Description

Accurate injection appearance of mouse tail vein

Technical Field

The utility model relates to a toy experiment technique, concretely relates to device of accurate injection of mouse tail vein.

Background

Mouse tail vein annotation is an injection mode which is widely applied in pharmacology and toxicology experiments, and is an indispensable experimental operation in the construction process of a tumor metastasis model. However, the tail vein of the mouse is small, the vascular wall is thin, and the skin surface of the tail of the mouse is covered by hard scales, so the mouse tail vein injection is still an injection mode with higher difficulty and lower success rate at present. Experimenters engaged in tail vein injection of mice usually need to spend a great deal of time and energy to train, so that the success rate of tail vein injection of the mice can be improved to a certain extent by experience, and random errors brought by tail vein injection operation of operators during experiments can inevitably influence experimental results. Most of the traditional mouse tail vein injection instruments are used for simply fixing a mouse fixer on an operation platform, so that a yellow light source irradiates the tail tissue of a mouse, and the tail blood vessel can be clearly observed during injection.

The utility model discloses a mouse tail injection vein imaging appearance that chinese utility model patent application publication number is CN201820327709.6, essential element include regulator, mouse fixer, main body machine case, fixed slot, tail indent, handle, digital moving platform and pressure tail pole, and wherein the main body machine case is provided with the regulator, and the mouse fixer sets up in case top middle part, and mouse fixer front end is pegged graft with the fixed slot, and the fixed slot front side is provided with the tail indent, can realize fixing to mouse tail.

However, the mouse tail injection vein imaging instrument has the following obvious disadvantages:

1. because the operation range of the tail operation of the mouse is not wide, the moving platform in the instrument has little significance in practical use;

2. the position of the mouse fixer in the main case is fixed, so that the requirement for moving the relative position of the animal in the actual operation process cannot be met;

3. because of the lack of a visual imaging device and a heating light source, an operator still needs to train for a long time to complete effective tail vein injection operation and the success rate is improved extremely limitedly, the mouse tail vein injection imaging instrument does not fundamentally solve the core difficulty of mouse tail vein injection.

SUMMERY OF THE UTILITY MODEL

To the not enough that current mouse tail intravenous route solution exists, the utility model aims to provide an easy operation can show the mouse tail intravenous route scheme that improves the injection success rate, realizes that operating personnel need not to accomplish the purpose of mouse tail intravenous route through long-term training just easily, has greatly reduced because of the random error that experimental operation introduced, improves the accuracy of animal experiment. In order to achieve the above purpose, the present invention is realized by the following technical solution: the mouse tail vein precise injection instrument comprises an electric wire, a current regulator, a power supply button, a mouse fixer, a fixer regulating sliding groove, a main case, a mouse tail fixing groove, a heating light source, a snake-shaped mobile phone support, a digital magnifier and a fixing support thereof, wherein the current regulator, the power supply switch and the electric wire are arranged on a left side panel of the main case, the mouse fixer is arranged in the middle of an upper panel of the main case, the mouse tail fixing groove is arranged in front of the mouse fixer, the digital magnifier support is arranged at the left front part of the upper panel, and the snake-shaped mobile phone support is arranged at the right side of the main case to be matched with an external mobile phone for imaging.

Preferably, the mouse tail fixing groove is made of rubber, and a controllable light source for heating the mouse tail is arranged in the middle of the mouse tail fixing groove;

preferably, the digital magnifier is a high-definition digital magnifier with a built-in WIFI chip.

The utility model discloses the advantage effect of scheme does: the instrument structure can highly adapt to mouse tail vein injection actual operation sight, can show and improve the success rate that does not implement mouse tail vein injection by traditional tail vein training injection operating personnel, and the practicality is extremely strong.
