Medical blood sampling device

Abstract

This utility model relates to the field of blood sampling technology, specifically to a medical blood sampling device, comprising: a base plate, on which a support frame is fixedly mounted; and a driving assembly, which includes a rotating wheel disposed above the base plate and on one side of the support frame, with multiple collection cylinders slidably mounted in a circumferential array inside the rotating wheel. Through the design of the collection assembly, during blood sampling after a patient's finger is punctured, a rubber column can be used to squeeze and rub the sides of the fingertip, accelerating the flow of blood from the puncture point and dripping blood containing tissue fluid. The roller design allows for the enlargement of the roller diameter after the first drop of blood containing tissue fluid drips from the puncture point, lifting the finger and facilitating subsequent sampling. The dripped blood can be collected through the collection cylinders, preventing it from dripping to other places and causing inconvenience for subsequent cleaning.

Description

Technical Field

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

[0002] Blood samples from diabetic patients are typically used to test blood glucose levels and assess diabetes control. Blood glucose monitoring is an important part of diabetes management, helping doctors determine whether a patient's blood glucose control is ideal, and also helping patients understand their blood glucose fluctuations.

[0003] Blood collection often involves pricking a finger to obtain a blood sample, but this process can easily result in the collection of tissue fluid (interstitial fluid). The presence of this tissue fluid can dilute the glucose concentration in the blood, thus affecting the accuracy of blood glucose measurements. However, existing blood collection devices are generally not specifically designed to address this issue. For example, patent CN116058834B discloses an integrated blood sampling and analysis device, but this device does not specifically consider the tissue fluid generated during the needle puncture. Without effective treatment of this tissue fluid, it can lead to errors in blood glucose concentration, affecting the final measurement results. For patients with severe illnesses, errors in blood glucose testing can significantly impact a doctor's judgment and hinder the development of rehabilitation measures. Furthermore, current operating methods often rely on nurses' experience, resulting in cumbersome, inefficient, and error-prone procedures. This is especially problematic in hospital settings with a large number of patients and a shortage of nurses, making it imperative to simplify procedures and increase automation.

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] By designing the collection components, during the blood sampling process after a patient's finger is punctured, the rubber column can squeeze and rub both sides of the fingertip to accelerate the flow of blood from the puncture point and drip out blood containing tissue fluid. With the roll-up mechanism, after the first drop of blood containing tissue fluid drips from the puncture point, the roll-up plate increases the diameter of the roll and lifts the finger, thus facilitating subsequent sampling. The dripped blood can be collected through the collection tube to prevent it from dripping to other places and causing inconvenience for subsequent cleaning.

[0019] Through the above operation, when the patient's other hand is inconvenient to operate, the patient can collect blood samples with one hand. During the blood sampling process, the first drop of blood containing tissue fluid that comes out from the puncture site can be removed, and the subsequent blood flow can be sampled. This can effectively avoid misjudgment caused by tissue fluid in the blood. Moreover, the whole process is automated and does not require manual operation by the patient, which greatly reduces the inconvenience of operation during the blood collection process.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] The present invention will be further described below with reference to the embodiments.

[0034] Example: Refer to Figures 1 to 10 A medical blood sampling device, comprising:

[0035] A base plate 1, with a support frame 101 fixedly installed on its upper end surface;

[0036] The drive assembly 2 includes a rotating wheel 202 disposed above the base plate 1 and on one side of the support frame 101. Multiple collection tubes 207 are slidably mounted in a circumferential array inside the rotating wheel 202. Blood-absorbing paper is fixedly installed on the inner wall of the collection tubes 207. A needle 208 is slidably mounted inside the collection tubes 207. The collection tubes 207 have a blood-stagnation part that is bent inward near the axis of the rotating wheel 202.

[0037] The collection component 3 includes a squeezing block 306, with rubber columns 334 symmetrically arranged above the squeezing block 306. The rubber columns 334 are made of rubber material, which has a certain degree of elasticity to avoid excessive squeezing of the finger during the squeezing process, thus preventing discomfort to the patient. A squeezing head 345 is arranged above the rubber columns 334. A roller 319 is arranged between the squeezing block 306 and the rubber columns 334. A roller plate 322 is fixedly installed on the outer wall of the roller 319. The squeezing block 306 is driven to move, causing the needle 208 to contact and puncture the patient's finger. The rubber columns 334 are driven to move relative to or in opposite directions to knead the patient's finger, squeezing out the first drop of blood. The roller 319 is driven to move and wind around the roller plate 322 to increase the diameter of the roller 319 and lift the patient's finger, facilitating the collection of the second drop of blood.

[0038] A sloping groove 102 is formed on the upper surface of the support frame 101. A first linear drive device 103 is fixedly installed on the upper surface of the base plate 1. A blood glucose meter 104 is fixedly installed on the drive end of the first linear drive device 103. An external frame 105 is fixedly installed on both sides of the drive end of the first linear drive device 103. A connecting plate 106 is fixedly installed on one side of the external frame 105. A rotating disk 107 is rotatably installed on one side of the connecting plate 106. Multiple test strips 108 are slidably installed inside the rotating disk 107. Any one of the test strips 108... All 8 components can be connected to the detection end of the blood glucose meter 104. A stepper motor 109 is fixedly installed on one side of the connecting plate 106. The output end of the stepper motor 109 passes through the connecting plate 106 and is fixedly connected to the rotating disk 107. A protective shell 110 is fixedly installed on the upper surface of the base plate 1. A medical human-computer interaction system is embedded in the upper surface of the protective shell 110. The medical human-computer interaction system includes a display screen and a control module. The blood glucose meter 104 is an existing device used to measure the concentration of glucose (blood sugar) in the blood. To avoid excessively high or low blood sugar levels, the test strip 108 is a key component of the blood glucose meter 104 for measuring blood glucose. It typically contains chemical reagents that react with glucose in the blood, generating electrical signals or chemical reactions. The blood glucose meter 104 measures blood glucose concentration by reading these signals. During blood sampling, the patient needs to clean their fingers with warm water and soap to ensure the blood collection area is clean. A stepper motor 109 drives the rotating disk 107 to rotate in steps, causing the rotating disk 107 to slide each test strip 108 into the detection port of the blood glucose meter 104. During the process of the test strip 108 sliding into the detection port of the blood glucose meter 104, the detection port of the blood glucose meter 104 can be detached from the outside of the blood glucose meter 104. With electrodes connected to the detection port, the rotating test strip 108 can contact the detection port for detection. The test strip 108 slides in contact with the detection port, and after the test strip 108 comes into contact with the patient's blood, it will not affect the output of the detection port electrodes.

[0039] Two fixing brackets 201 are detachably and fixedly installed on the upper end face of the base plate 1, between the support frame 101 and the first linear drive device 103. An inlet is provided on the inner wall of the fixing bracket 201 at a position away from the drum 319. A triangular block is fixedly installed on the inner wall of the inlet. A first fixing bracket 210 and a second fixing bracket 213 are detachably and fixedly installed on the inner bottom end of the fixing bracket 201 and on the upper end face of the base plate 1. A baffle 212 is fixedly installed on the upper end of the first fixing bracket 210. An arc-shaped limiting strip 211 is fixedly installed on the opposite side of the first fixing bracket 210 and the second fixing bracket 213. The outer wall of the arc-shaped limiting strip 211 is rotatably connected to the rotating wheel 202. A vertical plate 203 is fixedly installed on the upper end face of one of the fixing brackets 201. A first rotary drive component 204 is fixedly installed on one side of the vertical plate 203. The first rotary drive component 204 uses an existing rotary motor. The first rotary drive component 204 interacts with a medical device. The system is electrically connected. The output end of the first rotary drive 204 passes through the vertical plate 203 and is fixedly installed with a gear ring. The gear ring meshes with the rotating wheel 202. The outer wall of the rotating wheel 202 has slots 205 arranged in a circumferential array. The outer wall of the rotating wheel 202 has sliding holes between the slots 205. The collection cylinder 207 is slidably connected to the sliding holes. The outer wall of the collection cylinder 207 is fixedly installed with a barrier ring. The first telescopic fixing frame 206 is magnetically installed in the slot 205. The needle 208 is fixedly connected to the first telescopic fixing frame 206 near the axis of the rotating wheel 202. The first telescopic fixing frame 206 and the collection cylinder 207 are fixedly installed with a first spring 209. The needle 208 passes through the collection cylinder 207 and extends into it. The needle 208 and the collection cylinder 207 are slidably connected. The outer wall of the collection cylinder 207 has a retaining ring. The inner wall of the collection cylinder 207 is fixedly installed with a liquid level sensor. The liquid level sensor is electrically connected to the medical artificial interaction system.

[0040] After all the blood samples have been collected from the patient by each needle 208 and collection tube 207, the blood-absorbing paper and blood-retention area can effectively prevent the patient's blood from dripping. At the same time, by disassembling the first fixing bracket 210 and then the fixing frame 201 (the first fixing bracket 210 and the fixing frame 201 are assembled to the upper end face of the base plate 1 by existing screws), the rotating wheel 202 can be removed as a whole, and the needle 208 and collection tube 207 can be replaced as a whole. The medical artificial interaction system can display the test data of the patient in real time, and can also upload the test data to the cloud for recording through the medical artificial interaction system. Furthermore, the needle 208 and collection tube 207 can be customized as disposable parts for customized replacement.

[0041] A liquid level sensor is an existing device that can sense the liquid level and convert the measurement result into an electrical signal. Multiple collection cylinders 207 and multiple needles 208 are positioned by rotating a wheel 202. During each sampling process, the collection cylinders 207 and needles 208 need to be driven between the first fixed bracket 210 and the second fixed bracket 213. The patient's finger needs to be placed above the first fixed bracket 210 and the second fixed bracket 213. During blood sampling, the patient's finger being sampled needs to be taut to avoid being unable to lift the finger later (because there are joints on the finger, if the finger is not taut, it will still contact the baffle 212 after lifting the finger), causing the test strip 108 to not be able to enter the fingertip correctly. After each blood sampling, the first telescopic fixed bracket 206, collection cylinders 207, and needles 208 are removed from the rotating wheel 202 for replacement or cleaning.

In addition, through the setting of the relay, the relay will send voltage to cause the first electromagnet 312 to intermittently generate magnetic force, so as to drive the rubber column 334 to intermittently move relative to each other, thereby intermittently squeezing the fingertip of the patient, accelerating the flow of blood from the puncture point, and causing the blood containing tissue fluid to flow out quickly.

[0047] The working principle of this utility model is as follows:

[0048] 1. Finger puncture: When blood needs to be collected from a patient, the patient's hand is pressed against the support frame 101, and one finger is inserted into the inclined groove 102. The baffle 212 will hold the fingertip, and the fingertip will be positioned above the first fixed bracket 210 and the second fixed bracket 213. The magnetic energized plate 316 is moved by activating the second branch drive device 315 (as shown in the attached diagram). Figure 4 As indicated by the arrow, the magnetic energized plate 316 contacts and presses the block 304. Simultaneously, the energized magnetic plate 316 contacts the conductive block 305, magnetically attracting it and supplying voltage to the conductive block 305. The pressed block 304 drives the straight rod 302 to slide towards the inner wall of the inner cavity 307. During the sliding process of the block 304 towards the inner wall of the inner cavity 307, it contacts the stop bar 308, causing the pressing block 306 to move towards the first fixed bracket 210. At the same time, it causes the vertical block 309 to move together, stretching the third spring 310. The pressed block 306, driven to move, contacts the lower part of the first telescopic fixed frame 206, causing the first telescopic fixed frame 206 to slide. The first spring 209 is stretched as the needle 208 slides inside the collection cylinder 207, moving towards the fingertip. As the first telescopic fixing frame 206 is continuously driven to move, the needle 208 is continuously driven to move towards the fingertip and pierce it. At this time, the straight rod 302 will completely break through the obstruction of the stop bar 308 due to the squeezing force and slide towards the inner wall of the inner cavity 307. The stretched third spring 310 will drive the squeezing block 306 to move towards the stop block 301 and disengage from the lower end of the first telescopic fixing frame 206. The stretched first spring 209 will drive the collection cylinder 207 to retract into the needle 208. During this process, the fingertip is completely pierced and bleeding occurs.

[0049] 2. Finger Rubbing: During the movement of block 304, block 304 will drive L-shaped rod 311 and first electromagnet 312 to move between second magnet 338. After magnetic energizing plate 316 contacts conductive block 305 and supplies power to conductive block 305, voltage will be supplied to pulse signal generator, relay, and first electromagnet 312 through conductive block 305. During this process, the pulse signal generator will control the relay to intermittently supply voltage to first electromagnet 312, causing first electromagnet 312 to be intermittently energized, generating magnetic force and attracting second magnet 338 to approach first electromagnet 312. As second magnet 338 approaches first electromagnet 312, it will drive relative movement of lower connecting frame 337, F-shaped frame 333, and rubber column 334 (as shown in the attached diagram). Figure 8 As shown by the middle arrow, when the rubber column 334 moves relative to the finger, the rubber column 334 will rotate through the meshing of the toothed groove at the lower end of the upper linkage plate 336 with the toothed disc 335. The rotating rubber column 334 will continuously squeeze and rub the finger on both sides. When the fingertip has been pierced, the squeezing and rotating rubbing of the rubber column 334 relative to the finger on both sides can accelerate the bleeding at the piercing point, causing the blood containing tissue fluid to drip down and into the collection cylinder 207. The liquid level sensor will detect the blood dripping into the collection cylinder 207.

[0050] 3. Blood Sampling: During the movement of the L-shaped rod 311, the outer block 313 and the first conductive contact 314 move, allowing the first conductive contact 314 to contact and energize the second conductive contact 329. The energized second conductive contact 329 supplies voltage to the first magnet 326, causing the first magnet 326 to generate magnetic force. The magnetic force generated by the first magnet 326 attracts the second electromagnet 327, causing the long plate 325 and the round rod 323 to move towards the inner wall of the U-shaped slide rail 317. During the movement of the long plate 325... The fourth spring 324 is compressed in the middle, and the round rod 323 moves during the process, which drives the slider 320 and the drum 319 to move towards the clamping plate 330. During the process of being driven to move, the drum 319 drives the tooth head 321 to move together. The tooth head 321 will mesh with the tooth plate 318 to drive the drum 319 to rotate. The rotating drum 319 will wind the rolling plate 322 around its outer wall, thereby increasing the diameter of the drum 319. The increased diameter of the drum 319 will lift the finger for blood sampling, so that the height of the fingertip is higher than the baffle 212.

[0051] While the first magnet 326 generates magnetic force to attract the second electromagnet 327 to move, the first linear drive device 103 is also driven to move, causing the blood glucose meter 104 and the test strip 108 to move above the first fixed bracket 210 and the second fixed bracket 213, and move to the lower part of the fingertip through the inlet and the triangular block to contact the blood at the puncture point. The triangular block can raise the test strip 108 at a certain angle to avoid the test strip 108 contacting the baffle 212 and causing movement obstruction. The test strip 108 will perform the test after contacting the blood.

[0052] After the test is completed, the magnetic energized plate 316 is reset by the second branch drive device 315 and stops contacting and energizing the square block 304 and the conductive block 305. The second spring 303 will drive the straight rod 302 to reset. The fifth spring 340 will drive the F-shaped frame 333, the lower connecting frame 337, and the second magnet 338 to reset. The fourth spring 324 will drive the long plate 325 and the round rod 323 to reset, so as to facilitate the next test.

[0053] It should be noted that after the first conductive contact 314 and the second conductive contact 329 make contact and are energized, during the process of the second conductive contact 329 transmitting voltage to the first magnet 326, the voltage transmission to the first magnet 326 is delayed by a delay switch, so that the finger can be lifted to take a sample after the first drop of blood containing tissue fluid drips from the fingertip.

[0054] It should also be noted that when blood is punctured and dripped into the collection cylinder 207 and detected by the liquid level sensor, an electrical signal is generated. The medical artificial interaction system controls the voltage supplied to the first rotating drive 204, causing the first rotating drive 204 to drive the rotating wheel 202 to rotate. Each rotation is a set angle, driving the new needle 208 to move between the first fixed bracket 210 and the second fixed bracket 213 for the next detection. During the rotation of the rotating wheel 202, the rotation time can be delayed by the medical artificial interaction system, and the rotation can start after the previous blood sampling is completed to avoid interfering with the previous blood sampling.

[0055] It should be noted that after each complete replacement of the test strip 108, during the first blood sampling process after the replacement of the test strip 108, the medical human-computer interaction system will provide a reminder. After the entire setup is completed after replacing the test strip 108, the medical human-computer interaction system will issue an alarm to remind the patient to replace the test strip. Before the blood sampling and testing of the current patient is completed using the test strip 108, collection tube 207, and lancet 208, the blood sampling cycle for each patient can be set. The operation time for the above steps can be preset according to the actual situation (e.g., pricking the finger: 2 seconds, squeezing the finger: 4 seconds, lifting the finger: 3 seconds). After the set blood sampling cycle is completed, the system will rotate to use the new test strip 108, collection tube 207, and lancet 208 for the patient to have their blood sampled. Before each blood sampling, the human-computer interaction system will remind the patient to place their finger. The above is a mature existing technology and therefore will not be elaborated further.
