Description

Technical Field

[0001] The utility model relates to the technical field of laboratory testing, in particular to a blood drawing and testing device. Background Art

[0002] The Laboratory Department serves as a bridge between clinical medicine and basic medicine, a comprehensive clinical medical laboratory integrating medical care, teaching, and scientific research. It is primarily responsible for collecting and analyzing biological samples such as blood, body fluids, and tissue cells from patients or those with suboptimal health. Using a variety of techniques such as biochemistry, immunology, and microbiology, it provides important clinical diagnostic evidence for studying conditions, identifying causes, tracking treatment efficacy, and estimating prognosis. The Laboratory Department not only serves patients and clinical medical departments but also undertakes medical laboratory interpretation and consultation, committed to meeting the needs of patients and clinicians. After blood draws are completed in the Laboratory Department, the collected blood samples need to be transported via a delivery device.

[0003] Chinese patent publication number CN216879044U discloses a blood drawing and testing device for a laboratory. When transporting test tubes, the device uses a battery to drive a motor, which drives a transmission frame to rotate. The transmission frame drives a transmission block to move back and forth horizontally through a wavy transmission groove, so that the transmission block drives the mounting frame and the test tube rack to move back and forth horizontally through the transmission rod. The test tube can be shaken during transportation, which can effectively prevent blood coagulation during transportation.

[0004] Although the above patent can shake the test tube to prevent blood coagulation, there is a lack of corresponding fixation between the test tube and the test tube rack, which may cause friction and collision between the test tube and the test tube rack during the shaking process, which may cause the test tube to be damaged or cracked, thereby affecting the progress of the test and possibly causing safety hazards. Utility Model Content

[0005] The utility model aims to provide a blood drawing and testing device which can improve the stability of a test tube during shaking.

[0006] To achieve the above objectives, the technical solution of the present utility model is as follows.

[0007] A blood sampling and testing device includes a housing, a placement plate disposed within the housing, connecting shafts connected to both outer surfaces of the placement plate, the ends of the connecting shafts being rotatably connected to the inner wall of the housing, and a swing mechanism capable of driving its rotation provided on the outer surface of one of the connecting shafts. Multiple test tube racks are disposed within the placement plate, two first side blocks being mounted on one side of the upper surface of the test tube racks, a slide bar being connected between the two first side blocks, and multiple groups of slides being slidably mounted on the outer surface of the slide bar, each group of slides comprising two mutually parallel slides, the opposing surfaces of the two slides being mounted with multiple clamping blocks. A clamping mechanism capable of driving the two slides to move in opposite directions is disposed on the other side of the upper surface of the test tube racks. A box cover is mounted on the top of the housing.

[0008] It can be seen that the setting of the swing mechanism can drive the placement plate to swing back and forth, thereby achieving the purpose of shaking the test tube, preventing blood coagulation, and having little impact on the test tube and the test tube rack. The setting of the clamping mechanism can drive the clamping block to clamp and fix the test tube, thereby ensuring that it remains stable during the shaking process, avoiding friction and collision with the test tube rack, which may cause damage or cracks, and has high safety.

[0009] Furthermore, the swing mechanism includes a gear sleeved on the outer surface of the connecting shaft, an electric telescopic rod is installed on the inner wall of the box, a slider is installed at the end of the telescopic end of the electric telescopic rod, a tooth plate is installed on the outer surface of the slider, and the tooth plate is meshed with the gear.

[0010] By starting the electric telescopic rod to drive the slider to reciprocate, the tooth plate can be driven to move back and forth. Since the tooth plate and the gear are engaged with each other, the placement plate can be driven to swing back and forth and the test tube can be shaken.

[0011] Furthermore, the clamping mechanism includes two second side blocks installed on the upper surface of the test tube rack, a rotating shaft is rotatably connected between the two second side blocks, the outer surface of the rotating shaft is provided with multiple groups of threads, each group of threads includes two reverse threads, and the end of the slide is installed on the thread.

[0012] Since one side of the slide is slidably mounted on the slide rod, the slide rod serves as a limiter for it. Therefore, when the shaft rotates, the slide can be driven to move along the surface of the shaft through the setting of the thread. Each set of threads includes two opposite threads, so it can drive the corresponding two slides to move inward at the same time, so that the clamping blocks on both sides are clamped on the outer surface of the test tube, playing a fixing role.

[0013] Furthermore, multiple fastening bolts are installed on the outer surfaces of both sides of the placement plate, and the fastening bolts correspond to the test tube racks.

[0014] After placing the test tube rack in the placement plate, tighten the fastening bolts so that the ends thereof are pressed tightly against the outer surface of the test tube rack, thereby fixing the test tube rack in the placement plate to prevent shaking.

[0015] Furthermore, a knob is installed at one end of the rotating shaft, and an outer surface of the knob is provided with anti-slip grooves.

[0016] The knob setting makes it easy to rotate the shaft, and the anti-slip pattern can increase the friction on its surface to reduce the chance of hand slipping.

[0017] Furthermore, a rubber pad is provided on the inner wall of the clamping block.

[0018] The provision of the rubber pad not only increases the friction force and improves the fixing effect on the test tube, but also plays a buffering role to avoid damage to the outer surface of the test tube. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention is described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-6 As shown, a blood sampling and testing device includes a housing 100, within which is disposed a placement plate 101. Connecting shafts 107 are connected to the outer surfaces of both sides of the placement plate 101, and the ends of the connecting shafts 107 are rotatably connected to the inner wall of the housing 100. A swing mechanism 200 is provided on the outer surface of one of the connecting shafts 107 to drive its rotation. Multiple test tube racks 102 are disposed within the placement plate 101. Two first side blocks 103 are mounted on one side of the upper surface of the test tube racks 102. A slide bar 104 is connected between the two first side blocks 103. Multiple sets of slides 105 are slidably mounted on the outer surfaces of the slide bars 104. Each set of slides 105 includes two parallel slides 105, and multiple clamping blocks 106 are mounted on opposing surfaces of the two slides 105. A clamping mechanism 300 is provided on the other side of the upper surface of the test tube racks 102 to drive the two slides 105 to move in opposite directions. A lid 108 is mounted on the top of the housing 100.

[0028] During use, the test tube is first inserted into the test tube rack 102, and then the two slides 105 are driven close to each other by the clamping mechanism 300, so that the clamping blocks 106 on the surface clamp the test tube, and then the box cover 108 is opened, and the test tube rack 102 containing the test tube is placed on the placement plate 101, and then the box cover 108 is closed. A lock is provided between the box cover 108 and the box body 100 to facilitate fixing the box cover 108, and then the connecting shaft 107 can be driven to rotate back and forth by the swinging mechanism 200, and the placement plate 101 is driven to swing back and forth. The test tube is shaken during the swinging of the placement plate 101, which can effectively prevent blood from coagulating during transportation. Compared with the comparative patent, the shaking amplitude of the present application is gentler, the impact force on the test tube and the test tube rack 102 is small, and the use effect is better.

[0029] Specifically, the swing mechanism 200 includes a gear 201 sleeved on the outer surface of the connecting shaft 107, an electric telescopic rod 202 is installed on the inner wall of the box body 100, and a slider 203 is installed at the end of the telescopic end of the electric telescopic rod 202. A tooth plate 204 is installed on the outer surface of the slider 203, and the tooth plate 204 is meshed with the gear 201. By starting the electric telescopic rod 202 to drive the slider 203 to reciprocate and extend, the tooth plate 204 can be driven to move back and forth. Since the tooth plate 204 and the gear 201 are meshed with each other, the purpose of driving the placement plate 101 to swing back and forth can be achieved, and the test tube can be shaken.

[0030] Specifically, the clamping mechanism 300 includes two second side blocks 301 installed on the upper surface of the test tube rack 102, and a rotating shaft 302 is rotatably connected between the two second side blocks 301. The outer surface of the rotating shaft 302 is provided with multiple groups of threads 303, each group of threads 303 includes two opposite threads 303, and the end of the slide 105 is installed on the threads 303. Since one side of the slide 105 is slidably installed on the slide bar 104, the slide bar 104 plays a limiting role thereon. Therefore, when the rotating shaft 302 rotates, the setting of the threads 303 can drive the slide 105 to move along the surface of the rotating shaft 302, and each group of threads 303 includes two opposite threads 303, so it can drive the corresponding two slides 105 to move inward at the same time, so that the clamping blocks 106 on both sides are clamped on the outer surface of the test tube, thereby playing a fixing role.

[0031] Specifically, a plurality of fastening bolts 400 are installed on the outer surfaces of both sides of the placement plate 101. The fastening bolts 400 correspond to the test tube racks 102. After the test tube rack 102 is placed in the placement plate 101, the fastening bolts 400 are screwed so that their ends are pressed against the outer surface of the test tube rack 102. Thus, the test tube rack 102 can be fixed in the placement plate 101 to prevent shaking.

[0032] Specifically, a knob 500 is installed at one end of the rotating shaft 302, and the outer surface of the knob 500 is provided with anti-slip grooves. The setting of the knob 500 facilitates the rotation of the rotating shaft 302, and the anti-slip grooves can increase the friction on its surface and reduce the occurrence of hand slippage.

[0033] Specifically, the inner wall of the clamping block 106 is provided with a rubber pad. The provision of the rubber pad not only increases the friction force and improves the fixing effect on the test tube, but also plays a buffering role to avoid damage to the outer surface of the test tube.

[0034] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention are not limited to these descriptions. For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and have the same performance or use, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
