Description

Technical Field

[0001] The present application relates to the field of medical device technology, and in particular to a control system, method, device, equipment and storage medium for preventing urinary tract damage caused by forced removal of a urinary catheter. Background Art

[0002] Catheterization is one of the common medical operations in clinical practice. A urinary catheter is a tube inserted into the bladder through the urethra to drain urine. It is often used to help patients collect urine or help patients with limited mobility such as those after surgery to urinate. It is also suitable for urine retention caused by lower urinary tract obstruction. Catheterization is also used in rescuing critically ill patients, preoperative preparation for general anesthesia, intravesical drug instillation or bladder flushing, etc.

[0003] A urinary catheter generally includes a tube body and a fixed balloon arranged on the tube body. A urine inlet is arranged at one end of the tube body close to the fixed balloon, and a urine outlet and a water / air injection port are arranged at the other end away from the fixed balloon. When inserting the urinary catheter, the end of the urinary catheter with the fixed balloon is inserted into the urinary tract. After reaching the designated position, the fixed balloon is inflated or injected with water. The inflated or water-injected fixed balloon is used to fix the urinary catheter in the bladder to prevent it from shaking and falling off. Urine enters the tube body through the urine inlet on the tube body and is then led out of the body. When the urinary catheter needs to be removed, the gas or water in the fixed balloon needs to be discharged first to relieve the pressure of the fixed balloon, and then it can be taken out, so as not to damage the urethra.

[0004] At present, almost all patients admitted to the ICU usually have a urinary catheter inserted, but some unconscious patients sometimes forcibly pull out the catheter by themselves after the catheter is inserted. During the process of forcibly pulling out the catheter, the inflated fixed balloon will tear the bladder and urethra, which will seriously damage the urinary tract.

[0005] Therefore, how to prevent the urinary tract from being damaged when the urinary catheter is forcibly pulled out is a problem that needs to be solved urgently. Summary of the invention

[0062] like Figure 1 As shown, an embodiment of the present application provides a control system for preventing urinary tract damage caused by forced removal of a urinary catheter.

[0063] The urinary catheter 100 includes a tube body 101 and a fixed balloon 102 arranged on the tube body 101. The end of the tube body 101 close to the fixed balloon 102 is provided with a urine inlet 103, and the end of the tube body 101 away from the fixed balloon 102 is provided with a urine outlet 104; the end of the tube body 101 away from the fixed balloon 102 is also provided with a water / air extraction port 105, and the water / air extraction port 105 is connected to the internal cavity of the fixed balloon 102.

[0064] The control system includes a power supply module 1, a first conductive member 2, a conductive wearable device 3, a sampling resistor 4, a control module 5, a current / voltage detection circuit 6 and a micro water / air pump 7. The conductive wearable device 3, the power supply module 1 and the first end of the sampling resistor 4 are connected in sequence, the second end of the sampling resistor 4 is connected to the end of the first conductive member 2 close to the fixed balloon 102, the first detection end of the current / voltage detection circuit 6 is connected to the first end of the sampling resistor 4, the second detection end of the current / voltage detection circuit 6 is connected to the second end of the sampling resistor 4, the signal output end of the current / voltage detection circuit 6 is connected to the signal input end of the control module 5, the first signal output end of the control module 5 is connected to the control signal input end of the micro water / air pump 7, the medium inlet of the micro water / air pump 7 is connected to the water / air pumping port 105 of the urinary catheter 100 through a pipeline, and the control module 5, the current / voltage detection circuit 6 and the power input end of the micro water / air pump 7 are respectively connected to the power supply module 1.

[0065] Specifically, the first conductive member 2 is disposed on the tube body 101 and is located on a side of the fixed balloon 102 away from the urine inlet 103 , and the first conductive member 2 extends along the length direction of the tube body 101 ;

[0066] The conductive wearable device 3 is used to be worn on the patient's hand;

[0067] The current / voltage detection circuit 6 is used to detect the current flowing through the sampling resistor 4 / the voltage across the sampling resistor 4;

[0068] The control module 5 is used to control the micro water / air pump 7 to start when the current / voltage detected by the current / voltage detection circuit 6 meets the preset conditions, so that the water or gas in the internal cavity of the fixed balloon 102 can be discharged under the action of the micro water / air pump 7.

[0069] In this embodiment, the working principle of the control system for preventing urinary tract damage caused by forced removal of the urinary catheter is as follows:

[0070] When the patient removes the tube, the conductive wearable device 3 on the patient's hand contacts the first conductive member 2 on the tube body 101, so that the conductive wearable device 3, the power module 1, the sampling resistor 4 and the first conductive member 2 are connected in series in sequence to form a power-on circuit. At this time, current flows through the sampling resistor 4, and the current / voltage detection circuit 6 detects the current flowing through the sampling resistor 4 / the voltage across the sampling resistor 4. The control module 5 determines whether the current / voltage detected by the current / voltage detection circuit 6 meets the preset conditions. When the current / voltage detected by the current / voltage detection circuit 6 meets the preset conditions, the control module 5 controls the micro water / air pump 7 to start, so that the water or gas in the internal cavity of the fixed balloon 102 is discharged under the action of the micro water / air pump 7, so as to achieve timely pressure relief of the fixed balloon 102 when the tube is removed, so that the urinary tract will not be damaged when the catheter 100 is forcibly pulled out.

[0071] The control system for preventing urinary tract injury caused by forced removal of a urinary catheter in this embodiment is capable of detecting the patient's catheter removal action by providing a power module 1, a first conductive member 2, a conductive wearable device 3, a sampling resistor 4, a control module 5, a current / voltage detection circuit 6 and a micro water / air pump 7. When the patient's catheter removal action is detected, the micro water / air pump 7 is controlled to start and discharge the water or gas in the internal cavity of the fixed balloon 102, thereby achieving pressure relief for the fixed balloon 102, and effectively preventing the bladder and urethra from being torn by the inflated fixed balloon 102 when the patient forcibly removes the catheter by himself, causing damage to the patient's urinary tract.

[0072] Specifically, in this embodiment, the first conductive member 2 can be a conductive film, a conductive strip or a conductive sleeve made of a conductive material such as conductive silicone rubber. The first conductive member 2 can be fixed to the surface of the tube body 101 of the existing catheter 100 by bonding, so that the existing catheter 100 can be applied to the present application by adding the first conductive member 2.

[0073] Specifically, the conductive wearable device 3 can be a wearable device made of conductive materials such as conductive silicone rubber that can be worn on the patient's hand. In this embodiment, the conductive wearable device 3 is a conductive rubber glove, and the number of conductive rubber gloves is two, which can be worn on the patient's left and right hands respectively.

[0074] Specifically, the current / voltage detection circuit 6 can be a current detection circuit, which detects the voltage drop across the sampling resistor 4 and performs voltage / current conversion to obtain the current flowing through the sampling resistor 4. When the conductive wearable device 3, the power module 1, the sampling resistor 4 and the first conductive member 2 are sequentially connected in series to form a power-on circuit, the current flowing through the sampling resistor 4 is related to the length of the first conductive member 2 connected in series in the power-on circuit (that is, it is related to the contact position of the conductive wearable device 3 on the first conductive member 2). The shorter the length of the first conductive member 2 connected in series in the power-on circuit, the smaller the resistance in the entire power-on circuit, and the greater the current flowing through the sampling resistor 4;

[0075] The current / voltage detection circuit 6 can also be a voltage detection circuit, which can directly detect the voltage across the sampling resistor 4. When the conductive wearable device 3, the power module 1, the sampling resistor 4 and the first conductive member 2 are connected in series in sequence to form a power-on circuit, the voltage across the sampling resistor 4 is related to the length of the first conductive member 2 connected in series in the power-on circuit (that is, it is related to the contact position of the conductive wearable device 3 on the first conductive member 2). The shorter the length of the first conductive member 2 connected in series in the power-on circuit, the smaller the resistance in the entire power-on circuit, and the greater the voltage across the sampling resistor 4.

[0076] In this embodiment, the current / voltage detection circuit 6 adopts a voltage detection circuit to directly detect the voltage value across the sampling resistor 4. The circuit structure of the current / voltage detection circuit 6 belongs to the prior art and will not be described in detail here.

[0077] Specifically, the water extraction / air extraction port 105 provided at one end of the tube body 101 away from the fixed balloon 102 can be independently provided relative to the water injection / air injection port on the tube body 101 of the urinary catheter 100, or the water injection / air injection port on the tube body 101 of the urinary catheter 100 can be used as the water extraction / air extraction port 105. In this embodiment, the water injection / air injection port on the tube body 101 of the urinary catheter 100 is used as the water extraction / air extraction port 105, and the micro water extraction / air extraction pump 7 is a dual-purpose micro air pump for blowing and suction, so that the present application can be applied without changing the water injection / air injection port of the existing urinary catheter 100.

[0078] Specifically, the power module 1 uses a lithium battery with high energy density, which reduces the volume of the power module 1.

[0079] On the basis of the above embodiments, in one embodiment, the control module 5 includes a threshold memory, a comparator and a main control MCU, the first input end of the comparator is connected to the threshold memory, the second input end of the comparator is connected to the signal output end of the current / voltage detection circuit 6 as the signal input end of the control module 5, the output end of the comparator is connected to the signal input end of the main control MCU, and the first signal output end of the main control MCU is connected to the control signal input end of the micro water / air pump 7 as the first signal output end of the control module 5, wherein:

[0080] The threshold memory is used to store the threshold current / voltage;

[0081] The comparator is used to compare the current / voltage detected by the current / voltage detection circuit 6 with the threshold current / voltage, and output a corresponding level signal according to the comparison result;

[0082] The main control MCU is used to generate an opening instruction when the level signal is a preset level signal, so as to control the micro water / air pump 7 to turn on through the opening instruction.

[0083] Based on the above embodiments, in one embodiment, the threshold current / voltage includes a maximum threshold current / voltage A and a minimum threshold current / voltage B, wherein:

[0084] The maximum threshold current / voltage A is the current flowing through the sampling resistor 4 / the voltage across the sampling resistor 4 when the conductive wearable device 3 contacts the end of the first conductive member 2 close to the fixed balloon 102;

[0085] The minimum threshold current / voltage B is the current flowing through the sampling resistor 4 / the voltage across the sampling resistor 4 when the conductive wearable device 3 contacts the end of the first conductive member 2 away from the fixing balloon 102 .

[0086] Based on the above embodiment, in one embodiment, when the current / voltage detected by the current / voltage detection circuit 6 is greater than or equal to B and less than or equal to A, the comparator outputs a high level signal;

[0087] When the level signal output by the comparator is a high level signal, the main control MCU generates an opening instruction.

[0088] When the patient forcibly removes the catheter by himself, the conductive wearable device 3 worn on his hand will contact the first conductive member 2, and the current / voltage detected by the current / voltage detection circuit 6 will be between the minimum threshold current / voltage B and the maximum threshold current / voltage A. Therefore, when the current / voltage detected by the current / voltage detection circuit 6 is greater than or equal to B and less than or equal to A, it indicates that the patient has contacted the first conductive member 2 on the tube body 101 of the urinary catheter 100 and is ready to remove the catheter, then the comparator outputs a high-level signal, and the main control MCU generates an opening instruction to control the micro water / air pump 7 to start, so that the water or gas in the internal cavity of the fixed balloon 102 is discharged under the action of the micro water / air pump 7.

[0089] It should be noted that when the current / voltage detected by the current / voltage detection circuit 6 is not between the minimum threshold current / voltage B and the maximum threshold current / voltage A, the comparator outputs a low level, the main control MCU does not output, or outputs a shutdown command to control the micro water / air pump 7 to shut down.

[0090] When the conductive wearable device 3 on the patient's hand and the first conductive member 2 on the tube body 101 of the catheter 100 are connected through other conductive media (the conductive wearable device 3 and the first conductive member 2 are very likely to contact conductive media such as a metal bed at the same time), the conductive wearable device 3, the power module 1, the sampling resistor 4, the first conductive member 2 and the metal bed are connected in series in sequence to form a power-on circuit. At this time, the current / voltage detection circuit 6 will also detect the corresponding current / voltage. Since the resistance of the metal bed is very small, when the end of the first conductive member 2 on the tube body 101 of the catheter 100 close to the fixed balloon 102 contacts the metal bed, the current / voltage value detected by the current / voltage detection circuit 6 may also be between the minimum threshold current / voltage B and the maximum threshold current / voltage A, which may lead to an error in the judgment of the catheter removal action. In order to avoid this situation, based on the above embodiment, in one embodiment, the control system for preventing urinary tract damage caused by forced catheter removal also includes a second conductive member (not shown in the figure), which is covered on the surface of the metal part of the bed and is conductive to the metal part of the bed, wherein,

[0091] The resistance value of the second conductive member satisfies the following conditions:

[0092] When the conductive wearable device 3 is connected to the first conductive member 2 through the second conductive member, the resistance of the second conductive member connected to the power-on circuit is greater than the maximum value of the resistance between the two ends of the first conductive member 2.

[0093] In this way, when the conductive wearable device 3 and the first conductive member 2 touch the metal bed at the same time, they will touch the second conductive member on the surface of the metal bed. Since the second conductive member is made of a material with a relatively large resistance (when the conductive wearable device 3 is connected to the first conductive member 2 through the second conductive member, the resistance of the second conductive member connected to the power-on circuit is greater than the maximum value of the resistance between the two ends of the first conductive member 2), when the conductive wearable device 3 and the first conductive member 2 touch the second conductive member on the metal bed at the same time, the current / voltage value detected by the current / voltage detection circuit 6 will be less than or much less than the minimum threshold current / voltage B, thereby avoiding misjudgment of the extubation action and controlling the micro water / air pump 7 to turn on without having to turn on the micro water / air pump 7.

[0094] Specifically, the second conductive member may be a conductive adhesive layer made of a conductive material with relatively high resistance, such as conductive silicone rubber.
