Description

Technical Field

[0001] This utility model relates to the field of medical technology, specifically to syringes. Background Technology

[0002] Extravasation of drugs is a common adverse reaction after intravenous infusion. It is caused by various reasons that lead to needle displacement during the infusion process, resulting in a reduced ability of the vein wall to repair trauma and a decreased ability to resist local inflammation caused by mechanical stimulation, chemical stimulation, and bacteria. This causes the drug to leak out of the blood vessel, which can easily lead to complications such as phlebitis and infection at the puncture site. In mild cases, it can cause local redness, swelling, and pain. In severe cases, it can lead to local skin tissue necrosis and even damage to nerves, muscles, and joints, causing tissue dysfunction.

[0003] Current methods for handling drug extravasation involve healthcare professionals injecting a local sealing solution using a syringe to seal the extravasated drug. During injection, once the area around the needle is filled with the solution, the needle angle needs to be adjusted to maintain the seal. However, this process requires highly experienced healthcare professionals to accurately locate the extent of extravasation and the correct needle insertion point, increasing the strain on healthcare resources and limiting the effectiveness of the injection procedure. Utility Model Content

[0004] In view of this, the present invention provides a syringe to solve the problem that existing injections of local sealing solutions can only be performed by medical personnel with sufficient experience, which increases the pressure on medical resources and leads to limitations in injection operation.

[0005] This utility model provides a syringe, comprising:

[0006] Needle shell;

[0007] An injection needle is disposed at one end of the needle housing near the skin to be injected. The injection needle has a first state in which it is disposed inside the needle housing and a second state in which it extends outside the needle housing.

[0008] A drive unit, connected to the needle housing, is used to drive the needle housing to rotate in at least two directions;

[0009] A detection unit is disposed on the needle housing, and the detection unit is used to form a subcutaneous image when the injection needle is in the first state.

[0010] Beneficial effects: By incorporating a detection unit, the extent of drug extravasation under the skin can be monitored in real time, allowing less experienced medical staff to accurately locate the injection site for the local sealing solution based on the extent of extravasation. During the injection, the medical staff can adjust the position of the injection needle via the drive unit, enabling real-time adjustment of the injection angle and surrounding the extravasated drug with the local sealing solution. Therefore, local sealing solution injections can be performed by less experienced medical staff, thereby reducing the pressure on medical resources.

[0011] In one optional implementation, the detection unit includes:

[0012] The probe structure is located at the end of the needle shell near the skin;

[0013] The display structure is connected to the probe structure.

[0014] Beneficial effects: By detecting the patient's subcutaneous condition through the probe structure, the extent of drug extravasation and the needle insertion location can be accurately determined. The probe structure can upload the subcutaneous image to the display structure, so that medical staff can intuitively view the extent of drug extravasation through the display structure, and accurately find the needle insertion location based on the extent of drug extravasation, thereby improving the accuracy and ease of determining the needle insertion location.

[0015] In one alternative implementation, the display structure is wirelessly connected to the probe structure.

[0016] Beneficial effects: Wireless communication can replace communication cables, thereby improving the simplicity of the syringe structure.

[0017] In one alternative embodiment, the syringe includes an injection unit, the injection unit comprising:

[0018] A syringe is disposed inside the needle housing, and the end of the syringe near the skin to be injected is connected to the injection needle.

[0019] The core rod is sealed and movable inside the syringe at one end;

[0020] A first driving structure is connected to the other end of the core rod and is used to drive the core rod to move.

[0021] Beneficial effects: The first driving structure can drive the core rod to move relative to the syringe barrel in a direction away from the injection needle to draw the local sealing solution into the syringe barrel. At the same time, the first driving structure can also drive the core rod to move relative to the syringe barrel in a direction closer to the injection needle to facilitate the injection of the local sealing solution into the patient's subcutaneous tissue without the need for manual injection by medical staff, thereby achieving the technical effect of improving the ease of injection.

[0022] In one alternative embodiment, the injection needle is detachably connected to the syringe.

[0023] And / or, the injection unit includes:

[0024] A fixed structure is detachably connected to one end of the needle housing near the injection needle tip;

[0025] And / or, a protective structure is connected to one end of the needle housing near the injection needle tip, for protecting the injection needle tip in the first state;

[0026] And / or, the first driving structure includes:

[0027] First driving component;

[0028] A first transmission component is connected to the first driving component, and the first transmission component is connected to the other end of the core rod. The first transmission component is used to drive the core rod to make linear movements under the drive of the first driving component.

[0029] Beneficial effects: With the detachable connection between the injection needle and the syringe, when injecting local sealing solution into the same patient, only the injection needle needs to be replaced, without replacing other components, thus achieving a cost-saving technical effect.

[0030] The fixed structure can protect the injection needle, so that when the injection needle is in the first state, it does not need to come into contact with the outside of the needle shell and cause contamination of the injection needle, thereby achieving the technical effect of improving the hygiene of the injection needle.

[0031] When the injection needle is in the first state, the protective structure can isolate the injection needle from the external environment to avoid contamination of the injection needle, thereby achieving the technical effect of improving the safety of syringe use.

[0032] The first driving structure can drive the core rod to move relative to the syringe barrel in a direction away from the injection needle, so as to draw the local sealing solution into the syringe barrel. At the same time, the first driving structure can also drive the core rod relative to the syringe barrel in a direction closer to the injection needle, so as to inject the local sealing solution into the patient's subcutaneous tissue without the need for manual injection by medical staff, thereby achieving the technical effect of improving the ease of injection.

[0033] In one optional implementation, the protective structure is a flexible component;

[0034] And / or, the first driving member and the first transmission member are disposed on the outside of the syringe, and the first driving structure includes:

[0035] The bent component has one end connected to the core rod and the other end connected to the first transmission component.

[0036] Beneficial effect: Once the injection site is determined, injection can be performed by driving the injection needle through the protective structure, thus achieving the technical effect of simplifying the switching between the first and second states of the injection needle.

[0037] By defining the positions of the first driving component and the first transmission component, their placement inside the syringe is prevented from affecting the space for storing the local sealing liquid. A bending component is used to connect the core rod to the first transmission component; that is, the movement of the bending component drives the movement of the core rod. This allows the length of the first transmission component to be equal to or less than the length of the core rod, thus enabling the core rod to perform liquid inlet and outlet operations, thereby reducing the space occupied by the first driving structure.

[0038] In one optional implementation, the injection unit includes:

[0039] A second driving structure is connected to the syringe and is used to adjust the injection needle to switch between the first state and the second state.

[0040] Beneficial effects: The second driving structure enables the switching between the first and second states of the injection needle without the need for manual driving of the injection needle, thereby improving the ease of switching the state of the injection needle.

[0041] In one optional embodiment, the outer wall of the syringe is provided with a first sensing unit for detecting the liquid level inside the syringe, and / or a second sensing unit is provided inside the needle shell near the injection needle tip for detecting the position of the injection needle tip.

[0042] The injection unit and / or the driving unit are provided with a third sensing unit, which is used to detect the trajectory of the first driving structure driving the core rod to move, and / or the third sensing unit is used to detect the trajectory of the driving unit driving the needle shell to move.

[0043] The syringe includes:

[0044] The storage unit is communicatively connected to the first sensing unit and / or the second sensing unit and / or the third sensing unit; the storage unit is communicatively connected to the display structure.

[0045] And / or, the syringe comprises:

[0046] A control unit is located inside the needle housing, and the control unit is communicatively connected to the drive unit and / or the injection unit.

[0047] Beneficial effects: The first sensing unit can detect the liquid level in the syringe, so as to understand the amount of local sealing solution injected each time, which is helpful for medical staff to understand the amount of medicine injected each time.

[0048] The second sensing unit can detect the position of the injection needle, as well as its first and second states, facilitating medical personnel's understanding of the needle's positional changes during injection. The third sensing unit can detect the movement trajectory of the injection needle and the core rod. The storage unit records the trajectory images detected by the first, second, and third sensing units and uploads them to the display structure, allowing medical personnel to observe and learn about the injection of local sealing fluid through the display structure.

[0049] Medical staff control the movement of the drive unit and injection unit through the control unit to improve the ease of movement of the drive unit and injection unit.

[0050] In one alternative embodiment, the syringe includes:

[0051] The remote control unit is equipped with an operation unit, which is communicatively connected to the control unit.

[0052] Beneficial effects: By operating the remote control unit, medical personnel can control the movement of the drive unit and the injection unit, thereby enabling the injection operation of the syringe and improving the ease of use of the syringe.

[0053] In one alternative embodiment, the syringe includes:

[0054] A power generation unit is connected to the needle housing and / or the drive unit;

[0055] A battery unit, one end of which is electrically connected to the power generation unit, and the other end of which is electrically connected to the injection unit and / or the drive unit and / or the detection unit;

[0056] And / or, the drive unit includes:

[0057] Frame;

[0058] The first rotating structure has one end fixedly connected to the frame;

[0059] A telescopic structure, one end of which is connected to the other end of the first rotating structure;

[0060] The second rotating structure has one end connected to the other end of the telescopic structure, and the other end of the second rotating structure is connected to the needle shell.

[0061] The rotation direction of the first rotating structure is different from that of the second rotating structure.

[0062] Beneficial effects: By setting up a power generation unit, the electrical energy generated by the power generation unit can be stored in the battery unit, so that the syringe does not need mains power, thereby reducing the syringe's consumption of mains power and achieving the technical effect of saving energy.

[0063] By setting up a frame, the positions of the first rotating structure, the telescopic structure, and the second rotating structure can be fixed, thereby improving the stability of their movement. The drive unit allows medical personnel to electrically drive the syringe, eliminating the need for manual operation and thus improving ease of use. The telescopic structure drives the needle shell to extend and retract, enabling adjustment of the injection depth, needle insertion, and needle withdrawal. The first and second rotating structures drive the needle to rotate, allowing for adjustment of the needle's position during injection to complete the administration of the local sealing solution.

[0085] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0086] The following is combined with Figures 1 to 8 The following describes embodiments of the present invention.

[0087] According to an embodiment of the present invention, a syringe is provided, comprising:

[0088] Needle shell 1;

[0089] The injection needle 2 is located at one end of the needle shell 1 near the skin to be injected. The injection needle 2 has a first state in which it is located inside the needle shell 1 and a second state in which it extends out of the needle shell 1.

[0090] Drive unit 3, connected to needle housing 1, is used to drive needle housing 1 to rotate in at least two directions;

[0091] The detection unit 4 is disposed on the needle housing 1. The detection unit 4 is used to form a subcutaneous image when the injection needle 2 is in the first state.

[0092] In this embodiment, the syringe is used to inject a local sealing solution around the extravasated drug after the patient experiences drug extravasation. The local sealing solution blocks the extravasated drug to prevent adverse reactions caused by drug extravasation from affecting the patient's health.

[0093] In the syringe of this embodiment, the detection unit 4 can detect the extent of drug extravasation under the patient's skin in real time, allowing less experienced medical personnel to accurately locate the injection site for the local sealing solution based on the extent of drug extravasation. During the injection of the local sealing solution, the medical personnel can adjust the position of the injection needle 2 through the drive unit 3, enabling real-time adjustment of the injection angle of the injection needle 2, and surrounding the extravasated drug with the local sealing solution. Based on this, the injection of the local sealing solution can be performed by less experienced medical personnel, thereby achieving the technical effect of reducing the pressure on medical resources.

[0094] Of course, in other embodiments, it can also be used in other scenarios requiring drug injection. For example, the syringe can be used in cases of subcutaneous injection or other localized injections.

[0095] Furthermore, when the detection unit 4 detects subcutaneous drug extravasation, the injection needle 2 is in a first state, meaning it is inside the needle housing 1. Once the detection unit 4 detects the insertion position of the injection needle 2, it enters a second state, extending outside the needle housing 1, to complete the insertion and injection of the local sealing solution. This avoids the injection needle 2 remaining outside the needle housing, preventing increased contact between the needle 2 and bacteria and thus contamination, thereby improving the safety of the injection process.

[0096] In addition, in this embodiment, the detection unit 4 includes:

[0097] The probe structure is located at the end of the needle housing 1 closest to the skin;

[0098] The display structure is connected to the probe structure.

[0099] Based on this, the probe structure can be used to detect the patient's subcutaneous condition, so as to accurately determine the extent of drug extravasation and the needle insertion location. The probe structure can upload subcutaneous images to the display structure, so that medical staff can intuitively view the extent of drug extravasation through the display structure, and accurately find the needle insertion location based on the extent of drug extravasation, thereby achieving the technical effect of improving the ease of determining the needle insertion location.

[0100] Preferably, the probe structure is an ultrasonic probe, and the display structure can be a mobile phone, specifically a software installed within the phone. This technology is mature and will not be elaborated further. Of course, in other embodiments, the display structure can be a monitor or a computer. Compared to other embodiments, using a mobile phone as the display structure in this embodiment improves the ease of moving the display structure, thereby enhancing the ease of use of the syringe.

[0101] Furthermore, in this embodiment, the display structure and the probe structure are wirelessly connected. For example, the probe structure may have a built-in Wi-Fi module, allowing the probe structure and the display structure to communicate via Wi-Fi. Wi-Fi communication is a mature technology and will not be elaborated upon further. Alternatively, the display structure may be wirelessly connected to the probe structure via a Bluetooth module.

[0102] Of course, in other embodiments, the display structure can be connected to the probe structure via a communication cable. Compared to other embodiments, this embodiment does not require a communication cable, thus achieving the technical effect of improving the simplicity of the syringe structure.

[0103] In addition, combined Figures 5 to 7 As shown, in this embodiment, the injection unit 6 includes:

[0104] The syringe 601 is housed inside the needle casing 1. The end of the syringe 601 closest to the skin to be injected is connected to the injection needle 2. That is, the syringe 601 extends along... Figure 6 The lower part, as shown, is connected to an injection needle 2;

[0105] The core rod 602 is sealed and movable inside the syringe 601 at one end;

[0106] The first drive structure 605 is connected to the other end of the core rod 602 and is used to drive the core rod 602 to move.

[0107] Based on this, the first driving structure 605 can drive the core rod 602 to move relative to the syringe 601 in a direction away from the injection needle 2, so as to draw the local sealing solution into the syringe 601. At the same time, the first driving structure 605 can also drive the core rod 602 to move relative to the syringe 601 in a direction closer to the injection needle 2, so as to inject the local sealing solution into the patient's subcutaneous tissue without the need for manual injection by medical staff, thereby achieving the technical effect of improving the ease of injection.

[0108] The first drive structure 605 includes:

[0109] The first driving component is fixed to the outside of the syringe 601, specifically to the inner wall of the needle housing 1;

[0110] The first transmission component is connected to the first driving component and is connected to the other end of the core rod 602. The first transmission component is used to drive the core rod 602 to make linear motion under the drive of the first driving component.

[0111] Based on this, the first driving member drives the core rod 602 to move linearly relative to the syringe 601 through the first transmission member, so as to improve the ease of use of the syringe by electrically driving the extraction and injection of the local sealing liquid.

[0112] Specifically, in combination Figure 7 As shown, the first driving component is a first electric motor 6051, and the first transmission component includes a threaded first rotating screw 6052 and a first screw nut 6054. The shaft of the first electric motor 6051 is coaxially connected to the first rotating screw 6052, which is rotatably connected inside the needle housing 1. The first screw nut 6054 is threadedly connected to the first rotating screw 6052 and is connected to the core rod 602. The rotation of the first electric motor 6051 drives the rotation of the first rotating screw 6052, which in turn drives the core rod 602 to move linearly along the first rotating screw 6052 via the first screw nut 6054, thus achieving linear movement of the core rod 602 relative to the syringe 601.

[0113] Preferably, combined with Figure 7 As shown, the first driving member and the first transmission member are located on the outside of the syringe 601. Based on this, it can be avoided that the first driving member and the first transmission member being located on the inside of the syringe 601 will affect the space for storing the sealing liquid inside the syringe 601.

[0114] Furthermore, the first drive structure 605 includes:

[0115] The bent component 6053 is connected at one end to the core rod 602 and at the other end to the first transmission component. The bent component 6053 can be U-shaped.

[0116] Of course, in other embodiments, the shape of the bending member 6053 can be adjusted according to the design of the syringe. Alternatively, in other embodiments, the bending member 6053 may not be provided, and the core rod 602 may be directly connected and fixed to the first lead screw nut 6054. In this case, the length of the first rotating lead screw 6052 needs to be twice the length of the core rod 602 to achieve the operation of liquid inlet and outlet by driving the core rod 602 through the first lead screw nut 6054. Compared with other embodiments, this embodiment uses the bending member 6053 to connect the core rod 602 and the first lead screw nut 6054, that is, the movement of the bending member 6053 can drive the movement of the core rod 602, so that the length of the first rotating lead screw 6052 is equal to or less than the length of the core rod 602 to achieve the liquid inlet and outlet operation of the core rod 602, thereby achieving the technical effect of reducing the space occupied by the first drive structure 605.

[0117] In other embodiments, depending on the structural design of the syringe, the first driving component is a hydraulic cylinder, and the first transmission component is a telescopic rod. The linear movement of the telescopic rod, driven by the hydraulic cylinder, also achieves the linear movement of the core rod 602 relative to the syringe barrel 601. Compared to other embodiments, this embodiment, by converting the rotational motion of the first driving component into the linear motion of the core rod 602, reduces the length of the syringe along the direction of movement of the core rod 602, thereby achieving the technical effect of reducing the spatial limitations of the syringe.

[0118] In addition, the needle shell 1 and the syringe 601 are made of transparent material to facilitate observation of the liquid level inside the syringe 601.

[0119] Furthermore, in this embodiment, combined with Figure 5 and Figure 6 As shown, the second driving structure 606 is connected to the syringe 601. The second driving structure 606 is used to adjust the injection needle 2 to switch between the first state and the second state. By realizing the switch between the first state and the second state of the injection needle 2 through the second driving structure 606, the position of the injection needle 2 does not need to be manually adjusted, thereby improving the ease of state switching of the injection needle 2.

[0120] The second drive structure 606 includes:

[0121] The second driving component is fixed inside the needle housing 1;

[0122] The second transmission component is connected to the second driving component. The side of the second transmission component is connected to the syringe 601. The second transmission component is used to drive the syringe 601 to make linear movements under the drive of the second driving component.

[0123] Specifically, the second driving component is a second electric motor 6061, fixed to the inner wall of the needle housing 1. The second transmission component includes a threaded second rotating screw 6062 and a screw nut 6064. The shaft of the second electric motor 6061 is coaxially connected to the second rotating screw 6062, which is rotatably connected inside the needle housing 1. The second screw nut 6064 is threadedly connected to the second rotating screw 6062, and its side is connected to the syringe barrel 601. The rotation of the second driving component drives the rotation of the second rotating screw 6062, which in turn drives the second screw nut 6064 to move linearly along the screw 6062, thus realizing the linear movement of the syringe barrel 601 relative to the needle housing 1, and thereby achieving the switching between the first and second states of the injection needle 2.

[0124] Furthermore, the second drive structure 606 includes:

[0125] An intermediate component 6063 is disposed on one side of the syringe 601 and the first driving component, that is, the intermediate component 6063 is sleeved on the outside of the syringe 601 and the first driving structure 605, and can fix the position of the syringe 601 and the first driving structure 605. Specifically, the first driving component is fixed inside the intermediate component 6063, specifically, it can be fixed to the inner wall of the intermediate component 6063. The intermediate component 6063 has a slot along the axial direction of the first rotating screw 6052. The first rotating screw 6052 is inserted into the slot, which can fix the position of the first rotating screw 6052, thereby achieving the technical effect of improving the stability of the movement of the syringe 601 and the first driving structure 605 during the movement of the second driving structure 606.

[0126] The intermediate component 6063 can be a cylindrical structure and made of transparent material. Of course, in other embodiments, the shape of the intermediate component 6063 can be adjusted so that the syringe 601 and the first driving structure 605 are disposed within the intermediate component 6063.

[0127] Of course, in other embodiments, depending on the structural design of the syringe, the second driving component can be a hydraulic cylinder, and the second transmission component can be a telescopic rod. The linear movement of the telescopic rod driven by the hydraulic cylinder can also achieve the linear movement of the syringe barrel 601 relative to the needle housing 1, thereby realizing the transition of the injection needle 2 between the first and second states. Compared to other embodiments, this embodiment saves the space required for the syringe in the vertical direction by using the rotation of the second driving component to drive the linear movement of the syringe barrel 601, thus achieving the technical effect of reducing the space limitations of the syringe.

[0128] In addition, in this embodiment, two second drive structures 606 are provided along the circumferential direction of the syringe 601. The two second drive structures 606 synchronously drive the linear movement of the syringe 601 to improve the stability of the movement of the syringe 601. Of course, in other embodiments, the number of second drive structures 606 can be adjusted according to the design of the syringe. The number of second drive structures 606 can be one, three, or more.

[0129] In addition, combined Figures 1 to 5 As shown, in this embodiment, the syringe includes an injection unit 6, which includes:

[0130] The fixing structure 603 is detachably connected to one end of the needle housing 1 near the injection needle tip 2;

[0131] The protective structure 604 is connected to the end of the needle housing 1 near the injection needle 2, and is specifically located in the mounting hole of the fixing structure 603 near the injection needle 2. The protective structure 604 is used to protect the injection needle 2 in the first state.

[0132] The fixing structure 603 includes a second cavity, in which the syringe 601 and the injection needle 2 are located. The fixing structure 603 can protect the injection needle 2, so that when the injection needle 2 is in the first state, it does not need to come into contact with the outside of the needle shell 1, thus avoiding contamination of the injection needle 2, thereby improving the hygiene of the injection needle 2.

[0133] Furthermore, by embedding a protective structure 604 at one end of the fixed structure 603 near the injection needle 2, when the injection needle 2 is in the first state, the protective structure 604 can isolate the injection needle 2 from the external environment to avoid contamination of the injection needle 2, thereby achieving the technical effect of improving the safety of syringe use.

[0134] Specifically, one side of the fixing structure 603 is fixedly connected to the probe structure, and the fixing structure 603 and the needle shell 1 are detachably connected by threads to improve the stability of the connection between the fixing structure 603 and the needle shell 1.

[0135] Preferably, the protective structure 604 is a flexible component, such as a butyl rubber stopper. Based on this, once the injection position is determined, injection can be performed by driving the injection needle 2 through the protective structure 604, thereby achieving the technical effect of simplifying the transition between the first and second states of the injection needle 2.

[0136] Of course, in other embodiments, the material of the protective structure 604 can be adjusted depending on the design of the syringe.

[0137] In other embodiments, the fixing structure 603 and the needle shell 1 can be fixed by a clamp connection.

[0138] In addition, in this embodiment, a fixing seat is provided in the second cavity of the fixing structure 603, and a fixing hole is provided on the fixing seat. When the injection needle 2 is in the first state, the tip of the injection needle 2 is located in the fixing hole. The fixing hole can fix the position of the injection needle 2, ensuring that the injection needle 2 moves linearly during the transition between the first and second states, thereby improving the accuracy of the position movement of the injection needle 2. In other embodiments, the fixing seat may be omitted.

[0139] Of course, in other embodiments, only the fixing structure 603 or only the protective structure 604 may be provided. Any solution that can protect the injection needle 2 and enable the injection needle 2 to have a first state and a second state is within the scope of protection of this application.

[0140] In this embodiment, the injection needle 2 is detachably connected to the syringe 601. Therefore, when injecting the local sealing solution into the same patient, only the injection needle 2 needs to be replaced. That is, when multiple injections of the local sealing solution are required into the same patient, after each injection, the syringe with the disassembled injection needle 2 can be placed in a low-temperature environment. When injecting the local sealing solution into the same patient again, a new injection needle 2 can be installed on the syringe 601 without replacing other components, thus achieving a cost-saving effect.

[0141] Of course, in other embodiments, the syringe 601 is detachably connected to the needle housing 1 or the syringe 601 is detachably connected to the intermediate member 6063, and the core rod 602 is detachably connected to the bending member 6053, that is, the core rod 602 is detachably connected along... Figure 7 The top shown has a threaded hole, and the corresponding position of the bent part 6053 has threads. The bent part 6053 is an elastic element, for example, the bent part 6053 is made of elastic metal. The needle shell 1 is along... Figure 1The left end of the syringe 601 has an opening connecting to the outside. The surface of the syringe 601 has a first thread. When the syringe 601 is detachably connected to the needle housing 1, the second lead screw nut 6064 has an annular limiting member, the inner wall of which has a second thread. When the syringe 601 is detachably connected to the intermediate member 6063, the inner wall of the intermediate member 6063 has a second thread. Specifically, during the installation of the syringe 601, medical personnel can use external force to bend the bending member 6053, causing elastic deformation such as torsion, to prevent the position of the bending member 6053 from affecting the installation of the syringe 601. The syringe 601 is placed inside the needle housing 1 through the opening, and its installation and fixation are achieved through the threaded connection of the first and second threads. After the syringe 601 is installed, the bent part 6053, after the external force is removed, returns to its original shape under the action of elastic force. The core rod 602 is then disassembled to the outside of the syringe 601. After the core rod 602 is rotated to achieve a threaded connection with the bent part 6053, the core rod 602 is then installed inside the syringe 601, thus completing the connection and fixation between the core rod 602 and the bent part 6053.

[0142] In addition, combined Figure 1 As shown, in this embodiment, the driving unit 3 includes:

[0143] Frame 301;

[0144] The first rotating structure 302 is fixedly connected at one end to the frame 301;

[0145] The telescopic structure 303 is connected at one end to the other end of the first rotating structure 302;

[0146] The second rotating structure 304 has one end connected to the other end of the telescopic structure 303, and the other end of the second rotating structure 304 is connected to the needle shell 1.

[0147] The rotation direction of the first rotating structure 302 is different from that of the second rotating structure 304.

[0148] By setting the frame 301, the positions of the first rotating structure 302, the telescopic structure 303, and the second rotating structure 304 can be fixed, thereby improving the stability of their movement. The telescopic structure 303 drives the needle housing 1 to extend and retract along the Y-axis, enabling adjustment of the injection depth, needle insertion, and needle withdrawal of the injection needle 2. The first rotating structure 302 drives the injection needle 2 to rotate around the Z-axis, and the second rotating structure 304 drives it to rotate around the X-axis. This allows the injection position of the injection needle 2 to be adjusted during injection using the first rotating structure 302, the telescopic structure 303, and the second rotating structure 304, thus completing the injection of the local sealing solution.

[0149] Specifically, in combination Figure 3 and Figure 4 As shown, the first rotating structure 302 includes:

[0150] The first connector 3021 can be a first connecting rod. The first connector 3021 is an "L"-shaped bent part. One end of the first connecting rod is fixedly connected to the frame 301, and the other end of the first connecting rod is provided with a first mounting cavity.

[0151] The third driving component 3022 can be a motor, and the third driving component 3022 is located in the first mounting cavity.

[0152] The telescopic structure 303 includes:

[0153] The second connecting member 3031 can be a second connecting rod, which is an "L"-shaped bent member. One end of the second connecting rod is connected to the rotating shaft of the third driving member 3022, and the other end of the second connecting rod is provided with a second mounting cavity.

[0154] The fourth driving component 3032 can be a hydraulic cylinder, which is located in the second mounting cavity.

[0155] The second rotating structure 304 includes:

[0156] The third connecting part 3041 can be a third connecting rod, which is an "L"-shaped bent part. One end of the third connecting rod is connected to the telescopic end of the hydraulic cylinder, and the other end of the third connecting rod is provided with a third mounting cavity.

[0157] The fifth driving component 3042 can be a motor. The fifth driving component 3042 is located in the third mounting cavity, and the rotating shaft of the fifth driving component 3042 is fixedly connected to the needle housing 1.

[0158] In other embodiments, depending on the design of the syringe, the first connector 3021, the second connector 3031, and the third connector 3041 may also be linear or other shapes. As long as the fixing of the third drive member 3022, the fourth drive member 3032, and the fifth drive member 3042 can be achieved, they are all within the protection scope of this application.

[0159] Of course, in other embodiments, the specific structures of the first rotating structure 302, the telescopic structure 303, and the second rotating structure 304 can be adjusted according to the different designs of the syringe. The first connecting member 3021, the second connecting member 3031, and the third connecting member 3041 can also be plate-shaped structures.

[0160] In other embodiments, the direction of movement of the injection needle 2 can be adjusted depending on the use and design of the syringe.

[0161] In addition, in this embodiment, the outer wall of the syringe 601 is provided with a first sensing unit, which is used to detect the liquid level inside the syringe 601.

[0162] The outer wall of the needle housing 1 is provided with a second sensing unit, which is used to detect the position of the injection needle 2, that is, the position of the injection needle 2 in the first state, the second state, and the position inside the needle housing 1 during the injection process.

[0163] Furthermore, a third sensing unit is provided within the injection unit 6 and the driving unit 3. The third sensing unit includes:

[0164] The first sensor is located on the inner wall of the needle housing 1 and is used to detect the trajectory of the first driving structure 605 driving the core rod 602.

[0165] The second sensor is located on the outer wall of the first connector 3021 and is used to detect the movement trajectory of the second connector 3031 driven by the first rotating structure 302, that is, to detect the trajectory of the injection needle 2 rotating around the Z-axis.

[0166] The third sensor is located on the outer wall of the second connector 3031 and is used to detect the movement of the third connector 3041 driven by the telescopic structure 303. That is, the third sensor detects the telescopic trajectory of the injection needle 2 along the Y-axis.

[0167] The fourth sensor, located on the outer wall of the third connector 3041, is used to detect the movement of the needle shell 1 driven by the second rotating structure 304, that is, the fourth sensor detects the trajectory of the injection needle 2 rotating around the X-axis.

[0168] In this embodiment, the first sensing unit can be a capacitive liquid level sensor, and the second and third sensing units can both be two-dimensional vision sensors.

[0169] The fourth sensing unit, which can be a distance sensor, is located on the inner wall of the needle housing 1 and is used to detect the distance between the end of the needle housing 1 near the fixed structure 603 and the syringe 601. That is, by limiting the minimum and maximum distance between the end of the needle housing 1 near the fixed structure 603 and the syringe 601, the second driving structure 606 stops moving after the injection needle 2 is in the first state and the second state.

[0170] Of course, in other embodiments, depending on the design of the syringe, the fourth sensing unit can also detect the distance between the fixed structure 603 and the syringe 601. In other embodiments, depending on the design of the syringe, the types of the first, second, third, and fourth sensing units can be adjusted. Alternatively, the fourth sensing unit can be omitted, and the distance between the syringe 601 and the needle shell 1 can be determined by the length of the injection needle 2 outside the needle shell 1.

[0171] In other embodiments, depending on the design of the syringe, the third sensing unit may be provided only in the injection unit 6 or only in the drive unit 3.

[0172] In addition, combined Figure 8 As shown, in this embodiment, the syringe includes:

[0173] The control unit, which is communicatively connected to the drive unit 3 and the injection unit 6, is located inside the needle housing 1. The control unit can control the movement of the first drive structure 605, the second drive structure 606, the first rotating structure 302, the telescopic structure 303, and the second rotating structure 304. The control unit is a control circuit, and its structure is a mature technology, so it will not be described in detail here.

[0174] The remote control unit 5 includes an operating unit that is communicatively connected to the control unit. The operating unit, through the control unit, controls the movement of the drive unit 3 and the injection unit 6. Specifically, the remote control unit 5 can be a remote controller. The operating unit includes:

[0175] Casing 501;

[0176] The switch 502 is used to open and close the communication connection of the remote control unit 5.

[0177] The indicator light 509 is connected to the fourth sensing unit. When the fourth sensing unit detects that the end of the needle shell 1 near the fixed structure 603 is at its minimum or maximum distance from the syringe 601, the indicator light 509 is red. When the fourth sensing unit detects that the end of the needle shell 1 near the fixed structure 603 is between the minimum and maximum distance from the syringe 601, the indicator light 509 is green.

[0178] The needle insertion key 503 is communicatively connected to the second drive structure 606. The needle insertion key 503 is used to drive the injection needle 2 to extend out of the needle shell 1, that is, the injection needle 2 is in the second state.

[0179] The needle retraction key 504 is communicatively connected to the second drive structure 606. The needle retraction key 504 is used to drive the injection needle 2 to retract into the needle shell 1, that is, the injection needle 2 is in the first state.

[0180] The first drive key 505 is spherical and rotatably connected in the first mounting groove 506 provided in the housing 501. The diameter of the groove opening of the first mounting groove 506 is smaller than the diameter of the first drive key 505 to prevent the first drive key 505 from falling out of the housing 501. The first drive key 505 is communicatively connected to the telescopic structure 303 and the second rotating structure 304.

[0181] Specifically, in combination Figure 1 and Figure 3As shown, rotating the first drive key 505 upwards drives the second rotating structure 304 to move the needle shell 1 upwards around the X-axis. Rotating the first drive key 505 downwards drives the second rotating structure 304 to rotate the needle shell 1 downwards around the X-axis. Rotating the first drive key 505 to the left drives the telescopic structure 303 to retract the needle shell 1 to the left. Rotating the first drive key 505 to the right drives the telescopic structure 303 to extend the needle shell 1 to the right.

[0182] The second drive key 507 is spherical and has the same structure as the first drive key 505. The second drive key 507 is located to one side of the first drive key 505 and is also rotatably connected within the second mounting groove 508 provided in the housing 501. The diameter of the opening of the second mounting groove 508 is smaller than the diameter of the second drive key 507, thus preventing the second drive key 507 from falling out of the housing 501. Further details are omitted here. The second drive key 507 is communicatively connected to the first rotating structure 302 and the first drive structure 605.

[0183] Specifically, in combination Figure 2 As shown, rotating the second drive key 507 upwards drives the first rotating structure 302 to rotate the needle shell 1 backwards; rotating the second drive key 507 downwards drives the first rotating structure 302 to rotate the needle shell 1 forwards. Rotating the second drive key 507 to the left moves the core rod 602 to the left, thus performing the liquid inlet operation; rotating the second drive key 507 to the right moves the core rod 602 to the right, thus performing the liquid outlet operation.

[0184] A storage unit is located inside the needle housing 1. The storage unit is communicatively connected to the first, second, third, and fourth sensing units, and also to the display structure. Based on this, during injection, the storage unit statistically collects and transmits the movement trajectory of the injection needle 2, the movement trajectory of the core rod 602, and the amount of local sealing solution injected to the display structure in the form of images. This allows medical personnel to view the data and learn the local sealing solution operation process later.

[0185] In this embodiment, the control unit and the drive unit 3 are connected wirelessly, as are the control unit and the injection unit 6, and the control unit and the remote control unit 5 are connected wirelessly. Based on this, no wire connection is required, thereby achieving the technical effect of improving the structural simplicity of the syringe.

[0186] Of course, in other embodiments, only the second sensing unit, the third sensing unit, the fourth sensing unit and the storage unit may be provided, or only the first sensing unit, the third sensing unit, the fourth sensing unit and the storage unit may be provided, or only the control unit may be provided.

[0187] In other embodiments, the indicator light 509 may not be provided. The control unit is directly connected to the fourth sensing unit. When the fourth sensing unit detects that the end of the needle shell 1 near the fixed structure 603 is at the minimum or maximum distance from the syringe 601, the control unit controls the first driving structure 605 to stop moving based on the detection result of the fourth sensing unit. Even if the second driving key 507 is driven, the first driving structure 605 will no longer drive the movement of the core rod 602.

[0188] Furthermore, in this embodiment, the syringe includes:

[0189] The power generation unit is connected to the outside of the needle housing 1;

[0190] The battery unit is electrically connected at one end to the power generation unit and at the other end to the injection unit 6, the drive unit 3, and the detection unit 4. At the same time, the battery unit can also be electrically connected to the first sensing unit, the second sensing unit, the third sensing unit, and the fourth sensing unit, so that the syringe does not require mains power, thereby reducing the syringe's mains power consumption and achieving the technical effect of saving energy.

[0191] The power generation unit can be a solar generator, and the battery unit is an energy storage battery. When the syringe is idle, it can be placed outdoors in the sun, and the power generation unit can convert solar energy into electrical energy and store the electrical energy in the battery unit to prepare for the use of the syringe.

[0192] In other embodiments, the power generation unit may be connected only to the outside of the drive unit 3, or it may be connected to both the needle housing 1 and the drive unit 3. The battery unit may be electrically connected only to the injection unit 6, only to the drive unit 3, or only to the detection unit 4.

[0193] In addition, in this embodiment, the needle housing 1 is provided with a start button. Pressing the start button can control the connection between the control unit inside the needle housing 1 and the remote control unit 5, control the drive unit 3, the first drive structure 605 and the second drive structure 606 to be in standby or off state, and control the detection unit 4, the first sensing unit, the second sensing unit, the third sensing unit and the fourth sensing unit to be in working or off state.

[0194] Furthermore, in this embodiment, the injection needle 2 is made of medical-grade stainless steel, which gives it corrosion resistance and high mechanical strength. Of course, in other embodiments, the material used to manufacture the injection needle 2 can be adjusted depending on the syringe design and actual use.

[0195] The specific usage process of the syringe in this embodiment is as follows:

[0196] First, the fixing structure 603 is removed, and the injection needle 2 is immersed in the local sealing solution. The first driving structure 605 drives the movement of the core rod 602, so that the syringe 601 is filled with local sealing solution.

[0197] Then, the fixing structure 603 is installed on the needle housing 1, with the injection needle 2 located in the fixing hole of the fixing base, at which point the injection needle 2 is in the first state. At the same time, by turning on the power switch 502 and the start button, the communication connection between the remote control unit 5 and the control unit is established, and the detection unit 4, the first sensing unit, the second sensing unit, the third sensing unit, and the fourth sensing unit are opened.

[0198] Next, medical staff use remote control unit 5 to drive the movement of the first rotating structure 302, the telescopic structure 303, and the second rotating structure 304 to adjust the position of the probe structure. Specifically, the position of the probe structure is first adjusted to the skin surface where the patient may experience drug extravasation. The subcutaneous condition of the patient is viewed through the display structure. Then, the position of the probe structure is adjusted to determine the needle insertion point based on the extent of drug extravasation.

[0199] Subsequently, after the needle insertion position is determined, medical personnel control the movement of the second drive structure 606 via the remote control unit 5, causing the injection needle 2 to pass through the protective structure 604 to the second state. At this point, the injection needle 2 can be inserted into the patient's subcutaneous tissue. The medical personnel then drive the first drive structure 605 to control the core rod 602 to perform a retraction operation. When the medical personnel observe that there is no blood return inside the needle shell 1, they drive the first drive structure 605 to inject the local sealing solution. Immediately afterward, after one injection, the first sensing unit uploads the amount of injected local sealing solution to the storage unit, and then uploads it to the display structure through the storage unit, so that medical personnel can understand the amount of medication injected in subsequent training.

[0200] Medical staff can control the drive unit 3 through the remote control unit 5 to adjust the position of the injection needle 2, thereby changing the injection angle and the injection volume of the injection needle 2 to achieve fan-shaped drug delivery and complete the injection of local sealing solution at the injection position.

[0201] Finally, by changing the needle insertion position and repeating the above operation, the injection of the local sealing solution is completed until the area around the extravasated drug solution is filled with the local sealing solution.

[0202] During this process, the display structure can record all images and data of the injection, so that medical staff can observe and learn from it later.

[0203] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
