Background
The tears have lubricating, moisturizing, repairing and antibacterial effects and have important effects on the health of cornea. When tear secretion is abnormal, the cornea will be damaged progressively and continuously, causing various degrees of ocular surface disease. Clinically conventional therapies are the use of artificial tears, punctal occlusion, keratology bandages, and the like. Although these treatments have some efficacy, they do not provide the growth factors, vitamins and immunoglobulins needed to repair the cornea, and still do not address some of the intractable ocular surface lesions. The use of Autologous Serum (AS) to treat diseases of the surface of the eye has been conceived AS early AS 1970.
Traditional serum preparation requires the extraction of a certain amount of venous blood from a patient and the centrifugation to obtain serum. Because of the need of a centrifuge and electric power, the process is complicated, the time consumption is long, the microbial contamination is very easy to cause in the operation process, and the method is not suitable for extracting a small amount of serum in clinical ophthalmology, so that the clinical application is greatly limited.

The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.
According to the utility model, as the syringe sucks blood through the suction needle, blood cells are covered by the filter element in the suction needle, so that serum can be quickly obtained, and the serum extraction amount is increased.
In order that the above-described aspects may be better understood, exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the utility model to those skilled in the art.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
As described in the background art, tears prepared from autologous serum have an irreplaceable effect compared to other means, but conventional serum preparation requires that a certain amount of venous blood of the patient be withdrawn and serum be obtained by centrifugation. Because of the need of a centrifuge and electric power, the process is complicated, the time consumption is long, the microbial contamination is very easy to cause in the operation process, and the method is not suitable for extracting a small amount of serum in clinical ophthalmology, so that the clinical application is greatly limited. The patient can hardly obtain the effective treatment mode in the places other than the medical laboratory, and the technical proposal of the utility model aims to provide a device which can simply and quickly prepare a small amount of autologous serum
Fig. 1 to 3 show an autologous serum preparation apparatus, syringe 1, according to an embodiment of the present utility model: a push rod 11 is movably arranged in the needle cylinder 1, a rubber plug 12 is arranged at one end of the push rod 11, and the push rod 11 pushes the rubber plug 12 to move in the needle cylinder 1 so as to generate a negative pressure area in the needle cylinder 1; the other end forms an expansion end 13 which is convenient to press; the device has the advantages that a small amount of blood is filtered by the filter element 21, substances such as red blood cells and white blood cells in the blood are removed, and serum is directly obtained, so that in the traditional medical experiment, the blood needs to be quickly layered by a centrifugal machine, but when the push rod 11 of the needle cylinder 1 moves outwards, a negative pressure environment is produced, the blood is forced to accelerate to pass through the filter element 21, and serum is obtained, therefore, the needle cylinder 1 of the device adopts a thick wall similar to a micro-syringe structure, the capacity of an internal cavity is not required to be too large, the push rod 11 is also very thin, so that a trace amount of liquid is absorbed, the push rod 11 can have a larger stroke, and the operation requirement on ordinary people is reduced.
Aspiration needle 2: one end of the hollow structure is a connecting section connected with the needle cylinder 1, a filter element 21 is arranged in the connecting section, and the other end of the hollow structure is open, so that a negative pressure area in the needle cylinder 1 is communicated with an external space through the hollow structure; the aspiration needle 2 in the present device is also a tubular structure of small diameter, and as mentioned above, the quantity of autologous serum produced is not required to be great, and the thicker needle itself will contain more blood, making the stroke of the push rod 11 too long.
In some embodiments, the open end of the aspiration needle 2 is a blunt needle, and the device is not used by inserting the needle directly into a blood vessel to draw blood, so that the sharpened needle is not required to provide a piercing force, and the possibility of a person being stabbed or scratched during operation can be reduced by using the blunt needle.
The needle can be detachably connected with the needle cylinder 1 in the mode shown in fig. 2, so that the split sterilization is convenient, the connection part of the needle and the needle is used for placing the filter element 21, but in some embodiments, the filter element 21 is fixedly arranged in the suction needle 2, the complexity of the device in use can be effectively reduced by adopting an integrated design, and the problem that the filter effect is poor due to the fact that the filter element 21 is not placed in place in the process of placing can be avoided.
The needle can be further decomposed into a needle tube 22 and a needle tube seat 23, as shown in fig. 2 and 3, and the design structure aims at solving the problems in processing and use with lower cost if the needle tube 22 is an elongated cylinder, the processing difficulty is high, the cost is high, and the needle tube is blocked (blocked by blood clots due to untimely cleaning) or is bent or fails in use.
Filter element 21: the particle diameter of the filter is 0.8-0.9 mu m; this filter particle size is smaller than the red blood cells (diameter not smaller than 7 μm) and white blood cells (diameter not smaller than 7 μm) and platelets (diameter not smaller than 1 μm) in blood, while only serum is retained, optionally, the filter element 21 is detachably provided in the suction needle 2 for easy replacement, and a specific placement position is a position between the needle and the cylinder 1 for easy placement, and for easy replacement by a user and for reducing the suction process discomfort caused by clogging of the filter paper, the filter paper may be processed into a circular shape having a diameter of 3 to 5 mm.
In some embodiments, the filter element 21 is glass fiber paper, and from the standpoint of availability and overall cost, glass fiber filter paper is preferred, and the specific specification of the filter paper may be the WHATMAN GF/F glass fiber filter paper series 0.7um pore size 1825-xxx, which may be cut to a size that allows for placement of the suction needle 2 according to the specifications of the present utility model.
When the device is used, the device is operated according to the following steps: the alcohol disinfection refers to the skin of abdomen, and the disposable blood taking needle head punctures the skin to obtain round blood drop. By using the device to suck 2 drops of blood, blood cells and fibrinogen are filtered by the filter element 21, and serum is sucked into the syringe 1, thereby achieving the purpose of blood separation. And then the serum is injected into an empty eyedrop bottle to prepare the eyedrop containing autologous serum, compared with the traditional serum separation and extraction technology, the serum separation process is simplified, the method is convenient and quick, and a patient does not need to go to a hospital and can finish preparation at home.
