[0002] In the medical field, high-pressure injectors are used as auxiliary equipment in radiological diagnosis and treatment systems. In clinical practice, they are used as auxiliary equipment for CT, X-ray machines or other diagnostic and treatment equipment, which can greatly improve the diagnosis rate. Medical high-pressure injectors are usually composed of an injection head bracket, a control screen and a manual switch. The injection head is a device that controls the injection of contrast agents or saline. It can be programmed to complete the actions of inhaling liquid, expelling air from the syringe and pipeline, and high-pressure injection. The injection head also has the function of prompting the current working status, such as preparation, fault prompt, injection status display, etc. The control screen is an interface for human-computer interaction. Its main functions are setting the injection program, controlling the injection process, real-time display of the progress of the injection work process, injection end report, and real-time pressure curve display of the injection process. Medical high-pressure injectors are mainly used for cardiovascular angiography, CT enhanced angiography scanning and MR enhanced scanning.

[0003] In the north in winter, the liquid in the high-pressure syringe may freeze, so it is necessary to use it under temperature-controlled conditions or in a heated room.

[0040] like Figure 1-6 As shown, a high-pressure syringe with heating and heat preservation function described in the present invention comprises a main unit 110, a support rod 120 and a chassis 130 connected in sequence from top to bottom, wherein the front end of the main unit 110 is a heating device 200. The heating device 200 is mainly divided into a heating mechanism 210 and a hinge mechanism 220, wherein the heating mechanism 210 comprises an upper shell 211 and a lower shell 212, and the middle of the upper shell 211 is two U-shaped grooves 213 with openings upward. The two sides of the syringe 300 are locked by locking marbles 214, so that the heating device 200 can be positioned and fixed at the required position. The upper shell 211 and the lower shell 212 are buckled together to form an inner cavity, and a heating element 215 is arranged under the U-shaped groove 213 in the inner cavity, and the upper end surface of the heating element 215 is in contact with the lower end surface of the U-shaped groove 213. The U-shaped grooves 213 on the left and right sides can hold two syringes at the same time, thereby improving the efficiency of heating and heat preservation of the syringe 300. The heating mechanism 210 wraps around the syringe 300, which can heat and keep the syringe liquid warm while facilitating the disassembly and assembly of the syringe, avoiding the disassembly and assembly method of the syringe interfering with the syringe. The heating element 215 can be a resistance heating element or a heating film for heating and heat preservation. The inner cavity is fixed with a control mainboard 233 electrically connected to the heating element 215, and the control mainboard 233 is placed in the middle of the heating mechanism 210 in a sheet shape.

[0041] The hinge mechanism 220 is placed below the heating mechanism 210, connecting the heating mechanism 210 and the support rod 120. The movable end of the hinge mechanism 220 is fixedly connected to the heating mechanism 210, and the fixed end is fixedly connected to the main unit 110. The hinge mechanism 220 includes a fixed end wire sheath 225, a fixed end rotating shaft component 224, a movable end rotating shaft component 222 and a movable end wire sheath 221; one end of the fixed end rotating shaft component 224 is fixedly installed at the front end of the main unit 110, and the other end is rotatably connected to the movable end rotating shaft component 222; one end of the movable end rotating shaft component 222 is fixedly installed at the bottom end of the heating mechanism 210, and the other end is rotatably connected to the fixed end rotating shaft component 224; the fixed end wire sheath 225 is installed on the outside of the fixed end rotating shaft component 224, and the movable end wire sheath 221 is installed on the outside of the movable end rotating shaft component 222. The detection hole 226 is an infrared auxiliary detection, located in the middle of the fixed end shaft component 224, and is used to detect whether the heating mechanism 210 is closed. When the heating mechanism 210 is closed, the slot of the heating mechanism 210 facing the host 110 is just stuck in the fixed end shaft component 224.

[0042] The damping module 223 is a damping turntable, which connects the fixed end and the moving end, and can enable the structure to rotate up and down. The up and down rotation can be suspended at any angle and will not rotate and fall due to its own gravity. This rotation method is more secure and safe. The inner cavity is also fixed with a sensor unit 234 that is electrically connected to the control motherboard 233. The sensor unit 234 is an angle detection sensor, which is used to detect the angle of the heating mechanism 210. When the angle is adjusted to the correct position, the syringe 300 can be better heated. The heating mechanism 210 is connected to the main unit 110 in a snap-on or hinged manner to facilitate heating. The details of each component in the heating device 200 are as follows Figure 6 shown.

[0043] When the heating mechanism 210 in the rotating heating device 200 is rotated, the sensor unit 234 may be a resistance heating element or a heating film. After sensing the syringe, the sensor unit 234 starts heating, otherwise the sensor unit 234 does not heat. This intelligent induction heating and heat preservation is very convenient and safe.

[0044] The support rod 120 is in the shape of a round rod, and serves as a connection between the main unit 110 and the chassis 130. A round handle is provided on the support rod 120 for easy movement; the chassis 130 has four universal wheels for easy movement and strong flexibility.

[0045] like Figure 7-12 As shown, the working principle of the high-pressure injector with heating and heat preservation function described in the present invention is as follows:

[0046] like Figure 7 As shown, the host 110 is facing the operator, and the horizontal heating device 200 is vertically downward through the hinge mechanism 220, which makes it convenient to put the syringe 300 into the host 110 later. Figure 8 for Figure 7 100 and a partial enlarged view of the heating device 200. Figure 8 As shown, the heating mechanism 210 is connected to the hinge mechanism 220, and the fixed end shaft component 224 faces the direction in which the syringe 300 is about to be placed into the main unit 110; the fixed end shaft component 224 is provided with a detection hole 226, and the detection hole 226 can be used to infraredly assist in detecting whether the heating mechanism 210 is in a horizontal position. As shown in FIG9, when the heating mechanism 210 is vertically downward, the syringe 300 is placed into the main unit 110 away from the opening of the U-shaped groove 213, and two syringes 300 can be placed at the same time to improve the efficiency of heating and heat preservation. Fig.10 As shown, the two syringes 300 have been placed in the main unit 110. The heating mechanism 210 is vertically downward, which is convenient for disassembling and assembling the syringes 300, and the syringes 300 will not interfere with the disassembly and assembly process. Fig.11 FIG. 2 is a partial enlarged view of the hinge mechanism 220 and 230. Fig.11As shown, the movable end waterproof connector 231 is set to prevent the liquid medicine in the syringe 300 from flowing to the control main board 233; the lower shell 212 protects the control main board 233 so that it will not malfunction and affect its use due to the liquid medicine in the syringe 300 soaking 333.

[0047] like Fig.12 As shown, when the heating mechanism 210 is swung to 90 degrees horizontally, the sensor unit 234 detects whether its angle is correct. When the angle is correct, after the detection hole 226 detects the heating mechanism 210 with infrared assistance, the heating mechanism 210 starts to work, and the heating element 215 automatically heats and keeps warm. The heating mechanism 210 wraps the syringe 300 to better heat and keep warm the syringe 300. When the syringe 300 needs to be taken out, the heating mechanism 210 is rotated to 90 degrees downward; finally, the syringe 300 is taken out, and the heating mechanism 210 returns to the horizontal position.

[0048] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
