Abstract
The utility model discloses a rotor pump for a medical device, wherein a blood outlet and a blood inlet are formed in the upper end and the lower end of a pump body; the blood outlet takes the shape of a horn mouth; a rotation stopping rib is arranged on the inner wall of the blood outlet; the blood outlet is communicated with a pump cavity through an L-shaped speed reduction tube; a rotor spindle is mounted in the pump cavity through a bearing pedestal and connected with a motor and a control circuit; helical blades are distributed on the rotor spindle. According to the utility model, the L-shaped design of the blood outlet of the rotor pump, the rotation stopping structure, hydraulic conversion and the layout of the helical blades of the rotor designed through fluid dynamics can reduce disturbance of blood and prevent the thrombi.
Description
Technical field
The utility model discloses a kind of medical apparatus rotor pump, belongs to medical instruments field.
Background technique
Existing Medical Instruments is " heart-lung machine ", and it is will flow into outside the venous blood lead body of heart, carries out oxygen and carbon dioxide exchange, through temperature regulation with after filtering, the device that in defeated ex vivo, the life of artery is supported.But the widely used cabinet type heart-lung machine in Hospitals at Present openheart surgery chamber has volume large, weight is large, needs the shortcoming of ABAP Adapter.Therefore, this heart-lung machine can not, out of doors without using under the ABAP Adapter condition, also can't be gone along with an army and use on ambulance or in wartime.The most use traffic meter of these cabinet type heart-lung machines is controlled rotating speed, and its shortcoming is complex structure, is unfavorable for the long steady running of blood pump, operation inconvenience.Experiment showed, that accurately, computer just can calculate flow automatically according to rotating speed so if motor speed is stable when the blood pump that drives blood flow is determined, thereby use traffic meter not.
Summary of the invention
The utility model provides a kind of medical apparatus rotor pump, can be assemblied on life recovery medical assistance instrument and replace existing flowmeter, has the characteristics such as simple in structure, easy to use, that energy consumption is low.
the disclosed a kind of medical apparatus rotor pump of the utility model, its technical solution is as follows:the two ends up and down of the pump housing are provided with outflow opening and inflow entrance; Outflow opening is the horn mouth shape, and its inwall is provided with resistance and revolves muscle; Outflow opening is communicated with pump chamber by " L " type deceleration tube; Rotor shaft is connected in pump chamber and with motor and control circuit by bearing holder device, is distributed with helical blade on rotor shaft.
good effect of the present utility model is:
The sue and labour device of blood samples of patients of driving adopts rotor pump structure, by control, make its motor speed accurate, take full advantage of principle of hydrodynamics, make blood obtain power in smooth environment, reduce as far as possible because rotor rotates the impact brought to blood, reduce the damage to blood, reduced thrombotic possibility." L " type design of rotor pump outflow opening, structure is revolved in resistance, the hydraulic pressure conversion, the layout of hydrokinetics design rotor blade, can reduce the disturbance of blood, the formation of anti-tampon.The utility model can be to because cold and the sign patient's that loses one's life blood is slowly heated, and suitable oxygenate (drowning person has reduced the oxygenate function because of lung's immersion), just can make patient slowly recover from " hibernation " and come, " coming back to life ".Saved those are misdiagnosed as " dead " person life because of cardiac arrest.
The accompanying drawing explanation
Fig. 1: the utility model rotor pump structure generalized section;
Fig. 2: the utility model rotor pump schematic perspective view;
In figure, 1, resistance revolves muscle; 2, outflow opening; 3, the pump housing; 4, pump chamber; 5, " L " type deceleration tube; 6, rotor shaft; 7, blade; 8, inflow entrance; 9, bearing support; 10, motor and control circuit.
Embodiment
Shown in Fig. 1, the two ends up and down of the pump housing 3 of the present utility model are provided with outflow opening 2 and inflow entrance 8; Outflow opening 2 is the horn mouth shape, makes hydraulic pressure in rotor pump from large to small, reduce the disturbance of blood, the formation of anti-tampon; Outflow opening 2 inwalls are provided with four resistances of arching upward and revolve muscle 1, and each is separated by 90 °, can reduce the rotation of blood when flowing out rotor pump; Outflow opening 2 is communicated with pump chamber 4 by " L " type deceleration tube 5, further reduces the disturbance of blood, the formation of anti-tampon; Rotor shaft 6 is connected in pump chamber 4 and with motor and control circuit 10 by bearing support 9 devices, be distributed with spiralling blade 7 on rotor shaft 6, blade 7 areas become large along rotor shaft 6 gradually by little, blade 7 distance between the upper and lower is also to become gradually large by little, blood is accelerated gradually, reduce equally the disturbance of pump inner blood, prevented the formation of thrombus.
The utility model rotor pump characteristics are: rotor directly drives blood flow, drive the energy consumption less of blood flow, thereby can select small motor to promote flowing of blood, make portable-type life recovery function limited battery-operated under, realize as much as possible running for a long time.
