Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical preservation technology, and in particular to a pharmaceutical preservation constant temperature device. Background Technology

[0002] In the field of clinical trial drug preservation, temperature control devices are core equipment for ensuring stable drug quality, and their performance directly affects the reliability of trial results and the safety of subjects taking the medication.

[0003] In existing technologies, conventional drug preservation temperature control devices mostly adopt an integrated cavity design, where all internal compartments are directly connected to the external environment when the cabinet door is opened. The internal temperature of the temperature control device changes rapidly in a short period of time, such as the rapid escape of cold air and the intrusion of hot and humid air from the outside when the door is opened. On the one hand, this affects the preservation of drugs; on the other hand, it results in high energy consumption. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a constant temperature device for medicine preservation, which solves the problem in the prior art that when the cabinet door is opened, all the internal compartments of the device are directly connected to the external environment, and the internal temperature of the constant temperature device will change rapidly in a short period of time.

[0005] This utility model solves the above-mentioned technical problems through the following technical means:

[0006] A drug preservation temperature control device, comprising:

[0007] The cabinet has doors that can be opened and closed;

[0008] Multiple drawers are slidably disposed within the cabinet body. The multiple drawers are arranged sequentially along the height of the cabinet body, with adjacent drawers fitting together vertically. Each drawer has several through slots at its bottom to allow air circulation between adjacent drawers.

[0009] By setting up the above structure, multiple closely arranged drawers form an inner partition door. When the cabinet door is opened, it can effectively reduce the size of the area connecting the cabinet with the outside world. Only the drawer for taking out and putting in medicines is pulled out to connect with the outside world, which can effectively slow down the rapid changes in the internal temperature of the cabinet in a short period of time and maintain the stability of the microenvironment temperature of the medicines.

[0010] Furthermore, the drawer opening is provided with an adjustable blocking component and an opening component. The opening component is movably mounted on the drawer along the sliding direction of the drawer. One end of the adjustable blocking component is connected to the end of the drawer near the cabinet door, and the other end is connected to the opening component. The adjustable blocking component is used to block the drawer opening, and the opening component is used to provide an opening for taking out and putting in medicines.

[0011] By setting up the above structure, the drawer opening is partially blocked after the drawer is pulled out, and medicines are only taken out and put in through the opening component, which reduces the size of the area where the drawer is connected to the outside world and further maintains the temperature stability of the medicine's microenvironment.

[0012] Furthermore, the opening assembly includes a first horizontal bar and a second horizontal bar. The first horizontal bar is slidably installed on the drawer. One side of the first horizontal bar is fixedly connected to one end of an adjustable shielding assembly, and the other side is provided with a limiting assembly. Both ends of the second horizontal bar are fixedly connected to the cabinet body. The limiting assembly is used to limit the maximum distance between the first horizontal bar and the second horizontal bar, and a medicine dispensing opening is formed between the first horizontal bar and the second horizontal bar.

[0013] By setting the above structure, when the drawer is pulled out, after the distance between the first and second horizontal bars reaches the maximum position, the adjustable blocking component gradually unfolds to block the drawer opening as the drawer continues to be pulled out. During this process, the medicine dispensing port corresponds to different positions inside the drawer. When the drawer moves to the position where medicine needs to be taken out or put in, medicine can be taken out or put in through the medicine dispensing port without the need for manual operation of the adjustable blocking component.

[0014] Furthermore, both sides of the drawer opening are provided with sliding grooves, and a sliding rod is fixedly installed in the sliding groove. The limiting component includes a sleeve, which is slidably sleeved on the sliding rod. A through hole is opened on the second horizontal bar. One end of the sleeve is fixedly connected to the first horizontal bar, and the other end is slidably inserted into the through hole. A limiting head is fixedly installed at the end of the sleeve away from the first horizontal bar. The limiting head is used to limit the maximum distance between the first horizontal bar and the second horizontal bar.

[0015] By setting the above structure, when the first horizontal bar moves away from the second horizontal bar, the sleeve moves synchronously with the first horizontal bar until the limiting head at the end of the sleeve abuts against the second horizontal bar, preventing the first horizontal bar from continuing to move away from the second horizontal bar, thus limiting the maximum distance between the first and second horizontal bars.

[0016] Furthermore, both ends of the second horizontal bar are provided with elastic protrusions, and limit holes are opened on both sides of the inner wall of the cabinet. When the elastic protrusions are inserted into the limit holes, the second horizontal bar is fixedly connected to the cabinet.

[0017] By setting up the above structure, the second horizontal bar is fixedly connected to the cabinet. When disassembly is required, simply pull the drawer to make the elastic protrusion exit from the limiting hole.

[0018] Furthermore, friction pads are provided at the bottom of both ends of the first horizontal bar, and the friction pads are used to increase the friction between the first horizontal bar and the inner wall of the groove.

[0019] By setting the above structure, the friction between the first horizontal bar and the inner wall of the slide is increased, ensuring that when the drawer is pulled out, the first horizontal bar and the drawer can move outward synchronously. After the distance between the first horizontal bar and the second horizontal bar reaches the maximum position, the first horizontal bar and the drawer rub against each other, so that the adjustable cover component can unfold to cover the drawer.

[0020] Furthermore, the adjustable shielding component includes a transparent accordion panel, and the drawer has a first mounting groove. One end of the transparent accordion panel is fixedly installed in the first mounting groove, and the other end is fixedly connected to the opening component.

[0021] Furthermore, a second mounting groove is provided at the bottom of the drawer, and several through grooves are connected to the second mounting groove. A baffle is movably provided in the second mounting groove along the sliding direction of the drawer. Several through grooves are provided on the baffle, and the through grooves correspond one-to-one with the through grooves. A first limiting plate is provided at one end of the second mounting groove, and a second limiting plate is provided at the other end. When the baffle abuts against the first limiting plate, the through grooves are connected to the through grooves. When the baffle abuts against the second limiting plate, the through grooves are misaligned with the through grooves, and the baffle blocks the through grooves.

[0022] By designing the above structure, when the drawer is pulled out of the cabinet, several through-slots at the bottom of the drawer are blocked, reducing the area of ​​the drawer connected to the outside world and further maintaining the microenvironmental temperature stability of the medicine. Furthermore, the bottom baffle of the drawer fits snugly against the top of the adjacent lower drawer. When the drawer is pulled outwards, the friction between the baffle and the adjacent lower drawer causes the baffle to automatically abut against the second limiting plate, blocking several through-slots. When the bottom drawer is pushed back into the cabinet, the friction between the baffle and the adjacent lower drawer causes the baffle to automatically abut against the first limiting plate, connecting the through-slots with the connecting slots.

[0023] Furthermore, the cabinet is equipped with sealing plates at both the top and bottom ends. The top sealing plate is fitted with the top drawer, and the bottom sealing plate is fitted with the bottom drawer.

[0024] By setting up the above structure, on the one hand, the space between the top and bottom drawers and the cabinet can be concealed, reducing the size of the area where the cabinet connects with the outside world. On the other hand, the bottom cover fits snugly against the bottom drawer. When the bottom drawer is pulled out, the friction between the cover and the baffle causes the baffle to automatically abut against the second limiting plate. When the bottom drawer is pushed into the cabinet, the friction between the cover and the baffle causes the baffle to automatically abut against the first limiting plate.

[0025] The beneficial effects of this utility model are:

[0026] 1. This utility model sets up multiple drawers that fit together and through grooves inside the drawers. The multiple closely arranged drawers form an inner partition door. When the cabinet door is opened, it can effectively reduce the size of the area connected between the cabinet and the outside world. Only the drawer for taking out and putting in medicines is pulled out to connect with the outside world. This can effectively slow down the rapid changes in the internal temperature of the cabinet in a short period of time and maintain the stability of the microenvironment temperature of the medicines.

[0027] 2. By setting an adjustable blocking component and an opening component, the opening of the drawer is partially blocked after the drawer is pulled out, and medicines are only taken out and put in through the opening component, which reduces the size of the area of ​​the drawer connected to the outside world and further maintains the temperature stability of the medicine's microenvironment.

[0028] 3. By setting a first horizontal bar and a second horizontal bar, when the drawer is pulled out, after the distance between the first horizontal bar and the second horizontal bar reaches the maximum position, the adjustable blocking component gradually unfolds to block the drawer opening as the drawer continues to be pulled out. During this process, the medicine dispensing port corresponds to different positions inside the drawer. When the drawer moves to the position where medicine needs to be taken out or put in, medicine can be taken out or put in through the medicine dispensing port without manual operation of the adjustable blocking component.

[0029] 4. This utility model, by setting a baffle, blocks several through-slots at the bottom of the drawer when the drawer is pulled out of the cabinet, reducing the area of ​​the drawer connected to the outside world and further maintaining the microenvironmental temperature stability of the medicine. Furthermore, the baffle at the bottom of the drawer fits snugly against the top of the adjacent lower drawer. When the drawer is pulled outwards, the friction between the baffle and the adjacent lower drawer causes the baffle to automatically abut against the second limiting plate, blocking several through-slots. When the bottom drawer is pushed into the cabinet, the friction between the baffle and the adjacent lower drawer causes the baffle to automatically abut against the first limiting plate, connecting the through-slots with the connecting slots.

[0046] like Figures 1-7 As shown, the present invention provides a medicine preservation temperature control device, comprising:

[0047] Cabinet 1, with openable and closable cabinet doors 11;

[0048] Multiple drawers 2 are slidably installed inside the cabinet 1. In this embodiment, each drawer 2 has a guide rail groove on both sides, and the cabinet 1 has guide rails at the corresponding positions of the guide rail grooves. Through the cooperation of the guide rails and guide rail grooves, the drawers 2 are stably slidably installed inside the cabinet 1. The multiple drawers 2 are arranged sequentially along the height direction of the cabinet 1, with adjacent drawers 2 fitting together. Each drawer 2 has several through slots 21 at its bottom to allow air circulation between adjacent drawers 2. In use, the multiple closely arranged drawers 2 form an inner partition door. When the cabinet door 11 is opened, it can effectively reduce the size of the area connecting the cabinet 1 with the outside world. Only the drawer 2 for taking out and putting in medicines is pulled out to connect with the outside world, which can effectively slow down the rapid changes in the internal temperature of the cabinet 1 in a short time and maintain the stability of the microenvironment temperature of the medicines.

[0049] In this embodiment, drawer 2 is set as a transparent drawer 2 so that medical staff can observe the types and locations of medicines inside drawer 2.

[0050] In this embodiment, an adjustable blocking component 3 and an opening component 4 are provided at the opening of drawer 2. The opening component 4 is movably mounted on drawer 2 along the sliding direction of drawer 2. One end of the adjustable blocking component 3 is connected to the end of drawer 2 near the cabinet door 11, and the other end is connected to the opening component 4. The adjustable blocking component 3 is used to block the opening of drawer 2, and the opening component 4 is used to provide an opening for taking out and putting in medicines. After drawer 2 is pulled out, the opening of drawer 2 is partially blocked, and medicines are taken out and put in only through the opening component 4, reducing the size of the area of ​​drawer 2 connected to the outside world and further maintaining the temperature stability of the medicine's microenvironment.

[0051] In this embodiment, the opening component 4 includes a first horizontal bar 41 and a second horizontal bar 42. The first horizontal bar 41 is slidably mounted on the drawer 2. One side of the first horizontal bar 41 is fixedly connected to one end of the adjustable blocking component 3, and the other side is provided with a limiting component 5. Both ends of the second horizontal bar 42 are fixedly connected to the cabinet 1. The limiting component 5 is used to limit the maximum distance between the first horizontal bar 41 and the second horizontal bar 42, forming a medicine dispensing opening between the first horizontal bar 41 and the second horizontal bar 42. In some other embodiments, it may not be necessary to fix the second horizontal bar 42. In this embodiment, by fixing the second horizontal bar 42, when the drawer 2 is pulled out, after the distance between the first horizontal bar 41 and the second horizontal bar 42 reaches its maximum position, when the drawer 2 is pulled out further, the adjustable blocking component 3 gradually unfolds to block the opening of the drawer 2. During this process, the medicine dispensing opening corresponds to different positions inside the drawer 2. When the drawer 2 moves to the position where medicine needs to be taken out or put in, medicine can be taken out or put in through the medicine dispensing opening without the need for manual operation of the adjustable blocking component 3.

[0052] In this embodiment, both sides of the drawer 2 opening are provided with sliding grooves 22, and a sliding rod 23 is fixedly installed in the sliding grooves 22. The limiting component 5 includes a sleeve 51, which is slidably sleeved on the sliding rod 23. A through hole 421 is provided on the second horizontal bar 42. One end of the sleeve 51 is fixedly connected to the first horizontal bar 41, and the other end is slidably inserted into the through hole 421. A limiting head 52 is fixedly provided at the end of the sleeve 51 away from the first horizontal bar 41. The limiting head 52 is used to limit the maximum distance between the first horizontal bar 41 and the second horizontal bar 42. When the first horizontal bar 41 moves away from the second horizontal bar 42, the sleeve 51 moves synchronously with the first horizontal bar 41 until the limiting head 52 at the end of the sleeve 51 abuts against the second horizontal bar 42, preventing the first horizontal bar 41 from continuing to move away from the second horizontal bar 42, thereby limiting the maximum distance between the first horizontal bar 41 and the second horizontal bar 42. In some other embodiments, the limiting component 5 can also be set as a connecting rope.

[0053] In this embodiment, both ends of the second horizontal bar 42 are provided with elastic protrusions 422, and limit holes 12 are provided on both sides of the inner wall of the cabinet 1. When the elastic protrusions 422 are inserted into the limit holes 12, the second horizontal bar 42 is fixedly connected to the cabinet 1. In some other embodiments, the second horizontal bar 42 can also be directly fixed to the cabinet 1 with bolts. In this embodiment, the second horizontal bar 42 is fixedly connected to the cabinet 1 through the elastic protrusions 422 and the limit holes 12. When disassembly is required, simply pull the drawer 2 to make the elastic protrusions 422 exit from the limit holes 12.

[0054] In this embodiment, friction pads 411 are provided at the bottom of both ends of the first horizontal bar 41. The friction pads 411 are used to increase the friction between the first horizontal bar 41 and the inner wall of the slide groove 22. Increasing the friction between the first horizontal bar 41 and the inner wall of the slide groove 22 ensures that when the drawer 2 is pulled outward, the first horizontal bar 41 and the drawer 2 can move outward synchronously. After the distance between the first horizontal bar 41 and the second horizontal bar 42 reaches its maximum position, the first horizontal bar 41 and the drawer 2 rub against each other, so that the adjustable blocking component 3 can unfold to block the drawer 2.

[0055] It should be noted that the pulling force required to pull the elastic protrusion 422 out of the limiting hole 12 must be much greater than the pulling force that causes relative friction between the drawer 2 and the first horizontal bar 41, in order to avoid the second horizontal bar 42 from detaching from the cabinet 1 under non-active conditions.

[0056] In this embodiment, the adjustable shielding component 3 includes a transparent accordion panel 31. A first mounting groove 25 is provided on the drawer 2. One end of the transparent accordion panel 31 is fixedly installed in the first mounting groove 25, and the other end is fixedly connected to the opening component 4. In this embodiment, one end of the transparent accordion panel 31 is fixedly installed in the first mounting groove 25, and the other end is fixedly connected to the first horizontal bar 41 of the opening component 4. In other embodiments, the adjustable shielding component 3 may also be configured as a transparent film similar to a measuring tape.

[0057] In this embodiment, a second mounting groove 24 is provided at the bottom of the drawer 2, and several through grooves 21 communicate with the second mounting groove 24. A baffle 6 is movably provided in the second mounting groove 24 along the sliding direction of the drawer 2. In this embodiment, a rod is provided in the second mounting groove 24, and the baffle 6 is slidably mounted on the rod, so that the baffle 6 is slidably mounted in the second mounting groove 24. Several through grooves 61 are provided on the baffle 6, and the several through grooves 21 correspond one-to-one. A first limiting plate 241 is provided at one end of the second mounting groove 24, and a second limiting plate 242 is provided at the other end. When the baffle 6 abuts against the first limiting plate 241, the through grooves 21 communicate with the through grooves 61. When the baffle 6 abuts against the second limiting plate 242, the through grooves 21 and the through grooves 61 are misaligned, and the baffle 6 blocks the several through grooves 21. When drawer 2 is pulled out of cabinet 1, several through slots 21 at the bottom of drawer 2 are blocked, reducing the area of ​​drawer 2 connected to the outside world and further maintaining the temperature stability of the medicine's microenvironment. Furthermore, the baffle 6 at the bottom of drawer 2 fits against the top of the adjacent lower drawer 2. When drawer 2 is pulled outwards, the friction between the baffle 6 and the adjacent lower drawer 2 causes the baffle 6 to automatically abut against the second limiting plate 242, blocking several through slots 21. When the bottom drawer 2 is pushed into cabinet 1, the friction between the baffle 6 and the adjacent lower drawer 2 causes the baffle 6 to automatically abut against the first limiting plate 241, connecting the through slots 21 with the connecting slots 61.

[0058] In this embodiment, both the top and bottom ends of the cabinet 1 are provided with sealing plates 13. The top sealing plate 13 fits into the topmost drawer 2, and the bottom sealing plate 13 fits into the bottommost drawer 2. On the one hand, this can block the space between the top and bottom drawers 2 and the cabinet 1, reducing the size of the area where the cabinet 1 communicates with the outside world. On the other hand, the bottom sealing plate 13 fits into the bottommost drawer 2. When the bottom drawer 2 is pulled out, the friction between the baffle 6 and the sealing plate 13 causes the baffle 6 to automatically abut against the second limiting plate 242. When the bottom drawer 2 is pushed into the cabinet 1, the friction between the baffle 6 and the sealing plate 13 causes the baffle 6 to automatically abut against the first limiting plate 241.

[0059] In this embodiment, a power switching device is also provided on the top of the cabinet 1. When the mains power connected to the constant temperature device fails, the power switching device automatically controls the generator to work, providing power to the constant temperature device and maintaining the stability of the microenvironment temperature of the medicine, without the need for manual intervention to start the generator.

[0060] The working principle of this utility model is as follows:

[0061] When taking out or putting out medicines, open cabinet door 11 and pull out the drawer 2 corresponding to the medicines.

[0062] When drawer 2 is pulled out, if the distance between the first horizontal bar 41 and the second horizontal bar 42 has not reached its maximum position:

[0063] Drawer 2 moves the first horizontal bar 41, pulling the first horizontal bar 41 out of cabinet 1. Sleeve 51 moves synchronously with the first horizontal bar 41 until the limiting head 52 at the end of sleeve 51 abuts against the second horizontal bar 42, preventing the first horizontal bar 41 from moving further away from the second horizontal bar 42. At this time, the distance between the first horizontal bar 41 and the second horizontal bar 42 reaches its maximum position.

[0064] During this process, the friction between the baffle 6 and the adjacent lower drawer 2 causes the baffle 6 to automatically abut against the second limiting plate 242, and the baffle 6 blocks several through slots 21, reducing the size of the area where the drawer 2 connects with the outside world.

[0065] After the distance between the first horizontal bar 41 and the second horizontal bar 42 reaches its maximum position, when continuing to pull out drawer 2:

[0066] The first horizontal bar 41 rubs against the drawer 2, and the first horizontal bar 41 pulls the transparent accordion panel 31 to gradually unfold and cover the opening of the drawer 2. During this process, the medicine retrieval port corresponds to different positions inside the drawer 2. When the drawer 2 moves to the position where it needs to be retrieved or placed, the medicine can be retrieved or placed through the medicine retrieval port.

[0067] After taking out or putting in items, when pushing drawer 2 into cabinet 1:

[0068] The first horizontal bar 41 moves toward the second horizontal bar 42. When the first horizontal bar 41 comes into contact with the second horizontal bar 42, the first horizontal bar 41 rubs against the drawer 2. The drawer 2 forces the transparent accordion panel 31 to fold gradually until the drawer 2 is fully pushed into the cabinet 1.

[0069] During this process, the friction between the baffle 6 and the adjacent lower drawer 2 causes the baffle 6 to automatically abut against the first limiting plate 241, and the through groove 21 connects with the connecting groove 61.

[0070] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
