[0020] In a first aspect, this embodiment discloses a patient transfer method, such as Figure 1 As shown, patient transfer methods may include: Step S10, based on the patient's bed change requirement, the nursing trolley 01 is engaged and connected with the nursing bed 02; Step S20, based on the engagement and connection between the nursing cart 01 and the nursing bed 02, the posture data of the patient is obtained; wherein the posture data includes the patient's pain position; Step S30, based on the patient's pain location, control the support airbags 212 on both sides of the adjacent pain location to be inflated to a first pressure value; wherein the nursing bed 02 includes a second pad assembly 21; the second pad assembly 21 includes a second pad body 211, a support airbag 212, and a third mounting groove 213; the third mounting groove 213 is arranged on the second pad body 211 at intervals; the support airbag 212 is arranged in the third mounting groove 213; Step S40, based on the support airbags 212 on both sides of the adjacent pain position being inflated to a first pressure value, the driving part of the side shift plate 133 is moved toward the direction close to the pain position to the first area of ​​the second pad body 211, and the airbag strap 134 corresponding to the partial side shift plate 133 fixes the patient; wherein, the partial side shift plate 133 includes at least one side shift plate 133 with the smallest distance between one end of the side shift plate 133 close to the second pad body 211 and the pain position; the first area includes the spacing area between adjacent support airbags 212; the projection of the side shift plate 133 on the second pad body 211 completely overlaps with the first area; one end of the airbag strap 134 is fixedly connected to one end of the side shift plate 133, and the other end is detachably connected to the other end of the side shift plate 133; Step S50, based on the fact that part of the side shift plates 133 have moved into the first area and part of the airbag straps 134 have fixed the patient, the remaining support airbags 212 are inflated to a first pressure value, and the remaining side shift plates 133 are driven to move into the first area, and the remaining airbag straps 134 are used to fix the patient; Step S60 , based on all the side shift plates 133 moving into the first area and all the airbag straps 134 fixing the patient, the side shift plates 133 are driven to move to the set position of the nursing cart 01 .

[0021] In this embodiment, when a patient needs to be transferred via the nursing cart 01, multiple people are usually required to assist in transferring the patient from the nursing cart 01 to the nursing bed 02 or from the nursing bed 02 to the nursing cart 01. However, the transfer process not only requires a large amount of manpower, but also poses a great safety hazard.

[0022] The present invention provides a patient transfer method, which may include steps S10 to S60, which are described in detail below: Step S10, during the patient treatment process, the patient's position needs to be moved due to the use of some instruments, etc., but since the bed cannot be moved, the patient can be moved through the nursing cart 01. Based on the patient's bed change needs, the nursing cart 01 can be connected to the nursing bed 02 through the clamping part 114 of the nursing cart 01 and the clamping seat 202 of the nursing bed 02 to fix the relative position of the nursing cart 01 and the nursing bed 02, and ensure the stability of the connection between the nursing cart 01 and the nursing bed 02 during the patient transfer. In another embodiment, the nursing cart 01 may include a vertical movement component 11, and the vertical movement component 11 may include a movable frame 112 and a clamping part 114. One end of the locking portion 114 can be fixedly connected to an end of the movable frame 112 away from the frame assembly 10, and can be locked with the locking seat 202 on the nursing bed 02 to fix the relative position of the nursing cart 01 and the nursing bed 02, thereby ensuring the stability of the connection between the nursing cart 01 and the nursing bed 02 during the patient transfer process.

[0023] Step S20, after the nursing cart 01 is engaged with the nursing bed 02, the patient's posture data can be obtained through the medical record system (or other methods), so that corresponding actions can be taken according to the patient's posture data during the subsequent patient transfer process to ensure the stability and safety of the patient transfer process. The patient's posture data may include the patient's pain position.

[0024] Step S30, after obtaining the patient's pain location information, the support airbags 212 on both sides of the adjacent pain location can be controlled to be inflated to a first pressure value, so that both sides of the patient's pain location can be slightly lifted by the support airbags 212. The nursing bed 02 may include a second pad assembly 21, and the second pad assembly 21 may include a second pad body 211, a support airbag 212, and a third mounting groove 213. The third mounting groove 213 may be arranged at intervals on the second pad body 211 to fix the relative position of the support airbag 212. The support airbag 212 may be arranged in the third mounting groove 213, and the interval arrangement of the support airbag 212 on the second pad body 211 can ensure that the patient can be evenly stressed on the support airbag 212, thereby ensuring the safety and comfort of the patient during transfer.

[0025] Step S40, as Figure 2As shown, when the support airbags 212 on both sides of the patient's pain position are inflated to a first pressure value, the side shift plate 133 can be driven to move toward the pain position to the first area close to the second pad body 211, so that the airbag straps 134 corresponding to the side shift plate 133 can fix the patient's pain position. After being inflated to the first pressure value, the support airbag 212 can slightly lift the patient's pain position, reduce the friction between the side shift plate 133 and the patient during the movement process, and avoid excessive friction between the side shift plate 133 and the patient when the side shift plate 133 moves, causing harm to the patient. Among them, the partial side shift plate 133 can include at least one side shift plate 133 with the smallest distance from the pain position to one end of the side shift plate 133 close to the second pad body 211, to ensure that the patient's pain position can be completely fixed. The first area may include the spacing area between adjacent supporting airbags 212, and the projection of the side shift plate 133 on the second pad body 211 may completely overlap with the first area, ensuring that the side shift plate 133 can move horizontally along the direction of the third mounting groove 213, and ensuring the stability of the side shift plate 133 during movement. By fixing the patient's pain position first, it is helpful to avoid vibration or friction at the patient's pain position in subsequent steps, and reduce the impact on the patient's pain position. One end of the airbag strap 134 can be fixedly connected to one end of the side shift plate 133, ensuring the tightness of the connection between one end of the airbag strap 134 and the side shift plate 133, and avoiding the loose connection between one end of the airbag strap 134 and one end of the side shift plate 133, which affects the safety of the connection between the airbag strap 134 and the side shift plate 133. The other end of the airbag strap 134 can be detachably connected to the other end of the side shift plate 133 , so that the patient can be fixed on the side shift plate 133 through the airbag strap 134 , thereby driving the patient to move through the side shift plate 133 .

[0026] Step S50, when part of the side shift plate 133 moves into the first area and part of the airbag straps 134 fix the patient, the remaining support airbags 212 are controlled to be inflated to the first pressure value, the patient is slightly lifted by the support airbags 212, the friction between the side shift plate 133 and the patient is reduced during the movement, and then the remaining side shift plate 133 is driven to move into the first area, and the patient is further fixed by the remaining airbag straps 134, so as to ensure the tightness of the connection between the patient and the side shift plate 133, and ensure the safety of the connection between the patient and the side shift plate 133 during the patient transfer. In another embodiment, when the patient's pain position is directly above the side shift plate 133, the side shift plate 133 directly below the patient's pain position can be controlled not to move, and the side shift plates 133 on both sides of the pain position are moved toward the pain position to the first area close to the second pad body 211, and the pain position is fixed by fixing the airbag straps 134 on both sides of the pain position to the side shift plate 133.

[0027] Step S60, when the side shift plate 133 moves into the first area and all the airbag straps 134 completely fix the patient, the side shift plate 133 can be driven to move the patient so that the patient can be transferred to the set position of the nursing cart 01 to complete the transfer of the patient.

[0028] In some embodiments, step S30 includes: Step S31, based on the patient's pain position, control the support airbag 212 to be inflated to a second pressure value; wherein the nursing bed 02 includes a second pad assembly 21; the second pad assembly 21 includes a second pad body 211, a support airbag 212, and a third mounting groove 213; the third mounting groove 213 is arranged on the second pad body 211 at intervals; the support airbag 212 is arranged in the third mounting groove 213; Step S32, based on the support airbag 212 being inflated to the second pressure value, controlling the support airbags 212 on both sides of the adjacent painful area to continue to be inflated to the first pressure value; wherein the first pressure value is greater than the second pressure value.

[0029] In this embodiment, step S30 may include step S31 to step S32, and each step is described in detail as follows: In step S31, after determining the patient's pain location, the support airbag 212 can be controlled to be inflated to a second pressure value, so that the patient can be slightly lifted by the support airbag 212. Among them, the nursing bed 02 may include a second pad assembly 21, and the second pad assembly 21 may include a second pad body 211, a support airbag 212, and a third mounting groove 213, which is used to support the patient when the patient is transferred. The third mounting groove 213 can be arranged at intervals on the second pad body 211 to fix the relative position of the support airbag 212. The support airbag 212 can be arranged in the third mounting groove 213, and the interval arrangement of the support airbag 212 on the second pad body 211 can ensure that the patient can be evenly stressed on the support airbag 212, thereby ensuring the safety and comfort of the patient during the transfer process.

[0030] In step S32, after the support airbags 212 are inflated to the second pressure value, the support airbags 212 on both sides of the adjacent pain position can be controlled to continue to be inflated to the first pressure value, so that the patient's pain position can be raised again, reducing the friction between the side shift plate 133 near the pain position and the patient during the movement process, and avoiding excessive friction between the side shift plate 133 and the patient during the movement of the side shift plate 133 and causing harm to the patient. Among them, the first pressure value can be greater than the second pressure value, and by first inflating all the support airbags 212 to the second pressure value, the patient's entire body can be slightly lifted by the support airbags 212, and then the support airbags 212 on both sides of the adjacent pain position are controlled to continue to be inflated to the first pressure value, so that the patient's pain position can be raised again, thereby reducing the height difference between other parts of the patient and the pain position, and avoiding discomfort or damage to the patient's pain position.

[0031] In some embodiments, step S40 includes: Step S41, based on the support airbags 212 on both sides of the adjacent pain site being inflated to a first pressure value, the side shift plate 133 is driven to move a first distance toward the patient; Step S42, based on the side shift plate 133 moving a first distance, controlling the movable frame 112 of the nursing cart 01 to be lowered to a first height value; Step S43, based on the movable frame 112 being lowered to the first height value, the side shift plate 133 of the driving part is moved toward the direction close to the pain position to the first area of ​​the second pad body 211, and the airbag strap 134 corresponding to the partial side shift plate 133 fixes the patient; wherein, the partial side shift plate 133 includes at least one side shift plate 133 with the smallest distance between one end of the side shift plate 133 close to the second pad body 211 and the pain position; the first area includes the spacing area between adjacent supporting airbags 212; the projection of the side shift plate 133 on the second pad body 211 completely overlaps with the first area; one end of the airbag strap 134 is fixedly connected to one end of the side shift plate 133, and the other end is detachably connected to the other end of the side shift plate 133.

[0032] In this embodiment, step S40 may include step S41 to step S43, and each step is described in detail as follows: In step S41, after the support airbags 212 on both sides of the adjacent pain site are inflated to a first pressure value, the side shift plate 133 can be controlled to move a first distance toward the patient so that the side shift plate 133 can contact the end of the second pad assembly 21 away from the fixed bed frame 201.

[0033] In step S42, after the side shift plate 133 moves a first distance toward the direction approaching the patient, the movable frame 112 of the nursing cart 01 can be lowered to a first height value, thereby driving the second pad assembly 21 of the nursing bed 02 to deform downward through the side shift plate 133 that contacts the end of the second pad assembly 21 away from the fixed bed frame 201, thereby increasing the height difference between the side shift plate 133 and the supporting airbag 212 of the second pad body 211, and the supporting airbag 212 can bear more weight of the patient, further reducing the friction between the side shift plate 133 and the patient during movement, thereby avoiding excessive friction between the side shift plate 133 and the patient during movement to cause harm to the patient.

[0034] In step S43, after the movable frame 112 is lowered to the first height value, part of the side shift plate 133 can be driven to move toward the direction close to the pain position to the first area close to the second pad body 211, so that the airbag strap 134 corresponding to the part of the side shift plate 133 can fix the pain position of the patient. Part of the side shift plate 133 can include at least one side shift plate 133 whose end close to the second pad body 211 is at the smallest distance from the pain position, so as to ensure that the pain position of the patient can be completely fixed. The first area can include the interval area between adjacent supporting airbags 212, and the projection of the side shift plate 133 on the second pad body 211 can completely overlap with the first area, so as to ensure that the side shift plate 133 can move horizontally along the direction of the third mounting groove 213, and ensure the stability of the side shift plate 133 during the movement process. By fixing the pain position of the patient first, it is helpful to avoid vibration or friction of the pain position of the patient in subsequent steps, and reduce the influence on the pain position of the patient. One end of the airbag strap 134 can be fixedly connected to one end of the side shift plate 133 to ensure the tightness of the connection between the one end of the airbag strap 134 and the side shift plate 133, and avoid the loose connection between the one end of the airbag strap 134 and the one end of the side shift plate 133, which affects the safety of the connection between the airbag strap 134 and the side shift plate 133. The other end of the airbag strap 134 can be detachably connected to the other end of the side shift plate 133, so that the patient can be fixed on the side shift plate 133 through the airbag strap 134, thereby driving the patient to move through the side shift plate 133.

[0035] In some embodiments, the patient transfer method further comprises: Step S70, based on the side shift plate 133 moving toward the direction close to the first area, obtaining temperature change values ​​of the plurality of side shift plates 133; Step S71, based on the temperature change value of one side shift plate 133 being greater than or equal to the set temperature value, controlling the side shift plate 133 to stop moving and inflating the support airbags 212 on both sides of the side shift plate 133 to a third pressure value; wherein the third pressure value is greater than the first pressure value; Step S72: Based on the support airbags 212 on both sides of the side shift plate 133 being inflated to a third pressure value, the side shift plate 133 continues to move.

[0036] In this embodiment, the patient transfer method may further include steps S70 to S72, each of which is described in detail as follows: In step S70, when the side shift plate 133 moves toward the first area, the temperature change value of the side shift plate 133 can be obtained through the temperature sensor 152. Since the side shift plate 133 contacts the patient at a position where the side shift plate 133 contacts the patient during movement, causing the temperature of the contact portion of the side shift plate 133 with the patient to rise, it can be determined whether it is necessary to continue to inflate the support airbag 212 to reduce the friction between the patient and the side shift plate 133 based on the temperature change of the side shift plate 133.

[0037] Step S71, when the temperature change value of the side shift plate 133 is greater than the set temperature value, the side shift plate 133 can be controlled to stop moving and the support airbags 212 on both sides of the side shift plate 133 can be inflated to a third pressure value. The third pressure value can be greater than the first pressure value, and by inflating the support airbags 212 on both sides of the side shift plate 133 to the third pressure value, the patient is further lifted, the friction between the patient and the side shift plate 133 is reduced, and the safety and comfort of the patient during transfer are ensured.

[0038] Step S72, when the supporting airbags 212 on both sides of the side shift plate 133 are continuously inflated to the third pressure value, the side shift plate 133 can be controlled to continue to move and continue to transfer the patient.

[0040] In this embodiment, the patient transfer method may further include step S80 to step S81, each of which is described in detail as follows: Step S80, when the airbag strap 134 fixes the patient and drives the patient to move away from the first area through the side shift plate 133, the pressure fluctuation value of the side pressure plate can be obtained through the pressure sensor 153, and the size of the pressure fluctuation value can be used to determine whether the connection between the airbag strap 134 and the patient causes discomfort to the patient, thereby causing the patient to make movements that result in excessive pressure fluctuation values, thereby causing damage to the patient.

[0041] Step S81, when the connection between the airbag strap 134 and the patient causes discomfort to the patient, thereby causing the patient to make movements that result in excessive pressure fluctuations, the side shift plate 133 can be controlled to stop moving, and the airbag strap 134 can be deflated to a fourth pressure value, thereby ensuring safety and comfort during the patient transfer. After the airbag strap 134 is deflated to the fourth pressure value, the side shift plate 133 can be controlled to continue moving to continue transferring the patient.

[0042] In some embodiments, the patient transfer method further comprises: Step S90, based on the movement of the side shift plate 133, obtaining the patient's voice content; Step S91: based on the sound content matching the set sound range, the side shift plate 133 stops moving.

When the movement process causes discomfort to the patient, the patient may utter specific sound content, such as crying out in pain, etc. The patient's voice content can be used to determine whether the transfer process causes discomfort to the patient.

[0044] Step S91, when the movement process causes discomfort to the patient, the patient may utter specific sound content, such as crying out in pain, etc. The patient's sound content (such as crying out in pain, etc.) can be matched with the set sound range. At this time, the side shift plate 133 can be controlled to stop moving, the cause of the patient's discomfort can be checked and corresponding measures can be taken according to the actual situation.

[0045] In some embodiments, the posture data in step S20 also includes the patient's vital signs; the patient transfer method further includes: Step S61 , based on the vital sign not being within the set threshold range, driving the side shift plate 133 to stop moving.

[0046] In this embodiment, the posture data in step S20 may also include the patient's vital signs (including the patient's heart rate, blood pressure, and other signs that may endanger the patient's life) to determine whether the patient's state can be transferred.

[0047] The patient transfer method may further include step S61. The detailed description of step S61 is as follows: In step S61, when the transfer process causes discomfort to the patient, the patient's vital signs may be abnormal. When the patient's vital signs are not within the set threshold range, the side shift plate 133 can be driven to stop moving immediately, and emergency measures can be taken according to the actual situation of the patient.

[0048] In some embodiments, the posture data in step S20 also includes a real-time image of the patient; and the patient transfer method further includes: Step S62 , based on the fact that the patient's trunk movement trend in the real-time image is opposite to the movement direction of the side shift plate 133 , the airbag strap 134 is inflated.

[0050] The patient transfer method may further include step S62. The detailed description of step S62 is as follows: In step S62, when the airbag strap 134 does not fix the patient tightly, the patient and the side shift plate 133 may slide relative to each other. When the movement trend of the patient's trunk in the real-time image is opposite to the movement direction of the side shift plate 133, the patient and the side shift plate 133 may move relative to each other, thereby causing harm to the patient. The airbag strap 134 may be further inflated to make the connection between the patient and the side shift plate 133 tighter.
