Description

Technical Field

[0001] This utility model relates to the field of blood gas analysis technology, specifically to a guiding and positioning structure for blood gas reagent components. 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] In the existing technology, when the liquid bag is placed on the mechanism base, due to errors in manufacturing and assembly, the liquid bag and the contact pin assembly are prone to misalignment and failure to make contact, which affects the positive detection. Utility Model Content

[0005] The purpose of this invention is to provide a guiding and positioning structure for a blood gas reagent assembly, which can effectively solve the technical problem in the prior art where the liquid bag and the stylus assembly are prone to inaccurate positioning due to assembly and manufacturing errors.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A blood gas reagent assembly guide and positioning structure includes a detection plate mounting bracket for mounting on a core base, a stylus assembly on the detection plate mounting bracket, and a guide post on the detection plate mounting bracket.

[0008] The detection plate mounting bracket is provided with several mounting holes, and each mounting hole is provided with an elastic gasket. The mechanism base is provided with mounting pins at positions corresponding to the mounting holes. The diameter of the mounting pins is smaller than the diameter of the mounting holes. The elastic gaskets are located between the mounting holes and the mounting pins. The mounting pins are provided with fixing units for fixing the detection plate mounting bracket to the mechanism base. The guide post passes through the mounting groove provided on the mechanism base.

[0009] Furthermore, the end of the guide post has a guide slope, and a guide portion is formed at the guide slope.

[0010] Furthermore, the end of the guide post has a hemispherical structure.

[0011] Furthermore, the stylus assembly includes a stylus PCB board and a plurality of stylus pins disposed on the stylus PCB board. The detection board mounting bracket is provided with a first mounting groove, and the stylus PCB board is fixedly disposed in the first mounting groove.

[0012] Furthermore, the fixing unit includes screws for securing the detection plate mounting bracket to the mechanism base.

[0013] Furthermore, the elastic gasket is made of rubber or silicone material.

[0014] Furthermore, a heating unit is installed on the mounting bracket of the detection plate.

[0015] Furthermore, the heating unit includes insulation cotton and a heating film. The insulation cotton is placed on the mounting bracket of the detection plate, and the heating film is attached to the insulation cotton. The insulation cotton has clearance holes.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In practical use, this invention uses elastic gaskets to flexibly mount the detection plate mounting bracket onto the mechanism base, allowing the entire mounting bracket to be movable. When the liquid bag is placed on the mechanism base, the guide post engages with the guide hole on the liquid bag, ensuring accurate contact between the stylus assembly and the blood gas simulation card PCB board on the liquid bag. This achieves rapid positioning and alignment, effectively solving the technical problem in existing technologies where manufacturing and assembly errors can lead to inaccurate positioning and contact between the stylus assembly and the liquid bag, affecting positive detection.
