[0040] The present invention proposes a monitoring system for the radial artery.

[0041] like Figures 1 to 4 A monitoring system for radial artery shown in the figure includes a controller, a communicator, a limiting mechanism 1, a connecting cable 2 and a hemostat 7, wherein the limiting mechanism 1 drives one end of the connecting cable 2, and the hemostat 7 is detachably connected to the other end of the connecting cable 2, and the hemostat 7 is used to be worn on the patient's wrist to stop bleeding in the radial artery; the limiting mechanism 1 is used to retract and release the connecting cable 2 and adjust the spacing distance between the limiting mechanism 1 and the hemostat 7; the hemostat 7 is provided with a signal transmitter; the communicator and the controller are both arranged on the limiting mechanism 1; the controller is electrically connected to the communicator, and the communicator signal is connected to the signal transmitter, and the controller is used to control the communicator to send a start signal to the signal transmitter when the connecting cable 2 and the hemostat 7 are disconnected, so that the signal transmitter sends a position signal to the outside world; the controller is also used to obtain the position signal through the communicator, and determine the spacing distance between the hemostat 7 and the limiting mechanism 1 according to the position signal obtained by the communicator, so that when the spacing distance is greater than or equal to the warning distance, an alarm message is sent to the outside world through the communicator.

[0042] The limiting mechanism 1 is fixed to one side of the bed, and the hemostat 7 is used to stop bleeding in the radial artery of the patient. The patient's activities are initially restricted through the connecting cable 2. When the patient needs to go to the toilet, the connecting cable 2 and the hemostat 7 are separated, and the patient's position is monitored in real time through the signal transmitter, which is convenient for medical staff to quickly find the patient and reduce safety risks.

[0043] Specifically, the limiting mechanism 1 is also provided with an audio module, which is electrically connected to the controller. The audio module is used to obtain audio information within a preset range around the limiting mechanism 1 and send it to the controller; the controller is used to store preset keywords and medical advice voice packages corresponding to each keyword; the controller is also used to determine text information based on the audio information, and determine whether there are keywords in the text information. When there are keywords in the text information, the corresponding medical advice voice package is determined according to the keywords, and the medical advice voice package is played through the audio module; when there are no keywords in the text information, the step of obtaining audio information within a preset range around the limiting mechanism 1 and sending it to the controller is executed. According to the sound information of the patient's surrounding conversation, timely medical advice reminders (i.e., medical advice voice packages) can further reduce the situation of patients not following medical advice. For example, the medical advice voice package corresponding to keywords such as jumping can be: Do not exercise excessively, and excessive exercise has the risk of bleeding. Patients can be prevented from exercising during radial artery hemostasis to avoid bleeding; and the medical advice voice package corresponding to keywords such as food names and water can be: Do not eat certain food and water, and surgery cannot be performed 24 hours after eating. Avoid patients who have to undergo other subsequent operations by mistake to ensure the normal progress of subsequent operations.

[0044] Specifically, the controller is also used to set a weight ranking for each keyword; the controller is also used to determine the number of keywords in the text information when there are keywords in the text information, and when the number of keywords in the text information is equal to one, execute the steps of determining the corresponding medical order voice package according to the keywords, and playing the medical order voice package through the audio module; when the number of keywords in the text information is greater than one, determine the keyword with the highest weight ranking according to each keyword and the weight ranking, and play the medical order voice package corresponding to the keyword with the highest weight ranking.

[0045] Specifically, the controller is also used to determine whether the number of keyword triggering times within a preset time period is greater than or equal to the warning number. When the number of keyword triggering times is greater than or equal to the warning number, the controller sends a warning message to the outside world.

[0046] Specifically, the hemostat 7 includes a middle key, a left key, a right key and a side sliding switch. The middle key is used to enter the control state; the left key and the right key are used to adjust the parameters of the hemostat 7 when it is pressed; the side sliding button is used to lock the middle key, the left key and the right key when the hemostat 7 is working to avoid accidental touch; when the hemostat 7 is in standby mode, the medical staff presses the left key and the right key at the same time, and the hemostat 7 is started to pressurize. When the left key and the right key are released, it stops. In this way, the hemostat 7 can be tied to the corresponding treatment part of the patient under the preset pressure. In the standby mode, the medical staff presses the left key for more than 3 seconds to start the automatic operation mode, and the real-time pressure flashes to prompt. When the pressure value reaches the set pressure value, the pressurization stops automatically. In the automatic operation mode, press the right key for more than 3 seconds to stop the automatic operation and release the pressure (release the pressure to normal pressure).

[0047] A connection connector 21 is provided on the side of the connection cable 2 away from the limiting mechanism 1 ; a connection mechanism 3 is provided on the outer wall of the hemostat 7 , and the connection mechanism 3 is used for detachably fixing the connection connector 21 so that the hemostat 7 and the connection cable 2 are fixedly connected.

The output end of the push-pull electromagnet 32 ​​is arranged opposite to the slot 33. A limiting through hole 22 is provided on the outer wall of the connection joint 21. The connection joint 21 is used to be inserted into the slot 33 so that the limiting through hole 22 is arranged opposite to the mounting through hole 34. The controller is electrically connected to the push-pull electromagnet 32. The controller is used to control the output end of the push-pull electromagnet 32 ​​to be inserted into the limiting through hole 22 when the limiting through hole 22 is opposite to the mounting through hole 34, so that the connection joint 21 is fixed in the slot 33. The push-pull electromagnet 32 ​​is inserted into the limiting through hole 22 to clamp the connection joint 21 in the slot 33, so as to realize the connection between the hemostat 7 and the connection cable 2.

[0052] The limiting structure 4 includes a first tension spring 41, a connecting column 42, a plug column 43 and a limiting plate 44. The limiting plate 44 is arranged at one end of the limiting plate 44 away from the push-pull electromagnet 32, and a connecting through hole is opened along the plate thickness of the limiting plate 44; one end of the connecting column 42 is connected to one end of the plug column 43, and the plug column 43 is located between the limiting plate 44 and the connecting column 42; the diameter of the connecting column 42 is larger than the diameter of the plug column 43; the first tension spring 41 is sleeved on the plug column 43, one end of the first tension spring 41 abuts the connecting column 42, and the other end of the first tension spring 41 abuts the limiting plate 44; the output end of the push-pull electromagnet 32 ​​is used to insert the end of the limiting through hole 22 away from the fixing hole 35, so that the output end of the push-pull electromagnet 32 ​​pushes the connecting column 42 and the plug column 43 in turn, and drives the plug column 43 to pass through the connecting through hole and insert into the fixing hole 35. The plug post 43 and the output end of the push-pull electromagnet 32 ​​form a linkage, and the stability of the connection between the hemostat 7 and the connecting cable 2 is further improved through multi-point limiting.

[0054] The connecting cable 2 includes a first cable 23, a second cable 24 and a detection mechanism 6, one end of the first cable 23 is connected to the detection mechanism 6, and the other end of the first cable 23 is detachably connected to the hemostat 7; one end of the second cable 24 is connected to the detection mechanism 6, and the other end of the second cable 24 is connected to the wire wheel 15; the controller is electrically connected to the detection mechanism 6, and the detection mechanism 6 is used to detect the tension data between the first cable 23 and the second cable 24 and send it to the controller; the controller is used to control the servo motor 14 according to the tension data, so that the servo motor 14 drives the wire wheel 15 to retract and release the connecting cable 2. The detection mechanism 6 detects the tension of the patient pulling the connecting cable 2 (i.e., the tension of pulling the first cable 23), and detects the tension of the servo motor 14 pulling the connecting cable 2 (i.e., the tension of pulling the second cable 24), so as to ensure that the connecting cable 2 is pulled out of the box body 11 to a suitable length to ensure the comfort of the patient; and to prevent the connecting cable 2 from being pulled out too long from the box body 11, which affects the use of the patient.

[0055] Specifically, the controller is used to determine whether the tension data is greater than a first preset tension value according to the tension data. When the tension data is greater than or equal to the first preset tension value, the servo motor 14 rotates forward to release the second cable 24 from the box body 11; when the tension data is less than the first preset tension value, it is determined whether the tension data is greater than or equal to zero. When the tension data is equal to zero, the servo motor 14 reverses to pull the second cable 24 into the box body 11; when the tension data is greater than zero, the servo motor 14 stops rotating and executes the step of determining whether the tension data is greater than the first preset tension value after a preset time period.
