As an embodiment of the present invention, as shown in FIGS. 5 and 6, a ring cylinder 93 is fixedly installed inside the second cavity 84, and the draft tube 91 penetrates the ring cylinder 93 and extends to the lower end thereof by 5 to 8 cm.

When the device works, the pressing bag 42 expands to enable the first frame body 8 and the second frame body 81 to be separated up and down, the drainage tube 91 moves upwards along with the first frame body 8, the water outlets 92 on two sides of the drainage tube 91 move into the annular cylinder 93, the water outlets 92 are closed, liquid alcohol can be temporarily stopped being supplied, after the pressing bag 42 is reset and contracted, the first frame body 8 is close to the second frame body 81, the lower end of the drainage tube 91 penetrates through the annular cylinder 93, the water outlets 92 can continuously supply alcohol into the second cavity 84, liquid alcohol can be conveniently added into the first cavity 83 and the second cavity 84, and the situation that the outside of the pressing bag 42 is wet due to the fact that too much alcohol is sprayed out of the first cavity 83 is reduced.

The working principle is as follows: when the device works, a user sits normally, the device is placed on a workbench, firstly, the user can roll the cuff of one side arm upwards until the arm is completely exposed, then the arm is obliquely inserted into the circular groove 21 until the arm part penetrates into the circular groove 21, when the user inserts the arm into the circular groove 21, clothes outside the arm can be dragged by the hook pieces 73 of the upper and lower abutting components 7, the circular groove 21 with the oblique structure design conforms to the natural state when the arm is inserted, the support for the hand of the user is convenient to detect, the fatigue caused by long-time oblique placement of the arm is reduced, when the arm penetrates through the inner ring 41, the four groups of limiting components 5 and the abutting bag 42 are respectively staggered and limited around the arm, then, the display screen 3 is operated, the inside of the display screen 3 sends an instruction, the inside of the inner ring 43 is rapidly inflated through the air inlet pipe 31, the air respectively enters the abutting bag 42 sequentially through the inner ring 43, the four sets of pressure-resisting bags 42 are filled with gas to stretch and elongate, and are respectively pressed on the periphery of the arm of the user in a resisting way, the pressure is accumulated again when the radial artery pulsation disappears, then the air valve is released to reduce the pressure at the speed of 2-3 kpa per second, so that the blood pressure reading can be obtained, after the blood pressure detection is finished, the air valve can be released, the air in the inner ring tube 43 and the pressure-resisting bags 42 is exhausted, the pressure-resisting bags 42 return to the natural state, then the inner ring 41 rotates along the inner part of the ring groove 511 until the pressure-resisting bags 42 rotate to the inner part of the U-shaped clamping frame 52, then the switch is started again, the pressure-resisting bags 42 are inflated and expanded and resist the inner part of the U-shaped clamping frame 52, further the first frame body 8 and the second frame body 81 of the U-shaped clamping frame 52 are separated under the resisting force of the second spring 82 and the pressure-resisting bags 42, at the moment, the push plugs 802 and the struts 801 movably arranged in the second frame body 81 move upwards along with the downward direction of the second frame body 81, suction is generated in the first cavity 83, disinfection alcohol dripped into the second cavity 84 can be sucked in, then the air valve can be released, the air in the inner ring pipe 43 is exhausted, the pressing bag 42 contracts, the second frame 81 stops being pressed and rebounds upwards under the action of the second spring 82, at the moment, the supporting rod 801 and the pushing plug 802 push inwards in the first cavity 83 again, so that the alcohol dripped into the first cavity can be sprayed outwards through the spraying opening 811, the sprayed alcohol vertically upwards aligns to the outer surface of the lower end of the pressing bag 42, the area is in direct contact with the skin of a human body, and the alcohol spraying can disinfect the area for later use.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
