Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of medical device recycling, and specifically refers to an anti-infection device for recycling medical devices for operating room nursing. Background Art
[0002] In operating room nursing work, a large number of medical devices are usually needed, and these medical devices need to be recycled according to their materials after use. For example, medical devices made of plastic and rubber are usually disposable items (such as syringes, gloves, masks, etc.). After the operation, they need to be collected and recycled at designated recycling points. Some medical devices made of metal materials usually need to be centrally disinfected after use, and then the consumable parts will be replaced and reused. Traditional medical device recycling methods have many disadvantages and are very likely to cause cross-infection risks. Instruments used in the operating room often carry a large number of pathogens, blood and other contaminants. If the recycling process lacks effective protection and disinfection measures, these contaminants will spread in the recycling environment, which will not only pose a direct threat to the health of medical staff, but may also contaminate other clean areas and increase the incidence of hospital infections.
[0003] In the past, recycling devices were mostly simple containers that lacked partitioning for the collection of instruments, resulting in the mixing of instruments of different types and degrees of contamination, further exacerbating the risk of infection. At the same time, when instruments were put into recycling devices, there were no effective sealing and disinfection methods, and outside air could easily enter the recycling devices, creating conditions for the spread of pathogens. Summary of the invention

The instruments are disinfected the moment they enter the recovery device, thereby reducing the possibility of the spread of pathogens in the device, effectively reducing the risk of cross infection, and being able to accurately classify instruments according to their materials, thereby improving the efficiency of subsequent instrument processing.

The end of the partition plate is fixedly connected to a feeding channel, the upper circular hole plate is rotatably sleeved on the top end of the feeding channel, and the lower circular hole plate is rotatably sleeved on the bottom end of the feeding channel. The blades are arranged in a circular array in multiple groups with the center of the upper circular hole plate as the axis, and the multiple groups of blades are spliced into a circular structure. The blades have two groups of corners away from the center of the circle, one group of corners of the blades is hinged to the connecting rod, and the other group of corners of the blades is hinged to the top wall of the feed bin, and the other end of the connecting rod is hinged to the top wall of the upper circular hole plate, the torsion spring is sleeved on the hinge column between the connecting rod and the upper circular hole plate, the torsion spring is connected between the connecting rod and the top wall of the feed bin, and the bottom of the lower circular hole plate has the same structure as the top of the upper circular hole plate.
[0007] As a preferred technical solution of the present invention, the centers of the discharge port, the discharge channel and the feeding port are on the same vertical line, and two groups of partition plates divide the cavity between the inner wall of the feed bin, the upper circular hole plate, the lower circular hole plate and the discharge channel into a driving cavity and a disinfectant liquid cavity. An infusion tube is connected to the bottom of the liquid storage cylinder, and the infusion tube passes through the feed bin and is connected with the disinfectant liquid cavity. The disinfectant solution in the liquid storage cylinder is transported to the disinfectant liquid cavity through the infusion tube, ensuring that the disinfectant solution in the disinfectant liquid cavity is always in a filled state.
[0008] As a preferred technical solution of the present invention, the pressurized spray mechanism includes a rubber airbag, a spray pipe and a piston cylinder, the rubber airbag is fixedly installed on the inner wall of the disinfectant liquid cavity, the spray pipe is evenly arranged in multiple groups and passes through the feeding channel, one end of the spray pipe is connected to the disinfectant liquid cavity, and the other end of the spray pipe is connected to the feeding channel, the piston cylinder is fixedly installed on the outer wall of the feed bin and is located in the protective cover, the base end of the piston cylinder is connected with an air supply pipe, the air supply pipe passes through the protective cover and the side wall of the feed bin and is connected with the rubber airbag, a piston plate is slidably arranged in the piston cylinder, a piston rod is connected to the side wall of the piston plate, the piston rod slides through the side wall of the piston cylinder, the piston rod is transmission-connected to the alternating drive assembly, the alternating drive assembly drives the piston rod to move, pressurizes the disinfectant solution in the disinfectant liquid cavity, and realizes spray disinfection of the medical devices delivered in the feeding channel, and the medical devices are disinfected at the moment they enter the recovery device, effectively reducing the spread of pathogens.

The one-way valve 1 on the infusion tube allows the disinfectant solution in the liquid storage cylinder to be transported toward the disinfectant liquid cavity, while the one-way valve 2 on the spray tube only allows the disinfectant solution in the disinfectant liquid cavity to be transported toward the downward material channel.
[0010] Compared with the prior art, the present invention adopts the above structure to achieve the following beneficial effects: 1. Through the linkage setting of the alternating double-capping mechanism and the pressurized spraying mechanism, when the upper circular hole plate of the alternating double-capping mechanism is opened and the instrument enters the feeding channel from the feeding port, the driving motor is operated, and the incomplete gear 2 of the pressurized spraying mechanism is driven to rotate synchronously, and the incomplete gear 2 drives the rack to move, so that the piston plate conveys the gas in the piston cylinder to the rubber airbag. The rubber airbag expands to pressurize the disinfectant solution in the disinfectant liquid cavity, and sprays it from the spray pipe to spray and disinfect the instrument entering the feeding channel. This linkage ensures that the instrument is disinfected at the moment of entering the recovery device, reducing the possibility of the spread of bacteria in the device; 2. When the lower circular hole plate is opened and the instrument enters the partition bin from the discharge port, since the upper circular hole plate is closed, the spray disinfection is mainly aimed at the residual bacteria in the discharge channel, further ensuring that the instruments entering the partition bin are in a relatively clean state to avoid cross infection; 3. The alternating double-capping mechanism accurately delivers the sterilized instruments to the magnetic conveyor belt of the partition collection mechanism through the feeding port. The conveying motor of the partition collection mechanism drives the magnetic conveyor belt to operate and transport the instruments. The timing switch function of the alternating double-capping mechanism cooperates with the continuous transportation of the partition collection mechanism, so that the instruments can enter the partition collection bin in an orderly manner, thereby improving the recycling efficiency. 4. The alternating opening and closing of the upper and lower circular hole plates ensures the relative isolation between the feed bin and the partition bin, preventing the recovered instruments in the partition bin from being contaminated by the new instruments put into the feed bin; 5. After the pressurized spray mechanism disinfects the instruments, the partition collection mechanism can timely transport and classify the disinfected instruments. The rapid transport of the partition collection mechanism also facilitates the subsequent instrument processing and improves the overall work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
