Definitions

  • the present invention relates to X-ray protective clothing, in particular for protecting a user from X-rays emitted by an X-ray source.
  • X-ray protective clothing is used in medical X-ray applications, e.g. by staff (examiners, surgeons, assistants) to keep the body dose low.
  • the conventional concept is essentially based on a more or less uniform coverage of the entire body from the neck to the knees.
  • the protection levels usually correspond to 0.25/0.35/0.50 mm lead or lead equivalent.
  • the lead equivalent is determined according to the “International Electrotechnical Commission IEC. Protective devices against diagnostic medical X-radiation. IEC 6133 IPart 1 : Determination of attenuation properties of materials (2014)”.
  • aprons with 0.35 and 0.50 mm Pb are used most frequently. Depending on body size and the materials used, these aprons have weights of around 5 to 9 kg, particularly in the version that covers the front and back of the body. Due to the relatively high weight of the aprons, the wearing comfort is low.
  • protective clothing due to the high static load in connection with the vapor impermeability of the protective clothing, protective clothing represents a high physical strain on the user, which can also be reflected in the quality of work and/or lead to diseases of the musculoskeletal system.
  • US 3,310,053 relates to X-ray protective undergarments and more particularly to undergarments having support properties and other undergarments providing gamma ray protection in certain selected areas.
  • US 10,276,273 B2 relates to protection against ionizing radiation and in particular to a radiation protection device and a radiation protection method for use in space.
  • a device for protecting a body from radiation comprising at least one flexible garment. Each section of the flexible garment is configured to shield an area of a body surface.
  • US 2019/0027262 A1 relates to radiation protection clothing for limiting the radiation exposure of radiographers and assistants at the time of radiography Use of a lightweight lead-free shielding sheet for X-ray shielding, the radiation protective clothing comprising: an upper main body having a torso portion; and a shielding sheet at least a part of which can be attached to or detached from the upper main body using attachment and detachment means.
  • US 2019/0043628 A1 relates to a lightweight radiation protection plate that consists of a radiation protection layer and a flexible material.
  • the radiation shielding layer consists of a multitude of shielding material distributed in repeating and adjacent units of geometric shapes, the lightweight radiation shielding wall can be embedded in a wearable garment that offers flexibility.
  • EP 1 052 652 B1 relates to radiation protection consisting of a lower apron and an upper apron, with the lower and upper apron overlapping in the front area and the lead equivalent value in the front area is doubled compared to the back area.
  • the object of the present invention is to provide X-ray protective clothing which is improved over the prior art.
  • X-ray protective clothing for protecting a user from X-rays emitted by an X-ray source.
  • the X-ray protective clothing has a first X-ray protective clothing with a first X-ray protective material with a first lead equivalent and a second X-ray protective clothing with a second X-ray protective material with a second lead equivalent.
  • the second X-ray protective clothing overlaps the first X-ray protective clothing in a predetermined area.
  • the first and second lead equivalents combine to provide a predetermined protection against x-rays in the predetermined overlapping area.
  • the first X-ray protective clothing can be referred to as an underapron (apron close to the body) and the second X-ray protective clothing as an upper apron (apron away from the body). At least part of the second X-ray protective clothing thus lies over the first X-ray protective clothing and thus forms the above-mentioned overlapping area.
  • the first and/or second X-ray protective clothing can each be made up of one or more layers.
  • the first lead equivalent may be less than, preferably greater than or equal to the second lead equivalent, the first lead equivalent preferably being Pb 0.10 mm to Pb 1.00 mm and the second lead equivalent preferably being Pb 0.10 to 0.50 mm, where the first lead equivalent is particularly preferably Pb 0.175 mm or Pb 0.25 mm and the second lead equivalent is particularly preferably Pb 0.25 mm.
  • the first and/or second X-ray protective clothing preferably covers the following areas or organs of the user: the intestines and/or the stomach and/or the urinary bladder and/or the gonads and/or the bone marrow and/or the liver and/or the Mammary glands and/or the sternum and/or the thyroid of the user and/or the lungs and/or the esophagus and/or the shoulder joints and/or the humerus bases, preferably at least on the front of the user.
  • the first and second X-ray protective clothing covers at least the aforementioned areas or organs of the user. Increased protection against X-ray radiation can thus be achieved for the aforementioned organs/body regions of the user, which are particularly sensitive to radiation, and at the same time less protection against X-ray radiation can be provided for the less radiation-sensitive parts of the user's body. As a result, the weight of the radiation protection clothing can be reduced.
  • the first X-ray protective clothing may cover at least an area from the gonads to the lower breast base or across the chest of a user, wherein the first X-ray protective clothing preferably also covers the thyroid area and/or the shoulder joint and upper arm area of the user.
  • the areas or organs of the user covered by the first and second X-ray protective clothing preferably correspond to the predetermined overlapping area.
  • the area covered by the first X-ray protective clothing preferably corresponds to the predetermined overlapping area.
  • the second X-ray protective clothing may have at least an area from the sternum to the knees, or an area from the sternum to the gonads, or an area from the sternum to an area between the gonads and the knees, or an area from the upper abdomen to the gonads, or a Area from the chest to the gonads of the user, the second X-ray protective clothing preferably additionally covering an area from the thyroid to the sternum of the user.
  • the gonads lie below the pubic bone in male users and above it in female users.
  • the pubic bone may or may not be included.
  • the corresponding X-ray protective clothing covers at least the pubic bone or at least the gonads (in the case of a male user).
  • the appropriate X-ray protective clothing can reach at least 10 cm below the pubic bone.
  • the first and/or second X-ray protective clothing can have uniform or different zones with uniform or different lead equivalent values.
  • the second X-ray protective clothing can have a uniform lead equivalent value, with at least one of the zones preferably corresponding to the predetermined overlapping area.
  • the predetermined overlapping area is preferably arranged on the front of the user, with the second X-ray protective clothing and/or the first X-ray protective clothing preferably covering at least 50%, particularly preferably at least 60%, of the body circumference of the front of the user.
  • the second X-ray protective clothing can only partially overlap the first X-ray protective clothing or essentially completely overlap.
  • the predetermined area of overlap may correspond to at least an area from the user's pubic bone or gonads to the sternum.
  • the first X-ray protective apparel may include one or more first support devices configured to support the weight of the first X-ray protective apparel on the user's body, preferably on the user's shoulder and/or waist or hip.
  • the second X-ray protective apparel may include one or more second support devices configured to support the weight of the second X-ray protective apparel on the user's body, preferably on the user's shoulder and/or waist or hip.
  • the first and/or second carrying device can be, for example, a stretch belt that supports the weight on the user's waist or hips.
  • the first and/or second carrying device can also be a shoulder strap, for example, which supports the weight on the user's shoulder.

  • the second X-ray protective clothing and/or the first X-ray protective clothing can be completely or partially free of X-ray protective material on the back of the user.
  • the X-ray protective clothing thus preferably has protection from the combination of the protective effects of the first and second X-ray protective clothing in the overlapping area and a simple protective effect in accordance with the protective effect of the first or second X-ray protective clothing in the non-overlapping area.
  • the X-ray protective clothing in the overlapping area has increased protection compared to the non-overlapping area.
  • the patient lies on the X-ray table during the X-ray application. This applies to almost all interventions and angiographies. A standing application only occurs, for example, in bronchoscopy.
  • Table 1 Shares of the organ doses in the total dose of the examiner with the patient lying down
  • the present invention is based on a two-part apron, consisting of an under apron and an over apron. Because of the additional protection of the lower body provided by the under apron, the over apron may have a lower lead equivalent value, e.g. B. 0.25 mm instead of the usual 0.35 or 0.50 mm and thus be much lighter.
  • the partial apron on the lower body which preferably extends from the gonads to the sternum, protects the main organs that are sensitive to radiation.

  • the apron is preferably constructed in two parts (under apron + over apron).
  • the apron can also be constructed in one piece, in that the apron material is reinforced in the area of the lower body and/or other areas or body regions.
  • the apron can z. B. by Velcro strips in the apron as an additional part.

  • the present invention is based in particular on the combination of two aprons, the under-apron not being confused with a lower-body apron.
  • the high protective effect or total protective effect is only achieved through the combination of both items of clothing, i.e. through the addition of the lead equivalent values in the overlapping area.
  • the present invention relates in particular to a protective material distribution on the body in such a way that the effective dose (sum of the weighted organ doses) is minimized.
  • the protective clothing can be made lighter than protective clothing with homogeneous lead equivalent values.
