Description

Technical Field

[0001] The invention relates to the technical field of oxygen supply equipment, and in particular to a portable oxygen inhalation device. Background Art

[0002] For patients with dyspnea or hypoxia, they need to carry an oxygen bag to replenish oxygen at any time during MRI examinations to relieve dyspnea and maintain normal blood oxygen levels. Oxygen bags are light and easy to carry, simple to operate, and suitable for temporary or short-term oxygen needs.

[0003] The conventional ordinary medical oxygen bag has the disadvantages in clinical use. When the oxygen tube is worn, the length of the nasal plug of the oxygen tube is fixed, which is inconvenient to adjust the length of the nasal plug entering the patient's nasal cavity, which easily leads to discomfort in the patient during wearing. Then, the oxygen tube is passed behind the patient's ear and the length is appropriately adjusted to fix the oxygen tube. If the oxygen tube is passed behind the ear for a long time and fixed, it may cause a sense of pressure on the patient's ear and may also affect the patient's head movement, making it inconvenient for the patient to turn over or move his head. In addition, the placement direction of the plastic strap on the oxygen tube, if the plastic strap is facing downward, may cause certain pressure on the patient's skin, especially for patients who breathe oxygen for a long time, which may easily cause redness or pressure injuries. If it is placed upward, the oxygen tube cannot be better fixed, and oxygen leakage is easy to occur. In addition, when the patient sits up, turns over, etc., the oxygen device is easily pulled, causing the oxygen tube to fall off. In addition, the pressure of the ordinary oxygen bag continues to drop during oxygen supply, and medical staff needs to press the oxygen bag. Manual pressing not only has uneven pressure but also is troublesome and laborious. Therefore, based on the above problems, the present invention provides a convenient oxygen inhalation device to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a portable oxygen inhalation device by arranging a supporting assembly and an extruding assembly. The supporting assembly and the extruding assembly are respectively arranged on the oxygen inhalation tube and the oxygen bag. The supporting assembly can not only improve the comfort of the patient wearing the oxygen inhalation tube, but also can ensure that the oxygen inhalation tube is not easy to fall off during the patient's activities, thereby avoiding the harm caused by the falling off of the oxygen inhalation tube; the extruding assembly can not only clamp and fix one end of the oxygen bag, but also can replace manual hand pressure to control the oxygen supply pressure, ensure the normal output of oxygen in the oxygen bag, and ensure the demand and quality of oxygen supply. Through the above arrangement, the problem of shortcomings of existing traditional ordinary medical oxygen bags in clinical use can be solved.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A portable oxygen inhalation device comprises an oxygen inhalation tube and an oxygen bag, wherein one end of the oxygen inhalation tube is fixedly connected with a support assembly, wherein the support assembly is used to assist the oxygen inhalation tube to prevent it from falling off during the oxygen inhalation process, and the support assembly is connected to the oxygen inhalation tube; and an extrusion assembly, wherein the extrusion assembly is used to ensure the normal output of oxygen in the oxygen bag, and the extrusion assembly is connected to the oxygen bag.

[0008] Optionally, the ear hook is a curved elastic structure, weakened grooves are evenly arranged at the bottom of the ear hook, and the inner wall size of the ear hook is consistent with the outer wall size of the oxygen absorption tube.

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

[0010] Optionally, the extrusion assembly includes a clamping tube clamped at one end of the oxygen bag, one end of the clamping tube is fixedly connected to a knob, the outer wall of the clamping tube is sleeved with a squeezing clamp, one end of the squeezing clamp is provided with two symmetrically upwardly bent flanges, the inner wall of the squeezing clamp is symmetrically fixedly connected to a limiting spring sheet, the other end of the squeezing clamp is fixedly connected to a clamping spring sheet, one side of the clamping spring sheet is provided with an opening, and a handle groove is provided through the clamping spring sheet.

[0011] Optionally, a clamping slit is formed on one side of the clamping tube, and raised portions are symmetrically provided at the bottoms of both sides of the clamping slit, and the spacing between the raised portions is smaller than the thickness of the end portion of the oxygen bag.

[0012] Optionally, the extrusion clamp, the limiting spring sheet and the clamping spring sheet are an integrated manufacturing structure, and the whole is a curved elastic structure, lightweight grooves are evenly opened on the limiting spring sheet, and the limiting spring sheet is a curved elastic structure.

[0013] Optionally, one end of the extrusion clamp where the flange portion is provided is provided with an insertion slit, and a gap between the insertion slits is greater than a thickness of an end portion of the oxygen bag.

[0014] Optionally, a flow regulating valve is sleeved on the oxygen absorption tube, a humidification filter element is fixedly connected to the oxygen absorption tube near the bottom, and the bottom of the humidification filter element is connected to the oxygen bag through the oxygen absorption tube.

[0015] Optionally, the curvature and size of the flange portion match the outer contour size of the humidification filter element.

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

[0017] In the above scheme, by arranging a support component and an extrusion component, the support component and the extrusion component are respectively arranged on the oxygen tube and the oxygen bag. The support component can not only improve the comfort of the patient wearing the oxygen tube, but also ensure that the oxygen tube is not easy to fall off during the patient's activities, thereby avoiding the harm caused by the falling off of the oxygen tube; the extrusion 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, thereby ensuring the normal output of oxygen in the oxygen bag and ensuring the demand and quality of oxygen supply.

[0018] By providing a support frame and a fixing plate, and utilizing an adjustment groove for easy bending, it is ensured that the support frame can fit the patient's nose, and the fixing plate can prevent oxygen leakage, so that the oxygen tube can be suspended into the nasal cavity, and the length of the oxygen tube suspended into the nasal cavity can be adjusted arbitrarily, which greatly reduces the irritation to the nasal mucosa, allows the patient to inhale oxygen more comfortably, and greatly improves the patient's comfort level in oxygen inhalation.

[0019] By setting up the ear hook, the patient can avoid ear discomfort when wearing it for too long. The curvature of the ear hook can be bent freely, and the bottom of the ear hook is provided with evenly distributed weakening grooves, which is convenient for adjusting the curvature while also reducing the weight of the ear hook, making the structure lighter. In addition, the ear hook is directly mounted on the oxygen tube, and can be easily removed or adjusted in height up and down according to the patient's different postures. The curvature setting at the bottom of the ear hook makes it convenient to adjust the oxygen tube between the nasal opening and the ear hook to the appropriate tightness.

[0020] By arranging the extrusion clamp, the clamping tube and the limiting spring piece, the oxygen bag is clamped by the clamping tube, and the knob is manually rotated and the extrusion clamp and the limiting spring piece cooperate to make the oxygen bag be rolled into the extrusion clamp 11 in sequence, so as to control the oxygen supply pressure of the oxygen bag. Not only is the structure simple and ingenious, but also the actual operation is convenient and labor-saving. In addition, the extrusion clamp and the limiting spring piece are an integrated manufacturing structure. Such an arrangement makes the processing technology of the three simpler during the production process, and makes it easier to be produced and manufactured, thereby reducing the capital investment of the manufacturer.

[0021] By arranging the clamping spring piece and the handle groove, the oxygen bag exists in two states: the clamping spring piece is used to conveniently fix the oxygen bag to the guardrail of the hospital bed, so that the oxygen bag is clamped on the guardrail. When the oxygen bag needs to be carried outside, the patient or the accompanying personnel can hold the handle groove to carry the oxygen bag, which is convenient for carrying; the fixing method using the clamping spring piece is not only simple in structure and low in cost, but also highly efficient.

[0040] like Figures 1 to 9As shown, an embodiment of the present invention provides a portable 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 assembly, the support assembly is used to assist the oxygen inhalation tube 1 to prevent it from falling off during the oxygen inhalation process; an extrusion assembly, the extrusion assembly is used to ensure the normal output of oxygen in the oxygen bag 10, the extrusion assembly is connected to the oxygen bag 10, a flow regulating valve 8 is sleeved on the oxygen inhalation tube 1, a humidification filter element 9 is fixedly connected to the oxygen inhalation tube 1 near the bottom, and the bottom of the humidification filter element 9 is connected to the oxygen bag 10 through the oxygen inhalation tube 1.

[0041] The portable oxygen inhalation device provided by the present invention is suitable for patients' temporary or short-term oxygen inhalation needs. The oxygen inhalation tube 1 runs through the extrusion disc and the extrusion plate of the flow regulating valve 8. When using the flow regulating valve, first rotate the adjustment knob counterclockwise to adjust the distance between the extrusion disc and the extrusion plate to the maximum. At this time, the distance between the extrusion disc and the extrusion plate is just the outer diameter length of an oxygen inhalation tube 1; push the oxygen inhalation tube 1 toward the anti-drop hook to compress the anti-drop pin, so that the anti-drop pin falls over, and the oxygen inhalation tube 1 smoothly enters between the extrusion disc and the extrusion plate; this At this time, the oxygen tube 1 has no compression effect on the release hook, so the anti-drop pin is reset under the action of the reset spring to limit the position of the oxygen tube 1; then you can start to turn the adjustment knob clockwise, the distance between the extrusion disc and the extrusion plate gradually becomes smaller, the oxygen tube 1 stuck between the extrusion plate and the extrusion disc is gradually squeezed, and the cross-sectional area becomes smaller, thereby realizing the adjustment of the oxygen bag flow rate. The squeezing degree of the oxygen tube 1 by the flow regulating valve can be arbitrarily controlled from 0% to 100%; the flow regulating valve 8 is provided with a threaded self-locking, which can stably control, The degree of compression on the oxygen tube 1 will not be affected by excessive air pressure. The working principle of the flow regulating valve 8 on the oxygen tube 1 is disclosed as a prior art, so no further elaboration is made. By setting a humidifying filter element 9 to increase the humidity of oxygen, dry oxygen is prevented from irritating the respiratory tract. The multi-layer structure and pleated design inside the humidifying filter element 9 increase the contact area between water and air, making it easier for water molecules to evaporate when passing through the filter element to form humidified oxygen. The working principle of the humidifying filter element 9 on the oxygen tube 1 is disclosed as a prior art, so no further elaboration is made. By setting a supporting component and an extruding component, the supporting component and the extruding component are respectively arranged on the oxygen tube 1 and the oxygen bag 10. The supporting component can not only improve the comfort of the patient wearing the oxygen tube 1, but also ensure that the oxygen tube 1 is not easy to fall off during the patient's activities, thereby avoiding the harm caused by the falling off of the oxygen tube 1; the extruding 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, ensure the normal output of oxygen in the oxygen bag 10, and ensure the demand and quality of oxygen supply.

[0042] like Figures 1 to 5As shown, the support assembly includes an ear hook 2 symmetrically sleeved on the oxygen inhalation tube 1, both ends of the oxygen inhalation tube 1 are inserted into the nasal cavity through a fixing plate 4, and tube holes 5 are symmetrically opened on the fixing plate 4. A support frame 6 is fixedly installed on one side of the fixing plate 4, and the support frame 6 is an elastic structure. Adjustment grooves 7 are evenly opened on the support frame 6. The ear hook 2 is a curved elastic structure, and weakening grooves 3 are evenly opened on the bottom of the ear hook 2. The inner wall size of the ear hook 2 is consistent with the outer wall size of the oxygen inhalation tube 1. Local folds are symmetrically provided at both ends of the bottom of the fixing plate 4, and tube holes 5 are provided on the local folds. The tube holes 5 on the local folds on the same side are correspondingly adapted to the tube holes 5 on the fixing plate 4. The bottom of the center of the fixing plate 4 has an arc-shaped structure concave toward the middle of the fixing plate 4. The ear hook 2 is made of medical silicone as a whole, and has good elasticity and flexibility. The ear hook 2 is preferably provided with a sling shaped ear hook 2, so that the patient can wear the ear hook 2 in a comfortable manner and the ear canal can be easily adjusted to the desired shape and size.

[0043] Among them, the tube holes 5 symmetrically opened on the fixing plate 4, the oxygen inhalation tube 1 respectively passes through the tube holes 5 at the bottom of one side of the fixing plate 4 to penetrate into the patient's nasal cavity, the inner wall size of the tube hole 5 is consistent with the outer wall size of the oxygen inhalation tube 1, so that the tube hole 5 can fix the position of the oxygen inhalation tube 1, and then the position of the oxygen inhalation tube 1 between the upper and lower tube holes 5 on the same side of the fixing plate 4 and the local fold is used to realize the length of the oxygen inhalation tube 1 suspended into the nasal cavity. The thin sheet design of the fixing plate 4 can prevent oxygen leakage and ensure the lightness of the overall structure. The support frame 6 is a freely bendable elastic structure as a whole, which is convenient for adapting to the nose contours of different patients and ensuring the comfort of the patient's wearing. By setting the support frame 6 and the fixing plate 4, the adjustment groove 7 is used to facilitate bending, ensuring that the support frame 6 can fit the patient's nose, and the fixing plate 4 can prevent oxygen leakage, so that the oxygen inhalation tube 1 can be suspended into the nasal cavity, and the length of the oxygen inhalation tube 1 suspended into the nasal cavity can be arbitrarily adjusted, which greatly reduces the stimulation to the nasal mucosa, allows the patient to breathe oxygen more comfortably, and greatly improves the comfort of the patient's oxygen inhalation.

[0044] like Figures 6 to 9As shown, the extrusion assembly includes a clamping tube 20 clamped at one end of the oxygen bag 10, one end of the clamping tube 20 is fixedly connected to a knob 19, the outer wall of the clamping tube 20 is sleeved with an extrusion clamp 11, one end of the extrusion clamp 11 is provided with two symmetrically upwardly bent flanges 13, the inner wall of the extrusion clamp 11 is symmetrically fixedly connected to a limiting spring sheet 14, the other end of the extrusion clamp 11 is fixedly connected to a clamping spring sheet 17, one side of the clamping spring sheet 17 is provided with an opening 16, the clamping spring sheet 17 is penetrated by a handle groove 18, one side of the clamping tube 20 is provided with a clamping seam 21, the bottoms of the two sides of the clamping seam 21 are symmetrically provided with protrusions 22, and the space between the protrusions 22 is symmetrical. The distance is less than the end thickness of the oxygen bag 10, the extrusion clamp 11, the limiting spring piece 14 and the clamping spring piece 17 are an integrated manufacturing structure, and the whole is a curved elastic structure. Lightweight grooves 15 are evenly opened on the limiting spring piece 14, and the limiting spring piece 14 is a curved elastic structure. An insertion seam 12 is opened at one end of the extrusion clamp 11 where the flange portion 13 is provided, that is, an insertion seam 12 is formed between the two flange portions 13, and the gap between the insertion seams 12 is greater than the end thickness of the oxygen bag 10, the curvature and size of the flange portion 13 are consistent with the outer contour size of the humidification filter element 9, and the clamping tube 20 is placed inside the extrusion clamp 11 and the position of the insertion seam 12 corresponds to the position of the clamping seam 21.

[0045] Specifically, one end of the oxygen bag 10 is inserted into the clamping slit 21 through the insertion slit 12, and the oxygen bag 10 is clamped by the protrusion 22. During the patient's oxygen inhalation process, 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 rolled between the clamping tube 20 and the limiting spring sheet 14, thereby adjusting the oxygen supply pressure in the oxygen bag 10 to ensure the normal output of oxygen. Due to the elastic structure of the limiting spring sheet 14, the limiting spring sheet 14 can produce elastic deformation under the extrusion of the oxygen bag 10 under the elastic action, and can use its own elasticity to produce secondary extrusion on the oxygen bag 10, which is convenient for fixing the position of the oxygen bag 10. The spacing between the insertion slits 12 is only greater than The thickness of the oxygen bag 10 is convenient for squeezing the oxygen as fully as possible, ensuring the oxygen utilization rate while making the volume of the oxygen bag 10 smaller after storage, which is convenient for storage and carrying. By setting the squeezing clamp 11, the clamping tube 20 and the limiting spring piece 14, the oxygen bag 10 is clamped by the clamping tube 20, and the knob 19 is manually rotated and the squeezing clamp 11 and the limiting spring piece 14 cooperate to make the oxygen bag 10 rolled into the squeezing clamp 11 in turn, thereby controlling the oxygen supply pressure of the oxygen bag 10. Not only is the structure simple and ingenious, but also the actual operation is convenient and labor-saving. In addition, the squeezing clamp 11 and the limiting spring piece 14 are an integrated manufacturing structure. Such a setting makes the processing technology of the three simpler during the production process, easier to be produced, and reduces the manufacturer's capital investment.

[0046] Among them, the p oxygen inhalation tube 1 is fixedly connected with a humidifying filter element 9 near the bottom, and the bottom of the humidifying filter element 9 is connected with the oxygen bag 10 through the oxygen inhalation tube 1. Since one end of the squeezing clamp 11 is provided with two symmetrically upwardly bent flanges 13, the humidifying filter element 9 is clamped on the flanges 13, and the outer contour curvature of the humidifying filter element 9 is adapted to the curvature of the flanges 13. The structural design of the flanges 13 on the squeezing clamp 11 is used to facilitate the clamping and fixing of the humidifying filter element 9, and due to the curved elastic structure of the flanges 13, the humidifying filter element 9 is convenient to disassemble and replace, and is convenient and quick to use. In order to adapt to the different conditions of the patient, a clamping spring 17 is provided on one side of the squeezing clamp 11 to facilitate fixing the oxygen bag 10 on the guardrail of the bed, and a handle groove 18 is provided on the clamping spring 17 to facilitate the patient to carry the oxygen bag when moving. 10, to ensure the convenience of the entire oxygen inhalation device, by setting the clamping spring piece 17 and the handle groove 18, the oxygen bag 10 has two states: the clamping spring piece 17 is used to facilitate the fixation with the guardrail of the bed, so that the oxygen bag 10 is clamped on the guardrail, and when the oxygen bag 10 needs to be carried out, the handle groove 18 is held by the patient or the accompanying personnel to carry the oxygen bag 10, which is convenient for carrying; the fixing method using the clamping spring piece 17 is not only simple in structure and low in cost, but also high in efficiency. After use, the oxygen bag 10 can be filled with oxygen by an oxygen concentrator or an oxygen station and reused; the oxygen bag 10 and the oxygen inhalation tube 1 are connected through the connecting port on the oxygen bag 10, and the connecting port is located at the top of the oxygen bag 10, which is a soft rubber joint, ensuring that the oxygen inhalation tube 1 can be fully inserted into the interface and fit tightly with it to prevent oxygen leakage.

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

[0048] When in use, first wear the output end of the oxygen tube 1 into the patient's nasal cavity, and the oxygen tube 1 passes through the tube holes 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 tube 1, so that the tube hole 5 can fix the position of the oxygen tube 1, and then use the position of the oxygen tube 1 between the upper and lower tube holes 5 on the same side of the fixing plate 4 to realize the length of the oxygen tube 1 suspended into the nasal cavity. The thin sheet design of the fixing plate 4 can prevent oxygen leakage and ensure the lightness of the overall structure. The support frame 6 is freely bendable as a whole. The curved elastic structure is convenient for adapting to the nose contours of different patients to ensure the comfort of the patient. After adjusting the oxygen tube 1 at the patient's nose, the ear hook 2 is worn on the patient's ear. The ear hook 2 is made of medical silicone as a whole and has good elasticity and flexibility. This characteristic enables the medical silicone to better fit the skin surface when in contact with the skin, reducing the sense of pressure on the skin. The overall arc contour of the ear hook 2 fits the auricle structure to achieve a better fit. The patient can adjust it according to the size and shape of his or her ears to further improve the wearing comfort.

[0049] After the oxygen tube 1 is connected, open the speed regulating valve and adjust the oxygen flow rate so that oxygen can be output normally. By providing the ear hook 2, it is prevented that the patient's ears will not feel uncomfortable when wearing it for too long. The curvature of the ear hook 2 can be bent freely, and the bottom of the ear hook 2 is provided with evenly distributed weakening grooves 3, which is convenient for adjusting the curvature and can also reduce the weight of the ear hook 2, making the structure lighter.

[0050] In addition, the ear hook 2 is directly sleeved on the oxygen inhalation tube 1, and can be conveniently disassembled or adjusted in height up and down according to the different postures of the patient. The curvature of the bottom of the ear hook 2 is set to facilitate the oxygen inhalation tube 1 between the nasal cavity and the ear hook 2 to be adjusted to a suitable tightness. Then, one end of the oxygen bag 10 is inserted into the clamping slit 21 through the insertion slit 12, and the oxygen bag 10 is clamped by the protrusion 22. During the patient's oxygen inhalation process, 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 rolled between the clamping tube 20 and the limiting spring sheet 14, thereby adjusting the oxygen supply pressure in the oxygen bag 10 to ensure the normal output of oxygen. The spacing between the insertion slits 12 is only greater than the thickness of the oxygen bag 10, which is convenient for squeezing the oxygen as fully as possible, ensuring the oxygen utilization rate, and also making the volume of the oxygen bag 10 smaller after storage, which is convenient for storage and carrying.

[0051] The extrusion clamp 11 and the limiting spring sheet 14 are an integrated manufacturing structure. Such a setting makes the processing technology of the three simpler during the production process, easier to be manufactured, and reduces the capital investment of the manufacturer. In order to adapt to the different states of the patient, a clamping spring sheet 17 is provided on one side of the extrusion clamp 11, so as to facilitate the fixing of the oxygen bag 10 on the guardrail of the bed. The handle groove 18 provided on the clamping spring sheet 17 facilitates the patient to carry the oxygen bag 10 during activities, thereby ensuring the convenience of the entire oxygen inhalation device. By providing the clamping spring sheet 17 and the handle groove 18, the oxygen bag 10 has two states: the clamping spring sheet 17 is convenient for the patient to carry the oxygen bag 10 with the patient, and the oxygen bag 10 is convenient for the patient to carry the oxygen bag 10 with the patient. The guardrail of the hospital bed is fixed so that the oxygen bag 10 is clamped on the guardrail. When the oxygen bag 10 needs to be carried out, the patient or the accompanying personnel can hold the handle groove 18 to carry the oxygen bag 10 for easy carrying; the fixing method using the clamping spring piece 17 is not only simple in structure and low in cost, but also highly efficient. The portable oxygen inhalation device provided by the present invention is suitable for the patient's temporary or short-term oxygen inhalation needs. The flow regulating valve 8 provided on the oxygen inhalation tube 1 can adjust the oxygen flow by manually adjusting the roller on the flow regulating valve 8. The humidifying filter element 9 is provided to increase the humidity of the oxygen to avoid dry oxygen from irritating the respiratory tract.

[0052] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
