Description

Technical Field

[0001] This invention relates to the field of medical device manufacturing technology, and more specifically, to a endotracheal tube manufacturing and cutting device. Background Technology

[0002] Endotracheal intubation is a commonly used medical technique in emergency care and clinical practice. Endotracheal intubation is a surgical procedure in which a special tube is inserted into the trachea through the cavity or nasal cavity. It is mainly used to maintain airway patency, assist breathing, and clear secretions. It is a key measure for rescuing patients with respiratory dysfunction.

[0003] However, the existing endotracheal tube production process still has shortcomings in the production equipment. Most existing production equipment cuts the tubes into flat ends during the cutting process, but the finished endotracheal tubes need to be cut into bevels. Therefore, a bevel cutting process is required, which is not conducive to efficient production and increases the workload of workers. At the same time, burrs are easily generated at the cut ends. If the burrs are not removed, they may cause the patient's trachea to be cut during use, which may affect the patient's life safety. Finally, during the cooling of the tubes, the tubes are easily bent and deformed due to their own weight and the impact of water flow. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides a endotracheal tube production and cutting device to solve the technical problems mentioned in the background art. Technical solution

[0005] To achieve the above objectives, the present invention provides the following technical solution: a endotracheal tube production and cutting device, comprising a worktable, a cutting mechanism and a grinding mechanism on the worktable, the cutting mechanism comprising a support frame, a hydraulic cylinder, a hydraulic push rod, a cutting blade and a bidirectional lead screw, the support frame being installed on one side of the worktable, the hydraulic cylinder being installed on the upper surface of the support frame, the output end of the hydraulic cylinder passing through the support frame and connecting to the hydraulic push rod, the lower end of the hydraulic push rod being connected to the cutting blade, an installation groove being formed on the surface of the worktable, the bidirectional lead screw being placed in the installation groove, the grinding mechanism comprising a slide rail, a slide seat, a connecting seat, a limiting sleeve, a universal ball and a grinding head, two slide rails being provided, respectively installed on both sides of the middle of the worktable, the slide seat being slidably connected to the slide rail, the connecting seat being fixedly connected to the slide seat, the top of the connecting seat being connected to the bottom of the limiting sleeve, the universal ball being embedded in the limiting sleeve, one end of the universal ball being connected to the grinding head, and an anti-corrosion layer being provided on the surface of the worktable.

[0006] The invention is further configured such that the surface of the workbench is provided with a cutting groove that cooperates with the cutting blade, and the workbench is provided with a control unit, a drive module and a data storage module. The drive module and the data storage module are respectively connected to the control unit, and the hydraulic cylinder and the hydraulic push rod are respectively connected to the drive module, so as to ensure that the pipe can be completely cut off and avoid the phenomenon of incomplete cutting.

[0007] The invention is further configured such that two moving blocks are threadedly connected to the outer surface of the bidirectional lead screw, and connecting rods are connected to the upper surfaces of the two moving blocks. Clamping plates are fixedly connected to the opposite surfaces of the two connecting rods, so as to clamp pipes of different diameters and prevent displacement during the cutting process.

[0008] The invention is further configured such that a drive motor is installed on one side of the workbench, and the output end of the drive motor passes through the mounting groove and is connected to one end of a bidirectional lead screw, thereby improving the ease of use of the equipment.

[0009] The invention is further configured such that one end of the universal ball is connected to a drive host, and the drive host is covered with a host handle for easy gripping by the operator, allowing control of the direction and force of the grinding head during grinding, thus improving controllability.

[0010] The invention is further configured such that a clamping sleeve is provided between the two slide rails, and a screw is connected to the top of the clamping sleeve. One end of the screw extends into the clamping sleeve and is connected to an arc-shaped clamping block to prevent the pipe from shaking during the grinding process, which would result in uneven grinding.

[0011] The invention is further configured such that a cooling mechanism is provided on the workbench, the cooling mechanism including a cooling box, a spray frame, a nozzle, a water pump, a delivery pipe, and a pumping pipe. The cooling box is installed on the surface of the workbench, the spray frame is installed inside the cooling box and its two ends are connected to the two sides of the cooling box, the nozzle is installed on the lower surface of the spray frame, and a water pump is installed on the top of the cooling box. One end of the water pump is connected to the delivery pipe, and the other end is connected to the pumping pipe. One end of the delivery pipe extends into the interior of the cooling box and is connected to the spray frame, which can effectively reduce the temperature of the pipe, prevent the pipe from undergoing thermal deformation, and wash away some debris.

[0012] The invention is further configured such that through holes are provided at both ends of the cooling box, and a drain pipe is provided at the lower end of the cooling box, with one end of the drain pipe extending into the workbench, so that the water used for cooling can be discharged from the drain pipe, ensuring that the inside of the cooling box is clean.

[0013] The invention is further configured such that a rotating shaft is installed inside the cooling box, with both ends of the rotating shaft connected to the two inner ends of the cooling box respectively, and one side of the rotating shaft extending out of the cooling box and connected to a rotary motor. Several rollers are installed at equal intervals on the rotating shaft, and brushes are installed between the rollers. The rollers provide rolling support for the pipe and prevent bending due to gravity. The brushes can clean debris from the surface of the pipe.

[0014] The present invention is further configured such that four support legs are fixedly installed on the lower surface of the worktable to maintain the stability of the worktable.

[0015] The present invention is further configured such that the anti-corrosion coating comprises the following components: 54.5-68.1% resin, 9.5-14.8% curing agent, 10-15% self-made titanium-molybdenum alloy nanopowder, 10-15% self-made modified wear-resistant and anti-friction filler, and 0.5-0.8% additives; the percentages are by mass, which further improves the service life of the workbench. Beneficial effects

[0016] Compared with the prior art, the present invention provides a endotracheal tube production and cutting device, which has the following beneficial effects: The cutting mechanism uses a hydraulic cylinder to drive a hydraulic push rod, which in turn drives the cutting blade to cut the pipe. Compared with traditional cutting methods, the cutting force is greater, ensuring that the cut is completed in one go without any uncut sections, thus improving efficiency. Through the combination of a two-way lead screw, a moving block, and a clamping plate, synchronous clamping can be achieved, ensuring that pipes of different diameters are clamped and ensuring the stability of the pipe during the cutting process, avoiding shaking that could lead to cutting failure.

[0017] The grinding mechanism, through the cooperation of the slide rail and slide base, allows the grinding head to move along the slide rail via the connecting seat. The universal ball and main unit handle allow the operator to freely rotate the angle of the grinding head and better control the force, making the operation more flexible and convenient. The clamping sleeve, together with the arc-shaped clamping block and screw, can better fix the pipe during the grinding process, effectively preventing the pipe from shaking during grinding, which could lead to uneven grinding or even damage to the pipe.

[0018] The cooling mechanism, through the setup of a cooling box, spray rack, and nozzles, can cool the pipes after cutting or grinding, effectively reducing the temperature generated during pipe processing and preventing thermal deformation due to high temperatures. At the same time, rollers and brushes can sweep away debris from the pipe surface and provide rolling support for the pipes, preventing bending due to gravity, ensuring the surface cleanliness of the pipes, and improving the product's appearance quality.

The output end of the hydraulic cylinder 3 passes through the support frame 2 and connects to the hydraulic push rod 4. The lower end of the hydraulic push rod 4 is connected to the cutting blade 5. An installation groove 7 is opened on the surface of the worktable 1, and the double-acting lead screw 6 is placed in the installation groove 7. The grinding mechanism includes a slide rail 8, a slide seat 9, a connecting seat 10, a limiting sleeve 11, a universal ball 12, and a grinding head 13. Two slide rails 8 are provided. The slide 9 and slide rail 8 are slidably connected, and the connecting seat 10 is fixedly connected to the slide 9. The top of the connecting seat 10 is connected to the bottom of the limiting sleeve 11. The universal ball 12 is embedded in the limiting sleeve 11. One end of the universal ball 12 is connected to the grinding head 13. The surface of the worktable 1 has a cutting groove 14 that cooperates with the cutting blade 5. The worktable is equipped with a control unit, a drive module and a data storage module. The drive module and the data storage module are respectively connected to the control unit. The hydraulic cylinder and the hydraulic push rod are respectively connected to the drive module to ensure that the pipe can be completely cut and avoid the phenomenon of incomplete cutting.

[0026] The workbench 1 is equipped with a control unit, a drive module, and a data storage module. The drive module and the data storage module are connected to the control unit, which is preferably a PLC programmable controller. The PLC programmable controller controls the drive module, and the data storage module stores the relevant data generated during the operation of the equipment.

[0027] The outer surface of the bidirectional lead screw 6 is threaded with two moving blocks 15. The upper surfaces of the two moving blocks 15 are connected with connecting rods 16. The two connecting rods 16 are fixedly connected with clamping plates 17 on opposite sides, so as to clamp pipes of different diameters and prevent them from shifting during the cutting process.

[0028] A drive motor 18 is installed on one side of the workbench 1. The output end of the drive motor 18 passes through the mounting slot 7 and is connected to one end of the bidirectional lead screw 6, which improves the ease of use of the equipment.

[0029] One end of the omnidirectional ball 12 is connected to the drive host 19. The drive host 19 is covered with a host handle 20, which is convenient for the staff to hold. During grinding, the direction and force of the grinding head 13 can be controlled, improving controllability.

One end of the screw 22 extends into the clamping sleeve 21 and is connected to an arc-shaped clamping block 23 to prevent the pipe from shaking during the grinding process, which would result in uneven grinding.

[0031] In this embodiment, when the device is needed, the insertion tube is first placed between the clamping plates 17, and the position where the insertion tube needs to be cut is placed on the cutting groove 14. Then, the drive motor 18 is started, causing the drive motor 18 to drive the bidirectional lead screw 6 to rotate, thereby driving the moving block 15 to move in opposite directions. Then, the clamping plates 17 are driven by the connecting rod 16 to clamp and fix the insertion tube. Then, the hydraulic cylinder 3 is started to push the hydraulic push rod 4 to drive the cutting blade 5 to descend, and the insertion tube is cut at an angle. After the cutting is completed, the cut end is fixed by the clamping sleeve 21. The clamping sleeve 21 consists of two semi-circular rings. One end of the two semi-circular rings is rotatably connected, and the other end is snapped together. When fixing, first open the clamping sleeve 21, place one end of the cut insertion tube into the clamping sleeve 21, and then rotate the screw 22 to drive the arc-shaped clamping block 23 to fix the insertion tube. Then, push the slide block 9 to move towards the insertion tube through the slide rail 8. After moving to the appropriate position, turn on the drive host 19 to drive the grinding head 13 to rotate at high speed. Hold the host handle 20 and use the universal ball 12 to drive the grinding head 13 to adjust the angle to grind the end of the insertion tube and remove the burrs generated after cutting.

[0032] Please see Figure 1 and Figure 5 As a further embodiment of the equipment: a cooling mechanism is provided on the workbench 1, which includes a cooling box 24, a spray frame 25, a nozzle 26, a water pump 27, a delivery pipe 28, and a water suction pipe 29. The cooling box 24 is installed on the surface of the workbench 1, the spray frame 25 is installed inside the cooling box 24 and its two ends are connected to the two sides of the cooling box 24, the nozzle 26 is installed on the lower surface of the spray frame 25, and a water pump 27 is installed on the top of the cooling box 24. One end of the water pump 27 is connected to the delivery pipe 28, and the other end is connected to the water suction pipe 29. One end of the delivery pipe 28 extends into the interior of the cooling box 24 and is connected to the spray frame 25, which can effectively reduce the temperature of the pipe, prevent the pipe from thermally deforming, and wash away some debris.

[0033] The cooling box 24 has through holes 30 at both ends and a drain pipe 31 at the bottom. One end of the drain pipe 31 extends out of the workbench 1, allowing the used water to be discharged from the drain pipe 31, ensuring that the inside of the cooling box 24 is clean.

[0034] A rotating shaft 32 is installed inside the cooling box 24. The two ends of the rotating shaft 32 are connected to the two ends of the inner side of the cooling box 24 respectively. One side of the rotating shaft 32 extends out of the cooling box 24 and is connected to a rotary motor 33. Several rollers 34 are installed at equal intervals on the rotating shaft 32. Brushes 35 are installed between the rollers 34. The rollers 34 provide rolling support for the pipe and prevent bending due to gravity. The brushes 35 can clean debris from the surface of the pipe.

[0035] Four support legs 36 are fixedly installed on the lower surface of the worktable 1 to maintain the stability of the worktable 1.

[0036] More specifically, when it is necessary to cool down the polished tube, first insert the tube through the through hole 30 on the side near the polishing mechanism and out through the through hole 30 on the other side. Then turn on the water pump 27 and the rotary motor 33. The water pump 27 draws water up through the water pipe 29 and then delivers the water to the spray frame 25 through the delivery pipe 28. The water is then sprayed onto the tube through the nozzle 26. The rotary motor 33 drives the rotating shaft 32 to rotate, thereby driving the roller 34 and the brush 35 to rotate. The roller 34 can prevent the tube from deforming due to the water flow and its own weight. The brush 35 can sweep away the debris remaining on the surface of the tube after polishing. Wastewater generated during the operation will be discharged through the drain pipe 31 at the bottom of the cooling box 24.

[0037] In summary, when using or operating the entire equipment: First, place the insertion tube between the clamping plates 17, place the part of the insertion tube to be cut on the cutting groove 14, then start the drive motor 18 to drive the bidirectional lead screw 6 to rotate, thereby driving the moving block 15 to move in the opposite direction. Then, the connecting rod 16 drives the clamping plates 17 to clamp and fix the insertion tube. Then, start the hydraulic cylinder 3 to push the hydraulic push rod 4 to drive the cutting blade 5 to descend and cut the insertion tube at an angle. After the cutting is completed, the cut end is clamped by the clamping sleeve 21. For fixing, the clamping sleeve 21 consists of two semi-circular rings. One end of the two semi-circular rings is rotatably connected, and the other end is snapped together. When fixing, first open the clamping sleeve 21, place one end of the cut insertion tube into the clamping sleeve 21, and then rotate the screw 22 to drive the arc-shaped clamping block 23 to fix the insertion tube. Then, push the slide block 9 towards the insertion tube through the slide rail 8. After moving to the appropriate position, turn on the drive host 19 to drive the grinding head 13 to rotate at high speed. Hold the host handle 20 and use the universal ball 12 to drive the grinding head 13 to adjust the angle to grind the end of the insertion tube and remove the burrs generated after cutting.

[0038] When it is necessary to cool down the polished tube, first insert the tube through the through hole 30 on the side near the polishing mechanism and out through the through hole 30 on the other side. Then turn on the water pump 27 and the rotary motor 33. The water pump 27 draws water up through the water pipe 29 and then delivers the water to the spray frame 25 through the delivery pipe 28. Then spray the water onto the tube through the nozzle 26. The rotary motor 33 drives the rotating shaft 32 to rotate, thereby driving the roller 34 and the brush 35 to rotate. The roller 34 can prevent the tube from deforming due to the water flow and its own weight. The brush 35 can sweep away the debris left on the surface of the tube after polishing. Wastewater generated during the operation will be discharged through the drain pipe 31 at the bottom of the cooling box 24.

[0039] The anti-corrosion coating comprises the following components: 54.5-68.1% resin, 9.5-14.8% curing agent, 10-15% self-made titanium-molybdenum alloy nanopowder, 10-15% self-made modified wear-resistant and anti-friction filler, and 0.5-0.8% additives; the percentages are by mass. In its preparation, the preferred mass percentages are: 50-55% titanium coarse powder, 37-42% molybdenum coarse powder, 3% dispersant, 5% bonding agent, and 0.5% additives. It is then fed into external production equipment, and after obtaining the finished product, it is applied to the surface of the workbench 1 using a spraying tool or a coating brush.

[0040] In all the solutions mentioned above, for connections between two components, welding, bolt and nut connection, bolt or screw connection, or other known connection methods can be selected according to the actual situation. These will not be elaborated here. For all fixed connections mentioned above, welding is preferred. The above are merely preferred embodiments of this application and are not intended to limit the invention. Although this application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features.
