Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a fully automatic medical auxiliary breath-holding device. Background Technology

[0002] With the increasing sophistication of medical radiological examination equipment such as medical X-ray machines, CT scanners, and MRI machines, radiological examinations have become a common clinical examination, playing an important role in the initial screening, localization, and characterization of diseases.

[0003] In current CT scans, some areas require the patient to hold their breath during the procedure (such as coronary artery CT scans and contrast-enhanced chest and abdominal CT scans). If the patient does not breathe properly, the images produced by the CT scan will be blurred due to the movement caused by breathing, making it difficult for the diagnostician to observe the images carefully, ultimately leading to CT scan failure. Secondly, patients also need to receive iodine contrast agents during this procedure. If the scan fails due to poor breathing, the repeated overuse of iodine contrast agents can cause liver and kidney damage. Thirdly, to minimize unnecessary radiation exposure during CT scans, the best protective method is to cooperate with the doctor and technician's instructions, breathe properly, and avoid repeating CT scans in a short period of time. Therefore, a device is needed to assist patients in holding their breath during CT scans.

[0004] Chinese Patent Publication No. CN221356866U discloses a breath-holding assist device for abdominal magnetic resonance imaging (MRI) examination. The device includes a chest airbag, an abdominal airbag, a support pad, a connecting tube, a connecting rope, a first-order Velcro strap, a second-order Velcro strap, an air nozzle, a sealing plug, a sponge, and silicone. The chest airbag and abdominal airbag are fixedly connected by the connecting tube, and the abdominal airbag and support pad are fixedly connected by the connecting rope. First-order Velcro straps are installed on both sides of the chest airbag, and second-order Velcro straps are installed on both sides of the abdominal airbag. Air nozzles are installed on the surface of both the chest and abdominal airbags, and a sealing plug is provided at the top of each air nozzle. In actual use, by configuring the chest airbag, abdominal airbag, support pad, connecting tube, connecting rope, first-order Velcro strap, second-order Velcro strap, air nozzle, sealing plug, sponge, and silicone, the patient can largely switch to abdominal breathing and hold their breath for a longer time, thus maximizing image quality.

[0005] Chinese Patent Publication No. CN212281374U discloses a breath-holding assist device, comprising: a control module for controlling the operation of the breath-holding assist device; a body having a receiving groove for accommodating a patient's head; a nasal breath-holding module, communicatively connected to the control module and operating under the control of the control module to close the patient's nose; and a mouth breath-holding module, communicatively connected to the control module and operating under the control of the control module to close the patient's mouth. Compared with the prior art, the breath-holding assist device provided by this invention uses the receiving groove to fix the patient's head during radiological examinations, which is beneficial for the examination. Simultaneously, by using the nasal and mouth breath-holding modules to seal the patient's nose and mouth respectively, the patient is unable to breathe through their nose and mouth, automatically entering a breath-holding state, thus improving the efficiency of radiological examinations.

[0006] Medical breath-holding aids like those described above have simple functions, insufficient automation and applicability, and lack the ability to fix the patient's head. They are easily affected by the patient's head movements, and for some patients who cannot hold their breath voluntarily, elderly patients, and deaf-mute patients, whose cooperation is poor, the movement caused by the patient's breathing can create a blurring effect, making it difficult for the diagnostic doctor to carefully observe the examination images. This results in a low success rate and low image quality, requiring repeated examinations, which is time-consuming and laborious. Furthermore, it cannot eliminate the patient's tension during the examination, which can easily affect the patient's breath-holding duration and effectiveness. Summary of the Invention

[0007] The purpose of this invention is to provide a fully automatic medical auxiliary breath-holding device, which overcomes the problems of existing medical breath-holding auxiliary devices, such as simple functions, insufficient automation and applicability, lack of ability to fix the patient's head, easy influence of the patient's head movement on the breath-holding effect, and poor cooperation from patients who cannot hold their breath independently, elderly patients, and deaf-mute patients, which can lead to low examination success rate and low image quality, requiring repeated examinations, which is time-consuming and laborious, and cannot eliminate the patient's tension during the examination, which can easily affect the patient's breath-holding duration and effect.

[0076] Example 1

[0077] like Figure 1-24 As shown, this invention provides a fully automatic medical assisted breath-holding device, including an inflatable pressure abdominal binder 1 placed on the patient's abdomen. The inflatable pressure abdominal binder 1 can be used alone to compress and remind elderly patients or those with poor expiratory function to hold their breath. Simultaneously, the pressure from the inflatable pressure abdominal binder 1 restricts the movement of the patient's abdominal wall, minimizing respiratory motion artifacts caused by poor respiratory coordination and improving image quality. It also includes an inflatable pressure nose clip mechanism 4 for squeezing the patient's nose and lips. This mechanism simultaneously blocks the patient's nose and mouth, preventing mouth breathing during breath-holding and improving efficiency. Patient cooperation during the examination also includes the head support and fixation base 2, which has a U-shaped groove structure and a protective pad 21 inside for supporting and fixing the patient's head, avoiding image blurring and jagged artifacts caused by head rotation during the examination, thus improving image quality. The inflatable and pressurized nose clip mechanism 4 is set on the head support and fixation base 2. The main control box 6 contains three sets of air pump assemblies 66. The three sets of air pump assemblies 66 are respectively connected to the inflatable and pressurized abdominal belt 1 and the inflatable and pressurized nose clip mechanism 4 through three air supply pipes 9. The main control box 6 is wirelessly connected to the remote control box 5. The cooperation between the remote control box 5 and the main control box 6 can improve the automation level of the device.

[0078] Specifically, the main control box 6 is also equipped with a control component, which is electrically connected to the air pump assembly 66 and is used to control the opening or closing of the air pump assembly 66 to improve its control convenience.

[0079] Specifically, the air pump assembly 66 includes an air pump 661, which is a small DC diaphragm air pump. The output end of the air pump 661 is connected to a four-way connector 662, which is connected to the air supply pipe 9 via a fourth connecting pipe 663. A pressure relief solenoid valve 665 and a pressure sensor 664 are connected to the four-way connector 662. The air pump 661, pressure relief solenoid valve 665, and pressure sensor 664 are all electrically connected to the control assembly. Therefore, the air pump 661 can be used to inflate and deflate the inflatable abdominal binder 1 and the inflatable nasal clip mechanism 4. For elderly patients or those with poor breathing, this can be used independently. Using an inflatable pressure abdominal binder 1 to apply pressure can remind the patient to hold their breath. At the same time, the pressure from the inflatable pressure abdominal binder 1 can restrict the movement and fluctuation of the patient's chest wall, abdominal wall, and diaphragm, minimizing respiratory motion artifacts caused by poor respiratory coordination, improving image quality, and meeting diagnostic requirements. At the same time, using the inflatable pressure nose clip mechanism 4 to apply pressure can directly replace the presence of family members to pinch the patient's nose and assist with breath-holding, avoiding radiation damage to the patient's family members. For patients with chest and abdominal injuries or who are not suitable for using the inflatable pressure abdominal binder, it is recommended to use only the inflatable pressure nose clip mechanism 4.

[0080] Specifically, the inflatable pressure abdominal binder 1 has a compression airbag 11 located in the middle of its inner side. The compression airbag 11 is equipped with a first connecting tube 12, which is connected to the air pump assembly 66 via an air supply tube 9. This allows the air pump assembly 66 to inflate and deflate the compression airbag 11, prompting the patient to hold their breath and improving patient cooperation. This ensures the clarity and success rate of images during CT scans. The compression airbag 11 has multiple airbag blocks 13. The inflatable pressure abdominal binder 1 has connectors 14 at both ends. The connectors 14 are connected to both ends of the inflatable pressure abdominal binder 1 via elastic straps to accommodate patients of different body sizes. The connectors 14 can be interlocking Velcro or snap fasteners to secure the inflatable pressure abdominal binder 1 to the patient.

[0081] Specifically, the inflatable pressurized nose clip mechanism 4 is connected to the head support fixing seat 2 via the mask 3. The mask 3 is connected to the top of the head support fixing seat 2 via a strap 31. The inflatable pressurized nose clip mechanism 4 includes a nose clip 41, which has a U-shaped elastic clip structure. A clamping groove 32 is provided on the top of the mask 3. The nose clip 41 is connected to the clamping groove 32 on the top of the mask 3 via a support member 43, so that the patient's nose can be exposed from the clamping groove 32 and clamped by the nose clip 41. The nose clip airbag 42, which is a small airbag, is set at the opening of the nose clip 41 to assist the nose clip 41 in clamping and holding the patient's nose. The nose clip airbag 42 also plays a cushioning role, relieving the discomfort caused by the clamping of the nose clip 41. The device is connected to a ventilation seat 44 via a second connecting tube 442. The ventilation seat 44 is connected to an air supply tube 9. Gas is inflated into the nasal clip airbag 42 via the air supply tube 9 to achieve the function of pressurizing or depressurizing. The ventilation seat 44 is connected to a compression airbag 33 on the inside of the mask 3 via a third connecting tube 441. The compression airbag 33 is used to block the patient's mouth to prevent the patient from breathing through their mouth while holding their breath. At the same time, the nasal clip 41, the nasal clip airbag 42, and the compression airbag 33 on the mask 3 can prevent adverse effects caused by the patient pinching their nose or family members inserting their hands into the magnet hole to assist in pinching their nose. This improves the patient's examination comfort and cooperation, reduces the burden on accompanying family members, and further improves the effect of MRI chest and abdominal examinations.

[0082] Specifically, a first display screen 61 is installed on the top of the main control box 6 to display the working status of various components inside the main control box 6. It can detect and display the respiratory wave, the pressure of the inflatable abdominal band 1 and the inflatable nasal clip mechanism 4 in real time. The respiratory wave and pressure display are provided by the pressure sensor 664. On the outside of the first display screen 61, there is a first emergency stop switch 63 for controlling the air pump assembly 66 and three air pump pressure indicator lights 62 to display the air pump pressure. The three air pump pressure indicator lights 62 are distinguished by red, green and blue respectively. Red indicates that the pressure is too high, green indicates that the pressure is normal and blue indicates that the pressure is too low. In conjunction with the pressure value changes of the three pressure sensors on the first display screen, it can be known which pressure sensor has a problem with excessive or insufficient air pressure. There is a knob-type pressure adjustment switch on the surface of the main control box. Since each patient has a different tolerance to the pressure of the abdominal band and nasal clip balloon, the CT technician or nurse needs to set the pressure threshold in advance during training. The knob-type pressure adjustment switch is adjusted separately first, and the optimal breath-holding pressure value for the first patient is set according to the patient's breath-holding effect. A TipyC firmware burning interface 68 is provided on the side wall of the main control box 6 to learn voice commands.

[0083] The main control box 6 has a first base plate 65 at its bottom, and a voice recognition chip 651 is installed on the base plate 65 to recognize voice commands. The main control chip 652 is wirelessly connected to the remote WiFi control box 5 via a Bluetooth WiFi control chip 653 for data synchronization and control. A relay switch 654 is connected to the main control chip 652 and is used to control the inflation or deflation of the air pump assembly 66. A reset switch 656 is connected to the main control chip 652 and serves to protect the main control box 6 and restore it to its normal working state. A speaker 64 is connected to the main control chip 652 and is used to play voice commands. An onboard high-gain microphone 67 is connected to the main control chip 652 and is used to receive voice commands. A removable 12V lithium battery is installed on the rear side of the main control box 6 and is connected to various components inside the main control box 6 via a power circuit 655 to provide power to these components.

[0084] Meanwhile, a second display screen 51 is installed on the top of the remote control box 5, which is electrically connected to the main control chip 541 inside the remote control box 5. It is remotely synchronized with the first display screen 61 and can display the breathing wave, the pressure of the inflatable abdominal belt 1 and the inflatable nasal clip mechanism 4 in real time. The breathing wave and pressure display are provided by the pressure sensor 664 inside the main control box 6 and transmitted through the Bluetooth WiFi control chip. A second emergency stop switch 53 and three air pressure pump pressure indicator lights 52 are installed on the outside of the second display screen 51, which are also distinguished by red, green and blue colors and are electrically connected to the main control chip 541. A second base plate 54 is installed at the bottom of the remote control box 5, and the main control chip 541 is installed on the base plate. On the second base plate 54, there is also a power supply circuit 544, which is electrically connected to the main control chip 541; a speaker 542, which is electrically connected to the main control chip 541; a Bluetooth WiFi control chip 543, which is electrically connected to the main control chip 541 and wirelessly connected to the Bluetooth WiFi control chip 653 of the main control box 6. This allows for remote wireless acquisition of signals from various components within the main control box 6 and remote wireless control of the operating status of these components. Additionally, there is a 5V safety lithium battery pack 545, a power switch 546, and a Tipy-C 5V DC input socket 547 to meet the power requirements of various components within the remote control box 5.

[0085] Specific implementation examples:

[0086] Before a CT scan, the CT scanner issues an inhalation command: "Inhale, hold your breath!" After the scan, it issues an exhalation command: "You can breathe now!" This invention uses a voice recognition chip 651 and an onboard high-gain microphone 67 to recognize these two sets of sounds. The main control chip 652 sends a start command to the power circuit 655, energizing the relay switch 654 and initiating the air pump assembly 66. Inflation is performed via pressure sensor 664 to the inflatable abdominal band 1 and the nasal clip airbag 42. The inflation process should be controlled within 5 seconds. During the process, once the pressure sensor 664 senses that the pressure has reached the working set value, the main control chip 652 immediately issues a command to stop the inflation, the relay switch 654 cuts off the power and stops the operation, and the CT scan starts immediately. After the scan is completed, the CT machine issues an exhalation command: "You can breathe now!" The voice recognition chip 651 and the onboard high-gain microphone 67 receive the voice and recognize it. The main control chip 652 issues a start command to the control power circuit 655, and the pressure relief solenoid valve 665 deflates the inflatable abdominal band 1 and the nasal clip airbag 42. The deflation process should be controlled within 4 seconds.

[0087] Throughout the process, the pressure measured by the pressure sensor 664 is displayed on the first display screen 61 of the main control box 6 of the device, and synchronously displayed on the second display screen 51 of the Bluetooth WIFI remote control box 5 via Bluetooth WIFI mode. The CT technician can select the start time of the CT scan in real time by observing the respiratory waves displayed on the second display screen 51 of the Bluetooth WIFI remote control box 5. Generally, the scan will start when the patient's respiratory waves are stable, that is, after the patient begins to hold their breath.

[0088] It is worth noting that the use of the entire device requires instruction and rigorous training before the patient's examination to avoid serious harm to the patient due to improper operation.

[0089] The training method is as follows: Since each patient has a different tolerance to the pressure of the inflatable abdominal binder 1 and the nasal clip airbag 42, the CT technician or nurse needs to set the pressure threshold in advance during training. First, adjust the pressure sensor 664 using the adjustment knob, and set the optimal breath-holding pressure value for the first patient based on their breath-holding performance. The purpose is to ensure safer and more effective breath-holding for the patient, preventing excessive pressure from causing harm. In extreme cases, if the inflation pressure exceeds the set value, or if the pressure relief solenoid valve 665 fails to function properly for an extended period, the CT technician will immediately observe the alarm on the second display screen 51 of the Bluetooth / WIFI remote control box 5, press the emergency stop button, and remotely de-energize the relay switch 654 to stop inflating the inflatable abdominal binder 1 and the nasal clip airbag 42. The technician should immediately go to the patient and disconnect the inflatable nasal clip mechanism 4 from the inflatable abdominal binder 1.

[0090] Example 2

[0091] like Figure 1 , Figure 3-6 , Figure 14-18 and Figure 25 As shown, a massage mechanism is also provided on the head support fixture 2. The massage mechanism is connected to the main control box 6 via an air supply pipe 9. The massage mechanism includes a shoulder massage component 7, which is located at the bottom front side of the head support fixture 2 and is used to massage the patient's shoulders. The shoulder massage component 7 is connected to a drive component 10 located inside the head support fixture 2, and an acupoint massage component 8, which is located at the upper inner side of the head support fixture 2 and is used to massage the patient's temples. The acupoint massage component 8 is connected to the drive component 10, and the drive component 10 is connected to the air pump component 66 via the air supply pipe 9. By driving the shoulder massage component 7 and the acupoint massage component 8 to massage the patient's shoulders and temples during the patient's breath-holding process, the drive component 10 can eliminate the patient's tension, provide positive stimulation to the brain, eliminate mental fatigue, reduce respiratory rate, improve concentration during subsequent breath-holding, and effectively prolong the breath-holding time and improve the breath-holding effect.

[0092] Specifically, the drive assembly 10 includes a dual-head drive unit, located inside the front of the head support fixing seat 2, and connected to the air pump assembly 66 via an air supply pipe 9. A rotating rod 102 is connected to the dual-head drive unit. A first transmission component is located in the middle of the rotating rod 102 and connected to the shoulder massage assembly 7. The first transmission component consists of a first bevel gear 103 and a second bevel gear 72 that mesh with each other. The rotating rod 102 drives the first bevel gear to rotate, which in turn drives the shoulder massage assembly 7 to perform shoulder massage through the second bevel gear 72. A second transmission component is located at the end of the rotating rod 102 and connected to the acupoint massage assembly 8. The second transmission component consists of a first pulley 104 and a second pulley 85 that are powered by a belt 105. The first pulley 104 is connected to the end of the rotating rod 102, and the second pulley 85 is connected to the acupoint massage assembly 8. Thus, the drive assembly 10 can drive the shoulder massage assembly 7 and the acupoint massage assembly 8 to massage the patient's shoulders and temples to relieve the patient's tension.

[0093] Specifically, the shoulder massage component 7 includes a mounting shell 71, which is embedded in the bottom front side of the head support fixing seat 2. A first rotating shaft 73 is rotatably connected to the inner side of the mounting shell 71. The first rotating shaft 73 is connected to the second bevel gear 72 of the first transmission component to drive the shoulder massage component 7 to complete the shoulder massage work. A rotating block 74 is disposed in the mounting shell 71. The rotating block 74 is connected to the first rotating shaft 73 through a rotating seat 77. The first rotating shaft 73 is slidably connected in the rotating seat 77. At least three first massage heads 75 are arranged in a ring on the outer end face of the rotating block 74. A buffer is also included. 76 can be a spring, sleeved on the first rotating shaft 73 and abutting against the preset rotating block 74 in the mounting shell 71, used to realize the extension and retraction of the first massage head 75. Thus, during the process of the first rotating shaft 73 driving the rotating block 74 to massage the patient's shoulder, the extension and retraction of the first rotating shaft 73 in the rotating seat 77, combined with the elastic effect of the buffer 76, allows the rotating block 74 to extend and retract within the mounting shell 71, thereby enabling the first massage head 75 to adaptively extend and retract during the massage process, improving the patient's comfort.

[0094] Specifically, the acupoint massage component 8 includes an eccentric wheel 83, which is disposed on the upper inner side of the head support fixing seat 2. Fixing plates 22 are respectively disposed on both sides inside the head support fixing seat 2. A movable groove 221 is formed on the upper side of the fixing plate 22, and the eccentric wheel 83 is disposed within the movable groove 221. The eccentric wheel 83 is connected to the second pulley 85 of the second transmission component via a second rotating shaft 84. A swing rod 81 is connected in the middle to the edge of the eccentric wheel 83, and a second massage head 82 located inside the head support fixing seat 2 is connected to the upper end of the swing rod 81. The second massage head 82 is located on the outer top of the fixing plate 22. The lower end of 81 is connected to a connecting rod 86, which assists the swing rod 81 in reciprocating motion. During the temple massage, the second transmission component drives the second rotating shaft 84 to rotate through the second pulley 85, which in turn drives the eccentric wheel 83 to rotate. By utilizing the rotational connection between the eccentric wheel 83 and the middle of the swing rod 81, the actuating rod 81 can be driven to swing within the movable groove 221, thereby increasing the swing of the swing rod 81 and causing the second massage head 82 to reciprocate. Through this reciprocating motion, the patient's temples can be massaged, so that the patient's head can be relaxed, fatigue can be eliminated, and the concentration of subsequent breath-holding can be improved, thus enhancing the breath-holding effect.

[0095] Specifically, the dual-head drive unit includes a housing 101, which is connected to the bottom front side of the head support base 2 via a connecting block. A rotating column 1011 is connected inside the housing 101 via a rotating rod 102. An air outlet 1015 and an air inlet 1016 are respectively provided on the upper and lower sides of the housing 101. The air inlet 1016 is connected to an air supply pipe 9. Multiple drive blades 1013 are arranged in a ring array on the outer arc surface of the rotating column 1011. The outer ends of the drive blades 1013 do not contact the inner wall of the housing 101. When massage is required... Gas can be injected into the housing 101 through the air pump assembly 66 via the air pipe 9 from the air inlet 1016, and then discharged from the air outlet 1015, forming an airflow. This airflow can be used to drive the fan blades 1013 to move. The fan blades 1013 arranged in a ring on the rotating column 1011 can drive the rotating column 1011 to rotate inside the housing 101, which in turn drives the rotating rod 102 to rotate. The rotating rod 102 drives the shoulder massage assembly 7 and the acupoint massage assembly 8 to perform massage work through the first transmission component and the second transmission component, respectively.

[0096] Furthermore, the drive blade 1013 can be configured as a blade with a certain curvature, so that the air inlet 1015 can be directly facing the curved position, in order to reduce the resistance required for drive and improve its expected effect.

[0097] It should be noted that in this invention, the air pump assembly 66 is provided in three sets, each connected to a different air supply pipe 9. Each air supply pipe 9 is connected to the nose clip airbag 42 and the compression airbag 33 in the inflatable and pressurized nose clip mechanism 4, the compression airbag 11 on the inflatable and pressurized abdominal belt 1, and the dual-head drive component in the drive assembly 10. Each air pump assembly 66 is also connected to a relay switch 654, a pressure sensor 664, and a pressure relief solenoid valve 665, so that different components can be inflated and deflated by different air pump assemblies 66 to assist each component in completing its corresponding work.

[0098] When a massage is needed, the air pump assembly 66 inside the main control box 6 can be controlled to inflate the drive assembly 10 through the air supply pipe 9. The gas delivered by the air supply pipe 9 is sent into the housing 101 through the air inlet 1016 and discharged through the air outlet 1015. This drives the drive fan blade 1013 to rotate inside the housing 101, causing the rotating column 1011 to rotate accordingly. This, in turn, drives the rotating rod 102 to rotate. The rotating rod 102 will drive the shoulder massage assembly 7 and the acupoint massage assembly 8 to massage the patient's shoulders and temples through the first and second transmission components, respectively. The massage intensity is determined by the air pressure of the air pump assembly 66.

[0099] During shoulder massage, the rotating rod 102 drives the first bevel gear 103 to rotate, which in turn drives the first rotating shaft 73 to rotate through its meshing with the second bevel gear 72. The first rotating shaft 73 drives the rotating block 74 to rotate within the mounting housing 71, thereby driving the first massage head 75 to massage the patient's shoulder. At the same time, a rotating seat 77 is provided on the rotating block 74 and is slidably connected to the first rotating shaft 73. A spring is sleeved on the rotating block 74 between the rotating block 74 and the mounting housing 71. The rotating block 74 can extend and retract during rotation, so that the first massage head 75 can adaptively extend and retract according to the patient's shoulder during the massage, improving the comfort of the massage.

[0100] During the temple massage, the rotating rod 102 drives the first pulley 104 to rotate, which in turn drives the second pulley 85 to rotate via the belt 105. The second pulley 85 drives the eccentric wheel 83 to rotate via the second rotating shaft 84. The eccentric wheel 83, through its rotational connection with the middle of the swing rod 81, drives the swing rod 81 to swing back and forth in the movable groove 221, thereby driving the second massage head 82 connected to the upper end of the swing rod 81 to massage the temples of the patient's head, so as to eliminate fatigue, reduce breathing rate, improve concentration for subsequent breath-holding, and ensure the effect of breath-holding.
