Description
Technical field
This utility model belongs to medical instruments field, especially a kind of heat exchanger for perfusion apparatus of cardiac arrest liquid.
Background technology
According to medical device industry standard, perfusion apparatus of cardiac arrest liquid is divided into A and Type B, and the water at low temperature that A type uses heat exchange water tank to export is as heat exchange medium, and Type B uses mixture of ice and water as heat exchange medium.A type exports blood heat and stablizes, and be easy to control, but the heat exchange water tank requiring operating room to configure has the ability exporting two-way different temperatures heat exchange water, is generally used for the hands art of low hypothermia perfusion; Type B heat exchanger configuration is comparatively simple, easy to use, and without the need to special equipment, but export the impact that blood heat is subject to mixture of ice and water variations in temperature, fluctuation is comparatively large, wayward, for conventional cardiac surgery operation.Current cardiac muscle stops jumping perfusion device structure only can adopt wherein a kind of heat exchange method, and manufacturer needs the product simultaneously producing this two type usually.
Summary of the invention
In order to solve the problem, this utility model provides a kind of dual-purpose heat exchanger that can meet needed for A, B two profiles state.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of dual-purpose heat exchanger for perfusion apparatus of cardiac arrest liquid of this utility model, comprise end cap (9), threaded collar (2) and shell (4), described end cap (9) arranged outside has blood inlet (1) and blood outlet nozzle (11), inner side is provided with the dividing plate of band groove, silicone rubber seal divider (10) is embedded with in groove, described threaded collar (2) makes U-shaped thin-walled heat-exchange tube (6) be fixed in ring by polyurethane shutoff glue (8), it is bonding with end cap (9) that threaded collar (2) cuts glue end, threaded collar (2) and shell (4) screw and are connected and seal with sealing ring (7), outer casing bottom establishes water inlet tap (5), open section side is provided with faucet (3), be the gloomy interface of the standard Chinese.
This utility model has the function of A, B two kinds of perfusion apparatus of cardiac arrest liquids simultaneously, flexibly and easily, can adapt to the needs of different operating room condition, simplify the process of enterprise's organization of production simultaneously.

Detailed description of the invention
The technological means realized to make this utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth this utility model further.
Embodiment
As shown in Figure 1, a kind of dual-purpose heat exchanger for perfusion apparatus of cardiac arrest liquid of this utility model, comprise end cap (9), threaded collar (2) and shell (4), described end cap (9) arranged outside has blood inlet (1) and blood outlet nozzle (11), inner side is provided with the dividing plate of band groove, silicone rubber seal divider (10) is embedded with in groove, described threaded collar (2) makes U-shaped thin-walled heat-exchange tube (6) be fixed in ring by polyurethane shutoff glue (8), it is bonding with end cap (9) that threaded collar (2) cuts glue end, threaded collar (2) and shell (4) screw and are connected and seal with sealing ring (7), outer casing bottom establishes water inlet tap (5), open section side is provided with faucet (3), be the gloomy interface of the standard Chinese.
Operation principle: perfusion apparatus of cardiac arrest liquid is used for cryocrystal being stoped jumping liquid or blood cardioplegia injection patient coronary artery, makes cardiac arrest, thus creates conditions to cardiac operation under direct vision.Heat exchanger is its core component, is reduced to operation demand for stoping jumping liquid temp.When a complete set of filling apparatus production and assembly, heat exchanger blood inlet is connected with the pump line port of export, and blood outlet nozzle is connected with intrusion pipe.
A type state: crystal stops jumping liquid or blood cardioplegia injects heat exchanger by blood inlet, then be diverted in each heat-exchange tube, converge to blood outlet nozzle after circulating one week and flow out.Heat-exchange tube water is cooled to 4 DEG C by water tank, is filled with housing by outer casing bottom water inlet tap, flows through, then flowed out by faucet outside heat-exchange tube.Heat exchange is there is in what temperature was higher stop jumping liquid and the lower cold water of temperature on thin-walled heat-exchange tube surface.
Type B state: screw thread between product threaded collar and housing is turned on, removes shell, heat-exchange tube is all inserted in mixture of ice and water.Stop jumping liquid endless form identical with A type, during perfusion, need operator often to stir ice bucket, to make homogeneous temperature in bucket, obtain good alternating temperature effect.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
