Technical Field

The utility model relates to the technical field of medical equipment, specifically a chain form skin mark structure for tumor radiotherapy.

Background

The medical apparatus refers to instruments, equipment, appliances, in-vitro diagnostic reagents and calibrators, materials and other similar or related articles directly or indirectly applied to the human body, and comprises required computer software, the medical apparatus comprises medical equipment and medical consumables, and the effect is mainly obtained through physical and other modes, not through pharmacological, immunological or metabolic modes, or only plays an auxiliary role though the modes participate. For the purpose of diagnosis, prevention, monitoring, treatment, or amelioration of a disease; diagnosis, monitoring, treatment, mitigation, or functional compensation of the injury; examination, replacement, regulation or support of a physiological structure or physiological process; support or maintenance of life; controlling pregnancy; by examining a sample from a human body, information is provided for medical or diagnostic purposes.

When a part of tumor patients are positioned by radiotherapy, the surface of the skin needs to be marked, and the mark can be developed on a CT image and used as a reference for delineating a target area. For example, Miles postoperative radiation therapy for rectal cancer requires marking of the surgical scar to facilitate identification of the surgical scar on the localized CT image, which is contained within the radiation therapy field. At present clinical lead that uses more, the lead can be imaged on CT scanning, important reference when delineating as the target area, and the lead is heavy metal material, and the metal artifact appears easily during CT formation of image, easily takes place unexpected damage risk when contacting with patient's skin to the lead need use repeatedly, and sanitary safety is difficult to the guarantee, needs to prepare in addition simultaneously and pastes the lead subsides on skin, and clinical use is inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides a chain form skin mark structure for tumour radiotherapy has solved present clinical use lead wire that uses more and has formed images on CT scanning, and the lead wire is heavy metal material, appears the metal artifact easily during CT formation of image, easily takes place the risk of accidental injury when with patient's skin contact to the lead wire needs to be used repeatedly, and sanitary safety is difficult to the problem of guarantee.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a tumour radiotherapy is with chain form skin mark structure, includes development pearl and connecting strip, a plurality of the development pearl is linear equidistance and distributes, and is connected through the connecting strip between two adjacent development pearls, every the bottom of development pearl is all fixed and is provided with the double faced adhesive tape subsides, the development pearl includes the plastic casing, the inside packing of plastic casing has the contrast-medium.

Furthermore, the connecting strip is made of the same material as the plastic shell and can be cut off by scissors.

Further, the contrast agent is an iodine contrast agent or a barium contrast agent or a diluent thereof.

Furthermore, the side face of the plastic shell is fan-shaped, the top of the plastic shell is oval, and the bottom of the plastic shell is a plane.

Furthermore, the double-sided adhesive tape is made of non-toxic and environment-friendly materials.

Advantageous effects

The utility model provides a chain-shaped skin marking structure for tumor radiotherapy. Compared with the prior art, the method has the following beneficial effects:

1. a chain-shaped skin marking structure for tumor radiotherapy is characterized in that a contrast agent for blood vessel development or digestive tract development is wrapped in a plastic shell and then attached to skin for marking corresponding areas of the skin. Compared with the prior clinical skin marking multipurpose lead wire, the lead wire has the following advantages: the developing bead has low manufacturing cost, is disposable and is more sanitary; the connecting bar has no metal component, and no metal artifact exists during CT imaging; the plastic shell is a plastic product, the risk of accidental skin injury of a patient is reduced, and the used material contrast agent and the plastic shell are both mature medical materials and are very safe.

2. A chain-shaped skin marking structure for tumor radiotherapy can enable a developing bead to be tightly attached to the skin of an examinee and is convenient to use clinically by adding a medical double-faced adhesive tape at the bottom of the developing bead.
