Technical Field

[0001] The utility model relates to a device for storing and supplying test tubes. Background Art

[0002] Before collecting blood from patients, medical staff need to manually find the corresponding blood collection tube and manually stick the corresponding barcode of the patient to facilitate subsequent hospital management and the patient's acquisition of their own report. In order to reduce the time for medical staff to draw blood, shorten the waiting time for patients to have blood drawn, improve the efficiency of blood collection, ensure the standardization of labeling and improve the accuracy of labeling, people have set up automatic labeling equipment. However, the current automatic labeling equipment is often large in size, and medical staff need to confirm the direction of the test tube when inserting it. In order to further improve the space utilization and work efficiency of automatic labeling equipment, there is an urgent need for a device to store and supply test tubes. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a device for storing and supplying test tubes, which improves the space utilization and working efficiency of automatic labeling equipment.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A device for storing and supplying test tubes, comprising a cavity unit, a driving unit, a lower tube handling unit, an upper tube handling unit, a tube outlet unit, and a detection unit, wherein the driving unit, the lower tube handling unit, and the detection unit are mounted on the cavity unit, and the driving unit drives the lower tube handling unit, the upper tube handling unit, and the tube outlet unit to operate;

[0006] The driving unit includes a driving motor, a driving wheel, a round belt and a lower pipe processing active block. The driving motor is installed on the cavity unit. The driving motor has output shafts on both sides. The driving wheel is installed on the output shaft of the driving motor mounting surface. One end of the round belt is sleeved on the driving wheel. The lower pipe processing active block is installed on the output shaft on the other side of the driving motor. The lower pipe processing active block is oval in shape.

[0007] The lower pipe unit includes a fixed shaft and a lower pipe driven block, the fixed shaft is axially fixed to the left and right plates of the cavity unit, the lower pipe driven block is inserted into the fixed shaft and can rotate freely, and the left and right positions of the lower pipe driven block are limited, and the lower pipe driven block is supported by the lower pipe active block;

[0008] The upper pipe-handling unit includes a pipe-handling driven wheel, a pipe-handling shaft, a small pipe-handling wheel, a large pipe-handling wheel, a sensor baffle and a tension spring. The other end of the round belt is sleeved on the pipe-handling driven wheel. The pipe-handling shaft passes through the bearings on the left plate and the right plate of the cavity unit. The pipe-handling driven wheel, the small pipe-handling wheel and the large pipe-handling wheel are fixed on the pipe-handling shaft. The sensor baffle is sleeved on the pipe-handling shaft. One end of the tension spring is fixed on the sensor baffle.

[0009] The tube outlet unit includes a tube outlet driven wheel, a tube outlet shaft, and a tube outlet wheel. The tube outlet shaft passes through bearings on the left and right plates of the cavity unit. The tube outlet driven wheel and the tube outlet wheel are fixed on the tube outlet shaft. The tube outlet wheel is provided with a groove for accommodating a test tube.

[0010] The sensor baffle of the upper tube handling unit is used to detect whether there is a test tube in the groove of the tube outlet wheel. As the tube outlet wheel rotates, the test tube in the groove of the tube outlet wheel will move the sensor baffle; the movement of the sensor baffle causes the detection unit to have a triggered state and a non-triggered state. When the test tube is not in contact with the sensor baffle, the sensor baffle does not trigger the detection unit under the action of the tension spring; when the test tube is in contact with the sensor baffle, the sensor baffle triggers the detection unit after contacting the set position.

[0011] Furthermore, the round belt of the driving unit is an elastic round belt to prevent the test tube from getting stuck in the cavity and causing damage to the device.

[0012] Furthermore, the tube sorting wheel is set with two diameters and is designed with a special-shaped outer contour and a mirrored arrangement to adapt to the different diameters of the tube caps and tube bodies in the test tubes, improve the tube sorting efficiency, and realize that there is no need to confirm the direction when inserting the test tubes.

[0013] Furthermore, in the upper pipe management unit, a tension spring connects the sensor baffle to the front plate to prevent the sensor baffle from failing to fall back and causing device failure.

[0014] Preferably, the cavity unit includes a rear plate, a left plate, a right plate, a front plate and a bottom plate, and the left plate and the front plate, the front plate and the right plate, the right plate and the rear plate, the right plate and the bottom plate, and the bottom plate and the left plate are connected by fasteners to form a cavity.

[0015] The device also includes a long and short tube adapter unit, which includes a first short tube plate and a second short tube plate. When the cavity unit is not installed with the long and short tube adapter unit, the cavity unit can accommodate long-sized test tubes; when the cavity unit is installed with the long and short tube adapter unit, the space of the cavity unit is compressed, and long-sized test tubes cannot be placed in, but short-sized test tubes can be placed in.

[0016] The technical concept of this utility model is to achieve a smaller device with the same loading capacity by adopting a more compact structural layout and using fewer parts to complete its functions. The unique outer contours of the tube unscrambling wheels and the mirrored arrangement of the wheels with different diameters eliminate the need to confirm the orientation when inserting test tubes. The disordered placement of the test tubes makes the arrangement of the test tubes within the device more compact, further improving space utilization and work efficiency.

[0017] The beneficial effects of the utility model are mainly manifested in: improving the space utilization and working efficiency of the automatic labeling equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Reference Figures 1 to 6 A device for storing and supplying test tubes includes a cavity unit 1, a drive unit 2, a lower tube handling unit 3, an upper tube handling unit 4, a tube outlet unit 5, a detection unit 6, and a long-short tube adapter unit 7. When the cavity unit 1 is not equipped with the long-short tube adapter unit 7, the cavity unit 1 can accommodate long test tubes 8. When the long-short tube adapter unit 7 is installed in the cavity unit 1, the space in the cavity unit 1 is compressed, and long test tubes 8 cannot be placed therein, but short test tubes 8 can be placed therein.

[0026] Reference Figure 2 The rear plate 11, the left plate 12, the right plate 13, the front plate 14 and the bottom plate 15, the left plate and the front plate, the front plate and the right plate, the right plate and the rear plate, the right plate and the bottom plate, and the bottom plate and the left plate are connected by fasteners to form a cavity unit 1.

[0027] Reference Figure 1 、 Figure 3 and Figure 4(A), the drive unit 2, lower pipe handling unit 3, upper pipe handling unit 4, pipe outlet unit 5, and detection unit 6 are assembled in a specific position on the cavity unit 1. The drive motor 21 in the drive unit 1 is preferably a dual-output shaft motor, and the drive wheel 22 and the lower pipe handling active block 24 are installed on both sides of the drive motor output shaft. The drive wheel 22 drives the upper pipe handling unit 4 and pipe outlet unit 5 through two round belts 23, and drives the lower pipe handling driven block 33 in the lower pipe handling unit 3 through the lower pipe handling active block 24.

[0028] Reference Figure 4 (A) and Figure 4 (B), the lower pipe follower block 33 is inserted into the lower pipe shaft 31, and limit positions are made on the left and right sides of the lower pipe follower block 33 to ensure that the lower pipe follower block 33 can only make circular motion, and the lower pipe follower block 33 is supported by the lower pipe active block 24. Preferably, the bottom edge length of the lower pipe follower block 33 is designed as follows: no matter what the relative position of the lower pipe follower block 33 and the lower pipe active block 24 is, the bottom edge of the lower pipe follower block 33 is always above the lower pipe active block 24, so as to ensure that when the drive motor 21 rotates forward and reverse, the lower pipe follower block 33 is always above the lower pipe active block 24 to avoid jamming. The lower pipe active block 24 is designed to be elliptical, and a circular arc protrusion is made at the vertex of the long side of the ellipse. When it reaches Figure 4 In the (B) state, the lower tube-arranging active block 24 pushes the lower tube-arranging driven block 33 to the top of the bottom plate 15, and lifts the test tube 8, thereby achieving the tube-arranging effect.

[0029] Reference Figure 5 The small tube-arranging wheel 41 and the large tube-arranging wheel 42 are both designed with protrusions on all sides. When they come into contact with the test tubes, they will lift the test tubes and achieve the effect of tube arrangement. In further detail, the two tube-arranging wheels are arranged in a mirror image, so that the direction of the test tubes does not need to be confirmed when inserting them.

[0030] Reference Figure 6 The tube outlet unit 5 includes a tube outlet driven wheel, a tube outlet shaft and a tube outlet wheel 51. The tube outlet shaft passes through the bearings on the left and right plates of the cavity unit, is axially fixed, and rotates circumferentially. The tube outlet driven wheel and the tube outlet wheel 51 are fixed on the tube outlet shaft. The tube outlet wheel 51 is provided with a groove for accommodating a test tube.

[0031] The sensor baffle 43 of the upper tube handling unit 4 is used to detect whether there is a test tube in the groove of the tube outlet wheel 51. As the tube outlet wheel 51 rotates, the test tube in the groove of the tube outlet wheel 51 will move the sensor baffle 43. The movement of the sensor baffle causes the detection unit to have a triggered state and a non-triggered state. When the test tube is not in contact with the sensor baffle, the sensor baffle does not trigger the detection unit under the action of the tension spring; when the test tube is in contact with the sensor baffle and reaches a set position, the sensor baffle triggers the detection unit.

[0032] It is further explained that when the test tube in the tube outlet unit and the sensor baffle of the upper tube processing unit change from non-contact to contact and then to non-contact, the detection unit may change from triggered to not triggered and then to not triggered.

[0033] When the tube-discharging wheel 51 rotates to a certain position, the test tube slides from the bottom plate 5 into the groove of the tube-discharging wheel 51 due to gravity. At this time, the sensor baffle 43 has not reached the position of the trigger detection unit 6 under the action of the tension spring 44. The tube-discharging wheel 51 continues to rotate. During this period, the test tube contacts the sensor baffle 43, causing the sensor baffle 43 to gradually reach the position of the trigger detection unit 6. At this time, the tube-discharging wheel 51 stops rotating and is considered to be in a state of preparation for tube discharging. When the tube-discharging instruction is received, the tube-discharging wheel 51 continues to rotate. The test tube will no longer contact the sensor baffle 43 and will separate from the tube-discharging wheel 51 under the action of weight. At the same time, the sensor baffle 43 leaves the position of the trigger detection unit 6 under the action of the tension spring 44. The tube is discharged successfully, and the test tube supply process is completed once.

[0034] The device for storing and supplying test tubes in this embodiment has a more compact structure and layout, uses fewer parts, can store test tubes in a disorderly manner, improves the space utilization and work efficiency of the automatic labeling equipment, and has high market application and promotion value.

[0035] The embodiments of this specification are merely examples of implementations of the utility model and are provided for illustrative purposes only. The scope of protection of this utility model should not be considered limited to the specific forms described in these embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by ordinary technicians in this field based on the concept of this utility model.
