From twentieth century since the forties, the central vein catheter art is used clinically in a large number, central venous puncture is put pipe at monitoring center's venous pressure (Central Venous Pressure, CVP), maintain the aspects such as blood volume and total parenteral nutrition (Total Parenteral Nutrition, TPN) and obtain clinical practice widely.
Be a kind of important method of modern monitoring and treatment through the deep vein puncture central vein catheter, by monitoring center's venous pressure, can understand patient's circulating blood volume and cardiac function, in order to guiding treatment and assessment curative effect; Massive hemorrhage, hypovolemic shock are rescued in the quick blood transfusion transfusion; Can also carry out the outer central vein nutrition of full intestinal etc. by central venous catheter.
Current, the central vein catheter art not only is widely used in Anesthesia Department, especially at intensive care unit (Intensive Care Unit, ICU), it is the important means of measuring center venous pressure and long-time fluid infusion monitor treatment, and other section office as: emergency department, department of general surgery etc. use also more.And the clinical practice of everything is all to be completed by central venous catheter (Central Venous Catheter, CVC).
Central venous catheter is for clinical transfusion, blood transfusion and monitoring center's venous pressure, its structure as shown in Figure 1, the conduit Connection Block is provided with fixing hole, body needs usually with stitching thread skin puncture A/C after inserting blood vessel, the one, troublesome poeration, need very skilled, clever doctor to operate; The 2nd, skin suture can produce wound, easily causes the invasion of antibacterial, causes infection, thereby affects the normal indwelling of conduit.
The utility model content
For solving problems of the prior art, for central venous catheter sew application trouble and easily antibacterial infection, this utility model provides a kind of fixture for central venous catheter of simple to operate and good fixing effect, on the skin that this fixture is directly pasted, not there will be the problems such as infection of sewing up and causing, practical.
A kind of fixture for central venous catheter, comprise pad pasting and base, also comprise a holding piece, described pad pasting is between base and holding piece, holding piece is provided with the locating dowel that runs through described pad pasting and base and coordinate with fixing hole on central venous catheter, and described base is provided with the anticreep parts that prevent that locating dowel breaks away from from fixing hole.
Central venous catheter, comprise main pipe, a conduit and the conduit Connection Block that is positioned at both joining places, and the quantity of a conduit is generally 1～3, and the relative both sides of conduit Connection Block respectively are provided with a fixing hole.Existing central venous catheter adopts to sew up and fixes, and the stitching thread that passes fixing hole is fixed on the conduit Connection Block on skin.
In this utility model, a kind of fixture for central venous catheter has been proposed, on the skin that this fixture is pasted by pad pasting, pad pasting is between base and holding piece, locating dowel on holding piece can be passed fixing hole, anticreep parts on base prevent that locating dowel breaks away from fixing hole, reaches the purpose of fixed center venous duct.
As preferably, described base is provided with the storage tank of the conduit Connection Block of placing central venous catheter.
During the fixed center venous duct, the conduit Connection Block is located in the storage tank of base, for limiting the position of conduit Connection Block, simultaneously, can rationally control the thickness of whole fixture, promotes comfort.
As preferably, described locating dowel and base interference fit.
In the technical program, locating dowel and base interference fit, make holding piece and base pinch be close to film, also can prevent that base from coming off from locating dowel, promotes the convenience in use procedure.
As preferably, the thickness of described holding piece is 0.5～2mm.
The thickness effect pad pasting of holding piece and the laminating degree of skin, holding piece is too thick, and the pad pasting at its edge and the gap of skin are larger, affect the sticking effect of pad pasting.
As preferably, described locating dowel is with the hole enlargement head of spheroidal, and described anticreep parts are the buckle closure be connected with base, and described buckle closure is provided with the locating hole passed for the hole enlargement head.
Locating dowel is through after fixing hole, position that can only the A/C Connection Block, also there is the risk broken away from from locating dowel in the conduit Connection Block, therefore, set up the buckle closure be connected with base, on this buckle closure, offer locating hole, the hole enlargement head of locating dowel is through after locating hole, with the locating hole interference fit, with the position of A/C Connection Block.
Described buckle closure is connected with described base by flexible sheets.
For strengthen buckle closure fasten and switching process in motility, make to be connected by flexible sheets between buckle closure and base convenient operation.
Described pad pasting middle part is provided with the U-shaped breach.
After pad pasting sticks on skin, main pipe is located in the U-shaped breach of pad pasting, prevents that main pipe from affecting the stickup fastness of pad pasting, makes pad pasting maintain the longer stickup phase.
This utility model is simple to operate, practical, and good fixing effect directly sticks on fixed center venous duct on skin during use, not there will be the problems such as infection that cause of sewing up.
The accompanying drawing explanation
The structural representation of venous duct centered by Fig. 1.
