Embodiment

[0032] Such as Figure 1-6 As shown, a mouse tail pulse non-invasive blood pressure rapid measurement device includes a system host, an experiment tray 1 and a mouse cage 31 arranged on the experiment tray 1. The mouse cage 31 is provided with a mouse head holder 32 and a mouse tail holder. The device 33 also includes an adjustment plate 6 arranged on the experiment tray 1, and the adjustment plate 6 is provided with a pulse blocker 9, a tail presser 8, a pulse sensor 7, and a tail puller 10 in sequence. The pulse blocker 9, the tail presser 8, the pulse sensor 7, and the tail puller 10 are sequentially fixed on the adjustment plate 6, and the side of the adjustment plate 6 away from the pulse blocker 9 is provided with a rotating shaft fixing seat 5, and the rotating shaft fixing seat 5 is provided with a rotating shaft 51, and the adjustment plate 6 is provided with a hand screw II 61 on the side close to the pulse blocker 9. By adjusting the adjustment plate 6, that is, adj...

Abstract

The invention discloses a noninvasive rapid blood pressure measurement device for mouse tail pulse. The device comprises a system host, an experimental tray and a mouse cage arranged on an experimental tray. A mouse head fixer and a mouse tail fixer are arranged in the mouse cage, a regulating plate is arranged on the experimental tray, and a pulse blocker, a tail pressing device, a pulse sensor and a tail pulling device are arranged on the regulating plate in turn. The rear end of the regulating plate is fixed on the experimental tray through a rotating shaft, and the lifting of the front endis achieved by turning a hand pin at the front end around a fixing shaft, thereby adjusting the height of the axial center of the pulse blocker and the tail of the mouse to be the same; the tail pulling device can be moved forward and backward, a pressing plate on the tail pulling device can also be moved forward and backward, and the combination of the tail pulling device and the pressing platecan adapt to fixing of tails of different lengths; after the tail is compressed by the tail pulling device, the whole body is pulled back by rolling a rotary knob of the tail end to ensure that the tails are in a flat and tight straight state; finally, the blood pressure of the tail of the mouse is accurately measured by adjusting the height of the tail of the mouse and straightening the tail of the mouse.

Description

technical field [0001] The invention relates to the field of medical experiment equipment, in particular to a non-invasive blood pressure rapid measuring device for mouse tail pulse. Background technique [0002] The mouse tail pulse non-invasive blood pressure measurement system adopts the current international popular tail cuff non-invasive blood pressure measurement principle, and is used for the observation of animal arterial blood pressure in chronic experiments. Animals do not need anesthesia, are non-invasive, and are easy to use. The measurement system consists of two parts, the host computer and the measurement device. The host computer mainly plays the role of control and data analysis, and the measurement device mainly plays the role of execution and data collection. The measuring device is composed of the experimental tray, rat tail pulse blocker, rat tail pulse sensor, and rat cage. Due to the large size difference between rats and mice, the measuring devices ar...
