Description

Technical Field

[0001] The present invention relates to the technical field dedicated to burn patient care beds, and specifically to a device for burn dressing change. Background Art

[0002] In the clinical treatment and care process of burn patients, as an important medical device, the functionality of the hospital bed has a direct impact on the rehabilitation effect of patients and the work efficiency of medical staff.

[0003] To improve the nursing efficiency and reduce the work intensity of medical staff, some special hospital beds for burn patients on the market adopt the design of automatic sheet replacement. For example, in the prior art "A Reel-Type Disposable Sheet Automatic Replacement Device" (Publication No.: CN110575343A), drum devices driven by motors are provided at both ends of the hospital bed. The rollers in the collection bin are rotated by the motor to wind up the old sheet, and the new sheet in the supply bin is re-laid on the bed surface under the winding action to achieve the replacement of the old sheet. This automatic sheet replacement method has improved the time-consuming and laborious problem of traditional manual sheet replacement to a certain extent and enhanced the convenience of using the hospital bed. However, there are still the following technical problems:

[0004] 1. When a doctor performs dressing change on a burn patient, it is usually necessary to change the sheet to prevent the wound fluid on the old sheet from contaminating the skin and causing infection. In the existing technology, the device drags the sheet in the supply bin from one end to the other through the convolution of the roller to achieve replacement. If the patient presses on the sheet, the roller cannot drag the sheet. Therefore, it is necessary for the patient to get off the bed before the sheet can be replaced. For burn patients, especially severely burned patients, their skin is severely damaged and their bodies are extremely fragile. During the sheet replacement process, if the patient is forced to get up or transfer, it may cause the wound to crack, trigger wound infection, increase the patient's pain, and prolong the recovery period, thus increasing the safety risk for the doctor during the dressing change of the patient; at the same time, the patient getting off the bed for sheet replacement also reduces the continuity of using the hospital bed and the efficiency of nursing work, and cannot meet the high-efficiency, safe, and comfortable nursing needs of burn patients.

[0005] 2. For some patients with burns on multiple parts of the body, the existing technology makes it difficult for the medical staff to change the dressings because the wounds are blocked by the bed surface. The reason is that in the process of burn dressing change, the bandage needs to be removed first, and the old gauze and dressing on the wound are taken off. If there is adhesion between the old gauze and the skin at the wound, a disinfectant needs to be sprayed to moisten the wound surface to facilitate the tearing of the gauze. Then the wound is cleaned and disinfected again, and an external gel-like drug is applied to the new gauze and then covered on the wound surface. Finally, the gauze is fixed with tape for small wounds, and for large wounds, bandage winding is also required. To complete this series of complex dressing change processes, medical staff need to move the patient to a suitable position to separate the wound surface from the bed surface for easy operation by the medical staff. However, the burn wound surface is extremely sensitive and fragile, and it is difficult to move the patient to change the position during dressing change. Summary of the Invention

[0006] The present invention provides a burn dressing change device, which can solve the problems in the prior art that the treatment bed requires the patient to frequently change positions for the medical staff to change the dressings and replace the bed sheet, etc., resulting in easy wound cracking and infection when severely burned patients get up and move, prolonging the rehabilitation period, increasing the safety risk and reducing the efficiency of nursing and dressing change.

[0007] The present application provides the following technical solution: A burn dressing change device, comprising a bracket, a bed body fixed on the bracket, and a replacement unit for replacing the bed sheet;

[0008] Support members are provided at the head and tail of the bed body, an intermediate pad is provided in the middle of the bed body, and an electric push rod is provided below the bed body. The electric push rod is used to lift the support member to a certain height;

[0009] The replacement unit includes a bed sheet replacement mechanism, and the bed sheet replacement mechanism includes a roller and a guide roller fixed at the tail end of the bed body;

[0010] The replacement unit further includes a bed sheet stacking mechanism, and the bed sheet stacking mechanism is used to stack the bed sheets into a repeatedly circuitous laminated shape; the stacked bed unit is located above the intermediate pad, and one side of the bed sheet bypasses the guide roller and is fixed to the roller.

[0011] Advantageous Effects:

[0012] 1. Reduce the risk of wound injury and infection. For severely burned patients, especially those with multiple burns on the front and back of the body, the treatment beds in the existing technology will block the wound surface, resulting in the need for medical staff to push the patient multiple times to change the body position to expose the wound for dressing change operations. However, pushing the patient multiple times is extremely likely to stretch and squeeze the wound, easily leading to wound infection. Moreover, if the old gauze at the wound adheres to the skin, it is also necessary to spray disinfectant to moisten the wound surface so that the medical staff can carefully tear off the gauze. The overall dressing change operation is very difficult. In contrast, the present invention raises the support members at the head and tail of the bed body through electric push rods, leaving a certain gap between the middle of the patient's body and the bed surface. In this way, medical staff can more easily perform disinfectant spraying operations on the wound from the gap and replace dressings for individual small areas of the wound surface without pushing the patient to change the body position, minimizing the stretching and squeezing of the burn wound surface to the greatest extent, avoiding damage to the newly formed tissue and wound dehiscence, reducing the pain felt by the patient during dressing change, reducing secondary injuries caused by dressing change, providing a more comfortable and safe treatment experience for the patient, and facilitating better wound healing.

[0013] 2. Improve the dressing change efficiency. For patients with multiple burns on the front and back of the body, when medical staff remove the old dressings on the wound surface in contact with the bed surface of the patient, the torn dressings are directly on the bed sheet. Then, by relying on the roller to drag the bed sheet, the rapid replacement of the old dressings and the bed sheet together can be achieved, without the need to move the patient as in the existing technology to remove the old dressings, thus saving time and improving the dressing change efficiency.

[0014] 3. Reduce the dressing change difficulty. In the later stage of the repair phase of the burn wound, the wound surface is gradually repairing, and the wound skin. At this time, some ointments containing growth factors need to be applied. This solution can apply the ointment on the new gauze, and by adjusting the electric push rods to raise the support members at the head and tail of the bed body, a gap is left between the patient's wound surface and the bed surface. Medical staff place the gauze coated with the ointment in the gap between the patient's wound and the bed surface, and fix the gauze on the surface of the bed sheet with tape. Then, control the reel to drag the bed sheet, so that the bed sheet can drag the gauze to move, and the ointment on the gauze can be applied to the patient's surface. Without the patient having to significantly adjust the body position to expose the wound, the application of the ointment to the wound surface blocked by the bed surface can be achieved, reducing the dressing change difficulty and improving the dressing change efficiency.

[0015] 4. Promote wound healing and shorten the recovery time. For patients with multiple burns on the front and back of the body, the diagnostic beds of the prior art will press the wounds on the bed surface, resulting in the wound surface not being ventilated, which will increase the local temperature and humidity and is not conducive to the evaporation of wound moisture and the formation of scabs. This will cause the accumulation of wound exudate, making the wound surface in a wet state, affecting the proliferation of fibroblasts and the synthesis of collagen, thus delaying wound healing. At the same time, the long-term non-ventilation of the wound surface will increase the number of bacteria around the wound, easily causing wound infection. This requires the patient to change positions frequently. However, by adjusting the height of the support members at the head and tail of the bed body, the present invention creates a gap between the bed surface and the patient's wound surface, ventilates the wound, thereby avoiding wound infection, promoting wound healing, and shortening the recovery time.

[0016] 5. Reduce the risk of nursing dressing change and improve the efficiency of nursing work. Since the sheet replacement in the prior art requires the patient to completely leave the bed surface, which is likely to cause the risk of wound cracking and infection for burn patients. In this solution, the support members at the head and tail of the bed body are lifted by the electric push rod, causing the middle part of the patient's body to bend downward naturally. In this way, the stress points of the sheet are basically located at the middle part of the patient's body and the back of the heels. The contact area between the patient's body and the sheet is smaller. The medical staff can help the patient slightly lift the middle part of the body and pull out a section (or multiple sections according to the situation) of the sheet under the middle pad. At the same time, because the sheet adopts a repeatedly circuitous stacking method, after the sheet is pulled out, the unused surface of the sheet just lies flat on the bed body again. Then, by relying on the roller to wind the sheet, the sheet replacement can be easily achieved without the patient leaving the bed surface. Compared with the prior art, it can avoid the wound friction and tearing caused by the patient getting up and moving, greatly reducing the risk of infection and pain aggravation, and providing a safer nursing dressing change environment for the patient; in addition, compared with the prior art, this design can save the time for the patient to get up and transfer. The nursing staff can complete the operation within a few minutes, significantly improving the turnover efficiency of the hospital bed, especially suitable for the high-frequency sheet replacement requirements in the burn department, reducing the work intensity of the medical staff, and improving the work efficiency.

[0017] 6. Reduce the patient's psychological burden and contribute to wound recovery. Burn patients often have a fear of nursing operations due to physical trauma. This solution avoids the painful process of the patient getting up actively, reduces the patient's resistance and anxiety towards the sheet replacement operation, helps to establish the patient's trust in the medical staff, enhances the patient's enthusiasm for cooperating with the treatment, improves the overall medical experience. At the same time, in the prior art, the patient needs to get up to change the sheet, and the sheet replacement process is likely to interrupt the patient's rest. However, this solution avoids the patient's body movement, is beneficial to the patient's wound recovery, and shortens the recovery time.

[0018] 7. Improve the versatility and maintainability of the equipment. This bed sheet replacement solution is not only suitable for burn patients, but can also be extended to other patient groups with limited mobility and inconvenient to move frequently, such as orthopedic postoperative patients and elderly bedridden patients, which expands the application scope of the equipment and promotes the rational use of medical resources.

[0019] Furthermore, the sheet stacking mechanism includes a base plate, a back plate fixed on one side of the base plate, mounting plates symmetrically fixed on both sides of the back plate, a lead screw rotatably connected between the mounting plates, a slider threadedly connected to the lead screw, and a pair of rollers fixed on the slider, wherein the lead screw is driven by a servo motor fixed on one side of the mounting plate, a guide groove is provided on the back plate, and one end of the slider away from the pair of rollers is slidably connected in the guide groove, a winding drum is provided on the back plate, and unstacked sheets are wound on the winding drum, and one end of the sheet is led downward from between the pair of rollers.

[0020] Beneficial effects: With the help of a servo motor, the screw is driven to rotate, which drives the slider to move on the screw, and then the rollers are reciprocated. When the winding drum rotates, the sheets are formed into repeated and circuitous stacking shapes under the action of the rollers, which greatly improves the efficiency of sheet stacking and meets the needs of high-frequency sheet replacement in the burn department. The screw transmission has high precision and can accurately control the moving position and distance of the rollers. Combined with the guiding effect of the guide groove on the back plate on the slider, it ensures that the rollers maintain a stable and accurate trajectory during the movement, thereby ensuring that the shape of the stacked sheets is regular and neat, providing a good foundation for subsequent sheet replacement operations.

[0021] Furthermore, the bottom plate is symmetrically provided with rotary pressing cylinders, and the middle pad can be placed between the rotary pressing cylinders.

[0022] Beneficial effects: The middle pad can receive the stacked sheets. After the sheets are stacked, the middle pad and the sheets can be directly replaced on the bed body as a whole, which improves the replacement efficiency. During the sheet stacking process, the rotating pressing cylinder can press the two ends of the sheets to prevent the sheets from shifting, sliding or wrinkling during the reciprocating stacking of the rollers. Especially when the sheets are made of slippery materials or there are many layers of stacking, the pressing cylinder can ensure that the sheets always remain in the predetermined position to ensure the regularity of the stacking shape.

[0023] Furthermore, the support member includes a headboard and a footboard, and a pillow is arranged above the headboard.

[0024] Beneficial effects: The headboard and footboard serve as supporting parts, and cooperate with the electric push rod under the bed body to lift the headboard and footboard, so that the middle part of the patient's body can be bent downward, reducing the contact area between the patient and the bed sheet. Medical staff can easily pull out the stacked sheets under the middle pad, realizing the convenient operation of replacing the sheets.

[0025] Furthermore, a mounting hole is provided in the middle of the bed, the middle pad is located in the mounting hole, an electric cylinder is provided under the middle pad, the electric cylinder is fixed on the bracket, a top plate is fixed on the top of the piston rod of the electric cylinder, and the upper surface of the top plate forms a support for the bottom of the middle pad.

[0026] Beneficial effects: The electric cylinder can drive the middle cushion to rise and fall, and cooperate with the electric push rod to lift the headboard and footboard, so as to adjust the height difference between the middle cushion and the headboard and footboard. The degree of curvature of the patient's body can be adjusted according to the different performance of different patients, which improves the convenience of changing bed sheets. The electric cylinder drives the middle cushion downward, which is also convenient for medical staff to directly replace the stacked sheets from under the bed, further improving the convenience of operation.

[0027] Furthermore, the sheet stacking mechanism is located on one side of the bed body, and the sheet stacking mechanism also includes a feeding mechanism, which includes an electric telescopic rod fixed on the back plate, and a push plate is provided at the end of the push rod of the electric telescopic rod, and the push plate is used to push the middle pad on the bottom plate onto the top plate.

[0028] Beneficial effect: When the unstacked sheets on the back plate are stacked, the electric telescopic rod drives the push plate to automatically push the middle pad on the bottom plate to the top plate, without the need for medical staff to manually carry it. Especially in continuous care scenarios, the replacement and replenishment of the middle pad can be completed quickly, making the entire sheet preparation process automated, greatly shortening the preparation time before care, and improving the turnover efficiency of hospital beds.

[0038] Embodiment 1

[0039] As Figures 1 to 7 shown, a device for burn dressing change includes a bracket 1, a bed body 2 fixed on the bracket 1, and a replacement unit for replacing the bedsheet 6.

[0040] As Figure 1 shown, support members are provided at the head and tail of the bed body 2. The support members include a headboard 4 and a footboard. A pillow cushion 3 is arranged above the headboard 4. An intermediate cushion 5 is provided in the middle of the bed body 2. A plurality of electric push rods 11 are provided below the bed body 2. The electric push rods 11 are respectively located below the headboard 4 and the footboard, and the electric push rods 11 can lift the headboard 4 and the footboard to a certain height.

[0041] As Figure 1 and Figure 2 shown, the replacement unit includes a bedsheet replacement mechanism and a bedsheet stacking mechanism. The bedsheet replacement mechanism includes a roller 9 and a guide roller 8 fixed at the tail end of the bed body 2. A roller groove 10 fixed to the bracket 1 is arranged outside the roller 9. The rotating shafts at both ends of the roller 9 are rotatably connected in the roller groove 10. One end of the rotating shaft of the roller 9 is connected to a motor, and the motor is used to drive the roller 9 to rotate in the roller groove 10. The guide roller 8 is located at the tail end of the bed body 2. Mounting lugs are provided on both sides of the tail end of the bed body 2, and the guide roller 8 is rotatably connected between the mounting lugs.

[0042] As Figure 4 and Figure 5As shown, the sheet stacking mechanism includes a bottom plate 20, a back plate 12 vertically fixed to the inner side of the bottom plate 20, mounting plates 151 symmetrically fixed to the left and right sides of the back plate 12, a lead screw 14 rotatably connected between the mounting plates 151, a slider 17 threadedly connected to the lead screw, and a pair of rollers 18 fixed to the slider 17. The lead screw is driven by a servo motor 15 fixed to one side of the mounting plate 151. A guide groove 141 is transversely provided on the back plate 12. One end of the slider 17 away from the pair of rollers 18 is slidably connected in the guide groove 141. A winding drum 13 is provided on the back plate 12. A driving motor 21 is provided on the back plate 12. The main shaft of the driving motor 21 is connected to the central axis of the winding drum 13 through a coupling 19. The winding drum 13 is wound with unstacked sheets 6, and one end of the sheets 6 is led downward from between the pair of rollers 18. Rotating pressing cylinders 16 are symmetrically provided on the bottom plate 20, and the middle pad 5 can be placed between the rotating pressing cylinders 16. The present invention also includes a PLC controller and a switch button. The PLC controller is electrically connected to the driving motor 21, the servo motor 15, the electric push rod 11, the electric cylinder 24, the rotary pressing cylinder 16 and the motor for driving the roller 9 to rotate and other electric drive components in this solution.

[0043] like Figure 4 As shown, the sheet stacking mechanism is used to fold new sheets. The sheets of this technology are disposable sheets, and the working process is as follows: the unstacked sheets 6 are placed on the winding drum 13. The winding drum 13 rotates under the drive of the driving motor 21, and the sheets 6 fall down from between the rollers 18. The gap between the two rollers 18 is greater than the thickness of the sheets 6. The servo motor 15 drives the screw rod to rotate back and forth, so that the slider 17 slides horizontally in the guide groove 141, so that while the sheets 6 fall, the rollers 18 also guide the sheets 6 back and forth. After the bed sheet 6 falls onto the middle pad 5 below, the bed sheet 6 is naturally stacked into a repeated and circuitous stacking shape; and in order to prevent the bed sheet 6 from deviating during the stacking process, each time the slider 17 moves to the two ends, the pressure head of the rotary pressing cylinder 16 rotates to avoid first, and after each bend of the bed sheet 6, the rotary pressing cylinder 16 rotates again to press the two ends of the bed sheet 6, ensuring that the bed sheet 6 always remains in the predetermined position and the regularity of the stacking shape is guaranteed; and the stacked bed sheet 6 is automatically located above the middle pad 5, and the medical staff can replace the entire middle pad 5 to Figure 1 The sheet 6 is placed on the bed 2 in the middle, and one side of the sheet 6 is wound around the guide roller 8 and wound onto the roller 9 at the rear end of the bed 2. The stacked sheet 6 is as shown in FIG. Figure 3 As shown, the advantage of this stacking is that the contact surface 601 is always kept at the top, and the pre-contact surface 602 is in a relative state. When the contact surface 601 of the sheet 6 is pulled to the right, the pre-contact surface 602 can be quickly unfolded to form a new contact surface 601, and the replacement time is very fast.

[0044] The usage of this device is as follows:

[0045] The sheet 6 is pre-folded by Figure 4 the sheet stacking mechanism in, and the optimal placement position of the sheet stacking mechanism is inside the long side of the bed body 2 in Figure 1 . In this way, the sheet 6 folded by the sheet stacking mechanism can ensure that its direction is the same as the direction when it is placed on the bed body, which is convenient for replacing the sheet 6; as Figure 1 shown, when the patient lies above the bed body 2 and the medical staff performs nursing and dressing changes on the patient, it is usually necessary to replace the sheet 6. At this time, the corresponding electric push rod 11 can be controlled by the remote control switch button to lift the headboard 4 and the footboard to a certain height, so that the middle part of the patient's body bends downward naturally and becomes Figure 2 a certain state. In this way, the stress points of the sheet 6 are basically located in the middle part of the patient's body and the back of the legs. Compared with Figure 1 the lying state in, the contact area 601 between the patient's body and the sheet 6 is smaller, and the sheet 6 is easier to be pulled. In this way, the medical staff can help the patient slightly lift the middle part of the body, first pull out a section or multiple sections of the sheet 6 above the middle pad 5 according to the situation. Since the sheet 6 adopts a repeatedly circuitous stacking method, after the sheet 6 is pulled out, Figure 3 the pre-contact surface 602 in just forms a new contact surface 601 and is re-laid on the bed body 2. Then, the remote control switch is used to start the roller 9 to wind the used sheet 6, and the patient is asked to gently lift the legs, and the used contact surface 601 on the sheet 6 can be wound away by the roller 9. In this way, the replacement of the sheet 6 can be easily realized without the patient leaving the bed surface. Compared with the prior art, it can avoid wound friction and tearing caused by the patient getting up and moving, greatly reducing the risk of infection and pain aggravation, and providing a safer nursing and dressing change environment for the patient; the pillow cushion 3 at the head of the bed can also be replaced separately. Compared with the prior art, this design can save the time for the patient to get up and transfer. The nursing staff can complete the operation within a few minutes, significantly improving the turnover efficiency of the hospital bed, especially suitable for the high-frequency sheet 6 replacement requirements in the burn department, reducing the work intensity of the medical staff and improving the work efficiency.

[0046] For severely burned patients, especially those with multiple burns on the front and back of the body, the present invention raises the support members at the head and tail of the bed body 2 through the electric push rod 11, leaving a certain gap between the middle of the patient's body and the bed surface. In this way, medical staff can more easily spray disinfectant on the wound from the gap and change dressings for individual small areas of the wound surface without having to move the patient to change positions, minimizing the pulling and squeezing of the burn wound, avoiding damage to newly formed tissues and wound dehiscence, reducing the pain felt by the patient during dressing change, reducing secondary injuries caused by dressing change, providing a more comfortable and safe diagnosis and treatment experience for the patient, and facilitating better wound healing. In addition, when medical staff remove the old dressing on the wound surface in contact with the bed surface of the patient, the torn dressing is directly located on the bed sheet 6. Then, by relying on the roller 9 to drag the bed sheet 6, the quick replacement of the old dressing and the bed sheet 6 together can be achieved, without having to move the patient to remove the old dressing as in the prior art. Therefore, time is saved and the dressing change efficiency is improved. In the later stage of the repair phase of the burn wound, the wound surface is gradually repairing, and the wound skin. At this time, some growth factor-containing ointments need to be applied. This solution can apply the ointment on the new gauze, and by adjusting the electric push rod 11 to raise the support members at the head and tail of the bed body 2, a gap is left between the patient's wound surface and the bed surface. Medical staff pad the gauze coated with the ointment in the gap between the patient's wound and the bed surface, and fix the gauze on the surface of the bed sheet 6 with tape. Then, by controlling the reel to drag the bed sheet 6, the bed sheet 6 can drag the gauze to move, so that the ointment on the gauze is applied to the patient's surface. Without having to let the patient greatly adjust the position to expose the wound, the dressing of the wound surface blocked by the bed surface can be achieved, reducing the difficulty of dressing change and improving the dressing change efficiency.

[0047] Embodiment 2

[0048] The difference between this embodiment and Embodiment 1 is that, as Figure 6 shown, there is also an installation hole in the middle of the bed body 2. The middle pad 5 is located in the installation hole. An electric cylinder 24 is provided below the middle pad 5. The electric cylinder 24 is fixed on the bracket 1. The top end of the piston rod of the electric cylinder 24 is fixed with a top plate 241, and the upper surface of the top plate 241 supports the bottom of the middle pad 5. The electric cylinder 24 can drive the middle pad 5 to move up and down. Cooperating with the electric push rod 11 to lift the headboard 4 and the footboard, the height difference between the middle pad 5 and the headboard 4 and the footboard can be adjusted, and the bending degree of the patient's body can be adjusted according to the body types of different patients, improving the convenience during the replacement of the bed sheet 6. When the electric cylinder 24 drives the middle pad 5 to move downward, it is also convenient for medical staff to directly replace the stacked bed sheet 6 from below the bed body 2, further improving the operation convenience.

[0049] Embodiment 3

[0050] The difference between this embodiment and Embodiment 2 is that, as Figure 7As shown in the figure, the sheet stacking mechanism is arranged on one side of the bed body 2. The sheet stacking mechanism further includes a feeding mechanism. The feeding mechanism includes an electric telescopic rod 22 fixed on the back plate 12. The push rod 23 of the electric telescopic rod 22 passes through the back plate 12, and a push plate is provided at the end of the push rod 23. When the sheets 6 are stacked and drawn out, the electric telescopic rod 22 can drive the push plate to push the intermediate pad 5 from the bottom plate 20 onto the top plate 241. Then, the electric cylinder 24 pushes the top plate 241 upward to push the entire intermediate pad 5 into the mounting hole of the bed body 2, realizing automatic replacement of the intermediate pad 5 without manual handling by medical staff. Especially in the continuous care scenario, the replacement and replenishment of the intermediate pad 5 can be quickly completed, making the entire sheet 6 preparation process automated, greatly shortening the preparation time before nursing, and improving the turnover efficiency of hospital beds.
