[0020] Compared with the prior art, the technical solution of this utility model embodiment has the following advantages:

[0021] This utility model provides an eye irrigation device, including: a liquid supply pipe, including an outlet and an inlet; an eyewash nozzle, the eyewash nozzle being connected to the outlet of the liquid supply pipe; and a heat insulation tube disposed inside the liquid supply pipe, the first end and the second end of the heat insulation tube being sealed to the inner wall of the liquid supply pipe, so that the liquid entering the liquid supply pipe passes through the heat insulation tube and then enters the eyewash nozzle through the outlet. In this embodiment, the heat-insulating tube is disposed inside the liquid supply pipe, and the heat-insulating tube is sealed to the liquid supply pipe, so that all the liquid entering the liquid supply pipe passes through the heat-insulating tube before entering the eyewash nozzle. This helps to reduce the loss of liquid heat and effectively suppress the problem of liquid temperature drop. Furthermore, the heat-insulating tube isolates the liquid in the liquid supply pipe from the external environment, thereby reducing the influence of the external environment on the liquid in the liquid supply pipe and effectively suppressing the problem of liquid temperature drop or rise. This, in turn, helps to improve the heat preservation effect of the eye irrigation device. Therefore, this embodiment of the invention is beneficial to achieve the application of liquid kept at a safe temperature range to the patient's eyes, thereby improving the comfort and safety of the eye irrigation device and effectively suppressing secondary harm to the patient caused by the eye irrigation device.

[0022] In the optional embodiment, the eye irrigation device satisfies one or more of the following: the eye irrigation device further includes a heat insulation jacket disposed between the liquid supply pipe and the heat insulation pipe; the hollow portion between the liquid supply pipe and the heat insulation pipe serves as the heat insulation jacket, and the heat insulation jacket is a gas-insulated jacket; the hollow portion between the liquid supply pipe and the heat insulation pipe serves as the heat insulation jacket, and the heat insulation jacket includes a nitrogen jacket or an argon jacket. The heat insulation jacket disposed between the liquid supply pipe and the heat insulation pipe allows the liquid entering the liquid supply pipe to pass through the heat insulation jacket before entering the eyewash nozzle, which helps to further reduce the influence of the external environment on the liquid in the liquid supply pipe, effectively suppresses the problem of liquid temperature decrease and increase, and improves the heat insulation effect of the eye irrigation device.

[0023] In an optional embodiment, the eye irrigation device further includes: a return pipe, the return pipe including a return port, the return port being connected to the supply pipe, and the connection point between the return port and the supply pipe being located between the outlet and inlet of the supply pipe; the eye irrigation device further includes: a temperature control switch, disposed on the supply pipe and located in the length region of the insulation tube, along the direction from the inlet to the outlet (i.e., along the liquid flow direction within the supply pipe), the temperature control switch being disposed downstream of the location of the return port, the temperature control switch being used to measure the liquid temperature in the insulation tube and control the on / off state of the insulation tube; when the liquid temperature is not within the required range, the temperature control switch is in a closed state to shut off the insulation tube; when the liquid temperature is within the required range, the temperature control switch is in an open state to open the insulation tube. In this embodiment, when the liquid temperature is not within the required range, the temperature control switch is in the off state to shut off the liquid supply pipeline. Liquid in the liquid supply pipeline with a temperature higher or lower than the safe temperature range flows back through the return pipeline, preventing liquid outside the safe temperature range from flowing into the eyewash nozzle. This effectively inhibits the eye irrigation device from causing secondary harm to the patient, thereby further improving the safety of the eye irrigation device.

[0024] Accordingly, this utility model embodiment provides a safety protection device, which includes the eye irrigation device described in this utility model embodiment. Since the eye irrigation device integrates a liquid supply pipe, an eye irrigation nozzle, and a heat preservation pipe, it is beneficial to improve the heat preservation effect of the eye irrigation device, and to make it possible to rinse the patient's eyes with liquid kept at a safe temperature range, thereby improving the comfort and safety of the eye irrigation device and effectively suppressing secondary damage to the patient caused by the eye irrigation device. Attached Figure Description

[0025] Figure 1This is a schematic diagram of the structure of the eye irrigation device according to an embodiment of the present invention. Detailed Implementation

[0026] As the background technology shows, ensuring that the water temperature of a shower and eyewash station is within a safe range has become an urgent problem to be solved.

[0027] To address the aforementioned technical problems, this utility model provides an eye irrigation device, comprising: a liquid supply pipe including an outlet and an inlet; an eyewash nozzle connected to the outlet of the liquid supply pipe; and a heat-insulating tube disposed inside the liquid supply pipe, wherein a first end and a second end of the heat-insulating tube are sealed to the inner wall of the liquid supply pipe, so that liquid entering the liquid supply pipe passes through the heat-insulating tube and then enters the eyewash nozzle through the outlet.

[0028] The heat-insulating tube is installed inside the liquid supply pipe and is sealed to the liquid supply pipe, so that all the liquid entering the liquid supply pipe passes through the heat-insulating tube before entering the eyewash nozzle. This helps reduce heat loss from the liquid and effectively prevents the liquid temperature from dropping. Furthermore, the heat-insulating tube isolates the liquid in the liquid supply pipe from the external environment, thereby reducing the impact of the external environment on the liquid in the liquid supply pipe and effectively preventing the liquid temperature from dropping or rising. This, in turn, improves the heat preservation effect of the eye irrigation device. Therefore, this embodiment of the invention facilitates the application of liquid kept at a safe temperature range to the patient's eyes, improving the comfort and safety of the eye irrigation device and effectively preventing secondary harm to the patient.

[0029] To make the above-mentioned objectives, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Figure 1 This is a schematic diagram of the structure of the eye irrigation device according to an embodiment of the present invention.

[0031] refer to Figure 1 The eye irrigation device provided in this embodiment includes: a liquid supply pipe 10, including an outlet 11 and an inlet 12; an eyewash nozzle 20, which is connected to the outlet 11 of the liquid supply pipe 10; and a heat-insulating tube 30, which is disposed inside the liquid supply pipe 10. The first end 31 and the second end 32 of the heat-insulating tube 30 are both sealed to the inner wall of the liquid supply pipe 10, so that the liquid entering the liquid supply pipe 10 passes through the heat-insulating tube 30 and then enters the eyewash nozzle 30 through the outlet 11.

[0032] The heat-insulating tube 30 is disposed inside the liquid supply pipe 10 and is sealed to the liquid supply pipe 10, so that all the liquid entering the liquid supply pipe 10 passes through the heat-insulating tube 30 before entering the eyewash nozzle 20. This helps reduce the loss of liquid heat. Furthermore, the heat-insulating tube 30 isolates the liquid in the liquid supply pipe 10 from the external environment, thereby reducing the impact of the external environment on the liquid in the liquid supply pipe 10 and effectively suppressing the problem of liquid temperature decrease or increase. This effectively suppresses the problem of liquid temperature decrease and improves the heat preservation effect of the eye irrigation device. Therefore, the eye irrigation device achieves the purpose of spraying liquid kept at a safe temperature range onto the patient's eyes, thereby improving the comfort and safety of the eye irrigation device and effectively preventing secondary harm to the patient.

[0033] The supply conduit 10 is used to supply liquid. Specifically, the supply conduit 10 is used to supply the rinsing liquid required for eye irrigation. As an example, the rinsing liquid is water. In other embodiments, the rinsing liquid may also be other liquids that are safe to use.

[0034] In this embodiment, the liquid supply pipe 10 includes the liquid outlet 11 and the liquid inlet 12. Liquid enters the liquid supply pipe 10 through the liquid inlet 12 and flows to the liquid outlet 11.

[0035] The insulation pipe 30 is used to keep the liquid in the liquid supply pipe 10 warm.

[0036] In this embodiment, the type of insulation pipe 30 includes: polyvinyl chloride pipe, polyethylene pipe or polypropylene pipe.

[0037] The insulation pipe 30 is made of polyvinyl chloride, polyethylene or polypropylene, which makes the insulation pipe 30 have a low thermal conductivity and high density. This helps to reduce the heat transfer efficiency of the insulation pipe 30 to the liquid in the liquid supply pipe 10, thereby effectively suppressing the problem of liquid temperature drop and improving the heat preservation effect of the eye irrigation device.

[0038] As an example, the insulation pipe 30 is made of polyvinyl chloride (PVC), which is inexpensive and helps reduce the cost of the eye irrigation device. In other embodiments, the insulation pipe may also be made of other polymeric organic materials.

[0039] In this embodiment, the eye irrigation device satisfies one or more of the following: the eye irrigation device further includes a heat insulation layer disposed between the liquid supply pipe and the heat insulation pipe.

[0040] The insulation layer 40 is disposed between the liquid supply pipe 10 and the insulation pipe 30, so that all the liquid entering the liquid supply pipe 10 passes through the insulation layer 40 before entering the eyewash nozzle 20. This helps to further reduce the influence of the external environment on the liquid in the liquid supply pipe 10, thereby effectively suppressing the problem of liquid temperature drop and rise, and thus improving the insulation effect of the eyewash device.

[0041] In one specific embodiment, the hollow portion between the liquid supply pipe 10 and the insulation pipe 30 serves as the insulation interlayer 40, and the insulation interlayer 40 is a gas insulation interlayer 41.

[0042] By using the hollow portion between the liquid supply pipe 10 and the insulation pipe 30 as the insulation interlayer 40, it is beneficial to reduce the complexity of obtaining the insulation interlayer 40.

[0043] In this embodiment, the thermal insulation interlayer 40 is a gas thermal insulation interlayer 41, and the gas used in the gas thermal insulation interlayer 41 includes nitrogen or argon. In other words, the thermal insulation interlayer 40 includes a nitrogen interlayer or an argon interlayer.

[0044] The gas used in the gas insulation jacket 41 has stable chemical properties and low thermal conductivity, which helps reduce the heat transfer efficiency of the external environment to the liquid in the supply pipe 10. In addition, since the first end 31 and the second end 32 of the insulation pipe 30 are both sealed to the inner wall of the supply pipe 10, the insulation jacket 40 is a closed space. Moreover, the gas used in the gas insulation jacket 41 has a higher density than air, which helps to form a static gas layer in the gas insulation jacket 41, thereby avoiding gas convection in the insulation jacket 40 and effectively suppressing heat loss caused by gas flow. In summary, the insulation jacket 40 helps to reduce the heat transfer of the external environment to the liquid in the supply pipe 10, thereby effectively suppressing the problem of liquid temperature drop or rise, and improving the heat preservation effect of the eye irrigation device. Moreover, the gas used in the gas insulation interlayer 41 has stable chemical properties, which isolates the insulation tube 30 from contact with oxygen and other chemical substances, thereby effectively inhibiting the oxidation of the insulation tube 30, which is beneficial to improving the service life of the insulation tube 30, and thus improving the reliability of the eye irrigation device.

[0045] As an example, the gas insulation interlayer 41 uses argon gas, which has the advantage of low cost. In other embodiments, the gas insulation interlayer may also use other inert gases; in other words, the gas insulation interlayer may be other types of gas interlayers.

[0046] In some other embodiments, the insulation interlayer may also be a material layer with a low thermal conductivity.

[0047] In other embodiments, the outer wall of the insulation pipe may also contact the inner wall of the liquid supply pipe, and correspondingly, the eye irrigation device may not include the insulation interlayer.

[0048] In this embodiment, when the hollow portion between the liquid supply pipe 10 and the insulation pipe 30 serves as the insulation interlayer 40, the eye irrigation device further includes a ball valve 42, which is disposed on the liquid supply pipe 10. The ball valve 42 is used to open or close the air passage between the insulation interlayer 40 and the external air source.

[0049] When the ball valve 42 is opened, the insulation jacket 40 is connected to the external air source, allowing gas to be transported, so that the external air source can supply gas to the insulation jacket 40. When the ball valve 42 is closed, the air passage between the insulation jacket 40 and the external air source is cut off, thereby preventing the external air source from continuing to supply gas to the insulation jacket 40 and suppressing gas leakage in the insulation jacket 40.

[0050] Specifically, the ball valve 42 is easy to operate, which helps to reduce the difficulty of supplying gas to the insulation jacket 40; in addition, the ball valve 42 has good sealing performance, which effectively reduces the probability of air leakage in the insulation jacket 40, thereby effectively suppressing the problem of reduced insulation effect of the insulation jacket 40 due to air leakage; moreover, the ball valve 42 has a long service life, and due to its structural characteristics, the ball valve 42 can meet the requirements of high-pressure gas use, which helps to improve the reliability of the ball valve 42.

[0051] In other embodiments, the eye irrigation device may also employ other types of valves to supply gas to the insulation interlayer.

[0052] In this embodiment, the external gas source is a gas supply device 43, and the ball valve 42 is used to connect with the gas supply device 43, so that the gas supply device 43 supplies gas to the insulation jacket 40 through the ball valve 42.

[0053] As an example, the eye irrigation device may include the air supply device 43 for supplying gas to the ball valve 42. For instance, the air supply device 43 may include a quick-connect air hose connector (not shown) that is connected to the ball valve 42.

[0054] As an example, the gas supply device 43 is a portable argon cylinder. When the insulation jacket 40 begins to be filled with gas, the ball valve 42 opens and connects to the quick-connect gas hose connector. The portable argon cylinder fills the insulation jacket 42 with gas (e.g., argon) via the ball valve 42 through the quick-connect gas hose connector. In other embodiments, the gas supply device may also be other equipment that holds other gases.

[0055] It should be noted that in some embodiments, the eye irrigation device may not include the air supply device, and the ball valve can be used to communicate with the air supply device. In other embodiments, the eye irrigation device may not include the ball valve, and the thermal insulation layer 40 is in a sealed state.

[0056] In this embodiment, the eye irrigation device further includes a return pipe 50, which includes a return port 51. The return port 51 is connected to the liquid supply pipe 10, and the connection position between the return port 51 and the liquid supply pipe 10 is located between the liquid outlet 11 and the liquid inlet 12 of the liquid supply pipe 10.

[0057] The return pipe 50 is used to return the liquid in the supply pipe 10.

[0058] In this embodiment, liquid outside the safe temperature range in the supply pipe 10 flows back out through the return pipe 50, preventing liquid outside the safe temperature range from flowing into the eyewash nozzle, effectively inhibiting secondary harm to the patient from the eyewash device, thereby improving the safety of the eyewash device.

[0059] The reflux port 51 is used to connect the reflux pipe 50 and the liquid supply pipe 10.

[0060] Specifically, the reflux port 51 is located between the outlet 11 and the inlet 12 of the liquid supply pipe 10. This allows any liquid outside the safe temperature range in the liquid supply pipe 10 to flow back through the reflux port 50 before flowing into the eyewash nozzle, thus preventing liquid outside the safe temperature range from flowing into the eyewash nozzle and effectively inhibiting secondary harm to the patient from the eyewash device. This improves the safety of the eyewash device.

[0061] In this embodiment, a pneumatic valve 52 is provided on the return pipe 50, and the pneumatic valve 52 is used to control the on / off state of the return pipe 50.

[0062] The pneumatic valve 52 has a fast response speed. When the liquid in the supply pipe 10 is not within the safe temperature range, it helps to reduce the response time of the pneumatic valve 52 to the opening command of the control device, so that the liquid in the supply pipe 10 that is not within the safe temperature range can be discharged in time through the return pipe 50, thereby helping to keep the liquid in the supply pipe 10 within the safe temperature range. In addition, the pneumatic valve 52 also has the advantages of high temperature resistance (e.g., able to withstand the high temperature environment in summer), low failure rate and convenient maintenance, which helps to improve the service life and reliability of the pneumatic valve 52.

[0063] In other embodiments, the return conduit may also employ other types of valves.

[0064] In this embodiment, the return pipe 50 further includes a discharge port 54, through which the flushing liquid inside the return pipe 50 is discharged.

[0065] In this embodiment, the eye irrigation device further includes: a liquid storage device 53, which is connected to the inlet 12 of the liquid supply pipe 10; and the outlet 54 of the return pipe 50 is connected to the liquid storage device 53.

[0066] The liquid storage device 53 is used to supply the flushing liquid to the liquid supply pipe 10, and also to store the flushing liquid that returns through the return pipe 50, so that the returned flushing liquid can be reused, thereby avoiding waste of the flushing liquid.

[0067] In other embodiments, the liquid storage device may not be connected to the inlet of the liquid supply pipe. For example, the liquid storage device may correspond one-to-one with the liquid supply pipe and the return pipe. In other embodiments, the outlet of the return pipe is not connected to the liquid storage device, but the flushing liquid inside the return pipe is discharged by other means.

[0068] In this embodiment, the eye irrigation device further includes a temperature control switch 13, which is disposed on the liquid supply pipe 10 and located in the length region where the heat preservation pipe 30 is located, along the direction from the liquid inlet to the liquid outlet (that is, along the liquid flow direction in the liquid supply pipe 10), and the temperature control switch 13 is disposed downstream of the location of the return port 51.

[0069] The temperature control switch 13 is used to measure the liquid temperature in the insulation tube 30 and control the on / off state of the insulation tube 30. When the liquid temperature is not within the required range, the temperature control switch is in the closed state to shut off the insulation tube. When the liquid temperature is within the required range, the temperature control switch is in the open state to open the insulation tube.

[0070] When the liquid temperature is not within the safe temperature range, the temperature control switch 13 is in the closed state to shut off the liquid supply pipe 10. This allows liquid in the liquid supply pipe 10 with a temperature higher or lower than the safe temperature range to flow back through the return pipe 50, preventing liquid outside the safe temperature range from flowing into the eyewash nozzle 20. This effectively inhibits the eye irrigation device from causing secondary harm to the patient, thereby improving the safety of the eye irrigation device.

[0071] It should be noted that the safe temperature range described in this embodiment is 15 degrees Celsius to 37 degrees Celsius. When the liquid temperature exceeds 37 degrees Celsius, the liquid will cause burns and reduce comfort when it is sprayed onto the patient's eyes through the eye irrigation device, resulting in secondary injury. When the liquid temperature is below 15 degrees Celsius, the liquid will cause adverse nerve reactions such as shivering when it is sprayed onto the patient's eyes through the eye irrigation device, making it impossible for the patient to maintain a relatively stable posture for rinsing their eyes, thereby reducing the rinsing effect of the eye irrigation device. Moreover, when the liquid temperature is below 15 degrees Celsius and the external ambient temperature is cold, the tube of the eye irrigation device may freeze at low temperature, affecting normal use.

[0072] As an example, the temperature control switch 13 integrates a temperature sensor (not shown) for measuring the liquid temperature in the insulation pipe 30. In other embodiments, the temperature control switch may also integrate other devices that can be used for temperature measurement.

[0073] Specifically, when the liquid temperature in the supply pipe 10 is not within the safe temperature range, the temperature control switch 13 is in the closed state, and the corresponding pneumatic valve 52 is opened to open the return pipe 50, so that the liquid in the supply pipe 10 flows back out through the return pipe 50; when the liquid temperature in the supply pipe 10 is within the safe temperature range, the temperature control switch 13 is in the open state, and the corresponding pneumatic valve 52 is closed to shut off the return pipe 50.

[0074] In this embodiment, the temperature control switch 13 is controlled by a control device (not shown in the figure).

[0075] Specifically, the control device is used to receive temperature measurement data from the temperature control switch 13 and control the on / off state of the temperature control switch 13 and the pneumatic valve 52; when the liquid temperature in the insulation pipe 30 is not within the required range, the control device closes the temperature control switch 30 and opens the pneumatic valve 52; when the liquid temperature in the insulation pipe 30 is not within the required range, the control device opens the temperature control switch 13 and closes the pneumatic valve 52.

[0076] As an example, the control device is a programmable logic controller (PLC). In other embodiments, the control device may also be other control equipment.

[0077] In some embodiments, the control device may be integrated into the eye irrigation device; in other embodiments, the control device may be independent of the eye irrigation device. In other embodiments, the temperature control switch may also autonomously control the on / off state of the insulation tube based on the measured liquid temperature.

[0078] In this embodiment, the eye irrigation device further includes an eyewash nozzle switch 14, which is disposed on the liquid supply pipe 10. Along the direction from the liquid inlet to the liquid outlet (that is, along the flow direction of the liquid in the liquid supply pipe 10), the eyewash nozzle switch 14 is disposed downstream of the location of the temperature control switch 13. The eyewash nozzle switch 14 is used to control the on / off state between the liquid supply pipe 10 and the eyewash nozzle 20.

[0079] The eyewash nozzle switch 14 is located downstream of the temperature control switch 13. When the liquid in the liquid supply pipe 10 is not within the safe temperature range, the temperature control switch 13 is in the closed state to shut off the liquid supply pipe 10, preventing liquid outside the safe temperature range from entering the eyewash nozzle 20 through the eyewash nozzle switch 14. This effectively inhibits the eye irrigation device from causing secondary harm to the patient, thereby improving the reliability of the eye irrigation device.

[0080] Furthermore, by placing the eyewash nozzle switch 14 downstream of the location of the temperature control switch 13, it is beneficial to avoid the possibility that the temperature control switch 13 will be unable to control the liquid in the insulation interlayer 40 when the eyewash nozzle switch 14 is closed.

[0081] In other embodiments, the eyewash nozzle switch may be located in other positions.

[0082] As an example, the eyewash nozzle switch 14 is a manual switch ball valve. The manual switch ball valve is simple to operate, saves time and effort, and helps to reduce the difficulty of using the eye irrigation device, thereby avoiding problems such as opening failure during use and effectively suppressing the problem of patients' injuries being aggravated due to the inability to rinse.

[0083] In other embodiments, the eyewash nozzle switch may also be other types of switches.

[0084] In this embodiment, the heat insulation pipe 30 is located inside the liquid supply pipe 10 between the liquid inlet 12 and the eyewash nozzle switch 14.

[0085] The liquid is stored inside the liquid supply pipe 10 between the liquid inlet 12 and the eyewash nozzle switch 14, so that the liquid inside the liquid supply pipe 10 is wrapped by the heat preservation pipe 30, which helps to improve the heat preservation effect of the liquid.

[0086] Furthermore, the portion of the liquid supply pipe 10 located between the liquid inlet 12 and the eyewash nozzle switch 14 is typically exposed to the outdoor environment, which has a greater impact on the liquid at this location. Therefore, placing the heat insulation pipe 30 inside the liquid supply pipe 10 between the liquid inlet 12 and the eyewash nozzle switch 14 can effectively maintain the temperature of the liquid.

[0087] In other embodiments, the insulation pipe 30 may also be disposed at other locations in the liquid supply pipe.

[0088] In this embodiment, the eyewash nozzle 20 is connected to the outlet 11 of the liquid supply pipe 10.

[0089] The eyewash nozzle 20 is used to spray the patient's eyes with the flushing liquid, which is within a safe temperature range, from the supply pipe 10.

[0090] In this embodiment, the eyewash nozzle 20 includes: a support pipe 21, which includes a first connecting port 211 and a second connecting port 212, the first connecting port 211 being connected to the liquid outlet 11; a hose 22, one end of which is connected to the second connecting port 212 of the support pipe 21; a liquid output pipe 23, which is connected to the other end of the hose 22; and a nozzle 24, which is connected to the end of the liquid output pipe 23 that is not connected to the hose 22.

[0091] The support pipe 21 is used to support the nozzle 24 and to connect the eyewash nozzle 20 to the liquid supply pipe 10.

[0092] The hose 22 is used to adjust the shower angle of the eyewash nozzle 20.

[0093] The flexible tube 22 can be extended and bent within a certain range, so that the liquid outlet angle of the liquid outlet pipe 23 can be adjusted accordingly within a certain range. This allows the patient to adjust the angle of the liquid outlet pipe 23 as needed by extending and bending the flexible tube 22 when performing eye irrigation, which helps to improve the versatility of the eye irrigation device.

[0094] In other embodiments, the eyewash nozzle may also employ other deformable devices for adjusting the shower angle.

[0095] In this embodiment, the eyewash nozzle 20 further includes: a telescopic module 25 disposed beside the flexible hose 22; the telescopic module 25 includes: a telescopic rod 26, one end of which is fixedly connected to the side wall of the liquid output pipe 23, and the other end of which is provided with a first through-hole 261; a support rod 27, one end of which is fixedly connected to the side wall of the support pipe 21, and the other end of which is provided with a second through-hole 271; and a fixed connecting device 28, which fixes the telescopic rod 26 and the support rod 27 through the first through-hole 261 and the second through-hole 271.

[0096] The telescopic module 25 is used to control the length of the hose 22, so that the hose 22 can be extended and bent within a certain range.

[0097] The telescopic rod 26 is used to control the bending angle and telescopic length of the hose 22, so that the liquid ejection angle of the eyewash nozzle 20 is controlled within a reasonable shower angle range.

[0098] It should be noted that the reasonable shower angle range described in this embodiment can be from 45 degrees to 50 degrees.

[0099] The support rod 27 is used to fix the telescopic module 25, so that the telescopic module 25 is fixedly connected to the eyewash nozzle 20, effectively suppressing the problem of accidental displacement of the safety module 25, which helps to improve the stability of the telescopic module 25, thereby making it easier to control the shower angle of the eyewash nozzle 20.

[0100] The fixed connection device 28 is used to fix the telescopic rod 26 and the support rod 27, so that the telescopic rod 26 avoids unexpected displacement in the angular direction while extending and retracting in length, effectively suppressing the hose 22 from bending beyond the reasonable shower angle range, thereby avoiding the problem of the eyewash nozzle 20 affecting the showering effect due to excessive or insufficient shower angle, which helps to improve the reliability of the eyewash device.

[0101] As an example, the fixing connection device 28 may include bolts and nuts.

[0102] In this embodiment, the eye irrigation device further includes an eye opening device 29, which is disposed on the side wall of the nozzle 24 and close to the end of the nozzle 24 where the liquid outlet is located.

[0103] The eye-opening device 29 is used to assist the patient in opening their eyes.

[0104] As an example, the eye-opening device 29 includes an eye-opener 292 and an eye-opener bolt 291, wherein the eye-opener 292 is fixed to the side wall of the nozzle 24 by the eye-opener bolt 291.

[0105] The eye-opening bolt 291 integrates and fixes the eye-opening device 29 with the eye-washing nozzle 20, which helps to improve the stability of the eye-opening device 29, avoids accidental displacement of the eye-opening device 29, and effectively suppresses the problem of secondary mechanical injury to the patient caused by the edge of the eye-opening device 29, thereby improving the safety of the eye irrigation device.

[0106] The eye opener 292 is used to open the patient's eyes, effectively suppressing the problem that the patient is unable to open their eyes due to nerve sensitivity or other reasons, which helps to improve the rinsing effect of the eye rinsing device.

[0107] Accordingly, this utility model embodiment also provides a safety protection device, which includes the eye irrigation device described in the foregoing embodiment.

[0108] Because this eye irrigation device integrates a liquid supply pipe, an eyewash nozzle, and a heat preservation tube, it is beneficial to improve the heat preservation effect of the eye irrigation device, and to ensure that the liquid kept at a safe temperature range is sprayed onto the patient's eyes. This is beneficial to improve the comfort and safety of the eye irrigation device, and effectively prevents the eye irrigation device from causing secondary harm to the patient.

[0109] In this embodiment, the safety protection equipment includes a shower device, which includes the eye rinsing device described in the foregoing embodiment.

[0110] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
