Description

Technical Field

[0001] This utility model relates to the field of pharmacokinetic testing technology, and in particular to a cross-contamination prevention and ventilation structure for a pharmacokinetic metabolism cage. Background Technology

[0002] Pharmacokinetics, or pharmacodynamics for short, primarily studies the dynamic changes in how the body processes drugs. This includes the absorption, distribution, biochemical transformation, and excretion of drugs within the body, particularly the changes in blood drug concentration over time. Drug metabolism is related to factors such as age, sex, individual differences, and genetic factors.

[0003] A pharmacokinetic metabolic cage is an experimental device used to study the metabolic processes of drugs in living organisms. By simulating the environment inside a living organism, it helps researchers better understand the absorption, distribution, metabolism, and excretion of drugs in the body.

[0004] The ventilation structure of traditional pharmacokinetic metabolism cages is generally connected by a main pipe and branch pipes for each metabolism cage. During the ventilation process, the air exhausted from each metabolism cage is prone to cross-contamination, which affects the accuracy of experimental data.

[0005] Therefore, it is necessary to provide a cross-contamination prevention and ventilation structure for a pharmacokinetic metabolism cage to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a cross-contamination prevention ventilation structure for pharmacokinetics metabolism cages, solving the problem that cross-contamination of air can easily occur when multiple metabolism cages are ventilated through interconnected main pipes and branch pipes, affecting the accuracy of experimental data.

A first one-way valve is fixedly connected to one end of the back of each exhaust pipe. A solenoid valve is installed on the other end of each first one-way valve. A connecting pipe is installed on the other end of each solenoid valve. A filter assembly is installed on the top of the cage. An exhaust pipe is installed on the back of the filter assembly through a connecting pipe. An exhaust assembly is installed on the top of the cage.

[0009] Multiple sealed doors are rotatably connected to the front of the partition frame via a rotating structure. A disinfection lamp is installed on the back of each sealed door. A cabinet door is rotatably connected to the front of the cage, and an air inlet pipe is installed on the front of the cabinet door.

[0010] The partition rack divides the interior of the enclosure into multiple independent areas. Multiple exhaust pipes correspond to the multiple areas inside the enclosure. The other end of the connecting pipe is connected to the exhaust pipe. The inlet of the exhaust assembly is connected to the filter assembly. The sealing door seals the area separated by the partition rack. If necessary, a hole can be opened on the sealing door to allow air to enter. Since the air is discharged from the exhaust pipe, opening a hole on the sealing door will not cause cross-contamination of the air inside the different areas.

[0011] Preferably, a support frame is installed at the bottom of the cage, the support frame includes a base plate and an anti-slip pad, and a handle is installed on the front of each of the sealed doors; the anti-slip pad is located at the bottom of the base plate near the four corners and mainly serves to prevent slipping.

[0012] Preferably, a control box with a door is installed on one side of the cage, and an operation panel is installed on the other side of the cage via a mounting base; the operation panel can set the equipment operating parameters.

[0013] Preferably, a second one-way valve is installed at the other end of the air intake pipe, and a filter pipe is installed at the other end of the second one-way valve through a valve, and a filter structure is installed inside the filter pipe.

[0014] Preferably, the exhaust assembly includes a protective shell, an exhaust pipe, an exhaust component, and a mounting pipe, wherein the mounting pipe is used to connect the inlet of the exhaust component and the filter assembly; the exhaust component is a device that provides suction, such as a separate unit.

[0015] Preferably, the filter assembly includes a filter box and an interceptor component for filtering dust and odors; the top of the filter box is fitted with a lid.

[0016] Compared with related technologies, this utility model has the following beneficial effects:

[0017] To reduce cross-contamination during the ventilation process of metabolic cages and improve the accuracy of experimental data, this invention divides the interior of a large metabolic cage into multiple spaces using a partition frame. An exhaust pipe equipped with a first one-way valve is installed at each of the partitioned spaces on the back of the cage. The first one-way valve ensures that air can only exit through the exhaust pipe, preventing air from flowing back into the cage. Each first one-way valve is equipped with a solenoid valve at the other end, allowing precise control of the exhaust in the corresponding space. By connecting the exhaust pipe to the corresponding solenoid valve via a connecting pipe, multiple spaces can be ventilated simultaneously when the exhaust assembly provides suction. This design divides the interior of the metabolic cage into multiple independent ventilation zones, each corresponding to an experimental animal space with an independent air duct design. The precise control of the exhaust zone by the first one-way valve and solenoid valve avoids cross-contamination during the exhaust process of multiple metabolic cages, thus improving the accuracy of experimental data.

A cabinet door 5 is rotatably connected to the front of the cabinet 4. An air inlet pipe 21 is installed on the front of the cabinet door 5.

[0029] The partition frame 18 divides the interior of the cage 4 into multiple independent areas. Multiple exhaust pipes 13 correspond to multiple areas inside the cage 4. The other end of the connecting pipe 14 is connected to the exhaust pipe 15. The inlet of the exhaust assembly 8 is connected to the filter assembly 7. The sealing door 16 seals the areas separated by the partition frame 18 separately. If necessary, a hole can be opened on the sealing door 16 to facilitate air entry. Since the air is discharged from the exhaust pipe 13, the opening on the sealing door 16 will not cause cross-contamination of the air inside the different areas. The air inlet pipe 21 facilitates the entry of air into the interior of the cage 4. The disinfection lamp 17 can disinfect the areas separated inside the cage 4 when needed.

[0030] The bottom of the cage 4 is equipped with a support frame 1, which includes a base plate 101 and an anti-slip pad 102. Each sealed door 16 has a handle 20 installed on its front.

[0031] The anti-slip mat 102 is located at the bottom of the base plate 101 near the four corners and mainly serves to prevent slipping. The top of the base plate 101 is connected to the top of the cage 4, and the handle 20 makes it easy to open the sealed door 16.

When the exhaust assembly 8 provides suction, air can be exhausted from multiple spaces simultaneously. In actual use, the exhaust assembly 8 provides suction to exhaust air from multiple spaces within the cabinet 4. During this process, the first one-way valve 11, in conjunction with the solenoid valve 12, precisely controls which space is ventilated and prevents air backflow. The exhausted air is filtered by the filter assembly 7 before being discharged. During the exhaust process, the air inlet pipe 21 on the cabinet door 5 draws clean external air into the cabinet 4.
