Description

Technical Field

[0001] The invention relates to a non-invasive ventilator mask for patients with nasogastric feeding, and belongs to the technical field of ventilator masks. Background Art

[0002] The ventilator mask is an important medical device, mainly used in medical or emergency situations to provide oxygen or regulate respiratory airflow to patients. The ventilator mask is usually made of soft materials that can cover the mouth and nose, and is used to connect the ventilator device and the patient to implement artificial ventilation or assisted ventilation. According to different usage scenarios and functional requirements, the ventilator mask can be divided into many types, such as oral and nasal masks, nasal masks, full-face masks, etc. These masks may differ in design and function to meet the needs of different patients. The ventilator mask plays a key role in the ventilator system. It is in direct contact with the patient to ensure that oxygen or airflow can be smoothly delivered to the patient's respiratory tract. At the same time, the sealing and comfort of the mask also directly affect the patient's treatment experience and effect. Choosing a suitable mask and wearing and maintaining it correctly are of great significance to improving the patient's treatment experience and effect. During use, the patient's breathing condition and the comfort of the mask should be closely monitored, and it should be cleaned, disinfected and replaced regularly to ensure its safety and effectiveness.

[0003] When choosing a ventilator mask, you need to consider factors such as the patient's face shape, treatment pressure, and personal comfort. Generally speaking, the mask should be designed with an adjustable size to better fit the face shape and size of different patients. At the same time, the material and sealing of the mask are also important factors to consider when choosing. When wearing a ventilator mask, you need to follow the correct steps. Generally speaking, you should wash your face and remove excess oil before wearing it; when wearing it, hold the mask with your hands to fit the face and fix it; after wearing it, you need to lie down to check the wearing effect and adjust a comfortable sleeping position. In addition, you need to pay attention to the patient's breathing and the comfort of the mask during use. If you find any abnormalities, you should adjust it in time or contact medical staff.

[0004] The ventilator mask is an indispensable and important part of the ventilator system. In clinical practice, non-invasive ventilator masks have defects. Traditional ventilator masks are suitable for patients who do not need nasogastric feeding. For patients who need nasogastric feeding, the nasogastric feeding tube needs to be inserted from the edge of the mask, which not only causes air leakage in the mask, but also easily causes pressure sores on the patient's face, increasing the patient's pain. In addition, for different patients, there may be patients who have long-term nasogastric feeding tubes and regularly replace nasogastric feeding tubes. During use, air leakage problems are prone to occur, which brings inconvenience to the use of ventilator masks.

[0005] Chinese patent document CN117159872A describes a non-invasive ventilator mask, which includes a mask body, an oxygen conduit and a fixing belt. The mask body is provided with a plurality of first through holes, which are used to install a plug-in structure, and the plug-in structure is provided with a second through hole, which is used to insert a catheter such as a nasogastric feeding catheter. This structure is provided with too many through holes, which increases the difficulty of designing the mask body and is prone to air leakage. In practice, the application effect is not very ideal.

[0006] Chinese patent document CN206642191U describes a non-invasive ventilator mask with a nasogastric tube channel, which is provided with a nasogastric tube port on the mask shell. The nasogastric tube interface consists of a channel base connected to the mask shell, an airtight nut, and a channel closing cap. The problem of mask leakage is effectively solved. However, due to the additional heavy parts such as the channel base and the nut, although the leakage problem is solved, the wearer's face is under great pressure, and pressure sores are easily formed if worn for a long time.

[0007] A non-invasive ventilator mask (CN211675785U) was designed in Tongren Hospital affiliated to our school. It includes an outer mask and an inner mask. The outer mask is provided with a nasogastric tube operation port, and the inner mask side part forms 4 sites for indwelling nasogastric tubes, gastric tubes, atomization tubes and other components. Through this split design, only the inner mask needs to be replaced according to different patients to meet the needs of different patients. Although the cost of users is nominally reduced, the cost of producers is greatly increased because the inner mask is usually made of silicone or latex material, which needs to be separated to form 4 points for indwelling nasogastric tubes, and silicone or latex cannot be shaped, and it is difficult to indwell and seal nasogastric tubes. In this way, the cost of the overall finished mask will be very expensive.

[0008] However, there is an urgent need in the prior art for a low-cost non-invasive ventilator mask that can be used by nasogastric feeding patients while addressing the issues of air leakage and pressure sores. Summary of the invention

DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with specific embodiments with reference to the accompanying drawings. Those skilled in the art will appreciate that the description is exemplary and the present invention is not limited to the scope of the described embodiments.

[0034] Figure 1 The present invention is a schematic diagram showing 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 schematic diagram of the three-dimensional structure of the connection components of the non-invasive ventilator mask for nasogastric feeding patients. Figure 8 , 9 They are top view and rear view structural diagrams, Fig.10 , 11 Shown respectively Figure 2 Schematic diagram of the partial enlarged structure at points A and B in the middle.

[0035] like Figure 1 , 2 , 8-11, the non-invasive ventilator mask for the nasogastric feeding patient comprises: A connecting assembly 200 installed on the mask assembly 100, wherein the connecting assembly 200 is composed of a connecting mechanism and a sealing mechanism, and the sealing mechanism and the connecting mechanism are respectively located on the inner and outer sides of the mask assembly 100, and a nasogastric tube 208 is inserted through the interior of the connecting mechanism; a sealing assembly 300, wherein the sealing assembly 300 is movably connected to the surface of the nasogastric tube 208, and the sealing assembly 300 is connected to the interior of the connecting mechanism in an interlocking manner; a wrapping assembly 400, wherein one end of the wrapping assembly 400 is fittedly connected to the surface of the connecting mechanism, the sealing assembly 300 is located inside the wrapping assembly 400, and the other end of the wrapping assembly 400 is fittedly connected to the surface of the nasogastric tube 208.

[0036] 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 have leakage problems during use. At the same time, the detachable sealing component 300 and the wrapping component 400 can facilitate the subsequent wearing of the breathing mask 101 by the patient wearing the nasogastric tube 208, while improving the convenience of use without affecting the nasogastric tube 208, improving the stability during wearing and removal, and at the same time, the nasogastric tube 208 can be effectively fixed to improve the anti-pulling function of the nasogastric tube 208.

[0037] like Figure 3-6 As shown, the mask assembly 100 is composed of a breathing mask 101, and the inner and outer sides of the breathing mask 101 are fixedly connected to a blocking mechanism and a connecting mechanism respectively. The blocking mechanism is correspondingly arranged above the connecting mechanism, and the breathing mask 101 located below the blocking mechanism is provided with a through hole 206 ( Figure 6 ), and the breathing mask 101 at the edge of the through hole 206 is provided with a curved inclined surface 207 ( Figure 6 As shown), the middle part of the breathing mask 101 is fixedly connected to the breathing tube 107, 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.

[0038] In another preferred embodiment of the present invention, the through hole 206 is blocked by a blocking mechanism. After the nasogastric patient removes the nasogastric tube 208 or for patients with normal breathing difficulties, the nasogastric tube 208 can be inserted through the through hole 206 when the patient is using it. This can solve the problem of leakage caused by the nasogastric tube 208 extending from the edge of the breathing mask 101 when the existing nasogastric patient wears the breathing mask 101, and the breathing mask 101 presses the nasogastric tube 208 against the patient's face for a long time and causes pressure sores. The installation convenience of the nasogastric tube 208 is improved, and a slope 207 is provided on the edge of the through hole 206, which can facilitate the blocking of the through hole 206 by the blocking mechanism, avoid the problem of leakage when the breathing mask 101 is used alone, and improve the performance of the breathing mask 101.

[0039] Regulators 102 are connected to both sides of the bottom of the breathing mask 101, and the breathing mask 101 is connected to the lower strap 103 through the regulator 102. A connecting belt 104 is fixedly connected to the middle of the lower strap 103, and the top of the connecting belt 104 is fixedly connected to the middle of the upper strap 105, and both ends of the upper strap 105 are connected to the adjusting belt 106.

[0040] In the present invention, after the nasogastric tube 208 is placed, the through hole 206 of the breathing mask 101 is passed through the nasogastric tube 208 located outside, and then the breathing mask 101 is worn. After the breathing mask 101 is worn on the patient's face, the lower strap 103 is worn on the back of the patient's head, and after adjusting it into place through the adjuster 102, the connecting strap 104 is fitted behind the patient's head, and then the upper strap 105 is worn on the top of the patient's head. After adjusting the tightness through the adjustment strap 106, the stable wearing of the breathing mask 101 is achieved. 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.

[0041] like Figure 5 ,6 As shown, the blocking 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 engaged and plugged into the inside of the through hole 206, the sealing plug 205 is fit-fitted and connected to the inclined surface 207, and the blocking block 204 is fit-fitted and connected to the inner wall of the breathing mask 101.

[0042] In the present technical solution, the connection between the blocking block 204 and the sealing plug 205 is achieved through the connecting rope 203, so that the blocking block 204 can be moved inside the breathing mask 101, so that when the patient only wears the breathing mask 101, the sealing plug 205 on the blocking block 204 blocks the through hole 206, so that the blocking block 204 fits the inner wall of the breathing mask 101, thereby sealing the through hole 206 and preventing air from entering the connecting tube 201 to cause bacteria growth problems.

[0043] The connecting mechanism includes a connecting tube 201 and a clamping 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 connecting tube 201 at one end away from the breathing mask 101 is fixedly connected to a plurality of clamping rods 202. There are four clamping rods 202. The four clamping rods 202 are evenly distributed to the edge of the connecting tube 201, and the cross-section of each clamping rod 202 is an L-shaped structure.

[0044] In the present technical solution, the connection mechanism can facilitate 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 pressing block 302 to be embedded is formed between the nasogastric tube 208 and the connecting tube 201, and a clamping rod 202 is provided on the edge of the connecting tube 201. While not affecting the installation of the nasogastric tube 208, the sealing assembly 300 can be locked by cooperating with the clamping rod 202 and the sealing assembly 300, thereby ensuring stability during sealing.

[0045] The sealing assembly 300 includes a sleeve 301, the interior of the sleeve 301 is movably connected to the nasogastric tube 208, and a plurality of evenly distributed guide grooves 303 are opened on the edge of the sleeve 301, each of the guide grooves 303 is distributed corresponding to the hook at one end of the clamping rod 202, and one end of the sleeve 301 is fixedly connected to two symmetrically distributed shifting blocks 304; the other end of the sleeve 301 is fixedly connected to a pressing block 302, the pressing block 302 is an annular structure and is engaged and connected with the inner wall of the connecting tube 201, the inner diameter of the pressing block 302 is larger than the outer diameter of the nasogastric tube 208, the pressing 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 clamping rod 202.

[0046] In the present technical solution, after the nasogastric tube 208 and the breathing mask 101 are both worn, there is a gap at the through hole 206, and the patient will cause gas to leak from the gap when breathing. 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 drives the pressing block 302 to move to the inside of the connecting tube 201, so that the pressing block 302 squeezes the inner wall of the connecting tube 201, and utilizes the elastic deformation of the pressing block 302 to make it fit tightly with the inner wall of the connecting tube 201. At this time, the nasogastric tube 208 is located inside the pressing block 302, and the pressing block 302 does not contact the nasogastric tube 208, which facilitates the rapid installation of the sleeve 301. When the pressing block 302 is squeezed by the inner wall of the connecting tube 201, the pressing block 302 is elastically deformed, so that the pressing block 302 fits on the surface of the nasogastric tube 208, thereby achieving sealing performance between the nasogastric tube 208 and the connecting tube 201.

[0047] The accurate installation of the sleeve 301 is achieved by setting the cooperation between the guide groove 303 and the clamping rod 202, and the hook on the clamping rod 202 and the guide groove 303 are staggered by the rotation of the sleeve 301, so that the sleeve 301 can be quickly locked after it is installed in place. The sleeve 301 can be easily driven to rotate by using the shift block 304, thereby improving the convenience of operation.

[0048] Refer to the following Figure 7 The wrapping assembly 400 is described in detail.

[0049] like Figure 7As shown, the wrapping component 400 is composed of a latex tube 401, and the latex tube 401 is fitted and connected to the edge of one end of the connecting tube 201, and the other end of the latex tube 401 is provided with a constriction 402, and the latex tube 401 is sleeved with a sleeve 301 inside, and the latex tube 401 is made of elastic material, and the constriction 402 is movably sleeved with the surface of the nasogastric tube 208; a connecting block 403 is fixedly connected to the surface of the latex tube 401, and the connecting block 403 is located on the surface of the constriction 402 at one end of the latex tube 401, and both ends of the connecting block 403 are fixedly connected to the tensioning rope 404, and the two tensioning ropes 404 are both located on the surface of the constriction 402, and the two tensioning ropes 404 are staggered and connected to each other.

[0050] In the present 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, and the elasticity of the latex tube 401 is used to achieve a tight sleeve connection with the connecting tube 201. At this time, the latex tube 401 is wrapped around the surface of the connecting component 200, and at the same time 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 tensioning ropes 404 on the connecting block 403 are tied together, so that the extrusion force generated by the tensioning ropes 404 makes the constriction 402 of the latex tube 401 fit on the surface of the nasogastric tube 208, which can ensure further sealing of the nasogastric tube 208 with the outside and improve the anti-leakage function.

[0051] The surface of the connecting tube 201 is threadedly connected with two knobs 209, which are symmetrically distributed on both sides of the connecting tube 201, and both knobs 209 are located on one side of the latex tube 401, and each knob 209 extends into the inside of the connecting tube 201, and the end of the knob 209 located inside the connecting tube 201 is rotatably connected with a pressure ring 210, and there are two pressure rings 210, which are symmetrically distributed on both sides of the nasogastric tube 208, and the inner diameter of the pressure ring 210 is smaller than the outer diameter of the nasogastric tube 208, and the cross-section of the pressure ring 210 is an arc structure, and the pressure ring 210 is fitted and connected to the surface of the nasogastric tube 208.

[0052] In the present technical solution, after the nasogastric tube 208 and the breathing mask 101 are both worn, the sealing assembly 300 is installed and the nasogastric tube 208 is compressed and fixed by the pressure block 302, and the nasogastric tube 208 is compressed and fixed by the tensioning rope 404 on the latex tube 401, so that the nasogastric tube 208 can be initially fixed, and then the knob 209 on the connecting tube 201 is tightened to make the knob 209 drive the pressure ring 210, so that when the pressure rings 210 are spliced ​​with each other, the pressure ring 210 squeezes and fixes the surface of the nasogastric tube 208, thereby achieving the limitation of the nasogastric tube 208, which can play the anti-pulling function of the nasogastric tube 208, and avoid the deviation problem of the nasogastric tube 208 when the nasogastric tube 208 is used.

[0053] When disassembling, first untie the tension rope 404, remove the latex tube 401 from the surface of the connecting tube 201, and then rotate the shift block 304 to make the shift block 304 drive the sleeve 301 to rotate between the four clamping rods 202. When the sleeve 301 drives the guide groove 303 to rotate and corresponds to the clamping rod 202, the pressing block 302 on the sleeve 301 is pulled out together to separate the sleeve 301 from the inside of the connecting tube 201, and the sleeve 301 and the pressure ring 210 are not in contact with the surface of the nasogastric tube 208, so that the sleeve 301 is conveniently returned from the nasogastric tube 208. When the operation is completed, the breathing mask 101 is removed, and finally the nasogastric tube 208 is removed, which is convenient for patients with nasogastric feeding to use it, and also convenient for patients with nasogastric feeding to wear the breathing mask 101 conveniently, thereby improving the convenience of use.

[0054] In summary, the present invention has been described in detail with reference to the specific implementation methods. Since the sealing of the connection between the nasogastric tube and the respiratory mask is achieved by the cooperation of the sealing component and the wrapping component at the same time, the problem of air leakage during the use of the respiratory mask can be avoided, and the problem of air leakage caused by the nasogastric tube extending from the edge of the mask and the patient's face suffering from pressure sores can be solved, and the use performance of the ventilator mask can be improved. On the other hand, by providing a detachable sealing component and a wrapping component, it can be conveniently removed quickly after use, and the problem of pulling that may be caused to the nasogastric tube can be solved at the same time. The function of fixing the nasogastric tube during use is provided, ensuring that the nasogastric feeding patient wearing the respiratory mask is not affected, and the nasogastric feeding tube can be stably fixed, improving the anti-pulling function of the nasogastric feeding tube, and improving the use effect of the ventilator mask. Because the present invention has a simple design structure and a light weight, it further greatly reduces the possibility of generating pressure sores, effectively ensures that there is no leakage in the case of long-term use and does not cause the nasogastric tube to interfere with the mask body, and the structural design is reasonable and suitable for promotion.
