Description

Technical Field

[0001] This utility model belongs to the field of medical device disinfection technology, specifically relating to a medical supply room instrument disinfection device. Background Technology

[0002] In medical supply rooms, instrument sterilization devices are crucial for cleaning and sterilizing medical devices. Among existing technologies, the patent technology with publication number CN222153316U, entitled "An Anti-Pinch Flexible Endoscope Cleaning and Sterilization Machine," mainly comprises a cleaning chamber (4), an upper cover (1) located at the upper port of the cleaning chamber (4), and a drive mechanism for opening and closing the upper cover (1). A sealing ring (2) is also provided at the upper port of the cleaning chamber (4). The sealing ring (2) contains an upper or lower conductor that is subjected to pressure displacement. The upper and lower conductors are spaced apart, and the upper conductor and / or the lower conductor are led out from the electrical cavity (12) and connected to a controller. The controller is connected to the drive mechanism, and the drive mechanism is started and stopped via a conductor contact signal to achieve the anti-pinch function. The core function of this device is to prevent the flexible endoscope from being pinched and damaged by the upper cover when left at the cleaning chamber port through the conductive structure within the sealing ring, thus addressing the anti-pinch problem.

[0003] However, this existing technology has obvious shortcomings: its sealing ring (2) is located at the upper port (lower part) of the cleaning chamber (4). During the process of picking up and putting down instruments, liquid will still splash onto the port of the disinfection chamber, and the presence of the sealing ring (2) provides a basis for liquid accumulation. Long-term accumulation of liquid is prone to bacterial growth, affecting the disinfection effect, and failing to solve the problems of liquid residue and bacterial growth.

[0004] The methods described in this section are not necessarily methods that had been previously conceived or adopted. Unless otherwise specified, no method described in this section should be assumed to be prior art simply because it is included in this section. Similarly, unless otherwise specified, the issues mentioned in this section should not be considered to be accepted in any prior art. Utility Model Content

[0005] The purpose of this invention is to provide a medical supply room instrument disinfection device to solve the problem in the prior art where the sealing ring is placed at the port of the disinfection chamber, which leads to easy accumulation of liquid, growth of bacteria, and affects the disinfection effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A medical supply room instrument sterilization device includes a sterilization chamber, a cover disposed above the sterilization chamber for sealing the upper end of the sterilization chamber, and a drive structure for driving the cover to open and close. It also includes a sealing ring disposed below the cover for sealing the gap between the cover and the sterilization chamber. The sealing ring has an upper conductor and a lower conductor that are longitudinally spaced and opposite to each other inside. The upper conductor, the lower conductor and the drive structure are all electrically connected to a controller.

[0008] Furthermore, the upper conductor is coated with an upper conductive silicone.

[0009] Furthermore, the lower conductor is externally coated with a conductive silicone rubber.

[0010] Furthermore, the longitudinal cross-sectional shape of the sealing ring gradually tapers from top to bottom.

[0011] Furthermore, the lower end of the cover is provided with an annular groove, and the sealing ring has an annular locking element for engaging with the annular groove;

[0012] The annular card has grooves on both its inner and outer sides, and the annular card slot has protrusions on both its inner and outer sides corresponding to the grooves.

[0013] Furthermore, the sealing ring has a hollow deformation cavity, and a buffer airbag is connected to the side of the sealing ring, with the internal space of the buffer airbag communicating with the deformation cavity.

[0014] Furthermore, the buffer airbag has a built-in air pressure sensor, which is electrically connected to the controller, and the buffer airbag extends laterally into the sealing ring.

[0015] Furthermore, both the upper conductor and the lower conductor are annular shapes adapted to the shape of the sealing ring.

[0016] Furthermore, the rear end of the cover has a rearwardly extending connector, which is hinged to the bracket on which the disinfection chamber is installed. The drive structure is located on the bracket and is connected to the connector in a transmission manner to drive the connector to rotate up and down.

[0017] Furthermore, the driving structure is an electric push rod, one end of which is hinged to the bracket and the other end is hinged to the connector.

[0018] This utility model has the following beneficial effects:

[0019] By placing the sealing ring below the cover, the existing technology of placing the sealing ring at the bottom is changed. When liquid splashes onto the port of the disinfection chamber, the sealing ring is moved upward, eliminating the basis for liquid accumulation at the port of the disinfection chamber, thereby reducing bacterial growth and improving the disinfection effect.

[0020] The upper and lower conductors inside the sealing ring, in conjunction with the controller and drive structure, allow the upper and lower conductors to come into contact under pressure when there is an obstacle at the disinfection chamber port during the closing process of the cover. This causes the controller to stop the drive structure from operating, thus providing anti-pinch protection and continuing the anti-pinch function of existing technologies.

[0021] The addition of upper and lower conductive silicone enhances the conductivity of the upper and lower conductors, thereby improving the reliability of the detection.

[0022] The shape of the sealing ring, with its longitudinal section gradually tapering from top to bottom, helps the liquid slide off, further reducing liquid residue.

[0023] The snap-fit ​​structure of the annular groove and the annular clip, as well as the fit between the groove and the protrusion, makes the connection between the sealing ring and the cover more secure, and facilitates installation and disassembly.

[0024] The design connecting the buffer airbag and the deformation chamber can buffer the air pressure generated during sealing, reduce the squeezing force of the sealing ring on the instrument, and at the same time, the inwardly extending buffer airbag can prevent itself from being squeezed, and can also be used as a pull handle when removing the sealing ring, making it easy to remove.

[0025] The controller can determine the degree of compression of the sealing ring based on the air pressure changes within the buffer airbag, and combine this with the contact signals from the upper and lower conductors to form a dual detection mechanism. When the air pressure is abnormal or the conductors come into contact, the controller precisely controls the drive structure to stop operating, avoiding potential misjudgments that may occur when relying solely on conductor contact signals, and further improving the reliability of the anti-pinch protection.

Detailed Implementation

[0036] The present invention will be further described below with reference to the accompanying drawings.

[0037] Reference Figures 1-7 As shown, the medical supply room instrument disinfection device of this embodiment includes a disinfection chamber 1, a cover 2, a drive structure, and a sealing ring 3.

[0038] In this embodiment, the disinfection chamber 1 has a thin-walled structure with an outwardly extending edge 11 at its upper end. A cover 2 is positioned above the disinfection chamber 1 to seal its upper end. The rear end of the cover 2 has a rearwardly extending connector 22, which is hinged to the bracket on which the disinfection chamber 1 is mounted via a hinge shaft. The driving structure is an electric push rod, one end of which is hinged to the bracket, and the other end to the connector 22. When the piston rod of the electric push rod extends or retracts, it drives the connector 22 to rotate up and down, thereby causing the cover 2 to open and close.

[0039] In this embodiment, the lower end of the cover 2 is provided with an annular groove 21, and the sealing ring 3 has an annular retainer 33, which engages with the annular groove 21. Specifically, the annular retainer 33 has grooves 331 on both its inner and outer sides, and the annular groove 21 has corresponding protrusions 211 on both its inner and outer sides. The protrusions 211 are embedded in the grooves 331 to achieve a stable connection between the sealing ring 3 and the cover 2.

[0040] In this embodiment, the sealing ring 3 is located below the cover 2 to seal the gap between the cover 2 and the disinfection chamber 1. The longitudinal cross-sectional shape of the sealing ring 3 gradually tapers from top to bottom, which facilitates liquid sliding and reduces liquid accumulation on the sealing ring 3.

[0041] In this embodiment, the sealing ring 3 has a hollow deformation cavity 34 inside, and a buffer airbag 35 is connected to its side. The internal space of the buffer airbag 35 is in communication with the deformation cavity 34. The buffer airbag 35 extends laterally inside the sealing ring 3 and has a built-in air pressure sensor 351, which is electrically connected to the controller.

[0042] Meanwhile, the sealing ring 3 also has an upper conductor 31 and a lower conductor 32 arranged longitudinally and oppositely, both of which are annular and adapted to the shape of the sealing ring 3. The upper conductor 31 is covered with upper conductive silicone 311, and the lower conductor 32 is covered with lower conductive silicone 321. The upper conductor 31, the lower conductor 32, and the electric push rod are all electrically connected to the controller.

[0043] The working process is as follows: When medical devices need to be sterilized, the controller controls the piston rod of the electric push rod to retract, the cover 2 flips upward around the hinge axis, the upper end of the sterilization chamber 1 opens, and the device to be sterilized is placed into the sterilization chamber 1. Then, the controller controls the piston rod of the electric push rod to extend, the cover 2 flips downward, and gradually approaches the sterilization chamber 1.

[0044] During the closing process of the cover 2, the sealing ring 3 moves downward with the cover 2. When the sealing ring 3 abuts against the edge 11 at the upper end of the disinfection chamber 1, a seal is formed. If there are no obstructions at the port of the disinfection chamber 1, the sealing ring 3 is evenly compressed, and the upper conductor 31 and the lower conductor 32 remain spaced apart and do not contact each other. The controller controls the electric push rod to continue moving until the cover 2 is completely closed, achieving a seal on the disinfection chamber 1 for disinfection. At this time, because the sealing ring 3 is located below the cover 2, even if liquid splashes onto the port of the disinfection chamber, it cannot form an accumulation base at the port of the disinfection chamber due to the upward position of the sealing ring. The liquid can flow down along the edge 11 of the port of the disinfection chamber, reducing the possibility of bacterial growth.

[0045] If there are obstructions such as instruments at the port of the disinfection chamber 1, when the sealing ring 3 comes into contact with the obstruction, the obstruction will exert local pressure on the sealing ring 3, causing local deformation of the sealing ring 3, resulting in pressure contact between the upper conductor 31 and the lower conductor 32. At this time, the upper conductor 31 and the lower conductor 32 form an electrical connection, and the signal is transmitted to the controller. The controller controls the electric push rod to stop moving and can issue an alarm signal to prevent the cover 2 from continuing to close and damaging the instruments, thus achieving an anti-pinch function similar to existing technologies.

[0046] During the sealing process, the sealing ring 3 is compressed, causing changes in air pressure within the deformation chamber 34 and the buffer airbag 35. The air pressure sensor 351 monitors the air pressure within the buffer airbag 35 in real time and transmits the signal to the controller. Based on the air pressure signal, the controller can determine whether the sealing status is normal. Simultaneously, the buffer airbag 35 buffers the air pressure generated during sealing, reducing the compressive force of the sealing ring 3 on the instrument and protecting it. Notably, the controller 5 can determine the degree of compression of the sealing ring 3 based on air pressure changes, and combined with the contact signals from the upper conductor 31 and lower conductor 32, more precisely control the movement of the drive structure, further improving the reliability of the anti-pinch protection.

[0047] When it is necessary to remove the sealing ring 3 for cleaning or replacement, the buffer airbag 35 extending inward can be pulled to easily remove the sealing ring 3 from the cover 2, making the operation convenient.

[0048] In summary, by placing the sealing ring below the cover, this utility model solves the problem of liquid accumulating and bacteria growing at the port of the disinfection chamber in the prior art, while maintaining the anti-pinch function of the existing technology, thus improving the practicality and reliability of the disinfection device.

[0049] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
