Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a soda lime pot and an anesthesia machine. Background Technology

[0002] In the clinical application of anesthesia machines, the soda lime container is a core component to ensure the safety of the breathing circuit. The soda lime (mainly calcium hydroxide, in granular form with a small amount of powder) inside continuously absorbs carbon dioxide in the patient's exhaled gas, preventing complications such as respiratory acidosis and hypoxia caused by carbon dioxide accumulation.

[0003] In actual use, soda lime reacts with carbon dioxide to produce calcium carbonate and water. Water vapor in the patient's exhaled breath easily forms condensation inside the canister. In addition, soda lime canisters are usually installed at the bottom of the circuit, which causes liquid to accumulate at the bottom of the canister. At the same time, the powder in the soda lime granules will settle to the bottom. Therefore, it is necessary to replace the soda lime regularly and clean the liquid and powder inside the canister.

[0004] Existing soda lime containers generally adopt a cylindrical structure, with the container body and lid connected by a screw-on buckle. Sealing is achieved by compressing the sealing ring with axial force during tightening. The drawbacks are: disassembly and assembly require gripping the container wall firmly with both hands and applying considerable force, making the operation cumbersome and laborious; the internal screen is connected to the container body using plastic clips, requiring special tools for disassembly and assembly, and these clips are prone to damage due to repeated deformation and aging, leading to increased maintenance costs.

[0006] To solve the above-mentioned technical problems, the present invention provides a soda lime container, comprising: a soda lime container body 1, a screen assembly 3, a soda lime container lid 5, a handle assembly 2, and fastening screws 4; wherein,

[0007] The handle assembly 2 includes a handle body 21 and a handle base 22; the handle body 21 extends along the axial direction of the soda lime can body 1 and is connected to the soda lime can body 1 through a plug-in structure for transmitting torque; the handle base 22 is located at the lower end of the handle body 21 and is used to support the bottom of the soda lime can body 1; the lower part of the handle base 22 is provided with a fastening screw mounting hole, the fastening screw mounting hole including an upper smooth hole 221 and a lower threaded hole 222;

[0008] The screen assembly 3 includes a screen body 31 and a screen connector 32; the screen body 31 is disposed inside the soda lime jar body 1 and is used to separate soda lime particles from the bottom space of the jar; the screen connector 32 is disposed inside the soda lime jar body 1 and is fixedly connected to the screen body 31, and the bottom of the screen connector 32 is provided with a threaded blind hole 321.

[0009] The fastening screw 4 passes through the threaded hole 222 and the light hole 221 in sequence, and then engages with the threaded blind hole 321 of the screen connector 32 to securely connect the screen assembly 3, the soda lime container body 1 and the handle assembly 2.

[0010] As an improvement to the aforementioned soda lime container, the body 1 of the soda lime container is a thin-walled cup-shaped structure made of transparent material, and its open end is connected to the soda lime container lid 5 through a spiral structure, with a first sealing ring provided at the connection.

[0011] As an improvement to the aforementioned soda lime container, the lower end of the handle base 22 is provided with an observation window 7.

[0012] As an improvement to the aforementioned soda lime container, a second sealing ring 6 is provided between the screen connector 32 and the soda lime container body 1.

[0026] The technical solution provided by this utility model is further illustrated below with reference to the embodiments.

[0027] Example 1

[0028] As shown in Figures 1(a) and 1(b), the soda lime container provided in this embodiment mainly consists of a soda lime container body 1, a handle assembly 2 (including a handle body 21 and a handle base 22), a screen assembly 3 (including a screen body 31 and a screen connector 32), fastening screws 4, a soda lime container lid 5, a first sealing ring, and a second sealing ring 6.

[0029] Sodium lime container body 1: A thin-walled cup-shaped structure made of transparent engineering plastic, used to hold sodium lime; Sodium lime container body 1 and sodium lime container lid 5 are connected by a spiral structure, and a first sealing ring is provided at the connection. The sealing is achieved by compressing the first sealing ring by the axial force generated by tightening the spiral.

[0030] The handle assembly 2 includes a handle body 21 and a handle base 22; the handle body 21 and the handle base 22 can be integrally formed; the handle body 21 extends along the axial direction of the soda lime container body 1, and the grip section is designed to conform to ergonomics, and is connected to the soda lime container body 1 through a plug-in structure to transmit torque; the handle base 22 is located at the lower end of the handle body 21 and is used to support the bottom of the soda lime container body 1; observation windows 7 are opened on both sides of the lower end of the handle base 22 to facilitate observation of the powder and liquid state at the bottom of the soda lime container body 1; the lower part of the handle base 22 is provided with fastening screw mounting holes, the upper part of the fastening screw mounting holes is a smooth hole 221 and the lower part is a threaded hole 222.

[0031] The sodium lime container body 1 and handle assembly 2 adopt a split design. In terms of remanufacturing, the mold and injection parameters can be optimized separately to avoid defects such as bubbles and shrinkage marks caused by differences in wall thickness, thereby improving the pass rate. The material selection is more flexible. The sodium lime container body 1 is made of corrosion-resistant and light-transmitting material, while the handle assembly 2 focuses on mechanical performance, reducing costs. During maintenance, aged or worn parts can be replaced individually without the need for complete scrapping. The assembly can compensate for errors through the plug-in structure, ensuring torque transmission, improving reliability, and better meeting the requirements of anesthesia machine circuit components.

[0032] Screen assembly 3: such as Figure 2 As shown, it consists of a screen body 31 and a screen connector 32; the screen body 31 has a mesh structure and is located inside the soda lime container body 1 to separate the soda lime particles from the bottom space of the container; the screen connector 32 has a cylindrical structure and is connected to the screen body 31, and its bottom is provided with a threaded blind hole 321; a second sealing ring 6 is provided between the screen connector 32 and the soda lime container body 1 to enhance the connection sealing.

[0033] Fastening screw 4: As shown in Figure 3(a), the end is a long rectangular structure, which is convenient for manual operation; as shown in Figure 3(b), the fastening screw 4 passes through the threaded hole 222 and the smooth hole 221 of the fastening screw mounting hole at the bottom of the handle base 22 in sequence, and then screws into the threaded blind hole 321 of the screen connector 32, thereby fastening the screen assembly 3, the soda lime container body 1 and the handle assembly 2 into one piece; since the upper part of the mounting hole is a smooth hole 221 and the lower part is a threaded hole 222, the fastening screw 4 remains in the handle assembly 2 after it is separated from the screen connector 32, which can prevent it from being lost.

[0034] Disassembly and assembly process:

[0035] Disassembling the container: Hold the handle body 21 and rotate the handle body 21 to separate the soda lime container body 1 from the soda lime container lid 5, thus completing the overall disassembly.

[0036] Cleaning and maintenance: Tighten the fastening screw 4 until it is disengaged from the screen connector 32. At this time, the screw remains in the light hole 221 of the handle assembly 2. After removing the screen assembly 3, the liquid and powder in the tank can be cleaned directly. After maintenance, reverse the operation to reset.

[0037] This utility model, through optimized structural design, achieves convenient operation and low maintenance cost of the soda lime container, is applicable to various anesthesia machine breathing circuit systems, and has high clinical application value.
