Description

The wild drawing pen of radiotherapy

The utility model relates to a kind of drawing pen, particularly be the wild drawing pen of a kind of radiotherapy.

At present external radiotherapy mechanism adopts mostly that the disposable irradiation model made from macromolecular material is fixed, labelling or adopt fluorescent material to rule at patient's body surface, need special equipment could reappear sign during radiotherapy, the material that these two kinds of methods are used is all expensive.

Each homemade bamboo let of the scoring tool unit of being that present domestic many decades uses dips in and gets special-purpose skin ink and rule at body surface, and it has the following disadvantages.

1, the bamboo let line can't be satisfied required precision and the thickness inequality that wild markings are established in radiotherapy on the human body curved surface, and straight line is not straight, brings too much error to radiotherapy, make the normal structure radioactive dose too much and/or need the irradiation tissue to leak photograph, thereby influence radiocurable quality control;

2, the self-control bamboo let is diversified in specifications, causes treatment institute to retouch the border range of exposures and repeats, and is coated with when retouching and establishes wild poor repeatability first;

3, nearly all patient all uses several bamboo lets and/or same patient to use same bamboo let line at different parts (as incidence or hypogastric region), has the dermopathic possibility of cross infection inevitably;

4, because patient's body surface thickness inequality, extremely inaesthetic line easily increases patient's psychological burden, is unfavorable for patient's rehabilitation.

In view of above reason, the purpose of this utility model is for but a kind of point, straight line, also trace drawn is provided, setting-out is flexible, accurate, attractive in appearance, health, can avoid cross infection and reduce patient's psychological burden, is beneficial to that the radiotherapy doctor carries, the wild pen of radiotherapy easy to use.

The purpose of this utility model is achieved in that a body in this utility model, at least one on one's body end of pen has a body sleeve pipe, and the handwriting that contains nib places in the body sleeve pipe (referring to Fig. 1).

The ink bundle is arranged, nib and ink Shu Xiangtong (referring to Fig. 1) in the above-mentioned handwriting.

Have on the above-mentioned nib with handwriting in the groove (referring to Fig. 3, Fig. 4) of ink Shu Xiangtong.

An above-mentioned pen body sleeve pipe of an end on one's body is connected by turning cylinder with a body and turns (referring to Fig. 1), can draw straight line, also trace neatly.

An above-mentioned body sleeve pipe is positioned at the nib place cleaning cotton pad (referring to Fig. 2).

Above-mentioned handwriting is shaped as oblateness (referring to Fig. 2).

Above-mentioned place the useful artificial silk flosssilk wadding of handwriting in the body sleeve pipe to make and fullly soak the pen core overcoat of retouching the line ink, place the pen core that contains nib (referring to Fig. 1) of pen core overcoat, pen core can adopt plastics to make, disposable use.

An end that contains nib in the above-mentioned pen core stretches in the pen core overcoat and stretches out on the other end of pen core overcoat lever (referring to Fig. 1).

Scale (referring to Fig. 1) is arranged on the above-mentioned pen core, be convenient for measuring.

During work, can utilize this utility model to do disposable point, straight line setting-out, also rotatable handwriting is done the curved surface setting-out.

Compare with existing bow pen, the utlity model has following advantage:

1, use flexibly, drawing pen can be finished straight line at plane, curved surface, bent angle and the uneven place of skin, and describing of curve and point retouched more accurately and established wild border;

2, the line weight unanimity of retouching out, evenly attractive in appearance, and can go up firm, the persistent lines of formation at inhomogeneous skin (as oiliness, dry skin), line is accurately avoided improving the quality control of radiation because of retouching the coarse radiotherapy error that causes of the Line tool;

3, cost is low, and production technology is simple, can 1 of 1 people or many of people, fundamentally avoid the generation of cross infection, health;

4, good looking appearance, the Rad carries with easy to use.
