[0017] Beneficial effects:

[0018] 1. The device is provided with a storage mechanism. When the catheter is not in use, the top cover is rotated to bend the infusion connector outside the catheter and store it inside the outer shell, thereby properly protecting the infusion connector and reducing the potential damage to the catheter caused by external extrusion. At the same time, the extrusion plate can be used to press down the exposed part of the catheter to cut off the connection between the catheter and the outside. The downward extrusion plate can provide a physical barrier to prevent microorganisms in the air from entering the catheter system, thereby reducing the risk of infection.

[0019] 2. The device is provided with a closing mechanism. When the top cover rotates, the infusion connector of the catheter is wrapped between the upper cover plate and the lower cover plate, thereby physically isolating the infusion connector of the catheter from the outside. Through physical isolation, the infusion connector is completely enclosed in a clean and sterile environment, effectively preventing bacteria or dust in the air from contacting the catheter port, reducing the risk of infection. At the same time, the clamping effect of the upper cover plate and the lower cover plate can firmly fix the infusion connector of the catheter, reducing the possibility of displacement or partial removal of the catheter due to accidental pulling or other external forces.

[0020] 3. The device is provided with a collecting mechanism. After the upper cover and the lower cover wrap the infusion connector of the catheter, the residual liquid medicine in the infusion connector of the catheter drips into the lower cover. Finally, the lower cover rotates to put the collected liquid medicine into the collecting shell. The design of the collecting shell can effectively capture and store the liquid medicine dripping from the infusion connector of the catheter, so as to prevent the dripping liquid medicine from contacting the external environment or the patient's skin and reduce the risk of accidental exposure.

[0021] 4. The device is provided with a fixing mechanism and a limiting mechanism, and utilizes two movable plates to limit the exposed part of the infusion catheter to the inside of the outer shell, so as to avoid movement between the exposed part of the infusion catheter and the outer shell. When using the catheter, the round end of the Velcro is in contact with the bristle end of the Velcro, so that the outer shell and the exposed part of the infusion catheter inside it are fixed to the surface of the patient's body. Under the protection of the outer shell, the exposed part of the infusion catheter can be prevented from rubbing against the patient's clothes during use and causing damage.

[0022] 5. This device is provided with an adjustment mechanism. When the outer shell is fixed on the patient's arm, the main airbag and the auxiliary airbag are used to fill the gap between the patient's arm and the outer shell. The main airbag and the auxiliary airbag can be inflated and adjusted according to the specific shape of the patient's arm to ensure that the outer shell fits tightly without compressing the skin, thereby improving the wearing comfort. At the same time, the airbag can provide a more uniform pressure distribution, avoid the impact of excessive local pressure on the blood vessels, and help maintain the stability of the catheter position.

A second hinge seat 206 is rotatably connected to the outer side of the outer shell 201, and the guide rod 207 slides through the second hinge seat 206. A first spring 208 is sleeved on the outside of the guide rod 207, and the first spring 208 is located on the outside of the guide rod 207 between the first hinge seat 205 and the second hinge seat 206.

[0042] During specific operation, when the infusion connector of the catheter 10 is not in use, the top cover 202 can be rotated, and the top cover 202 drives the end of the catheter 10 to bend, so that the infusion connector of the catheter 10 is bent and stored inside the outer shell 201, and the infusion connector of the catheter 10 is properly protected, reducing the potential damage to the catheter 10 caused by external squeezing. At the same time, the top cover 202 drives the squeezing plate 209 to press down on the outside of the outer part of the catheter 10, and the squeezing plate 209 squeezes the catheter 10 so that the catheter 10 is blocked, cutting off the connection between the catheter 10 and the outside, and the pressed squeezing plate 209 can provide a physical barrier to prevent microorganisms in the air from entering the catheter 10, thereby reducing the risk of infection.

[0043] When the infusion connector of the catheter 10 is used, after the top cover 202 is opened, the first hinge seat 205 is pushed away from the second hinge seat 206 by the elastic force of the first spring 208, so that the rotating plate 203 rotates ninety degrees along the arc groove 204, and the rotating rotating plate 203 pushes the infusion connector of the catheter 10 out of the outer shell 201, so that the infusion connector of the catheter 10 continues to be used.

The flipped lower cover plate 303 and the upper cover plate 302 on the side of the top cover 202 wrap the infusion connector of the catheter 10, thereby physically isolating the infusion connector of the catheter 10 from the outside. Through physical isolation, the infusion connector of the catheter 10 is completely enclosed in a clean and sterile environment, effectively preventing bacteria or dust in the air from contacting the port of the catheter 10, reducing the risk of infection.

[0047] When the top cover 202 is opened, the second spring 309 pushes the rack 307 upward to drive the gear 306 to rotate in the opposite direction. The gear 306 that rotates in the opposite direction drives the lower cover 303 to rotate 180 degrees through the rotating shaft 305, so that the dripping medicine in the lower cover 303 falls into the collecting mechanism 40, thereby preventing the medicine from leaking out and affecting the patient.

The main airbag 601 and the auxiliary airbag 602 are used to fill the gap between the patient's arm and the outer shell 201 through the adjustment mechanism 60. The main airbag 601 and the auxiliary airbag 602 can be inflated and adjusted according to the specific shape of the patient's arm to ensure that the outer shell 201 fits tightly without The skin is compressed, thereby improving the wearing comfort. When the infusion connector of the catheter 10 is not in use, the infusion connector of the catheter 10 is bent and stored in the storage mechanism 20, so that the infusion connector of the catheter 10 is properly protected, reducing the potential damage to the infusion connector of the catheter 10 caused by external compression. At the same time, the storage mechanism 20 drives the sealing mechanism 30 to isolate the infusion connector of the catheter 10 from the outside. After the infusion connector of the catheter 10 is isolated, the collection mechanism 40 is used to collect the residual liquid medicine in the infusion connector of the catheter 10 to prevent the liquid medicine from contacting the external environment or the patient's skin.
