Description

Technical Field

[0001] The present invention relates to the field of field medical equipment, and in particular to a portable emergency wound disinfection device. Background Art

[0002] Modern off-roading is extremely vulnerable to injury. Although improvements in personal protective equipment, improved field medical systems, and the systematic use of antimicrobial agents have significantly improved survival rates, survivors remain exposed to a variety of potentially fatal infections. Multiple limb injuries, infections with drug-resistant bacteria, and invasive fungal infections still contribute to wound infection rates as high as 27%, making it the second leading cause of death after hemorrhagic shock and multiple organ failure. Therefore, disinfection of the wound at the scene is a key first aid measure. By promptly removing contamination and inhibiting pathogen proliferation, it can effectively reduce the risk of infection, stabilize the patient's vital signs, and create favorable conditions for subsequent definitive treatment. Flushing the wound with copious amounts of water and normal saline is essential for wound disinfection, and the amount of irrigation depends on the degree of wound contamination. Regarding the selection of irrigation solutions, low-concentration detergents (such as bicarbonate solutions) are recommended for wound cavities to avoid tissue damage caused by high-concentration solutions. Regarding the choice of disinfectant, carbolic acid solutions (phenols) are commonly used for surface disinfection. In cases of severe contamination, the entire wound should be covered. Hypochlorous acid and iodine solutions are also commonly used for skin and instrument disinfection. However, the wounded personnel in the field have limited load capacity, and disinfectants such as saline and iodine tincture need to be carried in advance, which takes up load and is prone to leakage. Sodium hypochlorite disinfectant is not stable enough, is easily affected by temperature and humidity, and has a short shelf life (usually ≤ 1 year), so the inventory needs to be updated frequently.

[0003] In terms of disinfection equipment, pre-vacuum ozone sterilizers are already available in China. These utilize pre-vacuum cycle technology to achieve efficient, broad-spectrum sterilization, using the strong oxidizing properties of ozone to kill bacterial spores, viruses, and fungi. Overseas, the DECON / PAK disinfection system offers adjustable disinfectant concentrations (0.1%-0.5%) and rapidly disinfects personnel and equipment through spray nozzles, achieving a flow rate of up to 45 liters per minute, making it suitable for field emergency response.

[0004] However, the above two devices rely on external water sources or power sources, require additional equipment to be carried, cannot be used independently in the wild, and do not meet the lightweight requirements.

[0005] In summary, while existing on-site disinfection technologies for casualties have reached consensus on the basic process, they still face multiple practical challenges in the field. On the one hand, the burden of carrying liquid disinfectants and the risk of failure exacerbate the shortage of medical resources. On the other hand, disinfection devices are highly dependent on external sources and cannot operate independently without logistical support. Existing disinfection technologies face a significant contradiction between lightweight and portability. Therefore, the current technology system urgently needs to break through the limitations of a single function and develop an integrated, highly stable, lightweight and portable disinfection device to reduce the risk of infection and improve the quality of life of casualties.

However, for those skilled in the art, these embodiments are only examples, and the general principles defined herein can be applied to other embodiments and application scenarios without departing from the spirit and scope of the present invention.

[0045] According to an exemplary embodiment of the present invention: Figure 1-12 As shown, a portable emergency wound disinfection device includes: a bottle body 10, a first connecting member 30, a second connecting member 40, a bottle cap 20, a spray head assembly 50, and a sealing box 62.

[0046] like Figure 7As shown in FIG8 , a first connector 11 is formed on the bottle body 10 ; the first connector 30 includes a first partition 33 , a first connecting end 31 , and a second connecting end 32 , and the first partition 33 is located between the first connecting end 31 and the second connecting end 32 .

[0047] like Figure 9 As shown, the second connecting member 40 includes a second partition 43, a third connecting end 41, and a fourth connecting end 42. The second partition 43 is located between the third connecting end 41 and the fourth connecting end 42. An opening is formed on the second partition 43, and the nozzle assembly 50 is detachably connected to the second partition 43 through the opening.

[0048] like Figure 10 As shown, a second connector 21 is formed on the bottle cap 20 .

[0049] like Figure 1 As shown, the first connector 11 can be detachably connected to the first connection end 31 , the third connection end 41 , and the second connector 21 ; the second connector 21 can be detachably connected to the second connection end 32 and the fourth connection end 42 .

[0050] like Figure 11 As shown in FIG12 , the sealing box 62 is used to place disinfectants and is fixedly connected to the first connecting member 30 or the second connecting member 40 . The sealing box 62 is fixed on the second partition 43 .

[0051] like Figure 11 As shown in FIG12 , the nozzle assembly further includes a suction pipe 61. The second partition plate 43 is further provided with a plurality of first stoppers 63 for accommodating the suction pipe 61. The second partition plate 43 is further provided with two second stoppers 64 for accommodating the disassembled pressing cap 53 or the disassembled nozzle assembly.

[0052] In the first usage state of the present invention, when used as an ordinary water bottle, only the bottle body 10 and the bottle cap 20 can be carried, and the first connector 11 and the second connector 21 are used in conjunction with each other to use it as an ordinary water bottle.

[0053] The second use of the present invention is as a portable emergency wound disinfection device. The bottle body 10 is connected to the first connector 30, which is connected to the second connector 40, which is connected to the bottle cap 20. The bottle body 10 contains drinkable purified water. When disinfection is required, the bottle body 10 is separated from the first connector 30, and the bottle body 10 is used in conjunction with the second connector 40. The disinfectant tablet in the sealed box 62 is dissolved in the water, and the disinfectant is evenly sprayed through the nozzle assembly 50 for disinfection. In a preferred embodiment, the bottle body 10 is transparent and has scale lines on it for determining the concentration of the disinfectant.

[0054] According to an exemplary embodiment of the present invention, the spray head assembly 50 of the present invention may adopt an existing spray head assembly 50 .

[0055] According to an exemplary embodiment of the present invention, the present invention further provides a spray head assembly 50, such as Figure 5 As shown in Figure 6, the nozzle assembly 50 includes a pressing head and a suction pipe 61. The pressing head includes a pressing cap 53 and a pressing column 52. The pressing cap 53 and the pressing column 52 are detachably connected.

[0056] According to a preferred embodiment of the present invention, when the second connector 21 is connected to the fourth connection end 42, the pressing cap 53 and the straw 61 can be located in the space enclosed between the bottle cap 20 and the second connector 40. Optionally, when the second connector 21 is connected to the fourth connection end 42, the pressing cap 53 is removed from the pressing post 52 and placed in the space defined by the second stopper 64.

[0057] like Figure 5 As shown in Figure 6, the nozzle assembly 50 includes a cylinder body 51, and a pressing plate 525 is connected to one end of the pressing column 52, and the pressing plate 525 can move relative to the cylinder body 51; a first flow channel 521 and a second flow channel 522 are formed on the pressing column 52, and the first flow channel 521 and the second flow channel 522 are connected through a connecting port; a plunger 523 and a second elastic member 524 are provided in the second flow channel 522, and one end of the second elastic member 524 is fixed to the bottom of the second flow channel 522, and the other end is fixed to the plunger 523; the plunger 523 can move between a first position and a second position, in the first position, the plunger 523 closes the connecting port, and in the second position, the plunger 523 opens the connecting port; one end of the second flow channel 522 is a closed end, and the other end is an open end.

[0058] like Figure 5 6, the pressing cap 53 is formed with a third flow channel 531 connected to the second flow channel 522, and a fourth flow channel 532 is also formed on the pressing cap 53. The fourth flow channel 532 is connected to the third flow channel 531, and the fourth flow channel 532 is connected to the nozzle 533.

[0059] The second partition 43 further includes a reset portion 54, which is disposed around the outer periphery of the pressing post 52. The second partition 43 has a surrounding portion surrounding the opening, forming a horizontal abutment portion and a vertical limit portion. One end of the first elastic member 55 abuts against the reset portion 54, and the other end abuts against the abutment portion.

[0060] like Figure 5 6, further comprising a valve body 60. The cylinder body 51 includes a first compression space, a second compression space, a valve channel 515, and an external port 516. The cross-section of the valve channel 515 is formed into a structure that is larger at the top and smaller at the bottom. The valve body 60 is placed inside the valve channel 515. The valve body 60 has a tapered structure that is larger at the top and smaller at the bottom. The external port 516 is used for sealing connection with the suction pipe 61.

[0061] like Figure 5 6, when the nozzle assembly 50 of the present invention is used, the external interface 516 is connected to the suction tube 61. When the pressing cap 53 is pressed downward, the pressing cap 53 drives the pressing column 52 to move downward together, so that the pressure plate 525 moves downward, thereby squeezing the first space 513 and the second space 514. Under the action of pressure, the valve body 60 seals the external interface 516 below. As the pressure increases, the plunger 523 overcomes the elastic force of the second elastic member 524, thereby connecting the first flow channel 521 with the second flow channel 522. Under the action of strong pressure, the liquid is quickly ejected through the second flow channel 522, the first flow channel 521, the third flow channel 531, the fourth flow channel 532, and the nozzle 533.

[0062] Thereafter, under the action of the first elastic member 55, the reset portion 54 drives the pressing post 52 and the pressing cap 53 to reset. As the negative pressure in the first and second spaces 513, 514 is applied, the valve body 60 opens upward under the negative pressure, allowing the liquid in the bottle body 10 to enter the first and second spaces 513, 514. Thereafter, the bottle can be pressed again for recycling.

[0063] According to an exemplary embodiment of the present invention, Figure 6 As shown, the valve body 60 is a conical structure with a larger upper portion and a smaller lower portion. Obviously, other existing one-way valve structures can replace the above-mentioned valve body 60 structure, and all are within the scope of protection of the present invention. Preferably, a valve body 60 retaining structure can also be included, such as a blocking portion provided at the upper portion of the valve channel 515 to prevent the valve body 60 from detaching from the valve channel 515. Schematically, an annular plate (not shown) can be provided at the upper end of the valve channel 515, such as a detachable annular plate, or other forms of baffles can be provided at the upper end of the annular channel, as long as they can block the valve body 60, thereby keeping the valve body 60 in the valve channel 515.

[0064] According to an exemplary embodiment of the present invention, Figure 6 As shown, preferably, the plunger 523 has a predetermined length, so that the second elastic member 524 will not connect the first flow channel 521 with the space where the first elastic member 55 is located under the action of negative pressure.

[0065] like Figure 5 As shown, a guide block 534 is formed at the bottom of the pressing cap 53, and a guide groove 526 is formed at the top of the pressing post 52. The cooperation between the guide block 534 and the guide groove 526 ensures that the second flow channel 522 and the third flow channel 531 are connected when the pressing cap 53 and the pressing post 52 are fixed. The pressing cap 53 is also provided with a second locking ring 535, which cooperates with the locking groove 527 on the pressing post 52 to detachably fix the two together.

[0066] like Figure 1-12 As shown, a support ring 512 is formed on the top of the cylinder body 51, and the support ring 512 can be hung around the opening. A first locking ring 511 is formed on the side of the cylinder body 51, and an annular groove 44 that can cooperate with the first locking ring 511 is formed on the inner circumference of the opening.

[0067] When using the portable emergency wound disinfection device of the present invention, in daily use, only the bottle body 10 and the bottle cap 20 can be carried and used as a normal water cup. When used outdoors, the present invention can carry the bottle body 10, the first connecting member 30, the second connecting member 40, and the bottle cap 20 at the same time and fix them together in order.

[0068] The optional device of the present invention comprises a cylindrical drinking cup with a capacity scale (100ml-1000ml). The schematically illustrated sealed box 62 comprises two compartments. The first compartment stores compressed sodium chloride tablets, each weighing 4.5g, which can be dissolved in water to prepare 500ml of 0.9% saline solution. The second compartment stores chlorhexidine acetate tablets, each weighing 0.25g, which can be dissolved in water to prepare 500ml of disinfectant (0.05% concentration).

[0069] According to an exemplary embodiment of the present invention, during drug dissolution, field personnel open the lid, remove a sodium chloride tablet or a chlorhexidine gluconate tablet, and place it into the cup. Concentration control: After the sodium chloride tablet dissolves, isotonic saline is formed. After the chlorhexidine acetate tablet dissolves, the concentration is precisely controlled using the scale on the cup body: low concentration mode: add one chlorhexidine acetate tablet to 500ml of saline (concentration 0.05%); high concentration mode: add two chlorhexidine acetate tablets to 500ml of saline (concentration 0.1%). Suitable for severely contaminated wounds.

[0070] During use, the spray head assembly 50 is connected to the detachable silicone hose on the bottle cap 20 to spray the prepared disinfectant in a mist. Preferably, the spray head assembly 50 includes: ① a wide-angle fan-shaped nozzle 533 (covering an area ≥ 30cm×30cm); ② a silicone hose made of food-grade PP that covers the entire bottle and can extract liquid from the bottom.

[0071] It should be noted that although the present invention illustrates the structure of the nozzle assembly 50, which is only a preferred embodiment of the present invention, the present invention can also be implemented using an existing nozzle structure, which only needs to be fixed to the second partition plate 43 through the opening, and will not be described in detail here.

[0072] Compared with the prior art, the portable wound disinfection device of the present invention has the following significant advantages:

[0073] Functional integration breaks through the lightweight bottleneck with integrated design: the water cup, medicine box, and nozzle assembly 50 are integrated into the daily equipment (water cup) of field personnel. The space required is small, and no additional equipment is required. The weight carried by field personnel is reduced, which is significantly lighter than existing disinfection devices, and completely solves the problem of redundant field equipment.

[0074] Modular assembly and disassembly: Independent tablet compartment design avoids cross contamination.

[0075] Disinfection efficiency is significantly improved, and precise ratio control is achieved: through the predetermined dosage design of solid tablets (sodium chloride tablets 4.5g / tablet, chlorhexidine tablets 0.25g / tablet), combined with the visual adjustment of the cup body scale, precise preparation of normal saline (0.9%) and disinfectant (0.05%-0.1%) is achieved, which is better than the traditional manual estimation method; pressurized spray reduces liquid consumption.

[0076] Environmental adaptability and logistics support are optimized, and solid tablets are stable: sodium chloride tablets and chlorhexidine tablets are packaged in moisture-proof and oxygen-barrier packaging, have a long shelf life at room temperature, do not require cold chain storage, and reduce inventory update frequency compared to liquid sodium hypochlorite reagents (shelf life ≤ 1 year).

[0077] Improved operational efficiency and ergonomics, and a quick response mechanism: The entire process from tablet dissolution to spray disinfection takes a short time, meeting the needs of the golden first aid window in the wild.

[0078] Nozzle 533 is suitable for large wounds; the design of Nozzle 533 avoids accidental contamination and provides relatively sterile conditions.

[0079] When the present invention is used specifically:

[0080] Step 1: Device initialization and kit loading

[0081] ①Structural inspection: Confirm that the outer layer of aviation aluminum of the water cup is not damaged and the inner liner is clean and free of foreign matter.

[0082] ② Medicine box installation: Press the buckle at the bottom of the water cup to pull out the divided medicine box. The medicine box is divided into two compartments: the left compartment: stores sodium chloride tablets (4.5g each, a total of 10 tablets); the right compartment: stores chlorhexidine acetate tablets (0.25g each, a total of 20 tablets).

[0083] ③Sealing guarantee: ensure that the tablets do not shake or leak.

[0084] Step 2: Dissolution and proportioning operations

[0085] ① Medication selection: Select tablets according to the degree of wound contamination:

[0086] ② Mild contamination: Only normal saline rinse is required, and one sodium chloride tablet is placed in a cup of water;

[0087] ③ Moderate contamination: Take one chlorhexidine acetate tablet and add 500ml of water to prepare 0.05% disinfectant;

[0088] ④ Severe contamination: Take 2 chlorhexidine acetate tablets + 500ml of water to prepare 0.1% disinfectant.

[0089] ⑤ Fill water and dissolve: Pour clean water into the cup to the target scale line (such as 500ml, 1000ml).

[0090] Step 3: Pressurized spray disinfection

[0091] ① Nozzle 533 connection: Take out the silicone hose on the bottle cap 20 and connect it to the interface, and rotate the nozzle 533 to connect it to the cup mouth thread interface;

[0092] ② Spraying operation: Press the switch of nozzle 533, and the disinfectant will be sprayed out in a fan-shaped mist through nozzle 533 (covering an area ≥ 30 cm × 30 cm); keep the nozzle 533 15-20 cm away from the wound and move at a constant speed to ensure full coverage.

[0093] Step 4: Emergency Reserves and Maintenance

[0094] ① Storage of remaining tablets: Unused tablets can be stored in the medicine box;

[0095] ② Cleaning and disinfection: After use, disassemble the nozzle 533 and the hose, rinse with clean water, and then sterilize at high temperature.

[0096] The device of the present invention features integrated functions, breaking through the bottleneck of lightweight design. The integrated design integrates the water cup, medicine box, and nozzle assembly into the daily equipment (water cup) of field personnel. This requires minimal space and eliminates the need for additional equipment. This reduces the weight of field personnel carrying the device, significantly reducing weight compared to existing disinfection devices and completely resolving the issue of redundant field equipment. The design of the dedicated nozzle assembly of the present invention ensures sufficient pressure and uniform disinfection during spraying. The disinfectant does not come into contact with elastic components during spraying, thus avoiding infection risks such as rust on the elastic components.

[0097] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments and combinations of elements may be made without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
