Description

Technical Field

[0001] This invention relates to the field of monkey isolators, and more particularly to a split-type semi-open monkey isolator. Background Technology

[0002] Negative pressure monkey isolators are a type of isolation and rearing equipment for laboratory monkeys. They create an independent, clean, or biosafety microenvironment for these monkeys in scenarios such as infection experiments, quarantine, and SPF-grade rearing. When the door of the negative pressure monkey isolator is opened, the negative pressure system responds immediately, increasing the exhaust volume and supplying air at the door opening to create a high-speed inward airflow, preventing aerosols and droplets from spreading outward from the cage.

[0003] When the existing negative pressure monkey isolator discharges the exhaust gas from each cage through the exhaust pipe, the pipe resistance increases and the exhaust volume decreases as the distance between the cage and the exhaust fan increases. This results in uneven exhaust from each cage, requiring constant air volume valves or regulating valves on the branch pipes to forcibly create resistance and limit the near-end air volume. This leads to a complex exhaust pipe structure, and the pipe walls are prone to accumulating dust or hair carrying pathogens. Summary of the Invention

[0004] The purpose of this invention is to provide a split-type semi-open monkey isolator to solve the problems of existing monkey isolators where the exhaust duct requires adjustment of resistance distribution through a damper and where dust or hair easily accumulates on the duct wall.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a split-type semi-open monkey isolator, comprising:

[0006] The isolation chamber comprises several stacked compartments, with air supply and exhaust connections located at the rear of each compartment, and a door hinged to the front of each compartment.

[0007] The negative pressure unit includes a supply fan, a main supply air pipe, a high-efficiency supply air box, an exhaust fan, a main exhaust air pipe, and a high-efficiency exhaust air box. The supply fan is connected to the air inlet of the high-efficiency supply air box, the end of the main supply air pipe is connected to the air outlet of the high-efficiency supply air box, several supply air branch pipes are provided on the main supply air pipe, the supply air branch pipes are connected to the air supply connector, the exhaust fan is connected to the air outlet of the high-efficiency exhaust air box, and the end of the main exhaust air pipe is connected to the air inlet of the high-efficiency exhaust air box.

[0008] The monkey cage is placed inside the cavity of the cabin;

[0009] The exhaust main pipe is bent at the end away from the exhaust high-efficiency box to form an air collection section. The air collection section is parallel to the exhaust main pipe and has several exhaust branch pipes connected to the exhaust connector.

[0010] As a further description of the above technical solution:

[0011] The top of the cabin is equipped with an air intake channel, which is T-shaped. The air intake channel includes a longitudinal channel and a transverse channel located at the end of the longitudinal channel. The air supply connector is located at the end of the longitudinal channel. Several air outlets are provided on the top wall of the cabin cavity. The air outlets are waist-shaped holes and are connected to the transverse channel.

[0012] As a further description of the above technical solution:

[0013] The cabin cavity back panel is equipped with an exhaust vent, which is connected to an exhaust connector and contains a filter.

[0014] As a further description of the above technical solution:

[0015] Two parallel guide rods are installed on the cavity sidewall of the cabin. At both ends of the guide rods are bent rods that bend toward the cavity sidewall, and the ends of the bent rods are fixedly installed on the cavity sidewall.

[0016] As a further description of the above technical solution:

[0017] The monkey cage includes a cage body, a panel, a back panel, and handles. The bottom of the cage body is equipped with rollers. The panel is detachably installed on the front side of the cage body. The back panel is symmetrically arranged with handles on both sides. The back panel is slidably connected to the cage body. The handles are inserted through the front side frame of the cage body. The cage body is equipped with symmetrically arranged first press-type spring pins on both sides. The bottom of the pin core of the first press-type spring pin contacts the handle.

[0018] As a further description of the above technical solution:

[0019] The cage has symmetrically arranged second push-type spring pins on both sides, and the inner wall of the cabin has slots corresponding to the second push-type spring pins.

[0020] As a further description of the above technical solution:

[0021] The cage contains two parallel guide rods that pass through the back plate. Guide wheels are rotatably mounted on the back plate, and the wheel surface of the guide wheel has an annular groove. The guide rods contact the bottom surface of the annular groove.

[0022] As a further description of the above technical solution:

[0023] A differential pressure gauge is fixedly installed on the door panel.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In the negative pressure system of the monkey isolator of this invention, the exhaust pipe is bent to form an air collection section, which forces the airflow to take a longer route. The exhaust path of the chamber far from the negative pressure host is short, while the exhaust path of the chamber close to the negative pressure host is long. This makes the total resistance of the near and far paths tend to be consistent, resulting in passive flow equalization and more balanced exhaust of each chamber. At the same time, the airflow turbulence caused by the bend in the pipe is used to flush the inner wall of the pipe, preventing dust or hair carrying pathogens from depositing on the pipe wall. Furthermore, when disinfecting the pipe with disinfectant gas in the later stage, it increases the disturbance and residence time of the disinfectant gas, thereby improving the disinfection effect.

[0026] 2. In this invention, in the split-type semi-open monkey isolator, the monkey 3 inside the chamber can be moved out or put in. The back panel in the monkey cage used to drive the animals inside can be moved by pulling the handle, and the position of the handle is locked by the pin core of the first press-type spring pin, so that the monkey cage can be moved by using the handle.

[0027] 3. In this invention, in order to improve the locking effect of the handle, several grooves are arranged in a straight line on the handle. The bottom of the pin core of the first press-type spring pin is inserted into the groove. At the same time, the locking position of the handle and the back plate can be precisely set to avoid the back plate from sticking to the filter element, which would cause the filter element to be squeezed and damaged or contaminated. This effectively ensures the coarse filtration effect of the filter element and avoids the accumulation of dirt on the pipe wall of the exhaust pipe. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] Please see Figure 1-10 This invention provides a technical solution: a split-type semi-open monkey isolator, comprising:

[0046] The isolation chamber comprises several stacked compartments 1, with air supply and exhaust connectors located on the rear of each compartment 1, and a door panel 11 hinged to the front of each compartment 1.

[0047] The negative pressure unit 2 includes a supply fan 21, a main supply air pipe 22, a high-efficiency supply air box 23, an exhaust fan 24, a main exhaust air pipe 25, and a high-efficiency exhaust air box 26. The supply fan 21 is connected to the air inlet of the high-efficiency supply air box 23, the end of the main supply air pipe 22 is connected to the air outlet of the high-efficiency supply air box 23, and the main supply air pipe 22 is provided with several supply air branch pipes 221. The supply air branch pipes 221 are connected to the air supply connector, the exhaust fan 24 is connected to the air outlet of the high-efficiency exhaust air box 26, and the end of the main exhaust air pipe 25 is connected to the air inlet of the high-efficiency exhaust air box 26.

[0048] Monkey cage 3 is placed inside the cavity of cabin 1 to form a split semi-open monkey isolator;

[0049] Among them, the exhaust main pipe 25 is bent at the end away from the exhaust high-efficiency box 26 to form an air collection section 251. The air collection section 251 is parallel to the exhaust main pipe 25. Several exhaust branch pipes 252 are installed on the air collection section 251, and the exhaust branch pipes 252 are connected to the exhaust connector.

[0050] An exhaust vent is provided on the back panel of the cavity of chamber 1. The exhaust vent is connected to an exhaust connector, and a filter element 14 is installed inside the exhaust vent. The filter element 14 is preferably a stainless steel wire mesh filter, which is corrosion-resistant and disinfectant-resistant, and achieves coarse filtration.

[0051] The monkey cage 3 includes a cage body 31, a panel 32, a back panel 33, and handles 34. The bottom of the cage body 31 is provided with rollers. The panel 32 is detachably installed on the front side of the cage body 31. The back panel 33 is provided with symmetrically arranged handles 34 on both sides. The back panel 33 is slidably connected inside the cage body 31. The handles 34 are inserted through the front side frame of the cage body 31. The cage body 31 is provided with symmetrically arranged first press-type spring pins 35 on both sides. The bottom of the pin core of the first press-type spring pin 35 contacts the handles 34.

[0052] In the split-type semi-open monkey isolator, the monkey cage 3 inside the chamber 1 can be moved out or put in. The back panel 33 in the monkey cage 3 used to drive the animals in the cage can be moved by pulling the handle 34, and the position of the handle 34 is locked by the pin core of the first press-type spring pin 35, so that the monkey cage 3 can be moved by using the handle 34.

[0053] To improve the locking effect of the handle 34, several grooves are arranged in a straight line on the handle 34. The bottom of the pin core of the first press-type spring pin 35 is inserted into the groove. At the same time, the locking position of the handle 34 and the back plate 33 can be precisely set to prevent the back plate 33 from sticking to the filter element 14, which would cause the filter element 14 to be squeezed and damaged or contaminated. This effectively ensures the coarse filtration effect of the filter element 14 and prevents dirt from accumulating on the wall of the exhaust pipe.

[0054] The cage 31 has two parallel guide rods 311 inside, which pass through the back plate 33. Guide wheels 312 are rotatably mounted on the back plate 33, and the wheel surface of the guide wheels 312 is provided with annular grooves. The guide rods 311 contact the bottom surface of the annular grooves. The back plate 33 moves smoothly along the guide rods 311 via the guide wheels 312, which facilitates the reciprocating movement of the back plate 33 via the handle 34.

[0055] A differential pressure gauge 111 is fixedly installed on the door panel 11. The differential pressure gauge 111 displays the real-time internal air pressure inside the cabin 1, ensuring safety when the door panel 11 of the split semi-open monkey isolator is opened.

[0056] Working principle: In the negative pressure system of the monkey isolator, the exhaust pipe 25 is bent to form an air collection section 251, which forces the airflow to take a longer route. The exhaust path of the chamber 1 far away from the negative pressure host 2 is short, while the exhaust path of the chamber 1 close to the negative pressure host 2 is long. This makes the total resistance of the near and far paths tend to be consistent, resulting in passive flow equalization and more balanced exhaust of each chamber 1. At the same time, the airflow turbulence caused by the pipe bends flushes the inner wall of the pipe, preventing dust or hair carrying germs from accumulating on the pipe wall. Furthermore, when using disinfectant gas to disinfect the pipe later, it increases the disturbance and residence time of the disinfectant gas, thereby improving the disinfection effect.

[0057] Example 2

[0058] Based on the above embodiments, this embodiment further improves upon the following technical solutions: an air inlet channel 12 is provided on the top of the cabin 1. The air inlet channel 12 is T-shaped and includes a longitudinal channel 121 and a transverse channel 122 located at the end of the longitudinal channel 121. An air supply connector is located at the end of the longitudinal channel 121. Several air outlets 13 are provided on the top wall of the cavity of the cabin 1. The air outlets 13 are waist-shaped holes and are connected to the transverse channel 122.

[0059] The air outlet 13 outputs a thin, elongated airflow, achieving highly uniform and precisely controllable air delivery.

[0060] Example 3

[0061] Based on the above embodiments, this embodiment further improves upon the following technical solution: two parallel guide rods 15 are provided on the cavity sidewall of the cabin 1, and the two ends of the guide rods 15 are provided with bent rods that bend toward the cavity sidewall, and the ends of the bent rods are fixedly installed on the cavity sidewall.

[0062] The guide rod 15 separates the monkey cage 3 from the cavity side wall of the cabin 1, avoiding collision damage when the guide rod 15 is moved out of the cabin 1. At the same time, the bending rod at the end of the guide rod 15 is used to guide the cage 15 when it is in the cabin 1.

[0063] Example 4

[0064] Based on the above embodiments, this embodiment further improves upon the following technical solution: symmetrically arranged second press-type spring pins 36 are provided on both sides of the cage 31, and slots corresponding to the positions of the second press-type spring pins 36 are provided on the inner wall of the cabin.

[0065] By using the pin core of the second press-type spring pin 36 to engage with the slot on the inner wall of the chamber, the position of the monkey cage 3 inside the chamber of the split semi-open monkey isolator is effectively locked, preventing the monkey cage 3 from accidentally moving out of the chamber and avoiding the spread of aerosols and droplets inside the cage to the outside.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
