Warm-keeping temperature control and light guiding system for assisting rat tail vein injection

Abstract

The invention relates to a warm-keeping temperature control and light guiding system for assisting rat tail vein injection. The warm-keeping temperature control and light guiding system comprises a warm-keeping temperature control device and a light guiding system device, wherein the warm-keeping temperature control device comprises a light source, a sensor, an infrared ray thermal receiving probe, a photoelectric converter and a negative feedback circuit; the light guiding system device comprises a light guiding pipe shell, a power supply, a red light, a yellow light and a green light; the power supply is arranged inside the light guiding pipe shell; and an arc-shaped clamping slot is formed in the light guiding pipe shell, and the red light, the yellow light and the green light are arranged on the side surface of the arc-shaped clamping slot. The warm-keeping temperature control and light guiding system for assisting the rat tail vein injection has the advantages that the system is designed for solving the problems in the prior art of rat tail venepuncture, the equipment realizes controllable and adjustable heating and warming (the optimum temperature is 35 DEG C) on a rat tail, so that a tail vein is enlarged; the light guiding system can definitely display a tail vein travel path, tail vein display rate and resolution ratio are improved, and puncture is conveniently guided; and the equipment also can be applied to a rat tail venepuncture fixation frame and is used by coordinating related equipment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a rat tail vein injection auxiliary warming temperature control and light guide system. Background technique [0002] Rat is a commonly used model animal in medical research, which can be divided into rats, mice, nude mice and other types according to different experimental requirements. After mouse modeling, tail vein injection is the most commonly used intervention route. The thickness of the rat tail vein is uneven, and the difficulty of injection is different. The success of the rat tail vein injection directly determines the success rate of the model. At present, the success rate of tail vein injection of mice by experienced experimenters is less than 80%. This means that a large proportion of model mice cannot carry out effective experiments, resulting in huge waste and increasing the cost of experiments. [0003] In the prior art, there are the following defects...
