Description
Technical field
The utility model category field of medical devices is related to a kind of radiation protection device for medical purpose more particularly to medical radioactive
Brachytherapy radioprotector.It is anti-when transport process and ward are hospitalized after performing the operation applied to radioactive prospecting instrument patient
Harm of the ray that only medical radioactive particle generates to medical staff and surrounding population.
Background technology
Currently, in the treatment of tumour patient, radioactive prospecting instrument is gradually applied to controlling for multinomial malignant tumour
It treats, because its dosage is reliable, local controlled makes, and appeases or redemption effect is apparent, improve life quality, more and more by numerous doctors
It is raw to approve and receive with patient.But patient's radioactive prospecting instrument operation after be transported to ward during and be hospitalized during it is right
There are larger radiation hazradial bundles for medical staff and surrounding population.
1. radioactive particle treats basic conception
Using modern imaging technology will have radioactive nucleic (such as I125) directly transplanting to tumor target volume it is interior or
Around tumour, tumour cell is killed by radionuclide sustained release ray.
2. the damage of Radiation On Human body health (by taking common I125 as an example)
I125 is orbital electron capture decay nucleic, and the energy of γ ray of transmitting is 0.03548 million electro-volt.Half-life period
It is 60.14 days.The I125 of 3.7 × 10 Becquerels weighs 5.76 × 10 grams.The I125 point source of 3.7 × 10 Becquerels is 1 centimetre of distant place
Exposure rate be 0.66 roentgen/when.
In the case of chronic, low dose of long-term irradiation, radioactivity I125 radioactive particle damages more caused by human body
People should be worth to pay attention to.The main aggrieved crowd of chronic radiation injury is medical care and entourage.Most people in them is long
The radiation of the overproof dosage of receiving of time, the crowd for receiving radiation exposure for a long time are to be mainly responsible for the medical care for looking after patient and family
Belong to entourage.Ray can cause human body much to injure, and radiation insult is formed in accumulating over a long period, and be caused to body tight throughout one's life
It damages again.
Ray may cause clinical symptoms to have weak, dizzy, headache, tinnitus, sleep disturbance, failure of memory, hidrosis, the heart
Throb with fear；Secondly it is symptom of digestive tract such as abdominal pain and distension；A few peoples have a toothache, the easy bleeding of gum；Groups of people's easy catching a cold, pain in the back, joint
Ache.
The radiation of Long Term Contact low dosage does not notice that protection can cause skin lesion again, mainly shows skin, the nutrition of nail
Obstacle.
Radiation insult can cause women amenorrhoea, the decline of male and female fertility, female sexual hypoactivity, cataract, anaemia,
Leucocyte and decrease of platelet, autonomic nervous dysfunction, hematopoiesis function be low, lenticular opacities, Spermatogenic failure, even
Induced tumor etc..
The normal illumination being subject to individual should limit.With caused by ensureing the combined illumination by being approved practice from items
The total effective dose of individual and total yield dosage in relation to organ or tissue no more than corresponding agent specified in GB18871-2002
Measure limit value.
3. radiation proof basic skills：Distance protection, protection of time, shielding protection
Distance protection：Distance protection is a kind of effective ways of protection radiation, and increasing human body can have at a distance from radiation source
Effect reduces exposure, according to patient's body implantation radiation population other than 2 meters of the patient it is ensured that entourage
Personal safety to reach protection purpose, but keeps this distance it is difficult to accomplish with the help of patient needs entourage.
Protection of time：The suffered intergal dose irradiated of entourage is directly proportional to the time therefore constant in exposure intensity
In the case of, exposure amount can be reduced by shortening irradiation time, to reach protection purpose.The main points of protection of time are to try to shorten
Time of the entourage within the scope of radiation exposure, reduce the time of exposure.But the half-life period of I125 is 60 days, ray
Prolonged exposure nearly half a year.Obvious protection of time is nor optimal selection.
Shielding protection：Intensity can weaken when ray radiation penetrating material, and certain screening energy, which weakens, is even isolated ray
Intensity, enough screens are arranged between radioactive particle radiation source and entourage can reduce even blocking radiation to accompanying
The injury of shield personnel, it is ensured that the safety of entourage achievees the purpose that protection.The use of lead screen protection is convenience generally acknowledged at present
Effective safeguard procedures.
4. radiation proof national standard
(1)《Radioactive isotope and x-ray apparatus safety and protection regulations》Regulation
The medical and health organization that treatment for radiation-caused disease is carried out using radioactive isotope and radiological unit, should be defended according to State Council
Raw authorities' pertinent regulations and national standard formulate the adaptable Quality assurance programme of the diagnosis and treatment item being engaged in our unit,
Avoid all unnecessary according to the principle of medical exposure justification and optimization of radiation protection in accordance with quality assurance monitoring specification
Irradiation, and inform in advance patient and subject radiation to health potential impact.
(2)《GB18871-2002 ionization radiation protections and the safe basic standard of radiation source》Regulation
Potential irradiation danger suffered by reply individual limits, and uses all potential irradiations for being approved practice from items
Caused individual is dangerous, and health risk corresponding with normal illumination dose limit institute is in same order of magnitude level.
Irradiation for any particular source in a practice should be such that protection is optimized with safety so that considering
After economy and social factor, the size of personal radioactive dose, the number of exposure and the possibility of exposure keep
In the low-level as possible that can rationally reach；This optimization should be respectively lower than with personal dose caused by the source and potential irradiation danger
Dose constraint and potential irradiation danger are constrained to precondition (except therapeutic medical exposure).
For it is any may be to the source of Environment release radioactive substance, dose constraint it is ensured that discharge the source tired over the years
Product effect limits so that consider every other related practice and source may caused by after release accumulates and irradiates,
Any Members of The Public (including its offspring) effective dose suffered in any 1 year is no more than corresponding dose limit.
Control the illuminated of the public.
