Abstract

The invention provides a special ink pen for radiation treatment, which consists of a large pen cap, a small pen cap, a large pen tip, a small pen tip, a circular pen point, an ink cavity, a large pen cap, a left triangular sheet, a right triangular sheet, a long pen pointer and a pen holder. The ink cavity is hollow, water absorption stuffing is installed inside the ink cavity, the circular pen pointer is fixedly connected with the small pen tip, the long pen pointer is fixedly connected with the large pen tip, the two pen pointers are connected with the ink cavity, the small pen tip and the large pen tip are respectively and movably connected with the pen holder, the ink cavity is arranged inside the pen holder, the two triangular sheets are symmetrically fixed at two sides of the large pen tip, and a triangular bottom edge of each two triangular sheet is vertical to the long pen pointer to form a cross shape. By the special ink pen for the radiation treatment, the difficulty that the line drawn on a radiation-treatment body is uneven is overcome, convenient and accurate positioning of drawn lines before the radiation treatment can be realized, the healing effect can be improved, and a practical tool is provided for the clinical radiation treatment. The special ink pen for the radiation treatment is simple and convenient to produce, not only can functions of an original ink pen be maintained, but also the special pen tip for drawing lines during the radiation treatment can be provided, the lines on the body surface can be maintained clear when the special ink pen is in use, the ink pen can be used for multiple times, and the application cost can be saved.

Description

The special-purpose water-color paintbrush of a kind of radiotherapy

Technical field

The invention belongs to field of medical devices, relate to the special-purpose water-color paintbrush of a kind of radiotherapy, be applied to the radiotherapy doctor and in tumour radiotherapy, make witness marker line etc.

Background technology

At present; In tumour radiotherapy; The radiotherapy doctor must to patient fixed model or body surface carry out setting-out; Especially more with cross shape, the method that adopts is common water-color paintbrush and dyeing small wood at present, the water-color paintbrush nib is less; 2.5 centimetres the lines of length of painting tend to the not straight of picture; When the dyeing small wood is taken out line at every turn in the dyestuff bottle, tend to allow the dyestuff globule drop to the ground of machine room, that draws on patient's body surface and the body film is also inhomogeneous.

Summary of the invention

The objective of the invention is in order to overcome the deficiency that prior art exists, provide a kind of radiotherapy special-purpose water-color paintbrush, by the little cap for brush, circular nib, inking chamber, the big cap for brush, left triangle matrix, right triangle matrix, the elongated nib, penholder, little nib, big nib is formed.Inking chamber is a hollow, in the suction filler is arranged, circular nib and little nib are affixed; The tail end of circular nib directly inserts in the inking chamber; Fix with inking chamber on the one hand, suck ink simultaneously, offer circular nib; Equally; The elongated nib is affixed with big nib, and the tail end of elongated nib directly inserts in the inking chamber, fixes with inking chamber on the one hand; Suck ink simultaneously; Offer the elongated nib, rectangular nib is long to be 2.3cm-2.8cm, little nib and big nib and penholder flexible connection; Can shirk; Inking chamber places in the penholder, when ink uses up, can unload little nib or big nib; In inking chamber, pour into ink; Left side triangle matrix and right triangle matrix symmetry are installed in the both sides of big nib, and the triangular form base is vertical with the elongated nib, form cross; the little cap for brush is placed in outside the circular nib, and a large sum of cap sleeve is outside the elongated nib.

Left side triangle matrix and right triangle matrix can be plastics one-shot forming preparation with big nib.

Marking pen provided by the invention has overcome the uneven difficult problem of setting-out in the past, has realized the preceding setting-out of promptly convenient radiotherapy accurately again location, for clinical radiotherapy provides instrument.Marking pen provided by the invention, simple for production, promptly keep the function of original water-color paintbrush, provide the radiotherapy line special-purpose nib again, and can repeatedly use through irritating ink, making, practice thrift use cost.Can keep the body surface svelteness in the use, it is radium-shine accurate to guarantee, improves curative effect.

The specific embodiment

The present invention combines accompanying drawing and embodiment to be further described.

Embodiment 1

Referring to Fig. 1,2, the present invention is by the little cap for brush 1, circular nib 2, and inking chamber 3, the big cap for brush 4, left triangle matrix 5, right triangle matrix 6, elongated nib 7, penholder 8, little written 9, big nib 10 is formed.Inking chamber 3 is a hollow; In the suction filler is arranged; Circular nib 2 is affixed with little written 9; The tail end of circular nib 2 directly inserts in the inking chamber 3; Fixing with inking chamber 3 on the one hand, suck ink simultaneously, offer circular nib 2; Equally; Elongated nib 7 is affixed with big written 10, and the tail end of elongated nib 7 directly inserts in the inking chamber 3, and is fixing with inking chamber 3 on the one hand; Suck ink simultaneously; Offer elongated nib 7, rectangular nib 7 length are 2.3cm-2.8cm, and little written 9 with nib 10 and penholder 8 flexibly connect greatly; Can shirk; Inking chamber 3 places in the penholder 8, when ink uses up, can unload little written 9 or big by written 10; In inking chamber 3, pour into ink; Left side triangle matrix 5 is installed in big written 10 both sides with right triangle matrix 6 symmetries, and the triangular form base is vertical with elongated nib 7, forms cross; the little cap for brush 1 is placed in outside the circular nib 2, and the big cap for brush 4 is placed in outside the elongated nib 7.

Embodiment 2

Use when of the present invention; At indoor machine room; Open radiotherapy simulative generator earlier; Then open laser lamp; According to doctor's advice patient is put the position; After accomplishing the pendulum position; Make the cross laser line be radiated at patient's body surface or body film; Again big written 10 ends of marking pen of the present invention are placed patient's body surface or body film; Make to overlap with the laser rays cross with the elongated nib 7 vertical cross that form, utilize elongated nib 7 to delineate straight line, rotate 90 degree again by the triangular form base; In like manner delineate an other straight line, accomplish delineate (referring to Fig. 3) of a cross hairs perpendicular to article one.Cross of so delineating and laser rays cross fit like a glove, and have overcome the uneven difficult problem of setting-out in the past, have realized the preceding setting-out of promptly convenient radiotherapy accurately again location, for clinical radiotherapy provides instrument.

Circular nib 2 of the present invention can be used for conventional mark to be write, also can delineating at patient's body surface point.
