Abstract
The utility model relates to a double-adjusting infusion device, belonging to the technical field of medical appliances. The utility model is mainly composed of an infusion bottle (1), a liquid inlet needle (2), an air inlet conduit (3), infusion pipes (4), (12), and (13), a Murphy's dropper (6), a lower adjusting switch (7), an emulsion connecting pipe (9), a filter (10), a plastic thin pipe (11), and a scalp needle. The utility model is characterized in that an upper adjusting switch (5) is added at the upper end of the Murphy's dropper (6). The utility model has the advantage of simple operation, reduces the unnecessary pain for patients in the process of infusion, and ensures the safety of users.
Description
This utility model is a kind of two transfusion device of regulating, and it belongs to medical instruments field.
Present employed disposable transfusion device, blood back is not obvious, makes the operator can't judge whether scalp acupuncture has inserted in the patient vessel; In clinical use, the medical personnel often takes some measures according to clinical experience, for example: lofty tone low level method; Promptly open big current-intercepting switch, infusion bottle is lowerd, reduce the liquid level of transfusion device, so that blood back in the scalp acupuncture carries out normal infusion then.But for the Hypovolemia patient,, take any measure all of no avail, thereby bring a lot of troubles, increased a lot of unnecessary miseries to patient to the operator because vein forces down.
The purpose of this utility model is to improve the structure of existing transfusion device, overcomes above-mentioned shortcoming, makes once success of puncture.
In order to achieve the above object, this utility model now is illustrated by the following technical solutions in conjunction with the accompanying drawings:
Fig. 1 is two structural representations of regulating transfusion device.
Fig. 2 is the feed liquor needle construction sketch map that uses at present.
Fig. 3 is a side opening feed liquor needle construction sketch map.
As shown in Figure 1, existing disposable transfusion device is made up of infusion bottle (1), feed liquor pin (2), air induction conduit (3) woven hose (4), (12) and (13), Murphy's burette (6), lower by-pass cock (7), latex adapter (9), filter (10), plastic straw (11) and scalp acupuncture (8). The utility model is that the upper end of Murphy's burette in said structure (6) increases an adjusted switch (5), and this switch can be identical with lower by-pass cock (7) structure, and material all adopts plastics to make.
At first close lower by-pass cock during use, the extruding Murphy tube is closed rapidly the adjusted switch then, makes in this section pipe to be in negative pressure; At this moment, the operator can puncture (not wanting the excessive compression Murphy's burette, in order to avoid negative pressure is excessive), after scalp acupuncture enters skin, open lower by-pass cock, the syringe needle intravasation, blood back is just obviously arranged, open immediately the adjusted switch, the liquid in the infusion bottle just enters patient's intravenous.
For the patient of Hypervolemia, can use the adjusted switch, use disposable transfusion device routinely.
The present matching used feed liquor pin of disposable transfusion device, its structure and transfusion needle identical (as shown in Figure 2), when inserting the rubber stopper of infusion bottle, often a lot of rubber grains under the cutting enter in the liquid that will import, cause great harm to patient.Therefore, this utility model adopts side opening feed liquor pin (2) (as shown in Figure 3), and it is conical that the feed liquor pin is, and has inlet opening (14) in the side and can improve the degree of purification of transfusion greatly.
This utility model is in clinical use, and is simple to operate, reduced the unnecessary painful and harm of patient in infusion process, is the desirable apparatus of venous transfusion.
Claims (3)
1, a kind of two transfusion device of regulating, take over (9), filter (10) plastic straw (11) and scalp acupuncture (8) by infusion bottle (1), feed liquor pin (2), air induction conduit (3), tube for transfusion (4), (12) and (13), Murphy's burette (6), following by-pass cock (7), latex and form, it is characterized in that: the upper end at Murphy's burette (6) increases an adjusted switch (5).
2, two transfusion device of regulating according to claim 1, it is characterized in that: feed liquor pin (2) is conical, and its side has inlet opening (14).
3, two transfusion device of regulating according to claim 1, it is characterized in that: adjusted switch (5) and following by-pass cock (7) are all made of plastic.
