In the use process, when the baffle 12 is in a normal closing state, the electromagnet 13 is electrified to adsorb the baffle 12, and at the moment, the baffle 12 is difficult to be pulled open directly. The identification card is required to be in contact with the sensing module 5, after the sensing module 5 recognizes correct information, a signal is sent to the control module 4, the electromagnet 12 is controlled to be powered off for a certain time, for example, 5-10s, the adsorption of the baffle 12 is stopped, the baffle 12 is still attached to the shell 1 at the moment, but the baffle 12 can be pulled open easily at the moment, and after the time passes, the control module 4 controls the electromagnet 13 to be powered on. The specific size and magnetic force of the electromagnet 13 are set according to the actual requirement in combination with the overall size of the infusion control mechanism, and are not particularly limited herein.

In the present utility model, the fixture 2 includes a power module and two clamping blocks 21, the two clamping blocks 21 are parallel and oppositely arranged, and the power module drives the two clamping blocks 21 to approach or separate from each other in the accommodating groove 11. For the articulated clamping structure, the clamping modes of two clamping blocks 21 which are parallel and oppositely arranged can lead the surface stress of the clamping type infusion tube to be more uniform, so as to be convenient for quantitatively adjusting the infusion drip speed according to the moving stroke of the clamping blocks 21.

The power module is a rotary driving piece 22, which is fixedly arranged in the shell 1, and the clamp 2 is specifically electrically connected with the control module 4 through the rotary driving piece 22.

In the utility model, the clamp 2 is not only used for clamping the infusion tube after the infusion is completed to play a role of stopping, but also can play a role of replacing a flow rate regulator to regulate the flow rate. An adjusting button 6 is further arranged on the shell 1 and used for adjusting the clamping degree of the clamp 2 so as to adjust the infusion dropping speed. The adjusting button 6 specifically includes an acceleration button and a deceleration button, which are both electrically connected to the control module 4. It is preset that when the rotation driving member 22 is rotated forward, the two clamping blocks 21 are moved close to each other, and when the rotation driving member 22 is rotated backward, the two clamping blocks 21 are moved away from each other. The acceleration button in the adjustment button 6 is a button for controlling the rotation of the rotation driving member 22 to rotate reversely, and the deceleration button is a button for controlling the rotation driving member 22 to rotate forwardly. The preset one-time pressing of the acceleration button, the fixed reverse rotation of the rotary driving member 22 is designated and stopped, the preset one-time pressing of the deceleration button, the fixed forward rotation of the rotary driving member is designated and stopped, so as to perform quantitative adjustment. In the actual infusion process, the patient may want to adjust the infusion speed by himself because the standard infusion speed is too slow, and in one mode of the present utility model, the patient may directly press the corresponding adjusting button 6. In other embodiments of the present utility model, the adjustment button 6 is activated for a predetermined time, for example, 5-10s, after the identification card contacts the sensing module 5, and during this activation time, the adjustment button 6 is effectively pressed to perform adjustment, that is, when the sensing module 5 senses the identification card information, a signal is sent to the control module 5, and at this time, the adjustment button 6 is pressed, the control module 5 correspondingly controls the rotation driving member 22 to work, and after the activation time elapses, the control module 5 does not make a reaction for controlling the rotation driving member 22 to work when the adjustment button 6 is pressed. So as to avoid the patient from automatically regulating the infusion speed, ensure that the liquid medicine can be infused according to the set standard of medical staff, and be suitable for the treatment of patients with the infusion speed needing to be strictly controlled.
