Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a method for detecting the in-situ filling of an infusion pump and an infusion pump. Background Technology

[0002] In the medical field, infusion pumps are commonly used devices for drug delivery. They precisely control the dosage and delivery rate of medications and are widely used in hospitals, clinics, and home care. While infusion pumps are designed primarily to provide more precise drug delivery, the installation of the syringe requires medical personnel to verify its correct placement. This not only increases the workload for medical staff but is also prone to human error. Incorrect syringe installation can lead to inaccurate drug delivery, or even drug leakage or other safety incidents, which can negatively impact patient treatment. Summary of the Invention

[0003] The main objective of this invention is to provide a method for detecting the in-situ filling of an infusion pump and an infusion pump, which aims to save medical staff's examination time and improve work efficiency.

[0004] To achieve the above objectives, the present invention proposes a method for detecting the in-situ filling of a syringe pump, the syringe pump having a pressure detection component for detecting the pressure applied to the syringe, the method comprising:

[0005] The syringe is installed into the injection pump to obtain the pressure change value of the pressure detection component;

[0006] Obtain the preset pressure change threshold;

[0007] When the pressure change value is less than the pressure change threshold, a prompt message is transmitted.

[0008] In one embodiment, the step of acquiring the pressure change information of the pressure detection component includes:

[0009] Obtain the initial pressure value A of the pressure detection component;

[0010] Obtain the first final pressure value B of the pressure detection component;

[0011] The pressure change information is obtained based on the difference between the first final pressure value B and the initial pressure value A.

[0012] In one embodiment, the step of determining the position information of the syringe based on the pressure change information of the pressure detection component includes:

[0013] Determine whether the pressure change information of the pressure detection component is within a preset pressure change range; if yes, the syringe is in the first position; if no, the syringe is in the second position.

[0014] In one embodiment, the step of obtaining the preset pressure variation range includes:

[0015] Obtain the initial pressure value A of the pressure detection component;

[0016] Obtain the second final pressure value C of the pressure detection component;

[0017] The preset pressure variation range is obtained based on the difference between the second final pressure value C and the initial pressure value A.

[0018] In one embodiment, the step of obtaining the second final pressure value C of the pressure detection component includes:

[0019] Obtain the second final sub-pressure values ​​C1, C2, C3...Cn of n pressure detection components;

[0020] The maximum value among the n second final sub-pressure values ​​is selected as the second final pressure value C.

[0021] In one embodiment, the step of obtaining the preset pressure variation range based on the difference between the second final pressure value C and the initial pressure value A includes:

[0022] The initial value of the preset pressure variation range is set;

[0023] The final value of the preset pressure variation range is calculated using the formula (CA)*1.5.

[0024] In one embodiment, the step of controlling the prompting module to output prompting information based on the position information of the syringe includes:

[0025] When the syringe is in the first position, a first prompt message is output.

[0026] In one embodiment, the step of controlling the prompting module to output prompting information based on the position information of the syringe includes:

[0027] When the syringe is in the second position, a second prompt message is output.

[0028] The present invention also proposes an injection pump for intravenous injection with a syringe having a raised rim, the injection pump comprising:

[0029] A pump body having a mounting groove for accommodating the syringe;

[0030] Along the pressure plate, the pressure plate is disposed on the pump body, and the pressure plate forms a limiting groove, the limiting groove being used to accommodate and limit the convex edge piece;

[0031] A pressure detection component is disposed on the inner wall of the mounting groove;

[0032] A rotating pressure handle is rotatably disposed on the pump body, and the rotating pressure handle is used to cooperate with the pump body to clamp the syringe;

[0033] A control module is located within the pump body, and both the pump body and the pressure detection assembly are electrically connected to the control module; and

[0034] A prompting module is electrically connected to the control module.

[0035] In one embodiment, a through hole is formed inside the mounting groove;

[0036] The pressure detection assembly includes a flexible waterproof layer, a transmission block, and a pressure sensor. The flexible waterproof layer covers the through hole. One end of the transmission block passes through the through hole into the mounting groove and abuts against the flexible waterproof layer. The pressure sensor is located on the pump body and abuts against the end of the transmission block away from the flexible waterproof layer. The pressure sensor is electrically connected to the control module.

[0037] In the technical solution of this invention, after the syringe pump is installed and clamps the syringe, it can obtain pressure change information from the pressure detection component. Then, the position information of the syringe can be determined through this pressure change information, and based on this position information, it can be determined whether the syringe is installed correctly. When the syringe is incorrectly installed, the prompting module can output corresponding prompt information to alert medical personnel, enabling them to take timely corrective measures and saving them examination time. Similarly, when the syringe is correctly installed, the prompting module can also output corresponding prompt information to alert medical personnel, facilitating their timely progress to the next step and improving work efficiency.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0055] This invention proposes a method for detecting the presence of syringe pump tubing.

[0056] Please see Figure 1 and Figure 6 In one embodiment of the present invention, the in-situ detection method for the syringe pump tubing provides a syringe pump 100, which includes a pump body 1, a pressure detection component 3, and a notification module 5; the pump body 1 has a mounting groove for accommodating a syringe 6, and the pressure detection component 3 is disposed in the mounting groove; the in-situ detection method for the syringe pump tubing includes:

[0057] Step S100: Obtain pressure change information of the pressure detection component 3;

[0058] Step S200: Determine the position information of the syringe 6 based on the pressure change information of the pressure detection component 3;

[0059] Step S300: Control the prompting module 5 to output prompting information based on the position information of the syringe 6.

[0060] It should be noted that the above steps are all implemented through a control module, which can be a microcontroller or a programmable logic controller, as long as it has control logic.

[0061] Understandably, since the pressure detection component 3 is located in the mounting slot, the pressure value detected by the pressure detection component 3 will change after the syringe 6 is placed into the receiving slot. The pressure change information will be different depending on the position of the syringe 6. Therefore, the installation position of the syringe 6 can be determined by this pressure change information, thereby determining whether the installation position of the syringe 6 is correct. After obtaining the installation position of the syringe 6, the prompting module 5 can be controlled to output the corresponding prompt information. This prompt information can be one or more of the following combinations: flashing indicator light, voice notification, and screen display notification, which can prompt medical staff.

[0062] In the technical solution of this invention, after the syringe pump 100 is installed with the syringe 6, it can obtain pressure change information from the pressure detection component 3. Then, the position information of the syringe 6 can be determined based on the pressure change information, and whether the syringe 6 is installed correctly can be determined. If the syringe 6 is incorrectly installed, the prompting module 5 can output corresponding prompt information to alert medical personnel, enabling them to take timely measures to adjust the installation and saving their examination time. Similarly, if the syringe 6 is correctly installed, the prompting module 5 can also output corresponding prompt information to alert medical personnel, facilitating their timely progress to the next step and improving work efficiency.

[0063] For details, please refer to Figure 2 In one embodiment of the present invention, the step of obtaining the pressure change information of the pressure detection component 3 includes:

[0064] Step S110: Obtain the initial pressure value A of the pressure detection component 3;

[0065] Step S120: Obtain the first final pressure value B of the pressure detection component 3;

[0066] Step S130: Obtain the pressure change information based on the difference between the first final pressure value B and the initial pressure value A.

[0067] It should be noted that the initial pressure value A of the pressure detection component 3 refers to the pressure value measured and recorded by the pressure detection component 3 before the syringe 6 is installed. This value represents the pressure reading of the syringe 6 mounting slot under no-load conditions. The first final pressure value B of the pressure detection component 3 refers to the pressure value measured and recorded again after the syringe 6 is installed in the mounting slot of the syringe pump 100. This value represents the pressure reading after the syringe 6 is installed. Finally, the pressure change information is obtained by calculating the difference between the first final pressure value B and the initial pressure value A. This difference can be expressed as ΔP1 = BA.

[0068] Specifically, in one embodiment of the present invention, please refer to... Figure 3The step of determining the position information of the syringe 6 based on the pressure change information of the pressure detection component 3 includes:

[0069] Step S210: Determine whether the pressure change information of the pressure detection component 3 is within the preset pressure change range;

[0070] Step S220: If the pressure change information of the pressure detection component 3 is within the preset pressure change range, then the syringe 6 is in the first position;

[0071] Step S230: If the pressure change information of the pressure detection component 3 is not within the preset pressure change range, then the syringe 6 is in the second position.

[0072] Understandably, if the syringe 6 is installed correctly, it will be tightly embedded in the mounting groove of the pump body 1. In this case, the pressure exerted by the syringe 6 on the pressure detection component 3 will be relatively high, resulting in a larger difference ΔP1 between the first final pressure value B and the initial pressure value A. Conversely, if the syringe 6 is installed incorrectly, there will be a gap between the syringe 6 and the inner wall of the mounting groove of the pump body 1. In this case, the pressure exerted by the syringe 6 on the pressure detection component 3 will be relatively low, resulting in a smaller difference ΔP1 between the first final pressure value B and the initial pressure value A. Based on this, a preset pressure variation range can be set. When ΔP1 is within this preset pressure variation range (i.e., ΔP1 is small), it can be determined that the syringe 6 is in the first position, i.e., the syringe 6 is in an incorrect installation position. When ΔP1 is outside this preset pressure variation range (i.e., ΔP1 is large), it can be determined that the syringe 6 is in the second position, i.e., the syringe 6 is in the correct installation position. By judging the relationship between ΔP1 and the preset pressure variation range, it is possible to determine whether the syringe 6 is correctly installed, thereby controlling the prompting module 5 to output the corresponding prompt information.

[0073] For details, please refer to Figure 4 In one embodiment of the present invention, the step of obtaining the preset pressure variation range includes:

[0074] Step S10: Obtain the initial pressure value A of the pressure detection component 3;

[0075] Step S20: Obtain the second final pressure value C of the pressure detection component 3;

[0076] Step S30: Obtain the preset pressure variation range based on the difference between the second final pressure value C and the initial pressure value A.

[0077] It should be noted that the initial pressure value A of the pressure detection component 3 refers to the pressure value measured and recorded before the syringe 6 is installed. This value represents the pressure reading of the syringe 6 mounting groove under no-load conditions. The second final pressure value C of the pressure detection component 3 is the pressure value measured and recorded under simulated incorrect installation, i.e., when the syringe 6 is in the first position. Simulated incorrect installation can be performed manually or by other means, including incorrect angles, positions, or using mismatched syringe 6 sizes. Understandably, if the syringe 6 is installed correctly, it will be tightly embedded in the mounting groove of the pump body 1, resulting in a higher pressure exerted by the syringe 6 on the pressure detection component 3, and consequently, a higher first final pressure value B and a higher second final pressure value C. Conversely, if the syringe 6 is installed incorrectly, there will be a gap between the syringe 6 and the inner wall of the pump body 1 mounting groove, resulting in a lower pressure exerted by the syringe 6 on the pressure detection component 3, and consequently, a closer first final pressure value B and a closer second final pressure value C. Based on this, a preset pressure variation range can be obtained by calculating the difference between the second final pressure value C and the initial pressure value A. This difference can be expressed as ΔP2 = CA. Using this method, a preset pressure variation range can be determined. When the pressure variation ΔP1 detected during actual use falls within this range, it can be determined that the syringe 6 is not installed correctly, and a corresponding prompt or alarm will be issued. This automated detection mechanism helps improve the safety and reliability of the syringe pump 100 and reduces potential risks caused by installation errors.

[0078] Furthermore, it is understandable that, due to the large number of assembly parts of the injection pump 100, the assembly and processing requirements for these parts are high. After assembly, the initial pressure value A of different injection pumps 100 may be different. Even if the initial pressure value A of different injection pumps 100 is the same, the position of their pressure detection components 3 may have slight differences, which will result in different first final pressure values ​​B after the syringe 6 is installed in the same way. Therefore, it is necessary to set a preset pressure variation range for each injection pump 100. This can effectively reduce the impact of the differences in assembly or parts of each prototype and improve the accuracy of identification.

[0079] To improve the ability to identify incorrect installation states, please refer to [link / reference]. Figure 5 In one embodiment of the present invention, the step of obtaining the second final pressure value C of the pressure detection component 3 includes:

[0080] Step S21: Obtain the second final sub-pressure values ​​C1, C2, C3...Cn of n pressure detection components 3;

[0081] Step S22: Select the maximum value among the n second final sub-pressure values ​​as the second final pressure value C.

[0082] It should be noted that the n second final sub-pressure values ​​C1, C2, C3...Cn are obtained by measuring and recording the pressure values ​​of the pressure detection component 3 under n simulated incorrect installation conditions. These n simulated incorrect installation conditions simulate different incorrect installation scenarios, including incorrect angles, positions, or the use of mismatched syringe 6 sizes. To ensure the accuracy of the results, the number of n is preferably greater than 5. The maximum value among the n second final sub-pressure values ​​represents the maximum pressure that can be measured under incorrect installation conditions. Using this maximum value as the second final pressure value C allows for a more conservative estimate of the pressure under incorrect installation conditions, thereby improving the ability of the syringe pump 100 to identify incorrect installation states. Simultaneously, this method also increases the robustness of the syringe pump 100 because it considers the maximum pressure variation that may occur under incorrect installation conditions.

[0083] For details, please refer to Figure 6 In one embodiment of the present invention, the step of obtaining the preset pressure variation range based on the difference between the second final pressure value C and the initial pressure value A includes:

[0084] Step S31: Set the initial value of the preset pressure variation range;

[0085] Step S32: Calculate the final value of the preset pressure variation range according to the formula (CA)*1.5.

[0086] It should be noted that the initial value of the pressure variation range is set directly, usually to 0. This initial value represents the starting point of the pressure variation range under ideal conditions or without the syringe 6 installed. It can also be set to smaller values ​​such as 3 or 5 depending on actual needs. The final value of the preset pressure variation range is calculated using the formula (CA) * 1.5, where C is the second final pressure value, A is the initial pressure value, and 1.5 is a safety factor to ensure sufficient margin to cope with possible pressure fluctuations. Common syringe 6 sizes are 2ml, 5ml, 10ml, 20ml, 30ml, and 50ml. Taking a 2ml syringe 6 as an example, if the syringe 6 is incorrectly installed, the initial pressure value A is 100, and the second final pressure value C is 150. Therefore, the final value of the preset pressure variation range is (150-100) * 1.5 = 75, meaning the preset pressure variation range is 0 to 75. This method ensures that the installation status of the syringe 6 is effectively monitored during the use of the syringe pump 100, thereby improving the safety and reliability of the syringe pump 100.

[0087] For details, please refer to Figure 3 In one embodiment of the present invention, the step of controlling the prompting module 5 to output prompting information based on the position information of the syringe 6 includes:

[0088] Step S310: When the syringe 6 is in the first position, output the first prompt message.

[0089] It is understandable that "syringe 6 in the first position" means that syringe 6 is in an incorrect installation position. The pressure change information of the corresponding pressure detection component 3 is within the preset pressure change range. The control module will activate the prompt module 5 and output the first prompt message. The first prompt message can be output through indicator lights, voice, or screen display to remind medical personnel that syringe 6 is in an incorrect installation position, allowing them to take timely measures to adjust it, saving their inspection time. Simultaneously, it restricts the injection operation of pump 1 to avoid accidents. The specific first prompt message can be a voice broadcast or text display of "Please install syringe 6 correctly" or other warning messages.

[0090] Further, please refer to Figure 3 In one embodiment of the present invention, the step of controlling the prompting module 5 to output prompting information based on the position information of the syringe 6 includes:

[0091] Step S320: When the syringe 6 is in the second position, output a second prompt message.

[0092] It is understandable that "syringe 6 in the second position" means that syringe 6 is in the correct installation position, and the pressure change information of the corresponding pressure detection component 3 is not within the preset pressure change range. The control module will activate the prompt module 5 and output a second prompt message. This second prompt message can be output through indicator lights, voice, or screen display to inform medical staff that syringe 6 is in the correct installation position, facilitating timely progress to the next step, such as selecting the brand of syringe 6, thus improving work efficiency. Specifically, the second prompt message can be delivered via voice broadcast or text display, such as "Please select the brand of syringe 6" or other prompts.

[0093] Please see Figure 7 , Figure 9 as well as Figure 10Based on the above-mentioned method for detecting the in-situ filling of the syringe pump, this invention also proposes a syringe pump 100. The syringe pump 100 is used for intravenous injection of a syringe 6. The syringe 6 has a protruding edge 61. The syringe pump 100 includes a pump body 1, a pressure plate 2, a pressure detection component 3, a rotating handle 4, a control module, and a prompting module 5. The pump body 1 has a mounting groove for accommodating the syringe 6. The pressure plate 2 is disposed on the pump body 1 and forms a limiting groove for accommodating and limiting the protruding edge 61. The pressure detection component 3 is disposed on the inner wall of the mounting groove. The rotating handle 4 is rotatably disposed on the pump body 1 and is used to cooperate with the pump body 1 to clamp the syringe 6. The control module is disposed on the pump body 1, and both the pump body 1 and the pressure detection component 3 are electrically connected to the control module. The prompting module 5 is electrically connected to the control module.

[0094] In the technical solution of this invention, after installing the syringe 6, the syringe 6 can be clamped and fixed by rotating the pressure handle 4. After installing and clamping the syringe 6, the control module can obtain the pressure change information of the pressure detection component 3; then, the position information of the syringe 6 can be determined through the pressure change information, and the installation position of the syringe 6 can be determined based on the position information of the syringe 6. When the syringe 6 is incorrectly installed, the prompting module 5 can output corresponding prompt information to remind medical staff, so that medical staff can take measures to adjust in time, saving medical staff's examination time; when the syringe 6 is correctly installed, the prompting module 5 can also output corresponding prompt information to remind medical staff, so that medical staff can proceed to the next step of work in time, improving work efficiency.

[0095] The prompt module 5 can output prompt information through indicator lights, voice or screen display, and the specific method is designed according to actual needs.

[0096] For details, please refer to Figure 8In one embodiment of the present invention, a through hole is formed inside the mounting groove; the pressure detection component 3 includes a flexible waterproof layer 31, a transmission block 32, and a pressure sensor 33. The flexible waterproof layer 31 covers the through hole, one end of the transmission block 32 passes through the through hole into the mounting groove and abuts against the flexible waterproof layer 31, and the pressure sensor 33 is located on the pump body 1. The pressure sensor 33 abuts against the end of the transmission block 32 away from the flexible waterproof layer 31, and the pressure sensor 33 is electrically connected to the control module. The flexible waterproof layer 31 can prevent residual medicine in the mounting groove from contacting the pressure sensor 33 through the through hole, ensuring the safe use of the pressure sensor 33. The flexible waterproof layer 31 can be made of silicone or rubber material. One end of the transmission block 32 passes through the through hole into the mounting groove and abuts against the flexible waterproof layer 31. Simultaneously, the pressure sensor 33 abuts against the end of the transmission block 32 furthest from the flexible waterproof layer 31. In this configuration, the pressure sensor 33 will have an initial value after installation. Since one end of the transmission block 32 enters the mounting groove, it will directly contact the flexible waterproof layer 31 after the syringe 6 is installed, causing the transmission block 32 to compress and deform the pressure sensor 33, thus obtaining timely and accurate pressure change information from the pressure detection component 3. Furthermore, to ensure the stability of the pressure sensor 33's installation and detection, the pressure sensor 33 is connected to the pump body 1 via screws.

[0097] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
