Abstract
The utility model discloses an abdominal drainage tube, which comprises inner core tubes and an outer casing. The number of the inner core tubes is two. The inner diameter of the inner core tube is 2.5mm and the outer diameter of the inner core tube is 3.5mm. The utility model has the advantages that the probability of the blockage of the drainage tube is reduced, the drainage duration and the drainage effect are improved, the opportunity of infection caused by accumulated liquid and the opportunity of infection caused by the replacement of the inner core tubes are reduced, and the successful restoration of the patient is facilitated.
Description
Technical field
This utility model belongs to the medical auxiliary apparatus field, more specifically, and the novel peritoneal cavity drainage tube that uses when relating to a kind of hepatocarcinoma surgical operation.
Background technology
Behind the hepatocarcinoma surgical operation, peritoneal cavity drainage tube commonly used or ditube drainage.Abdominal cavity dual-casing drain, inner core tube are silica gel tube (internal diameter 3mm, external diameter 4mm), and trocar sheath is latex tubing (internal diameter 9mm, external diameter 10.5mm).Part in abdomen all has small side hole.Wherein trocar sheath connects saline bottle, can inwardly wash by water.Inner core tube connects negative pressure and outwards attracts, and can attract the normal saline and the Intraabdominal hydrops that pour.Yet inner core tube connects negative pressure, easily nethike embrane, tissue or blood clot is attracted, and causes the side opening of inner core tube to stop up.If the two sleeve pipes of postoperative have stopped up too early, the effect of intraperitoneal drainage promptly disappears, and then can cause infection for hydrops, is unfavorable for that patient recovers.
The utility model content
The technical problems to be solved in the utility model provides a kind of probability that drainage tube stops up that reduces, and improves the peritoneal cavity drainage tube of drainage time and effect.
For solving the problems of the technologies described above, this utility model provides a kind of peritoneal cavity drainage tube, comprise inner core tube and trocar sheath, head end is respectively equipped with circular port, and the inner core tube diameter is characterized in that less than trocar sheath: described inner core tube is two, described trocar sheath has two be able to hold the aperture that inner core tube is passed through, inner core tube pierces into trocar sheath by aperture respectively, and the inner core tube size is internal diameter 2.5mm, external diameter 3.5mm.
This utility model is subsidized by national major scientific and technological project (2008ZX10002-025), and existing ditube drainage in a single day inner core tube takes place stops up, still can not be unimpeded through flushing, then can only change inner core tube, and increase infection chance.And novel three cover drainage tubes of the present utility model to keep an inner core not blocked, when another root inner core stops up, can use instead immediately, continue local drain.This three cover Tube Drains are strengthened the effect of drain, reduce hydrops and cause the chance of infection and change the chance that inner core tube causes infection, help patient's smooth recovery.
Description of drawings
Below in conjunction with drawings and embodiments this utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Wherein, 1,2 is inner core tube, and 3 is trocar sheath, and 4 is the circular port of inner core tube head end, and 5 is the circular port of trocar sheath head end, and 6,7 is the aperture that passes for inner core 1,2 on the trocar sheath.
The specific embodiment
Embodiment
As shown in Figure 1, a kind of peritoneal cavity drainage tube comprises inner core tube 1,2 and trocar sheath 3, and the inner core tube head end is provided with some circular ports 4, and trocar sheath 3 head ends are provided with circular port 5, and inner core tube 1,2 diameters are less than trocar sheath 3; Trocar sheath 3 has two be able to hold the aperture 6,7 that inner core tube 1,2 is passed through, and inner core tube 1,2 pierces into trocar sheath 3 by aperture 6,7 respectively.The internal diameter of inner core tube 1,2 is 2.5mm in the present embodiment, and external diameter is 3.5mm, and trocar sheath 3 is traditional double sleeve pipe (internal diameter 9mm, external diameter 10.5mm), the material of inner core tube 1,2 is silica gel tubes, and the material of trocar sheath 3 is whippy latex tubings, and trocar sheath 3 can tightly wrap inner core tube 1,2.
Excision is finished, and thoroughly after the hemostasis, inserts three cover Tube Drains of the present utility model.Wherein trocar sheath 3 connects saline bottle, can inwardly wash by water.Inner core tube 1 or 2 also connects saline bottle by " Y " shape pipe, also inwardly bath during beginning; Another inner core tube 2 or 1 connects negative pressure and outwards attracts, and can attract the normal saline and the Intraabdominal hydrops that pour.That root inner core tube of bath usefulness can not stopped up because of the direction of current.If attract that root inner core tube of usefulness drainage tube can be extracted before, just to stop up, then can be with its useless usefulness, use another root inner core tube instead and change into and connect vacuum suction, continue to keep the effect of abdominal cavity dual-casing drain.
This utility model is not limited to above-mentioned embodiment, no matter do any variation on its shape or structure, every drainage system that utilizes many inner core tube to prevent that drainage tube from stopping up fully all drops in the protection domain of the present utility model.
Claims (3)
1. peritoneal cavity drainage tube, comprise inner core tube and trocar sheath, inner core tube and trocar sheath head end have circular port, the inner core tube diameter is less than trocar sheath, it is characterized in that: described inner core tube is two, described trocar sheath has two be able to hold the aperture that inner core tube is passed through, and inner core tube pierces into trocar sheath by aperture respectively.
