Abstract
The utility model relates to an intra-abdominal left ventricle assisting pump belonging to the technical field of medical appliances. The assisting pump structurally comprises a left atrium drainage tube, a pump case and an artificial blood vessel, wherein the upper part of the pump case is connected with the left atrium drainage tube in a sealing manner, one inner side of the pump case is provided with a haematodocha arranged on an inner wall of the pump case by a seal fixator, one side of the pump case is provided with an air passage branch pipe connected with a connecting pipe, the connecting pipe is connected with a positive-negative pressure gas transducer, the upper end and the lower end in the pump case are respectively provided with an upper valve and a lower valve, the lower part of the pump case is connected with an elbow pipe in a sealing manner, and the elbow pipe is connected with the artificial blood vessel in a sealing manner. Through the arrangement of the haematodocha, the intra-abdominal heart assisting pump can realize good biocompatibility and can favorably prevent the blood coagulation phenomenon from occurring, and furthermore, under the control of the positive-negative pressure gas transducer, air displacement can be adjusted to properly lead the blood output volume of the pump, thereby preventing the injury of the blood corpuscles caused by excessive contraction of the haematodocha to lead the two walls to collide with each other.
Description
Technical field
This utility model relates to technical field of medical instruments, left ventricle donkey pump in specifically a kind of abdomen.
Background technology
General; acidosis and hyperpotassemia make that myocardial contractility weakens, myocardial depressant factor suppresses myocardial contractility, impaired, the bacteriotoxin of cardiac muscle; especially endotoxin can directly damage cardiac muscle; disease like this occurs through regular meeting in the clinical treatment of cardiology department; moreover the cardiac muscle that damages approximately needs about 7 days time could recover it to penetrate the blood function, just need penetrate the blood function by what auxiliary means provided heart the patient of this section in convalescent period.Auxiliary appliance under the prior art has pulsed, rotary, centrifugal and auxiliary blood pump etc., but in use its biocompatibility is not good for these equipment, and the appearance of blood coagulation phenomenon is arranged often, and the patient has rejection.This give to a certain extent heart disease treatment belt difficulty.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and left ventricle donkey pump in a kind of abdomen is provided.
The technical solution of the utility model realizes in the following manner, heart assisting pump in this abdomen, its structure comprises the left atrium drainage tube, pump case and artificial blood vessel, pump case upstream and left atrium drainage tube are tightly connected, side in the pump case is provided with haematodocha, haematodocha is arranged on the pump case inwall by seal holder, pump case one side offers the air flue arm, the air flue arm is connected with adapter, take over positive negative-pressure gas transmitter and be connected, upstream extremity and downstream in the pump case are respectively arranged with upstream valve and downstream valve, and pump case downstream and swan neck are tightly connected, and swan neck and artificial blood vessel are tightly connected.
Pump case is the elliposoidal pump case.
The upstream valve is identical with the direction of downstream valve.
The beneficial effect that this utility model is compared with prior art produced is:
Heart assisting pump can be realized excellent biological compatibility by being provided with of haematodocha in this abdomen, can be good at the generation of anti-hemostasis-coagulation phenomenon, and can regulate capacity by the control of positive negative-pressure gas transmitter and come appropriateness to give the blood discharge amount of pump, the excess shrinkage that so can prevent hemostatic bag is collided two walls and is damaged hemocyte.An output of heart assisting pump is 0～85mL in this abdomen, and the frequency of beating is per minute 40～140 times, and flow adjustment range is 0～12L, and clinical effectiveness is good, and is safe and reliable, easy to use, can bring positive effectiveness for cardiac treatment.
