Description

Technical Field

[0001] This application relates to the field of anesthesia technology, and in particular to an anesthetic agent concentration regulating device. Background Technology

[0002] In modern medicine, the use of anesthetics is an indispensable part of the surgical procedure. Anesthetics effectively reduce the patient's pain and ensure the smooth progress of the surgery. Different concentrations of anesthetics are prepared using anesthetic concentration adjustment devices.

[0003] A utility model patent with publication number CN215460230U discloses a concentration-adjustable anesthesia device for anesthesiology departments. High-concentration anesthetic and diluted anesthetic liquid are mixed in a mixing chamber to produce anesthetics of different concentrations. However, when producing anesthetics of different concentrations, anesthetic residue may remain in the mixing chamber, leading to inaccurate concentrations of the produced anesthetics. Furthermore, because the mixing chamber is not easily disassembled from the base plate, cleaning the mixing chamber is inconvenient. Utility Model Content

[0004] The purpose of this application is to provide an anesthetic concentration adjustment device that facilitates the disassembly of the mixing tube and the cleaning of the mixing tube.

[0005] The anesthetic concentration regulating device provided in this application adopts the following technical solution:

[0017] Optionally, the first sleeve includes an insertion section and a connecting section. The outer diameter of the insertion section is smaller than that of the connecting section. The insertion section is adapted to the mixing tube and can be inserted into the mixing tube. The connecting section abuts against the mixing tube.

[0018] The outer wall of the insertion section is fixedly connected with a protruding rib, and the inner wall of the mixing tube is provided with an annular groove. The protruding rib is disposed in the annular groove and can slide in the annular groove.

[0019] Optionally, a second elastic ring is fixedly connected to the lower end of the mixing tube, a slot is provided on the turntable, and a second slot is provided on the inner wall of the slot, so that the mixing tube can be inserted into the slot and the second elastic ring can be engaged in the second slot.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0032] A device for adjusting the concentration of an anesthetic agent, as described above. Figure 1 and Figure 2 The system includes a base 1, a turntable 2, a mixing tube 3, a piston 4, a stock solution tank 5, a dilution tank 6, and a solenoid valve 7. The turntable 2 is rotatably mounted on the base 1, and in this embodiment, the turntable 2 is driven to rotate by a motor. The mixing tube 3 has an open upper end and is detachably connected to the turntable 2, allowing it to rotate with the turntable 2. When a specific concentration of anesthetic needs to be prepared, a fixed amount of anesthetic stock solution and diluent are injected into the mixing tube 3 through the stock solution tank 5, the dilution tank 6, and the mixing tube 3. The reciprocating rotation of the turntable 2 then achieves uniform mixing of the anesthetic stock solution and diluent, thereby obtaining an anesthetic of the specified concentration.

[0033] Specifically, a mounting bracket 11 is fixedly connected to the base 1. The stock solution tank 5 and the dilution tank 6 are fixed on the mounting bracket 11 and located above the mixing tube 3. The piston 4 is rotatably mounted on the mixing tube 3 and is used to seal the opening of the mixing tube 3. Both the stock solution tank 5 and the dilution tank 6 are connected to the mixing tube 3 through pipes 8. The pipes 8 are inserted into and pass through the piston 4, thereby achieving communication with the mixing tube 3. During the rotation of the mixing tube 3, the piston 4, due to its rotatable connection with the mixing tube 3, does not rotate with the mixing tube 3, reducing the possibility of the pipes 8 becoming tangled or knotted.

[0034] The aforementioned solenoid valves 7 are installed between the stock solution tank 5 and the piston 4, and between the dilution tank 6 and the piston 4. These solenoid valves 7 control the flow between the stock solution tank 5 and the mixing tube 3, and between the dilution tank 6 and the mixing tube 3, thereby enabling the quantitative injection of the anesthetic stock solution and diluent into the mixing tube 3. In other embodiments, flow meters can be installed on the stock solution tank 5 and the dilution tank 6 to precisely control the amount of anesthetic stock solution and diluent injected into the mixing tube 3.

[0035] Reference Figure 2 and Figure 3 Specifically, a first sleeve 31 is rotatably connected to the opening of the mixing pipe 3. A piston 4 is engaged with the first sleeve 31 to close the first sleeve 31, thereby sealing the mixing pipe 3. The piston 4 and the mixing pipe 3 are detachably connected through the detachable connection between the piston 4 and the first sleeve 31. During the rotation of the mixing pipe 3, the first sleeve 31 does not rotate with the mixing pipe 3, thus the piston 4 also does not rotate with the mixing pipe 3, reducing the risk of tangling and knotting in the pipe 8.

[0036] Reference Figure 2 and Figure 4 The first sleeve 31 includes an insertion section 311 and a connecting section 312. The outer surface of the insertion section 311 is smaller than that of the connecting section 312. The insertion section 311 is adapted to the mixing tube 3 and can be inserted into the mixing tube 3. The connecting section 312 abuts against the mixing tube 3 to ensure the installation stability of the first sleeve 31. A protruding rib 313 is fixedly connected to the outer wall of the insertion section 311. An annular groove 314 is formed on the inner wall of the mixing tube 3. The protruding rib 313 is disposed in the annular groove 314 and can slide within the annular groove 314 to limit the rotation path of the first sleeve 31 and ensure the rotational stability of the first sleeve 31. By setting the first sleeve 31, it is ensured that the piston 4 can be detachably connected to the mixing tube 3 while also being stably rotatably connected to the mixing tube 3.

[0037] Furthermore, a first groove 315 is provided on the inner wall of the first sleeve 31, and a first elastic ring 41 is fixedly connected to the outer wall of the piston 4. The first elastic element 41 can be inserted into the first groove 315. Through the cooperation between the first elastic ring 41 and the first groove 315, the piston 4 and the first sleeve 31 can be detachably connected.

[0038] Furthermore, a handle 42 is fixedly connected to the piston 4. By setting the handle 42, the piston 4 can be pulled out through the handle 42 when it is necessary to disassemble it, which is convenient for the user to operate.

[0039] Furthermore, a second elastic ring 32 is fixedly connected to the lower end of the mixing tube 3. A slot 21 is provided on the turntable 2, and a second groove 22 is provided on the inner wall of the slot 21. The mixing tube 3 can be inserted into the slot 21, and the second elastic ring 32 can be engaged in the second groove 22. Through the cooperation of the second elastic element and the second groove 22, the mixing tube 3 and the turntable 2 are detachably connected. During the rotation of the turntable 2, the mixing tube 3 can be driven to rotate together. When it is necessary to disassemble and clean the mixing tube 3, the piston 4 can be pulled off, and the mixing tube 3 can be pulled out of the turntable 2.

[0040] Reference Figure 2 and Figure 5 Furthermore, a second sleeve 33 is rotatably fitted onto the upper end of the mixing tube 3. A third slot 331 is formed on the outer wall of the second sleeve 33. A bracket 12 is slidably mounted on the base 1, and a limiting ring 13 is fixedly connected to the bracket 12. The limiting ring 13 can be inserted into the third slot 331. Through the cooperation of the limiting ring 13 and the third slot 331, the upper end of the mixing tube 3 is limited, ensuring the installation stability of the mixing tube 3 and ensuring that the mixing tube 3 will not separate from the turntable 2 during rotation. In this embodiment, an abutment ring 16 can be provided at the upper end of the bracket 12. The abutment ring 16 abuts against the first sleeve 31, thereby limiting the rotation of the first sleeve 31 and further reducing the situation where the first sleeve 31 rotates with the mixing tube 3.

[0041] Reference Figure 6 Furthermore, a fixing block 14 is fixedly connected to the side wall of the bracket 12, and a fixing member 15 is provided on the fixing block 14. The fixing member 15 can penetrate the fixing block 14 and is fixed to the base 1. In this embodiment, the fixing member 15 is a bolt, which connects the fixing block 14 and the base 1 to restrict the sliding of the bracket 12, so as to ensure the fixation of the upper end of the mixing pipe 3 and ensure the installation stability of the mixing pipe 3.

[0042] When it is necessary to disassemble and clean the mixing tube 3, loosen the fixing part 15, then slide the bracket 12 to separate the limiting ring 13 from the third slot 331, then remove the piston 4 from the mixing tube 3 and remove the mixing tube 3 from the turntable 2.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
