的气体经过了气体过滤通道130内的活性炭的吸附净化作用,所以由伤口处产生的带有异味、细菌的气体得到了净化,异味和细菌得到了去除。 Since the negative pressure wound therapy device discharged to the outside air through the gas gas purification activated carbon adsorption filter in the passage 130, is generated by the wound with the smell, the gas has been purified bacteria, odors and bacteria obtained removed. 工作人员和患者在使用该负压伤口治疗设备时不易受到带有异味气体的困扰和侵害,从而给使用者和患者带来方便。 Patients and staff in the use of the negative pressure wound therapy device and less susceptible to abuse problems with the smell of gas, so as to bring convenience to the user and the patient. 该负压伤口治疗设备也就具有消除异味,使用方便的优点。 The apparatus also has a negative pressure wound therapy to eliminate odor, easy to use for.

[0032]本发明的另一个实施例提供一种负压伤口治疗设备的气体净化方法。 Embodiment provides a negative pressure wound therapy device to another gas purification method [0032] embodiment of the present invention. 负压伤口治疗设备的气体净化方法可以对负压伤口治疗设备工作过程中产生的气体进行净化。 Negative pressure wound therapy device may be a gas purification method for purifying a gas negative pressure wound therapy device generated during operation. 其包括如下步骤: Comprising the steps of:
