Description

Technical Field

[0001] The invention relates to the technical field of medical supplies, in particular to a nasal oxygen tube set. Background Art

[0002] Nasal oxygen cannula is a common medical consumable made of polyvinyl chloride or polyurethane, used to deliver oxygen to the patient's nasal cavity to provide respiratory support. Nasal oxygen cannula on the market consists of an oxygen supply line and a fixing component. The length of the oxygen supply line is 1.5-2m, the inner diameter is 2-6mm, one end is an air source connector connected to the oxygen source, and the other end is a nasal plug. The common fixing component is an elastic fixing belt, which is wrapped around the back of the patient's head and is used to position the nasal plug at the patient's nostrils. The elastic fixing belt is slender and contacts the patient's auricle or face for a long time, which is prone to pressure sores; when the patient lies on his side, the elastic fixing belt is easy to curl, causing the nasal plug to shift and fall off easily. The movement of the oxygen cannula of the nasal plug in the nostrils will also increase the patient's discomfort. In severe cases, the oxygen cannula will fall off from the nostrils and affect the oxygen supply effect.

[0003] In order to solve the above technical problems, various solutions have been proposed in the prior art. Chinese patent document CN211658998U discloses an oxygen tube, which is provided with a limit sleeve on the outside of the oxygen cannula to increase the volume of the end of the oxygen cannula, and further provided with a nose clip. The added nose clip can make the oxygen cannula more firmly placed in the patient's nasal cavity to prevent it from falling off during use. Chinese patent document CN212187393U discloses an ear-hook wearable nasal oxygen cannula, which is fixed with an aluminum nose clip and a silicone ear hook. When worn, the two silicone ear hooks are hung on the patient's ears respectively. Because it uses ultra-strong tensile soft silicone material, it feels delicate and smooth, and is not easy to cause local skin redness, allergies, ulcers and other discomforts. At the same time, the aluminum nose clip clamps the nose bridge to ensure that the oxygen tube will not fall off. Chinese patent document CN213252222U discloses a device for wearing a high-flow nasal oxygen inhalation nasal plug, which is intended to solve the technical problem that the fixing belt in the prior art is too thin, long-term compression of the human face, and easy to cause pressure sores on the skin of the occipital part of the face. The nasal congestion fixing belt includes a support frame and a fabric belt, the support frame is made of titanium alloy material, and the fabric belt is made of high-elastic knitted fabric. The end of the support frame close to the face is like the wearing method of glasses, and the hardness of the support frame can be used to reduce the pressure on the human face. The fabric belt further provided can increase the contact area between the nasal congestion fixing belt and the human face, thereby reducing the pressure of the nasal congestion fixing belt on the human face and improving comfort. Chinese patent document CN219127816U discloses a high-frequency oxygen inhalation device for patients with open mouth breathing, including a nasal catheter body, the nasal catheter body has an oxygen catheter, a nasal suction tube part, and a joint. The oxygen inhalation device also includes a strap body, the strap body includes a face contact part, and the upper and lower sides of the face contact part are respectively concave to form an arc-shaped edge. Elastic bands are bonded to both sides of the nasal suction tube part, and the other end of the elastic band is detachably connected to the face contact part, and the oxygen catheter is detachably fitted and fixed to the face contact part. This scheme helps to fix the oxygen inhalation tube in the patient's nasal cavity, but its strap body wraps most of the area of ​​the patient's head, which will cause discomfort to the patient. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a nasal oxygen cannula set, so as to reduce the probability of large displacement between the oxygen cannula and the patient's nostrils and improve the patient's comfort.

[0005] In order to achieve the above object, the technical solution of the present invention is as follows:

[0006] Nasal oxygen cannula set, including

[0007] The nasal oxygen cannula has a nasal plug part, which is provided with 1-2 oxygen supply cannulas for inserting into the patient's nostrils;

[0008] A fixing component, used for fixing the nasal plug part to the patient's head;

[0009] The fixing assembly comprises a nose bridge patch; the nose bridge patch has a middle bulge along its length direction to adapt to the shape of the nose bridge, a clamping portion connected to the crossbar of the eyeglass frame at the top, side wings extending toward both sides to be pressed by the nose pads of the eyeglass frame at the upper part, and a bottom connected to the nose plug part;

[0010] The clamping portion has a downward beam clamping hole, which is formed by curling the clamping portion toward the middle protrusion; after the beam clamping hole is connected to the frame beam, when the nose bridge patch has a downward trend along the nose bridge, the beam clamping hole presses the top of the frame beam.

[0011] The invention concept of the present invention is to replace the existing elastic fixing belt or wrapping belt with a spectacle frame to assist in fixing the nasal obstruction. The spectacle frame can be the patient's own myopia spectacle frame, or a temporary cheap spectacle frame can be configured separately. Compared with the elastic fixing belt or wrapping belt, the spectacle frame will not produce a large area of ​​close contact with the patient's head skin, has good air permeability, and is relatively comfortable to use. For patients who wear glasses for a long time, their discomfort will be further reduced.

[0012] The present application uses a nose bridge patch to connect the eyeglass frame and the nasal oxygen tube. The nose bridge patch has positioning points on the top, bottom, left and right sides, and is not prone to slippage, so it has a better fixing effect on the nasal obstruction. Specifically, the bottom fixing point of the nose bridge patch is the connection point between it and the nasal obstruction part, the top fixing point is the connection point between it and the crossbeam of the frame, and the left and right fixing points are the pressure of the nose pads on both sides of the eyeglass frame on the side wings of the nose bridge patch. In addition, the shape of the nose bridge patch is adapted to the shape of the nose, and there is a certain friction between it and the nose bridge, so that the nose bridge patch is not easy to move after positioning, and the probability of large displacement between the oxygen cannula and the patient's nostrils is low.

[0013] Secondly, compared with the nose clip in the prior art, the nose patch does not produce a clamping force on the nose bridge and is more comfortable. The side wings of the nose patch are pressed by the nose pads of the glasses frame, and the middle protrusion of the nose patch makes the probability of the nose patch shifting left and right lower, which helps to improve the stability of the nose patch. Secondly, under the premise that the glasses frame and the patient's head do not shift, the nose patch clipped thereto will not slide downward. The downward crossbeam clip is formed by the clip portion curling toward the direction of the middle protrusion. When the nose patch has a downward trend, it exerts an inward and downward force on the crossbeam of the frame, which helps to stabilize the glasses frame.

[0014] As another structure based on the same inventive concept, its snap-fitting portion has an upward beam snap-fit, and the beam snap-fit ​​is formed by extending the snap-fitting portion toward the middle protrusion and then curling inward; after the beam snap-fit ​​is connected to the beam of the frame, when the nose bridge patch tends to slide down along the nose bridge, the beam snap-fit ​​presses the bottom of the beam of the frame.

[0015] This solution produces an upward crossbeam snap-in. When the nose bridge patch has a downward tendency to slide down, it exerts an inward and downward force on the frame crossbeam, preventing the temples of the glasses from curling up due to the force on the frame crossbeam, which helps to improve the stability of the glasses frame.

[0016] As another structure based on the same inventive concept, the clamping part is a foldable metal sheet. This solution has strong adaptability and mobility. According to the patient's facial shape, the metal sheet can be bent into a hook for hooking the crossbeam of the frame before use to achieve the top positioning of the nose bridge patch.

[0017] As an improvement, the nasal oxygen cannula kit also includes an eyeglass frame having a frame crossbar and a nose pad. A low-cost eyeglass frame can be provided with the kit, and if the patient has his own glasses, the patient can choose to use his original glasses.

[0018] As a further improvement, the glasses frame is provided with a tube buckle that can be temporarily fixed with the nasal oxygen tube. The nasal oxygen tube is buckled on the glasses frame, and the movement or shaking of the nasal oxygen tube is not easy to affect the nasal congestion part, which helps to improve the stability of the nasal congestion part.

[0019] As a further improvement, the catheter buckle is located at the end of the temple of the eyeglass frame. If the catheter buckle is located at the front end of the temple, the movement or shaking of the nasal oxygen tube will cause the eyeglass frame to shake. The catheter buckle is located at the end of the temple, and the movement or shaking of the nasal oxygen tube not only has less impact on the front end of the eyeglass frame, but also helps to stabilize the temple on the patient's ear, thereby improving the stability of the connection between the eyeglass frame and the patient's face.

[0020] As an improvement, the nose bridge patch and the nasal oxygen tube are separately arranged and can be detachably connected before use. Generally speaking, the nose bridge patch and the nasal oxygen tube are made of raw materials of different materials, and the two need to be produced separately. Of course, the two can also be fixedly connected after being produced separately.

[0021] As a further improvement, the nose bridge patch is provided with at least one connecting hole at its bottom along its length direction, and a connecting column for snapping with the connecting hole is provided on the nasal plug part.

[0022] As an alternative solution, the nose bridge patch and the nasal oxygen tube are separately arranged and can be detachably connected before use. A nose plug clamp for temporarily connecting to the nasal plug part is provided at the bottom of the nose bridge patch.

[0023] As a further improvement, the width of the crossbeam bayonet is 10-15 mm.

[0024] In summary, the present invention is based on a spectacle frame and utilizes a nose bridge patch provided with four positioning points, so that the nasal plug part of the nasal oxygen tube can be stably fixed at the patient's nostrils, which is more comfortable and helps to improve the oxygen supply effect.

DETAILED DESCRIPTION

[0038] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0039] Example 1

[0040] like Figure 1 As shown, the nasal oxygen cannula set of the present invention includes a nasal oxygen cannula 10, a nose bridge patch 20, and a glasses frame 30, and the three components are packed together in a packaging bag 40. Obviously, the packaging bag 40 can also only include the nasal oxygen cannula 10 and the nose bridge patch 20.

[0041] like Figure 2 As shown, the nasal oxygen tube 10 has a nasal plug part 11, and the nasal plug part 11 is provided with 1-2 oxygen supply cannulas 12 for inserting into the patient's nostrils. The fixing assembly for fixing the nasal plug part 11 to the patient's head includes a nose bridge patch 20 and a glasses frame 30. The nose bridge patch 20 is made of latex material, with a thickness of 1-2 mm, and has a middle bulge along its length direction to adapt to the shape of the nose bridge.

[0042] The nose bridge patch 20 has four positioning points, namely, top, bottom, left, and right, as follows:

[0043] (1) Top positioning point: The top of the nose bridge patch 20 has a snap-on portion 21 connected to the frame crossbeam 31 of the eyeglass frame 30. The snap-on portion 21 is made of hard latex material and has a downward crossbeam snap-on 211. The crossbeam snap-on 211 is formed by curling the snap-on portion 21 toward the middle protrusion, and its lateral width is 10-15 mm.

[0044] (2) Positioning points on the left and right sides: The upper part or the upper middle part of the nose bridge patch 20 has side wings 22 extending toward both sides for being pressed by the nose pads 32 of the eyeglass frame 30.

[0045] (3) Bottom positioning point: The bottom of the nose bridge patch 20 is connected to the nasal obstruction part 11.

[0046] The nose patch 20 and the nasal oxygen tube 10 are separately arranged and can be detachably connected before use. The detachable connection method is: the nose patch 20 is provided with two connection holes 23 at its bottom along its length direction, and the nasal plug part 11 is provided with a connection column 13 for snapping with the connection holes 23. Before use, the connection holes 23 are snapped onto the connection column 13 to achieve temporary fixation of the two. Obviously, by selecting different connection holes 23 to snap with the connection column 13, the position of the nose patch 20 on the nose bridge can be adjusted. Secondly, the nose patch 20 and the nasal plug part 11 can also be fixedly connected in advance during production.

[0047] After the crossbeam snap-in 211 is connected to the frame crossbeam 31, when the nose bridge patch 20 tends to slide down along the nose bridge, the crossbeam snap-in 211 presses the top of the frame crossbeam 31. At this time, the force direction of the clamping part is shown in Figure 3. In order to enhance the guidance of the force direction of the clamping part 21, the clamping part 21 is slightly tilted forward toward the middle bulge of the nose bridge patch 20, as shown in Figure 3. Figure 4 As shown, the forward tilt angle can be 2°. When the nose bridge patch 20 has a downward trend along the nose bridge, the inward and downward force of the frame crossbeam 31 is enhanced, which helps to enhance the stability of the eyeglass frame 30 on the patient's head. Figure 5 shown.

[0048] Example 2

[0049] like Figure 6 As shown, the difference between Example 2 and Example 1 is that the clamping portion 21 has an upward crossbeam clamping hole 211, which is formed by the clamping portion 21 extending toward the middle bulge and then curling inward. After the crossbeam clamping hole 211 is connected to the frame crossbeam 31, when the nose bridge patch 20 has a downward trend along the nose bridge, the crossbeam clamping hole 211 presses the bottom of the frame crossbeam 31. At this time, the frame crossbeam 31 is subjected to an inward and downward force, as shown in FIG. Figure 7 As shown, this force helps to enhance the stability of the eyeglass frame 30 on the patient's head.

[0050] Example 3

[0051] like Figure 8 As shown, the difference between Example 3 and Example 1 is that the clamping portion 21 is a foldable metal sheet, and the lateral width of the metal sheet is 10-15 mm. The metal sheet can be folded into a hook portion for hooking the frame crossbeam 31 according to the facial features of the patient. Since the bending point of the metal sheet can be selected at will, it has a certain degree of adjustability, and the connection holes 23 at the bottom of the nose bridge patch 20 are reduced from 2 to 1.

[0052] Example 4

[0053] like Fig. 9 As shown, the difference between Example 4 and Example 3 is that the detachable connection method between the nose bridge patch 20 and the nasal obstruction part 11 is different. This embodiment abandons the method of snapping the connection hole 23 with the connection column 13, and instead sets a nose plug clamp 24 for temporarily connecting the nasal obstruction part 11 at the bottom of the nose bridge patch 20. The nose plug clamp 24 is made of hard latex material and there are two of them. When in use, the nose plug clamp 24 clamps the two ends of the nasal obstruction part 11 to achieve the connection between the two.

[0054] Example 5

[0055] like Fig.10 , Fig.11As shown, the difference between Example 5 and Example 1 is that: the eyeglass frame 30 is provided with a catheter buckle 33 that can be temporarily fixed to the nasal oxygen tube 10, and the catheter buckle 33 can be sleeved on the end of the temple of the eyeglass frame 30. The use state of the set is as follows Fig.12 As shown, at this time, the movement or shaking of the nasal oxygen tube 10 has relatively little effect on the frame crossbeam 31 and the nose pad 32, and will also generate a downward pulling force on the ends of the temples of the eyeglass frame 30, which will in turn improve the stability of the connection between the eyeglass frame 30 and the patient's face.

[0056] It should be noted that the eyeglass frame 30 provided together with the nose bridge patch 20 is generally a frame without lenses, and in order to match the inventive concept of the present invention, the eyeglass frame 30 must have a frame crossbar 31 and a nose pad 32.
