Description

Technical Field

[0001] The utility model belongs to the field of vacuum blood collection tube conveying equipment, in particular to a vertical posture feeding device for blood collection tubes. Background Art

[0002] Hospitals conduct blood tests on numerous patients daily using vacuum blood collection tubes. These tubes need to be promptly transported to the various testing instruments in the laboratory for testing. In the past, manual transport was the only method used to deliver the tubes to the testing instruments. However, manual transport cannot guarantee timely delivery of the tubes, is prone to errors, and can cause environmental pollution and even biohazards. Consequently, devices that use compressed air to transport tubes have emerged. These devices offer the advantages of timely, fast, and efficient transport, without the need for recovery equipment. In particular, pneumatic transport systems for transporting single blood collection tubes have become increasingly popular in recent years. Traditionally, these systems place a tube in a pipe, then inject compressed air from the rear. The pressure from the air pushes the tube forward until it drops from the air into a receiving container or other instrument. Existing blood collection tubes are delivered to the pneumatic transport system via a feeding device for delivery to the corresponding testing equipment. However, this device cannot ensure that the tube enters the pneumatic transport system in a vertical position, which can affect the system's operation and is in urgent need of improvement.

DETAILED DESCRIPTION

[0022] The present invention is further described below through specific implementation methods.

[0023] Reference Figures 1 to 5 As shown, a vertical feeding device for blood collection tubes includes a mounting base 1, a lower bin 2 obliquely arranged on the mounting base 1, a feeding mechanism 4 arranged at the lower end of the lower bin 2, and an anti-tube jamming mechanism 4 arranged in the lower bin 2.

[0024] The lower hopper 2 includes a lower hopper body 21, a feed port 22 arranged at the upper end of the lower hopper body 21, a discharge section 23 arranged at the lower end of the lower hopper body 21, and a discharge port 24 arranged in the discharge section 23, wherein the discharge section 23 extends downward to the feeding mechanism 3; specifically, two guide sections 25 are formed on both sides of the lower end of the lower hopper body 21, which extend obliquely downward to the discharge section 23 to guide the blood collection tubes in the lower hopper body 21 into the discharge port 24. Furthermore, the diameter of the discharge port 24 is slightly larger than the diameter of the tube cap of the blood collection tube, so that the blood collection tubes are arranged in the discharge port 24 in a horizontal posture perpendicular to the lower hopper body 21.

[0025] The feeding mechanism 3 includes a feeding rack 31 arranged at the front end of the mounting seat 1, a feeding body 32 arranged on the feeding rack 31 and located at the lower end of the lower hopper 2, a posture correction groove 33 formed in the feeding body 32, a feeding port 34 connected to the rear end of the posture correction groove 33, a push tube assembly 35 arranged at the top of the feeding rack 31 and located on the side of the feeding body 32, a first sensor 36 arranged on the feeding body 32 for detecting whether a blood collection tube enters the posture correction groove 33, and a second sensor 37 arranged on the feeding body 32 opposite to the feeding port 34, wherein both the first sensor 36 and the second sensor 37 can be proximity sensors.

[0026] The posture correction groove 33 has an upper end that gradually bends upward from the side of the feeding body 32 to the top surface of the feeding body 32, so that the blood collection tube moving in the posture correction groove 33 gradually transitions from a horizontal posture to a vertical posture and is fed out through the feeding port 34. Specifically, the posture correction groove 33 includes a receiving section 331 that extends obliquely downward from the side of the feeding body 32 and is opposite to the lower end of the lower hopper 2, a posture correction section 332 connected to the receiving section 331 and with its upper end gradually bent upward to the top surface of the feeding body 32, and a vertical transition section 333 connected to the posture correction section 332. The vertical transition section 333 extends downward from the top surface of the feeding body 32, and the feeding port 34 is connected to the vertical transition section 333; wherein, the discharge section 23 extends downward to the feeding body 32, so that the discharge port 24 is opposite to the receiving section 331 up and down; further, the posture correction section 332 is provided with an arc-shaped protrusion 335 on the inner wall on one side close to the front end, and an adaptive arc-shaped concave surface 336 on the inner wall on one side at the rear end, so that the blood collection tube entering the posture correction section 332 can gradually transition from a horizontal posture to a vertical posture under the action of the arc-shaped protrusion 335.

[0027] The tube pushing assembly 35 includes a mounting bracket 351 arranged on the top of the feeding rack 31, a tube pushing cylinder 352 arranged on the mounting bracket 351, and a pushing block 353 arranged at the front end of the tube pushing cylinder 352, which can extend into the receiving section 331 to squeeze the blood collection tube backwards. The bottom surface of the receiving section 331 is formed with a positioning groove 334 extending downward and opposite to the lower end of the lower hopper 2. By providing the positioning groove 334, the blood collection tube falling from the discharge port 34 is first preliminarily positioned in the receiving section 331 and then squeezed and moved backwards by the pushing block 353. Specifically, the tube pushing cylinder 352 is installed obliquely on the mounting bracket 351 and opposite to the receiving section 331.

[0028] The anti-tube jamming mechanism 4 includes a swing block 41 swingably arranged at the intersection of a guide section 25 and a discharge section 23, and a swing motor 42 arranged on the lower hopper body 21 and connected to and driving the swing block 41 to swing. The swing block 41 is arranged in a non-circular shape, and the swing motor 42 can control the swing block 41 to swing back and forth at intervals, so that the blood collection tubes in the lower hopper 2 can enter the discharge port 24 in an orderly manner to prevent tube blockage.

[0029] When the blood collection tube is transported, it enters the discharge bin 1 from the feed port 11, and continues to fall into the discharge section 23 under the action of the two guide sections 25, and falls into the positioning groove 334 of the receiving section 331 through the discharge port 24. When the first sensor 36 detects that a blood collection tube is in place, the tube pushing cylinder 352 controls the pushing block 353 to move to the receiving section 331 to squeeze the blood collection tube in the positioning groove 334 outward. The blood collection tube that continues to enter is squeezed backward by the blood collection tube that has entered through the continuous reciprocating motion of the tube pushing cylinder 352. Under the continuous squeezing of the blood collection tube in front, the blood collection tube behind is gradually transitioned from a horizontal posture to a vertical posture in cooperation with the arc-shaped protrusion 335 in the posture correction section 332, and enters the air conveying transmission system through the feed port 34 in a vertical posture.

[0030] The present application limits the structure of the feeding mechanism 3 and sets a posture correction groove 33 inside it, so that the blood collection tube entering from the lower hopper 2 and moving in the posture correction groove 33 gradually transition from a horizontal posture to a vertical posture and are sent out through the feeding port 34 to ensure that the blood collection tube enters the air conveying system in a vertical posture, which is consistent with the conveying direction of the air conveying device, thereby effectively improving the efficiency of subsequent inspections.

[0031] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of implementation of the present invention. In other words, equivalent changes and modifications made according to the scope of the patent application and the contents of the specification of the present invention should still fall within the scope of the present patent.
