Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a bone marrow aspiration device for leukemia patients. Background Technology

[0002] Bone marrow aspiration is an indispensable key technique for diagnosing and monitoring hematologic diseases such as leukemia. By extracting a small amount of bone marrow fluid, cellular morphology, immunology, genetics, and molecular biology analyses are performed, providing decisive evidence for disease classification, prognosis, and treatment planning.

[0003] Currently, the bone marrow aspiration devices widely used in clinical practice mainly rely on the traditional manual operation mode. Their core components are usually only a bone aspiration needle and a connected large-capacity (usually 10-20mL) syringe. This operation process depends entirely on the doctor's personal experience and feel, and has the following inherent defects:

[0004] During bone marrow extraction, the doctor first inserts a bone-piercing needle into the body and reaches the appropriate position. Then, the needle core is removed from the bone-piercing needle, and a syringe is installed to extract the bone marrow. This method involves many movements by the doctor, and the bone-piercing needle is prone to shaking, which can cause deviations and affect the effectiveness of bone marrow extraction. It also increases the patient's pain. Summary of the Invention

[0005] The purpose of this invention is to provide a bone marrow aspiration device for leukemia patients, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to a bone marrow aspiration device for leukemia patients, comprising an extraction needle for puncturing and extracting bone marrow from the patient. A reinforcing mechanism is provided outside the extraction needle, consisting of an adhesive component and a limiting component. The adhesive component is used to adhere and fix the entire reinforcing mechanism to the patient's skin. The limiting component consists of a fixing sleeve and an adjusting sleeve. The fixing sleeve is connected to the adhesive component, and the adjusting sleeve is fitted onto the fixing sleeve. The fixing sleeve has a locking base, and the adjusting sleeve has a locking kit. The locking base and locking kit work together to lock and fix the extraction needle.

[0008] Furthermore, a semicircular plate is slidably mounted on the fixed sleeve, and a locking base is set on the semicircular plate. The locking base consists of multiple locking strips arranged in a ring. The locking strips are deformable. The locking kit consists of a locking ring and a connecting rod. The locking ring is located below the locking base, and the connecting rod is mounted on the locking ring. One end of the connecting rod is rotatably connected to the adjusting sleeve.

[0009] Furthermore, the top of the locking ring is designed in a bucket shape.

[0010] Furthermore, the adhesive assembly consists of an adjusting plate and an adhesive plate. The adjusting plate is mounted on the fixed sleeve, and the adhesive plate is rotatably mounted on the adjusting plate. An adhesive medium is provided on one side of the adhesive plate.

[0011] Furthermore, the fixing sleeve is provided with a wound covering, which is used to cover and adhere the wound after the extraction needle is removed. The adjusting sleeve is provided with an adjusting component, which is used to adjust the position of the wound covering.

[0012] Furthermore, the wound covering is composed of a wound dressing plate, with medical medication placed at the bottom of the wound dressing plate. The adjusting component consists of an arc-shaped strip, an adjusting rod, and an abutment head. The arc-shaped strip is located at the top of the wound dressing plate, and a groove is formed at the top of the arc-shaped strip. The inner wall of the bottom of the groove is set as a slope. The adjusting rod is slidably mounted on the adjusting sleeve, and the abutment head is installed at the bottom end of the adjusting rod. The abutment head extends into the groove and contacts the slope.

[0013] Furthermore, a connecting block is installed inside the fixing sleeve, and an arc-shaped rod is installed on the connecting block. A sliding block is installed on the top of the wound dressing plate. The arc-shaped rod passes through the sliding block and is slidably connected to the sliding block. An arc-shaped spring is sleeved on the arc-shaped rod. One end of the arc-shaped spring is connected to the corresponding connecting block, and the other end of the arc-shaped spring is slidably connected to the sliding block.

[0014] Furthermore, both the fixing sleeve and the adjusting sleeve are made of transparent acrylic material.

[0015] Furthermore, the connecting rod adopts a segmented structure, with the upper segment being connecting support rod one and the lower segment being connecting support rod two. A connecting cylinder is provided at the top of connecting support rod two, and the bottom end of connecting support rod one extends into the connecting cylinder and is slidably connected to the connecting cylinder. A sliding disc is installed at the bottom end of connecting support rod one, and the sliding disc is slidably connected to the inner wall of the connecting cylinder. A reinforcing spring is sleeved on connecting support rod one, with the bottom end of the reinforcing spring connected to the sliding disc and the top end of the reinforcing spring connected to the inner wall of the connecting cylinder. A rack plate one is slidably installed on the adjusting sleeve, and a rack plate two is installed on the top of the semi-circular plate. A connecting gear is rotatably installed on the fixed sleeve, and the connecting gear meshes with rack plate one and rack plate two.

[0016] The present invention has the following beneficial effects:

[0017] (1) Compared with the existing bone marrow aspiration operation using a bone needle and syringe, the present invention sets a fixing sleeve and an adjusting sleeve on the bone marrow aspiration device, and uses an adhesive mechanism to attach the fixing sleeve and adjusting sleeve to the outside of the bone marrow aspiration wound. After the bone needle is inserted into the appropriate position, the connecting rod is moved by rotating the adjusting sleeve, thereby putting the locking kit on the locking base and fixing the outside of the bone needle through the locking base. Thus, through the indirect cooperation of the adhesive mechanism, the fixing sleeve and the adjusting sleeve, the bone needle is limited, reducing the probability of the bone needle shaking and deviating during the bone marrow aspiration process, and ensuring the safety of bone marrow aspiration.

[0018] (2) During the use of this invention, after the bone marrow extraction is completed, the locking sleeve can be moved away from the locking base by rotating the adjusting sleeve counterclockwise, thereby releasing the locking of the bone needle and making it easier to remove the bone needle. After the bone needle leaves the patient's body and moves away from the adjusting sleeve, the adjusting sleeve can be rotated counterclockwise, and then the wound dressing plate can be rotated by the adjusting rod and the arc strip, so that the wound dressing plate can be rotated to a suitable angle and complete the coverage of the wound. This allows for timely treatment of the wound, avoids bleeding, and reduces the time the wound is in contact with the external environment, which can also reduce the probability of wound infection and ensure the safety of bone marrow extraction.

[0019] (3) In the process of using the present invention, when the adjusting sleeve is rotated clockwise, the locking base and the bone needle are fixed by the locking kit. Then, the adjusting sleeve is rotated clockwise to drive the rack plate one to rise. Under the action of the connecting gear, the rack plate two is moved, which in turn drives the semicircular plate to fall. The semicircular plate drives the locking base to fall, thereby driving the bone needle to move. This allows the position of the bone needle to be adjusted, thereby accurately controlling the puncture position of the bone needle and improving the accuracy of bone marrow extraction.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-8As shown, this invention is a bone marrow aspiration device for leukemia patients, including an aspiration needle 4 for puncturing and aspirating bone marrow from the patient. A reinforcing mechanism is provided outside the aspiration needle 4, consisting of an adhesive component and a limiting component. The adhesive component is used to adhere and fix the entire reinforcing mechanism to the patient's skin. The limiting component consists of a fixing sleeve 1 and an adjusting sleeve 2. The fixing sleeve 1 is connected to the adhesive component, and the adjusting sleeve 2 is fitted onto the fixing sleeve 1. The fixing sleeve 1 has external threads, and the inner ring of the adjusting sleeve 2 has internal threads. The screw thread has internal and external threads connected. The fixed sleeve 1 is equipped with a locking base 6, and the adjusting sleeve 2 is equipped with a locking kit. The locking base 6 and the locking kit work together to lock and fix the extraction needle tube. Both the fixed sleeve 1 and the adjusting sleeve 2 are made of transparent acrylic material. By making the material transparent, it is convenient for the operator to observe. The outer side of the adjusting sleeve 2 is provided with a protrusion to facilitate the operator's rotation. The top of the adjusting sleeve 2 is provided with an opening. The opening can prevent the rotation of the adjusting sleeve 2 from obstructing the extraction needle tube 4.

[0034] A semicircular plate 5 is slidably mounted on the fixed sleeve 1. A locking base 6 is set on the semicircular plate 5. The locking base 6 is composed of multiple locking strips arranged in a ring. The locking strips are deformable. The locking kit consists of a locking ring 8 and a connecting rod 7. The locking ring 8 is located below the locking base 6. The connecting rod 7 is mounted on the locking ring 8. One end of the connecting rod 7 is rotatably connected to the adjusting sleeve 2. The top of the locking ring 8 is shaped like a bucket. A sliding rod is installed on the fixed sleeve 1. The sliding rod passes through the semicircular plate 5 and is slidably connected to the semicircular plate 5. A return spring is sleeved on the sliding rod. The top end of the return spring is connected to the semicircular plate 5, and the bottom end of the return spring is connected to the fixed sleeve 1. Thus, the semicircular plate 5 can be restored to its original state without being pressed by external force.

[0035] The adhesive assembly consists of an adjustment plate and an adhesive plate 3. The adjustment plate is mounted on the fixed sleeve 1, and the adhesive plate 3 is rotatably mounted on the adjustment plate. An adhesive medium is provided on one side of the adhesive plate 3. In actual use, the adhesive medium can be medical glue.

[0036] The fixing sleeve 1 is provided with a wound covering 9, which is used to cover and adhere the wound after the needle is withdrawn. The adjusting sleeve 2 is provided with an adjusting component, which is used to adjust the position of the wound covering 9. The wound covering 9 is composed of a wound adhering plate, and a medical drug is provided at the bottom of the wound adhering plate. The medical drug in this invention can be a disinfectant or a drug that helps wound healing. The adjusting component consists of an arc-shaped strip 10, an adjusting rod 11, and an abutment head. The arc-shaped strip 10 is located at the top of the wound adhering plate, and the top of the arc-shaped strip 10... The part has a groove, and the bottom inner wall of the groove is set as an inclined surface. The adjusting rod 11 is slidably installed on the adjusting sleeve 2. The contact head is installed at the bottom end of the adjusting rod 11. The contact head extends into the groove and contacts the inclined surface. A connecting block is installed inside the fixing sleeve 1. An arc-shaped rod is installed on the connecting block. A sliding block is installed on the top of the wound dressing plate. The arc-shaped rod passes through the sliding block and is slidably connected to the sliding block. An arc-shaped spring is sleeved on the arc-shaped rod. One end of the arc-shaped spring is connected to the corresponding connecting block, and the other end of the arc-shaped spring is slidably connected to the sliding block.

[0037] The connecting rod 7 adopts a segmented structure, with the upper segment being connecting support rod one 701 and the lower segment being connecting support rod two 702. A connecting cylinder 703 is installed at the top of connecting support rod two 702. The bottom end of connecting support rod one 701 extends into the connecting cylinder 703 and is slidably connected to it. A sliding disc is installed at the bottom end of connecting support rod one 701, and the sliding disc is slidably connected to the inner wall of the connecting cylinder 703. A reinforcing spring is sleeved on connecting support rod one 701, with the bottom end of the reinforcing spring connected to the sliding disc and the top end of the reinforcing spring connected to the inner wall of the connecting cylinder 703. A rack plate 12 is slidably mounted on the adjusting sleeve 2, and a rack plate 23 is mounted on the top of the semi-circular plate 5. A connecting gear 14 is rotatably mounted on the fixed sleeve 1. The connecting gear 14 meshes with the rack plate 12 and the rack plate 23. In the initial state, the rack on the rack plate 12 does not contact the connecting gear 14 and there is a certain distance between them. The rack plate 12 will contact the connecting gear 14 and drive the connecting gear 14 to rotate after it rises to a suitable height. In the initial state, the rack on the rack plate 23 is connected to the connecting gear 14.

[0038] In this invention, a T-shaped annular groove is provided on the top inner wall of the adjusting sleeve 2. A T-shaped block is provided on the top of the connecting rod 7, the rack plate 12, and the adjusting rod 11. The T-shaped block is in a sliding connection with the inner wall of the T-shaped annular groove, and the T-shaped block is in a rotatable connection with the adjusting sleeve 2. A limit plate is provided on the fixed sleeve 1. The adjusting rod 11 passes through the limit plate and is slidably connected with the limit plate. The movement of the adjusting rod 11 is limited by the limit plate. Similarly, the semi-circular plate 5 limits the connecting rod 7 and the rack plate 12.

[0039] In the process of using this invention, the fixing sleeve 1 and adjusting sleeve 2 are first installed at the patient's puncture position using the adhesive plate 3. Then, the extraction needle tube 4 is passed through the semicircular plate 5 and the locking base 6 for puncture. After the extraction needle tube 4 is inserted into the appropriate position, the adjusting sleeve 2 can be rotated counterclockwise to move it away from the fixing sleeve 1, thereby moving the connecting rod 7 and then the locking kit. The locking kit locks the locking base 6, thus fixing the extraction needle tube 4. This indirectly makes the connection between the extraction needle tube 4 and the fixing sleeve 1 more stable, thereby reducing the probability of the extraction needle tube 4 shifting due to shaking during bone marrow extraction. When it is necessary to adjust the position of the extraction needle tube 4, the adjusting sleeve 2 can be rotated counterclockwise to move the rack plate 12. With the cooperation of the connecting gear 14 and the rack plate 13, the semicircular plate 5 is moved, thereby pushing the extraction needle tube 4 to move. This method can improve the accuracy of the movement of the extraction needle tube 4.

[0040] After bone marrow extraction is completed, the adjusting sleeve 2 is first rotated clockwise to return it to its initial position. Then, the extraction needle 4 is removed from the adjusting sleeve 2. At the same time, the adjusting sleeve 2 is rotated to push the adjusting rod 11 to move. Under the action of the arc-shaped strip 10, the wound covering 9 is pushed to rotate, thus covering the puncture wound and completing the wound treatment. This avoids prolonged contact between the wound and the external environment, ensuring the safety of bone marrow puncture.
