Description

Technical Field

[0001] The present invention relates to the technical field of medical nursing equipment, and in particular to an oxygen diffusion module and a portable pressure-adjustable oxygen inhalation device. Background Art

[0002] After undergoing thoracic surgery, patients are relatively weak and affected by anesthetics, and their autonomous breathing ability is poor. Especially in cases such as lung resection and esophageal surgery, patients' respiratory function will be limited due to reduced lung tissue, impaired respiratory muscle function or postoperative pain, which can easily lead to hypoxemia. Therefore, continuous oxygen supply is required for patients after thoracic surgery to ensure sufficient oxygen content in the body. In addition, patients with respiratory diseases who need rehabilitation exercises also need to use oxygen inhalation devices for oxygen supply.

[0003] Currently, the commonly used oxygen inhalation devices in clinical practice are nasal cannulas or oxygen masks. Nasal cannulas are a nasal oxygen supply method that is easy to operate, low in cost, and can deliver oxygen directly to the nasal cavity, providing a high degree of freedom of movement without affecting the patient's eating and speaking; oxygen masks are a diffuse oxygen supply method that can provide a higher oxygen concentration and facilitate humidification of oxygen. Both can provide basic oxygen supply to patients.

[0004] In the prior art, a public document with publication number CN213554649U discloses a new type of respiratory mask for thoracic surgery nursing. The respiratory mask includes a working barrel and a mask. The mask is worn on the patient's head through an elastic band. A spiral tube is provided in the working barrel. One end of the spiral tube is connected to the oxygen valve, and the other end is connected to the respiratory mask through a hose to transport oxygen into the respiratory mask. However, the respiratory mask still has the following problems during use: (1) For patients who are bedridden after surgery but cannot move, the mask cannot adjust the patient's body position. The patient maintains a certain posture for a long time, which is not conducive to the patient's autonomous breathing recovery; (2) For patients who have recovered a certain degree of autonomous breathing ability and need to get out of bed and walk for exercise, medical staff or family members need to carry the working barrel to move, which is poor in portability; (3) Patients at different stages have different requirements for oxygen inhalation, and the mask cannot autonomously adjust the oxygen supply. Summary of the Invention

[0005] To address the above-mentioned problems, the present invention aims to provide an oxygen diffusion module that allows the patient to autonomously adjust the oxygen supply according to their stage of recovery to meet different oxygen inhalation needs. Furthermore, the present invention aims to provide a portable, pressure-adjustable oxygen inhalation device. For patients in the bedridden recuperation stage, the device can adjust the patient's body position and achieve oxygen supply. For patients in the ambulation exercise stage, the device can be worn directly by the patient without the need for medical staff or family members to carry it. By using the above-mentioned oxygen diffusion module, the device is portable and can meet the different oxygen supply needs of patients at different stages.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the oxygen diffusion module of the present invention is as follows: An oxygen diffusion module includes a hollow shell, the hollow shell is used to be connected to an oxygen supply device, a porous plate is installed on the hollow shell, and the porous plate has multiple oxygen diffusion holes for oxygen diffusion, and further includes: A partition plate, movably mounted in the hollow shell; The compression reset body is distributed at the four corners of the partition plate, one end of which is connected to the hollow shell and the other end is connected to the partition plate; The diffusion amount adjusting member is connected to the partition plate through a connecting rod, is located between the porous plate and the partition plate, and is plugged into and matched with the oxygen diffusion hole to form an oxygen diffusion hole with an adjustable aperture; A plurality of metal balls are located between the diffusion volume adjusting member and the partition plate and roll randomly, so as to change the pressure distribution on the compression reset body.

[0007] Through this solution, the position of the metal balls changes the pressure distribution on the partition plate, causing the compression reset bodies at the four corners of the partition plate to deform differently. These different deformations of the compression reset bodies cause the partition plate to tilt, resulting in a certain displacement. This, in turn, drives the diffusion adjuster via a connecting rod to produce the same tilting displacement, increasing or decreasing the insertion depth between the diffusion adjuster and some of the oxygen diffusion holes, thereby regulating the oxygen flow through the oxygen diffusion holes. During use, the patient can manually flip the hollow shell to change the distribution of the metal balls, thereby autonomously adjusting the oxygen flow.

[0008] Furthermore, the diffusion adjustment element includes: a base plate connected to the connecting rod; The pillars are evenly distributed on the substrate, extending toward the porous plate and corresponding to the oxygen diffusion holes one by one; The tapered plug is connected to the upper end of the support and the small diameter end of the tapered plug is inserted into the oxygen diffusion hole.

[0009] With the above solution, when the partition plate is tilted, the base plate is also tilted accordingly, and the conical plug is driven to be tilted by the support, so that the insertion depth between the conical plug and the corresponding oxygen diffusion hole increases or decreases, thereby realizing the regulation of oxygen flow.

[0010] Furthermore, a conductor is connected between the partition plate and the hollow shell, and the conductor is used to generate a magnetic field so that the metal balls are evenly distributed on the partition plate.

[0011] Through the above scheme, the conductor is energized, so that the metal balls are evenly distributed on the partition plate under the action of the magnetic field. At this time, the compression reset bodies at the four corners of the partition plate are subjected to the same pressure, and the insertion depth between the conical plug and the oxygen diffusion hole is the shallowest, which is the maximum oxygen supply state.

[0012] The beneficial effects of the present invention are as follows: compared with the prior art, the improvement of the present invention is that: By changing the distribution of the metal balls, the pressure distribution on the partition plate can be altered, which in turn changes the deformation of the compression reset bodies at the four corners of the partition plate, causing the partition plate to tilt. This, in turn, drives the diffuser plate and conical plug to tilt accordingly via a connecting rod, thereby increasing or decreasing the insertion depth between the conical plug and the corresponding oxygen diffusion hole, thereby adjusting the oxygen flow rate. During use, the patient can manually flip the hollow shell to change the distribution of the metal balls, thereby achieving autonomous oxygen flow regulation. This is suitable for patients with good independent breathing ability.

[0013] 2. By energizing the conductor, the metal balls can be evenly distributed on the partition plate under the action of the magnetic field. At this time, the compression reset bodies at the four corners of the partition plate are subjected to the same pressure, and the insertion depth between the conical plug and the oxygen diffusion hole remains the same. The insertion depth is the shallowest, which is the maximum oxygen supply state. It is suitable for patients who have just undergone surgery and have poor autonomous breathing ability.

[0014] The technical solution adopted by the portable pressure-adjustable oxygen inhalation device of the present invention is as follows: A portable pressure-adjustable oxygen inhalation device comprises the above-mentioned oxygen diffusion module.

[0015] The portable adjustable pressure oxygen inhalation device also includes: A wearable body, wherein an oxygen supply and humidification system is provided, and the wearable body is connected to a neck fixing belt and a waist fixing belt for the patient to wear; an air pump connected to the wearable body; The cervical pillow airbag is connected to the wearable body and is connected to the air pump to be inflated and deformed, and is used to support the patient's neck to adjust the angle between the patient and the bed; The angle adjustment member is located in the cavity of the wearable body, and the cavity is connected to the air pump for inflation to achieve the flip adjustment of the angle of the angle adjustment member itself; The oxygen supply pipe is connected to the oxygen diffusion module and the angle adjustment member, and rotates with the angle adjustment member and drives the oxygen diffusion module to rotate.

[0016] Through the above scheme, the air pump inflates the neck pillow airbag and the cavity in the wearable body respectively, which can cause the neck pillow airbag to be inflated and deformed, and the angle adjustment part in the cavity to flip itself. The neck pillow airbag supports the patient's head and neck, and adjusts the angle between the patient's head and the bed, which is beneficial to the patient's respiratory recovery. The flipping of the angle adjustment part itself can drive the flipping of the oxygen supply tube and the oxygen diffusion module. The flipping of the oxygen diffusion module will change the distribution of the metal balls, thereby realizing the regulation of the oxygen flow.

[0017] Furthermore, the angle adjustment member includes: a pneumatic plate, slidably connected to the inner wall of the cavity of the wearable body; a sleeve, connected to the center of the pneumatic plate and moving horizontally with the pneumatic plate; A toothed shaft, one end of which is rotatably connected to the inside of the sleeve and the other end of which is provided with active helical teeth; The toothed transmission rod is respectively connected with the toothed rotating shaft and the oxygen supply tube; The stretching reset piece is connected to both ends of the pneumatic plate and is used to reset the pneumatic plate when the air pump stops inflating.

[0018] Through the above scheme, when the air pump inflates the cavity of the wearable body, the pneumatic plate moves horizontally under the action of air pressure, the stretching and resetting part is stretched and generates a restoring force, and the sleeve moves horizontally accordingly. The toothed shaft rotatably connected to the sleeve will output the horizontal movement as rotation, and drive the toothed transmission rod to rotate, thereby realizing the flip adjustment of the angle of the angle adjustment part itself. If the inflation is stopped, the pneumatic plate will be reset under the action of the restoring force of the stretching and resetting part, and the angle adjustment part will also be reset to the initial angle.

[0019] Furthermore, the toothed transmission rod comprises: A transmission shaft is arranged perpendicular to the toothed shaft; The driven helical gear is sleeved on the middle part of the transmission shaft and meshes with the driving helical gear; The end gears are sleeved on both ends of the transmission shaft and mesh with the oxygen supply tube.

[0020] Through the above scheme, when the toothed shaft rotates and drives the active helical teeth to rotate, the driven helical teeth meshing with the active helical teeth also rotate, thereby driving the transmission shaft to rotate synchronously. At this time, the end gears at both ends of the transmission shaft also rotate and drive the oxygen supply tube matched with it to rotate, thereby realizing the angle adjustment of the oxygen diffusion module.

[0021] Furthermore, the oxygen supply tube includes: an air pipe connected to the hollow shell of the oxygen diffusion module; The toothed connecting end is a hollow ring structure, one end of which is connected to the trachea and the other end is connected to the oxygen supply and humidification system. The outer side of the toothed connecting end is provided with a matching gear that meshes with the end gear.

[0022] Through the above solution, when the end gear on the transmission shaft rotates, the matching gear meshing with the end gear will drive the toothed connecting end to rotate, thereby realizing the rotation of the oxygen supply tube.

[0023] Furthermore, the portable adjustable pressure oxygen inhalation device also includes: A control module connected to the wearable body; The chest pressure airbag is an arc-shaped structure connected to both sides of the wearable body. After inflation, it fits closely to the patient's chest contour. A pressure sensor is installed inside the chest pressure airbag to monitor the patient's chest pressure fluctuations. The back patting module is connected to the wearable body and is used to pat the patient's back to relieve phlegm accumulation in the lungs.

[0024] Through the above scheme, when the patient is lying in bed and breathing oxygen, the chest rises and falls less, and when the patient is walking and breathing oxygen, the chest rises and falls more. The pressure sensor can monitor the patient's chest rise and fall, thereby judging the patient's breathing status. The control module can receive the electrical signal of the pressure sensor to control the start-up of the back patting module to assist the patient's breathing.

[0025] Furthermore, the control module includes: An alarm is electrically connected to the pressure sensor, and when the chest cavity pressure is lower than a minimum pressure value, the alarm sounds an alarm; The motor is electrically connected to the back patting module and the pressure sensor. When the chest cavity pressure is higher than the maximum pressure value, the motor controls the back patting module to work.

[0026] Through the above scheme, the pressure sensor can monitor the patient's chest pressure. If the chest pressure is lower than the set minimum pressure value, the control module will control the alarm to sound an alarm to remind medical staff to pay attention to the patient's condition; if the chest pressure is higher than the set maximum pressure value, the control module will control the motor to start, driving the back patting module to pat the patient's back to relieve the patient's chest pressure.

[0027] The beneficial effects of the present invention are as follows: compared with the prior art, the improvement of the present invention is that: 1. Patients can wear the portable adjustable pressure oxygen inhalation device through the neck strap and waist strap, which makes it easy for patients to carry it independently during walking exercises without the need for family members or medical staff to accompany them, thereby improving the portability of the device.

[0028] 2. By inflating the cervical pillow airbag through an air pump, the angle between the patient's head and the bed can be adjusted. The cervical pillow airbag can provide support for the patient's head and neck, which is beneficial to the patient's respiratory recovery.

[0029] 3. The air pump is used to inflate the cavity of the wearable body, causing the pneumatic plate to move horizontally under the action of air pressure. The sleeve then moves horizontally, and the toothed shaft connected to the sleeve rotates, driving the toothed transmission rod to rotate, thereby realizing the flip adjustment of the angle adjustment part itself. The angle adjustment part drives the oxygen supply tube to rotate, and the oxygen supply tube drives the oxygen diffusion module to rotate, thereby changing the distribution of the metal balls and realizing the adjustment of the oxygen flow by the oxygen diffusion module.

[0030] 4. The pressure sensor can be used to monitor the patient's chest pressure. When the patient is lying in bed and inhaling oxygen, the chest fluctuates slightly, which makes it easy for oxygen poisoning to occur. If the chest pressure is lower than the set minimum pressure value, the control module will control the alarm to sound an alarm, reminding medical staff to pay attention to the patient's condition and avoid oxygen poisoning. If the patient rests in bed for a long time, it is easy for sputum to accumulate in the lungs. When the patient is walking and inhaling oxygen, the chest fluctuates greatly. If the chest pressure is higher than the set maximum pressure value, the control module will control the motor to start forward and reverse rotation, driving the back patting module to pat the patient's back to promote sputum discharge, relieve the patient's chest pressure, and reduce sputum accumulation.

DETAILED DESCRIPTION

[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0046] Example 1: Refer to the attached Figure 1-5 As shown, embodiment 1 provides an oxygen diffusion module, which specifically includes a hollow shell 1. A porous plate 101 is installed on the hollow shell 1. The porous plate 101 has multiple oxygen diffusion holes 1011 for oxygen diffusion. The hollow shell 1 is used to be connected to an oxygen supply device. The oxygen output by the oxygen device will enter the hollow shell 1 and diffuse from the oxygen diffusion holes 1011 of the porous plate 101 for inhalation by the patient.

[0047] Refer to the attached Figure 5 As shown, a partition plate 102 is movably installed in the hollow shell 1, and the partition plate 102 divides the hollow shell 1 into two parts. The part between the partition plate 102 and the hollow shell 1 is connected with a compression reset body 103, and the compression reset body 103 is distributed at the four corners of the partition plate 102. When the compression reset body 103 is deformed, it will drive the four corners of the partition plate 102 to tilt and displace. A diffusion volume adjustment member 104 is connected between the partition plate 102 and the porous plate 101 through a connecting rod 105. The diffusion volume adjustment member 104 is plugged into the oxygen diffusion holes 1011 on the porous plate 101 to form oxygen diffusion holes 1011 with adjustable apertures. A plurality of metal balls 106 are arranged in the area between the partition plate 102 and the diffusion volume adjustment member 104. The metal balls 106 roll arbitrarily between the partition plate 102 and the diffusion volume adjustment member 104, and the gathering position of the metal balls 106 changes. , the pressure distribution on the compression reset body 103 changes, thereby causing the deformation of the compression reset body 103 at the four corners of the partition plate 102 to be different. The different deformation of the compression reset body 103 will cause the partition plate 102 to tilt, resulting in a tilt displacement; when the partition plate 102 is tilted, it will drive the diffusion capacity adjustment member 104 to produce a corresponding tilt displacement, thereby changing the insertion depth of the diffusion capacity adjustment member 104 and the oxygen diffusion hole 1011 to achieve oxygen flow control of the oxygen diffusion hole 1011. Such a setting can improve the practicality of the oxygen diffusion module, reduce oxygen waste by controlling the oxygen diffusion capacity, and meet the different oxygen inhalation needs of patients in various rehabilitation stages. During specific use, the patient can manually flip the hollow shell 1 and change the distribution of the metal balls 106 to achieve autonomous adjustment of the oxygen flow, which is suitable for patients with good autonomous breathing ability.

[0048] Refer to the attached Figure 4As shown, specifically, the diffusion amount adjusting member 104 includes a base plate 1041, which is connected to the connecting rod 105. The base plate 1041 is evenly distributed with pillars 1042, which extend in a direction close to the porous plate 101 and correspond one-to-one to the oxygen diffusion holes 1011. The upper ends of the pillars 1042 are connected with tapered plugs 1043, and the small diameter ends of the tapered plugs 1043 are inserted into the oxygen diffusion holes 1011. When the insertion depth of the tapered plugs 1043 and the oxygen diffusion holes 1011 is shallow, the oxygen diffusion holes 1011 are far away from the large diameter ends of the tapered plugs 1043, that is, the oxygen diffusion holes 1011 are relatively close to each other. The air outlet area of ​​the diffuse hole 1011 is larger, the oxygen flow rate is larger, and when the insertion depth between the conical plug 1043 and the oxygen surface is deeper, the oxygen diffusion hole 1011 is closer to the large diameter end of the conical plug 1043, that is, the initial area of ​​the oxygen diffusion hole 1011 is smaller and the oxygen flow rate is smaller; when the partition plate 102 is tilted, the base plate 1041 also produces a corresponding tilt displacement, and drives the conical plug 1043 to be tilted through the support 1042, so that the insertion depth between the conical plug 1043 and the corresponding oxygen diffusion hole 1011 increases or decreases, so as to achieve the regulation of the oxygen flow rate.

[0049] Refer to the attached Figure 2 As shown, more specifically, a conductor 107 is connected between the partition plate 102 and the hollow shell 1. Conductor 107 can be a coil winding or a metal block, as long as it can be energized. Conductor 107 is used to connect to an external power source. When the external power source energizes conductor 107, it generates a magnetic field. Under the action of the magnetic field, the metal balls 106 are evenly distributed on the partition plate 102. At this time, the compression reset body 103 at the four corners of the partition plate 102 is subjected to the same pressure. The insertion depth between the tapered plug 1043 and the oxygen diffusion hole 1011 remains the same, and the insertion depth is the shallowest, indicating the maximum oxygen supply state. The maximum oxygen supply state is suitable for patients who have just completed surgery and have poor spontaneous breathing ability.

[0050] Working principle: first, the hollow shell 1 of the oxygen dispersion module is connected with the external oxygen supply device, the oxygen output by the oxygen supply device will enter the hollow shell 1 and disperse along the oxygen dispersion hole 1011 of the porous plate 101, and the patient inhales, in specific use, if the patient just finished the operation, the autonomous breathing ability is poor, the electrically conductive body 107 can be energized, the metal ball 106 is uniformly distributed on the partition plate 102, at this time, the compression reset body 103 at the four corners of the partition plate 102 is compressed and the deformation amount is the same, at this time, the depth of the conical plug 1043 and the corresponding oxygen dispersion hole 1011 is the shallowest, the oxygen dispersion module is in the maximum oxygen supply state, and the oxygen demand of the patient in this stage is met; if the patient is in the rehabilitation stage, the autonomous breathing ability is strong, the angle of the hollow shell 1 can be manually turned over, the distribution position of the metal ball 106 in the hollow shell 1 is changed, so that the depth of the conical plug 1043 and the oxygen dispersion hole 1011 is changed, so as to adjust the oxygen flow to meet the autonomous oxygen demand of the patient, and avoid the waste of oxygen resources.

[0051] Specific application case: a patient in the thoracic surgery department of a hospital has impaired respiratory muscle function, resulting in limited autonomous breathing function, if oxygen is not supplied in time, hypoxemia is easy to be caused, therefore, the patient needs to be supplied with oxygen from the outside world to maintain the normal body function, the specific application process of the oxygen dispersion module of the application to the patient is as follows: 1, preparation: assist the patient to keep a comfortable lying posture, put the oxygen dispersion module on the patient's mouth and nose, and connect the oxygen dispersion module with the external oxygen supply device.

[0052] 2, keep the maximum oxygen supply: connect the electrically conductive body 107 with the external power supply, energize the electrically conductive body 107, make the metal ball 106 uniformly distributed on the partition plate 102, the compression reset body 103 at the four corners of the partition plate 102 is uniformly stressed, the depth of the conical plug 1043 and the oxygen dispersion hole 1011 is kept the shallowest, that is, the oxygen supply is the largest, which is beneficial to the recovery of the patient's body function and the improvement of the autonomous breathing ability.

[0053] 3, the patient's autonomous breathing function improves: after inhaling the maximum oxygen supply for a period of time, the patient's body function recovers and the autonomous breathing function improves, the patient can adjust the oxygen supply according to the oxygen demand.

[0054] 4, self-regulation of oxygen supply: the patient manually turns over the hollow shell 1, the position distribution of the metal ball 106 in the hollow shell 1 changes, the compression reset body 103 at the four corners of the partition plate 102 produces different deformation, so that the depth of the conical plug 1043 and the oxygen dispersion hole 1011 changes, that is, the oxygen supply can be adjusted.

[0055] Through the above steps, the oxygen diffusion module of the present invention can be applied to patients at different recovery stages after surgery to meet the oxygen inhalation needs of patients at different stages. Patients can independently adjust the oxygen supply according to their own conditions and gradually improve their autonomous breathing ability.

[0056] Example 2: Example 2 Based on Example 1, a portable pressure-adjustable oxygen inhalation device is provided. The portable pressure-adjustable oxygen inhalation device includes the oxygen diffusion module in Example 1. Figure 6-13 As shown, the portable adjustable pressure oxygen inhalation device includes a wearable main body 2 with a cavity. The wearable main body 2 is provided with an oxygen supply and humidification system, and does not need to be connected to external oxygen supply equipment. The wearable main body 2 is connected with a neck fixing belt 201 and a waist fixing belt 202 for patients to wear, so that patients can carry it independently during walking exercises without the need for family members or medical staff to accompany them.

[0057] Specifically, refer to the attached Figure 6-7 As shown, the portable adjustable pressure oxygen inhalation device of the present invention also includes an air pump 3, which is connected to the wearable main body 2. The air pump 3 is connected to the neck pillow airbag 4 and the cavity of the wearable main body 2 respectively. The neck pillow airbag 4 is an arc-shaped flexible hollow structure, which is connected to the wearable main body 2. When the air pump 3 inflates the neck pillow airbag 4, the neck pillow airbag 4 deforms and supports the patient's head and neck. At the same time, the neck pillow airbag 4 can adjust the angle between the patient and the bed, improve the patient's comfort in bed, and facilitate the patient's autonomous breathing; an angle adjustment member 5 is provided in the cavity of the wearable main body 2. When the air pump 3 inflates the cavity, the angle adjustment member 5 can realize the flip adjustment of its own angle under the action of air pressure. The angle adjustment member 5 is connected to the oxygen supply pipe 6. The oxygen supply pipe 6 is a lightweight hollow pipe, connected to the angle adjustment member 5 and flipped with the angle adjustment member 5. The end of the oxygen supply pipe 6 is connected to the oxygen diffusion module, and the oxygen diffusion module can be flipped with the oxygen supply pipe 6 to realize the angle adjustment of the oxygen diffusion module. The oxygen diffusion module mentioned here is consistent with the above-mentioned oxygen diffusion module, and its structure is not described here in detail.

[0058] Refer to the attached Figure 8As shown, more specifically, the angle adjustment member 5 includes a pneumatic plate 501, a sleeve 502 is connected at the center of the pneumatic plate 501, and stretching reset members 505 are connected at both ends of the pneumatic plate 501. The pneumatic plate 501 is slidably connected to the inner wall of the cavity of the wearable main body 2, and a toothed shaft 503 is sleeved inside the sleeve 502. One end of the toothed shaft 503 is rotatably connected to the sleeve 502, and the other end is matched with a toothed transmission rod 504. The toothed transmission rod 504 is also matched with the oxygen supply tube 6. When the air pump 3 inflates the cavity of the wearable main body 2, the pneumatic plate 501 moves horizontally under the action of air pressure, and the sleeve 502 moves horizontally with the pneumatic plate 501. The toothed shaft 503 inside the sleeve 502 outputs the linear movement as rotation, and the toothed transmission rod 504 connected to the toothed shaft 503 also rotates accordingly, realizing the flip adjustment of the angle adjustment member 5 itself. In this process, the stretching and restoring members 505 at both ends of the pneumatic plate 501 are stretched and generate a restoring force. If inflation is stopped, the pneumatic plate 501 will be reset under the restoring force of the stretching and restoring member 505, and the angle adjustment member 5 will also be reset to the initial angle.

[0059] More specifically, the toothed transmission rod 504 includes a transmission shaft 5041, the middle part of the transmission shaft 5041 is sleeved with a driven bevel gear 5042 which is connected to the toothed rotating shaft 503, and both ends of the transmission shaft 5041 are sleeved with end gears 5043 which are connected to the oxygen supply tube 6. The transmission shaft 5041 is arranged perpendicular to the toothed rotating shaft 503, and the toothed rotating shaft 503 is sleeved with active bevel gears 5031 which mesh with the driven bevel gears 5042. When the toothed rotating shaft 503 rotates, it will drive the active bevel gears 5031 to rotate, and the driven bevel gears 5042 which mesh with it will rotate accordingly and drive the transmission shaft 5041 to rotate, thereby driving the end gears 5043 at both ends of the transmission shaft 5041 to rotate, so as to realize the rotation of the oxygen supply tube 6 which is connected to the end gears 5043.

[0060] Refer to the attached Figure 9-10 As shown, the oxygen supply pipe 6 includes an air pipe 601 and a toothed connecting end 602. One end of the air pipe 601 is connected to the hollow shell 1 of the oxygen diffusion module, and the other end is connected to the toothed connecting end 602. The toothed connecting end 602 is a hollow annular structure and is connected to the oxygen supply humidification system. A matching gear 6021 engaged with the end gear 5043 is provided on its outer side. When the end gear 5043 on the transmission shaft 5041 rotates, the matching gear 6021 engaged with the end gear 5043 will drive the toothed connecting end 602 to rotate, thereby realizing the rotation of the oxygen supply pipe 6.

[0061] Refer to the attached Figure 11-12As shown, the specific structure of the toothed shaft 503 that outputs the linear movement of the sleeve 502 into rotation is: a protrusion 5032 is provided on the outer wall of the toothed shaft 503, and a spiral groove 5021 adapted to the protrusion 5032 is provided on the inner wall of the sleeve 502. When the sleeve 502 moves horizontally with the pneumatic plate 501, the protrusion 5032 fits in the spiral groove 5021 and moves along the spiral groove 5021, thereby realizing the output of the horizontal movement of the sleeve 502 into the rotation of the toothed shaft 503.

[0062] Refer to the attached Figure 13 As shown, the portable adjustable pressure oxygen inhalation device of the present invention also includes a control module 7 connected to the wearable main body 2, chest pressure airbags 8 connected to both sides of the wearable main body 2, and a back slapping module 9 connected to the wearable main body 2. The chest pressure airbag 8 is an arc-shaped structure, which will fit closely to the patient's chest contour after inflation. A pressure sensor 801 is provided in the chest pressure airbag 8. The pressure sensor 801 can monitor the patient's chest cavity fluctuations, thereby judging the patient's breathing status. The pressure sensor 801 will convert the monitored chest pressure value into an electrical signal and send it to the control module 7. The control module 7 can receive the electrical signal of the pressure sensor 801 and control the back slapping module 9 to start, slap the patient's back to reduce sputum accumulation in the lungs and assist the patient's breathing.

[0063] The control module 7 includes an alarm and a motor 701, both of which are electrically connected to the pressure sensor 801. The motor 701 is also electrically connected to the back patting module 9. When the chest pressure is lower than the minimum pressure value, the control module 7 controls the alarm to sound an alarm. When the chest pressure is higher than the maximum pressure value, the control module 7 controls the motor 701 to start forward and reverse rotation, and the motor 701 drives the back patting module 9 to work. For patients at different stages, if the patient is in bed rest, his chest rises and falls less, and the pressure value received by the pressure sensor 801 is smaller. If the chest pressure is less than the set minimum pressure value, the control module 7 will control the alarm to sound an alarm, reminding medical staff to pay attention to the patient's condition to prevent the patient from oxygen poisoning; because the patient is bedridden for a long time, sputum is easily accumulated in the lungs. The patient's sputum excretion ability is higher in the walking exercise stage than in the bed rest stage, and the patient's chest rises and falls more in this stage, and the pressure value received by the pressure sensor 801 is larger. If the chest pressure is greater than the set maximum pressure value, the control module 7 controls the motor 701 to start, driving the back patting module 9 to pat the patient's back, which can promote the patient to expectorate, relieve the patient's chest pressure, and improve the patient's respiratory function.

[0064] Refer to the attached Figure 13As shown, specifically, the back patting module 9 includes a driving shaft 901 and a patting blade 902. The driving shaft 901 is connected to the motor 701 and rotates forward and reverse with the motor 701. The patting blade 902 is connected to both sides of the driving shaft 901 and is evenly distributed along the axial direction of the driving shaft 901. It rotates with the driving shaft 901 to pat the patient's back.

[0065] Refer to the attached Figure 7 As shown, more specifically, nasal catheters 203 are connected to both sides of the wearable body 2. The nasal catheters 203 are connected to the oxygen supply and humidification system. If the patient needs high-flow oxygen inhalation, the nasal catheters 203 can be inserted into the patient's nasal cavity to meet the patient's oxygen inhalation needs.

[0066] More specifically, the oxygen supply and humidification system includes an oxygen supply chamber 10 and a humidification module 11. The oxygen supply chamber 10 and the humidification module 11 are interconnected to deliver oxygen to the nasal catheter 203 and the oxygen diffusion module respectively to meet the patient's oxygen inhalation needs.

[0067] Working principle: First, the patient wears the portable adjustable pressure oxygen inhalation device through the neck fixing belt 201 and the waist fixing belt 202, and then inflates the neck pillow airbag 4 through the air pump 3 to adjust the angle between the head of the bedridden patient and the bed. The air pump 3 is used to inflate the cavity of the wearable main body 2, so that the pneumatic plate 501 drives the sleeve 502 to move horizontally under the action of air pressure, drives the toothed rotating shaft 503 to rotate, and drives the toothed transmission rod 504 to rotate, realizing the flip adjustment of the angle adjustment part 5 itself, and the toothed transmission rod 504 drives the toothed connecting end 602 to rotate, realizing the rotation of the oxygen supply tube 6, and the oxygen supply tube 6 drives the oxygen diffusion module The metal balls 106 are rotated to change their distribution, thereby realizing the regulation of the oxygen flow by the oxygen diffusion module. At the same time, the pressure sensor 801 monitors the chest pressure of the patient. When the pressure value received by the pressure sensor 801 is less than the set minimum pressure value, the control module 7 controls the alarm to sound an alarm, reminding medical staff to pay attention to the patient's condition and avoid oxygen poisoning of the patient. When the pressure value received by the pressure sensor 801 is greater than the set maximum pressure value, the control module 7 controls the motor 701 to start forward and reverse rotation, driving the back patting module 9 to pat the patient's back, so as to promote the patient's expectoration, relieve the patient's chest pressure, and reduce sputum accumulation.

[0068] Specific application case: A patient in the thoracic surgery department of a hospital has just finished an operation. The surgical anesthetic has limited the patient's spontaneous breathing function and requires the use of an oxygen inhalation device to supplement oxygen in order to maintain normal body functions. The specific application process of the portable adjustable pressure oxygen inhalation device of the present invention to supply oxygen to the patient is as follows: 1. Preparation: Wrap the neck fixing belt 201 of the portable adjustable pressure oxygen inhalation device around the patient's neck and the waist fixing belt 202 around the patient's waist, and then help the patient maintain a more comfortable lying position.

[0069] 2. Adjust the angle between the patient's head and the bed: Turn on the air pump 3 to inflate the cervical pillow airbag 4, so that the cervical pillow airbag 4 swells to support the patient's head and neck. By adjusting the degree of inflation of the cervical pillow airbag 4, the angle between the patient's head and the bed can be adjusted.

[0070] 3. Start oxygen supply: According to the patient's oxygen demand, select the nasal catheter 203 or the oxygen diffusion module to supply oxygen to the patient.

[0071] 4. Adjust the angle between the device and the patient's mouth and nose: Inflate the cavity of the wearable body 2 through the air pump 3, so that the angle adjustment member 5 moves under the action of air pressure, thereby realizing the flipping of the angle adjustment member 5, and driving the flipping of the oxygen supply tube 6 and the oxygen diffusion module to achieve the angle adjustment between the oxygen diffusion module and the patient's mouth and nose.

[0072] 5. Adjusting the oxygen supply: When the oxygen diffusion module flips with the angle adjustment member 5 to adjust the angle between the oxygen diffusion module and the patient's mouth and nose, the distribution of the metal balls 106 in the oxygen diffusion module changes, so that the insertion depth of the tapered plug 1043 and the oxygen diffusion hole 1011 changes, thereby adjusting the oxygen supply.

[0073] 6. Monitor the patient's respiratory status: inflate the chest pressure airbag 8 so that the chest pressure airbag 8 fits the patient's chest contour. The pressure sensor 801 in the chest pressure airbag 8 detects the patient's chest pressure. When the chest pressure is lower than the minimum pressure value of the pressure sensor 801, the control module 7 controls the alarm to sound an alarm; when the chest pressure is higher than the maximum pressure value of the pressure sensor 801, the control module 7 controls the back patting module 9 to pat the patient's back to promote the patient to expel the sputum squeezed from the lungs and improve the patient's autonomous breathing ability.

[0074] Through the above steps, the portable adjustable pressure oxygen inhalation device of the present invention can be carried by patients independently without the need for medical staff and family members to accompany them. It can adjust the angle between the patient's head and the bed to improve the patient's lying comfort. It can adjust the angle between the oxygen diffusion module and the patient's mouth and nose. It is suitable for patients in different recovery stages after surgery and meets the oxygen inhalation needs of patients at different stages. It can monitor the chest pressure of patients in lying and walking states, and assist patients in improving their autonomous breathing ability.
