Description

Technical Field

[0001] This utility model relates to the field of medical testing device technology, and in particular to a preliminary testing device before umbilical cord blood separation. Background Technology

[0002] Umbilical cord blood refers to the blood remaining in the placenta and umbilical cord after the baby is born and the cord is tied and cut. Umbilical cord blood contains a large number of stem cells, including hematopoietic stem cells and various other stem cells, collectively known as umbilical cord blood stem cells. Umbilical cord blood hematopoietic stem cells have been used to save lives for over 30 years. Currently, there are numerous clinical studies on the regenerative medicine applications of umbilical cord blood, aiming to utilize umbilical cord blood stem cells to promote the repair of damaged tissues and organs.

[0003] After umbilical cord blood is retrieved, the first step is to test the number of stem cells in it. This is because stored umbilical cord blood is essentially stored stem cells. If there are too few or no stem cells, it has no value for storage. It is also necessary to check for infectious diseases, such as hepatitis B, syphilis, and HIV. Therefore, a testing device is needed to perform an initial test on the umbilical cord blood before separation.

[0004] However, the existing testing device requires the testing personnel to manually place the test tube containing umbilical cord blood onto the testing head of the device, and after each test, the testing personnel need to manually wipe and disinfect the probe with a sterile cotton cloth, which is inconvenient and inefficient.

[0005] Currently, a search reveals that Chinese utility model patent CN211697833U discloses a fully automated intelligent blood cell analyzer, comprising an analyzer body (1), a probe (2), a base (3), and a housing (4). While the aforementioned patent can improve the test tube positioning seat to allow blood in the test tube to contact the probe for detection, it still has the following technical drawbacks:

[0006] On the one hand, the test tube positioning holder can only hold a single test tube, and after each test, the testing personnel need to manually remove the test tube for replacement, which is inefficient;

[0007] On the other hand, after the blood test in the test tube is completed, the testers need to manually clean the probes, which increases the workload of the testers.

[0008] Another issue is that it is inconvenient to remove the test tubes, as they need to be taken directly out of the positioning slot.

[0009] In view of the many defects and shortcomings of the above-mentioned testing instruments, such as low efficiency, inconvenient cleaning, and difficulty in removing test tubes, the key to solving the above technical problems lies in developing a more practical and efficient pre-testing device for umbilical cord blood separation. Summary of the Invention

[0010] In view of the many defects and deficiencies in the above-mentioned background technology, this utility model has made improvements and innovations, aiming to provide a device for preliminary detection before umbilical cord blood separation. It can simultaneously place multiple test tubes and detect them sequentially. The test tubes are rotated by a motor-driven movable plate, and the test tubes are lifted by a telescopic rod, so that the probes come into contact with the blood in the test tubes, thereby improving work efficiency.

[0011] Another objective of this invention is to install a cleaning element between test tubes and allow the cleaning core to absorb disinfectant. After the probe has finished testing a test tube, the motor drives the movable plate to rotate, thereby driving the cleaning element to clean the probe. This effectively solves the problem of manual cleaning by the testing personnel after each test, thus improving work efficiency.

[0012] Another objective of this invention is to set protrusions at symmetrical positions of the probe. When the movable plate rotates the test tube, the protrusions lift the test tube from low to high, so that the mouth of the test tube is away from the movable plate, making it easier for the testing personnel to remove the test tube from the movable plate.

[0013] To solve the above problems and achieve the objectives of the invention, this utility model provides a preliminary detection device for umbilical cord blood separation, implemented through the following design structure and technical solution:

[0014] A preliminary detection device for umbilical cord blood separation includes a test tube rack, a control circuit, and a main unit installed on the detection equipment. The main unit and the control circuit are connected by wired or wireless means. The detection equipment is equipped with a touch screen and probes. The test tube rack includes:

[0015] The base is set on the testing equipment, and a telescopic rod is provided in the middle of the base, which is connected to the movable plate through the telescopic rod.

[0016] The movable plate has several test tube mounting holes, and cleaning components are placed between each mounting hole;

[0017] The telescopic rod is connected to the center of the movable plate through a support shaft that passes through it, allowing the movable plate to reciprocate in the vertical direction.

[0018] The transmission mechanism is mounted on the base and is linked to a motor to make the movable plate rotate around the central axis.

[0019] The touch screen, probe, telescopic rod, motor, and control circuit within the testing equipment are electrically connected.

[0020] Preferably, the transmission mechanism includes:

[0021] The motor is mounted on the base and connected to the transmission gear via a drive shaft.

[0022] The transmission gear meshes with the internal gear ring.

[0023] The internal gear ring has a positioning component extending downwards. The internal gear ring is fixed to the base by a retaining ring. Under the linkage of the transmission gear, the internal gear ring rotates around the central axis of the base.

[0024] Limiting rods, which are designed in several ways, have one end that passes through a pre-drilled hole in the movable plate and connects to the internal toothed ring, and the other end that is provided with an end head to limit the longitudinal movement of the movable plate;

[0025] The motor drives the transmission gear to rotate, which in turn drives the internal gear ring to move the limit rod and the movable plate to rotate.

[0026] Preferably, the cleaning component includes:

[0027] The cleaning tank is an arc-shaped "U" groove structure that matches the movement trajectory of the probe, allowing the probe to move inside the cleaning tank. A mounting part is provided below it.

[0028] The mounting section is detachably connected to the movable plate.

[0029] Handheld part, which is arranged horizontally along the wall of the cleaning tank, is used for assembling and disassembling cleaning parts;

[0030] The cleaning core is placed inside the cleaning tank and fits into the probe.

[0031] Preferably, the base further includes:

[0032] The bump is located at the symmetrical end of the probe. It is a structure that is low at both ends and gradually increases towards the middle. It is used to lift the test tube when the movable plate rotates, making it easy to pick up.

[0033] Preferably, the positioning element is a ring-shaped structure with an "L"-shaped cross-section, which is embedded in the base to limit the lateral and longitudinal movement of the internal toothed ring.

[0034] Preferably, the cleaning core is made of a soft material and absorbs disinfectant or alcohol.

[0035] Preferably, the detection device is powered by an external power source connected to a power cord and by a control circuit via wires;

[0036] The control circuit provides power to the touch screen, probes, telescopic rods, and motors after voltage division.

[0037] Preferably, the control circuit is a PLC control board, including a signal receiving unit, a data processing unit, and a signal transmission unit. The signal receiving unit receives control signals from the touch screen, receives operating signals from the telescopic rod and the motor, and receives detection data from the probe. After calculation by the data processing unit, the signal transmission unit controls the telescopic rod to rise and fall, controls the motor to run and stop, and transmits and displays the detection data to the touch screen and the host computer.

[0038] The working principle is as follows: In the above-described pre-examination device for umbilical cord blood separation, during use, the motor 241 drives the transmission gear 242 to rotate, which in turn drives the internal gear ring 243 to rotate. The internal gear ring 243 drives the limiting rod 244, which in turn drives the movable plate 22 to rotate. The rotation of the movable plate 22 is controlled by the control circuit to calculate the number of rotations of the motor, and stops when the test tube 3 is directly below the probe. The control circuit then controls the telescopic rod 23 to extend the support shaft 231 away from the base 21, thereby raising the height of the movable plate 22 and allowing the probe 12 to move further away from the base 21. The probe 12 enters test tube 3 and comes into contact with the blood inside. After obtaining the test information, it is stored in the testing device 1 and sent to the host. The required blood information is recorded. Then, the control circuit controls the support shaft 231 to move to one side of the base 21, lowering the height of the movable plate 22, so that the probe 12 leaves the test tube 3. The motor 241 runs again, and the movable plate 22 rotates in conjunction with it. At this time, the probe 12 enters from one end of the cleaning element 4, is cleaned by the cleaning core 44, and exits from the other end of the cleaning element 4, and is located directly above the test tube 3. By repeating the above testing operation, subsequent test tubes 3 are tested.

[0039] At the symmetrical position of probe 12, the test tube 3 that has been tested comes into contact with the protrusion 211 due to the rotation of the movable plate 22, and is lifted by the arc structure of the protrusion 211 from low to high, so that the mouth of the test tube is away from the movable plate 22, making it easier for the tester to take it out.

[0040] After removing the test tube 3 after testing, the testing personnel remove the used cleaning part 4 by pinching the handle 43 and replace it with a new cleaning part 4 to ensure that the probe 12 is disinfected and cleaned in subsequent operations, prevent contamination, and ensure the accuracy of the test results.

[0041] In summary, the beneficial effects of this utility model compared with the prior art are as follows:

[0042] 1. This utility model, by setting up a control circuit to control the motor and telescopic rod, thereby driving the movable plate to rotate and lift, enables the simultaneous testing of multiple test tubes, solving the shortcomings of low efficiency and low degree of automation that testing personnel can only test one test tube at a time;

[0043] 2. This utility model has a cleaning component that is designed to work with the probe trajectory in the test tube room. After cleaning, the probe is disinfected and cleaned by the cleaning component, which solves the inconvenience of manual cleaning by the testing personnel in a small space after each test.

[0044] 3. This utility model features protrusions at symmetrical positions on the probe, which lift the test tube, making it easier for testing personnel to remove the test tube.

[0045] 4. This utility model provides an installation part and a hand-held part on the cleaning part, which makes it convenient for testing personnel to disassemble and assemble the cleaning part, replace the used cleaning part in a timely manner, and prevent contamination caused by inadequate cleaning in subsequent operations.

[0046] 5. By setting a limiting rod, this utility model allows the movable plate to rise and fall vertically under the limiting action of the limiting rod, thus avoiding the situation where the movable plate tilts, causing the probe to be in an incorrect position and thus damaging the probe.

[0063] To make the technical means, inventive features, and achieved objectives and effects of this utility model readily understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0064] Example 1

[0065] like Figures 1 to 11 The device shown is a preliminary detection device for umbilical cord blood separation, comprising a test tube rack 2, a control circuit, and a main unit mounted on a detection device 1. The main unit and the control circuit are connected by wired or wireless means. The detection device 1 is equipped with a touch screen display 11 and probes 12. The test tube rack 2 includes:

[0066] Base 21 is mounted on the testing equipment 1, and a telescopic rod 23 is provided in the middle of the base, which is connected to the movable plate 22 through the telescopic rod 23.

[0067] The movable plate 22 has several test tube 3 mounting holes, and a cleaning component 4 is provided between each mounting hole;

[0068] The telescopic rod 23 is connected to the center of the movable plate 22 through the support shaft 231 that passes through it, so that the movable plate 22 can perform reciprocating motion in the vertical direction.

[0069] The transmission mechanism 24 is mounted on the base 21 and is linked by the motor 241 to the movable plate 22, causing the movable plate 22 to rotate around the central axis.

[0070] The touch screen 11, probe 12, telescopic rod 23, motor 241 and control circuit in the detection equipment 1 are electrically connected.

[0071] Furthermore, the transmission mechanism 24 includes:

[0072] Motor 241 is mounted on base 21 and connected to transmission gear 242 via transmission shaft;

[0073] Transmission gear 242 meshes with internal gear ring 243;

[0074] The internal gear ring 243 has a positioning element 2431 extending downwards. The internal gear ring 243 is fixed to the base 21 by a retaining ring 212. Under the linkage of the transmission gear 242, the internal gear ring 243 rotates around the central axis of the base 21.

[0075] Limiting rod 244, there are several designs of limiting rod 244, one end passes through the preset hole of the movable plate 22 and is connected to the internal tooth ring 243, and the other end is provided with an end head to limit the longitudinal movement of the movable plate 22;

[0076] Among them, the motor 241 drives the transmission gear 242 to rotate, which in turn drives the internal gear ring 243 to drive the limit rod 244, which in turn drives the movable plate 22 to rotate.

[0077] Before using the pre-examination device for umbilical cord blood separation with the above-described design structure, first install the telescopic rod 23 and the motor 241 to the fixed position of the base 21. Then, install the transmission gear 242 on the transmission shaft of the motor 241. Use the retaining ring 212 to fix the internal gear ring 243 to the base and mesh it with the transmission gear 242. Place the movable plate 22 onto the end of the support shaft 231. Use the limiting rod 244 to pass through the hole provided on the movable plate 22 and connect it to the internal gear ring 243. Figure 6 As shown, the telescopic rod 23 and the motor 241 are connected to the control circuit via wires. Adjust the position of the base 21 so that the protrusion 211 is positioned symmetrically to the probe 12. Fix the base 21 to the preset position on the detection device 1, as shown. Figure 1 As shown, the installation of this utility model is now complete.

[0078] During use, the testing personnel turn on the equipment power, illuminate the touch screen 11, and press the placement option. The control circuit signal receiving unit receives the signal, calculates the number of rotations required for motor 241 through the data processing unit, and transmits the signal to motor 241 through the signal transmission unit, causing motor 241 to rotate a fixed number of times and then stop. At this time, the testing personnel place the test tube 3 containing blood into the test tube hole and install the cleaning component 4. After installation, the personnel press the up / down / next option on the touch screen 11. Motor 241 drives the movable plate 22 to rotate counterclockwise a fixed distance and then stops. The testing personnel repeat the above steps until the test tube 3 and cleaning component 4 are installed. At this time, the touch screen 11 displays "Placement complete, please start testing". When the testing personnel press the start option, the control circuit controls the telescopic rod 23 to push out the support shaft 231, thereby raising the movable plate 22. At this time, the limit rod 244 limits the movable plate 22, causing the movable plate 22 to vertically displace a fixed distance, allowing the probe 12 to enter the test tube 3 and contact the blood. Figure 3 As shown, at this time, the signal receiving unit receives the data detected by the probe 12 and transmits it to the touch screen 11 and the host through the signal transmission unit, displaying the number information and detection data. Then, a return end signal causes the support shaft 231 to retract into the telescopic rod 23. Under the action of gravity, the movable plate 22 moves downward with the support shaft 231, causing the probe 12 to leave the test tube. Figure 4 As shown, after the support shaft 231 is fully retracted, the control circuit controls the motor to rotate a fixed distance. At this time, the probe 12 passes through the cleaning tank 41 and is cleaned by the cleaning core 44 until the probe 12 is directly above the next test tube 3. Then, the motor 241 stops running, and the telescopic rod 23 repeats the above operation to test the blood in the next test tube 3. When the number of test record data entries matches the number of test tubes 3, the touch screen 11 displays the word "Replace". The tester removes the test tube 3 from the symmetrical side of the probe 12. At this time, the test tube 3 is lifted upward by the protrusion 211. Figure 2 As shown, this allows the testing personnel to easily remove the test tube 3. At the same time, they can pinch the handle 43 of the cleaning component 4 to remove the cleaning component 4. By repeating the above operation, a new batch of test tubes 3 to be tested can be placed, and a new cleaning component 4 can be replaced to start a new round of testing.

[0079] After use, the testing personnel disposed of the used cleaning kit 4 and test tube 3 according to the operating procedure, disconnected the power, and waited for the next blood test.

[0080] In this invention, the testing personnel operate the touch screen 11. After receiving the operation signal, the signal receiving unit in the control circuit converts it and controls the raising and lowering of the telescopic rod 23 and the rotation of the motor 241 by a fixed number of turns through the signal transmission unit. This causes the movable plate 22 to rotate at a fixed angle, ensuring that all test tubes 3 are directly below the probe 12. The detected blood data is transmitted to the touch screen 11 for the testing personnel to view through the signal transmission unit, and also transmitted to the host computer for the testing personnel to register and write reports.

[0081] The control methods described above, which use the touch screen 11 and PLC board to achieve the above functions, are all conventional technologies in this field and do not involve improvements to computer software control. This section only describes the operation process, and the specific principles and methods will not be elaborated here.

[0082] Example 2

[0083] This embodiment 2 is the same as embodiment 1, the only difference being that the cleaning core 44 has a wavy structure, which absorbs disinfectant or alcohol. Through the design of the wavy structure, such as... Figure 10 As shown, the cleaning core 44 is disposed inside the cleaning tank 41 and fits against the probe 12, so that the probe 12 can be cleaned better and prevent the detection results from being affected by poor cleaning in subsequent operations.

[0084] Example 3

[0085] This embodiment 3 is the same as embodiment 1, except that the cleaning core 44 is a staggered brush structure and is coated with disinfectant or alcohol. Figure 11 As shown, the cleaning core 44 is disposed inside the cleaning tank 41 and fits against the probe 12, cleaning the probe surface as the probe 12 moves.

[0086] In this invention, the design of the cleaning core 44 with its soft material can effectively prevent damage to the probe 12 during the cleaning process.

[0087] In this utility model, the connection is either a fixed connection or a detachable connection. The fixed connection is either a welded connection or a directly machined integral structure, while the detachable connection is either an internal or external threaded connection, a snap-fit ​​connection, or a plug-in structure connection.

[0088] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
