[0057] In order to make the technical problem solved by the present invention, the technical solution adopted and the technical effect achieved more clearly, the technical solution of the present invention is further explained below with reference to the accompanying drawings and through specific implementation methods.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0061] Embodiment 1

[0062] like Figure 1-Figure 5As shown, the present embodiment provides an integrated NO generating device 1000, which mainly includes a shell 1 and a cover body 2. Among them, a receiving chamber is provided in the shell 1, and a plurality of mutually isolated chambers are separated in the receiving chamber; the cover body 2 includes a flow path module 21 and a receiving chamber 20, the flow path module 21 is partially received in the receiving chamber 20, the cover body 2 covers the shell 1, and the receiving chamber 20 is detachably sealed to the top of the receiving chamber. The flow path module 21 includes an external interface unit 21', an internal interface unit and a pipeline unit, the pipeline unit is connected to the external interface unit 21' and the internal interface unit, the end of the internal interface unit away from the pipeline unit is connected to the chamber, and the end of the external interface unit 21' away from the pipeline unit is connected to the outside of the receiving chamber 20. Specifically, the end of the external interface unit 21' away from the pipeline unit can be recessed in the receiving chamber 20, or protrudes from the outside of the receiving chamber 20, so as to Figure 4 For example, the external interface unit 21 ′ of this embodiment protrudes from the outside of the accommodation chamber 20 .

[0063] Based on the above design, in this embodiment, the storage chamber is a hollow columnar structure with an open top. Preferably, the storage chamber is a hollow cylindrical structure. A fool-proof structure 10 is formed on the side of the storage chamber. Exemplarily, the fool-proof structure 10 is concave or convex. Figure 1-Figure 2 As shown, the present embodiment is preferably a concave foolproof structure 10. The setting of the foolproof structure 10 is conducive to the installation of the integrated NO generating device 1000 at the installation position of the host 2000, simplifies the assembly difficulty, improves the convenience of user use, improves the treatment efficiency, shortens the downtime of the NO generating device for maintenance, and ensures the treatment timeliness.

[0064] Optionally, the shape of the cover body 2 matches the shape of the top of the accommodating chamber, and the cover is closed on top of the accommodating chamber to seal the accommodating chamber. The accommodating chamber 20 is a hollow structure, and the shape of the accommodating chamber 20 matches the shape of the accommodating chamber. It is detachably connected to the top of the accommodating chamber by bolts and other structural parts, thereby forming a seal for the accommodating chamber.

[0065] Alternatively, if Figure 1-Figure 5 As shown, the multiple chambers in this embodiment can be chambers separated by partitions, or can be multiple independently detachable chambers installed. In this embodiment, the chambers include a liquid storage tank, a filter tank and a recovery tank 15, and the pipeline unit includes a liquid pipeline and a gas pipeline. The liquid pipeline is connected to the liquid storage tank and / or the recovery tank 15, and the gas pipeline is connected to the filter tank. Among them, the liquid storage tank, the filter tank and the recovery tank 15 can be set to one, two, three or other quantities, and the operator can flexibly set the number of liquid storage tanks, filter tanks and recovery tanks 15 according to actual needs.

[0066] Optionally, in this embodiment, two liquid storage tanks, two filtering tanks and one recovery tank 15 are provided. The two liquid storage tanks are named as liquid storage tank A11 and liquid storage tank B12, the two filtering tanks are named as filtering tank A13 and filtering tank B14, and one recovery tank 15.

[0067] Specifically, the liquid storage tank A11 is used to hold the reaction liquid A, such as a citric acid solution. The liquid storage tank B12 is used to hold the reaction liquid B, such as a sodium nitrite solution. The citric acid solution and the sodium nitrite solution can react to generate NO gas after mixing. In addition, the reaction liquid A can also be hydrochloric acid, sulfuric acid, acetic acid, oxalic acid, L-ascorbic acid, L-malic acid, or citric acid-hydrochloric acid buffer, citric acid-sodium citrate buffer, sodium citrate-hydrochloric acid buffer, glycine-hydrochloric acid buffer, disodium hydrogen phosphate-potassium dihydrogen phosphate buffer, phthalic acid-hydrochloric acid buffer, HEPES-hydrochloric acid buffer, etc., which can provide hydrogen ion solutions; reaction liquid B can be sodium nitrite or other nitrite solutions, etc., which can provide nitrite solutions. Of course, reaction liquid A and reaction liquid B can also be set to other chemical reagents, as long as they can produce NO gas, which will not be repeated here one by one.

[0068] Further, the filter chamber A13 is used to purify and reduce the gas product. For example, the filter chamber A13 is filled with NO2 treatment materials (VC particles, etc.) to reduce NO2 in the gas product to NO. The filter chamber B14 is used to absorb and reduce the gas product. For example, the filter chamber B14 is filled with NOx treatment materials (potassium permanganate, etc.) to absorb NO and NO2 in the gas product. In this embodiment, the design of the filter chamber and the corresponding pipeline allows the gas to flow from bottom to top, and the gas can pass through the filter material more fully, which can ensure a higher filtering and reduction efficiency.

[0069] Furthermore, the recovery bin 15 is used to hold the waste liquid after the reaction. A certain amount of treatment liquid is pre-installed in the recovery bin 15. Since the waste liquid entering the recovery bin 15 may not react fully, and since the recovery bin 15 is sealed, if the waste liquid continues to react in the recovery bin 15 to generate NO gas, it will cause the pressure in the bin to be too high, which will cause the liquid in the pipeline to flow back, or destroy the sealing structure of the bin, affecting the normal operation of the equipment. Therefore, by pre-installing a certain amount of treatment liquid in the recovery bin 15, the waste liquid will react with the treatment liquid after entering the recovery bin 15, thereby preventing the reaction liquid A and the reaction liquid B in the waste liquid from reacting with each other to generate gas.

[0070] Optionally, the treatment liquid can be set as a hydroxide ion source donor, that is, a substance that can provide hydroxide ions. More specifically, the treatment liquid can be calcium hydroxide (solid or solution), calcium oxide (solid), sodium hydroxide (solid or solution), etc.; the treatment liquid is preferably a calcium hydroxide solution, which can neutralize the hydrogen ions in the waste liquid entering the recovery bin 15, and the reaction will not produce gas, effectively avoiding the remaining hydrogen ions in the recovery bin 15 and nitrite ions to continue to react to generate gas and cause excessive pressure.

[0071] Optionally, the volume of the recovery bin 15 is greater than the volumes of the liquid storage bin A11 and the liquid storage bin B12. In this embodiment, the volume of the recovery bin 15 is at least equal to or greater than the sum of the volumes of the liquid storage bin A11 and the liquid storage bin B12, thereby ensuring that the recovery bin 15 can be sufficient to hold the waste liquid after the reaction and avoiding overflow of the waste liquid after the reaction.

[0072] like Figure 3-Figure 4 As shown, in this embodiment, the liquid pipeline includes a first liquid pipeline and a second liquid pipeline 212, and the first liquid pipeline is connected to the liquid storage tank. Further, when there are two or more liquid storage tanks, the first liquid pipeline also has a corresponding number, and its internal interface is respectively connected to a corresponding liquid storage tank. The second liquid pipeline 212 is connected to the recovery tank 15; the gas pipeline includes a first gas pipeline and a second gas pipeline 216, the first gas pipeline is connected to the filter tank, and the second gas pipeline 216 is connected to the purification component. Further, when there are two or more filter tanks, the first gas pipeline also has a corresponding number, and its internal interface is respectively connected to a corresponding filter tank.

[0073] Specifically, two first liquid pipelines are set, namely, the first liquid pipeline A210 and the first liquid pipeline B211, and their internal interfaces are connected to the liquid storage tank A11 and the liquid storage tank B12 respectively; three first gas pipelines are set, namely, the first gas pipeline A213, the first gas pipeline B214, and the first gas pipeline C215, the internal interface of the first gas pipeline A213 is connected to the air inlet of the filter tank A13, the internal interface of the first gas pipeline B214 is connected to the air outlet of the filter tank A13, and the internal interface of the first gas pipeline C215 is connected to the air inlet of the filter tank B14.

[0074] Exemplarily, when the fool-proof structure 10 of the accommodation chamber is a concave structure, the external interface unit 21' of the flow path module 21 protrudes downward from the cover body 2, and the external interface is arranged at a position corresponding to the concave structure of the accommodation chamber, thereby facilitating the subsequent maintenance and disassembly of the pipeline unit and improving work efficiency.

[0075] Preferably, in this embodiment, the external interface unit 21' includes a plurality of quick-plug connectors, and the internal interface unit includes a plurality of quick-plug connectors. In this way, the integrated NO generation module can be replaced by a doctor or patient through a simple plug-in installation at the user end; at the maintenance end, the maintenance engineer can open the receiving chamber to replace the liquid, replace / check the filter, etc., which is simple and convenient to operate.

[0076] Optionally, the air inlet of the filter bin A13 is arranged at the bottom of the filter bin A13, and the air outlet is arranged at the top.

[0077] Optionally, the air inlet of the filter bin B14 is arranged at the bottom of the filter bin B14, the air outlet is arranged at the top, and the air outlet is connected to the environment.

[0078] like Figure 4 As shown, in this embodiment, the pipeline unit includes a balancing pipeline, one end of the balancing pipeline is connected to the liquid storage tank, and the other end of the balancing pipeline is connected to the recovery tank 15. The balancing pipeline is configured to balance the air pressure in the liquid storage tank.

[0079] Specifically, two balancing pipelines are provided, namely, balancing pipeline A217 and balancing pipeline B218. One interface of balancing pipeline A217 is connected to liquid storage tank A11, and the other interface is connected to recovery tank 15; one interface of balancing pipeline B218 is connected to liquid storage tank B12, and the other interface is connected to recovery tank 15. The setting of balancing pipeline is conducive to balancing air pressure. Since the above-mentioned chambers are all sealed, liquid needs to be extracted or input during use. In order to ensure the normal transportation of liquid, balancing pipelines are provided. For example, when waste liquid is input into the recovery tank 15, the excess gas occupied by the waste liquid space will be replenished to the corresponding liquid storage tank.

[0080] like Figure 1-Figure 4 As shown, in this embodiment, the integrated NO generating device 1000 further includes a baffle 23, which is disposed on the side wall of the external interface unit 21' protruding from the accommodating chamber 20, and the baffle 23 is detachably connected to the side wall of the accommodating chamber 20, thereby facilitating inspection and maintenance of the various pipelines in the accommodating chamber 20.

[0081] like Figure 1-Figure 4 As shown, in this embodiment, a guard plate 24 is further provided at the top of the cover body 2, and the guard plate 24 is connected to the cover body 2 by mounting components such as bolts, so as to protect the cover body 2 and enhance the mechanical strength of the cover body 2.

[0082] Compared with the prior art, the integrated NO generating device 1000 provided in this embodiment integrates the consumable structure that needs to be frequently replaced and maintained, which is convenient for unified replacement and maintenance of the consumables in the NO generating device, saving time and effort, greatly shortening the downtime of the device for maintenance, and ensuring the timeliness of treatment. In addition, the functional areas of the integrated NO generating device 1000 are reasonably laid out, the lines of each pipeline are clear, the volume is small, the space utilization rate is high, and the integration is high, which is conducive to the miniaturization and portability of the device, and the transportation requirements are not high, and there is no need to limit harsh transportation and use conditions. It is easy to transport and has a wide range of applicable scenarios. At the same time, the integrated NO generating device 1000 integrates the three functions of liquid storage, waste liquid recovery, and gas treatment, which can ensure that within an effective NO release cycle, there will be no gas treatment failure, waste liquid storage is full, and the situation that requires maintenance suspension will not occur, thereby improving the timeliness of treatment.

[0083] like Figure 6-Figure 9 As shown, this embodiment further provides a NO generating system, which includes a host 2000 and the above-mentioned integrated NO generating device 1000. The host 2000 is provided with a mounting position, and the integrated NO generating device 1000 is detachably mounted at the mounting position.

[0084] Specifically, the host 2000 is also provided with driving components necessary for liquid and gas transmission, such as pumps and valves (not shown in the figure), etc., which will not be described in detail here. Preferably, a quick-plug interface compatible with the external interface unit 21' is provided at the installation position to improve the efficiency of user assembly and use, save time and effort, shorten the downtime of the NO generating device for maintenance, and ensure the effectiveness of treatment.

[0085] like Figure 8 As shown, in this embodiment, the host 2000 includes a reaction chamber 3000, and the reaction chamber 3000 is connected to the first liquid pipeline, the second liquid pipeline 212, the first gas pipeline and the second gas pipeline 216 in the pipeline unit.

[0086] Further, the reaction chamber 3000 includes a liquid inlet, a liquid outlet, a gas inlet and a gas outlet, the liquid inlet is connected to the first liquid pipeline, the gas inlet is connected to the second gas pipeline 216, the liquid outlet is connected to the second liquid pipeline 212, and the gas outlet is connected to the first gas pipeline. The reaction chamber 3000 is connected to the downstream of the first liquid pipeline of the integrated NO generation module, and the reaction chamber 3000 is used to collect the reaction liquid in the liquid storage tank A11 and the liquid storage tank B12, and the two reaction liquids react in the reaction chamber 3000 to generate NO gas.

[0087] Furthermore, the reaction chamber 3000 is configured as a gas-liquid separator, and the reaction liquid A and the reaction liquid B enter the liquid path of the gas-liquid separator and mix to generate NO gas, which is then diffused to the gas path of the gas-liquid separator, and driven by the carrier gas transported in the second gas pipeline 216, the NO gas is output from the gas path outlet. Optionally, the carrier gas can be ambient gas or nitrogen. If the carrier gas is nitrogen, a nitrogen source needs to be connected to the gas inlet end of the second gas pipeline 216.

[0088] like Fig. 9 As shown, in this embodiment, the host 2000 further includes an output control module 4000 and a treatment room 5000, the output control module 4000 is connected to the first gas pipeline in the pipeline unit, the treatment room 5000 is connected to the downstream of the output control module 4000, and the treatment room 5000 is configured to accommodate the wound surface of the patient. The control module is used to control the amount of NO gas output to the outside.

[0089] For example, in this embodiment, the output control module 4000 can be set as a three-way valve or a solenoid valve. The structure of the treatment room 5000 in this embodiment can refer to the CN115770187A patent document, and the detailed structure of the treatment room 5000 is not repeated in this embodiment.

[0090] Furthermore, when the output control module 4000 is set as a three-way valve, one way of the output control module 4000 is connected to the first gas pipeline B214, one way is connected to the treatment room 5000, and one way is connected to the first gas pipeline C215.

[0091] In addition, the treatment room 5000 can also be directly connected to the first gas pipeline C215, so that the waste gas generated in the treatment room 5000 can enter the filter chamber B14 through the first gas pipeline C215 for treatment and then be discharged into the environment.

[0092] like Figure 1 As shown, in this embodiment, the NO generation system includes a recording module 6000, which is configured to record the consumption and remaining amount of the liquid in the chamber and the operating state of the NO generation system. The operating state of the system includes parameters such as temperature, humidity, concentration, and flow rate. Of course, the recording module 6000 can also record the identification number corresponding to the integrated NO generation device 1000, so as to perform information management and maintenance on the integrated NO generation device 1000.

[0093] Further, the recording module 6000 includes a chip and a reader, and the chip is connected to the reader by signal.
