Technical Field

The application relates to the field of medical appliances, in particular to a detachable multifunctional scraping cupping glass.

Background

The cupping is a traditional Chinese medicine therapy which uses the cupping as a tool and generates negative pressure to adsorb body surfaces through modes of burning fire, exhausting air and the like, and has the functions ‌ of clearing and activating the channels and collaterals, promoting qi and activating blood, relieving swelling and pain and the like. The cupping glass is made of fragile materials such as glass, the cupping glass needs to be taken and put lightly, a plurality of cupping glass needs to be used for one treatment, a doctor needs to adsorb the cupping glass to the body of a patient one by one, each cupping glass needs to be adsorbed for a plurality of seconds, tens of cupping glass needs to take a few minutes, the cupping glass can not stay for the first treatment for more than ten minutes, the cupping glass is easier to suck relatively, the cupping glass can be controlled to be about one second in each cupping glass, and thus, the treatment time of different parts is greatly different. If the cupping glass is hung, the cupping glass is more convenient to take and put, but the cupping glass hung together is easy to shake, a plurality of cupping glass are easy to collide with each other, if a thick buffer structure is arranged outside the cupping glass, the volume of the cupping glass is greatly likely to influence the use, and when the thickness of the buffer structure is lower than 3 mm, the cupping glass is also broken when the strong collision occurs.

The Chinese patent publication No. CN202951008U discloses a cupping device with comprehensive action, because the top end of the cupping is connected with a traction rope which is hung on a crankshaft, the traction rope can produce traction action on the cupping and then human body parts and tissues sucked by the cupping in the rotation process of the crankshaft, so that the parts and tissues are not only sucked by the cupping, but also under the action of traction force, and the action of the cupping is penetrated into the deep layer of the body at the cupping part. The design is in the same place that a plurality of cupping glass hang, and the collision easily takes place when quick travel cupping glass, if set up buffer structure in the cupping glass outside, probably the too big influence cupping glass of volume uses.

The patent of Chinese patent grant bulletin No. CN203123113U, named "novel cupping glass", discloses a novel cupping glass, because the top is connected with an elastic traction rope, and the elastic traction rope can be hung on an external support through a hook, the elastic traction rope can produce traction action on the cupping glass, and then human body parts and tissues sucked by the cupping glass, so that the parts and tissues are subjected to traction force except the suction force of the cupping glass, and the action of the cupping glass is penetrated into the deep layer of the body at the position of the cupping glass. The pulling force can be adjusted by changing the length of the elastic pulling rope, and the pulling force direction can be changed by changing the hanging position of the elastic pulling rope, namely, changing the angle of the elastic pulling rope relative to the human body. The design also has the technical problem that a plurality of cupping glass can be easily collided when being hung together and rapidly moved, and if a buffer structure is arranged on the outer side of the cupping glass, the cupping glass can be greatly influenced in use.
