Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an infrared vascular imaging system. Background Art

[0002] Venipuncture refers to inserting a relatively thin tube into a vein through the skin. Generally, the venipuncture method can be used to draw blood out of the body, and then various laboratory tests can be carried out, such as routine blood tests, or treatment for some patients who need long-term infusion. Venipuncture is an effective diagnostic and treatment method in clinical medicine.

[0003] Under traditional operations, puncture and injection completely rely on the experience of medical staff. By tying a tourniquet around the arm to make the blood vessels bulge, the position of the blood vessels is judged by finger tapping and direct visual inspection. For pediatric patients, this operation often causes the child's fear of injection. Moreover, the veins of children are thin, fragile, and deeply hidden, resulting in a low puncture success rate, which greatly increases the difficulty and tension of the work of medical staff. For elderly patients with diseases, their fragile and atrophied blood vessels also increase the difficulty of injection for medical staff.

[0004] To relieve the pain of children, avoid secondary or multiple punctures, reduce nurse-patient disputes, and improve the puncture success rate of medical staff, the prior art provides a vascular fluoroscopy technique. With the development of imaging technologies, such as near-infrared (NIR) light imaging and ultrasonic imaging, such imaging technologies can allow doctors or medical professionals to examine the subcutaneous tissues of patients, thereby increasing the efficiency of injection. Chinese Patent with Patent Publication No. CN112927199B discloses a method for selecting an injection point for non-intravenous injection treatment, including: S1, using a near-infrared imaging device to image the injection site of a user to obtain a near-infrared venous image ORIGINAL of the injection site; S2, performing preprocessing such as cropping and scaling on the near-infrared venous image ORIGINAL obtained in S1 to obtain a grayscale image GRAY; S3, performing grayscale normalization on the grayscale image GRAY obtained in S2 to obtain a normalized grayscale image NORM; S4, performing image binarization on the normalized grayscale image NORM obtained in S3 to obtain a near-infrared binary image BINARY; S5, performing filtering on the near-infrared binary image BINARY obtained in S4 to obtain a vascular binary image VESSEL; S6, collecting candidate pixel points from the vascular binary image VESSEL obtained in S5, respectively calculating the size of the range square of each candidate pixel point and comparing them to obtain the pixel point positions corresponding to one or more specific positions most suitable as injection points. This system performs pixel processing based on vascular fluoroscopy in order to obtain a clearer view for finding blood vessels. However, as Figure 1 shown, the vascular imaging device used in the prior art needs to be held by hand and requires two-person operation, which is inconvenient.

[0005] A Chinese patent with the patent publication number CN106075670A relates to a vein injection vascular fluoroscopy glasses, which includes a vein image imaging system. The vein image imaging system includes a near-infrared light camera, an imaging device, a digital image processor, and a pluggable power module. The vein injection vascular fluoroscopy glasses also include an adaptive glasses-type holding bracket and a monocular device box. The adaptive glasses-type holding bracket includes a projection lens and a planar lens. The monocular device box is movably connected in front of the projection lens of the adaptive glasses-type holding bracket. The near-infrared light camera is arranged at the front end of the monocular device box. The imaging device is arranged on the monocular device box corresponding to the projection lens, and displays the output image of the digital image processor on the projection lens.

[0006] Such devices are convenient to use during puncture injection, but before or during the use process, since it is necessary to understand the patient's physiological state, the viewing behavior of the inspection results related to the patient's physiological state will be affected. Specifically, medical staff need to view the patient's physiological state before observing the blood vessel image. In particular, the physical state of patients who need to use vascular fluoroscopy glasses for intravenous injection is relatively poor, and their physiological parameters have a relatively large impact on intravenous puncture, such as blood oxygen, blood pressure, etc. For example, when the patient's blood pressure is at the critical point, intravenous puncture cannot be performed on the patient to prevent the patient from having a hypertensive crisis.

[0007] Based on providing a detection report of the patient's physiological state for medical staff, so that medical staff can confirm whether the patient is in a puncturable state, the present invention provides an infrared blood vessel imaging system.

[0008] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, although the applicant studied a large number of documents and patents when making the present invention, all details and contents are not listed in detail due to space limitations. However, this does not mean that the present invention does not have the features of these prior arts. On the contrary, the present invention already has all the features of the prior arts, and the applicant reserves the right to add relevant prior arts in the background art. Summary of the Invention

[0009] For patients who need to be punctured, especially for inpatients who need to be punctured repeatedly, the current puncture method is that medical staff select a suitable time to provide injection to the patient according to experience, and the place where the injection behavior occurs is usually fixed. For example, the place is the patient's ward or a special injection room. Some hospitals will use infrared blood vessel imaging technology to facilitate medical staff to perform punctures. Before the puncture, for the patient's physiological condition, the hospital generally has a general case for reference.

[0010] Currently, for some patients, especially those who are hospitalized or need long-term injections, medical staff only inject patients according to experience or a pre-arranged process, but lack awareness of the physiological state of patients before injection. For example, some hypertensive patients or patients with cerebral blood supply diseases are prone to insufficient cerebral blood supply when undergoing puncture at inappropriate time points. In addition, for such patients, there are also differences in the results or effects of using infrared vascular imaging. Medical staff often change the mode or use parameters of the infrared vascular imaging device only after one or more irradiations in the standard mode do not obtain the expected results, resulting in a relatively large amount of time loss.

[0011] The present invention provides an infrared vascular imaging system, comprising: a detection module for collecting physiological parameters of a patient, an imaging module for providing an infrared image of the patient's blood vessels to medical staff, and a central server, wherein,

[0012] The central server receives at least one physiological parameter of the patient sent from the detection module;

[0013] In response to at least one physiological parameter of the patient sent by the central server, the imaging module changes its working mode or adjusts its working parameters when the patient undergoes puncture.

[0014] The detection module comprises a physiological detection unit, a first processing unit and a first transmission unit. The first processing unit is used for processing at least one physiological parameter to obtain at least one physiological parameter of the object. The first transmission unit is used for communicating with the central server.

[0015] When the collected physiological parameter is within a preset physiological parameter range, the first processing unit records the collected physiological parameter.

[0016] When the collected physiological parameter exceeds the preset physiological parameter range, the first processing unit communicates with the central server and transmits the collected physiological parameter.

[0017] According to a preferred embodiment, the physiological detection unit can collect data such as the patient's heart rate, blood oxygen, motion data and / or blood pressure. Preferably, the physiological detection unit can be a sensor for collecting data such as the patient's heart rate, blood oxygen, motion data and / or blood pressure.

[0018] Advantages of this technical solution:

[0019] Whether in a hospital environment or in a daily life environment, the behavior, emotions or movements of a patient can affect the patient's physiological parameters. This influence persists until the patient undergoes venipuncture, but the affected physiological parameters do not necessarily remain within a range that has a negative impact on the patient's body. During venipuncture, medical staff can only observe the patient's current status information and cannot understand the patient's physiological state before diagnosis and treatment. In particular, when there are potential problems with the patient's body, but the patient is in a resting state during venipuncture, these problems are difficult for medical staff to detect.

[0020] This technical solution can collect the physiological parameters of the patient when in a non-injection state, and based on a preset range, determine whether the patient's current physiological parameters are normal. At the same time, the detection module can send the selected abnormal physiological parameters to the central server.

[0021] On the one hand, this system can pre-detect the patient's status within a period of time before puncture, and use the real-time collected physiological data as a basis for medical staff to determine whether the patient's status is suitable for intravenous injection; on the other hand, compared with sending all the real-time collected data of the patient to the medical staff, this system can screen out the data that is valuable for medical staff to make a judgment (in particular, the amount of abnormal physiological data is generally less than that of normal physiological data, so the amount of data information that medical staff need to understand is greatly reduced), reducing the data processing volume of medical staff and increasing the work efficiency of medical staff.

[0022] According to a preferred embodiment, the imaging module includes a second transmission unit, an execution unit, and a second processing unit. The second transmission unit is used for communication with the central server. The second processing unit is used to process at least one physiological parameter obtained by communicating with the central server into an adjustment instruction for adjusting the working mode and / or working parameters of the imaging module. The execution unit changes the working mode and / or working parameters of the infrared blood vessel imaging unit based on the adjustment instruction.

[0023] According to a preferred embodiment, the imaging module includes a second transmission unit and an execution unit. The transmission unit is used for communication with the central server. The central server is used to process at least one physiological parameter obtained into an adjustment instruction for adjusting the working mode and / or working parameters of the imaging module, and send the adjustment instruction to the second transmission unit. The execution unit changes the working mode and / or working parameters of the infrared blood vessel imaging unit based on the adjustment instruction.

[0024] According to a preferred embodiment, when the physiological parameter that exceeds the preset physiological parameter range is lower than the lower limit of the preset physiological parameter range, the central server controls the imaging module to enter the third mode;

[0025] When the physiological parameter exceeding the preset physiological parameter range is higher than the upper limit of the preset physiological parameter range, the central server controls the imaging module to enter the first mode.

[0026] When the physiological parameter is within the preset physiological parameter range and the central server does not receive data parameters, the imaging module operates in the second mode.

[0027] According to a preferred embodiment, the detection module further includes a positioning detection unit for detecting the position information of the patient.

[0028] According to a preferred embodiment, based on the pre-divided regions, the first processing unit can divide the current position of the patient into an injection position and a non-injection position. The first processing unit receives the position information of the patient sent by the positioning detection unit and judges the position information of the patient. Preferably, the pre-divided regions include at least two positions, namely the injection position and the non-injection position, where

[0029] When the first processing unit determines that the patient is in the non-injection position based on the patient position information detected by the positioning detection unit, and at least one physiological parameter of the patient collected by the physiological detection unit does not conform to the first rule, the first transmission unit of the detection module communicates with the central server and transmits the collected physiological parameters, and no transmission is performed in other cases;

[0030] When the first processing unit determines that the patient is in the injection position based on the patient position information detected by the positioning detection unit, and at least one physiological parameter of the patient collected by the physiological detection unit does not conform to the second rule, the first transmission unit of the detection module communicates with the central server and transmits the collected physiological parameters,

[0031] wherein, the judgment criterion for the same physiological parameter of the first rule is higher than that of the second rule.

[0032] Preferably, the first rule and the second rule can be the specific values of the physiological parameters or the physiological states that can represent the direct influence of the physiological parameters. When the first rule and the second rule are numerical values, the above "higher than" does not only mean the numerical high or low, but refers to the high or low of the standard set for the physiological parameter when judging the normal state of the patient.

[0033] The injection position refers to the position where the patient can be punctured for injection (for example, ward, consulting room, etc.). The non-injection position refers to the position where the patient cannot be punctured for injection (for example, hospital corridor, hospital toilet, patient's residence, etc.).

[0034] Advantages of this technical solution:

[0035] 1. This technical solution does not require additional injection assistance equipment. By using existing equipment and the hospital information management system (HIS) established by the hospital, the above solution can be achieved, effectively reducing the cost of technology upgrade. In this technical solution, the central server can be the hospital information management system.

[0036] 2. This technical solution is based on the positioning detection unit and the physiological detection unit to clearly distinguish the physiological parameters of the patient in the injection area and the non-injection area. Therefore, it has advantages in saving data transmission flow and power loss of related equipment (such as acquisition equipment, which is usually a wearable intelligent device with limited battery life), and will not miss the pre-physiological information that can play an auxiliary reference role in the injection behavior, enabling the physiological conditions of the patient during the free activity period outside the injection area (usually outside the ward) to be selectively recorded, so as to screen out special situations such as inappropriate injection, thus providing a favorable guarantee for the working mode of the subsequent puncture infrared blood vessel imaging unit and reducing the risk of the patient being inappropriately punctured in special states.

[0037] 3. For the different states of the patient in different areas, this technical solution uses different detection criteria to judge whether the current state of the patient is abnormal. In particular, when the patient is in a non-injection position, since the environment or behavior experienced by the patient is richer than that in the injection position, the physiological state of the patient in the non-injection position is more likely to fluctuate. For example, the patient is mostly in a resting state in the ward and the consulting room, while when going to the toilet, the patient may walk quickly in the corridor, resulting in an increase in the fluctuations of blood pressure, blood oxygen or heart rate. Such an increase in fluctuations is very likely to exceed the set threshold (here refers to the threshold set based on the physiological parameters of the patient in the ward) due to the difference in the physical fitness of the patient, leading to false alarms of the system.

[0038] 4. This technical solution can intelligently weigh and switch based on the position change of the patient, improve the efficiency of data acquisition through a dynamic change process, and reduce the frequency of data transmission to the central server, thereby reducing the signal transmission noise impact on surrounding equipment.

[0039] For example, when the patient is outside, the patient's heart rate will be slightly higher than that in the resting state in the ward. When the patient returns to the ward or enters the injection room, the heart rate will drop. If the range of this change fluctuation is not large, the system can autonomously choose not to transmit data to prevent waste of battery life and signal transmission noise from affecting other equipment in the facility. However, if the patient's heart rate is too high when outside, it may affect the judgment or operation during subsequent injection. This sudden information may be provided to the doctor as a reliable reference basis. Therefore, this information needs to be transmitted to the host.

[0040] According to a preferred embodiment, the detection module can be a wearable intelligent device. Preferably, the wearable device is a bracelet, glasses, necklace or hood.

[0041] According to a preferred embodiment, the execution unit can be a device that differentiates blood vessels from the rest of the human body based on the principle that blood in blood vessels has specific absorption of red light.

[0042] According to a preferred embodiment, the positioning detection unit is a position sensor.

[0043] According to a preferred embodiment, the preset physiological parameter range is α to β. When the physiological parameter of the patient's physiological state is lower than α, between α and β, or higher than β, the imaging module generates different working mode selections and / or working parameter selections. For example, when the physiological parameter is higher than β, the imaging module enters the first working mode and prompts that the patient is not suitable for injection; when the physiological parameter is between α and β, the imaging module enters the second working mode; when the physiological parameter is lower than α, the imaging module enters the third working mode to detect unobvious blood vessels. Preferably, the imaging module changing its working mode or adjusting its working parameters means that based on the physiological parameters of the patient, the imaging module can at least change from the current working mode to one of the following three working modes: First mode: Stop imaging; Second mode: Image at the first power; Third mode: Image at the second power, where the first power is lower than the second power. Imaging at the first power means that imaging can be performed in the normal mode given by the device when the patient is in a normal state. The third mode means that the clarity of blood vessel imaging is improved by increasing the intensity of infrared supplementary light. For example, normal imaging is for a venous depth of 0 - 3 mm, while high-power imaging is for a venous depth of 3 - 6 mm.

[0044] Advantages of this technical solution:

[0045] This technical solution can pre-detect the physiological state of the patient for a period of time before puncture, and during puncture, by automatically switching the working mode or working parameters of infrared blood vessel imaging, it can automatically provide the most suitable working conditions for medical staff. When the patient is in a physiological state not suitable for puncture, it can timely warn the medical staff about patients who are not suitable for injection.

[0046] Furthermore, by refining the physiological state parameters of the patient, on the basis of determining that the patient is not suitable for puncture, the system can also distinguish the specific abnormal state of the patient (for example, hypertension or hypotension), thereby providing a judgment basis for generating different execution instructions for the central server.

[0047] This system sets a method for using an infrared blood vessel imaging system, including the following steps:

[0048] Detect at least one physiological parameter of a patient;

[0049] When the physiological parameter is lower than the lower limit of the preset physiological parameter range, display the infrared blood vessel image at the second power;

[0050] When the physiological parameter is within the preset range below the preset physiological parameter range, display the infrared blood vessel image at the first power;

[0051] When the physiological parameter is higher than the upper limit of the preset physiological parameter range, do not display the infrared blood vessel image, wherein the first power is lower than the second power.

[0052] This system sets an infrared blood vessel imaging method, which includes the following steps:

[0053] When the patient position information is in a non-injection position and at least one physiological parameter of the patient does not meet the first rule, the physiological parameter is sent to the central server;

[0054] When the first processing unit determines that the patient is in the injection position based on the patient position information detected by the positioning detection unit, and when at least one physiological parameter collected by the physiological detection unit does not meet the second rule, the first transmission unit of the detection module communicates with the central server and transmits the collected physiological parameter,

[0055] Wherein, the judgment criterion for the same physiological parameter of the first rule is higher than that of the second rule. Brief Description of the Drawings

Detailed Description of the Embodiment

[0060] The following is a detailed description with reference to the drawings.

[0061] In this application, "proximal" refers to the end close to the operator, and "distal" refers to the end far from the operator.

[0062] Embodiment 1

[0063] In the article "Analysis and Intervention of the Influence of Blood Pressure on Direct Arteriovenous Puncture", the relationship between blood pressure and the success rate of direct arteriovenous puncture was presented, and the following results were obtained based on the experimental results of measuring blood pressure before 1100 punctures on 103 patients: when the blood pressure was no more than 180 / 110 mmHg, the success rate of dorsalis pedis artery or radial artery puncture was 95.39%; when the blood pressure was greater than 180 / 110 mmHg, the success rate of puncture at the same site was 89.98%. The above results showed that the patient's blood pressure could directly affect the success rate of dorsalis pedis artery or radial artery puncture. Based on the clinical experimental results, it was proposed in this article that blood pressure should be measured before puncture. When the blood pressure was less than 180 / 110 mmHg, puncture could be carried out directly; when the blood pressure was equal to or greater than 180 / 110 mmHg, temporary catheterization could be performed, and a small dose of antihypertensive drug could be given according to the doctor's advice. When the blood pressure returned to about 160 / 90 mmHg, dorsalis pedis artery or radial artery puncture could be carried out again.

[0064] Clinical studies have found that low blood pressure can cause platelet aggregation and increased viscosity due to the slowdown of blood circulation, thus forming thrombus. When performing venous puncture, the behavior of the needle piercing the skin and blood vessels increases the probability of inducing thrombus in the injection tissue. At the same time, when patients need to be injected with some special drugs, such as dexamethasone and prednisone, medical staff need to first observe the patient's physical signs (whether the blood pressure is in a stable normal state). When the patient's blood pressure is controlled within the normal range, injection can be carried out for them. Otherwise, injecting such drugs will induce the patient's blood pressure to increase to the range of crisis symptoms.

[0065] Based on this, the present invention provides an infrared vascular imaging system that can provide medical staff with the judgment results of patient physiological parameters.

[0066] The detection module 100 includes a physiological detection unit 110, a first processing unit 130, and a first transmission unit 140. The first processing unit 130 is used to process the patient's blood pressure to obtain the blood pressure parameters of the object. The first transmission unit 140 is used to communicate with the central server 300.

[0067] When the collected blood pressure parameters are within the preset blood pressure parameter range, the first processing unit 130 records the collected blood pressure parameters;

[0068] When the collected physiological parameters exceed the preset blood pressure parameter range, the first processing unit 130 communicates with the central server 300 and transmits the collected blood pressure parameters, as Figure 1 shown.

[0069] Preferably, the blood pressure parameter range can be 160 / 90 mmHg to 180 / 110 mmHg.

[0070] According to a preferred embodiment, the blood pressure parameter range for confirming the physiological state of a patient can also be set with three blood pressure states including a first blood pressure state, a second blood pressure state, and a third blood pressure state. For the three blood pressure states, the imaging module 200 generates different working mode selections and / or working parameter selections. For example, in the third blood pressure state (hypertension), the imaging module 200 is in a non-working mode and prompts that the patient is not suitable for injection; in the second blood pressure state (normal blood pressure state), the imaging module 200 is in a normal working mode; in the first blood pressure state (hypotension), the imaging module 200 selects a high-power working mode to detect unobvious blood vessels. Preferably, the first blood pressure state is less than 160 / 90 mmHg. The second blood pressure state is within the range of 160 / 90 mmHg to 180 / 110 mmHg. The third blood pressure state is greater than 180 / 110 mmHg.

[0071] Embodiment 2

[0072] The present invention provides an infrared blood vessel imaging system capable of providing medical staff with the judgment results of a patient's physiological parameters.

[0073] The detection module 100 includes a physiological detection unit 110 for processing the blood pressure of a patient to obtain the blood pressure parameters of the object, a first processing unit 130, and a first transmission unit 140. The detection module 100 also includes a positioning detection unit 120 capable of obtaining the position information of the patient. The first transmission unit 140 is used for communicating with the central server 300. In this application, the first transmission unit 140 and the second transmission unit 210 can send information to the central server through wireless information transmission methods such as Bluetooth and WIFI.

[0074] In response to the patient being in the injection position collected by the positioning detection unit 120, the first processing unit 130 can make a judgment based on the detected blood pressure parameters, where

[0075] When the collected blood pressure parameters are within the preset first blood pressure parameter range, the first processing unit 130 records the collected blood pressure parameters;

[0076] When the collected physiological parameters exceed the preset first blood pressure parameter range, the first transmission unit 140 communicates with the central server 300 and transmits the collected blood pressure parameters.

[0077] The positioning detection unit 120 can detect the current position information of the patient and send it to the first processing unit 130. The first processing unit 130 can confirm the current area to which the patient belongs based on the map information it stores. Preferably, based on the division of the area, the position information of the patient is divided into an injection position and a non-injection position. Particularly preferably, the system can collect the area division for the patient's fixed puncture injection. For example, the map information of inpatients is set as the hospital map, and based on the historical information of puncture injections at two positions, the ward and the consultation room, the ward and the consultation room are set as the areas for determining that the patient is in the injection position, and other areas are set as the areas for determining that the patient is in the non-injection position.

[0078] In response to the patient being in the non-injection position collected by the positioning detection unit 120, the first processing unit 130 can process the collected blood pressure parameters using the second blood pressure parameter range.

[0079] When the collected blood pressure parameters are within the preset second blood pressure parameter range, the first processing unit 130 records the collected blood pressure parameters;

[0080] When the collected physiological parameters exceed the preset second blood pressure parameter range, the first transmission unit 140 communicates with the central server 300 and transmits the collected blood pressure parameters.

[0081] Preferably, the maximum value in the first blood pressure parameter range is less than the maximum value in the second blood pressure parameter range. Particularly preferably, the first blood pressure parameter range can be 160 / 90 mmHg to 180 / 110 mmHg. The second blood pressure parameter range can be 170 / 100 mmHg to 190 / 120 mmHg. Particularly preferably, the first blood pressure parameter range can be 150 / 90 mmHg to 170 / 100 mmHg. The second blood pressure parameter range can be 160 / 90 mmHg to 180 / 110 mmHg.

[0082] Embodiment 3

[0083] Based on the dynamic behavior areas of inpatients, the central server 300 divides the hospital into three areas, including an injection position area, a first non-injection position area, and a second non-injection position area.

[0084] The injection position area refers to the positions where the patient remains static, such as the ward and the injection room.

[0085] The first non-injection position area refers to the positions where the patient moves on a flat path, such as the corridor and the green space.

[0086] The second non-injection position area refers to the positions where the patient moves on a sloped path, such as the walking stairs and the green slope.

[0087] In this embodiment, the movement state of the patient is further divided into moving on flat ground and moving on a sloped ground. When moving on a sloped ground, the oxygen consumption and blood flow rate of the patient will increase compared to those when moving on flat ground. In this case, the increased oxygen consumption and blood flow rate of the patient are normal physiological states, rather than a problem that the patient cannot be injected. Nor is it necessary to send the data of the physiological parameters that have changed excessively due to the patient's excessive exercise to the medical staff to view and emphasize that there is a problem with the patient's physiological state. To avoid the above problems, the range for judging whether the physiological parameters of the patient meet the requirements in this system can change dynamically according to the different regions where the patient is located, thereby reducing the occurrence of the above problems.

[0088] According to a preferred embodiment, the range of physiological parameters for determining whether the patient is in a normal state in the injection position area is a to b. The range of physiological parameters for determining whether the patient is in a normal state in the first non-injection position area is a' to b'. The range of physiological parameters for determining whether the patient is in a normal state in the second non-injection position area is a'' to b''. Preferably, a ≥ a' ≥ a''. b ≤ b' ≤ b''.

[0089] According to a preferred embodiment, the physiological parameter is blood oxygen content. For example, the arterial oxygen saturation in the injection position area is 95% - 98%. The arterial oxygen saturation in the first non-injection position area is 94% - 98%. The arterial oxygen saturation in the second non-injection position area is 93% - 98%.

[0090] According to a preferred embodiment, when the positioning detection unit 120 collects that the patient is in the second non-injection position area, the first processing unit 130 can use the range of physiological parameters of arterial oxygen saturation of 93% - 98% to judge the collected physiological parameters.

[0091] When the collected arterial oxygen saturation of the patient is 93%, the first transmission unit 140 does not transmit this data to the central server 300, but this data can be recorded in the local memory database. When the collected arterial oxygen saturation of the patient is 91%, the first transmission unit 140 transmits this data to the central server 300. When the patient enters the injection state, on the one hand, the central server 300 can use the range of physiological parameters of arterial oxygen saturation of 95% - 98% as a rule for the arterial oxygen saturation collected based on the patient being in the injection position; on the other hand, the arterial oxygen saturation of 91% collected when the patient is in the second non-injection position area will also be provided by the central server 300 to the medical staff, providing a basis for the medical staff to judge whether there are potential hazards to the patient's body.
