Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a pressure injury-preventing ventilator mask. Background Art

[0002] As an important auxiliary device in respiratory support therapy, ventilator masks are widely used in hospitals, emergency centers, home care and other fields. Its main function is to provide patients with necessary oxygen supply or assisted breathing to maintain their normal respiratory function. With the continuous advancement of medical technology, the design of ventilator masks is also being continuously optimized to improve patient comfort and reduce discomfort and complications during treatment.

[0003] According to publication number CN110812650B, a pressure injury prevention ventilator mask in the field of medical devices is disclosed. This ventilator mask includes a mask part covering the patient's face and a negative pressure machine for supplying oxygen. An air duct is connected between the breathing part and the negative pressure machine. The mask part includes a chin, a nasal pressure part and an oral part. The side wings of the nasal pressure part have a Möbius ring structure. The surface of the Möbius ring is provided with an arc groove, and the two ends of the Möbius ring are bonded to the mask part, and the middle part of the Möbius ring is loose.

[0004] However, there are still problems. According to the above-mentioned comparative documents, the respiratory mask is attached to the patient's nose as a whole and keeps the patient's nose in a sealed state. Even if a Möbius ring is set, it only has a certain buffering effect on the extrusion force. When the patient turns his head, the respiratory mask is still easily squeezed and rubbed, causing friction on the skin in contact with the surface of the respiratory mask, which will still cause discomfort to the patient's skin surface, and over time will cause the rubbed skin to become red, swollen or broken.

[0005] Therefore, there is an urgent need for an anti-pressure injury ventilator mask to solve the existing technical problems. Summary of the invention

[0006] The object of the present invention is to provide a pressure-injury-proof ventilator mask to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the purpose of the present invention is to provide an anti-pressure injury ventilator mask, including a mask mechanism, a sliding mechanism and an adjustment mechanism. The sliding mechanism is movably installed on the right side of the mask mechanism surface, and the adjustment mechanism is movably installed on the lower surface of the sliding mechanism. A cover is provided on the right side of the mask mechanism surface, and an adjustment plate is installed on the surface of the sliding mechanism. Bearings are connected on both sides of the cover cover surface. The cover cover is rotated and adjusted at the center position of the lower surface of the adjustment plate through the bearings, and the cover cover and the adjustment plate are synchronously slid up and down and adjusted on the right side of the mask mechanism surface through the sliding mechanism.

[0008] As a further improvement of the present technical solution, the mask mechanism includes a nose bridge sticker, elastic bands are connected to the two ends of the left side of the nose bridge sticker surface, a buckle is connected to one side of the elastic band surface, a cover is installed at the center position of the right side of the nose bridge sticker surface, bearings are movably connected to both sides of the rear end surface of the cover, an oxygen tube is connected to the center position of the upper surface of the cover, a sleeve is sleeved on the lower surface of the oxygen tube, a connecting tube is connected to the bottom of the sleeve, oxygen supply tubes are connected to both sides of the surface of the connecting tube, a notch is opened at the center position of the lower surface of the cover, and both sides of the upper surface of the notch are parallel and corresponding to the position of the lower surface of the oxygen supply tube.

[0009] As a further improvement of the present technical solution, the sliding mechanism includes a groove, and sliding grooves are provided on both sides of the inner wall of the groove. A slider is slidably connected to the surface of the sliding groove. A rotating gear is installed at the center position of one side of the slider surface. An adjustment plate is connected to one side of the rotating gear surface. The adjustment plate is rotated and adjusted on one side of the slider surface through the rotating gear, and the cover is synchronously driven to rotate and adjust.

[0010] As a further improvement of the present technical solution, the adjusting mechanism includes a pressing rod, an inner lining plate is installed on the bottom surface of the pressing rod, clamping parts are installed on both sides of the surface of the inner lining plate, and hooks are installed on both sides of the surface of the cover. The upper surface of the pressing rod is connected to the lower surface of the slider correspondingly, and a through groove is opened on the lower surface of the groove, and the through groove is telescopically clamped to the inner lining plate correspondingly.

[0011] As a further improvement of the present technical solution, the cover is rotated by the bearing, and drives the hook to engage with the connecting piece accordingly. The position of the cover is adjusted by sliding the slider on the surface of the slide groove from the right side of the surface of the nose bridge sticker. After sliding to the upper surface of the patient's nose tip, the angle of the adjustment plate and the cover is adjusted by rotating the gear and the bearing, and the right side of the lower surface of the cover is aligned with the surface of the patient's nose. Then, the oxygen supply tubes arranged on the left and right sides of the inside of the cover can be connected to the inner side of the patient's nose to achieve the effect of supplying oxygen to the patient.

[0012] As a further improvement of the technical solution, the inner lining plate is telescopically and slidably adjusted on the lower surface of the groove through a slider. The inner lining plate extends from the lower surface of the nose bridge sticker and can be snap-fitted with one side of the cover surface to form a sealing state between the cover and the inner lining plate. When the cover supplies oxygen to the patient's nose, oxygen leakage from both sides above the patient's nose is prevented.

[0013] As a further improvement of the present technical solution, the nose bridge patch is fastened by means of an elastic band and a buckle. After the nose bridge patch is snapped onto the surface of the patient's nose, the nose bridge patch is tightened and adjusted by means of the elastic band and the buckle, so that it can be more comfortably snapped onto the surface of the patient's nose, and is easy and convenient to wear.

[0014] As a further improvement of the present technical solution, two groups of oxygen supply tubes are provided, and the two groups of oxygen supply tubes are symmetrically distributed on the left and right sides inside the cover, and the two groups of oxygen supply tubes are connected to the oxygen tubes through the sleeve and the connecting tube. The nose bridge patch is attached to the surface of the patient's nose, and then the nose bridge patch is fastened to the surface of the patient's nose through the elastic band and the buckle. After the cover is adjusted to correspond to the position of the patient's nose bridge, the medical staff or the accompanying personnel connect the oxygen tube to the external oxygen supply equipment accordingly, and the oxygen is introduced from the oxygen tube into the sleeve, and the oxygen is transmitted to the position of the oxygen supply tube through the connecting tube. Since the oxygen supply tubes are arranged on the left and right sides inside the cover, when the cover is snapped on the surface of the patient's nose, the oxygen supply tubes can be directly connected to the patient's nose, so that the patient can be directly supplied with oxygen, and the operation is convenient and simple.

[0015] As a further improvement of the present technical solution, the inner lining plate and the adjustment plate are synchronously raised and lowered and adjusted by the slider and the pressing rod, and are correspondingly engaged by the clamping parts and the hooks. After the cover is aligned with the surface position of the patient's nose, the slider slides downward on the surface of the slide groove and contacts the upper surface of the pressing rod. Under the action of extrusion, the inner lining plate is squeezed out from the center position of the lower surface of the nose bridge sticker, and the inner lining plate is attached to the surface of the patient's nose tip. At the same time, under the rotation adjustment of the bearing, the cover can make the hooks installed on both sides of the cover surface tilt synchronously, so that they can be engaged with the clamping parts installed on the surface of the inner lining plate, and then the cover as a whole can be fastened and engaged to the surface of the patient's nose.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The anti-pressure injury ventilator mask attaches a nose patch to the patient's nose bridge, and then fastens the nose patch to the surface of the patient's nose bridge through an elastic band and a buckle, thereby reducing the coverage of the mask on the patient's face and facilitating the installation of the mask on the patient's face. The operation is convenient and simple, so that when the patient turns over, the mask is squeezed on one side and deformed, causing friction or pressure on the patient's face, resulting in the risk of pressure injury.

[0018] 2. The anti-pressure injury ventilator mask, after the nose bridge is fastened to the patient's face, the medical staff or the accompanying personnel slide the slider downward on the surface of the slide groove to move the adjustment plate downward as a whole. Since the lower surface of the adjustment plate is connected to the two sides of the cover surface through the bearing, the cover can slide downward synchronously, and the angle of the cover can be adjusted by rotating the gear to make the groove opened at the center of the lower surface of the cover fit with the patient's nose tip position, so that the patient's nose tip position and the cover surface fit comfortably, so as to cope with patients with different nose bridge heights, and the applicability is stronger.

[0019] 3. The anti-pressure injury ventilator mask slides downward through the slider and contacts the lower surface of the pressing rod. Under the action of squeezing, the inner lining plate is effectively extended from the center position of the lower surface of the nose bridge to fit and cover the surface of the patient's nose tip. At the same time, the provided clips are extended, and after the cover is adjusted in angle and aligned with the patient's nostrils, the hooks provided on both sides of the cover surface are also bent synchronously, and then snap-fitted with the surface of the clips, effectively fastening the cover as a whole to the surface of the inner lining plate, achieving the effect of snap-fitting and fastening, and ensuring the patient's normal oxygen inhalation operation.

[0020] 4. The anti-pressure injury ventilator mask is configured such that after the cover is clamped and fastened to the patient's nose, the oxygen tube is arranged to transmit oxygen to the oxygen supply tube through the sleeve and the connecting tube, so that the patient can achieve the effect of oxygen inhalation.

[0034] The mask mechanism 100 is used to clamp the cover 102 onto the patient's facial surface, the adjustment plate 205 provided on the sliding mechanism 200 is used to adjust the position of the cover 102, and the bearing 106 is used to adjust the angle of the cover 102, so that the cover 102 is effectively rotated and clamped onto the patient's nasal surface to transmit oxygen to the patient's nasal position. At the same time, the adjustment mechanism 300 provided can clamp and fix the cover 102 as a whole onto the patient's nasal surface, so that the lower surface of the cover 102 fits with the patient's nose tip position, so that the patient's nose tip position fits comfortably with the surface of the cover 102, so as to cope with patients with different nose bridge heights, and the applicability is stronger.

[0035] according to Figure 1 , Figure 5-Figure 6 As shown, considering the need to realize the installation function of the mask mechanism 100, in this embodiment, the mask mechanism 100 includes a nose bridge sticker 101, elastic bands 104 are connected to the two ends of the left side of the surface of the nose bridge sticker 101, and a buckle 105 is connected to one side of the surface of the elastic band 104. A cover 102 is installed at the center position of the right side of the surface of the nose bridge sticker 101, and bearings 106 are movably connected to both sides of the rear end surface of the cover 102. An oxygen tube 103 is connected to the center position of the upper surface of the cover 102, and a sleeve 107 is sleeved on the lower surface of the oxygen tube 103. A connecting pipe 108 is connected to the bottom of the sleeve 107, and oxygen supply pipes 109 are connected to both sides of the surface of the connecting pipe 108. A notch is opened at the center position of the lower surface of the cover 102, and both sides of the upper surface of the notch are parallel to and corresponding to the position of the lower surface of the oxygen supply pipe 109;

[0036] Furthermore, by attaching the nose bridge patch 101 to the surface of the patient's nose, and then fastening the nose bridge patch 101 to the surface of the patient's nose through the elastic band 104 and the buckle 105, after the cover 102 is adjusted to avoid being corresponding to the position of the patient's nose bridge, the medical staff or the accompanying staff connects the oxygen tube 103 to the external oxygen supply device, and then the oxygen is introduced from the oxygen tube 103 into the sleeve 107, and the oxygen is transmitted to the position of the oxygen supply tube 109 through the connecting tube 108. Since the oxygen supply tube 109 is arranged on the left and right sides of the cover 102, when the cover 102 is snapped on the surface of the patient's nose, the oxygen supply tube 109 can be directly connected to the patient's nose, so the oxygen supply operation can be directly performed on the patient, and the operation is convenient and simple;

[0037] The improvement lies in that the nose patch 101 can be directly attached to the surface of the patient's nose, and the nose patch 101 and the cover 102 are fastened and clamped to the surface of the patient's nose through the elastic band 104 and the buckle 105, replacing the respiratory mask that covers a large area of ​​the patient's face, reducing the friction and compression on the surface of the respiratory mask when the patient turns his head, reducing the risk of pressure injury to the patient's face, and having a certain protective effect on the patient's face.

[0038] according to Figure 2-Figure 3 As shown, considering the need to realize the sliding effect of the sliding mechanism 200, in this embodiment, the sliding mechanism 200 includes a groove 201, and sliding grooves 202 are provided on both sides of the inner wall of the groove 201. A slider 203 is slidably connected to the surface of the sliding groove 202. A rotating gear 204 is installed at the center position of one side of the surface of the slider 203. An adjusting plate 205 is connected to one side of the surface of the rotating gear 204. The adjusting plate 205 is rotated and adjusted on one side of the surface of the slider 203 through the rotating gear 204, and synchronously drives the cover 102 to rotate and adjust;

[0039] Furthermore, after the medical staff or accompanying staff align the cover 102 with the patient's nose, the slider 203 slides downward on the surface of the slide groove 202, and the adjustment plate 205 slides downward synchronously. After the lower surface of the cover 102 contacts the position of the patient's nose tip, the angle of the adjustment plate 205 can be adjusted by rotating the gear 204, and the adjustment plate 205 is raised. Since the front end of the surface of the adjustment plate 205 is connected to the surface of the cover 102 via the bearing 106, the position and angle of the cover 102 can be adjusted synchronously, so that the lower surface of the cover 102 slides in close contact with the surface of the patient's nose tip.

[0040] The improvement lies in that the position of the cover 102 is adjusted by sliding the slider 203 on the surface of the slide groove 202 from the right side of the surface of the nose bridge sticker 101. After sliding to the upper surface of the patient's nose tip, the angle of the adjustment plate 205 and the cover 102 is adjusted by rotating the gear 204 and the bearing 106, so that the right side of the lower surface of the cover 102 is aligned with the position of the patient's nose surface, and then the oxygen supply tubes 109 arranged on the left and right sides of the cover 102 can be connected to the inner side of the patient's nose to achieve the effect of supplying oxygen to the patient.

[0041] according to Figure 4 As shown, considering the need to realize the adjustment function of the adjustment mechanism 300, in this embodiment, the adjustment mechanism 300 includes a pressing rod 301, an inner lining plate 302 is installed on the bottom surface of the pressing rod 301, and clamping members 303 are installed on both sides of the surface of the inner lining plate 302, and hooks 304 are installed on both sides of the surface of the cover 102. The upper surface of the pressing rod 301 is connected to the lower surface of the slider 203, and a through groove is opened on the lower surface of the groove 201, and the through groove is telescopically clamped with the inner lining plate 302;

[0042] Furthermore, after the cover 102 is aligned with the position of the patient's nose surface, the slider 203 slides downward on the surface of the slide groove 202 and contacts the upper surface of the pressing rod 301. Under the action of squeezing, the inner lining plate 302 is squeezed out from the center position of the lower surface of the nose bridge sticker 101, and the inner lining plate 302 is attached to the surface of the patient's nose tip. At the same time, under the rotation adjustment of the bearing 106, the cover 102 can make the hooks 304 installed on both sides of the cover 102 surface tilt synchronously, so that they can be correspondingly engaged with the engaging parts 303 installed on the surface of the inner lining plate 302, and then the cover 102 can be fastened and engaged to the patient's nose surface as a whole.

[0043] The improvement lies in that after the inner side of the cover 102 is snapped onto the surface of the patient's nose, the angle of the surface of the cover 102 is adjusted. After the cover 102 is comfortably snapped onto the surface of the patient's nose, the inner lining plate 302 is extended from the center position of the lower surface of the nose patch 101 under the squeezing action of the pressing rod 301, and is snapped into correspondence with the snap-in piece 303 installed on the surface of the inner lining plate 302 through the provided hook 304, so that the cover 102 can be fastened and snapped onto the surface of the patient's nose as a whole, playing a fixing role and ensuring the patient's normal oxygen inhalation operation, and the inner lining plate 302 extends from the lower surface of the nose patch 101, and can be snapped into correspondence with one side of the surface of the cover 102, so that a sealed state is formed between the cover 102 and the inner lining plate 302, and when the cover 102 supplies oxygen to the patient's nose for oxygen inhalation, oxygen leakage from both sides above the patient's nose is prevented.

[0044] In summary, the working principle of this solution is as follows: attach the nose bridge patch 101 to the patient's nose bridge, and then fasten the nose bridge patch 101 to the surface of the patient's nose bridge through the elastic band 104 and the buckle 105, so as to reduce the coverage of the mask on the patient's face, and at the same time facilitate the installation of the mask on the patient's face, and the operation is convenient and simple, so that when the patient turns over, the mask is squeezed on one side and deformed, causing friction or pressure on the patient's face, and there is a risk of pressure injury. After fastening the nose bridge patch 101 to the patient's face, the medical staff or the accompanying caregiver The personnel slide the slider 203 downward on the surface of the slide groove 202 to move the adjustment plate 205 downward as a whole. Since the lower surface of the adjustment plate 205 is connected to both sides of the surface of the cover 102 through the bearing 106, the cover 102 can slide downward synchronously, and the angle of the cover 102 can be adjusted by rotating the gear 204, so that the notch opened at the center of the lower surface of the cover 102 fits with the position of the patient's nose tip, so that the patient's nose tip fits comfortably with the surface of the cover 102, so as to cope with patients with different nose bridge heights, and the applicability is stronger;

[0045] The slider 203 slides downward and contacts the lower surface of the pressing rod 301. Under the effect of squeezing, the inner lining plate 302 is effectively extended from the center position of the lower surface of the nose bridge sticker 101 to fit and cover the surface of the patient's nose tip. At the same time, the provided clamping piece 303 is extended. After the cover 102 is adjusted in angle and aligned with the patient's nostrils, the hooks 304 provided on both sides of the cover 102 surface are also bent synchronously, and then clamped with the surface of the clamping piece 303, effectively fastening the cover 102 as a whole to the surface of the inner lining plate 302, achieving the effect of clamping and fastening, and ensuring the patient's normal oxygen inhalation operation. After the cover 102 is clamped and fastened to the patient's nose, the provided oxygen tube 103 transmits oxygen to the oxygen supply tube 109 through the sleeve 107 and the connecting tube 108, and the patient can achieve the effect of oxygen inhalation.
