Description

Technical Field

[0001] The utility model belongs to the technical field of endoscope cleaning, and in particular relates to a pipe joint for endoscope cleaning, a cleaning component and endoscope cleaning and disinfecting equipment. Background Art

[0002] As a medical diagnostic device, an endoscope can enter the body and take images of lesions, providing doctors with sufficient diagnostic information to treat diseases.

[0003] During the cleaning and disinfection process of the endoscope, a cleaning tube is used to connect the endoscope and the cleaning nozzle. 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. The cleaning tube is generally connected to the cleaning nozzle through a pipe joint.

[0004] However, during the plugging process of the pipe joint and the cleaning nozzle, when the operator holds the pipe joint, the operator's fingers are likely to slip on the pipe joint, which is not conducive to applying force to the pipe joint. Utility Model Content

[0005] The purpose of the present application is to provide a pipe joint, a cleaning component and an endoscope cleaning and disinfection device for endoscope cleaning to solve the above-mentioned technical problems existing in the prior art.

[0006] This application is implemented as follows:

[0007] In the first aspect, an embodiment of the present application provides a pipe joint for cleaning an endoscope, the pipe joint comprising a first branch pipe and at least one second branch pipe which are interconnected, the first branch pipe being used to connect to an endoscope cleaning and disinfection device, and the second branch pipe being used to connect to a cleaning pipe; an annular baffle and at least one snap-in protrusion are fixed to the outer wall of the first branch pipe, the snap-in protrusion being used to snap into the endoscope cleaning and disinfection device, at least one snap-in protrusion being located on the side of the annular baffle plate close to the liquid inlet of the first branch pipe, and the radial dimension of the annular baffle plate is greater than the radial dimension of the snap-in protrusion.

[0020] 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.

[0021] The present application embodiment provides a pipe connector 10 for cleaning an endoscope, Figures 1 to 6 As shown, the pipe connector 10 includes a first branch pipe 100 and at least one second branch pipe 200 which are interconnected. The first branch pipe 100 is used to connect to the endoscope cleaning and disinfection device, and the second branch pipe 200 is used to connect to the cleaning pipe 20.

[0022] It can be understood that one end of the first branch pipe 100 is its liquid inlet, and the other end is its liquid outlet. The liquid inlet is used to be connected to the endoscope cleaning and disinfection device, specifically connected to the cleaning nozzle of the endoscope cleaning and disinfection device. The liquid inlet of the first branch pipe 100 is used to receive the cleaning liquid and / or disinfectant delivered from the endoscope cleaning and disinfection device, and the liquid outlet is used to communicate with the second branch pipe 200 to deliver the cleaning liquid and / or disinfectant inside it to the second branch pipe 200, so as to be transmitted to the cleaning pipe 20 connected to the second branch pipe 200.

[0023] At least one clamping protrusion 400 is fixed to the outer wall of the first branch pipe 100. The clamping protrusion 400 is used to clamp against the inner wall of the cleaning nozzle when the first branch pipe 100 is inserted into the cleaning nozzle of the endoscope cleaning and disinfecting device, thereby improving the connection stability between the first branch pipe 100 and the endoscope cleaning and disinfecting device. All the clamping protrusions 400 fixed to the outer wall of the first branch pipe 100 are located on the side of the annular baffle 300 close to the liquid inlet of the first branch pipe 100, so as to avoid the connection between the clamping protrusion 400 and the cleaning nozzle being affected by the obstruction of the annular baffle 300.

[0024] Moreover, the radial dimension of the annular baffle 300 is larger than the radial dimension of the clamping protrusion 400. It can be understood that when only one clamping protrusion 400 is provided on the outer wall of the first branch tube 100, the radial dimension of the clamping protrusion 400 is smaller than the radial dimension of the annular baffle 300; when two or more clamping protrusions 400 are provided on the outer wall of the first branch tube 100, the radial dimension of each clamping protrusion 400 is smaller than the annular baffle 300. In this way, when the operator holds the first branch tube 100, no matter which side of the annular baffle 300 the finger holds, even if the finger slips on the first branch tube 100, the finger will be limited by the annular baffle 300 to ensure that the operator can smoothly apply force to the first branch tube 100 and complete the smooth docking of the first branch tube 100 with the endoscope cleaning and disinfection device.

[0025] The radial dimension of the annular baffle 300 must be larger than the radial dimension of the clamping protrusion 400, so that even if the operator's finger slides over the clamping protrusion 400, it can be blocked by the annular baffle 300. If the radial dimension of the annular baffle 300 is the same as that of the clamping protrusion 400, the finger can easily slide directly over the annular baffle 300 when sliding over the clamping protrusion 400, and the annular baffle 300 cannot play the role of a limit stop.

[0026] The second branch pipe 200 is a branch pipe, which is connected to the cleaning pipe 20. Figure 5 As shown, the other end of the cleaning tube 20 is connected to the channel in the endoscope handle 30, referring to Figure 6 The number of the second branch tubes 200 can be one, two or three, which can be determined according to the number of channels in the endoscope handle 30 that need to be cleaned. Generally, the number of the second branch tubes 200 is the same as the number of channels in the endoscope handle 30, so as to achieve the purpose of cleaning all the channels to be cleaned in the endoscope handle 30 at one time, thereby improving the cleaning efficiency.

[0027] In some preferred embodiments, the radial dimension of the annular baffle 300 is greater than or equal to 1.5 times the maximum radial dimension of the snap-fit ​​protrusion 400 , and an obvious size difference is formed between the annular baffle 300 and the snap-fit ​​protrusion 400 to improve the stopping effect of the annular baffle 300 .

[0028] The annular baffle 300 may be an integral annular structure or an annular structure formed by a plurality of protrusions. Since the annular baffle 300 mainly serves as a stopper, the annular baffle 300 is generally an integral annular structure to improve its structural strength. Further preferably, the annular baffle 300 is integrally formed with the first branch pipe 100 to optimize the manufacturing steps of the pipe joint 10 and improve production efficiency.

[0029] There can be multiple clamping protrusions 400, and the maximum radial dimension of each clamping protrusion 400 is different to match cleaning nozzles of different sizes. It should be noted that the shape of a clamping protrusion 400 is not necessarily regular, and it can have different radial dimensions, among which the largest value is its maximum radial dimension. Along the direction from the liquid inlet of the first branch pipe 100 to the annular baffle 300, the maximum radial dimension of the clamping protrusion 400 gradually increases, referring to Figures 1 to 4 As shown. The closer to the annular baffle 300, the larger the size of the clamping protrusion 400, and the larger the size of the corresponding cleaning nozzle. The smaller clamping protrusion 400 at the front side will not affect the larger clamping protrusion 400 at the rear side to connect to the corresponding cleaning nozzle, which can avoid the obstruction caused by the size difference of the clamping protrusion 400 to the connection between the first branch pipe 100 and the cleaning nozzle.

[0030] The clamping protrusion 400 is an annular structure, so as to seal the connection portion between the first branch pipe 100 and the cleaning nozzle in the circumferential direction thereof, thereby preventing leakage of cleaning liquid from occurring in the connection gap between the two.

[0031] In order to further improve the convenience of inserting the clamping protrusion 400 into the cleaning nozzle, in some preferred embodiments, along the direction from the liquid inlet of the first branch pipe 100 to the annular baffle 300, the radial size of at least part of any clamping protrusion 400 gradually increases, referring to Figures 1 to 4 As shown. The clamping protrusion 400 corresponding to the cleaning nozzle first enters the cleaning nozzle with a smaller radial dimension, which is easier to enter the cleaning nozzle, and the larger part enters the cleaning nozzle later and is clamped with the cleaning nozzle. In addition, since the radial dimension of the clamping protrusion 400 is gradually increased, the outer surface of the clamping protrusion 400 can form a guide surface to guide the clamping protrusion 400 to be inserted into the cleaning nozzle.

[0032] In some embodiments, a reinforcing rib 500 is connected to one side of the annular baffle 300 near the liquid inlet of the first branch pipe 100. The reinforcing rib 500 is fixed between the annular baffle 300 and the outer wall of the first branch pipe 100 to improve the connection strength between the annular baffle 300 and the first branch pipe 100, so that the annular baffle 300 can withstand a stronger force and has a better limit stop effect. Preferably, along the direction from the annular baffle 300 to the liquid inlet of the first branch pipe 100, the height of the reinforcing rib 500 in the radial direction of the first branch pipe 100 gradually decreases, referring to Figures 1 to 4 On the one hand, the material of the reinforcing rib 500 can be saved, and on the other hand, the discomfort caused by the reinforcing rib 500 to the operating feel can be reduced.

[0033] In other embodiments, a reinforcing rib 500 is connected to one side of the annular baffle 300 close to the second branch pipe 200, and the reinforcing rib 500 is fixed to the outer wall of the first branch pipe 100, and the radial dimension of the reinforcing rib 500 in the first branch pipe 100 gradually decreases along the direction from the annular baffle 300 to the second branch pipe 200.

[0034] Along the axial direction of the first branch pipe 100, the annular baffle 300 may be provided with reinforcing ribs 500 on both sides, both sides or only one side. It should be noted that when the clamping protrusion 400 is fixed outside the first branch pipe 100, the reinforcing ribs 500 cannot affect the normal use of the clamping protrusion 400.

[0035] In some preferred embodiments, in order to improve the reinforcing effect of the reinforcing rib 500, a reinforcing protrusion 600 is fixedly sleeved on the outer wall of the first branch pipe 100. The reinforcing protrusion 600 and the reinforcing rib 500 are located on the same side of the annular baffle 300, and compared with the reinforcing rib 500, the reinforcing protrusion 600 is farther away from the annular baffle 300, and is located on the side of the reinforcing rib 500 away from the annular protrusion, and is fixedly connected to the reinforcing rib 500. In the case where the reinforcing rib 500 is located on the side of the annular baffle 300 close to the clamping protrusion 400, the reinforcing protrusion 600 is also located on the same side; in the case where the reinforcing rib 500 is located on the side of the annular baffle 300 close to the second branch pipe 200, the reinforcing protrusion 600 is also located on the same side; if the reinforcing rib 500 is provided on both sides of the annular baffle 300, the reinforcing protrusion 600 is also provided on both sides of the annular baffle 300.

[0036] In the axial direction of the first branch pipe 100, the reinforcing rib 500 is fixed between the annular baffle 300 and the reinforcing protrusion 600, which can improve the supporting effect of the reinforcing rib 500 on the annular baffle 300, thereby further improving the strength of the annular baffle 300 and improving the stopping effect of the annular baffle 300. Further preferably, along the axial direction of the first branch pipe 100, the change trend of the size of the reinforcing protrusion 600 in the radial direction of the first branch pipe 100 is the same as the change trend of the size of the reinforcing rib 500 in the radial direction of the first branch pipe 100, refer to Figure 4 As shown, the rib 500 and the reinforcement protrusion 600 on the same side of the annular baffle 300 have the same size change trend, which is gradually increasing or decreasing. In addition, the outer surface of the reinforcement protrusion 600 is flush with the outer surface of the rib 500. Figure 4 The reinforcing protrusion 600 and the reinforcing rib 500 have a smooth transition, and there is no obvious protrusion or depression at the connecting position, which is conducive to improving the grip feel of the first branch pipe 100 and improving the comfort of the operator.

[0037] In some preferred embodiments, there may be multiple reinforcing ribs 500, and the multiple reinforcing ribs 500 are distributed along the circumference of the first branch pipe 100, and a receiving space for accommodating the operator's fingers is formed between two adjacent reinforcing ribs 500, which can be referred to Figures 1 to 3 On the one hand, the plurality of reinforcing ribs 500 can further enhance the structural strength and stability of the annular baffle 300 , and on the other hand, after the operator's fingers are placed in the accommodation space, they are less likely to slip, making it easier for the operator to control the position of the first branch pipe 100 .

[0038] When the pipe connector 10 is held and controlled, it can be held on the first branch pipe 100 on both sides of the annular baffle 300. In some embodiments of the present application, a plurality of anti-skid protrusions 700 can be provided on the outer wall of the first branch pipe 100, and the plurality of anti-skid protrusions 700 are all located on the side of the annular baffle 300 away from the liquid inlet of the first branch pipe 100, and the radial dimension of the anti-skid protrusion 700 is smaller than the radial dimension of the annular baffle 300, referring to Figures 1 to 4 The anti-skid protrusion 700 is used to increase the friction between the operator and the first branch pipe 100, and reduce the possibility of the operator slipping on the first branch pipe 100. The anti-skid protrusion 700 mainly plays an anti-skid role. The radial dimension of the anti-skid protrusion 700 is smaller than the radial dimension of the annular baffle 300 to avoid its excessive size affecting the stopping effect of the annular baffle 300.

[0039] In some preferred embodiments, the distance between the anti-skid protrusion 700 close to the annular baffle 300 and the annular baffle 300 is smaller than the distance between any adjacent anti-skid protrusions 700. By reducing the distance between the anti-skid protrusion 700 and the annular baffle 300, the impact force of the operator's finger on the annular baffle 300 after it is separated from the anti-skid protrusion 700 is reduced. In addition, when designing the anti-skid protrusion 700, at least two anti-skid protrusions 700 are generally provided to correspond to one finger to ensure that the anti-skid protrusion 700 can play a good anti-skid effect. Under such a layout, the size between the annular baffle 300 and the anti-skid protrusion 700 is small, which can ensure that the operator can hold on to at least one anti-skid protrusion 700 when the annular baffle 300 is stopped and limited, thereby enhancing the friction force and facilitating the application of force to the first branch pipe 100.

[0040] The embodiment of the present application further provides a cleaning assembly, comprising the pipe joint 10 provided in any of the above embodiments, and further comprising a cleaning pipe 20, wherein the second branch pipe 200 of the pipe joint 10 is connected to the cleaning pipe 20. The number of the cleaning pipes 20 is the same as the number of the second branch pipes 200, and the two are arranged one by one, refer to Figure 5 As shown, the connection diagram of the cleaning component and the endoscope handle 30 is shown in FIG. Figure 6 shown.

[0041] The embodiment of the present application also provides an endoscope cleaning and disinfecting device, including the cleaning assembly provided by any of the above embodiments, and also including a cleaning and disinfecting device. Among them, in the cleaning assembly, the first branch pipe 100 of the pipe connector 10 is connected to the cleaning and disinfecting device. Specifically, the first branch pipe 100 is connected to the cleaning nozzle.
