Description

Technical Field

[0001] The utility model relates to a sampling cabinet. Background Art

[0002] In medical examinations, samples (such as through sampling tubes or sampling racks) need to be stored in sampling cabinets at low temperatures. However, the sampling cabinets used in existing hospitals (see CN 218898882 U) only have a single placement chamber and are equipped with multi-layer trays for placing different types of sampling tubes (or sampling racks). However, when using the cabinets, it is found that when it is necessary to take out or put in a sampling tube (or sampling rack) on a certain layer, the placement chamber is completely open when the cabinet door is opened, which will cause a large amount of cold air to be lost. At the same time, a large amount of outdoor air with bacteria and viruses enters, affecting temperature stability and safety.

[0003] In addition, the sampling cabinets (or medical refrigerators) used in existing hospitals are not equipped with disinfection devices, which makes regular disinfection troublesome.

[0004] At present, refrigerators with ultraviolet disinfection devices are available on the market (see CN105202857A, CN2074893U, etc.), and the ultraviolet disinfection lamp is fixed on the inner wall of the refrigerator through a lamp holder. Since the ultraviolet disinfection lamp and the lamp holder are detachably connected and the circuit is connected, and since the working temperature in the refrigerator is relatively low, this ultraviolet disinfection device has the risk of leakage in a humid environment containing moisture, and the safety level is low. It is also inconvenient to wipe and clean the refrigerator, or disinfect it with alcohol. Utility Model Content

[0005] The utility model provides a sampling cabinet which can solve the problem in the prior art that when the cabinet is opened, the entire storage chamber is opened, which causes a large amount of cold air to be lost and a large amount of bacteria and viruses to enter, and the problem that the existing installation method of the ultraviolet disinfection device in the sampling cabinet (or medical refrigerator) with a relatively low temperature is unsafe to use.

[0006] To achieve the above-mentioned purpose, the utility model provides a sampling cabinet, including a cabinet body and a refrigeration system, characterized in that: the interior of the cabinet body is divided into two placement chambers by a partition; two cabinet doors for opening and closing the two placement chambers respectively are provided on the front side of the cabinet body; an ultraviolet disinfection device is also included; a transparent tube is provided on the partition; the rear end of the transparent tube is an open end and extends to the rear of the cabinet body; the ultraviolet disinfection device includes a lamp holder and an ultraviolet lamp tube; the ultraviolet lamp tube is inserted into the transparent tube.

[0007] By adopting the above technical solution, since the sampling cabinet has two independently working storage rooms and two cabinet doors of the two storage rooms with independently controlled switches, when it is necessary to take out or put in a sampling tube or a sampling rack in one of the storage rooms, only one corresponding cabinet door is opened, and the other cabinet door remains closed, so that the other storage room is not opened, the cold air in the other storage room will not be lost, and the outdoor air is prevented from entering, and there will be no interference with the sampling tube (or sampling rack) stored in the other storage room, thereby ensuring stable temperature and safer storage.

[0008] Secondly, the sampling cabinet is provided with an ultraviolet disinfection device, which can realize the disinfection of the inside of the cabinet and the disinfection is convenient.

[0009] In addition, this ultraviolet disinfection device adopts a different layout and installation setting than the conventional one, and its characteristics are as follows:

[0010] (i) Since a transparent tube is provided on the partition, and the ultraviolet lamp is inserted into the transparent tube, the ultraviolet light emitted by the ultraviolet lamp can be irradiated into the two placement chambers through the transparent tube at the same time, thereby achieving bilateral disinfection at the same time and having the advantages of high efficiency and energy saving;

[0011] (ii) Since the ultraviolet lamp is built into the transparent tube, it is safely enclosed and protected, and safely separated. The ultraviolet lamp will not come into contact with the air in the two placement rooms, nor will it come into contact with the water mist on the inner walls of the two placement rooms, thereby avoiding the risk of leakage, having a higher safety level, and extending the service life. At the same time, when the two placement rooms are wiped and cleaned, disinfected with alcohol, etc., the ultraviolet lamp will not be affected, and it is safer to use.

[0012] (iii) Since the rear end of the transparent tube is an open end and extends to the rear of the cabinet, the ultraviolet lamp of the ultraviolet disinfection device can be pulled out from the transparent tube backwards together with the lamp holder, and the ultraviolet lamp can be easily disassembled and replaced. The operation is also very safe. When disassembling and replacing, the two cabinet doors do not need to be opened, and the power can be kept on. The temperature of the two cabinets will not be affected and can be kept at a constant temperature.

[0013] Therefore, the technical solution overcomes the problem that the above-mentioned prior art is that the entire storage chamber is open when opened, causing a large amount of cold air loss and the entry of a large number of bacteria and viruses, and the problem that the existing installation method of the ultraviolet disinfection device in a sampling cabinet (or medical refrigerator) with a lower temperature is unsafe to use.

[0014] Furthermore, a plurality of the transparent tubes are arranged on the partition and are distributed in parallel and at intervals; a plurality of the ultraviolet lamp tubes are installed on the lamp holder; and the positions of the ultraviolet lamp tubes correspond to those of the transparent tubes one by one.

[0015] Preferably, a mounting hole is provided on the rear outer wall of the cabinet; the lamp holder is detachably fixedly mounted in the mounting hole.

[0016] Preferably, the transparent tube is made of glass.

[0017] Furthermore, a radial fit clearance between the outer wall of the ultraviolet lamp tube and the inner wall of the transparent tube is greater than 3 mm.

[0018] Furthermore, a sampling rack is placed in the placement room; the sampling rack is made of transparent material as a whole.

[0019] Furthermore, the sampling rack includes a transparent lower plate, a transparent middle plate and a transparent upper plate which are arranged in sequence from bottom to top; the transparent lower plate, the transparent middle plate and the transparent upper plate are fixed together by four transparent columns; a plurality of sampling tube middle holes are arranged on the transparent middle plate; a plurality of sampling tube upper holes are arranged on the transparent upper plate; the positions of the sampling tube middle holes and the sampling tube upper holes correspond one to one.

[0020] Furthermore, two extension parts are symmetrically provided at both ends of the transparent upper plate; and two holding holes are symmetrically provided on the two extension parts.

[0021] Preferably, the sockets on the sampling tubes are distributed in a rectangular array.

[0022] Beneficial effects of the utility model:

[0023] First, when the sampling tube or sampling rack in one of the storage rooms needs to be taken out or put in, the utility model only opens one corresponding cabinet door, while the other cabinet door remains closed. In this way, the other storage room is not opened, the cold air in the other storage room will not be lost, and the outdoor air is prevented from entering, and the sampling tube (or sampling rack) stored in the other storage room will not be disturbed, thereby ensuring stable temperature and safer storage;

[0024] Second, the utility model adopts a layout and installation arrangement different from the conventional one. By arranging a transparent tube on the partition, and inserting the ultraviolet lamp into the transparent tube, the ultraviolet light emitted by the ultraviolet lamp can be irradiated into two placement rooms at the same time through the transparent tube, so that bilateral disinfection can be achieved at the same time, and it has the advantages of high efficiency and energy saving.

[0025] Thirdly, in the utility model, since the ultraviolet lamp is built in the transparent tube, it is safely enclosed and protected, and safely separated. The ultraviolet lamp will not contact the air in the two placement rooms, nor will it contact the water mist on the walls of the two placement rooms, thereby avoiding the risk of leakage, having a higher safety level, and extending the service life. At the same time, when the two placement rooms are wiped and cleaned, or disinfected with alcohol, the ultraviolet lamp will not be affected, and it is safer to use.

[0026] Fourthly, in the utility model, since the rear end of the transparent tube is an open end and extends to the rear of the cabinet, and the lamp holder is detachably fixed to the outer wall of the rear side of the cabinet, when the lamp holder is disassembled, the ultraviolet lamp tube can be pulled out from the transparent tube backward together with the lamp holder, and the ultraviolet lamp tube can be easily disassembled and replaced, and the operation is also very safe. Moreover, when disassembling and replacing, the two cabinet doors do not need to be opened, and the power can be kept without being turned off. The temperature of the two placement rooms will not be affected and can be kept at a constant temperature.

[0027] Fifth, the ultraviolet disinfection device of the sampling cabinet of the utility model can simultaneously perform ultraviolet sterilization and disinfection on the two placement rooms in the cabinet, and the double-sided irradiation is more energy-saving; and the ultraviolet lamp tube is built into a transparent tube, which is not exposed and is safer, and is also convenient for later disassembly and replacement.

[0035] Embodiment 1: Figure 1-5 As shown, a sampling cabinet includes a cabinet body 1, a refrigeration system and an ultraviolet disinfection device 2.

[0036] Among them, the refrigeration system is used for cooling the inside of the cabinet 1, which can be sampled from the existing technology and does not belong to the innovation of the present invention, so it is not repeated.

[0037] The interior of the cabinet 1 is divided into two storage rooms 1-2 by a partition 1-1; two cabinet doors 1-3 for opening and closing the two storage rooms 1-2 are provided on the front side of the cabinet 1;

[0038] A transparent tube 3 is fixedly installed in the middle of the partition 1-1; the rear end of the transparent tube 3 is an open end and extends to the rear of the cabinet 1. Specifically, the shape of the transparent tube 3 is larger than the thickness of the partition 1-1, so that the left and right sides of the transparent tube 3 protrude from the left and right sides of the partition 1-1 and extend into the two placement chambers 1-2 respectively.

[0039] The ultraviolet disinfection device 2 comprises a lamp holder 2 - 1 and an ultraviolet lamp tube 2 - 2 ; the ultraviolet lamp tube 2 - 2 is inserted into the transparent tube 3 ; the lamp holder 2 - 1 is detachably fixed on the rear outer wall of the cabinet 1 .

[0042] The sampling cabinet of this embodiment has two independently working storage chambers 1-2 and two cabinet doors 1-3 of the two storage chambers 1-2 that are independently controlled to switch. When it is necessary to take out or put in a sampling tube or a sampling rack in one of the storage chambers 1-2, only one corresponding cabinet door 1-3 is opened, and the other cabinet door 1-3 remains closed, so that the other storage chamber 1-2 is not opened, the cold air in the other storage chamber 1-2 will not be lost, and the outdoor air is prevented from entering, and there will be no interference with the sampling tube or sampling rack stored in the other storage chamber 1-2, thereby ensuring stable temperature and safer storage.

[0043] Secondly, the sampling cabinet is provided with an ultraviolet disinfection device 2, which can realize the disinfection of the interior of the cabinet 1 and the disinfection is convenient.

[0044] In addition, the ultraviolet disinfection device 2 adopts a layout and installation arrangement different from the conventional one, and its characteristics are as follows:

[0045] First, since a transparent tube 3 is provided on the partition 1-1, and the ultraviolet lamp 2-2 is inserted into the transparent tube 3, the ultraviolet light emitted by the ultraviolet lamp 2-2 can be irradiated into the two placement chambers 1-2 at the same time through the transparent tube 3, so that bilateral disinfection can be achieved at the same time, which has the advantages of high efficiency and energy saving;

[0046] Second, since the ultraviolet lamp 2-2 is built in the transparent tube 3, it is safely enclosed and protected, and safely separated. The ultraviolet lamp 2-2 will not come into contact with the air in the two placement chambers 1-2, nor will it come into contact with the water mist on the inner walls of the two placement chambers 1-2, thereby avoiding the risk of leakage, having a higher safety level, and extending the service life. At the same time, when the two placement chambers 1-2 are wiped, cleaned, or disinfected with alcohol, the ultraviolet lamp 2-2 will not be affected, and it is safer to use.

[0047] Third, since the rear end of the transparent tube 3 is an open end and extends to the rear of the cabinet 1; and the lamp holder 2-1 is detachably fixed to the outer wall of the rear side of the cabinet 1; when the lamp holder 2-1 is disassembled, the ultraviolet lamp 2-2 can be pulled out from the transparent tube 3 backward as a whole together with the lamp holder 2-1, and then the ultraviolet lamp 2-2 can be easily disassembled and replaced, and the operation is also very safe. Moreover, when disassembling and replacing, the two cabinet doors do not need to be opened, and the power can be kept without being turned off. The temperature in the two placement chambers 1-2 will not be affected and can be kept at a constant temperature.

[0048] See also Figure 6-7 In this embodiment, two transparent tubes 3 are arranged on the partition 1-1 and are spaced apart and parallel to each other; two ultraviolet lamp tubes 2-2 are installed on the lamp holder 2-1; and the two ultraviolet lamp tubes 2-2 are respectively inserted into the two transparent tubes 3 to achieve one-to-one position correspondence (see Figure 5 ).

[0049] In this embodiment, the transparent tube 3 is made of glass.

[0050] In this embodiment, the radial fit clearance S between the ultraviolet lamp tubes 2-2 and the ultraviolet lamp tubes 2-2 is greater than 3 mm. In this embodiment, preferably, the clearance S is 5 mm.

[0051] When storing samples, a sampling rack 4 is placed in the placement chamber 1-2. Preferably, the sampling rack 4 is made of transparent material as a whole.

[0052] Embodiment 2: This embodiment is based on embodiment 1.

[0053] See also Figure 8-9In this embodiment, the sampling rack 4 includes a transparent lower plate 4-1, a transparent middle plate 4-2 and a transparent upper plate 4-3 which are arranged in sequence from bottom to top; the transparent lower plate 4-1, the transparent middle plate 4-2 and the transparent upper plate 4-3 are fixed together by four transparent columns 4-4; a plurality of sampling tube middle jacks 4-21 are arranged on the transparent middle plate 4-2; a plurality of sampling tube upper jacks 4-31 are arranged on the transparent upper plate 4-3; the positions of the sampling tube middle jacks 4-21 and the sampling tube upper jacks 4-31 correspond to each other. When in use, the sampled sampling tube 6 is inserted into the sampling tube upper jacks 4-31 and the sampling tube middle jacks 4-21 and then supported by the transparent lower plate 4-1. The sampling tube 6 is very stable and can be placed in batches. Then the sampling rack 4 is placed in the corresponding placement chamber 1-2 and the door is closed for refrigeration. The sampling rack 4 is transparent as a whole, which is convenient for observation. At the same time, it can be directly placed in the placement chamber 1-2 for disinfection when it is empty.

[0054] Furthermore, two extensions are symmetrically provided at both ends of the transparent upper plate 4-3; and two holding holes 4-32 are symmetrically provided on the two extensions. The two holding holes 4-32 can facilitate the holding of the sampling rack 4, avoid hand slipping and falling, save effort and make it safer to use.

[0055] Before starting the disinfection work of the ultraviolet disinfection device 2, the sampling rack 4 can be placed in the two placement rooms 1-2 in advance and then the door can be closed and the disinfection work can be started together; since the sampling rack 4 is made of transparent material as a whole, ultraviolet rays can pass through, and the two placement rooms 1-2 and the sampling rack 4 can be disinfected at the same time, which can achieve all-round disinfection.

[0056] In addition, if the sampling racks 4 are not placed in the two placement chambers 1 - 2 , the ultraviolet disinfection device 2 can also be directly started to disinfect the two placement chambers 1 - 2 simultaneously.

[0057] Example 3: See Figure 8-9 This embodiment is based on the first or second embodiment.
