Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a spray device for airway surface anesthesia during endotracheal intubation. Background Technology

[0002] In clinical practice, local anesthesia of the larynx is required when performing laryngoscopy, endotracheal intubation, or laryngeal surgery. Currently, laryngeal nebulizers are commonly used to deliver medication directly to the larynx and upper respiratory tract in a spray form. Existing laryngeal nebulizers typically consist of a cuff, tubing, medication bottle, nozzle, and spray nozzle. When used, pressing the cuff allows the medication in the bottle to enter the nozzle and be sprayed out through the nozzle. This type of laryngeal nebulizer has several problems in its use:

[0003] Firstly, the nozzle is usually made of metal, which lacks flexibility and cannot be adjusted to fit the shape of the patient's throat, making it impossible to deliver medication to deeper parts of the throat.

[0004] Secondly, the drug administration is inaccurate. The manual compression of the balloon leads to inconsistent dosages among different doctors (different compression frequencies and pressures will cause variations in dosage). Since anesthetics cannot be overdosed, inaccurate dosage may cause local anesthetic poisoning in patients.

[0005] Thirdly, there is a lack of visualization tools. Doctors need to use a video laryngoscope to observe the insertion position of the laryngeal spray nozzle in order to accurately locate the glottis and administer anesthesia. This operation is difficult and irritating, resulting in poor patient comfort and acceptance. Utility Model Content

[0006] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a spray device for airway surface anesthesia during endotracheal intubation, so as to achieve the purpose of quantitative, directional, and precise drug delivery.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a spray device for airway surface anesthesia during endotracheal intubation, comprising a housing and a pump system, a power supply system and a control system assembled in the housing, wherein the pump system is electrically connected to the power supply system through the control system;

[0008] It also includes a liquid dispensing system mounted on the housing; the liquid dispensing system includes a liquid dispensing pipe and a liquid storage bottle mounted on the housing, and a spray head mounted at the front end of the liquid dispensing pipe; the liquid dispensing pipe is connected to the liquid storage bottle through a pump system;

[0009] It also includes a visualization system, which includes an imaging lens installed at the front end of the liquid outlet tube and a first optical fiber laid in the liquid outlet tube; the control system is equipped with a WiFi module for communication with external devices and an image sensor for processing light signals into electrical signals; the imaging lens is connected to the image sensor through the first optical fiber to realize the transmission of light signals.

[0010] As a limitation of this utility model, the visualization system also includes a cold light source disposed inside the housing and a second optical fiber arranged in the liquid outlet pipe; the cold light source is electrically connected to the power supply system through the control system; the cold light source is connected to the second optical fiber to guide the light to the front end of the liquid outlet pipe.

[0011] As another limitation of this utility model, the liquid outlet tube is a malleable flexible tube.

[0012] As a further limitation of this utility model, the pore size of the micropores on the spray head is less than 0.2 mm.

[0013] As a further limitation of this utility model, the spray head is a piezoelectric spray head, which is electrically connected to the power supply system through a control system.

[0014] As another limitation of this utility model, the power system includes a rechargeable battery and a switch button and a charging port connected to the rechargeable battery through a control system, both of which are located on the housing.

[0015] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0016] (1) This utility model achieves precise quantitative drug administration by introducing a pump system and a control system, which can effectively avoid local anesthetic poisoning caused by excessive drug dosage and improve the safety of laryngeal anesthesia. Specifically, the pump system is used for liquid dispensing control to ensure that the amount of drug sprayed per second is consistent; the control system is used to set the single working time of the pump system, thereby achieving precise quantitative drug administration.

[0017] (2) By introducing a visualization system to display the larynx image in real time, this utility model can provide doctors with an operational field of view, enabling doctors to accurately deliver the spray head to the target position to implement anesthesia, effectively improving the convenience of clinical operation.

[0018] (3) The liquid outlet tube in this utility model is a malleable flexible tube, which can be arbitrarily shaped according to the doctor's needs to adapt to the shape of the oral cavity and throat, so as to better reach the target position.

[0019] (4) The spray head in this utility model adopts a structure that can better refine the medicine liquid (such as a piezoelectric spray head or a spray head with a micropore diameter of less than 0.2 mm), so that the medicine liquid can be evenly attached to the throat mucosa, avoiding the medicine liquid from flowing down in the form of water droplets, which not only avoids wasting the medicine liquid, but also improves the drug administration effect.

[0020] In summary, this invention improves the safety and effectiveness of laryngeal anesthesia, enhances the convenience of clinical operation, and improves patient comfort and tolerance. It is suitable for use when performing endotracheal intubation, laryngoscopy, or laryngeal surgery, and can provide patients with a safer and more precise treatment experience.

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0027] This embodiment discloses a spray device for airway surface anesthesia during endotracheal intubation, including a housing 1, a pump system, a power supply system, a control system, a liquid dispensing system, and a visualization system.

[0028] like Figures 1 to 2 As shown, the housing 1 has a gun-shaped structure, including a gun barrel 2 and a grip 3.

[0029] The pump system is used to pump the drug solution in a metered manner. The pump system is encapsulated in the housing 1 and the gun barrel 2. In this embodiment, a miniature peristaltic pump in the prior art is used. The miniature peristaltic pump is electrically connected to the power system through the control system.

[0030] The power system provides power to the pump system, control system, and visualization system. The power system includes a rechargeable battery encapsulated in the gun barrel portion 2 of the housing 1, a switch button 4 electrically connected to the rechargeable battery via the control system, and a charging port. The switch button 4 is located at the tail end of the gun barrel portion 2 of the housing 1, and can control the opening or closing of this embodiment. The charging port is located on the side wall of the gun barrel portion 2 of the housing 1, and can be used to charge the rechargeable battery; in this embodiment, the charging port is a Type-C charging port.

[0031] The control system is a PCB board encapsulated within the gun barrel section 2 of the housing 1. The PCB board integrates the integrated circuits and electronic components necessary for the operation of this embodiment, including a WiFi module for communication with external devices and an image sensor for processing optical signals into electrical signals. The PCB board also includes a timing module, which allows setting the duration of a single operation of the pump system. It should be noted that the gun barrel section 2 of the housing 1 has multiple buttons for operating the timing module.

[0032] The liquid dispensing system includes a dispensing pipe 6, a storage bottle 5, and a spray head 7. The dispensing pipe 6 is connected to the storage bottle 5 via the aforementioned pump system. Under the action of the pump system, the liquid medicine in the storage bottle 5 enters the dispensing pipe 6 and is sprayed out from the spray head 7. Figures 1 to 2 As shown, the dispensing tube 6 is assembled at the front end of the gun barrel 2 of the housing 1, and adopts a malleable flexible tube with an internal metal wire, which can be bent into any shape as needed. The storage bottle 5 is used to store the liquid medicine, such as... Figure 1 or Figure 2 As shown, the liquid storage bottle 5 is detachably assembled to the gun barrel 2 of the housing 1 by means of threads. The spray head 7 is assembled at the front end of the liquid outlet tube 6 and can be any of the following structures: a) a common spray head with several micro-holes, each micro-hole having a diameter of less than 0.2 mm; b) a piezoelectric spray head, which is electrically connected to the above-mentioned control system and power system via wiring arranged in the side wall of the liquid outlet tube 6.

[0033] The visualization system provides doctors with a field of vision to accurately deliver the spray head 7 to the target location for anesthesia. The visualization system includes an imaging lens 8 positioned at the front end of the discharge tube 6, a cold light source housed inside the housing 1, and a first optical fiber and a second optical fiber 9 arranged in the sidewall of the discharge tube 6. The imaging lens 8 is connected to the image sensor via the first optical fiber, transmitting the light signal captured by the imaging lens 8 to the image sensor. The cold light source is a conventional medical LED cold light source, electrically connected to the power supply system via a control system. Furthermore, the cold light source is connected to the second optical fiber 9, guiding light to the front end of the discharge tube 6 to illuminate the area in front of the spray head 7.

[0034] It should be noted that the visualization system in this embodiment requires an external device (such as a mobile phone or tablet) with a corresponding app installed to be used, as detailed below:

[0035] First, a communication connection is established with the external device that has launched the corresponding app using the WiFi module on the PCB board. The light signal captured by the imaging lens 8 is transmitted to the image sensor on the PCB board via the first optical fiber. After the image sensor converts the light signal into an electrical signal, it is transmitted to the external device by the WiFi module, so that the image can be displayed in the app on the external device.

[0036] When performing laryngeal anesthesia on a patient using this embodiment, the duration of a single operation of the pump system is first set using the timing module on the PCB board, thereby setting the dosage for a single administration. Then, the doctor holds the grip 3 of the housing 1 to control the insertion of the dispensing tube 6 and the spray head 7 into the patient's throat. During operation, a visualization system can be used to display a real-time image in front of the spray head 7, and the insertion direction of the spray head 7 can be adaptively adjusted by referring to the image. Finally, when the spray head 7 is inserted into the designated position, the pump system is started, controlling the liquid in the reservoir 5 to enter the dispensing tube 6 and spray out from the spray head 7 until the pump system stops, at which point the spray head 7 and the dispensing tube 6 can be removed.

[0037] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above 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 utility model should be included within the protection scope of the present utility model.
