Abstract

This utility model discloses a kind of transfusion device, solves in infusion process and easily occurs to enter the problems such as air in blood backflow and blood.It is primarily of contact pin, infusion tube, kettle, a closer and injection needle composition, and it is characterized in that: in a kettle, have a fluid stopping ball float, there is a fluid stopping groove below simultaneously in a kettle.Described fluid stopping ball float is hollow ball, and its diameter is the half of dripping kettle diameter.Described fluid stopping groove is surrounded by arc surface, and its inscribe diameter of a circle is identical with fluid stopping floating ball diameter.This utility model is when medicinal liquid has soon flowed, drip kettle inner liquid medicine amount to reduce, fluid stopping ball float declines, thus medicine liquid outlet is blocked, realize automatically stoping medicinal liquid to continue dirty, thus prevent blood backflow and blood from entering the accident generations such as air, this utility model structure is simple, easy to use, the design of fluid stopping ball float and fluid stopping groove, may be used in any model transfusion device.

Description

There is the transfusion device of automatic flow-stop function
Technical field
This utility model relates to medical supplies, especially a kind of transfusion device with automatic flow-stop function.
Background technology
Transfusion is a kind of common administering mode, by infusion tube and injection needle by the injecting liquid drug in transfusion bag in human body, at present when infusing, when medicinal liquid has soon flowed, if do not pull up injection needle in time, air may enter blood by injection needle, work the mischief, or blood can be back in infusion tube by injection needle, can flexible pipe be blocked when blood solidifies in injection hose, when if desired again changing injecting liquid drug, can only transducer set syringe again, again have an acupuncture treatment, bring misery to patient.
Summary of the invention
In order to solve the problems of the technologies described above, this utility model provides a kind of transfusion device, when medicinal liquid has soon flowed, can automatically stop medicinal liquid to continue dirty, is full of medicinal liquid in a section of guarantee infusion tube, prevents blood backflow and blood from entering the accidents such as air and occurs.
The technical scheme in the invention for solving the technical problem is:
Have a transfusion device for blocking function, primarily of contact pin, infusion tube, drip kettle, closer and injection needle composition, it is characterized in that: in a kettle, have a fluid stopping ball float, there is a fluid stopping groove below simultaneously in a kettle.
Preferably, described fluid stopping groove is surrounded by arc surface, and its inscribe diameter of a circle is identical with fluid stopping floating ball diameter.
Preferably, described fluid stopping ball float is hollow ball, and its diameter is the half of dripping kettle diameter.
Preferably, described fluid stopping ball float is vinyon material, and its global density is less than the density of water.
The beneficial effects of the utility model are,
This utility model, when medicinal liquid has soon flowed, drips kettle inner liquid medicine amount and reduces, the decline of fluid stopping ball float, thus is blocked by medicine liquid outlet, realizes automatically stoping medicinal liquid to continue dirty, thus prevents blood backflow and blood from entering the accident generations such as air.This utility model structure is simple, and easy to use, the design of fluid stopping ball float and fluid stopping groove, may be used in the transfusion device of any model.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described.
Fig. 1 is this utility model overall structure schematic diagram.
Fig. 2 is that this utility model drips part-structure schematic diagram in kettle.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is further described.
As shown in Figure 1, this utility model forms primarily of contact pin 1, infusion tube 2, a kettle 3, closer 4, injection needle 5.The effect of described closer is can regulating flow velocity as required.
As shown in Figure 2, have fluid stopping ball float 31 in kettle 3 inside, fluid stopping groove 32 is positioned at the below of dripping kettle inside.
The diameter of described fluid stopping ball float is drip kettle diameter 3/1 to four/3rds, and preferably, the diameter of fluid stopping ball float is for dripping kettle diameter 1/2nd; Preferably, the inscribed circle diameter of described fluid stopping groove is identical with fluid stopping floating ball diameter; The height of described fluid stopping groove is 1/1 to two/4th of its inscribed circle diameter, and preferably, the height of fluid stopping groove is 1/3rd of its inscribed circle diameter.Be equipped with medicine liquid outlet in the interposition of the bottom land of fluid stopping groove, this outlet is communicated with infusion tube.
In actual use, described fluid stopping ball float also can be medicine ball, makes by other various materials, as long as the density of its entirety is less than the density of water.The height of described fluid stopping groove is unsuitable too high, otherwise when again infusing, drip in kettle and enter medicinal liquid, fluid stopping ball float cannot float.
Contact pin in use, inserts in the outlet cork of transfusion bag by this utility model, and medicinal liquid enters to drip kettle by transfusion plastic flow, and when having medicinal liquid in a kettle, fluid stopping ball float can swim on medicinal liquid, does not hinder medicine stream to flow; When medicinal liquid is about to be finished, drip kettle inner liquid medicine and decline, fluid stopping ball float declines thereupon, and then contact with fluid stopping groove, because fluid stopping ball float is identical with fluid stopping groove inscribed circle diameter, the medicine liquid outlet at fluid stopping bottom land place after contact, fully can be sealed, thus prevent air from entering, stop medicinal liquid to continue dirty.
Those skilled in the art can carry out various remodeling and change to this utility model.Therefore, this utility model cover fall into appending claims and equivalent thereof scope in various remodeling and change.
