Detailed ways

As shown in Figure 1, the present invention provides a multifunctional medical bed for emergency department, including a retractable support frame 1 for supporting the bed, and the top support of the retractable support frame 1 is connected with an adjustable bed board 2. The side of the adjustable bed board 2 is equipped with a reversible auxiliary table 3 for first aid assistance; the telescopic support frame 1 is used to support the adjustable bed board 2, and can automatically adjust the height of the bed board. The reversible auxiliary platform 3 can assist first aid.

There are four telescopic supports 1, two of which are respectively connected to both sides of the adjustable bed board 2, and the telescopic support 1 includes a walking universal wheel 101 connected to the bottom for driving the whole device to move. The walking universal wheels 101 can conveniently drive the entire emergency bed to move, which is convenient for transporting patients, saves the physical strength of emergency personnel, and speeds up the rescue.

As shown in Figures 1 and 3, the wheel shaft of the walking universal wheel 101 is connected with an adjustable lifting frame 102 through a coupling, and a cross-stayed beam 103 is connected between the adjustable lifting frame 102 through a hinge shaft. The top of the adjustable lifting frame 102 is plugged with a load-bearing beam 104, and the load-bearing beam 104 is connected to the bottom of the adjustable bed board 2; Frame structure, thus improving the stability and load-bearing capacity of the emergency bed.

Preferably, the adjustable lifting frame 102 includes a load-bearing base 105 made of hollow stainless steel plate, the upper surface of the load-bearing base 105 has a rotary drive motor 106, and the output shaft of the rotary drive motor 106 is sleeved with a connection Flange 107, the other end top of the connecting flange 107 is sleeved with a rotating sleeve shaft 108 for rotating and lifting; the rotating sleeve shaft 108 includes outer sleeves 109 at the upper and lower ends and a The inner sleeve 110 and the connection between the outer sleeve 109 and the inner sleeve 110 are provided with matching rotating threads, and the outer sleeve 109 at the top is connected to the lower surface of the load-bearing beam 104 .

It is further supplemented that a living hinge 111 is installed at the connection between the outer sleeve 109 and the load-bearing beam 104, and a fixed pin 112 is also connected between the living hinge 111 and the load-bearing beam 104, and the movable hinge 111 is movable. When it is not fixed, the outer sleeve 109 at the bottom can rotate around the axis, and then the entire adjustable lifting frame 102 and the bottom structure can be conveniently put down or folded to the lower surface of the adjustable bed board 2 to realize the storage operation, and put it down for use when needed When inserting the fixed bolt 112 into the positioning hole on the load-bearing crossbeam 104, the relative fixing of the adjustable lifting frame 102 and the adjustable bed board 104 can be realized to ensure the stability of the emergency bed.

After the adjustable lifting frame 102 is put down, the overall height can be adjusted according to the actual situation. For example, when some critically ill patients cannot move significantly, the emergency bed is directly moved to the side of the operating bed, and the rotation drive motor 106 is adjusted to rotate the drive motor. The output shaft of 106 rotates, and the connecting flange 107 synchronously drives the rotating sleeve shaft 108 to rotate. When the rotating drive motor 106 rotates counterclockwise, the output shaft of the rotating driving motor 106 drives the outer sleeve 109 of the rotating sleeve shaft 108 to rotate counterclockwise. When the inner sleeve 110 rotates in the opposite direction relative to the outer sleeve 109, it is screwed out from the outer sleeve 109, thereby increasing the overall height, and directly adjusting the emergency bed to the state parallel to the operating bed, thereby reducing the movement range of the patient, and the maximum Minimize damage to patients.

As shown in Figures 1 and 2, the adjustable bed board 2 includes an outer fixed bed beam 201 installed on the outermost periphery and an inner adjustable bed board 202 installed and fixed in the middle, the inner adjustable bed board 202 and the outer fixed bed beam 201 is connected with an electric push rod 203 for adjusting the relative angle between the two; the outer fixed bed beam 201 is a stainless steel hollow square steel pipe, and the inner surface of the outer fixed bed beam 201 is excavated for interlocking with the electric push rod 203. The electric push rod 203 includes a push-pull drive motor 208 for providing a power source, and a spring push rod 209 with compression performance is connected to the output shaft of the push-pull drive motor 208 .

It is further illustrated that the inner adjustable bed board 202 includes two separate stainless steel bed board frames 210, the joints of the stainless steel bed board frames 210 are connected with a rotating horizontal axis 211, and the sides of the stainless steel bed board frames 210 are inlaid with Motor installation groove 212, described motor installation groove 212 is used for fixedly installing push-pull driving motor 208, and the telescopic spring 213 with good tensile performance is also connected between the lower surfaces of two stainless steel bed frame 210.

Generally, when not in use, the entire adjustable bed board 2 is in a folded storage state, and the telescopic spring 213 connected to the lower surface of the stainless steel bed board frame 210 is also in a relaxed state. When the bed needs to be used, the electric push rod 203 starts to work: first The push-pull driving motor 208 is started, and the output shaft of the motor is pushed outward, driving the spring push rod 209 to move outward, and the spring push rod 209 moves outward along the movable slide rail 207, and then the stainless steel bed frame 210 is pulled apart until it is flattened at both ends; When it needs to be stored, the push-pull drive motor 208 recovers the spring push rod 209 toward the center of the inner side, and the stainless steel bed frame 210 is retracted inwardly around the horizontal axis of rotation 211 to realize the automatic folding operation of the bed.

As shown in Fig. 2, Fig. 3 and Fig. 4, an adjustable platform 204 with a shock-absorbing function is installed at the head and tail of the inner adjustable bed board 202, and the upper surface of the adjustable platform 204 is wrapped with a sponge mattress 205, The secondary collision injury of the patient can be prevented by setting the sponge mattress 205. The upper surface of the outer fixed bed beam 201 is vertically equipped with a reversible guardrail 206 with a protective function, and the reversible guardrail 206 can be fixed around the outer side of the bed. The beam 201 rotates, and turning up the reversible guardrail 206 when needed can effectively prevent the patient from falling during transportation, and also give the patient a certain amount of support and support, and can be turned down when not needed, which is convenient for storage and saves storage space.

Due to the different conditions of different patients, the requirements for the lying posture of each patient are different. In the early stage of rescue, excessive tilting during the transportation process will not only increase the pain of the wounded and sick, but also cause the deterioration of the wounded and sick, and it is easy to give the wounded The patient causes secondary injury, which greatly reduces the efficiency of rescue, especially for the wounded and sick with fractures, internal injuries and internal bleeding, which may even endanger their lives. Therefore, it is very important to maintain the correct body posture when rescuing critically ill patients. For patients with fractures, a relaxed position should be maintained to reduce the pressure on the bones; for patients with cardiopulmonary arrest, they should lie flat on a hardwood bed to avoid twisting of the head, neck and trunk; in addition, the inclination of the emergency bed during intravenous injection may Cause air to leak into in the intravenous injection tube, bring life danger to the wounded and sick, therefore need to carry out inclination automatic adjustment operation according to actual situation to sponge mattress 205 by adjustable platform 204.

Two layers of stainless steel plates are formed, and damping springs 216 are also installed between the upper and lower layers.

As shown in FIGS. 2 and 5 , the reversible auxiliary table 3 includes a reversible table 301 for being accommodated on the right side of the adjustable bed board 2 , and the reversible hinge shaft 302 passes between the reversible table 301 and the adjustable bed board 2 Connected, the upper surface of the turning table 301 is vertically installed with an infusion stand 303 with a lifting adjustment function on the inner side near the bed board, and the outer side of the turning table 301 is dug with a disinfection storage tank 304 for placing medical instruments; 301 forms a reversible connection with the main body of the emergency bed by turning over the hinge shaft 302, so that the turning table 301 can be turned up and down conveniently, so that the storage operation can be realized conveniently, which effectively saves space and is convenient for storage; the infusion stand 303 can be used It is convenient to hang the infusion bottle for infusion, and the disinfection storage tank 304 is used for storing medical instruments and can be easily disinfected, so the emergency bed can be used as a simple operating table.

It is further illustrated that a power supply battery 305 is installed on the lower surface of the turning platform 301, and the output end of the power supply battery 305 is connected to a power supply board 306 through a wire, and the power supply board 306 is embedded in the rear side of the turning platform 301 On the other hand, the power output end of the power supply storage battery 305 is also connected with a single-chip microcomputer control board 307 for automatically adjusting the adjustable bed board 2; Power supply, the power supply board 306 is used to supply power to other electrical appliances, which is convenient for using some emergency rescue medical devices.

When it is necessary to adjust the angle, start the lift drive motors 214 at the head and tail respectively. When the lift drive motors 214 at the head and tail do not move synchronously, an up and down inclination will be generated, and then the inclination angle of the balance support plate 215 at the top will be changed to meet different inclination requirements. When guaranteeing that the device is absolutely balanced, the synchronous action of the first and last lifting drive motors 214 is realized, and the starting and stopping of the lifting drive motors 214 in different positions are all controlled by the single-chip microcomputer control panel 307 mobilizing the internal electronic drive circuit to realize closed-loop feedback automatic regulation, which can Accurate adjustment is realized to ensure complete synchronization; since the lifting drive motor 214 will generate greater vibration when moving up and down, a shock absorbing spring 216 is added to slow down the vibration, so as to ensure the stability of the emergency bed and reduce the damage to the injured.

As shown in Figure 6, described single-chip microcomputer control board 307 comprises single-chip microcomputer controller 308, and the SPI bus port of described single-chip microcomputer controller 308 is connected with the signal processing module 309 that is used for signal acquisition, and the GPIO signal output end of single-chip microcomputer controller 308 is connected There is an action execution module 310 for driving each motor; the single-chip controller 308 is used for signal collection and analysis, and the signal processing module 309 performs real-time collection operation on the current state of the emergency cot.

It needs to be added that the controller adopts the ARM chip of the model LM3S308 with Cortex-M3 as the core. The advantages of Cortex-M3 are low power consumption, low cost, and high performance; Adopt the transmission format of 1 start bit, 8 data bits, and 1 end bit; on the one hand, because the human body is not sensitive to small angles of inclination, on the other hand, in order to reduce the disturbance at the balance point, avoid the electric push rod in the balance The point is frequently repeatedly started, although the angle measurement accuracy of the sensor is 0.1°, the threshold at the balance point is set to ±1° in the program algorithm, and when the angle between the emergency cot and the horizontal plane is greater than ±1°, the controller will send a signal to the driver Send a command to control the action of the electric push rod, otherwise the electric push rod will remain in its original state.

The action execution module 310 includes a synchronous reset switch 314 for controlling circuit on-off and a power regulator 315 for adjusting the working state of the motor. The power regulator 315 is connected to the PWM wave output module of the single-chip control board 307, The synchronous reset switch 314 is connected to the driving end of the push-pull drive motor 208 and the lifting drive motor 214, and a power amplifier 316 is also connected between the power regulator 315 and the synchronous reset switch 314, and the power regulator 315 is controlled by a single-chip microcomputer control board. 307 outputs a PWM wave signal for driving, adjusts the output current of the power regulator 315 by adjusting the duty cycle of the PWM wave signal, and then performs an amplification operation through the power amplifier 316 to control the working state of the motor. The synchronous reset switch 314 The switching states of different motors can be adjusted conveniently to form a closed-loop feedback adjustment mechanism.

For example, when it is necessary to realize the synchronous action of the lifting drive motors 214 at the four corners, first the synchronous reset switch 314 outputs a reset signal to control each lifting drive motor 214 to return to the original position of the lowest limit, and then start the four lifting drive motors 214 simultaneously. In addition, the power regulator 315 controls the same rotating speed to realize synchronous action and synchronous start and stop, so as to realize complete synchronization and ensure the balance performance of the top mechanism.

What needs to be added is that the closed-loop feedback control principle is adopted, and the control system is designed as a closed-loop feedback control system based on the principle of "detecting deviations and correcting deviations". Compared with the open-loop control system, although the structure of the closed-loop control system is relatively complicated, but Its anti-interference ability is strong, and in the case of consistent input calibration accuracy, components and devices with low accuracy can be used to form a higher-precision control system.
