Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a disposable intubation fixation device. Background Technology

[0002] In medical practice, intubation procedures, such as endotracheal intubation and gastric tube insertion, are frequently required to maintain patients' breathing, nutritional supply, or to perform other necessary medical interventions. However, the issue of securing the tubes after intubation remains a challenge for healthcare professionals. Traditional methods, such as using tape or bandages to directly wrap around the tube and the patient's skin, not only provide poor fixation but may also damage the patient's skin and increase the risk of infection. Utility Model Content

[0003] This invention provides a novel, easy-to-use, and effective disposable cannula fixation device, aiming to provide a solution that can safely and stably fix the cannula while reducing discomfort or damage to the patient's skin.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is:

[0005] To achieve the above objectives, this utility model discloses a disposable cannula fixation device, comprising:

[0006] A base, wherein the base is provided with a mounting groove and at least two through holes, and each through hole is spaced apart from the mounting groove;

[0007] Mounting base, the mounting base is mounted on the base and the mounting base is located in the mounting groove, the mounting base is provided with a tube installation port;

[0008] An intermediate connecting tube is provided, the first end of which is installed on the mounting base and is coaxially arranged with the insertion port. A clearance groove is provided on the side wall of the first end of the intermediate connecting tube, and an external thread is provided on the second end of the intermediate connecting tube.

[0009] At least two control sliders, each of which is slidably connected to the mounting base and is located within the clearance groove;

[0010] The control ring has an inner diameter at its first end that gradually increases in the direction toward the mounting base, and an internal thread at its second end that engages with the external thread.

[0011] A connecting strap, the two ends of which are respectively connected to the base;

[0012] When the control ring moves toward the mounting base, the first end of the control ring pushes each of the control sliders to move radially inward along the insertion port.

[0013] The disposable cannula fixation device disclosed in this embodiment achieves rapid and stable fixation of the cannula through the cooperation of the control ring and the control slider, which improves the safety and reliability of medical operations. In addition, its structure is simple and easy to operate, making it suitable for single use, reducing the risk of cross-infection and improving medical efficiency.

[0014] Optionally, it also includes filler blocks, with each filler block disposed between two adjacent control sliders, and the inner diameter of the ring formed by each filler block is equal to the diameter of the cannula installation port.

[0015] By designing a filler block, gaps are avoided between the insertion port and the intermediate connecting pipe, making insertion installation more convenient and preventing the end of the insertion pipe from getting stuck in the gap. This achieves the goal of rapid insertion installation. The filler block design not only fills the gaps between the control sliders but also enhances the stability and fixation of the device.

[0016] Optionally, the first end of the intermediate connecting pipe is provided with a plurality of clearance grooves, and the plurality of clearance grooves are provided in a one-to-one correspondence with the plurality of control sliders.

[0017] The clearance groove provides sufficient movement space for the control slider, allowing it to move smoothly in the radial direction of the cannula mounting port. The cooperation between the clearance groove and the control slider enables more even and stable clamping of the cannula. This flexibility ensures that the control slider responds quickly and accurately when pushed by the control ring, achieving clamping or releasing operations on the cannula, thereby improving the fixation effect.

[0018] Optionally, each of the control sliders is symmetrically arranged along the center of the cannula installation port.

[0019] When the control rings push the control sliders inward, their symmetrical distribution along the center of the cannula mounting port allows for more even clamping of the cannula, thus improving the fixation effect. This design helps prevent the cannula from shifting or falling off during use.

[0020] Optionally, the device further includes multiple springs, each corresponding to one of the control sliders. The two ends of each spring act on the mounting base and the control slider, respectively, and the springs drive the control sliders to move radially outward along the insertion port.

[0021] The introduction of the spring element provides an automatic reset function for the control slider. When the control ring is released or removed, the spring element immediately drives the control slider to move radially outward along the cannula insertion port, returning it to its initial state. This automatic reset function simplifies the operation process, eliminating the need for medical personnel to manually adjust the position of the control slider and improving work efficiency. The presence of the spring element allows the control slider to maintain a certain degree of elasticity when subjected to external forces, thus better adapting to changes in the shape and size of the cannula.

[0022] Optionally, it also includes a fixing nut, which is threaded to the second end of the intermediate connecting tube, and the fixing nut is located on the side of the control ring away from the mounting base.

[0023] The retaining nut is securely fastened to the second end of the intermediate connecting tube via a threaded connection, providing an additional fixing point for the entire device. This design enhances the connection stability between the intermediate connecting tube and the control ring, reducing the risk of loosening or detachment due to vibration or external forces.

[0024] Optionally: The base includes a first seat and a second seat that are detachably connected. The first seat is provided with a first arc-shaped groove, and the second seat is provided with a second arc-shaped groove. The second arc-shaped groove is opposite to the opening of the first arc-shaped groove to form the mounting groove. The mounting seat is detachably engaged with the mounting groove. The first seat and the second seat are respectively connected to both ends of the connecting strap.

[0025] By designing the base as a detachable first and second seat, medical staff can easily install or disassemble the entire base structure. Separating the first and second seats allows the base structure to be separated from the mounting base, facilitating full exposure of the patient's oral cavity and enabling medical staff to observe the patient's mouth or perform other medical procedures.

[0026] Optionally: The mounting base is provided with a first connecting part on each side, and the first base body and the second base body are each provided with a second connecting part for cooperating with the first connecting part. The second connecting part cooperates with the first connecting part so that the first base body and the second base body are respectively connected to the mounting base.

[0027] After the first and second seats are connected to the mounting base respectively, the first and second seats and the connecting strap can fix the mounting base and the insertion tube therein, thereby preventing the insertion tube from moving at will.

[0028] Optionally, one of the first connecting part and the second connecting part is a slot, and the other is a plug-in block for engaging with the slot.

[0029] For example, a slot can be provided on each of the opposite sides of the mounting base, and a plug-in block can be provided in each of the first and second arc-shaped slots. When the plug-in block is inserted into the slot, the first and second base bodies are connected to the mounting base. Of course, in other embodiments, it is also possible to provide a slot in each of the first and second arc-shaped slots, and then provide a plug-in block on each of the opposite sides of the mounting base. The engagement of the plug-in block and the slot also makes disassembly and reassembly more convenient.

[0030] Optionally, the mounting base is provided with a switch baffle, the first end of the switch baffle is rotatably connected to the mounting base, and the second end of the switch baffle is engaged with the mounting base, so as to control the opening or closing of the through hole when the switch baffle rotates.

[0031] The design of controlling the opening or closing of the through-hole by rotating a switch baffle is generally simpler than traditional plug-in, screw-type, or other complex mechanical structures. Users can quickly open or close the through-hole by simply rotating the baffle, greatly improving operational efficiency. The rotating connection and snap-fit ​​design makes the overall structure more compact, reducing space occupation. This is especially important for space-constrained devices or applications, helping to achieve smaller size and higher integration.

Detailed Implementation

[0047] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0048] Example:

[0049] See Figures 1 to 11 This utility model discloses a disposable cannula fixing device, which includes a base 800, a mounting base 100, an intermediate connecting tube 200, at least two control sliders 300, a control ring 400, and a connecting strap 500. The base 800 is provided with a mounting groove and at least two through holes 810, each through hole spaced apart from the mounting groove 810. The mounting base 100 is mounted on the base 800 and located within the mounting groove. The mounting base 100 is provided with a cannula mounting port 110. The first end of the intermediate connecting tube 200 is mounted on the mounting base 100, and the intermediate connecting tube 200 is coaxially arranged with the cannula mounting port 110. A clearance groove 210 is provided on the side wall of the first end of the intermediate connecting tube 200, and the second end of the intermediate connecting tube 200 is provided with an external thread. Each control slider 300 is slidably connected to the mounting base 100, and the control slider 300 is located within the clearance groove 210. The inner diameter of the first end of the control ring 400 gradually increases in the direction toward the mounting base 100, and the second end of the control ring 400 is provided with an internal thread for engaging with the external thread. The two ends of the connecting band 500 are respectively connected to the base 800. When the control ring 400 moves toward the mounting base 100, the first end of the control ring 400 pushes each control slider 300 to move radially inward along the insertion port 110.

[0050] The connecting strap can be set as an elastic bandage, or it can be divided into two sections, which are connected in a detachable manner by means of buckles or adhesive.

[0051] The disposable intubation cannula fixation device disclosed in this embodiment achieves rapid and stable fixation of the intubation cannula 1000 through the cooperation of the control ring 400 and the control slider 300, improving the safety and reliability of medical operations. Its simple structure and convenient operation make it suitable for single use, reducing the risk of cross-infection and improving medical efficiency. The through-hole 810 design allows medical staff to easily clear oral secretions from the patient, ensuring patient comfort and maintaining a clear airway.

[0052] In one embodiment, the disposable cannula fixing device further includes filler blocks 900. Filler blocks 900 are disposed between each pair of adjacent control sliders 300, and the inner diameter of the ring formed by the filler blocks 900 is equal to the diameter of the cannula mounting port 110. By designing the filler blocks 900, gaps between the cannula mounting port 110 and the intermediate connecting tube 200 are avoided, making the installation of the cannula 1000 more convenient and preventing the end of the cannula 1000 from getting stuck in the gap between the cannula mounting port 110 and the intermediate connecting tube 200, thereby achieving the purpose of rapid installation of the cannula 1000. The design of the filler blocks 900 not only fills the gaps between the control sliders 300 but also enhances the stability and fixing effect of the device.

[0053] In one embodiment, the outer diameter of the ring formed by the filling blocks 900 is equal to the inner diameter of the intermediate connecting tube 200. When the filling blocks 900 are closely arranged to form a ring with the same inner diameter as the intermediate connecting tube 200, they not only fill the gaps between the control sliders 300, but also provide a continuous and stable support structure for the entire device. The close fit between the filling blocks 900 and the inner wall of the intermediate connecting tube 200 reduces wobbling or displacement caused by gaps, further enhancing the fixation effect of the cannula 1000. This is particularly important for medical procedures that require maintaining the cannula 1000 in a stable position for extended periods, effectively reducing the risks and discomfort caused by cannula 1000 displacement. This represents a significant improvement in comfort for patients who need to wear the cannula fixation device for extended periods.

[0054] In one embodiment, the first end of the intermediate connecting tube 200 is provided with a plurality of clearance grooves 210, each corresponding to a plurality of control sliders 300. The clearance grooves 210 provide sufficient movement space for the control sliders 300, allowing them to move smoothly in the radial direction of the insertion port 110. Through the cooperation of the clearance grooves 210 and the control sliders 300, a more uniform and stable clamping of the insertion tube 1000 can be achieved. This flexibility ensures that the control sliders 300 can respond quickly and accurately when pushed by the control ring 400, enabling clamping or releasing operations on the insertion tube 1000, thereby improving the fixation effect.

[0055] In one embodiment, each control slider 300 is symmetrically arranged around the central cannula mounting port 110.

[0056] When the control ring 400 pushes the control slider 300 inward, the cannula 1000 is clamped more evenly because they are symmetrically distributed along the center of the cannula mounting port 110, thereby improving the fixation effect. This design helps prevent the cannula 1000 from shifting or falling off during use.

[0057] In one embodiment, the disposable cannula fixing device further includes multiple spring members, which are arranged one-to-one with multiple control sliders 300. The two ends of the spring members act on the mounting base 100 and the control sliders 300 respectively, and the spring members are used to drive the control sliders 300 to move radially outward along the cannula mounting port 110.

[0058] The introduction of the spring element provides the control slider 300 with an automatic reset function. When the control ring 400 is released or removed, the spring element immediately drives the control slider 300 to move radially outward along the cannula mounting port 110, returning it to its initial state. This automatic reset function simplifies the operation process, eliminating the need for medical personnel to manually adjust the position of the control slider 300 and improving work efficiency. The presence of the spring element allows the control slider 300 to maintain a certain degree of elasticity when subjected to external forces, thereby better adapting to changes in the shape and size of the cannula 1000.

[0059] In one embodiment, the disposable cannula fixing device further includes a fixing nut 600, which is threadedly connected to the second end of the intermediate connecting tube 200, and is located on the side of the control ring 400 opposite to the mounting base 100. The fixing nut 600 is tightly secured to the second end of the intermediate connecting tube 200 via a threaded connection, providing an additional fixing point for the entire device. This design enhances the connection stability between the intermediate connecting tube 200 and the control ring 400, reducing the risk of loosening or detachment due to vibration or external forces.

[0060] In one embodiment, the mounting base 100 is encased in a sponge. The sponge absorbs and disperses pressure from the device on the patient's skin, reducing pressure concentration at local pressure points and thus lowering the risk of skin damage or pressure sores. This is particularly important for patients who need to wear intubation fixation devices for extended periods, helping to protect their skin health. The sponge enclosure also increases friction between the device and the skin, making the device less prone to slipping or moving. The sponge also provides sound insulation and shock absorption, reducing the impact of external noise and vibration on the patient. This is especially important in medical settings where a quiet environment is required or vibration must be avoided, helping to provide a more comfortable and quiet treatment environment for the patient. Furthermore, the sponge can be ergonomically designed to better fit the face, and the material can absorb frequently drooling saliva and other secretions from the patient.

[0061] In one embodiment, the outer wall of the control ring 400 is provided with anti-slip texture. The anti-slip texture increases the friction between the healthcare worker's fingers and the outer wall of the control ring 400, preventing operational errors caused by slippage when rotating or pushing the control ring 400. This design helps ensure that healthcare workers can operate the control ring 400 accurately and stably under stress or emergency conditions, thereby improving operational safety.

[0062] In one embodiment, the base 800 includes a first seat body 820 and a second seat body 830 that are detachably connected. The first seat body 820 is provided with a first arc-shaped groove 821, and the second seat body 830 is provided with a second arc-shaped groove 831. The second arc-shaped groove 831 and the first arc-shaped groove 821 are opposite to each other to form a mounting groove. The mounting seat and the mounting groove are detachably engaged. The first seat body 820 and the second seat body 830 are respectively connected to both ends of the connecting strap.

[0063] By designing the base 800 as a detachable first seat 820 and second seat 830, medical staff can easily install or disassemble the entire base 800 structure. When the first seat 820 and the second seat 830 are separated, the base 800 structure can be separated from the mounting base, which helps to fully expose the patient's oral cavity, making it easier for medical staff to observe the patient's oral cavity or perform other medical procedures.

[0064] In one embodiment, a first connecting portion is provided on each side of the mounting base, and a second connecting portion is provided on both the first base body 820 and the second base body 830 for cooperating with the first connecting portion. The second connecting portion cooperates with the first connecting portion to connect the first base body 820 and the second base body 830 to the mounting base respectively.

[0065] After the first base 820 and the second base 830 are connected to the mounting base respectively, the first base 820, the second base 830 and the connecting strap can fix the mounting base and the insertion tube 1000 therein, thereby preventing the insertion tube 1000 from moving at will.

[0066] In one embodiment, one of the first connecting part and the second connecting part is a slot, and the other is a plug block for engaging with the slot.

[0067] For example, a slot can be provided on each of the opposite sides of the mounting base, and a plug-in block can be provided in the first arc-shaped groove 821 and the second arc-shaped groove 831 respectively. When the plug-in block is inserted into the slot, the first base 820 and the second base 830 are connected to the mounting base. Of course, in other embodiments, it is also possible to provide a slot in each of the first arc-shaped groove 821 and the second arc-shaped groove 831, and then provide a plug-in block on each of the opposite sides of the mounting base. The engagement of the plug-in block and the slot also makes disassembly more convenient.

[0068] In one embodiment, a flexible tube 840 for protecting the intubation cannula 1000 is provided behind the base 800. The flexible tube 840 is sleeved over the intubation cannula 1000. When the patient bites on the flexible tube 840, it can prevent damage to the intubation cannula 1000. At the same time, the flexible tube 840 is resilient, so that if the patient deforms the flexible tube 840 and the intubation cannula 1000 by biting, the flexible tube 840 can quickly return to its shape, thereby preventing blockage of the intubation cannula 1000.

[0069] In one embodiment, a switch baffle 700 is provided on the mounting base 100. The first end of the switch baffle 700 is rotatably connected to the mounting base 100, and the second end of the switch baffle 700 is snapped into the mounting base 100. When the switch baffle 700 rotates, it controls the through hole 810 to open or close.

[0070] The opening and closing of the through-hole 810 is controlled by rotating the switch baffle 700. This design is generally simpler than traditional plug-in, screw-type, or other complex mechanical structures. Users can quickly open or close the through-hole 810 by simply rotating the baffle, greatly improving operational efficiency. The rotating connection and snap-fit ​​design makes the overall structure more compact and reduces space occupation. This is especially important for space-constrained devices or applications, helping to achieve smaller size and higher integration.

[0071] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
