[0002] Medical therapeutic substances such as drugs, biologics, cells, and implants play an active role in treatment, and therapeutic goals are often achieved through oral and injection methods. For the implantation of high-viscosity and semi-solid medical therapeutic substances, strong thrust is required to achieve this through injection methods. In tough tissues such as dermis, tendons and ligaments, as well as hard bone tissue, the dense tissue structure increases the difficulty of injection. Bone cement is the most typical high-viscosity medical therapeutic substance and is also one of the most difficult to use.

[0003] Therefore, there are many methods and techniques presented:

[0004] The Chinese patent with publication number CN114533239A relates to a medical bone cement injection device with self-adjusting injection pressure. The device adjusts the working pressure while injecting bone cement into the patient's body, which can avoid insufficient thrust affecting the diffusion of bone cement and avoid overflow of bone cement during the pressurization process.

[0005] The Chinese patent with publication number CN102159262B relates to a bone cement container system, which extends longitudinally through a power piston penetrating a fluid container so that high-viscosity bone cement is transported from the bone cement container to bone tissue via a sleeve.

[0006] The Chinese patent with publication number CN105012005B relates to a bone cement injection device and method, which uses an inner tube to be arranged in a set channel, and the outer tube and the inner tube are rotated to match, and each layer of the first injection hole is matched with a layer of the second injection hole. When the inner tube is rotated to a specific angle, at least one layer of the first injection hole is connected to the second injection hole of its corresponding layer, and the first injection holes of the remaining layers are staggered with the second injection holes of their corresponding layers. It is convenient to adjust the injection position of bone cement and realize the directional injection of bone cement.

[0007] Chinese patent publication number CN116650090A discloses a bone cement injection device and method based on the drawing stage state, wherein bone cement for pathological vertebral fractures is injected through a syringe, and the bone cement is cooled through a liquid cooling device so that the bone cement is at room temperature in a sterilization container.

[0008] The Chinese patent with publication number CN116870297A discloses a quantitative injection device. The dosage sleeve is used to indicate the dosage, the rotating assembly forms a second ratchet engaged with the first ratchet, and the front end of the rotating assembly is formed with a third ratchet. The push rod assembly forms a fourth ratchet engaged with the third ratchet, the rotating assembly can drive the push rod assembly to rotate, and the push rod assembly can move in the front-rear direction relative to the threaded sleeve. The injection dosage cannot be adjusted steplessly.

[0009] Chinese patent publication number CN115363733A discloses a bone cement injection device and an injection method thereof, which automatically performs bone cement injection, and the injection volume and injection speed of bone cement are controllable, thereby improving the quality and success rate of surgery.

[0010] International patent WO2022 / 16751A1 relates to an injection device including a drive device, a plunger, and an intermediate member, wherein the intermediate member is arranged between the drive device and the plunger and is releasably engaged with the plunger, thereby selectively transmitting force from the drive device to the plunger.

[0011] International patent WO2022 / 16348A1 relates to an injection device and a control method, which uses a first detection unit for detecting the direct torque of a direct-acting motor and a second detection unit for detecting the rotational torque of a rotary motor, monitors the direct torque and the rotational torque, and controls the direct-acting motor and the rotary motor so that the bushing is engaged with the screw spline.

[0012] International patent WO2022 / 17983A1 relates to an automatic injection device housing latch for receiving and operating a syringe to facilitate injection of a medicament into a subject. The device includes an openable cover that allows the insertion and removal of the syringe, a cover latch that can be operated to lock the cover in a closed position, and a needle safety shield that moves between a first retracted position and a second extended position. When the safety shield is in the first position, the cover latch cannot be released, preventing the cover from being opened. When the safety shield is in the second position, the cover latch is released, allowing the cover to be opened.

[0013] The above technologies are all single functions and cannot simultaneously solve the precise control of implantation site, depth, temperature, dosage, and pressure. Corresponding supporting equipment is required to achieve precise treatment of medical therapeutic substances. Summary of the invention

[0052] like Figure 1 As shown, a multifunctional intelligent medical syringe mainly includes a main body shell, a storage and transportation device, a power device, a temperature control device, a depth measuring device, an injection device and an intelligent center;

[0053] The main shell is composed of a shell 1 and a three-dimensional cavity therein;

[0054] The storage and transportation device comprises a hollow tube 2 and a piston 3.

The front compartment 4 is provided with a material inlet and outlet 6 at the end away from the piston 3, and the rear compartment 5 is provided with a kinetic energy medium inlet and outlet 7 at the end away from the piston 3.

[0055] The power device includes a pressure regulating pump 8 and a pressure reducer 9. A kinetic energy delivery pipe 10 is provided between the pressure regulating pump 8 and the kinetic energy medium inlet and outlet 7. The pressure reducer 9 is installed on the kinetic energy delivery pipe 10.

[0056] The temperature control device is composed of a sealing layer 11, a phase change material layer 12 for controlling the temperature, and a micro remote sensing temperature sensor 13. The sealing layer and the phase change material layer are arranged between the shell 1 and the hollow tube 2. A closed gap layer is formed between the sealing layer 11 and the hollow tube 2. The phase change material layer 12 is arranged in the sealed gap layer. The front cabin 4 and the rear cabin 5 are each equipped with at least one micro remote sensing temperature sensor 13, which is used to send the temperature information of the front cabin 4 and the rear cabin 5 to the smart center, so that the smart center can perform precise control according to the setting conditions;

[0057] The depth measuring device 17 is a laser distance measuring device, which uses the laser time-of-flight method to measure the depth of the injection needle entering the body;

[0058] The injection device includes an injection needle 14, a displacement drive device, a solenoid valve 15 and a material transport pipe 16. One end of the material transport pipe 16 is connected to the material inlet and outlet 6 of the front cabin 4, and the other end is connected to the injection needle 14 through the solenoid valve 15. The front cabin 4 and the rear cabin 5 are each equipped with at least one micro remote sensing pressure sensor 18 to detect and regulate the injection of the medical treatment substance and the pressure of the site;

[0059] The displacement drive device includes a drive motor 20, a rack 21, a gear 22, and a gear seat 23. The front end of the rack 21 is fixed to the depth measuring device 17, and the rear end is fixed to the wall of the front cabin 4. The gear seat 23 is fixed to the solenoid valve 15. The gear 22 is tightly engaged with the rack 21. When the drive motor 20 drives the gear 22 to rotate, the gear seat 21 generates linear motion, forming the advance and retreat of the injection needle, and precise control is achieved through the intelligent center.

[0060] The intelligent center has at least one microcomputer 19 that can collect, store and analyze data. The microcomputer is connected to the pressure regulating pump 8, the pressure reducer 9, the micro remote temperature sensor 18, the micro remote pressure sensor 13, the depth measuring device, and the displacement drive device to accurately control the pressure and temperature of the front and rear compartments of the injection device and the solenoid valve and the depth measuring device. The intelligent center has manual, remote and intelligent voice setting and control capabilities, which simplifies and speeds up the application of the injection device.

[0061] The housing 1 is made of at least one of metal, inorganic, organic and composite materials, and is made by at least one of casting, machining, engraving and 3D printing, and is used to hold and / or fix the syringe, protect the cavity and its contents, and has no limitation on size and weight;

[0062] The three-dimensional cavity inside the shell 1 forms at least one three-dimensional space inside the shell for accommodating and installing all devices and parts of the syringe, and its shape and size are not limited.

[0063] The hollow tube 2, piston 3 and kinetic energy delivery tube 10 are all made of at least one of metal material or / and, inorganic material or / and, organic material or / and, composite material, and are used for transporting and storing materials and injection kinetic energy, and their size and shape are not limited;

[0064] The hollow tube 2 is a closed hollow tube, and its cross-sectional shape is but not limited to a circle, an ellipse, a square, a rectangle, or a rhombus. Its front end has at least one material inlet and outlet 6, and its rear end has at least one kinetic medium inlet and outlet 7. The size and shape of the hollow tube and the two inlets and outlets are not limited.

[0065] The piston 3 is a cylindrical entity that is sealed and matched with the inner wall of the hollow tube 2, and separates the front compartment 4 and the rear compartment 5. The front compartment stores medical treatment substances, and the rear compartment stores the injection kinetic energy. The piston 3 can transfer the injection kinetic energy of the rear compartment to the medical treatment substances in the front compartment, laying the foundation for the realization of injection. There is no limitation on the shape, size and weight of the piston.

[0066] When the pressure regulating pump 8 increases the pressure of the rear chamber to greater than 1 atmosphere, the medical treatment substance can be injected out of the syringe. When the pressure regulating pump reduces the pressure of the rear chamber to less than 1 atmosphere, the medical treatment substance can be sucked into the syringe. The kinetic energy medium can be but is not limited to gas and / or liquid.

[0067] The pressure reducer 9 is placed on the kinetic energy delivery pipe and is sealed and connected thereto. It is controlled by the intelligent center to precisely control the pressure inside the rear cabin.

[0068] The sealing layer 11 is made of at least one of metal, inorganic, organic and composite materials. At least one layer of the sealing layer is prepared on the periphery of the hollow tube to form at least one layer of the closed gap layer. The thickness and size of the gap layer are not limited.

[0069] The phase change material layer 12 is a phase change material formed in the closed gap layer, and the temperature rise and fall of the hollow tube is regulated by material phase change. The phase change material is at least one of titanium hydride or / and, manganese hydride or / and, nickel hydride or / and, vanadium hydride or / and, lanthanide metal hydride or / and, etc.;

[0070] In the electroinduced phase transition, the action of the electric field can change the crystal structure, charge distribution or other properties of the material, resulting in a change in the physical state of the material. For example, the electroinduced phase transition of metal hydrides will affect the interaction between hydrogen and metal, change the adsorption and desorption properties of the material, and then affect the phase transition behavior, so that the phase transition temperature can be controlled between 0°C and 100°C. The direction of the electric field can also be changed to affect the phase transition of the metal hydride, making the electric field in a specific direction more sensitive. Metal hydrides can also be doped, modified or synthesized to enhance their responsiveness to the electric field.

[0071] Such changes can affect the electrical properties of the material, such as conductivity and resistivity, thereby inducing phase change under the action of the electric field, and miniaturizing the device through the application of micro-nano technology.

[0072] Phase change materials can also be directly used to make a temperature control layer to achieve heating and cooling effects.

[0073] The laser distance measuring device is composed of a laser transmitter, a laser receiver and a time-of-flight calculator;

[0074] The laser time-of-flight method measures the distance between the target and the sensor through the flight time of the light pulse. The time when the injection needle contacts the skin is set to zero. As the depth of the needle penetration increases, the flight time of the light pulse decreases, and the accurate depth of the injection needle in the body can be calculated.

[0075] The laser emitter is a light source that generates and emits a short pulse light beam, and the pulse light beam is aimed at the target surface;

[0076] The laser receiver receives the pulse light beam reflected from the target surface;

[0077] The time-of-flight calculator uses the flight time (t) of light and the known light speed (c) to calculate the distance between the target surface and the receiver (the tail end of the injection needle). The insertion depth (D) is calculated based on the length (L) of the injection needle, as Figure 2 As shown, the calculation formula is:

[0078] D = L - (c x t) / 2.

[0079] The injection needle 14 is mounted on the base of the solenoid valve to maintain a sealed state to ensure that the medical treatment substance does not leak, and the needle can be flexibly replaced, and the model, size and shape of the needle are not limited;

[0080] The solenoid valve 15 is located between the injection needle and the material transport pipe, and the opening speed and duration of the solenoid valve are adjusted by the intelligent center to effectively control the injection speed and dosage of the medical treatment substance;

[0081] A miniature remote sensing pressure sensor 18 in the front chamber 4 collects the internal pressure information of the front chamber and sends it to the intelligent center. The internal pressure of the front chamber is automatically adjusted according to the set conditions to ensure the accuracy of the injection dose and the safety of the injection site. For example, if an alarm occurs when the injection pressure is too low under the set conditions, it should be considered whether the implant directly enters the blood vessel or the interface leaks, and there is a potential risk of side effects; if an alarm occurs when the pressure is too high, there may be a blockage in the needle and pipeline, or other faults, reminding the operator to be alert.

[0082] A micro remote sensing pressure sensor 18 of the rear cabin 5 collects the internal pressure information of the rear cabin and sends it to the intelligent center, which automatically adjusts the internal pressure of the rear cabin according to the set conditions to ensure the effectiveness and safety of implant injection.

[0083] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
