[specific embodiment]
The technical solution of the utility model is further elaborated now in conjunction with accompanying drawings and embodiments, it is believed that art technology
It is clear for personnel.
As shown in Figure 1, a kind of myocardial protective liquid filling device, which is characterized in that
Including platform upper tube, it is perfused for patient:
Described upper tube connects 6% Rule cone joint by a hose both ends, and wherein the one 6% Rule circular cones of side connect
Head is used as body surface operating head, and the two 6% Rule cone joints of the other side are as the jointing with platform down tube；
Including platform down tube, cooling and preliminary filling is carried out under platform:
Platform down tube is wholy set in operating table in the following, described down tube includes the three 6% Rule circles docked with platform upper tube
Taper joint, the three 6% Rule cone joint are connected by hose with the first port of the first threeway, first threeway
Second port enters liquid stream road with first and connects, and first enters in liquid stream road to set cooling structure, so that the fluid temperature in loop is kept
In 4 DEG C of temperature, the third port of first threeway enters liquid stream road with second and connects, and described second enters the liquid inlet on liquid stream road
Two merging for entering liquid branch are realized further through the second threeway.
Described first enters liquid stream road, by needle for inserting bottle, the pump line branch of heart-lung machine, cooling coil, with exhaust apparatus
Two pass to and hose composition, liquid is via needle for inserting bottle and hose followed by pump line branch, cooling coil, the band of heart-lung machine
The two of exhaust apparatus lead to the second port until the first threeway.
The cooling coil structure is made of the coiling of several dish type cooling tubes, and it is mixed that 0 DEG C of ice water is set in the cooling coil
Object is closed, so that the fluid temperature in loop is maintained at 4 DEG C of temperature.
Using 4mm coil pipe cooling technology, cooling pipe tube wall is thinner more smooth, increases cooling pipe and contacts with cooling medium
Face increases, and cooling efficiency is high.Using coil arrangement, keep cooling effect more significant.

Pipe composition, liquid is via needle for inserting bottle and hose until the second threeway.
Platform upper tube and platform down tube shorten hose length, and hose length is shorter, is connected respectively with different tube diameters, reduces preliminary filling
Amount reduces patient blood dosage；The internal diameter of hose is small, and minimum diameter reaches 2.2mm, to achieve the effect that pipeline preliminary filling is small；Pipe
The dimensional accuracy in road is higher, so that blood controls more accurate with the ratio for stoping jumping liquid.Product size is controlled, makes priming volume more
It is small.
Blocking folder, the switch for blocking folder i.e. as every flow path, control switch setting are equipped on each flow path
Position is reasonable, and user can stop or start as needed at any time to be perfused.
The device that myocardium protecting liquid is perfused is the essential tool of cardiac operation under direct vision, clinically requires cooling efficiency
Fastly, few with blood, use is safe.In specifically used:
Device for casting is divided into blood vessel, pump line, cooling coil, intrusion pipe, several parts of crystal perfusion liquid pipe etc., pump line, cold
But coil pipe connects composition loop with crystal perfusion liquid, and cooling and preliminary filling is carried out under platform, by into blood vessel and intrusion pipe to patient into
Row perfusion.Crystal perfusion liquid is recycled in the loop by pump line, is needed amount to be used according to patient, is configured the ratio of crystal and blood
Example is 1:4, is performed the operation since perfusion pipeline injection patient's aortic root makes cardiac arrest after being sufficiently mixed.
Wherein the hose divided by purposes into blood vessel and intrusion pipe, and pump line be only it is a kind of more than conventional hoses elasticity
Better pipe shortens hose length and different tube diameters, first is that for the structure of cooperating equipment, second is that in order to reduce preliminary filling
Amount, the priming volume i.e.: before Cardiopulmonary Bypass, all external pipelines, oxygenator, artery filter all have to be filled with liquid
It is full of, to exclude gas therein, this process is known as extracorporal circulatory system preliminary filling, and required liquid is known as priming fluid, the use of priming fluid
Amount is priming volume.The blood of volume for having always and being equal to priming volume is present in pipeline, this part blood cannot participate in body
Interior circulation, so this amount is smaller better to human body.
