Description

Intraoperative volume and body temperature management instrument and method

Technical Field

The invention relates to surgical equipment, in particular to an intraoperative volume and body temperature management instrument and a method.

Background

The body temperature can be maintained in the normal range through autonomous regulation and behavior regulation, and the body temperature is maintained at 36.8-37.2 deg.C. However, in surgery hypothermia often occurs, i.e. a body temperature below 36 ℃.

The main reasons for intraoperative hypothermia are: firstly, peripheral blood vessels are expanded by anesthesia, and the loss of body temperature is accelerated; secondly, the anesthesia inhibits the body temperature regulating function of the body temperature regulating center, so that the body temperature regulating function of the body temperature regulating center is reduced or retarded, and the patient is difficult to keep normal temperature; the operation wound surface is directly opened, the protection effect of the skin barrier on the body temperature is lost, and the heat dissipation of wound surface tissues, particularly the thoracic cavity, the abdominal cavity and the like is accelerated; the large-flow carbon dioxide gas in the laparoscopic surgery is recycled, so that a large amount of heat energy is taken away; the temperature of the operation environment is usually low, so that the heat dissipation is quicker; sixthly, the heat of the patient is taken away by the liquid flushing; seventhly, the temperature of the surgical infusion liquid is always consistent with the ambient temperature, so that the body temperature of a patient is reduced; the operation disinfection and the local skin exposure also accelerate the body temperature emission of the patient.

Hypothermia is harmful to the body and is mainly characterized by: firstly, the low body temperature obviously increases the infection risk of the operation wound surface; hypothermia reduces the renal blood flow of the patient and even the renal function; hypothermia reduces cerebral blood supply of patients, and delirium possibility after operation is increased; the hypothermia causes the activity of various enzymes in the blood of a patient to be reduced, and the activity of thrombin is reduced to cause the bleeding to be increased; the activity of the drug metabolizing enzyme is reduced, so that the drug metabolizing time is changed, the metabolizing period is prolonged, and the revival becomes slow; lowering body temperature to lower the endocrine function of the patient; the hypothermia obviously increases the hospitalization period of the patients with various postoperative complications and prolongs the hospitalization period; lowering the body temperature to obviously increase the death rate of the patient after the operation; ninthly, hypothermia can cause chills, the patient experiences badly, the oxygen consumption is increased, and the probability of myocardial infarction is increased.

Body temperature has been considered by the medical community as an important vital sign, requiring that patient temperature must be monitored during surgery. At the present stage, all heat preservation measures are single, and the problem of maintaining the normal body temperature of a patient in the operation is difficult to really solve.

Meanwhile, infusion is the most common treatment means in the medical treatment process and is also an indispensable safety measure in the operation. The problems often faced in the intraoperative infusion are: firstly, children or patients with cardiopulmonary renal insufficiency need to be infused tightly, the infusion amount is strictly controlled, the infusion is calculated according to a formula, and the operation is difficult to measure and input; secondly, when the blood volume is insufficient, such as heavy bleeding and the like, rapid transfusion is needed, all rapid transfusion is finished manually or by pressurization at present, and the speed is not uniform and controllable, and accurate transfusion can not be carried out; thirdly, major surgery, messy transfusion in the surgery, frequent operation and easy confusion of transfusion quantity; fourthly, major operation, even if the total infusion amount is the same, the infusion is not mastered, the consequences are completely different, the messy input and output amounts are crossed, and doctors are difficult to control the optimal infusion time; major surgery, even if the total infusion amount is the same, the infusion types are different, and the consequence is also greatly different; sixthly, the input amount and the output amount are corresponding, the treatment modes in different time periods are matched with each other, otherwise, the treatment effect is different; the temperature of the liquid during transfusion is very important, otherwise, the low temperature of the patient is easily caused.

In conclusion, the body temperature management or the volume management is very important, and especially in a major operation, the operation effect of a patient is greatly influenced, and the prognosis and the recovery of the patient are influenced. The visual heat preservation and transfusion instrument is clinically and needs to be capable of observing the temperature of a plurality of places of a patient in real time, and ensuring the normal body temperature of the patient by combining a plurality of heat preservation means. The body temperature, the input amount and the output amount of the patient are visualized in a time-sharing manner, the body temperature and the volume state of the patient can be accurately and conveniently mastered, the optimal liquid is input or the optimal treatment measures are given at the optimal time, the operation safety of the patient is improved, and the rapid recovery of the patient is promoted.

In this embodiment, the infusion warming group is one of the parts of the warming group, and the infusion warming group includes a hanger 21, an initial warming mechanism 22, and a tube warming mechanism 11, wherein, as shown in fig. 1, the hanger 21 is telescopically arranged at the upper end of the box 1 by using a telescopic mechanism 20, and is used for suspending the liquid being input and storing the liquid waiting for infusion, the initial warming mechanism 22 is arranged below a hook of the hanger 21, and is used for supplying the liquid being input or/and the liquid waiting for infusion, the infusion bag has the longest time in this state, the initial warming mechanism 22 and the infusion bag have the longest warming time, and are arranged inside the box 1 than the tube warming mechanism 11, and are used for heating the infusion liquid on the infusion tube more effectively. Thus, heating the liquid on the infusion bag ensures that the initial temperature of the liquid is not too low, and is generally optimally set at 36-37 ℃. The initial heating mechanism 22 heats the infusion bag, can reduce the difference between the temperature of the infusion liquid and the target temperature, and then ensures that the temperature of the liquid infused into the human body is appropriate as much as possible by secondary heating of the infusion liquid on the infusion tube. The infusion device is most effective under the conditions of high infusion speed or low infusion liquid temperature. Of course, the initial heating means 22 and the tube heating means 11 may be used simultaneously, or the initial heating means 22 may be used alone, and may be determined according to the ambient temperature of the infusion solution and the temperature of the human body. Generally, the operation has less bleeding amount and slower transfusion speed, and the initial heating mechanism 22 can be selected only to meet the heat preservation requirement in the operation and avoid the use of the tube body heating mechanism 11. And when more bleeding occurs in the operation and the transfusion speed is higher or the transfusion amount is required to be larger, two necessary modes are adopted at the same time to ensure the heat preservation effect of the transfusion liquid.

In the above structure, as shown in fig. 2, the telescopic mechanism 20 includes a telescopic motor 201 (fixed at the lower end of one side of the box body 1), a sleeve 202, and a telescopic rod 203, when the telescopic motor 201 is started, the sleeve 202 can be driven to rotate, and the sleeve 202 drives the telescopic rod 203 to lift by using the internal thread, so as to drive the infusion bag to lift, and the height can be conveniently adjusted. Of course, a telescopic structure is not necessary, and the height of the hanger 21 can be adjusted by a simpler manual operation, which is not described herein.

As shown in fig. 3, which is a partially enlarged schematic view of fig. 2, an infusion weight sensor 214 is arranged on a hook of the hanger 21, the infusion weight sensor 214 is located above the initial heating mechanism 22, an infusion bag is hung on the infusion weight sensor 214, the infusion weight sensor 214 transmits the monitored gravity information to a data processor, and the data processor converts the gravity information into infusion speed information; the infusion weight sensor 214 is provided with an alarm to give an alarm when the infusion is finished.

Of course, the hanger 21 is provided with a sleeve 211 at the upper end thereof, the upper surface of the sleeve 211 is opened with a plurality of slits 212, and the horizontal hooks 213 are placed in the slits 212. When the liquid needs to be heated, the infusion bag is hung on the hook 215, and when the liquid does not need to be heated, the infusion bag can be hung on the transverse hook 213 or the hook 215, so that two usages are provided, and the usage is selected according to actual situations.

As shown in fig. 4 and 5, the initial warming mechanism 22 includes a warming chamber 220 and two warming plates 222, the warming chamber 220 may be hung on the hanger 21 (shown in fig. 2), may be provided inside the box 1, or may be provided at a position other than the present device, for warming the liquid to be used, for example, heating the washing liquid of the abdominal cavity, the pelvic cavity, or the thoracic cavity.

The two warming plates 222 can be moved closer to the bag or away from each other to release the bag; of course, the warming plate 222 is connected to a shaft sleeve 221, the shaft sleeve 221 is fixed to the top of the telescopic rod 203, and the shaft sleeve 211 can be fixed to the hanging bracket 203 and can rotate with the warming plate 222 through a pin. The heating plate 222 is connected to a motor or an air cylinder (not shown) for driving the heating plate to rotate.

The hanger 21 is further provided with an in-position sensor (not shown) for sensing whether the liquid bag is suspended between the two heating plates 222; when a liquid bag is induced to hang between the two heating plates 222, the heating plates 222 start heating; when no liquid bag is suspended between the two heating plates 222, the heating plates 222 stop heating; the in-place sensor can be set as a gravity sensor, when a liquid bag is hung between the two heating plates 222, the hanger 21 hook between the two heating plates 222 can sense that the gravity reaches a certain limit value or senses the change of the gravity, and starts heating to continuously heat the liquid in the infusion; when the hanger 21 hook between the two heating plates 222 can sense that the gravity can not reach a certain limit value or can not sense the change of the gravity, the transfusion is finished, and the heating is automatically stopped.

The warming bin 220 is provided with a sensor (not shown) for sensing whether the liquid bag is stored in the warming bin 220; when the liquid bag is sensed to be stored, the heating bin 220 starts to heat, so that the liquid in the heating bin is preheated, the temperature of the liquid is increased during infusion, and the heat preservation effect is realized on the body temperature; the liquid bag can not be sensed, no liquid exists in the heat preservation bin, and the heating bin 220 stops heating, so that the waste of heat energy is avoided. Similarly, the sensor of the warming bin 220 comprises a gravity sensor, and when the weight of the liquid in the warming bin reaches a certain limit value, the heating can be started; when the heating chamber is not up to a certain limit value, no liquid bag is stored in the heating chamber, and heating is not needed.

The heating plate 222 is provided with a heating wire (not shown) for heating the heating plate 222, and the heating plate 222 transmits the temperature to the liquid bag, i.e., the infusion bag. The temperature of the heating wire is controlled by a control system, and can be automatically controlled or manually input. The heating wire is provided with safe upper limit to the heating temperature of infusion bag, avoids not controlling, generally is not higher than 42 ℃, avoids causing the scald to the patient when directly using. Of course, the temperature may be relatively deviated, and the actual use temperature may be relatively low.

As shown in fig. 5, when the infusion bag is in place, the motor or the cylinder drives the two heating plates 222 to be combined close to the infusion bag, the middle arc of fig. 5 is the infusion bag, and then the heating wire starts to work to heat the infusion bag. After two warming plate 222 merge and are close to infusion bag, the heat can be better transmits for infusion bag, but need remind, if use gravity inductor response infusion speed on the gallows, two warming plate 222 need keep certain interval to infusion bag's the effect of being close to, avoid pressing from both sides tight infusion bag and cause the gravity-feed tank to respond to by the influence, lead to gravity-feed tank to respond to infusion speed inaccurate.

The device heats liquid in the infusion bag, and ensures that the initial temperature is not too low. In addition, the infusion bag to be used is heated in the heating bin 220 in advance, so that the heating time of the heating plate 222 is shortened, and the temperature is favorably and quickly increased.

As shown in fig. 6, the tube body heating mechanism 11 includes a heating box 111 and a tube body 112 disposed in the heating box 111, one end (inlet 113) of the tube body 112 is communicated with an infusion tube of an infusion bag, and the other end (outlet 114) is used for being communicated with a vein of a patient through a vein tube. A heater wire is provided in the heating chamber 111 to heat the pipe body 112, thereby heating the liquid inside the pipe body 112. The middle section of the tube body 112 can be made of a hard metal tube, and the two ends (the inlet 113 and the outlet 114) are made of soft medical tubes, so that the temperature of the liquid in the tube can be rapidly increased by utilizing the rapid heat-conducting property of the metal to reach the set target temperature. The metal used in the middle section of the tube 112 must meet medical requirements, and can be selected from metals such as aluminum, iron, copper, etc., and has low price and stable performance, and can achieve the best heating effect with the minimum cost.

When the infusion bag heating device is used in the specific embodiment, under the vast majority of road conditions, the amount of bleeding is small, the flushing amount is small, the infusion bag is heated only by initial heating, the heat insulation requirement in the operation of a patient can be met, the tube body heating mechanism 11 is not required to be used for heating the infusion pipeline, the use is convenient, the cost can be reduced, and the economic burden of the patient is relieved.

When the blood volume of a patient is insufficient or other factors cause the need of rapid transfusion, the liquid heating requirement after rapid replacement cannot be met by only depending on the two heating plates 222. When emergency blood transfusion is needed, the temperature of the blood product is lower, about 0-10 ℃, the retention time between the two heating plates 222 is short, and the extremely low temperature of the blood product cannot reach the temperature needed by the human body quickly only by heating through the tube body heating mechanism 11. Therefore, in large-scale operation, need rely on the initial heating of infusion bag and the pipeline of body heating mechanism 11 heats the cooperation and uses, utilize the initial heating of infusion bag to rise to being close human body temperature with the liquid temperature in the infusion bag, for example about 37 degrees centigrade, after let the pipeline of body heating mechanism 11 heat to higher temperature again, for example about 40 degrees centigrade, the collocation use of the two, can let liquid heat up fast, satisfy patient's temperature demand fast, be convenient for patient's body temperature and the control and the management of body fluid, reduce patient's operation risk on the one hand, on the other hand makes the patient heat visual, can effectively heat to the infusion, let the doctor grasp the state of an illness of patient more easily, thereby make the optimal processing scheme more easily, make patient's body temperature be in the optimum state. In specific operation, the temperature setting of the initial heating mechanism and the tube body heating mechanism 11 should be set according to the body temperature of the patient, when the body temperature of the patient is normal, the heating temperature should be set in a lower range, such as 37-38 ℃, when the body temperature of the patient is low, the heating temperature should be set to be slightly higher but below the upper safety limit, so as to avoid scalding, and the maximum temperature is preferably not more than 42 ℃.

In addition, can extend, when only using as a small amount of infusion of patient and using, this device can only use infusion bag initial heating, can satisfy the heat preservation demand, also can save the power consumption, saves expense, and it is also more convenient to use, reduces a lot of unnecessary operations.

The tubular body heating means 11 further comprises a lid 116, a port 117, as can be seen in fig. 10, the lid 116 covering the heating chamber 111, the port 117 being provided at the corner of the lid 116 for the provision of the inlet 113 and the outlet 114.

The infusion warming group is introduced to comprise a hanging bracket 21, an initial warming mechanism 22 and a tube warming mechanism 11, before use, a liquid bag to be used is placed in a warming bin 220 to be warmed in advance, when the infusion warming group is used, if the temperature of the liquid is too low or the body temperature of a patient is too low, a warming plate 222 is used for warming an infusion bag on the infusion bag, after an infusion tube of the infusion bag is connected to an inlet 113 of a tube 112, secondary heating is carried out in a warming box 111, so that the temperature of the liquid can be rapidly raised, the warming group is suitable for the temperature of a human body, and then the infusion bag is connected to the vein of the patient through a hose after passing through an outlet 114. If the temperature of the liquid is not low and the temperature difference with the body temperature of the patient is not large, the transfusion bag is heated by the heating plate 222 on the hanging bracket, and then the transfusion tube is directly connected to the vein of the patient without secondary heating. The two conditions are selected as required, so that the management of the infusion temperature and the management of the body temperature are realized, particularly, in some major operations, the body temperature of a patient is obviously reduced sometimes due to various reasons, at the moment, the initial heating cannot meet the requirement of the body temperature, and the body temperature of the patient is heated in a mode of combining the initial heating and the secondary heating.

The rinse warming group is another part of the warming group.

The position of the rinse-warming group (reference 3) can be seen in figure 1, and as shown in figure 8, the rinse-warming group comprises a carrier plate 301, a retraction mechanism; the bearing plate 301 is used for bearing the flushing water bag and the heating flushing water bag, and the bearing plate 301 can be accommodated on the outer wall of the box body 1 through the contraction mechanism. In addition, the bearing plate 301 is provided with an upper cover 309 (matched with a handle 310), so that firstly, heat preservation is realized, and secondly, the washing water is prevented from being polluted. The upper cover 309 has a small hole 311 on one side for extending the irrigation tube.

As shown in fig. 8, the retracting mechanism includes an upright 304, a rotating plate 303, a rotating rod 305, and a fixing rod 306, the upright 304 is fixed at the back of the box 1, the rotating plate 303 is fixed at the bottom of the supporting plate 301, the rotating plate 303 is embedded at the top end of the upright 304, one end of the rotating rod 305 is coupled to the middle of the upright 304, and the other end is coupled to the fixing rod 306, as shown in fig. 9, the rotating plate 303 is provided with a movable hole 307, a fixing groove 308 is provided at a position of the upper side wall of the movable hole 307 near the box 1, the fixing rod 306 is inserted into the movable hole 307, when the washing and heating set is needed, the supporting plate 301 is lifted upwards, so that the upright 304, the rotating plate 303, the rotating rod 305, and the fixing rod 306 are clamped in the fixing groove 308 under the coupling effect, the fixing rod 306 is clamped in the fixing groove 308, and the supporting plate 301 is released and fixed under the self weight. When the carrying plate 301 needs to be stored, the carrying plate 301 is lifted up, the fixing rod 306 is separated from the fixing groove 308, and then the carrying plate 301 is rotated downward, so that the carrying plate 301 is stored on the back of the box 1. The carrying plate 301 is further provided with a long shaft 302, the long shaft 302 is fixed on the back of the box body 1, and the carrying plate 301 rotates around the long shaft 302 when being stored.

For operations with larger irrigation volumes, such as: hysteroscopic surgery, ureteral kidney lithotripsy surgery, prostate electrocision, hysteroscopic surgery, salpingemphraxis, arthroscopic surgery, lung washing surgery and the like, and the body temperature loss in the surgery is mainly that a large amount of heat energy is carried away by flushing fluid in a body cavity, and the flushing fluid is preferably heated and kept warm under the condition. Among the above-mentioned hand speed, the flush fluid needs continuously to heat, continuously washes, and the sewage discharge of dyeing with blood, clear water gets into to guarantee the flush fluid circulation, make the camera in the body cavity visible to the surface of a wound, ensure the field of vision and wash. This kind of operation needs to use the flush fluid to wash in a large number, and a large amount of flush fluids are continuously washed the body intracavity, take away a large amount of body heats, want to implement the better heat preservation of effect, and the temperature of sparge water just will promote normal body intracavity temperature level in the art, or is higher than normal body intracavity temperature slightly, avoids body heat conduction to lead to the heat to lose for the flush fluid when washing, can also supply the heat for radiation heat dissipation simultaneously.

Of course, the flushing heating group and the transfusion heating group can be used independently or simultaneously.

The body surface warming group is another part of the warming group, is used for directly contacting the body surface to keep the temperature of the patient, and is mainly used for body temperature loss caused by surgical exposure. Mainly used in the operation that the transfusion volume is less in the art, and the flush fluid quantity is also less simultaneously, for example: surgery to open the pelvic cavity chest, exposure of the pelvic cavity chest, results in accelerated radiation heat dissipation. At the moment, one or more heat preservation measures can be taken simultaneously according to specific conditions, and the body temperature heat preservation effect in the operation is achieved together.

Referring to fig. 10, the body surface warming set 12 includes a body surface warming air pump 122, the body surface warming air pump 122 is connected to an air tube 123, the sidewall of the box body 1 is provided with air holes 121, the body surface warming air pump 122 sucks air from the air holes 121, and the air tube 123 blows the air to the body surface of the patient after warming to warm the body surface of the patient. When the operation radiation heat dissipation of a patient is fast, the patient with less infusion amount is far from enough to provide heat for the patient only by infusion heating, so if the body temperature of the patient is found to be reduced, the body surface of the patient needs to be heated while the infusion is heated. Especially in the open thoraco-abdominal pelvic surgery, the radiation heat dissipation is obvious, and the body temperature of the patient is very easy to reduce, so the body temperature of the patient needs to be maintained by means of the temperature rise of the body surface. Of course, the irrigating fluid is used during the operation, and the heated irrigating fluid is used as much as possible. For larger wound surfaces in operation, such as: the operation of opening abdomen, opening chest, large wound surface and much bleeding needs heat preservation in the operation of the patient, and can be used for heating the infusion support, heating the pipeline and preserving the heat by hot air, thereby ensuring that the patient does not lose the temperature.

The control of the body surface warming air pump 122 is also controlled by the data processor, and mainly controls the temperature of hot air and the volume of the hot air. The temperature can not be too high, so as to avoid scalding.

Thus, the heating group is introduced. Of course, the use of a warming group requires the cooperation of a pump group.

In the pump package, including transfer pump, flush pump, body surface heating air pump, introduce one by one below, in this embodiment, the transfer pump is infusion peristaltic pump 106, and the flush pump is flush peristaltic pump 107, and of course, the required water yield of sparge water is not big, but often needs quick washing, and the velocity of flow that needs is great, and the wash pipe way of use is also relatively thick, and consequently, the path liquid that wash peristaltic pump 107 is used for the body card to go into is thick a little.

Referring to fig. 6 and 7, the data processor includes an operation desk 10, the operation desk 10 is disposed at the upper end of the box body 1, an infusion peristaltic pump 106 and a flushing peristaltic pump 107 are disposed on the operation desk 10, and an infusion tube fixing member 108 and a flushing tube fixing member 109 are disposed at the fitting positions; after the infusion tube of the infusion heating group is clamped and fixed on the infusion tube fixing piece 108 and is matched with the infusion peristaltic pump 106, parameters can be set for the infusion peristaltic pump 106 through the operation table 10, and the background speed and the instant speed of infusion are adjusted; after the flushing pipe of the flushing and heating group is clamped and fixed in the flushing pipe fixing piece 109 and is matched with the flushing peristaltic pump 107, parameters can be set for the flushing peristaltic pump 107 through the operation table 10, and the background speed and the instant speed of flushing are adjusted.

Specifically, the infusion tube fixing member 108 and the irrigation tube fixing member 109 have substantially the same structure, and are preferably symmetrically arranged in pairs, and are respectively arranged at two ends of the peristaltic pump corresponding to the tube clamping portions, so as to avoid the tube from being folded and affecting the liquid flow. The number of the two is 3 in the present embodiment, taking transfusion as an example: the transfer line card of infusion bag is in first transfer line mounting 108, if the speed of infusing at this moment is slower, the temperature in the infusion bag is enough to satisfy the temperature that the patient needs, then from first transfer line mounting 108 back of coming out, transfer line lug connection to patient's vein passageway, if the infusion is faster this moment, the temperature in the infusion bag is not enough to satisfy the temperature that the patient needs, go into second transfer line mounting 108 behind the infusion peristaltic pump 106 with the transfer line card again, then be connected to the entry 113 of body 112 with the transfer line, entry 113 is the card in advance in third transfer line mounting 108, then pass through the transfer line with the export 114 of body 112 and be connected to the patient's vein.

The body surface heating air pump is mentioned above when the body surface heating set is introduced, and is not described in detail herein.

Patient temperature control is particularly important since body temperature is the fifth vital sign, and if not properly controlled, patients can develop a variety of complications. Especially, the body temperature is easy to reduce in major operations, and after the body temperature is low, the activity of various enzymes such as thrombin in the body of a patient is reduced, so that the speed of various biochemical reactions in the body is reduced, the blood coagulation function of the body of the patient is reduced, the drug metabolism is slowed down, the recovery is prolonged, various complications are increased, and even the life is threatened. In some operations, because the change of the state of illness often needs rapid transfusion, the temperature for heating the transfusion bag can not meet the temperature required by the patient, therefore, the invention heats the transfusion bag as the initial basis, and then heats the transfusion bag for the second time by utilizing the heating box 11 at the lower part, thereby ensuring that the temperature of the liquid entering the body of the patient is suitable for the temperature of the human body. Compared with the scheme of only heating the infusion tube used at present, the heating scheme provided by the invention can ensure that the temperature of the liquid is rapidly increased, the temperature required by a patient is rapidly met, the operation preparation time is shortened, and great convenience is brought to the operation.

The pump unit is now completely described. The pump package and the group of warming up need to combine the use, just can exert this device to the biggest effect, certainly, need select for use according to actual conditions.

The inductor is introduced here: the method comprises the following steps:

bleeding weight sensor: monitoring the dynamic change and the total amount of the bleeding volume and the weight of the patient;

drainage volume weight inductor: the dynamic change in the weight of the drainage volume and the total volume of the patient are monitored.

The sensor sends data to the data processor after monitoring the data, and the data processor processes the data to form data which is convenient for a doctor to master the state of an illness, such as: the total amount of the transfusion; infusion category component; the transfusion quantity in different time periods; the total amount of output; a quantity class component; discharging in different periods; thirdly, summarizing the output and input quantities in different time periods to obtain net input quantity or net output quantity and total amount; fourthly, the difference value of the flushing volume, the flushing fluid speed, the temperature and the flushing inlet and outlet volume of the patient; the body temperature and the transfusion temperature of the patient; sixthly, the total urine volume of the patient and the urine volume in different time; seventhly, the total amount of bleeding of the patient and the amount of bleeding in different time; eighthly, the total amount of the drainage volume of the patient and the time-sharing volume; ninthly, total blood transfusion amount of the patient and the distribution period of the blood transfusion time; statistical analysis of charge and volume of blood transfusion in the red (R), difference value of volume of blood transfusion and volume of blood transfusion; and so on.

Of course, the number of the inductors can be more than one, and other different types of inductors can be arranged.

The data processor is described below: in connection with the description of figure 6,

the data processor also comprises a liquid infusion type acquisition sensor arranged on the box body 1 or the hanging bracket 21, the liquid infusion type acquisition sensor comprises a camera input device, a voice input device or/and a keyboard input device, and is used for acquiring infusion liquid type information, and the sensor comprises one or more of the following components: infusion liquid category, infusion drug category and dose. When the sensor for acquiring the type of liquid infusion is arranged on the operation table 10 of the box body 1, the camera input device is indicated by reference numeral 103 in fig. 6, and the voice input device is indicated by reference numeral 104 in fig. 6. When the infusion apparatus is used, during infusion, information-containing marks such as bar codes or two-dimensional codes on infusion bags are scanned towards the camera input device 103, the data processor can receive information of the infusion bags, such as patient information, liquid types of the infusion bags, operation information and the like, of course, the voice input device 104 can be used for inputting information, the display screen 102 is a touch screen, the information can be modified, the input information can be prevented from being wrong, and the infusion apparatus can be used after confirmation. Of course, medication use times and dosages, events occurring during surgery, various important procedure start or end times, etc. may also be entered.

Further in connection with fig. 6, the console 10 comprises a display screen 102, a table top 101, which is placed thereon, and a number of buttons 105, such as confirmation, return, edit buttons, etc., are provided on the table top 101.

During infusion, the data processor monitors the weight change of the infusion bag in real time through the infusion weight sensor 214 at the infusion bag and feeds the weight change back to the data processor, the data processor converts the received weight information into an actual infusion speed, and the rotating speed of the infusion peristaltic pump 106 is adjusted according to the actual infusion speed, so that the infusion speed is closer to an infusion background speed and an instant speed which are input and set through the data processor. Of course, the infusion peristaltic pump 106 can also adjust the infusion speed according to the rotation speed of the infusion peristaltic pump, but the infusion speed should be verified with the infusion weight sensor 214 at the infusion bag, so that the problems that the error is difficult to correct after the infusion peristaltic pump is used for a long time, the error deviation is larger and larger, the maintenance reference is brought to manufacturers, the units of the instrument are subjected to subsequent service, and the accuracy is ensured.

That is to say, the data processor monitors the infusion speed through two positions, namely an actual infusion speed value a converted from the weight change of the infusion bag and an infusion speed value b converted from the rotating speed of the infusion peristaltic pump 106, and the data processor finally controls the infusion speed by combining the values a and b, wherein the control method comprises the following steps: if the actual speed value a of the infusion bag is too small, the rotating speed of the peristaltic pump is adjusted to be high, so that the infusion speed b at the peristaltic pump is increased, the speed at the infusion bag is indirectly increased, and the same is true on the contrary. In the operation, if the speed of the infusion bag is only controlled by the speed of the peristaltic pump, the reliability is low, and if the speed of the infusion bag is only controlled by the rotating speed of the peristaltic pump, the reliability is also low, so the invention integrates the control of the infusion bag and the speed of the peristaltic pump, one part is used for controlling the other part, and if one part has errors, the other part can be immediately adjusted, and the two parts are mutually verified and related. Meanwhile, the speed of the peristaltic pump is used as system control, namely data processor control, the speed of the infusion bag is used as a result of verifying parameters of the peristaltic pump, and if the speed of the infusion bag is higher, an alarm is given to remind of overhauling.

In addition, the infusion speed and the weight change of the infusion bag can calculate the input liquid amount, and of course, which time node is input, how much liquid is input, what kind of medicine is changed in which time node, and the like are known and are displayed on the display screen 102, so that the medical care observation is facilitated. Especially, in major operations such as liver-lung heart transplantation, doctors are busy in the operation and fully take into account of fatigue, and by using the instrument provided by the invention, the capacity, the body temperature and the medication state of a patient can be observed and known at any time, so that the condition of an illness can be treated conveniently in time, and the burden of the doctors is relieved.
