Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to an anti-slip positioning component for endotracheal tubes used in CT examinations. Background Technology
[0002] In the clinical diagnosis and treatment of critically ill patients, CT scans are the core imaging tool for assessing disease progression, screening for potential lesions, and guiding the formulation of subsequent treatment plans. These patients often suffer from respiratory failure or severe respiratory distress, and endotracheal intubation can be used to establish a ventilation pathway to maintain normal breathing and ensure the body's blood oxygen supply.
[0003] During the entire CT scan process, patient movement, bed transfers, position adjustments, and unconscious agitation or coughing can directly disrupt the intubation tube position. The weight and tension of the ventilator tubing and monitoring cables can create continuous external forces, causing the intubation tube to shift, potentially leading to accidental slippage or displacement, which directly endangers the patient's life.
[0004] Traditional tape fixation is prone to failure during patient transport due to sweating and facial oil loosening. Tape residue can also affect the observation of facial skin condition. Metal clamps or fixation devices containing metal can produce severe artifacts on CT images, and they only provide radial clamping of the trachea, resulting in poor axial tensile strength of the trachea. Summary of the Invention
[0005] The purpose of this invention is to provide an anti-slip positioning component for endotracheal intubation in CT examinations, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a face mask is included, and a radial locking component is also included. The radial locking component is disposed on the face mask. The radial locking component includes a base and a screwing component. The base is hollow, and the screwing component is annular. Bosses are evenly distributed on the inner circumference of the screwing component. Fixing claws are slidably disposed on the base and the screwing component. An axial locking component is also included, and the axial locking component is disposed on the face mask.
[0007] Furthermore, the radial locking component also includes an arc-shaped guide hole, a first guide block, a strip-shaped guide hole, and a second guide block. The arc-shaped guide hole is formed on the boss of the screwing component. The first guide block is fixed to the top of the fixing claw, and the second guide block is fixed to the bottom of the fixing claw. The strip-shaped guide hole is formed on the base. The second guide block is slidably disposed in the strip-shaped guide hole, and the first guide block is slidably disposed in the arc-shaped guide hole.
[0008] With the above scheme, the first guide block and the second guide block are fixed to the fixed claw, forming an upper and lower linkage structure of the fixed claw. The arc-shaped guide hole provides a sliding path for the first guide block, and the strip-shaped guide hole provides a guiding channel for the second guide block, forming a bidirectional sliding constraint for the fixed claw. When the screwing component is turned, the screwing component drives the arc-shaped guide hole on the boss to move synchronously. The arc-shaped guide hole generates thrust through sliding cooperation with the first guide block, pushing the fixed claw to move. At the same time, the second guide block at the bottom of the fixed claw slides along the strip-shaped guide hole, providing guidance for the fixed claw, so that multiple fixed claws move towards the insertion tube synchronously and evenly, realizing radial clamping of the insertion tube and preventing the insertion tube from shifting.
[0009] Furthermore, the end of the fixing claw is arc-shaped, and the arc-shaped end of the fixing claw has anti-slip teeth.
[0010] The above solution utilizes an arc-shaped design at the end of the fixing claw to adapt to the circular structure of the outer wall of the insertion cannula. The arc-shaped end increases the contact area between the fixing claw and the insertion cannula, reducing local pressure and lowering the risk of deformation of the outer wall of the insertion cannula. The anti-slip teeth enhance the static friction between the two, preventing relative sliding. When clamped, the arc-shaped end of the fixing claw fits tightly against the surface of the insertion cannula, and the anti-slip teeth form anti-slip resistance.
[0011] Furthermore, the axial locking component includes a guide platform, a fixed seat, a fixed plate, and an elastic plate. The end of the elastic plate away from the fixed plate is arc-shaped. The guide platform is fixed on the screwing component, the fixed seat is fixed on the base, the fixed plate is rotatably connected to the fixed seat, and the elastic plate is fixed on the fixed plate.
[0012] Through the above scheme, the guide platform and the screwing component are fixed together, and the fixed seat and base serve as the rotation fulcrum. The arc-shaped end of the elastic plate adapts to the shape of the insertion tube, increasing the contact area with the tube. The axial locking component achieves axial compression of the insertion tube, forming a double locking with the radial clamping of the radial locking component. The screwing component drives the guide platform to rotate, and the guide platform pushes the fixed plate to rotate around the fixed seat through the inclined surface. The fixed plate drives the elastic plate to rotate downward, and the arc-shaped end of the elastic plate presses against the outer wall of the insertion tube. At this time, the elastic plate generates axial pressure on the insertion tube, resisting outward pulling force. Combined with the radial fixation of the radial locking component, a double anti-slip effect is formed, which is suitable for scenarios where patients move or tubes are entangled during CT examinations.
[0013] Furthermore, the mask includes a mask body, ear loops, and a connecting end. The ear loops are fixed to the side of the mask body, and the connecting end is fixed to the front of the mask body. The inner contour of the mask body conforms to the curve of the patient's cheek.
[0014] The above design ensures the mask fits snugly against the cheeks for easy fixation of subsequent components. The ear loops connect to the straps, and the connecting ends provide a mounting base for the radial locking components. The mask conforms to the patient's cheeks, and its inner contour adapts to the facial curves, increasing the contact area and reducing skin pressure. The straps pass through the ear loops and are secured to the head, preventing the mask from easily loosening.
[0015] Furthermore, the mask also includes a flexible strip and an observation window. The flexible strip is fixed to the edge of the mask body, and the observation window is located on the connecting end.
[0016] The above solution secures the flexible strip to the edge of the mask using a flexible medical material, while the observation window is made of transparent material. The flexible strip improves the fit and comfort between the mask and the face, reducing skin friction. The observation window facilitates observation of the intubation status. The flexible strip fills the gap between the mask and the face, and the flexible material reduces pressure and friction on the skin from the edges. Medical staff can directly observe the intubation status through the observation window.
[0017] Furthermore, the base is fixed to the connecting end.
[0018] The above solutions involve bonding, threading, or snap-fitting between the base and the connecting end.
[0019] Furthermore, the elastic plate is made of rubber.
[0020] The above solution utilizes medical-grade rubber, which is elastic, wear-resistant, and non-irritating. The elastic plate is bonded to the fixation plate. The rubber material increases friction with the cannula, improving axial fixation. When the fixation plate presses the elastic plate against the cannula, the rubber's elastic deformation increases the contact area, enhancing static friction, strengthening axial restraint, and resisting the force that pulls the cannula out.
[0021] The radial locking component includes a circular retainer located in the center of the base. The retainer has radially retractable arc-shaped claws evenly distributed along its inner circumference. The inner walls of the claws have anti-slip teeth, and the tails of the claws are connected to inclined sliders. It also includes a rotating sleeve coaxially sleeved outside the retainer. The inner wall of the knob has an inner conical surface or a spiral inclined surface track that mates with the inclined sliders at the tails of the claws. When the knob is rotated clockwise, the inner conical surface pushes all the inclined sliders to retract synchronously inward, causing all the claws to radially close, thus evenly gripping the endotracheal tube. Rotating counterclockwise loosens the locking mechanism.
[0022] The axial locking component includes an elastic pressure plate (made of silicone or flexible plastic) located in front of the pawl, one end of which is hinged to the base. The pressure plate is linked to the locking knob via a linkage or cam mechanism. When the knob is rotated to lock the radial pawl, the linkage mechanism synchronously drives the elastic pressure plate to rotate downward, pressing down on the insertion tube and forming an axial constraint to prevent the insertion tube from sliding back and forth. When unlocking, the pressure plate automatically springs up.
[0023] In use, attach the base to the appropriate position above the patient's upper lip → place the endotracheal tube in the closed jaws and pass it under the pressure plate → rotate the locking knob clockwise about half a turn to one turn. When rotating the knob, two mechanical actions occur simultaneously: radial locking: the inner conical surface of the knob pushes the inclined sliders of all the jaws, causing the jaws to contract synchronously and evenly towards the center, gripping the tube tightly, with the anti-slip teeth providing static friction. Axial locking: through a linkage mechanism (such as a cam on the knob driving a connecting rod), the elastic pressure plate is pushed against the tube, creating downward pressure to effectively resist the force that pulls the tube outward. When adjusting the tube depth, rotate the knob counterclockwise slightly; the pressure plate first lifts to release the axial pressure, and continued rotation causes the jaws to loosen radially, allowing the tube to move smoothly. After adjustment, retighten the knob. The entire process can be completed with one hand.
[0024] The dual mechanical locking system, combining radial clamping and axial compression, provides excellent securing force. The entire structure is made of non-metallic materials, eliminating metal artifacts. Operation is efficient and safe: a knob-type operation allows for rapid locking and unlocking. It can be quickly unlocked in emergencies. No tape is required, avoiding skin damage.
[0025] The technical effects and advantages of this invention are as follows:
[0026] 1. When the screwing component of this invention is tightened, the screwing component will drive the guide table to rotate. The fixed seat will push the fixed plate and the elastic plate to rotate on the fixed seat through its inclined surface, thereby causing the elastic plate to form downward pressure, effectively resisting the force of the insertion tube being pulled outward. The screwing component can also drive the fixed claw to move axially on the base. The radial fixation of the insertion tube can be achieved by multiple mutually close fixed claws. This device provides good fixing force through the dual mechanical locking of radial clamping and axial pressing. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0039] This invention provides, for example Figures 1 to 7 The image shows an anti-slip positioning component for endotracheal tubes used in CT scans.
[0040] Example 1:
[0041] The device includes a face mask 1, which comprises a mask body 101, ear loops 102, and a connecting end 104. The ear loops 102 are fixed to the side of the mask body 101, and the connecting end 104 is fixed to the front of the mask body 101. The inner contour of the mask body 101 conforms to the curve of the patient's cheek, facilitating the fixation of subsequent components. The ear loops 102 connect to straps, and the connecting end 104 provides a mounting base for the radial locking component 2. The mask body 101 conforms to the patient's cheek, and its inner contour adapts to the facial curve, increasing the contact area and reducing skin pressure. The straps pass through the ear loops 102 and are fixed to the head, making the mask body 101 less prone to loosening.
[0042] The mask 1 also includes a flexible strip 103 and an observation window 105. The flexible strip 103 is fixed to the edge of the mask body 101, and the observation window 105 is located on the connecting end 104. The flexible strip 103 is fixed to the edge of the mask body 101 and is made of flexible medical material, while the observation window 105 is made of transparent material. The flexible strip 103 improves the fit and comfort of the mask body 101 to the face and reduces skin friction. The observation window 105 facilitates observation of the intubation status. The flexible strip 103 fills the gap between the mask body 101 and the face, and the flexible material reduces pressure and friction on the skin from the edges. Medical personnel can directly observe the insertion status of the intubation device through the observation window 105.
[0043] It also includes a radial locking component 2, which is disposed on the mask 1. The radial locking component 2 includes a base 201 and a screwing component 202. The base 201 is hollow, and the screwing component 202 is annular. The screwing component 202 has protrusions evenly distributed in the inner circumference. The base 201 is fixed to the connecting end 104. The base 201 and the connecting end 104 are connected by adhesive, threaded connection or snap-fit connection.
[0044] A fixing claw 203 is slidably disposed on the base 201 and the screwing component 202. The radial locking component 2 also includes an arc-shaped guide hole 204, a first guide block 205, a strip-shaped guide hole 206, and a second guide block 207. The arc-shaped guide hole 204 is opened on the boss of the screwing component 202. The first guide block 205 is fixed to the top of the fixing claw 203, and the second guide block 207 is fixed to the bottom of the fixing claw 203. The strip-shaped guide hole 206 is opened on the base 201. The second guide block 207 is slidably disposed in the strip-shaped guide hole 206, and the first guide block 205 is slidably disposed in the arc-shaped guide hole 204. The first guide block 205 and the second guide block 207 are respectively fixed to the fixing claw 203, forming an upper and lower linkage structure of the fixing claw 203. The arc-shaped guide hole 204 provides a sliding path for the first guide block 205, and the strip-shaped guide hole 206 provides a guiding channel for the second guide block 207, forming a bidirectional sliding constraint of the fixing claw 203. When the screwing component 202 is turned, the screwing component 202 drives the arc-shaped guide hole 204 on the boss to move synchronously. The arc-shaped guide hole 204 generates thrust through sliding cooperation with the first guide block 205, pushing the fixing claw 203 to move. At the same time, the second guide block 207 at the bottom of the fixing claw 203 slides along the strip guide hole 206 to provide guidance for the fixing claw 203, so that multiple fixing claws 203 move towards the insertion tube synchronously and evenly, thereby achieving radial clamping of the insertion tube and preventing the insertion tube from shifting.
[0045] The end of the fixing claw 203 is arc-shaped and has anti-slip teeth. The arc-shaped design of the fixing claw 203 is adapted to the circular structure of the outer wall of the cannula. The arc-shaped end increases the contact area between the fixing claw 203 and the cannula, reduces local pressure, and lowers the risk of deformation of the outer wall of the cannula. The anti-slip teeth increase the static friction between the two and prevent relative sliding. When clamped, the arc-shaped end of the fixing claw 203 fits tightly against the surface of the cannula, and the anti-slip teeth form anti-slip resistance.
[0046] It also includes an axial locking component 3, which is mounted on the face shield 1. The axial locking component 3 includes a guide platform 301, a fixed base 302, a fixed plate 303, and an elastic plate 304. The end of the elastic plate 304 away from the fixed plate 303 is arc-shaped. The guide platform 301 is fixed to the screwing component 202, the fixed base 302 is fixed to the base 201, the fixed plate 303 is rotatably connected to the fixed base 302, and the elastic plate 304 is fixed to the fixed plate 303. The guide platform 301 and the screwing component 202 are fixed together to form a linkage. The fixed base 302 and the base 201 are fixed as a rotation fulcrum. The arc-shaped end of the elastic plate 304 is adapted to the shape of the insertion tube, increasing the contact area with the insertion tube. The axial locking component 3 achieves axial compression of the insertion tube, forming a double locking with the radial clamping of the radial locking component 2. The screwing component 202 drives the guide platform 301 to rotate. The guide platform 301 pushes the fixing plate 303 to rotate around the fixing seat 302 via the inclined surface. The fixing plate 303 drives the elastic plate 304 to rotate downward, and the arc-shaped end of the elastic plate 304 presses against the outer wall of the insertion tube. At this time, the elastic plate 304 generates axial pressure on the insertion tube, resisting outward pulling force. Combined with the radial fixation of the radial locking component 2, a double anti-slip effect is formed, which is suitable for scenarios where patients move or tubes are entangled during CT examinations.
[0047] The elastic plate 304 is made of rubber, specifically medical-grade rubber, which is elastic, wear-resistant, and non-irritating. The elastic plate 304 is bonded to the fixing plate 303. The rubber material increases friction with the cannula, improving axial fixation. When the fixing plate 303 drives the elastic plate 304 to press the cannula, the rubber's elastic deformation increases the contact area, enhancing static friction, strengthening axial restraint, and resisting the force that pulls the cannula out.
[0048] Example 2:
[0049] The radial locking component 2 includes a circular retainer located in the center of the base. The retainer has radially retractable arc-shaped claws evenly distributed along its inner circumference. The inner wall of the claws has anti-slip teeth, and the tail of each claw is connected to a sloping slider. It also includes a rotating sleeve coaxially sleeved outside the retainer. The inner wall of the knob has an inner conical surface or a spiral sloping surface track that mates with the sloping slider at the tail of the claw. When the knob is rotated clockwise, the inner conical surface pushes all the sloping sliders to retract synchronously inward, causing all the claws to radially close, thus evenly gripping the endotracheal tube. Rotating counterclockwise loosens the locking mechanism.
[0050] The axial locking component 3 includes an elastic pressure plate made of silicone or flexible plastic located in front of the pawl. One end of the pressure plate is hinged to the base. The pressure plate is linked to the locking knob via a linkage or cam mechanism. When the knob is rotated to lock the radial pawl, the linkage mechanism synchronously drives the elastic pressure plate to rotate downward, pressing down on the insertion tube and forming an axial constraint to prevent the insertion tube from sliding back and forth. When unlocking, the pressure plate automatically pops up.
[0051] In use, attach the base to the appropriate position above the patient's upper lip → place the endotracheal tube in the closed jaws and pass it under the pressure plate → rotate the locking knob clockwise about half a turn to one turn. When rotating the knob, two mechanical actions occur simultaneously: radial locking: the inner conical surface of the knob pushes the inclined sliders of all the jaws, causing the jaws to contract synchronously and evenly towards the center, gripping the tube tightly, with the anti-slip teeth providing static friction. Axial locking: through a linkage mechanism such as the cam on the knob, a connecting rod is driven, pushing the elastic pressure plate against the tube, creating downward pressure and effectively resisting the force that pulls the tube outward. When adjusting the tube depth, rotate the knob counterclockwise slightly; the pressure plate first lifts to release the axial pressure, and continued rotation causes the jaws to loosen radially, allowing the tube to move smoothly. After adjustment, retighten the knob. The entire process can be completed with one hand.
[0052] The dual mechanical locking system, combining radial clamping and axial compression, provides excellent fixation force. The entire structure is constructed of non-metallic materials, eliminating metal artifacts. Operation is efficient and safe: a knob-type operation allows for rapid locking and unlocking. It can be quickly unlocked in emergencies. No tape is required, avoiding skin damage. Additionally, the cannula should have graduated markings for easy observation of the insertion depth.
[0053] Working principle: First, pass the strap through the ear loop 102, then fasten the cover 101 to the patient's face and fix the cover 101 to the patient's face with the strap.
[0054] When the screwing component 202 is turned, the screwing component 202 will drive the guide table 301 to rotate. The fixed seat 302 will push the fixed plate 303 and the elastic plate 304 to rotate on the fixed seat 302 through its inclined surface, thereby making the elastic plate 304 exert downward pressure on the insertion tube, effectively resisting the force that pulls the insertion tube outward.
[0055] The screwing mechanism 202 will also drive the first guide block 205 to move through the arc-shaped guide hole 204. The first guide block 205 will cause the fixing claw 203 and the second guide block 207 to slide on the strip-shaped guide hole 206, thereby bringing the multiple fixing claws 203 closer together. The radial fixation of the cannula can be achieved by the multiple close-to-each-claw fixing claws 203.
[0056] When the elastic plate 304 presses the insertion tube, it will generate elastic deformation. When the fixed plate 303 moves to the top of the guide table 301, the reset elastic force generated by the elastic deformation of the elastic plate 304 causes the fixed plate 303 to abut against the guide table 301, thereby achieving self-locking of the screwing part 202 and preventing the screwing part 202 from resetting.
[0057] This device provides excellent securing force through a dual mechanical locking system of radial clamping and axial compression. Furthermore, the entire structure of the device is made of non-metallic materials, eliminating metal artifacts.
