Abstract
The utility model discloses an intravascular mini blood supply pump which comprises a casing, a rotor impeller, a stator coil, a permanent magnet and two bearings, wherein the stator coil is stuck onto the inner surface of the casing with the use of epoxy resin, the permanent magnet is stuck to the outer surface of the middle part of the rotor impeller with the use of epoxy resin, the spiral blades of the rotor impeller are arranged inside the inner bore of the rotor impeller, the rotor impeller that is bonded with the permanent magnet is spatially mounted inside the inner bore of the stator coil, the outer circles of the two bearings are arranged inside the holes at the two ends of the casing by means of interference fit respectively, and the inner bores of the two bearings are mounted into the outer circles of the two ends of the rotor impeller by means of interference fit respectively. After the assembly, the blood supply pump is characterized in that the rotor impeller that is bonded with the permanent magnet can rotate inside the casing that is bonded with the stator coil, so that after the blood supply pump is implanted in a blood vessel and the stator coil is connected with a direct current source, the rotor impeller begins to rotate under the action of the electromagnetic field to increase the blood flow, and the auxiliary function of blood supply is achieved.
Description
Technical field
This utility model belongs to the medical apparatus technical field, a kind of specifically can the implant into body blood vessel in the blood vessel built-in miniature of the accessory heart blood supply pump of enriching blood.
Background technology
Clinically, for sudden heart disease, particularly suffer from the patient of myocardial dysfunction, because patient self blood supply ability drop, at this moment being starved of by auxiliary its heart of the machine power in the external world increases amount of blood supply.At present, common heart assistance blood supply facility is the blood cardiopulmonary bypass pump, and its shortcoming is: equipment volume is big, and pipeline is long, patient's limitation of activity, and infected easily and formation thrombosis needs the special messenger and operates control, and can not life-time service.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art, provide a kind of volume little, directly in the implant into body blood vessel, the pump with the mobile blood vessel built-in miniature of human body is enriched blood.
For achieving the above object, the technical solution adopted in the utility model is: a kind of blood vessel built-in miniature pump of enriching blood, by shell, impeller of rotor, stator coil, permanent magnet, bearing constitutes, its structure is: stator coil is by the inner surface place of adhering with epoxy resin at the shell middle part, permanent magnet is by the outer surface of adhering with epoxy resin at the impeller of rotor middle part, the spiral vane of impeller of rotor is arranged in the endoporus of impeller of rotor, the impeller of rotor that is bonded with permanent magnet is installed in the endoporus of stator coil with a gap, the cylindrical of 2 bearings is respectively in the hole at the shell two ends of packing into of interference fit, simultaneously the endoporus of 2 bearings cylindrical place at the impeller of rotor two ends of packing into of interference fit respectively.The pump of enriching blood that assembling is finished is characterized in that: the impeller of rotor that is bonded with permanent magnet can rotate in being bonded with the shell of stator coil, after connecting dc source in the blood vessel that the pump of enriching blood is packed into and with stator coil, begin to rotate that blood flow is increased at the effect lower rotor part impeller of electromagnetic force, play the effect of auxiliary blood supply.
The beneficial effects of the utility model are: because the spiral vane of impeller of rotor is arranged in the hole of impeller of rotor, permanent magnet is by the outer surface of adhering with epoxy resin at the impeller of rotor middle part, make close together between permanent magnet and the stator coil like this, thereby increased the rotating torque of impeller of rotor, reduced energy loss.The blood vessel built-in miniature is enriched blood behind the pump implant into body, and the pump of enriching blood can arbitrarily move along with the patient, and the pump of enriching blood in bed is not subjected to the restriction of human body position.
