Description

Technical Field

[0001] This application belongs to the field of anesthesia medical device technology, and more specifically, relates to a condenser and anesthesia machine. Background Technology

[0002] During inhalation anesthesia, the patient's exhaled air contains a large amount of water vapor. This water vapor mainly comes from two sources: firstly, the patient's exhaled air itself contains water vapor; secondly, water vapor is produced after the patient's exhaled carbon dioxide reacts with the calcium lime in the carbon dioxide absorber. The latter, in particular, generates a large amount of heat during the reaction, raising the temperature by 10-30°C, thus producing even more water vapor.

[0003] When these hot and humid gases flow through the cooler metal components of the anesthesia breathing circuit, condensation occurs, forming condensate in the circuit. Excessive condensate buildup can severely impact the normal operation of the anesthesia machine. For example, condensation may affect the opening and closing function of the expiratory / inspiratory valves or interfere with the measurement accuracy of flow and pressure sensors, thereby disrupting the normal function of the breathing circuit.

[0004] To address this issue, existing technologies primarily employ two solutions: First, a drainage principle is used to direct condensate to spaces that do not affect function, such as calcium lime tanks, or to easily drained spaces like air reservoirs or corrugated pipes. Second, a heated anesthesia circuit system is used to prevent water accumulation within the circuit through constant-temperature heating.

[0005] However, these existing technological solutions all have significant drawbacks. Drainage techniques require periodic removal of water from the circuit, making the process complex and time-consuming, and easily contaminating the operating room environment. Heating systems may exacerbate heat retention in patients with high fever or in high-temperature environments, while also increasing the manufacturing cost of the anesthesia machine and the risk of circuit failure.

[0006] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0013] Furthermore, the drain port has a stepped portion, and the first end of the connecting pipe has a limiting portion; when the connecting pipe is connected to the condenser body, the limiting portion abuts against the stepped portion.

[0014] Furthermore, an annular groove is provided on the outer peripheral surface of the first end of the connector, and a sealing ring is provided in the annular groove.

[0015] Furthermore, the second end of the connector has an internal thread, the liquid collection device has an external thread, and the connector is threadedly connected to the liquid collection device.

[0016] Furthermore, the liquid collection device is a transparent bottle or a semi-transparent bottle.

The liquid collection device is detachably connected to the condenser body at the drain port, allowing for quick removal and replacement when the liquid in the device is full.

[0033] Please refer to the following: Figure 1 and Figure 2 The condenser provided in the embodiments of this application will now be described. The condenser includes a condenser body 100 and a liquid collection device 200; the condenser body 100 has an air inlet 110, an air outlet 120 and an internal cavity 130, the internal cavity 130 is connected to the air inlet 110 and the air outlet 120; a liquid drain port 140 is provided at the bottom of the internal cavity 130; the outer peripheral surface of the condenser body 100 has a plurality of fins 150; the liquid collection device 200 is detachably connected to the condenser body 100 at the liquid drain port 140.

[0034] Compared with the prior art, the condenser provided in this application effectively solves the problem of water accumulation during use by providing a drain port 140 at the bottom of the internal cavity 130 of the condenser body 100, and detachably connecting a liquid collection device 200 to the drain port 140. Multiple fins 150 are provided on the outer circumferential surface of the condenser body 100 to increase the surface area of ​​the condenser, which is more conducive to heat exchange between the condenser and the room, maintaining the condenser temperature at approximately the same level as the room temperature, and thus improving the condensation effect. The liquid collection device 200 allows for convenient drainage of condensate, preventing condensate from accumulating in the internal cavity 130 of the condenser and ensuring normal operation. The liquid collection device 200 is detachably connected to the condenser body 100 at the drain port 140, and can be quickly removed and replaced when the liquid in the liquid collection device 200 is full.

[0035] In one embodiment of this application, please refer to Figure 2 Along the drain direction of the drain port 140, the lower surface of the internal cavity 130 is lower than the lower surface of the air inlet port 110 and / or the air outlet port 120.

[0036] In this embodiment, along the drain direction of the drain port 140, the lower surface of the internal cavity 130 is lower than the lower surface of the air inlet 110 and / or the air outlet 120. This design allows the condensate inside the condenser to flow more smoothly to the drain port 140, thereby effectively discharging the condensate and preventing it from flowing out of the air inlet 110 or the air outlet 120, thus avoiding the accumulation of condensate inside the condenser. In this way, condensate accumulation inside the condenser can be prevented, thereby ensuring the normal operation of the condenser and avoiding affecting the heat exchange efficiency and overall performance of the condenser.

[0037] In this application, along the drainage direction of the drain port 140, the lower surface of the internal cavity 130 is lower than the lower surfaces of the air inlet 110 and / or the air outlet 120. Specifically, this design can be achieved in several ways: First, the lower surface of the internal cavity 130 can be designed as an inclined surface, gradually decreasing in elevation along the drainage direction. Second, a guide groove can be provided on the lower surface of the internal cavity 130 to further guide the condensate to flow towards the drain port 140. As a preferred embodiment, small protrusions or depressions can also be added to the lower surface to enhance the condensate drainage effect.

[0038] This application effectively solves the problem of condensate buildup by designing the lower surface of the internal cavity 130 to be lower than the lower surface of the air inlet 110 and / or air outlet 120. Compared with the prior art, this application's design can discharge condensate more efficiently, reducing the complex process and time-consuming nature of periodically draining accumulated water, and avoiding contamination of the operating room environment. Furthermore, this application eliminates the need for an additional heating system, thus avoiding increased manufacturing costs and the risk of circuit failure, making it suitable for use in various temperature environments. Therefore, this application significantly improves the working efficiency and reliability of the condenser.

[0039] In one embodiment of this application, please refer to Figure 2 The fins 150 are arranged perpendicular to the outer surface of the condenser body 100, and the multiple fins 150 are arranged at intervals along the circumferential direction of the condenser body 100.

[0040] In this embodiment, the vertical arrangement of the fins 150 helps to improve the efficiency of airflow, thereby enhancing the condensation effect. The multiple fins 150 are spaced along the circumference of the condenser body 100, ensuring uniform heat dissipation in all directions on the condenser surface, thus further improving condensation efficiency.

[0041] In this embodiment, the fins 150 can be made of metallic materials, such as aluminum or copper, which have good thermal conductivity. The number and spacing of the fins 150 can be adjusted according to the size of the condenser and the operating environment to achieve the best condensation effect. The shape of the fins 150 can be straight or corrugated to increase airflow turbulence and further improve heat dissipation.

[0042] Compared to existing technologies, this application achieves a more efficient condensation effect by vertically arranging fins 150 on the outer surface of the condenser and spacing them along the circumference. This design not only improves the heat dissipation capacity of the condenser but also ensures uniform heat dissipation in all directions on the condenser surface, avoiding localized overheating and thus improving the overall efficiency and reliability of the condenser.

[0043] In one embodiment of this application, please refer to the following: Figure 1 and Figure 2 The condenser also includes a connecting pipe 300, the first end of which is detachably connected to the condenser body 100 at the drain port 140; the second end of the connecting pipe 300 is detachably connected to the liquid collection device 200.

[0044] In this embodiment, by adding a connecting pipe 300 between the condenser body 100 and the liquid collection device 200, condensate can be smoothly discharged and collected into the liquid collection device 200. This design not only facilitates cleaning and maintenance but also ensures that condensate does not accumulate inside the condenser, thereby avoiding affecting the normal operation of the condenser. Furthermore, the detachable connection design makes the installation and removal of the connecting pipe 300 and the liquid collection device 200 more convenient, improving the overall maintainability and reliability of the equipment.

[0045] In one embodiment of this application, the first end of the connector 300 is snapped into the condenser body 100.

[0046] This application effectively improves the stability and sealing of the connection by using a snap-fit ​​design between the first end of the connector 300 and the condenser body 100. Compared with the prior art, it avoids the problem of condensate leakage caused by unstable connection, simplifies the structural design, and reduces the complexity of use and maintenance.

[0047] Specifically, the snap-fit ​​connection can be achieved in several ways. For example, the first end of the connecting pipe 300 can be designed with a flexible snap-fit ​​structure, which automatically engages when inserted into the corresponding interface of the condenser body 100, thus achieving a secure connection. Another approach is to have a tapered design at the first end of the connecting pipe 300, which, through its cooperation with the interface of the condenser body 100, achieves a tight snap-fit ​​connection. Furthermore, an annular groove 320 can be provided on the outer circumferential surface of the connecting pipe 300, and a sealing ring can be placed within the groove to further enhance the sealing effect.

[0048] In one embodiment of this application, please refer to Figure 3 The drain port 140 has a stepped portion 141, and the first end of the connecting pipe 300 has a limiting portion 310; when the connecting pipe 300 is connected to the condenser body 100, the limiting portion 310 abuts against the stepped portion 141.

[0049] Specifically, the stepped portion 141 and the limiting portion 310 abut against each other, ensuring a stable connection between the connecting pipe 300 and the condenser body 100, preventing the connecting pipe 300 from loosening or falling off during use, thereby improving the reliability and service life of the condenser. At the same time, by providing the stepped portion 141 and the limiting portion 310, it is also possible to prevent the structure from extending into the internal cavity 130, thus avoiding interference with the discharge of condensate. Through the above technical solution, the condenser can effectively maintain a stable connection between the connecting pipe 300 and the condenser body 100 during use, solving potential problems caused by unstable connections.

[0050] In one embodiment of this application, please refer to Figure 5 An annular groove 320 is provided on the outer peripheral surface of the first end of the connector 300, and a sealing ring (not shown) is provided in the annular groove 320.

[0051] In this embodiment, by employing the annular groove 320 and a sealing ring, a reliable seal is achieved at the connection between the pipe 300 and the condenser body 100, preventing condensate leakage. Compared with existing technologies, this design simplifies the condensate treatment process, reduces the complexity and frequency of maintenance, and avoids equipment failures and environmental pollution caused by condensate leakage. Therefore, the design of this application significantly improves the service life and reliability of the condenser, possessing high practical value and technological advancement.

[0052] In this embodiment, the annular groove 320 can be formed on the outer circumferential surface of the pipe 300 by machining or molding. The sealing ring can be made of materials with good elasticity and corrosion resistance, such as rubber or silicone. The size of the sealing ring should match the size of the annular groove 320 to ensure a good sealing effect. Furthermore, the sealing ring can be an O-ring, a U-ring, or other structural forms with sealing functions to adapt to different application requirements.

[0053] In one embodiment of this application, please refer to Figure 5 The second end of the connector 300 has an internal thread 330. Please refer to [link / reference]. Figure 4 The liquid collection device 200 has an external thread 210, and the connecting pipe 300 is threadedly connected to the liquid collection device 200.

[0054] This application solves the problems of unstable connection and poor sealing that may occur during condensate drainage by using a threaded connection to tightly connect the pipe 300 and the liquid collection device 200. Compared with the prior art, this application provides a more reliable and convenient connection method, ensuring that condensate can be discharged smoothly and avoiding equipment failure and environmental pollution caused by leakage or loosening. Therefore, this application improves equipment stability and sealing while simplifying the maintenance process and reducing operational complexity.

[0055] In this embodiment, the second end of the connecting pipe 300 has an internal thread 330, and the liquid collection device 200 has an external thread 210. This design allows the connecting pipe 300 and the liquid collection device 200 to be reliably mechanically connected via a threaded connection. The threaded connection not only provides a stable connection but also enhances the sealing effect and prevents liquid leakage. Furthermore, the threaded connection design makes replacing the liquid collection device 200 more convenient; users can simply rotate it to complete disassembly and installation, making operation simple and maintenance convenient. As a preferred embodiment, the threads of the connecting pipe 300 and the liquid collection device 200 can adopt standardized thread specifications to ensure compatibility and versatility. Furthermore, a sealing ring can be added at the threaded connection to further enhance the sealing performance and ensure a good sealing effect even under high pressure or high temperature environments.

[0056] In one embodiment of this application, the liquid collection device 200 is a transparent bottle or a semi-transparent bottle.

[0057] This application effectively solves the problem of condensation buildup in the breathing circuit affecting the function of the anesthesia machine by using a transparent or semi-transparent condensation device 200. Compared with the prior art, the advantages of this application are that it can monitor the condensation in real time, reducing interference with the function of the anesthesia machine and lowering maintenance complexity and contamination risk. With this design, medical staff can clean or replace the condensation more promptly, ensuring the stable operation of the anesthesia machine.

[0058] In this embodiment, the fluid collection device 200 can be made of various materials, such as polycarbonate or polypropylene, to ensure its transparency and durability. Specifically, the transparent bottle can be designed in a cylindrical or square shape for easy installation and removal. As a preferred embodiment, the fluid collection device 200 can be equipped with graduation markings to help medical personnel more accurately determine the amount of fluid collected. Furthermore, the fluid collection device 200 can be connected using threaded or snap-fit ​​connections for quick replacement and cleaning.

[0059] This application also provides an anesthesia machine (not shown), which includes a breathing circuit, a carbon dioxide absorber, and the aforementioned condenser; one of the air inlet 110 and the air outlet 120 is connected to the air inlet or air outlet of the breathing circuit; the other of the air inlet 110 and the air outlet 120 is connected to the air inlet or air outlet of the carbon dioxide absorber.

[0060] This application effectively solves the problem of condensation affecting the function of the breathing circuit during anesthesia by incorporating a condenser, a breathing circuit, and a carbon dioxide absorber. The condenser prevents condensation from accumulating in the breathing circuit by condensing water vapor into water and discharging it through the drain port 140. The condenser is connected to both the breathing circuit and the carbon dioxide absorber, ensuring smooth gas flow unaffected by condensation. The carbon dioxide absorber absorbs the carbon dioxide exhaled by the patient, reducing its accumulation in the breathing circuit. Therefore, the anesthesia machine effectively eliminates condensation, preventing its accumulation in the breathing circuit and ensuring its normal function, thus avoiding interference with the patient's breathing. Compared with existing technologies, the technical solution of this application does not require complex drainage procedures or constant temperature heating systems, reducing the manufacturing cost and maintenance difficulty of the anesthesia machine while improving its reliability and safety.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
