Technical field
The present invention relates to a kind of combinations of puncture drainage to wrap, more specifically, more particularly to a kind of suitable for paracentesis pericardii, chest
The puncture drainage combination packet that chamber is punctured and drained.
Background technique
The hydrops to human body privileged site is clinically needed to drain, such as paracentesis pericardii, thoracentesis, after puncture again
Insertion drainage sheath, and drainage bag is connected in the end of drainage sheath, hydrops in patient body can be drained to drainage bag in this way
It is interior.But currently without the device dedicated for paracentesis pericardii, thoracentesis and drainage, but use traditional central venous catheter
Packet is to replace；Since central venous catheter is not necessarily to draw body fluid, therefore not setting drainage device in central venous catheter packet,
It is connected after deep venouspuncture insertion human body therein with infusion device, to carry out Deep venou injection.
Therefore, after carrying out paracentesis pericardii or thoracentesis using central venous catheter packet, usually using anti-reflux drainage bag
As drainage bag, drainage bag is connected to deep venouspuncture by short tube section, is then wound the both ends of short tube section with adhesive tape solid
It is fixed, so that body fluid is drawn.But due to being connected using adhesive tape, the connector of the connector and drainage bag that lead to deep venouspuncture connects
It connects insecure, when patient turns over or motion amplitude is larger, will lead to deep venouspuncture and drainage bag junction and disconnect, will lead to
Deep venou pipe is communicated with the outside world to flow out with hydrops, seriously affects normal therapeutic and the safety of patient, while the liquid drained is dirty
Contaminate sheet, bedding etc..
