Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0020] The invention is a jig for membrane lung connection in extracorporeal circulation. The jig can make the installation and disassembly of the membrane lung very fast and convenient, and greatly saves operation time. The jig consists of two parts, one part is the fixed holder 1 fixed to the extracorporeal circulation support frame, and the other part is the membrane lung connecting flange 2 connected to the membrane lung 3, the outline is as follows figure 1 shown, for the sake of illustration in figure 1 A possible membrane lung has been added in , which will be omitted in subsequent figures.
[0021] The specific structure of the fixture is as follows: figure 2 As shown, the fixed deck includes a lifting cap 11, an upper end cover 12, a lifting plate 14 and a lower end cover 16 arr...

The invention discloses a clamp for connection of a membrane lung in an extracorporeal circulation, and belongs to the technical field of medical appliances. The clamp comprises a fixed clip seat and a membrane lung connecting flange, wherein the fixed clip seat comprises a lifting cap, an upper end cap, a lifting plate and a lower end cap which are sequentially connected from top to bottom, and four vertical clip columns are uniformly distributed on the annular circumference of the lower surface of the lifting plate; the lower end cap is connected with the upper end cap by virtue of a flange; four horizontal clip columns are uniformly distributed on the cylindrical side surface of the lower end cap; the membrane lung connecting flange is a round cylinder with a bottom, and a fixed hole connected to the membrane lung is formed in the bottom; a connector is arranged on the inner surface of the round cylinder; the membrane lung connecting flange and the fixed clip seat are detachably connected by virtue of the connector. According to the clamp, the membrane lung can be quickly assembled and disassembled by virtue of the membrane lung quick connecting flange only by means of lifting and rotating two actions, so that the membrane lung can be assembled and disassembled quickly and conveniently, and the operation time can be greatly reduced.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a fixture for connecting membrane lungs in extracorporeal circulation, which can realize rapid installation and disassembly of membrane lungs in extracorporeal circulation. Background technique [0002] Membrane oxygenator, referred to as "membrane lung", is mainly used to oxygenate blood and remove carbon dioxide in extracorporeal assisted circulation. It is a new type of oxygenator that has been widely used in recent years. Compared with other types of oxygenators, it has It has the characteristics of high gas transfer efficiency and slight damage to blood, and is the core component of extracorporeal assisted circulation. When extracorporeal assisted circulation equipment is needed to assist surgery, it is necessary to quickly set up extracorporeal bypass to reduce the time of cardiac arrest. At the same time, for long-term operations, it may also involve the need to re...
