Ventilator Connection Socket With Removable Inlet Filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The maintenance of medical ventilator connection sockets, particularly NIST or DISS type sockets, is cumbersome due to the need to dismantle and reassemble the socket to replace filters, which can lead to prolonged maintenance interventions and risks of equipment deterioration.
Innovation Solution
A medical ventilator with an integrated connection socket featuring an extractable filtration element that can be inserted or extracted through the inlet port of the socket body, eliminating the need to dismantle the socket for filter replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter is inserted into a chamber fitted in the internal passage of the socket body, then the gas can be filtered, but the socket must be dismantled and reassembled for filter replacement
Solution Approach 1:
The connection socket is divided into separable components: the socket body and the filter element. The filter element can be independently removed from the socket body through the inlet orifice without dismantling the entire socket assembly, enabling easy maintenance while maintaining gas filtration functionality.
Solution Approach 2:
The filter element is extracted as a separate, removable component from the socket body. It can be taken out through the inlet orifice for replacement without disassembling the socket, thus maintaining filtration capability while simplifying maintenance operations.
2Reliability
If the socket is dismantled for filter replacement, then the filter can be replaced, but the maintenance time increases and equipment is immobilized
Solution Approach 1:
The filter element is designed to be pre-positioned in the socket body through the inlet orifice. This preliminary arrangement allows the filter to be easily accessed and replaced through the same inlet opening without requiring socket disassembly, significantly reducing maintenance time and keeping the equipment operational.
3Reliability
If the filter is permanently fixed in the socket body, then the gas circuit is protected, but the filter cannot be easily replaced
Solution Approach 1:
The filter element transitions from a fixed to a movable state within the socket body. It can be easily inserted and removed through the inlet orifice, providing both gas circuit protection during operation and ease of replacement during maintenance without requiring socket disassembly.

AI summary
The invention relates to a medical ventilator (10) comprising an internal gas circuit (12) in fluidic communication with a connection port (1), preferably of the NIST or DISS type. The port comprises a port body (2) with an internal passage (3) connecting an inlet port (4) and an outlet port (5), and comprising flow control means (6, 7). A filter element (8) is arranged in the internal passage (3) of the port body (2). The filter element (8) is mounted in a removable manner within the internal passage (3) of the port body (2). Insertion or extraction of the filter element (8) is carried out through the inlet port (4) of the internal passage (3) located on the free proximal end (1a) of the port body (2).
