Description
Technical Field
The utility model relates to the technical field of medical treatment and laboratory equipment, in particular to a device for preventing rodent bites.
Background
Rodents are usually small and medium-sized mammals having a pair of chisel-shaped incisors, each of their upper and lower jaws having a pair of chisel-shaped incisors with enamel only at the front edge, grow for life, and the lower jaw can move back and forth, suitable for grinding food. In medical research, rodents such as guinea pigs, mice, rats, etc. are often used as experimental animals to perform procedures such as blood collection, gastric lavage, and immunization injection. In order to achieve better experimental results, the operation of such experimental animals in the experiment should be performed on the basis of causing no pain, conforming to the physiological characteristics and reducing stress as much as possible. Therefore, the bare-handed operation in the animal experiment has certain skill and difficulty, has certain potential safety hazard, and the improper operation can be bitten by the rodent. Some existing tools can assist animal experiment operation, and reduce the probability of being bitten by experimenters. For example, patent CN204092261U discloses a rodent head fixator for fixing the head by fixing the teeth of a mouse. Patent CN105147412A discloses a mouse tweezers, and the laboratory technician uses this mouse tweezers to avoid bare-handed contact mouse, conveniently snatchs fixed mouse, has reduced the probability that the finger was bitten by the mouse.
However, the devices in the prior art are often fixed in structure and shape, are not easy to deform, and cannot be well adjusted in shape to adapt to the shapes of different individual animals and fit the bodies of the animals in use.

In order to solve the technical problems, the utility model provides a device for preventing rodent bite, which comprises an elastic metal strip and an elastic cloth belt, wherein the elastic metal strip is provided with a plurality of holes, the elastic cloth belt is matched with the elastic metal strip, the elastic cloth belt is positioned on one side of the elastic metal strip, the interval between every two adjacent holes is larger than 3 mm, and two ends of the elastic cloth belt respectively penetrate out of two different holes in the elastic metal strip.
As an improvement, the middle of the elastic metal strip is provided with a tooth containing groove, an opening of the tooth containing groove is formed in one side, close to the elastic cloth belt, of the elastic metal strip, and an included angle between the extending direction of the tail end of the tooth containing groove and the plane where the elastic metal strip is located is smaller than 90 degrees.
As a further improvement, the inner wall of the tooth containing groove is provided with saw-toothed protrusions.
As a further improvement, a flat tubular cavity is arranged in the tooth accommodating groove.
As a further improvement, a plurality of holes are respectively distributed on two sides of the tooth containing groove.
As a further improvement, the elastic metal strip is wrapped by a silica gel outer sleeve.
The utility model has simple structure and convenient use, is suitable for the animal experiments of rodent of different types, can fix the head and teeth of the rodent in operation, effectively prevents experimenters from being bitten by the experimental animal, is safe and reliable, and does not cause damage to the experimental animal.

Detailed Description
To explain the technical contents, structural features, attained objects and effects of the present invention in detail, the following embodiments are exemplified and the detailed description is given with reference to the accompanying drawings.
Example 1
As shown in fig. 1, the application discloses a device for preventing rodent from biting, including elastic metal strip 1 with a plurality of holes and elastic cloth strip 2 matched with the elastic metal strip, elastic cloth strip 2 is located on one side of elastic metal strip 1, the interval between two adjacent holes is greater than 3 mm, and two ends of elastic cloth strip 2 respectively penetrate out of two different holes 1A and 1B on elastic metal strip 1.
The elastic metal strip can be made of an elastic metal (such as titanium alloy) sheet with a rectangular cross section and can be bent into a ring under the action of external force. When the device is used, the head of a rodent (such as a rat) for experiment is placed in a gap between the elastic metal strip and the elastic cloth belt, then the elastic cloth belt is tightened, and two ends of the elastic cloth belt are knotted and fixed at the other side of the elastic metal strip. The elastic metal strip has toughness and can support the neck of a rodent, and the elastic cloth belt has a good binding effect on the head of the rodent. The animal after binding can be placed on an experimental operating plane such as an anatomical plate.
Example 2
As shown in fig. 2, the present embodiment is different from the above embodiments in that the tooth receiving slot 3 shown in fig. 3 is disposed in the middle of the elastic metal strip 1, the opening of the tooth receiving slot 3 is disposed on one side of the elastic metal strip 1 close to the elastic cloth tape 2, and the included angle between the extending direction of the end of the tooth receiving slot 3 and the plane of the elastic metal strip 1 is smaller than 90 degrees. Meanwhile, the inner wall of the tooth containing groove 3 is provided with a sawtooth-shaped bulge 3a, a flat tubular cavity 3b is arranged in the tooth containing groove, and a plurality of holes are respectively distributed at two sides of the tooth containing groove 3.
Because the extension direction of the tooth containing grooves is consistent with the growth direction of the teeth of the rodent, and the saw-toothed protrusions in the tooth containing grooves ensure that the teeth of the rodent can be arranged in the tooth containing grooves. Because the heads of different kinds of rodents have different sizes, the head circumference of rat is greater than the head circumference of mouse, can pass through two holes at different intervals with the both ends of elastic strap in different embodiments, can be according to different head circumference adjustment.
In further embodiments of the present application, the resilient metal strip 1 is wrapped by a silicone jacket (not shown in the drawings). The silica gel coat is soft and elastic, and can relieve discomfort of experimental animals caused by oral cavity extrusion.
Referring to fig. 4, the application is used as follows:
1. taking a rat (or other rodent) for experiment, and preparing a device for preventing rodent bite injury, which is provided by the utility model;
2. paving an elastic metal strip of the device for preventing rodent from being bitten, and enabling two ends of an elastic cloth belt matched with the elastic metal strip to penetrate through two open holes with certain intervals;
3. opening a gap between the elastic metal strip and the elastic cloth strip, and placing the head of the rat in the gap;
4. the skin behind the neck of the rat is grasped by one hand, and the head position of the rat is adjusted, so that the front teeth of the rat are placed in the tooth containing grooves and are clamped by the tooth containing grooves;
5. the other hand was used to grasp the ends of the elastic band and pull it taut, while the mouth of the rat was open and the head and incisors were fully secured by the device.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
