Description
Technical Field
The utility model relates to a fixing and adjusting device for noninvasive drug administration of mouse trachea.
Background
Tracheal intubation is one of the basic procedures in many animal experiments. The experimental animal mice (including rats and mice) have small physique, small operation space and small functional residual capacity, improper intubation operation usually causes asphyxia and oxygen deficiency due to overlong time or improper operation or improper method, and even die in intubation, thus seriously affecting the smooth progress of scientific research experiments. At present, a simple device is required to be prepared for rat trachea cannula operation in a laboratory for more experiments, and a noninvasive drug delivery process is completed. Typically, these simple devices are made from living goods such as simple plastic, cardboard, wire, etc. Generally, after fixing the anesthetized rat, the lower jaw of the rat is opened, and after exposing the birth door, a catheter is inserted into the trachea.
Under the general condition, this operation needs the cooperation to go on, and because the simplicity of self-control workstation, need artificially cooperate experimental animals' angle, direction etc. may cause the extension of test time, and then influence the reliability of experimental result and even experiment completion degree.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a fixing and adjusting device for noninvasive rat trachea drug administration. The device can be experimental according to experiment needs selection regulation fixing device's direction and angle, through fixed convenient follow-up experiment operation with the experimental animal is fixed effectively to the illumination corollary equipment that can adjust the angle according to the experiment needs is provided, makes trachea cannula process of dosing can be independent, quick, accurate completion. The experimental animal is a mouse, including a rat and a mouse.
The utility model provides a technical scheme that its technical problem adopted is: the trachea cannula drug delivery device comprises a bottom plate (1), a power switch (2), a height-adjustable support (3), an angle-adjustable experimental animal placing plate (5), an angle-adjustable experimental animal placing plate (7), an experimental animal fixing clamp (11), a mouse incisor fixing wire (8), an angle-adjustable and brightness LED illuminating lamp (9). The bottom plate is connected with a power supply, so that the LED illuminating lamp with the adjustable angle and brightness can be conveniently used (9), and the brightness of the lamp can be adjusted through the knob of the power switch (2); the bottom of a thick rod support of the height-adjustable support (3) is fixedly connected with the bottom plate (1) through threads, the height-adjustable support is formed by connecting a thick rod support (3) with a thin rod support (5), the thick rod support (3) and the thin rod support (5) are connected through a rotary knob (4) in a turnbuckle mode and can be adjusted to be telescopic, and then the height of the height-adjustable support is adjusted to be proper; (5) the top of the thin rod support rod is connected and fixed with the experimental animal placing plate (7) through the rotary knob (6) in a turnbuckle mode, the angle between the experimental animal placing plate (7) and the bottom plate (1) can be adjusted through the rotary knob (6) to rotate the screw, the angle of the experimental animal can be conveniently adjusted through experiments, and the optimal trachea cannula angle can be found; (7) the upper part of the experimental animal placing plate is provided with (8) mouse incisor fixing wires for fixing mouse incisors during mouse trachea cannula experiments; the middle part of the experimental animal placing plate is provided with (11) an experimental animal fixing clamp which can be opened or closed to fix the body of the experimental animal.
