Description

Technical Field

[0001] The present invention relates to the technical field of urological nursing, and particularly to a constant temperature and constant pressure flushing device for urological nursing. Background Art

[0002] Urology is a branch of medicine that specializes in the study of the urinary systems of both men and women and the male reproductive system. It is a subordinate specialty that has been subdivided from general surgery. Its treatment scope includes various urinary calculi and complex kidney stones, kidney and bladder tumors, prostatic hyperplasia, and prostatitis. After urological surgery, patients need to regularly perform flushing care on the affected area. During the flushing care process, it is necessary to maintain the constant temperature and constant pressure flushing of the flushing fluid to improve the comfort of the patients during the flushing care process.

[0003] After retrieval, a Chinese invention patent with the publication number CN116196504A discloses a sitting constant temperature and constant pressure flushing device, which includes a flushing device. The flushing device includes a flushing base, the surface of the flushing base is communicated with a cleaning box, a cleaning cavity is opened in the cleaning box, a flushing hole is opened on the upper surface of the cleaning box, a drainage hole is opened on the bottom wall of the cleaning box, a sleeve is fixedly connected inside the cleaning box, the sleeve extends into the cleaning cavity, and a cleaning tube is slidably connected inside the sleeve. Compared with the prior art, the Chinese invention patent with the publication number CN116196504A can avoid cross-infection when multiple different patients use the same flushing device.

[0004] However, when the above-mentioned sitting constant temperature and constant pressure flushing device preheats the waterproof cushion to improve the use comfort, it needs to energize the heating sheet and consume a certain amount of electric energy; and it cannot dry the affected area after flushing, that is, the function is relatively single; moreover, when disinfecting the inside of the cleaning cavity to prevent cross-infection, it is necessary to inject disinfectant into the flushing device and flush it through the cleaning tube. However, the injection of disinfectant will cause the residue of disinfectant inside the flushing device. In this way, it is necessary to inject cleaning water into the flushing device again to remove the residual disinfectant inside it, otherwise it will affect the next flushing care work. That is, the operation of disinfecting the inside of the cleaning cavity to prevent cross-infection is very inconvenient. Therefore, there is a need for a constant temperature and constant pressure flushing device for urological nursing that can preheat the cushion without consuming additional electric energy, can dry the affected area after flushing, and can simply and quickly disinfect the inside of the flushing cavity to prevent cross-infection. Summary of the Invention

[0005] The purpose of the present invention is to solve the drawbacks in the prior art that additional electric energy is required to preheat the cushion, the affected area after flushing cannot be dried, and the operation of disinfecting the inside of the cleaning cavity is very inconvenient, and to propose a constant temperature and constant pressure flushing device for urological nursing.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A constant temperature and constant pressure flushing device for urological care, comprising a device body, a flushing chamber arranged inside the device body, a flushing nozzle located at the bottom inside the flushing chamber, a waste liquid collection box, and a display controller arranged outside the device body. A front loading chamber and a lower placement chamber communicating with the flushing chamber are opened inside the device body. The flushing nozzle passes through the front loading chamber, and the waste liquid collection box is located inside the lower placement chamber. A cushion contacting the patient's buttocks is arranged at the top of the device body. A preheating chamber is opened inside the cushion. An output mechanism for outputting flushing liquid at a constant temperature and constant pressure is arranged at the back of the device body. The output mechanism includes a heat preservation liquid storage box fixedly connected to the back of the device body and located above the cushion. Symmetrically fixedly communicated between the bottom of the heat preservation liquid storage box and the outside of the rear end of the preheating chamber is a communicating pipe. A switching valve is installed outside the communicating pipe. The front bottom of the preheating chamber is fixedly communicated with an aggregation pipe located inside the front loading chamber and connected to the flushing nozzle. A constant pressure output pump located inside the front loading chamber is installed outside the aggregation pipe;

[0008] A rear loading chamber communicating with the flushing chamber is opened inside the device body. A self - resetting deflecting baffle is hinged outside the rear loading chamber. A drying mechanism for drying the patient's part is arranged inside the rear loading chamber. The drying mechanism includes a drying cover that can be located inside the flushing chamber;

[0009] A backrest cover for covering the cushion is hinged outside the device body. A middle loading groove is opened inside the inner side of the backrest cover. A disinfection mechanism for performing ultraviolet disinfection inside the flushing chamber is arranged inside the middle loading groove. The disinfection mechanism includes an ultraviolet lamp tube that can be located inside the flushing chamber.

[0010] The above - mentioned technical solution further includes:

[0011] One end of the flushing chamber close to the lower placement chamber gradually converges, and the lower placement chamber extends below the device body.

[0012] The switching valve and the constant-pressure output pump are both connected to the display controller and open and close synchronously. The constant-pressure output pump can provide a constant and adjustable pressure output for the flushing liquid, and the target pressure value of the constant-pressure output pump is displayed and controlled by the display controller; a constant-temperature heater and a temperature sensor are installed inside the heat-insulated liquid storage tank. The constant-temperature heater can heat the flushing liquid to a set temperature and keep the temperature constant. The target temperature value of the constant-temperature heater is the same as that of the temperature sensor and is displayed and controlled by the display controller; a liquid level sensor and a buzzer alarm are also installed inside and outside the heat-insulated liquid storage tank and are connected to each other. The switching valve and the constant-pressure output pump cooperate with each other to realize the preheating of the cushion and the constant-pressure output of the flushing liquid. The constant-temperature heater and the temperature sensor cooperate with each other to realize the constant-temperature output of the flushing liquid. The liquid level sensor and the buzzer alarm cooperate with each other to realize the output monitoring of the flushing liquid.

[0013] The self-resetting deflecting baffle is hinged below the outside of the rear installation cavity and is opposite to the position of the flushing nozzle.

[0014] The drying mechanism further includes an installation bin installed behind the rear installation cavity and fixedly connected to the bottom of the heat-insulated liquid storage tank. A filter screen is fixedly connected to the outside of the installation bin. A constant-temperature dryer is installed inside the installation bin. The target temperature value of the constant-temperature dryer is displayed and controlled by the display controller. An expansion air duct connected to the drying hood is fixedly connected to the air outlet of the constant-temperature dryer; an electro-hydraulic push rod connected to the display controller is installed inside the installation bin, and the output end of the electro-hydraulic push rod is fixedly connected to the end of the expansion air duct close to the drying hood; that is, the cooperation between the electro-hydraulic push rod and the constant-temperature dryer can realize the drying work of the patient's diseased part after flushing.

[0015] The disinfection mechanism further includes a limit multi-stage expansion rod installed outside the backrest cover and an electromagnetic suction block embedded inside the middle installation groove. The limit multi-stage expansion rod is installed in the middle outside of the backrest cover through an installation frame body. The output end of the limit multi-stage expansion rod passes through the electromagnetic suction block and is fixedly connected to a connecting iron block A. Telescopic connecting frames are symmetrically rotatably connected between the outside of the connecting iron block A and the inside of the middle installation groove. The ultraviolet lamp tubes are evenly distributed outside the telescopic connecting frames; when the electromagnetic suction block is powered off, the ultraviolet lamp tubes and the connecting iron block A will pull the limit multi-stage expansion rod and the telescopic connecting frames to extend due to their own gravity, so that the telescopic connecting frames drive the ultraviolet lamp tubes to deflect and unfold to disinfect the inside of the flushing cavity with ultraviolet rays.

[0016] A limiting block is arranged at the upper inner part of the waste liquid collection box. A piston sealing plate for sealing the waste liquid collection box is arranged at the top of the limiting block. A collection port and a sliding groove which are communicated with each other are formed at the top of the piston sealing plate. The collection port can be aligned with the flushing cavity. A sealing baffle for sealing the collection port and the flushing cavity is slidably connected inside the sliding groove. A connecting iron block B is embedded on one side of the sealing baffle. Elastic telescopic rods fixedly connected with the sliding groove are symmetrically embedded on the other side of the sealing baffle. The top of the lower cavity is communicated with a groove formed inside the device body. An electromagnetic repulsion block is slidably connected inside the groove. The bottom two side surfaces of the electromagnetic repulsion block are both arranged as abutting inclined surfaces. A connecting spring is fixedly connected between the top of the electromagnetic repulsion block and the inside of the groove. When the elastic telescopic rod is in a natural state, the sealing baffle can seal the collection port. When the electromagnetic repulsion block is electrified, the sealing baffle can slide to open the collection port.

[0017] The disinfection mechanism further includes a pressure sensor installed outside the device body and connected to the display controller. When the pressure sensor is pressed, the electromagnetic attraction block and the electromagnetic repulsion block can be electrified. That is, when the backrest cover is opened, the pressure sensor can be squeezed, so that the ultraviolet lamp tube contracts into the internal mounting groove for storage, and the sealing baffle slides to close the collection port to seal the waste liquid collection box.

[0018] The present invention has the following beneficial effects:

[0019] 1. When the present invention realizes the flushing work of constant temperature and constant pressure, the flushing liquid heated to the set temperature can first enter the preheating cavity to preheat the cushion, and then enter the inside of the flushing nozzle through the constant pressure output pump and be sprayed out through the flushing nozzle. That is, while the flushing nozzle sprays the flushing liquid to carry out constant temperature and constant pressure flushing on the patient's diseased part, the cushion contacting the patient's buttocks can be preheated in advance without consuming additional electric energy.

[0020] 2. By starting the electro-hydraulic push rod and the constant temperature dryer, the self-resetting deflecting baffle can be abutted and opened, and the telescopic air duct can be driven to extend, so that the drying cover extends into the flushing cavity and outputs hot air to dry the patient's diseased part, thereby improving the use function of the device.

[0021] 3. By closing the backrest cover to cut off the power supply of the electromagnetic attraction block and the electromagnetic repulsion block, the symmetric ultraviolet lamp tubes can be deflected and unfolded to disinfect the inside of the flushing cavity with ultraviolet rays, and the sealing baffle seals the waste liquid collection box to prevent the virus in the flushing waste liquid collected inside from spreading into the flushing cavity. That is, the simple and rapid ultraviolet disinfection work of the inside of the flushing cavity can be realized in a closed manner. Description of the Drawings

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1

[0036] As Figure 1 、 Figure 3 and Figures 5 - 11 shown, the constant temperature and constant pressure flushing device for urological care proposed by the present invention includes a device body 1, a flushing chamber 2 provided inside the device body 1, a flushing nozzle 3 located at the inner bottom of the flushing chamber 2, a waste liquid collection box 4, and a display controller 5 provided outside the device body 1. One end of the flushing chamber 2 close to the lower placement chamber 7 gradually converges. A front loading chamber 6 and a lower placement chamber 7 communicating with the flushing chamber 2 are opened inside the device body 1. The flushing nozzle 3 passes through the front loading chamber 6, and the lower placement chamber 7 extends below the device body 1. The waste liquid collection box 4 is located inside the lower placement chamber 7. A cushion 8 in contact with the patient's buttocks is provided at the top of the device body 1. A preheating chamber 9 is opened inside the cushion 8. Preheating the cushion 8 through the preheating chamber 9 can improve the comfort of using the device;

[0037] On the back of the device seat body 1, there is an output mechanism 100 for outputting the flushing liquid at a constant temperature and pressure. The output mechanism 100 includes a heat preservation liquid storage tank 101 fixedly connected to the back of the device seat body 1 and located above the cushion 8. Inside the heat preservation liquid storage tank 101, there is a constant temperature heater 106 and a temperature sensor 107. The constant temperature heater 106 can heat the flushing liquid to a set temperature and keep the temperature constant. The target temperature value of the constant temperature heater 106 is the same as that of the temperature sensor 107 and is displayed and controlled through the display controller 5. That is, the constant temperature heater 106 and the temperature sensor 107 can cooperate with each other to achieve the constant temperature output of the flushing liquid. Inside and outside the heat preservation liquid storage tank 101, there are also a liquid level sensor 108 and a buzzer alarm 109 connected to each other. That is, the liquid level sensor 108 and the buzzer alarm 109 can cooperate with each other to achieve the output monitoring of the flushing liquid;

[0038] Symmetrically and fixedly communicated between the bottom of the heat preservation liquid storage tank 101 and the outside of the rear end of the preheating chamber 9 is a communicating pipe 102. Outside the communicating pipe 102, there is a switching valve 103. The front bottom of the preheating chamber 9 is fixedly communicated with an aggregating pipe 104 located inside the front loading chamber 6 and connected to the flushing nozzle 3. Outside the aggregating pipe 104, there is a constant pressure output pump 105 located inside the front loading chamber 6. The switching valve 103 and the constant pressure output pump 105 are both connected to the display controller 5 and are opened and closed synchronously. The constant pressure output pump 105 can provide a constant and adjustable pressure output for the flushing liquid. The target pressure value of the constant pressure output pump 105 is displayed and controlled through the display controller 5. That is, the switching valve 103 and the constant pressure output pump 105 can cooperate with each other to achieve the preheating of the cushion 8 and the constant pressure output of the flushing liquid.

[0039] The working principle of this embodiment: As Figure 7 shown, when the flushing work at a constant temperature and pressure needs to be carried out, the constant temperature heater 106 can be started through the display controller 5, so that the constant temperature heater 106 heats the flushing liquid inside the heat preservation liquid storage tank 101 to the set temperature and keeps the temperature constant. Subsequently, the patient sits on the cushion 8, and then the switching valve 103 and the constant pressure output pump 105 are started through the display controller 5, so that the flushing liquid heated to the set temperature inside the heat preservation liquid storage tank 101 can enter the preheating chamber 9 through the communicating pipe 102. The flushing liquid entering the preheating chamber 9 can preheat the cushion 8. The flushing liquid entering the preheating chamber 9 then enters the inside of the flushing nozzle 3 through the aggregating pipe 104 and is sprayed out through the flushing nozzle 3. The constant temperature and constant pressure flushing liquid sprayed out by the flushing nozzle 3 can flush the diseased part of the patient. The flushing liquid after flushing enters the inside of the waste liquid collection box 4 through the flushing chamber 2;

[0040] During the flushing process, the constant-temperature heater 106 and the temperature sensor 107 cooperate with each other to achieve the constant-temperature output of the flushing liquid. The switching valve 103 and the constant-pressure output pump 105 cooperate with each other to achieve the preheating of the cushion 8 and the constant-pressure output of the flushing liquid. The liquid level sensor 108 and the buzzer alarm 109 cooperate with each other to achieve the output monitoring of the flushing liquid.

[0041] The main difference between this embodiment and the prior art is that when this embodiment realizes the flushing work with constant temperature and constant pressure, the flushing liquid heated to the set temperature can first enter the preheating chamber 9 to preheat the cushion 8, and then enter the inside of the flushing nozzle 3 through the constant-pressure output pump 105 and be sprayed out through the flushing nozzle 3. That is, while the flushing nozzle 3 sprays the flushing liquid to perform constant-temperature and constant-pressure flushing on the patient's diseased part, it can preheat the cushion 8 in contact with the patient's buttocks in advance without consuming additional electric energy.

[0042] Embodiment Two

[0043] As Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 and Figures 9 - 11 shown, based on Embodiment One, a rear loading cavity 11 communicating with the flushing cavity 2 is provided inside the seat body 1 of the device. A self-resetting offset baffle 12 is hinged outside the rear loading cavity 11. The self-resetting offset baffle 12 is hinged below the outside of the rear loading cavity 11 and is opposite to the position of the flushing nozzle 3. A drying mechanism 130 for drying the diseased part is arranged inside the rear loading cavity 11. The drying mechanism 130 includes a drying hood 131 that can be located inside the flushing cavity 2. The hot air output by the drying hood 131 can dry the diseased part of the patient.

[0044] The drying mechanism 130 further includes an installation chamber 132 installed behind the rear loading cavity 11 and fixedly connected to the bottom of the heat preservation liquid storage tank 101. A filter screen 133 is fixedly connected to the outside of the installation chamber 132. A constant-temperature dryer 134 is installed inside the installation chamber 132. The target temperature value of the constant-temperature dryer 134 is displayed and controlled through the display controller 5. An air outlet of the constant-temperature dryer 134 is fixedly connected to a telescopic air duct 135 connected to the drying hood 131. An electro-hydraulic push rod 136 connected to the display controller 5 is installed inside the installation chamber 132. The output end of the electro-hydraulic push rod 136 is fixedly connected to the end of the telescopic air duct 135 close to the drying hood 131. That is, the cooperation between the electro-hydraulic push rod 136 and the constant-temperature dryer 134 can achieve the drying work of the diseased part of the patient after flushing.

[0045] The working principle of this embodiment: Based on Embodiment One, as Figure 9As shown, when the constant temperature and constant pressure flushing work is completed and the drying work needs to be carried out, the electro-hydraulic push rod 136 and the constant temperature dryer 134 can be started through the display controller 5. When the electro-hydraulic push rod 136 starts to extend, it can abut and open the self-resetting deflecting baffle 12 and drive the telescopic air duct 135 to extend, so that the drying hood 131 extends into the flushing chamber 2. When the constant temperature dryer 134 starts, hot air can enter the interior of the drying hood 131 through the telescopic air duct 135, and the hot air output by the drying hood 131 can dry the affected part of the patient.

[0046] The main difference between this embodiment and the prior art is that in this embodiment, by starting the electro-hydraulic push rod 136 and the constant temperature dryer 134, the self-resetting deflecting baffle 12 can be abutted and opened, and the telescopic air duct 135 can be driven to extend, so that the drying hood 131 extends into the flushing chamber 2 and outputs hot air to dry the affected part of the patient, thereby improving the use function of the device.

[0047] Embodiment Three

[0048] As Figures 1 - 11 shown, based on Embodiment One and Embodiment Two, a backrest cover 14 for covering the seat cushion 8 is hinged to the outside of the device seat body 1. A middle mounting groove 15 is formed inside the backrest cover 14, and a disinfection mechanism 160 for performing ultraviolet disinfection on the inside of the flushing chamber 2 is arranged inside the middle mounting groove 15. The disinfection mechanism 160 includes an ultraviolet lamp tube 161 that can be located inside the flushing chamber 2;

[0049] The disinfection mechanism 160 further includes a limiting multi-stage telescopic rod 162 installed outside the backrest cover 14 and an electromagnetic suction block 163 embedded inside the middle mounting groove 15. The limiting multi-stage telescopic rod 162 is installed in the outer middle part of the backrest cover 14 through a mounting frame body 164. The output end of the limiting multi-stage telescopic rod 162 passes through the electromagnetic suction block 163 and is fixedly connected with a connecting iron block A165. Telescopic connecting frames 166 are symmetrically rotatably connected between the outside of the connecting iron block A165 and the inside of the middle mounting groove 15. The ultraviolet lamp tubes 161 are evenly distributed outside the telescopic connecting frames 166. When the electromagnetic suction block 163 is powered off, the ultraviolet lamp tubes 161 and the connecting iron block A165 will pull the limiting multi-stage telescopic rod 162 and the telescopic connecting frames 166 to extend due to their own gravity, so that the telescopic connecting frames 166 drive the ultraviolet lamp tubes 161 to deflect and unfold to perform ultraviolet disinfection on the inside of the flushing chamber 2;

[0050] At the upper inner part of the waste liquid collection box 4, a limit block 17 is provided. At the top of the limit block 17, a piston sealing plate 18 for sealing the waste liquid collection box 4 is provided. At the top of the piston sealing plate 18, a collection port 19 and a chute 20 that communicate with each other are opened. The collection port 19 can be aligned with the flushing chamber 2. Inside the chute 20, a sealing baffle 21 for sealing the collection port 19 and the flushing chamber 2 is slidably connected. On one side of the sealing baffle 21, an iron connecting block B 22 is embedded. On the other side of the sealing baffle 21, elastic telescopic rods 23 fixedly connected to the chute 20 are symmetrically embedded. When the elastic telescopic rods 23 are in the natural state, the sealing baffle 21 can seal the collection port 19. At the top of the lower chamber 7, a groove 24 opened inside the device body 1 is communicated. Inside the groove 24, an electromagnetic repulsion block 25 is slidably connected. The bottom two side surfaces of the electromagnetic repulsion block 25 are both provided as abutting inclined surfaces 26. Between the top of the electromagnetic repulsion block 25 and the inside of the groove 24, a connecting spring 27 is fixedly connected. When the electromagnetic repulsion block 25 is energized, the sealing baffle 21 can slide to open the collection port 19;

[0051] The disinfection mechanism 160 further includes a pressure sensor 167 installed outside the device body 1 and connected to the display controller 5. When the pressure sensor 167 is pressed, it can energize the electromagnetic attraction block 163 and the electromagnetic repulsion block 25. That is, when the backrest cover 14 is opened, it can squeeze the pressure sensor 167, so that the ultraviolet lamp tube 161 contracts into the internal mounting groove 15 for storage, and the sealing baffle 21 slides to close the collection port 19.

[0052] The working principle of this embodiment: Based on Embodiment 1 and Embodiment 2, as Figure 10 shown, when the constant temperature and constant pressure flushing work, drying work and disinfection work need to be completed, the backrest cover 14 can be closed so that the pressure sensor 167 is no longer pressed, so that the electromagnetic attraction block 163 and the electromagnetic repulsion block 25 are powered off;

[0053] When the electromagnetic attraction block 163 is powered off, the ultraviolet lamp tube 161 and the iron connecting block A 165 will pull the limit multi-stage telescopic rod 162 and the telescopic connecting frame 166 to elongate due to their own gravity. At the same time, the telescopic connecting frame 166 deflects, so that the symmetric ultraviolet lamp tubes 161 deflect and unfold to perform ultraviolet disinfection on the inside of the flushing chamber 2;

[0054] When the electromagnetic repulsion block 25 is powered off, the compressed elastic telescopic rods 23 will drive the sealing baffle 21 to reset above the collection port 19 to seal the waste liquid collection box 4, preventing the virus in the flushing waste liquid collected inside the waste liquid collection box 4 from spreading into the inside of the flushing chamber 2;

[0055] That is, closing the backrest cover 14 can realize the deflection and unfolding of the ultraviolet lamp tube 161 and the sealing of the bottom of the flushing chamber 2, so as to realize the closed ultraviolet disinfection inside the flushing chamber 2 to prevent the ultraviolet light from overflowing and causing harm to the human body;

[0056] After the disinfection work is completed, the waste liquid collection box 4 can be directly pulled outwards to clean and disinfect the flushing waste liquid inside it, and the waste liquid collection box 4 after cleaning and disinfection can be directly pushed into the inner part of the lower cavity 7;

[0057] The main difference between this embodiment and the prior art is that in this embodiment, by closing the backrest cover 14, the electromagnetic suction block 163 and the electromagnetic repulsion block 25 are powered off, so that the symmetric ultraviolet lamp tubes 161 can be deflected and unfolded to perform ultraviolet disinfection on the inside of the flushing cavity 2, and the sealing baffle 21 seals the waste liquid collection box 4 to prevent the virus in the flushing waste liquid collected inside it from spreading into the flushing cavity 2, that is, it can realize simple and rapid ultraviolet disinfection work inside the flushing cavity 2 in a closed manner.

[0058] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
