Continuous intravenous administration device for animal blood pressure increasing and reducing tests and administration method thereof

Abstract

The invention discloses a continuous intravenous administration device for animal blood pressure increasing and reducing tests. The device comprises a liquid supplementing bottle, a first three-way pipe, an air filter, a second three-way pipe and a puncture needle; the liquid supplementing bottle, the first three-way pipe, the air filter, the second three-way pipe and the puncture needle are sequentially communicated through a hose; a control switch is arranged on the first three-way pipe, a quantitative liquid supplementing device is inserted into the rest pipe opening of the first three-waypipe, the control switch controls the quantitative liquid supplementing device to be communicated with the liquid supplementing bottle or the air filter, and a quantitative administration device bodyis inserted into the rest pipe opening of the second three-way pipe. The invention provides an administration method of the administration device. On the basis of the administration method of the administration device, administration is conducted through the administration device after gas in the hose, the first three-way pipe, the second three-way pipe and the puncture needle is exhausted. According to the continuous intravenous administration device for the animal blood pressure increasing and reducing tests and the administration method thereof, administration is convenient, and on the premise that administration can be independently completed by one person, accurate administration can be achieved, and the dosage of pushed liquid can be controlled.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to an intravenous continuous drug delivery device and a drug delivery method for an animal blood pressure-lowering test. Background technique [0002] Blood pressure is one of the most commonly used, most important, and most critical monitoring physiological indicators in animal experimental research, and blood pressure is also the main determinant of cardiovascular drug analysis and research. In animal raising and lowering tests, if the drug is not administered properly, it will cause errors in animal blood pressure monitoring. At present, in the blood pressure test of continuous intravenous administration of animals, the continuous intravenous administration is realized through a rough and complicated self-made device under the premise of anesthesia. At present, the problems encountered in the operation are as follows: first, because the device is an elastic rubber t...

AI Technical Summary

Problems solved by technology

The current problems encountered in the operation are as follows: firstly, because the device is an elastic rubber tube, the dose of liquid pushed each time cannot be completely controlled; secondly, when supplementing the drug, the catheter is pierced by random needles, and the catheter will be pierced over time. Overdose, when the drug is withdrawn, the catheter leaks; the third is that when completing the entire drug administration process, two people are required to cooperate, that is, one person acts as an assistant to open the catheter channel, and the other person is responsible for supplementary administration and pushing the drug to complete the raising and lowering of blood pressure in animals.
