Above-mentioned explanation only is the general introduction partly of technical solutions of the utility model feature, for making the professional and technical personnel can clearer understanding technological means of the present invention, and can be implemented according to the content of description, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.
The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the overall structure view of this utility model pulsation blood, pump for external circulation use.
Fig. 2 is another overall structure view of this utility model pulsation blood, pump for external circulation use.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to its specific embodiment, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.
1. hard shell body 2. blood flow valves
3. advance blood vessel 4. and go out blood vessel
5. sacculus 6. air inlet pipe
7. blood chamber 8. air chambers
See also Fig. 1, shown in Figure 2, this utility model pulsation blood, pump for external circulation use is mainly advanced blood vessel 3, is gone out blood vessel 4 by what the blood storage chamber with a solid shape was connected, and the blood flow valve 2 and the pulse driving device that are arranged in the blood storage chamber constitute.
Blood storage chamber is made up of hard shell body 1, blood flow valve 2 and blood chamber 7.
Pulse driving device drives sacculus 5 by air inlet pipe 6 and big or small telescopic blood to be formed, and it is power sources of blood pump that big or small telescopic blood drives sacculus 5.
Blood storage chamber can be used plastics, lucite or metal material, makes circle, ellipse or square geometry with blowing, injection moulding, cast, compacting or machining.
The blood storage chamber inner face is coated with Polyurethane, silicone rubber, high molecular polymer, polytetrafluoroethylene (PTFE) or heparin material, or with the different thin film polyamine ester films of pad, pellosil, silicone rubber membrane, rubber membrane, polymer membrane or polytetrafluoroethylene (PTFE) film.
Sacculus 5 can be made with Polyurethane, silica gel, rubber, silicone rubber, high molecular polymer or polytetrafluoroethylene (PTFE) material; Its shape can be spherical or oval, and sacculus can be that one, two or three are more, balloon wall can be one deck, two layers or multilayer.
The method of blood storage chamber available membrane, mobile sacculus thin film is separated into air chamber 8 and blood chamber 7 two parts with the blood pump blood storage chamber, and process increase or minimizing air chamber capacity drive blood pump and produce the blood of fighting.
It is 10,20,30,40,60,80,90,100 or the specification of 120ml that extracorporeal circulation pulsatory blood pump can be made capacity.
The inner surface of blood storage chamber must be smooth, and the material that inner surface uses must lack antigenicity, the apyrogeneity reaction; Damage or destruction to blood formed element are little.Its shape will meet principle of hemodynamics, produces eddy current in the blood flow process less as far as possible; The shell of blood storage chamber can be made by any material, also can be any geometry, but principle is to change its volume with the expansion that drives sacculus.The driving effect of blood flow in so in the telescopic process of sacculus, can producing to blood storage chamber.
Drive sacculus dilatancy and stronger nerve are preferably arranged, balloon wall should have toughness and invulnerability preferably, the material of sacculus must have better biocompatibility, and the surface is smooth, and visible component destruction and damage to blood in the process of expanding and dwindling are little.Require it can stand beating and do not damage more than 120,000 times.
Two unidirectional flap valves require resistance that blood flow is produced little, to the visible component of blood destroy and damage little, and the eddy current that produces when making blood flow through this flap valve is little.To surpass 80 times/timesharing the service life of this flap valve and promptly should be able to tolerate beating and do not produce backflowing of valve more than 120,000 in 24 hours.
Basic functional principle and effect
1. utilize exogenous pneumatic or surge to the driving sacculus generation effect in this extracorporeal circulation pulsatory blood pump, make that this sacculus puts out blood volume as required what produce the change in volume that varies in size.
2. because the size of blood storage chamber is fixed, the variation of drive ball capsule volume size will make and produce corresponding pressure in the blood storage chamber and change, pressure be negative pressure or sacculus hour, the near-end flap valve is open, the far-end flap valve is closed, and blood of human body flows to blood storage chamber and storage by pipeline and through this near-end flap valve; When exogenous gas or liquid, when filling drove sacculus, this sacculus expanded outwardly, and the blood storage chamber internal pressure is risen, and this moment, the near-end flap valve was closed, and the far-end flap valve is open, and the blood storage chamber inner blood is through the outflow of far-end flap valve and be back to human body.So come and go repeatedly, make the blood flow one-in-and-one-out form pulsate flow.
3. so pulsatile flow meets Human Physiology, so advection or the non-pulsatile perfusion that uses has more superiority at present, extracorporeal circulation is minimized to the negative effect that human body produces.
4. this extracorporeal circulation pulsatory blood pump has simple to operately, saves time and good serviceability.
5. as needing long-time assist circulation, more non-pulsatile perfusion has more superiority.
The above, it only is preferred embodiment of the present utility model, be not that this utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
