Abstract
The utility model provides an improved transfusion device. The utility model has a puncture head, wherein, an air inlet pipe is communicated to the puncture head. A transfusion pipe which is communicated with a main pipe is arranged on the puncture head. A Murphy's dropper and a dropping speed switch are arranged on the main pipe. The end of the main pipe is provided with a puncture needle head. A blocking device of a pipe cavity for the main pipe is arranged inside the Murphy's pipe. The transfusion device has the advantages of easy use and safety. The blocking device of the pipe cavity for the main pipe is composed of a floating ball and a plunger piston which is arranged on the floating ball and is used for blocking the pipe cavity for the main pipe. When air is exhausted, the Murphy's dropper only needs pressing in order to cause the floating ball to float. The air exhaustion can not lead the condition that air enters the Murphy's dropper. When liquid medicine transfused completely or an infusion bottle is changed, the plunger piston on the floating ball can block the pipe cavity for the main pipe. The phenomenon that the air enters the Murphy's dropper to cause the danger because of time delay and careless nursing can be avoided.
Description
Technical field
This utility model provides a kind of transfusion device, belongs to a kind of medical apparatus.
Background technology
Transfusion is the administering mode commonly used of treatment disease.But, bring a lot of inconvenience to medical personnel, even patient is caused danger because existing structural deficiency of transfusion device and patient and families of patients are understood the transfusion lack of knowledge.Show that mainly existing transfusion device is before transfusion, when discharging the gas in the transfusion device, need when puncturing head is thrust the infusion bottle plug, the Mo Feishi pipe is stood upside down, push the Mo Feishi pipe then, make and enter a certain amount of medicinal liquid in the Mo Feishi pipe, at last Mo Feishi is managed upright.So not only complicated operation also easily causes gas to enter the following transfusion device of Mo Feishi pipe.Transfusion should be extracted piercing needle or change infusion bottle after finishing immediately.Careless as unmanned nurse or nurse, can cause gas to enter.In infusion process, also can enter, the gas embolism phenomenon occur owing to a variety of causes causes the gas more than the Mo Feishi intraluminal fluid face.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of improved transfusion device, to improve convenience and the safety of using.
This utility model is to realize like this, a kind of improved transfusion device, it has puncturing head, be communicated with air inlet pipe on the puncturing head, also have tube for transfusion to be communicated with on the puncturing head with the person in charge, the Mo Feishi pipe is arranged on the person in charge and drip fast switch, being responsible for end has piercing needle, and the tube chamber of person in charge blanking plug is arranged in described Mo Feishi pipe.
Adopt a kind of improved transfusion device of said structure, easy to use, safe.Being responsible for the tube chamber blanking plug can constitute by being used to stop up the plunger of being responsible for tube chamber on ball float and the ball float.During aerofluxus, only need extruding Mo Feishi pipe, ball float is floated get final product, can not enter because of aerofluxus causes gas.Plunger when medicinal liquid is totally lost or is changed infusion bottle on the ball float can be responsible for tube chamber and stop up, and has avoided causing gas to enter, bring dangerous phenomenon accidentally because of delay time at stop or nurse.
Description of drawings
Fig. 1 is the sketch map of a kind of example structure of this utility model.Fig. 2 is its A-A profile.Fig. 3 is the sketch map of its another kind of Mo Feishi pipe inner structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates structure of the present utility model and operation principle.
As shown in drawings, a kind of improved transfusion device of this utility model, it has puncturing head (2), be communicated with air inlet pipe (1) on the puncturing head, also have tube for transfusion (4) to be communicated with on the puncturing head with the person in charge (5), Mo Feishi pipe (6) is arranged on the person in charge and drip fast switch (8), being responsible for end has piercing needle (9), and the tube chamber blanking plug (7) of person in charge is arranged in described Mo Feishi pipe (6).
Ball float (7-2) is arranged on described person in charge's tube chamber blanking plug (7), be useful on the ball float and stop up the plunger (7-3) of being responsible for tube chamber.
Described puncturing head has two or more, and switch (3) is arranged on the tube for transfusion (4).Like this, when infusing, can close or open tube for transfusion, change infusion bottle or use separately by switch to patient.
Zhi Yi (7-1) is arranged on described ball float (7-2).Ball float is floated controllably vertically.
Transfusion device as shown in Figure 1 in use, when the medicinal liquid in the Mo Feishi pipe reached a certain amount of, the ball float come-up person in charge was open state.When the medicinal liquid in the infusion bottle dripped off, the liquid level in the Mo Feishi pipe descended, and plunger descends with ball float, stopped up person in charge's tube chamber gas and can not enter in the following transfusion device of Mo Feishi pipe.To be responsible for tube chamber in order stopping up more reliably, aciculiform bar (7-4) can be installed under plunger.
The operation principle of transfusion device shown in Figure 3 is identical with above-mentioned principle.
Obviously, be responsible for the tube chamber blanking plug other various ways can also be arranged.
Claims (4)
1, a kind of improved transfusion device, it has puncturing head (2), be communicated with air inlet pipe (1) on the puncturing head, also have tube for transfusion (4) to be communicated with on the puncturing head with the person in charge (5), Mo Feishi pipe (6) is arranged on the person in charge and drip fast switch (8), being responsible for end has piercing needle (9), it is characterized in that, the tube chamber blanking plug (7) of person in charge is arranged in described Mo Feishi pipe (6).
2, a kind of improved transfusion device as claimed in claim 1 is characterized in that, ball float (7-2) is arranged on described person in charge's tube chamber blanking plug (7), is useful on the ball float to stop up the plunger (7-3) of being responsible for tube chamber.
3, a kind of improved transfusion device as claimed in claim 1 or 2 is characterized in that described puncturing head has two or more, and switch (3) is arranged on the tube for transfusion (4).
4, a kind of improved transfusion device as claimed in claim 2 is characterized in that, Zhi Yi (7-1) is arranged on described ball float (7-2).
