Device to Kill Micro-Organisms Inside the Respiratory Tract

Abstract

A present idea relates to a device to kill micro-organisms inside the patient's respiratory tract using UV light, specifically UV-C. It is particularly used to treat patients with Coronaviruses family such as Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). The device consists of a triple-lumen catheter and UV control unit. The distal end of one of the catheter's lumen has a curved UV chamber while the proximal end has a cable with a socket to be connected to the UV control unit. The second lumen of the catheter is used for oxygen supply, and the third lumen of the catheter is used for suction.

Claims

1. A device with a catheter of three lumens, comprising; a first lumen, having a curved chamber with a UV LED; a second lumen, used for an oxygen supply; and a third lumen used for suction.

2. The device of claim 1, wherein the UV LED is powered and controlled by a UV control unit.

The drawings are briefly described as follows:

[0025] FIG. 1 is a perspective view of inserted device inside the respiratory tract of a patient.

[0026] FIG. 2 is a perspective view of a catheter with a curved UV chamber and UV control unit.

[0027] FIG. 3 is a perspective view of a curved UV chamber's components.

DETAILED DESCRIPTION

[0028] Reference will now be made to figures wherein like structure will be provided with like reference designations. It is understood that the drawings are diagrammatic and schematic representations of example implementations, and are not limiting of implementations nor are they are necessarily drawn to scale.

[0029] FIG. 1 depicts the feature of implementation of the present idea used for sterilization of contaminated air inside the respiratory tract. It is directly related to a triple lumen catheter 110. A catheter 110 may consist of a suction tube 118 to be used for suction 121. A distal end of a second catheter lumen 112 has a curved UV chamber 114 with UV LED 310 FIG. 3 to sterilize the air inside the trachea 126 of the patient respiratory tract 100.

[0030] The proximal end of the catheter lumen 112 has a cable with socket 122 to be connected to a UV control unit 210 FIG. 2. The third lumen of a catheter 113 is used for oxygen supplies 123.

[0031] UV LED 310 FIG. 3 inside a UV chamber 114 starts to emit UV energy after a power cable with socket 122 is connected to a UV control unit 210 FIG. 2. Oxygen supply 123 inside the oxygen supply lumen 113 exits from an opening 125 inside the trachea 126 and pushes the contaminated air inside the trachea 126 to enter UV chamber 114 via openings 126.

[0032] Contaminated air is now exposed to UV energy for sterilization inside the UV chamber 114. Oxygen valve on the surface of UV control unit 210 FIG. 2 (not shown for simplicity) is used to control the oxygen supply rate 113 to give the contaminated air enough time to be sterilized inside the UV chamber 114. When contaminated air is sterilized, an oxygen valve will be opened to allow for oxygen supply to push the sterilized air out of UV chamber 114 via openings 128.

[0033] At the same time, the suction valve (not shown for simplicity) will be opened to allow for the suction force 121 to suck the air out of the patient respiratory tract 100 via the opening 120.

[0034] The above procedure will be repeated until the contaminated air inside the trachea 126 is completely sterilized.

[0035] FIG. 2 shows a catheter with UV chamber and a UV control unit 200, wherein 210 is a UV control unit. Buttons 211 are used to increase or decrease UV output power.

[0036] 212 is a power cable of a device 210. 213 is an ON/OFF switch for a device 210. 214 is an alarm LED to give flashing light and sound in case of any problem, specifically in case UV power is outside certain limits. 215 is a small screen to monitor the actual UV output power in a real time.

[0037] 216 is a control knob for continuous or pulsed UV output.

[0038] FIG. 2 also shows the catheter's lumens 110, wherein 112 is one catheter lumen with a cable and socket 122 at its proximal end to be connected to UV control unit 210.

[0039] The distal end of a catheter lumen 112 is connected to a curved UV chamber 114. A catheter 110 has a second lumen 113 to be used for oxygen supply 123. 125 is the oxygen output opening. Catheter 110's third lumen 111 is used for suction 121 whereas 120 is an air suction inlet.

[0040] FIG. 2 also shows a curved UV chamber 114 with its inlet openings 126 and outlet openings 128.

[0041] FIG. 3 300 shows the components of a curved UV chamber 114, wherein 310 is UV LED. 311 is a base for UV LED 310 to fix UV LED 310 to UV chamber 114. 312 is the bottom part of a curved UV chamber 114 and 313 is its tip.
