Description

Technical Field

[0001] This utility model relates to the field of blood gas analysis technology, specifically to a liquid-filled connector structure. Background Technology

[0002] Wet blood gas analyzers use electrochemical methods to accurately and comprehensively reflect the body's cardiopulmonary function and tissue metabolism by dynamically monitoring parameters such as blood gas and acid-base homeostasis. This is of great significance for the formulation, implementation, and modification of surgical plans.

[0003] Traditional blood gas analyzers use electrodes to measure relevant indicators such as pH, partial pressure of carbon dioxide, and partial pressure of oxygen in arteries within a short period of time to assess a patient's respiratory and metabolic functions. Newer blood gas analyzers have evolved from simple acid-base balance measurements to comprehensive monitoring of critical care parameters that meet the requirements of modern clinical medicine. These systems can provide a comprehensive diagnosis of cardiopulmonary function, liver and kidney function, acid-base balance, oxygenation status, and metabolic function, facilitating a comprehensive and accurate analysis of respiratory status. This provides a reliable basis for the diagnosis and treatment of critically ill patients and is a crucial indicator in the monitoring of critically ill patients.

[0004] Blood gas analyzers utilize a switching valve to achieve multi-channel fluid supply. Rotation of the valve switches between different flow paths, thus changing the fluid path. The fluid path connects to the fluid reservoir via a connector structure. Existing technology uses a sliding structure at the connector, requiring a pull hook to extend the valve core to open the fluid path. This adds an extra step to moving the valve core, making operation inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide a liquid-filled connector structure that can effectively solve the technical problem in the prior art where the valve core must be pulled out by a hook to achieve liquid circuit conduction, resulting in inconvenient operation.

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] See above Figures 1-4This embodiment discloses a liquid-filled connector structure, including a connector body 102 for connecting with a liquid-filled container 101. This embodiment also includes a movable core 103. The connector body 102 is provided with a flow channel 104 and a slide 105. The movable core 103 includes a core 106 and a guide block 107 fixedly connected to the core 106. The guide block 107 is slidably disposed in the slide 105.

[0035] The core 106 is provided with a first notch 108, and a first sealing ring 109 and a second sealing ring 110 are provided on the core 106. The first notch 108 is located between the first sealing ring 109 and the second sealing ring 110. The connector body 102 is provided with a liquid outlet channel 111 connected to the slide 105. The connector body 102 is used to connect to the liquid package 101. The slide 105 is connected to the liquid package 101. The connector body 102 is provided with a liquid outlet pipe connected to the liquid outlet channel 111.

[0036] Among them, a first flow channel 112 is provided on the slide 105 near the liquid package 101. After the core 106 moves, the liquid outlet channel 111, the first notch 108 and the first flow channel 112 are interconnected.

[0037] In practice, a top post is provided in the liquid package 101 component placement area of ​​the analyzer. The top post corresponds to the moving core 103. Once the top post contacts the moving core 103, the moving core 103 can be driven.

[0038] In practical use, this invention slides the movable core 103 onto the connector body 102 and achieves sealing through the first sealing ring 109 and the second sealing ring 110. By driving the movable core 103 to move within the connector body 102, the liquid outlet channel 111 and the first flow channel 112 are connected, facilitating the entry of reagents into the liquid outlet channel. In this application, the movable core 103 is moved by pushing. When the liquid package 101 assembly is placed in the analyzer, the movable core 103 is driven by a top post in the analyzer corresponding to the movable core 103 on the connector body 102. After the liquid package 101 assembly is installed, the liquid outlet channel 111 and the first flow channel 112 are connected, facilitating the liquid outlet. This invention effectively solves the technical problem in the prior art where the valve core must be pulled out by a hook to achieve liquid circuit connection, resulting in inconvenient operation.

[0039] Furthermore, there are multiple first flow channels 112, evenly distributed on the inner wall of the slide 105. The multiple first flow channels 112 facilitate smooth reagent flow and ensure reagent flow rate.

[0040] The core 106 is provided with a first mounting groove 113 and a second mounting groove 114, and a first sealing ring 109 and a second sealing ring 110 are respectively disposed in the first mounting groove 113 and the second mounting groove 114. The first mounting groove 113 and the second mounting groove 114 can fix the first sealing ring 109 and the second sealing ring 110, preventing displacement when the movable core 103 moves.

[0041] Furthermore, the guide block 107 is provided with a guide protrusion 115, and the inner wall of the slide 105 is provided with a groove 116 corresponding to the guide protrusion 115. The guide protrusion 115 and the groove 116 provide a way to allow the moving core 103 to slide stably within the connector body 102 after the connector body 102 is installed on the housing of the liquid package 101 assembly.

[0042] In practical use, to prevent leakage from occurring if the reversing valve in the detector does not turn to the closed position after the test is completed, a reset unit 117 is installed in the slide rail. The reset unit 117 is used to drive the moving core 103 to reset. The reset unit 117 is a reset spring installed in the slide rail 105 and fitted onto the core 106.

[0043] Furthermore, the guide block 107 is provided with a recess 118, and an outwardly inclined thrust arm 119 is provided in the recess 118. A thrust groove communicating with the slide 105 is provided on the connector body 102. The thrust arm 119 can limit the guide block 107 and prevent the guide block 107 from coming out of the connector body 102.

[0044] The connector body 102 is provided with a limiting part 120, and a first elastic arm 121 is inclinedly provided on the connector body 102, forming a snap-fit ​​fixing area between the first elastic arm 121 and the limiting part 120. The limiting part 120 enables the connector body 102 to be installed quickly, improving the overall assembly speed.

[0045] Furthermore, an elastic pad is provided on the limiting part 120 near the first elastic arm 121. The elastic pad makes installation more convenient. When the elastic pad is squeezed, it makes room for the first elastic arm 121 to come into contact with the housing of the liquid package 101 assembly. Then, the elastic pad returns to its original position to achieve the purpose of fixation.
