Description

Rhesus monkey head tube protection cap

technical field

The invention relates to an animal experiment auxiliary device, in particular to a rhesus monkey head implant tube protection cap.

Background technique

With the development of life sciences, experiments related to rhesus monkeys, which have a high degree of similarity to human internal and external environments, have gradually become a hot spot in biological experiments. However, we encountered difficulties when it came to brain implants in rhesus monkeys. Due to the monkey's active nature and sensitive hands, it is possible to pull out the implanted catheter at any time in the awake state, and these catheters are often implanted through painstaking operations; and threaten the life of the rhesus monkey itself. But there is no relevant product on the market now. In the actual application process, most of them are simple devices, which can only be used for a short period of time and under anesthesia in monkeys, which has great restrictions on related experiments in rhesus monkeys; it has a great impact on the quality of life of experimental animals and is prone to complications such as infection; it needs to be invasive Sexual implant fixation and even surgical manipulation have ethical issues in animal testing.

Contents of the invention

The present invention aims to provide a rhesus monkey head planting tube protective cap, which is easy to wear and durable, and can well protect the test planting tube in the cap; meanwhile, it does not affect the daily water and food intake of rhesus monkeys ,Activity.

In order to achieve the above object, the present invention is achieved by adopting the following technical solutions:

The rhesus monkey head planting tube protection cap disclosed by the invention comprises a cap shell, a cap liner, and a collar. There are gaps running through the bottom edge, there are 3 gaps, and there are gaps between the gaps, the bottom of the gap is provided with a through groove, the collar is ring-shaped, and the collar passes through the through groove in turn; The cap liner is located in the cap shell, and there is a gap between the cap liner and the inner surface of the cap shell. The cap liner is connected to the sliding ring through a slide button, and the sliding ring is connected to the inner wall of the cap shell. The sliding ring can rotate 360 degrees, which is convenient for different parts plant tube. When the top of the hat is hit, the force point cannot stay for a long time or slip off; and the force borne by the top of the hat can be transmitted to the surroundings, and the force reduced by the cushion of the hat lining can reach more than 2/3, and the rest of the force is transmitted through the entire area of the hat lining For the skull of the monkey, the point of force has become the surface of force, thereby avoiding the stress concentration of the impact force on a certain point on the cap shell and reducing the force per unit area. The collar is just located at the junction plane between the jaw and the neck of the monkey, which can stabilize the monkey hat to the greatest extent, prevent the monkey hat from shifting up and down, and fix the gap area of the face within a limited range. The face and ears of the rhesus monkey are exposed through the notch, which facilitates the daily water intake, eating, and activities of the rhesus monkey, and improves wearing comfort; the interval between the notches can stabilize and prevent the shell from shifting or rotating.

Further, the cap shell is provided with ventilation holes. There can be multiple air holes, such as on the top circumference of the cap shell, the rear portion of the cap shell, and the intervals are convenient for ventilation.

Further, the inner surface of the cap shell and the cap liner are both provided with a buffer pad A; the bottom of the cap shell is provided with a buffer pad B; the bottom surface of the buffer pad B is lower than the collar. When an impact occurs, it can reduce the impact force on the monkey's neck and head.

Further, the edges of the three notches are provided with anti-wear rings; possible friction damage to the face of the monkey ears during wearing can be avoided.

Preferably, the gap is 25-50mm. These gaps can first place the pipes needed for the test, and when the monkey moves and impacts the safety helmet, the cap shell will not directly affect the test planting pipe in the top of the head due to force deformation;

Preferably, the material of the cap shell is polycarbonate; it is strong and wear-resistant while being convenient to wear.

The present invention adopts an overall design, which is convenient to wear and durable, and can well protect the test planting tube in the cap; meanwhile, it does not affect the daily water intake, food intake and activities of rhesus monkeys. In terms of animal experiment ethics, since the cap is an external device, it is different from previous implantation or trauma methods. The animal is comfortable to wear, and will not cause unnecessary operational damage to the animal, improving the quality of life of the animal.
