[0043] Furthermore, the front side of the face mask 100 is connected with an oxygen receiving tube 102 for connecting to the oxygen supply tube of the oxygen pump to supply breathing into the face mask 100; exhaust pipes 103 are connected to both sides of the rear of the face mask 100, and an exhaust port 105 is provided at the connection between the face mask 100 and the exhaust pipe 103. The exhaust pipe 103 is tangentially extended to the side of the face mask 100, so that the exhaled gas flows along the inner wall of the face mask 100 to the exhaust pipe 103 and is smoothly discharged; a gas filter 110 is installed in the exhaust pipe 103, and the interior of the gas filter 110 is filled with activated carbon and medical cotton for adsorbing and purifying and disinfecting the exhaled air before discharging it; the rear of the face mask 100 and the head cover 101 is a vertical plane and a pillow opening 106 is provided on this surface, and a headrest 120 is tightly clamped in the pillow opening 106, so that the patient can lie comfortably on the pillow with the back of the head and can turn the head to the side to rest.

[0044] Furthermore, the size of the head cover 101 is larger than that of the face cover 100. The bottom of the face cover 100 is connected to a collar 104. The inner diameter of the collar 104 is 60-62 cm, which is larger than the head circumference of a normal adult, so that the head cover can be put on smoothly. The top surface of the head cover 101 is provided with a threaded hole 1011 coaxially arranged with the collar 104, and the rotating part 200 is sleeved and matched with the collar 104.

[0046] Furthermore, the inner wall of the neck sleeve 220 is rotatably sleeved with a rotating sleeve 221, and the silicone sleeve 222 is bonded to the inner wall of the rotating sleeve 221. The inner side of the silicone sleeve 222 is corrugated, that is, the neck is sealed by the irregular silicone sleeve 222 to prevent exhaled air from leaking out from here.

[0047] In addition, an auxiliary support portion 300 is provided below the face mask 100 to support the face mask 100 so that it is mounted outside the head, so as to prevent the face mask 100 from pressing on the shoulders when the patient stands up and walks; the auxiliary support portion 300 includes a pair of shoulder support rods 310 for clamping the face mask 100 and suspending it on the shoulders, and an arm set 320 for pulling the shoulder support rods 310 to prevent them from shaking; that is, the shoulder support rods 310 are supported by the shoulders to lift the face mask 100 as a whole and mount it on the periphery of the head, and the arm set 320 is used to clamp the shoulder-arm connection to stabilize the shoulder support rods 310 and support it on the shoulders.

[0048] Specifically, a semi-circular support ring 311 is provided at one end of the shoulder support rod 310, and clamping plates 312 are embedded in the bottom surfaces of the two outer ends of the support ring 311. The front and rear clamping plates 312 are used to clamp the upper torso of the body to further stabilize the shoulder support rod 310; a shoulder pad 313 is bonded to the bottom surface of the shoulder support rod 310, and the shoulder pad 313 is made of silicone material, so that the shoulder support is comfortable.

The elastic band 321 is used as a buffer zone for traction to ensure that the patient's shaking when walking is buffered and transmitted, and energy is consumed through the friction between the arm sleeve group 320 and the body; the arm clamp ring 322 is a hollow semi-ring structure, and the armpit ring 323 is a solid ring with a central angle greater than 180 degrees, so that the two ends of the armpit ring 323 can be inserted into the two ends of the arm clamp ring 322 at the same time, forming a state of clamping the arm; a dial wheel 3223 is embedded in the outer wall of one end of the arm clamp ring 322, and the dial wheel 3223 is rotated to roll the armpit ring 323 and the arm clamp ring 322 to form a full circle, so that the adjustment of the arm clamp ring 322 is easy and convenient.

[0050] Furthermore, an arcuate opening 3221 is provided on the outer side surface of the front end of the clamp arm ring 322, and supporting rings 3222 are symmetrically provided on the upper and lower sides of the arcuate opening 3221. The dial wheel 3223 is rotatably connected to a pair of supporting rings 3222 by pins. A silicone ring is provided on the outer sleeve of the dial wheel 3223, that is, the silicone ring passes through the arcuate opening 3221 and rolls to contact the armpit ring 323, and then the friction force is used to drive the armpit ring 323 to move in the clamp arm ring 322 until it forms a circle and covers the arm.

[0051] Furthermore, a concave hole 3111 is provided at both ends of one support ring 311, and a protrusion 3112 is provided at both ends of the other support ring 311. The protrusion 3112 is snap-fitted with the concave hole 3111, so that the two support rings 311 form a whole ring to support the face mask 100; a pair of support rings 311 are snap-fitted with the sleeve ring 104, and a protruding ring 1041 is provided on the outer side of the middle part of the sleeve ring 104. The protruding ring 1041 is used to limit the support ring 311 so that the sleeve ring 104 does not contact the shoulder.

[0052] Furthermore, a pillow pad 121 is bonded to the inner side of the headrest 120 and is snap-fitted with the pillow opening 106. The pillow pad 121 is made of a flexible material and is filled with an adsorbent, such as a latex pad or a memory foam pad. The adsorbent, such as activated carbon, activated carbon fiber and zeolite, can adsorb viruses and microbial gases. A sleeve frame 107 is provided on the rear side of the face mask 100 and the head mask 101 and outside the pillow opening 106. The outer side of the headrest 120 is snap-fitted with the sleeve frame 107, so that the headrest 120 is easy to replace and is sealed and snap-fitted with the pillow opening 106. Snap-ons 122 are provided on both sides of the top of the headrest 120 to facilitate the fingers to clamp the snap-ons 122 and take and put the headrest 120.

[0053] The present invention also provides a method for using the patient respiratory isolation device, which includes the following steps:

[0054] S1. First install the gas filter 110 and the headrest 120 onto the face mask 100, and then put it on the patient's head;

[0055] S2, then rotate the screw rod 230 to drive the top pressing block 210 to press the top of the head;

[0056] S3, connect the air pipe of the oxygen pump to the oxygen receiving pipe 102, and open the oxygen valve to supply oxygen for breathing. The gas exhaled by the patient flows along the inner wall curvature of the mask 100 to the exhaust pipe 103, and is purified by the gas filter 110 before being discharged;

[0057] S4, then clamp a pair of shoulder support rods 310 on both sides of the collar 104 and put them on the shoulders;

[0058] S5, then pass the elastic band 321 around the shoulder and put the arm clamp ring 322 and the armpit ring 323 around the arm;

[0059] S6, the patient can stand up and walk, and turn his head through the free rotation of the top pressing block 210 and the rotating sleeve 221;

[0060] S7. When the patient lies down to rest, the back of the head rests on the soft and flat headrest 120, and the head can be turned sideways, which ensures that the patient wears protection at all times without affecting the patient's normal activities and rest.
