[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] The following is for reference. Figures 1-2This invention describes a medical rinsing device according to an embodiment of the present invention.

[0027] like Figures 1-2 As shown, the medical flushing device according to an embodiment of the present invention includes: a liquid pump controller 10, a heater 13, a pressure measuring element 16, a first pipeline 21, a second pipeline 22, and a temperature sensor 24.

[0028] The liquid pump controller 10 includes a liquid pump and a pressure sensor 12. The liquid pump has a liquid pump roller 11. A heater 13, a first pipeline 21, a pressure sensor 16, and a second pipeline 22 are connected in sequence to form a liquid supply path 20. The heater 13 is adapted to be connected to a liquid source and can be connected to the liquid pump controller 10. A portion of the first pipeline 21 can be wound around the liquid pump roller 11. The pressure sensor 16 can be located on the pressure sensor 12 so that the liquid pump controller 10 can obtain the hydraulic pressure in the liquid supply path 20. The probe end 241 of the temperature sensor 24 is used to detect the liquid temperature in the liquid supply path 20 and can be connected to the liquid pump controller 10.

[0029] As some embodiments of this application, the medical irrigation device proposed in this application can be applied in medical surgery. The liquid in the liquid source can be, but is not limited to, the irrigation fluid used in surgery. This application will use the irrigation fluid used in medical surgery as an example for illustration.

[0030] The liquid pump controller 10 includes a liquid pump and a pressure sensor 12. The liquid pump has a liquid pump roller 11. The liquid pump can be configured as a peristaltic pump. The liquid pump roller 11 can drive liquid flow through the squeezing pipeline.

[0031] The heater 13, the first pipe 21, the pressure measuring element 16, and the second pipe 22 are connected in sequence to form a liquid supply flow path 20. The heater 13 is used to heat the flushing liquid to the required temperature. The first pipe 21 is connected between the heater 13 and the pressure measuring element 16 so that the flushing liquid can flow from the heater 13 through the first pipe 21 to the pressure measuring element 16. The pressure measuring element 16 has two opposite ends, one end of which is connected to the first pipe 21 and the other end of which is connected to the second pipe 22. The flushing liquid can flow through the pressure measuring element 16 and out of the second pipe 22.

[0032] As some embodiments of this application, the second conduit 22 is connected to an instrument connector 221, and the second conduit 22 can be connected to instruments on the operating table through the instrument connector 221 for rinsing.

[0033] The heater 13 can be connected to a liquid source. The connection between the heater 13 and the liquid source can be, but is not limited to, a pipeline connection. In some embodiments of this application, the heater 13 is connected to the liquid source through a third pipeline 23. The heater 13 can be electrically connected to the liquid pump controller 10. In some embodiments of this application, the heater 13 is connected to the liquid pump controller 10 through a wire connection.

[0034] A portion of the first conduit 21 can be arranged around the liquid pump roller 11. In other words, a portion of the first conduit 21 can be arranged around the liquid pump roller 11. As some embodiments of this application, the liquid pump roller 11 can change the flow rate of the flushing liquid by squeezing the first conduit 21.

[0035] The pressure measuring element 16 can be provided on the pressure measuring device 12. Specifically, the pressure measuring element 16 can be provided on the pressure measuring device 12 to transmit the pressure information of the liquid supply path 20 to the pressure measuring device 12 so that the liquid pump controller 10 can obtain the hydraulic pressure in the liquid supply path 20.

[0036] Temperature sensor 24 is connected to liquid pump controller 10. The connection between temperature sensor 24 and liquid pump controller 10 can be, but is not limited to, electrical or communication connections. In some embodiments of this application, temperature sensor 24 and liquid pump controller 10 are connected via wires. Temperature sensor 24 has a probe end 241, which can detect the liquid temperature within the liquid supply path 20. Furthermore, temperature sensor 24 can feed back temperature information to liquid pump controller 10, enabling liquid pump controller 10 to obtain the liquid temperature within the liquid supply path 20.

[0037] It should be noted that the liquid pump controller 10 can be understood as the controller of the medical irrigation equipment. The liquid pump controller 10 can control the liquid flow rate of the liquid supply path 20 through the liquid pump roller 11. The hydraulic pressure and temperature data of the liquid in the liquid supply path 20 can be fed back to the liquid pump controller 10. The liquid pump controller 10 can adjust the power of the heater 13 according to the hydraulic pressure, temperature and flow rate data so that the outlet temperature of the medical irrigation equipment is maintained in a suitable temperature range, so as to meet the requirements for precise control of irrigation fluid temperature during surgery.

[0038] Therefore, the power of the heater 13 can be controlled by the liquid pump controller 10 to provide a large amount of irrigation fluid at the required temperature, reducing the probability of intraoperative hypothermia in patients. Furthermore, the power of the heater 13 can be adjusted according to the feedback of irrigation fluid temperature, flow rate, hydraulic pressure, etc., so that the outlet temperature of the medical irrigation equipment is maintained within a suitable temperature range, meeting the requirements for precise control of irrigation fluid temperature during surgery, improving surgical safety and the quality of postoperative recovery for patients.

[0039] In some embodiments of this utility model, such as Figure 2As shown, the heater 13 includes a housing 30 and a heating element 14. The housing 30 defines a receiving space 15, which is connected to a first conduit 21 and adapted to be connected to a liquid source. At least a portion of the heating element 14 is housed in the receiving space 15. The heating element 14 can be connected to a liquid pump controller 10, which can control the heating element 14 to generate heat to heat the liquid in the receiving space 15.

[0040] The housing 30 defines a receiving space 15, which is connected to the first pipeline 21 and can be connected to a liquid source. The housing 30 is made of heat-resistant material, which can be constructed as, but is not limited to, high-temperature resistant plastic products. This can reduce the manufacturing cost of the housing 30 and allow for timely observation of the condition of the heating element 14, thereby reducing the risk of impurities adhering to the heating element 14 and corrosion of the heating element 14.

[0041] As some embodiments of this application, the heating element 14 is constructed as a titanium alloy heating rod.

[0042] In some embodiments of this application, the rinsing fluid can flow out from the liquid source and into the first pipeline 21 via the receiving space 15. In some embodiments of this application, a portion of the heating element 14 is housed in the receiving space 15, and in some embodiments of this application, the entire heating element 14 is housed in the receiving space 15.

[0043] The heating element 14 can be connected to the liquid pump controller 10. Specifically, the connection between the heating element 14 and the liquid pump controller 10 can be, but is not limited to, electrical connection. As some embodiments of this application, the heating element 14 and the liquid pump controller 10 are connected by a wire.

[0044] As some embodiments of this application, the heater 13 also includes a connecting wire, which is electrically connected to the liquid pump controller 10. The liquid pump controller 10 can control the heating element 14 to heat the flushing fluid in the accommodating space 15.

[0045] This configuration allows for precise heating of the irrigation fluid within the containment space 15 via the heating element 14, providing a large amount of irrigation fluid at the required temperature and reducing the probability of intraoperative hypothermia in patients. By housing at least a portion of the heating element 14 within the containment space 15, heat can be directly transferred to the irrigation fluid, reducing heat loss, improving heating efficiency, and enhancing the reliability of the medical irrigation equipment.

[0046] In some embodiments of this utility model, such as Figure 2 As shown, the heating element 14 is partially bent and arranged within the receiving space 15.

[0047] As some embodiments of this application, the portion of the heating element 14 housed in the receiving space 15 may be arranged in a serpentine bend. For example, the portion of the heating element 14 housed in the receiving space 15 may be repeatedly bent in an "S" shape and extend from one end of the receiving space 15 to the other end.

[0048] As some embodiments of this application, the portion of the heating element 14 housed in the receiving space 15 is arranged in a spiral. Specifically, the portion of the heating element 14 housed in the receiving space 15 spirals along the inner wall of the receiving space 15 to form a spring-like structure. The spacing of the spirals can be adjusted according to actual needs.

[0049] This configuration allows for a longer heating path within a smaller accommodating space 15, increasing the contact area between the heating element 14 and the flushing fluid flowing within the accommodating space 15, thereby improving heat transfer efficiency.

[0050] In some embodiments of this utility model, such as Figure 2 As shown, the housing 30 has an inlet 31 and an outlet 32. Both the inlet 31 and the outlet 32 ​​are connected to the receiving space 15. The inlet 31 is suitable for connecting to a liquid source, and the outlet 32 ​​is connected to the first pipeline 21. The probe end 241 is housed in the receiving space 15, and the distance between the probe end 241 and the outlet 32 ​​is smaller than the distance between the probe end 241 and the inlet 31.

[0051] As some embodiments of this application, inlet 31 and outlet 32 ​​are formed at opposite ends of housing 30. Both inlet 31 and outlet 32 ​​are connected to receiving space 15, and inlet 31 can be connected to liquid source. As some embodiments of this application, liquid source and inlet 31 are connected through third pipe 23 so that flushing liquid from liquid source can flow into receiving space 15 through third pipe 23.

[0052] The outlet 32 ​​is connected to the first pipe 21, the probe end 241 is housed in the receiving space 15, and the distance between the probe end 241 and the outlet 32 ​​is smaller than the distance between the probe end 241 and the inlet 31. In other words, the probe end 241 is closer to the outlet 32.

[0053] As some embodiments of this application, a pipe connector 33 is provided at both the inlet 31 and the outlet 32. The third pipe 23 is connected to the inlet 31 through the pipe connector 33, and the first pipe 21 is connected to the outlet 32 ​​through the pipe connector 33.

[0054] By making the distance between the probe end 241 and the outlet 32 ​​smaller than the distance between the probe end 241 and the inlet 31, the position of the probe end 241 can be reasonably set, allowing the probe end 241 of the temperature sensor 24 to monitor the temperature of the flushing fluid at the outlet 32 ​​and feed it back to the pump controller 10. The pump controller 10 then adjusts the power of the heater 13 according to the temperature of the flushing fluid at the outlet 32, reducing the temperature difference between the flushing fluid at the outlet 32 ​​and the flushing fluid sprayed from the medical flushing equipment. This meets the requirements for precise temperature control of the flushing fluid during surgery and is beneficial to improving the quality of postoperative recovery for patients.

[0055] In some embodiments of this utility model, such as Figure 2 As shown, the pressure measuring element 16 has a pressure sensing diaphragm 161, which can be disposed on the pressure measuring device 12 so that the liquid pump controller 10 can obtain the hydraulic pressure in the liquid supply path 20.

[0056] In other words, the pressure measuring element 16 has a pressure detection diaphragm 161. The pressure measuring element 16 can be installed on the pressure measuring device 12 so that the pressure detection diaphragm 161 is installed on the pressure measuring device 12. The pressure measuring device 12 can detect the hydraulic pressure in the liquid supply path 20 through the pressure detection diaphragm 161. The liquid pump controller 10 can adjust the hydraulic pressure in the liquid supply path 20 so that the outlet pressure is maintained in a suitable range.

[0057] This configuration enables the medical flushing equipment to monitor and precisely control the pressure within the fluid supply path 20 in real time, which helps improve the reliability of the medical flushing equipment.

[0058] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the liquid pump controller 10 has a first connection part 41 and a second connection part 42. The heater 13 can be connected to the first connection part 41, and the connection end 242 of the temperature sensor 24 can be connected to the second connection part 42.

[0059] The heater 13 can be connected to the first connection part 41. As some embodiments of this application, the heating element 14 of the heater 13 can be connected to the first connection part 41, and the temperature sensor 24 can be connected to the second connection part 42. Specifically, the connection end 242 of the temperature sensor 24 can be connected to the second connection part 42.

[0060] As some embodiments of this application, the first connecting part 41 is configured as a plug-in part, and the heating element 14 has a plug-in connector. The plug-in part and the plug-in connector are plugged in and engaged so that the first connecting part 41 is connected to the heating element 14.

[0061] As some embodiments of this application, the second connecting part 42 is configured as a plug-in part, and the connecting end 242 has a plug connector. The plug-in part and the plug connector are plugged in and engaged so that the second connecting part 42 is connected to the connecting end 242.

[0062] By enabling the heater 13 to be connected to the first connection part 41 and the connection end 242 of the temperature sensor 24 to be connected to the second connection part 42, the connection between the liquid pump controller 10 and the heater 13 and the temperature sensor 24 can be facilitated, which can significantly increase the installation efficiency of the medical flushing equipment.

[0063] In some embodiments of this utility model, such as Figure 2 As shown, the medical flushing device also includes a third conduit 23, which includes a main conduit 234 and at least one sub-conduit 231. The main conduit 234 is connected between the sub-conduit 231 and the heater 13. The end of the sub-conduit 231 away from the main conduit 234 has a puncture device 233. The sub-conduit 231 is adapted to be connected to a liquid source.

[0064] As some embodiments of this application, the third conduit 23 includes a main conduit 234 and a sub-conduit 231. As some embodiments of this application, the third conduit 23 includes a main conduit 234 and multiple sub-conduits 231, the number of which may be, but is not limited to, two, three, four, etc. As some embodiments of this application, the third conduit 23 includes a main conduit 234 and two sub-conduits 231.

[0065] The main pipe 234 is connected between the sub-pipe 231 and the heater 13. Specifically, the main pipe 234 is connected to the inlet 31 of the heater 13, and the sub-pipe 231 is connected between the liquid source and the main pipe 234, so that the flushing liquid in the liquid source can flow into the receiving space 15 through the third pipe 23.

[0066] The end of the sub-pipe 231 away from the main pipe 234 has a piercing device 233. In other words, the end of the sub-pipe 231 near the liquid source has a piercing device 233. The piercing device 233 can pierce the container (e.g., a bag) of the liquid source so that the flushing fluid in the liquid source can flow into the receiving space 15 of the heater 13 through the sub-pipe 231 and the main pipe 234.

[0067] When there are multiple sub-tubules 231, the medical flushing equipment can be connected to multiple liquid sources simultaneously to meet the liquid demand. By having a puncture device 233 at the end of the sub-tubule 231 away from the main tubing 234, it is easier to connect the third tubing 23 to the liquid source (e.g., a flushing fluid bag), which helps to improve the assembly speed of the third tubing 23 and the liquid source, and ensures that the flushing fluid is introduced into the supply flow path 20 under sterile conditions, thereby improving the safety and reliability of the medical flushing equipment.

[0068] In some embodiments of this utility model, such as Figure 2 As shown, the medical flushing device also includes a clip 232, which is detachably provided on the sub-tube 231 to cut off or open the sub-tube 231.

[0069] The buckle 232 can be constructed as, but is not limited to, a cantilever buckle, a ring buckle, a torsion buckle, etc. As some embodiments of this application, the buckle 232 of the medical rinsing device is constructed as a ring buckle.

[0070] The latch 232 is detachably disposed on the sub-pipe 231 to cut off or open the sub-pipe 231. As some embodiments of this application, the third pipe 23 includes a main pipe 234 and a sub-pipe 231, with the latch 232 detachably disposed on one sub-pipe 231 to cut off or open the sub-pipe 231. As some embodiments of this application, the third pipe 23 includes a main pipe 234 and multiple sub-pipes 231, with multiple latches 232 detachably and correspondingly disposed on multiple sub-pipes 231 to cut off or open the multiple sub-pipes 231.

[0071] Specifically, when the clip 232 clamps the corresponding sub-pipe 231, it can cut off the corresponding sub-pipe 231; when the clip 232 is removed from the corresponding sub-pipe 231, the corresponding sub-pipe 231 becomes open.

[0072] By making the buckle 232 detachable on the sub-pipe 231 to cut off or open the sub-pipe 231, the medical flushing equipment can easily control the flow between the liquid source and the heater 13 as needed, and medical staff can quickly switch the flow state of the flushing fluid, which helps to improve the reliability and convenience of the medical flushing equipment.

[0073] In some embodiments of this utility model, such as Figure 1 As shown, the liquid pump controller 10 has an operation area 43, which includes a start / stop unit 431, a pressure regulating unit 432, a flow rate regulating unit 433, and a temperature regulating unit 434. The start / stop unit 431 can control the start and stop of the liquid pump, the pressure regulating unit 432 and the flow rate regulating unit 433 can both regulate the rotational speed of the liquid pump roller 11, and the temperature regulating unit 434 can regulate the power of the heater 13 and / or the rotational speed of the liquid pump roller 11.

[0074] As some embodiments of this application, the start / stop unit 431 can be configured as a start / stop button, the pressure regulating unit 432 can be configured as a pressure regulating button, the flow rate regulating unit 433 can be configured as a flow rate regulating button, and the temperature regulating unit 434 can be configured as a temperature regulating button. The start / stop unit 431 can be triggered by pressing the start / stop button, the pressure regulating unit 432 can be triggered by pressing the pressure regulating button, the flow rate regulating unit 433 can be triggered by pressing the flow rate regulating button, and the temperature regulating unit 434 can be triggered by pressing the temperature regulating button.

[0075] As some embodiments of this application, pressing the start / stop button can trigger the start / stop unit 431 to start the liquid pump and drive the flushing fluid flow, and pressing the start / stop button again can trigger the start / stop unit 431 again to stop the liquid pump from driving the flushing fluid flow.

[0076] As some embodiments of this application, the rotational speed of the pump roller 11 can be adjusted by pressing the pressure adjustment button, thereby adjusting the pressure of the flushing fluid in the supply flow path 20.

[0077] As some embodiments of this application, the rotational speed of the pump roller 11 can be adjusted by pressing the flow rate adjustment button, thereby adjusting the flow rate of the flushing fluid in the supply flow path 20.

[0078] As some embodiments of this application, the rotational speed of the liquid pump roller 11 can be adjusted by pressing the temperature adjustment button, thereby adjusting the temperature of the flushing liquid in the liquid supply path 20.

[0079] As some embodiments of this application, the power of the heater 13 can be adjusted by pressing the temperature adjustment button to adjust the temperature of the flushing fluid in the liquid supply path 20.

[0080] As some embodiments of this application, the power of the heater 13 and the rotation speed of the liquid pump roller 11 can be adjusted by pressing the temperature adjustment button, so as to adjust the temperature of the flushing liquid in the liquid supply path 20.

[0081] As some embodiments of this application, the liquid pump controller 10 has a display screen 436, on which the pressure data, flow rate data, temperature data of the flushing fluid in the liquid supply path 20 and the rotational speed of the liquid pump roller 11 can be displayed, so as to facilitate adjustments by medical personnel.

[0082] This setup allows for simple and reliable regulation of the flow rate, pressure, and temperature of the flushing fluid in medical flushing equipment, enabling precise temperature control of the flushing fluid and improving the reliability and operational efficiency of the equipment.

[0083] In some embodiments of this utility model, such as Figure 1 As shown, the operation area 43 also includes a mode control unit 435. The trigger mode control unit 435 can adjust the working mode of the medical flushing device. The working modes include: pressure control mode, flow control mode, and natural mode.

[0084] In other words, the operation area 43 also has a mode control unit 435. By triggering the mode control unit 435, the working mode of the medical rinsing device can be adjusted. As some embodiments of this application, the mode control unit 435 can be configured as a mode control button. By pressing the mode control button, the working mode of the medical rinsing device can be adjusted.

[0085] The operating modes include: pressure control mode, flow control mode, and natural mode.

[0086] In pressure control mode, the pump controller 10 can adjust the rotational speed of the pump roller 11 according to the pressure of the flushing fluid in the supply flow path 20, thereby adjusting the flow rate of the flushing fluid.

[0087] In flow control mode, the pump controller 10 can drive the flushing fluid to flow out at a constant speed according to the set flushing fluid flow rate, without changing the flow rate according to the pressure in the supply flow path 20. Specifically, the pump roller 11 rotates according to the flow rate set by the pump controller 10, and the pressure sensor 12 does not work.

[0088] In natural mode, the pump controller 10 does not require setting pressure and flow rate; the flushing fluid can flow out naturally based on the pressure difference. It should be noted that in natural mode, the pressure sensor 16 does not need to be placed on the pressure sensor 12, nor does the first pipeline 21 need to bypass the pump roller 11. In other words, in natural mode, neither the pressure sensor 12 nor the pump roller 11 operates. Furthermore, the heater 13 operates in pressure control mode, flow control mode, and natural mode.

[0089] As some embodiments of this application, when using the medical flushing equipment, the sub-tube 231 can be cut off first using the clip 232, then the puncture device 233 at one end of the sub-tube 231 can be connected to the liquid source so that the flushing fluid can flow into the sub-tube 231. Then, the heater 13 can be connected to the first connection part 41, then the connection end 242 of the temperature sensor 24 can be connected to the second connection part 42, then the pressure measuring element 16 can be placed on the pressure measuring device 12 so that the liquid pump controller 10 can obtain the hydraulic pressure in the liquid supply flow path 20. Then, the first tube 21 can be bypassed by the liquid pump roller 11. Then, the working mode can be selected in the mode control part 435 of the operation area 43, and the heating temperature, flow rate and pressure data can be set. Then, the clip 232 can be opened to make the sub-tube 231 open. By pressing the start / stop button, the liquid pump can be started, and the flushing fluid can flow into the liquid supply flow path 20. The heater 13 is started to heat the flushing fluid. Finally, the flushing fluid with a suitable temperature can be obtained through the medical flushing equipment.

[0090] This configuration allows the medical flushing equipment to have multiple different working modes, enabling it to quickly switch between modes according to different usage needs, which improves the ease of use and reliability of the medical flushing equipment.
