本发明涉及医疗器械领域，特别涉及一种Y型连接阀。The invention relates to the field of medical instruments, in particular to a Y-type connecting valve.
背景技术Background technique
在现有血管介入治疗中，需要对血管进行穿刺，并利用器械建立进入人体的管路。通常是将导管鞘穿刺血管，并插入血管内，然后将导引导管的延导管鞘朝血管内导入。在导引导管的基端安装Y型连接阀，以搭建连接导引导管和导入构建的通道，从而防止血液从导入构件和导引导管的间隙渗出。Y型连接阀主要由Y型的主体、鲁尔接头和密封圈构成。鲁尔接头用以与导引导管连接，密封圈用以与导入构件贴合密封；In the existing vascular interventional therapy, it is necessary to puncture the blood vessel, and use instruments to establish a pipeline into the human body. Usually, the catheter sheath is punctured into the blood vessel and inserted into the blood vessel, and then the catheter sheath along the guide catheter is introduced into the blood vessel. A Y-shaped connection valve is installed at the base end of the guide catheter to build a channel connecting the guide catheter and the introduction structure, thereby preventing blood from leaking out from the gap between the introduction member and the guide catheter. The Y-type connection valve is mainly composed of a Y-type body, a Luer connector and a sealing ring. The luer connector is used to connect with the guide tube, and the sealing ring is used to fit and seal with the introduction member;
目前市场上Y型连接阀根据密封圈的打开关闭方式分类，主要有两种形式：按压式和旋转式。按压式的密封圈初始为封闭状态，使用前按下密封圈盖，打开形成通道供导入构件穿过，再及时拔开密封圈盖，防止血液渗出，但是由于按压式密封的原理借助密封圈自身弹性与导入构件的表面贴合，一般贴合力较小，因此按压式Y型连接阀在进行动力注射时所能承受的最大注射压力不高。旋转式的密封圈初始为打开状态，可直接穿入导入构件，然后再旋紧密封圈盖，形成密封；旋转式的密封原理是通过外力挤压密封圈，从而缩小密封圈内腔，压迫密封圈与导入构件贴合，因此能够承受的注射压力更大，但是由于密封圈初始为打开状态，术中容易产生血液漏出，因此需要设计一种能够防止倒入构件在插入时出现的血液露出的情况的Y型连接阀。At present, the Y-type connection valve on the market is classified according to the opening and closing method of the sealing ring, and there are mainly two forms: push type and rotary type. The press-type sealing ring is initially closed. Before use, press the sealing ring cover to open the formed channel for the introduction member to pass through, and then pull out the sealing ring cover in time to prevent blood leakage. However, due to the principle of the press-type sealing, the sealing ring is used The self-elasticity adheres to the surface of the introduction member, and the adhesion force is generally small, so the maximum injection pressure that the push-type Y-type connecting valve can withstand during power injection is not high. The rotary sealing ring is initially open and can be directly penetrated into the introduction member, and then the sealing ring cover is tightened to form a seal; the principle of rotary sealing is to squeeze the sealing ring through external force, thereby reducing the inner cavity of the sealing ring and pressing the seal The ring is fitted with the introduction member, so it can withstand higher injection pressure. However, since the sealing ring is initially open, blood is likely to leak during the operation, so it is necessary to design a device that can prevent the blood from being exposed when the pouring member is inserted. case of the Y-connection valve.

具体实施方式Detailed ways
下面结合附图，对本发明的一个具体实施方式进行详细描述，但应当理解本发明的保护范围并不受具体实施方式的限制。A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.
实施例一Example 1
如图1和图2所示，本发明实施例提供的一种Y型连接阀，包括1、一种Y型连接阀，其特征在于，包括：As shown in FIG. 1 and FIG. 2 , a Y-type connection valve provided by an embodiment of the present invention includes 1. A Y-type connection valve, which is characterized in that it includes:
阀体1，其包括主管以及与所述主管连通的支管；A
鲁尔接头2，其套接在所述主管的一端上；
密封圈盖3，其螺纹连接与所述主管的另一端上；A sealing
O型圈4，其垫在所述鲁尔接头2与所述阀体1之间；以及O-
密封圈5，其置于所述主管一端开设的空腔内，所述密封圈5内设置有一与导入构件过盈配合的密封件；A
所述密封圈盖3的一部分伸入所述空腔内并抵触在所述密封圈5的端部，转动所述密封圈盖3能够使得所述密封圈产生向内挤压的压缩形变；A part of the sealing
所述主管上设置有外螺纹，所述密封圈盖3上设置有与所述外螺纹配合的内螺纹；The main pipe is provided with an external thread, and the
为起到防滑效果，进一步的，所述密封圈盖3外表面上设置有防滑纹In order to play the anti-skid effect, further, the outer surface of the
所述鲁尔接头2通过卡扣结构固定在所述阀体2上；The
密封件与导入构件过盈配合，较之现有的Y型止血阀需要拧动密封圈盖3才能够密封的方式，在导入构件插入时，能够有效防止血液喷出。The sealing element and the introduction member are in interference fit. Compared with the existing Y-shaped hemostatic valve, the sealing
实施例二
在实施例一的基础上，如图3-图5所示，所述密封件为设置在所述密封圈5内的密封耳板6，所述密封耳板6的厚度为所述密封圈5的厚度的五分之一，密封耳板6的厚度影响导入构件插入的阻力，因此将其设置为密封圈5厚度的五分之一，若密封耳板6过厚会导致导入构件插入阻力过大，过薄会导致初封效果差；On the basis of
当导入构件插入密封圈5内时，如图4所示，会使得密封耳板6发生形变，密封耳板6在发生形变时，也会拉动密封圈5发生形变，即让密封圈5靠近密封圈盖3的一端向内变形，如图5所示，所述密封圈盖3伸入所述空腔内的端部形状为喇叭状，此时拧动密封圈盖3便于将密封圈5向内挤压，达到将导入构件完全固定、密封的效果。When the introduction member is inserted into the sealing
工作原理：在介入手术中，预先将Y型连接阀侧边接头封堵，然后将Y型连接阀的鲁尔接头2与导引导管的连接座旋紧，再将导入构件从Y型连接阀密封圈盖3的尾部中间腔道穿入，此时密封圈5内的密封内耳6与导入构件贴合，可以形成初封，防止血液直接喷出，再将密封圈盖3拧紧，此时密封圈盖逐渐旋进Y型阀体，挤压密封圈5，密封圈5内径缩小，将导入构件锁紧。待手术结束后，旋松密封圈盖3，取出导入构件。Working principle: In interventional surgery, the side joint of the Y-type connecting valve is blocked in advance, then the
实施例三
在实施例一的基础上，如图6和图7所示，所述密封件为设置在所述密封圈5远离所述密封圈盖3的一侧的密封环7，所述密封环7为螺旋形状，所述空腔内壁上设置有螺旋形状的凸台11，所述凸台11与所述密封环7之间相互交错；On the basis of
所述密封环7中心处的密封路径的直径小于所述密封圈5内孔的直径。The diameter of the sealing path at the center of the sealing
所述密封圈5与所述密封环7为一体化结构，通过3D打印技术生产，密封圈5内设置有一台阶孔结构12，以便于密封圈5的内孔与密封环7的密封路径间的过渡；The sealing
导入构件插入密封环7内时，会带动密封环7移动，将密封环7挤在凸台11上，从而使得密封环7向内压缩，减少密封环7与导入构件之间的缝隙，提高密封效果；When the introduction member is inserted into the sealing
导入构件依次穿过密封圈5和密封环7，密封圈5的台阶孔结构12以及密封环7的密封路径均与导入构件过盈配合，在导入构件插入时，也有效起到防止血液喷出的作用，进一步的，当血液流动至螺旋形状的密封环7时，密封环7与空腔内壁构成的螺旋形状通道来减缓血液的流速，防止血液压力过大而导致初封效果差的情况发生，另外螺纹形状的密封环7也能够起到类似于弹簧的缓冲作用。The introduction member passes through the sealing
实施例四
在实施例一的基础上，如图8和图9所示，所述密封件包括设置在所述密封圈5内的两个密封板8以及连接两个所述密封板8的连接套9，两个所述密封板8上均开设有密封通道10，两个所述密封通道10的中心线以及所述密封圈5内孔的中心线均不重合，所述连接套9用于连通两个所述密封通道10；On the basis of
由于两个密封通道10的中心线以及密封圈5内孔的中心线均不重合，因此当导入构件插入其内时，两个密封板8对导入构件产生一横向剪切力，使得密封板8上的密封通道10与导入构件紧密贴合，达到防止血液露出的目的，由于两个密封通道10的中心线不重合，因此设计一连接套9来起到导向作用，防止导入构件直接将密封板8插坏，密封板8、密封套9以及密封圈5均为弹性橡胶件，具有良好的延展性。Since the centerlines of the two sealing
进一步的，所述密封通道为圆孔形状或十字形状，圆孔形状更容易贴合导入构件的表面，十字形状能够防止导入构件直接将密封板8顶裂，具体可根据实际情况选择。Further, the sealing channel is in the shape of a round hole or a cross. The shape of the round hole is easier to fit the surface of the introduction member, and the cross shape can prevent the introduction member from directly cracking the sealing
