Description

Technical Field

[0001] This utility model belongs to the field of medical equipment for laryngeal anesthesia, and in particular relates to a laryngeal anesthesia device. Background Technology

[0002] Before performing surgery or bronchoscopy on a patient's throat, anesthesia must first be administered to the affected area to reduce pain. Modern medical methods of laryngeal anesthesia include transcraniotomy or lateral injection of anesthetic agents into the neck. However, these methods are not only highly invasive but also unacceptable to many patients. Therefore, a safe, minimally invasive, and efficient anesthesia method is what modern medicine has been striving for.

[0003] Chinese Patent Publication No. CN220656120U discloses a laryngeal anesthetic spray device, comprising a bottle, a power supply system, a power source, a liquid reservoir, a miniature water pump, a suction tube, an outlet tube, a flexible hose, and a spray head. The device works by powering the miniature water pump, which then draws liquid from the bottle through the suction tube. The liquid flows from the outlet tube to the spray head on the hose, and then reaches the patient's throat in mist form. While this method of atomizing the anesthetic and spraying it directly onto the patient's throat is relatively safe and harmless, the anesthetic mist is expelled through the spray head. Since the diameter of a patient's throat varies, a single-diameter hose cannot evenly spray the mist onto throats of different diameters, potentially leading to prolonged anesthesia and excessive anesthetic dosage.

[0004] In summary, the existing laryngeal anesthesia devices have the following problems: they cannot be adapted to medical tubing of different diameters and have poor adaptability to working environments. Utility Model Content

[0046] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0047] Please see Figures 1 to 6 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0048] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0049] In this embodiment, please refer to Figures 1 to 2 This utility model provides a laryngeal anesthesia device, which includes:

[0050] The anesthetic nebulizer body 6 has a spray nozzle 601 for spraying out mist.

[0051] Mounting cover 1 is installed at the spray nozzle 601 of the anesthetic nebulizer body 6;

[0052] Here, the connection method of the mounting cover 1 at the spray nozzle 601 of the anesthetic nebulizer body 6 is not limited; it can be connected by threads or by snap-fit.

[0053] Several hose connectors 2, the hose connectors are annular tubular structures, the hose connectors are connected sequentially from the inside to the outside, the innermost hose connector is fixedly installed on the mounting cover 1, and the innermost hose connector passes through the mounting cover 1 and communicates with the inside of the mounting cover 1.

[0054] In this example, only two hose connectors are selected. The hose connector connected to the mounting cover is the innermost hose connector, which is the first connector 201. The hose connector connected to the innermost hose connector is the outermost hose connector, which is the second connector 202.

[0055] Here, the hose connectors are connected in a multi-layer nested pattern. Taking the innermost hose connector as the base point, hose connectors of different diameters can be sequentially connected outwards. This method changes the diameter of the hose connectors that are matched with the medical hose 4 by adding different numbers of hose connectors.

[0056] Here, the first pipe connector 201 is integrated with the mounting cover 1, and the interior of the first pipe connector 201 penetrates and communicates with the mounting cover 1, ensuring that the mist is transferred out of the mounting cover 1.

[0057] Medical tubing, wherein the medical tubing 4 is inserted into the outer wall of the outermost tubing connector;

[0058] Here, the medical hose 4 is inserted into the outer wall of the outermost hose connector in an interference fit, ensuring the tightness and airtightness of the connection of the medical hose 4.

[0059] In this embodiment, please refer to Figures 2 to 4 The innermost hose connector has an external thread at the bottom of its outer wall, while the bottom of the inner and outer walls of the other hose connectors have threads. Adjacent hose connectors are connected by threads.

[0060] Here, the hose connector can be selected by sequentially connecting the bottom threads to select a hose connector of appropriate diameter; in this example, the first hose connector 201 is provided with a first external thread 2011 at the bottom; the second hose connector 202 is provided with a first internal thread 2021 on the inner side of the bottom; the second hose connector 202 is provided with a second external thread 2022 on the outer side of the bottom, and the second hose connector 202 is fitted onto the first hose connector 201 and locked by the first internal thread 2021 and the first external thread 2011.

[0061] This threaded fixing method allows for the sequential connection of various hose connectors of different diameters. Doctors can pre-insert the selected medical hose 4 onto the hose connector of the appropriate diameter and then sequentially connect other hose connectors, making it easier for doctors to disassemble and replace the medical hose 4.

[0062] In this embodiment, please refer to Figure 5 The medical hose 4 has one blind end and the other end inserted into the outer wall of the outermost hose connector. The blind end of the medical hose is provided with a first vent 401, and the front end of the medical hose has a plurality of second vents 402 arranged in a circular array.

[0063] Here, the material of the medical tubing 4 is not limited; it can be silicone.

[0064] The doctor can deliver medication from the bottom and remove waste liquid through the first air outlet 401 at the blind end of the medical hose 4. The second air outlets 402, which are arranged in a circular array at the front end of the medical hose 4, can make the medication spray more evenly in the throat.

[0065] In this embodiment, please refer to Figure 5 The laryngeal anesthesia device also includes a malleable guidewire 5;

[0066] The side wall of the mounting cover 1 has a through hole 101. One end of the malleable guide wire 5 passes through the innermost hose connector to reach the inside of the medical hose 4, and the other end of the malleable guide wire 5 extends outward through the through hole 101.

[0067] In this example, the first pipe connector 201 is provided with a guide post 3 inside. The guide post 3 is cylindrical and has a circular hollow channel in the center. The axis of the circular hollow channel coincides with the axis of the first pipe connector 201. The inner diameter of the guide post 3 is larger than the diameter of the malleable guide wire 5. The side wall of the mounting cover 1 is provided with a through hole 101. One end of the malleable guide wire 5 passes through the guide post 3 to reach the inside of the medical tubing 4, and the other end of the malleable guide wire 5 extends outward through the through hole 101.

[0068] Here, the structural form of the guide post 3 and the innermost hose connector is not limited. The outer wall of the guide post 3 and the inner wall of the innermost hose connector are connected by a connecting rib. The guide post, the connecting rib and the innermost hose connector are integrally formed.

[0069] One end of the malleable guidewire 5 passes through the guide post 3 and enters the inside of the medical tubing 4, while the other end extends to the outside through the through hole 101. This allows the medical tubing 4 to be shaped by the malleable guidewire 5, which can effectively reduce the patient's pain caused by throat discomfort.

[0070] An inner sealing plug 501 and an outer sealing plug 502 are fixedly installed on the malleable guide wire 5. The inner sealing plug 501 is located inside the mounting cover 1, and the outer sealing plug 502 is located outside the mounting cover 1. The inner sealing plug 501 can be inserted into the inside of the through hole 101 and seal it, and the outer sealing plug 502 can be inserted into the outside of the through hole 101 and seal it. The distance between the inner sealing plug 501 and the outer sealing plug 502 is greater than the length of the through hole 101.

[0071] Here, the inner sealing plug 501 and the outer sealing plug 502 are conical. The conical direction of the inner sealing plug 501 extends out of one end of the mounting cover 1 towards the malleable guide wire 5. The conical direction of the outer sealing plug 502 is inserted into one end of the medical tubing 4 towards the malleable guide wire 5. The inner shape and size of the through hole 101 match the inner sealing plug 501, and the outer shape and size of the through hole 101 match the outer sealing plug 502.

[0072] During the process of pulling the malleable guide wire 5, the inner sealing plug 501 and the outer sealing plug 502 will block the inner and outer sides of the through hole 101 to achieve the function of limiting and sealing the malleable guide wire 5.

[0073] In this embodiment, please refer to Figure 5 The end of the malleable guidewire 5 inside the medical hose 4 is a sphere, the diameter of which is larger than the diameter of the first air outlet 401 and smaller than the inner diameter of the medical hose 4. The end of the malleable guidewire 5 outside the mounting cover 1 is also a sphere.

[0074] Here, the end ball of the malleable guidewire 5 inside the medical tubing 4 is the top ball 503, and the end ball of the malleable guidewire outside the mounting cover 1 is the end ball 504.

[0075] Here, the diameter of the tip ball 503 is smaller than the inner diameter of the medical tube 4 and larger than the diameter of the first air outlet 401, so the tip ball 503 can block the first air outlet 401.

[0076] Here, the material of the malleable guide wire 5 is not limited and can be aluminum wire;

[0077] By selectively blocking the first air outlet 401, doctors can choose to administer medication to different sites in different situations.

[0078] In this embodiment, please refer to Figure 6 The anesthetic nebulizer body 6 includes a nebulizer generator 603 and a nebulizer adapter 602;

[0079] The atomizer 6 is provided with an air outlet 606.

[0080] In this embodiment, the atomization principle of the atomizing generator 603 is the same as that of common humidifiers on the market. The atomization principle is as follows: using high-frequency oscillation of ultrasound, liquid medicine or water is broken into tiny particles to form a mist. An ultrasonic atomizing generator typically consists of an ultrasonic transducer and an atomizing plate (not illustrated in the accompanying drawings of this embodiment). The ultrasonic transducer converts electrical energy into ultrasonic energy, while the atomizing plate atomizes the liquid medicine or water into tiny particles.

[0081] The advantage of atomizing via ultrasound is that it involves less vibration and more stable atomization, which can reduce the pain caused by vibration of the medical tubing for patients.

[0082] The air outlet 606 and the atomizer 603 are integrated into one structure, and the mist generated by the mist generator 603 will be discharged from the air outlet 606.

[0083] One end of the atomizer adapter 602 is mounted on the atomizer generator 603, and the other end of the atomizer adapter 602 is connected to the mounting cover 1;

[0084] Here, the connection method between the atomizer adapter 602 and the atomizer generator 603 is not limited; it can be a threaded connection or a snap-fit ​​connection.

[0085] In this embodiment, please refer to Figure 6 The atomizer adapter 602 has an S-shaped groove 6021 inside. The two ends of the S-shaped groove 6021 are respectively connected to the two end faces of the atomizer adapter 602. One end of the S-shaped groove 6021 is connected to the air outlet 606 of the atomizer generator 603, and the other end of the S-shaped groove 6021 is the spray nozzle 601.

[0086] Here, because the nebulized medication fills the medical tubing 4, water droplets or liquid will condense on the inner wall of the medical tubing 4 after a period of time. In addition, liquid from the patient's throat may also flow into the medical tubing 4 from the first air outlet 401 or the second air outlet 402. The S-shaped groove 6021 inside the nebulizer adapter 602 will allow the liquid to remain at the lower bend of the S-shaped groove 6021 due to gravity, which can prevent the backflow of the nebulized liquid or the liquid at the front end of the medical tubing 4. The S-shaped groove 6021 reduces the maintenance cost of the laryngeal anesthesia device and improves the safety and hygiene of the laryngeal anesthesia device.

[0087] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 6 The laryngeal anesthesia device also includes: a lower clamp 10, a guide rod 8, a limiting block 7, a spring 9, and a medicine bottle 11;

[0088] The anesthetic nebulizer body 6 also includes a base 604 and an inlet pipe 605, wherein the base 604 is fixedly installed below the nebulizer generator 603;

[0089] Here, the connection between the atomizer generator 603 and the base 604 is not fixed; it can be designed as an integral unit or a threaded connection can be used.

[0090] A guide hole 6041 is provided through the bottom 604, and the lower end of the guide rod 8 passes through the guide hole 6041 and is fixedly connected to the lower clamping plate 10.

[0091] Here, the connection method between the guide rod 8 and the lower clamping plate 10 is not limited; they can be welded together or connected by threads.

[0092] The guide rod 8 is slidably connected to the guide hole 6041, and the sliding direction of the guide rod 8 is perpendicular to the bottom surface of the base 604;

[0093] The limiting block 7 is fixedly installed on the top of the guide rod 8;

[0094] Here, the connection method between the limiting block 7 and the guide rod 8 is not limited; it can be integral welding or threaded connection.

[0095] The spring 9 is sleeved on the guide rod 8, one end of the spring 9 abuts against the limiting block 7, and the other end of the spring 9 abuts against the upper surface of the base 604;

[0096] Here, when the medicine bottle 11 is placed between the lower clamping plate 10 and the bottom end face of the base 604, the distance between the lower clamping plate 10 and the bottom end face of the base 604 becomes longer, thereby shortening the distance between the limiting block 7 and the base 604. The limiting block 7 compresses the spring 9, and the spring 9 generates an upward force after deformation.

[0097] The upward force generated by the deformation of spring 9 causes the lower clamp 10 to clamp the medicine bottle 11, which makes the operation more convenient for doctors.

[0098] The medicine bottle 11 is clamped between the lower clamping plate 10 and the bottom end face of the base 604, and the liquid inlet tube 605 is inserted into the medicine bottle 11;

[0099] Here, the nebulizer 603 also includes a water pump (this technical feature is not illustrated in the accompanying drawings). The inlet pipe 605 is connected to the water pump inside the nebulizer 603. The water pump draws the drug liquid through the inlet pipe 605 and delivers it to the nebulizing plate, thereby nebulizing the anesthetic drug liquid.

[0100] The specific usage of this embodiment is as follows:

[0101] In use, first pull down the lower clamp 10, place the medicine bottle 11 on the lower clamp 10 and align the medicine bottle 11 with the inlet tube 605. After releasing the lower clamp 10, the lower clamp 10 will automatically clamp the medicine bottle 11. Then, according to the patient's age and gender or different anesthesia positions, the doctor selects the outermost tubing connector 2 of appropriate diameter and connects the other tubing connectors in sequence until it is installed on the mounting cover 1. In advance, use the top ball 503 on the malleable guide wire 5 to press against the first air outlet 401 on the medical tubing 4 and use the malleable guide wire 5 to shape the medical tubing 4. Then, insert the medical tubing 4 into the throat of the patient to be anesthetized, and start the nebulizer 603. The nebulizer 603 starts to work. The water pump inside the nebulizer 603 draws liquid from the medicine bottle 11 through the inlet tube 605 and delivers it to the nebulizer plate for nebulization. The nebulized gas is evenly sprayed onto the patient's throat through the second air outlet 402 on the medical tubing 4.

[0102] Meanwhile, if you want to open the first vent 401 due to different working conditions or to drain the liquid from the medical tubing 4, you can hold the end ball 504 of the malleable guidewire 5 and pull the malleable guidewire 5 outward until the inner sealing plug 501 on the malleable guidewire 5 is inserted into the inside of the through hole 101 on the mounting cover 1, thereby opening the first vent 401 on the medical tubing 4.

[0103] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
