Description
Technical field
This utility model belongs to technical field of medical instruments, is specially a kind of security protection transfusion device.
Technical background
Transfusion is that hospital cures the disease important means, and when carrying out venous transfusion to patient at present, a large amount of use disposable transfusion devices, like this to preventing cross infection from serving certain effect, but also exists a lot of potential safety hazard.
1. existing transfusion device relies on atmospheric pressure transfusion, need constantly in infusion bottle, to supplement air, air floats to ullage through medicinal liquid in the form of bubbles, but in this special environment of hospital, in air, pathogenic microorganism kind is many, the air of band antibacterial passes through medicinal liquid, medicinal liquid has become air filtration liquid, aerial dust and antibacterial have all incorporated in liquid, and patient have input this liquid tend being subject to severe contamination and occurs untoward reaction, even cross infection occurs.
2. current, clinically carrying out patient needing in infusion process to monitor the liquid level in transfusion device, if after infusion-completed not in time process can cause blood back situation, serious words can cause air to enter vein blood vessel, form air embolism.This had both increased the weight of nursing staff and patient's physical load, also precipitate psychosocial burden.
3. Chinese population is numerous, and number of patients radix is large.In external each lesion, the ratio of nurse and sick bed is (1 ~ 1.5): 1, and China is 0.4: 1, and nursing staff works heavy, transfusion drip speed calculates by artificial, not only requires great effort but also time-consuming, changes when dripping speed and not easily finds, easily there is nursing error, produce nurse-patient conflict.
What 4. existing disposable transfusion device generally adopted drip fast actuator is by support body and be arranged on slidable regulating wheel in support body inside groove and form.Because support body is that ramp structure and tube for transfusion smoother make regulating wheel easily loosen, cause dripping speed change; In addition, it is open for dripping fast actuator, and the normal patient of generation and family members regulate for various reasons voluntarily drips speed, and some medicine or disease need the strict speed that controls to drip, otherwise easily produces untoward reaction and be difficult to forecasting consequence.
5. after existing disposable transfusion device uses, outside puncture needle is exposed to, easily stab nursing staff or other people, the whole world has the nursing staff of about 1,000,000 that needle stick injuries accident occurs every year according to statistics, causing more than 20 to plant disease to I haven't seen you for ages, is one of Major Risk Factors causing nursing staff's occupational injury.
6. the needle handle of existing disposable transfusion device and puncture needle are at grade, during use, two refer to grip up and down at needle handle, have finger due under needle handle, puncture needle and skin angle are comparatively large, and after puncture, fixing needle handle presses down, change the direction that puncture needle is original, easily cause puncture needle to wear out blood vessel, some nursing stafves puncture direction at needle handle underlay cotton balls originally in order to keep, but can increase the unstability of puncture needle like this, moreover existing needle handle also not easily holds and exerts oneself, operation inconvenience.
7. commonly use adhesive plaster to the fixing of puncture needle during transfusion at present, because adhesive plaster is flexible, immobilization with adhesive tape puncture needle poor effect, particularly child's movability, often make puncture needle rolling puncture blood vessel wall and cause intravenous extravasation phenomenon or puncture needle to come off.
