Embodiment 1

[0023] Example 1: see attached Figures 1 to 6 , a non-human primate experimental animal medium and long-term simulated weightlessness model device, characterized in that: it includes a device main frame 100, a horizontal body position positioning device, a trunk roll angle positioning device, a bed surface 403, a feeding device 600, a water inlet device 700, 500 metabolite collection trays, 410 fastened vests for test animals;

[0024] The main frame 100 of the device is a bed frame structure with guardrails on the left and right sides;

[0025] The horizontal body position positioning device includes a bed surface outer ring 401, a connecting shaft 201, a locking handle 203, a scale 202 and an angle pointer indicating the inclination angle of the bed surface outer ring 401, and the bed surface outer ring 401 passes through the The connecting shaft 201 is connected to the left and right sides of the device main frame 100 and is locked and fixed by the locking handle 203;

Embodiment 2

[0032] Example 2: see attached Figures 1 to 6 , a non-human primate experimental animal medium and long-term simulated weightlessness model device as described in Example 1, the bed surface 403 material is a canvas with a soft thin steel plate in the interlayer, because this material has certain flexibility and air permeability , which can slow down the damage to the skin of monkeys during long-term immobilization and emotional agitation, and the soft thin steel plate in the canvas interlayer plays the role of spinal support.

Embodiment 3

[0033] Example 3: see attached Figures 1 to 7 , according to the non-human primate experimental animal medium and long-term simulation weightlessness model device described in Embodiment 1 or 2, it also includes balls, mirrors and other puzzles that are placed in the middle of the upper part of the main frame 100 of the device respectively for playing A game-like entertainment security device 800, and a medical treatment and surgical rehydration rack 900. The entertainment security device 800 is to reduce and eliminate the fear and emergency response of the subject animal being fixed on the experimental table for a long time, and to attract and divert its attention; Treatment of diseases or surgical rehydration and anesthesia for research purposes.

Abstract

The invention belongs to the technical field of aerospace medicine and in particular relates to a device for performing a physiological test by simulating microgravity. The technical scheme is that the non-human primate test animal medium and long-term weightlessness simulation model device comprises a device main frame (100), a horizontal body position positioning device, a trunk side inclined angle positioning device, a feeding device (600), a water intake device (700) and a metabolin collecting disc (500), wherein a bed surface outer ring (401) of the horizontal body position positioning device is connected to the device main frame (100) through a connecting shaft (201) and is fixed by a locking handle (203); a bed surface inner ring (402) of the trunk side inclined angle positioning device is connected to the bed surface outer ring (401) through a positioning shaft (303) and is fixed by a locking device; and the metabolin collecting disc (500) is arranged below the device main frame (100). According to the invention, head low-position inclined angle and trunk side inclined angle can be positioned precisely by positioning and locking devices, and various zero-gravity environments can be simulated.

Description

technical field [0001] The invention belongs to the technical field of aerospace medicine, and particularly relates to a device for simulating microgravity for carrying out physiological experiments. Background technique [0002] When astronauts are in spaceflight, they are in a space environment dominated by weightlessness effects, combined with radiation, noise and other factors. Among them, the mid-to-long-term weightlessness effect can lead to bone loss, muscle atrophy, cardiovascular dysfunction, and decreased immune function in astronauts, which directly affects astronauts' ergonomics, health and life safety. Therefore, it is necessary to conduct multi-level mechanism research on the physiological effects of mid- and long-term flight weightlessness. [0003] The use of experimental animals to establish effective animal models to study the physiological effects of medium and long-term spaceflight has always been an important means of aerospace medical research. Non-hu...
