Description

Bone marrow preservation and preservation tube

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to marrow protect this storage tube.

Background

Bone marrow aspiration tests are commonly used to diagnose hematopoietic diseases, such as leukemia, and the aspirated bone marrow blood needs to be preserved in time for subsequent testing.

However, because some of the bone marrow blood of leukemia patients is in a high coagulation state, a blood clot may be coagulated during the process of extracting the bone marrow blood, and in addition, because the bone marrow itself is also a type of tissue, a doctor can extract a part of tissue clot-like substances during the bone marrow blood extraction, and the existing blood specimen storage tube has only a single tube body, and in the process of pouring the bone marrow blood specimen into the storage tube, the partially coagulated blood clot and the tissue clot-like substances are inevitably poured into the storage tube together for storage, so that the bone marrow blood in the storage tube is not pure enough during the subsequent examination, which affects the result of the laboratory test.

SUMMERY OF THE UTILITY MODEL

As a further improvement of the utility model, the filter screen is made of stainless steel.

As a further improvement, the outer wall of the lower pipe body is provided with an internal thread, and the internal thread is close to the filter screen.

As a further improvement of the utility model, the opening part of going up the body bottom is equipped with the external screw thread, the external screw thread with female connection.

As a further improvement of the present invention, the upper pipe body is close to the filter screen at the joint of the lower pipe body.

As a further improvement of the utility model, the inner wall of the lower tube body is coated with the anti-condensation liquid.

As a further improvement of the utility model, the pipe wall of the lower pipe body is provided with scales.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model discloses a through upper tube body, lower tube body that threaded connection is in the same place, lower tube body top is equipped with the filter screen, pours into from upper tube body top into when marrow blood sample to enter into the internal preservation of lower tube through the filter screen, the clot of coagulation then can be blockked by the filter screen during, makes the marrow blood sample of the internal preservation of lower tube purer.

2. The utility model discloses a scribble on the interior pipe wall of body down and prevent the lime set, prevent from getting into the internal marrow blood sample of body down and appearing the coagulation phenomenon from this.

Drawings

Fig. 1 is a schematic structural diagram of a preferred embodiment of the present invention.

In the figure, 100, a tube body is arranged; 101. an external thread; 110. a lower pipe body; 111. an internal thread; 120. filtering with a screen; 130. and (4) a pipe cap.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, the utility model provides a marrow book-keeping preservation tube, which is characterized in that comprises: an upper pipe body 100, a lower pipe body 110 and a filter screen 120.

The top and the bottom of the upper pipe body 100 are respectively provided with an opening, that is, the whole upper pipe body 100 is of a structure which is communicated up and down; lower body 110, it inwards stretches into from the opening part of upper tube body 100 bottom, pass through threaded connection between lower body 110 and the upper tube body 100, convenient to detach, and the top of lower body 110 is equipped with filter screen 120, inwards pour into from the upper tube body 100 top when the marrow blood sample, and enter into through filter screen 120 and preserve in the lower body 110, the clot of blood that coagulates during this period then can be blockked by filter screen 120, make the marrow blood sample of preserving in the body 110 purer under the entering, and when the clear marrow blood sample in the body 110 is extracted to needs, as long as with last body 100 demolish can, whole operation process is simple and convenient, the purity of the marrow blood sample of preserving in the lower body 110 has been guaranteed simultaneously.

Preferably, the opening at the top of the upper tube 100 is provided with the tube cap 130, which can prevent dust and impurities in the air from entering the tube and polluting the blood, and the tube cap 130 is preferably made of rubber, when the marrow blood specimen is required to be injected into the tube, the injection tube is only required to be inserted inwards from the tube cap 130 for injection, and since the injection tube is opposite to the strainer 120 during injection, most of the marrow blood specimen can directly enter the lower tube 110 after being filtered by the strainer 120, and the coagulated blood clot is left on the strainer 120.

Preferably, the filter 120 is made of stainless steel, and the aperture of the filter 120 is small, so that the bone marrow blood sample can smoothly enter the lower tube 110 through the filter 120, and at the same time, the filter 120 can block the coagulated blood clot, so as to ensure that the separation degree of the blood from the blood clot is high, thereby ensuring that the bone marrow blood sample in the lower tube 110 has good purity.

Preferably, the outer wall of the lower pipe body 110 is provided with an internal thread 111, and the internal thread 111 is close to the filter screen 120, that is, the internal thread 111 is close to the top of the lower pipe body 110, and the opening at the bottom of the upper pipe body 100 is provided with an external thread 101, and the external thread 101 is connected with the internal thread 111, thereby realizing the detachable connection between the upper pipe body 100 and the lower pipe body 110.

Preferably, the inner wall of the lower tube body 110 is coated with the anti-coagulation liquid, after the anti-coagulation liquid is coated, the problem that the marrow blood specimen in the lower tube body 110 is coagulated into blood clots can be guaranteed, and meanwhile, when the marrow blood specimen dripped into the lower tube body 110 splashes onto the inner wall of the lower tube body 110, the splashed marrow blood specimen can smoothly slide down along the inner wall, so that the coagulation condition can not occur, and the purity of the marrow blood specimen in the lower tube body 110 is guaranteed.

Preferably, the lower tube body 110 has a scale on the wall thereof, so that the doctor can conveniently observe how many bone marrow blood samples are stored in the lower tube body 110.

The technical means disclosed by the scheme of the utility model is not limited to the technical means disclosed by the technical means, but also comprises the technical scheme formed by the arbitrary combination of the technical characteristics. The above is a detailed implementation manner of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
