The new hematology bone marrow puncture needle according to the embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

1 to 3 , a new hematology bone marrow puncture needle provided according to an embodiment of the utility model includes a positioning component 10 , a hemostatic compression component 20 and a bone marrow puncture component 30 .

The positioning component 10 includes an adhesive plate 11 and a connecting tube 12. The adhesive plate 11 is suitable for being attached around the puncture port. The lower surface of the adhesive plate 11 can be provided with latex or other medical colloids with good adhesive effects, so that the adhesive plate 11 can be firmly adhered to the skin. A through hole is provided in the middle of the adhesive plate 11, through which a part of the skin can be exposed, and this position can be used as the puncture port. The connecting tube 12 is provided on the upper surface of the adhesive plate 11 and is connected to the through hole. In this way, the through hole and the connecting tube 12 can be opposite to the puncture port to facilitate puncture.

The hemostatic compression component 20 includes a connecting seat 21 and a hemostatic seat 22. The connecting seat 21 is movably connected to the connecting tube 12 and is used to install the hemostatic seat 22 in the connecting tube 12 and drive the hemostatic seat 22 to move downward in the connecting tube 12 to compress the puncture port.

That is to say, the connecting seat 21 can install the hemostatic seat 22 in the connecting tube 12, and the connecting seat 21 can drive the hemostatic seat 22 to move downward along the channel formed by the through hole and the connecting tube 12, so that the hemostatic seat 22 can contact the puncture port and press the puncture port, thereby playing a role in hemostasis.

The bone marrow puncture assembly 30 includes a needle body 31 and a needle core 32. The needle body 31 is detachably disposed on the connecting seat 21 and opposite to the through hole for puncturing the bone marrow. The needle core 32 is disposed in the needle body 31 for aspirating the bone marrow.

The needle body 31 can be installed on the connection seat 21, so that it approaches the skin along the connection seat 21 and the through hole, and penetrates into the patient's body through the through hole until it punctures the bone marrow, and then the bone marrow is sucked out by the needle core 32. During this process, the needle body 31 always moves inside the connection seat 21, so the connection seat 21 can guide the needle body 31, so that during the puncture process, the needle body 31 will not tilt and thus deviate. The needle body 31 can also be removed from the connection seat 21, so that the hemostatic compression component 20 can be exposed, so that it is easy to operate the hemostatic compression component 20 to stop bleeding at the puncture site.

More specifically, when in use, the doctor can determine the puncture site on the patient's skin surface, and then move the entire application close to the selected puncture site, so that the adhesive plate 11 is adhered around the selected puncture site. Further, the needle body 31 is driven to puncture the selected puncture site along the connecting seat 21 and the through hole until the needle body 31 penetrates into the bone, and the needle core 32 can be used in conjunction with the negative pressure member to absorb the bone marrow. In the above puncture process, since the positioning assembly 10 is adhered to the skin and the needle body 31 moves along the connecting seat 21, the connecting seat 21 can guide the needle body 31. Therefore, even if the medical staff's hands shake, the needle body 31 will not deviate, thereby ensuring the accuracy of the puncture. After the bone marrow aspiration is completed, the needle body 31 can be withdrawn from the patient's body and then removed from the connecting seat 21. At this time, the hemostatic compression component 20 can be exposed, which makes it convenient for medical staff to control the connecting seat 21 to drive the hemostatic seat 22 to approach the puncture port and compress the puncture port. In this way, the compression hemostasis effect can be achieved, and the pressing force can be adjusted. When stopping bleeding, there is no need for the patient or medical staff to press manually, which is very convenient.

According to the new hematology bone marrow puncture needle provided by the utility model, on the one hand, it can be attached to the skin to guide the puncture and prevent the puncture angle from changing; on the other hand, the puncture site can be compressed after the puncture to achieve a hemostatic effect.

Advantageously, in one embodiment of the present utility model, the connection seat 21 includes a first annular connection piece 211 and a top plate 212; the first annular connection piece 211 is threadedly connected to the connection pipe 12;

The top plate 212 is disposed at the upper end of the first annular connecting member 211 , and the hemostatic seat 22 is disposed in the first annular connecting member 211 and connected to the top plate 212 .

Preferably, the hemostatic seat 22 includes a connecting rod 221 and a hemostatic patch 222; the upper end of the connecting rod 221 is connected to the top plate 212;

The hemostatic patch 222 is disposed at the lower end of the connecting rod 221;

When the connecting seat 21 rotates along the connecting tube 12, the connecting seat 21 drives the connecting rod 221 to move downward, so that the hemostatic patch 222 passes through the through hole and presses the puncture port.

That is to say, the connecting seat 21 is generally a cover-like structure, which can be threadedly connected to the connecting tube 12, so that it can rotate downward along the connecting tube 12 to drive the hemostatic seat 22 therein to rotate downward and compress the puncture port. In this way, the hemostatic patch 222 can be pressed on the puncture port, thereby compressing the puncture port to stop bleeding. Moreover, after the connecting seat 21 is moved into place, it also has a self-locking function, so that the hemostatic patch 222 can maintain pressure on the puncture port to ensure the hemostatic effect. At the same time, by adjusting the connecting seat 21 up and down, the pressure of the hemostatic patch 222 on the puncture port can be adjusted, which is convenient for use.

Advantageously, in some embodiments of the present invention, the needle body 31 includes a syringe 311 and a puncture member 312; a second annular connecting member 2121 is provided on the upper surface of the top plate 212, and the syringe 311 is threadedly connected to the second annular connecting member 2121;

The piercing member 312 is threadedly connected to the syringe 311 , and the needle core 32 is disposed in the piercing member 312 .

In this way, the syringe 311 is detachably connected to the connection base 21 through the second annular connection piece 2121, so that it can be disassembled after the puncture is completed, so that the compression hemostasis component can be used to compress and stop bleeding at the puncture site. The syringe 311 is threadedly connected to the puncture piece 312 inside it, so that the puncture piece 312 can be spirally rotated, thereby generating a large force on the bone along the connection base 21, so that it can pass through the bone and contact with the bone marrow to complete the puncture, and then use the needle core 32 to absorb the bone marrow.

Advantageously, in some embodiments of the present invention, a groove 2122 is provided in the middle of the upper surface of the top plate 212 , the groove 2122 extends vertically to the lower end of the connecting rod 221 , and an avoidance hole is provided on the bottom wall of the groove 2122 , the avoidance hole being used to avoid the piercing member 312 .

Preferably, in some embodiments of the present invention, an annular liquid storage capsule 2123 is provided on the groove wall of the groove 2122 , and disinfectant is provided inside the annular liquid storage capsule 2123 .

The disinfectant can be alcohol or hydrogen peroxide, which has a good disinfection effect. It is installed in the annular liquid storage bag 2123. Then, during puncture, the puncture member 312 can pass through the middle of the annular liquid storage bag 2123 and puncture into the bone along the avoidance port without affecting the annular liquid storage bag 2123. When the puncture is completed and the puncture assembly is removed, the annular liquid storage bag 2123 can be exposed. At this time, the annular liquid storage bag 2123 is punctured, and the disinfectant therein can flow into the hemostatic patch 222 along the avoidance port, thereby contacting the puncture port to disinfect the puncture port.

Advantageously, in some other embodiments of the present invention, an inverted U-shaped handle 3121 is disposed at the upper end of the piercing member 312 , and the inverted U-shaped handle 3121 is used to drive the piercing member 312 to rotate.

The inverted U-shaped handle 3121 can facilitate medical staff to operate the puncture member 312, and then control the puncture member 312 to rotate in the inner thread of the syringe 311, thereby allowing the needle tip of the puncture member 312 to spirally penetrate the bone surface and contact the bone marrow, so as to facilitate the use of the needle core 32 to absorb the bone marrow.

Advantageously, in some other embodiments of the utility model, a plurality of scale lines 3111 are evenly spaced from top to bottom on the outer wall of the syringe 311, and a plurality of scale values are provided corresponding to the scale lines 3111, and these scale values are 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, etc. from top to bottom.

In this way, when the inverted U-shaped handle 3121 is used to control the puncture member 312 to rotate downward, the inverted U-shaped handle 3121 can move downward along the syringe 311, so that the two ends of the inverted U-shaped handle 3121 can be matched with the scale lines 3111 at the corresponding positions, and the downward movement distance of the inverted U-shaped handle 3121 can be read according to the scale value. Therefore, in this way, the puncture depth of the puncture member 312 can be read in real time.
