Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment drying devices, in particular to a desktop endoscope drying device. Background Art

[0002] The medical endoscope is a minimally invasive medical device used to diagnose and treat a variety of diseases. It is mainly composed of a front-end device, a transmission system and a workstation. The front-end device includes a lens, an optical rod and an operating tool for observation or resection, sampling and other operations. The transmission system consists of a series of pipes and connectors, which are responsible for inserting the front-end device into the body and transmitting images and data. The workstation is the control center of the endoscope, responsible for controlling the operation of the device and displaying images. Doctors can operate the endoscope through the workstation.

[0003] Medical endoscopes can be divided into two types: flexible endoscopes and rigid endoscopes. Flexible endoscopes are soft tubes that can enter the body through natural orifices or small surgical incisions to observe diseased tissues and perform treatment operations. Endoscopes need to be disinfected after each operation. Currently, there are two main ways to clean and disinfect medical flexible endoscopes: one is to use a cleaning workstation for manual cleaning and disinfection; the other is to use an endoscope cleaning and disinfection machine, which automatically completes the cleaning and disinfection. After disinfection, the inner cavity of the endoscope's pipeline also needs to be dried to remove the disinfectant and moisture remaining in the inner cavity of the endoscope's pipeline. The residual moisture can easily provide a growth environment for the growth of bacteria. If the drying is not thorough, it will cause endoscope contamination, causing infection incidents when used in subsequent surgeries.

[0004] Endoscopes are usually dried using dedicated drying equipment, such as the prior art "An Endoscope Storage Drying Equipment" (Publication No.: CN209253129U), which dries the inner cavity of the endoscope by hanging the endoscope inside a cabinet and sucking out the residual water in the inner cavity of the endoscope through a water suction pump. However, the prior art still has the following technical problems:

[0005] 1. The drying equipment of the prior art needs to hang multiple endoscopes, which need to be connected to the suction device after hanging, and the operation steps are complicated; at the same time, the hung endoscopes will take up a large space, resulting in a larger volume structure of the cabinet. When it needs to be moved to different locations for use, it is inconvenient to move and place, and the portability is poor.

[0006] 2. The drying equipment in the prior art cannot accurately limit the drying time. If the drying time is too long, the equipment will work for a long time and cause energy waste. If the drying time is too short, the inner cavity of the endoscope will not be completely dried, and bacteria will remain in the inner cavity of the endoscope, causing infection to the patient during subsequent use. Utility Model Content

[0007] In view of the shortcomings of existing endoscope drying devices, the utility model provides a desktop endoscope drying device, which can solve the problem that the endoscope drying device in the prior art has a large volume and structure, is inconvenient to move and place, and leads to poor portability.

[0008] The present application provides the following technical solutions: a desktop endoscope drying device, comprising a housing, a power supply fixed in the housing, and a plurality of negative pressure suction devices fixed in the housing;

[0009] The housing comprises a lower cover, a front panel and a rear panel respectively fixed on both sides of the lower cover;

[0010] Two L-shaped positioning plates arranged back to back are fixed on the lower cover, the negative pressure suction devices are fixed on the positioning plates, and the negative pressure suction devices are arranged back to back; the power supply is located on one side of the negative pressure suction device;

[0012] A power socket and a cooling fan are fixed on the rear panel, the power supply is electrically connected to the power socket, the cooling fan is opposite to the negative pressure suction device, and the power socket is located on one side of the cooling fan.

[0013] Beneficial effects:

[0014] 1. The two positioning plates are arranged back to back, so that the negative pressure suction device on the positioning plate can avoid interference from the front panel and the rear panel when installing or removing the connecting parts, and the connecting parts can be disassembled and assembled from between the two positioning plates, which improves the convenience of disassembly and assembly;

[0015] 2. The negative pressure suction device is set back to back, which can avoid the space between the two positioning plates being occupied by the pipe when installing the suction air pipe, which is conducive to placing the disassembly tool between the two positioning plates, thereby improving the convenience of disassembly and assembly operations;

[0016] 3. The endoscope connecting tube and the negative pressure suction device are located opposite to each other, which can shorten the distance of the connecting pipe between the endoscope connecting tube and the negative pressure suction device, thereby saving materials and reducing costs;

[0017] 4. The timing device is used to set the working time of the negative pressure suction device, so as to accurately control the drying time of the equipment and reduce power consumption;

[0018] 5. The cooling fan is opposite to the negative pressure suction device, so as to quickly discharge the heat generated by the cooling fan when it is working, reduce the internal temperature of the equipment, and avoid damage to internal parts;

[0019] 6. The equipment reasonably arranges the installation positions of various components and makes full use of the space inside the shell, so that the equipment has a more compact and small structure, which is convenient for transportation and placement, and improves the convenience of use.

[0020] Furthermore, the shell also includes an upper cover fixed on the lower cover, and the upper cover is an inverted U-shape.

[0021] Beneficial effects: The lower cover can be used as a positioning base for the internal devices of the equipment. After the upper cover, front panel and rear panel are fixed to the lower cover, the entire shell forms a complete rectangular shape, which wraps the parts of the equipment inside the shell and protects the internal parts. At the same time, after the upper cover is removed, the internal components of the equipment can be directly observed, which is conducive to the maintenance of the equipment parts.

[0022] Furthermore, a foot pad is fixed to the bottom surface of the lower cover.

[0023] Beneficial effect: Since the outer shell of the negative pressure suction device will shake when it is working, the foot pad can keep the outer shell of the device level and improve the stability of the device when it is working.

[0024] Furthermore, the negative pressure suction device includes a micro vacuum pump fixed on the positioning plate and a hose connected to the suction port of the micro vacuum pump, and the exhaust port of the micro vacuum pump is connected to a drain pipe.

[0025] Beneficial effects: The micro vacuum pump can generate negative pressure, thereby sucking away the residual moisture in the inner cavity of the endoscope, accelerating the evaporation of moisture in the inner cavity of the endoscope, and achieving the purpose of drying.

[0026] Furthermore, a drainage pipe joint is fixed on the rear panel, the drainage pipe is connected to the drainage pipe joint, and the drainage pipe joint is located between the cooling fan and the power plug.

[0027] Beneficial effect: the drainage pipe joint can be connected to an external drainage system, so that the micro vacuum pump can suck out the residual water in the inner cavity of the endoscope and send it into the drainage system through the drainage pipe.

[0028] Further, the timing device comprises a mounting shell fixed on the outer shell, the center of the mounting shell is rotatably connected to a rotating shaft, a cam is fixed on the rotating shaft, and an end of the rotating shaft away from the mounting shell is key-connected to a knob; a T-block is fixed at the bottom of the mounting shell, and an elastic circular arc piece is fixed at the end of the T-block;

[0029] The bottom of the mounting shell is also circumferentially evenly provided with a plurality of delay mechanisms, the delay mechanism comprising a first limit plate and a second limit plate fixed to the bottom of the mounting shell, a button switch being fixed to the first limit plate, a sliding rod being slidably connected to the second limit plate, a contact block being fixed to one end of the sliding rod away from the second limit plate, a compression spring being sleeved on the rod portion of the sliding rod between the contact block and the second limit plate, and two ends of the compression spring being respectively fixed to the second limit plate and the contact block; an arc groove is provided at one end of the contact block away from the sliding rod, and the cam can be stuck in the arc groove;

[0030] The timing device also includes a controller, and the controller, the button switch and the negative pressure suction device are electrically connected.

[0031] Beneficial effects:

[0032] 1. By rotating the knob, the cam is inserted into the arc groove at the end of the contact block, and the slide bar presses the button switch. After receiving the signal, the controller can control the circuit power-on time of the negative pressure suction device as needed, so as to control the negative pressure suction device to start and stop after a specific time, so as to achieve precise control of the equipment's drying time for the endoscope, avoid energy waste of the equipment due to inappropriate drying time, or cause surgical infection to the patient during subsequent use due to incomplete drying of the endoscope.

[0033] 2. After the drying time is over, rotate the knob to make the cam fit into the elastic arc piece, the knob is at zero position, and the negative pressure suction device does not work. At this time, the elastic arc piece can limit the cam. When the equipment is not working, it can prevent the knob from being turned due to external force, causing the button switch to be accidentally connected, resulting in abnormal startup of the equipment and energy waste.
