DETAILED DESCRIPTION
[0035] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0036] Example
[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9 As shown, a fall-proof and pressure-ulcer-proof medical bed comprises a bed body 2, on which an actuation system 1 is arranged, the actuation system 1 comprises an anti-pressure-ulcer actuator assembly 11, anti-fall actuator assemblies 12 are arranged on both sides of the anti-pressure-ulcer actuator assembly 11, a wiring harness 13 is arranged on the lower sides of the anti-pressure-ulcer actuator assembly 11 and the anti-fall actuator assembly 12, an identification area 21 is arranged on the bed body 2, a control computer 22 is installed on the bed body 2, a bottom plate 23 is connected to the bed body 2, a wiring harness passage 24 is arranged on the bottom plate 23, and the wiring harness 13 is connected to the control computer 22 after passing through the wiring harness passage 24.
[0038] like Figure 4 As shown, the bed body is composed of an identification area 21, a control computer 22, a bottom plate 23, and a harness passage 24. The identification area 21 is designed on the lateral side of the bed body 2, and the anti-pressure sore actuator 113 of the actuation system 1 corresponds to each other in both directions. For example, the longitudinal direction can be marked with "1, 2, 3, 4...", and the transverse direction can be marked with "A, B, C, D...". In this way, each anti-pressure sore actuator 113 can be positioned by the longitudinal and transverse markings, which is convenient for designing in the program of the control computer 22. For example, "5C" represents the fifth longitudinal actuator 113 that intersects with the transverse marking C, which is convenient for nursing staff to set the sinking block 114 on the control computer, especially for patients after surgery, it is convenient to find the actuator 113 that needs to be sunk according to the marking of the identification area and the position of the patient's wound. The control computer 22 is the core of the whole system. The actuator 113 is controlled by the control computer 22. The actuator 113 in the actuator system 1 moves to meet the functions of preventing falls and pressure sores. Different control programs can be designed inside the control computer 22. For different types of patients and patients with different symptoms, reasonable control programs can be designed to control the movements of the anti-pressure sore actuator and the anti-fall actuator to achieve the ultimate control goal and function. At the same time, the control computer 22 can control the sinking block 114 of the anti-pressure sore actuator to slow down as much as possible when it is about to touch the human body, and maintain a basically non-sensitive state. When the patient is asleep, it can still be used to improve the patient's feeling. The bottom plate 23 fixes and supports the actuator to ensure the flatness of the bed surface, and at the same time connects the bed frame of the bed body 2. More holes are designed on the bottom plate 23 for the connecting bolts at the lower part of the actuator to pass through, and are fixed at the lower part of the bottom plate 23. The wiring harness passage 24 connects the control computer 22 and the wiring harness 13, which is the wiring channel of the wiring harness 13.
[0039] like Figure 5As shown, the actuation system is composed of an anti-pressure sore actuator assembly 11, an anti-fall actuator assembly 12, a harness 13 and a nut 14. The anti-pressure sore actuator assembly 11 is composed of a separate anti-pressure sore actuator cylinder 113. Each anti-pressure sore actuator cylinder 113 is independently controlled and is arranged side by side to form the main support surface of the anti-pressure sore medical bed. Sheets and mattresses can be laid on the actuation system 1 for patients to use. Each movement of the actuator cylinder 113 is sinking, which will not cause wrinkles on the upper sheets and mattresses. After rising, it returns to its original position, and the human body feels gentle. Each actuator cylinder 113 can control the speed of movement, which can improve the patient's body sensation. When the patient is sleeping soundly, The anti-fall actuator assembly 12 controls the tilting of the anti-fall plate 121 on the upper part of the tilting actuator 123 to prevent falling. The wiring harness 13 is connected to each actuator to supply power and provide control signals to the actuator to control the movement of the actuator. The nut 14 is threadedly connected to the connecting stud 115 of the actuator at the lower part of the bottom plate of the bed to fix the actuator on the bottom plate. The connection with the nut 14 has better maintainability. When an actuator fails, the failed actuator can be replaced by removing the nut 14 at the bottom. The anti-pressure sore actuator is an electrically controlled linear actuator cylinder 113, which can accurately control the stroke and rate of movement.
[0040] like Figure 6 and Figure 7 As shown, the anti-fall actuator assembly 12 is composed of an anti-fall plate 121, a plurality of fixed actuator cylinders 122 and a tilting actuator 123. In this example, there are four. An ear piece is designed at the lower part of the anti-fall plate 121 to connect with the fixed actuator cylinder 122 and the tilting actuator 123, and can rotate around the hole of the ear piece to realize the tilting of the anti-fall plate 121. The principle of the fixed actuator cylinder 122 and the tilting actuator 123 is similar to that of the anti-pressure sore actuator, and the control function is realized by the extension and shortening of the actuator. An ear piece is connected to the base of the rotary actuator and is connected through an axis. When extended, it pushes the outer side of the anti-drop plate 121 to move upward. The fixed actuator cylinder 122 and the tilting actuator 123 should not be designed too many or too few. If there are too many, each ear piece hole needs to be on the same straight line. Due to the processing tolerance, it is difficult to be collinear. If there are too few, the support for the anti-drop plate 121 is less and the rigidity is weaker. When the anti-drop plate 121 is subjected to force, it deforms greatly and cannot play an anti-drop effect. Generally, 3-4 are preferred.
[0041] like Figure 8 As shown, the wiring harness 13 is composed of a power line 131 and a signal line 132. The power line 131 supplies power to each actuator, and the signal line 132 controls the movement of each actuator. The power line 131 and the signal line 132 are arranged separately, and each power line 131 and signal line 132 are connected to the controllers on both sides. In this way, a row of actuators are separated between the power line 131 and the signal line 132, which can avoid interference of the power line 131 on the signal line 132, thereby ensuring higher accuracy of actuator control.
[0042] like Fig. 9 As shown, the wiring harness 13 is connected to the control computer 22 and the power supply line inside the bed 2 through the wiring harness passage 24 on the bed 2, so that the bed 2 is kept clean and tidy, and the wiring harness 13 is easy to check during maintenance.
[0043] like Fig.10 As shown, the anti-pressure sore actuator assembly 11 is mainly composed of a base 111, a fixed end 112, an actuator cylinder 113, a sinker 114, and a connecting stud 115. The base 111 is fixed to the fixed end 112, and the connecting stud 1156 is fixed to the fixed end 112 as a whole. The sinker 114 is fixed on the actuator cylinder 113 and moves with the up and down movement of the actuator cylinder 113. The sinker 114 is preferably made of a softer material to improve the human body's feeling. It can be made of wood, plastic, or rubber, and is preferably made of rubber. The actuator cylinder 113 is a straight rod that moves up and down and is connected to the fixed end 112. The actuator cylinder 113 is driven to move up and down by the movement of the motor and screw inside the fixed end. A control motor and mechanism are designed inside the fixed end 112, which moves through electric energy and the control signal given by the control computer 22 to control the movement of the actuator.
[0044] like Fig.11 and 12 As shown, the connecting studs 15 at the lower parts of the anti-pressure sore actuator 11 and the anti-fall actuator 12 pass through the holes of the bottom plate 23 , penetrate to the bottom of the bed body 2 , and are connected by nuts 14 .
[0045] like Fig.13 As shown, for patients who are bedridden for a long time, since they cannot move, the anti-fall function is not used, and only the anti-pressure sore function is used. To avoid pressure sores, the nursing staff sets the program according to their condition, sets the number of sinking blocks 114 each time, such as 3 blocks, sets the time after each sinking, such as 10 minutes, and then sets the sinking rules, such as sequential sinking, random sinking, sinking from both ends toward the middle, and sinking of sinking blocks 114 in multiple areas. The equipment is started to sink a part of the area so that the human body in this part is not subjected to pressure. After rising, other areas are sunk, and this cycle is repeated to achieve the purpose of preventing patients from developing pressure sores, while reducing the nursing burden of nursing staff.
[0046] like Fig.14 As shown, for patients who have just undergone surgery or elderly patients, according to the position of the patient lying on the bed and the position of the surgical wound, the actuator of the wound position is found on the control computer 22 according to the identification area 21 of the bed body 2, and the number of sinking blocks is confirmed according to the size of the wound. At the same time, according to the status of the surrounding accompanying personnel, it is confirmed whether to activate the anti-fall plate, start the equipment, and the area where the patient's wound is located sinks so that the wound position is not squeezed, thereby reducing the patient's pain.
[0047] When in use, for patients who have been bedridden for a long time, since they cannot move, the anti-fall function is not used, and only the anti-pressure sore function is used. To avoid pressure sores, the nursing staff sets the program according to their condition, sets the number of sinking blocks 114 each time, such as 3 blocks, sets the time after each sinking, such as 10 minutes, and then sets the sinking rule, such as sequential sinking, random sinking, sinking from both ends toward the middle, sinking of sinking blocks 114 in multiple areas, and starts the control signal given by the device control computer 22 to make the mechanism inside the fixed end 112 move, and the motor and screw inside the fixed end are used to move to drive the actuator cylinder 113 to move up and down. The sinking block 114 is fixed on the actuator cylinder 113 and moves with the actuator cylinder 113. The sinking block 114 is preferably made of a softer material to improve the feeling of the human body. For patients after surgery or elderly patients, according to the position of the patient lying on the bed and the position of the surgical wound, the actuator of the wound position is found on the control computer 22 according to the identification area 21 of the bed body 2. According to the size of the wound, the number of sinking blocks is confirmed, and the equipment is started to sink the area of the patient's wound position so that the wound position is not squeezed. When there are fewer caregivers beside the patient, the control computer 22 controls the tilting actuator 123 in the anti-fall actuator assembly 12 to extend, and pushes the outer side of the anti-fall plate 121 to move upward, thereby protecting the patient, preventing him from falling off the bed, and protecting the patient's safety.
[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
