[0002] At present, the exhaust devices used for infusion are mostly used in wards, and the venue is on the ground, and the impact of the environment does not need to be considered during the operation. However, in the process of transporting patients by airplane, when performing infusion operations on board, affected by the environment and the venue, the use of traditional curved trays for drainage has certain limitations, such as air turbulence, small space, and the inability to push the treatment cart back and forth. The liquid in the curved tray is easy to spill, causing the liquid to flow into the cabin, affecting the correct operation of the aircraft. Therefore, on this basis, an airborne infusion exhaust device is designed.

The device box is designed with a device box base and a device box cover, which are fixed by a connecting hinge and act on opening and closing. Two rollers in the device box are designed to be fixed on two rollers in the device box to play a role of mutual squeezing and rolling. A stainless steel clip is designed to be fixed on the work clothes pocket, and the base magnet bar and the box cover magnet bar are parallel to each other, which plays a role in the closed state of the device box, making it easy to fix and use. The upper pipe slot and the lower pipe slot are used to provide a fixed space for the infusion pipe. It has the characteristics of simple operation, repeated use, and low cost. It has the functions of convenient carrying and simple operation, and can achieve the effect of rapid exhaust to ensure the safety of patient infusion.

[0004] However, there are problems such as the infusion and exhaust device shaking and falling due to aircraft turbulence, affecting the infusion, and the liquid easily spilling, causing the liquid to flow into the cabin, affecting the correct operation of the aircraft, and the shaking of the infusion and exhaust device causing backflow. Therefore, we propose a roadbed compaction device that is easy to adjust the orientation to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: an air-use infusion exhaust device, including a stretcher support 1, a placement seat 2, a fixing plate 3, a Velcro 4, a device body 5, a bottle mouth 6, a sealing ring 7, a bottle cap 8, a rotating plate 9, a fan-shaped plate 10, a card plate 11, a card slot 12, a stopper 13, a regulating valve 14, a regulating plate 15, a rubber stopper 16, an infusion tube 17 and a stop valve 18, such as Figure 1 and Figure 3 As shown, a fixing plate 3 is installed on the surface of the stretcher support 1, and a placement seat 2 is installed on the right side of the fixing plate 3. When the patient needs to be infused on the plane, the patient lies on the stretcher, and the infusion exhaust device is placed in the placement seat 2. The placement seat 2 supports the infusion exhaust device. A screw is installed on the front surface of the fixing plate 3. Unscrew the locking nut and the screw, pull the placement seat 2 up and down, move the placement seat 2 to a suitable height, and then align the screw with the fixing plate 3, tighten the screw and the locking nut, fix the fixing plate 3 and the placement seat 2, and adjust the height position of the infusion exhaust device conveniently.

[0025] The surface of the stretcher support 1 is installed with Velcro 4, which can be bonded to each other, and play a role in fastening and stabilizing the device body 5 to prevent the device body 5 from tipping over and falling due to the turbulence of the aircraft. The upper end of the device body 5 is threadedly installed with a bottle mouth 6, and the upper surface of the device body 5 is installed with a sealing ring 7. The bottle mouth 6 is aligned with the device body 5, and the bottle mouth 6 is tightened to facilitate the installation of the bottle mouth 6. The sealing ring 7 increases the sealing of the bottle mouth 6 and the device body 5 to prevent liquid from leaking. The upper end of the bottle mouth 6 is threadedly installed with a bottle cap 8. The bottle cap 8 is unscrewed to facilitate the input of liquid. The bottle mouth 6 is designed to be funnel-shaped, which is convenient for liquid to flow in. At the same time, it is convenient to disassemble the bottle mouth 6 and the device body 5, and it is convenient to disassemble, wash and disinfect;

[0026] The liquid flows into the device body 5, and the left and right sides of the device body 5 are rotatably installed with rotating plates 9 through the rotating shaft and the return spring. The inner side of the rotating plate 9 is installed with a fan-shaped plate 10. The lower end of the left fan-shaped plate 10 is provided with a card slot 12, and the left end of the right fan-shaped plate 10 is installed with a card plate 11. When the liquid enters the device body 5, it impacts the fan-shaped plate 10. The fan-shaped plate 10 rotates downward and opens under the impact of the liquid, and the rotating plate 9, the rotating shaft and the return spring rotate accordingly, so that the liquid can be transported;

[0027] like Figure 2 and Figure 4 As shown, when the aircraft turbulence causes liquid backflow, the rotating plate 9, the rotating shaft and the reset spring work together to drive the fan-shaped plate 10 to return to its original position upward, and the front and rear side walls inside the device body 5 are both installed with stoppers 13, which block the fan-shaped plate 10 to prevent the fan-shaped plate 10 from continuing to rotate upward. The clamping plate 11 on the fan-shaped plate 10 is clamped and installed in the clamping groove 12, and the fan-shaped plate 10 blocks the liquid backflow in the device body 5. The clamping plate 11 and the clamping groove 12 play a sealing role to prevent the liquid from backflowing from the gap;

[0028] The right arm of the device body 5 is rotatably mounted with a regulating valve 14, and the left end of the regulating valve 14 is mounted with an adjusting plate 15. When the regulating valve 14 is rotated, the regulating valve 14 drives the adjusting plate 15 to rotate, thereby facilitating the adjustment of the flow rate of the liquid to meet the infusion needs of different patients.

[0029] After the liquid is input into the device body 5, an insertion needle is installed at the upper end of the infusion tube 17, and a rubber plug 16 is installed at the bottom end of the device body 5. The insertion needle at the upper end of the infusion tube 17 is inserted into the rubber plug 16, and the insertion needle enters the device body 5. A stop valve 18 is installed on the surface of the infusion tube 17. The roller inside the sliding stop valve 18 is convenient for opening and closing the infusion tube 17 and adjusting the flow rate of the infusion tube 17 at the same time. After the insertion needle enters the device body 5, the roller inside the stop valve 18 is slowly slid to open the infusion tube 17, and the liquid flows into the infusion tube 17, which is convenient for discharging the gas in the infusion tube 17. When the vascular needle at the end of the infusion tube 17 drips liquid, the stop valve 18 is closed in time to prevent waste of liquid discharge. After the vascular needle is inserted into the patient's blood vessel, the stop valve 18 is opened to facilitate infusion to the patient.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
