Description

A convenient cupping device

technical field

The invention belongs to the technical field of medical devices, and in particular relates to a convenient cupping device.

Background technique

Taking the can, also known as pushing the can, is to apply a lubricating medium to the skin or the mouth of the can on the part to be pulled, and then adsorb the can to the part that needs to be pulled, and push it back and forth until the skin of the part to be pulled is ruddy and congested, or even blood stasis, the Cans up. Walking is an operation method in traditional Chinese medicine cupping therapy. It transforms the simple "suction" of cupping into a dynamic "sliding friction", that is, the negative pressure suction of a single tank and the friction during walking are combined. For the combined force, it acts on the epidermis of the human body. By mastering the speed, frequency, density (area) of the tank, and controlling the size, direction, and force point of the resultant force, it is possible to selectively and enhance the strong and weak stimuli of suction and extraction, adjust the qi and blood functions of the body's viscera and meridians, and improve the to prevent disease.

Nowadays, with the gradual improvement of people's awareness of health preservation, cupping has entered the life of the general public. Many people operate it at home. The vacuum gun is connected to the vacuum tank through a long straw. Quantified but achieved back cupping alone. However, due to the special position of the back, it is difficult to operate the tank by itself, and it is difficult to accurately control the suction force of the tank on the leather surface. Therefore, there is an urgent need for a cupping appliance that can facilitate the general public to perform the whole-body cupping operation alone at home, can accurately control the suction force, is easy to operate, and has a low price.

SUMMARY OF THE INVENTION

According to the above deficiencies of the prior art, the present invention provides a convenient cupping device, which can be adsorbed on the skin surface by pressing, and the adsorption strength is quantified, the user can carry out the operation of taking the cup on the back alone, the structure is simple, and the cost is low.

The technical solution adopted by the present invention is to include a tank body assembly and a handle assembly, the tank body assembly includes an upper tank, a middle tank and a lower tank, the lower tank is a plastic cylinder, and the middle tank is a rubber Cylinder, the upper tank is a plastic cylinder with a top seal, the top periphery of the lower tank and the bottom periphery of the middle tank, the top periphery of the middle tank and the bottom periphery of the upper tank are all sealed and fixedly connected, and the upper tank is sealed and fixed. A vertical column is arranged vertically in the center of the outer side of the top, and several positioning cards are arranged horizontally on the column. The inner side of the top of the upper tank is fixedly connected downward with a small cylinder, and the left and right side walls of the lower end of the small cylinder are symmetrically opened. There is a vertical opening, and there are strip shelves running through the vertical opening left and right, the left and right ends of the strip shelf are fixedly connected to the inner side wall of the lower tank, and a compression spring is arranged inside the small cylinder, so The bottom of the compression spring is fixedly connected to the top of the strip shelf, the handle assembly includes a U-shaped left handle and a U-shaped right handle, the middle of the front and rear outer walls of the lower tank is respectively provided with a fixing seat, and the left handle spans It is placed on the front and rear sides of the tank assembly, and the tails of the two arms are respectively connected to the left ends of the two fixed seats. The longitudinal section in the front-rear direction is centrally symmetrical, the horizontal bar of the right handle is movably connected to the horizontal bar of the left handle, and the upright column is arranged between the two horizontal bars.

(1) Principle of negative pressure process:

The invention integrates the easy-to-operate features of the silicone tank. The middle tank is made of rubber, which can be deformed. When the tank body is buckled on the human skin surface, it is only necessary to press the top of the upper tank, the compression spring is compressed, the shape of the rubber is changed, and the upper tank and the lower tank are changed. The distance between them decreases, and the space in the tank becomes smaller. When the hand is released, the elastic force of the compression spring keeps the top of the upper tank away from the strip shelf, that is, the upper tank and the lower tank are far away, and negative pressure is formed in the tank.

(2) The principle of suction quantification:

The positioning card on the column is to quantify the suction force. When the left handle and the right handle are erected and the two horizontal bars are connected together, the vertical column is located between the two horizontal bars, because the bottom of the two horizontal bars is fixed with the lower tank. The column is fixed to the upper tank, and the moving distance of the column relative to the two cross bars can be limited by the positioning card, so the distance between the upper tank and the lower tank is also limited, that is, the volume of the gas squeezed out in the tank, which can further limit the distance between the upper tank and the lower tank. The size of the suction force, thereby realizing the quantification of the suction force.

(3) How to use the tank:

The surface of the body is coated with a lubricating medium, and after the quantitative suction of the tank is adsorbed on the surface of the skin to be cupped, separate the horizontal bar of the left handle and the horizontal bar of the right handle, hold the horizontal bars on both sides with both hands, and push the tank body on the body. The watch slides to carry out the tank removal operation. Because the arms of the left and right handles are extended, the distance between the user's hand and the tank can be extended, and the operation of the tank removal operation on the back can also be realized.

The opposite sides of the horizontal bar of the left handle and the horizontal bar of the right handle are protruded and provided with mutually matching magnets.

The magnets attract each other to realize the movable connection between the horizontal bar of the left handle and the horizontal bar of the right handle.

The magnets are respectively arranged at the front and rear ends of each horizontal bar, and the closest distance between the horizontal bar of the left handle and the horizontal bar of the right handle is greater than the outer diameter of the cross section of the column.

The two crossbars are attracted and fixed together by magnets, and a space is formed between the front and rear magnets of the crossbar (that is, the middle end of the crossbar), which is used for the passage of the column, and the column can move up and down in this space.

The positioning card includes a positioning ring and a positioning rod fixed on the outer side wall of the positioning ring and along the radial direction of the positioning ring. The diameter and the outer diameter of the positioning ring are smaller than the length of the positioning rod. Four circular grooves are arranged side by side on the outer side wall of the upright column from top to bottom, and the positioning ring is rotated and arranged in the circular groove. And it fits well with circular grooves.

The process of using the positioning card:

There are a total of four positioning cards, one is set in each circular groove, the inner diameter of the positioning ring is well matched with the outer diameter of the circular groove, so that the circular groove needs to be rotated by external force. . When the horizontal bar of the left handle and the horizontal bar of the right handle are attracted to each other by a magnet, if the positioning rod is moved to be parallel to the horizontal bar, the distance between the two horizontal bars allows the positioning card to move up and down. When the position is perpendicular to the crossbar, the positioning card cannot pass between the two crossbars. When the cupping needs to be sucked lightly, the positioning rod of the bottom positioning card can be moved to be perpendicular to the horizontal rod, and the two horizontal rods are attracted together by a magnet. At this time, the positioning card is located above the horizontal rod, and the can is placed After the watch, press down on the upper tank, when the bottom positioning rod moves to the top of the horizontal rod, it is blocked by the horizontal rod, and the column cannot continue to move down. The vertical distance of the rod. If you want to re-suck, you can turn the top positioning rod to be perpendicular to the horizontal rod, and the other three positioning rods are in the parallel position of the horizontal rod. All positioning rods move downward through the gap between the two horizontal rods, until the top positioning rod is blocked by the horizontal rod and the column can no longer move downwards, then release the pressure on the upper tank, and the upper tank goes down to the tank. The moving distance is the distance from the uppermost positioning card in the initial position to the top of the crossbar. At this time, the gas in the tank is squeezed out the most, and the negative pressure is the largest in the tank after letting go, that is, the suction is the largest.

Four positioning cards, set four different suction power. Moreover, the position of the positioning rod is set according to the required force. During the operation, there is no need to observe the pressing force, which can be easily and accurately quantified, especially the back operation alone, which is more convenient.

The bottom of the small cylinder is located below the strip shelf.

In this way, the strip-shaped shelf is always located inside the vertical opening, and there is no accident that the strip-shaped shelf cannot be aligned and entered into the interior of the vertical opening after being separated from the small cylinder.

Both the lower tank and the upper tank are made of medical resin-polycarbonate material.

This material is non-toxic, odorless, non-irritating, durable, and resistant to falling.

The top of the upright is set as a handle. The canning press can be performed by pressing the handle.

The arm end of the left handle and the arm end of the right handle are both set as telescopic rods, and fastening bolts are provided on the telescopic rods.

Both the left handle and the right handle can extend the arm, so when the back tank operation is performed alone, loosen the fastening bolt to extend the arm, so that the operation is more convenient. However, when the can body is adsorbed to the leather watch for the first time, the lengths of the left handle and the right handle are the shortest, and the fastening bolts are in a tightened state.

The present invention has the following beneficial effects: (1) The present invention adopts the combination of rubber and plastic tank body, and utilizes the structural feature that the silicone tank body can be adsorbed on the leather surface by pressing, and the spring cooperates with the rubber to realize the method of forming negative pressure in the tank after pressing. (2) On the basis of convenient operation, the present invention is provided with a handle that is fixedly connected to the lower tank, a column is fixed on the top of the upper tank, and a positioning card is set on the column to quantify the downward displacement of the upper tank, The quantification of suction is achieved through a simple structure; (3) in the present invention, after the tank body is adsorbed on the skin surface, the left and right handles are separated to facilitate the operation of tank removal, and the user can carry out the tank operation on the back by holding the two handles independently The operation is convenient and simple, and the prior art does not have a technical solution with a simple structure that can carry out the operation of the back tank; (4) the present invention is simple in structure, low in cost, and has a good promotion prospect.
