技术领域Technical Field
本发明涉及引流装置技术领域，尤其涉及一种胸腔积液引流装置。The present invention relates to the technical field of drainage devices, and in particular to a pleural effusion drainage device.
背景技术Background technique
目前胸腔积液引流是胸腔积液处理的有效措施，其中，常用的引流装置为引流瓶式的负压引流装置，其在引流瓶上安装有引流管和抽气管，引流管连接一针筒，针筒上设置与针筒内部连通的空心钢针，使用时空心钢针刺入人体至积液位置，抽气管连接气泵给引流瓶抽气产生负压，从而将积液导出。At present, pleural effusion drainage is an effective measure for the treatment of pleural effusion. Among them, the commonly used drainage device is a drainage bottle-type negative pressure drainage device, in which a drainage tube and a suction tube are installed on the drainage bottle. The drainage tube is connected to a syringe, and a hollow steel needle connected to the inside of the syringe is arranged on the syringe. When in use, the hollow steel needle is inserted into the human body to the location of the effusion, and the suction tube is connected to an air pump to evacuate the drainage bottle to generate negative pressure, thereby draining the effusion.
在实际使用时，胸腔内部积液有时存在积液粘稠状况，导致积液导出不流畅，此时需要专门用注射器或其它装置向积液处注射一部分药液以减少积液的粘稠度，便于引流；这种方式需要至少两种装置完成作业，并且分别刺入人体至积液位置，增加了患者的痛苦。是否能够设计出一种可一次性刺入人体即可完成加药和引流作业的装置，人们一直在研究。In actual use, the effusion in the pleural cavity is sometimes viscous, which makes it difficult to drain the effusion. At this time, a syringe or other device is needed to inject a portion of the liquid medicine into the effusion to reduce the viscosity of the effusion and facilitate drainage. This method requires at least two devices to complete the operation, and they are inserted into the human body to the location of the effusion respectively, which increases the pain of the patient. Whether it is possible to design a device that can complete the drug addition and drainage operations by inserting it into the human body at one time has been studied.

具体实施方式Detailed ways
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
实施例，参照图1-图4，本实施例为一种胸腔积液引流装置，包括引流瓶1，所述引流瓶上安装有引流管2和抽气管3，所述抽气管的一端与所述引流瓶的内部连通，另一端位于引流瓶外，所述引流管的一端与所述引流瓶内部连通，另一端连接有导流装置，所述导流装置包括针筒4和推杆6，所述针筒的一端安装有与针筒内部连通的空心钢针5，所述推杆的一端固定有胶塞7，所述胶塞位于所述针筒内并且与所述针筒滑动连接；所述胶塞上设置有第一中心孔8和周向设置有位于第一中心孔外侧的侧孔9，所述胶塞靠近空心钢针的一侧设置有弹性片10，本实施例中，弹性片可以为橡胶片或硅胶片，所述弹性片遮挡住所述第一中心孔和侧孔，所述弹性片上周向设置有多个豁口11，相邻的豁口之间形成连接部12，所述连接部未与所述弹性片连接的一端与所述胶塞连接，使得所述弹性片抵在所述胶塞上；所述推杆上设置有与所述第一中心孔连通的第二中心孔13，所述引流管的另一端与所述第二中心孔连通；所述针筒上远离空心钢针的一端设置挡板14，所述推杆的另一端穿过所述挡板与引流管连接，所述挡板与所述推杆之间有间距，所述挡板上对应所述侧孔的位置设置有能够插入所述侧孔的支撑杆15，所述支撑杆的长度大于所述侧孔的长度。Embodiment, referring to Figures 1 to 4, this embodiment is a pleural effusion drainage device, including a drainage bottle 1, on which a drainage tube 2 and an exhaust tube 3 are installed, one end of the exhaust tube is connected to the interior of the drainage bottle, and the other end is located outside the drainage bottle, one end of the drainage tube is connected to the interior of the drainage bottle, and the other end is connected to a diversion device, the diversion device includes a syringe 4 and a push rod 6, one end of the syringe is equipped with a hollow steel needle 5 connected to the interior of the syringe, one end of the push rod is fixed with a rubber plug 7, the rubber plug is located in the syringe and is slidably connected to the syringe; the rubber plug is provided with a first central hole 8 and circumferentially provided with side holes 9 located outside the first central hole, and an elastic sheet 10 is provided on the side of the rubber plug close to the hollow steel needle. In this embodiment, the elastic sheet It can be a rubber sheet or a silicone sheet, the elastic sheet covers the first center hole and the side holes, the elastic sheet is circumferentially provided with a plurality of notches 11, a connecting portion 12 is formed between adjacent notches, the end of the connecting portion not connected to the elastic sheet is connected to the rubber plug, so that the elastic sheet rests on the rubber plug; the push rod is provided with a second center hole 13 connected to the first center hole, and the other end of the drainage tube is connected to the second center hole; a baffle 14 is provided on the end of the syringe away from the hollow steel needle, the other end of the push rod passes through the baffle and is connected to the drainage tube, there is a spacing between the baffle and the push rod, and a support rod 15 that can be inserted into the side hole is provided at a position on the baffle corresponding to the side hole, and the length of the support rod is greater than the length of the side hole.
上述的胸腔积液引流装置在使用时，如果患者胸腔积液存在粘稠状况，可拉动推杆抽取部分药液然后推动推杆注射至胸腔积液处使得胸腔积液粘稠度降低，然后拉动推杆直至支撑柱插入侧孔内将弹性片顶起，此时豁口位置与第一中心孔连通，抽气管位于引流瓶以外的一端预先连接气泵，打开气泵即可使得引流瓶内产生负压，积液在负压的作用下依次经过空心钢针-豁口-第一中心孔-第二中心孔-引流管到达引流瓶，完成引流作业；由此可见，该引流装置空心钢针一次性刺入人体即可完成加药和引流作业。When the above-mentioned pleural effusion drainage device is in use, if the patient's pleural effusion is viscous, the push rod can be pulled to extract part of the medicine liquid and then pushed to inject it into the pleural effusion to reduce the viscosity of the pleural effusion. Then, the push rod is pulled until the support column is inserted into the side hole to lift the elastic sheet. At this time, the notch position is connected to the first center hole, and the end of the suction tube outside the drainage bottle is pre-connected with the air pump. Turning on the air pump can generate negative pressure in the drainage bottle. Under the action of negative pressure, the effusion passes through the hollow steel needle-notch-first center hole-second center hole-drainage tube in sequence to reach the drainage bottle, completing the drainage operation. It can be seen that the hollow steel needle of the drainage device can complete the medication and drainage operations by piercing the human body once.
作为一种较佳的实施方式，参见图5-图7，所述推杆上设置有防滑齿16，所述挡板的内侧面设置有多个用于容纳防滑齿的防滑槽17。其中，所述防滑齿至所述胶塞的距离优选小于等于所述支撑杆的长度。本实施例中，所述防滑齿优选倾斜设置，靠近胶塞的一面与推杆之间的夹角小于90°。所述防滑齿可以为一个，也可以为多个，所述防滑槽的数量大于防滑齿的数量。这样，在拉动推杆时，当支撑杆穿过侧孔后将弹性片顶开时，防滑齿可依次进入防滑槽内，防止推杆反向运动导致第一中心孔再次堵塞；该结构也有效防止不法分子回收重复使用的情况发生，避免因此造成的患者交叉感染的风险；此外，防滑齿进入不同的防滑槽内可使得支撑杆传过侧孔的长度不同，进而使得豁口变形大小不同，以便于分级调节引流速度，以适应患者的身体状况。As a preferred embodiment, referring to Fig. 5-Fig. 7, the push rod is provided with anti-skid teeth 16, and the inner side surface of the baffle is provided with a plurality of anti-skid grooves 17 for accommodating the anti-skid teeth. The distance from the anti-skid teeth to the rubber plug is preferably less than or equal to the length of the support rod. In this embodiment, the anti-skid teeth are preferably arranged obliquely, and the angle between the side close to the rubber plug and the push rod is less than 90°. The anti-skid teeth can be one or more, and the number of the anti-skid grooves is greater than the number of the anti-skid teeth. In this way, when the push rod is pulled, when the support rod passes through the side hole and pushes the elastic sheet open, the anti-skid teeth can enter the anti-skid grooves in turn to prevent the push rod from moving in the opposite direction and causing the first center hole to be blocked again; this structure also effectively prevents the occurrence of illegal elements recycling and reusing, avoiding the risk of cross infection of patients caused by this; in addition, the anti-skid teeth entering different anti-skid grooves can make the support rod pass through the side hole at different lengths, thereby making the notch deformation size different, so as to facilitate graded adjustment of the drainage speed to adapt to the patient's physical condition.
作为一种较佳的实施方式，所述引流管与所述推杆可拆卸连接；也可以将所述引流管与所述引流瓶设置为可拆卸连接，一般的可使用插接的方式，这样可方便的将针筒和推杆部分分离，一是可以将引流瓶清洁后再次使用，节约资源，二是对于积液较少且非粘稠状态时，针筒和推杆部分可直接抽取积液，使用更方便。当然在液较少且非粘稠状态时，该引流装置也可以直接使用，省去抽取和注射药液的步骤即可。As a preferred embodiment, the drainage tube is detachably connected to the push rod; the drainage tube and the drainage bottle can also be detachably connected, generally in a plug-in manner, so that the syringe and the push rod can be easily separated. First, the drainage bottle can be cleaned and reused to save resources. Second, when the effusion is less and non-viscous, the syringe and the push rod can directly extract the effusion, which is more convenient to use. Of course, when the fluid is less and non-viscous, the drainage device can also be used directly, eliminating the steps of extracting and injecting the liquid medicine.
需要说明的是，上述实施例仅仅是对本申请的举例说明，不是对本申请的限制，比如导流装置使用其它导流装置，第一中心孔的开闭也可以使用其它结构控制，只要能实现本发明的目的即可。It should be noted that the above embodiments are merely examples of the present application and not limitations of the present application. For example, the guide device may use other guide devices and the opening and closing of the first center hole may also be controlled by other structures as long as the purpose of the present invention can be achieved.
以上所述仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
