Process for the preparation of sodium hyaluronate gel. |
| abstract |
The present invention relates to a process for the preparation of sodium hyaluronate in which a central control unit is used to: regulate the rotational speed of a motor, thereby controlling the particle size of the pasty gel; controlling the angle of rotation of a valve, so as to control the dialysis time of the first dialysate; receive real-time detection data from a pH value detector and an osmotic pressure detection device; controlling and receiving data from a first bubble detection device to adjust the pumping speed of a vacuum pump; receive data from a second bubble detection device, to adjust the rotational speed of a centrifugal machine; and be connected to a bacteria detection sensor; By the way, make adjustment according to the data and parameters actually detected during the preparation, which makes the process of preparing sodium hyaluronate gel efficient. In addition, the strength of the released sodium hyaluronate gel is calculated based on the strength of the second bubble. If said calculated strength of the sodium hyaluronate gel does not conform to the target strength, adjustments can be made in real time, so as to modify the strength of the sodium hyaluronate gel released. |
