Adopting blood exchange transfusion set utilizing blood carries out in blood transfusion procedure process, blood in pipe-line system may containing impurity such as blood clots, after having blood clot to enter dropping funnel 10 inner chamber, be easy to be deposited on drainage screen 11, reduce the filter capacity of drainage screen 11, even cause drainage screen 11 to block, the blood flow in the pipe-line system causing dropping funnel 10 follow-up reduces.Now, if extrude dropping funnel 10 by force, be easy to make the impurity such as blood clot be forced through drainage screen 11 and enter in the follow-up pipe-line system of dropping funnel 10, finally along with the blood of flowing enters in human body, thus harmful effect caused to transfusion safety.In order to ensure transfusion safety, can the structure of dropping funnel 10 be designed to as shown in Figure 9, dropping funnel 10 one end is fixedly connected with input pipe 101, the other end is fixedly connected with outlet tube 105, in dropping funnel 10 inner chamber, be fixedly connected with dividing plate 103, dropping funnel 10 inner chamber is separated into separate filter chamber 102 and collecting chamber 106 totally two inner chambers by described dividing plate 103; Dividing plate 103 fixedly mounts conduit 104, and described conduit 104 is by filter chamber 102 and collecting chamber 106 conducting.Described drainage screen 11 can heat seal mode be fixedly mounted in the inner chamber of dropping funnel 10 input, and namely drainage screen 11 is fixedly mounted in filter chamber 102, and drainage screen 11 is between input pipe 101 and dividing plate 103.
As shown in Figure 9, after having the fluids such as blood to enter dropping funnel 10 from input pipe 101, first, by drainage screen 11, the fluid entered in filter chamber 102 is filtered, if contained not by the Large stone impurity of this drainage screen 11 in fluid, such as, in transfusion procedure, enter the blood clot that may contain Large stone in the blood of dropping funnel 10 inner chamber; In the infusion process of the higher protein-based fluid of viscosity, also earnest may be sunk containing the protein of Large stone in protein-based fluid, these will not be deposited on drainage screen 11 by the Large stone impurity of this drainage screen 11, the mesh of drainage screen 11 is easily caused to block, the filter capacity of drainage screen 11 is declined, causes the output flow of dropping funnel 10 to reduce, even cause in the follow-up pipeline of dropping funnel 10 and stop, have a strong impact on transfusion efficiency, and certain safety problem may have been brought.The fluid that can enter in filter chamber 102 enters in collecting chamber 106 through after conduit 104, outputs in the follow-up pipeline outside dropping funnel 10 eventually through outlet tube 105.
If the Impurity deposition amount on drainage screen 11 is too much, the output flow of dropping funnel 10 will greatly reduce, and even not export, and such as, during blood transfusion, the blood clot in blood is deposited on drainage screen 11 and causes drainage screen 11 to block.In this case, operator suitably can extrude the filter chamber 102 on dropping funnel 10, after filter chamber 102 pressurized shrinks, be deposited on the impurity such as the blood clot on drainage screen 11 will move upward, namely the direction of motion of the impurity such as blood clot is by contrary with the proper flow direction of fluid, thus force the impurity such as blood clot and drainage screen 11 to be separated from each other, recover the filter capacity of drainage screen 11, make the output flow of dropping funnel 10 recover normal.Because filter chamber 102 is after pressurized shrinks, the direction of motion being deposited on the impurity such as the blood clot on drainage screen 11 is contrary with the proper flow direction of fluid, therefore, the impurity such as blood clot can not be forced through drainage screen 11 and enter into collecting chamber 106, thus ensure that the impurity such as blood clot can not be exported by outlet tube 105, and finally enter into human body along with fluids such as blood, ensure that the reliability of transfusion, safety.Drainage screen 11 wherein can be designed to funnel-form, its relatively large end is arrival end, and the opening direction of arrival end is back to dividing plate 103, its relatively small end be the port of export, and the port of export is near dividing plate 103, so not only can increase the filter capacity of drainage screen 11, and the holding capacity to impurity such as blood clots can be improved, enhance the reliability of dropping funnel 10, safety.
The housing of described dropping funnel 10 preferably adopts TPE materials processing molding, dropping funnel 10 so not only can be made to have high transparent and extruding resilience, be convenient to when infusing, clearly to observe dripping of conduit 104 output count, improve infusion safety, and, also make dropping funnel 10 can Rapid reset after compressive deformation, ensure that dropping funnel 10 inner chamber has certain infusion pressure.In addition, after dropping funnel 10 uses, when needing to carry out waste treatment, even if carry out burning disposal, also can not produce the harmful substances such as hydrogen chloride, bioxin gas, thus be conducive to the environmental protection in dropping funnel 10 burning disposal process.
Between described dividing plate 103 and dropping funnel 10 housing, between input pipe 101 and dropping funnel 10 input, between outlet tube 105 and dropping funnel 10 outfan, between dividing plate 103 and conduit 104, both medical high polymer binding agent close adhesion can have been adopted integral, also can realize integrated molding by Mould Machining to connect, to reduce the production cost of dropping funnel 10.Described input pipe 101, outlet tube 105, dividing plate 103 and conduit 104 also preferably adopt TPE materials processing molding, so not only machine-shaping is easy, also be easier to realize close adhesion by medical high polymer binding agent, guarantee bonding strength is reliable, and the harmful substances such as hydrogen chloride, bioxin gas can not be produced in the burning disposal of dropping funnel 10, thus be conducive to environmental protection.
To sum up, owing to the second perforator 4 that blood adopts blood exchange transfusion set being arranged the inlet channel 42 of through puncturing head 44, and one-way air inlet film 48 is set in inlet channel 42 porch, therefore, blood in the present embodiment adopts the aerofluxus branch road that blood exchange transfusion set no longer needs independent configure band air filter, avoid the generation because of improper the caused pipeline discounting of aerofluxus shunt operations or air filter leakage situation, what improve blood adopts defeated efficiency, and effectively avoid blood to adopt pollution in defeated process, ensure that blood adopts defeated safety, reliability.Meanwhile, after blood transfusion completes, by operating the second perforator 4 and the blood remained in Blood transfusion tubeline can be rinsed well by liquid stopping clamp 2 easily, and make it to enter human body, thus decrease the waste of blood resource.In addition, blood adopts the first connecting hose 3, second connecting hose 5, the 3rd connecting hose 8, the 4th connecting hose 9, the 5th connecting hose 13, the 6th connecting hose 15, the 7th connecting hose 16 and helmet 18 in blood exchange transfusion set, TPE forming materials can be adopted, whole pipe-line system is not only made to have high transparent, be convenient to observation when adopting blood transfusion, improve the safety of adopting blood transfusion, and, adopt after blood exchange transfusion set uses at blood, even if carry out burning disposal, also can not produce the harmful substances such as hydrogen chloride, bioxin gas, thus be conducive to environmental protection.
In transfusion procedure, if the drainage screen 11 in dropping funnel 10 deposits too much when not causing drainage screen 11 that blocking occurs by the Large stone impurity of this drainage screen 11, operator suitably can extrude the filter chamber 102 on dropping funnel 10, make to be deposited on the impurity such as the blood clot on drainage screen 11 towards moving in the opposite direction with blood proper flow side, the impurity such as blood clot and drainage screen 11 is forced to be separated from each other, thus recover the filter capacity of drainage screen 11, make the output flow of dropping funnel 10 recover normal; Meanwhile, drainage screen 11 can not be forced through owing to being deposited on the impurity such as blood clot on drainage screen 11 and entering into collecting chamber 106, guaranteeing that the impurity such as blood clot can not output in human body, thus effectively ensure that reliability, the safety of blood transfusion.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, it should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
