Detailed Description
In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The invention provides a film coating device of a medical percutaneous oxygen and carbon dioxide probe, which can be assembled quickly and simply, can achieve excellent sealing effect, greatly improves the accuracy of the measured values of the medical percutaneous oxygen and carbon dioxide probe, and is beneficial to signal conduction and accurate control.
As shown in fig. 1 and 2, the membrane applying device of the medical percutaneous oxygen and carbon dioxide probe comprises an upper membrane shell 1 and a breathable membrane 2, wherein the upper membrane shell 1 is annular, and the lower surface of the upper membrane shell is the same horizontal plane; go up the middle part of membrane casing 1 and be provided with the O type circle spacing groove 7 that holds O type sealing washer 3, will O type circle spacing groove 7 department is arranged in to ventilated membrane 2, then impresses ventilated membrane 2 with O type sealing washer 3 in O type circle spacing groove 7, fixed ventilated membrane 2.
The O-shaped ring limiting groove 7 is of a structure that the lower opening is larger than the upper opening and is concave inwards, so that the O-shaped sealing ring 3, the breathable film 2 and the upper film shell 1 are conveniently and quickly matched tightly, the limiting is accurate, and the sealing performance of the structure is ensured; the bottom of the upper membrane shell 1, the bottom of the breathable membrane 2 and the bottom of the O-shaped sealing ring 3 are flush, and the structure is tightly matched and sealed with the medical percutaneous oxygen and carbon dioxide probe 9.
The lower end of the O-shaped sealing ring 3 is provided with an inward-protruding O-shaped sealing ring inner protrusion 6, and the O-shaped sealing ring inner protrusion 6 is used for being accurately aligned with a sealing groove of the sensor probe, so that the sealing effect is achieved, and the influence of exogenous gas on the accuracy of the measurement value of the sensor probe is prevented.
