Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the small animal model described in the present invention rotates the continuous intravenous infusion device, and the electric furnace wire 3 is properly stretched to 55-60 cm to make it soft and have a certain strength, and protect the medical silicone tube 6 passing through its center. To avoid being bitten by experimental small animals, remove the tip of the disposable syringe needle 5 and grind it flat, insert one end of the 1.0mm silicone tube 6 to fix it, carve a groove on the same horizontal line as the 4 plastic support wings of the needle base, and place the electric furnace wire 3 One end is fixed in the groove, and the far end of the needle cap 4 is cut off a little and inserted into the injection needle 5 connected with the silicone tube 6 and the electric furnace wire, so as to prevent the silicone tube 6 from being pierce...

Abstract

The invention relates to a medical experimental tool, in particular to a rotary continuous venous transfusing device for a small animal model, which is suitable for performing long-term durable and effective venous transfusion on a small medical experimental animal without influencing free movement of the small experimental animal in the medical experimental process. The device is formed by connecting a disposable transfusing apparatus, a heparin cap, a disposable injector needle tube and a disposable injector needle head in series in sequence, and is connected with a silicone tube; one end of a spring protecting sleeve is fixedly connected to the needle head; the needle cap is sleeved into the needle head which is connected with the silicone tube and the spring protecting sleeve; the center of a plastic fixing plate is provided with a recess; the center of the recess is provided with a hole; a hollow rivet is fixedly connected with the other end of the spring protecting sleeve by passing through the central hole of the plastic fixing plate; a triangular gap is cut on the side wall of the needle tube; and standby needle holes are formed on the periphery of the plastic fixing plate.

Description

technical field [0001] The invention relates to a medical experiment appliance, specifically a rotating continuous intravenous infusion device for small animal models, which is suitable for performing long-term continuous and effective intravenous infusion on small animals in medical experiments without affecting the free activities of experimental small animals in the course of medical experiments . Background technique [0002] Small bowel transplantation is the most effective method for the treatment of end-stage intestinal failure, but the occurrence of rejection is still the main reason for transplantation failure. Due to the high cost, difficult operation and low survival rate of the previous medical methods, the research of small bowel transplantation more difficult. [0003] The inventors have proved through medical experiments that the combined application of the rotating continuous intravenous infusion device and the heterotopic small intestine transplantation mod...
