Description

Technical Field

[0001] The utility model relates to the technical field of simple artificial respirators, in particular to a simple artificial respirator. Background Art

[0002] A simple respirator, also known as an artificial respirator or a pressurized oxygen bag, is a simple tool for artificial ventilation. Compared with mouth-to-mouth respiration, it has a higher oxygen concentration and is easier to operate. Especially when the patient is in critical condition and there is no time for tracheal intubation, a pressurized mask can be used to directly supply oxygen, so that the patient can get sufficient oxygen supply and improve tissue hypoxia.

[0003] The simple artificial respirator includes components such as a mask, a one-way valve, a pressure safety valve, a ball, an air inlet valve, an air bag, and an exhalation valve. When in use, the user holds the mask against the patient's mouth and nose with one hand, and holds the air bag with the other hand, and squeezes the air bag with the hand holding the air bag, thereby squeezing and pushing the oxygen in the air bag into the patient's body. When using the simple artificial respirator, it is necessary to control the ventilation volume by controlling the degree of squeezing the air bag. When the ventilation volume is low, it is difficult to effectively assist the patient's breathing, and when the ventilation volume is high, it is easy to cause barotrauma. When using the existing simple artificial respirator, the degree of squeezing of the air bag is difficult to control, and the operator's proficiency is required to be high, and it is not convenient to use.

DETAILED DESCRIPTION

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-3 As shown, a simple artificial respirator includes an air inlet pipe 1, an air inlet valve 2, a balloon 3, a pressure limiting valve 4, a breathing valve 5 and a mask 6 which are connected in sequence. The balloon 3 has an air inlet end and an air outlet end. The outer surface of the balloon 3 is provided with a limiting ring 7 close to one end of the air inlet end. The air outlet end of the balloon 3 is symmetrically provided with mounting blocks 8. Both mounting blocks 8 are provided with rocker arms 9. The two rocker arms 9 are connected by a cross bar 10. The apparatus also includes an extrusion plate 11. The upper surface of the extrusion plate 11 is symmetrically provided with connecting plates 12. The connecting plates 12 and the extrusion plate 11 are detachably connected.

[0018] The function and structure of the simple artificial respirator are the same as those commonly seen on the market. The utility model only improves the structure of the balloon 3. If there are parts that are not mentioned but are necessary for the simple artificial respirator, it does not affect the sufficiency of the disclosure of the utility model.

[0019] The limiting ring 7 is installed on the outer surface of the balloon 3. When using the device, the left forearm is passed through the limiting ring 7, and then the left hand is used to control the breathing valve 5 and the mask 6 at the same time, and the mask 6 is attached to the patient's mouth and nose. After the mask 6 is attached, the right hand holds the cross bar 10, and then the cross bar 10 is used to control the two rocker arms 9 to swing. The swing of the two rocker arms 9 drives the connecting plate 12 and the squeezing plate 11 to move, and the gas in the balloon 3 is transported into the patient's body through the squeezing of the squeezing plate 11 and the balloon 3.

[0020] When the movement of the rocker arm 9 is controlled by the cross bar 10, until the squeezing plate 11 can no longer move downward, that is, the rocker arm 9 can no longer rotate, the single delivery of gas within the rated value range into the patient's body is completed. By controlling the area of ​​the squeezing plate 11, the single delivery of gas within the rated value range into the patient's body can be controlled. The larger the area of ​​the squeezing plate 11, the larger the area of ​​the outer surface of the balloon 3. When the squeezing plate 11 is fully squeezed, the more volume of gas is delivered. When the area of ​​the squeezing plate 11 is smaller, the area of ​​the outer surface of the balloon 3 is smaller. When the squeezing plate 11 is fully squeezed, the volume of gas delivered is relatively reduced. By adjusting the area of ​​the squeezing plate 11 to match it with the volume of the balloon 3, the volume of gas delivered each time meets the requirements. This standard is applicable to adults.

[0021] Furthermore, a protrusion 13 is provided on the upper end of the connecting plate 12, a slot is provided inside the rocker arm 9, and threaded holes are provided on the protrusion 13 and the rocker arm 9. The rocker arm 9 and the protrusion 13 are connected by screws 14. The protrusion 13 on the connecting plate 12 is inserted into the slot, and then the protrusion 13 and the rocker arm 9 are connected and fixed together by screws 14, so that the connecting plate 12 and the rocker arm 9 are installed and fixed. Two installation positions for installing the connecting plate 12 are provided on a single rocker arm 9, that is, a single rocker arm 9 has two slots, and each slot has a threaded hole, one of which has a larger exhaust volume and is suitable for adults, and the other has a smaller exhaust volume and is suitable for children. When facing children, it is necessary not only to adjust the position of the extrusion plate 11, but also to replace the mask 6 according to actual conditions, so that the mask 6 can be better attached to the mouth and nose of the child.

[0022] Further, the connecting plate 12 is bendable, and an upper clamping plate 15 and a lower clamping plate 16 are provided on one side of the upper end of the connecting plate 12, and the swing rod 9 is located between the upper clamping plate 15 and the lower clamping plate 16. A side rod 17 is provided on one side of the connecting plate 12 and is located between the upper clamping plate 15 and the lower clamping plate 16. A through hole for the side rod 17 to pass through is opened on the outer surface of the swing rod 9. When installing, first squeeze the two connecting plates 12, the two connecting plates 12 are close to each other, and then the through holes on the two connecting plates 12 are simultaneously aligned with the through holes on the two swing rods 9, and then the two connecting plates 12 are loosened, and the two swing rods 9 are respectively entered into the two connecting plates. Between the upper clamping plate 15 and the lower clamping plate 16 on the connecting plate 12, the installation of the connecting plate 12 and the extrusion plate 11 is completed. Two installation positions for installing the connecting plate 12 are set on the single rocker arm 9, that is, the single rocker arm 9 has two through holes. When installed in one of the positions, the exhaust volume of the balloon 3 is large, which is suitable for adults. In the other installation position, the exhaust volume of the balloon 3 is small, which is suitable for children. When facing the children, not only the position of the extrusion plate 11 needs to be adjusted, but also the mask 6 needs to be replaced according to the actual situation so that the mask 6 can be better attached to the mouth and nose of the child.

[0023] Furthermore, an isolation plate 18 is provided on the outer surface of the balloon 3 , and the isolation plate 18 is located between the limiting ring 7 and the balloon 3 . The isolation plate 18 is a hard plastic plate, which reduces the impact of the operator's arm squeezing the balloon 3 .

[0024] The device can control the squeezing plate 11 to squeeze the balloon 3 through the cross bar 10 and the rocker arm 9, so that after completing a full squeezing, the squeezing plate 11 can deliver a volume of gas within the rated value range into the patient's body, ensuring the safety of gas delivery, and the operator does not need to personally control the squeezing force of the balloon 3, only needs to complete a full squeezing, thereby reducing the difficulty of operation and improving the convenience and safety of use.
