[0002] With the advancement of medical science and technology, radionuclides have been promoted and popularized in medical diagnosis and treatment techniques, especially in large and medium-sized hospitals, where their application is indispensable.

[0003] During the treatment process, it is often necessary to inject radioactive drugs into the patient's body for treatment. The rays released by radioactive drugs are penetrating. When they pass through the human body, they can ionize tissues and cause great harm. When injecting radioactive drugs into patients, in order to avoid radionuclide radiation to medical staff, a special radiation-proof injection window needs to be set up.

[0004] Medical staff observe and inject radioactive drugs into patients through the injection window. The glass of the injection window is tilted. Due to the different heights of medical staff, their arms are suspended in the air for injection. When injecting a large amount of drugs, wearing multiple layers of protective clothing increases the consumption of arm strength. Long-term use increases the intensity of work. At the same time, when many medical staff observe through the glass, their sight is deviated due to the refraction of the glass, which has an adverse effect on the injection work.

[0005] In order to solve the above problems, this application proposes a radiation protection injection device. Summary of the invention

[0023] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0024] like Figure 1-3 As shown, a radiation-proof injection device proposed by the present invention comprises a housing 1 and a radiation-proof window 2 arranged on the housing 1; the radiation-proof window 2 usually adopts special materials and structural designs to reduce the penetration of radiation. The following are two common radiation-proof window materials:

[0025] Lead glass: Lead glass is a transparent material that contains lead. Lead glass has a high density and radiation protection ability, and can effectively absorb and block radiation. It is often used in nuclear medicine and radiological diagnostic equipment, such as radiation-proof windows in X-ray rooms and nuclear medicine examination rooms.

[0026] Lead composites: Lead composites are made by combining lead shielding materials with other materials. Common composites include lead wire glass and lead-layered plastic. These composites maintain good radiation protection in structure and are relatively light and easy to manufacture. These radiation-proof window materials are widely used in nuclear medicine equipment and laboratories to effectively protect personnel from the hazards of radiation.

[0027] The housing 1 is provided with an operation opening for the hand to pass through, and the interior of the housing 1 is connected to a placement ring 4 for placing the hand through a suspension adjustment mechanism 3;

[0028] The shell 1 is made of lead material. The material of the bull head injection window in nuclear medicine usually uses lead or lead shielding material because lead has good radiation protection ability. Since the bull head injection window in nuclear medicine needs to block the radiation of radioactive substances, the lead material can effectively reduce the penetration of radiation and protect the safety of medical staff and patients. Lead can effectively absorb rays. By setting up a lead window, the radiation range of radioactive substances can be controlled and the radiation impact on the surrounding environment can be reduced. Lead is one of the common materials used for bull head injection windows in nuclear medicine.

[0029] A magnifying mechanism 5 for assisting viewing of the injection site is rotatably arranged on the placement ring 4 .

[0030] In an optional embodiment, the suspension adjustment mechanism 3 includes a mounting block 31, a sphere 32, a suspension rod 33, a spring 34 and a sleeve 35. The mounting block 31 is fixedly mounted inside the shell 1. The mounting block 31 is rotatably connected to the suspension rod 33 through the sphere 32. The sleeve 35 is fixedly mounted on the placement ring 4. The spring 34 is located inside the sleeve 35. One end of the spring 34 is fixedly connected to the inner wall of the sleeve 35, and the other end of the spring 34 is fixedly connected to one end of the suspension rod 33.

[0031] It should be noted that, under the action of the spring 34, the placement ring 4 automatically returns after moving.

[0032] In an optional embodiment, one end of the suspension rod 33 located inside the sleeve 35 is fixedly connected to a limiting rope, and one end of the limiting rope away from the suspension rod 33 is fixedly connected to the inside of the sleeve 35 .

[0033] It should be noted that the length of the limiting rope is the same as the length of the sleeve 35, so as to prevent the suspension rod 33 from moving out of the sleeve 35, thereby increasing the stability of use.

[0034] In an optional embodiment, the inner circumference of the placement ring 4 is rotatably sleeved with balls 6 .

[0035] It should be noted that there are multiple balls 6 , and the balls 6 are evenly distributed with equal intervals between adjacent balls.

[0036] Under the action of the ball 6, the smoothness of the movement of the hand inside the placement ring 4 is increased.

[0037] In an optional embodiment, the magnifying mechanism 5 includes a rotating ball 51, a connecting rod 52 and a magnifying glass 53. The rotating ball 51 is rotatably sleeved inside the placing ring 4, one end of the connecting rod 52 is fixedly connected to the rotating ball 51, and the other end of the connecting rod 52 is fixedly connected to the magnifying glass 53.

[0038] It should be noted that the center of the rotating ball 51 is located inside the placement ring 4. Under the action of the rotating ball 51, the use angle of the magnifying glass 53 can be adjusted at multiple angles.

[0039] Furthermore, the connecting rod 52 is a flexible connecting rod.

[0040] In an optional embodiment, the connecting rod 52 is a gooseneck rod.

[0041] A gooseneck pole is a curved metal pole that is shaped like a gooseneck, hence the name. It is usually made of flexible and bendable metal materials (such as aluminum alloy or steel) and can be twisted or bent into various shapes and angles. The gooseneck pole has good flexibility and adjustability, and can support or suspend objects in different directions and angles. The gooseneck pole is designed to be flexible and can be bent or rotated as needed to adjust the direction and angle. It also has high stability and load-bearing capacity, and can support and fix relatively heavy objects.

[0042] It should be noted that, under the action of the gooseneck rod, it is convenient to bend and restore so as to adjust the position of the magnifying glass 53.

[0043] Furthermore, a base is provided at the bottom of the shell 1, and rollers are provided at the bottom of the base to facilitate the movement of the entire shell 1 to a desired position, thereby increasing convenience and flexibility of use.

[0044] In the present invention, the hand passes through the placement ring 4 and acts on the placement ring 4 according to the height and angle of use. The use of the spring 34 is conducive to changing the length value of the suspension rod 33 located inside the sleeve 35. Under the action of the sphere 32, the use angle of the placement ring 4 is adjusted to increase the flexibility and operability of use, and also plays an auxiliary support role for the hand; by moving the magnifying glass 53, under the action of the rotating ball 51, the use angle and position of the magnifying glass 53 can be adjusted, thereby assisting medical staff to observe the injection site through the radiation protection window 2, so as to improve the applicability of this device to different personnel and further improve the convenience and flexibility of the entire device.
