Marker acting on human epidermis and used for carrying out marking before radiotherapy

Abstract

The invention discloses a marker acting on a human epidermis and used for carrying out marking before radiotherapy. The marker comprises a shell and a pen point. The marker comprises the handheld shell and the pen point, wherein a solution box is mounted in the shell, a gentian violet solution is contained in the solution box, a valve plate is slidably connected in the solution box, the valve plate is fixedly mounted at the axis of the shell through a vertical rod, and a pressing plate slides downwards to drive the solution box to slide downwards. According to the marker acting on the human epidermis and used for carrying out marking before the radiotherapy, a supply structure of a dyeing solution is redesigned, the pen point in the marker can stably discharge liquid to achieve a marking purpose in a one-time-pressing continuous liquid-supply mode, and the purpose of direct marking without contacting the skin of a patient can be achieved by taking the same pressing acting force as a driving force, so that suffering increase caused by direct contact between the skin and a marking structure after the skin is damaged by the radiotherapy is avoided, and the marking effect is clearer and more complete.

Description

technical field [0001] The invention relates to the technical field of radiotherapy equipment, in particular to a marker for marking before radiotherapy that acts on human epidermis. Background technique [0002] In the process of radiotherapy, radiation can not only destroy the lesion cells, but also cause different degrees of damage to the epidermis, skin and visceral trachea due to contact with the epidermis, skin and internal organs. , the medical staff will use the corresponding markers to mark the radiotherapy area to facilitate the precise operation of the radiotherapy staff, but the existing markers still have the following problems in actual use: [0003] Most of the existing markers are simple marking pen structures. In actual use, when the internal gentian violet solution pigment is exhausted, different inner cores need to be replaced. The staff cannot add and replace the solution independently, and frequent The use cost caused by the replacement will also increa...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a marker for marking before radiotherapy that acts on the human epidermis, to solve the problem that the existing markers proposed in the above-mentioned background technology are mostly simple marker pen structures. After the bilirubin solution pigment is exhausted, different inner cores need to be replaced. The staff cannot add and replace the solution independently, and the use cost caused by frequent replacement for a long time will also increase accordingly. The existing syringe-like marker structure cannot be used On the premise of not using driving equipment such as motors, a relatively long-term continuous supply of the solution is achieved, which leads to a further increase in the cost of other types of markers
