Description

Technical Field

[0001] The utility model relates to the technical field of medical nursing devices, in particular to a portable anti-dumping closed negative pressure drainage device. Background Art

[0002] After a wound is infected, if it is not treated technically for a long time, it is easy to become infected and festered. In severe cases, drainage is required. Drainage refers to the drainage of fluids from tissue fissures, body cavities, and organ cavities away from their original locations and out of the body. Negative pressure drainage is widely used in clinical practice. Closed negative pressure drainage (VSD) is a common wound treatment method that can protect the wound, control infection, promote healing, etc. It is widely used in clinical practice. However, in the field, the traditional negative pressure drainage device is used to treat combat wounds, and there are the following problems:

[0003] It needs to be installed on the central negative pressure or negative pressure suction device, both of which require power and cannot be carried around;

[0004] The pipeline is complicated and can easily fall off accidentally during transportation;

[0005] If the device falls over, the liquid will easily flow back or out, causing pollution;

[0006] At present, there are many negative pressure drainage devices used in clinical practice. The basic working principle is to generate negative pressure in the same cavity. The negative pressure source can be central negative pressure, and they are all used in fixed rooms, such as central negative pressure drainage bottles / bags for surgery. However, this type of device is highly dependent on central negative pressure. When the central negative pressure stops or there is no central negative pressure in the use environment, this type of device cannot be used. Utility Model Content

[0024] In the figure, 1 is a vacuum pump; 2 is a pressure gauge; 3 is an adjusting knob; 4 is a battery; 5 is a first drainage tube; 6 is a dressing; 7 is a flow regulating switch; 8 is a first one-way valve; 9 is a spring; 10 is a hose; 11 is a floating air inlet; 12 is a sewage tank; 13 is a sterile liquid storage tank; 14 is a piston plate; 15 is a water inlet pipe; 16 is a third drainage tube; 17 is a third one-way valve; 18 is a second one-way valve. DETAILED DESCRIPTION

[0025] The utility model will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0026] like Figure 1 As shown, a portable anti-dumping closed negative pressure drainage device comprises: a sterile liquid supply mechanism, a sewage recovery mechanism, and a negative pressure generating mechanism;

[0027] The sterile liquid supply mechanism includes: a sterile liquid storage tank 13, and the output end of the sterile liquid storage tank 13 is equipped with a first drainage tube 5 for flushing the wound; the sewage recovery mechanism includes: a sewage tank 12, and the sewage tank 12 is provided with an inlet pipe 15 for collecting waste water after the wound is flushed, and the sewage tank 12 is connected to the negative pressure generating mechanism.

[0028] Furthermore, the water outlet end of the first drainage tube 5 is provided with a dressing 6, the first drainage tube 5 is provided on one side of the dressing 6, and the water inlet pipe 15 is provided on the other side of the dressing 6. Since the flushing liquid flow rate adjusted by the flow regulating switch 7 is much smaller than the flow rate of the negative pressure air generated by the vacuum pump 1 by the regulating knob 3 for adjusting the speed / pressure, the liquid in the dressing 6 can be discharged in time through the first drainage tube 5, preventing leakage or excessive waste liquid from remaining in the dressing 6.

[0029] A third drainage pipe 16 connected to the negative pressure generating mechanism is arranged in the sewage tank 12. A floating air inlet port 11 is installed at the output port of the hose 10. The drainage pipe 10 connected to the floating air inlet port 11 is a hose, and the angle of the drainage pipe 10 can be changed arbitrarily to prevent liquid from entering the drainage pipe 10.

[0030] The first drainage pipe 5 is provided with a first one-way valve 8 , and the water inlet pipe 15 is provided with a second one-way valve 18 .

[0031] In order to control the flow rate of the cleaning liquid, a flow regulating switch 7 is provided on the first drainage tube 5 ; the third drainage tube 16 is a U-shaped tube; and a third one-way valve 17 is provided on the third drainage tube 16 .

[0032] In addition, the negative pressure generating mechanism of the present invention includes: a vacuum pump 1, a pressure gauge 2, a speed / pressure adjustment knob 3, and a battery 4, and can adjust the pressure according to demand.

[0033] The sterile liquid storage tank 13 is provided with a pressing component, and the water inlet pipe 15 is provided at the bottom of the sterile liquid storage tank 13, and the sterile liquid is discharged by the pressing component. The sterile liquid storage tank 13 is mainly used to store liquids such as sterile saline for washing wounds. The pressing component includes a piston plate 14 installed in the sterile liquid storage tank 13, and a spring 9 is installed on the piston plate 14.

[0034] The use process of the utility model is:

[0035] 1 After cleaning the wound surface, cover the wound surface with vsd dressing 6 and apply a film, and the device is leak-proof; 13 Add sterile saline to the sterile liquid storage tank, compress the spring 9 and the piston plate 14, so that the liquid is under pressure, which is convenient for supplying water to the vsd dressing 6; 2 Turn on the vacuum pump 1 switch, adjust the pressure adjustment knob, adjust the negative pressure, and generate negative pressure in the pipeline. The saline 13 enters the drainage tube 5 through the one-way valve 8, and then enters the side of the vsd dressing 6 to rinse the wound. The waste liquid enters the sewage tank 12 through the water inlet pipe 15 and the one-way valve 18. The waste liquid remains in the sewage tank, and the air in the tank enters the hose 10 and the one-way valve 17 through the floating air inlet into the drainage tube 16, and finally is discharged through the vacuum pump 1.

[0036] It should be noted that compared with the traditional closed negative pressure drainage device, the negative pressure generating device (vacuum pump), waste liquid tank, saline tank (bottle) and VSD dressing of the utility model are independent of each other and need to be connected by pipelines in the middle, which is inconvenient to move and has many pipelines, which are prone to accidental detachment; and the negative pressure generating device requires an external power supply. After our improvement, except for the VSD dressing located on the wound surface of the wounded, the rest of the system is integrated into a whole, which is convenient for movement; and except for the pipeline connected to the VSD dressing, the rest of the pipeline can be fixed on the device, which greatly reduces the risk of pipeline detachment and is more convenient to move; it comes with a rechargeable battery, which is more convenient to carry.

[0037] In the field, it is inevitable that the device will tip over. In previous designs, if the device tipped over, there was a risk that sewage would enter the vacuum pump, causing damage to the equipment, or waste liquid would flow back, causing wound contamination. We changed the air inlet to a floating state, so that no matter how the device was turned over, the opening was above the liquid level to prevent liquid from entering the vacuum pump; we designed three one-way valves to further prevent liquid from flowing back after the device tipped over.

[0038] It is obvious to those skilled in the art that the above-mentioned specific examples are only preferred schemes of the present invention. Therefore, the improvements and changes that may be made by those skilled in the art to certain parts of the present invention still reflect the principles of the present invention and achieve the purpose of the present invention, and all belong to the scope of protection of the present invention.
