One end of the cleaning tube is connected to the channel port on the endoscope handle, and the other end is connected to the cleaning nozzle of the cleaning and disinfection equipment. However, during the cleaning and disinfection process of the endoscope, the connection between the cleaning tube and the endoscope is prone to leakage, which affects the cleaning and disinfection effect of the endoscope. Utility Model Content

[0004] The purpose of this application is to provide a connector, a cleaning assembly and an endoscope cleaning and disinfection device to solve the above-mentioned technical problems existing in the prior art.

[0005] This application is implemented as follows:

[0006] In the first aspect, an embodiment of the present application provides a connecting head, which is used in an endoscope cleaning and disinfection device.

DETAILED DESCRIPTION

[0024] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only used as examples, not to limit the present invention.

[0025] In the related art, the liquid outlet of the cleaning tube is connected to the endoscope handle through a connector, so as to clean the channel in the endoscope handle. However, in actual use, the cleaning liquid is prone to leakage at the connection portion between the cleaning tube and the connector.

[0026] The inventor has found that the connector and the cleaning tube are usually made of flexible materials, and part of the connector is inserted into the cleaning tube and bonded to the cleaning tube. When the operator controls the position of the cleaning tube and the connector, the connector and the cleaning tube are easily deformed under the action of external force, and the deformed part of the connector or the cleaning tube is stretched or compressed, causing the part where the connector and the cleaning tube are connected to be pulled, and the bonded part between the two is easily separated after being pulled. Therefore, the cleaning liquid is easily leaked at the place where the connector and the cleaning tube are connected.

[0027] In view of this, the present application embodiment provides a connector 200, which is applied to an endoscope cleaning and disinfection device, referring to Figures 1 to 5As shown, the connector 200 includes a first connector 210 and a second connector 220. The first connector 210 is used to connect to the cleaning tube 100, and the second connector 220 is used to connect to the endoscope handle 400. One end of the first connector 210 is inserted into the cleaning tube 100 and fixedly connected to the cleaning tube 100. The other end of the first connector 210 is inserted into the second connector 220 and fixedly connected to the second connector 220. Figure 1 and Figure 4 The end of the second connector 220 away from the first connector 210 is inserted into the endoscope handle 400 and connected to the endoscope handle 400.

[0028] Channels are provided inside the first connector 210 and the second connector 220. When the two are connected to each other and are respectively connected to the cleaning tube 100 and the endoscope handle 400, the channels inside the first connector 210 and the second connector 220 can connect the cleaning tube 100 and the endoscope handle 400 to transfer the cleaning fluid in the cleaning tube 100 to the endoscope handle 400 to clean the endoscope handle 400.

[0029] The endoscope handle 400 has a plurality of channels, such as an instrument channel, a suction valve channel, etc. The second connector 220 can be inserted from the instrument mouth of the endoscope handle 400, or inserted from the opening of the suction valve body, to achieve the connection between the second connector 220 and the endoscope handle 400, so that the cleaning tube 100 corresponding to the second connector 220 can be connected to the instrument channel or the suction valve channel. Cleaning and disinfecting the endoscope handle 400 is actually cleaning and disinfecting the channels in the endoscope handle 400. The end of the cleaning tube 100 away from the first connector 210 is connected to the endoscope cleaning and disinfecting device, and the endoscope cleaning and disinfecting device transports cleaning liquid into the cleaning tube 100.

[0030] The first joint 210 and the second joint 220 have different rigidities, and the rigidity of the first joint 210 is greater than that of the second joint 220. Compared with the connector 200 of the prior art, the rigidity of the first joint 210 is improved, and the first joint 210 has a stronger supporting effect on the cleaning tube 100. Even if squeezed by an external force, the cleaning tube 100 will not collapse and deform inwardly. Therefore, the connection between the cleaning tube 100 and the first joint 210 will not be pulled against each other, and the structure of the cleaning tube 100 will not be stretched or compressed. In this way, the connection stability between the cleaning tube 100 and the first joint 210 can be improved, and a gap between the connection parts of the two can be avoided, which may cause leakage of the cleaning liquid.

[0031] The rigidity of the second connector 220 is less than that of the first connector 210, and its structure is relatively soft. When the second connector 220 is inserted into the endoscope handle 400, the second connector 220 is more easily deformed by force and is more easily inserted into the endoscope handle 400. In addition, since the second connector 220 is more easily deformed, it can be pressed against the inner wall of the endoscope handle 400, and the fit is more closely, thereby improving the sealing between the two.

[0032] The first connector 210 is inserted into the second connector 220, and the first connector 210 can support the second connector 220. Even if the operator holds the second connector 220 outside, the second connector 220 will not collapse and deform toward the inside under the action of the holding force, thereby avoiding the occurrence of a gap at the connection point between the first connector 210 and the second connector 220, and avoiding the occurrence of leakage in the connector 200 due to the division of the connector 200 into two parts, the first connector 210 and the second connector 220. At the same time, since part of the first connector 210 can support the second connector 220, the force point of the second connector 220 is stable during the holding of the second connector 220, and it is easier to hold it outside the second connector 220, and the force point of the connector 200 will not be unstable and difficult to hold due to the low overall rigidity of the connector 200.

[0033] In some preferred embodiments, the first joint 210 is provided with an annular protrusion 211 on the outer fixed sleeve, and the annular protrusion 211 is located outside the second joint 220, and is used to block the end surface of the second joint 220 close to the first joint 210 and the end surface of the cleaning pipe 100 connected to the first joint 210, Figure 1 , Figure 2 as well as Figure 4 As shown. The annular protrusion 211 blocks between the cleaning tube 100 and the second joint 220. Even if the cleaning tube 100 or the second joint 220 is deformed under the action of external force, the deformation degree will be reduced due to the abutment of the annular protrusion 211. The second joint 220 directly abuts against the annular protrusion 211. In the process of plugging the second joint 220 into the endoscope handle 400, the second joint 220 and the endoscope handle 400 abut against the force. Since the other end of the annular protrusion 211 is provided, the annular protrusion 211 bears the force transmitted by the second joint 220, thereby preventing the force transmitted by the second joint 220 from directly acting on the cleaning tube 100, thereby affecting the connection stability between the cleaning tube 100 and the first joint 210.

[0034] The size of the annular protrusion 211 should not be too small. Preferably, the outer diameter of the annular protrusion 211 is larger than the outer diameter of the cleaning tube 100 corresponding to the first joint 210, so as to ensure that the end surface of the cleaning tube 100 close to the first joint 210 can be completely abutted against the annular protrusion 211. On the one hand, the annular protrusion 211 has a better abutting effect on the cleaning tube 100, and on the other hand, it can prevent the external force from abutting against the end surface of the cleaning tube 100 and causing damage to the end structure of the cleaning tube 100.

[0035] The size of the annular protrusion 211 should not be too large. Preferably, the outer diameter of the annular protrusion 211 is smaller than the outer diameter of the end face of the second joint 220 close to the first joint 210, so as to ensure that the end face of the annular protrusion 211 close to the second joint 220 can all abut against the end face of the second joint 220. If the size of the annular protrusion 211 is too large, the annular protrusion 211 is protruding relative to the second joint 220, which will affect the operator's grip on the second joint 220 and the operating feel of the second joint 220. At the same time, if the size of the annular protrusion 211 is too large, the manufacturing cost of the first joint 210 will also increase.

[0036] The annular protrusion 211 may be circular, elliptical, or other irregular annular structures, which are not specifically limited in the embodiments of the present application. In the end face of the second joint 220 close to the first joint 210, the first joint 210 refers to the portion of the first joint 210 exposed to the second joint 220, and does not represent the first joint 210 located inside the second joint 220. Therefore, the end face of the second joint 220 close to the first joint 210 refers to the end face of the second joint 220 adjacent to the portion of the first joint 210 exposed to the second joint 220.

[0037] In some embodiments of the present application, the first connector 210 and the second connector 220 are engaged with each other. Specifically, a plurality of engaging protrusions 212 are provided on the outer peripheral wall of the first connector 210. Figure 2 A plurality of snap-in grooves 221 are provided on the inner peripheral wall of the second joint 220, Figure 3 and Figure 5 As shown. The snap-fit ​​protrusions 212 and the snap-fit ​​grooves 221 are arranged in a one-to-one correspondence. When the first connector 210 is plugged into the second connector 220, the snap-fit ​​protrusions 212 are snap-fitted into the corresponding snap-fit ​​grooves 221. Figure 7 and Fig.10 As shown, the connection stability between the first connector 210 and the second connector 220 is improved.

[0038] The clamping protrusion 212 is provided on the first joint 210, and has a high rigidity, and the clamping groove 221 is provided on the second joint 220. In the process of inserting the first joint 210 into the second joint 220, the inner wall of the second joint 220 is more easily deformed to allow the clamping protrusion 212 to pass through, until the clamping protrusion 212 is clamped into the corresponding clamping groove 221. A portion of the inner wall of the second joint 220 is clamped between two adjacent clamping protrusions 212, and due to the clamping of the clamping protrusion 212, the structure of the portion of the second joint 220 is not easily deformed, so it is more difficult for the first joint 210 to be separated from the second joint 220, and the first joint 210 can be connected to the second joint 220 more stably. If the snap-fit ​​protrusion 212 is provided on the second joint 220 and the snap-fit ​​groove 221 is provided on the first joint 210, the snap-fit ​​protrusion 212 is more likely to be deformed due to the lower rigidity of the second joint 220. Under the action of external force, it is less difficult for the snap-fit ​​protrusion 212 to deform to form a channel for the first joint 210 to detach from the second joint 220, and the connection between the first joint 210 and the second joint 220 is not stable.

[0039] In some preferred embodiments, the size of the clamping protrusion 212 can be limited to reduce the difficulty of inserting the clamping protrusion 212 into the second connector 220 while ensuring the connection stability between the first connector 210 and the second connector 220. Figure 2 As shown, along the plugging direction of the first connector 210 to the second connector 220, the outer diameter of the corresponding clamping protrusion 212 gradually decreases. Corresponding to the clamping protrusion 212, the size of the clamping groove 221 that is closer to the opening of the second connector 220 and plugged with the first connector 210 is larger, referring to Figure 3 and Figure 5 shown.

[0040] During the process of plugging the first connector 210, the smaller clamping protrusion 212 is first inserted into the second connector 220. The smaller the size of the clamping protrusion 212, the smaller the deformation of the second connector 220 to adapt to the clamping protrusion 212 when inserted into the second connector 220. At the same time, since the size of the clamping groove 221 closer to the opening of the second connector 220 is larger, the smaller clamping protrusion 212 is plugged into the larger clamping groove 221, and the deformation of the second connector 220 is further reduced, thereby further reducing the difficulty of plugging the first connector 210 into the second connector 220.

[0041] In some preferred embodiments of the present application, the groove wall of at least one snap-fit ​​groove 221 is located on the rotation path of its corresponding snap-fit ​​protrusion 212 rotating around the axis of the first joint 210, so that it can cooperate with the snap-fit ​​protrusion 212 in the circumferential direction of the snap-fit ​​protrusion 212 to prevent the rotation of the snap-fit ​​protrusion 212, thereby fixing the relative positions of the first joint 210 and the second joint 220 in the circumferential direction and improving the connection stability between the first joint 210 and the second joint 220.

[0042] The snap-fitting protrusion 212 is provided on the first joint 210, so the circumference of the first joint 210 can be used as the circumference of the snap-fitting protrusion 212. The snap-fitting groove 221 cooperates with the snap-fitting protrusion 212 in its circumferential limit position, which can prevent the snap-fitting protrusion 212 from rotating. Therefore, the structure of the snap-fitting protrusion 212 cannot be a rotating body structure, because the rotation path of the rotating body overlaps with its structure itself, and the groove wall of the snap-fitting groove 221 cannot limit it. In some specific embodiments, the side wall of the snap-fitting protrusion 212 is provided with a plane to cooperate with the groove wall of the snap-fitting groove 221 in limiting position, refer to Figure 2 shown.

[0043] The outer peripheral wall of the second joint 220 is provided with at least one anti-slip protrusion 222. Figure 1 and Figure 4 As shown, the anti-skid protrusion 222 can enhance the friction between the operator and the second joint 220, and prevent the operator's fingers from slipping on the second joint 220. In some preferred embodiments, part of the anti-skid protrusion 222 is located in the area where the second joint 220 is connected to the first joint 210. Figure 3 and Figure 7 With such a layout, when the operator holds the second connector 220 , the anti-slip protrusion 222 can enhance the friction force, and at the same time, the first connector 210 can support the second connector 220 , thereby preventing the operator from holding the second connector 220 unsteadily.

[0044] When the second connector 220 is connected to the endoscope handle 400, for different channels in the endoscope handle 400, the second connector 220 is connected to the channel in different ways according to the different channel structures. In some embodiments, the second connector 220 can be directly inserted into the endoscope handle 400, referring to Figure 8 In some other embodiments, the endoscope handle 400 is further provided with a third connector 410, and the connection between the second connector 220 and the endoscope handle 400 is actually the connection between the second connector 220 and the third connector 410. Fig.10 As shown, the second joint 220 is directly sleeved outside the third joint 410. Further preferably, the inner peripheral wall of the second structure is provided with a stop protrusion 223, referring to Figure 5As shown, the stop protrusion 223 can cooperate with the third joint 410 at the circumferential upper limit position of the second joint 220 to prevent the second joint 220 from rotating around its axis.

[0045] The present application also provides a cleaning assembly, including the connector 200 provided in any of the above embodiments, and also including a cleaning tube 100, wherein the two ends of the cleaning tube 100 are respectively a liquid inlet 110 and a liquid outlet. The liquid inlet 110 is used to connect to the cleaning nozzle of the endoscope cleaning and disinfection equipment, and the liquid outlet is connected to the first connector 210. Figures 6 to 11 shown.

[0046] According to the structure of the channel opening of the endoscope handle 400, different cleaning components corresponding to the second connector 220 are selected. Figure 8 As shown, the second connector 220 can be directly plugged into the channel opening, so you can choose Figure 6 and Figure 7 The cleaning assembly shown is inserted into the channel by the second connector 220, and the outer peripheral wall of the second connector 220 is pressed against the inner wall of the channel to complete the fixation of the second connector 220 and the endoscope handle 400. Fig.10 As shown, the channel opening of the endoscope handle 400 has a third connector 410, so it can be selected as follows Fig. 9 The cleaning assembly shown utilizes the second joint 220 to be sleeved on the outside of the third joint 410 to complete the fixation of the cleaning assembly and the endoscope handle 400.

[0047] The first joint 210 extends through the liquid outlet into the cleaning tube 100 and is fixed to the cleaning tube 100. In some preferred embodiments, in order to improve the connection stability between the cleaning tube 100 and the first joint 210, a clamping portion 213 may be provided at the position where the first joint 210 extends into the cleaning tube 100. Figure 2 , Figure 7 and Fig.10 As shown, the radial dimension of the clamping portion 213 is larger than the inner diameter of the cleaning tube 100, so that the clamping portion 213 can be clamped and matched with the cleaning tube 100. Preferably, the clamping portion 213 and the cleaning tube 100 are glued and matched to further improve the connection stability between the clamping portion 213 and the cleaning tube 100. In other preferred embodiments, along the plugging direction of the first joint 210 into the cleaning tube 100, the radial dimension of the clamping portion 213 gradually decreases. The clamping portion 213 that enters the cleaning tube 100 first is smaller in size, which makes it easier for the clamping portion 213 to enter the cleaning tube 100.

[0048] There can be multiple groups of cleaning components, and multiple groups of cleaning components can be connected to different cleaning channels of the endoscope handle 400 at the same time to flush different cleaning channels. Fig.11At the same time, in multiple groups of cleaning channels, the liquid inlets 110 of the cleaning tubes 100 can be connected through the three-way connector 300, and different cleaning tubes 100 can be connected to the cleaning nozzle of the endoscope cleaning and disinfection equipment through the three-way connector 300, so as to clean multiple channels at the same time.

[0049] An embodiment of the present application also provides an endoscope cleaning and disinfecting device, including the cleaning component provided by any of the above embodiments.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
