Abstract

Disclosed is a fish eye valve (100), comprising a fish eye outer ring (101), a protruding fish eye portion (102) integrally formed with the fish eye outer ring (101), and a through hole (103) configured at a central position of the fish eye portion (102) for a puncture needle rod to pass therethrough. The fish eye portion (102) comprises a first thin-walled portion (1021) connected to the fish eye outer ring (101), a thick-walled portion (1022) connected to the first thin-walled portion (1021), and a second thin-walled portion (1023) connected to the thick-walled portion (1022). The wall thickness of both the first thin-walled portion (1021) and the second thin-walled portion (1023) is less than that of the thick-walled portion (1022). The through hole (103) is formed in the second thin-walled portion (1023). The hole wall at the hole opening of the through hole (103) farthest from the fish eye outer ring (101) bends from the inner side of the through hole (103) toward the outer side of the through hole (103) all along the circumference of the through hole (103), thus forming an arc-shaped rim (1031). A fit between the fish eye valve (100) and a matching puncture sealing assembly and puncture device with respect to the puncture needle rod ensures effective gas tightness while reducing a holding force of the puncture sealing assembly on the puncture needle rod, thus improving flexibility and smoothness in manipulating the puncture needle rod.

为了使本发明的内容更容易被清楚地理解,下面根据具体实施例并结合附图,对本发明作进一步详细的说明。In order to make the content of the present invention easier to understand clearly, the following further describes the present invention in detail based on specific embodiments and in conjunction with the accompanying drawings.
实施例1:Example 1:
请参阅图7所示,本实施例提供了一种适用于穿刺密封组件的鱼眼阀,包括:鱼眼外环101、以及与鱼眼外环101一体成型的凸起的鱼眼部102,以及在鱼眼部102的中心位置开设有适于穿刺针杆穿过的通孔103。其中鱼眼部102包括与鱼眼外环101相连的第一薄壁部1021、与第一薄壁部1021相连的厚壁部1022,以及与厚壁部1022相连的第二薄壁部1023;如此来说,使得整体的鱼眼部102的壁厚形成为从鱼眼外环101向通孔103方向为“薄厚薄”的结构。Referring to FIG. 7, this embodiment provides a fish-eye valve suitable for piercing a sealing assembly, including: a fish-eye outer ring 101 and a convex fish-eye portion 102 integrally formed with the fish-eye outer ring 101, And a through hole 103 suitable for the penetration of a puncture needle is opened at the center of the fisheye 102. The fish-eye portion 102 includes a first thin-walled portion 1021 connected with the fish-eye outer ring 101, a thick-walled portion 1022 connected with the first thin-walled portion 1021, and a second thin-walled portion 1023 connected with the thick-walled portion 1022; In this way, the wall thickness of the overall fisheye portion 102 is formed to have a "thin thickness" structure in the direction from the fisheye outer ring 101 to the through hole 103.
具体来说,第一薄壁部1021和第二薄壁部1023的壁厚均小于厚壁部1022的壁厚;以及通孔103形成于第二薄壁部1023,也即通孔103设置在第二薄壁部1023上,通孔103远离鱼眼外环101的孔口处的孔壁沿着通孔103的周向由通孔103内侧朝通孔103外侧翻边形成有弧形翻边1031。对于此处的弧形翻边1031来说,弧形翻边1031的弧形开口朝向背离通孔103的轴线一侧,此外,本实施例来说,弧形翻边1031的沿着通孔103的轴线方向的高度为0.3~1.0mm。Specifically, the wall thickness of the first thin-walled portion 1021 and the second thin-walled portion 1023 are both smaller than the wall thickness of the thick-walled portion 1022; and the through hole 103 is formed in the second thin-walled portion 1023, that is, the through hole 103 is provided in On the second thin-walled portion 1023, the hole wall of the through hole 103 away from the orifice of the fisheye outer ring 101 along the circumferential direction of the through hole 103 is flanged from the inner side of the through hole 103 to the outer side of the through hole 103 to form an arc-shaped flanging 1031. For the arc-shaped flanging 1031 here, the arc-shaped opening of the arc-shaped flanging 1031 faces the side away from the axis of the through hole 103. In addition, in this embodiment, the arc-shaped flanging 1031 is along the through hole 103. The height in the axial direction is 0.3 to 1.0 mm.
一种可选的情况下,第一薄壁部1021与第二薄壁部1023的壁厚相等;以及。厚壁部1022的壁厚为第一薄壁部1021和第二薄壁部1023的壁厚的1.2~1.6倍。还一种可选的情况下,第一薄壁部1021与第二薄壁部1023的壁厚不相等;以及厚壁部1022的壁厚为第一薄壁部1021和第二薄壁部1023中壁厚较大者的1.2~1.6倍。也就是说,对于第一薄壁部1021和第二薄壁部1023的壁厚只要比厚壁部1022薄即满足本实施例的使用情况。In an optional case, the wall thicknesses of the first thin-walled portion 1021 and the second thin-walled portion 1023 are equal; and. The thickness of the thick portion 1022 is 1.2 to 1.6 times the thickness of the first thin portion 1021 and the second thin portion 1023. In another optional case, the wall thicknesses of the first thin-walled portion 1021 and the second thin-walled portion 1023 are not equal; and the wall thickness of the thick-walled portion 1022 is the first thin-walled portion 1021 and the second thin-walled portion 1023 The middle wall thickness is 1.2 to 1.6 times that of the larger one. In other words, as long as the wall thickness of the first thin-walled portion 1021 and the second thin-walled portion 1023 is thinner than the thick-walled portion 1022, the application conditions of this embodiment are satisfied.
对于本实施例的鱼眼阀100来说,整体的鱼眼部102的壁厚从鱼眼外环101向通孔103方向为“薄厚薄”的结构,这样的结构在通孔103处仍然可以有效保持与穿过穿刺器的例如穿刺针杆器械在配合处的气密性,又使得鱼眼部102的“薄厚薄”的结构的壁厚降低整体的鱼眼部102对于例如穿刺针杆形成的抱紧阻力。详细来说,鱼眼阀100在与穿刺针杆配合的状态下,随着穿刺针杆的活动,鱼眼阀100的鱼眼部102需要配合穿刺针杆产生随动性变形,对此处的随动性变形来说,当需要保证通孔103与穿刺针杆的良好气密性,通孔103处需要保持与穿刺针杆良好的配合抱紧效果,如此,只能通过鱼眼部102整体产生与穿刺针杆较好的随动效果,才能既不影响气密性又能提高穿刺针杆活动时的顺畅度,而此处想要实现鱼眼部102良好的随动性,对鱼眼部102的壁厚进行薄壁处理,使得鱼眼部102的壁厚变薄,这样就可以降低鱼眼部102随着穿刺针杆适应性变形时的阻力,但是,鱼眼阀100同时还需要保持一定的强度以防止随着穿刺针杆的活动而对鱼眼部102产生损伤进而出现鱼眼部102破损影响气密性的现象发生,故此,对于壁厚变薄的鱼眼部102来说还需要对鱼眼部102的一部分侧壁形成壁厚较厚的结构,如此,使得鱼眼部102上壁厚较厚的部分来有效保证整体的鱼眼部102除了具有良好的随动性能,还具有一定的刚性,不易被损坏。For the fisheye valve 100 of this embodiment, the overall fisheye 102 has a "thin thickness" structure from the fisheye outer ring 101 to the through hole 103. Such a structure can still be used at the through hole 103. Effectively maintain the air-tightness of the puncture needle device that passes through the puncture device, such as the puncture needle shaft, and reduce the wall thickness of the "thin thickness" structure of the fisheye portion 102. The overall fisheye portion 102 is suitable for, for example, the puncture needle shaft. The holding resistance. In detail, when the fisheye valve 100 is matched with the puncture needle shaft, with the movement of the puncture needle shaft, the fisheye portion 102 of the fisheye valve 100 needs to cooperate with the puncture needle shaft to produce follow-up deformation. In terms of follow-up deformation, when it is necessary to ensure good airtightness between the through hole 103 and the puncture needle shaft, the through hole 103 needs to maintain a good fit and tightness with the puncture needle shaft. In this way, it can only pass through the fisheye 102 as a whole It can produce a better follow-up effect with the puncture needle bar, so as not to affect the air tightness and improve the smoothness of the puncture needle bar when moving, and here we want to achieve good follow-up performance of the fisheye 102, which is good for the fisheye. The wall thickness of the part 102 is thin-walled, so that the wall thickness of the fish-eye part 102 becomes thinner, so that the resistance of the fish-eye part 102 when the puncture needle is deformed adaptively can be reduced. However, the fish-eye valve 100 also needs Maintain a certain strength to prevent damage to the fisheye 102 caused by the movement of the puncture needle, and damage to the fisheye 102 affects the air tightness. Therefore, for the fisheye 102 with a thinner wall thickness It is also necessary to form a thicker wall structure on a part of the side wall of the fisheye 102, so that the thicker wall of the fisheye 102 can effectively ensure that the overall fisheye 102 has good follow-up performance, It also has a certain degree of rigidity and is not easily damaged.
其次,在通孔103的孔口形成的弧形翻边1031来说,弧形翻边1031主要意义在于在穿刺针杆与通孔103背离鱼眼外环101的孔口边沿存有一定的间隙,穿刺针杆退出穿刺器时,从通孔103的内壁与穿刺针杆的接触面来说,与穿刺针杆接触的通孔103的内壁为光滑的壁面结构而不存在边沿接触,其中,内壁与穿刺针杆接触的通孔103部分的内径适于与穿刺针杆的外径配合,使得该部分的通孔103的内壁形成对于穿刺针杆的外侧壁周向的包紧,而通孔103背离鱼眼外环101的孔口边沿由于不接触穿刺针杆,这样通孔103背离鱼眼外环101的孔口边沿就不会形成对于穿刺针杆退出时的阻碍影响,进而使得穿刺针杆可以快捷退出包括鱼眼阀100在内的穿刺密封组件。Secondly, for the arc-shaped flanging 1031 formed by the orifice of the through hole 103, the main meaning of the arc-shaped flanging 1031 is that there is a certain gap between the puncture needle shaft and the through hole 103 away from the edge of the fisheye outer ring 101. When the puncture needle shaft exits the puncture, from the contact surface between the inner wall of the through hole 103 and the puncture needle shaft, the inner wall of the through hole 103 contacting the puncture needle shaft has a smooth wall structure without edge contact, where the inner wall The inner diameter of the part of the through hole 103 that is in contact with the puncture needle shaft is adapted to match the outer diameter of the puncture needle shaft, so that the inner wall of the through hole 103 of this part forms a circumferential tightness to the outer side wall of the puncture needle shaft, and the through hole 103 Since the edge of the orifice away from the fisheye outer ring 101 does not touch the puncture needle shaft, the through hole 103 away from the edge of the orifice of the fisheye outer ring 101 will not hinder the exit of the puncture needle shaft, thereby making the puncture needle shaft The piercing seal assembly including the fisheye valve 100 can be quickly withdrawn.

再详细来说,本实施例采用的S形连接部203包括与第一基台201相连的小U形折叠部2031,以及与第二基台202相连的大U形折叠部2032;其中小U形折叠部2031与大U形折叠部2032共有一侧壁;小U形折叠部2031凸起于第一基台201,大U形折叠部2032凸起于第二基台202,且小U形折叠部2031相对于第一基台201凸起的方向与大U形折叠部2032相对于第二基台202凸起的方向相反。对于本实施例的摆动膜200采用具有一定弹性的材质制成,例如但不限于医用高分子塑料或者橡胶或者硅胶,其中医用高分子塑料例如医用聚四氟乙烯,如此,通过材质的弹性配合S形连接部602203来共同实现摆动膜200随着穿刺针杆活动而呈现良好的随动性。In more detail, the S-shaped connecting portion 203 used in this embodiment includes a small U-shaped folding portion 2031 connected to the first base 201, and a large U-shaped folding portion 2032 connected to the second base 202; The U-shaped folded portion 2031 and the large U-shaped folded portion 2032 share a side wall; the small U-shaped folded portion 2031 protrudes from the first base 201, the large U-shaped folded portion 2032 protrudes from the second base 202, and has a small U-shaped The direction in which the folded portion 2031 protrudes relative to the first base 201 is opposite to the direction in which the large U-shaped folded portion 2032 protrudes relative to the second base 202. For the oscillating membrane 200 of this embodiment, it is made of a material with certain elasticity, such as but not limited to medical polymer plastic or rubber or silica gel. Among them, the medical polymer plastic is medical polytetrafluoroethylene. In this way, the material is elastically matched. The shaped connecting portion 602203 together realizes that the oscillating membrane 200 exhibits good followability with the movement of the puncture needle shaft.
在本实施例的摆动膜200具体运用在穿刺密封组件中时,第一基台201适于与穿刺密封组件的其它结构配接固定,第二基台202用于与穿刺器的套管盖1配接固定。此处对于小U形折叠部2031相对于第一基台201凸起的方向与大U形折叠部2032相对于第二基台202凸起的方向相反来说,一种可选的情况是,小U形折叠部2031相对于第一基台201为朝向穿刺器的套管盖1一侧凸起,而大U形折叠部2032相对于第一基台201为背离穿刺器的套管盖1一侧凸起;还一种可选的情况是小U形折叠部2031相对于第一基台201为背离穿刺器的套管盖1一侧凸起,而大U形折叠部2032相对于第一基台201为朝向穿刺器的套管盖1一侧凸起,本实施例附图以该种情况为,在这种情况下,此时,理论上上来讲,小U形折叠部2031和大U形折叠部2032形成的S形连接部203的扭曲变形性受到小U形折叠部2031相对于第一基台201凸起的高度和大U形折叠部2032相对于第二基台202凸起的高度的影响,即凸起的高度越大,S形连接部203的扭曲变形的空间越大。但是,由于背离穿刺器的套管盖1一侧也就是鱼眼阀100所在侧,鱼眼阀100主要形成在穿刺针杆活动过程中良好的随动性,又能兼顾良好的密封性,就需要与鱼眼阀100共同形成穿刺密封组件的包括摆动膜200具有良好的随动性,也就是说,由第一基台201背离穿刺器的套管盖1的一侧为鱼眼阀100带动整体的穿刺密封组件随着穿刺针杆活动的活动区间,此处,考虑到在有效保证S形连接部203的扭曲变形空间的前提下还需要兼顾考虑降低小U形折叠部2031相对于第一基台201凸起的过高对于鱼眼阀100带动整体的穿刺密封组件随着穿刺针杆活动的影响,本实施例设计的小U形折叠部2031相对于第一基台201凸起的高度小于大U形折叠部2032相对于第二基台202凸起的高度。即充分利用大U形折叠部2032朝向穿刺器的套管盖1一侧凸起的高度来为S形连接部203提供相对较大的扭曲变形空间,结合控制小U形折叠部2031相对于第一基台201的凸起高度在满足为S形连接部203提供扭曲变形空间的同时又降低对于鱼眼阀100带动穿刺密封组件整体形成相对于穿刺针杆随动时的影响。When the oscillating membrane 200 of this embodiment is specifically used in the puncture sealing assembly, the first abutment 201 is suitable for mating and fixing with other structures of the puncture sealing assembly, and the second abutment 202 is used to connect to the sleeve cover 1 of the puncture device. The mating is fixed. Here, for the convex direction of the small U-shaped folded portion 2031 relative to the first base 201 and the convex direction of the large U-shaped folded portion 2032 relative to the second base 202 are opposite, an optional situation is: The small U-shaped folded portion 2031 is convex toward the side of the cannula cover 1 of the trocar with respect to the first abutment 201, and the large U-shaped folded portion 2032 is the cannula cover 1 facing away from the trocar with respect to the first abutment 201. One side protruding; another optional situation is that the small U-shaped folded portion 2031 with respect to the first base 201 is convex on the side facing away from the sleeve cover 1 of the trocar, and the large U-shaped folded portion 2032 is opposite to the first A base 201 is protruding toward the side of the cannula cover 1 of the trocar. The drawings of this embodiment take this situation as the case. In this case, at this time, theoretically speaking, the small U-shaped folded portion 2031 and The distortion deformability of the S-shaped connecting portion 203 formed by the large U-shaped folded portion 2032 is affected by the convex height of the small U-shaped folded portion 2031 relative to the first base 201 and the convex height of the large U-shaped folded portion 2032 relative to the second base 202. The influence of the height of the rise, that is, the greater the height of the protrusion, the greater the space for the distortion of the S-shaped connecting portion 203. However, since the side of the casing cover 1 facing away from the trocar is the side where the fish-eye valve 100 is located, the fish-eye valve 100 is mainly formed to have good follow-up performance during the movement of the puncture needle, and it can also take into account good sealing performance. The piercing seal assembly including the swinging membrane 200 that needs to form the piercing seal assembly with the fisheye valve 100 has good followability, that is, the fisheye valve 100 is driven by the side of the first abutment 201 away from the casing cover 1 of the piercer. The integral puncture seal assembly moves along with the movement range of the puncture needle shaft. Here, considering that the distortion space of the S-shaped connecting portion 203 is effectively ensured, it is also necessary to consider reducing the small U-shaped folding portion 2031 relative to the first The excessively high protrusion of the base 201 has an effect on the fisheye valve 100 driving the overall puncture sealing assembly along with the movement of the puncture needle. The height of the small U-shaped fold 2031 designed in this embodiment relative to the protrusion of the first base 201 It is smaller than the height of the protrusion of the large U-shaped folded portion 2032 relative to the second base 202. That is to make full use of the raised height of the large U-shaped folded portion 2032 toward the side of the cannula cover 1 of the trocar to provide a relatively large space for distortion and deformation of the S-shaped connecting portion 203, combined with the control of the small U-shaped folded portion 2031 relative to the second The height of the protrusion of a base 201 satisfies the need to provide space for twisting and deformation of the S-shaped connecting portion 203, and at the same time reduces the impact on the fisheye valve 100 driving the puncture seal assembly and the overall formation of the puncture needle shaft.
此外,对于S形连接部203的扭曲变形性来说,除了会受到小U形折叠部2031相对于第一基台201的凸起高度和大U形折叠部2032相对于第二基台202的凸起高度的影响,还会受到小U形折叠部2031的两个侧壁之间的间距和大U形折叠部2032的两个侧壁之间的间距大小的影响,此处,对于小U形折叠部2031的两个侧壁之间的间距与大U形折叠部2032的两 个侧壁之间的间距可以是相同,也可以是不相同,例如通过设计小U形折叠部2031的两个侧壁之间的间距大于大U形折叠部2032的两个侧壁之间的间距,以对小U形折叠部2031相对于第一基台201凸起的高度小于大U形折叠部2032相对于第二基台202凸起的高度的补偿,由此来提高小U形折叠部2031对于的S形连接部203扭曲变形性的贡献。In addition, for the twisting and deformability of the S-shaped connecting portion 203, in addition to being affected by the protrusion height of the small U-shaped folded portion 2031 relative to the first base 201 and the large U-shaped folded portion 2032 relative to the second base 202 The height of the protrusion is also affected by the distance between the two side walls of the small U-shaped folded portion 2031 and the distance between the two side walls of the large U-shaped folded portion 2032. The distance between the two side walls of the U-shaped folded portion 2031 and the distance between the two side walls of the large U-shaped folded portion 2032 may be the same or different, for example, by designing the two side walls of the small U-shaped folded portion 2031. The distance between the two side walls is greater than the distance between the two side walls of the large U-shaped folded portion 2032, so that the raised height of the small U-shaped folded portion 2031 relative to the first base 201 is smaller than that of the large U-shaped folded portion 2032. With respect to the compensation of the height of the protrusion of the second base 202, the contribution of the small U-shaped folded portion 2031 to the twisting and deformability of the S-shaped connecting portion 203 is improved.
