Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Examples of the above embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0023] In the present invention, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example 1: Refer to Figures 1 - 3 、 Figure 6, the present invention provides a technical solution: a wearable infrared B-ultrasound intravenous monitor for chemotherapy, including an adjustment mechanism 1. The adjustment mechanism 1 includes a first arc-shaped block 101. A first sliding frame 112 is provided at the bottom of the first arc-shaped block 101. A second groove 113 is formed at the bottom of the first sliding frame 112. An auxiliary mechanism 2 is provided at the bottom of the first sliding frame 112; The auxiliary mechanism 2 includes: A first rotating frame 201, the first rotating frame 201 is slidably connected to the outer surface of the first sliding frame 112. A first auxiliary wheel 202 is rotatably connected to the top of the first rotating frame 201 through a rotating shaft. The first auxiliary wheel 202 is rotatably connected to the inner wall of the second groove 113. A through hole 203 is formed on the outer surface of the first rotating frame 201; A rotating rod 204, one side outer wall of the rotating rod 204 close to the first rotating frame 201 penetrates through the first rotating frame 201 and is fixedly connected to a first connecting rod 205. The rotating rod 204 is rotatably connected to the inner wall of the first rotating frame 201. When a chemotherapy patient wears this device, first fix the upper arm area through the adjustment mechanism 1. Subsequently, the first rotating frame 201 rotates by means of the first auxiliary wheel 202 on the inner wall of the second groove 113, so that the forearm of the chemotherapy patient can rotate freely after wearing. By the rotating connection between the rotating rod 204 and the first rotating frame 201, the freedom of rotation of the patient's arm is further improved.

[0025] A second auxiliary wheel 206 is rotatably connected to one side outer wall of the first connecting rod 205 close to the through hole 203 through a rotating shaft. The second auxiliary wheel 206 is rotatably connected to the inner wall of the through hole 203. One side outer wall of the rotating rod 204 away from the first connecting rod 205 is fixedly connected to a first connecting ring 207. A third groove 208 is formed on the outer surface of the first connecting ring 207. One side outer surface of the first connecting ring 207 away from the third groove 208 is fixedly connected to a second connecting rod 209. A hydraulic rod 210 is fixedly connected to the inner wall of one side of the second connecting rod 209 away from the first connecting ring 207. The output end of the hydraulic rod 210 is fixedly connected to a second arc-shaped block 211. A B-ultrasound monitor 212 is fixedly connected to the inner wall of the second arc-shaped block 211. A warning light 213 is fixedly connected to the outer surface of the second arc-shaped block 211. The hydraulic rod 210 is used to push the second arc-shaped block 211 to move towards the forearm side of the patient. When the patient's forearm passes through the first connecting ring 207 and rotates, the first connecting ring 207 drives the second auxiliary wheel 206 on the outer wall of the first connecting rod 205 to rotate on the inner wall of the through hole 203 through the rotating rod 204. During chemotherapy intravenous injection, the hydraulic rod 210 pushes the second arc-shaped block 211 to move towards the patient's forearm vein area. At the same time, the B-ultrasound monitor 212 monitors the vein condition in real time. If no drug flow in the blood vessel is detected continuously during the monitoring process, the warning light 213 will change from green to red and flash to give an alarm to remind medical staff and patients.

[0026] When a patient undergoes intravenous chemotherapy, if the drug is not accurately injected into the blood vessel, it may cause chemotherapy drug extravasation and affect the treatment effect. Therefore, by setting up an adjustment mechanism 1, the second arc-shaped block 211 is pushed by the hydraulic rod 210 to move towards the patient's forearm vein area, and at the same time, the vein is monitored in real time by the B-ultrasound monitor 212 to determine whether the drug is accurately injected into the blood vessel.

[0027] Embodiment 2: Please refer to Figures 4 - 5 , on the basis of Embodiment 1, the present invention provides a technical solution: a first fixed shaft 114 is fixedly connected to the outer wall of the top of the first sliding frame 112. One end of the first fixed shaft 114 away from the first sliding frame 112 penetrates through the first arc-shaped block 101 and is fixedly connected to a first spring 115. One end of the first spring 115 close to the first sliding frame 112 is fixedly connected to the first arc-shaped block 101. The first fixed shaft 114 is used to improve the stability of the first sliding frame 112 during the sliding process. When different chemotherapy patients wear this device, considering the differences in the lengths of the patient's upper arm and forearm, the position of the first fixed shaft 114 can be adjusted by pulling the first sliding frame 112, so as to ensure that the connection between the rotating rod 204 and the first rotating frame 201 is aligned with the patient's elbow.

[0028] A first groove 102 is formed on the outer surface of the first arc-shaped block 101. A second flexible pad 106 is fixedly connected to the inner wall of the first arc-shaped block 101 on the side away from the first groove 102. The outer wall of the first arc-shaped block 101 is rotatably connected to an adjustment plate 104 through a rotating shaft. A first flexible pad 105 is fixedly connected to the inner wall of the adjustment plate 104. An air vent groove 103 is formed on the outer wall of the adjustment plate 104. A connecting tooth 107 is fixedly connected to the outer surface of the adjustment plate 104 close to the air vent groove 103. A connecting shaft 111 is fixedly connected to the inner wall of the first flexible pad 105 close to the first groove 102. The connecting shaft 111 is slidably connected to the inner wall of the first groove 102. The first groove 102 is used to limit the flipping radian of the adjustment plate 104 through the connecting shaft 111. A motor 108 is fixedly connected to the outer wall of the top of the first arc-shaped block 101. The output end of the motor 108 penetrates through the first arc-shaped block 101 and is fixedly connected to a rotating shaft 109. A gear 110 is fixedly connected to the outer surface of the rotating shaft 109. The gear 110 is meshed with the connecting tooth 107. The motor 108 flips the adjustment plate 104 through the gear 110. When fixing the upper arm area of different patients, the motor 108 drives the gear 110 to be meshed with the connecting tooth 107 on the outer surface of the adjustment plate 104 through the rotating shaft 109, so that the adjustment plate 104 flips along the outer surface of the first arc-shaped block 101. During the flipping process of the adjustment plate 104, the adjustment plate 104 slides on the inner wall of the first groove 102 through the connecting shaft 111, and at the same time, the first flexible pad 105 and the second flexible pad 106 on its surface contact the patient's upper arm to achieve adaptive fixation.

[0029] When chemotherapy patients wear this device, there are differences in the lengths and thicknesses of the upper and lower arms of different patients' arms, resulting in greater difficulty in wearing and instrument positioning. Therefore, an adjustment mechanism 1 is provided. The adjustment plate 104 is driven by the motor 108 to flip, so that it slides along the outer surface of the first arc-shaped block 101, thereby shrinking the space inside the adjustment plate 104 and the first arc-shaped block 101. During this process, the first flexible pad 105 on the inner wall of the adjustment plate 104 and the second flexible pad 106 on the inner wall of the first arc-shaped block 101 come into contact with the patient's upper arm, and the clamping and fixing of different patients' upper arms are realized through adaptive adjustment, improving the stability after wearing.

[0030] Embodiment 3: Please refer to Figures 7 - 8 , on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: A monitoring mechanism 3 is provided on the side of the first connecting ring 207 away from the rotating rod 204. The monitoring mechanism 3 includes a second rotating frame 301 slidably connected to the third groove 208. The outer wall of the second rotating frame 301 is provided with a first sliding block 302. The inner wall of the first sliding block 302 is fixedly connected with a first infrared monitor 303. The outer wall of the first sliding block 302 close to the second rotating frame 301 is fixedly connected with a second fixed shaft 304. One end of the second fixed shaft 304 away from the first sliding block 302 penetrates through the second rotating frame 301 and is fixedly connected with a limiting block 305. The outer wall of the limiting block 305 close to the first sliding block 302 is fixedly connected with a second spring 306. The side of the second spring 306 away from the limiting block 305 is fixedly connected with the second rotating frame 301. The second fixed shaft 304 is used to limit the sliding distance of the first sliding block 302 through the limiting block 305. Since there are differences in the distances from the wrists to the elbows of different patients, the first sliding block 302 can pull the limiting block 305 to move toward the second rotating frame 301 through the second fixed shaft 304, thereby adjusting the distance between the first sliding block 302 and the second rotating frame 301, so as to facilitate the accurate positioning of the first sliding block 302 at the patient's wrist.

[0031] The inner wall of the first sliding block 302 is slidably connected to a second sliding block 307. The inner wall of the second sliding block 307 is fixedly connected to a second infrared monitor 308. The outer surface of the second sliding block 307 is fixedly connected to a pulling rope 309. The outer wall of the second sliding block 307 on the side away from the pulling rope 309 is fixedly connected to a third fixed shaft 310. The third fixed shaft 310 passes through the first sliding block 302 and is fixedly connected to an elastic component 311. The side of the elastic component 311 close to the second sliding block 307 is fixedly connected to the first sliding block 302. The elastic component 311 is used to complete the reset of the second sliding block 307. When it is necessary to monitor the patient's wrist, pull the pulling rope 309 to make the second sliding block 307 slide upward along the inner wall of the first sliding block 302. After the patient's hand passes through the space between the first sliding block 302 and the second sliding block 307, release the pulling rope 309. The second sliding block 307 moves toward the first sliding block 302 under the action of the elastic component 311. At this time, the second infrared monitor 308 and the first infrared monitor 303 are used to monitor the venous area of the patient's wrist.

[0032] The outer surface of the first sliding block 302 is fixedly connected to a first elastic rope 312. The outer wall of the first elastic rope 312 on the side away from the first sliding block 302 is fixedly connected to a support plate 313. The outer surface of the support plate 313 on the side away from the first elastic rope 312 is fixedly connected to a second elastic rope 314. One end of the second elastic rope 314 away from the support plate 313 is fixedly connected to a finger ring 315. When the patient wears the device, put the finger ring 315 on the outer surface of the corresponding finger, make the support plate 313 contact the back of the hand. The support plate 313 pulls the first sliding block 302 to move toward the patient's wrist through the first elastic rope 312, so as to facilitate the positioning of the first sliding block 302 on the patient's wrist.

[0033] When it is necessary to monitor the patient's veins, if the vein condition is detected only at a single site, there may be errors, resulting in false alarms of the warning lamp 213. Therefore, by setting the monitoring mechanism 3, the first infrared monitor 303 and the second infrared monitor 308 can be used to simultaneously monitor the veins on the outer surfaces of both sides of the patient's wrist, so as to improve the judgment accuracy of whether the drug is flowing in the vein.
