Description

Technical Field

[0001] This utility model belongs to the field of high-pressure injector technology, specifically a medical benchtop high-pressure injector. Background Technology

[0002] High-pressure injectors, as auxiliary equipment in radiological diagnostic and treatment systems, have gradually gained clinical application with the development of technologies such as X-rays, rapid film changers, image intensifiers, and artificial contrast agents. The basic function of a high-pressure injector is to rapidly and accurately inject a sufficient amount of high-concentration X-ray contrast agent into the examination site within a certain time frame, either percutaneously through a blood vessel or through existing body orifices. This allows for diagnostic imaging and treatment of lesions.

[0003] For example, a medical high-pressure injector with a booster mechanism, disclosed in CN219290336U, includes a support plate. A connecting cylinder is fixedly connected to the top of the support plate, and a sliding rod is slidably connected inside the connecting cylinder. A limiting component is provided between the connecting cylinder and the sliding rod. An mounting plate is fixedly connected to the top of the sliding rod, and a limiting sleeve is fixedly connected to the top of the mounting plate. An injection syringe is detachably installed inside the limiting sleeve. A connecting tube is fixedly connected to one end of the injection syringe, and a disinfection component is provided on the outer surface of the connecting tube. In this invention, by setting a disinfection component, a first spring squeezes the liquid bladder through the connecting rod. The liquid bladder is squeezed and sprays the disinfectant inside through the delivery tube and the spray nozzle, thereby achieving automatic disinfection of the connecting tube, ensuring the hygiene of the connecting tube during use, and avoiding infection and harm to the patient caused by bacteria on the surface of the connecting tube.

[0004] After prolonged use, the injection syringe may leak, causing contrast fluid to drip onto the outer wall of the high-pressure injector, which is difficult to clean. To solve this problem, a medical benchtop high-pressure injector is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems by providing a medical benchtop high-pressure injector, comprising:

[0006] The injection head has two syringes inserted into one side.

[0007] The protective block is snapped to the side of the injection head near the injection syringe. A storage cavity is provided on the front side of the protective block, and a baffle is fixedly installed at the lower end of one side of the storage cavity. A connection hole adapted to the injection syringe is provided on the front side of the protective block.

[0008] With the above technical solution, when using a high-pressure injector, a protective block is first fitted onto the outer wall of the injection head. The connecting hole on the front side of the protective block is used to expose the injection syringe. If leakage occurs during the use of the high-pressure injector, the leaked contrast agent will enter the receiving cavity through the gap. The contrast agent is blocked by the baffle on the front side of the receiving cavity to prevent it from dripping. On the one hand, the contrast agent will not remain on the outer wall of the high-pressure injector, which would make it difficult to clean. On the other hand, it prevents the contrast agent from dripping onto the ground.

[0009] In a preferred embodiment, the injection head has a display screen and buttons on its upper surface.

[0010] The above technical solution allows for the control and observation of the high-pressure injector's operation via a display screen and buttons.

[0011] In a preferred embodiment, locking grooves are provided on both the left and right sides of the injection head, locking pins are threaded to both the left and right sides of the protective block, and a locking block is rotatably connected to one side of the locking pin.

[0012] With the above technical solution, when the protective block is fitted onto the outer wall of the injection head, the locking pin is rotated to move the locking block inward into the locking groove, thereby connecting the protective block with the injection head, which is convenient for installation and disassembly.

[0013] In a preferred embodiment, the outer wall of the locking pin is provided with friction texture.

[0014] The above technical solution facilitates the rotation of the locking pin by setting friction grooves.

[0015] In a preferred embodiment, the outer wall of the baffle is provided with a groove adapted to the injection syringe.

[0016] In a preferred embodiment, a drain hole is provided on one side of the outer wall of the baffle.

[0017] The above technical solution facilitates the discharge of contrast fluid by setting up a drainage hole.

[0018] In summary, due to the adoption of the above technical solutions, the beneficial effects of this utility model are: this utility model proposes a medical benchtop high-pressure injector.

[0019] When using a high-pressure injector, first place the protective block on the outer wall of the injection head. The connecting hole on the front of the protective block is used to expose the injection syringe. If leakage occurs during the use of the high-pressure injector, the leaked contrast agent will enter the receiving cavity through the gap. The baffle on the front of the receiving cavity will block the contrast agent and prevent it from dripping. On the one hand, the contrast agent will not remain on the outer wall of the high-pressure injector, which would make it difficult to clean. On the other hand, it will prevent the contrast agent from dripping onto the ground. Attached Figure Description

[0025] 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 in conjunction with the embodiments of this utility model. 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.

[0026] The following will combine Figure 1-4 A detailed description of a medical benchtop high-pressure injector according to an embodiment of the present invention is provided.

[0027] Example:

[0028] A medical benchtop high-pressure injector, comprising:

[0029] The injection head 1 has two syringes 14 inserted into one side. The upper surface of the injection head 1 is equipped with a display screen 11 and a button 12. The use of the high-pressure injector is controlled and observed through the display screen 11 and the button 12.

[0030] The protective block 2 is snapped onto the side of the injection head 1 near the injection syringe 14. The front side of the protective block 2 has a storage cavity 21, and a baffle 22 is fixedly installed on the lower end of one side of the storage cavity 21. The outer wall of the baffle 22 has a groove that matches the injection syringe 14. The front side of the protective block 2 has a connection hole 23 that matches the injection syringe 14. A drain hole 26 is provided on one side of the outer wall of the baffle 22. The drain hole 26 facilitates the discharge of contrast agent. When using the high-pressure injector, the protective block 2 is first fitted onto the outer wall of the injection head 1. The connection hole 23 on the front side of the protective block 2 is used to expose the injection syringe 14. If leakage occurs during the use of the high-pressure injector, the leaked contrast agent will enter the storage cavity 21 through the gap. The baffle 22 on the front side of the storage cavity 21 blocks the contrast agent and prevents it from dripping. On the one hand, the contrast agent will not remain on the outer wall of the high-pressure injector, which would make it difficult to clean. On the other hand, it prevents the contrast agent from dripping onto the ground.

[0031] The injection head 1 has locking grooves 13 on both the left and right sides, and the protective block 2 has locking pins 24 threaded on both the left and right sides. The outer wall of the locking pin 24 is provided with friction texture, which facilitates the rotation of the locking pin 24. A locking block 25 is rotatably connected to one side of the locking pin 24. When the protective block 2 is fitted onto the outer wall of the injection head 1, the locking pin 24 is rotated to move the locking block 25 inward into the locking groove 13, thereby connecting the protective block 2 to the injection head 1, which is convenient for installation and disassembly.

[0032] Working principle:

[0033] When using the high-pressure injector, first place the protective block 2 on the outer wall of the injection head 1. The connecting hole 23 on the front side of the protective block 2 is used to expose the injection syringe 14. If leakage occurs during the use of the high-pressure injector, the leaked contrast agent will enter the receiving cavity 21 through the gap. The baffle 22 on the front side of the receiving cavity 21 will block the contrast agent and prevent it from dripping. On the one hand, the contrast agent will not remain on the outer wall of the high-pressure injector, which would make it difficult to clean. On the other hand, it will prevent the contrast agent from dripping onto the ground.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
