Abstract
The utility model relates to a suction cup capable of regulating the suction force, which consists of a cup body, a piston, a piston rod, a sealing ring and a handle, wherein the sealing ring is sheathed on the piston, the piston is positioned in the cup body to be glidingly matched with the cup body, the piston rod is screwed with the top of the cup body, the lower end of the piston rod is fixed on the piston, and the upper end of the piston rod is positioned outside the cup body and is fixed with the handle. The suction cup has the advantages that the operation is convenient and safe, and in addition, the cup body suction force regulation can be carried out according to the bearing ability of patients.
Description
Technical field
This utility model relates to medical apparatus and instruments, exactly is a kind of canister of dialling of scalable suction.
Background technology
Adopting the cupping therapy disease is traditional treatment method of China, and traditional cupping jar need produce suction with burning, inconvenient operation, and also easy fire victim, and also the suction that cupping jar produces can not be regulated according to patient's ability to bear.
Goal of the invention
The purpose of this utility model provides a kind of canister of dialling of scalable suction, makes cupping therapy easy and safe to operate, and can carry out the adjusting of tank body suction according to patient's ability to bear.
Group canister of scalable suction described in the utility model, form by tank body, piston, piston rod, sealing ring and handle, sealing ring is enclosed within on the piston, piston is positioned at tank body and tank body is slidingly matched, piston rod and tank body top spin, its lower end is fixed on the piston, and its upper end is positioned at outside the tank body and is fixed with handle.
In use, tank body lower end (opening) is close to patient skin surface, turning handle then, piston rod is rotated with respect to tank body, because piston rod and tank body top spin, so piston rod will drive piston and move along its axis direction with respect to tank body, make tank body cavity of resorption (chamber that contacts with patient skin surface) produce negative pressure, thereby make tank body be adsorbed on patient skin surface.
This utility model has avoided existing cupping jar to adopt incendiary mode to produce the potential safety hazard that suction brings, so make the treatment of cupping jar fool proof and easy to operate owing to be to make tank body produce negative-pressure sucking by the mode that increases tank body cavity of resorption volume; Because the size of intracavity negative pressure is decided by the stroke of piston under the tank body, and the stroke of piston can be realized by the rotation of handle, so this group canister can carry out the adjusting of tank body suction easily according to patient's ability to bear.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 looks generalized section for the master who dials canister of scalable suction described in the utility model.
The specific embodiment
The canister of dialling of this scalable suction is made up of tank body 2, piston 3, piston rod 4, sealing ring 1 and handle 5, periphery upper edge at piston 3 circumferentially offers the twice cannelure, thereby sealing ring 1 is positioned at this cannelure to be enclosed within on the piston 3, piston 3 is positioned at tank body 2 and is slidingly matched with tank body 2, piston rod 4 is a threaded rod, itself and tank body 2 tops spin, and its lower end is fixed on the piston 3, and its upper end is positioned at outside the tank body 2 and is fixed with handle 5.
