Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to an auxiliary treatment device for sepsis patients. BACKGROUND

[0002] Sepsis is a systemic inflammatory response syndrome caused by infection, which can rapidly progress to severe sepsis and septic shock, accompanied by multiple organ dysfunction, among which the respiratory system is one of the most vulnerable target organs. According to clinical data, about 40%-50% of sepsis patients will develop acute respiratory distress syndrome (ARDS) or respiratory failure, at which time they need to rely on mechanical ventilation and other auxiliary breathing equipment to maintain vital signs. However, the existing breathing auxiliary devices for sepsis patients still have many technical defects in clinical application, which are difficult to meet the special treatment needs of sepsis patients.

[0003] Firstly, the insufficient stability of the tracheal tube fixation is one of the main problems in clinical practice. Sepsis patients often have symptoms such as high fever, restlessness, delirium, etc., and the body activity increases, which easily leads to displacement or shedding of the tracheal tube. The current commonly used fixation methods in clinical practice mostly rely on adhesive tape sticking or fixing belt binding, which not only has limited fixation strength, but also easily leads to complications such as skin damage and pressure sores on the patient's face after long-term use. In addition, the traditional fixation structure cannot dynamically adjust the fixation strength according to the patient's respiratory rhythm or body position changes. When the patient coughs or chokes, the impact force on the tracheal tube may increase instantaneously, further increasing the risk of shedding. Once the tracheal tube is shed, it will lead to hypoxia and carbon dioxide retention in the patient, and even cause cardiac arrest, which has a fatal impact on the prognosis of sepsis patients.

[0004] Secondly, there is a lack of self-adaptive adjustment mechanism linked with the respiratory rhythm. The respiratory pattern of sepsis patients is often unstable, and may have conditions such as increased respiratory rate and large tidal volume. The internal structure of the existing tracheal tube is fixed and cannot adjust the channel diameter or resistance according to the change in airflow pressure. When the patient's inspiratory effort is increased, the airflow speed may be too fast to cause impact on the airway mucosa; while during exhalation, if the channel resistance is too large, it will increase the burden on the respiratory muscles. At the same time, the anti-shedding structure of the traditional device is not linked with the respiratory process, and cannot trigger dynamic adjustment of the fixation strength through the pressure change of the respiratory airflow, leading to the contradiction between "loose fixation and easy shedding" and "tight fixation and mucosa damage" being difficult to balance.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention provides a technical solution: such as Figures 1-9 The illustrated adjunctive treatment device for sepsis patients includes a ventilator body 2, an inspiratory tube 4 and an expiratory tube 5 connected to the ventilator body 2; a Y-connector 6 connected to the ends of the inspiratory tube 4 and the expiratory tube 5 respectively, with the other end of the Y-connector 6 connected to an intubation tube 7; an anti-dislodgement component 9 on the intubation tube 7; an exhaust pipe 8 at the outlet end of the intubation tube 7; an adjusting block 15 and an adjusting plate 21 that cooperate with each other inside the intubation tube 7; and a pump tube 12 inside the intubation tube 7 for adjusting... The bottom surface of the section plate 21 is provided with a piston rod 22. One end of the piston rod 22, which is placed inside the air pump pipe 12, is provided with a cup 28. The air outlet end of the air pump pipe 12 is provided with an air supply pipe 10 and an air supply pipe 21, respectively. The air supply pipe 10 is used to supply air to the anti-detachment component 9. The insertion tube 7 is provided with a movable groove 38. A sliding strip 25 is slidably connected in the movable groove 38. Multiple equidistant limiting protrusions 27 are provided on the sliding strip 25. The air supply pipe 21 is connected to the movable groove 38.

[0029] In the present application, the inspiration stage: the gas generated by the ventilator body 2 enters the humidifier 3 through the inspiration pipe 4, and after humidification treatment, it flows into the Y-shaped joint 6 through the remaining section of the inspiration pipe 4, and then is guided to the cannula 7 by the Y-shaped joint 6, and finally is delivered to the patient's respiratory tract through the cannula 7. If the cannula 7 is connected with the exhaust pipe 8 at the end, the gas enters the respiratory tract through the straight pipe 801 after being buffered by the conical pipe 802 of the exhaust pipe 8. At this time, the expiration pipe 5 is in a closed state to avoid gas backflow.

[0030] The expiration stage: the gas exhaled by the patient flows back to the Y-shaped joint 6 through the cannula 7, and then returns to the ventilator body 2 through the expiration pipe 5 for treatment.

[0031] The adjusting block 15 drives the sliding plate 18 to move downward, the sliding plate 18 pushes the adjusting plate 21 to move downward, the piston rod 22 at the bottom of the adjusting plate 21 drives the leather cup 28 to move downward in the pump gas pipe 12, the gas in the pump gas pipe 12 enters the airway 29 and enters the air chamber two 34, the blocking piece two 35 in the air chamber two 34 is pushed away by the gas and the elastic piece five 36 is compressed, the gas enters the inflation ring 901 of the anti-dropping piece 9 through the gas conveying pipe one 10, the convex air bag 902 expands and adheres to the inner wall of the patient's respiratory tract, realizing the anti-dropping fixation of the cannula 7.

[0032] At the same time, part of the gas in the pump gas pipe 12 enters the air chamber one 30, the blocking piece one 31 in the air chamber one 30 is pushed away (the elastic piece four 32 is stretched), the gas enters the movable groove 38 of the cannula 7 through the gas conveying pipe two 11, and drives the sliding bar 25 to move, the limiting protruding block 27 on the sliding bar 25 protrudes from the inner wall of the cannula 7, and a plurality of groups of limiting protruding blocks 27 are equidistantly arranged, when the limiting protruding blocks 27 protrude, they just limit the adjusting plate 21, and the adjusting plate 21 can only move within the range of the two adjacent limiting protruding blocks 27, thereby reducing the discomfort caused to the patient by large pressure fluctuation.

[0033] Reference Figures 1-9 The ventilator body 2 is installed through the support 1, the support 1 is provided with an installation slot 101, the installation slot 101 is provided with an installation plate 102, the installation plate 102 is provided with a humidifier 3, and the gas inlet end and the gas outlet end of the humidifier 3 are connected with the inspiration pipe 4.

[0034] The support 1 is integrally formed by high-strength aluminum alloy material, the bottom can be fixed by four universal wheels with brakes, which is convenient for medical staff to flexibly adjust the position of the device according to the patient's body position (such as semi-recumbent position with the head of the bed raised by 30°); a vertical section of the support 1 is provided with an installation slot 101 with a length of 60 cm, the installation slot 101 is a "T"-shaped slot structure with a width of 8 cm and a depth of 5 cm, and three groups of anti-skid rubber strips (with a spacing of 20 cm) are symmetrically arranged on the two side walls of the slot for enhancing the fixing friction of the installation plate 102 and avoiding displacement due to vibration during equipment operation.

[0035] The inspiration pipe 4 and the expiration pipe 5 are made of medical PVC material.

[0036] Reference Figures 1-9 , the exhaust pipe 8 is composed of a straight pipe 801 and a tapered pipe 802, wherein the large-diameter end of the tapered pipe 802 faces the cannula 7, and the small-diameter end of the tapered pipe 802 is connected with the straight pipe 801.

[0037] The advantage of such design is that, in the inhalation stage, the humidified gas from the cannula 7 enters the exhaust pipe 8, first passing through the large-diameter end of the tapered pipe 802, and converting the turbulent gas flow that may exist into stable laminar flow by virtue of the gradually tapered pipe diameter (for example, smoothly transitioning from 2 cm to 1.2 cm), thereby reducing the gas flow speed and uniformly distributing the pressure; such buffering effect can avoid the direct impact of high-speed gas on the respiratory tract of the patient, and for patients with sepsis, the airway mucosa is in a hyperemic and fragile state due to inflammation, and this can significantly reduce the risk of mucosal damage, spasm or bleeding.

[0038] Subsequently, the buffered gas enters the straight pipe 801, which has a constant pipe diameter (such as 1.2 cm) that is closer to the pipe diameter of the patient's respiratory tract (about 1.5-2.5 cm for adults), thereby reducing the vortex and resistance of the gas during delivery, ensuring smooth flow of the gas into the deep part of the lung, and improving the ventilation efficiency; at the same time, the end of the straight pipe 801 is usually designed as a rounded bevel, further reducing the mechanical stimulation to the airway during insertion, and adapting to the characteristics of patients with sepsis who need long-term cannula 7 and have low tolerance.

[0039] Reference Figures 1-9 The anti-disengagement piece 9 is provided in multiple groups and is equidistantly arranged on the shaft of the cannula 7, and the anti-disengagement piece 9 is composed of an inner inflatable ring 901 and an outer convex air bag 902.

[0040] In the present application, for the 8-10 cannula 7 commonly used for adult patients with sepsis, at least two groups of anti-disengagement pieces 9 are arranged along the shaft of the cannula 7; the first group near the Y-shaped joint 6 is 10 cm away from the top end of the cannula 7, and the last group is 5 cm away from the exhaust pipe interface, which can cover the key fixed area of the cannula 7 inserted into the respiratory tract.

[0041] The inflatable ring 901 is made of medical latex material and is embedded in the annular groove on the outer wall of the cannula 7, and is in communication with the gas delivery pipe 10 through multiple branch pipes, so as to ensure that each group of anti-disengagement pieces 9 expands synchronously when inflated, the pressure is uniform, and the internal air pressure is maintained at 20-25 cmH2O after inflation, which is suitable for the tolerance range of the respiratory tract mucosa.

[0042] The convex air bag 902 is designed: the outer convex air bag 902 is made of silica gel material, and is integrally formed with the inflation ring 901. Each set of anti-disengagement piece 9 contains at least six evenly distributed semispherical convex points, with a diameter of 0.8 cm and a height of 0.5 cm. The convex point surface is smooth and the edge is round. After inflation, it can form multiple point contact with the inner wall of the respiratory tract, which not only enhances the friction to prevent the intubation tube 7 from sliding, but also avoids the mucosal ischemia caused by single point compression.

[0043] Clinical adaptability: when not inflated, the convex air bag 902 completely fits the outer wall of the intubation tube 7, does not increase the intubation tube 7 insertion diameter, and ensures smooth passage through the glottis; after inflation, the overall diameter increases by 1.5-2 cm compared to the original diameter of the intubation tube 7, which can adapt to the tracheal diameter of different patients. The adult tracheal diameter is usually 1.5-2.5 cm. In addition, the elastic properties of latex and silica gel can buffer the instantaneous impact force when the patient coughs, reducing the risk of displacement of the intubation tube 7.

[0044] Reference Figures 1-9 The bottom plate 13 and the upper cover plate 14 are respectively arranged at both ends of the pump air pipe 12. The upper cover plate 14 is provided with an air inlet hole 24. The elastic member two 23 is arranged between the adjusting plate 21 and the upper cover plate 14, and the elastic member two 23 is sleeved on the piston rod 22. The bottom plate 13 is provided with an air channel 29 communicating with the inside of the pump air pipe 12. The air channel 29 is connected with the air chamber one 30 and the air chamber two 34 in parallel. The air chamber one 30 and the air chamber two 34 are respectively provided with the blocking piece one 31 and the blocking piece two 35. The blocking piece one 31 and the blocking piece two 35 are respectively provided with the elastic member four 32 and the elastic member five 36. The gas delivery pipe one 10 is connected with the air chamber two 34 through the air guide hole two 37. The gas delivery pipe two 11 is connected with the air chamber one 30 through the air guide hole one 33. The adjusting block 15 is an arc inclined block. The diameter of the channel formed by the adjusting block 15 and the intubation tube 7 decreases as it is closer to the Y-shaped joint 6. The adjusting block 15 is provided with the fixed rod 16. The top of the fixed rod 16 is provided with the limiting plate 19. The fixed rod 16 is slidably connected with the sliding plate 18. The sliding plate 18 is arranged below the limiting plate 19. The elastic member one 17 is arranged between the adjusting block 15 and the sliding plate 18. The sliding plate 18 and the adjusting plate 21 are connected with the push rod 20.

[0045] In one embodiment, during inhalation, the airflow pressure in the intubation tube 7 increases. Because the adjusting block 15 is an arc inclined block (the diameter of the channel formed by the adjusting block 15 and the intubation tube 7 decreases as it is closer to the Y-shaped joint 6), the airflow pushes the adjusting block 15 to move towards the Y-shaped joint 6. The adjusting block 15 drives the sliding plate 18 to move downward through the fixed rod 16, compressing the elastic member one 17. The sliding plate 18 drives the adjusting plate 21 to move downward through the push rod 20, and then the piston rod 22 in the bottom surface of the adjusting plate 21 drives the rubber cup 28 to move downward in the pump air pipe 12 (the two ends of the pump air pipe 12 are sealed by the bottom plate 13 and the upper cover plate 14, and the air inlet hole 24 of the upper cover plate 14 supplements air).

[0046] Reference Figures 1-9The elastic member three 26 is arranged between the bottom surface of the active groove 38 and the sliding strip 25.

[0047] Working principle: the ventilator body 2 is fixed through the support 1, the mounting groove 101 of the support 1 is arranged with the mounting plate 102, the humidifier 3 is fixed on the mounting plate 102, the gas inlet end and the gas outlet end of the humidifier 3 are communicated with the inhalation pipe 4, and the humidifier 3 is used for humidifying the inhaled gas, so that the dry gas is avoided from stimulating the respiratory tract of the patient.

[0048] The inhalation pipe 4 and the exhalation pipe 5 of the ventilator body 2 are respectively connected to two branch ends of the Y-shaped joint 6, the other end of the Y-shaped joint 6 is communicated with the cannula 7, and the gas passage of "ventilator-pipeline-patient respiratory tract" is formed. The gas outlet end of the cannula 7 is connected to the exhaust pipe 8, and the exhaust pipe 8 is composed of the conical pipe 802 and the straight pipe 801, wherein the large-diameter end of the conical pipe 802 faces the cannula 7, and the small-diameter end is connected to the straight pipe 801. The impact force of the exhaled gas can be buffered through the conical structure, and the pressure fluctuation of the respiratory tract is reduced.

[0049] Inhalation stage: the gas generated by the ventilator body 2 enters the humidifier 3 through the inhalation pipe 4, is humidified, and then enters the Y-shaped joint 6 through the remaining inhalation pipe, and then flows into the exhaust pipe 8 through the cannula 7, and then sequentially passes through the conical pipe 802 and the straight pipe 801, and finally is delivered to the respiratory tract of the patient. The exhaust pipe 8 serves as an extension between the cannula 7 and the respiratory tract at this time, and the conical pipe 802 can play a buffering role before the gas enters the respiratory tract, reducing the direct impact of the gas flow on the respiratory tract, and being more suitable for the respiratory tract nursing needs of patients with sepsis. At this time, the exhalation pipe 5 is in a closed state to avoid gas backflow.

[0050] Exhalation stage: the exhaled gas of the patient enters the Y-shaped joint 6 through the cannula 7, and then flows back to the ventilator body 2 through the exhalation pipe 5.

[0051] The adjusting block 15 drives the sliding plate 18 to move downward through the fixed rod 16, the push rod 20 below the sliding plate 18 pushes the adjusting plate 21 to move downward, and the piston rod 22 at the bottom of the adjusting plate 21 drives the leather cup 28 to move downward in the pump gas pipe 12. The two ends of the pump gas pipe 12 are sealed by the bottom plate 13 and the upper cover plate 14, and the air inlet hole 24 of the upper cover plate 14 is used for supplementing air. At this time, the gas in the pump gas pipe 12 enters the gas chamber two 34 through the air channel 29 of the bottom plate 13, the blocking member two 35 in the gas chamber two 34 is pushed open by the gas, the elastic member five 36 is compressed, the gas enters the inflation ring 901 of the anti-dropping piece 9 through the gas conveying pipe one 10, the convex air bag 902 is inflated and adheres to the inner wall of the respiratory tract of the patient, and the anti-dropping fixation of the cannula 7 is realized.

[0052] At the same time, part of the gas in the airway 29 enters the air chamber 1 30, the blocking piece 1 31 in the air chamber 1 30 is pushed away (the elastic piece 4 32 is stretched), the gas enters the movable groove 38 of the cannula 7 through the gas delivery pipe 2 1 1, pushes the sliding bar 25 to move, and the limiting protrusions 27 on the sliding bar 25 protrude from the inner wall of the cannula 7. The limiting protrusions 27 are equidistantly provided, and when they protrude, they just limit the adjusting plate 21. The adjusting plate 21 can only move within the range of the two adjacent limiting protrusions 27, so as to reduce the discomfort caused by large pressure fluctuations to the patient.

[0053] It should be noted that the force for pushing the blocking piece 1 31 is greater than that for pushing the blocking piece 2 35 (that is, the elastic coefficient of the elastic piece 4 32 is greater than that of the elastic piece 5 36, and the blocking piece 1 31 needs a greater pushing force than the blocking piece 2 35). Because when the pressure fluctuation is large, the patient needs to frequently change the breathing state, thereby aggravating the disease. At this time, the limiting protrusions 27 on the sliding bar 25 protrude from the inner wall of the cannula 7, so that the adjusting plate 21 can only move within the range of the two adjacent limiting protrusions 27.

[0054] The device provides an innovative solution to the two core problems in the respiratory support of sepsis patients:

[0055] Revolutionary anti-disengagement stability: The "double dynamic anti-disengagement mechanism" (self-adaptive fitting anti-disengagement piece 9 + exhalation-triggered limiting protrusion 27) driven by respiratory airflow provides the strongest fixing force in the exhalation phase (coughing, restlessness) when the patient is most likely to disengage the tube, actively reduces the constraint in the inhalation phase, significantly reduces the risk of accidental extubation, and ensures ventilation safety.

[0056] Intelligent respiratory synchronization adaptation: The adjusting block 15 and the adjusting plate 21 linkage structure responds to the inhalation pressure in real time, automatically expands the ventilation channel to reduce resistance, and accurately switches the pumping and valve system to ensure that the anti-disengagement and limiting actions are only strengthened in the exhalation phase. This perfect fit with respiratory physiology reduces the work done by the patient's breathing and reduces the man-machine confrontation, especially suitable for sepsis patients with unstable breathing patterns.

[0057] Excellent patient tolerance: Multiple equidistantly distributed anti-disengagement pieces 9 combined with flexible convex airbags 902 design maximize the dispersion of contact pressure; the conical exhaust pipe 8 buffers the airflow; and the integrated humidification protects the mucosa. These designs significantly reduce the complications (mucosal damage, pressure necrosis, airway dryness) related to the cannula 7, improve patient comfort and compliance.

[0058] Reliability and economy: The pure mechanical structure does not require circuits and additional power, has low failure rate, is easy to maintain, has no response delay, reduces equipment cost and operating energy consumption, and is very suitable for high-risk and high-load clinical environments such as ICUs.
