Thin plaster, plaster thinning making method and apparatus

Abstract

This invention relates to thin black plaster comprising back-up material layer and plaster layer adhered on the back-up material layer. The black plaster thickness is 0.1-0.9mm, and its processing steps contains: 1) Process boiled plaster into plaster blank; 2) heating compress the plaster blank to thin piece whose thickness maintains between 0.1-0.9mm; 3) Cut the molded thin piece to some shape and package to obtain finished product. The thin black plaster equipment comprises delivery mechanism, at the front end of the delivery mechanism a temperature controlling and piece compressing device is arranged for heating and compress the plaster stuff; behind the temperature controlling and piece compressing device, a blank shaping device is arranged for strike the lamellar plaster stuff into wafer shape; a heating and compressing device is arranged behind the blank shaping device for compressing the plaster blank into flakes. The black plaster can be directly pasted on affected part without heating and can be pasted for many times. The shaping machine has simple structure and is convenient to handle; it achieves mechanization continuous production of black plaster molding.

Description

(1) Technical field: [0001] The invention relates to a traditional Chinese medicinal plaster, a thin black plaster; the invention also relates to a thin preparation method of black plaster and a production equipment specially designed for the method. (2) Background technology: [0002] Most of the existing drugs are in oral dosage form. Oral drugs are digested by the stomach, metabolized by the liver, and then absorbed by the small intestine. However, after the drug is detoxified by the liver and destroyed by gastric acid and digestive enzymes, the efficacy of the drug is greatly reduced; and some oral drugs can cause greater irritation to the stomach and are not easy to take by patients with gastric diseases; certain components of some drugs accumulate in It is not easy to be discharged from the body, and long-term medication can cause damage to human health. According to relevant reports, the American medical community believes that in the next 10-15 years, one third of the exi...

AI Technical Summary

Problems solved by technology

Traditional black plasters are operated manually or semi-mechanically, with low efficiency and high processing costs. Because a large amount of harmful gas is discharged during the production process, it has great damage to the health of the staff.

In addition, because the black plaster has a very strong viscosity and tends to harden and become brittle when the temperature is low, it is difficult to spread the plaster layer evenly and thinly with the traditional method.

Therefore, the existing black ointment is larger, thicker and heavier, and its weight is generally between 10-30 grams. Such a heavy plaster is not only inconvenient to carry, but also greatly increases the cost of the plaster, especially the plaster that uses famous and precious medicinal materials. , the cost is higher, and it also causes a waste of drug resources

In order to save money under the premise of ensuring the effective efficacy of the medicine, the traditional method is to use the black plaster repeatedly, which does not conform to the hygiene concept of modern people. Modern people generally use it once and stick it for 1 to 2 days. Discard after that, no more than 5 days at most, and for the traditional, big and thick plaster, a large part of the plaster is still unused after 5 days of use, so it is discarded, which greatly wastes limited medicinal material resources. On the one hand, because the existing black plaster must be heated to soften it before each use, this repeated heating will inevitably lose a large amount of volatile components in the plaster, causing the efficacy to weaken

And because the traditional technology is difficult to control the weight of the plaster, so the weight error between each piece of plaster is relatively large, which does not meet the standardization concept of modern medicine, and the existing black plaster must be heated before each use, which is very inconvenient to use

These shortcomings make modern consumers less and less willing to use black plaster, so the traditional black plaster is currently being replaced by rubber plaster

Rubber plasters are mainly made of rubber, polyisobutylene and other highly adhesive substances mixed with traditional Chinese medicine extracts. This type of plaster is light and thin, and has good sticking performance. When it is peeled off from the skin, it will not pollute the skin plaster, but the skin is prone to erythema, mild swelling, and skin allergies. The greater the adhesion of the rubber plaster, the easier it is to cause this inflammation; and the air permeability of the rubber plaster is poor, and the skin is airtight after application. Moisture permeability makes the outermost stratum corneum of the skin surface very easy to be stimulated to cause keratin hyperplasia, and then the sweat glands are blocked, hindering the excretion of sweat; sweat retention causes the skin to soak and soften, making the skin white and soft. It also makes the skin tissue a good culture medium with appropriate temperature and humidity. Microorganisms such as bacteria and fungi are easy to multiply on the skin surface, causing infection and eczema of sweat ducts and follicles; secondly, the rubber plaster has less drug content and faster drug release. , the sustained release time of the drug is generally 12 hours, and the curative effect cannot be achieved
