Three-dimensional vacuum cupping device

Abstract

The invention discloses a three-dimensional vacuum cupping device, and aims at providing a three-dimensional cupping device having a mutually cooperative structure, being capable of practical and operating, ensuring that limbs enter and exit a housing and a sealing ring without limit and abrasion, can realize reliable vacuum sealing to truncus and limbs, being convenient for use and enabling the easily-damaged sealing ring to be durable. The three-dimensional vacuum cupping device comprises a shell, a loop sealing ring, an exhaust nozzle, a soft tube and a vacuum pump, wherein the inner side of the loop sealing ring on the outer side of the port of the shell is provided with a caliber-variable support ring. The three-dimensional vacuum cupping device is suitable for treating rare and stubborn diseases such as muscularconstricture of limb joints, finger stiffness, limb cold, numbness of extremities, amyotrophy, diabetic foot, elbow arm pain and curl, capillary collapse, blood vessel disappearance and the like, and obtains a special and remarkable treatment effect which is not reported in the traditional cupping device. The treatment and the physical therapy health care function on other diseases are waiting for further experimenting and developing.

Description

technical field [0001] The invention relates to a cupping type physiotherapy device, in particular to a three-dimensional vacuum cupping appliance which mainly utilizes the principle of negative pressure to treat human diseases. Background technique [0002] In ancient times, China had already invented the negative pressure cupping device. Since the Zhou Dynasty (approximately 11th century BC ~ 771 BC) officially became popular, it has been about 3,000 years ago. In the early Chinese medical book "Fifty-two Disease Prescriptions", which was written in the Spring and Autumn and Warring States Period (approximately 770 BC to 221 BC), there are already records about the treatment of diseases with horn method. From (beast) horn jars, bamboo jars, hardwood jars, clay jars, porcelain jars, copper and iron jars to glass jars, transparent plastic jars, and elastic rubber jars, new inventions of the same kind have appeared from time to time over the past two thousand years. As a he...

Problems solved by technology

The first problem with this feature is that it is cumbersome, and the sealing ring must be inflated before pumping; the second problem is that, with the start of vacuuming, the inflatable sealing ring slips, and the two-way force between negative pressure suction and atmospheric pressure Under this condition, a sudden air leak will occur, causing the vacuum to fail

[0009] ⑤ "China Shixin Patent Announcement No. CN 2096354U, announcement date February 19, 1992, application date 91.7.6, applicant: Northwest Medical Equipment Factory, the First Affiliated Hospital of the Fourth Military Medical University of the Chinese People's Liberation Army, name: Limb Zheng Negative Air Pressure Therapy Device", this patent has an earlier filing date among similar applications; it has more annular skeletons and airbag positioning plates than the annular airbags used in the aforementioned comparative documents, and its sealing stability is improved; the first patent in this application exists The first problem is that the operation is cumbersome, and the airbag must be inflated before pumping air; the second problem is that no matter how small the ring frame is, it is impossible to cling to the limb, so the compression between the ring airbag and the affected limb must leave the ring frame. support, there are still risks of negative pressure suction and air leakage to the vacuum chamber under atmospheric pressure; the third problem is that if the leakage is to be reduced, the airbag must be inflated more and compress the affected limb more tightly, and the skin blood vessels of the affected limb will form serious Medical injury caused by full closed-loop radial compression

[0012] The first problem in the comparison document ⑥ is that the middle part of the movable plate is the affected limb, and the outer end is blocked by the rubber sleeve and the limbs outside the vacuum chamber. It is difficult to adjust the movable plate in the rubber sleeve. If the adjustment is not in place, it still exists. The gap between the rubber sleeve and the limb will still be crushed and cracked, resulting in the failure of the vacuum; the second problem is that the inner diameter of the small end of the sealant rubber sleeve is smaller than the limb to be sealed, and even smaller than the hands and feet, so the limb is not squeezed. It is difficult to get in and out of the rubber sleeve by pressing and pulling, and it is easy to cause abrasions on normal limbs, and it is more difficult to get in and out of the affected limb, especially the injured or sick limb; Uneven and excessive pulling, prone to breakage and cracking, resulting in unusable
