Description

Technical Field

[0001] This utility model relates to the field of serum separation technology, and in particular to a disposable blood collection serum separator. Background Technology

[0002] Serum is the pale yellow, transparent liquid formed from the liquid portion of blood during the clotting process. It contains many important biochemical components. Serum tests can provide detailed information about a patient, including indicators of blood composition, metabolic function, inflammation level, and immune response. Serum tests are widely used in the diagnosis, prevention, treatment, and monitoring of diseases. Doctors can analyze the biochemical indicators in serum to determine whether a patient has a certain disease or abnormal pathophysiological process.

[0003] Currently, the disposable serum separators used in hospital laboratories mainly consist of a dropper orifice, a pressure cap, and a sample reservoir. After adding whole blood to the dropper orifice, the pressure cap is closed and pressed, causing the serum to pass through the inner membrane at the bottom of the dropper orifice under pressure and enter the sample reservoir. The serum is then drawn from the reservoir using a dropper for testing. This separator requires two drops: one to draw whole blood into the dropper orifice, and another to draw serum from the sample reservoir. It cannot directly add the separated serum to the test tube, making it inconvenient to use. Furthermore, after use, the top of the dropper orifice is sealed by the pressure cap, but the sample reservoir is open, which can easily contaminate the environment when the separator is subsequently recycled. Therefore, to address these shortcomings, this invention proposes a disposable blood collection serum separator. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a disposable blood serum separator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a disposable blood serum separator, comprising a separator cylinder, wherein the top of the separator cylinder is open and the bottom of the separator cylinder is provided with a drainage channel, an inner membrane is fixed at the bottom of the separator cylinder, a pressure cap is slidably connected to the top of the separator cylinder, two symmetrical side support plates are fixed at the top of the outer wall of the separator cylinder, an annular plate is fixed on the bottom surface of the separator cylinder, and the surface of the annular plate is provided with external threads, and a bottom cover is rotatably connected to the surface of the annular plate through the threads.

[0006] Furthermore, the inner diameter of the drainage channel is smaller than the inner diameter of the separation cylinder.

[0007] Furthermore, a top plate is fixedly connected to the top of the pressure cap, and the size of the top plate is larger than that of the pressure cap and the separation cylinder.

[0008] Furthermore, the top plate surface and the outer wall of the separation cylinder are fixedly connected by a connecting strip.

[0009] Furthermore, a liquid guide bucket is fixed inside the separation cylinder and above the inner membrane, and a drip hole is provided at the bottom of the liquid guide bucket.

[0010] Furthermore, the outer wall of the bottom cover is provided with anti-slip texture, and an annular groove is opened at the top of the side wall of the bottom cover, with a sealing ring snapped into the annular groove.

[0011] Furthermore, a suction cup is fixedly connected to the lower surface of the bottom cover.

[0012] The beneficial effects of this utility model are:

[0013] 1. When using this utility model, the disposable blood collection serum separator is equipped with a separation cylinder, a drainage channel, an inner membrane, a pressure cap, and a side support plate. After whole blood is dripped into the separation cylinder, two fingers can be placed on the lower surface of the side support plate, and then the pressure cap can be pressed with the thumb, so that the serum at the separation point can be directly discharged from the drainage channel. There is no need to use a dropper to draw up the separated serum a second time, making it more convenient and faster to use.

[0014] 2. When in use, this disposable blood collection serum separator is equipped with a separation cylinder, an annular plate, and a bottom cover. The bottom cover can support the separation cylinder, making it easy to add whole blood into the separation cylinder through a dropper. After the separator is used up, the bottom cover is tightened onto the surface of the drainage channel at the bottom of the separation cylinder to seal the bottom of the separation cylinder and prevent recycling contamination.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a disposable blood serum separator is disclosed, comprising a separator cylinder 1 with an open top and a drainage channel 2 at the bottom. An inner membrane 3 is fixed to the bottom of the separator cylinder 1, and a pressure cap 4 is slidably connected to the top of the separator cylinder 1. Two symmetrical side support plates 7 are fixed to the top of the outer wall of the separator cylinder 1. An annular plate 10 is fixed to the bottom surface of the separator cylinder 1, and the surface of the annular plate 10 is provided with external threads. A bottom cover 11 is rotatably connected to the surface of the annular plate 10 through the threads.

[0023] The inner diameter of the drainage channel 2 is smaller than the inner diameter of the separation cylinder 1.

[0024] However, after the serum in the whole blood is separated through the inner membrane 3, because the inner diameter of the drainage channel 2 is very small, too much serum will not be discharged at once, thus making it easy to slowly drip the discharged serum into the test tube.

[0025] The top of the pressure cap 4 is fixedly connected to a top plate 5, and the size of the top plate 5 is larger than that of the pressure cap 4 and the separation cylinder 1.

[0026] By setting the top plate 5, the pressure cover 4 is prevented from getting stuck inside the separator cylinder 1 and being unable to be pulled out.

[0027] The top plate 5 and the outer wall of the separation cylinder 1 are fixedly connected by a connecting strip 6.

[0028] The top plate 5 and pressure cover 4 can be prevented from being lost by setting the connecting strap 6.

[0029] Inside the separator 1 and above the inner membrane 3, a liquid guide hopper 8 is fixed, and a drip hole 9 is provided at the bottom of the liquid guide hopper 8.

[0030] After adding whole blood into the separator 1, the whole blood will pass through the drip hole 9 and fall onto the surface of the inner membrane 3. Then, the separator 1 needs to be shaken so that the whole blood completely covers the inner membrane 3. At this time, the liquid guide 8 and the reduced drip hole 9 can prevent the blood from flowing upward when shaking.

[0031] The outer side wall of the bottom cover 11 is provided with anti-slip texture, and the top of the side wall of the bottom cover 11 is provided with an annular groove 13, and a sealing ring 14 is engaged inside the annular groove 13.

[0032] The bottom cover 11 can be directly screwed onto the surface of the annular plate 10. The anti-slip texture can prevent slippage when screwing the bottom cover 11, and the sealing ring 14 can increase the sealing between the bottom cover 11 and the annular plate 10 to prevent serum leakage.

[0033] A suction cup 12 is fixedly connected to the lower surface of the bottom cover 11. By setting the suction cup 12 to adhere to the table, the bottom cover 11 can be placed stably.

[0034] Working principle: First, fix the suction cup 12 to the table. Then, pull the pressure cap 4 out of the separation cylinder 1. Next, add whole blood into the separation cylinder 1 through the dropper. The whole blood passes through the dropper hole 9 and falls onto the surface of the inner membrane 3. Then, lift the bottom cap 11 from the table and unscrew it from the surface of the annular plate 10. Slightly shake the separation cylinder 1 to ensure the blood completely covers the inner membrane 3. After standing for the specified time, insert the pressure cap 4 into the separation cylinder 1. Then, place your index and middle fingers on the lower surfaces of the two side support plates 7, and your thumb on the surface of the top plate 5. Place the drainage channel 2 above the test tube and squeeze the top plate 5, causing the pressure cap 4 to move along the inside of the separation cylinder 1. Under pressure, the serum in the blood passes through the inner membrane 3 and is discharged from the drainage channel 2 directly into the test tube. Finally, screw the bottom cap 11 back onto the surface of the annular plate 10 for recycling.

[0035] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
