Inhalation-anesthesia exposing and monitoring device

Abstract

The invention provides an inhalation-anesthesia exposing and monitoring device, which comprises an oxygen or air-oxygen mixed-gas tank, an inhalation-anesthetic volatilizing tank, carrier-gas pipes, a gas inlet hole, an inhalation-anesthetic exposing box, a gas outlet hole, an anesthetic-gas adsorber used in a loop, a multi-parameter anesthetic-gas monitor, an animal body-temperature maintainer, a line, a line access hole, a dissecting microscope, a constant-temperature heating plate, a small-mouse fixing hole, an invasive arterial blood-pressure monitor, a heat-preserving blanket and an operating table, wherein the oxygen or air-oxygen mixed-gas tank, the inhalation-anesthetic volatilizing tank, the inhalation-anesthetic exposing box and the anesthetic-gas adsorber are connected with the multi-parameter anesthetic-gas monitor through the carrier-gas pipes, and the animal body-temperature maintainer is connected with the heat-preserving blanket. The experiments of a plurality of large / small mice can be simultaneously carried out with sufficient and sensitive heat preservation, real-time monitoring and self-heating, and the breathing conditions of the large / small mice under an anesthetic state are observed at any moment. The inhalation-anesthesia exposing and monitoring device has the advantages of reasonable design, simplicity and convenience in operation and strong controllability and not only has the function of anesthetic-concentration monitoring, but also is provided with an anesthetic absorbing device, so that the inhalation-anesthesia exposing and monitoring device is safe and environmentally friendly.

Description

technical field [0001] The invention belongs to an animal experiment device, and relates to an inhalation anesthesia exposure and monitoring device, which is suitable for temperature monitoring, arterial blood gas and invasive arterial blood pressure monitoring of rats / mice during inhalation anesthesia exposure. Background technique [0002] In the experiment of studying the effects of long-term (>0.5h) exposure of inhaled anesthetics on rats / mice, the problem of exposure devices must be involved. Keep the animal breathing spontaneously and avoid intubation or tracheotomy for mechanical ventilation. The reasons for choosing to keep the animals breathing spontaneously without performing tracheal intubation are mainly as follows: ① Perform tracheal intubation or tracheotomy, increase the experimental operation steps, and prolong the experimental time ② Perform tracheal intubation or tracheotomy, due to the Blood loss, airway secretions, catheter distortion, and inaccurate ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the current commonly used inhalation exposure devices, solve the problems that cannot be solved by the current devices, and provide an inhalation anesthesia exposure and monitoring device. The device consists of an oxygen or air-oxygen mixed gas tank, an inhalation anesthetic volatilization tank, Carrier gas tube, air inlet, inhalation anesthetic exposure box, air outlet, anesthetic gas adsorber used in the circuit, multi-parameter anesthetic gas monitor, animal body temperature maintenance instrument, line, line access hole, dissecting microscope, constant temperature heating plate, small Rat fixation hole, invasive arterial blood pressure monitor, insulation blanket, and operating table. On the lower left side of the inhalation anesthetic exposure box, the mouse fixing hole is opened under the front of the inhalation anesthetic exposure box. The airtight inhalation anesthetic exposure box is placed on the operating table, and the oxygen or air-oxygen mixed gas tank is connected to the inhalation anesthetic through the carrier gas tube. The volatilizer is connected to the inhalation anesthetic exposure box through the air inlet, and the anesthetic gas adsorber and multi-parameter anesthetic gas monitor are used in the circuit to connect to the inhalation anesthetic exposure box through the air outlet. The insulation blanket is connected, and the insulation blanket is placed at the bottom of the anesthetic drug exposure box. The temperature of the insulation blanket is controlled by the animal body temperature maintenance instrument. The constant temperature heating plate is located under the mouse fixing hole, and the dissecting microscope is placed on the operating table, close to the constant temperature heating plate and the mouse fixation. hole, the invasive arterial blood pressure monitor is placed on the operating table, and when invasive arterial blood pressure monitoring is required, it is connected to the artery of the experimental animal (rat / mouse) through the arterial pressure measuring tube
