Description

Technical Field

[0001] The invention relates to the technical field of blood sample storage, in particular to a temporary blood storage device for clinical medical testing. Background Art

[0002] With the continuous development of modern medicine, clinical medical tests play a vital role in disease diagnosis and treatment. As an important part of medical tests, blood tests are key means of diagnosing diseases, monitoring conditions and evaluating treatment effects. In the process of blood tests, the correct storage and management of blood samples are important factors to ensure the accuracy of test results.

[0003] A patent with publication number CN211224704U discloses a temporary sample storage device for blood testing, in which a rubber base with cushioning and shock-absorbing function is provided under the socket for placing the test tube, and a layer of rubber ring is fixed on the wall around the socket, which effectively avoids the breakage and vibration of the test tube when it is inserted, and the wear and breakage caused by the contact between the test tube and the socket.

[0004] However, the test tube is directly exposed to the air and is easily contaminated and damaged by the external environment. The blood inside the test tube is also directly affected by the temperature of the surrounding air, causing the blood inside the test tube to be at an unfavorable temperature.

[0005] The disclosure of the above background technology content is only used to assist in understanding the concept and technical solution of the present invention. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above content has been disclosed on the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of the present application. Summary of the invention

[0006] The present application provides a temporary blood storage device for clinical medical testing, which can improve the temporary storage quality of blood samples.

[0007] To achieve the above objectives, the present application discloses the following technical solutions:

[0008] A temporary blood storage device for clinical medical testing comprises a chassis, a plurality of placement boxes, a plurality of flip mechanisms and a refrigeration assembly, wherein each placement box is arranged on the chassis; the plurality of flip mechanisms are arranged in one-to-one correspondence with the plurality of placement boxes, and each flip mechanism is used to control the automatic opening and closing of the box cover of the corresponding placement box; and the refrigeration assembly is used to adjust the temperature of the internal space of each placement box.

[0009] In the embodiment of the present application, a relatively closed storage space is provided by multiple placement boxes. When a blood test tube is placed in the placement box, the closing state of the box cover is controlled by the flip mechanism, thereby achieving effective sealing of the blood test tube, preventing dust and pollutants in the air from contacting the blood test tube, and reducing the risk of contamination. At the same time, the design of the refrigeration component provides a constant low-temperature environment inside the placement box, so that the blood sample can be kept at a suitable storage temperature, avoiding the adverse effects of external temperature fluctuations on the quality of the blood sample. In summary, the temporary storage quality of the blood sample can be improved.

[0010] In some possible implementations, the placement box includes a first shell and a second shell, the first shell is sleeved on the outside of the second shell, the first shell includes a first side plate, the second shell includes a second side plate, the first side plate and the second side plate are arranged opposite to each other, and there is a gap between the first side plate and the second side plate to form a first accommodation space; there is a gap between the bottom plate of the first shell and the bottom plate of the second shell to form a second accommodation space, and the first accommodation space is connected to the second accommodation space;

[0011] The flip mechanism includes a first connecting rod, a first connecting ear, a second connecting rod, a third connecting rod, a second connecting ear, and a telescopic device; the first connecting rod and the first connecting ear are arranged in the second accommodating space, the first connecting ear is fixedly connected to the first shell, the first connecting rod includes a first connecting section and a second connecting section, the connection between the first connecting section and the second connecting section is rotatably connected to the first connecting ear, and the end of the first connecting section away from the second connecting section is higher than the connection between the first connecting section and the second connecting section; the telescopic rod of the telescopic device is fixedly connected to the end of the first connecting section away from the second connecting section; the end of the second connecting section away from the first connecting section is rotatably connected to one end of the second connecting rod, the second connecting rod is arranged in the first accommodating space, the extension direction of the second connecting rod is parallel to the central axis of the placement box, the other end of the second connecting rod extends out of the second accommodating space and is rotatably connected to one end of the two third connecting rods, the other ends of the two third connecting rods are rotatably connected to the second connecting ear, and the second connecting ear is fixedly connected to the box cover; the box cover is rotatably connected to the second shell.

[0012] In this way, when the telescopic device is extended or retracted, the first connecting rod rotates around the first connecting ear, thereby driving the second connecting rod connected thereto to move along the central axis direction of the placement box. The parallel movement of the second connecting rod will further transmit the movement to the two third connecting rods connected thereto, and the third connecting rods are connected to the second connecting ears on the box cover through a rotation connection, thereby driving the box cover to rotate around the rotation axis of the second shell and open or close.

[0013] In some possible implementations, the temporary blood storage device for clinical medical testing further includes a controller, which is in communication with each flip mechanism, and is provided with a first control switch, which is used to control each flip mechanism to open its corresponding box cover with one key. In this way, there is no need to operate the flip mechanisms one by one to open the box covers, thereby improving operation efficiency and saving time.

[0014] In some possible implementations, the controller is further provided with a second control switch, which is used to control each flip mechanism to close its corresponding box lid with one key, so that there is no need to operate the flip mechanisms one by one to close the box lids, thereby improving operation efficiency and saving time.

[0015] In some possible implementations, each placement box is provided with a pressure sensor, and each pressure sensor is connected to the controller in communication. The controller is also used to control the corresponding flip mechanism of the placement box to close the lid of the placement box when the pressure is greater than the set first threshold value according to the pressure information collected by the pressure sensor in a certain placement box. In this way, when the blood test tube is placed in the placement box, the pressure change caused by the weight of the blood test tube can be sensed by the pressure sensor, and the signal is transmitted to the controller in real time. The controller automatically controls the flip mechanism connected to the communication to perform the operation of closing the lid by analyzing the signal. In this way, on the one hand, it can replace the traditional manual operation of the lid to improve the operating efficiency; on the other hand, it can effectively avoid the risks caused by human operating errors (forgetting to close).

[0016] In some possible embodiments, a first accommodating cavity is provided inside the chassis, and a refrigeration assembly is arranged in the first accommodating cavity. The refrigeration assembly includes a refrigeration device, a plurality of micro air pumps, and a plurality of connecting hoses. The plurality of connecting hoses are arranged one-to-one with the plurality of micro air pumps, and each connecting hose is connected to the output port of the corresponding micro air pump. The plurality of connecting hoses are also arranged one-to-one with the plurality of placement boxes, and each connecting hose is connected to the internal space of the corresponding placement box. In this way, on the one hand, the placement box with the blood test tube can be refrigerated according to actual needs, without the need to transport cold air to the unused placement boxes, thereby reducing energy waste; on the other hand, independent refrigeration management between the placement boxes can be achieved, and even if the state of a placement box changes (such as opening the box cover), the refrigeration effect of other placement boxes will not be disturbed, and a stable low-temperature environment will be maintained.

[0017] In some possible implementations, a temperature sensor is disposed inside each placement box, and each temperature sensor is electrically connected to the controller; the controller is also used to control the micro air pump corresponding to the placement box to start when the pressure is greater than a set first threshold value based on the pressure information collected by the pressure sensor in a certain placement box, so as to transmit the cold air in the first accommodation chamber into the placement box;

[0018] The controller is also used to control the micro air pump corresponding to the placement box to turn off when the temperature is adjusted to a set temperature range according to the temperature information collected by the temperature sensor corresponding to the placement box;

[0019] The controller is also used to control the micro air pump corresponding to the placement box to start when the temperature information collected by the temperature sensor corresponding to the placement box is analyzed to deviate from the set temperature range, and when the pressure information collected by the pressure sensor in a certain placement box is analyzed to be greater than the set first threshold value. In this way, when the blood test tube is placed in the placement box, the pressure change caused by the weight of the blood test tube can be sensed by the pressure sensor, and the signal is transmitted to the controller in real time. By analyzing the signal, the controller automatically controls the micro air pump to start and transmit the cold air in the first accommodating chamber into the placement box where the blood test tube is placed. In this way, an automated and accurate temperature adjustment function is realized. By combining real-time monitoring of pressure and temperature and corresponding control logic, it can respond to changes in the environment in the placement box in a timely manner, automatically adjust the temperature, and maximize the guarantee that the blood sample is always in the best storage temperature state, thereby improving the quality and reliability of blood sample storage.

[0020] In addition, with such a configuration, when there is no blood test tube placed in the placement box, the pressure in the box will not exceed the set first threshold value. At this time, even if the temperature deviates, the controller will not start the micro air pump to work, thereby avoiding the waste of cold air transported to the placement box. When the pressure sensor detects that the pressure in the box is greater than the first threshold value, the controller can confirm that a blood test tube has been placed in the box. At this time, if the temperature deviates from the set range, the micro air pump will be started to transport cold air to the placement box to adjust the temperature in the box to the set range. In this way, the accuracy of cold air delivery is guaranteed, and only the placement box that is really needed is cooled, avoiding the ineffective consumption of cold air in the placement box.

[0021] In some possible implementations, a one-way valve is provided in each connecting hose, and each one-way valve is used to prevent the cold air in the placement box corresponding to the corresponding connecting hose from flowing back. In this way, the cold air in the placement box that has been adjusted to a certain temperature can be effectively prevented from flowing back, and the problems of reduced refrigeration efficiency and temperature fluctuation in the placement box caused by the cold air flowing back can be avoided, which helps to maintain the stability of the temperature in the placement box and ensure the constant temperature of the blood sample storage environment.

[0022] In some possible implementations, a flexible pad is provided on the inner wall surface of the placement box, so that when the sample contacts the flexible pad, the flexible pad absorbs and buffers the impact force generated during the contact by its own elastic deformation, thereby avoiding damage to the sample.

[0023] In some possible implementations, a limiting ring is provided on the circumferential side wall of the second shell, and the second shell is mounted on the first shell through the limiting ring, so that there is a distance between the bottom plate of the first shell and the bottom plate of the second shell.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] It should be noted that, in the description of the present invention, terms such as "center", "upper", "lower", "horizontal", "inner", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0037] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] See also Figure 1 Combined with Figure 2 and Figure 3The embodiment of the present application provides a temporary blood storage device for clinical medical testing, including a chassis 1, a plurality of placement boxes 2, a plurality of flip mechanisms 3 and a refrigeration assembly 4, each placement box 2 is arranged on the chassis 1; the plurality of flip mechanisms 3 are arranged one by one with the plurality of placement boxes 2, each flip mechanism 3 is used to control the automatic opening and closing of the box cover 23 of the corresponding placement box 2; the refrigeration assembly 4 is used to adjust the temperature of the internal space of each placement box 2. It can be understood that the number of placement boxes 2 is determined according to actual needs and is not limited here.

[0039] In this way, a relatively closed storage space can be provided by multiple placement boxes 2. When the blood test tube 8 is placed in the placement box 2, the closing state of the box cover 23 is controlled by the flip mechanism 3, so that the blood test tube 8 is effectively sealed, and dust and pollutants in the air are prevented from contacting the blood test tube 8, thereby reducing the risk of contamination. At the same time, the design of the refrigeration component 4 provides a constant low-temperature environment inside the placement box 2, so that the blood sample can be kept at a suitable storage temperature, and the adverse effects of external temperature fluctuations on the quality of the blood sample can be avoided. In summary, the temporary storage quality of the blood sample can be improved.

[0040] See also Figure 3-Figure 7 In some embodiments, the placement box 2 includes a first shell 21 and a second shell 22. The first shell 21 is sleeved on the outside of the second shell 22. The first shell 21 includes a first side plate 211, and the second shell 22 includes a second side plate 221. The first side plate 211 and the second side plate 221 are arranged opposite to each other, and there is a gap between the first side plate 211 and the second side plate 221 to form a first accommodating space 24; there is a gap between the bottom plate of the first shell 21 and the bottom plate of the second shell 22 to form a second accommodating space 25, and the first accommodating space 24 is connected to the second accommodating space 25;

[0041] The flip mechanism 3 includes a first connecting rod 31, a first connecting ear 32, a second connecting rod 33, a third connecting rod 34, a second connecting ear 35, and a telescopic device 36; illustratively, the telescopic device 36 can be a micro electric cylinder.

[0042] The first connecting rod 31 and the first connecting ear 32 are arranged in the second accommodating space 25, the first connecting ear 32 is fixedly connected to the first shell 21, the first connecting rod 31 includes a first connecting section 311 and a second connecting section 312, the connection between the first connecting section 311 and the second connecting section 312 is rotatably connected to the first connecting ear 32, and the end of the first connecting section 311 away from the second connecting section 312 is higher than the connection between the first connecting section 311 and the second connecting section 312; the telescopic rod of the telescopic device 36 is fixedly connected to the end of the first connecting section 311 away from the second connecting section 312; One end of the second connecting section 312 away from the first connecting section 311 is rotatably connected to one end of the second connecting rod 33. The second connecting rod 33 is arranged in the first accommodating space 24. The extension direction of the second connecting rod 33 is parallel to the central axis of the placement box 2. The other end of the second connecting rod 33 extends out of the second accommodating space 25 and is rotatably connected to one end of two third connecting rods 34. The other ends of the two third connecting rods 34 are rotatably connected to the second connecting ear 35. The second connecting ear 35 is fixedly connected to the box cover 23; the box cover 23 is rotatably connected to the second shell 22.

[0043] In this way, when the telescopic device 36 is extended and retracted, the first connecting rod 31 rotates around the first connecting ear 32, thereby driving the second connecting rod 33 connected thereto to move along the central axis direction of the placement box 2. The parallel movement of the second connecting rod 33 will further transmit the movement to the two third connecting rods 34 connected thereto, and the third connecting rods 34 are connected to the second connecting ears 35 on the box cover 23 through a rotational connection, thereby driving the box cover 23 to rotate around the rotation axis of the second shell 22 and open or close.

[0044] For example, in Figure 3 In the illustrated embodiment, the telescopic device 36 is located below the first connecting section 311 away from the second connecting section 312. It can be understood that at this time, the telescopic length of the telescopic rod of the telescopic device 36 when the box cover 23 is opened is less than the telescopic length of the telescopic rod of the telescopic device 36 when the box cover 23 is closed. When the telescopic rod is shortened, it will drive the first connecting rod 31 to move downward away from one end of the second connecting rod 33, so that the first connecting rod 31 rotates around the connection, so that the first connecting rod 31 moves upward close to one end of the second connecting rod 33, and then drives the second connecting rod 33 to move upward. The upward movement of the second connecting rod 33 drives the two third connecting rods 34 rotatably connected to the second connecting rod 33 to move, and finally the box cover 23 rotates around the connection point between it and the second shell 22 to open.

[0045] Of course, the present application is not limited thereto. In other embodiments, the telescopic device 36 is located above the first connecting section 311 away from the second connecting section 312 .

[0046] In some embodiments, a limiting ring 222 is provided on the circumferential side wall of the second housing 22, and the second housing 22 is mounted on the first housing 21 through the limiting ring 222, so that there is a gap between the bottom plate of the first housing 21 and the bottom plate of the second housing 22. In this way, the connection stability between the placement box 2 and the chassis 1 is enhanced, and the structural instability problem that may occur due to loose connection parts is reduced, making the entire device more reliable during use.

[0047] See also Figure 1 In some embodiments, the temporary blood storage device for clinical medical testing further includes a controller 5, which is in communication connection with each flip mechanism 3. Specifically, the controller 5 is electrically connected with the telescopic device 36 of each flip mechanism 3. The controller 5 is provided with a first control switch 51, which is used to control each flip mechanism 3 to open its corresponding box cover 23 with one key. In this way, there is no need to operate the flip mechanisms 3 one by one to open the box covers 23, thereby improving the operation efficiency and saving time.

[0048] See also Figure 1 In some embodiments, the controller 5 is further provided with a second control switch 52, which is used to control each flip mechanism 3 to close its corresponding box cover 23 with one key. In this way, there is no need to operate the flip mechanisms 3 one by one to close the box covers 23, thereby improving the operating efficiency and saving time.

[0049] See also Figure 3 In some embodiments, each placement box 2 is provided with a pressure sensor 6, and each pressure sensor 6 is connected to the controller 5 in communication. The controller 5 is also used to control the corresponding flip mechanism 3 of the placement box 2 to close the lid 23 of the placement box 2 when the pressure is greater than the set first threshold value according to the pressure information collected by the pressure sensor 6 in a certain placement box 2. In this way, when the blood test tube 8 is placed in the placement box 2, the pressure change caused by the weight of the blood test tube 8 can be sensed by the pressure sensor 6, and the signal is transmitted to the controller 5 in real time. The controller 5 automatically controls the flip mechanism 3 connected to the communication with it to perform the operation of closing the lid 23 by analyzing the signal. In this way, on the one hand, the traditional manual operation of the lid 23 can be replaced to improve the operation efficiency; on the other hand, the risk caused by human operation errors (forgetting to close) can be effectively avoided.

[0050] See also Figure 3In some embodiments, a first accommodating chamber 11 is provided inside the chassis 1, and a refrigeration assembly 4 is disposed inside the first accommodating chamber 11. The refrigeration assembly 4 includes a refrigeration device 41, a plurality of micro air pumps 42, and a plurality of connecting hoses 43. The plurality of connecting hoses 43 are disposed in a one-to-one correspondence with the plurality of micro air pumps 42, and each connecting hose 43 is connected to the output port of the corresponding micro air pump 42. The plurality of connecting hoses 43 are also disposed in a one-to-one correspondence with the plurality of placement boxes 2, and each connecting hose 43 is connected to the internal space of the corresponding placement box 2. Specifically, each connecting hose 43 is connected to the internal space of the second shell 22 of the corresponding placement box 2.

[0051] For example, in Figure 8 In the illustrated embodiment, the connecting hose 43 is connected to the circumferential wall of the placement box 2. It is understandable that, at this time, the chassis 1 needs to be provided with a through hole for the connecting hose 43 to pass through.

[0052] In this way, on the one hand, the placement box 2 containing the blood test tube 8 can be refrigerated according to actual needs, without the need to transport cold air to the unused placement boxes 2, thereby reducing energy waste; on the other hand, independent refrigeration management between the placement boxes 2 can be achieved, even if the state of a certain placement box 2 changes (such as opening the box cover 23), the refrigeration effects of other placement boxes 2 will not be disturbed, and a stable low-temperature environment will be maintained.

[0053] Exemplarily, the refrigeration device 41 may be any mature existing technology, for example, a semiconductor refrigeration device 41 or a micro compressor refrigeration device 41 or a refrigeration structure disclosed in the prior application CN218143240U.

[0054] In another exemplary embodiment, the refrigeration device 41 is mounted on the circumferential wall surface of the first accommodating chamber 11. A plurality of micro air pumps 42 are arranged on the bottom wall surface of the first accommodating chamber 11. Of course, the present application is not limited thereto. In other embodiments, the refrigeration device 41 is mounted on the bottom wall surface of the first accommodating chamber 11, and a plurality of micro air pumps 42 are fixedly arranged on the circumferential wall surface of the first accommodating chamber 11 by a mounting frame.

[0055] See also Figure 3 In some embodiments, a temperature sensor 7 is disposed inside each placement box 2, and each temperature sensor 7 is electrically connected to the controller 5; the controller 5 is also used to control the micro air pump 42 corresponding to the placement box 2 to start when the pressure is greater than a set first threshold value according to the pressure information collected by the pressure sensor 6 in a certain placement box 2, so as to transmit the cold air in the first accommodation cavity 11 into the placement box 2;

[0056] The controller 5 is also used to control the micro air pump 42 corresponding to the placement box 2 to turn off when the temperature is adjusted to a set temperature range according to the temperature information collected by the temperature sensor 7 corresponding to the placement box 2;

[0057] The controller 5 is also used to control the micro air pump 42 corresponding to the placement box 2 to start when the temperature information collected by the temperature sensor 7 corresponding to the placement box 2 is analyzed to deviate from the set temperature range, and when the pressure information collected by the pressure sensor 6 in a certain placement box 2 is analyzed to be greater than the set first threshold value. In this way, when the blood test tube 8 is placed in the placement box 2, the pressure change caused by the weight of the blood test tube 8 can be sensed by the pressure sensor 6, and the signal is transmitted to the controller 5 in real time. By analyzing the signal, the controller 5 automatically controls the micro air pump 42 to start, and transmits the cold air in the first accommodating chamber 11 into the placement box 2 where the blood test tube 8 is placed. In this way, an automated and accurate temperature adjustment function is realized. By combining the real-time monitoring of pressure and temperature and the corresponding control logic, it can respond to the changes in the environment in the placement box 2 in a timely manner, automatically adjust the temperature, and maximize the guarantee that the blood sample is always in the best storage temperature state, thereby improving the quality and reliability of blood sample storage.

[0058] In addition, with such a configuration, when the blood test tube 8 is not placed in the placement box 2, the pressure in the box will not exceed the set first threshold value. At this time, even if the temperature deviates, the controller 5 will not start the micro air pump 42 to work, thereby avoiding the waste of cold air transported to the placement box 2. When the pressure sensor 6 detects that the pressure in the box is greater than the first threshold value, the controller 5 can confirm that the blood test tube 8 has been placed in the box. At this time, if the temperature deviates from the set range, the micro air pump 42 will be started to transport cold air to the placement box 2 to adjust the temperature in the box to the set range. In this way, the accuracy of cold air transport is guaranteed, and only the placement box 2 that is really needed is cooled, avoiding the ineffective consumption of cold air in the placement box 2.

[0059] See also Figure 8 In some embodiments, a one-way valve 431 is provided in each connecting hose 43, and each one-way valve 431 is used to prevent the cold air in the placement box 2 corresponding to the corresponding connecting hose 43 from flowing back. In this way, the cold air with adjusted temperature in the placement box 2 can be effectively prevented from flowing back, and the problems such as reduced refrigeration efficiency and temperature fluctuation in the placement box 2 caused by the cold air backflow can be avoided, which helps to maintain the stability of the temperature in the placement box 2 and ensure the constant temperature of the blood sample storage environment.

[0060] In some embodiments, a flexible pad (not shown) is provided on the inner wall surface of the placement box 2. Specifically, the connection can be fixed by gluing. Exemplarily, the flexible pad can be a rubber pad. Of course, the present application is not limited to this. In other embodiments, the flexible pad can also be a latex pad or a silicone pad. In this way, when the sample contacts the flexible pad, the flexible pad uses its own elastic deformation to absorb and buffer the impact force generated during contact, avoiding damage to the sample.

[0061] The present invention and its embodiments are described above, and such description is not restrictive. What is shown in the full text is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
