Problems solved by technology

Due to the high production cost of large-scale low-pressure hypoxic animal model cabins, high requirements for supporting facilities, large installation area, high operation and maintenance costs and other factors, the wide application is limited.
At present, the hypobaric and hypoxic animal model cabins are developing towards medium and small sizes; the current type of hypobaric and hypoxic animal model cabins cannot reach the vacuum degree at ultra-high altitudes, and cannot meet the experimental requirements of acute hypobaric hypoxia at ultra-high altitudes. Acute high-altitude injury experiments have been completed, so there is an urgent need for a pressure vessel cabin that can meet the needs of a low-pressure hypoxic animal model cabin

Embodiment 1

[0067] Embodiment 1. Verification of high vacuum degree pressure vessel cabin

[0068] First of all, the visual observation tube body 2 can be made of high-strength acrylic material, and the high-strength acrylic material is used as the cabin body of the low-pressure hypoxic animal model cabin, and its two ends are equipped with metal heads, and they are used with self-sealing inner flanges The tight connection of vacuum forms a visible pressure vessel compartment, such as figure 1 shown.

[0069] The design of the cabin volume: The previous experimental data confirmed that the number of experimental animals in the pressure vessel cabin with a certain volume exceeds the standard, that is, the volume ratio of the experimental animals is too high, which will lead to the imbalance of temperature and humidity regulation in the experimental cabin, high temperature and high humidity, and the experimental environment. Stress, oxygen levels drift, and even animal death occurs.

Embodiment 2

[0082] Embodiment 2. Self-enclosed inner flange structure

[0083] The invention provides a self-sealing inner flange used for connecting two different materials, connecting the acrylic cabin body and the metal heads at both ends to realize the connection and sealing between different materials, such as figure 2 , 3 shown.

[0084] The acrylic cabin body and the first flange 101 at both ends are bonded seamlessly. The width of the first flange 101 is 7.5cm and the thickness is 2.5cm. There are 12 through holes for M20 strong bolts evenly distributed on the first flange 101 . The width of the first flange 101 in the acrylic is the same as that of the metal second flange 102 on the metal head, and the position of the through hole of the strong bolt is the same size, so that after the first flange 101 and the second flange 102 are docked, the through hole of the strong bolt coincide.

[0085] A rubber gasket is placed between the first flange 101 and the second flange 102, a...

Embodiment 3

[0091] Embodiment 3. Seal ring structure

[0092] The airtight door is a channel for the pressure vessel cabin to communicate with the outside world, and the airtightness after the airtight door is closed is an important guarantee for the pressure maintenance of the pressure vessel cabin.

[0093] Such as image 3 As shown, a sealing groove 151 is provided at the inner side of the sealing door where it is docked with the self-sealing welding cover 103, and a sealing ring with a certain deformation capacity is placed therein. As the hatch body 6 is gradually tightened, the contact with the hatch door is gradually increased. area, to ensure the airtightness of the airtight door.

[0094] Closing the sealed door to realize sealing includes three processes, namely: the door body 6 is in contact with the gasket, the door body 6 rotates, and the door body 6 is tightened to squeeze the gasket.

[0095] Such as Figure 4 As shown, the present invention provides a sealing ring, whic...

Abstract

The invention provides a pressure vessel cabin of a low-pressure hypoxic animal model cabin, which includes a visual observation pipe body and metal heads at both ends, which are vacuum-connected by a self-sealing inner flange; one end of the metal head contains a hermetic door , the door shell is provided with an annular sealing groove, and a nested sealing ring is placed in the sealing groove, and the sealing door is tightly connected with the metal head when it is closed; the nested sealing ring includes a sealing outer ring and a sealing ring. The inner core ring and the sealed outer ring are provided with a space for accommodating the sealed inner core ring, and the sealed inner core ring is nested in the sealed outer ring. Beneficial effects of the present invention: the pressure container cabin of a low-pressure hypoxic animal model cabin is set up, the vacuum degree reaches 11.5KPa, and the bulkhead can withstand the internal and external pressure difference of 89.8KPa, which meets the requirements of ultra-high altitude low-pressure hypoxic animal experiments, and can be maintained stably Simulate the pressure level at an altitude of 10,000 meters.

Description

technical field [0001] The invention belongs to the field of animal experiment devices, in particular to a pressure vessel cabin of a low-pressure hypoxic animal model cabin. Background technique [0002] The low-pressure hypoxic animal model cabin is a device for simulating the plateau low pressure and low oxygen partial pressure experimental environment, and is used to prepare high-altitude hypoxic animal models. Due to the high production cost of large-scale low-pressure hypoxic animal model cabins, high requirements for supporting facilities, large installation area, and high operation and maintenance costs, the wide application is limited. At present, the hypobaric and hypoxic animal model cabins are developing towards medium and small sizes; the current type of hypobaric and hypoxic animal model cabins cannot reach the vacuum degree at ultra-high altitudes, and cannot meet the experimental requirements of acute hypobaric hypoxia at ultra-high altitudes. Acute plateau ...
