Abstract
The invention relates to a diaphragm pump head. The diaphragm pump head comprises a shell and a diaphragm fixedly arranged in the shell. A pressure inlet and outlet is formed in the portion, corresponding to one side of the diaphragm, of the shell, a blood inlet and outlet is formed in the portion, corresponding to the other side of the diaphragm, of the shell, one end of the blood inlet and outlet is communicated with the shell, and the other end of the blood inlet and outlet is simultaneously communicated with a blood inflow pipe and a blood outflow pipe. Through the structural arrangement, thrombi can be effectively avoided, the service life is prolonged, and use cost is reduced.
Description
Technical field
The invention belongs to medical instruments field, especially a kind of barrier film pump head.
Background technology
Barrier film pump head is a kind of blood pump of Novel bionic, can be widely used in cardiac operation and substitute the auxiliary device that heart carries out blood extracorporeal circulation and heart failure.Barrier film pump head comprises the barrier film installed in housing and housing, the housing of barrier film side is provided with pressure inlet/outlet pipe, the housing of barrier film opposite side is respectively arranged with into blood vessel and goes out blood vessel.Operation principle: impose positive/negative-pressure by pressure inlet/outlet pipe, barrier film is made to produce shake, blood is pumped into and pumps, existing barrier film pump head enters blood vessel and goes out blood vessel interval to arrange on housing, in the housing of barrier film pump head, easily produce circulation pause when blood pumps into and pump, thus easily make inner walls form thrombosis, affect the service life of barrier film pump head, improve application cost.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of barrier film pump head be provided, this pump head structure is simple, design science is reasonable, the formation of effective anti-tampon, improve service life, reduce use cost.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of barrier film pump head, comprises the barrier film be fixedly mounted with in housing and housing, and the housing that barrier film side is corresponding is shaped with pressure and imports and exports, it is shaped with blood and imports and exports on the housing that barrier film opposite side is corresponding.
And described pressure is imported and exported corresponding diaphragm center and is arranged.
And described blood is imported and exported corresponding diaphragm center and is arranged.
And described blood is imported and exported one end and is communicated with housing, the blood import and export other end is communicated with blood inlet pipe simultaneously and blood goes out pipe.
And described blood inlet pipe and blood go out on pipe to be separately installed with check valve.
And described barrier film is elastic deformation barrier film.
And described housing is spheroid or spheroid.
And described housing is rigid plastics.
The application of a kind of barrier film pump head in blood extracorporeal circulation system.
The application of a kind of barrier film pump head in blood pump system.
Advantage of the present invention and beneficial effect are:
1, this barrier film pump head, comprise the barrier film be fixedly mounted with in housing and housing, the housing that barrier film side is corresponding is shaped with pressure to import and export, it is shaped with blood and imports and exports on the housing that barrier film opposite side is corresponding, blood is imported and exported one end and is communicated with housing, and blood is imported and exported the other end and is communicated with blood inlet pipe and blood simultaneously and goes out pipe, and this vibrational power flow can the formation of effectively anti-tampon, improve service life, reduce use cost.
2, inventive shell is spheroid, pressure is imported and exported corresponding diaphragm center and is arranged, blood is imported and exported corresponding diaphragm center and is arranged, ensure that pressure turnover arrives the beeline of barrier film and the beeline of blood turnover, improve work efficiency, decrease circulation, and then reduce thrombosis risk.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of barrier film pump head, comprise the barrier film 6 be fixedly mounted with in housing 7 and housing, housing is rigid plastics.Barrier film is elastic deformation barrier film.The housing that barrier film side is corresponding is shaped with pressure and imports and exports 8, it is shaped with blood and imports and exports 4 on the housing that barrier film opposite side is corresponding.Pressure is imported and exported corresponding diaphragm center and is arranged.Blood is imported and exported corresponding diaphragm center and is arranged.Blood is imported and exported one end and is communicated with housing, and the blood import and export other end is communicated with blood inlet pipe 1 simultaneously and blood goes out pipe 2.Rounding is made in the blood import and export two side 5 connecting shell one end, and be conducive to the without hindrance flowing of blood, blood inlet pipe and blood go out on pipe to be separately installed with check valve 3.Housing is spheroid or spheroid.The present invention's housing shown in the drawings is spheroid, and pressure imports and exports the center being arranged on spheroid lower end, and blood imports and exports the center being arranged on spheroid upper end.
The application of a kind of barrier film pump head in blood pump system, this blood pump system also comprises positive/negative-pressure air accumulator, venous blood storage blood tank and oxygenator, and the pressure of this barrier film pump head is imported and exported and connected positive/negative-pressure air accumulator, blood inlet pipe is communicated with venous blood storage blood tank, and blood goes out pipe and is communicated with oxygenator.When using this system, because turnover blood port uses same one end, and being placed in haemocoele center and becoming 90 degree with barrier film, so do not produce blood backflow at work, thus avoiding the formation of thrombosis, pump blood efficiency is in most ideal position simultaneously.
The application of a kind of barrier film pump head in blood extracorporeal circulation system.Also comprise positive/negative-pressure air accumulator, venous blood storage blood tank and oxygenator, the pressure of this barrier film pump head is imported and exported and is connected positive/negative-pressure air accumulator, and blood inlet pipe is communicated with venous blood storage blood tank, and blood goes out pipe and is communicated with oxygenator.
