Description

Nuclear medicine ionizing radiation protection finger stall
Technical Field
The utility model relates to a finger stall technical field, concretely relates to nuclear medicine ionizing radiation protects finger stall.
Background
When a nuclear medicine worker disposes, dispenses, manages and injects the radioactive medicines, the human body is irradiated by the radiation from the radioactive medicines, wherein the hands of the human body are most frequently contacted with the radioactive medicines, particularly, the fingers of the human body are almost directly contacted with the radioactive products, and the radiation dose is also the largest. Excessive radiation exposure can cause radiation damage to the tissue or organ of the worker. Therefore, to protect the hands of nuclear medicine personnel, the nuclear medicine personnel (especially pharmacists) need to wear protective gloves to reduce the radiation damage of the rays. The protective gloves in the current nuclear medicine application have the defects of poor shielding effect, heaviness, inflexibility, influence on field operation and the like, so that workers are unwilling to wear the protective gloves. In addition, the protective gloves used at present are not designed for enhancing the protection of the finger tip part, the radiation dose generally received by the finger tip part is most prominent, and related researches show that the radiation dose of the finger tip part can be more than 5 times of that of other parts of a finger, so that the finger tip part is not effectively protected.
SUMMERY OF THE UTILITY MODEL
To the defect that exists among the prior art, the utility model aims to provide a can improve the radiation protection level that nuclear medicine staff pointed each position, the nuclear medicine ionizing radiation protection finger stall of flexibility and comfort level that the staff pointed when improving the operation radiopharmaceutical.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
in order to solve the technical problem, the utility model discloses a nuclear medicine ionizing radiation protection finger cover, including the cover body and shielding layer, the shielding layer sets up in the inside of the cover body, and the thickness of shielding layer reduces from the fingertip to pointing the root in proper order, and the material of shielding layer is high-density silica-based polymer-tungsten combined material.
Optionally, the shielding layer is provided with a groove, and the groove is located at a position of the shielding layer facing the finger joint.
Optionally, the sleeve body comprises a finger tip part and a finger root part, and the finger tip part is in a circular barrel shape; the finger root is semicircular and annular, and faces to the palm side of the finger.
Optionally, the sheath and the shield are manufactured integrally.
Optionally, the shield layer completely covers the inner surface of the finger tip portion.
Optionally, the thickness of the shielding layer on the inner surface of the finger tip portion decreases from the palm side to the back side.
Optionally, the nuclear medicine ionizing radiation protection finger cover further comprises a binding belt, and the binding belt is connected to the end part of the finger root part, which is far away from the finger tip part.
The beneficial effects of the utility model reside in that: the utility model provides a nuclear medicine ionizing radiation protection finger cover, because the shielding layer sets up in the inside of the cover body, the thickness of shielding layer reduces from the fingertip to the finger root in proper order, has strengthened the protection to the finger position, can effectively reduce the radiation dose of radiopharmaceutical to the hand; the shielding layer is made of a high-density silicon-based polymer-tungsten composite material, the high-density silicon-based polymer-tungsten composite material is good in linear shielding effect, has appropriate flexibility and mechanical properties, is convenient for fingers to operate flexibly when being used as finger sleeves, and has good practicability.
Drawings
Fig. 1 is a cross-sectional view of a nuclear medicine ionizing radiation protection finger stall provided in an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the drawings and the following detailed description.
As shown in fig. 1, the nuclear medicine ionizing radiation protection finger stall of this embodiment includes cover body 1 and shielding layer 2, and shielding layer 2 sets up in the inside of cover body 1, because the palm of the hand side of finger is mainly touching the radiation article, and the radiation of palm of the hand side is stronger, therefore the internal surface of the cover body 1 of palm of the hand side all is provided with shielding layer 2. The thickness of the shielding layer 2 is reduced from the finger tip to the finger root in sequence, the shielding layer 2 is made of a high-density silicon-based polymer-tungsten composite material, the high-density silicon-based polymer-tungsten composite material is good in linear shielding effect and has appropriate flexibility and mechanical properties, and the finger can be flexibly operated when being conveniently worn on a finger sleeve.
It is worth noting that the shielding layer 2 is provided with a groove 3, and the groove 3 is located at a position of the shielding layer 2 facing the finger joint. The groove 3 can improve the flexibility of the finger stall in use. The thinnest joint at the joint part can be kept to meet the using function.
Further, the glove body 1 of the present embodiment includes a finger tip portion 11 and a finger root portion 12, and the finger tip portion 11 is in a circular barrel shape; the base 12 is semicircular, and the base 12 faces the palm of the finger. That is to say, under the condition that the palm side has shielding layer 2, the other joints of the finger near the back of the hand can be protected by the shielding shadow without any shielding object or made of a material with good stretching and comfort functions, so that the flexibility of the finger stall can be kept. It is to be noted that the shielding layer 2 completely covers the inner surface of the finger tip portion 11. The thickness of the shielding layer 2 on the inner surface of the fingertip portion 11 is reduced in the order from the palm side to the back side.
Furthermore, the sheath body 1 and the shielding layer 2 are integrally manufactured, namely, the high-density silicon-based polymer-tungsten composite material is adopted.
Certainly, when the finger-root portion 12 is in a semicircular shape, the nuclear medicine ionizing radiation protection finger stall further comprises a binding belt, the binding belt is connected to the end portion, away from the finger-tip portion 11, of the finger-root portion 12, and the finger stall can be tightly worn on a finger by the aid of the soft binding belt.
The thickest part of the shielding layer 2 of the present embodiment corresponds to 137 The lead equivalent of the Cs radioactive source reaches 0.35mm, and can be used for treating 99m The gamma ray generated by Tc is reduced by 58 percent, the lead equivalent at the thinnest part is 0.15mm, and the lead content of the lead can be reduced by 99m The reduction of gamma ray production by Tc is 31%The finger protection device can effectively protect the part of the finger contacting with the radioactive drug, and reduce the radiation dose of the finger of a person caused by the radioactive drug rays.
The device of the present invention is not limited to the embodiments of the specific embodiments, and any person skilled in the art can obtain other embodiments according to the technical solution of the present invention, which also belongs to the scope of the technical innovation and protection of the present invention.
