Problems solved by technology

The production of magnesium sulfate wet compress tablets is subject to high requirements for core materials and packaging materials. If there is a problem with the quality of packaging materials, leakage will occur and cause major losses.
In addition, the production equipment belongs to special equipment with high cost and poor maneuverability. During the production process, it is often shut down for maintenance.
But along with the continuous deepening of research, the inventor finds out in practice: magnesium sulfate wet compress sheet is prone to mildew and moisture extravasation in production and storage, is not easy to store for a long time
In addition, since the wet compress is a water-containing product, the whole process of production is difficult to control pollution due to water-containing operations, and the product is heavy, transportation costs and operations are also complicated

Abstract

The invention discloses a preparation and a test method of a magnesium sulfate dried piece. The preparation comprises the steps of taking medical material as a carrier, drying the medical material fully soaked by magnesium sulfate at 60-100 DEG C, and controlling the water in the magnesium sulfate dried piece to be less than or equal to 10%; and controlling the content of MgSO4.7H2O to be 0.25g-0.50g / plus or minus 0.07 per 10 square centimetre of the magnesium sulfate dried piece. When the magnesium sulfate dried piece is applied, the magnesium sulfate dried piece is moistened by water, but no water is dropped (adding 1mL of water per 10 square centimetre). According to the preparation and test method of the magnesium sulfate dried piece, the quality control on the finished magnesium sulfate dried piece is effective, and the precision, the stability and the repeatability of the method are high, the quality of the product can be controlled effectively, and the stability and the consistency of the product quality can be ensured, so that the safety and the effectiveness of the product can be ensured.

Description

technical field [0001] The invention belongs to the field of medical technology, and relates to a medical auxiliary material for the prevention and treatment of swelling and pain caused by edema in local subcutaneous tissue, more specifically, a preparation and detection method of dry magnesium sulfate tablets with anti-inflammatory, swelling-relieving and pain-relieving effects. Background technique [0002] Over the years, non-corrosive and corrosive drugs or solutions have entered the surrounding tissues due to negligence in intravenous infusion, causing exudation and extravasation, resulting in swelling and pain in local subcutaneous tissue. In recent years, the use of chemotherapy drugs by malignant tumor patients often causes superficial phlebitis in different degrees, which brings great pain to the patients. At present, the commonly used method for treating swelling and pain of local subcutaneous tissue is magnesium sulfate aqueous solution and medical phlebitis. The ...
