Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a constant-speed, constant-temperature gastric tube injector. Background Technology

[0002] In clinical treatment, gastric tubes are often used for nasogastric feeding and gastrointestinal decompression. Liquid food, water, and medications are infused through the tube to enhance therapeutic efficacy. This is primarily for patients who cannot eat orally, especially those in a coma, with dysphagia, or in advanced stages of esophageal cancer who are unable to feed themselves.

[0003] Traditionally, infusion is mostly performed by medical staff holding a syringe, which is cumbersome, laborious, and requires frequent changes of fluids, resulting in many drawbacks. Currently, electric syringes have emerged, which use a motor to drive an internal plunger to move towards the end of the syringe, thereby expelling liquids, water, or medications from the syringe for infusion.

[0004] However, electric syringes still require medical staff to manually control the motor's rotation direction, speed, and other parameters, which is inconvenient to use. Therefore, there is a need for a gastric tube syringe that can automatically perform infusion and is easy for medical staff to operate. Summary of the Invention

[0005] This invention provides a constant-speed, constant-temperature gastric tube injector that can automatically perform infusion, making it convenient for medical personnel to operate.

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0007] The constant-speed, constant-temperature gastric tube injector includes an injector body, a propulsion module, a control module, and a heating module;

[0008] The control module is used to receive control information, including heating temperature, propulsion time, and single propulsion volume.

[0009] The control module is also used to calculate the propulsion distance and propulsion speed based on the propulsion time of a single propulsion volume, and control the operation of the propulsion module based on the propulsion distance and propulsion speed;

[0010] The heating module includes several annular heating wires and a temperature sensor disposed inside the syringe body; the annular heating wires are evenly wrapped around the outer wall of the syringe body along the axial direction of the syringe body.

[0011] The control module is used to acquire the actual temperature data collected by the temperature sensor, adjust the working temperature of the annular heating wire according to the actual temperature data and the heating temperature, calculate the current position of the liquid in the syringe body according to the advance distance and advance speed, filter out the annular heating wires that do not cover the liquid in the syringe body according to the pre-stored annular heating wire position information and the current position of the liquid in the syringe body, and mark them as invalid annular heating wires; the control module is also used to turn off invalid annular heating wires.

[0012] The basic principles and beneficial effects of the scheme are as follows:

[0013] When using this system, medical staff first input control information based on the patient's current injection needs. Then, the controller controls the push module and heating module to operate according to the control information. The heating module heats the liquid inside the syringe, and then the push module pushes the heated liquid out of the syringe, which is then introduced into the patient's body through a gastric tube.

[0014] This solution allows for the setting of infusion conditions according to actual needs, achieving automatic infusion with convenient operation. Furthermore, disabling the ineffective annular heating wire effectively saves energy and reduces variables affecting the syringe body temperature, improving control accuracy.

[0015] Furthermore, the syringe body has a liquid outlet at the bottom end, and a first one-way valve is fixed on the liquid outlet; the syringe body has an inlet on the outer wall near the bottom end, and a second one-way valve is fixed on the inlet.

[0016] Furthermore, the outer wall of the syringe body is also covered with a heat insulation layer.

[0017] It can keep you warm and prevent burns.

[0018] Furthermore, the control information also includes capacity;

[0019] The push module includes a push plate and a linear driver for controlling the movement of the push plate;

[0020] The control module is also used to calculate the suction distance based on the capacity, and control the linear actuator to reverse the action based on the suction distance, so that the push plate moves away from the liquid outlet.

[0021] By pushing the plate away from the outlet, a negative pressure is created, drawing liquid in from the inlet.

[0022] Furthermore, it also includes a communication module and a mobile terminal.

[0023] The communication module is used to obtain the current status information from the control module and send the status information to the mobile terminal; the status information includes actual temperature data, remaining propulsion time and remaining propulsion volume.

[0024] Medical staff can easily monitor the status of the syringe through a mobile device.

[0025] Furthermore, it also includes a notification module; the control module is also used to generate a reminder message after a single push is completed;

[0026] The notification module is also used to generate sound alerts based on the reminder information;

[0027] The communication module is also used to send reminder messages to mobile terminals.

[0028] It can remind medical staff that the current perfusion has been completed.

[0029] Furthermore, the notification module is also used to generate a work prompt sound when the push module is working.

[0030] You can inform people nearby that a grouting operation is currently underway.

[0031] Furthermore, it also includes a control panel and a pauser. The control panel is used to input control information and send the control information to the control module.

[0032] The pauser is connected to the control module via a data cable. The pauser is used to input a pause signal and send the pause signal to the control module. The control module is also used to control the drive module to stop working after receiving the pause signal.

[0033] Medical staff can input control information through the control panel, and the perfusion will proceed automatically. When medical staff need to leave briefly to handle other matters, they can hand the pause device to the patient. When the patient feels unwell, they can press the pause device to stop the perfusion and wait for medical staff to handle the situation, thus improving the safety of the perfusion.

[0034] Furthermore, the control panel is also used to input activation information and send the activation information to the control module. The control module is also used to receive the activation information and control the vibration of the pauser according to the remaining propulsion volume, and to receive the pause signal of the pauser; wherein, the more remaining propulsion volume, the greater the vibration intensity.

[0035] The communication module is also used to send activation information to the mobile terminal.

[0036] When medical staff need to leave briefly, they first enter the activation information through the control panel to activate the pauser. The patient can understand the perfusion progress by feeling the intensity of the pauser's vibration.

[0037] Furthermore, the mobile terminal is also used to determine whether to obtain activation information after obtaining status information. If activation information is not obtained, the mobile terminal is also used to collect motion data, calculate the user's number of steps based on the motion data, and determine whether the number of steps exceeds a threshold. If the threshold is exceeded, the mobile terminal is also used to determine whether to collect a work prompt tone. If no work prompt tone is collected, the mobile terminal sends activation information to the communication module. The communication module is also used to send the activation information to the control module.

[0038] By analyzing whether medical staff have moved and whether work prompts have been collected, it can be determined whether medical staff are near the syringe. If medical staff are not near the syringe and the pause device is not activated, the pause device will be automatically activated, allowing the patient to pause the infusion if discomfort occurs.

[0039] Figure 1 This is a logic block diagram of Embodiment 1 of a constant-speed, constant-temperature gastric tube injector;

[0040] Figure 2 This is a front view of Example 1 of the constant-speed, constant-temperature gastric tube injector. Detailed Implementation

[0041] The following detailed description illustrates the specific implementation method:

[0042] The markings in the accompanying drawings include: syringe body 1, outlet port 2, inlet port 3, linear actuator 4, control panel 5, pause device 6.

[0043] Example 1

[0044] like Figure 1 As shown, the constant-speed, constant-temperature gastric tube injector of this embodiment includes an injector body 1, a push module, a control module, a heating module, a notification module, a communication module, a mobile terminal, a control panel 5, and a pauser 6;

[0045] like Figure 2 As shown, the syringe body 1 has a liquid outlet 2 at its bottom end, and a first one-way valve is fixed to the liquid outlet 2; the syringe body 1 has an inlet 3 on its outer wall near the bottom end, and a second one-way valve is fixed to the inlet 3. The first one-way valve restricts liquid from flowing out but not in, and the second one-way valve restricts liquid from flowing in but not out. In this embodiment, the syringe body is connected to a nasogastric tube via the first one-way valve and to a liquid delivery tube via the second one-way valve. The delivered liquid includes liquid food, water, or medication.

[0046] The heating module includes several annular heating wires and a temperature sensor disposed inside the syringe body 1; the annular heating wires are uniformly wrapped around the outer wall of the syringe body 1 along the axial direction of the syringe body 1; the temperature sensor is fixed near the liquid outlet 2.

[0047] The outer wall of the syringe body 1 is also covered with a heat insulation layer; in other words, the annular heating wire is located between the heat insulation layer and the syringe body 1.

[0048] The push module includes a push plate and a linear actuator 4 for controlling the movement of the push plate; the push plate is located inside the syringe body 1, and the end of the push rod of the linear actuator 4 is fixedly connected to the push plate. The movement of the push plate inside the syringe body 1 is controlled by the extension and retraction of the push rod.

[0049] Control panel 5 is used to input control information and send it to the control module. The control information includes capacity, heating temperature, propulsion time, and single propulsion volume. For example, the heating temperature is 50-55 degrees Celsius, and the single propulsion volume is 50 ml.

[0050] In this embodiment, the control panel 5 is equipped with multiple input knobs, which are used to input control information such as heating temperature, propulsion time, and single propulsion volume.

[0051] The control module receives control information and calculates the propulsion distance and speed based on the propulsion time of a single propulsion volume. It then controls the propulsion module based on these distances and speeds. Since the inner diameter of the syringe body 1 is known, the area of ​​the inner circle is calculated from the inner diameter. Dividing the single propulsion volume by the inner circle area yields the propulsion distance. Finally, the propulsion time is calculated based on the propulsion time and distance.

[0052] The control module is also used to acquire the actual temperature data collected by the temperature sensor, adjust the working temperature of the annular heating wire according to the actual temperature data and the heating temperature, calculate the position of the liquid in the syringe body 1 according to the advance distance and advance speed, filter out the annular heating wires that do not cover the liquid in the syringe body 1 according to the pre-stored annular heating wire position information and the current position of the liquid in the syringe body 1, and mark them as invalid annular heating wires; the control module is also used to turn off invalid annular heating wires.

[0053] In this embodiment, each annular heating wire is controlled by an individual switch, which allows for the shutdown of inactive annular heating wires.

[0054] The control module is also used to calculate the suction distance based on the capacity, and control the linear actuator 4 to reverse the action based on the suction distance, so that the push plate moves away from the liquid outlet 2, and draws liquid from the liquid delivery pipe by generating negative pressure.

[0055] The communication module is used to acquire the current status information from the control module and send the status information to the mobile terminal. The status information includes actual temperature data, remaining propulsion time, and remaining propulsion volume. In this embodiment, the mobile terminal is a smartphone, and the communication module is a Bluetooth communication module connected to the smartphone via Bluetooth.

[0056] The notification module is used to generate a prompt sound when the push module is working.

[0057] The control module is also used to generate a reminder message after a single push; the notification module is also used to generate an audio reminder based on the reminder message; and the communication module is also used to send the reminder message to the mobile terminal.

[0058] The pauser 6 is connected to the control module via a data cable. In this embodiment, the pauser 6 includes a housing, a button fixed to the surface of the housing, and a vibration motor fixed inside the housing.

[0059] The control panel 5 is also used to input activation information and send the activation information to the control module. The control module is also used to control the vibration of the pauser 6 according to the remaining propulsion volume after receiving the activation information; the more remaining propulsion volume, the greater the vibration intensity. The communication module is also used to send the activation information to the mobile terminal.

[0060] The pauser 6 is used to input a pause signal and send the pause signal to the control module. The control module is also used to control the drive module to stop working after receiving the pause signal.

[0061] Example 2

[0062] The difference between this embodiment and Embodiment 1 is that, in this embodiment, the mobile terminal is further used to determine whether to obtain activation information after acquiring status information. If activation information is not acquired, the mobile terminal is further used to collect motion data, calculate the user's step count based on the motion data, and determine whether the step count exceeds a threshold. If it exceeds the threshold, the mobile terminal is further used to determine whether a working prompt tone is collected. If no working prompt tone is collected, the mobile terminal sends activation information to the communication module, which in turn sends the activation information to the control module. In this embodiment, the threshold is 20.

[0063] Example 3

[0064] The difference between this embodiment and embodiment two is that in this embodiment, the mobile terminal is also used to determine whether a connection is established with the communication module. If a connection is established, the mobile terminal collects the dialogue voice and records the duration of the dialogue voice that establishes the connection and drives the module to work.

[0065] If the mobile terminal fails to collect the work prompt tone, it will also determine whether the duration of the dialogue voice exceeds the preset time. If it exceeds the preset time, it will send an activation message to the communication module.

[0066] In this embodiment, the dialogue voice refers to the voices of the patient and medical staff. By determining whether the duration of the dialogue voice exceeds a preset time, the complexity of the patient's current condition can be indirectly characterized. For example, if the medical staff starts perfusion after a few questions (within the preset time), it indicates that the patient's condition is stable and the possibility of pausing during perfusion is low, so no activation message is sent. If the medical staff starts perfusion after a lot of questions (exceeding the preset time), the possibility of the patient's condition being complex is high, and the possibility of pausing during perfusion is also high, so an activation message needs to be sent.
