Embodiment Construction

[0008] Referring to the accompanying drawings, a medical isotope needle tube protective cover is mainly composed of a body 10 on which a viewing window 20 is provided, and a shielding cap 30 is provided on the upper end of the body 10 . The junction of the shielding cap and the body is provided with an internal thread 40 matching the outer diameter of the needle tube. Due to the shielding effect of the thread, the needle tube can be fixed and the time for the doctor to draw the liquid medicine is shortened, thereby reducing the radiation dose of the doctor, achieving the protection of external radiation by shortening the time of exposure as much as possible and setting the time between the person and the radiation source. The condition of the shield.

Abstract

The invention discloses a fixed protection sleeve of a needle tube, which mainly comprises a body. The body is provided with a squint window, and the upper end of the body is provided with a shielding cap, and the fixed protection sleeve is characterized in that the combined part of the shielding cap and the body is provided with inner threads anastomotic with an external diameter of the needle tube. The sleeve has reasonable structure, and ingenious conception; the shielding cap is used as the shielding between a doctor and the liquid medicament of a needle head so as to reduce the radiant quantity of the doctor; the combined part of the shielding cap and the body is provided with the inner threads, which effectively increases the direct friction force of the needle tube and the protection sleeve, plays a role in fixing the needle tube, reduces the operation time, achieves the conditions of external irradiation protection, namely the irradiated time is shortened as much as possible, and the shielding is arranged between people and a radiation source; and the sleeve embodies the people-oriented spirit, and has great popularization value.

Description

technical field [0001] The invention relates to the technical field of medical containers, in particular to a protective device for extracting medical isotope medicaments. Background technique [0002] In the prior art, manufacturers of isotope medicines first put the radioactive medicines into the vials, then move the vials containing the radioactive medicines into shielded tanks made of lead materials, and transport them to the hospital by manual lifting: then After the medical staff opened the shielding tank, they used a syringe to extract the medicine in the vial in the tank and serve it to the patient. During the extraction process, it is inevitable that a certain dose of radiation will be received. A needle guard is specially used for this purpose. However, in the process of use, one is that the structure of the protective cover is not convenient for the hand to exert force, which will increase the extraction time, and the other is that there is no shielding device b...
