Abstract
The utility model discloses a transfusion device which comprises a puncture device, a transfusion tube, a semi floating automatic control dropping bucket and a transfusion needle head, wherein the puncture device is a single channel puncture device; the one third position of the bottom part of the puncture device is provided with a side hole; a semi floating automatic control valve is arranged in the dropping bucket; one side of the transfusion needle head is provided with a side hole. The utility model can automatically terminates transfusion process, causes physic liquor in a transfusion bottle is completely injected, effectively improves the phenomenon that the transfusion needle head is blocked by a blood vessel wall, and has the advantages of simple structure, convenient use, low cost, etc.
Description
Technical field
This utility model belongs to the clinical apparatus of using of medical treatment, particularly relates to a kind of transfusion device that can effectively prevent the air admission blood vessel, improve transfusion device perforator and infusion needle.
Background technology
In clinical practice, the Dispoable medical transfusion device monitors near the oneself that at the end need depend on continuous tour of medical personnel or patient in infusion process, if in the situation such as meet that medical personnel are absent from the scene or patient and entourage be sleeping, thereby will enter air in blood samples of patients refluence Transfusion needle pipe or the transfusion device and enter the patient vessel because of handling untimely making, the danger of air embolism takes place easily; The perforator of used transfusion device inserts in the infusion bottle, liquid when liquid in the infusion bottle also has perforator length high in the bottle just can not be exported, syringe needle must be transferred to some or finish transfusion, especially concerning having only 100 milliliters infusion bottle, the remainder proportion is bigger, influence transfusion effect; Infusion needle has only an infusion hole in clinical practice, situation about being stopped up by blood vessel wall is often arranged, need the nurse again the position of syringe needle to be adjusted, easily blood vessel wall is penetrated, make medical personnel occur a large amount of fruitless labours at work, caused psychological burden for again simultaneously patient or entourage.
Summary of the invention
This utility model is imported blood vessel as much as possible, is improved the transfusion device that infusion needle is stopped up by blood vessel wall for solving the technical problem that exists in the known technology and provide a kind of and can effectively prevent the air admission blood vessel, guarantee the infusion bottle herb liquid.
The technical scheme that this utility model is taked for the technical problem that exists in the solution prior art is: a kind of transfusion device comprises perforator, tube for transfusion, half floating automatic control dropping funnel and infusion needle.Perforator is the single channel perforator, and there is a side opening at 1/3 place, perforator bottom, and half floating internally piloted valve is arranged in the dropping funnel, is the olive shape plastic blister, and there is aperture on the surface, interior dress absorbent cotton, and a side of infusion needle has side opening.The side opening of perforator and the side opening of infusion needle are the trapezoidal hole of outer narrow inner width.
Advantage and the good effect that the utlity model has are: when medicinal liquid dripped off, transfusion device can stop infusion process automatically, can prevent effectively that air admission blood vessel or blood from flowing backwards in a large number; The infusion bottle herb liquid is transfused to as far as possible; Effectively improve infusion needle and stopped up by blood vessel wall, simple in structure, easy to use, cost is low etc.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure, 1 is perforator, and 2 is the perforator side opening, and 3 is tube for transfusion, and 4 is olive shape plastic blister internally piloted valve, and 5 is absorbent cotton, and 6 is aperture, and 7 is dropping funnel, and 8 is the infusion needle side opening, and 9 is infusion needle.
In the process of transfusion, when medicinal liquid when also having perforator (1) length high, medicinal liquid can not be flowed out in vertical hole, at this moment medicinal liquid can flow out from the side opening of opening at perforator (1) 1/3 (2), guarantee liquid feed in the bottle many be transfused to blood vessel, basic noresidue.
After the outlet of infusion needle (9) top was blocked, medicinal liquid can continue to flow out from side opening (8), does not need medical personnel to readjust needle position.
The side opening (2) of perforator (1) and the side opening (8) of infusion needle (9) are the trapezoidal hole of the narrow inner width in place, can effectively avoid in the process of puncture, the rubber grain on the bottle stopper being brought into perforator (1) stops up side opening (2) and the process of having an acupuncture treatment in to the damage of skin.
When transfusion finishes, when at the bottom of the medicinal liquid liquid level outside dropping funnel (7) 1/3 time, olive shape plastic blister (4) will move down, arrive the following exit of dropping funnel (4), owing in the plastic blister (4) absorbent cotton (5) that contains medicinal liquid is arranged, under the effect of gravity, will descend the outlet sealing, thus control transfusion automatically.
Claims (3)
1, a kind of transfusion device, comprise perforator (1), tube for transfusion (3), half floating automatic control dropping funnel (7) and infusion needle (9), it is characterized in that perforator (1) is the single channel perforator, there is a side opening (2) at 1/3 place, perforator (1) bottom, one olive shape, half floating internally piloted valve (4) is arranged in the dropping funnel (7), and a side of infusion needle (9) has side opening (8).
2, a kind of transfusion device according to claim 1 is characterized in that half floating internally piloted valve in the dropping funnel (7) is olive shape plastic blister (4), and there is aperture (6) on the surface, interior dress absorbent cotton (5).
3, a kind of transfusion device according to claim 1 is characterized in that the side opening (2) of perforator (1) and the side opening (8) of infusion needle (9) are the trapezoidal hole of narrow inner width outward.
