Technical Field

The invention relates to the field of medical instruments, in particular to a scalp dose compensator for scalp tumor radiotherapy.

Background

Electronic radiation is most commonly used for the radiotherapy of scalp tumors, and dose compensators are required to be placed on the surface of the scalp during the radiotherapy process to increase the scalp dose, otherwise, insufficient scalp dose can be caused.

The dose compensator sold in the market at present is mainly flat and square, and due to the particularity of the scalp outline, on one hand, the dose compensator and the scalp cannot be completely attached, and an air gap is generated between the dose compensator and the scalp to influence the dose distribution of radiotherapy; in addition, the square agent compensator is difficult to fix on the scalp and often slides off in the treatment process, thereby reducing the dose of the electronic ray received by the scalp in the radiotherapy process. The traditional dose compensators generally affect the curative effect of scalp tumor radiotherapy due to the problems.

Disclosure of Invention

The present invention is directed to the above-mentioned problems and provides a cap-shaped scalp dose compensator, which is intended to closely attach a scalp to a dose compensator, reduce a gap between the scalp and the dose compensator, and prevent the dose compensator from falling off.

In order to solve the technical problem, the scalp dosage compensator is in a hat shape and is made of paraffin or polystyrene material, the thickness of the compensator is equal everywhere, the front side of the compensator covers the eyebrow arch, the rear side of the compensator covers the upper neck, and the two sides of the compensator cover the upper edge of the auricle. The cap-shaped structure can be manufactured into corresponding thickness and diameter according to requirements, and different scalp dosage compensators can be selected according to dosage compensation requirements and the head circumference of a patient in clinical use.

Advantageous effects

1. The compensator adopted by the invention is in a cap shape, can be tightly applied to the surface of the scalp, avoids or reduces the air gap between the dose compensator and the scalp, and obtains better radiation treatment dose distribution; the scalp-fixing agent is easier to fix with the scalp in the using process, and the risk of slipping of the dosage compensators in the treatment process is reduced.

2. The scalp dose compensator comprises scalp dose compensators with different thicknesses and diameters, can be selected according to clinical dose compensation requirements and head circumference, and has the advantages of simple structure and convenient use.

Detailed Description

A scalp dose compensator 1 for radiotherapy is a cap-shaped structure made of paraffin or polystyrene material, the thickness of the cap-shaped structure is equal everywhere, the front part of the cap-shaped structure covers the eyebrow arch, the back part covers the upper neck, and the two sides cover the upper edge of the auricle. The cap-shaped structure can be manufactured with corresponding thickness and diameter according to requirements. The scalp dose compensator with the proper thickness is selected according to the clinical needs of the patient, and the scalp dose compensator with the proper diameter is selected according to the head circumference of the patient. The patient is placed in the accelerator treatment position, and treatment is performed using the selected scalp dose compensator. The scalp dose compensator is removed after the radiotherapy is finished.

In order to ensure that the scalp dose compensator is tightly attached to the scalp, so that no gap exists between the dose compensator and the scalp, and the scalp dose compensator is prevented from falling off, the scalp dose compensator adopts a cap-shaped form, and scalp dose compensators with different diameters are selected according to the head circumference of a patient. To meet the different dosage compensation requirements of the clinic, scalp dosage compensators of different thicknesses can be selected.

The above description is for the purpose of describing the present invention in detail, and is not intended to limit the present invention, and variations, modifications, additions and substitutions which may be made by those skilled in the art within the technical scope of the present invention are included in the present invention.
