Abstract
The utility model relates to an in vitro negative pressure drainage instrument, which comprises a micro-catheter, a liquid bottle and a negative pressure ball, and is characterized in that a tee joint is arranged on a bottle cover of the liquid bottle; the micro-catheter is connected with one port of the tee joint on the bottle cover of the liquid bottle; the negative pressure ball is connected with the other port of the tee joint on the bottle cover of the liquid bottle; a non-return valve is arranged on the negative pressure ball; a side hole is arranged on the micro-catheter; and the liquid bottle is transparent, and the surface of the liquid bottle is provided with measuring scales. When the in vitro negative pressure drainage instrument is used, one end of the micro-catheter provided with the side hole is placed on the deep part of a surgical incision and the side hole of the micro-catheter is positioned inside a wound surface, so as to avoid air leakage after connection of negative pressure; the other end of the micro-catheter is led out from the lower end of the incision and is sewed and fixed on the skin of the surgical incision by a No. 1 thread; the tail end of the micro-catheter is connected with one port of the tee joint on the bottle cover of the liquid bottle, the negative pressure ball is extruded repeatedly, and air in the liquid bottle is emptied through the non-return valve, so that the negative pressure is formed in the bottle and exudate in the surgical incision can be led into the liquid bottle, thereby the exudate in the liquid bottle can be dumped through observing the measuring scales which are arranged on the surface of the liquid bottle.
Description
Technical field
This utility model relates to a kind of medical apparatus, specifically a kind of external depression drainage device.
Background technology
At present, be known in some conventional body surface minor operations after, depression drainage device drain commonly used, but depression drainage device commonly used, the one, volume is bigger; The 2nd, inside is provided with spring, and the 3rd, switch is provided with unreasonable.When daily use, one is to use inconvenience; The 2nd, spring often punctures bag; The 3rd, when falling the sepage inconvenience.
Summary of the invention
In order to overcome existing deficiency with rubber bar drainage technology.This utility model provides a kind of external depression drainage device.This external depression drainage device.Not only can be with the timely drain of courageous and upright sepage in the wound, and can prevent the infection of otch, 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: a kind of external depression drainage device, it comprises micro catheter, liquid bottles and negative pressure ball, it is characterized in that: the liquid bottles bottle cap is provided with threeway, a port of threeway joins on micro catheter and the liquid bottles bottle cap, negative pressure ball joins by another port of threeway on conduit and the liquid bottles bottle cap, negative pressure ball is provided with check valve, and micro catheter is provided with side opening, and liquid bottles is that transparent surface also is provided with metering scale.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, is fixed on the operative incision skin with a silk suture.A port of threeway joins on micro catheter end and the liquid bottles bottle cap, push negative pressure ball repeatedly, by the air in the check valve evacuation of liquid bottle, make and form negative pressure in the bottle, sepage in the operative incision is guided in the liquid bottles, can in time the sepage in the liquid bottles be outwelled by observing the metering scale that the liquid bottles surface is provided with.
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.
Accompanying drawing is this utility model structural representation.
Among the figure, 1. side opening, 2. micro catheter, 3. threeway, 4. conduit, 5. negative pressure ball, 6. check valve, 7. bottle cap, 8. liquid bottles, 9. metering scale.
The specific embodiment
In the drawings, a kind of external depression drainage device, it comprises micro catheter 2, liquid bottles 8 and negative pressure ball 5, it is characterized in that: liquid bottles 8 bottle caps 7 are provided with threeway 3, a port of threeway 3 joins on micro catheter 2 and liquid bottles 8 bottle caps 7, and negative pressure ball 5 joins by another port of threeway 3 on conduit 4 and liquid bottles 8 bottle caps 7, and negative pressure ball 5 is provided with check valve 6, micro catheter 2 is provided with side opening 1, and liquid bottles 8 is that transparent surface also is provided with metering scale 9.An end that during use micro catheter 2 is had side opening 1 is put in the deep of operative incision, makes micro catheter 2 side openings 1 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, is fixed on the operative incision skin with a silk suture.A port of threeway 2 joins on micro catheter 2 ends and liquid bottles 8 bottle caps 7, push negative pressure ball repeatedly, by the air in the check valve 6 evacuation of liquid bottles 8, make and form negative pressure in the bottle, sepage in the operative incision is guided in the liquid bottles 8, can in time the sepage in the liquid bottles be outwelled by observing the metering scale 9 that liquid bottles 8 surfaces are provided with.
