[0036] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0037] Referring to Figure 1 and Figure 2 As shown, the cache device 1000 of the embodiment of the present utility model includes a first cache platform 100, a second cache platform 200, a lifting platform 300, a lifting mechanism 400 and a sensor. The lifting platform 300 is located on one side of the first cache platform 100 along the length direction. The second cache platform 200 is located below the first cache platform 100. The lifting platform 300 is disposed between the first cache platform 100 and the second cache platform 200 in a liftable manner. The lifting mechanism 400 is used to drive the lifting platform 300 to perform a lifting movement, so that the lifting platform 300 can move to the position of the first cache platform 100 or the second cache platform 200. The sensor is disposed on the lifting platform 300, and the sensor is used to sense whether there is a material on the lifting platform 300. The material may be a centrifuge cup. The first cache platform 100, the second cache platform 200 and the lifting platform 300 are all provided with a transport mechanism 500, and the transport mechanism 500 is used to transport the material on its corresponding platform along the length direction. It should be noted that the above length direction is Figure 1 the front-back direction inFigure 1 the front-back direction therein

[0038] When it is necessary to cache the centrifuge cups, the lifting mechanism 400 drives the lifting platform 300 to rise and makes the lifting platform 300 dock with the first caching platform 100. The centrifuge cups to be stored are placed on the first caching platform 100. The transporting mechanism 500 of the first caching platform 100 can transport the centrifuge cups on the first caching platform 100 to the lifting platform 300. The transporting mechanism 500 of the lifting platform 300 can receive the centrifuge cups on the first caching platform 100. Then, when the sensor senses the centrifuge cups, it indicates that the centrifuge cups are transported in place. At this time, the lifting mechanism 400 drives the lifting platform 300 to descend and makes the lifting platform 300 dock with the second caching platform 200. The transporting mechanism 500 of the lifting platform 300 transports the centrifuge cups on the lifting platform 300 to the second caching platform 200. The transporting mechanism 500 of the second caching platform 200 can receive the centrifuge cups on the lifting platform 300, so as to temporarily store the centrifuge cups on the second caching platform 200. Both the first caching platform 100 and the second caching platform 200 have caching capabilities and can cache a certain number of centrifuge cups. The caching device 1000 in this embodiment realizes the automatic temporary storage function, eliminating the need for medical staff to manually store centrifuge cups, which can reduce labor costs and the storage operation is relatively convenient. In addition, when it is necessary to take out the centrifuge cups, the lifting mechanism 400 drives the lifting platform 300 to descend and makes the lifting platform 300 dock with the second caching platform 200. The transporting mechanism 500 of the second caching platform 200 transports the centrifuge cups on the second caching platform 200 to the lifting platform 300. When the sensor senses the centrifuge cups on the lifting platform 300, it indicates that the centrifuge cups are transported in place. At this time, the lifting mechanism 400 drives the lifting platform 300 to rise and makes the lifting platform 300 dock with the first caching platform 100. The transporting mechanism 500 of the lifting mechanism 400 transports the centrifuge cups to the first caching platform 100, thus realizing the automatic taking out of the centrifuge cups.

[0039] It can be understood that the above-mentioned materials are not limited to centrifuge cups. In some other embodiments, the caching device 1000 can also be used to temporarily store other medical items, such as blood bags.

[0040] In some embodiments, the number of the second caching platforms 200 can be multiple. The multiple second caching platforms 200 are arranged at intervals in the up-down direction. The multiple second caching platforms 200 are all located below the first caching platform 100. The multiple second caching platforms 200 can cache more centrifuge cups, and the lifting platform 300 can move up and down to the positions of the multiple second caching platforms 200.

[0041] Refer to Figure 5As shown, in some embodiments, the top of the lifting platform 300 is provided with a mounting hole 310. The sensor includes a first photoelectric sensor 600. The first photoelectric sensor 600 is installed in the mounting hole 310. The upper end of the first photoelectric sensor 600 can be substantially flush with the lifting platform 300, avoiding the upper end of the first photoelectric sensor 600 protruding out of the top of the lifting platform 300. The emitting end of the first photoelectric sensor 600 is arranged upward, which can reduce the occupied space of the first photoelectric sensor 600. When the centrifuge cup passes through the first photoelectric sensor 600, the first photoelectric sensor 600 can detect that the centrifuge cup is located above the lifting platform 300. In this embodiment, a photoelectric sensor is used to sense whether the centrifuge cup is transported in place, and the manufacturing cost is relatively low.

[0042] Referring to Figure 4 As shown, in some embodiments, taking the transport mechanism 500 of the lifting platform 300 as an example for illustration, the transport mechanism 500 includes a motor 540 and at least two sets of conveyor belt assemblies 510. The two sets of conveyor belt assemblies 510 are respectively arranged on both sides of the lifting platform 300 along the width direction. It should be noted that the width direction is Figure 4 the left-right direction in []. The conveyor belt assembly 510 includes a conveyor belt 520 and a conveyor belt pulley 530. The conveyor belt 520 is sleeved on the outer periphery of the conveyor belt pulley 530. The motor 540 is used to drive the conveyor belt pulley 530 to rotate. The centrifuge cup can be placed on the conveyor belt 520. When the conveyor belt pulley 530 rotates, it can drive the conveyor belt 520 to move, thereby driving the centrifuge cup to move, so as to realize the transportation of the centrifuge cup. The upper end surface of the conveyor belt 520 can be higher than the lifting platform 300, so that the centrifuge cup does not contact the lifting platform 300, but it is required that the distance between the centrifuge cup and the lifting platform 300 is relatively small to ensure that the first photoelectric sensor 600 on the lifting platform 300 can detect the centrifuge cup. Since the two sets of conveyor belt assemblies 510 are respectively located on both sides of the lifting platform 300, the conveyor belts 520 of the two sets of conveyor belt assemblies 510 can transport the same centrifuge cup, or centrifuge cups can be respectively placed on the conveyor belts 520 of the two sets of conveyor belt assemblies 510, that is, the conveyor belts 520 of the two sets of conveyor belt assemblies 510 respectively transport multiple centrifuge cups, which can increase the number of cached centrifuge cups and temporarily store more centrifuge cups. It should be noted that the transport mechanism 500 of the first buffer platform 100 and the transport mechanism 500 of the second buffer platform 200 can also be arranged with reference to the method of this embodiment.

[0043] Referring to Figure 1As shown, in some embodiments, a second photoelectric sensor 610 is provided at one end of the first buffer platform 100 close to the lifting platform 300. The installation method of the second photoelectric sensor 610 can refer to the installation method of the above-mentioned first photoelectric sensor 600. The second photoelectric sensor 610 is used to detect whether the centrifuge cup on the first buffer platform 100 is transported in place and can also play a protective role to prevent the centrifuge cup from falling. For example, when the second photoelectric sensor 610 detects that the centrifuge cup is transported in place, but the lifting platform 300 has not risen to the first buffer platform 100, the transport mechanism 500 of the first buffer platform 100 can be controlled to stop transporting the centrifuge cup. After waiting for the lifting platform 300 to rise in place, then start transporting the centrifuge cup, which can prevent the centrifuge cup on the first buffer platform 100 from falling directly downwards.

[0044] Referring to Figure 1 As shown, in some embodiments, for the transport mechanism 500 of the first buffer platform 100, blood bags can be placed on the conveyor belt 520 of one group of conveyor belt assemblies 510, and centrifuge cups can be placed on the conveyor belt 520 of the other group of conveyor belt assemblies 510. A third photoelectric sensor 620 is further provided on the lifting platform 300, and the third photoelectric sensor 620 is used to detect whether the blood bag is transported in place. A fourth photoelectric sensor 630 is further provided on the first buffer platform 100, and the fourth photoelectric sensor 630 is used to detect whether the blood bag is transported in place.

[0045] Specifically, referring to Figure 1 and Figure 2As shown in the figure, on the first buffer platform 100, the conveyor belt 520 on the left transports centrifuge cups, and the conveyor belt 520 on the right transports blood bags. When the centrifuge cup on the first buffer platform 100 reaches the position of the second photoelectric sensor 610, the second photoelectric sensor 610 detects that the centrifuge cup has been transported in place. When the blood bag on the first buffer platform 100 reaches the position of the fourth photoelectric sensor 630, the fourth photoelectric sensor 630 detects that the blood bag has been transported in place. At this time, if the lifting platform 300 has not risen in place, the transport mechanism 500 of the first buffer platform 100 is controlled to stop transporting the blood bag and the centrifuge cup, and wait until the lifting platform 300 rises in place before continuing to transport. The transport mechanism 500 of the lifting platform 300 can receive the blood bag and the centrifuge cup on the first buffer platform 100. The transport mechanism 500 of the lifting platform 300 transports the blood bag to the position of the third photoelectric sensor 620 and transports the centrifuge cup to the position of the first photoelectric sensor 600. When the third photoelectric sensor 620 determines that the blood bag has been transported in place and the first photoelectric sensor 600 determines that the centrifuge cup has been transported in place, the transport mechanism 500 of the lifting platform 300 stops transporting the blood bag and the centrifuge cup. Then, the medical staff can put the blood bag on the lifting platform 300 into the centrifuge cup on the lifting platform 300. At this time, the third photoelectric sensor 620 cannot detect the blood bag, indicating that the blood bag has been put into the centrifuge cup. Then, the lifting mechanism 400 drives the lifting platform 300 to descend to the second buffer platform 200. The transport mechanism 500 of the lifting mechanism 400 transports the centrifuge cup containing the blood bag to the second buffer platform 200 to complete automatic temporary storage. In some embodiments, for the transport mechanism 500, its two sets of conveyor belt assemblies 510 are synchronous belt assemblies, that is, the conveyor belts 520 of the two sets of conveyor belt assemblies 510 are synchronously transported and have the same movement speed, which can ensure synchronous transportation of centrifuge cups and blood bags.

[0046] It should be noted that since the photoelectric sensor emits a light spot, when the number of photoelectric sensors is large and they work simultaneously, multiple light spots have a great interference on the eyes and line of sight of medical staff. Based on this, in some embodiments, each of the photoelectric sensors in the above embodiments can be configured as a limited reflection type photoelectric sensor. Specifically, the emitting end and the receiving end of the limited reflection type photoelectric sensor are both on the same side. The emitting end emits a light signal, and the light signal is reflected when passing through the surface of the material. The receiving end can receive the reflected light signal, thereby detecting the position of the material. The limited reflection type photoelectric sensor can be understood as a photoelectric sensor without a light spot, and the intensity of the light spot it emits is weak, which can avoid disturbing the line of sight of medical staff.

[0047] Refer to Figure 3 and Figure 4As shown, in some embodiments, the sensor includes a load cell 700. The lifting mechanism 400 is located below the lifting platform 300. The load cell 700 is connected between the lifting mechanism 400 and the lifting platform 300. The load cell 700 is used to detect the weight of the lifting platform 300. When the centrifuge cup is transported onto the lifting platform 300, the load cell 700 can detect a change in the weight of the lifting platform 300, thereby determining that the centrifuge cup has been transported in place. At this time, the lifting mechanism 400 can be controlled to drive the lifting platform 300 to move. It should be noted that the load cell 700 occupies a relatively small installation space, which is convenient for adjustment and installation. The load cell 700 also does not emit a light spot, which can avoid disturbing the medical staff's line of sight.

[0048] In some embodiments, the load cell 700 includes a strain beam structure. The strain beam structure is connected to the bottom of the lifting platform 300. It can also be understood that the strain beam structure supports the lifting platform 300. The weight of the lifting platform 300 is related to the elastic deformation amount of the strain beam structure. When the weight of the lifting platform 300 changes, the elastic deformation amount of the strain beam structure also changes, resulting in a change in the resistance value inside the strain beam structure. By measuring the resistance value of the strain beam structure, the weight of the lifting platform 300 can be known.

[0049] Refer to Figure 4 As shown, in some embodiments, the conveyor belt assembly 510 includes a support frame 350. The support frame 350 extends in the front-rear direction. The support frame 350 is connected to the bottom of the lifting platform 300. The conveyor belt pulley 530 is rotatably connected to the support frame 350. The support frame 350 can enhance the structural strength of the conveyor belt assembly 510. Moreover, the load cell 700 extends in the left-right direction, such that the load cell 700 straddles two groups of conveyor belt assemblies 510. The support frames 350 of the two groups of conveyor belt assemblies 510 are mounted on the load cell 700, which can make the force on the load cell 700 more uniform, improve the detection accuracy, and also reduce the occupied space of the load cell 700 in the up-down direction.

[0050] In some embodiments, the lifting mechanism 400 may include a slide rail, a slider, and a driving device. The slide rail extends in the up-down direction. The slider is slidably connected to the slide rail. The slider is also connected to the lifting platform 300. When the sensor includes a load cell 700, the driving device can be a cylinder or a lead screw motor. The driving device is used to drive the slider to move up and down, thereby driving the lifting platform 300 to move up and down. Without limitation, the lifting mechanism 400 can also adopt other combinations to achieve the lifting motion function.

[0051] Refer to Figure 1 、 Figure 2 and Figure 5As shown, in some embodiments, the first buffer platform 100, the second buffer platform 200, and the lifting platform 300 are all provided with a first limiting baffle 320 and a second limiting baffle 330 extending along the length direction. The first limiting baffle 320 and the second limiting baffle 330 are oppositely arranged along the width direction. The first limiting baffle 320 and the second limiting baffle 330 can limit the centrifuge cup or blood bag to prevent the centrifuge cup or blood bag from falling in the left and right directions. Refer to Figure 5 As shown, in some embodiments, the first limiting baffle 320 and the second limiting baffle 330 can be L-shaped plate structures. The first limiting baffle 320 is connected to one group of conveyor belt assemblies 510, and the second limiting baffle 330 is connected to the other group of conveyor belt assemblies 510.

[0052] Refer to Figure 5 As shown, in some embodiments, the lifting platform 300 is provided with a third limiting baffle 340 extending along the width direction. The third limiting baffle 340 is located at one end of the lifting platform 300 away from the first buffer platform 100. The third limiting baffle 340 can limit the centrifuge cup or blood bag to prevent the centrifuge cup or blood bag from falling backward. Refer to Figure 5 As shown, in some embodiments, the third limiting baffle 340 is connected to the top of the lifting platform 300, and the third limiting baffle 340 is located between the two groups of conveyor belt assemblies 510.

[0053] Refer to Figure 2 As shown, in some embodiments, when the length of the buffer device 1000 is fixed, the length of the lifting platform 300 is respectively smaller than the lengths of the first buffer platform 100 and the second buffer platform 200. The lengths of the first buffer platform 100 and the second buffer platform 200 can be extended, so that the buffer device 1000 can buffer more centrifuge cups, and the occupied space of the buffer device 1000 is smaller.

[0054] The embodiment of the present invention further provides a material storage management system. The material storage management system includes the buffer device 1000 in the above embodiment, which has the function of automatically temporarily storing centrifuge cups, can reduce the labor cost, and moreover, the material storage management system can be applied in a blood collection station. It should be noted that the material storage management system can also be used to temporarily store other medical items, such as blood bags.
