Abstract
Description
Technical Field
[0001] This invention belongs to the field of wound cleaning technology, specifically referring to a wound cleaning device for neurosurgical care. Background Technology
[0002] When caring for neurosurgical patients, it is often necessary to clean wounds or incisions. Current cleaning devices generally use syringes or similar devices to spray cleaning fluid onto the target area. However, since the entire process is open, the splashing of liquid can easily contaminate the surrounding environment, and the exposure of the wound can also have an adverse effect on wound healing.
[0003] To avoid pollution, it is often necessary to collect and centrally treat the wastewater after cleaning. The spraying of clean water usually requires a pump to provide power, but the return of wastewater is generally not driven by a power source. This is because wastewater return pumps are easily contaminated and difficult to clean, and also because natural return can be collected, but at a slow speed. How to achieve relatively fast non-powered collection is a key problem to be solved in this field. Summary of the Invention
[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a wound cleaning device for neurosurgical care. Through a negative pressure control component, the negative pressure generated in the clean water chamber is transferred to the wastewater chamber during liquid flow, assisting in the rapid, non-powered return of the liquid. This maintains both the relative independence of the clean water and wastewater chambers while ensuring their connection in terms of air pressure. After the annular return chamber comes into contact with human skin, a closed space is formed inside the enclosed cleaning hood, thereby achieving temporary isolation between the clean area and the outside world. This ensures that the liquid does not contaminate the surrounding environment while maximizing rinsing efficiency.
[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a wound cleaning device for neurosurgical care, including a negative pressure reflux mechanism and a flushing mechanism. The negative pressure reflux mechanism includes a negative pressure control component and a dual-chamber separation storage component. The negative pressure control component is disposed in the dual-chamber separation storage component, and the flushing mechanism is disposed on both sides of the dual-chamber separation storage component.
[0006] Furthermore, the negative pressure control assembly includes a negative pressure control box, a sliding partition, and a plug. The sliding partition is engaged and slidably disposed in the negative pressure control box, dividing the negative pressure control box into two independent chambers of variable size.
[0007] The negative pressure control component can transfer the negative pressure generated in the clean water chamber to the wastewater chamber during the liquid flow process, thereby assisting the rapid non-powered return of the liquid; it can maintain the relative independence between the clean water chamber and the wastewater chamber, while maintaining the connection between the two in terms of air pressure.
[0008] Preferably, the dual-chamber separation storage assembly includes a storage tank and a fixed partition, the fixed partition being fixedly connected to the storage tank, and the storage tank being divided into a clean water chamber and a wastewater chamber by the fixed partition.
[0009] As a further preferred embodiment of the present invention, the negative pressure control box is provided with a first port and a second port, the first port and the second port being connected to the sewage chamber and the clean water chamber respectively, and the negative pressure control box is also provided with a first connector and a second connector, the plug being detachably disposed in the first connector and the second connector.
[0010] When the plug is opened, it helps to balance the internal and external air pressure and can be used to reset the air pressure before use.
[0011] As a further preferred embodiment of the present invention, the negative pressure control box is also provided with a handle on its top.
[0012] Furthermore, the flushing mechanism includes an inlet assembly, a flushing assembly, and a return hose. The inlet assembly is located on the side of the storage tank near the clean water chamber and communicates with the clean water chamber. The return hose is located on the side of the storage tank near the wastewater chamber and communicates with the wastewater chamber.
[0013] Preferably, the flushing assembly is located between the liquid inlet assembly and the return hose.
[0014] As a further preferred embodiment of the present invention, the liquid inlet assembly includes a liquid inlet pump and a liquid inlet pipe. The liquid inlet pump is located on the side of the storage tank near the clean water chamber and communicates with the clean water chamber. The liquid inlet pipe is located on the liquid inlet pump.
[0015] After the annular reflux chamber comes into contact with human skin, the closed cleaning hood can form a sealed space; thus, the clean area is temporarily isolated from the outside world, which can not only ensure that the liquid does not contaminate the surrounding environment, but also maximize the rinsing efficiency.
[0016] The rinsing assembly includes a closed cleaning hood and a straight shower head. The straight shower head is located at the end of the liquid inlet pipe, and the closed cleaning hood is located outside the straight shower head. The end of the closed cleaning hood is provided with an annular reflux chamber, and the annular reflux chamber is provided with a reflux port.
[0017] Preferably, the return hose is connected to the annular return cavity.
[0018] The beneficial effects achieved by the present invention using the above structure are as follows:
[0019] (1) The negative pressure control component can transfer the negative pressure generated in the clean water chamber to the sewage chamber during the liquid flow process to assist the liquid to flow back quickly without power; it can maintain the relative independence between the clean water chamber and the sewage chamber, and also maintain the connection between the two in terms of air pressure.
[0020] (2) When the plug is opened, it has the function of balancing the internal and external air pressure and can be used to reset the air pressure before use.
[0021] (3) After the annular reflux chamber comes into contact with human skin, a closed space can be formed inside the closed cleaning hood; thus, the cleaning area is temporarily isolated from the outside world, which can ensure that the liquid will not pollute the surrounding environment and can also improve the rinsing efficiency as much as possible.

Therefore, they should not be construed as limitations on this invention.
[0032] like Figures 1-6 As shown, the present invention proposes a wound cleaning device for neurosurgical care, including a negative pressure reflux mechanism 1 and a flushing mechanism 2. The negative pressure reflux mechanism 1 includes a negative pressure control component 3 and a dual-chamber separation storage component 4. The negative pressure control component 3 is disposed in the dual-chamber separation storage component 4, and the flushing mechanism 2 is disposed on both sides of the dual-chamber separation storage component 4.
[0033] The negative pressure control assembly 3 includes a negative pressure control box 5, a sliding partition 6, and a plug 7. The sliding partition 6 is engaged and slidably disposed in the negative pressure control box 5, dividing the negative pressure control box 5 into two independent chambers of variable size.
[0034] The negative pressure control component 3 can transfer the negative pressure generated in the clean water chamber 15 to the wastewater chamber 16 during the liquid flow process, so as to assist the rapid non-powered return of the liquid; it can maintain the relative independence between the clean water chamber 15 and the wastewater chamber 16, while maintaining the connection between the two in terms of air pressure.
[0035] The dual-chamber separation storage assembly 4 includes a storage tank 8 and a fixed partition 9. The fixed partition 9 is fixedly connected to the storage tank 8, and the storage tank 8 is divided into a clean water chamber 15 and a wastewater chamber 16 by the fixed partition 9.
[0036] The negative pressure control box 5 is provided with a first port 10 and a second port 11. The first port 10 and the second port 11 are respectively connected to the sewage chamber 16 and the clean water chamber 15. The negative pressure control box 5 is also provided with a first connector 12 and a second connector 13. The plug 7 is detachably installed in the first connector 12 and the second connector 13.
[0037] When the plug 7 is opened, it has the function of balancing the internal and external air pressure and can be used to reset the air pressure before use.
[0038] The negative pressure control box 5 is also equipped with a handle 14 on its top.
[0039] The flushing mechanism 2 includes an inlet assembly 17, a flushing assembly 18, and a return hose 19. The inlet assembly 17 is located on the side of the storage tank 8 near the clean water chamber 15 and communicates with the clean water chamber 15. The return hose 19 is located on the side of the storage tank 8 near the sewage chamber 16 and communicates with the sewage chamber 16.
[0040] The flushing assembly 18 is located between the liquid inlet assembly 17 and the return hose 19.
[0041] The liquid inlet assembly 17 includes a liquid inlet pump 20 and a liquid inlet pipe 21. The liquid inlet pump 20 is located on the side of the storage tank 8 near the clean water chamber 15 and is connected to the clean water chamber 15. The liquid inlet pipe 21 is located on the liquid inlet pump 20.
[0042] After the annular reflux chamber 24 comes into contact with human skin, the closed cleaning hood 22 can form a closed space; thus achieving temporary isolation between the clean area and the outside world, ensuring that the liquid will not contaminate the surrounding environment, and maximizing rinsing efficiency.
[0043] The rinsing assembly 18 includes a closed cleaning hood 22 and a straight shower head 23. The straight shower head 23 is located at the end of the liquid inlet pipe 21. The closed cleaning hood 22 is located outside the straight shower head 23. The end of the closed cleaning hood 22 is provided with an annular reflux chamber 24, and the annular reflux chamber 24 is provided with a reflux port 25.
[0044] The return hose 19 is connected to the annular return chamber 24.
[0045] Figure 5 The dashed arrows in the diagram indicate the direction of movement of the liquid or components.
[0046] In practical use, the user first needs to put the closed cleaning cover 22 on the area to be cleaned. After the annular return chamber 24 is in close contact with the skin, a closed space can be formed inside the closed cleaning cover 22. Then, the liquid pump 20 is started, and the clean cleaning liquid in the clean water chamber 15 enters the straight-through shower head 23 through the liquid inlet pipe 21, and then the target area is rinsed in a slow spray manner.
[0047] Since the interior of the enclosed cleaning hood 22 is isolated from the outside, the liquid will not splash and contaminate the external environment. Instead, it will enter the annular return chamber 24 from the return port 25 and then return to the sewage chamber 16 through the return hose 19.
[0048] Since the clean water chamber 15 and the wastewater chamber 16 are completely separated and the gases cannot be exchanged, the liquid and gas in the wastewater chamber 16 will not contaminate the clean water chamber 15.
[0049] After the liquid in the clean water chamber 15 is discharged through the liquid inlet pipe 21, the air pressure inside the clean water chamber 15 will decrease. Therefore, a pressure difference will be generated between the clean water chamber 15 and the sewage chamber 16. By sliding the sliding partition 6, the pressure difference between the clean water chamber 15 and the sewage chamber 16 can be balanced, and the negative pressure state of the clean water chamber 15 can be transferred to the sewage chamber 16, which will also generate negative pressure in the sewage chamber 16.
[0050] The liquid in the annular reflux chamber 24 can naturally flow back to the sewage chamber 16 through the reflux hose 19, but the speed is relatively slow. When the sewage chamber 16 is under negative pressure, the flow rate of the liquid in the reflux hose 19 can be accelerated. Therefore, the liquid can be quickly refluxed without the need for a reflux pump.
