Description

Wall thickness thick radiation protection glove

Technical field

The utility model relates to the field of radiation protection, in particular to the field of radiation protection products, in particular to a variable wall thickness radiation protection glove. The utility model can be used for radiation protection, especially for X-ray protection, and has good protection effect and application prospect for the protection of the back of the doctor's hand when used for interventional surgery and orthopedic surgery.

Background technique

X-rays have the characteristics of short wavelength and strong penetrating power, and their characteristics such as fluorescence, photographic effect and biological utility are widely used in medicine. In most medical procedures (such as interventional surgery, orthopedic surgery), an X-ray machine is required. However, when the doctor performs X-ray diagnosis and surgery on the patient, the hand will be exposed to X-rays and scattering. The long-term effect will lead to hair follicle papules and hair loss reaction, erythema reaction, vesicular reaction and necrotic ulcer reaction in the doctor's hand skin. Different degrees of damage such as cancer. In order to reduce the damage of X-rays to the hands of doctors, lead rubber gloves are usually used for protection.

Lead rubber gloves have better protection effect against X-rays, but they have the following disadvantages: 1) The product is heavy and inconvenient to wear, and the fine operation affects the doctor's operation feeling; 2) Because lead is poisonous, long-term wear can lead to doctor lead poisoning; The post-treatment of lead rubber gloves is also a big problem. Based on the above shortcomings, most doctors are reluctant to wear during surgery or give up wearing lead rubber gloves.

The invention patent No. CN201010202804.1 discloses a radiation protection rubber protective glove and a preparation method thereof, which achieve about 50% attenuation of X-rays. Practice has shown that in order to achieve better protection, the protective gloves need to be made thicker. Therefore, the protective glove is only suitable for simple operation and cannot be used for fine operations such as interventional surgery or orthopedic surgery.

The invention patent No. CN201310399957.3 discloses a radiation protection protective glove and a preparation method thereof, which use polyacrylic acid ruthenium as a radiation protection material, wherein the mass fraction of the element lanthanum in the polyacrylic acid yttrium is about 42%, Mainly protective against radiation. In this application, a certain thickness of the glove should achieve a better protective effect, and the filling amount of the polyacrylic acid bismuth is inevitably higher, and in the case of a high filling amount, the mechanical properties such as the elasticity of the glove are greatly lowered. In the case of a certain amount of polyacrylic acid ruthenium filling, it is necessary to achieve better protection effect, and to maintain the mechanical properties such as the elasticity of the glove. The glove must be thick, and the thicker glove is only suitable for simple operation. For fine operations such as interventional surgery, orthopedic surgery.

Therefore, there is an urgent need for a new X-ray protective glove that can be used for flexible operation and non-toxic metal elements to effectively protect the health of medical personnel.
