A water bath heating and dissolving heat preservation device for mannitol

Abstract

The invention discloses a thermal insulation device for water-bath heating and dissolving of mannitol. The thermal insulation device comprises a heating box and a thermal insulation box, wherein a thermal-protective coating is arranged between the heating box and the thermal insulation box; the heating box and the thermal insulation box comprise box bodies and box covers; box body walls and the box covers structurally comprise housings, thermal insulation layers and water-resisting layers; a heating device is arranged above the thermal insulation layer inside each box body and is connected with a temperature controller; a filter net is arranged inside each box body; a vertical lead rail is also arranged at the inner side of each water-resisting layer; a bump matched with the corresponding lead rail is arranged on the edge of each filter net; a filter net crank is arranged on the outer side of each box body, and controls the corresponding filter net to slide up and down along the corresponding lead rail through a cam device; a heat-conducting coil is also arranged on the bottom of the thermal insulation box; a water inlet and a water outlet of the heat-conducting coil are formed inside the heating box; a miniature temperature control electric pump is arranged at the water inlet section of the heat-conducting coil inside the thermal insulation box, and connected with the temperature controller. The device can be used for heating and constantly keeping warm, the problems that mannitol injection is not easy to inject at low temperature or high temperature are solved, and the thermal insulation device has an energy-saving effect, and is convenient to use, low in manufacturing and use costs, and convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a mannitol water bath heating, dissolving and heat preservation device. Background technique [0002] Mannitol is a national essential drug, which has been included in the "Chinese Pharmacopoeia", and mannitol is classified as a dehydration drug, and it is widely used in clinical practice. 20% Mannitol Injection is a commonly used hypertonic dehydrating agent in clinical practice. It has the functions of reducing intracranial pressure and intraocular pressure. Preoperative preparation for intraocular and intestinal surgery, etc. Because of its definite curative effect and safe effect, it is widely used clinically. However, since mannitol is a polyol with a solubility of 1:5.5 in water, 20% and 25% are both supersaturated solutions. When the room temperature is lower than 15°C It is very easy to produce mannitol particles, or even precipitate crystals, which may cause th...

AI Technical Summary

Problems solved by technology

Put the heated mannitol into the incubator and set the temperature at 35°C~45°C to maintain the dissolved state of mannitol, which solves the problem that the mannitol injection is easy to crystallize when the temperature is too low in clinical use, and the problem that the injection is not suitable for injection when the temperature is too high , saving time and labor; at the same time, the hot water in the heating box can heat the water in the incubator by reflowing in the incubator to keep the temperature in the incubator constant, which is safe and energy-saving; it does not affect the pH value of the drug and can be stored for a long time
