Infrared angiography glasses and detection module thereof

Abstract

In the detection module, when a first processing unit judges that a patient is in a non-injection position based on patient position information, a physiological parameter of the patient collected by a physiological detection unit does not conform to a first rule, and the first processing unit sends an infrared angiography signal to the first processing unit; the detection module transmits the collected physiological parameters to the central server; when the first processing unit judges that the patient is in the injection position based on the patient position information, the detection module transmits the collected physiological parameters to the central server under the condition that the physiological parameters, collected by the physiological detection unit, of the patient do not conform to a second rule, and the judgment standard of the first rule for the same physiological parameter is higher than that of the second rule; in response to the physiological parameters of the patient, the infrared angiography glasses change the working mode or adjust the working parameters when the patient is punctured. The working modes or working parameters of the infrared angiography glasses can be automatically switched, and the most suitable working conditions are automatically provided for medical staff.

Description

[0001] This application is a divisional application of application No. 202310634923.1, titled "Infrared blood vessel imaging system and use method thereof", filed on May 31, 2023. TECHNICAL FIELD

[0002] The present application relates to the technical field of medical devices, and particularly relates to an infrared blood vessel imaging glasses and a detection module thereof. BACKGROUND

[0003] Venipuncture refers to placing a relatively thin pipeline into a vein through the skin. Generally, blood can be introduced out of the body by using the venipuncture method, and then various tests can be performed, such as routine blood tests, or treatment for patients who need long-term infusion. Venipuncture is an effective diagnosis and treatment method in clinical treatment.

[0004] Under the traditional operation, the puncture injection completely relies on the experience of medical staff, the blood vessels are made to protrude by binding the arm with a tourniquet, and the position of the blood vessels is judged by finger palpation and direct visual observation. For young children, this operation often causes the children to be afraid of injection, and the veins of the children are small, fragile and hidden deep, so the success rate of puncture is low, which greatly increases the difficulty and tension of the work of the medical staff. For elderly patients with diseases, the fragile and atrophic blood vessels also increase the difficulty of injection for the medical staff.

[0005] To alleviate the suffering of sick children, avoid secondary or multiple puncture, reduce nurse-patient disputes, and improve the success rate of puncture by medical staff, the prior art provides a blood vessel perspective technology. With the development of imaging technology, such as near-infrared (NIR) light imaging and ultrasonic imaging, this type of imaging technology can allow doctors or medical professionals to examine the patient's subcutaneous tissue, thereby increasing the efficiency of needle injection. Patent No. CN112927199B discloses a method for selecting a non- intravenous injection treatment injection point, which comprises the following steps: S1, using a near-infrared imaging device to image the injection site of the user, obtaining a near-infrared vein image ORIGINAL of the injection site; S2, performing preprocessing such as cropping and scaling on the near-infrared vein image ORIGINAL obtained in S1 to obtain a grayscale image GRAY; S3, performing grayscale normalization processing on the grayscale image GRAY obtained in S2 to obtain a normalized grayscale image NORM; S4, performing image binarization operation on the normalized grayscale image NORM obtained in S3 to obtain a near-infrared binary image BINARY; S5, performing filtering operation on the near-infrared binary image BINARY obtained in S4 to obtain a blood vessel binary image VESSEL; S6, collecting candidate pixel points from the blood vessel binary image VESSEL obtained in S5, calculating the size of the range square of each candidate pixel point and comparing them to obtain the pixel point position corresponding to one or more specific positions that are most suitable as injection points. This system performs pixel processing based on blood vessel perspective to obtain a clearer field of view for finding blood vessels. However, as shown in Figure 1 , the blood vessel imaging device used in the prior art needs to be handheld and operated by two people, which is not convenient to operate.

[0006] Patent No. CN106075670A discloses a venous injection blood vessel perspective glasses, which comprises a venous image imaging system, the venous image imaging system comprises a near-infrared light camera, an imaging device, a digital image processor, a pluggable power module, the venous injection blood vessel perspective glasses further comprise an adaptive glasses type holding support and a monocular device box, the adaptive glasses type holding support comprises a projection lens and a plane lens, the monocular device box is movably connected in front of the projection lens of the adaptive glasses type holding support, the near-infrared light camera is arranged at the front end of the monocular device box, and 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.

[0007] Such devices are convenient to use when performing puncture injection, but before or during use, the viewing behavior of the examination results related to the physiological state of the patient is affected due to the need to understand the physiological state of the patient. Specifically, the medical staff needs to view the physiological state of the patient before observing the blood vessel image, especially the body state of the patient who needs to use the vascular perspective glasses for intravenous injection is relatively poor, and the physiological parameters of the patient have a greater impact on the venipuncture, such as blood oxygen, blood pressure, etc. For example, when the blood pressure of the patient is at a critical point, the patient cannot be punctured, and the patient is prevented from having a hypertensive crisis.

[0008] Based on providing the medical staff with a detection report of the physiological state of the patient, so that the medical staff can confirm whether the patient is in a puncturable state, the present application provides an infrared blood vessel imaging system.

[0009] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, a large number of literatures and patents have been studied by the applicant when making the present application, but due to the limitation of space, all the details and contents have not been listed in detail, but this does not mean that the present application does not have these characteristics of the prior art, on the contrary, the present application has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art in the background art. SUMMARY

[0010] For patients who need to be punctured, especially for patients who need to be punctured repeatedly in hospital, the current puncture method is that the medical staff provides injection to the patient at the appropriate time 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 use infrared blood vessel imaging technology to facilitate puncture by medical staff. Before puncture, the hospital generally has a general case for reference for the physiological condition of the patient.

[0011] At present, for some patients, especially for patients who need to be injected for a long time in hospital, the medical staff only injects the patient according to experience or pre-arranged procedures, but the physiological state of the patient before injection is not known, for example, some patients with high blood pressure or brain blood supply disease, if they receive puncture at an inappropriate time point, it is easy to cause insufficient blood supply to the brain, in addition, for such patients, the use of infrared blood vessel imaging also has differences in results or effects, and the medical staff often changes the mode or use parameters of the infrared blood vessel imaging device according to the inquiry or physical examination of the patient after failing to obtain the expected result after one or more standard mode irradiations, resulting in a large amount of time loss.

[0012] The present application provides an infrared blood vessel imaging system, comprising a detection module for collecting physiological parameters of a patient, an imaging module for providing an infrared image of blood vessels of the patient to medical staff, and a central server, wherein,

[0013] The central processor receives at least one physiological parameter of the patient sent by the detection module;

[0014] In response to at least one physiological parameter of the patient sent by the central processor, the imaging module changes its working mode or adjusts its working parameters when the patient receives puncture.

[0015] The detection module comprises a physiological detection unit, a first processing unit, and a first transmission unit. The first processing unit is configured to process at least one physiological parameter to obtain at least one physiological parameter of the subject. The first transmission unit is configured to communicate with the central server.

[0016] When the collected physiological parameter is within a preset physiological parameter range, the first processing unit records the collected physiological parameter.

[0017] When the collected physiological parameter is outside the preset physiological parameter range, the first processing unit communicates with the central server and transmits the collected physiological parameter.

[0018] According to a preferred embodiment, the physiological detection unit can collect data such as heart rate, blood oxygen, motion data, and / or blood pressure of the patient. Preferably, the physiological detection unit can be a sensor for collecting data such as heart rate, blood oxygen, motion data, and / or blood pressure of the patient.

[0019] The technical solution has the following beneficial effects:

[0020] Whether in a hospital environment or in a daily life environment, the behavior, emotion, or motion of a patient can affect the physiological parameters of the patient, and this effect can last until the patient receives intravenous puncture, but the affected physiological parameters may not necessarily remain within a range that has a negative impact on the patient's body. When intravenous puncture is performed, medical staff can only observe the current state information of the patient, and cannot understand the physiological state of the patient before diagnosis and treatment, especially when the patient has a hidden problem, but due to the patient being in a resting state when intravenous puncture is performed, such problems are difficult for medical staff to discover.

[0021] The technical solution can collect physiological parameters of a patient in a non-injection state, and determine whether the current physiological parameters of the patient are normal based on a preset range. Meanwhile, the detection module can send the screened abnormal physiological parameters to the central server.

[0022] On one hand, the system can detect the state of the patient in a time period before puncture, and provide the medical staff with the basis for judging whether the patient can be intravenously injected according to the real-time physiological data; on the other hand, compared with sending all the data of the patient to the medical staff, the system can filter out the data (especially, the amount of abnormal physiological data is generally less than that of normal physiological data, so the amount of data information that the medical staff needs to understand is greatly reduced) that is valuable for the medical staff to judge, thereby reducing the data processing amount of the medical staff and increasing the work efficiency of the medical staff.

[0023] According to a preferred embodiment, the imaging module comprises a second transmission unit, an execution unit and a second processing unit. The second transmission unit is configured to communicate with the central server. The second processing unit is configured to process the at least one physiological parameter obtained from the central server into an adjustment instruction for adjusting the working mode and / or the working parameter of the imaging module. The execution unit is configured to change the working mode and / or the working parameter of the infrared vascular imaging unit based on the adjustment instruction.

[0024] According to a preferred embodiment, the imaging module comprises a second transmission unit and an execution unit. The transmission unit is configured to communicate with the central server. The central server is configured to process the at least one physiological parameter obtained from the central server into an adjustment instruction for adjusting the working mode and / or the working parameter of the imaging module, and send the adjustment instruction to the second transmission unit. The execution unit is configured to change the working mode and / or the working parameter of the infrared vascular imaging unit based on the adjustment instruction.

[0025] According to a preferred embodiment, when the physiological parameter exceeding 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;

[0026] 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.

[0027] When the physiological parameter is within the preset physiological parameter range, the central server does not receive the data parameter, and the imaging module works in the second mode.

[0028] According to a preferred embodiment, the detection module further comprises a positioning detection unit configured to detect the position information of the patient.

[0029] According to a preferred embodiment, based on the pre-divided area, the first processing unit can divide the position where the current patient is located 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 area at least comprises two positions of the injection position and the non-injection position, wherein,

[0030] When the first processing unit determines that the patient is in the non-injection position based on the patient position information detected by the position detection unit, and the physiological detection unit collects at least one physiological parameter of the patient that does not meet the first rule, the first transmission unit of the detection module communicates with the central server and transmits the collected physiological parameter, and does not transmit in other cases;

[0031] When the first processing unit determines that the patient is in the injection position based on the patient position information detected by the position detection unit, and the physiological detection unit collects at least one physiological parameter of the patient that 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,

[0032] Among them, the judgment basis of the first rule for the same physiological parameter is higher than that of the second rule.

[0033] Preferably, the first rule and the second rule can be specific values of the physiological parameter or can represent the physiological state directly affected by the physiological parameter. When the first rule and the second rule are numerical values, the above-mentioned "higher" cannot only represent the high and low of the numerical value, but also refer to the high and low of the standard set for the physiological parameter when determining the normal state of the patient.

[0034] The injection position refers to a position (for example, a ward, a treatment room, etc.) where the patient can perform puncture injection. The non-injection position refers to a position (for example, a hospital corridor, a hospital toilet, a patient's residence, etc.) where the patient cannot perform puncture injection.

[0035] The beneficial effects of the technical solution are:

[0036] 1. The technical solution does not need to add additional injection auxiliary equipment, and can realize the above-mentioned scheme by using existing equipment and a hospital information management system (HIS) built by the hospital, thereby effectively reducing the cost of technical upgrading. In the technical solution, the central server can be a hospital information management system.

[0037] 2. The technical solution clearly distinguishes the physiological parameters of the patient in the injection area and the non-injection area based on the position detection unit and the physiological detection unit, thereby having advantages in saving data transmission flow and power consumption of related equipment (for example, collection equipment, which is usually a wearable smart device and has limited endurance), and not missing the pre-injection physiological information that can provide auxiliary reference for injection behavior. The physiological condition of the patient during the free activity period outside the injection area (usually outside the ward) can also be selectively recorded, so as to screen out special conditions such as unsuitable injection, thereby providing favorable guarantee for the working mode of the subsequent puncture infrared blood vessel imaging unit, and reducing the risk of unsuitable puncture of the patient in a special state.

[0038] 3. To address the different states of patients in different areas, this technical solution employs differentiated detection standards to determine whether the patient's current state is abnormal. In particular, when a patient is not at the injection site, the environment or behaviors they experience are more diverse than those they experience at the injection site. Therefore, the physiological state of patients in non-injection sites is more prone to fluctuations. For example, patients are mostly at rest in wards and consultation rooms, but when they need to go to the restroom, they may walk briskly in the corridor, causing increased fluctuations in their blood pressure, blood oxygen, or heart rate. Such increased fluctuations are very likely to exceed the set threshold (here referring to the threshold set based on the physiological parameters of patients in the ward) due to differences in patients' physical condition, leading to false alarms from the system.

[0039] 4. This technical solution can intelligently balance and switch based on changes in the patient's location, improve the efficiency of data acquisition through dynamic changes, and reduce the frequency of data transmission to the central server, thereby reducing the impact of signal transmission noise on surrounding equipment.

[0040] For example, when a patient is active outside, their heart rate may be slightly higher than when they are resting in their ward. When the patient returns to their ward or enters the injection room, their heart rate will decrease. If this fluctuation is small, the system can autonomously choose not to transmit data to prevent wasting battery life and to avoid transmission signal noise affecting other equipment in the facility. However, if the patient's heart rate is excessively high while active outside, it may affect judgment or operation during subsequent injections. This sudden change in heart rate may serve as a reliable reference for the doctor; therefore, it is necessary to transmit this information to the host computer.

[0041] According to a preferred embodiment, the detection module can be a wearable smart device. Preferably, the wearable device is a bracelet, glasses, necklace, or headgear.

[0042] According to a preferred embodiment, the execution unit is a device that distinguishes blood vessels from other parts of the human body by utilizing the principle that blood in blood vessels specifically absorbs red light.

[0043] According to a preferred embodiment, the positioning detection unit is a position sensor.

[0044] According to a preferred embodiment, the preset physiological parameter range is α~β. When the physiological parameter of the patient's physiological state is lower than α, between α~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 a first working mode and prompts the patient that it is not suitable for injection; when the physiological parameter is between α~β, the imaging module enters a second working mode; when the physiological parameter is lower than α, the imaging module enters a third working mode to detect non-obvious blood vessels. Preferably, the imaging module changes its working mode or adjusts its working parameters, which means that based on the physiological parameter of the patient, the imaging module can be at least changed from the current working mode to one of the following three working modes: first mode: stop imaging; second mode: image at first power; third mode: image at second power, wherein the first power is lower than the second power. Imaging at first power means that the patient can be imaged in the normal mode given by the device when the patient is in a normal state. The third mode means to increase the clarity of blood vessel imaging by increasing the intensity of infrared light compensation. For example, normal imaging is for a vein depth of 0~3mm, and high-power imaging is for a vein depth of 3~6mm.

[0045] The beneficial effects of the technical solution are:

[0046] The technical solution can detect the physiological state of the patient a certain period of time before puncture, and when performing puncture, it automatically switches the working mode or working parameter of the infrared blood vessel imaging to automatically provide the most suitable working conditions for medical personnel. When the patient is in a physiological state that is not suitable for puncture, the medical personnel can timely alert the medical personnel for the patient who is not suitable for injection.

[0047] Further, by refining the physiological state parameters of the patient, on the basis of judging that the patient is not suitable for puncture, the system can also distinguish the specific abnormal state of the patient (for example, high blood pressure or low blood pressure), thereby providing a basis for the central server to generate different execution instructions.

[0048] The system sets a use method of an infrared blood vessel imaging system, which comprises the following steps:

[0049] detecting at least one physiological parameter of the patient;

[0050] when the physiological parameter is lower than the lower limit of the preset physiological parameter range, displaying the infrared blood vessel image at the second power;

[0051] when the physiological parameter is lower than the preset physiological parameter range, displaying the infrared blood vessel image at the first power;

[0052] when the physiological parameter is higher than the upper limit of the preset physiological parameter range, not displaying the infrared blood vessel image, wherein the first power is lower than the second power.

[0053] The system sets an infrared blood vessel imaging method, comprising the following steps:

[0054] 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;

[0055] When the first processing unit determines that the patient is in an 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 meet the second rule, the first transmission unit of the detection module communicates with and transmits the collected physiological parameter to the central server.

[0056] Wherein, the judgment basis of the first rule for the same physiological parameter is higher than that of the second rule. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0061] The following will be described in detail in conjunction with the drawings.

[0062] In the present application, "proximal end" refers to the end close to the operator, and "distal end" refers to the end away from the operator.

[0063] Example 1

[0064] The article "Analysis and intervention of blood pressure on direct arterial-venous puncture" proposes the relationship between blood pressure and the success rate of direct arterial-venous puncture. Based on the experimental results of 103 patients before 1100 punctures, the following results are obtained: when the blood pressure is not greater than 180 / 110 mmHg, the success rate of dorsalis pedis artery or radial artery puncture is 95.39%; when the blood pressure is greater than 180 / 110 mmHg, the success rate of puncture at the same site is 89.98%. The above results show that the blood pressure of the patient can directly affect the success rate of dorsalis pedis artery or radial artery puncture. Based on the clinical experimental results, the article proposes that the blood pressure should be detected before puncture, and when the blood pressure is less than 180 / 110 mmHg, the puncture can be directly performed; when the blood pressure is equal to or greater than 180 / 110 mmHg, temporary catheterization can be performed, and a small dose of antihypertensive drug can be given according to the doctor's advice, and when the blood pressure returns to about 160 / 90 mmHg, the dorsalis pedis artery or radial artery puncture can be performed.

[0065] Clinical studies have found that low blood pressure can cause blood platelet aggregation and increased viscosity due to reduced blood circulation, thereby forming thrombus. When venous puncture is performed, the behavior of the needle piercing the skin and the blood vessel induces an increase in the probability of thrombus formation in the injection tissue. At the same time, when the patient needs to be injected with some special drugs, such as dexamethasone and prednisone, the medical staff need to first observe the patient's vital signs (whether the blood pressure is in a stable normal state), and when the patient's blood pressure is controlled within the normal range, the injection can be performed, otherwise the injection of such drugs can induce the patient's blood pressure to increase to the range of critical symptoms.

[0066] Based on this, the present application provides an infrared blood vessel imaging system capable of providing medical staff with the judgment result of the physiological parameters of the patient.

[0067] 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 blood pressure of the patient to obtain the blood pressure parameter of the object. The first transmission unit 140 is used to communicate with the central server 300.

[0068] When the collected blood pressure parameter is within the preset blood pressure parameter range, the first processing unit 130 records the collected blood pressure parameter;

[0069] When the collected physiological parameter exceeds the preset blood pressure parameter range, the first processing unit 130 communicates with the central server 300 and transmits the collected blood pressure parameter, as shown in Figure 1

[0070] Preferably, the blood pressure parameter range can be 160 / 90 mmHg-180 / 110 mmHg.

[0071] ​According to a preferred embodiment, the blood pressure parameter range for confirming the physiological state of the patient can further 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 (high blood pressure), the imaging module 200 is in a non-working mode and prompts the patient that the injection is not suitable; in the second blood pressure state (normal blood pressure state), the imaging module 200 is in a normal working mode; and in the first blood pressure state (low blood pressure), the imaging module 200 selects a high-power working mode to detect the blood vessels that are not obvious. 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-180 / 110 mmHg. The third blood pressure state is greater than 180 / 110 mmHg.

[0072] Embodiment 2

[0073] The present application provides an infrared vascular imaging system capable of providing a medical staff with a physiological parameter judgment result of a patient.

[0074] The detection module 100 includes a physiological detection unit 110 for processing the blood pressure of the patient to obtain the blood pressure parameter of the subject, a first processing unit 130 and a first transmission unit 140. The detection module 100 further includes a positioning detection unit 120 capable of obtaining the position information of the patient. The first transmission unit 140 is used for communication with the central server 300. In the present application, the first transmission unit 140 and the second transmission unit 210 can send information to the central server through wireless information transmission such as Bluetooth, WIFI, etc.

[0075] 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 parameter, wherein,

[0076] When the collected blood pressure parameter is within the preset first blood pressure parameter range, the first processing unit 130 records the collected blood pressure parameter.

[0077] When the collected physiological parameter exceeds the preset first blood pressure parameter range, the first transmission unit 140 communicates with the central server 300 and transmits the collected blood pressure parameter.

[0078] 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 belonging area of the patient based on the map information stored therein. Preferably, based on the division of the belonging area, the position information of the patient is divided into an injection position and a non-injection position. It is particularly preferable that the system can collect the position division area of the patient's fixed puncture injection. For example, the map information of the inpatient is set as the hospital map, and based on the historical information of the puncture injection performed by the patient in the two positions of the ward and the clinic, the ward and the clinic are set as the area for determining that the patient is in the injection position, and the other areas are set as the area for determining that the patient is in the non-injection position.

[0079] 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 parameter using the second blood pressure parameter range.

[0080] When the collected blood pressure parameter is in the preset second blood pressure parameter range, the first processing unit 130 records the collected blood pressure parameter;

[0081] When the collected physiological parameter exceeds the preset second blood pressure parameter range, the first transmission unit 140 communicates with and transmits the collected blood pressure parameter to the central server 300.

[0082] Preferably, the maximum value in the first blood pressure parameter range is less than the maximum value in the second blood pressure parameter range. It is particularly preferable that the first blood pressure parameter range can be 160 / 90 mmHg-180 / 110 mmHg. The second blood pressure parameter range can be 170 / 100 mmHg-190 / 120 mmHg. It is particularly preferable that the first blood pressure parameter range can be 150 / 90 mmHg-170 / 100 mmHg. The second blood pressure parameter range can be 160 / 90 mmHg-180 / 110 mmHg.

[0083] Embodiment 3

[0084] Based on the dynamic behavior area of the inpatient, 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.

[0085] The injection position area refers to a position where the patient remains static, such as a ward or an injection room.

[0086] The first non-injection position area refers to a position where the patient moves on a flat path, such as a corridor or a green space.

[0087] The second non-injection position area refers to a position where the patient moves on a path with a slope, such as a walking staircase or a green slope.

[0088] In the embodiment, the moving state of the patient is further divided into moving on flat ground and moving on sloping ground. When moving on sloping ground, the oxygen consumption and blood flow rate of the patient will be larger than those when moving on flat ground. In this case, the increased oxygen consumption and blood flow rate of the patient are normal physiological states, and there is no problem of the patient himself being unable to inject, and it is not necessary to send the data of the physiological parameters that change excessively due to excessive exercise of the patient to the medical staff to watch and emphasize that there is a problem with the physiological state of the patient. In order to avoid the occurrence of the above problems, the range for judging whether the physiological parameters of the patient are normal in the system can be dynamically changed according to different areas where the patient is located, thereby reducing the occurrence of the above problems.

[0089] According to a preferred embodiment, the physiological parameter range for judging whether the patient is in a normal state in the injection position area is a~b. The physiological parameter range for judging whether the patient is in a normal state in the first non-injection position area is a'~b'. The physiological parameter range for judging whether the patient is in a normal state in the second non-injection position area is a''~b''. Preferably, a≥a'≥a''. b≤b'≤b''.

[0090] According to a preferred embodiment, the physiological parameter is blood oxygen. 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%.

[0091] 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 physiological parameter range of arterial oxygen saturation 93%~98% to judge the collected physiological parameters.

[0092] 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, the central server 300 can collect the arterial oxygen saturation based on the patient being in the injection position with the physiological parameter range of arterial oxygen saturation 95%~98% on the one hand; on the other hand, the collected arterial oxygen saturation of the patient in the second non-injection position area is also 91%, which is provided to the medical staff by the central server 300, providing a basis for the medical staff to judge whether there is a hidden danger in the patient's body.
