Description

Technical Field

[0001] The invention relates to the technical field of biomedicine, and in particular to a biomedical mobile oxygen vehicle. Background Art

[0002] In various biomedical work, the transportation of biological reagent bottles is a frequent and crucial task. The traditional method of transporting by hand by staff is inefficient. At the same time, some biological reagent bottles need to be stored under appropriate oxygen concentrations, which makes it difficult to ensure the safety of the reagents.

[0003] Existing oxygen cylinders need to be transported on a separate cart. If they need to be used in multiple locations within a short period of time and used in combination with other items, the oxygen cylinder cannot be transported while transporting other items. In addition, when transporting items that require oxygen supply, existing biomedical carts cannot directly supply oxygen to them with oxygen.

[0004] At the same time, in the biomedical environment, you will encounter oxygen cylinders of various specifications. Due to different biomedical needs and supply channels, the diameters of oxygen cylinders often vary. Traditional oxygen vehicles are helpless when facing oxygen cylinders of different diameters. They cannot effectively fix and transport them, and thus cannot ensure that they will not shake or fall during transportation.

[0005] Moreover, if the oxygen vehicle keeps moving when replacing the oxygen cylinder, it will not only cause the oxygen cylinder to collide with surrounding objects and cause danger, but also make it impossible to quickly replace the oxygen cylinder.

[0006] Therefore, a biomedical mobile oxygen vehicle is proposed. Summary of the invention

[0048] Furthermore, a connection port 29 is provided on the side wall of the medical oxygen vehicle 1, which is located on one side of the wheel 25, and a connection port 2 30 is provided on the side wall of the biological reagent box 4. The connection port 29 and the connection port 2 30 are interconnected, and an air duct is installed between the connection port 29 and the connection port 2 30, and the air duct can introduce the oxygen in the oxygen cylinder into the interior of the biological reagent box 4.

[0049] The above implementation works as follows:

[0050] The initialization steps are as follows:

[0051] The staff member leans sideways and holds the handle 2 to push the wheel 25 to roll, thereby realizing the movement of the medical oxygen cart 1. At the same time, the staff member pushes the medical oxygen cart 1 to the biological reagent bottle that needs to be transported for biomedical research. The staff member bends down to pull the biological reagent box 4 out of the inner cavity of the groove 3 and opens the door of the biological reagent box 4, places the biological reagent bottle that needs to be transported inside the biological reagent box 4, and closes the door of the biological reagent box 4 and puts the biological reagent box 4 into the groove 3. At the same time, the staff member inserts the airway tube into the connecting port 2 30 and passes it through the inside of the connecting port 1 29, and then the staff member pushes the medical oxygen cart 1 to the place where the oxygen cylinder is stored to replace or install the oxygen cylinder.

[0052] The working steps are as follows:

[0053] The adapter component works as follows:

[0054] In the cell culture link of biomedicine, the growth and proliferation of many cells have strict requirements on oxygen concentration, so it is necessary to install oxygen cylinders on the medical oxygen vehicle 1. When the staff installs the oxygen cylinders or replaces oxygen cylinders with different diameters, the staff manually rotates the threaded rod 8, so that the rotating block 2 9 slides on the threaded rod 8 in the direction close to the rotating block 1 7 through the continuous rotation of the threaded rod 8, so that the rotating block 2 9 drives the arc block 12 to move clockwise with the rotating ring 10 as a circle, so that the arc block 12 drives the rotating ring 10 to rotate on the fixed frame 6, and because the incomplete gear 13 is a clockwise arc motion, the incomplete gear 13 drives the rotating block 2 9 to move synchronously, and at the same time, the rotation of the rotating block 2 9 drives the threaded rod 8 and pushes the rotating block 1 7 to rotate clockwise with the connection between the rotating block 1 7 and the fixed frame 6 as the axis, thereby avoiding the situation where the staff twists the threaded rod 8 and it gets stuck;

[0055] When the rotating ring 10 rotates on the fixed frame 6 with the rotating ring 10 center as the axis, the rotating ring 10 drives the three fixed blocks 11 to move synchronously, so the three fixed blocks 11 also drive the incomplete gear 13 to rotate clockwise with its own center as the axis, so the incomplete gear 13 drives the three limit shells 14 to move synchronously, so that the three limit shells 14 rotate clockwise and push the three sliding rods 15, at this time, the three sliding rods 15 move in the direction away from the center of the incomplete gear 13 with the connection between the sliding rod 15 and the fixed frame 6 as the axial direction, and also push the limit shell 14 to rotate on the incomplete gear 13 along the movement direction of the incomplete gear 13, so that the three sliding rods 15 drive the rollers 16 on each of them to move away from the center of the incomplete gear 13, so that the three rollers 16 are at a distance of 1.5 meters from the center of the incomplete gear 13 The distance is getting farther and farther, and at the same time, the roller 16 moves in the gap between two adjacent fixed blocks 11 while moving away from the center of the incomplete gear 13. When the side wall of the sliding rod 15 hits the fixed block 11, the staff stops twisting the threaded rod 8. At the same time, as shown in the initialization step, the staff lifts the oxygen cylinder and passes it horizontally through the incomplete gear 13, the rotating ring 10, the fixed frame 6, and the center of the opening 5, so that the entire oxygen cylinder passes horizontally through the inside of the opening 5. When the bottom end of the oxygen cylinder is at the center of the incomplete gear 13, the staff no longer places the oxygen cylinder into the opening 5. The distance that the three rollers 16 move away from the center of the incomplete gear 13 is greater than the diameter of the oxygen cylinder. After the oxygen cylinder is inserted, the threaded rod 8 is rotated in the opposite direction so that the three rollers 16 are completely attached to the oxygen cylinder.

[0056] The setting of the adapter component can adapt to and fix oxygen cylinders of different diameters, and the three rollers 16 resist the outer wall of the oxygen cylinder to ensure that the oxygen cylinder will not shake or fall during the transportation of biological reagent bottles. At the same time, the three rollers 16 are set with rubber to reduce the vibration of the oxygen cylinder caused by road bumps.

[0057] The working steps of connecting components are as follows:

[0058] As mentioned above, when the incomplete gear 13 rotates clockwise, the incomplete gear 13 drives the gear rod 18 meshing therewith and is limited in the vertical direction by the fixed block 2 17, so that the gear rod 18 moves vertically downward, and the bottom of the gear rod 18 drives the rotating column 19 to move synchronously, so that the rotating column 19 pushes the swivel 20 to rotate counterclockwise about the connection between the fixed block 2 17 and the swivel 20 as the axis, so that the lower half of the swivel 20 with its center of circle as a reference object swings toward the direction close to the medical oxygen vehicle 1, so that the swivel 20 pushes and slides on the rotating column 21, and at this time, the rotating column 21 rotates on the sliding rod 23, and pushes the sliding rod 23 in the horizontal direction to slide on the limit block 22 in the direction close to the medical oxygen vehicle 1, and the protrusion 24 continuously slides inside the rotating column 19 at both ends of the swivel 20, which prevents the swivel 20 from falling off the rotating column 19.

[0059] The working steps of the brake component are as follows:

[0060] As mentioned above, at this time, the sliding rod 23 pushes the sliding plate 27 to slide on the bottom of the medical oxygen cart 1 and approach the wheel 25, and the sliding plate 27 drives the block 28 to move in the direction close to the wheel 25. At this time, the block 28 hits the gap between the multiple inclined blocks 26. Even if the gap between two adjacent inclined blocks 26 cannot be completely aligned with the block 28, the staff can hold the handle 2 and push the cart slightly back and forth to ensure that the gap between the two inclined blocks 26 is engaged with the block 28, and then the two groups of blocks 28 engage and clamp the two inclined blocks 26, so as to carry out the above. When replacing or installing the oxygen cylinder, the wheel 25 will be stopped by the clamping, thereby increasing the stability when installing or replacing the oxygen cylinder.

[0061] The connection assembly and the brake assembly cooperate with each other to achieve the effect of engaging and braking the wheel 25, thereby preventing the movement of the medical oxygen cart 1, thereby increasing the stability when replacing or installing the oxygen cylinder, and avoiding the medical oxygen cart 1 from moving and falling when installing or replacing the oxygen cylinder.

[0062] When the oxygen cylinder is installed or replaced, the staff connects the airway to the oxygen outlet of the oxygen cylinder and adjusts the oxygen cylinder to an oxygen concentration suitable for the biological reagent bottles in the biological reagent box 4, so that the biological reagent bottles are sent to the biomedical center for medical research. The mutual adaptation of the medical oxygen cart 1, the handle 2 and the wheel 25 can facilitate the transportation of biological reagent bottles. At the same time, it can ensure that the biological reagent bottles are at a suitable oxygen concentration. At the same time, the person and the medical oxygen cart 1 move in a parallel state, so that the staff can more easily transport the biological reagent bottles to the biomedical center.

[0063] The above components are linked to each other to solve the problem of transporting oxygen bottles while transporting biological reagent bottles, so that when oxygen supply is needed for transporting biological reagent bottles, oxygen can be directly supplied to them through oxygen.
