[0002] Artificial pumps are usually used to provide power for blood flow in the patient's blood vessels. Artificial pumps in the prior art are mostly centrifugal pumps, which usually include a housing and a rotor disposed in the housing. The housing is generally conical with a larger upper portion and a smaller lower portion, and a vertical liquid inlet is formed at the upper end of the housing for blood to enter, and a radial liquid outlet is formed on one side of the lower portion of the housing. Blades are provided on the rotor. By driving the rotor, blood enters the housing from the liquid inlet under the action of the blades and flows out from the liquid outlet at a certain flow rate. The existing pump device still has the following problems when in use. The operating frequency of the pump cannot be synchronized with the patient's heart beat frequency, which can easily lead to insufficient or excessive blood supply, and also increase the burden on the heart.

[0008] Furthermore, a circle of glue is provided on the edge of the surface of one side of the heart rate sensor in contact with the skin. Beneficial Effects

[0009] When working at the same frequency as the heart, the heart rate sensor is attached to the heart position on the chest, and blood enters from the liquid inlet tube and into the interior of the filter chamber. When working, the electromagnetic component is energized to generate electromagnetic force. Under the action of the magnetic force, several electromagnetic components drive the prismatic pump cores to close and open toward the middle. When closing, blood is sucked into the interior of the filter chamber from the liquid inlet tube. At the same time, the blood inside the pump liquid chamber is squeezed out from the liquid outlet tube under the action of the pressure of the prismatic pump core.

When the heart rate sensor detects the heartbeat, the prismatic pump core is closed and opened synchronously, thereby reducing the burden on the heart and improving the treatment efficiency.

[0010] When the prismatic pump core is closing and opening, it is only necessary to control the energization of the coil of the corresponding electromagnetic component to achieve closing and opening. When closing, the magnetic field generated by the electromagnetic component on the upper side has opposite magnetic poles to the magnetic field generated by the electromagnetic component on the lower side, that is, the magnetic poles of the electromagnetic components on the upper and lower sides close to one end of the prismatic pump core are opposite, and the magnetic poles of the electromagnetic components on the same side are the same. When opening, the magnetic field generated by the electromagnetic component on the upper side has the same magnetic poles as the magnetic field generated by the electromagnetic component on the lower side, so that the upper and lower electromagnetic components attract each other, that is, the magnetic poles of the upper and lower electromagnetic components close to one end of the prismatic pump core are the same, so that the upper and lower electromagnetic components repel each other.

[0011] Compared with the prior art, the present invention, through the arrangement of the heart rate sensor and the pump body, enables the pump body to work at the same frequency as the heart frequency during operation, thereby reducing the burden on the heart, improving the treatment efficiency, and slowly restoring the vitality of the heart. Through the arrangement of the filter cavity and the filter body, the filter body can filter the blood clots in the blood, and the pump body can increase the pressure faster and to a greater extent than the existing pump body.

DETAILED DESCRIPTION

[0027] Please refer to Figures 1 to 13 ; This embodiment provides a pump device for cardiovascular surgery, referring to Figures 1 to 8 , comprising a shell 1, a pump body 4 is installed in the middle of the shell 1, a control panel 2 is provided on the upper surface of the shell 1, a rechargeable battery 5 is installed between the inside of the shell 1 and the gap between the pump body 1, the control panel 2 is connected to a heart rate sensor 3 for monitoring the heart beat frequency through a flying wire electrical signal, the pump body 4 comprises a prismatic pump body 401 installed in the middle of the shell 1, one end of the prismatic pump body 401 is fixedly connected with an inlet pipe 411 and an outlet pipe 412, The cross section of the prismatic pump body 401 is prismatic, the inner wall of the prismatic pump body 401 is integrally connected with a pump outer wall 402, the inner side of the pump outer wall 402 is provided with a pump middle wall 421, the inner side of the pump middle wall 421 is provided with a pump inner wall 422, the gap between the pump outer wall 402 and the pump middle wall 421 constitutes a filter cavity, the gap between the pump middle wall 421 and the pump inner wall 422 constitutes a drive cavity, the interior of the pump inner wall 422 forms a pump liquid cavity, the top and bottom of the pump liquid cavity are integrally connected with a pump inlet pipe 423 between the filter cavity, A prismatic pump core 404 is provided inside the driving cavity and is integrally connected and wrapped around the outer surface of the pump inner wall 422. A plurality of electromagnetic components 405 are evenly installed on the four side surfaces of the prismatic pump core 404. The heart rate sensor 3 controls the electromagnetic components 405 through the control board 2. A liquid inlet pipe 424 connected to the filter cavity is provided inside the inlet pipe 411. A liquid outlet pipe 425 connected to the pump liquid cavity is provided inside the outlet pipe 412. Flexible one-way mechanisms 426 are provided inside the pump inlet pipe 423, the liquid inlet pipe 424, and the liquid outlet pipe 425. In specific implementation, when working at the same frequency as the heart, the heart rate sensor 3 is attached to the heart position of the chest, and blood enters from the liquid inlet tube 424 and enters the interior of the filter chamber. When working, the electromagnetic component 405 is energized to generate electromagnetic force. Under the action of the magnetic force, the plurality of electromagnetic components 405 drive the prismatic pump core 404 to close and open toward the middle. When closing, blood is sucked into the interior of the filter chamber from the liquid inlet tube 424. At the same time, the blood inside the pump liquid chamber is squeezed out from the liquid outlet tube 425 under the action of the pressure of the prismatic pump core 404. When the prismatic pump core 404 is opened, the pressure of the prismatic pump core 404 at this time will squeeze the blood inside the filter chamber, so that the blood inside the filter chamber enters the pump liquid chamber from the pump inlet tube 423. When the heart rate sensor 3 detects the heartbeat, the prismatic pump core 404 is closed and opened synchronously, thereby reducing the burden on the heart and improving the treatment efficiency.

[0028] For further reference, Figures 2 to 10 A filter body 403 with a prismatic cross section is provided inside the filter cavity. The edges of both sides of the filter body 403 are connected to the outer walls of both sides of the pump middle wall 421. The top of the middle part of the filter body 403 is connected to the inner wall of the pump outer wall 402. The four surfaces of the filter body 403 are evenly provided with filter holes for filtering blood clots. In a specific implementation, the filtering surface of the filter body 403 is inclined inside the filter cavity, dividing the filter cavity area to which the inlet tube 424 and the pumping tube 423 are respectively connected. When the inlet tube 424 delivers blood into the filter cavity, the filter body 403 filters to filter out the thrombus in the blood, and allows the filtered blood to enter the pump cavity from the pumping tube 423.

[0029] Further, the pump outer wall 402, the pump middle wall 421, the pump inner wall 422, the pump inlet pipe 423, the liquid inlet pipe 424, the liquid outlet pipe 425 and the flexible one-way mechanism 426 are all made of artificial blood vessel materials; In the specific implementation, the artificial blood vessel material adopts the existing technology, so that the pump outer wall 402, the pump middle wall 421, the pump inner wall 422, the pump inlet tube 423, the liquid inlet tube 424, the liquid outlet tube 425 and the flexible one-way mechanism 426 are soft and deformable, and can be used to transport blood.

[0030] For further reference, Fig.13 The flexible one-way mechanism 426 is arranged in a cone shape, and a plurality of contraction grooves for contraction are provided on the outer wall of the cone of the flexible one-way mechanism 426, and a passage penetrating through both ends is provided in the middle of the flexible one-way mechanism 426; In a specific implementation, the flexible one-way mechanism 426 simulates the heart valve when controlling the one-way flow of blood. When blood passes through, the blood stretches the flexible one-way mechanism 426 from the inner and outer peripheries to allow the blood to pass through. When the blood flows back, the blood will deform at the cone of the flexible one-way mechanism 426, and the internal channel of the flexible one-way mechanism 426 will be closed, preventing the blood from flowing back.

[0031] Furthermore, the prismatic pump core 404 is made of a magnetizable material, and the electromagnetic member 405 includes an iron core 451, and a plurality of coils 452 are wound around the outer wall of the iron core 451, and a metal outer cylinder 453 is wrapped around the outer periphery of the coil 452, and the bottom end of the metal outer cylinder 453 is connected to the prismatic pump core 404 as a whole, and the top end of the metal outer cylinder 453 is fixedly connected to the pump middle wall 421; The prismatic pump core 404 is a thin sheet structure with a prismatic cross section, which can be closed in the middle or opened in the middle; In a specific implementation, when the prismatic pump core 404 is closed and opened, when closing, it is only necessary to control the energization of the coil 452 of the corresponding electromagnetic member 405 to achieve closing and opening. When closing, the magnetic field generated by the electromagnetic member 405 on the upper side has opposite magnetic poles to the magnetic field generated by the electromagnetic member 405 on the lower side, that is, the magnetic poles of the electromagnetic members 405 on the upper side and the lower side close to one end of the prismatic pump core 404 are opposite, and the magnetic poles of the electromagnetic members 405 on the same side are the same. When opening, the magnetic field generated by the electromagnetic member 405 on the upper side has the same magnetic poles as the magnetic field generated by the electromagnetic member 405 on the lower side, so that the electromagnetic members 405 on the upper side and the lower side attract each other, that is, the magnetic poles of the electromagnetic members 405 on the upper side and the lower side close to one end of the prismatic pump core 404 are the same, so that the electromagnetic members 405 on the upper side and the lower side repel each other. The prismatic pump core 404 can be quickly closed and opened, so that the squeezed blood can have a greater instantaneous pressure. Both the electromagnetism technology and the magnetic pole conversion technology adopt existing technologies.

[0032] Furthermore, a circle of glue is provided on the edge of one side of the surface of the heart rate sensor 3 in contact with the skin; In specific implementation, the heart rate sensor 3 can be better attached to the heart position of the chest through the setting of glue.
