10) negative pressure ball：Negative pressure ball is by negative pressure sphere, lower end liquid outlet, upper end air inlet, unidirectional valve union and liquid stopping clamp groupInto being made of silastic material.As shown in Figure 1.
11) drainage bag：Drainage bag is made of bag body, connecting tube, hanging ring and leakage fluid dram, wherein leakage fluid dram can as needed intoRow selection, can be equipped with can also not have, and be made of PVC material,, can the row of opening when needing drain if setting leakage fluid dramLiquid mouth switchs direct drain, is not required to remove drainage bag and topple over, easy to operate；If being not provided with leakage fluid dram, drainage bag can only be removedTopple over hydrops, then reinstall drainage bag, it is cumbersome；Exhaust outlet, which may be provided at, also may be provided at negative pressure ball on drainage bagOn, but be arranged on drainage bag more convenient for operation.The two is not related to the variation in terms of designing with technology properties.As Fig. 6,7th, shown in 8,9,10.
12) pecker：Pecker is made of medical 304 stainless steel material, and main function is skin, tissue perforation, determinesDrainage pathway helps drainage tube to be inserted into the needed by human body position to be drained.Pecker front end is put the first edge on a knife or a pair of scissors, and has sharp needle tip, and middle part is curvedFolding processing, there is a conduit connecting pin in tail portion, to connect drainage tube.As shown in Fig. 2,3,4,5.
This drainage catheter is set with, and can effectively be prevented and be reduced the generation of abscess, inflammation, wound can be helped to be cured wellIt closes, it is significant to prevention infected wound, the generation of complication is reduced, is palliated the agonizing sufferings for patient, helps its smooth recovery.ForSurgical operation drains, by the purulence gathered between tissue or in body cavity, clot or other liquid guide flows to external after wound closing.It can prevent and reduce abscess, the generation of inflammation, prevent infected wound, reduce the generation of complication.Being set with by drainage catheter willBlood, body fluid etc. excrete between tissue or in body cavity, prevent it in body cavity, tissue between or surgical field of view in assemble,In order to avoid tissue damage, secondary infection etc.；Fester and slough can also be discharged simultaneously, prevents infection from spreading；In addition to this, moreover it is possible toSurgical field of view dead space is promoted to reduce or be closed, ensures that wound well heals, promotes sufferer early recovery.
Relative to previous drainage catheter for surgical operation, have in practicability, safety, operability, comfortMany advantages.Whether in pipe complete product, it will become most of medical staff within the next few days for medical staff or patient's all pro-gazesThe common selection with patient.Drainage catheter for surgical operation, which is sleeved in economic well-being of workers and staff, higher value.Drainage catheter is set with cityField prospect is very wide, and demand and development space are huge, economic benefits.
