Embodiment 1

[0023] Production of gavage drug delivery device:

[0024] 1) The production method of the gavage drug delivery device is as follows, but not limited thereto: take a 12cm-long silicone tube of No. 10-16 as the injection hose, use scissors to smooth the edge of the incision at one end, and pass it through a transparent tube with a diameter of 2cm. The organic plastic circular plate is used as a baffle, so that it can slide along the injection hose, and then connected to a 10ml ~ 50ml syringe (including the injection barrel and the propulsion part), that is, the following figure 1 The fish gavage device shown: injection barrel (1), propulsion part (2), baffle (3) and injection hose (4).

[0025] 2) Examples of the manufacturing method of the gavage drug fixing device are as follows, but not limited thereto: Take a solid wood board with a length of 25cm, a width of 15cm, and a thickness of 1.5cm, and open 0.5cm in width, 1.5cm in depth, and 20cm in length on the inside. slots, t...

Embodiment 2

[0027] Take 100 red-fin snappers about 20 cm in length, and use the fish gavage drug delivery device prepared in Example 1 to carry out the gavage experiment.

[0028] 1. Feed preparation for gavage:

[0029] Dissolve the drug in water or a co-solvent and prepare a solution of the required concentration, stir and mix with the fish feed at a ratio of 1: (8-12) to make a liquid food, and let it stand in a refrigerator at 4°C for 3-6 hours.

[0030] 2. Administration by intragastric administration:

[0031] 1) Take out the prepared gavage feed 1 hour in advance. When the temperature is consistent with room temperature, place the injection hose of the gavage applicator in it, slowly pull the propulsion part, and stop when it reaches the required scale.

[0032] 2) Wrap the experimental fish with a wet towel first, place the experimental fish horizontally on one end of the wet towel so that the head of the fish is 1-2 cm above the edge of the towel, then grab the fish body...

Abstract

The invention discloses an intragastric administration device for fish and an administration method. Fish can not be hurt when administration is conducted on the fish through the intragastric administration device for the fish, and measures for protecting safety of an operator are good. The administration method is easy to operate, small in error, wide in applicability and capable of ensuring that administration is fully conducted on the fish. According to the administration method, the requirements for conducting specific administration on small experimental fish in the scientific research process or conducting specific administration on rare aquarium fish in the rare fish cultivation process can be well met.

Description

technical field [0001] The invention relates to a fish gavage drug delivery device and a drug delivery method. Background technique [0002] To prevent and control fish diseases, whether the medication method is appropriate or not plays a decisive role in the control effect. The methods of drug administration for the prevention and treatment of fish diseases include oral administration, splashing in the whole pool, soaking the body in a bath, hanging baskets and bags, injection, local application and indirect administration. The most commonly used methods are the following three: 1. The whole pool splashing method. The efficacy of this method of administration is not affected by the appetite of the farmed animals. As long as the drug is dissolved and sprinkled evenly, all individuals in the pond can be exposed to the drug. Second, the body bath method. This method is often used to prevent fish diseases, and it is one of the effective methods to improve the survival rate o...
