[0002] A blood collection tube is a disposable, negative-pressure vacuum glass tube that can achieve quantitative blood collection and needs to be used with a venous blood collection needle.

[0003] At present, when blood is collected from chronic patients, the elderly and other people in areas with relatively scarce medical care, vacuum blood collection tubes are usually used to better preserve the blood samples. After the blood is collected, the vacuum blood collection tubes are generally placed in special storage boxes for easy transportation, and then the blood samples are sent to the hospital laboratory in surrounding cities with more developed medical care for testing;

[0004] However, the existing storage boxes usually have multiple placement slots inside the box, and then the blood collection tubes are directly placed in the placement slots without any preventive measures. As a result, when bumps occur during transportation, the blood collection tubes are easily caused to collide or collide with the inner wall of the box and break, causing the blood inside the blood collection tube to flow out and affect the blood quality. In view of this, the present invention is specially proposed. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0032] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A medical blood collection tube storage device comprises a base 1 and a support plate 101 connected to the base 1, wherein the support plate 101 is provided with a plurality of groups of plug holes 102, a water bag 104 for wrapping the blood collection tube is arranged around the plug hole 102, and a liquid storage chamber 206 is provided in the base 1; a water pump 2 is fixedly installed in the liquid storage chamber 206 and is used to suck the frozen water stored in the liquid storage chamber 206 into the water bag 104; a buffer cylinder 4 is fixedly installed on the base 1; a piston disc 401 is slidably connected in the buffer cylinder 4; a support rod 403, one end of which is fixedly connected to the piston disc 401, and the other end is fixedly connected to the support plate 101; a spring 402 is arranged in the buffer cylinder 4, wherein one end of the spring 402 is fixedly connected to the inner wall of the buffer cylinder 4, and the other end is fixedly connected to the piston disc 401, and the buffer cylinder 4 is fixedly connected with an air inlet pipe 404 and an air outlet pipe 405.

[0033] A support plate 2 5 is fixedly connected to the support plate 1 101, a support groove 501 is provided on the support plate 2 5, a through hole penetrating the support plate 2 5 is provided at the lower end of the support groove 501, the through hole is used in conjunction with the plug hole 102, an air bag 503 is arranged around the support groove 501, an air delivery cavity 506 is provided in the support plate 2 5, the air delivery cavity 506 is connected to the air bag 503 through an air delivery pipe 507, and the end of the air outlet pipe 405 away from the buffer cylinder 4 is connected to the air delivery cavity 506.

[0034] A limiting groove connected to the plug hole 102 is provided on the support plate 101, and a support ring 203 is slidably connected in the limiting groove. An annular groove is provided on the support ring 203. An infusion cavity 201 is provided in the support plate 101. The infusion cavity 201 is connected to the annular groove through an infusion tube 202, and the annular groove is connected to the water bag 104 through a connecting tube 204. The output end of the water pump 2 is connected to the infusion cavity 201 through a hose.

[0035] The air release pipe 504 is fixedly connected to a pressure relief pipe 505 , and the pressure relief pipe 505 is provided with a pressure relief valve.

[0036] When placing the blood collection tube, first insert the blood collection tube into the insertion hole 102 through the support groove 501 and the through hole, so that the tube body of the blood collection tube is located in the insertion hole 102 and the tube cover is located in the support groove 501. Since the diameter of the tube cover is larger than the diameter of the blood collection tube, the tube cover located in the support groove 501 can provide support for the tube body;

[0037] After the placement is completed, the water pump 2 is started, so that the water pump 2 draws the chilled water stored in the liquid storage chamber 206 and transports it into the infusion chamber 201 through the hose, and then the chilled water is transported into the annular groove through the infusion tube 202, and finally transported into the water bag 104 through the connecting tube 204, so that the water bag 104 expands until it wraps around the tube body, so as to achieve the clamping and fixation of the blood collection tube. A one-way valve is provided on the infusion tube 202, and then the water pump 2 is closed. At the same time, the chilled water transported into the water bag 104 can achieve the effect of cold storage of the blood in the blood collection tube, and the water bag 104 is arranged in a cylindrical shape to maximize the contact area between the water bag 104 and the tube body, which can not only improve the stability of the clamping and fixation of the blood collection tube, but also improve the effect of cold storage of the blood in the blood collection tube.

[0038] The storage device facilitates the transportation of the blood collection tubes. In the process of transportation, when the support plate 101 and the support plate 2 5 reciprocate vertically on the base 1 through the spring 1 402, the spring 1 402 can provide buffering and shock absorption for the support plate 101, thereby preventing the blood collection tubes from falling off from the water bag 104 and causing damage due to the bumps.

[0039] When the support plate 101 bumps up and down, the support rod 403 drives the piston disc 401 to move up and down in the buffer cylinder 4, thereby forming a piston movement. When the piston disc 401 moves downward to compress the spring 402, external gas can be sucked into the buffer cylinder 4 through the air inlet pipe 404. When the compressed spring 402 pushes the piston disc 401 to move upward, the piston disc 401 can transport the gas in the buffer cylinder 4 into the air delivery cavity 506 through the air outlet pipe 405. Then the gas can be transported into the air bag 503 through the air delivery pipe 507, causing the air bag 503 to expand and wrap the tube cover, so as to achieve the clamping and fixation of the blood collection tube, and further improve the stability of the clamping and fixation of the blood collection tube. One-way valves are arranged on the air inlet pipe 404, the air outlet pipe 405 and the air delivery pipe 507.

[0040] It should be noted that when the air pressure in the pressurized airbag 503 is greater than the pressure relief value set by the pressure relief valve on the pressure relief pipe 505, the pressure relief valve automatically opens to relieve pressure, so that the high-pressure gas in the airbag 503 is discharged from the airbag 503 through the pressure relief pipe 505, thereby keeping the pressure inside the airbag 503 constant.

[0041] It should be noted that the air outlet pipe 405 is a stretchable and shrinkable hose, so the air outlet pipe 405 will not interfere with the up and down reciprocating motion of the support plate 1 101 and the support plate 2 5 .

[0042] Example 2: Reference Figure 2 , Figure 5 , Figure 6, a medical blood collection tube storage device, which is basically the same as Example 1, and further, a fixing sleeve 2 502 is provided in the support groove 501, and the air bag 503 is arranged around the fixing sleeve 2 502, and a guide groove 6 is opened on the inner wall of the support groove 501, and a slider 601 is fixedly connected to the fixing sleeve 2 502, and the slider 601 is slidably connected to the guide groove 6; it also includes a fixing sleeve 103 rotatably connected to the plug hole 102, and the water bag 104 is arranged around the fixing sleeve 103.

[0043] A groove connected to the plug-in hole 102 is provided on the support plate 101, and a fixing ring 3 fixedly connected to the fixing sleeve 103 is provided in the groove. A torsion spring 301 is provided in the groove, and one end of the torsion spring 301 is fixedly connected to the fixing ring 3, and the other end is fixedly connected to the inner wall of the groove. A locking hole is provided on the fixing ring 3, and a threaded hole connected to the groove is provided at the lower end of the support plate 101, and a bolt 302 is threadedly connected in the threaded hole, and the bolt 302 is inserted into the locking hole. A plurality of paddles 303 are fixedly connected to the upper end of the fixing sleeve 103 at equal intervals.

[0044] The device further comprises a liquid discharge tube 205 , one end of which is fixedly connected to the liquid infusion tube 202 , and the other end of which is fixedly connected to the liquid storage chamber 206 . A solenoid valve is disposed on the liquid discharge tube 205 .

[0045] When it is necessary to remove the blood collection tube from the storage device so that the blood stored in the blood collection tube can be tested, the bolt 302 is first rotated to make the bolt 302 rotate outward of the locking hole until the bolt 302 moves out of the locking hole and retracts into the threaded hole, thereby releasing the limit fixation of the fixing ring 3. At this time, the torsion spring 301 that has been twisted and accumulated force is released, thereby driving the fixing ring 3 to drive the fixing sleeve 103 to rotate, and the fixing sleeve 103 drives the tube body to rotate synchronously, so that the blood in the tube body is shaken to ensure that the blood and the additive in the tube body are fully mixed. Therefore, during the test, there is no need to shake the blood in the tube body, and the blood can be tested, thereby improving the work efficiency of blood testing;

[0046] At the same time, when the fixing sleeve 103 drives the tube body to rotate, it can also drive the fixing sleeve 2 502 to move upward in the support groove 501 (it should be noted that the slider 601 that follows the fixing sleeve 2 502 to slide upward in the guide groove 6 can play a limiting and guiding role for the fixing sleeve 2 502, so that the fixing sleeve 2 502 can only move upward in the support groove 501). At the same time, the fixing sleeve 2 502 drives the tube cover to move upward synchronously, thereby separating the tube cover from the tube body, so that the tube cover is automatically removed from the tank body. , and then open the solenoid valve on the drainage pipe 205, so that the liquid is discharged from the water bag 104 through the connecting pipe 204, the annular groove, the infusion tube 202, and the drainage pipe 205 in turn, thereby releasing the limit fixation of the tube body, and then take out the tube body located in the plug hole 102 from under the support plate 101, so that the blood in the tube body can be directly tested, further improving the working efficiency during blood testing, and then the chilled water discharged from the water bag 104 flows back into the liquid storage chamber 206 for recycling, thereby reducing the waste of water resources.

[0047] It should be supplemented that, since the drain pipe 205 adopts a stretchable and shrinkable hose, the drain pipe 205 will not interfere with the up and down reciprocating motion of the support plate 1 101 and the support plate 2 5 .

[0048] It should be noted that, by providing a plurality of paddles 303 , it is convenient for the user to drive the fixing sleeve 103 to drive the fixing ring 3 to rotate, thereby storing force on the torsion spring 301 .

[0049] Example 3: Reference Figure 7 , Figure 8 , Fig. 9 , a medical blood collection tube storage device, which is basically the same as embodiment 1, and further, a protective cover 7 is detachably connected to the base 1.

[0050] A fixing block 702 is fixedly connected to the base 1, a connecting hole 701 used in conjunction with the fixing block 702 is provided on the protective cover 7, sliding grooves 703 are provided at both ends of the fixing block 702, a snap-in block 704 is slidably connected in the sliding groove 703, a spring 705 is provided in the sliding groove 703, one end of the spring 705 is fixedly connected to the snap-in block 704, and the other end is fixedly connected to the inner wall of the sliding groove 703.

[0051] After the blood collection tubes are stored, the protective cover 7 is covered on the base 1 to cover the blood collection tubes stored in the storage device, thereby improving the protection effect of the blood collection tubes and preventing the blood collection tubes from being damaged by external objects during transportation;

[0052] When the locking cam 710 is in the closed position, the locking cam 710 will be in the closed position, and the locking cam 710 will be in the closed position when the locking cam 710 is in the closed position.

[0053] Example 4: Reference Figure 6 , a medical blood collection tube storage device, which is basically the same as that of embodiment 1, and further, the airbag 503 is fixedly connected to a deflation tube 504, and the deflation tube 504 is provided with a solenoid valve;

[0054] When the removed tube cover needs to be taken out from the support groove 501 , the solenoid valve on the vent pipe 504 is opened to allow gas to be taken out of the airbag 503 through the vent pipe 504 , thereby releasing the limit fixation on the tube cover, and then the tube cover can be taken out from the support groove 501 .

[0055] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as above with a preferred embodiment, it is not used to limit the present invention.
