Problems solved by technology

[0004] However, due to the different operators, it is not easy to grasp the negative pressure value in the tank for this kind of structure. Excessive negative pressure may cause damage to the skin, increase the pain of the patient, and even produce tension blisters, while the negative pressure value is too small to treat And the effect is not good
Moreover, for different patients and different conditions, different negative pressure values ​​should be used to achieve good therapeutic effects. The negative pressure value in the existing cupping tank cannot be standardized and controlled, so the best therapeutic effect cannot be achieved.
In addition, the air valve of the existing manual vacuum cupping is at the top, which is often encountered when covering clothes, which can easily lead to gas leakage
In addition, when the cupping jar is removed from the body surface, due to the negative pressure inside the cupping jar, it will cause tearing and pain on the body surface

Abstract

The invention discloses a cupping jar provided with a negative pressure compensation cavity, and belongs to the field of medical apparatuses. The cupping jar is characterized by comprising a jar body,a valve, a piston and a piston rod; the valve is located in the middle of the jar body, a horizontal hole is formed in the middle of the valve, and a first spring, a cylinder, a fourth spring, a second threaded spring and a fifth spring are arranged in the horizontal hole from back to front in sequence; a center hole is formed in the axis of the cylinder, and a second spring, a first cylinder, athird spring and a first threaded cylinder are arranged in the center hole from back to front in sequence; a rotary button is arranged at the front portion of the horizontal hole. Compared with the prior art, the cupping jar has the advantage that the pressure inside the cupping jar is constant and adjustable.

Description

technical field [0001] The invention relates to a medical device, in particular to a cupping tank with a negative pressure compensation cavity. Background technique [0002] Cupping is a common treatment device in traditional Chinese medicine. Its principle is to use methods such as burning fire and pumping air to generate negative pressure, so that it can be adsorbed on the body surface, causing local blood stasis, so as to dredge the meridian and activate collaterals, promote qi and blood circulation, reduce swelling and relieve pain. , expelling wind and cold etc. effect. Non-open flame cupping is widely praised by doctors and patients because of its safety and easy operation. [0003] The current non-open flame cupping devices are mostly composed of vacuum guns, pots, and connecting pipes, and the cupping effect is realized by using air pumping to form a vacuum negative pressure state. The operation procedure is to connect the vacuum muzzle and the piston on the top of...
