Description

Technical Field

[0001] The invention relates to the medical field, and in particular to an automatic labeling and directional dispensing device for sample tubes. Background Art

[0002] In traditional blood collection activities, the patient's name, barcode, blood test items and other information are usually handwritten by medical staff on the label, or a self-adhesive barcode containing the patient's information is pre-printed and then manually pasted on the disposable sample tube. Not only is the work intensity high and the efficiency low, but it is also easy to cause the patient's information to be unclear due to skewed attachment, wrinkles, etc., resulting in the inconsistency between the label and the sample tube when the medical staff reads the label information. The inconsistent labeling makes the subsequent testing equipment unable to recognize it. If misdiagnosis occurs, it will cause medical accidents and cause great harm. To solve this problem, more and more medical institutions are using automatic sample tube preparation equipment to help automatically select sample tubes, print and paste labels, and then distribute them to medical staff for sampling.

[0003] Common automatic labeling and dispensing devices of sample tube automatic preparation equipment all use vertical labeling to save space. This labeling mode generally requires sample tubes to be oriented vertically upward, which makes it inconvenient to add sample tubes in a fixed direction in the tube bin. Some horizontal labeling methods can achieve two-way labeling and two-way dispensing of sample tubes, but they waste a lot of space, resulting in a small space left for the tube bin or the finished device being too large.

[0019] See also Figure 1-3The present invention provides a technical solution: an automatic labeling and directional dispensing device for sample tubes, comprising a rack 1-2 installed inside a sample tube preparation device, the automatic labeling and directional dispensing device for sample tubes is fixedly installed inside the sample tube device through the rack 1-2, a drum working chamber 1 is fixed on the rack 1-2, the drum working chamber 1 is composed of two groups of symmetrically arranged arc plates 1-1, the upper part of the two groups of arc plates 1-1 is spaced to form an upper slot 1-3-1, and the lower part is spaced to form a lower slot 1-3-2, and the two groups of arc plates 1-1 are also rotatably provided with an arc door 5-2; a rotating drum 2-3 is rotatably provided in the drum working chamber 1, and tube clamping grooves 2-4-1 are symmetrically provided at both ends of the rotating drum 2-3 in the length direction; one side of the rack 1-2 is provided There is a sample tube conveying track 6-1, wherein the sample tube conveying track 6-1 conveys the sample tube by belt conveying. A track motor 6-2 for driving the belt to rotate is arranged on the frame 1-2. One end of the sample tube conveying track 6-1 is located in the lower slot 1-3-2. The frame 1-2 is provided with side baffles 6-3 on both sides of the belt to ensure that the sample tube enters the lower slot 1-3-2 in a vertical state. The rotating drum wheel 2-3 is rotatably arranged inside the drum working chamber 1. One end of the sample conveying track is used to connect with the cabin discharge port of the sample tube equipment. After the sample tube is conveyed to the lower slot 1-3-2, the rotating drum wheel 2-3 rotates and brings the sample tube at the lower slot 1-3-2 to the upper slot 1-3-1 through the tube clamping slot 2-4-1 for labeling. The frame 1-2 is provided with a rotary labeling mechanism 4 at the position of the upper slot 1-3-1, and the rotary labeling mechanism 4 includes a fixed pasting rod 4-1, a rotating roller 4-2, and a light-sensitive sensing mechanism 4-5. The fixed pasting rod 4-1 and the rotating roller 4-2 are both rotatably arranged above the upper slot 1-3-1. After the sample tube is transported to the upper slot 1-3-1, the fixed pasting rod and the rotating roller 4-2 are attached to the sample tube and rotate together, so that the label is attached to the sample tube (wherein the label is printed by a printing device and transported to the position of the upper slot 1-3-1, and the printing device is the prior art). The light-sensitive sensing mechanism 4-5 is arranged in the middle of the rotating roller 4-2. The frame 1-2 is also provided with a limiting mechanism 4-4 for limiting the sample tube to be in the label pasting position, wherein the limiting mechanism 4-4 is used to limit the sample tube to the middle position, so that the sample tube is in the label pasting position during printing.

[0020] Specifically, the limiting mechanism 4-4 includes a limiting rod 4-4-1, a guide rod 4-4-2 and a limiting slide 4-4-3. The limiting slides 4-4-3 are symmetrically arranged on both sides of the limiting rod 4-4-1. The limiting slide 4-4-3 is connected to the limiting rod 4-4-1 through a sliding ring 4-4-5 and is slidably arranged on the limiting rod 4-4-1 and the guide rod 4-4-2 through the sliding ring 4-4-5. The frame 1-2 is also provided with a limiting motor 4-4-4 for driving the two groups of limiting slides 4-4-3 to slide toward or away from each other. One end of the limiting slide 4-4-3 is connected to the limiting rod 4-4-1, and the other end extends into the upper slot 1-3-1. The limiting slide 4-4-3 is initially located on both sides of the rotating drum 2-3 and will not limit the rotation of the rotating drum 2-3 in the drum working chamber 1. After the rotating drum 2-3 rotates to a position where a group of tube clamping grooves 2-4-1 are located in the upper slot 1-3-1, the limiting slides 4-4-3 on both sides slide toward the side close to each other to position the sample tube so that the sample tube is located in the middle position.

[0021] Specifically, two groups of limit motors 4-4-4 are arranged, and pulleys 4-4-7 are rotatably arranged on both sides of the frame 1-2. A driving belt 4-4-6 is connected between the output ends of the two groups of limit motors 4-4-4 and the pulleys 4-4-7 respectively. One end of the limit slide 4-4-3 is fixedly connected to the transmission belt. The movement of the transmission belt will drive the limit slide 4-4-3 to slide on the limit rod 4-4-1.

[0022] Specifically, a first driven silicone roller 4-1-1 is provided in the middle of the fixed pasting rod 4-1, a silicone ring 4-2-1 is provided in the middle of the rotating roller 4-2, and a roller motor 4-3 is provided on the frame 1-2. The roller motor 4-3 is connected to the rotating roller 4-2 by a belt. The roller motor 4-3 drives the rotating roller 4-2 to rotate, and the first driven silicone roller 4-1-1 and the silicone ring 4-2-1 jointly drive the sample tube to be labeled. The materials of the first driven silicone roller 4-1-1 and the silicone ring 4-2-1 can avoid damage to the sample tube and increase the friction on the sample tube.

[0023] Specifically, the photosensor mechanism 4-5 includes a metal fixing rod 4-5-2 and a photosensor 4-5-1. The metal fixing rod 4-5-2 is arranged in parallel with the limit rod 4-4-1. The photosensor 4-5-1 is arranged in the middle of the fixing rod. The sensing head of the photosensor 4-5-1 is directly opposite to the position of the upper slot 1-3-1. The rear end of the photosensor 4-5-1 is connected to an amplifier 4-5-3. The photosensor 4-5-1 can sense whether a sample tube enters the upper slot 1-3-1, and provide a signal to the printer to determine whether to print and output a label.

[0024] Specifically, there are multiple groups of rotating drum wheels 2-3 and they are all aligned. The rotating drum wheels 2-3 are coaxially arranged with the drum working chamber 1 and have a gap with the inner wall of the arc plate 1-1. A fourth motor is arranged on the frame 1-2 to drive the rotating drum wheels 2-3 to rotate, wherein the spacing between two adjacent groups of rotating drum wheels 2-3 is smaller than the length of the sample tube, thereby ensuring that the sample tube can be transferred.

[0025] In order to lift the sample tube when it enters the upper groove 1-3-1 and make the sample tube fit the first driven silicone roller 4-1-1 and the silicone ring 4-2-1, the frame 1-2 is located on the outer side of the arc plate 1-1 and is provided with a positioning and pushing mechanism 3, the positioning and pushing mechanism 3 includes two groups of metal pushing sheets 3-1 forming an open hook angle toward the working chamber 1 of the drum, the positioning and pushing mechanism 3 is composed of two metal pushing sheets 3-1 and a metal rod 3-4 forming an open hook angle toward the working chamber 1 of the drum, one end of the metal pushing sheet 3-1 is riveted to the metal rod 3-4, one end of the metal rod 3-4 is suspended, and the other end is fixedly connected to the pushing motor 3-3, and the pushing motor 3-3 can be started to drive the metal rod 3-4 to rotate, thereby driving the metal pushing sheet 3-1 to rotate into the working chamber 1 of the drum, and the working chamber of the drum The arc surface of 1 is opposite to the metal pushing sheet 3-1 of the positioning pushing mechanism 3, and an arc notch 1-4 is respectively opened for the metal pushing sheet 3-1 to rotate into the drum working chamber 1. The metal pushing sheet 3-1 can rotate through the arc notch 1-4 from the outside of the drum working chamber 1 to the inside of the chamber. A gap is left between the two groups of metal pushing sheets 3-1. The two groups of metal pushing sheets 3-1 can respectively pass through the gap between the two adjacent groups of rotating drum wheels 2-3 and reach the position of the upper notch 1-3-1. The lower ends of the metal pushing sheets 3-1 are respectively equipped with second driven silicone rollers 3-2. The metal pushing sheets 3-1 rotate and drive the second driven silicone rollers 3-2 to move into the upper notch 1-3-1 to lift the sample tube, so that the sample tube fits the first driven silicone roller 4-1-1 and the silicone ring 4-2-1.

[0026] Specifically, 5 is symmetrically arranged on the left and right sides of the drum working chamber 1, 5 includes a door opening rod 5-8, a guide bar 5-7 and an arc door motor 5-4 for driving the door opening rod 5-8 to rotate, and guide grooves 5-9 for sliding the door opening rod 5-8 are arranged on both sides of the frame 1-2. The connecting rod is fixed to the bottom end of the arc door 5-2. The frame 1-2 is provided with a sample tube discharge slide 5-6 below the arc door 5-2. After the sample tube is labeled, it can be transferred to the arc doors 5-2 on both sides by rotating the drum wheel 2-3. Position, open the arc door 5-2 through the arc door motor 5-4, and the sample tube in the tube clamping slot 2-4-1 will slide out from the sample tube discharge slide 5-6, and a collection box can be placed at the bottom of the sample tube discharge slide 5-6 to collect the sample tube. It should be noted that: the arc door 5-2 is located in the middle and lower position of the arc plate 1-1, and the tube clamping slot 2-4-1 of the rotating drum 2-3 is opposite to the arc door 5-2, and the sample tube on the rotating drum 2-3 will automatically fall out.

[0027] Specifically, observation holes are provided on the surfaces of the arc plate 1 - 1 and the arc door 5 - 2 of the drum working chamber 1 , so as to facilitate observation of the internal conditions of the equipment.

[0028] When the device is in use, the sample tube falls from the tube storage bin (internal structure of the sample tube preparation device) into the sample tube track, and the sample tube track transports the sample tube to the lower slot 1-3-2 (a group of tube clamping slots 2-4-1 of the rotating drum 2-3 is also located at the lower slot 1-3-2 position in the initial state), and the sample tube also enters the tube clamping slot 2-4-1 of the rotating drum 2-3. The rotating drum 2-3, driven by the drum motor 2-2, moves upward with the sample tube through the tube clamping slot 2-4-1 along the inner wall of the drum working chamber 1 until the sample tube is brought to The rotating drum 2-3 stops after reaching the upper groove 1-3-1. At this time, the tube clamping groove 2-4-1 under the rotating drum 2-3 is located at the lower groove 1-3-2 position, and the sample tube can be continuously transported to the lower groove 1-3-2 (i.e. the lower groove 1-3-2 position of the rotating drum 2-3) through the sample tube track. After the sample tube is brought to the upper groove 1-3-1 position by the rotating drum 2-3, the limiting slide 4-4-3 of the limiting mechanism 4-4 is driven by the limiting motor 4-4-4 to slide from the outside to the inside until it contacts the head and tail ends of the sample tube, so that the sample tube is located in the middle position. Driven by the push motor 3-3, the positioning push mechanism 3 moves from outside to inside through the arc-shaped notch 1-4 on the surface of the roller working chamber 1. The second driven silicone roller 3-2 at the end of the metal push plate 3-1 touches the sample tube from below and lifts it from the upper notch 1-3-1, moves it out of the roller working chamber 1 and into the upper sample tube pasting position. After the sample tube touches the first driven silicone roller 4-1-1 of the fixed pasting rod 4-1 of the rotating labeling mechanism 4 and the silicone ring 4-2-1 of the rotating roller shaft 4-2, the fixed pasting rod 4-1, the rotating roller shaft 4-2, and the rollers of the metal push plate 3-1 embrace the sample tube from the top, middle and bottom planes. The rotating roller 4-2 of the rotating labeling mechanism 4 starts to rotate under the drive of the roller motor 4-3, and the sample tube is driven to rotate between the first driven silicone roller 4-1-1 of the fixed pasting rod 4-1, the silicone fixing ring of the rotating roller 4-2, and the second driven silicone roller 3-2 of the metal pushing sheet 3-1. The photosensitive sensor 4-5-1 starts to find a suitable pasting position for the sample tube. The printing module of the sample tube preparation system prints the label paper and sends it to the pasting position through the label guide plate. The glued surface of the label contacts the sample tube. Through the rotation of the sample tube and the extrusion of the silicone contact surface, the label is well attached to the surface of the sample tube.

[0029] After the sample tube is labeled, the rotating roller 4-2 of the rotating labeling mechanism 4 stops rotating, and the limiting slide 4-4-3 of the limiting mechanism 4-4 slides from the inside to the outside under the drive of the limiting motor 4-4-4, away from the head and tail ends of the sample tube. Under the drive of the pushing motor 3-3, the second driven silicone roller 3-2 of the two metal pushing plates 3-1 of the positioning pushing mechanism 3 releases the squeeze on the sample tube, and the metal pushing plate 3-1 retreats downward from the bottom of the sample tube pasting position into the drum working chamber 1, and the sample tube falls back to the tube clamping groove 2-4-1 of the rotating drum wheel 2-3, and the metal pushing plate 3-1 continues to move outward from the inside of the drum working chamber 1 through the arc-shaped notch 1-4 on the surface of the drum working chamber 1, and retreats to the standby position.

[0030] The sample tube printing and labeling module rotates left or right by degrees under the drive of the drum motor 2-2 according to the direction instruction of the upper system. The sample tube embedded in the tube clamping slot 2-4-1 of the rotating drum wheel 2-3 rotates to the lower left or lower right by degrees along the inner wall of the drum working chamber 1 under the drive of the rotating drum wheel 2-3 and stops. The sample tube with the label in the slot slides to the inner wall of the arc door 5-2. According to the instruction of the upper system in the same direction, the arc door motor 5-4 on the left or right side of the drum working chamber 1 drives the door opening rod 5-8 to lift the arc door 5-2 on the corresponding side upward along the outer wall surface of the drum working chamber 1 to expose the door opening. Due to the loss of the support of the inner wall of the arc door 5-2, the labeled sample tube slides downward and outward from the tube clamping slot 2-4-1 to the sample tube discharge landslide under the action of gravity, and rolls down along the discharge landslide to the external tray.
