Description

Technical Field

[0001] This utility model relates to the field of blood collection tube rack technology, specifically a blood collection device. Background Technology

[0002] Blood collection is the process of obtaining a blood sample from the human body. During this process, blood collection tubes are used for preservation. These tubes mainly consist of a tube body and a cap. The tube body is typically made of transparent glass or plastic, making it easy to observe the amount, color, and other characteristics of the blood. Plastic tubes are lightweight, less prone to breakage, and safer and more convenient to transport and use. The caps come in various colors, with different colors indicating different additives contained within for specific testing purposes. After blood collection, the tubes must be placed on a test tube rack for storage or movement.

[0003] The aforementioned devices lack the structure of a single-row detachable test tube rack and rapid label scanning for observation. As a result, existing test tube racks are mostly set up in multiple rows and columns. During subsequent scanning and inspection, the labels on the test tubes are often obscured because the test tubes are completely inside the rack or multiple rows and columns of test tubes are obscured. Each test tube must be removed from the rack, scanned, and then put back, which is cumbersome and inefficient, and patients also have long waiting times. Based on the shortcomings of existing technology, this utility model designs a blood collection device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a blood collection device that features a detachable single-row test tube rack and quick label scanning for observation.

[0005] This utility model provides the following technical solution: a blood collection device, including a tube rack, a base provided on the lower surface of the tube rack, a blood collection tube provided inside the tube rack, a label paper fixedly connected to the blood collection tube, and a limiting mechanism provided inside the tube rack to facilitate fixing blood collection tubes of different sizes and observing the label paper.

[0006] The limiting mechanism includes a test tube trough, an observation trough, a second slot, a connector, a spring, and a clamping piece. The test tube trough is located on the upper surface of the test tube trough. The observation trough extends through the front and rear side walls of the test tube trough. The second slot is located at the top of the inner wall of the test tube trough and on the upper surface of the tube rack. The connector is fixedly inserted into the interior of the second slot. The spring is fixedly connected to the lower surface of the connector. The clamping piece is fixedly connected to the bottom end of the spring.

[0007] As a preferred technical solution of this utility model, a first slot is provided on the upper surface of the base, a side frame is fixedly connected to one side of the base, a round-headed limiting rod is slidably inserted through the side frame, a baffle is fixedly connected to the round-headed limiting rod, a spring is sleeved on the round-headed limiting rod, and a round groove is provided on one side of the tube frame.

[0008] As a preferred embodiment of this utility model, the blood collection tube is inserted into the inside of the test tube slot, and the label is placed on the inside of the observation slot.

[0009] As a preferred embodiment of this invention, the clamping plate is disposed on the side wall of the blood collection tube.

[0010] As a preferred embodiment of this utility model, the tube rack is inserted into the inside of the first slot, and the inner end of the round-headed limiting rod is slidably engaged with the round groove.

[0011] As a preferred embodiment of this utility model, the baffle is slidably connected inside the side frame.

[0012] In a preferred embodiment of this invention, the two ends of the spring are fixedly connected to the baffle and the side frame, respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This blood collection device involves placing the blood collection tube above the test tube slot after blood collection is completed using the blood collection tube. The tube is then rotated to align the label with the observation slot. The tube is then moved downwards and inserted into the test tube slot. During insertion, the bottom of the tube contacts the inner side of a spring clip, which then bends and deforms, allowing the tube to be easily inserted. Once the tube is inserted to the bottom of the slot, a clamping piece fixedly connected to the bottom of the spring clip contacts the side wall of the tube, using the spring's elasticity to clamp and fix the tube. The label on the side wall of the tube is also inside the observation slot, allowing for direct scanning or observation. This device facilitates the fixation of the test tube.

[0015] 2. This blood collection device releases the tube rack by pulling the round-headed limiting rod outwards to remove it from the round groove. The moving round-headed limiting rod compresses the spring through the baffle. After the tube rack is pulled out of the first slot, the round-headed limiting rod is released, causing the spring to rebound and push the baffle and round-headed limiting rod back to their original positions. At this point, the tube rack can be held and the labels on the blood collection tubes can be scanned from the observation slot. After scanning a single row of blood collection tubes, the tube rack can be directly inserted into the first slot. The bottom of the tube rack can be squeezed to move the inner end of the round-headed limiting rod outwards, smoothly inserting and locking into the round groove. Finally, the same steps can be repeated to scan the labels on other rows of blood collection tubes. This device facilitates quick scanning of single rows of blood collection tubes.

By setting up a second slot 303, a plug-in piece 304 and a spring piece 305, with a clamping piece 306 fixedly connected to the bottom end of the spring piece 305, it is convenient to use the elastic force of the spring piece 305 to push the clamping piece 306 inward to clamp and fix blood collection test tubes 101 of different sizes.

[0025] Please see Figure 3 The upper surface of the base 2 is provided with a first slot 201. A side frame 202 is fixedly connected to one side of the base 2. A round-headed limiting rod 203 is slidably inserted through the side frame 202. A baffle 204 is fixedly connected to the round-headed limiting rod 203. A spring 205 is sleeved on the round-headed limiting rod 203. A round groove 206 is provided on one side of the tube frame 1. The tube frame 1 is inserted into the first slot 201. The inner end of the round-headed limiting rod 203 is slidably engaged with the round groove 206. The baffle 204 is slidably connected to the inside of the side frame 202. The two ends of the spring 205 are fixedly connected to the baffle 204 and the side frame 202, respectively.

[0026] The first slot 201 is provided to allow the pipe rack 1 to be inserted into the base 2 for fixation. The round head limiting rod 203 and the round groove 206 are provided to limit the pipe rack 1 inserted into the first slot 201, preventing the pipe rack 1 from slipping out of the first slot 201 when it is hit by other collisions or tipped over. The baffle 204 and the spring 205 are provided to ensure that the round head limiting rod 203 can always be in contact with the round groove 206 to lock the pipe rack 1 when it is not controlled by external force.

[0027] Working principle: When a blood collection device is used, in the initial state, the tube rack 1 is first inserted into the first slot 201 opened on the upper surface of the base 2. The round-headed limiting rod 203, which is slidably inserted through the side frame 202 fixedly connected to one side of the base 2, is connected to the round groove 206 opened on the side wall of the tube rack 1, so as to limit the tube rack 1 inserted into the first slot 201. At the same time, a test tube groove 301 and an observation groove 302 are opened inside the tube rack 1. The second slot 303 opened on the side wall of the observation groove 302 is inserted with a connecting piece 304 and a spring piece 305. The bottom end of the spring piece 305 is fixedly connected with a clamping piece 306, which contacts the blood collection test tube 101, so as to fix test tubes of different sizes.

[0028] When it is necessary to fix the test tube, first, after the blood collection tube 101 has finished collecting blood, place the blood collection tube 101 above the test tube slot 301, and then rotate the blood collection tube 101 so that the label 102 is vertically aligned with the observation slot 302. At this time, the blood collection tube 101 can be moved downward and inserted into the test tube slot 301. During the insertion process, the bottom end of the blood collection tube 101 will contact the inner side of the spring 305, and then the spring 305 will bend and deform by being squeezed outward, so that... The blood collection tube 101 can be smoothly inserted into the test tube slot 301. After the blood collection tube 101 is inserted to the bottom of the test tube slot 301, the clamping piece 306 fixedly connected to the bottom end of the spring piece 305 will contact the side wall of the blood collection tube 101, and the spring force of the spring piece 305 can be used to clamp and fix the blood collection tube 101. At this time, the label paper 102 on the side wall of the blood collection tube 101 is also inside the observation slot 302, and can be directly scanned or observed. This device is convenient for fixing the test tube.

[0029] When it is necessary to quickly scan the single-row blood collection tube 101, first pull the round-headed limiting rod 203 outward to remove it from the circular groove 206 and release the locking of the tube rack 1. The moving round-headed limiting rod 203 compresses the spring 205 through the baffle 204. After the tube rack 1 is pulled out of the first slot 201, release the round-headed limiting rod 203 so that the spring 205 rebounds and pushes the baffle 204 and the round-headed limiting rod 203 to reset. At this time, the tube rack 1 can be held and pulled out of the observation slot 3. At point 02, the labels 102 attached to the blood collection tubes 101 are scanned. After scanning of a single row of blood collection tubes 101, the tube rack 1 is directly inserted into the first slot 201. The inner end of the round head limiting rod 203 at the bottom of the tube rack 1 can be squeezed outward to smoothly insert and lock into the round groove 206 for locking. Finally, follow the same steps to scan the labels 102 on other rows of blood collection tubes 101. This device facilitates quick scanning of single rows of blood collection tubes 101.
