As shown in figures 1 and 2, before the novel medicine dressing changing device is used, medical staff move the novel medicine dressing changing device to an area needing to change or debride through a handle 101, then remove a brake mechanism of a wheel, and then enter debridement or medicine changing operation. The staff adjusts the upper and lower height of the lower support body 2 according to the sitting posture height of the patient, when the handle of the power switch S1 is shifted leftwards, then, the 1, 2 feet and the 3, 4 feet of the power switch S1 are respectively communicated, thus, the positive and negative poles of the first set of electric telescopic rod M1 are electrified, the piston rod of the first set of electric telescopic rod pushes the lower support body 2 to move upwards, the power switch S1 is closed after the required height is reached, and the lower support body 2 moves upwards along the power output shaft of the motor speed reducing mechanism M through the shaft hole. When the handle of the power switch S1 is shifted to the right, the 1, 2 and 5, 6 feet of the power switch S1 are respectively communicated, so that the negative and positive poles of the first set of electric telescopic rod M1 are electrified, the piston rod of the first set of electric telescopic rod drives the lower support body 2 to descend to the required height, and the power switch S1 is turned off. After the height is adjusted, the patient puts the lower leg part or the foot part at the upper end in the lower support body 2, and then the staff adjusts the first power switch S to enable the upper support body 3 to be vertically positioned at the upper end of the lower support body 2. When the handle of the power switch S is shifted leftwards, the pins 1 and 2, the pins 3 and 4 of the power switch S are respectively communicated, so that the power output shaft of the motor speed reducing mechanism is electrified to drive the upper support body 3 to rotate clockwise, and the power switch S is turned off after the required angle is reached. When the handle of the power switch S is shifted to the right, the pins 1 and 2, the pins 5 and 6 of the power switch S are respectively communicated, so that the negative and positive poles of the motor speed reducing mechanism are electrified, the power output shaft drives the upper support body 3 to rotate anticlockwise, and the power switch S is turned off after the required angle is reached.
As shown in the figures 1 and 2, when the leg or foot of the patient is put well and the upper support body 3 is positioned at the upper part of the lower support body 2, if the medical staff needs to fix the leg or foot (exposed to the affected part) of the patient can shift the handle of the power switch S2 to the right, so that the 1, 2, 5 and 6 of the power switch S2 are respectively communicated, and thus, the piston rod of the second set of electric telescopic rod M2 is electrified to drive the upper support body 3 (including the whole motor speed reducing mechanism) to move downwards and the power switch S2 is turned off after the required height is reached. After the subsequent dressing change or debridement is finished, the medical staff shifts the handle of the power switch S2 leftwards, so that the 1, 2 and 3, 4 feet of the power switch S2 are respectively communicated, thus, the positive and negative poles of the second set of electric telescopic rod M2 are electrified, the piston rod of the second set of electric telescopic rod drives the upper support body 3 to ascend, and the power switch S2 is closed after the required height is reached (the lower end of the upper support body 3 is separated from the legs or feet of the patient), so that the legs and feet of the patient can be lifted to be separated from the lower support body 2, and dressing change or debridement is finished. When the upper support body 3 does not clamp the legs or the upper ends of the feet of a patient at the descending height, the acting force of the feet of the patient on the force sensitive resistors RT and RT1 is relatively small, so that the resistance values of the force sensitive resistors RT and RT1 are relatively large, the base voltage of the positive electrode of a 24V power supply entering the NPN triode Q1 after being respectively subjected to voltage reduction and current limitation through the force sensitive resistor RT or RT1 and the RP or RP1 is lower than 0.7V, the NPN triode Q1 is in a cut-off state, the control contact end and the normally closed contact end of the relay K are closed when the relay K is continuously powered off, and the electric telescopic rod M2 continuously drives the upper support body 3 to descend to clamp the legs and the feet of the patient. When the upper support body 3 descends to a height to clamp the upper ends of the legs or the feet of a patient, because the acting force of the legs or the feet of the patient on the force sensitive resistor RT or RT1 is relatively large (whether the upper and the lower detection has a better effect on clamping the legs or the feet of the patient or not is prevented, only one force sensitive resistor RT or RT1 is adopted and is not effectively contacted with the legs or the feet of the patient and cannot be effectively detected and controlled), therefore, the resistance value of the force sensitive resistor RT or RT1 is relatively small, the positive electrode of a 24V power supply enters the base voltage of an NPN triode Q1 after being subjected to voltage reduction and current limitation through the force sensitive resistor RT or RT1 through RP or RP1, the base voltage is higher than 0.7V, the NPN triode Q1 is in a conducting state, the collector outputs a low level and enters the negative power supply input end of a relay K, the relay K is electrified to attract the control contact end and a normally closed contact end of the relay K, and the normally closed contact end of the relay K are connected in series between one path of the power supply output end 5 feet of the third power supply of the telescopic rod of the power supply of the telescopic rod S2 and the second set of the negative power supply input end M2 through a lead wire, therefore, the electric telescopic rod M2 can lose power and no longer work at the moment, the discomfort of the patient caused by overlarge acting force applied to the legs and the feet of the patient due to the overlarge descending height of the upper supporting body 3 driven by the electric telescopic rod is prevented, and the purpose of intelligent control is achieved.
As shown in fig. 1 and 2, in the prompting circuit, when the power of the storage battery G is large (higher than 24V) during operation, the positive electrode of the power supply with the voltage of more than 24V is reduced through the resistor R1, the current is limited, the voltage enters the base of the NPN transistor Q2, the base is higher than 0.7V, the NPN transistor Q2 turns on the collector to output a low level, the low level enters the base of the NPN transistor Q3, the base of the NPN transistor Q3 has no proper forward bias and is in a cut-off state, the NPN transistor Q3 is not turned on, the light emitting diode VL is not powered and emits light, and the power of the storage battery G is sufficient. When the electric energy of the storage battery G is less (lower than 24V), the positive pole of the power supply is subjected to voltage reduction and current limiting through the resistor R1 and enters the base electrode of the NPN triode Q2 and is lower than 0.7V, the collector electrode of the cut-off NPN triode Q2 does not output low level and enters the base electrode of the NPN triode Q3, the base electrode of the NPN triode Q3 is subjected to voltage reduction and current limiting through the resistor R2 to obtain proper forward bias voltage and is in a conducting state, the collector electrode outputs low level after the NPN triode Q3 is conducted and enters the power supply input end of the cathode of the light emitting diode VL, the light emitting diode VL is electrified and emits light, a user is prompted that the electric energy of the storage battery G needs to be charged less, and subsequent normal use (the storage battery can still be used for a period of time after the front undervoltage is generated) is ensured. The resistor R1 can be replaced by an adjustable resistor, technicians need to determine the resistance value of the adjustable resistor before batch production, a storage battery is replaced by an adjustable output direct current power supply, the output of the direct current power supply is adjusted to 23.9V, then the resistance value of the adjustable resistor is slowly adjusted until the resistance value of the adjustable resistor is adjusted to be in place after the light emitting diode emits light, then the power supply is disconnected to measure the resistance value of the adjustable resistor, the measured resistance value is the resistance value of the adjustable resistor in subsequent batch production, and the resistance value of the adjustable resistor is directly adjusted to be in place before subsequent batch production. Before mass production, the resistance values of the adjustable resistors RP and RP1 need to be determined, specifically, before the determination, an object simulating the feet and legs of a human is placed between the lower support body 2 and the upper support body 3, then the power switch S2 is turned on, then the resistance values of the adjustable resistors RP and RP1 are repeatedly adjusted, the power switch is turned off just after the lower support body 3 is adjusted to press the simulation object, then the power supply is turned off to measure the resistance values of the adjustable resistors RP and RP1, the measured resistance values are the resistance values of the adjustable resistors RP and RP1 produced in subsequent mass production, and the resistance values of the adjustable resistors are directly adjusted in place before the subsequent mass production. In the circuit, the resistances of the resistors R1, R2 and R3 are respectively 7.8M, 47K and 4.2K; the models of the adjustable resistors RP and RP1 are 8M (the models are respectively adjusted to be 2.3M in the embodiment); the light emitting diode VL is a red light emitting diode; relay K is a DC24V relay; the model numbers of NPN triodes Q2, Q3 and Q1 are 9013; the force-sensitive resistors RT and RT1 are IMS-C04N. The invention has simple and compact structure and convenient use, brings convenience to patients and medical care personnel, prevents the leg or foot of the patient from influencing subsequent dressing change or debridement, can also prevent the patient from being painful due to over-tight clamping, and can prompt charging in time when the storage battery is out of power, thereby achieving the purpose of intelligent control.
