Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a sample tube detection and commutation mechanism, a sorting device and a pneumatic transmission device. Background Art

[0002] Medical samples, such as blood collection samples, urine samples, etc., are common medical samples in hospitals and are usually contained in sample tubes. After medical staff collect medical samples, they need to manually transfer the samples to a medical testing room for subsequent staff to test and analyze the samples.

[0003] However, the testing speed of medical samples is limited by the collection speed of medical samples. For example, for most hospitals, usually staff collect samples within a certain period of time, and then the staff transport the collected samples to the testing room. After the testing room staff finish testing the samples, they also need to re-organize the tested samples. Conventional sample transportation is mostly completed by people, and it will also affect the transportation staff during the transportation process. Therefore, the existing transportation efficiency of such medical samples is very low, and the samples will also be contaminated during the handling process, or damaged samples will contaminate other samples, seriously affecting the processing speed of the samples.

[0004] In addition, if the samples are exposed to the air for a long time during the transportation process, it will not only affect the samples, but also is very likely to pollute the environment. For example, for virus detection samples, the transportation of samples not only requires high speed, but also needs to keep the samples as clean as possible, and there is no interference between samples. However, it is difficult to avoid the samples being exposed to the air during the conventional sample transportation.

[0005] In view of the above problems, automatic pneumatic transmission devices have been developed in the prior art. During the batch production / processing of blood collection tubes, in order to facilitate processing, it is often necessary to adjust the orientations of the openings of the blood collection tubes to be consistent.

[0006] In the prior art, some use manual flipping to flip the blood collection tubes, which results in low work efficiency, and manual contact with the blood collection tubes increases the risk of contaminating the blood collection tubes and it is difficult to ensure the cleanliness of the blood collection tubes. Some use a robotic arm to clamp the blood collection tube and flip it, but its structure is complex and the cost is high. Summary of the Utility Model

[0007] Aiming at the deficiencies in the prior art, the first object of the present utility model is to provide a sample tube detection and commutation mechanism, which can automatically detect the orientation of the sample tube and change its direction to a unified direction, and has a simple structure, is convenient for processing and manufacturing, and has a low cost. The sample tube can be a blood collection tube, a urine tube, etc.

[0008] To achieve the above object, the utility model adopts the following technical solutions:

[0009] A sample tube detection commutation mechanism, comprising: a sorting channel, a detection unit and a commutation unit. The extending direction of the sorting channel is set to be parallel to the axial direction of the sample tube. The detection unit includes a light source, an induction module and a stopper. The light source is arranged to irradiate into the sorting channel along the radial direction of the sample tube and can be received by the induction module. One end of the stopper can be inserted into / removed from the sorting channel; the commutation unit has a body and an adjustment module. The body is provided with an inlet and an outlet. One end of the inlet is communicated with the sorting channel; the adjustment module has a cavity. The adjustment module is rotatably connected to the inside of the body so that its cavity is communicated with the other end of the inlet or its cavity is communicated with the outlet.

[0010] The working process of the utility model is as follows:

[0011] During detection, the stopper is first inserted into the sorting channel. Since the extending direction of the sorting channel is set to be parallel to the axial direction of the sample tube, during the sliding process of the sample tube along the sorting channel, it always maintains a posture with its axis parallel to the length direction of the sorting channel. When the head / tail of the sample tube moves to contact the stopper, the sample tube stops moving; if the head of the sample tube is downward, at this time the light source irradiates the head of the sample tube along the radial direction of the sample tube. Since the head of the sample tube (generally a plug) is opaque and the light beam cannot penetrate, the induction module outputs a first signal. If the head of the sample tube is upward, at this time the light source irradiates the tail of the sample tube along the radial direction of the sample tube. Since the tail of the sample tube (generally a transparent glass / plastic) is transparent, at this time the light beam penetrates the tail of the sample tube and irradiates on the induction module, and the induction module outputs a second signal.

[0012] During commutation, the stopper is removed from the sorting channel. At this time, the sample tube slides through the inlet into the cavity of the adjustment module. The adjustment module rotates clockwise / counterclockwise by different angles according to the feedback of the first signal / second signal until the head of the sample tube is all upward / downward.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] This detection and commutation mechanism can automatically detect and commutate the sample tube, improving the efficiency and reducing the pollution risk compared with the manual commutation method; in addition, the structures, movement paths and control logics of the components of this mechanism are simple, which is convenient for processing and manufacturing and has a low cost.

[0015] Another object of the present utility model is to provide a sample tube sorting device, which includes the above-mentioned sample tube detection and commutation mechanism, and further includes a mounting rack, a plugging unit, a transfer unit and a collection channel. The tops of the sorting channel and the collection channel are both open and they are fixedly arranged side by side on the mounting rack. The plugging unit can move relative to the mounting rack to block the open top of the sorting channel or the collection channel. The transfer unit is movably connected to the mounting rack and the bottom of the transfer unit is open to communicate with the sorting channel or the collection channel.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] When applying this detection and commutation structure to the sample tube sorting device, in addition to the above beneficial effects, it also has the following beneficial effects:

[0018] The sorting device detects whether the sample tube meets the preset requirements for entering the sorting channel. If it meets the requirements, the controller of the sorting device controls the transfer unit to move the sample tube to the upper part of the sorting channel together. At this time, the transfer unit is communicated with the sorting channel, and the sample tube falls into the sorting channel. If the sorting device detects that the sample tube does not meet the requirements for entering the sorting channel, the controller controls the plugging unit to move until the open top of the sorting channel is blocked. Then, it controls the transfer unit to move the sample tube to the upper part of the collection channel together. At this time, the transfer unit is communicated with the collection channel, and the sample tube falls into the collection channel. Applying this structure to the sorting device can automatically sort the sample tubes according to requirements, improving work efficiency and accuracy.

[0019] As a preferred solution, it further includes a scanning unit. The scanning unit has a platform for placing the sample tube, and the platform, the sorting channel and the collection channel are arranged in sequence along the moving direction of the transfer unit.

[0020] As a preferred solution, there are two groups of sorting channels, and the two groups of sorting channels are distributed on both sides of the platform along the moving direction of the transfer unit.

[0021] As a preferred solution, the plugging unit is located between the sorting channel and the collection channel, and the plugging unit is rotatably connected to the mounting rack.

[0022] As a preferred solution, the platform includes a power roller group having two groups of rollers.

[0023] As a preferred solution, the cavity is a through hole penetrating the adjustment module; it further includes a pneumatic conveying unit having an upper air duct, a lower air duct and an air source module. The cavity is located between the upper air duct and the lower air duct and can communicate the two air ducts, and the air source module is communicated with the upper air duct / the lower air duct.

[0024] Another object of the present utility model is to provide a pneumatic transmission device for sample tubes, comprising the sample tube sorting device described in any one of the above.

[0025] This pneumatic transmission device for sample tubes saves the turnover time of blood collection tube labels and is a new type of device that is fast, safe, and accurate. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0034] The following describes some embodiments of the present utility model with reference to the drawings:

[0035] The present utility model provides a sample tube detection commutation mechanism. For the convenience of understanding this technical solution, the sorting mechanism 3 is described in combination with the sample tube sorting device. The purpose of the sorting device is to sort out the sample tubes 8 that meet the screening requirements. In the embodiments herein, the example of sorting labeled and unlabeled sample tubes 8 is taken.

[0036] Specifically, as Figure 1 shown, the sample tube sorting device includes a box body 1, a controller, a scanning unit 2, and a sorting mechanism 3, where:

[0037] The box body 1 is a frame structure surrounded by various sheet metal parts. The box body 1 provides a mounting fulcrum for the components mounted on the box body 1 and protects the components mounted inside the box body 1.

[0038] Combined with Figure 2 and Figure 3 shown, the scanning unit 2 includes a platform 202 and a scanner 201. The sample tube 8 is transported to the platform 202 through the added transportation structure 4; the scanner 201 generates a light beam to scan the sample tube 8 located on the platform 202, thereby collecting information and transmitting a signal to the controller (this information can be the information for judging whether the sample tube 8 is labeled as described above, or can distinguish type A tubes / type B tubes, etc. according to different content information recorded on the label, and is set according to actual needs). It should be understood that the present utility model does not make improvements to the inherent structures and working principles of the scanner 201, the transportation structure 4, and the controller. For example, the transportation structure 4 can be designed as a stepped pusher plate with reference to the patents with publication numbers CN118083550A / CN212397347U, or designed with reference to the patent with publication number CN208103099U, etc. The controller can be a PLC controller or a single-chip microcomputer, and will not be elaborated herein.

[0039] As Figure 2As shown, the sorting mechanism 3 includes a mounting frame, a blocking unit 301, a transfer unit 302, a sorting channel 303 and a collecting channel 304, wherein:

[0040] The tops of the sorting channel 303 and the collecting channel 304 are both open, and the sorting channel 303 and the collecting channel 304 are fixed side by side on the mounting frame.

[0041] The blocking unit 301 can move relative to the mounting frame to cover the top opening of the sorting channel 303 or the collecting channel 304 as needed (in the embodiment of this article, the blocking unit 301 only needs to cover the sorting channel 303). Exemplarily, the blocking unit 301 includes a blocking plate 3011, a first motor is installed on the mounting frame, one end of the blocking plate 3011 is rotatably connected to the mounting frame through a first rotating shaft, and the output shaft of the first motor is drivingly connected to the first rotating shaft.

[0042] The transfer unit 302 is movably connected to the mounting frame, and the bottom of the transfer unit 302 is open, so that the transfer unit 302 can be connected to the sorting channel 303 or the collecting channel 304. Figure 2 As shown, the mounting frame is provided with a slide rail extending in the left and right directions, and a slider is provided on the slide rail; in order to facilitate the sample tube 8 to fall from the transport structure 4 into the transfer unit 302, the top of the transfer unit 302 is also designed to be open, that is, the transfer unit 302 is in the shape of a square frame. A second motor is fixed on the mounting frame, and at least two sprocket wheels 9 are rotatably connected to the mounting frame. The sprocket wheels 9 are tensioned with chains. The transfer unit 302 is fixedly connected to the slider, and the slider is fixedly connected to one of the chain links. The second motor is in transmission connection with the sprocket wheel 9, thereby driving the sprocket wheel 9 to rotate. The mounting frame is a frame structure built according to the position and connection relationship of the components.

[0043] like Figure 3 As shown, the sample tube sorting device is further provided with a detection unit 5, which is used to detect the direction of the tube head of the sample tube 8. Exemplarily, the sorting channel 303 includes a bottom plate and side plates fixed on two opposite sides of the bottom plate, the bottom plate and the side plates together form a slideway with a "U"-shaped cross section, and the distance between the two side plates is set to be slightly larger than the diameter of the sample tube 8, so as to ensure that the sample tube 8 slides along the sorting channel 303 in a posture with the axial direction of the sample tube 8 parallel to the length direction of the sorting channel 303.

[0044] like Figure 3As shown, the detection unit 5 includes a light source 501, a sensing module and a stopper 502. The sensing module is preferably a photoelectric sensor and is mounted on a mounting frame. The light source 501 is arranged to pass through a through hole arranged on a side plate along the radial direction of the sample tube 8, and then irradiate into the sorting channel 303 and can be received by the sensing module. The stopper 502 is movably connected to the mounting frame so that one end of the stopper 502 is inserted into the sorting channel 303. When the stopper 502 is inserted into the sorting channel 303, it limits the sample tube 8 and prevents the sample tube 8 from continuing to slide down along the sorting channel 303. Specifically, the stopper 502 is rotatably connected to the mounting frame through a second rotating shaft. A fourth motor is also installed on the mounting frame, and the output shaft of the fourth motor is transmission-connected to the second rotating shaft. It should be noted that the positions of the stopper 502 and the light source 501 should be reasonably set, so that when the stopper 502 is rotated into the sorting channel 303, the light source 501 irradiates the head or tail of the sampling tube.

[0045] like Figure 3 As shown, the sample tube sorting device also includes a reversing unit 6, and the purpose of the reversing unit 6 is to adjust the directions of different sample tubes 8 to be consistent. Specifically, the reversing unit 6 has a body 601 and an adjustment module 604, wherein the body 601 is fixedly mounted on the mounting frame, and the body 601 is provided with an inlet 602 and an outlet 603, and one end of the inlet 602 is connected to the output end of the sorting channel 303. The adjustment module 604 has a cavity, and the adjustment module 604 is rotatably connected in the body 601 through a third rotating shaft, and a fifth motor is installed on the body 601, and the fifth motor is transmission-connected to the third rotating shaft to drive the adjustment module 604 to rotate. The outlet 603 is preferably designed to be in a vertical direction. The purpose of rotating the adjustment module 604 is to make its cavity communicate with the end of the inlet 602 away from the sorting channel 303, or to make its cavity communicate with the outlet 603.

[0046] In addition, the cavity is set as a through-hole structure that penetrates the regulating module 604; an outlet 603 is set on the upper and lower sides of the main body 601 respectively. The sorting device also includes a pneumatic conveying unit 7, which has an upper airway 701, a lower airway 702 and an air source module. The upper airway 701 and the lower airway 702 are respectively connected to the outlet 603. The cavity is located between the upper airway 701 and the lower airway 702 and can connect the two airways. The air source module is a conventional air supply device, and the air source module can be connected to the upper airway 701 or the lower airway 702. Adopting the above scheme, if Figure 2As shown, in the initial state, the transfer unit 302 is located above the platform 202. The sample tube 8 drops onto the platform 202 and at this time the sample tube 8 is within the transfer unit 302. If the scanner 201 scans that the sample tube 8 has been labeled, it will feedback a signal to the controller. Subsequently, the controller controls the second motor to rotate the chain, thereby causing the transfer unit 302 to move rightward together with the sample tube 8 above the sorting channel 303. At this time, the bottom of the transfer unit 302 is in communication with the sorting channel 303, and the sample tube 8 drops into the sorting channel 303.

[0047] If the sorting device does not detect the label on the sample tube 8, the controller controls the first motor to rotate the blocking plate 3011 counterclockwise until it covers the top opening of the sorting channel 303. Subsequently, it controls the transfer unit 302 to move rightward together with the sample tube 8 above the collection channel 304. At this time, the transfer unit 302 is in communication with the collection channel 304, and the sample tube 8 drops into the collection channel 304. The sorting device with this structure can automatically sort the sample tubes 8 according to requirements, greatly improving the work efficiency and accuracy.

[0048] During detection, the fourth motor drives the stopper 502 to rotate, inserting one end of the stopper 502 into the sorting channel 303. Then the sample tube 8 slides down along the sorting channel 303 until the head / tail of the sample tube 8 abuts against the stopper 502. At this time, the light beam emitted by the light source 501 irradiates on the sample tube 8. If the head of this sample tube 8 is downward (i.e., Figure 3 the state shown), at this time the light beam of the light source 501 irradiates on the non-transparent cap (i.e., the head of the sample tube 8) of the sample tube 8, and the light beam cannot pass through the cap. The induction module feedbacks this state to the controller. If the head of this sample tube 8 is upward, at this time the light beam penetrates through the transparent sample tube 8 and irradiates on the induction module. The induction module converts the optical signal into an electrical signal and feedbacks it to the controller. The detection unit 5 provides a basis for the subsequent control of the controller.

[0049] In addition, the position of the light source 501 can also be set to be higher than the tube body of the sample tube 8 and lower than the cap of the sample tube 8. Thus, during detection, if the head of this sample tube 8 is downward, when the light beam generated by the light source 501 irradiates on the cap of the sample tube 8, the light beam cannot pass through the cap. The induction module feedbacks this state to the controller. If the head of this sample tube 8 is upward, the light beam generated by the light source 501 directly passes through from above the sample tube 8 and irradiates on the induction module without having to penetrate the tube body of the sample tube 8.

[0050] During commutation, as Figure 3As shown in the figure, when the detection unit 5 detects that the cap of the sample tube 8 is facing downwards, the stopper 502 rotates counterclockwise to move away from the sorting channel 303. At this time, the sample tube 8 slides along the sorting channel 303 into the cavity of the adjustment module 604. The fifth motor drives the adjustment module 604 to rotate counterclockwise until the cavity is vertical. At this time, the cavity is respectively connected to the upper airway 701 and the lower airway 702. Taking the example that the gas source module is connected to the lower airway 702, the gas source module generates gas to push the sample tube 8 to move upwards and pass out along the upper airway 701 (conversely, if the gas source module is connected to the upper airway 701, the gas source module generates gas to push the sample tube 8 to move downwards and pass out along the lower airway 702. In practice, it is designed according to requirements).

[0051] When the detection unit 5 detects that the cap of the sample tube 8 is facing upwards, the stopper 502 rotates counterclockwise to move away from the sorting channel 303. At this time, the sample tube 8 slides along the sorting channel 303 into the cavity of the adjustment module 604. The fifth motor drives the adjustment module 604 to rotate clockwise until the cavity is vertical. At this time, the cavity is respectively connected to the upper airway 701 and the lower airway 702. The gas source module generates gas to push the sample tube 8 to move upwards and pass out along the upper airway 701.

[0052] As a preferred solution, considering that the proportion of unlabeled sample tubes 8 in practice is relatively small, as Figure 2 shown, the platform 202, the sorting channel 303 and the collection channel 304 are arranged in sequence along the moving direction of the transfer unit 302 (that is, Figure 2 arranged from left to right in the figure). In this way, the distance between the sorting channel 303 and the platform 202 is shortened, that is, the conventional working path of the transfer unit 302 (that is, from the platform 202 to the sorting channel 303) is shortened, so that a large number of labeled sample tubes 8 can enter the sorting channel 303 more quickly, and the sorting efficiency is also improved.

[0053] As a preferred solution, considering that when the sample tube 8 falls onto the platform 202, the label on it is not necessarily facing upwards, resulting in the scanner 201 being unable to identify it. As Figure 2 shown, the platform 202 is designed as a power roller group. The power roller group includes two roller shafts rotatably connected to the mounting frame and a third motor drivingly connected to the roller shafts. The two roller shafts are arranged side by side to support the sample tube 8. In addition, the third motor drives the roller shafts to rotate, thereby driving the sample tube 8 to rotate, so as to ensure that the scanner 201 can scan the label on the outer wall of the sample tube 8.

[0054] As a preferred solution, as Figure 2As shown in the figure, a set of sorting channels 303 are respectively arranged on the left and right sides of the platform 202, providing more sorting method combinations and improving the sorting efficiency and applicability of the device. For example, the sample tubes 8 that meet condition A are screened out from the leftmost sorting channel 303, those that meet condition B are screened out from the middle sorting channel 303, and those that do not meet either condition are screened out from the rightmost collection channel 304.

[0055] As a preferred solution, a second sensor and a third sensor are also installed on the mounting rack. Exemplarily, the second sensor and the third sensor are photoelectric sensors, which are respectively used to detect the positions of the stoppers 502 and the adjustment module 604, and feedback signals to the controller, making the control of the sorting device more accurate.

[0056] The present utility model also proposes a pneumatic transmission device for sample tubes, including the sample tube sorting device described in any one of the above; it outputs the sample tubes 8 through the above pneumatic conveying unit 7. Of course, other existing pneumatic conveying structures can also be used to replace the pneumatic conveying unit 7 in this embodiment, such as the conveying structures disclosed in the patents with publication numbers:

[0057] CN220033340U / CN204777590U.

[0058] This pneumatic transmission device for sample tubes saves the turnover time of blood collection tube labels and is a new type of device that is fast, safe, and accurate.
