Description
Technical field
The present invention relates to the field of medical instrument technology, specifically, being a kind of small-sized medical cupping with pressure relief mechanism
Device.
Background technique
Cupping therapy is widely used in clinical medicine field, is a kind of common Chinese traditional treatment method.Also known as cupping jar gas, suction
Cylinder therapy.Using tank as device, using the heating power venting air therein of burning to generate negative pressure, be allowed to be attracted in skin, cause by
The skin extravasated blood phenomenon at position is pulled out, to achieve the purpose that treat disease.But certain human bodies such as joint, denomination etc. are available
It is smaller in the area of cupping, conventional method cupping operation relatively difficult to achieve, and also traditional method needs to generate negative pressure using open fire,
To the more demanding of operator, the case where there is certain risk, be easy to happen scald, and traditional after treating tank side is taken
Formula on the other hand tilts cupping cylinder to one side, and the other hand presses skin, enters air in tank through gap, to separate canister and skin
Skin, complicated operation, if operation is not careful, patient is easily made to generate sense of discomfort.
Chinese patent literature: CN208031585U discloses a kind of Chinese medical suction cup, including tank body, injection tube and connection
Column, the centre below the front and back sides of the tank body, which is embedded in, is bonded with arc slide, and the inside of the tank body offers
Dead level, the inner wall of the tank body offer through-hole, and the tank body upper end is bonded with connector, offers on the connector slotting
Hole, the side wall of the jack are bonded with sealing ring, and the side of the connector offers slot, the bottom end insertion of the injection tube
Into jack, push rod is inserted into the injection tube, the bottom end of the push rod is equipped with rubber stopper, and the top of the push rod is bonded with
Push plate, the top of the injection tube are bonded with clamping plate, and the bottom end of the connecting column side is bonded with inserting column, and the inserting column insertion is inserted
In slot, the side bonds of the connecting column have support plate, and the side bonds of the connecting column have several fixed plates.Patent text
It is simple to offer disclosed suction cup patent structure, reduces time and the operation difficulty of training, but the patent document is not
The products scheme for solving the lesser human body of cupping area is provided, and the patent document is due to injection tube and tank body volume
Gap causes injection tube needs to detach bigger stroke, just can guarantee the negative pressure demand of the bigger tank interior of volume, treats
Afterwards, when taking tank, it is still necessary to tank mode is taken using traditional, operating experience is required, it is careful to need, in order to avoid generate patient
Sense of discomfort.
Chinese patent literature: CN2671552Y discloses a kind of suction cup, and the suction cup is by air exhaust rod, hard plastic canister and rubber
Glue piston three parts composition, air exhaust rod main body are the gusset of two root long orthogonals, and axial equal-height position is equipped with the multiple groups gill on gusset
Shape triangle bayonet, air exhaust rod both ends are respectively equipped with pumping handle and discoid piston mounting base, and hard plastic canister is transparent hollow circle
Cylinder, one end are equipped with end cap, and the square openings that its diagonal line is slightly larger than gusset width are provided on end cap, and the other end is smooth
Tank mouth, rubber piston are thick disk shape, and side is equipped with annular mounting recess, and outer diameter and the inside diameter elastomeric interference of hard plastic canister are matched
It closes, the piston mounting base of air exhaust rod is inserted into hard plastic canister from end cap end, is fitted into the installation groove on rubber piston, patent text
Offering beneficial effect is: structure is simple, easy to carry, operate it is adjustable, service performance is good, and manufacture it is low in cost, can be disposable
It uses, cross-infection can be prevented.But there is no after solution treatment, tradition takes tank mode complicated for operation, there are certain requirements, it may
Will cause the problem of patient's discomfort, and suction cup described in the patent document using square openings end cover structure with it is orthogonal
The cooperation of gusset, serious rotary freedom when limiting its stretching, rotates it slightly, will be blocked, make by square orifice
At inconvenient.
In conclusion need it is a kind of can avoid it is traditional take tank pressure release mode, directly release stress from inside the device, and
Easy to operate, structure is simple, stretches flexibly, and practicability is good, is suitable for the lesser human bodies of cuppings area such as joint, face
The small-sized medical suction cup with pressure relief mechanism.
