Description
Technical Field
The invention belongs to the technical field of medical instruments.
Background
Parturition is a natural physiological process generally divided into three stages.
The first stage of labor begins with regular uterine contractions and ends with the full opening of the uterus. The second stage of labor is from the opening of the cervix until the fetus is delivered. Labor pain occurs primarily in the first and second stages of labor. The pain in the first phase of labor is mainly due to the progressive widening, shortening, thinning and enlargement of the lower uterine segment, cervical canal and uterine orifice caused by the descent of fetal head, the elongation and tearing of uterine muscle fibers, and the elongation of the ligamentum teres by strong traction. The second phase of pain mainly comes from the contraction of the uterus, the expansion of the lower uterus segment, the pressure of the fetal presenting part on the pelvic tissues and the expansion of the perineum.
The current methods of childbirth analgesia include both non-drug analgesia and drug analgesia. The non-drug analgesia comprises a mental comforting method, a respiratory method, water delivery and the like, and has the advantages of no influence on the labor process and the fetus, but poor analgesia effect; drug-induced analgesia is most widely recognized and used for intraspinal delivery analgesia. After the successful puncture of the lumbar intervertebral space, an anesthesiologist injects a small amount of local anesthetics or opioids into the vertebral canal, and places a thin catheter in the epidural space, one end of the catheter is connected with an electronic analgesia pump, the delivery is self-controlled by the puerpera according to the pain degree, and the analgesia pump can be continuously used until the delivery is finished.
The existing narcotic analgesic technology can not automatically adjust the concentration of the narcotic well, and the single narcotic concentration causes the analgesic effect in the second labor course not to be ideal.
In summary, it is an urgent technical problem to provide a method and a device for labor analgesia capable of adjusting drug concentration.

Examples
The invention provides a delivery analgesia method with adjustable drug concentration, which comprises the following steps:
step 1, arranging a normal saline bin filled with normal saline and a medicine bin filled with liquid medicine, wherein the medicine bin and the normal saline bin are respectively provided with a one-way valve, and the normal saline bin and the medicine bin are respectively communicated with a fusion bin through a conduit and a conduit;
step 2, collecting pressing force data detected by a hand-held pressure sensing assembly in a hand of a puerpera, collecting puerpera sound decibel data detected by a sound collecting assembly, and collecting uterine contraction pressure data detected by a uterine contraction monitoring assembly adhered to the abdomen of the puerpera;
step 3, when the pressing force data detected by the hand-held pressure sensing assembly is larger than a pressing force threshold value and/or the decibel data of the maternal sound acquired by the sound acquisition assembly is larger than a decibel threshold value, triggering the opening of the one-way valves on the first medicine bin, the second medicine bin and the normal saline bin, and closing the one-way valves on the first medicine bin, the second medicine bin and the normal saline bin after a first preset time; firstly, the dosage is increased, and then according to the actual situation, if the analgesic effect is not good, a doctor manually determines which valve to open to increase the drug concentration.
When the hand-held pressure sensing assembly detects that the pressing force data is smaller than the pressing force threshold value and/or the decibel data of the sound of the puerpera collected by the sound collection assembly is smaller than the decibel threshold value, the one-way valves on the first medicine bin, the second medicine bin and the normal saline bin are triggered to be opened, and the one-way valves on the first medicine bin, the second medicine bin and the normal saline bin are closed after second preset time.
The first preset time and the second preset time can be freely set. Optionally, the second preset time is shorter than the first preset time, so that when the hand-held pressure sensing assembly detects that the pressing force data is smaller than the pressing force threshold, and/or the sound decibel data of the puerpera collected by the sound collection assembly is smaller than the decibel threshold, the one-way valves on the drug bin and the saline bin are closed earlier.
When the uterine contraction pressure data detected by the uterine contraction monitoring component is greater than the uterine contraction pressure threshold value, closing the one-way valve on the third medicine bin; when the uterine contraction monitoring assembly detects that the uterine contraction pressure data is smaller than the uterine contraction pressure threshold value, the one-way valve on the third medicine bin is opened;
step 4, the normal saline and the anesthetic are moved to a fusion chamber through a catheter, and are converged in the fusion chamber to form mixed anesthetic liquid, and the mixed anesthetic liquid is infused into the vertebral canal of the lying-in woman through the catheter;
oxytocin is infused into the vein of the lying-in woman through a catheter;
and 5, repeating the step 3 and the step 4 to realize the adjustment operation of the drug concentration and the drug infusion amount.
The tolerance of each individual to pain is different, so that the pain level of the individual lying-in woman needs to be taken into consideration. In this embodiment, mainly realize through hand-held type pressure sensing subassembly and sound collection subassembly.
The lying-in woman presses the hand-held pressure sensing subassembly of placing in the hand, just can measure and obtain the pressing force data. The higher the pain level in delivery and the harder the parturient presses, the higher the pressing force data, and the higher the pain level in the parturient feels, and the higher the concentration or more anesthetic is needed for analgesia.
The parturient may yell because of pain while in production, and the sound collection assembly can measure sound decibels. The higher the decibel, the higher the pain level of the mother, and the higher the concentration of anesthetic or more needed to relieve pain.
The handheld pressure sensing assembly and the sound collection assembly are used for measuring, and the dosage of the anesthetic is adjusted according to the measuring result.
On the other hand, uterine contraction, namely regular uterine contraction, is an important monitoring index for clinical obstetric and gynecologic examination, the primary clinical sign of labor is regular contractions of the sense organs, which can cause the fetal heart rate to be accelerated or slowed, and the condition of uterine contraction can directly influence the movement of fetal heart and delivery.
The uterine contraction pressure is too low, which may adversely affect delivery and require an increase in oxytocin dosage. When the pressure of uterine contraction during the labor process is too high, the dosage of oxytocin needs to be properly reduced.
The uterine contraction monitoring assembly with the function of measuring the uterine contraction pressure is placed on the abdomen of a puerpera to measure, and then the dosage of oxytocin is adjusted according to the measuring result.
During the delivery process, the three data are continuously measured, the valve is controlled according to the result, the amount of the anesthetic and the physiological saline entering the fusion bin is controlled, and meanwhile, the dosage of the oxytocin infused into the vein can be controlled.

Oxytocin in the third cartridge does not enter the fusion cartridge but is infused through an infusion catheter 290 connected at the other end to the patient's vein.
In specific implementation, the number of the medicine bins can be increased or decreased according to actual needs.
As shown in fig. 1, the fusion chamber 270 provides a space for mixing the anesthetic and the saline uniformly to form a mixed liquid.
The drug bin 210 and the physiological saline bin 240 are both provided with one-way valves 250, and the one-way valves 250 can only pass in one way, so that liquid backflow is avoided.
The injection assembly 200 includes conduits for communicating the saline reservoir 240 and the drug reservoir 210, respectively, to the fusion chamber 270. The conduits include a first conduit 220, a second conduit 260, and a fusion conduit 280.

The pressing force detection unit is provided below the button 310 by way of example and not limitation.
Optionally, the handle 330 is provided with a plurality of indentations 320. By way of example and not limitation, the number of indentations 320 is three, and the width of the indentations 320 and the lateral distance between the indentations and the width of the fingers match, making the grip 330 more convenient for a parturient to grasp.
In addition to the example shown in fig. 3, the entire hand-held pressure sensing unit 300 may be provided as an elastic structure, and the pressing force detection unit may be provided at a plurality of positions. Thus, when the puerpera feels pain, the hand-held pressure sensing assembly 300 in the hand is squeezed, and the average value of the data measured by the plurality of pressing force detecting units can also be used as the measure of the pain degree.
As shown in fig. 4, the labor analgesia device 100 with adjustable drug concentration provided by the invention comprises a uterine contraction monitoring assembly 400 for detecting the uterine contraction pressure data of the abdomen of a parturient during uterine contraction.
The uterine contraction monitoring assembly 400 is a pressure sensor, and a detection element is arranged in the uterine contraction monitoring assembly and can detect uterine contraction pressure.
The uterine contraction monitoring assembly 400 is provided with an adhesive layer 410 which can be adhered to the abdomen of the parturient. Optionally, a release layer is arranged on the adhesive layer, and the release layer contains substances which are not sticky, so that the adhesive layer 410 can be protected, and the adhesive layer is convenient to tear.
The uterine contraction monitoring assembly 400 further comprises a fetal heart monitoring unit 420 for detecting the fetal heart rate.
Optionally, the fetal heart monitoring unit 420 is configured to alarm when the fetal heart rate exceeds a preset normal range value. The alarm mode is mainly through sound alarm or flash light alarm or the combination of the two.
The invention provides a drug concentration adjustable childbirth analgesia device 100, which comprises a sound collection assembly 900, as shown in fig. 7, for collecting the sound decibels of a puerpera. The components include a microphone 910, and a display 920 to display data.
Before the delivery starts, the sound of the lying-in woman is sampled and identified. For example, a puerpera shouts for a few hours, records the voice, and identifies and records the voice characteristics. Thus, even if certain external environment sound interference exists in the subsequent delivery, the voice of the lying-in woman can be identified and tracked. In practice, the sound collection assembly 900 may be placed near the mouth of the pregnant woman, such as at the head of a bed, or at the chest, or in the hand of the pregnant woman.
The injection assembly 400 also includes a vent valve 600, as shown in fig. 5.
The exhaust valve 600 is connected to the infusion pump 800 through the infusion tube 290 at one end and connected to the infusion tube 290 at the other end for exhausting the gas in the liquid medicine.
As shown in fig. 6, the childbirth analgesia device 100 with adjustable drug concentration further includes a control assembly 700.
The hand-held pressure sensing assembly 300, the sound collection assembly 900 and the uterine contraction monitoring assembly 400 are all connected to the control assembly 700 through wireless communication.
The control assembly includes an identification module and an activation module, which are disposed inside the control assembly by way of example and not limitation.
The identification module can match a preset drug administration scheme corresponding to a puerpera state database according to puerpera sound decibels acquired by the sound acquisition assembly and pressing force data acquired by the hand-held pressure sensing assembly; the starting module can trigger the one-way valve of the corresponding first medicine bin and/or second medicine bin to be opened according to the medicine feeding scheme, and trigger the one-way valve of the physiological saline bin to be opened.
As shown in fig. 1, the catheter is provided with a flow sensor 500 for detecting the amount of liquid flowing out of the drug chamber and the physiological saline chamber; when the flow sensor detects that the amount of liquid is equal to a preset threshold value, the control component triggers the corresponding one-way valve of the first medicine bin or the second medicine bin to be closed, and triggers the one-way valve of the physiological saline bin to be closed.
The preset puerpera state database stores a list of pain levels corresponding to the pressing force data and/or the sound decibel data, different pressing force data and/or sound decibel data correspond to different pain levels, and different pain levels correspond to different optimized medicines. The control module matches pain levels according to the collected data information and selects corresponding dosing regimens in the database according to the pain levels.
For example, the pain level is 10 grades, the priority of 1-5 is to increase the dosage, and the pain level is 6-10 to increase the drug concentration, depending on the preset maternal status database.
In the pain level of 1-5, the control module selects one or more anesthetic drugs suitable for the current puerperal state according to a preset drug administration scheme to perform constant concentration drug administration. This operation is mainly applicable to the early stage of labor. The flow is monitored by the flow sensor 500, and the control unit 700 closes the corresponding one-way valve 250 when the flow sensor detects that a predetermined amount of anesthetic and saline has left the corresponding chamber and entered the catheter. Thus, the amount of anesthetic entering the fusion chamber 270 and the amount of physiological saline for dilution are fixed, and the concentration of the mixed drug solution is fixed. With a fixed concentration of the drug solution, the control unit controls the amount of drug administered in conjunction with an infusion pump 800 disposed in an infusion tube 290 as shown in fig. 5.
And for the database, the user can perform custom editing in the later period according to clinical needs. Similarly, the preset threshold may be later adjusted and set on the control module 700 to increase or decrease the initial concentration of the anesthetic or anesthetic blends being dispensed.
As labor progresses, a fixed concentration of anesthetic may not meet the analgesic requirements well. In this case, the control module can be used in combination with other modules to adjust the concentration of the drug.
When the pressing force data detected by the hand-held pressure sensing assembly 300 is larger than a pressing force threshold value and/or the decibel of the sound of the puerpera collected by the sound collection assembly is larger than a decibel threshold value, the control assembly triggers the one-way valves on the first medicine bin, the second medicine bin and the normal saline bin to be opened, and closes the one-way valves on the first medicine bin, the second medicine bin and the normal saline bin after first preset time.
When the pressing force data is larger than the pressing force threshold value and/or the sound decibel of the puerpera is larger than the decibel threshold value, the personal pain feeling degree of the puerpera is higher. At this time, the one-way valves 250 of the first drug storage 211 and the second drug storage 212 are opened to allow more anesthetic to enter the fusion storage 270, and the one-way valve 250 of the saline storage 240 is opened to increase the amount of saline entering the fusion storage 270. Increasing the drug dose keeps the concentration constant.
In actual use, after analgesia is performed for a period of time, the first drug bin 211, the second drug bin 212 and the normal saline bin 240 can be closed in a manually synchronous delay mode.
Alternatively, the control unit may automatically close the first cartridge 211, the second cartridge 212, and the saline cartridge 240 after a preset time.
When the pressing force data detected by the hand-held pressure sensing assembly 300 is smaller than the pressing force threshold value and/or the decibel of the sound of the puerpera collected by the sound collection assembly is smaller than the decibel threshold value, the control assembly triggers the one-way valves on the first medicine bin, the second medicine bin and the normal saline bin to be opened, and closes the one-way valves on the first medicine bin, the second medicine bin and the normal saline bin after the second preset time.
The first preset time and the second preset time may be freely set. Optionally, the second preset time is shorter than the first preset time, so that when the hand-held pressure sensing assembly detects that the pressing force data is smaller than the pressing force threshold, and/or the sound decibel data of the puerpera collected by the sound collection assembly is smaller than the decibel threshold, the one-way valves on the drug bin and the saline bin are closed earlier.
When the pressing force data is smaller than the pressing force threshold value and/or the sound decibel of the puerpera is smaller than the decibel threshold value, the personal pain feeling degree of the puerpera is not high. At this time, the one-way valves 250 of the first and second cartridges are opened and the one-way valve 250 of the saline cartridge is opened to maintain a constant concentration and a constant administration rate. Drug infusion was maintained at a fixed dosing dose of concentration.
In actual use, after analgesia is performed for a period of time, the first drug bin 211, the second drug bin 212 and the physiological saline bin 240 can be closed manually.
Alternatively, the control unit may automatically close the first cartridge 211, the second cartridge 212, and the saline cartridge 240 after a preset time. The preset time may be shorter than the preset time when the pressing force data is greater than the pressing force threshold, and the closing time is earlier.
When the uterine contraction pressure data detected by the uterine contraction monitoring component 400 is greater than the uterine contraction pressure threshold value, the control component triggers the one-way valve 250 on the third medicine bin 213 to close.
When the uterine contraction pressure data is larger than the threshold value, the uterine contraction pressure is larger, the one-way valve 250 of the third medicine bin 213 is closed, and the intravenous infusion dosage of oxytocin is reduced.
When the uterine contraction pressure data detected by the uterine contraction monitoring component 400 is smaller than the uterine contraction pressure threshold value, the control component triggers the one-way valve 250 on the third medicine bin 213 to open.
When the uterine contraction pressure data is smaller than the threshold value, the uterine contraction pressure is smaller, and the one-way valve 250 of the third medicine bin is opened to improve the intravenous infusion dosage of oxytocin.
The pressing force threshold, decibel threshold and uterine contraction threshold can be preset when leaving the factory, and can also be adjusted in the later period through the control assembly 700 by combining with clinical actual needs.
As shown in fig. 1 and 5, the catheter is provided with a flow sensor 500, which includes an alarm module and a detection module, wherein the detection module is used for detecting the total amount of the liquid medicine in a unit hour; the alarm module triggers an alarm when the total amount of the liquid medicine detected by the detection module in a unit hour is larger than a liquid medicine threshold value.
The flow sensor 500 is disposed on the first conduit 220, the second conduit 260, the fusion conduit 270 and the infusion conduit 290, and the control assembly 700 is capable of controlling the total injection amount of the drug per unit time. The flow sensor 500 is connected to the control module 700 via wireless communication to monitor the flow rate of the liquid in each catheter, and the data is transmitted to the control module, which calculates the total amount of the liquid medicine entering the infusion catheter 290 in a unit time. When the total amount of fluid entering the infusion conduit 290 per unit time reaches a predetermined upper limit, the control module closes all of the one-way valves 250. At this time, the hand-held pressure sensing assembly 300, the sound collection assembly 900 and the uterine contraction monitoring assembly 400 are all locked, i.e., the collected data does not trigger the control assembly 700 to open any one-way valve 250, so as to ensure that the total amount of the drug entering the infusion catheter 290 per hour, i.e., the total amount of the drug finally entering the parturient via the infusion catheter 290 per unit time, is within the normal preset value range.
After this unit time period has elapsed, the lock is released, following the method steps described above, and the operation cycle continues into the next time period.
As shown in fig. 2 and 5, the infusion pumps 800 are disposed on the infusion tube 290 connected to the third cartridge 213 and the infusion tube 290 connected to the fusion cartridge 270; the infusion pump 800 clamps the infusion tube 290 for adjusting the flow rate of the liquid medicine; the infusion pump 800 is connected to the control unit 700 via wireless communication.
The infusion pump 800 is a clinical instrument that can accurately control the number of infusion drops or the flow rate of infusion, ensure the uniform speed of the drug and ensure the accurate amount of the drug entering the body of the patient. The infusion pump 800 is arranged to control the flow rate of the liquid medicine infused into the vertebral canal of the lying-in woman.
On the other hand, the infusion pump 800 acts on the infusion catheter 290, and in cooperation with the control unit 700, the total amount of the drug per unit time entering the body of the parturient through the infusion catheter 290 in a unit hour can be monitored and controlled, so as to ensure that the infusion amount of the drug per unit time is within the normal preset value range.
As shown in fig. 6, the control assembly 700 includes a touch screen 710 for displaying an interactive interface. The data measured by the hand-held pressure sensing assembly 300, the uterine contraction monitoring assembly 400, the flow sensor 500 and the infusion pump 800 are displayed on the touch screen 710 for reference by the doctor.
The physician may also make various option settings via the touch screen 710. For example, during parturient delivery, the doctor may select an automatic control mode in which the device 100 automatically adjusts the drug dose or drug concentration according to the method steps described above.
According to the information that hand-held pressure sensing subassembly and sound collection subassembly gathered, the control module adjusts medicine dosage and administration concentration through controlling each check valve and transfer pump, can be the improvement medicine concentration, also can increase the medicine volume under the prerequisite that keeps the concentration invariable. The control component is matched with the flow sensor and the infusion pump, so that the upper limit of the total drug administration amount in unit time can be controlled, and the drug infusion amount in unit time is ensured to be within a normal preset value range.
The physician can also select a manual mode, in which the physician can manually control the one-way valves 250 of the respective chambers and the infusion pump 800 acting on the infusion tube 290 through the touch screen 710 to generate drugs of different concentrations in the fusion chamber 270, increase the concentration of the single drug, adjust the flow rate of the drug and adjust the drug infusion amount, in combination with the actual progress of the labor of the parturient and the uterine contraction pressure and pain.

step 3, when the pressing force data detected by the hand-held pressure sensing assembly is larger than a pressing force threshold value and/or the decibel data of the maternal sound acquired by the sound acquisition assembly is larger than a decibel threshold value, triggering the opening of the one-way valves on the first medicine bin, the second medicine bin and the normal saline bin, and closing the one-way valves on the first medicine bin, the second medicine bin and the normal saline bin after a first preset time;
when the hand-held pressure sensing assembly detects that the pressing force data is smaller than the pressing force threshold value and/or the decibel data of the maternal sound acquired by the sound acquisition assembly is smaller than the decibel threshold value, the one-way valves on the first medicine bin, the second medicine bin and the normal saline bin are triggered to be opened, and the one-way valves on the first medicine bin, the second medicine bin and the normal saline bin are closed after a second preset time;
when the uterine contraction pressure data detected by the uterine contraction monitoring component is greater than a uterine contraction pressure threshold value, closing the one-way valve on the third medicine bin; when the uterine contraction monitoring assembly detects that the uterine contraction pressure data is smaller than the uterine contraction pressure threshold value, the one-way valve on the third medicine bin is opened;
step 4, the normal saline and the anesthetic are moved to a fusion chamber through a catheter, and are converged in the fusion chamber to form mixed anesthetic liquid, and the mixed anesthetic liquid is infused into the vertebral canal of the lying-in woman through the catheter; oxytocin is infused into the vein of the lying-in woman through a catheter;
and 5, repeating the step 3 and the step 4 to realize the adjustment operation of the drug concentration and the drug infusion amount.
