[0012] Beneficial effects of the present invention:

[0013] The present invention provides an elastic head, a movable annular magnet, a fixed annular magnet, a pressure sensor, a feedback tube, an elastic layer, a feedback groove, etc. During the process of inserting the device into the body, the distance between the movable annular magnet and the fixed annular magnet in the elastic head changes continuously, the pressure sensor can detect the posture change of the movable annular magnet, and feed back the pressure of the movable annular magnet to the feedback groove of the alignment angle, and by controlling the liquid content of the feedback groove of the corresponding angle, the pressure of the elastic head is transmitted to the surface of the elastic layer, thereby providing the operator with intuitive tactile feedback with direction and pressure value, thereby improving the insertion efficiency of the device.

[0014] The laryngeal mask with tactile feedback of the present invention is provided with an inner bag, an outer bag and a variable bend pipe. The variable bend pipe is elastic and can adapt to the structure of the human body. When the variable bend pipe is bent, the liquid in the inner bag cavity on the inner side of the bend of the variable bend pipe flows freely to the outer bag cavity on the outer side of the bend through the circulation pipe. The switch closes the channel of the circulation pipe to block the circulation of the liquid between the inner bag and the outer bag, thereby playing a shaping function on the bending degree of the variable bend pipe and reducing the pressure of the variable bend pipe on the patient.

[0015] The laryngeal mask with tactile feedback of the present invention is provided with an elastic tube, an elastic support layer, an expansion bag, etc. The elastic tube has a smooth surface, has low friction with the human mucosa, and reduces the possibility of abrasion. The elastic support layer is elastic. By controlling the liquid content in the holes of the elastic support layer, the volume of the elastic support layer expanding outward is controlled. The use of the elastic support layer improves the softness of the surface of the elastic tube and reduces the pressure of the elastic tube on the patient. On the other hand, by periodically controlling the expansion degree of the elastic support layer, the surface of the elastic tube can periodically press the nearby mucosa to accelerate blood circulation.

For the convenience of description, the directions mentioned below are defined as follows: the up, down, left, right, front, and back directions mentioned below are the same as Figure 1 The up-down, left-right, front-back directions of the projection relationship itself are consistent.

[0025] Combined with Figure 1-6The laryngeal mask with tactile feedback comprises an airbag 13, a variable bend tube 10, and an inflation tube 12. The distal end of the variable bend tube 10 is connected with a connecting tube 11. The inner wall of the variable bend tube 10 is provided with an inner bag 14 and an outer bag 15. The inner bag 14 and the outer bag 15 are oppositely distributed. A flow tube 16 is connected between the inner bag 14 and the outer bag 15. A switch is provided in the flow tube 16. An elastic head 31 is provided at the lower tip of the airbag 13. A movable annular magnet 33 is provided in the elastic head 31. A fixed annular magnet 34 is provided in the elastic head 31. The fixed annular magnet 34 is mutually connected with the fixed annular magnet 34. Repulsion, the elastic head 31 is provided with a pressure sensor 35 near the fixed annular magnet 34, and the pressure sensors 35 are distributed around the axis circumference of the movable annular magnet 33. A feedback tube 36 is provided at one end of the variable bend tube 10 close to the airbag 13, and an elastic layer 37 is provided on the outside of the feedback tube 36. A feedback groove 38 is formed between the elastic layer 37 and the outer wall of the feedback tube 36. The feedback grooves 38 are distributed around the axis circumference of the feedback tube 36. The number of the feedback grooves 38 is consistent with the number of the pressure sensors 35. A movable block 40 is provided on the side of the feedback tube 36 close to the feedback groove 38, and the movable block 40 can squeeze the space of the feedback groove 38.

[0026] When using the device, hold the connection between the variable bend tube 10 and the airbag 13, with the elastic layer 37 pressed against the fingers, and implant the device into the patient's throat according to the prescribed operating method, so that the upper side of the airbag 13 covers the trachea, and the lower end of the airbag 13 is inserted into the esophagus. During the insertion of the device to the specified position, the elastic head 31 continues to contact the patient's skin. The elastic head 31 has soft elasticity. The elastic head 31 drives the movable annular magnet 33 to deviate relative to the fixed annular magnet 34, and the repulsive force between the movable annular magnet 33 and the fixed annular magnet 34 increases. The pressure sensor 35 at the corresponding position detects the pressure on the fixed annular magnet 34. The angle and pressure of the contact between the elastic head 31 and the patient at this time can be determined based on the detection of the pressure sensor 35. 35, the increased pressure at the corresponding angle is converted into the distance that the movable block 40 moves outward. The movable block 40 at a certain angle squeezes the feedback groove 38 outward, thereby squeezing the elastic layer 37 at the corresponding angle outward, thereby reacting to the operator's fingers, providing the operator with tactile feedback with direction and pressure sense, which is convenient for the operator to judge the position of the device. The variable bend 10 is elastic and can adapt to the human body structure. When the variable bend 10 is bent to a certain extent, the liquid in the inner capsule 14 cavity on the inner side of the bend of the variable bend 10 flows freely to the outer capsule 15 cavity on the outer side of the bend through the circulation tube 16. The switch closes the circulation tube 16 to block the circulation of the liquid between the inner capsule 14 and the outer capsule 15, which plays a certain shaping function and can reduce the pressure of the variable bend 10 on the patient.

The volume of the elastic support layer 18 expanding outward is controlled by controlling the liquid content in the holes of the elastic support layer 18. The diameter of the elastic tube 17 is controlled by controlling the expansion degree of the elastic support layer 18. The use of the elastic support layer 18 improves the softness of the surface of the variable bend tube 10 and reduces the pressure of the variable bend tube 10 on the patient. On the other hand, by periodically controlling the expansion degree of the elastic support layer 18, the elastic tube 17 can periodically press the nearby mucosa to accelerate blood circulation.

[0032] The slider 24 slides in the slide groove 22, thereby realizing the function of controlling the switch of the circulation tube 16 and the cross-sectional area of ​​the circulation port. When the circulation tube 16 is closed, the bending degree of the variable bend tube 10 is fixed.
