Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of infusion flow velocity regulator.
Background technology
Infusion treatment is clinical a kind of critical treatment means, and infusion treatment can be applied to transfusion device or the infusion pump of various dissimilar infusion regulator, to be applicable to different occasions.
The ultimate principle of existing common transfusion actuator is roughly the same, substantially be provided with pulley outside transfusion catheter, mainly through pulley extruded transfusion catheter, its shape is changed, and then changing the cross-sectional area of its fluid course, the cross-sectional area namely by changing transfusion catheter fluid course carrys out regulating transfusion flow velocity.
Common transfusion actuator one-hand operation, the step-less adjustment of infusion flow rate can be realized, but because transfusion catheter is for being with elasticity and ganoid flexible pipe, in infusion process, pulley can be passed from desired location, even push away to complete slippage, make infusion flow rate out of hand, the infusion flow rate exceeding predetermined speed can cause the serious medical accidents such as patient's heart failure, death clinically, forms major safety risks.Clinically by increasing, nursing staff makes an inspection tour, the method for check and correction number of times is also corrected in time to find that infusion flow rate drifts about, harm when avoiding above-mentioned situation to occur, but the method obviously increases nursing staff's workload.
Simultaneously because transfusion catheter exists elasticity and transfusion catheter can deform by after long-time extruding, not resilient, when clinical practice is applied, the non-predictable judgement of fluid course cross-sectional area of transfusion catheter, make operator can not according to pulley position judge transfusion catheter be squeezed after the cross-sectional area size of transfusion catheter, and then can not infusion flow rate be judged, need during each adjustment operator coordinate timer repeatedly artificial nucleus to just reaching desired value, to waste time and energy and error is not larger, increase the workload of nursing staff, especially when clinical transfusion workload is large, increase patient's turn time, delay treatment.The adjustment of the flow experience depending on operator, but not flow regulator itself, when needs accurately control infusion flow rate, cannot apply more.
Existing common discharge setting formula transfusion device adopts and presets cross-sectional area consecutive variations and the fixing fluid course of shape clinically, firm banking liquid outlet is communicated with firm banking inlet by fluid course, different by fluid course cross-sectional area corresponding between firm banking inlet from firm banking liquid outlet, reach the object of regulating transfusion flow velocity.
Flow set formula infusion regulator can realize the step-less adjustment of infusion flow rate, can solve infusion flow rate drift, but complex process, need bimanualness, cost of manufacture is higher, and flow-speed scale curved design ringwise, need manual rotation to observe flow scale, inconvenient nurse patrols transfusion condition.When the high viscosities such as infused blood goods, intravenous nutrition, mannitol or high precipitations degree liquid, because default fluid course cross-sectional area is less and stroke is longer, easily block, therefore be difficult to clinically popularize.
In clinical practice application, single drop volume of different medicinal liquid can be different, is commonly between 0.043 ~ 0.05ml, and specific drugs more exceedes this scope.Existing flow set formula actuator can not meet the change of medicinal liquid list drop volume, therefore during clinical transfusion, and carrying out operation by " dripping " can be more accurate, clinically generally carries out infusion flow rate adjustment by nursing staff with reference to single drop volume of different medicinal liquid.
When needs accurately control infusion flow rate, generally use infusion pump, but infusion pump need use when there being power supply, carries inconvenience, price is high, unfavorable popularization, and operation is too complicated, not intuitively easy.
