本实用新型属于医疗设备领域，具体地说，涉及一种内置冲洗滴注管的封闭创面敷料装置。The utility model belongs to the field of medical equipment, in particular to a closed wound dressing device with a built-in flushing drip tube.
背景技术Background technique
负压创面治疗(NegativePressureWoundTherapy，NPWT)是近些年来治疗复杂性创面的一个革命性进展。1992年，德国医学博士Fleischmann首创将创面封闭与传统负压引流结合促进创面愈合的方法。这种方法很快被广泛应用于体表各种急性或慢性伤口以及溃疡、大面积软组织缺损、战创伤所致组织缺损或脏器外露等情况下创面的覆盖及引流；此外，该方法还可以应用于各种感染性软组织损伤的治疗。Negative Pressure Wound Therapy (NPWT) is a revolutionary progress in the treatment of complex wounds in recent years. In 1992, German medical doctor Fleischmann pioneered the method of combining wound sealing with traditional negative pressure drainage to promote wound healing. This method was soon widely used in the coverage and drainage of various acute or chronic wounds on the body surface, ulcers, large soft tissue defects, tissue defects caused by war trauma, or exposed organs; in addition, this method can also Applied to the treatment of various infected soft tissue injuries.
在应用NPWT技术的过程中，开孔敷料是最为重要的部分。敷料填塞并直接覆盖创面组织，用于保持创面湿润，为创面愈合制造适宜的局部环境。在负压吸引下水肿及渗出物经敷料微孔被引流。负压产生的抽吸作用转变为敷料对组织表面的压力，可使部分创面组织陷入敷料孔隙中，从而使创面组织产生微形变和与界面间的应力，引起组织张力发生变化，激活力传导通路，从而促进细胞的增殖和分化，加快新生肉芽组织的形成。因此，敷料是影响NPWT治疗效果的关键因素。The open-pore dressing is the most important part in the application of the NPWT technique. The dressing packs and directly covers the wound tissue to keep the wound moist and create a suitable local environment for wound healing. Edema and exudate are drained through the micropores of the dressing under negative pressure suction. The suction effect generated by the negative pressure is transformed into the pressure of the dressing on the tissue surface, which can cause part of the wound tissue to sink into the pores of the dressing, thereby causing micro-deformation of the wound tissue and stress between the wound tissue and the interface, causing changes in tissue tension and activating force conduction pathways , thereby promoting cell proliferation and differentiation, and accelerating the formation of new granulation tissue. Therefore, the dressing is a key factor affecting the therapeutic effect of NPWT.
目前在使用敷料进行治疗的过程中，敷料材料自身的理化特性和结构弊端逐渐显露。有研究人员发现敷料微孔易堵塞，一旦堵塞就会导致负压治疗失效，且会加重污染创面的感染。另一些研究人员对敷料的细菌数量进行定量研究发现：97％的敷料中可发现1种以上的细菌，54％的敷料中有2种以上细菌，在NPWT治疗时敷料中细菌数量维持在104CFU/ml～106CFU/ml的高水平，常规的更换敷料并不能有效减少细菌数量。At present, in the process of using dressings for treatment, the physical and chemical properties and structural disadvantages of dressing materials themselves are gradually revealed. Some researchers have found that the micropores of the dressing are easy to clog, and once clogged, the negative pressure therapy will fail and the infection of the polluted wound will be aggravated. Other researchers conducted quantitative studies on the number of bacteria in dressings and found that: 97% of the dressings had more than one type of bacteria, 54% of the dressings had more than two types of bacteria, and the number of bacteria in the dressing was maintained at 104 during NPWT treatment. With a high level of CFU/ml ~ 106 CFU/ml, routine dressing changes cannot effectively reduce the number of bacteria.
此外，不同孔径的敷料还会产生不同的问题：小孔敷料更容易堵塞，导致引流不畅；而大孔敷料则容易导致肉芽组织长入微孔内，在更换敷料时引起新鲜出血，给患者带来极大痛苦。In addition, dressings with different pore sizes will also cause different problems: dressings with small pores are more likely to be blocked, resulting in poor drainage; while dressings with large pores are likely to cause granulation tissue to grow into the micropores, causing fresh bleeding when the dressing is changed, which is harmful to the patient. cause great pain.
综上，现有的封闭创面敷料装置，无法同时解决敷料微孔堵塞和肉芽组织生长至微孔内的问题；且无法实现将药液全方位送达敷料及创面，因此灌洗及冲洗的效果不佳，无法达到临床治疗的需要。To sum up, the existing closed wound dressing device cannot simultaneously solve the problems of dressing micropore blockage and granulation tissue growth into the micropore; and it is impossible to deliver the medicinal liquid to the dressing and wound in all directions, so the effect of lavage and flushing Poor, unable to meet the needs of clinical treatment.

This example is only an example and is not intended to limit the present invention. Before using the closed wound dressing device with a built-in flushing drip tube provided by the utility model, firstly carry out wound debridement, and it can be used when there is no fresh active bleeding on the wound surface. Cut the auxiliary material part 1 according to the external condition of the wound, and ensure that the main pipe 3 is located in the center of the dressing part 1 . Then the first dressing layer 4 is attached to the wound surface, and the second dressing layer 5 is located outside the wound surface. Afterwards, the external flushing drip tube 7 built in the negative pressure drainage tube 10 is connected to the main pipe 3 built in the second dressing layer 5 through the third connecting device 6 . After the connection is completed, the suction cup-shaped opening 9 and the second dressing layer are flatly attached; after the attachment, the suction cup-shaped opening 9, the second dressing layer 5 and the periwound tissue are closed with a medical semi-permeable film. Preferably, the medical semipermeable patch is a polyurethane semipermeable membrane. The far end of the negative pressure drainage tube 10 is connected to the drainage bottle and the negative pressure source through the second connecting device. Finally, adjust the negative pressure value of the instrument to start treatment, and the negative pressure value is preferably 75mmHg-125mmHg.
根据创面渗出情况，可在负压治疗同时对创面及敷料部分1进行冲洗，用注射器抽取冲洗液通过第一连接装置8注入外置冲洗滴注管7。冲洗液从外置冲洗滴注管7进入总管3，再从总管3流入多个内置冲洗滴注管2，经内置冲洗滴注管2的远端流出，均匀分布于敷料部分1及创面的外周边缘。在负压抽吸的作用下，冲洗液由外周向中心流动，同时冲洗敷料部分1及创面，最终通过负压引流管10排出。需要向创面滴注药液时，可将仪器负压值调低，外置冲洗滴注管7可通过第一连接装置8与输液器相连，滴注给药。According to the exudation of the wound surface, the wound surface and the dressing part 1 can be flushed during the negative pressure treatment, and the flushing liquid is extracted with a syringe and injected into the external flushing drip tube 7 through the first connecting device 8 . The rinsing liquid enters the main pipe 3 from the external rinsing drip tube 7, then flows into multiple built-in rinsing drip tubes 2 from the main tube 3, flows out through the distal end of the built-in rinsing drip tube 2, and is evenly distributed on the dressing part 1 and the periphery of the wound surface edge. Under the effect of negative pressure suction, the flushing liquid flows from the outer circumference to the center, flushes the dressing part 1 and the wound surface at the same time, and is finally discharged through the negative pressure drainage tube 10 . When it is necessary to instill medicinal solution to the wound surface, the negative pressure value of the instrument can be lowered, and the external flushing infusion tube 7 can be connected with the infusion set through the first connection device 8 for infusion administration.
优选的，所述第一连接装置8、第二连接装置11和/或第三连接装置6为可以使两根或多根医用滴管相连接的装置，例如接头。Preferably, the first connection device 8 , the second connection device 11 and/or the third connection device 6 are devices capable of connecting two or more medical droppers, such as joints.
