Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a fully automatic medical auxiliary breath-holding device. Background Art

[0002] As the technology of medical radiological examination equipment such as medical X-ray machines, CT and MR becomes more and more mature, radiological examination has become an increasingly common clinical examination, playing an important role in the initial screening, positioning and characterization of diseases.

[0003] During current CT scans, some inspection areas require patients to hold their breath during the inspection (e.g., coronary artery CT scans, chest and abdominal enhanced CT scans, etc.). If the patient does not cooperate with breathing well, the images produced by the CT scan will be blurred due to the movement caused by the patient's breathing, making it impossible for the diagnosing doctor to carefully observe the inspection images, and ultimately leading to CT scan failure. Secondly, during this inspection, the patient also needs to be injected with iodine contrast agent. If the inspection fails due to poor breathing coordination, the repeated overdose of iodine contrast agent may also cause liver and kidney damage to the patient. Thirdly, unnecessary radiation damage should be avoided as much as possible during CT inspections. The best protection method is to cooperate with the doctor and technician's inspection requirements during the inspection, cooperate with breathing well, and try to avoid repeated CT inspections in a short period of time. Therefore, there is a need for a device that can assist patients in holding their breath in conjunction with CT inspection equipment.

[0004] A Chinese patent with publication number CN221356866U discloses a breath-holding auxiliary device for abdominal magnetic resonance examination, including a chest airbag, an abdominal airbag, a support pad, a connecting tube, a connecting rope, a No. 1 Velcro, a No. 2 Velcro, an air nozzle, a sealing plug, a sponge and silicone. A connecting tube is fixedly connected between the chest airbag and the abdominal airbag, and a connecting rope is fixedly connected between the abdominal airbag and the support pad. Both sides of the chest airbag are equipped with a No. 1 Velcro, both sides of the abdominal airbag are equipped with a No. 2 Velcro, and air nozzles are installed on the surfaces of the chest airbag and the abdominal airbag, and a sealing plug is provided on the top of the air nozzle. In actual use, by arranging the chest airbag, the abdominal airbag, the support pad, the connecting tube, the connecting rope, the No. 1 Velcro, the No. 2 Velcro, the air nozzle, the sealing plug, the sponge and the silicone, the patient can mostly switch to abdominal breathing and hold his breath for a long time, thereby maximizing the imaging quality.

[0005] Chinese patent publication number CN212281374U discloses a breath-holding assist device, comprising: a control module that controls the operation of the breath-holding assist device; a main body having a receiving slot for accommodating the patient's head; a nasal breath-holding module that is in communication with the control module and operates under the control of the control module to seal the patient's nose; and a mouth breath-holding module that is in communication with the control module and operates under the control of the control module to seal the patient's mouth. Compared to the prior art, the breath-holding assist device provided by the present invention uses the receiving slot to fix the patient's head while the patient is undergoing a radiological examination, which is beneficial for performing radiological examinations on the patient. At the same time, the nasal breath-holding module and the mouth breath-holding module cooperate to seal the patient's nose and mouth, respectively, preventing the patient from breathing through their nose and mouth and automatically entering a breath-holding state, thereby improving the efficiency of radiological examinations.

[0006] Medical breath-holding assist devices such as the above-mentioned ones have simple functions, low automation and scope of application, lack the ability to fix the patient's head, and are easily affected by the patient's head movement. For some patients who are unable to hold their breath independently, elderly patients, deaf-mute patients and other patients with poor cooperation, the movement caused by the patient's breathing is likely to produce a blurring effect, resulting in the diagnostic doctor being unable to carefully observe the examination image, resulting in a low examination success rate and low examination image quality, and the need for repeated examinations. It is relatively time-consuming and labor-intensive, and cannot eliminate the patient's nervousness during the examination, which is likely to affect the patient's breath-holding time and breath-holding effect. Summary of the Invention

[0076] Example 1

[0077] like Figure 1-24 As shown, the present invention provides a fully automatic medical auxiliary breath-holding device, including an inflatable pressurized abdominal belt 1 placed on the patient's abdomen. The inflatable pressurized abdominal belt 1 can be used alone to compress and pressurize patients who are too old or have poor exhalation conditions to remind the patient to hold his breath. At the same time, the inflatable pressurized abdominal belt 1 can also be used to limit the movement of the patient's abdominal wall, thereby minimizing respiratory motion artifacts caused by poor respiratory coordination and improving image quality. There is also an inflatable pressurized nose clip mechanism 4 for squeezing the patient's nose and lips. Through the setting of the inflatable pressurized nose clip mechanism 4, the patient's nose and mouth can be blocked at the same time, avoiding the patient from breathing with his mouth open while holding his breath, thereby improving The cooperation of the patient examination also includes a head support and fixing seat 2, which is a U-shaped groove structure and has a protective pad 21 inside, which is used to support and fix the patient's head to avoid image blur and jagged artifacts caused by head rotation during the patient examination, thereby improving image quality. The inflatable pressurized nose clip mechanism 4 is arranged on the head support and fixing seat 2, and the main control box 6 is provided with three groups of air pump components 66. The three groups of air pump components 66 are respectively connected to the inflatable pressurized abdominal belt 1 and the inflatable pressurized nose clip mechanism 4 through three air pipes 9. The main control box 6 is wirelessly connected to the remote control box 5. The mutual cooperation of the remote control box 5 and the main control box 6 can improve the degree of automation of the device.

[0078] Specifically, a control component is further provided in the main control box 6 , and the control component is electrically connected to the air pump component 66 for controlling the opening or closing of the air pump component 66 to improve the convenience of its control.

[0079] Specifically, the air pump assembly 66 includes an air pump 661, which adopts a small DC diaphragm air pump. The output end of the air pump 661 is connected to a four-way connector 662, and the four-way connector 662 is connected to the air supply pipe 9 through a fourth connecting pipe 663. The pressure relief solenoid valve 665 and the pressure sensor 664 are connected to the four-way connector 662. The air pump 661, the pressure relief solenoid valve 665 and the pressure sensor 664 are all electrically connected to the control component, and then the air pump 661 can be used to inflate and deflate the inflatable pressurized abdominal belt 1 and the inflatable pressurized nose clip mechanism 4. For patients who are too old or have poor breathing conditions, they can be used separately. The use of the pneumatic pressurized abdominal belt 1 to apply pressure can remind the patient to hold his breath. At the same time, the pneumatic pressurized abdominal belt 1 can be used to limit the movement of the patient's chest wall, abdominal wall, and diaphragm, thereby minimizing the respiratory motion artifacts caused by poor respiratory coordination, improving image quality, and meeting diagnostic requirements. At the same time, the use of the pneumatic pressurized nose clip mechanism 4 to apply pressure directly replaces the patient's family members pinching the patient's nose to assist in holding their breath, thereby avoiding radiation damage to the patient's family members. For patients with chest and abdominal injuries or who are not suitable for the use of a pressurized pneumatic pressurized abdominal belt, it is recommended to only use the pneumatic pressurized nose clip mechanism 4.

[0080] Specifically, a compression airbag 11 is provided in the middle of the inner side of the inflatable pressurized abdominal belt 1, and the compression airbag 11 is provided with a first connecting tube 12. The first connecting tube 12 is connected to the air pump assembly 66 through the air supply pipe 9, and then the air can be inflated and discharged into the compression airbag 11 through the air pump assembly 66, so as to remind the patient to hold his breath by pressurizing the compression airbag 11, improve the patient's cooperation, and ensure the clarity and success rate of the image in the CT examination. A plurality of airbag blocks 13 are provided on the compression airbag 11, and connectors 14 are respectively provided at both ends of the inflatable pressurized abdominal belt 1. The connectors 14 are respectively connected to the two ends of the inflatable pressurized abdominal belt 1 by elastic belts to adapt to patients of different fat and thin sizes. The connectors 14 can be Velcro that stand on each other, or they can be buckles that are clamped to each other, so as to facilitate fixing the inflatable pressurized abdominal belt 1 on the patient.

[0081] Specifically, the inflatable pressurized nose clip mechanism 4 is connected to the head support fixing seat 2 through the mask 3, and the mask 3 is connected to the top of the head support fixing seat 2 through the strap 31. The inflatable pressurized nose clip mechanism 4 includes a nose clip 41, which is a U-shaped elastic clip structure, and a clamping groove 32 is opened at the top of the mask 3. The nose clip 41 is connected to the clamping groove 32 at the top of the mask 3 through a support member 43, so that the patient's nose is exposed from the clamping groove 32 and clamped by the nose clip 41. The nose clip airbag 42 adopts a small airbag and is set at the opening of the nose clip 41 to assist the nose clip 41 in completing the clamping and breath-holding work of the patient's nose. The nose clip airbag 42 can also play a buffering role to alleviate the discomfort caused by the clamping of the nose clip 41. The nose clip airbag 42 top The nose clip 41 is connected to the vent seat 44 through the second connecting tube 442, and the vent seat 44 is connected to the air supply pipe 9. The air supply pipe 9 is used to fill and discharge gas into the nose clip airbag 42 to realize its pressurized clamping or decompressed release function. The vent seat 44 is connected to the compression airbag 33 on the inside of the mask 3 through the third connecting tube 441. The compression airbag 33 is used to seal the patient's mouth to prevent the patient from breathing with his mouth open when holding his breath. At the same time, the nose clip 41, the nose clip airbag 42 and the compression airbag 33 on the mask 3 can be used to avoid the adverse effects caused by the patient pinching his nose by himself or the family members reaching into the magnet hole to assist in pinching the nose, thereby improving the patient's examination comfort and cooperation, reducing the burden on family members accompanying the examination, and further improving the effect of magnetic resonance chest and abdominal examination.

[0082] Specifically, a first display screen 61 is provided on the top of the main control box 6 for displaying the working status of each component in the main control box 6. It can detect and display the respiratory wave, the pressure of the pneumatic compression abdominal belt 1 and the pneumatic compression nose clip mechanism 4 in real time. The respiratory wave and pressure display are provided by signals provided by the pressure sensor 664. A first emergency stop switch 63 for controlling the air pump assembly 66 and three air pump pressure indicator lights 62 for displaying the air pump pressure are provided on the outside of the first display screen 61. The three air pump pressure indicator lights 62 are respectively distinguished by red, green and blue. 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 is known which pressure sensor has the problem of too high or too low air pressure. A knob-type pressure adjustment switch is provided on the surface of the main control box. Since each patient has a different tolerance to the pressure of the abdominal belt and nose clip balloon, the CT technician or nurse needs to set the pressure threshold in advance during training. The knob-type pressure adjustment switch is first adjusted to adjust the pressure. 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 so as to learn voice commands through the interface.

[0085] Specific implementation cases:

[0086] Before the CT scan, the CT device will issue an inhalation instruction: "Please inhale, hold your breath!", and after the scan is completed, it will issue an exhalation instruction: "You can breathe!". The present invention uses the voice recognition chip 651 and the onboard high-gain microphone 67 to recognize the above two groups of sounds, and sends a start instruction to the power supply circuit 655 through the main control chip 652. The relay switch 654 is energized and closed, and the air pump assembly 66 starts to pump air. The pressure sensor 664 is used to inflate the inflatable pressure belt 1 and the nose clip airbag 42 respectively. The inflation process should be controlled within 5 seconds. During this period, when the pressure sensor 664 senses that the pressure has reached the working set value, the main control chip 652 immediately issues an instruction to stop pumping, the relay switch 654 is powered off and stops working, and the CT scan starts immediately. After the inspection and scan are completed, the CT machine issues an exhalation instruction: "You can breathe!" The voice recognition chip 651 and the onboard high-gain microphone 67 receive the sound and recognize it. The main control chip 652 sends a start instruction to the control power supply circuit 655, and the pressure relief solenoid valve 665 deflates the inflatable pressure abdominal belt 1 and the nose clip airbag 42. The deflation process should be controlled within 4 seconds.

[0087] During the entire 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 is synchronously displayed on the second display screen 51 of the Bluetooth WIFI remote control box 5 through the Bluetooth WIFI mode. The CT examination technician can select the start time of the CT scan in real time by observing the respiratory wave displayed on the second display screen 51 of the Bluetooth WIFI remote control box 5. Generally, the scan will be started when the patient's respiratory wave is stable, that is, when the patient starts to hold his breath.

[0088] It is worth noting that the use of the entire device requires operational explanations and strict training before patient 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 compression belt 1 and the nose clip airbag 42, the CT technician or nurse needs to set the pressure threshold in advance during training. First, adjust the pressure sensor 664 by adjusting the knob, and set the optimal breath-holding pressure value for the first patient according to the patient's breath-holding effect. The purpose is to enable the patient to hold his breath more safely and effectively to prevent excessive pressure from causing harm to the patient. In extreme cases, if the inflation pressure exceeds the set value, or the pressure relief solenoid valve 665 does not work properly for a long time, the CT examination technician will immediately observe the alarm on the second display screen 51 on the Bluetooth WIFI remote control box 5, press the emergency stop button, and remotely disconnect the relay switch 654 to stop inflating the inflatable compression belt 1 and the nose clip airbag 42. The technician should immediately rush to the patient's side to disconnect the inflatable compression nose clip mechanism 4 and the inflatable compression belt 1.

[0090] Example 2

[0091] like Figure 1 , Figure 3-6 , Figure 14-18 and Figure 25 As shown, the head support base 2 is also provided with a massage mechanism, which is connected to the main control box 6 via an air pipe 9. The massage mechanism includes a shoulder massage component 7, which is arranged at the front bottom of the head support base 2 and is used to massage the patient's shoulders. The shoulder massage component 7 is connected to a drive component 10 located within the head support base 2, and an acupoint massage component 8, which is arranged at the upper inner end of the head support base 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 pipe 9. The drive component 10 drives 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, which can eliminate the patient's tension, stimulate the brain, eliminate mental fatigue, reduce breathing rate, improve concentration during subsequent breath-holding, and effectively extend the breath-holding time and breath-holding effect.

[0092] Specifically, the driving assembly 10 includes a double-headed driving member, which is arranged on the front side of the head support fixing seat 2 and is connected to the air pump assembly 66 through the air supply pipe 9. The double-headed driving member is connected to a rotating rod 102. The first transmission member is arranged in the middle of the rotating rod 102 and is connected to the shoulder massage assembly 7. The first transmission member is composed of a first bevel gear 103 and a second bevel gear 72 that are meshed with each other. The rotating rod 102 drives the first bevel gear to rotate, and then drives the shoulder massage assembly 7 through the second bevel gear 72 to perform shoulder massage. The second transmission member is arranged at the end of the rotating rod 102 and is connected to the acupoint massage assembly 8. The second transmission member is composed of a first pulley 104 and a second pulley 85 that are connected by the power of 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. The shoulder massage assembly 7 and the acupoint massage assembly 8 can be driven by the driving assembly 10 to massage the patient's shoulders and temples to eliminate the patient's tension.

[0093] Specifically, the shoulder massage component 7 includes a mounting shell 71, which is embedded in the front bottom of the head support fixing seat 2. The inner side of the mounting shell 71 is rotatably connected to the first rotating shaft 73. The first rotating shaft 73 is connected to the second bevel gear 72 of the first transmission member to drive the shoulder massage component 7 to complete the shoulder massage work. The rotating block 74 is set in the mounting shell 71. The rotating block 74 is connected to the first rotating shaft 73 through the rotating seat 77. The first rotating shaft 73 is slidably connected in the rotating seat 77. There are at least three first massage heads 75 in a circular array on the outer end surface of the rotating block 74, and the buffer member 76 can be a spring, which is sleeved on the first rotating shaft 73 and abuts between the preset rotating blocks 74 of the mounting shell 71, and is used to realize the extension and retraction of the first massage head 75. Then, in the process of the first rotating shaft 73 driving the first massage head 75 on the rotating block 74 to massage the patient's shoulders, the extension and retraction of the first rotating shaft 73 in the rotating seat 77, combined with the elastic effect of the buffer member 76, allows the rotating block 74 to extend and retract in the mounting shell 71, and then the first massage head 75 can adaptively extend and retract during the massage process, thereby improving the comfort of the patient.

[0094] Specifically, the acupoint massage component 8 includes an eccentric wheel 83, which is arranged at the upper end of the inner side of the head support fixed seat 2. A fixed plate 22 is provided on both sides of the head support fixed seat 2. A movable groove 221 is provided on the upper side of the fixed plate 22. The eccentric wheel 83 is arranged in the movable groove 221. The eccentric wheel 83 is connected to the second pulley 85 of the second transmission member through the second rotating shaft 84. The swing rod 81 is connected to the edge of the eccentric wheel 83 in the middle. The upper end of the swing rod 81 is connected to the second massage head 82 located in the head support fixed seat 2. The second massage head 82 is located on the outer side of the top of the fixed plate 22. The swing rod The lower end of 81 is connected with a connecting rod 86, which assists the swing rod 81 to make reciprocating motion. During the temple massage process, the second transmission member drives the second rotating shaft 84 to rotate through the second pulley 85, and then drives the eccentric wheel 83 to rotate. By utilizing the rotational connection relationship between the eccentric wheel 83 and the middle part of the swing rod 81, the toggle rod 81 can be driven to swing in the movable groove 221, thereby increasing the swinging of the swing rod 81 to make the second massage head 82 to make reciprocating motion. Through this reciprocating motion, the patient's temple can be massaged to relax the patient's head, eliminate fatigue, improve the concentration of subsequent breath holding, and enhance the breath holding effect.

[0095] Specifically, the double-head drive member includes a housing 101, which is connected to the front bottom of the head support fixing seat 2 through a connecting block. A rotating column 1011 is connected to the housing 101 through 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 the air pipe 9, and the driving blades 1013 are arranged in a circular array on the outer arc surface of the rotating column 1011. The outer ends of the driving blades 1013 do not conflict with the inner wall of the housing 101. When massage is required, The gas can be injected into the housing 101 from the air inlet 1016 through the air pump assembly 66 via the air pipe 9, and then discharged from the air outlet 1015 to form an airflow, which can be used to blow the driving blades 1013 to move. The driving blades 1013 in the annular array on the rotating column 1011 can drive the rotating column 1011 to rotate in the housing 101, and then drive the rotating rod 102 to rotate. The rotating rod 102 drives the shoulder massage component 7 and the acupoint massage component 8 to perform massage through the first transmission member and the second transmission member respectively.

[0096] Furthermore, the driving fan blades 1013 can be configured as blades with a certain curvature, and the air inlet 1015 can be directly facing the arc-shaped bending position to reduce the resistance required for driving and enhance its expected effect.

[0097] It should be noted that in the present invention, three groups of air pump assemblies 66 are provided, each of which is connected to three air supply pipes 9. Each air supply pipe 9 is respectively 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 double-headed driving member in the driving assembly 10, and each air pump assembly 66 is respectively 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 through different air pump assemblies 66 to assist each component in completing the corresponding work.

[0098] When massage is needed, the main control box 6 can be used to control the air pump assembly 66 therein to inflate the drive assembly 10 through the air pipe 9, and the gas transported from the air pipe 9 is sent into the casing 101 through the air inlet 1016 and discharged through the air outlet 1015, thereby driving the drive fan blades 1013 to rotate in the casing 101, causing the rotating column 1011 to rotate accordingly, and then driving the rotating rod 102 to rotate. The rotating rod 102 will drive the shoulder massage assembly 7 and the acupoint massage assembly 8 through the first transmission member and the second transmission member to massage the patient's shoulders and temples respectively, and the massage intensity is determined by the air pressure of the air pump assembly 66.

[0099] During the shoulder massage process, the first bevel gear 103 is driven to rotate by the rotating rod 102, and then the first rotating shaft 73 is driven to rotate by utilizing the meshing relationship with the second bevel gear 72. The first rotating shaft 73 drives the rotating block 74 to rotate in the mounting shell 71, and then drives the first massage head 75 to massage the patient's shoulders. At the same time, a rotating seat 77 slidingly connected to the first rotating shaft 73 is provided on the rotating block 74, and a spring located between the rotating block 74 and the mounting shell 71 is sleeved on it. The rotating block 74 can be extended and retracted during the rotation process, so that the first massage head 75 can adaptively extend and retract according to the patient's shoulders during the massage process, thereby improving the comfort of the massage.

[0100] During the temple massage process, the first pulley 104 is driven to rotate by the rotating rod 102, and then the second pulley 85 is driven to rotate by the belt 105. The second pulley 85 drives the eccentric wheel 83 to rotate through the second rotating shaft 84. The eccentric wheel 83 utilizes the rotational connection relationship with the middle part of the swing rod 81 to drive the swing rod 81 to swing back and forth in the movable groove 221, and then drives the second massage head 82 connected to the upper end of the swing rod 81 to massage the patient's temples, so as to eliminate fatigue, reduce breathing frequency, improve concentration in subsequent breath holding, and ensure the breath holding effect.
