Description

Technical Field

[0001] The utility model belongs to the technical field of blood separation, and particularly relates to a supernatant transfer device obtained by separating blood. Background Art

[0002] Human blood is composed of blood cells and cell-free plasma. In medical and scientific research, it is usually necessary to separate the two (i.e., blood separation) for subsequent specimen measurement. At present, there are at least two schemes for blood separation. The first is to collect the blood sample into a non-anticoagulant blood collection tube. The blood will coagulate after leaving the body, and platelets will wrap the blood cells to form a thrombus and precipitate to the bottom. The supernatant at this time is platelet-free serum. The second is to collect the blood sample into a blood collection tube containing an anticoagulant, and use a centrifuge to centrifuge at a slightly lower speed. The cells with higher density will sink to the bottom, and the supernatant at this time is plasma. After that, the supernatant is extracted and preserved using equipment to achieve blood separation.

[0003] In medical practice, blood and other patient fluids are usually considered potential contaminants because they may carry pathogens. Improper operation may cause cross infection between patients and medical staff. Therefore, medical institutions usually set relevant operating specifications and equip corresponding protective equipment. The disposal of blood after collection must also be strictly carried out in accordance with the procedures for medical waste treatment. The aforementioned blood separation process is actually the treatment of potential contaminants, which must be carried out in accordance with relevant procedures to avoid occupational exposure of medical staff.

[0004] Pipettes, droppers and syringes are commonly used liquid transfer devices, which are used to absorb and move liquids. They are simple and convenient to operate. At present, medical staff usually use the above-mentioned liquid transfer devices to transfer the supernatant separated from blood from blood collection tubes to storage tubes such as freezing tubes for storage. This is a method of artificially separating the supernatant. Of course, integrated experimental equipment can also be used to extract and store the supernatant separated from blood, which is a method of intelligently separating the supernatant.

[0041] Embodiment 1:

[0042] like Figure 1-Figure 6 As shown, the supernatant transfer device provided by this embodiment comprises a transparent plastic box 1, a rubber glove 6, a first storage part, a blood collection tube 9, a second storage part, a storage tube 12 and a liquid converter, wherein:

[0043] The top of the transparent plastic box 1 is penetrated to form a box opening, and a box cover 2 for sealing the box opening is connected to the transparent plastic box 1. The box cover 2 can be buckled on the top of the transparent plastic box 1 by a snap connection. When the box cover 2 is opened, medical staff can easily take and put various components in the transparent plastic box 1. When the box cover 2 is closed, a closed space is formed inside the transparent plastic box 1. A handle 5 is also installed on the box cover 2 to facilitate medical staff to carry and transport the supernatant transfer device.

[0044] Two openings 3 are provided on the side wall of the transparent plastic box 1, and a rubber glove 6 is bonded to each opening 3, and the opening 3 is blocked by the rubber glove 6. The rubber glove 6 is located inside the transparent plastic box 1, and the medical staff can respectively pass their hands through the two openings 3 and respectively extend their hands into the two rubber gloves 6, so that the medical staff can operate in the transparent plastic box 1 with their hands. Optionally, a sliding door 4 is slidably installed on the outer side wall of the transparent plastic box 1, and the sliding door 4 blocks the opening 3 from the outside. That is, the number of the sliding doors 4 is two, and the two sliding doors 4 block the two openings 3 respectively. In this way, when the supernatant does not need to be transferred, the sliding door 4 is used to block the opening 3 to prevent external pollutants from entering the rubber gloves 6.

[0045] The first storage part is detachably installed in the transparent plastic box 1, and the blood collection tube 9 is installed in the first storage part.

Moreover, with the help of this device, medical staff can carry out the above transfer of the supernatant at any place without being restricted by the site. During the transfer, medical staff only need to perform simple operations to complete it. In addition, the supernatant transfer device of this structure also has the advantage of low cost.

[0048] As another implementation of this embodiment, the opening 3 in this embodiment can also be set on the box cover 2.

[0049] Optionally, the first storage portion is a first box body 7, which is detachably fixedly connected to the bottom of the transparent plastic box 1 by snapping, and the first box body 7 is located at the left rear of the transparent plastic box 1. A first opening is formed through the top of the first box body 7, and a first block 8 is provided inside the first box body 7. A first plug hole is provided on the top surface of the first block 8, and the blood collection tube 9 is inserted into the first plug hole and is located in the first box body 7. The number of first plug holes can be several, so that it is convenient to insert multiple blood collection tubes 9 in the first storage portion. In addition, after the blood collection tube 9 is inserted into the first plug hole, it is located inside the first box body 7. The blood collection tube 9 is installed in the first box body 7 by plugging, so as to facilitate taking and placing.

[0050] Optionally, the second storage part is a second box body 10, which is detachably fixedly connected to the bottom of the transparent plastic box 1 by snapping, and the second box body 10 is located in the left front of the transparent plastic box 1. The top of the second box body 10 is penetrated to form a second opening, and a second block 11 is arranged inside the second box body 10. The top surface of the second block 11 is provided with a second plug hole, and the storage tube 12 is inserted into the second plug hole and is located in the second box body 10. The number of second plug holes can be several, so that it is convenient to insert multiple storage tubes in the second storage part. Optionally, the storage tube in this embodiment can be a cryotube. When the storage tube is inserted into the second plug hole, it is located inside the second box body 10. The blood collection tube 9 is installed in the second box body 10 by plugging, so as to facilitate taking and placing.

[0051] Optionally, the liquid transfer device in the present embodiment is a pipette 13. Of course, the liquid transfer device can also be a syringe and a dropper. The present embodiment is described by taking the liquid converter as a pipette 13 as an example. The pipette 13 is equipped with a plurality of gun tips 20. It should be noted that the pipette 13 is a prior art, so it is not described in detail again. A fixed bracket 14 is provided on the inner wall of the rear side of the above-mentioned transparent plastic box 1, and the above-mentioned pipette 13 is detachably fixedly installed on the above-mentioned fixed bracket 14. When it is necessary to transfer the supernatant, the pipette 13 is removed from the fixed bracket 14. When it is not necessary to transfer the supernatant, the pipette 13 is installed on the fixed bracket 14. Specifically, the above-mentioned fixing bracket 14 can be two elastic buckles 141 distributed one above and one below on the inner wall of the rear side of the transparent plastic box 1. The front end of the elastic buckle 141 is provided with an elastic bayonet. The pipette gun 13 is inserted into the above-mentioned elastic buckle 141 through the elastic bayonet. With the elastic tightening force of the elastic buckle 141, the above-mentioned pipette gun 13 is fixed to prevent the pipette gun 13 from falling during the movement of the entire device. The two elastic buckles 141 can clamp the pipette gun 13 more firmly. When the pipette gun 13 needs to be removed, the pipette gun 13 is held from the front side and a pulling force is applied to the front side to remove the pipette gun 13. In addition, three groups of the above-mentioned fixing brackets 14 are distributed from left to right on the inner wall of the rear side of the transparent plastic box 1. The sizes of the three groups of fixing brackets 14 are different, so that it is convenient to fix three groups of pipette guns 13 of different specifications in the transparent plastic box 1.

[0052] A third box body 15 is also clamped on the bottom of the transparent plastic box 1, and the third box body 15 is located at the right rear of the transparent plastic box 1. The top of the third box body 15 is penetrated to form a third opening. A third block body 16 is also provided in the third box body 15, and a third plug hole is opened on the top surface of the third block body 16. The gun tip 20 is inserted into the third plug hole, and the gun tip 20 is located in the third box body 15.

[0053] When the supernatant needs to be changed, the medical staff removes the pipette 13, takes out a gun tip 20, and then installs the gun tip 20 on the pipette 13. When the supernatant in a blood collection tube 9 is transferred, the gun tip 20 on the pipette 13 is removed. Alternatively, after the medical staff removes the pipette 13, the gun head of the pipette 13 is inserted into the third box body 15. The third box body 15 in this embodiment is a structural member made of transparent plastic. When the gun head of the pipette 13 is inserted into the third box body 15, the medical staff checks the gun head position from the outside so that the gun head is facing a gun tip 20, so that the gun tip 20 is installed on the gun head, and then lifts the pipette 13, so that the gun tip 20 on the gun head is taken out of the third box body 15. When the supernatant in a blood collection tube 9 is transferred, the gun tip 20 on the pipette 13 is removed.

[0054] In order to facilitate the collection of the removed pipette tip 20 13 , in the present embodiment, a fourth box body 17 is also clamped on the bottom of the transparent plastic box 1 , and the fourth box body 17 is located at the right front of the transparent plastic box 1 , and the top of the fourth box body 17 is penetrated to form a fourth mouth, and the used pipette tip 20 is discarded in the fourth box body 17 .

[0055] As a best implementation of this embodiment, in this embodiment, the first opening, the second opening, the third opening, and the fourth opening are all equipped with openable covers 18. When the supernatant needs to be transferred, the cover 18 of each opening is opened. When the supernatant is transferred, the cover 18 of each opening is closed. In this way, different covers 18 can be used to cover different openings, thereby preventing objects stored in the corresponding box body from flying out of the box body when the device is moved.

[0056] In order to prevent liquid from accumulating in the fourth box body 17 , in this embodiment, a sponge block 19 is installed on the bottom of the fourth box body 17 and the bottom surface of the cover plate 18 at the fourth opening, so that the sponge block 19 absorbs the liquid flowing out of the gun tip 20 .

[0057] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
