Abstract
The invention discloses a ray shielding and shelter device for medical radiodiagnosis treatment. The device comprises a ray shield cover body, shelter plates arranged at the front end and the bottom end of the ray shield cover body, blank space shelter plates on the upper side and the lower side of the ray shield cover body, a cover body shelter plate at the upper side and the lower side of the ray shield cover body, an arm intervention protection device at the front side of the ray shield cover body, and the like. The device is connected with a move assistant arm through a ray receiving device arranged at the upper side and a ray generating device arranged at the lower side, drives a C-shaped slide rail by rotating a motor and drives the ray shield device to do synchronous rotation movement around an object to be diagnosed so as to achieve the aims of intervening the diagnosed object into the surgery and simultaneously ensuring that the medical personnel cannot be radiated by the ray. The device is a shield cover body formed around the object to be diagnosed, and the parts are closely connected; therefore, the device can effectively shelter the ray in the ray shelter device, and prevent the ray from harming the body and other parts of the diagnosed object.
Description
Technical field
The present invention relates to a kind of alpha ray shield preventer, particularly relate to a kind of clinical position intervention diagnosis and treatment, tumour radiotherapy, X line of being used for and take the photograph in sheet, the perspective process device radiation protection.Belong to the armarium technical field.
Background technology
At present, the radiotherapy of diagnosis, treatment and the tumor that gets involved at home, the application in the outer clinical position is increasingly extensive, be used for diagnosis and treat multiple disease widely in clinical a plurality of section office such as cardiovascular internal medicine, vascular surgery, neurosurgery, Neurology Department, oncology etc., for clinical a lot of difficult and complicated illness provide new treatment approach.In the prior art; in getting involved the diagnosis and treatment process; the most general mode is to adopt screen as the means that the diagnosis and treatment personnel prevented roentgenization; the operating-table next door is established or hung on to this screen; because the protective range of screen is limited; airtight degree is bad; when the diagnosis and treatment personnel carry out intervene operation for the patient; ray is not only implemented irradiation to the patient, has also largely shone the diagnosis and treatment personnel simultaneously, and another kind of mode is that the diagnosis and treatment personnel wear protective clothing on one's body; because protective clothing can only be provided with some protective materials in the part; such as in the shirtfront; back; positions such as shoulder are provided with protective material, thereby protective clothing can only carry out the ray protection to diagnosis and treatment personnel's part.In clinical intervention diagnosis and therapy process,, find that intervention diagnosis and therapy staff ray radioactive dose is very high, considerably beyond national standard through the roentgendosis data monitoring of clinical external exposure.The diagnosis and treatment staff accumulates over a long period owing to often be exposed under the irradiation of ray, has caused for self health and has a strong impact on.In the tumour radiotherapy process, the lonizing radiation of scattering can cause radiological detriment to the body part outside the patient's treatment zone.
In CN 2373874Y, introduced a kind of intervention diagnosis and therapy special-purpose multifunctional X-ray protection lead shield, more existing simple screen shielding has been done to a certain degree and has been improved, but still can not all stop ray, and can stop the motion of ray generating means or ray receiving system to health foot extreme direction.
Summary of the invention
Technical problem to be solved by this invention provides the different scheme of a kind of and described prior art, purpose is to overcome above-mentioned the deficiencies in the prior art, provide a kind of by the shielding of alpha ray shield cover body conduct, to realize a kind of alpha ray shield preventer that is used for the medical radiation diagnoses and treatment to the effective protection of operator and patient in the medical radiation diagnosis and treatment process to ray.The present invention is simple in structure, and is easy for installation, good to the ray protection effect.
A kind of alpha ray shield preventer that is used for the medical radiation diagnoses and treatment of the present invention is achieved through the following technical solutions:

The specific embodiment
The present invention is not subjected to the restriction of following embodiment, can determine concrete embodiment according to technical scheme of the present invention and practical situation.
The heart intervene operation is in the medical radiation diagnoses and treatment multi-faceted multi-angle irradiation to be required the highest operation, and the most frequently used position of operation is by the femoral artery of diagnosis and treatment object, is that example and accompanying drawing are further described the present invention with the heart intervene operation below:
Before describing embodiment, illustrate earlier, head end in the literary composition and foot end be on the operation table by the position of diagnosis and treatment object and fixed, left side and right side be with respect to lie on the back in operation table by for the diagnosis and treatment object, upside and downside are for the normal rest state before the present invention is in work.
The setting of alpha ray shield cover body 1 downside is identical with being provided with of its upside, and it is symmetrical with the cover body protective plate 7 that alpha ray shield cover body 1 upside, ray receiving system prolong the setting of cover 5 both sides that alpha ray shield cover body 1 downside, ray generating means prolong the cover body protective plate 7 that overlaps the setting of 6 both sides.When ray receiving system 3 peripheries are not established the ray receiving system and prolonged cover 4, ray generating means 5 peripheries and do not establish the ray generating means and prolong cover 6, prolong protective plate 8 and be set directly at 3 sides of ray receiving system and sufficient side, 5 sides of ray generating means and sufficient side.
When needs owing to diagnosis and treatment, " C " shape slide rail 16 is along by diagnosis and treatment subject's body Y-direction head end or foot end when mobile, ray receiving system 3 is done oppositely with ray generating means 4 and is moved, the alpha ray shield cover body about in the of 1 the formed radiation protection white space in both sides just in time direction is opposite.When ray receiving system 3 when sufficient extreme direction moves to greatest extent, the cover body protective plate 7 of alpha ray shield cover body 1 upside is that sufficient side is shunk, a side prolongs, ray generating means 4 is the head-end direction and moves to maximum position at this moment, and the cover body protective plate 7 of alpha ray shield cover body 1 downside is that a side is shunk, sufficient side prolongs; And the formed protection of alpha ray shield cover body 1 upside this moment clear area is oppositely corresponding with the formed clear area of downside.
Embodiment 11; as 1; Fig. 4; Fig. 9 and shown in Figure 10; when carrying out intervention diagnosis and treatment operation; when the operating position is selected in by the upper limb of diagnosis and treatment object; can and one arm be set at the alpha ray shield cover body and get involved protector 25 by diagnosis and treatment object shoulder corresponding section; arm is got involved on the protector 25 and is established semi-girder mouth 21; can be stretched out outside the alpha ray shield cover body 1 by semi-girder mouth 21 by diagnosis and treatment object upper limb; arm is got involved on the protector 25 and is set to stacked arc backplate 22; when alpha ray shield cover body 1 under the drive of ray receiving system 3 and ray generating means 4 when being rotated by the diagnosis and treatment object; arc backplate 22 can be stacked or flexible, makes semi-girder 21 keep relative static conditions with alpha ray shield cover body 1 all the time.
