DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, the present invention provides an intelligent medical nursing frame, including a placement frame 1, the bottom end of the placement frame 1 is rotatably connected with a roller 2 and a rotating shaft 3, a transmission wheel 4 is fixedly installed in the middle of the roller 2 and the rotating shaft 3, and a transmission belt 5 is connected to the surface of the transmission wheel 4 for transmission, and a long gear 6 is fixedly installed at both the front and rear ends of the rotating shaft 3, and a short gear 7 is meshed above the long gear 6. The rotating shaft 3 is located above the roller 2. Since the roller 2 is in contact with the ground, the movement of the device will drive the roller 2 to rotate, and then drive the rotating shaft 3 to rotate, and finally realize the driving of the long gear 6 and the short gear 7 to rotate, as shown in FIG. Figure 1 As shown, with the left side as the forward direction, when the device moves forward, the roller 2 rotates counterclockwise, the long gear 6 rotates counterclockwise, and the short gear 7 rotates clockwise;

[0032] The bottom end of the placing frame 1 is rotatably connected to a driven roller 8, the middle and right ends of the placing frame 1 are rotatably connected to guide rollers 9, and the right side of the bottom end of the placing frame 1 is provided with a main roller 10 and a waste roller 11. The plastic film on the main roller 10 is as shown in FIG. Figure 8 As shown, it contacts the driven roller 8 and the guide roller 9 in sequence, and is finally fixed on the waste roller 11;

[0033] A limit frame 39 is fixedly installed on the top surface of the placement rack 1, and a connecting frame 12 is movably connected to the middle of the limit frame 39. A cutting knife 13 is fixedly installed on the bottom surface of the connecting frame 12. The limit frame 39 is set to limit the upward movement of the connecting frame 12 to prevent the connecting frame 12 and the cutting knife 13 from moving too long. The cutting knife 13 is responsible for cutting the plastic film;

[0034] A support block 17 is fixedly installed at the right end of the top surface of the placement rack 1, and a movable handrail 18 is movably connected to the top of the support block 17. An oil pipe 19 is fixedly installed at the bottom end of the support block 17, and a positioning sleeve 20 is movably connected to the middle part of the oil pipe 19. A damper is provided at the sliding part between the positioning sleeve 20 and the placement rack 1 to ensure that the positioning sleeve 20 will move only after the oil pressure in the oil pipe 19 increases. The bottom end of the positioning sleeve 20 is sleeved on the short gear 7. The movement of the movable handrail 18 in the support block 17 is responsible for driving the hydraulic oil to flow in the oil pipe 19, thereby controlling the lifting and lowering of the plug 32 and controlling the forward and backward movement of the positioning sleeve 20;

[0035] Both the front and rear ends of the driven roller 8 are provided with connecting grooves 22. The end of the short gear 7 close to the driven roller 8 is fixedly installed with a connecting shaft 21. When the driven roller 8 rotates, it drives the plastic film to be transported, so that after the packaged medical waste is taken away, the uncut plastic film is provided to the bottom of the cutting knife 13. The rotation of the driven roller 8 is driven by the connecting shaft 21 inserted into the connecting groove 22. When the connecting shaft 21 and the connecting groove 22 are separated, the driven roller 8 will not rotate.

[0036] The rolled plastic film is guided by the driven roller 8 and the two guide rollers 9 so that the plastic film passes under the cutting knife 13. When the device moves, the rotation of the long gear 6 driven by the roller 2 can drive the cutting knife 13 to lift up. The movement of the movable armrest 18 controls the rotation of the driven roller 8 to drive the plastic film to move. When the device is no longer moving, the movable armrest 18 is pulled out of the support block 17. The cutting knife 13 moves downward under the action of gravity to cut the plastic film so that the plastic film is spread on the placement rack 1, thereby providing a packing tape for medical waste. After the medical waste used by the nursing staff is directly placed on the plastic film, the cut plastic film can be directly taken out to collect and pack the medical waste. During the whole process, there is no direct contact between the device and the medical waste, and no cleaning and disinfection is required. The operation is simple and convenient.

[0037] The connecting frame 12 is a hollow rectangle, the width of the connecting frame 12 is smaller than the length of the main roller 10, and the waste roller 11 is located above the connecting frame 12;

[0038] It is ensured that the cutting knife 13 can smoothly cut off the plastic film during the downward movement, and the plastic film will not be cut off as a whole.

[0039] The bottom surface of the placement rack 1 is fixedly mounted with a mounting rack 14, the right side of the mounting rack 14 is provided with a placement slot 15, the inner cavity of the placement slot 15 is movably connected with a locking pin 16, and the waste roller 11 and the main roller 10 are both rotatably connected in the mounting rack 14;

[0040] A locking pin 16 that can move up and down can be provided to fix and unlock the main roller 10 and the waste roller 11, so as to facilitate replacement of the new main roller 10. After the main roller 10 is used up, it can be directly used as the waste roller 11, thus saving the use cost.

[0041] The axes of the short gear 7 and the long gear 6 are on the same straight line, the short gear 7 is wrapped by the bottom end of the positioning sleeve 20, and the top end of the positioning sleeve 20 is movably connected to the placement frame 1;

[0042] The movement of the positioning sleeve 20 can drive the short gear 7 to move forward and backward. During the movement of the short gear 7 forward and backward, the short gear 7 always keeps in meshing with the long gear 6.

[0043] The support block 17 is connected to the oil pipe 19, a fixed pipe 31 is fixedly installed at the left end of the oil pipe 19, a plug 32 is movably connected to the bottom end of the fixed pipe 31, and the oil pipe 19, the support block 17 and the fixed pipe 31 are filled with hydraulic oil;

[0044] Slide the movable armrest 18 in the support block 17 so that the first scale on the movable armrest 18 is retracted into the support block 17. At this time, the hydraulic oil in the support block 17 pushes the plug 32 downward through the oil pipe 19 and the fixed pipe 31, so that the plug 32 blocks the exhaust hole 33, thereby closing the air box 25, ensuring that the air box 25 can be closed after air intake, and ensuring that the connecting rod 27 can move smoothly.

[0045] Among them, a gas tank 23 is fixedly installed at the bottom end of the placement rack 1, a one-way air inlet valve and a one-way air outlet pipe are fixedly installed at the left end of the gas tank 23, the gas box 25 is connected to the one-way air outlet pipe, the inner cavity of the gas tank 23 is movably connected to the piston head 24, the right side of the piston head 24 is fixedly installed with a connecting frame 38, the inner cavity of the connecting frame 38 is movably connected to a rotating rod 37, and the rotating rod 37 is fixed on the short gear 7;

[0046] The rotation of the long gear 6 drives the short gear 7 to rotate, and then drives the rotating rod 37 to rotate around the axis of the short gear 7. Through the movable connection between the rotating rod 37 and the connecting frame 38, the piston head 24 can be driven to continuously move left and right to continuously draw external air into the air box 25.

[0047] Among them, an air box 25 is fixedly installed at the bottom end of the placement rack 1, a placement box 30 is fixedly installed on the left side of the placement rack 1, an air pipe 26 is fixedly installed on the left side of the air box 25, and the inner cavity of the air pipe 26 is fixedly and movably connected with a connecting rod 27, a spring 28 is fixedly installed between the inner cavity of the air pipe 26 and the right end of the connecting rod 27, and a clamping plate 29 is fixedly installed on the left end of the connecting rod 27, and the clamping plate 29 is movably connected in the placement box 30;

[0048] When the gas in the gas box 25 increases, the connecting rod 27 is pushed to move left, so that as long as the device moves, the clamp 29 can automatically move left to clamp the medicine to prevent the medicine from falling down. After the device reaches the patient, with the reset of the movable armrest 18, the exhaust hole 33 opens, and the spring 28 drives the clamp 29 to reset and automatically release the medicine for easy taking.

[0049] The top of the air box 25 is provided with an exhaust hole 33, the plug 32 is located directly above the exhaust hole 33, the diameter of the bottom of the plug 32 is equal to the diameter of the exhaust hole 33, the bottom of the front and rear sides of the air box 25 are fixedly installed with connecting pipes 34, the top of the connecting pipe 34 is fixedly installed with a pressure relief pipe 35, the inner cavity of the pressure relief pipe 35 is movably connected with a connecting block 36, and the connecting block 36 is fixedly connected to the connecting frame 12;

[0050] The provision of the exhaust hole 33 ensures that, when the device is not moving, the air in the air box 25 can be smoothly exhausted, thereby achieving the cutting of the plastic film and unlocking the medicine.

[0051] Among them, the movable armrest 18 can be retracted into the support block 17 and has two scale lines;

[0052] Two scale lines are set, wherein the first scale line represents that the exhaust hole 33 is blocked by the plug 32 and the driven roller 8 does not rotate, and the second scale line represents that the exhaust hole 33 is blocked and the driven roller 8 also rotates.

[0053] The working principle and use process of the present invention:

[0054] When in use, pull up the locking pin 16 to open the mounting frame 14, then put the main roller 10 and the waste roller 11 into the mounting frame 14, release the locking pin 16, slide the locking pin 16 downward to fix the main roller 10 and the waste roller 11 in the mounting frame 14, then pull the plastic film on the main roller 10 to the left, pass under the driven roller 8, pass the guide roller 9 on the left, pull it to the right, pass under the cutting knife 13, pass the guide roller 9 on the right, and then wrap around the waste roller 11;

[0055] The nursing staff can place the medicines to be used in the placement box 30, and can place them on the left and right sides of the three clamps 29 according to the size of the medicines, and then push the device to the left by holding the movable armrest 18, and then move it to the patient;

[0056] When moving, slide the moving handrail 18 in the support block 17 so that the first scale on the moving handrail 18 is received in the support block 17. At this time, the hydraulic oil in the support block 17 pushes the plug 32 downward through the oil pipe 19 and the fixed pipe 31, so that the plug 32 blocks the exhaust hole 33. The contact between the roller 2 and the ground drives the rotating shaft 3 to rotate through the transmission wheel 4 and the transmission belt 5, and then drives the long gear 6 to rotate. The engagement of the long gear 6 and the short gear 7 can drive the short gear 7 and the rotating rod 37 to rotate. At this time, the connecting groove 22 and the connecting shaft 21 are in a separated state, the driven roller 8 will not rotate, and the rotation of the rotating rod 37 can drive the connecting groove 22 and the connecting shaft 21 to rotate. The connecting frame 38 continuously slides left and right, so that the piston head 24 continuously slides left and right in the gas tank 23, thereby sucking the outside air into the gas tank 23, and then transporting it to the gas box 25 through the gas tank 23, so that the air pressure in the gas box 25 increases, thereby pushing the connecting rod 27 to move left, driving the clamping plate 29 to move left in the placement box 30 to clamp the medicine, and at the same time, the gas will also enter the pressure relief pipe 35 through the connecting pipe 34, pushing up the connecting block 36, thereby driving the connecting frame 12 to move up, so that the cutting knife 13 moves up, and when the clamping plate 29 and the connecting block 36 cannot move, the pressure is relieved through the pressure relief valve set at the top of the pressure relief pipe 35;

[0057] Then continue to move the movable handrail 18 so that the second scale line is received in the support block 17. At this time, the pressure in the oil pipe 19 reaches a pressure sufficient to push the positioning sleeve 20 to move, and then push the positioning sleeve 20 toward the center of the placement rack 1, so that the positioning sleeve 20 drives the short gear 7 to move, and the connecting shaft 21 is inserted into the connecting groove 22. At this time, the rotating short gear 7 can drive the driven roller 8 to rotate, and then drive the plastic film to be rolled up on the waste roller 11. When the intact part of the plastic film is all located below the cutting knife 13, the movable handrail 18 is pulled out until the second scale line leaks out. At this time, the connecting shaft 21 is pulled back, and the driven roller 8 no longer rotates;

[0058] When the patient's position is reached, the device no longer moves, the long gear 6 no longer rotates, the gas tank 23 stops supplying air to the gas box 25, and after the movable armrest 18 is completely pulled out, the plug 32 is separated from the exhaust hole 33. At this time, the air in the gas box 25 and the connecting pipe 34 is discharged through the exhaust hole 33. Under the action of the gravity of the connecting frame 12 and the cutting knife 13, the cutting knife 13 moves down and resets quickly to press on the plastic film to cut off the plastic film. The spring 28 in the compressed state pushes the connecting rod 27 and the clamp 29 back to reset under the action of the elastic force, and no longer clamps the medicine.
