Detailed Description

The embodiment of the utility model discloses a blood vessel double-loop puncture model under ultrasonic guidance, which comprises the following components as shown in figures 1-3:

a blood vessel access 5 and a blood vessel loop 7 are fixedly installed on the side wall of the water storage tank 3, a silica gel module 6 is arranged at the junction of the blood vessel access 5 and the blood vessel loop 7, the blood vessel access 5 and the blood vessel loop 7 are both arranged inside the silica gel module 6, and a speed regulating switch 9 is arranged on the blood vessel loop 7;

circulating pump 4, circulating pump 4 fixed mounting are in the inside of tank 3, and circulating pump 4's lateral wall fixedly connected with

power cord

2, and 3 outside extensions and fixedly connected with power plug 1 of tank are passed to the tip of power cord 2, and circulating pump 4's output and blood vessel are gone into 5 fixed links to each other.

According to shown in attached figures 1 and 2, the top movable joint of the water storage tank 3 is provided with a top cover 8, the top cover 8 is arranged to protect the top of the water storage tank 3, and foreign matters are prevented from entering the water storage tank 3 when the device is used.

According to shown in figures 1 and 2, the bottom fixedly connected with rubber buffer of top cap 8, the rubber buffer activity joint of top cap 8 is at the open-top of tank 3, and the rubber buffer that sets up can guarantee that the open-top block of top cap 8 and tank 3 is effectual, is difficult for the pine to the top cap 8 of setting is at the open-top of tank 3 easy dismounting.
