DETAILED DESCRIPTION

[0025] In the related art, in order to improve the cleaning and disinfecting effect on the interface to be cleaned, two cleaning pipes are used to be connected with the handle of the endoscope, one of which is in communication with the inside of the interface to be cleaned, and is used to clean and disinfect the inside of the interface to be cleaned and the inside of the handle of the endoscope, and the other is aligned with the outer wall of the interface to be cleaned, and is used to flush the outer wall of the interface to be cleaned. Although this cleaning method can clean the inside of the interface to be cleaned and the outer wall of the interface to be cleaned at the same time, on the one hand, the cleaning pipe is increased, and the control difficulty is increased accordingly, and on the other hand, the outlet of the cleaning pipe can only cover part of the outer wall of the interface to be cleaned, and cannot cover the whole, and the cleaning effect on the outer wall of the interface to be cleaned is also not good.

[0026] Therefore, the embodiments of the present application provide a connector 10, as shown in FIGS. 1-10, which is applied to an endoscope cleaning and disinfecting device, and is used to connect the interface to be cleaned 31 on the handle 30 of the endoscope. While cleaning and disinfecting the inside of the interface to be cleaned 31 and the inside of the handle 30 of the endoscope, the outer wall of the interface to be cleaned 31 is cleaned and disinfected by using the rotating part 200.

[0027] The connector 10 includes a shell 100 and a rotating part 200. The shell 100 includes a first channel 110 and a second channel 120. The first channel 110 is used to communicate with the interface to be cleaned 31. The cleaning pipe 20 is directly communicated with the shell 100. Part of the cleaning liquid in the cleaning pipe 20 enters the first channel 110, and the other part enters the second channel 120. The cleaning liquid is directly divided in the shell 100, and two cleaning pipes 20 are not needed, which reduces the corresponding operation difficulty. In the case that the first channel 110 is communicated with the interface to be cleaned 31, the cleaning liquid entering the second channel 120 flows towards the interface to be cleaned 31, and cleans the outer wall of the interface to be cleaned 31.

[0028] The rotating part 200 is rotatably installed in the shell 100, and the rotating part 200 is arranged around the first channel 110. In the case that the first channel 110 is communicated with the interface to be cleaned 31, the rotating part 200 is also arranged around the interface to be cleaned 31. The rotating part 200 has a liquid storage groove 210, the opening of the liquid storage groove 210 is arranged towards the second channel 120, and is communicated with the liquid outlet of the second channel 120, and is used to receive the cleaning liquid flowing out of the second channel 120. The groove wall of the liquid storage groove 210 close to the first channel 110 is provided with a cleaning hole 220, and the cleaning liquid in the liquid storage groove 210 can flow into the cleaning hole 220 and flow out of the cleaning hole 220, so that the outer wall of the interface to be cleaned 31 can be cleaned.

[0029] The first channel 110 and the second channel 120 in the shell 100 are used as flow channels for the cleaning liquid to flow through. In some embodiments, as shown in FIGS. 5 and 6, the shell 100 is further provided with a mounting cavity 150, and the rotating member 200 is mounted in the mounting cavity 150. When the connector 10 is connected to the interface 31 to be cleaned on the handle 30 of the endoscope, the first channel 110 is in communication with the interior of the interface 31 to be cleaned, the interface 31 to be cleaned is located in the mounting cavity 150, and the rotating member 200 is sleeved outside the interface 31 to be cleaned, so as to clean the outer wall of the interface 31 to be cleaned. The rotating member 200 and the mounting cavity 150 are both annular structures, the mounting cavity 150 provides a rotating space for the rotating member 200, and the mounting cavity 150 is in communication with the second channel 120, so that the liquid storage groove 210 is in communication with the second channel 120.

[0030] In the second channel 120 and the cleaning hole 220, the projection of the outlet axis of at least one of them on the cross section of the connector 10 avoids the axis of the rotating member 200, so that the rotating member 200 can rotate relative to the shell 100 under the impact of the liquid flowing through the second channel 120 and / or the cleaning hole 220.

[0031] After the cleaning liquid flows out of the second channel 120 and / or the cleaning hole 220, it continues to flow along the axis direction of the outlet. Since the outlet axis avoids the axis of the rotating member 200, the cleaning liquid flowing out of the outlet will not flow towards the axis of the rotating member 200, but will be offset radially relative to the rotating member 200. Therefore, the flow direction of the cleaning liquid can be divided into a radial component along the rotating member 200 and a tangential component along the rotating member 200, and the two components are perpendicular to each other, and the radial component can be zero.

[0032] Since the cleaning liquid has a tangential component along the rotating member 200, under the impact of the cleaning liquid, the rotating member 200 can be driven to rotate relative to the shell 100. After the rotating member 200 rotates, the cleaning hole 220 on the rotating member 200 can rotate around the interface 31 to be cleaned, so that the outer wall of the interface 31 to be cleaned can be washed by the cleaning liquid, thereby fully washing the outer wall of the interface 31 to be cleaned and improving the cleaning and disinfection effect of the interface 31 to be cleaned.

[0033] The tangential component of the rotating member 200 can be tangent to the inner wall of the liquid storage groove 210 of the rotating member 200. The cleaning liquid output from the second channel 120 has a tangential component to the inner wall of the liquid storage groove 210, and the rotating member 200 can rotate under the impact of this part of the liquid. The tangential component of the rotating member 200 can also be tangent to the inner wall of the rotating member 200. The inner wall of the rotating member 200 is the inner wall of the rotating member 200 close to the first channel 110. After the cleaning liquid is output from the cleaning hole 220, it has a tangential component to the inner wall of the rotating member 200, and the rotating member 200 can rotate under the impact of this part of the liquid.

[0034] The projection of the outlet axis of the second channel 120 and the cleaning hole 220 on the cross section of the connector 10 can simultaneously avoid the axis of the rotating member 200. The liquid flowing out of the second channel 120 and the liquid flowing out of the cleaning hole 220 can simultaneously impact the rotating member 200 to rotate. Only the projection of the second channel 120 on the cross section of the connector 10 can avoid the axis of the rotating member 200, and the liquid flowing out of the second channel 120 can impact the rotating member 200 to rotate. Only the projection of the cleaning hole 220 on the cross section of the connector 10 can avoid the axis of the rotating member 200, and the liquid flowing out of the cleaning hole 220 can impact the rotating member 200 to rotate.

[0035] The second channel 120 cooperates with the liquid storage groove 210 and the cleaning hole 220, and the cleaning liquid flows from the cleaning hole 220 to the outer wall of the interface 31 to be cleaned, thereby washing the outer wall of the interface 31 to be cleaned. Cooperate with the rotating movement of the rotating member 200 to clean the wall surface of the interface 31 to be cleaned in the circumferential direction. Because the cleaning liquid stored in the liquid storage groove 210 can rotate with the rotating member 200, after the cleaning liquid is sprayed from the cleaning hole 220, the cleaning liquid also has a certain centrifugal force, and the impact effect of the cleaning liquid is better, and the cleaning effect of the outer wall of the interface 31 to be cleaned is also better. In the case where the projection of the cleaning hole 220 on the cross section of the connector 10 avoids the axis of the rotating member 200, the liquid sprayed from the cleaning hole 220 impacts the outer wall of the interface 31 to be cleaned, and the impact direction is inclined to the radial direction of the interface 31 to be cleaned. This part of the liquid also has a tangential component to the outer wall of the interface 31 to be cleaned, and compared with the vertical impact to the outer wall of the interface 31 to be cleaned, the cleaning and disinfection effect of the cleaning liquid inclined to the interface 31 to be cleaned is better.

[0036] The cleaning liquid is only liquid in general, which can be liquid with only cleaning effect, liquid with only disinfection effect, liquid with both cleaning and disinfection effects, or liquid with other effects.

[0037] The rotating member 200 is generally made of light material with low density to reduce the overall weight of the rotating member 200, thereby reducing the driving force required for the rotating member 200 to rotate and making the rotating member 200 easier to rotate. In some preferred embodiments, the rotating member 200 is rotatably connected to the housing 100 via bearings to reduce the friction between the rotating member 200 and the housing 100, thereby making the rotating member 200 rotate more smoothly.

[0038] In some preferred embodiments, the second channel 120 is arranged around the first channel 110, and the cleaning liquid output from the liquid outlet of the second channel 120 can flow uniformly into the liquid storage tank 210, so that the cleaning liquid can be sprayed more uniformly from the cleaning hole 220.

[0039] In some embodiments, the outlet axis of the cleaning hole 220 is arranged obliquely relative to the cross section of the connector 10, and the outlet axis of the cleaning hole 220 does not lie on the cross section of the connector 10. The outlet axis of the cleaning hole 220 is arranged to extend towards the liquid inlet of the first channel 110. After the cleaning liquid is sprayed from the cleaning hole 220, it is sprayed towards the liquid inlet of the first channel 110 and then impacts on the outer wall of the interface 31 to be cleaned and gradually flows down from the outer wall. In this way, the cleaning liquid can flow through more areas of the interface 31 to be cleaned, thereby improving the utilization rate of the cleaning liquid.

[0040] When the connector 10 is connected to the interface 31 to be cleaned, the first channel 110 is inserted into the interface 31 to be cleaned, and the outer wall of the first channel 110 is in contact with the interface 31 to be cleaned, and a connection gap is formed therebetween. In some embodiments of the present application, the outlet axis of the cleaning hole 220 is directed towards the connection gap between the outer wall of the first channel 110 and the interface 31 to be cleaned, so that the cleaning liquid flowing out of the cleaning hole 220 can enter the interface 31 to be cleaned through the connection gap, thereby flushing the wall surface of the interface 31 to be cleaned which is in contact with the outer wall of the first channel 110 and discharging part of the cleaning liquid through the interface 31 to be cleaned.

[0041] In some embodiments, the outlet axis of at least one cleaning hole 220 can lie on the cross section of the connector 10, and the cleaning hole 220 directly corresponds to the connection gap, so that the cleaning liquid sprayed from the cleaning hole 220 can directly enter the connection gap. However, this structure has a requirement for the position of the cleaning hole 220. For the cleaning hole 220 located below the connection gap, the outlet axis of the cleaning hole 220 needs to be arranged obliquely relative to the cross section of the connector 10, and the outlet axis of the cleaning hole 220 is arranged to extend towards the liquid inlet of the first channel 110, so that the liquid sprayed from the cleaning hole 220 can enter the connection gap between the outer wall of the first channel 110 and the interface 31 to be cleaned to clean the inner wall of the interface 31 to be cleaned.

[0042] The cleaning holes 220 can be provided in plurality, and the plurality of cleaning holes 220 are distributed along the circumference of the rotating member 200, so as to improve the ejection port of the cleaning liquid, and make the stress of each part of the rotating member 200 in the rotating process as balanced as possible. In some preferred embodiments, the cleaning holes 220 are divided into multiple rows, and the multiple rows of cleaning holes 220 are distributed along the circumference of the rotating member 200, and each row of cleaning holes 220 includes multiple cleaning holes 220 arranged along the axial direction of the rotating member 200.

[0043] In some embodiments, the shell 100 has multiple diversion plates 130 fixed to the second channel 120, as shown in FIG. 1 and FIG. 3 to FIG. 6. The multiple diversion plates 130 are distributed along the circumference of the second channel 120, and a liquid channel is formed between two adjacent diversion plates 130. The cleaning liquid entering the second channel 120 is diverted through the multiple liquid channels. The projection of the outlet axis of the liquid channel on the cross section of the connector 10 avoids the axis of the rotating member 200. After passing through the liquid channel, the cleaning liquid enters the liquid storage groove 210 and drives the rotating member 200 to rotate.

[0044] The cleaning liquid entering the first channel 110 can clean the inside of the interface 31 to be cleaned, and the cleaning liquid entering the second channel 120 can flow through the liquid storage groove 210 and the cleaning hole 220 in sequence to clean the outer wall of the interface 31 to be cleaned. Part of the cleaning liquid ejected from the cleaning hole 220 can enter the connection gap between the outer wall of the first channel 110 and the interface 31 to be cleaned, and flush the wall of the interface 31 to be cleaned in contact with the outer wall of the first channel 110. However, due to the clamping connection between the first channel 110 and the interface 31 to be cleaned, the cleaning liquid cannot enter and clean the part where the wall of the interface 31 to be cleaned and the outer wall of the first channel 110 are closely attached.

[0045] Therefore, in some embodiments, a flow guide groove 140 is directly arranged on the outer wall of the first channel 110, as shown in FIG. 3, FIG. 5 and FIG. 6. When the first channel 110 is inserted into the inside of the interface 31 to be cleaned, the flow guide groove 140 can connect the inside of the interface 31 to be cleaned and the cleaning hole 220, as shown in FIG. 4, so that the cleaning liquid in the cleaning hole 220 can flow into the inside of the interface 31 to be cleaned. After the cleaning liquid enters the flow guide groove 140, it can clean the wall of the interface 31 to be cleaned corresponding to the flow guide groove 140, and after the cleaning liquid flows out of the flow guide groove 140, it can enter the inside of the interface 31 to be cleaned and be discharged from the inside of the interface 31 to be cleaned.

[0046] In specific implementation, the inlet of the flow guide groove 140 is located inside the shell 100, and the outlet is located inside the interface 31 to be cleaned. The cleaning liquid sprayed from the cleaning hole 220 enters the inlet of the flow guide groove 140, then flows through the flow guide groove 140, washes the groove wall of the flow guide groove 140 and the inner wall of the interface 31 to be cleaned corresponding to the flow guide groove 140, and then flows out from the outlet of the flow guide groove 140 and enters the interface 31 to be cleaned, and is discharged from the interface 31 to be cleaned.

[0047] In some preferred embodiments, the flow guide groove 140 is arranged to extend spirally around the axis of the first channel 110, thereby increasing the length of the flow guide groove 140 and the inner wall area of the interface 31 to be cleaned corresponding to the flow guide groove 140. At the same time, since the flow guide groove 140 is arranged to extend spirally, the cleaning liquid sprayed from the flow guide groove 140 can rotate around the axis of the interface 31 to be cleaned when entering the interface 31 to be cleaned, thereby improving the cleaning effect on the inside of the interface 31 to be cleaned.

[0048] In addition, a plurality of flow guide grooves 140 can be arranged, and the increase in the number of flow guide grooves 140 can also increase the inner wall area of the interface 31 to be cleaned corresponding to the flow guide groove 140. In addition, the plurality of flow guide grooves 140 are uniformly distributed along the circumference of the first channel 110, so that the liquid entering the flow guide grooves 140 from all around the circumference of the first channel 110 can be balanced as much as possible.

[0049] In the case where the flow guide groove 140 is arranged to extend spirally around the axis of the first channel 110, and the projection of the outlet axis of the cleaning hole 220 on the cross section of the connector 10 avoids the axis of the rotating member 200, the avoidance direction of the outlet axis of the cleaning hole 220 to the axis of the rotating member 200 is opposite to the surrounding direction of the flow guide groove 140 to the axis of the first channel 110. That is, if the outlet axis of the cleaning hole 220 avoids the axis of the rotating member 200 by shifting to one side, the flow guide groove 140 is arranged to surround the axis of the first channel 110 on the other side, and the rotating member 200 can rotate around the first channel 110, and the two are coaxially arranged. After the cleaning liquid sprayed from the cleaning hole 220 enters the flow guide groove 140, the flow direction of the cleaning liquid is opposite to the flow direction caused by inertia, and the cleaning liquid will be disturbed and stay, thereby improving the cleaning effect on the inner wall of the interface 31 to be cleaned.

[0050] In some embodiments, the rotating member 200 is provided with a stepped portion 230, which divides the liquid storage groove 210 into a first liquid storage space 211 and a second liquid storage space 212. The first liquid storage space 211 is arranged close to the liquid outlet of the second channel 120, and the second liquid storage space 212 is arranged away from the liquid outlet of the second channel 120. The liquid flow cross-sectional area of the first liquid storage space 211 is greater than that of the second liquid storage space 212.

[0051] After the cleaning liquid flows out of the liquid outlet of the second channel 120, it flows into the liquid storage groove 210. Due to the presence of the stepped portion 230, part of the liquid will impact the stepped portion 230, the contact area between the cleaning liquid and the rotating member 200 increases, the impact of the cleaning liquid on the rotating member 200 also increases, and the rotating member 200 is more easily rotated.

[0052] The application also provides a cleaning method using the connector 10 provided with the flow guide groove 140.

[0053] S1: connecting the connector 10 with the to-be-cleaned interface 31 of the endoscope handle 30, wherein the first channel 110 is in communication with the inside of the to-be-cleaned interface 31, and the rotating member 200 is sleeved outside the to-be-cleaned interface 31;

[0054] S2: starting the endoscope cleaning and disinfecting equipment, and introducing the cleaning liquid into the connector 10 through the cleaning pipe 20, part of the cleaning liquid entering the inside of the to-be-cleaned interface 31 through the first channel 110, and part of the cleaning liquid entering the second channel 120, the liquid storage groove 210 and the cleaning hole 220 in sequence, thereby cleaning the outer wall of the to-be-cleaned interface 31, wherein part of the cleaning liquid flowing out of the cleaning hole 220 enters the flow guide groove 140, thereby cleaning the inner wall of the to-be-cleaned interface 31 corresponding to the flow guide groove 140;

[0055] S3: after the cleaning liquid is introduced for a preset time, rotating the connector 10 at a preset angle, and replacing the inner wall of the to-be-cleaned interface 31 corresponding to the flow guide groove 140.

[0056] When the connector 10 is rotated, the endoscope cleaning and disinfecting equipment can be closed to stop the introduction of the cleaning liquid, so that the connector 10 is more easily controlled. Alternatively, the connector 10 can be rotated without closing the endoscope cleaning and disinfecting equipment, which can save operation steps and cleaning time.

[0057] In the case where the flow guide groove 140 is only provided with one, the connector 10 needs to be rotated multiple times to completely clean the inner wall of the to-be-cleaned interface 31. In some preferred embodiments, the flow guide groove 140 has multiple, so that the number of rotations of the connector 10 can be correspondingly reduced. Meanwhile, if the multiple flow guide grooves 140 are uniformly distributed along the circumference of the first channel 110, the number of rotations of the connector 10 can be further reduced.

[0058] The application also provides a cleaning pipe set, which comprises the connector 10 provided in any of the above embodiments.

[0059] The embodiment of the present application further provides an endoscope cleaning and disinfecting device comprising the cleaning tube set provided by the above embodiment. Referring to FIGS. 9 and 10, the connecting head 10 is connected with the cleaning interface 31 on the endoscope handle 30, and the cleaning interface 31 is cleaned.

[0060] Referring to FIG. 10, after the connecting head 10 is connected with the cleaning interface 31, the end of the shell abuts against the endoscope handle 30, so that the liquid flowing out of the cleaning hole 220 is prevented from escaping everywhere. Generally, an outlet for the cleaning liquid flowing out is arranged at the bottom of the shell, so that the used cleaning liquid is collected and discharged. Meanwhile, the rotating member 200 and the endoscope handle 30 have a gap therebetween, so that the friction between the rotating member 200 and the endoscope handle 30 does not affect the normal rotation of the rotating member 200.

[0061] The endoscope cleaning and disinfecting device provided by the embodiment of the present application can clean various types of endoscopes, including a sputum suction mirror, a bronchoscope, a nephroscope, an esophagoscope, a gastroscope, a colonoscope, an otoscope, a nasoscope, an oral mirror, a laryngoscope, a colposcope, a laparoscope, an arthroscope, etc.
