Description

Technical Field

[0001] The utility model relates to a respirator, in particular to a respirator for outpatient use, belonging to the technical field of respirators. Background Art

[0002] A ventilator is a device that can replace, control or change a person's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce respiratory work consumption, and save heart reserve capacity. A ventilator must have four basic functions, namely, inflating the lungs, converting inhalation to exhalation, expelling alveolar gas, and converting exhalation to inhalation, in sequence. Usually, a simple ventilator is used to assist patient treatment in outpatient treatment.

[0003] However, the connecting tube of the traditional simple ventilator is directly plugged into the exhalation valve or connected by a thread. When the direct plug-in connection method is used, the medical staff presses the mask and the connecting tube is easy to slip off the bottom end of the exhalation valve, so it needs to be re-plugged, affecting the medical effect. When the threaded connection method is used, it is more troublesome to replace the connector and the mask, which affects the replacement of the mask. Utility Model Content

[0026] As a technical optimization solution of the present invention, the four fixing bars 301 and the four buckles 304 are arranged in a circular array, and the four fixing bars 301 and the four buckles 304 are arranged alternately; the interior of the exhalation valve 201 is slidably connected to a duckbill one-way valve 204, and the bottom end of the exhalation valve 201 is provided with an air hole 205; the gas exhaled by the patient is discharged through the duckbill one-way valve 204, and oxygen is delivered to the patient's mouth and nose at the same time.

[0027] As a technical optimization solution of the present invention, one side of the exhalation valve 201 is fixedly connected to a branch pipe 206, and a safety valve 207 is provided on the branch pipe 206. The end of the branch pipe 206 is threadedly connected to an air bag 208, and an air intake valve 209 is installed on the air bag 208. The air intake valve 209 is fixedly connected to an oxygen tube 211, and the air intake valve 209 is provided with an air storage valve 210; two grooves 6 are symmetrically provided on the mask 1, the cross-section of the connecting sleeve 203 is an "I"-shaped structure, and the bottom end cross-section of the connecting sleeve 203 is a trapezoidal structure; the connecting sleeve 203 is made of elastic rubber material, the top cross-section of the buckle 304 is a trapezoidal structure, and the buckle 304 is elastic and assists the patient's breathing through the breathing structure 2.

[0028] As a technical optimization solution of the present invention, a quick-release structure 4 is provided on the mounting ring 303, and the quick-release structure 4 includes a placement ring 401. The mounting ring 303 is fixedly connected to the placement ring 401, and the mounting ring 303 is slidably connected to a quick-release ring 402, and the quick-release ring 402 is slidably connected to the placement ring 401; the quick-release ring 402 is fixedly connected to the connecting rod 403, the cross-section of the placement ring 401 is a U-shaped structure, and the cross-section of the connecting rod 403 is an L-shaped structure; the connecting tube 202 and the exhalation valve 201 are quickly disassembled through the quick-release structure 4.

A sealing groove 501 is provided on the inner wall of the connecting tube 202, and a sealing ring 502 is provided inside the sealing groove 501. The sealing ring 502 is slidingly connected to the exhalation valve 201; a sealing sleeve 503 is fixedly connected to the bottom end of the exhalation valve 201, and the sealing sleeve 503 is slidingly connected to the connecting tube 202. The sealing sleeve 503 conflicts with the sealing ring 502, and the sealing structure 5 improves the sealing between the connecting tube 202 and the exhalation valve 201.

[0030] When the utility model is used, when assisting the patient in breathing, first check the safety valve 207, then hold the mask 1 through the groove 6, buckle the mask 1 tightly around the patient's mouth and nose, connect the oxygen tube 211 to the oxygen supply equipment, and when assisting the patient to inhale, press the air bag 208, and positive pressure is generated inside the air bag 208, the duckbill one-way valve 204 opens, and the air inlet valve 209 closes. At the same time, the duckbill one-way valve 204 moves downward to block the air hole 205, and the gas enters the human body. When exhaling, release the air bag 208. The airbag 208 generates negative pressure, the duckbill one-way valve 204 closes and rises at the same time, no longer blocking the air hole 205, the air inlet valve 209 opens, the gas enters the airbag 208, and the patient's exhaled gas is discharged from the air hole 205. At the same time, the excess gas can be stored by connecting the air storage bag to the air storage valve 210. When it is necessary to connect the connecting tube 202 and the exhalation valve 201, the bottom end of the exhalation valve 201 is inserted into the interior of the connecting tube 202. At the same time, due to the buckle 30 The top cross-section of the four buckles 304 is a trapezoidal structure, and the buckles 304 are elastic, so the tops of the four buckles 304 will shrink first. When the four buckles 304 pass over the fixing ring 302, the buckles 304 are elastically reset and stuck on the fixing ring 302, thereby preventing the connecting tube 202 from slipping. The arrangement of the sealing ring 502, the sealing groove 501 and the sealing sleeve 503 improves the sealing between the connecting tube 202 and the exhalation valve 201. When it is necessary to quickly disassemble the connecting tube 202 and the exhalation valve 201, When the exhalation valve 201 is opened, the connecting rod 403 can be slid upward, and the upward sliding of the connecting rod 403 drives the quick-release ring 402 to slide upward, and the quick-release ring 402 contacts the four buckles 304 upward, so that the buckles 304 are no longer engaged with the fixing ring 302, and then the connecting tube 202 can be unplugged from the exhalation valve 201. At the same time, the bottom end of the connecting tube 202 is fixedly connected to the elastic connecting sleeve 203. The cross-section of the bottom end of the connecting sleeve 203 is trapezoidal, which is convenient for connecting the connecting sleeve 203 to the mask 1 and convenient for subsequent replacement of the mask.
