Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an oxygen bag auxiliary pressurizing device. Background Art

[0002] An oxygen bag is a device used to provide oxygen supply in emergency situations. It is usually a bag filled with oxygen and can be used in first aid, high altitude oxygen depletion, fire, sudden accidents and other situations to help people get enough oxygen to maintain breathing and life activities. Oxygen bags are generally equipped with masks or pipes to facilitate users to inhale oxygen. In some special cases, oxygen bags can be life-saving tools.

[0003] When the pressure in the oxygen bag decreases, you can add pressure manually to facilitate the discharge of oxygen; or you can put the oxygen bag under the patient's head as a pillow and use the weight of the patient's head to discharge the oxygen. However, this operation is not very effective, because most oxygen bags are used during transportation, and medical staff need to press the oxygen bag while walking, which is inconvenient to operate, and uneven force will also cause discomfort to the patient, and the patient will be very unstable if he uses it as a pillow. Utility Model Content

[0004] The utility model aims to provide an oxygen bag auxiliary pressurizing device which can input oxygen at a uniform speed and avoid causing discomfort to patients.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] An oxygen bag auxiliary pressurizing device includes a shell, an adjusting plate is arranged inside the shell, an air bag is arranged on the outer surface of the adjusting plate, a mounting plate is installed on the top of the adjusting plate, a motor is installed on the lower surface of the mounting plate, and the end of the motor output shaft passes through the upper side of the mounting plate and is installed with a disc. A U-shaped plate is slidably mounted on the upper surface of the mounting plate, a limiting groove is provided on the U-shaped plate, a toggle rod is arranged on the upper surface of the disc, and the toggle rod is arranged in the limiting groove. An air cylinder is installed on the upper surface of the mounting plate, a piston rod is arranged inside the air cylinder, and the end of the piston rod is connected to the U-shaped plate. The outer surface of the air cylinder near its end is respectively connected to an air inlet pipe and an air outlet pipe, and the end of the air outlet pipe is connected to the air bag, and a one-way valve is arranged inside the air inlet pipe and the air outlet pipe.

[0007] It can be seen that after the oxygen bag is placed in the shell, the piston rod is driven to move by starting the motor, and then the airbag is continuously inflated to expand it, and the oxygen bag is squeezed, so as to achieve the purpose of evenly inputting oxygen and avoiding discomfort to the patient.

[0008] Furthermore, a limit rod is connected to the side of the adjustment plate facing away from the airbag, and the end of the limit rod passes through the outside of the shell. The side of the adjustment plate facing away from the airbag is rotatably connected to a first screw rod, and the end of the first screw rod passes through the outside of the shell and is threadedly connected thereto, and a first knob is installed on the end of the first screw rod.

[0009] Since the limit rod limits the adjustment plate, when the first screw is rotated, the adjustment plate can be driven to move forward and backward. According to the oxygen content in the oxygen bag, the position of the adjustment plate can be adjusted to make the airbag contact the oxygen bag. Then, under the inflation action of the gas cylinder, the airbag can be driven to expand and pressurize the oxygen bag.

[0010] Furthermore, a mounting groove is provided on the upper surface of the disc, a second screw is rotatably connected inside the mounting groove, a nut seat is installed on the outer surface of the second screw, and a toggle rod is installed on the upper surface of the nut seat, and a second knob is installed on the end of the second screw.

[0011] By rotating the second screw rod, the nut seat can be driven to move along its surface, and then the toggle rod can be driven to move. By changing the distance between the toggle rod and the center of the disk, the expansion and contraction amount of the piston rod can be changed when the disk rotates, thereby realizing the adjustment of the airbag inflation rate, and the extrusion speed of the oxygen bag can be adjusted according to actual conditions, and the application range is wide.

[0012] Furthermore, a U-shaped block is installed on the upper surface of the shell, a third screw rod passes through the interior of the U-shaped block and is threadedly connected, a pressing block is installed at the bottom of the third screw rod, and a third knob is installed on the top of the third screw rod.

[0013] By clamping the U-shaped block on the bed guardrail, the third screw is rotated to drive the pressing block to descend and press it on the bed guardrail. Therefore, the shell can be fixed on the bed during patient transfer, without occupying the bed space, and avoiding the situation where medical staff need to press the oxygen bag while walking, which is convenient to use.

[0014] Furthermore, a rubber pad is provided on the lower surface of the pressing block, and anti-slip grooves are provided on the surface of the rubber pad.

[0015] By providing the rubber pad and the anti-slip grooves, the friction between the pressing block and the bed guardrail can be increased, thereby improving the fixing effect.

[0016] Furthermore, the number of the limiting rods is four, and the four limiting rods are respectively arranged at the four corners of the adjustment plate.

[0017] By setting four limit rods, the stability of the adjustment plate can be improved, thereby driving the airbag to apply pressure to the oxygen bag in all directions. BRIEF DESCRIPTION OF THE DRAWINGS
