Description

A kind of continuous infusion set
Technical field
This utility model belongs to the medical sanitary apparatus field, is specifically related to a kind of infusion set of transfusion continuously of realizing.
Background technology
Venous transfusion is a kind of method of common treatment disease, and vein treatment is a kind of wound property treatment that has, and the carelessness of any link all might cause certain injury to patient in medical personnel's operation.China's patient infusion therapeutic dose of seeking medical advice at present is big, and medical personnel are manual operations when giving patient infusion mostly, and the manual medicine bottle of changing generally will be failed two bottles during patient infusion at least, and this has just brought certain trouble to transfusion; In addition, the time generally regulate by rule of thumb in transfusion and to drip speed, not also inaccuracy of science.
The utility model content
The technical problem that this utility model will solve provides a kind of continuous transfusion that realizes, and transfusion the time can be controlled an infusion set that drips speed automatically.
In order to solve the problems of the technologies described above; This utility model provides a kind of continuous infusion set; Comprise infusion bottle, perforator, transfusion catheter, Mo Feishi dropper; It is characterized in that: also comprise float-controlled valve, drip switch, level detection pipe and step motor control flexible pipe, the lower end of said float-controlled valve connects through transfusion catheter successively, and drip switch is arranged on the one section transfusion catheter that connects per two float-controlled valves; Said transfusion catheter is connected with a level detection pipe through the pipeline connector, and level detection pipe lower end connects the Mo Feishi dropper, is connected with the step motor control flexible pipe in said Mo Feishi dropper lower end.
Said step motor control flexible pipe is provided with the transfusion pipe clamp.
Said float-controlled valve comprises valve port, lower valve port and Flat valve core, and said Flat valve core is arranged in the valve pocket that forms between valve port and the lower valve port.
This utility model once can connect a plurality of infusion bottles, and simple in structure, the practicality that saves time, and has reduced nurse's workload, has increased the safety of transfusion; Through the step motor control transfusion speed, make infuse science and hommization more.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done further detailed explanation:
Fig. 1 is the structural representation of a kind of continuous infusion set of this utility model.
Among the figure: 1 infusion bottle; 2, float-controlled valve; 3, perforator; 4, transfusion catheter; 5, drip switch; 6, pipeline connector; 7, level detection pipe; 8, Mo Feishi dropper; 9, step motor control flexible pipe; 10, transfusion pipe clamp; 11, go up valve port; 12, lower valve port; 13, Flat valve core.
The specific embodiment
As shown in Figure 1, the preferred float-controlled valve quantity of present embodiment is three.A kind of continuous infusion set that this utility model provides comprises infusion bottle 1, float-controlled valve 2, perforator 3, transfusion catheter 4, drip switch 5, pipeline connector 6, level detection pipe 7, Mo Feishi dropper 8, step motor control flexible pipe 9 and transfusion pipe clamp 10.The lower end of said three float-controlled valves 2 connects through transfusion catheter 4 successively; Drip switch 5 is arranged on the one section transfusion catheter that connects per two float-controlled valves; Said transfusion catheter 4 is connected 7 through pipeline connector 6 with a level detection pipe; Level detection pipe 7 lower ends connect Mo Feishi dropper 8, are connected with step motor control flexible pipe 9 in said Mo Feishi dropper 8 lower ends; Said step motor control flexible pipe is provided with transfusion pipe clamp 10; Said float-controlled valve 2 comprises valve port 11, lower valve port 12 and Flat valve core 13, and said Flat valve core 13 is arranged in the valve pocket that forms between valve port 11 and the lower valve port 12.
Its operation principle is: make two drip switch be in closed condition before the transfusion, when inserting the perforator of first infusion bottle in the infusion bottle, under the effect of medicinal liquid pressure; Medicinal liquid flows into perforator; The Flat valve core of float-controlled valve intracavity is with the floating valve port place that is parked in of the inflow of medicinal liquid, and this moment, lower valve port was opened, and last valve port can not closed because of the stop of Flat valve core; Therefore medicinal liquid can flow in the transfusion catheter of float-controlled valve lower end; After first bottle liquid medicine was totally lost, air admission float valve pocket, Flat valve core descended with medicinal liquid and rest on lower valve port; Open the drip switch between second infusion bottle and the 3rd infusion bottle, begin second bottle of transfusion and since air admission the float-controlled valve intracavity under first infusion bottle; When atmospheric pressure equates with hydraulic pressure; The Flat valve core of the float-controlled valve intracavity under first infusion bottle still can rest on lower valve port, stops medicinal liquid to flow in first infusion bottle, when atmospheric pressure during less than hydraulic pressure; Hydraulic pressure forces the Flat valve core that rests on lower valve port to flow to and goes up valve port; And close and to close valve port, still stop medicinal liquid to flow in first infusion bottle, can carry out second bottle of transfusion smoothly thus; After second bottle of transfusion accomplished, open the drip switch between second infusion bottle and the 3rd infusion bottle, carry out the 3rd bottle of transfusion.
The level detection pipe of said Mo Feishi dropper upper end can realize dripping the detection of speed; Send detected result to single-chip microcomputer or other treatment facilities; The result who obtains processing passes to motor, pushes tube for transfusion through the action that motor is made, thereby obtains ideal speed.
Above-described only is the preferred implementation of this utility model, certainly, as the case may be, on the basis of this utility model, can increase the quantity of infusion bottle, also can reduce the quantity of infusion bottle.
Should be understood that for a person skilled in the art, under the prerequisite that does not break away from this utility model structure, can also make some distortion and improvement, these can not influence effect and practical applicability that this utility model is implemented.
