Description
Technical field
This utility model relates to medical instruments field, particularly relates 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, it is substantially and is externally provided with pulley at transfusion catheter, main by pulley extruded transfusion catheter, its shape is made to change, and then change the cross-sectional area of its fluid course, i.e. regulate infusion flow rate by changing the cross-sectional area of transfusion catheter fluid course.
Common transfusion actuator one-hand operation, the step-less adjustment of infusion flow rate can be realized, but owing to transfusion catheter is the elastic and ganoid flexible pipe of band, in infusion process, pulley can be elapsed from setting position, even push away to slipping completely, make infusion flow rate out of hand, infusion flow rate beyond 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 with discovery infusion flow rate drift and is corrected in time, it is to avoid harm when above-mentioned situation occurs, but the method substantially increases nursing staff's workload.
Can deform simultaneously as transfusion catheter exists after elasticity is extruded for a long time with transfusion catheter, 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 infusion flow rate can not be judged, need operator to coordinate timer repeatedly artificial nucleus to just reaching desired value when adjusting every time, waste time and energy and not error bigger, increase the workload of nursing staff, especially clinical transfusion workload is big when, increase patient's turn time, delay treatment.The more experiences depending on operator of regulation of flow, rather than flow regulator itself, needs accurately control infusion flow rate when, it is impossible to application.
The most existing common discharge sets the fluid course that formula transfusion device uses default cross-sectional area consecutive variations and shape to fix, 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 to regulate the purpose of infusion flow rate.
Flow set formula infusion regulator can realize the step-less adjustment of infusion flow rate, it is possible to resolve infusion flow rate drifts about, but complex process, needing bimanualness, cost of manufacture is higher, and flow-speed scale curved design ringwise, need manual rotation can observe flow scale, it has not been convenient to nurse patrols transfusion condition.When the high viscosities such as infused blood goods, intravenous nutrition, mannitol or high precipitation degree liquid, because presetting, fluid course cross-sectional area is less and stroke is longer, easily blocks, therefore is difficult to clinically popularize.
In clinical practice is applied, single drop volume of different medicinal liquids 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, carrying out operation by " dripping " can be the most accurate, and clinical universal single drop volume by the different medicinal liquids of nursing staff's reference carries out infusion flow rate regulation.
When needs accurately control infusion flow rate, it is common to use infusion pump, but infusion pump need to use in the case of having power supply, carries inconvenience, and price is high, unfavorable popularization, and operation is excessively complicated, directly perceived not easy.
