Description

Vacuum Blood Collection System {Vacuum Blood Collection System}

The present invention relates to a vacuum blood collection device, and more particularly to a vacuum blood collection device that informs the collection time and the vacuum blood vessel that can remove residual fibers after serum separation and minimizing pain and the assembly of the needle assembly is very easy to assemble.

Conventional vacuum blood vessels do not have a time display function, and the remaining fibers are resuspended, preventing the probe of expensive medical equipment and causing a breakdown.

In addition, when the needle moves into the body or moves around or finds blood vessels immediately, the upper part of the needle turns to suffer from poor blood collection. When assembling, the assembly was inconvenient because it had to be rotated about one to two wheels.

The purpose of the present invention devised to solve the above problems is to display the time for the bleeding time elapsed, easy to use and improve the accuracy of the test, as well as to reduce the pain during blood collection To provide.

Vacuum collection apparatus of the present invention for achieving the above object forms a time display point for setting the blood collection time in the groove of the rubber stopper, attaching the time display label to indicate the time on the outer wall of the test tube, the silicon and silicon on the inner wall of the test tube It consists of a vacuum-coated tube coated with particles, and a plastic needle supporting the upper and lower needles, indicating the needle top mark so that the top of the needle can be inserted into the pad, and forming a threaded needle assembly for connecting with the cylinder. It is characterized by.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a vacuum blood vessel of the present invention.

As shown in Figure 1, the vacuum collection tube 100 of the present invention consists of a rubber stopper (1) and the test tube (5).

The rubber stopper (1) has formed a time mark (3) in which the blood collection time is set in the groove (2) or the protruding portion and the groove (2) in order to prevent slipping when opening. Rubber material was used so as not to go.

The test tube (5) has a time label (4) marked on the surface of the test tube, and coated with silicon (7) on the inner wall to prevent blood from being buried, and coated with silicon (to promote the coagulation of blood). The silicon particles 6 were sprayed onto 7) and coated.

When the blood is collected in the test tube (5) and the rubber stopper (1) is turned on the time display label (4) marked with time, the time display point (2) is set and the examiner can see what time the blood is collected. For example, if a patient's sample was collected at 10 pm yesterday evening, 2 am today, and 6 am yesterday, Hong Gil-dong will be 3 in the morning test and there is a risk that the order will be reversed. There is no concern.

The silicone gel (9) and the cured silicone gel (8) were made by curing the silicone gel (9) and the silicone in a test tube (5) and having an irregular and tortuous shape. Because it blocks between and serum, only serum can be collected and tested. Here, the cured silicone gel (8) is located below the serum than the silicone gel (9), because it serves to hold the remaining fibers do not resuspend can prevent the failure of expensive medical equipment, specific gravity 25 It is about 1.03-1.07 which is slightly larger than water at ℃.

If necessary, the silicon (7), the silicon gel (9) and the cured silicone gel (8) formed on the inner wall of the test tube (5) can be removed, and various anticoagulants and cell and gene preservatives can be used for use. .

Figure 2 is a cross-sectional view of the stopper coupled to the vacuum blood vessel of the present invention.

As shown in Fig. 2, the rubber stopper 1 has a test tube inserting portion 11 inside, which blocks the entrance of the test tube 5 and wraps it on the outside, thereby preventing blood from getting on the hand.

3 is a front view of the needle assembly according to the present invention, Figure 4 is an external view of a cylinder for coupling the needle assembly according to the present invention.

As shown in FIG. 4, the needle assembly 200 is supported by the upper needle 21 and the lower needle 26 by a plastic support 22 capable of viewing blood flow using a transparent or translucent material. . Here, the upper needle 21 may be used by coating the silicon to reduce the pain during blood collection, the lower needle 26 is protected with a rubber cover 25 and maintained in a vacuum.

The plastic support 22 has a needle top marking point 23 so as to know the direction of the needle top even after the upper needle 21 enters the body for blood collection, and is connected to the cylinder 30 of FIG. 5. The thread 24 is formed.

Since the thread 24 can be assembled at one time without removing the rotation angle between 90 ° and 360 °, the assembly time can be shortened. The lower part without the thread 24 fits tightly into the cylinder 30 so that the needle does not shake. Here, the needle assembly 200 is coupled to the upper cap 27 and the lower cap 28 to be stored.

The present invention as described above, the vacuum blood vessel can be displayed the time to check the elapsed time from the blood collection to the test, and not only chaos can be inspected several vacuum blood vessels per time zone of one patient as well as remaining after serum separation Because it prevents resuspension of fibrin, there is an advantage of providing a serum that can be accurately tested.

In addition, the needle assembly can be easily assembled due to the low number of revolutions, there is an indication point on the top of the needle is convenient to use and has the effect of reducing pain when collecting blood.
