[0038] like Figure 3 As shown, observation windows are provided on both the front and rear sides of the first connecting plate 31 .

[0039] like Figure 4 As shown, the cover plate 51 is made of transparent glass.

[0040] like Figure 5 and Figure 6 As shown, the limiting mechanism includes a first guide rail 55, and the two first guide rails 55 are respectively fixed to the middle parts of the front and rear sides of the inner wall of the first connecting plate 31, and a limiting cover 56 is slidably connected between the front and rear first guide rails 55. A spring 551 is fixed between the limiting cover 56 and the first guide rail 55. A support frame 57 is fixed to the middle part of the left side of the inner wall of the hinged cover plate 4, and a connecting rod 58 is rotatably connected to the top of the support frame 57. The lower left part of the cover plate 51 is movably connected to the left end of the connecting rod 58, and the right end of the connecting rod 58 is squeezed and fitted with the left side of the limiting cover 56.

[0041] like Figure 7-Figure 9As shown, the wiping mechanism includes a first connecting rod 61, and the two first connecting rods 61 are respectively slidably connected to the front and rear sides of the mounting plate 3, and the sweat-absorbing pad 62 is clamped on the side where the two first connecting rods 61 are close to each other, and the positive magnetic strip 63 is fixedly connected to the side where the two first connecting rods 61 are close to each other, and the guide blocks 65 symmetrically distributed on the front and rear sides of the first connecting plate 31 are fixedly connected, and the middle part of the guide block 65 is slidably connected to a connecting frame 64, and a positive magnet 641 is fixedly connected to the bottom of the connecting frame 64, and a negative magnet 642 is fixedly connected to the bottom of the positive magnet 641, and the positive magnet 641 and the negative magnet 642 are both magnetically matched with the adjacent positive magnetic strip 63, and a first magnetic plate 643 is fixedly connected to the top of the connecting frame 64, and the second magnetic plates 66 symmetrically distributed on the front and rear sides of the cover plate 51 are fixedly connected, and the first magnetic plate 643 is magnetically matched with the adjacent second magnetic plate 66.

[0042] like Figure 8 As shown, the sweat-absorbing pad 62 is made of bamboo fiber.

[0043] When the patient needs to protect the PICC catheter on the arm, the arm can be passed through the shell 1 and the mounting plate 3, and the PICC catheter can be located just below the cover plate 51, and then the shell 1 and other components can be fixed on the arm through the fixing mechanism. When the patient's PICC catheter needs to be connected to the external infusion tube and infusion is performed, the hinged cover plate 4, the cover plate 51 and the second magnetic plate 66 and other components can be flipped upward and opened. At this time, since the second magnetic plate 66 is rotated upward, the flipping range of the cover plate 4 is large, so that the second magnetic plate 66 and the first magnetic plate 643 are quickly separated, and the first magnetic plate 643 and the connecting frame 64 are not driven. The components move upward, and then the medical staff can connect the PICC catheter to the external infusion tube and perform infusion, and then flip the hinged cover 4, the cover plate 51 and the second magnetic plate 66 downward and close them. At this time, the second magnetic plate 66, the hinged cover 4 and the cover plate 51 can be limited and fixed by the first magnetic plate 643, and the infusion tube will pass between the upper and lower sealing covers 41 and be limited and fixed to prevent the PICC catheter from accidentally detaching from the external infusion tube. At this time, a relatively closed space will be formed between the shell 1, the connecting soft board 2, the mounting plate 3 and the arm to prevent external bacteria from entering and causing infection.

[0044] However, when the arm is in a relatively closed space, the temperature inside the space will gradually rise due to the gradual dissipation of body temperature. When the sensor 54 detects that the temperature in the space is high, the controller will start the electric push rod 53 and drive the cover plate 51, the filter 52 and the second magnetic plate 66 to move upward, so as to leak the filter 52 and ventilate and dissipate heat to the arm, so as to avoid excessive temperature causing the patient's arm to sweat a lot and cause infection at the intubation site. The presence of the filter 52 can also reduce the entry of external dust and impurities, thereby reducing the risk of infection. The second magnetic plate 66 moves upward and moves the first magnetic plate 643 adsorbed and fixed thereto upward. When it is not moving, the positive magnet 641 is located opposite the positive magnetic strip 63, and the positive magnet 641 and the positive magnetic strip 63 repel each other, thereby causing the two first connecting rods 61 and the sweat-absorbing pad 62 to move away from each other, and the sweat-absorbing pad 62 will not contact the arm. When the first magnetic plate 643 moves upward with the connecting frame 64, the positive magnet 641 and the negative magnet 642, the negative magnet 642 will move upward to face the positive magnetic strip 63, thereby attracting and fixing the adjacent positive magnetic strip 63. At this time, the two positive magnetic strips 63, the first connecting rod 61 and the sweat-absorbing pad 62 will move toward each other, and the two sweat-absorbing pads 62 will move toward each other and contact the patient's arm, thereby wiping and absorbing most of the sweat and other body fluids on the patient's arm to prevent sweat from breeding bacteria and causing infection. Other small amounts of sweat can gradually evaporate during ventilation, and the upward movement of the cover plate 51 will drive the connecting rod 58 to rotate clockwise by a certain angle, and the clockwise rotation of the connecting rod 58 will contact and squeeze the limiting cover 56, so that the limiting cover 56 moves downward and contacts the arm, and the spring 551 is immediately compressed to fix the PICC catheter and the The external infusion tube is blocked and protected to prevent the sweat-absorbing pad 62 from touching the PICC catheter and the external infusion tube when it moves and causing the tube to loosen. When the sensor 54 detects that the temperature has dropped to a normal level, the controller will cause the electric push rod 53 to drive the cover plate 51, the filter screen 52, the second magnetic plate 66 and other components to move downward and reset. The second magnetic plate 66 will drive the first magnetic plate 643, the connecting frame 64 and the positive magnet 641 and other components to move downward and reset. As a result, the two positive magnetic strips 63, the first connecting rod 61 and the sweat-absorbing pad 62 are all moved in the opposite direction and reset through the positive magnet 641. At regular intervals, the mounting plate 3 and other components can be removed from the shell 1 as a whole, and the sweat-absorbing pad 62 can be cleaned and replaced. The downward movement of the cover plate 51 will also cause the connecting rod 58 to rotate counterclockwise and reset, and the limit cover 56 also moves upward and reset under the action of the spring 551.

[0045] Embodiment 2 of the present invention:

[0046] On the basis of Example 1, Fig.10 and Fig.11As shown, the fixing mechanism includes a silicone ring 71, and the two silicone rings 71 are respectively fixed to the ends of the two connecting soft boards 2 that are away from each other. Elastic ropes 72 are fixed to the outside of the two silicone rings 71 on the sides away from each other. A second guide rail 75 is fixed to the front side of the shell 1, and second connecting rods 74 are slidably connected to the left and right sides of the second guide rail 75. Pull ropes 73 that are equidistantly distributed around the circumference are fixed between the second connecting rod 74 and the adjacent elastic ropes 72. A rotating block 76 is rotatably connected to the middle part of the front side of the second guide rail 75, and the rotating block 76 is in contact and cooperates with the second connecting rod 74.

[0047] When the patient wants to put the shell 1 and the mounting plate 3 on the appropriate position of the arm, since the elastic rope 72 is in a stretched state and the ends of the two silicone rings 71 that are away from each other are in an expanded state, the patient's arm can easily pass through the silicone ring 71 without scratching the PICC tube. After adjusting the shell 1 and the mounting plate 3 to a suitable position, the rotating block 76 can be rotated counterclockwise to separate the rotating block 76 from the second connecting rod 74. At this time, the elastic rope 72 and the silicone ring 71 will deform under the action of their own elasticity to restore to a normal state and clamp the arm, thereby not only improving the overall The sealing property prevents external bacteria from entering the intubation site and reduces the probability of infection. It can also fix the shell 1 and other components on the patient's arm to prevent loosening and falling off. The deformation of the elastic rope 72 and the silicone ring 71 will cause the second connecting rods 74 on the left and right sides to move backwards through the pull rope 73. When the patient needs to remove the shell 1 and the mounting plate 3 and other components, the second connecting rods 74 on the left and right sides can also be moved toward each other to reset, and the rotating block 76 can be reversed to limit and fix the second connecting rod 74. At this time, the pull rope 73 is stretched straight, which will cause the elastic rope 72 and the silicone ring 71 to deform and expand, thereby facilitating the patient to pull out his arm.

[0048] like Fig.13 and Fig.14 As shown, a limiting mechanism is also included, which is arranged on the shell 1. The limiting mechanism includes a guide plate 91, which is fixed to the bottom of the shell 1. A locking plate 92 is fixed to the left side of the bottom of the guide plate 91. A second connecting plate 93 is slidably connected to the bottom of the guide plate 91. A latch rod 931 is slidably connected inside the locking plate 92. The latch rod 931 is slidably connected to the second connecting plate 93. A Velcro 94 is fixed to the bottom of the second connecting plate 93.

[0049] When the patient receives an infusion through the PICC tube at night, the second connecting plate 93, the guide plate 91 and the shell 1 can be adhered and fixed to the bed with the help of Velcro 94, and the latch rod 931 can be pulled out and the arm, shell 1, guide plate 91 and locking plate 92 can be rotated until the patient adjusts the arm to a comfortable angle, and then the latch rod 931 can be inserted back, so that the shell 1 and other components together with the arm can be fixed to the bed at night to prevent the patient from unconsciously turning over and dragging the infusion tube and causing the tube to fall off. When the patient is not receiving an infusion and needs to get up to go to the toilet or move around, the latch rod 931 can be pulled out and the guide plate 91 and the second connecting plate 93 can be separated. When fixation is required, the guide plate 91 and the locking plate 92 can be moved to their original positions and the latch rod 931 can be inserted back.

[0050] like Fig.12 As shown, a lamp tube 81 is also included. Two lamp tubes 81 are respectively fixed to the front and rear parts of the left side of the first connecting plate 31.

[0051] like Fig.12 As shown, a temperature control plate 101 is also included, and the temperature control plate 101 is fixedly connected to the lower part of the inner wall of the shell 1.

[0052] When medical staff need to check the patient's infusion status at night, they can start the lamp 81 to illuminate the infusion position, and then observe the patient's infusion status through the transparent glass cover plate 51 and the observation window on the first connecting plate 31. In this way, medical staff do not need to turn on the headlights in the ward during night inspections, thereby affecting the patient's rest. The presence of the temperature control board 101 can keep the space formed by the shell 1 and the mounting plate 3 and other components at a suitable temperature as much as possible, thereby improving the patient's comfort.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
