Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is an exploded view of the present invention.
Wherein: 1. the mask comprises a mask body, 2 parts of a pressure release valve, 21 parts of a spring, 22 parts of a sealing ring, 23 parts of a top plate, 24 parts of a valve seat and 3 parts of a three-way pipe.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
A portable general breathing mask special for a life support system suitable for a high and cold environment is structurally shown in figures 1 and 2 and comprises a mask body 1, wherein a ventilation interface is arranged on the mask body corresponding to the position of an oral cavity, and an oxygen tube is assembled on the ventilation interface; a pressure relief opening is arranged on the mask body corresponding to the position of the nostril at the oblique upper part, and a pressure relief valve 2 is assembled in the pressure relief opening.
In the invention, the pressure release valve 2 is used for automatically opening to release pressure when the air pressure in the mask body is higher so as to ensure that the air pressure in the mask body is normal. The pressure release valve 2 comprises a valve seat 24, a spring 21 and a top plate 23, the valve seat 24 is of a cylindrical structure, the field opening end of the valve seat is in threaded fit with the pressure release opening, the spring 21 is axially and fixedly arranged in the inner cavity of the valve seat, the inner end of the spring is fixedly connected with the sealing end face of the inner cavity of the valve seat, the outer end of the spring is fixedly connected with the top plate, and the top plate is used for sealing the pressure release opening when the air pressure in the mask body is normal; the side edge of the open end part of the valve seat on the inner side of the top plate is provided with a plurality of vent holes for communicating the mask body with the outside when the air pressure in the mask body is ultrahigh, so that the inside and the outside of the mask body are kept smooth, the breathing requirement of a patient is met, and the suffocation condition is prevented.
In order to ensure that a patient can safely and stably inhale oxygen in a normal state, the pressure release valve is in a closed state, and therefore, a sealing groove is formed in the outer circumferential end face of the top plate 23, and a sealing ring 22 is embedded in the sealing groove. When the air pressure in the mask body is normal, the outer end face of the sealing ring is matched with the inner end face of the pressure relief port to seal the pressure relief port.
When the pressure relief valve is installed, the sealing ring is firstly sleeved in the sealing groove corresponding to the top plate, then the spring 21 is pressed into the valve seat 24, the top plate 23 sleeved with the sealing ring 22 is pressed into the valve seat 24 to prop against the pressure relief valve spring 21, sealing of the pressure relief valve is achieved, and then the assembled valve seat 24 is assembled into the pressure relief port in the mask body.
The patient may have weak consciousness in the treatment process, and if the air pressure in the mask body exceeds the standard, the patient can be reminded of treating personnel to treat the patient in time in other modes. The gas pressure sensor is used for detecting the gas pressure in the inner cavity of the mask body, the output end of the gas pressure sensor is connected with the wireless communication module, the wireless communication module is used for sending signals to the control unit of the portable universal life support system in a wireless mode, and the output end of the control unit is connected with the alarm; when the air pressure exceeds the limit, the control unit can control the alarm to give out audible and visual alarm.
In order to facilitate the use of a patient and avoid the collection of exhaled air in the mask body, the mask body is provided with a three-way switching valve at a ventilation interface, one end of the three-way switching valve is assembled with the ventilation interface, a second port is connected with an oxygen catheter, a third port is communicated with the outside, and the three-way switching valve can realize the switching of air inlet and air outlet of the mask body under the control of the breathing module. The first port communicates with the second port when the patient inhales to provide oxygen to the patient; when the patient exhales, the first port is communicated with the third port, and the gas exhaled by the patient is discharged to the outside.
Because the oxygen mask is usually used for rescuing and treating patients in a severe outdoor environment, when the external temperature is lower, the temperature of oxygen provided for the patients is also lower, and the discomfort of the patients is easily caused; the controlled end of the heating wire is connected with the control unit of the portable universal life support system through a switch, the input end of the control unit is connected with the output end of the temperature sensor, and the control unit is used for ensuring that oxygen delivered to a patient is in a proper constant temperature state, so that good treatment conditions are provided for the patient.
When the portable universal life support system is used, when a breathing module of the portable universal life support system works normally, a patient breathes normally, the pressure in the mask body 1 is smaller than the calibrated pressure of the pressure release valve, and the pressure release valve does not work. When breathing the module and becoming invalid, three-way switching valve stop work, can't be with the gaseous discharge face guard body 1 of patient exhalation, the patient will have the danger of suffocation, 1 internal pressure of face guard body will rise gradually, when 1 internal pressure of face guard body is greater than the pressure that the relief valve was markd, the top piece 23 will be withstood to the inside pressure of face guard body 1, with it to pushing away to vent hole department, 1 inside air vent and the atmosphere intercommunication of passing through of face guard body this moment, discharge the air of 1 inside of face guard body, reduce the pressure of 1 inside of face guard body, guarantee that the patient can normally breathe, reach the purpose of preventing suffocation.
In the oxygen conveying process, the temperature sensor monitors the temperature value of oxygen fed into the mask body in real time, and when the temperature value is lower than a set value, the control unit controls the heating wire to heat the oxygen in the oxygen conveying pipe through the switch, so that a patient is guaranteed to obtain oxygen with proper temperature.
