The utility model has the advantages of reasonable design, simple structure, convenient operation, favorable heat exchanging effect, etc. and can be popularized and applied in clinical work.
Description
This utility model belongs to be imported medium in the human body or is passed to apparatus on the human body, is specifically related to and to the transfusion set of medical attraction or pumping tool.
Carrying out open heart operation with extracorporeal circulation, often adopting cardiac arrest to carry out the intracardiac surgery operation, cardiac arrest must be brought the heart ischemia anoxia, causes serious myocardial damage, so that operative failure.For this reason, carrying out effective myocardial protection during cardiac arrest is the operation key of success.
The patent No. is 97239459.1, denomination of invention is the Chinese patent of " disposable myocardium protecting liquid filling apparatus "; linked, link by drain pipe and Y-pipe by feed tube and reservoir by heat exchanger, Y-pipe is by following also pipe and the reservoir formation that links.This protection perfusion device is not provided with pressurizer between heat exchanger and reservoir, can only rely on liquid level difference that blood and other liquid are transported in patient's body.This protection perfusion device is not provided with register in addition; although blood and liquid can be lowered the temperature by heat exchanger, 25 ℃ blood and liquid be dropped at short notice 8 ℃ very difficult, particularly in hot season in summer; atmospheric temperature can't realize more than 35 ℃ at all.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and the cardioplegic solution device for casting of a kind of reasonable in design, simple in structure, easy and simple to handle, good effect of heat exchange, the quick blood transfusion and infusion that can pressurize is provided.
For achieving the above object, the solution that this utility model adopts is: it comprises liquid storing bag, heat exchanger, Y-pipe, heat exchanger links, links by drain pipe and Y-pipe by feed tube and liquid storing bag, Y-pipe links by circulation pipe and the gauge tap and the liquid storing bag that are installed on the circulation pipe, also connects the intrusion pipe that is provided with flow switch on Y-pipe.It also comprises the register that is arranged on the supercharger on the feed tube and is arranged on the heat exchange radiator periphery.Heat exchanger of the present utility model is the spiral tube exchanger of a surface irregularity.
Utility model is arranged on supercharger on the feed tube and also can be arranged on the drain pipe that heat exchanger and Y-pipe link.The register that this utility model is arranged on the heat exchanger periphery is the container that heat-conducting medium is housed in.Screw thread is processed or be manufactured with to the outer surface of this utility model spiral tube exchanger.
Supercharger of the present utility model is a blood pump.
This utility model is compared with disposable myocardium protecting liquid filling apparatus; on the feed tube between liquid storing bag and the heat exchanger, set up blood pump; can realize pressurizeing and transfuse blood fast and liquid; the Surface Machining of serpentine pipe heat exchange radiator has screw thread; increased heat exchange area; the heat exchange effect improves 30%, and it has advantages such as reasonable in design, simple in structure, easy and simple to handle, good effect of heat exchange, can promote the use of clinically.
Fig. 1 is the structural representation of an embodiment of this utility model.
Below in conjunction with drawings and Examples this utility model is further described, but this utility model is not limited to these embodiment.
In Fig. 1, present embodiment is made of liquid storing bag 1, circulation pipe 2, gauge tap 3, Y-pipe 4, intrusion pipe 5, flow switch 6, drain pipe 7, spiral tube exchanger 8, homoiothermic groove 9, feed tube 10, blood pump 11 connections, blood pump 11 is embodiment of supercharger, homoiothermic groove 9 is embodiment of register, and spiral tube exchanger 8 is embodiment of heat exchanger.One end and the liquid storing bag 1 of feed tube 10 link, the other end and spiral tube exchanger 8 link, can hold blood or other liquid in the liquid storing bag 1, blood pump 11 is connected on the feed tube 10 and with feed tube 10 and links, blood pump 11 can make its quick fluid interchange to the blood and the liquid pressurization of the spiral tube exchanger 8 of flowing through, and acceleration blood transfusion and infusion, the spiral tube exchanger 8 of present embodiment is made by stainless steel tube, on stainless steel tube, be processed with the crooked spirality of screw thread, the Surface Machining screw thread of present embodiment spiral tube exchanger 8, increased heat exchange area, heat exchange efficiency improves 30%.The also available aluminum pipe of the spiral tube exchanger 8 of present embodiment is made.Spiral tube exchanger 8 is placed in the homoiothermic groove 9, and 0 ℃ frozen water is housed in the homoiothermic groove 9, makes the blood of the spiral tube exchanger 8 of flowing through and the temperature of liquid reduce to 8 ℃, so that in the input patient body.Behind heart surgeon's knot bundle, need recovering beat of heart, when the blood of 35 ℃ ± 1 ℃ of patient's heart input and liquid, can in homoiothermic groove 9, hold 35 ℃～40 ℃ hot water, to blood and liquid heating.One end and the spiral tube exchanger 8 of drain pipe 7 link, the other end and Y-pipe 4 link, the other end of Y-pipe 4 and intrusion pipe 5 link, flow switch 6 is installed on the intrusion pipe 5, open flow switch 6, blood and liquid are input to patient's heart, Y-pipe 4 also has an end of an end and circulation pipe 2 to link, the other end of circulation pipe 2 and liquid storing bag 1 link, on circulation pipe 2, be connected with gauge tap 3, when not needing to patient's blood transfusion and liquid, or blood transfusion and amount of liquid are will reduce the time, close or turn down the flow switch 6 on the intrusion pipe 5, open the gauge tap 3 on the circulation pipe 2, from spiral tube exchanger 8 effusive blood and liquid through Y-pipe 4, circulation pipe 2 circulates in liquid storing bag 1.
The designer has provided second embodiment of the present utility model, and in the present embodiment, blood pump 11 is connected on the drain pipe 7 that spiral tube exchanger 8 and Y-pipe 4 link.The connecting relation of other parts and parts is identical with first embodiment.
According to above-mentioned principle, also can design the cardioplegic solution device for casting of another concrete structure.
