Embodiment 1

[0015] Embodiment 1, decontamination effect experiment

[0016] 1. Selection and acquisition of radionuclides

[0017] Buy CoCl 2 , by low dose rate fission neutrons ( 252 Cf, absorbed dose rate 0.35mGy / h) irradiated for 2 months to produce activated products 60 Co, 131 I was provided by Huangpu District Central Hospital.

[0018] 2. Establishment of wound and abrasion models

[0019] Small fragrant pigs, 40mg / kg, intraperitoneal injection of pentobarbital sodium, skin preparation, skin well-shaped incision.

[0020] 3. Screening of physical materials

[0021] Select microporous sponges, non-woven fabrics, and medical gauze (materials with high adsorption capacity and gentle contact surface), respectively take materials of the same area and weight, and add physiological saline dropwise until it oozes out to compare water absorption; , skin preparation, cutting 3cm × 3cm, divided into 4 groups (blank group, sponge wiping group, non-woven cloth wiping group, medical gauze...

Embodiment 2

[0049] Embodiment 2, stimulating experiment

[0050] 1. Wound irritation test:

[0051] New Zealand rabbits, 8 rabbits, half male and half male, the hair on both sides of the back was cut short and then depilated. The depilated area was 3cm×3cm each. Group (intact skin group I, damaged skin group II), experimental group (intact skin group III, damaged skin group IV), artificial wounds, 0.5ml (g) of the mixed group decontamination solution was directly coated on the wounds, and used Cover and fix with two layers of gauze (2.5cm×2.5cm) and a layer of cellophane. The skin on the other side is used as a control. Apply the negative control and apply for 4 hours. After the test, remove the remaining test samples with warm water. Observe the skin reaction at the site where the test sample was administered 1, 24, 48, and 72 hours after the test sample was removed, and determine the wound irritation intensity. According to the standard score of skin erythema, edema formation and woun...

Abstract

The invention relates to the technical field of medical instruments and in particular relates to a decontamination bag for radionuclide contamination of skin and wounds. The invention discloses a decontamination bag for skin radioactive contamination, which comprises a water absorbent pad and a decontamination liquid. The invention is characterized in that the decontamination liquid is an aqueous solution containing 0.5% to 10% of EDTA, 0.5% to 10% of citric acid, 0.5% to 20% of bleaching powder and 0.5% to 10% of fatty alcohol polyoxyethylene ether sodium sulfate. The decontamination bag is available in disposable package and has the characteristics of having a small size and being convenient to carry and store and convenient to use. The decontamination bag can eliminate radionuclide contamination of skin and wounds without needing water washing, reduces secondary contamination, has good decontamination effects, and is applied to workers of nuclear power, nuclear reactors and radiation devices in both army and local areas for radiation decontamination in case of nuclear emergency.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a decontamination bag used for skin and wound contamination with radionuclides. Background technique [0002] At present, there are relatively mature military and commercial technologies for the decontamination of the normal body surface of personnel and large-area decontamination, while the decontamination technology for small sensitive devices and personnel radioactively contaminated wounds is still in the stage of development, exploration and experimentation. For this reason, domestic and international efforts are being made to find effective and applicable technologies and equipment for decontaminating sensitive equipment and personnel wounds. The skin decontaminants commonly used in foreign countries include porous strips, bar soap, anhydrous hand sanitizer, soft brush or LAVA soap. Russia has been equipped with IPP-3 disinfection boxes for decontamination of individ...
