Description

Avoid transportation save set of mannitol crystallization

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a transportation and storage device for avoiding crystallization of mannitol.

Background

Mannitol is an isomer of sorbitol, and hydroxyl groups on the second carbon atom of two alcohol substances are oriented differently, so that the mannitol is easily soluble in water, is a white transparent solid and has sweet taste similar to sucrose; and mannitol is a basic national drug, has been collected and loaded in the Chinese pharmacopoeia, belongs to mannitol as a dehydrated drug, and has wide clinical application. The 20% mannitol injection is a hypertonic dehydrating agent commonly used in clinic, has the effects of reducing intracranial pressure, intraocular pressure and the like, and is commonly used for encephaledema, excretion of excess accumulation of medicines, early renal failure, preoperative preparation of intraocular and intestinal tract operations and the like caused by various reasons. The mannitol is a polyol, has the solubility of 1:5.5 in water, is a supersaturated solution in 20% and 25%, and is easy to generate mannitol particles and even separate out crystals at room temperature of below 15 ℃, so that the mannitol particles are dangerous to cause thrombus or phlebitis. When the temperature is continuously reduced, the crystal is enlarged and takes the shape of large columnar and flocculent crystals. The 20% mannitol injection uses the instruction to point out: 20% mannitol is easy to crystallize when cooled, so the mannitol should be carefully checked before application, if the mannitol is crystallized, the mannitol can be placed in hot water or shaken forcefully, and the mannitol is used after the crystals are completely dissolved; meanwhile, as the mannitol is mostly packaged in a transparent glass bottle or a plastic bottle, a patient can have fear after discovering mannitol crystallization, and doctor-patient contradiction is often caused.

In 1940, smith doctors used mannitol injection clinically to prevent and treat acute renal failure, and with the recognized safety and effectiveness of mannitol in clinical treatment, the mannitol is widely used nowadays for treating cerebral edema, high intraocular pressure, osmotic diuresis, promoting excretion of drugs or toxic and harmful substances, preoperative preparation of patients, and the like.

At present there is a product that has been widely used clinically, and the name is "mannitol heating bag", and this kind of product is mostly the bag form container of heating wire heating, and whole material is mostly composite, and the inner wall is silvery white reflection stratum, and the centre accompanies heater strip and thermal-insulated sponge, and outmost is opaque plastic film, and this kind of product has two drawbacks: (1) temperature cannot be accurately controlled, the temperature of the common infusion solution is 15-35 ℃, such as lower than 15 ℃, which can cause vasospasm of a patient or phlebitis, and if higher than 35 ℃, which can cause denaturation of blood cells, endothelial cells or other proteins in venous blood vessels, is unfavorable for rehabilitation of the patient, so that the accurate control of the temperature of the infusion solution is the first step for ensuring the safety of clinical medication; (2) the mannitol is not beneficial to observing the transfusion condition of a patient in real time, and due to the design defect, the mannitol is generally placed in the mannitol heating bag in a whole bottle, so that the mannitol heating bag needs to be opened for each observation, the workload of medical personnel is increased, and the mood of the patient can fluctuate due to frequent bag opening observation.

The Chinese patent application: CN212424097U discloses a mannitol heating heat preservation storage device. This mannitol heating heat preservation storage device includes: a storage box with a cover, a temperature-controllable electric heating mouse pad and a heat-insulating material; the temperature-controllable electric heating mouse pad is arranged at the bottom or around the storage box with the cover; the thermal insulation material is arranged in the storage box with the cover, the device can heat and insulate mannitol, but the whole structure is too simple, mannitol in the box body cannot be reasonably stored, and the box body type structure is not convenient to take, so that certain defects are caused when the device is used.

Therefore, in summary, there is a need for a transportation and storage system capable of avoiding mannitol crystallization during the whole process of storage, transportation and clinical use, so as to improve the quality of medicine, the safety of patient medication and reduce the contradiction between doctors and patients.
