Description

Technical Field

[0001] The utility model relates to the technical field of medical instrument cleaning equipment, in particular to a surgical instrument pretreatment device. Background Art

[0002] Cleaning, disinfection and sterilization of medical devices are one of the key means to prevent and control hospital-acquired infections and ensure the quality of medical care. The treatment procedures for contaminated medical devices should be cleaning, disinfection, drying and sterilization, which is more conducive to reducing occupational infections in hospitals for medical staff and protecting the environment from pollution. However, surgical instruments will be stained with blood and dirt during use. If they are not cleaned in time, it is easy to cause the blood stains on the surgical instruments to coagulate and dry up. The dried blood stains will corrode the instruments and make them difficult to clean. Even the formation of biofilm will increase the difficulty of cleaning. Therefore, the instruments need to be pretreated immediately after use. The main purpose is to clean the blood stains on the surface of the instruments to avoid affecting the efficiency of subsequent treatment after long-term placement. In addition, strong scrubbing can easily cause mechanical damage. Traditional pretreatment methods mainly include wet gauze wiping, manual washing under running water, wet towel covering, moisturizer spraying, and sinking tank method. The uncertainty factors in traditional pretreatment methods will prolong the contact time between organic pollutants and instruments, which is easy to cause secondary pollution and is not conducive to the maintenance of instruments. In addition, manual cleaning is inefficient, time-consuming, and the standards are not uniform.

[0003] The Chinese utility model patent with announcement number CN215031577U discloses a surgical instrument pretreatment device, including a box, a box door, a sliding rod arranged at the top of the box, a hanging rod slidably connected to the sliding rod, a hook arranged at one end of the hanging rod away from the sliding rod, a U-shaped rod hung on the hook, and a cleaning device; by hanging the surgical instrument on the U-shaped rod, and then hanging the U-shaped rod on the hook and the side wall of the box, the cleaning device can be used to clean the surgical instrument in the box, and according to the number of surgical instruments, a U-shaped rod of appropriate length is selected, and since the hanging rod is slidable, U-shaped rods of various lengths can be stably fixed inside the box, so that the surgical instruments can be closely arranged on the U-shaped rod, so that there will be no large shaking during flushing. However, there are differences in the shapes of different surgical instruments. Due to the single hanging method of the U-shaped rod, the flushing effect for luminal surgical instruments is poor, and it is impossible to flexibly clean the surgical instruments added in the middle.

One end of the rubber connecting piece 542 matches the shape and size of the gourd-shaped liquid outlet 541. The other end of the rubber connecting piece 542 is connected to the main control electromagnetic valve 56 through a water pipe. The rubber connecting piece 542 is fixedly installed on the cabinet 1. When the liquid storage tank 54 is pushed into the cabinet 1, the gourd-shaped liquid outlet 541 and the rubber connecting piece 542 are interlocked and connected, which can play a role in sealing and preventing leakage. In addition, the liquid storage tank 54 is made of acrylic material and has good transparency. The user can directly observe the liquid level in the liquid storage tank 54, which is convenient for adding moisturizing liquid in time.

[0050] like Fig.10 As shown, the control system 6 in this embodiment is electrically connected to the water pump 55, the main control solenoid valve 56, the branch solenoid valve 57, the servo motor 5111 and the spring switch 4, respectively. The spring switch 4 of each layer is electrically connected to the branch solenoid valve 58 above and below the layer, respectively. The main control solenoid valve 56 is used to control the connection state between the input end of the water pump 55 and the water inlet 53 or the liquid storage tank 54, the branch solenoid valve 57 is used to control the connection state between the output end of the water pump 55 and the flushing device 59, and the branch solenoid valve 58 is used to control the connection state between the output end of the water pump 55 and the spray device 51 or the spray device 52.

[0051] It is worth noting that a spray device 51 and a spray device 52 are provided above and below each layer of the instrument rack 2, and only one set of common spray devices 51 and spray devices 52 is provided between two adjacent layers of the instrument rack 2. The spring switch 4 of each layer can control the working status of the spray devices 51 and spray devices 52 above and below the layer, so the control system 6 can control the pretreatment device 5 to rinse and moisturize the surgical instruments on each layer of the instrument rack 2 respectively.

[0052] Furthermore, in this embodiment, the control system 6 includes a plurality of key switches 61, a touch panel 62, a humidity sensor 63, a voice recognition controller 64 and a main control module 65.

The button switch 61, the touch panel 62, the humidity sensor 63, and the voice recognition controller 64 are electrically connected to the main control module 65 respectively. The main control module 65 determines whether to start the spray device 52 based on the comparison between the air humidity collected and reported by the humidity sensor 63 and the preset air humidity threshold.

[0053] Next, the working principle of a surgical instrument pretreatment device in this embodiment is described in detail so that those skilled in the art can better understand the present invention:

[0054] When leaving the factory, the speed of the servo motor and the duration of forward and reverse rotation are set in the main control module to ensure that the sprinkler pipe can rotate 180 degrees back and forth along its central axis; before use, it is necessary to make external power supply connections, external water supply and drainage connections.

[0055] When in use, push the instrument rack into the cabinet to complete the fixed installation, then place the surgical instruments that need to be pre-processed on the instrument rack, and remove the empty instrument rack in the cabinet and place it outside the cabinet;

[0056] The control system can be started by the power button. The touch panel supports displaying and controlling the on / off status of the main control solenoid valve, the shunt solenoid valve and each branch solenoid valve. When no other buttons are pressed, the on / off status of the main control solenoid valve, the shunt solenoid valve and the branch solenoid valve are all off. Only the branch solenoid valves above and below the corresponding layer where the instrument rack has been placed are displayed as being on at the same time as the water pump output end and the spray device.

[0057] When the spray button is pressed alone, the servo motor rotates according to the preset mode, the main control solenoid valve switches from the off state to the state of being connected with the water inlet and the water pump input end at the same time, the water pump output end is connected with the branch solenoid valve, and the spray devices above and below the instrument rack simultaneously rinse the surgical instruments on the instrument rack;

[0058] When the flush button is pressed alone, the main control solenoid valve switches from the off state to the on state with the water inlet and the water pump input end at the same time, and the branch solenoid valve switches from the off state to the on state with the water pump output end and the flushing device at the same time. The flushing device can flush the surgical instruments below; when the spray button and the flush button are pressed at the same time, the spray device and the flushing device can carry out cleaning work at the same time.

[0059] The main control module supports the preset air humidity threshold. When the air humidity collected and reported by the humidity sensor is lower than the preset air humidity threshold, the main control module can automatically switch the main control solenoid valve to a state where it is simultaneously connected to the liquid storage tank and the water pump input end, and the water pump output end is connected to the branch solenoid valve. The branch solenoid valves above and below the corresponding layer where the instrument rack has been placed are switched to a state where they are simultaneously connected to the water pump output end and the spray device. The spray devices above and below the instrument rack simultaneously spray and moisturize the surgical instruments on the instrument rack.

[0060] In addition, the voice recognition controller has customized the wake-up words and response words according to the instruction set of the above-mentioned control functions before leaving the factory, and supports executing operations corresponding to the instruction set through the voice control main control module.

[0061] Thus, the functions of a surgical instrument pretreatment device in this embodiment are as follows:

[0062] (1) Batch preprocessing function

[0063] By providing a multi-layer hollow plate-shaped instrument rack and matching hanging parts, multiple instrument racks can be placed in the cabinet as needed according to the number of surgical instruments to be preprocessed, thereby realizing the function of large-scale batch preprocessing of surgical instruments.

[0064] (2) Multi-angle spray function

[0065] By setting up a multi-layer instrument rack and a rotatable spray device, the placement and pre-treatment cleaning requirements of surgical instruments of various shapes can be met. Spray devices are installed on the left and right sides and the upper and lower parts of each layer of the instrument rack, and the spray device can rotate 180 degrees back and forth along the central axis, realizing a multi-angle spray function.

[0066] (3) Precision control function

[0067] By arranging a main control solenoid valve, a branch solenoid valve and multiple branch solenoid valves in the connecting pipeline of the pretreatment device, it is possible to achieve separate control of the spray device, the mist device and the flushing device, and by arranging a spring switch abutting against the instrument rack, the pretreatment device can realize the precise pretreatment control function of the surgical instruments on the instrument rack, and has the function of energy saving and emission reduction.

[0068] (4) Focus cleaning and self-cleaning functions

[0069] By setting a three-pronged rotating nozzle on the top of the cabinet, the three-pronged rotating nozzle will automatically rotate and spray water in multiple directions after water is passed through, so that the surgical instruments on the top instrument rack can be cleaned in a focused manner, thereby improving the cleaning effect of the surgical instruments. It can also be used to separately rinse the inside of the cabinet and has a self-cleaning function, reducing the workload of manual cleaning of the cabinet.
