Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a endotracheal tube anti-dislodgement protection mechanism. Background Technology

[0002] When hospital patients experience airway obstruction or even difficulty breathing, medical staff typically use intubation to assist respiration. This involves inserting a tube into the patient's body and connecting it to the ventilator tubing. Before intubation, the patient is given anesthesia, and then the throat is opened. The tube is then manually inserted into the trachea. After the tube is properly inserted, it is usually secured in place with adhesive tape to prevent accidental pulling and subsequent breathing difficulties. Currently, the tape is applied around the patient's mouth to hold the tube in place. However, each time the tube is removed, the tape must be removed piece by piece, which can easily injure the patient's skin. Furthermore, securing and removing the tube is extremely inconvenient. Therefore, a tracheal intubation anti-dislodgement protection mechanism is being developed to overcome these shortcomings. Summary of the Invention

[0003] An anti-dislodgement protection mechanism for endotracheal tubes includes a mounting plate, a strap, a hollow tube, clamping blocks, a compression tube, a first wedge block, a first spring, and threaded rods. The hollow tube is fixed on the mounting plate, and a strap is provided on the side of the mounting plate. The clamping blocks are symmetrically arranged and slidably connected inside the hollow tube. A connector is provided at the end of the tube and is connected to the tubing of a ventilator. The compression tube is slidably connected to the outside of the hollow tube. The first wedge block is fixedly connected to the outer wall of each clamping block and is in a compression fit with the compression tube. A first spring is connected between each clamping block and the hollow tube. The mounting plate is rotatably connected to symmetrically arranged threaded rods, and the threaded rods are threadedly connected to the compression tubes.

[0004] Further explanation: It also includes a winding rod, a first torsion spring, a first bevel gear, a second bevel gear, a magnet block, and an electromagnet. The winding rod is rotatably connected inside the mounting plate. The winding rod is fixedly connected to the strap. The first torsion spring is connected between the bottom of the winding rod and the bottom of the mounting plate. The first bevel gear is slidably connected to the winding rod. The first bevel gear meshes with the second bevel gear. The second bevel gear is fixedly connected to a threaded rod near the winding rod. An electromagnet is fixedly connected to the winding rod. A magnet block is connected to the side of the first bevel gear near the electromagnet. The magnet block and the electromagnet are magnetically attracted to each other.

[0005] To further explain, it also includes a rotating handle, which is fixedly connected to the top of the winding rod.

[0006] To further explain, it also includes a pressure sensor. The clamping blocks are equipped with a pressure sensor on one side close to each other. The pressure sensor and the electromagnet are electrically connected through the control module.

[0007] Further explanation: It also includes a locking mechanism for locking the take-up bar. The locking mechanism includes a ratchet, ratchet teeth, a stop block, a second torsion spring, and a pressure frame. A ratchet is fixedly connected to the take-up bar, and the ratchet teeth are engaged with the ratchet teeth. The ratchet teeth are rotatably connected to the mounting plate. A stop block is fixedly connected to the side of the mounting plate near the ratchet teeth. The stop block and the ratchet teeth are in a pressing fit. A second torsion spring is connected between the bottom of the ratchet teeth and the mounting plate. A pressure frame is rotatably connected to the side of the ratchet teeth away from the second torsion spring. The pressure frame is slidably connected to the mounting plate.

[0008] To further explain, it also includes a bevel gear set, a twisted shaft, and a bite plate. The twisted shaft is rotatably connected to the side of the mounting plate away from the winding rod, and the bite plates are symmetrically arranged and slidably connected to the side of the mounting plate away from the extrusion tube. The bite plates and the twisted shaft are threadedly connected, and the bevel gear set is connected between the rear part of the nearby threaded rod and the twisted shaft.

[0009] To further explain, the bevel gear set consists of two bevel gears, one of which is connected to the end of a nearby threaded rod, while the other bevel gear is fixedly connected to a twisted shaft.

[0010] Further explanation: It also includes a support plate, a mounting base, a second wedge block, a second spring, and a telescopic rod. The support plate is fixedly connected to the bottom of the mounting plate. The support plate is connected to symmetrically arranged mounting bases. The mounting bases are used to hold the connector head. The mounting bases are slidably connected to symmetrically arranged second wedge blocks. A second spring is connected between the second wedge block and the mounting base. The mounting bases are connected to symmetrically arranged telescopic rods. The second springs are sleeved on the outside of the telescopic rods. The ends of the telescopic rods are fixedly connected to the second wedge blocks.

[0011] To further explain, it also includes an inclined frame, a column, a lower pressure frame, and a third spring. The inclined frame is fixedly connected to the second wedge block, and the lower pressure frame is slidably connected inside the mounting plate. The lower pressure frame and the pressing frame are fixedly connected. A third spring is connected between the lower pressure frame and the top of the mounting plate. The column is connected to the side of the lower pressure frame near the inclined frame, and the column and the inclined frame are in a pressing fit.

[0012] To further explain, it also includes an ejector and a fourth spring. The ejector is slidably connected inside the card holder, and the bottom of the ejector and the card holder are connected to the fourth spring.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention rotates the rotating handle to rotate the winding rod to wind up the strap, so that the strap is fastened to the patient's head. At the same time, through the second bevel gear and the first bevel gear, the squeezing tube moves backward to squeeze the first wedge block, so that the clamping block automatically clamps the catheter, making it convenient to install and remove the catheter.

[0014] 2. When the extrusion tube moves forward, the threaded rod on the left side will rotate. The rotation of the bevel gear set will cause the twisted shaft to rotate, thereby driving the occlusal plates to move closer to each other to adjust the gap, so as to adjust the position of the occlusal plates. The occlusal plates can prevent the patient from biting the catheter by pressing against the patient's teeth.

[0015] 3. The present invention can restrict the connector by using the second wedge block, thereby improving the connection between the connector and the ventilator tube. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0023] Example 1 A endotracheal tube anti-dislodgement protection mechanism, such as Figures 1-2As shown, the device includes a mounting plate 2, a strap 201, a hollow tube 3, a clamping block 4, a compression tube 5, a first wedge block 6, a first spring 7, and a threaded rod 8. The hollow tube 3 is fixedly connected to the middle of the mounting plate 2. The strap 201 is provided on the side of the mounting plate 2. The clamping blocks 4 are slidably connected to both the upper and lower sides of the hollow tube 3. The clamping blocks 4 are used to clamp the tubing 1. The end of the tubing 1 is provided with a connector 101, which is connected to the tubing of the ventilator. The compression tube 5 is slidably connected to the outside of the hollow tube 3. The first wedge block 6 is fixedly connected to the side of the clamping blocks 4 that is far apart from each other. The first wedge block 6 and the compression tube 5 are squeezed together. The first spring 7 is connected between the clamping blocks 4 and the hollow tube 3. The threaded rod 8 is rotatably connected to the left and right sides of the front of the mounting plate 2. The threaded rod 8 is threadedly connected to the compression tube 5.

[0024] like Figures 2-3 As shown, it also includes a winding rod 9, a rotating handle 10, a first torsion spring 11, a first bevel gear 12, a second bevel gear 13, a magnet block 14, an electromagnet 15, and a pressure sensor 151. The winding rod 9 is rotatably connected to the right side of the mounting plate 2. The winding rod 9 is fixedly connected to the right end of the strap 201. The winding rod 9 is used to wind up the strap 201. The rotating handle 10 is fixedly connected to the top of the winding rod 9. The first torsion spring 11 is connected between the bottom of the winding rod 9 and the bottom of the mounting plate 2. The first bevel gear 12 is slidably connected to the middle of the winding rod 9. The first bevel gear 12 meshes with the second bevel gear 13. The second bevel gear 13 is fixedly connected to the rear end of the threaded rod 8 on the right. The electromagnet 15 is fixedly connected to the winding rod 9. The magnet block 14 is fixedly connected to the top of the first bevel gear 12. The magnet block 14 and the electromagnet 15 are magnetically attracted to each other. The clamping blocks 4 are provided with a pressure sensor 151 on one side close to each other. The pressure sensor 151 and the electromagnet 15 are electrically connected through the control module.

[0025] It also includes a locking mechanism for locking the take-up bar 9. The locking mechanism includes a ratchet 16, a ratchet 17, a stop block 18, a second torsion spring 19, and a pressure frame 20. The upper end of the take-up bar 9 is fixedly connected to the ratchet 16, which engages with the ratchet 17. The ratchet 17 is rotatably connected to the mounting plate 2. The stop block 18 is fixedly connected to the side of the mounting plate 2 near the ratchet 17. The stop block 18 and the ratchet 17 are pressed together. The bottom of the ratchet 17 is connected to the mounting plate 2, and the top of the ratchet 17 is rotatably connected to the pressure frame 20. The pressure frame 20 is slidably connected to the upper part of the mounting plate 2.

[0026] When medical staff need to intubate a patient using endotracheal intubation tube 1, this endotracheal intubation anti-dislodgement protection mechanism can be used to secure the tube 1. First, the electromagnet 15 is activated, and the electromagnet 15 attracts the magnet 14 through its magnetism. The magnet 14 drives the first bevel gear 12 to remain in an upward state, so that the first bevel gear 12 and the second bevel gear 13 are in a meshing state. Then, the strap 201 is placed over the patient's head, the mounting plate 2 is placed at the patient's mouth position, and then the tube 1 is passed through the middle of the hollow tube 3, thereby inserting the tube 1 into the patient's body. The connector 101 is then connected to the ventilator tubing. Then, people can rotate the handle 10, which drives the winding rod 9 to rotate. The first torsion spring 11 is twisted, and the winding rod 9 rotates to wind up the strap 201. After the strap 201 is contracted, it can tighten the patient's head, so that the mounting plate 2 is in close contact with the patient's mouth. At the same time, the rotation of the winding rod 9 will drive the first bevel gear 12 to rotate, which in turn drives the second bevel gear 13 to rotate. The rotation of the second bevel gear 13 will drive the right threaded rod 8 to rotate, which will cause the extrusion tube 5 to move backward. When the extrusion tube 5 moves backward and contacts the first wedge block 6, it will push the first wedge block 6 to move backward. A wedge-shaped block 6 moves towards a side closer to the other side, causing the clamping block 4 to move towards the other side. The clamping block 4 clamps the conduit 1, compressing the first spring 7. When the pressure sensor 151 contacts the outer wall of the conduit 1 and detects a pressure value greater than the rated value, it sends an electrical signal to the electromagnet 15, causing the electromagnet 15 to automatically shut off. The first bevel gear 12 and the magnet block 14 then move downwards due to gravity, separating the first bevel gear 12 and the second bevel gear 13. In this way, the winding lever 9 can continue to be rotated to wind up the conduit. Once the bandage 201 is tightly secured to the patient's head, the rotation of the retractor 9 can be stopped. A locking mechanism restricts the position of the retractor 9, preventing it from automatically reversing and loosening the bandage 201 after it is released. At this time, the threaded rod 8 on the right stops rotating. Therefore, after the clamping block 4 clamps the catheter 1, it can automatically stop the squeezing tube 5 from moving, causing the clamping block 4 to stop automatically. The retractor 9 will continue to rotate and tighten the bandage 201, which can prevent the retractor 9 from continuously rotating, causing the clamping block 4 to continuously clamp the catheter 1 and making it impossible to clamp catheters 1 of different diameters.

[0027] When the conduit 1 needs to be disassembled after use, the winding rod 9 is released through the locking mechanism. Under the action of the first torsion spring 11, the winding rod 9 is driven to reverse and reset, and the winding rod 9 releases the strap 201. In this way, the strap 201 can be automatically loosened. Then, people manually rotate the right threaded rod 8 in the opposite direction. The right threaded rod 8 reverses and drives the extrusion tube 5 to move forward and separate from the first wedge block 6. At this time, under the action of the first spring 7, the clamping block 4 and the first wedge block 6 move to the side away from each other and reset to release the conduit 1. After the pressure sensor 151 and the conduit 1 are separated, the electromagnet 15 is energized. The electromagnet 15 attracts the magnet block 14. The magnet block 14 drives the first bevel gear 12 to move upward and reset to re-engage with the second bevel gear 13. People can then remove the conduit 1.

[0028] When people rotate the take-up lever 9, the rotation of the take-up lever 9 drives the ratchet 16 to rotate. The rotation of the ratchet 16 intermittently squeezes the ratchet 17. After being squeezed by the ratchet 16, the ratchet 17 swings to the left, and the second torsion spring 19 is twisted. When the ratchet 16 and the ratchet 17 are separated, the action of the second torsion spring 19 drives the ratchet 17 to reverse and reset. The abutment block 18 will then abut against the ratchet 17 to prevent the ratchet 17 from swinging to the right, thus preventing the ratchet 16 from rotating in the opposite direction and preventing the take-up lever 9 from reversing and loosening the strap 201. When people need to loosen the strap 201, they can manually move the pressure frame 20 downward. The downward movement of the pressure frame 20 drives the ratchet 17 downward and separates it from the ratchet 16, thus loosening the take-up lever 9 and loosening the strap 201. After the strap 201 is loosened, the pressure frame 20 can be manually pulled upward to reset, and the ratchet 17 re-engages with the ratchet 16.

[0029] Example 2 Based on Example 1, such as Figure 4 As shown, it also includes a bevel gear set 21, a twisted shaft 22, and a meshing plate 23. The twisted shaft 22 is rotatably connected to the left side of the mounting plate 2. The meshing plate 23 is slidably connected to both the upper and lower sides of the rear part of the mounting plate 2. The meshing plate 23 and the twisted shaft 22 are threadedly connected. The bevel gear set 21 is connected between the rear part of the threaded rod 8 on the left and the twisted shaft 22. The bevel gear set 21 consists of two bevel gears. One bevel gear is connected to the rear part of the threaded rod 8 on the left, while the other bevel gear is fixedly connected to the twisted shaft 22.

[0030] The catheter 1 is inserted into the patient's body through the middle of the hollow tube 3. The patient's teeth should be kept away from the catheter 1. However, if the patient is conscious, they may involuntarily bite the catheter 1. If the catheter 1 is flattened, it can easily affect the patient's breathing. Therefore, this embodiment includes an occlusal plate 23. The patient's teeth can fit snugly against the outer wall of the occlusal plate 23, preventing the patient from biting the catheter 1. Furthermore, since the diameter of the catheter 1 used is not uniform, the gap between the occlusal plates 23 also needs to be adjusted according to the diameter of the catheter 1. If a small-diameter catheter 1 is used, and the gap between the occlusal plates 23 is very large, the patient's mouth will remain wide open, making it easier for foreign objects to enter. Entering the patient's mouth affects the patient's breathing. Therefore, when the squeezing tube 5 moves backward, it will drive the threaded rod 8 on the left to rotate. The rotation of the threaded rod 8 on the left drives the bevel gear set 21 to rotate, which in turn drives the twisted shaft 22 to rotate. The rotation of the twisted shaft 22 then drives the occlusal plates 23 to move closer to each other. After the squeezing tube 5 stops, the occlusal plates 23 also stop moving. The gap between the occlusal plates 23 is just enough to accommodate the catheter 1. When the squeezing tube 5 moves forward, the forward movement of the squeezing tube 5 drives the threaded rod 8 to reverse. The reverse movement of the threaded rod 8 drives the bevel gear set 21 to reverse. The reverse movement of the bevel gear set 21 drives the occlusal plates 23 to move and reset to the side away from each other.

[0031] like Figure 1 , Figure 5 As shown, it also includes a support plate 231, a mounting base 24, a second wedge block 25, a second spring 26, and a telescopic rod 27. The support plate 231 is fixedly connected to the bottom of the mounting plate 2. The mounting base 231 is connected to the left and right sides of the front part of the support plate 231. The mounting base 24 is used to hold the connector 101. The second wedge block 25 is slidably connected to the front and rear sides of the upper part of the mounting base 24. The second spring 26 is connected between the second wedge block 25 and the mounting base 24. The telescopic rod 27 is connected to the front and rear sides of the upper part of the mounting base 24. The second spring 26 is sleeved on the outside of the telescopic rod 27. The end of the telescopic rod 27 is fixedly connected to the second wedge block 25.

[0032] like Figure 2 and Figure 5 As shown, it also includes an inclined frame 28, a column 29, a lower pressure frame 30, and a third spring 31. An inclined frame 28 is fixedly connected to the second wedge block 25. A lower pressure frame 30 is slidably connected inside the mounting plate 2. The lower pressure frame 30 and the pressing frame 20 are fixedly connected. A third spring 31 is connected between the upper left and right sides of the lower pressure frame 30 and the top of the mounting plate 2. Two columns 29 are connected to the front left and right sides of the lower pressure frame 30. The columns 29 and the lower part of the inclined frame 28 are pressed together.

[0033] After connecting connector 101 to the ventilator tubing, in order to fix the position of connector 101 and improve the connection strength between connector 101 and ventilator tubing, the present invention provides the following solution: When medical staff insert connector 101 into the retainer 24, the second wedge block 25 will move outward after contact between connector 101 and the second wedge block 25, compressing the second spring 26 and the telescopic rod 27. When connector 101 and the second wedge block 25 separate, the second spring 26 and the telescopic rod 27 will cause the second wedge block 25 to move inward and reset, holding the top of connector 101 in place to prevent separation of connector 101 and retainer 24, thus restricting connector 101. When catheter 1 is removed, pressing down on the pressure bracket 30 will compress the third spring 31, causing the pressure bracket 30 to move downward simultaneously. The pressure frame 20 and column 29 move downwards, causing the strap 201 to be loosened. At the same time, the column 29 presses against the inclined surface of the inclined frame 28, causing the inclined frame 28 to move outwards. This causes the second wedge block 25 to move outwards and separate from the connector 101, thus allowing the connector 101 to be removed from the card holder 24. After that, when the lower pressure frame 30 is released, the third spring 31 causes the lower pressure frame 30 to move upwards and reset. The lower pressure frame 30 causes the pressure frame 20 and column 29 to move upwards and reset. At this time, under the action of the second spring 26 and the telescopic rod 27, the second wedge block 25 moves inwards and resets.

[0034] like Figure 5 As shown, it also includes an ejector 32 and a fourth spring 33. The ejector 32 is slidably connected inside the card holder 24, and the fourth spring 33 is connected between the bottom of the ejector 32 and the card holder 24.

[0035] When the connector 101 is inserted between the card holders 24, the connector 101 pushes the ejector 32 downward, and the fourth spring 33 is stretched. When the second wedge block 25 releases the connector 101, the ejector 32 moves upward under the action of the fourth spring 33, pushing the connector 101 upward so that the connector 101 can be removed.

[0036] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention. Therefore, the scope of the invention should be limited only by the appended claims.
