Description
One, technical field
The utility model belongs to isolated heart (for the heart) save set, and particularly a kind of energy continues the save set to isolated heart (for the heart) perfusion preservation liquid.
Two, background technology
At present, heart transplant has become the effective ways of treatment heart disease at final stage, and the preservation effect of isolated heart (for the heart) directly affects the success rate of heart transplant operation.From mankind's heart transplant for the first time existing more than 30 year so far, the design of preserving liquid for the heart is ever-changing, but preserve almost no change of technology for the heart, " high potassium arrest, low temperature static are preserved " is the main method of preserving for the heart always, with the corresponding isolated heart of this method (for the heart) save set be the container of plastic sack and dress ice cube, isolated heart (for the heart) and preservation liquid thereof all are contained in the plastic sack, and the plastic sack that envelope ties places in the container that ice cube is housed.The weak point of said method and save set is: 1, can not provide necessary oxygen of myocardial metabolism and nutriment for isolated heart; 2, can't regulate the interior environment of cardiac muscle work, the acidic metabolite that cardiac muscle cell's anaerobic metabolism generates is piled up, and causes myocardial cell injury; 3, low temperature is preserved the activity of damage enzyme, increases the weight of the energy dyspoiesis; 4, can not monitor the preservation situation that supplies the heart.Therefore use above-mentioned save set, the preservation effect of isolated heart poor (transplanting back cardiac insufficiency incidence height), safe holding time short (4～6 hours).
Three, summary of the invention
The utility model provides a kind of energy to continue the save set that (for the heart) pours into preservation liquid to isolated heart at the deficiency that prior art exists, and to improve the preservation effect of isolated heart (for the heart), satisfies the needs of heart transplant operation.
The technical solution of the utility model is: according to the survival environment and the condition design save set of heart, this save set comprises heart and preservation liquid storing containers, the membrane lung that is provided with air inlet pipe and escape pipe, charge pump, is positioned at intrusion pipe, feed tube, drain pipe, the probe tube of heart and preservation liquid storing containers.One end of feed tube is connected with preservation liquid storing containers with heart, and the other end is connected with membrane lung; One end of drain pipe is connected with membrane lung, the other end be positioned at heart and be connected with the intrusion pipe of preserving the liquid storing containers; One end of probe tube is connected with membrane lung, and the other end is connected with preservation liquid storing containers with heart; Charge pump is installed in the pipeline of feed tube formation.Can form the closed circulatory system that can carry out gas exchange like this, make isolated heart (for the heart) from preserve liquid, absorb oxygen and nutriment, can keep the stable of the interior environment of cardiac muscle again.
For easy to use, prevent to pollute, direct suction heart of the blood of heart donor and the preparation of preservation liquid storing containers are preserved liquid, can be equipped with and get blood vessel, this is got blood vessel and is inserted into heart and preserves on the liquid storing containers, a part is positioned at container, and a part is positioned at outside the container.
For the ease of transporting and make the precipitation that produces in the cyclic process of preservation liquid fall into container bottom, can and preserving heart placement and preservation liquid filter element are set in the liquid storing containers at heart.
Pressure for the ease of monitoring and adjustment preservation liquid can be provided with pressure controller, and this pressure controller is connected with intrusion pipe with charge pump by pipe fitting.
Temperature for the ease of monitoring and adjustment preservation liquid can be provided with temperature monitor, and this temperature monitor is installed in heart and preserves in the liquid storing containers.
Heart and preservation liquid storing containers are combined by body and closure member, and body is made by plastics or glass, and body wall is the sandwich that single layer structure maybe can be installed the temperature adjustment device, and closure member is flexible cover or rigid cover plate.Membrane lung is made up of shell and installation many rows hollow fiber conduit in the enclosure; For the ease of transportation, the shell of membrane lung and heart and the body of preserving the liquid storing containers are the detachable combination that is connected, its combinatorial surface be complementary with the shape of heart with the corresponding combinatorial surface of preservation liquid storing containers body.
The using method of the lasting perfused hearts save set that the utility model provides: at first will preserve pack into heart and preserve the liquid storing containers of liquid, then will from the heart that donor takes out put into above-mentioned storing containers and with intrusion pipe with insert the isolated heart aortic root intrusion pipe is connected and can realizes the lasting preservation liquid that pours into of isolated heart.
The utlity model has following beneficial effect:
1, can continue perfusion to heart and preserve liquid, continue,, satisfy the energy demand of isolated heart (for the heart) when stopping jumping stably for isolated heart provides necessary oxygen of myocardial metabolism and nutriment.
2, keep cardiac muscle cell's homeostasis, create good condition for transplanting the back recovering beat of heart.
3, reduced of the damage of the acidic metabolite of anaerobic metabolism generation to the cardiac muscle cell.
4, isolated heart (for the heart) storage temperature can be adjusted by configuration temperature adjustment device, is not limited to lower temperature, thereby both needn't worries the energy deficiency that the metabolism increase causes, the energy deficiency that can avoid enzymic activity to descend and cause again.
5, can monitor the preservation situation of isolated heart (for the heart) and the situation of change of preserving liquid at any time.
6, preserve liquid and can be recycled, help reducing retain costs.
7, simple to operate, controllability is strong.
8, volume is little, convenient transportation.
