Description

TECHNICAL FIELD

[0001] The utility model relates to medical auxiliary instrument technical field especially, a device that can avoid breast tissue compensation cross infection. BACKGROUND

[0002] Breast cancer is one of the common female tumors, the latest cancer data report released by the World Health Organization (WHO) International Cancer Research Agency on April 4, 2024 in Clinical Oncologist Cancer Journal shows that in 2022, the global new cancer cases are 19.96 million, and the incidence rate of breast cancer ranks second. More than half of the patients received modified radical mastectomy, for the patients with postoperative radiotherapy indication, radiation therapy plays a key role in reducing the recurrence rate and improving the local control rate.

[0003] Because of the dose building effect of high-energy rays, the maximum dose of rays entering the human body tissue appears in the tissue at a certain depth from the body surface, not on the surface of the human body tissue, so the treatment of superficial tumors such as breast cancer needs to cover the tissue compensation on the surface of the patient's body to improve the radiation dose absorption of the tumor area. The commonly used tissue compensation in clinical practice includes membrane tissue compensation and non-membrane tissue compensation. The membrane tissue compensation is made of silicone or polystyrene material into a sheet-shaped tissue compensation, and then packaged into a product with a film. The non-membrane tissue compensation is not packaged with a film.

[0004] To ensure that the tissue compensation can effectively improve the radiation dose of the superficial tumor, so that the actual absorbed dose of the patient is consistent with the radiotherapy plan, the tissue compensation should be used as much as possible to reduce the fitting gap between the tissue compensation and the body surface in clinical practice. The membrane tissue compensation can isolate dust and patient body fluid pollution, and can be reused between different patients, but the fitting of the membrane tissue compensation with the patient's body surface is not ideal. The non-membrane tissue compensation has adhesion due to the material, so the fit of the compensation with the patient's skin is good, and the placement state of the tissue compensation during simulation positioning can be better restored in each treatment, reducing the dose error in the process of radiotherapy irradiation execution, but the non-membrane compensation will stick to the patient's body fluid and dust, and cannot be used between different patients, for example, a general radiotherapy room usually has only one or two public breast tissue compensations. In the later stage of treatment, some patients may have different degrees of radiotherapy reaction, and in severe cases, may have ulceration and exudation, which may contaminate the tissue compensation, causing cross infection when other patients use the breast tissue compensation. At the same time, even if a person is dedicated, it will also cause infection when the tissue compensation is repeatedly used due to the ulceration of the patient's skin.

[0005] In addition, when the treatment is carried out in cold weather, directly attaching the tissue compensation to the patient's body surface will cause discomfort to the patient.

[0006] Therefore, it is necessary to design a device capable of avoiding cross infection of breast tissue compensators to solve the above problems. Utility model content

[0034] In addition, it also needs to be explained that the term "comprises", "includes" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0035] Please refer to Figs. 1-2 The utility model provides a device for avoiding cross infection of breast tissue compensation objects, which comprises:

[0036] A support 10;

[0037] A conveying mechanism is arranged on the support 10 and comprises a conveying belt 20 and a driving structure for driving the conveying belt 20 to rotate circularly.

[0038] A roll-shaped protective film is arranged on one side of the conveying belt 20 and comprises a film 32 with adhesive on both sides and a release paper 33 adhered to the film 32.

[0039] A winding roller 40 is arranged on the side of the conveying belt 20 away from the roll-shaped protective film, the winding roller 40 is connected to the output end of the roll-shaped protective film, so that the side of the film 32 with the release paper 33 is covered on the conveying belt 20, forming an adhering area 34 on the conveying belt 20, which is convenient for the film 32 to adhere to the surface of the tissue compensation object.

[0040] A first driving member is used to drive the roll-shaped protective film and the winding roller 40 to rotate synchronously.

[0041] A heating structure is arranged below the conveying belt 20 and is used to heat the film 32 on the conveying belt 20.

[0042] For example, the roll-shaped protective film comprises a reel 31 fixed on the support 10 through a first connecting rod 311 and a protective film body formed by the film 32 and the release paper 33, the protective film body is wound on the reel 31; the first driving member is connected to the reel 31, so that under the action of the first driving member, the reel 31 and the winding roller 40 rotate synchronously, and the protective film body moves towards the winding roller 40.

[0043] The winding roller 40 is fixed on the support 10 through the second connecting rod 41.

[0044] The film 32 is a silicon film with adhesive on both sides, and the thickness of the silicon film is 0.2-0.5cm. The release paper 33 has smooth surfaces on both sides.

[0045] Specifically, the protective film body is provided with a point-breaking tear line 35 for facilitating the removal of the film 32 and the release paper 33 of the adhesive area 34.

[0046] Since the conventional radiotherapy room generally has two common film-free breast tissue compensators, for example, two adhesive areas 34 are arranged on the conveying belt 20 along the moving direction of the conveying belt 20.

[0047] Specifically, the conveying belt 20 is provided with a brake sensor 50 at the end away from the winding protective film, so as to control the start and stop of the driving structure and the first driving member through the brake sensor 50, and further control the movement of the conveying belt 20 and the protective film body. For example, the brake sensor 50 is an optical sensor; the two adhesive areas 34 on the conveying belt 20 are connected to the side close to each other, so that when the protective film body on the adhesive area 34 close to the brake sensor 50 is removed, a through hole 70 is formed at the position (as shown in FIG. 6), Fig. 2 the optical sensor emits a signal to the conveying belt 20 to control the driving structure and the first driving member to run, at this time, the conveying belt 20 and the protective film body move synchronously to the direction close to the brake sensor 50, and when the protective film body moves to the preset position, the brake sensor 50 emits a signal to the protective film body to control the driving structure and the first driving member to stop driving.

[0048] For example, the length of the conveying belt 20 is 70cm, and the width is 50cm; the size of the tissue compensator commonly used in the room is 30×30×0.5cm (or 30×30×1cm), that is, two adhesive areas 34 are formed on the conveying belt 20, and two tissue compensators can be placed side by side according to the needs.

[0049] Specifically, the size of the protective film body can be designed according to the actual use needs. For example, the width of the film 32 is equal to the width of the tissue compensator, which is 30cm, and the width of the release paper 33 is 40cm; the adhesive area 34 is equal in size to the tissue compensator, and the length and width are both 30cm; the point-breaking tear line 35 is arranged around the adhesive area 34, so that when the film 32 and the release paper 33 of the adhesive area 34 are torn along the point-breaking tear line 35, the remaining release paper 33 is wound on the winding roller 40 for collection, and the winding roller 40 is used for rotating with the winding shaft 31 to facilitate the output of the protective film body, and the winding roller 40 is also used as a waste release paper 33 collection member.

[0050] Specifically, the heating device comprises a base 61 located below the conveying belt 20 and a heating resistance wire 62 connected to the base 61, and the base 61 is further provided with a switch 63 for controlling the working state of the heating resistance wire 62, a temperature control key 64 for controlling the heating temperature, and a temperature display window 65 for displaying the heating temperature, so as to adjust the heating temperature of the heating resistance wire 62 according to the indoor environmental temperature and the patient's body feeling. Specifically, the heating temperature of the heating device ranges from 25 to 40℃.

[0051] Specifically, the driving structure is capable of driving the conveying belt 20 to rotate circularly, so that the conveying belt 20 and the protective film body located thereon move synchronously, and then the protective film body is supported by the conveying belt 20. The specific structure of the driving structure can refer to the existing structure in which two driving rollers rotate synchronously to control the circular rotation of the conveying belt 20, which will not be described herein.

[0052] Specifically, the first driving member is a driving motor.

[0053] In use, the conveying belt 20 and the protective film body are controlled to move synchronously by the driving structure and the first driving member, so that two adhesive areas 34 are formed on the conveying belt 20, and the heating device is controlled to heat according to the needs, so that the temperature of the adhesive area 34 is increased; the tissue compensation object is placed on the adhesive area 34 close to the braking sensor 50, and when the temperature of the tissue compensation object is increased to a temperature that is comfortable for the patient's body feeling, the protective film body, i.e. the film 32 and the release paper 33, of the adhesive area 34 is torn along the point-and-break tear line 35, so that the film 32 forms a protective layer on the surface of the tissue compensation object; then the release paper 33 is torn, and the film 32 is adhered to the patient's skin, i.e. the tissue compensation object is better attached to the surface of the patient's skin. When the current patient uses up the tissue compensation object, the film 32 is torn, and the tissue compensation object is placed on the adhesive area 34 using a new film 32 as a protective layer, so that the tissue compensation object can be used on the skin of the next patient, and the film 32 is used as a protective layer to avoid cross-infection between different patients.

[0054] When the protection film body close to the adhesive area 34 of the brake sensor 50 is removed, the brake sensor 50 detects the signal to control the driving structure and the first driving member to operate, so that the conveying belt 20 and the protection film body are synchronously moved to the direction close to the winding roller 40 to form two adhesive areas 34 on the conveying belt 20, and then the brake sensor 50 sends the signal to stop the driving of the driving structure and the first driving member. By arranging the brake sensor 50, the automatic control of the conveying belt 20 and the protection film body can be realized, so that two adhesive areas 34 are always formed on the conveying belt 20, which facilitates the medical staff to place the tissue compensation material on the adhesive area 34, forms the protection layer on the surface of the tissue compensation material by using the film 32, and also prevents the heated tissue compensation material from moving with the conveying belt 20 and sliding from the side of the conveying belt 20, and the arrangement of the two adhesive areas 34 on the conveying belt 20 can ensure that one tissue compensation material is always in the heating standby state, greatly improves the treatment efficiency, and can obviously improve the ice-cold uncomfortable feeling of the patient during use.

[0055] The above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
