[0031] In actual use of an existing simple respirator, when the simple respirator is squeezed, since the oxygen flow rate required by patients of different age groups is different, it is necessary to measure according to the patient's specific inhaled content. If the intake air volume cannot be measured, it may be impossible to understand the changes in the patient's breathing condition in time. Therefore, this problem is solved by measuring the patient's gas inhalation volume.

[0032] like Figures 1 to 4 The utility model provides a simple respirator auxiliary metering device.

[0033] Specifically, by Figure 1-5 A simple ventilator auxiliary metering device is provided, comprising a balloon 1 and a metering component 2, wherein the metering component 2 limits the expansion volume of the balloon 1 while transmitting gas in the balloon 1, the metering component 2 comprises an air pipeline 201 plugged into the balloon 1, an end of the air pipeline 201 away from the balloon 1 is connected to the air bag 202, an outer wall of the air pipeline 201 is connected to a connecting block 203, the connecting block 203 is threadedly connected to two bolts 204, an outer wall of the bolt 204 is threadedly connected to an arc-shaped measuring rod 205, the balloon 1 is located between the two arc-shaped measuring rods 205, an outer wall of the connecting block 203 is integrally formed with a scale, and a pointer is provided on the top of one of the arc-shaped measuring rods 205.

[0034] In the utility model, an oxygen bag is put on the outer wall of the oxygen inlet tube 3, and oxygen is allowed to enter the inside of the airbag 202 from the oxygen inlet tube 3 by squeezing the airbag 202. When the airbag 202 is full of oxygen, the airbag 202 is squeezed to allow oxygen to enter the inside of the balloon 1 through the gas pipeline 201, and oxygen is transmitted to the balloon 1. The balloon 1 expands when receiving oxygen, and the expanded balloon 1 resists the arc-shaped measuring rods 205 on both sides, driving the two arc-shaped measuring rods 205 to move, so that one end of one of the arc-shaped measuring rods 205 with a pointer rotates around the outer wall of the bolt 204 with the bolt 204 as the center point;

[0035] By aligning the pointer at the top of the arc-shaped measuring rod 205 with a certain scale value at the top of the connecting block 203, medical staff can conveniently measure the expansion size of the balloon 1 and the oxygen content in the balloon 1 by viewing the scale value, and the connecting block 203 supports and fixes the bolt 204 and the arc-shaped measuring rod 205. The expansion range and gas volume of the balloon 1 are measured by moving the arc-shaped measuring rod 205 and the pointer position, which facilitates the measurement of changes in the patient's breathing condition.

[0036] Furthermore, as a specific implementation of the present invention, the present invention provides a simple respirator auxiliary metering device.

[0037] Specifically, Figure 1-3 It is shown that a transmission tube 12 is connected to the side of the balloon 1 away from the gas pipeline 201 , a mask 9 is provided on one side of the balloon 1 , and the mask 9 is connected to a connecting tube 8 corresponding to the transmission tube 12 .

[0038] In the utility model, when the outer wall of the balloon 1 hits the inner wall of the arc-shaped measuring rod 205, it means that the gas in the balloon 1 has reached the metering value, and then the balloon 1 is squeezed to transmit the oxygen into the interior of the connecting tube 8 through the transmission tube 12, and then the oxygen is transmitted into the mask 9 by the connecting tube 8. The mask 9 is placed on the patient's mouth and nose, and the patient can inhale the oxygen transmitted in the mask 9.

[0039] Furthermore, as another specific implementation of the present invention, the present invention provides a simple respirator auxiliary metering device.

[0040] Specifically, Figure 1-2 It is shown that an air inlet valve 4 is installed at the bottom of the airbag 202, and the air inlet valve 4 is connected to the oxygen inlet pipe 3. An air outlet valve 5 is installed at the top of the airbag 202, and one end of the gas pipeline 201 is plugged into the air outlet valve 5.

[0041] In the utility model, the oxygen bag is put on the outer wall of the oxygen inlet tube 3, so that oxygen can enter the interior of the airbag 202 from the oxygen inlet tube 3 by squeezing the airbag 202. The air inlet valve 4 is used to control the opening and closing of the oxygen inlet tube 3, so that the oxygen inlet tube 3 is in a closed state when the airbag 202 is squeezed, so that oxygen can directly enter the gas pipeline 201 and be transmitted to the interior of the ball bag 1 when the airbag 202 is squeezed. The air outlet valve 5 is also used to control the opening and closing of the gas pipeline 201, so that the oxygen will not be transmitted back to the gas pipeline 201 when the ball bag 1 is squeezed.

[0042] Furthermore, as another specific implementation of the present invention, the present invention provides a simple respirator auxiliary metering device.

[0043] Specifically, Figure 1-5 It is shown that the connecting block 203 is provided with two square grooves, the bolt 204 is located between the connecting block 203 and the square groove, one end of the arc-shaped measuring rod 205 is located inside the square groove, and the curvature of the arc-shaped measuring rod 205 is adapted to the shape of the balloon 1.

[0044] In the utility model, the square groove provides a rotatable area for the arc-shaped measuring rod 205, so that one end of the arc-shaped measuring rod 205 will not collide with the outer wall of the connecting block 203 and affect the rotation range when rotating along the outer wall of the bolt 204. The curvature of the arc-shaped measuring rod 205 is adapted to the shape of the balloon 1, so that the balloon 1 can maintain an appropriate shape and volume when expanded.

[0045] Furthermore, as another specific implementation of the present invention, the present invention provides a simple respirator auxiliary metering device.

[0046] Specifically, Figure 2-5 It is given that the outer wall of the bolt 204 is threadedly connected with a nut 6, and the nut 6 is located at the bottom of the connecting block 203. The outer wall of the bolt 204 is sleeved with an anti-skid gasket 14, and the anti-skid gasket 14 is tightly attached to the bottom of the connecting block 203. The anti-skid gasket 14 is located between the nut 6 and the connecting block 203 and is tightly attached to the outer wall of the nut 6.

[0047] In the utility model, the position of the bolt 204 is fixed by screwing the nut 6, so as to prevent the connection between the bolt 204 and the connecting block 203 from being too loose, so as to prevent the loosening of the bolt 204 from causing the arc-shaped measuring rod 205 to slide before being contacted by the expansion of the balloon 1, resulting in inaccurate positions of the pointer and the scale. The anti-slip gasket 14 increases the friction between the nut 6 and the bolt 204, preventing the nut 6 from sliding off the outer wall of the bolt 204.

[0048] Furthermore, as another specific implementation of the present invention, the present invention provides a simple respirator auxiliary metering device.

[0049] Specifically, Figure 1 and 3 It is shown that the transmission tube 12 is connected with a flow meter 13, one end of the balloon 1 is connected with a safety valve 15, the transmission tube 12 is connected to the safety valve 15, a sleeve 7 is sleeved between the transmission tube 12 and the connecting tube 8, and one end of the flow meter 13 is located outside the transmission tube 12 and close to the safety valve 15.

[0050] In the utility model, the safety valve 15 can automatically open when the gas pressure in the balloon 1 is too high to release excess gas, thereby preventing the balloon 1 from rupturing or other accidents due to excessive pressure. When the oxygen in the balloon 1 is transmitted into the connecting tube 8 through the transmission tube 12, the transmission tube 12 is connected to the transmission port of the connecting tube 8 through the sleeve 7 to prevent oxygen leakage.

[0051] Furthermore, as another specific implementation of the present invention, the present invention provides a simple respirator auxiliary metering device.

[0052] Specifically, Figure 1 It is shown that a sealing pad 10 is connected to one side of the mask 9, a fixing belt 11 is connected to the outer wall of the mask 9, the sealing pad 10 is located between the fixing belt 11 and the mask 9, and the fixing belt 11 is made of polyester fiber.

[0053] In the utility model, the sealing pad 10 can effectively reduce the air leakage of the mask 9 and improve the sealing performance of the mask 9, thereby improving the use effect and safety of the respirator. The fixing belt 11 can be put on the patient's head to fix the mask 9 on the patient's face to prevent it from falling. The fixing belt 11 is made of polyester fiber. The polyester fiber material has high elasticity and recovery, can effectively fix the mask 9, and can withstand large pulling force, and is not easy to deform or break.

[0054] Working principle:

[0055] The oxygen bag is put on the outer wall of the oxygen inlet tube 3, and the oxygen enters the airbag 202 from the oxygen inlet tube 3 by squeezing the airbag 202. When the airbag 202 is full of oxygen, the airbag 202 is squeezed to allow the oxygen to enter the balloon 1 through the gas pipeline 201, and the oxygen is transmitted to the balloon 1. The balloon 1 expands due to the oxygen, and the expanded balloon 1 resists the arc-shaped measuring rods 205 on both sides, driving the two arc-shaped measuring rods 205 to move, so that the end of one of the arc-shaped measuring rods 205 with a pointer rotates around the outer wall of the bolt 204 with the bolt 204 as the center point;

[0056] By aligning the pointer at the top of the arc-shaped measuring rod 205 with a certain scale value at the top of the connecting block 203, medical staff can conveniently measure the expansion size of the balloon 1 and the oxygen content in the balloon 1 by viewing the scale value, and the connecting block 203 supports and fixes the bolt 204 and the arc-shaped measuring rod 205. The expansion range and gas volume of the balloon 1 are measured by moving the arc-shaped measuring rod 205 and the pointer position, which facilitates the measurement of changes in the patient's breathing condition.

[0057] When the outer wall of the balloon 1 hits the inner wall of the arc-shaped measuring rod 205, it means that the gas in the balloon 1 has reached the metering value. Then the balloon 1 is squeezed to allow the oxygen to be transmitted into the interior of the connecting tube 8 through the transmission tube 12. The connecting tube 8 then transmits the oxygen into the mask 9. The mask 9 is placed on the patient's mouth and nose, so that the patient can inhale the oxygen transmitted in the mask 9.

[0058] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
