Description

Technical Field

[0001] This invention relates to the field of nursing equipment technology, and more specifically, to an intelligent nursing device with adjustable hardware and software. Background Technology

[0002] In hospital clinical practice, the common practice for nursing care of long-term bedridden patients, postoperative patients, elderly and frail patients, or hemiplegic patients is to use nursing beds for rehabilitation and recuperation during hospitalization. However, existing nursing beds can only provide simple lying or resting care for patients. Prolonged use can easily lead to pressure sores due to the patient's limited mobility, which can then cause infection and cause significant suffering. Furthermore, in clinical practice, to reduce pressure sores, nursing beds are sometimes combined with water mattresses or air mattresses for rehabilitation and recuperation during hospitalization. However, if the patient's condition changes and requires resuscitation, the patient is lying on the water mattress or air mattress, and the contents of the mattress or air mattress cannot be easily removed quickly, making it difficult for medical staff to perform resuscitation procedures and failing to meet practical application needs.

[0003] Chinese Patent Publication No. CN111419584B discloses an intelligent elderly care and rehabilitation bed. Its key technical features include: a bed board; support legs installed at the bottom of the bed board; an air cushion located at the upper end of the bed board, with micron-sized air vents and air inlets on its surface; and an air pump located at the bottom of the bed board, with its output end connected to the air inlet via an air inlet pipe. While this solution addresses the problem of pressure sores caused by poor patient mobility, it does not solve the problem of quickly expelling gas from the air cushion to facilitate resuscitation efforts by medical personnel.

[0004] How to solve the above problems has become an urgent technical challenge. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an intelligent nursing device with adjustable softness and hardness that is less likely to cause pressure sores in patients and facilitates emergency treatment by medical staff.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] An adjustable-firm intelligent nursing device includes a bed frame with self-locking casters, and a bed board structure for a patient to lie on. The bed board structure includes a support partition with perforated mesh embedded in the bed frame. At the bottom of the support partition is a base plate assembly connected to the bed frame for controlling the perforated state of the support partition. At the top of the support partition is a water mat for the patient to lie on, and the water mat is connected to a water supply structure on the bed frame. The water supply structure drives the water in the water mat to undulate to massage the patient. The base plate assembly and the water supply structure are both electrically connected to a control structure on the bed frame.

[0008] Preferably, the base plate assembly includes an I-shaped base disposed on the bed frame and located below the support partition. An electric push rod electrically connected to the control structure is provided at each of the four ends and the middle of the base, with the push rod end of the electric push rod facing upward. A limiting base plate with an outer shape adapted to the outer shape of the support partition is provided at the push rod end of the electric push rod. Several limiting protrusions with positions and sizes adapted to the positions and sizes of the corresponding perforated mesh holes of the support partition are provided on the top of the limiting base plate to control the perforated state of the support partition.

[0009] Preferably, the water cushion includes a water cushion body disposed on the top of the support partition for the patient to lie on, and when the support partition is in a hollow state, the corresponding part of the water cushion body can be embedded in the hollow mesh of the support partition under the action of gravity of water, and the upper and lower ends of the water cushion body are respectively provided with an inlet and an outlet connected to the water supply structure.

[0010] Preferably, the water supply structure includes a water storage tank disposed on the bed frame and located at one end of the base. An outlet connected to the inlet is provided at the upper end of one side of the water storage tank via a water outlet pipe. An inlet connected to the water outlet is also provided at the upper end of the other side of the water storage tank away from the outlet via a water inlet pipe. An electric valve electrically connected to the control structure is provided at the end of the water outlet pipe and the water inlet pipe near the water storage tank. The structure also includes a water supply component disposed in the water storage tank and connected to the outlet and the inlet, and the water supply component is electrically connected to the control structure.

[0011] Preferably, the water supply assembly includes a first silent water pump disposed in the water storage tank near the outlet end, the outlet end of the first silent water pump being connected to the outlet via a connecting pipe, and a second silent water pump disposed in the water storage tank near the inlet end, the inlet end of the second silent water pump being connected to the inlet via a connecting pipe, wherein the first silent water pump and the second silent water pump are both electrically connected to the control structure via conductive wire harnesses.

[0012] Preferably, the control structure includes a controller located on the bed frame near the water tank, which is electrically connected to the electric push rod, electric valve, first silent water pump, and second silent water pump via conductive wiring harness; a control panel located on the front side wall of the bed frame and electrically connected to the controller via conductive wiring harness; and a wireless communication module embedded inside the controller and electrically connected to the controller, which is wirelessly connected to a wireless receiving module located at the nurse station and the on-call doctor's room.

[0013] Preferably, the controller is a DVP32EH00M3 type PLC programmable controller.

[0014] Preferably, the wireless communication module is an E75-2G4M20S type wireless communication module.

[0015] Preferably, the wireless receiving module is an E41-400M20S type wireless receiving module.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In use, the self-locking casters move the bed frame, along with the bed board structure, water supply structure, and control structure, to a designated location. The control structure then activates the base plate assembly, which seals the perforated mesh of the support partition, making it flat and mounted on the bed frame. A water mattress from the bed board structure is then placed on the support partition and connected to the water supply structure. The control structure activates the water supply structure, injecting a predetermined amount of water into the water mattress, causing it to inflate. The patient is then placed lying on the water mattress. Simultaneously, the control structure activates the water supply structure to supply water to the water mattress at a preset flow rate, causing the water to flow in a peristaltic manner, thus massaging the patient, promoting blood circulation, and facilitating turning. This also reduces the risk of pressure sores when the patient lies down for extended periods. Furthermore, when the patient's condition changes and cardiopulmonary resuscitation (CPR) is required, the control structure sends predetermined resuscitation information to designated devices at the nurses' station and the on-duty doctor's office to alert the relevant nurses and doctors to provide timely treatment. During cardiopulmonary resuscitation (CPR), while sending predetermined information to alert the relevant nurses and doctors, the control structure activates the water supply structure according to a predetermined procedure, drawing water from the water cushion and storing it on the internal components of the water supply structure. Simultaneously, the control structure activates the base plate assembly, causing its components to move downwards and expose the perforated mesh of the supporting partition. The portion of the water cushion in contact with the perforated mesh of the supporting partition sinks along with the water under gravity into the perforated mesh of the supporting partition. Thus, through the combined effect of water retention in the perforated mesh of the supporting partition and water return from the water supply structure, the water on top of the water cushion is quickly drained, allowing the water cushion to lie flat against the supporting partition. Because the water cushion is changed from a soft to a firm form, it is less prone to shaking when the patient lies on it, facilitating resuscitation operations by doctors or nurses and effectively improving safety. Therefore, this invention has the advantages of reducing the risk of pressure sores and facilitating resuscitation operations for medical personnel. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] See Figures 1 to 3As shown, the present invention provides an intelligent nursing device with adjustable firmness, including a bed frame 2 with self-locking casters 1, and a bed board structure 3 for a patient to lie on. The bed board structure 3 includes a support partition 31 with perforated mesh embedded in the bed frame 2. A base plate assembly 32 connected to the bed frame 2 is provided at the bottom of the support partition 31 for controlling the perforated state of the support partition 31. A water mat 33 for a patient to lie on is provided at the top of the support partition 31, and the water mat 33 is connected to a water supply structure 4 provided on the bed frame 2. The water supply structure 4 drives the water in the water mat 33 to peristalse to achieve massage for the patient. The base plate assembly 32 and the water supply structure 4 are both electrically connected to a control structure 5 provided on the bed frame 2. During use, the self-locking casters 1 push the bed frame 2, along with the bed board structure 3, water supply structure 4, and control structure 5, to the designated location. Then, the control structure 5 activates the base plate assembly 32, using its components to seal the perforated mesh of the support partition 31, causing the support partition 31 to be flat and mounted on the bed frame 2. Next, the water pad 33 of the bed board structure 3 is placed on the support partition 31 and connected to the water supply structure 4. The control structure 5 then activates the water supply structure 4, which supplies water to the water pad 33. The water pad 33 is inflated by injecting a predetermined amount of water. The patient is then placed lying down on the water pad 33. Simultaneously, the control structure 5 activates the water supply structure 4 to supply water to the water pad 33 at a preset flow rate. This causes the water to flow in a peristaltic manner within the water pad 33, providing a massage effect to the patient, thereby promoting blood circulation and facilitating turning over. This also reduces the risk of pressure sores when the patient lies down for extended periods. Furthermore, if the patient's condition changes and cardiopulmonary resuscitation (CPR) is required, the control structure 5 sends a predetermined resuscitation message to the nurses' station and the on-duty doctor's office. The system is designed to alert nurses and doctors to perform CPR on patients promptly. Simultaneously, the control structure 5 activates the water supply structure 4, which operates according to predetermined steps to pump water from the water pad 33 back to its internal components. At the same time, the control structure 5 activates the base plate assembly 32, causing its components to lower and expose the perforated mesh of the supporting partition 31. This allows the water pad 33 to contact the perforated mesh of the supporting partition 31 in the water. Under the influence of gravity, the water, along with the corresponding portion of water, sinks into the perforated mesh of the support partition 31. Thus, through the combined effects of the water-holding capacity of the perforated mesh of the support partition 31 and the return water function of the water supply structure 4, the water on top of the water pad 33 can be quickly drained away, allowing the water pad 33 to lie flat against the support partition. By changing the water pad 33 from a soft to a hard form, it is less likely to cause shaking when the patient lies on the water pad 33, thereby facilitating emergency treatment for the patient by doctors or nurses and other medical personnel, effectively improving the safety of use.

[0025] In this embodiment, the base plate assembly 32 includes an I-shaped base 100 disposed on the bed frame 2 and located below the support partition 31. An electric push rod 200 electrically connected to the control structure 5 is provided at each of the four ends and the middle of the base 100, with the push rod end of the electric push rod 200 facing upward. A limiting base plate 300 with an outer shape adapted to the outer shape of the support partition 31 is provided at the push rod end of the electric push rod 200. Several limiting protrusions 400 with positions and shapes adapted to the positions and shapes of the corresponding perforated mesh holes of the support partition 31 are provided on the top of the limiting base plate 300 to control the perforated state of the support partition 31. During use, when it is necessary to seal the perforated mesh holes of the support partition 31, under the support and limitation of the base 100 of the base plate assembly 32, the electric push rod 200 is activated by the control structure 5 to work according to the predetermined working steps. The push rod end of the electric push rod 200 drives the limiting base plate 300 together with each limiting protrusion 400 to rise, and each limiting protrusion 400 seals the corresponding perforated mesh holes of the support partition 31, so that the support partition 31 is set in a flat shape on the bed frame 2, so as to place the water mattress 33 for the patient to lie down for nursing treatment. When it is not necessary to seal the perforated mesh holes of the support partition 31, under the support and limitation of the base 100, the electric push rod 200 is activated by the control structure 5 to work according to the predetermined working steps. The push rod end of the electric push rod 200 drives the limiting base plate 300 together with each limiting protrusion 400 to rise, and each limiting protrusion 400 seals the corresponding perforated mesh holes of the support partition 31, so that the support partition 31 is set in a flat shape on the bed frame 2, so as to place the water mattress 33 for the patient to lie down for nursing treatment. All the limiting protrusions 400 descend together to the designated position. At this time, the limiting protrusions 400 no longer block the perforated mesh of the support partition 31, thus exposing the perforated mesh of the support partition 31. The part of the water pad 33 that contacts the perforated mesh of the support partition 31 sinks into the perforated mesh of the support partition 31 under the gravity of the water. Then, with the water-holding function of the perforated mesh of the support partition 31 and the return function of the water supply structure 4, the water on the top of the water pad 33 can be quickly drained away, so that the water pad 33 is flat against the support partition. Since the water pad 33 is changed from a soft form to a hard form, it is not easy for the patient to shake when lying on the water pad 33, which makes it easier for doctors or nurses and other medical staff to perform rescue operations on the patient, effectively improving the safety of use.

[0026] In this embodiment, the water cushion 33 includes a water cushion body 500 disposed on the top of the support partition 31 for the patient to lie on. When the support partition 31 is in a hollow state, the corresponding part of the water cushion body 500 can be embedded in the hollow mesh of the support partition 31 under the action of gravity of water. The upper and lower ends of the water cushion body 500 are respectively provided with an inlet 600 and an outlet 700 connected to the water supply structure 4. During use, the water pad body 500 of the water pad 33 is placed on the support partition 31, and the inlet 600 and outlet 700 are connected to the corresponding components of the water supply structure 4. The water supply structure 4 is started by the control structure 5. The water supply structure 4 injects a predetermined amount of water into the water pad body 500 through the inlet 600, causing the water pad body 500 to inflate. The patient is then placed on the water pad body 500 while lying down. At the same time, the water supply structure 4 is started by the control structure 5 to supply water to the water pad body 500 according to the preset water flow rate, so that the water flows in a peristaltic manner within the water pad body 500 to massage the patient, thereby promoting the patient's blood circulation and achieving the effect of turning over. This makes it less likely for the patient to develop pressure sores when lying down for a long time.

[0027] In this embodiment, the water supply structure 4 includes a water storage tank 41 disposed on the bed frame 2 and located at one end of the base 100. An outlet 43 is provided at the upper end of one side of the water storage tank 41 and connected to the inlet 600 through an outlet pipe 42. An inlet 45 is provided at the upper end of the other side of the water storage tank 41 away from the outlet 43 and connected to the outlet 700 through an inlet pipe 44. An electric valve 46 electrically connected to the control structure 5 is provided at one end of the outlet pipe 42 and the inlet pipe 44 near the water storage tank 41. The water supply structure 47 also includes a water supply component 47 disposed in the water storage tank 41 and connected to the outlet 43 and the inlet 45, and the water supply component 47 is electrically connected to the control structure 5. The water supply assembly 47 includes a first silent water pump 471 located inside the water storage tank 41 near the outlet 43, with the outlet end of the first silent water pump 471 connected to the outlet 43 via a connecting pipe 472, and a second silent water pump 473 located inside the water storage tank 41 near the inlet 45, with the inlet end of the second silent water pump 473 connected to the inlet 45 via a connecting pipe 474. Both the first silent water pump 471 and the second silent water pump 473 are electrically connected to the control structure 5 via conductive wire harnesses.During use, when water is supplied to the water cushion body 500, the control structure 5 activates the electric valve 46 located on the outlet pipe 42 and the first silent water pump 471 of the water supply assembly 47. Under the water supply from the water storage tank 41, the first silent water pump 471 sequentially injects a predetermined amount of water into the water cushion body 500 through the connecting pipe 472, outlet 43, outlet pipe 42, and inlet 600, causing the water cushion body 500 to inflate. The patient is then placed lying down on the water cushion body 500. The control structure 5 activates the electric valve 46 located on the inlet pipe 44 and the second silent water pump 473. At this time, the water storage tank 41, the first silent water pump 471, the connecting pipe 472, the outlet 43, the outlet pipe 42, the inlet 600, the water pad body 500, the outlet 700, the inlet pipe 44, the inlet 45, the connecting pipe 474, and the second silent water pump 473 are sequentially connected to form a water supply circuit. The first silent water pump 471 supplies water to the water pad body 500 according to the preset water flow rate. The water cushion body 500 flows in a peristaltic manner to massage the patient, thereby promoting blood circulation and facilitating turning over, thus reducing the risk of pressure sores when the patient lies down for extended periods. During drainage of the water cushion body 500, the electric valve 46 on the outlet pipe 42 and the first silent water pump 471 are stopped by the control structure 5. With water stored in the storage tank 41, the second silent water pump 473 operates, sequentially flowing through the connecting pipe 474 and the inlet 45. The inlet pipe 44 and outlet 700 draw water from the water cushion body 500 back into the water storage tank 41 for storage, thereby draining the water on top of the support partition 31 and allowing the water cushion body 500 to lie flat against the support partition. By changing the water cushion body 500 from a soft to a hard form, it is less likely to shake when the patient lies on it, thus facilitating emergency treatment for the patient by doctors or nurses and other medical personnel, effectively improving the safety of use.

[0028] In this embodiment, the control structure 5 includes a controller 51 located on the bed frame 2 near the water tank 41, and the controller 51 is electrically connected to the electric push rod 200, the electric valve 46, the first silent water pump 471, and the second silent water pump 473 via conductive wire harnesses. It also includes a control panel 52 located on the front side wall of the bed frame 2 and electrically connected to the controller 51 via conductive wire harnesses, and a wireless communication module 53 embedded inside the controller 51 and electrically connected to the controller 51. The wireless communication module 53 is wirelessly connected to a wireless receiving module 54 located at the nurse station and the on-call doctor's room.

[0029] In this embodiment, the controller 51 is a DVP32EH00M3 type PLC programmable controller; the wireless communication module 53 is an E75-2G4M20S type wireless communication module; and the wireless receiving module 54 is an E41-400M20S type wireless receiving module.

[0030] In specific use of this embodiment, firstly, under the action of the self-locking casters 1, the bed frame 2, together with the bed board structure 3, the water supply structure 4, and the control structure 5, is moved to the designated location; secondly, under the support and limitation of the base 100 of the base plate assembly 32, a predetermined working signal is sent to the controller 51 through the control panel 52 of the operation control structure 5, and the controller 51 starts the electric push rod 200 to work according to the predetermined working steps. The push rod end of the electric push rod 200 drives the limiting base plate 300 together with each limiting protrusion 400 to rise, and each limiting protrusion 400... 0. Seal the corresponding perforated mesh holes of the support partition 31, so that the support partition 31 is set flat on the bed frame 2 to facilitate the placement of the water mattress 33 for the patient to lie down for nursing care and treatment; then, place the water mattress body 500 of the water mattress 33 on the support partition 31, and connect the water inlet 600 and the water outlet 700 to the water outlet pipe 42 and the water inlet pipe 44 of the water supply structure 4, respectively. Send a predetermined working signal to the controller 51 through the operation control panel 52, and the controller 51 will start the electric valve 46 located on the water outlet pipe 42 and the first water supply component 47. The silent water pump 471 operates, and under the water supply from the water storage tank 41, the first silent water pump 471 sequentially injects a predetermined amount of water into the water pad body 500 through the connecting pipe 472, outlet 43, water outlet pipe 42, and water inlet 600, causing the water pad body 500 to inflate. The patient is then placed lying down on the water pad body 500. Simultaneously, a predetermined operating signal is sent to the controller 51 via the operation control panel 52, and the controller 51 activates the electric valve 46 located on the water inlet pipe 44 and the second silent water pump 473. At this time, the water storage tank 41 and the first silent water pump 471 operate. Pump 471, connecting pipe 472, outlet 43, water outlet pipe 42, water inlet 600, water pad body 500, water outlet 700, water inlet pipe 44, inlet 45, connecting pipe 474, and second silent water pump 473 are connected in sequence to form a water supply circuit. The first silent water pump 471 supplies water to the water pad body 500 according to the preset water flow rate, so that the water flows in a peristaltic manner in the water pad body 500 to achieve massage for the patient, thereby promoting the patient's blood circulation and achieving the effect of turning over. In this way, the patient is less likely to develop pressure sores when lying down for a long time.Finally, when a patient's condition changes and cardiopulmonary resuscitation (CPR) is required, a predetermined working signal is sent from the control panel 52 to the controller 51. The controller 51 then activates the wireless communication module 53 to send predetermined resuscitation information to the wireless receiving modules 54 at the nurses' station and the on-duty doctor's room, alerting the relevant nurses and doctors to promptly perform CPR. Simultaneously, while sending the predetermined information to alert the nurses and doctors, the control panel 52 sends a predetermined working signal to the controller 51, causing the controller 51 to stop the electric valve 46 on the outlet pipe 42 and the first silent water pump 471. With the water stored in the storage tank 41, the second silent water pump 473 sequentially pumps water from the water pad body 500 back into the storage tank 41 via the connecting pipe 474, inlet 45, inlet pipe 44, and outlet 700. Simultaneously, supported by the base 100, the control panel 52 sends a predetermined working signal to the controller 51. A predetermined working signal is sent, and the controller 51 activates the electric push rod 200 to work according to the predetermined working steps. The push rod end of the electric push rod 200 drives the limiting base plate 300, along with each limiting protrusion 400, to descend to the designated position. At this time, the limiting protrusions 400 no longer block the perforated mesh of the supporting partition 31, thus exposing the perforated mesh of the supporting partition 31. The portion of the water cushion body 500 in contact with the perforated mesh of the supporting partition 31 sinks into the perforated mesh of the supporting partition 31 under the force of gravity. Therefore, through the combined effect of the water-holding capacity of the perforated mesh of the supporting partition 31 and the return water function of the water supply structure 4, the water on top of the water cushion body 500 at the supporting partition 31 can be quickly drained away, allowing the water cushion body 500 to lie flat against the supporting partition. When the patient lies on the water cushion body 500, it is less likely to shake, thus facilitating emergency treatment by doctors or nurses and other medical personnel, effectively improving the safety of use.

[0031] In summary, the structure described above has the advantages of being less likely to cause pressure sores in patients and facilitating emergency treatment for medical staff.

[0032] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.
