Abstract
The invention discloses a tip-stiffened drainage tube formed by welding two conduits which have same material and different hardness, wherein the Shore hardness of the tip part is 60D-75D, and the Shore hardness of a main tube body is generally 60A-100A. Annular drainage holes at the front end of the conduits are used for drainage; scale is printed on the conduits; and the material of the drainage tube can adopt PE (Poly Ethylene), PVC (polyvinyl chloride), PU (polyurethane) or nylon elastomer. The tip-stiffened drainage tube successfully solves the problems that a patient feels painful and suffers from internal body tissue necrosis due to compression, which are caused by high hardness of a conventional drainage tube in clinical use, or the hardness is too low to bear the inserting resistance, so that the conventional drainage tube can not enter into the coelom. The invention aims to provide the tip-stiffened drainage tube with the advantages of simple technology and procedure, reasonable design, safety and reliability and the like.
Description
Technical field
The present invention relates to a kind of catheter, particularly relate to a kind of drainage tube of most advanced and sophisticated stiffened.
Background technology
Drainage tube is used for gas or the liquid in the wounds such as drain thoracic cavity, abdominal cavity, encephalocoele or gastrointestinal tract in the clinical treatment, and common and puncture needle uses simultaneously.Puncture needle passes drainage tube and front end stretches out drainage tube during use, and the two thrusts body cavity synchronously, extracts puncture needle subsequently out, with the drainage tube drain that stays in the body.
These drainage tubes mostly are latex or silica gel material manufacturing.Because will stay for a long time in torso model or the abdominal cavity, for convenience of patient activity, so require quality soft.But after the thinner and puncture needle of the most tube walls of this type of drainage tube entered human body, tube wall holds can't stand advance resistance, is difficult to enter in the body synchronously with puncture needle.So, have to use drainage tube thicker, that quality is hard sometimes in clinical.But tube wall is very thick and stiff usually for this type of drainage tube, can't turn when putting into thoracic cavity or abdominal cavity, and patient's action is very painful.Can oppress surrounding tissue when putting into abdominal cavity or gastrointestinal tract in addition, easily cause and organize the pressurized ischemic necrosis, complication such as intestinal leakage occur.
Summary of the invention
The invention provides a kind of deficiency that can solve in the above use, have the drainage tube of the most advanced and sophisticated stiffened of advantages such as process is simple, reasonable in design, safe and reliable.
The present invention is achieved through the following technical solutions: material is identical and conduit weldings that hardness is different form by two kinds for the drainage tube of most advanced and sophisticated stiffened, and wherein the shore hardness of tip portion is 60D-75D, and the shore hardness of main body is generally 60A-100A.The circular conduction hole of catheter proximal end is used for drain, is printed on scale on the conduit.The material of drainage tube can be selected PE, PVC, PU or nylon elastomer for use.
Compared with prior art, beneficial effect of the present invention is:
1, process is simple.Promptly can be made into the drainage tube of firmness change by fusion joining process, tip and the quality softer body higher by quality constitute.
2, reasonable in design, safe and reliable.Most advanced and sophisticated and the gentle body of drainage tube stiffened, patient's misery and the necrosis of in-vivo tissue pressurized of having avoided drainage tube integral hardness height to cause have smoothly also avoided the hardness of body to hang down the problem that is difficult to bear the insertion resistance and can't enters body cavity.
Description of drawings
Fig. 1 is the drainage tube product sketch map of the most advanced and sophisticated stiffened of the present invention.
Fig. 2 is the drainage tube front end detail view of the most advanced and sophisticated stiffened of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
Shown in Figure 1 is the drainage tube of most advanced and sophisticated stiffened, is made by PU, and wherein most advanced and sophisticated 1 hardness is 70D, and main body 2 hardness are 80A, and most advanced and sophisticated and body is to extrude the back welding respectively to form.Catheter proximal end has three round holes 3 to be conduction hole, is responsible for the drain of liquids and gases in the body.
Shown in Figure 2 is the drainage tube front end detail view of most advanced and sophisticated stiffened, and in clinical use, puncture needle 4 passes drainage tube, and syringe needle stretches out drainage tube.
Claims (1)
1. the drainage tube of a most advanced and sophisticated stiffened is characterized in that, described drainage tube is formed by two kinds of different conduit weldings of material same rigidity, and wherein the shore hardness of tip portion is 60D-75D, and the shore hardness of main body is generally 60A-100A.
