The jam volume that is used for the shutoff of intestinal air fistula
Technical field
This utility model belongs to the surgical material field, relates to the jam volume for the shutoff of intestinal air fistula.
Background technology
Wound, serious abdominal cavity infection, gap, abdominal cavity syndrome and other abdominal part emergency cases etc. may cause abdominal cavity opening.The formation of intestinal fistula is the severe complications in open abdominal cavity, and this type of fistula is owing to lack surrounding soft tissue, and the spontaneous recovery probability is low, is called intestinal air fistula.Intestinal air fistula can appear in 25% abdominal cavity opening patient, and fatality rate is up to 42%.
The abdominal cavity opening patient wound surface that merges intestinal air fistula is subjected to continuing corrosion and the infection of outflow intestinal juice, and is also unbalance with Water-Electrolyte mostly.The treatment of intestinal air fistula is still based on the definitiveness operation at present.In this stage of waiting for the definitiveness operation, need control to spill intestinal juice to corrosion and the infection of open wound, the protection wound surface recovers enteral nutrition etc. early.At present, adopt means such as biological dressing, negative pressure irrigation and drainage, Fibrin Glue sealing, effect is unsatisfactory.
The utility model content
The purpose of this utility model is the above-mentioned defective at prior art, and a kind of jam volume for the shutoff of intestinal air fistula is provided.
The purpose of this utility model can be achieved through the following technical solutions:
Be used for the jam volume of intestinal air fistula shutoff, be rolled into tubular by jam, cylindrical sidewall is provided with the dismountable backguy that jam is fixed into tubular.
Wherein, described jam is made up of the net sheet of the tool elastic reaction of silica gel negative plate, silica gel negative plate internal layer.
Described silica gel negative plate is round or subcircular, and thickness is 0.1mm.
The net sheet of described tool elastic reaction is positioned at the silica gel negative plate middle part, and its size equates with silica gel negative plate or less than silica gel negative plate, material is polypropylene, to strengthen the tensile strength of jam.
The length of described jam volume is 4-6cm, must surpass the 3-5cm of fistula mouth diameter, can put into enteric cavity along the fistula mouth after curling, and the diameter of tubular is 0.8 ~ 1.2cm.
The radical of described backguy is two, and according to the diameter of fistula mouth, seam is worn jam, twines jam and becomes web-like, and it is fixing to be used for being hung.
Beneficial effect:
This utility model provides another cheap and good-quality treatment articles for intestinal air fistula patient.Out of shape according to fistula mouth size and intestinal tube, this utility model jam volume is positioned in patient's enteric cavity, the jam volume launches the back jam and is close to the enteric cavity inwall, thereby plays shutoff fistula mouth, the successional purpose of recovery intestinal, is similar to " inner cavity insulation " technology.After this utility model jam volume is placed successfully, intestinal air fistula mouth will not have intestinal juice and will flow out, the abdominal cavity opening wound surface is pollution-free, can make taking-up when sheet is stifled to last till definitiveness operation (stomach wall reconstruction+intestinal fistula excision reconstruction of digestive tract) always, for absorbing health invigorating by autodigestion, the patient provides guarantee, can be the patient and save a large amount of medical expenses, palliate the agonizing sufferings.This utility model is simple in structure, and is easily manufactured, and cost is low.
Description of drawings

Wherein, 1 is silica gel negative plate, and 2 is the net sheet of tool elastic reaction, and 3 is jam.
Fig. 2 jam volume perspective view
Wherein, 3 is jam, and 4 are backguy, and 5 are the jam volume, and L is the length of jam volume, and d is the diameter of tubular jam volume.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is described further.
Embodiment 1
A kind of jam volume 5 for the shutoff of intestinal air fistula, length L is 6cm, the diameter d of tubular is 1.0cm.Be rolled into tubular by jam 3, cylindrical sidewall is provided with the dismountable backguy 4 that jam 3 is fixed into tubular.Jam 3 is that the silica gel negative plate 1 of 0.1mm and the net sheet 2 that is positioned at the tool elastic reaction at silica gel negative plate internal layer center are formed by circular, thickness, is rolled into that the net sheet 2 of elastic reaction is positioned at internal layer behind the tubular, and silica gel negative plate 1 is positioned at skin.The radical of backguy 4 is two, and according to the diameter of fistula mouth, seam is worn jam, twines jam and becomes drum, and it is fixing to be used for being hung.It is dismountable with being connected of jam, when jam volume 5 being placed in the intestinal behind the appropriate position, only needing to extract out backguy 4 and jam volume 5 is opened be close to the enteric cavity inwall after jam launches, thereby play shutoff fistula mouth, recover the successional purpose of intestinal.
