Abstract
The utility model relates to a blood heat exchanger which is matched with a blood oxygenator used in surgical operation. The blood heat exchanger is provided with a bundle of heat exchanging capillary tubes which are in multi-layer intersection-braid and are assembled in a housing. Sealed bodies are arranged between both end sides of the bundle of heat changing capillary tubes and the housing. One end of the housing is assembled with an end cover, the other end is assembled with a closing cover which is assembled with a water inlet pipe and a water outlet pipe, and the inner side of the closing cover is assembled with a water proof strip. The lower side of the housing is assembled with a blood inlet pipe, and the upper side is assembled with a blood outlet pipe and a connector. The blood heat exchanger has the advantage of high heat exchanging efficiency, and can effectively overcome the temperature difference of blood cells. The required blood priming volume is small, and a blood heat exchanger matched with an adult oxygenator only requires the blood priming volume of 50 ml.
Description
This utility model guarantees to keep the heat-exchanger rig that blood heat meets the demands during relating to a kind of surgical operation, refers in particular to and the matching used blood heat-exchanger rig of blood oxygenator.
In known prior art, no matter be that bubble oxygenator or membrane oxygenator all must adopt the supporting use of heat-exchanger rig, the technical pattern of this blood heat-exchanger rig has telescopic, shell and tube, coil pipe type or bellows-type, but there is certain shortcoming and defect part in they aspect raising heat exchange efficiency or the reduction blood priming amount separately.
The purpose of this utility model provides a kind of enough heat exchange areas and heat exchange efficiency of both having guaranteed, can reduce the blood heat-exchanger rig of blood priming amount simultaneously again to greatest extent.
Technical application scheme of the present utility model is to abandon the routine techniques that existing blood heat exchanger adopts, but sophistication constitutes the blood heat exchanger with the heat exchange capillary tube.It is assembling heat exchange bundle of capillary tubes in housing, between the two ends hand hay cutter of this heat exchange bundle of capillary tubes and the housing seal is arranged, the one end assembling Yi Feng Cover of housing, its another Zhuan Pei Tou Cover Tou Cover inboard is equipped with on the water proof bar Tou Cover and is fitted into water pipe and outlet pipe, the downside assembling blood inlet tube of housing, upside assembling blood outlet and connector.
In order to improve heat exchange efficiency, select for use heat exchange internal diameter capillaceous less than 1 millimeter, and be heat exchange bundle of capillary tubes interlacing the heat exchange capillary tube axially parallel of each layer of multiple structure, and the heat exchange bundle of capillary tubes of one deck and another layer axially intersects an angle.
For the blood priming amount that reduces this blood heat exchanger with select for use suitable heat exchange area to assemble a Accounting position core at the center of heat exchange bundle of capillary tubes multiple structure.
Flow more rationally in order to make blood enter heat exchange bundle of capillary tubes outer wall gap distribution, have blood distributing slot and blood inlet tube to match in the downside inwall design of housing, the design of housing upper inside walls has blood afflux groove and blood outlet to match.
For fear of leakage phenomenon, design has seal groove between housing and seal, and also designing between Accounting position core and the seal has seal groove.
The blood inlet tube of blood autoblood heat exchanger downside enters in the blood heat exchanger shell, mobile water carries out heat exchange in outer wall gap by the heat exchange bundle of capillary tubes and the heat exchange capillary tube beam tube, and the blood that becomes suitable temperature through heat exchange enters blood oxygenator or other devices from the blood outlet of blood heat exchanger upside.The connector of blood heat exchanger upside is used for being connected with oxygenator.The outlet pipe of current on a Cover after the blood heat exchange that water inlet pipe on the current autoblood heat exchanger head capsule enters in the pipe of the intravital heat exchange bundle of capillary tubes of shell and tube wall is outer flows out the blood heat exchanger, and current come and go away round trip from bottom to top in the heat exchange bundle of capillary tubes.
The advantage of this blood heat exchanger is the heat exchange efficiency height, because heat exchanger tube adopts the heat exchange bundle of capillary tubes of multilamellar interlacing, makes the mobile turbulent condition that remains on of blood, has overcome the blood cell temperature difference effectively.Simultaneously because heat transfer zone is intensive bundle of capillary tubes, reduced the required preliminary filling volume of unit heat exchange area widely, it is 140 milliliters that the required preliminary filling volume of the design changes the ground area for every square metre, in fact with the capillary tube area of a matching used blood heat exchanger of oxygenator less than 0.4 square metre, the desired blood priming volume only is about 50 milliliters.
Accompanying drawing is the new example structure sketch map of this practicality:
Drawing explanation: 1-blood inlet tube, 2-housing, 3-Accounting position core, 4-Feng Cover, 5-heat exchange bundle of capillary tubes, 6-blood outlet, the 7-connector, 8-seal, 9-Tou Cover, 10-water inlet pipe, 11-water proof bar, the 12-outlet pipe, 13-seal groove, 14-seal groove, 15-blood distributing slot, 16-blood afflux groove.
Embodiment:
Now in conjunction with the accompanying drawings structure of the present utility model is further elaborated, assembling heat exchange bundle of capillary tubes 5 in housing 2 as shown in the figure, heat exchange bundle of capillary tubes 5 is the multiple structure of interlacing, between its both end sides and the housing 2 seal 8 is arranged, at the center of heat exchange bundle of capillary tubes 5 assembling Accounting position core 3, design has seal groove 14 between housing 2 and seal 8, design has seal groove 13 between Accounting position core 3 and seal 8, the one end assembling Feng Cover 4 of housing 2, the inboard of the other end Zhuan Pei Tou Cover 9 Tou Cover 9 of housing 2 is equipped with on the water proof bar 11 Tou Cover 9 and is fitted into water pipe 10 and outlet pipe 12, the downside assembling blood inlet tube 1 of housing 2, the downside inwall design of housing 2 has blood distributing slot and blood inlet tube 1 to match, the upside assembling blood outlet 6 and the connector 7 of housing 2, the upper inside walls design of housing 2 has blood afflux groove and blood outlet 6 to match.
