DETAILED DESCRIPTION

[0034] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0035] The present invention provides an endoscope host. The endoscope host is used in conjunction with an endoscope and can set and control various parameters of the endoscope. The endoscope host is in a box-type structure. The box-type structure can facilitate the transportation and storage of the endoscope host.

[0036] See also Figure 1 and Figure 2 The endoscope host 10 of this embodiment includes a chassis 11, a base plate 12, a main control board 13, a pump group 14 and a gas-liquid conveying device 19.

[0037] The chassis 11 is used to accommodate the bottom plate 12, the main control board 13 and the pump unit 14. In addition, the chassis 11 includes a cover 111 and a box body 112. One side of the cover 111 and one side of the box body 112 can be flipped and connected. It can be understood that the chassis 11 can also be provided with a bandage or the like to fix the cover 111 and the box body 112 to prevent the cover 111 and the box body 112 from being separated and causing inconvenience. In addition, rollers (not shown) can be installed on the outside of the box body 112 to facilitate the quick movement of the chassis 11. In addition, a handle 15 can be provided on the outside of the box body 112 for convenient hand carrying.

[0038] In addition, anti-collision protective covers 16 are provided at the top corners of the chassis 11, and the protective covers 16 can improve the strength of the chassis 11 and prevent the chassis 11 from being damaged during transportation and movement.

[0039] When the endoscope needs to be used, the box cover 111 is opened. The box cover 111 is provided with a display device 113. The display device 113 can be used to display the working state and working parameters of the endoscope. In addition, it can be understood that the endoscope host can also include a camera assembly (not shown). The camera assembly can also be arranged on the box cover 111, and the purpose of convenient communication and remote control can be achieved through the camera assembly.

[0040] The box body 112 is provided with a cover 114. The cover 114 closes the box body 112, so that the box body 112 is in a closed state. In addition, an input device 115 is provided on the cover 114. The input device 115 can be a keyboard, a touch screen, etc. The endoscope host 10 can set various working parameters of the endoscope through the input device 115.

[0041] The bottom plate 12 is received at the bottom of the box 112. The shape of the bottom plate 12 matches the shape of the box 112 to ensure that the bottom plate 12 can be stably received in the box 112. Specifically in this embodiment, the box 112 is a cuboid, and the bottom plate 12 is a rectangle.

[0042] The bottom plate 12 may be a metal plate with a rubber layer on the outside. The bottom plate 12 has a relatively strong strength and is used to support various components in the box body 112. A plurality of mounting holes 121 are provided on the bottom plate 12 for mounting components such as the main control board 13 and the pump unit 14. The mounting holes 121 may be threaded through holes, through holes, or countersunk holes. The specific structure and type of the mounting holes 121 may be designed accordingly according to the installation requirements.

[0043] The main control board 13 is the main board of the endoscope host 10. The main control board 13 is disposed on the bottom plate 12, and the main control board 13 is disposed close to one end of the bottom plate 12.

[0044] Specifically in this embodiment, the endoscope host 10 further includes an anti-interference module 18. The anti-interference module 18 can be used to filter interference wave signals generated when each pump of the pump group 14 is working, so as to avoid affecting the control function of the processor.

[0045] Please also see Figure 3 The pump group 14 is connected to the main control board 13 by electrical signals, and the pump group 14 is arranged on the other side of the box body 112. The main control board 13 and the pump group 14 are arranged on both sides of the bottom plate 12 at intervals. The pump group 14 is located on the other side of the bottom plate 12 relative to the main control board 13 to increase the distance between the pump group 14 and the main control board 13, which can prevent the electromagnetic interference signal generated by the pump group 14 from interfering with the main control board 13.

[0046] Please refer again Figure 2 A heat dissipation hole 116 is provided on a side wall of the box body 112 near the pump unit 14 so as to dissipate the heat generated by the operation of the pump unit 14 in the box body 112 as soon as possible.

[0047] Specifically in this embodiment, the pump group 14 includes at least one pump. Specifically in this embodiment, the pump group 14 includes three pumps. The three pumps may include: an air-water pump 141 , an additional water pump 142 , and a suction pump 143 .

[0048] The air-water pump 141 can flush the surface of the endoscope lens entering the human body with air and liquid to prevent blood stains from blocking the lens and ensure that the lens captures clear images. In addition, the attached water pump 142 can flush the wound surface of the human body to ensure that the wound surface can present a clear actual situation. The suction pump 143 is used to suck out the blood and water in the human body.

[0049] The air-water pump 141 , the attached water pump 142 and the suction pump 143 are all electrically connected to the main control board 13 . The main control board 13 controls the operation of the air-water pump 141 , the attached water pump 142 and the suction pump 143 .

[0050] Please also see Figure 4 Specifically, the air-water pump 141, the attached water pump 142 and the suction pump 143 are all connected to the main control board 13 through the anti-interference module 18. The air-water pump 141, the attached water pump 142 and the suction pump 143 can avoid mutual interference between the signals of the air-water pump 141, the attached water pump 142 and the suction pump 143 through the anti-interference module 18, and the anti-interference module 18 can also prevent the air-water pump 141, the attached water pump 142 and the suction pump 143 from interfering with the main control board 13 and affecting the control work of other electrical modules on the main control board 13.

[0051] In addition, the air-water pump 141, the attached water pump 142 and the suction pump 143 are arranged in parallel on one side of the box 112. The multiple pumps in the pump group 14 are placed centrally to avoid the relative dispersion of the multiple pumps and the electromagnetic interference to the main control board 13, which is beneficial to the circuit layout of the main control board 13.

[0052] Please also see Figure 5 Specifically in this embodiment, the endoscope host 10 further includes a bracket 144. The bracket 144 is used to fix the pump group 14, and the bracket 144 is fixedly arranged on the bottom plate 12. Specifically in this embodiment, the bracket 144 is described by taking the example of being used to specify the attached water pump 142. Similarly, the bracket 144 can also be used to fix the air-water pump 141 and the suction pump 143, which will not be repeated here.

[0053] Specifically, the bracket 144 includes a frame body 145 and an isolation member 146 .

[0054] The frame 145 covers the outer side of the pump 140 . In addition, the frame 145 can be a plastic part. The frame 145 can buffer the vibration of the pump 140 .

[0055] The isolating member 146 may be an isolating cover. The isolating cover may be disposed on the outside of the frame 145. Furthermore, the isolating cover is a cover made of a rigid material and has a certain strength. The isolating member 146 may limit the vibration frequency and amplitude of the pump 140 through the buffer frame. Therefore, the isolating cover and the buffer frame may buffer the vibration energy of the pump 140, and prevent the vibration energy from being excessively transmitted to the bottom plate 12, thereby causing the vibration of the main control board 13 on the bottom plate 12.

[0056] The support leg 147 can be fixedly connected to the bottom plate 12. It can be understood that the support leg 147 of the frame 145 is fixedly connected to the bottom plate 12 by means of screws or the like. In addition, the isolation member 146 is disposed on the outside of the pump to isolate the magnetic signal generated by the pump 140. The isolation member 146 is disposed on the frame 145. There can be multiple isolation members 146, and multiple isolation members 146 can form a cover to better isolate the electromagnetic interference signal generated by the pump.

[0057] Please also see Figure 5 , and, specifically in this embodiment, a shock absorbing column 17 is further provided between the bracket 144 and the bottom plate 12. The shock absorbing column 17 is distributed around the pump 140. A mounting hole is provided at the bottom of the pump 140, and the shock absorbing column 17 passes through the mounting hole to achieve the connection between the pump 140 and the bottom plate 12. Since the shock absorbing column 17 is made of a flexible material, the shock absorbing column 17 can buffer and reduce the vibration energy between the pump 140 and the bottom plate 12. The shock absorbing column 17 can be integrally formed, or integrally injection molded.

[0058] The shock absorbing column 17 can space the pump 140 from the bottom plate 12 to avoid direct contact between the suction pump 143 and the bottom plate 12. If the bottom plate 12 is affected by the vibration energy for a long time, the electronic components installed on the bottom plate 12 will inevitably be damaged, affecting the service life of the endoscope host 10.

[0059] When the pump 140 is working, the pump 140 will vibrate, and the vibration energy at the bottom of the pump 140 can be buffered by the shock-absorbing column 17 and then transferred to the bottom plate 12. The vibration energy outside the pump 140 can be buffered by the buffer frame and the isolation cover and then transferred to the bottom plate 12. The endoscope host 10 of this embodiment can alleviate the influence of the pump 140 on the stability of the bottom plate 12 when it is in the working state through the shock-absorbing column 17, reduce the vibration energy transmitted to the bottom plate 12 by the pump 140, thereby ensuring the stability of the connection of various electronic components on the bottom plate 12 and ensuring the service life of the endoscope host 10.

[0060] Specifically in this embodiment, the shock-absorbing column 17 includes a lower connecting portion 171, a connecting column 172 and an upper connecting portion 173 arranged in sequence from bottom to top. The lower connecting portion 171 is connected to the bottom plate 12, the upper connecting portion 173 is connected to the bracket 144 at a right angle, and the connecting column 172 is pressed between the bottom plate 12 and the support leg 147 of the bracket 144. When the pump 140 is started, the motor generates vibration energy. The vibration energy transfers the bracket 144 to the shock-absorbing column 17. The connecting column 172 blocks the vibration energy to prevent the vibration energy from being directly transmitted to the bottom plate 12, thereby protecting the components on the bottom plate 12. At the same time, the noise generated by the pump 140 during operation can be eliminated, thereby reducing the impact of the built-in pump group 14 on the endoscope host 10.

[0061] Specifically, the lower connecting portion 171 is a cone, and the upper connecting portion 173 is also a cone. The cone of the lower connecting portion 171 is snap-fitted with the mounting hole 121 of the bottom plate 12. The cone of the upper connecting portion 173 is snap-fitted with the mounting hole of the support leg 147. The conical surface of the cone can be easily snapped into the mounting holes of the bottom plate 12 and the support leg 147, and the operation is convenient.

[0062] Specifically in this embodiment, there are multiple shock-absorbing columns 17. Multiple shock-absorbing columns 17 are evenly distributed around the pump. Specifically in this embodiment, there are four shock-absorbing columns 17. Four shock-absorbing columns 17 can be set at positions where the weight of the pump is more distributed, which can minimize the transmission of vibration to the bottom plate 12.

[0063] It is understandable that the number of the shock absorbing columns 17 can also be 3, 5, etc., and can be designed accordingly according to specific design requirements.

[0064] Please also see Figure 6 and Figure 7 The gas-liquid conveying device 19 is arranged outside the box body 112. The gas-liquid conveying device 19 is connected and conducted through a connecting valve, and the gas-liquid conveying device 19 is detachably connected to the chassis.

[0065] The gas-liquid conveying device 19 includes a bottle body. The bottle body can be a transparent bottle, a glass bottle or a plastic bottle. The transparent bottle can be convenient for observing the liquid level in the bottle body. There can be multiple bottles. One bottle body corresponds to one pump in the pump group.

[0066] The bottle mouth of each bottle body is provided with a sealing plug 191. A plurality of outlets may be provided on the sealing plug 191. According to the different use functions of the bottle body, each outlet may be selectively connected to the gas path and the liquid path of the endoscope.

[0067] A connecting valve 192 for communicating with a pump is provided at the bottom of the bottle.

[0068] A through hole 117 is provided on the side wall of the box 112. The connecting valve 192 is sealedly connected to the pump inside the box through the through hole 117 to ensure air tightness during the operation of the pump. The connecting valve 192 is a sealed connecting valve. Figure 8 Specifically, in this embodiment, the connecting valve 192 includes an adapter seat 1920, an air inlet pipe 1921 and an air outlet pipe 1922. The air inlet pipe 1921 is connected to the air outlet pipe 1922 through the adapter seat 1920. The adapter seat 1920 is cylindrical. The air inlet pipe 1921 is located outside the bottle body. The air outlet pipe 1922 is located inside the bottle body. The air inlet pipe 1921 extends toward the box body, and the air outlet pipe 1922 extends along the axial direction of the bottle body. The air inlet pipe 1921 can be directly inserted into the through hole 117. The air outlet pipe 1922 ensures that the gas can be discharged smoothly. Specifically, the air inlet pipe 1921 is perpendicular to the air outlet pipe 1922.

[0069] See also Fig. 9 Specifically in this embodiment, an airtight joint 119 may also be provided in the through hole 117. The airtight joint 119 is located at one end inside the box body for airtight connection with the pump group 14, and is located at one end outside the box body 112 for airtight connection with the air inlet pipe 1921.

[0070] According to different functions, the bottle body may include a gas water bottle 194 and a water storage bottle 195. Specifically, in this embodiment, the gas water bottle 194 is placed in front of the water storage bottle 195. In other embodiments, the gas water bottle 194 may also be placed behind the water storage bottle 195. The placement position of the gas water bottle 194 and the water storage bottle 195 is not limited here.

[0071] The gas-water bottle 194 is connected to the gas-water pump 141. The two outlets of the gas-water bottle 194 are respectively connected to the air inlet pipeline and the liquid inlet pipeline of the endoscope. The water storage bottle 195 is connected to the attached water pump 142. One outlet of the water storage bottle 195 is connected to the liquid inlet pipeline of the endoscope, and the other outlet is in a sealed state as a backup interface. The attached water pump 142 delivers clean water to the endoscope through the water storage bottle 195. It can be understood that the water storage bottle 195 can be provided with an outlet, and the backup interface can be omitted.

[0072] When the air-water pump 141 and the attached water pump 142 are started, they pressurize the bottle body respectively, so that a pressure difference is generated between the bottle body and the outside, thereby pressing pure water or disinfectant gas into the human body to achieve the purpose of flushing the wound surface and the endoscope lens.

[0073] Please refer again Figure 6 The gas-liquid conveying device 19 also includes a dirty water bottle 196. The dirty water bottle 196 is connected to the suction pump 143. A sealing plug is provided at the bottle mouth of the dirty water bottle 196, and the sealing plug is provided with an inlet and an outlet. The inlet is used to communicate with the suction pump 143, and the outlet is used to communicate with the suction tube of the endoscope. The suction pump 143 can be a vacuum pump and is connected to the dirty water bottle 196. After starting, the dirty water bottle 196 is evacuated, and a negative pressure is formed in the dirty water bottle 196, thereby forming a pressure difference between the dirty water bottle 196 and the human body cavity, so that the waste liquid is extracted into the dirty water bottle 196.

[0074] Specifically in this embodiment, the dirty water bottle 196 is arranged opposite to the gas water bottle 194 and the water storage bottle 195. The dirty water bottle 196 can be arranged on the other side of the box body 112. Then the other side of the box body 112 is also provided with a through hole 118. The through hole 118 is used to connect with the dirty water bottle 196.

[0075] See also Fig. 9 and Fig.10Specifically in this embodiment, the gas-liquid delivery device 19 also includes a fixing member 193. The bottle body can be fixedly provided on the fixing member 193. The fixing member 193 includes two hinged fixing plates. Among them, the first fixing plate 1931 is used to achieve a detachable connection with the box body 112. The first fixing plate 1931 is provided with a snap-fit ​​structure 1934. The snap-fit ​​structure 1934 is used to snap-fit ​​and connect with the box body 112. It can be understood that the snap-fit ​​structure 1934 can be a hook, a slot or a buckle, etc. Figure 8 As shown, a matching snap-fit ​​structure 1121 is correspondingly provided on the box body 112 .

[0076] The second fixing plate 1932 is used to fix the bottle body. The second fixing plate 1932 is provided with a receiving groove 1933 adapted to the bottom of the bottle body, and the connecting valve 192 located at the bottom of the bottle body can be fixedly received in the receiving groove 1933 .

[0077] See also Fig.10 Specifically, in this embodiment, the receiving groove 1933 includes an opening section 1935 and a receiving section 1936. The opening section 1935 is disposed on one side of the receiving section 1936 and is in communication with each other. The connecting valve 192 enters from the opening section 1935, moves along the opening section 1935 to the receiving section 1936, and is positioned with the receiving section 1936.

[0078] The opening section 1935 is a through slot that passes through one side of the second fixing plate 1932 .

[0079] The receiving section 1936 is adapted to the shape of the connecting valve 192. The receiving section 1936 is a circular through hole. The adapter seat 1920 of the connecting valve 192 is provided with a card slot 1923. The card slot 1923 is provided around the annular periphery of the adapter seat 1920. The adapter seat 1920 is made of an elastic material. The size of the adapter seat 1920 at the card slot 1923 is slightly larger than the size of the opening section 1935. When the connecting valve 192 is assembled, the corresponding part of the card slot 1923 of the adapter seat 1920 is compressed and contracted, and is inserted into the receiving slot 1933 along the opening section 1935.

[0080] When the adapter 1920 is inserted and moved to the receiving section 1936. Since the receiving section 1936 is circular and its aperture is larger than the aperture of the opening section 1935, the adapter 1920 recovers its deformation at the receiving section 1936 and is fixed in the receiving section 1936. In addition, the clamping groove 1923 is a non-closed annular groove. The adapter 1920 is provided with a limiting portion 1925 adapted to the opening section 1935 at one end of the clamping groove 1923 away from the air inlet pipe 1921. The limiting portion 1925 is accommodated in the opening section 1935 to prevent the adapter 1920 from rotating. Thus, the bottle body is fixedly mounted on the second fixing plate 1932. When the bottle body needs to be removed from the second fixing plate 1932 , the adapter 1920 is first shrunk along the opening section 1935 and moved out of the receiving groove 193 , thereby completing the separation of the bottle body and the second fixing plate 1932 .

[0081] Please also see Figure 8 and Fig. 9 When the gas-liquid delivery device 19 is needed, the fixing member 193 is opened. The fixing member 193 is fixed to the box 112 by engaging the first fixing plate 1931 with the outer wall of the box 111. When the host is not in use, the fixing member 193 can be removed from the box 112 for easy transportation and storage. In addition, each bottle body is installed on the second fixing plate 1932, and the connecting valve 192 at the bottom of the bottle body can be engaged in the receiving groove 1933 of the second fixing plate 1932 to fix the bottle body.

[0082] Specifically in this embodiment, specifically in this embodiment, the host further includes a disinfection box (not shown). The disinfection box is connected to the air-water pump 141. The disinfection box can disinfect and sterilize the gas pumped into the human body by the air-water pump 141 to prevent bacteria and viruses from entering the human body with the gas, causing the risk of virus infection.

[0083] See also Figure 4 Specifically in this embodiment, an image processing module 131 may be further provided on the main control board 13. The anti-interference module 18 can prevent interference signals generated by the air-water pump 141, the attached water pump 142 and the suction pump 143 from affecting the image processing module 131 and the image quality of the image processing module 131.

[0084] The main control board 13 can realize parameter setting input of the air-water pump 141, the attached water pump 142 and the suction pump 143, and feedback display of the working status, etc. through the input device 115 and the display device 113. Therefore, the endoscope host 10 can realize centralized control of the air-water pump 141, the attached water pump 142 and the suction pump 143, avoiding the setting of multiple independent control hosts, which is not only complicated in structure and cumbersome in operation, but also not conducive to the safe use of the endoscope.

[0085] The pump group 14 is integrated into the case 111. When a medical facility is temporarily built outdoors, the connection can be achieved by simply connecting the sewage box and the gas cylinder to the first through hole 117 and the second through hole 118 on the case 112. Moreover, there is no need to provide various external support devices for each pump 140 in the pump group 14, which facilitates the use of the endoscope host 10.

[0086] Furthermore, each pump in the pump group 14 of the endoscope host 10 is electrically connected to the main control board 13, and the pump group 14 can be controlled and parameterized through the endoscope host, which is easy to operate.
