Description

Technical Field

[0001] This utility model relates to the field of medical testing equipment technology, specifically to a medical wound irrigation machine. Background Technology

[0002] After trauma, the wound is exposed, and a crucial step before drug treatment is to perform professional debridement and irrigation. This is the first step in the treatment of open wounds and one of the most effective means of preventing wound infection. Its main purpose is to effectively remove dust, bacteria, and other contaminants from the wound through the irrigation process, achieving initial wound purification and creating a suitable sterile or low-bacterial environment for the subsequent wound healing process.

[0003] The effectiveness of wound cleaning largely depends on the following factors: the water pressure used, the direction of the water flow, the temperature of the water flow, the type of cleaning solution, and the amount of liquid used.

[0004] Currently, irrigation modes on the market are mainly divided into manual and automatic irrigation. Manual irrigation lacks stability in controlling water pressure, flow, and temperature, which can easily irritate the wound and may even cause secondary damage due to improper operation. Furthermore, this mode is time-consuming and labor-intensive, and the irrigation effect is difficult to guarantee. In contrast, automatic irrigation can more effectively control various irrigation parameters, thereby improving the safety and efficiency of irrigation and reducing patient discomfort and potential risks.

[0005] Chinese patent CN1919156B discloses a digital multi-functional cleaning machine that can select the water spray pattern according to the type of external injury and control the cleaning pressure, flow rate, time, and pulsation frequency. However, different water spray patterns require different spray guns, which indirectly increases the equipment cost, and it lacks a water heating function, which may irritate the wound.

[0006] Chinese patents CN205867194U and CN205867197U disclose a medical wound cleaning machine with water inlet pressure stabilization function and a medical wound cleaning machine with heating function, respectively. The water inlet pressure stabilization device mainly relies on an elastic flow restrictor to achieve this function. The elastic flow restrictor has limited adjustment capability, and the deformation is small when the water pressure is low, so the obstruction effect on water flow is not obvious. High water pressure will cause the elastic flow restrictor to undergo excessive deformation or even damage. Moreover, the elastic flow restrictor is prone to elastic fatigue and has poor durability. The medical wound cleaning machine with heating function has a single function.

[0007] In medical practice, medical staff need to use a device when rinsing wounds. The device needs to meet the needs of normal wound rinsing and also have significant advantages compared to manual rinsing. Utility Model Content

[0030] The present invention will be further described below with reference to the embodiments.

[0031] like Figure 1-2As shown, the medical wound irrigation machine of this utility model includes a housing 18, characterized in that it further includes a clean water module, an irrigation fluid module, a heating module, a control and display module, and an irrigation gun module; the control and display module includes a controller 12 and a display 13, and the control and display module is integrated on the housing 18; the clean water module includes a flow valve 3 and a filter 4 arranged sequentially on a clean water pipeline 1; the clean water pipeline 1 is connected to the flow valve 3, and the flow valve needs to be manually controlled to adjust the clean water flow; the flow valve 3 is connected to the filter 4, which filters out impurities and other contaminants from the clean water to ensure the cleanliness of the clean water, and can stably control the clean water flow.

[0032] The flushing fluid module includes a flushing fluid pipeline 2 leading out from the flushing fluid bag 9 and a micro pump 10 installed on the flushing fluid pipeline 2; a valve 2 11 connected to the controller 12 is installed on the flushing fluid pipeline 2 after the micro pump 10; the micro pump 10 on the flushing fluid pipeline 2 is used to pump the flushing fluid out from the flushing fluid bag 9, and the valve 2 11 on the pipeline is controlled by the controller 12.

[0033] The heating module includes a flow sensor 6, a honeycomb heater 7, and a temperature sensor 8, which are sequentially arranged along the clean water pipeline 1 after the filter 4. The honeycomb heater 7 is connected to the controller 12. A valve 5 connected to the controller 12 is arranged between the filter 4 and the flow sensor 6. The flow sensor 6 and the temperature sensor 8 are respectively arranged before and after the honeycomb heater 7, and both the valve 5 and the honeycomb heater 7 are connected to and controlled by the controller 12. The honeycomb heater 7 is an instant heater with an extended water channel, which can regulate the temperature of the clean water. It heats up quickly and the heating temperature is stable, ensuring that there is no temperature stimulation when rinsing the wound. The flow sensor 6 and the temperature sensor 8 detect the flow rate and temperature of the clean water, respectively, to see if they are the required flow rate and temperature.

[0034] like Figure 2 As shown, the flushing gun module includes a flushing gun 14; the clean water pipeline 1 after the temperature sensor 8 and the rear end of the flushing liquid pipeline 2 are directly connected to the flushing gun 14.

[0035] like Figure 3 As shown, the rinsing gun 14 is equipped with a water transfer connector 141, a water nozzle connecting plate 142, a switching turntable 143, and a nozzle cover 145. The rear ends of the clean water pipe 1 and the rinsing liquid pipe 2 are respectively connected to the clean water connector 1411 and the rinsing liquid connector 1412 on the water transfer connector 141 inside the rinsing gun 14. The water transfer connector 141 serves as a transfer connection to prevent the pipe from being directly connected to the water nozzle connecting plate 142 in a loose manner, which could lead to water leakage.

[0036] The other side of the clean water connector 1411 is connected to the rear end of the clean water interface 1421 on the water nozzle connecting plate 142 via a hose. The other side of the flushing fluid connector 1412 is connected to the rear end of the flushing fluid interface 1422 on the water nozzle connecting plate 142 via a hose. The water nozzle connecting plate 142 is coaxially fixedly connected to the nozzle outer cover 145, and a rotatable switching turntable 143 is coaxially arranged between the water nozzle connecting plate 142 and the nozzle outer cover 145. The switching turntable 143 is provided with four sets of nozzles 1433 of different diameters, and the nozzles 1433 include clean water nozzles and flushing fluid nozzles. The washing liquid nozzles are arranged in pairs, with the larger outer nozzle being the clean water nozzle and the smaller inner nozzle being the flushing liquid nozzle. Each set of nozzles 1433 is respectively engaged with the clean water interface 1421 and the flushing liquid interface 1422 on the water nozzle connecting plate 142. The water nozzle connecting plate 142 is tightly connected to the switching turntable 143, and the clean water interface 1421 and the flushing liquid interface 1422 are tightly engaged with the nozzles 1433. The clean water interface 1421 and the flushing liquid interface 1422 are also provided with grooves on the outside and fitted with anti-leakage rubber strips. This structural design can prevent leakage when the switching turntable 143 rotates.

[0037] The nozzle 1433 is coaxially connected to the outlet on the nozzle cover 145; the switching turntable 143 is provided with four gear ball head holes 1431 corresponding to the nozzle 1433, and a gear ball head 144 is installed in the gear ball head hole 1431; by rotating the switching turntable 143, one of the gear ball heads 144 falls into the corresponding positioning hole on the water nozzle connecting plate 142 for gear adjustment, thereby realizing the control of the flushing flow rate.

[0038] In this embodiment, there are 4 groups of nozzles 1433. The diameter of the clean water nozzles in groups 1 to 3 gradually decreases. The clean water nozzle in group 4 is provided with an atomizing nozzle 1432. When the switch dial 143 is rotated to adjust the gear, gears 1 to 3 correspond to jet-like water flow, and gear 4 corresponds to mist-like water flow.

[0039] The chassis 18 also integrates a scanning and printing module, which includes a barcode scanning module 19 and a printing module 20. The scanning module 19 scans the barcode on the irrigation fluid bag 9, and the printing module 20 generates a printed receipt for the patient to sign. The control and display module controls the temperature adjustment of the heater, the switching on and off of the clean water and irrigation fluid, the machine's on / off status, the scanning of the irrigation fluid bag, and the generation of the printed receipt. The display screen shows the current water temperature and its preset value, the current water flow rate, the equipment's rinsing time, and the cycle of automatic rinsing.

[0040] The flushing gun module includes a hanging ring 15 on the outer wall of the housing 18 and a movable flushing gun bracket 16. The flushing gun hanging ring 15 on the side of the housing 18 is used to place the flushing gun 14 to prevent it from being placed randomly. The flushing gun bracket 16 can be changed shape at will to support the flushing gun 14, making it easy to use and freeing up the hands of medical staff.

[0041] The chassis 18 is connected to a power source, which can be a fixed power source or a portable power source.

[0042] like Figure 2 and Figure 4 As shown, the clean water pipe 1 and the flushing liquid pipe 2 connected to the flushing gun 14 are arranged in the hose 17, making the entire equipment structure more regular.

[0043] like Figure 4 As shown, the flushing gun 14 includes a gun housing 146, which is connected to the nozzle cover 145 via a switching dial 143. The positions where the gun housing 146 connects to the switching dial 143 are marked with corresponding gear numbers. The nozzles on the switching dial 143 are adjusted to correspond to the clean water outlet 1451 and the flushing fluid outlet 1452 on the nozzle cover 145, allowing clean water and flushing fluid to be sprayed from the flushing gun 14.

[0044] In use, the flow rate is adjusted via the flow valve 3. The applicable flow rate range for the flushing gun in this embodiment is 1.4L / min to 2.4L / min. This invention has automatic and manual modes. The controller 12 has buttons for "Automatic," "Water," "Heating," "Liquid / On / Off," "Cooling," "Scan," and "Print." In automatic mode, place the flushing gun 14 on the flushing gun holder 16, aim it at the wound to be flushed, press the "Scan" button on the controller 12, align the barcode of the flushing fluid bag 9 with the scanning module 19, and after successful recognition, press the "Automatic" button to enter the automatic flushing mode. The automatic flushing program will run and then stop. In manual mode, hold the flushing gun 14 and aim it at the wound to be flushed. Press the "Water" button on the controller 12 to turn on the water, and press it again to turn off the water. Press the "Liquid" button on the controller 12 to turn on the flushing fluid, and press it again to turn off the flushing fluid. The required temperature, flushing time, and flushing pressure can be manually controlled and adjusted. The flushing flow rate is adjusted by rotating the dial 143. Levels 1 to 3 produce a jet-like water flow, with progressively smaller nozzles resulting in a finer water flow, increased pressure, and faster flow rate. Level 4 produces a mist-like water flow. After flushing, the flushing gun 14 is hung on the hanging ring 15. The flushing gun holder 16 features a twistable design, its shape adaptable to the use of the flushing gun 14, preventing discomfort for medical personnel holding the flushing gun for extended periods. The hanging ring 15 on the outside of the casing is used to store the flushing gun 14, preventing damage or loss due to careless placement. The controller 12 of this invention can also monitor and automatically adjust the inlet and outlet water temperatures and flow rates, further stabilizing the water temperature and flow rate.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
