Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of multi-way blood transfusion device.
Background technology
Existing medical multi-way blood exchange transfusion set (see figure 1) comprises blood bag puncture needle 1, saline bottle puncture needle 4, blood transfusion flexible pipe 2, infusion tube 5, three actuators 3,6,10, a tee T 7, a dropping funnel 8, a flexible pipe 9, a venoclysis needle 11, venoclysis needle 11 links to each other with the outfan of dropping funnel 8 by flexible pipe 9, is with actuator 10 on this flexible pipe 9 and can be used as the speed of regulating blood transfusion or transfusion or close flexible pipe 9; Input at dropping funnel 8 is provided with tee T 7, one of in addition two arm of this tee T 7 link to each other with blood bag puncture needle 1 by the blood transfusion flexible pipe 2 that is with actuator 3, constitute the blood transfusion pipeline, another root links to each other with saline bottle puncture needle 4 by the blood bag puncture needle 1 that is with actuator 6, constitutes brine pipeline.In the blood transfusion process, once defeated at least four units of patient, defeated at most more than 20 unit on request, will connect next bag blood with the normal saline washing pipeline of transfusing blood in the middle of the input of different blood donors' blood again.Conventional by blood transfusion, after at first importing saline and determining in blood vessel, brine pipeline actuator 6 cuts out, open blood transfusion pipeline actuator 3 and can transfuse blood, treat after blood in the blood bag is totally lost brine pipeline actuator 6 to open to cut out behind the flushing flexible pipe 9 again to connect second bag of blood.Dropping funnel 8 is made up of dropping funnel kettle 81 and the dropper 82 and the filters 83 that are arranged in the dropping funnel kettle 81, and dropping funnel kettle 81 is generally expected to make with injection moulding or plastic uptake and expressing technique by PVC, has certain elasticity; Dropper 82 is positioned at the upper end of dropping funnel kettle 81, and dropper 82 oozes 20 liquid of bleeding and is about 1ml; Filter 83 is positioned at the bottom of dropping funnel kettle 81, and it is blocked in the impurity in the blood on the filter 83 and the energy blood clean.But, coagulation matters in the blood and impurity can be in the blood transfusion process blocking filter 83, influence transfusion speed even occlude blood and filter, the maneuver of taking usually in clinical is to pinch the perisporium of dropping funnel kettle 81 back and forth, to inflation in the dropping funnel kettle 81 its pressure is increased, to guarantee finishing smoothly of the process of transfusing blood.But because the construction features of existing dropping funnel 8, under the effect of squeeze pressure, this method but makes coagulation matters and impurity see through filter screen with blood easily and flows into human body, influence blood transfusion quality.In addition, often require different fluid infusion velocities in the process of blood transfusion or transfusion, this all is to regulate flow by the sectional area of regulating infusion tube to realize.The most frequently used flexible pipe flow regulator is generally the flow regulator of roller clamp shape, the flexible pipe of this flow regulator is because the very big pressure of being concentrated, " cold flow " phenomenon takes place in hose material easily, be expendable deformation, make the flexible pipe sectional area change, can't obtain stable flow rate, may bring danger to the patient, therefore, propose a kind of flow regulator, comprise a clamping case and a roller bearing, offering one in the clamping case increases the groove that the degree of depth reduces towards the flow direction width, can significantly reduce the danger of cold flow, keep stable fluid infusion velocity.This flow regulator structure more complicated need be at the inner surface processing guide rail of groove, and from the moulding process of working of plastics, mould designs relative complex, and cost is higher.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of double-cavity drop funnel multi-way blood transfusion device is provided, and it can be guaranteed blood quality and make finishing smoothly of blood transfusion process.
The purpose of this utility model is achieved by following technical scheme, a kind of multi-way blood transfusion device, comprise blood bag puncture needle, the saline bottle puncture needle, the blood transfusion flexible pipe, infusion tube, one tee T, one dropping funnel, one flexible pipe and a venoclysis needle, venoclysis needle links to each other with the outfan of dropping funnel by the flexible pipe that is with flow regulator, tee T is positioned at the input of dropping funnel, two arm links to each other with blood bag puncture needle and saline bottle puncture needle by blood transfusion flexible pipe and the infusion tube that is with flow regulator respectively, described dropping funnel comprises the dropping funnel kettle, be arranged on dropper and filter in the dropping funnel kettle, described flow regulator comprises groove shape clamping case, be positioned at flexible pipe and a holder of clamping case, wherein, described dropper is positioned at the middle part of dropping funnel kettle and is connected with the inner wall sealing of dropping funnel kettle and dropping funnel kettle inner chamber is divided into epicoele and as the cavity of resorption of extrusion chamber, described filter is arranged in the epicoele of dropping funnel kettle.The bottom surface of the clamping case cell body of described flow regulator is that semicircle and semicircle diameter are more than or equal to hose diameter, described holder is one and is positioned at the eccentric that vertically is provided with on the flexible pipe, this holder connects two sidewalls of clamping case cell body with lateral shaft, and its minor axis summit contacts with hose surface.
Above-mentioned multi-way blood transfusion device, wherein, the epicoele of described dropping funnel kettle and the length ratio of cavity of resorption are 0.9～1.2: 1.
Above-mentioned multi-way blood transfusion device, wherein, described dropper is a funnel-form, it is to connect by hot pressing that its inner wall sealing with the dropping funnel kettle is connected.
Above-mentioned multi-way blood transfusion device, wherein, described filter is filtering screen or web plate.
Above-mentioned multi-way blood transfusion device, wherein, described eccentric thickness is more than or equal to the diameter of flexible pipe.
Above-mentioned multi-way blood transfusion device, wherein, described eccentric long axis length equals lateral shaft deducts flexible pipe to the distance of clamping case bottom land twice wall thickness.
Above-mentioned multi-way blood transfusion device, wherein, suit one flexible sheath on the described eccentric side face.
Owing to adopted the technical solution of the utility model, in the blood transfusion process, influence flow for guaranteeing that filter screen does not get clogged, can pinch the perisporium of dropping funnel kettle cavity of resorption back and forth, the pressure of dropping funnel kettle cavity of resorption is upwards pushed away, the coagulation matters and the impurity that are deposited on the filter will be broken up by intracavity on the dropping funnel kettle, make filter unimpeded, thereby guarantee dropper amount of dripping and blood cleanliness factor, make coagulation matters and impurity can not flow into human body.Roller with the flow regulator of prior art is changed to eccentric again, utilizes eccentric to rotate and compresses flexible pipe, regulates the flexible pipe cross section and reaches and regulate the flow purpose.The eccentric width is bigger, and compressive plane is bigger, and bottom land is semicircle, and flexible pipe generation cold flow is avoided in effectively dispersive pressure, and a flexible sheath has been adorned in the eccentric outer ring, further improves flexible pipe and concentrates the pressurized situation.Because eccentric uses an axle to fix, and need not to offer guide rail in groove inside, processing is simple, and production cost is low.
