Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of infection prevention and isolation devices, specifically an infection prevention and isolation device for pediatric clinical medicine. Background Technology
[0002] In the field of pediatric clinical medicine, the proper handling of infectious medical waste is a crucial step in preventing the spread of infection. Pediatric patients have weaker immune systems, and the germs and viruses carried in medical waste are more infectious and harmful. Improper handling can easily lead to cross-infection, seriously threatening the health of both patients and healthcare workers.
[0003] Currently, while traditional pedal-operated trash cans can meet basic waste disposal needs, they are significantly inadequate in terms of infection prevention. Most of these trash cans only have simple opening and closing functions and lack effective disinfection measures for medical waste, failing to kill germs in the waste in a timely manner. This allows germs to grow and spread inside the trash can, increasing the risk of infection.
[0004] While some improved trash cans are equipped with disinfectant spray devices, the spray control is often inadequate. For example, disinfectant may start spraying when medical waste is disposed of, which could not only cause unnecessary harm to medical staff but also reduce the effectiveness of the disinfectant. Furthermore, existing disinfection devices often cannot flexibly adjust the disinfection time according to actual conditions, making it difficult to meet the disinfection needs of different scenarios. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an infection prevention and isolation device for pediatric clinical medicine.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] A pediatric clinical medical infection prevention and isolation device, comprising:
[0008] The foot-operated trash can has an openable and closable lid on top.
[0009] The disinfectant spray nozzle is located on the inner surface of the bucket lid and is connected to an external disinfectant pump.
[0010] A pedal is located on the front side of the foot-operated trash can and is linked to the lid.
[0011] The first hydraulic component has its bottom end fixed to the body of the foot-operated trash can and its top end abutting against the pedal.
[0012] The triggering component includes a second hydraulic component that communicates with the first hydraulic component. The top end of the hydraulic rod of the second hydraulic component is provided with a conductive post. During the lifting stroke of the hydraulic rod, a pair of elastic conductive sheets that cooperate with the conductive post are provided. The elastic conductive sheets are electrically connected to the disinfectant pump.
[0013] An insulating sheet is rotatably connected to the circumferential surface of a conductive post. The maximum rotation angle of the insulating sheet is set to selectively block the contact surface between the conductive post and the elastic conductive sheet. The contact distance between the conductive post and the elastic conductive sheet is positively correlated with the conduction time of the disinfectant pump circuit.
[0014] Preferably, it also includes a counterweight, which is detachably mounted on the top of the hydraulic rod, for adjusting the descent speed of the conductive column by adjusting the weight of the counterweight.
[0015] Preferably, the first hydraulic component and the second hydraulic component form a communicating vessel structure through hydraulic pipelines.
[0016] Preferably, the top and bottom ends of the elastic conductive sheet are provided with arc-shaped flared portions to guide the entry of the conductive post.
[0017] Preferably, the elastic conductive sheet is symmetrically arranged on the left and right sides of the hydraulic rod lifting path, and its contact end has an arc-shaped concave structure facing the conductive column.
[0018] Preferably, the disinfectant spray nozzles are arranged in a ring array on the inner surface edge of the lid, and the axis of the spray nozzles forms a 30-45° tilt angle with the plane of the lid.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] 1. Effective infection prevention: The disinfectant spray nozzles are arranged in a ring array on the inner edge of the lid, and the axis of the nozzles forms a 30-45° angle with the lid plane, which allows the disinfectant to be sprayed evenly inside the container, effectively disinfecting the medical waste and preventing infection.
[0021] 2. Reasonable control of disinfectant spraying: By using the combination of components such as hydraulic rods, conductive columns, insulating sheets and elastic conductive sheets, disinfectant spraying is achieved after the lid is closed, avoiding the impact of disinfectant spraying on medical staff when disposing of medical waste;
[0022] 3. Adjustable disinfection time: The descent speed of the conductive column can be adjusted according to actual needs by using a counterweight that can be detachably installed at the top of the hydraulic rod. This allows for adjustment of the contact time between the conductive column and the elastic conductive sheet, ultimately enabling the adjustment of the disinfectant spraying time.

[0032] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0033] Example
[0034] like Figure 1-7As shown, a pediatric clinical medical infection prevention and isolation device includes a foot-operated trash can body 1, a disinfectant spray nozzle 2, a pedal 3, a first hydraulic component 4, a trigger component 5, a second hydraulic component 51, a hydraulic rod 52, a counterweight 53, a conductive column 54, an insulating sheet 541, and an elastic conductive sheet 542.
[0035] Foot-operated trash can body 1: The main body of the device, equipped with an openable and closable lid on top, for storing pediatric medical waste that is susceptible to infection.
[0036] Disinfectant spray nozzles 2: They are arranged in a ring array on the inner surface edge of the lid, and the axis of the nozzles forms a 30-45° angle with the lid plane. They are connected to an external disinfectant pump and can spray disinfectant evenly.
[0037] Pedal 3: Located on the front side of the foot-operated trash can body 1, and linked to the lid. The lid can be opened and closed by stepping on the pedal 3.
[0038] First hydraulic component 4: The bottom end is fixed inside the foot-operated trash can body 1, and the top end is connected to the pedal 3 to transmit the stepping force.
[0039] Trigger Component 5
[0040] The second hydraulic component 51 forms a communicating vessel structure with the first hydraulic component 4 through a hydraulic pipeline, which can convert the pressure transmitted by the first hydraulic component 4 into the lifting and lowering motion of the hydraulic rod 52.
[0041] Hydraulic rod 52: The top end is provided with a conductive column 54, and a pair of elastic conductive plates 542 that cooperate with the conductive column 54 are provided in its lifting stroke. The elastic conductive plates 542 are electrically connected to the disinfectant pump.
[0042] Counterweight 53: It can be detachably installed on the top of the hydraulic rod 52. It is used to adjust the descent speed of the conductive column 54 by adjusting the weight of the counterweight 53, that is, the descent speed of the conductive column 54, which is also the contact conduction time between the conductive column 54 and the elastic conductive sheet 542.
[0043] Conductive post 54: An insulating sheet 541 is rotatably connected to its circumferential surface. The maximum rotation angle of the insulating sheet 541 is set to selectively block the contact surface between the conductive post 54 and the elastic conductive sheet 542. The insulating sheet 541 and the conductive post 54 are rotatably connected by a slider and a groove.
[0044] Insulating sheet 541: Rotatably connected to the circumferential surface of conductive post 54. It can be rotated to adjust the contact surface between conductive post 54 and elastic conductive sheet 542, thereby controlling the circuit conduction. The friction between insulating sheet 541 and elastic conductive sheet 542 is greater than the rotational force.
[0045] Elastic conductive sheet 542: Symmetrically arranged on the left and right sides of the lifting path of hydraulic rod 52, with arc-shaped flared ends at the top and bottom, and the contact end having an arc-shaped concave structure facing the conductive post 54, used to guide the conductive post 54 into place and make contact with the conductive post 54 to achieve circuit conduction.
[0046] Opening and closing the bucket lid
[0047] When medical staff need to dispose of easily infectious pediatric medical waste, they step on the pedal 3 on the front side of the foot-operated trash can 1. The movement of the pedal 3 is transmitted through the first hydraulic component 4, whose bottom end is fixed inside the foot-operated trash can 1, transmitting the stepping force. Since the first hydraulic component 4 and the second hydraulic component 51 form a communicating vessel structure through hydraulic pipelines, pressure changes within the first hydraulic component 4 are transmitted to the second hydraulic component 51, causing the hydraulic rod 52 in the second hydraulic component 51 to move up and down. Simultaneously, the pedal 3 is linked to the lid; when the pedal 3 is stepped on, the lid opens for easy disposal of medical waste; when the pedal 3 is released, the lid closes under the action of a corresponding reset mechanism (generally the return mechanism of the hydraulic system and the lid's own reset device).
[0048] Disinfectant spraying control
[0049] The hydraulic rod 52 has a conductive post 54 at its top. During its lifting stroke, there is a pair of elastic conductive sheets 542 that cooperate with the conductive post 54, and the elastic conductive sheets 542 are electrically connected to an external disinfectant pump. When the pedal 3 is pressed to raise the hydraulic rod 52, the conductive post 54 rises with the hydraulic rod 52. Initially, the insulating sheet 541 contacts the elastic conductive sheet 542. Under the action of friction, the insulating sheet 541 rotates to the side or is positioned to the side under the action of gravity, so that the conductive post 54 does not contact the elastic conductive sheet 542 (e.g., Figure 7 As shown), the circuit is not conductive, the disinfectant pump does not work, and after the user places the container and closes the lid, the conductive post 54 moves downward under the weight of the counterweight 53 and the hydraulic rod 52. When the conductive post 54 moves downward, the insulating sheet 541 contacts the elastic conductive sheet 542. Under the action of friction, the insulating sheet 541 rotates upward (as shown). Figure 6 As shown, the conductive post 54 contacts the elastic conductive sheet 542, at which point the circuit is connected and the disinfectant pump starts to work. The disinfectant is sprayed out from the disinfectant spray holes 2, which are arranged in a ring array along the inner surface edge of the lid. The axis of the spray holes forms a 30-45° angle with the lid plane, which allows the disinfectant to be sprayed evenly inside the bucket, disinfecting the medical waste and preventing infection.
[0050] When the conductive post 54 detaches from the elastic conductive sheet 542, the circuit is not connected, and the disinfectant pump stops working, thus avoiding the waste of disinfectant due to prolonged operation without circuit connection and the disinfectant pump not working.
[0051] Adjustment of disinfection time
[0052] Counterweight Adjustment: The counterweight 53 is detachably installed at the top of the hydraulic rod 52. By adjusting the weight of the counterweight 53, the descent speed of the conductive column 54 can be changed. When the counterweight is heavier, the conductive column 54 descends faster, and the contact time between the conductive column 54 and the elastic conductive sheet 542 is shortened; conversely, when the counterweight is lighter, the conductive column 54 descends slower, and the contact time is prolonged. This allows for adjustment of the disinfectant spraying time according to actual needs.
[0053] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
