Abstract

A no-bubble infusion device mainly solves the problems that when the prior infusion device is used for transfusion, a plurality of small bubbles accompanied with liquid medicine flow into body of the patient from the filter, thereby causing less safety of infusion. The technical proposal of the infusion device is that: the utility model comprises a bottle thorn, a dropping bucket, a switch, a filter, a catheter and an intravenous needle, and is characterized in that: the filter is connected between the bottle thorn and the dropping bucket, the catheter below the dropping bucket is connected with the intravenous needle by a tubiform connecter, and the utility model has the advantages of convenient operation, no bubble in the process of infusion, safe and reliable infusion.

Description

Bubble-free infusion set

Technical field:

This utility model belongs to a kind of medical apparatus, particularly a kind of bubble-free infusion set.

Background technology:

The present used transfusion device of medical system, the technical standard that is National Quality ﹠ Technology Inspection Bureau's issue of enforcement on February 1st, 1999 is transformed, primary standard is that drainage screen is at the dropping funnel inner bottom part, owing to be inconvenient to operate during work, so manufacturer takes out drainage screen and makes the filter that can use as joint separately from the dropping funnel inner bottom part, use for connecting intravenous needle, yet, this filter is exactly the place of production of bubble, so patient generally believes that always having some minute bubbles when transfusion follows medicinal liquid to flow in the patient body together from filter, make patient cure chronic illness and add new disease again, this is an obvious deficiency of existing transfusion device.

The utility model content:

At the above-mentioned deficiency of existing transfusion device, the purpose of this utility model provides a kind of no bubble that meets the technical standard of State Quality Supervision Bureau's requirement, easy-operating transfusion device.

The purpose of bubble-free infusion set is achieved in that it comprises bottle pricking device, dropping funnel, switch, filter, catheter and intravenous needle.The catheter that it is characterized in that being connected between bottle pricking device and dropping funnel below filter, the dropping funnel connects intravenous needle by tubular configured joint.

The utility model has the advantages that: can reach easy to operate, not have the effect that bubble produces during transfusion, it is safe and reliable to infuse.

Description of drawings:

Fig. 1 is the structural representation of this utility model embodiment 1.

Fig. 2 is the structural representation that tubulose connects bucket.

Fig. 3 is the structural representation of this utility model embodiment 2.

Fig. 4 is the whole body structure sketch map of filter and dropping funnel.

The specific embodiment:

Embodiment one: see Fig. 1, shown in Figure 2, the bottle pricking device of prior art (1) lower end connects the filter (3) of prior art by catheter (2), filter (3) lower end connects the dropping funnel (4) of prior art by catheter (2), the switch (5) of the outer suit prior art of catheter (2) pipe that dropping funnel (4) lower end connects, in the top connection (8) of the lower end of catheter (2) connection tube straight coupling (6), intravenous needle (7) socket of the lower contact (9) of tubular configured joint (6) and prior art.

Operation principle: when the upper end of bottle pricking device (1) is pricked in the transfusion bottle, medicinal liquid flows to catheter (2) along bottle pricking device (1), flow to filter (3) again, at this moment from the medicinal liquid that filter (3) lining flows out, have a small amount of bubble to follow medicinal liquid to flow in the dropping funnel (4) of lower end.Because of dropping funnel (4) is watched a speed, so the medicinal liquid in the dropping funnel (4) only accounts for the about 1/3 many of dropping funnel, so also have about 2/3 big spaces, this space not only can be watched and drip speed, can be housed in the inside to the minute bubbles that flow out in the filter (3) again, only the intravenous needle (7) of medicinal liquid input lower end is flowed into human body, Here it is is installed in the top reason of dropping funnel (4) to filter (3), has so just realized easy to operate.Do not produce the purpose of bubble during transfusion.

Embodiment two: see Fig. 3, shown in Figure 4: its structure is that the filter (3) prior art and the dropping funnel (4) of prior art are made an integral body, filter is on top, dropping funnel is in the bottom, the upper end (10) of filter (3) connects bottle pricking device (1) by catheter (2), and the lower end (11) of dropping funnel (4) is by the upper end (8) of catheter (2) connection tube straight coupling (6).The lower end (9) of tubular configured joint (6) connects intravenous needle (7).Other and operation principle are the same.

Claims

1, a kind of bubble-free infusion set comprises bottle pricking device, dropping funnel, switch, filter, catheter and intravenous needle, and the catheter that it is characterized in that being connected between bottle pricking device and dropping funnel below filter, the dropping funnel connects intravenous needle by tubular configured joint.

2, bubble-free infusion set according to claim 1 is characterized in that: filter and dropping funnel are made an integral body, and filter is on top, and dropping funnel is in the bottom.
