Technical Field

The invention relates to the technical field of animal experiment equipment, in particular to an adjustable guinea pig application fixator based on 3D scanning and printing.

Background

Guinea pigs, also known as guinea pigs, and guinea pigs. Guinea pigs are small, gentle and easy to grasp, sensitive to many bacteria, viruses and drugs, and have some special biological characteristics and physiological anatomical features, and thus are widely used in various fields of biomedicine.

Sensitization test is a test for judging whether a test object is an allergen and sensitization intensity, two guinea pig test methods are used for measuring skin sensitization activity of chemicals and medical instruments at present, and are a closed application test and a guinea pig maximum dose test, the two methods consist of two stages of induction and excitation and relate to the whole process of hypersensitivity reaction, and the two test methods both need to fix a patch with a test article on a guinea pig body for hours to days. The test application can be made of filter paper or absorbent gauze.

Currently, the desensitization adhesive tape is mostly used for fixing the application on a guinea pig body, and the following problems are easy to occur: 1. increasing the workload of the test personnel. The guinea pig can break away to be fixed in applying ointment or plaster on one's body and tear and sting, for guaranteeing that the time of applying ointment or plaster reaches the standard requirement, needs the testing personnel to keep paying attention to the state of applying ointment or plaster, in time takes the measure to prevent to apply ointment or plaster and drops. 2. Affecting the reliability and accuracy of the test result. When the patch is fixed, the patch can be adhered to the hairs on the cavy abdomen by using a desensitizing adhesive tape, and when the patch is removed, the adhered hairs are pulled out along with roots, so that the skin is stimulated, and the judgment of a test result is influenced. 3. Further improving the welfare requirement of animals. In sensitization tests, multiple sticks and removals of desensitizing patches and multiple grabs all caused physiological and psychological damage to guinea pigs.
