Abstract
A multi-pipeline chemo-treatment infusion pump comprises a base (1), a silastic liquid medicine storing sac (9), a core rod (8), a liquid medicine inlet (3), a transparent pile casing (2), a self-control doser (4), a liquid medicine outlet (5), a perfusion tube (6), a liquid medicine outlet head (13), and current limiting tubes (10). The core rod as well as the liquid medicine storing sac and the pile casing of the core rod are positioned at the middle part of the base; the liquid medicine inlet, the self-control doser and the liquid medicine outlet are positioned on the base arranged at one side of the pile casing; more than two current limiting tubes are positioned in the base arranged at the other side of the pile casing, and the flow resistance of each current limiting tube is different from that of other current limiting tubes; each current limiting tube is respectively connected with a flow rate switch (11) in series and then is connected between the liquid medicine outlet and an inlet of the pile casing in parallel. As a plurality of current limiting tubes with different flow resistances are connected with each other in parallel, the multi-pipeline chemo-treatment infusion pump can adjust the flow rate of liquid medicine within larger range by turning on and off the flow rate switch, thereby satisfying the requirements of different patients.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments that trace continues transfusion, a kind of multitube road chemotherapy infusion pump of being used for.
Background technology
Microinfusion pump is a kind of apparatus that trace continues transfusion that is used for, and is mainly used in trace such as operation back pain relieving, chemotherapy and continues or interrupted administration.Existing microinfusion pump is the one-pipe structure, and flow velocity generally is set at 2.0ml/h, can't regulate, and can not satisfy different patients' needs.
Summary of the invention
This utility model is intended to propose a kind of trace transfusion apparatus of transfusion speed energy flexible, a kind of multitube road chemotherapy infusion pump.
This multitube road chemotherapy infusion pump comprises the medicine storing bag, plug, feeding opening of pedestal, silicone rubber, transparent casing, automatic control drug feeding device, medicine outlet, tube for transfusion, drug head and current limiting tube.Medicine storing bag is the pipe shape, tightly is enclosed within mandrel outer, and the two ends of medicine storing bag are fixed on the two ends of plug, and casing is enclosed within outside plug and the medicine storing bag.There is a passage at the center of plug, and feeding opening has a check valve, and the outlet of check valve is connected with the import of plug.The top of tube for transfusion links to each other with medicine outlet, and the end of tube for transfusion links to each other with the drug head.The import of automatic control drug feeding device links to each other with the import of plug, and the outlet of automatic control drug feeding device links to each other with medicine outlet by an autocontrol switch.Plug and medicine storing bag thereof and casing are positioned at the middle part of pedestal, and feeding opening, automatic control drug feeding device and medicine outlet are positioned on the pedestal of casing one side, and current limiting tube is positioned at the pedestal of casing opposite side.Current limiting tube has more than two, and the flow resistance of every current limiting tube has nothing in common with each other, every current limiting tube respectively and a flow rate switch be in series after again and be connected between the import of medicine outlet and plug.
This multitube road chemotherapy infusion pump can be regulated the flow velocity of medicinal liquid by the opening and closing flow rate switch, thereby satisfy different patients' needs because the connection that is in parallel of the many different current limiting tubes of flow resistance is arranged in a big way.
Description of drawings
Accompanying drawing is the structure chart of this multitube road chemotherapy infusion pump.
The specific embodiment
As shown in the figure, this multitube road chemotherapy infusion pump comprises the medicine storing bag 9, plug 8, feeding opening 3 of pedestal 1, silicone rubber, transparent casing 2, automatic control drug feeding device 4, medicine outlet 5, tube for transfusion 6, drug head 13 and current limiting tube 10.Medicine storing bag 9 is the pipe shape, tightly is enclosed within outside the plug 8, and the two ends of medicine storing bag are fixed on the two ends of plug.Casing 2 is enclosed within outside plug and the medicine storing bag.There is a passage at the center of plug 8.Feeding opening 3 has a check valve, and the outlet of check valve is connected with the import of plug 8.The top of tube for transfusion 6 links to each other with medicine outlet 5, and the end of tube for transfusion links to each other with drug head 13, and the import of automatic control drug feeding device 4 links to each other with the import of plug, and the outlet of automatic control drug feeding device links to each other with medicine outlet 5 by an autocontrol switch.Plug and medicine storing bag thereof and casing are positioned at the middle part of pedestal 1, and feeding opening 3, automatic control drug feeding device 4 and medicine outlet 5 are positioned on the pedestal of casing one side, and current limiting tube 10 is positioned at the pedestal of casing opposite side.Current limiting tube 10 has more than two, is 3 among the figure.The flow resistance of every current limiting tube has nothing in common with each other, and for example, the flow resistance of 3 current limiting tubes is respectively 1.5ml/h, 2.5ml/h, 3.0ml/h, every current limiting tube respectively and a flow rate switch 11 be in series after again and be connected between the import of medicine outlet 5 and plug 8.Rely on the various combination of flow rate switch unlatching and closure state, can obtain 1.5ml/h, 2.5ml/h, 3.0ml/h, 4.0ml/h, 4.5ml/h, 5.5ml/h and 7.0ml/h totally 7 kinds of different medicinal liquid flow velocitys.
When this multitube road chemotherapy infusion pump used, medicinal liquid can pass through the import of feeding opening 3, plug 8, the passage at plug center and a hole on this channel side wall and inject in the medicine storing bag 9, and medicine storing bag is expanded.The elasticity of medicine storing bag makes medicinal liquid keep certain pressure.Open the flow-stopping clip 7 on the tube for transfusion 6, medicinal liquid can be imported in the patient body lentamente by passage, current limiting tube 10, medicine outlet 5, tube for transfusion 6, drug head 13 and the top transfusion needle thereof at plug center.Flow rate switch 11 can only be opened and closed with specific purpose tool by the doctor, and the speed that guarantees transfusion is safety, suitable.Automatic control drug feeding device 4 is to be used in patient's pain unbearably the time, and for example the cancer patient in late period comes the analgesic thereby push the bigger dose of disposable injection voluntarily.A medicine bag, a current limiting tube and an autocontrol switch are arranged in the automatic control drug feeding device, above-mentioned current limiting tube is connected to the front of automatic control drug feeding device medicine bag, because the restriction of this current limiting tube, medicinal liquid in the medicine bag need just can be full of through the sufficiently long time, for example 15 minutes, the volume of this medicine bag also is limited to a rational numerical, 0.5ml for example, and the maximum of automatic control dosing is 0.5ml/ time * 4/h just.When patient pushed automatic control drug feeding device 4 voluntarily, autocontrol switch was opened simultaneously, and the medicinal liquid in the medicine bag of automatic control drug feeding device is just injected in the patient body apace.
As shown in the figure, this multitube road chemotherapy infusion pump can also comprise a plug guide rod 12, the base wall of one end of plug and casing one end fixes, the other end of plug is unsettled, one end of plug guide rod and the free end of plug fix, and the other end of plug guide rod is fixed on the base wall of the casing other end.This structure can make plug fixing firm in pedestal.
