[0025] The following will combine Figures 1 to 4 to describe the nuclear medicine medicine injection fume hood of the present application.

[0026] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the nuclear medicine medicine injection fume hood of the present application embodiment comprises: split instrument 1, activity meter 2, syringe 3 and shielding fume hood 4.

[0027] The shielded fume hood 4 is provided with oppositely arranged operation windows 41 and injection windows 44, the dispensing instrument 1, the activity meter 2 and the syringe 3 are all installed in the shielded fume hood 4, the dispensing instrument 1 is configured to dispense drugs and detect the activity through the activity meter 2, so that the dose of the drugs is the target dose, and the target dose of the drugs is delivered to the syringe 3.

[0028] The shell of the shielded fume hood 4 is a lead-coated stainless steel material, which is a composite material formed by wrapping a lead layer on a stainless steel substrate through a certain process. This material has the characteristics of corrosion resistance, high strength, easy processing of stainless steel, and high density, good shielding effect of lead.

[0029] In addition, the shielded fume hood 4 is provided with operation windows 41 and injection windows 44, wherein the number of operation windows 41 can be two, and the two operation windows 41 are arranged at intervals, and the number of injection windows 44 can be one. Exemplarily, the operation windows 41 and the injection windows 44 can both be through holes, or the operation windows 41 and the injection windows 44 include through holes and cover plates, and the cover plates can be covered on the through holes. When using the operation windows 41 and the injection windows 44, the cover plates can be away from the through holes.

[0030] In actual application, the dispensing instrument 1 configures the target dose of drugs according to user demand, and delivers the configured drugs to the syringe 3. At this time, the operator can put his hand through the operation window 41 into the shielded fume hood 4 to pick up the syringe 3, and at the same time, the patient's hand is placed near the injection window 44, so that the operator can inject the drugs in the syringe 3 into the patient's body. In the whole process, the patient and the operator are separated, and the operator does not need to contact the nuclear medicine, which improves the dispensing accuracy and efficiency while avoiding unnecessary radiation risk in the process.

[0031] As shown in Figure 1 , Figure 2 and Figure 4 , the shielded fume hood 4 is embedded in the wall 5, and the operation windows 41 and the injection windows 44 correspond to different areas respectively.

[0032] Specifically, the wall 5 is located between the operation room and the treatment room, the shielded fume hood 4 is embedded in the wall 5, and the operation windows 41 are exposed to the operation room and the injection windows 44 are exposed to the treatment room. That is to say, in the whole process, the patient and the operator can be separated.

[0033] As shown in Figure 1 , Figure 3 and Figure 4 , the shielded fume hood 4 is provided with a loudspeaker 45 on the side provided with the injection window 44, and the shielded fume hood 4 is provided with a microphone 43 on the side provided with the operation window 41.

[0034] The loudspeaker 45 is arranged on the side of the fume hood 4 where the injection window 44 is located. This arrangement can be used to provide necessary audio information or instructions to the patient during the experiment or operation process through the loudspeaker 45. For example, the loudspeaker 45 can be used to play guidance, alarm signals or other important notifications to ensure that the patient can obtain critical information in time. In addition, the microphone 43 is arranged on the side of the fume hood 4 where the operation window 41 is located. This arrangement facilitates the capture of voice instructions or feedback from the operator. The microphone 43 can be used to realize voice communication function, so that the operator can communicate with other personnel or systems through voice.

[0035] Therefore, the loudspeaker 45 and the microphone 43 are arranged on the specific side of the fume hood 4 to meet the audio information demand and voice communication demand during the operation process.

[0036] As shown in Figure 1 , Figure 2 and Figure 3 , the fume hood 4 is also provided with an observation window 42 on the side where the operation window 41 is located. The material of the observation window 42 should have good transparency and sufficient protection to ensure that the operator can clearly see the inside of the fume hood 4, while preventing harmful substances from leaking or external contamination.

[0037] In actual application, through the observation window 42, the operator can observe the progress of the operation without being exposed to the potentially dangerous environment, which helps to reduce the safety risk caused by direct contact with harmful substances or dangerous conditions. The operation window 41 is used for operation, while the observation window 42 provides real-time visual feedback of the operation process. In this way, the operator can perform the operation while monitoring the experimental progress through the observation window 42, thereby improving the accuracy and efficiency of the operation.

[0038] Therefore, the fume hood 4 is also provided with an observation window 42 on the side where the operation window 41 is located, which improves the convenience and safety of the operation process.

[0039] In an optional embodiment, as shown in Figure 2 , the fume hood 4 is internally installed with a lighting lamp 46. The switch of the lighting lamp 46 is installed on the side of the fume hood 4 where the operation window 41 is located. In this way, the operator can control the lighting lamp 46 conveniently. In addition, in the case that the operator inserts his hand through the operation window 41 into the fume hood 4 to pick up the syringe 3, the operator can turn on the lighting lamp 46 in advance, so that the operator can accurately and quickly inject the medicine in the syringe 3 into the patient's body.

[0040] As shown in Figure 1 , Figure 2 andFigure 3 As shown, the dispensing instrument 1 comprises a measuring bottle, a source liquid bottle, a physiological saline bottle, a liquid preparation device 11 and a control mainboard; the control mainboard is configured to drive the liquid preparation device 11 to draw source liquid in the source liquid bottle and physiological saline in the physiological saline bottle to the measuring bottle for mixing and activity measurement by the activity meter 2, and to draw the mixed liquid in the measuring bottle to the syringe 3.

[0041] The liquid preparation device 11 is electrically connected with the control mainboard, and the number of the liquid preparation device 11 can be multiple, for example, one liquid preparation device 11 is in fluid communication with the measuring bottle and the source liquid bottle, one liquid preparation device 11 is in fluid communication with the measuring bottle and the physiological saline bottle, and one liquid preparation device 11 is in fluid communication with the measuring bottle and the syringe 3. Exemplarily, the measuring bottle is connected to the inlet end of the liquid preparation device 11 through a first hose, and the barrel of the syringe 3 is connected to the outlet end of the liquid preparation device 11 through a second hose.

[0042] In actual application, the activity meter 2 is electrically connected with the control mainboard. In this way, the activity value obtained by the activity meter 2 can be sent to the control mainboard, and the control mainboard can compare the activity value with the target activity value to determine whether the activity value is equal to the target activity value. In the case that the activity value is less than the target activity value, the control mainboard controls the liquid preparation device 11 to perform corresponding actions until the activity value is equal to the target activity value.

[0043] In addition, the activity meter 2 is located below the dispensing instrument 1 and is correspondingly arranged with the measuring bottle. Exemplarily, the medicine dispensing fume hood is divided into three layers by two partitions, the upper layer is provided with the syringe 3, the middle layer is provided with the dispensing instrument 1, and the lower layer is provided with the activity meter 2. The partition between the middle layer and the lower layer is provided with an activity meter 2 hole to realize the contact between the activity meter 2 and the measuring bottle.

[0044] The activity meter 2 is an instrument for measuring the activity of radionuclides. It works based on the decay characteristics of radionuclides. When radionuclides decay, they release specific types of radiation, such as alpha particles, beta particles, gamma rays, etc. The activity meter 2 uses a detector (such as a Geiger-Muller tube) to capture and measure these radiations, and calculates the activity of the nuclide according to the measurement results. Specifically, each time a ray passes through the detector and causes ionization, the detector generates a detection current pulse, and each pulse is detected and recorded by the tube circuit as a count. The display value of the activity meter 2 is the count value in the selected mode. Due to the random nature of radioactivity, the count value detected by the dosimeter changes every minute, so the reading in a certain average time is usually taken as a more accurate measurement result.

[0045] In actual application, the medicine dispensing and injection fume hood further comprises a host computer, and the control mainboard is electrically connected with the host computer.

[0046] It should be noted that the host computer is the intelligent control center of the nuclear medicine medicine injection fume hood, which is responsible for receiving, processing and displaying data information from the control mainboard, and sending instructions to the control mainboard to realize remote control and monitoring of various functions of the fume hood. The host computer usually uses a high-performance computer or an embedded system, which has powerful data processing and storage capacity. Its interface is friendly and easy to operate, and can intuitively display the working state of the fume hood, the activity of radioactive drugs and other information.

[0047] The control mainboard is the "brain" of the nuclear medicine medicine injection fume hood, which is responsible for receiving instructions from the host computer and controlling various functions of the fume hood. The control mainboard usually uses a high-performance microprocessor or single-chip microcomputer as the core, which has the characteristics of high speed, stability and reliability.

[0048] For example, the host computer sends instructions to the control mainboard, and the control mainboard starts the liquid dispenser 11 to draw source liquid from the source liquid bottle and physiological saline from the physiological saline bottle to the measuring bottle. At the same time, the activity meter 2 is started to measure the activity to determine whether the activity of the mixed liquid in the measuring bottle is equal to the target activity, and finally the control liquid dispenser 11 draws the mixed liquid in the measuring bottle to the syringe 3.

[0049] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and are not limited thereto. Although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent substitutions for part of the technical features. These modifications or substitutions do not cause the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
