Both of the two third magnets 24 are adsorbed in the fixed seat 23. Two fixing bars 25 are fixedly provided between the two third magnets 24. Two guide rods 26 are slidably arranged through one side of the fixing bar 25. The same sliding bar 28 is fixedly provided at one end of the two guide rods 26. A tension spring 27 is sleeved on the outer wall of the guide rod 26. The two ends of the tension spring 27 are fixedly connected to the relatively close sides of the sliding bar 28 and the fixing bar 25 respectively. Two insertion blocks 29 are fixedly provided on the outer side of the sliding bar 28. Jacks 30 corresponding to the two groups of insertion blocks 29 are opened on both sides of the fixed seat 23, so that the protection box 2 can be fixed on the belt 1.

[0039] A partition 14 is provided inside the protection box 2, dividing the protection box 2 into two independent spaces, which are respectively used for placing an infusion pump 15 and a blood pressure detector 16. Such a design enables the infusion pump 15 and the blood pressure detector 16 to be placed in the protection box 2 orderly, avoiding mutual interference and also facilitating the patient to access them at any time. Second U-shaped openings 19 corresponding to the connection heads of the infusion pump 15 and the blood pressure detector 16 are respectively opened on both sides of the protection box 2 for connecting external devices such as wires or sensors.

[0040] On the outer side of the protection box 2, a cover plate 3 is rotatably provided. The cover plate 3 is connected to the protection box 2 by a hinge. After the adjustment of the infusion pump 15 and the blood pressure detector 16 is completed, the cover plate 3 can be rotated to cover the opening of the protection box 2 to protect the internal devices from damage or contamination. In order to fix the cover plate 3 more firmly, first magnets 17 are embedded on both sides of the cover plate 3, and limit blocks 20 are fixedly provided on both sides of the protection box 2. Second magnets 21 corresponding to the first magnets 17 are embedded on one side of the limit blocks 20, and the cover plate 3 is closely attached to the protection box 2 by the suction force of the magnets.

[0041] Meanwhile, a wedge bar 22 that cooperates with the cover plate 3 is slidably arranged in the limit block 20. One end of the wedge bar 22 is fixedly connected to the corresponding sliding bar 28. Two first U-shaped openings 18 corresponding to the connecting heads are formed in one side of the cover plate 3. When the cover plate 3 protects the infusion pump 15 and the blood pressure detector 16, it can push the wedge bar 22 to move outwards, so as to pull the insertion block 29 into the corresponding jack 30.

[0042] On the other side of the waistband 1, a wristband 42 is provided. The wristband 42 is connected to the connecting head of the blood pressure detector 16 through a wire. The patient can wear the wristband 42 on the wrist to detect blood pressure data in real time and transmit the data to the blood pressure detector 16 for processing and display.

[0043] A first airbag 4 is fixedly arranged at the top of the waistband 1. The first airbag 4 is made of a soft and elastic material and can only expand in the up and down directions. On one side of the protection box 2, an extension plate 9 is provided. An air pump 7 is arranged on the extension plate 9. The air pump 7 is connected to the first airbag 4 through an adjustment mechanism for controlling the intake and exhaust of the first airbag 4. Specifically, the adjustment mechanism includes a first connecting pipe 10 and a second connecting pipe 12. The top end of the first connecting pipe 10 is connected to the first airbag 4 and the bottom end is sealed; the second connecting pipe 12 is inserted on the outer wall of the first connecting pipe 10 and is fixedly connected to a connecting seat 31. The connecting seat 31 is fixed on the extension plate 9, and an adjustment block 13 is slidably arranged on one side of the extension plate 9. Two channels are formed in the adjustment block 13: a first channel 32 and a second channel 33, which respectively match the second connecting pipe 12. The intake end of the air pump 7 is connected to the second channel 33 through a pipe, and the exhaust end is connected to the first channel 32 through a pipe. In order to control the movement of the adjustment block 13 to switch between the first channel 32, the second channel 33 and the second connecting pipe 12, an electric push rod 11 is arranged on one side of the extension plate 9, and its output end is fixedly connected to the adjustment block 13. By controlling the telescopic movement of the electric push rod 11, the adjustment block 13 can be pushed to slide on the extension plate 9, so as to change the relative positions of the first channel 32 and the second channel 33 with the second connecting pipe 12, and further realize the control of the intake and exhaust of the first airbag 4. At the same time, the electric push rod 11, the air pump 7 and the blood pressure detector 16 are connected to the same controller, and the air pump 7 and the electric push rod 11 are started by using the value of the blood pressure detector 16. When the blood pressure rises, the air pump 7 is started to inflate the first airbag 4 and the second airbag 5, and vice versa for deflation.

[0044] At the top of the first airbag 4, a second airbag 5 is provided, and the second airbag 5 is in communication with the first airbag 4. At the top end of the first airbag 4, a collection bag 8 is provided for containing the vomit of the patient. In order to automatically open and close the collection bag 8, two rotating seats 36 are provided at the top end of the first airbag 4, and a rotating shaft 38 is fixedly provided on the rotating seat 36. A rotating frame 6 is rotatably sleeved on the outer wall of the rotating shaft 38, and one side of the two rotating frames 6 is fixedly connected to the top end of the collection bag 8. On one side of the rotating frame 6, a pull rope 37 is provided, and the other end of the pull rope 37 is connected to the middle section of the first airbag 4. When the first airbag 4 expands, it will pull the pull rope 37, thereby driving the rotating frame 6 to rotate around the rotating shaft 38, so that the collection bag 8 is opened. In order to facilitate the entry of vomit into the collection bag 8, an extension part 35 is provided at the top end of the second airbag 5, and the bottom end of the extension part 35 is fixedly connected to the top end of the collection bag 8. When the vomit sprays out of the patient's mouth, it will enter the collection bag 8 along the extension part 35. In order to maintain the airtightness of the collection bag 8, a torsion spring 39 is sleeved on the outer wall of the rotating shaft 38, and both ends of the torsion spring 39 are fixedly connected to the mutually close sides of the rotating seat 36 and the rotating frame 6. When the first airbag 4 exhausts air, the torsion spring 39 will drive the rotating frame 6 to rotate back to its original position, so that the collection bag 8 is closed.

[0045] In addition, in order to increase the comfort of the patient, a plurality of massage balls 41 are fixedly provided inside the first airbag 4. These massage balls 41 are made of a soft and elastic material. When the first airbag 4 expands, the massage balls 41 will closely adhere to the patient's abdomen and gently massage it, which helps to relieve the discomfort and pain brought by chemotherapy.

[0046] When the portable protection device for oncology chemotherapy patients is in use, the waist belt 1 is worn on the patient, so that the first airbag 4 is stuck on the patient. Then, the infusion pump 15 and the blood pressure detector 16 are respectively inserted into the protection box 2, so that their plugs are located in the corresponding second U-shaped openings 19. At the same time, the wristband 42 is worn on the patient's wrist.

[0047] Then, the third magnet 24 is placed in the fixed seat 23, and the infusion pump 15 and the blood pressure detector 16 are debugged. After the debugging is completed, the cover plate 3 is pulled to protect the infusion pump 15 and the blood pressure detector 16 until the first U-shaped opening 18 is stuck on the corresponding plug, which can limit the infusion pump 15 and the blood pressure detector 16. At this time, the first magnet 17 is adsorbed on the corresponding second magnet 21, and during the adsorption process, it can squeeze the wedge 22 to move outward. The outward movement of the wedge 22 can drive the sliding bar 28 to move outward. The outward movement of the sliding bar 28 can drive the plug block 29 to insert into the corresponding jack 30, which can further fix the protection box 2 on the fixed seat 23.

[0048] Then, the medicine is pumped into the patient through the infusion pump 15, and at the same time, the blood pressure of the patient is detected in real time through the blood pressure detector 16 and the wristband 42. When the patient's blood pressure rises and he / she wants to vomit and faint, the air pump 7 is started through the controller. At this time, the exhaust end of the air pump 7 is connected to the first channel 32, and the first channel 32 is connected to the second connecting pipe 12. The discharged gas can enter the first airbag 4 and the second airbag 5 through the second connecting pipe 12 and the first connecting pipe 10, causing the first airbag 4 and the second airbag 5 to expand, so as to protect the patient. During the expansion process of the first airbag 4, the massage ball 41 can be driven to move upward. During the upward movement of the massage ball 41, the patient's abdomen can be massaged and squeezed. During the upward expansion process of the second airbag 5, the extension part 35 can be driven to open, so that the top end of the second airbag 5 is located at the patient's chin. At the same time, during the expansion process of the first airbag 4, the rotating frame 6 can be pulled by the pull rope 37 to rotate on the rotating seat 36, and the collection bag 8 can be opened. At this time, when the patient vomits, he / she can directly vomit into the collection bag 8 and it will not leak out.

[0049] When the blood pressure returns to normal, the electric push rod 11 is started to retract through the controller. During the retraction process of the electric push rod 11, the adjusting block 13 can be driven to move upward. The upward movement of the adjusting block 13 can drive the second channel 33 to move upward, so that the second channel 33 is connected to the second connecting pipe 12. At this time, the air pump 7 is started. The exhaust end of the air pump 7 is disconnected from the second connecting pipe 12, and the intake end of the air pump 7 is connected to the second connecting pipe 12, so that the gas in the first airbag 4 and the second airbag 5 can be pumped out to make them return to normal. During the retraction process of the first airbag 4, the rotating frame 6 can be reset and rotated under the action of the torsion spring 39 to seal the top end of the collection bag 8.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
