Abstract
The utility model discloses a novel transfusion device. The device comprises a dropper, a flow-velocity regulator, a liquid medicine filter and an intravenous needle which are connected sequentially by hoses, wherein two bottle stopper puncture devices are connected on the upper side of the dropper, and hoses connected with the bottle stopper puncture devices and the dropper are provided with switching valves; a cylindrical tube stopper is arranged in the dropper, and is integrally formed by a first tube body positioned on the upper part and a second tube body positioned on the lower part; the diameter of the first tube body is more than that of the second tube body; an annular plate body is sleeved on the upper part of the first tube body; the diameter of the second tube body is the same as that of the liquid outlet of the lower part of the dropper. According to the transfusion device, the cylindrical tube stopper is arranged in the dropper, the tube stopper floats in the dropper under supporting of the annular plate when liquid is filled in the dropper, and the dropper can drip normally; when the dripping process is completed, the liquid level in the dropper gradually falls, the second tube body is inserted into the liquid outlet on the lower part of the dropper, and the liquid outlet of the dropper is closed, so that air is effectively prevented from entering human veins through a hose, and the use is safe.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of transfusion device.
Background technology
Intravenous injection be clinical in aftertreatment mode commonly used, postoperative a lot of patients are owing to taking food, and need a large amount of nutrient of injection, so the patient need to inject a plurality of transfusion bottles every day.In intravenous injection, the patient is more, and, in the less situation of nurse on duty, the nurse often need to run here and there as the patient changes transfusion bottle, works very arduous.Once, for the patient changes not in time, after air enters vein, along vein, at first be brought to right atrium, then enter right ventricle, along with heartbeat, make air and blood be mixed into cystose, and arrive whole body with blood circulation.If air enters pulmonary artery, can block its branch, blood can not be entered in lung, cause severe depletion of oxygen and cause death.
The utility model content
The purpose of this utility model is to provide a kind of novel transfusion device, and this transfusion system structure novelty is easy to use.
To achieve these goals, the technical solution of employing is this utility model:
Novel transfusion device, comprise the dropper, flow regulator, liquid medicine filter and the intravenous needle that connect successively with flexible pipe; Described dropper top is connected with two bottle plug puncture units, on the flexible pipe that bottle plug puncture unit is connected with dropper, is provided with switch valve; The cylindrical tubes plug is housed in described dropper, pipe close is one-body molded with the second body that is positioned at bottom by superposed the first body, the diameter of the first body is greater than the second body, and the top cover of the first body has the lamellar body of annular, and the diameter of the second body is identical with the liquid outlet diameter of dropper bottom.
Preferably, the top of described the second body cover has sealing ring, and sealing ring contacts with the first body.
Preferably, the diameter of described the second body is 0.5 centimetre.
The beneficial effects of the utility model are:
This kind of novel transfusion device can connect two transfusion bottles simultaneously, and complete when the injection of a certain transfusion bottle, the patient can the MTS valve, opens another transfusion bottle and is injected, and has injection in time, easy to operate, can effectively reduce nurse's workload.
The cylindrical tubes plug is housed in dropper, and while in dropper, liquid being arranged, pipe close, under the holding of the lamellar body of annular, floats in dropper, the normal dropping liquid of dropper.Complete when the dropping liquid process, in dropper, liquid level descends gradually, and the second body inserts the liquid outlet of dropper bottom, and by the sealing of the liquid outlet of dropper, effectively the resistance air enters human vein along flexible pipe, uses very safe.
The accompanying drawing explanation
Fig. 1 is the partial structurtes schematic diagram of novel transfusion device.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is elaborated:
In conjunction with Fig. 1, novel transfusion device, comprise the dropper 1, flow regulator, liquid medicine filter and the intravenous needle that connect successively with flexible pipe.Described dropper 1 top is connected with two bottle plug puncture units 2, on the flexible pipe that bottle plug puncture unit 2 is connected with dropper 1, is provided with switch valve 3.In described dropper 1, cylindrical tubes plug 4 is housed, pipe close 4 is one-body molded with the second body 42 that is positioned at bottom by superposed the first body 41, the diameter of the first body 41 is greater than the second body 42, the diameter that lamellar body 5, the second bodys 42 that annular is arranged are overlapped on the top of the first body 41 is identical with the liquid outlet diameter of dropper 1 bottom.
The top cover of described the second body 42 has sealing ring 6, and sealing ring 6 contacts with the first body 41.The diameter of described the second body 42 is 0.5 centimetre.
This kind of novel transfusion device can connect two transfusion bottles simultaneously, and complete when the injection of a certain transfusion bottle, the patient can the MTS valve, opens another transfusion bottle and is injected, and has injection in time, easy to operate, can effectively reduce nurse's workload.
The cylindrical tubes plug is housed in dropper, and while in dropper, liquid being arranged, pipe close, under the holding of the lamellar body of annular, floats in dropper, the normal dropping liquid of dropper.Complete when the dropping liquid process, in dropper, liquid level descends gradually, and the second body inserts the liquid outlet of dropper bottom, and by the sealing of the liquid outlet of dropper, effectively the resistance air enters human vein along flexible pipe, uses very safe.
Certainly; above-mentioned explanation is not to restriction of the present utility model; this utility model also is not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
Claims (3)
