Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a portable oxygen respirator. Background Art

[0002] Oxygen is a gas on which humans rely for survival. People need to inhale oxygen when relieving symptoms such as palpitation, chest tightness, shortness of breath, and dizziness caused by hypoxia due to various reasons. For example, in a high-altitude environment, the oxygen in the air is relatively thin, and people may experience altitude sickness. At this time, it is necessary to inhale oxygen in time to relieve discomfort symptoms. At the same time, some people also need to inhale oxygen in time during disease treatment. The portable oxygen respirator is very suitable for daily use and emergency treatment due to its small size, large capacity, and convenient carrying, so it has been widely used. However, the traditional pressing-type oxygen respirator cannot view the pressure value in the bottle in real time, so that it is impossible to replace a new portable oxygen respirator or inflate the portable oxygen respirator in time, which may delay the use, and the pressing-type oxygen respirator is inconvenient to adjust the flow rate, affecting the use experience. Summary of the Utility Model

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a portable oxygen respirator with pressure display and flow rate adjustment.

[0004] To achieve the above object, the utility model provides the following technical solutions:

Embodiment 1

[0021] The present invention provides an embodiment, as Figures 1 - 3 shown, a portable oxygen respirator, comprising an oxygen cylinder 1 and a control cover 2. An oxygen pipeline 3 is arranged inside the control cover. An air outlet pipe 4 is arranged at the upper end of the side surface of the control cover. The air outlet pipe 4 is connected to the oxygen pipeline 3. The oxygen cylinder 1 and the control cover 2 are connected by threads. After the control cover is tightened, the air outlet of the oxygen cylinder is connected to the oxygen pipeline 3.

[0022] A push switch 5, a pressure sensor 7, a pressure display device 8 and a flow regulator 6 are arranged inside the control cover.

[0023] The pressure sensor 7 is arranged at one end of the oxygen pipeline 3 far from the air outlet pipe 4 (i.e., the end close to the air outlet of the oxygen cylinder). The pressure display device 8 includes a controller 801, a battery 802, a USB charging port 803, a display screen 804 and a power switch 805. The pressure sensor 7, the battery 802, the USB charging port 803, the display screen 804 and the power switch 805 are all electrically connected to the controller 801. The USB charging port 803, the display screen 804 and the power switch 805 are all embedded in the side surface of the control cover 2. The display screen 804 is located below the air outlet pipe 4, and the USB charging port 803 and the power switch 805 are located between the display screen 804 and the air outlet pipe 4. In this embodiment, the battery 802 is a rechargeable lithium battery, and the lithium battery can be charged through the USB charging port 803. The power switch 805 can control the operation of the pressure display device 8. When the power switch 805 is turned on, the pressure sensor 7 sends the measured data to the controller 801, and the controller 801 displays the processed pressure value on the display screen 804.

[0024] The push switch 5 is connected to the oxygen pipeline 3 and is located between the pressure sensor 7 and the flow regulator 6. When the push switch 5 is closed, the oxygen pipeline 3 is in a cut-off state, and at this time, no oxygen flows out of the air outlet pipe 4 through the oxygen pipeline 3; when the push switch 5 is opened, the oxygen pipeline 3 is in an open state, and oxygen can flow out of the air outlet pipe 4 through the oxygen pipeline 3.

[0025] The flow regulator 6 is connected to the oxygen pipeline 3 and is close to one end of the air outlet pipe 4. When it is necessary to adjust the air output volume of the air outlet pipe 4, only the flow regulator needs to be adjusted. In this embodiment, a needle valve is adopted, and its adjustment accuracy is relatively high, and the air flow size flowing out of the air outlet pipe 4 can be adjusted more precisely.

[0026] The portable oxygen respirator of this embodiment has a function of reminding of excessive flow. The flow regulator 6 can adjust the size of the oxygen flow of the air outlet pipe. When the oxygen flow is excessive, the controller 801 receives the data measured by the pressure sensor 7, and after data processing and calculation, the obtained result is compared with the set threshold. When it exceeds the threshold, the controller controls the display screen to give a prompt to remind the user that the flow may be adjusted too large, so as to adjust the flow size in time and avoid waste of oxygen.

[0027] The control cover 2 of this embodiment further includes an explosion-proof screw 9, which is arranged at one end of the oxygen pipeline 3 far from the air outlet pipe 4 (i.e., the end close to the air outlet of the oxygen cylinder). The explosion-proof screw is used to prevent excessive air pressure. When the pressure exceeds its set value, the explosion-proof copper sheet will burst to release the excess pressure, thereby ensuring the safety of the operator.

[0028] The operation process of using the portable oxygen respirator of this embodiment is as follows: Before use, the power switch 805 can be turned on first to check the pressure value of the oxygen cylinder and determine whether it is necessary to replace or add a new portable respirator device; during use, connect the breathing mask 11 or nasal cannula to the air outlet pipe 4, press the pressing switch 5, the oxygen pipeline 3 is conducted, wear the breathing mask or nasal cannula, and rotate the flow regulator 6 as needed to control the size of the air output. During the use process, the pressure value displayed on the display screen can also be checked at any time. After the oxygen inhalation is completed, turn off the pressing switch 5, tighten the flow regulator 6, and turn off the power switch 805. Embodiment 2

[0029] Based on the structure of Embodiment 1, the controller 801 in the pressure display device 8 of this embodiment further includes a Bluetooth module. The portable oxygen respirator can be connected to the mobile phone APP through the Bluetooth module. Through the mobile phone APP, the pressure value of the oxygen cylinder can be viewed in real time, and the prompt threshold for excessive oxygen flow can also be set through the mobile phone APP. When the oxygen flow exceeds the threshold, the mobile phone APP synchronously displays a reminder of excessive flow, which is very convenient. Embodiment 3

[0030] As Figure 4 shown, based on the structure of Embodiment 1, the portable oxygen respirator of this embodiment further includes an inflation port 10, which is arranged at the bottom of the oxygen cylinder. When the oxygen in the bottle is insufficient, inflation can be carried out through the inflation port 10 to recycle the portable oxygen respirator and reduce the use cost. The inflation port 10 is made of stainless steel and is internally provided with a one-way valve to prevent gas leakage. When oxygen is filled into the bottle through the inflation port 10, the pressure value of the filled oxygen can be directly displayed through the display screen 804 to prevent over-inflation and cause danger.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
