Embodiment Construction

[0012] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0013] As shown in the figure, a warming box for dissolving crystallized mannitol is mainly composed of a box body 3 with a glass door 1 and a stainless steel liner 2, an air heating mechanism and a liquid medicine oscillation device. The air heating mechanism includes a fan 4, a heating Element 5, the heating element is fixedly connected on the bracket 3-1 at the bottom of the box body, and the heating element is a far-infrared heating tube or a resistance wire heating tube. The fan is arranged parallel to the heating element and fixedly connected to the side wall of the box. The liquid medicine oscillation device mainly includes a motor 6 with a deceleration mechanism, an eccentric rocker 7, a rocker mechanism and a liquid medicine basket 9. The rocker mechanism is composed of a pair of slides. Road sh...

Abstract

The invention relates to a heating box for solving the crystal mannite, characterized in that it is mainly formed by a box with glass door and container. The invention also comprises an air heater with a fan and a heating element, and a liquid vibrator. The heating element is fixed on the support. The fan is fixed with the side wall of box. The liquid vibrator is mainly formed by a motor with reducing element, an eccentric swing rod, a swing arm and a liquid cage. The swing arm is formed by a track axle, a bearing base and a bearing. The track axle is connected with the bearing base that fixed at two sides of box. The bearing is sliding connected with the track axle. Two side walls of liquid cage are fixed with the bearing. The eccentric swing rod is connected with the back end of liquid cage. The motor is connected with the side wall of xo. The output axle of motor is connected with the eccentric swing rod. The invention has the advantages in the combination between heating and vibrating.

Description

technical field [0001] The invention belongs to a heating device for melting crystalline medicine, in particular to a heating box capable of rapidly dissolving crystalline mannitol. Background technique [0002] Pharmaceutical injection grade mannitol is a white crystalline powder with low sweetness. , It has been widely used clinically. However, the crystallization of mannitol injection has brought a lot of inconvenience to medical and nursing users: (1) when stored at room temperature, especially when the room temperature is lower than 15°C, due to its supersaturation, the solubility is reduced and crystals are easily precipitated. It cannot be used immediately, and the crystals need to be dissolved before intravenous injection. (2) In clinical application, in order to exert its dehydrating and diuretic effect, mannitol injection must be infused rapidly intravenously, but due to factors such as hypertonicity and particles of the drug, unpreheated mannitol injection must ...
