Description

Technical Field

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

[0002] Intraosseous infusion is a method of infusion designed specifically for emergency situations. Its core principle is to utilize the dense network of blood vessels within long bones, namely the rich vascular system within the intraosseous cavity, as a direct route to quickly deliver the required medications and fluids into the bloodstream. Scientific research has confirmed that fluids delivered through the intraosseous cavity can quickly reach the central circulatory system, at a rate comparable to direct infusion through a central vein and significantly faster than infusion through a peripheral vein.

[0003] At present, when a puncture needle enters the human bone marrow for infusion, the puncture needle is generally fixed directly by medical tape. The puncture needle body has the same appearance as the puncture needle and the infusion adapter block in the prior art CN210903259U. However, since the main part of the puncture needle is not attached to the skin but is perpendicular to the skin, the fixing effect achieved only by the tape is not ideal. Some medical staff use a press-type buckle to fix the puncture needle, but this method will cause secondary damage to the puncture site and it is not convenient to separate it from the puncture needle body later. Therefore, we propose a new device for fixing bone marrow puncture and infusion needles. Utility Model Content

The positioning mechanism is used to fix and position the puncture needle connection part. The positioning mechanism includes a penetrating piece and an auxiliary piece. The top of the medical tape is provided with a penetrating piece, and the inner side of the penetrating piece is assembled with an auxiliary piece.

[0007] Preferably, the penetration piece includes an inner interface, an L-shaped support piece and a fixing ring. The top of the medical tape is provided with an inner interface, and the inner interface is gap-fitted with the puncture needle connecting part. A plastic ring piece is fixed to the top of the medical tape and located outside the inner interface. L-shaped support pieces are fixed at both ends of the top of the plastic ring piece, and a fixing ring is fixed at one end of the two L-shaped support pieces.

[0008] Preferably, the auxiliary part includes a threaded sleeve, a threaded sheet and a rotating ring. The threaded sleeve is fixed to the bottom of the fixed ring. A plurality of threaded sheets are evenly and integrally fixed to the bottom of the threaded sleeve. The outer side of the threaded sleeve is threadedly connected to the rotating ring, and the threaded sheets are all threadedly connected to the rotating ring.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Example 1

[0025] Reference Figure 1-3 A new device for fixing a bone marrow puncture infusion needle comprises a medical tape 1 assembled on a puncture needle connection part 2, a needle 3 is provided at the bottom of the puncture needle connection part 2, and a positioning mechanism is equipped on the top of the medical tape 1. The positioning mechanism is used to fix and position the puncture needle connection part 2. The positioning mechanism comprises a penetrating piece and an auxiliary piece. A penetrating piece is provided on the top of the medical tape 1, and an auxiliary piece is equipped on the inner side of the penetrating piece. It can be understood that the top of the puncture needle connection part 2 is connected to an external infusion device, which facilitates infusion to the patient through the puncture needle connection part 2 and the needle 3.

[0026] The penetration piece includes an inner interface 4, an L-shaped support piece 5 and a fixing ring 6. The inner interface 4 is opened at the top of the medical tape 1, and the inner interface 4 is loosely matched with the puncture needle connecting part 2. A plastic ring piece is fixed to the top of the medical tape 1 and located outside the inner interface 4. L-shaped support pieces 5 are fixed at both ends of the top of the plastic ring piece. A fixing ring 6 is fixed at one end of the two L-shaped support pieces 5. The setting of the L-shaped support piece 5 can provide support for the fixing ring 6.

[0027] The auxiliary parts include a threaded sleeve 7, a threaded piece 8 and a rotating ring 9. The threaded sleeve 7 is fixed to the bottom of the fixed ring 6. A plurality of threaded pieces 8 are evenly and integrally fixed to the bottom of the threaded sleeve 7. The outer side of the threaded sleeve 7 is threadedly connected to the rotating ring 9. The threaded pieces 8 are all threadedly connected to the rotating ring 9. It can be understood that the inner diameter of the threaded sleeve 7 is smaller than the diameter of the puncture needle connecting part 2.

[0028] There is an acute angle between the threaded pieces 8 and the vertical direction. The diameter of the circle enclosed by the bottoms of the multiple threaded pieces 8 is larger than the diameter of the puncture needle connecting portion 2.

[0029] Buffer gaps 12 are provided between the multiple threaded sheets 8. The setting of the buffer gaps 12 facilitates the position change of the multiple threaded sheets 8 and gathers toward the center of the threaded sleeve 7. The cross-section of the threaded sheet 8 is trapezoidal and gradually becomes thicker from top to bottom.

[0030] Example 2

[0031] Further optimize Example 1, specifically, as Figure 3-4 As shown, an auxiliary ring 10 is fixed to the outer side of the rotating ring 9 . The auxiliary ring 10 facilitates the user to rotate the rotating ring 9 .

[0032] A plurality of anti-skid rubber particles 11 are evenly distributed and fixed on one side of the threaded piece 8 close to the center of the threaded sleeve 7. The setting of the anti-skid rubber particles 11 can increase the friction between the threaded piece 8 and the puncture needle connecting part 2, so that the threaded piece 8 has a better fixing effect on the puncture needle connecting part 2.

[0033] From the above, we can know that:

[0034] The present invention addresses the following technical issues: Since the main body of the puncture needle is not attached to the skin but is perpendicular to the skin, the fixation effect achieved by tape alone is not ideal. Some medical staff use a press-type buckle to fix the puncture needle, but this method can cause secondary damage to the puncture site and is not easy to separate from the puncture needle body later. The technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solution is as follows:

[0035] During use, the needle 3 is first punctured into the patient's skin. At this time, the puncture needle connecting part 2 is in contact with the patient's skin. Then the medical tape 1 is sleeved on the outside of the puncture needle connecting part 2 through the inner interface 4, and the medical tape 1 is adhered to the patient's skin. Then the auxiliary ring 10 is rotated so that the auxiliary ring 10 drives the rotating ring 9 to rotate. Because the rotating ring 9 is threadedly connected to the threaded sleeve 7 and the threaded piece 8, multiple rotating rings 9 can gradually approach the threaded piece 8 along the outside of the threaded sleeve 7. When the rotating ring 9 is connected to the threaded piece 8, the threaded piece 8 is guided by the rotating ring 9 and gradually gathers in the direction close to the center of the threaded sleeve 7 until the threaded piece 8 is in contact with the puncture needle connecting part 2, so that multiple threaded pieces 8 form a fixation for the puncture needle connecting part 2.

[0036] Through the above configuration, this application can certainly solve the above technical problems and achieve the following technical effects:

[0037] The present invention uses the structural design of the positioning mechanism and the medical tape 1 to make it easy for the device to position and fix the puncture needle connecting part 2 of different diameters, and can stably fix the puncture needle connecting part 2 on the patient's skin surface, which is convenient for subsequent infusion work. At the same time, it can be easily separated from the puncture needle connecting part 2 at a later stage, thereby speeding up work efficiency and improving the flexibility of the device.
