Description

Technical Field

[0001] This utility model relates to a special equipment for handling remains, used by funeral home staff to organize, clean, and apply makeup to the remains. Background Technology

[0002] Currently, the funeral industry generally uses standard stainless steel autopsy tables based on the "GA / T 750-2021 Stainless Steel Autopsy Table" for body disposal. However, autopsy and mortuary procedures differ significantly in their actual content and operational habits. The use cases and user needs of body disposal beds are quite specific, and stainless steel autopsy tables and other general equipment cannot meet the requirements of funeral home staff for handling, cleaning, and preparing bodies. Currently, there are no customized disposal bed products or standards for the needs of funeral service personnel. Therefore, it is necessary to develop specialized equipment for body disposal and establish an industry or national standard for body disposal beds. Utility Model Content

[0003] The purpose of this invention is to provide an intelligent body disposal bed.

[0004] The purpose of this utility model is achieved as follows: an intelligent body disposal bed, characterized in that it consists of a frame assembly, a rinsing system, a bed board and lifting and tilting mechanism, an air purification system, and an intelligent operating system;

[0005] The frame assembly is used to contain and support the bed board and the lifting and tilting mechanism, as well as to support the stainless steel water tank structure inside the bed. It consists of an outer frame, a folding table, a cleaning nozzle holder, an outer shell panel, and a disinfection cabinet. The outer shell panel contains the outer frame and water tank structure inside, forming a flat and beautiful appearance on the outside.

[0006] The rinsing system includes an external cleaning nozzle, a cleaning nozzle holder mounted on the outer frame at the head of the bed board, a water tank located inside the outer frame, and a drain pipe at the bottom of the water tank.

[0007] The bed board and lifting and tilting mechanism include the bed board and the lifting and tilting mechanism; the bed board is divided into three modules, from the head to the tail of the bed, namely the head module, the body module, and the leg module; the head module and the leg module are single boards that can only be raised and lowered; the body module bed board is divided into two parts, left and right, with a total of four bed boards. These four boards are raised and lowered simultaneously with the head and leg bed boards. After rising to the same level as the top of the outer frame, the left and right bed boards of the body module can tilt 45 degrees on one side to assist the operator in turning the body over;

[0008] The air purification system consists of an air inlet, an internal air duct, a static pressure box, an external air duct, and a purification fan. The air inlets are located on both sides of the bed board and at the upper end of the inner side of the water tank. When the purification fan is working, it draws air from the vicinity of the bed board to prevent the gas emitted by the remains from escaping. The internal air duct is arranged in the gap between the water tank inside the bed and the side push rod and the lifting column, connecting the air inlet and the static pressure box.

[0009] The objective of this utility model can also be achieved in the following way:

[0010] The outer shell of the frame assembly has installation positions for electrical cabinets, fan cabinets, and maintenance doors on the side of the bed. The outer frame at the head of the bed is equipped with a folding table and a cleaning nozzle holder, which makes it convenient for staff to access tools for makeup and cleaning operations while working at the head of the bed.

[0011] The outer frame is welded from stainless steel profiles, and stainless steel plates are welded inside the frame. The stainless steel plates are welded together and sealed to form an integral water tank. The outer shell trim is also made of stainless steel. The outer shell trim at the head of the bed extends inward to divide the electrical system cabinet at the head of the bed, and the air disinfection and purification system installation cabinet is divided at the tail. The disinfection equipment cabinet is divided on the left side of the bed.

[0012] Based on the installation position of the lifting column base on the outer frame, the reinforcing beams at the bottom of the outer frame are arranged, and the main load-bearing lifting column has a bracket base.

[0013] The stainless steel plates inside the outer frame are welded together to form a whole water tank; the side walls of the water tank have detachable panels, which are installed on the side walls using stainless steel buckles. The detachable panels can be removed when cleaning and maintaining the inside of the water tank for easy operation.

[0014] The removable wall panels protrude inward and are fitted with rubber sealing strips at the joints to ensure the water tank is waterproof; exhaust vents are located at the top of the side wall panels on both sides of the water tank for connecting to an external fan of the air purification system.

[0015] The head and leg modules of the lifting and tilting mechanism are connected to a single lifting column via a bracket; the middle of the body module bed board is connected to the body module bed board bracket via a hinge, and the outer side is connected to a side push rod via a bracket; the body module bed board bracket is connected to two lifting columns; when the four lifting columns and two side push rods are raised and lowered synchronously, the overall lifting function of the bed board is realized; when the two lifting columns of the body module stop, the single side push rod is raised to achieve the tilting of the bed board.

[0016] The working stroke of the lifting column of the synchronous lifting head module and leg module is 180mm, the lifting stroke of the body module is 100mm, and the tilting angle is 0-45°.

[0017] The bed board is made of acrylic material, and the surface of the bed board has holes for easy drainage.

[0018] The internal air duct of the air purification system is arranged inside the water tank of the bed and in the gap between the side push rod and the lifting column, connecting the air inlet and the static pressure box. The static pressure box, as a large space box connecting the air inlet and the fan, plays the role of reducing the dynamic pressure of the air purification system, increasing the static pressure, stabilizing the airflow, and reducing airflow noise and vibration.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this utility model integrates various functions required for body disposal, realizing the completion of body cleaning, embellishment, and air purification in one device, and by combining the application of an electronic control system and a modern voice control system, it realizes intelligent body disposal.

[0048] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0049] The purpose of this invention is to design a specialized device to meet the practical needs of body disposal. This device enables intelligent lifting, turning, and handling of bodies, facilitating cleaning, grooming (cosmetics, dressing), and other procedures. It is equipped with a purification system, drainage system, electrical control system, and voice control function to achieve intelligent operation, thereby reducing the human resource consumption and environmental pollution that could harm operators during body disposal. Furthermore, this invention aims to establish industry and national standards for this specialized equipment.

[0050] Based on the actual needs of mortuary work, the proposed design of the body disposal bed aims to achieve functions such as body positioning, water rinsing, waste disposal, and air purification; to assist operators in transferring and turning the body, and to reduce manpower consumption during the body disposal process. The structural design requirements and functions of the body disposal bed are described in detail below.

[0051] (1) Assistance in adjusting body position. Body transfer location: Compared with a normal human body, a body has no mobility or support capabilities and needs to be transferred manually. The design of the mechanism should facilitate the transfer of the body by personnel. This requires that the work platform be flush with the four sides.

[0052] Body washing location: To prevent water from splashing outwards, the work platform must be recessed relative to the surrounding edges, forming a water tank structure with the edges and wall panels. Additionally, to facilitate washing of key areas such as the head, the work platform can be partially recessed while still being generally recessed.

[0053] Side-turning changing position: When the operator needs to change the clothes of the body, the work platform is required to have a side-turning function, which can turn the body to the side at a 45-degree angle to assist the operator in turning the body over for changing clothes.

[0054] At the same time, the body should not be moved at high speeds or with large movements to avoid causing secondary damage. The assistive positioning function should, as far as possible, meet the needs of funeral service personnel for easy cleaning of specific areas and dressing of the deceased.

[0055] In summary, the operating platform needs to complete three main actions: overall platform lifting, individual head / body / leg lifting and lowering, and left / right flipping.

[0056] (2) Disinfection and air purification requirements. Air purification function: The air purification function should be activated when personnel handle the remains. The air purification system should not only be able to remove polluted air from the work area, but also remove dust, sterilize and disinfect the polluted air. Reduce ambient air pollution.

[0057] Corrosion resistance of the treatment bed material: The bed surface must be thoroughly cleaned and disinfected before and after each workday, and after the disposal of each body. Commonly used disinfectants in the industry are corrosive to metals, necessitating that the treatment bed material possess corrosion resistance.

[0058] (4) Waterproofing requirements. The disinfection and cleaning of remains requires spraying disinfectant and rinsing with running water; electrical control equipment, such as electric cylinders, may malfunction or short circuit if they come into direct contact with liquids. These operating environments place high demands on the waterproofing of the treatment bed. The treatment bed should be designed to be waterproof, with both water guiding and drainage devices to prevent waste liquid residue and ensure that the non-ventilated areas under the bed can dry quickly.

[0059] (5) Control Requirements. The body disposal bed needs to be equipped with a button control panel. Button panel control is a traditional physical operation method, allowing users to operate the equipment intuitively through clearly defined buttons or a touch screen. The operation should be simple, intuitive, and easy to learn. It should still be able to control accurately and reliably even in noisy environments or where voice recognition is limited.

[0060] Furthermore, the mortuary bed also needs to be equipped with voice control, based on neural network natural language recognition technology, allowing operation and adjustment of the bed through voice commands. This frees up the operator's hands, making it more convenient in special scenarios such as when hands are limited or in sterile environments. In quiet environments where the operator's hands are restricted, voice control can be used to complete operations quickly and efficiently. When the environment is noisy or voice recognition is limited, the button panel still ensures stable system operation and precise control.

[0061] (6) Mobility Requirements. The body disposal bed should be able to be transported over short distances, and casters should be provided underneath the bed. The casters should also have a locking function to ensure that the bed does not move during operation. The overall design of the disposal bed should be as lightweight as possible to facilitate movement.

[0062] (7) Work area and storage requirements. Specific equipment is required when performing makeup, dissection, and embalming on the body. Small tables should be provided for easy access to the equipment. To facilitate the makeup operation, the width of the head frame should not be too wide to avoid the operator having to bend over or turn to the side at the head of the bed to complete the makeup operation.

[0063] Therefore, this utility model is structurally designed with five parts: frame assembly, washing system, bed board and lifting / tilting mechanism, air purification system, and intelligent operating system.

[0064] I. Frame Assembly: Composed of outer frame, folding table, cleaning nozzle holder, outer shell trim panel and disinfection equipment cabinet.

[0065] The frame assembly houses and supports the bed board and lifting / tilting mechanism, as well as the internal stainless steel sink structure. The outer shell panel encloses the frame and sink structure, creating a smooth and aesthetically pleasing exterior. The outer shell panel is made of stainless steel with a painted finish, with the top section constructed of 304 stainless steel for corrosion resistance and easy cleaning and disinfection. It provides mounting locations for the electrical cabinet, fan cabinet, and maintenance doors on the side of the bed. Furthermore, a folding table and cleaning nozzle holder are installed on the outer frame at the head of the bed, allowing staff to easily access tools for makeup and cleaning while working at the bedside.

[0066] The outer frame is welded from stainless steel profiles, with stainless steel plates welded inside. These stainless steel plates are welded together to form a sealed, integrated water tank. The outer shell trim is also made of stainless steel. The headboard trim extends inward to create an electrical system cabinet at the head of the bed, while an air disinfection and purification system cabinet is created at the tail. A disinfection equipment cabinet is located on the left side of the bed.

[0067] The outer frame is welded from 304 stainless steel square tubing, and the interior of the frame is formed by welding 304 stainless steel sheet metal, creating an integrated water tank structure and dividing the space for electrical cabinets and purification cabinets.

[0068] Based on the installation position of the lifting column base on the outer frame, the reinforcing beams at the bottom of the outer frame are arranged. There are a total of 8 support bases for the four main load-bearing lifting columns. Therefore, eight horizontal reinforcing beams are arranged at the bottom of the outer frame to bear the weight of the lifting columns and the remains. At the same time, a longitudinal beam of the same length as the outer frame is added to connect the 8 horizontal beams.

[0069] To verify whether the reinforcing beams at the bottom of the outer frame can meet the requirements for the weight of the lifting column and the remains, the bed frame was simulated using the finite element method.

[0070] The simulation model was imported using the Simulation plugin in Solidworks software. Fixed constraints were applied to the welded joints between the bottom outer frame of the bed body and the six vertical columns to simulate the actual support function of the casters.

[0071] II. Flushing System: This includes an external cleaning nozzle (not shown in the figure), a cleaning nozzle holder mounted on the outer frame at the head of the bed board, a water tank located inside the outer frame, and a drain pipe at the bottom of the water tank.

[0072] The outer frame is internally welded with stainless steel plates, which are then welded together to form a seamless, integrated water tank. Removable side panels are located on both sides of the tank, secured with stainless steel buckles. These panels can be easily removed for cleaning and maintenance. The removable panels protrude inwards and are sealed with rubber strips at the joints to ensure the tank's interior remains waterproof. Vents are located at the top of both side panels for connecting to an external fan in an air purification system.

[0073] Water tank structure such as Figure 7 As shown, the stainless steel panel on the headboard side is recessed inward to form the space for the electrical system cabinet, and the sheet metal on the footboard side is recessed inward to form the air purification system installation cabinet. A removable maintenance door is provided on the inner wall panel of the bed frame. Stainless steel buckles are used to attach the side panel to the bed frame side wall, allowing the panel to be removed for easy access when cleaning and maintaining the interior of the bed. The removable panel protrudes inward and is fitted with a rubber sealing strip at the joint to ensure the waterproofness of the bed interior.

[0074] Two drain holes are made at the bottom of the sink to connect to the drain pipe, such as... Figure 8 As shown. The support base raises the bottom of the lifting column and side push rod away from the bottom of the water tank, so that water accumulation at the bottom of the bed will not soak the lifting column and side push rod.

[0075] III. Bed Board and Lifting / Tilting Mechanism: This includes the bed board and the lifting / tilting mechanism.

[0076] The bed is divided into three modules, from head to tail: the head module, the body module, and the leg module. The head and leg modules are single, integrated panels that can only be raised and lowered, not tilted. The body module consists of four panels in two sections, left and right. These four panels can be raised and lowered simultaneously with the head and leg modules. After rising to the level of the top of the outer frame, the left and right panels of the body module can tilt 45 degrees on each side to assist the operator in turning the body over.

[0077] The bed board is made of acrylic material, featuring high load-bearing capacity, corrosion resistance, and a smooth, easy-to-clean surface. Perforations on the bed board surface facilitate drainage. The head and leg modules are directly connected to the bottom bolts via brackets, while the body module bed board is connected to the central support via hinges, and the outer sides are connected to the side push rods via brackets.

[0078] The lifting and tilting mechanism consists of three parts: a head module, a body module, and a leg module. The bed boards of the head and leg modules are connected to a single lifting column via a bracket. The body module bed board is connected to a body module bed board bracket via a hinge in the middle, and the body module bed board bracket is connected to two lifting columns.

[0079] When the four lifting columns and two side push rods rise and fall simultaneously, the entire bed board can be raised and lowered. When the two lifting columns of the body module stop, raising one side push rod will allow the bed board to tilt to the side.

[0080] The synchronously lifting head and leg modules have a lifting column working stroke of 180mm. The body module has two bed boards on each side, with hinges connecting the outer sides of the bed boards to side push rods. The body module's lifting stroke is 100mm, and its tilting angle is 0-45°.

[0081] Bed board position definition: The lifting and tilting mechanism defines the bed board positions as follows according to design requirements: overall high position, overall low position, head recess, leg recess, left tilting position, and right tilting position, for a total of 6 bed board positions.

[0082] The overall height of the bed board is defined as follows: The overall height of the bed board is used for the transfer of remains. The overall height of the bed board is defined as the bed board of the head module, body module, and leg module being flush with the top of the outer frame. The height of this bed board position is the same as the height of the trolley used for transferring remains. This allows workers to simply move the remains laterally from the trolley to the bed board without being obstructed by the outer frame when transferring remains from the trolley.

[0083] The definition of a lower overall bed board position is: based on the height of the outer frame (i.e., the overall height of the bed board), it is lowered by 100mm. The lower overall bed board position is used when cleaning the remains. In this position, the remains are lower than the outer frame and can be surrounded by the outer frame. During the cleaning process, the sewage flows downward into the water tank and will not overflow.

[0084] The head and leg recesses are defined as follows: the head and leg modules of the bed board are recessed 80mm further down from the overall low position of the bed board. This position is used by the operator to focus on cleaning the head and legs, and to facilitate dressing the user.

[0085] The left / right turning position is defined as follows: when the bed board is in a high position, the body module of the bed board tilts 45° to the side to assist the operator in turning the body. The side push rod is used to further raise the body module, causing one side of the bed board to tilt 45° to the side. When the bed board is raised to the side, the body can be lifted and tilted to one side. At this point, the operator only needs to use the tilting tendency of the body to easily turn the body over. This simplifies the turning operation that previously required two people, facilitating subsequent body preparation and dressing.

[0086] The bed board tilting mechanism consists of the following components: Figure 12 As shown. Includes mounting base plate 33-01, lower hinge 33-02, side push rod 33-03 (DC motor cylinder), linear bearing bracket 33-04, optical axis 33-05, linear bearing 33-06, optical axis support 33-07, upper hinge connecting plate 33-08, upper hinge 33-09, bed board connecting plate 33-10, and bed board 33-11.

[0087] The bottom end of the side push rod is mounted on the base plate via a hinge, and the upper end of the side push rod is connected to one side of the bed board of the body module via a hinge. The bed board of the body module is connected to the body module bed board mounting bracket via a hinge.

[0088] When the rising column and the side push rod move upwards in sync, the body module completes its overall ascent. When the rising column is stationary while the side push rod moves upwards, the body module performs a side-tipping function.

[0089] To prevent asynchrony in position or speed between the side push rod and the lifting main unit during synchronous ascent, a double linear bearing slide rail is used on the upper part of the side push rod as a synchronization error elimination mechanism. This mechanism can structurally offset the displacement error generated when the central lifting column and the side push rod rise and fall simultaneously, compensating for the shortcomings of short synchronization distance and poor stability of single guide rail. All parts of the buffer mechanism in this solution are standard parts, simplifying the structure, improving interchangeability, and significantly reducing processing and material costs.

[0090] Waterproof design of the bed board lifting and tilting mechanism: Since the treatment bed requires cleaning via running water during use, a pleated cover and waterproof outer shell are designed to enclose the lifting column and side push rod, as shown in Figure 13. The pleated cover is made of PVC, which is waterproof and resistant to acid corrosion. The waterproof outer shell is made of AISI 304 stainless steel. Stainless steel cable trays and conduits are used at the bottom of the lifting column and side push rod to connect to the electrical cabinet at the head of the bed, ensuring watertightness between the electrical equipment and the water-passing space.

[0091] Kinematic analysis of the bed board tipping mechanism:

[0092] Kinematic analysis was performed on the bed board lifting and tilting mechanism. When the slider of the synchronization error elimination mechanism is at its highest point, the right half of the body module lifting and tilting mechanism of the mortuary disposal bed moves. The left half tilting mechanism and the right half folding mechanism are symmetrically designed.

[0093] Selection of lifting columns and side push rods: The central lifting column is a custom-made square lifting column. Based on the position and load requirements of the treatment bed board, the head and leg modules need to be lowered by 180mm compared to the upper surface of the bed frame, and the body module by 100mm. The overall lifting load needs to reach over 200kg. Accordingly, the working stroke of the lifting columns for the head and leg modules is determined to be 330mm-530mm (distance between the lifting column ends), and the working stroke for the body module is 430mm-530mm (distance between the lifting column ends). The maximum load of a single lifting column is 100kg, the operating speed is 10mm / s, the motor is DC24V, and the motor power is 80W. The lifting column has a three-section sleeve structure and a custom-made lifting column flange.

[0094] The side push rod uses a DC motor. For example, based on the bed board position design, a 45° tilting angle is required. Based on kinematic analysis of the tilting mechanism, the push rod stroke is ultimately determined to be 285mm. The push rod housing has magnetic switch mounting slots on the side. Adjusting the positions of three magnetic switches determines the three working positions of the side push rod: lowest, highest, and tilting. The push rod motor operates at DC 24V with a power of 20W. The push rod top uses a flat, direct-end type with an M6 internal thread at the top.

[0095] IV. Air Purification System: To improve the air quality in the working area during body disposal and prevent the escape of toxic and harmful gases, an air purification system is designed for the body disposal bed. The air purification system consists of: air inlets, internal air ducts, a plenum chamber, external air ducts, and a purification fan.

[0096] The air inlets are located on both sides of the bed board and at the upper end of the inner side of the water tank. When the purification fan is working, it draws air from the vicinity of the bed board to prevent the gas emitted by the remains from escaping.

[0097] The internal air duct is arranged inside the water tank of the bed and in the gap between the side push rod and the lifting column, connecting the air inlet and the static pressure box.

[0098] The plenum chamber, as a large space connecting the air inlet and the fan, serves to reduce the dynamic pressure of the air purification system, increase the static pressure, stabilize airflow, and reduce airflow noise and vibration. It can reduce noise, achieve uniform static pressure exhaust, and minimize dynamic pressure loss.

[0099] The purification fan provides negative pressure to the air purification system duct to collect air around the treatment bed. The contaminated air is then treated by an electrostatic dust removal and sterilization device inside the fan before being released into the environment, thus improving the air quality around the treatment bed. The purification fan is customized by the air purification equipment manufacturer according to the requirements of the treatment bed's air purification system.

[0100] V. Intelligent Operating System: See Figure 16-24 , Figure 16 This is a schematic diagram of the electrical cabinet structure. Figure 17 This is a block diagram of the control system.

[0103] The experimental results of this utility model were verified.

[0104] 1. Testing of the Lifting and Tilting Mechanism of the Treatment Bed: To verify whether the structural design of the treatment bed can achieve its design objectives, the position, speed, and synchronization capacity of the bed board under load of the lifting and tilting mechanism of the treatment bed were tested.

[0105] Bed board lifting and tilting position and movement speed test: Verify the bed board lifting and tilting position and movement speed. Test whether the bed lifting and tilting mechanism can reach the "overall high position," "overall low position," "left tilting position," and "right tilting position" defined in the bed board position definition. Record the actuation time and movement speed of the bed board during each action from the completion of the control command to the bed board's final position, and whether the bed board's movement time and speed meet the requirements. The test prototype's lifting column and side push rod movement speed is 10mm / s, and the test is conducted with the bed board unloaded.

[0106] Test results show that the bed board of the prototype can reach the designed position. The motion time of each movement of the bed board is recorded in Table 1. The motion time of each movement of the bed board is less than 20 seconds, and the actual motion time of the bed board meets the requirements for the motion time of the bed board.

[0107] Table 1 Results of Bed Board Motion Time Test

[0108]

[0109] Test on the Synchronization Capability of Lifting and Tilting under Uneven Load Conditions: To simulate the uneven weight distribution of the human body in real-world use, the lifting and folding mechanism of the bed board was tested for its synchronization capability under uneven load conditions. A simulated load of 30kg was applied to the headrest module, 120kg to the body module, and 50kg to the legrest module, for a total simulated load of 200kg. The synchronization capability of the bed board under the maximum designed load was tested. During the test, the maximum motion error between each bed board module was measured using calipers and recorded. The results are shown in Table 2.

[0110] Table 2 Maximum motion error of the bed board under uneven load conditions

[0111]

[0112] The analysis is based on the error results in Table 2. Under extreme uneven load conditions, the bed board's synchronization capability meets the design requirement of a synchronization error of less than 5mm. During overall lifting, the head and leg modules rise slower than the body module because they have one less lifting column drive. Furthermore, the head module is lighter than the leg module, resulting in a smaller synchronization error between the head and body modules compared to the leg and body modules. During overall descent, the body module bears a larger load, leading to the fastest descent speed, followed by the leg module, with the head module being the slowest.

[0113] The testing contents of the prototype treatment bed are as follows:

[0114] 1. The panel control function of the treatment bed was tested on the prototype, and the button control and bed position display functions of the treatment bed panel were verified.

[0115] 2. By manually moving the bed board to an abnormal working position, the judgment of the preconditions for the bed board lifting command by the treatment bed control system was verified.

[0116] 3. Design a test experiment on the direction and range of voice control of the treatment bed to verify that the voice control system of the treatment bed can guarantee the success rate of voice recognition within a range of 2m.

[0117] 4.
