Description

Technical Field

[0001] This invention relates to the field of oxygen supply equipment technology, and more specifically, to a portable integrated oxygen supply and nursing device for emergency care. Background Technology

[0002] In scenarios such as pre-hospital emergency care, in-hospital patient transfer, field emergency care, and public health emergencies, oxygen supply is a core emergency measure for respiratory support and vital sign maintenance in critically ill patients, directly determining the success rate of treatment and prognosis. The portable integrated oxygen supply and nursing device for emergency care combines multiple functions such as oxygen supply, parameter monitoring, auxiliary nursing, and portable power supply. It can adapt to the special operational needs of mobile emergency care and dynamic transport, effectively simplifying emergency operation procedures and shortening emergency response time. It solves the industry pain points of traditional split-type emergency equipment, such as poor adaptability, cumbersome operation, and low rescue efficiency, and is an indispensable core device in the modern mobile emergency care system.

[0003] Since this equipment is mainly used in dynamic scenarios such as ambulance transport, outdoor road movement, and on-site emergency rescue and transfer, the equipment is constantly under vibration, tilt, displacement, and external pressure in such scenarios. This can easily cause problems such as pressure fluctuations in the equipment's oxygen supply pipeline, deformation of the oxygen storage device under pressure, and deviation of the flow control valve. Ultimately, this leads to fluctuating oxygen supply flow and unbalanced oxygen supply accuracy, making it impossible to provide patients with a stable and compliant oxygen supply, thereby affecting the emergency treatment effect.

[0004] To address the common issues of fluctuating oxygen supply flow and insufficient oxygen pressure during transport under bumpy conditions, current methods primarily rely on fixed mechanical pressure stabilization structures paired with constant flow valves. These valves are controlled by fixed limit structures, and a simple buffer chamber is used to passively buffer oxygen pressure, thereby mitigating the impact of vibrations on the oxygen supply system. However, this simple buffer chamber only provides small-scale static pressure compensation and lacks dynamic pressure regulation capabilities. When the equipment experiences severe vibrations, tilting, or a decrease in gas supply capacity, the oxygen output pressure cannot be compensated in real time, easily leading to oxygen pressure attenuation and insufficient terminal pressure. This results in insufficient oxygen supply throughput, failing to meet the high-flow oxygen needs of critically ill patients.

[0005] In view of this, we propose a portable oxygen supply and nursing device for emergency care to improve the shortcomings of existing technologies. Summary of the Invention

[0006] This invention provides an integrated portable oxygen supply and nursing device for emergency care, which solves the problem that existing portable oxygen supply devices are prone to pipeline pressure fluctuations in bumpy transport scenarios, resulting in poor oxygen supply stability and difficulty in meeting the stable oxygen supply needs of critically ill patients.

[0007] To achieve the above objectives, the portable oxygen supply and nursing integrated device for emergency care includes a housing, a control panel for monitoring oxygen supply data is provided on one side of the housing, and a buffer cavity is provided inside the housing; An airbag is installed on the inner bottom wall of the buffer chamber. A compression plate is provided above the airbag in the buffer chamber. Several counterweight balls are provided on the top of the compression plate. When the shell is subjected to bumps, the counterweight balls slide back and forth on the top of the compression plate, so that the height of the two sides of the compression plate that are far apart changes, thereby squeezing the airbag to increase its oxygen supply.

[0008] In the above technical solution, the two outlets of the airbag are connected to an oxygen cylinder and an emergency mask, respectively. The oxygen cylinder supplies oxygen to the patient through the emergency mask. If a bumpy situation is encountered during the emergency, such as when the ambulance encounters potholes while transporting the patient, the oxygen flow from the oxygen cylinder to the patient may be reduced, which is not conducive to stabilizing the patient's condition.

[0009] Because the compression plate in this application has a pair of far-away sides that are not constrained, multiple counterweight balls will roll back and forth on the top of the compression plate. Under the action of the weight of the counterweight balls, wherever the counterweight balls roll to, the height of the edge of the compression plate on that side will be reduced by the pressure of the counterweight balls. The reduced height of the compression plate edge will compress the airbag, thereby increasing the amount of oxygen delivered to the patient.

[0010] Based on this, the airbag is connected to two air tubes, and the outside of the shell is provided with an air inlet and an air outlet, which are respectively connected to the corresponding air inlet and air outlet.

[0011] Both the air inlet and the air outlet are connected to the buffer chamber. The air inlet is used to connect to an external oxygen tank, and the air outlet is connected to an external emergency mask.

[0012] With this design, because the internal volume of the airbag is much larger than the volume of the ventilation tube and the external connecting pipes, the oxygen delivered from the oxygen cylinder, after entering the airbag through the inlet, first fills the internal space of the airbag before passing through the outlet to reach the emergency mask. Therefore, if a bumpy situation occurs during patient rescue, the oxygen inside the airbag will be accelerated and squeezed into the emergency mask by the back-and-forth squeezing plates on both sides, thereby increasing the oxygen supply to the emergency patient.

[0013] In another technical solution, rotating shafts are fixedly connected to both sides of the extrusion plate that are far apart, and the two rotating shafts are symmetrically arranged. The rotating shafts are adjacent to the two sides of the extrusion plate where the height can be changed.

[0014] Furthermore, in the horizontal direction, the relative position of the rotating shaft and the inner wall of the buffer cavity is fixed, while in the vertical direction, the relative position of the rotating shaft and the inner wall of the buffer cavity is adjustable. The top of the extrusion plate is provided with several rolling grooves, and each of the counterweight balls rolls and fits against the rolling groove.

[0015] In this technical solution, when the counterweight ball rolls left and right along the guide of the rolling groove on the top of the extrusion plate, and a pair of opposite sides of the extrusion plate are not constrained, the unconstrained sides of the extrusion plate will flip up and down under the action of the counterweight ball's gravity, thereby squeezing the airbag at the bottom of the extrusion plate, so as to increase the amount of oxygen delivered to the patient in bumpy road conditions where the oxygen supply is reduced.

[0016] Furthermore, the outer side of the rotating shaft is provided with a lifting block, the rotating shaft is rotatably connected to the lifting block, and a pair of opposite inner sidewalls of the buffer cavity are provided with lifting grooves, and each lifting block is slidably connected in the corresponding lifting groove.

[0017] Furthermore, the lifting block slides vertically within the lifting groove, and the lifting block has limit holes on both sides of the rotating shaft. A guide rod is fixedly connected within the lifting groove, and the limit holes are slidably connected to the guide rod.

[0018] The improvement is that a first spring is fitted on the outer side of the guide rod between the top of the lifting block and the inner top wall of the lifting groove or between the bottom of the lifting block and the inner bottom wall of the lifting groove.

[0019] As can be seen from the above scheme, when the shell is subjected to horizontal bumps, the counterweight ball slides back and forth in the rolling groove, and the two sides of the extrusion plate that are not constrained flip and move back and forth, thereby extruding the airbag.

[0020] As the counterweight ball bounces up and down, it remains within the rolling groove on the horizontal plane. Therefore, under its own weight, the counterweight ball drives the lifting block to slide up and down within the lifting groove via the compression plate, thus maintaining pressure on the airbag and increasing oxygen supply to the patient. During this process, all the first springs on the outer side of the guide rod undergo elastic deformation and store elastic potential energy. After the vehicle leaves the bumpy road section, the lifting block, under the restoring force of the multiple first springs, drives the counterweight ball back to its original position. This ensures that the oxygen supply remains stable throughout the entire emergency treatment, thereby maintaining the patient's condition.

[0021] Preferably, when the extrusion plate is in a horizontal state, the bottom of the extrusion plate is in contact with the top of the airbag.

[0022] The unconstrained sides of the extrusion plate are provided with protective plates. Several second springs are provided on the side of the protective plate away from the extrusion plate. The end of the second spring away from the protective plate is fixedly connected to the inner side wall of the buffer cavity.

[0023] With the above improvements, as the counterweight ball rolls back and forth on the top of the extrusion plate, when the counterweight ball slides to the lowest point, it contacts the protective plate. The kinetic energy and gravitational potential energy of the counterweight ball are converted into the elastic potential energy of the second spring, thereby protecting the control panel.

[0024] Based on the above description, the beneficial effects of the present invention compared with the prior art are as follows: 1. When the shell is subjected to horizontal bumps, the counterweight ball slides back and forth in the rolling groove, and the unconstrained sides of the compression plate flip and move back and forth, thereby compressing the airbag; when the counterweight ball bounces up and down, the counterweight ball is always located in the rolling groove on the horizontal plane. Therefore, under the action of the counterweight ball's gravity, the counterweight ball drives the lifting block to slide up and down in the lifting groove through the compression plate, thus still being able to compress the airbag to increase the oxygen supply to the patient.

[0025] 2. As the counterweight ball rolls back and forth on the top of the extrusion plate, when the counterweight ball slides to the lowest point, it contacts the protective plate. The kinetic energy and gravitational potential energy of the counterweight ball are converted into the elastic potential energy of the second spring, thereby protecting the control panel.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] To address the common issues of fluctuating oxygen supply flow and insufficient oxygen pressure during transport under bumpy conditions, current methods primarily rely on fixed mechanical pressure stabilization structures paired with constant flow valves. These valves are controlled by fixed limit structures, and a simple buffer chamber is used to passively buffer oxygen pressure, thereby mitigating the impact of vibrations on the oxygen supply system. However, this simple buffer chamber only provides small-scale static pressure compensation and lacks dynamic pressure regulation capabilities. When the equipment experiences severe vibrations, tilting, or a decrease in gas supply capacity, the oxygen output pressure cannot be compensated in real time, easily leading to oxygen pressure attenuation and insufficient terminal pressure. This results in insufficient oxygen supply throughput, failing to meet the high-flow oxygen needs of critically ill patients.

[0032] Please see Figure 1 - Figure 3To solve the above problems, the present invention aims to provide an integrated portable oxygen supply and nursing device for emergency care. The integrated device includes a housing 100, a control panel 101 for monitoring oxygen supply data is provided on one side of the housing 100, and a buffer cavity 102 is provided inside the housing 100. An airbag 110 is installed on the inner bottom wall of the buffer chamber 102. A compression plate 200 is provided above the airbag 110 in the buffer chamber 102. Several counterweight balls 210 are provided on the top of the compression plate 200. When the shell 100 is bumped, the counterweight balls 210 slide back and forth on the top of the compression plate 200, so that the height of the two sides of the compression plate 200 that are far apart changes, thereby compressing the airbag 110 to increase its oxygen supply.

[0033] During operation, the two outlets of the airbag 110 are connected to an oxygen cylinder and an emergency mask, respectively. The oxygen cylinder supplies oxygen to the patient through the emergency mask. If the emergency process encounters bumpy conditions, such as when the ambulance encounters potholes while transporting the patient, the oxygen flow from the oxygen cylinder to the patient may decrease, which could hinder the stabilization of the patient's condition.

[0034] Since the compression plate 200 in this application has a pair of far apart sides that are not constrained, multiple counterweight balls 210 will roll back and forth on the top of the compression plate 200. Under the action of the gravity of the counterweight balls 210, wherever the counterweight balls 210 roll to, the height of the edge of the compression plate 200 on that side will be reduced by the pressure of the counterweight balls 210. The edge of the compression plate 200 with reduced height will compress the airbag 110, thereby increasing the amount of oxygen delivered to the patient.

[0035] Next, as Figure 4 As shown, the airbag 110 is connected to the housing 100 and the external air pressure connection relationship. The airbag 110 is connected to two air tubes 111. The outside of the housing 100 is provided with an air inlet 103 and an air outlet 104, which are respectively connected to the air inlet 103 and the air outlet 104.

[0036] Both the air inlet 103 and the air outlet 104 are connected to the buffer chamber 102. The air inlet 103 is used to connect to an external oxygen tank, and the air outlet 104 is connected to an external emergency mask.

[0037] Because the internal volume of the airbag 110 is much larger than the internal volume of the ventilation tube 111 and the external connecting pipes, the oxygen delivered from the oxygen cylinder, after entering the airbag 110 through the inlet 103, will first fill the internal space of the airbag 110, and then pass through the outlet 104 to reach the emergency mask. Therefore, if a bumpy situation occurs during the emergency treatment of the patient, the oxygen inside the airbag 110 will be accelerated and squeezed into the emergency mask by the back-and-forth squeezing plates 200 on both sides, thereby increasing the oxygen supply to the emergency patient.

[0038] Based on the above, see [reference] Figure 5 - Figure 7The connection relationship between the extrusion plate 200 and the inner wall of the buffer cavity 102, the connection relationship between the counterweight ball 210 and the extrusion plate 200 and the bottom wall of the buffer cavity 102, and the preferred effects of such arrangement are disclosed. Two rotating shafts 201 are fixedly connected to the two opposite sides of the extrusion plate 200. The two rotating shafts 201 are symmetrically arranged and are adjacent to the two sides of the extrusion plate 200 where the height can be changed.

[0039] Furthermore, in the horizontal direction, the relative position of the rotating shaft 201 and the inner wall of the buffer cavity 102 is fixed, while in the vertical direction, the relative position of the rotating shaft 201 and the inner wall of the buffer cavity 102 is adjustable. Several rolling grooves 202 are provided on the top of the extrusion plate 200, and each counterweight ball 210 rolls and fits against the rolling groove 202.

[0040] When the counterweight ball 210 rolls left and right along the guide of the rolling groove 202 on the top of the compression plate 200, and the two opposite sides of the compression plate 200 are not restrained, the unrestrained sides of the compression plate 200 will flip up and down under the action of the gravity of the counterweight ball 210, thereby squeezing the airbag 110 at the bottom of the compression plate 200, so as to increase the amount of oxygen delivered to the patient in the bumpy road conditions where the oxygen supply is reduced.

[0041] Furthermore, a lifting block 220 is provided on the outer side of the rotating shaft 201. The rotating shaft 201 and the lifting block 220 are rotatably connected. A pair of opposite inner sidewalls of the buffer cavity 102 are provided with lifting grooves 230. Each lifting block 220 is slidably connected in the corresponding lifting groove 230.

[0042] Furthermore, the lifting block 220 slides in the lifting groove 230 in a vertical direction. The lifting block 220 has limit holes 221 on both sides of the rotating shaft 201. A guide rod 231 is fixedly connected in the lifting groove 230, and the limit holes 221 are slidably connected to the guide rod 231.

[0043] The improvement is that a first spring 232 is fitted on the outer side of the guide rod 231 between the top of the lifting block 220 and the inner top wall of the lifting groove 230 or between the bottom of the lifting block 220 and the inner bottom wall of the lifting groove 230.

[0044] It should be noted that when the housing 100 is subjected to a horizontal bump, the counterweight ball 210 slides back and forth in the rolling groove 202, and the unrestrained sides of the compression plate 200 flip and turn back and forth, thereby compressing the airbag 110.

[0045] Due to the complexity of real-world road conditions, the housing 100 in use will also experience vertical bumps during the transport of emergency patients by ambulance. When the counterweight ball 210 bounces up and down, it remains within the rolling groove 202 on the horizontal plane. Therefore, under the influence of its own weight, the counterweight ball 210 drives the lifting block 220 to slide up and down within the lifting groove 230 via the compression plate 200, thus still compressing the airbag 110 to increase oxygen supply to the patient. During this period, all the first springs 232 on the outer side of the guide rod 231 undergo elastic deformation and store elastic potential energy. After the vehicle leaves the bumpy road section, the lifting block 220, under the restoring force of the multiple first springs 232, drives the counterweight ball 210 back to its original position. This ensures that the oxygen supply remains stable throughout the entire emergency treatment process, thereby maintaining the patient's stable condition.

[0046] The control panel 101 for monitoring oxygen supply data integrates a number of electronic components. If the counterweight ball 210 directly impacts the inner wall of the buffer chamber 102 during its left and right rolling, it can easily damage the electronic components inside the control panel 101. In this application, the following improvement is made: when the extrusion plate 200 is in a horizontal state, the bottom of the extrusion plate 200 is in contact with the top of the airbag 110.

[0047] Preferably, protective plates 300 are provided on both sides of the unconstrained extrusion plate 200, and a plurality of second springs 310 are provided on the side of the protective plate 300 away from the extrusion plate 200. The end of the second spring 310 away from the protective plate 300 is fixedly connected to the inner wall of the buffer cavity 102.

[0048] In other words, as the counterweight ball 210 rolls back and forth on the top of the extrusion plate 200, when the counterweight ball 210 slides to the lowest point, it comes into contact with the protective plate 300. The kinetic energy and gravitational potential energy of the counterweight ball 210 are converted into the elastic potential energy of the second spring 310, thereby protecting the control panel 101.

[0049] The working principle of this integrated device will be explained in more detail below: An external oxygen cylinder fills the air bag 110 in the buffer chamber 102 with oxygen through the air inlet 103 and the air pipe 111. After the air bag 110 is filled with oxygen, it is delivered to the emergency mask through the air outlet 104 to provide oxygen to the patient. The control panel 101 monitors the oxygen supply-related data in real time.

[0050] When the housing 100 encounters horizontal bumps, the counterweight ball 210 rolls back and forth along the rolling groove 202 on the extrusion plate 200. Under the action of gravity, it drives the unconstrained side of the extrusion plate 200 to flip up and down, continuously extruding the airbag 110, supplementing the oxygen output and offsetting the decrease in flow caused by the bumps.

[0051] When the housing 100 is subjected to vertical bumps, the counterweight ball 210 drives the compression plate 200, the rotating shaft 201 and the lifting block 220 to slide vertically along the guide rod 231 in the lifting groove 230, simultaneously compressing the airbag 110; during the process, the first spring 232 undergoes elastic deformation to store potential energy. After the bumps disappear, the first spring 232 releases its elastic force, driving the lifting block 220, the compression plate 200 and the counterweight ball 210 to return to their original positions.

[0052] When the counterweight ball 210 rolls to its limit position, it touches the protective plate 300. The second spring 310 undergoes elastic deformation to absorb the impact force, preventing vibration transmission from damaging the internal components of the control panel 101.

[0053] In summary, through the aforementioned structural coordination, this integrated device dynamically adjusts oxygen output under various bumpy operating conditions, ensuring a continuous and stable oxygen supply flow.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
