Description

Technical Field

[0001] This utility model relates to the field of medical accessory technology, specifically to a bone marrow puncture device. Background Technology

[0002] Bone marrow aspiration is a common clinical diagnostic technique, primarily used to examine the morphology and cellular composition of bone marrow to aid in the diagnosis of various hematologic disorders and other related diseases. Bone marrow aspiration is frequently used to diagnose hematologic disorders such as anemia, leukemia, and myelodysplastic syndromes, as well as other conditions such as infectious diseases and certain neoplastic diseases.

[0003] In existing techniques, except for infant patients and patients with excessive weight, the anterior superior iliac spine is usually used for puncture. This location has a relatively flat bone surface, is easy to fix, and is convenient and safe to operate on, making it one of the preferred sites for bone marrow aspiration. During the puncture, the patient is placed in a supine position, and medical staff help the patient adjust to a suitable position to ensure comfort and ease of operation. Then, the puncture point is marked 1-2 cm posterior to the anterior superior iliac spine with a marker pen or gentian violet to ensure accuracy during the puncture. Finally, disinfection is performed. After anesthesia, the puncture point needs to be reconfirmed. In practice, the disinfection and anesthesia processes can affect the marking point, making it unclear. The use of marker pens has limitations and can adversely affect the puncture process, indicating room for technical improvement. Utility Model Content

[0004] This invention aims to solve the aforementioned technical problem that the disinfection and anesthesia process can affect the marking points, causing them to become blurred, and provides a bone marrow puncture device.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a bone marrow aspiration device, including a detachable puncture needle and a positioning component; the puncture needle includes a needle body and a gripping part;

[0006] The positioning component includes an outer shell, a column below the outer shell, a soft suction cup below the column, and the soft suction cup is attached to the skin at the puncture site; a micro battery module is located inside the outer shell.

[0007] A connector is provided on one side of the outer shell, and a positioning block is rotatably connected to the side of the connector away from the outer shell. The positioning block is provided with a through groove that can accommodate the needle body. Several LED beads are provided below the positioning block and along the circumference of the through groove.

[0008] Furthermore, the outer side of the grip portion is provided with several annular anti-slip grooves.

[0009] Furthermore, the length of the column ranges from -mm.

[0010] Furthermore, the soft suction cup is made of silicone; the edges and corners of the outer shell and positioning block are rounded.

[0011] Furthermore, the micro battery module is connected with a wire that extends into the positioning block and is electrically connected to the LED beads.

[0012] Furthermore, the positioning block has a mounting plug on one side, the connector has a groove on the side that can accommodate the mounting plug, and a long screw is provided between the connector and the mounting plug, with one end of the long screw extending out of the connector and locked by a nut.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] Positioning is achieved through a soft suction cup, column, outer shell, and matching light bulb that can be fixed near the puncture site. A light ring can be formed at the final puncture site, and the needle can be inserted inside the light ring. The light ring can be disinfected normally without affecting the use.

[0015] After adsorption and positioning, the positioning position can still be finely adjusted by adjusting the tilt angle of the positioning block, making it flexible to use; it can also limit the needle body, so that it goes down in the direction of the through groove, avoiding hand tremors.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Example 1, in conjunction with Appendix Figure 1 , 2 A bone marrow aspiration device includes a detachable puncture needle and a positioning component; the puncture needle includes a needle body 1 and a grip 2, and the outer side of the grip 2 is provided with a plurality of annular anti-slip grooves to increase friction when gripped and prevent slippage.

[0022] Combined with appendix Figure 1 , 2The positioning component includes an outer shell 3, with a column 4 located below the outer shell 3. The length of the column 4 ranges from 60 to 100 mm. If it is too short, it will affect the line of sight to the needle body 1 when inserting the needle; if it is too long, it will reduce the support or affect the downward movement of the grip part 2. A soft suction cup 5 is located below the column 4. The soft suction cup 5 is attached to the skin at the puncture site. The soft suction cup 5 is made of silicone to improve softness and avoid causing discomfort to the patient's skin. The edges and corners of the outer shell 3 and the positioning block 7 are rounded, making the overall structure rounded without right angles and sharp corners, so as to avoid rubbing against the patient's skin when placed or tilted.

[0023] In addition, a micro battery module is provided inside the outer shell 3; the micro battery module is connected to a wire 11, which extends into the positioning block 7 mentioned below and is electrically connected to the lamp bead 10, so that the lamp bead 10 emits light and forms a ring of light on the patient's skin to locate the puncture site, and subsequent disinfection will not affect it.

[0024] Combined with appendix Figure 1 , 2 3. A connector 6 is provided on one side of the outer shell 3. A positioning block 7 is rotatably connected to the side of the connector 6 away from the outer shell 3. A through groove 8 is provided on the positioning block 7 to accommodate the needle body 1. Several LED beads 10 are provided below the positioning block 7 and along the circumference of the through groove 8.

[0025] According to the above, the positioning block 7 has a mounting block 12 on one side, and the connector 6 has a groove on the side that can accommodate the mounting block 12. A long screw 13 is provided between the connector 6 and the mounting block 12. One end of the long screw 13 extends out of the connector 6 and is locked with a nut. Thus, in the above structure, when the soft suction cup 5 has been positioned but the positioning position needs to be finely adjusted, the nut is slightly loosened, so that the positioning block 7 and the mounting block 12 rotate relative to the connector 6, and the position of the lamp ring follows the rotation, thereby achieving fine adjustment and improving the flexibility of use.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
