Description

Technical Field

[0001] This invention relates to the field of aseptic operating devices, and more particularly to a continuous bag dispensing device and isolator. Background Technology

[0002] Isolators are used in the aseptic production of products and require the creation of a sterile environment isolated from the outside world. To allow replaced filter cartridges or waste generated during operation to exit the isolator without disrupting its sealed environment, a continuous bag discharge device is typically installed at the isolator's outlet.

[0003] Currently, continuous bag dispensing devices typically have either a protrusion or a groove in the center of the lid for easy removal. A protrusion hinders the movement of objects inside the isolator and the operational process; a groove, on the other hand, leads to water accumulation after cleaning the isolator, which can easily breed bacteria and disrupt the sterile environment inside the isolator.

[0004] Therefore, there is an urgent need to provide a continuous bag dispensing device and an isolator to solve the above problems. Summary of the Invention

[0005] One object of the present invention is to provide a continuous bag dispensing device, wherein the lid is easy to remove and does not hinder the movement of objects inside the cavity, nor does it cause water accumulation.

[0006] Another objective of this invention is to provide an isolator with an unobstructed operating space inside the isolator body, which is easy to clean and does not accumulate water.

[0007] To achieve the above objectives, the following technical solution is provided:

[0008] A continuous bag discharge device for the safe discharge of waste from inside a separator, comprising:

[0009] A continuous bag outlet, wherein the continuous bag outlet has a through inlet and an outlet;

[0010] The cover includes a first end face and a second end face that are disposed opposite to each other, wherein the first end face is capable of sealing and covering the inlet.

[0011] The handle is magnetically attached to the second end face.

[0012] As an optional solution for the continuous bag dispensing device, the cover is provided with a first magnetic suction element and the handle is provided with a second magnetic suction element, and the first magnetic suction element and the second magnetic suction element can be magnetically attracted to each other.

[0013] As an alternative to the continuous bag dispensing device, the first end face is recessed with a first mounting groove, and the first magnetic suction member is disposed in the first mounting groove; and / or, one end face of the handle is recessed with a second mounting groove, and the second magnetic suction member is disposed in the second mounting groove.

[0014] As an alternative to the continuous bag dispensing device, an annular retaining ring is provided on the first end face of the cover, the annular retaining ring extends in a direction away from the second end face, and the annular retaining ring can be inserted into the inlet.

[0015] As an optional solution for the continuous bag dispensing device, the continuous bag dispensing device includes an air-tight assembly, which includes an air-tight ring and an air-tight mounting base. The air-tight mounting base is disposed at the inlet and connected to the continuous bag dispensing cylinder. The air-tight mounting base is recessed with an air-tight mounting groove, and the opening of the air-tight mounting groove corresponds to the annular retaining ring. The air-tight ring is installed in the air-tight mounting groove so that the air-tight ring can tighten the annular retaining ring.

[0016] As an optional solution for the continuous bag dispensing device, the side wall of the airtight mounting base is provided with an inflation hole in the radial direction, and the inflation nozzle of the airtight ring can pass through the inflation hole and be connected to the inflation device.

[0017] As an optional solution for the continuous bag dispensing device, the continuous bag dispensing cylinder includes a first cylinder and a second cylinder arranged sequentially along the axial direction. One end of the first cylinder is sealed with the cover, and the other end is detachably connected to the second cylinder.

[0018] As an alternative to the continuous bag dispensing device, the continuous bag dispensing device also includes a clamp, and the first cylinder and the second cylinder are connected by the clamp.

[0019] As an optional solution for the continuous bag dispensing device, the handle is provided with gripping grooves, and two gripping grooves are arranged opposite each other on both sides of the handle.

[0020] As an alternative to the isolator, a continuous bag dispensing device as mentioned above is included, which also includes a continuous bag and an isolator body. The outlet of the isolator body is sealed to the continuous bag dispensing device, and the continuous bag is fitted onto the outer wall of the continuous bag dispensing device.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The continuous bag dispensing device provided by this invention seals the first end face of the cover at the inlet of the continuous bag dispensing cylinder. The second end face of the cover can be magnetically attracted to the handle. There is no need to set protrusions or grooves on the second end face of the cover, which ensures that the second end face is flat and smooth. When cleaning the isolator, the handle can be separated from the cover. After cleaning, there is no water residue on the second end face of the cover, which helps to ensure that the isolator is in a sterile environment. At the same time, it can also prevent moving objects in the isolator cavity from colliding with the handle.

[0023] The isolator provided by this invention ensures the smoothness of the second end face by magnetically adsorbing the handle of the continuous bag dispensing device to the cover, preventing objects inside the cavity from colliding, facilitating cleaning without water accumulation, and avoiding the growth of bacteria inside the isolator.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] In this embodiment, the continuous bag dispensing device is connected to the isolator. The continuous bag is fitted on the outer wall of the continuous bag dispensing device. By operating the opening or closing of the cover 2, the isolator can be connected to or isolated from the interior of the continuous bag dispensing device.

[0044] The following combination Figures 1 to 4 The specific content of this embodiment has been described in detail. For example... Figure 1 and Figure 2 As shown, this embodiment provides a continuous bag discharge device for the safe discharge of waste inside an isolator. The continuous bag discharge device includes a continuous bag discharge cylinder 1, a cover 2, and a handle 3. The continuous bag discharge cylinder 1 is provided with an inlet 11 and an outlet 12 that are connected to each other. The cover 2 includes a first end face and a second end face that are arranged opposite to each other. The first end face of the cover 2 can seal the inlet 11, and the handle 3 can be magnetically attached to the second end face of the cover 2.

[0045] In summary, the continuous bag dispensing device provided by this invention seals the first end face of the cover 2 at the inlet 11 of the continuous bag dispensing cylinder 1, and the second end face of the cover 2 is magnetically attached to the handle 3. No protrusions or grooves are needed on the second end face of the cover 2, ensuring its smoothness and flatness. When cleaning the isolator, the handle 3 can be separated from the cover 2. After cleaning, there is no water residue or bacterial growth on the second end face of the cover 2, which helps ensure the isolator is in a sterile environment and also prevents objects inside the isolator from colliding with the handle 3.

[0046] Preferably, the height of the other end face of the cover 2 gradually decreases from the center to the outer edge of the cover 2, which further promotes the rapid sliding of water and ensures that the other end face of the cover 2 is clean and free of water.

[0047] Furthermore, the continuous bag dispensing device also includes a magnetic suction assembly 4, which includes a first magnetic suction element 41 and a second magnetic suction element 42. The first magnetic suction element 41 is provided on the cover 2, and the second magnetic suction element 42 is provided on the handle 3. The first magnetic suction element 41 and the second magnetic suction element 42 can magnetically attract each other, realizing the mutual attraction between the cover 2 and the handle 3. Specifically, when both the handle 3 and the cover 2 are made of plastic, the magnetic attraction between the handle 3 and the cover 2 is greater than the weight of the cover 2 itself. When cleaning the isolator cavity, the handle 3 is separated from the cover 2 by manually pressing down on the cover 2.

[0048] Furthermore, the first end face of the cover 2 is recessed with a first mounting groove 21, and the first magnetic member 41 is disposed in the first mounting groove 21; and / or the first end face of the handle 3 is recessed with a second mounting groove 31, and the second magnetic member 42 is disposed in the second mounting groove 31. This reduces the space occupied by the first magnetic member 41 and the second magnetic member 42, achieving concealed installation of the first magnetic member 41 on the cover 2 and the second magnetic member 42 on the handle 3. Specifically, the first end face of the cover 2 is recessed with two first mounting grooves 21, and the first end face of the handle 3 is recessed with two second mounting grooves 31. The first magnetic member 41 is adhered to the first mounting groove 21, and the second magnetic member 42 is screwed into the second mounting groove 31, achieving a stable connection and convenient replacement.

[0049] Furthermore, an annular retaining ring 22 is protruding from the first end face of the cover 2. The annular retaining ring 22 extends in a direction away from the second end face and can be inserted into the inlet 11. Optionally, as the annular retaining ring 22 extends in a direction away from the second end face, its outer diameter gradually increases, and multiple protrusions are added to the outer wall of the annular retaining ring 22 to increase the compressive force between the annular retaining ring 22 and the inlet 11, thereby improving the sealing performance of the continuous bag outlet device. The sum of the weight of the cover 2 itself and the compressive friction between the annular retaining ring 22 and the inlet 11 is less than the magnetic attraction between the handle 3 and the cover 2. When cleaning the isolator cavity, the handle 3 is separated from the cover 2 by manually pressing down on it.

[0050] Furthermore, such as Figure 3 and Figure 4As shown, the continuous bag dispensing device includes an airtight assembly 5, which includes an airtight ring 51 and an airtight mounting base 52. The airtight mounting base 52 is located at the inlet 11 and connected to the continuous bag dispensing cylinder 1. The airtight mounting base 52 has a recessed airtight mounting groove, and the opening of the groove corresponds to the annular retaining ring 22. The airtight ring 51 is installed in the airtight mounting groove so that the airtight ring 51 can tighten the annular retaining ring 22. When the annular retaining ring 22 is engaged at the inlet 11, the airtight ring 51 located in the airtight mounting base 52 is inflated, tightening the annular retaining ring 22, achieving a double seal between the cover 2 and the continuous bag dispensing cylinder 1, further improving the sealing performance of the continuous bag dispensing device. The sum of the weight of the cover 2 itself, the compressive friction between the annular retaining ring 22 and the inlet 11, and the tightening friction of the airtight ring 51 on the annular retaining ring 22 is greater than the magnetic attraction between the handle 3 and the cover 2. When cleaning the isolator cavity, simply inflate the airtight ring 51 to tighten the annular retaining ring 22, ensuring a tight seal and preventing water leakage. Lifting the handle 3 allows for easy separation from the cover 2 without manual assistance. When discharging waste, venting the airtight ring 51 releases the air and loosens the annular retaining ring 22, allowing for quick and easy release of the cover. In this embodiment, the cross-section of the airtight mounting groove is rectangular, which facilitates both the fabrication of the groove and the storage of the airtight ring 51 within it.

[0051] Furthermore, the side wall of the airtight mounting base 52 is provided with an inflation hole 521 extending radially, through which the inflation nozzle of the airtight ring 51 can pass and connect to the inflation device. By controlling the on / off button of the inflation device, the tightening or loosening of the airtight ring 51 can be controlled, thereby controlling the suction between the cover 2 and the handle 3.

[0052] In conventional continuous bag dispensing devices, the continuous bag dispensing cylinder 1 is fixedly connected to the side wall of the isolator cavity. When it is necessary to replace the continuous bag dispensing cylinder 1 with a different diameter model, the entire continuous bag dispensing device needs to be disassembled, which is time-consuming and labor-intensive.

[0053] Furthermore, the continuous bag outlet 1 includes a first cylinder 13 and a second cylinder 14 arranged sequentially along the axial direction. One end of the first cylinder 13 is sealed with a cover 2 and fixedly connected to the isolator cavity. The other end of the first cylinder 13 is detachably connected to the second cylinder 14. It is not necessary to disassemble the entire continuous bag outlet 1; only the second cylinder 14 of a different model needs to be replaced.

[0054] In other embodiments, the end plane of the inlet 11 of the first cylinder 13 is flush with the side wall of the isolator cavity, and the annular edge of the cover 2, which extends radially relative to the annular retaining ring 22, abuts against the side wall of the isolator cavity, improving the sealing performance of the continuous bag discharge device and further preventing sewage from flowing into the continuous bag discharge cylinder 1 when cleaning the isolator. Optionally, a waterproof sealing ring is added between the annular edge and the side wall of the isolator cavity to further improve the sealing performance of the continuous bag discharge device.

[0055] Furthermore, the continuous bag dispensing device includes a clamp 6. The first cylinder 13 and the second cylinder 14 are sealed together using the clamp 6. The clamp 6 is a standard, readily available part, making it convenient, low-cost, and easy to replace if damaged. Preferably, the continuous bag dispensing device also includes a connecting assembly, which includes a flat connector and a washer. The connecting assembly, in conjunction with the clamp 6, further improves the sealing performance of the connection between the first cylinder 13 and the second cylinder 14. In this embodiment, the continuous bag dispensing device is divided into two parts connected by the clamp 6, allowing for quick and easy replacement of the lower bag dispensing section structure. It has a wide range of applications, is suitable for many scenarios, and is convenient and quick to use.

[0056] Furthermore, the handle 3 is provided with gripping grooves 32, with two gripping grooves 32 positioned opposite each other on both sides of the handle 3, making it convenient for the operator to pick up the handle 3. When it is necessary to open the cover 2, the handle 3 can be magnetically attached to the other end face of the cover 2. Even further, the handle 3 is provided with a hooking hole, which extends along the thickness direction of the handle 3. When cleaning the isolator cavity, the handle 3 is separated from the cover 2, and the handle 3 can be hooked onto the hook on the side wall of the isolator cavity through the hooking hole, facilitating the storage and placement of the handle 3.

[0057] This embodiment also provides an isolator, which includes the aforementioned continuous bag dispensing device, a continuous bag 7, and an isolator body 8. The outlet of the isolator body 8 is sealed to the continuous bag dispensing device, and the continuous bag 7 can be fitted onto the outer wall of the continuous bag dispensing device. Optionally, a first sealing ring 141 and a second sealing ring 142 are spaced apart on the outer wall of the second cylinder 14, so that the portion of the continuous bag 7 located in the second cylinder 14 is securely fitted onto the outer wall of the second cylinder 14.

[0058] Specifically, a first sealing ring 141 is fitted onto the upper part of the second cylindrical body 14, and two second sealing rings 142 are fitted onto the lower part of the second cylindrical body 14. Furthermore, an annular groove is provided at the connection between the second cylindrical body 14 and the first sealing ring 141 and the second sealing ring 142. The shape of the annular groove is adapted to the shape of the first sealing ring 141 and the second sealing ring 142, so that the continuous bag 7 is more securely fitted onto the second cylindrical body 14.

[0059] How to use the continuous bag dispensing device: When waste needs to be disposed of, the airtight ring 51 is depressurized. Using the attraction force of the second magnetic element 42 on the handle 3 on the first magnetic element 41 on the cover 2, the handle 3 is lifted to make the cover 2 detach from the airtight opening. The waste is then put into the continuous bag 7 with one end tied through the inlet 11. The sealed waste can be transferred for purification treatment. The remaining continuous bag 7 can be used for the next time.

[0060] Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
