Technical Field
The invention relates to the technical field of medical instruments, in particular to an automatic microbubble forming and injecting device for a foaming test.
Background
The TCD foaming test is a saline water excitation test method by using transcranial Doppler ultrasound, and is an important examination means for diagnosing right-to-left shunting of the heart.
The current TCD foaming test operation flow is as follows: 1) 3 tubes of 10ml of pre-saline, 2 tubes of 9ml of saline and one tube of 1ml of air were prepared. Connecting a saline injector with an air injector by using a three-way switch, connecting the other end of the saline injector with a No. 8 infusion needle, and puncturing the elbow vein of a patient; 2) a small amount of blood was drawn into 1 needle tube through the three-way switch (the blood's function was to increase the time for air bubbles to float in the blood to ensure detectability). Before injection, one of the operators pushed 2 syringes back and forth over 10 more times to shake the saline sufficiently to make the blood, saline and air into a microbubble suspension, i.e., to activate the saline. 3) The prepared activated saline was injected intravenously, and another operator operated the TCD to observe the presence or absence of microemboli within 10 s.
