Abstract
The utility model relates to a disposable blood extracorporeal circulation loop catheter. The disposable blood extracorporeal circulation loop catheter is in a double-layer tubular structure which is composed of a thermoplastic polyether urethane (TPU) material inner layer and a poly vinyl chloride (PVC) material outer layer in a composite mode. The TPU material inner layer is 0.05 millimeter to 0.4 millimeter thick, and the PVC material outer layer is 0.5 millimeter to 1 millimeter thick. The disposable blood extracorporeal circulation loop catheter is reasonable in structure and simple in composition, and a contact layer contacting blood and liquid drug is made of non-PVC materials. Especially the disposable blood extracorporeal circulation loop catheter is manufactured through a double-layer common extrusion method, and therefore the disposable blood extracorporeal circulation loop catheter is lower in cost compared to catheters made of pure TPU materials, is safer compared to catheters made of pure PVC materials, and is good in blood compatibility, the problem of blood contamination caused by heavy metal ions and plasticizer migration is avoided, and the disposable blood extracorporeal circulation loop catheter is higher in stability, safety performance and reliability.
Description
Technical field
This utility model belongs to medical instruments field, relates to disposable use blood extracorporeal circulating circuit conduit specifically.
Background technology
At present, general uremic patient, the double kidney disease of ZANG-organs people overwhelming majority need be kept and continue life through this mode of hemodialysis, and what the conduit in the disposable blood loop of in blood dialysis, using adopted is that the medical PVC resin manufacture forms.Polyvinyl chloride resin remaining with the course of processing in discharge VCM and have carcinogenecity; Plasticizer that soft pvc adds such as heavy metal such as calcium, the zinc ion etc. in DEHP and the heat stabilizer can move out, along with blood enters in the human body, bring potential harm to human body.According to bibliographical information, the plasticizer in the PVC goods can penetrate in the blood in the time of 4 ℃, and particularly DEHP very easily dissolves in blood, is dissolved with this type plasticizer in the blood and can causes hepatic lesions and atrophy of testis.The acute toxicity of plasticizer is very low, does not have the performance of acute poisoning, but its chronic toxicity is big, can cause that hepatic and renal function descends, erythrocyte reduces, and has mutagenicity and carcinogenecity.
Calendar year 2001 signature, persistence organic pollutant Convention of Stockholm (POPs pact) suggestion that came into force in 2004: it is harmful that products such as transfusion (blood) pipe of being processed by the PVC plastics, packaging bag, blood bag, respiratory mask, food bag are grown breeding to the mankind.All taking action in the U.S., European Union, Japan, Korea S, China Taiwan, with limiting the use of PVC as one of strategy of dioxin decrement.At present, developed country and regional new auxiliary and the new materials that stepping up to develop alternative DEHP plasticizer and PVC material such as the U.S., Europe and Japan.
Polyurethane elastomer (TPU) has excellent biological compatibility, blood compatibility, no various additives, is its major reason in medical field acquisition application, is the ideal material of medical catheter.Yet the hardness of medical Polyurethane Elastomer is bigger, and price is higher, and this two aspects reason has limited its application on disposable use blood circuit.
Summary of the invention
This utility model technical problem to be solved is the deficiency that overcomes above-mentioned prior art; Provide a kind of rational in infrastructure, form simple, with blood and medicinal liquid contact layer be non-PVC material; Safety property is high, the disposable use blood extracorporeal circulating circuit conduit that adopts double-layer coextrusion to go out to make.
The technical scheme that this utility model solves the problems of the technologies described above employing is: a kind of disposable use blood extracorporeal circulating circuit conduit; It is characterized in that: said conduit is by TPU material internal layer and the compounded double layered tubular structure of PVC material outer layer; The thickness of said TPU material internal layer is 0.05mm-0.4mm, and the thickness of PVC material outer layer is 0.5mm-1mm.
The said conduit of this utility model adopts double-layer coextrusion to go out the medical macromolecular materials manufacturing, need not any bonding agent in the middle of internal layer TPU material and outer PVC material two interlayers.The internal layer TPU material that contacts with blood can not react with blood.Against existing technologies, this utility model is rational in infrastructure, form simple, with blood and medicinal liquid contact layer be non-PVC material, cost is lower, the performance safety and reliability.Especially adopt double-layer coextrusion to go out to make; Reduce than simple TPU tubes of material cost; PVC tubes of material performance than simple is safer, and blood compatibility is better, has avoided the problem of the blood contamination that the heavy metal ion and the migration of plasticizer brings; Make that this disposable use blood circuit stability is higher, have more safety and reliability.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described further.
Fig. 1 is the structural representation of this utility model.
Label is among the figure: 1. internal layer, 2. skin.
The specific embodiment
As shown in Figure 1, a kind of disposable use blood extracorporeal circulating circuit of this utility model comprises main pipe and side conduit, they with some dropping funnel, injection threeway, DL lock-on connection, slip joint, wing formula lock-on connection with path of the bonding composition of Ketohexamethylene.
Said conduit is that the thickness of said TPU material internal layer 1 is 0.05mm-0.4mm by TPU material internal layer 1 and PVC material outer layer 2 compounded double layered tubular structures, and the thickness of PVC material outer layer 2 is 0.5mm-1mm.
The said conduit of this utility model is that double-layer coextrusion goes out tubing, need not any bonding agent in the middle of internal layer 1TPU material and outer 2PVC material two interlayers.The internal layer TPU material that contacts with blood can not react with blood.This utility model is rational in infrastructure, form simple, with blood and medicinal liquid contact layer be non-PVC material, cost is lower, performance is safe and reliable.Especially adopt double-layer coextrusion to go out to make; Reduce than simple TPU tubes of material cost; PVC tubes of material performance than simple is safer, and blood compatibility is better, has avoided the problem of the blood contamination that the heavy metal ion and the migration of plasticizer brings; Make that this disposable use blood circuit stability is higher, have more safety and reliability.
