Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a concentration-adjustable anesthesia device for anesthesia departments. Background Art

[0002] In the clinical application of anesthesia, the concentration adjustment of anesthetic solution is a crucial step. Traditional anesthetic solution mixing equipment usually adopts a fixed container structure and sets a stirring mechanism inside the container to achieve the mixing of anesthetic solution.

[0003] However, this design has obvious limitations. For example, the patent document with patent publication number CN118767274A discloses a concentration-adjustable anesthesia device for anesthesiology, including a base, the upper surface of the base is fixedly connected to a stirring tank, the lower two sides of the stirring tank are connected to a delivery pipe, and the two support pipes are connected to the anesthesia tank and the dilution tank through a first connecting plate, a second connecting plate, and bolts. The present invention is provided with a third pressure plate, which can transport solid dirt to the stirring tank by pressure and then remove it, which can effectively avoid fixed dirt from clogging the inclined tube port and continue to maintain patency. During the reciprocating work, the third pressure plate scrapes off the attached dirt in the sealed space through the outer ring surface of the third pressure plate, which can automatically clean and prevent the liquid medicine from being contaminated, thereby improving practicality and functionality.

[0004] The anesthesia devices proposed in the above patent documents usually have the following problems in actual use: 1. Low mixing efficiency: The stirring structure in a fixed container often cannot ensure efficient mixing of the anesthetic solution. Especially when multiple anesthetic solution components need to be prepared, the problem of uneven mixing is particularly prominent.

[0005] 2. Difficulty in cleaning and maintenance: Since the mixing structure is located inside a fixed container, it is prone to scaling after long-term use, making it difficult to clean thoroughly. This not only affects the sanitation of the equipment, but also increases the difficulty and cost of maintenance.

[0006] In view of the above problems, the market is in urgent need of a new type of concentration-regulated anesthesia device for anesthesia department. The device should be able to efficiently and accurately mix anesthetic solutions of different concentrations while ensuring the easy cleaning and maintenance of the equipment, thereby improving the quality and safety of anesthetic solutions.

[0026] See also Figures 1-8 The present invention provides a technical solution: a concentration-adjustable anesthesia device for anesthesia department, which mainly includes core components such as a base plate 1, a support frame 2, a mixing mechanism 3 and an ultrasonic atomization component 4. The specific structure is as follows: The base plate 1 serves as the basic supporting structure of the entire device, and the support frame 2 is symmetrically arranged on the surface of the base plate 1 to fix and support other components.

[0028] It should be noted that the mixing tank 301 is rotatably mounted between the two support frames 2 and is used to mix anesthetic solutions of varying concentrations. Two position-limiting support tubes 327 are fixed to the left and right ends of the mixing tank 301 and rotatably connected to the support frames 2 via position-limiting shaft holes, ensuring stable rotation of the mixing tank 301.

A liquid inlet tube 328 is fixedly connected to the output end of the metering pump 306 and extends into the interior of the dosing cylinder 305 to deliver the metered anesthetic solution to the dosing cylinder 305.

[0037] The dose cylinder 305 is fixedly arranged on the side of the fixed plate 302 and used for temporarily storing the measured anesthetic liquid. The transparent scale plate 320 is fixedly arranged on the surface of the dose cylinder 305 and used for observing the amount of the anesthetic liquid.

[0038] The second liquid guide pipe 321 is fixedly arranged at the bottom end of the dose cylinder 305 and used for conveying the anesthetic liquid to the mixing tank 301. The second electromagnetic switch valve 322 is fixedly connected to the surface of the second liquid guide pipe 321 and used for controlling the flow of the anesthetic liquid.

[0039] The three-way connecting pipe 323 is fixedly connected to one end of the second liquid guide pipe 321 away from the dose cylinder 305 and fixedly connected to the third liquid guide pipe 324 and the L-shaped conveying pipe 326 at the other end. The third liquid guide pipe 324 is used for conveying the anesthetic liquid to the ultrasonic atomization assembly 4 for atomization treatment, and the surface of the third liquid guide pipe 324 is fixedly connected with the third electromagnetic switch valve 325. The bottom end of the L-shaped conveying pipe 326 extends into the mixing tank 301 and is used for directly conveying the anesthetic liquid to the mixing tank 301 for mixing.

[0040] It is worth noting that the ultrasonic atomization assembly 4 includes an ultrasonic atomization box 401, an ultrasonic wave generator 402, a filter box 5, etc., and is used for atomization and filtration of the anesthetic liquid. The ultrasonic atomization box 401 is fixedly connected to the surface of the bottom plate 1 and used for accommodating the ultrasonic wave generator 402 and performing atomization treatment of the anesthetic liquid.

[0042] The atomized liquid guide pipe 403 is fixedly arranged on the upper surface of the ultrasonic atomization box 401, extends into the ultrasonic atomization box 401 at one end, and extends into the filter box 5 at the other end, and is used for conveying the atomized anesthetic liquid to the filter box 5.

[0043] The anesthetic atomization pipe 9 is fixedly arranged on the back of the filter box 5 and used for outputting the filtered anesthetic liquid. The atomization flow control valve 7 is fixedly arranged on the surface of the anesthetic atomization pipe 9 and used for controlling the output flow of the anesthetic liquid.

[0044] Working Principle: When using the concentration-regulated anesthesia device for anesthesia provided by the present invention, first, the metering pump 306 accurately measures anesthetic solutions of varying concentrations and delivers the solutions to the dosing cylinder 305 for temporary storage. Subsequently, based on the anesthesia requirements, the second electromagnetic on / off valve 322 is controlled to control the on / off state of the solution, allowing the solution to be delivered to the mixing tank 301 for mixing via the second liquid conduit 321, the three-way connecting tube 323, and the L-shaped delivery tube 326, or directly delivered to the ultrasonic atomization assembly 4 for atomization via the second liquid conduit 321, the three-way connecting tube 323, and the third liquid conduit 324.

[0045] In mixing tank 301, drive motor 308 drives solution preparation tank 304 and mixing tank 301 to rotate simultaneously, achieving efficient mixing of the anesthetic solution and diluent. The mixed anesthetic solution is then transported back to mixing tank 301 via L-shaped delivery tube 326 for further mixing until the desired concentration is reached.

[0046] Anesthetic liquid that requires atomization is delivered to the ultrasonic atomization box 401 via the third liquid conduit 324, where it is atomized by ultrasonic waves generated by an ultrasonic generator 402. The atomized anesthetic liquid is delivered to the filter box 5 via the atomized liquid conduit 403. After being filtered by the impurity removal filter 6, it is output from the anesthesia atomization tube 9 for use. The output flow rate of the anesthetic liquid can be adjusted by the atomization flow control valve 7 to meet different anesthesia requirements.

[0047] The concentration-regulated anesthesia device for anesthesiology of the present invention utilizes a rotary drum structure, eliminating the problem of scaling of the stirring mechanism within a fixed container. After extended use, components such as the mixing tank 301 and the solution preparation tank 304 require simple disassembly and cleaning to maintain the cleanliness and ease of maintenance of the device. Furthermore, the filter cartridge 5 and impurity removal filter 6 within the ultrasonic atomization assembly 4 are also easily disassembled and replaced, ensuring the purity of the anesthetic solution and the atomization effect.
