DETAILED DESCRIPTION

[0034] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0035] Referring to Figures 1-3 , Figure 7 , Figure 8 and Figure 12The utility model provides a reduce pathogenic bacteria infection's defecation sickbed, including bed body 1 and along the width direction of bed body 1 remove toilet 2, the upper part of toilet 2 is vertically provided with liquid seal groove 21, liquid seal groove 21 is annular structure, and sealing sleeve 3 is fixedly arranged in the lower part of bed body 1, and toilet 2 has the state of extension and retraction when moving along the width direction of bed body 1, when toilet 2 is in the state of extension, toilet 2 extends from the side of bed body 1, when toilet 2 is in the state of retraction, toilet 2 is located directly below sealing sleeve 3, sealing ring 32 is slidably arranged in sealing sleeve 3 along the vertical direction, water is injected in liquid seal groove 21, when toilet 2 is in the state of retraction, sealing ring 32 extends into liquid seal groove 21, and the lower end surface of sealing ring 32 is below the liquid level of water in liquid seal groove 21, the upper part of sealing sleeve 3 is fixedly provided with electromagnet 31 that can adsorb sealing ring 32, when electromagnet 31 is electrified, sealing ring 32 retracts into sealing sleeve 3.

[0036] The existing sickbed mostly has supporting function, that is, whether the sickbed has folding or rotating function, the sickbed can only provide two rest functions of lying or sitting for the patient. In actual process, many patients have inconvenient movement condition, and as basic physiological demand, many patients need to get off the bed and walk a distance to reach the toilet when going to the toilet, and many toilets are ceramic tile floor, and there is the risk of slipping, and the patient also has the risk of falling during moving from the sickbed to the toilet, and for the basic physiological demand of going to the toilet, many patients need to go back and forth several times a day, so that the patient and the personnel assisting the patient movement are tired and there is the risk of the patient falling due to movement. Although there is a sanitary basin for the patient to use on the bed, when using, the sanitary basin needs to be placed on the bed, so that the height of the sanitary basin is higher than the height of the bed body 1, and the patient has an uncomfortable condition when using, and the strength of the sanitary basin is also required, and the sanitary basin needs to be cleaned manually after each use, and the excrement of some patients is infectious, and there is the risk of secondary transmission during handling.

[0037] In order to reduce the infection of bacteria and the patient's travel, the bed is redesigned, the specific structure and working principle are as follows, the button 11 is arranged on the side of the bed body 1, when the patient needs to go to the toilet, the patient's nurse or family member or the patient himself presses the button 11, which can make the toilet bowl 2 move along the width direction of the bed body 1. The toilet bowl 2 includes a flushing system, which is similar to the flushing system of the conventional toilet bowl 2, and the flushing system is formed by rotating water flow to form suction and flush the objects in the toilet bowl 2. The flushing system is not described here. After the button 11 is pressed, the toilet bowl 2 gradually extends from the bottom of the bed body 1 along the width direction of the bed body 1. When the toilet bowl 2 is completely extended from the bottom of the bed body 1, the toilet bowl 2 is in the extended state. It is worth noting that before the toilet bowl 2 extends from one side of the bed body 1, the sealing ring 32 is in the state of extending into the liquid seal groove 21. At this time, the lower end surface of the sealing ring 32 is below the liquid level of the water in the sealing groove. In this way, the toilet bowl 2 can be liquid sealed to avoid the odor in the toilet bowl 2 from spreading to the outside. When the toilet bowl 2 needs to be moved from the bottom of the bed body 1, the electromagnet 31 arranged on the sealing sleeve 3 is first powered on. The electromagnet 31 after power on attracts the sealing ring 32, and the sealing ring 32 is retracted in the vertical direction to the sealing sleeve 3. At this time, the sealing ring 32 slides out of the liquid seal groove 21, and the sealing ring 32 removes the liquid seal of the water in the liquid seal groove 21. In this way, the toilet bowl 2 can move smoothly along the width direction of the bed body 1. Since the toilet bowl 2 in the extended state is located at one side of the bed body 1, the patient basically does not need to stand when going to the toilet, and only needs to sit up from the bed body 1 and move to the toilet bowl 2 located at one side of the bed body 1.

[0038] An automatic sensor is arranged on the toilet bowl 2, that is, when the patient leaves the toilet bowl 2 after finishing going to the toilet, the flushing system of the toilet bowl 2 automatically flushes. The selection of the automatic sensor is as follows: foot touch type, pressure type, infrared sensor type, etc. The automatic sensor used here is pressure type, that is, a first pressure sensor is arranged on the upper part of the toilet bowl 2. When the patient sits on the toilet bowl 2, the toilet bowl 2 can detect the pressure. When the patient leaves the toilet bowl 2, the first pressure sensor cannot detect the pressure, and the flushing system starts to flush. At this time, the toilet bowl 2 has not been retracted, and the first pressure sensor does not identify the pressure for a certain time. Then, the toilet bowl 2 is retracted along the width direction of the bed body 1. When the toilet bowl 2 switches to the retracted state, the electromagnet 31 is powered off, and the sealing ring 32 falls into the liquid seal groove 21. The sealing ring 32 liquid seals the liquid seal groove 21, avoids the odor in the toilet bowl 2 from spreading to the surrounding of the bed body 1, reduces the probability of the part of bacteria in the toilet bowl 2 spreading through the air, avoids the patient from moving back and forth when going to the toilet, and further avoids the patient from falling down during the moving process, thereby reducing the pain of the patient.

[0039] In order to ensure privacy, a curtain 5 can also be added to the periphery of the bed body 1 as needed, which is pulled up to ensure privacy when the patient needs to use the toilet. A backrest 4 is movably arranged in the vertical direction at the upper part of the side of the toilet 2 close to the bed body 1. When the toilet 2 is in the extended state, the backrest 4 is extended from the toilet 2, and the backrest 4 provides support to the waist of the patient sitting on the toilet 2. The backrest 4 is driven by electricity.

[0040] Referring to Figures 1-12 A first pressure sensor is arranged at the upper part of the toilet 2, which is used to detect external pressure. A flushing system is arranged in the toilet 2. When the first pressure sensor first detects pressure and then the pressure disappears, the flushing system starts flushing.

[0041] Referring to Figures 1-12 The first pressure sensor also has a preset rated time. A timer is also arranged on the toilet 2. When the external pressure disappears, the timer starts timing. When the timing time of the timer reaches the rated time, the toilet 2 is retracted into the bed body 1 along the width direction of the bed body 1.

[0042] In this way, when the patient leaves the toilet 2, the flushing system automatically starts flushing, avoiding the situation that some patients forget to flush after use. At the same time, a timer is also arranged on the toilet 2, which starts timing when the first pressure sensor cannot detect external pressure. When the first pressure sensor cannot detect external pressure, it means that the patient has left the toilet 2 and moved to the bed body 1. However, there is a situation that although the patient has left the toilet 2 and moved to the bed body 1, the patient may fall during the moving process. In this way, the toilet 2 in the extended state can provide certain support to the patient to avoid the situation of falling. Therefore, the setting of the rated time for the first pressure sensor can provide sufficient time for the patient to safely move from the toilet 2 to the bed body 1.

[0043] Referring to Figure 3 and Figure 4 A lifting ring 22 is movably arranged in the extension direction of the liquid seal groove 21 in the liquid seal groove 21. A plurality of water leakage holes 221 are vertically arranged on the lifting ring 22. The lifting ring 22 has a highest position and a lowest position in the vertical movement path. When the toilet 2 is in the extended state, the lifting ring 22 is located at the highest position, and the upper end surface of the lifting ring 22 is coplanar with the upper end surface of the toilet 2. When the toilet 2 is in the retracted state, the lifting ring 22 is located at the lowest position, and the upper end surface of the lifting ring 22 is located at the upper end surface of the toilet 2.

[0044] When the toilet 2 is in the retracted state, the lifting ring 22 is in the lowest position, at this time, the lifting ring 22 is below the water level in the liquid seal groove 21, when the toilet 2 is in the extended state, the lifting ring 22 is in the highest position, at this time, the lifting ring 22 is above the water level in the liquid seal groove 21, when the lifting ring 22 rises from the lowest position to the highest position or falls from the highest position to the lowest position, the water in the liquid seal groove 21 can flow through the water leakage hole 221 on the lifting ring 22, ensuring that the water in the liquid seal groove 21 will not overflow due to the lifting of the lifting ring 22, a wiping member 222 is fixedly arranged on the side wall of the bed body 1, when the toilet 2 is extended, the wiping member 222 wipes the upper end surface of the lifting ring 22 on the toilet 2, because when the toilet 2 switches from the retracted state to the extended state, the lifting ring 22 gradually rises from below the water level in the liquid seal groove 21 to the upper end surface height of the toilet 2, so there is water stain on the upper end surface of the lifting ring 22, and the water stain is wiped off by the wiping member 222 to avoid the discomfort of the patient during use.

[0045] With reference to Figures 8-10 A follow-up unit 23 is arranged at the lower part of the lifting ring 22, the follow-up unit 23 comprises a lifting groove 234 which is vertically arranged below the liquid seal groove 21, a follow-up plate 231 which is vertically slidably arranged in the lifting groove 234, an extension rod 233 which is fixedly connected with the lifting ring 22 and the follow-up plate 231 and penetrates through the bottom of the liquid seal groove 21, and a guide rail 232 which is horizontally arranged at one side of the toilet 2 and comprises a first horizontal guide section and a second horizontal guide section, the height of the first horizontal guide section being lower than that of the second horizontal guide section.

[0046] The follow-up unit 23 further comprises a lifting frame 235 and a roller 236, the lifting frame 235 is fixedly arranged at the side of the follow-up plate 231, the roller 236 is rotatably arranged on the lifting frame 235 and rolls with the guide rail 232, when the toilet 2 is in the extended state, the roller 236 is in the second horizontal guide section, when the toilet 2 is in the retracted state, the roller 236 is in the first horizontal guide section, because the follow-up plate 231 is fixedly connected with the lifting frame 235 and the lifting ring 22 is fixedly connected with the follow-up plate 231 through the extension rod 233, so when the roller 236 rises and falls on the guide rail 232, the lifting ring 22 can rise and fall synchronously with the lifting frame 235.

[0047] With reference to Figure 5 , Figure 9 , Figure 11 and Figure 12The cleaning unit 24 is arranged at the lower part of the bed body 1, and the cleaning unit 24 comprises a cleaning pipe 241 horizontally fixedly arranged at the lower part of the bed body 1, the cleaning pipe 241 penetrating into the toilet bowl 2 from one side of the bed body 1 along the width direction of the bed body 1, the cleaning pipe 241 is in sliding fit with the toilet bowl 2 along the width direction of the bed body 1, one end of the cleaning pipe 241 is provided with a rotating unit 242 for driving the cleaning pipe 241 to rotate around the axis of the cleaning pipe 241, and a plurality of spray holes are uniformly distributed on the cleaning pipe 241, and the spray holes can spray water flow.

[0048] The cleaning unit 24 further comprises a water pump 243 and a water tank 244, the water tank 244 is arranged at one side of the cleaning pipe 241, the water pump 243 is arranged on the water tank 244, the water tank 244 is the same as the cleaning pipe 241, and the water pump 243 is used for injecting water in the water tank 244 into the cleaning pipe 241, the water flow entering the cleaning pipe 241 is sprayed through the spray holes, so as to realize cleaning of the toilet bowl 2. When the toilet bowl 2 is switched between the retracted state and the extended state, when the toilet bowl 2 is in the extended state, the cleaning pipe 241 does not extend into the toilet bowl 2, and when the toilet bowl 2 is in the retracted state, the cleaning pipe 241 extends into the toilet bowl 2.

[0049] Referring to Figure 9 and Figure 12 : A gear ring 2421 is fixedly arranged at the end of the cleaning pipe 241, a gear 2422 is rotatably arranged at one side of the gear ring 2421, the gear 2422 is in meshing with the gear ring 2421, a first rotary driver 2423 is arranged at the end of the gear 2422, and the first rotary driver 2423 is used for driving the gear 2422 to rotate.

[0050] The first rotary driver 2423 is preferably a servo motor, when the toilet bowl 2 is in the retracted state, the first rotary driver 2423 and the water pump 243 are started at the same time, the first rotary driver 2423 drives the cleaning pipe 241 to rotate, so that the cleaning pipe 241 performs overall flushing on the toilet bowl 2 through the spray holes, thereby realizing the self-cleaning function of the toilet bowl 2.

[0051] Referring to Figure 3 : Extension plates 26 are fixedly arranged at two sides of the toilet bowl 2 respectively, and second pressure sensors are fixedly arranged at the upper parts of the extension plates 26, and the second pressure sensors also have a rated time, when the second pressure sensors and the first pressure sensors do not detect pressure at the same time and continuously for the rated time, the toilet bowl 2 is retracted.

[0052] The extension plates 26 are arranged on both sides of the toilet 2, so that the patient has more support points when moving between the bed body 1 and the toilet 2, avoiding the patient from falling when moving. Since the extension plates 26 are fixedly arranged on both sides of the toilet 2, when the toilet 2 is extended, the extension plates 26 arranged on the side of the toilet 2 move synchronously with the toilet 2. Therefore, when the first pressure sensor and the second pressure sensor do not sense pressure, the toilet 2 can be retracted smoothly, otherwise, if the patient is on the extension plate 26 at this time, and the first pressure sensor does not detect pressure, the patient will accidentally fall off the extension plate 26.

[0053] With reference to Figure 12 : The inner ring side height of the liquid seal groove 21 is lower than the outer ring side height of the liquid seal groove 21.

[0054] According to the short board effect, the water level in the liquid seal groove 21 will not be higher than the inner ring side height of the liquid seal groove 21. Therefore, when the cleaning unit 24 cleans the toilet 2, the water falling into the liquid seal groove 21 will overflow from the inner ring side of the liquid seal groove 21, avoiding the water in the liquid seal groove 21 from overflowing from the outer side of the toilet 2.

[0055] With reference to Figure 5 and Figure 6 : The lower part of the toilet 2 is provided with a moving device 25 for driving the toilet 2 to move along the width direction of the bed body 1. The moving device 25 includes a second rotary driver 251, a threaded rod 252, and a guide rod 253. The threaded rod 252 is arranged through the toilet 2 along the width direction of the bed body 1 at the bottom of the toilet 2, and is threadedly connected with the toilet 2. The guide rod 253 is arranged on one side of the threaded rod 252 along the extension direction of the threaded rod 252 and parallel to the threaded rod 252, and penetrates through the toilet 2 and is slidably connected with the toilet 2 along the width direction of the bed body 1. The second rotary driver 251 is arranged at the end of the threaded rod 252, and is used for driving the threaded rod 252 to rotate.

[0056] The second rotary driver 251 is preferably a servo motor. When the second rotary driver 251 is started, the second rotary driver 251 drives the threaded rod 252 to rotate, and then drives the toilet 2 to move along the width direction of the bed body 1.

[0057] Working principle: the button 11 is arranged on the side of the bed body 1, when the patient needs to go to the toilet, the patient's nurse or family member or the patient himself presses the button 11, the electromagnet 31 is powered on to attract the sealing ring 32, the sealing ring 32 is retracted into the sealing sleeve 3 under the adsorption of the electromagnet 31, at this time the sealing ring 32 slides out of the liquid seal groove 21, the sealing ring 32 removes the liquid seal of the water in the liquid seal groove 21, the toilet 2 gradually extends from the bottom of the bed body 1 along the width direction of the bed body 1, when the toilet 2 is completely extended from the bottom of the bed body 1, the toilet 2 is in the extended state, it is worth noting that before the toilet 2 extends from one side of the bed body 1, the sealing ring 32 is in the state of extending into the liquid seal groove 21, at this time the lower end face of the sealing ring 32 is below the liquid level of the water in the sealing groove, so that the liquid seal of the toilet 2 can be realized, and the smell in the toilet 2 is prevented from spreading to the outside.

[0058] Since the toilet 2 in the extended state is located on one side of the bed body 1, when the patient goes to the toilet, the patient basically does not need to stand, only needs to sit up from the bed body 1 and move to the toilet 2 on one side of the bed body 1, after the patient finishes going to the toilet, when the patient gets off from the toilet 2, the flushing system of the toilet 2 automatically flushes, the upper part of the toilet 2 is provided with a first pressure sensor, when the patient sits on the toilet 2, the toilet 2 can detect the pressure, when the patient gets off from the toilet 2, the first pressure sensor cannot detect the pressure, after the first pressure sensor does not identify the pressure for a rated time, the toilet 2 is retracted into the bed body 1 along the width direction of the bed body 1, when the toilet 2 switches to the retracted state, the electromagnet 31 is powered off, the sealing ring 32 falls into the liquid seal groove 21, the sealing ring 32 liquid seals the liquid seal groove 21, avoids the smell in the toilet 2 from spreading to the surrounding of the bed body 1, reduces the probability that part of the bacteria in the toilet 2 spreads through the air, at the same time, the patient does not need to move back and forth when going to the toilet, thereby avoiding the patient from falling down during the moving process, and reducing the pain of the patient.
