Benefits of technology

This patented technology describes a system that uses controlled temperatures (water), a removably attached clamp or other means to hold experiments on small rodents like rats. A special apparatus called this system allows researchers to study these tiny organisms more efficiently while also ensuring they don’t hurt their own body when experimented with them.

Problems solved by technology

The technical problem addressed by this patented technology relates to developing an effective way to prepare animals that can cause damage or discomfort during laboratory tests such as gastrointestinal (GI) testing without causing harm themselves.

Embodiment 1

[0032] Such as figure 1 As shown, the device for preparing the stress gastric mucosal injury model of the present invention mainly consists of a constant temperature water bath, a rat cage lifter 2, a rat cage, a heating rod 8, a temperature sensor 9, a control circuit 10, a control circuit operating power supply 11, The heating rod power switch 12 and the heating rod power supply 13 are composed;

[0033] The water bath housing 1 of the constant temperature water bath is provided with a water tank, and a squirrel cage lifter 2, a heating rod 8, and a temperature sensor 9 are also installed in the water bath housing 1; one side of the water bath housing 1 is provided with an electrical box, Control circuit 10, control circuit working power supply 11, heating rod power switch 12 and heating rod power supply 13 are all installed in the electrical box; 9. Connect the control circuit 10 and the working power supply 11 of the control circuit in sequence, and the control circuit 10...

Embodiment 2

[0042] Example 2 Preparation process of animal model of stress gastric mucosal injury (rat is used as model animal)

[0043] 200-250 g SD rats were rapidly anesthetized with ether and placed in the cage, so that the head of the rat was inserted into the upper narrow part of the left and right splints, and the tightness of the left and right splints and the height of the bottom plate were adjusted to fix the rat’s body ; The mouse cage was fixed on the mouse cage lifter, and the screw of the mouse cage lifter was manually adjusted to adjust the water application depth of the rats, and the rats were immersed in the water for 4 hours to prepare a rat model of stress gastric mucosal injury.

[0044]

Embodiment 3

[0046] The degree of gastric mucosal injury was measured by gastric mucosal injury index.

[0047] The sum of the lengths of all lesions in the whole stomach is the injury index (expressed in mm): 1 point for lesion ≤ 1 mm (including erosion point); 2 points for 1 mm 4 mm; damage index doubles for damage width > 2 mm.

[0048]After using the device according to the present invention to make models according to the method described in the rat model-making process of the above-mentioned Example 2, the damage index increased significantly, from 0 in normal rats to 65 ± 65 in injury model rats. 7.6.

[0049] The results of the above examples show that the device is a standardized, normalized, simple in structure, convenient to use, and good effect device for preparing animal models of stress gastric mucosal injury; Flexible control of the watering depth of experimental animals improves the success rate of modeling. At the same time, it can strictly control the stability of exper...
