Description

TECHNICAL FIELD

[0001] The present invention relates to a drug aerosol supply device for a respirator, which allows a drug in an aerosol state to be contained in air processed in a respirator and to be delivered to a lung through a trachea when a patient inhales. BACKGROUND

[0002] Generally, a patient who has difficulty in breathing autonomously needs to rely on a respirator for breathing. In addition, a drug prescription can be given according to a doctor's judgment, and the drug can be contained in air processed by a respirator and provided to a patient thereby. Different drugs can be used according to a patient's physical state, for example, a drug that helps lung function can be used when lung function is poor.

[0003] Next, a general respirator will be described with reference to the accompanying drawings. Figure 1 The configuration of a general respirator will be described. Figure 1 FIG. 1 is a schematic diagram for describing the configuration of a general respirator.

[0004] A general respirator includes an air purification device 1, a first tube 2, a warming and humidifying device 3, a second tube 4, a Y tube 5, and a return tube 6.

[0005] The air purification device 1 can purify air, adjust an appropriate oxygen concentration, and set a pressure and a speed.

[0006] First air, which has been processed in the air purification device 1, is discharged and reaches the warming and humidifying device 3 along the first tube 2.

[0007] The warming and humidifying device 3 can increase the humidity of the first air and increase its temperature by heating. The temperature can be generally set to a temperature similar to a body temperature, for example, 36°C to 37°C.

[0008] Second air, which has been processed in the warming and humidifying device 3, reaches the Y tube 5 along the second tube 4.

[0009] An inlet through which the second air flows, an outlet connected to a mask or a mouthpiece, and an exhaust port for discharging air when exhaling are formed in the Y tube 5.

[0010] Air flow in the Y tube 5 can change according to inhalation and exhalation. For example, when a patient inhales, the second air can flow to the outlet through the inlet. The Y tube 5 forms air flow from the outlet to the exhaust port when the patient exhales.

[0011] The return tube 6, which is connected to the air purification device 1 that processes air when exhaling, is connected to the exhaust port of the Y tube 5.

[0012] In addition, a drug prescription can be given according to the state of the patient, and in order to administer the drug, a T-tube is generally inserted between the warming and humidifying device 3 and the second tube 4 and the drug is injected into the T-tube.

[0013] The T-tube can convert the drug into an aerosol state by a spraying method, which is a method in which the pressure is lowered as the air flow is accelerated and the drug is inhaled by means of the lower pressure, and then the drug is converted into a fine particle form by a spraying air flow.

[0014] However, the spraying method currently used can cause a change in the physical properties of the treated first air or the treated second air. In order to use the spraying method, high-pressure air needs to be additionally supplied from the outside, and problems such as a decrease in oxygen concentration, an increase in air pressure, or an increase in the flow speed of air can occur in the process as described above.

[0015] In particular, even if the oxygen concentration is set according to the lung function of the patient, the oxygen concentration in the air actually provided to the patient can be low, thereby causing a serious problem due to oxygen deficiency.

[0016] In addition, when the pressure or speed of the air provided to the patient is high, problems such as difficulty in breathing or inability to breathe naturally can occur.

[0017] Meanwhile, the current method of putting the drug into the T-tube and containing the drug in an aerosol state as the second air flows causes a problem in that the drug is continuously consumed regardless of the breathing state of the patient. In particular, when the patient exhales, the drug cannot reach the lung organ of the patient and is directly discharged, thereby causing a problem of waste of the drug.

[0050] The advantages and features of the present invention, and the methods for achieving them, will become even clearer through the following detailed description of the embodiments in conjunction with the accompanying drawings.

[0051] Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the embodiments described below are merely exemplary to aid in understanding the present invention, and the present invention can be implemented through various modifications different from those described herein. Furthermore, in the process of describing the present invention, when it is determined that a detailed description of a related well-known function or constituent element would obscure the essence of the invention, related detailed descriptions and specific illustrations will be omitted. Additionally, the accompanying drawings are not drawn to scale; rather, the size of some constituent elements may be exaggerated to aid in understanding the present invention.

[0052] Furthermore, terms such as "first" and "second" may be used in the description of various constituent elements, but the constituent elements are not limited by these terms. These terms are merely used to distinguish one constituent element from others. For example, without departing from the scope of the claims of this invention, a first constituent element may be named a second constituent element, and similarly, a second constituent element may be named a first constituent element.

[0053] Meanwhile, the terminology used thereafter is defined with reference to its function in this invention, and may vary depending on the manufacturer's intent or practice; therefore, it should be defined based on all the contents of this specification. Throughout this specification, the same reference numerals denote the same constituent elements.

[0054] Next, please refer to Figure 2 as well as Figure 3 A detailed description will be given of a drug aerosol supply device for an artificial respirator according to an embodiment of the present invention. Figure 2 This is a schematic diagram illustrating a drug aerosol supply device for an artificial respirator according to an embodiment of the present invention. Figure 3 This is a schematic diagram illustrating the main components of a drug aerosol supply device for an artificial respirator according to an embodiment of the present invention.

[0055] The drug aerosol supply device for an artificial respirator according to an embodiment of the present invention may include an inspiratory breathing detector 10, a T-tube 20, a cap 40, and a filling material sealing member 50.

[0056] Air purification device 1 is used to exhaust a first batch of air with a pre-set oxygen concentration, pressure, and velocity. The oxygen concentration can be set according to the patient's lung function capacity; for example, when lung function is at half the level of a normal person, the oxygen concentration can be set to approximately 40%.

[0057] The inhalation and breathing detector 10 can be connected to the air purification device 1, and can detect the first air and generate a detection signal when the first air is discharged from the inhalation and breathing detector 10.

[0058] The first tube 2 is connected to the inhalation and breathing detector 10, allowing the first air to move.

[0059] The heating and humidifying device 3 is connected to the first pipe 2, and can generate and discharge the second air by adjusting the temperature and humidity of the first air.

[0060] The second pipe 4 is connected to the heating and humidifying device 3, allowing the second air to move.

[0061] The T-pipe 20 has a branch pipe 24 formed on one side of the straight pipe 22, allowing the second air to pass through by connecting the straight pipe 22 to the second pipe 4.

[0062] The drug particle generating device 30 is mounted on the branch pipe 24 and sprays the drug in particle form into the second air by operating only when the detection signal is input.

[0063] One side of the Y tube 5 can be connected to the T tube 20, while the other side can be connected to a mask or mouthpiece.

[0064] One side of the return air pipe 6 is connected to the Y pipe 5 and the other side is connected to the air purification device 1, allowing airflow during exhalation.

[0065] The drug aerosol supply device for a ventilator according to an embodiment of the present invention, configured as described above, can have a drug particle generating device 30 disposed at the inlet of the Y-tube 5, and the drug particle generating device 30 can convert the drug into particles by ultrasonic vibration, thereby minimizing the distance from the point of drug generation in aerosol form to the mask or mouthpiece. That is, because the movement distance of the drug in particle form is very short, even converting a small amount of drug into particle form can achieve a good drug effect.

[0066] Furthermore, according to an embodiment of the present invention, the drug aerosol supply device for a ventilator does not require additional external air input, thereby maintaining the oxygen concentration, pressure, and velocity of the first and second air processed by the air purification device and the heating and humidification device, so that the patient can breathe more naturally.

[0067] Furthermore, the drug aerosol supply device for a respirator according to an embodiment of the present invention can drive the drug particle generating device to work based on the signal generated in the inspiratory breathing detector, thereby enabling accurate spraying at the time of drug consumption and significantly reducing drug waste.

[0068] In the drug aerosol supply device for a ventilator according to an embodiment of the present invention, the detection signal for driving the drug particle generation device 30 to operate can be, in addition to detecting the first air discharged from the air purifier 1, also in the manner described below.

[0069] 1) The detection signal may be a signal that detects the time of chest expansion of a patient by installing a chest sensor on the patient's chest. During breathing, the chest will repeatedly rise and fall, and therefore this movement can be detected and used as a detection signal.

[0070] 2) The detection signal can be a specific brainwave signal that occurs when the patient breathes. Specific brainwaves are generated in the brain when the lungs are functioning, and therefore can be used as a detection signal by detecting these brainwaves.

[0071] 3) The detection signal can be a signal that detects airflow during inhalation by being mounted on a mask or mouthpiece. Since the airflow directions during inhalation and exhalation differ, this difference can be detected and used as a detection signal.

[0072] 4) The detection signal can be a signal detected by installing a mask or a mouthpiece to detect the air pressure when inhaling. The pressure when inhaling is different from the pressure when exhaling, and thus the difference can be detected as a detection signal.

[0073] 5) The detection signal can be a signal detected by installing a mask or a mouthpiece to detect the air temperature when inhaling. The temperature when inhaling is different from the temperature when exhaling, and thus the difference can be detected as a detection signal.

[0074] That is, in the drug aerosol supply device for an artificial respirator according to the embodiment of the present application, the detection signal generated in the inhalation breath detector 10 can be replaced by one of the various examples described above, or the various examples described above can be applied at the same time and the drug particle generating device can be driven to operate when a certain detection signal is generated.

[0075] The drug particle generating device 30 can include a cannula 32, a particle generating element 34, a cartridge 36, a cap 40, and a filler stopper 50, as shown in FIG. 4. Figure 3

[0076] The cannula 32 can be assembled to the branch pipe 24.

[0077] The particle generating element 34 can be disposed outside the cannula 32 and convert a drug into a particle state. For example, the particle generating element 34 can convert a drug into a particle state using ultrasonic vibration, and thus detailed descriptions thereof will be omitted because the technology can be applied to a well-known technology.

[0078] The cartridge 36 is disposed at an upper portion of the particle generating element 34 and serves to store a drug.

[0079] The cap 40 is disposed to cover the cartridge 36, thereby preventing a drug stored in the cartridge 36 from being exposed to the outside.

[0080] The filler stopper 50 can be installed to the cap 40 and can be provided with a filler 52 having a flexibility. Specifically, the filler 52 can be formed of a flexible rubber, thereby allowing a needle to pass through the filler 52 when the needle is inserted and allowing a portion passed through by the needle to be immediately closed by the flexibility of the filler 52 itself when the needle is withdrawn. Thereby, the cartridge 36 can be always isolated from the outside.

[0081] That is, the drug aerosol supply device for an artificial respirator according to the embodiment of the present application can inject a drug into the cartridge 36 by inserting a needle into the filler 52. ​

[0082] According to the drug aerosol supply device for a respirator according to the embodiments of the present application, exposure of the inside of the cartridge 36 can be prevented from the beginning, and thus the cartridge can be prevented from being contaminated, and the patient can live in a more strictly clean environment.

[0083] Further, by preventing exposure of the inside of the cartridge 36, the entire section of the respirator circuit, particularly the entire pipe section from the air purifying device 1 to the mask or mouthpiece, can be strictly prevented from being exposed to the outside.

[0084] The embodiments of the present application described above are explained with reference to the accompanying drawings in the foregoing description, but it will be understood by those skilled in the art concerned that the present application can be embodied in other specific forms without changing the technical idea or essential characteristics thereof.

[0085] Therefore, the embodiments described in the foregoing description are merely exemplary and not limiting in all respects, the scope of the present application should be defined by the appended claims, and the meaning and scope of the claims and all modifications or variations derived from the equivalent concepts thereof should be interpreted as being included in the scope of the present application.
