The insertion portion of the disposable endoscope, the disposable endoscope and the method for using the same according to the embodiments of the present application will be described in detail with reference to fig. 1 to 13.
A first aspect of the present embodiment provides an insertion portion of a disposable endoscope.
The insertion portion of the disposable endoscope of this embodiment includes an insertion portion body 11 and a first marker portion 12, the first marker portion 12 is made of a water-soluble material, and the first marker portion 12 has at least a first form and a second form, when the first marker portion 12 is in the first form, the first marker portion 12 covers the outer surface of the insertion portion body 11, when the first marker portion 12 is in the second form, the first marker portion 12 is dissolved, when the first marker portion 12 is in contact with water, the first marker portion 12 is changed from the first form to the second form, as shown in fig. 1 to 4. Fig. 1 to 3 show a schematic view of the first marker 12 covering the outer surface of the insertion portion body 11, and fig. 4 shows a schematic view of the first marker 12 on the insertion portion body 11 after dissolution. The structure of the insertion portion body 11 can be the same as that of the prior art, and will not be described here again.
Preferably, for ease of viewing, the color of the first identification portion 12 may be visually distinguishable from the color of the outer surface of the insertion portion body 11. For example, the outer surface of the insert body 11 may have a skin that is generally black, and the first indicator 12 may be provided with a white color so that the first indicator 12 is clearly distinguishable from the insert body 11. Preferably, the water-soluble material can be water-soluble material in the prior art, such as high polymer materials such as polyethylene glycol (PEG), povidone (PVP) and the like.
Preferably, the first marking portion 12 is a special-shaped structure or an asymmetric structure with a complex shape, so as to avoid the problem of erroneous judgment caused by re-using the water-soluble material to shield the insertion portion body 11 under the condition that the first marking portion 12 is dissolved. Fig. 3 shows a schematic view of the first identification portion 12 provided with irregular serrations 122 at its edges.
The first marking part 12 in this embodiment is dissolved, that is, after the first marking part 12 encounters water, the first marking part 12 is dissolved in water, and the first marking part 12 disappears from the insertion part body 11. Further, the first marker 12 may be completely dissolved or partially dissolved in the first marker 12. Further, when the first identification portion 12 is partially dissolved, the dissolution proportion of the first identification portion 12 may be preset, and when the dissolution proportion of the first identification portion 12 in the actual product is greater than or equal to the preset dissolution proportion, the first identification portion 12 is judged to be in the second form; when the dissolution rate of the first identification portion 12 in the actual product is smaller than the preset dissolution rate, the first identification portion 12 is judged to be in the first form.
The insertion part of the present embodiment includes the insertion part body 11 and the first identification part 12, and since the first identification part 12 is made of a water-soluble material, when the first identification part 12 contacts with water, the first identification part 12 covering the outer surface of the insertion part body 11 is dissolved by the water and disappears. As can be seen, in the insertion portion of the present embodiment, when the insertion portion is first used, the insertion portion body 11 is covered with the first identification portion 12; when it is not used for the first time, the insertion part is inserted into a human body or is sterilized, and then is necessarily contacted with water, so that the first marking part 12 covered outside the insertion part body 11 is eliminated.
Therefore, in the insertion portion of this embodiment, whether the insertion portion is used for the first time can be determined by visually observing whether the outer surface of the insertion portion body 11 is covered with the first identification portion 12, and in the first aspect, the structure can be directly identified by a detector, so that the determination difficulty is low; the outer surface of the insertion part body 11 is only provided with two cases of covering the first identification part 12 and not covering the first identification part 12, so that the judgment result is objective and accurate, the reliability of the judgment result is ensured, and the use safety of the endoscope insertion part is ensured; on the other hand, if the insertion portion is not used for the first time, after the first identification portion 12 outside the insertion portion body 11 disappears, the change is irreversible, so that the accuracy of the judgment is not affected by the placement time, the judgment difficulty of the inspector can be further reduced, and the reliability of the judgment result can be further improved, so that the use safety of the endoscope insertion portion is further ensured. Namely, the insertion part of the embodiment solves the problem that the disposable endoscope in the related technology lacks a convenient and accurate scheme for judging the service condition.
The inspector in the embodiment of the application can be a medical staff or a detection system.
According to a preferred embodiment, the first identification layer 121 is provided on the first identification portion 12, and the first identification layer 121 is used to indicate the use state of the insertion portion body 11. Preferably, the first identification layer 121 is used to indicate that the insertion portion body 11 is in an unused state. Preferably, the first identification layer 121 may be an image layer, a text layer, a symbol layer, etc. For example: the first identification layer 121 is provided with a positive image, text, symbol, or the like, such as "v", "circle", "OK", "YES", "available", "safe", or the like, so as to present to the detector that the insertion portion body 11 is in an unused state, and is available this time. Fig. 5 shows a schematic view of a first identification layer 121 provided in a circular shape on the first identification portion 12. In the insertion portion according to the preferred embodiment of the present application, the first identification layer 121 is disposed on the first identification portion 12, and the first identification layer 121 is used for indicating the usage state of the insertion portion body 11, and by the indication effect of the first identification layer 121, the usage state of the insertion portion body 11 can be further prompted to the detector, so that the difficulty of determination can be further reduced, and the reliability of the determination result can be further improved. According to a preferred embodiment, the first marker 12 is located proximal to the active bending section 111 of the insertion body 11 and/or the first marker 12 is located distal to the passive bending section 112 of the insertion body 11, as shown in fig. 1-3. Preferably, the coverage area of the first identifier 12 may be determined according to actual needs, which is not limited herein. In the insertion part of the preferred technical solution of the present embodiment, the first identification part 12 is disposed at the proximal end of the active bending section 111 and/or the distal end of the passive bending section 112, and when the endoscope is held by hand, the hand will not normally contact the part, so as to avoid the hidden trouble of misjudgment caused by the dissolution of the first identification part 12 by the water on the hand; on the other hand, the portion is located at the distal end of the insertion portion 10, and the portion is more likely to be in contact with water when the insertion portion 10 is in use, so that the reliability of the judgment result can be further enhanced; in the third aspect, when the inspector is a medical care personnel, the inspector can identify the first identification part 12 with naked eyes, when the inspector is a system, the system can identify the first identification part 12 by using the camera module 14 on the insertion part 10, and the first identification part 12 is arranged at the near end of the active bending section 111 and/or the far end of the passive bending section 112, so that after the insertion part body 11 is bent, the first identification part 12 can be positioned in the shooting range of the camera module 14.
According to a preferred embodiment, the insertion part further comprises a second identification part 13, the second identification part 13 covers the outer surface of the insertion part body 11, when the first identification part 12 is in the first form, the first identification part 12 covers the surface of the second identification part 13, and when the first identification part 12 is in the second form, the first identification part 12 is dissolved and the second identification part 13 is exposed, as shown in fig. 6 and 7. Fig. 6 shows a schematic view of the first identification portion 12 covering the surface of the second identification portion 13, and fig. 7 shows a schematic view of the first identification portion 12 being dissolved and exposing the second identification portion 13. Preferably, the first identification portion 12 is provided with a receiving groove 123, and the receiving groove 123 is used for receiving the second identification portion 13, as shown in fig. 8. It can be seen that the second marker 13 is made of a water insoluble material. Preferably, the color of the second marking portion 13 may be visually distinguished from the color of the outer surface of the insertion portion body 11 for the convenience of observation.
