Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and particularly relates to an infusion stand for internal medicine infusion. Background Art

[0002] An IV stand, also known as an IV stand or IV stand, is a medical device that supports an IV bag or bottle. It is mainly used for internal medicine infusion in hospitals to provide stable support and fixation for patients' IV infusion treatment.

[0003] However, in the current existing technology, ordinary infusion stands cannot heat the medicine solution, so infusion in cold seasons can easily cause cold hands and feet of patients, affecting the comfort of infusion; and most infusion stands cannot detect whether the medicine solution has been fully infused. If the nurse, patient or caregiver is not paying attention, problems such as blood backflow may occur, affecting the safety of infusion. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the prior art and to provide an infusion stand for internal medicine infusion.

[0005] In order to achieve the purpose of the innovative utility model, the following technical solutions can be used:

[0006] An infusion stand for internal medicine infusion comprises a vertically arranged rod body, a hook is arranged at the upper end of the rod body, a heating component is arranged on the rod body through a detachable structure, the bottom of the heating component abuts against a detection platform on the rod body, and a detection component is arranged on the detection platform for detecting whether the drug solution has been infused.

[0007] The infusion stand for internal medicine infusion of the present invention fully considers the comfort and safety of patients during the infusion process, wherein the rod body serves as the main structure of the infusion stand, and its vertical setting ensures that the infusion bottle or bag can be stably hung, and the hook is used to specifically hang the infusion bottle or bag, and the heating component can heat the medicine solution in a cold environment to avoid the patient feeling uncomfortable due to the infusion of low-temperature medicine solution, and it is installed and fixed by a detachable structure, which is convenient for cleaning, maintenance or replacement of the heating component, and it is also convenient to remove it when heating is not needed, saving space, and the detection table provides support for the heating component from below, ensuring that the heating component is stably fixed on the infusion stand, and at the same time, the detection table also provides a platform for the installation and setting of the detection component, and the detection component is used to monitor in real time whether the medicine solution has been infused, which is an important measure to ensure the safety of patients.

[0008] In the above-mentioned infusion stand for internal medicine infusion, the heating assembly includes a heating column with a C-shaped cross-section, a mounting groove is provided on the side wall of the heating column, a detachable structure is provided between the mounting groove and the rod body, and a vertically distributed spiral groove is also provided on the outer side wall of the heating column for embedding the infusion tube.

[0009] The heating component specifically heats through a heating column. An installation through groove is provided on the side of the heating column, making the cross-sectional shape C-shaped. The heating column can be snapped onto the rod body from the side through the installation through groove and cooperate with the detachable structure therein to form a flexible detachable fixation. The spiral card slot on the heating column is used to install the infusion tube, and the spiral trend increases the contact length with the infusion tube, ensuring the heating effect.

[0010] As an optimization, a heating component is provided inside the heating column. The heating component includes a heating agent or an electric heating wire or an electric heating film. The heating component can specifically convert electrical energy into heat energy through the electric heating wire or the electric heating film to achieve heating. Of course, a corresponding temperature control component is connected to the electric heating wire or the electric heating film to ensure the appropriate temperature. In addition, the heating component can also use the reaction heat release of the old-fashioned disposable medicine type to reduce the dependence on the supporting power connection facilities. The specific structure is prior art and will not be elaborated.

[0011] In the above-mentioned infusion rack for internal medicine infusion, the detachable structure includes a clamping column radially arranged on the side wall of the rod body. The clamping column is located above the detection table. The clamping column passes through the installation through groove and is radially limited. The detection table abuts against the bottom surface of the heating column.

[0012] There is a fit between the size of the clamping column and the size of the installation through groove, so that the clamping column cannot escape from the opening side of the installation through groove, ensuring the radial limit and realizing the installation of the heating column.

[0013] In the above-mentioned infusion rack for internal medicine infusion, the installation through groove includes a cylindrical section vertically penetrating the center of the heating column. The side wall of the cylindrical section is open outward through a radially opened relief opening. The width of the relief opening is adapted to the outer diameter of the rod body, but smaller than the inner diameter of the cylindrical section. The outer diameter of the clamping column is adapted to the inner diameter of the cylindrical section, but larger than the outer diameter of the rod body.

[0014] The inner side of the installation through groove is a cylindrical section, and the outer side is a rectangular relief opening that is open outward. The dimensional relationship among the relief opening, the rod body, the cylindrical section, and the clamping column realizes the detachable installation of the heating column on the rod body. Among them, the width of the relief opening allows the rod body to pass through, and the outer diameter of the clamping column allows the vertical sliding of the cylindrical section. During installation, the heating column can be laterally inserted above the clamping column. The relief opening passes through the rod body, and after insertion, it moves vertically downward. The cylindrical section just fits onto the clamping column until the bottom surface of the heating column abuts against the detection table. Since the outer diameter of the clamping column is larger than the relief opening, stable radial limit is thus achieved, that is, flexible disassembly and assembly are realized.

[0015] In the above-mentioned infusion stand for internal medicine infusion, at least one set of clamping structures is provided between the detection table and the heating column. The clamping structure includes an L-shaped clamping body and an L-shaped clamping groove respectively arranged on the top surface of the detection table and the bottom surface of the heating column. The clamping body and the clamping groove form vertical limit through rotational docking.

[0016] The clamping structure mainly realizes the limit through the docking of the L-shaped clamping body and the clamping groove. The L-shaped design allows the clamping body and the clamping groove to form vertical limit during the rotational docking process. This limiting effect effectively prevents the heating column from moving or falling off in the vertical direction. During installation, the operator only needs to place the heating component on the detection table and ensure that the L-shaped clamping body is aligned with the L-shaped clamping groove. Subsequently, by rotating the heating component, the clamping body gradually slides into the clamping groove until the two are completely docked. During this process, due to the special L-shaped design, the clamping body will automatically lock in the clamping groove, forming a stable connection, which is convenient and fast and has flexible detachable properties.

[0017] As an optimization, indicating markings are provided on the sides of the detection table and the heating column. When the clamping body and the clamping groove are docked, the indicating markings are exactly aligned, and the lower end of the spiral clamping groove is exactly docked with the positioning groove on the detection table.

[0018] The indicating markings provide an intuitive guide for the user to help with quick docking. When the indicating markings are exactly aligned, it means that the clamping body and the clamping groove have been correctly docked, ensuring the completion of the docking. In addition, the state after the docking of the clamping body and the clamping groove is also adapted to the positions of the lower end of the spiral clamping groove and the positioning groove, ensuring that after the docking is completed, the infusion tube can smoothly transition from the lower end of the spiral clamping groove to the positioning groove.

[0019] In the above-mentioned infusion stand for internal medicine infusion, the heating column abuts against the top surface of the detection table of the rod body. A positioning groove for clamping the infusion tube is provided on the side of the detection table. The upper end of the positioning groove is docked with the lower end of the spiral clamping groove. The detection component is provided between the positioning groove and the detection table.

[0020] The positioning groove is arranged on the side of the detection table for the infusion tube to be inserted, which can position the infusion tube at the lower end outlet of the spiral clamping groove, ensuring the stable winding of the infusion tube on the spiral clamping groove. In addition, the detection component is arranged at the positioning groove, and it can judge whether the liquid medicine is about to be finished by detecting the liquid condition in the infusion tube clamped in the groove.

[0021] As an optimization, the positioning groove vertically penetrates the detection table, including a circular section located inside and a guiding and limiting section located outside. The cross-section of the circular section is a circle adapted to the outer diameter of the infusion tube. The inner side of the guiding and limiting section is smoothly connected to the side wall of the circular section, and the outer side is open outward. The two side walls of the guiding and limiting section are arcs protruding in the middle, and the minimum distance is less than the outer diameter of the infusion tube.

[0022] The positioning groove is arranged vertically through to ensure the smooth vertical passage of the infusion tube. The circular section inside is mainly used to stably accommodate the infusion tube. The outer guide and limiting section is used to guide the insertion and removal of the infusion tube, and has a certain effect of limiting the infusion tube from falling out. This is specifically achieved through the arc-shaped side surface. The inner end of the side surface is smoothly connected to the circular section, and the outer end forms a structure similar to a fillet. The spacing in the middle part is small, which is used for limiting, ensuring that the insertion and removal are convenient, but has a certain limiting effect.

[0023] In the above-mentioned infusion stand for internal medicine infusion, the detection component includes a laser generator and an optical sensor arranged relatively to each other, and a detection mounting hole cross-connected with the positioning groove is horizontally penetrated on the detection platform, and the laser generator and the optical sensor are respectively arranged in the detection mounting holes on both sides of the infusion tube.

[0024] The detection component is specifically implemented through a laser generator and an optical sensor. This non-contact detection technology can effectively monitor the status of the infusion tube and ensure the normal progress of the infusion. The detection installation hole runs through the detection table to provide an installation position for the laser generator and the optical sensor. At the same time, the detection installation hole and the infusion tube intersect to ensure that the laser generator can accurately align with the infusion tube. When working, the laser generator emits a laser beam, which passes through the infusion tube and is projected onto the optical sensor on the opposite side. Since the refractive index of the laser is different when there is liquid medicine and no liquid medicine in the infusion tube, the intensity signal after the laser passes through will also change. The optical sensor detects the signal change to achieve the effect of judging the status of the infusion tube.

[0025] In the above-mentioned infusion stand for internal medicine infusion, the optical sensor is connected to the control end, which is used to detect the laser intensity passing through the infusion tube and send the data to the control end. The control end is connected to an alarm component; the alarm component includes an alarm light tube and / or an alarm sounder and / or an alarm vibrator.

[0026] The connection between the optical sensor and the control end enables the detected laser intensity data to be transmitted to the control end in real time for processing. The control end determines whether to trigger the alarm component according to the preset threshold or logic rule. The alarm component can be selected from the alarm lamp, alarm sounder and alarm vibrator, etc. After receiving the command from the control end, these components will immediately start and send out obvious warning signals to remind medical staff to pay attention to abnormal conditions during the infusion process. Furthermore, the control end can be connected to the relevant system of the nurse station to timely communicate the infusion status to the nurse station, thereby improving the safety of the infusion process. The specific structural principles and connection details of the laser generator, optical sensor, control section, alarm lamp, alarm sounder and alarm vibrator are common knowledge and will not be expanded in detail.

[0027] In the above-mentioned infusion stand for internal medicine infusion, a positioning piece is provided on the rod body. The positioning piece is located above the heating column and includes an annular connecting part and a strip-shaped positioning part. The annular connecting part is rotatably connected to the rod body. The strip-shaped positioning part extends radially, and a clamping interface is provided at the rotating end for clamping an infusion tube. The radial position of the clamping interface is adapted to the upper end of the spiral card slot, and the width of the strip-shaped positioning part is adapted to the width of the relief opening of the installation through slot.

[0028] The positioning piece is mainly used for positioning the infusion tube at the upper end of the spiral card slot to ensure that the infusion tube is stably wound around the heating column. Its annular connecting part is used to realize the rotational connection with the rod body. The strip-shaped positioning part extends radially, and a clamping interface is provided at the end for clamping the infusion tube. The rotatability of the positioning piece ensures that it can be rotated to exactly dock the clamping interface with the upper end of the spiral card slot, and the distance from the clamping interface to the rotation axis is adapted to the distance from the upper end of the spiral card slot to the axis, that is, the clamping interface is directly above the upper end of the spiral card slot. In this way, when the infusion tube is simultaneously clamped into the clamping interface and the spiral card slot, limited positions are formed in the axial and radial directions respectively, ensuring that the infusion tube is stably wound around the heating column. In addition, the width of the strip-shaped positioning part is less than or equal to the relief opening, ensuring the smooth loading and unloading of the heating column.

[0029] As an optimization, the strip-shaped positioning part includes an inner section and an outer section hinged together, and the hinge axis is located on the lower side. The outer section can be bent downward. When the heating component is not installed or upper positioning is not required, the outer section can be bent downward to avoid the scratching problem that may be caused by the lateral protrusion and make the whole more compact. When positioning is required, the bottom surface of the outer end rests on the heating column, without affecting the normal positioning effect.

[0030] In the above-mentioned infusion stand for internal medicine infusion, the hook includes a main body and a hook body provided on the outside of the main body. The main body is rotatably connected to the connecting column at the upper end of the rod body through a hook body mounting hole, and the bottom surface abuts against the limiting step at the upper end of the rod body. The upper end of the connecting column is threadedly engaged with an anti-loosening nut; a base is fixedly provided at the lower end of the rod body, and at least three groups of universal wheel assemblies are provided on the base.

[0031] The main body is rotatably connected to the upper end of the rod body, so that the hook can rotate freely within a certain range, facilitating medical staff to adjust the angle of the infusion bottle according to the position and needs of the patient. The bottom surface of the hook abuts against the limiting step, having a vertical limiting effect. The upper end of the connecting column is provided with an anti-loosening nut to prevent the hook from slipping out upward. Universal wheel assemblies are provided on the base, enabling the infusion stand to be easily moved on the ground, facilitating medical staff to transfer patients between different wards or treatment areas.

[0032] Compared with the prior art, the present utility model mainly has the following advantages:

[0033] 1. The heating component can heat the liquid medicine in a cold environment, avoiding discomfort for patients due to the infusion of low-temperature liquid medicine. It is installed and fixed through a detachable structure, which facilitates the cleaning, maintenance or replacement of the heating component. It is also convenient to remove it when heating is not required, saving space. The detection table provides support for the heating component from below, ensuring that the heating component is stably fixed on the infusion rack. At the same time, the detection table also provides a platform for the installation of the detection component, which is used to monitor in real time whether the liquid medicine has been transfused. This is an important measure to ensure patient safety.

[0034] 2. The inner side of the installation through groove is a cylindrical section, and the outer side is a rectangular relief opening, which is open outward. The dimensional relationship among the relief opening, the rod body, the cylindrical section and the clamping post realizes the detachable installation of the heating column on the rod body. Among them, the width of the relief opening allows the rod body to pass through, and the outer diameter of the clamping post allows the vertical sliding of the cylindrical section. During installation, the heating column can be laterally inserted above the clamping post, passed through the rod body through the relief opening, and then vertically moved downward after insertion. The cylindrical section just fits onto the clamping post until the bottom surface of the heating column abuts against the detection table. Since the outer diameter of the clamping post is larger than the relief opening, stable radial limitation is achieved, that is, flexible disassembly and assembly are realized.

[0035] 3. The clamping structure mainly realizes limitation through the docking of the L-shaped clamping body and the clamping groove, effectively preventing the heating column from moving or falling off in the vertical direction, and it is convenient and fast, with flexible disassembly.

[0036] 4. The positioning groove is arranged on the side of the detection table for the infusion tube to be inserted, which can position the infusion tube at the lower end outlet of the spiral card slot, ensuring the stable winding of the infusion tube on the spiral card slot.

[0037] 5. The detection component is specifically realized through a laser generator and an optical sensor. This non-contact detection technology can effectively monitor the state of the infusion tube, ensuring the normal progress of the infusion. The detection installation hole runs through the detection table, providing an installation position for the laser generator and the optical sensor. At the same time, the detection installation hole intersects with the infusion tube, ensuring that the laser generator can accurately align with the infusion tube.

[0038] 6. The positioning piece is mainly used for positioning the infusion tube at the upper end of the spiral card slot, ensuring that the infusion tube is stably wound around the heating column. Description of the Drawings

Specific embodiments

[0045] The following are specific embodiments of the present utility model and in conjunction with the accompanying drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0046] Specific embodiments are as Figures 1-5 shown. The infusion stand for internal medicine infusion of the present utility model includes a vertically arranged rod body 1. A hook 15 is provided at the upper end of the rod body 1. A heating component 2 is arranged on the rod body 1 through a detachable structure 3. The bottom of the heating component 2 abuts against a detection table 4 on the rod body 1. A detection component 5 for detecting whether the medicinal liquid has been transfused is provided on the detection table 4.

[0047] Specifically, the infusion stand for internal medicine infusion of the present utility model fully considers the comfort and safety of patients during the infusion process. Among them, the rod body 1 is the main structure of the infusion stand. Its vertical arrangement ensures that the infusion bottle or bag can be stably hung. The hook 15 is used to specifically hang the infusion bottle or bag. The heating component 2 can heat the medicinal liquid in a cold environment, avoiding discomfort for patients due to the infusion of low-temperature medicinal liquid. It is installed and fixed through the detachable structure 3, which facilitates the cleaning, maintenance or replacement of the heating component 2, and also facilitates removing it when heating is not required, saving space. The detection table 4 provides support for the heating component 2 from below, ensuring that the heating component 2 is stably fixed on the infusion stand. At the same time, the detection table 4 also provides a platform for the installation of the detection component 5. The detection component 5 is used to monitor in real time whether the medicinal liquid has been transfused, which is an important measure to ensure the safety of patients.

[0048] Such as Figure 2 、 3As shown in FIGS. 5, the heating assembly 2 includes a heating column 21 with a C-shaped cross-section. An electric heating wire is provided inside the heating column 21. An installation through groove 22 is provided on the side wall of the heating column 21. A detachable structure 3 is provided between the installation through groove 22 and the rod body 1. A vertically distributed spiral card slot 23 is further provided on the outer side wall of the heating column 21 for installing an infusion tube. The detachable structure 3 includes a clamping column 31 radially provided on the side wall of the rod body 1. The clamping column 31 is located above the detection table 4. The clamping column 31 passes through the installation through groove 22 and is radially limited. The detection table 4 abuts against the bottom surface of the heating column 21. The installation through groove 22 includes a cylindrical section 24 vertically penetrating the center of the heating column 21. The side wall of the cylindrical section 24 opens outward through a radially provided relief opening 25. The width of the relief opening 25 is adapted to the outer diameter of the rod body 1, but smaller than the inner diameter of the cylindrical section 24. The outer diameter of the clamping column 31 is adapted to the inner diameter of the cylindrical section 24, but larger than the outer diameter of the rod body 1.

[0049] Specifically, the heating assembly 2 is specifically heated by the heating column 21. The installation through groove 22 is provided on the side of the heating column 21, so that the cross-sectional shape is C-shaped. The heating column 21 can be snapped onto the rod body 1 from the side through the installation through groove 22 and cooperate with the detachable structure 3 therein to form a flexible detachable fixation. The spiral card slot 23 on the heating column 21 is used for installing the infusion tube. The spiral shape increases the contact length with the infusion tube and ensures the heating effect. The size of the clamping column 31 and the size of the installation through groove 22 are matched, so that the clamping column 31 cannot be disengaged from the opening side of the installation through groove 22, ensuring radial limitation and realizing the installation of the heating column 21. The inner side of the installation through groove 22 is a cylindrical section 24, and the outer side is a rectangular relief opening 25. The relief opening 25 opens outward. The dimensional relationship among the relief opening 25, the rod body 1, the cylindrical section 24 and the clamping column 31 realizes the detachable installation of the heating column 21 on the rod body 1. Among them, the width of the relief opening 25 allows the passage of the rod body 1, and the outer diameter of the clamping column 31 allows the vertical sliding of the cylindrical section 24. During installation, the heating column 21 can be laterally inserted above the clamping column 31. The relief opening 25 passes through the rod body 1 and vertically moves downward after being inserted. The cylindrical section 24 just slews onto the clamping column 31 until the bottom surface of the heating column 21 abuts against the detection table 4. Since the outer diameter of the clamping column 31 is larger than the relief opening 25, stable radial limitation is achieved, that is, flexible disassembly and assembly are realized.

[0050] As an optimization of this embodiment, a set of clamping structures 6 are provided between the detection table 4 and the heating column 21. The clamping structures 6 include L-shaped clamping bodies 61 and L-shaped clamping grooves 62 respectively provided on the top surface of the detection table 4 and the bottom surface of the heating column 21. The clamping body 61 and the clamping groove 62 form vertical limitation through rotational docking. Schematic marking lines are provided on the side surfaces of the detection table 4 and the heating column 21. When the clamping body 61 and the clamping groove 62 are docked, the schematic marking lines are exactly aligned, and the lower end of the spiral card slot 23 and the positioning slot 41 on the detection table 4 are exactly docked.

[0051] Specifically, the clamping structure 6 mainly realizes limiting by docking the L-shaped clamping body 61 and the clamping groove 62. The L-shaped design allows the clamping body 61 and the clamping groove 62 to form a vertical limit during the rotational docking process. This limiting effect effectively prevents the heating column 21 from moving or falling off in the vertical direction. During installation, the operator only needs to place the heating component 2 on the detection table 4 and ensure that the L-shaped clamping body 61 is aligned with the L-shaped clamping groove 62. Then, by rotating the heating component 2, the clamping body 61 gradually slides into the clamping groove 62 until the two are fully docked. During this process, due to the special L-shaped design, the clamping body 61 will automatically lock in the clamping groove 62 to form a stable connection. It is convenient and fast, and has flexible detachability. The schematic markings provide an intuitive guide for the user to help with quick docking. When the schematic markings are exactly aligned, it means that the card body 61 and the card groove 62 have been correctly docked, ensuring that the docking is completed. In addition, the docked state of the card body 61 and the card groove 62 is also adapted to the position of the lower end of the spiral slot 23 and the positioning slot 41, ensuring that after the docking is completed, the infusion tube can smoothly transition from the lower end of the spiral slot 23 to the positioning slot 41.

[0052] like Figure 1 , 2 As shown in Figures 3 and 4, the heating column 21 is in contact with the top surface of the detection platform 4 of the rod body 1. A positioning groove 41 for clamping the infusion tube is provided on the side of the detection platform 4. The upper end of the positioning groove 41 is butted with the lower end of the spiral clamping groove 23. A detection assembly 5 is provided between the positioning groove 41 and the detection platform 4. The positioning groove 41 vertically penetrates the detection platform 4, and includes a circular section 42 located on the inner side and a guide limit section 43 located on the outer side. The cross section of the circular section 42 is a circle adapted to the outer diameter of the infusion tube. The inner side of the guide limit section 43 is smoothly connected to the side wall of the circular section 42, and the outer side is open outward. The two side walls of the guide limit section 43 are arc-shaped with a convex middle, and the minimum spacing is smaller than the outer diameter of the infusion tube.

[0053] Specifically, the positioning groove 41 is arranged on the side of the detection table 4, and is used for the insertion of the infusion tube. The infusion tube can be positioned at the lower end outlet of the spiral groove 23, ensuring the stable winding of the infusion tube on the spiral groove 23. In addition, the detection component 5 is arranged at the positioning groove 41, and can judge whether the liquid medicine is about to be exhausted by detecting the liquid condition in the infusion tube connected to the groove. The positioning groove 41 is vertically penetrated, ensuring the smooth vertical passage of the infusion tube. The circular section 42 inside it is mainly used to stably accommodate the infusion tube, and the outer guide limit section 43 is used to guide the insertion and removal of the infusion tube, and has a certain effect of limiting the infusion tube from coming out, which is specifically realized by the arc-shaped side surface, the inner end of the side surface is smoothly connected to the circular section 42, and the outer end forms a structure similar to a fillet, and the spacing in the middle part is small, which is used for limiting, ensuring the convenience of clamping and removal, but has a certain limiting effect.

[0054] In this embodiment, the detection component 5 includes a laser generator 51 and an optical sensor 52 which are arranged opposite to each other. A detection installation hole 44 which is cross-connected with the positioning groove 41 is arranged transversely through the detection platform 4. The laser generator and the optical sensor 52 are respectively arranged in the detection installation holes 44 on both sides of the infusion tube. The optical sensor 52 is connected to the control end and is used to detect the intensity of the laser passing through the infusion tube and send the data to the control end. The control end is connected to an alarm component; the alarm component includes an alarm lamp and an alarm sounder.

[0055] Specifically, the detection component 5 is implemented by a laser generator 51 and an optical sensor 52. This non-contact detection technology can effectively monitor the state of the infusion tube and ensure the normal progress of the infusion. The detection installation hole 44 is set through the detection table 4, providing an installation position for the laser generator 51 and the optical sensor 52. At the same time, the detection installation hole 44 and the infusion tube intersect, ensuring that the laser generator 51 can accurately align with the infusion tube. When working, the laser generator 51 emits a laser beam, which passes through the infusion tube and is projected onto the optical sensor 52 on the opposite side. Since the refractive index of the laser is different when there is liquid medicine and no liquid medicine in the infusion tube, the intensity signal after the laser passes through will also change. The optical sensor 52 detects the signal change to achieve the effect of judging the state of the infusion tube. The connection between the optical sensor 52 and the control end enables the detected laser intensity data to be transmitted to the control end for processing in real time. The control end determines whether to trigger the alarm component based on a preset threshold or logic rule. The alarm component uses an alarm lamp and an alarm sounder. After receiving the command from the control end, these components will immediately start and send out an obvious warning signal to remind medical staff to pay attention to abnormal conditions during the infusion process. Furthermore, the control end can be connected to the relevant system of the nurse station to timely communicate the infusion status to the nurse station, thereby improving the safety of the infusion process.

[0056] As a further optimization, a positioning piece 11 is provided on the rod body 1, and the positioning piece 11 is located above the heating column 21, and includes an annular connecting portion 12 and a strip positioning portion 13. The annular connecting portion 12 is rotatably connected to the rod body 1, and the strip positioning portion 13 extends radially, and a card interface 14 is provided at the rotating end for clamping the infusion tube. The card interface 14 is adapted to the radial position of the upper end of the spiral card groove 23, and the width of the strip positioning portion 13 is adapted to the width of the makeshift opening 25 of the mounting through groove 22.

[0057] Specifically, the positioning piece 11 is mainly used for positioning the infusion tube at the upper end of the spiral groove 23 to ensure that the infusion tube is stably wound around the heating column 21. The annular connecting portion 12 is used to realize a rotational connection with the rod body 1. The strip positioning portion 13 extends radially, and a card interface 14 is provided at the end for clamping the infusion tube. The rotatability of the positioning piece 11 ensures that it can be rotated until the card interface 14 is just docked with the upper end of the spiral groove 23, and the distance between the card interface 14 and the rotation axis is consistent with the distance between the upper end of the spiral groove 23 and the axis, that is, the card interface 14 is located directly above the upper end of the spiral groove 23. In this way, when the infusion tube is simultaneously inserted into the card interface 14 and the spiral groove 23, limited positions are formed in the axial and radial directions respectively, ensuring that the infusion tube is stably wound around the heating column 21. In addition, the width of the strip positioning portion 13 is smaller than the clearance opening 25, ensuring smooth loading and unloading of the heating column 21.

[0058] In this embodiment, the hook 15 includes a main body and a hook body arranged on the outside of the main body. The main body is rotatably connected to the connecting column at the upper end of the rod body 1 through the hook body mounting hole, and the bottom surface is abutted against the limiting step at the upper end of the rod body 1. The upper end of the connecting column is threadedly engaged with an anti-slip nut 18; a base 16 is fixedly provided at the lower end of the rod body 1, and four sets of universal wheel assemblies 17 are provided on the base 16.

[0059] Specifically, the main body is rotatably connected to the upper end of the rod body 1, so that the hook 15 can rotate freely within a certain range, which is convenient for medical staff to adjust the angle of the infusion bottle according to the patient's position and needs. The bottom surface of the hook 15 abuts against the limiting step, which has a vertical limiting effect. The upper end of the connecting column is provided with an anti-drop nut 18 to prevent the hook 15 from falling out upward. The base 16 is provided with a universal wheel assembly 17, so that the infusion stand can be easily moved on the ground, which is convenient for medical staff to transfer patients between different wards or treatment areas.

[0060] Specific working principle: when installing the heating column 21, align its opening 25 with the rod body 1 above the clamping column 31, clamp it onto the rod body 1, and then slide downward, and the cylindrical section 24 is put on the clamping column 31 until the bottom surface and the detection table 4 are against each other, and rotate appropriately to make the clamping body 61 and the clamping groove 62 dock. When the infusion tube is wound from top to bottom, the positioning piece 11 is rotated to a suitable position, and the infusion tube is first clamped into the clamping interface 14, and then spirally wound on the spiral clamping groove 23, and clamped into the positioning groove 41 at the bottom, so that the infusion tube winding is completed, and the heating component 2 can be started to heat to a suitable temperature. When the liquid medicine is about to be infused, the liquid medicine in the infusion tube in the positioning groove 41 flows out, and the laser intensity detected by the optical sensor 52 suddenly changes. The signal is sent to the control end, and the control end triggers the alarm component to issue a corresponding alarm.
