Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a method, system, device and storage medium for rapid start-up of an infusion pump. Background Technology

[0002] Before injection, the internal mechanical gaps of the infusion pump must be eliminated to ensure proper injection. Current technology typically incorporates compressible pressure transmission contacts and pressure sensors. The elimination of momentum gaps is determined by checking whether these contacts and sensors are in contact—that is, whether the contact switch is closed. However, this method is overly simplistic. If the pressure sensor malfunctions and fails to send a closing signal, or if a single syringe repeatedly enters the rapid start-up phase, it could endanger the patient's life.

[0019] If the cumulative number of pulses is greater than the preset pulse value, the pusher is pushed to move along the direction of the pressure sensor at a second pulse speed, where the second pulse speed is less than the first pulse speed.

[0020] In one embodiment, determining whether the cumulative pulse count is greater than a preset pulse value includes:

[0021] If the cumulative number of pulses is less than or equal to the preset pulse value, then the pusher block continues to move along the direction of the pressure sensor at the first pulse speed.

[0023] If the cumulative number of pulses is greater than the preset pulse value, then the second pressure value of the pressure sensor is obtained, and it is determined whether the second pressure value is greater than the first pressure value;

[0024] If the second pressure value is less than or equal to the first pressure value, an abnormal alarm signal will be issued.

[0025] Secondly, this application provides a rapid start system for an infusion pump, comprising:

[0026] The acquisition module is used to acquire the startup information of the infusion pump and determine whether the infusion pump is being started for the first time based on the startup information.

[0048] Example 1

[0049] See Figure 1 , Figure 1 This embodiment provides a rapid start-up method for an infusion pump, applicable to various models of infusion pumps. The infusion pump includes a pressure sensor and a pusher block installed in the same pipeline. The method includes:

[0050] S101. Obtain the start-up information of the injection pump, and determine whether the injection pump is being started for the first time based on the start-up information.

[0051] After starting the infusion pump, if the conventional starting method is followed, the gap in the infusion pump's contact switch must be cleared before normal injection can proceed. Otherwise, if there is a gap in the contact switch, it may lead to unstable injection speed or even other safety accidents.

[0052] Traditional methods for eliminating gaps are slow. Typically, a pressure sensor is installed in the same tubing as the injector, with the injector and pressure sensor positioned at opposite ends of the tubing. When the injector is pushed and contacts the pressure sensor, it indicates that the gap in the contact switch has been eliminated. However, this process cannot be actively controlled, potentially wasting considerable time before normal injection can begin, resulting in a poor user experience. Therefore, this embodiment incorporates a fast-start mode to expedite the infusion pump's readiness for normal injection.

[0053] To determine whether the quick start mode needs to be activated, it is first necessary to determine whether the infusion pump meets the conditions for normal injection. If the conditions for normal injection are met, then injection can be performed directly without going through the quick start mode.

[0054] See Figure 2 Step S101 further includes:

[0055] S1011. Determine the initial startup parameters of the injection pump based on the startup information.

[0056] Upon receiving the start-up information from the syringe pump, the initial start-up parameters at the time of receiving the start-up information can be obtained.

[0057] S1012. Determine whether the initial startup parameters are preset startup parameters. If they are not preset startup parameters, determine that the injection pump is starting for the first time.

[0058] Specifically, the initial startup parameters can be the initial pressure of the pressure sensor when the injection pump receives the startup information, or other parameters of the injection pump. Since the injection pump can only inject normally after the gap between the plunger and the pressure sensor is eliminated, the initial startup parameters can determine whether the injection pump is starting for the first time. If it is not starting for the first time, the gap between the pressure sensor and the plunger has been eliminated. If it is starting for the first time, there will be a certain gap between the plunger and the pressure sensor, which will lead to a large difference in the pressure data collected by the pressure sensor in the two cases.

[0059] S102. If the injection pump is being started for the first time, then the fast start mode is activated and the first pressure value of the pressure sensor is obtained.

[0060] Specifically, if the injection pump is being started for the first time, the pusher is pushed along the direction of the pressure sensor according to the first pulse speed, and the pressure value of the pressure sensor is acquired in real time.

[0061] The initial pulse velocity, being faster than the normal injection velocity, quickly eliminates the gap between the plunger and the pressure sensor, allowing the injection pump to reach normal injection speed. To better control the plunger's movement speed, the pressure sensor's value needs to be acquired in real time. This allows for slowing down or stopping the plunger's movement as soon as it contacts the sensor, preventing over-push that could damage the injection pump or shorten the lifespan of components like the plunger.

[0062] S103. Determine whether the first pressure value is greater than a preset pressure value, wherein the preset pressure value is the pressure when the push block contacts the pressure sensor.

[0063] As the pusher moves continuously toward the pressure sensor under the control of the injection pump, the pressure value of the pressure sensor may change continuously. Therefore, it is necessary to determine in real time whether the first pressure value of the pressure sensor is greater than the preset pressure value. If it is less than the preset pressure value, it means that the pusher has not yet made contact with the pressure sensor and the pusher needs to be pushed to move in the direction of the pressure sensor.

[0064] S104. If the first pressure value is greater than the preset pressure value, calculate the cumulative number of pulses for the push block to move, and determine whether the cumulative number of pulses is greater than the preset pulse value.

[0065] If the first pressure value is greater than the preset pressure value, it means that the push block has made contact with the pressure sensor, and the gap between the push block and the pressure sensor has been eliminated.

[0066] In another scenario, if the pressure sensor is faulty, the pressure value of the infusion pump may exceed the preset pressure value upon startup, or the plunger may have moved for a period of time without contacting the pressure sensor, but the initial pressure value of the sensor has already exceeded the preset pressure value. If the quick start is immediately discontinued or normal injection is started directly, the infusion pump will have to push the plunger at the normal injection speed to eliminate the gap before injection can proceed. Since the normal injection speed is generally slow, this gap elimination process is lengthy, resulting in a prolonged inability to perform normal injection.

[0067] Therefore, after determining that the first pressure value is greater than the preset pressure value, it is also necessary to determine whether the cumulative number of pulses of the pusher is greater than the preset pulse value. The preset pulse value is related to the initial distance between the pusher of the injection pump and the pressure sensor. When the pusher moves to the preset pulse value, the pusher just moves to contact the pressure sensor.

[0068] The cumulative pulse count can be calculated by first obtaining the activation duration of the fast start mode, that is, starting the timer when the fast start mode is activated, and then calculating the cumulative pulse count based on the activation duration and the first pulse speed.

[0069] If the cumulative number of pulses is less than or equal to the preset pulse value, it means that the pusher block has not yet made contact with the pressure sensor. At this time, it is still necessary to continue to push the pusher block along the direction of the pressure sensor according to the first pulse speed.

[0070] S105. If the cumulative number of pulses is greater than the preset pulse value, then the fast start mode ends and normal injection begins.

[0071] If the cumulative number of pulses is greater than the preset pulse value, the pusher is pushed to move along the direction of the pressure sensor at a second pulse speed, where the second pulse speed is less than the first pulse speed.

[0072] See Figure 3 Step S105 further includes:

[0073] S1051. If the cumulative number of pulses is greater than the preset pulse value, then obtain the second pressure value of the pressure sensor and determine whether the second pressure value is greater than the first pressure value.

[0074] S1052. If the second pressure value is less than or equal to the first pressure value, an abnormal alarm signal is issued.

[0075] When the cumulative pulse count exceeds the preset pulse value, it indicates that the pusher has made contact with the pressure sensor. The second pressure value obtained at this time is usually greater than or equal to the preset pressure value. The first pressure value is the pressure value collected when the pusher is not in contact with the pressure sensor. If the second pressure value obtained at this time is less than or equal to the first pressure value, it indicates a malfunction in the pressure sensor or other problems. In this case, an abnormal alarm signal needs to be issued to remind medical personnel to repair the infusion pump or take other measures to avoid medical accidents.

[0079] The activation module 402 is used to activate the fast start mode and acquire the first pressure value of the pressure sensor if the injection pump is being started for the first time.

[0080] The judgment module 403 is used to determine whether the first pressure value is greater than a preset pressure value, wherein the preset pressure value is the pressure when the push block contacts the pressure sensor;

[0081] The calculation module 404 is used to calculate the cumulative number of pulses of the push block movement if the first pressure value is greater than the preset pressure value, and to determine whether the cumulative number of pulses is greater than the preset pulse value.

[0082] The injection module 405 is used to end the fast start mode and start normal injection if the cumulative number of pulses is greater than the preset pulse value.
