Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a ventilator tubing fixing device for hospital beds. Background Technology

[0002] Endotracheal intubation is the insertion of a specially designed endotracheal tube through the mouth or nose, via the glottis, into the trachea or bronchus. It provides optimal conditions for airway patency, ventilation, oxygen supply, and airway suction, and is a crucial measure for rescuing patients with respiratory dysfunction. During endotracheal intubation, the patient's head should be tilted back, and the chin should be lifted forward and upward with both hands to open the mouth. Then, holding the laryngoscope handle with the left hand, the laryngoscope blade is inserted into the patient's mouth from the right corner of the mouth. The tongue is pushed to the left and then slowly advanced until the uvula is visible. The blade is then lifted vertically and advanced until the epiglottis is exposed. After the epiglottis is exposed, the glottis can be visualized. Once the glottis is visualized, hold the upper middle part of the catheter and enter the oral cavity from the right corner of the mouth until the catheter is close to the larynx. Then move the end of the catheter to the laryngoscope and carefully and accurately insert the tip of the catheter into the glottis. When inserting the catheter with the help of a stylet, once the tip of the catheter enters the glottis, the stylet should be removed and the catheter should be inserted into the trachea. After the intubation is completed, confirm that the catheter has entered the trachea and then properly fix it. When fixing, use traditional adhesive tape or new-style fixing tape and corresponding bite block for fixation, and apply it to the face and neck in a cross shape.

[0003] Traditional intubation fixation involves placing a bite block, slightly wider than the intubation tube, between the patient's upper and lower teeth to allow the patient to bite down and prevent them from biting the tube. Adhesive tape is then used to secure the tube to the bite block and applied in a crisscross pattern to the face and neck. This traditional fixation keeps the mouth constantly open, leading to dryness of the oral mucosa, significantly reduced saliva production, and the growth of bacteria. Furthermore, the adhesive tape directly compresses the patient's skin and corners of the mouth, causing discomfort. The combination of tape and a bite block also weakens the stability of the intubation tube, making it prone to displacement or even dislodgement.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0019] Preferably, elastic bands are fixedly installed on both sides of the mask, and the two elastic bands are connected by Velcro.

[0020] Compared with the prior art, the present invention provides a ventilator tubing fixation device for hospital beds, which has the following beneficial effects:

[0021] 1. This invention opens the channel opening by moving the baffle plate, and the adjustable ring bite allows it to be opened, thus ensuring both the channel opening and the ring bite are open. The mask is placed on the patient's face, allowing the catheter to enter the ring bite cavity through the channel opening. The ring bite is then closed, fixing the catheter inside. The mask prevents airborne bacteria and dust from contaminating the oral cavity. After the mask is installed, the adjustable ring bite position secures and protects the catheter when closed, preventing displacement or even dislodgement. Simultaneously, the ring bite... The device is designed to protect the catheter and prevent the patient from biting it, which could lead to catheter damage, deformation, or occlusion, potentially causing suffocation. After the catheter enters the ring bite, the ring bite must be closed first before the baffle can be moved to close the passage opening. If the baffle is moved to close the passage first, and then the ring bite is closed, the movable end of the ring bite will be blocked by one side of the baffle, making it impossible to fix the catheter. By adjusting the movement of the baffle and the state of the ring bite, the movement of the two is made in a certain sequence, preventing the ring bite from failing to fix the catheter.

[0022] 2. This invention, through the opening on the surface of the mask, allows a cleaning swab to be passed through the opening to clean and wipe the patient's mouth. Simultaneously, the mask's inlet and outlet valves allow the user to introduce water vapor into the patient's mouth through the inlet valve when it is too dry, keeping the mouth moist and allowing some gas to escape through the outlet valve. Conversely, when moisture accumulates in the mouth and on the inside of the mask due to temperature differences, the user introduces dry gas into the patient's mouth through the inlet valve, causing the moisture to evaporate and escape through the outlet valve, thus maintaining a certain level of humidity in the patient's mouth.

[0023] 3. This invention, through the combination of the pin and the socket, allows the baffle to be stored in the arc-shaped groove cavity when the mask is not in use. At this time, the pin on one side of the sliding plate coincides with the socket on the other side of the locking plate, thereby fixing the baffle. This ensures that the rectangular through hole is sealed when the device is not in use, preventing the air inlet valve from being contaminated. When the mask is in use, the baffle needs to fix the tube. At this time, the pin and the socket are disengaged, allowing the baffle to be in a movable state. The baffle can then be moved to expose the air inlet valve and the through-hole, thereby enabling the cleaning of the patient's oral cavity and humidity control. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a bedside ventilator tubing fixing device.

[0034] Please see Figure 1 , Figure 2 and Figure 8 A bedside ventilator tubing fixing device includes a mask 1, a tubing 2, and a fixing component 3;

[0035] A circular through hole 4 is provided at the center of the front of the mask 1, and a channel opening 5 is provided at the bottom of the front of the mask 1, which is connected to the circular through hole 4.

[0036] The fixing component 3 includes an annular bit 6 and a baffle plate 7. The annular bit 6 is located at the circular through hole 4 and is fixedly connected to the mask 1. The baffle plate 7 is slidably located at the channel opening 5 and is used for opening and closing the channel opening 5.

[0037] A cutout 8 is provided on one side of the movable end of the annular bite 6, and a baffle 7 is slidably disposed at the cutout 8, with the cutout 8 extending into the inner cavity of the annular bite 6.

[0038] The catheter 2 is fitted inside the annular bite piece 6. The catheter 2 moves from the channel opening 5 into the annular bite piece 6. After the catheter 2 enters the annular bite piece 6, the channel opening 5 is sealed by the baffle 7. At the same time, as the baffle 7 enters the incision 8, the baffle 7 contacts the catheter 2 and squeezes the catheter 2 to make it fit with the annular bite piece 6. After the baffle 7 is fully inserted into the incision 8, the baffle 7 and the incision 8 are aligned and the annular bite piece 6 is fixed.

[0039] During the specific procedure for catheter 2 intubation, tilt the patient's head back and lift the chin forward and upward with both hands to open the mouth. Then, hold the laryngoscope handle with the left hand and insert the laryngoscope blade into the patient's mouth from the right corner of the mouth. Push the tongue to the left and slowly advance the blade until the uvula is visible. Lift the blade vertically and advance it until the epiglottis is exposed. After lifting the epiglottis, the glottis can be exposed. Then, insert the middle and upper part of catheter 2 into the oral cavity from the right corner of the mouth until catheter 2 is close to the larynx. Move the end of the tube to the laryngoscope blade and accurately and gently insert the tip of catheter 2 into the glottis. When inserting the tube with the help of the stylet, after the tip of catheter 2 enters the glottis, remove the stylet and then insert catheter 2 into the trachea.

[0040] Preparations before catheter 2 insertion: The user moves the baffle 7, opening the channel 5 during movement. Since the baffle 7 is located at the incision 8, it disengages from the incision 8 during movement. When the channel 5 is fully open, the baffle 7 disengages from the incision 8, and the ring bite 6 is no longer obstructed by the baffle 7, making it adjustable. The ring bite 6 is then opened, and both the channel 5 and the ring bite 6 are open. The user then places the mask 1 on the patient's face and moves it downwards, allowing catheter 2 to move from the channel 5 towards the circular through-hole 4, and into the inner cavity of the ring bite 6. When catheter 2 is fully inserted into the ring... When the bite piece 6 is inserted into the cavity, the ring bite piece 6 is closed to fix the catheter 2 inside the ring bite piece 6. The baffle 7 moves to open the channel opening 5, and the baffle 7 moves and disengages from the incision 8, so that the ring bite piece 6 can move and open, which facilitates the installation of the mask 1 after the catheter 2 is placed. The mask 1 can effectively prevent bacteria and dust in the air from contaminating the oral cavity. After the mask 1 is installed, the state of the ring bite piece 6 can be adjusted so that when the ring bite piece 6 is closed, it can fix and protect the catheter 2, preventing the catheter 2 from changing position or even dislodging. At the same time, the ring bite piece 6 protects the catheter 2 to prevent the patient from biting the catheter 2, which could lead to damage to the catheter 2, deformation or blockage of the catheter 2, and thus suffocation.

[0041] After the conduit 2 is fixed inside the annular bite 6, the baffle 7 is moved towards the channel opening 5. As the baffle 7 moves towards the channel opening 5, the side of the baffle 7 closest to the annular bite 6 enters the incision 8. When the baffle 7 moves to completely close the channel opening 5, the side of the baffle 7 closest to the annular bite 6 is simultaneously located within the incision 8. Because the baffle 7 is located within the incision 8, it locks the annular bite 6, thus preventing the annular bite 6 from moving. Simultaneously, the portion of the baffle 7 located within the incision 8 interacts with the conduit. 2. Contact is made, and the tube 2 is held in place and secured within the annular bite 6 to stabilize the section of the tube 2 from the annular bite 6 to the lung. As the baffle 7 moves toward the passage opening 5, the side of the baffle 7 closest to the annular bite 6 moves along the incision 8, causing one side of the baffle 7 to move into the inner cavity of the annular bite 6. When the baffle 7 is fully inside the closed passage opening 5, because the annular bite 6 has an annular outer circumference, as the baffle 7 moves from one end of the incision 8 to the middle of the incision 8, one side of the baffle 7 gradually approaches the annular bite. At the center of the 6, the baffle 7, when moving from one end of the incision 8 to the middle of the incision 8, first contacts the catheter 2, then pushes the catheter 2 towards the inner lumen of the ring bite 6 away from the baffle 7, so that the outer periphery of the catheter 2 is tightly attached to the inner wall of the ring bite 6, thereby further fixing the catheter 2. This ensures that when the section of the catheter 2 outside the mask 1 moves, the section of the catheter 2 inside the mask 1 and extending into the patient's body remains stable. At the same time, the sliding cooperation between the baffle 7 and the incision 8 not only fixes the catheter 2, but also ensures that after the catheter 2 enters the ring bite 6, the ring bite 6 must be closed first before the baffle 7 can be moved to close the channel opening 5. If the baffle 7 is moved first to close the channel 5, and then the ring bite 6 is closed, the movable end of the ring bite 6 will be blocked against one side of the baffle 7, thus failing to fix the catheter 2. Through the movement of the baffle 7 and the adjustment of the state of the ring bite 6, the movement states of the two have a certain sequence, avoiding the ring bite 6 failing to fix the catheter 2.

[0042] Further, see Figure 3 For the aforementioned annular biting member 6, the annular biting member 6 includes a fixed half ring 61 and a movable half ring 62. The cutout 8 is opened on the movable ring plate 62. One end of the fixed half ring 61 is provided with an inner groove 63. One end of the movable half ring 62 is provided with a sliding block 64. The sliding block 64 is slidably disposed in the inner cavity of the inner groove 63. A guide rod is fixedly disposed in the inner cavity of the inner groove 63. The movable half ring 62 is sleeved on the outer periphery of the guide rod. A first spring 65 is provided on one side of the sliding block 64. The first spring 65 is sleeved on the outer periphery of the guide rod.

[0043] When the movable half-ring 62 and the fixed half-ring 61 are in contact end to end, they form a cylindrical shape. When the sliding block 64 moves towards the opening of the inner groove 63, the movable half-ring 62 moves outward from the inner groove 63. When the sliding block 64 moves to the inner groove 63 near the opening, the movable half-ring 62 and the fixed half-ring 61 are in contact end to end, forming a cylindrical annular bite 6, which fixes and protects the conduit 2 inside the annular bite 6. At the same time, the first spring 65 prevents the movable half-ring 62 and the fixed half-ring 61 from loosening when the conduit 2 is fixed, thus preventing the pipe from becoming loose. When the sliding block 64 moves away from the opening of the inner groove 63, the movable half-ring 62 moves into the inner groove 63, so that the movable ring plate 62 is partially housed inside the inner groove 63, thereby keeping the fixed half-ring 61 in an open state, which facilitates the conduit 2 to enter and exit the inner cavity of the annular bite 6.

[0044] Further, see Figure 3 For the aforementioned annular biting member 6, a groove 66 is provided at the top of the fixed half ring 61, the groove 66 is connected to the inner groove 63, a pushing block 67 is provided at the top of the fixed half ring 61, a connecting shaft is fixedly provided at the bottom of the pushing block 67, the connecting shaft is slidably disposed in the inner cavity of the groove 66 and one end is fixedly connected to the sliding block 64.

[0045] When the pushing block 67 moves along the sliding groove 66 toward the inner groove 63 away from the groove opening, the pushing block 67 drives the connecting shaft and the sliding block 64 at the bottom of the connecting shaft to move into the inner groove 63, thereby driving the movable ring plate 62 to move into the inner cavity of the inner groove 63, so that the fixed ring plate 61 is in an open state, which facilitates the conduit 2 to enter and exit the inner cavity of the annular bite 6. At this time, the first spring 65 is in a compressed state. When the conduit 2 enters the inner cavity of the fixed ring plate, the pushing block 67 is released, the first spring 65 loses its compressed state and returns to its elasticity, and drives the movable ring plate 62 to move out of the inner groove 63, thereby sealing the fixed ring plate 61 and fixing the conduit 2.

[0046] Further, see Figure 4 For the aforementioned baffle 7, a pushing component 9 is provided on one side of the baffle 7. The pushing component 9 includes a moving block 91. An arc-shaped groove 92 is provided on the side wall of the channel opening 5. A sliding plate 93 is fixedly provided on one side of the baffle 7. The sliding plate 93 is slidably disposed in the inner cavity of the arc-shaped groove 92. A guide groove 94 is provided at the bottom of the mask 1. A connecting block is fixedly provided at the bottom of the moving block 91. The connecting block is slidably disposed in the inner cavity of the guide groove 94 and one end is fixedly connected to the sliding plate 93.

[0047] The baffle 7 is retracted and extended through the sliding connection between the baffle 7 and the arc groove 92, thereby controlling the opening and closing of the channel opening 5, which facilitates the installation between the mask 1 and the conduit 2, as well as the fixation of the conduit 2.

[0048] Further, see Figure 4For the aforementioned baffle plate 7, a guide rod is fixedly provided in the inner cavity of the arc groove 92, the baffle plate 7 is sleeved on the outer periphery of the baffle plate 7, and a second spring 95 is provided on one side of the sliding plate 93, the second spring 95 is sleeved on the outer periphery of the guide rod;

[0049] After the conduit 2 is fixed, the elasticity provided by the second spring 95 ensures that the baffle 7 always closes the channel opening 5.

[0050] Further, see Figure 5 For the aforementioned baffle plate 7, the bottom of the mask 1 is provided with a slot 96, which is located on one side of the guide groove 94. The bottom of the moving block 91 is provided with a groove, and a locking block 97 is slidably provided in the inner cavity of the groove. The locking block 97 cooperates with the slot 96. A third spring 98 is provided on one side of the locking block 97, which is located in the inner cavity of the groove.

[0051] The cooperation between the slot 96 and the block 97 allows the baffle 7 to be fixed when it is stored, which facilitates the installation between the guide tube 2 and the mask 1. At the same time, the third spring 98 facilitates the overlap and separation between the slot 96 and the block 97.

[0052] Further, see Figure 6 For the mask 1 mentioned above, a rectangular through hole 10 is provided on one side of the front of the mask 1. A support block 11 is installed at the bottom of the inner cavity of the rectangular through hole 10. An air inlet valve 12 is installed on one side of the support block 11. An opening 13 is provided on the other side of the support block 11. A sealing plug 14 is installed in the inner cavity of the opening 13. An air outlet valve 15 is installed on the other side of the mask 1.

[0053] When simple oral cleaning of the patient is required, the user moves the shield 161 to the side of the built-in groove 162, so that the rectangular through hole 10 is fully exposed. Then, the sealing plug 14 is removed, and a corresponding cleaning cotton swab is passed through the through hole 13 to clean and wipe the patient's oral cavity. When the patient's oral cavity is too dry, the user introduces water vapor into the patient's oral cavity through the air inlet valve 12 to keep the patient's oral cavity moist and to allow some gas to be discharged from the air outlet valve 15. When the patient's oral cavity and the inside of the mask 1 are moist due to the temperature difference between the inside and outside of the oral cavity, the user introduces dry gas into the patient's oral cavity through the air inlet valve 12 to evaporate the water vapor in the patient's oral cavity and discharge it through the air outlet valve 15, thereby achieving a certain level of humidity in the patient's oral cavity.

[0054] Further, see Figure 7 and Figure 8For the aforementioned face mask 1, a sealing component 16 is provided at the rectangular through hole 10. The sealing component 16 includes a baffle plate 161. An internal groove 162 and a connecting groove 163 are respectively opened on the two side walls of the rectangular through hole 10. The connecting groove 163 is connected to the arc groove 92. The baffle plate 161 is slidably disposed in the inner cavity of the internal groove 162 and completely covers the rectangular through hole 10 when it moves. A retaining plate 164 is fixedly connected to the side of the baffle plate 161 near the connecting groove 163. The retaining plate 164 is slidably disposed in the inner cavity of the connecting groove 163. A pin 165 is fixedly connected to one side of the sliding plate 93. An insertion hole 166 is opened on one side of the retaining plate 164. The pin 165 is sleeved in the inner cavity of the insertion hole 166.

[0055] When the mask 1 is not in use, the baffle 7 is stored in the inner cavity of the arc-shaped groove 92. At this time, the pin 165 on one side of the sliding plate 93 coincides with the insertion hole 166 on the side of the clamping plate 164, thereby fixing the baffle 161. This ensures that the rectangular through hole 10 is sealed when the device is not in use, preventing the air inlet valve 12 from being contaminated. When the mask 1 is in use, the baffle 7 needs to fix the tube 2. At this time, the pin 165 is disengaged from the insertion hole 166, making the baffle 161 movable. The baffle 161 can be moved to expose the air inlet valve 12 and the through-hole 13, thereby enabling the cleaning of the patient's oral cavity and humidity control.

[0056] Further, see Figure 1 For the mask 1 mentioned above, elastic bands 17 are fixedly installed on both sides of the mask 1, and the two elastic bands 17 are connected by Velcro 18.

[0057] The mask 1 is fixed to the patient's face by fastening the two elastic bands 17 with Velcro 18.

[0058] Working principle: When using the laryngoscope, tilt the patient's head back and lift the chin forward and upward with both hands to open the mouth. Then, hold the laryngoscope handle with the left hand and insert the laryngoscope blade into the patient's mouth from the right corner of the mouth. Push the tongue to the left and slowly advance the blade until the uvula is visible. Lift the blade vertically and advance it until the epiglottis is exposed. After lifting the epiglottis, the glottis will be exposed. Then, insert the upper middle part of the tube 2 into the oral cavity from the right corner of the mouth until the tube 2 is close to the larynx. Move the tube end to the laryngoscope blade and carefully and accurately insert the tip of the tube 2 into the glottis. When inserting the tube with the help of the stylet, after the tip of the tube 2 enters the glottis, remove the stylet and then insert the tube 2 into the trachea.

[0059] After the cannulation operation is completed, the user pushes the moving block 91, and through the sliding connection between the baffle 7 and the arc groove 92, the baffle 7 is retracted into the inner cavity of the arc groove 92. At this time, the second spring 95 is in a compressed state, and the channel opening 5 is in an open state. When the baffle 7 is retracted into the inner cavity of the arc groove 92, the locking block 97 at the bottom of the moving block 91 first contacts one side wall of the guide groove 94, and the locking block 97 is retracted into the inner cavity of the groove, and the third spring 98 is in a compressed state. When the baffle 7 is completely retracted into the inner cavity of the arc groove 92, the locking block 97 is located at the locking slot 96. At this time, the third spring 98 is reset, and the locking block 97 is aligned with the locking slot 96, thereby fixing the moving block 91.

[0060] After the baffle 7 is stored, the user moves the push block 67. When the push block 67 moves along the sliding groove 66 toward the inner groove 63 away from the groove opening, the push block 67 drives the connecting shaft and the sliding block 64 at the bottom of the connecting shaft to move into the inner groove 63, thereby driving the movable ring plate 62 to move into the inner cavity of the inner groove 63, so that the fixed ring plate 61 is in the open state.

[0061] After both the channel opening 5 and the fixed half-ring 61 are open, the user places the mask 1 on the patient's face and then moves the mask 1 downwards, so that the catheter 2 moves from the channel opening 5 into the inner cavity of the fixed half-ring 61. When the catheter 2 moves into the inner cavity of the fixed half-ring 61 and contacts the inner wall of the fixed half-ring 61, the user releases the push block 67, the first spring 65 returns to its elastic state after being compressed, and drives the movable ring plate 62 to move outwards from the inner groove 63, thereby sealing the fixed ring plate 61 and fixing the catheter 2. Then the user moves the mask 1 to the side of the patient's face and makes the mask 1 completely fit the patient's face, while the patient bites the ring bite piece 6.

[0062] After the catheter 2 is fixed, the user moves the moving block 91 toward the channel opening 5. When the locking block 97 disengages from the locking slot 96, the second spring 95 returns to its elasticity, causing the baffle plate 7 to move toward the channel opening 5. As the baffle plate 7 moves toward the channel opening 5, the side of the baffle plate 7 near the annular bite 6 enters the incision 8. When the baffle plate 7 moves to completely close the channel opening 5, the side of the baffle plate 7 near the annular bite 6 is simultaneously located inside the incision 8. Since the baffle plate 7 is located inside the incision 8, it locks the annular bite 6, thus preventing the annular bite 6 from moving. At the same time, the part of the baffle plate 7 located inside the incision 8 contacts the catheter 2, pressing against and stabilizing it in the inner cavity of the annular bite 6, thereby stabilizing the section of the catheter 2 from the annular bite 6 to the lung.

[0063] After fixing the catheter 2, when a simple cleaning of the patient's mouth is required, the user moves the shield 161 to the side of the built-in groove 162, so that the rectangular through hole 10 is fully exposed. Then, the sealing plug 14 is removed, and a corresponding cleaning cotton swab is passed through the opening 13 to clean and wipe the patient's mouth. When the patient's mouth is too dry, the user introduces water vapor into the patient's mouth through the air inlet valve 12, so as to keep the patient's mouth moist and allow some gas to be discharged from the air outlet valve 15. When the patient's mouth and the inside of the mask 1 are moist due to the temperature difference between the inside and outside of the mouth, the user introduces dry gas into the patient's mouth through the air inlet valve 12, so that the water vapor in the patient's mouth evaporates and is discharged through the air outlet valve 15, thereby achieving a certain humidity in the patient's mouth.

[0064] When the mask 1 is not in use, the baffle 7 is stored in the inner cavity of the arc-shaped groove 92. At this time, the pin 165 on one side of the sliding plate 93 coincides with the insertion hole 166 on the side of the clamping plate 164, thereby fixing the baffle 161. This ensures that the rectangular through hole 10 is sealed when the device is not in use, preventing the air inlet valve 12 from being contaminated. When the mask 1 is in use, the baffle 7 needs to fix the tube 2. At this time, the pin 165 is disengaged from the insertion hole 166, making the baffle 161 movable. The baffle 161 can be moved to expose the air inlet valve 12 and the through-hole 13, thereby enabling the cleaning of the patient's oral cavity and humidity control.

[0065] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
