Abstract
The utility model relates to a radionuclide injection and protection device in order to solve the problem that radionuclide injection lacks of a protective means. The radionuclide injection and protection device comprises a tungsten alloy tube body used for being sleeved on an injector needle tube part. The tube body is provided with an axial through hole used for observing the scales of an injector needle tube, a transparent lead glass strip used for absorbing radiating rays is fixedly arranged inside the axial through hole, and the tube body is further provided with a clamping and fixing device used for clamping and fixing the injector needle tube part in a matching mode. The radionuclide injection and protection device has the advantages that when in use, the radionuclide injection and protection device is sleeved in the injector, the radiating rays radiated by the injector to the periphery can be effectively shielded, the clamping and fixing device is used for clamping the injector needle tube part, then extracting, conveying and injecting can be achieved, the scales of extracting and injecting can be observed in real time through the transparent lead glass strip, and using is very convenient.
Description
Technical field
This utility model relates to a kind of radioprotector, particularly relates to a kind of radionuclide injection preventer.
Background technology
At present, the radioactive nucleus essence injecta, such as TC-99 etc., be widely used in targeted therapy, radionuclide imaging etc., but in the injection process syringe is lacked the radiation protection means, so that medical care or experiment operator are exposed under the lonizing radiation of injection medicament for no reason, be subject to unnecessary lonizing radiation injury.
Summary of the invention
This utility model relates to the defects that purpose is to overcome prior art, and a kind of convenient radionuclide injection preventer that uses is provided.
For achieving the above object, this utility model radionuclide injection preventer comprises a tungsten alloy body that is used for suit syringe needle tube portion, described body has for the axially extending bore of observing the syringe needle tube scale, be fixedly mounted with in the described axially extending bore for the transparent lead glass bar that absorbs lonizing radiation, described body also is fitted with for the clamping device that fixes the syringe needle tube portion.Pack into syringe when having use, can the lonizing radiation that syringe is dispersed to periphery effectively be shielded, blocking syringe needle tube portion, extraction, movement, injection with clamping device gets final product, and see through transparent lead glass bar and can Real Time Observation extract and the scale of injection the advantage of very convenient use.
As optimization, described clamping device is be used to the orchid dish clamping device that blocks the blue dish of syringe needle tube base portion.The blue dish of card is compared with card needle tubing body, more can fixedly secure.
As optimization, the rear port that described tungsten alloy body is used for the blue dish of equipped syringe needle tube base portion is shaped with horn mouth.Horn mouth can make the blue dish of syringe needle tube base portion press close to tungsten alloy body rear end.
As optimization, described tungsten alloy body front end is taper, then makes things convenient for injection operation.
As optimization, described body upwards is shaped with axial microscler boss, and described axially extending bore and transparent lead glass bar are arranged on microscler boss place.Conveniently configure on the one hand glass bar, the corresponding increase lead glass bar thickness of possibility guarantees shielding intensity on the other hand.
As optimization, the front portion of described microscler boss and middle part arrange axially extending bore and transparent lead glass bar, described microscler boss rear portion is shaped with the groove for equipped clamp, described groove by the equipped the inner of bearing pin be furnished with support spring, outer end can with the seesaw-type clamp of the blue dish of syringe needle tube base portion buckle.The groove of equipped clamp is set at microscler projection section protruding upward, on the one hand the space is set large, convenient design and equipped can not make because of offering of groove the relative attenuation of body wall thickness at this place on the other hand.Cause the weak district of unnecessary shielding.
As optimization, described clamp middle part is equipped with below bearing pin, the inner and is shaped with the notch that coils for fastening syringe needle tube base portion orchid between the described bottom portion of groove below equipped support spring, the outer end.Press clamp the inner downwards, the clamp outer end is upwards lifted, the blue dish of syringe needle tube base portion is discharged, pick and place flexibly syringe; Unclamp clamp the inner, described notch just can firmly block the blue dish of syringe needle tube base portion.
As optimization, be shaped with the upper blind hole for equipped support spring upper end below described clamp the inner, described bottom portion of groove also is shaped with the corresponding with it lower blind hole that is used for equipped support spring lower end.Blind hole can retrain support spring up and down, can not deviate under normal operating condition, strengthens reliability.
As optimization, described clamp is that the middle part is recessed, two ends upwarp, and the inner or upper surface, interior outer end that upwarps is shaped with the asperities that makes things convenient for hands to touch, very convenient operation.
As optimization, the part of described tungsten alloy body front end except microscler boss is taper, convenient hand steered end.
After adopting technique scheme, this utility model radionuclide injection preventer packs into syringe when having use, can the lonizing radiation that syringe is dispersed to periphery effectively be shielded, blocking syringe needle tube portion, extraction, movement, injection with clamping device gets final product, and see through transparent lead glass bar and can Real Time Observation extract and the scale of injection the advantage of very convenient use.
