Moreover, during the process of the patient holding the one-way pager 33, the patient's finger can be clamped by the blood oxygen clip installed at the bottom of the one-way pager 33 to perform blood oxygen detection and measurement on the patient.

[0043] Referring to Figure 1 、 Figure 8 and Figure 10 As shown, a telescopic rod one 36 is inserted into a fixing frame 35. A telescopic rod two 37 is slidably connected to the inside of the telescopic rod one 36. A hanging frame 38 is fixedly connected to the top of the telescopic rod two 37. A slider 39 is fixedly connected to the bottom of the telescopic rod two 37. A spring four 41 is fixedly connected to the inside of the slider 39. A clamping block two 42 is fixedly connected to one side of the spring four 41. The clamping block two 42 is slidably connected to the inside of the slider 39. Press the clamping block two 42 into the inside of the slider 39, and then pull the telescopic rod two 37 to move inside the telescopic rod one 36, enabling the hanging frame 38 to move to a suitable height.

[0044] Working principle of the present invention: When performing thoracentesis on a patient, first pull out the first telescopic rod 36 from inside the two fixing frames 35. Let the patient sit backwards on the top of the stool 1, and place the patient's two legs into the placement opening 3 at the bottom of the backrest 2. Then the patient can lean the front side of the body against the backrest 2. After that, the patient can rest the chin on the top of the headrest 4. Then support the patient's body through the armrest 34. Then re-insert the bottom of the first telescopic rod 36 into the inside of the two fixing frames 35. Then press the second clamping block 42 to make the second clamping block 42 squeeze the fourth spring 41 into the slider 39. Then pull the second telescopic rod 37 upwards. The second telescopic rod 37 drives the slider 39 to slide inside the first telescopic rod 36. After that, when the second telescopic rod 37 rises to a suitable position, the fourth spring 41 pushes the second clamping block 42 to re-limit with the card slot on the outside of the first telescopic rod 36, so that the hanging rack 38 can move to a suitable height, and the medicine can be hung on the hanging rack 38;

[0045] Turn the screw 18 outside the rotating fixed seat 16 to loosen the clamping of the rotating block 17 at the bottom of the screw 18. Then rotate the tray 26 and the rotating block 17 from the rear side of the backrest 2 to one side of the seat 1. Then pull the pull rod 21 to loosen the insertion of the bottom of the pull rod 21 into one of the jacks outside the rotating seat 25. Rotate the tray 26 to a horizontal angle. Then release the pull on the pull rod 21. The spring three 24 will push the connecting plate 22 and the bottom of the pull rod 21 to re-insert into another jack of the rotating seat 25, so that the tray 26 can be kept horizontally placed. After that, the doctor performs anesthesia and thoracentesis on the patient. During the operation, the doctor can place the items that need to be taken in time on the tray 26. After the operation is completed, pull the pull frame two 8 at the bottom of the seat 1. Under the rotation of multiple auxiliary wheels 9, the pull frame two 8 can be pulled out a part from the bottom of the pull frame one 6. Then after the pull frame two 8 is pulled out to a certain position, at the same time, the pull frame two 8 can drive the pull frame one 6 to slide from the inside of the guide plate 5. After the pull frame one is pulled out a certain distance from the seat 1, it will be limited by the limit post inside the guide plate 5 so that the pull frame one will not be separated from the bottom of the seat 1. Thus, the pull frame one 6 and the pull frame two 8 can be pulled out a part from the bottom of the seat 1. The spring one 11 and the clamping block one 12 inside the fixed block 10 will be clamped with the groove on the inner wall of the chute 7, so that the pull frame two 8 can be kept stable after being pulled out. The patient can lie on the multiple top plates 15 on the top of the pulled-out pull frame one 6 and the pull frame two 8. The multiple top plates 15 will squeeze the spring two 14 at the bottom of the corresponding top plate 15 downward to avoid a large collision between the patient and the pull frame two 8 during the lying-down process. After the patient's operation is over, let the patient sit up again, and put the pull frame two 8 and the pull frame one 6 back into the bottom of the backrest 2. Then the medical staff push the sliding frame 31 to slide outside the guide frame 30, and then press the button 44 so that the button 44 can push the gear disk 49 through multiple push buttons 45, so that the engaging teeth on one side of the gear disk 49 can be engaged with the slot 48 on one side of the push ring 47. Thus, the gear disk 49 can squeeze the spring five 51, so that the plug post 50 can be inserted into the jack outside the guide frame 30, so that the one-way pager 33 can be moved to a position suitable for the patient to press and fixed. And according to the actual operation situation, the sliding frame 31 can be slid out and removed from the outside of the guide frame 30, so that the patient can hold the one-way pager 33 in the hand, which is convenient for the patient to call the medical staff. And the patient can place the finger in the blood oxygen clip at the bottom of the one-way pager 33, and use the photoelectric sensor in the blood oxygen clip to capture the light reflected or transmitted by the hemoglobin molecules in the red blood cells, and then calculate the degree of combination of hemoglobin and oxygen. The calculated blood oxygen saturation data will be transmitted to the display of the blood oxygen clip by wired or wireless means to perform timely blood oxygen detection on the patient. Finally, when the medical staff push the seat 1 and the backrest 2 to move, the driving wheel 29 can assist the medical staff to push the patient. When it is not necessary to move,The movement of the stool 1 can be stopped by the medical casters 27.,
