Description

Technical Field

[0001] The present invention relates to the field of palliative care, and in particular to a multifunctional palliative care system. Background Art

[0002] Palliative care refers to the practice of a multidisciplinary collaborative model centered on terminally ill patients and their families, providing patients with physical, psychological, spiritual care and humanistic care services.

[0003] In order to meet hygiene requirements, bed sheets need to be changed frequently to avoid infection and ensure the comfort of patients. When changing bed sheets for bedridden patients, it mainly includes:

[0004] 1. Stand on one side of the bed and help the patient turn over and lie on his side on the bed board on the opposite side. Loosen the half of the sheet on the near side and roll it up behind the patient. Then spread the clean sheet on the bed board on this side and roll up the other side of the clean sheet behind the patient.

[0005] 2. Assist the patient to turn over and lie on his side on the near-side bed board, move to the opposite side of the bed, remove the dirty bed sheet on the opposite side of the bed board, unfold the curled clean bed sheet, and lay it on the opposite side of the bed board;

[0006] 3. Turn the patient over and lay him flat in the middle of the bed.

[0007] In the process of changing the bed sheet of a bedridden patient, since the patient is in bed, it is necessary to turn the patient over and change the bed sheet, and the bed sheet can only be changed half by half. The whole process is troublesome, the workload of medical staff is heavy, and the changing efficiency is low. Summary of the invention

[0008] The present invention is intended to provide a multifunctional palliative care system to solve the current problems of heavy workload and low replacement efficiency when replacing bed sheets for bedridden patients.

[0009] In order to achieve the above object, the present invention adopts the following technical scheme:

[0010] A multifunctional palliative care system includes a hospital bed and slide rails arranged at the head and foot of the bed, the slide rails are arranged along the width direction of the hospital bed, two fixed seats are slidably connected to the slide rails, and the fixed seats are detachably connected to the slide rails; two reels are rotatably arranged on both sides of the fixed seats, and the reels are connected to reel stepper motors, and when the fixed seats are installed on the slide rails, the axial direction of the reels is consistent with the length direction of the hospital bed, clamping grooves are opened on the opposite sides of the two reels, and clamping components are arranged in the clamping grooves, and notches are opened on both sides of the fixed seats, and the notches are connected to the clamping grooves.

[0012] Preferably, as an improvement, the reel stepper motor is electrically connected to a controller, a switch slot is provided on the fixed seat, a motor switch is hinged in the switch slot, a first pressure sensor is installed at one end of the switch slot, and a second pressure sensor is installed at the other end of the switch slot, the two ends of the motor switch can trigger the first pressure sensor and the second pressure sensor respectively, the first pressure sensor and the second pressure sensor are both electrically connected to the controller, when the motor switch triggers the first pressure sensor, the controller controls the reel stepper motor to rotate forward; when the motor switch triggers the second pressure sensor, the controller controls the reel stepper motor to reverse; when both the first pressure sensor and the second pressure sensor are not triggered, the controller controls the reel stepper motor to stop rotating.

[0013] Preferably, as an improvement, a widened section is provided in the middle of the slide rail, and the widened section protrudes horizontally toward the outside of the bed.

[0014] Preferably, as an improvement, the reel comprises a connecting section and a winding section, the diameter of the winding section is smaller than that of the connecting section, and the connecting section is rotatably connected in the fixing seat.

[0015] Preferably, as an improvement, a positioning rod is vertically threadedly connected to the fixing seat, and a positioning hole for cooperating with the positioning rod is provided on the slide rail.

[0016] Preferably, as an improvement, a storage groove is provided on the headboard of the hospital bed, a support plate is rotatably connected in the storage groove, the support plate is connected to a support plate stepper motor, the support plate stepper motor is electrically connected to the controller, after the first pressure sensor is triggered, the controller also controls the support plate stepper motor to drive the support plate to rotate out; a proximity switch for monitoring the fixed seat is installed at the widening section, the proximity switch is electrically connected to the controller, when the proximity switch detects the fixed seat, the controller controls the support plate stepper motor to drive the support plate to rotate back into the storage groove.

[0017] The principles and beneficial effects of this scheme are:

[0018] 1. This solution can assist medical staff to roll up dirty sheets and clean sheets behind the patient after the patient turns over, and at the same time lay the clean sheets on the bed with the rolled dirty sheets, reducing the workload of medical staff and improving the efficiency of changing sheets. Specifically: In the initial state, the two fixed seats on a slide rail are located at both ends of the slide rail, and the two ends of the old sheets are respectively stuck in the two fixed seats. When changing the left bed sheet, turn the patient over to the right bed board, and fix the right side of the clean sheet between the two fixed seats at the head and foot of the left bed board. The reel stepper motor drives the reel that clamps the clean sheet to rotate and roll up the right half of the clean sheet into a roll for standby use, and then manually slide the fixed seat on the left bed behind the patient. During the sliding process, the old sheets are stacked behind the patient, and at the same time, the fixed seat drives the unrolled half of the clean sheet to be laid on the left bed, thereby completing the replacement of the sheets on the left bed. To replace the right-side bed, turn the patient over to the left-side bed, start the scroll stepper motor to reverse and release the clean sheet, then continue to slide the fixed seat until it reaches the right edge of the bed, then unfold the clean sheet and lay it on the right side of the bed, and then remove the dirty sheet. It is simple to operate and easy to replace.

[0019] 2. This solution sets slide rails at the head and foot of the bed, and sets two fixing seats on the slide rails. The two fixing seats are slid to the two ends of the slide rails. The four corners of the bed sheet are clamped with the fixing seats at ordinary times. This not only facilitates the subsequent replacement of the bed sheet, but also effectively prevents the bed sheet from shifting.

[0020] 3. After putting the bed sheet into the clamping groove, press the electromagnet switch to energize the electromagnet. The energized electromagnet will adsorb the clamp block and clamp stably.

[0021] 4. In this solution, the motor switch is hinged on the fixed seat. When the motor switch is pressed toward one end of the switch slot, the first pressure sensor is triggered. At this time, the controller controls the reel stepper motor to rotate forward to realize the winding of the clean bed sheet. When the motor switch is pressed toward the other end of the switch slot, the second pressure sensor is triggered. At this time, the controller controls the reel stepper motor to reverse and release the clean bed sheet. During operation, you only need to press the switch as needed. The operation is simple.

[0022] 5. In the present solution, an outwardly protruding widening section is arranged in the middle of the slide rail. When the fixed seat moves to the widening section, the distance between the two fixed seats at the head and foot of the bed increases, thereby being able to tighten the sheets clamped between the two fixed seats, so that the rolled clean sheets and the folded dirty sheets are stretched tight. After being stretched, the rolled sheets are tighter and fit the bed more closely, reducing obstacles to the patient's turning over and making it easier to turn over. At the same time, it can also effectively prevent the patient from pressing on the rolled sheets when turning over.

[0023] 6. In this solution, a positioning rod is provided on the fixing seat, a positioning hole is provided on the slide rail, and the fixing seat can be fixed by inserting the positioning rod into the positioning hole.

[0024] 7. This solution also has a support plate that is rotatably set on the headboard. When the motor switch is pressed and the first pressure sensor is triggered, the controller not only controls the reel to reel in the clean bed sheet, but also controls the supporting stepper motor to drive the support plate to rotate behind the patient to support the patient, ensuring that the patient remains in a side-lying position during the process of changing the bed sheet, without affecting the replacement of the bed sheet; when the sliding widening section of the fixed seat is detected by the proximity switch, the controller controls the support plate to rotate back into the storage slot, making it convenient to turn the patient back later.

[0037] Embodiment 1:

[0038] like Figure 1 and Figure 2 As shown, a multifunctional palliative care system includes a hospital bed 1 and a slide rail 3. The hospital bed 1 includes a bed frame 11, on which a bed board 12 is laid. There is a gap between the bed board 12 and the headboard and footboard. The slide rail 3 is installed in the gap. The headboard and footboard are each installed with a slide rail 3 along the width direction of the hospital bed 1. The middle part of the slide rail 3 horizontally protrudes toward the outside of the hospital bed 1 to form a widening section 31. Two fixing seats 4 are slidably connected to each slide rail 3, that is, a total of four fixing seats 4, Figure 1 The fixing seat 4 shown in FIG. 1 is named as fixing seat 4 No. 1. Figure 2 The remaining three fixing seats 4 shown in the figure are No. 2 fixing seat 4, No. 3 fixing seat 4 and No. 4 fixing seat 4 in clockwise order. The fixing seats 4 can be removed from both ends of the slide rail 3 and combined with Figure 3 As shown, a positioning rod 41 is vertically threadedly connected to the fixing seat 4, and positioning holes for cooperating with the positioning rod 41 are opened at both ends of the slide rail 3. The fixing seat 4 can be fixed on the slide rail 3 by screwing the positioning rod 41 into the positioning hole. After the positioning rod 41 is screwed out of the positioning hole, the fixing seat 4 can slide on the slide rail 3.

[0039] Combination Figure 3 and Figure 5 As shown, a reel 44 is rotatably installed in both the left and right sides of the fixed seat 4. The reel 44 includes a connecting section 443 and a winding section 442. The diameter of the winding section 442 is smaller than the diameter of the connecting section 443. The connecting section 443 is rotatably connected in the fixed seat 4. The connecting section 443 is connected to a reel stepping motor. A clamping groove 441 is opened on the winding section 442 on the opposite side of the two reels 44. A notch 45 is opened on the left and right sides of the fixed seat 4. The notch 45 is connected to the clamping groove 441. A clamping assembly is installed in the clamping groove 441, which is combined with the clamping assembly. Figure 6As shown, the clamping assembly includes an electromagnet 444 and a clamping block 446 that can be adsorbed by the electromagnet 444. The electromagnet 444 is glued and fixed at the bottom of the clamping groove 441. The clamping block 446 is slidably connected to the top of the clamping groove 441. The clamping block 446 is connected to a reset spring 445 for driving the clamping block 446 to reset. An electromagnet switch 42 for controlling the power on and off of the electromagnet 444 is installed on the fixing seat 4. The electromagnet switch 42 is a push-type switch, similar to the light switch in the prior art. When pressed, the electromagnet 444 is energized, and when pressed again, the electromagnet 444 is de-energized.

[0040] The scroll stepper motor is electrically connected to a controller, combined with Figure 4 As shown, a switch slot 431 is provided on the fixing seat 4, a motor switch 43 is hinged in the switch slot 431, a first pressure sensor 432 is installed at one end of the switch slot 431, and a second pressure sensor 433 is installed at the other end of the switch slot 431, and the two ends of the motor switch 43 can trigger the first pressure sensor 432 and the second pressure sensor 433 respectively, and the first pressure sensor 432 and the second pressure sensor 433 are both electrically connected to the controller. When the motor switch 43 triggers the first pressure sensor 432, the controller controls the reel stepper motor to rotate forward; when the motor switch 43 triggers the second pressure sensor 433, the controller controls the reel stepper motor to rotate reversely; when the first pressure sensor 432 and the second pressure sensor 433 are not triggered, the controller controls the reel stepper motor to stop rotating. In this embodiment, an electromagnet switch 42 is correspondingly provided for each electromagnet 444 in the clamping slot 441, and a motor switch 43 is also correspondingly provided for each reel 44, so that each electromagnet 444 and each reel 44 can be controlled separately. All the electromagnet switches 42 and motor switches 43 are mounted on the fixing base 4 and are marked with corresponding marks for the convenience of the operator to distinguish them in actual use. The accompanying drawings show one electromagnet switch 42 and one motor switch 43 respectively.

[0041] A method of using a multifunctional palliative care system is as follows:

[0042] During daily use, the two fixing seats 4 on the same slide rail 3 are respectively located at the two ends of the slide rail 3. After the bed sheet is laid, the four corners of the bed sheet are respectively fixed on the four fixing seats 4, which can achieve the effect of fixing the bed sheet.

[0043] When changing bed sheets, the following steps are involved:

[0044] 1. Assist the patient to turn over to the right and lie on the right side of bed 1: hold up the patient's head with one hand, move the pillow to the right side of bed 1 with the other hand, cross the patient's upper limbs in front of the chest, and then move the left lower limb to the right limb. Figure 7 In the manner shown, one hand is placed under the patient's shoulder and the other hand is placed under the buttocks, and the patient is placed on the right side of the bed 1, that is, Figure 8 Status shown.

[0045] 2. Fix the clean bed sheet 5: Take a clean bed sheet 5, and put the two right corners of the clean bed sheet 5 into the two fixing seats 4 of No. 1 and No. 4 respectively. After inserting, press the left side of the fixing seats 4 of No. 1 and No. 4 ( Figure 3 (middle perspective) The electromagnet switch 42 corresponding to the reel 44, when the electromagnet 444 is energized, attracts the clamping block 446, and the clamping block 446 clamps the bed sheet, and the right side of the clean bed sheet 5 is fixed.

[0046] 3. Roll up the right clean bed sheet 5: press the upper end of the motor switch 43 on the No. 1 and No. 4 fixed seats 4 for controlling the left reel 44, the motor switch 43 triggers the first pressure sensor 432, the first pressure sensor 432 sends a signal to the controller, the controller controls the reel stepper motor to drive the reels 44 clamping the clean bed sheet 5 in the No. 1 and No. 4 fixed seats 4 to rotate forward at the same time, thereby rolling up the right side of the clean bed sheet 5 into a roll.

[0047] 4. Fold the dirty bed sheet 2 on the left side and lay the clean bed sheet 5 on the left side: Manually slide the No. 1 and No. 4 fixing seats 4 behind the patient, so that the left part of the clean bed sheet 5 is laid on the left bed 1. At the same time, because the right part of the dirty bed sheet 2 is pressed under the patient and the left side is fixed in the fixing seat 4, when the fixing seat 4 slides behind the patient, the dirty bed sheet 2 between the fixing seat 4 and the patient is folded up, that is, Fig. 9 The state shown, whereby the left sheet has been replaced.

[0048] 5. Replace the right bed sheet: Assist the patient to turn over to the left and lie on the left side of the bed 1, ensuring that the rolled clean bed sheet 5 and the folded dirty bed sheet 2 are located behind the patient. The turning method is the same as step 1. Press the lower end of the motor switch 43 of the reel 44 clamping the clean bed sheet 5 on the No. 1 and No. 4 fixing seats 4, and the motor switch 43 triggers the second pressure sensor 433. The second pressure sensor 433 sends a signal to the controller, and the controller controls the reel stepper motor to drive the reel 44 to rotate in the opposite direction, releasing the rolled clean bed sheet 5. Manually slide the No. 1 and No. 4 fixing seats 4 to the right to the right edge of the bed 1, thereby laying the rolled clean bed sheet 5 on the right side of the bed 1. Remove the dirty bed sheet 2 from the No. 1 and No. 4 fixing seats 4, and then remove the No. 2 and No. 3 fixing seats 4 originally located on the right edge of the bed 1 from the dirty bed sheet 2, and install them on the left side of the left side of the bed 1 clamping the clean bed sheet 5, thereby completing the laying of the clean bed sheet 5.

[0049] In this embodiment, the middle part of the slide rail 3 protrudes outward to form a widened section 31. When the fixing seat 4 slides to the widened section 31, the distance between the two fixing seats 4 at the head and foot of the bed is increased, thereby tightening the rolled clean bed sheet 5 and the folded dirty bed sheet 2, so that the bed sheet fits the bed 1 better. When the patient turns over, he can better pass over the rolled clean bed sheet 5 without taking the clean bed sheet 5 away, and the rolled clean bed sheet 5 can be prevented from being pressed under the patient.

[0050] Embodiment 2:

[0051] like Fig.10 As shown, the difference between this embodiment and embodiment 1 is that a storage slot 6 is provided on the headboard of the bed 1, and a support plate 61 is rotatably connected in the storage slot 6, and the support plate 61 is connected to a support plate stepper motor, and the support plate stepper motor is electrically connected to the controller. After the first pressure sensor 432 is triggered, the controller also controls the support plate stepper motor to drive the support plate 61 to rotate out behind the patient. A proximity switch for monitoring the fixing seat 4 is installed at the widening section 31, and the proximity switch is electrically connected to the controller. When the proximity switch detects the fixing seat 4, the controller controls the support plate stepper motor to drive the support plate 61 to rotate back into the storage slot 6. That is, when the clean bed sheet 5 is rolled up, the support plate 61 rotates behind the patient to support the patient's back, which can help the patient to maintain a side-lying state; when the fixing seat 4 slides to the widening section 31, it is detected by the proximity switch, and the proximity switch sends a signal to the controller, and the controller controls the support plate stepper motor to drive the support plate 61 to rotate in the opposite direction, so that the support plate 61 rotates back into the storage slot 6 for storage, which is convenient for the subsequent turning of the patient.

[0052] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
