Description

Technical Field

[0001] This application relates to the field of pneumatic pipeline logistics transmission systems and medical specimen transmission systems, and more specifically, to a passive specimen delivery device with an elastic guide ring. Background Technology

[0002] The design of specimen transport systems is an important issue in preventing specimens from colliding and vibrating with each other during transport, as specimens are transported in a sequential manner through a dedicated, sealed pipeline while maintaining a relative distance between them. After the specimens are classified and sent, the distance between them in the transport pipeline is increased. However, when the specimens enter the receiving end and exit the station, they need to slide freely out of the pipeline in the vertical pipeline section, which requires even more protection against hard impacts.

[0003] Current methods mostly rely on the specimens falling freely under their own weight into a receiving frame, and then manually arranging the sample tubes in the sample tube rack. Obviously, manual intervention is inefficient and unsafe, and the specimens entering the receiving frame may be damaged due to excessive impact force during the automatic fall of the sample tubes out of the transport channel.

[0004] Furthermore, prior art patent application number CN201910125154.6, entitled "Sample Tube Dispensing Device and Its Application," exists prior to the specimen receiving end exit control mechanism. This patent has a complex structure, employing more than three control mechanisms to address safety issues during the dispensing process. However, due to its overly complex structure, it is bound to experience a high failure rate during operation. Furthermore, the device is extremely inconvenient to maintain in the future and is unsuitable for application in specimen transport systems.

[0005] Therefore, how to mitigate the impact force on specimens falling under gravity during specimen transport and ensure that the specimen exits the tube in a state conducive to subsequent operations is a problem worthy of attention.

[0006] One objective of this invention is to provide an innovative structure and application of a specimen receiving terminal exit control mechanism to ensure that the entire process after the specimen is exited from the tube is unattended, achieving automatic loading, and operating without noise or malfunction. Utility Model Content

[0007] The main purpose of this application is to provide a passive specimen ejection device with an elastic guide ring, which allows for unattended operation throughout the entire process after ejection, achieving automatic loading and noiseless, fault-free operation.

[0008] To achieve the above objectives, in a first aspect, this application provides a passive specimen delivery device with an elastic guide ring, which is disposed between a specimen transport pipeline and a movable specimen base. It includes a passive delivery tube body and a delivery channel opened on the passive delivery tube body. The upper part of the delivery channel is connected to the specimen transport pipeline, and the lower part of the delivery channel is provided with a delivery tube. A delivery port is opened on one side of the lower part of the delivery tube, and the opening direction of the delivery port is the same as the moving direction of the movable specimen base.

[0009] The outlet is provided with a positioning structure for positioning the specimen; the positioning structure includes a clamp fixedly mounted on the outlet tube and guide rings connected to both ends of the clamp via elastic shafts, with the guide rings on both sides corresponding to the two sides of the outlet tube.

[0010] A further improvement is that a positioning protrusion is fixedly provided on the inner side of the outlet tube. The positioning protrusion and the guide rings on both sides are located on the same horizontal plane. The gap between the guide rings and the positioning protrusion is smaller than the size of the specimen head and larger than the size of the specimen tube body.

[0011] A further improvement is that the guide rings on both sides and the positioning protrusions are arranged in a triangular pattern.

[0012] A further improvement is that the guide rings on both sides and the positioning protrusions are arranged in an equilateral triangle.

[0013] A further improvement is that the guide ring is made of woven steel wire.

[0014] A further improvement is that the positioning protrusion is an arc-shaped protrusion.

[0015] A further improvement is that the movable specimen base has multiple units, which are fixedly installed and evenly distributed on the conveying device, and each movable specimen base has a positioning part on its upper part for positioning the specimen.

[0016] A further improvement is that the movable specimen base has an insertion hole, and the positioning part consists of several positioning fins distributed around the insertion hole.

[0017] A further improvement is that the height between the top of the positioning fin and the upper part of the outlet is less than the length of the specimen, and the height between the bottom of the insertion hole and the upper part of the outlet is greater than the length of the specimen.

[0018] This utility model provides a passive specimen ejection device with an elastic guide ring. Compared with the prior art, its advantages are as follows: the specimen automatically falls to the ejection port under its own gravity. By designing a guide ring, the specimen can be prevented from falling before the movable specimen base is in place. When the movable specimen base moves to directly below the ejection port, the overall structure moves down, inserting the specimen into the movable specimen base. Then, under the action of the conveying device, the specimen is automatically carried away from the ejection port, thereby realizing the passive specimen ejection action. Using this structure, the overall size is small, the manufacturing cost is low, and the operation is convenient. Attached Figure Description

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figures 1-3 As shown, a passive specimen delivery device with an elastic guide ring is disposed between a specimen transport pipe 90 and a movable specimen base. It includes a passive delivery tube body and a delivery channel opened on the passive delivery tube body. The upper part of the delivery channel is connected to the specimen transport pipe 90, and the lower part of the delivery channel is provided with a delivery tube. A delivery port 2290 is opened on one side of the lower part of the delivery tube. The opening direction of the delivery port 2290 is the same as the moving direction of the movable specimen base.

[0031] A positioning structure for positioning specimen A is provided at the outlet 2290; the positioning structure includes a clamp 229 fixedly mounted on the outlet tube and guide rings 2292 connected to both ends of the clamp 229 via elastic shafts 2294, with the guide rings 2292 on both sides corresponding to the two sides of the outlet 2290.

[0032] A further improvement is that a positioning protrusion 2295 is fixedly provided on the inner side of the outlet tube. The positioning protrusion 2295 and the guide rings 2292 on both sides are located on the same horizontal plane. The gap between the guide rings 2292 and the positioning protrusion 2295 is smaller than the size of the specimen head and larger than the size of the specimen tube. The guide rings 2292 on both sides and the positioning protrusion 2295 are distributed in an equilateral triangle. The positioning protrusion 2295 is an arc-shaped protrusion.

[0033] The outlet 2290 is designed as a fully open shape, with the maximum diameter of the opening greater than the maximum diameter of the specimen. The outlet 2290 is equipped with a set of guide rings 2292, which are inserted into two diagonally opposite elastic shafts. The guide rings 2292 are made of woven soft steel wire and are installed in a vertical arc configuration. Two rings are positioned at an angle on the same radius of the center line of the outlet 2290. The minimum diameter of the vertical arc of the guide ring 2292 and the triangular center space of the arc-shaped protrusion is greater than the diameter of the specimen's small end. The guide rings 2292 are positioned at the lowest point of the outlet 2290, forming a three-point positioning with the fixed arc-shaped protrusion inside the tube. The two guide rings 2292 in the outlet 2290 guide the specimen's small end to slide vertically down, also acting as a passive, controllable door. When the specimen base is removed from the outlet 2290, the guide rings 2292 are opened by the power of the base channel. After the base channel is removed, the guide rings 2292 automatically return to their original position.

[0034] Preferably, there are multiple movable specimen bases 40, which are fixedly arranged and evenly distributed on the conveying device. Each movable specimen base 40 has a positioning part on its upper part for positioning specimen A. The conveying device can be a conveyor belt structure, and the specific structure will not be described in detail.

[0035] The movable specimen base 40 has an insertion hole. The positioning part consists of several positioning fins 30 distributed around the insertion hole. The height between the top of the positioning fins 30 and the upper part of the outlet 2290 is less than the length of the specimen, and the height between the bottom of the insertion hole and the upper part of the outlet 2290 is greater than the length of the specimen.

[0036] Thus, when achieving passive automatic tube exit, under its own gravity, specimen A enters the guide tube exit body 20 from the transmission pipe 90. When the conveying device moves the movable specimen base directly below the tube exit 2290, specimen A falls to the tube exit 2290 through the structure of the guide tube exit body 20, causing the specimen to be inserted into the movable specimen base 40. Since the guide ring 2292 is connected to the clamp 229 through the elastic shaft 2294, when the conveying device drives the movable specimen base to continue moving, it drives specimen A to move. The guide ring 2292 is forced open, bringing specimen A out from the tube exit 2290.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
