Description

Technical Field

[0001] This invention relates to the field of oxygen supply equipment technology, and in particular to a convenient oxygen inhalation device. Background Technology

[0002] For patients with difficulty breathing or hypoxia, it is necessary to carry an oxygen bag when undergoing MRI examination to replenish oxygen at any time, relieve breathing difficulties, and maintain normal blood oxygen levels. Oxygen bags are lightweight, easy to carry, and simple to operate, making them suitable for temporary or short-term oxygen inhalation needs.

[0003] Traditional medical oxygen bags have shortcomings in clinical use. When worn, the nasal plug length is fixed, making it difficult to adjust the length of the plug entering the patient's nasal cavity, which can easily lead to discomfort. Furthermore, securing the oxygen tube by wrapping it behind the patient's ear for an extended period can cause pressure on the ear and restrict head movement, making it difficult to turn over or move the head. Additionally, the placement of the plastic flap on the oxygen tube is problematic. If the flap faces downwards, it can cause pressure sores or bruising, especially for long-term oxygen users. If it faces upwards, it doesn't secure the tube properly, increasing the risk of oxygen leakage. The flap can also easily detach during patient movements such as sitting up or turning over. Moreover, the pressure of ordinary oxygen bags decreases continuously during oxygen supply, requiring medical staff to manually press the bag, which is not only uneven in pressure but also time-consuming and laborious. Therefore, based on these problems, this invention provides a convenient oxygen delivery device to meet these needs. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a convenient oxygen inhalation device. This device incorporates a support component and a compression component, which are respectively mounted on the oxygen tubing and the oxygen bag. The support component not only improves the patient's comfort when wearing the oxygen tubing but also prevents the tubing from falling out during patient activity, thus avoiding the harm caused by a dislodged tubing. The compression component not only clamps and secures one end of the oxygen bag but also replaces manual pressure control to ensure normal oxygen output from the oxygen bag, guaranteeing both the demand and quality of oxygen supply. These features address the shortcomings of existing traditional medical oxygen bags in clinical use.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A portable oxygen inhalation device includes an oxygen inhalation tube and an oxygen bag. One end of the oxygen inhalation tube is fixedly connected to a support component, which helps prevent the oxygen inhalation tube from falling off during oxygen inhalation. The support component is connected to the oxygen inhalation tube. A squeezing component is used to ensure normal oxygen output from the oxygen bag. The squeezing component is connected to the oxygen bag.

[0007] Optionally, the support assembly includes ear loops symmetrically fitted onto the oxygen inhalation tube. Both ends of the oxygen inhalation tube are inserted into the nasal cavity through fixing plates. The fixing plates have symmetrical tube holes. A support frame is fixedly installed on one side of the fixing plates. The support frame is an elastic structure and has evenly spaced adjustment grooves.

[0008] Optionally, the ear hook is a curved elastic structure, the bottom of the ear hook is uniformly provided with weakening grooves, and the inner wall size of the ear hook matches the outer wall size of the oxygen inhalation tube.

[0009] Optionally, the bottom ends of the fixing piece are symmetrically provided with partial folds, and the bottom of the center of the fixing piece has an arc-shaped structure that is recessed toward the middle of the fixing piece.

[0010] Optionally, the compression assembly includes a clamping tube clamping one end of the oxygen bag, a knob fixedly connected to one end of the clamping tube, a compression clamp sleeved on the outer wall of the clamping tube, two symmetrically upward-curved flanges at one end of the compression clamp, limit springs symmetrically fixedly connected to the inner wall of the compression clamp, a clamping spring fixedly connected to the other end of the compression clamp, an opening on one side of the clamping spring, and a handle groove extending through the clamping spring.

[0011] Optionally, a clamping slit is provided on one side of the clamping tube, and symmetrical protrusions are provided at the bottom of both sides of the clamping slit, with the distance between the protrusions being less than the end thickness of the oxygen bag.

[0012] Optionally, the extrusion clamp, the limiting spring, and the clamping spring are integrally manufactured and have a curved elastic structure as a whole. Lightweight grooves are uniformly formed on the limiting spring, and the limiting spring has a curved elastic structure.

[0013] Optionally, the compression clamp has an insertion slot at one end of the flanged portion, and the gap between the insertion slots is greater than the end thickness of the oxygen bag.

[0014] Optionally, a flow regulating valve is fitted onto the oxygen inhalation tube, and a humidifying filter is fixedly connected to the oxygen inhalation tube near its bottom. The bottom of the humidifying filter is connected to the oxygen bag through the oxygen inhalation tube.

[0015] Optionally, the curvature and size of the flanged portion match the outer contour dimensions of the humidifying filter element.

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

[0017] In the above solution, by setting up a support component and a compression component, which are respectively installed on the oxygen tubing and the oxygen bag, the support component can not only improve the comfort of the patient wearing the oxygen tubing, but also ensure that the oxygen tubing is not easily dislodged during the patient's activities, thereby avoiding the harm caused by the oxygen tubing falling off; the compression component can not only clamp and fix one end of the oxygen bag, but also replace manual hand pressure to control the oxygen supply pressure, ensuring the normal output of oxygen in the oxygen bag and ensuring the demand and quality of oxygen supply.

[0018] By setting up a support frame and a fixing plate, and using the adjustment groove for easy bending, the support frame can be made to fit the patient's nose. The fixing plate can prevent oxygen leakage, allowing the oxygen tube to enter the nasal cavity suspended. The length of the oxygen tube suspended in the nasal cavity can also be adjusted arbitrarily, greatly reducing irritation to the nasal mucosa and making oxygen inhalation more comfortable for patients, thus greatly improving the patient's comfort level.

[0019] By incorporating ear hooks, discomfort caused by prolonged wear can be avoided. The ear hooks are flexible and feature evenly distributed grooves at the bottom, facilitating adjustment of the curvature and reducing their weight for a more portable design. Furthermore, the ear hooks are directly attached to the oxygen tubing, allowing for easy disassembly and height adjustment to suit different patient postures. The curved bottom of the ear hooks also helps adjust the tightness of the oxygen tubing between the nasal cavity and the ear hook.

[0020] By using a combination of a squeezing clamp, a clamping tube, and a limiting spring, the oxygen bag is held in place by the clamping tube. By manually rotating the knob, the oxygen bag is sequentially wound into the squeezing clamp 11 through the squeezing clamp and the limiting spring, thereby controlling the oxygen supply pressure of the oxygen bag. The structure is not only simple and ingenious, but also convenient and labor-saving in actual operation. In addition, the squeezing clamp and the limiting spring are manufactured as a single unit, which makes the processing technology of the three components simpler and easier to manufacture, reducing the manufacturer's capital investment.

[0021] By using a combination of clamping springs and a handle groove, the oxygen bag can be in two states: the clamping springs allow for easy fixation to the bed rails, holding the oxygen bag in place; when the oxygen bag needs to be taken out, the handle groove allows the patient or caregiver to easily carry the oxygen bag. This fixing method using clamping springs is not only simple and inexpensive, but also highly efficient. Attached Figure Description

[0040] like Figures 1 to 9As shown, an embodiment of the present invention provides a convenient oxygen inhalation device, including an oxygen inhalation tube 1 and an oxygen bag 10. The oxygen inhalation tube 1 is connected to the oxygen bag 10. One end of the oxygen inhalation tube 1 is fixedly connected to a support component, which is used to help prevent the oxygen inhalation tube 1 from falling off during oxygen inhalation. A squeezing component is used to ensure normal output of oxygen from the oxygen bag 10. The squeezing component is connected to the oxygen bag 10. A flow regulating valve 8 is sleeved on the oxygen inhalation tube 1. A humidifying filter element 9 is fixedly connected near the bottom of the oxygen inhalation tube 1. The bottom of the humidifying filter element 9 is connected to the oxygen bag 10 through the oxygen inhalation tube 1.

[0041] The portable oxygen inhalation device provided by this invention is suitable for patients' temporary or short-term oxygen inhalation needs. The oxygen tubing 1 passes between the compression disc and compression plate of the flow regulating valve 8. When using the flow regulating valve, first rotate the adjusting knob counterclockwise to adjust the distance between the compression disc and compression plate to the maximum. At this point, the distance between the compression disc and compression plate is exactly the outer diameter of one oxygen tubing 1. Push the oxygen tubing 1 towards the anti-dislodgement hook, which applies pressure to the anti-dislodgement pin, causing it to collapse and allowing the oxygen tubing 1 to smoothly enter between the compression disc and compression plate. When the oxygen tubing 1 has no pressure on the release hook, the anti-detachment pin resets under the action of the return spring, restricting the position of the oxygen tubing 1. Then, by turning the adjusting knob clockwise, the distance between the squeezing disc and the squeezing plate gradually decreases, and the oxygen tubing 1, stuck between the squeezing plate and the squeezing disc, is gradually squeezed, reducing its cross-sectional area and thus regulating the oxygen bag flow rate. The degree of squeezing of the oxygen tubing 1 by this flow regulating valve can be arbitrarily controlled from 0% to 100%. The flow regulating valve 8 has an internal threaded self-locking mechanism for stable control. The pressure applied to the oxygen tubing 1 will not be affected by excessive air pressure. The working principle of the flow regulating valve 8 on the oxygen tubing 1 is disclosed as prior art and will not be elaborated further. By setting a humidifying filter 9, the humidity of the oxygen is increased, avoiding the irritation of the respiratory tract by dry oxygen. The multi-layer structure and pleated design inside the humidifying filter 9 increase the contact area between water and air, making it easier for water molecules to evaporate when passing through the filter, forming humidified oxygen. The working principle of the humidifying filter 9 on the oxygen tubing 1 is disclosed as prior art and will not be elaborated further. By setting a support component and a compression component, which are respectively set on the oxygen tubing 1 and the oxygen bag 10, the support component can not only improve the comfort of the patient wearing the oxygen tubing 1, but also ensure that the oxygen tubing 1 is not easily dislodged during the patient's activities, thereby avoiding the harm caused by the oxygen tubing 1 falling off. The compression component can not only clamp and fix one end of the oxygen bag 10, but also replace manual hand pressure to control the oxygen supply pressure, ensuring the normal output of oxygen in the oxygen bag 10 and ensuring the demand and quality of oxygen supply.

[0042] like Figures 1 to 5As shown, the support assembly includes ear loops 2 symmetrically fitted onto the oxygen tube 1. Both ends of the oxygen tube 1 are inserted into the nasal cavity through fixing pieces 4. The fixing pieces 4 have symmetrically opened tube holes 5. A support frame 6 is fixedly installed on one side of the fixing piece 4. The support frame 6 is an elastic structure with evenly distributed adjustment grooves 7. The ear loops 2 are curved elastic structures with evenly distributed weakening grooves 3 at the bottom. The inner wall dimensions of the ear loops 2 match the outer wall dimensions of the oxygen tube 1. The bottom ends of the fixing pieces 4 have symmetrical partial folds with tube holes 5. The tube holes 5 on the partial folds on the same side correspond to the tube holes 5 on the fixing pieces 4. The bottom center of the fixing pieces 4 has an arc-shaped structure concave towards the center of the fixing pieces 4. The ear loops 2 are made entirely of medical-grade silicone, possessing good elasticity and flexibility. The silicone material allows it to conform well to the skin surface when in contact with the skin, reducing pressure. The overall curved contour of the ear hook 2 conforms to the auricle structure for a better fit. Patients can adjust it according to their ear size and shape to further improve wearing comfort. The ear hook 2 prevents ear discomfort caused by prolonged wear. The curvature of the ear hook 2 is flexible, and the bottom of the ear hook 2 has evenly distributed weakening grooves 3, which facilitates adjustment of the curvature and reduces the weight of the ear hook 2, making the structure lighter. In addition, the ear hook 2 is directly attached to the oxygen tube 1, and can be easily removed or adjusted in height to suit different patient postures. The curved bottom of the ear hook 2 makes it easy to adjust the tightness of the oxygen tube 1 between the nasal cavity and the ear hook 2.

[0043] The fixation plate 4 has symmetrically arranged tube holes 5. The oxygen tube 1 passes through the tube hole 5 at the bottom of one side of the fixation plate 4 and enters the patient's nasal cavity. The inner wall size of the tube hole 5 matches the outer wall size of the oxygen tube 1, so that the tube hole 5 can fix the position of the oxygen tube 1. The position of the oxygen tube 1 between the upper and lower tube holes 5 on the same side of the fixation plate 4 and the partial fold allows the oxygen tube 1 to be suspended in the nasal cavity for a certain length. The thin design of the fixation plate 4 can prevent oxygen leakage and ensure the overall structure is lightweight. The support frame 6 is a flexible structure that can be bent freely to adapt to the nasal contours of different patients and ensure the comfort of the patient. By setting the support frame 6 and the fixation plate 4, and using the adjustment groove 7 to facilitate bending, the support frame 6 can fit the patient's nose. The fixation plate 4 can prevent oxygen leakage, allow the oxygen tube 1 to be suspended in the nasal cavity, and arbitrarily adjust the length of the oxygen tube 1 suspended in the nasal cavity, greatly reducing the irritation to the nasal mucosa and allowing the patient to breathe oxygen more comfortably, thus greatly improving the patient's comfort during oxygen inhalation.

[0044] like Figures 6 to 9As shown, the compression assembly includes a clamping tube 20 clamped at one end of the oxygen bag 10. A knob 19 is fixedly connected to one end of the clamping tube 20. A compression clamp 11 is sleeved on the outer wall of the clamping tube 20. One end of the compression clamp 11 has two symmetrically upward-curved flanges 13. A limit spring 14 is symmetrically fixedly connected to the inner wall of the compression clamp 11. A clamping spring 17 is fixedly connected to the other end of the compression clamp 11. An opening 16 is opened on one side of the clamping spring 17. A handle groove 18 is opened through the clamping spring 17. A clamping slot 21 is opened on one side of the clamping tube 20. Protrusions 22 are symmetrically provided at the bottom of both sides of the clamping slot 21. The space between the protrusions 22 is... The distance is less than the end thickness of the oxygen bag 10. The compression clamp 11, the limiting spring 14 and the clamping spring 17 are integrally manufactured structures and the whole is a curved elastic structure. Lightweight grooves 15 are evenly opened on the limiting spring 14. The limiting spring 14 is a curved elastic structure. One end of the compression clamp 11 with the flange 13 is provided with an insertion slot 12, that is, an insertion slot 12 is formed between the two flanges 13. The gap between the insertion slots 12 is greater than the end thickness of the oxygen bag 10. The curvature and size of the flange 13 match the outer contour size of the humidifying filter element 9. The clamping tube 20 is placed inside the compression clamp 11 and the position of the insertion slot 12 corresponds to the position of the clamping slot 21.

[0045] Specifically, one end of the oxygen bag 10 is inserted into the clamping slit 21 through the insertion slit 12, and the protrusion 22 clamps the oxygen bag 10. During the patient's oxygen inhalation, as the amount of oxygen inside the oxygen bag 10 decreases, the oxygen supply pressure of the oxygen bag 10 decreases accordingly. By manually rotating the knob 19, the end of the oxygen bag 10 is wound between the clamping tube 20 and the limiting spring 14, thereby adjusting the oxygen supply pressure inside the oxygen bag 10 and ensuring normal oxygen output. Due to the elastic structure of the limiting spring 14, under the action of elasticity, the limiting spring 14 can undergo elastic deformation under the compression of the oxygen bag 10, and can use its own elasticity to generate secondary compression of the oxygen bag 10, which facilitates the fixation of the position of the oxygen bag 10. The distance between the insertion slits 12 is only slightly larger than the maximum distance between the insertion slits 12. The thickness of the oxygen bag 10 facilitates the full compression of oxygen, ensuring oxygen utilization while also making the oxygen bag 10 smaller in size after storage, making it convenient for storage and carrying. By setting up a compression clamp 11, a clamping tube 20, and a limiting spring 14, the oxygen bag 10 is clamped by the clamping tube 20. By manually rotating the knob 19, the oxygen bag 10 is rolled into the compression clamp 11 in sequence through the compression clamp 11 and the limiting spring 14, thereby controlling the oxygen supply pressure of the oxygen bag 10. Not only is the structure simple and ingenious, but it is also convenient and labor-saving in actual operation. In addition, the compression clamp 11 and the limiting spring 14 are manufactured as a single piece, which makes the processing technology of the three parts simpler and easier to manufacture, reducing the manufacturer's capital investment.

[0046] The oxygen inhalation tube 1 is fixedly connected to a humidifying filter 9 near its bottom. The bottom of the humidifying filter 9 is connected to the oxygen bag 10 through the oxygen inhalation tube 1. The humidifying filter 9 is clamped onto the two symmetrically curved flanges 13 at one end of the compression clamp 11. The outer contour curvature of the humidifying filter 9 matches the curvature of the flanges 13. The flange structure of the compression clamp 11 facilitates the clamping and fixing of the humidifying filter 9. Furthermore, the curved elastic structure of the flanges 13 makes the humidifying filter 9 easy to disassemble and replace, making it convenient and quick to use. To accommodate different patient conditions, a clamping spring 17 is provided on one side of the compression clamp 11 to secure the oxygen bag 10 to the bed rail. A handle groove 18 on the clamping spring 17 allows the patient to easily carry the oxygen bag during movement. 10. To ensure the convenience of the entire oxygen inhalation device, the oxygen bag 10 has two states through the combination of the clamping spring 17 and the handle groove 18: the clamping spring 17 is used to easily fix it to the bed rail, so that the oxygen bag 10 is clamped on the rail. When it is necessary to carry the oxygen bag 10 out, the handle groove 18 is held so that the patient or caregiver can easily carry the oxygen bag 10. The fixing method using the clamping spring 17 is not only simple in structure and low in cost, but also highly efficient. After the oxygen bag 10 is used up, it can be refilled with oxygen by an oxygen generator or oxygen station and reused. The oxygen bag 10 and the oxygen inhalation tube 1 are connected through the connector on the oxygen bag 10. The connector is located at the top of the oxygen bag 10 and is a flexible rubber joint to ensure that the oxygen inhalation tube 1 can be fully inserted into the interface and fit tightly to prevent oxygen leakage.

[0047] The workflow of the technical solution provided by this invention is as follows:

[0048] In use, first insert the output end of the oxygen cannula 1 into the patient's nasal cavity. The oxygen cannula 1 passes through the tube hole 5 at the bottom of one side of the fixing plate 4 into the patient's nasal cavity. The inner wall size of the tube hole 5 matches the outer wall size of the oxygen cannula 1, allowing the tube hole 5 to fix the position of the oxygen cannula 1. Then, by partially folding the fixing plate 4 between the upper and lower tube holes 5 on the same side, the oxygen cannula 1 is suspended in the nasal cavity. The thin design of the fixing plate 4 can prevent oxygen leakage and ensure the overall structure is lightweight. The support frame 6 is flexible. The curved, elastic structure adapts to the nasal contours of different patients, ensuring their comfort. After adjusting the oxygen tube 1 at the patient's nose, the ear hook 2 is placed on the patient's ear. The ear hook 2 is made of medical-grade silicone, which has good elasticity and flexibility. This characteristic allows the medical-grade silicone to conform well to the skin surface when in contact with the skin, reducing pressure on the skin. The overall curved contour of the ear hook 2 conforms to the auricle structure for better fit. Patients can adjust it according to their own ear size and shape to further improve wearing comfort.

[0049] After the oxygen tubing 1 is connected, open the speed control valve and adjust the oxygen flow rate to ensure normal oxygen output. By setting the ear hook 2, discomfort in the ear can be avoided when the patient wears it for too long. The curvature of the ear hook 2 can be bent freely. The bottom of the ear hook 2 has evenly distributed weakening grooves 3, which facilitates adjustment of the curvature and reduces the weight of the ear hook 2, making the structure lighter.

[0050] In addition, the ear loop 2 is directly attached to the oxygen tube 1. It can be easily disassembled or its height adjusted according to different patient postures. The bottom arc of the ear loop 2 makes it easy to adjust the tightness of the oxygen tube 1 between the nasal cavity and the ear loop 2. Then, one end of the oxygen bag 10 is inserted into the clamping slit 21 through the insertion slit 12. The protrusion 22 is used to clamp the oxygen bag 10. During the patient's oxygen inhalation, as the amount of oxygen inside the oxygen bag 10 decreases, the oxygen supply pressure of the oxygen bag 10 also decreases. By manually rotating the knob 19, the end of the oxygen bag 10 is rolled between the clamping tube 20 and the limiting spring 14, thereby adjusting the oxygen supply pressure inside the oxygen bag 10 and ensuring normal oxygen output. The distance between the insertion slits 12 is only greater than the thickness of the oxygen bag 10, which makes it easy to squeeze the oxygen as much as possible, ensuring oxygen utilization rate, and also making the oxygen bag 10 smaller in size after storage, making it easy to store and carry.

[0051] The compression clamp 11 and the limiting spring 14 are manufactured as a single unit. This design simplifies the manufacturing process, makes them easier to produce, and reduces the manufacturer's investment. To accommodate different patient conditions, a clamping spring 17 is provided on one side of the compression clamp 11 to facilitate fixing the oxygen bag 10 to the bed rail. A handle groove 18 on the clamping spring 17 allows the patient to easily carry the oxygen bag 10 during movement, ensuring the convenience of the entire oxygen inhalation device. Through the combination of the clamping spring 17 and the handle groove 18, the oxygen bag 10 can exist in two states: using the clamping spring 17 for easy attachment and dispensing. The bed rails are fixed so that the oxygen bag 10 is clamped to the rails. When the oxygen bag 10 needs to be carried outside, the handle groove 18 makes it easy for the patient or caregiver to hold the oxygen bag 10. The fixing method using the clamping spring 17 is not only simple and inexpensive, but also highly efficient. The portable oxygen inhalation device provided by this invention is suitable for patients' temporary or short-term oxygen inhalation needs. The flow regulating valve 8 on the oxygen inhalation tube 1 can be manually adjusted by adjusting the roller on the flow regulating valve 8 to adjust the oxygen flow rate. The humidifying filter 9 is set to increase the humidity of the oxygen and avoid dry oxygen from irritating the respiratory tract.

Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.
