CN201098454Y - Negative pressure fluid conducting device - Google Patents

Abstract

The utility model discloses a negative pressure liquid conducting device which is characterized in that the upper end of a hand pump marked with a measuring scale is connected with a check valve and a micro-catheter. The lateral surface of the end part of the micro-catheter is provided with a plurality of elliptical holes. The diameters of the lateral holes are smaller than the diameter of the catheter. The lower end of the hand pump is connected with a transfusion tube which is provided with a switch. The end, which is provided with lateral holes, of the tenuous catheter is put into the deep portion of a surgical incision when the negative liquid conducting device is used, so that the lateral holes of the tenuous catheter are positioned inside the wound surface lest air leak occurs after the liquid conducting device is connected with negative pressure. The other end of the tenuous catheter is led out from the lower end of the incision, and is seamed to be fixed on the skin of the surgical incision by number one plush. The check valve at the upper end of the hand pump of the negative pressure liquid conducting device is connected with end of the tenuous catheter. After the hand pump is squashed and the switch at the lower end of the hand pump is closed, negative pressure is formed, and the endosmotic liquid of the surgical incision is led out.

Description

Depression drainage device

Technical field

This utility model relates to a kind of medical apparatus, specifically a kind of depression drainage device.

Background technology

At present, after being known in some conventional body surface minor operations, rubber bar drain commonly used, but rubber bar matter is soft, approach, easily come off, easily caused inadequate drainage by the otch extruding, cause wound hematocele, hydrops, cause wound infection not healed, cause the courageous and upright sepage that drains easily to soak dressing, influence the isolation of antibacterial, and cause the traumatic psychological fear of patient, simultaneously, postoperative will repeatedly be changed incision dressing in 48 hours, had increased medical personnel's workload and patient's financial burden.

Summary of the invention

In order to overcome existing deficiency with rubber bar drainage technology.This utility model provides a kind of depression drainage device.This depression drainage device not only can be with the timely drain of courageous and upright sepage in the wound, and can measure and prevent the infection of otch, and medical personnel can in time take corresponding measure according to flow, and otch is healed early.

The technical scheme that its technical problem that solves this utility model adopts is: be connected to check valve and micro-conduit in the hand pump upper end that indicates metering scale, trace end of conduit side is provided with several slotted eyes, this side opening diameter is less than conduit diameter, the hand pump lower end is connected to tube for transfusion, tube for transfusion is provided with switch, an end that during use micro catheter is had side opening is put in the deep of operative incision, makes the micro catheter side opening be positioned at wound surface, in order to avoid leak gas after connecting negative pressure.The other end is drawn from the otch lower end, with a velvet sutured on operative incision skin.The check valve of simple and easy metering depression drainage device hand pump upper end is connected with micro catheter is terminal, flattens hand pump, close end switch under the hand pump, form negative pressure, draw sepage in the operative incision.

The beneficial effects of the utility model are: medical personnel can in time adopt corresponding measure according to drainage flow, and otch is healed early.

Description of drawings

Below in conjunction with accompanying drawing this utility model is further specified.
