Abstract
The utility model is an air bubble-proof transfusion device, which is a vein transfusion device. The utility model is characterized in that a bubble-proof pipe is positioned inside of the below of a burette; first, make the burette reverse hung, and the drug liquid discharges the air from below to upper until the liquid flows into a below guide pipe. And then make the burette positively hung; because the air and the liquid are not mixed in the burette, air bubble will not be in the guide pipe. The device will guarantee the transfusion safe.
Description
This utility model relates to the category of medical apparatus and instruments, particularly bubble-proof transfusion device.
When existing transfusion device medicinal liquid entered dropping funnel, liquid was discharged the formation gas-liquid mixed downwards with the gas in the dropping funnel and is entered downcomer, produces bubble, and the bubble in the conduit must be got rid of fully and could be infused, otherwise, may produce serious malpractice.
For addressing these problems, there is a kind of transfusion device in dropping funnel, outlet to be stopped up with buoy, buoy floats when liquid reaches a certain amount of, and medicinal liquid flows into downcomer can prevent to produce bubble.But its complex structure, reliability are subjected to many factor affecting.
The purpose of this utility model is to be to provide a kind of improved bubble-proof transfusion device, and the simple in structure of it can prevent that again bubble from entering conduit.
The purpose of this utility model is achieved in that the downcomer Shen of existing transfusion device goes in the dropping funnel as anti-foam pipe.Dropping funnel reversal of the natural order of things during operation, medicinal liquid enters dropping funnel from bottom to top, and air is upwards discharged, medicinal liquid enters downcomer after being raised to anti-foam tube inlet again, and remaining gas is enclosed in the dropping funnel, and dropping funnel restored and just hung this moment, remaining gas rises, and liquid infra, air just can't enter downcomer.Enough observe the drop of dropper for the space that remaining gas is formed, anti-foam pipe must be longer than dropper.
The interior certain-length of dropping funnel is gone into as anti-foam pipe in the downcomer Shen that this utility model only needs to have transfusion device now, and structure and technology are all simple especially to be implemented easily.Owing to guarantee in downcomer, can not produce bubble, guarantee the safety of transfusion device, operator also reduce the trouble of aerofluxus bubble.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 and Fig. 2 are the profiles according to the bubble-proof transfusion device of this novel proposition.
Describe details and working condition in detail below in conjunction with Fig. 1 and Fig. 2 according to the concrete structure that the utility model proposes.
Bubble-proof transfusion device comprises a dropping funnel main body (1), and main intravital upper end is dropper (2), and the lower end is that anti-foam pipe (3) communicates with downcomer (4).
To scheme is example, dropping funnel reversal of the natural order of things (see figure 2) during operation, medicinal liquid was in dropper (2) enters dropping funnel (1) after bottle plug puncture unit (not drawing among the figure) was connected medicinal liquid, medicinal liquid (5) rises and enters downcomer (4) and transfusion needle (not drawing among the figure) through anti-foam pipe (3), just hanging (see figure 1) dropping funnel in remaining gas rising with dropping funnel this moment, medicinal liquid (5) infra, and gas can't enter downcomer (4), anti-foam pipe (3) is long, and then residual gas is many, and is short then few.For ease of the formation and the observation of drop, dropper (2) is following must certain space, so anti-foam pipe (3) must be longer than dropper (2).
Claims (2)
1, medical Transfusion device, particularly bubble-proof transfusion device have downcomer (4) and dropping funnel (1), it is characterized in that there is an anti-foam pipe (3) lower end in the dropping funnel (1), and it communicates with downcomer (4).
2, bubble-proof transfusion device according to claim 1 is characterized in that anti-foam pipe (3) must be longer than dropper (2).
