Description

Technical Field

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

[0002] Liquid-liquid extraction, also known as solvent extraction or extraction, is the process of separating and extracting components from a liquid mixture using a solvent. A selected solvent that is immiscible (or slightly miscible) with the liquid mixture is added, and the different solubilities of the components in the solvent are used to achieve separation or extraction. Examples include using benzene as a solvent to separate phenol from coal tar, and using isopropyl ether as a solvent to recover acetic acid from a dilute acetic acid solution. In the laboratory, it is performed using instruments such as separatory funnels, while in industry, it is carried out in packed towers, sieve tray towers, centrifugal extractors, spray extractors, etc., and is applied in organic chemistry, petroleum, food, pharmaceutical, rare element, and nuclear energy industries.

[0003] Existing patent CN214019325U discloses an adjustable support for plasma extraction. This utility model includes a support plate and a placement plate for placing an extraction vessel. The placement plate and support plate are rotatably connected by a rotating shaft. The end of the rotating shaft away from the placement plate passes through the support plate and has a handle. A support plate parallel to the bottom of the placement plate is provided for placing a collection tube. Multiple positioning holes for positioning the extraction vessel are evenly distributed on the placement plate. An adjustment mechanism for adjusting the height of the support plate is provided inside the support plate. The adjustment mechanism includes a lead screw rotatably disposed inside the support plate. A driven gear is provided at the bottom end of the lead screw, and a driving gear meshing with the driven gear is provided on one side of the driven gear. A transmission shaft is provided at the end of the driving gear away from the driven gear. By providing an adjustment mechanism, the problem of inconvenience in adjusting the position of the collection tube according to actual conditions in existing devices can be solved, making it highly practical.

[0004] However, although the existing patent CN214019325U has an adjustment mechanism that can solve the problem of inconvenience in adjusting the position of the liquid collection tube according to the actual situation in the existing device and is highly practical, if the blood sample is not subjected to anticoagulation treatment while waiting for extraction, it may coagulate, which will affect the extraction. During the extraction or movement of the blood sample, it may vibrate, which may lead to blood sample leakage. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a novel blood sample extraction device to solve the problems mentioned in the background art, such as the possibility of coagulation of blood samples during the extraction process if anticoagulation treatment is not performed, which would affect the extraction; and the possibility of blood sample leakage during extraction or movement due to vibration.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a novel blood sample extraction device, comprising a base, a support frame fixedly mounted on the top of the base, one side of the support frame being fixedly connected to a first sleeve, a second sleeve being disposed inside the first sleeve, a sealing cap being fixedly mounted on the top of the second sleeve, an anticoagulation mechanism being disposed inside the second sleeve, and a shock-absorbing mechanism being disposed in the middle of the first sleeve and the second sleeve.

[0009] Preferably, the anticoagulation mechanism includes a geared motor, a connecting frame, and a sampling tube limiting groove. The geared motor is provided at the bottom of the inner side of the second sleeve, and the inner side of the sampling tube limiting groove is used to place the blood sample sampling tube.

[0010] Preferably, the transmission end at the top of the geared motor is fixedly connected to the connecting frame, and the outer side of the connecting frame is fixedly connected to the sampling tube limiting groove. The sealing cover serves to prevent dust. When the geared motor is started, it drives the connecting frame and the sampling tube limiting groove to rotate around the center of the second sleeve, which serves to prevent coagulation.

[0011] Preferably, the shock absorption mechanism includes a telescopic shaft, a buffer spring, and a damping shock absorber. The telescopic shafts are evenly distributed on the inner side of the first sleeve. When the device collides during movement or extraction, causing the second sleeve to shake, the telescopic shaft is compressed by the second sleeve and contracts, which in turn causes the buffer spring to contract.

[0012] Preferably, a buffer spring is provided on the outer side of the telescopic shaft, the side of the telescopic shaft away from the first sleeve is connected to the damping shock absorber, and the side of the damping shock absorber away from the telescopic shaft is connected to the second sleeve. The damping shock absorber can absorb the potential energy generated by the spring's reset, thereby playing a role in shock absorption.

[0013] Preferably, an anti-slip pad is fixedly provided at the bottom of the base, a lampshade is provided on one side of the support frame, and an LED tube is provided on the inner side of the support frame near the lampshade. The battery can power the LED tube, and the anti-slip pad serves to prevent slipping.

[0014] Preferably, a battery is installed on the inner side of the support frame, and the battery is electrically connected to the LED lamp. A switch is installed on one side of the support frame, and the switch signal is connected to the LED lamp. The liquid-liquid extraction tube is fixedly installed on the top of the sealing cover. The test cell is fixedly installed on the inner side of the base. The drug component chromatographic comparison card is fixedly installed on the top of the base. When the user performs extraction, the switch can be turned on, and the LED lamp will light up for illumination. The drug component chromatographic comparison card is used to detect the concentration of the drug in the plasma.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this novel blood sample extraction device, the inner side of the sampling tube limiting groove is used to place the blood sample sampling tube. The sealing cap is set to prevent dust. When the geared motor is started, it drives the connecting frame and the sampling tube limiting groove to rotate around the center of the second sleeve, which plays an anticoagulant role.

[0017] 2. In this novel blood sample extraction device, when the device is moved or during extraction and a collision causes the second sleeve to shake, the telescopic shaft contracts under the pressure of the second sleeve, which in turn causes the buffer spring to contract. The damping shock absorber can absorb the potential energy generated by the spring's reset, thus reducing vibration. When the user is extracting, they can turn on the switch, and the battery can power the LED light tube, which then lights up for illumination. The anti-slip pad provides anti-slip protection, and the drug component chromatographic comparison card is used to detect the concentration of drugs in the plasma. Attached Figure Description
