CN2278483Y - Transfusion system capable of improving exhaust effect - Google Patents

Abstract

The utility model discloses a medical infusion device capable of improving exhaust effect. Because the drip opening of the drip tube is closely connected with the water outlet before the infusion of the device is started, the liquid can directly enter the lower infusion tube from the upper infusion tube. After the exhaust is finished, the upper end and the lower end of the dropping liquid pipe are slightly pulled, and the liquid level height and the air space meeting the requirements can be generated in the dropping liquid pipe. The device can not adhere to the bubble on the pipe wall when exhausting the operation, and not only convenient safety has also avoided the phenomenon of the extravagant liquid medicine that leads to because of exhausting unfavorable moreover.

Description

Can improve the transfusion device of exhaust effect

This utility model relates to a kind of medical Transfusion device, and particularly a kind of transfusion device that can improve exhaust effect is suitable for clinically using when giving patient infusion.

When utilizing transfusion device to give patient infusion, at first to carry out bleeding.This work will be finished minim pipette and tilts in short-term, the syringe needle open and close, and actuator multi-mode operation such as close.If when the air inlet pipe backwater takes place, also will will carry on the air inlet pipe, close an operation such as air inlet pipe, therefore, more common nurses carry out deflated phenomenon after having to owing to clinical manipulation is unfavorable a part of medicinal liquid bled off again.Like this, not only waste medicinal liquid, and, can be difficult to remove with many minute bubbles on the inwall of following tube for transfusion, and then cause a hidden trouble for the air admission human body.

Once proposed in the utility model patent (92211168.5) " transfusion device of handled easily ", still, the structure that is limited to this device is loaded down with trivial details, fails so far to be applied.

This utility model is to provide a kind of further improved, can obviously improve the transfusion device of exhaust effect.Use it, not only can reach the once success of bleeding, nor can on the inwall of tube for transfusion, adhere to bubble.

This utility model is achieved in that the minim pipette in the transfusion device makes with whippy flexible plastic, before the use, the water side of minim pipette is pushed into minim pipette inner connecting airtight with water inlet end and is in the same place, and when bleeding, liquid just can flow directly into down in the tube for transfusion without titration process like this.After treating the syringe needle water outlet, the two ends of minim pipette are drawn back gently, can be reached the job requirement that in minim pipette, leaves an amount of air.

This utility model structurally has tangible progress, and bleeding is convenient, safety, and therefore the generation that can stop secondary aerofluxus phenomenon fully, is particularly suitable for newly appointed nurse and uses.Simultaneously,, but determine, therefore, help the standardized designs of this index by what of minim pipette compression time institute's spacing because what of the gas of leaving a blank are not by the nurse in the minim pipette.

Below, will be described in further detail this utility model in conjunction with the accompanying drawings.

Fig. 1 is the sketch map of a kind of concrete structure of this utility model, the situation when representing to carry out aerofluxus after it is installed on the infusion bottle.

Fig. 2 is the sketch map that amplifies the minim pipette (6) of twice among Fig. 1.

Fig. 3 after aerofluxus finishes, draws back the minim pipette two ends sketch map when minim pipette enters normal operating conditions.

Fig. 4 is that it is identical with minim pipette function shown in Figure 3 according to the work sketch map of another minim pipette that the utility model proposes.

Minim pipette among Fig. 1, Fig. 2, Fig. 3, Fig. 4 is all the A end and is water inlet end, and the B end is the water side.

With reference to Fig. 1, except that minim pipette (6), the manufacturing of all the other air inlet pipe (1), transfusion needle (4), upper tubing (5), following tube for transfusion (7), adjusting device (3) and syringe needle (2) and matching requirements are with traditional mode.

For minim pipette (6), should select for use whippy medical soft plastics to make, its shape is roughly ovum circle (or inverted cone) shape structure wide at the top and narrow at the bottom.During as product export, its water side B (narrow end) is pushed into minim pipette inside, be with the water dropping openings (8) of water inlet end A (wide end) closely closing together, as shown in Figure 2.

The using method of this utility model: with reference to Fig. 1, transfusion needle (4) is thrust in the infusion bottle of hanging, at this moment liquid just flows directly into down in the tube for transfusion (7) through water dropping openings (8) by transfusion needle (4), upper tubing (5), when liquid arrives syringe needle (2), the two ends of minim pipette are drawn back gently, as shown in Figure 3, can form certain liquid level and air space automatically in the middle of the minim pipette.After treating the syringe needle water outlet again, can begin to patient injection.

Minim pipette shown in Figure 4 is except that the basic structure that possesses Fig. 1, Fig. 2, Fig. 3 minim pipette, also make a bottleneck structure that attenuates suddenly (9) in the middle, like this, water side B can pushed minim pipette when inner, improve the tightness degree that contacts of water side B and water dropping openings (8) effectively.

Claims (3)

1. the medical Transfusion device that can improve exhaust effect is compared with the traditional infusion device, it is characterized in that also comprising a new-type minim pipette (6); The water side B of said new-type minim pipette (6) is pushed into minim pipette inside, makes the tight closing of water side and water dropping openings (8) together.

2. device according to claim 1 is characterized in that, as the A of minim pipette, when entering normal operating conditions after the B two ends are drawn back, the minim pipette overall shape is long ovum (or inverted cone) shape structure wide at the top and narrow at the bottom; Its width ratio is as the criterion can be easily the water side B (narrow end) of minim pipette be pushed and pull out minim pipette.

3. device according to claim 1 and 2 is characterized in that being provided with at the middle part of minim pipette the bottleneck structure (9) that attenuates suddenly.
