Description

Technical Field

[0001] The utility model relates to the field of rat tail vein drug administration, in particular to a rat tail vein drug administration fixing device with adjustable size. Background Art

[0002] Mouse tail vein injection is a very important technique in animal experiments. However, due to the extremely small size of the mouse tail, it is very demanding on the operator's skill. To reduce the difficulty of operation, the mouse needs to be fixed. There are two main types of existing fixing devices: one is an independent fixed sleeve, which moves with the mouse's twisting, making drug administration more difficult and making it easy for the experimenter to be accidentally injured by the needle during operation; the other is to add a base to the fixed sleeve, which is connected to the fixed sleeve as an integral structure. In this case, the base will limit the fixed sleeve, thereby effectively suppressing the fixed sleeve's freedom of movement. However, this fixed sleeve cannot be adjusted arbitrarily during drug administration, requiring a long time before drug administration, which affects drug administration efficiency. Utility Model Content

[0003] The purpose of the present invention is to solve the problems in the background technology and provide a rat tail vein drug delivery fixation device with adjustable size. The device consists of a split base and a fixed sleeve. Each base can be adapted to fixed sleeves of various specifications, which has higher flexibility in use and improves the efficiency of drug delivery.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A size-adjustable rat tail vein drug delivery fixation device comprises a base and a fixed sleeve detachably mounted on the base, the base being provided with a vacuum suction cup fixed to a desktop, the surface of the base being provided with two baffles parallel to each other and perpendicular to the base, the spacing between the two baffles being greater than the diameter of the fixed sleeve, the fixed sleeve being placed on a base plate between the two baffles, each baffle being provided with a locking screw for limiting the fixed sleeve, a base plate being formed at one end of the fixed sleeve, a limiting groove being machined on the base plate and axially penetrating the fixed sleeve, an extension platform being machined on the base plate outside the limiting groove, a fixing belt being installed on the extension platform, and a detachable sliding plug being fitted inside the fixed sleeve.

[0006] There are multiple fixing sleeves, and the multiple fixing sleeves have different sizes and the same shape.

[0007] The size-adjustable rat tail vein drug delivery fixation device provided by the utility model has the following beneficial effects:

[0008] (1) By providing a split base and a fixing sleeve, the position of the fixing sleeve can be adjusted according to the position of the mouse and then fixed to the base, so that the veins on both sides of the mouse's tail can face the operator, improving the flexibility of fixing the mouse for drug administration, thereby improving the drug administration efficiency;

[0009] (2) By setting a limiting groove and a fixing belt, the mouse's tail can be limited to prevent the mouse's tail from shaking at will, thereby improving the safety of drug administration;

[0010] (3) By providing a plurality of fixing sleeves of different sizes, a fixing sleeve corresponding to the size of the mouse can be selected according to the size of the mouse, thereby ensuring the stability of the fixation and effectively controlling the activity of the mouse.

[0014] Example

[0015] like Figure 1As shown, the size-adjustable rat tail vein drug delivery fixing device provided in this embodiment includes a base 1 and a fixed sleeve 5 detachably mounted on the base 1, the base 1 is provided with a vacuum suction cup 2 fixed to the desktop, there are four vacuum suction cups 2, evenly distributed at the four corners of the base 1, the surface of the base 1 is provided with two baffles 3 parallel to each other and perpendicular to the base 1, the spacing between the two baffles 3 is greater than the diameter of the fixed sleeve 5, the fixed sleeve 5 is placed on the bottom plate 6 between the two baffles 3, each baffle 3 is installed with a locking screw 4 for limiting the fixed sleeve 5, the fixed sleeve 5 is formed with a bottom plate 6 at one end, and a line is processed on the bottom plate 6 that penetrates the fixed sleeve 5 in the axial direction. 5, the limiting groove 7 can allow the mouse tail to extend out of the fixed sleeve 5, so as to facilitate the drug administration of the mouse tail. An extension platform 8 is processed on the bottom plate 6 outside the limiting groove 7, and a fixing belt 9 is installed on the extension platform 8. The fixing belt 9 is used to fix the mouse tail to improve the safety of drug administration. A detachable sliding barrel plug 10 is installed in the fixed sleeve 5, and the sliding barrel plug 10 is used to fix the mouse. The sliding barrel plug 10 has been used in the prior art, so it will not be repeated here. There are multiple fixed sleeves 5, and the multiple fixed sleeves 5 have different sizes and the same shape. Multiple fixed sleeves 5 of different sizes can be selected according to the size of the experimental mouse to select the corresponding size to ensure the stability of fixing the mouse.

[0016] The method of using the utility model is:

[0017] When loading a mouse, hold the fixed sleeve 5 in your hand, take out the sliding plug 10, then lift the mouse's tail, and insert the mouse's tail from the limiting groove 7 into the fixed sleeve 5, so that the mouse enters the fixed sleeve 5. At this time, the mouse's head is facing the end away from the bottom plate 6. Then install the sliding plug 10 on the mouse's head, and then install the sliding plug 10 back into the fixed sleeve 5. Use the sliding plug 10 to fix the mouse, and finally use the fixing belt 9 to fix the mouse's tail on the extension platform 8; then select a convenient position on the experimental table, fix the bottom plate 6 on the experimental table with a suction cup, and then place the fixed sleeve 5 with the mouse between the baffles 3 on the base 1. After adjusting the mouse's dosing position, rotate the locking screw 4 to position the fixed sleeve 5.

[0018] When administering the drug, the drug is administered to one side of the rat's tail vein in the experiment. When the other side of the tail vein is to be injected, the locking screw 4 is loosened, the position of the fixing sleeve 5 is adjusted and then fixed, which can greatly improve the efficiency of drug administration in the rat's tail.

[0019] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modification or replacement based on the technical solution and the concept of the present invention shall be included within the scope of protection of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits descriptions of known components and processing technologies and processes to avoid unnecessary limitations on the present invention.
