Background
The correct application of the traditional scraping plate requires that a user has certain medical knowledge and can correctly master certain force, so that the angle between the scraping plate and the surface of stressed skin and the degree of fit with the skin are kept. In daily life, people usually have difficulty in mastering the requirements when using the scraping plate to treat diseases, and the force is often applied incorrectly and the angle is wrong, so that the people can not take the scraping plate in the scraping process, or the scraping plate is improperly attached to the skin to cause skin injury. The common scraping plate has simple structure, but has certain requirements on the technique of users and is difficult to be widely popularized. Different people have different tolerance degrees on the scraping therapy, and the action force between the scraping therapy device and the skin is properly adjusted according to specific conditions so as to meet the use requirements of different people.
The prior art also discloses a meridian massage negative pressure conditioning cylinder with an authorized bulletin number of CN204246553U and an electric scraping device with an authorized bulletin number of CN203507076U, which all try to improve the use convenience of scraping by hollow negative pressure, but actually, the convenience and reliability in the operation and use process are still difficult to ensure, and the problems of strong use force and great angle control difficulty of scraping cannot be solved under the negative pressure condition.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and solve the problems of the application force, angle and the difficulty in mastering the skin fitting degree of the scraping device.
In order to achieve the purpose of the utility model, the utility model provides a portable adjustable negative pressure scraping device, which comprises a hollow sleeve with a smooth inner wall, wherein one end of the sleeve is a tangent plane, the tangent plane and the central axis of the sleeve form an included angle of 60 degrees, the other end of the sleeve is provided with a sealing plate, the center of the sealing plate is provided with a threaded hole, and a stud moving back and forth along the sleeve axis is screwed in the threaded hole; and one end of the stud in the sleeve is provided with a piston tightly attached to the inner wall of the sleeve, and the other end of the stud outside the sleeve is provided with a rotating handle.
The tangent plane referred to here means that the plane of the end face of the sleeve is at a certain angle with the axis of the sleeve, and the included angle is 60 degrees at the position which is most suitable for scraping and applying force. The sealing plate is a structure which is stably fixed at the other end of the sleeve, and the relative distance between the sleeve and the stud can be ensured. The extension direction of the threaded hole is parallel to the axis of the sleeve. The piston is tightly attached to the inner wall of the sleeve, namely the piston isolates the inner spaces of the sleeves on two sides of the piston from each other, so that the air tightness between the inner spaces of the sleeves on two sides is realized.
Preferably, one end edge opening part of the sleeve is arc-shaped.
The arc-shaped edge part refers to smooth edge, so that an outer convex angle which can scratch skin is avoided from being generated on the edge of the sleeve.
Preferably, an annular rubber sleeve made of skin-friendly materials is arranged at the edge opening of one end of the sleeve.
The skin-friendly material referred to here is a medical conventional material, and generally light medical silica gel can be adopted. The annular silica gel sleeve is sleeved on the annular bead at one end of the sleeve.
Preferably, a ball-head-shaped grab handle is further fixed to the other end of the sleeve, and a blind hole for accommodating the rotary handle is formed in one side, facing the sleeve, of the grab handle.
The fastening referred to herein may be in the form of a cantilever snap, a loop snap, a threaded connection, a hook and loop fastener, an adhesive, etc., as is conventional in industrial design, and is one of the connection configurations that are conventionally known to those skilled in the art.
Preferably, a graduated scale is arranged on the side face of the stud along the axial direction.
When the sleeve is transparent, the graduated scale is crossed with the sealing plate at the other end of the sleeve, so that a user can read the degree.
Preferably, the side wall of the sleeve close to the other end is provided with an opening for observing the graduated scale.
If the sleeve is not transparent, the sleeve is provided with a hole for reading the scale number.
The sleeve is herein referred to as being positioned adjacent the other end, away from the end that is adjacent the skin, as opposed to the end of the sleeve that is adjacent the end (where a vacuum is to be created).
By rotating the rotary handle, the piston is moved in the sleeve, so that a negative pressure is formed at a position of the sleeve near one end. The angle through the cut surface guides the sleeve so that the axis forms an angle of 60 degrees with the skin in use.
The edge opening part at one end of the sleeve is provided with an annular rubber sleeve or an arc-shaped edge opening, so that the injury to a human body during scraping is avoided.
The design of the ball-head-shaped grab handle accords with the palm structure of a scraping operator, the contact with the rotating handle is avoided when the device is used, and the operation comfort level is improved.
The graduated scale cooperates with transparent sleeve or the supporting trompil of sleeve for the degree that the negative pressure was adjusted can demonstrate directly perceivedly, makes things convenient for operating personnel to adjust.
The beneficial effects of the utility model are that replace traditional popular treatment for sunstroke by scraping the board hard with the negative pressure, have the characteristics of walking jar popular treatment for sunstroke by scraping the patient's neck, the dynamics of standardizing the use simultaneously constitutes certain angle with atress skin when using, can make things convenient for the better use of beginner.
