Problems solved by technology

Another problem is that the pressure applied to the puncture opening is in some cases too high, with the risk of blocking circulation in the body part involved, and in some cases with too low pressure, with the risk of hematoma formation

Embodiment Construction

[0032] figure 1 An exemplary illustration shows a not-to-scale longitudinal section through a closure device 1 adhered in a definable position, while figure 2 For this it is shown according to figure 1的闭合装置1的仰视图。闭合装置1含有闭合元件2和压力体3,其在该示例中由带有弹性特性的材料(例如硅酮)一件式地来构造。压力体3为近似透镜状的形成物且用来施加压力以用于闭合穿刺开口(未显示)。

[0033] 此外,二个保持带4作为闭合元件2的末端提供在闭合元件2的远端处。保持带4具有非弹性特性。例如,保持带4可与闭合元件2一件式地来构造。为了使保持带4获得非弹性特性,例如将加强层5安装到保持带4上。加强层5又由带有非弹性特性的材料形成。加强层5可借助于传统的(工程上的)粘合剂6粘附到保持带4上。在一种情况下,在其中保持带4由硅酮制成,可必需的是以合适的方式准备带有粘合剂6的接触面。为了改善硅酮与所使用的粘合剂6的持久的接触,可为此设置表面处理,例如等离子处理、电晕处理、湿化学处理或其他的处理。

[0034] 备选地,共同的材料(闭合元件2和保持带4由该材料一件式地来构造)如此通过例如有针对性的硬化加工流程来处理,即唯独仅不允许在保持带4的区域中的材料伸展,而剩余的区域可继续伸展。

[0035] 虽然在附图中未进行显示,保持带4和闭合元件2可包含不同的材料,其彼此相连接。在该示例中,闭合元件2可包含硅酮,而保持带4可包含聚乙烯(PE)。

[0036] 在加强层5的下侧处提供有皮肤粘结层7以用于粘附到皮肤上。皮肤粘结层7优选具有皮肤粘合专用的特性。最后,皮肤粘结层7还可附加地设有可取下的保护薄膜(未示出)。

[0037] 此外,闭合装置1在闭合元件2的区域中含有两个指示元件8,其与闭合元件2相连接。在一种实施方式中,指示元件8与闭合元件2一件式地来构造。指示元件8在此在压力体3两侧优选在相同间距的情况下来布置。指示元件8设计成呈现可随着由于施加拉力到闭合装置1(和因此到闭合元件2)上逐渐延伸而改变的几何结构,该可变性与延伸和因此与...

Abstract

A closure device (1) which can be adhered in a defined position for closing opened blood vessels has a closure element (2) and a pressure body (3), said closure element (2) being made of a material with elastic properties. The closure device (1) further contains a plurality of retaining strips (4) which adjoin distal ends of the closure element (2). The retaining strips (4) are provided with a reinforcing layer (5) at least in some regions, said reinforcing layer being made of a material with non-elastic properties. The closure device also contains at least one indicator element (8) which is connected to the closure element (2). The advantages consists in a simple design of the adhesive closure device (1) and in that the closure device can be handled easily even by laypeople.

Description

technical field [0001] The invention relates to a closure device according to claim 1 for closing a pierced blood vessel. [0002] In particular, the invention relates to a positionally definable adhesive closure device for closing a punctured blood vessel with a pressure body suitable for contacting the wound. Background technique [0003] In the field of medical applications, especially in the puncture of blood vessels, there is still a constant need to provide closure devices (hereinafter also referred to as Vascular closure), with which not only the subsequent outflow of blood into the free space outside the body or the loss of blood into the free space outside the body is prevented, but also the outflow of blood into the tissue (formation of a hematoma), wherein, but at the same time, it should not The vitally important blood circulation inside the body is impeded after successful application of the closure device. [0004] Traditionally, the puncture site of the bloo...
