Traditional anesthesia devices often have deficiencies in anesthetic concentration control and anesthetic gas distribution uniformity, which may cause patients to feel uncomfortable during anesthesia. If the distribution method of anesthetic gas is not reasonable, it will also affect the patient's breathing smoothness, thereby reducing the comfort of anesthesia. Summary of the invention

[0016] Preferably, a staggered airflow mechanism is fixedly connected to the top of the base, and the staggered airflow mechanism includes a third bracket, and the third bracket is fixedly connected to the top of the base.

[0019] Compared with the related art, the anesthesia device with adjustable anesthetic concentration provided by the present invention has the following beneficial effects:

[0020] 1. The present invention provides an anesthesia device with adjustable anesthetic concentration. Through the coordinated work of the anesthesia mechanism and the guiding mechanism, the first motor is used to drive the second ring plate to rotate, which effectively avoids the problem of uneven anesthetic concentration in traditional anesthesia devices, so that the patient will not feel pain due to too shallow local anesthesia during the operation, nor will the risk of delayed awakening due to too deep local anesthesia increase, thereby improving the safety and effectiveness of anesthesia and ensuring the smooth progress of the operation.

[0021] 2. The present invention provides an anesthesia device with adjustable anesthetic concentration. The rotational motion of the guide mechanism and the setting of the staggered airflow mechanism significantly improve the distribution uniformity of the anesthetic gas. The two groups of staggered airflows generated by the staggered airflow mechanism further disrupt and evenly distribute the anesthetic gas, ensuring that the concentration of the anesthetic gas contacted by various parts of the patient's body is relatively stable and uniform, reducing the difference in anesthetic effect caused by uneven gas distribution, and improving the overall anesthesia quality.

[0022] 3. The present invention provides an anesthesia device with adjustable anesthetic concentration. The stable airflow generated by the staggered airflow mechanism flows toward the lying board, forming a good air circulation environment in the patient's breathing area, which helps the patient to maintain smooth breathing under anesthesia, avoids chest tightness, shortness of breath and other uncomfortable symptoms caused by accumulation of anesthetic gas or poor air circulation, makes the patient's breathing experience more comfortable during anesthesia, and reduces the anesthesia risks caused by respiratory problems, such as the probability of hypoxia.

[0023] 4. The present invention provides an anesthesia device with adjustable anesthetic concentration. Based on the feedback of the patient's vital signs monitoring data and the anesthesia depth monitoring situation, the key parameters such as the power of the anesthesia pump, the speed of the first motor and the second motor can be adjusted in real time. This dynamic control capability enables the anesthesia device to respond in time according to the individual differences of the patients and the changes in the surgical process, always providing the patient with the most suitable anesthesia state, further improving the comfort and safety of anesthesia, and meeting the diverse requirements of different surgical scenarios and patient needs.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] See also Figure 1-6 The present invention provides a technical solution: an anesthesia device with adjustable anesthesia concentration, comprising a base 1, a lying plate 2 is fixedly connected to the top of the base 1, a first ring plate 3 is fixedly connected to the top of the base 1, a guide mechanism 4 is fixedly connected to the top of the base 1, and an anesthesia mechanism 6 is fixedly connected to the top of the base 1;

[0036] When the anesthesia device is working, the anesthesia mechanism 6 starts to operate first. After the anesthesia pump 63 is started, the anesthetic in the anesthesia tank 61 is drawn out and pressurized under the action of its internal power, so that the anesthetic can flow along the spray pipe 64 and then sprayed into the space between the first ring plate 3 and the second ring plate 5 through the rubber tube 65 in the form of spray. The anesthesia pump 63 is provided with a concentration adjustment function to adjust the concentration of the sprayed anesthetic mist;

[0037] The guiding mechanism 4 comprises:

[0038] A fixing frame 43, the top of the fixing frame 43 is fixedly connected to the top of the base 1;

[0039] A first motor 41, the outer wall of the first motor 41 is fixedly connected to the outer wall of the fixing frame 43, and the outer wall of the first motor 41 is rotatably connected to the gear 42;

[0040] A guide bearing 44, the guide bearing 44 is rotatably connected to the outer wall of the fixing frame 43, the outer wall of the guide bearing 44 is movably connected to a guide ring 45, and the outer wall of the guide ring 45 is fixedly connected to the second ring plate 5;

[0041] A gear ring 46, the gear ring 46 is fixedly connected to the inner wall of the second ring plate 5, and the gear 42 is meshedly connected to the gear ring 46;

[0042] The guiding mechanism 4 works, the first motor 41 starts to run, and the power generated by the motor drives the gear 42 connected thereto to rotate. Since the gear 42 is meshed with the gear ring 46 fixed to the inner wall of the second ring plate 5, when the gear 42 rotates, the gear ring 46 will rotate accordingly, and the guiding bearing 44 is stuck in the guiding ring 45, limiting the rotation range of the guiding ring 45 and the second ring plate 5.

[0043] Embodiment 2:

[0044] See also Figure 1-7 As shown, based on the first embodiment, the present invention provides a technical solution:

[0045] In this embodiment, the anesthesia mechanism 6 includes a first bracket 62 , and the first bracket 62 is fixedly connected to the top of the base 1 .

[0046] In this embodiment, the top of the first bracket 62 is fixedly connected to an anesthesia tank 61 , and the top of the anesthesia tank 61 is fixedly connected to an anesthesia pump 63 .

[0047] In this embodiment, a spray tube 64 is fixedly connected to the outer wall of the anesthesia pump 63 , a rubber tube 65 is fixedly connected to the outer wall of the spray tube 64 , and the rubber tube 65 is arranged between the second ring plate 5 and the first ring plate 3 .

[0048] In this embodiment, the inner wall of the second ring plate 5 is fixedly connected with a transverse tube 66, and the inner wall of the second ring plate 5 is fixedly connected with a shielding block at the position of the transverse tube 66, and the shielding block shields the airflow of the transverse tube 66 at the position of the inner wall of the second ring plate 5. When the second ring plate 5 rotates, it drives the transverse tube 66 to rotate, and combines the Bernoulli principle;

[0049] During the rotation of the second ring plate 5, the transverse tube 66 fixedly connected to its inner wall also rotates together. According to Bernoulli's principle, when the transverse tube 66 rotates with the second ring plate 5, the air pressure around the transverse tube 66 will change due to the specific effect of the baffle block on the airflow. This change in air pressure will affect the anesthetic spray sprayed from the rubber tube 65, and change the airflow direction and distribution state of the spray. The transverse tube 66 is located in the second ring plate 5. Since the baffle block reduces the flow rate of the airflow, the airflow velocity at the bottom of the transverse tube 66 is large. Combined with Bernoulli's principle, the pressure is small. Under the pressure, the airflow is blown out through the transverse tube 66 onto the lying plate 2. By adjusting the rotation speed of the first motor 41, the rotation speed of the second ring plate 5 can be changed, thereby adjusting the distribution range and uniformity of the anesthetic concentration.

[0050] Embodiment three:

[0051] See also Figure 1-8 As shown, based on the first and second embodiments, the present invention provides a technical solution:

[0052] In this embodiment, a staggered airflow mechanism 7 is fixedly connected to the top of the base 1 . The staggered airflow mechanism 7 includes a third bracket 78 . The third bracket 78 is fixedly connected to the top of the base 1 .

[0053] In this embodiment, the outer wall of the third bracket 78 is fixedly connected to the fan 77, the top of the fan 77 is fixedly connected to the zigzag tube 76, the top of the zigzag tube 76 is fixedly connected to the airflow tube 74, the outer wall of the airflow tube 74 is provided with an airflow port 75, the outer wall of the lying board 2 is fixedly connected to the second bracket 71, the outer wall of the second bracket 71 is fixedly connected to the second motor 72, the outer wall of the second motor 72 is rotatably connected to the rotating rod 73, and the rotating rod 73 is fixedly connected to the outer wall of the airflow tube 74.

[0054] In this embodiment, the second bracket 71, the second motor 72, the airflow pipe 74, the airflow port 75, the rotating rod 73, and the zigzag pipe 76 are two groups, and are respectively fixed on both sides of the lying plate 2. The two second motors 72 are provided with control elements inside, and the airflow directions of the two airflow ports 75 are staggered.

[0055] When the fan 77 is started, an airflow is generated. The airflow flows along the inner channel of the zigzag tube 76 and enters the airflow of the airflow tube 74. When the second motor 72 rotates, the airflow tube 74 is driven to rotate around its axis through the rotating rod 73. Since a group of second motors 72, airflow tubes 74 and other components are respectively arranged on both sides of the lying plate 2, and the airflow directions of the two airflow ports 75 are staggered, when the two groups of airflow tubes 74 rotate at the same time and blow out airflows, these staggered airflows flow specifically toward the lying plate 2. The anesthetic gas distribution areas formed by the airflow field blend with each other. On the one hand, the staggered airflow can prevent the anesthetic gas from accumulating locally, and avoid the anesthetic effect and patient comfort being affected by the excessively high or low local anesthetic concentration. On the other hand, the stable airflow ensures the air circulation in the patient's breathing area, so that the patient can breathe smoothly during the anesthesia process, and reduces the discomfort caused by poor airflow, such as chest tightness, shortness of breath, etc.

[0056] During the entire operation, the power of the anesthesia pump 63, the speed of the first motor 41 and the second motor 72 and other parameters can be flexibly adjusted through the control unit according to the patient's vital signs monitoring data, such as heart rate, blood pressure, blood oxygen saturation, etc., as well as the anesthesia depth monitoring situation;

[0057] For example, when the patient's anesthesia depth is relatively shallow, the power of the anesthesia pump 63 can be appropriately increased to increase the output of the anesthetic. If it is found that the anesthetic gas concentration in a certain area is uneven and affects the anesthesia effect, the speed of the first motor 41 can be adjusted to improve it. If the patient shows signs of shortness of breath, the speed of the second motor 72 can be adjusted to change the intensity and distribution of the staggered airflow.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
