Description

Technical Field

[0001] The invention discloses an anti-pinching flexible endoscope cleaning and disinfecting machine, belonging to the technical field of medical equipment. Background Art

[0002] Electronic endoscopes are divided into flexible endoscopes and rigid endoscopes. Among them, flexible endoscopes mainly use the natural cavities of the human body to complete the inspection, diagnosis and treatment of diseased tissues inside the human body. They have the advantages of high image clarity and low pain for patients. Due to the precise structure and high cost of flexible endoscopes, flexible endoscopes need to be reused. Therefore, they need to be cleaned and disinfected by a cleaning and disinfection machine after each use.

[0003] The cleaning and disinfection machine for flexible endoscopes includes a cleaning chamber. During cleaning, the flexible endoscope to be cleaned is placed in the cleaning chamber, and then the cover at the port of the cleaning chamber is closed for cleaning. Since the flexible endoscope itself has a certain elasticity, when the flexible endoscope is placed in the cleaning chamber, it is easy for the flexible endoscope to be deformed due to the release of its own elastic force, and at this time, the flexible endoscope is easy to move to the port of the cleaning chamber.

[0004] Since current cleaning and disinfection machines generally have an automatic opening and closing function for the cleaning chamber, if a flexible endoscope is left at the port of the cleaning chamber as an obstacle, the remaining flexible endoscope will be squeezed when the cover of the cleaning chamber is closed, thereby damaging the flexible endoscope or the driving mechanism of the cover. Therefore, designing a technical solution with an anti-pinch function to avoid damage caused by the flexible endoscope remaining as an obstacle has become a problem that needs to be urgently solved in this field. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and to provide an anti-pinch flexible endoscope cleaning and disinfecting machine, in which an upper conductor and a lower conductor are arranged in a sealing ring at an upper port of a cleaning chamber, so that the upper conductor and / or the lower conductor are displaced and contacted during the closing process of the upper cover, thereby avoiding damage to the upper cover or the flexible endoscope due to the flexible endoscope being left at the upper port of the cleaning chamber as an obstacle.

[0006] The utility model adopts the following technical solution to solve the technical problem: the anti-pinch soft endoscope cleaning and disinfecting machine comprises a cleaning chamber, an upper cover is arranged at the upper port of the cleaning chamber, and a driving mechanism for driving the upper cover to open and close is arranged, a sealing ring is arranged at the upper port of the cleaning chamber, and the utility model is characterized in that an upper conductor or a lower conductor which is displaced by pressure is arranged inside the sealing ring, the upper conductor and the lower conductor are arranged at intervals, the upper conductor and / or the lower conductor are connected to a controller after being led out from the electrical cavity, and the controller is connected to the driving mechanism.

[0007] Preferably, a hollow electrical cavity is provided inside the sealing ring, and the upper conductor and the lower conductor are arranged in the electrical cavity at intervals.

[0008] Preferably, the upper conductor and the lower conductor include an upper conductive wire and a lower conductive wire, respectively.

[0009] Preferably, the outer portion of the upper conductive wire is coated with upper conductive silicone.

[0010] Preferably, the outer portion of the lower conductive wire is coated with lower conductive silicone.

[0011] Preferably, an annular clamping platform is protrudingly provided at the upper port of the cleaning chamber, and a sealing ring is clamped on the clamping platform.

[0012] Preferably, a lower end opening is provided below the sealing ring, which is used for a card slot to be connected with the card platform.

[0013] Preferably, a hollow deformation cavity is provided on the outer side of the card slot.

[0014] Preferably, the driving mechanism is an electric push rod, and the piston rod of the electric push rod is hinged to the upper cover.

[0015] Compared with the prior art, the utility model has the following beneficial effects: in the anti-pinch flexible endoscope cleaning and disinfecting machine, by arranging the upper conductor and the lower conductor in the sealing ring of the upper port of the cleaning chamber, the upper conductor and / or the lower conductor will be displaced and contacted during the closing process of the upper cover, thereby avoiding damage to the upper cover or the flexible endoscope due to the flexible endoscope being left as an obstacle at the upper port of the cleaning chamber.

[0016] In the anti-pinch soft endoscope cleaning and disinfecting machine, the upper conductive silicone and the lower conductive silicone are respectively coated on the outside of the upper conductive wire and the lower conductive wire, so as to increase the conductive effect.

[0017] In the anti-pinch flexible endoscope cleaning and disinfecting machine, a deformation cavity is also provided on the outer side of the card slot, so that a certain deformation margin is reserved when the card slot is connected with the card platform, thereby avoiding deformation of the sealing ring during installation, and at the same time providing a certain extrusion force to the card slot, so that the card slot and the card platform are reliably connected.

DETAILED DESCRIPTION

[0022] Figures 1 to 3 It is the best embodiment of the utility model, and the following Figures 1 to 3 The utility model is further described.

[0023] like Figure 1~2 As shown, an anti-pinch flexible endoscope cleaning and disinfecting machine includes a cleaning chamber 4 with an opening at the upper end. An openable and closable upper cover 1 is provided at the upper opening of the cleaning chamber 4 .

[0024] The rear end of the upper cover 1 is provided with a hinge block 6, and an electric push rod 8 is provided directly below the hinge block 6. The electric push rod 8 is implemented by a common product available in the market in this field, and will not be described in detail here. The top of the piston rod of the electric push rod 8 is hinged to the hinge block 6 through the rear pin 7. A front pin 5 is provided on the front side of the hinge block 6, and the rear side of the upper cover 1 is hinged to the front pin 5. When the electric push rod 8 is in motion, the upper cover 1 is opened and closed through the front pin 5 and the rear pin 7.

[0025] An annular clamping platform 3 is protrudingly provided around the upper opening of the cleaning chamber 4, and a sealing ring 2 is clamped on the surface of the clamping platform 3. When the upper cover 1 is closed under the action of the electric push rod 8, the outer periphery of the upper cover 1 contacts the periphery of the sealing ring 2 to seal the cleaning chamber 4.

[0026] like Figure 3 As shown, the sealing ring 2 is made of elastic material (such as rubber or silicone), and a ring-shaped electrical cavity 12 is provided in the middle of the sealing ring 4. An upper conductor and a lower conductor are provided in the electrical cavity 12. When the sealing ring 2 is not subjected to external force, the upper conductor and the lower conductor are provided at intervals. The position of the inner ring of the sealing ring 2 corresponding to the electrical cavity 12 is the extrusion portion 9 of the sealing ring 2. When the upper cover 1 is closed, the outer periphery of the upper cover 1 fits the extrusion portion 9.

[0027] The upper conductor includes an upper conductive silicone 11 and a lower conductive silicone 13 which are arranged relatively in the electrical cavity 12, an upper wire 10 is arranged in the upper conductive silicone 11, and a lower wire 14 is arranged in the lower conductive silicone 13. After the upper wire 10 and / or the lower wire 14 extend to the outside of the sealing ring 2, they are connected to the signal input end of an external controller (not shown in the figure), and the signal output end of the controller is connected to the input end of the electric push rod 8 to realize the control of the electric push rod 8.

[0028] When the upper wire 10 and the lower wire 14 are in contact, the state of the electrical signal output by the upper wire 10 or / and the lower wire 14 changes, such as the voltage signal output by the upper wire 10 or / and the lower wire 14 changes; or the current signal of the upper wire 10 or / and the lower wire 14 changes; the resistance signal of the upper wire 10 or / and the lower wire 14 changes, and the controller controls the electric push rod 8 to stop moving. By coating the upper conductive silicone 11 and the lower conductive silicone 13 on the outside of the upper wire 10 and the lower wire 14, respectively, the conductive effect is increased.

[0029] A clamping groove 16 with an opening at the lower end is provided in the inner ring at the lower part of the electrical cavity 12. When the sealing ring 2 is installed at the upper end of the cleaning chamber 4, it is clamped and connected with the clamping platform 3 at the upper end of the cleaning chamber 4 through the clamping groove 16. A deformation cavity 15 is also provided on the outer side of the clamping groove 16, so that a certain deformation margin is reserved when the clamping groove 16 is clamped with the clamping platform 3 to prevent the sealing ring 2 from deforming during installation, and at the same time, a certain extrusion force is provided to the clamping groove 16 so that the clamping groove 16 and the clamping platform 3 are reliably connected.

[0030] The specific working process and working principle are as follows: when the controller controls the piston rod of the electric push rod 8 to reset, the upper cover 1, under the joint action of the front pin shaft 5 and the rear pin shaft 7, makes the upper port of the cleaning chamber 4 in an open state. At this time, the flexible endoscope to be cleaned can be placed in the cleaning chamber 4, or the cleaned flexible endoscope can be taken out of the cleaning chamber 4.

[0031] When it is necessary to clean the flexible endoscope in the cleaning chamber 4, the controller controls the piston rod output of the electric push rod 8. At this time, the upper cover 1 is gradually closed under the joint action of the front pin shaft 5 and the rear pin shaft 7. When the circumference of the upper cover 1 fits with the extrusion part 9 of the sealing ring 2, the sealing of the cleaning chamber 4 is achieved.

[0032] When there is no obstacle at the port of the cleaning cabin 4 (such as a leaking flexible endoscope), after the upper cover 1 is closed, the pressure of the upper cover 1 is evenly applied to the extrusion portion 9 of the sealing ring 2. Since the extrusion portion 9 is evenly stressed at this time, the degree of deformation of the extrusion portion 9 is small, and it is not enough to make the upper conductor and the lower conductor in the electrical cavity 12 contact. If there is an obstacle at the port of the cleaning cabin 4, after the upper cover 1 is closed, the pressure of the upper cover 1 will first squeeze the obstacle, and further squeeze a certain point of the extrusion portion 9 through the obstacle. Therefore, the pressure of the obstacle acting on the extrusion portion 9 will be much greater than the pressure when the upper cover 1 evenly squeezes the sealing ring 2. At this time, in the electrical cavity 12, the upper conductor and the lower conductor will come into contact,

[0033] The force is evenly applied to the extrusion part 9 of the sealing ring 2. Since the extrusion part 9 is evenly stressed at this time, the deformation of the extrusion part 9 is small and insufficient to make the upper conductor and the lower conductor in the electrical cavity 12 contact. When the upper conductor and the lower conductor contact, the state of the electrical signal output by the upper wire 10 and / or the lower wire 14 changes. At this time, the controller controls the electric push rod 8 to stop moving and can sound an alarm to avoid the situation where the flexible endoscope is not placed in the cleaning chamber 4 as a whole, thereby achieving an anti-pinch effect.

[0034] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
