[0001] The present invention relates to the technical field of puncture equipment, and in particular to a bone marrow puncture infusion device. Background Art

[0002] Bone marrow cavity infusion is an emergency infusion method established under special circumstances. It is a method of using the rich vascular network in the bone marrow cavity to inject drugs and liquids into the blood circulation through the bone marrow cavity. Bone marrow cavity infusion often uses a bone marrow puncture device. The existing bone marrow puncture device includes a puncture part and an infusion part. The puncture part is composed of a puncture seat and a puncture needle. The puncture needle is installed on the puncture seat. The infusion part is composed of an infusion seat and an infusion tube fixed on the infusion seat. The puncture seat and the 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. In addition, 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 time increases. The existing puncture needle device is also not designed with a matching puncture needle removal device, and bone marrow puncture is often laborious and difficult to remove. Finally, the existing puncture needles are often of fixed depth and there is no 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. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a bone marrow puncture infusion device to solve the technical problems that the existing puncture equipment is not convenient for controlling the insertion depth of the puncture needle according to the different parts of the human body and the differences in body size, and the infusion effect is poor.

[0005] The present invention is achieved through the following technical solutions:

[0006] A bone marrow puncture and infusion device comprises a puncture part and an infusion part.

The puncture seat and the infusion seat are detachably connected, the puncture needle is inserted through the infusion tube, the puncture needle has a drill bit at one end away from the puncture seat, and a plurality of adjustment gaskets are arranged on the infusion tube.

[0007] Furthermore, the infusion tube is provided with scale lines for measuring the puncture depth, and the scale lines are arranged along the length direction of the infusion tube.

[0008] Furthermore, the drill bit is a multi-blade drill bit having at least three cutting edges.

[0009] Furthermore, the multi-edge drill bit has three or four cutting edges, and the three or four cutting edges are evenly distributed on the drill bit.

[0010] Furthermore, an outer wall of the infusion tube away from one end of the infusion seat is provided with a through hole communicating with the interior of the infusion tube.

[0011] Furthermore, the puncture seat has a rotating portion at one end away from the puncture needle.

[0029] See also Figure 1-5The present invention provides a technical solution: a 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 is detachably connected to the infusion seat 3, 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 plurality of adjustment gaskets 6 are arranged on the infusion tube 4.

[0030] When in 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 an 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, then 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, and the scale line 12 is arranged along the length direction of the infusion tube 4.

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

[0036] In this embodiment, the puncture seat 1 has a rotating part at one end away from the puncture needle 2. Specifically, the rotating part 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 is protruded away from the puncture needle 2 on the side away from the puncture needle 2. By providing the rotating part, the puncture seat 1 can be rotated by using an existing external tool, 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 is provided to facilitate the rotation of the puncture seat 1.

[0039] Furthermore, the handle is provided with a threaded sleeve, the threaded sleeve is provided with an internal thread, the puncture seat is provided with an external thread, and the threaded sleeve and the puncture seat are connected by threaded cooperation. When in use, the threaded sleeve is rotated to make the threaded sleeve and the puncture seat threadedly connected. The threaded sleeve is provided to ensure a stable connection between the handle and the puncture seat. After the infusion is completed, the puncture seat is moved by pulling the handle, and the puncture needle is moved synchronously, which is convenient for pulling out the puncture needle.

[0040] In this embodiment: the handle 7 is provided with an acceleration assembly, which includes a rotating tube 8 sleeved on the outside of the handle 7, and a driving hand wheel 10 is provided at one end of the rotating tube 8 away from the handle 7, and a multi-stage gear acceleration box 9 is provided between the handle 7 and the driving hand wheel 10. There are two groups of gear acceleration boxes, which are respectively a first gear acceleration box and a second gear acceleration box. The first gear acceleration box includes a first box body, and a first gear and a second gear meshing with each other are provided inside the first box body. The diameter of the first gear is greater than the diameter of the second gear. The first gear is fixedly connected to the axis of the driving hand wheel through a first connecting rod. The second gear acceleration box includes a second box body, and a third gear and a fourth gear meshing with each other are provided inside the second box body. The diameter of the third gear is greater than the diameter of the fourth gear. The second gear is fixedly connected to the third gear through a second connecting rod, and the fourth gear is fixedly connected to the axis of the handle through a third connecting rod. When the driving hand wheel is rotated, the first gear drives the second gear to rotate, the second gear drives the third gear to rotate, the third gear drives the fourth gear to rotate, and the fourth gear finally drives the handle to rotate. After the multi-stage acceleration of the gears, the drilling speed of the drill bit 5 is faster.

[0041] Furthermore, a rotating rod is hinged on the outside of the driving hand wheel, and the rotating rod can be folded on the outer wall of the rotating tube by rotating it. By providing the rotating rod, more effort is saved when rotating the driving hand wheel.
