The utility model discloses a temperature control reaction kettle device for a laser velocity field instrument in the technical field of temperature control of reaction kettles. The annular heating rod is arranged in the reaction kettle and is used for heating fluid in the reaction kettle; the semiconductor chilling plate is used for dissipating heat of the reaction kettle and comprises a refrigeration surface and a heat dissipation surface; the water-cooling heat dissipation system comprises a water-cooling plate attached to the heat dissipation face and a cooling liquid circulating pipeline for refrigerating the water-cooling plate. Through cooperation of the annular heating rod, the semiconductor chilling plate and the cooling liquid circulating pipeline, accurate temperature control of fluid in the reaction kettle is achieved, and the reaction kettle is suitable for a laser velocity field instrument.

The application discloses a ventricular support drainage device, which comprises a drainage tube, a self-expanding support bracket, a delivery tube and a support strip. The self-expanding support bracket is arranged outside the drainage tube, and the support bracket in an expanded state is used for supporting the ventricular wall. A small protrusion is arranged inside the support bracket, and the small protrusion is in close contact with the drainage tube in a compressed state. The delivery tube is sleeved outside the drainage tube and the support bracket, and is used for maintaining the drainage tube and the support bracket in the compressed state. The support strip is arranged inside the drainage tube in the compressed state, and is used for supporting the whole structure during delivery. The support strip is used for delivering the drainage tube and the support bracket compressed in the delivery tube to a drainage position under the support of the support strip, and maintaining the position of the drainage tube unchanged when the delivery tube is withdrawn. The support strip is blocked at the first end of the drainage tube. The arrangement guarantees that the drainage device is effectively delivered, and the support bracket plays a supporting role and the drainage tube plays a drainage role after being delivered.
