Description

Technical Field

[0001] This utility model belongs to the field of medical anesthesia technology, specifically relating to a concentration-adjustable anesthesia device. Background Technology

[0002] In the medical field, anesthetics used in anesthesiology are drugs that are frequently used to perform local or general anesthesia on patients. They are drugs that use drugs or non-drug methods to temporarily and reversibly lose sensation and pain in the body or a local area of ​​the body, and are mostly used for surgery or the treatment of certain diseases.

[0003] Because of differences in physical constitution among different individuals, the concentration of anesthetic needs to be precisely controlled before each injection. Medical staff sequentially retrieve anesthetic and diluent from the anesthetic storage unit and the diluent storage unit, controlling the concentration of the anesthetic by regulating the amount of anesthetic and diluent retrieved. However, after retrieving the anesthetic and diluent, it is also necessary to ensure that they are mixed evenly. Existing concentration-adjustable anesthesia devices mainly mix within a stirring tank, and the mixing effect within the delivery channel is generally poor, resulting in reduced mixing efficiency. Therefore, there is an urgent need for a concentration-adjustable anesthesia device. Utility Model Content

[0004] To address the problems existing in the background technology, this utility model provides a concentration-adjustable anesthesia device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A concentration-adjustable anesthesia device includes a diluent channel, one end of which is connected to an external diluent storage component, with a pump assembly between them. The other end of the diluent channel is fixedly connected to a stirring tank containing a stirring assembly. An anesthetic bottle is fixedly mounted on the diluent channel, with a movable cap on its top, connected to the external anesthetic storage component via a connecting pipe. A long rod is rotatably mounted within the diluent channel, with an impeller fixedly mounted on its outer surface. The top of the rod extends rotatably into the anesthetic bottle and is fixedly mounted on a turntable, the outer arc surface of which is sealed to the inner wall of the anesthetic bottle. The turntable has several leakage holes arranged in a circular array around its central axis, and an adjustment assembly for sealing the leakage holes is located within the turntable. A through-hole is located at the bottom of the anesthetic bottle, positioned on the trajectory of the leakage holes, and is connected to them via a transmission mechanism.

[0007] Furthermore, a hollow collector block is fixedly installed inside the diluent channel, with the hollow collector block facing the impeller and the through hole located above the hollow collector block.

[0008] Furthermore, the adjustment component includes a slide groove, with several slide grooves opened in the turntable. The slide grooves are arranged in a circular array around the central axis of the turntable. The number of slide grooves is equal to the number of leakage holes and they are connected one-to-one. Each slide groove is equipped with both a fixed electric push rod and a slidable sealing block. The telescopic shaft of the electric push rod is fixedly connected to the sealing block.

[0009] Furthermore, an inclined baffle is provided at the connection between the diluent channel and the mixing tank.

[0010] Furthermore, the stirring assembly includes a motor, a stirring rod is rotatably disposed inside the stirring tank, the motor is fixedly installed on the top of the stirring tank, and the output shaft of the motor extends rotatably into the stirring tank and is coaxially and fixedly connected to the top of the stirring rod.

[0011] Furthermore, a keyway is provided on the long rod, a key block is fixedly installed inside the turntable, and the long rod is key-connected to the turntable; a thread is fixedly provided on the top of the long rod, and a nut is threadedly connected to the thread.

[0012] This application has the following beneficial effects:

[0013] 1. When the diluent passes through the diluent channel, it drives the impeller to rotate, which in turn drives the turntable to rotate. By using the corresponding leakage holes on the turntable to match the through holes on the anesthetic bottle, the anesthetic is dripped into the diluent in an even and equal amount, thus ensuring uniform mixing of the anesthetic and the diluent and resulting in better actual use.

[0014] 2. This solution allows for adjustment of the actual number of leakage holes via an electric actuator, enabling the formulation of anesthetics of different concentrations according to actual needs, resulting in better practical effects.

[0015] 3. As the mixture enters the mixing tank from the diluent channel, it impacts the inclined baffle, causing the mixture to flow back and further improve the mixing effect.

[0016] 4. The motor can drive the stirring rod to rotate, further improving the mixing effect of the anesthetic and the diluent.

[0017] 5. This design allows the turntable to be disassembled by rotating the nut, facilitating cleaning and maintenance and further improving the practicality of the device. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] Example 1: As Figures 1-9 As shown, the technical solution adopted by this utility model is as follows: a concentration-adjustable anesthesia device includes a diluent channel 1, one end of the diluent channel 1 is connected to an external diluent storage component, and a pump assembly (not shown in the figure) is provided between the two, and a stirring tank 6 is fixedly connected to the other end of the diluent channel 1.

[0035] The pump assembly is used not only to transport the diluent from the external diluent storage assembly to the diluent channel 1, but also to ensure that the diluent flows within the diluent channel 1 at a certain flow rate (constant value) and flows into the mixing tank 6. Furthermore, both the external diluent storage assembly and the pump assembly are existing technologies and will not be described in detail in this solution.

[0036] An anesthetic bottle 2 is fixedly installed on the diluent channel 1. A cap 3 is detachably installed on the top of the anesthetic bottle 2. A connecting pipe 4 is connected to the top of the cap 3 and is connected to an external anesthetic storage component.

[0037] The cap 3 can be either snapped onto the top of the anesthetic bottle 2 or threaded onto the top of the anesthetic bottle 2; this solution does not limit this. Meanwhile, the external anesthetic storage component is prior art and will not be described in detail here.

[0038] A long rod 8 is rotatably installed in the diluent channel 1 along the vertical direction. An impeller 10 is fixedly installed on the outer surface of the long rod 8. The top of the long rod 8 extends rotatably into the anesthetic bottle 2 and a turntable 12 is fixedly installed therein. The outer arc surface of the turntable 12 is sealed to the inner wall of the anesthetic bottle 2.

[0039] A plurality of leakage holes 17 are provided on the turntable 12, and the plurality of leakage holes 17 are arranged in a circular array around the central axis of the turntable 12. Each leakage hole 17 is provided with an adjustment component, which can block the leakage hole 17. A through hole 11 is provided at the bottom of the anesthetic bottle 2, and the through hole 11 is located on the movement trajectory of the plurality of leakage holes 17, and the through hole 11 is connected to the leakage holes 17 in a transmission manner.

[0040] A hollow collector block 9 is fixedly installed inside the diluent channel 1. The shape of the hollow collector block 9 gradually narrows from the side of the external diluent storage component towards the mixing tank 6. For ease of description, the narrow end of the hollow collector block 9 is referred to as the output port. The output port of the hollow collector block 9 faces the impeller 10, and the through hole 11 is located above the output port of the hollow collector block 9.

[0041] The adjustment component includes a series of slides 19. Several slides 19 are formed within the turntable 12, arranged in a circular array around the central axis of the turntable 12. The number of slides 19 is equal to the number of leakage holes 17, and they are connected in a one-to-one correspondence. Each slide 19 contains both a fixedly mounted electric push rod 20 and a slidably positioned sealing block 21. The telescopic shaft of the electric push rod 20 is fixedly connected to the sealing block 21.

[0042] The telescopic shaft of the electric push rod 20 can drive the sealing block 21 to slide within the groove 19, thereby sealing the leakage hole 17. By adjusting the actual number of openings in the leakage hole 17, different concentrations of anesthetic can be prepared according to actual needs. (It should be noted that the open state of the leakage hole 17 is as follows...) Figure 6 As for Figure 9 As shown, it is only necessary to ensure that the angles between adjacent leakage holes 17 are equal, such as... Figure 5 The number of leaks shown is for illustrative purposes only; the number of leaks can be set to multiple.

[0043] A rotation damper (not shown in the figure) is provided at the rotatable connection between the long rod 8 and the bottom wall of the diluent channel 1 to ensure the uniform rotation of the long rod 8.

[0044] An inclined baffle 18 is provided at the connection between the diluent channel 1 and the mixing tank 6. The flow of the mixed liquid in the diluent channel 1 will impact the inclined baffle 18, thereby causing the mixed liquid to flow back and further improving the premixing effect of the two.

[0045] The mixing tank 6 is equipped with a mixing component.

[0046] The stirring assembly includes a motor 5, a stirring rod 7 rotatably disposed inside the stirring tank 6, a motor 5 fixedly mounted on the top of the stirring tank 6, and the output shaft of the motor 5 rotatably extending into the stirring tank 6 and being coaxially and fixedly connected to the top of the stirring rod 7.

[0047] Working principle of Example 1: During use, the pump assembly is activated, injecting the diluent from the external diluent storage assembly into the diluent channel 1. The diluent injected into the diluent channel 1 is then ejected through the collector hollow block 9. Due to the characteristic that the collector hollow block 9 gradually narrows from the external diluent storage assembly towards the mixing tank 6, the diluent ejected from the outlet of the collector hollow block 9 has a certain impact force. This impact force strikes the blades of the impeller 10, causing the blades to drive the long rod 8 to rotate on the bottom wall of the diluent channel 1. (Explanation: The pump assembly between the diluent channel 1 and the external diluent storage assembly can control the flow rate of the diluent through the outlet of the collector hollow block 9 to a constant value. Therefore, during the impact of the diluent on the impeller 10, the long rod 8 gradually reaches a state of uniform rotation.)

[0048] At the same time, the rotation of the long rod 8 will cause the turntable 12 to rotate at a constant speed inside the anesthetic bottle 2. The rotation of the turntable 12 can cause the leakage hole 17 on the turntable 12 to connect with the through hole 11 on the bottom wall of the anesthetic bottle 2 in sequence, so that the anesthetic in the anesthetic bottle 2 will drip intermittently into the diluent and mix, thereby improving the mixing effect of the anesthetic and the diluent.

[0049] The mixed anesthetic will impact the inclined baffle 18 as it flows into the mixing tank 6, causing the mixture to flow back, thereby further improving the premixing effect of the two.

[0050] During this period, motor 5 is started, which drives the stirring rod 7 to rotate, thereby further stirring the mixture in the mixing tank 6.

[0051] Additionally, the actual number of leak holes 17 opened can be adjusted according to the dosage of the anesthetic. Activating the electric push rod 20 pushes the sealing block 21 to slide within the groove 19 via its telescopic shaft, thereby sealing or releasing the leak holes 17. (Explanation: The open state of the leak holes 17 is as follows...) Figure 6 As for Figure 9 As shown, it is only necessary to ensure that the angles between adjacent leakage holes 17 are equal, such as... Figure 5 The number of leaks shown is for illustrative purposes only; the number of leaks can be set to multiple.

[0052] Example 2: Figures 10-12 As shown, the difference between this second embodiment and the first embodiment is that: a keyway 15 is formed on the long rod 8, a key block 16 is fixedly installed inside the turntable 12, and the long rod 8 and the turntable 12 are connected by a key. A thread 14 is fixedly installed on the top of the long rod 8, and a nut 13 is threadedly connected to the thread 14.

[0053] Working principle of embodiment 2: After removing the bottle cap 3, simply rotate the nut 13 to release the limit on the turntable 12, which facilitates cleaning and maintenance of the turntable 12 and further improves the practicality of the device.

[0054] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
