Description

Intelligent injection system and method

Technical Field

The invention relates to the technical field of medical instruments, in particular to an intelligent injection system and method for a parturient in a childbirth process.

Background

In the process of natural childbirth of a puerpera, in order to relieve uterine contraction and labor pain during childbirth of the puerpera, epidural childbirth analgesia is usually required, namely, an analgesic drug or anesthetic is injected into an epidural space of the puerpera through an epidural catheter to achieve the purpose of relieving the pain of the puerpera. However, the existing administration is crude and only the same dose of analgesic drug is administered continuously or intermittently.

Due to the different abilities of different women to tolerate pain, a constant amount of drug is just for some people and too much or too little for some people. Therefore, the existing administration mode in empirical medicine ignores the pain experience of the puerpera and the pain mechanism that the pain gradually increases along with the increase of the uterine orifice of the puerpera, and can not meet the requirement of analgesia in the whole labor process. On the other hand, if the amount of anesthetic injected is too large, it tends to cause adverse effects on the newborn infant, in addition to lengthening the birth process, with irreparable consequences.

Therefore, in the process of parturient delivery, the existing epidural administration technology cannot meet the individual difference and individualized and variable analgesic requirements generated in different stages in the process of parturient delivery, and cannot comprehensively and effectively play the analgesic effect.

Fig. 1 is a schematic block diagram of an intelligent injection system in accordance with an embodiment of the present invention. Referring to fig. 1, the intelligent injection system 10 of this embodiment includes a feedback parameter receiving module 11, a calculating module 12 and an injection module 13. The feedback parameter receiving module 11 is configured to receive a feedback parameter input by a user, where the feedback parameter includes a pain level and a size of a uterine orifice.

The pain level is used to characterize the degree of pain that a parturient subjectively experiences during the production process. In an embodiment of the invention, the pain level as one of the feedback parameters comprises a maternal-determined VAS (visual analogue Scale) score, which can score the pain level experienced by the woman. Illustratively, during parturient delivery, the VAS score can be determined by the parturient himself based on the pain experienced by him/herself, such as a score of 0,1,2, …,10, where 0 indicates no pain and 10 indicates the most intolerable intense pain, with increasing pain perception from 0 to 10. The acquisition mode of the VAS score is not limited, for example, a nurse can show a score scale to the puerpera, and the puerpera can orally select the score scale; or by the parturient making a selection through an application on a mobile terminal, such as a cell phone, etc.

In some embodiments, the parameters of the pain level may be automatically obtained by the facial expression of the parturient. Illustratively, the facial expression of the parturient is acquired by an imaging device (such as a camera) during the parturition process, and the pain level corresponding to the facial expression of the parturient can be obtained by analyzing the facial expression of the parturient.

In another embodiment of the invention, the pain level may be characterized by some objective measurement means. The pain level is determined, for example, by measuring the amount of pinching force applied by the parturient to the hand grip, with a greater pinching force indicating a higher pain level.

In an embodiment of the invention, the parameter of the size of the uterine orifice comprises the actual size of the uterine orifice measured manually. Illustratively, during parturient delivery, the size of the uterine opening can be assessed by the midwife by examining the actual size of the maternal uterine opening, e.g., by assessing 0,1,2, …,10 cm, etc., 1-10 fingers, etc. In the embodiment of the present invention, the size of the uterine orifice may be a result of the judgment made by the midwife by experience, or a result measured by using a related instrument, such as an ultrasound instrument, an imaging device, and the like. The invention does not limit the measuring method of the uterine orifice size.

It should be noted that since labor has a long process, the intelligent injection system 10 of the present invention can continuously obtain feedback parameters from the user during the process. The invention does not limit the frequency of the feedback parameters input by the user. In some embodiments, the frequency of inputting the feedback parameters to the feedback parameter receiving module 11 may be set by the user himself. For example, the size of the uterine opening and the level of pain are inputted every 30 minutes. The input frequency of the two parameters of the uterine orifice size and the pain level can be the same or different.

As shown in fig. 1, the calculating module 12 is configured to receive the feedback parameters, i.e. the pain level and the size of the uterine orifice, from the feedback parameter receiving module 11, and calculate the injection mode and the injection parameters according to the feedback parameters.

In an embodiment of the present invention, the calculation method of the calculation module 12 is to calculate the injection mode and the injection parameters according to a preset lookup table. For example, the pattern of the lookup table may correspond to a selection of a specific injection pattern and a specific value and/or variation of the injection parameter in the specific injection pattern for each pain level, and each of the size and/or range of the ostium corresponds to a selection of a specific injection pattern and a specific value and/or variation of the injection parameter in the specific injection pattern.

It will be appreciated that the present invention is not limited to the form of the lookup table described above, and that different types of lookup tables may be used depending on the actual maternal delivery needs or injection pattern needs. Even a comprehensive lookup table of the comprehensive pain level and the size of the uterine orifice can be designed on the basis of separately and respectively designing the lookup tables of the pain level and the size of the uterine orifice, and the adjustment and the modification of various lookup tables belong to the spirit and the scope of the invention.

In an embodiment of the present invention, the injection mode may include an intermittent injection mode and a continuous injection mode. Wherein, in the intermittent injection mode, the injection parameters comprise injection interval time and injection volume of each time; in the continuous injection mode, the injection parameters include the hourly injection volume.

Illustratively, the intermittent injection mode may be a programmed intermittent Epidural injection mode (PIEB). In the PIEB mode, the injection parameters calculated by the calculation module 12 as shown in fig. 1 include an Interval Time (Interval Time) and a Volume per injection (Bolus Volume). For example, the injection interval time can be any value in the range of 1-60 minutes in min (minutes); the volume per injection, in mL, can be optionally varied from 0, 0.5, 1, 1.5, …,10 mL. According to the intermittent injection mode, after the injection module 13 performs one injection per injection volume, the injection interval is stopped, and then the next injection per injection volume is performed. The infusion rate, i.e. the total amount injected per hour, e.g. between 200 and 500 mL/hour, can be derived from the injection interval time and the volume of each injection.

The above numerical ranges are merely exemplary and are not intended to limit the specific ranges of injection parameters of the present invention.

For example, the Continuous injection mode may be a Continuous Epidural Injection (CEI). In the CEI mode, the injection parameter calculated by the calculation module 12 shown in fig. 1 is the injection volume per hour, which can also be understood as the injection rate, for example, in mL/hour. It should be noted that the continuous injection mode is not limited to the injection module 13 performing the injection continuously, but may include the injection module 13 performing the injection at a constant speed according to a certain frequency, so that the injection volume in one hour reaches the set injection volume per hour.

It is to be understood that the present invention is not limited to the simultaneous use of the intermittent injection mode and the continuous injection mode described above in all embodiments. In practical applications, only one of the injection modes can be selected during a certain period of time of parturient delivery, or one of the injection modes is taken as a main injection mode and the other injection mode is taken as an auxiliary injection mode, and various selections, matching and adjustments of the injection modes belong to the spirit and the scope of the invention.

In an embodiment of the present invention, each injection volume in the injection parameters may include a plurality of injection volume gears, and the plurality of injection volume gears correspond to different degrees of the uterine orifice size. It is understood that as labor progresses, the size of the ostium gradually increases. Generally speaking, the pain perception of the parturient will also be more and more intense, requiring larger doses of analgesic drug. In this embodiment, corresponding injection volume gears, such as 0,1,2, …, and 10 gears, may be set according to the actual size of the uterine opening.

In an embodiment of the present invention, after the current injection volume gear is determined according to the size of the uterine orifice, the current injection volume gear can be adjusted according to the current pain level of the parturient. The size of the uterine orifice is an objective measure, and is generally proportional to the level of pain. However, the size of the uterine orifice and the pain sensation experienced by the individual are different for different women. Therefore, in order to realize fine and automatic analgesia administration on the lying-in woman, the injection volume gear is adjusted by adopting the personalized VAS score of the lying-in woman. In some embodiments, the adjustment includes increasing or decreasing the current injection volume gear. In some embodiments, adjusting the current injection volume gear according to the pain level may further comprise: adjusting the current injection volume gear to one of a plurality of injection volume gears. For example, when the VAS score of the parturient is high, the injection volume gear can be directly adjusted to a higher gear if only one gear of the injection volume gear is increased and cannot meet the current analgesic needs.

Referring to fig. 1, the injection module 13 is used for injecting the medicine to the injection subject (i.e., the parturient) according to the calculation result of the calculation module, i.e., the injection mode and the injection parameters described above. It can be understood that the intelligent injection system 10 shown in fig. 1 is an integral body, and the injection mode and injection parameters of the injection module 13 are adjusted in real time according to the input feedback parameters, so as to realize the refined and automatic pain-relieving administration control for the puerpera.

In an embodiment of the invention, the injection module 13 may comprise a first injection channel adapted to inject a first medicament to an injection subject and a second injection channel adapted to inject a second medicament to the injection subject. The present invention is not limited to the type and action of the first drug and the second drug, and the first drug and the second drug may be the same or different. Neither the first drug nor the second drug is limited to only one drug, and may be a combination of multiple drugs or solutions, respectively. According to this embodiment, a combined use of different types of drugs during childbirth of a parturient can be achieved.

In a preferred embodiment of the present invention, the first drug and the second drug are both labor analgesia drugs, and the specific components of the first drug and the second drug are different.

In an embodiment of the present invention, the calculating module 12 calculates the injection mode and the injection parameters of the first injection channel according to the feedback parameters received by the feedback receiving module 11, i.e. the pain level and the size of the uterine orifice.

In an embodiment of the present invention, the second injection channel may inject the second medicine to the injection subject at fixed injection intervals and per injection volume.

The injection modes of the first injection passage and the second injection passage are not limited, and the injection modes of the first injection passage and the second injection passage can be the same or different.

In another embodiment of the present invention, the injection mode of the injection module 13 shown in fig. 1 of the present invention may be that when the first injection channel stops injecting the first medicine to the injection subject, the second injection channel injects the second medicine to the injection subject.

In an embodiment of the present invention, based on the above-described intelligent injection system 10 shown in fig. 1, an intelligent injection system of the present invention may further include a prompting unit 14, and the prompting unit 14 may issue a prompt and/or alarm according to the change of the pain level received by the feedback parameter receiving module 11 shown in fig. 1.

More specifically, the pain level may be compared with a threshold value, and when the pain level reaches or exceeds the threshold value, the prompting unit 14 may issue a prompt and/or alarm, such as an audible or written message, to an operator assisting the delivery of the parturient, such as an anesthesiologist, a midwife, and an obstetrician, so as to enable the medical staff to perform appropriate intervention and treatment at the first time.

It can be understood that, on the basis that the above-mentioned prompt unit 14 can give an alarm according to the feedback parameter, a person skilled in the art can also set the prompt unit 14 to give an alarm when each element of the intelligent injection system of the present invention is abnormal, for example, the injection pressure of the injection module is abnormal, the injected medicine is exhausted, etc. Since the prompting unit 14 is not the focus of the present invention, it is not expanded herein, but the intelligent injection system according to the present invention and the setting and adjustment of the prompting unit 14 for specific prompting information are all within the spirit and scope of the present invention.

The above is a detailed description of each part of an intelligent injection system according to a first embodiment of the present invention. It will be appreciated that an intelligent injection system of the present invention may be implemented with the necessary software and hardware, as well as communications between various parts of the system, as well as databases and servers. Accordingly, both hardware devices comprising the intelligent injection system of the present invention and software systems implementing the functionality of the modules of the intelligent injection system of the present invention are within the intended scope of the present invention.

For example, in an embodiment of the present invention, the feedback parameter received by the feedback parameter receiving module in the intelligent injection system of the present invention may be obtained through an external input device outside the intelligent injection system, so that the puerpera and the medical care personnel may conveniently input the pain level parameter and the uterine orifice size parameter, and the external device may be wirelessly connected to the intelligent injection system of the present invention and perform necessary information interaction. For example, the external input device is a mobile terminal.

For another example, the above-mentioned prompting unit 14 may establish a connection relationship with a client device used by the medical staff, and the client device is equipped with corresponding client software for receiving the prompt and/or alarm information sent by the prompting unit 14.

It is to be understood that the use of hardware and software, wired and/or wireless communication between the components, etc. is not essential to the invention and is not to be construed as being herein disclosed. It is within the spirit and scope of the present invention to select and adjust the hardware and software devices and communication tools for implementing the intelligent injection system of the present invention.

Fig. 2 is a schematic block diagram of one implementation of a smart injection system of an embodiment of the present invention. The intelligent injection system 20 shown in fig. 2 is a specific implementation based on the intelligent injection system 10 shown in fig. 1, and therefore, the description of the intelligent injection system 10 shown in fig. 1 is suitable for the description of the intelligent injection system 20 shown in fig. 2.

In the embodiment shown in fig. 2, the intelligent injection system 20 includes a feedback parameter receiving module 21, a calculation module 22, and an injection module 23. Wherein the feedback parameter receiving module 21 receives feedback parameters including pain level and uterine orifice size. The calculation module 22 is configured to receive the pain level and the size of the uterine cavity from the feedback parameter receiving module 21, and calculate an injection mode and an injection parameter according to a preset lookup table. The injection module 23 comprises a first injection channel 231 for injecting the first medicament a and a second injection channel 232 for injecting the second medicament B. The first injection channel 231 and the second injection channel 232 have a linkage relationship, that is, after the first injection channel 231 performs one injection, the intelligent injection system 20 instructs the second injection channel 232 to perform one injection. The injection mode of the first injection channel 231 and the second injection channel 232 are both the PIEB mode, however, the injection parameters of the first injection channel 231 may vary as the feedback parameters received by the intelligent injection system 20 vary; the injection parameters of the second injection passage 232 are relatively fixed. Wherein the calculation module 22 calculates injection parameters of the first injection channel 231 according to the pain level and the size of the uterine orifice, the injection parameters including an injection interval time (min) and a volume per injection (mL). In the implementation shown in fig. 2, the injection interval time of the first injection channel 231 is set to be 30min, and each injection volume for injecting the first medicine a has 6 steps, which can be selected from 0.25mL at 1 step, 0.5mL at 2 steps, 0.75mL at 3 steps, 1.0mL at 4 steps, 1.25mL at 5 steps and 1.5mL at 6 steps. The second injection channel 232 has a volume of 4ml per injection and an injection interval of 30 min.

In the implementation shown in fig. 2, the size of the uterine orifice corresponds to 1-6 gears of the injection capacity of the first injection channel 231. The first table below is a lookup table of correspondence between the size of the uterine orifice and the injection parameters in this implementation. As shown in table one, each uterine orifice size corresponds to the injection interval time and the injection volume gear of each injection volume of the first injection channel 231 and the second injection channel 232. If a uterine orifice size parameter of 3cm is obtained, the calculation module 22 searches the first lower table to obtain that the injection interval time of the first injection channel 231 is set to be 30min, and the injection volume gear is 2 gears, namely 0.5 mL; and the injection interval time of the second injection passage 232 is 30min, and the injection volume is 4mL each time.

Table-uterus mouth size-injection parameter corresponding relation lookup table

Usually during the whole process of labor, the uterus opening from 0 to 10 means the process of the cervical dilatation phase from the beginning to the full opening, also called the first labor. According to table one, the second injection channel 232 injects the second medicine B to the injection subject at a fixed injection interval time (30min) and injection volume per one time (4mL) except for an interval in which the uterine opening size is [9,10] cm. When the uterine orifice size is [9,10] cm, the injection interval time of the second injection passage 232 is changed to 15min, and the volume per injection is changed to 2 mL. This is because when the size of the uterine opening is [9,10] cm, the end of the first labor is approached, and therefore, the dosage and interval of the second medicament B need to be adjusted to facilitate the subsequent delivery period of the fetus (second labor) and the placenta (third labor).

In the implementation shown in fig. 2, the first injection channel 231 and the second injection channel 232 are linked, i.e. after the first injection channel 231 injects the first medicine a, the second injection channel 232 injects the second medicine B immediately. Therefore, as shown in Table one, the injection interval time of the first injection channel 231 and the second injection channel 232 is 30min except for the interval in which the uterine opening size is [9,10] cm.

In the implementation shown in fig. 2, the above-mentioned finding of the corresponding injection parameter based on the uterine orifice size is taken as the main form, and it can be understood that the calculation module 22 performs the above-mentioned finding calculation as table one based on the information of the uterine orifice size parameter, and then performs the calculation of the pain level selected by the parturient.

In the embodiment of the invention, the measurement of the size of the uterine orifice and the acquisition of the VAS score can be performed synchronously or asynchronously. For example, the case of synchronization: the size of the uterine opening is measured and the VAS score is given to the parturient at the same moment, and the size and VAS score are given again after the same interval, e.g. 30 min. Asynchronous case: the midwife measures the size of the uterine opening according to the interval time of 30min, and performs VAS scoring on the parturient in response to the requirement of the parturient, so that the time points for obtaining the VAS scoring can be randomly interspersed in the whole labor process; or the midwife may score the woman for VAS at another interval, e.g., 10min, different from the interval at which the size of the ostium is measured. This is suitable for the case of a high pain level, where the medication needs to be adjusted in time according to the pain level, i.e. the injection volume level determined according to the size of the uterine orifice is adjusted in time according to the VAS score. In one embodiment, the administration of the drug may be specifically adjusted according to the pain level versus injection parameter correspondence shown in table two below.

As shown in table two below, the pain level in this implementation is a maternal-determined VAS score. The intelligent injection system 20 increases or decreases the injection volume steps or adjusts to a particular injection volume step based on the obtained VAS score value. Table two below may be understood as the adjustment of the injection parameters for the first injection channel 231 and the second injection channel 232 after obtaining a known calculation result calculated according to the lookup of table one above. In table two, an item for setting whether to inject the medicine immediately after obtaining the VAS value is included in the injection parameters of the first injection channel 231 and the second injection channel 232, which is suitable for a case when the VAS score is not synchronized with the uterine opening size measurement. And the injection parameters for the first injection channel 231 also include settings for "this injection volume" and "next injection volume".

For example, when the midwife measures that the size of the uterine opening is 3cm at a certain first time t1, the calculation module 22 determines that the injection capacity gear of each injection capacity of the first injection channel 231 is 2 th gear according to the table one, the first injection channel 231 injects the first medicine a to the parturient according to the injection capacity gear, and the second injection channel 232 injects the second medicine B to the parturient, and the injection capacity of the second medicine B is 4 mL. The following is illustrated in two cases:

in the first case: at the 10 th minute after the first time t1, i.e., at time t1+10, the midwife has performed one VAS score on the parturient, where the obtained VAS score is 4, although 20 minutes remain from the next injection from the first injection channel 231, according to table two, the first injection channel 231 immediately injects the first medicine a one time, and the injection volume is the current injection volume step plus 1 step, i.e., 3 steps; after 30 minutes from this time, i.e., at time t1+40, the first injection channel 231 performs the next injection, and the next injection volume is shifted up by 1, i.e., 4, on the basis of the current injection volume shift position. At time t1+10, after the first medicine A is injected through the first injection path 231, the second injection path 232 injects the second medicine B, and the injection volume per time is unchanged and still 4 mL.

In the second case: at the 10 th minute after the first time t1, i.e. at time t1+10, the midwife performed a VAS score on the parturient, which was 1, according to table two, the first injection channel 231 did not require the injection of the first drug a immediately after the VAS value was obtained, so the "injection of drug immediately after VAS value" setting is "no"; the injection volume is "/", i.e. no injection is needed; the "injection interval" is constant, i.e. still 30 min; the "next injection volume" is "minus 1 st gear", i.e. at the next injection time, i.e. at time t1+30, the injection volume gear of the first injection channel 231 is 1 st gear. The second injection channel 232 also does not need to inject the second medicament B immediately, with a corresponding per injection volume of "/".

TABLE two pain LEVEL-INJECTION PARAMETER CORRESPONDING TABLE

In table two, when the VAS value is "8 or 9", the present injection volume of the first injection channel 231 is "6 th", which means that the injection volume gear is adjusted to 6 th gear regardless of the present injection volume gear. The corresponding "next injection volume" is "shift 3 up". When the next injection is performed, if the ratio of 3 plus the current injection gear exceeds the 6 th gear of the highest gear, the next injection capacity is the 6 th gear of the highest gear. For the other cases in Table two, where the highest gear may be exceeded, the injection volume is set to the highest gear.

Since the intelligent injection system 20 of the present invention uses the two parameters of the uterine orifice size and the pain level as the basis for calculating the injection mode and the injection parameter, the shift is not fixed after the adjustment of the injection volume shift is made according to the VAS value as shown in table two, and in the subsequent process, the injection volume shift may be adjusted according to the uterine orifice size, for example, the next measurement of the uterine orifice size is 3.5cm, and the injection volume shift is set to 2 according to table one. According to table two, when the VAS value obtained is "8 or 9", the next injection capacity step is adjusted to 2+3 — 5.

Therefore, in combination with tables one and two, the injection parameters can be adjusted in time in combination with the objective stoma size and the subjective pain level of the parturient, and in combination with the first injection channel 231 and the second injection channel 232, an optimized analgesia regime is given to the parturient.

In some embodiments, the maternal is scored every 30min when the VAS score is less than or equal to 6, and every 15min when the VAS score is greater than 6.

It should be noted that tables one and two are only examples and are not exhaustive of the correspondence between the size of the uterine cavity, the pain level and the injection parameters in the intelligent injection system 20 of the present invention. It is within the scope of the present invention that the skilled person can make various changes in the above table one and table two, including the modification of the injection mode and injection parameters of the drug injection channel according to the different drugs used.

Further, the implementation shown in fig. 2 further includes a prompt unit 24, and the prompt unit 24 may issue a prompt and an alarm when the VAS score reaches 8 points or more. And if 2 VAS scores reach 8 points or more within 15-20 minutes, alarming. The invention does not limit the specific form of the alarm, and can adopt any mode which can draw attention, such as sound, light, pictures and the like.

When the VAS score reaches more than 6 points, the time interval of the VAS score is reduced to 15min, and the prompting unit 24 prompts the parturient to perform the next VAS score 15min after the second injection channel 232 performs one injection task. When the VAS score is less than or equal to 6, the prompting unit 24 can be used for prompting the parturient to perform the VAS score every 30 min.

It is understood that the prompt issued by the prompting unit 24 can be received by the relevant person of the parturient, midwife, doctor, etc. through the corresponding receiving device. It can also be reminded and assisted by midwives or doctors to perform VAS scoring.

It is understood that the above implementation manner merely illustrates an intelligent injection system according to an embodiment of the present invention, and the calculation module 22 is configured to perform the injection parameters mainly based on the size parameter of the uterine orifice and assisted by the pain level on the premise of selecting the intermittent injection mode, so as to implement automatic and refined pain relief administration and pain management according to the size and pain level of the uterine orifice obtained in real time during the delivery process of the parturient.
