Description

Disposable Radiotherapy chemotherapy infusion apparatus

Technical field

The utility model relates to medical instruments field, especially a kind of disposable Radiotherapy chemotherapy infusion apparatus.

Background technique

Traditional disposable precision filter infusion set, in clinical transfusion, Radiotherapy chemotherapy drug is because irritation is strong, warp Often occur patient vessel redden, blackening, or even there is dark brown, cause the drugs such as fluorouracil, Noviburn in infusion process Appearance blocks and infusion cannot be made to go on, and makes troubles to patient's treatment.

Radiotherapy and chemotherapy medicine infusion apparatus is in infusion, due to particle damage patient vessel's inner wall, when dripping of irritant drugs passes through The blood vessel of damage, causes patient vessel to turn black, or even blood vessel blockage phenomenon occurs, increases great work to nursing staff Bear, when exhaust occur unsmooth for infusion apparatus, can not the things such as automatic liquid-stopping occur, and increase the stress of nursing staff, There must be a kind of specialized transfusion system when therefore, to Radiotherapy chemotherapy medication infusion.

Disposable precision filter infusion sets all at present often will appear when Radiotherapy chemotherapy clinical drug is infused Following situation:

(1) it is vented unsmooth；

(2) it is vented with finger bomb tube wall；

(3) traditional round precise filtering device is tilted 45 degree of exhausts or is inverted and be vented；

(4) traditional round precise filtering device is placed on infusion apparatus bottom, make the residual air that cannot exclude into Enter patient's human body, causes the injury to patient；

(5) worry about air enters human body, and medical fluid is not finished all and just pulls out intravenous needle, therefore therapeutic effect is not achieved, Cause liquid waste；

(6) it after air enters traditional round precise filtering device, not can be carried out second of exhaust, can only give again again Patient punctures infusion, when inputting Radiotherapy chemotherapy medicine, tradition round filter device is blocked due to particle and is forced to stop infusion, again Have to puncture to patient again again and be infused；

(7) it sometimes because nursing not in time or having forgotten to pull out the intravenous needle of patient on hand, causes to admit air into after medical fluid stream is complete In human body, blood vessel blood back is caused to bring injury to patient, therefore increase stress to nursing staff, while patient being caused to fear Unbearably；

(8) Radiotherapy chemotherapy patient causes patient vessel's damage serious, only once exhaust is can not to drain due to being often infused Air in net filter device, the air bubble not being discharged enter human body and directly damage to patient；

(9) in infusion, because medicine irritation is strong, above-mentioned each all directly causes to hurt radiotherapy and chemotherapy medicine to patient Evil.

In view of the foregoing, overcome the defects of above technology, the new infusion apparatus of one kind is provided and is urgently solved as this field Certainly the technical issues of.
