Spreading knife suitable for pain-relieving antiphlogistic ointment

Abstract

The invention discloses a spreading knife suitable for a pain-relieving antiphlogistic ointment. The spreading knife comprises a cutting head and a knife handle. A blade of the cutting head is blunt and has a radian, an elastic steel piece in smooth transition is welded between the cutting head and the knife handle, the outer surfaces of the cutting head, the elastic steel piece and the knife handle are coated with a teflon non-stick coating, the thickness of the teflon non-stick coating is 15-25 [mu]m, and the cutting head, the elastic steel piece and the knife handle are made of stainless steel. The spreading knife not only has rigidity and does not break during ointment stirring, but also has specific elasticity and the radian to evenly spread the ointment. The spreading knife is further convenient to clean, and pollution and even skin infection caused by metamorphism and mold of the residual and adherent ointment can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to a spreading knife suitable for analgesic and anti-inflammatory ointment. Background technique [0002] Analgesic and anti-inflammatory ointment is used to treat various diseases such as neuralgia, muscle pain, sprains, bruises, mild burns, scalds, frostbite and rashes, etc., with remarkable curative effect. The existing products are all in cans or bottles. When using the paste, it is necessary to stir the paste, take out the part and spread it between two layers of gauze, and then wrap and fix it externally. However, there is no special device for stirring and spreading the paste clinically. .

Problems solved by technology

The existing products are all in cans or bottles. When using the paste, it is necessary to stir the paste, take out the part and spread it between two layers of gauze, and then wrap and fix it externally. However, there is no special device for stirring and spreading the paste clinically.

[0003] At present, tongue depressors or similar sheets are mostly used temporarily to stir and spread the ointment clinically. There are the following defects in use: First, the analgesic and anti-inflammatory ointment belongs to ointment, and the lower layer of ointment will appear after a long period of storage Bonding, especially when the temperature is low, the layering and bonding are more obvious. When using it, it needs to be stirred vigorously to make it even. Because the tongue depressor or similar sheet lacks rigidity, it is easy to break; the second is to temporarily take out part of the paste and spread it At the same time, because the tongue depressor or similar sheet is in a long strip shape, although it has certain elasticity but lacks radian, it is inconvenient to spread the paste evenly on the gauze; the third is that it is not easy to clean because the paste is greasy and sticky, and the residual adhesion A small amount of paste on a spatula or similar sheet is prone to spoilage and mildew, and the spatula or similar sheet is always used repeatedly, so it is easy to cause contamination and even skin infection
