It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

In one preferred embodiment of the present application, as shown in fig. 1 to 4, a face mask for sealing by inhalation comprises a mask body 1 and a connection rope 3, wherein both ends of the connection rope 3 are connected to both sides of the mask body 1, so that when the mask body 1 is used, the face of a patient can be worn on the mask body 1 through the connection rope 3. In order to improve wearing comfort level and the laminating effect of face guard body 1, the edge connection of face guard body 1 has cushion 2, cushion 2's both sides all are provided with connecting portion 21, connecting portion 21's inside is provided with sliding cavity 210, the inseparable slidable mounting in sliding cavity 210 in both ends of connecting rope 3, thereby when sliding cavity 210's inside atmospheric pressure changes, the tip of connecting rope 3 can slide along sliding cavity 210 along with the change of atmospheric pressure, and then can drive connecting rope 3 and strain or relax. Thereby when the patient is breathing in, can tighten up the connection rope 3 through the atmospheric pressure change of sliding chamber 210 to make cushion 2 produce deformation through the pressurized with the face, and then paste face mask body 1 and each position of patient's face tightly, in order to guarantee that the patient is breathing in, form airtight space between face mask body 1 and the patient. And when the patient when exhaling, can relax the connection rope 3 through the atmospheric pressure change of sliding chamber 210 to make cushion 2 recover under the elasticity effect of self, and then make and produce the gap between face guard body 1 and the patient's face, mix the gas of patient's exhalation and external world through the gap.

It is understood that the number of the connecting ropes 3 may be one or two. For the wearing condition of the two connection ropes 3, the two connection ropes 3 are respectively connected with the sliding parts 21 at two sides of the mask body 1 through one ends, and the other ends of the two connection ropes 3 are bolted to each other.

In this embodiment, as shown in fig. 1, 2 and 4, an oxygen interface 100 is provided on the outer side of the mask body 1, and a respiration sensor 4 is installed on the inner side of the mask body 1; the oxygen interface 100 is connected with the air pump 10 through the ventilation tube 9, and the air pump 9 is electrically connected with the respiration sensor 4. Thereby when the patient breathes in, air pump 10 can start according to the signal that respiratory sensor 4 detected, and then can follow the airtight space of breather pipe 9 leading-in to face guard body 1 and patient face formation with the oxygen in the oxygen storage jar 11 to make and to guarantee through the airtight space of face guard body 1 and patient face formation that leading-in oxygen is mostly inhaled to the lung by the patient, with the oxygen inhalation rate that improves the patient.

In the present embodiment, the air pump 10 and the oxygen storage tank 11 are conventional in the art; the respiration sensor 4 is used for detecting the respiration state of the patient, so the respiration sensor 4 is positioned in the direction of the mouth and nose exhalation of the patient; the oxygen interface 100 is disposed directly over the nose and mouth of the patient.

In this embodiment, as shown in fig. 4, the ventilation tube 9 is in communication with the oxygen interface 100 through the second control valve 82, and the second control valve 82 is electrically connected to the respiration sensor 4. Therefore, when a patient inhales, the second control valve 82 can control the second control valve 82 to communicate the vent pipe 9 with the oxygen interface 100 according to the detection signal of the breathing sensor 4, so that oxygen in the oxygen storage tank 11 can be introduced into the closed space formed by the mask body 1 and the face of the patient through the air pump 10. And when the patient exhales, second control valve 82 can control second control valve 82 to directly isolate breather pipe 9 from oxygen interface 100 according to the detected signal of breathing sensor 4, so that when the patient inhales again, the oxygen in oxygen storage tank 11 can be rapidly introduced into the airtight space formed by mask body 1 and the face of the patient.

It can be understood that, when the oxygen supply of the patient is performed, the oxygen storage tank 11 is always communicated with the ventilation pipe 9 and introduces the oxygen under the driving of the air pump 10; whether the communication between the vent pipe 9 and the oxygen interface 100 is controlled by the second control valve 82 or not can rapidly introduce the oxygen in the oxygen storage tank 11 into the closed space formed by the mask body 1 and the face of the patient in the exchange process of the exhalation and the inhalation of the patient.

In one embodiment of the present application, as shown in fig. 3 and 4, the upper end of the sliding chamber 210 is connected to the air pump 10 through a communication pipe 7. Thereby when the patient breathes in, air pump 10 can start according to respiration sensor 4's detected signal to can aspirate slide chamber 210 through communicating pipe 7, so that the atmospheric pressure in the slide chamber 210 is reduced, and then the both ends of connecting rope 3 slide upwards along slide chamber 210 under the effect of negative pressure and tighten up in order to realize connecting rope 3. When the patient exhales, the connecting rope 3 needs to be loosened, so that a gap is formed between the mask body 1 and the face of the patient. And the specific loosening mode of the connecting rope 3 can be directly inflated into the sliding cavity 210 by the air pump 10, so that the internal air pressure of the sliding cavity 210 is increased, and the end of the connecting rope 3 slides downwards along the sliding cavity 210 to loosen the connecting rope 3. The loosening of the connecting rope 3 can also be achieved by the following mechanical construction.

It will be appreciated that the upper side of the sliding chamber 210 is in the direction of the outside of the mask body 1, and conversely the lower side of the sliding chamber 210.

In this embodiment, as shown in fig. 3, a piston 6 and a spring 5 are installed in the sliding cavity 210, the piston 6 is in sliding sealing fit with the side wall of the sliding cavity 210, and the bottom end of the piston 6 is connected with the end of the connecting rope 3. One end of the spring 5 abuts against the upper end of the piston 6, and the other end of the spring 5 abuts against the top of the sliding chamber 210. Therefore, when a patient inhales, the piston 6 can drive the end of the connecting rope 3 to slide upwards along the side wall of the sliding cavity 210 under the driving of negative pressure, and then the connecting rope 3 is driven to tighten and compress the spring 5. And when the patient exhales, the piston 6 can drive the end of the connecting rope 3 to slide downwards along the side wall of the sliding cavity 210 under the driving of the reset elastic force of the spring 5, so as to drive the connecting rope 3 to be loosened.

In this embodiment, as shown in fig. 4, the connection pipe 7 and the air pump 10 are connected by a first control valve 81, and the first control valve 81 is electrically connected to the respiration sensor 4. Therefore, when the patient inhales, the first control valve 81 can communicate the communication pipe 7 with the air pump 10 according to the detection signal of the respiration sensor 4, so that the sliding chamber 210 generates negative pressure under the driving of the air pump 10 to drive the connecting rope 3 to tighten. When the patient exhales, the first control valve 81 can communicate the communicating pipe 7 with the outside according to the detection signal of the respiration sensor 4, and further balance the sliding chamber 210 with the atmospheric pressure, so that the piston 6 can be reset under the elastic force of the spring 5.

In the present embodiment, as shown in fig. 1 to 3, a communication chamber 200 is provided inside the elastic pad 2, and one end of the communication chamber 200 is provided with a communication port 22. Communication pipe 7 is installed in communication chamber 200, and one end of communication pipe 7 communicates with slide chamber 210, and the other end of communication pipe 7 passes through communication port 22 and is connected to air pump 10. Communication pipe 7 can thereby be concentrated in elastic pad 2 to avoid scattering of communication pipe 7.
