Abstract
The utility model relates to a sub-low temperature extracorporeal circulation device, which is used in the treatment courses of the physical temperature reduction of high-heat patients. The sub-low temperature extracorporeal circulation device is mainly composed of a connecting catheter, a needle head, a pump inner catheter, a tension test pipe, an adjustor and a filter pipe to form a sealed circulating pipeline, wherein one end of an outlet of the connecting catheter is inserted and connected with the needle head, and the other end of the connecting catheter is connected with the filter pipe and is provided with the regulator between the needle head and the filter pipe; the other end of the filter pipe is connected with the outlet end of the pump inner catheter; the inlet end of the pump inner catheter is connected with the tension test pipe; the other end of the tension test pipe is connected with the inlet end of a catheter which is inserted and connected with the needle head, and is provided with the regulator between the tension test pipe and the catheter; a punching and blocking bypass which is connected with the needle head inserted and connected to the catheter is connected between the inlet end of the connecting catheter and the tension test pipe through a tee. The utility model is the disposable sealed circulating pipeline, is suitable for the sub-low temperature operating courses of extracorporeal circulation, can overcome the defect that a spliced pipeline of the present infusion tube is easy to result into pollution and increase patients' infection rate, and avoids resource waste caused by making use of a hemodialysis tube.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, particularly a kind of inferior cryotron outer circulation device that is used for hyperpyretic patient Physical temperature-lowering therapeutic process needs.
Background technology
The hyperpyretic patient, especially the central high fever patient that cause for a variety of causes adopt the physics method to carry out the inferior K cryogenic treatment of extracorporeal circulation usually.In operating process,, easily pollute and then increase the patient infection rate because the extracorporeal circulation pipeline that uses is with the tube for transfusion splicing; Sometimes also use the dedicated line that uses in the hemodialysis operation,, cause the wasting of resources again because the hemodialysis pipeline branch road is too many.Demand developing a kind of inferior cryotron outer circulation device that is used for hyperpyretic patient Physical temperature-lowering therapeutic process needs in clinical urgently.
The utility model content
The purpose of this utility model is to overcome the problem that exists in the above-mentioned background technology, and a kind of inferior low-temperature operation, aseptic, convenient of extracorporeal circulation that is applicable to is provided, and reduces patient infection's inferior cryotron outer circulation device.
For realizing the purpose of this utility model, the technical solution that is adopted is: a kind of inferior cryotron outer circulation device, mainly by connecting duct, syringe needle, the pump inner catheter, the tension test pipe, the closed circulation line that actuator and filter tube are formed, outlet one end of described connecting duct is plugged with syringe needle, its other end connects filter tube and be provided with actuator between it, the filter tube other end is connected with the port of export of pump inner catheter, the entrance point of pump inner catheter is connected with the tension test pipe, and the tension test pipe other end is connected with the duct inlet end of grafting syringe needle and is provided with actuator between it; Between connecting duct entrance point and tension test pipe, be connected with the stifled bypass of dashing of grafting syringe needle on the conduit by threeway.
Described is the conduit that is plugged with syringe needle and is connected successively with observation window, quantifier at entrance point towards stifled bypass, is being respectively equipped with actuator between observation window and the quantifier and on the conduit between threeway and the quantifier.
The beneficial effects of the utility model are: this utility model is disposable closed circulation line, be applicable in the inferior low-temperature operation process of extracorporeal circulation, can overcome the deficiency that present use tube for transfusion splicing tubes Louis pollutes and then cause the patient infection rate to increase, avoid the wasting of resources that utilizes hemodialysis tube to cause, aseptic, save time, laborsaving, economize on resources.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of this utility model.
The specific embodiment
Below in conjunction with accompanying drawing a kind of embodiment of the present utility model is described in further detail.
As shown in the figure, a kind of inferior cryotron outer circulation device, mainly by connecting duct 12, syringe needle 1 and 14, pump inner catheter 10, tension test pipe 9, actuator 2 and 13 and filter tube 11 form, be the closed circulation line, outlet one end of described connecting duct 12 is plugged with syringe needle 14, its other end connects filter tube 11 and be provided with actuator 13 between it, filter tube 11 other ends are connected with the port of export of pump inner catheter 10, the entrance point of pump inner catheter 10 is connected with tension test pipe 9, tension test pipe 9 other ends are connected with conduit 12 entrance points of grafting syringe needle 1 and are provided with actuator 2 between them, the expansion of tension test pipe and subside and to reflect the vascular resistance situation, with indication blood circulation situation, being beneficial to medical personnel in time adjusts, filter tube 11 adopts existing blood exchange transfusion set to go up the filter tube that uses, and actuator can adopt liquid-stopping device commonly used when infusing.Between connecting duct 12 entrance points and tension test pipe 9, be connected with grafting syringe needle 8 on the conduit and dash stifled bypass, be respectively equipped with actuator 6 and 4 at observation window-Murphy's dropper 7 and quantifier-indicate on the conduit between the graduated transfusion bag 5 and threeway 3 and quantifier-indicate on the conduit between the graduated transfusion bag 5 with the graduated transfusion bag 5 of observation window-Murphy's dropper 7, quantifier-indicate is connected successively by threeway 3.By the dashing stifled bypass input liquid on the circulation line, can flushing line, blood clot is washed open, keep tube chamber unobstructed, utilize gageable transfusion bag and actuator to control and enter intravital amount of liquid, to keep discrepancy amount balance.
During use, at patient's femoral vein double channel catheter is set, another name vein end and arterial end are divided in two chambeies, entrance point syringe needle 1 of the present utility model is inserted vein end, blood flow is through circulation line, the major part of circulation line all is positioned over (not shown) in the refrigeration plant (as ice water bucket), make mobile blood obtain cooling, cooling, again through blood pump (machine name: Blood Pump, the TOKYO JAPAN of manufacturer) (blood pump and pump inner catheter match by pump inner catheter 10, the pump inner catheter is embedded in the blood pump) pressurization, blood is fed back to femoral vein through port of export syringe needle 14 by arterial end, make patient body keep inferior low temperature state.
The above only is the preferred embodiment of the invention, is not the material and the structure of the invention are done any pro forma restriction.Every technical spirit according to the invention all still belongs in the scope of the invention technical scheme any simple modification, equivalent variations and modification that above embodiment did.
