Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a device for chest shielding and protection after tumor radiotherapy. Background Technology

[0002] Currently, breast cancer is the most common cancer among women worldwide. A survey showed approximately 357,200 new cases of breast cancer in Chinese women in 2022. Radiotherapy is one of the important treatment methods after breast cancer surgery, with about 50% to 70% of breast cancer patients requiring radiotherapy. Acute radiation dermatitis is the most common adverse reaction after breast cancer radiotherapy, with an incidence rate of 90% to 95%. Radiation damage is generally classified into grades 0-4 from mild to severe, mainly manifesting as skin pigmentation, erythema, itching, dry peeling, and wet peeling. Among these, 30% to 56% of patients will develop grade 2 or higher radiation dermatitis. Treatment involves applying topical preparations (such as medical moisturizing cream or silver sulfadiazine cream) followed by thorough drying and allowing the skin to absorb the product. When grade 3-4 radiation dermatitis occurs, if the patient wears clothing after applying topical medication, the ulcerated skin on the chest, the medication, and clothing can adhere, easily leading to secondary infection of the chest skin and hindering healing. This also increases the risk of cross-contamination within the ward, severely impacting the patient's subsequent treatment and quality of life. Post-radiotherapy patients are often required to expose their chest skin in the ward for better care, to reduce complications, and to accelerate the healing of radiation dermatitis. However, because the wards are open, family members can enter at any time, and exposing the chest skin does not consider the patient's privacy and psychological well-being, especially important for young female patients. Currently, there is no specific device for this purpose. The common approach is to use a screen or curtain to cover the patient's exposed chest skin around the bed. This significantly restricts the patient's movement and reduces space within the ward, negatively impacting subsequent treatment. Therefore, a technical solution is needed to address the above problems by allowing patients to wear clothes that allow them to move freely while covering their chest and protecting their skin after radiotherapy.

[0003] In summary, the present invention provides a device for chest shielding and protection after tumor radiotherapy. Summary of the Invention

[0004] The purpose of this invention is to provide a device for chest shielding and protection after radiotherapy for tumors. The technical problem this invention aims to solve is: by using a main frame combined with a snap-fit ​​chest protector and a rectangular frame, a 3-5 cm gap is created between the device and the skin, thus addressing the technical challenges of protecting the application of topical medications after breast cancer radiotherapy while preventing radiation dermatitis and protecting patient privacy.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A device for chest shielding and protection after tumor radiotherapy includes: a main frame, a back strap, a left chest shield seat, a connecting rod, a top support, hooks, a connecting strap, a neck fixation strap, side panels, elastic bands, frame slots, Velcro, a side support, a right chest shield seat, shield slots, a bottom support, a central connecting rod, a chest shield, hooks, padding, arc-shaped blocks, shielding fabric, a steel wire frame, an inner lining, bosses, a shield base, and a rectangular frame. The main frame of the device is U-shaped, with frame slots on both sides. Side panels are fixed around the main frame, with padding adhered to the inner side of the side panels. A top support and a bottom support are fixed at the top and bottom of the main frame, respectively. Side supports are fixed on both sides. The left and right chest shield seats are fixed to the top support, bottom support, and side support respectively via connecting rods. The left and right chest shield seats are connected by a central connecting rod. The two chest shields are snapped into the left and right chest shield seats respectively. The rectangular frame is snapped into the main frame. A shoulder strap is fixed to one side plate of the main frame, and an elastic band is fixed to the shoulder strap. Velcro is fixed to the other side plate. A connecting strap is fixed to the neck fixation strap. A hook is fixed to the end of the connecting strap. Velcro is fixed to the ends of the shoulder strap and the neck fixation strap. A hanging ear is fixed to the top of the main frame and connected to the neck fixation strap via a hook and connecting strap.

[0007] The device has corresponding shield slots on the left and right breast shield seats. The bottom of the breast shield has an arc-shaped locking block corresponding to the shield slot. The end of the arc-shaped locking block has a boss. The shield base is engaged with the shield slot through the boss.

[0008] The device has a steel wire frame on the base of the chest shield at the bottom. A shielding cloth is fixed to the outside of the steel wire frame, and an inner lining cloth is fixed to the inside of the steel wire frame.

[0009] The device has a shielding cloth fixed to the top of the rectangular frame, and protrusions are provided at the bottom of the two side frames of the rectangular frame. The rectangular frame is engaged with the frame slots on both sides of the main frame through the protrusions.

[0010] The main frame, left chest shield seat, side plate, right chest shield seat, shield base, and rectangular frame of the device are made of medical-grade rigid elastic PVC material. The shoulder straps, connecting straps, and neck fixing straps are made of sturdy and durable cotton material. The cover cloth and inner lining cloth are made of soft and breathable cotton material.

[0011] The chest bras involved in the device can be made in small, medium, large, and extra-large sizes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The main frame of the device has a U-shaped structure, combined with a snap-fit ​​chest protector and a rectangular frame, which creates a 3-5 cm gap between the device and the skin. This protects the topical preparations applied to the skin, prevents radiation dermatitis infection, and protects the patient's privacy.

[0014] 2. This device uses a chest shield or a covering cloth on a rectangular frame to cover the chest of the patient (female or male) through the main frame, while allowing the patient to wear clothes and move freely after radiotherapy and treatment.

[0015] 3. The device has hooks on the main frame that are connected to the neck straps via connecting straps to position and fix the main frame vertically. The back straps and Velcro on the back panel are used to position and fix the main frame horizontally.

[0016] 4. The device has corresponding bra slots on the bra holder to facilitate the bra's snap-fit, and frame slots on both sides of the main frame to facilitate the snap-fit ​​of the rectangular frame.

[0017] 5. This device creates a certain space inside the bra by setting a steel wire frame, a covering cloth, and a soft inner lining on the bra. At the same time, the covering cloth and the soft inner lining can provide good skin protection and chest coverage.

[0018] 6. The device has a reasonable structural design, is simple, convenient and practical to operate, and has low economic cost, which greatly reduces medical expenses. It can be widely used in clinical treatment and is suitable for most hospitals and medical research institutions. Attached Figure Description
