Description
Technical field
The utility model relates to medical instruments field more particularly to a kind of medicine injection device in nuclear medicine.
Background technique
Currently, medicine injection device in nuclear medicine, that is, ordinary syringe used in clinically, drug used in nuclear medicine has mostly
There is radiativity, in aspiration medicinal liquid, drug easily adheres to needle surface, and in injection, drug is easily sticked on patient skin,
Patient skin is caused greatly to injure, increases great work difficulty to medical worker.Also, giving patient injection drug
When, it needs that a small amount of drug in syringe is released syringe needle in advance in advance, the gas in syringe needle is emptied, prevents from having in syringe needle
Gas, and the drug adhesion released also can cause greatly to injure on syringe needle to the skin of patient.
Utility model content
The purpose of this utility model is to provide a kind of medicine injection device in nuclear medicine, prevent from adhering to radiativity drug on syringe needle.
A kind of to achieve the above purpose, the technical solution of the present invention is: medicine injection device in nuclear medicine, including supervisor, supervisor
One end be communicated with syringe needle, looped pipeline is equipped in supervisor, is communicated with medicinal cupping on looped pipeline, control drug stream is equipped between medicinal cupping and looped pipeline
The tube wall of dynamic first switch, looped pipeline is equipped with liquid outlet, and second that control drug flowing is equipped between liquid outlet and looped pipeline opens
It closes, slidably connects auxiliary piston in looped pipeline, auxiliary piston bar, the one end of auxiliary piston bar far from auxiliary piston are fixedly connected on auxiliary piston
It is fixedly connected with the first magnet block, the block that can be offseted with the first magnet block, block position are fixedly connected on the inner wall of supervisor
In side of first magnet block far from auxiliary piston, main piston, main work are slidably connected between the inner wall of supervisor and the outer wall of looped pipeline
It is fixedly connected with main piston rod beyond the Great Wall, main piston rod is located at outside supervisor far from one end of main piston, and main piston rod is far from main work
One end of plug is fixedly connected with push plate, and second magnet block opposite with the first magnet block magnetism is fixedly connected on main piston rod,
Second magnet block is between the first magnet block and push plate.
The working principle of this programme are as follows: for holding radiativity drug in medicinal cupping, first switch is for controlling in medicinal cupping
Whether drug enters in looped pipeline.Second switch is used to control whether the radiativity drug in looped pipeline to flow out from liquid outlet.Because of master
Piston is slidably connected between the outer wall of looped pipeline and supervisor's inner wall, therefore main piston is close to the side of syringe needle, the inner wall of supervisor and pair
Medicinal liquid cavity can be formed between the outer wall of pipe, consequently facilitating holding non-radiation type drug in medicinal liquid cavity.First magnet block and second
The magnetism of magnet block on the contrary, therefore the first magnet block and the second magnet block can attract each other, when pushing main work by main piston rod
When plug sliding, the second magnet block can push the first magnet block, to push auxiliary piston bar mobile, then be pushed by auxiliary piston bar
Auxiliary piston slides in looped pipeline, the drug in looped pipeline is released from liquid outlet into medicinal liquid cavity, with the non-radiation type in medicinal liquid cavity
Drug mixing, is then flowed out by the promotion of main piston out of syringe needle, together again to be injected into patient.
When by adopting the above technical scheme, since the drug of radiativity is contained in medicinal cupping, when needing to pour into radiation in looped pipeline
Property drug when, first switch is opened, second switch is closed, and main piston rod is pulled, and main piston rod passes through the first magnet block and the
The attracting drive auxiliary piston bar of two magnet blocks slides in looped pipeline, so that the drug in medicinal cupping is drawn into looped pipeline.Radiativity
Drug will not be entered directly in looped pipeline by syringe needle, thus when fundamentally solving syringe needle extraction radiativity drug, radiation
Problem of the property drug adhesion on syringe needle.It is non-radiation type drug due to being held in medicinal liquid cavity, therefore the gas being discharged in syringe needle
When, the drug that flows out from syringe needle is non-radiation type drug, thus prevent that the drug flowed out from syringe needle from being radiativity drug and
It is adhered on syringe needle.To sum up, this programme makes that radiativity drug will not be adhered on syringe needle, so as to avoid the skin for being adhered to patient
On skin, convenient for operation.
Further, first switch includes the first plate and drug-feeding tube, and drug-feeding tube is connected between medicinal cupping and looped pipeline, drug-feeding tube
Tube wall be equipped with first through hole, the first plate is slidably connected in first through hole.When the first plate is inserted into drug-feeding tube,
And when offseting with the inner wall of drug-feeding tube, drug-feeding tube is plugged, and drug will not flow between medicinal cupping and looped pipeline, at this moment first switch
It is in off state.When having gap between the first plate and drug-feeding tube, drug can flow between medicinal cupping and looped pipeline, and at this moment the
One switch is in an open state.
Further, second switch includes the second plate, and the tube wall of looped pipeline is equipped with the second through-hole, and the second plate is slidably connected
In the second through-hole, the second plate can be inserted in liquid outlet.When the second plate is extracted from liquid outlet, liquid outlet and medicinal liquid cavity
It is connected to, the drug in looped pipeline can be flowed out by liquid outlet, and at this moment second switch is in an open state, when the second plate is inserted into out liquid
When in mouthful, liquid outlet is blocked by the second plate, and the drug in looped pipeline will not be flowed out from liquid outlet, and at this moment second switch is to close shape
State.
Further, rubber layer is equipped on the outer wall of the first plate and the second plate.Rubber layer has certain leakproofness,
Prevent gap outflow of the drug between the gap or the second through-hole and the second plate between first through hole and the first plate.
Further, one end and the second plate far from drug-feeding tube of the first plate are equipped with pressing board far from one end of looped pipeline.It presses
Plate increases the contact area of the first plate and the second plate, and operator's hand is facilitated to put forth effort, convenient for sliding the first plate and
Second plate.
Further, anti-skid chequer is equipped on push plate and pressing board.Anti-skid chequer increases between push plate and hand and pressing board and hand
Frictional force between portion operates convenient for medical worker.
