Description

Technical Field

[0001] This invention relates to a non-invasive ventilator mask for patients requiring nasogastric feeding, and belongs to the field of ventilator mask technology. Background Technology

[0002] A ventilator mask is an important medical device primarily used in medical or emergency situations to provide oxygen or regulate airflow to patients. Ventilator masks are typically made of soft materials and cover the mouth and nose. They connect the ventilator to the patient for artificial or assisted ventilation. Depending on the usage scenario and functional requirements, ventilator masks can be categorized into various types, such as oronasal masks, nasal masks, and full-face masks. These masks may differ in design and function to suit different patient needs. The ventilator mask plays a crucial role in the ventilator system, directly contacting the patient and ensuring the smooth delivery of oxygen or airflow into the patient's airway. Simultaneously, the mask's seal and comfort directly affect the patient's treatment experience and outcome. Choosing a suitable mask and correctly wearing and maintaining it are essential for improving the patient's treatment experience and outcome. During use, close monitoring of the patient's breathing and mask comfort is crucial, and regular cleaning, disinfection, and replacement are necessary to ensure its safety and effectiveness.

[0003] When choosing a ventilator mask, factors such as the patient's face shape, treatment pressure, and personal comfort need to be considered. Generally, the mask should have an adjustable size design to better fit different patients' face shapes and sizes. The material and seal of the mask are also important factors to consider. When wearing a ventilator mask, the correct steps must be followed. Generally, before wearing, the face should be cleaned and excess oil removed; when wearing, use your hand to hold the mask against the face and secure it firmly; after wearing, lie down to check the wearing effect and adjust to a comfortable sleeping position. Furthermore, during use, it is necessary to observe the patient's breathing and mask comfort; if any abnormalities are found, adjustments should be made promptly or medical personnel should be contacted.

[0004] The ventilator mask is an indispensable and important component of the ventilator system. However, non-invasive ventilator masks have shortcomings in clinical practice. Traditional ventilator masks are suitable for patients who do not require nasogastric feeding. For patients who need nasogastric feeding, the feeding tube needs to be inserted from the edge of the mask, which not only causes air leakage but also easily leads to pressure sores on the patient's face, increasing the patient's suffering. Furthermore, depending on the patient, there may be patients with long-term indwelling nasogastric tubes that require regular tube changes, which can easily cause air leakage problems during use, making the use of ventilator masks inconvenient.

[0005] Chinese patent document CN117159872A describes a non-invasive ventilator mask, which includes a mask body, an oxygen tubing, and a fixing strap. The mask body has several first through holes for mounting a plug-in structure, and the plug-in structure has second through holes for inserting a tubing, such as a nasogastric feeding tube. This structure has too many through holes, which significantly increases the difficulty of mask body design and is prone to air leakage, resulting in less than ideal performance in practical applications.

[0006] Chinese patent document CN206642191U describes a non-invasive ventilator mask with a nasogastric tube channel. The nasogastric tube port is provided on the mask shell. The nasogastric tube interface consists of three parts: a channel base connected to the mask shell, an airtight nut, and a channel sealing cap. This effectively solves the problem of mask leakage. However, due to the addition of heavy components such as the channel base and nut, although the leakage problem is solved, it puts a lot of pressure on the wearer's face. Wearing it for a long time can easily cause pressure sores.

[0007] We designed a non-invasive ventilator mask (CN211675785U) at our affiliated Tongren Hospital. It consists of an outer mask and an inner mask. The outer mask has a nasogastric tube insertion port, while the inner mask has four insertion points on its side for nasogastric tubes, gastric tubes, nebulizer tubes, etc. This separate design allows for different patient needs to be met by simply replacing the inner mask. While this nominally reduces costs for users, it significantly increases costs for manufacturers. This is because the inner mask is typically made of silicone or latex, and it needs to be separated to create four insertion points for the nasogastric tube. Silicone or latex cannot be molded, making it difficult to seal the nasogastric tube. Therefore, the overall cost of the finished mask will be very high.

[0008] However, there is an urgent need in the existing technology for a low-cost, non-invasive ventilator mask that addresses the issues of air leakage and pressure sores and can be used by patients requiring nasogastric feeding. Summary of the Invention

[0009] In view of the above-mentioned technical problems existing in the prior art, the present invention aims to provide a non-invasive ventilator mask that can solve the problems of air leakage and pressure sores when used for patients receiving nasogastric feeding.

[0018] In this technical solution, the connecting mechanism includes a connecting tube and a locking rod. The connecting tube is fixedly connected to the outer wall of the breathing mask. The connecting tube is correspondingly arranged on one side of the through hole. The inner diameter of the connecting tube is larger than the diameter of the through hole. A nasogastric tube is movably sleeved inside the connecting tube. The end of the connecting tube away from the breathing mask is fixedly connected to several locking rods. There are four locking rods. The four locking rods are evenly distributed to the edge of the connecting tube, and each locking rod has an L-shaped cross-section.

[0019] In this technical solution, the sealing assembly includes a sleeve, which is movably connected to the nasogastric tube. Several evenly distributed guide grooves are provided on the edge of the sleeve, and each guide groove corresponds to a hook at one end of the lever. Two symmetrically distributed prying blocks are fixedly connected to one end of the sleeve.

[0020] In this technical solution, a pressure block is fixedly connected to the other end of the sleeve. The pressure block has an annular structure and is fitted into the inner wall of the connecting tube. The inner diameter of the pressure block is larger than the outer diameter of the nasogastric tube. The pressure block is made of deformable rubber material, and the thickness of the sleeve is equal to the length of the vertical rod at the other end of the clamping rod.

[0021] In this technical solution, the packaging assembly is composed of a latex tube, one end of which is fitted and connected to the edge of the connecting tube, and the other end of the latex tube is provided with a constriction.

[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will understand that this description is exemplary and the present invention is not limited to the scope of the described embodiments.

[0043] Figure 1 This is a schematic diagram of the overall three-dimensional structure of a non-invasive ventilator mask for nasogastric feeding patients according to a specific embodiment of the present invention. Figure 2 This is a three-dimensional structural diagram of the connection assembly of the non-invasive ventilator mask for patients requiring nasogastric feeding. Figure 8 , 9 These are top-view and rear-view structural diagrams, Figure 10 , 11 They are shown respectively Figure 2 Point A in the middle and Figure 3 A magnified schematic diagram of the structure at point B in the middle.

[0044] like Figure 1 , 2 As shown in Figures 8-11, the non-invasive ventilator mask for patients requiring nasogastric feeding includes:

[0045] A connecting component 200 is installed on the mask assembly 100. The connecting component 200 consists of a connecting mechanism and a sealing mechanism, with the sealing mechanism and the connecting mechanism located on the inner and outer sides of the mask assembly 100, respectively. A nasogastric tube 208 is inserted through the connecting mechanism. A sealing component 300 is movably sleeved on the surface of the nasogastric tube 208 and is fitted into the inside of the connecting mechanism. A wrapping component 400 has one end attached to the surface of the connecting mechanism, the sealing component 300 is located inside the wrapping component 400, and the other end of the wrapping component 400 is attached to the surface of the nasogastric tube 208.

[0046] In a preferred embodiment of the present invention, a connecting component 200 is provided on the mask assembly 100 for quick installation of the nasogastric tube 208, and the connection of the nasogastric tube 208 is sealed by the sealing component 300 and the wrapping component 400 to ensure that the mask assembly 100 will not leak during use. At the same time, the detachable sealing component 300 and the wrapping component 400 facilitate the subsequent wearing of the breathing mask 101 by the patient wearing the nasogastric tube 208, which improves the convenience of use without affecting the nasogastric tube 208, improves the stability during the wearing and removal process, and can effectively fix the nasogastric tube 208, improving the anti-pull function of the nasogastric tube 208.

[0047] like Figure 3-6 As shown, the mask assembly 100 consists of a breathing mask 101. The inner and outer sides of the breathing mask 101 are fixedly connected to a sealing mechanism and a connecting mechanism, respectively. The sealing mechanism is correspondingly arranged above the connecting mechanism. The breathing mask 101 located below the sealing mechanism has a through hole 206 for the nasogastric tube 208 to pass through. Figure 6 (as shown), and the breathing mask 101 at the edge of the through hole 206 is provided with an arc-shaped bevel 207 (as shown). Figure 6 As shown in the diagram, the breathing mask 101 is fixedly connected to the breathing tube 107 in the middle, the through hole 206 is located on one side of the breathing tube 107, and the through hole 206 corresponds to the nose position of the breathing mask 101.

[0048] In another preferred embodiment of the present invention, the sealing mechanism at the through hole 206 can be used after the nasogastric tube 208 is removed from the nasogastric patient or for use by patients with breathing difficulties. When used by nasogastric patients, the nasogastric tube 208 is inserted through the through hole 206, which solves the problem of air leakage caused by the nasogastric tube 208 extending from the edge of the breathing mask 101 when the nasogastric patient wears the breathing mask 101, and the problem of pressure sores caused by the breathing mask 101 pressing the nasogastric tube 208 tightly against the patient's face for a long time. This improves the ease of installation of the nasogastric tube 208. Furthermore, the bevel 207 provided at the edge of the through hole 206 facilitates the sealing mechanism to seal the through hole 206, avoids air leakage when the breathing mask 101 is used alone, and improves the performance of the breathing mask 101.

[0049] The breathing mask 101 is connected to adjusters 102 on both sides of its bottom. The breathing mask 101 is connected to the lower strap 103 through the adjusters 102. A connecting strap 104 is fixedly connected to the middle of the lower strap 103, and the top of the connecting strap 104 is fixedly connected to the middle of the upper strap 105. Both ends of the upper strap 105 are connected to the adjusting strap 106.

[0050] In this invention, after the nasogastric tube 208 is placed, the through hole 206 of the breathing mask 101 is passed through the externally located nasogastric tube 208, and then the breathing mask 101 is put on. After the breathing mask 101 is put on the patient's face, the lower strap 103 is put on the back of the patient's head and adjusted in place by the adjuster 102 so that the connecting strap 104 fits against the back of the patient's head. Then the upper strap 105 is put on the top of the patient's head and the tightness is adjusted by the adjusting strap 106 to achieve stable wearing of the breathing mask 101. At this time, the nasogastric tube 208 is located inside the through hole 206 and does not interfere with each other, which facilitates the quick wearing of the breathing mask 101 and avoids affecting the nasogastric tube 208 during the wearing process.

[0051] like Figure 5 , 6 As shown, the sealing mechanism includes a blocking block 204 and a sealing plug 205. One side of the blocking block 204 is fixedly connected to the sealing plug 205. The blocking block 204 is connected to one end of the connecting rope 203. The other end of the connecting rope 203 is fixedly connected to the inner wall of the breathing mask 101. The sealing plug 205 is fitted and inserted into the through hole 206. The sealing plug 205 is fitted and connected to the inclined surface 207. The blocking block 204 is fitted and connected to the inner wall of the breathing mask 101.

[0052] In this technical solution, the connecting rope 203 connects the plug 204 and the sealing plug 205, allowing the plug 204 to move inside the breathing mask 101. When the patient is only wearing the breathing mask 101, the sealing plug 205 on the plug 204 blocks the through hole 206, so that the plug 204 fits against the inner wall of the breathing mask 101, thus sealing the through hole 206 and preventing air from entering the connecting tube 201 and causing bacterial growth.

[0053] The connecting mechanism includes a connecting tube 201 and a locking rod 202. The connecting tube 201 is fixedly connected to the outer wall of the breathing mask 101. The connecting tube 201 is correspondingly arranged on one side of the through hole 206. The inner diameter of the connecting tube 201 is larger than the diameter of the through hole 206. A nasogastric tube 208 is movably sleeved inside the connecting tube 201. The end of the connecting tube 201 away from the breathing mask 101 is fixedly connected to several locking rods 202. There are four locking rods 202. The four locking rods 202 are evenly distributed to the edge of the connecting tube 201, and each locking rod 202 has an L-shaped cross-section.

[0054] In this technical solution, the connecting mechanism facilitates the wearing of the breathing mask 101. After the nasogastric tube 208 is worn and fixed, when the breathing mask 101 is passed through the nasogastric tube 208, the nasogastric tube 208 moves inside the connecting tube 201. At the same time, a cavity for the clamping block 302 is formed between the nasogastric tube 208 and the connecting tube 201. A locking rod 202 is provided on the edge of the connecting tube 201. This allows the installation of the nasogastric tube 208 to be unaffected, while the locking rod 202 cooperates with the sealing component 300 to lock the sealing component 300, ensuring the stability of the seal.

[0055] The sealing assembly 300 includes a sleeve 301, which is movably sleeved with the nasogastric tube 208. The sleeve 301 has several evenly distributed guide grooves 303 on its edge, each guide groove 303 corresponding to a hook at one end of the locking rod 202. Two symmetrically distributed pry blocks 304 are fixedly connected to one end of the sleeve 301. A pressure block 302 is fixedly connected to the other end of the sleeve 301. The pressure block 302 has an annular structure and is fitted into the inner wall of the connecting tube 201. The inner diameter of the pressure block 302 is larger than the outer diameter of the nasogastric tube 208. The pressure block 302 is made of deformable rubber material, and the thickness of the sleeve 301 is equal to the length of the vertical rod at the other end of the locking rod 202.

[0056] In this technical solution, after both the nasogastric tube 208 and the breathing mask 101 are worn, there is a gap at the through hole 206. When the patient breathes, gas will leak from the gap. After wearing, the sleeve 301 is moved from one end of the nasogastric tube 208 to the surface of the breathing mask 101. At this time, the sleeve 301 moves the pressure block 302 into the inside of the connecting tube 201, so that the pressure block 302 squeezes the inner wall of the connecting tube 201. The elastic deformation of the pressure block 302 makes it fit tightly against the inner wall of the connecting tube 201. At this time, the nasogastric tube 208 is located inside the pressure block 302, and the pressure block 302 does not contact the nasogastric tube 208, which facilitates the quick installation of the sleeve 301. When the pressure block 302 is squeezed by the inner wall of the connecting tube 201, the pressure block 302 undergoes elastic deformation, so that the pressure block 302 fits against the surface of the nasogastric tube 208, thereby achieving a sealing performance between the nasogastric tube 208 and the connecting tube 201.

[0057] The sleeve 301 is accurately installed by the cooperation of the guide groove 303 and the locking rod 202. The rotation of the sleeve 301 causes the hook on the locking rod 202 to be misaligned with the guide groove 303, which facilitates quick locking after the sleeve 301 is installed in place. The lever 304 can be used to easily drive the sleeve 301 to rotate, improving the convenience of operation.

[0058] The following reference Figure 7 The package component 400 is described in detail.

[0059] like Figure 7 As shown, the packaging assembly 400 is composed of a latex tube 401. One end of the latex tube 401 is fitted and connected to the edge of the connecting tube 201. The other end of the latex tube 401 is provided with a constriction 402. A sleeve 301 is sleeved inside the latex tube 401. The latex tube 401 is made of elastic material, and the constriction 402 is movably fitted to the surface of the nasogastric tube 208. A connecting block 403 is fixedly connected to the surface of the latex tube 401. The connecting block 403 is located on the surface of the constriction 402 at one end of the latex tube 401. Both ends of the connecting block 403 are fixedly connected to tension ropes 404. Both tension ropes 404 are located on the surface of the constriction 402, and the two tension ropes 404 are staggered and connected to each other.

[0060] In this technical solution, after the sealing component 300 is installed, one end of the latex tube 401 is sleeved on the surface of the connecting tube 201. The elasticity of the latex tube 401 is used to achieve a tight fit with the connecting tube 201. At this time, the latex tube 401 wraps around the surface of the connecting component 200, and at the same time, it drives the constriction 402 to move to the surface of the nasogastric tube 208 on one side of the connecting component 200. After the operation is completed, the two tension ropes 404 on the connecting block 403 are tied together, so that the squeezing force generated by the tension ropes 404 will make the constriction 402 of the latex tube 401 fit against the surface of the nasogastric tube 208, which can ensure further sealing between the nasogastric tube 208 and the outside and improve the air leakage prevention function.

[0061] Two knobs 209 are threaded onto the surface of the connecting tube 201. The two knobs 209 are symmetrically distributed on both sides of the connecting tube 201. Both knobs 209 are located on one side of the latex tube 401, and each knob 209 extends into the interior of the connecting tube 201. A pressure ring 210 is rotatably connected to the end of the knob 209 located inside the connecting tube 201. There are two pressure rings 210, which are symmetrically distributed on both sides of the nasogastric tube 208. The inner diameter of the pressure ring 210 is smaller than the outer diameter of the nasogastric tube 208. The pressure ring 210 has an arc-shaped cross-section and is in close contact with the surface of the nasogastric tube 208.

[0062] In this technical solution, after the nasogastric tube 208 and the breathing mask 101 are both worn, the sealing assembly 300 is installed and the pressure block 302 is used to press and fix the nasogastric tube 208. The tension rope 404 on the latex tube 401 is used to press and fix the nasogastric tube 208, which can achieve the initial fixation of the nasogastric tube 208. Then, the knob 209 on the connecting tube 201 is tightened, so that the knob 209 drives the pressure ring 210. When the pressure rings 210 are spliced ​​together, the pressure rings 210 squeeze and fix the surface of the nasogastric tube 208, thereby achieving the limitation of the nasogastric tube 208. This can play the role of preventing the nasogastric tube 208 from being pulled and avoid the problem of the nasogastric tube 208 shifting when it is used.

[0063] During disassembly, first untie the tension rope 404, then remove the latex tube 401 from the surface of the connecting tube 201. Next, rotate the lever 304 so that the lever 304 drives the sleeve 301 to rotate between the four locking rods 202. When the sleeve 301 drives the guide groove 303 to rotate and align with the locking rods 202, pull out the pressure block 302 on the sleeve 301 together, so that the sleeve 301 is separated from the inside of the connecting tube 201. The sleeve 301 and the pressure ring 210 do not contact the surface of the nasogastric tube 208, making it easy to retract the sleeve 301 from the nasogastric tube 208. After the operation is completed, remove the breathing mask 101 and finally remove the nasogastric tube 208. This facilitates the use of nasogastric feeding patients and makes it easier for nasogastric feeding patients to wear the breathing mask 101, improving the ease of use.

[0064] In summary, the present invention has been described in detail with reference to specific embodiments. By simultaneously utilizing a sealing component and a wrapping component to achieve a seal at the connection between the nasogastric tube and the breathing mask, air leakage during mask use can be avoided. This solves the problems of air leakage and pressure sores on the patient's face caused by inserting the nasogastric tube from the edge of the mask, thus improving the performance of the ventilator mask. Furthermore, the detachable sealing and wrapping components facilitate quick removal after use, simultaneously addressing potential pulling issues with the nasogastric tube and providing a function to secure the tube during use. This ensures that the patient wearing the breathing mask is not affected while maintaining stable fixation of the nasogastric tube, improving its anti-pulling function and enhancing the overall effectiveness of the ventilator mask. Because the present invention has a simple design and is lightweight, it significantly reduces the possibility of pressure sores, effectively ensuring no air leakage even during prolonged use and preventing interference between the nasogastric tube and the mask body. The structural design is reasonable and suitable for widespread application.

[0065] The present invention has been described in detail above. Those skilled in the art will understand that the present invention is not limited to the above-described embodiments, and various changes and modifications can be made. As long as they do not depart from the spirit and essence of the present invention, all such changes and modifications should fall within the protection scope of the present invention, which is defined by the appended claims.
