Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a portable disinfection device. Background Technology

[0002] The "Chemical Contamination Decontamination Device" employs a "local decontamination + immediate waste recovery" method. Its main components include a decontamination brush head, a decontamination spray nozzle, a negative pressure recovery device, and a wastewater tank. The decontamination brush head creates a semi-enclosed decontamination surface on the contaminated skin, separated from the surrounding area by a soft brush. Decontamination solution is sprayed onto this surface. Waste decontamination solution, after reacting with the contaminant, is immediately and completely recovered by the negative pressure of the brush head. During the decontamination process, the decontamination solution is neither sprayed outside nor flows out of the decontamination surface. After decontamination, no waste decontamination solution remains on the surface, facilitating further processing and posing no harm to decontamination personnel. In on-site medical emergency rescue involving nuclear accidents, the decontamination device is typically used in conjunction with general medical kits. For example, during a nuclear accident, a first-line aid station can be established outside the contaminated area, and the decontamination device can be used to decontaminate and decontaminate radiation-exposed patients.

[0003] The Chinese Patent Network discloses "A Decontamination Device for Automatic Wastewater Discharge", with the publication number CN220632690U. It includes a box (1), inside which is a main body (2) of a recovery-type local decontamination device. Inside the main body (2) of the recovery-type local decontamination device, there is a sewage tank (3). On one side of the sewage tank (3), there is a sewage pump (4) for discharging the waste liquid inside the sewage tank (3) to the outside. The outer periphery of the box (1) is surrounded by a waste liquid storage component (5). The inlet of the waste liquid storage component (5) is connected to the outlet of the sewage pump (4) to collect the waste liquid discharged from the sewage tank (3). The waste liquid storage component (5) includes at least two conduits (501). The conduits (501) have a common inlet. Each conduit (501) is connected to a storage unit (502). The storage units (502) are evenly distributed on the outside of the box (1). The waste liquid storage component can make the waste liquid from the sewage tank evenly transported to the outside of the box, avoiding the waste liquid from accumulating in only one place outside the box when it is discharged, which would cause the center of gravity of the decontamination device to be unstable. The waste liquid is evenly distributed outside the box, reducing the risk of the center of gravity of the decontamination device box being unstable and making it easier for the operator to lift the decontamination device.

[0004] Since decontamination devices are used in on-site medical emergency rescue, they need to be as simple to operate as possible to reduce the difficulty of operation for medical staff and improve the efficiency of medical operations. However, existing technologies have decontamination liquid pipes and decontamination waste liquid recovery pipes, with different pipes performing different functions. This leads to medical staff having to change pipes to meet the needs of medical operations, resulting in low efficiency and increased difficulty of operation for medical staff. When decontamination and decontamination are required for a large number of patients, the increased difficulty of operation over time can easily exacerbate the fatigue of medical staff and increase the probability of subsequent operational errors.

[0034] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4In one or more embodiments, a portable decontamination device is provided, comprising: a housing 100, wherein a waste liquid tank 101 is disposed inside the housing 100, and a negative pressure air pump 102 and a water pump 103 are disposed on the surface of the waste liquid tank 101. The negative pressure air pump 102 is used to draw negative pressure into the waste liquid tank 101. A waste liquid inlet pipe 104 is disposed on one side of the waste liquid tank 101. The output end of the water pump 103 is connected to a decontamination liquid outlet pipe 105. The other ends of the decontamination liquid outlet pipe 105 and the waste liquid inlet pipe 104 are connected to a connecting seat 106. A waste liquid outlet pipe 107 is connected to the other side of the waste liquid tank 101. The input end of the water pump 103 is connected to a decontamination liquid inlet pipe 108. The connecting seat 106, the waste liquid outlet pipe 107, and the decontamination liquid outlet pipe 105 are all... Extending to the outside of the housing 100, the surface of the waste liquid outlet pipe 107 is provided with a valve 109, and the top of the housing 100 is provided with a power supply interface 110; a hose 200, one end of which is detachably connected to the surface of the connecting seat 106, and the other end of which is detachably connected to a handle 201, the other end of which is connected to a nozzle body 202, a water pipe connector 203 is provided inside the nozzle body 202, one end of which is connected to a nozzle 204, an adapter seat 205 is provided on the surface of the nozzle body 202, the nozzle 204 passes through the adapter seat 205, and the other end of the decontamination liquid outlet pipe 105 passes through the inner cavity of the hose 200 and the inner cavity of the handle 201 and is connected to the other end of the water pipe connector 203.

[0035] In this embodiment, before use, the decontamination liquid inlet pipe 108 is connected to the decontamination liquid tank, and one end of the hose 200 is detachably connected to the connector 106. During this process, the decontamination liquid outlet pipe 105 is passed through the hose 200 and the handle 201, and the decontamination liquid outlet pipe 105 is connected to the water pipe connector 203. Then, the hose 200 is connected to the handle 201, and the nozzle body 202 is brought into contact. At the same time, the water pump 103 and the negative pressure air pump 102 are started. The decontamination liquid flows sequentially through the decontamination liquid inlet pipe 108, the decontamination liquid outlet pipe 105, the water pipe connector 203, and the nozzle. The nozzle 204 sprays disinfectant onto the patient's skin to achieve disinfection. The splashed disinfectant passes through the filter 207 and flows sequentially through the nozzle body 202, handle 201, and waste liquid inlet pipe 104 into the waste liquid tank 101, thus achieving simultaneous disinfection and waste liquid recovery. During this process, medical staff only need to control a single hose 200, reducing the difficulty of operation and improving medical efficiency. When it is time to discharge waste, the valve 109 is controlled to allow the waste liquid outlet pipe 107 to flow, thereby allowing the waste liquid in the waste liquid tank 101 to flow out through the waste liquid outlet pipe 107.

[0036] The specific structure and working principle of nozzle 204 are based on existing technology in this field, and will not be repeated here.

[0037] Please see Figure 1 , Figure 2 and Figure 5 In some embodiments, a circuit box 111 is provided on the surface of the waste liquid tank 101, and a balance sensor is provided inside the circuit box 111 to monitor the balance of the tank 100. A liquid level sensor is provided inside the circuit box 111 to monitor the liquid level in the waste liquid tank 101. A membrane touch button 112 and a control display unit 113 are provided on the top of the tank 100. The liquid level sensor, the balance sensor, the negative pressure fan 102, and the water pump 103 are all electrically connected to the membrane touch button 112 and the control display unit 113. The control display unit 113 has voice broadcast and indicator light functions. A power supply interface 110 is provided on the top of the tank 100.

[0038] In this embodiment, the selection of the membrane touch button 112 and the control display unit 113 is performed by medical staff according to the selected function during actual operation. Simultaneously, voice prompts and light displays can be used to guide medical staff to the selected function, ensuring accuracy and reducing the probability of medical operation errors. The balance sensor monitors whether the tank 100 is level to prevent tilting from affecting the waste liquid storage capacity of the waste liquid tank 101. An alarm is triggered when the tank 100 tilts more than 35 degrees. The control display unit 113 has a constant red fault light and an off blue power light, and repeatedly announces "The machine is tipping over, please right it"; the liquid level sensor monitors the liquid level in the waste liquid tank 101. When the waste liquid tank is full, the control display unit 113's red fault light goes off and the blue power light flashes (on for 1 second and off for 1 second), and announces once "The waste liquid tank is full, please drain the waste liquid"; the power supply interface 110 can be connected to a power source to power the electrical structures such as the negative pressure fan pump 102, water pump 103, balance sensor, and liquid level sensor.

[0039] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In some embodiments, a hairbrush 206 is detachably connected to the surface of the adapter 205, a handle 114 is provided on the top of the housing 100, an exhaust port is provided on the housing 100, a filter screen 207 is provided on the surface of the nozzle body 202, the surface of the adapter 205 abuts against the surface of the filter screen 207, and a plurality of perforations are provided on the surface of the adapter 205. The plurality of perforations are equally spaced around the center of the adapter 205, and the center of the nozzle 204 is on the same axis as the center of the adapter 205.

[0040] In this embodiment, the hairbrush 206 is designed to facilitate hair combing by medical staff without requiring direct operation, thus reducing direct contact between medical staff and patients. The hairbrush 206 and the nozzle body 202 are detachably connected and can be selectively installed according to actual conditions. The exhaust vent allows air circulation within the housing 100, alleviating heat buildup and extending the lifespan of the electrical structures in the negative pressure pump 102, water pump 103, and circuit box 111. The filter 207 prevents impurities from entering the waste liquid tank 101, reducing the difficulty of discharge and thus extending the lifespan of the waste liquid tank 101.

[0041] Specifically, the working principle of the portable decontamination device provided in this application is as follows:

[0042] Before use, connect the disinfectant inlet pipe 108 to the disinfectant tank and detachably connect one end of the hose 200 to the connector 106. During this process, pass the disinfectant outlet pipe 105 through the hose 200 and handle 201, and connect the outlet pipe 105 to the water pipe connector 203. Then connect the hose 200 to the handle 201 and make contact with the nozzle body 202. Simultaneously, start the water pump 103 and the negative pressure air pump 102, allowing the disinfectant to flow sequentially through the nozzle. The system consists of an inlet pipe 108, a disinfectant outlet pipe 105, a water pipe connector 203, and a nozzle 204. The nozzle 204 sprays the disinfectant onto the patient's skin to achieve the disinfection function. After splashing, the disinfectant passes through the filter screen 207 and flows sequentially through the nozzle body 202, the handle 201, and the waste liquid inlet pipe 104 into the waste liquid tank 101. This achieves simultaneous disinfection and waste liquid recovery. During this process, medical staff only need to control a single hose 200, reducing the difficulty of operation and improving medical efficiency.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
