Description

Technical Field

[0001] This utility model relates to the medical field, specifically a carbon dioxide detection device that can be adapted to multiple sizes of tube openings. Background Technology

[0002] In the fields of intensive care, anesthesia management, and respiratory therapy, carbon dioxide (CO2) concentration is a key indicator for assessing a patient's ventilation status, metabolic level, and respiratory circuit integrity. Medical carbon dioxide monitoring, specifically end-tidal carbon dioxide concentration monitoring, includes the monitoring of parameters such as end-tidal carbon dioxide (EtCO2), inhaled carbon dioxide (InsCO2), and airway respiratory rate (AwRR). It is one of the most important monitoring parameters for critically ill patients in key departments such as clinical ICU, OR, and ER. It is an important indicator for assessing a patient's ventilation status and external mechanical ventilation status, and is also one of the important parameters for ensuring patient safety. It is one of the high-end monitoring parameters in vital sign monitoring.

[0003] End-tidal carbon dioxide concentration effectively reflects the normality of the body's metabolism, respiration, circulation, and physiological state during processes such as anesthesia, thus providing timely and effective guidance for doctors to make correct treatment decisions for patients.

[0004] For example:

[0005] The standard treatment for cardiogenic shock is percutaneous cardiopulmonary support (PCP). Timely and appropriate use of this treatment can significantly improve the survival rate of patients with cardiogenic shock. To avoid organ failure and ensure normal cardiac function, non-invasive end-tidal carbon dioxide (ETC) monitoring is necessary to evaluate cardiac function and respiration during PCP. Furthermore, changes in ETC levels are more rapid than those observed with other hemodynamic monitoring methods. The rapid increase in ETC 24 hours after PCP effectively reflects the recovery of cardiac function.

[0006] In ECMO (extracorporeal membrane oxygenation) therapy, monitoring the CO2 concentration in the exhaust gas from the oxygenator can reflect the gas exchange efficiency of the artificial lung in real time and reflect the patient's oxygen metabolism.

[0007] Monitoring end-tidal CO2 (EtCO2) in patients with endotracheal intubation or tracheostomy can quickly identify catheter displacement, airway obstruction, or recovery of spontaneous breathing, thus avoiding hypoxia or hypercapnia caused by insufficient ventilation.

[0008] During mechanical ventilation, CO2 waveform analysis can help determine pathological conditions such as ventilation / perfusion mismatch and airway spasm.

[0009] Currently, carbon dioxide detectors typically use rigid connecting pipes with a fixed diameter. However, the exhaust interfaces of different medical devices vary significantly, leading to poor compatibility in actual operation. This necessitates the use of multiple adapter rings, increasing usage costs and operational complexity.

[0010] Therefore, there is an urgent need to develop a structure with adjustable tube diameter for easy docking, so that a single detector can be directly adapted to diverse scenarios such as ECMO and endotracheal intubation, thereby improving detection efficiency and convenience. Utility Model Content

[0011] The purpose of this invention is to provide a carbon dioxide detection device that can be adapted to multiple pipe sizes. It can adjust the size of the detector's interface according to the required joint conditions for adaptive assembly, thereby increasing the tightness and stability of the connection and reducing procurement costs.

[0012] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] A carbon dioxide detection device adaptable to multiple sizes of tube openings includes a housing, a sensor, and a detection tube. The sensor is integrated into the housing. The detection tube has two ends: a mating interface and an exhaust port. The mating interface can be plugged into and fixed with the exhaust connector of an existing medical device. The detection tube is provided with an adjustment component for adjusting the inner diameter of the mating interface at the position corresponding to the mating interface. The adjustment component is also provided with a reinforcement structure. The movement of the reinforcement structure is controlled to simultaneously connect the adjustment component and the outside of the exhaust connector.

[0014] Compared with existing technologies, the carbon dioxide detection device that adopts the above technical solution and can be adapted to multiple pipe sizes has the following advantages:

[0015] The carbon dioxide detection device of this invention, which is adaptable to multiple pipe sizes, utilizes an adjustment component to adjust the orifice diameter of the interface, thereby adapting to exhaust connectors of different pipe diameters for assembly and detection of carbon dioxide concentration. This effectively increases the versatility and flexibility of the carbon dioxide detection device. Simultaneously, a reinforced structure connects the adjustment component (detection pipe interface) and the exhaust connector, strengthening the connection and further increasing its stability and tightness. This improves the accuracy of the detection results and the sealing during testing. Furthermore, the exhaust port allows for the simultaneous discharge of carbon dioxide gas during detection.

[0016] Preferably, the adjusting assembly includes ring tubes and a compression layer. At least two ring tubes are provided, arranged sequentially with their diameters gradually decreasing from the outside to the inside. The middle ring tube is integrally connected to the detection tube. The ring tubes are connected via a mating portion. The compression layer is located on the inner wall of the ring tubes, and its inner wall has anti-slip textures. The edge of the compression layer away from the housing is an arc-shaped surface. By changing the aperture size of the detection tube end at the interface when the ring tubes are stretched and unstretched, the mating requirements of exhaust connectors with different tube holes can be met. Furthermore, the tensile force of the compression layer and the frictional resistance of the anti-slip textures effectively strengthen the connection and the airtightness of the interface. Additionally, the arc-shaped surface facilitates insertion during the mating process.

[0017] Preferably, the mating portion is flexibly configured so that when the outer ring pipe is pulled, the mating pipe detaches from the two connected ring pipes. The flexible mating portion allows for use with multiple ring pipes in an unstretched state, maintaining the connection between the multiple ring pipes and the piping at the interface.

[0018] Preferably, the reinforcement structure includes a positioning ring, a reinforcement ring, a control button, and a linkage assembly. The reinforcement ring is elastically set and is located on the inner wall of the positioning ring. The outermost ring tube has an annular groove for the positioning ring and reinforcement ring to enter and exit the annular tube. The control button is movably located on the outermost ring tube. The control button drives the positioning ring to extend out of the annular groove through the linkage assembly, and the reinforcement ring wraps around the outside of the exhaust connector. By controlling the positioning ring to enter and exit the annular tube, the position of the reinforcement ring can be adjusted. With the positions of the reinforcement ring and the positioning ring, the positioning ring can simultaneously wrap and fix the annular tube and the exhaust connector. Furthermore, the reinforcement ring enhances the connection effect, which not only increases the connection stability between the detection tube and the exhaust connector but also increases the sealing degree of the connection position, further increasing the accuracy of the detection results.

[0019] Preferably, the control button is a rotary structure, and the linkage component includes a toothed portion and a toothed ring. The toothed ring is fixedly arranged around the outer periphery of the control button, and the toothed portion is located on the outer periphery of the positioning ring facing the control button. Rotating the control button drives the positioning ring to move. Utilizing the meshing relationship of the toothed structure, rotating the control button can control the positioning ring, making the operation convenient and efficient, and easy for medical personnel to operate directly.

[0020] Preferably, the control button is connected to a locking lever on its externally located portion, and an elastic clamp is provided on the outermost ring wall. A color-coded indicator surface is provided on the outer periphery of the gear ring. Rotating the control button causes the locking lever to move in and out of the elastic clamp, exposing the color-coded indicator surface to the outside. The locking lever and the elastic clamp work together to lock the reinforced structure in its operational state, and the color-coded indicator surface clearly indicates whether the structure is currently locked.

[0021] Preferably, the positioning ring has a limiting block at its end near the housing, and an anti-detachment block is provided inside the outermost ring tube to allow the limiting block to move. During the control of the positioning ring's movement, the cooperation of the limiting block and the anti-detachment block restricts the end of the positioning ring near the housing, thus preventing excessive displacement and separation of the positioning ring. It also allows medical personnel to easily adjust the control knob to its full position without worrying about excessive operation, facilitating quick operation and reducing the time spent on operation.

[0022] Preferably, both the interface and the exhaust port are equipped with adjustment components, and the exhaust port can be connected to an external carbon dioxide detection device or other existing gas detection devices. If further detection or displacement monitoring is required, the exhaust port can be connected to an external device through the adjustment components. Attached Figure Description

[0028] The present invention will now be further described with reference to the accompanying drawings.

[0029] like Figures 1 to 4 The carbon dioxide detection device shown is adaptable to multiple sizes of nozzles and includes a housing 1, a sensor, a control module, and a detection tube 2.

[0030] The sensor and control module are integrated in the housing 1. The sensor can refer to existing gas concentration detection sensors, such as the Mindray Capnostat 5 CO2 sensor.

[0031] The detection tube 2 is divided into an interface 3 and an exhaust port 4 at both ends. The interface 3 can be plugged into and fixed with the exhaust connector 0 of the existing medical device. The detection tube 2 is equipped with an adjustment component for adjusting the inner diameter of the interface 3 at the position corresponding to the interface 3.

[0032] The regulating assembly includes a ring tube 20 and an extrusion layer 21.

[0033] Among them, the ring tube 20 is a structure at the end of the detection tube 2. There are at least two ring tubes 20. Multiple ring tubes 20 are arranged in sequence and the diameter gradually decreases from the outside to the inside. The middle ring tube 20 is integrated with the detection tube 2. Multiple ring tubes 20 are connected to each other through the docking part 22. The extrusion layer 21 is provided on the inner wall of the ring tube 20, and the inner wall of the extrusion layer 21 is provided with anti-slip texture. The edge of the extrusion layer 21 away from the shell 1 is an arc surface.

[0034] The docking part 22 is flexibly designed so that when the outer ring tube 20 is pulled, the connecting tube detaches from the two connected ring tubes 20.

[0035] The adjustment component is also equipped with a reinforcing structure 5, and the movement of the reinforcing structure 5 is controlled to simultaneously connect the adjustment component and the outer side of the exhaust connector 0.

[0036] The reinforcing structure 5 includes a positioning ring 50, a reinforcing ring 51, a control button 52, and a linkage assembly.

[0037] The reinforcing ring 51 is elastically set and is located on the inner wall of the positioning ring 50. The outermost ring tube 20 is provided with an annular groove 53 for the positioning ring 50 and the reinforcing ring 51 to enter and exit the ring tube 20. The control button 52 is movably located on the outermost ring tube 20. The control button 52 drives the positioning ring 50 to extend out of the annular groove 53 through the linkage component, and the reinforcing ring 51 wraps around the outside of the exhaust connector 0.

[0038] For ease of operation, the control button 52 is a rotary structure. The linkage component includes a toothed part 54 and a toothed ring 55. The toothed ring 55 is fixedly arranged around the outer periphery of the control button 52. The toothed part 54 is located on the outer periphery of the positioning ring 50 facing the control button 52. Rotating the control button 52 drives the positioning ring 50 to move.

[0039] To lock the use status of the reinforced structure 5, the control button 52 is connected to a locking rod 6 on the external part. The outermost ring tube 20 has an elastic clamp 60 on its outer wall, and the outer periphery of the toothed ring 55 has a color indicator surface 7. Rotating the control button 52 causes the locking rod 6 to move in and out of the elastic clamp 60, and exposes the color indicator surface 7 to the outside.

[0040] In order to avoid the problem of the positioning ring 50 separating due to excessive operation of the control button 52, a limiting block 8 is provided at the end of the positioning ring 50 near the housing 1, and an anti-detachment block 80 is provided inside the outermost ring tube 20, which allows the limiting block 8 to move, and the anti-detachment block 80 is partially connected to the ring groove 53.

[0041] In addition, the positioning ring 50 and reinforcing ring 51 in the main body of the detection tube 2, the ring tube 20, and the reinforcing structure 5 are not limited to circular ring structures, but can also be square tubes, triangular tubes, etc., which can be adapted to the exhaust connectors 0 of different medical devices.

[0042] In addition, such as Figure 4 As shown, the adjustment component of this invention can be installed not only at the interface 3, but also at both the interface 3 and the exhaust port 4. The exhaust port 4 can be connected to an external carbon dioxide detection device or other existing gas detection devices.

[0043] During use, first, based on the pipe diameter of the exhaust connector 0 to be connected, if an ECMO needs to be connected, select a suitable ring tube 20 according to the pipe diameter of the ECMO's exhaust connector 0. Stretch multiple ring tubes 20 or directly insert and fix them onto the outer part of the exhaust connector 0. Next, rotate the control knob 52. Due to the meshing relationship between the control knob 52 and the outer side of the positioning ring 50, the positioning ring 50 moves towards the exhaust connector 0, so that part of the positioning ring 50 is located in the annular groove 53 of the outermost ring tube 20, and the other part is located outside the exhaust connector 0. The reinforcing ring 51 tightly wraps and fixes itself to the exhaust connector 0. Continue rotating the control knob 52, so that the locking rod 6 is embedded in the elastic clamp 60, and the color indicator surface 7 is exposed to the outside. For exhaust connectors 0 with larger pipe diameters, this can achieve reinforcement of the connection state during connection. Afterwards, the control module inside the sensor and detection device can be operated to detect the carbon dioxide concentration emitted by the ECMO.

[0044] If further detection of concentration or carbon dioxide emissions is required, the detection device of this case, which may also have an adjustment component and a reinforcement structure 5, can be selected to connect the exhaust port 4 to other gas detection devices.

[0045] The above description is a preferred embodiment of the present utility model. For those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered within the protection scope of the present utility model.
