Abstract
Negative pressure puncture needle of the utility model is characterized by comprising a puncture needle, a transparent tube, a rubber ball, a syringe adapter connected in sequence. The puncture needle is connected with the transparent tube via an adaptor at a needle end, a switch being mounted between the syringe adapter and the rubber ball. Beneficial effects of the utility model lie in that when the needle enters the puncture chamber, a needle insertion in acupuncture is no longer used to avoid damage of visceral organs or the needle crosses the puncture object, which causes puncture failure, in particular acupuncture for encysted and multiple pyema which are hard to position and that with visceral organs behind the pyema, the utility model has higher success ratio; saves time; is safe and reliable; and avoids damage of visceral organs.
Description
(1) technical field
The invention belongs to medical needle, particularly a kind of negative-pressure puncture needle.
(2) background technology
In clinical piercing process, it is very loaded down with trivial details constantly to try to take out operation behind the inserting needle, particularly to many rooms of encapsulated effusion property hydrothorax, common puncture needle is difficult to successfully, try on to inhale and lose time, special puncture is easily injured internal organs, such as paracentesis pericardii, lacuna is little between pericardium and heart, easily injures heart.
(3) summary of the invention
The present invention is in order to remedy the deficiencies in the prior art, a kind of success rate height is provided, saves time, safe and reliable negative-pressure puncture needle.
The present invention is achieved through the following technical solutions:
Negative-pressure puncture needle of the present invention, its special character is: comprise piercing needle, transparent hose, rubber bulb, syringe adapter that connection successively communicates, piercing needle is connected with transparent hose by the backshank joint, between syringe adapter and the rubber bulb switch is installed.
The invention has the beneficial effects as follows, entering the people chamber of puncturing can find immediately, not the reuse inserting needle in case injure internal organs or pass the puncture target make puncture failure, particularly parcel property, many rooms property hydrops are difficult to have after localized hydrops and the hydrops puncture of internal organs, the success rate height, save time, safe and reliable, reduce visceral organ injury.
(4) description of drawings
Accompanying drawing is a structural representation of the present invention.
Among the figure, 1 piercing needle, 2 backshank joints, 3 transparent hoses, 4 rubber bulbs, 5 switches, 6 syringe adapters.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.
Negative-pressure puncture needle of the present invention comprises piercing needle 1, transparent hose 3, rubber bulb 4, syringe adapter 6 that connection successively communicates, and piercing needle is connected with transparent hose by backshank joint 2, and switch 5 is installed between syringe adapter and the rubber bulb.Rubber bulb is preferably 3 milliliters rubber bulb.
The preparation of negative-pressure puncture needle: with common piercing needle 1, the rear connects transparent hose 3, rubber bulb 4, switch 5, syringe adapter 6, and negative-pressure puncture needle is promptly made, and it is standby to put into the puncture bag.
The use of negative-pressure puncture needle: prepare before patient's art, position, with common pin, close the switch 5 of backshank during puncture, rubber bulb 4 is extruded into negative pressure, without clamp, piercing needle 1 enters and unclamps rubber bulb after subcutaneous, continues inserting needle, because of rubber bulb is negative pressure, after puncture puts in place, there is hydrops to pass transparent hose 3 immediately, illustrates and puncture successfully.If inserting needle does not have hydrops and passes transparent hose or lunge blood vessel and have blood to enter transparent hose or estimate that the puncture direction is not right, but the withdraw of the needle is to subcutaneous change direction inserting needle again, up to puncturing successfully.Backshank connects syringe by syringe adapter 6, opens switch 5, can take out hydrops, pneumatosis or injection.First needle tubing can be closed switch after taking out and expiring, and the emptying syringe is taken out second needle tubing again, extracts repeatedly.Need not reduce by operator as common puncture needle assistant clamp backshank, single with regard to complete operation, reduce and infect probability.
Negative-pressure puncture needle can repeatedly use, but the split sterilization is identical with common pin sterilization.
Claims (1)
1. negative-pressure puncture needle, it is characterized in that: comprise piercing needle (1), transparent hose (3), rubber bulb (4), syringe adapter (6) that connection successively communicates, piercing needle is connected with transparent hose by backshank joint (2), and switch (5) is installed between syringe adapter and the rubber bulb.
