[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A puncture specimen tube, comprising a glass tube and a stabilizing component;

[0007] The outer periphery of the glass tube is slidably connected to a stabilizing component, and the stabilizing component is used to maintain the vertical placement state of the glass tube to prevent the glass tube from tilting;

[0008] The stabilizing assembly comprises a sliding block, a displacement groove, an adjusting groove, a displacement rod, a toggle block and a supporting leg. The outer periphery of the glass tube is slidably connected to a tubular sliding block. A plurality of displacement grooves are arranged in an annular array on the top wall of the sliding block. The plurality of displacement grooves all penetrate the sliding block. The sides of the plurality of displacement grooves away from the glass tube are connected to an adjusting groove. The plurality of adjusting grooves all penetrate the side wall of the sliding block. A displacement rod is slidably connected in the plurality of displacement grooves. The side walls of the plurality of displacement rods close to the adjusting groove are fixedly connected to the toggle block. The toggle block is slidably connected to the adjusting groove. The bottom walls of the plurality of displacement rods are tilted and fixedly connected to the supporting leg.

[0009] Preferably, the surface of the sliding block close to the glass tube is fixedly connected to the rubber layer.

[0010] Preferably, both the sliding block and the displacement rod are made of magnetic materials, and the sliding block and the displacement rod are magnetically attracted to each other, so as to fix the height of the displacement rod in the adjustment groove.

[0011] Preferably, a sealing assembly is provided on the outer periphery of the glass tube, and the sealing assembly is located above the stabilizing assembly;

[0012] Preferably, the sealing assembly includes a fixing ring, an elastic cord, and a plug. A ring-shaped fixing ring is fixedly connected to the outer periphery of the glass tube. One end of the elastic cord is fixedly connected to the outer periphery of the fixing ring, and the other end of the elastic cord is fixedly connected to the plug. The plug is movably connected to the open end of the glass tube.

[0013] Preferably, the stabilizing assembly further includes a suction disc and a bladder. The bottom ends of several support legs are fixedly connected to the suction disc. The suction disc is in the shape of an inverted disc, and a circular hole is formed at the center position of the suction disc. The outer peripheries of several displacement rods are wrapped with bladders, and the circular holes of the suction discs on several displacement rods communicate with the bladders.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. When it is necessary to puncture and extract cerebrospinal fluid from a patient, first separate the plug from the glass tube, then connect the glass tube to the end of the needle. Then, the doctor inserts the needle into the patient's body, and the cerebrospinal fluid is drawn into the glass tube by the needle. After the extraction is completed, separate the glass tube from the needle, and seal the cerebrospinal fluid in the glass tube with the plug, avoiding the overflow or contamination of the cerebrospinal fluid from the glass tube, ensuring the purity of the cerebrospinal fluid in the specimen tube. Then, by pushing several toggle lever blocks to slide down in the adjustment groove, several displacement rods move down in the displacement groove, and several support legs contact the table, so that the glass tube is vertically fixed, improving the stability of the puncture specimen tube.

[0016] 2. By fixing an inverted disc-shaped suction disk at the bottom of several supporting legs, and opening a circular hole at the center of each suction disk, when the physician drives the displacement rod and the supporting legs to contact the desktop by pressing down the toggle block, the suction disk will be compressed and deformed to fit the desktop. At the same time, the air between the suction disk and the desktop will enter the capsule through the circular hole. The air-intake capsule will increase the friction between the displacement rod and the displacement groove, further locking the position of the displacement rod, thereby effectively preventing the glass tube from shifting up and down or shaking when subjected to external force. Since the air between the suction disk and the desktop is continuously discharged from the circular hole, a relatively closed space is formed between the suction disk and the desktop. As the process of outside air entering the capsule through the circular hole ends, the air pressure in the closed space gradually decreases, generating a negative pressure effect. This negative pressure makes the suction disk more firmly adsorbed on the desktop, thereby enhancing the overall stability of the puncture specimen tube, further improving the anti-overturning ability of the puncture specimen tube when hit by external force, and effectively ensuring the safety of the specimen and the accuracy of detection.

Example 1

[0026] As attached Figure 1 To Attachment Figure 3 As shown:

[0027] The utility model provides a puncture specimen tube, comprising a glass tube 100 and a stabilizing component 300;

[0028] The outer periphery of the glass tube 100 is slidably connected to a stabilizing assembly 300, and the stabilizing assembly 300 is used to maintain the vertical placement state of the glass tube 100 to prevent the glass tube 100 from tilting;

[0029] The stabilizing assembly 300 includes a sliding block 310, a displacement groove 320, an adjustment groove 330, a displacement rod 340, a toggle block 350, and a support leg 360. The outer periphery of the glass tube 100 is slidably connected to the annular sliding block 310. A plurality of displacement grooves 320 are arranged in an annular array on the top wall of the sliding block 310. The plurality of displacement grooves 320 are all connected to an adjustment groove 330 on the side away from the glass tube 100. The plurality of adjustment grooves 330 are all penetrated through the side wall of the sliding block 310. A displacement rod 340 is slidably connected in the plurality of displacement grooves 320. The side walls of the plurality of displacement rods 340 close to the adjustment groove 330 are fixedly connected to the toggle block 350. The toggle block 350 is slidably connected to the adjustment groove 330. The bottom walls of the plurality of displacement rods 340 are all tilted and fixedly connected to the support leg 360.

[0030] Specifically, the surface of the sliding block 310 close to the glass tube 100 is fixedly connected to the rubber layer.

[0031] Specifically, both the sliding block 310 and the displacement rod 340 are made of magnetic materials, and the sliding block 310 and the displacement rod 340 are magnetically attracted to each other, so as to fix the height of the displacement rod 340 in the adjustment groove 330.

[0032] Specifically, a sealing assembly 200 is arranged on the outer periphery of the glass tube 100, and the sealing assembly 200 is located above the stabilizing assembly 300;

[0033] The sealing assembly 200 includes a fixing ring 210, an elastic cord 220, and a plug 230. A ring-shaped fixing ring 210 is fixedly connected to the outer periphery of the glass tube 100. One end of the elastic cord 220 is fixedly connected to the outer periphery of the fixing ring 210, and the other end of the elastic cord 220 is fixedly connected to the plug 230. The plug 230 is movably connected to the open end of the glass tube 100.

[0034] In a specific implementation, when it is necessary to puncture a patient to extract cerebrospinal fluid, first separate the plug 230 from the glass tube 100, then connect the glass tube 100 to the end of the needle. Then, the doctor inserts the needle into the patient's body, and the cerebrospinal fluid is drawn into the glass tube 100 by the needle. After the extraction is completed, separate the glass tube 100 from the needle, and seal the cerebrospinal fluid in the glass tube 100 through the plug 230, avoiding the overflow or contamination of the cerebrospinal fluid from the glass tube 100, ensuring the purity of the cerebrospinal fluid in the specimen tube. Then, by pushing several dialing blocks 350 to slide down in the adjustment groove 330, several displacement rods 340 move down in the displacement groove 320, and several support legs 360 contact the table, so that the glass tube 100 is vertically fixed, improving the stability of the puncture specimen tube. Embodiment 2

[0035] When the puncture specimen tube standing on the table is impacted by an external force, the glass tube 100 will still be tilted, and then there is a risk of the glass tube 100 breaking and the cerebrospinal fluid flowing out. Therefore, Embodiment 2 further improves Embodiment 1.

[0036] As shown in the attached Figure 4 figure, the stabilizing assembly 300 further includes a suction disc 370 and a bladder 380. The bottom ends of several support legs 360 are fixedly connected to the suction disc 370. The suction disc 370 is in the shape of an inverted disc, and a round hole is opened at the center position of the suction disc 370. The outer peripheries of several displacement rods 340 are all wrapped with the bladder 380, and the round holes of the suction disc 370 on several displacement rods 340 communicate with the bladder 380.

[0037] By fixing the inverted disc-shaped suction disc 370 at the bottom of the plurality of support legs 360, and opening a circular hole at the center of each suction disc 370, when the doctor drives the displacement rod 340 and the support leg 360 to contact the desktop by pressing down the toggle block 350, the suction disc 370 will be deformed under pressure and fit the desktop, and at the same time, the air between the suction disc 370 and the desktop will enter the capsule 380 through the circular hole. The air-intake capsule 380 will increase the friction between the displacement rod 340 and the displacement groove 320, further locking the position of the displacement rod 340, thereby effectively preventing the glass tube 100 from being deformed under pressure. When external force acts, up and down displacement or shaking occurs. Since the air between the suction disk 370 and the desktop is continuously discharged from the circular hole, a relatively closed space is formed between the suction disk 370 and the desktop. As the process of the outside air entering the capsule 380 through the circular hole ends, the air pressure in the closed space gradually decreases, resulting in a negative pressure effect. This negative pressure makes the suction disk 370 more firmly adsorbed on the desktop, thereby enhancing the overall stability of the puncture specimen tube, further improving the anti-overturning ability of the puncture specimen tube when hit by external force, and effectively ensuring the safety of the specimen and the accuracy of the detection.

[0038] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
