Intravenous injection model used for nursing teaching

Abstract

The invention discloses an intravenous injection model used for nursing teaching. The intravenous injection model comprises a telescopic support rack, a groove is formed in the upper surface of the telescopic support rack, a shoulder bent rod is rotatably connected in the groove, an upper arm support rod is fixedly connected to one end of the shoulder bent rod, a turntable is fixedly connected toone end of the upper arm support rod, bionic muscle is fixedly connected to the outer surfaces of the upper arm support rod and a lower arm support rod, bionic fiber blood vessels are laid in the bionic muscle, fiber catheters are fixedly connected to the upper ends of the bionic fiber blood vessels, and laser spotlights are fixedly connected to the surfaces of the fiber catheters. For the intravenous injection model used for nursing teaching, through the matched arrangement of the bionic fiber blood vessels, the fiber catheters and the laser spotlights, during the use process of teaching, light sources of the laser spotlights enter the bionic fiber blood vessels along the fiber catheters, so that the effect of displaying the bionic fiber blood vessels with high luminance is achieved, therefore, a nurse can clearly check the own mistake points after each time of practice, and thus the pertinence of teaching practice is improved.

Description

technical field [0001] The invention relates to the technical field of medical teaching equipment, in particular to an intravenous injection model for nursing teaching. Background technique [0002] Intravenous injection is to directly inject liquid substances such as blood, medicinal liquid, and nutrient solution into the vein. It is a medical method. Superficial veins in back, ankle, etc. [0003] The reasons for the failure of intravenous injection are as follows: 1. After the needle enters the subcutaneous area, it fails to puncture repeatedly along the vein, scratches the blood vessel wall, and causes the injected drug to overflow, causing local swelling and pain; 2. It is not detected before the puncture The vein is deep and shallow, and the needle penetrates too deep and penetrates the contralateral vessel wall; 3. Blood return can be seen after the puncture, but after the tourniquet is loosened, there is no return of blood. If the drug is injected, the local swellin...
