Abstract
The invention relates to a liquid-leaking protecting mechanism of a portable liquid delivery pump. The liquid-leaking protecting mechanism is composed of a pump body, a medicine box, a torsion spring and a contact, the pump body can be mounted on or demounted from the medicine box, the torsion spring is mounted on the medicine box, one end of the torsion spring which is fixed is a torsion spring fixed end, a body portion of the torsion spring is limited by a rotary shaft of the medicine box, the other end which is a torsion spring rotating end can rotate freely around the rotary shaft, the torsion spring rotating end is blocked by a limiting retaining plate of the medicine box in a rotating path to form a clamping mechanism, and the contact is mounted at the torsion spring rotating end. By the liquid-leaking protecting mechanism, the defect of liquid leaking caused by accidental shedding of medicine boxes of existing portable liquid delivery pumps is overcome, and safety of the existing portable liquid delivery pumps is greatly improved.
Description
Affiliated technical field
The present invention relates to infusion pump in medical application, especially the leakage protection mechanism of portable infusion pump.
Background technology
Infusion pump in medical application is usually used in medicine or medicament are injected in patient body.Leakage is a kind of common risks of infusion pump, when leakage occurs, can cause the excessive infused drug of patient or blood back, entail dangers to patient life even when situation is serious.Common infusion pump adopts creeping device extruding elastic transfusion pipe to complete transfusion, and work process Elastic pipe is clamped between creeping device and extruding baffle plate.The extruding baffle plate is installed on openable door closure usually, or makes the part of the medicine box that can separate.Once in this process, door closure is opened by accident or the medicine box accidental, and leakage will occur.The bedside infusion pump generally all is furnished with the automatic liquid-stopping clamp mechanism on the creeping mechanism side, and when door closure comes off, liquid stopping clamp mechanism will clamp tube for transfusion and prevent leakage.Press from both sides, common liquid stopping clamp just is provided on tube for transfusion with medicine box and the various portable infusion pumps that are widely used at present are subject to spatial limitation not design this automatic liquid-stopping.Because the folding of common liquid stopping clamp needs manually-operated, like this once the medicine box accidental or in transfusion because maloperation is taken off leakage will be occurred by accident.On the other hand, if when transfusion forget the liquid stopping clamp of opening on tube for transfusion also can occur can't infusion fault.
Summary of the invention
Cause the deficiency of leakage in order to overcome existing portable infusion pump medicine box (or with the transfusion consumptive material that pushes baffle plate) accidental, the invention provides a kind of leakage protection mechanism, this mechanism design, on medicine box, is driven by a torsion spring.Packing into, this mechanism is in clamped condition after the elastic transfusion pipe, and after medicine box is installed to the pump housing, this mechanism unclamps automatically, and infusion can normally carry out.Once the medicine box accidental, this mechanism Automatic-clamping immediately prevents in the dead of night.Whole process is without manually-operated.The introducing of this leakage protection mechanism, the safety that can greatly improve existing portable infusion pump coordinates the medicine box of suitably design just can realize because this leakage protection mechanism only needs a torsion spring simultaneously, and cost is very cheap.The portable infusion pump that uses this mechanism without manual intervention, operates also very convenient due to the protection process.
The technical solution adopted for the present invention to solve the technical problems is:
The leakage protection mechanism of portable infusion pump, described leakage protection mechanism is comprised of the pump housing, medicine box, torsion spring, contact.Medicine box can be loaded onto or pull down to the described pump housing.Described torsion spring is arranged on medicine box, and an end is fixedly the torsion spring stiff end, and the torsion spring body part is limited by a rotating shaft feature of medicine box, and the other end is that torsion spring rotation end can freely rotate around the shaft.Described torsion spring rotates end to be stopped by the postive stop baffle feature of medicine box in rotation path, forms clamp mechanism.Described contact is arranged on described torsion spring and rotates end.
During use, the elastic transfusion pipe is installed between the postive stop baffle feature of torsion spring rotation end and medicine box.Now clamp mechanism can guarantee that the elastic transfusion pipe is clamped.
When medicine box is loaded onto the pump housing, contact is pushed by the pump housing, makes torsion spring rotate end and rotates, and clamp mechanism discharges the elastic transfusion pipe, now can normal infusion.
When the medicine box accidental, contact is no longer pushed by the pump housing, and torsion spring rotates end and resets, and clamp mechanism clamps the elastic transfusion pipe, and now can guarantee can leakage for clamping force.
The invention has the beneficial effects as follows, overcome the deficiency that existing portable infusion pump medicine box accidental causes leakage, the safety that has improved greatly existing portable infusion pump.Because this leakage protection mechanism only needs a torsion spring, coordinate the medicine box of suitably design just can realize, cost is very cheap simultaneously.The leakage of this mechanism protection action is without manual intervention, easy to operate in addition.
