Description

Technical Field

[0001] The utility model relates to the technical field of puncture equipment, in particular to a novel bone marrow puncture infusion device. Background Art

[0002] Intraosseous infusion (IBI) is an emergency infusion method established in special circumstances. It utilizes the rich vascular network within the bone marrow cavity to deliver medications and fluids into the bloodstream. IBI often uses a bone marrow puncture device. Existing IBIs consist of a puncture unit and an infusion unit. The puncture unit consists of a puncture seat and a puncture needle, which is mounted on the puncture seat. The infusion unit consists of an infusion seat and an infusion tube fixed to the infusion seat. The puncture seat and infusion seat are detachably connected, and the puncture needle is inserted through the infusion tube.

[0003] When the above-mentioned puncture device is in use, the existing cutting edge design of the puncture needle surface is not conducive to rapid needle insertion, and puncture is laborious. The stability after insertion is poor, and the drill hole is easily enlarged, causing leakage of rescue drug infusion, and easily causing complications such as soft tissue necrosis. In addition, there is no side hole at the front end of the existing puncture needle. When the needle is inserted too deep or the front end of the needle is blocked, the infusion will not be able to continue. In addition, the existing manual drive device for the puncture needle does not have an acceleration effect, which makes the puncture slow and the patient's pain experience lasts longer. The existing puncture needle device is also not designed with a matching puncture needle removal device, and bone marrow needle removal is often laborious and difficult. Finally, the existing puncture needles are often of fixed depth and do not have a design that can adjust the depth. Clinically, part of the needle tube is often exposed, and there is a risk of bending or breaking. The above defects will make the puncture effect extremely poor. Utility Model Content

[0029] See also Figure 1-5 The utility model provides a technical solution: a new type of bone marrow puncture and infusion device, including a puncture part and an infusion part. The puncture part is composed of a puncture seat 1 and a puncture needle 2. The puncture needle 2 is installed on the puncture seat 1. The puncture part is responsible for accurately puncturing the bone marrow cavity. The infusion part is composed of an infusion seat 3 and an infusion tube 4 fixed on the infusion seat 3. The infusion part is responsible for delivering medicine or nutrient solution into the patient's body. The puncture seat 1 and the infusion seat 3 are detachably connected. The puncture needle 2 is inserted through the infusion tube 4. The puncture needle 2 has a drill bit 5 at the end away from the puncture seat 1, and a number of adjustment gaskets 6 are provided on the infusion tube 4.

[0030] During use, first insert the puncture needle 2 into the infusion tube 4, so that the drill bit 5 of the puncture needle 2 passes through the end of the infusion tube 4 close to the infusion seat 3 to the end of the infusion tube 4 away from the infusion seat 3, and then connect the puncture seat 1 with the infusion seat 3. Then find the bone marrow puncture site of the patient's body and determine a suitable puncture depth according to the patient's puncture site. Then, add the adjustment gasket 6 to the infusion tube 4 according to the puncture depth. Then, insert the puncture needle 2 into the patient's body and continuously rotate the puncture seat 1. The puncture seat 1 will drive the puncture needle 2 to rotate, and drill into the bone marrow cavity during the continuous rotation of the drill bit 5 of the puncture needle 2. Subsequently, remove the puncture seat 1, connect the infusion device to the infusion seat 3 for infusion, and remove the infusion seat 3 after the infusion is completed for hemostasis.

[0031] By adding an adjusting gasket 6 to the infusion tube 4, the puncture depth of the puncture needle 2 can be controlled, so that the insertion depth of the puncture needle 2 can be controlled according to different parts of the human body and differences in body size, so as to achieve a better infusion effect.

[0032] In this embodiment: a scale line 12 for measuring the puncture depth is provided on the infusion tube 4. The scale line 12 is arranged along the length direction of the infusion tube 4. The scale line 12 enables medical staff to more accurately control the puncture depth during the puncture process, further improving the effectiveness of treatment.

[0033] In this embodiment, the drill bit 5 is a multi-blade drill bit 5 having at least three cutting edges 13. The multiple cutting edges 13 of the multi-blade drill bit 5 not only increase drilling speed but also allow for self-grinding during the drilling process, stabilizing the drilling speed of the drill bit 5. Furthermore, the multiple cutting edges 13 of the multi-blade drill bit 5 enable more efficient chip removal, reducing the risk of clogging, and thus maintaining smooth drilling.

[0034] In this embodiment, the multi-edge drill bit 5 has three or four cutting edges 13 evenly distributed across the drill bit 5. This even distribution of cutting edges allows for more even distribution of cutting forces, ultimately resulting in a smoother hole. The three or four-edge configuration allows for adaptability based on bone quality.

[0035] In this embodiment, a through hole 14 is formed on the outer wall of the end of the infusion tube 4 away from the infusion seat 3, communicating with the interior of the infusion tube 4. During infusion, the liquid medicine can flow out not only from the end of the infusion tube 4 but also from the through hole 14. Even if the end of the infusion tube 4 is blocked, the liquid medicine can still flow into the bone marrow cavity through the through hole 14, thus improving the stability of the infusion through the infusion tube 4.

[0036] In this embodiment, the puncture seat 1 has a rotating portion on the end away from the puncture needle 2. Specifically, the rotating portion is a regular hexagonal groove that is recessed toward the puncture needle 2 on the side away from the puncture needle 2, or a regular hexagonal protrusion that protrudes away from the puncture needle 2 on the side away from the puncture needle 2. The provision of the rotating portion allows the puncture seat 1 to be rotated using existing external tools, making it more practical.

[0037] In this embodiment, a needle cap 11 is provided on the infusion tube 4. By providing the needle cap 11, the accidental injury of the drill 5 can be reduced.

[0038] In this embodiment, a handle 7 is provided on the puncture seat 1. The handle 7 facilitates the rotation of the puncture seat 1.

[0039] Furthermore, the handle is provided with a threaded sleeve, which is internally threaded, and the puncture seat is externally threaded, and the threaded sleeve and the puncture seat are connected by a threaded fit. During use, the threaded sleeve is rotated to threadably connect the threaded sleeve and the puncture seat. The threaded sleeve ensures a stable connection between the handle and the puncture seat. After the infusion is completed, the handle is pulled to move the puncture seat, which in turn moves the puncture needle, facilitating the removal of the puncture needle.

[0040] In this embodiment, the handle 7 is provided with an acceleration assembly comprising a rotating tube 8 sleeved onto the outside of the handle 7. A driving handwheel 10 is provided on the end of the rotating tube 8 away from the handle 7. A multi-stage gear accelerator 9 is disposed between the handle 7 and the driving handwheel 10. The gear accelerators are two sets, namely a first gear accelerator and a second gear accelerator. The first gear accelerator comprises a first housing, within which are intermeshing first and second gears. The first gear has a larger diameter than the second gear and is fixedly connected to the axis of the driving handwheel via a first connecting rod. The second gear accelerator comprises a second housing, within which are intermeshing third and fourth gears. The third gear has a larger diameter than the fourth gear and is fixedly connected to the third gear via a second connecting rod. The fourth gear is fixedly connected to the axis of the handle via a third connecting rod. Rotating the driving handwheel causes the first gear to rotate the second gear, which in turn drives the third gear, which in turn drives the fourth gear, which ultimately drives the handle. This multi-stage acceleration of the gears increases the drilling speed of the drill bit 5.

[0041] Furthermore, a rotating rod is hinged on the outside of the driving handwheel, and rotating the rotating rod can fold the rotating rod onto the outer wall of the rotating tube. By providing the rotating rod, more effort is saved when rotating the driving handwheel.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
