Abstract
A continuous micro-infusion device, belonging to the technical field of medical appliances. The infusion apparatus comprises a shell, an infusion pump, a control tube and a joint, and is characterized in that the infusion apparatus is provided with a tee body comprising an injection port, an output port and a sliding rod sleeve. The control tube adopts a multi-cavity special-shaped channel structure and is connected between the output port and the joint. The utility model discloses convenient to use, sanitary safety, flow control is accurate stable.
Description
This utility model is a kind of apparatus of infusing in human body, belongs to technical field of medical instruments.
Existing micro-transfusion device, constitute by shell and infusion pump that places slide bar, jack rod sleeve, transfusion capsule, sealing ring in the shell to constitute and tube for transfusion etc., the transfusion capsule is separately fixed at slide bar and jack rod sleeve end by sealing ring, the infusion pump end is provided with rubber stopper, in infusion pump, inject or during output liquid, all be that entry needle is inserted in the rubber stopper.Existing this transfusion device, the injection of liquid, output all need interim attended operation, promptly have the safe and sanitary problem, the complicated inconvenience of program.Tube for transfusion is garden, a single chamber shape passage, and crooked, the back of pushing, tie a knot is easily stopped up, and easily causes the flow-control inaccuracy.
The purpose of this utility model is that a kind of facility, health, stable lasting micro-transfusion device of flow-control operated will be provided.
The purpose of this utility model is to realize by the improvement to existing transfusion device; continue micro-transfusion device; comprise shell, infusion pump, joint; it is characterized in that transfusion device is provided with three-way body and the multi-cavity abnormity channel capacity control valve that comprises inlet, delivery outlet, jack rod sleeve; an end and shell that three-way body is arranged on shell constitute one; inlet is provided with over cap, and delivery outlet is provided with filter, and jack rod sleeve is provided with steam vent.Said steam vent is arranged on the jack rod sleeve intersection with sealing ring.Inlet, delivery outlet communicate with infusion pump by jack rod sleeve.
This utility model novel and reasonable structure, good integrity is manufactured easily, and cost is low, uses easy to operately, reduces the program of injecting and need inserting injection needle during output, the assurance safe and sanitary.Adopt multi-cavity abnormity channel capacity control valve, not by bending, the influence of extruding, knotting, flow-control accurately, stable.
Accompanying drawing 1 is a structural representation of the present utility model; 1 shell, 2 slide bars, 3 jack rod sleeves among the figure, 4 transfusion capsules, 5 sealing rings, 6 inlets, 7 delivery outlets, 8 over caps, 9 filters, 10 multi-cavities abnormity channel capacity control valve, 11 joints, 12 three-way bodies, 13 fixation clamps, 14 steam vents.
Accompanying drawing 2 is the section structure sketch map of multi-cavity abnormity channel capacity control valve of the present utility model, 15 multi-cavities abnormity passage among the figure.
Narrate case study on implementation of the present utility model below in conjunction with accompanying drawing.
End at shell is provided with three-way body, and promptly three-way body is formed one with jack rod sleeve, inlet, delivery outlet.The intersection of the sealing ring of fixing transfusion capsule is provided with steam vent on the jack rod sleeve, and inlet is provided with check valve and over cap, and delivery outlet is provided with the nuclear pore filter film filter.The channels designs of control valve becomes the multi-cavity polymorphic structure, is connected between delivery outlet and the joint.
