AI Technical Summary

Technical Problem

The existing mouse model has only one venous blood vessel, which affects actual teaching and is difficult to determine whether the syringe is inserted into the venous blood vessel.

Method used

A mouse tail vein injection model was designed, which included 3 grooves and 3 water inlet pipes. The blood vessels in the mouse tail were simulated through the vascular simulation tube, and the needle insertion was detected using a water flow alarm, and the needle sealing and injection process were monitored through the sealing sheet and the guide sheet.

Benefits of technology

It realizes the simulation of multivenous blood vessels, which is convenient for teaching, and can monitor the needle insertion and injection process in real time, improving the accuracy and visualization of teaching.

Abstract

The present invention discloses a mouse tail vein injection model, comprising: a mouse model, a cavity is formed in the abdomen of the mouse model, and an installation chamber is formed above the rear side of the cavity; a water flow alarm, the water flow alarm is arranged at the front end of the mouse model's tail, a water outlet pipe is connected to the front end of the water flow alarm, a water inlet pipe is connected to the rear end of the water flow alarm, and a sealing piece is arranged at the connection between the water inlet pipe and the water flow alarm, the rear end of the water inlet pipe is connected with a connector; a groove, the groove is formed on the outer side of the mouse model's tail, and a blood vessel simulation tube is arranged inside the groove. This mouse tail vein injection model is convenient for simulating the blood vessels on the left, right, up and down of the mouse tail. When the syringe needle is inserted into the blood vessel simulation tube, an alarm is triggered through the detection of the water flow alarm to indicate the completion of the injection. The water flowing into the cavity can be discharged by opening the drain hole, which is convenient to use.
