Abstract

Negative-pressure suction cups in the market have common characteristics that the cup bodies are round bases, have small volumes, are made of a single material, and realize sealing by mean of the contact of a cup opening and skin of human body, so the cup bodies can not be made too big and too heavy, can only execute negative pressure cupping on a local part of the skin surface of the human body respectively, can not cup within a large area of the human body, and can hardly meet the requirements of people to cup on a plurality of uneven parts, particularly the surface of the skin on hands, feet and limbs of the human body. The invention provides a non-skin bearing negative-pressure suction cup, which belongs to a medical appliance. The non-skin bearing negative-pressure suction cup consists of a main cup body 1, a connecting gum cover 2, an accessory cup body 3, a sealed gum cover 4 and an exhaust device 6, and is characterized in that the cup body of the negative-pressure suction cup consists of the main cup body 1 and the accessory cup body 3, the main tank body 1 can receive hands, feet and other parts of the skin of the human body, and the weight of the negative-pressure suction cup is not born by the skin of the human body.

Description

Non-skin load bearing negative-pressure suction cup

Technical field

The invention belongs to medical apparatus and instruments.

Background technology

Various negative-pressure suction cups are arranged in the market, with regard to material, have bamboo, pottery, glass, rubber, plastics or the like, with regard to shape and structure, their structure is identical with form basically, their common feature be tank body based on round, volume is less, material is single, relies on a jar mouth to contact with human body skin and realizes sealing.Because human body skin and the part that suction cup jar mouth contacts should play sealing, play the supporting role of tank body weight again, so tank body can not be done too greatly, weight can not be too heavy; Owing to above reason, the skin area of accepting suction function in the existing suction cup tank body is less, can only implement the negative pressure cup in the part on human body skin surface respectively, can not be in human body larger area scope cup; Though various special-shaped suction cups are also arranged, promptly jar mouth is the suction cup of curved shape, but, because everyone the uneven degree of skin surface has nothing in common with each other, the adaptability of existing special-shaped suction cup is poor, be difficult to satisfy the requirement of people to a plurality of uneven positions cup, particularly can not be simultaneously at the most skin surface cup of the hands of human body, foot, extremity.

Summary of the invention

In order to satisfy the requirement of people to a plurality of uneven positions cup, particularly satisfying can be at the most skin surface cup of the hands of human body, foot, extremity, and a kind of negative-pressure suction cup of form is greatly made in the requirement of cup in human body larger area scope.A kind of non-skin load bearing negative-pressure suction cup, belong to medical apparatus and instruments, form by main tank body 1, connection gum cover 2, additional tank body 3, seal rubber sleeve 4 and exhaust apparatus 6, it is characterized in that: the tank body of negative-pressure suction cup is made up of main tank body 1 and additional tank body 3, tank body 1 can hold the other parts on people's hands, foot and human body skin surface, and the weight of negative-pressure suction cup be can't help human body skin supporting.

Because hands, foot even the most skin surface of human body can enter negative-pressure suction cup, can make the negative pressure treatment technology be applied to medical industry widely, further promote the development of big-and-middle-sized negative pressure medical apparatus and instruments, emerging a kind of medical apparatus and instruments.

Describe below in conjunction with accompanying drawing.

Description of drawings

Main tank body 1 is the container of geometry more complicated, is used for holding people's hand, pin or people's limbs Other parts. The tank body of negative-pressure suction cup is made up of main tank body 1 and additional tank body 3, and additional tank body 3 can To be more piece, to satisfy the needs of the different statures of human body. During use, earlier with hand, pin or the people of human body The other parts of body skin are inserted in the seal rubber sleeve 4, make these positions enter additional tank body 3, then again These positions enter in the main tank body 1 again. Between main tank body 1 and the additional tank body 3, and each additional tank body Connected and the realization sealing by rubber connecting sleeve 2 between 3. Rubber connecting sleeve 2 also can be a plurality of. Tank body and people Connected by seal rubber sleeve 4 between the body skin, contacted with seal rubber sleeve 4 by the skin of human body corresponding site, When exhaust apparatus 6 passes through tube connector 7 and steam vent 5, with the Bas Discharged in the tank body, negative-pressure suction cup Form vacuum in the tank body, human body skin is realized sealing with contacting of seal rubber sleeve 4, reaches in the tank body to keep The effect of negative pressure and realization treatment. Because in the use procedure, main tank body be with ground or with other things Body contact, so the weight of negative-pressure suction cup supports without the skin of human body, but by ground or Other object support, therefore, the volume of negative-pressure suction cup can be done greatlyyer.

Exhaust apparatus can be hand gear, also can be the device of automatically controlling.

The specific embodiment

Because the volumetric ratio of negative-pressure suction cup of the present invention is bigger, tank body can adopt pottery, glass, rubber or plastic material, and through the processing and fabricating molding, these all existing processing technology thereofs can be realized; Tank body of the present invention is combined by a plurality of resolution elements, and the connection gum cover 2 by elastomeric material between the separation tank body connects.Adopt seal rubber sleeve 4 sealings of elastomeric material between negative-pressure suction cup tank body of the present invention and the human body skin.Exhaust mode of the present invention has multiple, and existing suction cup realizes that the manual and automaton of negative pressure can adopt.

Claims (3)

1, a kind of non-skin load bearing negative-pressure suction cup is characterized in that: the weight of negative-pressure suction cup is not to be supported by human body skin.

2, by claim 1, the tank body of negative-pressure suction cup is made up of main tank body 1 and additional tank body 3.

3, by claim 1, the tank body of negative-pressure suction cup holds the other parts on people's hands, foot and human body skin surface.
