Cam type vacuum cupping device

Abstract

A cam type vacuum cupping device comprises a cup body, a piston, a seal ring, a lever, a pin and a spring, wherein the U-shaped cup body is made of transparent glass or polypropylene, a round opening is downward, a boss is arranged at the upper end of the cup body, a flat hole is formed in the center of the upper end of the cup body, the piston equipped with the spring is inserted in the cup body in a gliding manner from bottom to top, the piston is integrated with a piston rod at the upper part of the piston, the cross section of the piston rod is adaptive to the flat hole, the piston rod penetrates out from the flat hole in the upper end of the cup body, the piston rod in the cup body is sleeved with the spring, a small hole is formed in the upper part of the piston rod, the pin is mounted in the small hole and hinges the piston rod to the left end of the lever, and the lower part of the left side of the lever is formed in a cam shape. The cam type vacuum cupping device has the benefits as follows: the device is convenient to use and simple in structure, an operator can adjust the magnitude of the negative pressure in the cup at any time according to the condition of a patient, and skin burning or scalding in a traditional cupping use process is avoided.

Description

technical field [0001] The invention relates to a cupping device, in particular to a cam-type vacuum cupping device, which is mainly used for cupping treatment. Background technique [0002] Cupping therapy, which is one of the medical heritage of the motherland, is also called the angle method in ancient books. It has a long history of folk use in my country. The traditional treatment method is to burn alcohol cotton balls in the tank to consume the oxygen in the tank, so that the gas in the tank forms a negative pressure, and then the cupping is adsorbed on the epidermis of the acupuncture points, so that the local superficial tissue is congested and the local blood vessels are dilated. , the blood circulation is accelerated, thereby clearing the meridians, promoting the circulation of qi and promoting blood circulation, so that the functions of the internal organs can be adjusted, and the purpose of preventing and curing diseases can be achieved. The disadvantage of tra...

Problems solved by technology

Most of the cupping devices currently on the market are inconvenient to use or have too complicated structures. Some cupping devices also need to be equipped with special vacuum equipment, resulting in high cost of use and cumbersome operation process; During the process, the piston, the main part of the cupping device, not only moves up and down, but also rotates, which makes the fabrication more laborious.
