The invention discloses a device for a hemodynamic monitoring catheter penetrating through the bulkhead of a low-pressure hypoxic cabin, which includes a rubber plug, the rubber plug includes a cylindrical body, a middle hole is arranged in the middle of the cylindrical body, and two ends of the cylindrical body are arranged Cylindrical grooves, along the axial length of the cylindrical body, arc cuts are provided from the middle hole to the outer surface of the cylindrical body; two assembled knobs are also included, and each assembled knob is composed of two half-knobs of the same shape Relatively arranged, the middle part of the half knob is provided with a groove with a semicircular cross-section, and the inner surface of the groove is provided with a rubber pad to ensure the sealing of the hemodynamic catheter when it passes through the assembled knob. The device of the present invention can realize the The hemodynamic monitoring catheter runs through the bulkhead of the hypobaric hypoxic chamber. In the closed environment of the hypobaric hypoxic chamber, invasive hemodynamic monitoring and blood drawing for arterial blood gas analysis are carried out to ensure the aseptic principle of various experimental operations.
Description
technical field [0001] The invention relates to the field of experimental equipment for preparing rat models in a low-pressure hypoxic chamber simulating a high-altitude low-pressure hypoxic environment, in particular to a device in which a hemodynamic monitoring catheter in a closed environment for experimental rats penetrates through the bulkhead of a low-pressure hypoxic chamber. Background technique [0002] In the plateau environment with an altitude of more than 3000 meters, low pressure and low oxygen have a huge impact on the human body. Diseases caused by plateau hypobaric hypoxia are the research focus of plateau medicine and anti-hypoxic medicine, and the preparation of hypobaric hypoxia experimental animal models is an important means to realize scientific research in this field. [0003] In recent years, the research on animal models of hypobaric hypoxic injury is at the bottleneck stage. The animal models of hypobaric hypoxia are not stable enough, and more eva...
