Description

Technical Field

[0001] The utility model belongs to the field of medical devices, and particularly relates to a visual tracheal intubation assistance device capable of forming intermittent jet airflow. Background Art

[0002] The visual tracheal intubation assistance device is a medical device used for respiration, anesthesia and first aid. It has a visualization function and can improve the accuracy and safety of intubation. It consists of a hollow tube body, a camera, a display screen, operation buttons, etc. According to different usage scenarios and functions, it can be divided into various types.

[0003] When the existing visual tracheal intubation assistance device is in use, the camera at the front end of the tube body is often adhered to by the patient's saliva, sputum, etc., resulting in a significant reduction in clarity. In severe cases, the auxiliary function of visual intubation cannot be realized at all. After general anesthesia induction or for comatose patients, the pharyngeal muscles are relaxed, greatly reducing the operation space for tracheal intubation. In addition, the existing visual tracheal intubation assistance device usually does not have a ventilation function itself and cannot supply oxygen to the patient while assisting visual intubation. This requires that the intubation operation must be fast to avoid the patient having an oxygen deficiency problem. However, for inexperienced medical staff or patients with difficult airways, it is difficult to grasp the intubation time. Therefore, it is necessary to improve the structure of the existing visual tracheal intubation assistance device. Summary of the Utility Model

[0004] The utility model provides a visual tracheal intubation assistance device capable of forming intermittent jet airflow, aiming to overcome the above problems existing in the prior art to at least a certain extent.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: A visual tracheal intubation assistance device capable of forming intermittent jet airflow, including a hollow tube, a camera and an operation handle. The camera is arranged inside the front end of the hollow tube, and there is a ventilation gap for jetting airflow to the front end of the hollow tube between the outer side wall of the camera and the inner side wall of the hollow tube. The operation handle is fixedly connected to the rear end of the hollow tube. An air inlet interface communicating with the rear end opening of the hollow tube is arranged on the operation handle. The camera is electrically connected to one end of a signal line at the tail end of the operation handle through a cable built in the hollow tube, and the other end of the signal line is electrically connected to a display. The air inlet interface is communicated with the output end of an air inlet control component for controlling the intermittent ventilation frequency and ventilation air pressure through an air inlet hose one. The input end of the air inlet control component is communicated with an oxygen supply device through an air inlet hose two.

[0006] On the basis of the above technical solution, the utility model can also be improved as follows.

[0007] Further, the intake control assembly includes a pressure regulating valve, a solenoid valve, and a pressure gauge. The second intake hose is sequentially connected to the pressure regulating valve, the solenoid valve, and the pressure gauge, and then connected to the first intake hose.

[0008] Further, it further includes a control box. The pressure regulating valve and the solenoid valve are both installed inside the control box. The pressure regulating knob of the pressure regulating valve extends outside the control box. A power supply and an intermittent relay are also installed inside the control box. The solenoid valve is electrically connected to the power supply through the intermittent relay.

[0009] Further, the pressure gauge is fixed on the control box, and the air pressure acquisition end extends into the control box and is connected to the pipeline at the output end of the solenoid valve.

[0010] Further, a gas input interface communicating with the input end of the pressure regulating valve is provided on one side of the control box, and a gas output interface communicating with the output end of the solenoid valve is provided on the other side. The gas input interface is used to communicate with the second intake hose, and the gas output interface is used to communicate with the first intake hose.

[0011] Further, a diversion protrusion is provided on the inner wall of the front end of the hollow tube. The diversion protrusion bends towards the front end of the camera so that the airflow jetting forward through the ventilation gap first turns back to blow the front end lens of the camera and then jets forward.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The camera is located at the front end of the hollow tube and there is a ventilation gap for forming a forward jet airflow between the camera and the front inner wall. An intake interface communicating with the rear end of the hollow tube is provided on the operating handle. The intake interface is also connected to the intake control assembly through the second intake hose. The intake control assembly controls the intermittent ventilation frequency and ventilation air pressure. Therefore, during visual assisted intubation, the jet airflow at the front end of the hollow tube can blow away the sputum and saliva at the front end of the hollow tube, reducing the probability of the lens of the camera being adhered by sputum, saliva, etc. Moreover, even if adhered, it can be blown away by the jet airflow, thus ensuring that the camera always clearly shows the situation in front of it and ensuring a better assisted intubation effect. In addition, the intermittent jet of oxygen can also push open the soft tissues in the patient's oropharynx, providing a more open operating field of view. The jet airflow impacts the vocal cords, forming a special vibration sound, which is more conducive to determining the positional relationship between the tip of the tracheal catheter and the glottis. At the same time, the intermittent jet of oxygen can also supply oxygen to the patient during the assisted intubation process, thus ensuring that there is more operating time during intubation, enabling medical staff to complete the tracheal intubation operation more calmly.

[0019] The principles and features of the present utility model will be described below in conjunction with the attached drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0020] In the description of the present utility model, if terms indicating directions such as "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", etc. are used, the directions or positional relationships indicated are based on the directions or positional relationships shown in the attached drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be construed as a limitation to the present utility model.

[0021] As Figures 1 to 3 shown, the present utility model provides a visual tracheal intubation auxiliary device capable of forming intermittent jet airflow, including a hollow tube 1, a camera 2 and an operating handle 3. The camera 2 is disposed inside the front end of the hollow tube 1, and there is a ventilation gap for jetting airflow to the front end of the hollow tube 1 between the outer sidewall of the camera 2 and the inner sidewall of the hollow tube 1. The operating handle 3 is fixedly connected to the rear end of the hollow tube 1. An air intake interface 4 communicating with the rear end opening of the hollow tube 1 is provided on the operating handle 3. The camera 2 is electrically connected to one end of a signal wire 5 at the tail end of the operating handle 3 through a cable disposed inside the hollow tube 1. The other end of the signal wire 5 is electrically connected to a display. The air intake interface 4 is communicated with the output end of an air intake control assembly 7 for controlling the intermittent ventilation frequency and ventilation pressure through a first air intake hose 6. The input end of the air intake control assembly 7 is communicated with an oxygen supply device through a second air intake hose 8.

[0022] It should be noted that the pressure of the jet airflow is based on the standard of being able to disperse sputum without causing harm to human soft tissues. Besides the functions of supplying oxygen to the human body and dispersing sputum and saliva, the jet airflow can also blow open the closed soft tissues during intubation, making the intubation smoother. The intermittent ventilation frequency and ventilation pressure can be flexibly adjusted by medical staff according to specific situations.

[0023] In an embodiment of the present utility model, as Figure 3 shown, the intake control assembly 7 includes a pressure regulating valve 9, a solenoid valve 10, and a pressure gauge 11. The second intake hose 8 is sequentially connected to the pressure regulating valve 9, the solenoid valve 10, and the pressure gauge 11 and then connected to the first intake hose 6.

[0024] It can be understood that the pressure regulating valve can be manually adjusted or an electronic pressure regulating valve that can set a pressure range and automatically control the air pressure within that range.

[0025] Based on the above embodiment, it further includes a control box 12. The pressure regulating valve 9 and the solenoid valve 10 are both installed inside the control box 12. The pressure regulating knob 13 of the pressure regulating valve 9 extends outside the control box 12. A power supply 14 and an intermittent relay 15 are also installed inside the control box 12. The solenoid valve 10 is electrically connected to the power supply 14 through the intermittent relay 15.

[0026] It should be noted that the control box encapsulates the relevant components in a box body. During use, only the corresponding intake hoses need to be connected, which is more convenient to operate and the overall is more concise.

[0027] Based on the above embodiment, the pressure gauge 11 is fixed on the control box 12 and the air pressure acquisition end extends into the control box 12 and is connected to the pipeline at the output end of the solenoid valve 10.

[0028] It should be noted that the pressure gauge can be a mechanical pressure gauge or an electronic pressure gauge, which measures the air pressure in the second intake hose connected to the hollow tube.

[0029] Based on the above embodiment, a gas input interface 16 connected to the input end of the pressure regulating valve 9 is provided on one side of the control box 12, and a gas output interface 17 connected to the output end of the solenoid valve 10 is provided on the other side. The gas input interface 16 is used to connect to the second intake hose 8, and the gas output interface 17 is used to connect to the first intake hose 6.

[0030] It should be noted that the gas input interface and the output interface can preferably adopt Luer connectors that are convenient for both connection and disassembly.

[0031] On the basis of the above embodiments, a flow guiding protrusion 18 is provided on the inner wall of the front end of the hollow tube 1, and the flow guiding protrusion 18 is bent towards the front end of the camera 2 so that the airflow jetted forward through the ventilation gap is first turned back to purge the front end lens of the camera 2 and then jetted forward.

[0032] It should be noted that the flow guiding protrusion is equivalent to an inward flanging and protrudes appropriately towards the camera at the innermost edge after being folded, so that the jetted airflow is guided towards the camera lens and then jetted forward together.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
