Description

Technical Field

[0001] The embodiments of the present application relate to the field of medical technology, and in particular to an automatic pressure-relieving endotracheal intubation device, a cuff inflation method, a computer-readable storage medium, and a control device. Background Art

[0002] The endotracheal cuff is a crucial component of endotracheal intubation. After intubation, the cuff is inflated to isolate the artificial airway from the oropharynx. Low cuff pressure can cause ventilation leaks, insufficient tidal volumes, aspiration of airway secretions or digestive fluids, and failure of lung isolation, making thoracic surgery impossible. High cuff pressure, on the other hand, can compress the patient's tracheal wall, blocking the local mucosal blood supply and leading to critical conditions such as mucosal necrosis, tracheal stenosis, or tracheal laceration.

[0003] Currently, clinical practice involves manually measuring and adjusting cuff pressure every few hours using a manometer. However, in practice, rapid inflation of the emergency intubation cuff, the use of nitrous oxide during surgery, and endotracheal tube displacement can cause elevated cuff pressures. Changes in head and neck position and cuff leaks can also lead to abnormally low pressures. Traditional cuff monitoring methods cannot guarantee rapid and consistent achievement of safe cuff pressures during rapid sequence intubation. Cuff pressures below 20 cmH2O are known to cause leaks, while those above 40 cmH2O for more than 15 minutes can cause tracheal mucosal ischemia and damage. Studies have shown that >50-80% of patients experience cuff pressures exceeding 40 cmH2O immediately after intubation in the emergency, ICU, and operating room settings. Therefore, most current endotracheal intubations require re-adjustment of cuff pressure to ensure clinical safety. Furthermore, real-time monitoring of cuff pressure changes during long-term intubation is currently unavailable, and cuff pressure management is highly dependent on the work practices of individual medical centers, potentially overlooking critical conditions and posing safety risks.

[0004] Currently, related patents still have operational issues or practicality issues. For example, external pressure-indicating devices or pressure-measuring and inflation devices are cumbersome to operate and have high equipment and labor costs; or pressure reading and adjustment are slow, which is not conducive to rapid operation during rescue intubation. The present invention has an automatic decompression device during rapid inflation, which is suitable for rapid operation during rescue endotracheal intubation. It also has a constant pressure monitoring function, which not only prevents high pressure in the cuff from damaging the tracheal mucosa, but also avoids the risk of airway secretion aspiration due to low pressure.

[0041] Compared with the prior art, the present invention includes at least the following beneficial effects: the automatic pressure relief endotracheal intubation device provided in the embodiment of the present application includes an endotracheal intubation tube, an air barrier cuff, a connecting tube and an automatic pressure relief protector, wherein the automatic pressure relief protector includes: an air injection tube, a fixing seat, a reset member, a sealing member, a first groove and a second groove. During use, one end of the air injection tube is used to be connected to the connecting tube. When the end of the air injection tube closer to the fixing seat is connected to the connecting tube, the medical staff can inject gas into the air injection tube at the end of the air injection tube closer to the second groove through a syringe. The injected gas will push the sealing member and overcome the reset force of the reset member, so that the sealing member is in the first groove. In this case, the air injection tube is connected, and the outside External gas can be supplied to the connecting tube through the first groove and then injected into the air barrier cuff through the connecting tube. The pressure in the air barrier cuff is equivalent to the pressure in the air injection tube. As the amount of gas injected increases, the pressure in the air barrier cuff increases. The combination of the larger pressure and the restoring force of the reset member will push the seal to move. When the pressure in the air barrier cuff is large, the pressure can overcome the force of gas injection, thereby pushing the seal between the first groove and the second groove. In this case, it means that the gas injection pressure is relatively moderate. Professional medical personnel can stop injecting gas in this case. Continuing to inject gas during inexperienced or emergency intubation will further increase the pressure in the air barrier cuff. In this case, the seal will be in the second groove. (The second groove is a large groove with a long distance), the insufflation tube is opened again, and the excessive pressure of the cuff will be automatically released through the second groove. Based on this, the automatic pressure relief tracheal intubation device provided by the embodiment of the present application can make medical staff not worry about high-pressure damage and low-pressure leakage of patients, and can automatically adjust the cuff pressure to a safe range, which can improve efficiency and be safer. Furthermore, if special patients have special problems with their airways and lungs and need high cuff pressure, when higher pressure gas needs to be injected into the air barrier cuff, the insufflation tube can be rotated to make the first groove section (small groove) close to the air hole. At this time, it is in a high-pressure state, and medical staff can slowly inject gas into the insufflation tube through the air hole according to the pressure indication scale. In this case, the slowly injected gas can push the seal to move to the first groove, and the gas injection tube is always in a conducting state, so that a pressure higher than 35mmH2O is slowly injected into the cuff. This high-pressure mode should be operated by professionals according to special conditions. Based on this, the automatic pressure relief endotracheal intubation device can be applied to special patients with high pressure needs; after anesthesia intubation, it can be adjusted to a constant pressure mode, and the gas injection tube is rotated to make it 90 degrees or vertical to the punch hole and the gas injection hole. At this time, because there is a sealing gasket between the base and the shield where the gas injection tube is located, the gas injection hole and the gas injection tube are both sealed. Based on this, the automatic pressure relief endotracheal intubation device can maintain constant pressure without air leakage in the case of long surgery or long-term tube wearing in the ICU.

DETAILED DESCRIPTION

[0054] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0055] like Figures 1 to 6 As shown, according to the first aspect of the embodiment of the present application, an automatic pressure relief tracheal intubation device is proposed, comprising: a tracheal intubation tube 1; an air barrier cuff 2, which is arranged on the tracheal intubation tube 1; a connecting tube 22, one end of which is connected to the air barrier cuff 2; an automatic pressure relief protector 3, which is connected to the other end of the connecting tube 22; wherein the automatic pressure relief protector 3 comprises: an air injection tube, a fixing seat 34, a reset member 35, a sealing member 36, a first groove 37 and a second groove 38, the first groove 37 and the second groove 38 are opened on the inner wall of the air injection tube , and the first groove 37 and the second groove 38 are arranged at intervals, the fixing seat 34 is connected to the inner wall of the gas injection pipe, and is located at one end of the first groove 37 away from the second groove 38. One end of the reset member 35 is connected to the fixing seat 34, and the sealing member 36 is connected to the reset member 35. When the reset member 35 abuts against the inner wall of the gas injection pipe, the gas injection pipe is sealed. When the reset member 35 is in the second groove 38 or in the second groove 38, the gas injection pipe is conducted. There is a sealing gasket between the rotating seat where the gas injection pipe is located and the shield, and the opening is at the air hole and the gas injection hole.

[0056] The automatic pressure relief tracheal intubation device provided in the embodiment of the present application includes a tracheal intubation tube 1, an air barrier cuff 2, a connecting tube 22 and an automatic pressure relief protector 3, wherein the automatic pressure relief protector 3 includes: an air injection tube, a fixing seat 34, a reset member 35, a sealing member 36, a first groove 37 and a second groove 38. During use, one end of the air injection tube is used to connect to the connecting tube 22. When the end of the air injection tube closer to the fixing seat 34 is connected to the connecting tube 22, the medical staff can inject gas into the air injection tube at the end of the air injection tube closer to the second groove 38 through a syringe. The injected gas will push the sealing member 36 and overcome the reset force of the reset member 35, so that the sealing member 36 is in a In the first groove 37, in this case, the gas injection tube is conducted, and external gas can be supplied to the connecting tube 22 through the first groove 37, and then injected into the air barrier cuff 2 through the connecting tube 22. The pressure in the air barrier cuff 2 is equivalent to the pressure in the gas injection tube. As the amount of gas injected increases, the pressure in the air barrier cuff 2 increases. The combination of the larger pressure and the reset force of the reset member 35 will push the sealing member 36 to move. When the pressure in the air barrier cuff 2 is larger, the pressure can overcome the force of gas injection, thereby pushing the sealing member 36 between the first groove 37 and the second groove 38. In this case, it shows that the gas injection pressure is relatively moderate. Experienced medical personnel in this case The gas injection can be stopped. For inexperienced medical staff or emergency rapid intubation, continuing to inject gas will further increase the pressure in the air barrier cuff 2. In this case, the pressure can overcome the force of gas injection, and the seal 36 will be in the second groove 38 (the second groove is a large groove with a long distance). The gas injection tube is connected again, and the excessive pressure in the cuff will be automatically released through the second groove 38. Based on this, the automatic pressure relief tracheal intubation device provided by the embodiment of the present application can enable medical staff to not worry about high-pressure damage and low-pressure leakage of patients, and can automatically adjust the pressure of the cuff 2 to a safe range, which can improve efficiency and be safer. Furthermore, if special patients have airway and lung problems, When high cuff pressure is required and higher pressure gas needs to be injected into the air barrier cuff 2, the rotary handle 32 on the insufflation pipe can be rotated to make the first groove 37 close to the insufflation hole 4. At this time, the high pressure state is reached and the medical staff can slowly inject gas into the insufflation pipe through the insufflation hole 4 according to the pressure indicator scale. In this case, the slowly injected gas can push the sealing member 36 to move to the first groove 37. The insufflation pipe is always in a conductive state, so that a pressure higher than 35 mmH2O is slowly injected into the cuff 2. This high pressure mode should be operated by professionals according to the special conditions of the patient. Based on this, the automatic pressure relief endotracheal intubation device can be applied to special patients with high pressure needs.After anesthesia and intubation, the device can be adjusted to constant pressure mode by rotating the rotary handle 32 of the insufflation tube so that it is 90 degrees or perpendicular to the pumping hole 4 and the insufflation hole. At this time, due to the sealing gasket between the base of the insufflation tube and the protective cover, the insufflation hole 33 and the insufflation tube are both sealed. Based on this, the automatic pressure relief endotracheal intubation device can maintain constant pressure without air leakage during long surgeries or long-term intubation in the ICU.

[0057] The automatic pressure-relieving endotracheal intubation device provided in the embodiments of this application can be a single, integral structure, maintaining the original endotracheal tube material, ensuring safe insertion into the human body. It is easy to operate, and the rapid inflation process is highly consistent with the traditional endotracheal intubation process, ensuring the safety of emergency operations. The monitoring process is intuitive, objective, and accurately quantified, and the cuff pressure adjustment process is simple, requiring no additional manual operation compared to existing technologies. It also requires no external equipment, resulting in low cost.

[0058] It is understood that the length of the second groove 38 may be greater than that of the first groove 37, and the positions of the first and second grooves 37, 38 may be determined based on the positions of the sealing member 36 at different pressures within the air barrier cuff 2. For example, when the pressure within the air barrier cuff 2 is lower than 25 cmH2O, the sealing member 36 is located within the first groove 37; when the pressure within the air barrier cuff 2 is greater than 25 cmH2O but less than 35 cmH2O, the sealing member 36 is located between the first and second grooves 37, 38; and when the pressure within the air barrier cuff 2 is greater than 35 cmH2O, the sealing member 36 is located within the second groove 38.

[0059] It can be understood that the first groove 37 and the second groove 38 are relatively fixed and are used for injecting gas and releasing pressure higher than 35 cmH2O. When in a high-pressure state, it is used for injecting gas. The rotating handle 32 on the gas injection pipe can be rotated to make the first groove 37 section close to the air hole 4. At this time, it is a high-pressure state, and the pressure in the air isolation cuff 2 will be displayed on the scale in real time.

[0060] In a feasible embodiment, the automatic pressure relief protector 3 also includes: a protective cover 31, an air injection pipe is rotatably arranged in the protective cover 31, and both ends of the air injection pipe are in contact with the protective cover 31, and the remaining part has a sealing gasket; an air hole 4, which is opened on the protective cover 31; an air injection hole, which is opened on the protective cover 31 and connected to the connecting pipe 22.

[0061] In this technical solution, the automatic pressure relief protector 3 can also include a protective cover 31, an air pumping hole 4 and an air injection hole. With such an arrangement, on the one hand, the three connection states of the air injection tube and the air isolation cuff 2 can be switched conveniently by rotating the air injection tube relative to the protective cover 31; on the other hand, the sealing connection between the connecting tube 22 and the automatic pressure relief protector 3 is facilitated.

[0062] In some examples, the gas injection pipe is a flat cylinder with a gas injection pipe formed in the middle, and the gas injection pipe fits tightly with the shield 31. When the gas injection pipe is turned to both ends, the automatic pressure relief protector 3 is working, and when it is turned to other places, the automatic pressure relief protector 3 is constant pressure.

[0063] In some examples, the shield 31 may be an inner wall air barrier, which is a flat cylinder that is hollow except for the air injection holes at both ends.

[0064] In some examples, the shield 31 is made of a transparent material, which makes it easier for medical personnel to observe the insufflation tube, especially the position of the seal 36 .

[0065] In a feasible implementation manner, the automatic pressure relief protector 3 further includes: a rotating handle 32 connected to the gas injection pipe, and used to drive the gas injection pipe to rotate.

[0066] In this technical solution, the automatic pressure relief protector 3 may further include a rotating handle 32 , and the arrangement of the rotating handle 32 facilitates the rotation of the gas injection pipe.

[0067] In a feasible embodiment, the end of the gas injection pipe close to the second groove 38 is the self-pressure relief injection end 311, and the end of the gas injection pipe close to the fixed seat 34 is the injection end 33; when the self-pressure relief injection end 311 of the gas injection pipe is connected to the air hole 4, the high-pressure injection end 33 is connected to the gas injection hole; when the injection end 33 of the gas injection pipe is connected to the air hole 4, the self-pressure relief injection end 311 is connected to the gas injection hole.

[0068] In this technical solution, the gas injection pipe may further include a self-decompression injection end 311 and an injection end 33 .

[0069] like Figure 2 As shown, when the self-depressurizing injection end 311 is connected to the inflation hole 4, the automatic pressure relief protector 3 is in the automatic pressure relief mode, and the injected gas enters the air isolation cuff 2 from the first ventilation groove 37. After the inflation is completed, the pressure of the air isolation cuff 2 and the elastic force of the reset member 35 cause the reset member 35 to stretch. When the pressure of the air isolation cuff 2 is lower than 25 cmH2O, the sealing member 36 is in the low pressure indication area of ​​the air injection tube, indicating that the pressure of the air isolation cuff 2 is low at this time, prompting the doctor to continue inflation; when the cuff pressure is between 25 cm and 35 cmH2O, the sealing member 36 is in the normal indication area; when the cuff pressure is higher than 35 cmH2O, the sealing member 36 passes through the second pressure relief groove 38, and the air isolation cuff 2 can quickly relieve the pressure to the normal pressure area of ​​35 cmH2O through the second groove 38. After the pressure relief, the pressure of the air isolation cuff 2 stabilizes at this level.

[0070] In some examples, the restoring element 35 is a spring calibrated according to Hooke's law: F = k·Δx, where k is a constant and is the stiffness coefficient of the object, Δx is the deformation (elastic deformation), and F is the elastic force.

[0071] It is understandable that the outer wall of the insufflation tube can be coated with different colors, and the color and scale area on the outer wall of each process tube can display the pressure in real time and prompt the doctor.

[0072] like Figure 2 As shown, the reset member 35 of the automatic pressure relief protector 3 is calibrated by Hooke's law (F=K·X) and the deformation is proportional to the cuff pressure. The pressure of the air isolation cuff 2 is displayed correspondingly on the outer wall by a first scale mark, a second scale mark 39 and three color pressure indicators of low, medium and high.

[0073] like Figure 3 As shown, when a higher cuff pressure (higher than 35 cmH2O) is required under special circumstances, the handle 32 can be rotated to connect the high-pressure injection end 33 of the gas injection tube to the pumping hole 4. At this time, the air-isolating cuff 2 will not be deflated when air is pumped through the pumping hole 4. The doctor can pump air as needed within the safe pressure range, and the air-isolating cuff 2 can display the pressure value in real time through the second scale mark 39.

[0074] like Figure 3 As shown, when the pressure of the air barrier cuff 2 is within a reasonable range, due to the long operation time or the ICU patient wearing a tube for a long time, the doctor adjusts the insufflation tube to 90 degrees to prevent the air barrier cuff 2 from leaking due to long-term pressure.

[0075] It can be understood that the automatic pressure relief protector 3 provided in the embodiment of the present application is applicable to single-lumen endotracheal tube 1, double-lumen endotracheal tube 1, laryngeal mask and various artificial airway devices with similar cuff pressure design.

[0076] In a feasible embodiment, a first color mark and a second color mark are provided on the rotating handle 32. The first color mark is used to point to the self-decompression injection end 311, and the second color mark is used to point to the high-pressure injection end 33. The first color mark and the second color mark are different.

[0077] It is understandable that the first color identification may be red, and the second color identification may be green.

[0078] In this technical solution, a first color mark and a second color mark are set on the rotating handle 32. This setting makes it easy for medical staff to clearly know the conduction status of the gas injection tube and the connecting tube 22, and can avoid incorrect operations.

[0079] In a feasible embodiment, the automatic pressure relief protector 3 also includes: a first scale mark, which is set on the outer wall of the gas injection pipe and arranged along the direction from the first groove 37 to the fixed seat 34; a second scale mark 39, which is set on the outer wall of the gas injection pipe and arranged along the direction from the first groove 37 to the second groove 38; wherein the protective cover 31 is made of transparent material.

[0080] In this technical solution, the automatic pressure relief protector 3 can also include a first scale mark and a second scale mark 39. The first scale mark is used to indicate the pressure state of the air barrier when the self-pressure relief injection end 311 of the air injection tube is connected to the air hole 4, and the second scale mark 39 is used to indicate the pressure state of the air barrier when the high-pressure injection end 33 of the air injection tube is connected to the air hole 4.

[0081] It is understandable that the colors of the first scale mark and the second scale mark 39 can be different, so that medical staff can distinguish different working states of the insufflation tube. The colors of the first scale mark and the second scale mark 39 for different pressure states can also be different, so that medical staff can clearly understand the pressure safety state in the air isolation cuff 2. For example, when the pressure of the air isolation cuff 2 is relatively safe, the pressure numbers corresponding to the first scale mark and the second scale mark 39 can be green. On the contrary, when the pressure of the air isolation cuff 2 is relatively dangerous, the pressure numbers corresponding to the first scale mark and the second scale mark 39 can be green.

[0082] like Figure 7 As shown, according to the second aspect of the embodiment of the present application, a cuff inflation method for an automatic pressure relief endotracheal intubation device is proposed, which is applied to the automatic pressure relief endotracheal intubation device as any of the above technical solutions. The cuff inflation method includes:

[0083] Step 201: In response to a self-decompression gas injection instruction, controlling the high-pressure injection end of the gas injection pipe to be connected to the connecting pipe;

[0084] Step 202: injecting gas through the self-depressurizing injection end of the gas injection pipe until the sealing member is in the second groove, and then stopping the gas injection;

[0085] Step 203: In response to the high-pressure gas injection instruction, control the self-pressure relief injection end of the gas injection pipe to be connected to the connecting pipe;

[0086] Step 104: Inject gas through the high-pressure injection port.

[0087] When the air bag is inflated, the air bag is inflated and the air bag is inflated. When the air bag is inflated, the air bag is inflated and the air bag is inflated, the air bag is inflated and the air bag is inflated. When the air bag is inflated, the air bag is inflated and the air bag is inflated, the air bag is inflated and the air bag is inflated. When the air bag is inflated, the air bag is inflated and the air bag is inflated, the air bag is inflated and the air bag is inflated. To stop the gas injection, if the gas injection continues, the pressure in the gas barrier cuff will further increase. In this case, the pressure can overcome the force of gas injection, the seal will be in the second groove, and the gas injection tube will be connected again. In this case, it means that the pressure in the gas barrier cuff is already very high, and the gas injection should be stopped immediately. Based on this, the automatic pressure relief endotracheal intubation device provided by the embodiment of the present application can enable medical personnel to clearly understand the gas pressure of the gas barrier cuff, provide a basis for starting and stopping gas injection, improve efficiency, and be safer; further, in some cases, if higher pressure gas is injected into the gas barrier cuff, the end of the gas injection tube can be controlled to be closer to the second groove and connected to the connecting tube, the medical personnel can use a syringe to inject gas to the end of the gas injection tube closer to the fixed seat. In this case, the injected gas can push the seal to move to the second groove, and the gas injection tube is always in a conductive state, which makes the use of the automatic pressure relief endotracheal intubation device more convenient.
