Abstract

The present invention provides a method for converting a conventional disposable medical tube into a new medical tube with an additional endoscope function. The distal end of the medical tube is added to a small transparent housing for containing an internal light source, which may be any small size LED, OLED or μ LED device. In addition, the tube has one additional lumen for mounting a power cord for the illumination source and another isolated lumen for insertion of a flexible endoscope (video/image camera system) to view a target within the human body. To reduce the outer diameter and cost, the endoscope does not contain any built-in light source. In use, the endoscope is first inserted into the medical tube through its particular lumen and the light source at the tip is turned on. Secondly, the whole medical tube is safely inserted into a human body for diagnosis or treatment by means of endoscope video. Typically, the medical tube is disposable and the endoscope can be reused after a suitable sterilization procedure.

Detailed Description

The present invention is described in further detail below with reference to exemplary and illustrative drawings of the invention, but the description is not intended to limit embodiments of the invention, and any similar structures and similar modifications of the invention are intended to be included within the scope of the invention.

The invention relates to a medical tube with an additional endoscope function. The present invention includes, but is not limited to, catheters, gastric tubes, nasogastric tubes, esophageal tubes, rectal tubes, tracheal tubes, and the like having a medical tube insertable into a human body.

The first seven embodiments take a catheter with additional endoscopic functions as an example, and the features of the first seven embodiments can be applied to other medical tubes.

A urinary catheter with additional endoscopic functionality has a tubular housing with a distal end 121, a catheter shaft 120 and a proximal end 122.

Illumination sources

190 and 510 may be mounted in distal end 121 or balloon 110, depending on design requirements. The tubular housing has a plurality of lumens therein and a plurality of tapered ports may be fabricated at the proximal end 122.

Fig. 1 shows a first embodiment of the present invention. The catheter with the pre-installed video/image camera system 200 is tubular. The catheter shaft 120 is connected at one end to a distal end 121 and at the other end to a proximal end 122 joined by four

tapered ports

140, 150, 160, 170. The illumination source 190 is mounted within a transparent housing 192 of the catheter.

Fig. 2 shows details of a video/image camera system 200. In fig. 2A, a video/image camera system 200 has an image sensor and a lens 220 at a tip 210. The video/image camera system 200 is bendable, and the video/image camera system 200 has a connection wire to transmit an image signal and supply power to the image sensor 220. Fig. 2B is a top view of the video/image camera system 200 along a major axis of the video/image camera system 200. The image sensor and the lens 220 are square, and the nib 210 is a circumscribed circle of the image sensor and the lens 220 to maximize an area of the image sensor 220.

The image sensor and lens 220 may be powered by a wirelessly rechargeable battery or a wirelessly non-rechargeable battery. For a rechargeable battery pack, the battery may be charged by placing the wireless charger 1600 near the battery.

Fig. 3 shows the distal end 121 and its adjacent portions. The transparent casing 192 is made of a material having high light transmittance and has the illumination source 190 inside the casing. The four

lumens

610, 620, 630, 640 are fabricated within a tubular housing.

The transparent shell 192 has a waterproof design and has a hydrophobic coating applied to the outer surface to prevent blood or urine from remaining on the surface.

First lumen 610 connects drain hole 130 to first tapered port 150. The first lumen 610 is used as a passage for urine flow. The drain hole 130 is spaced from the distal end 121. The drain hole 130 is the entrance for urine within the patient's bladder.

The second lumen 620 connects the transparent housing 192 with the second tapered port 140 to provide space for placement of the video/image camera system 200. Tip 210 is placed against the forward end of catheter distal end 121. The image sensor and lens 220 may capture an image of the patient's bladder.

Third lumen 630 connects illumination source 190 with third tapered port 160. A cable is placed within the third lumen 630 and connected to the illumination source 190 for power transmission. The cable terminates at a third cone 160 and is connected to an external power source.

In the case where the illumination source 190 is wirelessly powered by an external power source, the third lumen 630 is not necessary. In the case of an illumination source 190 having a built-in battery, the battery may or may not be rechargeable. If the battery is rechargeable, it can be recharged by placing a wireless charger near the battery.

A fourth lumen 640 connects an opening 900 in the transparent housing 192 with the fourth cone-shaped orifice 170. The fourth tapered port 170 serves as a priming port for the inlet of saline solution for cleaning the outer surface of the transparent housing 192. Liquid medication may also flow from the fourth tapered port 170 into the patient's bladder.

The fourth lumen 640 and the fourth tapered port 170 are also used for injecting other fluids or gases such as CO₂Or air, or for inserting laser/optical/medical treatment accessories.

The illumination source 510 may be selected from LEDs, OLEDs, muleds, infrared devices, laser devices, and X-ray devices, depending on design requirements. Different light sources emit light of different wavelengths.

The illumination source 190 may be removed from the catheter for recycling.

Two embodiments of the third lumen 630 and illumination source 190 configuration are shown in fig. 4. In the first embodiment, the illumination source 190A is an annular light source surrounding the second lumen 620. In the second embodiment, the

illumination sources

190B, 190C, 190D, 190E are rectangular shaped illumination sources arranged in a configuration surrounding the second lumen 620.

Fig. 5 is a cross-sectional view of the catheter taken along the direction a-a referenced in fig. 1. Inside the tubular housing there are four

circular lumens

610, 620, 630, 640.

In use, the catheter is placed within the bladder of a patient. The illumination source 190 is turned on and emits light through the transparent housing 192. The image sensor and lens 220 on the tip 210 of the video/image camera system 200 capture an image of the patient's bladder. After use, both the video/image camera system 200 and the illumination source 190 may be removed from the catheter.

The video/image camera system 200 and the illumination source 190 may be reused after an appropriate sterilization procedure.

Fig. 6 shows a second embodiment of the invention. In this embodiment, the present invention comprises two parts, including a catheter and a video/image camera system 200. The tubular catheter shaft 120 is connected at one end to a distal end 121 and at the other end to a proximal end 122 to which four

tapered ports

140, 150, 160, 170 are connected. The illumination source 190 is mounted within a transparent housing 192 of the catheter. The catheter has a lumen for insertion of the video/image camera system 200.

A third embodiment of the invention is shown in fig. 7. The catheter with the pre-installed video/image camera system 200 is generally tubular. The catheter shaft 120 is connected at one end to a distal end 121 and at the other end to a proximal end 122 having five tapered

ports

140, 150, 160, 170, 175 connected together. In use, the distal end 121 of the catheter is inserted into the bladder of a patient, and saline solution or air is passed to inflate the balloon 110 to prevent the catheter from slipping out of the bladder neck of the patient. The image sensor and lens 220 of video/image camera system 200 may be inserted into balloon 110. Illumination source 510 may also be inserted into balloon 110 to provide sufficient illumination.

Fig. 8 shows a portion of a catheter with an inflated balloon 110. Balloon 110 is made of a transparent material capable of conducting light. Balloon 110 has two layers, an outer layer 110A and an inner layer 110B. The video/image camera system 200 may enter the interlayer between the outer layer 110A and the inner layer 110B. Saline solution or air is injected into the space surrounded by inner layer 110B to inflate balloon 110. The middle layer of balloon 110 is part of second lumen 820 and allows video/image camera system 200 to pass through. In fig. 7, illumination source 510 and tip 210 of video/image camera system 200 are placed at balloon 110.

Fig. 9 is a cross-sectional view of the catheter taken along the direction B-B referenced in fig. 7. Five lumens are within the tubular housing. The lumen may be designed in different shapes depending on the design requirements.

The first lumen 810 connects the exhaust hole 130 with the first tapered port 150, which serves as a passage for urination. Second lumen 82 connects transparent shell 192 with the middle layer of balloon 110To the second tapered port 140 to allow the video/image camera system 200 to pass through the middle layer. Third lumen 830 connects distal end 121 with third tapered port 160. A thin wire bundle of appropriate length and diameter is assembled inside the third lumen 830 to power the illumination source 510. A fourth lumen 840 connects the fluid opening 910 with the fourth tapered port 175. The fourth tapered port 175 is an inlet for the washing fluid. The fluid may clean blood or urine remaining on the outer surface of balloon 110. The fourth lumen 840 and the fourth tapered port 175 are also used for injecting other fluids or fluids such as CO₂And air, or for insertion of laser/optical/medical treatment accessories. Fifth tapered port 170 serves as a bi-directional port for air or saline solution to inflate or deflate balloon 110. Fifth lumen 850 connects the interior space of balloon 110 to fifth tapered port 170.

The video/image camera system 200 enters the catheter through a separate and isolated lumen from the urine drain. Thus, the video/image camera system 200 is not contaminated by urine or blood.

Illumination source 510 is first placed at distal end 121 along with tip 210 of video/image camera system 200. The illumination source 510 is located behind the tip 210 relative to the front surface of the transparent housing 192.

The video/image camera system 200 may be pulled along the second lumen 820 to a position within the balloon 110. Illumination source 510 may be moved to a position around or within balloon 110 accordingly to provide sufficient illumination for video/image camera system 200.

In the case where the illumination source 510 is wirelessly powered by an external power source, the third lumen 830 is not necessary. In the case of a lighting source 510 having a built-in battery, the battery may or may not be rechargeable. If the battery is rechargeable, it can be recharged by placing a wireless charger near the battery.

The illumination source 510 is selected from an LED, OLED, μ LED, infrared device, laser device, and X-ray device, according to design requirements. Different light sources emit light of different wavelengths for various applications.

The two layers of balloon 110 are made of a transparent material having elastic deformability. Balloon 110 is sufficiently spaced from the drainage hole. Saline solution or air is injected into the fourth tapered port 170 and the fifth lumen 850, and then the balloon 110 is inflated. The inflated balloon 110 prevents the catheter from slipping out of the patient's bladder. Saline solution or air may be vented through the same path to deflate balloon 110.

In use, a catheter is inserted into the bladder of a patient. Balloon 110 is inflated and illumination source 510 is turned on. If desired, illumination source 510 is pulled into position in transparent balloon 110 for illumination. The image sensor and lens 220 of video/image camera system 200 may be pulled into the interlayer of balloon 110 to capture an image. If blood or urine remains on the outer surface of balloon 110 and further obscures the image taken by camera system 200, fluid may be injected and ejected from fluid opening 910 via fifth tapered port 175 to clean the surface. After use, the video/image camera system 200 may be removed from the catheter.

A fourth embodiment of the invention is shown in fig. 10. The catheter with the pre-installed video/image camera system 200 is generally tubular. The catheter shaft 120 is connected at one end to a distal end 121 and at the other end to a proximal end 122 having five tapered

ports

140, 150, 160, 170, 175 connected together. In use, the distal end 121 of the catheter is inserted into the bladder of a patient, and the balloon 110 is inflated with saline solution or air to prevent the catheter from slipping out of the bladder neck of the patient. The video/image camera system 200 is placed in the second lumen 820. The tip 210, which contains an image sensor and lens, is capable of transmitting images within the bladder of a patient. Two

illumination sources

190 and 510 provide sufficient illumination for the image sensor.

Fig. 11 shows a portion of a catheter with an inflated balloon 110. The balloon is made of a transparent material having high light transmittance. Balloon 110 has two layers, an outer layer 110A and an inner layer 110B. The video/image camera system 200 is capable of entering the interlayer sandwiched between the outer layer 110A and the inner layer 110B. Saline solution or air is injected into the space surrounded by inner layer 110B to inflate balloon 110.

The first lumen 810 connects the exhaust hole 130 with the first tapered mouth 150 as a urination passage. The second lumen 820 is to cover the transparent shellIntermediate layers of the body 192 and the balloon 110 are connected to the second tapered port 140 and allow the video/image camera system 200 to pass through. Third lumen 830 connects distal end 121 with third tapered port 160. A thin wire bundle of suitable length and diameter is assembled within the third lumen 830 for transmitting power to the illumination source 510. A fourth lumen 840 connects the fluid opening 910 with a fourth tapered port 170, which is the inlet for the washing fluid. Fluid is sprayed onto the observed outer surface to clean the blood or urine as desired. The fourth lumen 840 and the fourth tapered port 170 are also used for injecting other fluids or gases such as CO₂Or inserted into a laser/optical/medical treatment accessory. Fifth tapered port 175 is a bi-directional port that conducts air or saline solution to inflate or deflate balloon 110. Fifth lumen 850 connects the interior space of balloon 110 to fifth tapered port 175.

Illumination source 190 is mounted at distal end 121 of the catheter and illumination source 510 is mounted at a portion of balloon 110. The two light sources are connected to wires within the third lumen 830. The on/off state of each light source may be controlled at the third tapered port 160.

The illumination source 190 is selected from an LED, OLED, μ LED, infrared device, laser device, and X-ray device according to design requirements. Different light sources emit light of different wavelengths for various applications.

In the case where the illumination source 190 is wirelessly powered by an external power source, the third lumen 830 is not necessary. In the case of an illumination source 190 having a built-in battery, the battery may or may not be rechargeable. If the battery is rechargeable, it can be recharged by placing a wireless charger near the battery.
