Syringe Body Negative Pressure Tightness Tester-Technical Literature

Syringe Body Negative Pressure Tightness Tester-Technical Literature Syringe As early as the 15th century, the Italian Cartinel proposed the principle of the syringe
.

It was not until 1657 that the Chinese Boyle and Wren conducted a human experiment
.

Pravoz of France is generally considered to be the inventor of the syringe
.

The syringe he supervised in 1853 was made of silver, had a capacity of only 1 ml, and had a threaded piston rod
.

 The Englishman Ferguson used a glass syringe
.

The glass has good transparency, and you can see the situation of injected drugs
.

Thereafter there are glass tubes made of metal and syringes
.

The syringes currently used are made of plastic, which can be thrown away after one use, greatly reducing the risk of infection during injection
.

 Now the syringe is a common medical device in the hospital.
It is used to extract the liquid medicine and then inject the liquid medicine into the patient's body.
It is not difficult to see that the tightness of the syringe directly affects the efficacy of the internal medicine liquid.
Jinan Sanquan Zhongshi The syringe negative pressure tightness tester produced by Experimental Instruments is a testing instrument that can detect various syringes
