背景技术Background technique
各种吻合口瘘、胰瘘、胆瘘、肠瘘、结肠梗阻等是外科手术后常见的棘手问题，当发生上述问题时，需要通过引流进行治疗，例如当肠道的手术刀口处发生肠瘘时，肠液会从肠瘘处流出肠道，而肠液具有一定的腐蚀性，流出肠道后会对患者的其他组织器官造成损害，当流出肠道的肠液积累较多时甚至会危及生命，这时就需要通过引流的方法将肠液引流到患者体外。引流是普外科的基本治疗方法之一，有效的引流可以起到有效观察病情，促进机体愈合的作用，有时引流甚至是挽救生命的主要措施。Various anastomotic leakage, pancreatic fistula, biliary fistula, intestinal fistula, colonic obstruction, etc. are common difficult problems after surgery. When the above problems occur, drainage should be used for treatment. For example, when intestinal fistula occurs at the surgical incision of the intestinal tract Intestinal fluid will flow out of the intestinal tract from the fistula, and the intestinal fluid is corrosive to a certain extent, and it will cause damage to other tissues and organs of the patient after flowing out of the intestinal tract. It is necessary to drain the intestinal fluid out of the patient's body by drainage. Drainage is one of the basic treatment methods in general surgery. Effective drainage can effectively observe the condition and promote the healing of the body. Sometimes drainage is even the main measure to save lives.

Place the drain in the patient. However, for patients who need long-term abdominal drainage, the current drainage methods are not effective, and the main performance is poor drainage. The reason is that the drainage tube is easily blocked by necrosis, pus, intestinal contents or soft tissues of the human body. Replace the drainage tube, and when replacing the drainage tube, because the operation has ended, it is difficult to place the drainage tube in the correct position in the patient's body, which greatly affects the drainage effect and therapeutic effect.

下面结合图1介绍本实用新型引流管的使用方法，第一步，在手术过程中，将第一外管10的Q端放入患者体内手术刀口附近的位置，并将第一外管10的另一端即P端置于患者体外；第二步，当医生发现需要进行引流时，将内管12伸入第一外管10中，再将第一外管10的P端插入第二外管11的N端，使第一外管10与第二外管11固定连接；第三步，将第二外管11远离第一外管10的一端即M端与真空泵16连接，再向内管12中注入冲洗液，该冲洗液通过内管12流入患者体内进行冲洗，其中内管12伸入第一外管10中并位于第一外管10的Q端附近能够使冲洗液对患者的冲洗效果更好；真空泵16的作用是产生负压，对患者体内的冲洗液产生向外的吸引力，患者体内的冲洗液在真空泵16产生的吸引力作用下，顺着第一外管10和第二外管11流入真空泵16中。Below in conjunction with Fig. 1 introduce the using method of the drainage tube of the present utility model, the first step, in the operation process, put the Q end of the first outer tube 10 into the position near the surgical incision in the patient's body, and place the Q end of the first outer tube 10 The other end, the P end, is placed outside the body of the patient; in the second step, when the doctor finds that drainage is needed, the inner tube 12 is inserted into the first outer tube 10, and then the P end of the first outer tube 10 is inserted into the second outer tube 11, the first outer tube 10 is fixedly connected to the second outer tube 11; the third step is to connect the end of the second outer tube 11 away from the first outer tube 10, that is, the M end, to the vacuum pump 16, and then to the inner tube 12 to inject irrigation fluid, which flows into the patient's body through the inner tube 12 for irrigation, wherein the inner tube 12 extends into the first outer tube 10 and is located near the Q end of the first outer tube 10 to enable the irrigation fluid to flush the patient The effect is better; the function of the vacuum pump 16 is to generate negative pressure to generate an outward attraction to the flushing fluid in the patient's body, and the flushing fluid in the patient's body will flow along the first outer tube 10 and the second The two outer tubes 11 flow into the vacuum pump 16 .
其中，压力调节孔13的作用是调节压力，当第二外管11上没有设置压力调节孔13时，真空泵16产生的对患者体内的冲洗液的吸引力会容易对患者体内人体的软组织产生吸引，这样软组织很容易将第一外管10的Q端封堵导致堵塞，无法进行引流，而在第二外管11上设置压力调节孔13后，一部分空气通过压力调节孔13进入第一外管10和第二外管11内，进而调节第一外管10和第二外管11内的压力，从而避免了软组织堵塞第一外管10的情况的发生，使引流通畅，在引流过程中，压力调节孔13一直处于敞开状态，而当患者下床活动时，可以将压力调节孔盖14插入压力调节孔13中，以防止冲洗液从压力调节孔13泄漏。保护罩15罩于压力调节孔13上方，能够对压力调节孔13形成保护，以防止患者身体压住或者患者的被子压住压力调节孔13而堵住压力调节孔13，保证引流通畅。本实用新型引流管的第一外管10和第二外管11为分体式设计，在治疗过程中更换引流管时，只需要更换第二外管11，不用更换第一外管10，避免了更换引流管时难以将引流管放置到患者体内正确的位置的情况，从而提高了引流效果和治疗效果，同时也减轻了患者的痛苦。Wherein, the function of the pressure regulating hole 13 is to regulate the pressure. When the second outer tube 11 is not provided with the pressure regulating hole 13, the suction force generated by the vacuum pump 16 to the flushing fluid in the patient's body will easily attract the soft tissue of the patient's body. In this way, the soft tissue can easily block the Q end of the first outer tube 10 to cause blockage, and drainage cannot be performed. After the pressure adjustment hole 13 is set on the second outer tube 11, a part of the air enters the first outer tube through the pressure adjustment hole 13 10 and the second outer tube 11, and then adjust the pressure in the first outer tube 10 and the second outer tube 11, thereby avoiding the occurrence of soft tissue blocking the first outer tube 10, so that the drainage is smooth. During the drainage process, The pressure regulating hole 13 is always in an open state, and when the patient gets out of bed, the pressure regulating hole cover 14 can be inserted into the pressure regulating hole 13 to prevent the flushing fluid from leaking from the pressure regulating hole 13 . Protective cover 15 covers pressure regulating hole 13 top, can form protection to pressure regulating hole 13, to prevent patient's body from pressing down or patient's quilt from pressing pressure regulating hole 13 and blocking pressure regulating hole 13, guarantees smooth drainage. The first outer tube 10 and the second outer tube 11 of the drainage tube of the present utility model are of a split design. When replacing the drainage tube during treatment, only the second outer tube 11 needs to be replaced instead of the first outer tube 10, which avoids When replacing the drainage tube, it is difficult to place the drainage tube in the correct position in the patient's body, thereby improving the drainage effect and treatment effect, and also reducing the pain of the patient.

如图2和图3所示，本实施例的引流管与实施例一的引流管的区别是压力调节孔13上连接有调节筒19，该调节筒19为管状结构，该调节筒19的内壁设有螺纹，该调节筒19中安装有调节螺栓20，该调节螺栓20的螺杆22上设有全螺纹，且螺杆22上沿调节螺栓20的轴向设有若干个调节槽21，例如本实施例中螺杆22上设有三个调节槽21，该调节槽21为楔形，即该调节槽21靠近调节螺栓20的头部23的一端的深度小于该调节槽21远离头部23的一端的深度，该深度是指调节槽21沿螺杆22径向的深度。本实施例中第二外管上未设置压力调节孔盖。As shown in Figures 2 and 3, the difference between the drainage tube of this embodiment and the drainage tube of Embodiment 1 is that the pressure regulating hole 13 is connected with a regulating cylinder 19, the regulating cylinder 19 is a tubular structure, and the inner wall of the regulating cylinder 19 Threads are provided, and an adjusting bolt 20 is installed in the adjusting cylinder 19. The screw 22 of the adjusting bolt 20 is provided with a full thread, and the screw 22 is provided with several adjusting grooves 21 along the axial direction of the adjusting bolt 20, such as in this embodiment In the example, the screw rod 22 is provided with three adjustment grooves 21, and the adjustment grooves 21 are wedge-shaped, that is, the depth of the adjustment groove 21 near the head 23 of the adjustment bolt 20 is smaller than the depth of the adjustment groove 21 away from the end of the head 23. The depth refers to the depth of the adjustment groove 21 along the radial direction of the screw rod 22 . In this embodiment, no pressure regulating hole cover is provided on the second outer tube.
本实施例中在调节孔13上连接调节筒19和调节螺栓20，目的是为了调节通过调节孔13流入或流出第二外管11的空气流量，具体的操作方法为：将调节螺栓20安装于调节筒19中，然后向上旋拧调节螺栓20，当调节槽21从调节筒19露出后，空气经调节槽21流入或流出第二外管11，由于调节槽21为楔形，所以越向上旋拧调节螺栓20，通过调节槽21的空气流量就越大，然后可以将调节螺栓20向下旋拧，越向下旋拧调节螺栓20，通过调节槽21的空气流量就越小，当调节槽21全部位于调节筒19中时，调节螺栓20将调节孔13封堵。In this embodiment, the adjustment cylinder 19 and the adjustment bolt 20 are connected on the adjustment hole 13, the purpose is to adjust the flow of air flowing into or out of the second outer tube 11 through the adjustment hole 13, the specific operation method is: install the adjustment bolt 20 on In the adjustment cylinder 19, turn the adjustment bolt 20 upwards. When the adjustment groove 21 is exposed from the adjustment cylinder 19, the air flows into or out of the second outer tube 11 through the adjustment groove 21. Since the adjustment groove 21 is wedge-shaped, the more upward the screw is, Adjust the bolt 20, the greater the air flow through the adjustment slot 21, then the adjustment bolt 20 can be screwed down, the more the adjustment bolt 20 is screwed down, the smaller the air flow through the adjustment slot 21, when the adjustment slot 21 When all are located in the adjusting cylinder 19, the adjusting bolt 20 will block the adjusting hole 13.
