Description

Technical Field

[0001] The present invention relates to a disposable endoscope, in particular to a disposable endoscope which can prevent cross infection during intubation and has a light source to facilitate image capture, and can be used for spraying medicine, suctioning sputum, and giving oxygen during the intubation process to relieve the patient's discomfort during the intubation process. Background Art

[0002] At present; general medical endoscope 10, such as Fig.14 As shown, a soft and flexible bougie 101 is provided, a tube body 102 is provided at the front end of the bougie 101, a filter, a lens 103 and a light emitting element are provided inside the tube body 102, and a connector 104 for connecting a control circuit is provided at the rear end. When in use, the endoscope 10 is inserted into the patient's mouth, and the control circuit is connected to a host with a display screen. The image of the organ is captured by the lens after being illuminated by the light emitting element, and then the image signal is transmitted to the control circuit provided at the rear end of the endoscope 10, so that the image can be viewed on the display screen of the host.

[0003] After using the existing endoscope 10, some countries will discard the entire bougie 101. Although this can completely prevent cross infection, the cost of the bougie 101 is not low, and it is not affordable for every country. Therefore, most countries use appropriate disinfection operations to prevent cross infection, which is not only time-consuming, but also unable to completely prevent cross infection. Although there is a sheath 105 that can be placed on the bougie 101 at this stage, the sheath 105 only needs to be discarded after use, which can greatly reduce the cost of using the endoscope 10. However, since the light-emitting element is disposed on the tube 102 at the front end of the bougie 101, the sheath will somewhat affect the quality of the image captured by the lens.

[0004] In addition, endoscopy is to directly observe whether there are lesions in the digestive tract through various endoscopes, and to slice and perform pathological histological examinations when necessary, or to track the progression of lesions, or to evaluate the therapeutic efficacy of lesions. However, another positive function of current endoscopy is therapeutic endoscopy, which is inserted from the patient's mouth through a tracheal tube to achieve the aforementioned medical process. However, since some patients are not suitable for general anesthesia during surgery, they need to be intubated in an awake state after being evaluated by a physician. However, since patients are in an awake or semi-awake state, endoscopy can easily cause reflex actions such as coughing and convulsions, which not only affects medical operations but may also endanger the patient's life. Therefore, it is necessary to perform intubation after topical anesthesia during the intubation process, and even medical actions such as suctioning sputum and giving oxygen during the medical process to make the implementation of endoscopy smoother.

[0005] Although there are endoscopes available today that can be used for spraying medicine (anesthesia), suctioning sputum, and oxygen administration, they are quite expensive and therefore cannot be discarded after use. Instead, they must be disinfected before use by the next patient. However, since the components of spraying medicine (anesthesia), suctioning sputum, and oxygen administration are integrated with the endoscope, many blind spots are formed, making the disinfection operation quite troublesome and time-consuming, which relatively increases the cost of medical treatment. Moreover, if the subsequent disinfection is not accurate or complete, it is more likely to cause cross-infection of pathogens. In view of this, the applicant, through continuous research and experiments, has come up with the idea of ​​designing a disposable endoscope that can prevent cross-infection during the intubation medical process, has a light source to facilitate image capture, can be used for spraying medicine, suctioning sputum, and oxygen administration to relieve the discomfort of patients during the intubation process, and can be discarded after use to prevent cross-infection.

The tube body 12 at the front end of the bougie 11 is provided with a conductive terminal 15 protruding from the vertical wall surface of the tube body 12 and connected to the rear end connector 14.

[0017] The outer cover 2 includes a fixing seat 21 and a sleeve portion 22 connected to the fixing seat 21. A lens 3 and a circuit unit 4 are provided at the front edge of the fixing seat 21. The surface of the lens 3 is provided with an annular groove 31, the periphery is provided with a step portion 32, and a notch 33 is provided at an appropriate position of the periphery. The outer cover 2 is juxtaposed with one or more channel tubes 23. In this embodiment, the front end of the channel tube 23 protrudes from the front end of the outer cover 2 by an appropriate length, and the end of the channel tube 23 can be connected to the injection port tube 24 or other components; the sleeve portion 22 is made of plastic; the channel tube 23 and the outer cover 2 are connected or covered with each other, so that the channel tube 23 and the outer cover 2 are juxtaposed.

[0018] The circuit unit 4 includes a first circuit board 41 and a second circuit board 42. The first circuit board 41 and the second circuit board 42 are connected by a connecting section 43, so that the connecting section 43 can be bent vertically and horizontally continuously, so that the second circuit board 42 is arranged horizontally above the first circuit board 41. The first circuit board 41 is provided with two conductive parts 411 of appropriate length, and the upper edge is connected to the second circuit board 42 by a connecting section 43; the second circuit board 42 is in a ring sheet shape, and a plurality of light-emitting elements 44 are provided on the second circuit board 42, so that these light-emitting elements 44 are electrically connected to the conductive part 411. In this embodiment, the connecting section 43 is equal to or slightly smaller than the notch 33 of the lens 3; the second circuit board 42 is equal to or slightly smaller than the groove 31 of the lens 3; the first circuit board 41 and the second circuit board 42 of the circuit unit 4 are flexible printed circuits (FPC) to facilitate bending; these light-emitting elements 44 can be set as light-emitting diodes (LEDs) of the same color or different colors according to different medical or inspection requirements.

[0019] The second circuit board 42 of the circuit unit 4 can be bent 90 degrees to a horizontal shape, so as to be embedded in the groove 31 of the lens 3, so that the connecting section 43 is placed in the notch 33 of the lens 3; the first circuit board 41 can be rolled up so that the two conductive parts 411 are wrapped around the inner edge of the first circuit board 41. The assembled lens 3 and circuit unit 4 are sleeved and fixed on the fixing seat 21 of the outer cover 2, so that the inner edge of the end of the fixing seat 21 is embedded in the step portion 32 of the lens 3, so that the lens 3 and the light-emitting element 44 are exposed from the front end of the fixing seat 21.

[0020] The sleeve 5 is generally conical in shape and has a through hole 51 . A groove 52 extending from the front end to the rear end is formed on the surface of the sleeve 5 . The groove 52 passes through the surface of the sleeve 5 to the through hole 51 .

[0021] The combination of the above components forms a disposable endoscope. When intubation is performed, the endoscope 1 is inserted into the outer cover 2 through the sleeve portion 22, and then inserted into the sleeve member 5 through the through hole 51, and the channel tube 23 is clamped in the cut groove 52. The channel tube 23 will not be displaced due to bending or pulling through the clamping and positioning of the cut groove 52. The endoscope 1 covered with the outer cover 2 is then inserted into the endotracheal tube 6, and the sleeve member 5 is embedded in the entrance 61 of the endotracheal tube 6 to form a positioning for insertion into the patient's trachea, and then the plug-in member 14 is plugged into a control circuit 7. When the endoscope 1 is inserted into the outer cover 2, the conductive terminal 15 provided on the tube body 12 of the bougie 11 will contact the conductive portion 411 of the first circuit board 41 of the circuit unit 4, so that the light-emitting element 44 and the control circuit 7 form electrical conduction, so that the light-emitting element 44 is lit by the control circuit 7, so that the endoscope 1 can capture images. During the intubation medical treatment process, the channel formed by the channel tubes 23 placed in parallel with the outer cover 2 can be used for spraying medicine, suctioning sputum, and giving oxygen to relieve the patient's discomfort during the intubation process. After use, the endoscope 1, the outer cover 2, the sheath 5, the endotracheal tube 6, and the control circuit 7 can be completely or partially discarded. In addition to reducing the tedious work of subsequent disinfection, the purpose of preventing cross infection can be achieved.

[0022] Please also see Figure 8 and Fig. 9 , which is a stereoscopic view of the present invention after assembly and a cross-sectional view of the endoscope sleeved in the outer cover. As shown in the figure, when the present invention is used for intubation medical treatment, the endoscope 1 is sleeved in the outer cover 2 for insertion into the patient's endotracheal tube 6. After being illuminated by the light-emitting element 44 at the front end of the outer cover 2, the image of the organ is captured by the lens 13, and the image signal is then transmitted to the control circuit 7 at the rear end of the endoscope 1. The control circuit 7 transmits the image signal to a host computer so that the image can be viewed on the display screen of the host computer. After the intubation medical treatment is completed, the endoscope 1, the outer cover 2, the sleeve 5, the endotracheal tube 6 and the control circuit 7 can be completely or partially discarded to prevent cross infection. When the endoscope 1 of the present invention is inserted into the outer cover 2, the conductive terminal 15 provided on the wall surface of the tube body 12 of the endoscope 1 will contact the conductive portion 411 of the first circuit board 41 of the circuit unit 4, and the power signal of the control circuit 14 is transmitted to the conductive portion 411 through the conductive terminal 15, and then transmitted to the light-emitting elements 44 of the second circuit board 42 by the conductive portion 411, so as to light up the light-emitting elements 44. Among them, since the two conductive portions 411 are wrapped around the inner edge of the first circuit board 41, when the endoscope 1 is inserted into the outer cover 2, the conductive terminal 15 can be made to contact the conductive portion 411 of the first circuit board 41 without any angle positioning, which is very convenient and fast to use.

[0023] Please also see Fig.10 and Fig.11, is a diagram of the use state of the present invention. When the present invention is used, in addition to the combination of the endoscope 1, the outer cover 2, and the endotracheal tube 6 for intubation medical treatment, medical operations such as spraying medicine, suctioning sputum, or oxygen administration can be performed simultaneously during the aforementioned intubation medical treatment process. As in this embodiment, medical personnel can insert the syringe 8 containing the medicine into the injection port tube 24 at the end of the channel tube 23, inject the medicine from the injection port tube 24, and then release the medicine from the front end of the channel tube 23 through the channel tube 23, so that the intubation medical treatment is smoother. The present invention can also insert the syringe 8 into the injection port tube 24 at the end of the tube body 14, and extract the sputum through the syringe 8. In addition, an oxygen supply device can also be connected through the channel tube 23 to deliver the required oxygen. The purpose of oxygen supply is that when intubation is in progress, the lens 13 of the endoscope 1 may be contaminated with sputum, blood or other mucus. By supplying oxygen, the sputum, blood or other mucus in front of the lens 13 can be cleared to prevent the sputum, blood or other mucus from blocking the lens 13, thereby keeping the lens 13 clean, which is beneficial for the endoscope 1 to capture images.

[0024] See also Fig.12 , is a three-dimensional diagram of another embodiment of the present invention. Figure 2 As shown in the figure, the present invention can be provided with two or more channel tubes 23 on the aforementioned outer cover 2. Similarly, the front ends of these channel tubes 23 protrude from the front end of the outer cover 2 by an appropriate length, and the ends can be connected to the injection port tube 24 or other components. Moreover, these channel tubes 23 can pass through the cutout groove 52 of the sleeve 5, so that the channel tubes 23 are clamped in the cutout groove 52, and the sleeve 5 is inserted into the inlet 61 of the endotracheal tube 6 to form a positioning, so that a plurality of channel tubes 23 can pass through for simultaneous medical operations such as spraying, suctioning or oxygen administration.

[0025] See also Fig.13 , which is a three-dimensional diagram of another embodiment of the present invention. As shown in the figure, the present invention can set a medicine spraying structure 9 at the front end of the channel tube 23 placed in parallel with the outer cover 2. During the intubation medical treatment, the medicine is injected through the injection port tube 24 at the end of the channel tube 23, so that the medicine passes through the channel tube 23 and is sprayed outward through the medicine spraying structure 9 to achieve the purpose of spraying medicine. This makes the drug administration during the intubation medical operation more convenient and makes the patient more comfortable during the medical treatment process.

[0026] The above embodiments are only for illustrating the preferred implementation of the present invention, but not for limiting the scope of the present invention. Any slight modification or change will not lose the essence of the present invention and will not deviate from the spirit of the present invention.

[0027] In summary, the present invention uses an outer cover with a light-emitting element, an endoscope with a conductive terminal, and a channel tube placed in the outer cover to form a disposable endoscope. During intubation, the outer cover can be put on the endoscope to prevent cross infection, and a light source is provided at the end of the outer cover to facilitate image capture, and during the intubation process, it can be used for spraying medicine, suctioning sputum, and giving oxygen to relieve the patient's discomfort during the intubation process, and can be discarded after use to prevent cross infection.
